Question: Does maternal gestational diabetes mellitus (GDM) affect newborn gut microbiota and metabolomic profiles?
Finding: Neonates born to mothers with diet-controlled GDM exhibited reduced gut microbiota α-diversity, altered β-diversity, and metabolic shifts, including changes in fumarate and succinate levels, with peroxisome proliferator-activated receptor and adipocytokine signaling pathway activation.
Meaning: Maternal GDM affects early microbial colonization and metabolism in newborns and may have long-term health implications.

Purpose

The gut microbiota can influence several diseases through immune modulation; however, the exact role of microbes such as Clostridium difficileand the relationship between microbiota colonization and allergic diseases are not well known. This study aimed to determine the relationship between C. difficilecolonization and/or infection (CDCI) during infancy and allergic diseases during early childhood.

Methods

Infants 1–12 months of age presenting changes in...
