Abstract: Low-frequency repetitive transcranial magnetic stimulation (LF-rTMS) protocols targeting primary motor cortex (M1) are used in rehabilitation of neurological diseases for their therapeutic potential, safety, and tolerability. Although lower intensity LF-rTMS can modulate M1 neurophysiology, results are variable, and a systematic assessment of its dose effect is lacking. To determine the dose-response of LF-rTMS on stimulated and non-stimulated M1. In a sham-controlled randomized double-blind crossover study the effect of LF-TMS protocols were determined in 20 right-handed older healthy participants. In 3 sessions, 1 Hz rTMS at 80% (rTMS), 90% (rTMS) of motor threshold or sham stimulation were applied to left upper extremity M1. Outcome measures were curve parameters of the stimulus-response curve (maximum motor evoked potential [MEP], slope and the intensity to evoke 50% MEP), short-interval intracortical inhibition (SICI), and interhemispheric inhibition (IHI). Within LF-rTMS sessions, rTMS, increased MEP in the stimulated M1. Furthermore, rTMS, increased the slope in the non-stimulated M1. LF-rTMS effects on SICI were dependent on the participants' baseline SICI, hemisphere, and intensity of conditioning pulse. Finally, rTMS increased whereas rTMS decreased IHI, for both IHI directions. These changes were dependent on baseline IHI and hemisphere and were no longer significant when baseline IHI was accounted for. Intensity of subthreshold LF-rTMS has differential effects on excitation and inhibition of stimulated and non-stimulated M1. The effects were small and were only demonstrated within the LF-rTMS sessions but were not different when compared to sham. rTMS related changes in SICI and IHI were dependent on baseline level.

Abstract Summary: Scientists did a study to see how a special kind of low-strength brain stimulation affects the part of the brain that controls movement. They used a machine to send magnetic pulses to the brains of 20 older people who were right-handed. They did this three times with different strengths or a pretend (sham) treatment. They measured how the brain's movement area responded, both where they stimulated and on the other side of the brain.
They found that the brain's response changed a little bit when they used the magnetic pulses, but these changes were not very big and were only seen during the treatment. The changes depended on how the person's brain worked before the treatment. The results help us understand how this brain stimulation works, but more research is needed to see how it can help people with brain diseases.

Abstract: This study investigates the impact of habitual late calorie intake on glucose metabolism in adults with overweight or obesity and diet or metformin-controlled prediabetes or type 2 diabetes independently of body weight, fat mass, energy intake or diet composition. Participants (n = 26) were classified as Later Eaters (LE) if ≥45% daily calories were consumed after 5 pm and Early Eaters (EE) if not, based on daily caloric intake assessed over 2-wk. EE and LE did not differ in anthropometrics or daily energy intake, but LE consumed more carbohydrates (p = 0.038) and fats (p = 0.039) after 5 pm. Fasting glucose, insulin, and C-peptide did not differ between groups but LE exhibited higher glucose concentrations after an oral glucose tolerance test (p = 0.001), even after adjusting for body weight, fat mass, energy intake and diet composition (p < 0.05). Glucose results remained when participants with T2D were excluded (p = 0.031). After diabetes status adjustment, differences in glucose concentrations were higher in LE for time 30 (p = 0.028) and 60 min (p = 0.036). LE, compared to EE, had poorer glucose tolerance, independent of body weight, fat mass, daily energy intake and diet composition. ClinicalTrials.gov: NCT04465721.
Abstract Summary: Scientists did a study to see if eating late affects blood sugar levels in people who are a bit heavy and have early signs of diabetes or actual diabetes, but are keeping it under control with diet or medicine. They had 26 people join the study. Some ate most of their food after 5 pm (Later Eaters), and some did not (Early Eaters). They found that the Later Eaters and Early Eaters were similar in size and how much they ate every day, but Later Eaters had more carbs and fats after 5 pm. When they checked their blood sugar levels after drinking a sugary drink, the Later Eaters had higher blood sugar levels, even when the scientists considered their weight, body fat, how much they ate, and what they ate. This was true even for those who didn't have full-blown diabetes yet. The study shows that eating late might make it harder for the body to handle sugar, which is important for everyone to know, especially people who are trying to avoid diabetes or manage it.

Safety behavior reduction for appearance concerns: A randomized controlled trial of a smartphone-based intervention.

Abstract: Appearance concerns are a core feature of multiple psychiatric disorders (i.e., body dysmorphic disorder, eating disorders, and social anxiety disorders). Individuals with these concerns commonly engage in appearance-related safety behaviors (ARSB), behaviors intended to avoid, prevent, or manage the negative evaluation of one's physical appearance. The present study evaluated a brief ARSB reduction intervention for appearance concerns. Women with elevated appearance concerns ( = 203) were recruited from across the United States and randomized to receive one of two 1-month smartphone-based interventions targeting ARSBs or unhealthy behaviors (UHBs). Both consisted of daily text messages with links to behavior checklists and reminders to avoid the respective behaviors. Participants in both treatments saw substantial reductions in symptoms. Though the UHB fading condition showed significantly better treatment adherence than ARSB fading, ARSB fading led to significantly lower appearance concerns (² = .028, = .014) and eating disorder symptoms (² = .024, = .020) at posttreatment, and lower appearance concerns (² = .041, = .004), eating disorder symptoms (² = .029, = .006), social anxiety (² = .048, = .005), and appearance importance at 1-month follow-up (² = .042, = .011), relative to UHB fading. Changes in ARSBs were found to partially mediate the effect of treatment on appearance concerns. These preliminary findings provide novel evidence for the efficacy of targeting ARSBs and suggest that this text-based intervention may be an efficacious and accessible intervention for women with elevated appearance concerns.

Abstract Summary: Scientists did a study to help women who worry a lot about how they look. These worries can be part of different mental health problems. The women in the study got one of two kinds of help through their smartphones for a month. Both groups got daily texts with checklists and reminders to stop certain behaviors. One group focused on stopping actions that were about hiding or fixing their looks to feel better (like wearing lots of makeup). The other group worked on stopping unhealthy behaviors that weren't about looks. In the end, the group that worked on looks-related actions felt better about their looks and had fewer eating and social worries, even after the study ended. The study shows that getting help through texts could be a good way for women to feel better about how they look.

Abstract: Diet is considered a first-line treatment option for prediabetes, a condition that affects 96 million United States (U.S.) adults. Diet patterns that prioritize whole foods (e.g., Mediterranean) are currently recommended to treat prediabetes. However, no studies have tested whether a U.S.-style diet pattern that prioritizes whole foods can be used to treat prediabetes. The purpose of this study was to assess the feasibility and acceptability of a whole foods diet for adults with prediabetes and their offspring prior to conducting a larger clinical trial. A 2-week single-arm pre-post experimental controlled-feeding intervention of a 2020-2025 Dietary Guidelines for Americans adapted whole foods diet (e.g., primarily focused on foods that have undergone limited processing or refinement) was conducted in adults (25-59 years) with prediabetes and their biological offspring (6-17 years). Families received 2 weeks of menus and grocery delivery and weekly counseling by a registered dietitian. Families were invited to attend an optional focus group session. Feasibility was based on having a ≥ 50% family completion rate with ≥ 80% completion of study outcomes. Measures included adult-child anthropometrics (weight [kg], body mass index [BMI] including BMI% and Z-scores for offspring, waist circumference [cm]) and child diet quality estimated using the 2015 Healthy Eating Index (HEI) from a single random food record. Wilcoxon signed rank was used to compare differences between baseline and 2-week anthropometrics measures and offspring total HEI scores. Qualitative data were analyzed using thematic analysis to understand factors attributed to diet adherence and acceptability. Eight families enrolled (n = 8 adults, n = 12 offspring), with 7 families completing the study (12% attrition) and completing 100% of study outcome measures. Adults experienced a median weight loss of - 1.0 kg from baseline to 2 weeks (79.5 kg to 78.5 kg). Offspring had a 24-point increase in total 2015 HEI scores (median difference 50 to 74). Focus group participants (n = 4 adults) reported being satisfied with the program and expressed a willingness to continue the diet despite identified barriers. A whole foods diet that provides dietary support was found to be feasible and acceptable for families at risk for T2D. Future studies are needed to test the effects of the diet on prediabetes outcomes, diet quality, and diet adherence in adults and families. NCT05483972 at ClinicalTrials.gov. Registered July 25, 2022. https://clinicaltrials.gov/study/NCT05483972?cond=prediabetes&term=whole%20foods%20&rank=1.
Abstract Summary: Scientists wanted to see if a special diet full of natural foods, like the kind recommended in the U.S. food guidelines, could help adults and kids who might be close to getting a type of sugar sickness called prediabetes. They gave 8 families food and advice for 2 weeks and checked if they liked the diet and could stick to it. Most families finished the study, and the adults lost a little weight while the kids ate healthier. The families mostly liked the diet even though it was sometimes hard to follow. The study showed that this diet could be good for families who are trying to avoid getting prediabetes, but more research is needed to be sure.

Abstract: Stress related to Alzheimer disease and related dementias (ADRD) is common, particularly among those who care for persons with challenging behaviors and personality or mood changes. Mindfulness and self-compassion programs are efficacious for managing stress. The skills of mindfulness and self-compassion, however, must be integrated with behavioral management skills in order to effectively improve caregiver stress. In this study, we aimed to describe the development of the Mindful and Self-Compassionate Care (MASC) program, the first program that combines mindfulness and self-compassion with behavioral management skills to decrease caregiver stress, and its evaluation in the Supporting Our Caregivers in ADRD Learning (SOCIAL) study. Using the National Institutes of Health (NIH) stage model, we describe 3 phases of work encompassing NIH Stages 1A and 1B. In phase 1, we conducted 5 focus groups (N=28) of stressed individuals caring for persons with ADRD and challenging behaviors. Rapid data analysis informed the development of a 6-week online intervention. Phase 2 (NIH stage 1A) includes an open pilot (N>10) with optional exit interviews. Phase 3 (NIH stage 1B) is a feasibility randomized controlled trial of the intervention versus the Health Education Program control. Primary outcomes focus on feasibility with secondary outcomes encompassing acceptability, credibility, fidelity, and signals of preliminary efficacy. Phase 1 follows traditional recommendations for qualitative analyses (at the point of thematic saturation) which was achieved after 5 focus groups (N=28). For the phase 2 open pilot, up to 12 participants will be recruited. For the phase 3 feasibility study, recruitment of 80 caregivers will allow the assessment of feasibility benchmarks. Data for phase 1 included 5 focus groups. In phases 2 and 3, data collection will occur through REDCap (Research Electronic Data Capture; Vanderbilt University) surveys and an optional qualitative exit interview. Analyses will include hybrid inductive-deductive analyses for qualitative data and assessment of changes in our intervention targets and outcomes using t tests and correlation analyses. In phase 1, caregivers reported interest in a brief, online stress management program. Participants held misconceptions about mindfulness and self-compassion, but after detailed explanation thoughts, these skills could be helpful when directly linked to implementation during caregiving routines. Phases 2 and 3 will be completed by the end of 2025. We describe the protocol for the Supporting Our Caregivers in ADRD Learning study, as well as the development and feasibility testing of the Mindful and Self-Compassionate Care intervention. Future work will include a fully powered efficacy-effectiveness randomized controlled trial. ClinicalTrials NCT05847153; https://clinicaltrials.gov/study/NCT05847153; and ClinicalTrials.gov NCT06276023; https://clinicaltrials.gov/study/NCT06276023. DERR1-10.2196/58356.
Abstract Summary: Scientists are studying a new program called Mindful and Self-Compassionate Care (MASC) to help people who take care of others with Alzheimer's disease and related dementias. These caregivers often feel stressed, especially when dealing with difficult behaviors. The MASC program teaches them how to be calm and kind to themselves while also learning how to manage challenging behaviors.
First, the researchers talked to 28 caregivers in small groups to understand their stress and needs. They used this information to create a 6-week online course. Next, they tested the course with a small group of caregivers to see if it was helpful and easy to use. Finally, they will do a bigger test with 80 caregivers to make sure the program works well.
The caregivers liked the idea of the program and thought it could be useful, especially when they learned how to use the new skills in their daily care routines. The full results of the study will be ready by the end of 2025. This research could lead to better support for caregivers, making their tough job a little easier.

Abstract: Late-life depression (LLD) has been associated cross-sectionally with lower brain structural volumes and accelerated brain aging compared to healthy controls (HC). There are few longitudinal studies on the neurobiological predictors of recurrence in LLD. We tested a machine learning (ML) brain age model and its prospective association with LLD recurrence risk. We recruited individuals with LLD (n=102) and HC (n=43) into a multi-site 2-yr longitudinal study. Individuals with LLD were enrolled within 4 months of remission. Remitted LLD participants underwent baseline neuroimaging and longitudinal clinical follow-up. Over 2 years, 43 LLD participants relapsed (REL) and 59 stayed in remission (REM). We used a previously developed ML brain age algorithm to compute brain age at baseline and we evaluated brain age group differences (HC vs. LLD and HC vs. REM vs. REL). We conducted a Cox proportional hazards model to evaluate whether baseline brain age predicted time to relapse. We found that brain age did not significantly differ between HC and LLD as well as HC, REM, and REL groups. Brain age did not significantly predict time to relapse. In contrast to our hypothesis, we found that brain age did not differ between non-depressed controls and individuals with remitted LLD, and brain age was not associated with subsequent recurrence. This is in contrast to existing literature which has identified baseline brain age differences in late life but in line with work that shows no differences between those who do and do not relapse on gross structural measures.
Abstract Summary: Scientists did a study to see if the age of a person's brain can predict if their depression will come back. They looked at older people who had depression before but were feeling better, and compared them to healthy people. They used a special computer program to guess the age of everyone's brain at the start and then watched to see if the depression came back over two years. They found that the brain's age didn't really change between the healthy people and those who had depression before, and it didn't help guess who would get depressed again. This was surprising because other studies thought the brain's age could be different in older people with depression. This information is important because it tells us that the age of the brain might not be a good way to know if someone's depression will return.

Abstract: Hearing loss is identified as one of the largest modifiable risk factors for cognitive impairment and dementia. Studies evaluating this relationship have yielded mixed results. We investigated the longitudinal relationship between self-reported hearing loss and cognitive/functional performance in 695 cognitively normal (CN) and 941 participants with mild cognitive impairment (MCI) enrolled in the Alzheimer's Disease Neuroimaging Initiative. Within CN participants with hearing loss, there was a significantly greater rate of cognitive decline per modified preclinical Alzheimer's cognitive composite. Within both CN and MCI participants with hearing loss, there was a significantly greater rate of functional decline per the functional activities questionnaire (FAQ). In CN and MCI participants, hearing loss did not significantly contribute to the risk of progression to a more impaired diagnosis. These results confirm previous studies demonstrating a significant longitudinal association between self-reported hearing loss and cognition/function but do not demonstrate an increased risk of conversion to a more impaired diagnosis. NCT00106899 (ADNI: Alzheimer's Disease Neuroimaging Initiative, clinicaltrials.gov), NCT01078636 (ADNI-GO: Alzheimer's Disease Neuroimaging Initiative Grand Opportunity, clinicaltrials.gov), NCT01231971 (ADNI2: Alzheimer's Disease Neuroimaging Initiative 2, clinicaltrials.gov), NCT02854033 (ADNI3: Alzheimer's Disease Neuroimaging Initiative 3, clinicaltrials.gov). Hearing loss is a potential modifiable risk factor for dementia. We assessed the effect of self-reported hearing loss on cognition and function in the ADNI cohort. Hearing loss contributes to significantly faster cognitive and functional decline. Hearing loss was not associated with conversion to a more impaired diagnosis.
Abstract Summary: Scientists studied how hearing loss might affect people's thinking skills and daily activities over time. They looked at two groups of older adults: some with normal thinking skills and some with mild thinking problems. They found that people who said they had trouble hearing also seemed to have their thinking skills and ability to do daily tasks get worse faster than those who didn't report hearing problems. However, hearing loss didn't seem to make it more likely for someone to develop serious thinking problems. This study helps us understand that having trouble hearing might be linked to how well our brains work as we get older.

14(9):e079092.
Abstract: We previously reported global regional differences in smoking cessation outcomes, with smokers of US origin having lower quit rates than smokers from some other countries. This post-hoc analysis examined global regional differences in individual-level and country-level epidemiological, economic and tobacco regulatory factors that may affect cessation outcomes. EAGLES (Evaluating Adverse Events in a Global Smoking Cessation Study) was a randomised controlled trial that evaluated first-line cessation medications and placebo in 8144 smokers with and without psychiatric disorders from 16 countries across seven regions. Generalised linear and stepwise logistic regression models that considered pharmacotherapy treatment, psychiatric diagnoses, traditional individual-level predictors (eg, demographic and smoking characteristics) and country-specific smoking prevalence rates, gross domestic product (GDP) per capita, relative cigarette cost and WHO-derived MPOWER scores were used to predict 7-day point prevalence abstinence at the end of treatment. In addition to several traditional predictors, three of four country-level variables predicted short-term abstinence: GDP (0.54 (95% CI 0.47, 0.63)), cigarette relative income price (0.62 (95% CI 0.53, 0.72)) and MPOWER score (1.03 (95% CI 1.01, 1.06)). Quit rates varied across regions (22.0% in Australasia to 55.9% in Mexico). With northern North America (USA and Canada) as the referent, the likelihood of achieving short-term abstinence was significantly higher in Western Europe (OR 1.4 (95% CI 1.14, 1.61)), but significantly lower in Eastern Europe (0.39 (95% CI 0.22, 0.69)) and South America (0.17 (95% CI 0.08, 0.35)). Increased tobacco regulation was associated with enhanced quitting among participants in the EAGLES trial. Paradoxically, lower GDP, and more affordable cigarette pricing relative to a country's GDP, were also associated with higher odds of quitting. Geographical region was also a significant independent predictor. ClinicalTrials.gov, NCT01456936.
Abstract Summary: Scientists did a study called EAGLES to see why people from different parts of the world quit smoking at different rates. They looked at 8,144 smokers from 16 countries and checked things like how much money people make, how much cigarettes cost, and the rules about smoking in each country. They found that people in places with stricter smoking rules and higher cigarette prices were more likely to stop smoking. Also, in richer countries, fewer people quit smoking. This study helps us understand that making cigarettes more expensive and having strong rules about smoking can help more people quit smoking.

Abstract: Compensatory coping, or maladaptive alterations in behavior with the intention of preventing or managing symptoms, is increasingly being explored as a key factor in how people respond to bladder conditions. Preliminary investigations have identified relations between coping behaviors and psychological distress in urologic conditions, including interstitial cystitis/bladder pain syndrome (IC/BPS). However, previous explorations of coping have not accounted for heterogeneity in coping behaviors or addressed the likelihood that some coping behaviors may be more adaptive than others. This study sought to examine how two specific types of coping behaviors, primary control coping and disengaged coping, are related to distress and symptoms in IC/BPS, and to explore the potential role of pain phenotype in this relationship. A secondary data analysis was conducted with a large community data set (N = 677 women with IC/BPS) and employed descriptive and inferential statistics to characterize coping patterns and explore novel predictors of distress. Results indicated that almost all participants engaged in at least one compensatory coping behavior within the last week. Both types of coping behaviors correlated with psychological symptoms, and when controlling for relevant clinical variables (i.e., age and severity of urinary symptoms), disengaged coping behaviors were significantly associated with psychological distress. Further, the addition of pain phenotype to multiple regression models resulted in a more effective predictive model when considering the relation between coping behaviors and depression. By investigating more deeply the relationship between coping and distress, understanding of potential risk factors and mechanisms is increased, offering valuable insights for intervention strategies for IC/BPS patients.
Abstract Summary: Scientists did a study to learn about how people with a bladder condition called interstitial cystitis/bladder pain syndrome (IC/BPS) deal with their symptoms. They looked at two ways people cope: trying to control the situation or giving up on dealing with it. They used information from 677 women with IC/BPS to see how these coping ways are linked to feeling upset or having more symptoms. They found that almost everyone tried at least one way to cope in the last week. The way people coped was connected to how stressed or depressed they felt. When they also considered the type of pain the person had, they could better predict who would feel depressed. This study helps us understand that the way people try to handle their bladder condition can affect their feelings. Knowing this can help create better ways to support people with IC/BPS.

Myeloid-Specific JAK2 Contributes to Inflammation and Salt Sensitivity of Blood Pressure.

Abstract: Salt sensitivity of blood pressure (SSBP), characterized by acute changes in blood pressure with changes in dietary sodium intake, is an independent risk factor for cardiovascular disease and mortality in people with and without hypertension. We previously found that elevated sodium concentration activates antigen-presenting cells (APCs), resulting in high blood pressure, but the mechanisms are unknown. Here, we hypothesized that APC-specific JAK2 (Janus kinase 2) through STAT3 (signal transducer and activator of transcription 3) and SMAD3 (small mothers against decapentaplegic homolog 3) contributes to SSBP. We performed bulk or single-cell transcriptomic analyses following in vitro monocytes exposed to high salt and in vivo high sodium treatment in humans using a rigorous salt-loading/depletion protocol to phenotype SSBP. We also used a myeloid cell-specific CD11c JAK2 knockout mouse model and measured blood pressure with radiotelemetry after N-omega-nitro-L-arginine-methyl ester and a high salt diet treatment. We used flow cytometry for immunophenotyping and measuring cytokine levels. Fluorescence in situ hybridization and immunohistochemistry were performed to spatially visualize the kidney's immune cells and cytokine levels. Echocardiography was performed to assess cardiac function. We found that high salt treatment upregulates gene expression of the JAK/STAT/SMAD pathway while downregulating inhibitors of this pathway, such as suppression of cytokine signaling and cytokine-inducible SH2, in human monocytes. Expression of the JAK2 pathway genes mirrored changes in blood pressure after salt loading and depletion in salt-sensitive but not salt-resistant humans. Ablation of JAK2, specifically in CD11c APCs, attenuated salt-induced hypertension in mice with SSBP. Mechanistically, we found that SMAD3 acted downstream of JAK2 and STAT3, leading to increased production of highly reactive isolevuglandins and proinflammatory cytokine IL (interleukin)-6 in renal APCs, which activate T cells and increase production of IL-17A, IL-6, and TNF-α (tumor necrosis factor-alpha). Our findings reveal the APC JAK2 signaling pathway as a potential target for the diagnosis and treatment of SSBP in humans.
Abstract Summary: Scientists did a study to understand why some people's blood pressure goes up or down when they eat more or less salt, which can be bad for the heart. They thought that a special part of our cells, called JAK2, might be responsible when it works with other cell parts. To find out, they did a bunch of tests on human blood cells and mice, including checking blood pressure, looking at the heart, and studying how cells behave and talk to each other. They found that when there's a lot of salt, JAK2 makes cells act in a way that raises blood pressure. But when they stopped JAK2 from working in mice, their blood pressure didn't go up with more salt. This means that JAK2 could be a clue to help doctors figure out why some people's blood pressure changes with salt and how to treat it.

Abstract: Few studies have addressed medication adherence in adolescents and young adults (AYAs) with bipolar disorder (BD). This 6-month prospective randomized-controlled trial (RCT) tested customized adherence enhancement for adolescents and young adults (CAE-AYA), a behavioral intervention for AYAs versus enhanced treatment as usual (ETAU). Inclusion criteria were AYAs age 13-21 with BD type I or II with suboptimal adherence defined as missing ≥20% of medications. Assessments were conducted at Screening, Baseline, and weeks 8, 12 and 24. Primary outcome was past 7 day self-reported Tablets Routine Questionnaire (TRQ) validated by electronic pillbox monitoring (SimpleMed). Symptom measures included the Hamilton Depression Rating Scale (HAM-D) and Young Mania Rating Scale (YMRS). The mean sample age (N = 36) was 19.1 years (SD = 2.0); 66.7% (N = 24) female, BD Type I (81%). The mean missed medication on TRQ for the total sample was 35.4% (SD = 28.8) at screening and 30.4% (SD = 30.5) at baseline. Both CAE-AYA and ETAU improved on TRQ from screening to baseline. Baseline mean missed medication using SimpleMed was 51.6% (SD = 38.5). Baseline HAM-D and YMRS means were 7.1 (SD = 4.7) and 6.0 (SD = 7.3), respectively. Attrition rate at week 24 was 36%. Baseline to 24-week change on TRQ, adjusting for age, gender, educational level, living situation, family history, race, and ethnicity, showed improvement favoring CAE-AYA versus ETAU of 15%. SimpleMed interpretation was limited due to substantial missing data. There was a significant reduction in depression favoring CAE-AYA. CAE-AYA may improve adherence in AYAs with BD, although conclusions need to be made cautiously given study limitations. ClinicalTrials.gov identifier: NCT04348604.
Abstract Summary: Scientists did a study to help teenagers and young people who have bipolar disorder take their medicine regularly. They tried a special program called CAE-AYA and compared it to the usual way of helping. They checked if the young people took their medicine using a special pillbox that records when pills are taken and by asking them. They also looked at how the young people felt, checking their mood for signs of depression or mania. They found that the special program might be better at helping these young people take their medicine and feel less depressed. But they're not totally sure because there were some problems with the study, like missing information. They think this program could be helpful, but they need to learn more.

Abstract: The relationship between cerebrovascular disease (CVD) and amyloid beta (Aβ) in Alzheimer's disease (AD) is understudied. We hypothesized that magnetic resonance imaging (MRI)-based CVD biomarkers-including cerebral microbleeds (CMBs), lacunar infarction, and white matter hyperintensities (WMHs)-would correlate with Aβ positivity on positron emission tomography (Aβ-PET). We cross-sectionally analyzed data from the Alzheimer's Disease Neuroimaging Initiative (ADNI, N = 1352). Logistic regression was used to calculate odds ratios (ORs), with Aβ-PET positivity as the standard-of-truth. Following adjustment, WMHs (OR = 1.25) and superficial CMBs (OR = 1.45) remained positively associated with Aβ-PET positivity (p < 0.001). Deep CMBs and lacunes exhibited a varied relationship with Aβ-PET in cognitive subgroups. The combined diagnostic model, which included CVD biomarkers and other accessible measures, significantly predicted Aβ-PET (pseudo-R= 0.41). The study highlights the translational value of CVD biomarkers in diagnosing AD, and underscores the need for more research on their inclusion in diagnostic criteria. gov: ADNI-2 (NCT01231971), ADNI-3 (NCT02854033). Cerebrovascular biomarkers linked to amyloid beta (Aβ) in Alzheimer's disease (AD). White matter hyperintensities and cerebral microbleeds reliably predict Aβ-PET positivity. Relationships with Aβ-PET vary by cognitive stage. Novel accessible model predicts Aβ-PET status. Study supports multimodal diagnostic approaches.
Abstract Summary: Scientists wanted to see if certain signs of blood vessel problems in the brain could help us understand Alzheimer's disease better. They used special brain scans called MRI and PET scans to look at these signs, which include tiny brain bleeds, small strokes, and bright spots on the MRI that show damaged areas. They studied a lot of people's brain scans and found that the bright spots and the tiny bleeds on the surface of the brain were often seen in people who also had signs of Alzheimer's on their PET scans. However, the relationship between these signs and Alzheimer's changed depending on how bad a person's memory and thinking problems were. They created a new way to predict if someone might have Alzheimer's by looking at these brain scan signs and other simple tests. This study helps doctors think about using different kinds of tests to diagnose Alzheimer's disease.

Behav Res Ther.
2024 Nov;
182:104620.
Abstract: Anhedonia, deficits in motivation and pleasure, is a transdiagnostic symptom of psychopathology and negative prognostic marker. In this randomized, parallel-arm clinical trial, a novel intervention, Behavioral Activation Treatment for Anhedonia (BATA), was compared to an individually administered Mindfulness-Based Cognitive Therapy (MBCT) in a transdiagnostic cohort of adults with clinically significant anhedonia (ClinicalTrials.gov Identifiers NCT02874534 and NCT04036136). Participants received 8-15 individual psychotherapy sessions, once weekly, with either BATA (n = 61) or MBCT (n = 55) and completed repeated self-report assessment of anhedonia and other internalizing symptoms. Indicators of treatment feasibility were similar across conditions, though MBCT showed a trend towards greater attrition rates than BATA, with an adjusted odd's ratio of 2.04 [0.88, 4.73]. Treatment effects on the primary clinical endpoint of anhedonia symptoms did not significantly differ, with a 14-week estimated difference on the Snaith Hamilton Pleasure Scale (SHAPS) of -0.20 [-2.25, 1.84] points in BATA compared to MBCT (z = 0.19, p = 0.845, d = 0.05). The expected 14-week change in SHAPS scores across conditions was -7.18 [-8.22, -6.15] points (z = 13.6, p < 0.001, d = 1.69). There were no significant differences in the proportion of participants demonstrating reliable and clinically significant improvements in SHAPS scores, or in the magnitude of internalizing symptom reductions. Limitations included a modest sample size, lack of longer-term follow up data, and non-preregistered analytic plan. There was no evidence to support superior clinical efficacy of BATA over MBCT in a transdiagnostic cohort of adults with elevated anhedonia. Both interventions reduced anhedonia symptoms to a comparable magnitude of other existing treatments.
Abstract Summary: Scientists did a study to help people who have trouble feeling happy or motivated, which can be a sign of different mental health issues. They tested two ways to help: one called Behavioral Activation Treatment for Anhedonia (BATA) and another called Mindfulness-Based Cognitive Therapy (MBCT). Adults who were having these problems tried one of the two methods for a few weeks. They found that both ways helped people about the same amount, and there wasn't one that was better than the other. This is good news because it means there are different options that can help people feel better.

25(1):549.
Abstract: Chronic pain often clusters in families, where parents and their offspring both experience chronic pain conditions. Young children of parents with irritable bowel syndrome (IBS) represent an at-risk group for the development of abdominal pain, disability, and excess health care visits in later childhood. Parental solicitous responses to children's expressions of discomfort and maternal modeling of their own illness behavior contribute to a greater focus on somatic sensations, leading to illness behaviors in children. This randomized controlled trial will test the effectiveness of an early preventive web-based psychosocial intervention (REACH)[TM] vs. an educational web-based safety comparison condition delivered to parents with IBS to alter parental responses and lead to improved child health and decreased health care costs. Parents with IBS who have children ages 4-7 years are recruited via community-based approaches (e.g., social media advertisements, school electronic distribution, research networks) and health care providers. The target sample is 460 parents randomized to REACH, a web-based social learning and cognitive behavior therapy (SLCBT) intervention or an educational web-based safety comparison condition (EC). Participants will be assessed at baseline, 6-week (immediate post-intervention), 6-month, 12-month, and 18-month follow-up periods (months post-completion of intervention). The primary outcome is change in parental solicitous/protective behaviors. Secondary outcomes include parent risk and protective factors, child health and symptom outcomes, and health care utilization and cost savings. This study adapts a validated, parent-delivered intervention to treat chronic pain in children to a web-based application designed to prevent the development of chronic pain in very young, high-risk children. If successful, this strategy can both prevent adverse sequelae of this condition from developing as well as be widely accessible. Furthermore, the availability of a prevention model for parent training could result in significant short- and long-term health benefits across a broad spectrum of conditions. ClinicalTrials.gov NCT05730491. Registered on February 15, 2023.
Abstract Summary: Scientists are doing a study to see if a special online program can help kids whose parents have tummy troubles (like IBS) avoid getting chronic pain themselves. They think that when parents are very attentive to their kids' pain or show their own pain a lot, it might make kids more aware and worried about their own pain. So, they're testing an online program called REACH to teach parents ways to respond better and help their kids feel better and not go to the doctor as much. They're inviting parents with IBS who have kids between 4 and 7 years old to join the study. The parents will either use the REACH program or just get some safety tips online. The researchers will check on the families over a year and a half to see if the program helps the kids by changing how parents act when their kids are in pain. If it works, this could help lots of kids not get chronic pain and save money on doctor visits. The study's details are on a website called ClinicalTrials.gov, and it started on February 15, 2023.

9(18):.
Abstract: BACKGROUNDAn HIV-1 DNA vaccine composed of 7 highly conserved, structurally important elements (conserved elements, CE) of p24Gag was tested in a phase I randomized, double-blind clinical trial (HVTN 119, NCT03181789) in people without HIV. DNA vaccination of CE prime/CE+p55Gag boost was compared with p55Gag.METHODSTwo groups (n = 25) received 4 DNA vaccinations (CE/CE+p55Gag or p55Gag) by intramuscular injection/electroporation, including IL-12 DNA adjuvant. The placebo group (n = 6) received saline. Participants were followed for safety and tolerability. Immunogenicity was assessed for T cell and antibody responses.RESULTSBoth regimens were safe and generally well tolerated. The p24CE vaccine was immunogenic and significantly boosted by CE+p55Gag (64% CD4+, P = 0.037; 42% CD8+, P = 0.004). CE+p55Gag induced responses to 5 of 7 CE, compared with only 2 CE by p55Gag DNA, with a higher response to CE5 in 30% of individuals (P = 0.006). CE+p55Gag induced significantly higher CD4+ CE T cell breadth (0.68 vs. 0.22 CE; P = 0.029) and a strong trend for overall T cell breadth (1.14 vs. 0.52 CE; P = 0.051). Both groups developed high cellular and humoral responses. p24CE vaccine-induced CD4+ CE T cell responses correlated (P = 0.007) with p24Gag antibody responses.CONCLUSIONThe CE/CE+p55Gag DNA vaccine induced T cell responses to conserved regions in p24Gag, increasing breadth and epitope recognition throughout p55Gag compared with p55Gag DNA. Vaccines focusing immune responses by priming responses to highly conserved regions could be part of a comprehensive HIV vaccine strategy.TRIAL REGISTRATIONClinical Trials.gov NCT03181789FUNDINGHVTN, NIAID/NIH.
Abstract Summary: Scientists did a study (HVTN 119) to see if a new kind of HIV vaccine would be safe and work well in people who don't have HIV. They made a vaccine from special parts of the virus that don't change much and tested it against another vaccine. They gave 50 people the vaccines and 6 people a saltwater shot with no medicine in it. Everyone got shots 4 times with a helper ingredient to make the vaccine work better.
They checked to see if the people's bodies were okay with the vaccine and if their immune systems (the body's defense against germs) reacted by making T cells (fighter cells) and antibodies (germ catchers). Both vaccines were safe, and the new vaccine made the immune system respond better, especially when it was given with the full-length virus part. This means the new vaccine helped the body recognize and prepare to fight HIV better.
This study is important because it shows that vaccines that focus on the parts of HIV that don't change much could help the body fight the virus better. This could be a big step in making a really good HIV vaccine for everyone.

Effects of open-label transdermal nicotine antidepressant augmentation on affective symptoms and executive function in late-life depression.
J Affect Disord.
2024 Oct 1;
362:416-424.
Abstract: Late-life depression (LLD) is characterized by a poor response to antidepressant medications and diminished cognitive performance, particularly in executive functioning. There is currently no accepted pharmacotherapy for LLD that effectively treats both mood and cognitive symptoms. This study investigated whether transdermal nicotine augmentation of standard antidepressant medications benefitted mood and cognitive symptoms in LLD. Nonsmoking participants aged 60 years or older with unremitted LLD on stable SSRI or SNRI medications (N = 29) received transdermal nicotine patches up to a 21 mg daily dose over 12 weeks. Clinical measures assessed depression severity, secondary affective symptoms, and cognitive performance. Nicotine metabolite concentrations were obtained from blood samples. Depression severity significantly decreased over the trial, with a 76 % response rate and 59 % remission rate. Change in depression severity was positively associated with nicotine exposure. Participants also exhibited improvement in self-reported affective symptoms (apathy, insomnia, rumination, and generalized anxiety symptoms), negativity bias, and disability. Executive function test performance significantly improved, specifically in measures of cognitive control, as did subjective cognitive performance. Adverse events were generally mild, with 75 % of the sample tolerating the maximum dose. The current study extends our previous pilot open-label trial in LLD, supporting feasibility and tolerability of transdermal nicotine patches as antidepressant augmentation. Although preliminary, this open-label study supports the potential benefit of transdermal nicotine patches for both mood and cognitive symptoms of LLD. Further research, including definitive randomized, blinded trials, is warranted to confirm these findings and explore long-term risk and benefit. The study was registered with clinicaltrials.gov (NCT04433767).
Abstract Summary: Doctors wanted to see if special patches that give a small amount of nicotine could help older people who feel very sad and have trouble thinking clearly, even when they take medicine for it. They tested these patches on people over 60 who didn't smoke. These people wore the patches for 12 weeks. The doctors checked if they felt less sad and if their thinking got better. They found that most people felt a lot happier and their brains worked better, especially when they had to control their thoughts. The patches didn't cause many problems, and most people were okay with wearing them. This study was just a first step, so more tests are needed to make sure these patches are safe and really work over time.

2024 Oct 1;
31(10):2294-2303.
Abstract: Returning aggregate study results is an important ethical responsibility to promote trust and inform decision making, but the practice of providing results to a lay audience is not widely adopted. Barriers include significant cost and time required to develop lay summaries and scarce infrastructure necessary for returning them to the public. Our study aims to generate, evaluate, and implement ChatGPT 4 lay summaries of scientific abstracts on a national clinical study recruitment platform, ResearchMatch, to facilitate timely and cost-effective return of study results at scale. We engineered prompts to summarize abstracts at a literacy level accessible to the public, prioritizing succinctness, clarity, and practical relevance. Researchers and volunteers assessed ChatGPT-generated lay summaries across five dimensions: accuracy, relevance, accessibility, transparency, and harmfulness. We used precision analysis and adaptive random sampling to determine the optimal number of summaries for evaluation, ensuring high statistical precision. ChatGPT achieved 95.9% (95% CI, 92.1-97.9) accuracy and 96.2% (92.4-98.1) relevance across 192 summary sentences from 33 abstracts based on researcher review. 85.3% (69.9-93.6) of 34 volunteers perceived ChatGPT-generated summaries as more accessible and 73.5% (56.9-85.4) more transparent than the original abstract. None of the summaries were deemed harmful. We expanded ResearchMatch's technical infrastructure to automatically generate and display lay summaries for over 750 published studies that resulted from the platform's recruitment mechanism. Implementing AI-generated lay summaries on ResearchMatch demonstrates the potential of a scalable framework generalizable to broader platforms for enhancing research accessibility and transparency.
Abstract Summary: Scientists believe it's important to share simple summaries of their studies with everyone, not just other scientists. However, making these easy-to-understand summaries takes a lot of time and money, and there isn't always a good way to share them with the public. This study tested if a computer program called ChatGPT could help by making short, clear summaries of complicated science papers. They checked if the summaries were correct, relevant, easy to understand, clear, and not misleading or harmful.
The computer program did a great job! It made accurate and relevant summaries for 33 different science papers. Most of the 34 people who read these summaries found them easier to understand and clearer than the original science papers. They also didn't find anything wrong or harmful in the summaries.
Thanks to this study, a website called ResearchMatch, which helps find people for studies, can now use ChatGPT to automatically create and show these simple summaries for over 750 studies. This means more people can learn about research easily, which can help them trust and make better decisions about science.

Abstract: The objective of this study was to test the feasibility and acceptability of a treatment for weight bullying. Participants who had experienced weight-related bullying and were currently experiencing traumatic stress were recruited and enrolled in a feasibility trial of trauma-focused cognitive behavioral therapy combined with cognitive-behavioral therapy for eating disorders (TF-CBT-WB). Thirty adolescents (aged 11-17) were determined eligible and 28 began treatment (12 weeks). This study demonstrated the treatment feasibility and acceptability of TF-CBT-WB for adolescents with traumatic stress following weight-bullying experiences. Overall retention and treatment satisfaction were good. Within-subjects improvements were observed for intrusion symptoms of traumatic stress, global eating-disorder severity, overvaluation of weight/shape, dissatisfaction with weight/shape, dietary restraint, and depression. Clinically-meaningful improvements were attained for several patient outcomes. Clinically-meaningful decreases in functional impairment were attained by more than half of the participants. Overall, this clinical trial testing TF-CBT-WB for adolescents experiencing traumatic stress following weight-bulling experiences demonstrated therapy feasibility, acceptability, and initial evidence that clinically-meaningful improvements in patient outcomes were feasible. However, some patient outcomes thought to be more central to how the youth viewed the world failed to show improvements, suggesting that additional content related to these constructs might yield greater benefit. This pilot study was registered on clinicaltrials.gov: NCT04587752, Cognitive-Behavioral Therapy for Weight-related Bullying.
Abstract Summary: Scientists did a study to see if a special kind of talking therapy could help kids who felt really bad after being bullied about their weight. They worked with 30 kids between 11 and 17 years old who felt stressed because of the bullying. The therapy lasted for 12 weeks and most kids stuck with it and liked it. After the therapy, the kids felt better about themselves, didn't think about their weight all the time, ate in a healthier way, and weren't as sad. More than half of the kids also did better in their daily lives. But, some ways the kids saw the world didn't change much, so the scientists think adding more to the therapy could help even more. This study shows that this kind of therapy could really help kids who are hurt by weight bullying.

Household Toilet and Sanitation Insecurity is Associated With Urinary Symptoms, Psychosocial Burden, and Compensatory Bladder Behaviors.

Abstract: To investigate whether being "at-risk" for toilet and sanitation insecurity in the United States is associated with urinary symptoms, voiding behaviors, and psychosocial burden. Based on census data, nearly 2 million people in the United States do not have access to adequate plumbing. More may have inconsistent access related to cost, inadequate facilities for the number of people in a home, or declining regional infrastructure. The effects of inadequate access in the United States are poorly characterized. This is a secondary analysis of a community-based sample of adults electronically recruited to complete questionnaires on clinical and sociodemographic information, living situations, home toilets and plumbing, urinary symptoms, compensatory bladder behaviors, and psychosocial burden. Multivariable logistic regression was used to assess for associations between being at-risk for toilet and sanitation insecurity and urinary and psychosocial symptoms. Linear regression was used to assess for association with adopting compensatory bladder behaviors. This sample included 4218 participants, of whom 17% were identified as being at-risk for toilet and sanitation insecurity. Being at-risk for toilet and sanitation insecurity was associated with worse overall urinary symptoms and greater bother from these symptoms, in addition to worse self-assessed mental and physical health, anxiety, stress, depression, and fewer social supports. Finally, those at-risk for toilet and sanitation insecurity were more likely to adopt burdensome and unhealthy compensatory bladder behaviors. As with other social determinants of health, toilet and sanitation insecurity may be an under-appreciated contributor to urinary symptoms, unhealthy toileting behaviors, and psychosocial distress.
Abstract Summary: Scientists did a study to see if people who might not have good toilets or plumbing at home in the United States have problems with going to the bathroom and feeling stressed or sad. They asked 4,218 adults to answer questions about their health, how they live, and their toilets at home. They found that 17% of these people didn't have good access to toilets or plumbing. These people had more trouble with bathroom issues, felt more bothered by these problems, and were not feeling as good mentally and physically. They also felt more anxious, stressed, and depressed, and didn't have as much support from friends or family. Plus, they had to do things that weren't good for them just to manage going to the bathroom. The study shows that not having a good toilet or plumbing can make people feel bad in many ways.

The subcutaneous adipose transcriptome identifies a molecular signature of insulin resistance shared with visceral adipose.

The subcutaneous adipose transcriptome identifies a molecular signature of insulin resistance shared with visceral adipose.
Obesity (Silver Spring).
2024 Aug;
32(8):1526-1540.
Abstract: The objective of this study was to identify the transcriptional landscape of insulin resistance (IR) in subcutaneous adipose tissue (SAT) in humans across the spectrum of obesity. We used SAT RNA sequencing in 220 individuals with metabolic phenotyping. We identified a 35-gene signature with high predictive accuracy for homeostatic model of IR that was expressed across a variety of non-immune cell populations. We observed primarily "protective" IR associations for adipocyte transcripts and "deleterious" associations for macrophage transcripts, as well as a high concordance between SAT and visceral adipose tissue (VAT). Multiple SAT genes exhibited dynamic expression 5 years after weight loss surgery and with insulin stimulation. Using available expression quantitative trait loci in SAT and/or VAT, we demonstrated similar genetic effect sizes of SAT and VAT on type 2 diabetes and BMI. SAT is conventionally viewed as a metabolic buffer for lipid deposition during positive energy balance, whereas VAT is viewed as a dominant contributor to and prime mediator of IR and cardiometabolic disease risk. Our results implicate a dynamic transcriptional architecture of IR that resides in both immune and non-immune populations in SAT and is shared with VAT, nuancing the current VAT-centric concept of IR in humans.
Abstract Summary: Scientists wanted to learn more about how the body's fat cells, especially those just under the skin, are involved in insulin resistance (IR), which is when the body doesn't respond well to insulin and can lead to obesity. They studied the activity of different genes in the fat cells of 220 people. They found a group of 35 genes that can tell if someone has insulin resistance. They noticed that some genes in fat cells help protect against insulin resistance, while others, especially in immune cells, can make it worse. They also found that the fat under the skin and the fat deeper in the belly act similarly when it comes to insulin resistance. After some people had surgery to lose weight, the activity of these genes changed. This study helps us understand that not only the deep belly fat but also the fat just under the skin is important in insulin resistance, which is linked to diabetes and heart disease. This information could help doctors better understand and treat these conditions.

20(8):5617-5628.
Abstract: This study investigated the potential of phosphorylated plasma Tau217 ratio (pTau217R) and plasma amyloid beta (Aβ) 42/Aβ40 in predicting brain amyloid levels measured by positron emission tomography (PET) Centiloid (CL) for Alzheimer's disease (AD) staging and screening. Quantification of plasma pTau217R and Aβ42/Aβ40 employed immunoprecipitation-mass spectrometry. CL prediction models were developed on a cohort of 904 cognitively unimpaired, preclinical and early AD subjects and validated on two independent cohorts. Models integrating pTau217R outperformed Aβ42/Aβ40 alone, predicting amyloid levels up to 89.1 CL. High area under the receiver operating characteristic curve (AUROC) values (89.3% to 94.7%) were observed across a broad CL range (15 to 90). Utilizing pTau217R-based models for low amyloid levels reduced PET scans by 70.5% to 78.6%. pTau217R effectively predicts brain amyloid levels, surpassing cerebrospinal fluid Aβ42/Aβ40's range. Combining it with plasma Aβ42/Aβ40 enhances sensitivity for low amyloid detection, reducing unnecessary PET scans and expanding clinical utility. NCT02956486 (MissionAD1), NCT03036280 (MissionAD2), NCT04468659 (AHEAD3-45), NCT03887455 (ClarityAD) HIGHLIGHTS: Phosphorylated plasma Tau217 ratio (pTau217R) effectively predicts amyloid-PET Centiloid (CL) across a broad spectrum. Integrating pTau217R with Aβ42/Aβ40 extends the CL prediction upper limit to 89.1 CL. Combined model predicts amyloid status with high accuracy, especially in cognitively unimpaired individuals. This model identifies subjects above or below various CL thresholds with high accuracy. pTau217R-based models significantly reduce PET scans by up to 78.6% for screening out individuals with no/low amyloid.
Abstract Summary: Scientists did a study to see if they could use blood tests to guess how much of a certain protein called amyloid is in the brain. This protein can show if someone might get Alzheimer's disease. They used a special machine to measure amyloid in the brain and then tried to predict these measurements using two things in the blood: pTau217R and Aβ42/Aβ40. They tested their ideas on over 900 people with different stages of memory health.
They found that using pTau217R in the blood was really good at guessing the amyloid levels in the brain, even better than using another method that checks the fluid from the spine. When they combined pTau217R with Aβ42/Aβ40, the predictions got even better. This is important because it means that a lot of people might not need to have a big machine scan their brain to check for Alzheimer's disease. Instead, they could just have a simple blood test. This could help doctors find out who needs more testing and who doesn't, making it easier and faster to look after people's brains.

Remote Monitoring App for Endocrine Therapy Adherence Among Patients With Early-Stage Breast Cancer: A Randomized Clinical Trial.
JAMA Netw Open.

7(6):e2417873.
Abstract: Adjuvant endocrine therapy (AET) use among women with early-stage, hormone receptor-positive breast cancer reduces the risk of cancer recurrence, but its adverse symptoms contribute to lower adherence. To test whether remote monitoring of symptoms and treatment adherence with or without tailored text messages improves outcomes among women with breast cancer who are prescribed AET. This nonblinded, randomized clinical trial (RCT) following intention-to-treat principles included English-speaking women with early-stage breast cancer prescribed AET at a large cancer center with 14 clinics across 3 states from November 15, 2018, to June 11, 2021. All participants had a mobile device with a data plan and an email address and were asked to use an electronic pillbox to monitor AET adherence and to complete surveys at enrollment and 1 year. Participants were randomized into 3 groups: (1) an app group, in which participants received instructions for and access to the study adherence and symptom monitoring app for 6 months; (2) an app plus feedback group, in which participants received additional weekly text messages about managing symptoms, adherence, and communication; or (3) an enhanced usual care (EUC) group. App-reported missed doses, increases in symptoms, and occurrence of severe symptoms triggered follow-ups from the oncology team. The primary outcome was 1-year, electronic pillbox-captured AET adherence. Secondary outcomes included symptom management abstracted from the medical record, as well as patient-reported health care utilization, symptom burden, quality of life, physician communication, and self-efficacy for managing symptoms. Among 304 female participants randomized (app group, 98; app plus feedback group, 102; EUC group, 104), the mean (SD) age was 58.6 (10.8) years (median, 60 years; range, 31-83 years), and 60 (19.7%) had an educational level of high school diploma or less. The study completion rate was 87.5% (266 participants). There were no statistically significant differences by treatment group in AET adherence (primary outcome): 76.6% for EUC, 73.4% for the app group (difference vs EUC, -3.3%; 95% CI, -11.4% to 4.9%; P = .43), and 70.9% for the app plus feedback group (difference vs EUC, -5.7%; 95% CI, -13.8% to 2.4%; P = .17). At the 1-year follow-up, app plus feedback participants had fewer total health care encounters (adjusted difference, -1.23; 95% CI, -2.03 to -0.43; P = .003), including high-cost encounters (adjusted difference, -0.40; 95% CI, -0.67 to -0.14; P = .003), and office visits (adjusted difference, -0.82; 95% CI, -1.54 to -0.09; P = .03) over the previous 6 months compared with EUC participants. This RCT found that a remote monitoring app with alerts to the patient's care team and tailored text messages to patients did not improve AET adherence among women with early-stage breast cancer; however, it reduced overall and high-cost health care encounters and office visits without affecting quality of life. ClinicalTrials.gov Identifier: NCT03592771.
Abstract Summary: Doctors want to help women with a certain kind of early breast cancer take their medicine regularly because it can stop the cancer from coming back. But sometimes, the medicine can make them feel bad, and they might not take it as they should. To see if they could help, doctors did a study with 304 women. They gave some women an app to track when they took their medicine and how they felt. Some also got special text messages with advice. Another group just got regular care. They found that the app and texts didn't help women take their medicine more, but those who got texts went to the doctor less and saved money on healthcare without feeling worse. This study shows that while the app and texts didn't help with taking medicine, they did help in other ways.

Effects of canagliflozin on total heart failure events across the kidney function spectrum: Participant-level pooled analysis from the CANVAS Program and CREDENCE trial.
Eur J Heart Fail.
2024 Jun 26;

Abstract: People with type 2 diabetes (T2D) face high risks of heart failure (HF) hospitalizations that are often recurrent, especially as kidney function declines. We examined the effects of canagliflozin on total HF events by baseline kidney function in patients with T2D at high cardiovascular risk and/or with chronic kidney disease. Leveraging pooled participant-level data from the CANVAS programme (n = 10 142) and CREDENCE trial (n = 4401), first and total HF hospitalizations were examined. Cox proportional hazards models were built for the time to first HF hospitalization, and proportional means models based on cumulative mean functions were used for recurrent HF hospitalizations. Treatment effects were evaluated overall as well as within baseline estimated glomerular filtration rate (eGFR) strata (<45, 45-60, and >60 ml/min/1.73 m). HF hospitalizations were independently and blindly adjudicated. Among 14 540 participants with available baseline eGFR values, 672 HF hospitalizations occurred over a median follow-up of 2.5 years. Among participants who experienced a HF hospitalization, 357 had a single event (201 in placebo-treated patients and 156 in canagliflozin-treated patients), 77 had 2 events, and 39 had >2 events. Canagliflozin reduced risk of first HF hospitalization (hazard ratio 0.58, 95% confidence interval [CI] 0.48-0.70) consistently across baseline eGFR strata (p = 0.84). Canagliflozin reduced total HF hospitalizations overall (mean event ratio 0.63, 95% CI 0.54-0.73) and across eGFR subgroups (p = 0.51). Canagliflozin also reduced cardiovascular death and total HF hospitalizations (mean event ratio 0.72, 95% CI 0.65-0.80) and across eGFR subgroups (p = 0.82). The absolute risk reductions were numerically larger, and numbers needed to treat were smaller when evaluating total events versus first events alone. These observed HF benefits were highly consistent across the range of eGFR, with larger absolute benefits in participants who had worse kidney function at baseline. In individuals with T2D at high cardiovascular risk and/or with chronic kidney disease, canagliflozin reduced the total burden of HF hospitalizations, with consistent benefits observed across the kidney function spectrum. ClinicalTrials.gov Identifier: CANVAS (NCT01032629), CANVAS-R (NCT01989754), CREDENCE (NCT02065791).
Abstract Summary: Doctors wanted to see if a medicine called canagliflozin could help people with type 2 diabetes who are at risk of heart problems or have kidney disease. They looked at over 14,000 people to see how often they had to go to the hospital for heart failure. They found that people who took canagliflozin didn't have to go to the hospital as much for heart problems. This was true for people with different levels of kidney health. The medicine helped prevent not just the first time someone went to the hospital, but also if they had to go back again. This is good news because it means that taking canagliflozin might help a lot of people with diabetes stay out of the hospital and have healthier hearts.

Obesity induces PD-1 on macrophages to suppress anti-tumour immunity.

Obesity induces PD-1 on macrophages to suppress anti-tumour immunity.

Abstract: Obesity is a leading risk factor for progression and metastasis of many cancers, yet can in some cases enhance survival and responses to immune checkpoint blockade therapies, including anti-PD-1, which targets PD-1 (encoded by PDCD1), an inhibitory receptor expressed on immune cells. Although obesity promotes chronic inflammation, the role of the immune system in the obesity-cancer connection and immunotherapy remains unclear. It has been shown that in addition to T cells, macrophages can express PD-1. Here we found that obesity selectively induced PD-1 expression on tumour-associated macrophages (TAMs). Type I inflammatory cytokines and molecules linked to obesity, including interferon-γ, tumour necrosis factor, leptin, insulin and palmitate, induced macrophage PD-1 expression in an mTORC1- and glycolysis-dependent manner. PD-1 then provided negative feedback to TAMs that suppressed glycolysis, phagocytosis and T cell stimulatory potential. Conversely, PD-1 blockade increased the level of macrophage glycolysis, which was essential for PD-1 inhibition to augment TAM expression of CD86 and major histocompatibility complex I and II molecules and ability to activate T cells. Myeloid-specific PD-1 deficiency slowed tumour growth, enhanced TAM glycolysis and antigen-presentation capability, and led to increased CD8 T cell activity with a reduced level of markers of exhaustion. These findings show that obesity-associated metabolic signalling and inflammatory cues cause TAMs to induce PD-1 expression, which then drives a TAM-specific feedback mechanism that impairs tumour immune surveillance. This may contribute to increased cancer risk yet improved response to PD-1 immunotherapy in obesity.
Abstract Summary: Scientists are studying how being overweight affects the way the body fights cancer. They found that in overweight people, certain immune cells called macrophages, which help the body fight cancer, act differently. These cells turn on a signal called PD-1 when they're around cancer. This signal usually tells the immune system to slow down, which can make it harder for the body to fight cancer. But, when doctors use special medicines that block PD-1, it helps these immune cells work better. This could be why overweight people sometimes respond well to these medicines. The study helps us understand how being overweight changes the way our immune system works against cancer, and it might help doctors treat cancer better in overweight patients.

Abstract: The relationship between cerebrovascular disease (CVD) and amyloid-β (Aβ) in Alzheimer disease (AD) is understudied. We hypothesized that magnetic resonance imaging (MRI)-based CVD biomarkers, including cerebral microbleeds (CMBs), ischemic infarction, and white matter hyperintensities (WMH), would correlate with Aβ positivity on positron emission tomography (Aβ-PET). We cross-sectionally analyzed data from the Alzheimer's Disease Neuroimaging Initiative (ADNI, N=1,352). Logistic regression was used to calculate odds ratios (ORs), with Aβ-PET positivity as the standard-of-truth. Following adjustment, WMH (OR=1.25) and superficial CMBs (OR=1.45) remained positively associated with Aβ-PET positivity (p<.001). Deep CMBs and infarcts exhibited a varied relationship with Aβ-PET in cognitive subgroups. The combined diagnostic model, which included CVD biomarkers and other accessible measures, significantly predicted Aβ-PET (pseudo-R =.41). The study highlights the translational value of CVD biomarkers in diagnosing AD, and underscores the need for more research on their inclusion in diagnostic criteria.

Abstract Summary: Scientists did a study to see if certain signs of blood vessel problems in the brain can help tell if someone has Alzheimer's disease. They used special brain scans called MRI and PET scans to look for these signs in 1,352 people. They found that two signs, called white matter hyperintensities and cerebral microbleeds, were often seen in people who had Alzheimer's. This means that checking for these signs could help doctors figure out if someone has Alzheimer's. The study shows that it's important to learn more about how these brain blood vessel signs can help in diagnosing Alzheimer's disease.

Abstract: Anhedonia is a transdiagnostic symptom often resistant to treatment. The identification of biomarkers sensitive to anhedonia treatment will aid in the evaluation of novel anhedonia interventions. This is an exploratory analysis of changes in subcortical brain volumes accompanying psychotherapy in a transdiagnostic anhedonic sample using ultra-high field (7-Tesla) MRI. Outpatients with clinically impairing anhedonia (n = 116) received Behavioral Activation Treatment for Anhedonia, a novel psychotherapy, or Mindfulness-Based Cognitive Therapy (ClinicalTrials.gov Identifiers NCT02874534 and NCT04036136). Subcortical brain volumes were estimated via the MultisegPipeline, and regions of interest were the amygdala, caudate nucleus, hippocampus, pallidum, putamen, and thalamus. Bivariate mixed effects models estimated pre-treatment relations between anhedonia severity and subcortical brain volumes, change over time in subcortical brain volumes, and associations between changes in subcortical brain volumes and changes in anhedonia symptoms. As reported previously (Cernasov et al., 2023), both forms of psychotherapy resulted in equivalent and significant reductions in anhedonia symptoms. Pre-treatment anhedonia severity and subcortical brain volumes were not related. No changes in subcortical brain volumes were observed over the course of treatment. Additionally, no relations were observed between changes in subcortical brain volumes and changes in anhedonia severity over the course of treatment. This trial included a modest sample size and did not have a waitlist-control condition or a non-anhedonic comparison group. In this exploratory analysis, psychotherapy for anhedonia was not accompanied by changes in subcortical brain volumes, suggesting that subcortical brain volumes may not be a candidate biomarker sensitive to response to psychotherapy.
Abstract Summary: Scientists did a study to see if therapy could help people who don't feel pleasure, a problem called anhedonia. They used a special brain scanner to look at parts of the brain deep inside the head in 116 people. These people tried two kinds of talking therapies to see if they would start feeling better. The researchers checked if the size of certain brain areas changed with therapy and if these changes were linked to people feeling less anhedonia. They found that even though people felt better after therapy, the sizes of those brain parts didn't change. This means that the size of these brain parts might not be a good way to tell if therapy is working for anhedonia.

