Estimating the cost of and willingness to pay for providing the dapivirine ring for HIV prevention in Kenya
This analysis revealed that costs are predominantly driven by commodities. Attempts to further reduce the cost of the commodities could significantly reduce the overall cost of PrEP ring service. Approximately half the women were willing to pay up to US$2 per month for the PrEP ring. Since the demand for the PrEP ring appears to be higher among current oral PrEP users compared to non-users, women who have initiated oral PrEP but who are unable or…
Social Protection and HIV risk Factors among Youth in Southern Africa
Poverty fuels risky sexual behaviors associated with HIV infection among youth. Interventions like cash transfers may mitigate HIV risk. We explored the role of broader social protection (including food, educational, and social transfers) in reducing HIV risk among 15-24-year-olds in Southern Africa. We analyzed Population-based HIV Impact Assessment surveys data from 31,317 youth in eSwatini, Lesotho, Malawi, Namibia, Zambia, and Zimbabwe (2015-…
Implementation of Doxy-PEP in a Diverse Sexual Health Program in Northern Manhattan
This prospective cohort study evaluated the real-world effectiveness of doxycycline postexposure prophylaxis use in reducing bacterial sexually transmitted infections (STIs) within a diverse urban sexual health program. Propensity-matched analyses showed significant STI reductions, particularly in rectal Chlamydia trachomatis infections, among early adopters. Uptake was disproportionately higher in non-Hispanic White individuals and those more en…
Lessons learnt from daily oral PrEP delivery to inform national planning for PrEP ring introduction for women in low-income and middle-income countries
INTRODUCTION: Some African countries plan to introduce and scale-up new long-acting pre-exposure prophylaxis methods (LA-PrEP), like the monthly dapivirine vaginal ring (PrEP ring) and injectable cabotegravir. National costed implementation plans, roadmaps for successful product implementation, are often overlooked. International stakeholders engaged in oral PrEP planning, introduction and scale-up are an information resource of lessons learned t…
Rapid or Immediate ART, HIV Stigma, Medical Mistrust, and Retention in Care
Rapid or immediate antiretroviral therapy (iART) after HIV diagnosis improves linkage to care and time to viral suppression. However, iART may affect or be affected by HIV-related stigma and medical mistrust. In this mixed-methods pilot study, we examined the bi-directional role of HIV stigma, medical mistrust, and visit adherence (VA) in the context of iART in a diverse, newly diagnosed patient population. Participants were recruited from an HIV…
Race and Remdesivir
COVID-19 has disproportionately burdened communities of color. We observed no difference in median LOS between racial or ethnic groups, which supports the notion that the heterogeneous effect of remdesivir in the literature may be explained in part by underrecruitment or participation of Black, Hispanic, and Asian patients in clinical trials
Age-Restriction of a Validated Risk Scoring Tool Better Predicts HIV Acquisition in South African Women
We examined the predictive ability of the VOICE risk screening tool among adolescent girls and young women at heightened HIV risk in urban and peri-urban Kwa-Zulu-Natal, South Africa. Using participant data from CAPRISA 004's control arm (N = 444), we applied the initial VOICE risk screening score (IRS), a modified risk score (MRS) based on predictive and non-predictive variables in our data, and age-restricted (AIRS and AMRS, respectively). We e…
The Long-Acting Cabotegravir Tail as an Implementation Challenge
Immediate Antiretroviral Therapy
Immediate antiretroviral therapy (iART), defined as same-day initiation of ART or as soon as possible after diagnosis, has recently been recommended by global and national clinical care guidelines for patients newly diagnosed with human immunodeficiency virus (HIV). Based on San Francisco's Rapid ART Program Initiative for HIV Diagnoses (RAPID) model, most iART programs in the US condense ART initiation, insurance acquisition, housing assessment,…
Associations Between Economic Factors and Condom Use Behavior Among Female Sex Workers in Dakar and Mbour, Senegal
Use and Acceptability of HIV Self-Testing Among First-Time Testers at Risk for HIV in Senegal
HIV Self-Testing (HIVST) aims to increase HIV testing coverage and can facilitate reaching the UNAIDS 90-90-90 targets. In Senegal, key populations bear a disproportionate burden of HIV and report limited uptake of HIV testing given pervasive stigma and criminalization. In these contexts, HIVST may represent a complementary approach to reach populations reporting barriers to engagement with existing and routine HIV testing services. In this study…
Participation in research involving novel sampling and study designs to identify acute HIV-1 infection among minority men who have sex with men
HIV-1 infection disproportionally affects African-American and Latino men who have sex with men (MSM). Their inclusion in biomedical and behavioral research is critical to understanding and addressing HIV vulnerability. Using focus groups, we sought to understand the perceptions related to participating in biomedical research of acute/recent HIV-1 infection (AHI) using complex sampling and data collection methods to reach this hidden group at hig…
Sexual risk reduction among non-injection drug users
We conducted a randomized controlled trial of a sexual risk-reduction intervention targeting non-injection drug users (NIDUs) and members of their drug-use/sexual networks (N=270). The intervention was based primarily on the social-influencing approach, and was delivered in four sessions. Sexual risk behaviors were examined at baseline, and 3, 6, 9, and 12 months after the completion of the intervention using the vaginal equivalent episodes (VEE)…
