Prognostic models for stillbirth and neonatal death in very preterm birth: a validation study.

Objectives: To validate externally 2 prognostic models for stillbirth and neonatal death in very preterm infants who are either known to be alive at the onset of labor or admitted for neonatal intensive care.

Patients And Methods: All infants, with gestational age 22 to 32 weeks, of European ethnicity, known to be alive at the onset of labor (n = 17 582) and admitted for neonatal intensive care (n = 11 578), who were born in the Netherlands between January 1, 2000, and December 31, 2007. The main outcome measures were stillbirth or death within 28 days for infants known to be alive at the onset of labor and death before discharge from the NICU for infants admitted for intensive care.

Neurodevelopmental outcome in full-term newborns with refractory neonatal seizures.

Aim: This retrospective study describes the prognosis of full-term newborns with refractory neonatal seizures, comparing the need for treatment with two versus three or more antiepileptic drugs.

Methods: We reviewed our database (January 2002-December 2007) to include newborns with refractory neonatal seizures and abnormal electroencephalogram. Group A consisted of 17 newborns with two antiepileptic drugs.

Long-term neurodevelopmental outcome of monochorionic and matched dichorionic twins.

Background: Monochorionic (MC) twins are at increased risk for perinatal mortality and serious morbidity due to the presence of placental vascular anastomoses. Cerebral injury can be secondary to haemodynamic and hematological disorders during pregnancy (especially twin-to-twin transfusion syndrome (TTTS) or intrauterine co-twin death) or from postnatal injury associated with prematurity and low birth weight, common complications in twin pregnancies. We investigated neurodevelopmental outcome in MC and dichorionic (DC) twins at the age of two years.

Functioning at school age of moderately preterm children born at 32 to 36 weeks' gestational age.

Objective: To study outcome of low-risk moderately preterm birth between 32 and 36/7 weeks' gestation.

Methods: 377 Moderately preterm children (M: 34.7, SD: 1.

Functional outcomes and participation in young adulthood for very preterm and very low birth weight infants: the Dutch Project on Preterm and Small for Gestational Age Infants at 19 years of age.

Objective: Young adults who were born very preterm or with a very low birth weight remain at risk for physical and neurodevelopmental problems and lower academic achievement scores. Data, however, are scarce, hospital based, mostly done in small populations, and need additional confirmation.

Methods: Infants who were born at < 32 weeks of gestation and/or with a birth weight of < 1500 g in The Netherlands in 1983 (Project on Preterm and Small for Gestational Age Infants) were reexamined at age 19.

Outcome of perinatal care for very preterm infants at 5 years of age: a comparison between 1983 and 1993.

Perinatal mortality in very preterm infants has decreased by up to 50% during the last decades. Studies of changes of long-term outcome are inconclusive. We studied the visual, auditory, neuromotor, cognitive and behavioural development of two geographically defined populations of very preterm, singleton infants, born in 1983 and in 1993, and analysed the relationship between perinatal risk factors and outcomes.

Lower mortality but higher neonatal morbidity over a decade in very preterm infants.

Better perinatal care has led to better survival of very preterm children, but may or may not have increased the number of children with cerebral and pulmonary morbidity. We therefore investigated the relationship between changes in perinatal care during one decade, and short-term outcome in very preterm infants. Perinatal risk factors and their effects on 28-day and in-hospital mortality, and on intraventricular haemorrhage and bronchopulmonary dysplasia (BPD) in survivors, were compared in two surveys of very preterm singleton infants in the Netherlands.

Is paediatric assessment of motor development of very preterm and low-birthweight children appropriate?

Aim: To determine whether paediatricians that examine, in regular clinical practice, very preterm and very-low-birthweight children at 5 y of age detect neurological impairments and functional motor problems in these children.

Methods: We compared a paediatric judgement, a standardized neurological examination (Touwen examination) and a screening of motor development (Denver Developmental Screening Test; DDST) with the Movement ABC in 396 5-y-old very preterm and low-birthweight children.

Results: The Movement ABC detected clinically important motor disorders in 20.