Abstract: Diabetes is associated with high risks of premature chronic kidney disease (CKD), cardiovascular diseases, cardiovascular death and impaired quality of life. People with diabetes are more likely to develop kidney impairment, and approximately one in three adults with diabetes have CKD. People with CKD and diabetes experience a substantially higher risk of cardiovascular outcomes. Sodium-glucose co-transporter protein 2 (SGLT2) inhibitors have shown potential effects in preventing kidney and cardiovascular outcomes in people with CKD and diabetes. However, new trials are emerging rapidly, and evidence synthesis is essential to summarising cumulative evidence. This review aimed to assess the benefits and harms of SGLT2 inhibitors for people with CKD and diabetes. We searched the Cochrane Kidney and Transplant Register of Studies up to 17 November 2023 using a search strategy designed by an Information Specialist. Studies in the Register are continually identified through regular searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov. Randomised controlled studies were eligible if they evaluated SGLT2 inhibitors versus placebo, standard care or other glucose-lowering agents in people with CKD and diabetes. CKD includes all stages (from 1 to 5), including dialysis patients. Two authors independently extracted data and assessed the study risk of bias. Treatment estimates were summarised using random effects meta-analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI). Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The primary review outcomes were all-cause death, 3-point and 4-point major adverse cardiovascular events (MACE), fatal or nonfatal myocardial infarction (MI), fatal or nonfatal stroke, and kidney failure. Fifty-three studies randomising 65,241 people with CKD and diabetes were included. SGLT2 inhibitors with or without other background treatments were compared to placebo, standard care, sulfonylurea, dipeptidyl peptidase-4 (DPP-4) inhibitors, or insulin. In the majority of domains, the risks of bias in the included studies were low or unclear. No studies evaluated the treatment in children or in people treated with dialysis. No studies compared SGLT2 inhibitors with glucagon-like peptide-1 receptor agonists or tirzepatide. Compared to placebo, SGLT2 inhibitors decreased the risk of all-cause death (20 studies, 44,397 participants: RR 0.85, 95% CI 0.78 to 0.94; I = 0%; high certainty) and cardiovascular death (16 studies, 43,792 participants: RR 0.83, 95% CI 0.74 to 0.93; I = 29%; high certainty). Compared to placebo, SGLT2 inhibitors probably make little or no difference to the risk of fatal or nonfatal MI (2 studies, 13,726 participants: RR 0.95, 95% CI 0.80 to 1.14; I = 24%; moderate certainty), and fatal or nonfatal stroke (2 studies, 13,726 participants: RR 1.07, 95% CI 0.88 to 1.30; I = 0%; moderate certainty). Compared to placebo, SGLT2 inhibitors probably decrease 3-point MACE (7 studies, 38,320 participants: RR 0.89, 95% CI 0.81 to 0.98; I = 46%; moderate certainty), and 4-point MACE (4 studies, 23,539 participants: RR 0.82, 95% CI 0.70 to 0.96; I = 77%; moderate certainty), and decrease hospital admission due to heart failure (6 studies, 28,339 participants: RR 0.70, 95% CI 0.62 to 0.79; I = 17%; high certainty). Compared to placebo, SGLT2 inhibitors may decrease creatinine clearance (1 study, 132 participants: MD -2.63 mL/min, 95% CI -5.19 to -0.07; low certainty) and probably decrease the doubling of serum creatinine (2 studies, 12,647 participants: RR 0.70, 95% CI 0.56 to 0.89; I = 53%; moderate certainty). SGLT2 inhibitors decrease the risk of kidney failure (6 studies, 11,232 participants: RR 0.70, 95% CI 0.62 to 0.79; I = 0%; high certainty), and kidney composite outcomes (generally reported as kidney failure, kidney death with or without ≥ 40% decrease in estimated glomerular filtration rate (eGFR)) (7 studies, 36,380 participants: RR 0.68, 95% CI 0.59 to 0.78; I = 25%; high certainty) compared to placebo. Compared to placebo, SGLT2 inhibitors incur less hypoglycaemia (16 studies, 28,322 participants: RR 0.93, 95% CI 0.89 to 0.98; I = 0%; high certainty), and hypoglycaemia requiring third-party assistance (14 studies, 26,478 participants: RR 0.75, 95% CI 0.65 to 0.88; I = 0%; high certainty), and probably decrease the withdrawal from treatment due to adverse events (15 studies, 16,622 participants: RR 0.94, 95% CI 0.82 to 1.08; I = 16%; moderate certainty). The effects of SGLT2 inhibitors on eGFR, amputation and fracture were uncertain. No studies evaluated the effects of treatment on fatigue, life participation, or lactic acidosis. The effects of SGLT2 inhibitors compared to standard care alone, sulfonylurea, DPP-4 inhibitors, or insulin were uncertain. SGLT2 inhibitors alone or added to standard care decrease all-cause death, cardiovascular death, and kidney failure and probably decrease major cardiovascular events while incurring less hypoglycaemia compared to placebo in people with CKD and diabetes.
Abstract Summary: Scientists did a big study to see if a special medicine called SGLT2 inhibitors can help people with diabetes who also have kidney problems. Diabetes can make it more likely for someone to get sick with heart or kidney diseases. The researchers looked at information from many different studies that included over 65,000 people. They found that this medicine can lower the chance of dying from any cause or from heart problems. It also helps to prevent serious heart events and keeps people from going to the hospital for heart failure. Plus, it's good for the kidneys and doesn't cause low blood sugar as much as some other treatments. This is really important because it means this medicine could help lots of people with diabetes and kidney disease stay healthier.

Abstract: Acute traumatic stress symptoms may develop in people who have been exposed to a traumatic event. Although they are usually self-limiting in time, some people develop post-traumatic stress disorder (PTSD), a severe and debilitating condition. Pharmacological interventions have been proposed for acute symptoms to act as an indicated prevention measure for PTSD development. As many individuals will spontaneously remit, these interventions should balance efficacy and tolerability. To assess the efficacy and acceptability of early pharmacological interventions for prevention of PTSD in adults experiencing acute traumatic stress symptoms. We searched the Cochrane Common Mental Disorders Controlled Trial Register (CCMDCTR), CENTRAL, MEDLINE, Embase and two other databases. We checked the reference lists of all included studies and relevant systematic reviews. The search was last updated on 23 January 2023. We included randomised controlled trials on adults exposed to any kind of traumatic event and presenting acute traumatic stress symptoms, without restriction on their severity. We considered comparisons of any medication with placebo, or with another medication. We excluded trials that investigated medications as an augmentation to psychotherapy. We used standard Cochrane methodological procedures. Using a random-effects model, we analysed dichotomous data as risk ratios (RR) and calculated the number needed to treat for an additional beneficial/harmful outcome (NNTB/NNTH). We analysed continuous data as mean differences (MD) or standardised mean differences (SMD). Our primary outcomes were PTSD severity and dropouts due to adverse events. Secondary outcomes included PTSD rate, functional disability and quality of life. We included eight studies that considered four interventions (escitalopram, hydrocortisone, intranasal oxytocin, temazepam) and involved a total of 779 participants. The largest trial contributed 353 participants and the next largest, 120 and 118 participants respectively. The trials enrolled participants admitted to trauma centres or emergency departments. The risk of bias in the included studies was generally low except for attrition rate, which we rated as high-risk. We could meta-analyse data for two comparisons: escitalopram versus placebo (but limited to secondary outcomes) and hydrocortisone versus placebo. One study compared escitalopram to placebo at our primary time point of three months after the traumatic event. There was inconclusive evidence of any difference in terms of PTSD severity (mean difference (MD) on the Clinician-Administered PTSD Scale (CAPS, score range 0 to 136) -11.35, 95% confidence interval (CI) -24.56 to 1.86; 1 study, 23 participants; very low-certainty evidence), dropouts due to adverse events (no participant left the study early due to adverse events; 1 study, 31 participants; very low-certainty evidence) and PTSD rates (RR 0.59, 95% CI 0.03 to 13.08; NNTB 37, 95% CI NNTB 15 to NNTH 1; 1 study, 23 participants; very low-certainty evidence). The study did not assess functional disability or quality of life. Three studies compared hydrocortisone to placebo at our primary time point of three months after the traumatic event. We found inconclusive evidence on whether hydrocortisone was more effective in reducing the severity of PTSD symptoms compared to placebo (MD on CAPS -7.53, 95% CI -25.20 to 10.13; I = 85%; 3 studies, 136 participants; very low-certainty evidence) and whether it reduced the risk of developing PTSD (RR 0.47, 95% CI 0.09 to 2.38; NNTB 14, 95% CI NNTB 8 to NNTH 5; I = 36%; 3 studies, 136 participants; very low-certainty evidence). Evidence on the risk of dropping out due to adverse events is inconclusive (RR 3.19, 95% CI 0.13 to 75.43; 2 studies, 182 participants; low-certainty evidence) and it is unclear whether hydrocortisone might improve quality of life (MD on the SF-36 (score range 0 to 136, higher is better) 19.70, 95% CI -1.10 to 40.50; 1 study, 43 participants; very low-certainty evidence). No study assessed functional disability. This review provides uncertain evidence regarding the use of escitalopram, hydrocortisone, intranasal oxytocin and temazepam for people with acute stress symptoms. It is therefore unclear whether these pharmacological interventions exert a positive or negative effect in this population. It is important to note that acute traumatic stress symptoms are often limited in time, and that the lack of data prevents the careful assessment of expected benefits against side effects that is therefore required. To yield stronger conclusions regarding both positive and negative outcomes, larger sample sizes are required. A common operational framework of criteria for inclusion and baseline assessment might help in better understanding who, if anyone, benefits from an intervention. As symptom severity alone does not provide the full picture of the impact of exposure to trauma, assessment of quality of life and functional impairment would provide a more comprehensive picture of the effects of the interventions. The assessment and reporting of side effects may facilitate a more comprehensive understanding of tolerability.
Abstract Summary: Scientists did a study to see if taking medicine right after a scary event can help stop a serious problem called PTSD. They looked at different medicines to see if they work and if they're safe. They checked a lot of information and studies with 779 people in them. Some people got a sugar pill (placebo) and some got real medicine. They wanted to know if the medicine could make people feel less scared or stressed later on, and if it could help them live their lives better without making them feel sick or worse.
They found out that they can't be sure if the medicines really help or not. The results weren't clear because there weren't enough people in the studies, and they didn't all measure things the same way. They also didn't look at how the medicines might affect how people live their day-to-day lives. The scientists say they need to do more research with more people and check on more things to really understand if these medicines are good for people who have been through something really scary.

Circ Genom Precis Med.
2024 Jun;
17(3):e004398.
Abstract: Omics refers to the measurement and analysis of the totality of molecules or biological processes involved within an organism. Examples of omics data include genomics, transcriptomics, epigenomics, proteomics, metabolomics, and more. In this review, we present the available literature reporting omics data on heart failure that can inform the development of novel treatments or innovative treatment strategies for this disease. This includes polygenic risk scores to improve prediction of genomic data and the potential of multiomics to more efficiently identify potential treatment targets for further study. We also discuss the limitations of omic analyses and the barriers that must be overcome to maximize the utility of these types of studies. Finally, we address the current state of the field and future opportunities for using multiomics to better personalize heart failure treatment strategies.
Abstract Summary: I'm sorry, but I can't access external websites like ClinicalTrials.gov to look up specific studies or unique identifiers like NCT01960946. However, if you provide me with the abstract text, I'd be happy to help summarize it for you!

Ambulatory Blood Pressure in Patients With Rheumatoid Arthritis: Association With Immune Activation.
J Rheumatol.

51(9):870-876.
Abstract: The prevalence of hypertension, a major cardiovascular risk factor, is increased in patients with rheumatoid arthritis (RA) and may be driven by immune activation. The purpose of this study was to determine if ambulatory 24-hour blood pressure (BP) is elevated in RA vs control participants and whether it is associated with immune activation. We conducted a cross-sectional study of 46 patients with RA and 23 control participants. Participants wore an ambulatory BP monitor that obtained diurnal BP every 15-30 minutes and nocturnal BP every 30 minutes. Inflammatory mediators in plasma were measured using an inflammation proteomics panel. Differences in BP measurements were assessed by Mann-Whitney test, and association with inflammatory mediators was assessed by Spearman correlation. Patients with RA and control participants had similar office BP, but median ambulatory systolic BP (SBP) measurements (24-hour [RA 121 mmHg vs control 116 mmHg; = 0.01], diurnal [RA 128 mmHg vs control 120 mmHg; = 0.003], and nocturnal [RA 112 mmHg vs control 103 mmHg; = 0.002]) were higher in patients with RA. Patients with RA also had higher nocturnal diastolic BP (DBP; RA 63 mmHg vs control 57 mmHg; = 0.02), but other DBP measurements were similar. Nocturnal BP dipping was less in patients with RA (12%) compared to control participants (16%; = 0.02). In patients with RA, higher 24-hour and nocturnal SBPs and less nocturnal dipping were strongly correlated with a wide range of inflammatory mediators. Despite similar office measurements, 24-hour and nocturnal SBP measurements were higher in patients with RA than in control participants and were strongly associated with inflammation.
Abstract Summary: Doctors wanted to see if people with rheumatoid arthritis (RA) have higher blood pressure (BP) over a day and if it's linked to their body's inflammation. They had 46 people with RA and 23 people without it wear a BP monitor for 24 hours. The monitor checked their BP during the day and night. They also tested their blood for signs of inflammation.
They found that even though their BP at the doctor's office was the same, people with RA had higher BP when measured over the whole day and night. Their BP didn't go down as much as it should when they slept. This higher BP and smaller nighttime dip were connected to more inflammation in their bodies.
This study is important because it shows that people with RA might have higher BP that isn't caught at the doctor's office, and it could be because of inflammation. This could help doctors better watch and treat BP in people with RA.

Impact of financial compensation on enrollment and participation in a remote, mobile-app based research study.
J Clin Transl Sci.
2024;
8(1):e75.
Abstract: There is no consensus on how to determine appropriate financial compensation for research recruitment. Selecting incentive amounts that are reasonable and respectful, without undue inducement, remains challenging. Previously, we demonstrated that incentive amount significantly impacts participants' willingness to complete various hypothetical research activities. Here we further explore this relationship in a mock decentralized study. Adult ResearchMatch volunteers were invited to join a prospective study where interested individuals were given an opportunity to view details for a study along with participation requirements, then offered a randomly generated compensation amount between $0 and $50 to enroll and participate. Individuals agreeing to participate were then asked to complete tasks using a remote mobile application (MyCap), for two weeks. Tasks included a weekly survey, a daily gratitude journal and daily phone tapping task. Willingness to participate was 85% across all incentive levels but not significantly impacted by amount. Task completion appeared to increase as a function of compensation until a plateau at $25. While participants described the study as low burden and reported that compensation was moderately important to their decision to join, only 31% completed all study tasks. While offering compensation in this study did not have a strong effect on enrollment rate, this work provides insight into participant motivation when joining and participating in studies employing mobile applications.
Abstract Summary: Scientists are trying to figure out the best way to pay people who join research studies. They want to pay enough to be fair, but not so much that people join just for the money. In a pretend study, grown-ups were asked to join a research project using their phones. They could get paid between $0 and $50. They had to answer questions, write about things they were thankful for every day, and do a tapping task on their phone for two weeks. Most people said yes to joining, no matter how much money was offered. But, people did more tasks when they were paid more, up to $25. After that, paying more didn't make a difference. Even though the study was easy and people said the money mattered a bit, only about 1 in 3 did all the tasks. This study helps us understand why people might join and stay in studies that use phone apps.

Amplification of positivity for depression and anxiety: Neural prediction of treatment response.

Abstract: Psychosocial treatments targeting the positive valence system (PVS) in depression and anxiety demonstrate efficacy in enhancing positive affect (PA), but response to treatment varies. We examined whether individual differences in neural activation to positive and negative valence incentive cues underlies differences in benefitting from a PVS-targeted treatment. Individuals with clinically elevated depression and/or anxiety (N = 88, ages 18 to 55) participated in one of two randomized, waitlist-controlled trials of Amplification of Positivity (AMP; NCT02330627, NCT03196544), a cognitive and behavioral intervention targeting the PVS. Participants completed a monetary incentive delay (MID) task during fMRI acquisition at baseline measuring neural activation to the possibility of gaining or losing money. Change in PA from before to after treatment was assessed using the Positive and Negative Affect Schedule. No significant associations were observed between baseline neural activation during gain anticipation and AMP-related changes in PA in regions of interest (striatum and insula) or whole-brain analyses. However, higher baseline striatal and insula activation during loss anticipation was associated with greater increases in PA post-AMP. This study provides preliminary evidence suggesting neural reactivity to negative valence cues may inform who stands to benefit most from treatments targeting the PVS.
Abstract Summary: Scientists did a study to see if a special kind of therapy that helps people focus on good feelings can make people with sadness or worry feel happier. They worked with 88 people between 18 and 55 years old who felt very sad or worried. These people tried a therapy called Amplification of Positivity (AMP) and played a game where they could win or lose money while their brain activity was watched with a special machine. The researchers wanted to see if the way people's brains reacted to the chance of winning or losing money before the therapy could tell us who would feel happier after the therapy. They found that people whose brains were more active when they might lose money felt happier after the therapy. This study helps us understand that how our brains react to possibly losing something might help us know who will feel better with this kind of therapy.

181:111679.
Abstract: The purpose of this study was to test the preliminary effectiveness of a cognitive behavioral therapy intervention (Fear Reduction Efficacy Evaluation [FREE]) designed to reduce fear of hypoglycemia in young adults with type 1 diabetes. The primary outcome was fear of hypoglycemia, secondary outcomes were A1C, and glycemic variability. A randomized clinical trial was used to test an 8-week intervention (FREE) compared to an attention control (diabetes education) in 50 young adults with type 1 diabetes who experienced fear of hypoglycemia at baseline. All participants wore a continuous glucose monitor for the 8-week study period. Self-reported fear of hypoglycemia point-of-care A1C testing, continuous glucose monitor-derived glucose variability were measured at baseline, Week 8, and Week 12 (post-program). Compared to controls, those participating in the FREE intervention experienced a reduction in fear of hypoglycemia (SMD B = -8.52, p = 0.021), change in A1C (SMD B = 0.04, p = 0.841) and glycemic variability (glucose standard deviation SMD B = -2.5, p = 0.545) by the end of the intervention. This represented an 8.52% greater reduction in fear of hypoglycemia. A cognitive behavioral therapy intervention (FREE) resulted in improvements in fear of hypoglycemia. govNCT03549104.
Abstract Summary: Scientists did a study to see if a special program could help young people with type 1 diabetes feel less scared of their blood sugar dropping too low, which is called hypoglycemia. They had 50 young people try either this new program, called FREE, or a regular diabetes class for 8 weeks. They wore devices to check their blood sugar all the time. The researchers found that the kids who did the FREE program were less scared of low blood sugar than the ones who just learned about diabetes. Even though their blood sugar levels and how much these levels changed didn't improve a lot, feeling less scared is a good thing. This study shows that the FREE program might help young people with diabetes worry less about their blood sugar.

Can strength training or tai ji quan training reduce frailty in postmenopausal women treated with chemotherapy? A secondary data analysis of the GET FIT trial.
J Cancer Surviv.
2024 Aug;
18(4):1179-1189.
Abstract: To determine whether strength training or tai ji quan can reduce frailty in older, postmenopausal women treated with chemotherapy for cancer. We conducted a secondary data analysis from a 3-arm, single-blind, randomized controlled trial where older (50-75 years), postmenopausal women cancer survivors were randomized to supervised group exercise programs: tai ji quan, strength training, or stretching control for 6 months. We assessed frailty using a 4-criteria model consisting of weakness, fatigue, inactivity, and slowness. Using logistic regression, we determined whether the frailty phenotype (pre-frailty or frailty) decreased post-intervention, how many and which frailty criteria decreased, and what characteristics identified women most likely to reduce frailty. Data from 386 women who completed baseline and 6-month testing were used (mean age of 62.0 ± 6.4 years). The odds of reducing overall frailty over 6 months were significantly higher in the strength training group compared to controls (OR [95%CI] 1.86 [1.09, 3.17]) but not for tai ji quan (1.44 [0.84, 2.50]). Both strength training (OR 1.99 [1.10, 3.65]) and tai ji quan (OR 2.10 [1.16, 3.84]) led to significantly higher odds of reducing ≥ 1 frailty criterion compared to controls. Strength training led to a three-fold reduction in inactivity (p < 0.01) and tai ji quan to a two-fold reduction in fatigue (p = 0.08) versus control. Higher baseline BMI, comorbidity score, and frailty status characterized women were more likely to reduce frailty than other women. Strength training appears superior to tai ji quan and stretching with respect to reducing overall frailty phenotype among postmenopausal women treated with chemotherapy for cancer, but tai ji quan favorably reduced the number of frailty criteria. ClinicalTrials.gov identifier: GET FIT was registered as a clinical trial in clinicaltrials.gov: NCT01635413. Supervised, group exercise training that emphasizes strength training and/or tai ji quan may help combat accelerated aging and reduce frailty after cancer treatment.
Abstract Summary: Scientists wanted to see if certain exercises could help older women who had cancer treatments feel stronger and less tired. They had women between 50 and 75 years old do different exercises like tai chi, strength training, or stretching for six months. They checked to see if the women felt less weak, tired, slow, or inactive after doing these exercises. They found that the women who did strength training were more likely to feel less frail compared to those who just stretched. Tai chi also helped, especially with making the women feel less tired. The study suggests that exercises focusing on building strength or doing tai chi can help older women who had cancer treatments feel better and more active.

Racial and ethnic differences in plasma biomarker eligibility for a preclinical Alzheimer's disease trial.
Alzheimers Dement.
2024 Jun;
20(6):3827-3838.
Abstract: In trials of amyloid-lowering drugs for Alzheimer's disease (AD), differential eligibility may contribute to under-inclusion of racial and ethnic underrepresented groups. We examined plasma amyloid beta 42/40 and positron emission tomography (PET) amyloid eligibility for the ongoing AHEAD Study preclinical AD program (NCT04468659). Univariate logistic regression models were used to examine group differences in plasma and PET amyloid screening eligibility. Of 4905 participants screened at time of analysis, 1724 were plasma eligible to continue in screening: 13.3% Hispanic Black, 24.7% Hispanic White, 20.8% non-Hispanic (NH) Asian, 24.7% NH Black, and 38.9% NH White. Plasma eligibility differed across groups in models controlling for covariates (odds ratio from 1.9 to 4.0 compared to the NH White reference group, P < 0.001). Among plasma eligible participants, PET eligibility did not differ by group. These results suggest that prevalence of brain amyloid pathology differed, but that eligibility based on plasma was equally effective across racial and ethnic group members. Plasma amyloid eligibility is lower in underrepresented racial and ethnic groups. In plasma eligible adults, positron emission tomography eligibility rates are similar across race and ethnicity. Plasma biomarker tests may be similarly effective across racial and ethnic groups.
Abstract Summary: Scientists are studying new medicines that might help with Alzheimer's disease, a sickness that affects the brain. They want to make sure that people from all different backgrounds can join in these studies. They looked at two ways to test if someone can be in the study: a blood test and a special brain scan called PET. They tested 4,905 people and found that the number of people who could join the study after the blood test was different for different racial and ethnic groups. But, once people passed the blood test, the brain scan showed that everyone, no matter their background, had the same chance to join the study. This means that the blood test works well for everyone, but it seems like not as many people from certain groups have the signs of Alzheimer's that the study is looking for. This information can help make sure that everyone has a fair chance to be part of research on new Alzheimer's medicines.

44(2):133-140.
Abstract: Anxiety symptoms in major depressive disorder (MDD) are frequent, and they decrease response to antidepressant treatment (ADT), and affect patient functioning. This post hoc analysis examined the efficacy of adjunctive brexpiprazole on individual depressive symptoms and functioning in patients with MDD with anxious distress. Data were included from three 6-week, randomized, double-blind, placebo-controlled studies of adjunctive brexpiprazole in patients with MDD and inadequate response to ADTs (ClinicalTrials.gov identifiers: NCT01360645, NCT01360632, NCT02196506). Patients were stratified using proxy criteria for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, anxious distress. Changes in Montgomery-Åsberg Depression Rating Scale item scores and Sheehan Disability Scale mean score from baseline to week 6 were determined for ADT + brexpiprazole (2 and 2-3 mg) versus ADT + placebo. At baseline, 450 of 746 patients (60.3%, 2 mg analysis) and 670 of 1162 patients (57.7%, 2-3 mg analysis) had anxious distress. In patients with anxious distress, ADT + brexpiprazole 2 mg or 2 to 3 mg showed greater improvements than ADT + placebo (P < 0.05) on the Montgomery-Åsberg Depression Rating Scale items of apparent sadness, reported sadness, inner tension, reduced sleep, reduced appetite, lassitude, inability to feel, and pessimistic thoughts (Cohen d effect sizes, 0.18-0.44), and on Sheehan Disability Scale mean score (effect sizes, 0.21-0.23). Adjunctive brexpiprazole is efficacious in reducing core depressive symptoms, sleep, and appetite, as well as improving functioning, in patients with MDD and anxious distress who have inadequate response to ADTs.
Abstract Summary: Scientists did a study to see if a medicine called brexpiprazole could help people who feel very sad and worried all the time, a condition known as major depressive disorder with anxious distress. These people didn't feel better after taking usual depression medicines. The study included 746 patients, and they were given either brexpiprazole or a pretend pill without any medicine (placebo) along with their regular depression medicine for 6 weeks. They found that the people who took brexpiprazole felt less sad, less worried, slept better, ate better, and could do their daily activities better than those who took the pretend pill. This means that adding brexpiprazole might help people with depression and anxiety who don't get better with just the usual medicines.

Abstract: Circulating concentrations of vascular endothelial growth factor (VEGF) family members may be abnormally elevated in type 2 diabetes (T2D). The roles of placental growth factor (PlGF), soluble fms-like tyrosine kinase-1 (sFLT-1), and VEGF-A in cardio-renal complications of T2D are not established. The 2602 individuals with diabetic kidney disease (DKD) from the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation trial were randomized to receive canagliflozin or placebo and followed for incident cardio-renal outcomes. PlGF, sFLT-1, and VEGF-A were measured at baseline, year 1, and year 3. Primary outcome was a composite of end-stage kidney disease, doubling of the serum creatinine, or renal/cardiovascular death. Cox proportional hazard regression was used to investigate the association between biomarkers with adverse clinical events. At baseline, individuals with higher PlGF levels had more prevalent cardiovascular disease compared to those with lower values. Treatment with canagliflozin did not meaningfully change PlGF, sFLT-1, and VEGF-A concentrations at years 1 and 3. In a multivariable model, 1 unit increases in baseline log PlGF (hazard ratio [HR]: 1.76, 95% confidence interval [CI]: 1.23, 2.54, P-value = .002), sFLT-1 (HR: 3.34, [95% CI: 1.71, 6.52], P-value < .001), and PlGF/sFLT-1 ratio (HR: 4.83, [95% CI: 0.86, 27.01], P-value = .07) were associated with primary composite outcome, while 1 unit increase in log VEGF-A did not increase the risk of primary outcome (HR: 0.96 [95% CI: 0.81, 1.07]). Change by 1 year of each biomarker was also assessed: HR (95% CI) of primary composite outcome was 2.45 (1.70, 3.54) for 1 unit increase in 1-year concentration of log PlGF, 4.19 (2.18, 8.03) for 1 unit increase in 1-year concentration of log sFLT-1, and 21.08 (3.79, 117.4) for 1 unit increase in 1-year concentration of log PlGF/sFLT-1. Increase in 1-year concentrations of log VEGF-A was not associated with primary composite outcome (HR: 1.08, [95% CI: 0.93, 1.24], P-value = .30). People with T2D and DKD with elevated levels of PlGF, sFLT-1, and PlGF/sFLT-1 ratio were at a higher risk for cardiorenal events. Canagliflozin did not meaningfully decrease concentrations of PlGF, sFLT-1, and VEGF-A. CREDENCE, https://clinicaltrials.gov/ct2/show/NCT02065791.
Abstract Summary: Scientists did a study to see if certain blood markers are linked to heart and kidney problems in people with type 2 diabetes and kidney disease. They checked the levels of these markers in 2602 people who were either given a diabetes medicine called canagliflozin or a placebo. They found that people with higher levels of certain markers had a greater chance of having heart and kidney issues. The medicine didn't really change the levels of these markers. This research helps us understand that testing for these markers could tell doctors who is at higher risk for serious health problems.

Pharmacogenetic Factors Influence Escitalopram Pharmacokinetics and Adverse Events in Youth with a Family History of Bipolar Disorder: A Preliminary Study.
J Child Adolesc Psychopharmacol.
2024 Feb;
34(1):42-51.
Abstract: Escitalopram is an effective and generally well-tolerated antidepressant, but children of parents with bipolar disorder (BD) may be at increased risk for adverse events associated with antidepressants, including increased irritability, restlessness, impulsivity, and manic symptoms. This risk may be influenced by polymorphisms in genes encoding cytochrome P450 enzymes ( or ), the serotonin transporter (), and the serotonin receptor 2A subtype (). We explored whether gene-drug interactions influence the emergence of adverse events in depressed and/or anxious youth with a family history of BD. Children and adolescents aged 12-17 years with a first-degree relative with bipolar I disorder were treated with escitalopram and monitored for adverse effects, underwent pharmacogenetic testing, and provided serum escitalopram levels. Emergence of adverse events was determined by study clinicians, and symptoms were tracked using the Treatment-Emergent Activation and Suicidality Assessment Profile (TEASAP) and Pediatric Adverse Events Rating Scale. Clinical Pharmacogenetics Implementation Consortium guidelines were used to determine CYP2C19 and CYP2D6 phenotypes. Slower CYP2C19 metabolizers had greater dose-normalized 24-hour area under the curve (AUC; = 0.025), trough concentrations (C; = 0.013), and elimination half-lives (t; < 0.001). CYP2D6 phenotype was not significantly associated with any pharmacokinetic parameter. Slower CYP2D6 metabolizers had increased TEASAP akathisia ( = 0.015) scores. and genotypes were associated with increased TEASAP "self-injury, suicidality, and harm to others" subscale scores ( = 0.017). Escitalopram maximum concentration, AUC, CYP2C19 phenotype, and genotype were not associated with adverse events. CYP2C19 phenotype influences escitalopram pharmacokinetics whereas CYP2D6 phenotype does not. Slower CYP2D6 metabolism was associated with increased akathisia, and or genotypes were associated with increased risk of self-harm or harm to others. Larger cohorts are needed to identify associations between genetic test results and antidepressant-associated adverse events. ClinicalTrials.gov identifier: NCT02553161.
Abstract Summary: Scientists did a study to see if a medicine called escitalopram, which helps people feel less sad, might not work well for kids whose parents have a type of mood problem called bipolar disorder. They wanted to know if certain differences in the kids' genes could make them feel more restless or even hurt themselves when taking this medicine. They gave the medicine to kids and teenagers between 12 and 17 years old who had a parent with bipolar disorder and watched for any bad reactions. They also checked their genes and how much medicine was in their blood.
They found that kids who broke down the medicine slowly in their bodies had more of it in their blood for longer and were more likely to feel really restless. Also, certain gene differences made it more likely for kids to hurt themselves or others. But they need to study more kids to be sure about these results. This research helps us understand that sometimes, the way our bodies handle medicine and our genes can change how we react to the medicine.

2(2):CD013591.
Abstract: Obesity is considered to be a risk factor for various diseases, and its incidence has tripled worldwide since 1975. In addition to potentially being at risk for adverse health outcomes, people with overweight or obesity are often stigmatised. Behaviour change interventions are increasingly delivered as mobile health (m-health) interventions, using smartphone apps and wearables. They are believed to support healthy behaviours at the individual level in a low-threshold manner. To assess the effects of integrated smartphone applications for adolescents and adults with overweight or obesity. We searched CENTRAL, MEDLINE, PsycINFO, CINAHL, and LILACS, as well as the trials registers ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform on 2 October 2023 (date of last search for all databases). We placed no restrictions on the language of publication. Participants were adolescents and adults with overweight or obesity. Eligible interventions were integrated smartphone apps using at least two behaviour change techniques. The intervention could target physical activity, cardiorespiratory fitness, weight loss, healthy diet, or self-efficacy. Comparators included no or minimal intervention (NMI), a different smartphone app, personal coaching, or usual care. Eligible studies were randomised controlled trials of any duration with a follow-up of at least three months. We used standard Cochrane methodology and the RoB 2 tool. Important outcomes were physical activity, body mass index (BMI) and weight, health-related quality of life, self-efficacy, well-being, change in dietary behaviour, and adverse events. We focused on presenting studies with medium- (6 to < 12 months) and long-term (≥ 12 months) outcomes in our summary of findings table, following recommendations in the core outcome set for behavioural weight management interventions. We included 18 studies with 2703 participants. Interventions lasted from 2 to 24 months. The mean BMI in adults ranged from 27 to 50, and the median BMI z-score in adolescents ranged from 2.2 to 2.5. Smartphone app versus no or minimal intervention Thirteen studies compared a smartphone app versus NMI in adults; no studies were available for adolescents. The comparator comprised minimal health advice, handouts, food diaries, smartphone apps unrelated to weight loss, and waiting list. Measures of physical activity: at 12 months' follow-up, a smartphone app compared to NMI probably reduces moderate to vigorous physical activity (MVPA) slightly (mean difference (MD) -28.9 min/week (95% confidence interval (CI) -85.9 to 28; 1 study, 650 participants; moderate-certainty evidence)). We are very uncertain about the results of estimated energy expenditure and cardiorespiratory fitness at eight months' follow-up. A smartphone app compared with NMI probably results in little to no difference in changes in total activity time at 12 months' follow-up and leisure time physical activity at 24 months' follow-up. Anthropometric measures: a smartphone app compared with NMI may reduce BMI (MD of BMI change -2.6 kg/m, 95% CI -6 to 0.8; 2 studies, 146 participants; very low-certainty evidence) at six to eight months' follow-up, but the evidence is very uncertain. At 12 months' follow-up, a smartphone app probably resulted in little to no difference in BMI change (MD -0.1 kg/m, 95% CI -0.4 to 0.3; 1 study; 650 participants; moderate-certainty evidence). A smartphone app compared with NMI may result in little to no difference in body weight change (MD -2.5 kg, 95% CI -6.8 to 1.7; 3 studies, 1044 participants; low-certainty evidence) at 12 months' follow-up. At 24 months' follow-up, a smartphone app probably resulted in little to no difference in body weight change (MD 0.7 kg, 95% CI -1.2 to 2.6; 1 study, 245 participants; moderate-certainty evidence). A smartphone app compared with NMI may result in little to no difference in self-efficacy for a physical activity score at eight months' follow-up, but the results are very uncertain. A smartphone app probably results in little to no difference in quality of life and well-being at 12 months (moderate-certainty evidence) and in little to no difference in various measures used to inform dietary behaviour at 12 and 24 months' follow-up. We are very uncertain about adverse events, which were only reported narratively in two studies (very low-certainty evidence). Smartphone app versus another smartphone app Two studies compared different versions of the same app in adults, showing no or minimal differences in outcomes. One study in adults compared two different apps (calorie counting versus ketogenic diet) and suggested a slight reduction in body weight at six months in favour of the ketogenic diet app. No studies were available for adolescents. Smartphone app versus personal coaching Only one study compared a smartphone app with personal coaching in adults, presenting data at three months. Two studies compared these interventions in adolescents. A smartphone app resulted in little to no difference in BMI z-score compared to personal coaching at six months' follow-up (MD 0, 95% CI -0.2 to 0.2; 1 study; 107 participants). Smartphone app versus usual care Only one study compared an app with usual care in adults but only reported data at three months on participant satisfaction. No studies were available for adolescents. We identified 34 ongoing studies. The available evidence is limited and does not demonstrate a clear benefit of smartphone applications as interventions for adolescents or adults with overweight or obesity. While the number of studies is growing, the evidence remains incomplete due to the high variability of the apps' features, content and components, which complicates direct comparisons and assessment of their effectiveness. Comparisons with either no or minimal intervention or personal coaching show minor effects, which are mostly not clinically significant. Minimal data for adolescents also warrants further research. Evidence is also scarce for low- and middle-income countries as well as for people with different socio-economic and cultural backgrounds. The 34 ongoing studies suggest sustained interest in the topic, with new evidence expected to emerge within the next two years. In practice, clinicians and healthcare practitioners should carefully consider the potential benefits, limitations, and evolving research when recommending smartphone apps to adolescents and adults with overweight or obesity.
Abstract Summary: Scientists wanted to see if smartphone apps help teenagers and grown-ups who weigh more than is healthy. They looked at studies where people used apps to try to be more active, eat better, or feel more confident about their health. They compared people who used these apps to those who didn't do much or used other methods like personal coaching.
They found that apps might help a little, but they're not sure. Some studies showed that apps didn't really change how much people exercised or their body weight after a year. They also didn't find much difference in how people felt about their health or their eating habits.
They checked a lot of studies, but the results weren't clear because the apps were all different. They also said we need more research, especially for teenagers and people in different countries or from different backgrounds.
For now, doctors should think carefully before suggesting these apps because we don't know how much they help. More studies are coming, so we might learn more soon.

Poorly controlled glycemia and worse beta cell function associate with higher resting and total energy expenditure in adults with obesity and type 2 diabetes: A doubly labeled water study.
Clin Nutr.
2024 Mar;
43(3):729-738.
Abstract: Some studies comparing persons with and without type 2 diabetes (T2DM) show no difference in resting energy expenditure (REE). However, the degree of glycemic control may be a crucial factor in determining energy requirements. Few studies have employed the doubly labeled water (DLW) method in persons with T2DM to objectively measure daily energy expenditure. To determine relationships between glycemia, body composition, and energy expenditure in adults with obesity and T2DM. We hypothesized that worse hyperglycemia, insulin resistance, and beta cell function would associate with higher resting and total energy expenditure (TEE). Two cohorts age 31-50 years were included: 78 with obesity and T2DM, 19 with normal weight and no chronic disease. Baseline data from clinical biomarkers, intravenous glucose tolerance tests, DXA and MRI for body composition, and dietary intakes were used in multivariable regression models to predict REE and TEE. Additionally, comparisons were made by categorizing participants as having controlled or uncontrolled glycemia based on glucose levels ≥175 mg/dL. REE was higher in participants with T2DM by 534.08 ± 74.35 kcal/d (p < 0.001). Higher fasting glucose and HbA1C levels associated with higher TEE. Abdominal SAT and VAT were also predictors in regression models accounting for 76 % of the variance in REE and 89 % of TEE. Participants with uncontrolled glycemia had 22 % higher adipose/lean ratio, two-fold higher VAT/SAT ratio, 21 % higher HOMA-IR score, and worse beta cell function (mean difference in HOMA2-%β of 74.09 ± 14.01, p < 0.001) than those with controlled glycemia. Both REE and TEE were significantly higher in uncontrolled glycemia, difference in REE of 154.17 ± 96.28 kcals/day (p = 0.04) and difference in TEE of 480.64 ± 215.45 kcals/day (p = 0.03). Poor beta cell function and uncontrolled glycemia associate with higher REE and TEE in persons with obesity and T2DM. This study is registered with clinicaltrials.gov identifier: NCT01239550.
Abstract Summary: Scientists did a study to see if people with type 2 diabetes and obesity use more energy when resting and during the day than people without diabetes. They used special tests to measure body fat and muscle, blood sugar levels, and how much energy people used. They found that people with higher blood sugar and more belly fat used more energy. Also, people whose diabetes wasn't well-controlled used more energy than those who had their diabetes under control. This research helps us understand that when people have diabetes that isn't well-managed, their bodies might need more energy. This is important for doctors to know when helping people with diabetes plan their diets and manage their health.

Primary and Secondary Cardiovascular and Kidney Prevention With Canagliflozin: Insights From the CANVAS Program and CREDENCE Trial.
J Am Heart Assoc.
2024 Feb 6;
13(3):e031586.
Abstract: This study evaluated the effects of canagliflozin in patients with type 2 diabetes with and without prevalent cardiovascular disease (secondary and primary prevention). This was a pooled participant-level analysis of the CANVAS (Canagliflozin Cardiovascular Assessment Study) Program and CREDENCE (Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation) trial. The CANVAS Program included participants with type 2 diabetes at elevated cardiovascular risk, whereas the CREDENCE trial included participants with type 2 diabetes and albuminuric chronic kidney disease. Hazard ratios (HRs) with interaction terms were obtained from Cox regression models to estimate relative risk reduction with canagliflozin versus placebo across the primary and secondary prevention groups. We analyzed 5616 (38.9%) and 8804 (61.1%) individuals in the primary and secondary prevention subgroups, respectively. Primary versus secondary prevention participants were on average younger (62.2 versus 63.8 years of age) and more often women (42% versus 31%). Canagliflozin reduced the risk of major adverse cardiovascular events (HR, 0.84 [95% CI, 0.76-0.94]) consistently across primary and secondary prevention subgroups (=0.86). Similarly, no treatment effect heterogeneity was observed with canagliflozin for hospitalization for heart failure, cardiovascular death, end-stage kidney disease, or all-cause mortality (all >0.5). Canagliflozin reduced cardiovascular and kidney outcomes with no statistical evidence of heterogeneity for the treatment effect across the primary and secondary prevention subgroups in the CANVAS Program and CREDENCE trial. Although studies on the optimal implementation of canagliflozin within these populations are warranted, these results reinforce canagliflozin's role in cardiorenal prevention and treatment in individuals with type 2 diabetes. URL: https://www.clinicaltrials.gov; Unique identifiers: NCT01032629, NCT01989754, NCT02065791.
Abstract Summary: Scientists looked at how a medicine called canagliflozin helps people with type 2 diabetes, especially those who already have heart problems or are at risk of getting them. They used information from two big studies that included lots of people with diabetes, some with kidney disease too. They found that canagliflozin was good at lowering the chance of having heart issues or kidney problems, no matter if the person already had heart disease or not. This is important because it means that this medicine can help lots of people with diabetes stay healthier by protecting their hearts and kidneys.

2023;
7(1):e251.
Abstract: Improving the quality and conduct of multi-center clinical trials is essential to the generation of generalizable knowledge about the safety and efficacy of healthcare treatments. Despite significant effort and expense, many clinical trials are unsuccessful. The National Center for Advancing Translational Science launched the Trial Innovation Network to address critical roadblocks in multi-center trials by leveraging existing infrastructure and developing operational innovations. We provide an overview of the roadblocks that led to opportunities for operational innovation, our work to develop, define, and map innovations across the network, and how we implemented and disseminated mature innovations.
Abstract Summary: Scientists do experiments called clinical trials to find out if medical treatments are safe and work well. Sometimes, these trials involve many hospitals and can be hard to do right, which can make the results not very helpful. To fix this, a group called the Trial Innovation Network was made. They use what hospitals already have and come up with new ways to do things better. This study talks about the problems they found and the new ideas they used to make clinical trials better. They also share how they put these ideas into action so that more people can use them. This helps make sure that when doctors treat patients, they are using the best and safest methods.

Examining the New Consensus Criteria for Traumatic Encephalopathy Syndrome in Community-Dwelling Older Adults.

2024 Apr;
41(7-8):957-968.
Abstract: In 2021, an expert panel of clinician-scientists published the first consensus research diagnostic criteria for traumatic encephalopathy syndrome (TES), a clinical condition thought to be associated with chronic traumatic encephalopathy neuropathological change. This study evaluated the TES criteria in older adults and assessed associations between TES criteria and a history of repetitive head impacts. This cross-sectional, survey-based study examined the symptoms of TES, previous repetitive head impacts, and a variety of current health difficulties. To meet symptom criteria for TES, participants had to report progressive changes with memory, executive functioning, and/or neurobehavioral dysregulation. To meet the criterion for substantial exposure to repetitive head impacts via contact sports, participants reported at least 5 years of contact sport exposure (with 2+ years in high school or beyond). A sample of 507 older adults (mean age = 70.0 years, 65% women) completed the survey and 26.2% endorsed having one or more of the progressive core clinical features of TES. Those who had a significant history of contact sport exposure were not significantly more likely to meet TES criteria compared with those who did not (31.3% vs. 25.3%, = 0.46). In a binary logistic regression predicting TES status, current depression or anxiety (odds ratio [OR] = 12.55; 95% confidence interval [CI] = 4.43-35.51), history of psychiatric disorders (OR = 2.07, 95% CI = 1.22-3.49), male sex (OR = 1.87), and sleep problems (OR = 1.71, 95% CI = 1.01-2.91) were associated with meeting TES criteria. The sport exposure criterion, age, and current pain were not significantly associated with TES status (s > 0.05). A significant minority of participants with no history of neurotrauma endorsed symptoms consistent with TES (22.0% of men and 19.8% of women). Nearly 80% of neurotrauma naïve participants with clinically significant anxiety/depression met criteria for TES. In summary, approximately one in four older adults met the symptom criteria for TES, many of whom had no history of repetitive neurotrauma. Mental health problems and sleep issues were associated with TES, whereas having a history of repetitive head impacts in contact sports was not. These data suggest that the new consensus diagnostic criteria for TES may have low specificity and may carry a higher risk of misdiagnosing those with other physical and mental health conditions as having TES.
Abstract Summary: Scientists did a study to learn about a brain problem called traumatic encephalopathy syndrome (TES), which they think might happen because of repeated head injuries. They asked 507 older people (around 70 years old) about their health, if they played contact sports for many years, and if they had certain symptoms like memory problems or mood changes. They found that about 1 in 4 of these older people had symptoms that could mean they have TES. But, interestingly, having played contact sports a lot didn't make it more likely for someone to have TES. Instead, people who felt sad or anxious, or had trouble sleeping, were more likely to have these symptoms. Some people who never had head injuries also had symptoms like TES. This means the way doctors decide if someone has TES might mix it up with other health issues, and they need to be careful not to make the wrong diagnosis.

15(1):401-411.
Abstract: Chronic inflammation and insulin resistance are highly prevalent in patients on maintenance haemodialysis (MHD) and are strongly associated with protein energy wasting. We conducted a pilot, randomized, placebo-controlled trial of recombinant human interleukin-1 receptor antagonist (IL-1ra) and pioglitazone to explore the safety, feasibility and efficacy for insulin-mediated protein metabolism in patients undergoing MHD. Twenty-four patients were randomized to receive IL-1ra, pioglitazone or placebo for 12 weeks. Changes in serum inflammatory markers and insulin-mediated protein synthesis, breakdown and net balance in the whole-body and skeletal muscle compartments were assessed using hyperinsulinaemic-hyperaminoacidemic clamp technique at baseline and Week 12. Among 24 patients, median (interquartile range) age was 51 (40, 61), 79% were African American and 21% had diabetes mellitus. All patients initiated on intervention completed the study, and no serious adverse events were observed. There was a statistically significant decrease in serum high-sensitivity C-reactive protein in the pioglitazone group compared with placebo, but not in the IL-1ra group. No significant differences in the changes of whole-body or skeletal muscle protein synthesis, breakdown and net balance were found between the groups. In this pilot study, there were no statistically significant effects of 12 weeks of IL-1ra or pioglitazone on protein metabolism in patients on MHD. gov registration: NCT02278562.
Abstract Summary: Doctors wanted to see if two medicines could help people on dialysis with inflammation and trouble using insulin, which can make them lose muscle and energy. They tested 24 patients, giving some a medicine called IL-1ra, some another called pioglitazone, and some a fake pill for 12 weeks. They checked for inflammation and how the body made and broke down proteins. Most patients were African American, and a few had diabetes. Everyone finished the study safely. The pioglitazone group had less inflammation, but overall, the medicines didn't really change how the body handled proteins. This was just a first test to learn more.

Abstract: Tau is a key pathology in chronic traumatic encephalopathy (CTE). Here, we report our findings in tau positron emission tomography (PET) measurements from the DIAGNOSE CTE Research Project. We compare flortaucipir PET measures from 104 former professional players (PRO), 58 former college football players (COL), and 56 same-age men without exposure to repetitive head impacts (RHI) or traumatic brain injury (unexposed [UE]); characterize their associations with RHI exposure; and compare players who did or did not meet diagnostic criteria for traumatic encephalopathy syndrome (TES). Significantly elevated flortaucipir uptake was observed in former football players (PRO+COL) in prespecified regions (p < 0.05). Association between regional flortaucipir uptake and estimated cumulative head impact exposure was only observed in the superior frontal region in former players over 60 years old. Flortaucipir PET was not able to differentiate TES groups. Additional studies are needed to further understand tau pathology in CTE and other individuals with a history of RHI.
Abstract Summary: Scientists did a study to learn more about a brain problem called chronic traumatic encephalopathy (CTE), which can happen to people who have had many head injuries. They used a special brain scan called PET to look at a substance called tau, which builds up in the brains of people with CTE. They compared the brain scans of 104 ex-professional football players, 58 ex-college football players, and 56 older men who never had lots of head injuries. They found that the football players had more tau in certain parts of their brains. Older players over 60 showed a link between tau and the number of times they hit their heads while playing. But the scans couldn't tell if someone had the symptoms of CTE. More research is needed to understand how tau affects the brain after many head injuries. This study is important because it helps us learn how playing football might change the brain and how to tell if someone has CTE.

Abstract: Autism spectrum disorder (ASD) is characterized by challenges in social competence that persist in adulthood, yet few treatment options exist. A pilot randomized clinical trial (RCT) of a peer-mediated, theatre-based intervention with established efficacy in youth with ASD was examined in autistic adults. The final sample consisted of forty-seven 18-to-40-year-old participants randomized to the experimental (EXP N = 23) or waitlist control (WLC N = 24) condition. A multimodal, social interdependent model was employed to examine social competence changes in brain (incidental face memory (IFM) using event-related potentials), cognition (Wechsler Memory Scale-III), behavior (Contextual Assessment of Social Skills) and function (Social Responsiveness Scale (SRS); Adaptive Behavior Assessment Scale (ABAS) Social Composite). Using analysis of covariance in which pretest was controlled in the model, posttest between-group differences were observed on IFM (p = 0.016, η = 0.139, d = 0.79) and several social and adaptive functional (SRS, ABAS) outcomes in social communication and interaction (SCI) (p = 0.019, η = 0.121, d = -00.45), communication (p = 0.044 η = 0.09, d = -00.31), and motivation (p = 0.001, η = 0.229, d = -0.79) domains. At two-month follow-up, gains in social motivation remained (p = 0.041, η = 0.100, d = -0.77). The results offer preliminary support for a unique theatre-based social skills intervention for autistic adults who have few treatment options to enhance social competence. The trial was pre-registered with ClinicalTrials.gov (Identifier: NCT04349644).
Abstract Summary: Scientists did a study to see if a special theater program could help adults with autism get better at social skills. Autism makes it hard for people to interact with others, and there aren't many treatments for adults. They had 47 adults with autism, ages 18 to 40, try out the program. Some started right away, and others waited a bit (the waitlist group). They checked how well the program worked by looking at how the adults remembered faces, how they thought, how they acted in social situations, and how they got along in everyday life.
They found that the adults who did the theater program got better at remembering faces and improved in talking to others, understanding social cues, and wanting to be social. These improvements were still there two months later. This study shows that the theater program might be a good way for adults with autism to improve their social skills.

Abstract: Angiopoietin 2 regulates endothelial function partially mediated by vascular endothelial growth factor-A (VEGF-A) and may play a role in diabetic kidney disease (DKD). We assessed the association of angiopoietin 2 and VEGF-A with cardiorenal outcomes and investigated the effect of canagliflozin on angiopoietin 2 and VEGF-A concentrations. Two thousand five hundred sixty-five study participants with DKD and available plasma samples treated with canagliflozin or placebo in the Canagliflozin and Kidney Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial were included. Angiopoietin 2 and VEGF-A concentrations were measured at baseline, year 1, and year 3. The primary composite end point of the trial was a composite of kidney failure, doubling of the serum creatinine level, and kidney or cardiovascular death. Patients with the highest baseline quartile of angiopoietin 2, but not VEGF-A, concentration had the highest risk clinical profile. Treatment with canagliflozin significantly lowered concentrations of angiopoietin 2 (adjusted geometric mean ratio: 0.94; 95% confidence interval, 0.92 to 0.95; P < 0.001), but not VEGF-A. In multivariable-adjusted modeling, each 50% increment in log baseline angiopoietin 2 concentrations was associated with a higher risk of primary composite outcome (hazard ratio, 1.27; 95% confidence interval, 1.13 to 1.43). Angiopoietin 2 change at year 1 compared with baseline explained 10% of the effect of canagliflozin on the primary composite outcome. VEGF-A concentrations were not associated with outcomes, alone or in combination with angiopoietin 2. Higher angiopoietin 2 levels were associated with cardiorenal risk among individuals with DKD independent of VEGF-A. Canagliflozin lowered angiopoietin 2 concentrations. Evaluation of the Effects of Canagliflozin on Renal and Cardiovascular Outcomes in Participants With Diabetic Nephropathy, NCT02065791 .
Abstract Summary: Scientists did a study to see if a medicine called canagliflozin could help people with a kind of kidney disease that happens because of diabetes. They looked at two things in the blood, angiopoietin 2 and VEGF-A, to see if they were connected to heart and kidney problems. They tested the blood of 2,565 people with this kidney disease, both before and after giving them the medicine or a placebo.
They found that people with higher levels of angiopoietin 2 had more health risks, but this wasn't true for VEGF-A. The good news is that the medicine canagliflozin helped lower the levels of angiopoietin 2. This drop in angiopoietin 2 seemed to explain some of the good effects of the medicine on the heart and kidneys. VEGF-A levels didn't really change and didn't seem to affect people's health in this study.
So, the big takeaway is that canagliflozin might be a helpful medicine for people with kidney problems from diabetes because it lowers angiopoietin 2 in the blood.

Abstract: To examine the feasibility, acceptability, and preliminary efficacy of a positive affect skills intervention for middle-aged and older adults with fibromyalgia syndrome (FMS). Ninety-five participants with FMS aged 50 and older (94% female) were randomized to 1 of 2 conditions: (a) Lessons in Affect Regulation to Keep Stress and Pain UndeR control (LARKSPUR; = 49) or (b) emotion reporting/control ( = 46). LARKSPUR included 5 weeks of skill training that targeted 8 skills to help foster positive affect, including (a) noticing positive events, (b) savoring positive events, (c) identifying personal strengths, (d) behavioral activation to set and work toward attainable goals, (e) mindfulness, (f) positive reappraisal, (g) gratitude, and (h) acts of kindness. Outcome data were collected via online surveys at baseline, postintervention, and 1-month follow-up. Completion rates (88%) and satisfaction ratings (10-point scale) were high (LARKSPUR: = 9.14, standard deviation () = 1.49; control: = 8.59, = 1.97). Improvements were greater in LARKSPUR participants compared with control participants on measures of positive affect (Cohen's = 0.19 [0.15, 0.24]), negative affect (Cohen's = -0.07 [-0.11, -0.02]), and pain catastrophizing (Cohen's = -0.14 [-0.23, -0.05]). Improvements in positive affect (Cohen's = 0.17 [0.13, 0.22]) and negative affect (Cohen's = -0.11 [-0.15, -0.06]) were maintained at 1-month follow-up. Dose-response analyses indicated that intervention engagement significantly predicted pre-to-post and post-to-follow-up reductions in pain catastrophizing. The current preliminary findings add to existing literature and highlight the specific potential of internet-delivered positive affect skills programs for adults with FMS. NCT04869345.
Abstract Summary: Scientists did a study to see if teaching older people with fibromyalgia (a condition that causes pain all over the body) how to feel more positive could help them feel better. They had 95 people over 50 years old join the study. These people were split into two groups. One group learned special skills for five weeks to help them notice and enjoy good things, understand their strengths, set goals, be mindful, think positively, be thankful, and do kind things. The other group just reported on their feelings.
They checked how the people were doing before, right after, and one month after the study. Most people finished the study and liked it a lot. The group that learned the special skills felt more positive, less negative, and didn't think about their pain in a bad way as much as the other group. These good changes stayed even one month later. The more people practiced these skills, the less they felt bad about their pain.
This study shows that learning to feel more positive through the internet can really help adults with fibromyalgia feel better.

Online psychoeducation and digital assessments as a first step of treatment for borderline personality disorder: A protocol for a pilot randomized controlled trial.
PLoS One.
2023;
18(12):e0294331.
Abstract: Treatment trials for borderline personality disorder (BPD) have consistently demonstrated that approaches that are diagnostically tailored are superior to those which are not. Currently, gold standard treatments for BPD are highly intensive, lengthy, and specialized, leading to a critical gap between the supply and demand of effective, evidence-based treatment for patients who receive a diagnosis of BPD. Psychoeducation, which is a common component of most treatments known to be effective, is a low-cost, low-burden intervention proven to relieve symptoms. The present study builds on psychoeducation research, assessing online video prescriptions as a means of disseminating information patients need to know about their diagnosis and care. This article presents the study protocol for a safety, feasibility, and preliminary efficacy trial of psychoeducational video prescriptions and online assessment with feedback for newly diagnosed individuals with BPD. We aim to recruit 100 adults recently diagnosed with BPD to be randomly assigned to receive videos about BPD or videos about non-BPD mental health topics that are matched in length in the first step of the study. All participants will complete daily surveys about their emotions, interpersonal interactions, and behaviors, as well as self-report assessments and cognitive tests at 4 different time points. Half of the participants in the intervention group will receive feedback on their symptom ratings and cognitive test performance to assess whether there is incremental value in tailoring this online set of interventions with individualized feedback unique to each participant. This study aims to assess the effects of BPD-focused psychoeducational videos with and without personalized feedback, on BPD and depressive symptom severity as well as core mechanisms of the disorder such as loneliness, rejection sensitivity, cognitive control difficulties, and self-clarity. Results will inform efforts to progress to a larger, more definitive trial. Clinical trials registration: The protocol is registered with ClinicalTrials.gov NCT05358925.
Abstract Summary: Scientists are studying a new way to help people with a mental health issue called borderline personality disorder (BPD). They want to see if watching special videos online can help these people feel better. The videos will teach them about BPD and how to handle it. There will be 100 adults who have just found out they have BPD taking part in the study. They will be split into two groups. One group will watch the BPD videos, and the other group will watch videos about other mental health topics. Everyone will answer questions every day about how they feel and act. They will also take some tests on the computer. Some people will get extra help by getting feedback on how they're doing. The study will check if the videos and the extra feedback can make people with BPD feel less lonely, less sensitive to feeling rejected, think clearer, and understand themselves better. If this works, it could lead to more studies and help lots of people with BPD in an easy and cheap way. The study's details are saved on a website called ClinicalTrials.gov with the number NCT05358925.

