RESUMO

Resistance training not only can improve or maintain muscle mass and strength, but also has favorable physiological and clinical effects on cardiovascular disease and risk factors. This scientific statement is an update of the previous (2007) American Heart Association scientific statement regarding resistance training and cardiovascular disease. Since 2007, accumulating evidence suggests resistance training is a safe and effective approach for improving cardiovascular health in adults with and without cardiovascular disease. This scientific statement summarizes the benefits of resistance training alone or in combination with aerobic training for improving traditional and nontraditional cardiovascular disease risk factors. We also address the utility of resistance training for promoting cardiovascular health in varied healthy and clinical populations. Because less than one-third of US adults report participating in the recommended 2 days per week of resistance training activities, this scientific statement provides practical strategies for the promotion and prescription of resistance training.

RESUMO

BACKGROUND: 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. METHODS/DESIGN: 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. DISCUSSION: 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.

RESUMO

BACKGROUND: The benefits of physical activity (PA), specifically exercise, among older adults in general are well known. Yet globally, there is concern regarding limited engagement in PA, increased obesity, and frailty among older people with human immunodeficiency virus related to low levels of PA. METHODS: We conducted in-depth interviews among 30 older, sedentary people with human immunodeficiency virus participating in the ongoing High-Intensity Exercise to Attenuate Limitations and Train Habits (HEALTH study, NCT04550676) between February 2021 and August 2022. A semistructured interview guide, informed by two minds theory, which frames behavior change as an intention-behavior gap between 2 neurocognitive systems, was used to elicit data from participants. Interviews explored general exercise perceptions, self-efficacy for exercise, mobile health intervention tailoring, outcome expectations, and PA goals. Thirty interviews from 33 participants were recorded and transcribed verbatim, and deductive and inductive thematic analysis were used using Dedoose. RESULTS: Physical activity was defined as maintaining daily living activities and addressing health goals. Previous experiences with PA varied among participants and were influenced by chronic illnesses, including human immunodeficiency virus; motivation; work commitments; interest; and social support. Reported barriers to PA included antiretroviral adverse effects, comorbidities, aging, and the COVID-19 pandemic. Changes in health status, body changes, and relationships were identified as benefits of PA. Conversations with healthcare providers supporting exercise goals were perceived to be important but rarely received by the participants. CONCLUSION: Understanding how older people with human immunodeficiency virus perceive PA is crucial to developing tailored strategies and structuring service delivery within the healthcare setting to promote a physically active life.

RESUMO

Middle-aged and older people living with HIV (PWH) are at higher risk for cognitive impairment and engage in lower levels of physical activity (PA) than seronegative counterparts. Research examining the association between objectively-measured PA and cognitive function in this population is scarce. This cross-sectional study examined the association between accelerometry-measured PA and cognitive functioning among 75 PWH (mean age 55.63). Light PA was the PA variable with the most consistent associations with cognition, with more minutes per week of light PA (performed in bouts of ≥ 10 min) being associated with better executive function, working memory/attention, and speed of processing performance, adjusted for age and current CD4 count. Findings suggest that although middle-aged and older PWH engage in more light than moderate-to-vigorous PA, light PA may be beneficial to cognition. Longitudinal studies are needed to understand PA dose-response associations with cognitive trajectories, cognitive domain specificity of PA effects, and underlying neural mechanisms of PA.

