Patent ductus arteriosus (PDA) is a dramatically harmful disease in the neonatal period, in particular common in preterm infants, and our study was to determine related factors of PDA in preterm infants. A comprehensive literature review was conducted in PubMed, EMBASE, and Web of Science. The pooled odds ratio and standard mean difference were calculated to compare dichotomous and continuous variables, respectively. In addition, we also assessed the heterogeneity and publication bias and carried out sensitivity analysis for each related factor. We included 45 studies with 87,419 individuals. After the primary analysis and a series of adjustments, results showed chorioamnionitis, lower gestational age, lower birth weight, bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, respiratory distress syndrome, sepsis, surfactant treatment, ventilation, and lower platelet count had a positive correlation with PDA, while small for gestational age decreased the incidence of PDA in preterm infants. Besides, premature rupture of membranes, preeclampsia, antenatal steroids, male gender, mean platelet volume, and platelet distribution width were found to have no statistically significant relationship with PDA. Preterm infants with more immature characteristics generally have a higher likelihood to develop PDA. The prevention, diagnosis, and management of PDA may depend on these results, and effective measures can be taken accordingly.

Objective: To evaluate the incidence of thin catheter surfactant administration (TCA) failure and compare short and long-term neonatal outcomes who failed TCA or did not.
Design: Single-center retrospective cohort study. Infants between 25 and 30 weeks of gestational age with respiratory distress syndrome and receiving 200 mg/kg poractant alfa via thin catheter administration were included.

Introduction: The achievement of oral feeding competence (OFC) is a challenge in preterm infants and can be affected by several factors.
Objective: The aim of our study was to determine the time elapsed to development of OFC in very low birth weight (VLBW, weight <1500g) preterm infants and to identify factors associated with greater difficulty in achieving this skill.
Population And Methods: Observational, longitudinal and prospective study in VLBW infants over a period of 7 years (2016-2022).

Background: Respiratory Distress Syndrome (RDS) is the most common complication of preterm neonates. It remains one of the major public health concerns that contribute to neonatal mortality and morbidity, especially in Africa, where 80% of neonatal mortality is estimated to be caused by preterm complications. Nasal Continuous Positive Airway Pressure (NCPAP) ventilation is the preferred mode of RDS treatment.

Background: Preterm prelabor rupture of membranes (PPROM) before or around the limit of fetal viability is associated with serious maternal and neonatal complications including chorioamnionitis, extremely preterm birth, and pulmonary hypoplasia.
Objectives: To describe contemporary outcomes of extremely preterm infants born after prolonged periviable PPROM, and to identify perinatal factors associated with survival and survival without severe neurodevelopmental impairment (NDI).
Study Design: Among actively treated infants born alive at <27 weeks' gestational age (GA) in centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network from 2012 to 2018, the outcomes of survival and survival without severe NDI at 22-26 months' corrected age were compared between infants exposed to prolonged (≥120 hours) periviable (<24 weeks' GA) PPROM and unexposed infants born after rupture of membranes ≤18 hours before delivery or at delivery, adjusting for birth GA, sex, multiple gestation, antenatal steroids, small for gestational age (SGA), insurance, and center.
