Atosiban versus placebo in the treatment of threatened preterm birth between 30 and 34 weeks gestation: study protocol of the 4-year APOSTEL 8 follow-up.

Introduction: Currently, the majority of women worldwide with threatened preterm birth are treated with tocolytics. Although tocolytics can effectively delay birth for 48 hours, no tocolytic drug has convincingly been shown to improve neonatal outcomes and effects on long-term child development are unknown. The aim of this follow-up study of a placebo controlled randomised trial is to investigate the long-term effects of atosiban administration in case of threatened preterm birth on child's neurodevelopment and behaviour development, overall health and mortality.

Association between bronchopulmonary dysplasia severity and its risk factors and long-term outcomes in three definitions: a historical cohort study.

Objective: To compare the association of the severity categories of the 2001-National Institutes of Health (NIH), the 2018-NIH and the 2019-Jensen bronchopulmonary dysplasia (BPD) definitions with neurodevelopmental and respiratory outcomes at 2 and 5 years' corrected age (CA), and several BPD risk factors.

Design: Single-centre historical cohort study with retrospective data collection.

Setting: Infants born between 2009 and 2015 at the Amsterdam University Medical Centers, location Amsterdam Medical Center.

Effect of systemic hydrocortisone in ventilated preterm infants on parent-reported behavioural outcomes at 2 years' corrected age: follow-up of a randomised clinical trial.

Objective: To report the parent-reported behavioural outcomes of infants included in the Systemic Hydrocortisone To Prevent Bronchopulmonary Dysplasia in preterm infants study at 2 years' corrected age (CA).

Design: Randomised placebo-controlled trial.

Setting: Dutch and Belgian neonatal intensive care units.

Long-term follow-up of children exposed in-utero to progesterone treatment for prevention of preterm birth: study protocol of the AMPHIA follow-up.

Introduction: Preterm birth is one of the main problems in obstetrics, and the most important cause of neonatal mortality, morbidity and neurodevelopmental impairment. Multiple gestation is an important risk factor for preterm birth, with up to 50% delivering before 37 weeks. Progesterone has a role in maintaining pregnancy and is frequently prescribed to prevent (recurrent) preterm birth and improve pregnancy outcomes in high-risk patients.

Maternal, perinatal and childhood outcomes of the PPROMEXIL-III cohort: Pregnancies complicated by previable prelabor rupture of membranes.

Objective: Perinatal mortality after previable prelabor rupture of membranes (previable PROM) might be underestimated as most studies exclude patients with poor prognosis, or solely include patients in tertiary-care centers. We aimed to report perinatal, neonatal and long-term outcomes in a consecutive series of women with pregnancies complicated by previable PROM.

Study Design: We conducted a prospective cohort study including women with singleton pregnancies and previable PROM ≤ 23 weeks gestational age (GA) from one tertiary hospital and eight affiliated secondary hospitals in the region of Amsterdam, the Netherlands (June 2012 until January 2016, PPROMEXIL-III cohort).

Child outcomes after induction of labour or expectant management in women with preterm prelabour rupture of membranes between 34 and 37 weeks of gestation: study protocol of the PPROMEXIL Follow-up trial. A long-term follow-up study of the randomised controlled trials PPROMEXIL and PPROMEXIL-2.

Introduction: Late preterm prelabour rupture of membranes (PROM between 34 and 36 weeks gestational age) is an important clinical dilemma. Previously, two large Dutch randomised controlled trials (RCTs) compared induction of labour (IoL) to expectant management (EM). Both trials showed that early delivery does not reduce the risk of neonatal sepsis as compared with EM, although prematurity-related risks might increase.

Neurologic sequelae of severe chikungunya infection in the first 6 months of life: a prospective cohort study 24-months post-infection.

Background: Perinatally chikungunya infected neonates have been reported to have high rates of post-infection neurologic sequelae, mainly cognitive problems. In older children and adults chikungunya does not appear to have sequelae, but data on postnatally infected infants are lacking.

Methods: We performed a prospective, non-controlled, observational study of infants infected before the age of 6 months with a severe chikungunya infection during the 2014-2015 epidemic in Curaçao, Dutch Antilles.

