BACKGROUND: Most preterm infants are exposed to a variable duration of antibiotic therapy after birth despite negative cultures. Data is emerging about the risks of prolonged antibiotics. We sought to assess the association between length of initial antibiotic course and neonatal outcomes in a cohort from a single large perinatal centre. METHODS: Retrospective cohort study of prospectively collected data on all infants with a birth weight of less than 1250 g hospitalized in our NICU in a 4-year window and who had negative blood and CSF cultures in the first 2 days of life...

OBJECTIVE: Explore the role of red blood cell donor sex on preterm infant neonatal outcomes. STUDY DESIGN: In a retrospective, exploratory, cohort study, the hospital blood bank database was queried for units of blood released to neonatal intensive care unit patients in 2009-2010. The state blood center provided donor sex, and a department database provided neonatal characteristics and morbidities. Comparisons were made for 2 groups: those who ever received female blood and those who did not...

BACKGROUND: It is unclear whether a neonatal or a fetal growth standard is a better predictor of adverse in-hospital newborn outcomes. OBJECTIVE: We aimed to evaluate and compare the power of birth weight for gestational age to predict adverse neonatal outcomes using neonatal and fetal growth charts. Gestational age specific birth weight was examined either as a centile score or as a binary indicator for birth weight below the 10th centile (small for gestational age) using three fetal growth charts (National Institute of Child Health and Human Development, World Health Organization, and Intergrowth-21st ) and one neonatal sex-specific birth weight chart...

OBJECTIVE: Calprotectin is an antimicrobial protein found in stool when released by granulocytes. We sought to create stool calprotectin reference ranges in preterm neonates and to evaluate whether levels exceeding the upper reference interval are diagnostic for necrotizing enterocolitis (NEC). STUDY DESIGN: Stool calprotectin was measured in premature neonates without gastrointestinal pathology to create reference intervals. For comparison, levels from infants undergoing "rule out NEC" evaluations were plotted on these reference intervals...

Lactoferrin is one of the most represented and important bioactive proteins in human and mammal milk. In humans, lactoferrin is responsible for several actions targeting anti-infective, immunological, and gastrointestinal domains in neonates, infants, and young children. Evidence-based data vouch for the ability of supplemented lactoferrin to prevent sepsis and necrotizing enterocolitis in preterm infants and to reduce the burden of morbidity related to gastrointestinal and respiratory pathogens in young children...

BACKGROUND: Necrotizing enterocolitis (NEC) persists as the most common and serious gastrointestinal disorder among premature infants. Lactococcus lactis (LL), a lactic acid producing bacteria commonly found in buttermilk and cheese products, has several unique properties making it an ideal probiotic for neonates. We evaluated if the probiotic LL prevents development of NEC in a preterm rabbit model with Cronobacter sakazakii (CS). METHODS: Two-day preterm New Zealand white rabbit pups were randomly assigned to three diets: control (no additives), CS, and CS+LL...

This state-of-the-art review article aims to highlight the most recent evidence about the therapeutic options of surgical necrotizing enterocolitis, focusing on the molecular basis of the gut-brain axis in relevance to the neurodevelopmental outcomes of primary peritoneal drainage and primary laparotomy. Current evidence favors primary laparotomy over primary peritoneal drainage as regards neurodevelopment in the surgical treatment of necrotizing enterocolitis. The added exposure to inhalational anesthesia in infants undergoing primary laparotomy is an additional confounding variable but requires further study...

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)...

Preterm infants are a special group, and related severe neurological, respiratory, and digestive disorders have high disability/fatality rates. Allogeneic cell transplantation may be an effective method for the prevention and treatment of these diseases. At present, animal studies have been conducted for allogeneic cell transplantation in the treatment of hypoxic-ischemic encephalopathy, bronchopulmonary dysplasia, and necrotizing enterocolitis. The main difficulty of this technique is graft-versus-host reaction (GVHR), and successful induction of immune tolerance needs to be achieved in order to solve this problem...

BACKGROUND: Necrotizing enterocolitis (NEC) continues to be a devastating condition among preterm infants. Nitric oxide, which is synthesized in the intestine by endothelial nitric oxide synthase (eNOS), acts as a potent vasodilator and antioxidant within the mesentery and may play a role in prevention of NEC. We hypothesized that loss of endothelial nitric oxide would worsen both intestinal and associated lung injury and increase local and systemic inflammation during experimental NEC...

Several treatments have been proposed to shorten the time to the attainment of full oral feeding (FOF) for premature infants, but there are only a few evaluation methods useful in estimating predictors of this period. We investigated whether specific items within the disorganized sucking patterns described by the Neonatal Oral-Motor Assessment Scale (NOMAS) could estimate the time to FOF in preterm infants with feeding difficulty. Preterm infants diagnosed with a disorganized sucking pattern in the NOMAS evaluation before 50 weeks of postmenstrual age were included...

BACKGROUND & AIM: The prevention of necrotizing enterocolitis (NEC) is a primary goal in the care of preterm and low birth-weight infants. Donor-banked milk (DM)-feeding has been reported to have a protective effect towards NEC with respect to formula-feeding. All the meta-analysis published so far, have been focused on the protective effect of DM on the overall risk of NEC, none of them focused on the risk of the most severe cases on NEC only, that are those requiring surgery. We conducted a meta-analysis of available evidences on the risk of developing surgical cases of NEC in DM-fed preterm and/or low birth weight infants with respect to those formula-fed...
