RESUMEN
OBJECTIVE: Assess the impact of intercurrent respiratory infections in infants <29 weeks gestational age (GA). STUDY DESIGN: A retrospective cohort study of 111 infants born <29 weeks GA, controlling for bronchopulmonary dysplasia (BPD) severity and assessing pulmonary health over the first year of life through oxygen, diuretic and inhaled steroid use. RESULT: Regression analysis showed viral infections increased oxygen use (odds ratio (OR) of 15.5 (confidence interval (CI)=3.4, 71.3)). The trend test showed increasing numbers of viral infections were associated with increased oxygen (OR (95% CI)=6.4 (2.3 to 17.4), P=0.0003), diuretic (OR (95% CI)=2.4 (1.1to 5.2), P=0.02) and inhaled steroid use (OR (95% CI)=2.2 (1.003 to 5.2), P=0.049), whereas bacterial infections were not. CONCLUSION: Viral infections caused more long-term pulmonary morbidity/mortality than bacterial infections on premature lung health, even when controlling for BPD.

OBJECTIVE: To assess pulmonary outcomes of infants <29 weeks gestational age (GA), delivered at level I, II and III facilities, to identify potentially modifiable factors affecting bronchopulmonary dysplasia (BPD) severity and to assess the external generalizability of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) BPD Outcome Estimator. STUDY DESIGN: Outcomes for infants <29 weeks GA born during (2008-2010) and delivered either at an inborn level III center or in a level II or III metropolitan area hospital with transfer to a level IV center, or delivered in a distant level I or II center and then transported to a level IV center were assessed. BPD severity was compared with the NICHD Neonatal BPD Outcome Estimator. RESULT: Of 158 infants who comprised the cohort, 28 (17.8%) had no BPD, 39 (24.2%) had mild BPD, 45 (28.7%) had moderate BPD, 31 (19.7%) had severe BPD and 15 (9.6%) died at ≤36 weeks post menstrual age. Site of birth did not predict severe BPD or death. Receiver operator characteristic curves showed fair predictability for none/mild and severe BPD. CONCLUSION: BPD severity was not dependent on site of birth. The NICHD BPD outcome estimator provides fair prediction for extreme outcomes.

We present a case of a late-preterm infant admitted for suspected cyanotic heart disease who was found to have a thrombosed ductus arteriosus. Maternal history was significant for heterozygosity for Factor V Leiden, treated with enoxaparin during her pregnancy, and congenital hearing loss. The neonate did not have a Factor V Leiden mutation detected, but was found to have a heterozygous mutation within the MFTHR gene. He was treated with anticoagulation, with improving hemodynamics measured by echocardiogram. This case presents a rare disease, which is potentially fatal if diagnosis is delayed.