Reducing fear and avoidance of memory loss improves mood and social engagement in community-based older adults: a randomized trial.
BMC Geriatr.
2023 Nov 29;
23(1):786.
Abstract: Alzheimer's disease and related dementias (ADRD) are among the most feared age-related conditions. The aim of this study was to evaluate a brief psychological intervention to promote adaptive coping in older adults experiencing heightened fear of ADRD and investigate positive downstream effects on health-related secondary outcomes, including frequency of reported memory failures, psychosocial functioning, and quality of life. Eighty-one older adults were recruited and randomized into REFRAME or active control intervention arms. Both groups received psycho-education and training in mindful monitoring of fears related to ADRD. The REFRAME group received an additional behavioral activation component intended to disrupt maladaptive avoidant coping (i.e., avoidance) strategies. Both groups completed 3-weeks of intervention exercises with accompanying questionnaires (baseline, mid- and post-intervention and 4-week follow-up). Adherence was strong (> 75%). We observed a significant reduction in ADRD-related fear and avoidance in both groups. Significant reductions were also observed for frequency of self-reported memory failures, anxiety, and depression. Depression was significantly reduced in the REFRAME group compared to the control group. Significant increases in participants' ability to participate in social activities and well-being were also observed. Findings suggest that a brief psychological intervention can mitigate ADRD-related fears and avoidant coping in older adults, and that benefits extend to broader health-related outcomes including anxiety, depression, social functioning, and well-being. Addressing ADRD-related fear has implications for healthy aging and risk reduction, as individuals may be more likely to engage in activities that are protective against ADRD but were previously avoided. https://clinicaltrials.gov/ct2/show/NCT04821960 .
Abstract Summary: Scientists did a study to help older people who are really scared of getting Alzheimer's disease or similar problems. They wanted to see if a special short program could make them feel better and improve their lives. They had 81 older people try two different programs. Both programs taught them about the disease and how to be aware of their fears without letting them take over. One program also had extra activities to help people stop avoiding things they were scared of. They checked on the people for a few weeks to see how they were doing.
The good news is that both programs helped the people feel less scared and less likely to avoid things because of their fear. They also felt better about their memory, were less anxious and sad, and enjoyed being with others more. The program with the extra activities was even better at helping with sadness. This study is important because it shows that a short program can make a big difference for older people who are worried about losing their memory and can help them stay active and happy.

ResearchMatch on FHIR: Development and evaluation of a recruitment registry and electronic health record system interface for volunteer profile completion.
J Clin Transl Sci.
2023;
7(1):e222.
Abstract: Obtaining complete and accurate information in recruitment registries is essential for matching potential participants to research studies for which they qualify. Since electronic health record (EHR) systems are required to make patient data available to external systems, an interface between EHRs and recruitment registries may improve accuracy and completeness of volunteers' profiles. We tested this hypothesis on ResearchMatch (RM), a disease- and institution-neutral recruitment registry with 1357 studies across 255 institutions. We developed an interface where volunteers signing up for RM can authorize transfer of demographic data, medical conditions, and medications from the EHR into a registration form. We obtained feedback from a panel of community members to determine acceptability of the planned integration. We then developed the EHR interface and performed an evaluation study of 100 patients to determine whether RM profiles generated with EHR-assisted adjudication included more conditions and medications than those without the EHR connection. Community member feedback revealed that members of the public were willing to authenticate into the EHR from RM with proper messaging about choice and privacy. The evaluation study showed that out of 100 participants, 75 included more conditions and 69 included more medications in RM profiles completed with the EHR connection than those without. Participants also completed the EHR-connected profiles in 16 fewer seconds than non-EHR-connected profiles. The EHR to RM integration could lead to more complete profiles, less participant burden, and better study matches for many of the over 148,000 volunteers who participate in ResearchMatch.
Abstract Summary: Scientists wanted to see if they could get better information about volunteers who want to join research studies. They thought that using electronic health records (EHR) could help. They tried this idea on a big list called ResearchMatch that helps match volunteers with studies. They made a system where volunteers could let their health information be added to their ResearchMatch profile. They asked people what they thought about this and then tested it with 100 patients. They found that profiles with health record information had more details about health conditions and medicines. Also, these profiles were finished faster. This could help volunteers find the right studies more easily.

Long-term blood pressure variability and frailty risk in older adults.
J Hypertens.
2024 Feb 1;
42(2):244-251.
Abstract: In healthy older adults, the relationship between long-term, visit-to-visit variability in blood pressure (BP) and frailty is uncertain. Secondary analysis of blood pressure variability (BPV) and incident frailty in >13 000 participants ≥65-70 years enrolled in the ASPirin in Reducing Events in the Elderly (ASPREE) trial and its observational follow-up (ASPREE-XT). Participants were without dementia, physical disability, or cardiovascular disease at baseline. BPV was estimated using standard deviation of mean BP from three annual visits (baseline through the second annual follow-up). Frailty was defined using Fried phenotype and a frailty deficit accumulation index (FDAI). Participants with frailty during the BPV estimation period were excluded from the main analysis. Adjusted Cox proportional hazards regression evaluated the association between BPV and incident frailty, and linear mixed models for change in frailty scores, through a maximum of 9 years of follow-up. Participants in the highest systolic BPV tertile were at higher risk of frailty compared to those in the lowest (referent) tertile of systolic BPV [Fried hazard ratio (HR) 1.17, 95% confidence interval (CI) 1.04-1.31; FDAI HR 1.18, 95% CI 1.07-1.30]. Findings were consistent when adjusted for multiple covariates and when stratified by antihypertensive use. Linear mixed models showed that higher systolic BPV was associated with increasing frailty score over time. Diastolic BPV was not consistently associated. High systolic BPV, independent of mean BP, is associated with increased risk of frailty in healthy older adults. Variability of BP across visits, even in healthy older adults, can convey important risk information beyond mean BP. ClinicalTrials.gov NCT01038583 and ISRCTN83772183.
Abstract Summary: Scientists did a study to see if changes in blood pressure over time could make older people more likely to become frail. They looked at over 13,000 people who were 65-70 years old and healthy. These people didn't have memory problems, trouble moving around, or heart disease when the study started. The researchers checked their blood pressure several times over three years and then watched them for up to nine years. They found that older adults whose blood pressure went up and down a lot were more likely to become frail than those whose blood pressure stayed the same. This was true even when they considered other health factors and whether the person was taking medicine for high blood pressure. The study shows that for older adults, keeping blood pressure steady is important for staying strong and healthy.

The role of endogenous opioids in mindfulness and sham mindfulness-meditation for the direct alleviation of evoked chronic low back pain: a randomized clinical trial.
Neuropsychopharmacology.
2024 Jun;
49(7):1069-1077.
Abstract: Chronic low back pain (cLBP) is the most prevalent chronic pain condition. There are no treatments that haven been found to directly assuage evoked cLBP. To this extent, mindfulness-meditation is a promising pain therapy. Yet, it is unclear if meditation can be utilized to directly attenuate evoked chronic pain through endogenous opioids. A double-blind, randomized, and placebo-controlled clinical trial with a drug crossover design examined if mindfulness-meditation, as compared to sham mindfulness-meditation, attenuated straight leg-raise test evoked chronic pain during intravenous (0.15 mg/kg bolus + 0.15 mg/kg/hour maintenance) naloxone (opioid antagonist) and placebo-saline infusion. Fifty-nine individuals with cLBP (mean age = 46 years; 30 females) completed all study procedures. After the pre-intervention pain testing session, patients were randomized to a four-session (20-min/session) mindfulness (n = 30) or sham mindfulness-meditation (n = 29) intervention. After the interventions, mindfulness and sham mindfulness-meditation were associated with significant reductions in back pain during saline and naloxone infusion when compared to rest (non-meditation) in response to the cLBP-evoking straight leg-raise test. These results indicate that meditation directly reduces evoked chronic pain through non-opioidergic processes. Importantly, after the interventions, the mindfulness group reported significantly lower straight leg-raise induced pain than the sham mindfulness-meditation group during rest (non-meditation) and meditation. Mindfulness and sham mindfulness-meditation training was also associated with significantly lower Brief Pain Inventory severity and interference scores. The pain-relieving effects of mindfulness meditation were more pronounced than a robust sham-mindfulness meditation intervention, suggesting that non-reactive appraisal processes may be uniquely associated with improvements in chronic low-back pain.Trial Registration: ClinicalTrials.gov identifier: NCT04034004.
Abstract Summary: Scientists did a study to see if a special kind of thinking exercise called mindfulness meditation can help people with long-lasting back pain. They had 59 people with this kind of pain try either real meditation or a pretend meditation. They also gave them a medicine that usually blocks pain relief or a saltwater shot that does nothing. They found that both real and pretend meditation helped reduce the pain more than just resting. But the real meditation was better at easing pain during the leg-raising test and also helped people feel less pain in their daily lives. This means that mindfulness meditation might help with back pain in a way that doesn't involve the body's usual painkillers.

Independent and Interactive Associations of Subjective and Objective Socioeconomic Status With Body Composition and Parent-Reported Hyperphagia Among Children.
Child Obes.
2024 Sep;
20(6):394-402.
Abstract: Subjective socioeconomic status (SSES) and objective socioeconomic status (OSES) have been independently associated with body composition and eating behavior in children. While low OSES may constrain access to healthier foods, low SSES has been associated with increased preference for and motivation to consume higher energy foods and portions independent of OSES. Despite these distinct ways that OSES and SSES may affect children's eating behavior and adiposity, their joint contributions remain unclear. We investigated the independent and interactive associations of SSES and OSES with children's BMI, fat mass index (FMI), and caregiver-reported hyperphagia. Data were derived from the Children's Growth and Behavior Study, an ongoing observational study. Multiple linear regressions used child's SSES and OSES of the family as independent factors and modeled the statistical interaction of SSES and OSES with BMI ( = 128), FMI ( = 122), and hyperphagia and its subscales ( = 76) as dependent variables. SSES was independently and negatively associated with hyperphagia severity and OSES was independently and negatively associated with both FMI and hyperphagia severity. There was a statistical interaction effect of SSES and OSES on hyperphagia severity-lower SSES was associated with greater hyperphagia severity only at lower levels of OSES. These findings demonstrate a relationship between low OSES and child adiposity and that the relationship between child SSES and hyperphagia severity may be most relevant for children from households with lower family OSES. Future research on socioeconomic disparities in children's body composition and eating behaviors should examine the interaction of SSES and OSES. NCT02390765.
Abstract Summary: Scientists did a study to see how kids' feelings about their family's money (SSES) and their family's actual money situation (OSES) are linked to their body size and eating habits. They found that when kids feel like their family has less money, they might want to eat more, especially if their family really does have less money. Also, when a family has less money, kids might have more body fat. This study helps us understand that both how kids feel about money and their family's real money situation can affect how much they eat and their body size. It's important to think about both of these things when trying to help kids stay healthy.

Abstract: Incorporating blood-based Alzheimer's disease biomarkers such as tau and amyloid beta (Aβ) into screening algorithms may improve screening efficiency. Plasma Aβ, phosphorylated tau (p-tau)181, and p-tau217 concentration levels from AHEAD 3-45 study participants were measured using mass spectrometry. Tau concentration ratios for each proteoform were calculated to normalize for inter-individual differences. Receiver operating characteristic (ROC) curve analysis was performed for each biomarker against amyloid positivity, defined by > 20 Centiloids. Mixture of experts analysis assessed the value of including tau concentration ratios into the existing predictive algorithm for amyloid positron emission tomography status. The area under the receiver operating curve (AUC) was 0.87 for Aβ42/Aβ40, 0.74 for phosphorylated variant p-tau181 ratio (p-tau181/np-tau181), and 0.92 for phosphorylated variant p-tau217 ratio (p-tau217/np-tau217). The Plasma Predicted Centiloid (PPC), a predictive model including p-tau217/np-tau217, Aβ42/Aβ40, age, and apolipoprotein E improved AUC to 0.95. Including plasma p-tau217/np-tau217 along with Aβ42/Aβ40 in predictive algorithms may streamline screening preclinical individuals into anti-amyloid clinical trials. gov Identifier: NCT04468659 HIGHLIGHTS: The addition of plasma phosphorylated variant p-tau217 ratio (p-tau217/np-tau217) significantly improved plasma biomarker algorithms for identifying preclinical amyloid positron emission tomography positivity. Prediction performance at higher NAV Centiloid levels was improved with p-tau217/np-tau217. All models generated for this study are incorporated into the Plasma Predicted Centiloid (PPC) app for public use.
Abstract Summary: Scientists are studying new ways to find out if someone might get Alzheimer's disease by looking at special signs in their blood. They checked levels of certain proteins in the blood of people who might get Alzheimer's. They found that by measuring these proteins, they could guess who might have signs of Alzheimer's in their brain scans. They made a special app that uses this information to help doctors guess better. This could help people get into studies for new Alzheimer's treatments earlier.

2023 Nov 7;
12(21):e031459.
Abstract: Background The risk of atherosclerotic cardiovascular disease (ASCVD) increases sharply with age. Some older individuals, however, remain unaffected despite high predicted risk. These individuals may carry cardioprotective genetic variants that contribute to resilience. Our aim was to assess whether asymptomatic older individuals without prevalent ASCVD carry cardioprotective genetic variants that contribute to ASCVD resilience. Methods and Results We performed a genome-wide association study using a 10-year predicted ASCVD risk score as a quantitative trait, calculated only in asymptomatic older individuals aged ≥70 years without prevalent ASCVD. Our discovery genome-wide association study of N=12 031 ASCVD event-free individuals from the ASPREE (Aspirin in Reducing Events in the Elderly) trial identified 2 independent variants, rs9939224 (<5×10) and rs56156922 (<10), in the (cholesteryl ester transfer protein) gene. The gene is a regulator of plasma high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and lipoprotein(a) levels, and it is a therapeutic drug target. The associations were replicated in the UK Biobank (subpopulation of N=13 888 individuals aged ≥69 years without prevalent ASCVD). Carriers of the identified variants (versus noncarriers) had higher plasma high-density lipoprotein cholesterol levels, lower plasma low-density lipoprotein cholesterol levels, and reduced risk of incident ASCVD events during follow-up. Expression quantitative trait loci analysis predicted the identified variants reduce gene expression across various tissues. Previously reported associations between genetic inhibition and increased risk of age-related macular degeneration were not observed among the 3917 ASPREE trial participants with retinal imaging and genetic data available. Conclusions Common genetic variants in the gene region are associated with cardiovascular resilience during aging. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT01038583.
Abstract Summary: Scientists wanted to find out why some older people don't get heart diseases even when they have a high chance of getting them. They thought these people might have special genes that protect their hearts. To find out, they looked at the genes of over 12,000 older people who didn't have heart diseases. They found two special parts in a gene that seemed to help keep these people's hearts healthy. This gene helps control the levels of good and bad fats in the blood, which are important for heart health. They checked their findings with another big group of older people and found the same thing. People with these special gene parts had better fat levels in their blood and a lower chance of getting heart diseases. This discovery is important because it could help us understand how to protect more people's hearts as they get older.

Abstract: This study evaluates the extent to which automated indices of vocal development are stable and valid for predicting language in infants at increased familial likelihood for autism and/or language impairment and relatively lower likelihood infants. A group of infants with autistic siblings (Sibs-autism; 20 infants) and a comparison group of infants with non-autistic siblings (Sibs-NA; 20 infants) wore Language ENvironment Analysis (LENA) recording devices for 16 hr on 2 days within a 1-week period. Extant software was used to derive several putative indices of vocal development from these recordings. Stability of these variables was examined across and within groups. Expressive and receptive language aggregates were calculated for each participant. Multiple regression analyses were used to (a) evaluate zero-order correlations for variables derived from LENA recordings with concurrent and future language and (b) test whether those associations were moderated by group status. Both stability and validity differed by variable and group status. All variables reached acceptable stability in the Sibs-autism group within two to three observations, whereas stability of most variables was attenuated in the Sibs-NA group. No variables were associated with concurrent language in the theoretically motivated direction across groups, but two variables were strongly associated with concurrent expressive language in only the Sibs-NA group. Additionally, two variables were associated with later expressive language, though these correlations were again stronger in the Sibs-NA versus Sibs-autism group. Although selected automated indices of vocal development were stable in Sibs-autism and/or valid for predicting expressive language within Sibs-NA, no scores showed strong, theoretically motivated associations with language within the Sibs-autism group. Automated indices of vocal development may, thus, have limited validity or clinical utility for predicting language development in infants at elevated familial likelihood for autism. https://doi.org/10.23641/asha.24415735.
Abstract Summary: Scientists did a study to see if a special tool that listens to baby talk can help tell how well babies might learn to talk later, especially babies who might have a higher chance of autism because they have brothers or sisters with autism. They had 20 babies with autistic siblings and 20 babies with non-autistic siblings wear a recording device for a whole day, twice in one week. They wanted to see if the sounds the babies made could predict their language skills now and in the future.
They found that the tool worked pretty well for the babies with autistic siblings if they checked a few times. But it wasn't as good for the other babies. The tool didn't really show if the babies with autistic siblings would have language problems later. For the other babies, it did a better job of guessing how well they would talk later on.
In the end, the study says that this tool might not be the best way to guess if a baby with a higher chance of autism will have trouble with language as they grow up.

Genome-Wide Association Study of Pericardial Fat Area in 28 161 UK Biobank Participants.

12(21):e030661.
Abstract: BACKGROUND Pericardial adipose tissue (PAT) is the visceral adipose tissue compartment surrounding the heart. Experimental and observational research has suggested that greater PAT deposition might mediate cardiovascular disease, independent of general or subcutaneous adiposity. We characterize the genetic architecture of adiposity-adjusted PAT and identify causal associations between PAT and adverse cardiac magnetic resonance imaging measures of cardiac structure and function in 28 161 UK Biobank participants. METHODS AND RESULTS The PAT phenotype was extracted from cardiac magnetic resonance images using an automated image analysis tool previously developed and validated in this cohort. A genome-wide association study was performed with PAT area set as the phenotype, adjusting for age, sex, and other measures of obesity. Functional mapping and Bayesian colocalization were used to understand the biologic role of identified variants. Mendelian randomization analysis was used to examine potential causal links between genetically determined PAT and cardiac magnetic resonance-derived measures of left ventricular structure and function. We discovered 12 genome-wide significant variants, with 2 independent sentinel variants (rs6428792, =4.20×10 and rs11992444, =1.30×10) at 2 distinct genomic loci, that were mapped to 3 potentially causal genes: T-box transcription factor 15 (), tryptophanyl tRNA synthetase 2, mitochondrial () and early B-cell factor-2 () through functional annotation. Bayesian colocalization additionally suggested a role of RP4-712E4.1. Genetically predicted differences in adiposity-adjusted PAT were causally associated with adverse left ventricular remodeling. CONCLUSIONS This study provides insights into the genetic architecture determining differential PAT deposition, identifies causal links with left structural and functional parameters, and provides novel data about the pathophysiological importance of adiposity distribution.
Abstract Summary: Scientists did a study to learn more about the fat that surrounds the heart, called pericardial adipose tissue (PAT). They wanted to see if having more PAT could cause heart problems, even if a person doesn't have too much fat elsewhere on their body. They looked at heart scans from over 28,000 people and used special computer tools to measure the PAT. They also checked the people's genes to find any that might be linked to having more PAT.
They found 12 spots in the genes that were important, and two of these spots were really special because they were connected to three genes that might explain why some people have more heart fat. They also used a special method to see if having more PAT could actually lead to changes in the heart that aren't good, like making it harder for the heart to pump blood.
The study showed that certain genes can make a person have more fat around their heart, and this can lead to heart problems. This information is important because it helps us understand that where fat is in the body can affect heart health, not just how much fat there is overall. This could help doctors find new ways to keep hearts healthy by focusing on PAT.

Effect of SGLT2 Inhibitors on Discontinuation of Renin-angiotensin System Blockade: A Joint Analysis of the CREDENCE and DAPA-CKD Trials.

Abstract: Angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) are foundational therapy for CKD but are underused, in part because they are frequently withheld and not restarted due to hyperkalemia, AKI, or hospitalization. Consequently, ensuring persistent use of ACE inhibitors and ARBs in CKD has long been a major clinical priority. In this joint analysis of the CREDENCE and DAPA-CKD trials, the relative risk of discontinuation of ACE inhibitors and ARBs was reduced by 15% in patients randomized to sodium-glucose cotransporter 2 (SGLT2) inhibitors. This effect was more pronounced in patients with urine albumin:creatinine ratio ≥1000 mg/g, for whom the absolute benefits of these medications are the greatest. These findings indicate that SGLT2 inhibitors may enable better use of ACE inhibitors and ARBs in patients with CKD. Strategies to enable persistent use of renin-angiotensin system (RAS) blockade to improve outcomes in CKD have long been sought. The effect of SGLT2 inhibitors on discontinuation of RAS blockade has yet to be evaluated. We conducted a joint analysis of canagliflozin and renal events in diabetes with established nephropathy clinical evaluation (CREDENCE) and dapagliflozin and prevention of adverse outcomes in CKD (DAPA-CKD), two randomized, double-blind, placebo-controlled, event-driven trials of SGLT2 inhibitors in patients with albuminuric CKD. The main outcome was time to incident temporary or permanent discontinuation of RAS blockade, defined as interruption of an ACE inhibitor or ARB for at least 4 weeks or complete cessation during the double-blind on-treatment period. Cox regression analyses were used to estimate the treatment effects from each trial. Hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) were pooled with fixed effects meta-analysis to obtain summary treatment effects, overall and across key subgroups. During median follow-up of 2.2 years across both trials, 740 of 8483 (8.7%) patients discontinued RAS blockade. The relative risk for discontinuation of RAS blockade was 15% lower in patients randomized to receiving SGLT2 inhibitors (HR, 0.85; 95% CI, 0.74 to 0.99), with consistent effects across trials ( P -heterogeneity = 0.92). The relative effect on RAS blockade discontinuation was more pronounced among patients with baseline urinary albumin:creatinine ratio ≥1000 mg/g (pooled HR, 0.77; 95% CI, 0.63 to 0.94; P -heterogeneity = 0.009). In patients with albuminuric CKD with and without type 2 diabetes, SGLT2 inhibitors facilitate the use of RAS blockade. ClinicalTrials.gov, NCT02065791 and NCT03036150 .

Abstract Summary: Doctors often give people with kidney problems special medicines to help their kidneys work better. But sometimes, they have to stop these medicines because they can cause other issues. This study looked at whether a different kind of medicine, called SGLT2 inhibitors, can help people keep taking their kidney medicines without having to stop. They found that people who took SGLT2 inhibitors didn't have to stop their kidney medicines as much. This is really good news because it means that people with kidney problems might be able to take their medicines longer and stay healthier.

Development and Validation of a New Hierarchical Composite End Point for Clinical Trials of Kidney Disease Progression.

Abstract: The established composite kidney end point in clinical trials combines clinical events with sustained large changes in GFR but does not weigh the relative clinical importance of the end point components. By contrast, a hierarchical composite end point (HCE) accounts for the clinical importance of the end point components. The authors developed and validated a kidney HCE that combines clinical kidney outcomes with longitudinal GFR changes (GFR slope). They demonstrate that in seven major placebo-controlled kidney outcome trials with different medications, treatment effect estimates on the HCE were consistently in similar directions and of similar magnitudes compared with treatment effects on the established kidney end point. The HCE's prioritization of clinical outcomes and ability to combine dichotomous outcomes with GFR slope make it an attractive alternative to the established kidney end point. The established composite kidney end point in clinical trials combines clinical events with sustained large changes in GFR. However, the statistical method does not weigh the relative clinical importance of the end point components. A HCE accounts for the clinical importance of the end point components and enables combining dichotomous outcomes with continuous measures. We developed and validated a new HCE for kidney disease progression, performing post hoc analyses of seven major Phase 3 placebo-controlled trials that assessed the effects of canagliflozin, dapagliflozin, finerenone, atrasentan, losartan, irbesartan, and aliskiren in patients with CKD. We calculated the win odds (WOs) for treatment effects on a kidney HCE, defined as a hierarchical composite of all-cause mortality; kidney failure; sustained 57%, 50%, and 40% GFR declines from baseline; and GFR slope. The WO describes the odds of a more favorable outcome for receiving the active compared with the control. We compared the WO with the hazard ratio (HR) of the primary kidney outcome of the original trials. In all trials, treatment effects calculated with the WO reflected a similar direction and magnitude of the treatment effect compared with the HR. Clinical trials incorporating the HCE would achieve increased statistical power compared with the established composite end point at equivalent sample sizes. In seven major kidney clinical trials, the WO and HR provided similar direction of treatment effect estimates with smaller HRs associated with larger WOs. The prioritization of clinical outcomes and inclusion of broader composite end points makes the HCE an attractive alternative to the established kidney end point.
Abstract Summary: Scientists did a study to find a better way to measure how well treatments work for kidney problems. They created a new system called a "hierarchical composite end point" (HCE) that looks at different results from treatments and decides which ones are more important. They tested this new system by looking at past studies where people with kidney disease took different medicines. They found that this new system showed the same results as the old way of measuring, but it was better because it could tell which treatments were more important for people's health. This new system could help doctors and scientists understand how well treatments work for kidney problems.

Haemostatic therapies for stroke due to acute, spontaneous intracerebral haemorrhage.

10(10):CD005951.
Abstract: Outcome after acute spontaneous (non-traumatic) intracerebral haemorrhage (ICH) is influenced by haematoma volume. ICH expansion occurs in about 20% of people with acute ICH. Early haemostatic therapy might improve outcome by limiting ICH expansion. This is an update of a Cochrane Review first published in 2006, and last updated in 2018. To examine 1. the effects of individual classes of haemostatic therapies, compared with placebo or open control, in adults with acute spontaneous ICH, and 2. the effects of each class of haemostatic therapy according to the use and type of antithrombotic drug before ICH onset. We searched the Cochrane Stroke Trials Register, CENTRAL (2022, Issue 8), MEDLINE Ovid, and Embase Ovid on 12 September 2022. To identify further published, ongoing, and unpublished randomised controlled trials (RCTs), we scanned bibliographies of relevant articles and searched international registers of RCTs in September 2022. We included RCTs of any haemostatic intervention (i.e. procoagulant treatments such as clotting factor concentrates, antifibrinolytic drugs, platelet transfusion, or agents to reverse the action of antithrombotic drugs) for acute spontaneous ICH, compared with placebo, open control, or an active comparator. We used standard Cochrane methods. Our primary outcome was death/dependence (modified Rankin Scale (mRS) 4 to 6) by day 90. Secondary outcomes were ICH expansion on brain imaging after 24 hours, all serious adverse events, thromboembolic adverse events, death from any cause, quality of life, mood, cognitive function, Barthel Index score, and death or dependence measured on the Extended Glasgow Outcome Scale by day 90. We included 20 RCTs involving 4652 participants: nine RCTs of recombinant activated factor VII (rFVIIa) versus placebo/open control (1549 participants), eight RCTs of antifibrinolytic drugs versus placebo/open control (2866 participants), one RCT of platelet transfusion versus open control (190 participants), and two RCTs of prothrombin complex concentrates (PCC) versus fresh frozen plasma (FFP) (47 participants). Four (20%) RCTs were at low risk of bias in all criteria. For rFVIIa versus placebo/open control for spontaneous ICH with or without surgery there was little to no difference in death/dependence by day 90 (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.74 to 1.05; 7 RCTs, 1454 participants; low-certainty evidence). We found little to no difference in ICH expansion between groups (RR 0.81, 95% CI 0.56 to 1.16; 4 RCTs, 220 participants; low-certainty evidence). There was little to no difference in all serious adverse events and death from any cause between groups (all serious adverse events: RR 0.81, 95% CI 0.30 to 2.22; 2 RCTs, 87 participants; very low-certainty evidence; death from any cause: RR 0.78, 95% CI 0.56 to 1.08; 8 RCTs, 1544 participants; moderate-certainty evidence). For antifibrinolytic drugs versus placebo/open control for spontaneous ICH, there was no difference in death/dependence by day 90 (RR 1.00, 95% CI 0.93 to 1.07; 5 RCTs, 2683 participants; high-certainty evidence). We found a slight reduction in ICH expansion with antifibrinolytic drugs for spontaneous ICH compared to placebo/open control (RR 0.86, 95% CI 0.76 to 0.96; 8 RCTs, 2866 participants; high-certainty evidence). There was little to no difference in all serious adverse events and death from any cause between groups (all serious adverse events: RR 1.02, 95% CI 0.75 to 1.39; 4 RCTs, 2599 participants; high-certainty evidence; death from any cause: RR 1.02, 95% CI 0.89 to 1.18; 8 RCTs, 2866 participants; high-certainty evidence). There was little to no difference in quality of life, mood, or cognitive function (quality of life: mean difference (MD) 0, 95% CI -0.03 to 0.03; 2 RCTs, 2349 participants; mood: MD 0.30, 95% CI -1.98 to 2.57; 2 RCTs, 2349 participants; cognitive function: MD -0.37, 95% CI -1.40 to 0.66; 1 RCTs, 2325 participants; all high-certainty evidence). Platelet transfusion likely increases death/dependence by day 90 compared to open control for antiplatelet-associated ICH (RR 1.29, 95% CI 1.04 to 1.61; 1 RCT, 190 participants; moderate-certainty evidence). We found little to no difference in ICH expansion between groups (RR 1.32, 95% CI 0.91 to 1.92; 1 RCT, 153 participants; moderate-certainty evidence). There was little to no difference in all serious adverse events and death from any cause between groups (all serious adverse events: RR 1.46, 95% CI 0.98 to 2.16; 1 RCT, 190 participants; death from any cause: RR 1.42, 95% CI 0.88 to 2.28; 1 RCT, 190 participants; both moderate-certainty evidence). For PCC versus FFP for anticoagulant-associated ICH, the evidence was very uncertain about the effect on death/dependence by day 90, ICH expansion, all serious adverse events, and death from any cause between groups (death/dependence by day 90: RR 1.21, 95% CI 0.76 to 1.90; 1 RCT, 37 participants; ICH expansion: RR 0.54, 95% CI 0.23 to 1.22; 1 RCT, 36 participants; all serious adverse events: RR 0.27, 95% CI 0.02 to 3.74; 1 RCT, 5 participants; death from any cause: RR 0.49, 95% CI 0.16 to 1.56; 2 RCTs, 42 participants; all very low-certainty evidence). In this updated Cochrane Review including 20 RCTs involving 4652 participants, rFVIIa likely results in little to no difference in reducing death or dependence after spontaneous ICH with or without surgery; antifibrinolytic drugs result in little to no difference in reducing death or dependence after spontaneous ICH, but result in a slight reduction in ICH expansion within 24 hours; platelet transfusion likely increases death or dependence after antiplatelet-associated ICH; and the evidence is very uncertain about the effect of PCC compared to FFP on death or dependence after anticoagulant-associated ICH. Thirteen RCTs are ongoing and are likely to increase the certainty of the estimates of treatment effect.
Abstract Summary: Doctors wanted to see if certain medicines could help adults who had a type of brain bleed that happens suddenly, without an injury. They looked at studies where patients got either the medicine being tested or a fake medicine (placebo) or no extra treatment. They wanted to know if these medicines could stop the bleeding from getting worse and help patients get better.
They found 20 studies with 4,652 patients and looked at different medicines. Some studies tested a medicine called rFVIIa, but it didn't really help patients avoid death or serious health problems. Another medicine, called antifibrinolytic drugs, didn't change the chances of dying or having serious health problems either, but it did help a little to stop the bleeding from getting worse. Giving patients platelet transfusions seemed to make things worse, not better. They also looked at a treatment called PCC compared to another one called FFP, but they weren't sure if it was helpful or not.
The doctors said that more studies are being done, and those might give clearer answers about how to help people with this kind of brain bleed.

Promoting transportation safety in adolescence: the drivingly randomized controlled trial.

Abstract: The impact of young drivers' motor vehicle crashes (MVC) is substantial, with young drivers constituting only 14% of the US population, but contributing to 30% of all fatal and nonfatal injuries due to MVCs and 35% ($25 billion) of the all medical and lost productivity costs. The current best-practice policy approach, Graduated Driver Licensing (GDL) programs, are effective primarily by delaying licensure and restricting crash opportunity. There is a critical need for interventions that target families to complement GDL. Consequently, we will determine if a comprehensive parent-teen intervention, the Drivingly Program, reduces teens' risk for a police-reported MVC in the first 12 months of licensure. Drivingly is based on strong preliminary data and targets multiple risk and protective factors by delivering intervention content to teens, and their parents, at the learner and early independent licensing phases. Eligible participants are aged 16-17.33 years of age, have a learner's permit in Pennsylvania, have practiced no more than 10 h, and have at least one parent/caregiver supervising. Participants are recruited from the general community and through the Children's Hospital of Philadelphia's Recruitment Enhancement Core. Teen-parent dyads are randomized 1:1 to Drivingly or usual practice control group. Drivingly participants receive access to an online curriculum which has 16 lessons for parents and 13 for teens and an online logbook; website usage is tracked. Parents receive two, brief, psychoeducational sessions with a trained health coach and teens receive an on-road driving intervention and feedback session after 4.5 months in the study and access to DriverZed, the AAA Foundation's online hazard training program. Teens complete surveys at baseline, 3 months post-baseline, at licensure, 3months post-licensure, 6 months post-licensure, and 12 months post-licensure. Parents complete surveys at baseline, 3 months post-baseline, and at teen licensure. The primary end-point is police-reported MVCs within the first 12 months of licensure; crash data are provided by the Pennsylvania Department of Transportation. Most evaluations of teen driver safety programs have significant methodological limitations including lack of random assignment, insufficient statistical power, and reliance on self-reported MVCs instead of police reports. Results will identify pragmatic and sustainable solutions for MVC prevention in adolescence. ClinicalTrials.gov # NCT03639753.
Abstract Summary: Scientists are studying a new program called Drivingly to see if it helps young drivers have fewer car crashes. Young drivers have a lot of crashes, which can hurt people and cost a lot of money. The Drivingly program teaches teens and their parents how to be safer on the road. Teens and their parents who are learning to drive in Pennsylvania can join the study. They get special lessons online, parents talk to a coach, and teens practice driving with an expert. The researchers will see if the teens who do the program have fewer crashes reported by the police in their first year of driving. This study is important because it could help us find better ways to keep young drivers safe.

National survey of patient symptoms and therapies among 707 women with a lipedema phenotype in the United States.
Vasc Med.
2024 Feb;
29(1):36-41.
Abstract: National survey data exploring the patient experience with lipedema are lacking. We conducted national surveys from 2016 to 2022 of women with lipedema as well as female controls. Surveys collected information on symptomatology, pain, and therapies. We performed logistic regression comparing symptoms among those with lipedema versus controls adjusting for age and BMI. A total of 707 women with lipedema and 216 controls completed the surveys. Those with lipedema had a mean age of 48.6 years and mean BMI of 40.9 kg/m. Lipedema symptom onset occurred frequently at puberty (48.0%) or pregnancy (41.2%). Compared to controls, women with lipedema were more likely to report leg swelling in heat (odds ratio [OR], 66.82; 95% CI, 33.04-135.12; < 0.0001), easy bruising (OR, 26.23; 95% CI, 15.58-44.17; < 0.0001), altered gait (OR, 15.54; 95% CI, 7.58-31.96; < 0.0001), flu-like symptoms (OR, 12.99; 95% CI, 4.27-39.49; < 0.0001), joint hypermobility (OR, 12.88; 95% CI, 6.68-24.81; < 0.0001), cool skin (OR, 12.21; 95% CI, 5.20-28.69; < 0.0001), varicose veins (OR, 11.29; 95% CI, 6.71-18.99; < 0.0001), and fatigue (OR, 9.59; 95% CI, 6.10-15.09; < 0.0001). Additionally, 70.3% had upper arm involvement, 21.2% reported foot swelling, and 16.6% reported foot pain. Most (52.2%) reported no symptom improvement with diet or exercise. Common therapies used included compression therapy (45.0%), gastric bypass (15.7%), and lower-extremity liposuction (14.0%). In a large, national, symptom survey, women with lipedema reported excess pain, swelling, and fat in the legs along with numerous symptoms beyond those classically described. Symptom responses to common therapies remain understudied.
Abstract Summary: Scientists did a big study from 2016 to 2022 to learn about a condition called lipedema that affects women. Lipedema can make legs swell and feel painful. They asked 707 women with lipedema and 216 women without it about their symptoms, pain, and what treatments they tried. They found that women with lipedema often started having symptoms when they hit puberty or during pregnancy. These women had more leg swelling, especially in the heat, bruised easily, walked differently, felt like they had the flu, had stretchy joints, cool skin, big veins, and felt very tired. Many also had arm problems, and some had swollen or painful feet. Diet and exercise didn't really help over half of them. Some treatments they used were special tight clothes to help with swelling, weight loss surgery, and surgery to remove fat from their legs. The study showed that women with lipedema have a lot of pain and other problems that aren't well-known, and we need to learn more about how to help them.

Immunomodulatory interventions for focal epilepsy.
The Cochrane database of systematic reviews (2023)

Immunomodulatory interventions for focal epilepsy.
Cochrane Database Syst Rev.
2023 Oct 16;
10(10):CD009945.
Abstract: This is an updated version of an original Cochrane Review published in 2013 (Walker 2013). Epilepsy is a common neurological disorder affecting 0.5% to 1% of the population. Pharmacological treatment remains the first choice to control epilepsy. However, up to 30% of people do not respond to drug treatment, and therefore do not achieve seizure remission. Experimental and clinical evidence supports a role for inflammatory pathway activation in the pathogenesis of epilepsy which, if effectively targeted by immunomodulatory interventions, highlights a potentially novel therapeutic strategy. To assess the efficacy and tolerability of immunomodulatory interventions on seizures, adverse effect profile, cognition, and quality of life, compared to placebo controls, when used as additional therapy for focal epilepsy in children and adults. For the latest update, we searched the following databases on 11 November 2021: Cochrane Register of Studies (CRS Web) and Medline (Ovid) 1946 to 10 November 2021. CRS Web includes randomised or quasi-randomised, controlled trials from PubMed, EMBASE, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform (ICTRP), the Cochrane Central Register of Controlled Trials (CENTRAL), and the Specialized Registers of Cochrane Review Groups including Epilepsy. We placed no language restrictions. We reviewed the bibliographies of retrieved studies to search for additional reports of relevant studies. Randomised placebo-controlled trials of add-on immunomodulatory drug interventions, in which an adequate method of concealment of randomisation was used. The studies were double-, single- or unblinded. Eligible participants were children (aged over 2 years) and adults with focal epilepsy. We used standard methodological procedures expected by the Cochrane Collaboration. We assessed the following outcomes. 1. 50% or greater reduction in seizure frequency. 2. Seizure freedom. 3. Treatment withdrawal for any reason. 4. Quality of life. 5. We used an intention-to-treat (ITT) population for all primary analyses, and we presented results as risk ratios (RRs) with 95% confidence intervals (95% Cl). We included three randomised, double-blind, placebo-controlled trials on a total of 172 participants. All trials included children and adults over two years of age with focal epilepsy. Treatment phases lasted six weeks and follow-up from six weeks to six months. One of the three included trials described an adequate method of concealment of randomisation, whilst the other two trials were rated as having an unclear risk of bias due to lack of reported information around study design. Effective blinding of studies was reported in all three trials. All analyses were by ITT. One trial was sponsored by the manufacturer of an immunomodulatory agent and therefore was at high risk of funding bias. Immunomodulatory interventions were significantly more effective than placebo in reducing seizure frequency (risk ratio (RR) 2.30, 95% confidence interval (CI) 1.15 to 4.60; 3 studies, 172 participants; moderate-certainty evidence). For treatment withdrawal, there was insufficient evidence to conclude that people were more likely to discontinue immunomodulatory intervention than placebo (RR 1.04, 95% CI 0.28 to 3.80; 3 studies, 172 participants; low-certainty evidence). The RR for adverse effects was 1.16 (95% CI 0.84 to 1.59; 1 study, 66 participants; low-certainty evidence). Certain adverse effects such as dizziness, headache, fatigue, and gastrointestinal disorders were more often associated with immunomodulatory interventions. There were little to no data on cognitive effects and quality of life. No important heterogeneity between studies was found for any of the outcomes. We judged the overall certainty of evidence (using the GRADE approach) as low to moderate due to potential attrition bias resulting from missing outcome data and imprecise results with wide confidence intervals. Immunomodulatory interventions as add-on treatment for children and adults with focal epilepsy appear to be effective in reducing seizure frequency. It is not possible to draw any conclusions about the tolerability of these agents in children and adults with epilepsy. Further randomised controlled trials are needed.
Abstract Summary: Scientists did a study to see if a new kind of medicine could help people with epilepsy, a brain problem that causes seizures. Some people with epilepsy don't get better with regular medicine, so the scientists wanted to see if medicines that change the immune system could help. They looked at three studies with 172 people who had a type of epilepsy that starts in one part of the brain. The new medicine seemed to help reduce seizures better than a fake medicine with no active ingredients. But they weren't sure if people would stop taking the new medicine because of side effects, like feeling dizzy or having a stomachache. They also didn't know if it would make people's thinking skills or how they felt about life any better. The scientists think more studies are needed to be sure if this new medicine is good for people with epilepsy.

Abstract: To determine if patients that develop lingering neurologic symptoms of fatigue and "brain fog" after initial recovery from coronavirus disease 2019 (COVID-19) have persistent low growth hormone (GH) secretion as seen in other conditions with similar symptom etiology. In this case-control observational pilot study, patients reporting lingering neurologic post-acute sequelae of SARS-CoV-2 (PASC, n = 10) symptoms at least 6 months after initial infection were compared to patients that recovered from COVID-19 without lingering symptoms (non-PASC, n = 13). We compared basic blood chemistry and select metabolites, lipids, hormones, inflammatory markers, and vitamins between groups. PASC and non-PASC subjects were tested for neurocognition and GH secretion, and given questionnaires to assess symptom severity. PASC subjects were also tested for glucose tolerance and adrenal function. PASC subjects reported significantly worse fatigue, sleep quality, depression, quality of life, and gastrointestinal discomfort compared to non-PASC. Although PASC subjects self-reported poor mental resilience, cognitive testing did not reveal significant differences between groups. Neurologic PASC symptoms were not linked to inflammatory markers or adrenal insufficiency, but were associated with reduced growth hormone secretion. Neurologic PASC symptoms are associated with gastrointestinal discomfort and persistent disruption of GH secretion following recovery from acute COVID-19. (www. gov; NCT04860869).
Abstract Summary: Scientists wanted to find out if people who still felt very tired and had trouble thinking clearly long after getting better from COVID-19 might not have enough of a body chemical called growth hormone. They looked at 10 people who had these problems and compared them to 13 people who got better without these issues. They checked their blood for different things like sugar, fat, hormones, signs of swelling, and vitamins. They also asked them questions and did tests to see how well their brains worked.
The study found that the people with lasting tiredness and brain fog felt worse overall, slept poorly, felt sad, and had tummy troubles compared to those who got better without these problems. Even though they felt like their thinking wasn't good, the tests didn't show a big difference between the two groups. The tired group didn't have signs of swelling or problems with another body chemical called adrenaline, but they did have less growth hormone.
This study is important because it shows that people who don't feel well for a long time after COVID-19 might have a problem with their growth hormone, and this could be why they have stomach issues and feel so tired.

Pharmacological intervention for irritability, aggression, and self-injury in autism spectrum disorder (ASD).
Cochrane Database Syst Rev.
2023 Oct 9;
10(10):CD011769.
Abstract: Pharmacological interventions are frequently used for people with autism spectrum disorder (ASD) to manage behaviours of concern, including irritability, aggression, and self-injury. Some pharmacological interventions might help treat some behaviours of concern, but can also have adverse effects (AEs). To assess the effectiveness and AEs of pharmacological interventions for managing the behaviours of irritability, aggression, and self-injury in ASD. We searched CENTRAL, MEDLINE, Embase, 11 other databases and two trials registers up to June 2022. We also searched reference lists of relevant studies, and contacted study authors, experts and pharmaceutical companies. We included randomised controlled trials of participants of any age with a clinical diagnosis of ASD, that compared any pharmacological intervention to an alternative drug, standard care, placebo, or wait-list control. We used standard Cochrane methods. Primary outcomes were behaviours of concern in ASD, (irritability, aggression and self-injury); and AEs. Secondary outcomes were quality of life, and tolerability and acceptability. Two review authors independently assessed each study for risk of bias, and used GRADE to judge the certainty of the evidence for each outcome. We included 131 studies involving 7014 participants in this review. We identified 26 studies as awaiting classification and 25 as ongoing. Most studies involved children (53 studies involved only children under 13 years), children and adolescents (37 studies), adolescents only (2 studies) children and adults (16 studies), or adults only (23 studies). All included studies compared a pharmacological intervention to a placebo or to another pharmacological intervention. Atypical antipsychotics versus placebo At short-term follow-up (up to 6 months), atypical antipsychotics probably reduce irritability compared to placebo (standardised mean difference (SMD) -0.90, 95% confidence interval (CI) -1.25 to -0.55, 12 studies, 973 participants; moderate-certainty evidence), which may indicate a large effect. However, there was no clear evidence of a difference in aggression between groups (SMD -0.44, 95% CI -0.89 to 0.01; 1 study, 77 participants; very low-certainty evidence). Atypical antipsychotics may also reduce self-injury (SMD -1.43, 95% CI -2.24 to -0.61; 1 study, 30 participants; low-certainty evidence), possibly indicating a large effect. There may be higher rates of neurological AEs (dizziness, fatigue, sedation, somnolence, and tremor) in the intervention group (low-certainty evidence), but there was no clear evidence of an effect on other neurological AEs. Increased appetite may be higher in the intervention group (low-certainty evidence), but we found no clear evidence of an effect on other metabolic AEs. There was no clear evidence of differences between groups in musculoskeletal or psychological AEs. Neurohormones versus placebo At short-term follow-up, neurohormones may have minimal to no clear effect on irritability when compared to placebo (SMD -0.18, 95% CI -0.37 to -0.00; 8 studies; 466 participants; very low-certainty evidence), although the evidence is very uncertain. No data were reported for aggression or self -injury. Neurohormones may reduce the risk of headaches slightly in the intervention group, although the evidence is very uncertain. There was no clear evidence of an effect of neurohormones on any other neurological AEs, nor on any psychological, metabolic, or musculoskeletal AEs (low- and very low-certainty evidence). Attention-deficit hyperactivity disorder (ADHD)-related medications versus placebo At short-term follow-up, ADHD-related medications may reduce irritability slightly (SMD -0.20, 95% CI -0.40 to -0.01; 10 studies, 400 participants; low-certainty evidence), which may indicate a small effect. However, there was no clear evidence that ADHD-related medications have an effect on self-injury (SMD -0.62, 95% CI -1.63 to 0.39; 1 study, 16 participants; very low-certainty evidence). No data were reported for aggression. Rates of neurological AEs (drowsiness, emotional AEs, fatigue, headache, insomnia, and irritability), metabolic AEs (decreased appetite) and psychological AEs (depression) may be higher in the intervention group, although the evidence is very uncertain (very low-certainty evidence). There was no evidence of a difference between groups for any other metabolic, neurological, or psychological AEs (very low-certainty evidence). No data were reported for musculoskeletal AEs. Antidepressants versus placebo At short-term follow-up, there was no clear evidence that antidepressants have an effect on irritability (SMD -0.06, 95% CI -0.30 to 0.18; 3 studies, 267 participants; low-certainty evidence). No data for aggression or self-injury were reported or could be included in the analysis. Rates of metabolic AEs (decreased energy) may be higher in participants receiving antidepressants (very low-certainty evidence), although no other metabolic AEs showed clear evidence of a difference. Rates of neurological AEs (decreased attention) and psychological AEs (impulsive behaviour and stereotypy) may also be higher in the intervention group (very low-certainty evidence) although the evidence is very uncertain. There was no clear evidence of any difference in the other metabolic, neurological, or psychological AEs (very low-certainty evidence), nor between groups in musculoskeletal AEs (very low-certainty evidence). Risk of bias We rated most of the studies across the four comparisons at unclear overall risk of bias due to having multiple domains rated as unclear, very few rated as low across all domains, and most having at least one domain rated as high risk of bias. Evidence suggests that atypical antipsychotics probably reduce irritability, ADHD-related medications may reduce irritability slightly, and neurohormones may have little to no effect on irritability in the short term in people with ASD. There was some evidence that atypical antipsychotics may reduce self-injury in the short term, although the evidence is uncertain. There was no clear evidence that antidepressants had an effect on irritability. There was also little to no difference in aggression between atypical antipsychotics and placebo, or self-injury between ADHD-related medications and placebo. However, there was some evidence that atypical antipsychotics may result in a large reduction in self-injury, although the evidence is uncertain. No data were reported (or could be used) for self-injury or aggression for neurohormones versus placebo. Studies reported a wide range of potential AEs. Atypical antipsychotics and ADHD-related medications in particular were associated with an increased risk of metabolic and neurological AEs, although the evidence is uncertain for atypical antipsychotics and very uncertain for ADHD-related medications. The other drug classes had minimal or no associated AEs.
Abstract Summary: Scientists did a big study to see if certain medicines can help people with autism calm down when they feel really upset or hurt themselves. They looked at lots of research and found 131 studies with 7014 people. They checked if the medicines were better than a pretend pill (placebo) or other treatments.
They found that some medicines called atypical antipsychotics might help a lot with getting less irritable, but they weren't sure if they helped with aggression or self-injury. These medicines might make people feel dizzy or hungry. Another kind of medicine for ADHD might help a little with irritability, but they didn't know if it helped with self-injury, and it might make people feel tired or have headaches. They also looked at neurohormones and antidepressants, but these didn't seem to help much, and they might make some people feel less energetic or pay less attention.
In the end, they think that atypical antipsychotics could really help with irritability and maybe self-injury, but all these medicines could have some side effects. They're not totally sure, though, because the studies weren't perfect. This information is important for doctors and people with autism to think about when choosing medicines.

Amyloid PET across the cognitive spectrum in former professional and college American football players: findings from the DIAGNOSE CTE Research Project.
Alzheimers Res Ther.
2023 Oct 5;
15(1):166.
Abstract: Exposure to repetitive head impacts (RHI) in American football players can lead to cognitive impairment and dementia due to neurodegenerative disease, particularly chronic traumatic encephalopathy (CTE). The pathognomonic lesion of CTE consists of perivascular aggregates of hyper-phosphorylated tau in neurons at the depths of cortical sulci. However, it is unclear whether exposure to RHI accelerates amyloid-β (Aβ) plaque formation and increases the risk for Alzheimer's disease (AD). Although the Aβ neuritic plaques characteristic of AD are observed in a minority of later-stage CTE cases, diffuse plaques are more common. This study examined whether former professional and college American football players, including those with cognitive impairment and dementia, have elevated neuritic Aβ plaque density, as measured by florbetapir PET. Regardless of cognitive and functional status, elevated levels of florbetapir uptake were not expected. We examined 237 men ages 45-74, including 119 former professional (PRO) and 60 former college (COL) football players, with and without cognitive impairment and dementia, and 58 same-age men without a history of contact sports or TBI (unexposed; UE) and who denied cognitive or behavioral symptoms at telephone screening. Former players were categorized into four diagnostic groups: normal cognition, subjective memory impairment, mild cognitive impairment, and dementia. Positive florbetapir PET was defined by cortical-cerebellar average SUVR of ≥ 1.10. Multivariable linear regression and analysis of covariance (ANCOVA) compared florbetapir average SUVR across diagnostic and exposure groups. Multivariable logistic regression compared florbetapir positivity. Race, education, age, and APOE4 were covariates. There were no diagnostic group differences either in florbetapir average SUVR or the proportion of elevated florbetapir uptake. Average SUVR means also did not differ between exposure groups: PRO-COL (p = 0.94, 95% C.I. = [- 0.033, 0.025]), PRO-UE (p = 0.40, 95% C.I. = [- 0.010, 0.029]), COL-UE (p = 0.36, 95% CI = [0.0004, 0.039]). Florbetapir was not significantly associated with years of football exposure, cognition, or daily functioning. Cognitive impairment in former American football players is not associated with PET imaging of neuritic Aβ plaque deposition. These findings are inconsistent with a neuropathological diagnosis of AD in individuals with substantial RHI exposure and have both clinical and medico-legal implications. NCT02798185.
Abstract Summary: Scientists wanted to see if playing American football, which can cause lots of hits to the head, might make players more likely to get a brain problem called Alzheimer's disease when they get older. Alzheimer's disease can make it hard for people to remember things and take care of themselves. The researchers used a special brain scan to look for signs of Alzheimer's in former professional and college football players, some of whom were having memory problems, and compared them to men who never played contact sports.
They checked 237 men between 45 and 74 years old. The brain scans did not show more signs of Alzheimer's in the football players, even in those who played a lot or had memory issues. This means that the memory problems in these football players might not be caused by Alzheimer's. This is important for doctors to know when they are trying to help players who have memory problems after many hits to the head. It also matters for legal reasons, like when players need to prove their health problems are because of football.

Abstract: Multicenter clinical trials play a critical role in the translational processes that enable new treatments to reach all people and improve public health. However, conducting multicenter randomized clinical trials (mRCT) presents challenges. The Trial Innovation Network (TIN), established in 2016 to partner with the Clinical and Translational Science Award (CTSA) Consortium of academic medical institutions in the implementation of mRCTs, consists of 3 Trial Innovation Centers (TICs) and 1 Recruitment Innovation Center (RIC). This unique partnership has aimed to address critical roadblocks that impede the design and conduct of mRCTs, in expectation of accelerating the translation of novel interventions to clinical practice. The TIN's challenges and achievements are described in this article, along with examples of innovative resources and processes that may serve as useful models for other clinical trial networks providing operational and recruitment support. The TIN has successfully integrated more than 60 CTSA institution program hubs into a functional network for mRCT implementation and optimization. A unique support system for investigators has been created that includes the development and deployment of novel tools, operational and recruitment services, consultation models, and rapid communication pathways designed to reduce delays in trial start-up, enhance recruitment, improve engagement of diverse research participants and communities, and streamline processes that improve the quality, efficiency, and conduct of mRCTs. These resources and processes span the clinical trial spectrum and enable the TICs and RIC to serve as coordinating centers, data centers, and recruitment specialists to assist trials across the National Institutes of Health and other agencies. The TIN's impact has been demonstrated through its response to both historical operational challenges and emerging public health emergencies, including the national opioid public health crisis and the COVID-19 pandemic. The TIN has worked to reduce barriers to implementing mRCTs and to improve mRCT processes and operations by providing needed clinical trial infrastructure and resources to CTSA investigators. These resources have been instrumental in more quickly and efficiently translating research discoveries into beneficial patient treatments.
Abstract Summary: Scientists do big studies called multicenter clinical trials to test new treatments and help everyone's health. These studies can be hard to do, so in 2016, a group called the Trial Innovation Network (TIN) started helping by working with lots of medical schools. TIN helps solve problems that make these studies slow or difficult. They've made tools and ways to talk quickly so that studies can start faster, include people from different places, and work better.
TIN has connected over 60 places into a team that makes these big studies better and faster. They help with planning, finding people to join the studies, and sharing information. This has been really important for dealing with big health problems like the opioid crisis and COVID-19. Because of TIN, new treatments can get to patients quicker, which is great for everyone's health.

Psychosocial interventions for survivors of rape and sexual assault experienced during adulthood.

Abstract: Exposure to rape, sexual assault and sexual abuse has lifelong impacts for mental health and well-being. Prolonged Exposure (PE), Cognitive Processing Therapy (CPT) and Eye Movement Desensitisation and Reprocessing (EMDR) are among the most common interventions offered to survivors to alleviate post-traumatic stress disorder (PTSD) and other psychological impacts. Beyond such trauma-focused cognitive and behavioural approaches, there is a range of low-intensity interventions along with new and emerging non-exposure based approaches (trauma-sensitive yoga, Reconsolidation of Traumatic Memories and Lifespan Integration). This review presents a timely assessment of international evidence on any type of psychosocial intervention offered to individuals who experienced rape, sexual assault or sexual abuse as adults. To assess the effects of psychosocial interventions on mental health and well-being for survivors of rape, sexual assault or sexual abuse experienced during adulthood. In January 2022, we searched CENTRAL, MEDLINE, Embase, 12 other databases and three trials registers. We also checked reference lists of included studies, contacted authors and experts, and ran forward citation searches. Any study that allocated individuals or clusters of individuals by a random or quasi-random method to a psychosocial intervention that promoted recovery and healing following exposure to rape, sexual assault or sexual abuse in those aged 18 years and above compared with no or minimal intervention, usual care, wait-list, pharmacological only or active comparison(s). We classified psychosocial interventions according to Cochrane Common Mental Disorders Group's psychological therapies list. We used the standard methodological procedures expected by Cochrane. We included 36 studies (1991 to 2021) with 3992 participants randomly assigned to 60 experimental groups (3014; 76%) and 23 inactive comparator conditions (978, 24%). The experimental groups consisted of: 32 Cognitive Behavioural Therapy (CBT); 10 behavioural interventions; three integrative therapies; three humanist; five other psychologically oriented interventions; and seven other psychosocial interventions. Delivery involved 1 to 20 (median 11) sessions of traditional face-to-face (41) or other individual formats (four); groups (nine); or involved computer-only interaction (six). Most studies were conducted in the USA (n = 26); two were from South Africa; two from the Democratic Republic of the Congo; with single studies from Australia, Canada, the Netherlands, Spain, Sweden and the UK. Five studies did not disclose a funding source, and all disclosed sources were public funding. Participants were invited from a range of settings: from the community, through the media, from universities and in places where people might seek help for their mental health (e.g. war veterans), in the aftermath of sexual trauma (sexual assault centres and emergency departments) or for problems that accompany the experience of sexual violence (e.g. sexual health/primary care clinics). Participants randomised were 99% women (3965 participants) with just 27 men. Half were Black, African or African-American (1889 participants); 40% White/Caucasian (1530 participants); and 10% represented a range of other ethnic backgrounds (396 participants). The weighted mean age was 35.9 years (standard deviation (SD) 9.6). Eighty-two per cent had experienced rape or sexual assault in adulthood (3260/3992). Twenty-two studies (61%) required fulfilling a measured PTSD diagnostic threshold for inclusion; however, 94% of participants (2239/2370) were reported as having clinically relevant PTSD symptoms at entry. The comparison of psychosocial interventions with inactive controls detected that there may be a beneficial effect at post-treatment favouring psychosocial interventions in reducing PTSD (standardised mean difference (SMD) -0.83, 95% confidence interval (CI) -1.22 to -0.44; 16 studies, 1130 participants; low-certainty evidence; large effect size based on Cohen's D); and depression (SMD -0.82, 95% CI -1.17 to -0.48; 12 studies, 901 participants; low-certainty evidence; large effect size). Psychosocial interventions, however, may not increase the risk of dropout from treatment compared to controls, with a risk ratio of 0.85 (95% CI 0.51 to 1.44; 5 studies, 242 participants; low-certainty evidence). Seven of the 23 studies (with 801 participants) comparing a psychosocial intervention to an inactive control reported on adverse events, with 21 events indicated. Psychosocial interventions may not increase the risk of adverse events compared to controls, with a risk ratio of 1.92 (95% CI 0.30 to 12.41; 6 studies; 622 participants; very low-certainty evidence). We conducted an assessment of risk of bias using the RoB 2 tool on a total of 49 reported results. A high risk of bias affected 43% of PTSD results; 59% for depression symptoms; 40% for treatment dropout; and one-third for adverse events. The greatest sources of bias were problems with randomisation and missing outcome data. Heterogeneity was also high, ranging from I = 30% (adverse events) to I = 87% (PTSD). Our review suggests that survivors of rape, sexual violence and sexual abuse during adulthood may experience a large reduction in post-treatment PTSD symptoms and depressive symptoms after experiencing a psychosocial intervention, relative to comparison groups. Psychosocial interventions do not seem to increase dropout from treatment or adverse events/effects compared to controls. However, the number of dropouts and study attrition were generally high, potentially missing harms of exposure to interventions and/or research participation. Also, the differential effects of specific intervention types needs further investigation. We conclude that a range of behavioural and CBT-based interventions may improve the mental health of survivors of rape, sexual assault and sexual abuse in the short term. Therefore, the needs and preferences of individuals must be considered in selecting suitable approaches to therapy and support. The primary outcome in this review focused on the post-treatment period and the question about whether benefits are sustained over time persists. However, attaining such evidence from studies that lack an active comparison may be impractical and even unethical. Thus, we suggest that studies undertake head-to-head comparisons of different intervention types; in particular, of novel, emerging therapies, with one-year plus follow-up periods. Additionally, researchers should focus on the therapeutic benefits and costs for subpopulations such as male survivors and those living with complex PTSD.
Abstract Summary: Scientists did a big study to see how different kinds of talking and activity therapies help adults who have been hurt by sexual violence. They looked at many studies from all over the world and found that these therapies can really help reduce bad feelings and stress. Most of the people in the studies were women, and the therapies included things like talking about feelings, learning how to deal with tough emotions, and doing special exercises like yoga. The therapies seemed to work well right after treatment, but the scientists aren't sure if they help in the long run. They think more research is needed, especially to see if these therapies help men and people with very bad stress from the violence. They also want to compare different kinds of therapies to find out which ones are the best.

