RESUMEN

BACKGROUND: The HIV research workforce is not representative of populations most affected by the epidemic. Innovative educational programs are needed to motivate diverse student populations to pursue careers in HIV research. METHODS: The Duke University Center for AIDS Research Evidence2Practice (E2P) program is a 3-day interactive workshop that introduces students from Historically Black Colleges and Universities (HBCU) to HIV pre-exposure prophylaxis, implementation science, and human-centered design. Participants develop 1-page action plans to increase awareness and uptake of pre-exposure prophylaxis on their campus. The program was evaluated using a partially mixed-method concurrent equal status study design with pre-program and post-program surveys and in-depth interviews. RESULTS: Among the 52 participating students, 44 completed the preworkshop survey, 45 completed the postworkshop survey, and 10 participated in an in-depth interview. Most participants identified as Black or African American and cisgender female. Participating in the E2P program was associated with: (1) an increase in median interest in pursuing a career in HIV research (P < 0.01) and (2) a decrease in median perceived difficulty in starting a career in HIV research (P < 0.01). Several students described that a lack of knowledge about initiating an HIV research career, a perceived lack of qualifications and knowledge about HIV science, and limited experience were major barriers to considering careers in HIV research. CONCLUSIONS: The E2P program enhanced HBCU students' interest in careers related to HIV research and improved their self-efficacy to pursue such careers. On-campus educational enrichment initiatives, led by active HIV researchers and clinicians, should be a critical part of diversifying the HIV workforce.

RESUMEN

The Great American Biotic Interchange (GABI) was a key biogeographic event in the history of the Americas. The rising of the Panamanian land bridge ended the isolation of South America and ushered in a period of dispersal, mass extinction, and new community assemblages, which sparked competition, adaptation, and speciation. Diversification across many bird groups, and the elevational zonation of others, ties back to events triggered by the GABI. But the exact timing of these events is still being revealed, with recent studies suggesting a much earlier time window for faunal exchange, perhaps as early as 20 million years ago (Mya). Using a time-calibrated phylogenetic tree, we show that the jay genus Cyanolyca is emblematic of bird dispersal trends, with an early, pre-land bridge dispersal from Mesoamerica to South America 6.3-7.3 Mya, followed by a back-colonization of C. cucullata to Mesoamerica 2.3-4.8 Mya, likely after the land bridge was complete. As Cyanolyca species came into contact in Mesoamerica, they avoided competition due to a prior shift to lower elevation in the ancestor of C. cucullata. This shift allowed C. cucullata to integrate itself into the Mesoamerican highland avifauna, which our time-calibrated phylogeny suggests was already populated by higher-elevation, congeneric dwarf-jays (C. argentigula, C. pumilo, C. mirabilis, and C. nanus). The outcome of these events and fortuitous elevational zonation was that C. cucullata could continue colonizing new highland areas farther north during the Pleistocene. Resultingly, four C. cucullata lineages became isolated in allopatric, highland regions from Panama to Mexico, diverging in genetics, morphology, plumage, and vocalizations. At least two of these lineages are best described as species (C. mitrata and C. cucullata). Continued study will further document the influence of the GABI and help clarify how dispersal and vicariance shaped modern-day species assemblages in the Americas.

RESUMEN

Counterfeit medications infiltrate drug supply chains at various entry points. While scientific advancements continue to deter counterfeit medications, these imitation therapies still manage to circumvent national and international regulations to reach unsuspecting consumers. Certain manufacturers of human immunodeficiency virus (HIV) prevention and treatment medications within the United States recently encountered counterfeit versions of their therapies that in some instances contained antipsychotic and pain reliever products. People on HIV treatment or those taking HIV prevention therapies who consume counterfeit medications are at risk of having their HIV management strategies compromised or seroconverting from an HIV negative to an HIV positive status, respectively. The implicated manufacturers reportedly took legal actions against the discovered counterfeiters, alerted impacted pharmacies, and assisted them with removal of illegitimate drugs. However, communities' gradual awareness or lack thereof in regards to counterfeit HIV prevention and treatment medications is likely to result in speculation about how many consumers took real versus fake medications, contributing to consumer distrust. This commentary provides details of a stakeholder meeting that took place with one of the leading manufacturers of HIV treatment and prevention medications to query its responses to counterfeit medications identified among its available product supplies in pharmacies. This manuscript also recommends to manufacturers ways to augment their communication strategies to communities if similar medicinal breaches occurred in the future.

RESUMEN

Introduction: HIV PrEP (pre-exposure prophylaxis) is underutilized among Latinx and Black men who have sex with men (MSM) in the United States. Although peer navigation approaches may increase PrEP uptake and adherence, it remains unclear what strategies work best for MSM of color. Methods: From July 2017 to August 2018, we conducted semi-structured in-depth interviews with 25 purposively sampled Latinx and Black cisgender MSM to evaluate how the intersectionality of race/ethnicity, sexual orientation, and other identities influenced men's views on PrEP in general and on peer navigation specifically. Thematic analysis was used to identify and analyze emergent themes. Results: Emergent themes included: (1) awareness of vulnerability in intimate relationships; (2) barriers to PrEP initiation including perceived side effects, stigma, and financial concerns; (3) a wish to connect with other Latinx and Black MSM in a health and prevention space; and (4) the desire for peer matching based on identity considerations and lived experience. Younger men and Spanish-speaking Latinx men were most interested in peer navigation to access PrEP, while bisexual men had confidentiality concerns. Conclusions: In our study, Latinx and Black MSM viewed peer navigation services favorably, especially if they addressed men's desire to connect with other MSM of color. Policy Implications: Developing culturally-congruent peer navigation programming could help improve PrEP uptake and care engagement for Latinx and Black MSM. Programs should recruit peers from the racial/ethnic minority communities most impacted by HIV and prioritize matching peers to clients based on identity concerns, needs, and preferences.

