This study evaluated the association between the presence of an atrial septal defect (ASD) and the odds of developing bronchopulmonary dysplasia (BPD) in premature infants. The presence of an ASD was associated with an increased odds of BPD in this cohort. Future trials should consider ASD as a potentially modifiable risk factor in this vulnerable population.

This study identified factors associated with prolonged maternal breast milk (BM) provision in very low birth weight (VLBW) infants. Results suggest that maternal-infant demographic and clinical factors and household neighborhood socioeconomic characteristics were associated with provision of maternal BM at 30 postnatal days to VLBW infants. Identification of these factors allows providers to anticipate mothers’ needs and develop tailored interventions designed to improve rates of prolonged maternal BM provision and infant outcomes.

This study evaluated the association between furosemide exposure and patent ductus arteriosus (PDA) in a large, contemporary cohort of hospitalized infants with very low birth weight (VLBW). Furosemide exposure was not associated with increased odds of PDA treatment in hospitalized infants of VLBW. Further studies are needed to characterize the efficacy and safety of furosemide in premature infants.

In very low birth weight infants, persistence of a patent ductus arteriosus results in morbidity and mortality. Therapies to close the ductus are effective, but clinical outcomes may depend on the accuracy of diagnosis and the timing of administration. The objective of the present study was to characterise the association between early echocardiography, therapy for patent ductus arteriosus, and outcomes in very low birth weight infants.

Late-onset sepsis (LOS) is an important cause of death and neurodevelopmental impairment in premature infants. The purpose of this study was to assess overall incidence of LOS, distribution of LOS-causative organisms and center variation in incidence of LOS for extremely premature infants over time.

This study characterized in-hospital outcomes of premature infants diagnosed with severe bronchopulmonary dysplasia (BPD). A majority of infants diagnosed with severe BPD were discharged home by 44 weeks of postmenstrual age. These results may inform discussions with families regarding the expected hospital course of infants diagnosed with severe BPD.

To assess how neonatal intensive care units followed the American Academy of Pediatrics guidelines for use of dexamethasone in preterm infants by evaluating respiratory support at the time of dexamethasone administration. This is an observational study of infants discharged from one of 290 neonatal intensive care units from 2003 to 2010. The cohort included very low birth weight (<1500 g birth weight) infants born at ≤32 weeks gestational age. The main outcome was respiratory support at time of exposure to dexamethasone.

Fluconazole is an effective agent for prophylaxis of invasive candidiasis in premature infants. The objective of this study was to characterize the population pharmacokinetics (PK) and dosing requirements of fluconazole in infants with birth weights of <750 g. As part of a randomized clinical trial, infants born at <750 g birth weight received intravenous (i.v.) or oral fluconazole at 6 mg/kg of body weight twice weekly.

Immunization of extremely low birth weight (ELBW) infants in the neonatal intensive care unit (NICU) is associated with adverse events including fever and apnea/bradycardia in the immediate post-immunization period. This presents a diagnostic dilemma for clinicians, leading to the potential for immunization delay and sepsis evaluations. The goal of this study is to compare the incidence of sepsis evaluations, need for increased respiratory support, intubation, seizures, and death among immunized ELBW infants in the 3 days pre- and post-immunization.

Histamine-2 receptor (H2) blockers are often used in very low birth weight infants despite lack of population specific efficacy and safety data. We sought to describe safety and temporal trends in histamine-2 receptor (H2) blocker use in hospitalized very low birth weight (VLBW) infants.
