Filter by:Our institution implemented a protocol to administer an emergent IV dye preparation for stroke alert patients requiring advanced neuroimaging. The emergent IV dye preparation consists of diphenhydramine 50 mg IV once, famotidine 20 mg IV once, and dexamethasone 10 mg IV once, followed immediately by Computed Tomography (CT) Angiography and/or CT Perfusion.
The aim of this study is to establish an academic, real-world, single-center, observational registry of consecutive patients hospitalized with acute ischemic stroke (AIS) due to large vessel occlusions (LVO), treated with either endovascular therapy (EVT) or best medical management (BMM).
The study will make an association between the diagnosis of traditional Chinese medicine that establishes that the syndrome of blood stagnation generates alteration in blood flow, vascular dysfunction, and damage to the endothelium. This process is like what occurs in a stroke. It will use electroacupuncture to change this chronic inflammatory process, and to know the effects and efficacy of this technique in the regulation and modulation of to treat extensive inflammatory diseases. However, this inflammatory response must be associated with serum cholesterol levels, since they are associated with a stroke between the LDL-C/HDL-C ratio and the prognosis after a stroke.
In this study we want to develop and validate a PREM for patient with ischemic stroke.
Background: Recanalization strategies have radically changed the outcome in a significant part of stroke patients. The unpredictable occurrence of cerebral edema (CE) and hemorrhagic transformation (HT) are frequent events in patients affected by ischemic stroke, even when an effective vessel recanalization has been achieved. These complications, related with blood brain barrier (BBB) disruption, remain difficult to prevent or treat, and antagonize the beneficial effect of successful recanalization, leading to poor outcome. Aim: to shed light on the reperfusion injury biological bases, this study aims at evaluating the effects of circulating and imaging biomarkers in relation to CE and HT both in stroke patients and in a coherent murine stroke model. A close interaction between clinical and preclinical research could lead to a broader understanding of the results deriving from the individual lines of activity, allowing a deeper interpretation of the underlying phenomena. Methods: The clinical setting is a retrospective observational study enrolling consecutive patients with acute ischemic stroke in the anterior circulation territory, treated with reperfusion therapies, at Careggi University Hospital in Florence (Italy) from October 1, 2015 to May 31, 2020. In this cohort, the investigators will apply a new approach to assess the presence of CE and HT after stroke in CT scans, through the quantification of anatomical distortion (AD) (induced by fluid extravasation in brain tissue) at 24 hours. A large panel of blood biomarkers related to inflammation, endothelial dysfunction , and fibrin resistance to lysis, will be measured as blood samples are taken from each patient before and 24 hours after thrombolysis or thrombectomy. The role of both AD and blood biomarkers as predictors of 3 months functional outcome, assessed by modified Rankin Scale (mRS), will be estimated. Using a translational approach the investigators will develop a new mouse model of light-induced occlusion/reperfusion of the middle cerebral artery (MCA) to better reproduce the human setting. Then, the investigators will assess functional impairment induced by stroke with and without recanalization at different time points and the investigators will assess through ex vivo experiments the insurgence of BBB alterations 24 hours after the lesion. Finally, the investigators will characterize the stroke volume and the inflammation one week after stroke.
Time is one of the most important in the decision of treatment of acute ischemic stroke. The optimal One-stop management from admission to recanalization associated with reduction of in-hospital times. The development of flat-detector computed tomography perfusion capable angio-suite allowed One-stop management to be improved treatment time better and better. To compare One-stop management versus our standard workflow in shortening door-to-recanalization time.
The investigators propose to perform serial detailed cognitive, motor, behavioral, and blood collection follow-up using longitudinal structured telephone interviews of an anticipated 350 ICH survivors enrolled in Minimally Invasive Surgery Plus Alteplase for Intracerebral Hemorrhage Evacuation (MISTIE) III and ENRICH trials to identify specific cognitive and motor impairment and to perform RNA sequencing to evaluate for evidence of chronic inflammation. The investigators' expected sample size in 2022 accounts for mortality attrition of 10%/year.
Prehospital providers encounter patients with suspected stroke frequently. Prehospital providers need tools to help triage large vessel stroke patients to comprehensive stroke centers. This device will identify large vessel stroke to ultimately improve triage decisions and optimize outcomes.
The aim of the study is to compare the effects of specific functional task-oriented motor imagery training combined with the Bobath Therapeutic Approach and physical practice after imagery on upper extremity motor function in stroke patients.
Overall Design: a multicenter, randomized, double-blind, placebo-controlled, parallel-group, dose-exploration study. Main outcome: 1.To evaluate the efficacy and safety of XY03-EA tablets in the treatment of acute ischemic stroke.
