Admission-time prediction of 7-day mortality in clinician-attributed hypertensive intracerebral hemorrhage: development and external validation against the ICH score

Early mortality after intracerebral haemorrhage remains difficult to estimate at admission. We developed models for recorded mortality within 7 days after admission in two retrospective cohorts of clinician-attributed hypertensive intracerebral haemorrhage. Qingyuan records ( n =...

Joint trajectories and associated characteristics of postpartum depressive and anxiety symptoms: a longitudinal study

Postpartum depressive and anxiety symptoms are common postpartum mental health issues, and these symptoms often co-occur. However, previous studies have primarily analyzed them separately, with limited evidence regarding their joint developmental trajectories and associated chara...

Association between eye movement behavioral indicators and plasma p-tau217

Alzheimer’s disease (AD) represents a growing global public health burden driven by progressive population aging. Early identification of AD-related pathological alterations is essential for timely intervention and risk stratification; however, currently available screening appro...

An integrated immune-related signature reveals prognostic and immune–microbiome–genomic interactions in head and neck squamous cell carcinoma

Background Head and neck squamous cell carcinoma (HNSCC) is characterized by substantial biological diversity and heterogeneous clinical outcomes. Immune-based therapies have improved treatment options for some patients; however, reliable biomarkers capable of accurately defining...

Efficacy of early blood purification on serum inflammatory mediators in severe acute pancreatitis: a systematic review and meta-analysis

Severe acute pancreatitis (SAP) is the most critical form of acute pancreatitis (AP), characterized by a dysregulated systemic inflammatory response that drives early organ failure and mortality. Current management remains mainly supportive. Early blood purification (EBP) has bee...

Obstructive sleep apnea as a risk factor for postoperative complications in lumbar spine surgery: a nationwide inpatient sample database study

Obstructive sleep apnea (OSA) is a prevalent sleep-disordered breathing condition associated with systemic comorbidities; however, its specific impact on postoperative outcomes following lumbar spine surgery (LSS) remains under-characterized. This study aimed to determine the evo...

Motivation, engagement, and perceived competence gains in competition-based medical education: a theory-informed structural equation modeling study

Competition-based learning is increasingly used in medical education to promote active participation, innovation, and collaborative problem solving. However, less is known about how students’ participation motivation, engagement, perceived competence gains, and satisfaction are r...

Optimization Method for Area Controller Scheduling Integrating Efficiency, Fatigue and Fairness

Abstract To address the problem that existing scheduling methods for area air traffic controllers cannot effectively coordinate and optimize operational efficiency, fatigue risk, and working time fairness, this paper proposes a collaborative optimization method based on the multi...

EFAU-Net: efficient feature-enhanced U-Net for early pregnancy ultrasound segmentation

Early-pregnancy ultrasound images often contain gestational sac, yolk sac, and embryo regions with blurred boundaries, variable shapes, and small target sizes, which makes accurate segmentation difficult. In addition, many existing segmentation networks have high computational co...

Quantifying authenticity in historic districts: an integrated framework of morphological indicators and social perception based on Scenes Theory

Tourism commercialization poses growing challenges to the preservation of authenticity in historic districts. Current conservation practices often focus on physical spaces, yet may overlook the integrity of “Scenes” as an integration of material and intangible elements, potential...

Epidemiology of food allergy in children under 3 years old in Guangdong: a community cross-sectional study

This study aimed to investigate the prevalence, major allergens, and associated risk factors of food allergy (FA) among children under three years old in Guangdong, China. A community-based cross-sectional study was conducted in 2023 across three cities (Guangzhou, Foshan, Huizho...

Symbolic or Substantive? The Impact of Managerial Climate Awareness on Firms' Sustainability

ABSTRACT This study examines whether managerial climate awareness contributes to symbolic or substantive sustainability of Chinese publicly listed firms. We find that only when managers' climate awareness is high enough will they significantly drive firms toward substantive susta...

Recent Advances in the Functionalization Design and Applications of Natural Polyphenols in Metal–Organic Frameworks

As naturally occurring bioactive molecules derived from plants, polyphenols exhibit significant potential for the functional modification and structural regulation of metal–organic frameworks (MOFs) due to their unique ortho-phenolic hydroxyl groups, excellent metal-coordinating...

Cardiac MR Characterization of Infarct‐Related and Remote Myocardial Injury in Multivessel Disease After Acute Myocardial Infarction

BACKGROUND: Patients with multivessel disease (MVD) after acute myocardial infarction (AMI) have worse outcomes than those with single-vessel disease (SVD), but whether MVD is associated with diffuse myocardial injury beyond the infarct zone (IZ) remains unclear. PURPOSE: To char...
