Health outcomes of children with Prader-Willi or Angelman syndromes: a European population-based multicentre study.

Background/aim: Prader-Willi syndrome (PWS) and Angelman syndrome (AS) are rare imprinting disorders caused by the aberrant expression of 15q11.2-q13 imprinted genes. Due to their rarity, data on health outcomes during infancy are limited.

Postpartum maternal thrombophilia workup value in pregnancies with severe small for gestational age.

Introduction: In the absence of prenatal etiology explaining small for gestational age (SGA), a blood workup may be performed postpartum to look for maternal thrombophilia if a newborn is confirmed to be growth-restricted at birth. The literature regarding thrombophilia factors and fetal growth restriction is discordant. The main objective was to assess the prevalence and type of maternal thrombophilia among women delivering newborns of birthweight below the 3rd percentile and undergoing a postpartum thrombophilia workup and placental analysis.

Antiretroviral drug exposure in pregnancy and risk of congenital anomalies: a European case/non-case malformed study.

Purpose: Antiretroviral drugs are recommended during pregnancy to achieve HIV viral suppression and reduce mother-to-child transmission. Congenital anomaly signals were reported after fetal exposure to antiretroviral drugs in several studies warranting further investigation. We aimed to evaluate the risk of congenital anomalies after fetal exposure to antiretroviral drugs using the European congenital anomaly registry data.

Fetal Therapy for Congenital Pulmonary Malformations: A Prospective Population-Based National Cohort Study.

Objective: To assess the frequency of fetal therapy for fetuses with congenital pulmonary malformations (CPMs) and to investigate their short-term outcomes.

Method: The study population included 435 singleton fetuses diagnosed with CPMs from a national population-based cohort study in France in 2015-2018. Information was obtained from medical records on CPM volume ratio (CVR), signs of compression, fetal therapy and perinatal outcomes.

Growth charts for use at birth and in the neonatal period: Recommendations of the French Neonatal Society.

Introduction: The use of different growth charts can lead to confusion in discussions between professionals. There are obstetric charts (of fetal growth) and neonatal charts (of measurements at birth and of postnatal growth). These charts can be descriptive (derived from an unselected population) or prescriptive (derived from of a population at low risk and with optimal conditions for growth).

Validity of a Delphi consensus definition of growth restriction in the newborn for identifying neonatal morbidity.

Background: Small for gestational age is defined as a birthweight below a birthweight percentile threshold, usually the 10th percentile, with the third or fifth percentile used to identify severe small for gestational age. Small for gestational age is used as a proxy for growth restriction in the newborn, but small-for-gestational-age newborns can be physiologically small and healthy. In addition, this definition excludes growth-restricted newborns who have weights more than the 10th percentile.

Neurodevelopmental outcomes of preterm and growth-restricted neonate with congenital heart defect: a systematic review and meta-analysis.

Unlabelled: The purpose of the study is to assess the risks of neurodevelopmental morbidity among preterm and growth restricted youth with congenital heart defects (CHD). This systematic review and meta-analysis included observational studies assessing neurodevelopmental outcomes among children with CHD born preterm (i.e.

Which fetal growth charts should be used in France? Position of the French College of Obstetricians and Gynecologists (CNGOF).

Objective: To assess which fetal growth charts best describe intrauterine growth in France defined as the ability to classify 10% of fetuses below the 10th percentile (small for gestational age [SGA]) and above the 90th percentile (large for gestational age [LGA]) in the second and third trimesters.

Methods: We analyzed five studies on fetal ultrasound measurements using three French data sources. Two studies used second and third trimester ultrasound data from a nationwide birth cohort in 2011 (the ELFE study, N = 13 197 and N = 7747); one study used third trimester ultrasound data from on a nationwide cross-sectional study (the 2016 French National Perinatal Survey, N = 9940); and the last two studies were from the "Flash study" 2014 which prospectively collected ultrasound data from routine visits in the second and third trimesters (N = 4858 and N = 3522).

Postnatal diagnosis of congenital anomalies despite active systematic prenatal screening policies: a population-based registry study.

Background: Prenatal screening for congenital anomalies is an important component of maternity care, with continual advances in screening technology. However, few recent studies have investigated the overall effectiveness of a systematic policy of prenatal screening for congenital anomalies, such as in France where an ultrasound per trimester is recommended for all pregnant individuals.

Objective: This study aimed to assess the proportion and the type of congenital anomalies that are not detected during pregnancy.

Serial plotting of symphysis-fundal height and estimated fetal weight to improve the antenatal detection of infants small for gestational age: A cluster randomised trial.

