We reviewed 25 randomized clinical trials that assessed the effect of peer-based interventions on health-related behaviors in adults. Effect sizes were calculated as odds ratios or standardized mean differences. We grouped most of the studies by 7 measured outcomes, with effect sizes ranging from −0.50 to 2.86. We found that peer-based interventions facilitated important changes in health-related behaviors, including physical activity, smoking, and condom use, with a small- to medium-sized effect. However, the evidence was mixed, possibly because of the heterogeneity we found in methods, dose, and other variables between the studies. Interventions aimed at increasing breastfeeding, medication adherence, women's health screening, and participation in general activities did not produce significant changes.

People living with HIV (PLHIV) experience greater loss of muscle mass and function than people without HIV. However, HIV is not routinely recognized as a sarcopenia risk factor outside of HIV literature. The purposes of this study were to establish the prevalence and predictors of sarcopenia among PLHIV, and to compare the prevalence of sarcopenia among PLHIV and people without HIV. A systematic literature search of the PubMed, Embase, Cinahl, and Scielo databases was performed following PRISMA and MOOSE guidelines. Identified articles were included if they evaluated sarcopenia among PLHIV using either the presence of low muscle mass only or low muscle mass in association with low muscle function. The pooled prevalence of sarcopenia among PLHIV and the odds ratio for sarcopenia in PLHIV compared with controls were calculated. From 13 studies and 2267 participants, the prevalence of sarcopenia among PLHIV was 24.1% (95% CI = 17.8–31.0%). PLHIV presented 6.1 greater odds (95% CI = 1.1–33.5) of sarcopenia compared with people without HIV, matched by age, sex, BMI, and ethnicity. Longer exposure to specific HIV drugs, tobacco and alcohol, lower education and employment rates, and greater HIV duration were associated with sarcopenia. In conclusion, PLHIV had a high prevalence of sarcopenia, related to both HIV and non-HIV risk factors. HIV should be considered a risk factor for sarcopenia in the general population.

Introduction Peripheral artery disease (PAD) disproportionately burdens Black Americans, particularly Black men. Despite the significant prevalence and high rate of associated morbidity and mortality, awareness of and treatment initiation for PAD remains low in this demographic group. Given the well-established social cohesion among barbershops frequently attended by Black men, barbershops may be ideal settings for health screening and education to improve awareness, early detection, and treatment initiation of PAD among Black men. Methods A qualitative study involving 1:1 participant interviews in Cleveland, Ohio assessed perspectives of Black men about barbershop-based screening and education about PAD. Inductive thematic analysis was performed to derive themes directly from the data to reflect perceived PAD awareness and acceptability of screening in a barbershop setting. Results Twenty-eight African American/Black, non-Hispanic men completed a qualitative interview for this analysis. Mean age was 59.3 ± 11.2 years and 93% of participants resided in socioeconomically disadvantaged zip codes. Several themes emerged indicating increased awareness of PAD and acceptability of barbershop-based screenings for PAD, advocacy for systemic changes to improve the health of the community, and a desire among participants to increase knowledge about cardiovascular disease. Conclusions Participants were overwhelmingly accepting of PAD screenings and reported increased awareness of PAD and propensity to seek healthcare due to engagement in the study. Participants provided insight into barriers and facilitators of health and healthcare-seeking behavior, as well as into the community and the barbershop as an institution. Additional research is needed to explore the perspectives of additional stakeholders and to translate community-based screenings into treatment initiation.

Rheumatic heart disease (RHD) is a leading cause of premature mortality in low- and middle-income countries (LMICs). Women of reproductive age are a unique and vulnerable group of RHD patients, due to increased risk of cardiovascular complications and death during pregnancy. Yet, less than 5% of women of childbearing age with RHD in LMICs use contraceptives, and one in five pregnant women with RHD take warfarin despite known teratogenicity. It is unclear whether this suboptimal contraception and anticoagulant use during pregnancy is due to lack of health system resources, limited health literacy, or social pressure to bear children. We conducted a mixed methods study of 75 women living with RHD in Uganda. Questionnaires were administered to 50 patients. Transcripts from three focus groups with 25 participants were analyzed using qualitative description methodology. Several themes emerged from the focus groups, including pregnancy as a calculated risk; misconceptions about side-effects of contraceptives and anticoagulation; reproductive decision-making control by male partners, in-laws, or physicians; abandonment of patients by male partners; and considerable stigma against heart disease patients for both their reproductive and financial limitations (often worse than that directed against HIV patients). All questionnaire respondents were told by physicians that their hearts were not strong enough to support a pregnancy. Only 14% used contraception while taking warfarin. All participants felt that society would look poorly on a woman who cannot have children due to a heart condition. To our knowledge, this is the first qualitative study of female RHD patients and their attitudes toward cardiovascular disorders and reproduction. Our results suggest that health programs targeting heart disease in LMICs must pay special attention to the needs of women of childbearing age. There are opportunities for improved family/societal education programs and community engagement, leading to better outcomes and patient empowerment.

