[Effect of omega-3 supplementation during pregnancy and lactation on the fatty acid composition of breast milk in the first months of life: a narrative review].

Omega-3 long-chain, polyunsaturated fatty acids are essential, so they must be provided through the diet, as their biological synthesis is limited, making it essential to meet their requirements during physiological stages such as pregnancy and lactation. A narrative review was conducted on the effects of omega-3 supplementation during pregnancy and lactation on the fatty acid composition of breast milk in the first months of life. Eight randomized clinical studies were analyzed, showing a significant increase in docosahexaenoic acid (DHA) concentration in breast milk (BM) post-supplementation, compared to control groups.

[Exposition to drugs of abuse in pregnancy and breastfed babies growth in CONIN Valparaíso, Chile].

Introduction: Consequences related to drugs exposure during fetal life have been extensively studied. The present work explores the Chilean situation about this matter, characterizing growth of infants previously exposed to drugs during fetal life.

Objectives: Compare anthropometric measurements between neonates exposed to drugs due to maternal consumption during pregnancy and an unexposed control group from 0 -6 months of life.
