Long-Term Outcomes According to a Device-Assisted Enteroscopy Strategy after Capsule Endoscopy in Patients with Small Bowel Bleeding: A Nationwide Population-Based Cohort Study

Background/Aims: Although the use of device-assisted enteroscopy (DAE) has increased, few large-scale studies have examined long-term outcomes focused on small bowel (SB) bleeding. We analyzed National Health Insurance Service data to evaluate the clinical utility of DAE in patie...

Routine Nutritional, Inflammatory, and Redox-Related Biomarker Abnormality Burden Is Associated with Lower 12-Week Physical Performance After Cholecystectomy in Rehabilitation Outpatients

Simple tools for characterizing functional vulnerability after cholecystectomy are lacking, particularly among patients referred for outpatient rehabilitation. We examined whether a cumulative count of routine nutritional, inflammatory, and redox-related biomarker abnormalities a...

Association of Estimated Arterial Stiffness with Collateral Status and Functional Outcome after Endovascular Thrombectomy: A Secondary Analysis of the OPTIMAL-BP Trial

PURPOSE: Estimated pulse wave velocity (ePWV) is a surrogate of arterial stiffness that may influence stroke outcomes and potentially affect collateral circulation. We examined the association of ePWV with collateral status and 3-month functional outcome after successful endovasc...

Design and verification of a FHIR R4-serializable known-truth testbed for technical and inferential assurance in small longitudinal trial simulations

Simulation can expose inferential failure because truth is known, but technical correctness of the surrounding research-data system is seldom audited separately from statistical reliability. We developed a serialization-bounded known-truth testbed with four assurance layers: reco...

Distinct clinical patterns of preterm infants vulnerable to intestinal injury identified by unsupervised clustering

BACKGROUND: Current necrotizing enterocolitis (NEC) diagnostic criteria fail to capture the full spectrum of intestinal injury. We aimed to identify diagnosis-independent clinical patterns of intestinal injury among vulnerable very low birth weight (VLBW) infants using unsupervis...

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...

A Higher Burden of Abnormal Antioxidant-, Nutritional-, and Inflammation-Related Biomarkers Is Associated with Shoulder-Hand Syndrome, Hand Edema, and Short-Term Upper-Limb Outcomes During Stroke Rehabilitation

Post-stroke shoulder-hand syndrome and hand edema can complicate inpatient rehabilitation and may reflect interactions between antioxidant, nutritional, inflammatory, and neuro-musculoskeletal factors. This single-center retrospective cohort study included 453 adults admitted for...

The bone turnover marker procollagen type I N-terminal propeptide is associated with 12-week neurogenic heterotopic ossification after traumatic brain injury

Neurogenic heterotopic ossification (NHO) after traumatic brain injury may involve osteogenic synthesis of a type I collagen-rich matrix. Procollagen type I N-terminal propeptide (P1NP) reflects type I collagen formation. This single-center retrospective cohort study examined whe...

Long-term outcomes of single-radius total knee arthroplasty in an Asian population: a comparison of cruciate-retaining and posterior-stabilized designs

Abstract Background Single-radius total knee arthroplasty (TKA) has demonstrated favorable clinical outcomes and survivorship; however, long-term comparative data between cruciate-retaining (CR) and posterior-stabilized (PS) designs within a single-radius system remain limited, p...

Nonparetic forearm fracture and early upper-limb manual function outcomes after stroke rehabilitation

Upper-limb recovery after stroke may be affected by conditions that restrict the use of the nonparetic limb during early rehabilitation. We evaluated whether nonparetic forearm fracture was associated with early manual function outcomes after inpatient stroke rehabilitation. This...

Plasma Metabolomes Identify Distinct Asthma Metabotypes: Findings From the COREA Cohort

BACKGROUND: Phenotype-based asthma classification has limitations that have motivated endotype-based approaches grounded in pathophysiology. However, existing biomarkers offer limited specificity and clinical accessibility. Plasma metabolomics, which reflects disease-specific met...
