Association Between Lithium Use and Suicide‐Related Behaviors in Bipolar Disorder: A Multicenter Study

BACKGROUND: Lithium has long been associated with reduced suicide risk in bipolar disorder; however, evidence from real-world clinical populations remains susceptible to confounding, and the behavioral correlates related to this association are not well characterized. METHODS: In...

Genetic prioritization and multi-omic characterization of GNS-associated thromboinflammatory signatures in venous thromboembolism

Venous thromboembolism (VTE) remains a major cause of cardiovascular morbidity and mortality. Beyond dysregulated coagulation, accumulating evidence implicates immune and inflammatory pathways in thromboinflammatory susceptibility. However, the genetic determinants of VTE and the...

Tozorakimab to Prevent COPD Exacerbations

BACKGROUND: Many patients with chronic obstructive pulmonary disease (COPD) have exacerbations despite receiving standard-of-care inhaled maintenance therapy. Dysregulated interleukin-33 signaling is implicated in the pathogenesis of COPD. Tozorakimab is a monoclonal antibody tha...

HNRNPK Lactylation Amplifies Inflammation and Exacerbates Myocardial Ischemia/Reperfusion Injury by Regulating Jag2 Splicing

BACKGROUND: Myocardial ischemia/reperfusion injury triggers profound metabolic reprogramming and lactate accumulation. However, how this metabolic stress regulates inflammatory gene expression remains poorly understood. We hypothesized that lactylation, a lactate-derived posttran...

Dextran-Mediated Macromolecular Crowding Drives the Formation of Multiphase Complex Coacervates from Soy Glycinin and Gum Arabic

Abstract Macromolecular crowders pose great impact on coacervation but that on the protein–polysaccharide complex coacervation has yet been investigated. In this study, dextran (Dex) was used as a crowder to investigate its influence on the complex coacervation of soy glycinin (S...

Burden dynamics of pulmonary arterial hypertension in China and the G20 aggregate: a comparative analysis based on the global burden of disease study 2023

BACKGROUND: Pulmonary arterial hypertension (PAH) causes substantial premature mortality and disability. Updated evidence comparing long-term PAH burden in China with the Group of Twenty (G20) aggregate remains limited. We assessed changes from 1990 to 2023 and projected future t...

Predicting left-ventricular recovery and characterizing Cardiorenal risk after Transcatheter aortic valve replacement: A routine-data phenotyping and prediction-model study

Background Ejection fraction (LVEF) underpins risk stratification before transcatheter aortic valve replacement (TAVR), yet it does not indicate whether an impaired ventricle will recover once the stenosis is relieved, or what drives death in high-risk patients. We asked whether...

Mutations in EnvZ, KPC, and OmpK36 contribute to the evolution from ceftazidime-avibactam heteroresistance to stable resistance in carbapenem-resistant Klebsiella pneumoniae

Antibiotic heteroresistance, an unstable phenotype wherein a minority-resistant subpopulation coexists with a majority-susceptible population, can evolve to stable resistance following in vivo antibiotic exposure, thereby substantially increasing the risk of treatment failure. Ho...

Hybrid long-read sequencing reveals genomic homogeneity, blaZ copy-number variation, and phenotypic adaptation of the emerging Asian ST188 MSSA lineage from pediatric gut and vaginal colonization sites, Southern China

Staphylococcus aureus ( S. aureus ) ST188 has emerged as an important methicillin-susceptible clonal lineage in Asia and is frequently associated with human colonization and community-acquired infections. This study investigates ST188 isolates from aerobic vaginitis and pediatric...

Evaluative performance of triglyceride-glucose-frailty index versus surrogate insulin resistance indices for advanced cardiovascular-kidney-metabolic syndrome, cardiometabolic multimorbidity, and mortality: the role of estimated glomerular filtration rate

Cardiovascular-kidney-metabolic (CKM) syndrome and cardiometabolic multimorbidity (CMM) carry substantial mortality, yet whether a composite index integrating insulin resistance and frailty shows stronger associations with advanced CKM syndrome, CMM, and mortality than convention...

