Growth phenotypes of very low birth weight infants for prediction of neonatal outcomes from a Brazilian cohort: comparison with INTERGROWTH.

Objective: To assess the predictive value of selected growth phenotypes for neonatal morbidity and mortality in preterm infants < 30 weeks and to compare them with INTERGROWTH-21 (IG21).

Method: Retrospective analysis of data from the Brazilian Neonatal Research Network (BNRN) database for very low birth weight (VLBW) at 20 public tertiary-care university hospitals.

Outcome: the composite neonatal morbidity and mortality (CNMM) consisted of in-hospital death, oxygen use at 36 weeks, intraventricular hemorrhage grade 3 or 4, and Bell stage 2 or 3 necrotizing enterocolitis.

Evaluation of the effectiveness of antenatal corticoid in preterm twin and single pregnancies: a multicenter cohort study.

Background: The effects of antenatal corticosteroids (ANSs) on twins are not well established.

Objective: To determine the impact of ANS use according to the number of fetuses.

Methods: Retrospective cohort study of newborns between 23 and 33 weeks of gestational age, birth weight from 400 to 1499 g, without malformations, delivered at 20 public university hospitals from 2010 to 2014.

Early Empiric Antibiotic Use Is Associated With Delayed Feeding Tolerance in Preterm Infants: A Retrospective Analysis.

The causative factors of neonatal feeding intolerance are poorly understood, but potentially related to clinical practices such as empiric antibiotic usage. The objective of this study was to evaluate whether early empiric antibiotic exposure negatively affects preterm infants' enteral feeding tolerance. Data from infants without risk factors for sepsis, 500 to 1499 g birth weight and 24 to 34 weeks gestational age were analyzed.

Death or survival with major morbidity in VLBW infants born at Brazilian neonatal research network centers.

Objective: To analyze unfavorable outcomes at hospital discharge of preterm infants born at Brazilian public university centers.

Methods: Prospective cohort of 2646 inborn infants with gestational age 23-33 weeks and birth weight 400-1499 g, without malformations, born at 20 centers in 2012-2013. Unfavorable outcome was defined as in-hospital death or survival at hospital discharge with ≥1 major morbidities: bronchopulmonary dysplasia (BPD) at 36 corrected weeks, intraventricular hemorrhage (IVH) grades 3-4, periventricular leukomalacia (PVL) or surgically treated retinopathy of prematurity (ROP).
