Background And Aims: Studies have recently revealed the linoleic acid metabolic pathway of Lactobacillus plantarum, the representative gut bacterium in human gastrointestinal tract, and the anti-inflammatory effects of metabolites in this pathway. However, no clinical trials have evaluated the association between these metabolites and revascularization in patients who underwent percutaneous coronary intervention (PCI).
Methods: We retrospectively reviewed patients who underwent PCI with subsequent revascularization or coronary angiography (CAG) without revascularization. Patients with frozen blood samples at the index PCI and revascularization or follow-up CAG were enrolled.
Results: Among 701 consecutive patients who underwent PCI, we enrolled 53 patients who underwent subsequent revascularization and 161 patients who underwent follow-up CAG without revascularization. Patients who underwent revascularization showed significantly lower plasma 10-oxo-octadecanoic acid (KetoB) levels (720.5 [551.6-876.5] vs. 818.4 [641.1-1103.6 pg/mL]; p = 0.01) at index PCI. Multivariate logistic regression analysis revealed that decreased plasma KetoB levels at the index PCI were independently associated with subsequent revascularization after PCI (odds ratio; 0.90 per 100 pg/mL increase, 95% confidence interval; 0.82-0.98). Additionally, in vitro experiments showed that the addition of purified KetoB suppressed the mRNA levels of IL-6 and IL-1β in macrophages and IL-1β mRNA in neutrophils.
Conclusions: Plasma KetoB level at index PCI was independently associated with subsequent revascularization after PCI, and KetoB could act as an anti-inflammatory lipid mediator in macrophages and neutrophils. The assessment of gut microbiome-derived metabolites may help predict revascularization after PCI.

Purpose: To explored key angiographic markers associated with headache risk in patients with unruptured brain arteriovenous malformations (BAVMs).
Methods: This retrospective study included patients with unruptured, supratentorial BAVMs without prior interventions who underwent digital subtraction angiography between January 2011 and January 2024. The patients were stratified into headache and nonheadache groups on the basis of symptoms at initial presentation.

Rationale/objectives: Image-based vascular biomarkers may help expedite evaluation of chronic thromboembolic pulmonary hypertension (CTEPH), which remains difficult to diagnose despite available effective therapies. We sought to determine if vascular heterogeneity and central redistribution on chest CT differed between CTEPH, pulmonary arterial hypertension (PAH), and control groups.
Materials/methods: We retrospectively included 108 patients who underwent right heart catheterization and chest CT (2011-2018).

Background: Final infarct volume (FIV) is a strong predictor of stroke outcomes. Although smaller FIV are associated with better outcomes, many patients fail to achieve functional independence. We aimed to identify poor outcome predictors in patients with anterior large vessel occlusion stroke (LVOS) who underwent mechanical thrombectomy (MT) and had small FIV.

Background: Carotid artery stenosis prevalence increases with age, and carotid endarterectomy (CEA) is a possible treatment option. However, nonagenarians are at high risk of experiencing postoperative complications and are often not considered surgical candidates. We aimed to identify risk factors associated with postoperative myocardial infarction (MI), stroke, and death within 30 days for nonagenarians undergoing CEA and to analyze the predictive ability of modified frailty indices (mFI) in predicting adverse outcomes for this population.

Background: Differentiating ischemic myelopathies from inflammatory demyelinating diseases is challenging due to overlapping imaging and clinical manifestations. Needle electromyography (EMG) is highly sensitive to spinal anterior horn damage.
Objectives: This study investigates the diagnostic value of spontaneous EMG activity in distinguishing ischemic myelopathies from inflammatory demyelinating diseases.
