OBJECTIVE: Impact of antenatal corticosteroid (ACS) in context of maternal body mass index (BMI) as it relates to neonatal outcomes remains unclear. We sought to evaluate effects of ACS on clinical outcomes of preterm infants based on maternal BMI. METHODS: We performed a retrospective cohort study among neonates 23-33 weeks' GA at a tertiary neonatal intensive care unit from 2011 to 2015. Outcomes of neonates exposed to any ACS and pre-pregnancy maternal BMI ≥ 25 (N = 491) were compared with maternal BMI < 25 (N = 484)...

BACKGROUND: Germinal matrix hemorrhage (GMH) is a common neurologic event with high morbidity and mortality in preterm infants. Spleen has been reported to play a critical role in inflammatory responses by regulating peripheral immune cells which contributes to secondary brain injury. METHODS: The current study investigated the mechanistic role of biliverdin reductase-A (BLVRA) in the splenic response and brain damage in neonates following a collagenase GMH model...

PURPOSE OF REVIEW: Antenatal Bartter's syndrome (aBS) is the most severe form of Bartter's syndrome, requiring close follow-up, in particular during the neonatal period, primarily because of prematurity. The recent identification of a novel and very severe form of aBS merits an update on this topic. RECENT FINDING: Despite the identification of several genes involved in Bartter's syndrome, about 20% of patients clinically diagnosed with aBS remained without genetic explanation for decades...

Preterm infants are at an increased risk of morbidity and mortality from vaccine-preventable diseases. Despite this, delays in routine immunization of preterm infants are common. Available guidelines clearly state that they should be immunized according to chronological age, irrespective of gestational age and birth weight or current weight. In this article, we try to assuage parental and provider doubts by reviewing data about immunogenicity, safety, and responses to routine immunizations in preterm infants with and without comorbidities...

Preterm infants continue to have complex medical and developmental issues after discharge from the neonatal intensive care unit. Over the past few decades there has been an increase in preterm births and a decrease in preterm mortality. Many infants are referred to follow-up clinics that specialize in neurodevelopmental assessment. Often, a community pediatrician or family practitioner provides both the medical management and observes developmental milestones of the high-risk neonate. Intense medical management, early identification of delay, and referral for developmental services may improve preterm infant outcomes...

Matthew McGovern, Jan Miletin
Maintaining optimal circulatory status is a key component of preterm neonatal care. Low-cardiac output (CO) in the preterm neonate leads to inadequate perfusion of vital organs and has been linked to a variety of adverse outcomes with heightened acute morbidity and mortality and adverse neurodevelopmental outcomes. Having technology available to monitor CO allows us to detect low-output states and potentially intervene to mitigate the unwanted effects of reduced organ perfusion. There are many technologies available for the monitoring of CO in the preterm neonatal population and while many act as useful adjuncts to aid clinical decision-making no technique is perfect...

Intraventricular haemorrhage (IVH) is characterized by bleeding of the immature subependymal germinal matrix in preterm infants, but the pathogenesis is multifactorial. IVH and posthaemorrhagic hydrocephalus (PHH) are common causes of neonatal morbidity and mortality among preterm infants. We describe a preterm male infant who was born clinically stillbirth; became moderately severe encephalopathic. He had bilateral IVH (III right and IV left) with consequent PHH. His incredible outcome following a stormy perinatal period appears intriguing...

BACKGROUND: In the past, cardiac surgery during pregnancy has been associated with high risk of adverse maternal and fetal outcomes. Therefore, this meta-analysis was done to assess the fetomaternal risk after cardiac surgery during pregnancy using cardiopulmonary bypass in more recent studies. METHODS: The Medline, Embase and Cochrane library were searched to find studies from January 1 1990 to July 31 2016 without language restriction. We selected studies that included at least four women to report fetomaternal outcomes after cardiac surgery using cardiopulmonary bypass during pregnancy...

BACKGROUND: Preterm premature rupture of membranes (PPROM) is a leading contributor to maternal and neonatal morbidity and mortality. Epidemiologic and experimental studies have demonstrated that thrombin causes fetal membrane weakening and subsequently PPROM. Although blood is suspected as the likely source of thrombin in fetal membranes and amniotic fluid of patients with PPROM, this has not been proven. Ureaplasma Parvum (U. parvum) is emerging as a pathogen involved in prematurity, including PPROM, but until now, prothrombin production directly induced by bacteria in fetal membranes has not been described...

Acute kidney injury (AKI) is a common complication in the neonatal intensive care unit that causes a high mortality of preterm infants and various chronic kidney diseases in adulthood. Preterm infants have immature development of the kidneys at birth. The kidneys continue to develop within a specific time window after birth. However, due to various factors during pregnancy and after birth, preterm infants tend to develop AKI. At present, serum creatinine and urine volume are used for the assessment of kidney injury, and their early sensitivity and specificity have attracted increasing attention...

Eveline Kaambo, Charlene W J Africa
Aerobic vaginitis (AV) is an endogenous opportunistic infection brought about by the disruption of the normal vaginal microbiota. Its early diagnosis and treatment during pregnancy may reduce the risk of negative pregnancy outcomes. The aim of this review was to report on the aerobic bacteria most prevalent in AV and to provide evidence of the threat of untreated AV on pregnancy outcomes. More than 300 papers on preterm delivery were extracted from several research domains and filtered to include only AV-associated bacteria such as Staphylococcus aureus, Enterococcus faecalis, Escherichia coli and Group B streptococci and their association with adverse pregnancy outcomes...

Arne Ohlsson, Prakeshkumar S Shah
BACKGROUND: In preterm newborns, the ductus arteriosus frequently fails to close and the infants require medical or surgical closure of the patent ductus arteriosus (PDA). A PDA can be treated surgically; or medically with one of two prostaglandin inhibitors, indomethacin or ibuprofen. Case reports suggest that paracetamol may be an alternative for the closure of a PDA. An association between prenatal or postnatal exposure to paracetamol and later development of autism or autism spectrum disorder has been reported...
