Filter by:This study is a multicentre, randomized, double-blind, placebo-controlled, investigator-sponsored study that aims to investigate the efficacy of colchicine in preventing recurrent stroke in the patients with acute minor-to-moderate ischemic stroke or TIA and a hsCRP level of ≥2mg/L.
Endovascular thrombectomy (EVT) enormously improves the prognosis of patients with large vessel occlusion (LVO) stroke, but its effect is highly time-dependent. Direct presentation of patients with an LVO stroke to an EVT-capable hospital reduces onset-to-treatment time by 40-115 minutes and thereby improves clinical outcome. Electroencephalography (EEG) may be a suitable prehospital stroke triage instrument for identifying LVO stroke, as differences have been found between EEG recordings of patients with an LVO stroke and those of suspected acute ischemic stroke patients with a smaller or no vessel occlusion. The investigators expect EEG can be performed in less than five minutes in the prehospital setting using a dry electrode EEG cap. An automatic LVO-detection algorithm will be the key to reliable, simple and fast interpretation of EEG recordings by ambulance paramedics. The primary objective of this study is to develop one or more novel AI-based algorithms (the AI-STROKE algorithms) with optimal diagnostic accuracy for identification of LVO stroke in patients with a suspected acute ischemic stroke in the prehospital setting, based on ambulant EEG data.
The objective of this study is to demonstrate the safety and efficacy of the Penumbra System including Thunderbolt Aspiration Tubing (Thunderbolt) in a population presenting with acute ischemic stroke (AIS) secondary to intracranial large vessel occlusion (LVO) who are eligible for mechanical thrombectomy.
The primary hypothesis being tested in this trial is that ischemic stroke patients in posterior circulation at 4.5 - 24 hours post onset of stroke will have improved clinical outcomes when given intravenous tissue plasminogen activator (tPA) compared to standard care.
Objective: To observe the practical application of the standardized green channel treatment system for stroke in Xi 'an in the real world. Methods: Clinical data and information of patients with acute ischemic stroke who received standardized green channel treatment for stroke were collected, and a multicenter observational clinical study was carried out in the real world to evaluate the prognosis, mortality, incidence of asymptomatic and symptomatic cerebral hemorrhage, incidence of pneumonia, and recurrence rate of stroke after 90 days.
The scientific hypothesis was based on data on the effectiveness of the usage of robotic mechanotherapy and virtual reality technologies. Purpose of the study is the development and scientific substantiation of the effectiveness and safety of rehabilitation programs using the technology of robotic mechanotherapy (exoskeleton) with functional electrical stimulation (FES) and virtual reality (VR) technology with biofeedback (BFB) in restoring walking and balance disorders at the stationary stage of medical rehabilitation in patients in acute and early recovery periods of ischemic stroke. The duration of the study is 2 years. The study is planned to include 120 patients. Anamnesis collection, physical and neurological examination will be carried out for all patients upon admission. Diagnostic transcranial magnetic stimulation, electroencephalography and stabilometry will also be performed upon admission and discharge. Adverse events will be assessed. On the last day of the study, the dynamics of the volume and strength of movements, functional independence and spasticity will be assessed according to the scales (MRC, NIHSS, mAS, mRS, Rivermead, Hauser walking index, Tinetti scale, SHRM, ICF, Tampa scale, EQ-5D-5L), as well as the assessment of mental and cognitive status according to HADs and MoCA. Patients will be randomly divided into 4 groups: 3 main and 1 control. All patients will undergo a basic rehabilitation course. In the first group (exoskeleton with FES): 10 procedures, 5 times a week, the duration of the course of medical rehabilitation is 12-14 days. The total duration of one procedure is 1 hour. In the second group (VR technologies with BFB): 10 procedures, 5 times a week, the duration of the course of medical rehabilitation is 12-14 days. The total duration of one procedure is 30 minutes. In the third group (Complex application of robotic mechanotherapy technologies with FES and VR with biofeedback): 10 procedures, 5 times a week, the duration of the course of medical rehabilitation is 12-14 days. The total duration of training with VR is 30 minutes, then no earlier than 2 hours later, training on an exoskeleton, lasting no more than 1 hour. Patients in the control group will receive comprehensive rehabilitation procedures as prescribed, during the course of treatment accepted in a medical institution.
