BACKGROUND:Black men are underrepresented in hypertension trials, even though this population has higher prevalence and more adverse sequelae from hypertension, compared to other groups. In this article we present recruitment and community engagement strategies for the Community-to-Clinic Linkage Implementation Program (CLIP), a cluster-randomized trial on hypertension prevention among Black men. METHODS:Using a 2-stage recruitment process: 1) we enrolled Black-owned barbershops from zip-codes with high hypertension prevalence; and 2) recruited Black male participants who fulfilled the eligibility criteria and were customers of the barbershops. Barbershop and participant recruitment was conducted by a partner community-based organization. RESULTS:The study met the recruitment goals for barbershop enrollment (N=22) and individual participants. Of eligible individuals (N=461), 430 enrolled in the study (93% consent rate, exceeding the original enrollment goal of N=420 participants). Throughout recruitment, the study team conducted 101 unique engagements (41 prior to recruitment, 60 during recruitment), totaling engagement with180 partners across all events, including individual and group meetings, attendance at community events, and educational presentations. In addition to a primary partner community organization, the study team collaborated with a Community Advisory Council, comprised of residents, and civic and community leaders, and with the local health department and varied other organizations. CONCLUSIONS:In CLIP, a high number of academic-community engagement encounters and close collaboration with community partners contributed to successful recruitment of Black men at risk for hypertension and with adverse social determinants. Our experience may serve as to inform investigators focused on recruiting underserved populations in hypertension research trials.

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.

INTRODUCTION/BACKGROUND:Delayed Emergency Medical Services (EMS) response and transport (time from injury occurrence to hospital arrival) are associated with increased injury mortality. Inequities in accessing EMS care for injured patients are not well characterized. We sought to evaluate the association between the area deprivation index (ADI), a measure of geographic socioeconomic disadvantage, and timely access to EMS care within the United States. METHODS:The Homeland Infrastructure Foundation Level Data open-source database from the National Geospatial Intelligence Agency was used to evaluate the location of EMS stations across the United States using longitude and latitude coordinates. The ADI was obtained from Neighborhood Atlas at the census block group level. An ambulance desert (AD) was defined as populated census block groups with a geographic center outside of a 25-minute ambulance service area. The total population (urban and rural) located within an AD and outside an AD (non-ambulance desert [NAD]) and the ADI index distribution within those areas were calculated with their statistical significance derived from χ2 testing. Spearman correlations between the number of EMS stations available within 25-minutes service areas and ADI were calculated, and statistical significance was derived after accounting for spatial autocorrelation. RESULTS:A total of 42,472 ground EMS stations were identified. Of the 333,036,755 people (current US population), 2.6% are located within an AD. When stratified by type of population, 0.3% of people within urban populations and 8.9% of people within rural populations were located within an AD (p < 0.01). When compared with NADs, ADs were more likely to have a higher ADI (ADIAD, 53.13; ADINAD, 50.41; p < 0.01). The number of EMS stations available per capita was negatively correlated with ADI (rs = -0.25, p < 0.01), indicating that people living in more disadvantaged neighborhoods are likely to have fewer EMS stations available. CONCLUSION/CONCLUSIONS:Ambulance deserts are more likely to affect rural versus urban populations and are associated with higher ADIs. The impact of inequities in access to EMS care on outcomes deserves further study. LEVEL OF EVIDENCE/METHODS:Prognostic and Epidemiological; Level III.

UNLABELLED:Adolescents and young adults (AYAs) participatory approaches for HIV control have increased across LMICs, but there are few trials to evaluate effectiveness. We assessed a crowdsourced HIV self-testing (HIVST) intervention among a cohort of AYA in Nigeria. METHODS:We conducted a pragmatic stepped-wedge cluster randomized control trial recruiting participants (aged 14-24 years) from 32 local government areas across four geo-political zones in Nigeria. Eligible AYA were HIV negative or unknown HIV status, residing in study sites, spoke English, and consented. Areas were randomly assigned to one of four steps and AYA were followed for 24 months. AYA research facilitators implemented a 4YBY crowdsourced HIV prevention bundle. The primary outcome was self-reported HIVST uptake. We compared the probability of HIVST between the control and intervention periods using a generalized linear mixed model. We examined the fixed cost and per capita cost of the intervention. The protocol was registered with Clinical Trials.gov on January 15, 2021, under registration NCT04710784. RESULTS:2652 AYA were screened, and 1500 were enrolled in the study (March 10, 2021- August 31, 2023). 1333/1500 (89 %) were followed up at 24 months. The mean age of AYA was 20 ± 2.65 years old, most were students (1155/1500, 77 %), and unemployed (915/1500, 61 %). The intervention led to a 9.96-fold increase in HIV self-testing uptake compared to the control period (95 % CI: 8.36-11.85, p < 0.0001). The annual fixed cost of the intervention was estimated at US$42,237, with a per capita testing cost of US$14.8. No significant adverse events were reported. CONCLUSION/CONCLUSIONS:A crowdsourced HIV prevention intervention increased HIVST uptake among Nigerian AYA. Greater participation of AYA in the design and implementation of clinical trials is needed to achieve UNAIDS targets.

