Objectives To describe neurodevelopmental outcomes at 2 years corrected age for children born alive at 22-26, 27-31, and 32-34 weeks’ gestation in 2011, and to evaluate changes since ...1997.Design Population based cohort studies, EPIPAGE and EPIPAGE-2.Setting France.Participants 5567 neonates born alive in 2011 at 22-34 completed weeks’ gestation, with 4199 survivors at 2 years corrected age included in follow-up. Comparison of outcomes reported for 3334 (1997) and 2418 (2011) neonates born alive in the nine regions participating in both studies.Main outcome measures Survival; cerebral palsy (2000 European consensus definition); scores below threshold on the neurodevelopmental Ages and Stages Questionnaire (ASQ; at least one of five domains below threshold) if completed between 22 and 26 months corrected age, in children without cerebral palsy, blindness, or deafness; and survival without severe or moderate neuromotor or sensory disabilities (cerebral palsy with Gross Motor Function Classification System levels 2-5, unilateral or bilateral blindness or deafness). Results are given as percentage of outcome measures with 95% confidence intervals.Results Among 5170 liveborn neonates with parental consent, survival at 2 years corrected age was 51.7% (95% confidence interval 48.6% to 54.7%) at 22-26 weeks’ gestation, 93.1% (92.1% to 94.0%) at 27-31 weeks’ gestation, and 98.6% (97.8% to 99.2%) at 32-34 weeks’ gestation. Only one infant born at 22-23 weeks survived. Data on cerebral palsy were available for 3599 infants (81.0% of the eligible population). The overall rate of cerebral palsy at 24-26, 27-31, and 32-34 weeks’ gestation was 6.9% (4.7% to 9.6%), 4.3% (3.5% to 5.2%), and 1.0% (0.5% to 1.9%), respectively. Responses to the ASQ were analysed for 2506 children (56.4% of the eligible population). The proportion of children with an ASQ result below threshold at 24-26, 27-31, and 32-34 weeks’ gestation were 50.2% (44.5% to 55.8%), 40.7% (38.3% to 43.2%), and 36.2% (32.4% to 40.1%), respectively. Survival without severe or moderate neuromotor or sensory disabilities among live births increased between 1997 and 2011, from 45.5% (39.2% to 51.8%) to 62.3% (57.1% to 67.5%) at 25-26 weeks’ gestation, but no change was observed at 22-24 weeks’ gestation. At 32-34 weeks’ gestation, there was a non-statistically significant increase in survival without severe or moderate neuromotor or sensory disabilities (P=0.61), but the proportion of survivors with cerebral palsy declined (P=0.01).Conclusions In this large cohort of preterm infants, rates of survival and survival without severe or moderate neuromotor or sensory disabilities have increased during the past two decades, but these children remain at high risk of developmental delay.
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. We constituted 4 groups based on whether the infant was suspected with fetal growth restriction during pregnancy and/or was small for gestational age with a birthweight <10th percentile of intrauterine norms by sex: 1) suspected with fetal growth restriction/small for gestational age 2) not suspected with fetal growth restriction/small for gestational age 3) suspected with fetal growth restriction/not small for gestational age and 4) not suspected with fetal growth restriction/not small for gestational age. We estimated relative risks of perinatal mortality and morbidity for these groups adjusting for maternal and neonatal characteristics. Results We found that 22.2% of infants were suspected with fetal growth restriction/small for gestational age, that 11.4% infants were not suspected with fetal growth restriction/small for gestational age, that 3.0% infants were suspected with fetal growth restriction/not small for gestational age, and that 63.4% infants were not suspected with fetal growth restriction/not small for gestational age. Compared with infants who were not suspected with fetal growth restriction/not small-for-gestational-age infants, small-for-gestational-age infants suspected and not suspected with fetal growth restriction had higher risks of stillbirth or termination of pregnancy (adjusted relative risk, 2.0 95% confidence interval, 1.6–2.5 and adjusted relative risk, 2.8 95% confidence interval, 2.2–3.4, respectively), in-hospital death (adjusted relative risk, 2.8 95% confidence interval, 2.0–3.7 and adjusted relative risk, 2.0 95% confidence interval, 1.5–2.8, respectively), and bronchopulmonary dysplasia (adjusted relative risk, 1.3 95% confidence interval, 1.2–1.4 and adjusted relative risk, 1.3 95% confidence interval, 1.1–1.4, respectively), but not severe brain lesions. Risks were not increased for infants suspected with fetal growth restriction but not small-for-gestational-age. Conclusion Antenatal and postnatal assessments of fetal growth restriction were not concordant for 14% of very preterm infants. In these cases, birthweight appears to be the more relevant parameter for the identification of infants with higher risks of adverse short-term outcomes.
To investigate the association of the cause of preterm birth on in-hospital mortality of preterm neonates born from 24 to 34 weeks of gestation.
L'Etude épidémiologique sur les petits âges ...gestationnels (EPIPAGE)-2 is a prospective, nationwide, population-based cohort of very preterm births. After dividing causes of preterm birth into six mutually exclusive groups, we analyzed the association of each cause with in-hospital deaths of preterm neonates born alive with adjustment for organizational, maternal, and obstetric factors.
