Demand-Sensitive Time Allocation in Digital Reading: Evidence from 25 Education Systems

Digital assessments record item-visit durations and revisiting. These traces can reveal responses to task difficulty, but achievement associations do not establish stable person-level measures. We linked digitalPIRLS 2021 process, response, and achievement data across 25 educatio...

Serial ultrasonographic monitoring during defibrotide treatment of sinusoidal obstruction syndrome after hematopoietic stem cell transplantation: a longitudinal study of treatment response

Purpose: This study evaluated serial ultrasonographic (US) changes during defibrotide therapy for sinusoidal obstruction syndrome (SOS) after hematopoietic stem cell transplantation, identifying parameters whose temporal trajectories differed by treatment response.Methods: This r...

Multiplexed intravascular molecular imaging using dual-channel near-infrared fluorescence integrated with optical coherence tomography

Abstract Accurate characterization of high-risk atherosclerotic plaques requires both structural and molecular information. While integrated optical coherence tomography (OCT)/near-infrared fluorescence (NIRF) imaging enables simultaneous assessment of plaque morphology and biolo...

Bicycle-Related Acetabular Fractures Are Associated with Anterior Column Involvement: A Multicenter Study with an Exploratory Analysis of Clipless Pedal Use

Background/Objectives: Cycling-related acetabular fractures have not been well described. We aimed to determine the proportion of acetabular fractures associated with bicycle accidents and to compare their fracture patterns with those caused by other mechanisms. Findings related...

Deep learning-based profanity detection in social media: a survey in the context of toxic language detection

The spread of toxic and profane language across online platforms has necessitated the development of advanced automated detection systems to maintain safe online environments. This survey comprehensively explores the progression of profanity language detection techniques, focusin...

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...

Beyond Mean Score Differences: Home Language and the Interpretation of Cognitive Test Performance in China

Large-scale surveys often use cognitive test total scores to describe group differences, but the construct meaning of such scores depends on task content, administration, language experience, and opportunities to learn. The China Family Panel Studies (CFPS) word test is an oral M...

Achievement goal theory in AI-supported learning: Psychological pathways and configurations leading to student engagement

Artificial intelligence (AI) is increasingly integrated into higher education, yet little is known about how students’ achievement goal orientations are associated with their engagement in AI-supported learning. Grounded in Achievement Goal Theory, this study examined the relatio...

Phase IIa Trial of Locoregional High-Dose Autologous Natural Killer Cell Therapy Combined with Hepatic Arterial Infusion Chemotherapy for Locally Advanced Hepatocellular Carcinoma

PurposeHepatocellular carcinoma (HCC) refractory to locoregional therapies remains a major clinical challenge.This study evaluated the efficacy and safety of locoregional high-dose autologous natural killer (NK) cell therapy combined with hepatic arterial infusion chemotherapy (H...

Transgluteal Decompression of the Pudendal Nerve in Pudendal Neuralgia: Implications of Sacrospinous Ligament Resection

Objective: This study evaluated the efficacy of pudendal nerve decompression via the transgluteal approach for pudendal neuralgia and examined factors associated with surgical outcomes.Methods: Pain reduction was analyzed in 14 patients with pudendal neuralgia who underwent trans...

Radiofrequency Ablation for Papillary Thyroid Carcinoma versus Surgery and Other Thermal Ablation Techniques: A Systematic Review and Meta-Analysis of Outcomes

Background: Radiofrequency ablation (RFA) has been proposed for selected patients with low-risk papillary thyroid carcinoma (PTC). This study compared the effectiveness, safety, and procedural characteristics of RFA with those of surgery and other thermal ablation techniques. Met...

Pathological calcium overload impairs skeletal muscle regeneration through sustained NFAT-dependent proliferative signaling

Abstract Skeletal muscle regeneration requires coordinated myoblast proliferation and differentiation. Calcium dysregulation is commonly observed in aging and disease-associated muscle weakness; however, its impact on myogenic progression remains unclear. In this study, we invest...

Interplay Between the Gut Microbiome and Oxidative Stress in Type 2 Diabetes

Type 2 diabetes (T2D) develops when pancreatic beta cells progressively fail to compensate for insulin resistance in a host environment shaped by diet, adiposity, aging, medications, and genetics. Gut microbial dysbiosis and oxidative stress are often treated as parallel abnormal...

Timing of Full Enteral Feeding and Longitudinal Gut Microbiome Development in Infants Admitted to the Neonatal Intensive Care Unit

Background/Objectives: Delayed achievement of full enteral feeding (FEF) is common in neonatal intensive care unit (NICU) infants but is closely linked to gestational age (GA). We examined whether time to FEF is associated with gut microbiome development from birth to 6 months of...

2025 Korean Guidelines for Cardiopulmonary Resuscitation: Part 7. Pediatric basic life support: a secondary publication

Pediatric cardiac arrest primarily arises from asphyxia in infants and trauma in older children, contrasting with adult etiologies dominated by cardiac events. This underscores prevention as the cornerstone of pediatric basic life support, through injury mitigation like child res...

2025 Korean Guidelines for Cardiopulmonary Resuscitation: Part 8. Pediatric advanced life support: a secondary publication

The 2025 Korean pediatric advanced life support guideline update introduces clinically important revisions emphasizing airway strategy, physiologic resuscitation targets, post-cardiac arrest hemodynamics, neuroprotection, and extracorporeal support. In out-of-hospital pediatric c...

2025 Korean Guidelines for Cardiopulmonary Resuscitation: Part 9. Neonatal resuscitation: a secondary publication

The 2025 Korean Guidelines for Cardiopulmonary Resuscitation provide updated, evidence-based recommendations to optimize the transition from intrauterine to extrauterine life. While approximately 85% of term newborns initiate spontaneous breathing independently, timely interventi...

Stereotactic body radiation therapy for hepatocellular carcinoma: 2026 expert consensus-based practical recommendation of the Korean Liver Cancer Association

Stereotactic body radiation therapy (SBRT) is a noninvasive, high-precision radiation technique that delivers a high dose to the tumor in a limited number of fractions, typically five or fewer, and is increasingly used as a curative-intent option for hepatocellular carcinoma (HCC...

Effects of Interpersonal Traumatic Experiences and Interpersonal Problems on Psychological Symptoms among College Students: Moderated Mediating Effect of Expressive Flexibility
