Outcomes of pregnancies with preterm premature rupture of membranes occurring before 24 weeks of gestation: An 11-year observational study.

OBJECTIVE: This study describes the fetal and neonatal outcomes and their predictive factors in pregnancies with preterm premature rupture of membranes (PPROM) before 24 weeks of gestation. METHODS: A retrospective study was conducted using the patient database of a tertiary university hospital in Lyon, France. All of the medical data of women diagnosed with PPROM before 24 weeks of gestation from 2008 to 2018 were extracted. R software was used for descriptive and analytical statistics. RESULTS: The study included 78 women. Mean gestational age (GA) at PPROM was 19.6 weeks (13.1 to 23.9 weeks). Fifteen (19.2%) pregnancies were terminated, 37 (47.4%) resulted in intrauterine fetal death (IUFD), and 26 (33.3%) children were born alive at an average of 26.9 weeks of gestation. Fourteen children survived and 12 died after birth; 50% of survivors had pulmonary hypoplasia. Within 7 days after PPROM, 46% of IUFD occurred and 36% of pregnancies ended. PPROM before 20 weeks of gestation and chorioamnionitis are statistically associated with IUFD, whereas a latency period of more than 2 weeks is statistically related to live birth. CONCLUSION: PPROM before 24 weeks of gestation is associated with a high rate of IUFD, preterm birth, and postpartum mortality.

Impact of a nurse education programme on oral feeding in a neonatal unit.

BACKGROUND: Premature neonates often experience feeding difficulties during their hospital stay, and evidence-based interventions have been shown to improve feeding outcomes. AIM: This study investigated whether an infant-cue based nurse educational feeding bundle accelerates the achievement of independent oral feeding in neonates in a neonatal intensive care unit. STUDY DESIGN: A quality improvement study with a pre, during and post intervention test design. All premature neonates admitted to the unit were eligible. The feeding programme included a four-month nurse training module and nurse coaching. RESULTS: A hundred and twenty-five nurses or nurse assistants attended the programme and 706 neonates were included. The median time to independent oral feeding (IOF) was 40, 36 and 37 days, respectively, for pre, during and post intervention. The reduction in time to IOF observed during the post-intervention period compared with the baseline period was significant (HR = 1.32, CI 95%: 1.01-1.74). No difference was noted in the length of hospital stay between the three study periods. CONCLUSIONS: An infant-cue based nurse educational feeding bundle can promote earlier achievement of IOF in preterm neonates. RELEVANCE TO CLINICAL PRACTICE: This quality improvement study demonstrates the impact that a nurse-driven intervention in neonatal care can have on improving practice. Feeding interventions involve the early introduction of oral feeding, non-nutritive sucking (NNS), and oral motor stimulation, and should be individualized for each neonate. These individualized feeding interventions applied by all nurses and assistant nurses, can facilitate the achievement of earlier independent oral feeding in preterm infants and should be included in neonatal critical care nurse education programs.

Protocol of controlled odorant stimulation for reducing apnoeic episodes in premature newborns: a randomised open-label Latin-square study with independent evaluation of the main endpoint (PREMODEUR).

INTRODUCTION: Apnoea affects 85% of premature infants under 34 weeks of age and would be an important risk factor for subsequent neuropsychological disorders. Currently, premature children with life-threatening apnoeas receive stimulants such as methylxanthines (mainly, caffeine) or doxapram (an analeptic unlicensed in children under 15). However, these products have undesirable effects (hyperarousal, irritability, sleep disorders, tachycardia) and are not always effective because apnoea does persist in some premature newborns. Previous studies have indicated that odorant stimulation, a non-invasive intervention, may stimulate the respiratory rhythm. The objective of the present protocol is to reduce the occurrence of apnoeic episodes in premature newborns by controlled odorant stimulation added to current pharmacological treatments. METHODS AND ANALYSIS: The project is a randomised open-label Latin-square trial with independent evaluation of the main endpoint. It will include 60 preterm neonates from two university hospital neonatal intensive care units over 2 years (2021-2023). Each newborn will receive no (S0), sham (S1) or real olfactory stimulation (S2) in random order. During S2, three distinct odorants (mint, grapefruit and vanilla) will be delivered successively, in puffs, over 24 hours. Mint and grapefruit odours stimulate the main and the trigeminal olfactory pathways, whereas vanilla odour stimulates only the main olfactory pathway. A statistical analysis will compare the incidence of apnoeic episodes during S1 versus S2 using a mixed effects Poisson model. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Comité de Protection des Personnes Île-de-France XI (# 2017-AO13-50-53). The results will be disseminated through various scientific meetings, specialised peer-reviewed journals and, whenever possible, posted on appropriate public websites. TRIAL REGISTRATION NUMBER: NCT02851979; Pre-results.