The analysis included 3,138 singleton live births from 24 to 34 weeks of gestation with a newborn in-hospital mortality rate of 5.0% (95% confidence interval 4.5-5.7). Preterm labor was the most frequent cause of preterm birth (n=1,293 43.5%) followed by preterm premature rupture of membranes (n=765 23.9%), hypertensive disorders without suspected fetal growth restriction (n=397 12.7%), hypertensive disorders with suspected fetal growth restriction (n=408 10.9%), placental abruption after an uncomplicated pregnancy (n=92 3.0%), and suspected fetal growth restriction without hypertensive disorders (n=183 5.9%). Neonates born because of suspected fetal growth restriction with or without hypertensive disorders (adjusted odds ratio OR 3.0 1.9-4.7 and adjusted OR 2.3 1.1-4.6, respectively) had higher adjusted risks of in-hospital death than those born after preterm labor. Risks of in-hospital mortality for preterm births caused by preterm premature rupture of membranes (adjusted OR 1.3 0.9-1.9), hypertensive disorders without fetal growth restriction (adjusted OR 0.7 0.4-1.4), or placental abruption (adjusted OR 1.6 0.7-3.7) were similar to those born after preterm labor.
Among neonates born alive before 34 weeks of gestation, only those born because of suspected fetal growth restriction have a higher mortality risk than those born after preterm labor.
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). Multivariable logistic regression was used to assess the relationship between latency duration and survival, survival without severe morbidity at discharge, or early-onset sepsis. Results Latency duration ranged from 12 hours to 2 days (18%), 3-7 days (38%), 8-14 days (24%), and >14 days (20%). Rates of survival, survival without severe morbidity, and early-onset sepsis were 93.5% (95% CI 91.8-94.8), 85.4% (82.4-87.9), and 3.4% (2.0-5.7), respectively. A crude association found between prolonged latency duration and improved survival disappeared on adjusting for gestational age at birth (aOR 1.0 reference, 1.6 95% CI 0.8-3.2, 1.2 0.5-2.9, and 1.0 0.3-3.2 for latency durations from 12 hours to 2 days, 3-7 days, 8-14 days, and >14 days, respectively). Prolonged latency duration was not associated with survival without severe morbidity or early-onset sepsis. Conclusion For a given gestational age at birth, prolonged latency duration after PPROM does not worsen neonatal prognosis.
To investigate the relationship between placenta-mediated pregnancy complications and bronchopulmonary dysplasia (BPD) in very preterm infants.
National prospective population-based cohort study ...including 2697 singletons born before 32 weeks' gestation. The main outcome measure was moderate to severe BPD. Three groups of placenta-mediated pregnancy complications were compared with no placenta-mediated complications: maternal disorders only (gestational hypertension or preeclampsia), fetal disorders only (antenatal growth restriction), and both maternal and fetal disorders.
Moderate to severe BPD rates were 8% in infants from pregnancies with maternal disorders, 15% from both maternal and fetal disorders, 23% from fetal disorders only, and 9% in the control group (P < .001). When we adjusted for gestational age, the risk of moderate to severe BPD was greater in the groups with fetal disorders only (odds ratio OR = 6.6; 95% confidence interval CI, 4.1-10.7), with maternal and fetal disorders (OR = 3.7; 95% CI, 2.5-5.5), and with maternal disorders only (OR = 1.7; 95% CI, 1.0-2.7) than in the control group. When we also controlled for birth weight, the relationship remained in groups with fetal disorders only (OR = 4.2; 95% CI, 2.1-8.6) and with maternal and fetal disorders (OR = 2.1; 95% CI, 1.1-3.9).
Placenta-mediated pregnancy complications with fetal consequences are associated with moderate to severe BPD in very preterm infants independently of gestational age and birth weight, but isolated maternal hypertensive disorders are not. Fetal growth restriction, more than birth weight, could predispose to impaired lung development.
The principal aim was to investigate the feasibility of assessing mother-infant interactions at discharge and at 6 months infant corrected age in singletons born before 32 weeks of gestation. The ...secondary aims were to describe these interactions and their disorders, explore the association between maternal emotional state and the interactions, and assess the relationship between disordered interactions and infant social withdrawal behaviour.
OLIMPE is an ancillary study of the population-based study EPIPAGE 2, which recruited preterm neonates in France in 2011. 163 dyads participated at discharge and 148 at 6 months. Interactions were observed with the Attachment During Stress (ADS) scale, which includes two behavioural subscales, for the mother (m-ADS) and her infant (i-ADS). Two professionals independently completed the ADS scales for one third of the observations. Maternal emotional state was assessed using self-administered questionnaires of depression, anxiety, and stress. Infant's social withdrawal behaviour at 6 months was measured by the Alarm Distress Baby scale.
