Filter by:Clinical and experimental data suggest that neutrophil activation and extravasation are deleterious in acute ischemic stroke (AIS) involving an increased risk of unfavorable outcome and hemorrhagic transformation (HT). However, clinical trials targeting neutrophil recruitment in AIS patients were negative. Recently, an experimental study has shown that neutrophil activation and transmigration begin immediately after the occlusion. Inhibition of neutrophil recruitment several hours after the start of ischemia appears therefore too late to have a clinical relevance. The objective is to study the time dependent impact of neutrophils in AIS and the predominant mediators in each time point to identify the appropriate therapeutic target and time window.
The registry is the main objective exhaustive list of cases validated stroke brain on a geographical area defined to calculate an incidence.
This study evaluates the use of Colchicine in adults over 40 years of age who have suffered an ischaemic stroke or transient ischaemic attack NOT caused by cardiac embolism or other defined causes. Patients will be randomised to 0.5 mg/day of Colchicine plus usual care, or to usual care alone. To investigate the efficacy of low dose colchicine (0.5mg/day) plus usual care (defined as antiplatelet, lipid-lowering, antihypertensive treatment, and appropriate lifestyle advice) compared with usual care alone to prevent non-fatal recurrent ischaemic stroke, myocardial infarction, cardiac arrest, hospitalization for unstable angina and vascular death after ischaemic stroke or transient ischaemic attack (TIA) not caused by cardiac embolism or other defined causes unrelated to atherosclerosis
This study explores the possible implications of the increase in perceived body size for rehabilitation of motor functions. In a recent study we have tested if motor abilities of patients with stroke improve wearing magnifying lenses, showing that a beneficial effect of magnifying lenses can be observed in some patients. In the present study, we will identify 12 patients from this cohort who demonstrated an improvement greater than 10% in one or two motor task when wearing magnifying glasses. These participants will be invited to take part in a clinical study in which they will undergo a training phase: subjects will wear magnifying lenses at home for 30 minutes daily for 14 days while completing a jigsaw puzzle; a log will be kept to document participation. Participants' performance on different motor tasks will be assessed before, immediately after and 1 month after the training session. Standardized measures of motor performance will include the the Action Research Arm test and the Rivermead Assessment of Somatosensory Performance (RASP). In addition, participants will undergo grip strength, finger tapping tasks and a reaching and grasping task. We expect the repeated use of magnifying lenses to generate an improvement of patients' performance across tasks and this effect to be persistent in time.
Among the sequelae of stroke, gait disorder is directly linked to the degree of autonomy in the daily life of patients. It is considered significant effects on their Quality of Life(QOL). Further methods of rehabilitation are required for convalescent patients to recover their function soon and better, due to a multitudes of recovery patient with troubles such as gait problem. This trial is studying to investigate the effects of gait training with a functional electrical stimulation (FES) `WalkAide[R](WA)' to improve the lower-limb function and ambulation in convalescent stroke patients.