Intrauterine Growth Restriction and Hypertrophic Cardiomyopathy as Prenatal Ultrasound Findings in a Case of Leprechaunism.

Donohue syndrome (leprechaunism; OMIM *246200) is a rare and often lethal autosomal recessive disease caused by mutations in the INSR gene. We report the case of a 29-year-old pregnant woman, primigravida, who was referred at 33 weeks of gestation for severe intrauterine growth restriction (IUGR). Ultrasound examination found severe IUGR associated with an obstructive hypertrophic cardiomyopathy (HCM), confirmed postnatally. The newborn's blood glucose level fluctuated from fasting hypoglycemia to postprandial hyperglycemia. The infant was found to be homozygous for a novel missense pathogenic variant, c.632C>T (p.T211l), in exon 2 of the INSR gene, predicted to result in an abnormal insulin receptor. To our knowledge, this is the first report of leprechaunism being revealed by IUGR and HCM during the prenatal period. Clinicians should keep in mind that the association of these prenatal signs could indicate leprechaunism and specific early neonatal management could be proposed, in particular with recombinant human insulin-like growth factor-I.

Effectiveness of a nurse educational oral feeding programme on feeding outcomes in neonates: protocol for an interrupted time series design.

INTRODUCTION: Oral feeding is a complex physiological process. Several scales have been developed to assess the ability of the neonate to begin suck feedings and assist caregivers in determining feeding advancement. However, feeding premature neonates remains an ongoing challenge and depends above all on caregivers' feeding expertise. We will evaluate the effect of a nurse training programme on the achievement of full oral feeding with premature neonates. METHODS AND ANALYSIS: The study design will be an interrupted time series design with 3 phases: (1) A 6-month baseline period; (2) a 22-month intervention period and (3) a 6-month postintervention period. The intervention will consist of an educational programme, for nurses and assistant nurses, on feeding patterns in neonates. The training modules will be composed of a 2-day conference, 2 interactive multidisciplinary workshops, and routine practice nurse coaching. A total of 120 nurses and 12 assistant nurses, who work at the neonatal unit during the study period, will participate in the study. All premature neonates of <34 weeks postmenstrual age (PMA) will be included. The primary outcome will be the age of tube withdrawal PMA and chronological age are taken into account. The secondary outcomes will be the transition time, length of hospital stay, competent suckle feeding without cardiorespiratory compromise, rate of neonates presenting with feeding issues or feeding rejection signs, and current neonatal pathologies or deaths during hospital stay. A segmented regression analysis will be performed to assess the impact of the programme. ETHICS AND DISSEMINATION: Approval for the study was obtained from the Hospital Ethics Committee, and the Institutional Review Board, as well as the French Data Protection Agency. The findings from the study will be disseminated through peer-reviewed journals, national and international conference presentations and public events. TRIAL REGISTRATION NUMBER: NCT02404272 (https://clinicaltrials.gov).

In situ simulation training for neonatal resuscitation: an RCT.

OBJECTIVES: High-fidelity simulation is an effective tool in teaching neonatal resuscitation skills to professionals. We aimed to determine whether in situ simulation training (for ∼80% of the delivery room staff) improved neonatal resuscitation performed by the staff at maternities. METHODS: A baseline evaluation of 12 maternities was performed: a random sample of 10 professionals in each unit was presented with 2 standardized scenarios played on a neonatal high-fidelity simulator. The medical procedures were video recorded for later assessments. The 12 maternities were then randomly assigned to receive the intervention (a 4-hour simulation training session delivered in situ for multidisciplinary groups of 6 professionals) or not receive it. All maternities were evaluated again at 3 months after the intervention. The videos were assessed by 2 neonatologists blinded to the pre-/postintervention as well as to the intervention/control groups. The performance was assessed using a technical score and a team score. RESULTS: After intervention, the median technical score was significantly higher for scenarios 1 and 2 for the intervention group compared with the control group (P = .01 and 0.004, respectively), the median team score was significantly higher (P < .001) for both scenarios. In the intervention group, the frequency of achieving a heart rate >90 per minute at 3 minutes improved significantly (P = .003), and the number of hazardous events decreased significantly (P < .001). CONCLUSIONS: In situ simulation training with multidisciplinary teams can effectively improve technical skills and teamwork in neonatal resuscitation.
