Descriptive analysis of infant population younger than 1 year admitted for BRUE.

INTRODUCTION: In 2016, the American Academy of Pediatrics defined the brief resolved unexplained event (BRUE) of high and low risk to characterize fainting in infants under 1 year of age. In the case of low-risk BRUE, it is recommended to perform no further systematic examination, but to monitor the child with a saturometer in the emergency room for 1-4 h. OBJECTIVE: The objective of this study was to identify events corresponding to high- and low-risk BRUE criteria for infants admitted to the Angers University Hospital Center, and to analyze their medical care. METHOD: We conducted an observational, retrospective, descriptive and single-center study of the population of infants younger than 1 year admitted for an unexplained event to the Pediatric Emergency Department of Angers University Hospital Center between 1 January 2017 and 31 December 2019. Two patient databases were crossed to identify patients. RESULTS: Among the 203 patients presenting for fainting, 54 patients met the criteria for BRUE, including 40 high-risk BRUE and 14 low-risk BRUE cases. All complementary examinations performed on low-risk BRUE children were normal. Two of these patients had a recurrence of non-severe fainting several months after the first episode. CONCLUSION: Identification of infants according to the BRUE criteria helps to harmonize practices and to limit the number of complementary examinations or hospitalizations for low-risk BRUE.

[Ante- and postnatal growth charts in France - guidelines for clinical practice from the Collège national des gynécologues et obstétriciens français (CNGOF) and from the Société française de néonatologie (SFN)]. / Les courbes de croissance anté- et postnatales en France ­ recommandations pour la pratique clinique du Collège national des gynécologues et obstétriciens français (CNGOF) et de la Société française de néonatologie (SFN).

OBJECTIVE: To recommend the most appropriate biometric charts for the detection of antenatal growth abnormalities and postnatal growth surveillance. METHODS: Elaboration of specific questions and selection of experts by the organizing committee to answer these questions; analysis of the literature by experts and drafting conclusions by assigning a recommendation (strong or weak) and a quality of evidence (high, moderate, low, very low) and for each question; all these recommendations have been subject to multidisciplinary external review (obstetrician gynecologists, pediatricians). The objective for the reviewers was to verify the completeness of the literature review, to verify the levels of evidence established and the consistency and applicability of the resulting recommendations. The overall review of the literature, quality of evidence and recommendations were revised to take into consideration comments from external reviewers. RESULTS: Antenatally, it is recommended to use all WHO fetal growth charts for EFW and common ultrasound biometric measurements (strong recommendation; low quality of evidence). Indeed, in comparison with other prescriptive curves and descriptive curves, the WHO prescriptive charts show better performance for the screening of SGA (Small for Gestational Age) and LGA (Large for Gestational Age) with adequate proportions of fetuses screened at extreme percentiles in the French population. It also has the advantages of having EFW charts by sex and biometric parameters obtained from the same perspective cohort of women screened by qualified sonographers who measured the biometric parameters according to international standards. Postnatally, it is recommended to use the updated Fenton charts for the assessment of birth measurements and for growth monitoring in preterm infants (strong recommendation; moderate quality of evidence) and for the assessment of birth measurements in term newborn (expert opinion). CONCLUSION: It is recommended to use WHO fetal growth charts for antenatal growth monitoring and Fenton charts for the newborn.

[Prolonged and post-term pregnancies: a regional survey of French clinical practices]. / Évaluation des pratiques professionnelles pour le suivi des grossesses prolongées dans un réseau de périnatalité.