Development and nationwide implementation of a postdischarge responsive parenting intervention program for very preterm born children: The TOP program.

A previous randomized controlled trial has suggested the effectiveness of a Dutch postdischarge responsive parenting program for very preterm (VPT) infants, indicating that nationwide implementation was justified. This paper describes the development and nationwide implementation of the intervention, known as the TOP program, which consisted of three phases. In the preparation phase (2006-2010), a theory of change and the structure of the TOP program were developed, and funding for phase two, based on a positive Business Case, was obtained.

Temporizing management vs immediate delivery in early-onset severe preeclampsia between 28 and 34 weeks of gestation (TOTEM study): An open-label randomized controlled trial.

Introduction: There is little evidence to guide the timing of delivery of women with early-onset severe preeclampsia. We hypothesize that immediate delivery is not inferior for neonatal outcome but reduces maternal complications compared with temporizing management.

Material And Methods: This Dutch multicenter open-label randomized clinical trial investigated non-inferiority for neonatal outcome of temporizing management as compared with immediate delivery (TOTEM NTR 2986) in women between 27 and 33 weeks of gestation admitted for early-onset severe preeclampsia with or without HELLP syndrome.

Progesterone for prevention of preterm birth in women with short cervical length: 2-year infant outcomes.

Objective: To evaluate the long-term outcomes of children born to women with a short cervix and otherwise low risk for preterm birth, after antenatal exposure to vaginal progesterone vs placebo.

Methods: This was a follow-up study of the Triple P trial, which randomized 80 low-risk women with a short cervix (≤ 30 mm) at 18-22 weeks' gestation to progesterone (n = 41) or placebo (n = 39). At 2 years of corrected age, children were invited for a neurodevelopmental assessment, using the Bayley Scales of Infant and Toddler Development, third edition (BSID-III), and a neurological and physical examination by an assessor blinded to the allocated treatment.

Executive function training in very preterm children: a randomized controlled trial.

Objective of the current study was to assess whether game-formatted executive function (EF) training, is effective in improving attention, EF and academic performance in very preterm and/or extremely low birthweight children aged 8-12 years. A multi-center, double-blind, placebo- and waitlist controlled randomized trial (NTR5365) in two academic hospitals in The Netherlands was performed. Eighty-five very preterm children with parent-rated attention problems on the Child Behavior Checklist were randomized to one of three treatment conditions: EF training, placebo training or waitlist condition.

Effects of tocolysis with nifedipine or atosiban on child outcome: follow-up of the APOSTEL III trial.

Objective: To compare the long-term effects of tocolysis with nifedipine or atosiban on child outcome at age 2.5-5.5 years.

Subtypes of behavioral functioning in 8-12 year old very preterm children.

Background: Very preterm children often have difficulties in behavioral functioning, but there is large heterogeneity in the severity of these difficulties and in the combination of the difficulties observed. Few studies so far addressed this heterogeneity by examining whether more homogeneous subtypes of behavioral functioning can be identified.

Aims: To identify behavioral subtypes in a group of very preterm children, examine whether such subtypes are related to neonatal medical complications and/or parental education level (to better understand origins) and to examine whether such subtypes are associated with IQ and neurocognitive deficits in attention and executive function (to study underlying mechanisms of dysfunction).

Child outcomes after amnioinfusion compared with no intervention in women with second-trimester rupture of membranes: a long-term follow-up study of the PROMEXIL-III trial.

Objective: To assess the effect of transabdominal amnioinfusion or no intervention on long-term outcomes in children born after second-trimester prelabour rupture of the membranes (PROM between 16 -24  weeks) and oligohydramnios.

Population: Follow up of infants of women who participated in the randomised controlled trial: PPROMEXIL-III (NTR3492).

Methods: Surviving infants were invited for neurodevelopmental assessment up to 5 years of corrected age using a Bayley Scales of Infant and Toddler Development or a Wechsler Preschool and Primary Scale of Intelligence.

Eight-year-old very and extremely preterm children showed more difficulties in performance intelligence than verbal intelligence.

