Effect of Xenon on Brain Injury After Aneurysmal Subarachnoid Hemorrhage
Subarachnoid HemorrhageAneurysmal5 moreAn investigator-initiated clinical drug study Main Objective: To explore neuroprotective properties of xenon in patients after aneurysmal subarachnoid hemorrhage (SAH). Primary endpoint: Global fractional anisotropy of white matter of diffusion tensor imaging (DTI). Hypothesis: White matter damage is less severe in xenon treated patients, i.e. global fractional anisotropy is significantly higher in the xenon group than in the control group as assessed with the 1st magnetic resonance imaging (MRI). After confirmation of aSAH and obtaining a signed assent subjects will be randomized to the following groups: Control group: Standard of Care (SOC) group: Air/oxygen and Normothermia 36.5-37.5°C; Xenon group: Normothermia 36.5-37.5°C +Xenon inhalation in air/oxygen for 24 hours. Brain magnetic resonance imaging techniques will be undertaken to evaluate the effects of the intervention on white and grey matter damage and neuronal loss. Neurological outcome will be evaluated at 3, 12 and 24 months after onset of aSAH symptoms Investigational drug/treatment, dose and mode of administration: 50±2 % end tidal concentration of inhaled xenon in oxygen/air. Comparative drug(s)/placebo/treatment, dose and mode of administration: Standard of care treatment according to local and international consensus reports. Duration of treatment: 24 hours Assessments: Baseline data Information that characterizes the participant's condition prior to initiation of experimental treatment is obtained as soon as is clinically reasonable. These include participant demographics, medical history, vital signs, oxygen saturation, and concentration of oxygen administered. Acute data The collected information will contain quantitative and qualitative data of aSAH patients, as recommended by recent recommendations of the working group on subject characteristics, and including all relevant Common Data Elements (CDE) can be applied. Specific definitions, measurements tools, and references regarding each SAH CDE can be found on the weblink here: https://www.commondataelements.ninds.nih.gov/SAH.aspx#tab=Data_Standards.
Evaluation of Functional Recovery of Patients With Acute Ischemic Stroke Treated by Thrombectomy...
Acute Ischemic StrokeThe management of cerebral infarctions (CI) is a real public health issue. The French National Authority for Health recommends Mechanical Thrombectomy (MT) either in combination with Intravenous Thrombolysis (IVT), or alone, after failure of IVT or in case of contraindication to IVT, within 6 hours of the onset of symptoms. The objective is to determine the factors predicting good functional recovery at 3 months in order to establish the typical profile of the "good responder" patient to MT and to evaluate functional recovery at 3 and 12 months (mRS ≤ 2) according to the modality of MT (depending on whether it is performed during the day or at night), the age of the patients, the equipment used for MT, the type of anaesthesia, as well as the impact of the metrics from the radiological evaluation in the patient's management. patient management.
Medication Intake of Solid Dosage Forms: A Risk Factor for Patients With Stroke-induced Dysphagia?...
Cerebral InfarctionStroke3 moreIn a prospective, quantitative explorative study, the risk of aspiration and penetration when swallowing solid pills (placebo) compared to a crushed placebo pill will be evaluated during a routine Fiberoptic Endoscopic Evaluation of Swallowing (FEES). The study design is thus a quasi-experimental study design with repeated measurements in the sense of a pre-posttest. Each patient undergoes a baseline examination (routine procedure) followed by the intervention (administration of three different solid pills and a crushed pill).
Study of the Therapeutic Effects of Cortical Autograft Implantation in Patients With Cerebral Ischemia...
Ischemic StrokeBrain lesions in the adult have dramatic consequences, because the spontaneous capacity of the brain to functionally recover is limited. Besides existing rehabilitative therapeutic approaches (e.g. physiotherapy), several lines of research aim at developing treatments to promote and refine brain plasticity to enhance functional recovery following brain injury. This pilot clinical study aims at enrolling subjects victim of a stroke with neuronal destruction leading to a disabling motor deficit. Usually these patients benefit from intensive neurorehabilitation which allows them to progress up to a certain point but when their recovery plateau is reached; current medicine is disarmed and no effective treatment allows, to date, to improve further their performance. This monocentric pilot study aims at evaluating the feasibility and safety of Autologous Neural Cell Ecosystems (ANCE), which is a cortical autograft intended to be used on stroke patients, for the replacement of motor neurons destroyed during an ischemic stroke.
