Background—Heat-treated expressed breastmilk is recommended by WHO as an option to reduce vertical HIV transmission in resource poor regions. Flash-heat (FH) is a low technology pasteurization method developed for home use, but its effect on quantity and quality of breastmilk immunoglobulins is unknown. Objective—To evaluate FH's effect on breastmilk immunoglobulin levels and antigen binding capacity. Design/Methods—Fifty HIV+ mothers in South Africa provided breastmilk. Part of each sample served as an unheated (UH) control; the remainder was Flash-heated. Total and antigen-specific IgA and IgG were measured by ELISA. Paired t-test was performed on log transformed data. Results—FH significantly decreased total IgA …

(EBM) as one method to reduce postnatal transmission of human immunodeficiency virus (HIV) in developing countries. Flash-heat is a simple heat treatment method shown to inactivate cell-free HIV. Objective—To determine the effect of flash-heat on vitamin content of milk. Methods—Fresh EBM was collected from 50 HIV+ mothers in Durban, South Africa. Mothers washed their hands and then manually expressed 75–150 mL EBM into sterile jars. Milk was aliquoted to unheated controls or flash-heat (50 mL EBM in a glass jar heated in a 450-mL water jacket in an aluminum pan until water boiled, then EBM removed) simulating field conditions with …

Background. A large proportion of resources allocated to the Community-Based Nutrition Programme (CBNP) of the Department of Health in the Western Cape is spent on crèche-feeding schemes. To date, little evaluation of the CBNP has been undertaken. Aim. A cross-sectional study was conducted to assess the nutritional adequacy of meals provided, and facilities available, at state-funded crèches in the Cape Metropole. Methods. A questionnaire was administered to managers of 43 conveniently sampled crèches in two districts of Cape Town. Twenty-two of the crèches were randomly selected for nutrient assessment of a duplicate meal, and a typical meal sample was weighed …