Background: For moderate to severe carotid artery atherosclerotic stenosis, in the past decades, carotid artery stenting (CAS) has been an alternative to carotid endarterectomy (CEA) for the treatment of carotid artery stenosis. The transfemoral artery (TFA) using Seldinger's technique has been the most commonly used approach for CAS. The radial artery is an ideal puncture site for cerebrovascular intervention. Studies have shown that nerve intervention through radial artery approach can complete most cerebrovascular intervention procedures, including cerebral angiography, carotid artery stent implantation, vertebral artery stent implantation, intracranial artery stent implantation, mechanical thrombectomy, aspiration, intra-arterial thrombolysis and so on. However, the current studies are based on single center small sample studies, and there has been still a lack of large sample randomized controlled experiments to verify the safety and effectiveness of CAS in transradial artery (TRA) . Objective: To evaluate the efficacy and safety of CAS via TRA in patients with carotid artery stenosis through a multicenter, prospective and randomized study. Study design: This study is a randomized, open label, multicenter, parallel controlled trial. A non-inferiority test is performed to compare the primary end point between the experimental group and the control group. The experimental group will undergo carotid stent implantation via radial artery approach, while the control group will use femoral artery approach. Study population: Adult patients with symptomatic carotid-artery stenosis ≥50% or asymptomatic stenosis ≥70%. Study outcomes: Primary end points: The incidence of death, or new-onset stroke, or myocardial infarction, or severe hemorrhage events within 30 days post-procedure Secondary end points:1. The incidence of death, new-onset stroke and myocardial infarction within 48 hours / 30 days post-procedure. 2. The incidence of death within 48 hours / 30 days post-procedure. 3. The incidence of new-onset stroke within 48 hours / 30 days post-procedure. 4. The incidence of myocardial infarction within 48 hours / 30 days post-procedure. 5. The incidence of severe hemorrhage events within 48 hours / 30 days post-procedure. Other end points: 1. Successful rate of DSA. 2. Successful rate of endovascular treatment. 3. Degree of patient-reported comfort. 4. Operation time 5. NIHSS score changes post-operation.6. mRS score score changes post-operation. 7. X-ray exposure. Safety outcomes: 1.Occurrence of all adverse events. 2. AEs related to operation and device. 3. Incidence of adverse event of special interest.
Acute stroke afflicts nearly 700,000 patients in the US and is the number 3 cause of death. Only 2-9% of this large number is treated with t-PA if they arrive within 4.5 hours. An equally small percentage of patients with large vessel occlusion undergo thrombectomy. The thrombectomy patients may or may not receive t-PA. Some of these patients rarely receive intravenous GPIIB/IIIa inhibitors. Many lines of evidence suggest that GP IIb/IIIa inhibitors, a class of FDA approved potent platelet inhibitors that have been used extensively along with heparin for acute coronary syndromes (heart attacks) and unstable angina (chest pain), may be safe enough to give in these circumstances.
In this study, the clinical data of patients with AIS were collected, 16s RNA was used to detect the composition and diversity of intestinal flora, and flow cytometry and mass spectrometry were used to detect intestinal flora-related metabolites in plasma，to explore the influence of gut microbiota and its metabolites on stroke prognosis.
Helsinki University Hospital (HUS) has decided on a strategy to provide digital health care services for several medical specialties - a project called the Health Village (HealthVillage.fi). Within Health Village a specific digital My Path program, iRENE Digital Pathway, has been developed for web-based neuropsychological rehabilitation. iRENE Digital Pathway is a structured program for adults with an acquired brain injury (ABI), which utilizes psychoeducative information and self-evaluation questionnaires for attentional, memory and executive disorders with a feedback, and provides training for internal and external memory and other cognitive strategies. The current study will explore if web-based neuropsychological rehabilitation is a feasible and effective method for carrying out rehabilitation for adults with ABI.