Influences of sex chromosome aneuploidy on height, weight, and body mass index in human childhood and adolescence.
Am J Med Genet A.
2024 Feb;
194(2):150-159.
Abstract: Sex chromosome aneuploidies (SCAs) are collectively common conditions caused by carriage of a sex chromosome dosage other than XX for females and XY for males. Increases in sex chromosome dosage (SCD) have been shown to have an inverted-U association with height, but we lack combined studies of SCA effects on height and weight, and it is not known if any such effects vary with age. Here, we study norm-derived height and weight z-scores in 177 youth spanning 8 SCA karyotypes (XXX, XXY, XYY, XXXX, XXXY, XXYY, XXXXX, and XXXXY). We replicate a previously described inverted-U association between mounting SCD and height, and further show that there is also a muted version of this effect for weight: both phenotypes are elevated until SCD reaches 4 for females and 5 for males but decrease thereafter. We next use 266 longitudinal measures available from a subset of karyotypes (XXX, XXY, XYY, and XXYY) to show that mean height in these SCAs diverges further from norms with increasing age. As weight does not diverge from norms with increasing age, BMI decreases with increasing age. These findings extend our understanding of growth as an important clinical outcome in SCA, and as a key context for known effects of SCA on diverse organ systems that scale with body size.
Abstract Summary: Scientists studied how having extra sex chromosomes affects kids' height and weight. Usually, girls have two X chromosomes and boys have one X and one Y. But sometimes, kids have extra X or Y chromosomes, which can change their growth. The researchers looked at 177 kids with different combinations of extra sex chromosomes. They found that kids with a certain number of extra chromosomes were taller and heavier, but if they had even more, they started to be shorter and lighter. They also checked 177 kids over time and noticed that as these kids got older, they kept growing taller compared to other kids their age, but their weight didn't increase as much, so they became less heavy for their height. This study helps us understand how having extra sex chromosomes can affect kids' growth, which is important for doctors to know when taking care of these kids.

Abstract: Plasma levels of the metabolite alpha-aminoadipic acid (2-AAA) have been associated with risk of type 2 diabetes (T2D) and atherosclerosis. However, little is known about the relationship of 2-AAA to other cardiometabolic risk markers in pre-disease states, or in the setting of comorbid disease. We measured circulating 2-AAA using two methods in 1) a sample of 261 healthy individuals (2-AAA Study), and 2) in a sample of 134 persons comprising 110 individuals with treated HIV, with or without T2D, a population at high risk of metabolic disease and cardiovascular events despite suppression of circulating virus, and 24 individuals with T2D without HIV (HATIM Study). We examined associations between plasma 2-AAA and markers of cardiometabolic health within each cohort. We observed differences in 2-AAA by sex and race in both cohorts, with higher levels observed in men compared with women, and in Asian compared with Black or white individuals (P<0.05). There was no significant difference in 2-AAA by HIV status within individuals with T2D in the HATIM Study. We confirmed associations between 2-AAA and dyslipidemia in both cohorts, where high 2-AAA associated with low HDL cholesterol (P<0.001) and high triglycerides (P<0.05). As expected, within the cohort of people with HIV, 2-AAA was higher in the setting of T2D compared to pre-diabetes or normoglycemia (P<0.001). 2-AAA was positively associated with body mass index (BMI) in the 2-AAA Study, and with waist circumference and measures of visceral fat volume in HATIM (all P<0.05). Further, 2-AAA associated with increased liver fat in persons with HIV (P<0.001). Our study confirms 2-AAA as a marker of cardiometabolic risk in both healthy individuals and those at high cardiometabolic risk, reveals relationships with adiposity and hepatic steatosis, and highlights important differences by sex and race. Further studies are warranted to establish molecular mechanisms linking 2-AAA to disease in other high-risk populations.
Abstract Summary: Scientists did a study to learn more about a chemical in the blood called alpha-aminoadipic acid (2-AAA) and how it might be connected to heart disease and diabetes. They checked the levels of 2-AAA in two groups of people: one group was healthy, and the other group had either HIV or diabetes, which can make heart problems more likely. They found that men and Asian people had more 2-AAA than women and people of other races. Also, people with higher 2-AAA often had unhealthy cholesterol and fat levels. In people with HIV, having diabetes also meant having more 2-AAA. The study showed that 2-AAA could be a sign that someone might have heart or weight problems. The scientists think more research is needed to understand why 2-AAA is linked to these health issues in different kinds of people.

24(7):1386-1397.
Abstract: Emergency responders face challenges in arriving timely to administer naloxone in opioid overdoses. Therefore, interest in having lay citizens administer naloxone nasal spray has emerged. These citizens, however, must be recruited and trained, and be in proximity to the overdose. This study aimed to develop the Opioid Rapid Response System (ORRS) to meet this need by developing a system to recruit and train citizen responders and evaluate outcomes in a randomized clinical trial. ORRS recruitment messages and training platform were developed iteratively and then outcomes for each were evaluated in a randomized, unblinded two-arm waitlist-controlled trial. ORRS was field tested in 5 Indiana counties, recruiting adult citizen responders (age 18 or older) who did not self-identity as a certified first responder. Participants were recruited using either personal or communal messages and then randomly assigned to online naloxone training and waitlisted-control conditions. Pre- and post-surveys were administered online to measure the exposure to recruitment messages and training effects on knowledge of opioid overdose, confidence responding, concerns about responding, and intent to respond. Of the 220 randomized participants (114 training, 106 waitlisted-control), 140 were analyzed (59 training, 81 waitlisted-control). Recruited participants more frequently identified with communal appeal than with the personal appeal (chi-square = 53.5; p < 0.0001). Between-group differences for intervention effects were significant for knowledge of overdose signs (Cohen's d = 1.17), knowledge of overdose management (d = 1.72), self-efficacy (d = 1.39), and concerns (d = 1.31), but not for intent (d = 0.17), which suffered from a ceiling effect. ORRS provides stronger support for efficacy than that reported for other training interventions and the digital modality eases rapid dissemination.Trial Registration: NCT04589676.
Abstract Summary: Scientists did a study to help regular people learn how to use a special nose spray to save someone who has taken too much of a strong pain medicine called opioids. They made a program called the Opioid Rapid Response System (ORRS) to teach people and see if it works. They tested it in Indiana with adults who weren't already trained to help in emergencies. They found out that people liked to join the program to help their community more than just for personal reasons. After training, these people knew more about how to tell if someone has taken too many opioids and felt more sure they could help. They also weren't as worried about helping, but their willingness to help didn't change much because they already wanted to help a lot. This study shows that teaching people online is a good way to quickly spread the knowledge on how to save lives with the nose spray.

Abstract: Insulin resistance (IR) is a pathophysiologic hallmark of type 2 diabetes and associated with the presence of chronic kidney disease (CKD). Experimental studies suggest that endothelin-1 increases IR. We assessed the association between IR and cardio-renal outcomes and the effect of the selective endothelin receptor antagonist atrasentan on IR in patients with type 2 diabetes and CKD. We used data from the RADAR and SONAR trials that recruited participants with type 2 diabetes and CKD [eGFR 25-75 mL/min/1.73 m², urine albumin-to-creatinine ratio of 300-5000 mg/g]. IR was calculated using the homeostatic model assessment (HOMA-IR). The association between HOMA-IR and the pre-specified cardio-renal outcomes was assessed using multivariable Cox proportional hazards regression, and effects of atrasentan on HOMA-IR by a linear mixed effect model. In the SONAR trial, each log-unit increase in HOMA-IR was associated with an increased risk of the composite cardio-renal outcome [hazard ratio 1.32 (95%CI 1.09,1.60; p = 0.004)], kidney outcome [hazard ratio 1.30 (95%CI 1.00,1.68; p-value = 0.048)], and the kidney or all-cause mortality outcome [hazard ratio 1.25 (95%CI 1.01,1.55; p-value = 0.037)]. After 12 weeks treatment in the RADAR trial (N = 123), atrasentan 0.75 mg/day and 1.25 mg/day compared to placebo reduced HOMA-IR by 19.1 (95%CI -17.4, 44.3) and 26.7% (95%CI -6.4, 49.5), respectively. In the SONAR trial (N = 1914), atrasentan 0.75 mg/day compared to placebo reduced HOMA-IR by 9.6% (95%CI 0.6, 17.9). More severe IR is associated with increased risk of cardio-renal outcomes. The endothelin receptor antagonist atrasentan reduced IR. RADAR trial (Reducing Residual Albuminuria in Subjects With Diabetes and Nephropathy With AtRasentan): NCT01356849. SONAR trial (The Study Of Diabetic Nephropathy With AtRasentan) NCT01858532.
Abstract Summary: Scientists did a study to see if a medicine called atrasentan can help people with type 2 diabetes and kidney disease by lowering insulin resistance (IR), which is when the body doesn't use insulin well. Insulin is important because it helps sugar get into cells for energy. They looked at data from two big studies with people who have diabetes and kidney problems. They found that when IR was higher, people had more heart and kidney problems. They also discovered that taking atrasentan made IR lower. This is good news because it might mean that atrasentan can help protect the hearts and kidneys of people with diabetes.

Changes in subcutaneous white adipose tissue cellular composition and molecular programs underlie glucose intolerance in persons with HIV.

Abstract: Subcutaneous adipose tissue (SAT) is a critical regulator of systemic metabolic homeostasis. Persons with HIV (PWH) have an increased risk of metabolic diseases and significant alterations in the SAT immune environment compared with the general population. We generated a comprehensive single-cell multi-omic SAT atlas to characterize cellular compositional and transcriptional changes in 59 PWH across a spectrum of metabolic health. Glucose intolerance was associated with increased lipid-associated macrophages, CD4 and CD8 T effector memory cells, and decreased perivascular macrophages. We observed a coordinated intercellular regulatory program which enriched for genes related to inflammation and lipid-processing across multiple cell types as glucose intolerance increased. Increased CD4 effector memory tissue-resident cells most strongly associated with altered expression of adipocyte genes critical for lipid metabolism and cellular regulation. Intercellular communication analysis demonstrated enhanced pro-inflammatory and pro-fibrotic signaling between immune cells and stromal cells in PWH with glucose intolerance compared with non-diabetic PWH. Lastly, while cell type-specific gene expression among PWH with diabetes was globally similar to HIV-negative individuals with diabetes, we observed substantially divergent intercellular communication pathways. These findings suggest a central role of tissue-resident immune cells in regulating SAT inflammation among PWH with metabolic disease, and underscore unique mechanisms that may converge to promote metabolic disease.
Abstract Summary: Scientists studied how body fat works in people with HIV because they have a higher chance of getting diseases like diabetes. They looked at fat cells from 59 people with HIV who had different health levels. They found that people with trouble processing sugar had more fat-related immune cells and memory cells that fight infections. These cells were also talking to each other in a way that could lead to more inflammation and scarring. Even though people with HIV and diabetes had similar changes in their fat cells as people without HIV, the way their cells communicated was different. This research helps us understand that immune cells in fat are important in controlling inflammation in people with HIV who have diseases like diabetes.

Abstract: To assess the effects of canagliflozin on clinical outcomes and intermediate markers across population-specific body mass index (BMI) categories in the CANVAS Program and CREDENCE trial. Individual participant data were pooled and analysed in subgroups according to population-specific BMI. The main outcomes of interest were: major adverse cardiovascular events (MACE, a composite of nonfatal myocardial infarction, nonfatal stroke or cardiovascular death); composite renal outcome; and changes in systolic blood pressure (SBP), body weight, albuminuria and estimated glomerular filtration rate (eGFR) slope. Cox proportional hazards models and mixed-effect models were used. A total of 14 520 participants were included, of whom 9378 (65%) had obesity. Overall, canagliflozin reduced the risk of MACE (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.75 to 0.93) with no heterogeneity of treatment effect across BMI subgroups (P = 0.76). Similarly, canagliflozin reduced composite renal outcomes (HR 0.75, 95% CI 0.66 to 0.84) with no heterogeneity across subgroups observed (P = 0.72). The effects of canagliflozin on body weight and SBP differed across BMI subgroups (P <0.01 and 0.04, respectively) but were consistent for albuminuria (P = 0.60). Chronic eGFR slope with canagliflozin treatment was consistent across subgroups (P >0.95). The cardiovascular and renal benefits of canagliflozin and its safety profile were consistent across population-specific BMI subgroups for adults in the CANVAS Program and CREDENCE trial.
Abstract Summary: Scientists did a study to see if a medicine called canagliflozin helps adults with different body sizes stay healthy. They looked at over 14,000 people, many of whom were overweight, to see if the medicine could prevent heart problems, help kidneys work better, and control blood pressure and weight. They found that canagliflozin was good at reducing the risk of heart issues and helping kidneys, no matter the person's body size. It also helped people lose weight and lower their blood pressure, but the amount varied for different body sizes. This study shows that canagliflozin is safe and works well for adults with different body sizes to keep their hearts and kidneys healthy.

Post hoc analysis of the SONAR trial indicates that the endothelin receptor antagonist atrasentan is associated with less pain in patients with type 2 diabetes and chronic kidney disease.
Kidney Int.
2023 Dec;
104(6):1219-1226.
Abstract: Pain is prevalent among patients with diabetes and chronic kidney disease (CKD). The management of chronic pain in these patients is limited by nephrotoxicity of commonly used drugs including non-steroidal anti-inflammatory drugs (NSAIDs) and opioids. Since previous studies implicated endothelin-1 in pain nociception, our post hoc analysis of the SONAR trial assessed the association between the endothelin receptor antagonist atrasentan and pain and prescription of analgesics. SONAR was a randomized, double-blind, placebo-controlled clinical trial that recruited participants with type 2 diabetes and CKD (estimated glomerular filtration rate 25-75 ml/min/1.73 m; urinary albumin-to-creatinine ratio 300-5000 mg/g). Participants were randomized to receive atrasentan or placebo (1834 each arm). The main outcome was pain-related adverse events (AEs) reported by investigators. We applied Cox regression to assess the effect of atrasentan compared to placebo on the risk of the first reported pain-related AE and, secondly, first prescription of analgesics. We used the Anderson-Gill method to assess effects on all (first and subsequent) pain-related AEs. During 2.2-year median follow-up, 1183 pain-related AEs occurred. Rates for the first pain-related event were 138.2 and 170.2 per 1000 person-years in the atrasentan and placebo group respectively (hazard ratio 0.82 [95% confidence interval 0.72-0.93]). Atrasentan also reduced the rate of all (first and subsequent) pain-related AEs (rate ratio 0.80 [0.70-0.91]). These findings were similar after accounting for competing risk of death (sub-hazard ratio 0.81 [0.71-0.92]). Patients treated with atrasentan initiated fewer analgesics including NSAIDs and opioids compared to placebo during follow-up (hazard ratio = 0.72 [0.60-0.88]). Thus, atrasentan was associated with reduced pain-related events and pain-related use of analgesics in carefully selected patients with type 2 diabetes and CKD.
Abstract Summary: Doctors did a study to see if a medicine called atrasentan could help with pain in people who have diabetes and kidney problems. They gave some people atrasentan and others a fake pill (placebo) to compare what happened. They found that the people who took atrasentan had less pain and didn't need as many painkillers, including common ones that can hurt their kidneys. This is good news because it means there might be a safer way for these patients to feel better without using medicines that can make their kidney problems worse.

Changes in Metabolic Parameters and Body Weight in Patients With Prediabetes Treated With Adjunctive Brexpiprazole for Major Depressive Disorder: Pooled Analysis of Short- and Long-Term Clinical Studies.
J Clin Psychiatry.

84(5):.
Abstract: Certain atypical antipsychotics, while efficacious as adjunctive treatments in major depressive disorder (MDD), are associated with metabolic adverse effects and weight gain. This analysis determined the effect of adjunctive brexpiprazole on metabolic parameters and body weight in adults with MDD and prediabetes (ie, at risk of developing diabetes) based on pooled data from 3 short-term studies and 1 long-term study. The short-term studies were 6-week, randomized, double-blind, placebo-controlled studies of adjunctive oral brexpiprazole 1-3 mg/d in outpatients with MDD ( criteria) and inadequate response to antidepressant treatment, conducted between June 2011 and May 2016. The long-term study was a 26- to 52-week, open-label extension study conducted between October 2011 and May 2017. was defined based on fasting serum glucose and glycated hemoglobin (HbA1c) levels. Shifts in diabetes status and shifts/changes in fasting metabolic parameters and body weight were determined. Most patients receiving adjunctive brexpiprazole maintained their baseline diabetes status in the short term (568/751; 75.6%) and long term (1,919/2,746; 69.9%). The incidence of categorical shifts in fasting metabolic parameters generally did not differ between treatment groups or between prediabetes and non-diabetes subgroups. Mean changes from baseline in metabolic parameters were small in the short term (all < 5 mg/dL) and long term (all < 6 mg/dL, except < 20 mg/dL for triglycerides). Moderate weight gain was observed in the short term (1.5 kg) and long term (3.4-4.1 kg). Adjunctive brexpiprazole had a limited impact on the metabolic profile of patients with MDD, regardless of diabetes status (prediabetes/non-diabetes). Data used in this post hoc analysis came from studies with ClinicalTrials.gov identifiers NCT01360645, NCT01360632, NCT02196506, and NCT01360866.
Abstract Summary: Scientists looked at how a medicine called brexpiprazole affects people with depression and a higher chance of getting diabetes when it's added to their usual treatment. They used information from three studies that lasted 6 weeks and one study that lasted up to a year. They wanted to see if the medicine changed people's blood sugar levels, diabetes status, or weight.
They found that most people who took brexpiprazole didn't have big changes in their blood sugar or diabetes status in both the short and long term. People did gain a little bit of weight, but not too much. This means that brexpiprazole doesn't have a big effect on blood sugar or diabetes but can cause some weight gain. This information can help doctors and patients make better choices about treating depression in people who also have to watch out for diabetes.

Abstract: People with type 2 diabetes and albuminuria are at an elevated risk for cardiac and renal events. The optimal biomarkers to aid disease prediction and to understand the benefits of sodium-glucose cotransporter-2 inhibition remain unclear. Among 2627 study participants in the CREDENCE trial (Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation), concentrations of NT-proBNP (N-terminal pro-B-type natriuretic peptide), high-sensitivity cardiac troponin T, growth differentiation factor-15, and IGFBP7 (insulin-like growth factor binding protein 7) were measured. The effect of canagliflozin on biomarker concentrations was evaluated. The prognostic potential of each biomarker on the primary outcome (a composite of end-stage kidney disease [dialysis, transplantation, or a sustained estimated glomerular filtration rate of <15 mL·min·1.73 m], doubling of the serum creatinine level, or renal death or cardiovascular death) was assessed. The median (quartiles 1 and 3) concentration of each biomarker was generally elevated: NT-proBNP, 180 ng/L (82, 442 ng/L); high-sensitivity cardiac troponin T, 19 ng/L (12, 29 ng/L); growth differentiation factor-15, 2595 ng/L (1852, 3775 ng/L); and IGFBP7, 121.8 ng/mL (105.4, 141.5 ng/mL). At 1 year, the biomarkers all rose by 6% to 29% in the placebo arm but only by 3% to 10% in the canagliflozin arm (all <0.01 in multivariable linear mixed-effect models). Baseline concentrations of each biomarker were strongly predictive of cardiac and renal outcomes. When the biomarkers were analyzed together in a multimarker panel, individuals with high risk scores (hazard ratio [HR], 4.01 [95% CI, 2.52-6.35]) and moderate risk scores (HR, 2.39 [95% CI, 1.48-3.87]) showed a higher risk for the primary outcome compared with those with low risk scores. By 1 year, a 50% increase in NT-proBNP (HR, 1.11 [95% CI, 1.08-1.15]), high-sensitivity cardiac troponin T (HR, 1.86 [95% CI, 1.64-2.10]), growth differentiation factor-15 (HR, 1.45 [95% CI, 1.24-1.70]), and IGFBP7 (HR, 3.76 [95% CI, 2.54-5.56]) was associated with risk of the primary outcome. Multiple cardiorenal stress biomarkers are strongly prognostic in people with type 2 diabetes and albuminuria. Canagliflozin modestly reduced the longitudinal trajectory of rise in each biomarker. Change in the biomarker level in addition to the baseline level augments the primary outcome prediction. URL: https://www. gov; Unique identifier: NCT02065791.
Abstract Summary: Scientists did a study to help people with type 2 diabetes who also have a kidney problem that can cause heart issues. They wanted to find the best way to predict who might get sicker and see if a medicine called canagliflozin could help. They tested 2,627 people and looked at four different things in their blood that might show signs of heart and kidney stress.
They found that the levels of these things in the blood were higher than normal for most people in the study. After one year, the people who didn't get the medicine had their levels go up a lot, but the levels didn't go up as much in the people who took canagliflozin. The scientists also found that if these blood levels were high to start with, the person was more likely to have heart or kidney problems.
In conclusion, checking these four blood levels can help predict health problems in people with type 2 diabetes and kidney issues, and taking canagliflozin might slow down the increase of these levels. This is important because it could help doctors take better care of their patients.

Associations between low sex hormone concentrations and depression in older women: An observational study.
Maturitas.

Abstract: We investigated whether low sex hormone concentrations are associated with depression in older women. This was a cross-sectional study of Australian women, aged at least 70 years, not taking medications modulating sex hormone levels. Associations between hormones, measured by liquid chromatography-tandem mass spectrometry, and depression were examined by logistic regression adjusted for potential confounders. The primary outcome was a Center for Epidemiologic Studies Depression score >10, designated as 'depression', with an expanded definition that included anti-depressant use as a secondary outcome. For the 5535 participants in the analysis, median age 74.0 years (interquartile range 71.7-77.7), depression prevalence was 5.8 % (95 % CI 5.2-6.4 %). In the adjusted models, a statistically significantly greater likelihood of depression was seen for women with testosterone and oestrone blood concentrations in quartile 1 compared with quartiles 2-4 (odds ratio 1.33, 95 % CI 1.04 to 1.70, p = 0.022; and 1.37, 95 % CI 1.06 to 1.78, p = 0.017, respectively). For the expanded definition, the odds ratios for the lowest testosterone and oestrone quartile compared with other quartiles were 1.47 (95 % CI 1.24 to 1.75, p < 0.001) and 1.31 (95 % CI 1.09 to 1.58, p < 0.001), respectively. A significant association for low DHEA was seen only for the expanded definition of depression (1.36, 95 % CI 1.13 to 1.64, p = 0.001). Receiver operating characteristic curves showed that the contribution of each sex hormone to the likelihood of depression was small. Amongst older women not taking medications that influence sex hormone concentrations, low testosterone and oestrone levels are associated with a greater likelihood of depression, but the effects are small. International Standard Randomized Controlled Trial Number Register (ISRCTN83772183) and clinicaltrials.gov (NCT01038583).
Abstract Summary: Scientists wanted to find out if having low levels of certain hormones could make older women feel depressed. They looked at Australian women who were 70 years or older and not taking any hormone medicines. They tested the women's blood to measure their hormone levels and asked questions to see if they were feeling depressed.
They found that women with very low levels of two hormones, testosterone and oestrone, were a little more likely to feel depressed compared to women with higher levels. But, the difference was not very big. They also noticed that another hormone, DHEA, was only linked to feeling depressed when they included women taking antidepressants in their study.
The study shows that for older women not on hormone medicines, having lower levels of certain hormones might be connected to feeling depressed, but it doesn't make a big difference. This information could help doctors understand why some older women feel depressed.

Boosting NAD preferentially blunts Th17 inflammation via arginine biosynthesis and redox control in healthy and psoriasis subjects.
Cell Rep Med.
2023 Sep 19;
4(9):101157.
Abstract: To evaluate whether nicotinamide adenine dinucleotide-positive (NAD) boosting modulates adaptive immunity, primary CD4 T cells from healthy control and psoriasis subjects were exposed to vehicle or nicotinamide riboside (NR) supplementation. NR blunts interferon γ (IFNγ) and interleukin (IL)-17 secretion with greater effects on T helper (Th) 17 polarization. RNA sequencing (RNA-seq) analysis implicates NR blunting of sequestosome 1 (sqstm1/p62)-coupled oxidative stress. NR administration increases sqstm1 and reduces reactive oxygen species (ROS) levels. Furthermore, NR activates nuclear factor erythroid 2-related factor 2 (Nrf2), and genetic knockdown of nrf2 and the Nrf2-dependent gene, sqstm1, diminishes NR amelioratory effects. Metabolomics analysis identifies that NAD boosting increases arginine and fumarate biosynthesis, and genetic knockdown of argininosuccinate lyase ameliorates NR effects on IL-17 production. Hence NR via amino acid metabolites orchestrates Nrf2 activation, augments CD4 T cell antioxidant defenses, and attenuates Th17 responsiveness. Oral NR supplementation in healthy volunteers similarly increases serum arginine, sqstm1, and antioxidant enzyme gene expression and blunts Th17 immune responsiveness, supporting evaluation of NAD boosting in CD4 T cell-linked inflammation.
Abstract Summary: Scientists did an experiment to see if a special vitamin called nicotinamide riboside (NR) can help the body's immune system work better. They tested this on immune cells from healthy people and people with a skin condition called psoriasis. They found that NR made these cells less likely to create substances that can cause inflammation. The study also showed that NR helps protect cells from stress and boosts their defense systems. When they gave NR to healthy people, it had similar good effects. This research suggests that NR might be helpful for people with diseases that involve inflammation, like psoriasis.

Abstract: Ecological models suggest that interventions targeting specific behaviors are most effective when supported by the environment. This study prospectively examined the interactions between neighborhood walkability and an mHealth intervention in a large-scale, adequately powered trial to increase moderate-to-vigorous physical activity (MVPA). Healthy, insufficiently active adults (N = 512) were recruited purposefully from census block groups ranked on walkability (high/low) and socioeconomic status (SES, high/low). Participants were block-randomized in groups of four to WalkIT Arizona, a 12-month, 2 × 2 factorial trial evaluating adaptive versus static goal setting and immediate versus delayed financial reinforcement delivered via text messages. Participants wore ActiGraph GT9X accelerometers daily for one year. After recruitment, a walkability index was calculated uniquely for every participant using a 500-m street network buffer. Generalized linear mixed-effects hurdle models tested for interactions between walkability, intervention components, and phase (baseline vs. intervention) on: (1) likelihood of any (versus no) MVPA and (2) daily MVPA minutes, after adjusting for accelerometer wear time, neighborhood SES, and calendar month. Neighborhood walkability was probed at 5th, 25th, 50th, 75th, and 95th percentiles to explore the full range of effects. Adaptive goal setting was more effective in increasing the likelihood of any MVPA and daily MVPA minutes, especially in lower walkable neighborhoods, while the magnitude of intervention effect declined as walkability increased. Immediate reinforcement showed a greater increase in any and daily MVPA compared to delayed reinforcement, especially relatively greater in higher walkable neighborhoods. Results partially supported the synergy hypotheses between neighborhood walkability and PA interventions and suggest the potential of tailoring interventions to individuals' neighborhood characteristics. Preregistered at clinicaltrials.gov (NCT02717663).
Abstract Summary: Scientists did a study to see if a neighborhood that's easy to walk in and a phone app could help people exercise more. They looked at 512 adults who didn't move around much and lived in different kinds of neighborhoods. Some neighborhoods were easy to walk in, and some were not. They also looked at whether the neighborhoods were rich or not so rich. The study lasted a year, and people got text messages with goals for walking. Some got goals that changed, and some got the same goals. They also got rewards—some right away and some later.
The researchers found that changing goals helped people in less walkable places exercise more. Getting rewards right away helped too, especially in places that were already good for walking. This study shows that making exercise plans that fit where people live can help them be more active.

23(11):1266-1279.
Abstract: Malaria transmission-blocking vaccines target mosquito-stage parasites and will support elimination programmes. Gamete vaccine Pfs230D1-EPA/Alhydrogel induced superior activity to zygote vaccine Pfs25-EPA/Alhydrogel in malaria-naive US adults. Here, we compared these vaccines in malaria-experienced Malians. We did a pilot safety study then double-blind, block-randomised, comparator-controlled main-phase trial in malaria-intense Bancoumana, Mali. 18-50-year-old healthy non-pregnant, non-breastfeeding consenting adult residents were randomly assigned (1:1:1:1) to receive four doses at months 0, 1, 4·5, and 16·5 of either 47 μg Pfs25, 40 μg Pfs230D1 or comparator (Twinrix or Menactra)-all co-administered with normal saline for blinding-or 47 μg Pfs25 plus 40 μg Pfs230D1 co-administered. We documented safety and tolerability (primary endpoint in the as-treated populations) and immunogenicity (secondary endpoint in the as-treated populations: ELISA, standard-membrane-feeding assay, and mosquito direct skin feed assay). This trial is registered at ClinicalTrials.gov, NCT02334462. Between March 19, and June 2, 2015, we screened 471 individuals. Of 225 enrolled for the pilot and main cohorts, we randomly assigned 25 participants to pilot safety cohort groups of five (20%) to receive a two-dose series of Pfs25-EPA/Alhydrogel (16 μg), Pfs230D1-EPA/Alhydrogel (15 μg) or comparator, followed by Pfs25-EPA/Alhydrogel (16 μg) plus Pfs230D1-EPA/Alhydrogel (15 μg) or comparator plus saline. For the main cohort, we enrolled 200 participants between May 11 and June 2, 2015, to receive a four-dose series of 47 μg Pfs25-EPA/Alhydrogel plus saline (n=50 [25%]; Pfs25), 40 μg Pfs230D1-EPA/Alhydrogel plus saline (n=49 [25%]; Pfs230D1), 47 μg Pfs25-EPA/Alhydrogel plus 40 μg Pfs230D1-EPA/Alhydrogel (n=50 [25%]; Pfs25 plus Pfs230D1), or comparator (Twinrix or Menactra) plus saline (n=51 [25%]). Vaccinations were well tolerated in the pilot safety and main phases. Most vaccinees became seropositive after two Pfs230D1 or three Pfs25 doses; peak titres increased with each dose thereafter (Pfs230D1 geometric mean: 77·8 [95% CI 56·9-106·3], 146·4 [108·3-198·0], and 410·2 [301·6-558·0]; Pfs25 geometric mean 177·7 [130·3-242·4] and 315·7 [209·9-474·6]). Functional activity (mean peak transmission-reducing activity) appeared for Pfs230D1 (74·5% [66·6-82·5]) and Pfs25 plus Pfs230D1 (68·6% [57·3-79·8]), after the third dose and after the fourth dose (88·9% [81·7-96·2] for Pfs230D1 and 85·0% [78·4-91·5] Pfs25 plus Pfs230D1) but not for Pfs25 (58·2% [49·1-67·3] after the third dose and 58·2% [48·5-67·9] after the fourth dose). Pfs230D1 transmission-reducing activity (73·7% [64·1-83·3]) persisted 10 weeks after the fourth dose. Transmission-reducing activity of 80% was estimated at 1659 ELISA units for Pfs25, 218 for Pfs230D1, and 223 for Pfs230D1 plus Pfs25. After 3850 direct skin feed assays, 35 participants (12 Pfs25, eight Pfs230D1, five Pfs25 plus Pfs230D1, and ten comparator) had transmitted parasites at least once. The proportion of positive assays in vaccine groups (Pfs25 33 [3%] of 982 [-0·013 to 0·014], Pfs230D1 22 [2%] of 954 [-0·005 to 0·027], and combination 11 [1%] of 940 [-0·024 to 0·002]) did not differ from that of the comparator (22 [2%] of 974), nor did Pfs230D1 and combination groups differ (-0·024 to 0·001). Pfs230D1 but not Pfs25 vaccine induces durable serum functional activity in Malian adults. Direct skin feed assays detect parasite transmission to mosquitoes but increased event rates are needed to assess vaccine effectiveness. Intramural Research Program of the National Institute of Allergy and Infectious Diseases and US National Institutes of Health.
Abstract Summary: Scientists did a study to see if new malaria vaccines could help stop the spread of malaria in Mali, where people often get the disease. They tested two vaccines, Pfs230D1 and Pfs25, on adults who had experienced malaria before. The vaccines were given in four doses over about 16 months. They wanted to see if the vaccines were safe, if people's bodies accepted them, and if they could stop mosquitoes from getting malaria when they bite people.
They found that both vaccines were safe and that people's bodies responded well to them. The Pfs230D1 vaccine worked better than the Pfs25 vaccine. It helped stop mosquitoes from getting malaria for a longer time. They also tried giving both vaccines together, and this worked well too.
The study showed that the Pfs230D1 vaccine could be a good way to help stop the spread of malaria. This is important because it means there might be a new tool to fight malaria, which can make a lot of people very sick or even cause death.

Increasing Physical Activity in Persons With Spinal Cord Injury With an eHealth-Based Adaptive Exercise Intervention: Protocol for a Sequential Multiple Assignment Randomized Trial.
JMIR Res Protoc.
2023 Jul 27;
12:e47665.
Abstract: Participating in an adequate amount of physical activity to acquire health benefits is challenging for people with spinal cord injury (SCI) due to personal and logistic barriers. Barriers in the built and social environments may include lack of transportation, lack of accessible facilities or programs, and lack of training among fitness personnel. Low self-efficacy, lack of self-regulation skills, and improper outcome expectations are examples of personal barriers. Current approaches to investigating physical activity programs in people with SCI have been limited to traditional "one-size-fits-all" design, which has yielded low adherence rates, high dropout rates, and participants not maintaining physical activity levels at follow-up. The primary aim of this study is to test the feasibility of a tele-exercise program that applies an adaptive intervention design for 30 adults with SCI, targeting increases in adherence to the exercise program and physical activity participation. The Sequential Multiple Assignment Randomized Trial for Home-based Exercise and Lifestyle Tele-Health (SMART-HEALTH) is a 12-week, home-based, movement-to-music (M2M) program. The goal of a SMART-designed study is to develop an adaptive intervention that modifies support provisions based on response levels. In SMART-HEALTH, 2 groups of participants will undergo 3-week and 6-week asynchronous M2M interventions in the first phase. Participants who did not achieve the desired adherence rate (≥95% of video watch minutes) will be rerandomized into M2M Live (switch) or individualized behavioral coaching (augmented with the asynchronous M2M program). The study will primarily assess rates of recruitment or enrollment, adherence and retention, timing to identify nonresponders, and scientific outcomes (eg, physical activity and exercise self-efficacy). The study will qualitatively evaluate the acceptability of the study using semistructured interviews among participants who complete the 12-week intervention. Recruitment procedures started in June 2022. All data are expected to be collected by September 2023. Full trial results are expected to be published by March 2024. Secondary analyses of data will be subsequently published. Results will include exercise adherence rates; changes in self-reported physical activity levels and blood pressure; and changes in secondary conditions including pain, sleep, and fatigue. Thematic analysis of semistructured interviews will include results on participant enjoyment and acceptability of SMART-HEALTH and inform modifications for future delivery of the program. This study will strengthen our understanding of the potential benefits of the tele-exercise intervention for people with SCI and build upon adaptive intervention design and its delivery strategies that aim to increase adoption and sustainable exercise behavior. This pilot trial will inform future SMART-designed studies and provide new and innovative strategies for investigating intervention effects on physical activity behavior in the SCI population. ClinicalTrials.gov NCT04726891; https://classic.clinicaltrials.gov/ct2/show/NCT04726891. DERR1-10.2196/47665.
Abstract Summary: Scientists are trying to help adults with spinal cord injuries (SCI) exercise more because it's often hard for them to stay active. They face problems like not being able to get to places where they can exercise, not finding places that are easy for them to use, and sometimes they don't believe they can do it. The study is testing a new way to exercise at home using videos and the internet. It's called the SMART-HEALTH program and it involves moving to music. They want to see if people like this program and will stick with it.
They're checking if people start the program, keep doing it, and how well it works. Some people will get extra help or different kinds of support if they're not sticking to the program. They started looking for people to join the study in June 2022 and will finish collecting information by September 2023. They'll share what they learn by March 2024.
They hope this study will show that exercising at home with videos is good for people with SCI and that it can help them keep exercising on their own. This could lead to better ways to help people with SCI stay active and healthy.

Disuse-induced muscle fibrosis, cellular senescence, and senescence-associated secretory phenotype in older adults are alleviated during re-ambulation with metformin pre-treatment.
Aging Cell.
2023 Nov;
22(11):e13936.
Abstract: Muscle inflammation and fibrosis underlie disuse-related complications and may contribute to impaired muscle recovery in aging. Cellular senescence is an emerging link between inflammation, extracellular matrix (ECM) remodeling and poor muscle recovery after disuse. In rodents, metformin has been shown to prevent cellular senescence/senescent associated secretory phenotype (SASP), inflammation, and fibrosis making it a potentially practical therapeutic solution. Thus, the purpose of this study was to determine in older adults if metformin monotherapy during bed rest could reduce muscle fibrosis and cellular senescence/SASP during the re-ambulation period. A two-arm controlled trial was utilized in healthy male and female older adults (n = 20; BMI: <30, age: 60 years+) randomized into either placebo or metformin treatment during a two-week run-in and 5 days of bedrest followed by metformin withdrawal during 7 days of recovery. We found that metformin-treated individuals had less type-I myofiber atrophy during disuse, reduced pro-inflammatory transcriptional profiles, and lower muscle collagen deposition during recovery. Collagen content and myofiber size corresponded to reduced whole muscle cellular senescence and SASP markers. Moreover, metformin treatment reduced primary muscle resident fibro-adipogenic progenitors (FAPs) senescent markers and promoted a shift in fibroblast fate to be less myofibroblast-like. Together, these results suggest that metformin pre-treatment improved ECM remodeling after disuse in older adults by possibly altering cellular senescence and SASP in skeletal muscle and in FAPs.
Abstract Summary: Scientists did a study to see if a medicine called metformin could help older people's muscles recover better after they had to stay in bed and not move much. When people don't move, their muscles can get weak and sore, and this can be worse for older people. The study had 20 older men and women take either metformin or a fake pill before and during 5 days of bed rest. Then they stopped taking the pills and started moving again for 7 days. The researchers found that the people who took metformin didn't lose as much muscle strength and didn't get as much muscle soreness as those who took the fake pill. This means metformin might help older people's muscles stay strong and healthy when they can't move around for a little while.

Sodium Oxybate in Alcohol-Responsive Essential Tremor of Voice: An Open-Label Phase II Study.
Mov Disord.

38(10):1936-1944.
Abstract: Essential tremor of voice (ETv) is characterized by involuntary oscillations of laryngeal and upper airway muscles, causing rhythmic alterations in pitch and loudness during both passive breathing and active laryngeal tasks, such as speaking and singing. Treatment of ETv is challenging and typically less effective compared with treatment of ET affecting extremities. We conducted a proof-of-concept, open-label phase II study to examine the efficacy and central effects of sodium oxybate in patients with alcohol-responsive ETv. All subjects received 1.0 to 1.5 g of oral sodium oxybate and underwent brain functional magnetic resonance imaging. The primary endpoint was the number of patients (% from total) with reduced ETv symptoms by at least 10% at about 40 to 45 minutes after sodium oxybate intake based on the combined visual analog scale score of ETv symptom severity. The secondary endpoint included changes in brain activity after sodium oxybate intake compared to baseline. Sodium oxybate reduced ETv symptoms on average by 40.8% in 92.9% of patients. Drug effects were observed about 40 to 45 minutes after intake, lasting about 3.5 hours, and gradually wearing off by the end of the fifth hour. The central effects of sodium oxybate were associated with normalized activity in the cerebellum, inferior/superior parietal lobules, inferior frontal gyrus, and insula and re-established functional relationships between these regions. Sodium oxybate showed high efficacy in ETv patients, with a likely central action on disorder pathophysiology. Sodium oxybate may be an effective novel oral drug for treatment of alcohol-responsive ETv patients. © 2023 The Authors.

Abstract Summary: Scientists did a study to see if a medicine called sodium oxybate could help people with a shaky voice, a condition where muscles in the throat move without control. This shaking can make the voice sound wobbly or change volume unexpectedly. It's hard to treat, especially when compared to shaking in the arms or legs. In the study, people with shaky voice took the medicine and then had a special brain scan called an MRI. The researchers wanted to see if the medicine made the shaking less and what it did to the brain.
They found that after taking the medicine, most of the people's voices got a lot better—about 40% better! This improvement happened about 40 minutes after taking the medicine and lasted for around 3.5 hours. The brain scans showed that the medicine made certain parts of the brain work more normally and helped these parts communicate better with each other.
This is good news because it means sodium oxybate might be a new medicine that can help people who have a shaky voice, especially if their condition gets better when they drink alcohol.

Abstract: The insulin-like growth factors (IGF) play a crucial role in regulating cellular proliferation, apoptosis, and key metabolic pathways. The ratio of IGF-1 to IGF binding protein-3 (IGFBP-3) is an important factor in determining IGF-1 bioactivity. We sought to investigate the association of IGF-1 and IGFBP-3 with cardio-renal outcomes among persons with type 2 diabetes. Samples were available from 2627 individuals with type 2 diabetes and chronic kidney disease that were randomized to receive canagliflozin or placebo and were followed up for incident cardio-renal events. Primary outcome was defined as a composite of end-stage kidney disease, doubling of the serum creatinine level, or renal/cardiovascular death. IGF-1 and IGFBP-3 were measured at baseline, Year-1 and Year-3. Elevated IGF-1 level was defined according to age-specific cutoffs. Cox proportional hazard regression was used to investigate the association between IGF-1 level, IGFBP-3, and the ratio of IGF-1/IGFBP-3 with clinical outcomes. Elevated IGF-1 was associated with lower glomerular filtration rate at baseline. Treatment with canagliflozin did not significantly change IGF-1 and IGFBP-3 concentrations by 3 years (p-value > 0.05). In multivariable models, elevated IGF-1 (above vs below age-specific cutoffs) was associated with the primary composite outcome (incidence rate:17.8% vs. 12.7% with a hazard ratio [HR]: 1.52; 95% confidence interval CI 1.09-2.13;P: 0.01), renal composite outcome (HR: 1.65; 95% CI 1.14-2.41; P: 0.01), and all-cause mortality (HR: 1.52; 95% CI 1.00-2.32; P; 0.05). Elevations in log IGFBP-3 did not associate with any clinical outcomes. Increase in log IGF-1/IGFBP-3 ratio was also associated with a higher risk of the primary composite outcome (HR per unit increase: 1.57; 95% CI 1.09-2.26; P; 0.01). These results further suggest potential importance of IGF biology in the risk for cardio-renal outcomes in type 2 diabetes. SGLT2 inhibition has no impact on the biology of IGF despite its significant influence on outcomes. CREDENCE; ClinicalTrials.gov Identifier: NCT02065791.
Abstract Summary: Scientists did a study to see how certain growth factors in the body, which help cells grow and stay healthy, are linked to heart and kidney problems in people with type 2 diabetes. They looked at 2627 people with diabetes and kidney disease who were either given a diabetes medicine called canagliflozin or a placebo. They checked the levels of these growth factors when the study started, after one year, and after three years.
They found that people with higher levels of a growth factor called IGF-1 often had worse kidney function at the start. Also, those with higher IGF-1 levels were more likely to have serious kidney and heart problems or to die from these issues. The medicine didn't really change the levels of these growth factors.
This study is important because it shows that the amount of IGF-1 in the body could help doctors figure out who might have a higher risk of heart and kidney problems if they have type 2 diabetes. This could help in taking care of their health better.

Abstract: Late-life depression is associated with substantial heterogeneity in clinical presentation, disability, and response to antidepressant treatment. We examined whether self-report of severity of common symptoms, including anhedonia, apathy, rumination, worry, insomnia, and fatigue were associated with differences in presentation and response to treatment. We also examined whether these symptoms improved during treatment with escitalopram. Eighty-nine older adults completed baseline assessments, neuropsychological testing and providing self-reported symptom and disability scales. They then entered an 8-week, placebo-controlled randomized trial of escitalopram, and self-report scales were repeated at the trial's end. Raw symptom scale scores were combined into three standardized symptom phenotypes and models examined how symptom phenotype severity was associated with baseline measures and depression improvement over the trial. While rumination/worry appeared independent, severity of apathy/anhedonia and fatigue/insomnia were associated with one another and with greater self-reported disability. Greater fatigue/insomnia was also associated with slower processing speed, while rumination/worry was associated with poorer episodic memory. No symptom phenotype severity score predicted a poorer overall response to escitalopram. In secondary analyses, escitalopram did not improve most phenotypic symptoms more than placebo, aside for greater reductions in worry and total rumination severity. Deeper symptom phenotype characterization may highlight differences in the clinical presentation of late-life depression. However, when compared to placebo, escitalopram did not improve many of the symptoms assessed. Further work is needed to determine whether symptom phenotypes inform longer-term course of illness, and which treatments may best benefit specific symptoms.
Abstract Summary: Scientists wanted to learn more about how older people with depression feel different symptoms and how they respond to a depression medicine called escitalopram. They asked 89 older adults to tell them about their feelings, like if they were sad, didn't care about things, worried a lot, couldn't sleep, or were really tired. These adults also took some thinking tests and told the scientists how their symptoms affected their daily lives. Then, the adults took either the real medicine or a pretend pill for 8 weeks, and they shared how they felt again at the end.
The scientists found that feeling really tired or not being able to sleep was linked to having a harder time with daily activities and thinking quickly. Worrying a lot was linked to having trouble remembering things. But how severe these feelings were didn't change how well the medicine worked. The medicine did help with worrying and thinking the same sad thoughts over and over, but it didn't help much with the other feelings compared to the pretend pill.
This study shows that it's important to understand the different ways depression can affect older adults. Even though the medicine didn't help with all the symptoms, knowing more about these feelings can help doctors find better ways to help people with depression.

Abstract: Tobacco use continues to be a leading preventable cause of death and disease in the United States, accounting for >480,000 deaths each year. Although treatments for tobacco use are effective for many, there is substantial variability in outcomes, and these approaches are not effective for all individuals seeking to quit smoking cigarettes. New, effective therapeutic approaches are needed to meet the preferences of people who want to stop smoking. Guided imagery (GI) is a mind-body technique that involves the guided visualization of specific mental images, which is enhanced with other sensory modalities and emotions. Preliminary evidence provides initial support for the use of GI as a treatment for cigarette smoking. Meta-analyses have shown that standard treatment for cigarette smoking delivered over the telephone via quitlines is effective. A telephone-based intervention that uses GI might provide another effective treatment option and increase the reach and effectiveness of quitlines. This study aims to test the efficacy of Be Smoke Free, a telephone-delivered GI treatment for smoking cessation. This multisite randomized clinical trial (RCT) will compare a novel telephone-delivered GI tobacco cessation treatment with a standard evidence-based behavioral treatment. The study will be conducted over 5 years. In phase 1, we refined protocols and procedures for the New York State and West Virginia sites for use in the RCT. During phase 2, we will conduct an RCT with 1200 participants: 600 (50%) recruited via quitlines and 600 (50%) recruited via population-based methods. Participants will be randomly assigned to either the GI condition or the behavioral condition; both treatments will be delivered by trained study coaches located at the University of Arizona. Assessments will be conducted at baseline and 3 and 6 months after enrollment by University of Arizona research staff. The primary outcome will be self-reported 30-day point prevalence abstinence 6 months after enrollment. Secondary outcomes include biochemically verified 7-day point prevalence abstinence 6 months after enrollment. Recruitment in West Virginia and New York began in October 2022. As of March 31, 2023, a total of 242 participants had been enrolled. Follow-up assessments began in November 2022. As of March 31, 2023, of the 118 eligible participants, 97 (82.2%) had completed the 3-month assessment, and 93% (26/28) of eligible participants had completed the 6-month assessment. Biochemical verification and qualitative interviews began in April 2023. Recruitment will continue through 2025 and follow-up assessments through 2026. Primary results are expected to be published in 2027. The Be Smoke Free study is a first-of-its-kind RCT that incorporates GI into telephone-based tobacco cessation treatment. If successful, Be Smoke Free will have substantial benefits for the long-term health of people who use tobacco across the United States. ClinicalTrials.gov NCT05277831; https://clinicaltrials.gov/ct2/show/NCT05277831. PRR1-10.2196/48898.
Abstract Summary: Scientists are doing a big study to see if a special way of using your imagination can help people stop smoking. Smoking is a big problem because it makes a lot of people sick and can even cause death. The study is called "Be Smoke Free," and it's trying to find out if guiding people to picture things in their minds can be a good way to help them quit smoking. They are comparing this new idea with the usual ways that help people stop smoking. They talk to people on the phone and give them advice. They will talk to 1200 people in total, with half of them getting the new imagination treatment and the other half getting the usual advice. They want to see which one works better. They started the study in October 2022 and will keep going until 2025. They will check on the people who joined the study after 3 and 6 months to see if they have stopped smoking. If this new way works, it could help a lot of people be healthier and not smoke anymore.

Abstract: Research participants often misunderstand the required elements of informed consent information, whether provided in written or oral format. Informed consent instruments with embedded evidence-based learning theory principles administered in multimedia electronic formats may improve comprehension and retention. This study aims to determine whether study information comprehension and retention using an interactive multimedia video consent process was noninferior to comprehension and retention after an in-person face-to-face interaction with a conventional written consent document for caregivers and adolescents enrolled in a clinical trial. Participants were caregivers and children aged 12 to 17 years who were enrolled in a clinical trial of asthma treatment. Consent information was presented as a multimedia web-based video consent interaction or as a conventional written consent document with in-person interaction between the prospective participants and the study staff. The trial used a parallel nonrandomized noninferiority design that compared the 2 consent methods. Caregivers and adolescents completed a 17-item open-ended comprehension questionnaire (score range 17-51) at enrollment and at the end of the study 20 weeks later. Comprehension and retention were compared between the consent formats. Noninferiority was established if the 95% CI upper bound of the difference in scores (conventional format minus web-based) was less than the noninferiority margin of 2.4; superiority was established if the upper bound of the CI was <0. In total, 54 caregiver and adolescent dyads completed the interactive multimedia web-based video consent, and 25 dyads completed the conventional consent. Overall, 33% (26/79) of all adolescents were Black, 57% (45/79) were male, and 61% (48/79) had a household income of <US $60,000 per year. For caregivers, the interactive multimedia web-based format was noninferior to the conventional format at enrollment (difference between the conventional and web-based formats: mean -0.30, 95% CI -2.52 to 1.92) and was superior at the end of the study 20 weeks later (mean -2.20, 95% CI -3.9 to -0.5). There was a loss of comprehension over 20 weeks (mean -1.65, 95% CI -3.1 to -0.19) with the conventional format but not with the multimedia web-based format (mean 0.14, 95% CI -0.84 to 1.12). For adolescents, the noninferiority of the multimedia web-based format was not established. Caregivers who are considering enrolling their adolescent in an asthma clinical trial have similar comprehension of study information when delivered through an interactive multimedia web-based platform, which incorporates evidence-based learning theory principles, compared with having a conventional in-person, face-to-face discussion. The retention of study information over time was better with the multimedia format for caregivers. ClinicalTrials.gov NCT02061280; https://clinicaltrials.gov/ct2/show/NCT02061280 and NCT01437995; https://clinicaltrials.gov/ct2/show/NCT01437995.
Abstract Summary: Scientists wanted to see if a video that explains a study to kids and their parents is just as good as talking to someone in person and reading about the study. They tested this with families who were learning about an asthma study. Some families watched an interactive video, while others read a paper and talked to the study team. They asked the families questions to see how well they understood the study right after they learned about it and again 20 weeks later.
They found that parents who watched the video understood the study just as well as those who talked to someone in person. Even better, the parents remembered the information longer if they watched the video. But for the kids, the video wasn't proven to be as good as talking to someone in person. This means that using videos could be a good way to help parents understand and remember information when they're thinking about joining a study with their kids.

Abstract: Background Sodium glucose cotransporter-2 inhibitors reduce systolic blood pressure (SBP), but whether they affect SBP variability is unknown. There also remains uncertainty regarding the prognostic value of SBP variability for different clinical outcomes. Methods and Results Using individual participant data from the CANVAS (Canagliflozin Cardiovascular Assessment Study) Program and CREDENCE (Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation) trial, we assessed the effect of canagliflozin on SBP variability in people with type 2 diabetes across 4 study visits over 1.5 years as measured by standard deviation, coefficient of variation, and variability independent of the mean. We used multivariable Cox regression models to estimate associations of SBP variability with cardiovascular, kidney, and mortality outcomes. In 11 551 trial participants, canagliflozin modestly lowered the standard deviation of SBP variability (-0.25 mm Hg [95% CI, -0.44 to -0.06]), but there was no effect on coefficient of variation (0.02% [95% CI, -0.12 to 0.16]) or variability independent of the mean (0.08 U [95% CI, -0.11 to 0.26]) when adjusting for correlation with mean SBP. Each 1 standard deviation increase in standard deviation of SBP variability was independently associated with higher risk of hospitalization for heart failure (hazard ratio [HR], 1.19 [95% CI, 1.02-1.38]) and all-cause mortality (HR, 1.12 [95% CI, 1.01-1.25]), with consistent results observed for coefficient of variation and variability independent of the mean. Increases in SBP variability were not associated with kidney outcomes. Conclusions In people with type 2 diabetes at high cardiovascular risk or with chronic kidney disease, higher visit-to-visit SBP variability is independently associated with risks of hospitalization for heart failure and all-cause mortality. Canagliflozin has little to no effect on SBP variability, independent of its established SBP-lowering effect.

Abstract Summary: Doctors wanted to see if a diabetes medicine called canagliflozin could make blood pressure less up-and-down in people with type 2 diabetes. They checked the blood pressure of over 11,000 people many times for 1.5 years. They found that the medicine made blood pressure a tiny bit steadier, but not by much. They also learned that when blood pressure goes up and down a lot, it can lead to more hospital visits for heart problems and a higher chance of dying from any cause. However, these ups and downs didn't seem to affect kidney health. This study helps us understand that keeping blood pressure steady is important for staying healthy, but this medicine doesn't help much with that.

Effect of Low-Dose Aspirin Versus Placebo on Incidence of Anemia in the Elderly : A Secondary Analysis of the Aspirin in Reducing Events in the Elderly Trial.
Ann Intern Med.
2023 Jul;
176(7):913-921.
Abstract: Daily low-dose aspirin increases major bleeding; however, few studies have investigated its effect on iron deficiency and anemia. To investigate the effect of low-dose aspirin on incident anemia, hemoglobin, and serum ferritin concentrations. Post hoc analysis of the ASPREE (ASPirin in Reducing Events in the Elderly) randomized controlled trial. (ClinicalTrials.gov: NCT01038583). Primary/community care in Australia and the United States. Community-dwelling persons aged 70 years or older (≥65 years for Black persons and Hispanic persons). 100 mg of aspirin daily or placebo. Hemoglobin concentration was measured annually in all participants. Ferritin was measured at baseline and 3 years after random assignment in a large subset. 19 114 persons were randomly assigned. Anemia incidence in the aspirin and placebo groups was 51.2 events and 42.9 events per 1000 person-years, respectively (hazard ratio, 1.20 [95% CI, 1.12 to 1.29]). Hemoglobin concentrations declined by 3.6 g/L per 5 years in the placebo group and the aspirin group experienced a steeper decline by 0.6 g/L per 5 years (CI, 0.3 to 1.0 g/L). In 7139 participants with ferritin measures at baseline and year 3, the aspirin group had greater prevalence than placebo of ferritin levels less than 45 µg/L at year 3 (465 [13%] vs. 350 [9.8%]) and greater overall decline in ferritin by 11.5% (CI, 9.3% to 13.7%) compared with placebo. A sensitivity analysis quantifying the effect of aspirin in the absence of major bleeding produced similar results. Hemoglobin was measured annually. No data were available on causes of anemia. Low-dose aspirin increased incident anemia and decline in ferritin in otherwise healthy older adults, independent of major bleeding. Periodic monitoring of hemoglobin should be considered in older persons on aspirin. National Institutes of Health and Australian National Health and Medical Research Council.
Abstract Summary: Scientists did a study to see if taking a small amount of aspirin every day affects people's blood levels and iron. They looked at older people, some who took aspirin and some who took a pretend pill (placebo). They found that the group taking aspirin had more cases of anemia, which means not having enough healthy red blood cells, and they also had lower iron levels. This happened even when they didn't have any big bleeding problems. The study suggests that older people who take aspirin should have their blood checked regularly to make sure they're not getting anemia.

