Active clinical trials for "Ischemic Stroke"

Neuroglobin has shown rich neuroprotective effects against cerebral ischemia and hypoxia, and therefore has the potential to impact outcomes after acute ischemic stroke. Hypoxia inducible factor (HIF)-1α is neuroprotective in several models of experimental brain injury and is increased in brain after acute cerebral infarction in humans and experimental animals.The investigators sought to examine the changes in serum neuroglobin and HIF-1α concentrations in patients with acute ischemic stroke during the initial 96-h period after stroke and assessed the relation between them and the relation of them to prognosis of such patients with acute ischemic stroke.

The purpose of this study is to study the safety and feasibility of mobilization of acute ischemic stroke patients treated with IV-tPA between 12-24 hours of treatment.

Ventilator-associated pneumonia (VAP) is an important cause of morbidity and mortality in ventilated critically ill patients specially in intensive care unit (ICU). It is associated with an increased duration of mechanical ventilation, high death rates and increased healthcare costs in China. However, VAP is preventable and many practices have been demonstrated to reduce the incidence of this disease, but the morbidity is still so high. So much more methods of prevention should be needed to reduce the incidence of VAP. Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) present anti-inflammatory and immunomodulatory effects besides their ability to regulate cholesterol composition. So it is hypothesized that early use of statin may prevent some of the infection disease such as VAP. Actually, Two studies have showed that statin treatment is associated with reduced risk of pneumonia. However, the relationship between statins and reduced risk of pneumonia is not consistent. After reviewing some of the guidelines,meta analyses and system reviews, the investigator find that advanced age,immune suppression from disease or medication and specially depressed level of consciousness are the risk factors of VAP. So the investigator assumes that early use of statin may give us a favorable outcome in the patients with coma or in the patients with severe disease (Acute Physiology and Chronic Health Evaluation II score > 15 or Glasgow coma score < 7). In addition there is no prospective study to investigate the role of statins in VAP in the patients with ischemic stroke. The investigator hopes that this study can approve the relationship between statins and reduced risk of VAP in the patients with ischemic stroke. And it can improve the processes,outcomes and costs of critical care as well.

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 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 describe the amount and pattern of physical activity in stroke patients in the first week after admission. The investigators hypothesis is that patients are inactive for most of the time during hospitalization, activity being correlated with severity of stroke, but not with age, BMI and sex.

The primary objective of the present randomized controlled trial is to compare the effectiveness of three anti-smoking interventions of different intensities. It has been hypothesised that early follow-up visits facilitate post-stroke smoking cessation in patients hospitalized because of first-ever ischemic stroke.

Through 5 years continuous observation of acute ischemic stroke patients in Neurology Department of Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology, clinical data about emergency treatment (neurological score, examination and treatment), medical data after admission (neurological score, inspection, examination and treatment) and long-term prognosis (neurological score) was collected. The outcomes were set as the score scale, all blood test index and examination index of the research objects at specific period after illness. Through statistical analysis and comparison of different in-hospital clinical data in predicting the outcome of the patients, our study will provide more evidence-based solutions for the treatment and prediction of acute ischemic stroke.

This study is a French multicenter prospective study including 5 stroke units with available MRI and F-MISO PET for patients with acute ischemic stroke. Background and Purpose: 18F-Fluoromisonidazole (FMISO) PET has been used to identify hypoxic tissues in animals and stroke patients. While MRI has become the gold standard acute stroke imaging, no published study has compared FMISO PET and MRI. The aim of this prospective study is to identify hypoxic tissues in 40 patients with acute ischemic stroke with F-MISO PET and to compare the location and the outcome of these hypoxic cells with MRI datas (weighted diffusion and FLAIR) and to clinical outcome.

A multi-site, interventional, non-comparative, single-arm trial to evaluate the safety of the Keeogo™ Dermoskeleton in subjects with hemiparesis due to ischemic or hemorrhagic stroke.

The primary outcome of this study is to determine the quantitative increase in connectivity, as measured by fMRI brain and calculated as a percent increase from baseline in patients with ischemic stroke. Eligible patients will receive a listening session of music or spoken word listening, 30 days to 5 years following ischemic stroke. Assessments will include modified Rankin Scale, National Institute of Health Stroke Scale, functional Magnetic Resonance Imaging, motor function tests, and neuropsychological evaluations. Assessments occur at baseline, day 45, and day 90 after starting listening sessions.

Severe stroke remains an important cause of mortality and morbidity, despite advances in disease management, acute treatment and secondary measures. Among all post-stroke complications, pneumonia constitutes a major complication with a strong impact on morbidity and mortality. Research also showed that a reduction in respiratory muscle and abdominal muscle strength contributed to pulmonary and respiratory dysfunction following a stroke. Low respiratory muscle function decreases the efficacy of rehabilitation because it leads to exercise intolerance in stroke patients. Thus, special exercise programs are needed to improve the pulmonary function and respiratory muscle strength of stroke patients The aim of pulmonary rehabilitation program is to enhance respiratory muscle resistance during breathing, thereby improving respiratory function. Previous studies demonstrated that pulmonary rehabilitation programs improved respiratory functions in cardiac disease and chronic obstructive pulmonary disease patients
