Link Between History of Neonatal Jaundice and Early Childhood Allergic Diseases in South Korea.

Aim: Allergic diseases, such as asthma, allergic rhinitis (AR), and atopic dermatitis (AD) are prevalent chronic childhood conditions, with a rising incidence globally and in South Korea. Neonatal jaundice is a common perinatal condition. However, its association with the subsequent development of allergic diseases remains unclear.

Risk factors and impact of hypertriglyceridemia in preterm infants under 32 weeks of gestation: optimizing intravenous lipid emulsion infusion rates-a single center retrospective study.

Introduction: Intravenous lipid emulsions are essential for parenteral nutrition in preterm infants. However, hypertriglyceridemia (HTG) is a common complication that can lead to severe complications if left untreated. This study analyzed factors influencing HTG and the effects of reduced intravenous lipid emulsion dosages.

Evaluation of acute kidney injury in preterm infants using serum creatinine decline in comparison with KDIGO criteria.

Background: Acute kidney injury (AKI) is commonly observed in critically ill neonates; however, early identification of AKI in the first week of life is challenging due to the influence of maternal serum creatinine (SCr). An alternative criterion proposed by Gupta et al. based on SCr decline may identify additional infants at risk beyond the KDIGO definition.

Effects of subjective stress levels on learning effectiveness in high-fidelity simulation among healthcare workers.

Background: Appropriate stress reportedly influences memory gains. However, stress levels may vary across individuals and may lead to changes in vital signs as a physiological response induced by endogenous hormone secretion. The aim of this study was to evaluate the impact of high-fidelity simulation (HFS) training on cognitive performance using Perceived Stress Scale (PSS) scores as a subjective stress indicator and vital sign measurements as an objective stress indicator during Neonatal Resuscitation Program training.

Prolonged Parenteral Nutrition Increases the Risk of Comorbidities in Very-Low-Birth-Weight Infants: A Prospective National Cohort Study in South Korea.

: There has been an increase in the incidence of comorbidities among very-low-birth-weight infants (VLBWIs), including periventricular leukomalacia (PVL), bronchopulmonary dysplasia (BPD), and retinopathy of prematurity (ROP). Parenteral nutrition is essential for very-low-birth-weight infants (VLBWIs) who are born with a birth weight of less than 1500 g, but a longer duration of parenteral nutrition is known to have a risk of comorbidity, such as ROP. This study aims to investigate the relationship between the duration of parenteral nutrition and the comorbidities of the VLBWIs.

Comparison of maternal and neonatal survival exposed to humidifier disinfectants during perinatal periods: a case-series study.

A humidifier disinfectant (HD) has been prohibited by the government due to its serious effects on the human body. Several studies on the relationship between HD and lung diseases have been performed independently on children and adults. However, there have been no reports on the effects of HD exposure on pregnant women and their foetuses.

Comparison of neonatal outcomes between multiples and singletons among very low birth weight infants: the Korean Neonatal Network cohort study.

Objective: To compare neonatal outcomes between multiples and singletons among very low birth weight infants, this was a prospective cohort study that was conducted by collecting data registered in the Korean Neonatal Network database.

Methods: From January 2013 to December 2016, there were 8265 infants in the Korean Neonatal Network database, and 2958 of them were from multiples. Among them, 2636 infants were twins, 308 infants were triplets, and 14 infants were quadruplets.

Efficiency analysis by training sequence of high-fidelity simulation-based neonatal resuscitation program (NRP).

Objective: This study was conducted to find a more effective education method in a neonatal resuscitation program (NRP) using a high-fidelity simulation that has recently shown positive results in terms of its effectiveness.

Study Design: A single-blind prospective cohort study was performed. The high-fidelity simulation model was used in a formal NRP training course for trainees caring for neonatal patients.

Relationship Between Rotavirus P[6] Infection in Korean Neonates and Histo-Blood Group Antigen: a Single-Center Study.

Background: Rotaviruses are a major cause of pediatric gastroenteritis. The rotavirus P[6] genotype is the most prevalent genotype isolated from Korean neonates but has rarely been reported in other countries. Histo-blood group antigen (HBGA) is known to play an important role in rotavirus infection.

Metabolic syndrome and lung function in Korean children and adolescents: A cross-sectional study.

This study aimed to investigate whether obesity and metabolic syndrome (MetS) are associated with pulmonary function in Korean children and adolescents. Data from the 2009-2011 Korea National Health and Nutrition Examination Survey which is cross-sectional, nationwide, and representative survey were used. Adjusted regression analysis was performed to evaluate the association of obesity and MetS with lung function in children and adolescents.

Whole-genome analysis of rotavirus G4P[6] strains isolated from Korean neonates: association of Korean neonates and rotavirus P[6] genotypes.

Background: Group A rotaviruses are the major causative agents of pediatric gastroenteritis worldwide. Several studies have reported the predominance of G4P[6] rotavirus genotypes in Korean neonates, which is uncommon in other countries. Therefore, the purposes of this study were to determine the genotype constellations of complete genomes of G4P[6] rotavirus strains isolated from Korean neonates using next-generation sequencing, to compare these sequences with other G4P[6] strains in other countries, and to determine the reason for the predominance of G4P[6] genotypes in Korean neonates.

Emergence of G8P[6] rotavirus strains in Korean neonates.

Background: Rotaviruses are the major causes of pediatric gastroenteritis worldwide. The genotypic distribution of rotavirus strains shows temporal and geographical fluctuations, and knowledge of the molecular epidemiology of rotaviruses is important for the development of vaccines and diagnostic reagents. We investigated VP4 and VP7 capsid genotypes of rotaviruses isolated from 211 stool specimens collected from Korean neonates in a neonatal intensive care unit from September 2017 to March 2018.

Association between depression and asthma in Korean adults.

Purpose: Asthma is a one of the most common allergic diseases, and depression is an important comorbidity with asthma. However, little is known about the prevalence of depression in Korean adults with asthma. This study was performed to find the association between asthma and depression in Korean adults and to investigate the demographic and socioeconomic characteristics in Korean adults with asthma and with depression.
