Association of tcdB PCR Ct Values, Toxin Antigen Results, and Antibiotic Therapy with Recurrence and Prognosis in Clostridioides difficile Infection

Objectives: The clinical interpretation of molecular diagnostic results in Clostridioides difficile infection (CDI) remains challenging, particularly when polymerase chain reaction (PCR) findings are interpreted with toxin antigen results and treatment information.This study eval...

A Retrospective Multicenter Study of Measles Seropositivity in Korea from 2014 to 2024

Background: Measles is a highly contagious viral disease requiring high herd immunity.Although the Republic of Korea has maintained measles elimination through national immunization programs, sporadic cases continue to occur.We evaluated age-and period-specific measles immunity l...

Nationwide Multicenter Laboratory-Based Analysis of Varicella-Zoster Virus IgG and IgM Seropositivity in Korea, 2014–2024

Background: Varicella-zoster virus (VZV) remains an endemic, vaccine-preventable infection in Korea, despite high national vaccination coverage. Understanding long-term population immunity trends is essential for refining the disease-control and immunization policies. In this nat...

Postoperative Supraspinatus Muscle Volume Restoration Is Associated With Tendon Healing and Strength Recovery After Rotator Cuff Repair: Deep‐Learning‐Based Volumetric Analysis of the Entire Muscle With Clinical Correlation

Purpose To quantify supraspinatus muscle volume (SPV) change after rotator cuff repair using deep‐learning‐based segmentation of full‐coverage magnetic resonance imaging and evaluate its associations with clinical, radiologic parameters, and retears. Methods This retrospective st...

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...

Simplified, single-shot, capsule-preserving hydrodilatation combined with corticosteroids versus isolated corticosteroid injection for adhesive capsulitis: a randomized controlled trial

Glenohumeral corticosteroid injection has been a major treatment for adhesive capsulitis of the shoulder. Hydrodilatation is also a treatment option. However, few studies have considered the combined treatment of the two methods with heterogeneous protocols and results. The purpo...

Intraoperative Factors Associated With Postoperative Febrile Infectious Complications Following Retrograde Intrarenal Surgery: A Propensity Score-Matched Study

Purpose: To investigate the intraoperative factors associated with postoperative febrile infectious complications following retrograde intrarenal surgery (RIRS).Materials and Methods: A total of 352 patients who underwent RIRS for renal stones between March 2017 and December 2022...

Short-Term Cognitive and Behavioral Changes After Low-Intensity Transcranial Ultrasound Stimulation in Early Alzheimer’s Disease: An IPTW-Adjusted Retrospective Exploratory Comparative Study

Background: Low-intensity ultrasound (LIUS) has been proposed as a non-invasive approach to modulate cerebrospinal fluid movement, glymphatic–lymphatic clearance, and amyloid-beta (Aβ) handling in Alzheimer’s disease (AD). However, clinical comparisons in amyloid biomarker-confir...

Blood viscosity is associated with smoking status rather than the presence of chronic obstructive pulmonary disease: findings from the Korea COPD Subgroup Study (KOCOSS)

Abstract Background The relationship between smoking and blood viscosity is well established. However, the role of blood viscosity in the development of chronic obstructive pulmonary disease (COPD) and its impact on lung function decline remains unclear. Therefore, we aimed to in...
