The role of perinatal palliative care following prenatal diagnosis of major, incurable fetal anomalies: a multicentre prospective cohort study.

OBJECTIVE: To describe prenatal decision-making processes and birth plans in pregnancies amenable to planning perinatal palliative care. DESIGN: Multicentre prospective observational study. SETTING: Nine Multidisciplinary Centres for Prenatal Diagnosis of the Paris-Ile-de-France region. POPULATION: All cases of major and incurable fetal anomaly eligible for TOP where limitation of life-sustaining treatments for the neonate was discussed in the prenatal period between 2015 and 2016. METHODS: Cases of congenital defects amenable to perinatal palliative care were prospectively included in each centre. Prenatal diagnosis, decision-making process, type of birth plan, birth characteristics, pregnancy and neonatal outcome were collected prospectively and anonymously. MAIN OUTCOME MEASURE: Final decision reached following discussions in the antenatal period. RESULTS: We identified 736 continuing pregnancies with a diagnosis of a severe fetal condition eligible for TOP. Perinatal palliative care was considered in 102/736 (13.9%) pregnancies (106 infants); discussions were multidisciplinary in 99/106 (93.4%) cases. Prenatal birth plans involved life-sustaining treatment limitation and comfort care in 73/736 (9.9%) of the pregnancies. The main reason for planning palliative care at birth was short-term inevitable death in 39 cases (53.4%). In all, 76/106 (71.7%) infants were born alive, and 18/106 (17%) infants were alive at last follow-up, including four with a perinatal palliative care birth plan. CONCLUSIONS: Only a small proportion of severe and incurable fetal disorders were potentially amenable to limitation of life-sustaining interventions. Perinatal palliative care may not be considered a universal alternative to termination of pregnancy. TWEETABLE ABSTRACT: Perinatal palliative care is planned in 10% of continuing pregnancies with a major and incurable fetal condition eligible for TOP.

Prenatal factors associated with neonatal survival of infants with congenital chylothorax.

OBJECTIVES: Congenital chylothorax is a rare disease and prognostic factors are key element in properly informing parents. This study aimed at determining the prenatal factors associated with neonatal survival in a cohort of liveborn infants with congenital chylothorax. STUDY DESIGN: Observational monocentric cohort study including all liveborn neonates consecutively admitted for congenital chylothorax. RESULTS: Neonatal mortality was 32% (16/50). Prematurity (or birth weight), persistence of hydrops at birth and the absence of thoracoamniotic shunt procedure were significantly associated with mortality, whereas prenatal diagnosis of pleural effusion, side of pleural effusion, hydrops fetalis and amniodrainage were not. In case of prenatal diagnosis of hydrops fetalis, the reversal in utero of hydrops fetalis was significantly associated with survival (P=0.001). In case of thoracoamniotic shunting, the interval between thoracoamniotic shunting intervention and delivery was significantly longer for patients who survived (P=0.03). CONCLUSIONS: Thoracoamniotic shunting and reversal of hydrops significantly improves survival, whereas prematurity worsened outcome of liveborn infants with congenital chylothorax. Our data also suggest that the interval between thoracoamniotic shunting and birth appears to be crucial; the longer the interval, the more likely is the reversal of antenatal hydrops and neonatal survival.

[About twins: Epidemiological, genetic, and obstetrical aspects, specific risks, and outcome]. / Le monde des jumeaux : aspects épidémiologiques et génétiques, enjeux obstétricaux, risques spécifiques et devenir.

The incidence of twin pregnancies has increased steadily for the last 40 years due to assisted reproductive technology and increased maternal childbearing age. Multiple pregnancies, especially monochorionic twin pregnancies, carry a high risk for the mother and the fetuses and require close follow-up. Twins are exposed to a higher risk of perinatal anoxia, in utero fetal demise, preterm birth, congenital malformations, fetal growth restriction, and vascular complications. Compared to singletons, twins are at higher risk of perinatal mortality and impaired neurodevelopmental outcome, justifying a thorough follow-up by pediatricians, including assessment and management of familial and psychosocial impact. This paper discusses the epidemiological, obstetrical, and genetic issues raised by twin pregnancies and reviews the data on the perinatal and neurological long-term outcomes of twins, as well as the psychosocial impact of multiple births on twins and their families.

[Epidemiology and pathophysiology of retinopathy of prematurity]. / Épidémiologie et physiopathologie de la rétinopathie du prématuré

Retinopathy of prematurity (ROP) is a major cause of visual impairment in premature infants. It is characterized by an arrest in normal retinal vascular development associated with microvascular degeneration, followed by an abnormal hypoxiainduced neovascularization. Recent studies point out that ROP is a multifactorial disease, implicating both oxygen-dependent and oxygen-independent mechanisms. Oxygen-dependent factors leading to microvascular degeneration include generation of reactive oxygen species and suppression of specific oxygen-regulated vascular survival factors, such as vascular endothelial growth factor (VEGF) and erythropoietin. The other major mechanism for the initial capillary loss is oxygen-independent and implicates a deficit in growth factor IGF-1/IGFBP3. The proliferative, second phase of ROP is triggered by increases in vascular growth factors concentrations, in an attempt to compensate for the hypoxic retina. Novel signaling pathways for vascular repair, implicating both metabolite signaling and inflammatory lipids signaling, represent new therapeutic avenues for ROP.

[Use of standardized parenteral solutions in French neonatal departments: results of a national survey]. / Utilisation des solutés standard pour l'alimentation parentérale du nouveau-né en France--Résultats d'une enquête nationale.

UNLABELLED: Standard parenteral nutrition solutions have been developed nationwide in France but little is known about their frequency of use and indications. OBJECTIVES: To evaluate the frequency of the use of standardized parenteral nutrition solutions in neonatal units in France, to determine which solutions are currently available and used, and to determine whether the available parenteral nutrition solutions are satisfactory to the prescriber by evaluating the type and number of additions most frequently prescribed. METHOD: National survey performed in France, using a questionnaire sent to 296 French neonatal departments. RESULTS: Eighty-five percent of level III units and 50% of the level II units responded to the questionnaire. Standardized parenteral nutrition solutions were used in 66% of the responding units and accounted for 45% of the prescriptions of parenteral nutrition in newborns. They were significantly more frequently prescribed by level II than level III units (68% vs. 24%, p<0.0001). Thirteen of the 40 standard solutions declared as solutions for parenteral nutrition did not contain amino acids. The addition of macro- and/or micronutrients was very frequent and often made even if not indicated in the Consumer Medicine Information (CMI). CONCLUSION: There is great heterogeneity in parenteral nutrition practices among French neonatal units. A large number of the standard solutions used are not appropriate for the nutrition of full-term and/or preterm infants. Their use in everyday practice does not cover the nutritional needs of the newborn or induces at-risk practices such as supplementation with macro- and/or micronutrients.

Early individualised parenteral nutrition for preterm infants.

Considerable effort should be made to optimise parenteral nutrition of preterm infants in order to limit the development of postnatal growth restriction. A monocentric before-and-after study design was used to determine the effects of computerising parenteral nutrition ordering on the composition of parenteral nutrition (PN) solutions and early clinical outcomes of preterm infants born < or =28 weeks of gestation. Parenteral protein intake during the first week of life and parenteral lipid, glucose and energy intakes during the first and second week of life were significantly higher in infants assessed after the introduction of computerised parenteral nutrition ordering. This led to a significant reduction in the cumulative energy deficit over the first 28 days of life and to an improvement in both early growth and pulmonary outcome. Computerising the PN ordering process improves the nutrient content of the PN solutions and early postnatal outcome.
