Background: Preterm prelabor rupture of membranes (PPROM) before or around the limit of fetal viability is associated with serious maternal and neonatal complications including chorioamnionitis, extremely preterm birth, and pulmonary hypoplasia.

Objectives: To describe contemporary outcomes of extremely preterm infants born after prolonged periviable PPROM, and to identify perinatal factors associated with survival and survival without severe neurodevelopmental impairment (NDI).

Study Design: Among actively treated infants born alive at <27 weeks' gestational age (GA) in centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network from 2012 to 2018, the outcomes of survival and survival without severe NDI at 22-26 months' corrected age were compared between infants exposed to prolonged (≥120 hours) periviable (<24 weeks' GA) PPROM and unexposed infants born after rupture of membranes ≤18 hours before delivery or at delivery, adjusting for birth GA, sex, multiple gestation, antenatal steroids, small for gestational age (SGA), insurance, and center.

Objective: Evaluate the association between results of the room air (RA) challenge and death, respiratory morbidity, and neurodevelopmental impairment (NDI) at 2 years' corrected age.

Study Design: Cohort study of infants born <27 weeks' gestational age who underwent a RA challenge to determine BPD diagnosis at 36 weeks postmenstrual age.

Results: Of 1022 infants eligible for the RA challenge, 554 underwent testing and 223 passed.

Article Synopsis
  • Brain injury is closely linked to preterm birth, with complications like intestinal perforations contributing to long-term neurological issues that are not well understood.
  • The study found that subventricular zone echogenicity (SVE) on cranial ultrasound in preterm infants after intestinal perforations was associated with motor impairment at age 2.
  • Research in a neonatal mouse model showed that SVE involves specific cellular changes, suggesting that ultrasound detection of SVE could be an early indicator of neurodevelopmental impairment in preterm infants experiencing inflammatory conditions.

Importance: Maternal milk feeding of extremely preterm infants during the birth hospitalization has been associated with better neurodevelopmental outcomes compared with preterm formula. For infants receiving no or minimal maternal milk, it is unknown whether donor human milk conveys similar neurodevelopmental advantages vs preterm formula.

Objective: To determine if nutrient-fortified, pasteurized donor human milk improves neurodevelopmental outcomes at 22 to 26 months' corrected age compared with preterm infant formula among extremely preterm infants who received minimal maternal milk.

Objective: The Access, Watch and Reserve (AWaRe) list of antibiotics was developed by the WHO to support antibiotic stewardship programmes (ASP). The Access group incorporates first-line options, while Watch antibiotics have higher resistance potential or toxicity, and Reserve drugs should be used only for complex infections. ASP implementation has been challenged during the COVID-19 pandemic.