RESUMO

ABSTRACTThis study examined the factors associated with low muscle strength, muscle mass, and physical performance in 331 people living with HIV. Participants completed handgrip as a strength measure, appendicular skeletal muscle mass using bioimpedance analysis, and chair rise was a physical performance measure. Multivariate logistic regression was used to analyze the association between low values on these measures with sociodemographic, HIV-related factors, and comorbidities. Higher body mass index (BMI) (OR = 0.91; CI = 0.86-0.97) and higher CD4/CD8 ratio (OR = 0.38; 95% CI = 0.18-0.82) were associated with decreased likelihood of low handgrip strength. Being non-employed (OR = 2.08; 95% CI = 1.07-4.06), having hypertension (OR = 2.27; 95% CI = 1.13-4.54) and rheumatism (OR = 5.46; 95% CI = 1.68-17.74) increased the chance of low handgrip strength. Higher BMI (OR = 0.43; 95% CI = 0.34-0.56), CD4/CD8 ratio (OR = 0.29; 95% CI = 0.09-0.93), and bioimpedance phase angle (OR = 0.22; 95% CI = 0.12-0.40) were associated with decreased likelihood of low muscle mass. Lastly, having less than eight years of education (OR = 1.87; 95% CI = 1.02-3.41) and being non-employed (OR = 8.18; 95% CI = 3.09-21.61) increased the chance of low chair stand performance. In addition, higher CD4 + lymphocytes count (OR = 0.99; 95% CI = 0.99-0.99) was associated with a decreased likelihood of low chair stand performance. In conclusion, specific and non-specific HIV-related factors are associated with low handgrip strength, low muscle mass, and/or low chair stand performance.

RESUMO

The COVID-19 pandemic's impact on cardiovascular health behaviors including diet, physical activity, medication adherence, and self-care among people living with HIV (PLWH) remains unknown. Using qualitative analyses, we examined the impact of the COVID-19 pandemic on cardiovascular health behaviors among PLWH. Twenty-four PLWH were enrolled in this multisite study from September to October 2020. Individuals participated in semi-structured telephone interviews that were recorded, transcribed, and coded by 4 independent coders. Codes were adjudicated and analyzed for common themes. Participants were, on average, 59.2 years old (+/-9.4), 75% African American (n = 18) and 71% male (n = 17). The pandemic altered cardiovascular disease health behaviors. PLWH changed diet based on stay-at-home orders and food access. Alterations in physical activity included transitioning from gym and group class exercise to home-based exercise. Antiretroviral adherence was maintained, even when other health behaviors wavered, suggesting resilience in PLWH that may be harnessed to maintain other health behaviors.

RESUMO

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.

RESUMO

Qualitative rapid analysis is one of many rapid research approaches that offer a solution to the problem of time constrained health services evaluations and avoids sacrificing the richness of qualitative data that is needed for intervention design. We describe modifications to an established team-based, rapid analysis approach that we used to rapidly collect and analyze semi-structured interview data for a developmental formative evaluation of a cardiovascular disease prevention intervention. Over 18 weeks, we conducted and analyzed 35 semi-structured interviews that were conducted with patients and health care providers in the Veterans Health Administration to identify targets for adapting the intervention in preparation for a clinical trial. We identified 12 key themes describing actionable targets for intervention modification. We highlight important methodological decisions that allowed us to maintain rigor when using qualitative rapid analysis for intervention adaptation and we provide practical guidance on the resources needed to execute similar qualitative studies. We additionally reflect on the benefits and challenges of the described approach when working within a remote research team environment.ClinicalTrials.gov: NCT04545489.

RESUMO

BACKGROUND: Rheumatic heart disease (RHD) affects 41 million people worldwide, mostly in low- and middle-income countries, where it is co-endemic with human immunodeficiency virus (HIV). HIV is also a chronic inflammatory disorder associated with cardiovascular complications, yet the epidemiology of patients affected by both diseases is poorly understood. METHODS: Utilizing the Uganda National RHD Registry, we described the echocardiographic findings, clinical characteristics, medication prescription rates, and outcomes of all 73 people carrying concurrent diagnoses of HIV and RHD between 2009 and 2018. These individuals were compared to an age- and sex-matched cohort of 365 subjects with RHD only. RESULTS: The median age of the HIV-RHD group was 36 years (interquartile range [IQR] 15), and 86% were women. The HIV-RHD cohort had higher rates of prior stroke/transient ischemic attack (12% vs 5%, P = .02) than the RHD-only group, with this association persisting following multivariable adjustment (odds ratio [OR] 3.08, P = .03). Prevalence of other comorbidities, echocardiographic findings, prophylactic penicillin prescription rates, retention in clinical care, and mortality were similar between the 2 groups. CONCLUSIONS: Patients living with RHD and HIV in Uganda are a relatively young, predominantly female group. Although RHD-HIV comorbid individuals have higher rates of stroke, their similar all-cause mortality and RHD care quality metrics (such as retention in care) compared to those with RHD alone suggest rheumatic heart disease defines their clinical outcome more than HIV does. We believe this study to be one of the first reports of the epidemiologic profile and longitudinal outcomes of patients who carry diagnoses of both conditions.