Main idea perception of written stories and in pictures among impaired right hemisphere patients Abstract The right hemisphere is considered to complement the language processing abilities of the opposite hemisphere; it is responsible for the processing of secondary and unusual characteristics of linguistic stimulates. This processing enables, among other functions, the comprehension of metaphors and humor. Additionally, it enables the execution of inferring from spoken and written discourse. Studies which deal with common impairments among right-hemisphere-damaged (RHD) individuals, found that inference processing of written stories and narrative sequences presented in pictures was impaired. This impairment could damage the ability to create global coherence, which is an important component of central theme comprehension of different types of narrative. Another important component is superstructures, schemas which aid creating, remembering and producing the main ideas of spoken and written discourse. Other studies consider impairment in creating global coherence, or Theory of Mind impairment, as the source of central theme comprehension impairment among RHD individuals. Discourse is an integral part of interpersonal communication, and of proper social conduct. The themes chosen for conversation reflect the functional role of discourse from semantic and pragmatic points of view. The aim of the current study is to deepen the current knowledge concerning central theme comprehension among RHD individuals following cerebrovascular accident (CVA), in two genres of written discourse (classic stories and stories with a twist), and in situations represented by single pictures. Unlike written stories, the extraction of the central theme out of a single picture requires focusing on a single situation and relying on non-linguistic visual information. Differences concerning central theme comprehension in the different discourse genres and in the pictures might be able to assist in selecting diagnostic and therapeutic tools designed to work on high cognitive-linguistic abilities, which are usually impaired among RHD individuals. In later stage, these tools are meant to help improving RHD individuals' spontaneous narrative skills. The study will include 20 RHD adults following CVA, and 20 healthy adults without any known damage to the right hemisphere. The two groups will be matched concerning sex, age, educational level and socio-economic status. The subjects will perform the study tests during three sessions, 60 minutes each. The screening tests will include language diagnosis - Western Aphasia Battery (WAB), and reading test no. 37 included in the Psycholinguistic Assessments of Language Processing in Aphasia's battery (PALPA). Patients diagnosed with aphasia will be excluded from research. The research tests will include: central theme comprehension test in stories and pictures, including classic stories, stories with a twist, and pictures of different situations (each will be accompanied by a multiple-choice question concerning the central theme), sub- exanimations taken from "Frigbi" battery designed to evaluate memory and phonological memory capacity, Raven's Progressive Colored Matrices test designed to evaluate pre-morbid abilities (non-linguistic), Theory of Mind (T.O.M) evaluation test, and tests designed to evaluate central coherence impairment: Navon Figures test for evaluation of global visual perception impairment, and Rey-Osterrieth Complex Figure Test (RCFT) - Recall Form test for evaluation of visual-perceptive organizational ability, and non-verbal memory. The performances of the two groups will be compared in each test using statistical tests. In addition, the interaction between all variables will be measured.
RATIONALE: The previous study resulted that the gait training using Functional Electrical Stimulation (FES) improved the ankle joint function and the walking ability for the chronic stroke patients with foot drop. In addition, the further exploratory study in multicenter obtained the result that the training with WA were especially good adaptation to the patients who have slight paralysis and can walk independently. PURPOSE: This multicenter prospective trial is studying to reveal whether the gait training with the WalkAide[R](WA) for chronic stroke patients who can walk independently is superior to gait training with a physical therapist.
The goal of this study is to: 1. Assess the usability of the SynPhNe device in a home environment. 2. Evaluate the efficacy of the SynPhNe home use device to improve motor hand function in chronic stroke subjects when used with a few sessions of standard care, as compared to standard care alone.
Thrombectomy is now the standard of care of revascularization in acute ischaemic stroke. Data tend to show that final neurologic outcome is superior if the thrombectomy procedure was performed under conscious sedation. The Rothschild Foundation is a high output centre with more than 400 thrombectomy procedures every year. We report a rate of 5% of these procedures requiring general anesthesia despite conscious sedation being the standard of care. This study aims to identify clinical factors associated with a risk of conversion of a conscious sedation to a general anesthesia.
Stroke treatment includes thrombolysis, thrombectomy for patients with proximal artery occlusion and sometimes neurosurgery. It rises questions regarding hemostasis: thrombolysis induces fibrinolysis but its effects on coagulation, fibrinogen and platelets and duration of these effects are unknown. Thus management of antithrombotics and hemostasis during thrombectomy and surgery is an issue. Objectives : to describe thrombolysis-induced hemostatic disorders (fibrinolysis, coagulation, fibrinogen, platelets) in patients requiring thrombectomy for stroke and to evaluate the time required for the normalization of these disorders. Methods : Observational monocentric study including rtPA-treated patients requiring endovascular treatment for stroke. Blood sampling within the first 48 hours after rtPA administration to assess of fibrinolysis, coagulation and platelet functions with point of care devices and specific laboratory tests. Record of clinical and biological data.
