People with HIV are at increased risk of cardiovascular events; thus, care delivery strategies that increase access to comprehensive cardiovascular disease (CVD) risk management are a priority. We report the results of a multi-component telemedicine-based strategy to improve blood pressure control among people with HIV-Assess and Adapt to the Impact of COVID-19 on CVD Self-Management and Prevention Care in Adults Living with HIV (AAIM-High). The AAIM High strategy is a virtual adaptation of our previously published EXTRA-CVD strategy and consisted of hypertension education and six components: nurse-led care coordination (delivered by teleconference or telephone), home systolic blood pressure (SBP) monitoring, evidence-based treatment algorithms, electronic health records tools, technology coach, and communication preferences assessment. People with HIV (n = 74) with comorbid hypertension at three academic medical centers were enrolled in a single arm implementation study from January 2021 to December 2022. Over 12 months, the average patient-performed home SBP decreased by 7.7 mmHg (95% CI -11.5, -3.9). The percentage of patients at treatment goal, defined as average SBP <130 mmHg, increased from 46.0% to 72.5% at 12 months. By adapting to the growing use of telemedicine in healthcare delivery, our study effectively improved hypertension control in people with HIV through a virtual, nurse-led intervention.

Wildfires continue to increase in size, intensity, and duration. There is growing evidence that wildfire smoke adversely impacts clinical outcomes; however, few studies have assessed the impact of wildfires on household air quality and subclinical cardiovascular health indicators. We measured continuous indoor and outdoor fine particulate matter (PM_2.5) concentrations from July-October 2022 at 20 residences in the rural, mountainous state of Montana in the United States. We used a combination of satellite-derived smoke plume data from the National Oceanic and Atmospheric Administration's Hazard Mapping System and household-level daily mean PM_2.5 concentrations to classify wildfire-impacted days. One participant from each household self-reported in-home blood pressure (BP) on weekly electronic surveys. We used linear mixed-effects regression models to assess associations between air pollution exposures (PM_2.5 concentrations; number of wildfire-impacted days) and systolic BP (SBP) and diastolic BP (DBP). Models were adjusted for potential time-variant confounders including temperature, humidity, and self-reported exercise. Compared to survey periods with 0 wildfire days, SBP was 3.83 mmHg higher (95% Confidence Interval [95% CI]: 0.22, 7.44) and DBP was 2.36 mmHg higher (95% CI: -0.06, 4.78) during periods with 4+ wildfire days. Across the entire study period, a 10 µg m^-3 increase in indoor PM_2.5 was associated with 1.34 mmHg higher SBP (95%CI: 0.39, 2.29) and 0.71 mmHg higher DBP (95% CI: 0.07, 1.35). We observed that wildfire-impacted days and increasing household-level PM_2.5 concentrations are associated with higher in-home BP. Our results support growing literature which indicates that wildfires adversely impact subclinical cardiovascular health. Clinical and public health messaging should emphasize the cardiovascular health impacts of wildfire smoke and educate on exposure-reduction strategies such as indoor air filtration.

