Tenofovir Disoproxil Fumarate/Emtricitabine Prophylaxis Has No Effect on Bone Mineral Density and Bone Mineral Content in African Breastfeeding Women Receiving Pre-Exposure Prophylaxis for HIV.

Background: Tenofovir disoproxil fumarate (TDF) when used as preexposure prophylaxis (PrEP) in pregnancy is considered safe overall however there is insufficient evidence of its effect on maternal bone. We compared bone mineral density (BMD) and content (BMC) at the lumbar spine (LS) and hip of African breastfeeding women exposed and not exposed to TDF-containing PrEP in a randomized control trial (RCT).

Methods: This is a secondary data analysis of an RCT where pregnant women were randomized to initiating PrEP in pregnancy or delayed initiation of PrEP until breastfeeding cessation.

In-utero exposure to tenofovir-containing pre-exposure prophylaxis and bone mineral content in HIV-unexposed infants in South Africa.

Introduction: Tenofovir disoproxil fumarate (TDF) is a common drug of choice for pre-exposure prophylaxis (PrEP) or as a combination HIV treatment for pregnant women. In-utero exposure to TDF was found to be associated with lower bone mineral content (BMC) in HIV-exposed uninfected neonates. Data for infants born to women taking TDF-PrEP are lacking.

exposure to tenofovir disoproxil fumarate pre-exposure prophylaxis and growth metrics in HIV unexposed breastfed infants in South Africa: a analysis of the CAP 016 PrEP in pregnancy RCT.

Objective: We evaluated growth metrics in HIV unexposed African breastfed infants in the first 18 months of life in association with exposure to Tenofovir Diphosphate Fumarate (TDF) containing pre-exposure prophylaxis (PrEP).

Design: We conducted a secondary data analysis of a TDF-PrEP randomized control trial (CAP016 RCT). Pregnant women without HIV were randomized to initiating TDF-PrEP in pregnancy (Immediate-PrEP-IP) or deferred initiation of TDF-PrEP at cessation of breastfeeding (Deferred-PrEP-DP).

Investigating the antimicrobial potential of bovine lactoferrin against the neonatal pathogen, Staphylococcus capitis.

Lactoferrin is an antimicrobial glycoprotein that demonstrates a broad-spectrum of activity against a wide variety of clinical pathogens. This study investigated the potential of bovine lactoferrin (bLf) against multidrug resistant Staphylococcus capitis (S. capitis) strains.

Prenatal Congenital Heart Disease and Placental Phenotypes: Preserved Neonatal Weight Despite Small Placentas.

Background: Congenital heart disease (CHD) affects 8 in 1,000 live births with significant postnatal implications including growth failure, neurodevelopmental delay, and mortality. The placenta develops concomitantly with the fetal heart. High rates of placental pathology and discordant growth in pregnancies affected by CHD highlight the significance of the fetal-placental-cardiac axis.
