RESUMEN
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.

In France, the most pessimistic estimates put the prevalence of neurodevelopmental disorders (NDD) at 15 % of births. The two largest populations of newborns at highest risk of NDD are premature babies and babies born into siblings with one or more infants who already have an autism spectrum disorder or another NDD. The high prevalence of these disorders justifies a health promotion policy, centred on the child and his or her family. Prevention is based on the early identification of high-risk factors, by informing families and training pregnancy and early childhood professionals, and implementing perinatal prevention protocols for high-risk newborns (antenatal corticosteroid therapy and magnesium sulfate for women at risk of preterm delivery before 32 weeks, developmental care, therapeutic hypothermia for full-term infants with early neonatal encephalopathy presumed to be anoxic). Preventing the severity of NDD depends on their early identification, as early as possible in the highest plastic "1000 days" developmental window, a smooth flow of diagnosis and care for mothers and children, and the establishment of an ecosystem that includes multi-modal early intervention, at the best in multi-disciplinary teams such as the early medical and social action centres, support for families through guidance programs and inclusion in the community, first in day-care centers and then in nursery schools.

BACKGROUND: In recent years, there has been a wide array of research studies published on parental mental health and stress following very preterm birth. This review aims at reviewing the prevalence and risk factors of long-term parental depression, anxiety, post-traumatic stress symptoms and parenting stress following very preterm birth. METHODS: We searched PubMed, PsychINFO and Web of Science for descriptive, cross-sectional and longitudinal studies published between January 2013 and August 2022. RESULTS: 45 studies met our inclusion criteria. In the first two years, depression, anxiety, post-traumatic stress symptoms and parenting stress were present in â¼20 % of mothers of extreme and very low birth weight (E/VLBW) infants. Long-term psychological distress symptoms could be observed, although few studies have focused on symptoms into school age and longer. Fathers of VLBW infants might experience more psychological distress as well, however, they were only included in ten studies. We found that parental distress is more common when the co-parent is struggling with mental health symptoms. Many risk factors were identified such as social risk, history of mental illness, interpersonal factors (i.e. social support) and child-related factors (i.e. intraventricular hemorrhage, disability, use of medical equipment at home). LIMITATIONS: Several studies have methodological issues, such as a lack of control of known confounders and there is a large variety of measures employed. CONCLUSION: Important risk factors for stress and mental health symptoms were identified. More evidence is needed to determine if long-term symptoms persist into school age. Research should focus on taking a family-based approach in order to identify preventive strategies and resilience factors in parents of VLBW infants.

