Determinants of Adherence to National Infant Feeding Guidelines by Black Mothers Living with HIV.

Objective: Worldwide, 160,000 children were newly infected with HIV in 2018; half of these were infected through breastfeeding. Infant feeding guidelines are distinct depending on each country's resources and national or sub-national guidelines. Because of divergent guidelines, the best infant feeding approach to prevent mother-to-child transmission can become unclear.

Neonatal kidney size and function in preterm infants: what is a true estimate of glomerular filtration rate?

Objectives: To distinguish between cystatin C (CysC) and creatinine (Cr) as markers of estimated glomerular filtration rate (eGFR) in preterm infants and to correlate eGFR with total kidney volume (TKV) as a surrogate of nephron mass.

Study Design: Sixty preterm (<37 weeks' gestational age [GA]) and 40 term infants were enrolled at birth. Serum Cr and CysC levels were assessed during the first week of life.
