Background: Adults with the apolipoprotein E (APOE) gene alleles e4 and e2 are at high risk of poor neurological outcome after brain injury. The e4 allele has been associated with cerebral palsy (CP), and the e2 allele has been associated with worse neurological outcome with congenital heart disease. This study was done to test the hypothesis that the APOE genotype is associated with outcome among neonates who survive after hypoxic-ischemic encephalopathy (HIE).

Study Design: We conducted a cohort study of infants born with birth weight of 401 to 1000 g and gestational age of 23 to 30 weeks. DR-CPR was defined as chest compressions, medications, or both.
Objective: To examine the predictive validity of the amplitude integrated electroencephalogram (aEEG) and stage of encephalopathy among infants with hypoxic-ischemic encephalopathy (HIE) eligible for therapeutic whole-body hypothermia.
Design: Neonates were eligible for this prospective study if moderate or severe HIE occurred at <6 hours and an aEEG was obtained at <9 hours of age. The primary outcome was death or moderate/severe disability at 18 months.
Background: It is unclear whether aggressive phototherapy to prevent neurotoxic effects of bilirubin benefits or harms infants with extremely low birth weight (1000 g or less).
Methods: We randomly assigned 1974 infants with extremely low birth weight at 12 to 36 hours of age to undergo either aggressive or conservative phototherapy. The primary outcome was a composite of death or neurodevelopmental impairment determined for 91% of the infants by investigators who were unaware of the treatment assignments.
Objective: To compare the incidence of apnea, bradycardia, or desaturation in a car seat with that in a car bed for preterm very low birth weight (< or = 1500 g) infants.
Study Design: Infants were studied for 120 minutes in a car seat and in a car bed. Apnea (> 20 seconds), bradycardia (heart rate < 80/min for > 5 seconds), desaturation (SpO2 < 88% for > 10 seconds), and absent nasal flow were monitored.
Background: There is a paucity of information on the maintenance of body temperature at birth for low birth weight infants.
Objectives: We examined the distribution of temperatures in low birth weight infants on admission to the NICUs in the Neonatal Research Network centers and determined whether admission temperature was associated with antepartum and birth variables and selected morbidities and mortality.
Methods: Infants without major congenital anomalies born during 2002 and 2003 with birth weights of 401 to 1499 g who were admitted directly from the delivery room to the NICU were included.
The contribution of intrapartum hypoxia-ischemia to neonatal encephalopathy in the larger preterm infant remains poorly defined. Such infants could become potential candidates for neuroprotective strategies. The objective of this study was to determine in preterm infants of gestation 31 to 36 weeks, with severe fetal acidemia (i.

Methods: A retrospective chart review was conducted of 185 term infants who were admitted to the neonatal intensive care unit between January 1993 and December 2002 with an umbilical arterial pH <7.00.
Objective: To determine the growth and neurodevelopmental outcome, as well as predictors of the latter in extremely low-birth-weight (ELBW) infants with definitive necrotizing enterocolitis (NEC).
Study Design: Case - control analysis. In all, 17 ELBW infants <1000 g with Stage 2 or 3 NEC were matched to 51 control infants without NEC.
Objective: To determine patterns of survival for very low birth weight (VLBW, birth weight 501 to 1500 g) neonates over 23 years.
Study Design: Data for 4873 VLBW neonates born from 1977 to 2000 were divided into five epochs. The primary outcome was survival to hospital discharge.
Objectives: To assess the outcome of extremely low birth weight (ELBW) infants < or =1000 g as it relates to antenatal steroids (ANS) therapy.
Study Design: A retrospective analysis of 124 infants born between January 1995 and December 1997. Infants born to mothers with pregnancy-induced hypertension, diabetes, and severe growth restriction were excluded.
Background: Recent studies of preterm neonates have indicated that antenatal dexamethasone (ADX) may have adverse effects on cranial ultrasound findings at the time of hospital discharge, including periventricular leukomalacia. Furthermore, both ADX and postnatal dexamethasone (PDX) may have adverse effects on subsequent neurodevelopmental outcome.
Objectives: 1) To assess the effects of ADX exposure on cranial ultrasound findings at the time of hospital discharge and 2) to evaluate the individual effects of ADX and/or PDX exposure on subsequent neurodevelopmental outcome in extremely low birth weight (ELBW) neonates in whom confounding risk factors known to influence outcome were controlled.
