Association between maternal coronavirus disease 2019 and transient tachypnea of the newborn: a single-center study.

Background: Limited clinical reports have investigated the effects of maternal coronavirus disease 2019 (COVID-19) on fetuses and neonates.

Purpose: This retrospective study aimed to assess the impact of maternal COVID-19 on neonates during the perinatal period, including neonatal clinical outcomes, versus the outcomes of neonates of mothers without COVID-19.

Methods: Neonates born to COVID-19-infected mothers at the National Health Insurance Service Ilsan Hospital between February 2021 and March 2022 were included.

Long-term outcomes of preterm infants in the first 6 years of life: a nationwide population-based study in Korea.

Unlabelled: This study examined the relationship between gestational age and long-term outcomes up to 6 years of age using population-based big data from the National Health Insurance Service in Korea. This retrospective observational cohort study used data from the National Health Information Database (2011-2017). All children born in Korea during 2011 (January 1-December 31) were eligible and were followed up until 2017.

Medical Utilization and Costs in Preterm Infants in the First 6 Years of Life After Discharge From Neonatal Intensive Care Unit: A Nationwide Population-Based Study in Korea.

Background: The improvement in the survival rate of preterm infants has paradoxically raised the risk of morbidities in childhood. Our objectives were to assess the medical utilization and costs in preterm infants following discharge from the neonatal intensive care unit in the first 6 years of life.

Methods: We conducted a population-based study using the National Health Information Database (2011-2017) provided by the Korean National Health Insurance Service (NHIS).

Two Cases of SARS-CoV-2-Positive Mothers and Their Newborns in Korea.

It is unclear how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects pregnant women and their fetuses or newborns. We report two infants born to mothers with coronavirus disease 2019 (COVID-19) in Korea. The first case was a healthy female baby born at 39 weeks' gestation from a mother diagnosed with COVID-19.

Long-term cognitive, executive, and behavioral outcomes of moderate and late preterm at school age.

Background: There is increasing concern that moderate preterm (32-33 weeks' gestation) and late preterm (34-36 weeks' gestation) birth may be associated with minor neurodevelopmental problems affecting poor school performance.

Purpose: We explored the cognitive function, cognitive visual function, executive function, and behavioral problems at school age in moderate to late preterm infants.

Methods: Children aged 7-10 years who were born at 32+0 to 36+6 weeks of gestation and admitted to the neonatal intensive care unit from August 2006 to July 2011 at the National Health Insurance Service Ilsan Hospital were included.

Intrapleural urokinase therapy in a neonate with pleural empyema.

Pleural empyema is rare in neonates, and treatment with systemic antibiotics and tube drainage may fail because of the thick viscous fluid, bacterial products with fibrin deposition, and multiple loculations. Intrapleural fibrinolytic therapy with urokinase is an effective and non-invasive treatment option that avoids surgical intervention, although its use in neonates has not been studied extensively. In this report, we describe the case of a 13-day-old male neonate with Escherichia coli sepsis and pneumonia, which rapidly progressed to parapneumonic effusion and pleural empyema.

Perinatal and neonatal predictors of developmental coordination disorder in very low birthweight children.

Objective: To identify perinatal and neonatal risk factors associated with developmental coordination disorder (DCD) in very low birthweight children (VLBW: <1250 g).

Design: Retrospective design with prospectively collected cohort.

Setting: Neonatal Follow-Up Program, Vancouver, Canada.