OBJECTIVE: To assess professional practices of prolonged and post-term pregnancies in accordance to French guidelines. The secondary outcome was to evaluate neonatal and maternal morbidity during prolonged pregnancy. METHODS: Descriptive retrospective study was conducted in the 23 maternity hospitals of perinatal network between September and December 2018. The inclusion criterion was a birth term of≥41+0 weeks of gestation. Primary outcome was conformity to the national guidelines based on 10 items (conformity score≥80%). The secondary outcome was a composite criteria of neonatal morbidity (ventilation, resuscitation and/or Apgar score<7 at 5minutes) and maternal morbidity (obstetrical anal sphincter injury and/or postpartum hemorrhage). RESULTS: A total of 596 patients were included and the conformity was obtained in 65.3% of cases. Inconsistent criteria were amniotic fluid evaluation by the deepest vertical pocket (46.8%, n=279), and information of patients on prolonged pregnancy management (14.8%, n=88). Adverse perinatal outcome occurred for 40 newborns (6.0%) with shoulder dystocia (OR=5.2; CI 95%: 1.4-19.7) as a principal risk factor. Maternal morbidity outcome occurred in 70 cases (10.6%) primarily with increase in labour duration (OR=1.1 by hour of labour; CI 95%: 1.02-1.24) and prior caesarian section (OR=4.4; CI 95%: 1.8-11.0). CONCLUSIONS: Management of prolonged and post-term pregnancies matching with the French national guidelines. Points of improvement are amniotic fluid evaluation at term by a single deepest vertical pocket, and the information about induction of labour at term.

How to assess hemodynamic status in very preterm newborns in the first week of life?

BACKGROUND: Assessing hemodynamic status in preterm newborns is an essential task, as many studies have shown increased morbidity when hemodynamic parameters are abnormal. Although oscillometric monitoring of arterial blood pressure (BP) is widely used due to its simplicity and lack of side effects, these values are not always correlated with microcirculation and oxygen delivery. OBJECTIVES: This review focuses on different tools for the assessment of hemodynamic status in preterm newborns. These include the measurement of clinical (BP, capillary refill time and urinary output (UO)) or biological parameters (lactate analysis), functional echocardiography, and near-infrared spectroscopy (NIRS). We describe the concepts and techniques involved in these tools in detail, and examine the interest and limitations of each type of assessment. CONCLUSIONS: This review highlights the complementarities between the different parameters used to assess hemodynamic status in preterm newborns during the first week of life. The analysis of arterial BP measured by oscillometric monitoring must take into account other clinical data, in particular capillary refill time and UO, and biological data such as lactate levels. Echocardiography improves noninvasive hemodynamic management in newborns but requires specific training. In contrast, NIRS may be useful in monitoring the clinical course of infants at risk of, or presenting with, hypotension. It holds the potential for early and noninvasive identification of silent hypoperfusion in critically ill preterm infants. However, more data are needed to confirm the usefulness of this promising tool in significantly changing the outcome of these infants.

Association of severe placental inflammation with death prior to discharge and cerebral palsy in preterm infants.

OBJECTIVE: The objective of our study was to identify placental patterns associated with death before discharge or cerebral palsy in a large cohort of preterm infants with a high follow-up rate at 2 years of corrected age. DESIGN: Population-based monocentric study. SETTINGS: Monocentric study in the maternity unit of the University Hospital of Angers, France between 24+0 and 33+6  weeks of gestation, between January 2008 and December 2011. POPULATION: All singleton infants born alive with a placental examination were eligible. METHODS: Clinical data (obstetric and neonatal) were collected prospectively through the LIFT cohort. Placental data were collected retrospectively from medical records. The main outcome measure was death before discharge or cerebral palsy. RESULTS: We did not find any significant association between severe inflammatory lesions on the placenta and death [odds ratio (OR) 1.49; 95% CI 0.55-4.01; P = 0.43] or cerebral palsy (OR 1.41; 95% CI 0.43-4.62; P = 0.57). This lack of significant association persisted even after adjustment (aOR 0.9; 95% CI 0.20-2.30; P = 0.54; aOR 0.98; 95% CI 0.27-3.58; P = 0.97). CONCLUSION: Our results do not provide evidence for a significant association between severe inflammatory placental lesions and either death before discharge or cerebral palsy at 2 years of corrected age in preterm infants born at <34 weeks of gestational age. Further studies remain necessary to confirm this result. TWEETABLE ABSTRACT: We found no significant association between inflammatory placental lesions and death or cerebral palsy.

[Early complications and management of newborns during the first month of life]. / Le nouveau-né en maternité et durant le premier mois de vie.

