Benzathine penicillin G stockouts and other barriers to documented syphilis treatment in pregnancy in Zambia.

Objective: The prevalence of syphilis in Zambia remains high and is a critical public health concern. The Zambian Ministry of Health recommends universal screening and same-day treatment for syphilis in pregnancy, yet the syphilis screening rate is low, and treatment is poorly documented. The goal of this study was to document syphilis treatment rates and associated factors among pregnant women in care in Zambia.

Growth patterns of infants with in- utero HIV and ARV exposure in Cape Town, South Africa and Lusaka, Zambia.

Background: Infants born HIV-exposed yet remain uninfected (HEU) are at increased risk of poorer growth and health compared to infants born HIV-unexposed (HU). Whether maternal antiretroviral treatment (ART) in pregnancy ameliorates this risk of poorer growth is not well understood. Furthermore, whether risks are similar across high burden HIV settings has not been extensively explored.

Impact of the Umoyo mother-infant pair model on HIV-positive mothers' social support, perceived stigma and 12-month retention of their HIV-exposed infants in PMTCT care: evidence from a cluster randomized controlled trial in Zambia.

Background: Public health systems in resource-constrained settings have a critical role to play in the elimination of HIV transmission but are often financially constrained. This study is an evaluation of a mother-infant-pair model called "Umoyo," which was designed to be low cost and scalable in a public health system. Facilities with the Umoyo model dedicate a clinic day to provide services to only HIV-exposed infants (HEIs) and their mothers.
