Survival and Risk Factors for Mortality in Infants With Congenital Heart Disease in South Korea.

Background/aim: The survival of patients with congenital heart disease (CHD) has dramatically improved over recent decades. However, a disparity exists depending on the country and medical system. This study aimed to analyze the survival of infants with CHD until the age of 18 years using large-scale population data in South Korea and investigate the effect of neonatal conditions at birth.

Trends in recurrence of primary spontaneous pneumothorax in young population after treatment for first episode based on a nationwide population data.

The aim of this study is to identifying post treatment recurrence rates in pneumothorax patients under 35 and without any comorbidities according to the treatment types, gender, and age categories based on nationwide population data. Clinical information of pneumothorax patients was extracted from the Korean National Health Insurance Service (NHIS) database between January 2002 and December 2020. Enrolled patients were categorized into two groups; (1) Group I, those who underwent conservative management including pain relief, oxygen therapy, and closed thoracostomy, and (2) Group II, surgical intervention.

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.

Neonatal Risk Factors for Growth Retardation in Infants With Congenital Heart Disease.

Background: While the association of congenital heart disease (CHD) and growth retardation (GR) is known, data remain limited. This study investigated the incidence of GR and its neonatal risk factors in patients with CHD using nationwide population-based claims data.

Method: The study population was extracted from Korean National Health Insurance Service claims data from January 2002 to December 2020.

Prognostic Significance of Initial Absolute Lymphocyte Count in Adjuvant Radiotherapy for Pancreatic Adenocarcinoma.

Background: This study aimed to investigate the impact of absolute lymphocyte count (ALC) on clinical outcomes in patients treated with adjuvant RT with or without chemotherapy for pancreatic adenocarcinoma.

Methods: From 2001 to 2015, 68 patients underwent curative surgery followed by adjuvant RT. Chemotherapy was administered concurrently or sequentially with RT.
