Studies of biomarkers of putative breast carcinogens, such as DNA adducts, have been limited by the difficulty in obtaining representative ductal epithelial cells (DECs) from breast tissue. In this feasibility study, we sought to ascertain if exfoliated DECs in breast milk could be a source of DNA for biomarker studies. Specimens (n = 38) were collected over 24 h from nursing women, and a quest...

OBJECTIVE Beneficial effects of breast milk on cognitive skills and behavior ratings have been demonstrated previously in term and very low birth weight infants. Extremely low birth weight infants are known to be at increased risk for developmental and behavior morbidities. The benefits of breast milk that is ingested in the NICU by extremely low birth weight infants on development and behavior...

Tuberculosis (TB) cellular immune responses were examined in the breast milk of human immunodeficiency virus infected mothers using the T-SPOT. TB interferon-gamma release assay (IGRA). Positive TB interferon-gamma (IFN-γ) responses were detected in 6 of 8 (75%) valid breast milk assays. Among 7 mothers with paired breast milk and blood assays, TB IFN-γ responses were higher in breast milk than...

www.aafp.org/afp AMERICAN FAMILY PHYSICIAN 119 largely determined by the maternal serum drug concentration. This serum concentration tends to be lower with medications that have large volumes of distribution and fluctuates more with medications that have short half-lives. Retrograde diffusion of the drug from breast milk to plasma may remove a medication from the milk even if the mother has not...

The importance of breast milk for the growing infant is undisputed; breastfeeding decreases infantile mortality by tenfold and decreases the incidence of infectious diseases. Despite its recognized benefits, the structural richness of breast milk has also impeded the characterization of the multiple effects of milk components on infant physiology. However, the important roles of some components...

Breast milk is the primary source of nutrition for newborns, and is rich in immunological components. MicroRNAs (miRNAs) are present in various body fluids and are selectively packaged inside the exosomes, a type of membrane vesicles, secreted by most cell types. These exosomal miRNAs could be actively delivered into recipient cells, and could regulate target gene expression and recipient cell ...

a case in which a baby was not infected by breast milk from his EBOV-positive mother. However, it should be noted that the woman’s breast milk was never tested while she was breast-feeding baby 2. The literature on EBOV in breast milk of EBOV-positive patients is extremely scarce (3). In a previous study from the 2000 Sudan EBOV outbreak in Gulu, Uganda, breast milk from a convalescent-phase pa...

OBJECTIVES To compare the effect of donor breast milk with infant formula in preterm infants. Separate comparisons with formula were made for donor breast milk that was: (1) given as a sole diet; (2) given as a supplement to mother's own breast milk; and (3) fortified with macronutrients and micronutrients. The main outcomes were death, necrotising enterocolitis (NEC), infection, growth and dev...

The mechanisms controlling innate microbial recognition in the neonatal gut are still to be fully understood. We have sought specific regulatory mechanisms operating in human breast milk relating to TLR-mediated microbial recognition. In this study, we report a specific and differential modulatory effect of early samples (days 1-5) of breast milk on ligand-induced cell stimulation via TLRs. Alt...