OBJECTIVE: To describe early complications and management of newborns during the first month of life. METHODS: This systematic evidence review is based on Pubmed search, Cochrane library and experts recommendations. RESULTS: There is no optimal time for maternity discharge for low risk newborn in regard of the literature. It depends more on the organisation of the post-discharge follow-up (professional consensus). Extreme hyperbilirubinemia expose to neonatal mortality and severe neurodevelopmental impairment for survivors (level of evidence: 1). Neonatal hyperbilirubinemia occurs in almost all newborns and may be benign if its progression is monitored (transcutaneous bilirubinometer, capillar or venous bilirubin level) at least 24hours after any early discharge (professional consensus). Asymptomatic newborns with high risks of neonatal sepsis have to be closely monitored during the first 48hours of life (professional consensus). Clinical assessment (heart murmure and femoral pulse) at least 24hours after any early discharge and at any clinical examination almost up to 1 month after birth is recommended to detect possible congenital heart disease (professional consensus). Serial clinical examination of the hips by a trained clinician in the periodic health examination of all infants until they are walking independently is recommended (professional consensus). Neonatal screening blood tests are recommended between 60 and 84hours of life in every newborns, can be advanced between 48 and 60hours if necessary but never before 48hours of life (professional consensus). Neonatal screening of deafness is recommended in every newborns and has to be assessed before maternity discharge (professional consensus). All these data have to be reported in the newborn personal medical file (professional consensus). CONCLUSION: Early discharge has to be prepared during the prenatal period in order to ensure care continuity at home and to avoid any severe neonatal outcome.

[Post-partum: Guidelines for clinical practice--Short text]. / Post-partum: recommandations pour la pratique Clinique--Texte court.

OBJECTIVE: To determine the post-partum management of women and their newborn whatever the mode of delivery. MATERIAL AND METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Because breastfeeding is associated with a decrease in neonatal morbidity (lower frequency of cardiovascular diseases, infectious, atopic or infantile obesity) (EL2) and an improvement in the cognitive development of children (EL2), exclusive and extended breastfeeding is recommended (grade B) between 4 to 6 months (Professional consensus). In order to increase the rate of breastfeeding initiation and its duration, it is recommended that health professionals work closely with mothers in their project (grade A) and to promote breastfeeding on demand (grade B). There is no scientific evidence to recommend non-pharmacological measures of inhibition of lactation (Professional consensus). Pharmacological treatments for inhibition of lactation should not be given routinely to women who do not wish to breastfeed (Professional consensus). Because of potentially serious adverse effects, bromocriptin is contraindicated in inhibiting lactation (Professional consensus). For women aware of the risks of pharmacological treatment of inhibition of lactation, lisuride and cabergolin are the preferred drugs (Professional consensus). Whatever the mode of delivery, numeration blood count is not systematically recommended in a general population (Professional consensus). Anemia must be sought only in women with bleeding or symptoms of anemia (Professional consensus). The only treatment of post-dural puncture headache is the blood patch (EL2), it must not be carried out before 48 h (Professional consensus). Women vaccination status and their family is to be assessed in the early post-partum (Professional consensus). Immediate postoperative monitoring after caesarean delivery should be performed in the recovery room, but in exceptional circumstances, it may be performed in the delivery unit provided safety rules are maintained and regulatory authorities are informed (Professional consensus). An analgesic multimodal protocol developed by the medical team should be available and oral way should be favored (Professional consensus) (grade B). For every cesarean delivery, thromboprophylaxis with elastic stockings applied on the morning of the surgery and kept for at least 7 postoperative days is recommended (Professional consensus) with or without the addition of LMWH according to the presence or not of additional risk factors, and depending on the risk factor (major, minor). Early postoperative rehabilitation is encouraged (Professional consensus). Postpartum visit should be planned 6 to 8 weeks after delivery and can be performed by an obstetrician, a gynecologist, a general practitioner or a midwife, after normal pregnancy and delivery (Professional consensus). Starting effective contraception later 21 days after delivery in women who do not want closely spaced pregnancy is recommended (grade B), and to prescribe it at the maternity (Professional consensus). According to the postpartum risk of venous thromboembolism, the combined hormonal contraceptive use before six postpartum weeks is not recommended (grade B). Rehabilitation in asymptomatic women in order to prevent urinary or anal incontinence in medium or long-term is not recommended (Expert consensus). Pelvic-floor rehabilitation using pelvic-floor muscle contraction exercises is recommended to treat persistent urinary incontinence at 3 months postpartum (grade A), regardless of the type of incontinence. Postpartum pelvic-floor rehabilitation is recommended to treat anal incontinence (grade C). Postpartum pelvic-floor rehabilitation is not recommended to treat or prevent prolapse (grade C) or dyspareunia (grade C). The optimal time for maternity discharge for low risk newborn depends more on the organisation of the post-discharge follow up (Professional consensus). The months following the birth are a transitional period, and psychological alterations concern all parents (EL2). It is more difficult in case of psychosocial risk factors (EL2). In situations of proven psychological difficulties, the impact on the psycho-emotional development of children can be important (EL3). Among these difficulties, postpartum depression is the most common situation. However, the risk is generally higher in the perinatal period for all mental disorders (EL3). CONCLUSION: Postpartum is, for clinicians, a unique and privileged opportunity to address the physical, psychological, social and somatic health of their patients.