Aim: This study determined possible discrepancies between verbal IQ and performance IQ in 8-year-old very preterm (VPT) and extremely preterm (EPT) children, and examined associations between verbal IQ and performance IQ, and sociodemographic factors, perinatal factors, early cognitive outcomes and also with school achievement scores.

Methods: This prospective cohort study included 120 eight-year-old VPT/EPT children. Cognitive development was assessed at the ages of 2, 5 and 8 years.

Effects of Executive Function Training on Attentional, Behavioral and Emotional Functioning and Self-Perceived Competence in Very Preterm Children: A Randomized Controlled Trial.

Objective: Very preterm children have poorer attentional, behavioral and emotional functioning than term-born children. Problems on these domains have been linked to poorer executive function (EF). This study examined effects of a game-formatted, comprehensive EF training on attentional, behavioral and emotional functioning and self-perceived competence in very preterm children.

Early-onset fetal growth restriction: A systematic review on mortality and morbidity.

Introduction: Severe early-onset fetal growth restriction is an obstetric condition with significant risks of perinatal mortality, major and minor neonatal morbidity, and long-term health sequelae. The prognosis of a fetus is influenced by the extent of prematurity and fetal weight. Clinical care is individually adjusted.

Postnatal Catch-Up Growth After Suspected Fetal Growth Restriction at Term.

The aim of this study was to study growth patterns of children born after suspected fetal growth restriction (FGR) at term and to compare the effect of induction of labor (IoL) and expectant management (EM), also in relation to neurodevelopmental and behavioral outcome at age 2. We performed a 2 years' follow-up of growth of children included in the Disproportionate Intrauterine Growth Restriction Trial at Term (DIGITAT) study, a Randomized Controlled Trial (RCT) comparing IoL with EM in pregnancies with suspected FGR at term. We collected data on child growth until the age of 2 years.

Developmental outcomes of very preterm children with high parental education level.

Background: Compared to their term-born peers, children born very preterm are at risk for poorer cognitive, academic and behavioral outcomes, however this finding may have been confounded by lower parental education level in the very preterm children. Studies that compare very preterm and term-born children with comparable (high) parental education level are needed to assess the true effect of very preterm birth on outcomes.

Aims: To compare cognitive, academic and behavioral functioning in very preterm and term-born children of highly educated parents.

Child outcomes after placement of a cervical pessary in women with a multiple pregnancy: A 4-year follow-up of the ProTWIN trial.

Introduction: The ProTWIN trial previously showed no beneficial effect of treatment with a cervical pessary vs usual care to prevent preterm birth in women with a multiple pregnancy. However, in women with a midtrimester short cervix (<38 mm), pessary did reduce the composite outcome of neonatal morbidity and mortality. This follow-up study evaluates the long-term outcomes of all children born to mothers who participated in the ProTWIN trial at 4 years of age.

Executive function deficits in children born preterm or at low birthweight: a meta-analysis.

Aim: To investigate the magnitude of executive function deficits and their dependency on gestational age, sex, age at assessment, and year of birth for children born preterm and/or at low birthweight.

Method: PubMed, PsychINFO, Web of Science, and ERIC were searched for studies reporting on executive functions in children born preterm/low birthweight and term controls born in 1990 and later, assessed at a mean age of 4 years or higher. Studies were included if five or more studies reported on the same executive function measures.

Psychosocial developmental trajectory of a cohort of young adults born very preterm and/or with a very low birth weight in the Netherlands.

Background: The achievement of age-specific developmental milestones in youth is of great importance to the adjustment in adult life. Young adults who were born preterm, might go through a different developmental trajectory and transition into adulthood than their peers. This study aimed to compare the psychosocial developmental trajectory of young adults who were born preterm with peers from the general population.

Neurodevelopmental outcomes at five years after early-onset fetal growth restriction: Analyses in a Dutch subgroup participating in a European management trial.

Objective: The objective of this study is to explore developmental outcomes at five years after early-onset fetal growth restriction (FGR).

Study Design: Retrospective data analysis of prospective follow-up of patients of three Dutch centres, who participated in a twenty centre European randomized controlled trial on timing of delivery in early-onset FGR. Developmental outcome of very preterm infants born after extreme FGR is assessed at (corrected) age of five.