RESUMO

We discuss recent evidence supporting the hypothesis that sarcopenia is an emerging health concern among people with human immunodeficiency virus (HIV) because of increasing life expectancy and HIV- and treatment-related comorbidities. We also hypothesize that combined exercise at higher intensity has a key role in managing sarcopenia in this population because it directly (increases muscle strength and stimulates hypertrophy) and indirectly (prevents mitochondrial dysfunction, oxidative stress, and persistent inflammation) counteracts sarcopenia hallmarks.

RESUMO

Predictive analytics can be used to identify people with HIV currently retained in care who are at risk for future disengagement from care, allowing for prioritization of retention interventions. We utilized machine learning methods to develop predictive models of retention in care, defined as no more than a 12 month gap between HIV care appointments in the Center for AIDS Research Network of Integrated Clinical Systems (CNICS) cohort. Data were split longitudinally into derivation and validation cohorts. We created logistic regression (LR), random forest (RF), and gradient boosted machine (XGB) models within a discrete-time survival analysis framework and compared their performance to a baseline model that included only demographics, viral suppression, and retention history. 21,267 Patients with 507,687 visits from 2007 to 2018 were included. The LR model outperformed the baseline model (AUC 0.68 [0.67-0.70] vs. 0.60 [0.59-0.62], P < 0.001). RF and XGB models had similar performance to the LR model. Top features in the LR model included retention history, age, and viral suppression.

RESUMO

Little is known about how demographic, employment and meteorological factors impact physical activity. We conducted an analysis to explore these associations from participants (N = 447) from six cities in the United States and matched their activity data with abstracted local meteorological data from National Oceanic and Atmospheric Administration (NOAA) weather reports. Participants were purposively recruited in 3-month blocks, from December 2015 to October 2017, to reflect physical activity engagement across the seasons. We calculated total physical activity (minutes/week) based on 7-day physical activity recall. Mild correlations were observed between meteorological factors and correlated with lower physical activity. Participants were least active in autumn (Median = 220 min/week) and most active in spring (Median = 375 min/week). In addition to level of education and total hours of work, maximum temperature, relative humidity, heating degree day, precipitation and sunset time together explained 17.6% of variance in total physical activity. Programs assisting in employment for PLHIV and those that promote indoor physical activity during more strenuous seasons are needed. Additional research to better understand the selection, preferences, and impact of indoor environments on physical activity is warranted.

RESUMO

People with HIV (PWH) experience a high frequency of symptoms that are associated with poor clinical outcomes. We conducted a secondary analysis of data from an observational study to examine whether diet, muscle strength, or physical activity were associated with symptoms among PWH and their HIV-uninfected peers. One-hundred ninety-one individuals (105 PWH and 86 HIV uninfected) with similar age and race were included. Symptoms were examined using the Patient-Reported Outcomes Measurement Information System (PROMIS-29) questionnaire, for which lower scores indicate higher function or fewer symptoms. The total healthy eating index score and carbohydrates, sugar sweet beverages, alcohol, and fiber consumption per day were obtained through 24-hour dietary recalls. A dynamometer was used to determine muscle strength. Steps per day were examined through 7 days of actigraphy. Linear regression analyses were used to determine the relationship between symptoms and diet, muscle strength, and steps per day. Participants were, on average, 54 years, 83% were African American, and 58% were male. In PWH, less healthy eating, fiber intake, and muscle strength were associated with poorer physical function; more steps per day were associated with fatigue; less daily carbohydrate consumption was associated with more pain. HIV-uninfected individuals demonstrated an association between fewer steps per day and poorer physical function and more pain, and less carbohydrate intake and more sleep disturbance. The relationships between diet, muscle strength, steps per day and PROMIS-29 health domains differed by HIV status.