Objective: To assess whether standardised longitudinal reporting of growth monitoring information improves antenatal detection of infants who are small for gestational age (SGA), compared with usual care.

Design: Cluster-randomised controlled trial.

Setting: Sixteen French level-3 units in 2018-2019.

Perinatal survival among very preterm singletons born after detection of early-onset fetal growth restriction with or without maternal hypertensive disorders: A population-based study in France.

Objective: To investigate the management and survival of very preterm singletons born because of fetal growth restriction (FGR) with or without maternal hypertensive disorders in France.

Study Design: From a population-based cohort of very preterm births between 22 and 31 weeks in France in 2011, the study population included all non-anomalous singleton pregnancies delivered because of detected FGR with or without maternal hypertensive disorders. Antenatal detection of FGR was defined as an estimated fetal weight <10th percentile with or without fetal Doppler abnormalities or growth arrest.

Testing the assumptions of customized intrauterine growth charts using national birth studies.

Introduction: Customized intrauterine growth charts are widely used for growth monitoring and research. They are based on three assumptions: (1) estimated fetal weight (EFW) has a normal distribution with a constant coefficient of variation at all gestational ages; (2) Hadlock's growth curve accurately describes the relation between EFW and gestational ages; (3) associations between EFW and the fetal and maternal characteristics included in the customization model (fetal sex, pre-pregnancy weight, height, parity) are proportional throughout pregnancy. The aim of this study was to test whether these underlying assumptions are verified.

World Health Organization fetal growth charts applied in a French birth cohort.

Objective: To evaluate the applicability of World Health Organization (WHO) fetal growth charts for abdominal circumference (AC), femur length (FL) and estimated fetal weight (EFW) at the second and third trimester ultrasounds in a French birth cohort.

Materials And Methods: Using the ELFE cohort of live births after 33 weeks' gestation in France in 2011, we selected 7747 singletons with fetal biometric measurements at the second (20-25 weeks) and third (30-35 weeks) trimester routine ultrasounds. We calculated proportions of fetuses <3rd and <10th percentiles and >90th and >97th percentiles for AC, FL and EFW using WHO charts and two international (Intergrowth and Hadlock) and two national (Salomon and CFEF) charts.

Unisex vs sex-specific estimated fetal weight charts for fetal growth monitoring: a population-based study.

Background: In contrast with birthweight or other growth charts, a feature of most intrauterine charts is that they are not differentiated by sex. Differences in weight by sex during pregnancy are considered to be relatively minor; however, small systematic differences may affect the sensitivity and specificity of screening for fetuses with growth restriction.

Objective: To assess differences between unisex and sex-specific estimated fetal weight charts at the third-trimester ultrasound with regard to the sex ratio of fetuses detected with an estimated fetal weight <10th percentile and subsequent detection of small-for-gestational-age newborns with morbidity at birth.

Indications leading to termination of pregnancy between 22 and 31 weeks of gestational age in France: A population-based cohort study.

Objective: To estimate the prevalence and indications of terminations of pregnancy (TOP) between 22 and 31 weeks of gestational age in France and to examine the characteristics of women by indication of TOP.

Study Design: From the EPIPAGE 2 population-based cohort study of preterm births in France in 2011, we selected 5009 singleton live births, stillbirths and TOP that occurred between 22 and 31 weeks. We estimated the proportion of TOP by gestational age.

Comparison of the Hadlock and INTERGROWTH formulas for calculating estimated fetal weight in a preterm population in France.

Background: Accurate estimation of fetal weight is needed for growth monitoring and decision-making in obstetrics; the INTERGROWTH project developed an estimated fetal weight formula to construct new intrauterine growth standards.

Objective: We sought to compare the accuracy of the Hadlock and INTERGROWTH formulas for the estimation of fetal weight among preterm infants.

Study Design: Using the EPIPAGE 2 population-based study of births between 22-34 weeks of gestation, we included 578 nonanomalous singleton fetuses with an ultrasound-to-delivery interval <2 days.

Fetal and neonatal outcomes of preterm infants born before 32 weeks of gestation according to antenatal vs postnatal assessments of restricted growth.

Background: Fetal growth restriction is defined using ultrasound parameters during pregnancy or as a low birthweight for gestational age after birth, but these definitions are not always concordant.

Objective: The purpose of this study was to investigate fetal and neonatal outcomes based on antenatal vs postnatal assessments of growth restriction.

Study Design: From the EPIPAGE 2 population-based prospective study of very preterm births in France in 2011, we included 2919 singleton nonanomalous infants 24-31 weeks gestational age.
