Extreme prematurity in healthy 5-year-old children: a re-analysis of sex effects on event-related brain activity.

A male disadvantage has been reported in several outcome studies of children born preterm. Twenty-two healthy premature children (10 girls, 12 boys) born between 25 and 28 weeks of gestation and 20 controls born full-term (10 boys, 10 girls) were matched on socioeconomical status and age. Event-related potentials (ERPs) were recorded by using 14 electrodes in a visual oddball task, with 75% frequent and 25% rare stimuli.

Nursery Neurobiologic Risk Score and outcome at 18 months.

The aim of this study was to confirm the predictive value of the nursery Neurobiologic Risk Score. Prospectively, 121 infants (mean birthweight 961 +/- 179 g, gestation 27.0 +/- 1.

Developmental pathways leading to externalizing behaviors in 5 year olds born before 29 weeks of gestation.

Longitudinal data for 62 infants born before 29 weeks of gestation were used to assess the influence of four factors (i.e., neonatal health, family environment, language skill, and nonverbal ability) on the parental report of hyperactive and oppositional behaviors of children at 5 years 9 months.

Health and developmental outcomes at 18 months in very preterm infants with bronchopulmonary dysplasia.

Objective: To determine whether very preterm infants who are oxygen-dependent at 28 days of life but not at 36 weeks' gestational age are at high risk of morbidities at 18 months.

Population: A total of 217 infants born in a tertiary care center at 24 to 28 weeks' gestation in 1987 to 1992, classified into three groups: neonatal comparison group, O2 <28 days of life (n = 76); bronchopulmonary dysplasia (BPD)-1, O2 >/=28 days but not at 36 weeks' gestational age (n = 48); and BPD-2, O2 >/=36 weeks (n = 93).

Outcome Measures: Growth, persistent respiratory problems (asthma, tracheostomy, home oxygen therapy), surgery, hospitalizations, and neurodevelopmental impairments.

A topographical ERP study of healthy premature 5-year-old children in the auditory and visual modalities.

The aim of this research is to study the impact of extreme prematurity on the cognitive development of the child as assessed at age 5 years 9 months. Our samples include 15 healthy prematures born between 25 and 28 weeks of gestational age carefully matched with 15 full-term controls. In the first experiment, two different auditory stimuli were presented to the subjects who listened passively without instruction.
