BACKGROUND: There are conflicting results in the literature on the impact of chorioamnionitis on neonatal respiratory morbidities. However, most studies are based on small clinical samples and fail to account for the competing risk of perinatal death. This study aimed to determine whether chorioamnionitis affects the incidence of respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD) after accounting for the increased risk of death. METHODS: Retrospective cohort study using linked birth and infant death registration and hospitalization records from Washington State between 2002 and 2011 (n = 763,671 singleton infants and n = 56,537 singleton preterm infants)...

The C242T polymorphism of CYBA (cytochrome B-245 alpha chain), the gene encoding the p22phox subunit of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, has been linked to several conditions in which oxidative stress plays a pathogenic role. We investigated in a cohort of 451 preterm infants [gestational age (GA) ≤30 weeks] the association of the polymorphism with the risk of developing neonatal respiratory distress syndrome (RDS), retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), necrotizing enterocolitis, patent ductus arteriosus, or intraventricular hemorrhage...

Pulmonary surfactant (PS), which is synthesized by type II alveolar epithelial cells (AECIIs), maintains alveolar integrity by reducing surface tension. Many premature neonates who lack adequate PS are predisposed to developing respiratory distress syndrome (RDS), one of the leading causes of neonatal morbidity and mortality. PS synthesis is influenced and regulated by various factors, including microRNAs. Previous in vitro studies have shown that PS synthesis is regulated by miR-26a in fetal rat AECIIs. This study aimed to investigate the role of miR-26a in PS synthesis in vivo...

BACKGROUND: Respiratory morbidity including respiratory distress syndrome (RDS) is a serious complication of preterm birth and the primary cause of early neonatal mortality and disability. While researching the effects of the steroid dexamethasone on premature parturition in fetal sheep in 1969, Liggins found that there was some inflation of the lungs of lambs born at gestations at which the lungs would be expected to be airless. Liggins and Howie published the first randomised controlled trial in humans in 1972 and many others followed...

BACKGROUND: Counseling for patients with impending premature delivery traditionally has been based primarily on the projected gestational age at delivery. There are limited data regarding how the indications for the preterm birth affect the neonatal outcome and whether this issue should be taken into account in decisions regarding management and patient counseling. OBJECTIVE: We performed a prospective study of pregnancies resulting in premature delivery at less than 32 weeks to determine the influence of both the indications for admission and their associated indications for delivery on neonatal mortality and complications of prematurity...

Diabetes is alarmingly high among Bangladeshi people. But there have been very few studies assessing the effect of diabetes on perinatal outcomes, particularly comparing diabetes prior to pregnancy and gestational diabetes (GDM). This cross sectional observational study was conducted in the Department of Obstetrics & Gynaecology, BIRDEM Hospital, Dhaka, Bangladesh from September 2010 to February 2011. Pregnant women admitted in BIRDEM Hospital for delivery after 28 weeks of gestation were selected to assess perinatal complications of GDM and diabetes prior to pregnancy and to compare them after taking permission from institutional review board...

BACKGROUND: Current management of preterm prelabour rupture of the membranes (PPROM) involves either initiating birth soon after PPROM or, alternatively, adopting a 'wait and see' approach (expectant management). It is unclear which strategy is most beneficial for mothers and their babies. This is an update of a Cochrane review published in 2010 (Buchanan 2010). OBJECTIVES: To assess the effect of planned early birth versus expectant management for women with preterm prelabour rupture of the membranes between 24 and 37 weeks' gestation for fetal, infant and maternal well being...

BACKGROUND: Though natural surfactants (SF) are clinically superior to protein-free synthetic preparations, CHF-5633, a synthetic SF containing SP-B and SP-C analog peptides is a potential alternative to natural SF for treating neonatal respiratory distress syndrome (RDS). Nevertheless, information is lacking regarding the safety of this new treatment for the neonatal brain. We sought to compare the cerebral and pulmonary effects of this new synthetic surfactant (CHF5633) with those of natural porcine surfactant (Cursosurf) in premature lambs with RDS...

BACKGROUND: Cesarean delivery (CD) rates have risen globally with nearly 50% of the non-indicated CDs worldwide in China and Brazil. In China's One Child Policy era (1979-2015) most deliveries were women having their only child. Family size is a major determinant of the safety of medically non-indicated CD or CD on maternal request. The goal of this study is to document CD rates, indications, and analyze the relative safety of non-indicated CD compared to SVD and intrapartum CD. METHODS: Univariate and multivariate logistic regression analyses of the association between mode of delivery and short-term maternal and perinatal outcomes were performed on a cross-section of all deliveries at 39 hospitals in 14 provinces of China in 2011, presented as adjusted odds ratio (aOR), 99% confidence intervals (CI)...

Background. Noninvasive respiratory support is considered the optimal method of providing assistance to preterm babies with breathing problems, including nasal continuous positive airway pressure (NCPAP) and humidified high flow nasal cannula (HHHFNC). The evidence of the efficacy and safety of HHHFNC used as the primary respiratory support for respiratory distress syndrome (RDS) is insufficient in low- and middle-income countries. Objective. To investigate the effect of heated humidified high flow nasal cannula on neonatal respiratory distress syndrome compared with nasal continuous positive airway pressure...