BACKGROUND:Advances in antiretroviral therapy have enabled people living with HIV (PLHIV) to live longer and healthier lives. However, aging with HIV infection is accompanied by an increased risk of non-communicable diseases (NCDs), highlighting the need to integrate care services. The Academic Model Providing Access to Healthcare (AMPATH) in Eldoret, Kenyahas, which has been providing care for PLHIV for over 30 years, is seeing an increase in NCDs, particularly hypertension and diabetes, especially among older patients. It is unclear how healthcare providers manage the complex healthcare needs of older adults living with HIV (OALWH) and comorbid NCDs, or how they perceive the integration of hypertension and diabetes care within the HIV care platform. METHODS:We conducted in-depth interviews at an AMPATH facility in Eldoret, Kenya. Ten healthcare providers (three nurses and seven clinical officers) were interviewed to explore the facilitators and barriers to integrating HIV and NCD care services for OALWH. Audio records were transcribed verbatim, content analysis was performed, and the capabilities (C), opportunities (O), and motivation (M) models for behavior change (COM-B model) were used to comprehensively map the drivers and barriers that shape healthcare providers' acceptance, adoption, and implementation of integrated HIV and NCD care services. RESULTS:The majority of participants had worked for more than five years, offering care for people living with HIV. All participants had experience managing older adults living with HIV and expressed challenges with the lack of coordinated care delivery for HIV and NCDs. The participants highlighted the potential challenges of optimal adherence to antiretroviral therapy (ART) among OALWH in the presence of multiple chronic conditions. Based on these challenges, participants perceived the integration of hypertension and diabetes care into the HIV care platform as beneficial to clients and the overall healthcare system. Factors such as the availability of physical resources and infrastructure (C), availability of training opportunities for NCD care (O), leadership support (M), and motivation to provide person-centered care (M) were perceived as facilitators of HIV/NCD integrated care delivery. Impeding factors such as lack of guidelines for integration (O), siloed healthcare service delivery (O), inadequate resource allocation for NCDs (O), and perceived increased workload (M) were also highlighted by healthcare providers. CONCLUSION/CONCLUSIONS:The findings of this study highlight healthcare providers' perceived facilitators and barriers to the integration of NCD care into HIV care platforms. The insights gained from this study hold the potential to inform tailored interventions, policy decisions, and capacity-building initiatives aimed at fostering successful integration and improving overall health care delivery to meet the needs of OALWH in resource-constrained settings.

The impact of COVID-19-related mental health effects on health behaviors among people living with HIV (PLWH) remains unknown. Our qualitative study explored the relationship between the mental health consequences of the COVID-19 pandemic and self-management of HIV and cardiovascular disease (CVD) among PLWH in the United States. Twenty-four PLWH enrolled in a multicenter, cardiovascular, clinical trial completed one-on-one semistructured interviews to assess changes in mood, health behaviors, and comorbid CVD management during the COVID-19 pandemic. The majority of participants (ages 43-70 years) were male (n = 17, 70.8%) and Black (n = 19, 79.2%). Participants reported increased mental distress during the COVID-19 pandemic, which they perceived to negatively affect heart-healthy behaviors. Despite mental health stressors, this population continued to adhere to medications, including antiretroviral therapy. Future initiatives should focus on improving mental health outcomes and promotion of healthy lifestyle choices among PLWH to mitigate adverse CVD outcomes.

BACKGROUND/UNASSIGNED:Systematic screening individuals with non-invasive devices may improve diagnosis of atrial fibrillation (AF) and reduce adverse clinical events. We systematically reviewed the existing literature to determine the yield of new AF diagnosis associated with systematic AF screening, the relative increase in yield of new AF diagnosis with systematic screening compared to usual care, and the effect of systematic AF screening on clinical outcomes compared with usual care. METHODS/UNASSIGNED:The Medline, Embase, Web of Science and Cochrane Library databases were searched from inception through 1st February 2025 for prospective cohort studies or randomised clinical trials (RCTs) of systematic AF screening with the outcome of incidence of previously undiagnosed AF from screening. Incidence rates (IR) and relative risks were calculated and random effects meta-analysis performed to synthesise rates of AF in prospective cohort studies and RCTs, as well as outcomes in RCTs. FINDINGS/UNASSIGNED:From 3806 unique records we included 32 studies representing 735,542 participants from 8 RCTs and 24 prospective cohorts. The diagnosis rate for incident AF in prospective cohorts was 2.75% (95% CI 1.87-3.62), and the pooled relative risk in RCTs was 2.22 (95% CI 1.41-3.50). The use of age and NT-proBNP (IR 4.36%, 95% CI 3.77-5.08) or AF risk score classification (4.79%, 95% CI 3.62-6.29) led to higher new AF diagnosis yields than age alone (0.93%, 95% CI 0.28-2.99). Pooled data from RCTs did not demonstrate an effect of screening on death (RR 1.01, 95% CI 0.97-1.05), cardiovascular hospitalisation (1.00, 95% CI 0.97-1.03), stroke (0.95, 95% CI 0.87-1.04) or bleeding (1.08, 95% CI 0.91-1.29). INTERPRETATION/UNASSIGNED:Systematic screening for AF using non-invasive devices is associated with increased diagnosis of AF, but not reduced adverse clinical events. Screening studies of AF utilising alternative risk stratifications and outcome measures are required.

