Silencing Map3k7 suppresses pyroptosis to alleviate bronchopulmonary dysplasia through inhibiting the TGF-β1/Smad3 pathway.

Bronchopulmonary dysplasia (BPD) is a serious complication in premature infants. This study aimed to investigate the mechanism of mitogen-activated protein 3 kinase 7 (Map3k7) affecting BPD by regulating caspase-1 mediated pyroptosis. The morphology of the lung tissue was observed using hematoxylin-eosin staining.

Bacterial endotoxin-induced maternal inflammation leads to fetal intestinal injury and affects microbial colonization in the neonatal period.

Background: Intraamniotic infection is associated with an increased risk of multiple adverse outcomes in offspring, especially neonatal necrotizing enterocolitis (NEC), which is one of the serious gastrointestinal diseases in neonates. However, the underlying mechanism remains undefined. We hypothesize that bacterial endotoxin-induced maternal inflammation causes intestinal injury in offspring, thereby affecting the composition of the intestinal microbiome.

Effects of β-Lactam Antibiotics on Gut Microbiota Colonization and Metabolites in Late Preterm Infants.

We usually refer to the critical period for intestinal flora establishment as infancy because the infant gut microbiota is characterized by low diversity and poor stability compared with that of adults. Moreover, it is also vulnerable to interference from a variety of factors. As β-lactam antibiotics are typically used in newborn infants with infectious diseases, we used 16S rDNA sequencing and LC-MS metabolomics to analyze fecal microbes and metabolites in 16 late preterm infants with or without β-lactam antibiotic treatment.