RESUMO

CONTEXT: African American and Hispanic adults share a disproportionate burden of HIV infections in the United States but continue to experience suboptimal uptake of HIV pre-exposure prophylaxis (PrEP). Increasing PrEP accessibility in nontraditional care settings is a potential strategy to increase PrEP uptake in these high-risk groups. PrEP implementation in local health departments (LHDs) is not well characterized. OBJECTIVE: To evaluate HIV PrEP implementation for African American and Hispanic adults receiving medical care in Virginia's LHDs. DESIGN: We conducted a retrospective, mixed-methods evaluation of PrEP services implementation at LHDs completing their first PrEP program year between June 1, 2016, and June 30, 2019. Using pharmacy records, we estimated PrEP coverage and adherence using PrEP to need ratios (PnRs) and medication possession ratios (MPRs), respectively. Thematic analysis was used to identify barriers to PrEP delivery in interviews with 6 multidisciplinary LHD workers. RESULTS: Of the 433 PrEP clients receiving an emtricitabine/tenofovir disoproxil fumarate (Truvada) prescription in year 1, 52.0% self-identified as African American and 8.9% self-identified as Hispanic. PnRs were greater for White adults in 50.0% of clinics. The average MPR (0.79) was consistent with protective medication adherence levels; however, 25.0% of clients filled only one prescription in the program year. Qualitative findings suggest incompatibilities between health PrEP services delivery and community preferences for African American and Hispanic adults; however, LHDs in one health region were able to link communities of color to PrEP at similar rates as Whites. CONCLUSIONS: Incorporating a metric sensitive to racial/ethnic differences in the burden of HIV infection improved recognition of PrEP disparities; however, population-specific targets are needed to enhance use of the PnR for program evaluation. Tailoring of PrEP services to communities with the greatest local PrEP burden may be needed to optimize the effectiveness of PrEP programs in LHDs.

RESUMO

People living with HIV are at increased risk for sleep disturbances. Up to 75% of the HIV-infected individuals in the United States experience sleep disturbances of some kind. Previous studies have suggested an association between patient-reported sleep disturbances and impaired immune function. This study evaluates data obtained via sleep actigraphy to evaluate the relationship between objectively measured sleep, HIV viral load, and immune function. While this study found no relationship between objective sleep and CD4+ T- lymphocyte count, higher sleep efficiency was weakly correlated with lower HIV viral loads, τb(93) = -.165, p = .043. More research is warranted to clarify the nature of these relationships.

RESUMO

Social media tools have been touted as an approach to bring more democratic communication to health care. We conducted a multi-site cross-sectional study among persons living with HIV (PLWH) to desrcibe technology use among PLWH in the US and the association between social media use and body-mass index (BMI). Our primary predictor variable was social media use. Our primary outcome was BMI measured through height and weight. Descriptive statistics were used to describe the demographic profiles of the study participants and linear regression models were used to analyze associations between the outcome and predictor variables controlling for demographic characteristics. Study participants (N = 606) across 6 study sites in the United States were predominately 50-74 years old (67%). Thirty-three percent of study participants had a normal weight (BMI 18.5-25), 33% were overweight (BMI 25-30), and 32% were obese (BMI > 30). Participants used several social media sites with Facebook (45.6%) predominating. Social media use was associated with higher BMI in study participants (p < .001) and this effect persisted, although not as strongly, when limiting the analysis to those who only those who used Facebook (p = .03). Further consideration of social factors that can be ameliorated to improve health outcomes is timely and needed.