BACKGROUND:While a growing body of scientific literature suggests that evidence-based interventions may improve health outcomes in diverse settings, little is known about the best strategies for large-scale implementation. In Africa, music-an important positive social determinant of health-leverages existing cultural values, which may effectively enhance the reach, uptake, and long-term sustainability of evidence-based interventions in the region. To understand how music interventions work, why they are effective, and with whom they resonate, this systematic review aims to evaluate the quality and empirical application of music as an implementation strategy for adopting evidence-based interventions in Africa using the RE-AIM framework as a guide. METHODS:A comprehensive librarian-assisted search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five major electronic databases, EBSCOhost, PubMed, Web of Science, Embase, and MEDLINE, were searched for empirical studies focused on using music as an implementation strategy to improve health outcomes in Africa. Two independent investigators extracted components of retrieved papers using the RE-AIM framework as a guide. RESULTS:From 981 citations, eight studies met the inclusion criteria, each reporting a unique music intervention. The interventions were conducted in West Africa (n = 3), South African regions (n = 4), and East Africa (n = 1) and included seven observational studies and one randomized controlled trial (RCT). Using the RE-AIM scoring criteria, we summarize the RE-AIM dimensions reported from selected studies - Adoption (72.5%) being the highest, followed by Reach (62.5%), Implementation (41.7%), and Efficacy/Effectiveness (20.0%). All eight studies (100%) described the intervention location, the expertise of delivery agents, the target population, and the participant characteristics. Moreover, our analysis highlighted the effectiveness of music interventions in enhancing health outcomes, particularly in improving knowledge and awareness (62.5%), facilitating behavioral change (50%), and promoting mental health (25%). CONCLUSION/CONCLUSIONS:Music interventions adapted to the sociocultural context in Africa have the potential to help prevent diseases, improve well-being, and enhance health outcomes. Our review emphasizes the importance of customizing music-based interventions to fit the cultural context, which can enhance the programs' effectiveness, acceptance, and sustainability. Clinical trials are necessary to confirm the efficacy of music interventions in specific medical conditions and from a public health promotion perspective.

Brain health is pivotal to achieving overall health and all current sustainable development goals (SDGs). However, a dedicated training program in brain health research to unravel its complex determinants, especially genetic, sociodemographic and lifestyle factors is lacking in Africa. The Growing Data-science Research in Africa to Stimulate Progress (GRASP) is a three-year program designed to harness innovation potential to build sustainable data science (DS) research capacity among qualified African scholars through innovative partnerships and collaborations. This is aimed at promoting a learning environment for boosting knowledge, managing expectations, building support systems, and overcoming environmental barriers to create a sustainable system that will inspire innovative thinking for a remarkable transformation for producing Brain Health solutions for African and the world. Highlight of GRASP is its focus on improving the DS skills of selected scholars to explore sociodemographic determinants, dietary and lifestyle factors affecting brain health and cardiovascular risks, integrating sociodemographic data with cognitive, genomics, climate and geographical data. Ten African scholars from a cross-national/multidisciplinary postgraduate clinicians and researchers pool were selected during the 2024 cycle. Activities lined up during this program comprises of a nine-month Postgraduate Certificate program that includes six months virtual training activities, a compulsory 6-week residency at the University of Ibadan (UI), Nigeria (exclusive for five outstanding performing scholars), networking sessions at scientific meetings, annual mentor-mentee communication and research project. GRASP complements these attributes with the Master of Science in Clinical Research (MSCR) degree including competencies for the clinical and translational research workforce. GRASP scholars are assessed with periodic monitoring within three years after program completion based on academic positions and publications; funding for investigator-initiated research projects or career development awards. Building DS research capacity among African scholars via the GRASP program will re-orient current understanding and inspire creative solutions in Africa's approach to combating NCDs.

