Active clinical trials for "Stroke"

The composition of the intestinal microbiota is associated with the risk of stroke and with post-stroke neurological evolution. At the same time, the genetics and epigenetics of each patient are associated with the composition of the intestinal microbiota. The study of the microbiome in stroke patients will allow finding new therapeutic targets for the treatment of stroke patients. For the study, samples will be collected from those patients with ischemic stroke who come to the hospital while the study is being carried out, taking into account certain criteria: the patients must be over 18 years of age, have suffered an ischemic stroke (demonstrated by resonance or head CT), not have any additional serious illness or unstable medical condition, and not be included in clinical trials with neuroprotective drugs. On the other hand, the control group will be asymptomatic, and will be made up of people who have not previously suffered a stroke or a cardiovascular event and who do not have diseases that affect the digestive tract. The main variables of the study are the risk of stroke and disability after a cerebrovascular accident (measured by mRS at 3rd month). Microbiota, genetic and epigenetic variables are also taken into account, such as the presence and levels of bacteria, dysbiosis, genetic polymorphisms and levels of methylation in CpG islands.

The study aims to describe the functional level of the patients who received high intensity gait training during inpatient stroke rehabilitation at discharge, three, six and twelve months after stroke. These data will determine if the observed gains from the high-intensity gait training are retained after discharge from inpatient rehabilitation.

The main aim of the study is to investigate the prevalence and characteristics of ischemic stroke patients with atrial fibrillation and concurrent carotid atherosclerosis. Additionally, this study will investigate the effect of concurrent carotid atherosclerosis on the outcomes of recurrent stroke, myocardial infarction and death during follow-up

In Canada, the number of stroke survivors is equivalent to the size of one of the four Atlantic Provinces. The incident rate of stroke has been increasing steadily since 1995. The majority of the stroke survivors lose upper extremity function, resulting in diminished activities of daily living (ADL). Many therapeutic interventions are recommended to improve upper extremity function or ADLs of stroke survivors, however, Mirror Therapy (MT), inexpensive intervention, can be self-administered by stroke survivors with intact cognition. Thus, the research question is whether a self-administered MT technique improves acute stroke patients' upper extremity motor function and recovery?

The prediction of motor recovery in the acute phase of stroke is crucial for several clinical reasons: (i) informing the patient and his relatives, (ii) helping to identify the patient's endorsement (return home or rehabilitation) as well as the adaptation of the rehabilitation program to what can be expected from it. To date, an algorithm (decision tree) proposed by C. Stinear's team named PREP2 is the best predictive tool with 75% of patients well classified at 3 months. It predicts the functional recovery of the upper limb after stroke 3 months before the episode by categorizing recovery as "excellent", "good", "limited" as well as "minor" (poor). With two data (SAFE score, age) or three (SAFE score, Motor evoked potential, NIHSS), the prediction is effective three times out of 4. In the study we are proposing "PREP-UCV", we would like to validate this algorithm as it is with patients in our active file who are victims of stroke. The expected accuracy is 75% or more. As a secondary objective, we would like to confirm that we find the same algorithm starting from the initial data from PREP 2 (side of the stroke, type of stroke (ischemic and / or hemorrhagic), involvement of the corticospinal tract on MRI, sex at birth ) as well as two other factors which are also very important: cognitive status (dysexecutive / aphasia / neglect), as well as the neutrophils on lymphocytes ratio.

The ROSSETTI registry is an ongoing investigator-initiated prospective study recruiting deidentified demographic, clinical presentation, site-adjudicated angiographic, procedural, and outcome data in acute ischemic stroke (AIS) consecutive patients treated with mechanical thrombectomy (MT) across 10 Comprehensive Stroke Centers in Spain. The registry started in June 2019 and therefore incorporates the more recent device technology

Stroke is one of the major causes of neurological disability in adults globally. Fifteen million patients suffer from stroke annually throughout the world, from which 5 million had to continue to live with a major disability. Especially in developing and non-developing countries, it contributes significantly to the mortality and morbidity. The improvements in medical care of acute stroke, especially in a specialized stroke unit setting, reduced overall mortality of the disease. However, the general prognosis of stroke survivors did not improve accordingly, so that many survivors have to deal with different forms of disability. Following a stroke, patients usually suffer from variable degrees of disability. They require acute treatment at an inpatient setting and extensive assistance throughout their recovery at home. Most stroke survivors depend on informal caregivers, who usually is a family member (eg, spouse) providing unpaid care for the patient.Caregivers are usually unprepared and unfit for such a support after discharge. And as a result, they may experience a decline in their physical and mental health status, social life and general well-being The current study sought to examine the musculoskeletal problems of the informal caregivers in relation with the physical condition and the degree of disability of the patient they are caring. To our knowledge this study can be considered as the first of its kind by evaluating the symptoms of the caregiver from their viewpoint and relates the level of their symptoms to the level of incapacity of the stroke patient.

This study aims at assessing the proportion of patients suffering from neuro-visual troubles (visual-spatial and/or visual-perceptual ), after cerebellar strokes.

stroke is a leading cause of morbidity and mortality worldwide. More than half (54.5%) of the 56.9 million deaths worldwide in 2106 were due to the top 10 causes. Ischemic heart disease and stroke are the world's biggest killers, accounting for a combined 15.2 million deaths in 2106. These diseases have remained the leading causes of death globally in the last 15 years. Recent clinical trials have shown that endo-vascular thrombectomy is an effective and safe recanalization modality for acute ischemic stroke patients . Meta-analysis results show that endovascular treatment is associated with a high ratio of successful recanalization rate and a low rate of symptomatic hemorrhage . Approximately 2.2-37.5% of patients with acute ischemic stroke might encounter early neurological deterioration (END). Definition of END: An increase in NIHSS ≥4 or an increase in Ia of NIHSS ≥1 within 72 h after recanalization treatment.

The investigators hypothesize that transcranial direct current stimulation (tDCS) can improve upper limb motor recovery in the sub-acute phase of stroke patients. This is a randomized, controlled, double blind, cross-over, multicentre, clinical trial.