Comparison of non-contrast, non-radiation percutaneous mechanical thrombectomy and catheter-directed thrombolysis in pregnancy-associated iliofemoral deep vein thrombosis: a propensity-matched retrospective cohort study

Iliofemoral deep vein thrombosis (DVT) during pregnancy poses considerable risks to both the mother and the fetus, making it essential to provide prompt, effective, and safe treatment options. Although catheter-directed thrombolysis (CDT) and percutaneous mechanical thrombectomy...

Genomic and transcriptomic landscape of overweight Chinese breast cancer reveals NOTCH2 mutation–mediated endocrine resistance and therapeutic strategies

Abstract Background Obesity (OB) and overweight (OW) are common in patients with breast cancer and are associated with inferior outcomes, yet their impact on tumor molecular architecture remains incompletely understood. This study aimed to define the genomic and transcriptomic fe...

Longitudinal plasma phosphorylated tau217 classification and the association with Alzheimer's disease progression

Abstract INTRODUCTION Longitudinal diagnostic and prognostic validity of plasma phosphorylated tau217 (p‐tau217) in Alzheimer's disease (AD) remains uncertain. METHODS In this multi‐cohort study of 2117 individuals, we established baseline plasma p‐tau217 thresholds for amyloid‐β...

IFI27 and BAX are Essential for GSDME‐Mediated Myeloma Cell Pyroptosis

ABSTRACT Induction of pyroptosis is a novel strategy for multiple myeloma (MM) treatment, but the underlying mechanism remains elusive. In the analysis of the transcriptomic profile in pyroptotic MM cells, we find the interferon‐alpha inducible protein IFI27 is strikingly upregul...

CD9 + B Cells Induce T Follicular Helper Cell Apoptosis to Regulate Germinal Center Regression

ABSTRACT Adenoid hypertrophy (AH) is associated with excessive proliferation of germinal center B (GC‐B) cells, yet the mechanisms underlying GC regression and termination remain poorly understood. This study used single‐cell RNA sequencing (scRNA‐seq) to profile the cellular com...

Autophagic degradation of RAB8A promotes ferroptosis through dysregulation of TFRC-mediated iron uptake

Ferroptosis is an iron-dependent form of regulated cell death driven by lipid peroxidation; however, how selective autophagy regulates ferroptotic sensitivity remains incompletely understood. Here, we identify RAB8A as a selective autophagic substrate and negative regulator of fe...

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

ABSTRACT Intrauterine injury triggers a self‐reinforcing cycle of inflammation, oxidative stress, and fibrosis that culminates in intrauterine adhesions (IUA), severely impairing women's reproductive health. Current treatments, including hysteroscopic adhesiolysis combined with h...

Neonatal hypoxia promotes pulmonary hypertension by upregulating ALKBH5 expression

Postnatal hypoxia in high-altitude regions drives pulmonary developmental impairment in neonates, which may subsequently progress to pulmonary hypertension and right ventricular failure. N6-methyladenosine (m6A) RNA modification regulates mRNA fate and cellular responses to stres...

Results reporting and primary endpoint achievement in interventional therapeutic trials for pleural mesothelioma, 2005–2025: a cross-sectional analysis

Pleural mesothelioma (PM) is a rare and aggressive malignancy in which therapeutic progress depends on a limited clinical trial evidence base. Although trial registration has improved transparency, the extent to which registered trials generate publicly available and clinically i...

MOCR-DB: The Multi-Omics Causal Resource Database for Genetic Correlation, Causal Inference, and Functional Interpretation

Abstract Genome-wide association studies (GWAS) have revealed extensive polygenic signals and overlapping genetic architectures across human traits, creating a need for resources that connect trait-level genetic relationships with gene-level functional evidence. Here, we develope...
