Filter by:This study encompasses the maintenance and utilization of a repository of samples from patients with cerebrovascular disease and stroke. The types of tissue taken are blood, cerebrospinal fluid (CSF), tissue, and microdialysis samples. Future analysis of these samples can potentially help investigators to better categorize groups of patients, understand the underlying etiology of these pathologies, identify markers that are associated with favorable or poor outcomes, and track changes that occur during the natural course of the disease or with treatment. This is a prospective observational study which will use samples from such patients to create this library which can be used to explore these questions in the future.
Early thrombolysis is essential in treating ischemic strokes. The time window for thrombolysis is limited to 4,5 hours after symptoms onset. In the French region of Franche Comté, in order to reduce the thrombolytic delay, a telemedicine network was developed between the neurovascular reference unit (NVU) localised in the University Hospital of Besançon and the peripheral hospital centres. Patients may then be transported to the NVU immediately after the thrombolysis initiation. The aim of our study was to assess the relevance of a systematic medicalization of transfer to the NVU of patients with stroke who were telethrombolyzed before. It was a retrospective, monocentric and observational study conducted over 24 months, in Franche-Comte (France).
To evaluate the ability of NICU (NeuroIntensive Care Unit) staff to interpret, before and after a training period, symmetry, sedation level, seizures activities and artefact on continuous cEEG/qEEG (continuous electroencephalography/quantitative electroencephalography) tracings.
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 trial aims at collecting standardized data concerning the early neurological clinical recovery of patients, 3 months after endovascular treatment of an acute ischemic stroke. Although this outcome is a major issue of patients' prognosis, it is rarely collected at this stage of their follow-up.
The investigators design a randomized, control study to evaluate the therapeutic effect of scalp acupuncture using Jiao's motor area for motor dysfunction in ischemic stroke patients using the following outcomes: motor function, activity of daily living,quality of life.
The risk of early recurrence or progression of acute ischemic stroke is very high, even in patients treated with aspirin. The Chance study show that clopidogrel plus aspirin treatment reduced the risk of recurrent stroke in patients with transient ischemic attack (TIA) or minor ischemic stroke (NIHSS ≤ 3) within 24 hour onset and was not associated with increased hemorrhage events, compared with aspirin monotherapy. However, it is not known whether the dual antiplatelet treatment could reduce the risk of early recurrence or progression in patients with acute mild to moderate ischemic stroke (4 ≤ NIHSS ≤ 10). The investigators hypothesise that clopidogrel-aspirin treatment will be superior to aspirin monotherapy in this group of patients.
The aim of this study is to show for the first time that treatment with intravenous fibrinolysis using rt-PA in patients with recent ischemic stroke is accompanied by increases in circulating levels of BDNF, which may reflect an increase in BDNF synthesis in the brain. The analysis of the recovery of functional and cognitive abilities as well as mood at 3 months will allow us to study the impact of BDNF on these parameters. Thus, depending on the results obtained, circulating BDNF could serve as an early marker of these.
The current management of ischemic stroke is based on different strategies that may be combined: intravenous thrombolysis in a stroke ICU, intravenous thrombolysis in a telemedicine procedure, endovascular thrombectomy. Given this now rich therapeutic arsenal, it seems necessary to evaluate practices in local care in the field and the impact of these on the prognosis of ischemic stroke victims. The aim of this observational study is to compare these different care practices without interfering with the choice of strategy. A blood sample will also be taken at different times to study the value of growth differentiation factors (GDF) 8, 11 and 15, and Brain-derived Neurotrophic Factor as prognostic biomarkers