Fetal growth restriction and intra-uterine growth restriction: guidelines for clinical practice from the French College of Gynaecologists and Obstetricians.

Small for gestational age (SGA) is defined by weight (in utero estimated fetal weight or birth weight) below the 10th percentile (professional consensus). Severe SGA is SGA below the third percentile (professional consensus). Fetal growth restriction (FGR) or intra-uterine growth restriction (IUGR) usually correspond with SGA associated with evidence indicating abnormal growth (with or without abnormal uterine and/or umbilical Doppler): arrest of growth or a shift in its rate measured longitudinally (at least two measurements, 3 weeks apart) (professional consensus). More rarely, they may correspond with inadequate growth, with weight near the 10th percentile without being SGA (LE2). Birthweight curves are not appropriate for the identification of SGA at early gestational ages because of the disorders associated with preterm delivery. In utero curves represent physiological growth more reliably (LE2). In diagnostic (or reference) ultrasound, the use of growth curves adjusted for maternal height and weight, parity and fetal sex is recommended (professional consensus). In screening, the use of adjusted curves must be assessed in pilot regions to determine the schedule for their subsequent introduction at national level. This choice is based on evidence of feasibility and the absence of any proven benefits for individualized curves for perinatal health in the general population (professional consensus). Children born with FGR or SGA have a higher risk of minor cognitive deficits, school problems and metabolic syndrome in adulthood. The role of preterm delivery in these complications is linked. The measurement of fundal height remains relevant to screening after 22 weeks of gestation (Grade C). The biometric ultrasound indicators recommended are: head circumference (HC), abdominal circumference (AC) and femur length (FL) (professional consensus). They allow calculation of estimated fetal weight (EFW), which, with AC, is the most relevant indicator for screening. Hadlock's EFW formula with three indicators (HC, AC and FL) should ideally be used (Grade B). The ultrasound report must specify the percentile of the EFW (Grade C). Verification of the date of conception is essential. It is based on the crown-rump length between 11 and 14 weeks of gestation (Grade A). The HC, AC and FL measurements must be related to the appropriate reference curves (professional consensus); those modelled from College Francais d'Echographie Fetale data are recommended because they are multicentere French curves (professional consensus). Whether or not a work-up should be performed and its content depend on the context (gestational age, severity of biometric abnormalities, other ultrasound data, parents' wishes, etc.) (professional consensus). Such a work-up only makes sense if it might modify pregnancy management and, in particular, if it has the potential to reduce perinatal and long-term morbidity and mortality (professional consensus). The use of umbilical artery Doppler velocimetry is associated with better newborn health status in populations at risk, especially in those with FGR (Grade A). This Doppler examination must be the first-line tool for surveillance of fetuses with SGA and FGR (professional consensus). A course of corticosteroids is recommended for women with an FGR fetus, and for whom delivery before 34 weeks of gestation is envisaged (Grade C). Magnesium sulphate should be prescribed for preterm deliveries before 32-33 weeks of gestation (Grade A). The same management should apply for preterm FGR deliveries (Grade C). In cases of FGR, fetal growth must be monitored at intervals of no less than 2 weeks, and ideally 3 weeks (professional consensus). Referral to a Level IIb or III maternity ward must be proposed in cases of EFW <1500g, potential birth before 32-34 weeks of gestation (absent or reversed umbilical end-diastolic flow, abnormal venous Doppler) or a fetal disease associated with any of these (professional consensus). Systematic caesarean deliveries for FGR are not recommended (Grade C). In cases of vaginal delivery, fetal heart rate must be monitored continuously during labour, and any delay before intervention must be faster than in low-risk situations (professional consensus). Regional anaesthesia is preferred in trials of vaginal delivery, as in planned caesareans. Morbidity and mortality are higher in SGA newborns than in normal-weight newborns of the same gestational age (LE3). The risk of neonatal mortality is two to four times higher in SGA newborns than in non-SGA preterm and full-term infants (LE2). Initial management of an SGA newborn includes combatting hypothermia by maintaining the heat chain (survival blanket), ventilation with a pressure-controlled insufflator, if necessary, and close monitoring of capillary blood glucose (professional consensus). Testing for antiphospholipids (anticardiolipin, circulating anticoagulant, anti-beta2-GP1) is recommended in women with previous severe FGR (below third percentile) that led to birth before 34 weeks of gestation (professional consensus). It is recommended that aspirin should be prescribed to women with a history of pre-eclampsia before 34 weeks of gestation, and/or FGR below the fifth percentile with a probable vascular origin (professional consensus). Aspirin must be taken in the evening or at least 8h after awakening (Grade B), before 16 weeks of gestation, at a dose of 100-160mg/day (Grade A).