BACKGROUND:Sustaining evidence-based interventions in resource-limited settings is critical to optimizing gains in health outcomes. In 2015, we published a review of the sustainability of health interventions in African countries, highlighting gaps in the measurement and conceptualization of sustainability in the region. This review updates and expands upon the original review to account for developments in the past decade and recommendations for promoting sustainability. METHODS:First, we searched five databases (PubMed, SCOPUS, Web of Science, Global Health, and Cumulated Index to Nursing and Allied Health Literature (CINAHL)) for studies published between 2015 and 2022. We repeated the search in 2023 and 2024. The review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Studies were included if they reported on the sustainability of health interventions implemented in African countries. Study findings were summarized using descriptive statistics and narrative synthesis, and sustainability strategies were categorized based on the Expert Recommendations for Implementing Change (ERIC) strategies. RESULTS:Thirty-four publications with 22 distinct interventions were included in the review. Twelve African countries were represented in this review, with Nigeria (n = 6) having the most representation of available studies examining sustainability. Compared to the 2016 review, a similar proportion of studies clearly defined sustainability (52% in the current review versus 51% in the 2015 review). Eight unique strategies to foster sustainability emerged, namely: a) multi-sectorial partnership and developing stakeholder relationships, b) tailoring strategies to enhance program fit and integration, c) active stakeholder engagement and collaboration, d) capacity building through training, e) accessing new funding, f) adaptation, g) co-creation of intervention and implementation strategies and h) providing infrastructural support. The most prevalent facilitators of sustainability were related to micro-level factors (e.g., intervention fit and community engagement). In contrast, salient barriers were related to structural-level factors (e.g., limited financial resources). CONCLUSIONS:This review highlights some progress in the published reports on the sustainability of evidence-based intervention in Africa. The review emphasizes the importance of innovation in strategies to foster funding determinants for sustainable interventions. In addition, it underscores the need for developing contextually relevant sustainability frameworks that emphasize these salient determinants of sustainability in the region.

Hypertension is a leading preventable and controllable risk factor for cardiovascular and cerebrovascular diseases and the leading preventable risk for death globally. With a prevalence of nearly 50% and 93% of cases uncontrolled, very little progress has been made in detecting, treating, and controlling hypertension in Africa over the past thirty years. We propose the African Control of Hypertension through Innovative Epidemiology and a Vibrant Ecosystem (ACHIEVE) to implement the HEARTS package for improved surveillance, prevention, treatment/acute care of hypertension, and rehabilitation of those with hypertension complications across the life course. The ecosystem will apply the principles of an iterative implementation cycle by developing and deploying pragmatic solutions through the contextualization of interventions tailored to navigate barriers and enhance facilitators to deliver maximum impact through effective communication and active participation of all stakeholders in the implementation environment. Ten key strategic actions are proposed for implementation to reduce the burden of hypertension in Africa.

BACKGROUND/UNASSIGNED:Elevated perceived stress is associated with adverse outcomes following myocardial infarction (MI) and may account for poorer recovery among women vs men. OBJECTIVES/UNASSIGNED:This randomized controlled trial tested effects of a mindfulness-based intervention on stress levels among women with MI. METHODS/UNASSIGNED:Women with elevated stress (Perceived Stress Scale [PSS-4]≥6) at least 2 months after MI were enrolled from 12 hospitals in the United States and Canada and via community advertising. Participants were randomized to a remotely delivered mindfulness intervention (MBCT-Brief) or heart disease education, both 8 weeks long. Follow-up was 6 months. Changes in stress (PSS-10; primary outcome) and secondary outcomes (depressive symptoms, anxiety, quality of life, disease-specific health status, actigraphy-assessed sleep) were compared between groups. RESULTS/UNASSIGNED: = 0.036). CONCLUSIONS/UNASSIGNED:MBCT-Brief was associated with greater 6-month reductions in stress than an active control among adherent participants. More frequent mindfulness practice was associated with greater improvements in psychological outcomes. Strategies to engage women with MI in mindfulness training and support regular home practice may enhance these effects.
