Violence Exposure Among Women in the Sex Industry and Their Children in El Alto, Bolivia: A Comparative Cross-Sectional Study.

We conducted a comparative cross-sectional study to compare the prevalence of exposure to workplace violence and intimate partner violence (IPV) in 125 female sex workers (FSWs) and 125 age-matched control women working in other professions (non-FSWs) and their children in El Alto, Bolivia. Violence exposure was assessed using the Demographic Health Survey Domestic Violence Module. To determine associations between work type and violence exposure, we conducted multivariate logistic regression. One-third of working mothers experienced sexual IPV, regardless of their profession. FSWs experienced higher rates of severe physical IPV and workplace violence. Children of FSWs were approximately three times more likely to be exposed to violence in the workplace. In Bolivia, strategies to reduce exposure to violence within the home and in FSW workplaces are paramount to minimizing negative impacts on women and their children. These findings have implications for policies to improve education, living wages, and social interventions to prevent and mitigate violence against women and children.

Two Randomized Trials of Neutralizing Antibodies to Prevent HIV-1 Acquisition

BACKGROUND­Whether a broadly neutralizing antibody (bnAb) can be used to prevent human immunodeficiency virus type 1 (HIV-1) acquisition is unclear. METHODS­We enrolled at-risk cisgender men and transgender persons in the Americas and Europe in the HVTN 704/HPTN 085 trial and at-risk women in sub-Saharan Africa in the HVTN 703/HPTN 081 trial. Participants were randomly assigned to receive, every 8 weeks, infusions of a bnAb (VRC01) at a dose of either 10 or 30 mg per kilogram (low-dose group and high-dose group, respectively) or placebo, for 10 infusions in total. HIV-1 testing was performed every 4 weeks. The VRC01 80% inhibitory concentration (IC80) of acquired isolates was measured with the TZM-bl assay. RESULTS­Adverse events were similar in number and severity among the treatment groups within each trial. Among the 2699 participants in HVTN 704/HPTN 085, HIV-1 infection occurred in 32 in the low-dose group, 28 in the high-dose group, and 38 in the placebo group. Among the 1924 participants in HVTN 703/HPTN 081, infection occurred in 28 in the low-dose group, 19 in the high-dose group, and 29 in the placebo group. The incidence of HIV-1 infection per 100 person-years in HVTN 704/HPTN 085 was 2.35 in the pooled VRC01 groups and 2.98 in the placebo group (estimated prevention efficacy, 26.6%; 95% confidence interval [CI], −11.7 to 51.8; P = 0.15), and the incidence per 100 person-years in HVTN 703/HPTN 081 was 2.49 in the pooled VRC01 groups and 3.10 in the placebo group (estimated prevention efficacy, 8.8%; 95% CI, −45.1 to 42.6; P = 0.70). In prespecified analyses pooling data across the trials, the incidence of infection with VRC01-sensitive isolates (IC80
