Filter by:A study to examine the safety and potential effectiveness of the adult stem cell investigational product, MultiStem, in adults who have suffered an ischemic stroke. The hypothesis is that MultiStem will be safe and provide benefit following an ischemic stroke.
Primary objective and endpoint is the analysis of the long-term course of lyso-Gb3 and its clinical correlation to the progression of the cardiomyopathy in N215S-Fabry patients.
The purpose of this trial is to assess the safety and effectiveness of the Penumbra System as an adjunctive treatment to intravenous (IV) recombinant human tissue plasminogen activator (rtPA)in patients with acute ischemic stroke from large vessel occlusion in the brain. IV rtPA is the only drug approved for the treatment of acute ischemic stroke but it does not work very well in cases where the stroke is caused by a large vessel occlusion. The hypothesis being tested is to determine if the addition of a treatment by a mechanical thrombectomy device like the Penumbra System can improve the clinical outcome of the patient over just using IV rtPA alone.
The purpose of this study is to evaluate the effectiveness of the medication levodopa, in combination with speech-language treatment, on the language outcome of study subjects with nonfluent aphasia (i.e. difficulty with the comprehension and expression of spoken and written language) following a stroke.
Cardiovascular risk functions fail to identify more than 50% of patients who develop cardiovascular disease. This is especially evident in the intermediate-risk patients in which clinical management becomes difficult. The purpose of this study is to analyze if ankle-brachial index (ABI), measures of arterial stiffness, postprandial glucose, glycosylated hemoglobin, self-measured blood pressure and presence of comorbidity are independently associated to incidence of vascular events and whether they can improve the predictive capacity of current risk equations in the intermediate-risk population.
This prospective observational study will investigate the frequency of new onset atrial fibrillation (AF) and of further cardiac arrhythmias as well as of (clinically silent) cerebral lesions in endurance runners before, during and after the BMW-Berlin Marathon 2011.
Astragalus membranaceus (AM) is used to treat stroke for a long period, and a number of studies have known that AM can reduce cerebral infarction area and has anti-oxidation. Hemorrhagic stroke will induce secondary peri-blood clot edema and that may increase intracranial pressure to exacerbate clinical symptom. Therefore, the purpose of the present study was to investigate the effect of AM on hemorrhagic stroke edema. The investigators selected 80 hemorrhagic stroke patients , and who the stroke is first attack, they were randomly divided into control and experimental groups, and each group was 40 patients as follows: 1) control group, accepted AM placebo 2.8 g three times per day (tid) treatment for continuously 14 days from second day of admission or operation, except standard ordinary treatment; 2) experimental group, accepted AM 2.8 g tid treatment for continuously 14 days from second day of admission or operation, except standard ordinary treatment. Computer tomography (CT) examination was done at first day, 4th day and 7th day of admission, respectively. The ratio of brain edema was calculated by CT image, and inflammatory index including the levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR)，Creatine Kinase BB Isoenzyme (CMBB). D-dimer from venous blood also were measured. In addition, the score including Glasgow outcome scale (GOS), Modified rankin scale (MRS), Function independence measure (FIM), Barthel index (BI) was recorded one week, four weeks and 12 weeks after admission or surgical operation, as an index for clinical symptoms. The index for the therapeutic effect of AM was according to above-mentioned the ratio of brain edema, inflammatory index and clinical symptoms. The investigators expected the results of the present study may provide a scientific evidence for the hemorrhagic stroke edema treatment of AM, thus, the present study may contribute to use the method of integrated Chinese and Western Medicine for the treatment of stroke, and to the research of Chinese Medicine.
Transient ischemic attack (TIA) is a transient neurological deficit (speech disturbance, weakness…), caused by temporary occlusion of a brain vessel by a blood clot that leaves no lasting effect. TIA diagnosis can be challenging and an expert stroke evaluation combined with magnetic resonance imaging (MRI) could improve the diagnosis accuracy. The risk of a debilitating stroke can be as high as 5% during the first 72 hrs after TIA. TIA characteristics (duration, type of symptoms, age of the patient), the presence of a significant narrowing of the neck vessels responsible for the patient's symptoms (symptomatic stenosis), and an abnormal MRI are associated with an increased risk of stroke. An emergent evaluation and treatment of TIA patients by a stroke specialist could reduce the risk of stroke to 2%. Stanford has implemented an expedited triage pathway for TIA patients combining a clinical evaluation by a stroke neurologist, an acute MRI of the brain and the vessels and a sampling of biomarkers (Lp-PLA2). The investigators are investigating the yield of this unique approach to improve TIA diagnosis, prognosis and secondary stroke prevention. The objective of this prospective cohort study is to determine which factors will help the physician to confirm the diagnosis of TIA and to define the risk of stroke after a TIA.
ENCHANTED is an independent, investigator initiated, international collaborative, quasi-factorial randomised controlled trial involving a package of 2 linked comparative randomised treatment arms, which aims to address 4 key questions in patients eligible for thrombolysis in the acute phase of ischaemic stroke. (1) Does low-dose (0.6 mg/kg) intravenous (i.v.) recombinant tissue plasminogen activator (rtPA) provide equivalent benefits compared to standard-dose (0.9 mg/kg) rtPA? (2) Does intensive blood pressure (BP) lowering (130-140 mmHg systolic target) improve outcomes compared to the current guideline recommended level of BP control (180 mmHg systolic target)? (3) Does low-dose (0.6 mg/kg) intravenous (i.v.) recombinant tissue plasminogen activator (rtPA) reduce the risk of symptomatic intracerebral haemorrhage (sICH)? (4) Does the addition of intensive BP lowering to thrombolysis with rtPA reduce the risk of any intracerebral haemorrhage (ICH)? The rtPA dose arm of the study addressing questions (1) and (3) concluded with a publication of the results in May 2016. The BP intensity arm of the study addressing questions (2) and (4) concluded with a publication of the results in February 2019.
The purpose of this study is to determine whether injections of botulinum toxin (commonly known as BOTOX®) into the affected hand of Stroke patients, while targeting the muscles controlling the hand, will lead to improved use of the hand when compared to injections of placebo (a substance that looks similar to the study drug but contains no active study medication).