Rheumatic Heart Disease (RHD) persists as a major cardiovascular driver of mortality and morbidity among young people in low-and middle-income countries. Secondary antibiotic prophylaxis (SAP) with penicillin remains the cornerstone of RHD control, however, suboptimal treatment adherence undermines most secondary prevention programs. Many of the barriers to optimal SAP adherence are specific to the intramuscular form of penicillin and may potentially be overcome by use of oral penicillin. This noninferiority trial is comparing the efficacy of intramuscular to oral penicillin SAP to prevent progression of mild RHD at 2 years. The Intramuscular vs Enteral Penicillin Prophylaxis to Prevent Progression of Rheumatic Heart Disease (GOALIE) trial is randomizing Ugandan children aged 5 to 17 years identified by echocardiographic screening with mild RHD (Stage A or B as defined by 2023 World Heart Federation criteria) to Benzathine Benzyl Penicillin G (BPG arm, every-28-day intramuscular penicillin) or Phenoxymethyl Penicillin (Pen V arm, twice daily oral penicillin) for a period of 2 years. A blinded echocardiography adjudication panel of 3 RHD experts and 2 cardiologists is determining the echocardiographic stage of RHD at enrollment and will do the same at study completion by consensus review. Treatment adherence and study retention are supported through peer support groups and case management strategies. The primary outcome is the proportion of children in the Pen V arm who progress to more advanced RHD compared to those in the BPG arm. Secondary outcomes are patient-reported outcomes (treatment acceptance, satisfaction, and health related quality of life), costs, and cost-effectiveness of oral compared to intramuscular penicillin prophylaxis for RHD. A total sample size of 1,004 participants will provide 90% power to demonstrate noninferiority using a margin of 4% with allowance for 7% loss to follow-up. Participant enrollment commenced in October 2023 and final participant follow-up is expected in December 2026. The graphical abstract (Fig. 1) summarizes the flow of echocardiographic screening, participant enrollment and follow-up. The GOALIE trial is critical in global efforts to refine a pragmatic approach to secondary prevention for RHD control. GOALIE insists that the inferiority of oral penicillin be proven contemporarily and against the most important near-term clinical outcome of progression of RHD severity. This work also considers other factors that could influence the adoption of oral prophylaxis and change the calculus for acceptable efficacy including patient-reported outcomes and costs.

Symptom distress remains a challenging aspect of living with HIV. Physical activity is a promising symptom management strategy, but its effect on symptom distress has not been examined in a large, longitudinal HIV-infected cohort. We hypothesized that higher physical activity intensity would be associated with reduced symptom distress. We included 5370 people living with HIV (PLHIV) who completed patient-reported assessments of symptom distress, physical activity, alcohol and substance use, and HIV medication adherence between 2005 and 2016. The most frequent and burdensome symptoms were fatigue (reported by 56%), insomnia (50%), pain (46%), sadness (45%), and anxiety (45%), with women experiencing more symptoms and more burdensome symptoms than men. After adjusting for age, sex, race, time, HIV medication adherence, alcohol and substance use, site, and HIV RNA, greater physical activity intensity was associated with lower symptom intensity. Although individual symptoms may be a barrier to physical activity (e.g. pain), the consistent association between symptoms with physical activity suggests that more intense physical activity could mitigate symptoms experienced by PLHIV.

Fatigue is a subjective overwhelming feeling of tiredness at rest, exhaustion with activity, lack of energy that impedes daily tasks, lack of endurance, or a loss of vigor. Individuals with end stage renal disease (ESRD) experience a high rate and severity of fatigue. Symptom management of fatigue in this population is critical, since fatigue has been linked with lower quality of life and higher mortality rates. In this article, we present a definition and overview of fatigue, a review of factors contributing to fatigue, and ways to manage fatigue in individuals with ESRD.

