The purpose of this study was to describe the development and initial implementation of a single-center prospective cohort study of children with SB and their parents living in South Korea and to describe demographics, clinical outcomes, psychosocial characteristics, and family data for this cohort.

Methods: This cohort was established through expert panel formation, identification of health indicators based on the Life Course Model for Spina Bifida, creation of a cohort database system, and quality control planning.

Antibiotic Exposure and Risk of Parkinson Disease in South Korea: A Nationally Representative Retrospective Cohort Study.

Background And Objectives: Recent studies have suggested that antibiotics could be a contributing factor to Parkinson disease (PD), but validation in other population cohorts, such as Asians, is needed. This study examined the association between exposure to antibiotics and PD risk in the Korean population.

Methods: Using the National Health Insurance Service (NHIS) database, this population-level cohort research study from Korea included 298,379 people aged 40 years and older who underwent a national health examination in 2004-2005.

Disruption of bioenergetics enhances the radio-sensitivity of patient-derived glioblastoma tumorspheres.

Background: Despite available treatment approaches, including surgical resection along with chemotherapy and radiotherapy, glioblastoma (GBM), the most prevalent primary brain tumor, remains associated with a grim prognosis. Although radiotherapy is central to GBM treatment, its combination with bioenergetics regulators has not been validated in clinical practice. Here, we hypothesized that bioenergetics regulators can enhance the radio-sensitivity of GBM tumorspheres (TSs).

Cost-effectiveness of strengthening blood pressure classification in South Korea: comparing the 2017 ACC/AHA and KSH guidelines.

Background: Hypertension is a significant risk factor for cardiovascular disease (CVD), with hypertension-related deaths increasing annually. While South Korea uses the Korean Society of Hypertension (KSH) guideline of 140/90 mmHg, the American College of Cardiology (ACC) and American Heart Association (AHA) updated their guidelines in 2017 to 130/80 mmHg. This study evaluates the cost-effectiveness of transitioning to the 2017 ACC/AHA guidelines by estimating early treatment impacts and potential CVD risk reduction.

A 5-Year Mortality Prediction Model for Prostate Cancer Patients Based on the Korean Nationwide Health Insurance Claims Database.

Background: Prostate cancer is the fourth most common cancer and eighth leading cause of cancer-related mortality worldwide. Its incidence is increasing in South Korea. This study aimed to investigate a predictive model for the 5-year survival probability of prostate cancer patients in a Korean primary care setting.

Long-term impact of socioeconomic status after acute myocardial infarction in Korea.

Background And Aims: Socioeconomic status (SES) is known to impact the prognosis of acute myocardial infarction (AMI). However, due to the limited scope of previous studies, this study aimed to investigate the impact of SES on the prognosis of AMI patients within the Korean national healthcare insurance system.

Methods And Results: A retrospective cohort study included patients who were diagnosed with AMI between 2007 and 2008 from the Korean National Health Insurance Service and underwent a national health check-up program.

Synergistic combination of perphenazine and temozolomide suppresses patient-derived glioblastoma tumorspheres.

Background: Glioblastoma (GBM), a primary malignant brain tumor, has a poor prognosis, even with standard treatments such as radiotherapy and chemotherapy. In this study, we explored the anticancer effects of the synergistic combination of perphenazine (PER), a dopamine receptor D2/3 (DRD2/3) antagonist, and temozolomide (TMZ), a standard treatment for GBM, in patient-derived human GBM tumorspheres (TSs).

Methods: The biological effects of the combination of PER and TMZ in GBM TSs were assessed by measuring cell viability, ATP, stemness, invasiveness, and apoptosis.

Effect of comorbidities on mortality in patients with nontuberculous mycobacterial infection in Korea: National Health Insurance Service-National Sample Cohort data.

Patients with nontuberculous mycobacteria (NTM) infection have multiple comorbidities, but the impact of comorbidities on mortality are not well known. We aimed to compare the mortality between people with and without NTM infection and associated comorbidities and their prognostic value on mortality using National Health Insurance Service-National Sample Cohort data from 2006 to 2019. In this matched cohort study, people with and without NTM infection aged 20-89 years were matched 1:4 by sex, age, region, and income.

Differential associations of physical job demands with cognitive impairment in Korean workers aged 45 and older: a 14-year longitudinal study using the Korean Longitudinal Study of Aging (KLoSA).

Objectives: To investigate the association between subelements of physical job demands and cognitive impairment risk in middle-aged and older workers in Korea.

Design: Longitudinal study using eight waves (2006-2020) of the Korean Longitudinal Study of Aging.

Setting: Nationally representative sample of the Korean population aged 45 years and older.

Impact of Respiratory Motion on the Quantification of Pediatric Hepatic Steatosis Using Two Different Ultrasonography Machines.

Purpose: This study aimed to investigate the effect of respiratory motion on hepatic steatosis quantification using ultrasound attenuation imaging (ATI) or ultrasound-guided attenuation parameter (UGAP) in pediatric patients.

Materials And Methods: Pediatric patients (aged ≤18 years) who underwent liver ultrasonography (US) with ATI or UGAP between May 2022 and February 2023 were included retrospectively. Median, interquartile range (IQR), and IQR/median values were calculated in both free-breathing (FB) and breath-holding (BH) states.

REM sleep without atonia and neurocognitive function in isolated REM sleep behaviour disorder: Cross-sectional and longitudinal study.

This study investigated the relationship between rapid eye movement sleep without atonia and cognitive profiles in individuals diagnosed with isolated rapid eye movement sleep behaviour disorder, assesssing both cross-sectional associations and their link to phenoconversion in a longitudinal follow-up. Participants underwent video-polysomnography, neurological examination, neuropsychological tests and structured interviews to confirm isolated rapid eye movement sleep behaviour disorder. Rapid eye movement sleep without atonia was manually scored using the Montreal method, and participants were categorized into either high or low electromyography activity groups, based on their tonic and phasic electromyography activities.

Predicting Successful Weaning through Sonographic Measurement of the Rapid Shallow Breathing Index.

Diaphragmatic dysfunction correlates with weaning failure, highlighting the need to independently assess the diaphragm's effects on weaning. We modified the rapid shallow breathing index (RSBI), a predictor of successful weaning, by incorporating temporal variables into existing ultrasound-derived diaphragm index to create a simpler index closer to tidal volume. We conducted a prospective observational study of patients who underwent a spontaneous breathing trial in the medical intensive care unit (ICU) at Severance Hospital between October 2022 and June 2023.

Promoter mutation-independent TERT expression is related to the immune-enriched milieu in papillary thyroid cancer.

Telomerase reverse transcriptase promoter mutation (pTERT MT) promotes human carcinogenesis via aberrant expression of telomerase reverse transcriptase (TERT). However, the tumorigenic impact of TERT expression independent of pTERT MT remains unclear despite numerous mechanisms of TERT being suggested. To tackle this issue, we employed comprehensive bioinformatics to assess biological variations noticed among different TERT expression mechanisms.