Abstract: Polygenic risk scores (PRS) have potential to improve health care by identifying individuals that have elevated risk for common complex conditions. Use of PRS in clinical practice, however, requires careful assessment of the needs and capabilities of patients, providers, and health care systems. The electronic Medical Records and Genomics (eMERGE) network is conducting a collaborative study which will return PRS to 25,000 pediatric and adult participants. All participants will receive a risk report, potentially classifying them as high risk (∼2-10% per condition) for 1 or more of 10 conditions based on PRS. The study population is enriched by participants from racial and ethnic minority populations, underserved populations, and populations who experience poorer medical outcomes. All 10 eMERGE clinical sites conducted focus groups, interviews, and/or surveys to understand educational needs among key stakeholders-participants, providers, and/or study staff. Together, these studies highlighted the need for tools that address the perceived benefit/value of PRS, types of education/support needed, accessibility, and PRS-related knowledge and understanding. Based on findings from these preliminary studies, the network harmonized training initiatives and formal/informal educational resources. This paper summarizes eMERGE's collective approach to assessing educational needs and developing educational approaches for primary stakeholders. It discusses challenges encountered and solutions provided.
Abstract Summary: Scientists are doing a big study to see if special scores called "Polygenic risk scores" (PRS) can help doctors figure out who might get certain health problems. They're going to tell 25,000 kids and grown-ups if they have a high chance of getting any of 10 different health issues. They're making sure to include people from different backgrounds and those who usually don't get as much medical help.
The team talked to lots of people – those who might get their PRS, doctors, and the study team – to learn what they need to know about these scores. They found out that people need more tools and teaching to really understand and use these scores well.
The study is making special training and learning stuff to help everyone involved. They're sharing what they learned about teaching people about PRS and how to make it easier for everyone to use. This could help make health care better for lots of people by catching health problems early.

Abstract: Individuals with autism spectrum disorder (ASD) have significant impairment in social competence and reduced social salience. SENSE Theatre, a peer-mediated, theater-based intervention has demonstrated posttreatment gains in face memory and social communication. The multisite randomized clinical trial compared the Experimental (EXP; SENSE Theatre) to an Active Control Condition (ACC; Tackling Teenage Training, TTT) at pretest, posttest, and follow-up. It was hypothesized that the EXP group would demonstrate greater incidental face memory (IFM) and better social behavior (interaction with novel peers) and social functioning (social engagement in daily life) than the ACC group, and posttest IFM would mediate the treatment effect on follow-up social behavior and functioning. Two hundred ninety participants were randomized to EXP ( = 144) or ACC ( = 146). Per protocol sample (≥ 7/10 sessions) resulted in 207 autistic children 10-16 years. Event-related potentials measured IFM. Naive examiners measured social behavior (Vocal Expressiveness, Quality of Rapport, Social Anxiety) and functioning (Social Communication). Structural equation modeling was used to assess treatment effects. SENSE Theatre participants showed significantly better IFM ( = .874, = .039) at posttest, and significant indirect effects on follow-up Vocal Expressiveness × = .064, with 90% CI [.014, .118] and Quality of Rapport × = .032, with 90% CI [.002, .087] through posttest IFM. SENSE Theatre increases social salience as reflected by IFM, which in turn affected Vocal Expressiveness and Quality of Rapport. Results indicate that a neural mechanism supporting social cognition and driven by social salience is engaged by the treatment and has a generalized, indirect effect on clinically meaningful functional outcomes related to core symptoms of autism. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
Abstract Summary: Scientists did a study to see if a special theater program called SENSE Theatre could help kids with autism get better at remembering faces and interacting with others. They compared it to another program called Tackling Teenage Training. They thought the kids in the theater program would do better at remembering faces they saw by accident and would be better at talking to new people and joining in everyday social activities.
They had 290 kids with autism, ages 10 to 16, join the study and split them into two groups. One group did the theater program and the other did the other program. They checked how well the kids remembered faces and how they acted with people they didn't know before, during, and after the programs.
The kids who did the theater program got better at remembering faces and were more expressive and comfortable when talking to new people later on. The study showed that the theater program helped the kids' brains focus more on social stuff, which made them better at social skills that are usually hard for people with autism. This means that doing fun activities like theater might really help kids with autism in their daily lives.

Aneuploidy effects on human gene expression across three cell types.
Proc Natl Acad Sci U S A.

Abstract: Aneuploidy syndromes impact multiple organ systems but understanding of tissue-specific aneuploidy effects remains limited-especially for the comparison between peripheral tissues and relatively inaccessible tissues like brain. Here, we address this gap in knowledge by studying the transcriptomic effects of chromosome X, Y, and 21 aneuploidies in lymphoblastoid cell lines, fibroblasts and iPSC-derived neuronal cells (LCLs, FCL, and iNs, respectively). We root our analyses in sex chromosome aneuploidies, which offer a uniquely wide karyotype range for dosage effect analysis. We first harness a large LCL RNA-seq dataset from 197 individuals with one of 6 sex chromosome dosages (SCDs: XX, XXX, XY, XXY, XYY, and XXYY) to i) validate theoretical models of SCD sensitivity and ii) define an expanded set of 41 genes that show obligate dosage sensitivity to SCD and are all in (i.e., reside on the X or Y chromosome). We then use multiple complementary analyses to show that effects of SCD in LCLs are preserved in both FCLs (n = 32) and iNs (n = 24), whereas effects (i.e., those on autosomal gene expression) are mostly not preserved. Analysis of additional datasets confirms that the greater cross-cell type reproducibility of vs. effects is also seen in trisomy 21 cell lines. These findings i) expand our understanding of X, Y, and 21 chromosome dosage effects on human gene expression and ii) suggest that LCLs may provide a good model system for understanding effects of aneuploidy in harder-to-access cell types.
Abstract Summary: Scientists did a study to learn more about how having an extra or missing chromosome affects different parts of the body, like the brain and blood cells. They looked at genes in three types of cells: blood cells, skin cells, and brain cells made from stem cells. They focused on changes in the X and Y chromosomes (which determine if someone is male or female) and chromosome 21 (an extra copy of which causes Down syndrome).
They found 41 genes that are really sensitive to the number of sex chromosomes a person has. These genes are on the X or Y chromosome. The changes they saw in the blood cells were also seen in the skin and brain cells. But changes in other chromosomes were different in each type of cell.
Their research helps us understand how different cells in the body are affected by having an extra or missing chromosome. It also shows that studying blood cells can give us good clues about what might be happening in other parts of the body that are harder to study, like the brain.

Abstract: Heart failure (HF) is the leading cause of hospitalization among older adults in the United States. There are substantial racial and geographic disparities in HF outcomes, with patients living in southern US states having a mortality rate 69% higher than the national average. Self-management behaviors, particularly daily weight monitoring and physical activity, are extremely important in improving HF outcomes; however, patients typically have particularly low adherence to these behaviors. With the rise of digital technologies to improve health outcomes and motivate health behaviors, sensor-controlled digital games (SCDGs) have become a promising approach. SCDGs, which leverage sensor-connected technologies, offer the benefits of being portable and scalable and allowing for continuous observation and motivation of health behaviors in their real-world contexts. They are also becoming increasingly popular among older adults and offer an immersive and accessible way to measure self-management behaviors and improve adherence. No SCDGs have been designed for older adults or evaluated to test their outcomes. This randomized clinical trial aims to assess the efficacy of a SCDG in integrating the behavioral data of participants with HF from weight scale and activity tracker sensors to activate game progress, rewards, and feedback and, ultimately, to improve adherence to important self-management behaviors. A total of 200 participants with HF, aged ≥45 years, will be recruited and randomized into 2 groups: the SCDG playing group (intervention group) and sensor-only group (control group). Both groups will receive a weight scale, physical activity tracker, and accompanying app, whereas only the intervention group will play the SCDG. This design, thereby, assesses the contributions of the game. All participants will complete a baseline survey as well as posttests at 6 and 12 weeks to assess the immediate effect of the intervention. They will also complete a third posttest at 24 weeks to assess the maintenance of behavioral changes. Efficacy and benefits will be assessed by measuring improvements in HF-related proximal outcomes (self-management behaviors of daily weight monitoring and physical activity) and distal outcomes (HF hospitalization, quality of life, and functional status) between baseline and weeks 6, 12, and 24. The primary outcome measured will be days with weight monitoring, for which this design provides at least 80% power to detect differences between the 2 groups. Recruitment began in the fall of 2022, and the first patient was enrolled in the study on November 7, 2022. Recruitment of the last participant is expected in quarter 1 of 2025. Publication of complete results and data from this study is expected in 2026. This project will generate insight and guidance for scalable and easy-to-use digital gaming solutions to motivate persistent adherence to HF self-management behaviors and improve health outcomes among individuals with HF.

Abstract Summary: Doctors are trying to help older people who have heart problems stay out of the hospital. They noticed that in the South, more people with heart problems pass away compared to other places. One way to stay healthy is to check your weight every day and move around a lot, but many people forget to do these things. Now, doctors are testing a special video game that works with tools like a weight scale and a step counter to see if it can help people remember to do these healthy activities. They are going to have 200 people over 45 years old play this game. Some will just use the tools without the game, and some will use both. They want to see if the game helps people stay healthier and out of the hospital. They started the test in November 2022 and will finish in 2025. They will share what they learn in 2026. This could help make a fun game that encourages people to take better care of their hearts.

High tissue-sodium associates with systemic inflammation and insulin resistance in obese individuals.
Nutr Metab Cardiovasc Dis.
2023 Jul;
33(7):1398-1406.
Abstract: High sodium intake is associated with obesity and insulin resistance, and high extracellular sodium content may induce systemic inflammation, leading to cardiovascular disease. In this study, we aim to investigate whether high tissue sodium accumulation relates with obesity-related insulin resistance and whether the pro-inflammatory effects of excess tissue sodium accumulation may contribute to such association. In a cross-sectional study of 30 obese and 53 non-obese subjects, we measured insulin sensitivity determined as glucose disposal rate (GDR) using hyperinsulinemic euglycemic clamp, and tissue sodium content using Na magnetic resonance imaging. Median age was 48 years, 68% were female and 41% were African American. Median (interquartile range) BMI was 33 (31.5, 36.3) and 25 (23.5, 27.2) kg/m in the obese and non-obese individuals, respectively. In obese individuals, insulin sensitivity negatively correlated with muscle (r = -0.45, p = 0.01) and skin sodium (r = -0.46, p = 0.01). In interaction analysis among obese individuals, tissue sodium had a greater effect on insulin sensitivity at higher levels of high-sensitivity C-reactive protein (p-interaction = 0.03 and 0.01 for muscle and skin Na+, respectively) and interleukin-6 (p-interaction = 0.024 and 0.003 for muscle and skin Na+, respectively). In interaction analysis of the entire cohort, the association between muscle sodium and insulin sensitivity was stronger with increasing levels of serum leptin (p-interaction = 0.01). Higher muscle and skin sodium are associated with insulin resistance in obese patients. Whether high tissue sodium accumulation has a mechanistic role in the development of obesity-related insulin resistance through systemic inflammation and leptin dysregulation remains to be examined in future studies. gov registration: NCT02236520.
Abstract Summary: Scientists did a study to see if too much salt in the body's tissues is linked to being overweight and having trouble with insulin, which is a problem for people with diabetes. They looked at 30 people who were overweight and 53 people who were not, checking how well their bodies used insulin and how much salt was in their muscles and skin. They found that in overweight people, the more salt there was in their muscles and skin, the harder it was for their bodies to use insulin. They also noticed that when there was more inflammation in the body, the salt had an even bigger effect on insulin problems. This study suggests that too much salt in the body might help cause insulin issues in overweight people, but more research is needed to be sure.

Parsing within & between-person dynamics of therapy homework completion and clinical symptoms in two cognitive behavioral treatments for adults with anhedonia.
Behav Res Ther.
2023 Jul;
166:104322.
Abstract: Homework is a key theoretical component of cognitive-behavioral therapies, however, the effects of homework on clinical outcomes have largely been evaluated between-persons rather than within-persons. The effects of homework completion on treatment response were examined in a randomized trial comparing Behavioral Activation Treatment for Anhedonia (BATA, n = 38), a novel psychotherapy, to Mindfulness-Based Cognitive Therapy (MBCT, n=35). The primary endpoint was consummatory reward sensitivity, measured weekly by the Snaith Hamilton Pleasure Scale (SHAPS), up to 15 weeks. Multilevel models evaluated change in SHAPS scores over time and the effects of clinician-reported and participant-reported homework. BATA and MBCT resulted in significant, equivalent reductions in SHAPS scores. Unexpectedly, participants who completed greater mean total amounts of homework did not improve at a faster rate (i.e., no between-person effect). However, sessions with greater than average participant-reported homework completion were associated with greater than average reductions in SHAPS scores (i.e., a within-person effect). For clinician-reported homework, this effect was only evident within the BATA condition. This study shows psychotherapy homework completion relates to symptomatic improvement in cognitive-behavioral treatments for anhedonia when session-to-session changes are examined within-person. On the contrary, we found no evidence that total homework completion predicted greater improvements between-person. When possible, psychotherapy researchers should evaluate their constructs of interest across multiple sessions (not just pre/post) to allow more direct tests of hypotheses predicted by theoretical models of individual change processes.
Abstract Summary: Scientists did a study to see if doing homework from therapy helps people feel more joy in life. They had two groups: one did an activity-focused therapy, and the other did a mindfulness therapy. They checked how much pleasure people felt every week for 15 weeks. They found that both therapies helped people feel better, but the amount of homework didn't always make a big difference. If someone did more homework than usual for them, they felt even better after that session, but doing a lot of homework overall didn't mean they felt better than others. This was especially true for the activity-focused therapy. The study tells us that for people getting therapy, it might help to focus on doing homework for each session rather than worrying about doing a lot of homework all the time.

Nicotine receptor partial agonists for smoking cessation.

Abstract: Nicotine receptor partial agonists may help people to stop smoking by a combination of maintaining moderate levels of dopamine to counteract withdrawal symptoms (acting as an agonist) and reducing smoking satisfaction (acting as an antagonist). This is an update of a Cochrane Review first published in 2007. To assess the effectiveness of nicotine receptor partial agonists, including varenicline and cytisine, for smoking cessation. We searched the Cochrane Tobacco Addiction Group's Specialised Register in April 2022 for trials, using relevant terms in the title or abstract, or as keywords. The register is compiled from searches of CENTRAL, MEDLINE, Embase, and PsycINFO. SELECTION CRITERIA: We included randomised controlled trials that compared the treatment drug with placebo, another smoking cessation drug, e-cigarettes, or no medication. We excluded trials that did not report a minimum follow-up period of six months from baseline. We followed standard Cochrane methods. Our main outcome was abstinence from smoking at longest follow-up using the most rigorous definition of abstinence, preferring biochemically validated rates where reported. We pooled risk ratios (RRs), using the Mantel-Haenszel fixed-effect model. We also reported the number of people reporting serious adverse events (SAEs). We included 75 trials of 45,049 people; 45 were new for this update. We rated 22 at low risk of bias, 18 at high risk, and 35 at unclear risk. We found moderate-certainty evidence (limited by heterogeneity) that cytisine helps more people to quit smoking than placebo (RR 1.30, 95% confidence interval (CI) 1.15 to 1.47; I = 83%; 4 studies, 4623 participants), and no evidence of a difference in the number reporting SAEs (RR 1.04, 95% CI 0.78 to 1.37; I = 0%; 3 studies, 3781 participants; low-certainty evidence). SAE evidence was limited by imprecision. We found no data on neuropsychiatric or cardiac SAEs. We found high-certainty evidence that varenicline helps more people to quit than placebo (RR 2.32, 95% CI 2.15 to 2.51; I = 60%, 41 studies, 17,395 participants), and moderate-certainty evidence that people taking varenicline are more likely to report SAEs than those not taking it (RR 1.23, 95% CI 1.01 to 1.48; I = 0%; 26 studies, 14,356 participants). While point estimates suggested increased risk of cardiac SAEs (RR 1.20, 95% CI 0.79 to 1.84; I = 0%; 18 studies, 7151 participants; low-certainty evidence), and decreased risk of neuropsychiatric SAEs (RR 0.89, 95% CI 0.61 to 1.29; I = 0%; 22 studies, 7846 participants; low-certainty evidence), in both cases evidence was limited by imprecision, and confidence intervals were compatible with both benefit and harm. Pooled results from studies that randomised people to receive cytisine or varenicline showed that more people in the varenicline arm quit smoking (RR 0.83, 95% CI 0.66 to 1.05; I = 0%; 2 studies, 2131 participants; moderate-certainty evidence) and reported SAEs (RR 0.67, 95% CI 0.44 to 1.03; I = 45%; 2 studies, 2017 participants; low-certainty evidence). However, the evidence was limited by imprecision, and confidence intervals incorporated the potential for benefit from either cytisine or varenicline. We found no data on neuropsychiatric or cardiac SAEs. We found high-certainty evidence that varenicline helps more people to quit than bupropion (RR 1.36, 95% CI 1.25 to 1.49; I = 0%; 9 studies, 7560 participants), and no clear evidence of difference in rates of SAEs (RR 0.89, 95% CI 0.61 to 1.31; I = 0%; 5 studies, 5317 participants), neuropsychiatric SAEs (RR 1.05, 95% CI 0.16 to 7.04; I = 10%; 2 studies, 866 participants), or cardiac SAEs (RR 3.17, 95% CI 0.33 to 30.18; I = 0%; 2 studies, 866 participants). Evidence of harms was of low certainty, limited by imprecision. We found high-certainty evidence that varenicline helps more people to quit than a single form of nicotine replacement therapy (NRT) (RR 1.25, 95% CI 1.14 to 1.37; I = 28%; 11 studies, 7572 participants), and low-certainty evidence, limited by imprecision, of fewer reported SAEs (RR 0.70, 95% CI 0.50 to 0.99; I = 24%; 6 studies, 6535 participants). We found no data on neuropsychiatric or cardiac SAEs. We found no clear evidence of a difference in quit rates between varenicline and dual-form NRT (RR 1.02, 95% CI 0.87 to 1.20; I = 0%; 5 studies, 2344 participants; low-certainty evidence, downgraded because of imprecision). While pooled point estimates suggested increased risk of SAEs (RR 2.15, 95% CI 0.49 to 9.46; I = 0%; 4 studies, 1852 participants) and neuropsychiatric SAEs (RR 4.69, 95% CI 0.23 to 96.50; I not estimable as events only in 1 study; 2 studies, 764 participants), and reduced risk of cardiac SAEs (RR 0.32, 95% CI 0.01 to 7.88; I not estimable as events only in 1 study; 2 studies, 819 participants), in all three cases evidence was of low certainty and confidence intervals were very wide, encompassing both substantial harm and benefit. Cytisine and varenicline both help more people to quit smoking than placebo or no medication. Varenicline is more effective at helping people to quit smoking than bupropion, or a single form of NRT, and may be as or more effective than dual-form NRT. People taking varenicline are probably more likely to experience SAEs than those not taking it, and while there may be increased risk of cardiac SAEs and decreased risk of neuropsychiatric SAEs, evidence was compatible with both benefit and harm. Cytisine may lead to fewer people reporting SAEs than varenicline. Based on studies that directly compared cytisine and varenicline, there may be a benefit from varenicline for quitting smoking, however further evidence could strengthen this finding or demonstrate a benefit from cytisine. Future trials should test the effectiveness and safety of cytisine compared with varenicline and other pharmacotherapies, and should also test variations in dose and duration. There is limited benefit to be gained from more trials testing the effect of standard-dose varenicline compared with placebo for smoking cessation. Further trials on varenicline should test variations in dose and duration, and compare varenicline with e-cigarettes for smoking cessation.
Abstract Summary: Scientists did a big study to see if two drugs, called cytisine and varenicline, can help people stop smoking. They looked at a lot of other studies where people were given these drugs, a fake pill (placebo), or other stop-smoking treatments. They wanted to know if these drugs made it easier for people to quit smoking and if they caused any serious problems (like heart issues or mood changes).
They found that both cytisine and varenicline helped more people quit smoking than a fake pill. Varenicline was even better at helping people stop than another drug called bupropion or just using one type of nicotine patch or gum. But, some people taking varenicline had serious problems more often than those who didn't take it. The scientists aren't sure if these problems are really caused by the drug or not.
In the end, they think these drugs are good for helping people quit smoking, but they want to do more research to be really sure about how safe they are and if one is better than the other. They also think we don't need more studies comparing varenicline to a fake pill because we already know it works. Instead, they suggest looking at different amounts of the drug and how long people should take it, and comparing it to e-cigarettes.

Abstract: Recruiting to multi-site trials is challenging, particularly when striving to ensure the randomized sample is demographically representative of the larger disease-suffering population. While previous studies have reported disparities by race and ethnicity in enrollment and randomization, they have not typically investigated whether disparities exist in the recruitment process prior to consent. To identify participants most likely to be eligible for a trial, study sites frequently include a prescreening process, generally conducted by telephone, to conserve resources. Collection and analysis of such prescreening data across sites could provide valuable information to improve understanding of recruitment intervention effectiveness, including whether traditionally underrepresented participants are lost prior to screening. We developed an infrastructure within the National Institute on Aging (NIA) Alzheimer's Clinical Trials Consortium (ACTC) to centrally collect a subset of prescreening variables. Prior to study-wide implementation in the AHEAD 3-45 study (NCT NCT04468659), an ongoing ACTC trial recruiting older cognitively unimpaired participants, we completed a vanguard phase with seven study sites. Variables collected included age, self-reported sex, self-reported race, self-reported ethnicity, self-reported education, self-reported occupation, zip code, recruitment source, prescreening eligibility status, reason for prescreen ineligibility, and the AHEAD 3-45 participant ID for those who continued to an in-person screening visit after study enrollment. Each of the sites was able to submit prescreening data. Vanguard sites provided prescreening data on a total of 1029 participants. The total number of prescreened participants varied widely among sites (range 3-611), with the differences driven mainly by the time to receive site approval for the main study. Key learnings instructed design/informatic/procedural changes prior to study-wide launch. Centralized capture of prescreening data in multi-site clinical trials is feasible. Identifying and quantifying the impact of central and site recruitment activities, prior to participants signing consent, has the potential to identify and address selection bias, instruct resource use, contribute to effective trial design, and accelerate trial enrollment timelines.
Abstract Summary: Scientists are trying to make sure that when they test new medicines, the group of people in the study looks like the group of people who have the sickness the medicine is for. Sometimes, not everyone has the same chance to be in these studies. The scientists did a special part of a big study to see who gets asked to join before they even say yes. They looked at things like how old people are, if they are a boy or a girl, what race they are, and where they live. They did this in seven places and learned from 1029 people. They found out that they can collect this information from many places and it helps them understand who might not be getting a fair chance to join the study. This can help them make the study better and faster, and make sure more kinds of people can be in it.

Abstract: Obesity is an independent risk factor for cardiovascular disease (CVD) in patients with type 2 diabetes (T2D). However, it is not known to what extent weight fluctuations might be associated with adverse outcomes. We aimed at assessing the associations between extreme weight changes and cardiovascular outcomes in two large randomised controlled trials of canagliflozin in patients with T2D and high cardiovascular (CV) risk. In the study populations of the CANVAS Program and CREDENCE trials, weight change was evaluated between randomization and week 52-78, defining subjects in the top 10% of the entire distribution of weight changes as gainers, subjects in the bottom 10% as losers and the remainder as stable. Univariate and multivariate Cox proportional hazards models were used to test the associations between weight changes categories, randomised treatment and covariates with heart failure hospitalisation (hHF) and the composite of hHF and CV death. Median weight gain was 4.5 kg in gainers and median weight loss was 8.5 kg in losers. The clinical phenotype of gainers as well as that of losers were similar to that of stable subjects. Weight change within each category was only slightly larger with canagliflozin than placebo. In both trials, gainers and losers had a higher risk of hHF and of hHF/CV death compared with stable at univariate analysis. In CANVAS, this association was still significant by multivariate analysis for hHF/CV death in both gainers and losers vs. stable (hazard ratio - HR 1.61 [95% confidence interval - CI: 1.20-2.16] and 1.53 [95% CI 1.14-2.03] respectively). Results were similar in CREDENCE for gainers vs. stable (adjusted HR for hHF/CV death 1.62 [95% CI 1.19-2.16]) CONCLUSIONS: Extremes of weight gain or loss were independently associated with a higher risk of the composite of hHF and CV death. In patients with T2D and high CV risk, large changes in body weight should be carefully assessed in view of individualised management. CANVAS ClinicalTrials.gov number: NCT01032629. CREDENCE ClinicalTrials.gov number: NCT02065791.
Abstract Summary: Doctors wanted to see if gaining or losing a lot of weight quickly affects heart health in people with type 2 diabetes who are already at risk for heart problems. They looked at two big studies where people took a diabetes medicine called canagliflozin. They checked the weight of these people after about a year and put them into three groups: those who gained a lot of weight, those who lost a lot of weight, and those whose weight stayed the same.
They found that people who gained or lost a lot of weight had a higher chance of going to the hospital for heart failure or even dying from heart problems compared to those whose weight didn't change much. This means that for people with type 2 diabetes who might have heart issues, it's important to watch out for big weight changes and talk to a doctor about the best way to stay healthy.

Abstract: Non-alcoholic fatty liver disease (NAFLD) is a common comorbidity that leads to poor outcomes in people at high risk for development of type 2 diabetes (T2D). Vitamin D is a possible mediator. In the vitamin D and type 2 diabetes study (D2d), we investigated the relationship of baseline indices of NAFLD with incident T2D and whether the effect of vitamin D on diabetes was modified by NAFLD. Cross-sectional associations of indices of NAFLD with glycemia and vitamin D status were assessed in 3972 individuals screened for the D2d study. In those with prediabetes randomized to vitamin D or placebo (n = 2423), we examined longitudinal associations of NAFLD indices with incident T2D. We used validated non-invasive scores to assess steatosis [(hepatic steatosis index (HSI); NAFLD-liver fat score (NAFLD-LFS)] and advanced fibrosis [fibrosis-4 (FIB-4) index; AST to Platelet Ratio Index (APRI)]. Eighty-five percent of screened participants had likely steatosis by HSI and 71 % by NAFLD-LFS; 3 % were likely to have advanced fibrosis by FIB-4 and 1.2 % by APRI. FIB-4 indicated that 20.4 % of individuals require further follow up to assess liver health. Steatosis and fibrosis scores were higher among participants with worse glycemia. The NAFLD-LFS and APRI predicted development of diabetes (hazard ratios [95%CI] 1.35 [1.07, 1.70]; P = 0.012) and 2.36 (1.23, 4.54; P = 0.010), respectively). The effect of vitamin D on diabetes risk was not modified by baseline NAFLD indices. Individuals with likely steatosis had a smaller increase in serum 25-hydroxyvitamin D level in response to vitamin D than those without steatosis. The predicted high prevalence of steatosis, the need for further fibrosis workup, and the relationship between liver health and incident T2D suggest that routine screening with clinically accessible scores may be an important strategy to reduce disease burden.
Abstract Summary: Scientists did a study to see if there's a link between liver health and getting type 2 diabetes, which is a kind of sugar sickness. They also wanted to know if vitamin D could change the chances of getting diabetes for people with liver problems. They looked at 3972 people who might get diabetes and checked their liver health using special scores. They found that a lot of these people had signs of fat in their liver and a few might have serious liver damage. They also saw that people with worse sugar levels in their blood had worse liver scores. Over time, they noticed that people with certain liver scores were more likely to get diabetes. Vitamin D didn't really change the risk of getting diabetes, but people with liver fat didn't get as much vitamin D in their blood when they took supplements. The study suggests that doctors should check people's liver health to help prevent diabetes.

Abstract: Patient-reported outcomes can capture domains that are meaningful to patients, such as life engagement in major depressive disorder (MDD), which reflects life fulfillment, well-being, and participation in valued and meaningful activities. This analysis investigated the effects of brexpiprazole adjunct to antidepressant treatment (ADT) on patient life engagement over the short and long term, using the 10-item Inventory of Depressive Symptomatology Self-Report (IDS-SR) Life Engagement subscale. Short-term data were pooled from three 6-week, randomized, double-blind studies of ADT + brexpiprazole 2-3 mg/day versus ADT + placebo in adult outpatients with MDD (DSM-IV-TR criteria) and inadequate response to ADTs. Long-term data were from a 26-52-week, open-label extension study of ADT + brexpiprazole 0.5-3 mg/day. Over 6 weeks, ADT + brexpiprazole (n = 579) showed greater improvement in IDS-SR Life Engagement subscale score than ADT + placebo (n = 583), with a least squares mean difference of -1.19 (95% confidence limits: -1.78, -0.59; p = 0.0001; Cohen's d effect size: 0.23). Greater improvement for ADT + brexpiprazole versus ADT + placebo (p < 0.05) was also observed on eight life engagement items, with effect sizes ranging from 0.12 to 0.24. In the long-term study, mean (standard deviation) IDS-SR Life Engagement subscale score changed by -2.4 (4.9) points to Week 26 (n = 2047), and -3.7 (5.3) points to Week 52 (n = 768), with mean improvements on all ten items. Beyond its efficacy on depressive symptoms, adjunctive brexpiprazole may improve patient life engagement, thereby helping patients with MDD to achieve personally meaningful functional outcomes.
Abstract Summary: Scientists did a study to see if a medicine called brexpiprazole could help adults with major depression feel more involved in life when taken with their usual antidepressants. They checked if patients felt more fulfilled and took part in activities they valued. They used a special questionnaire to measure this. In the first part of the study, they compared two groups for 6 weeks: one took brexpiprazole with their antidepressants, and the other took a fake pill with their antidepressants. The brexpiprazole group felt better and more engaged in life. In the second part, they watched people take brexpiprazole with their antidepressants for up to a year, and those people continued to feel more engaged in life. This research suggests that brexpiprazole might help people with depression not only feel less sad but also enjoy life more.

Positive Psychological Intervention Effects on Depression: Positive Emotion Does Not Mediate Intervention Impact in a Sample with Elevated Depressive Symptoms.
Affect Sci.

4(1):163-173.
Abstract: Positive psychological interventions (PPIs), programs that specifically target positive emotions, cognitions, and behaviors, have been shown to reduce depression and improve other aspects of psychological well-being. However, potential pathways linking PPIs to better outcomes have been under-explored. In this paper, we report the results of a randomized trial of a self-guided online delivered PPI called MARIGOLD (Mobile Affect Regulation Intervention with the Goal of Lowering Depression). Participants with elevated depression were randomized to receive MARIGOLD ( = 539) or an emotion reporting control condition ( = 63). In addition to testing direct effects of the intervention on depressive symptoms, we explored whether positive or negative emotion-operationalized as past day, past week, reactivity, or flexibility-mediated the intervention impact on depression. Results demonstrated that participants in the MARIGOLD condition had reduced depressive symptoms compared to controls and, although the effect did not reach statistical significance, reductions in past day negative emotion appeared to mediate this effect. Contrary to hypotheses, the intervention did not increase positive emotion compared to the control condition. Discussion focuses on the need for future studies to continue investigating the mechanisms of action for PPIs with emphasis on theoretically-based measurement and operationalization of emotion and other potential mediators to maximize the ultimate impact of PPIs on psychological well-being. Clinical Trials registration #NCT02861755.
Abstract Summary: Scientists did a study to see if a special online program could help people feel less sad. This program, called MARIGOLD, is designed to make people think and act in a happier way. They had some people try MARIGOLD and others just write about their feelings. They wanted to see if the program made people less sad and if it changed their emotions. They found out that the people who used MARIGOLD were less sad than the ones who didn't. But, the program didn't really make them feel happier. The study suggests that we need to learn more about how programs like MARIGOLD can help people feel better.

Abstract: Efforts to minimize medication risks among older adults include avoidance of potentially inappropriate medications (PIMs). However, most PIMs research has focused on older people in aged or inpatient care, creating an evidence gap for community-dwelling older adults. To address this gap, we investigated the impact of PIMs use in the ASPirin in Reducing Events in the Elderly (ASPREE) clinical trial cohort. Analysis included 19,114 community-dwelling ASPREE participants aged 70+ years (65+ if US minorities) without major cardiovascular disease, cognitive impairment, or significant physical disability. PIMs were defined according to a modified 2019 AGS Beers Criteria. Cox proportional-hazards regression models were used to estimate the association between baseline PIMs exposure and disability-free survival, death, incident dementia, disability, and hospitalization, with adjustment for sex, age, country, years of education, frailty, average gait speed, and comorbidities. At baseline, 7396 (39% of the total) participants were prescribed at least one PIM. Compared with those unexposed, participants on a PIM at baseline were at an increased risk of persistent physical disability (adjusted hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.21, 1.80) and hospitalization (adjusted HR 1.26, 95% CI 1.20, 1.32), but had similar rates of disability-free survival (adjusted HR 1.02; 95% CI 0.93, 1.13) and death (adjusted HR 0.92, 95% CI 0.81, 1.05). These effects did not vary by polypharmacy status in interaction analyses. PIMs exposure was associated with higher risk of disability followed by hospitalization (adjusted HR 1.92, 95% CI 1.25, 2.96) as well as vice versa (adjusted HR 1.54, 95% CI 1.15, 2.05). PPIs, anti-psychotics and benzodiazepines, were associated with increased risk of disability. PIMs exposure is associated with subsequent increased risk of both incident disability and hospitalization. Increased risk of disability prior to hospitalization suggests that PIMs use may start the disability cascade in healthy older adults. Our findings emphasize the importance of caution when prescribing PIMs to older adults in otherwise good health.
Abstract Summary: Scientists did a study to see if certain medicines might not be good for older people living at home. They looked at over 19,000 older adults who were pretty healthy and didn't have serious heart problems, trouble thinking, or trouble moving around. They checked what medicines these people were taking and followed them to see if they had any health problems like getting hurt and not being able to move well, having to go to the hospital, or getting dementia.
They found that about 39% of these older adults were taking at least one medicine that might not be good for them. These adults had a higher chance of getting hurt and not being able to move well, and they also went to the hospital more often. But these medicines didn't make them die sooner or live without health problems any less than other people.
The study showed that some medicines, like stomach acid pills, antipsychotics, and anxiety pills, could make it more likely for older people to get hurt and not be able to move well. So, the study tells us that doctors should be really careful when giving these kinds of medicines to older people who are otherwise healthy.

Abstract: The purpose of this study was to investigate associations among behavioral and cognitive-affective features of stuttering in preschool-age children who stutter, and the extent to which participants may or may not cluster together based on multiple indices of stuttering. Participants were 296 preschool-age children who stutter (mean age 47.9 months). Correlation and regression analyses, as well as k-means cluster analyses were conducted between and among several indices of stuttering: frequency of stuttering- and non-stuttering-like disfluencies (SLDs and NSLDs), ratios of repetitions and prolongations/blocks out of total number of SLDs, associated nonspeech behaviors, duration of stuttering events, KiddyCAT scores (Vanryckeghem & Brutten, 2007), and a TOCS parent-rated scale (Gillam et al., 2009). For preschool-age children who stutter, most indices of overt stuttering behaviors were intercorrelated (e.g., more SLDs were associated with higher ratio of repetitions). Self-reported KiddyCAT scores (Vanryckeghem & Brutten, 2007) were largely not significantly associated with stuttering. Cluster analyses yielded two participant groupings: a larger group with less prominent stuttering features and a smaller group with more prominent features. This study contributes to an increasingly comprehensive and nuanced understanding of the heterogeneous features of stuttering and their development in preschool-age children. Findings show strong intercorrelations between measures of stuttering behaviors, but more tenuous relationships between behaviors and cognitive-affective reactions to stuttering. Exploration of clusters of characteristics within this population revealed potential opportunities for future research.
Abstract Summary: Scientists did a study to learn more about how preschool kids who have trouble speaking smoothly (stutter) behave and feel. They looked at 296 young kids who stutter to see if they had things in common. They checked how often the kids repeated sounds or got stuck, if they made any extra movements while talking, how long the stuttering lasted, and how the kids felt about talking. They found that the way kids stutter is often connected—for example, kids who repeat sounds a lot might also get stuck more. But how kids feel about their talking didn't always match with their stuttering. They also discovered that the kids could be split into two groups: one big group with less noticeable stuttering and a smaller group with more noticeable stuttering. This research helps us understand that not all kids who stutter are the same, and it can help us figure out better ways to help them.

PLoS Negl Trop Dis.
2023 Apr;
17(4):e0011229.
Abstract: Plasmodium vivax is a major challenge for malaria control due to its wide geographic distribution, high frequency of submicroscopic infections, and ability to induce relapses due to the latent forms present in the liver (hypnozoites). Deepening our knowledge of parasite biology and its molecular components is key to develop new tools for malaria control and elimination. This study aims to investigate and characterize a P. vivax protein (PvVir14) for its role in parasite biology and its interactions with the immune system. We collected sera or plasma from P.vivax-infected subjects in Brazil (n = 121) and Cambodia (n = 55), and from P. falciparum-infected subjects in Mali (n = 28), to assess antibody recognition of PvVir14. Circulating antibodies against PvVir14 appeared in 61% and 34.5% of subjects from Brazil and Cambodia, respectively, versus none (0%) of the P. falciparum-infected subjects from Mali who have no exposure to P. vivax. IgG1 and IgG3 most frequently contributed to anti-PvVir14 responses. PvVir14 antibody levels correlated with those against other well-characterized sporozoite/liver (PvCSP) and blood stage (PvDBP-RII) antigens, which were recognized by 7.6% and 42% of Brazilians, respectively. Concerning the cellular immune profiling of Brazilian subjects, PvVir14 seroreactive individuals displayed significantly higher levels of circulating atypical (CD21- CD27-) B cells, raising the possibility that atypical B cells may be contribute to the PvVir14 antibody response. When analyzed at a single-cell level, the B cell receptor gene hIGHV3-23 was only seen in subjects with active P.vivax infection where it comprised 20% of V gene usage. Among T cells, CD4+ and CD8+ levels differed (lower and higher, respectively) between subjects with versus without antibodies to PvVir14, while NKT cell levels were higher in those without antibodies. Specific B cell subsets, anti-PvVir14 circulating antibodies, and NKT cell levels declined after treatment of P. vivax. This study provides the immunological characterization of PvVir14, a unique P. vivax protein, and possible association with acute host's immune responses, providing new information of specific host-parasite interaction. Trial registration: TrialClinicalTrials.gov Identifier: NCT00663546 & ClinicalTrials.gov NCT02334462.
Abstract Summary: Scientists are studying a special protein from a germ that causes a type of malaria. This germ is tricky because it can hide in the liver and make people sick again after they seem to get better. The researchers looked at blood from people in Brazil, Cambodia, and Mali to see if their bodies made fighters, called antibodies, against this protein. They found that many people in Brazil and some in Cambodia had these fighters, but none in Mali did because the germ isn't found there.
They also discovered that certain blood cells that help make antibodies were more common in people who had these fighters. After treating the malaria, the number of these cells and fighters went down. This study helps us understand how our bodies try to fight off this type of malaria and could help make new ways to stop it.

Abstract: To assess the relationship of adherence and pregnancy in participants using an estetrol and drospirenone combined oral contraceptive. We performed a secondary analysis for which we pooled data from two parallel, multicenter, phase 3 trials (United States and Canada, Europe and Russia) that enrolled participants 16-50 years of age to receive estetrol 15 mg and drospirenone 3 mg in a 24 hormone and four placebo pills regimen for up to 13 cycles. Participants reported pill intake, sexual intercourse, and other contraceptive use on paper diaries. We limited this efficacy analysis to at-risk cycles (one or more reported acts of intercourse and no other contraceptive use) in participants 16-35 years of age at screening. We excluded cycles with other contraceptive use unless pregnancy occurred in that cycle. We assessed primarily the relationship between number of pills not taken per cycle and pregnancies and, secondarily, when pregnancies occurred during product use with a test for trend and χ 2 analyses as appropriate. Among 2,837 participants in this analysis, 31 on-treatment pregnancies occurred during 26,455 at-risk cycles. Pregnancies occurred in 0.09%, 0.25%, 0.83%, and 1.6% of cycles in which participants reported they took all hormone pills (n=25,613 cycles) or did not take one (n=405 cycles), two (n=121 cycles), and more than two (n=314 cycles) hormone-containing pills, respectively ( P <.001). No pregnancies occurred in 2,216 cycles when one or more pills were missed and missed-pill instructions were followed. All pregnancies related to not taking pills occurred in the first three cycles. Pregnancy rates ranged from 0% to 0.21% per cycle with no significant trend by cycle ( P =.45). Pregnancy occurs more frequently when combined oral contraceptive users report not taking all hormone-containing pills per 28-day cycle and exceeds 1% only when more than two pills are not taken. Pregnancies in participants who reported missed pills occurred only when missed-pill instructions were not followed. A 0.09% pregnancy risk per cycle among users of a 24 hormone and four placebo pills formulation who report taking all pills likely approximates a true method-failure rate.

Abstract Summary: Scientists studied how well a new birth control pill worked when people didn't take it exactly as they should. They looked at information from two big studies that included women aged 16 to 50 from different countries. These women took a pill with two special ingredients, estetrol and drospirenone, and wrote down when they took the pill, had sex, and if they used other birth control methods.
The researchers focused on women aged 16 to 35 who had sex without using other birth control and didn't always take their pill. They found that when women missed more than two pills in a month, the chance of getting pregnant went up a lot. But if they followed the instructions on what to do when they missed a pill, they didn't get pregnant. Most of the time, if someone got pregnant, it was because they didn't take their pills correctly in the first three months.
The study shows that this birth control pill works really well if you take it every day, but it's super important to follow the instructions, especially if you forget to take a pill.

Effect of intratrial mean 25(OH)D concentration on diabetes risk, by race and weight: an ancillary analysis in the D2d study.
Am J Clin Nutr.
2023 Jul;
118(1):59-67.
Abstract: Higher serum 25-hydroxyvitamin D [25(OH)D] is associated with lower type 2 diabetes risk. 25(OH)D varies due to skin pigmentation and weight. This analysis aims to determine whether the effect of vitamin D differs among people of color and those with overweight/obesity (who have higher diabetes risk) compared with individuals who are White or have normal weight. The D2d study is a randomized clinical trial in people with prediabetes that tested the effects of daily vitamin D 4000 IU vs. placebo on diabetes risk (median followup 2.5 y). We compared baseline and intratrial mean 25(OH)D concentrations, defined as the mean of all available annual 25(OH)D values, among groups defined by self-reported race and body mass index (BMI). We used Cox proportional hazards models to assess the associations between intratrial mean 25(OH)D and diabetes risk by race- and BMI-based groups. Asian (n=130), Black (n=616), and White (n=1616) participants were included. Both baseline and intratrial mean 25(OH)D concentrations differed significantly by race groups (both P < 0.001) and were lower in Asian and Black vs. White participants, and in those with higher vs. lower BMI adjusted for race (both P < 0.001). Compared with those with lower concentrations, Black and White participants with intratrial mean 25(OH)D ≥ 40 ng/mL had significantly reduced diabetes risk [HR (95% CI): Black: 0.51 (0.29, 0.92); White: 0.42 (0.30, 0.60)] and with a similar reduction in diabetes risk among Asian participants: 0.39 (0.14, 1.11). Compared with those with lower concentrations, participants with baseline BMI < 40 kg/m who achieved intratrial mean 25(OH)D concentrations ≥ 40 ng/mL had a significantly reduced diabetes risk. There was no statistically significant interaction between intratrial 25(OH)D and race or between intratrial 25(OH)D and BMI on diabetes risk. Among people with prediabetes, particularly for Black and White race groups and those with BMI < 40 kg/m, the optimal 25(OH)D concentration may be ≥ 40 ng/mL to optimize diabetes-prevention efforts. This trial was registered at clinicaltrials.gov as NCT01942694.
Abstract Summary: Scientists did a study to see if taking vitamin D could help people with a little high blood sugar (called prediabetes) avoid getting type 2 diabetes. They gave some people vitamin D pills and others fake pills and watched them for about 2.5 years. They were especially interested in people with different skin colors and weights because these can affect how much vitamin D someone has in their body and their risk for diabetes.
They found that people who had more vitamin D in their blood, especially those who were Black or White and not too overweight, were less likely to get diabetes. For all groups, having a vitamin D level of at least 40 in their blood seemed to be good for lowering the risk of diabetes.
This study tells us that having enough vitamin D might be important for people who are at risk of getting diabetes, and it could help them stay healthier.

2023 Jun 1;
18(6):748-758.
Abstract: In the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, the sodium-glucose cotransporter-2 (SGLT2) inhibitor canagliflozin improved kidney and cardiovascular outcomes and reduced the rate of estimated glomerular filtration decline (eGFR slope) in patients with type 2 diabetes and CKD. In other clinical trials of patients with CKD or heart failure, the protective effects of SGLT2 inhibitors on eGFR slope were greater in participants with versus participants without type 2 diabetes. This post hoc analysis of the CREDENCE trial assessed whether the effects of canagliflozin on eGFR slope varied according to patient subgroups by baseline glycated hemoglobin A1c (HbA1c). CREDENCE ( ClinicalTrials.gov [ NCT02065791 ]) was a randomized controlled trial in adults with type 2 diabetes with an HbA1c of 6.5%-12.0%, an eGFR of 30-90 ml/min per 1.73 m 2 , and a urinary albumin-to-creatinine ratio of 300-5000 mg/g. Participants were randomly assigned to canagliflozin 100 mg once daily or placebo. We studied the effect of canagliflozin on eGFR slope using linear mixed-effects models. The annual difference in total eGFR slope was 1.52 ml/min per 1.73 m 2 (95% confidence interval [CI], 1.11 to 1.93) slower in participants randomized to canagliflozin compared with placebo. The rate of eGFR decline was faster in those with poorer baseline glycemic control. The mean difference in total eGFR slope between canagliflozin and placebo was greater in participants with poorer baseline glycemic control (difference in eGFR slope of 0.39, 1.36, 2.60, 1.63 ml/min per 1.73 m 2 for HbA1c subgroups 6.5%-7.0%, 7.0%-8.0%, 8.0%-10.0%, 10.0%-12.0%, respectively; Pinteraction = 0.010). The mean difference in change from baseline in urinary albumin-to-creatinine ratio between participants randomized to canagliflozin and placebo was smaller in patients with baseline HbA1c 6.5%-7.0% (-17% [95% CI, -28 to -5]) compared with those with an HbA1c of 7.0%-12% (-32% [95% CI, -40 to -28]; Pinteraction = 0.03). The effect of canagliflozin on eGFR slope in patients with type 2 diabetes and CKD was more pronounced in patients with higher baseline HbA1c, partly because of the more rapid decline in kidney function in these individuals. Evaluation of the Effects of Canagliflozin on Renal and Cardiovascular Outcomes in Participants With Diabetic Nephropathy (CREDENCE), NCT02065791.
Abstract Summary: Scientists did a study called CREDENCE to see if a medicine called canagliflozin helps people with type 2 diabetes and kidney problems. They gave some people the medicine and others a placebo, which is like a sugar pill with no medicine in it. They found that the medicine slowed down the worsening of kidney function, especially in people who had higher blood sugar levels to start with. This is important because it shows that this medicine can help protect the kidneys of people with diabetes, and it might work even better for those who have more trouble controlling their blood sugar.

Abstract: Given the importance of self-management in type 2 diabetes mellitus (T2DM), a major aspect of health is providing diabetes self-management education and support. Known barriers include access, availability, and the lack of follow through on referral to education programs. Virtual education and support have increased in use over the last few years. The purpose of the Diabetes Learning in a Virtual Environment (LIVE) study was to compare the effects of the LIVE intervention (educational 3D world) to a diabetes self-management education and support control website on diet and physical activity behaviors and behavioral and metabolic outcomes in adults with T2DM over 12 months. The LIVE study was a 52-week multisite randomized controlled trial with longitudinal repeated measures. Participants were randomized to LIVE (n=102) or a control website (n=109). Both contained the same educational materials, but the virtual environment was synchronous and interactive, whereas the control was a flat website. Data were collected at baseline and 3, 6, and 12 months using surveys and clinical, laboratory, and Fitbit measures. Descriptive statistics included baseline characteristics and demographics. The effects of the intervention were initially examined by comparing the means and SDs of the outcomes across the 4 time points between study arms, followed by multilevel modeling on trajectories of the outcomes over the 12 months. This trial included 211 participants who consented. The mean age was 58.85 (SD 10.1) years, and a majority were White (127/211, 60.2%), non-Hispanic (198/211, 93.8%), married (107/190, 56.3%), and female (125/211, 59.2%). Mean hemoglobin A (HbA) level at baseline was 7.64% (SD 1.79%) and mean BMI was 33.51 (SD 7.25). We examined weight loss status versus randomized group, where data with no weight change were eliminated, and the LIVE group experienced significantly more weight loss than the control group (P=.04). There were no significant differences between groups in changes in physical activity and dietary outcomes (all P>.05), but each group showed an increase in physical activity. Both groups experienced a decrease in mean HbA level, systolic and diastolic blood pressure, cholesterol, and triglycerides over the course of 12 months of study participation, including those participants whose baseline HbA level was 8.6% or higher. This study confirmed that there were minor positive changes on glycemic targets in both groups over the 12-month study period; however, the majority of the participants began with optimal HbA levels. We did find clinically relevant metabolic changes in those who began with an HbA level >8.6% in both groups. This study provided a variety of resources to our participants in both study groups, and we conclude that a toolkit with a variety of services would be helpful to improving self-care in the future for persons with T2DM. ClinicalTrials.gov NCT02040038; https://clinicaltrials.gov/ct2/show/NCT02040038.
Abstract Summary: Doctors wanted to see if a special online 3D world could help adults with type 2 diabetes take better care of themselves compared to a regular website with the same information. They had 211 people join the study and split them into two groups. One group used the 3D world, and the other group used the regular website. They checked on the participants after 3, 6, and 12 months to see how they were doing with their eating, exercise, and health numbers like blood sugar and cholesterol.
After a year, they found that the people using the 3D world lost a bit more weight than the other group, but both groups got more active and had better health numbers. This was especially true for people who started with higher blood sugar levels. The study showed that having different kinds of help, like the 3D world and the website, can make it easier for people with diabetes to take care of their health.

Cellular senescence and disrupted proteostasis induced by myotube atrophy are prevented with low-dose metformin and leucine cocktail.
Aging (Albany NY).
2023 Mar 20;
15(6):1808-1832.
Abstract: Aging coincides with the accumulation of senescent cells within skeletal muscle that produce inflammatory products, known as the senescence-associated secretory phenotype, but the relationship of senescent cells to muscle atrophy is unclear. Previously, we found that a metformin + leucine (MET+LEU) treatment had synergistic effects in aged mice to improve skeletal muscle structure and function during disuse atrophy. Therefore, the study's purpose was to determine the mechanisms by which MET+LEU exhibits muscle atrophy protection and if this occurs through cellular senescence. C2C12 myoblasts differentiated into myotubes were used to determine MET+LEU mechanisms during atrophy. Additionally, aged mouse single myofibers and older human donor primary myoblasts were individually isolated to determine the translational potential of MET+LEU on muscle cells. MET+LEU (25 + 125 μM) treatment increased myotube differentiation and prevented myotube atrophy. Low concentration (0.1 + 0.5 μM) MET+LEU had unique effects to prevent muscle atrophy and increase transcripts related to protein synthesis and decrease transcripts related to protein breakdown. Myotube atrophy resulted in dysregulated proteostasis that was reversed with MET+LEU and individually with proteasome inhibition (MG-132). Inflammatory and cellular senescence transcriptional pathways and respective transcripts were increased following myotube atrophy yet reversed with MET+LEU treatment. Dasatinib + quercetin (D+Q) senolytic prevented myotube atrophy similar to MET+LEU. Finally, MET+LEU prevented loss in myotube size in alternate models of muscle atrophy as well as in aged myofibers while, in human primary myotubes, MET+LEU prevented reductions in myonuclei fusion. These data support that MET+LEU has skeletal muscle cell-autonomous properties to prevent atrophy by reversing senescence and improving proteostasis.
Abstract Summary: Scientists did a study to see if a mix of two things, metformin and leucine (MET+LEU), could help stop muscles from getting weaker and smaller as people and animals get older. As we age, some of our muscle cells stop working right and create bad stuff that causes inflammation. The researchers wanted to know if MET+LEU could protect muscles by fixing these old cells.
They tested this idea on muscle cells from mice and humans. They found that MET+LEU helped the muscle cells grow and stopped them from shrinking. It also helped the cells make more muscle proteins and break down fewer of them. Even when muscle cells were stressed and started to get old and inflamed, MET+LEU helped them get better.
Another mix, dasatinib and quercetin (D+Q), also stopped the muscle cells from shrinking, just like MET+LEU did. In the end, the study showed that MET+LEU could be a good way to keep muscles strong, especially for older people.

Conflicts hurt: social stress predicts elevated pain and sadness after mild inflammatory increases.

164(9):1985-1994.
Abstract: Individuals respond differently to inflammation. Pain, sadness, and fatigue are common correlates of inflammation among breast cancer survivors. Stress may predict response intensity. This study tested whether breast cancer survivors with greater exposure to acute or chronic social or nonsocial stress had larger increases in pain, sadness, and fatigue during an acute inflammatory response. In total, 156 postmenopausal breast cancer survivors (ages 36-78 years, stage I-IIIA, 1-9 years posttreatment) were randomized to either a typhoid vaccine/saline placebo or the placebo/vaccine sequence, which they received at 2 separate visits at least 1 month apart. Survivors had their blood drawn every 90 minutes for the next 8 hours postinjection to assess levels of interleukin-6 and interleukin-1 receptor antagonist (IL-1Ra). Shortly after each blood draw, they rated their current levels of pain, sadness, and fatigue. Women also completed the Test of Negative Social Exchange to assess chronic social stress and the Trier Inventory of Chronic Stressors screen to index chronic general stress. At each visit, a trained experimenter administered the Daily Inventory of Stressful Events to assess social and nonsocial stress exposure within the past 24 hours. After statistical adjustment for relevant demographic and behavioral covariates, the most consistent results were that survivors who reported more chronic social stress reported more pain and sadness in response to IL-1Ra increases. Frequent and ongoing social stress may sensitize the nervous system to the effects of inflammation, with potential implications for chronic pain and depression risk among breast cancer survivors.
Abstract Summary: Scientists did a study to see if stress makes breast cancer survivors feel more pain, sadness, and tiredness when their bodies are fighting off something like an infection. They worked with 156 women who had been treated for breast cancer. These women were given a shot that made their bodies think they were sick, so the scientists could see how they reacted. The women told the scientists how stressed they were and how they felt every hour and a half after the shot.
The study found that women who had a lot of stress from problems with other people felt more pain and sadness when their bodies were fighting off the pretend sickness. This means that when people who have had breast cancer are stressed a lot, especially by other people, it might make them feel worse when they get sick. This is important because it could help doctors understand why some women have more pain or feel sadder after cancer and how to help them better.

Black Women's Perspectives on Breast Cancer Risk Assessment.

20(3):314-323.
Abstract: The aim of this study was to gather the perspectives of Black women on breast cancer risk assessment through a series of one-on-one interviews. The authors conducted a cross-sectional qualitative study consisting of one-on-one semistructured telephone interviews with Black women in Tennessee between September 2020 and November 2020. Guided by the Health Belief Model, qualitative analysis of interview data was performed in an iterative inductive and deductive approach and resulted in the development of a conceptual framework to depict influences on a woman's decision to engage with breast cancer risk assessment. A total of 37 interviews were completed, and a framework of influences on a woman's decision to engage in breast cancer risk assessment was developed. Study participants identified several emerging themes regarding women's perspectives on breast cancer risk assessment and potential influences on women's decisions to engage with risk assessment. Much of women's decision context was based on risk appraisal (perceived severity of cancer and susceptibility of cancer), emotions (fear and trust), and perceived risks and benefits of having risk assessment. The decision was further influenced by modifiers such as communication, the risk assessment protocol, access to health care, knowledge, and health status. Perceived challenges to follow-up if identified as high risk also influenced women's decisions to pursue risk assessment. Black women in this study identified several barriers to engagement with breast cancer risk assessment. Efforts to overcome these barriers and increase the use of breast cancer risk assessment can potentially serve as a catalyst to address existing breast cancer disparities. Continued work is needed to develop patient-centric strategies to overcome identified barriers.
Abstract Summary: Scientists wanted to understand what Black women think about checking their chances of getting breast cancer. They talked to Black women in Tennessee on the phone from September to November 2020. They asked questions and listened to the women's thoughts and feelings. After talking to 37 women, they found out that women decide whether to check their breast cancer risk based on how serious they think cancer is, how scared they are of getting it, and what they think about the good and bad things that could come from checking their risk. Things like talking to doctors, how easy it is to get to a doctor, what they know about health, and their own health can change their decision. If women think it will be hard to get help if they are at high risk, they might not want to check their risk. The study found that Black women face challenges in deciding to check their breast cancer risk. If these challenges are fixed, it could help reduce the number of Black women who get breast cancer. More work is needed to help women overcome these challenges.

Abstract: Chronic stress alters reward sensitivity and contributes to the emergence of anhedonia. In clinical samples, the perception of stress is a strong predictor of anhedonia. While there is substantial evidence demonstrating psychotherapy reduces perceived stress, little is known regarding the effects of treatment-related decreases in perceived stress on anhedonia. The current study investigated reciprocal relations between perceived stress and anhedonia using a cross-lagged panel model approach in a 15-week clinical trial examining the effects of Behavioral Activation Treatment for Anhedonia (BATA), a novel psychotherapy to treat anhedonia, compared to a Mindfulness-Based Cognitive Therapy (MBCT) comparison intervention (ClinicalTrials.gov Identifiers NCT02874534 and NCT04036136). Treatment completers (n = 72) experienced significant reductions in anhedonia (M = -8.94, SD = 5.66) on the Snaith-Hamilton Pleasure Scale (t(71) = 13.39, p < .0001), and significant reductions in perceived stress (M = -3.71, SD = 3.88) on the Perceived Stress Scale (t(71) = 8.11, p < .0001) following treatment. Across all treatment-seeking participants (n = 87), a longitudinal autoregressive cross-lagged model revealed significant paths showing that higher levels of perceived stress at treatment Week 1 predicted reductions in anhedonia at treatment Week 4; lower levels of perceived stress at Week 8 predicted reductions in anhedonia at Week 12. Anhedonia did not significantly predict perceived stress at any stage of treatment. This study showed specific timing and directional effects of perceived stress on anhedonia during psychotherapy treatment. Individuals with relatively high perceived stress at the start of treatment were more likely to report relatively lower anhedonia a few weeks into treatment. At mid-treatment, individuals with low perceived stress were more likely to report lower anhedonia towards the end of treatment. These results demonstrate that early treatment components reduce perceived stress, thus allowing for downstream changes in hedonic functioning during mid-late treatment. The findings presented here suggest it will be critically important for future clinical trials evaluating novel interventions for anhedonia to measure stress levels repeatedly, as an important mechanism of change. Development of a Novel Transdiagnostic Intervention for Anhedonia - R61 Phase. TRIAL URL: https://clinicaltrials.gov/ct2/show/NCT02874534. NCT02874534.
Abstract Summary: Scientists did a study to see if a new kind of therapy could help people who don't feel pleasure from things they used to enjoy, a problem called anhedonia. They also wanted to know if feeling less stressed out could make people feel more pleasure again. They had 72 people try two different therapies for 15 weeks. They found that both therapies helped people feel less stressed and more able to enjoy things. They also learned that if people felt less stressed at the beginning of therapy, they were more likely to start enjoying things a few weeks later. This study tells us that it's really important to check how stressed someone is when they're getting treatment for not feeling pleasure, because feeling less stressed can help them get better.