RESUMO

BACKGROUND: Advances in antiretroviral therapies have greatly improved the survival of people living with human immunodeficiency virus (HIV) infection (PLWH); yet, PLWH have a higher risk of cardiovascular disease than those without HIV. While numerous genetic loci have been linked to cardiometabolic risk in the general population, genetic predictors of the excessive risk in PLWH are largely unknown. METHODS: We screened for common and HIV-specific genetic variants associated with variation in lipid levels in 6284 PLWH (3095 European Americans [EA] and 3189 African Americans [AA]), from the Centers for AIDS Research Network of Integrated Clinical Systems cohort. Genetic hits found exclusively in the PLWH cohort were tested for association with other traits. We then assessed the predictive value of a series of polygenic risk scores (PRS) recapitulating the genetic burden for lipid levels, type 2 diabetes (T2D), and myocardial infarction (MI) in EA and AA PLWH. RESULTS: We confirmed the impact of previously reported lipid-related susceptibility loci in PLWH. Furthermore, we identified PLWH-specific variants in genes involved in immune cell regulation and previously linked to HIV control, body composition, smoking, and alcohol consumption. Moreover, PLWH at the top of European-based PRS for T2D distribution demonstrated a > 2-fold increased risk of T2D compared to the remaining 95% in EA PLWH but to a much lesser degree in AA. Importantly, while PRS for MI was not predictive of MI risk in AA PLWH, multiethnic PRS significantly improved risk stratification for T2D and MI. CONCLUSIONS: Our findings suggest that genetic loci involved in the regulation of the immune system and predisposition to risky behaviors contribute to dyslipidemia in the presence of HIV infection. Moreover, we demonstrate the utility of the European-based and multiethnic PRS for stratification of PLWH at a high risk of cardiometabolic diseases who may benefit from preventive therapies.

RESUMO

Depressive symptoms may differ in severity and change over time in people living with HIV (PLWH). Describing depression trajectories and associated clinical characteristics of PLWH in an interventional study may help in developing a more personalized medicine approach. Using latent class growth analysis four, 15-month self-reported depression trajectories were identified in 416 PLWH participating in a collaborative care program. The four subgroups were characterized by improving (58.4% [of participants]), worsening (9.4%), highly responsive (19.5%) and persistently severe (12.7%) depressive symptoms. A high proportion of individuals were in trajectories marked by improvement. Further, the highly responsive group had on average, over 50% reduction of self-reported depressive symptoms. Self-reported trauma, posttraumatic stress disorder, lower neighborhood-level education and fewer HIV and psychiatry clinic visits were associated with worsening or persistently severe depressive symptom trajectories. Members of the persistently severe group were less likely to be virally suppressed after 12-months. Identifying subgroups of PLWH based on changes in self-reported depressive symptoms may further inform intervention approaches that can advance care.

RESUMO

The aim of this study was to evaluate the effects of 16 weeks of combined exercise training (CET) on muscle strength, body composition, depression, anxiety and quality of life of people living with HIV (PLHIV). Twenty-three participants completed the study, 14 in trained group (TG) and 9 in control group (CG). TG consisted of resistance and aerobic training three times a week, while the CG was exposed to recreational activities twice a week. CET promoted increased muscle strength (25% in overall strength) and aerobic capacity (+ 20% in training speed and + 23% in VO2 during aerobic training; p < 0.05). In addition, TG had better quality of life and reduced depression rates (from 7 subjects with mild, moderate or severe depression to 1 post-training). In conclusion, this pilot data demonstrated that 16 weeks of CET increased muscle strength, and improved depression and quality of life indexes in a small sample of PLHIV.

RESUMO

Fatigue and depressive symptoms are prevalent and associated with poor clinical outcomes, though the underlying physiological mechanisms of fatigue and depression are poorly understood. We examined the impact of cardiorespiratory fitness (CRF) on fatigue and depressive symptoms in one-hundred and nine PLHIV. CRF was examined by maximal cardiorespiratory stress test and determined by peak oxygen uptake. Patient-reported fatigue was examined utilizing the HIV-Related Fatigue Scale. Depressive symptoms were examined with the Beck Depression Inventory and PROMISE 29. Data was collected at baseline and six months. Generalized estimating equations were used to determine the effect of CRF on fatigue and depressive symptoms over time. Participants were approximately 53 years old, 86% African American (n = 93), and 65% male (n = 70). After controlling for age and sex, fatigue was inversely associated with CRF (ß = -0.163; p = .005). Depressive symptoms were not associated with CRF as measured by the BeckDepression Inventory (p = .587) nor PROMIS 29 (p = .290), but over time, depressive symptoms decreased (p = .051). Increased CRF was associated with decreased fatigue levels, but was not associated with depressive symptoms. These results should guide future research aimed at how CRF might inform interventions to improve fatigue in PLHIV.
