Predictive factors of outcome of mechanical thrombectomy after acute ischemic stroke

Clopidogrel is an anti-platelet agent used to inhibit blood clots. Variation in response to clopidogrel has been reported among different population and may lead to reoccurring ischemic events. The aim of the present study is to evaluate the incidence of clopidogrel resistance in ischemic stroke patients from different ethnicities in Northern Israel and to find different strategies to overcome high platelet reactivity including clopidogrel dose adjustment or the choice of alternative agents. Quantification of platelet aggregation will be determined by vasodilator stimulated phosphoprotein (VASP) assay.

Aim of the study is to evaluate the usefulness of interleukin 33 in the blood plasma in patients with the acute ischemic stroke of the brain in relation to mode of treatment (thrombolysis, thrombectomy, no treatment), risk factors in correlation with other inflammatory state markers (hsCRP, morphology with smear ). Blood is collected on the first and seventh days of stroke. The purpose is to clarify utility of IL 33 as a biomarker of acute stroke.

In the present study, the investigators aim to elucidate the role of T-cells on cognitive decline in younger stroke patients, using repeated cognitive testing, brain imaging, and immunological analyses in the first 6 month after stroke. The examiners will investigate (i) the extent and duration of stroke-induced changes in T cell function within the peripheral blood of patients; and (ii) post-stroke cognitive functions.

In this prospective, unicentric, case-control study, the main aim is to analyze joint movement and walking patterns in patients with acute stroke with a marker-free motion capture system. Case group: Stroke patients who fulfill the inclusion criteria are invited to participate in the study during admission. The evaluation consists of a workout designed by expert rehabilitation physicians and neurologists that is performed by the patient in front of the Microsoft Kinect camera. The custom-built software Akira record the joint angles of body trunk and upper limbs during the workout. The kinematic data will be analyzed with a machine learning algorithm that classifies the participant according to the kinematic data in normal movement or impaired movement (with the degree of impairment) by age decade. Control group: healthy participants (without neurological or osteomuscular diseases) matched by age and sex with cases 1:1. The correlation between kinematic and clinical scales (NIHSS) and functional scales (modified Rankin Scale) will be analyzed. A secondary objective will be to analyze the predictive value of the kinematic measurements with the functional outcome at three months

In this study, we want to continuously record the interaction of 50 stroke survivors with their smartphones during the first 3 months after discharge. The linkage of smart phone use to function and quality of life will be assessed with standardized outcome measures at defined time points.

Our key objective will be to investigate if geographic proximity to first- and second-degree relatives has an influence on post-acute stroke survival and use of health and social services. We will also model and map spatial variation in stroke and cardiovascular disease (CVD) incidence and mortality and see if some of the variation is due to spatial clustering of familial risk. The study will use innovative approaches to large-scale registry and survey data and statistical analysis on the full Norwegian population. We will integrate multigenerational and geographical information. This will enable us to assess key determinants on stroke survival and use of health and social care at municipality level.

The aim of the work is to; elucidate how the presence of carotid stenosis influence the pattern of stroke and also how it interact with other risk factors for stroke. Also identify predictors of intracranial stenosis and outcome in patients with carotid stenosis with or without intracranial stenosis.

As human beings live longer, geriatric disease develop, one of which was stroke whose prevalence elevated by aging. Increased spasticity is a common symptom after stroke and may hinder patient from rehabilitation. The spasticity was evaluated by subjective judgement before. However, in the recent studies, the electrophysiological test, an objective evaluation, showed possibly positive correlation with the spasticity. They compared stroke patients' hemiplegic side with non-hemiplegic side by H/M ratio which showed significant difference. The stroke patients included in studies had stroke onset over 2 years. Therefore, investigators wonder if H/M ratio can evaluate spasticity in stroke patients onset within 2 years and if H/M ratio is correlated to spasticity.

Stroke is the fifth leading cause of death in the United States and the leading cause of disability. However, in China, stroke is one of the most frequent causes of death and chronic disability. Ischemic strokes in adults younger than 45 years of age were regarded as a relatively uncommon event in the proportion of <5% of all ischemic strokes.
