Aim: Since 2005, the French Food Safety Agency has recommended that very preterm or low-birthweight babies should be fed with pasteurised, expressed breastmilk, and feeding policies on this vary widely in French neonatal units. We investigated the differences between using a mother's expressed milk, in fresh or pasteurised forms, for very preterm infants.Methods: This observational multicentre study analysed data on 926 very preterm infants: 636 from neonatal units who used the mother's own fresh milk and 290 who used the mother's milk after pasteurisation. We analysed necrotising enterocolitis, bronchopulmonary dysplasia, in-hospital mortality, late-onset sepsis, weight gain, length of hospital stay, the duration of parenteral nutrition and the duration of enteral feeding with a nasogastric tube. Multivariate analyses were conducted to assess the impact of maternal milk policies.Results: After adjustment, there was a reduced risk of bronchopulmonary dysplasia in the fresh milk group with an odds ratio of 0.40 and 95% confidence interval of 0.27-0.67 (p < 0.001). No other statistically significant differences were observed.Conclusion: Feeding very preterm infants with their mother's expressed fresh milk was associated with a reduced risk of bronchopulmonary dysplasia, and further investigations are needed to evaluate the clinical impact of this practice.

This study was undertaken to assess one of the determinants of kidney concentrating capacity, aquaporin-2 (AQP2), in order to understand the physiopathology of water balance in newborn babies. Urinary AQP2 excretion has been shown to be proportional to AQP2 level in the apical plasma membrane of the kidney collecting ducts and has been suggested as a marker of vasopressin (AVP) action. Urinary AQP2 excretion in the early postnatal period and at 3 weeks of age was measured in 123 neonates admitted during a 6-month period to the neonatal intensive care unit of the Children’s Hospital of Toulouse, France. Clinical and biochemical data were collected for each child. During the first days after birth, higher urinary AQP2 was observed in boys than in girls ( P=0.01) and positively correlated with urinary sodium/potassium (Na/K) ratio (r=0.33, P=0.01). When the babies had reached 3 weeks of age, urinary AQP2 was proportional to the gestational age at birth (r=0.33, P=0.0068) and daily weight gain (r=0.36, P=0.003). It did not correlate with urinary osmolality, which was overall very low in all babies. Urinary AQP2 was decreased in conditions of impaired renal function (r=−0.42, P=0.0005) and acidosis ( P=0.03). Prenatal corticosteroid treatment had no significant impact on urinary AQP2 level. Our data show that urinary AQP2 correlates with the overall maturity of tubular function in human neonates. In babies at this early age, urinary AQP2 cannot serve as a direct marker of the renal action of AVP but reflects AQP2 expression level associated with different physiopathological conditions.

Objective: To describe the morbidity and mortality and long-term neurodevelopmental outcomes in children born from a Twin-to-Twin Transfusion Syndrome (TTTS) pregnancy treated using laser fetoscopy in Toulouse., Population and Method: All pregnancies with TTTS treated by laser fetoscopy in our centre were included. Antenatal and postnatal morbidity and neonatal morbidity were identified in the medical records retrospectively. The neurodevelopmental outcome was studied using Ages and Stages Questionnaires (ASQ) sent to the parents, an oral interview with the parents and with the child's doctor (last objective neurological examination, rehabilitation needs, learning disabilities)., Results: Seventy-one pregnancies, or 144 foetuses, were included from 2008 to 2014, overall survival at 2 years was 72.9% and the survival of at least one child at 2 years was 91.5%, severe neonatal morbidity was 11.2% of the children, severe brain damage accounted for 3.6% of children admitted to the hospital unit. It was possible to study the neurodevelopmental outcome for 58 children (55.3%), with a corrected age from 24 to 95 months. Five children (8.6%) had severe neurological abnormalities and 17 (29.3%) had moderate neurological abnormalities., Discussion: The mortality, neonatal morbidity and long-term neurological morbidity of our cohort are higher than those of premature infants (EPIPAGE-2 French cohort), which confirms the severity of this syndrome, and are comparable to those of the TTTS cohorts described in the literature., (Copyright © 2018 Elsevier Masson SAS.

Objectives: We compared the frequency of behavioral problems in very preterm and term children at 5 years of age. We hypothesized that behavioral problems would be associated with cognitive impairment and environmental factors and that differences between the 2 groups would be reduced but persist after adjusting for cognitive performance and environmental factors., Patients and Methods: The Etude Epidémiologique sur les Petits Ages Gestationnels (EPIPAGE) study was a prospective population-based cohort study that included all births occurring between 22 and 32 weeks' gestation and a control group of infants born at 39 to 40 weeks' gestation in 1997 in 9 French regions. Neonatal and obstetrics data were collected at birth. At 5 years of age, sociodemographic status and neurodevelopmental and cognitive development of the children, as well as maternal mental well-being, were assessed. The behavioral problems of 1102 very preterm and 375 term singletons without major impairments were studied by using the parent-completed Strengths and Difficulties Questionnaire., Results: Parents of very preterm children reported significantly more behavioral problems, with a twofold higher prevalence compared with term children for hyperactivity/inattention, emotional symptoms, and peer problems. Behavioral problems were associated with low cognitive performance, developmental delay, hospitalizations of the child, young maternal age, and poor maternal mental well-being. Very preterm children were still at higher risk of behavioral problems compared with term children after adjustment for cognitive performance and all others factors., Conclusions: Behavioral problems were strongly related to cognitive impairment, but very preterm children were still at higher risk even after adjusting for cognitive performance. Early screening for behavioral problems should be encouraged for all very preterm children, and maternal well-being should also be the focus of special attention.
