Objective: To identify rates of overweight (body mass index [BMI] ≥85th percentile) and obesity (BMI ≥95th percentile) at 6-7 years of age and associated risk factors among extremely preterm infants born at <28 weeks of gestation. Study design: Anthropometrics, blood pressure, and active and sedentary activity levels were prospectively assessed....

Objectives: To identify variables associated with successful elective extubation, and to determine neonatal morbidities associated with extubation failure in extremely preterm neonates. Study design: This study was a secondary analysis of the National Institute of Child Health and Human Development Neonatal Research Network's Surfactant, Positiv...

Objective: To characterize actual achieved patterns of oxygenation in infants born appropriate vs small for gestational age (SGA) randomized to a lower (85-89%) vs higher (91%-95%) oxygen saturation target in the Surfactant Positive Pressure and Oxygen Trial. To determine the association between achieved oxygen saturation levels and survival in in...

Objective: To assess the association between prophylactic indomethacin and bronchopulmonary dysplasia (BPD) in a recent, large cohort of extremely preterm infants. Study design: Retrospective cohort study using prospectively collected data for infants with gestational ages < 29 weeks or birth weights of 401-1000 g born between 2008 and 2012 at p...