Background: Executive functions (EFs) are a set of neuropsychological skills permitting solving problems in a new situation by regulating action, behavior, and emotional response. As cerebral maturation remains vulnerable in preterm children, a higher risk of developing cognitive disorders including EFs exist compared to term children. Aims: The aim of this study was to estimate the incidence of preschool EF impairments through proxy reports in children born preterm before 34 weeks of gestational age using the Behavior Rating Inventory of Executive Function-Preschool (BRIEF-P) version. Secondary aims were to report neonatal, child, or socioeconomic factors associated with EF disorders. Results: Parents of 357 children born preterm aged 3-4â years old completed the BRIEF-P version. Impairment in EFs was clinically significant for 13.5% of preterm children (n = 47; 95% CI = 0.10-0.18) compared to 5.1% in term children. A low parental socioeconomic level was significantly associated with impaired parent-rated EF (19.1% vs. 5.3%, p = 0.003). Conclusions: Proxy reports of EF impairment are about twice as frequent as in term children. EF difficulties are not related to neonatal or child severity factors in contrast with the parental socioeconomic level. Using a parent-rated questionnaire may be a useful and easy tool to identify early the daily life impact of EF disorders on clinical follow-up of preterm children.This study was recorded in the Clinical Trials Register under identifier NCT03700463.
RESUMEN
BACKGROUND: Preterm-born children are at risk of behavioral disorders and the systematic assessment of these disorders remains a challenge. Questions remain about the accuracy of self-reported parent questionnaires and the real everyday life behavior of the child. AIM: To evaluate the association between SDQ reported by parents in the preterm and behavioral difficulties in the everyday school life environment reported by teacher. METHODS: All children born before 33 weeks and who followed-up in the LIFT (Loire Infant Follow-up team) network were included. The Strengths and Difficulties Parental Questionnaire (SDQ), completed at 5 years, was used to check for behavioral difficulties and identified three groups: "normal", "borderline" and "abnormal". Then, the SDQ results were compared to the Global School Adaptation Score (GSA) at 5 years. RESULTS: Out of the 1825 children followed in the cohort at the age of 5, 1397 questionnaires were analyzed. A total of 11.1% of children had an abnormal score, and 9.7% had a borderline score. Male gender and a lower birth weight z-score were significantly associated with the "abnormal SDQ" group. There is a significant relationship between the probability of being in the "abnormal SDQ" group at 5 years and with difficulty in global school adaptation at 5 years, as well as an SDQ borderline score in the preterm (p < 0.001). CONCLUSIONS: SDQ abnormal and borderline scores are associated with behavioral difficulties in the classroom and everyday life behavior. In preterm children, one should be alerted even by a borderline SDQ score.
RESUMEN
Objective: Assisted reproductive technology (ART) increases the rate of preterm births, though few studies have analyzed outcomes for these infants. No data are available on 4-year-old children born prematurely after ART. The objective was to investigate whether ART affect the neurodevelopmental outcomes at 4 years in preterm infants born before 34 weeks of gestational age (GA). Methods and results: A total of 166 ART and 679 naturally conceived preterm infants born before 34 weeks GA between 2013 and 2015 enrolled in the Loire Infant Follow-up Team were included. Neurodevelopment was assessed at 4 years using the age and stage questionnaire (ASQ) and the need for therapy services. The association between the socio-economic and perinatal characteristics and non-optimal neurodevelopment at 4â years was estimated. After adjustment, the ART preterm group remained significantly associated with a lower risk of having at least two domains in difficulty at ASQ: adjusted odds ratio (aOR) 0.34, 95% confidence interval (CI) (0.13-0.88), p = 0.027. The factors independently associated with non-optimal neurodevelopment at 4â years were male gender, low socio-economic level, and 25-30 weeks of GA at birth. The need for therapy services was similar between groups (p = 0.079). The long-term neurodevelopmental outcomes of preterm children born after ART are very similar, or even better than that of the spontaneously conceived children.
RESUMEN
Background: Preterm infants are at risk of neurodevelopmental impairments. At present, proton magnetic resonance spectroscopy (1H-MRS) is currently used to evaluate brain metabolites in asphyxiated term infants. The purpose of this study was to identify in the preterm EPIRMEX cohort any correlations between (1H-MRS) metabolites ratio at term equivalent age (TEA) and neurodevelopmental outcomes at 2 years. Methods: Our study included EPIRMEX eligible patients who were very preterm infants (gestational age at birth ≤32 weeks) and who underwent a brain MRI at TEA and 1H-MRS using a monovoxel technique. The volumes of interest (VOI) were periventricular white matter posterior area and basal ganglia. The ratio of N Acetyl Aspartate (NAA) to Cho (Choline), NAA to Cr (creatine), Cho to Cr, and Lac (Lactate) to Cr were measured. Neurodevelopment was assessed at 24 months TEA with ASQ (Ages and Stages Questionnaire). Results: A total of 69 very preterm infants had a 1H-MRS at TEA. In white matter there was a significant correlation between a reduction in the NAA/Cho ratio and a total ASQ and/or abnormal communication score, and an increase in the Lac/Cr ratio and an abnormality of fine motor skills. In the gray nuclei there was a trend correlation between the reduction in the NAA/Cho ratio and sociability disorders; and the increase in the Lac/Cr ratio and an anomaly in problem-solving. Conclusions: Using NAA as a biomarker, the vulnerability of immature oligodendrocytes in preterm children at TEA was correlated to neurodevelopment at 2 years. Similarly, the presence of lactate at TEA was associated with abnormal neurodevelopment at 2 years in the preterm brain.
RESUMEN
Context and purpose: Prematurity is a situation that can disrupt parent-child interactions. We hypothesize that establishing relationships with parents in a context of extreme prematurity can alter the development of secure attachment representations in the child. Furthermore, we hypothesize that secure maternal representations and their possible interactions with prematurity factors prevent the development of insecure or disorganized attachment in the child. In addition, maternal representations and their possible interactions with factors related to prematurity may prevent or accentuate the development of an insecure or disorganized attachment in the child. Methods and analysis: This is a longitudinal, prospective, exploratory, and bi-centric study. Children born in the neonatal intensive care units of Angers or Nantes University Hospitals with a gestational age of up to 28 weeks will be included in the study. The main objective is to describe the attachment representations at 3 and 5 years through the Attachment Story Completion Task scales and to analyze them in regard to the children's neurocognitive and behavioral outcomes as well as maternal attachment and mental health. Ethics: The study file received a favorable opinion for the implementation of this research on February 18, 2020 - ID-RCB no. 2019-A03352-55 (File 2-20-007 id6699) 2°HPS. This study has received authorization from the French Data Protection Authority (CNIL) under no. 920229. Discussion: A better understanding of attachment representations in extreme prematurity and their possible associations with children's neurocognitive and behavioral outcomes as well as maternal attachment and mental health could pave the way for individualized care at an early stage, or even interventions during the neonatal period to improve the outcome of these vulnerable newborns. Trial registration: [ClinicalTrials.gov], identifier [NCT04304846].
RESUMEN
This study's objective was to correlate the abnormalities in brain MRIs performed at corrected-term age for minor or moderate neurocognitive disorders in children school-age born extremely premature (EPT) and without serious sequelae such as autism, cerebral palsy, mental impairment. Data were issued from a cross-sectional multicenter study (GP-Qol study, number NCT01675726). Clinical examination and psychometric assessments were performed when the children were between 7 and 10 years old during a day-long evaluation. Term-equivalent age brain MRIs on EPT were analyzed with a standardized scoring system. There were 114 children included in the study. The mean age at the time of evaluation, was 8.47 years old (± 0.70). 59% of children with at least one cognitive impairment and 53% who had a dysexecutive disorder. Only ten EPT (8.7%) presented moderate to severe white and grey matter abnormalities. These moderate to severe grey matter abnormalities were associated with at least two abnormal executive functions [OR 3.08 (95% CI 1.04-8.79), p = 0.04] and language delay [OR 3.25 (95% CI 1.03-9.80), p = 0.04]. These results remained significant in the multivariate analysis. Moderate to severe ventricular dilatation abnormalities (15%, n = 17) were associated with ideomotor dyspraxia [OR 7.49 (95% CI 1.48-35.95), p = 0.02] and remained significant in multivariate analysis [OR 11.2 (95% CI 1.45-131.4), p = 0.02]. Biparietal corrected diameters were moderate abnormal in 20% of cases (n = 23) and were associated to visuo spatial integration delay [OR 4.13 (95% CI 1.23-13.63), p = 0.02]. Cerebral MRI at term-equivalent age with scoring system analysis can provide information on long-term neuropsychological outcomes at school-age in EPTs children having no severe disability.

