Metabolic health, obesity, and prognosis in chronic obstructive pulmonary disease

Metabolic syndrome is a common comorbidity in chronic obstructive pulmonary disease (COPD), yet its long-term impact on survival and exacerbations remains controversial. We investigated whether metabolic health status and body mass index (BMI) influence mortality and the rate of...

Explainable machine learning on repeated screening data for risk-stratified diabetes care: a dual-level interpretability approach

In South Korea, national health screening intervals are determined by occupational category: typically, annual screening for non-office workers and biennial screening for office workers. To enable proactive prevention, it is critical to understand how these screening intervals an...

Diagnostic Utility of the Albumin-to-Globulin Ratio for Kawasaki Disease in Children Presenting to the Emergency Department

OBJECTIVES: Early diagnosis of Kawasaki disease (KD) is essential to prevent coronary artery complications but may be challenging in the emergency department (ED), particularly in patients who do not meet the complete clinical criteria. Although hypoalbuminemia is commonly used a...

Risk of peripheral artery disease following ankylosing spondylitis, 2012–2023: a nationwide cohort study in South Korea

OBJECTIVE: Ankylosing spondylitis (AS) is a chronic inflammatory disease linked to systemic vascular complications. Evidence regarding the association between AS and peripheral artery disease (PAD) remains limited. We investigated whether patients with AS have an increased risk o...

Depression as a Risk of Lung Cancer in Women: a Nationwide Cohort Study

BACKGROUND: Lung cancer is a leading contributor to global cancer incidence and mortality. While depression has been linked to adverse health behaviors, particularly tobacco smoking, that may elevate cancer risk, the direct relationship between depression and lung cancer remains...

Three-Year Outcomes of Drug-Eluting Stents, Drug-Coated Balloons, and Non-Drug-Eluting Devices in Native Femoropopliteal Artery Disease: An Analysis of the K-VIS ELLA Registry

Background: Although drug-eluting devices have demonstrated improved efficacy in femoropopliteal artery (FPA) disease, evidence on their long-term clinical outcomes in realworld practice remains limited.Methods: Using data from the multicenter Korean Vascular Intervention Society...

Data for "A Fourier-Space Approach to Physics-Informed Magnetization Reconstruction from Nitrogen-Vacancy Measurements"

Measured NV field maps, synthetic ground truth and all 159 reconstructions shown in the main text and the Supplemental Material of the paper (Phys. Rev. Lett., DOI 10.1103/nc5g-3yw9). Each reconstruction directory holds config.json, result.json, m_star.npy, h_proj.npy, h_dem.npy...

Discordant Antitumor Efficacy with Compromised Survival in High-Risk Unresectable Hepatocellular Carcinoma

Background/Objectives: Real-world data in high-risk patients remain limited; this study evaluated survival, safety, and prognostic factors in this patient group. Methods: This multicenter study retrospectively reviewed 783 patients who received Ate/Bev from 2022–2024 across South...

Remimazolam Versus Propofol for Anesthesia with I-Gel Airway Management During Coil Embolization of Unruptured Intracranial Aneurysms: A Randomized Controlled Trial

Background: Maintaining hemodynamic stability is crucial during coil embolization of unruptured intracranial aneurysms. Remimazolam has been suggested to exert less cardiovascular depression than propofol and may therefore provide more stable hemodynamic conditions. This study co...

Outcomes of Asian and Caucasian patients with type A aortic intramural haematoma: a multicentre registry analysis

Background Outcomes of aortic intramural haematoma (IMH) have shown disparities between Asian and Caucasian patients. We evaluated the heterogeneity of treatment effects in Asian and Caucasian patients with type A IMH. Methods This multicentre registry included individual patient...

Prognostic Role of Adverse Events in a Worldwide Population of Patients with Biliary Tract Cancer Treated with Chemo-Immunotherapy

Background: Biliary tract cancers (BTCs) are aggressive malignancies with limited treatment options. The addition of durvalumab or pembrolizumab to cisplatin–gemcitabine improves overall survival (OS), but validated biomarkers of benefit remain limited. Immune-mediated adverse ev...

Age- and sex-adjusted genomic differences between Korean and Beat AML cohorts

Genomic profiling plays a central role in risk stratification and therapeutic decision-making in acute myeloid leukemia (AML), yet the clinical implications of population-specific genomic architectures remain incompletely defined. We conducted a prospective, multicenter study of...

Drosophila pyruvate kinase links metabolic state with circadian output via TARANIS and PDF

Abstract The circadian clock generates ∼24-hour rhythms that anticipate daily environmental changes. Circadian clock and glucose metabolism are tightly interconnected, and both are disrupted in aging and disease. To examine how glucose hypometabolism impacts circadian rhythm, we...

Predictors of Early Versus Late Atrial Tachyarrhythmia Recurrence After Cryoballoon Ablation by Atrial Fibrillation Type

ABSTRACT Introduction Patient characteristics and predictors of early (ERAT) and late (LRAT) recurrence of atrial tachyarrhythmia by atrial fibrillation (AF) type after cryoballoon ablation (CBA) remain poorly defined. Methods Using the Korean Heart Rhythm Cryoballoon Registry (1...

Nonreciprocal Vortex Pinning and Re-entrant Superconductivity through Niobium Interface Design

Abrikosov vortex motion in type-II superconductors generates finite resistance under applied current, limiting practical use. Traditional suppression via defect engineering is complex and hard to reproduce. Here, we show that interfacial engineering-specifically, tuning the penet...

Changing Clinical Characteristics, Diagnostic Patterns, and Outcomes of Tuberculosis in South Korea: The Korean Tuberculosis Cohort, 2019-2024

BACKGROUND: Tuberculosis (TB) remains a public health concern in South Korea despite declining national notifications. We evaluated temporal changes in clinical characteristics, diagnostic patterns, and treatment outcomes in the Korean Tuberculosis Cohort (KTBC) from 2019 to 2024...

Affine-Half Extensions of Partial-Spread Minimal Binary Linear Codes with Explicit Weight Distributions

In this paper, we derive complete weight distributions and solve constrained optimization problems for affine-half coordinate extensions of a known family of partial-spread minimal binary codes. The extended code has length 2m+2m−1−1 and dimension m+1, and it remains minimal. The...

Stereotactic body radiation therapy for hepatocellular carcinoma: 2026 expert consensus-based practical recommendation of the Korean Liver Cancer Association

Stereotactic body radiation therapy (SBRT) is a noninvasive, high-precision radiation technique that delivers a high dose to the tumor in a limited number of fractions, typically five or fewer, and is increasingly used as a curative-intent option for hepatocellular carcinoma (HCC...

Korean Clinical Practice Guidelines for Rehabilitation in Critically Ill Patients and Post-Intensive Care Syndrome

Background: Survivors of critical illness commonly experience persistent physical, cognitive, and psychological impairments, collectively known as post–intensive care syndrome. Although intensive care unit (ICU) rehabilitation is now recognized as an important part of recovery af...
