Eliminating Texture‐Induced Retention of Self‐Assembled Monolayer Residues for High‐Performance Perovskite Solar Cells

Self-assembled monolayers (SAMs) constitute foundational interfacial elements in high-efficiency inverted perovskite solar cells (PSCs); however, ensuring chemical and electronic integrity across SAM-modified interfaces remains challenging. Although post-deposition solvent washin...

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...

Trastuzumab plus nivolumab with gemcitabine and cisplatin as first-line therapy for HER2-positive unresectable biliary tract cancer: a phase 1b/2 trial

Biliary tract cancers (BTCs) are associated with poor outcomes despite recent incorporation of immune checkpoint inhibitors into first-line chemotherapy. Human epidermal growth factor receptor 2 (HER2) overexpression or amplification defines a therapeutically targetable subset of...

Comparison of Uncovered and Covered Biliary SEMS for the Salvage of Obstructed SEMS: A Multicenter Retrospective Propensity Score–Weighted Study

BACKGROUND AND AIMS: Recurrent biliary obstruction (RBO) is common after uncovered self-expandable metal stent (UCSEMS) placement in unresectable distal malignant biliary obstruction. We compared stent patency, clinical outcomes, and RBO patterns between fully covered (FCSEMSs) a...

Ultrahigh Detectivity Colloidal Quantum dot Avalanche Photodetectors Driven by Electron Mobility of the n‐Type Layer

ABSTRACT Colloidal quantum dots (CQDs) are pragmatic candidates for infrared photodetectors due to their high absorption coefficient in the infrared region and solution processability. In addition, an incorporation of avalanche multiplication within the CQD region offers a route...

Cumulative Local and Metachronous Recurrence Rates in Patients with Ulcerative Colitis-Associated Neoplasia after Endoscopic Submucosal Dissection

Background/Aims: Endoscopic submucosal dissection (ESD) has emerged as a curative alternative for ulcerative colitis-associated neoplasia (UCAN), particularly when endoscopic mucosal resection is not feasible for complete resection. This study aimed to evaluate cumulative inciden...

Ociperlimab and tislelizumab in advanced esophageal squamous cell carcinoma (AdvanTIG-203): a phase II study

Patients with esophageal squamous cell carcinoma (ESCC) have an unmet need for new therapies that improve survival. In this phase II trial, patients received ociperlimab and tislelizumab (A) or placebo and tislelizumab (B) (NCT04732494). The primary endpoint was objective respons...

Arthroscopic partial meniscectomy should be performed carefully for medial meniscus tear with the anteromedial meniscofemoral ligament

The clinical relevance of the anteromedial meniscofemoral ligament (AMMFL) in medial meniscus (MM) tears remains unclear. This study investigated whether arthroscopic partial meniscectomy (APM) for MM tears with AMMFL is associated with joint degeneration. Among 2568 patients who...

High rates of transition to immune active disease in a cohort of strictly defined immune tolerant patients with chronic hepatitis B: results from the RADICAL consortium

Background Patients with immune tolerant (IT) chronic hepatitis B (CHB) have high viral loads, minimal inflammation and minimal fibrosis. Nevertheless, the benign nature of this phase and the need for antiviral therapy remain controversial. Objective We explored the natural histo...

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...

Chronic Subdural Hematoma in the Super-Aged Society: From a Traumatic Curiosity to a Self-Perpetuating Vascular-Inflammatory Disease

Chronic subdural hematoma (cSDH) was traditionally regarded as a simple mechanical consequence of head trauma, treated by burr-hole drainage alone. Recent ultrastructural, histopathological, and clinical evidence has reframed cSDH as a chronic, self-perpetuating disease driven by...

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...

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...

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...

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...

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...

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...

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...