OBJECTIVE: Previous studies have assessed breastfeeding-support programmes. Among these, osteopathic manipulative treatment (OMT) is a frequently used approach, although without strong evidence of efficacy. METHODS: A double-blind randomised controlled trial was conducted between July 2013 and March 2016. Breastfed term infants were eligible if one of the following criteria was met: suboptimal breastfeeding behaviour, maternal cracked nipples or maternal pain. The infants were randomly assigned to the intervention or the control group. The intervention consisted of two sessions of early OMT, while in the control group, the manipulations were performed on a doll behind a screen. The primary outcome was the exclusive breastfeeding rate at 1 month, which was assessed in an intention-to-treat analysis. Randomisation was computer generated and only accessible to the osteopath practitioner. The parents, research assistants and paediatricians were masked to group assignment. RESULTS: One hundred twenty-eight mother-infant dyads were randomised, with 64 assigned to each group. In each group, five infants were lost to follow-up. In the intervention group, 31 of 59 (53%) of infants were still exclusively breast fed at 1 month vs 39 of 59 (66%) in the control group, (OR 0.55, 95% CI 0.26 to 1.17; p=0.12). After adjustment for suboptimal breastfeeding behaviour, caesarean section, use of supplements and breast shields, the adjusted OR was 0.44 (95% CI 0.17 to 1.11; p=0.08). No adverse effects were reported in either group. CONCLUSION: OMT did not improve exclusive breast feeding at 1 month. TRIAL REGISTRATION NUMBER: NCT01890668.

