Changing Dutch approach and trends in short-term outcome of periviable preterms.

Background: In 2006, the Dutch guideline for active treatment of extremely preterm neonates advised to lower the gestational age threshold for active intervention from 26 0/7 to 25 0/7 weeks gestation.

Objective: To evaluate the association between the guideline modification and early neonatal outcome.

Design: National cohort study, using prospectively collected data from The Netherlands Perinatal Registry.

[The impact of a premature birth on the family; consequences are experienced even after 19 years].

Objective: A premature birth can cause parental stress, anxiety and uncertainty. This study illustrates the long-term consequences of a preterm birth for family life.

Design: Retrospective study by questionnaire.

Development of a movement quality measurement tool for children.

Background: Pediatric physical therapists assess the quantity and quality of children's motor skills. Several quantitative motor tests are currently available, but a concise measurement tool of observable movement quality (OMQ) is lacking.

Objective: The purpose of this study was to develop an OMQ measurement tool for children from the perspective of pediatric physical therapists.

Unstable longitudinal motor performance in preterm infants from 6 to 24 months on the Bayley Scales of Infant Development--Second edition.

Preterm birth increases the risk for neurologic and developmental disabilities and therefore long-term follow-up is important. This prospective follow-up study aims to describe longitudinal motor performance in preterm infants from 6 to 24 months and to detect the influence of risk factors on motor performance trajectories. We included preterm infants (n=348) with a gestational age of ≤32 weeks.

Weight of in vitro fertilization and intracytoplasmic sperm injection singletons in early childhood.

Birth weight and longitudinal growth in the first 4 years of life of term singletons conceived with the use of IVF and intracytoplasmic sperm injection (ICSI) were compared with those of naturally conceived singletons. Although IVF and ICSI singletons had a statistically significantly lower birth weight than naturally conceived singletons, the average individual weight curves showed that this difference was lost before the age of 4 years in all subgroups: IVF, ICSI, boys, and girls.

Neonatal end-of-life decisions and bioethical perspectives.

In the nineties the EURONIC project documented the staff views and practices regarding ethical decision-making in neonatal intensive care units of eight Western Europe countries: France, Germany, Great Britain, Italy, Luxembourg, Netherlands, Spain and Sweden. This paper reviews the changes occurred in the ethical and legal background of these countries, and discusses possible influences on neonatal care practices. To a certain extent, many of these changes appear to be in line with the neonatal physicians' views and attitudes previously documented by the EURONIC project, while some are not.

A model to predict motor performance in preterm infants at 5 years.

Background: Approximately 60% of preterm infants who are assessed at 5 years for motor performance in a standardized multidisciplinary follow-up program are found to have normal results, indicating that, for these children, routine motor assessment at this age is unnecessary.

Aim: To improve the efficiency of our follow-up practice for motor assessment by developing a model to predict motor performance of preterm infants at 5 years with a maximal sensitivity (>or=90%).

Study Design: Longitudinal design.

Motor performance in five-year-old extracorporeal membrane oxygenation survivors: a population-based study.

Introduction: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a cardio-pulmonary bypass technique to provide life support in acute reversible cardio-respiratory failure when conventional management is not successful. Most neonates receiving ECMO suffer from meconium aspiration syndrome (MAS), congenital diaphragmatic hernia (CDH), sepsis or persistent pulmonary hypertension (PPH). In five-year-old children who underwent VA-ECMO therapy as neonates, we assessed motor performance related to growth, intelligence and behaviour, and the association with the primary diagnosis.

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.

Serotypes, genotypes, and antibiotic susceptibility profiles of group B streptococci causing neonatal sepsis and meningitis before and after introduction of antibiotic prophylaxis.

We studied the characteristics of strains isolated from neonates with group B streptococci sepsis and meningitis, before and after the introduction of antibiotic prophylaxis in The Netherlands. In 1999, 1 year after this introduction the serotype and genotype distribution and the susceptibility patterns of the GBS strains had not changed. Penicillins remain drugs of first choice to prevent and treat neonatal GBS disease.

Follow-up of newborns treated with extracorporeal membrane oxygenation: a nationwide evaluation at 5 years of age.

Introduction: Extracorporeal membrane oxygenation (ECMO) is a supportive cardiopulmonary bypass technique for babies with acute reversible cardiorespiratory failure. We assessed morbidity in ECMO survivors at the age of five years, when they start primary school and major decisions for their school careers must be made.

Methods: Five-year-old neonatal venoarterial-ECMO survivors from the two designated ECMO centres in The Netherlands (Erasmus MC--Sophia Children's Hospital in Rotterdam, and University Medical Center Nijmegen) were assessed within the framework of an extensive follow-up programme.

Neonatal group B streptococcal infection: incidence and strategies for prevention in Europe.

We sent a questionnaire to all members of the European Society for Paediatric Infectious Diseases and to all delegates of the European Association of Perinatal Medicine to determine existing policies for prevention of neonatal group B streptococcal (GBS) infection in Europe. The incidence of GBS colonization in pregnant women and of neonatal GBS infection varies. Policies for prevention of GBS infection are not well-developed.

Epidemiology of neonatal group B streptococcal disease in The Netherlands 1997-98.

Group B streptococcal (GBS) infection is still an important cause of morbidity and mortality in newborn infants. In The Netherlands, there are no published data on the incidence of neonatal GBS infection. We collected data of all infants with GBS disease during the first 3 months of life, as reported to the Dutch Paediatric Surveillance Unit (DPSU) during a period of 2 years (1997-98).
