Filter by:Investigators hypothesized that the precise regulation of blood pressure based on the changes of cerebral blood flow parameters under TCD monitoring can better improve the state of cerebral blood flow, reduce the risk of early neurological deterioration and improve the prognosis of the patients.
This study investigates the clinical practices, safety and effectiveness of Cerebrolysin in routine treatment of patients with moderate to severe neurological deficits after acute ischemic stroke.
The German Stroke Registry (GSR) Endovascular Treatment is an academic, independent, prospective, multicentre, observational registry study. Consecutive patients treated with endovascular stroke treatment will be enrolled in German stroke centers. Patients receive regular care and data will be collected as part of clinical routine. Baseline clinical and procedural information as well clinical follow-up information during in-hospital stay, and up to 90 days of stroke onset are collected. Data collected include demographics, National Institute of Health Stroke Scale (NIHSS) on admission, pre-treatment ASPECTS, information on timing and success of interventional treatment, procedural complications, intracranial hemorrhage, and functional outcome.
This is a prospective open enrollment biorepository to collect and evaluate blood and tissue collected during cerebrovascular procedures, which will then be used for the purposes of identifying biological markers, inflammatory cell infiltrates, and biological states in stroke and other cerebrovascular diseases in the human condition. The study population will include up to 1000 subjects with cerebrovascular disease or suspected cerebrovascular disease. Male and female participants 18 years of age and older will be enrolled. This protocol covers the procurement of biological samples from patients undergoing any cerebrovascular surgery and/or neurointerventional clinical procedure at University of Kentucky. Control participants will include patients undergoing non-emergent, elective diagnostic cerebral angiography as well as patients undergoing emergent angiogram cases. This study represents the first time that tissue, clot and blood will be evaluated for the markers, proteins, and cytokines in human subjects undergoing cerebrovascular procedures. By starting with the human condition, the investigators aim to minimize this loss in translation. Overall, this study will have a great impact on our knowledge of stroke pathology. In essence, this could fundamentally change not only how the investigators develop treatment strategies for the stroke patient population but allow us to individualize the treatment dependent on time after stroke, age, sex, and co-morbidities. Molecular techniques that are impractical when delivered systemically could be delivered locally to impede the early inflammation. This research aims to advance understanding of cerebrovascular disease and to support the development of improved therapies.
Clinical Trial to Evaluate the Efficacy and Safety of JPI-289 in Patients With Acute Ischemic Stroke
The objective of the study is to determine the safely of Human Umbilical Cord Blood mononuclear cells by Intravenous injection in acute ischemic stroke patients.
The goal of this study is to show the efficacy and safety of heparin and nadroparin in the acute phase of ischemic stroke. Therapeutic agents are administered at intervals of 4.5 to 2 hours after onset of clinical signs. Overall administration of anticoagulant agents will test 72 hours. Randomized patients will be divided into three groups. The first group of patients will receive heparin intravenously at the beginning of 2500 UI bolus intravenously, followed by intravenous pump 1000 UI / h (18-20 IU / kg / hr) to reach 2-2.5 times the baseline aPTT. After 24 hours, patients will receive the group Nadroparin subcutaneously in the therapeutic dose. Second group of patients will be administered subcutaneously Nadroparin the therapeutic dose as recommended. The third group of patients are those who will receive placebo intravenously and 24 hours after receiving nadroparin subcutaneously in the therapeutic dose. All patients will receive after 24 hours of starting treatment 100 mg of aspirin per orally. For initiation of treatment will be assessed: - Modified Rankin Scale, National Institutes of Health Stroke Scale, inclusion, exclusion criteria - Sign the informed consent and patient randomization - Laboratory parameters: glucose, creatinine, GGT, K, Na, Cl, blood count, basic coagulation - Women of childbearing age (pregnancy test) - History, clinical presentation, medical history, basic internal review of the status (blood pressure, pulse, body temperature, etc.). - Initial CT examination of the brain - EKG - USG sections of extracranial carotid and vertebral arteries - special hematology factors If a patient meets all the necessary criteria, he may be given the test substance. During the first 24 hours will be monitored at regular intervals vital functions. After 24 hours, each patient received subcutaneous Nadroparin the therapeutic dose and also 100 mg of aspirin per orally. In the interval from 24 to 30 hours of starting treatment the patient will be made: - Control CT brain - EKG - Basic coagulation - Reduction to stop treatment for newly identified haemorrhage or severe and extensive focal cerebral ischemia by CT scan - special hematology factors 72 hours, 7, 30 and 90 days after starting treatment, the patient's clinical evaluation using the Modified Rankin Scale, National Institutes of Health Stroke Scale and Barthel Index. Safety endpoints: mortality, adverse side effects, bleeding
This study seeks to evaluate the efficacy and safety of mildronate injection in treating acute ischemic stroke
Stroke is the leading cause of adult disability in Europe and United States and the second leading cause of death worldwide and affects more than 10,000 Danes each year. Studies in a late and stationary phase after stroke have shown that physical rehabilitation is of great importance for survival and physical ability of these patients, however many studies show that patients lie or sit next to their bed under hospitalization for more than 88.5 % of the daily hours. Physical activity in stroke patients has never previously been measured immediately after debut of symptoms; furthermore there is no knowledge about the optimal dose of physical rehabilitation for these patients. Accelerometers, small measuring devices, are a relatively new way to measure physical activity precisely, and hence it is possible to obtain an objective measure of how active stroke patients are in the first week after admission. The accelerometers measure a variable voltage, depending on the range and intensity of movement. They can measure movement dependent of the placement of the accelerometer, for instance over the hip, arm or leg. Studies confirm their reliability, even in patients with abnormal gait, such as stroke patients. Another approach of studying the effects of physical activity and rehabilitation is through the examination of biomarkers. Studies have shown that biomarkers released during physical activity can inhibit biomarkers released after tissue injury in the brain, as seen after stroke. These brain biomarkers cause further damage and studies show that the higher the levels, the higher the damage. It is therefore obvious to examine whether physical activity rehabilitation can down regulate this destructive process in patients with stroke. Clarification of the optimal dose of physical activity in stroke patients immediately after debut of symptoms and examination of both the biochemical aspects of physical rehabilitation as well as the optimal dose of physical rehabilitation is of great importance for many patients, their relatives as well as of a great socioeconomic importance. The purpose of the project is to investigate feasibility of treadmill training on a weight-bearing treadmill in the acute phase after admission after an ischemic stroke. Furthermore we wish to investigate the acute inflammatory response after ischemic stroke and whether it changes with treadmill training.
The primary objective of this study is to compare effectiveness of five different neuroprotectants, including butylphthalide, edaravone, citicoline, cerebrolysin, and piracetam, among patients with acute ischemic stroke. The secondary objectives of the study are as follows: - To compare safety of five different neuroprotectents, including butylphthalide, edaravone, citicoline, cerebrolysin, and piracetam, among patients with acute ischemic stroke. - To compare cost-effectiveness of five different neuroprotectents, including butylphthalide, edaravone, citicoline, cerebrolysin, and piracetam, among patients with acute ischemic stroke.
