Objective Compare delivery room practices and outcomes of infants born at less than 32 weeks' gestation or less than 1,500 g who have plastic wrap/bag placement simultaneously during placental transfusion to those receiving plastic wrap/bag placement sequentially following placental transfusion. Study Design Retrospective analysis of data from a multisite quality improvement initiative to refine stabilization procedures pertaining to placental transfusion and thermoregulation using a plastic wrap/bag. Delivery room practices and outcome data in 590 total cases receiving placental transfusion were controlled for propensity score matching and hospital of birth. Results The simultaneous and sequential groups were similar in demographic and most outcome metrics. The simultaneous group had longer duration of delayed cord clamping compared with the sequential group (42.3 ± 14.8 vs. 34.1 ± 10.3 seconds, p < 0.001), and fewer number of times cord milking was performed (0.41 ± 1.26 vs. 0.86 ± 1.92 seconds, p < 0.001). The time to initiate respiratory support was also significantly shorter in the simultaneous group (97.2 ± 100.6 vs. 125.2 ± 177.6 seconds, p = 0.02). The combined outcome of death or necrotizing enterocolitis in the simultaneous group was more frequent than in the sequential group (15.3 vs. 9.3%, p = 0.038); all other outcomes measured were similar. Conclusion Timing of plastic wrap/bag placement during placental transfusion did affect duration of delayed cord clamping, number of times cord milking was performed, and time to initiate respiratory support in the delivery room but did not alter birth hospital outcomes or respiratory care practices other than the combined outcome of death or necrotizing enterocolitis. Key Points Plastic bag placement during placental transfusion is effective in stabilization of preterms. Plastic bag placement after placental transfusion is effective in stabilization of preterms. Plastic bag placement during placental transfusion and risk of death or necrotizing enterocolitis needs additional study. [ABSTRACT FROM AUTHOR]

OBJECTIVE--Emerging data demonstrate that maternal diabetes has long-term health consequences for offspring, including the development of hypertension. In adults, circulating endothelial progenitor cells (EPCs) participate in vascular repair, and EPC numbers and function inversely correlate with the risk of developing vascular disease. Therefore, our objectives were to determine whether hyperglycemia or exposure to a diabetic intrauterine environment alters EPC function. RESEARCH DESIGN AND METHODS--We used well-established clonogenic endothelial colony-forming cell (ECFC) assays and murine transplantation experiments to examine human vasculogenesis. RESULTS--Both in vitro hyperglycemia and a diabetic intrauterine environment reduced ECFC colony formation, self-renewal capacity, and capillary-like tube formation in matrigel. This cellular phenotype was linked to premature senescence and reduced proliferation. Further, cord blood ECFCs from diabetic pregnancies formed fewer chimeric vessels de novo after transplantation into immunodeficient mice compared with neonatal ECFCs harvested from uncomplicated pregnancies. CONCLUSIONS--Collectively, these data demonstrate that hyperglycemia or exposure to a diabetic intrauterine environment diminishes neonatal ECFC function both in vitro and in vivo, providing potential mechanistic insights into the long-term cardiovascular complications observed in newborns of diabetic pregnancies.

Objective: To decrease invasive mechanical ventilation exposure in the neonatal intensive care unit (NICU) in the first week of life for preterm infants with the global aim of decreasing bronchopulmonary dysplasia (BPD)., Methods: We created a quality improvement (QI) initiative to optimize early non-invasive respiratory support which launched in August 2021. Patients born at <32 weeks gestation and admitted to the NICU on non-invasive respiratory support were included., Results: Invasive mechanical ventilation exposure decreased from 38 to 25% with evidence of special cause variation beginning in August 2022. Infants born at ≥26 weeks were most impacted, with a 50% reduction, from 34 to 17%. While BPD rates decreased, there has not yet been evidence of special cause variation., Conclusion: Invasive mechanical ventilation exposure for infants born at <32 weeks gestation decreased following the creation of a QI initiative focused on optimization and standardization of early non-invasive respiratory support., (© 2024.