At discharge, 15.3% of the m-ADS scales and 43.3% of the i-ADS scales had at least one unobserved component. At 6 months, all items on both scales were noticeable in >90% of the dyads. Reliability, estimated by the kappa coefficient, ranged between 0.39 and 0.76 at discharge, and between 0.21 and 0.69 at 6 months. Disordered interactions were indicated on 48.6% of the m-ADS scales and 36.5% of the i-ADS scales at discharge. At 6 months, these rates were 32.6% and 26.0%. Disordered interactions at 6 months were associated with identified disorder at discharge. Insecure infant attachment was not influenced by maternal mental health but was strongly associated with infant social withdrawal behaviour.
The ADS scale can be used to screen for early interaction disorders after premature birth and may help to target dyads that would most benefit from early intervention.

It has been demonstrated that universal hearing neonatal screening (UHNS) is efficient at providing early diagnosis and rehabilitation for deafness. The risk factors of deafness in children have been ...identified, but less specifically in those diagnosed after UHNS. In this study, we aim to study these factors in infants who were referred after screening and to compare our experience to recent data. We studied infants referred to our department for diagnosis after screening between January 2018 and December 2021. Their medical history and neonatal hearing risk factors were assessed. Associations between factors were also analyzed. Sixty-six infants were included. A family history of deafness (47%), syndromic deafness (41%), intrauterine growth retardation or prematurity (19.7%), and prolonged NICU admission (18%) were the most observed factors. When analyzing according to these associations, family history of deafness and syndromic cases remained the most prevalent factors (74%), while only five cases (7.8%) presented with other neonatal risk factors only. The majority of congenital hearing loss cases are observed in infants with suspected genetic deafness. Parental counseling, the diagnostic pathway, as well as the healthcare system should be adapted according to these risk factors.
Aim
This study compared neurodevelopmental screening questionnaires completed when preterm‐born children reached 2 years of corrected age with social communication skills at 5.5 years of age.
Methods
...Eligible subjects were born in 2011 at 24–34 weeks of gestation, participated in a French population‐based epidemiological study and were free of motor and sensory impairment at 2 years of corrected age. The Ages and Stages Questionnaire (ASQ) and the Modified Checklist for Autism in Toddlers (M‐CHAT) were used at 2 years and the Social Communication Questionnaire (SCQ) at 5.5 years of age.
Results
We focused on 2119 children. At 2 years of corrected age, the M‐CHAT showed autistic traits in 20.7%, 18.5% and 18.2% of the children born at 24–26, 27–31 and 32–34 weeks of gestation, respectively (p = 0.7). At 5.5 years of age, 12.6%, 12.7% and 9.6% risked social communication difficulties, with an SCQ score ≥90th percentile (p = 0.2). A positive M‐CHAT score at 2 years was associated with higher risks of social communication difficulties at 5.5 years of age (odds ratio 3.46, 95% confidence interval 2.04–5.86, p < 0.001). Stratifying ASQ scores produced similar results.
Conclusion
Using parental neurodevelopmental screening questionnaires for preterm‐born children helped to identify the risk of later social communication difficulties.
The aim of this study was to compare the effectiveness of a hand-held preoperative compact imager (POCI) camera with conventional lymphoscintigraphy using a γ-camera for sentinel lymph node (SLN) ...detection in breast cancer.
The main objective was to demonstrate the noninferiority of the POCI relative to conventional lymphoscintigraphy and to compare the number of SLNs detected by the 2 imaging devices. Our study, a clinical prospective, double-blind, noninferiority study, planned to include 200 patients with early breast cancer and started in January 2006. A standard SLN protocol (4 periareolar injections of 37 MBq of (99m)Tc-nanocolloids, 2 h before lymphoscintigraphy) was performed preoperatively using a conventional γ-camera and then the POCI camera. Scans were obtained by 2 different nuclear medicine physicians unaware of each other's results. The day after, in the operating room, the surgeon, after receiving the previous results, used the counting probe for surgical SLN biopsy. The number and localization of axillary SLNs obtained by lymphoscintigraphy and the POCI and the duration of the whole procedure were determined.
Among the 162 patients included, 138 were evaluable. The POCI detected more SLNs than did lymphoscintigraphy in 50 patients (36%), the same number of in 54 patients (39%), and fewer SLNs in 34 patients (25%), representing 84 (61%) discordant pairs. The noninferiority of preoperative compact imaging of axillary SLNs numbers was found to be statistically significant (95% confidence interval, 30%-52%, P = 0.025) using the McNemar test. The duration of acquisition was shorter using the POCI (<10 min in 84% n = 117 of patients; mean, 7.5 ± 3.3 min) than lymphoscintigraphy (13% n = 18 of patients; mean, 15.7 ± 3.4 min), with P < 0.001 using the McNemar test for paired proportions.
Preoperative compact imaging using a hand-held camera was able to predict the number and localization of breast cancer SLNs and was not inferior to conventional lymphoscintigraphy in this study. Further studies will determine whether preoperative compact imaging could replace lymphoscintigraphy, especially in surgical centers without an on-site nuclear medicine department.

Placenta-mediated pregnancy complications with fetal consequences are associated with moderate to severe BPD in very preterm infants independently of gestational age and birth weight, but isolated maternal hypertensive disorders are not. Fetal growth restriction, more than birth weight, could predispose to impaired lung development.