OBJECTIVE: To assess the Global School Adaptation (GSA) questionnaire of children's abilities and classroom behavior administered to teachers of very preterm children at 5 years of age as a predictor of the need for educational support (grade retention, special class, learning support) at age 7. STUDY DESIGN: We assessed 858 very preterm children (<33 weeks of gestation) at 5 years of age using the GSA and again at 7 years to determine the use of educational support. We examined the association between the GSA score and educational support at 7 years and performed a receiver operating characteristic curve analysis. RESULTS: At 7 years of age, 130 children had educational support (15.2%). Children with a nonoptimal GSA score (<45) at 5 years required educational support more often (57.7%) than children with a GSA score of 45 or greater (15.4%) (OR, 7.5; 95% CI, 5.02-11.21). The need for educational support was associated with male sex; a low parent socioeconomic level; lower birth weight, birth head circumference, or gestational age (28-30 weeks of gestation); severe neurologic complications; patent ductus arteriosus ligation; and the use of therapy services at 5 years of age. After adjustment, only the GSA score was associated with educational support at 7 years of age (OR, 0.86; 95% CI, 0.84-0.88). A receiver operating characteristic curve analysis of the GSA performance revealed an optimal cut-off at 48, with a sensitivity of 70.8%, a specificity of 73.5%, and an area under the curve of 0.79. CONCLUSIONS: Using a cut-off score of 48, the GSA at 5 years of age may be a useful tool to identify children born preterm at risk of school-based learning difficulties.

BACKGROUND: We examined how specific cognitive behavioral impairments impacted quality of life (QoL) within a large multicenter cohort of 7-10 year olds surviving extremely preterm (EPT) without major neurodevelopmental disability. METHODS: Between 7 and 10 years of age, two generic, self-proxy, and parental evaluations were obtained. QoL measurement questionnaires (Kidscreen-10/VSPA (Vécu et Santé Perçue de l'Enfant et de l'Adolescent)) were used and compared to a reference population. The general and specific cognitive functions, such as executive functions, behavior and anxiety, and clinical neurologic examination, were also assessed. RESULTS: We analyzed 211 school-aged EPT children. The mean gestational age was 26.2 (±0.8) weeks, birth weight was 879 g (±181) and the mean age was 8.4 years (±0.87). Children with a Full-Scale Index Quotient ≥89, who were considered as normal, had a lower QoL. Specific cognitive impairments: comprehensive language delay, visuo-spatial integration defect, and dysexecutive disorders) were the QoL correlates in the domains of school performance and body image. CONCLUSIONS: School and health care professionals need to increase their focus on EPT children's lower so as to recognize the preterm behavioral/cognitive phenotype and their potential need for supportive measures. Research on preventive interventions is warranted to investigate if these long-term effects of an EPT birth can be attenuated in neonatal period and after.

OBJECTIVE: To determine the quality of life (QoL) of school-aged children who were born <28+0 weeks of gestation and who have no resultant major disabilities. DESIGN, SETTING AND PATIENTS: A cross-sectional multicentre study of extremely preterm (EPT) infants born <28+0 weeks, discharged alive and free from severe impairments (cerebral palsy, autism, major cognitive disabilities). Two generic, self-evaluation and hetero-evaluation (by parent) QoL measurement questionnaires (Kidscreen 10/VSP-A) were used and then compared with French population reference. MAIN OUTCOME MEASURES: Clinical examination, an assessment of cognitive functions and QoL between 7 and 10 years of age. RESULTS: 40 (7.5%) severely disabled children were excluded. Among those 471 eligible, the lost to follow-up group (169 (36%)) paralleled those 302 (64%) included in the study. The mean gestational age was 26.2 (±0.8), birth weight was 879 (±181) g and the mean age was 8.4 (±0.87) years. 48% of participants had minor or moderate cognitive disabilities based on their Full-Scale Index Quotient. Working memory, attention and mental flexibility scored as low-average. Except for family relationships, the EPT QoL VSP-A and Kidscreen 10 assessment were significantly lower based on the children's and parent's perspectives. Children reported the most significant QoL decline as (1) friends' relationships, (2) self-esteem and (3) leisure, while parents indicated (1) psychological well-being, (2) schoolwork and (3) vitality. CONCLUSION: The QoL of a school-age EPT child without severe impairment was lower relative to a reference population from both the parents' and child's points of view. This evaluation should help to better understand the long-term outcomes and to provide better support for them and their families. TRIAL REGISTRATION NUMBER: NCT01675726, pre-results.