The prevalence is expected to grow considerably in the next few decades as the world population grows older and societies become more industrialized. [...]these two conditions may be confused with each other. Condition Recommended Operational Definition Parameters and Stages Sarcopenia Revised consensus from the European Working Group on Sarcopenia in Older People (Cruz-Jentoft et al., 2019) Probable sarcopenia = low muscle strength Sarcopenia = low muscle strength and low muscle mass Severe sarcopenia = low muscle strength, low muscle mass, and low physical performance Frailty Fried Frailty Phenotype (Fried et al., 2001) Criteria assessed are weight loss, exhaustion, low physical activity, slowness, and weakness Not frail = no criteria are present Pre-frail = 1 to 2 criteria are present Frail = ≥3 criteria are present Resource Source URL Sarcopenia screening SARC-F https://pubmed.ncbi.nlm.nih.gov/23810110/ Frailty screening eFrailty https://efrailty.hsl.harvard.edu/ Physical activity recommendations Centers for Disease Control and Prevention https://www.cdc.gov/physical-activity-basics/guidelines/older-adults.html Department of Health and Human Services https://health.gov/our-work/nutrition-physicalactivity/physical-activity-guidelines Diet recommendations National Institute on Aging https://www.nia.nih.gov/health/healthy-eatingnutrition-and-diet World Health Organization https://www.who.int/news-room/fact-sheets/detail/healthy-diet Additional Practical Recommendations Physical Activity (Piercy et al., 2018) Adults should move more and sit less throughout the day. Current diet recommendations for adults aged ≥60 years include: (a) protein intake between 1.2 and 2.0 grams of protein per kilogram of body weight per day; (b) consumption of high-protein foods, such as fish, lean meats, poultry, nuts, lentils, and soy products; (c) making nutrient-rich foods, such as fruits, vegetables, whole grains, legumes, and low- or non-fat dairy, the basis of one's diet; (d) limiting foods high in saturated fat, sugar, and sodium; and (e) eating a variety of foods from each food group (Baum et al., 2016; Yeung et al., 2021). In summary, although identifying and treating sarcopenia and frailty is not yet a standard practice in primary care, early detection is crucial as it allows for implementing interventions that can slow the progression, improve quality of life, and reduce health care costs.

Digital ELISA-based assays for blood biomarkers of neurological disease are on the verge of clinical use. Here, we aimed to determine whether different preanalytical blood processing techniques influence results. Concentrations of neurofilament light chain (NfL), Tau and amyloid beta (Aβ) were measured in human plasma and serum specimens using digital ELISA and compared between blood products. Measured levels of NfL were highly equivalant between serum and plasma in all analyses, however, measured levels of Tau and Aβ were consistently lower in serum relative to plasma. Tau and Aβ are likely lost during clotting in serum preparations, and should be assayed in plasma to get an accurate measure of circulating levels.

People with HIV (PWH) are at increased risk for metabolic disorders affecting body mass index (BMI), chronic symptoms, and impaired physical function and capacity. Although physical activity improves health and well-being, PWH often do not meet activity recommendations necessary to achieve these benefits. Despite the known impact of symptoms, physical activity, and physical function on health, little is known about the relationships and interactions between these variables and BMI and maximum oxygen consumption during exercise (VO 2 max) in a multinational population of PWH. We examined the relationship of BMI with PROMIS-29 measures, physical activity, strength, flexibility, and VO 2 max in a diverse sample of PWH. Additionally, we examined the relationship of VO 2 max with PROMIS-29 measures. Data from 810 PWH who participated in a cross-sectional study conducted by the International Nursing Network for HIV Research (Study VII) were analyzed. Participants were recruited from 8 sites across the United States, Thailand, and South Africa. BMI was calculated from collected height and weight data. Physical function and symptoms were assessed using the PROMIS-29 measure. Physical activity was assessed using the 7-day Physical Activity Recall. VO 2 max was calculated using sex at birth, age, BMI and the 6-minute Walk Test. Data were analyzed using descriptive, correlational, and regression statistical analyses. Participants had an average age of 49.1 (± 11.1) years, 44% were female, and the average BMI of the sample group was 27 kg/m2 (± 6.7). Increased BMI was associated with decreased 6-minute Walk Test (β=-2.18, p  < 0.001), flexibility (β=-0.279, p  < 0.001), and VO 2 max (β=-0.598, p  < 0.001), even after controlling for covariates (age, sex at birth, country, years living with HIV, and antiretroviral therapy status). BMI was not associated with self-reported physical activity. Increased VO 2 max was associated with increased physical function (β = 0.069, p  < 0.001), and decreased pain (β=-0.047, p  < 0.006), even after controlling for covariates (country, years living with HIV, and antiretroviral therapy status). Future research should explore development of effective and sustainable symptom self-management interventions in PWH accounting for the potential impact of BMI and VO 2 max.
