Impact of maternal infection on outcomes in extremely preterm infants.

Background: Infants born less than 29 weeks, or extremely preterm (EPT), experience increased morbidity and mortality. We hypothesized that exposure to maternal infection might contribute to neurodevelopmental impairment (NDI) or death at 2 years of age.

Methods: We conducted a retrospective cohort study of EPT infants from January 2010 to December 2020.

Molecular Epidemiology of Invasive Staphylococcus aureus Infections and Concordance with Colonization Isolates.

Objectives: To characterize Staphylococcus aureus isolates recovered from hospitalized children and to determine the concordance between colonizing and invasive isolates.

Study Design: Children with culture-confirmed, community-onset, invasive S aureus infections were enrolled in this prospective case series from a large children's hospital over a 5-year period. Colonization isolates were obtained from the anterior nares, oropharynx, and inguinal folds and were compared with invasive isolates via repetitive-element, sequence-based polymerase chain reaction testing.
