Clinical Chorioamnionitis and Neurodevelopment at 5 Years of Age in Children Born Preterm: The EPIPAGE-2 Cohort Study.

Objective: To assess the association between clinical chorioamnionitis and neurodevelopmental disorders at 5 years of age in children born preterm.

Study Design: EPIPAGE 2 is a national, population-based cohort study of children born before 35 weeks of gestation in France in 2011. We included infants born alive between 24 and 34 weeks after preterm labor or preterm premature rupture of membranes.

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.

Cognitive Training for Visuospatial Processing in Children Aged 5½ to 6 Years Born Very Preterm With Working Memory Dysfunction: A Randomized Clinical Trial.

Importance: Compared with term-born peers, children born very preterm generally perform poorly in executive functions, particularly in working memory and inhibition. By taking advantage of neuroplasticity, computerized cognitive training of working memory in those children could improve visuospatial processing by boosting visual inhibition via working memory.

Objective: To evaluate the long-term effect of cognitive working memory training on visuospatial processing in children aged 5½ to 6 years born very preterm who have working memory impairment.

Five-year outcomes for extremely preterm babies with active perinatal management: A clinical prediction model.

Objective: To develop and validate a clinical prediction model for outcomes at 5 years of age for children born extremely preterm and receiving active perinatal management.

Design: The EPIPAGE-2 national prospective cohort.

Setting: France, 2011.

Circumstances, causes and timing of death in extremely preterm infants admitted to NICU: The EPIPAGE-2 study.

Aim: To describe the circumstances, causes and timing of death in extremely preterm infants.

Methods: We included from the EPIPAGE-2 study infants born at 24-26 weeks in 2011 admitted to neonatal intensive care units (NICU). Vital status and circumstances of death were used to define three groups of infants: alive at discharge, death with or without withholding or withdrawing life-sustaining treatment (WWLST).

Chorionicity and neurodevelopmental outcomes at 5½ years among twins born preterm: the EPIPAGE2 cohort study.

Objective: To compare the neurodevelopmental outcomes of preterm twins at 5½ years by chorionicity of pregnancy.

Design: Prospective nationwide population-based EPIPAGE2 (Etude Epidémiologique sur les Petits Âges Gestationnels) cohort study.

Setting: A total of 546 maternity units in France, between March and December 2011.

Early skin-to-skin contact and risk of late-onset-sepsis in very and extremely preterm infants.

Background: To evaluate the association between exposure to early skin-to-skin contact (SSC) and incidence of late-onset sepsis (LOS) in extremely and very preterm infants.

Methods: Observational study using the national population-based EPIPAGE-2 cohort in 2011. A propensity score for SSC exposure was used to match infants with and without exposure to SSC before day 4 of life and binomial log regression used to estimate risk ratios and CIs in the matched cohort.

Early-onset neonatal sepsis in the Paris area: a population-based surveillance study from 2019 to 2021.

Background: Early-onset neonatal sepsis (EOS) is a rare condition but an important cause of severe morbidity and mortality in neonates.

Methods: This is a prospective observational study in neonates born at ≥34 weeks of gestation (WG). The primary endpoint was EOS, defined by isolation of pathogenic species from blood culture and/or cerebrospinal fluid culture within 72 hours after birth.

Neurodevelopment at 5 years of age for preterm-born children according to mode of conception: a cohort study.

Background: Preterm delivery is a risk factor for suboptimal neurodevelopment. Pregnancies conceived after medically assisted reproduction-which includes in vitro fertilization, with or without intracytoplasmic insemination, and induction of ovulation followed by intrauterine insemination or timed intercourse-have a higher risk of preterm delivery. Few studies have evaluated the outcome at >2 years of age of such preterm-born children.

Risk factors for hypoxic-ischemic encephalopathy in cases of severe acidosis: A case-control study.

Introduction: The aim of the study was to identify the obstetric risk factors for hypoxic-ischemic encephalopathy (HIE) in infants with asphyxia at birth.

Material And Methods: This multicenter case-control study covered the 5-year period from 2014 through 2018 and included newborns ≥36 weeks of gestation with an umbilical pH at birth ≤7.0.

A Case of Scrotoschisis with Exteriorization of Both Testes.

Scrotoschisis is a congenital malformation characterized by testicular exstrophy through a scrotal defect. We report a full-term baby boy with exteriorization of both testes through a right parietal scrotal defect. Bilateral testes extrusion through a lateralized scrotoschisis can occur due to a scrotal septal defect.

Antibiotic prophylaxis in preterm premature rupture of membranes at 24-31 weeks' gestation: Perinatal and 2-year outcomes in the EPIPAGE-2 cohort.

Objective: To compare different antibiotic prophylaxis administered after preterm premature rupture of membranes to determine whether any were associated with differences in obstetric and/or neonatal outcomes and/or neurodevelopmental outcomes at 2 years of corrected age.

Design: Prospective, nationwide, population-based EPIPAGE-2 cohort study of preterm infants.

