Tocolysis after preterm prelabor rupture of membranes and 5-year outcomes: a population-based cohort study.

Background: The administration of tocolytics after preterm prelabor rupture of membranes remains a controversial practice. In theory, reducing uterine contractility should delay delivery and allow for optimal antenatal management, thereby reducing the risks for prematurity and adverse consequences over the life course. However, tocolysis may be associated with neonatal death or long-term adverse neurodevelopmental outcomes, mainly related to prolonged fetal exposure to intrauterine infection or inflammation.

Association of Chorioamnionitis with Cerebral Palsy at Two Years after Spontaneous Very Preterm Birth: The EPIPAGE-2 Cohort Study.

Objective: To assess whether chorioamnionitis is associated with cerebral palsy (CP) or death at 2 years' corrected age in infants born before 32 weeks of gestation after spontaneous birth.

Study Design: EPIPAGE-2 is a national, prospective, population-based cohort study of children born preterm in France in 2011; recruitment periods varied by gestational age. This analysis includes infants born alive after preterm labor or preterm premature rupture of membranes from 24 to 31 weeks of gestation.

Impact of Latency Duration on the Prognosis of Preterm Infants after Preterm Premature Rupture of Membranes at 24 to 32 Weeks' Gestation: A National Population-Based Cohort Study.

Objective: To assess the impact of latency duration on survival, survival without severe morbidity, and early-onset sepsis in infants born after preterm premature rupture of membranes (PPROM) at 24-32 weeks' gestation.

Study Design: This study was based on the prospective national population-based Etude Épidémiologique sur les Petits Ȃges Gestationnels 2 cohort of preterm births and included 702 singletons delivered in France after PPROM at 24-32 weeks' gestation. Latency duration was defined as the time from spontaneous rupture of membranes to delivery, divided into 4 periods (12 hours to 2 days [reference], 3-7 days, 8-14 days, and >14 days).

Ages and Stages Questionnaires: feasibility of postal surveys for child follow-up.

Background: The Ages and Stages Questionnaire (ASQ), completed by parents and caregivers, has been shown to be an accurate tool for screening children who need further developmental assessment.

Aims: To assess the feasibility of using the French Canadian translation of the ASQ in an epidemiological cohort of children from the French general population.

Study Design: Follow-up study by postal questionnaire at 12 and 36 months, using the ASQ.

Apgar scores reported in personal child health records: validity for epidemiological studies?

Aim: In epidemiological studies on children, information in the neonatal period that might affect children's long-term health could be extracted from the personal child health record (PCHR), because the booklet exists in most countries. We aimed to assess, in individual children, the validity of Apgar scores reported in the PCHR using maternity medical records as the gold standard.

Methods: In two French hospitals, 435 women who had a child in January 2006 were recruited and 90% filled in a postal questionnaire 6 weeks after delivery, copying neonatal information (including Apgar scores) from the PCHR.

[Exclusive and mixed breastfeeding in a maternity unit in France, 2003].

Purpose: To assess how exclusive and mixed breastfeeding varied depending on the characteristics of the mother, the newborn, and place of birth.

Methods: A national representative sample of births included 14,580 live births. During the hospital stay, mothers were asked if the infant was exclusively breastfed, breast and bottle-fed (mixed), or only bottle-fed.

Perinatal factors reported by mothers: do they agree with medical records?

As perinatal events have been linked with diseases of later onset, epidemiological studies on child development and adult health require information on the perinatal period. When national neonatal registers do not exist, review of medical records may be impractical. However, neonatal information could be obtained by asking mothers to complete a postal questionnaire using data from the Personal Child Health Record (PCHR).

Caesarean before labour between 34 and 37 weeks: what are the risk factors of severe neonatal respiratory distress?

Objective: To assess the frequency of severe neonatal respiratory distress and identify its risk factors in caesarean deliveries before labour between 34 and 37 weeks' gestation.

Study Design: Retrospective study of children born by caesarean delivery before labour between 34 and 37 weeks, between 1999 and 2003 in a level 3 maternity unit. The frequencies of severe and mild neonatal respiratory distress were calculated.
