Filter by:Stroke is accompanied by local inflammatory response and systemic immunosuppression. Immunosuppression markers are associated with the occurrence of medical complications (infections), whereas inflammatory markers are associated with worse functional prognosis. This prospective study tries to validate in acute stroke patients the prognostic usefulness of a panel of immune biomarkers that have previously been associated with various clinical outcomes. The identification of beneficial and harmful immune responses in cerebral ischemia will allow the prediction of the clinical course of the patients and will be helpful in designing immunomodulatory therapeutic strategies for acute stroke.
The purpose of this study is to evaluate whether general anesthesia or sedation technique is preferable during embolectomy for stroke, measured in terms of three months neurological impairment. In addition we study if there is any difference between the methods regarding complication frequency.
This pilot trial will be the first step toward direct comparison of delivery of endovascular reperfusion therapy to intravenous rt-PA in a time-to-treatment framework shown as most effective by the NINDS rt-PA Stroke Trial. A randomized trial is justified for the following reasons: 1) The high rate of death and disability associated with ischemic stroke despite treatment with intravenous rt-PA mandates critical analysis of alternate therapies with therapeutic potential, 2) endovascular treatment for acute ischemic stroke is expanding in North America without compelling evidence of safety and efficacy from well-designed clinical trials, 3) critical cost-effectiveness analysis cannot be done without acquiring pertinent outcomes data from controlled studies.
Despite abundant evident supporting the use of acute reperfusion therapy in the setting of acute ischemic stroke (AIS), adoption of this practice in routine clinical care is poor. We hypothesize that a significant barrier is the difficulty in weighing the benefits and risks of rt-PA treatment in the care of an individual patient, a problem compounded by the time urgency of decision-making and clinical fears that weigh risks of treatment more heavily than benefits. The goal of this Quality Improvement (QI) study is to leverage an IT solution that we have developed, ePRISM, that executes multivariable risk models with patient-specific data so that a personalized estimate of an individual's outcomes (both risks and benefits) with and without rt-PA, can be generated so support safer, more effective clinical care. Through an earlier project, we will have programmed ePRISM with the best available risk-stratification models and developed a clinically useful format for presenting the data to support clinical decision-making in AIS. Through QI, we propose to identify the optimal mechanism for integrating the tool within the routine flow of patient care in preparation for more definitive studies, or dissemination strategies, to improve the treatment of patients with AIS.
Primary purpose of the trial is to demonstrate the arisen of focal cortical atrophy, localized in the ipsilateral primary motor area, measured in mm, three months after infarction of internal capsule. The patient is compared to himself between day zero to ten and three months. The study hypotheses are: - A focal cortical atrophy of the ipsilesional primary motor area occurs after cerebral infarction of the internal capsule. It is measurable accurately and reproducibly by MRI at three months. Other brain areas within the voluntary motor system will also be explored (supplementary motor area, pre motor area). - This atrophy is correlated with achievement of pyramidal tract, assessed by the fractional anisotropy of its fibers. - This atrophy is correlated with disability at three months, assessed by Rankin score.
The registry of acute stroke under new oral anticoagulants (RASUNOA) is a German multicenter, prospective, observational registry performed at about 50 study centers covering about 50.000 acute ischemic strokes and 6000 acute intracranial hemorrhages per year. Study enrollment will be consecutive. The RASUNOA registry study center is the University Medical Center of the Principal Investigator (Heidelberg, Germany). The registry will focus on treatment decisions and concepts in patients being under treatment with a new oral anticoagulant and suffering from acute ischemic or hemorrhagic stroke.
The aim of this study was to determine the prevalence rate and risk factors for chemical laboratory clopidogrel low-response (CLR) in the acute phase after an ischemic stroke.
The purpose of this study is to determine whether M2 macrophages are safe and feasible in the treatment of non-acute stroke patients
The aim of this study was to determine the prevalence rate and risk factors for chemical laboratory clopidogrel low-response (CLR) in the acute phase after an ischemic stroke.
This randomized trial tests the effect of early blood pressure reduction on major disability and death among patients with acute ischemic stroke in china.