[Evaluation of the impact and efficiency of high-fidelity simulation for neonatal resuscitation in midwifery education]. / Évaluation de la simulation haute-fidélité dans la formation initiale à la réanimation en salle de naissance chez les étudiants sages-femmes.

BACKGROUND: Prompt initiation of appropriate neonatal resuscitation skills is critical for the neonate experiencing difficulty transitioning to extra-uterine life. Expertise in neonatal resuscitation is essential for personnel involved in the care of newborns, above all for midwives who are sometimes alone to initiate the first resuscitation. The use of simulation training is considered to be an indispensable tool to address these challenges, not only in continuing education but also in midwifery education. OBJECTIVE: The aim of this study was to evaluate the impact and efficiency of high-fidelity simulation for neonatal resuscitation in midwifery education. METHODS: This was a prospective monocentric study conducted in the Angers university hospital between October and December 2012 and included two groups of midwifery students (n=40) who received high-fidelity simulation as part of their basic midwifery education. Participants' perceptions of the knowledge, skills, and confidence gained following training in high-fidelity simulation for neonatal resuscitation were determined using a pre-/post-test questionnaire design completed during the training and also several months after the course, as well as after the students had begun working. A satisfaction survey to evaluate this training was also completed at the same time. RESULTS: With a good participation rate (67.5%), the survey showed a high degree of satisfaction among the participants. This training was described as facilitating their hire in one third of cases. A significant increase in self-assessment of skills scores was observed between the pre-test and post-test (P<0.001), the pre-test and the distance test (P<0.001), and the post-test and distance test (P=0.007). Although a decrease in the median score was observed on the knowledge questionnaire given as a post-test, this median remained significantly higher than that obtained on the pre-test (P=0.03). CONCLUSION: The significant improvement in knowledge during the session and its preservation after a few months confirmed the efficacy of this teaching method. The simulation training increased the participants' perceptions of their knowledge, skills, and confidence in conducting neonatal resuscitation. These preliminary results are very encouraging and argue in favor of generalizing this teaching method. However, this training could be more profitable if it was proposed earlier in the midwifery curriculum and organized with a multidisciplinary team (pediatric and anesthesia residents).

Early growth and neurodevelopmental outcome in very preterm infants: impact of gender.

