The relationship between prognosis of patients with traumatic brain injury and microRNA biogenesis proteins.

Background: This study aims to investigate whether the expression levels of proteins involved in microRNA (miRNA) biogenesis vary in early- and late-stage traumatic brain injury (TBI) patients and to evaluate its effect on prognosis.

Methods: Dicer, Drosha, DiGeorge Syndrome Critical Region eight (DGCR8), Exportin5 (XPO5), and Argonaute2 (AGO2) levels were measured in the blood samples of severe TBI patients collected 4-6 h and 72 h after the trauma and compared with the control group. Prognostic follow-up of the patients was performed using the Glasgow Coma Scale score.

Carotid Artery Perivascular Adipose Tissue Density and Response to Intravenous Tissue Plasminogen Activator in Acute Ischemic Stroke.

The importance of Carotid Artery Perivascular Adipose Tissue Density (CAPATd), a parameter that can be readily evaluated on emergency computed tomographic angiography (CTA), in acute stroke has not been adequately clarified. We created exploratory logistic regression models to detect the interaction between the effect of CAPATd and intravenous (IV) tissue plasminogen activator (tPA) in 174 patients (mean age 71 ± 14 years, 94 women) with acute ischemic stroke treated with IV-tPA alone. The CAPATd-average mean (-60.

Asymptomatic Cerebral Emboli Following Carotid Artery Stenting: A Diffusion-Weighted MRI Study.

Background: Silent cranial embolism due to carotid artery stenting has been demonstrated to cause dementia, cognitive decline, and even ischemic stroke. The purpose of this study was to compare the periprocedural asymptomatic cranial embolism rates of different stent designs used for extracranial carotid stenosis with diffusion-weighted magnetic resonance imaging.

Methods: A total of 507 consecutive patients who underwent carotid artery stenting at our center from December 2010 to June 2020 (mean age, 66.

Predictors of Symptomatic Hemorrhage After Endovascular Treatment for Anterior Circulation Occlusions: Turkish Endovascular Stroke Registry.

We evaluated the predictive factors of symptomatic intracranial hemorrhage (SICH) in endovascular treatment of stroke. We included 975 ischemic stroke patients with anterior circulation occlusion. Patients that had hemorrhage and an increase of ≥4 points in their National Institutes of Health Stroke Scale (NIHSS) after the treatment were considered as SICH.

Plaque morphology effect on periprocedural asymptomatic cerebral embolism in carotid artery stenting using first-generation carotid stents: A diffusion-weighted magnetic resonance imaging study.

Background: Silent cerebral embolism with carotid artery stenting (CAS) may contribute to dementia and cognitive decline. Moreover, clinically silent embolism is an important index of peri-procedural stroke risk.

Aims: The purpose of this study was to compare the periprocedural asymptomatic cerebral embolism rates of CAS procedures performed for noncalcified and calcified carotid artery plaques using diffusion-weighted magnetic resonance imaging (DW-MRI).

Six-year outcomes of carotid artery stenting performed with multidisciplinary management in a single center.

Objective: This study aimed to evaluate the first 30-day results of clinical, periprocedural asymptomatic cranial embolism, and long-term restenosis of the multidisciplinary conducted and evaluated carotid artery stenting (CAS) procedure in our patient group with real-life data.

Methods: A total of 610 patients who were subjected to consecutive CAS procedures in our center between December 2010 and February 2019 were clinically and radiologically followed up for a mean duration of 6 years. Of the 610 patients, 274 (45%) were symptomatic for carotid artery stenosis, whereas 336 (55%) were identified as asymptomatic.

The association of the circle of Willis anomaly and risk of stroke in patients with carotid artery disease.

Results: In this retrospective study, we analyzed 175 patients who presented at our outpatient stroke clinic between January, 2013 and June, 2015 with either unilateral symptomatic or asymptomatic carotid artery disease, and who had had CT angiography imaging performed. Demographic properties, carotid artery stenosis and the anomaly of the circle of Willis was recorded.

Conclusion: There was no statistically significant difference in patients with symptomatic and asymptomatic carotid artery disease in terms of the anomaly of the circle of Willis.

Evaluation of mean platelet volume and platelet distribution width in patients with asymptomatic intermediate carotid artery plaque.

Background: Platelets play a significant role in the pathogenesis of atherosclerosis. In atherosclerotic plaques, the risk of plaque rupture is more crucial than the severity of the stenosis they cause. Non-calcified carotid artery plaques are more unstable than calcified plaques, and they are associated with a higher risk of rupture, thromboembolism, and consequently, stroke.

Is Elevated Neutrophil-to-Lymphocyte Ratio a Predictor of Stroke in Patients with Intermediate Carotid Artery Stenosis?

Objective: An increased neutrophil-to-lymphocyte ratio (NLR) is associated with poor clinical prognosis in patients with cardiovascular disease. In this study, we aimed to investigate if there was a correlation between NLR and the risk of stroke in patients with intermediate carotid artery stenosis.

Methods: A total of 254 patients with a 50%-70% stenosis in the carotid artery, 115 of whom were symptomatic and 139 of whom were asymptomatic, were included in the study.

Predictors of Symptom Development in Intermediate Carotid Artery Stenosis: Mean Platelet Volume and Platelet Distribution Width.

Platelets play an important role in the pathogenesis of atherothrombosis. Platelet activation is associated with increased mean platelet volume (MPV) and platelet distribution width (PDW). In this study, we investigated the relation of MPV and PDW with the risk of stroke in patients with intermediate (50%-70%) carotid artery stenosis.