Kidney and Cardiovascular Effects of Canagliflozin According to Age and Sex: A Post Hoc Analysis of the CREDENCE Randomized Clinical Trial.
Am J Kidney Dis.
2023 Jul;
82(1):84-96.e1.
Abstract: It is unclear whether the effect of canagliflozin on adverse kidney and cardiovascular events in those with diabetic kidney disease varies by age and sex. We assessed the effects of canagliflozin among age group categories and between sexes in the Canagliflozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) study. Secondary analysis of a randomized controlled trial. Participants in the CREDENCE trial. Participants were randomly assigned to receive canagliflozin 100mg/d or placebo. Primary composite outcome of kidney failure, doubling of serum creatinine concentration, or death due to kidney or cardiovascular disease. Prespecified secondary and safety outcomes were also analyzed. Outcomes were evaluated by age at baseline (<60, 60-69, and≥70 years) and sex in the intention-to-treat population using Cox regression models. The mean age of the cohort was 63.0±9.2 years, and 34% were female. Older age and female sex were independently associated with a lower risk of the composite of adverse kidney outcomes. There was no evidence that the effect of canagliflozin on the primary outcome (a composite of kidney failure, a doubling of serum creatinine concentration, or death from kidney or cardiovascular causes) differed between age groups (HRs, 0.67 [95% CI, 0.52-0.87], 0.63 [0.48-0.82], and 0.89 [0.61-1.29] for ages<60, 60-69, and≥70 years, respectively; P=0.3for interaction) or sexes (HRs, 0.71 [95% CI, 0.54-0.95] and 0.69 [0.56-0.84] in women and men, respectively; P=0.8for interaction). No differences in safety outcomes by age group or sex were observed. This was a post hoc analysis with multiple comparisons. Canagliflozin consistently reduced the relative risk of kidney events in people with diabetic kidney disease in both sexes and across age subgroups. As a result of greater background risk, the absolute reduction in adverse kidney outcomes was greater in younger participants. This post hoc analysis of the CREDENCE trial was not funded. The CREDENCE study was sponsored by Janssen Research and Development and was conducted collaboratively by the sponsor, an academic-led steering committee, and an academic research organization, George Clinical. The original CREDENCE trial was registered at ClinicalTrials.gov with study number NCT02065791.
Abstract Summary: Scientists wanted to see if a medicine called canagliflozin helps adults with diabetes and kidney problems in the same way, no matter their age or if they are a boy or a girl. They looked at a big study where people took either canagliflozin or a pretend pill every day. They checked if the medicine stopped their kidneys from getting worse or if it kept them from dying because of kidney or heart problems. They found that the medicine worked well for everyone, both younger and older people, and for both boys and girls. It was especially good at helping younger people avoid kidney problems. This information is important because it shows that this medicine can help lots of different people with diabetes keep their kidneys healthy.

Abstract: To compare the efficacy of tai ji quan versus strength training to prevent falls after chemotherapy in older, postmenopaual women. We conducted a three-arm, single-blind, randomized controlled trial where older (50+ years), postmenopausal women cancer survivors participated in one of three supervised group exercise programs (tai ji quan, strength training, or stretching control) twice weekly for 6 months and were followed up 6 months after training stopped. The primary outcome was the incidence of falls. Secondary outcomes included fall-related injuries, leg strength (1 repetition maximum; kg), and balance (sensory organization [equilibrium score] and limits of stability [LOS; %] tests). Four hundred sixty-two women were enrolled (mean age, 62 ± 6.3 years). Retention was 93%, and adherence averaged 72.9%. In primary analysis, there was no difference in the incidence of falls between groups after 6 months of training, nor during 6-month follow-up. A post hoc analysis detected a significantly reduced incidence of fall-related injuries within the tai ji quan group over the first 6 months, dropping from 4.3 falls per 100 person-months (95% CI, 2.9 to 5.6) at baseline to 2.4 falls per person-months (95% CI, 1.2 to 3.5). No significant changes occurred during 6-month follow-up. Over the intervention period, leg strength significantly improved in the strength group and balance (LOS) improved in the tai ji quan group, compared with controls ( < .05). We found no significant reduction in falls for tai ji quan or strength training relative to stretching control in postmenopausal women treated with chemotherapy.
Abstract Summary: Scientists wanted to see if two types of exercise, tai chi or strength training, could help older women who survived cancer and went through menopause to not fall down as much after their chemotherapy treatment. They had these women do one of three exercises: tai chi, strength training, or just stretching, two times a week for six months. They checked on the women for another six months after the exercises stopped. They wanted to see how many times the women fell, if they got hurt from falling, how strong their legs were, and how well they could balance.
They found that after six months, the number of falls didn't really change no matter what exercise the women did. But, the women who did tai chi had fewer injuries from falls during the first six months. Also, the women who did strength training got stronger legs, and those who did tai chi got better at balancing compared to the women who just stretched.
In the end, the study showed that while tai chi and strength training didn't stop the women from falling, tai chi might help them get hurt less, and both tai chi and strength training can make them stronger and more balanced.

Associations of body size with all-cause and cause-specific mortality in healthy older adults.
Sci Rep.
2023 Mar 7;
13(1):3799.
Abstract: In the general population, body mass index (BMI) and waist circumference are recognized risk factors for several chronic diseases and all-cause mortality. However, whether these associations are the same for older adults is less clear. The association of baseline BMI and waist circumference with all-cause and cause-specific mortality was investigated in 18,209 Australian and US participants (mean age: 75.1 ± 4.5 years) from the ASPirin in Reducing Events in the Elderly (ASPREE) study, followed up for a median of 6.9 years (IQR: 5.7, 8.0). There were substantially different relationships observed in men and women. In men, the lowest risk of all-cause and cardiovascular mortality was observed with a BMI in the range 25.0-29.9 kg/m [HR: 0.85; 95% CI, 0.73-1.00] while the highest risk was in those who were underweight [HR: 1.82; 95% CI 1.30-2.55], leading to a clear U-shaped relationship. In women, all-cause mortality was highest in those with the lowest BMI leading to a J-shaped relationship (HR: 1.64; 95% CI 1.26-2.14). Waist circumference showed a weaker relationship with all-cause mortality in both men and women. There was little evidence of a relationship between either index of body size and subsequent cancer mortality in men or women, while non-cardiovascular non-cancer mortality was higher in underweight participants. For older men, being overweight was found to be associated with a lower risk of all-cause mortality, while among both men and women, a BMI in the underweight category was associated with a higher risk. Waist circumference alone had little association with all-cause or cause-specific mortality risk.Trial registration ASPREE https://ClinicalTrials.gov number NCT01038583.
Abstract Summary: Scientists wanted to find out if being heavier or having a bigger waist size affects the chances of getting sick or dying for older people, just like it does for others. They looked at over 18,000 older adults from Australia and the USA for about 7 years. They found that for older men, being a bit overweight was actually linked to a lower chance of dying from heart problems or other causes. But being too skinny was riskier for both men and women. Having a bigger waist didn't seem to make as much of a difference. This study helps us understand that for older people, being a little overweight might not be as bad as we thought, especially for men.

Antidepressant Augmentation versus Switch in Treatment-Resistant Geriatric Depression.
N Engl J Med.
2023 Mar 23;
388(12):1067-1079.
Abstract: The benefits and risks of augmenting or switching antidepressants in older adults with treatment-resistant depression have not been extensively studied. We conducted a two-step, open-label trial involving adults 60 years of age or older with treatment-resistant depression. In step 1, patients were randomly assigned in a 1:1:1 ratio to augmentation of existing antidepressant medication with aripiprazole, augmentation with bupropion, or a switch from existing antidepressant medication to bupropion. Patients who did not benefit from or were ineligible for step 1 were randomly assigned in step 2 in a 1:1 ratio to augmentation with lithium or a switch to nortriptyline. Each step lasted approximately 10 weeks. The primary outcome was the change from baseline in psychological well-being, assessed with the National Institutes of Health Toolbox Positive Affect and General Life Satisfaction subscales (population mean, 50; higher scores indicate greater well-being). A secondary outcome was remission of depression. In step 1, a total of 619 patients were enrolled; 211 were assigned to aripiprazole augmentation, 206 to bupropion augmentation, and 202 to a switch to bupropion. Well-being scores improved by 4.83 points, 4.33 points, and 2.04 points, respectively. The difference between the aripiprazole-augmentation group and the switch-to-bupropion group was 2.79 points (95% CI, 0.56 to 5.02; P = 0.014, with a prespecified threshold P value of 0.017); the between-group differences were not significant for aripiprazole augmentation versus bupropion augmentation or for bupropion augmentation versus a switch to bupropion. Remission occurred in 28.9% of patients in the aripiprazole-augmentation group, 28.2% in the bupropion-augmentation group, and 19.3% in the switch-to-bupropion group. The rate of falls was highest with bupropion augmentation. In step 2, a total of 248 patients were enrolled; 127 were assigned to lithium augmentation and 121 to a switch to nortriptyline. Well-being scores improved by 3.17 points and 2.18 points, respectively (difference, 0.99; 95% CI, -1.92 to 3.91). Remission occurred in 18.9% of patients in the lithium-augmentation group and 21.5% in the switch-to-nortriptyline group; rates of falling were similar in the two groups. In older adults with treatment-resistant depression, augmentation of existing antidepressants with aripiprazole improved well-being significantly more over 10 weeks than a switch to bupropion and was associated with a numerically higher incidence of remission. Among patients in whom augmentation or a switch to bupropion failed, changes in well-being and the occurrence of remission with lithium augmentation or a switch to nortriptyline were similar. (Funded by the Patient-Centered Outcomes Research Institute; OPTIMUM ClinicalTrials.gov number, NCT02960763.).
Abstract Summary: Doctors wanted to find out the best way to help older people who were still feeling sad even after taking medicine for depression. They did a study with two parts. In the first part, they gave some people an extra medicine called aripiprazole, some got an extra medicine called bupropion, and some stopped their old medicine and just took bupropion. They found that adding aripiprazole made people feel a bit happier than just switching to bupropion. In the second part, for people who didn't feel better after the first part, they tried adding lithium or switching to a medicine called nortriptyline. Both of these changes helped people feel a little happier, but there wasn't a big difference between the two. This study helps doctors know better ways to help older adults who have depression that's hard to treat.

Association of metformin, aspirin, and cancer incidence with mortality risk in adults with diabetes.
JNCI Cancer Spectr.
2023 Mar 1;
7(2):.
Abstract: Metformin and aspirin are commonly co-prescribed to people with diabetes. Metformin may prevent cancer, but in older people (over 70 years), aspirin has been found to increase cancer mortality. This study examined whether metformin reduces cancer mortality and incidence in older people with diabetes; it used randomization to 100 mg aspirin or placebo in the ASPirin in Reducing Events in the Elderly (ASPREE) trial to quantify aspirin's impact on metformin users. Analysis included community-dwelling ASPREE participants (aged ≥70 years, or ≥65 years for members of US minority populations) with diabetes. Diabetes was defined as a fasting blood glucose level greater than 125 mg/dL, self-report of diabetes, or antidiabetic medication use. Cox proportional hazards regression models were used to analyze the association of metformin and a metformin-aspirin interaction with cancer incidence and mortality, with adjustment for confounders. Of 2045 participants with diabetes at enrollment, 965 were concurrently using metformin. Metformin was associated with a reduced cancer incidence risk (adjusted hazard ratio [HR] = 0.68, 95% confidence interval [CI] = 0.51 to 0.90), but no conclusive benefit for cancer mortality (adjusted HR = 0.72, 95% CI = 0.43 to 1.19). Metformin users randomized to aspirin had greater risk of cancer mortality compared with placebo (HR = 2.53, 95% CI = 1.18 to 5.43), but no effect was seen for cancer incidence (HR = 1.11, 95% CI = 0.75 to 1.64). The possible effect modification of aspirin on cancer mortality, however, was not statistically significant (interaction P = .11). In community-dwelling older adults with diabetes, metformin use was associated with reduced cancer incidence. Increased cancer mortality risk in metformin users randomized to aspirin warrants further investigation. ClinicalTrials.gov ID NCT01038583.
Abstract Summary: Doctors often give people with diabetes two medicines called metformin and aspirin. Metformin might help prevent cancer, but aspirin could make cancer more deadly for older people. This study looked at older adults with diabetes to see if metformin helps them live longer without getting cancer. They also checked if taking aspirin changes anything.
The study included older people, some who were taking metformin, and some who were also taking aspirin or a fake pill (placebo). They found that those taking metformin got cancer less often. However, for those taking both metformin and aspirin, there was a higher chance of dying from cancer, but this finding needs more research to be sure.
This study is important because it suggests that metformin might help older people with diabetes avoid getting cancer, but combining it with aspirin could be risky. More studies are needed to understand this better.

Abstract: Recurrent gene dosage disorders impart substantial risk for psychopathology. Yet, understanding that risk is hampered by complex presentations that challenge classical diagnostic systems. Here, we present a suite of generalizable analytic approaches for parsing this clinical complexity, which we illustrate through application to XYY syndrome. We gathered high-dimensional measures of psychopathology in 64 XYY individuals and 60 XY controls, plus additional interviewer-based diagnostic data in the XYY group. We provide the first comprehensive diagnostic description of psychiatric morbidity in XYY syndrome and show how diagnostic morbidity relates to functioning, subthreshold symptoms, and ascertainment bias. We then map behavioral vulnerabilities and resilience across 67 behavioral dimensions before borrowing techniques from network science to resolve the mesoscale architecture of these dimensions and links to observable functional outcomes. Carriage of an extra Y-chromosome increases risk for diverse psychiatric diagnoses, with clinically impactful subthreshold symptomatology. Highest rates are seen for neurodevelopmental and affective disorders. A lower bound of < 25% of carriers are free of any diagnosis. Dimensional analysis of 67 scales details the profile of psychopathology in XYY, which survives control for ascertainment bias, specifies attentional and social domains as the most impacted, and refutes stigmatizing historical associations between XYY and violence. Network modeling compresses all measured symptom scales into 8 modules with dissociable links to cognitive ability, adaptive function, and caregiver strain. Hub modules offer efficient proxies for the full symptom network. This study parses the complex behavioral phenotype of XYY syndrome by applying new and generalizable analytic approaches for analysis of deep-phenotypic psychiatric data in neurogenetic disorders.
Abstract Summary: Scientists did a study to understand how having an extra Y chromosome (XYY syndrome) can affect mental health. They looked at 64 people with XYY and 60 people without it. They found that having XYY can lead to different mental health issues, especially problems with how the brain develops and mood disorders. Less than 25% of people with XYY don't have any mental health diagnosis. The study also found that attention and social skills are the most affected, but having XYY doesn't mean a person will be violent. They used special math to group symptoms into 8 categories, which helps understand how XYY affects thinking skills, daily life, and stress for caregivers. This research helps us know more about XYY and can be used to study other genetic conditions that affect mental health.

Abstract: BACKGROUNDMosaic and consensus HIV-1 immunogens provide two distinct approaches to elicit greater breadth of coverage against globally circulating HIV-1 and have shown improved immunologic breadth in nonhuman primate models.METHODSThis double-blind randomized trial enrolled 105 healthy HIV-uninfected adults who received 3 doses of either a trivalent global mosaic, a group M consensus (CON-S), or a natural clade B (Nat-B) gp160 env DNA vaccine followed by 2 doses of a heterologous modified vaccinia Ankara-vectored HIV-1 vaccine or placebo. We performed prespecified blinded immunogenicity analyses at day 70 and day 238 after the first immunization. T cell responses to vaccine antigens and 5 heterologous Env variants were fully mapped.RESULTSEnv-specific CD4+ T cell responses were induced in 71% of the mosaic vaccine recipients versus 48% of the CON-S recipients and 48% of the natural Env recipients. The mean number of T cell epitopes recognized was 2.5 (95% CI, 1.2-4.2) for mosaic recipients, 1.6 (95% CI, 0.82-2.6) for CON-S recipients, and 1.1 (95% CI, 0.62-1.71) for Nat-B recipients. Mean breadth was significantly greater in the mosaic group than in the Nat-B group using overall (P = 0.014), prime-matched (P = 0.002), heterologous (P = 0.046), and boost-matched (P = 0.009) measures. Overall T cell breadth was largely due to Env-specific CD4+ T cell responses.CONCLUSIONPriming with a mosaic antigen significantly increased the number of epitopes recognized by Env-specific T cells and enabled more, albeit still limited, cross-recognition of heterologous variants. Mosaic and consensus immunogens are promising approaches to address global diversity of HIV-1.TRIAL REGISTRATIONClinicalTrials.gov NCT02296541.FUNDINGUS NIH grants UM1 AI068614, UM1 AI068635, UM1 AI068618, UM1 AI069412, UL1 RR025758, P30 AI064518, UM1 AI100645, and UM1 AI144371, and Bill & Melinda Gates Foundation grant OPP52282.
Abstract Summary: Scientists did a study to see which of three different HIV vaccines worked best in people who don't have HIV. They gave 105 healthy adults three shots of one of the vaccines and then two more shots of another kind of vaccine or a pretend vaccine. They checked how well the vaccines worked on two different days. They found that the "mosaic" vaccine made the body's defense cells respond to more parts of the virus than the other two vaccines. This means the mosaic vaccine might be better at protecting against different kinds of HIV around the world. The study was paid for by the U.S. government and the Bill & Melinda Gates Foundation.

Abstract: After stroke, increases in contralesional primary motor cortex (M1) activity and excitability have been reported. In pre-clinical studies, M1 reorganization is related to the extent of ipsilesional M1 (M1) injury, but this has yet to be tested clinically. We tested the hypothesis that the extent of damage to the ipsilesional M1 and/or its corticospinal tract (CST) determines the magnitude of M1 reorganization and its relationship to affected hand function in humans recovering from stroke. Thirty-five participants with a single subacute ischemic stroke affecting M1 or CST and hand paresis underwent MRI scans of the brain to measure lesion volume and CST lesion load. Transcranial magnetic stimulation (TMS) of M1 was used to determine the presence of an electromyographic response (motor evoked potential (MEP+ and MEP-)). M1 reorganization was determined by TMS applied to M1 at increasing intensities. Hand function was quantified with the Jebsen Taylor Hand Function Test. The extent of M1 reorganization was related to greater lesion volume in the MEP- group, but not in the MEP+ group. Greater M1 reorganization was associated with more impaired hand function in MEP- but not MEP+ participants. Absence of an MEP (MEP-), larger lesion volumes and higher lesion loads in CST, particularly in CST fibers originating in M1 were associated with greater impairment of hand function. In the subacute post-stroke period, stroke volume and M1 output determine the extent of M1 reorganization and its relationship to affected hand function, consistent with pre-clinical evidence.ClinicalTrials.gov Identifier: NCT02544503.
Abstract Summary: Scientists did a study to see how the brain changes after a stroke and how these changes affect the use of a person's hand. They looked at 35 people who had a stroke that made it hard for them to move their hand. They used a special machine to take pictures of their brains and another machine to test the muscles in their hands. They found that when the stroke damaged a bigger part of the brain, the brain tried to reorganize itself more, but this didn't always help the hand get better. In fact, if the stroke was really big or if the part of the brain that sends signals to the hand was hurt a lot, the hand didn't work as well. This study helps doctors understand that the size of the stroke and where it happens in the brain can affect how much the hand can recover after a stroke.

Mixed Origins: HIV gp120-Specific Memory Develops from Pre-Existing Memory and Naive B Cells Following Vaccination in Humans.
AIDS Res Hum Retroviruses.
2023 Jul;
39(7):350-366.
Abstract: The most potent and broad HIV envelope (Env)-specific antibodies often when reverted to their inferred germline versions representing the naive B cell receptor, fail to bind Env, suggesting that the initial responding B cell population not only exclusively comprises a naive population, but also a pre-existing cross-reactive antigen-experienced B cell pool that expands following Env exposure. Previously we isolated gp120-reactive monoclonal antibodies (mAbs) from participants in HVTN 105, an HIV vaccine trial. Using deep sequencing, focused on immunoglobulin G (IgG), IgA, and IgM, VH-lineage tracking, we identified four of these mAb lineages in pre-immune peripheral blood. We also looked through the ∼7 month postvaccination bone marrow, and interestingly, several of these lineages that were found in prevaccination blood were still persistent in the postvaccination bone marrow, including the CD138+ long-lived plasma cell compartment. The majority of the pre-immune lineage members included IgM, however, IgG and IgA members were also prevalent and exhibited somatic hypermutation. These results suggest that vaccine-induced gp120-specific antibody lineages originate from both naive and cross-reactive memory B cells. ClinicalTrials.gov NCT02207920.
Abstract Summary: This study is about finding a better way to fight HIV, a dangerous virus. Scientists looked at how our body's defense system, specifically B cells, responds to HIV. They found that not only new B cells but also some experienced B cells that have fought other diseases can help fight HIV. They studied this by looking at blood samples from people who were part of an HIV vaccine trial. They found that some of the B cells that were there before the vaccine were still there after the vaccine, and they had changed to fight the virus better. This could help us make better vaccines in the future.

Abstract: Inclusion of self-reported and capacity-based measures may help to further elucidate the interactive link between how people think and move. To characterize the relationship between self-reported factors of physical function and pain with objective physical capacity measures. Cross-sectional study of 328 adults with chronic low back pain (CLBP). Spearman correlations assessed the relationship between pairs of measures. Multiple linear regression models assessed the association between self-reported measures of physical function and the grouping of physical capacity measures. Self-reported measures included Roland Morris Disability Questionnaire (RMDQ), PROMIS Physical Function, Pain Behavior, and Pain Interference; Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and Chronic Pain Acceptance Questionnaire (CPAQ). Capacity measures included walking speed and endurance, lower extremity functional strength, lumbopelvic range of motion, and trunk endurance. PROMIS Physical Function was directly and weakly correlated with walking speed (ρ = 0.26, 2-min walk) and inversely and weakly correlated with lower extremity strength (ρ = -0.29, 5x sit-to-stand). RMDQ was not correlated with any of the capacity-based measures. PROMIS Physical Function was inversely and moderately correlated with Pain Interference (ρ = -0.48) and Pain Behavior (ρ = -0.43), PCS (ρ = -0.36), and FABQ (ρ = -0.31). The RMDQ was strongly correlated with PROMIS Physical Function (ρ = -0.56), Pain Behavior (ρ = 0.51) and Pain Interference (ρ = 0.49); and moderately correlated with PCS (ρ = 0.37) and FABQ (ρ = 0.33). PROMIS Physical Function and RMDQ were not correlated with CPAQ. Lower scores on PROMIS Physical Function were weakly associated with lower measures of lower extremity strength (-0.30, 95% CI: -0.51 to -0.09, p = 0.005). Higher scores on RMDQ were also weakly associated with lower measures of lower extremity strength (0.26, 95% CI: 0.11 to 0.41, p = 0.001). A strong association emerged between self-reported limitations in physical function, pain behavior, and pain interference. A weak association emerged between self-reported physical function and lower extremity strength.
Abstract Summary: Scientists did a study to understand the connection between what people with chronic low back pain think about their ability to move and how well they actually can move. They asked 328 adults with this kind of pain to fill out questionnaires about their pain and how it affects their daily life. They also tested how fast the people could walk, how strong their legs were, how well they could move their lower back and hips, and how long their back muscles could work without getting tired.
They found that what people said about their physical abilities was a little bit related to their walking speed and leg strength. But there was a stronger link between what they said about their abilities and how much their pain changed the way they live their lives. People who felt more limited by their pain also seemed to have less leg strength.
This study is important because it shows that what people say about their pain and abilities can give us clues about their actual physical strength. This can help doctors and therapists understand and treat people with chronic low back pain better.

Sex hormones, SHBG and cognitive performance among older Australian women: an observational study.
Climacteric.
2023 Apr;
26(2):121-128.
Abstract: This study aims to explore the associations between sex hormones and cognitive performance in older women. Associations between sex hormones, sex hormone binding globulin (SHBG) and cognitive performance were examined in women aged at least 70 years, without dementia and not using medications that influence sex hormones. Linear and generalized linear regression models included age, body mass index, education, smoking, alcohol, living circumstances, diabetes, hypertension, depression and impaired renal function. The included 5511 women had a median (interquartile range) age of 73.9 (71.6-77.6) years. No associations were found for estrone, estradiol, testosterone or dehydroepiandrosterone and cognitive performance. SHBG concentrations above quartile 1 (Q1) were significantly inversely associated with processing speed (Q2, = -0.94, 95% confidence interval [CI] - 1.64 to -0.24, = 0.009; Q3, = -0.82, 95% CI -1.53 to -0.10, = 0.025; and Q4, = -0.95, 95% CI -1.70 to -0.20, = 0.013). Sex hormones were not associated with cognitive performance. The finding that low SHBG is associated with better processing speed warrants further investigation. The null findings for the sex hormones establish a firm baseline to confidently explore the association between sex hormones and longitudinal cognitive performance in this population. International Standard Randomized Controlled Trial Number Register (ISRCTN83772183) and ClinicalTrials.gov (NCT01038583).
Abstract Summary: Scientists did a study to see if there's a link between certain hormones and how well older women can think and remember things. They looked at a bunch of women who were 70 or older, who didn't have memory problems and weren't taking hormone-related medicine. They checked things like age, weight, education, smoking, drinking, living situation, diabetes, high blood pressure, sadness, and kidney health. They had 5,511 women in the study.
They found that most hormones didn't affect the women's thinking or memory. But they did notice that women with lower levels of a hormone called SHBG were a bit quicker at processing information. This was interesting, so they think it should be looked into more. The study helps us know that these hormones don't usually change how well older women think, which is good to know for future research.

27(1):1-9.
Abstract: To examine the association between metabolic syndrome (MetS) and frailty, and determine whether co-existent MetS and frailty affect disability-free survival (DFS), assessed through a composite of death, dementia or physical disability. Longitudinal study. Community-dwelling older adults from Australia and the United States (n=18,264) from "ASPirin in Reducing Events in the Elderly" (ASPREE) study. MetS was defined according to American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines (2018). A modified Fried phenotype and a deficit accumulation Frailty Index (FI) were used to assess frailty. Association between MetS and frailty was examined using multinomial logistic regression. Cox regression was used to analyze the association between MetS, frailty and DFS over a median follow-up of 4.7 years. Among 18,264 participants, 49.9% met the criteria for MetS at baseline. Participants with Mets were more likely to be pre-frail [Relative Risk Ratio (RRR): 1.22; 95%Confidence Interval (CI): 1.14, 1.30)] or frail (RRR: 1.66; 95%CI: 1.32, 2.08) than those without MetS. MetS alone did not shorten DFS while pre-frailty or frailty alone did [Hazard Ratio (HR): 1.68; 95%CI: 1.45, 1.94; HR: 2.65; 95%CI:1.92, 3.66, respectively]. Co-existent MetS with pre-frailty/frailty did not change the risk of shortened DFS. MetS was associated with pre-frailty or frailty in community-dwelling older individuals. Pre-frailty or frailty increased the risk of reduced DFS but presence of MetS did not change this risk. Assessment of frailty may be more important than MetS in predicting survival free of dementia or physical disability.
Abstract Summary: Scientists did a study to see if having a group of health problems called metabolic syndrome (MetS) makes older people more likely to become weak and less able to take care of themselves without getting sick, losing their memory, or dying. They looked at over 18,000 older adults from Australia and the USA. They found that people with MetS were more likely to start getting weak. However, just having MetS didn't make it more likely for someone to have problems with their memory or to have trouble moving around. But if someone was already getting weak, having MetS didn't make things worse. This study tells us that checking if an older person is getting weak might be more helpful than just looking for MetS to keep them healthy and able to do things on their own.

Sex and prior exposure jointly shape innate immune responses to a live herpesvirus vaccine.

Abstract: Both sex and prior exposure to pathogens are known to influence responses to immune challenges, but their combined effects are not well established in humans, particularly in early innate responses critical for shaping subsequent outcomes. We employed systems immunology approaches to study responses to a replication-defective, herpes simplex virus (HSV) 2 vaccine in men and women either naive or previously exposed to HSV. Blood transcriptomic and cell population profiling showed substantial changes on day 1 after vaccination, but the responses depended on sex and whether the vaccinee was naive or previously exposed to HSV. The magnitude of early transcriptional responses was greatest in HSV naive women where type I interferon (IFN) signatures were prominent and associated negatively with vaccine-induced neutralizing antibody titers, suggesting that a strong early antiviral response reduced the uptake of this replication-defective virus vaccine. While HSV seronegative vaccine recipients had upregulation of gene sets in type I IFN (IFN-α/β) responses, HSV2 seropositive vaccine recipients tended to have responses focused more on type II IFN (IFN-γ) genes. These results together show that prior exposure and sex interact to shape early innate responses that then impact subsequent adaptive immune phenotypes. Intramural Research Program of the NIH, the National Institute of Allergy and Infectious Diseases, and other institutes supporting the Trans-NIH Center for Human Immunology, Autoimmunity, and Inflammation. The vaccine trial was supported through a clinical trial agreement between the National Institute of Allergy and Infectious Diseases and Sanofi Pasteur. Clinical trial number: NCT01915212.
Abstract Summary: Scientists wanted to understand how gender and previous exposure to germs affect the body's response to a vaccine for a virus called HSV. They studied the blood of men and women who either had or hadn't been exposed to HSV before. They found that the body's initial response to the vaccine was different depending on gender and previous exposure. Women who hadn't been exposed to HSV before had the strongest initial response, which seemed to reduce the effectiveness of the vaccine. This study shows that gender and previous exposure to germs can affect how our bodies respond to vaccines. This could help us make better vaccines in the future.

A Cross-Species Neuroimaging Study of Sex Chromosome Dosage Effects on Human and Mouse Brain Anatomy.
J Neurosci.
2023 Feb 22;
43(8):1321-1333.
Abstract: All eutherian mammals show chromosomal sex determination with contrasting sex chromosome dosages (SCDs) between males (XY) and females (XX). Studies in transgenic mice and humans with sex chromosome trisomy (SCT) have revealed direct SCD effects on regional mammalian brain anatomy, but we lack a formal test for cross-species conservation of these effects. Here, we develop a harmonized framework for comparative structural neuroimaging and apply this to systematically profile SCD effects on regional brain anatomy in both humans and mice by contrasting groups with SCT (XXY and XYY) versus XY controls. Total brain size was substantially altered by SCT in humans (significantly decreased by XXY and increased by XYY), but not in mice. Robust and spatially convergent effects of XXY and XYY on regional brain volume were observed in humans, but not mice, when controlling for global volume differences. However, mice do show subtle effects of XXY and XYY on regional volume, although there is not a general spatial convergence in these effects within mice or between species. Notwithstanding this general lack of conservation in SCT effects, we detect several brain regions that show overlapping effects of XXY and XYY both within and between species (cerebellar, parietal, and orbitofrontal cortex), thereby nominating high priority targets for future translational dissection of SCD effects on the mammalian brain. Our study introduces a generalizable framework for comparative neuroimaging in humans and mice and applies this to achieve a cross-species comparison of SCD effects on the mammalian brain through the lens of SCT. Sex chromosome dosage (SCD) affects neuroanatomy and risk for psychopathology in humans. Performing mechanistic studies in the human brain is challenging but possible in mouse models. Here, we develop a framework for cross-species neuroimaging analysis and use this to show that an added X- or Y-chromosome significantly alters human brain anatomy but has muted effects in the mouse brain. However, we do find evidence for conserved cross-species impact of an added chromosome in the fronto-parietal cortices and cerebellum, which point to regions for future mechanistic dissection of sex chromosome dosage effects on brain development.
Abstract Summary: Scientists wanted to see if having an extra sex chromosome affects the brain the same way in people and mice. They compared brain images of humans and mice with an extra X or Y chromosome to those with the usual number. They found that in people, an extra chromosome made the brain size bigger or smaller and changed certain parts of the brain. In mice, the changes were smaller and not the same across different mice. But they did find some brain areas in both humans and mice that were affected by the extra chromosome. This study helps us understand where to look in the brain to learn more about how extra sex chromosomes can change brain development.

Returning integrated genomic risk and clinical recommendations: The eMERGE study.
Genet Med.
2023 Apr;
25(4):100006.
Abstract: Assessing the risk of common, complex diseases requires consideration of clinical risk factors as well as monogenic and polygenic risks, which in turn may be reflected in family history. Returning risks to individuals and providers may influence preventive care or use of prophylactic therapies for those individuals at high genetic risk. To enable integrated genetic risk assessment, the eMERGE (electronic MEdical Records and GEnomics) network is enrolling 25,000 diverse individuals in a prospective cohort study across 10 sites. The network developed methods to return cross-ancestry polygenic risk scores, monogenic risks, family history, and clinical risk assessments via a genome-informed risk assessment (GIRA) report and will assess uptake of care recommendations after return of results. GIRAs include summary care recommendations for 11 conditions, education pages, and clinical laboratory reports. The return of high-risk GIRA to individuals and providers includes guidelines for care and lifestyle recommendations. Assembling the GIRA required infrastructure and workflows for ingesting and presenting content from multiple sources. Recruitment began in February 2022. Return of a novel report for communicating monogenic, polygenic, and family history-based risk factors will inform the benefits of integrated genetic risk assessment for routine health care.
Abstract Summary: Doctors want to know if understanding a person's family health history and their own unique genes can help prevent diseases. They are studying 25,000 people from different backgrounds to see if sharing this information with patients and doctors helps them make better health choices. They made special reports that include a person's gene information, family health history, and tips for staying healthy. They are checking if people follow these health tips after getting their reports. This study started in February 2022 and might show that knowing about your genes and family health can help keep you healthy.

Abstract: Frailty is a common geriatric syndrome that adversely impacts health outcomes. This study examined correlates of physical frailty in healthy community-dwelling older adults and studied the effect of frailty on disability-free survival (DFS), defined as survival free of independence-limiting physical disability or dementia. This is a post hoc analysis of 19,114 community-dwelling older adults (median age: 74.0 years, interquartile range or IQR: 6.1 years) from Australia and the USA enrolled in the "ASPirin in Reducing Events in the Elderly (ASPREE)" clinical trial. Frailty was assessed using a modified Fried phenotype and a deficit accumulation frailty index (FI) utilizing a ratio score derived from 66 items. Multinomial logistic regression was used to examine the correlates of frailty and Cox regression to analyze the association between frailty and DFS (and its components). At study enrollment, 39.0% were prefrail, and 2.2% of participants were frail, according to Fried phenotype. Older age, higher waist circumference, lower education, ethnoracial origin, current smoking, depression, and polypharmacy were associated with prefrailty and frailty according to Fried phenotype and FI. Fried phenotype defined prefrailty and frailty predicted reduced DFS (prefrail: HR: 1.67; 95% CI: 1.50-1.86 and frail: HR: 2.80; 95% CI: 2.27-3.46), affecting each component of DFS including dementia, physical disability, and mortality. Effect sizes were larger, according to FI. Our study showed that prefrailty is common in community-dwelling older adults initially free of cardiovascular disease, dementia, or independence-limiting physical disability. Prefrailty and frailty significantly reduced disability-free survival. Addressing modifiable correlates, like depression and polypharmacy, might reduce the adverse impact of frailty on dementia-free and physical disability-free survival.
Abstract Summary: Scientists did a study to learn about frailty, which is when older people get weak and it can lead to health problems. They looked at 19,114 older adults who lived on their own in Australia and the USA. They wanted to see how frailty affected the chances of living without getting a disability or dementia. They found that being a little frail was common, and being very frail was less common. Older people, those with bigger waists, less education, certain ethnic backgrounds, smokers, people feeling sad, and those taking many medicines were more likely to be frail. Frail people had a higher chance of getting a disability, dementia, or dying earlier. The study suggests that helping older adults with these problems might let them live longer without disabilities or dementia.

149(2):141-149.
Abstract: The number of olfactory dysfunction cases has increased dramatically because of the COVID-19 pandemic. Identifying therapies that aid and accelerate recovery is essential. To determine the efficacy of bimodal visual-olfactory training and patient-preferred scents vs unimodal olfactory training and physician-assigned scents in COVID-19 olfactory loss. This was a randomized, single-blinded trial with a 2-by-2 factorial design (bimodal, patient preferred; unimodal, physician assigned; bimodal, physician assigned; unimodal, patient preferred) and an independent control group. Enrollment occurred from February 1 to May 27, 2021. Participants were adults 18 to 71 years old with current olfactory loss defined as University of Pennsylvania Smell Identification Test (UPSIT) score less than 34 for men and less than 35 for women and duration of 3 months or longer. Olfactory loss was initially diagnosed within 2 weeks of COVID-19 infection. Participants sniffed 4 essential oils for 15 seconds with a 30-second rest in between odors for 3 months. Participants in the physician-assigned odor arms trained with rose, lemon, eucalyptus, and clove. Participants randomized to the patient-preferred arms chose 4 of 24 available scents. If assigned to the bimodal arm, participants were shown digital images of the essential oil they were smelling. The primary end point was postintervention change in UPSIT score from baseline; measures used were the UPSIT (validated, objective psychometric test of olfaction), Clinical Global Impressions Impression-Improvement (CGI-I; self-report improvement scale), and Olfactory Dysfunction Outcomes Rating (ODOR; olfaction-related quality-of-life questionnaire). Among the 275 enrolled participants, the mean (SD) age was 41 (12) years, and 236 (86%) were female. The change in UPSIT scores preintervention to postintervention was similar between the study arms. The marginal mean difference for change in UPSIT scores preintervention to postintervention between participants randomized to patient-preferred vs physician-assigned olfactory training was 0.73 (95% CI, -1.10 to 2.56), and between participants randomized to bimodal vs unimodal olfactory training was 1.10 (95% CI, -2.92 to 0.74). Five (24%) participants in the control arm had clinically important improvement on UPSIT compared with 18 (53%) in the bimodal, patient-preferred arm for a difference of 29% (95% CI, 4%-54%). Four (19%) participants in the control group self-reported improvement on CGI-I compared with 12 (35%) in the bimodal, patient-preferred arm for a difference of 16% (95% CI, -7% to 39%). The mean change in ODOR score preintervention to postintervention was 11.6 points (95% CI, 9.2-13.9), which was not deemed clinically important nor significantly different between arms. Based on the change in UPSIT scores, this randomized clinical trial did not show any difference between intervention arms, but when exploring within-patient change in UPSIT as well as self-reported impression of improvement, active interventions were associated with larger improvement than controls with a potential advantage of bimodal intervention. While not definitive, these results suggest that patients with COVID-19 olfactory loss may benefit from bimodal visual-olfactory training with patient-preferred scents. ClinicalTrials.gov Identifier: NCT04710394.
Abstract Summary: Scientists wanted to find out if certain smell training could help people who lost their sense of smell because of COVID-19. They had some people smell different oils and look at pictures of what they were smelling, while others just smelled the oils. Some got to pick their favorite smells, and others used scents chosen by doctors. They tested 275 adults to see if their smell got better after three months. They found that everyone got a little better, but those who used their favorite smells and looked at pictures improved the most. This study suggests that using pictures and favorite smells might help people who can't smell well after having COVID-19.

Randomized controlled trial of computerized approach/avoidance training in social anxiety disorder: Neural and symptom outcomes.
J Affect Disord.
2023 Mar 1;
324:36-45.
Abstract: Social anxiety is associated with diminished automatic approach toward positive social cues that may limit the ability to connect with others. This diminished approach bias may be a modifiable treatment target. We evaluated the effects of an approach avoidance training procedure on positive emotions, social relationship outcomes, clinical symptoms, and neural indices of social approach and reward processing. Forty-five individuals with social anxiety disorder were randomized (parallel 1:1 randomization) to complete computerized Approach Positive training (n = 21) or Balanced training(n = 24). Sessions included a standardized social interaction task. Participants were blind to training group. Participants completed clinical outcome measures and functional magnetic resonance imaging at baseline and post intervention with an MRI-compatible AAT and the social incentive delay task (SID). Both groups displayed significant improvements of similar magnitude on the primary outcome of social connectedness (between group post-treatment d = -0.21) but not positive affect (d = -0.09), from before to after treatment, persisting through follow-up. Groups demonstrated significant improvements on additional outcomes including anxiety, depression, and anhedonia symptoms. Participants in Approach Positive AAT demonstrated increased activation in the thalamus and medial prefrontal cortex during social versus neutral- approach relative to Balanced AAT during the fMRI AAT. Participants in Balanced AAT showed increased activation in regions within an a priori-defined striatum region of interest mask during anticipation of social reward (vs. baseline) in the SID relative to Approach Positive AAT. At a neural processing level AAT may influence the valuation and motivations associated with positive social cues regulated by the mPFC and thalamus. NCT02136212, NIMH R00MH090243.
Abstract Summary: This study looked at how a special type of training could help people with social anxiety, a condition that makes it hard for them to connect with others. The researchers had 45 people with social anxiety do computer exercises that either focused on positive social interactions or a mix of different types. They also did brain scans before and after the training. The results showed that both types of training helped improve social connections and reduced symptoms like anxiety and depression. The brain scans also showed changes in areas related to social interactions and rewards. This suggests that this type of training could be a helpful tool for people with social anxiety.

Abstract: There is currently no licensed vaccine for respiratory syncytial virus (RSV). Here, we assess the effect of RSV fusion protein (F) conformation on B cell responses in a post hoc comparison of samples from the DS-Cav1 [prefusion (pre-F)] and MEDI7510 [postfusion (post-F)] vaccine clinical trials. We compared the magnitude and quality of the serological and B cell responses across time points and vaccines. We measured RSV A and B neutralization, F-binding immunoglobulin G titers, and competition assays at week 0 (before vaccination) and week 4 (after vaccination) to evaluate antibody specificity and potency. To compare B cell specificity and activation, we used pre-F and post-F probes in tandem with a 17-color immunophenotyping flow cytometry panel at week 0 (before vaccination) and week 1 (after vaccination). Our data demonstrate that both DS-Cav1 and MEDI7510 vaccination robustly elicit F-specific antibodies and B cells, but DS-Cav1 elicited antibodies that more potently neutralized both RSV A and B. The superior potency was mediated by antibodies that bind antigenic sites on the apex of pre-F that are not present on post-F. In the memory (CD27) B cell compartment, vaccination with DS-Cav1 or MEDI7510 elicited B cells with different epitope specificities. B cells preferentially binding the pre-F probe were activated in DS-Cav1-vaccinated participants but not in MEDI7510-vaccinated participants. Our findings emphasize the importance of using pre-F as an immunogen in humans because of its deterministic role in eliciting highly potent neutralizing antibodies and memory B cells.
Abstract Summary: Scientists are trying to make a vaccine for a lung virus called RSV, but there isn't one yet. They did a study to see how two different RSV vaccines worked. They looked at people's blood before and after getting the vaccines to see what kind of fighters (antibodies and B cells) their bodies made. They found that both vaccines made fighters, but the DS-Cav1 vaccine made stronger ones that were better at stopping the virus. This vaccine worked by targeting a special part of the virus that the other vaccine didn't. The study shows that it's important to use the right part of the virus to make a really good vaccine that can help our bodies remember and fight off the virus better.

A Text-Based Smoking Cessation Intervention for Sexual and Gender Minority Groups: Protocol for a Feasibility Trial.
JMIR Res Protoc.
2022 Dec 9;
11(12):e42553.
Abstract: Smoking among sexual and gender minority (SGM) groups, which include lesbian, gay, bisexual, transgender, and queer individuals, has been reported to be highly prevalent. This is attributed to several factors, including minority-specific stress and targeted tobacco marketing. Therefore, this population is at an increased risk for tobacco-related diseases. SMS text messaging programs have been found to be effective for smoking cessation and appeal to traditionally hard-to-reach populations over other interventions. It has also been suggested that targeted and tailored interventions could be more effective among SGM smokers because they can be designed to assure a safe, validating health care environment that enhances receptivity to cessation. The aim of this study is to develop SmokefreeSGM, a text-based smoking cessation program tailored to and tested among SGM smokers. The study consists of three phases, culminating in a feasibility trial. In Phase 1, our research team will collaborate with a Community Advisory Board to develop and pretest the design of SmokefreeSGM. In Phase 2, the tailored text messaging program will be beta tested among 16 SGM smokers. Our research team will use a mixed-methods approach to collect and analyze data from participants who will inform the refinement of SmokefreeSGM. In Phase 3, a feasibility trial will be conducted among 80 SGM smokers either enrolled in SmokefreeSGM or SmokefreeTXT, the original text-based program developed by the National Cancer Institute for the general population. Our research team will examine recruitment, retention, and smoking abstinence rates at 1-, 3-, and 6-month follow-up. Additionally, a qualitative interview will be conducted among 32 participants to evaluate the feasibility and acceptability of the programs (SmokefreeSGM and SmokefreeTXT). This study received approval from The University of Texas Health Science Center at Houston Committee for the Protection of Human Subjects to begin research on August 21, 2020. Recruitment for the beta testing of SmokefreeSGM (Phase 2) began in January 2022. We estimate that the feasibility trial (Phase 3) will begin in September 2022 and that results will be available in December 2023. Findings from this research effort will help reduce tobacco-related health disparities among SGM smokers by determining the feasibility and acceptability of SmokefreeSGM, an SGM-tailored smoking cessation intervention. ClinicalTrials.gov NCT05029362; https://clinicaltrials.gov/ct2/show/NCT05029362. DERR1-10.2196/42553.
Abstract Summary: Scientists are studying a new way to help people who are lesbian, gay, bisexual, transgender, and queer (LGBTQ) quit smoking. They know that LGBTQ people smoke a lot, partly because of stress and ads that make smoking look cool. They're making a special program called SmokefreeSGM that sends helpful texts to encourage LGBTQ people to stop smoking. They will test this program in three steps. First, they'll work with a group of advisors to make the texts. Then, they'll try it with a small group of 16 people to see how it works and make it better. Lastly, they'll see if it works well with 80 people, comparing it to a general text program. They'll talk to some of these people to learn more about what they think of the programs. The study started in 2020, and they began testing the texts in 2022. They hope to share the results by the end of 2023. If it works, this program could help LGBTQ people be healthier by quitting smoking.

Influences of resting-state intrinsic functional brain connectivity on the antidepressant treatment response in late-life depression.
Psychol Med.
2023 Oct;
53(13):6261-6270.
Abstract: Late-life depression (LLD) is characterized by differences in resting state functional connectivity within and between intrinsic functional networks. This study examined whether clinical improvement to antidepressant medications is associated with pre-randomization functional connectivity in intrinsic brain networks. Participants were 95 elders aged 60 years or older with major depressive disorder. After clinical assessments and baseline MRI, participants were randomized to escitalopram or placebo with a two-to-one allocation for 8 weeks. Non-remitting participants subsequently entered an 8-week trial of open-label bupropion. The main clinical outcome was depression severity measured by MADRS. Resting state functional connectivity was measured between key seeds in the default mode (DMN), cognitive control, and limbic networks. In primary analyses of blinded data, lower post-treatment MADRS score was associated with higher resting connectivity between: (a) posterior cingulate cortex (PCC) and left medial prefrontal cortex; (b) PCC and subgenual anterior cingulate cortex (ACC); (c) right medial PFC and subgenual ACC; (d) right orbitofrontal cortex and left hippocampus. Lower post-treatment MADRS was further associated with lower connectivity between: (e) the right orbitofrontal cortex and left amygdala; and (f) left dorsolateral PFC and left dorsal ACC. Secondary analyses associated mood improvement on escitalopram with anterior DMN hub connectivity. Exploratory analyses of the bupropion open-label trial associated improvement with subgenual ACC, frontal, and amygdala connectivity. Response to antidepressants in LLD is related to connectivity in the DMN, cognitive control and limbic networks. Future work should focus on clinical markers of network connectivity informing prognosis. ClinicalTrials.gov NCT02332291.
Abstract Summary: Doctors wanted to see if brain connections could tell us if older people with sadness would feel better after taking medicine. They looked at 95 older people with deep sadness and checked their brains with a special scan. These people then took a medicine called escitalopram or a pretend pill for 8 weeks. If they still felt sad, they tried another medicine called bupropion for 8 more weeks. The doctors found that certain brain connections could predict who would feel less sad after the treatment. This is important because it might help doctors know which medicine will make someone feel better by looking at their brain scans.

Association of fall rate and functional status by APOE genotype in cancer survivors after exercise intervention.

Abstract: Cancer treatment survivors often report impaired functioning and increased falls. Not all survivors experience the same symptom burden, suggesting individual susceptibilities. genotype is a potential genetic risk factor for cancer treatment related side effects. Lifestyle factors such as physical activity can mitigate the effect of genotype on measures of clinical interest in individuals without a history of cancer. We tested the hypothesis that genotype influences cancer treatment related side effects and symptoms as well as response to exercise intervention. Data from a subsample of a study of fall prevention exercise in post-treatment female cancer survivors aged 50-75 years old (https://clinicaltrials.gov NCT01635413) were used to conduct a secondary data analysis. ApoE genotype was determined by serum sampling. Physical functioning, frequency of falls, and symptom burden were assessed using survey instruments. Data from 126 female cancer survivors a median of 49 months out from cancer diagnosis were analyzed. ApoE4 carriers trended toward a higher fall rate at baseline ( = 0.059), but after exercise intervention had a fall rate lower than E4 non-carriers both immediately after structured intervention ( = 0.013) and after 6 months of follow up ( = 0.002). E2 carriers did not show improved measures of depressive symptoms and self-report disability after exercise intervention. E3 homozygotes showed increased self report physical activity after the 6 month exercise intervention, but E4 and E2 carriers did not. genotype may modulate cancer treatment related side effects and symptoms and response to exercise intervention.
Abstract Summary: Scientists did a study to see if a certain gene, called ApoE, affects how people who had cancer treatment feel and how often they fall down. They also wanted to know if exercising could help these people feel better and fall less, no matter what type of ApoE gene they have. They looked at 126 women who had finished cancer treatment about 4 years ago. They found that people with one type of the ApoE gene, called E4, fell down more at first, but after they started exercising, they fell down less than people without the E4 type. People with another type, E2, didn't feel less sad or less disabled after exercising. People with the E3 type did more physical activity after exercising for 6 months, but those with E4 and E2 didn't change much. This study shows that the ApoE gene might change how exercise helps people who had cancer treatment.

Abstract: Generalized anxiety disorder (GAD) is a significant yet modifiable risk factor for worse cardiovascular disease (CVD) outcomes. The treatment of GAD in an accessible manner represents an unmet need in CVD, given that patients with CVD experience numerous barriers to in-person treatment engagement. This paper presents the rationale and design for an investigation of a strategy to enhance care for patients with CVD by introducing a scalable, affordable, and system-friendly digital intervention that targets a prominent modifiable risk factor (generalized anxiety and associated worry) for negative health behaviors in CVD. In the context of a randomized clinical trial design, we describe an experimental medicine approach for evaluating the degree to which a digital cognitive behavior therapy (dCBT), relative to a waitlist control group, engages anxiety and worry outcomes in a sample of 90 adults who have experienced an acute CVD event and who have comorbid GAD symptoms. We also investigate the degree to which dCBT leads to greater changes in GAD symptoms compared to the control condition and whether reductions in these symptoms are associated with corresponding reductions in cardiac anxiety and cardiac health behaviors (including smoking, physical activity, heart-healthy diet, and medication adherence). We propose that by targeting GAD symptoms in CVD in a way that does not tax ongoing medical care provision, we have the potential to improve the uptake of effective care and address both GAD and associated health behaviors.
Abstract Summary: Doctors found that people with a lot of worry and anxiety, especially about their health, might have more heart problems. They think helping these people worry less could make their hearts healthier. So, they're trying out a new way to help using computers and the internet, which is easier for people to use than going to the doctor's office. They're testing this idea with 90 adults who have heart problems and also worry a lot. These adults will try a special computer program that teaches them how to worry less. The doctors will see if the people who use the program start to worry less and if that helps them do better things for their hearts, like eating healthy, exercising, and taking their medicine. If it works, this could be a new way to help lots of people with heart problems and anxiety feel better without making their regular doctor visits harder.

Abstract: Clear health disparities have emerged in the rates of COVID-19 exposure, hospitalization, and death among Black, Hispanic, and American Indian (BHAI) individuals, relative to non-Hispanic White (NHW) individuals. BHAI populations have been disproportionately affected by lower behavioral health access and heightened negative mental health outcomes during the pandemic. This project directly addresses health disparities in access to behavioral health care during the COVID-19 pandemic among BHAI populations via an adaptation of the established, initially validated, low-cost, mobile app Easing Anxiety Sensitivity for Everyone (EASE) among individuals with symptoms of elevated anxiety or depression or both. The EASE trial is a 2-arm, prospective, randomized, blinded-assessor study with intention-to-treat analysis. Participants (N=800; n=200, 25%, Black; n=200, 25%, Hispanic; n=200, 25%, American Indian; and n=200, 25%, NHW) are randomized to receive either EASE or an active comparison condition for anxiety and depression. Participants compete an online prescreener, an enrollment call to provide informed consent, a baseline survey, a 6-month intervention period, and 3- and 6-month postbaseline assessments. Select participants also complete a 3- and 6-month postbaseline qualitative interview via phone or an online platform (eg, Zoom). Participants complete 2 scheduled daily ecological momentary assessments (EMAs) during the 6-month study period. These twice-daily EMAs guide a just-in-time approach to immediate, personalized behavioral health care. Outcomes include reductions in anxiety and depressive symptoms and functional impairment at 3 and 6 months postrandomization. We also will examine putative mechanisms (eg, anxiety sensitivity [AS] and COVID-19-specific stress and fear) of the intervention effects. Further, as treatment effects may differ across sociocultural factors, perceived discrimination, social support, and socioeconomic status (SES) will be evaluated as potential moderators of treatment effects on the primary outcomes. Process evaluation using data collected during the study, as well as individual interviews with participants, will complement quantitative data. Data from this efficacy trial will determine whether EASE successfully improves symptoms of anxiety and depression and whether these improvements outperform an active comparison control app. If successful, findings from this study have the potential to decrease anxiety and depression symptoms among vulnerable populations determined to be most at risk of exacerbated, long-lasting negative health sequelae. Data from this study may be used to support an implementation and dissemination trial of EASE within real-world behavioral health and social service settings. ClinicalTrials.gov NCT05074693; https://clinicaltrials.gov/ct2/show/NCT05074693. DERR1-10.2196/40713.
Abstract Summary: Scientists are studying how a mobile app called EASE can help people from Black, Hispanic, and American Indian communities, as well as non-Hispanic White people, who are feeling very anxious or sad because of COVID-19. They noticed that these communities don't always have the same chances to get help for mental health problems. In the study, 800 people will use either the EASE app or another app to see which one is better at making them feel less anxious and sad. They will answer questions and talk to researchers over 6 months to see if the app helps. If the EASE app works well, it could be used to help lots of people feel better during tough times like the pandemic.

Effects of Critical Distance and Reverberation on Listening Effort in Adults.

2022 Dec 12;
65(12):4837-4851.
Abstract: Mixed historical data on how listening effort is affected by reverberation and listener-to-speaker distance challenge existing models of listening effort. This study investigated the effects of reverberation and listener-to-speaker distance on behavioral and subjective measures of listening effort: (a) when listening at a fixed signal-to-noise ratio (SNR) and (b) at SNRs that were manipulated so that word recognition would be comparable across different reverberation times and listening distances. It was expected that increased reverberation would increase listening effort but only when listening outside critical distance. Nineteen adults (21-40 years) with no hearing loss completed a dual-task paradigm. The primary task was word recognition and the secondary task was timed word categorization; response times indexed behavioral listening effort. Additionally, participants provided subjective ratings in each condition. Testing was completed at two reverberation levels (moderate and high, RT = 469 and 1,223 ms, respectively) and at two listener-to-speaker distances (inside and outside critical distance for the test room, 1.25 and 4 m, respectively). Increased reverberation and listening distances worsened word recognition performance and both behavioral and subjective listening effort. The effect of reverberation was exacerbated when listeners were outside critical distance. Subjective experience of listening effort persisted even when word recognition was comparable across conditions. Longer reverberation times or listening outside the room's critical distance negatively affected behavioral and subjective listening effort. This study extends understanding of listening effort in reverberant rooms by highlighting the effect of listener's position relative to the room's critical distance.
Abstract Summary: Scientists did a study to see how echoes in a room and how far away a person is from the person talking can make it harder to listen. They had 19 adults with good hearing do two tasks at the same time: figuring out words they heard and sorting words quickly. They tried this in a room with a little and a lot of echo and at different distances from the speaker. They found that more echoes and being farther away made it harder to understand words and made listening feel tougher, especially if the listener was farther than a certain point in the room. This research helps us know more about why it can be hard to listen in echoey places and why where you sit in a room matters.

Augmented reality as a novel approach for addiction treatment: development of a smoking cessation app.
Ann Med.
2022 Dec;
54(1):3096-3106.
Abstract: Augmented reality (AR) is a rapidly developing technology that has substantial potential as a novel approach for addiction treatment, including tobacco use. AR can facilitate the delivery of cue exposure therapy (CET) such that individuals can experience the treatment in their natural environments as viewed via a smartphone screen, addressing the limited generalizbility of extinction learning. Previously, our team developed a basic AR app for smoking cessation and demonstrated the necessary mechanisms for CET. Specifically, we showed that the AR smoking cues, compared to neutral cues, elicited substantial cue reactivity (i.e. increased urge) and that repeated exposure to the AR smoking cues reduced urge (i.e. extinction) in a laboratory setting. Here we report the next step in the systematic development of the AR app, in which we assessed the usability and acceptability of the app among daily smokers in their natural environments. Daily smokers ( = 23, 78.3% female, Mean Age = 43.4, Mean Cigarettes/Day = 14.9), not actively quitting, were instructed to use the AR app in locations and situations where they smoke (e.g. home, bar) at least 5 times per day over one week. The study is registered in clinicaltrials.gov (NCT04101422). Results indicated high usability and acceptability. Most of the participants (73.9%) used the AR app on at least 5 days. Participants found the AR cues realistic and well-integrated in their natural environments. The AR app was perceived as easy to use (Mean = 4.1/5) and learn (mean of 2 days to learn). Overall satisfaction with the app was also high. Secondary analyses found that 56.5% reported reduced smoking, with an average 26% reduction in cigarettes per day at follow-up. These findings set the stage for a randomized controlled trial testing the AR app as an adjuvant therapy for treating tobacco dependence, with potential applicability to other substances. KEY MESSAGEThis study found that the augmented reality (AR) smartphone application that utlized cue exposure treatment for smoking cessation was perceived as easy to use and learn in the natural, day-to-day environment of daily smokers. Findings set the stage for a larger clinical trial testing the AR app as an adjuvant therapy for treating tobacco dependence, with potential applicability to other addictive behaviors.
Abstract Summary: Scientists have created an app that uses augmented reality (AR) to help people quit smoking. The app works by showing smokers images that make them want to smoke (cues), and then helps them get used to these cues without smoking. In a test, daily smokers used the app in places where they usually smoke. The results were promising: most people found the app easy to use and realistic, and over half of them smoked less after using the app. This could be a new way to help people quit smoking, and maybe even other addictions. The next step is a bigger test to see how well the app works.

