Background: Injectable depot medroxyprogesterone acetate (DMPA) is the most common contraceptive choice among young women in Uganda, where HIV burden is high and HIV pre-exposure prophylaxis (PrEP) may be offered. For young women who choose to use both agents concurrently, it is unknown whether they will experience declines in BMD beyond those elicited by either product singly.
Methods: From 2018-2022, we conducted a 2-year prospective study with women ages 16-25 years in Kampala, Uganda desiring pregnancy and HIV prevention.

Introduction Anti-tumor necrosis factor alpha (TNFα) therapies have revolutionized the management of Crohn's disease (CD). However, they increase the risk of viral reactivation, particularly hepatitis B virus (HBV). This study aims to define the HBV serological profiles of patients with CD who are candidates for biological therapy, identifying profiles at potential risk for reactivation or exacerbation following immunosuppressive treatment.

Background: Female sex workers remain disproportionately affected by HIV. The aim of this study was to determine the effect of risk-differentiated, peer-led support for female sex workers in Zimbabwe on the risk of HIV acquisition and HIV transmission from sex among female sex workers.
Methods: In this cluster randomised, open-label, controlled study, 22 clinics dedicated to female sex workers co-located in government health facilities throughout Zimbabwe were allocated (1:1, through restricted randomisation) to usual care or AMETHIST intervention.
Female Genital Tract Host Factors and Tenofovir and Lamivudine Active Metabolites.

Department of Experimental and Clinical Pharmacology, College of Pharmacy, University of Minnesota, Minneapolis.
Background: We previously reported the effect of contraception on cervical tenofovir concentrations in Ugandan women with human immunodeficiency virus (HIV). Here we explored the role of cervicovaginal cytokines and drug metabolizing enzymes and transporters (DMETs) to elucidate female genital tract (FGT) drug disposition in a Ugandan cohort.
Methods: Cervicovaginal fluid and cervical biopsies were collected from Ugandan women with HIV receiving tenofovir/lamivudine-based therapy and intramuscular depot medroxyprogesterone acetate (n = 25), copper intrauterine device (cuIUD; n = 12), or condoms (n = 13) as contraception.