BACKGROUND: To investigate the relative contributions of prenatal complications, perinatal characteristics, neonatal morbidities and socio-economic conditions on the occurrence of motor, sensory, cognitive, language and psychological disorders in a large longitudinal preterm infant population during the first 7 years after birth. METHODS: The study population comprised 4122 infants born at <35 weeks of gestation who were followed for an average of 74.0 months after birth. Developmental disorders, including motor, sensory, cognitive, language and psychological, were assessed at each follow-up visit from 18 months to 7 years of age. The investigated determinants included prenatal complications (prolonged rupture of membranes >24 hours, intrauterine growth restriction, preterm labour and maternal hypertension), perinatal characteristics (gender, multiple pregnancies, gestational age, birth weight, APGAR score and intubation or ventilation in the delivery room), neonatal complications (low weight gain during hospitalization, respiratory assistance, severe neurological anomalies, nosocomial infections) and socio-economic characteristics (socio-economic level, parental separation, urbanicity). Based on hazard ratios determined using a propensity score matching approach, population-attributable fractions (PAF) were calculated for each of the four types of determinants and for each developmental disorder. RESULTS: The percentages of motor, sensory, cognitive, language and psychological disorders were 17.0, 13.4, 29.1, 25.9 and 26.1%, respectively. The PAF for the perinatal characteristics were the highest and they were similar for the different developmental disorders considered (around 60%). For the neonatal and socio-economic determinants, the PAF varied according to the disorder, with contributions of up to 17% for motor and 27% for language disorders, respectively. Finally, prenatal complications had the lowest contributions (between 6 and 13%). CONCLUSIONS: This study illustrates the heterogeneity of risk factors on the risk of developmental disorder in preterm infants. These results suggest the importance of considering both medical and psycho-social follow-ups of preterm infants and their families.

The objective of this study was to quantify the possible decrease in school performance at five years of age in preterm children associated with parental separation or divorce, and to test whether this effect varies according to the child's age at the time of the separation. This study included 3,308 infants delivered at < 35 weeks of gestation born between 2003 and 2011 who were enrolled in the population-based LIFT cohort and who had an optimal neurodevelopmental outcome at two years of age. These infants were evaluated by their teachers to assess their abilities and behavior when they had reached five years of age, using the Global School Adaptation (GSA) questionnaire. The mean GSA score was 50.8 points. Parental separations (assessed as parents either living together or living separately) were associated with a decrease in school performance at five years of age, although this was only the case for children who exhibited difficulties at school (3.7 points, p < 0.01). A decrease in school performance only occurred when parental separations took place between 3 and 5 years after the child's birth. Parental separation was associated with a decrease in these children's levels of motivation, autonomy, and manual dexterity. This study indicates that preterm infants of parents who had separated are particularly at risk of a lower scholar performance.

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.

OBJECTIVE: The objective of this study was to investigate both the effects of low gestational age and infant's neurodevelopmental outcome at 2 years of age on the risk of parental separation within 7 years of giving birth. DESIGN: Prospective. SETTING: 24 maternity clinics in the Pays-de-la-Loire region. PARTICIPANTS: This study included 5732 infants delivered at <35 weeks of gestation born between 2005 and 2013 who were enrolled in the population-based Loire Infant Follow-up Team cohort and who had a neurodevelopmental evaluation at 2 years. This neurodevelopmental evaluation was based on a physical examination, a psychomotor evaluation and a parent-completed questionnaire. OUTCOME MEASURE: Risk of parental separation (parents living together or parents living separately). RESULTS: Ten percent (572/5732) of the parents reported having undergone separation during the follow-up period. A mediation analysis showed that low gestational age had no direct effect on the risk of parental separation. Moreover, a non-optimal neurodevelopment at 2 years was associated with an increased risk of parental separation corresponding to a HR=1.49(1.23 to 1.80). Finally, the increased risk of parental separation was aggravated by low socioeconomic conditions. CONCLUSIONS: The effect of low gestational age on the risk of parental separation was mediated by the infant's neurodevelopment.

