Machine Learning-Based First-Trimester Antenatal Risk Prediction for Adverse Maternal and Neonatal Outcomes: Multicenter Model Development Study.

Background: Maternal outcomes remain inequitable worldwide. Severe morbidity persists, and current risk assessment tools are largely arbitrary, focusing on biomedical factors while overlooking social determinants of health. There is a need for data-driven AI models to improve ear...

Data-driven risk algorithms from primary care for early dementia detection and prevention trial enrichment

Background: Early identification of individuals at risk of dementia is essential for effective prevention and timely intervention. Existing risk scores rely heavily on age, which limits their discriminative power at clinically relevant thresholds such as 65 years, when preventive...

Effect of chocolate preference and cocoa content on experimentally induced muscle pain

Abstract Objectives Chocolate consumption has been associated with pain reduction, but it remains unclear whether this effect depends on cocoa concentration or individual preference. This study aimed to investigate whether chocolate preference and/or cocoa content modulate experi...

Effects of mandibular advancement device versus continuous positive airway pressure on cardiac remodeling in obstructive sleep apnea: a randomized CMR substudy

Obstructive sleep apnea (OSA) is associated with adverse cardiac remodeling, including diffuse myocardial fibrosis. Continuous positive airway pressure (CPAP) is the standard treatment for OSA, while mandibular advancement devices (MAD) may represent an alternative. However, thei...

Cohesin acts as a transcriptional gatekeeper by restraining pause–release to promote processive elongation

Abstract Cohesin organizes 3D chromatin architecture, including promoter–enhancer loops, yet its loss has surprisingly modest effects on steady-state gene expression. We address this paradox by demonstrating that cohesin acts at different stages of transcription. First, it promot...

Viral dissemination and diagnostic insights from experimental infection of sheep with Crimean-Congo hemorrhagic fever virus

Abstract Crimean-Congo hemorrhagic fever virus (CCHFV) is a tick-borne orthonairovirus widely distributed across Asia, Africa, the Middle East, and Southern Europe, causing severe illness and hemorrhagic fever in humans. While sheep usually show no clinical symptoms, they develop...

Association of blood-pressure time-in-therapeutic range with morbidity and mortality in hypertensive patients: a retrospective cohort study in the community setting

Abstract Background Hypertension is one of the leading modifiable risk factors for cardiovascular disease. This study assessed the association between good blood pressure control (GBPC), measured by time in therapeutic range (TTR) during the first year after hypertension diagnosi...

Hormonal Responses to a Short Daytime Fast in Children With Beta‐Oxidation Disorders

ABSTRACT Fasting‐induced cellular energy deficiency and hypoglycemia are well‐known complications of beta‐oxidation disorders. The changes in energy homeostasis during fasting are under hormonal regulation. This aspect of fasting metabolism in beta‐oxidation disorders is not full...

Familial Co‐Aggregation of Neurodevelopmental Conditions and Childhood‐Onset Type 1 Diabetes

ABSTRACT Aim Childhood‐onset Type 1 diabetes (T1D) is associated with neurodevelopmental conditions (NDCs). We examined whether this association extends to relatives and assessed phenotypic, genetic, and environmental correlations between T1D and NDCs. Methods Using Swedish regis...

Internet-based Emotion Regulation Individual Therapy for Adolescents (IERITA) plus treatment as usual versus treatment as usual for adolescent outpatients with non-suicidal self-injury—the TEENS multi-site trial: study protocol and statistical analysis plan for a multi-site randomised clinical trial

Non-suicidal self-injury (NSSI) is a public health concern and a widespread behaviour, especially among adolescents. NSSI is an indicator of psychological distress and a known risk factor for later suicidal behaviour and death by suicide; however, evidence-based treatment options...

P1.123. Deep Learning and Machine Learning Radiomics-Based Models Predicting Esophagogastric Cancer Recurrence: A Systematic Review

Abstract Topic Esophageal Cancer: Oncology/Radiation Therapy Background Esophageal and gastric cancers are associated with recurrence rates approaching 50% despite curative-intent treatment. Non-invasive imaging modalities including computed tomography (CT), positron emission tom...

P1.004. Cryoablation of Barrett´s Esophagus in Patients not Suitable for Treatment With Radiofrequency Ablation

Abstract Topic Benign Disease: Barrett’s Esophagus: Pathology and Pathophysiology; Non-invasive Neoplasia Background Radiofrequency ablation (RFA) is the gold standard for ablation of the esophagus. However, there are occasions when RFA is not suitable, for example if the patient...

P1.005. Preliminary Pilot Study Cohort Results - Cost-Effective Surveillance Strategies and Prediction of Cancer Recurrence After Endoscopic Therapy for Barrett’s Esophagus (Endeavor)

Abstract Topic Esophageal Cancer: Barrett‘s Esophagus: High-Grade Dysplasia and Early Invasive Cancer Background In many European countries, esophageal adenocarcinoma (EAC) incidence is increasing [1]. Barrett’s esophagus(BE), strongly associated with EAC, can progress via dyspla...

OA03-RF01.05. The Safety and Efficacy of Endoscopic Submucosal Dissection for Early Esophageal Squamous Cell Carcinoma in Scandinavia (SEES-Study)

Abstract Topic Esophageal Cancer: Surgical Treatment of Esophageal Cancer – early outcomes and complications Background Endoscopic submucosal dissection (ESD) is recommended for early-stage esophageal squamous cell carcinoma (ESCC). Most data on the efficacy of ESD for ESCC comes...

Are sleep and breakfast behaviours predictors of active or independent commuting to school in Spanish youth?

Abstract Background Despite increasing interest in the association between active commuting to school (ACS) and health-related behaviors, the existing literature presents inconsistent findings regarding the relationships between ACS and preceding behaviors such as sleep duration...

Accelerating protein design by scaling experimental characterization

Abstract Recent advances in de novo protein design have greatly outpaced standard protein biochemistry workflows, and experimental testing has been a bottleneck in the validation of new designs and methodologies. Here, we describe experimental and computational workflows to addre...

Modulation of neuronal excitability and plasticity by BHLHE41 conveys lithium non-responsiveness

Abstract Many bipolar disorder (BD) patients are non-responsive to lithium. The mechanisms underlying lithium (non-)responsiveness are largely unknown. By using gene-set enrichment analysis methods, we found that core clock gene-sets are significantly associated with lithium resp...

High-Ratio Partial Proteolysis with Carrier Proteome (HOLSER) Enables Global Structure Profiling and Site-Resolved Elucidation of Ligand-Protein Interactions.

Understanding how cellular proteins interact with their environment, including endogenous and exogenous molecules, is critical for elucidating mechanisms of cellular regulation and drug action. Partial proteolysis-based techniques offer peptide-level resolution of ligand-induced...

Association of pre-clinical depressive symptoms and its plasma metabolomic signature with Parkinson’s disease: a community-based longitudinal study

Abstract Accumulating evidence has suggested that depression is associated with an increased risk of Parkinson’s disease (PD), yet whether pre-clinical depressive symptoms in PD development and the potential mediating effects of metabolomic profiles remain unclear. We aimed to ex...

Clinical outcomes and opportunities for improvement across modified trauma quality improvement cohorts: a registry-based cohort study

<title>Abstract</title> Background The American College of Surgeons Trauma Quality Improvement Program (TQIP) relies primarily on risk-adjusted mortality benchmarking, yet mortality alone may overlook non-fatal morbidity and care-process failures, particularly in cohorts where ou...
