TL;DR: It is shown that antibiotics, cesarean section, and infant formula alter patterns of microbial acquisition and succession during the first 2 years of childhood, which illustrates the complexity of early-life microbiome development and its sensitivity to perturbation.

TL;DR: During the first month of the SARS-CoV-2 outbreak in New York City and with evolving testing criteria, most women with laboratory-confirmed infection admitted for delivery did not have symptoms of COVID-19, and disease severity was associated with higher rates of cesarean and preterm birth.

TL;DR: Although there was no distinct evidence of vertical transmission from mothers with SARS-CoV-2 to their newborns, perinatal morbidities among both mothers and newborns were observed, and Symptomatic mothers were more likely to experience premature delivery and their babies to require intensive care.

TL;DR: Interestingly, patients with pedunculated tumors persisted in having an improved survival even after correcting for vascular invasion, compared with patients having broad-based tumor attachment, and small tumor size also proved to be a significant and independent prognostic indicator for improved survival.

TL;DR: This is the first study showing long-term naturalization of the microbiota of CS-born infants by restoring microbial exposure at birth, and provides evidence of the pluripotential nature of maternal vaginal fluids to provide pioneer bacterial colonizers for the newborn body sites.