S100B Kinetic During the Occurrence and Treatment of Delayed Cerebral Ischaemia After a Subarachnoid...
Subarachnoid HemorrhageNearly half of the survivors of subarachnoid haemorrhage (SAH) retain irreversible neurological damage resulting from the early lesions associated with the initial bleeding, and the occurrence of possible delayed cerebral ischaemia (DCI). The early diagnosis of the occurrence of an DCI is therefore a major challenge in order to optimise management before irreversible lesions are formed. However, the means of diagnosis are often not available, and up to a third of DCI are discovered on follow-up images when the lesions are already present. Among the markers of brain injury, S100 calcium-binding protein B (S100B) is an astrocyte protein released into the bloodstream at the time of the appearance of a brain lesion. Its short half-life makes it a prime candidate for patient follow-up to diagnose a new ischemic lesion and assess the effectiveness of its management. Among the elements at the origin of DCI, the occurrence of proximal vasospasm is the main element on which we can have a therapeutic action. The strategy implemented in the department consists of performing a mechanical angioplasty when proximal vasospasm is detected with a decrease in downstream cerebral perfusion. Nevertheless the benefit of this therapeutic action is discussed and there is currently no early marker of the effectiveness of this procedure.

G6PD Deficiency in Infarction Patients in Shaanxi Province
Cerebral InfarctionG6PD DeficiencyCerebral infarction brings heavy burden to patients and families with high morbidity, mortality, disability and recurrence rate. Anti-platelet aggregation therapy plays important role for secondary prevention of cerebral infarction. G6PD deficiency is a rare genetic disorder, patients with this disorder could suffer hemolysis after eating broad beans. Professor Zeng Jinsheng et al found that the hemolysis risk of G6PD deficiency patients was significantly increased when aspirin was applied in Guangdong Province. However, the prevalence of G6PD deficiency in northern China remains unknown, as well as the safety of antiplatelet therapy. To this end, 1000 patients with acute cerebral infarction will be continuously included in 30 second-level and above hospitals in 10 prefectures and cities of Shaanxi Province for observation and follow-up for 12 months, to explore the prevalence of G6PD deficiency in cerebral infarction patients in Shaanxi Province, and to analyze the relationship between G6PD deficiency and the clinical characteristics and prognosis of cerebral infarction. To clarify the efficacy and safety of antiplatelet therapy for G6PD patients with cerebral infarction is of great significance for guiding the individualized treatment of cerebral infarction.
Factors Affecting the Quality of Life After Ischemic Stroke in Young Adults
Ischemic StrokeDespite a generally favourable 3-month functional outcome and a very low mortality, young ischemic stroke (IS) patients face to reduced quality of life associated with a complexity of problems or "invisible dysfunctions" after IS. Better identification and understanding to these factors may improve stroke rehabilitation and stroke self-management programmes, wich will lead to better stroke recovery. The aim of the study is to assess the predictors of the health-related quality of life in young patients under 50 years after ischemic stroke, and to to evaluate specific changes in different dimensions of health-related quality of life during the first year of post-stroke recovery using a standardized battery of neuropsychological tools and stroke specific health-related quality of life measures. In the first phase of the study, 300 IS patients will be enrolled for the validation of the Czech version of the the Stroke Impact Scale 3.0. In the second phase of study, 200 enrolled IS patients (100 young IS patients < 50 years and 100 IS patients of 50-65 years) will undergo a serial of structured and standardized questionnaires during scheduled outpatients' controls three, six and 12 months after IS. In the third phase of study, twenty young IS patients < 50 years will undergo an in-depth, semi-structured interview with explanatory questions that will allow a detailed understanding of the patient's experience. Interpretative phenomenological analysis (IPA) study design will be used.
