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.

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.

Objectives : 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.Methods : 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.Results : 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.Conclusions : 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.

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.

ObjectiveTo report neurodevelopment at age 5.5 years according to developmental delay screening with the Ages & Stages Questionnaire (ASQ) in late infancy in preterm-born children.DesignPopulation-based cohort study, EPIPAGE-2.SettingFrance, 2011–2017.Participants2504 children born at 24–26, 27–31 and 32–34 weeks, free of cerebral palsy, deafness or blindness at 2 years’ corrected age.Main outcome measuresModerate/severe, mild or no disability at age 5.5 years using gross and fine motor, sensory, cognitive and behavioural evaluations. Results of the ASQ completed between 22 and 26 months’ corrected age described as positive screening or not.ResultsAmong 2504 participants, 38.3% had ASQ positive screening. The probability of having moderate/severe or mild disability was higher for children with ASQ positive versus negative screening: 14.2% vs 7.0%, adjusted OR 2.5 (95% CI 1.8 to 3.4), and 37.6% vs 29.7%, adjusted OR 1.5 (1.2 to 1.9). For children with ASQ positive screening, the probability of having neurodevelopmental disabilities at age 5.5 years was associated with the number of domain scores below threshold, very low gestational age and severe neonatal morbidities. For children with ASQ negative screening, this probability was increased for boys and children born small-for-gestational age. For both groups, maternal level of education was strongly associated with outcomes.ConclusionIn preterm-born children, ASQ screening at 2 years’ corrected age was associated with neurodevelopmental disabilities at age 5.5 years. However, other factors should be considered when interpreting the ASQ data to draw further follow-up.Trial registration number2016-A00333-48.

PurposeThe SEV-IDF programme aims to track infants born before 33 weeks of gestation, with very low birth weight (VLBW), neonatal encephalopathy or severe birth anomalies and perinatal disease. It employs an open, prospective, multicentric, population-based cohort approach. This report aims to describe the methodology employed to establish and manage the programme, details regarding follow-up procedures, baseline characteristics of the included infants, and highlights new research opportunities emerging from the \"Suivi des Enfants Vulnérables d'Ile-de-France\" (SEV-IDF) programme.ParticipantsThe programme aims to (1) detect developmental anomalies early, (2) improve prevention using standardised data, (3) optimise follow-up care and (4) support multidisciplinary research.Eligible participants are infants alive at discharge from the 59 maternities with a neonatal unit of the Île-de-France (IDF) region (France). A network of 567 trained physicians monitors the children’s development at 4 months, 1 and 2 years of corrected age, and 3, 4, 5, 6 and 7 years of age. Collected data include sociodemographic, pregnancy and neonatal characteristics, and standardised child development scores.Findings to dateThe programme enrolled 21 175 participants between 2016 and 2023, with 16 461 (77.7%) having a gestational age less than 33 weeks, 1916 (9.0%) others having VLBW, 1525 (7.2%) having encephalopathy and 1273 (6.0%) having another severe birth anomaly.Future plansThe collected data will enable the SEV-IDF scientific committee to describe high-risk infants in the IDF region, design evidence-based campaigns to improve the quality and effectiveness of the follow-up as well as conduct research on developmental anomalies in these high-risk infants. Ongoing research currently focuses on anticipating loss to follow-up and early detection of developmental anomalies.

[PUBLICATION ABSTRACT]

Background Children born at low gestational ages face a range of risks and number of neonates surviving very preterm birth is increasing. We present the objectives and methods of a French national cohort of very and moderately preterm children, the EPIPAGE 2 study. It aims to examine short- and long-term outcomes of very preterm children and their determinants. Methods/Design Eligible participants for this prospective population-based study include all infants live born or stillborn and all terminations of pregnancy between 22 and 31 completed weeks of gestation in all the maternity units in 25 French regions. In addition, a sample of moderate preterm births, i.e. births and late terminations at 32–34 weeks, was included in the same regions. In all, 7804 babies (stillbirths and live births) and terminations of pregnancy out of 8400 eligible births in France in 2011 that were either very (22–31 weeks) or moderately preterm (32–34 weeks) were included. Data on pregnancy, delivery, and neonatal events were extracted from the obstetric and neonatal records. The follow-up will collect information at corrected ages of one and 2 years and at 5, 8, and 12 years of age. Of the 4467 children discharged alive from the hospital and eligible for follow-up, 155 (4%) families refused further follow-up and 22 died before one-year of age. Finally, 4290 were included in the follow-up. Eight additional projects investigating specific hypotheses among subsamples of the cohort by collecting specific data in addition to the core cohort data are being conducted to investigate 1) diagnosis of histologic chorioamnionitis, 2) early biomarkers of child health, 3) attitudes of care for extremely preterm infants, 4) painful procedures in neonatal intensive care units, 5) neonatal MRI cerebral abnormalities and their relation to executive functions, 6) associations between early gut colonization and early and late onset diseases, 7) impact of neonatal nutrition on child development, and 8) mother-infant attachment. Discussion This project seeks to provide new data on the prognosis and etiology of very preterm birth and to assess related medical practices. Accordingly, it should lead to the development of new strategies of management and prevention in high-risk babies.

In contrast to the many reports of successful real-world cases of personalized bacteriophage therapy (BT), randomized controlled trials of non-personalized bacteriophage products have not produced the expected results. Here we present the outcomes of a retrospective observational analysis of the first 100 consecutive cases of personalized BT of difficult-to-treat infections facilitated by a Belgian consortium in 35 hospitals, 29 cities and 12 countries during the period from 1 January 2008 to 30 April 2022. We assessed how often personalized BT produced a positive clinical outcome (general efficacy) and performed a regression analysis to identify functional relationships. The most common indications were lower respiratory tract, skin and soft tissue, and bone infections, and involved combinations of 26 bacteriophages and 6 defined bacteriophage cocktails, individually selected and sometimes pre-adapted to target the causative bacterial pathogens. Clinical improvement and eradication of the targeted bacteria were reported for 77.2% and 61.3% of infections, respectively. In our dataset of 100 cases, eradication was 70% less probable when no concomitant antibiotics were used (odds ratio = 0.3; 95% confidence interval = 0.127–0.749). In vivo selection of bacteriophage resistance and in vitro bacteriophage–antibiotic synergy were documented in 43.8% (7/16 patients) and 90% (9/10) of evaluated patients, respectively. We observed a combination of antibiotic re-sensitization and reduced virulence in bacteriophage-resistant bacterial isolates that emerged during BT. Bacteriophage immune neutralization was observed in 38.5% (5/13) of screened patients. Fifteen adverse events were reported, including seven non-serious adverse drug reactions suspected to be linked to BT. While our analysis is limited by the uncontrolled nature of these data, it indicates that BT can be effective in combination with antibiotics and can inform the design of future controlled clinical trials. BT100 study, ClinicalTrials.gov registration: NCT05498363 . Analysis of 100 consecutive personalized bacteriophage therapy cases supports the use of personalized and sometimes pre-adapted, bacteriophage preparations, often in combination with antibiotics.
