Commissural Fiber Disruption Is Associated With Symptom Onset in Cerebral Autosomal-Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy.

Background: Extensive white matter hyperintensities are a hallmark of cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a monogenic small-vessel disease caused by pathogenic variants. This study aimed to assess microstructural white matter integrity in symptomatic and premanifest CADASIL individuals utilizing peak width of skeletonized mean diffusivity (PSMD), a diffusion tensor imaging-based metric.

Methods: A total of 161 participants were recruited, including 60 patients with symptomatic CADASIL, 67 preclinical variant carriers, and 34 healthy controls.

Protective Effects of Liriodendrin Against Oxidative Stress and Ferroptosis in a Mouse Model of Lipopolysaccharide-Induced Acute Respiratory Distress Syndrome.

Liriodendrin, a bioactive lignan diglucoside derived from several medicinal plants, has been demonstrated to exhibit pharmacological activities, such as antioxidative and anti-inflammatory activities. Up to now, no evidence has shown that acute respiratory distress syndrome (ARDS) is improved by liriodendrin. This study was conducted to investigate the protective effects of liriodendrin against oxidative stress and ferroptosis, key mechanisms underlying the pathogenesis of ARDS, in a mouse model of lipopolysaccharide (LPS)-induced ARDS.

Comorbidity with fibromyalgia predicted poorer outcomes in patients with chronic migraine on flunarizine: Prospective proof-of-concept study.

AimFibromyalgia (FM) and chronic migraine (CM) are commonly comorbid. Clinical observations suggest patients with chronic migraine comorbid with fibromyalgia (CMFM) seem less responsive to migraine preventive treatment; however, evidence is still lacking. This study examined the responsiveness to migraine preventive treatment in patients with CM and CMFM.

Regional Differences in Presentation, Cause, and Outcome of Reversible Cerebral Vasoconstriction Syndrome.

Background: National studies on reversible cerebral vasoconstriction syndrome (RCVS) point to differences between Asian and European patients. We investigated geographic variations in neurological complications, outcomes, and causes.

Methods: We conducted an exploratory analysis of pooled individual patient data from the Reversible Cerebral Vasoconstriction Syndrome International Collaborative network, a multicenter observational cohort study including patients with definite RCVS from 2 French, 32 Italian, 1 South Korean, and 1 Taiwanese centers.

Cross-Ancestry Associations of Spontaneous Coronary Artery Dissection Genetic Risk With Coronary Atherosclerosis and Migraine Headache.

Background: Research studies of spontaneous coronary artery dissection (SCAD) have been primarily focused on European-ancestry individuals, with limited recognition and investigation in non-European-ancestry individuals. While SCAD has not been well ascertained in non-European-ancestry groups, pleiotropic associated traits identified in those of European ancestry have been assessed in individuals of other ancestries. Whether these traits are associated with the complex genetic architecture of SCAD in those of non-European ancestry has not been previously investigated.

Activation of central and peripheral transient receptor potential melastatin 8 increases susceptibility to spreading depolarization and facilitates trigeminal neuroinflammation.

Background: Transient receptor potential melastatin 8 (TRPM8), a gene encoding a nonselective cation channel responsive to cold stimuli, has been implicated in migraine susceptibility. Despite this association, the role of TRPM8 to migraine pathogenesis remains elusive. This study aims to elucidate the potential role of TRPM8 in migraine pathophysiology.

The impact of COPD-bronchiectasis association on clinical outcomes: insights from East Asian cohorts validating the ROSE criteria.

Background: The radiology, obstruction, symptoms and exposure (ROSE) criteria provide a standardised approach for identifying the "COPD-bronchiectasis (BE) association." However, the clinical implications and outcomes of the COPD-BE association in East Asian populations remain unclear. Our study applied the ROSE criteria to assess the prevalence, clinical impact and outcomes of the COPD-BE association in an East Asian cohort, and compared that cohort with nonsmoking BE patients with fixed airflow obstruction (FAO) and those without FAO.

Towards a holistic framework for multimodal LLM in 3D brain CT radiology report generation.

Multi-modal large language models (MLLMs) have transformed the landscape of modern healthcare, with automated radiology report generation (RRG) emerging as a cutting-edge application. While 2D MLLM-based RRG has been well established, its utility for 3D medical images remains largely unexplored. In this regard, we curate the 3D-BrainCT dataset (18,885 text-scan pairs) and develop BrainGPT, a clinically visual instruction-tuned (CVIT) model designed for 3D CT RRG.

Kirenol ameliorates endotoxin-induced acute lung injury by inhibiting the ERK and JNK phosphorylation-mediated NFκB pathway in mice.

Acute lung injury (ALI) is a pathological condition characterised by varying degrees of lung damage in patients. Kirenol exerts anti-inflammatory, immunosuppressive, and antioxidative effects. We investigated the protective effects of kirenol on lipopolysaccharide-induced ALI in mice.
