Comparison of vascular access outcomes in octogenarian patients undergoing hemodialysis

Background: The number of patients aged ⩾80 years with end-stage kidney disease is increasing, making vascular access selection increasingly challenging. Although arteriovenous fistula (AVF) is generally preferred, its advantages over arteriovenous graft (AVG) in very elderly pat...

Establishment of Sex- and Age-Specific Pediatric Alkaline Phosphatase Reference Intervals by Indirect Methods

Background: Establishing pediatric reference intervals using the direct method is often limited by the challenges of specimen collection and associated costs.As an alternative, the indirect method enables reference interval estimation without the need for additional specimen coll...

Standards for practical management of drug hypersensitivity reactions to intravenous drugs and proactive early allergy involvement before referral: A WAO Statement

Hypersensitivity reactions to intravenous therapies—including antibiotics, chemotherapeutics, biologics, anesthesia agents, and contrast media—pose significant challenges in acute care settings. These reactions often occur outside the purview of allergy specialists, leading to de...

Dual Effects of β‐TrCP2 Deletion in Bone Homeostasis: Suppression of Osteoclastogenesis and Enhancement of Osteoblast Activity

OBJECTIVES: To elucidate role of beta-transducin repeat-containing protein 2 (β-TrCP2) in bone homeostasis for its potential as a therapeutic target for osteoporosis. METHODS: ) mice. Bone microarchitecture was assessed by micro-computed tomography, and osteoclast and osteoblast...

Clinical Outcomes of Single Intramedullary K-Wire Fixation with Figure-of-Eight Suture Augmentation for Ulnar Styloid Base and Distal Ulnar Metaphyseal Fractures

Background/Objectives: The optimal fixation method for ulnar styloid base fractures remains controversial. Conventional dual K-wire fixation may be technically challenging in certain fracture configurations, whereas hook plate fixation provides rigid fixation but requires additio...

Intrinsic chain-end stabilization enables chain-transfer-agent-free living cationic ring-opening polymerization of cyclic enol ethers

Cationic ring-opening polymerization of substituted six-membered cyclic enol ethers offers a distinct route to vinyl polymers with head-to-head alternating side chains. However, poor control over the propagating chain-end—conventionally assumed to be a ring-opened oxocarbenium io...

Self-perceptions of aging in Korean older adults: a latent profile analysis

Abstract Background Self-perceptions of aging (SPA) are multidimensional and have been consistently associated with mental health and quality of life in later life. However, most prior research has relied on variable-centered approaches that treat SPA as a single positive-negativ...

Missed Opportunities for Stroke Prevention in Patients With Hypertension: A Retrospective Case–Control Study

BACKGROUND: Hypertension is the leading modifiable risk factor for ischemic stroke, yet the adequacy of preventative hypertension care in routine clinical practice remains suboptimal, potentially representing missed opportunities for stroke prevention. We evaluated the associatio...

Transdiaphragmatic pericardial window approach for blunt suprahepatic inferior vena cava injury: a case report

Suprahepatic inferior vena cava (SHIVC) injuries from blunt trauma are exceptionally rare and nearly uniformly fatal, with reported mortality rates ranging from 70% to 90%. Traditional approaches require cardiopulmonary bypass or extensive thoracotomy, often unavailable in emerge...

Prevalence and Lack of Cross-Sectional Association Between Positive Lactulose Breath Test Findings and Fecal Calprotectin Positivity in Patients with Functional Diarrhea

Background/Objectives: Functional diarrhea (FDr) is a common gastrointestinal disorder, and alterations in the gut microbiota have been proposed as one of its potential pathophysiological mechanisms. Hydrogen/methane breath tests are commonly used to identify findings suggestive...

Synthetic data-driven framework for estimating worker activity intensity using pose-based graph neural networks

This paper proposes a metabolic equivalent of task (MET) class prediction framework that combines Stable Diffusion-generated synthetic images with B-ResSkelGCN, which learns from skeleton graphs, for non-contact evaluation of construction workers' workload levels. Using domain-in...

Trajectories of health-related quality of life and associated factors after percutaneous coronary intervention

Coronary artery disease (CAD) is a leading cause of morbidity worldwide. The first six months after percutaneous coronary intervention (PCI) are a recovery period during which health-related quality of life (HRQoL) varies substantially across patients. We examined latent trajecto...

Conditional Inclusion and State‐Mediated Structural Injustice in Korea's Migration Regime

ABSTRACT This study examines how conditional inclusion operates through state‐mediated structural injustice in Korea's migration regime. Drawing on the concept of the conditionality structure of immigrant rights—encompassing both institutional and operational dimensions—the study...

Indoor radon exposure and ventilation-driven mitigation in a high-rise residential unit using source-term-informed monitored-zone assessment

Increasing airtightness in high-rise residential buildings can enhance indoor radon accumulation when persistent indoor source terms are combined with limited air exchange. This study evaluated indoor radon accumulation and ventilation-driven reduction in four monitored zones of...

Long-term exposure to ambient air pollution and an increased risk of hyperuricemia

Abstract Objectives Evidence suggests that ambient air pollution contributes to metabolic dysregulation, including hyperuricemia. However, previous studies were limited to specific groups or regions with relatively high air pollutant concentrations. This study examined the associ...

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...

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...

Utilisation and barriers to health check-ups among people living with human immunodeficiency virus in South Korea: a cross-sectional survey of clinic-attending patients

People living with human immunodeficiency virus (PLWH) continue to experience higher mortality rates than that in the general population. As this increased mortality is largely attributed to chronic comorbidities, regular health check-ups are required. This cross-sectional survey...

Estimation of System Parameters Including Repeated Cross-Sectional Data through Emulator-Informed Deep Generative Model

Abstract. Differential equations (DEs) are widely used to model the evolution of natural or engineered systems. Traditionally, the parameters in DEs are adjusted to fit data obtained through system observations. However, in fields such as politics, economics, and biology, the obs...

Identifying Systematic Origin–Destination-Level Mismatches Between Household Travel Surveys and Mobile Phone Data: A Case Study of Seoul

This study examines mismatches between Household Travel Survey (HTS) and mobile phone-based LTE/5G Cellular Signaling (LCS) data in representing origin–destination (OD) trip patterns in Seoul, South Korea. By comparing OD flows across subgroups defined by travel type, age group,...
