Understanding the potential implementation determinants of Our Plan: a couples-based digital human immunodeficiency virus prevention intervention for same-gender male couples.

Background: There has been a proliferation of digital health interventions (DHIs) focused on addressing human immunodeficiency virus (HIV) prevention and treatment outcomes, including couples-based interventions with same-gender male couples. However, the barriers and facilitators of implementing couples-based HIV and sexually transmitted infection (STI) prevention interventions using digital platforms in community-based organizations remains largely unknown. The goal of this study was to explore the implementation determinants of Our Plan, a couples-based DHI designed for new relationships of same-gender male couples and dyadic, sexual partnerships. Methods: Qualitative interviews were conducted with 40 organization leaders, healthcare providers, and staff at acquired immunodeficiency syndrome (AIDS)-service and community-based organizations in 13 states serving populations in Ending the HIV Epidemic jurisdictions. Interview items and follow-up questions were guided by the Consolidated Framework for Implementation Research (CFIR) to inquire about implementation determinants of Our Plan. Results: Most participants highlighted several relative advantages of Our Plan: increasing capacity to support couples, potential synergy with existing programs, and opportunities to increase patient engagement. Participants also discussed relative disadvantages: misalignment with organizational values in the provision of patient-centered models of care and low interest from some priority populations. Participants emphasized the need for adaptability of Our Plan to fit within their local contexts, which encompassed support for both implementers and end-users, cultural tailoring, and privacy and security features. The desired evidence needed to implement Our Plan focused on data on impact, acceptability, and usability and functionality from communities most heavily impacted by the HIV epidemic. The majority of participants described how Our Plan could be integrated within service delivery and aligned with their organization's aspirational values; however, some noted that their organizational culture valued in-person interactions, particularly among patients experiencing structural vulnerabilities. Finally, participants discussed how the implementation of Our Plan would require additional training and funding for staff to support end-users and a relationship with the developers so that they could demonstrate their investment in the communities that their organizations served. Conclusions: Our Plan was deemed a promising tool among potential implementers. To ensure optimal implementation and organizational fit, Our Plan refinement and evaluation must include implementers and end-users most impacted by the HIV epidemic throughout the entire process.

Spatial Clustering of County-Level COVID-19 Rates in the U.S.

Despite the widespread prevalence of cases associated with the coronavirus disease 2019 (COVID-19) pandemic, little is known about the spatial clustering of COVID-19 in the United States. Data on COVID-19 cases were used to identify U.S. counties that have both high and low COVID-19 incident proportions and clusters. Our results suggest that there are a variety of sociodemographic variables that are associated with the severity of COVID-19 county-level incident proportions. As the pandemic evolved, communities of color were disproportionately impacted. Subsequently, it shifted from communities of color and metropolitan areas to rural areas in the U.S. Our final period showed limited differences in county characteristics, suggesting that COVID-19 infections were more widespread. The findings might address the systemic barriers and health disparities that may result in high incident proportions of COVID-19 clusters.

Factors Associated With HIV Testing Among Atlanta's Homeless Youth.

Homeless youth experience increased risk of contracting HIV, making HIV testing imperative in this population. We analyzed factors associated with HIV testing among homeless youth in Atlanta, Georgia using data from the 2015 Atlanta Youth Count and Needs Assessment. The analysis included 693 homeless youth aged 14-25 years, of whom 88.4% reported ever being tested for HIV, and 74.6% reported being tested within the previous year. Prevalence of ever testing for HIV was significantly higher among youth who reported risk factors for HIV (sexually active, transactional sex, or ever having an STI). Higher prevalence of testing within the last year was significantly associated with experiencing physical abuse or transactional sex. However, reporting ≥ 4 sexual partners or not using condoms were not associated with higher testing. Although testing prevalence among homeless youth was high, homeless youth engaging in certain high risk behaviors could benefit from further promotion of HIV testing.

Voluntary exercise increases resilience to social defeat stress in Syrian hamsters.

Exposure to social stressors can cause profound changes in an individual's well-being and can be an underlying factor in the etiology of a variety of psychopathologies, such as post-traumatic stress disorder (PTSD). In Syrian hamsters, a single social defeat experience results in behavioral changes collectively known as conditioned defeat (CD), and includes an abolishment of territorial aggression and the emergence of high levels of defensive behaviors. In contrast, voluntary exercise has been shown to promote stress resilience and can also have anxiolytic-like effects. Although several studies have investigated the resilience-inducing effects of voluntary exercise after exposure to physical stressors, such as restraint and electric shock, few studies have examined whether exercise can impart resilience in response to ethologically-based stressors, such as social defeat. In Experiment 1, we tested the hypothesis that voluntary exercise can have anxiolytic-like effects in socially defeated hamsters. In the elevated plus maze, the exercise group exhibited a significant reduction in risk assessment, a commonly used index of anxiety, compared to the no-exercise group. In the open-field test, animals in the exercise group exhibited a significant reduction in locomotor behavior and rearing, also an indication of an anxiolytic-like effect of exercise. In Experiment 2, we examined whether exercise can reverse the defeat-induced potentiation of defensive behaviors using the CD model. Socially defeated hamsters in the exercise group exhibited significantly lower levels of defensive/submissive behaviors compared to the no-exercise group upon exposure to the resident aggressor. Taken together, these results are among the first to suggest that voluntary exercise may promote resilience to social defeat stress in Syrian hamsters.