Preterm infants present higher risk of non-optimal neurodevelopmental outcome. Fetal and postnatal growth, in particular head circumference (HC), is associated with neurodevelopmental outcome. OBJECTIVES: We aimed to calculate the relationship between HC at birth, HC delta Z-score (between birth and hospital discharge), and non-optimal neurodevelopmental outcome at 2 years of corrected age in preterm infants. METHODS: Surviving infants born ≤34 weeks of gestation were included in the analysis. The relationship between the risk of being non-optimal at 2 years and both HC at birth and HC growth was assessed. The 2 Z-scores were considered first independently and then simultaneously to investigate their effect on the risk of non-optimality using a generalized additive model. RESULTS: A total of 4,046 infants with both HC measures at birth and hospital discharge were included. Infants with small HC at birth (Z-score <-2 SD), or presenting suboptimal HC growth (dZ-score <-2 SD), are at higher risk of non-optimal neurodevelopmental outcome at 2 years (respectively OR 1.7 [95% CI 1.4-2] and OR 1.4 [95% CI 1.2-1.8]). Interestingly, patients cumulating small HC Z-score at birth (-2 SD) and presenting catch-down growth (HC dZ-score [-2 SD]) have a significantly increased risk for neurocognitive impairment (OR >2) while adjusting for gestational age, twin status, sex, and socioeconomic information. CONCLUSIONS: HC at birth and HC dZ-score between birth and hospital discharge are synergistically associated to neurodevelopmental outcome at 2 years of corrected age, in a population-based prospective cohort of preterm infants born ≤34 weeks of gestation.

OBJECTIVE: To assess genetic mutations and associated somatic anomalies in a series of patients with 46,XY gonadal dysgenesis (GD). DESIGN: Single center retrospective study. SETTING: University pediatric hospital. PATIENT(S): Fourteen patients with 46,XY GD. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Genotype-phenotype relationship. RESULT(S): The presenting symptom was disorders of sex development (6 patients), primary amenorrhea (2 patients), discordance between 46,XY karyotype and female external genitalia (3 patients), discovery of Müllerian structures at surgery (2 patients), or diagnosed in the evaluation of a gonadal tumor (1 patient). Müllerian structures were shown by ultrasound evaluation in 7 of 13 patients, genitography in 3 of 6 patients and/or surgery in 8 of 10 patients (3 not seen at imaging), or only by histologic examination (1 patient). Three patients had gonadoblastoma and/or seminoma. A mutation was found in 7 patients of whom 2 had family history of reproductive problems and 5 had associated somatic anomalies. The mutations were FOG2/ZFPM2 (1 patient), SRY (2 patients), WT1 (1 patient), or deletions of distal chromosome 9p (3 patients). Among the three other patients with associated anomalies and no mutation, two had ectodermal dysplasia and one had leukemia. CONCLUSION(S): Mutations were observed in half of the patients with 46,XY GD with Müllerian structures. We also describe for the first time the association between GD and ectodermal dysplasia. Müllerian structures can be found in some cases only by histologic examination, which should be coupled to preventive gonadectomy because of the risk of tumor formation.

BACKGROUND: Preterm infants are at greater risk of developmental impairment and require close follow-up for early and optimal care. OBJECTIVES: The objective of the present study was to determine from which age the parental Ages and Stages Questionnaire (ASQ) allows detection of school difficulties in preterm children <35 weeks' gestational age. METHODS: Preterm children from the regional Loire Infant Follow-up Team network were evaluated with the Global School Adaptation (GSA) assessment tool at 5 years of age and at least one parental-completed ASQ at 18, 24, or 36 months. Children belonging to the first decile of the GSA score (<38) were considered to have severe school difficulties. Using overall ASQ scores as continuous variables, receiver operating characteristic (ROC) curves were generated at every age in order to identify preterm children with severe school difficulties. RESULTS: GSA scores were obtained in 1,775 infants at 5 years of age, and at least one ASQ score at 18, 24, or 36 months was completed. Upon ROC analysis, we observed that the 18-, 24-, and 36-month ASQ scores produced respective area under the ROC curve values of 0.66 (0.64-0.69), 0.72 (0.70-0.75), and 0.77 (0.75-0.80) for predicting a GSA score in the first decile. An ASQ cutoff value of 255 at 36 months showed optimal discriminatory power for identifying significant school difficulties at 5 years of age. CONCLUSIONS: The 36-month ASQ is a simple and cost-effective tool that can be employed to help predict future severe school difficulties at 5 years of age in preterm-born children.