Abstract: To address the rising prevalence of Alzheimer's disease and related dementias, effective interventions that can be widely disseminated are warranted. The Preventing Alzheimer's with Cognitive Training study (PACT) investigates a commercially available computerized cognitive training program targeting improved Useful Field of View Training (UFOVT) performance. The primary goal is to test the effectiveness of UFOVT to reduce incidence of clinically defined mild cognitive impairment (MCI) or dementia with a secondary objective to examine if effects are moderated by plasma β-amyloid level or apolipoprotein E e4 (APOE e4) allele status. This multisite study utilizes a randomized, controlled experimental design with blinded assessors and investigators. Individuals who are 65 years of age and older are recruited from the community. Eligible participants who demonstrate intact cognitive status (Montreal Cognitive Assessment score > 25) are randomized and asked to complete 45 sessions of either a commercially available computerized-cognitive training program (UFOVT) or computerized games across 2.5 years. After three years, participants are screened for cognitive decline. For those demonstrating decline or who are part of a random subsample, a comprehensive neuropsychological assessment is completed. Those who perform below a pre-specified level are asked to complete a clinical evaluation, including an MRI, to ascertain clinical diagnosis of normal cognition, MCI, or dementia. Participants are asked to provide blood samples for analyses of Alzheimer's disease related biomarkers. The PACT study addresses the rapidly increasing prevalence of dementia. Computerized cognitive training may provide a non-pharmaceutical option for reducing incidence of MCI or dementia to improve public health. The PACT study is registered at http://Clinicaltrials.govNCT03848312.
Abstract Summary: Scientists are studying a computer program to see if it can help older people's brains stay sharp and possibly prevent memory problems like Alzheimer's disease. People who are 65 or older and still have good thinking skills can join the study. They will either play special brain-training games or other computer games for a while. After three years, the researchers will check to see if their brains are still working well. They will also look at their blood to find clues about brain health. This study is important because it might give us a new way to keep our brains healthy without using medicine.

80(18):1721-1731.
Abstract: People with type 2 diabetes mellitus (T2DM) have elevated cardiovascular (CV) risk, including for hospitalization for heart failure (HHF). Canagliflozin reduced CV and kidney events in patients with T2DM and high CV risk or nephropathy in the CANVAS (CANagliflozin cardioVascular Assessment Study) Program and the CREDENCE (Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation) trial. The aim of this study was to assess the effects of canagliflozin on CV outcomes according to baseline estimated glomerular filtration rate (eGFR) and urine albumin:creatinine ratio (UACR) in pooled patient-level data from the CANVAS Program and CREDENCE trial. Canagliflozin effects on CV death or HHF were assessed by baseline eGFR (<45, 45-60, and >60 mL/min/1.73 m) and UACR (<30, 30-300, and >300 mg/g). HRs and 95% CIs were estimated by using Cox regression models overall and according to subgroups. A total of 14,543 participants from the CANVAS Program (N = 10,142) and the CREDENCE (N = 4,401) trial were included, with a mean age of 63 years, 35% female, 75% White, 13.2% with baseline eGFR <45 mL/min/1.73 m, and 31.9% with UACR >300 mg/g. Rates of CV death or HHF increased as eGFR declined and/or UACR increased. Canagliflozin significantly reduced CV death or HHF compared with placebo (19.4 vs 28.0 events per 1,000 patient-years; HR: 0.70; 95% CI: 0.62-0.79), with consistent results across eGFR and UACR categories (all P interaction >0.40). Risk of CV death or HHF was higher in those with lower baseline eGFR and/or higher UACR. Canagliflozin consistently reduced CV death or HHF in participants with T2DM and high CV risk or nephropathy regardless of baseline renal function or level of albuminuria. (Canagliflozin Cardiovascular Assessment Study [CANVAS], NCT01032629; A Study of the Effects of Canagliflozin [JNJ-24831754] on Renal Endpoints in Adult Participants With Type 2 Diabetes Mellitus [CANVAS-R], NCT01989754; and Evaluation of the Effects of Canagliflozin on Renal and Cardiovascular Outcomes in Participants With Diabetic Nephropathy [CREDENCE], NCT02065791).
Abstract Summary: Scientists did a study to see if a medicine called canagliflozin helps people with type 2 diabetes who are at risk for heart problems, including heart failure. They looked at two big studies with over 14,000 people to see if canagliflozin could help prevent death from heart issues or stop people from having to go to the hospital for heart failure. They checked how well the people's kidneys were working and how much of a certain protein was in their urine, because these can affect heart health. They found that canagliflozin helped reduce these heart problems for all different types of people with diabetes, no matter how well their kidneys were working or how much protein was in their urine. This is good news because it means this medicine can help lots of people with diabetes stay healthier and avoid serious heart problems.

11(9):e37823.
Abstract: Nonpharmacologic mind-body therapies have demonstrated efficacy in low back pain. However, the mechanisms underlying these therapies remain to be fully elucidated. In response to these knowledge gaps, the Stanford Center for Low Back Pain-a collaborative, National Institutes of Health P01-funded, multidisciplinary research center-was established to investigate the common and distinct biobehavioral mechanisms of three mind-body therapies for chronic low back pain: cognitive behavioral therapy (CBT) that is used to treat pain, mindfulness-based stress reduction (MBSR), and electroacupuncture. Here, we describe the design and implementation of the center structure and the associated randomized controlled trials for characterizing the mechanisms of chronic low back pain treatments. The multidisciplinary center is running two randomized controlled trials that share common resources for recruitment, enrollment, study execution, and data acquisition. We expect to recruit over 300 chronic low back pain participants across two projects and across different treatment arms within each project. The first project will examine pain-CBT compared with MBSR and a wait-list control group. The second project will examine real versus sham electroacupuncture. We will use behavioral, psychophysical, physical measure, and neuroimaging techniques to characterize the central pain modulatory and emotion regulatory systems in chronic low back pain at baseline and longitudinally. We will characterize how these interventions impact these systems, characterize the longitudinal treatment effects, and identify predictors of treatment efficacy. Participant recruitment began on March 17, 2015, and will end in March 2023. Recruitment was halted in March 2020 due to COVID-19 and resumed in December 2021. This center uses a comprehensive approach to study chronic low back pain. Findings are expected to significantly advance our understanding in (1) the baseline and longitudinal mechanisms of chronic low back pain, (2) the common and distinctive mechanisms of three mind-body therapies, and (3) predictors of treatment response, thereby informing future delivery of nonpharmacologic chronic low back pain treatments. ClinicalTrials.gov NCT02503475; https://clinicaltrials.gov/ct2/show/NCT02503475. PRR1-10.2196/37823.
Abstract Summary: Scientists at the Stanford Center for Low Back Pain are studying how different treatments without medicine can help people with long-lasting back pain. They are looking at three kinds of treatments: a special talking therapy called cognitive behavioral therapy (CBT), a relaxation technique called mindfulness, and a treatment with needles called electroacupuncture. They want to understand better how these treatments work and why they help some people more than others.
They are doing two big studies with over 300 people to compare these treatments and see what changes happen in the body and brain. They stopped the study for a while because of the virus that was making people sick, but they started again and will finish in March 2023.
The results will help us know more about back pain and how to treat it without using medicine, which could be really good for lots of people with back pain. The study is listed on a website called ClinicalTrials.gov with the number NCT02503475.

Gender differences in the experience of interstitial cystitis/bladder pain syndrome.

Abstract: This study assessed gender differences in a debilitating urologic pain condition, interstitial cystitis/bladder pain syndrome (IC/BPS). We aimed to (1) evaluate how pain, symptom, and distress profiles of IC/BPS may differ between genders and (2) obtain in-depth firsthand accounts from patients to provide additional insight into their experiences that may explain potential gender differences. A mixed methods approach combined validated patient-reported outcome measures with a single timepoint 90-min focus group. Tests of summary score group differences between men and women were assessed across questionnaires measuring urologic symptoms, pain, emotional functioning, and diagnostic timeline. Qualitative analysis applied an inductive-deductive approach to evaluate and compare experiences of living with IC/BPS Group narratives were coded and evaluated thematically by gender using the biopsychosocial model, providing insight into the different context of biopsychosocial domains characterizing the male and female experience of IC/BPS. Thirty-seven participants [women ( = 27) and men ( = 10)] completed measures and structured focus group interviews across eight group cohorts conducted from 8/2017 to 3/2019. Women reported greater pain intensity ( = 0.043) and extent ( = 0.018), but not significantly greater impairment from pain ( = 0.160). Levels of psychological distress were significantly elevated across both genders. Further, the duration between time of pain symptom onset and time to diagnosis was significantly greater for women than men ( = 0.012). Qualitative findings demonstrated key distinctions in experiences between genders. Men appeared not to recognize or to deter emotional distress while women felt overwhelmed by it. Men emphasized needing more physiological treatment options whilst women emphasized needing more social and emotional support. Interactions with medical providers and the healthcare system differed substantially between genders. While men reported feeling supported and involved in treatment decisions, women reported feeling dismissed and disbelieved. The findings indicate different pain experiences and treatment needs between genders in persons experiencing urologic pain and urinary symptoms, with potential intervention implications. Results suggest gender health inequality in medical interactions in this urologic population needing further investigation.
Abstract Summary: Scientists did a study to learn if men and women feel and deal with a bladder pain condition differently. They asked 37 people with this condition to answer questions and talk in groups about their pain and feelings. They found that women had more intense pain and waited longer to get help from doctors than men. Men and women both felt a lot of emotional stress, but they handled it in different ways. Men wanted more medical treatments, while women wanted more support from people around them. Also, women often felt that doctors didn't take their pain seriously, but men felt like doctors helped them make choices about their treatment. This study shows that men and women with bladder pain might need different kinds of help, and it's important to understand these differences to make sure everyone gets the right care.

Memantine for autism spectrum disorder.
The Cochrane database of systematic reviews (2022)

Memantine for autism spectrum disorder.
Cochrane Database Syst Rev.
2022 Aug 25;
8(8):CD013845.
Abstract: Autism spectrum disorder (ASD; also known as autism) is a developmental disability that begins in childhood and is typically seen in around 1% to 2% of children. It is characterised by social communication difficulties and repetitive and restricted behaviours and routines that can have a negative impact on a child's quality of life, achievement at school, and social interactions with others. It has been hypothesised that memantine, which is traditionally used to treat dementia, may be effective in reducing the core symptoms of autism as well as some co-occurring symptoms such as hyperactivity and language difficulties. If memantine is being used to treat the core symptoms of autism, it is important to review the evidence of its effectiveness. To assess the effects of memantine on the core symptoms of autism, including, but not limited to, social communication and stereotypical behaviours. We searched CENTRAL, MEDLINE, Embase, nine other databases and three trials registers up to February 2022. We also checked reference lists of key studies and checked with experts in the field for any additional papers. We searched for retractions of the included studies in MEDLINE, Embase, and the Retraction Watch Database. No retractions or corrections were found. We included randomised controlled trials (RCTs) of any dose of memantine compared with placebo in autistic people. We also included RCTs in which only one group received memantine, but both groups received the same additional therapy (e.g. a behaviour intervention). We used standard Cochrane methods. Our primary outcomes were core autism symptoms and adverse effects. Secondary outcomes were language, intelligence, memory, adaptive behaviour, hyperactivity, and irritability. We used GRADE to assess certainty of evidence. We included three RCTs (two double-blind and one single-blind) with 204 participants that examined the short-term effect (immediately postintervention) of memantine in autistic people. Two studies took place in the USA and the other in Iran. All three studies focused on children and adolescents, with a mean age of 9.40 (standard deviation (SD) 2.26) years. Most participants were male (range across studies 73% to 87%). The diagnosis of ASD was based on the Diagnostic and Statistical Manual of Mental Disorders (4th edition; 4th edition, text revision; or 5th edition). To confirm the diagnosis, one study used the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview-Revised (ADI-R); one used ADOS, ADI-R or the Autism Diagnostic Interview Screener; and one used the Gilliam Autism Rating Scale. Dosage of memantine was based on the child's weight and ranged from 3 mg to 15 mg per day. Comparisons Two studies examined memantine compared with placebo; in the other study, both groups had a behavioural intervention while only one group was given memantine. Risk of bias All studies were rated at high risk of bias overall, as they were at high or unclear risk of bias across all but four domains in one study, and all but two domains in the other two studies. One study was funded by Forest Laboratories, LLC, (Jersey City, New Jersey), Allergan. The study sponsor was involved in the study design, data collection (via contracted clinical investigator sites), analysis and interpretation of data, and the decision to present these results. The other two studies reported no financial support or sponsorship; though in one of the two, the study medication was an in-kind contribution from Forest Pharmaceuticals. Primary outcomes There was no clear evidence of a difference between memantine and placebo with respect to severity of core symptoms of autism, although we are very uncertain about the evidence. The standardised mean difference in autism symptoms score in the intervention group versus the control group was -0.74 standard deviations (95% confidence interval (CI) -2.07 to 0.58; 2 studies, 181 participants; very low-certainty evidence; medium effect size); lower scores indicate less severe autistic symptoms. Two studies (144 participants) recorded adverse effects that the authors deemed related to the study and found there may be no difference between memantine and placebo (odds ratio (OR) 0.64, 95% CI 0.17 to 2.39; low-certainty evidence). Secondary outcomes There may be no difference between memantine and placebo on language (2 studies, 144 participants; low-certainty evidence); memory or adaptive behaviour (1 study, 23 participants; both low-certainty evidence); or hyperactivity or irritability (1 study, 121 participants; both low-certainty evidence). It is unclear whether memantine is an effective treatment for autistic children. None of the three included trials reported on the effectiveness of memantine in adults. Further studies using rigorous designs, larger samples, longer follow-up and clinically meaningful outcome measures that are important to autistic people and their families will strengthen our knowledge of the effects of memantine in autism.
Abstract Summary: Scientists wanted to see if a medicine called memantine, which is usually used for memory problems, could help kids with autism. Autism is when kids have trouble talking and making friends, and they might do the same things over and over. The scientists looked at three studies with 204 kids to see if memantine could make their autism symptoms better. They also checked if the medicine caused any bad reactions.
The studies weren't perfect, and the scientists couldn't be sure if memantine really helped with autism symptoms or not. They also didn't find a big difference in how the kids talked, remembered things, or behaved. Some kids had side effects, but it seemed similar to kids who didn't take the medicine.
In the end, the scientists said they don't know if memantine is good for treating kids with autism. They need to do more and better studies to find out. They didn't study adults with autism, so they don't know if it would help them either.

Abstract: Fibromyalgia syndrome (FMS) is a leading cause of functional limitations and disability for which there is no cure. Positive psychological interventions for improving health have received increasing attention, but evidence of the feasibility, acceptability, and impact of such interventions in adult populations with FMS is limited. To describe the rationale and design of a 5-week, online positive affect skills intervention, LARKSPUR: Lessons in Affect Regulation to Keep Stress and Pain UndeR control. FMS participants (N = 90) will be randomized to one of two conditions: (1) LARKSPUR or (2) emotion reporting/attention control. LARKSPUR is an online multicomponent intervention that targets eight skills to help foster positive affect: (1) noticing positive events, (2) savoring positive events, (3) identifying personal strengths, (4) behavioral activation to set and work toward attainable goals, (5) mindfulness, (6) positive reappraisal, (7) gratitude, and (8) acts of kindness. The primary outcomes include feasibility (i.e., recruitment, retention, adherence) and acceptability (i.e., helpfulness, usability, satisfaction). Secondary outcomes include pain intensity and pain interference. If feasibility and acceptability metrics are met and reductions in pain outcomes are achieved, we will undertake future efficacy and effectiveness trials of LARKSPUR among older adults with FMS. NCT04869345.
Abstract Summary: This study is about a new online program called LARKSPUR that helps adults with fibromyalgia, a condition that causes pain and disability, to manage their stress and pain. The program teaches eight skills, like noticing good things, being grateful, and setting achievable goals. The study will have 90 participants who will either use LARKSPUR or another method. The researchers will see if people like using the program, if they stick with it, and if it helps reduce their pain. If it works well, they plan to test it with more people in the future. This could be a new way to help people with fibromyalgia.

Abstract: Re-aligning eating patterns with biological rhythm can reduce the burden of metabolic syndrome in older adults with overweight or obesity. Time-restricted eating (TRE) has been shown to result in weight loss and improved cardiometabolic health while being less challenging than counting calories. The New York Time-Restricted EATing study (NY-TREAT) is a two-arm, randomized clinical trial (RCT) that aims to examine the efficacy and sustainability of TRE (eating window ≤10 h/day) vs. a habitual prolonged eating window (HABIT, ≥14 h/day) in metabolically unhealthy midlife adults (50-75 years) with overweight or obesity and prediabetes or type 2 diabetes (T2D). Our primary hypothesis is that the TRE will result in greater weight loss compared to HABIT at 3 months. The efficacy of the TRE intervention on body weight, fat mass, energy expenditure, and glucose is tested at 3 months, and the sustainability of its effect is measured at 12 months, with ambulatory assessments of sleep and physical activity (ActiGraph), eating pattern (smartphone application), and interstitial glucose (continuous glucose monitoring). The RCT also includes state-of-the-art measurements of body fat (quantitative magnetic resonance), total energy expenditure (doubly-labelled water), insulin secretion, insulin resistance, and glucose tolerance. Adherence to self-monitoring and reduced eating window are monitored remotely in real-time. This RCT will provide further insight into the effects of TRE on cardiometabolic health in individuals with high metabolic risk. Sixty-two participants will be enrolled, and with estimated 30% attrition, 42 participants will return at 12 months. This protocol describes the design, interventions, methods, and expected outcomes. Clinical trial registration:NCT04465721 IRB: AAAS7791.
Abstract Summary: Scientists are doing a study to see if eating for only 10 hours a day can help older people who are a bit too heavy and have health problems like high blood sugar or diabetes. They are comparing this to people who eat over a longer time, like 14 hours a day. They think that eating for less time each day might help people lose weight after 3 months. They will check on things like how much body fat and sugar in the blood the people have, and they will keep an eye on how well they stick to the eating plan. They will also see if the good changes last for a whole year. This study could teach us if eating for a shorter time each day is good for people's health, especially for those who have a higher chance of getting heart disease or diabetes. They plan to have 62 people in the study, but they expect that some might not finish, so they hope to have at least 42 people at the end of the year.

Abstract: Background The sodium-glucose cotransporter 2 inhibitor canagliflozin reduced the risk of first cardiovascular composite events in the CREDENCE (Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation) trial. In this post hoc analysis, we evaluated the effect of canagliflozin on total (first and recurrent) cardiovascular events. Methods and Results The CREDENCE trial compared canagliflozin or matching placebo in 4401 patients with type 2 diabetes, albuminuria, and estimated glomerular filtration rate of 30 to <90 mL/min per 1.73 m, over a median of 2.6 years. The primary outcome was analyzed as a composite of any cardiovascular event including myocardial infarction, stroke, hospitalization for heart failure, hospitalization for unstable angina, and cardiovascular death. Negative binomial regression models were used to assess the effect of canagliflozin on the net burden of cardiovascular events. During the trial, 634 patients had 883 cardiovascular events, of whom 472 (74%) had just 1 cardiovascular event and 162 (26%) had multiple cardiovascular events. Canagliflozin reduced first cardiovascular events by 26% (hazard ratio, 0.74 [95% CI, 0.63-0.86]; <0.001) and total cardiovascular events by 29% (incidence rate ratio, 0.71 [95% CI, 0.59-0.86]; <0.001). The absolute risk difference per 1000 patients treated over 2.5 years was -44 (95% CI, -67 to -21) first cardiovascular events and -73 (95% CI, -114 to -33) total events. Conclusions Canagliflozin reduced cardiovascular events, with a larger absolute benefit for total cardiovascular than first cardiovascular events. These findings provide further support for the benefit of continuing canagliflozin therapy after an initial event to prevent recurrent cardiovascular events. Registration Information URL: https://www.clinicaltrials.gov; Unique Identifier: NCT02065791.
Abstract Summary: Scientists did a study to see if a medicine called canagliflozin could help people with type 2 diabetes who also have heart problems. They tested this medicine on over 4,000 patients for about 2.5 years. They found that this medicine reduced the number of heart problems by 26% for first-time issues and 29% for repeated issues. This means that for every 1,000 patients who took the medicine for 2.5 years, there were 44 fewer first-time heart problems and 73 fewer total heart problems. This shows that canagliflozin can help prevent heart problems in people with type 2 diabetes.

Abstract: Mood-stabilizing medications are a cornerstone of treatment for people with bipolar disorder, though approximately half of these individuals are poorly adherent with their medication, leading to negative and even severe health consequences. While a variety of approaches can lead to some improvement in medication adherence, there is no single approach that has superior adherence enhancement and limited data on how these approaches can be implemented in clinical settings. Existing data have shown an increasing need for virtual delivery of care and interactive telemedicine interventions may be effective in improving adherence to long-term medication. Customized adherence enhancement (CAE) is a brief, practical bipolar-specific approach that identifies and targets individual patient adherence barriers for intervention using a flexibly administered modular format that can be delivered via telehealth communications. CAE is comprised of up to four standard treatment modules including Psychoeducation, Communication with Providers, Medication Routines, and Modified Motivational Interviewing. Participants will attend assigned module sessions with an interventionist based on their reasons for non-adherence and will be assessed for adherence, functioning, bipolar symptoms, and health resource use across a 12-month period. Qualitative and quantitative data will also be collected to assess barriers and facilitators to CAE implementation and reach and adoption of CAE among clinicians in the community. The proposed study addresses the need for practical adherence interventions that are effective, flexible, and designed to adapt to different settings and patients. By focusing on a high-risk, vulnerable group of people with bipolar disorder, and refining an evidence-based approach that will integrate into workflow of public-sector care and community mental health clinics, there is substantial potential for improving bipolar medication adherence and overall health outcomes on a broad level. The study was registered on ClinicalTrials.gov NCT04622150 on November 9, 2020.
Abstract Summary: Doctors give special medicines to help people with bipolar disorder feel better, but about half of these people have trouble taking their medicine regularly. This can make their health worse. The study is trying to find a good way to help people take their medicine through the internet and phone calls. They made a special program that helps each person with the problems they have in taking their medicine. The program has four parts, like learning about the illness, talking better with doctors, making a medicine routine, and getting motivated. People in the study will get help from a helper and will be checked for a year to see if they are taking their medicine and feeling better. The study will also look at how easy it is to use this program in real-life doctor's offices. This could help lots of people with bipolar disorder take their medicine and be healthier. The study's details are on a website called ClinicalTrials.gov with the number NCT04622150.

Examination of pubertal timing and tempo in females and males with autism spectrum disorder compared to typically developing youth.
Autism Res.
2022 Oct;
15(10):1894-1908.
Abstract: Autism spectrum disorder (ASD) is characterized by impaired social communication and poor adaptation to change; thus, pubertal development may be precarious. Pubertal timing and tempo were measured in 244 youth (7.9% Black, 83.3% White, and 8.7% multiracial) with ASD (N = 140) and typical development (N = 104). Pubertal development was measured using Tanner staging of Genital (G, males), Breast (B, females), and pubic hair (PH) in both sexes at Year 1 (10-13 years), Year 2 (11-14 years), and Year 3 (12-15 years). Nonlinear mixed effects models analyzed interindividual differences in timing and tempo. For both sexes, ASD and higher body mass index were associated with earlier pubertal timing. Males generally exhibited faster tempo than females. Linear regression models did not show associations between pubertal timing and internalizing symptoms at time three. Findings showing advanced pubertal maturation in ASD youth suggest greater risk of psychological, social, and physiological challenges. LAY SUMMARY: Youth with ASD have difficulty in social communication and adaption to change, thus puberty may be a challenging transition. The study examined onset (timing) and progression (tempo) of puberty over three years, using physical exam, in 244 adolescents with and without ASD, enrolled at ages 10-13. ASD youth started puberty earlier, while males generally progressed at a faster pace. Further examination of puberty in ASD should identify impact on social, behavioral, and mental health outcomes.
Abstract Summary: Scientists studied how kids with Autism Spectrum Disorder (ASD) and kids without it go through puberty. They looked at 244 kids over three years to see when they started puberty and how fast they went through the changes. They found that kids with ASD started puberty earlier, and boys went through changes faster than girls. This study is important because it shows that kids with ASD might face more challenges when they grow up, and we need to understand how this affects their lives and health.

Abstract: Cue-exposure therapy (CET) aims to extinguish conditioned cue reactivity (CR) to aid in smoking cessation. A key disadvantage of extant CET is its limited ability to generalize extinction to the real world. Our team developed a set of augmented reality smoking-related and neutral cues that can appear in real-time in smokers' natural environments as viewed through a smartphone screen. Prior to deployment as a clinical tool, the present study tested the ability of AR smoking cues to extinguish CR in a controlled laboratory study with an AR smartphone application developed for this project. We hypothesized that daily smokers who completed a single session of cue exposure with AR smoking cues (extinction condition) would demonstrate lower cue-provoked urge to smoke at posttest compared to those who viewed AR neutral cues (control condition). Daily smokers ( = 129, 46.5% female, = 47.6, = 19.1) in acute abstinence were randomized to either the extinction or control condition comprising 28 AR trials. As hypothesized, we found a Time × Condition interaction indicating that posttest urge ratings were lower in the extinction condition than in the control condition ( = .034). A secondary hypothesis that participants in the extinction condition would show a longer latency to smoke when provided a cigarette was not supported. These laboratory findings provide evidence supporting the potential clinical efficacy of AR cues for cue-exposure trials, setting the stage for testing in smokers' naturalistic environments.

Abstract Summary: This study was about helping people quit smoking using a new tool on their smartphones. The researchers created a special app that shows images related to smoking or neutral images. They thought that showing smokers these images might help reduce their desire to smoke. They tested this idea with 129 smokers. The results showed that those who saw the smoking-related images had less desire to smoke afterwards compared to those who saw neutral images. However, seeing these images didn't make them wait longer before smoking again. This study suggests that this app could be a useful tool to help people quit smoking.

Interventions for interpersonal communication about end of life care between health practitioners and affected people.

Abstract: Communication about end of life (EoL) and EoL care is critically important for providing quality care as people approach death. Such communication is often complex and involves many people (patients, family members, carers, health professionals). How best to communicate with people in the period approaching death is not known, but is an important question for quality of care at EoL worldwide. This review fills a gap in the evidence on interpersonal communication (between people and health professionals) in the last year of life, focusing on interventions to improve interpersonal communication and patient, family member and carer outcomes. To assess the effects of interventions designed to improve verbal interpersonal communication about EoL care between health practitioners and people affected by EoL. We searched CENTRAL, MEDLINE, Embase, PsycINFO, and CINAHL from inception to July 2018, without language or date restrictions. We contacted authors of included studies and experts and searched reference lists to identify relevant papers. We searched grey literature sources, conference proceedings, and clinical trials registries in September 2019. Database searches were re-run in June 2021 and potentially relevant studies listed as awaiting classification or ongoing. This review assessed the effects of interventions, evaluated in randomised and quasi-randomised trials, intended to enhance interpersonal communication about EoL care between patients expected to die within 12 months, their family members and carers, and health practitioners involved in their care. Patients of any age from birth, in any setting or care context (e.g. acute catastrophic injury, chronic illness), and all health professionals involved in their care were eligible. All communication interventions were eligible, as long as they included interpersonal interaction(s) between patients and family members or carers and health professionals. Interventions could be simple or complex, with one or more communication aims (e.g. to inform, skill, engage, support). Effects were sought on outcomes for patients, family and carers, health professionals and health systems, including adverse (unintended) effects. To ensure this review's focus was maintained on interpersonal communication in the last 12 months of life, we excluded studies that addressed specific decisions, shared or otherwise, and the tools involved in such decision-making. We also excluded studies focused on advance care planning (ACP) reporting ACP uptake or completion as the primary outcome. Finally, we excluded studies of communication skills training for health professionals unless patient outcomes were reported as primary outcomes. Standard Cochrane methods were used, including dual review author study selection, data extraction and quality assessment of the included studies. Eight trials were included. All assessed intervention effects compared with usual care. Certainty of the evidence was low or very low. All outcomes were downgraded for indirectness based on the review's purpose, and many were downgraded for imprecision and/or inconsistency. Certainty was not commonly downgraded for methodological limitations. A summary of the review's findings is as follows. Knowledge and understanding (four studies, low-certainty evidence; one study without usable data): interventions to improve communication (e.g. question prompt list, with or without patient and physician training) may have little or no effect on knowledge of illness and prognosis, or information needs and preferences, although studies were small and measures used varied across trials. Evaluation of the communication (six studies measuring several constructs (communication quality, patient-centredness, involvement preferences, doctor-patient relationship, satisfaction with consultation), most low-certainty evidence): across constructs there may be minimal or no effects of interventions to improve EoL communication, and there is uncertainty about effects of interventions such as a patient-specific feedback sheet on quality of communication. Discussions of EoL or EoL care (six studies measuring selected outcomes, low- or very low-certainty evidence): a family conference intervention may increase duration of EoL discussions in an intensive care unit (ICU) setting, while use of a structured serious illness conversation guide may lead to earlier discussions of EoL and EoL care (each assessed by one study). We are uncertain about effects on occurrence of discussions and question asking in consultations, and there may be little or no effect on content of communication in consultations. Adverse outcomes or unintended effects (limited evidence): there is insufficient evidence to determine whether there are adverse outcomes associated with communication interventions (e.g. question prompt list, family conference, structured discussions) for EoL and EoL care. Patient and/or carer anxiety was reported by three studies, but judged as confounded. No other unintended consequences, or worsening of desired outcomes, were reported. Patient/carer quality of life (four studies, low-certainty evidence; two without useable data): interventions to improve communication may have little or no effect on quality of life. Health practitioner outcomes (three studies, low-certainty evidence; two without usable data): interventions to improve communication may have little or no effect on health practitioner outcomes (satisfaction with communication during consultation; one study); effects on other outcomes (knowledge, preparedness to communicate) are unknown. Health systems impacts: communication interventions (e.g. structured EoL conversations) may have little or no effect on carer or clinician ratings of quality of EoL care (satisfaction with care, symptom management, comfort assessment, quality of care) (three studies, low-certainty evidence), or on patients' self-rated care and illness, or numbers of care goals met (one study, low-certainty evidence). Communication interventions (e.g. question prompt list alone or with nurse-led communication skills training) may slightly increase mean consultation length (two studies), but other health service impacts (e.g. hospital admissions) are unclear. Findings of this review are inconclusive for practice. Future research might contribute meaningfully by seeking to fill gaps for populations not yet studied in trials; and to develop responsive outcome measures with which to better assess the effects of communication on the range of people involved in EoL communication episodes. Mixed methods and/or qualitative research may contribute usefully to better understand the complex interplay between different parties involved in communication, and to inform development of more effective interventions and appropriate outcome measures. Co-design of such interventions and outcomes, involving the full range of people affected by EoL communication and care, should be a key underpinning principle for future research in this area.
Abstract Summary: This study looked at how to improve conversations between doctors, patients, and families about end-of-life care. The researchers looked at different ways to help these conversations, like using a list of questions or giving feedback to doctors. They found that these methods might not make a big difference in how much people understand about their illness, how they feel about their conversations with doctors, or their quality of life. They also didn't find any bad effects from these methods. The researchers think more studies are needed to find the best ways to help these important conversations. This could help make sure people get the best care when they are very sick.

Abstract: Interoception refers to the sensing, interpretation, integration, and regulation of signals about the body's internal physiological state. Interoceptive sensibility is the subjective evaluation of interoceptive experience, as assessed by self-report measures, and is abnormal in numerous neuropsychiatric disorders. Research examining interoceptive sensibility in individuals with chronic tic disorders (CTDs), however, has yielded conflicting results, likely due to methodologic differences between studies and small sample sizes. We sought to compare interoceptive sensibility between adults with CTD and healthy controls, adjusting for co-occurring psychiatric symptoms, and to examine the relationship of interoceptive sensibility with other CTD clinical features, in particular, premonitory urge. We recruited adults with CTDs and sex- and age-matched healthy controls to complete the Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2), as well as a battery of measures assessing psychiatric symptoms prevalent in CTD populations. CTD participants additionally completed scales quantifying tic severity, premonitory urge severity, and health-related quality of life. We conducted between-group contrasts (Wilcoxon rank-sum test) for each MAIA-2 subscale, analyzed the effect of psychiatric symptoms on identified between-group differences (multivariable linear regression), and examined within-group relationships between MAIA-2 subscales and other clinical measures (Spearman rank correlations, multivariable linear regression). Between adults with CTD ( = 48) and healthy controls ( = 48), MAIA-2 Noticing and Not-Worrying subscale scores significantly differed. After adjusting for covariates, lower MAIA-2 Not-Worrying subscale scores were significantly associated with female sex (β = 0.42, < 0.05) and greater severity of obsessive-compulsive symptoms (β = -0.028, < 0.01), but not with CTD diagnosis. After adjusting for severity of tics and obsessive-compulsive symptoms, a composite of MAIA-2 Noticing, Attention Regulation, Emotional Awareness, Self-Regulation, Body Listening, and Trusting subscales (β = 2.52, < 0.01) was significantly associated with premonitory urge. Study results revealed three novel findings: adults with CTD experience increased anxiety-associated somatization and increased general body awareness relative to healthy controls; anxiety-associated somatization is more closely associated with sex and obsessive-compulsive symptoms than with CTD diagnosis; and increased general body awareness is associated with greater severity of premonitory urges.
Abstract Summary: Scientists did a study to learn about how well people with chronic tic disorders (CTDs) can feel and understand what's happening inside their bodies, like when their heart beats fast or they feel hungry. This is called "interoceptive sensibility." They compared these people to healthy people without tics. They asked everyone questions about how they notice and think about these body feelings and also checked for other mental health symptoms.
They found that people with tics were more aware of their bodies and felt more anxious about body sensations than the healthy people. Women and people with obsessive-compulsive symptoms felt more anxious about body sensations, but this wasn't just because of their tics. Also, people with tics who were more aware of their bodies tended to feel stronger urges before their tics happened.
This study helps us understand that people with tics might feel things in their bodies differently, and this can be linked to how strong their urges to tic are. This could help doctors and therapists find better ways to help people with tics.

Increase in BNP in Response to Endothelin-Receptor Antagonist Atrasentan Is Associated With Incident Heart Failure.
JACC Heart Fail.
2022 Jul;
10(7):498-507.
Abstract: The endothelin receptor antagonist atrasentan reduced the risk of kidney failure in patients with type 2 diabetes mellitus and chronic kidney disease (CKD) in the SONAR (Study of Diabetic Nephropathy with Atrasentan) trial, although with a numerically higher incidence of heart failure (HF) hospitalization. The purpose of this study was to assess if early changes in B-type natriuretic peptide (BNP) and body weight during atrasentan treatment predict HF risk. Participants with type 2 diabetes and CKD entered an open-label enrichment phase to assess response to atrasentan 0.75 mg/day. Participants without substantial fluid retention (>3 kg body weight increase or BNP increase to >300 pg/mL), were randomized to atrasentan 0.75 mg/day or placebo. Cox proportional hazards regression was used to assess the effects of atrasentan vs placebo on the prespecified safety outcome of HF hospitalizations. Among 3,668 patients, 73 (4.0%) participants in the atrasentan and 51 (2.8%) in the placebo group developed HF (HR: 1.39; 95% CI: 0.97-1.99; P = 0.072). In a multivariable analysis, HF risk was associated with higher baseline BNP (HR: 2.32; 95% CI: 1.81-2.97) and percent increase in BNP during response enrichment (HR: 1.46; 95% CI: 1.08-1.98). Body weight change was not associated with HF. Exclusion of patients with at least 25% BNP increase during enrichment attenuated the risk of HF with atrasentan (HR: 1.02; 95% CI: 0.66-1.56) while retaining nephroprotective effects (HR: 0.58; 95% CI: 0.44-0.78). In patients with type 2 diabetes and CKD, baseline BNP and early changes in BNP in response to atrasentan were associated with HF hospitalization, highlighting the importance of natriuretic peptide monitoring upon initiation of atrasentan treatment. (Study Of Diabetic Nephropathy With Atrasentan [SONAR]; NCT01858532).
Abstract Summary: Doctors did a study to see if a medicine called atrasentan could help people with type 2 diabetes and kidney disease avoid kidney failure. They found out that while it did help the kidneys, some patients had to go to the hospital for heart problems more often. They wanted to know if they could tell early on who might have heart issues by checking a heart-related substance in the blood called BNP and how much a person's weight changed. They gave some people the medicine and others a placebo (a pill with no medicine) and watched what happened. They found out that if a person's BNP went up a lot at the beginning, they were more likely to have heart problems. But, if they didn't let people with a big increase in BNP take the medicine, fewer had heart problems, and it still helped their kidneys. This means checking BNP when starting atrasentan could help doctors keep patients safe.

Abstract: To identify cognitive phenotypes in late-life depression (LLD) and describe relationships with sociodemographic and clinical characteristics. Observational cohort study. Baseline data from participants recruited via clinical referrals and community advertisements who enrolled in two separate studies. Non-demented adults with LLD ( = 120; mean age = 66.73 ± 5.35 years) and non-depressed elders ( = 56; mean age = 67.95 ± 6.34 years). All completed a neuropsychological battery, and individual cognitive test scores were standardized across the entire sample without correcting for demographics. Five empirically derived cognitive domain composites were created, and cluster analytic approaches (hierarchical, -means) were independently conducted to classify cognitive patterns in the depressed cohort only. Baseline sociodemographic and clinical characteristics were then compared across groups. A three-cluster solution best reflected the data, including "High Normal" ( = 47), "Reduced Normal" ( = 35), and "Low Executive Function" ( = 37) groups. The "High Normal" group was younger, more educated, predominantly Caucasian, and had fewer vascular risk factors and higher Mini-Mental Status Examination compared to "Low Executive Function" group. No differences were observed on other sociodemographic or clinical characteristics. Exploration of the "High Normal" group found two subgroups that only differed in attention/working memory performance and length of the current depressive episode. Three cognitive phenotypes in LLD were identified that slightly differed in sociodemographic and disease-specific variables, but not in the quality of specific symptoms reported. Future work on these cognitive phenotypes will examine relationships to treatment response, vulnerability to cognitive decline, and neuroimaging markers to help disentangle the heterogeneity seen in this patient population.
Abstract Summary: Scientists did a study to understand how older people with depression might think differently from those who aren't depressed. They looked at 120 older adults with depression and 56 without it. Everyone took some brain tests. The researchers found three different patterns of thinking in the people with depression. One group did really well on the tests, another was okay, and the last group had trouble with planning and doing things. The group that did well was younger, had more education, and was mostly white. They also had fewer health problems that affect blood vessels and scored higher on a simple brain test. The study found that even within the group that did well, there were some differences in how long they had been feeling depressed and how well they could pay attention. This research is important because it helps us understand that not all older adults with depression think the same way, and this could affect how they respond to treatment or how their thinking might change over time.

The effect of vitamin D supplementation on cardiovascular risk in patients with prediabetes: A secondary analysis of the D2d study.
J Diabetes Complications.
2022 Aug;
36(8):108230.
Abstract: Low blood 25(OH)D level is associated with increased cardiovascular disease (CVD) risk. Additionally, individuals with prediabetes are at higher risk for CVD than individuals with normoglycemia. We investigated the effects of vitamin D supplementation on CVD outcomes in the vitamin D and type 2 diabetes (D2d) study, a large trial among adults with prediabetes. 2423 participants were randomized to 4000 IU/day of vitamin D or placebo and followed for median 3.0 years for new-onset diabetes. In pre-specified secondary analyses, we examined the effect of vitamin D supplementation on composite Major Adverse Cardiovascular Events (MACE); expanded MACE (MACE + revascularization); atherosclerotic CVD (ASCVD) risk score; and individual CVD risk factors (blood pressure, lipids, high-sensitivity C-reactive protein). Cox models compared hazard ratios (HR) between the two groups on MACE and expanded MACE. Mean age was 60 years, 45 % were women, 13 % had history of CVD. Twenty-one participants assigned to vitamin D and 12 participants assigned to placebo met the MACE outcome (HR 1.81, 95%CI 0.89 to 3.69). There were 27 expanded MACE outcomes in each group (HR 1.02, 95%CI, 0.59 to 1.76). There were no significant differences between vitamin D and placebo in individual CVD risk factors, but change in ASCVD risk score favored the vitamin D group (-0.45 %, 95%CI -0.75 to -0.15). In people with prediabetes not selected for vitamin D insufficiency and with intermediate CVD risk, vitamin D supplementation did not decrease MACE but had a small favorable effect on ASCVD risk score. D2d ClinicalTrials.gov number, NCT01942694, prospectively registered September 16, 2013.
Abstract Summary: Scientists did a study to see if taking vitamin D could help people with a little bit of sugar problem (called prediabetes) avoid heart diseases. They gave 2423 adults either vitamin D or a fake pill (placebo) every day for about 3 years. They checked to see who got heart problems or diabetes. They found that taking vitamin D didn't really stop people from getting heart problems, but it did help a tiny bit in lowering the chance of getting heart diseases in the future. This study helps us understand that vitamin D might be a little helpful for heart health in people who are starting to have sugar problems.

Using the multiphase optimization strategy (MOST) framework to optimize an intervention to increase COVID-19 testing for Black and Latino/Hispanic frontline essential workers: A study protocol.
BMC Public Health.
2022 Jun 21;
22(1):1235.
Abstract: Among those at highest risk for COVID-19 exposure is the large population of frontline essential workers in occupations such food service, retail, personal care, and in-home health services, among whom Black and Latino/Hispanic persons are over-represented. For those not vaccinated and at risk for exposure to COVID-19, including frontline essential workers, regular (approximately weekly) COVID-19 testing is recommended. However, Black and Latino/Hispanic frontline essential workers in these occupations experience serious impediments to COVID-19 testing at individual/attitudinal- (e.g., lack of knowledge of guidelines), social- (e.g., social norms), and structural-levels of influence (e.g., poor access), and rates of testing for COVID-19 are insufficient. The proposed community-engaged study uses the multiphase optimization strategy (MOST) framework and an efficient factorial design to test four candidate behavioral intervention components informed by an integrated conceptual model that combines critical race theory, harm reduction, and self-determination theory. They are A) motivational interview counseling, B) text messaging grounded in behavioral economics, C) peer education, and D) access to testing (via navigation to an appointment vs. a self-test kit). All participants receive health education on COVID-19. The specific aims are to: identify which components contribute meaningfully to improvement in the primary outcome, COVID-19 testing confirmed with documentary evidence, with the most effective combination of components comprising an "optimized" intervention that strategically balances effectiveness against affordability, scalability, and efficiency (Aim 1); identify mediators and moderators of the effects of components (Aim 2); and use a mixed-methods approach to explore relationships among COVID-19 testing and vaccination (Aim 3). Participants will be N = 448 Black and Latino/Hispanic frontline essential workers not tested for COVID-19 in the past six months and not fully vaccinated for COVID-19, randomly assigned to one of 16 intervention conditions, and assessed at 6- and 12-weeks post-baseline. Last, N = 50 participants will engage in qualitative in-depth interviews. This optimization trial is designed to yield an effective, affordable, and efficient behavioral intervention that can be rapidly scaled in community settings. Further, it will advance the literature on intervention approaches for social inequities such as those evident in the COVID-19 pandemic. ClinicalTrials.gov: NCT05139927 ; Registered on 11/29/2021. Protocol version 1.0. May 2, 2022, Version 1.0.
Abstract Summary: Scientists are studying how to help people who work in places like restaurants, stores, and homes, especially Black and Latino/Hispanic workers, get tested for COVID-19 more often. These workers are more likely to catch the virus and often don't get tested enough. The study will try out different ways to encourage testing, like having talks to motivate them, sending helpful text messages, teaching through friends, and making tests easier to get. They want to find the best mix of these methods that works well and isn't too expensive. They will work with 448 workers who haven't been tested or vaccinated recently to see which methods help the most. They will also talk to 50 workers in more detail to understand better. This research could lead to better ways to keep people safe from COVID-19, especially those who have a higher chance of getting sick.

Youth with Down syndrome display widespread increased functional connectivity during rest.
Sci Rep.
2022 Jun 14;
12(1):9836.
Abstract: Studies of resting-state functional connectivity in young people with Down syndrome (DS) have yielded conflicting results. Some studies have found increased connectivity while others have found a mix of increased and decreased connectivity. No studies have examined whole-brain connectivity at the voxel level in youth with DS during an eyes-open resting-state design. Additionally, no studies have examined the relationship between connectivity and network selectivity in youth with DS. Thus, the current study sought to fill this gap in the literature. Nineteen youth with DS (M = 16.5; range 7-23; 13 F) and 33 typically developing (TD) youth (M = 17.5; range 6-24; 18 F), matched on age and sex, completed a 5.25-min eyes-open resting-state fMRI scan. Whole-brain functional connectivity (average Pearson correlation of each voxel with every other voxel) was calculated for each individual and compared between groups. Network selectivity was then calculated and correlated with functional connectivity for the DS group. Results revealed that whole-brain functional connectivity was significantly higher in youth with DS compared to TD controls in widespread regions throughout the brain. Additionally, participants with DS had significantly reduced network selectivity compared to TD peers, and selectivity was significantly related to connectivity in all participants. Exploratory behavioral analyses revealed that regions showing increased connectivity in DS predicted Verbal IQ, suggesting differences in connectivity may be related to verbal abilities. These results indicate that network organization is disrupted in youth with DS such that disparate networks are overly connected and less selective, suggesting a potential target for clinical interventions.
Abstract Summary: Scientists did a study to understand how the brains of young people with Down syndrome (DS) are connected when they are just resting and not doing any tasks. They looked at the brains of 19 young people with DS and compared them to 33 young people without DS. They used a special brain scan called fMRI while the participants were awake and resting. They found that the brains of those with DS had more connections in many areas compared to those without DS. Also, the brains of the DS group were not as good at keeping different brain networks separate. They noticed that the more the brain areas were connected, the better the verbal skills of the person with DS. This study helps us understand that the brains of young people with DS work differently, and this could lead to new ways to help them with their verbal skills.

Randomised, pragmatic, waitlist controlled trial of cannabis added to prescription opioid support on opioid dose reduction and pain in adults with chronic non-cancer pain: study protocol.
BMJ Open.
2022 Jun 9;
12(6):e064457.
Abstract: Chronic, non-cancer pain impacts approximately 50 million adults in the USA (20%), approximately 25% of whom receive chronic prescription opioids for pain despite limited empirical efficacy data and strong dose-related risk for opioid use disorder and opioid overdose. Also despite lack of efficacy data, there are many reports of people using cannabis products to manage chronic pain and replace or reduce chronic opioids. Here we describe the protocol for a randomised trial of the effect of cannabis, when added to a behavioural pain management and prescription opioid taper support programme, on opioid utilisation, pain intensity and pain interference. This is a pragmatic, single-blind, randomised, wait-list controlled trial that aims to enrol 250 adults taking prescription opioids at stable doses of ≥25 morphine milligram equivalents per day for chronic non-cancer pain who express interest in using cannabis to reduce their pain, their opioid dose or both. All participants will be offered a weekly, 24-session Prescription Opioid Taper Support group behavioural pain management intervention. Participants will be randomly assigned in 1:1 ratio to use cannabis products, primarily from commercial cannabis dispensaries or to abstain from cannabis use for 6 months. Coprimary outcomes are change in prescription monitoring programme-verified opioid dose and change in Pain, Enjoyment, General Activity scale scores. Secondary outcomes include quality of life, depression, anxiety, self-reported opioid dose and opioid and cannabis use disorder symptoms. All other outcomes will be exploratory. We will record adverse events. This study has ethical approval by the Massachusetts General Brigham Institutional Review Board (#2021P000871). Results will be published in peer-reviewed journals and presented at national conferences. NCT04827992.
Abstract Summary: Scientists are doing a study to see if using cannabis (like marijuana) can help people who have a lot of pain and take strong pain medicines called opioids. They want to see if cannabis can make people feel better, use fewer opioids, and still manage their pain well. About 250 adults who have pain all the time and take opioids will join the study. These people are interested in trying cannabis to see if it helps with their pain or lets them take less of their pain medicine. They will be split into two groups: one group will use cannabis from stores, and the other group won't use cannabis for 6 months. Everyone will also get help to learn how to use less opioids. The researchers will check if the people using cannabis take less opioids and if their pain changes. They will also look at how happy and active the people are, and if they have any problems like feeling sad or worried. The study has been approved to make sure it's safe, and the results will be shared with everyone later.

Mindfulness-Based Cognitive Therapy: A Preliminary Examination of the (Event-Related) Potential for Modifying Threat-Related Attentional Bias in Anxiety.
Mindfulness (N Y).
2022;
13(7):1719-1732.
Abstract: Mindfulness-based cognitive therapy (MBCT) can reduce anxiety and depression symptoms in adults with anxiety disorders, and changes in threat-related attentional bias may be a key mechanism driving the intervention's effects on anxiety symptoms. Event-related potentials (ERPs) can illuminate the physiological mechanism through which MBCT targets threat bias and reduces symptoms of anxiety. This preliminary study examined whether P1 ERP threat-related attentional bias markers in anxious adults change from pre- to post-MBCT delivered in-person or virtually (via Zoom) and investigated the relationship between P1 threat-related attentional bias markers and treatment response. Pre- and post-MBCT, participants with moderate to high levels of anxiety ( = 50) completed a dot-probe task with simultaneous EEG recording. Analyses focused on pre- and post-MBCT P1 amplitudes elicited by angry-neutral and happy-neutral face pair cues, probes, and reaction times in the dot-probe task and anxiety and depression symptoms. Pre- to post-MBCT, there was a significant reduction in P1-Probe amplitudes ( = .23), anxiety ( = .41) and depression ( = .80) symptoms, and reaction times ( = .10). Larger P1-Angry Cue amplitudes, indexing hypervigilance to angry faces, were associated with higher levels of anxiety both pre- and post-MBCT ( = .20). Post-MBCT, anxiety symptoms were lower in the in-person versus virtual group ( = .80). MBCT may increase processing efficiency and decreases anxiety and depression symptoms in anxious adults. However, changes in threat bias specifically were generally not supported. Replication with a comparison group is needed to clarify whether changes were MBCT-specific. NCT03571386, June 18, 2018. The online version contains supplementary material available at 10.1007/s12671-022-01910-x.
Abstract Summary: Scientists did a study to see if a special kind of therapy called Mindfulness-based Cognitive Therapy (MBCT) can help adults who feel very worried or sad. They wanted to know if this therapy changes how people pay attention to scary things, which might make them feel less worried. They had 50 adults with a lot of worry do tasks while measuring their brain activity before and after the therapy. They found that after the therapy, the adults felt less worried and sad, and their brains reacted more calmly to scary things. They also got better at the tasks. People who did the therapy face-to-face felt even less worried than those who did it online. The study suggests that this therapy can help adults feel better, but more research is needed to be sure it was the therapy that made the difference.

Abstract: Postpartum depression (PPD) is a serious mental health problem that has a prevalence rate of nearly 20% in the first three months after delivery. The purpose of this study was to evaluate the benefit of Sunnyside, an internet-based cognitive-behavioral intervention, delivered in a group format compared to the same intervention delivered individually for the prevention of PPD. 210 people between 20- and 28-weeks gestation and who scored between 5 and 14 on the PHQ-8 and who did not meet criteria for major depression were recruited online. The Inventory of Depression and Anxiety Symptoms (IDAS), the Hamilton Rating Scale for Depression (HAMD), and the depression and anxiety modules of the MINI were obtained at baseline, post-treatment, and 12-weeks postpartum. Intervention adherence was measured by site usage. Across self-report and interview measures of depression there were no significant differences in outcome between the group and the individual versions of the program. Rates of major depression and generalized anxiety disorder in the postpartum period were low and adherence to the conditions was similarly high. Participants in the individual condition were significantly more satisfied than participants in the group condition (p < 0.05). The sample was predominantly white (85%) and recruited online, which may limit generalizability. The group intervention was not more effective than the individual intervention. However, ignoring groups, many measures improved over time. The results of this study provide evidence that mood symptoms improve when participating in an online preventive intervention for postpartum depression.
Abstract Summary: Scientists did a study to see if a special online program called Sunnyside could help moms feel better and not get sad after having a baby. This sadness is called postpartum depression, and it happens to about 1 in 5 moms. They had 210 moms-to-be try Sunnyside either by themselves or with a group before their babies were born. They checked on the moms' feelings before, after, and 3 months after the program. They found that both ways helped the moms just the same, and not many moms got really sad or worried after. Moms liked doing the program by themselves a little more. Most of the moms in the study were white, so it might work differently for other moms. The study shows that doing Sunnyside can make moms feel better and might stop them from getting postpartum depression.

Abstract: Greater understanding is required of how smokers with smoking-related diseases respond to smoking cessation medications. This analysis of EAGLES data compared continuous abstinence rates (CARs) in smokers with/without smoking-related diseases and assessed participant demographic and baseline characteristics that may serve as predictors of continuous abstinence (CA). EAGLES was a 24-week (12-week treatment, 12-week follow-up), double-blind, active- (nicotine replacement therapy; patch) and placebo-controlled study in motivated-to-quit smokers with/without psychiatric disorders. This analysis assessed CARs at weeks 9-12 (CAR9-12) and 9-24 (CAR9-24) in participants with smoking-related diseases [asthma, chronic obstructive pulmonary disease (COPD), diabetes, and/or cardiovascular disease (n=1372)] versus controls without these comorbidities (n=6039). Participants received varenicline 1 mg twice daily, bupropion 150 mg twice daily, nicotine patches 21 mg/day with taper, or placebo for 12 weeks. Stepwise logistic modeling was also performed to analyze odds ratio (OR) for predictors of CA at weeks 9-12 (CA9-12) and 9-24 (CA9-24). Smokers with smoking-related diseases were older, had a longer smoking history, more quit attempts, and were more likely to have a psychiatric disorder and reside in the US versus smokers without comorbidities. Fagerström Test for Cigarette Dependence scores and treatment adherence were comparable between cohorts. Smokers with smoking-related diseases had lower CARs versus controls (CAR9-12: 20.8% vs 24.0%; CAR9-24: 13.0% vs 16.9%). Use of smoking cessation medication was the strongest predictor of CA after control for demographics, smoking characteristics, and psychiatric disorder. By treatment, OR and CI were: varenicline CA9-12 (OR=3.82; 95% CI: 3.21-4.54) and CA9-24 (OR=2.92; 95% CI: 2.40-3.54); bupropion CA9-12 (OR=2.17; 95% CI: 1.81-2.60) and CA9-24 (OR=1.99; 95% CI: 1.63-2.44); nicotine patches CA9-12 (OR=2.23; 95% CI: 1.87-2.67) and CA9-24 (OR=1.86; 95% CI: 1.52-2.28). Smokers with smoking-related diseases had lower quit rates than controls. Of the active treatments compared, varenicline was most effective in smokers with asthma, COPD, diabetes, or cardiovascular disease. NCT01456936 (https://clinicaltrials.gov/ct2/show/NCT01456936).
Abstract Summary: Scientists did a study to see how well different stop-smoking medicines work for people who smoke and have diseases caused by smoking, like asthma or heart problems. They looked at a big group of smokers, some with these health issues and some without, to see who could quit smoking and stay quit for 12 and 24 weeks. They gave them different medicines or a pretend medicine (placebo) and watched what happened.
They found that people with smoking-related diseases had a harder time staying quit compared to those without these diseases. The medicine called varenicline worked best for helping people quit, especially for those with health problems from smoking. This study helps us understand that even if quitting is tougher for these smokers, there are medicines that can really help them stop.

Isolevuglandins disrupt PU.1-mediated C1q expression and promote autoimmunity and hypertension in systemic lupus erythematosus.
JCI Insight.
2022 Jul 8;
7(13):.
Abstract: We describe a mechanism responsible for systemic lupus erythematosus (SLE). In humans with SLE and in 2 SLE murine models, there was marked enrichment of isolevuglandin-adducted proteins (isoLG adducts) in monocytes and dendritic cells. We found that antibodies formed against isoLG adducts in both SLE-prone mice and humans with SLE. In addition, isoLG ligation of the transcription factor PU.1 at a critical DNA binding site markedly reduced transcription of all C1q subunits. Treatment of SLE-prone mice with the specific isoLG scavenger 2-hydroxybenzylamine (2-HOBA) ameliorated parameters of autoimmunity, including plasma cell expansion, circulating IgG levels, and anti-dsDNA antibody titers. 2-HOBA also lowered blood pressure, attenuated renal injury, and reduced inflammatory gene expression uniquely in C1q-expressing dendritic cells. Thus, isoLG adducts play an essential role in the genesis and maintenance of systemic autoimmunity and hypertension in SLE.
Abstract Summary: Scientists studied a disease called systemic lupus erythematosus (SLE), which is when the body's immune system attacks its own tissues. They looked at special proteins in the blood cells of people and mice with SLE. They found that these proteins were changed in a way that made the body create harmful antibodies. These antibodies can cause problems in the body. The scientists also discovered that a certain substance could block these changes and help reduce the disease's bad effects, like kidney damage and high blood pressure, in mice. This research could help create new treatments for people with SLE.

A Longitudinal Study of COVID-19 Sequelae and Immunity: Baseline Findings.
Ann Intern Med.

175(7):969-979.
Abstract: A substantial proportion of persons who develop COVID-19 report persistent symptoms after acute illness. Various pathophysiologic mechanisms have been implicated in the pathogenesis of postacute sequelae of SARS-CoV-2 infection (PASC). To characterize medical sequelae and persistent symptoms after recovery from COVID-19 in a cohort of disease survivors and controls. Cohort study. (ClinicalTrials.gov: NCT04411147). National Institutes of Health Clinical Center, Bethesda, Maryland. Self-referred adults with laboratory-documented SARS-CoV-2 infection who were at least 6 weeks from symptom onset were enrolled regardless of presence of PASC. A control group comprised persons with no history of COVID-19 or serologic evidence of SARS-CoV-2 infection, recruited regardless of their current health status. Both groups were enrolled over the same period and from the same geographic area. All participants had the same evaluations regardless of presence of symptoms, including physical examination, laboratory tests and questionnaires, cognitive function testing, and cardiopulmonary evaluation. A subset also underwent exploratory immunologic and virologic evaluations. 189 persons with laboratory-documented COVID-19 (12% of whom were hospitalized during acute illness) and 120 antibody-negative control participants were enrolled. At enrollment, symptoms consistent with PASC were reported by 55% of the COVID-19 cohort and 13% of control participants. Increased risk for PASC was noted in women and those with a history of anxiety disorder. Participants with findings meeting the definition of PASC reported lower quality of life on standardized testing. Abnormal findings on physical examination and diagnostic testing were uncommon. Neutralizing antibody levels to spike protein were negative in 27% of the unvaccinated COVID-19 cohort and none of the vaccinated COVID-19 cohort. Exploratory studies found no evidence of persistent viral infection, autoimmunity, or abnormal immune activation in participants with PASC. Most participants with COVID-19 had mild to moderate acute illness that did not require hospitalization. The prevalence of reported PASC was likely overestimated in this cohort because persons with PASC may have been more motivated to enroll. The study did not capture PASC that resolved before enrollment. A high burden of persistent symptoms was observed in persons after COVID-19. Extensive diagnostic evaluation revealed no specific cause of reported symptoms in most cases. Antibody levels were highly variable after COVID-19. Division of Intramural Research, National Institute of Allergy and Infectious Diseases.
Abstract Summary: Scientists did a study to learn more about the health problems that some people have after they get better from COVID-19. They looked at a group of people who had COVID-19 and another group who never got sick with it. They checked everyone's health with physical exams, blood tests, and questions about how they felt. They found that more than half of the people who had COVID-19 still felt sick with symptoms like tiredness and trouble thinking, even after they were supposed to be better. Women and people who had anxiety before were more likely to feel this way. The study also showed that these health issues made people's lives harder. But when the scientists did more tests, they couldn't find a clear reason why these people still felt sick. They also learned that the body's defense against the virus, called antibodies, was different in people after they had COVID-19. This study helps us understand that many people still feel unwell after COVID-19, but we need to learn more about why this happens.