RESUMEN

The dynamics of static and traveling breathers in two-species Bose-Einstein condensates in a one-dimensional optical lattice is modelled within the tight-binding approximation. Two coupled discrete nonlinear Schrödinger equations describe the interaction of the condensates in two cases of relevance: a mixture of two ytterbium isotopes and a mixture of (87)Rb and (41)K. Depending on their initial separation, interaction between static breathers of different species can lead to the formation of symbiotic structures and transform one of the breathers from a static into a traveling one. Collisions between traveling and static discrete breathers composed of different species are separated into four distinct regimes ranging from totally elastic when the interspecies interaction is highly attractive to mutual destruction when the interaction is sufficiently large and repulsive. We provide an explanation of the collision features in terms of the interspecies coupling and the negative effective mass of the discrete breathers.

RESUMEN

BACKGROUND: Community engagement has been a cornerstone of National Institute of Allergy and Infectious Diseases (NIAID)'s HIV/AIDS clinical trials programs since 1990. Stakeholders now consider this critical to success, hence the impetus to develop evaluation approaches. OBJECTIVES: The purpose was to assess the extent to which community advisory boards (CABs) at HIV/AIDS trials sites are being integrated into research activities. METHODS: CABs and research staff (RS) at NIAID research sites were surveyed for how each viewed (a) the frequency of activities indicative of community involvement, (b) the means for identifying, prioritizing, and supporting CAB needs, and (c) mission and operational challenges. RESULTS: Overall, CABs and RS share similar views about the frequency of community involvement activities. Cluster analysis reveals three groups of sites based on activity frequency ratings, including a group notable for CAB-RS discordance. CONCLUSIONS: Assessing differences between community and researcher perceptions about the frequency of and challenges posed by specific engagement activities may prove useful in developing evaluation tools for assessing community engagement in collaborative research settings.

RESUMEN

BACKGROUND: African American accrual to prevention trials at rates representative of the disease burden experienced by this population requires additional resources and focused efforts. PURPOSE: To describe the rationale, context, and criteria for selection of sites that received Minority Recruitment Enhancement Grants (MREGs) to increase African American recruitment to the Selenium and Vitamin E Cancer Prevention Trial (SELECT). To determine if African American accrual was higher among the 15 MREG sites when compared with similar nonawarded sites. METHODS: Changes in African American accrual at sites that received MREGs are compared with changes in a group of 15, frequency-matched, nonawarded sites using a quasi-experimental, post hoc analysis. Successful and unsuccessful recruitment strategies reported by the MREG sites are described. RESULTS: The increased number of African American participants accrued per month at MREG sites post-funding was higher than the change at comparison sites by a factor of 3.38 (p = 0.004, 95% CI: 1.51-7.57). An estimated 602 additional African American participants were recruited at MREG sites due to MREG funding, contributing to the overall 14.9% African American recruitment. Successful recruitment strategies most reported by MREG sites included increasing staff, transportation resources, recruiting through the media, mailings, and prostate cancer screening clinics during off-hours. LIMITATIONS: Comparison sites were chosen retrospectively, not by randomization. Although comparison sites were selected to be similar to MREG sites with regard to potential confounding factors, it is possible that unknown factors could have biased results. Cost-effective analyses were not conducted. CONCLUSIONS: MREG sites increased African American accrual in the post-funding period more than comparison sites, indicating MREG funding enhanced the sites' abilities to accrue African American participants. Targeted grants early in the accrual period may be a useful multi-site intervention to increase African American accrual for a prevention study where adequate African American representation is essential.

RESUMEN

BACKGROUND: Previous large chemoprevention studies have not recruited significant numbers of minorities. The Selenium and Vitamin E Cancer Prevention Trial (SELECT) is a large phase III study evaluating the impact of selenium and vitamin E on the clinical incidence of prostate cancer. Over 400 SELECT study sites in the USA, Canada, and Puerto Rico recruited men to this trial. The SELECT recruitment goal was 24% minorities, with 20% black, 3% Hispanic, and 1% Asian participants. The goal for black participants was set at 20% because of their proportion in the United States population and their prevalence of prostate cancer. METHODS: The minority recruitment strategies in SELECT were to: 1) consider minority recruitment during site selection; 2) expand the eligibility criteria by lowering the age criterion for black men and including men with controlled co-morbid illnesses; 3) develop a national infrastructure; 4) give additional funds to sites with the potential to increase black enrollment; and 5) provide resources to maximize free media opportunities to promote SELECT. RESULTS: SELECT recruitment began in August 2001 and was intended to last five years, but concluded two years ahead of schedule in June 2004. Of the 35 534 participants enrolled, 21% were minorities, with 15% black, 5% Hispanic, and 1% Asian. CONCLUSIONS: Careful planning, recruitment of large numbers of clinical centers and adequate resources accomplished by the combined efforts of the National Cancer Institute (NCI), Southwest Oncology Group (SWOG), SELECT Recruitment and Adherence Committee (RAC), SELECT Minority and Medically Underserved Subcommittee (MMUS), and the local SELECT sites resulted in attainment of the estimated sample size ahead of schedule and recruitment of the largest percentage of black participants ever randomized to a cancer prevention trial.
