Income Dynamics and Incident Esophageal Cancer: A Retrospective Cohort Study

BACKGROUND: Although socioeconomic status is a recognized risk factor for esophageal cancer (EC), most studies have examined socioeconomic status at a single time point. We investigated the association between income dynamics and incident EC. METHODS: We analyzed 3,361,091 Korean...

TapBR-SSM: High-Resolution Segmentation and Longitudinal Ellipse-Normalized Contour Analysis of an On-Load Tap-Changer Component

An on-load tap changer (OLTC) regulates transformer voltage under load, while repeated portable imaging provides records of accessible component geometry. This study proposes TapBR-SSM, which combines high-resolution HRNet features, stage-selective Mamba-inspired directional refi...

Early Discontinuation of Opioid-Based Intravenous Patient-Controlled Analgesia After Single-Port Adnexal Laparoscopy: Incidence, Reasons, and Postoperative Outcomes

Background/Objectives: Opioid-based intravenous patient-controlled analgesia (IV-PCA) provides postoperative analgesia but can cause adverse effects that lead to early discontinuation. In relatively limited procedures such as single-port access (SPA) adnexal laparoscopy, the bala...

Artificial intelligence-based thigh muscle volume profiling on CT in elderly East Asian patients with hip fracture

Background Skeletal muscle mass and quality are critical determinants of outcomes in hip fracture patients. However, most prior studies have relied on 2D cross-sectional area measurements, which may not accurately reflect the complex 3D muscle distribution. This study aimed to qu...

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...

Fasting Duration and Differences Across Routine Laboratory Tests

Importance Fasting before blood collection is widely practiced to reduce preanalytical variability, yet whether fasting-related differences are clinically meaningful across a broad panel of routine analytes has not been systematically evaluated using clinical data. Objective To e...

Staged and Simultaneous Bilateral Hip Arthroscopy for Femoroacetabular Impingement Syndrome Achieves Clinical Outcomes Comparable With Unilateral Surgery at a Minimum 2‐Year Follow‐Up: A Systematic Review

Purpose To synthesize the available evidence comparing patient‐reported outcomes and reoperation rates between bilateral and unilateral hip arthroscopy in patients with femoroacetabular impingement syndrome, irrespective of whether bilateral procedures were performed in a staged...

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...

Vascular Imaging Features and Time-Specific Recurrence Risk After Craniocervical Artery Dissection

Background and ObjectivesCraniocervical artery dissection (CCAD) is a major cause of stroke in young adults, yet its recurrence risk remains poorly defined because of delayed enrollment in prior research. We aimed to determine the temporal distribution of recurrent ischemic strok...

Parental Competencies as Familial Protective Factors in Adolescent Substance Use Prevention: A Scoping Review

Parents play an important role in adolescent substance use prevention, yet the competencies underlying their protective role remain inconsistently conceptualized and measured. This scoping review aimed to map parental competencies as modifiable family-level protective factors for...

Feasibility Study of Deep Learning-Driven Image Restoration for Fast, Low-Count [18F]FP-CIT Digital PET/CT

Background/Objectives: N-3-[18F]fluoropropyl-2β-carbomethoxy-3β-4-iodophenyl nortropane ([18F]FP-CIT) positron emission tomography/computed tomography (PET/CT) is an effective imaging tool for diagnosing parkinsonism. This study evaluated the feasibility of deep learning (DL)-dri...

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...

Structural barriers to knowledge co-production in the context of public health crisis

Abstract Knowledge translation (KT) is widely recognized as essential for evidence-informed policymaking, yet the research-policy gap persists. Co-production, namely collaborative knowledge production among researchers, policymakers, and practitioners, has emerged as a promising...

Transverse carpal ligament thickness on wrist MRI in carpal tunnel syndrome: a retrospective case–control study

Abstract Carpal tunnel syndrome (CTS) is associated with structural alterations of the median nerve and surrounding components of the carpal tunnel; however, quantitative assessment of the transverse carpal ligament (TCL) remains limited. This exploratory retrospective case-contr...

Cross-cultural adaptation and validation of the Korean version of the Post-Intensive Care Syndrome Knowledge Test (K-PICS-KT): a methodological study

Purpose: This study aimed to develop the Korean version of the Post-Intensive Care Syndrome Knowledge Test (K-PICS-KT) through cross-cultural adaptation to ensure cultural and clinical appropriateness for use in Korea and to evaluate its validity and reliability.Methods: The Post...

Development of a customized three-dimensional bolus using transparent gel wax and its application in electron beam therapy

Abstract Purpose: This study aimed to develop a customized bolus using commercially available transparent gel wax (TGW) without requiring 3D printing technology and to evaluate its applicability in radiotherapy, including its physical and dosimetric characteristics. Methods: A de...

Residual urine volume and quality of life in maintenance hemodialysis

Abstract Background Residual urine volume in patients undergoing hemodialysis is closely linked to fluid balance and clinical outcomes. However, its association with quality of life (QOL), an important patient-centered outcome, has not been well characterized across a broad quant...

Dynamic change in body fat percentage and the risk of diabetes mellitus: a longitudinal analysis

Although higher body fat percentage (BF%) is associated with an increased risk of diabetes mellitus (DM), most evidence is derived from single time-point measurements. We aimed to investigate whether longitudinal changes in BF% are associated with incident DM. We analyzed 11,016...
