We aimed to assess whether blood-based biomarkers of inflammation and endothelial dysfunction, such as interleukin 6 (IL-6), vascular cell adhesion molecule (VCAM-1), and tumor necrosis factor-alpha (TNF-α), are associated with cognitive function over time in a prospective cohort of first-ever ischemic stroke patients. Data were obtained from the Prospective Cohort with Incident Stroke Berlin (NCT01363856). Cognitive function was assessed with the Telephone Interview for Cognitive Status-modified (TICS-m) at 1 to 3 years of follow-up. Associations of baseline levels of IL-6, VCAM-1, and TNF-α with cognitive function over time were estimated using a linear mixed model adjusted for demographics, education, vascular risk factors, stroke severity, ischemic stroke subtype, and severity of white matter hyperintensity. We included 570 patients with mild-to-moderate ischemic stroke and baseline data on biomarker levels.

CSF and plasma samples were collected from a retrospective observational cohort of participants with ICH (n = 38). Additionally, we obtained CSF samples from patients who underwent lower limb surgery due to accidental injuries, serving as healthy controls (n = 12).

Furthermore, the concentration of inflammatory factors in the acute-phase CSF was significantly higher compared to both the recovery phase of ICH and healthy control levels. Correlation analyses of inflammatory factors and the patients' CSF metabolites revealed several metabolites associated with central inflammation. Notably, kynurenic acid (Kyna) exhibited a positive correlation with central inflammation and a negative correlation with the Glasgow Coma Scale (GCS). In the collagenase-induced ICH mouse model, elevated levels of Kyna were also associated with increased inflammation in the CSF. Additionally, in vitro studies demonstrated that Kyna regulates inflammatory cytokines by activating microglia.

One hundred and seventy-two patients with 188 intracranial atherosclerotic plaques (100 symptomatic and 88 asymptomatic) with available HRMRI data were recruited. Clinical characteristics and conventional plaque features on HRMRI were measured, including high signal on T1-weighted images (HST1), the degree of stenosis, normalized wall index, remodeling index, and enhancement ratio (ER). Univariate and multivariate analyses were performed to build a traditional model to differentiate between symptomatic and asymptomatic plaques. Radiomic features were extracted from pre-contrast and post-contrast HRMRI. A radiomic model based on HRMRI was constructed using random forests, ridge, least absolute shrinkage and selection operator, and deep learning (DL). A MIX model was constructed based on the radiomic model and the traditional model. Gender, HST1, and ER were associated with symptomatic plaques and were included in the traditional model, which had an area under the curve (AUC) of 0.697 in the training set and 0.704 in the test set. The radiomic model achieved an AUC of 0.982 in the training set and 0.867 in the test dataset for identifying symptomatic plaques. In the training set, the MIX model showed an AUC of 0.977. In the test set, the MIX model exhibited an improved AUC of 0.895, which outperformed the traditional model (p = 0.032). Radiomic analysis based on DL and machine learning can accurately identify high-risk intracranial plaques.</p>","PeriodicalId":23237,"journal":{"name":"Translational Stroke Research","volume":" ","pages":"1745-1755"},"PeriodicalIF":4.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143664577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