BACKGROUND/UNASSIGNED:A lack of disease-related consensus measures for type 2 diabetes interventions is a barrier to comparing interventions across various contexts, as well as to implementation and scale-up. This study aimed to use an expert consensus approach to select disease-related measures for type 2 diabetes to facilitate cross-contextual research, as well as the implementation and scaling-up of initiatives. METHODS/UNASSIGNED:The study was conducted using a two-phased cross-sectional design consisting of an online survey among research experts in 17 diabetes projects working in a global context, followed by an online modified Delphi panel comprised of reviewers with domain-specific expertise from different income settings who were not survey participants. RESULTS/UNASSIGNED:Out of 153 measures from 11 domains assessed, 49 were classified as core, 58 as optional, and 46 were excluded. The domains and measures spanned several categories, including demographics, medical history, medication adherence, health behaviors, anthropometric measures, biochemical measures, and quality-of-life-related issues. CONCLUSION/UNASSIGNED:The core dataset of selected measures in type 2 diabetes may provide a standardized approach for determining which data should be collected. This can facilitate transnational comparisons between or within implementation projects to advance global diabetes research.

INTRODUCTION/BACKGROUND:The relationship between food insecurity and access to healthcare in low-resource settings remains unclear. Some studies find that food insecurity is a barrier to accessing care, while others report that food insecurity is associated with a greater need for care, leading to more care utilisation. We use data from the Harambee study in western Kenya to assess the association between food insecurity and difficulty accessing care among people living with HIV (PLWH) with or without comorbid non-communicable diseases (NCDs). METHODS:The Harambee study is a cluster randomised trial that tested the effectiveness of delivering integrated HIV and NCD care for PLWH. In this cross-sectional analysis, we examined baseline data from Harambee participants to investigate the relationship between household food insecurity and difficulty accessing care, using multivariable logistic regression models, controlling for sociodemographic factors and care satisfaction. We tested for effect measure modification by gender and household wealth and stratified analyses by NCD status. RESULTS:Among 1039 participants, 11.1% reported difficulty accessing care, and 18.9% and 51.9% of participants had moderate and severe food insecurity, respectively. Among those with difficulty accessing care, 73.9% cited transportation issues as the major barrier. Difficulty accessing care was greater with higher levels of food insecurity: among participants with low, moderate and severe food insecurity, 5.9%, 9.7% and 14.4% reported difficulty accessing care, respectively. After adjusting for confounders, severe food insecurity was independently associated with difficulty accessing care (adjusted OR=2.5, 95% CI 1.4 to 4.4). There was no statistical evidence for effect measure modification by gender or wealth. CONCLUSIONS:We found that greater food insecurity was associated with greater difficulty accessing care among PLWH with or without NCDs in rural western Kenya. These findings suggest that addressing social determinants of health may be necessary when implementing integrated HIV and NCD care programmes.

Policy engagement is an essential component of implementation research for scaling up interventions targeting non-communicable diseases (NCDs). It refers to the many ways that research team members, implementers and policymakers, who represent government decision-making, connect and interact to explore common interests. Well-conducted engagement activities foster co-production, local contextualization and assist in the successful translation of research evidence into policy and practice. We aimed to identify the challenges and facilitators to policy engagement during the early implementation phase of scale-up research studies. This qualitative study was focused on the research projects that were funded through the Global Alliance for Chronic Diseases in the 2019 round. Nineteen project teams opted to participate, with these studies implemented in 20 countries. Forty-three semi-structured stakeholder interviews, representing research, implementation and government were undertaken between August 2020 and July 2021. Transcripts were open-coded using thematic analysis to extract 63 codes which generated 15 themes reflecting both challenges and facilitators to undertaking policy engagement. Knowledge of the local government structures and trusting relationships provided the foundation for successful engagement and were strengthened by the research. Four cross-cutting concepts for engagement were identified and included: (1) the importance of understanding the policy landscape; (2) facilitating a network of suitable policy champions, (3) providing an environment for policy leaders to genuinely contribute to co-creation and (4) promoting two-way learning during researcher-policymaker engagement. We recommend undertaking formative policy analysis to gain a strategic understanding of the policy landscape and develop targeted engagement plans. Through engagement, researchers must facilitate cohesive vision and build a team of policy champions to advocate NCD research within their networks and spheres of influence. Ensuring equitable partnerships is essential for enabling local ownership and leadership. Further, engagement efforts must create a synergistic policymaker-researcher lens to promote the uptake of evidence into policy.
