Placental abruption and the risk of necrotizing enterocolitis in neonates with birth weight ≥1500 grams; US national database study.

Background: The pathogenesis of necrotizing enterocolitis (NEC) is multifactorial, placental abruption is associated with serious neonatal complications attributed to disruption of the maternal-fetal vascular interface. This study aimed to investigate the association between placental abruption and NEC.

Methods: We analyzed the United States (US) National Inpatient Sample (NIS) dataset for the years 2016-2018.

Acute Right-Sided Abdominal Pain in an Adolescent: Expect the Unexpected.
