Filter by:Evaluating the collateral circulation of acute ischemic stroke (AIS) mainly depends on the imaging examination. At present, there is no effective and sensitive biomarker for collateral circulation. Thus, the research objective was to evaluate the predicting role of the CBP/P300-interacting transactivator with Glu/Asp-rich C-terminal domain 2 Ratio (CITED2) from peripheral blood mononuclear cells in the collateral circulation of AIS. We classified the AIS patients into two groups (the good collateral group and the poor collateral group) by DWI-ASPECTS score. The western blot was applied to test the protein expression of vascular endothelial growth factor (VEGF) and CITED2. Then, we collected other clinical data. Binary logistic regression analysis between collateral circulation and clinical data was performed. Finally, Receiver operating characteristic (ROC) curve analysis was used to explore the predictive value of the CITED2.
To examine the revascularization efficacy and safety of T-02 and its associated performance characteristics in treatment of appropriately selected subjects experiencing an acute ischemic stroke when the treatment is initiated within 24 hours after last seen well under the current guideline, and to generate hypotheses to be confirmed in subsequent confirmatory clinical investigations
VERIFY will validate biomarkers of upper extremity (UE) motor outcome in the acute ischemic stroke window for immediate use in clinical trials, and explore these biomarkers in acute intracerebral hemorrhage. VERIFY will create the first multicenter, large-scale, prospective dataset of clinical, transmagnetic stimulation (TMS), and MRI measures in the acute stroke time window.
In the Russian Federation, ischemic cerebral infarction is recorded annually in more than 450,000 people. It is the second most common cause of death after coronary heart disease. The 30-day mortality rate after an ischemic cerebral infarction is more than 25%, and during the following year about half of the patients die. To date, all candidate neuroprotective drugs tested in various clinical trials have demonstrated insufficient efficacy . Therefore, the development of new approaches to the treatment of severe brain injuries of various etiologies is one of the most important tasks of critical condition medicine. Brain damage due to stroke triggers a number of pathophysiological reactions, which are based on the accumulation of glutamate with the development of excitotoxicity. The effect of glutamate on NMDA receptors is one of the main factors of neurodegenerative disorders. Xenon is an anesthetic whose neuroprotective properties have been shown in many experimental studies. Хenon inhalation after ischemia and reperfusion suppresses ischemic brain damage and tPA-induced cerebral hemorrhages, and damage to the blood-brain barrier. The most interesting is a randomized controlled trial performed by R. Laitio et al. (2016), in which the use of xenon in combination with hypothermia in clinical practice was studied for the first time. In patients who have undergone community-acquired cardiac arrest, xenon inhalation at a concentration of 40 vol.% within 24 hours in combination with hypothermia, led to less damage to the white matter of the brain than with patients using hypothermia alone. The 6-month mortality rate was 27% in the xenon and hypothermia group and 35% in the hypothermia group. It is important to note that today, despite a large pool of convincing preclinical studies proving the neuroprotective properties of xenon, there is not a single clinical study of its use in ischemic stroke. Therefore, the research objectives is to determine whether the strategy of using xenon-oxygen mixture inhalation is better than oxygen-air mixture inhalation with respect to the change in scores on the NIHSS, Rankin and Glasgow coma scales on day 7, the duration of stay in the ICU and the frequency of nosocomial pneumonia.
A multi-center, prospective, randomized, open-label, adaptive group sequential designed, blinded endpoint assessment (PROBE) clinical trial of endovascular treatment among selected AIS
Study the prevalence of strokes in the emergency department (ED) and their possible eligibility for thrombolysis.
Acute ischemic stroke is the second leading cause of death and disability, and it is also one of the main reasons for the high cost of health care. The major risk factors for stroke are hypertension, atrial fibrillation, and smoking, which are the main intervention targets for primary stroke prevention. Although these recognized risk factors have been adequately treated, there are also significant differences in stroke incidence and outcome in the population. Sleep apnea is a common complication of acute ischemic stroke, characterized by upper airway obstruction and obstructive sleep apnea. Nowadays, more studies are currently investigating CPAP to promote long-term neurological recovery, improve the ability to perform activities of daily living, and reduce the recurrence of cardiovascular disease in stroke patients. However, 25%-50% of patients with sleep apnea will refuse or be intolerant of ventilation with CPAP. High-flow nasal cannula (HFNC) therapy is a revolutionary non-invasive respiratory support option that is widely used in NICU worldwide. This trial aims to investigate the value of different ventilation methods in reducing the rate of pulmonary infections and tracheal intubation in stroke patients. This trial is a prospective randomized cohort study, collecting patients with acute ischemic stroke in the intensive care unit of the Department of Neurology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from 2022.05.01 to 2023.01.31. Participants who met the inclusion criteria were subjected to polysomnography on the first day of admission, and those diagnosed with sleep apnea according to the diagnostic criteria for sleep apnea were randomly grouped. Participants were given different forms of oxygen therapy, such as usual care therapy (nasal cannula and facemask), nasal continuous positive airway pressure (nCPAP), and HFNC oxygen therapy. After one week of observation, the investigators evaluated whether there were differences in the rate of tracheal intubation and pulmonary infection between the groups, as well as the length of hospitalization, hospital costs, and neurological recovery. All enrolled patients were followed up 1 month after discharge.
Hemorrhagic transformation is a common complication of acute ischemic stroke patients . BBB damage is regarded as a major pathophysiological mechanism of hemorrhagic transformation. So, the investigators hypothesis the level of BBB damage biomarker is predictor of intracranial hemorrhage following ischemic stroke.
To evaluate the performance of patent foramen ovale (PFO) device developed by Lifetech Technology (Shenzhen) Co., LTD
The aim of the study was to establish a clinical and advanced imaging database of acute ischemic stroke patients treated with mechanical thrombectomy due to large vessel occlusion of anterior circulation within 24 hours from stroke onset in China, and to investigate the predictors and potential mechanisms of futile recanalization after mechanical thrombectomy.
