Time to diagnosis for breast, cervical and colorectal cancer in Zimbabwe and South Africa
INTRODUCTION: Shorter time to diagnosis may lead to better cancer outcomes in Southern Africa. This study measured the time from symptoms to first healthcare visit (patient interval; PI) and diagnosis (diagnostic interval; DI) and associated factors for breast, cervical and colorectal cancer in Zimbabwe and South Africa (SA). METHODS: A cross-sectional survey collected data on socio-demographics, cancer awareness, barriers to seeking care, sympto…
Neutralizing antibody responses over time in a demographically and clinically diverse cohort of individuals recovered from Sars-CoV-2 acquisition in Africa
COVID-19 has affected millions worldwide. Research characterized immune responses of individuals who acquired SARS-CoV-2 and identified co-factors, such as HIV, associated with greater likelihood of poor clinical outcomes. SARS-CoV-2-specific neutralizing antibodies (nAbs) are a strong correlate of protection but their elicitation in people living with HIV (PLWH), and particularly in southern Africa, is less well characterized. HVTN 405/HPTN 1901…
“We chose PrEP because I wanted to be sure that this child my wife was going to conceive was indeed mine.” Factors influencing the choice of safer conception methods and experiences with its use
The differences in method preferences and experiences voiced by participants in this study and in other studies from the region point to the importance of having a variety of safer conception options in the service delivery package and addressing concerns about paternity, intimacy, and method-related attributes to enable HIV sero-discordant couples to safely achieve their reproductive goals
Preventing HIV and achieving pregnancy among HIV sero-different couples
Safer conception services are needed to minimize HIV transmission among HIV sero-different couples desiring pregnancy. Few studies have evaluated the choices couples make when offered multiple safer conception methods or real-world method acceptability and effectiveness. We piloted a comprehensive safer conception program ( Clintrials . gov identifier: NCT03049176) for HIV sero-different couples planning pregnancy in Zimbabwe to measure feasibili…
Preferences and Acceptability of Vaginal Delivery Forms for HIV Prevention Among Women, Male Partners and Key Informants in South Africa and Zimbabwe
Community-based self-collected human papillomavirus screening in rural Zimbabwe
Integration of HR-HPV screening into existing community outreach models for HIV and immunizations could facilitate population-based screening to scale cancer control and prevention programs in sub-Saharan Africa. Community/village health workers (CHW/VHW) and village outreach programs offer a potential option for cervical cancer screening programs to move towards improving access of sexual and reproductive health resources for women at highest ri…
Efficacy is Not Everything
As new female-initiated HIV prevention products enter development, it is crucial to incorporate women's preferences to ensure products will be desired, accepted, and used. A discrete-choice experiment was designed to assess the relative importance of six attributes to stated choice of a vaginally delivered HIV prevention product. Sexually active women in South Africa and Zimbabwe aged 18-30 were recruited from two samples: product-experienced wom…
Anal human papillomavirus infection in HIV-positive men and women at two opportunistic infections clinics in Harare, Zimbabwe
Overall anal HPV prevalence was 44% in this mostly heterosexual HIV-positive population. Oncogenic HPV types accounted for almost half of infections, supporting the need for surveillance of anal cancer in this population
How Presentation of Drug Detection Results Changed Reports of Product Adherence in South Africa, Uganda and Zimbabwe
Use of a Vaginal Ring Containing Dapivirine for HIV-1 Prevention in Women
BACKGROUND: Antiretroviral medications that are used as prophylaxis can prevent acquisition of human immunodeficiency virus type 1 (HIV-1) infection. However, in clinical trials among African women, the incidence of HIV-1 infection was not reduced, probably because of low adherence. Longer-acting methods of drug delivery, such as vaginal rings, may simplify use of antiretroviral medications and provide HIV-1 protection. METHODS: We conducted a ph…
Reporting of Adherence in the Voice Trial
Tenofovir-Based Preexposure Prophylaxis for HIV Infection among African Women
BACKGROUND: Reproductive-age women need effective interventions to prevent the acquisition of human immunodeficiency virus type 1 (HIV-1) infection. METHODS: We conducted a randomized, placebo-controlled trial to assess daily treatment with oral tenofovir disoproxil fumarate (TDF), oral tenofovir-emtricitabine (TDF-FTC), or 1% tenofovir (TFV) vaginal gel as preexposure prophylaxis against HIV-1 infection in women in South Africa, Uganda, and Zimb…
