BACKGROUND: The prognosis for late-onset sepsis depends largely on a timely diagnosis. We assess central-peripheral temperature difference monitoring as a marker for late-onset neonatal sepsis diagnosis. METHODS: We performed a prospective, observational study focusing on a cohort of 129 very low birth weight infants. Thermal gradient alteration was defined as a difference of > 2°C maintained during 4 hours. We then determined its association with the late-onset sepsis variable through logistic regression...

Objective Premature birth is associated with numerous complex abnormalities of white and grey matter and a high incidence of long-term neurocognitive impairment. An integrated understanding of these abnormalities and their association with clinical events is lacking. The aim of this study was to identify specific patterns of abnormal cerebral development and their antenatal and postnatal antecedents. Methods In a prospective cohort of 449 infants (226 male), we performed a multi-variate and data-driven analysis combining multiple imaging modalities...

Despite decades of investigations and accumulated scientific knowledge, preterm birth (PTB) remains a significant burden worldwide. Several mechanisms have been proposed to explain this condition, and a number of risk factors from infectious to behavioral and genetic/epigenetic factors influence this outcome. The heritability of PTB is estimated to be 17% to 36%, which demonstrates that genetic predisposition plays a key role in PTB. Structural DNA modifications without changes in the DNA sequence and post-transcriptional regulation also have an impact on gene expression and thus influence pregnancy outcomes...

BACKGROUND: Noninvasive ventilation (NIV) significantly changed the management of respiratory distress syndrome (RDS) in preterm infants. Further perspectives for neonatologists regard the assessment of different NIV strategies in terms of availability, effectiveness and failure. OBJECTIVE: The aim of the present study is to evaluate the effectiveness of three different NIV strategies: nasal continuous pressure (N-CPAP), nasal synchronized intermittent positive pressure ventilation (N-SIPPV) and nasal bilevel CPAP (BiPAP), as first intention treatment for RDS in very low birth-weight infants (VLBW)...

AIM: We designed a safety and dose-finding trial of tadalafil administered for fetal growth restriction (FGR). METHODS: Three cases were initially commenced on 10 mg/day and monitored for major adverse events. Should a major adverse event be observed in one or more of the three cases, an examination into its relation with tadalafil would be conducted by a safety evaluation committee. If one or more of these new cases exhibited the same adverse event, the trial would be stopped completely...

Aim To investigate whether increased brain natriuretic propeptide (NT-proBNP) levels at 48 to 72 h of life are associated with the development of bronchopulmonary dysplasia (BPD) or death in premature neonates. Methods A retrospective study was performed in neonates born before 32 weeks' gestation or with birth weight below 1500 grams, in whom NT-proBNP determination and echocardiography were performed at 48 to 72 h of life. Associations between NT-proBNP levels and the combined outcome BPD or death were analyzed using multivariate logistic regression analysis...

PURPOSE: Prior studies suggest that pregnancy outcomes after autologous oocyte cryopreservation are similar to fresh in vitro fertilization (IVF) cycles. It is unknown whether there are differences in pregnancy and perinatal outcomes between cryopreserved oocytes and cryopreserved embryos. METHODS: This is a retrospective cohort study comparing pregnancy and perinatal outcomes between oocyte and embryo cryopreservation at a university-based fertility center. We included 42 patients and 68 embryo transfers in patients who underwent embryo transfer after elective oocyte preservation (frozen oocyte-derived embryo transfer (FOET)) from 2005 to 2015...

The cervix represents a formidable structural barrier for successful induction of labor. Approximately 10% of pregnancies undergo induction of cervical ripening and labor with prostaglandin (PG) E2 or PGE analogs, often requiring many hours of hospitalization and monitoring. On the other hand, preterm cervical ripening in the second trimester predicts preterm birth. The regulatory mechanisms of this paradoxical function of the cervix are unknown. Here, we show that PGE2 uses cell-specific EP2 receptor-mediated increases in Ca(2+) to dephosphorylate and translocate histone deacetylase 4 (HDAC4) to the nucleus for repression of 15-hydroxy prostaglandin dehydrogenase (15-PGDH)...

