Non-alcoholic fatty liver disease as a predictor of recurrent ischemic stroke and transient ischemic attack in carotid atherosclerosis

This retrospective study of 742 patients with carotid atherosclerosis found that non-alcoholic fatty liver disease (NAFLD) is independently associated with increased risk of recurrent ischemic stroke or transient ischemic attack during follow-up. A combined predictive model incorporating NAFLD status, clinical variables, and carotid plaque characteristics demonstrated superior performance in identifying high-risk patients for secondary stroke events.

Ischemic stroke incidence following COVID-19 bivalent booster vaccination in adults 65 years and older

A retrospective cohort study examined ischemic stroke and transient ischemic attack cases within 21 days of COVID-19 bivalent Pfizer vaccination in Kaiser Permanente patients aged 65+, finding an incidence of 34.3 per 100,000. While a safety signal was detected requiring further investigation, the authors appropriately note that validation of any causal association between vaccination and stroke risk is needed before conclusions can be drawn.

Preventability of Ischemic Stroke and Transient Ischemic Attack in a Tertiary Care Center in Argentina

This retrospective study evaluated patients with acute ischemic stroke or transient ischemic attack to assess how many cases could have been prevented through better management of vascular risk factors such as hypertension, dyslipidemia, atrial fibrillation, and smoking. The researchers developed a 10-point preventability scale to classify the degree to which each event was avoidable based on the optimization of modifiable risk factors at presentation.

Protein Biomarkers for Distinguishing Acute Ischemic Stroke from Transient Ischemic Attack: A Meta-Analysis

This meta-analysis examined ten protein biomarkers across 18,160 acute ischemic stroke (AIS) and 3,410 transient ischemic attack (TIA) patients to identify biomarkers that could improve diagnostic differentiation between these two conditions. Five biomarkers showed statistically significant differences between AIS and TIA groups: S100B, sNfl, copeptin, IL-6, and MMP-9, with MMP-9 demonstrating the largest concentration differential.

Cerebrovascular Events After Head and Neck Radiation Therapy: Systematic Review and Meta-Analysis

This systematic review and meta-analysis of 50 studies demonstrates that head and neck cancer patients receiving radiation therapy have a significantly increased risk of ischemic stroke (8.98 per 1,000 person-years) and carotid stenosis compared to surgical or non-treated populations. The relative risk of stroke is approximately 1.3 times higher in irradiated patients, with carotid stenosis incidence ranging from 0-40% depending on follow-up duration.

Pre-stroke sleep quality predicts 1-year mortality and functional outcomes in ischemic stroke and TIA patients

This cohort study of 2,266 stroke/TIA patients found that poor pre-stroke subjective sleep quality (highest PSQI quartile) significantly increased 1-year mortality risk (3.73-fold) and poor functional outcome risk (2.15-fold) compared to good sleep quality. The association remained independent after adjusting for confounders, suggesting sleep quality as a prognostic marker in acute ischemic stroke.

Cervicocerebral atherosclerosis and atrial fibrillation increase long-term mortality in ischemic stroke patients

This study of 406 acute ischemic stroke/TIA patients found that atrial fibrillation combined with high cervicocerebral atherosclerotic burden significantly increased 7-year mortality risk, with those having AF and high atherosclerosis burden facing approximately 3-fold greater mortality risk. The findings suggest that concurrent presence of these two vascular conditions substantially worsens long-term outcomes compared to either condition alone.
