BACKGROUND: Although late-onset circulatory collapse (LCC) is widely recognized in Japan, its etiology and the reason for center variation in its incidence remain unclear. This study's objectives were to identify the perinatal and neonatal factors related to LCC and to estimate the factors related to the center variation in the incidence of LCC. METHODS: Extremely preterm infants born between 2008 and 2012 who were registered in the database of the Neonatal Research Network, Japan were retrospectively analyzed...

RATIONALE: Mechanical ventilation with O2 -rich gas (MV-O2 ) inhibits alveologenesis and lung growth. We showed that MV-O2 increases elastase activity and apoptosis in lungs of newborn mice; elastase inhibition by elafin suppressed apoptosis and enabled lung growth. In pilot studies, MV-O2 reduced lung expression of pro-survival factors, pEGFR and Klf4. OBJECTIVES: Determine if apoptosis and lung growth arrest evoked by MV-O2 reflect disrupted pEGFR-Klf4 signaling, which elafin treatment preserves...

AIM: More infants born extremely preterm (EPT) are surviving, but major neonatal morbidities are consistently high. This study examined the impact of bronchopulmonary dysplasia (BPD), brain injuries and severe retinopathy of prematurity (ROP) on adolescents who were born EPT. METHODS: We focused on EPT infants born at 23-25 weeks at the Swedish university hospitals in Uppsala and Umeå from January 1992 to December 1998. The poor outcome data covered 140/142 who survived to 36 weeks and the chronic conditions data reported by parents covered 132/134 still alive at 10-15 years...

REVIEW
Jennifer Shepherd, Kai-Hsiang Hsu, Shahab Noori
Although patent ductus arteriosus is essential in fetal life, interventions to close or minimize the adverse hemodynamic effects associated with the left-to-right shunt are often needed after birth, especially in extremely premature infants. However, there are clinical conditions where maintaining patency of the ductus is essential for survival. In this article we discuss use of prostaglandin E1 in the management of congenital heart defects, pulmonary hypertension and left ventricular failure in early neonatal period...

Background and objectives: Advances in neonatal care promoted increased survival rates of preterm infants, with a consequent increase in the number of children affected by retinopathy of prematurity (ROP). This study estimates the incidence of ROP and evaluates potential risk factors associated. Methods: A retrospective cohort study of preterm infants born in a tertiary neonatal intensive care unit was conducted from March 2005 to August 2015. Six hundred and thirty-nine newborns were included based on the following criteria: infants born with less than 32 weeks' gestation or birth weight below 1500 g; or neonates born with 32-37 weeks' gestation or birth weight above 1500 g and any of the following associated: multiple gestation, respiratory distress syndrome, sepsis, blood transfusions or intraventricular hemorrhage...

OBJECTIVE: Articles previously published by Sullivan et al. and Cristofalo et al. were reanalyzed using the proportion of cow milk-based nutrition received to determine whether that affected clinical outcomes during hospitalization for infants birth weight 500-1250 g. Abrams et al. showed in the same cohort incidences of necrotizing enterocolitis (NEC), NEC requiring surgery and sepsis increased proportionally to the amount of dietary cow milk. METHODS: The data from the two studies conducted under essentially the same protocol were combined yielding a cohort of 260 infants receiving a diet ranging from 0% to 100% cow milk...

BACKGROUND: Most clinical guidelines state that with early preterm premature rupture of membranes, obstetric and pediatric teams must share a realistic and individualized appraisal of neonatal outcomes with parents and consider their wishes for all decisions. However, we currently lack reliable and relevant data, according to gestational age at rupture of membranes, to adequately counsel parents during pregnancy and to reflect on our policies of care at these extreme gestational ages...

Neonatal hypertension is increasingly recognized as dramatic improvements in neonatal intensive care, advancements in our understanding of neonatal physiology, and implementation of new therapies have led to improved survival of premature infants. A variety of factors appear to be important in determining blood pressure in neonates, including gestational age, birth weight, and postmenstrual age. Normative data on neonatal blood pressure values remain limited. The cause of hypertension in an affected neonate is often identified with careful diagnostic evaluation, with the most common causes being umbilical catheter-associated thrombosis, renal parenchymal disease, and chronic lung disease...

Extremely preterm infants are at higher risk of pulmonary (PH) and intraventricular (IVH) haemorrhage during the transitioning physiology due to immature cardiovascular system. Monitoring of haemodynamics can detect early abnormal circulation that may lead to these complications. We described time-frequency relationships between near infrared spectroscopy (NIRS) cerebral regional haemoglobin oxygen saturation (CrSO2 ) and preductal peripheral perfusion index (PI), capillary oxygen saturation (SpO2 ) and heart rate (HR) in extremely preterm infants in the first 72 h of life...

Bronchopulmonary dysplasia remains the main complication of extreme preterm birth. Research over the past 10 years suggests the potential for stem cell-based therapies to prevent and/or restore organ damage in extreme preterm infants. Mesenchymal stromal cells, in particular, have advanced as the forerunner among various cell therapies based on very promising preclinical studies in animal models of neonatal lung injury. Early phase clinical trials are now underway to determine the safety and feasibility of this cell therapy in preterm infants at risk of developing bronchopulmonary dysplasia...