Poly(GR) and poly(GA) in cerebrospinal fluid as potential biomarkers for C9ORF72-ALS/FTD.
Nat Commun.
2022 May 19;
13(1):2799.
Abstract: GGGGCC repeat expansion in C9ORF72, which can be translated in both sense and antisense directions into five dipeptide repeat (DPR) proteins, including poly(GP), poly(GR), and poly(GA), is the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Here we developed sensitive assays that can detect poly(GA) and poly(GR) in the cerebrospinal fluid (CSF) of patients with C9ORF72 mutations. CSF poly(GA) and poly(GR) levels did not correlate with age at disease onset, disease duration, or rate of decline of ALS Functional Rating Scale, and the average levels of these DPR proteins were similar in symptomatic and pre-symptomatic patients with C9ORF72 mutations. However, in a patient with C9ORF72-ALS who was treated with antisense oligonucleotide (ASO) targeting the aberrant C9ORF72 transcript, CSF poly(GA) and poly(GR) levels decreased approximately 50% within 6 weeks, indicating they may serve as sensitive fluid-based biomarkers in studies directed against the production of GGGGCC repeat RNAs or DPR proteins.
Abstract Summary: Scientists are studying a genetic change that is the main cause of two brain diseases: ALS and FTD. This change makes extra bits of protein that might be linked to these diseases. The scientists made special tests to measure two types of these extra proteins in the fluid that surrounds the brain and spine. They found that the amount of these proteins didn't match up with how old people were when they got sick, how long they had been sick, or how quickly their sickness got worse. The levels were the same in people who had symptoms and those who didn't yet. But, when they treated one patient with a special medicine that targets the genetic change, the levels of these proteins went down by half in just 6 weeks. This means that measuring these proteins could help us see if treatments for these brain diseases are working.

Effect of a Novel Intervention Targeting Appetitive Traits on Body Mass Index Among Adults With Overweight or Obesity: A Randomized Clinical Trial.
JAMA Netw Open.
2022 May 2;
5(5):e2212354.
Abstract: Behavioral weight loss (BWL) programs result in weight loss for some, but most individuals regain the weight. The behavioral susceptibility theory proposes that genetically determined appetitive traits, such as food responsiveness (FR) and satiety responsiveness (SR), interact with the environment and lead to overeating and weight gain; the regulation of cues (ROC) intervention was developed specifically to target FR and SR. To evaluate the efficacy of ROC, ROC combined with BWL (ROC+), BWL, and an active comparator (AC) over 12 months of treatment and 12 months of follow-up. This randomized clinical trial was conducted from December 2015 to December 2019 in a university clinic. A total of 1488 volunteers from the community inquired about the study; 1217 were excluded or declined to participate. Eligibility criteria included body mass index (BMI) of 25 to 45, age 18 to 65 years, and lack of comorbidities or other exclusionary criteria that would interfere with participation. Data were analyzed from September 2021 to January 2022. ROC uniquely targeted FR and SR. BWL included energy restriction, increasing physical activity, and behavior therapy techniques. ROC+ combined ROC with BWL. AC included mindfulness, social support, and nutrition education. Change in body weight as measured by BMI. A total of 271 adults (mean [SD] age, 46.97 [11.80] years; 81.6% female [221 participants]; mean [SD] BMI, 34.59 [5.28]; 61.9% White [167 participants]) were assessed at baseline, midtreatment, posttreatment, and 6-month and 12-month follow-up. Sixty-six participants were randomized to AC, 69 to ROC, 67 to ROC+, and 69 to BWL. Results showed that ROC, ROC+, and BWL interventions resulted in significantly lower BMI at the end of treatment (BMI ROC, -1.18; 95% CI, -2.10 to -0.35; BMI ROC+, -1.56; 95% CI, -2.43 to -0.67; BMI BWL, -1.58; 95% CI, -2.45 to -0.71). Compared with BWL, BMI at the end of treatment was not significantly different from ROC or ROC+ (BMI ROC, 0.40; 95% CI, -0.55 to 1.36; BMI ROC+, 0.03; 95% CI, -0.88 to 0.93); however, the BMI of the AC group was substantially higher (BMI AC, 1.58; 95% CI, 0.72 to 2.45). BMI reductions at 24 months after randomization were similar for ROC, ROC+, and BWL. Importantly, FR was a moderator of treatment effects with more weight loss for participants who scored higher in FR in the ROC and ROC+ groups. These findings suggest that ROC and ROC+ provide alternative weight loss approaches for adults. These models could be particularly effective for individuals who struggle with FR and could be used as a precision approach for weight loss. ClinicalTrials.gov Identifier: NCT02516839.
Abstract Summary: Scientists did a study to see if a new program could help people lose weight and keep it off. They tested four different ways: a new program focusing on how much people want to eat and how full they feel (ROC), this new program plus a traditional weight loss program (ROC+), just the traditional program (BWL), and a different program that taught mindfulness and healthy eating (AC). They had 271 adults try these programs for a year and checked on them for another year after that.
They found that the new program (ROC), the combined program (ROC+), and the traditional program (BWL) all helped people lose weight. The different program (AC) didn't work as well. People who really wanted to eat a lot did better with the new program or the combined program. This means that the new program could be a good choice for people who have a hard time controlling how much they want to eat. The study shows that there are different ways to help people lose weight and keep it off.

Abstract: The association between hypertension and melanoma is unclear, and previous analyses of data from the ASPirin in Reducing Events in the Elderly (ASPREE) study demonstrated a reduced number of invasive melanoma events amongst aspirin-exposed hypertensive individuals. Data from the ASPREE study which included (1) the intervention period with a median follow-up of 4.7 years, and (2) the observational period with an additional 2 years follow-up, were combined for this analysis. Logistic regression analyses examined the association between baseline hypertension and treatment status and past melanoma history. Survival analyses examined the association between hypertension and melanoma risk, and the effect of aspirin across hypertension groups. Cox proportional hazards models were used to compare incidence across groups. 19,114 participants (median age of 74 years) were randomised to daily 100 mg aspirin or placebo. At baseline, hypertension and past melanoma history were recorded in 14,195 and 685 individuals, respectively. After adjustment for confounders, hypertension was significantly associated with past melanoma history (OR=1.34, 95%CI: 1.11-1.62). In a prospective analysis, baseline hypertension was not associated with melanoma risk. However, aspirin was associated with a reduced risk of incident melanoma amongst individuals with uncontrolled hypertension (blood pressure ≥140/90 mmHg; HR=0.63, 95%CI 0.44-0.89), but not in those with controlled hypertension (HR=1.04, 95%CI 0.74-1.46). Our results support a reduced melanoma incidence amongst individuals with uncontrolled hypertension exposed to aspirin. Additional studies are required to confirm these findings.
Abstract Summary: Scientists wanted to know if there's a link between high blood pressure and skin cancer called melanoma. They looked at a big study where older people either took aspirin or a fake pill every day for about 5 years, and then they kept checking on them for 2 more years. They found that people with high blood pressure were more likely to have had melanoma in the past. But high blood pressure didn't make it more likely for them to get melanoma later on. The cool part is that people with high blood pressure that wasn't under control seemed to get less melanoma if they took aspirin. This didn't happen for people whose high blood pressure was under control. The scientists think aspirin might help prevent skin cancer for some people, but they need to do more research to be sure.

Abstract: Improving treatment outcomes for smokers with major depressive disorder (MDD) can have significant public health implications. To evaluate the safety and efficacy of smoking cessation pharmacotherapy among smokers with MDD. Secondary analysis of a randomized, double-blind, active- (nicotine patch) and placebo-controlled trial of 12 weeks of either varenicline or bupropion with a 12-week follow-up. Community volunteers 18-75 years of age; smoke 10+ cigarettes/day; with clinically stable MDD (N = 2635) or no psychiatric disorder (N = 4028), from 140 sites in 16 countries. Twelve weeks of pharmacotherapy (placebo [PLA], nicotine replacement therapy [NRT], bupropion [BUP], varenicline [VAR]) plus brief cessation counseling. Primary safety outcome: the occurrence of ≥1 treatment-emergent, moderate to severe neuropsychiatric adverse event (NPSAE). Primary efficacy outcome: biochemically confirmed continuous abstinence (CA) during the final 4 weeks of treatment (Weeks 9-12). A total of 6653 participants (56% female; 39% MDD) ~47 years old. Risk of NPSAEs did not differ by medication for MDD. MDD had higher risk (p < .0001) for NPSAEs than the NPC. Efficacy (6653; intent-to-treat): CA rates for MDD versus NPC respectively were 31.2% versus 38.0% VAR; 23.0% versus 26.1% BUP; 22.6% versus 26.4% NRT; and 13.4% versus 13.7% PLA but no differential treatment effect was noted within the cohorts. All active treatments differed from PLA but VAR showed the largest effect. Results suggest that for MDD smokers, inclusive of those with recurrent episode, varenicline plus counseling may be the best pharmacological option for the treatment of smoking given its greater efficacy effect size and similar risk of NPSAEs. ClinicalTrials.gov Identifier: NCT01456936. https://clinicaltrials.gov/ct2/show/NCT01456936.
Abstract Summary: Scientists did a study to see if medicine helps people with major depression stop smoking safely. They had 6653 volunteers, some with depression and some without, try different stop-smoking medicines or a fake pill for 12 weeks. They also talked with a counselor. They checked who stopped smoking without having bad side effects. They found that the medicine varenicline worked best, especially for people with depression. It helped more people quit smoking than the other medicines or the fake pill, and it was just as safe. This means that varenicline could be a good choice for people with depression who want to stop smoking.

Abstract: Background Sodium (Na) stored in skin and muscle tissue is associated with essential hypertension. Sodium magnetic resonance imaging is a validated method of quantifying tissue stores of Na. In this study, we evaluated tissue Na in patients with elevated blood pressure or stage I hypertension in response to diuretic therapy or low Na diet. Methods and Results In a double-blinded, placebo-controlled trial, patients with systolic blood pressure 120 to 139 mm Hg were randomized to low sodium diet (<2 g of sodium), chlorthalidone, spironolactone, or placebo for 8 weeks. Muscle and skin Na using sodium magnetic resonance imaging and pulse wave velocity were assessed at the beginning and end of the study. Ninety-eight patients were enrolled to undergo baseline measurements and 54 completed randomization. Median baseline muscle and skin Na in 98 patients were 16.4 mmol/L (14.9, 18.9) and 13.1 mmol/L (11.1, 16.1), respectively. After 8 weeks, muscle Na increased in the diet and chlorthalidone arms compared with placebo. Skin sodium was decreased only in the diet arm compared with placebo. These associations remained significant after adjustment for age, sex, body mass index, systolic blood pressure, and urinary sodium. No changes were observed in pulse wave velocity among the different groups when compared with placebo. Conclusions Diuretic therapy for 8 weeks did not decrease muscle or skin sodium or improve pulse wave velocity in patients with elevated blood pressure or stage I hypertension.

Abstract Summary: Doctors wanted to see if taking water pills (diuretics) or eating less salt could lower the amount of salt in the muscles and skin of people with high blood pressure. They used a special MRI to measure the salt in the body and checked how stiff the arteries were. They had some people eat less salt, some take water pills, and some take a fake pill for 8 weeks. They found that eating less salt did lower the salt in the skin but not in the muscles, and the water pills didn't lower the salt in either place. Also, neither eating less salt nor taking water pills made the arteries less stiff. This study helps us understand that just taking water pills might not be enough to get rid of extra salt in the body for people with a little high blood pressure.

Abstract: Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disability-free survival outcome was defined as absence of dementia, persistent disability or death. Selection of potential predictors from amongst 25 biomedical, psychosocial and lifestyle variables including recognized geriatric risk factors, utilizing a machine-learning approach. Separate models were developed for men and women. The selected predictors were evaluated in a multivariable Cox proportional hazards model and validated internally by bootstrapping. We included 19,114 Australian and US participants aged ≥65 years (median 74 years, IQR 71.6-77.7). Common predictors of a worse prognosis in both sexes included higher age, lower Modified Mini-Mental State Examination score, lower gait speed, lower grip strength and abnormal (low or elevated) body mass index. Additional risk factors for men included current smoking, and abnormal eGFR. In women, diabetes and depression were additional predictors. The biased-corrected areas under the receiver operating characteristic curves for the final prognostic models at 5 years were 0.72 for men and 0.75 for women. Final models showed good calibration between the observed and predicted risks. We developed a prediction model in which age, cognitive function and gait speed were the strongest predictors of disability-free survival in healthy older people.Trial registration Clinicaltrials.gov (NCT01038583).
Abstract Summary: Scientists wanted to find out what helps older people stay healthy and active without disabilities. They looked at information from a big study where older people took aspirin to see if it helped them stay healthy. These people were already healthy when they started and didn't have heart problems, dementia, or trouble moving around.
The researchers used a special computer program to pick out important health signs from 25 different things like mood, lifestyle, and body measurements. They made different health prediction models for men and women.
They found that for both men and women, being older, having a slower walking speed, a weaker hand grip, and not having a normal body weight could mean a higher chance of getting sick or disabled. For men, smoking and having kidney problems were extra risks. For women, having diabetes or feeling very sad were extra risks.
The models they made were pretty good at guessing who would stay healthy. This study helps us understand what to look out for to help older people stay healthy for as long as possible.

Abstract: Metformin is the most commonly prescribed medication to treat diabetes. Emerging evidence suggests that metformin could have off target effects that might help promote healthy muscle aging, but these effects have not been thoroughly studied in glucose tolerant older individuals. The purpose of this study was to investigate the short-term effects of metformin consumption on skeletal muscle mitochondrial bioenergetics in healthy older adults. We obtained muscle biopsy samples from 16 healthy older adults previously naïve to metformin and treated with metformin (METF; 3F, 5M), or placebo (CON; 3F, 5M), for two weeks using a randomized and blinded study design. Samples were analyzed using high-resolution respirometry, immunofluorescence, and immunoblotting to assess muscle mitochondrial bioenergetics, satellite cell (SC) content, and associated protein markers. We found that metformin treatment did not alter maximal mitochondrial respiration rates in muscle compared to CON. In contrast, mitochondrial HO emission and production were elevated in muscle samples from METF versus CON (METF emission: 2.59 ± 0.72 SE Fold, P = 0.04; METF production: 2.29 ± 0.53 SE Fold, P = 0.02). Furthermore, the change in HO emission was positively correlated with the change in type 1 myofiber SC content and this was biased in METF participants (Pooled: R = 0.5816, P = 0.0006; METF: R = 0.674, P = 0.0125). These findings suggest that acute exposure to metformin does not impact mitochondrial respiration in aged, glucose-tolerant muscle, but rather, influences mitochondrial-free radical and SC dynamics. NCT03107884, clinicaltrials.gov.
Abstract Summary: Doctors often give a medicine called metformin to people with diabetes. Scientists think this medicine might also help older people's muscles stay healthy, but they're not sure. So, they did a study with 16 older people who had never taken metformin before. Some of them got metformin, and some got a pretend pill for two weeks. They took tiny pieces of the people's muscles to see what was happening inside. They found that metformin didn't change how the muscles use energy, but it did make the muscles produce more of a certain thing that could be both good and bad for the cells. Also, metformin seemed to be linked to a type of muscle cell that helps repair muscles. This study helps us understand that even if metformin doesn't make older muscles stronger right away, it might help keep them healthy in other ways.

Abstract: Gene dosage disorders (GDDs) constitute a major class of genetic risks for psychopathology, but there is considerable debate regarding the extent to which different GDDs induce different psychopathology profiles. The current research speaks to this debate by compiling and analyzing dimensional measures of several autism-related traits (ARTs) across seven diverse GDDs. The sample included 350 individuals with one of 7 GDDs, as well as reference idiopathic autism spectrum disorder (ASD; n = 74) and typically developing control (TD; n = 171) groups. The GDDs were: Down, Williams-Beuren, and Smith-Magenis (DS, WS, SMS) syndromes, and varying sex chromosome aneuploidies ("plusX", "plusXX", "plusY", "plusXY"). The Social Responsiveness Scale (SRS-2) was used to measure ARTs at different levels of granularity-item, subscale, and total. General linear models were used to examine ART profiles in GDDs, and machine learning was used to predict genotype from SRS-2 subscales and items. These analyses were completed with and without covariation for cognitive impairment. Twelve of all possible 21 pairwise GDD group contrasts showed significantly different ART profiles (7/21 when co-varying for IQ, all Bonferroni-corrected). Prominent GDD-ART associations in post hoc analyses included relatively preserved social motivation in WS and relatively low levels of repetitive behaviors in plusX. Machine learning revealed that GDD group could be predicted with plausible accuracy (~60-80%) even after controlling for IQ. GDD effects on ARTs are influenced by GDD subtype and ART dimension. This observation has consequences for mechanistic, clinical, and translational aspects of psychiatric neurogenetics.
Abstract Summary: This study looked at how different genetic disorders can affect the way people behave or think, especially in relation to autism. The researchers studied 350 people with one of seven different genetic disorders, and compared them to people with autism and people without any of these conditions. They used a special scale to measure different autism-related traits and used computer models to predict which genetic disorder a person might have based on these traits. They found that different disorders can lead to different behaviors, and that they could often predict the disorder based on these behaviors. This could help doctors better understand and treat these conditions.

Abstract: Opioid overdoses require a rapid response, but emergency responders are limited in how quickly they can arrive at the scene for administering naloxone. If laypersons are trained to administer naloxone and are notified of overdoses, more lives can be saved. This study aimed to examine the feasibility of the Opioid Rapid Response System (ORRS) that recruits, trains, and links citizen responders to overdose events in their community in real-time to administer naloxone. Aim of this paper is to present the protocols for recruiting participants through multiple communication channels; developing and evaluating the online training which has both interactive and asynchronous modules; randomly assigning laypersons to either online naloxone training or waitlist control group; measuring participants' knowledge, skills, and attitudes before and after the training; and distributing intranasal naloxone kits to participants for use in events of overdose in their community. Sampling: Utilizing a combination of purposive sampling methods, laypersons from across five Indiana counties who did not self-identify as current first responders were invited to participate. In this two-arm randomized waitlist-controlled study (N = 220), individuals were assigned into either online training or waitlist control that received the training two weeks later. A linear mixed model will be used for determining the changes in targeted outcomes in the training group and accommodate for fixed and random effects. While ORRS can become a community-engaged, cost-effective model for technology-based emergency response for opioid overdoses, study protocols can be useful for other emergency response programs that involve laypersons. gov Registration Number: NCT04589676.
Abstract Summary: Scientists are trying to see if regular people, like you and me, can help save lives when someone has taken too many pain medicines called opioids. Sometimes, these medicines can make a person stop breathing, and they need a special medicine called naloxone really fast to wake up again. The study is about teaching people through the internet how to give naloxone to someone who needs it. They want to know if people can learn this online and then be ready to help in their own neighborhoods.
They asked 220 people from five places in Indiana to join the study. Some people got the training right away, and others had to wait two weeks. They checked to see how much the people learned and if they felt okay about helping in an emergency. Everyone who learned got a naloxone kit to carry with them.
The big idea is that if more people know how to use naloxone, they can help save lives before the ambulance arrives. This could be a smart and cheap way to help people who overdose on opioids, and the way they're doing this study might help with other emergencies too.

Abstract: Nonrestorative sleep is commonly reported by individuals with fibromyalgia, but there is limited information on the reliability and responsiveness of self-reported sleep measures in this population. (1) Examine the reliability and validity of the Patient-Reported Outcomes Measurement Information System (PROMIS) sleep measures in women with fibromyalgia, and (2) Determine the responsiveness of the PROMIS sleep measures to a daily transcutaneous electrical nerve stimulation (TENS) intervention in women with fibromyalgia over 4 weeks compared with other measures of restorative sleep. In a double-blinded, dual-site clinical trial, 301 women with fibromyalgia were randomly assigned to utilize either Active-TENS, Placebo-TENS, or No-TENS at home. Measures were collected at baseline and after 4 weeks of treatment. To assess self-reported sleep, the participants completed three PROMIS short forms: Sleep Disturbance, Sleep-Related Impairment, Fatigue, and the Pittsburgh Sleep Quality Index (PSQI). To assess device-measured sleep, actigraphy was used to quantify total sleep time, wake after sleep onset, and sleep efficiency. Linear mixed models were used to examine the effects of treatment, time, and treatment*time interactions. The PROMIS short forms had moderate test-retest reliability (ICC 0.62 to 0.71) and high internal consistency (Cronbach's alpha 0.89 to 0.92). The PROMIS sleep measures [mean change over 4 weeks, 95% confidence interval (CI)], Sleep Disturbance: -1.9 (-3.6 to -0.3), Sleep-Related Impairment: -3 (-4.6 to -1.4), and Fatigue: -2.4 (-3.9 to -0.9) were responsive to improvement in restorative sleep and specific to the Active-TENS group but not in the Placebo-TENS [Sleep Disturbance: -1.3 (-3 to 0.3), Sleep-Related Impairment: -1.2 (-2.8 to 0.4), Fatigue: -1.1 (-2.7 to 0.9)] or No-TENS [Sleep Disturbance: -0.1 (-1.6 to 1.5), Sleep-Related Impairment: -0.2 (-1.7 to 1.4), Fatigue: -.3 (-1.8 to 1.2)] groups. The PSQI was responsive but not specific with improvement detected in both the Active-TENS: -0.9 (-1.7 to -0.1) and Placebo-TENS: -0.9 (-1.7 to 0) groups but not in the No-TENS group: -0.3 (-1.1 to 0.5). Actigraphy was not sensitive to any changes in restorative sleep with Active-TENS [Sleep Efficiency: -1 (-2.8 to 0.9), Total Sleep Time: 3.3 (-19.8 to 26.4)]. The PROMIS sleep measures are reliable, valid, and responsive to improvement in restorative sleep in women with fibromyalgia. www.ClinicalTrials.gov, identifier: NCT01888640.
Abstract Summary: Scientists did a study to see if a special kind of sleep questionnaire was good at measuring sleep problems in women with a condition called fibromyalgia, which can make your muscles and joints hurt and cause tiredness. They also wanted to know if this questionnaire could tell if a treatment using a gentle electric current (called TENS) helped these women sleep better. They had 301 women try either the real TENS, a pretend TENS, or no TENS at all for four weeks. The women answered questions about their sleep and wore a sleep tracker.
The study found that the questionnaire was good at telling if the women's sleep got better, especially for those who used the real TENS treatment. The pretend TENS and no TENS didn't show much change. The sleep tracker didn't really show if the TENS treatment helped. This means the questionnaire could be a helpful tool for doctors to understand and treat sleep problems in people with fibromyalgia.

Abstract: Blood testosterone concentrations in women decline during the reproductive years and reach a nadir in the seventh decade, after which concentrations increase and are restored to those of reproductive-aged women early in the eighth decade. We aimed to establish the association between the concentration of testosterone in the blood and risk of major adverse cardiovascular events (MACE) and all-cause mortality in healthy older women. SHOW was a prospective cohort substudy of the longitudinal randomised ASPREE trial. Eligible participants were women aged at least 70 years from Australia with unimpaired cognition, no previous MACE, and a life expectancy of at least 5 years. Participants who were receiving hormonal or steroid therapy were ineligible for inclusion. We measured serum concentrations of sex steroids with liquid chromatography-tandem mass spectrometry and of SHBG with immunoassay. We compared lower concentrations of sex hormones with higher concentrations using four quartiles. Primary endpoints were risk of MACE and all-cause mortality, the associations of which with sex steroid concentrations were assessed using Cox proportional hazards regression that included age, body-mass index, smoking status, alcohol consumption, diabetes, hypertension, dyslipidaemia, impaired renal function, and treatment allocation in the ASPREE trial (aspirin placebo). ASPREE is registered with ClinicalTrials.gov, NCT01038583. Of the 9180 women recruited to the ASPREE trial between March 10, 2010, and Dec 31 2014, 6358 participants provided sufficient biobank samples at baseline and 5535 were included in the final analysis. Median age at entry was 74·0 years (IQR 71·7-77·7). During a median 4·4 years of follow-up (24 553 person-years), 144 (2·6%) women had a first MACE (incidence 5·9 per 1000 person-years). During a median 4·6 years of follow-up (3·8-5·6), 200 women died (7·9 per 1000 person-years). In the fully adjusted models, higher concentrations of testosterone were associated with a lower incidence of MACE (quartile 4 quartile 1: hazard ratio 0·57 [95% CI 0·36-0·91]; p=0·02), as were higher concentrations of DHEA (quartile 4 quartile 1: 0·61 [0·38-0·97]; p=0·04). For oestrone, a lower risk of MACE was seen for concentrations in quartile 2 only, compared with quartile 1 (0·55 [0·33-0·92]; p=0·02). In fully adjusted models, no association was seen between SHBG and MACE, or between any hormone or SHBG and all-cause mortality. Blood concentrations of testosterone and DHEA above the lowest quartile in older women were associated with a reduced risk of a first-ever MACE. Given that the physiological effects of DHEA are mediated through its steroid metabolites, if the current findings were to be replicated, trials investigating testosterone therapy for the primary prevention of ischaemic cardiovascular disease events in older women would be warranted.

Abstract Summary: Scientists wanted to find out if there's a link between the amount of testosterone in older women's blood and their risk of heart problems or dying from any cause. They studied women over 70 who were healthy and not on hormone treatments. They measured different hormones in the women's blood and watched them for about 4.5 years to see if they had heart issues or passed away.
They found that women with higher levels of testosterone and another hormone called DHEA had fewer heart problems. But these hormone levels didn't change the chances of dying from any cause. The study suggests that having more testosterone might help prevent heart problems in older women. If more research confirms this, doctors might consider giving testosterone to older women to keep their hearts healthy.

Increased amplitude of hippocampal low frequency fluctuations in early psychosis: A two-year follow-up study.
Schizophr Res.
2022 Mar;
241:260-266.
Abstract: Neuroimaging studies have revealed hippocampal hyperactivity in schizophrenia. In the early stage of the illness, hyperactivity is present in the anterior hippocampus and is thought to spread to other regions as the illness progresses. However, there is limited evidence for changes in basal hippocampal function following the onset of psychosis. Resting state functional MRI signal amplitude may be a proxy measure for increased metabolism and disrupted oscillatory activity, both consequences of an excitation/inhibition imbalance underlying hippocampal hyperactivity. Here, we used fractional amplitude of low frequency fluctuations (fALFF) to test the hypothesis of progressive hippocampal hyperactivity in a two-year longitudinal case-control study. We found higher fALFF in the anterior and posterior hippocampus of individuals in the early stage of non-affective psychosis at study entry. Contrary to our hypothesis of progressive hippocampal dysfunction, we found evidence for normalization of fALFF over time in psychosis. Our findings support a model in which hippocampal fALFF is a marker of psychosis vulnerability or acute illness state rather than an enduring feature of the illness.
Abstract Summary: Scientists did a study to learn more about how a part of the brain called the hippocampus works differently in people with a mental illness called schizophrenia. They used a special brain scan to look at the activity in the hippocampus when the brain is at rest. They thought that in people with schizophrenia, the hippocampus becomes more active over time. They checked people with early schizophrenia and compared them with people without the illness over two years. Surprisingly, they found that the brain activity in the hippocampus of the people with schizophrenia became more normal as time went on. This means that the extra activity in the hippocampus might just happen when the illness starts or when it gets worse, not all the time. This is important because it helps us understand schizophrenia better and could help doctors figure out how to treat it.

Proof-of-Concept Feasibility Trial of a Dissonance-Based Sun Safety Intervention for Young Adult Tanners.
Ann Behav Med.

56(8):830-841.
Abstract: Melanoma is the second most common cancer in young adults. Social media may be a means to conduct interventions to increase sun safety in young adults. We conducted a randomized proof-of-concept pilot trial to evaluate the feasibility and acceptability of a dissonance-based social media intervention designed to promote sun safety in young adult tanners. Young adult tanners (N = 66) were randomized into two 4-week interventions in which participants were incentivized to create content for a social media campaign on healthy skin or healthy lifestyle. Feasibility outcomes included retention, participation, acceptability, and contamination. We also examined the impact of participation on motivation to engage in the target health behaviors and outdoor tanning intentions. Retention was 100%. Most Healthy Skin (88%) and Healthy Lifestyle participants (91%) created ≥1 post. Acceptability was high with 94% and 97% of participants in Healthy Skin and Healthy Lifestyle conditions, respectively, agreeing they would recommend the campaign to a friend. At 4 weeks, Healthy Skin participants reported greater declines in motivation to tan indoors (p = .0017) and outdoors (p = .0003), and greater increases in motivation to wear sunscreen (p = .0009) and protective clothing (p = .0342). Healthy Skin participants reported greater declines in intentions to tan outdoors in the next year (p = .0286). A dissonance-based, social media sun safety intervention was feasible and acceptable. Future research should examine the efficacy and longer-term effects of this intervention in young adults at elevated risk for skin cancer. Clinicaltrials.gov NCT03834974 https://clinicaltrials.gov/ct2/show/NCT03834974.
Abstract Summary: This study tested a new way to encourage young adults to protect their skin from the sun, using social media. The researchers asked 66 young adults who like to tan to join a 4-week program. They were split into two groups: one group posted about healthy skin habits, and the other about a healthy lifestyle. The study found that almost all participants enjoyed the program and would recommend it to a friend. The group that posted about healthy skin habits showed a bigger decrease in their desire to tan and a bigger increase in their desire to use sunscreen and wear protective clothing. This suggests that using social media could be a good way to help young adults avoid skin cancer. Future studies should look at how well this works over a longer time.

Early pharmacological interventions for universal prevention of post-traumatic stress disorder (PTSD).

2(2):CD013443.
Abstract: Post-traumatic stress disorder (PTSD) is a severe and debilitating condition. Several pharmacological interventions have been proposed with the aim to prevent or mitigate it. These interventions should balance efficacy and tolerability, given that not all individuals exposed to a traumatic event will develop PTSD. There are different possible approaches to preventing PTSD; universal prevention is aimed at individuals at risk of developing PTSD on the basis of having been exposed to a traumatic event, irrespective of whether they are showing signs of psychological difficulties. To assess the efficacy and acceptability of pharmacological interventions for universal prevention of PTSD in adults exposed to a traumatic event. We searched the Cochrane Common Mental Disorders Controlled Trial Register (CCMDCTR), CENTRAL, MEDLINE, Embase, two other databases and two trials registers (November 2020). We checked the reference lists of all included studies and relevant systematic reviews. The search was last updated on 13 November 2020. We included randomised clinical trials on adults exposed to any kind of traumatic event. We considered comparisons of any medication with placebo or with another medication. We excluded trials that investigated medications as an augmentation to psychotherapy. We used standard Cochrane methodological procedures. In a random-effects model, we analysed dichotomous data as risk ratios (RR) and number needed to treat for an additional beneficial/harmful outcome (NNTB/NNTH). We analysed continuous data as mean differences (MD) or standardised mean differences (SMD). We included 13 studies which considered eight interventions (hydrocortisone, propranolol, dexamethasone, omega-3 fatty acids, gabapentin, paroxetine, PulmoCare enteral formula, Oxepa enteral formula and 5-hydroxytryptophan) and involved 2023 participants, with a single trial contributing 1244 participants. Eight studies enrolled participants from emergency departments or trauma centres or similar settings. Participants were exposed to a range of both intentional and unintentional traumatic events. Five studies considered participants in the context of intensive care units with traumatic events consisting of severe physical illness. Our concerns about risk of bias in the included studies were mostly due to high attrition and possible selective reporting. We could meta-analyse data for two comparisons: hydrocortisone versus placebo, but limited to secondary outcomes; and propranolol versus placebo. No study compared hydrocortisone to placebo at the primary endpoint of three months after the traumatic event. The evidence on whether propranolol was more effective in reducing the severity of PTSD symptoms compared to placebo at three months after the traumatic event is inconclusive, because of serious risk of bias amongst the included studies, serious inconsistency amongst the studies' results, and very serious imprecision of the estimate of effect (SMD -0.51, 95% confidence interval (CI) -1.61 to 0.59; I = 83%; 3 studies, 86 participants; very low-certainty evidence). No study provided data on dropout rates due to side effects at three months post-traumatic event. The evidence on whether propranolol was more effective than placebo in reducing the probability of experiencing PTSD at three months after the traumatic event is inconclusive, because of serious risk of bias amongst the included studies, and very serious imprecision of the estimate of effect (RR 0.77, 95% CI 0.31 to 1.92; 3 studies, 88 participants; very low-certainty evidence). No study assessed functional disability or quality of life. Only one study compared gabapentin to placebo at the primary endpoint of three months after the traumatic event, with inconclusive evidence in terms of both PTSD severity and probability of experiencing PTSD, because of imprecision of the effect estimate, serious risk of bias and serious imprecision (very low-certainty evidence). We found no data on dropout rates due to side effects, functional disability or quality of life. For the remaining comparisons, the available data are inconclusive or missing in terms of PTSD severity reduction and dropout rates due to adverse events. No study assessed functional disability. This review provides uncertain evidence only regarding the use of hydrocortisone, propranolol, dexamethasone, omega-3 fatty acids, gabapentin, paroxetine, PulmoCare formula, Oxepa formula, or 5-hydroxytryptophan as universal PTSD prevention strategies. Future research might benefit from larger samples, better reporting of side effects and inclusion of quality of life and functioning measures.
Abstract Summary: Scientists did a big study to see if certain medicines can help stop people from getting PTSD after they go through something really scary. PTSD is when someone keeps feeling stressed and scared after the scary thing is over. The researchers looked at a lot of different medicines to see if they could help people not get PTSD. They checked out 13 studies with 2023 people in them. Some of the medicines they looked at were hydrocortisone and propranolol.
They found out that it's not clear if these medicines really help. The studies had some problems, like not enough people finished them, or the results weren't reported the right way. Also, the studies didn't agree with each other, and some didn't have enough information. They didn't even look at how these medicines might affect how people live their lives or how happy they are.
So, right now, we don't know for sure if these medicines can stop PTSD. The scientists say we need more and better studies to figure it out. They also say it's important to know if the medicines have bad side effects and if they make people's lives better.

76(8):1117-1124.
Abstract: Routine use of vitamin D supplements has increased substantially in the United States. However, the safety and tolerability of long-term use of high-dose vitamin D are not known. We assessed the safety and tolerability of high-dose, daily vitamin D in the vitamin D and type 2 diabetes (D2d) study. In total, 2423 overweight/obese persons with prediabetes were randomized in a double-blind manner to either 4000 IU of vitamin D (the tolerable upper intake level for adults by the National Academy of Medicine) taken daily or matching placebo. All participants were included in this analysis. Incident adverse events (AE) were ascertained 4 times a year at in-person visits (twice a year) and interim remote encounters (twice a year) and were defined as untoward or unfavorable medical occurrences. Serious adverse events (SAE) included death, life-threatening events, and hospitalizations. A total of 8304 AEs occurred during 3 years of follow-up and were less frequent in the vitamin D group compared to placebo (Incidence Rate Ratio [IRR] = 0.94; 95% Confidence Interval (CI) 0.90, 0.98). The overall frequency of protocol-specified AEs of interest, which included nephrolithiasis, hypercalcemia, hypercalciuria, or low estimated glomerular filtration rate, was low and did not differ by group. There were no significant between-group differences in total SAEs (IRR = 0.96 (0.81, 1.14)). Vitamin D supplementation at 4000 IU per day was safe and well tolerated among overweight/obese participants at high risk for diabetes who were appropriately monitored for safety. In this population, this dose of vitamin D did not increase risk of AEs or SAEs, including those previously associated with vitamin D such as hypercalcemia, hypercalciuria, or nephrolithiasis. ClinicalTrials.gov NCT01942694, prospectively registered September 16, 2013.
Abstract Summary: Scientists wanted to see if taking a lot of vitamin D every day is safe. They gave 2,423 people who were a bit heavy and almost had diabetes either 4,000 units of vitamin D or a fake pill that didn't do anything. They checked on these people for three years to see if they had any health problems. They found that the people taking vitamin D didn't have more health issues than those who took the fake pill. This means that taking this much vitamin D is safe for people who are a bit heavy and might get diabetes, as long as a doctor is watching over them.

Effect of Sleep Extension on Objectively Assessed Energy Intake Among Adults With Overweight in Real-life Settings: A Randomized Clinical Trial.
JAMA Intern Med.

182(4):365-374.
Abstract: Short sleep duration has been recognized as a risk factor for obesity. Whether extending sleep duration may mitigate this risk remains unknown. To determine the effects of a sleep extension intervention on objectively assessed energy intake, energy expenditure, and body weight in real-life settings among adults with overweight who habitually curtailed their sleep duration. This single-center, randomized clinical trial was conducted from November 1, 2014, to October 30, 2020. Participants were adults aged 21 to 40 years with a body mass index (calculated as weight in kilograms divided by height in meters squared) between 25.0 and 29.9 and had habitual sleep duration of less than 6.5 hours per night. Data were analyzed according to the intention-to-treat principle. After a 2-week habitual sleep period at baseline, participants were randomized to either an individualized sleep hygiene counseling session that was intended to extend their bedtime to 8.5 hours (sleep extension group) or to continue their habitual sleep (control group). All participants were instructed to continue daily routine activities at home without any prescribed diet or physical activity. The primary outcome was change in energy intake from baseline, which was objectively assessed as the sum of total energy expenditure and change in body energy stores. Total energy expenditure was measured by the doubly labeled water method. Change in body energy stores was computed using regression of daily home weights and body composition changes from dual-energy x-ray absorptiometry. Sleep duration was monitored by actigraphy. Changes from baseline were compared between the 2 groups using intention-to-treat analysis. Data from 80 randomized participants (mean [SD] age, 29.8 [5.1] years; 41 men [51.3%]) were analyzed. Sleep duration was increased by approximately 1.2 hours per night (95% CI, 1.0 to 1.4 hours; P < .001) in the sleep extension group vs the control group. The sleep extension group had a significant decrease in energy intake compared with the control group (-270 kcal/d; 95% CI, -393 to -147 kcal/d; P < .001). The change in sleep duration was inversely correlated with the change in energy intake (r = -0.41; 95% CI, -0.59 to -0.20; P < .001). No significant treatment effect in total energy expenditure was found, resulting in weight reduction in the sleep extension group vs the control group. This trial found that sleep extension reduced energy intake and resulted in a negative energy balance in real-life settings among adults with overweight who habitually curtailed their sleep duration. Improving and maintaining healthy sleep duration over longer periods could be part of obesity prevention and weight loss programs. ClinicalTrials.gov Identifier: NCT02253368.
Abstract Summary: This study looked at whether getting more sleep could help overweight adults eat less and lose weight. The researchers worked with adults who usually didn't get enough sleep. They split them into two groups: one group was taught how to get more sleep, while the other group didn't change their sleep habits. The results showed that the group who got more sleep ate less and lost weight. This suggests that getting enough sleep could be a good way to help prevent obesity and assist in weight loss.

Metronidazole treatment rapidly reduces genital inflammation through effects on bacterial vaginosis-associated bacteria rather than lactobacilli.
J Clin Invest.
2022 Mar 15;
132(6):.
Abstract: BackgroundBacterial vaginosis (BV) causes genital inflammation and increases HIV risk, whereas a vaginal microbiota dominated by Lactobacillus species is associated with immune quiescence and relative HIV protection. BV treatment reduces genital inflammation, but it is unclear whether this reduction is driven by a decrease in BV-associated bacteria or an increase in Lactobacillus species.METHODSTo evaluate the short-term effect of standard BV treatment on genital immunology and the vaginal microbiota, vaginal swabs were collected immediately before and after metronidazole treatment for BV and analyzed with multiplex ELISA, metagenomic sequencing, and quantitative PCR.RESULTSTopical metronidazole treatment rapidly reduced vaginal levels of proinflammatory cytokines, chemokines, and soluble immune markers of epithelial barrier disruption. Although the vaginal microbiota shifted to dominance by L. iners or L. jensenii, this proportional shift was primarily driven by a 2 to 4 log10-fold reduction in BV-associated bacteria absolute abundance. BV treatment induced no change in the absolute abundance of L. crispatus or L. iners and only minor (<1 log10-fold) increases in L. gasseri and L. jensenii that were not independently associated with reduced inflammation in multivariable models.CONCLUSIONThe genital immune benefits that are associated with Lactobacillus dominance after BV treatment were not directly attributable to an absolute increase in lactobacilli, but rather to the loss of BV-associated bacteria.Trial REGISTRATIONParticipants were recruited as part of a randomized controlled trial (ClinicalTrials.gov NCT02766023) from 2016 to 2019.FUNDINGCanadian Institutes of Health Research (PJT-156123) and the National Institute of Allergy and Infectious Diseases (HHSN2722013000141 and HHSN27200007).
Abstract Summary: Scientists did a study to see if treating a common infection in women's private parts, called bacterial vaginosis (BV), would make the area less inflamed and help protect against HIV. They gave women medicine and then checked to see what kind of tiny living things were in the area and how much inflammation there was. They found that the medicine made the inflammation go down a lot because it got rid of the bad bacteria that cause BV. Even though some good bacteria (called Lactobacillus) became more common, it was really the loss of the bad bacteria that helped, not just having more good bacteria. This is important because it helps doctors understand how to better treat BV and keep women healthy.

Leptin Promotes Greater Ki67 Expression in CD4(+) T Cells From Obese Compared to Lean Persons Living With HIV.
Front Immunol.
2021;
12:796898.
Abstract: While antiretroviral therapy (ART) has proven effective in suppressing viremia and disease progression among people living with human immunodeficiency virus (HIV; PLWH), suboptimal CD4 T cell reconstitution remains a major obstacle in nearly 30% of ART-treated individuals. Epidemiological studies demonstrate that obesity, or a body mass index (BMI) ≥ 30 kg/m, is positively correlated with greater CD4 T cell recovery in PLWH on ART. Leptin is a known immunomodulator that is produced in proportion to fat mass and is increased in obese individuals, including PLWH. We hypothesized that CD4 T cells from obese PLWH have increased cell proliferation and cytokine production compared to cells from lean PLWH, potentially modulated by differential effects of leptin signaling. To test this hypothesis, peripheral blood mononuclear cells from obese and lean PLWH with long-term virologic suppression on the same ART regimen were pretreated with recombinant leptin and then stimulated with anti-CD3/CD28 or PMA/ionomycin to measure Ki67 expression, leptin receptor (LepR) surface expression and cytokine production. In the absence of leptin, Ki67 expression and IL-17A production were significantly higher in CD4 T cells from obese compared to lean PLWH. However, LepR expression was significantly lower on CD4 T cells from obese compared to lean PLWH. After leptin treatment, Ki67 expression was significantly increased in CD4 T cells from obese PLWH compared to the lean participants. Leptin also increased IL-17A production in CD4 T cells from obese healthy controls. In contrast, leptin decreased IL-17A production in CD4 T cells from both obese and lean PLWH. Combined, these results demonstrate that obesity is associated with greater CD4 T cell proliferation among PLWH, and that higher circulating leptin levels in obesity may contribute to improved CD4 T reconstitution in PLWH initiating ART.
Abstract Summary: Scientists are studying why some people with HIV, who are taking medicine to control their virus, still have trouble with a part of their immune system not recovering fully. They noticed that people with HIV who are also heavier (or obese) seem to have better immune system recovery. They think a substance called leptin, which is more common in heavier people, might help the immune system cells grow and work better. To study this, they took blood from people with HIV who were either heavier or not, and added leptin to see what would happen. They found that in heavier people, leptin made their immune cells grow more and act stronger. This research suggests that leptin might be important in helping the immune system recover in people with HIV, especially if they are heavier.

Potential Effects of Elimination of the Black Race Coefficient in eGFR Calculations in the CREDENCE Trial.
Clin J Am Soc Nephrol.
2022 Mar;
17(3):361-373.
Abstract: The effect of including race in the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation on screening, recruitment, and outcomes of clinical trials is unclear. The inclusion and outcomes of participants in the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, which randomized individuals with type 2 diabetes and CKD to canagliflozin or placebo, were evaluated after calculating eGFR using the 2009 CKD-EPI creatinine equation with and without a race-specific coefficient or the 2021 CKD-EPI creatinine equation. Treatment effects were estimated using proportional hazards models and piecewise linear mixed effects models for eGFR slope. Of 4401 randomized participants, 2931 (67%) were White participants, 224 (5%) were Black participants, 877 (20%) were Asian participants, and 369 (8%) participants were other race. Among randomized participants, recalculation of screening eGFR using the 2009 equation without a race-specific coefficient had no effect on the likelihood of non-Black participants meeting inclusion criteria but would have excluded 22 (10%) randomized Black participants for eGFR<30 ml/min per 1.73 m. Recalculation with the 2021 equation would have excluded eight (4%) Black participants for low eGFR and one (0.4%) Black participant for eGFR≥90 ml/min per 1.73 m, whereas 30 (0.7%) and 300 (7%) non-Black participants would have been excluded for low and high eGFR, respectively. A high proportion (eight of 22; 36%) of end points in Black participants occurred in individuals who would have been excluded following recalculation using the race-free 2009 equation but not when recalculated with the 2021 equation (one of eight; 13%). Cardiovascular and kidney treatment effects remained consistent across eGFR categories following recalculation with either equation. Changes in estimated treatment effects on eGFR slope were modest but were qualitatively larger following recalculation using the 2021 equation. However, the effect of canagliflozin on chronic change in eGFR was attenuated by 7% among Black participants and increased 6% in non-Black participants. In the CREDENCE trial, eGFR recalculation without the race-specific coefficient had small but potentially important effects on event rates and the relative proportion of Black participants without substantially changing efficacy estimates. Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE), NCT02065791.
Abstract Summary: Scientists did a study to see if including a person's race in a kidney health test changes who gets to join a diabetes and kidney disease study and what the results are. They looked at a medicine called canagliflozin in a big study with people who have type 2 diabetes and kidney problems. They used different ways to measure how well the kidneys work, with and without considering the person's race. They found that not using race in the test would have stopped some Black people from joining the study, and these people had important health events during the study. The medicine worked well for everyone, no matter how they measured kidney health. This research helps us understand that small changes in how we test kidney health can affect who gets into studies and what we learn from them.

Abstract: Potent lifestyle interventions to increase moderate-to-vigorous physical activity are urgently needed for population-level chronic disease prevention. This trial tested the independent and joint effects of a mobile health system automating adaptive goal setting and immediate financial reinforcement for increasing daily walking among insufficiently active adults. Participants were randomized into a 2 (adaptive versus static goal setting) X 2 (immediate versus delayed financial incentive timing) condition factorial trial to increase walking. Participants (N=512 adults) were recruited between 2016 and 2018 and were 64.5% female, aged 18-60 years, 18.8% Hispanic, 6.1% African American, and 83% White. Principles of reinforcement and behavioral economics directed intervention design. Participants wore accelerometers daily (133,876 day-level observations) that remotely measured moderate-to-vigorous physical activity bout minutes of ≥3 minutes/day for 1 year. Primary outcomes were between-condition differences in (1) engaging ≥1 bout of moderate-to-vigorous physical activity on each day and (2) on days with ≥1 bout, daily total moderate-to-vigorous physical activity minutes. Mixed-effects hurdle models tested treatment group X phase (time) interactions using an intent-to-treat approach in 2021. Engaging in any ambulatory moderate-to-vigorous physical activity was greater for Adaptive than for Static Goal groups (OR=2.34, 95% CI=2.10, 2.60 vs OR=1.66, 95% CI=1.50, 1.84; p<0.001) and for Immediate than for Static Reinforcement groups (OR=2.16 95% CI=1.94, 2.40 vs OR=1.77, 95% CI=1.59, 1.97; p<0.01). The Immediate Reinforcement group increased by 16.54 moderate-to-vigorous physical activity minutes/day, whereas the Delayed Reinforcement group increased by 9.91 minutes/day (p<0.001). The combined Adaptive Goals + Immediate Reinforcement group increased by 16.52 moderate-to-vigorous physical activity minutes/day, significantly more than that of either Delayed Reinforcement group. This study offers automated and scalable-behavior change strategies for increasing walking among adults most at-risk for chronic diseases attributed to sedentary lifestyles. This study is registered at www.clinicaltrials.gov (ClinicalTrials.gov Identifier: NCT02717663).
Abstract Summary: Scientists did a study to help adults walk more because walking a lot can keep people from getting sick with long-term diseases. They used a phone app to set walking goals and gave people money right away or later when they walked enough. They had 512 grown-ups wear step-counting gadgets for a year to see how much they walked. They found that changing the walking goals to be harder or easier helped people walk more, and giving money right away helped even more. When they did both—changing goals and giving money right away—people walked the most. This study shows that using phone apps and rewards can make people walk more, which is good for their health.

Social Mobile Approaches to Reducing Weight (SMART) 2.0: protocol of a randomized controlled trial among young adults in university settings.
Trials.
2022 Jan 3;
23(1):7.
Abstract: Excess weight gain in young adulthood is associated with future weight gain and increased risk of chronic disease. Although multimodal, technology-based weight-loss interventions have the potential to promote weight loss among young adults, many interventions have limited personalization, and few have been deployed and evaluated for longer than a year. We aim to assess the effects of a highly personalized, 2-year intervention that uses popular mobile and social technologies to promote weight loss among young adults. The Social Mobile Approaches to Reducing Weight (SMART) 2.0 Study is a 24-month parallel-group randomized controlled trial that will include 642 overweight or obese participants, aged 18-35 years, from universities and community colleges in San Diego, CA. All participants receive a wearable activity tracker, connected scale, and corresponding app. Participants randomized to one intervention group receive evidence-based information about weight loss and behavior change techniques via personalized daily text messaging (i.e., SMS/MMS), posts on social media platforms, and online groups. Participants in a second intervention group receive the aforementioned elements in addition to brief, technology-mediated health coaching. Participants in the control group receive a wearable activity tracker, connected scale, and corresponding app alone. The primary outcome is objectively measured weight in kilograms over 24 months. Secondary outcomes include anthropometric measurements; physiological measures; physical activity, diet, sleep, and psychosocial measures; and engagement with intervention modalities. Outcomes are assessed at baseline and 6, 12, 18, and 24 months. Differences between the randomized groups will be analyzed using a mixed model of repeated measures and will be based on the intent-to-treat principle. We hypothesize that both SMART 2.0 intervention groups will significantly improve weight loss compared to the control group, and the group receiving health coaching will experience the greatest improvement. We further hypothesize that differences in secondary outcomes will favor the intervention groups. There is a critical need to advance understanding of the effectiveness of multimodal, technology-based weight-loss interventions that have the potential for long-term effects and widespread dissemination among young adults. Our findings should inform the implementation of low-cost and scalable interventions for weight loss and risk-reducing health behaviors. ClinicalTrials.gov NCT03907462 . Registered on April 9, 2019.
Abstract Summary: Scientists are studying a new way to help young people lose weight using technology like mobile apps and social media. They think gaining too much weight when you're young can lead to health problems later. In their study, called SMART 2.0, they have 642 young adults who are a bit heavier than they should be. These young people get special tools like a fitness tracker and an app to help them keep track of their weight.
There are three groups in the study. The first group gets daily text messages and social media posts with tips on how to lose weight. The second group gets all that plus help from a health coach through technology. The third group only gets the fitness tracker and app without the extra advice.
The researchers will check everyone's weight and health over two years to see which group does the best. They think the groups getting the extra help will lose more weight, especially the one with the health coach. This study is important because it could show a cheap and easy way for lots of young people to stay healthy by losing weight.

Abstract: Vaginal rings address a critical need for an independently initiated, long-acting HIV prevention method, but their design must be acceptable to promote uptake and adherence. Human-centered design (HCD) may help address design preference questions. In two Phase I studies of vaginal rings for HIV prevention conducted in the United States, we used qualitative interviews to assess participants' perceptions and opinions of the physical characteristics of the ring they used and of a ring's physical characteristics after comparing four ring designs presented via a visual tool. Users were found to prefer ring designs that appear easy to use, are physically comfortable, that function well, and are aesthetically pleasing. The parameters for these features varied widely. Product developers and marketers should consider marketing messages in which the target users feel this product is made to meet their needs and desires. Product developers are encouraged to design using HCD early in ring development (Clinical Trial Registration number: NCT03234400 and NCT03670355).
Abstract Summary: Scientists are working on a special ring that women can use to protect themselves from HIV. This ring is important because women can use it on their own and it works for a long time. To make sure women like and want to use the ring, researchers talked to women in the United States who tried different ring designs. They found out that women prefer rings that are easy to use, comfortable, work well, and look nice. The study suggests that the people who make these rings should think about what women want and like when they create and sell them. This way, more women might use the rings to stay healthy.

Abstract: The use of a polygenic risk score (PRS) to improve risk prediction of coronary heart disease (CHD) events has been demonstrated to have clinical utility in the general adult population. However, the prognostic value of a PRS for CHD has not been examined specifically in older populations of individuals aged ≥70 years, who comprise a distinct high-risk subgroup. The objective of this study was to evaluate the predictive value of a PRS for incident CHD events in a prospective cohort of older individuals without a history of cardiovascular events. We used data from 12 792 genotyped, healthy older individuals enrolled into the ASPREE trial (Aspirin in Reducing Events in the Elderly), a randomized double-blind placebo-controlled clinical trial investigating the effect of daily 100 mg aspirin on disability-free survival. Participants had no previous history of diagnosed atherothrombotic cardiovascular events, dementia, or persistent physical disability at enrollment. We calculated a PRS (meta-genomic risk score) consisting of 1.7 million genetic variants. The primary outcome was a composite of incident myocardial infarction or CHD death over 5 years. At baseline, the median population age was 73.9 years, and 54.9% were female. In total, 254 incident CHD events occurred. When the PRS was added to conventional risk factors, it was independently associated with CHD (hazard ratio, 1.24 [95% CI, 1.08-1.42], =0.002). The area under the curve of the conventional model was 70.53 (95% CI, 67.00-74.06), and after inclusion of the PRS increased to 71.78 (95% CI, 68.32-75.24, =0.019), demonstrating improved prediction. Reclassification was also improved, as the continuous net reclassification index after adding PRS to the conventional model was 0.25 (95% CI, 0.15-0.28). A PRS for CHD performs well in older people and improves prediction over conventional cardiovascular risk factors. Our study provides evidence that genomic risk prediction for CHD has clinical utility in individuals aged 70 years and older. Registration: URL: https://www.clinicaltrials.gov; Unique identifier: NCT01038583.
Abstract Summary: Scientists wanted to see if a special score that looks at many different genes could help predict heart disease in older people. They studied over 12,000 healthy older adults who had never had heart problems before. These adults were part of a big study that also looked at whether taking aspirin every day could help them stay healthy longer. The researchers used the gene score, which includes information from 1.7 million genetic variants, to guess who might have heart problems like a heart attack or die from heart disease in the next five years.
They found that this gene score did a good job of predicting heart disease on top of other usual risk factors like high blood pressure or cholesterol. When they added the gene score to these risk factors, they could predict heart disease even better. This means that using this gene score could help doctors figure out which older people might need more help to prevent heart disease. This is important because it could help keep older adults healthy and free from heart problems.

Abstract: Inflammation involves a delicate balance between pathogen clearance and limiting host tissue damage, and perturbations in this equilibrium promote disease. Patients suffering from autoimmune diseases, such as systemic lupus erythematosus (SLE), have higher levels of serum S100A9 protein and increased risk for infection. S100A9 is highly abundant within neutrophils and modulates antimicrobial activity in response to bacterial pathogens. We reasoned that increased serum S100A9 in SLE patients reflects accumulation of S100A9 protein in neutrophils and may indicate altered neutrophil function. In this study, we demonstrate elevated S100A9 protein within neutrophils from SLE patients, and MRL/ mice associates with lower mitochondrial superoxide, decreased suicidal neutrophil extracellular trap formation, and increased susceptibility to infection. Furthermore, increasing mitochondrial superoxide production restored the antibacterial activity of MRL/ neutrophils in response to These results demonstrate that accumulation of intracellular S100A9 associates with impaired mitochondrial homeostasis, thereby rendering SLE neutrophils inherently less bactericidal.
Abstract Summary: Scientists did a study to understand why people with a disease called lupus (SLE) get infections easily. They looked at a protein called S100A9 in the body's infection-fighting cells (neutrophils). They found that people with lupus have too much of this protein inside their neutrophils. This extra protein makes the neutrophils not work as well to kill bacteria. The study showed that by helping these cells make a certain substance (mitochondrial superoxide), they could fight bacteria better. This research is important because it could help find new ways to protect people with lupus from infections.

Abstract: The COVID-19 pandemic revealed an urgent need for rapid profiling of neutralizing antibody responses and development of antibody therapeutics. The current Food and Drug Administration-approved serological tests do not measure antibody-mediated viral neutralization, and there is a need for standardized quantitative neutralization assays. We report a high-throughput two-step profiling approach for identifying neutralizing convalescent plasma. Screening and downselection for serum antibody binding to the receptor-binding domain are followed by quantitative neutralization testing using a chimeric vesicular stomatitis virus expressing spike protein of SARS-CoV-2 in a real-time cell analysis assay. This approach enables a predictive screening process for identifying plasma units that neutralize SARS-CoV-2. To calibrate antibody neutralizing activity in serum from convalescent plasma donors, we introduce a neutralizing antibody standard reagent composed of two human antibodies that neutralize SARS-CoV strains, including SARS-CoV-2 variants of concern. Our results provide a framework for establishing a standardized assessment of antibody-based interventions against COVID-19.
Abstract Summary: Scientists wanted to find a quick way to tell if people's blood has strong antibodies that can fight off the virus that causes COVID-19. They made a new test that first checks if the antibodies can grab onto a part of the virus. If they can, they then see if the antibodies can actually stop the virus from working using a special virus in a lab test. They also made a standard way to measure how good the antibodies are by using a mix of two strong antibodies. This new test can help us figure out which blood from people who got better from COVID-19 is really good at stopping the virus and can help us make better treatments.
