Filter by:The purpose of this research study is to learn how people distribute their visual attention when looking at objects nearby versus far away, and why vision may become distracted at near versus far distances.
The purpose of this study is to evaluate a standardized, system-based, barrier assessment and interactive educational intervention to increase appropriate t-PA use for stroke.
We will test whether robot driven, goal directed, trajectory corrected exercise enhances motor outcome in the upper limb of stroke patients better than matched motor activity on an upper body ergometer (monark).
Treatment of acute stroke is still difficult and the only specific drug approved (rtPA) can only be administered if treatment starts within 3 hours after onset of symptoms. This results in a still too small number of patients treated with rtPA ( < 15% in best clinical care institutions ). Ancrod is a differently acting biological drug which has been used for a long time but not for acute stroke treatment. STAT was the first RCT of medium size to show a significant benefit/risk ration if treatment starts within 3 hours. ESTAT was designed closely related to STAT but with a longer 6 hours window and specifically extended inclusion/exclusion criteria to avoid secondary complications possibly related to a longer time window.
The project is a passive follow-up of the Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study cohort. Originally, this was a large, randomized, double-blind, placebo-controlled, 2x2 factorial primary prevention trial testing the effects of alpha-tocopherol and beta-carotene supplementation on cancer incidence and mortality. The study was conducted in Finland as a collaboration between the U.S. National Cancer Institute (NCI) and the National Public Health Institute of Finland. NCI has maintained passive surveillance of the cohort through Finnish national registries, including the cancer registry. The primary purpose of the ATBC cohort follow-up is to use the existing risk factor data and biological specimens (i.e., serum, whole blood, DNA, red blood cells, and toenails) to test hypotheses relevant to cancer etiology, survival, early detection, and prevention. These data and biospecimens continue to provide an invaluable resource for the study of biochemical, nutritional, genetic, and molecular hypotheses. These analyses are made all the more informative and powerful by the addition of cases identified annually during the follow-up period, and the research benefits from a longer pre-diagnosis period (now over 30 years).
This clinical evaluation is a prospective, single-arm, multi-center trial. The purpose of this clinical evaluation is to assess the safety and effectiveness of the Penumbra System in the revascularization of patients presenting with acute ischemic stroke secondary to intracranial, large vessel, occlusive disease.
The purpose of this study is to compare 2 training programs using robotic exercise devices to supervised arm exercises in stroke patients with chronic stable deficits.
The purpose of this study is to modify and develop measures that reflect outcomes that are relevant to recovering Veterans and are sensitive to improvements resulting from innovative gait interventions.
Undernutrition after stroke is frequent and is due to cognitive impairment, visuospatial perceptive deficits, hemiparesis, depression and dysphagia. The impact of intensive nutritional supplementation on functional outcome measures in undernourished stroke patient has not been studied.
Citicoline is a safe drug approved in some countries for the treatment of acute ischemic stroke. The drug has shown some evidence of efficacy in a pooled analysis, based on four clinical trials done in USA with oral citicoline.The purpose of the study is confirm the results obtained in the pooled analysis, that is, evidence of efficacy in the treatment of acute ischemic stroke
