Filter by:Intracranial atherosclerosis (ICAS) accounts for 10 to 40%, depending on ethnicity, of the 700,000 ischemic strokes in the United States every year. The annual rate of recurrent stroke in patients with optimally treated ICAS remains more than twice the average of other stroke etiologies (12.5% vs. 5). A robust literature has established that vessel wall magnetic resonance imaging (vwMRI) of extracranial carotid vessel wall enhancement (VWE) can predict stroke, independent of stenosis. VWE has been reported in symptomatic ICAS, but the role of local and systemic inflammation is unknown. Inflammatory biomarkers are elevated in symptomatic extracranial atherosclerosis, but the association with vwMRI findings in ICAS has not yet been explored. VWE is typically demonstrated by the uptake of gadolinium MRI contrast into the aneurysm wall or atherosclerotic plaque. A novel MRI contrast agent, ferumoxytol, allows multi-contrast weighting on T1w and T2w images and provides important insight into the role of local vessel wall inflammation by accumulating in macrophages on delayed T2* sequences. To identify effective prevention and treatment strategies for cerebrovascular disease, we need to critically evaluate vwMRI techniques, determine VWE prevalence, and explore the link between VWE and inflammation.
With the development of population aging, the incidence of covert stroke and cognitive dysfunction gradually increased. Currently, there is still lack of prospective cohort study with large sample size on the relationship between perioperative covert stroke and postoperative cognitive dysfunction. The investigators will perform a prospective cohort study. The aim of the study is to determine whether there is an association between perioperative covert stroke and postoperative cognitive dysfunction in elderly patients undergoing noncardiac surgery.
Stroke is a leading cause of morbidity and mortality.Acute ischemia causes irreversible damage to neurons and glial cells, leading to functional deficits and chronic sequelae with variable degrees of spontaneous recovery of function. Stem cells have been shown to enhance recovery through multiple immunomodulatory effects, neoangiogenesis and neurogenesis. We conducted a prospective randomised end observer blinded study to evaluate primarily the safety of intraarterial autologous stem cells delivered to ipsilateral middle cerebral artery in acute and subacute stroke patients (0-15 days post ictus).Secondarily we aimed to evaluate the outcome on the basis of clinical evaluation and follow up imaging
The purpose of this study is to evaluate if 5 consecutive sessions of PathMaker anodal DoubleStim treatment, which combines non-invasive stimulation of the spinal cord (tsDCS- trans-spinal direct current stimulation) and of the median nerve at the peripheral wrist (pDCS-- peripheral direct current stimulation), can significantly reduce spasticity of the wrist and hand after stroke.
This is a observational validation study. The Stroke Clinical Decision Support Tool ( InstaDx) , an information technology application will be adapted and developed in accordance to evidence based clinical practice guidelines ( Level IA). Neurology Residents will be using the InstaDx CDST to improve their diagnostic accuracy and the findings will be validated against the review of a stroke subject expert. The study hypothesis is that Clinical Decision Support Tool used by neurology residents will have an agreement of >0.77 when compared to Stroke Expert (gold standard) in diagnosing type of ischemic stroke.
This project is one multi-center, a prospective cohort study, based on 1660 cases of ischemic stroke patients with the treatment of 3 months, and 21 months of follow-up observation in order to clarify the advantages and characteristics of integrated treatment of traditional Chinese medicine sequela of apoplexy; With the formation of curative effect, to highlight the advantage of the programme of comprehensive treatment of apoplectic sequela in traditional Chinese medicine and its compound preparation; To form a active medical service mode of stroke chronic disease management processes, as well as modalities and mechanisms for the evaluation of the curative effect.
Development and clinical validation of SCALA, a new rating scale for lateropulsion after stroke. A monocentric clinical study including 78 post-stroke individuals and 30 patients without stroke and/or healthy volunteers. In order to analyze the SCALA's content validity, a Delphi-type consensus process was applied prior to clinical validation. The Delphi process, including 20 international experts, has given rise to the version of the scale to be tested clinically (SCALA-V1; Paper in preparation).
The purpose of this study is to test the efficacy of the Stroke Counseling for Risk Reduction (SCORRE) intervention in increasing accuracy of perceived stroke risk and promoting lifestyle behavior change to reduce stroke risk in young adult African Americans.
Stroke is a prevalent atherosclerosis vascular disease with high mortality, external counter pulsation (ECP) is an approved noninvasive therapy for angina, congestive heart failure, myocardial infarction, and cardiogenic shock that augments blood flow to cardiac and systemic circuits, which improves the flow volume in the carotid. Though ECP is Ⅱa recommendation for stroke management, no multi-center control clinical study has been reported for prognosis of stroke. The aim of this study is to evaluate the effect of ECP on stoke. To address this assumption, investigators enroll subjects with ischemic stroke and randomized into control or ECP group, the ECP intervention will be carried out with a standard protocol which involves 35 one-hour sessions (5 days a week) for continuous 7 weeks. The primary endpoint is mRS score in 3 months, secondary endpoints include NIHSS, BI and MMSE score, recurrence of stroke in 3 months, glycolipid metabolism, transcranial doppler (TCD) flow velocities and endothelial function.
The objective of this study is to investigate the value of employing the aortic no-touch off-pump coronary artery bypass technique and the practice of carbon dioxide surgical field flooding for the prevention of type 1 and 2 neurological injuries following surgical coronary revascularization.