BACKGROUND AND OBJECTIVE: Nutrition in the neonatal unit may impact the neurological outcome of very preterm infants, and male preterms are more likely to suffer neonatal morbidity and adverse neurological outcomes. We hypothesised that growth during hospitalisation would impact neurological outcome differently, depending on infant gender. METHODS: Surviving infants born between 1 January 2003 and 31 December 2009 with a gestational age <33 weeks, and enrolled in Loire Infant Follow-up Team, a regional cohort in western France, qualified for the study. Growth during neonatal hospitalisation was assessed by the change in weight z-score between birth and discharge, and infants where ranked into 5 classes, depending on their change in z-score (<-2, -2 to -1.01, -1 to -0.51, -0.50 to 0.01 and ≥0), the last class being the reference. The main outcome criterion was neurodevelopmental outcome at 2 years of corrected age. For each class of changes in weight z-score, crude or adjusted OR for non-optimal outcome was calculated for each gender, and compared between genders. RESULTS: 1221 boys and 1056 girls were included. Gender and early growth interact, (p=0.02). Moreover when change in weight z-score varied from <-2 to (-0.50 to -0.01), adjusted OR for non-optimal outcome varied from 3.2 (1.5-6.8) to 2.2 (1.2-4.1) in boys versus 1.8 (0.7-4.2) to 0.95 (0.4-1.9) in girls. For each class, the OR was significantly higher in boys. CONCLUSIONS: In very preterm infants, male neurodevelopment appears to be much more sensitive than female to poor postnatal growth.

[Short-term outcome and small for gestational age newborn management]. / Devenir précoce et prise en charge néonatale du nouveau-né petit pour l'âge gestationnel.

OBJECTIVE: To describe early complications and management of the small for gestational age (SGA) neonate. METHODS: This systematic evidence review is based on Pubmed search, Cochrane library and experts recommendations. Words included in the search mainly were: small for gestational age, intrauterine growth restriction, fetal growth restriction, very low birth weight infants, neonatal management, neonatal outcome, neonatal morbidity, neonatal mortality RESULTS: Neonatal mortality relative risk among SGA infants is 2-4 times higher than adapted for gestational age (AGA) newborn infants, at any gestational age. SGA infants had an increased risk for perinatal asphyxia, hypothermia and hypoglycaemia during their first days of life. In the SGA preterm population, bronchopulmonary dysplasia, pulmonary hypertension and necrotising enterocolitis are significantly more frequent as compared with AGA population. Periventricular leukomalacia is not significantly different between SGA and AGA infants whereas intraventricular hemorrhage and retinopathy risks are discussed. Adaptive problems require paediatric contact before birth. Early management of the small for gestational age includes intervention to prevent hypothermia, the use of pressure controlled ventilator if needed, and close blood glucose monitoring. CONCLUSIONS: SGA infants had excess neonatal mortality and morbidity in comparison with adapted ones for gestational age (AGA) infants, especially for preterm infants.

[Long-term outcome in context of intra uterine growth restriction and/or small for gestational age newborns]. / Conséquences à long terme des enfants nés dans un contexte de retard de croissance intra-utérin et/ou petits pour l'âge gestationnel.

OBJECTIVE: To evaluate long-term outcome after history of intra-uterine growth restriction (IUGR) and/or birth small for gestational age (SGA). METHODS: This systematic evidence review is based on Pubmed search, Cochrane library and experts recommendations. RESULTS: Neurodevelopmental evaluation at 2 years is lower in those infants, born premature or not. SGA is associated with a high risk of minor cognitive deficiencies, hyperactivity or attention deficit disorders at 5 years or scholar difficulties at 8 years. Those infants are at high risk of metabolic syndrome in adulthood. Most of them will catch up at 6 months for weight and 12 months for height. Even if IUGR is associated with high risk of bronchodysplasia, up to this day, the review of literature did not permit to evaluate respiratory outcome. Adults born SGA have good quality of live and normal professional insertion. One cohort study and more and more animal studies suggest potential trans generational effects. CONCLUSION: Infants born SGA and/or with history of IUGR are at high risk of minor cognitive deficiencies and scholar difficulties. They are also at high risk of metabolic syndrome in adulthood. However, prematurity seems to have a higher effect than IUGR and/or SGA on long-term outcomes.