Setting: France, 2011.

Early Antibiotic Exposure and Adverse Outcomes in Very Preterm Infants at Low Risk of Early-Onset Sepsis: The EPIPAGE-2 Cohort Study.

Objective: To assess the association between early empirical antibiotics and neonatal adverse outcomes in very preterm infants without risk factors for early-onset sepsis (EOS).

Study Design: This is a secondary analysis of the EPIPAGE-2 study, a prospective national population-based cohort that included all liveborn infants at 22-31 completed weeks of gestation in France in 2011. Infants at high risk of EOS (ie, born after preterm labor or preterm premature rupture of membranes or from a mother who had clinical chorioamnionitis or had received antibiotics during the last 72 hours) were excluded.

Perinatal outcome and need of care for term asphyxiated newborns without moderate or severe hypoxic-ischemic encephalopathy.

Aim: Birth asphyxia can lead to organ dysfunction, varying from isolated biological acidosis to hypoxic-ischemic encephalopathy (HIE). Pathophysiology of moderate or severe HIE is now well known and guidelines exist regarding the care required in this situation. However, for newborns without moderate or severe HIE, no consensus is available.

Birth outcomes between 22 and 26 weeks' gestation in national population-based cohorts from Sweden, England and France.

Aim: We investigated the timing of survival differences and effects on morbidity for foetuses alive at maternal admission to hospital delivered at 22 to 26 weeks' gestational age (GA).

Methods: Data from the EXPRESS (Sweden, 2004-07), EPICure-2 (England, 2006) and EPIPAGE-2 (France, 2011) cohorts were harmonised. Survival, stratified by GA, was analysed to 112 days using Kaplan-Meier analyses and Cox regression adjusted for population and pregnancy characteristics; neonatal morbidities, survival to discharge and follow-up and outcomes at 2-3 years of age were compared.

Predicting the risk of infant mortality for newborns operated for congenital heart defects: A population-based cohort (EPICARD) study of two post-operative predictive scores.

Background: Whereas no global severity score exists for congenital heart defects (CHD), risk (Risk Adjusted Cardiac Heart Surgery-1: RACHS-1) and/or complexity (Aristotle Basic Complexity: ABC) scores have been developed for those who undergo surgery. Population-based studies for assessing the predictive ability of these scores are lacking.

Objective: To assess the predictive ability of RACHS-1 and ABC scores for the risk of infant mortality using population-based cohort (EPICARD) data for newborns with structural CHD.

Cause of preterm birth and late-onset sepsis in very preterm infants: the EPIPAGE-2 cohort study.

Background: The pathogenesis of late-onset sepsis (LOS) in preterm infants is poorly understood and knowledge about risk factors, especially prenatal risk factors, is limited. This study aimed to assess the association between the cause of preterm birth and LOS in very preterm infants.

Methods: 2052 very preterm singletons from a national population-based cohort study alive at 72 h of life were included.

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.

Prenatal parental involvement in decision for delivery room management at 22-26 weeks of gestation in France - The EPIPAGE-2 Cohort Study.

Objective: Our main objective was to examine if parental prenatal preferences predict delivery-room management of extremely preterm periviable infants. The secondary objectives were to describe parental involvement and the content of prenatal counseling given to parents for this prenatal decision.

Design: Prospective study of neonates liveborn between 22 and 26 weeks of gestation in France in 2011 among the neonates included in the EPIPAGE-2 study.

Intensity of perinatal care, extreme prematurity and sensorimotor outcome at 2 years corrected age: evidence from the EPIPAGE-2 cohort study.

Background: Emerging evidence suggests intensity of perinatal care influences survival for extremely preterm babies. We evaluated the effect of differences in perinatal care intensity between centres on sensorimotor morbidity at 2 years of age. We hypothesised that hospitals with a higher intensity of perinatal care would have improved survival without increased disability.

Neonatal Outcomes in Extremely Preterm Newborns Admitted to Intensive Care after No Active Antenatal Management: A Population-Based Cohort Study.

Objective: To evaluate the association between active antenatal management and neonatal outcomes in extremely preterm newborns admitted to a neonatal intensive care unit (NICU).

Study Design: This population-based cohort study was conducted in 25 regions of France. Infants born in 2011 between 22 and 26 weeks of gestation and admitted to a NICU were included.

Preterm premature rupture of membranes at 22-25 weeks' gestation: perinatal and 2-year outcomes within a national population-based study (EPIPAGE-2).

Background: Most clinical guidelines state that with early preterm premature rupture of membranes, obstetric and pediatric teams must share a realistic and individualized appraisal of neonatal outcomes with parents and consider their wishes for all decisions. However, we currently lack reliable and relevant data, according to gestational age at rupture of membranes, to adequately counsel parents during pregnancy and to reflect on our policies of care at these extreme gestational ages.

Objective: We sought to describe both perinatal and 2-year outcomes of preterm infants born after preterm premature rupture of membranes at 22-25 weeks' gestation.
