Filter by:Our aims is to evaluate the equality in efficacy and safety between direct aspiration technique and stent retriever thrombectomy procedure in anterior circulation strokes in a multicenter, prospective study.
The Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.
The primarily goal of the research is to better understand progression of disease in patients who present with an acute stroke to the Hamad General Hospital (HGH) stroke and Transient Ischemic Attack (TIA) clinic. The investigators are specifically interested in patients who have diabetes and have a stroke. The patients enrolled into the research will have detailed clinical evaluation and their imaging studies (MRI and Doppler) will be reviewed. After informed consent, subjects will be examined in the stroke Ward /TIA clinic upon recruitment, and later at less than 48 hours of recruitment (blood extraction and urine samples) and for follow up visits at 1 month+/-7 days (clinical evaluation and to extract blood and urine samples), at 3 months (telephonic conversation only) and at 1 year (clinical and repeat MRI brain). During the initial visit at the ward the investigators will collect serum and plasma for proteomic and metabolomic studies. These will be repeated at less than 48 hours and at 1 month+/-7 days. Investigators will test the effects of risk factors such as diabetes/stroke on the endothelial procoagulant and inflammatory state at onset and evaluate if best medical control leads to improvement in such markers.The repeated studies will determine if better management and presence of certain blood biomarkers can predict or translate to slower progression of disease and correlate it with clinical status.
This study aims to assess the effectiveness of Stroke Unit in the Philippines by comparing the functional outcome between those patient admitted in the general neurology wards and stroke units using modified Rankin Scale
Eighty community-living individuals in Uppsala municipality will be included. Intervention: Outdoor walking exercise program and one strength exercise. Methods: Clinical assessments, questionnaires and medical records. Assessment of motor function, cognition, level of physical activity, food intake and perceived stress are performed at screening as baseline measurements. Walking capacity, mobility, handgrip strength, body composition and cardiovascular risk markers will be assessed at baseline and after 12 week of training. At one year after training health-related quality of life, another cardiovascular incidence and mortality will be documented.
Very early after the onset of the focal perfusion deficit, excitotoxic mechanisms can lethally damage neurons and glia. Excitotoxicity triggers a number of events that can further contribute to tissue death. Such events include peri-infarct depolarizations (PID) and cortical spreading depolarization (CSD) within the peri-infarct zone or ischaemic penumbra. Noninvasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) are emerging as promising tools, owing to their effects on modulating cortical activity. Experimental studies have indicated that cathodic polarization of the cortical surface blocks initiation of CSD. Moreover, it has been recently demonstrated in murine stroke models that cathodal tDCS exerts a measurable neuroprotective effect in the acute phase of stroke, decreasing the number of spreading depolarizations and reducing the infarct volume by 20 to 30%. The investigators propose here a pilot study, in acute middle cerebral artery stroke patients, with a double blind randomization: cathodal tDCS versus sham tDCS. The duration of this study will be two years. Fifty acute middle cerebral artery stroke patients will be included. The tDCS will begin within 4.5 hours of symptom onset. The main criteria of evaluation will be the extent of diffusion-weighted imaging (DWI) infarct volume between imaging on admission and 24 hours later. The investigators propose the hypothesis that in acute stroke patients, cathodal tDCS could be an adjuvant approach to recanalizing therapies.
Recent observational studies have found an association between general anaesthesia and increased post-operative mortality in acute ischemic stroke patients undergoing endovascular treatment. It is unknown whether there is a causal relationship in this observation. The investigators are performing a large randomised trial of general versus local anaesthesia to definitively answer the question of whether anaesthetic type alters perioperative outcome.
Hyperglycemia is common during acute ischemic stroke. However, the optimal strategy to control hyperglycemia during acute ischemic stroke has not been established. The object of this multicenter randomized controlled study is to determine the efficacy and safety of early initiation of subcutaneous once-daily insulin glargine, in comparison with regular insulin, based on a protocolized sliding scale regimen to achieve proper sugar control in acute stroke patients with hyperglycemia admitted to the intensive care unit.
Early after stroke, patients often have significant motor impairment and sensory deficit. Evidence has demonstrated heightened plasticity and significant recovery in the acute phase (first months) post stroke but there has been a lack of effective and practical protocols and devices for early intensive sensorimotor therapy.This research study will conduct a randomized clinical trial of an intensive motor-sensory rehabilitation on patients with acute stroke using a wearable rehabilitation robot. The primary aims are to facilitate sensorimotor recovery, reduce ankle impairments, and improve balance and gait functions. This clinical trial will be conducted on the Study and Control groups of acute stroke survivors.
Although cardio-embolic etiology of ischemic stroke (IS) is largely respected, there is still no clear recommendation for routine complex cardiological examination in all IS patients. Using complex cardiological examination the investigators expect: 1. more accurate detection of patients with concomitant heart disease (cardiac rhythm disorder, valve disorders, acute coronary syndrome, cardiac thrombus and myxoma, atrial and ventricle septum defects) 2. higher number of etiologically determinated IS, which is crucial for accurate secondary prevention.
