breastfeeding

The risk of HIV transmission through breastfeeding is very low, but it is not non-existent in women living with HIV who have undetectable levels in their blood. Now, for the first time, a study published in the Annals of Internal Medicine has been able to test for HIV in the milk of two such women: one elite controller (who maintains low viral loads without antiretrovirals) and another who had been on treatment for years. Although small amounts of viral DNA were found, the virus was not infectious. The results show that such testing is possible and help confirm the very low risk of transmission.

A case-control study published in JAMA Pediatrics reports a relationship between certain aberrant metabolic biomarkers at birth and sudden infant death syndrome (SIDS). Although the research is preliminary and no screening test for this syndrome is yet available, the researchers believe their study is an important step toward integrating metabolic and genetic markers to identify infants at higher risk of sudden death.

A series on breastfeeding published today in The Lancet highlights the economic and political power of formula companies, examines their marketing practices and the impact this has on the health of mothers and children.

Research with 11 lactating women vaccinated against covid-19 has found small amounts of mRNA from the vaccine in breast milk, undetectable 48 hours later.