Supraventricular tachycardia (SVT) is the most common neonatal arrhythmia. Necrotising enterocolitis (NEC) is a disease with multifactorial aetiology, most common in preterm infants. There are three previous case reports in the literature of NEC following neonatal SVT. We present two cases of late preterm infants with NEC, characterised by pneumatosis on abdominal X-ray and ultrasound, following recurrent SVT without haemodynamic instability. The infants were successfully treated with antibiotic therapy and bowel rest...

BACKGROUND: Extremely preterm infants (≤ 28 weeks gestation) commonly require endotracheal intubation and mechanical ventilation (MV) to maintain adequate oxygenation and gas exchange. Given that MV is independently associated with important adverse outcomes, efforts should be made to limit its duration. However, current methods for determining extubation readiness are inaccurate and a significant number of infants fail extubation and require reintubation, an intervention that may be associated with increased morbidities...

OBJECTIVE: To evaluate the Fetal Medicine Foundation (FMF) algorithm prospectively at 11-13 weeks' gestation in the prediction of preeclampsia (PE). METHODS: Single-center prospective screening study for PE of singleton pregnancies at 11-13 weeks. The FMF algorithm takes into account maternal characteristics and biomarkers. Detection rate (DR) for a 10% false-positive rate (FPR) for delivery with preterm and term PE was estimated. RESULTS: Between January 2011 and December 2013, of 3,239 patients available for final analysis, 36 (1...

AIM: In this study, we evaluate the associations between fetal urinary production rate (FUPR), measured by ultrasound, and adverse neonatal outcome in women with preterm premature rupture of membranes (PPROM). METHODS: We conducted a prospective pilot cohort of singleton pregnancies complicated by PPROM occurring at gestational week 24 or later managed until spontaneous labor (after 48 h of admission), chorioamnionitis, or induction by protocol at 35 + 0 weeks. FUPR was evaluated by 2D sonography at admission (corrected for gestational age)...

BACKGROUND: A high proportion of extremely preterm (EPT) infants are born by cesarean section (CS). However, whether the mode of delivery is related to long-term neurodevelopment in these infants is unclear. OBJECTIVES: This study aimed to determine whether the mode of delivery is associated with mortality and long-term outcomes in EPT infants. METHODS: We analyzed data of the Neonatal Research Network in Japan (NRNJ), a population-based, nationwide registry...

INTRODUCTION: Several studies report a decrease of fetal heart rate (FHR) short-term variation (STV) after corticosteroids for improvement of fetal maturity and advice not to deliver a fetus for low STV within 2-3days after corticosteroids. However, literature is not unanimous in this respect. This study intends to asses STV longitudinally after corticosteroid administration. MATERIAL AND METHODS: A retrospective cohort study in a tertiary perinatal centre from 2009 to 2015 included all women who had been treated with corticosteroids at gestational age of 26-34 weeks, had a computerized cardiotocography (cCTG) before and after medication and did not deliver within 48h...

Oral sucrose is administered routinely to reduce pain of minor procedures in premature infants and is recommended as standard care in international guidelines. No human or animal studies on effects of early repeated sucrose exposure on long-term brain development have been done in the context of pain. We evaluated the effects of repeated neonatal sucrose treatment before an intervention on long-term brain structure in mouse pups. Neonatal C57Bl/6J mice (n = 109) were randomly assigned to one of 2 treatments (vehicle vs sucrose) and one of 3 interventions (handling, touch, or needle-prick)...

REVIEW
Zsofia Nemoda, Moshe Szyf
Major depressive disorder of the mother affects 6 to 17% of pregnancies worldwide and can lead to negative outcomes, such as preterm delivery and later mental health problems of the child. It has been proposed that developmental programming has long-lasting effects in the offspring that might be mediated by epigenetic mechanisms, such as DNA methylation. Altered stress regulation or impaired immunological function of the mother can potentially affect DNA methylation processes of the fetus, changing gene expression levels in utero...
