Filter by:The objective of this study is to create a comprehensive, real-world, multi-center observational registry of consecutive patients admitted to hospitals with acute ischemic stroke (AIS) caused by large vessel occlusions (LVO), who are treated with either endovascular therapy (EVT) or the best available medical management (BMM).
The MATISSE (Molecular Analysis of Thrombus for Ischemic Stroke prognosis and Etiology) project evaluates the hypothesis that the molecular composition of cerebral thrombus in metabolites, lipids, and proteins conditions the clinical prognosis at 3 months of the infarction and informs on its etiological subtype
The best reperfusion strategy for medium-sized vessel occlusion (MeVO) is not well established. Given the proven treatment effect of intra-arterial thrombolysis in patients with large vessel occlusion (LVO), the investigators hypothesized that intra-arterial tenecteplase (TNK) could increase the recanalization rate of MeVO and thus improve clinical outcome. The current study aimed to explore the safety and efficacy of intra-arterial TNK in patients with MeVO.
The potential benefit of intraarterial tenecteplase in acute basilar artery occlusion (BAO) patients with successful reperfusion following endovascular treatment (EVT) has not been studied. The current study aimed to explore the efficacy and safety of intraarterial tenecteplase in acute BAO patients with successful reperfusion after EVT.
A recent pilot study suggests intra-arterial tenecteplase (TNK) during the first pass of endovascular treatment (EVT) seems safe, may increase first-pass reperfusion and good outcome in acute ischemic stroke (AIS) patients with large vessel occlusion (LVO). The study aimed to determine the efficacy and safety of intra-arterial TNK administration during EVT in AIS-LVO patients.
Quantitative EEG (qEEG) has been used as an effective tool in the diagnosis and prognosis of brain-related diseases. In the literature, a variety of qEEG parameters have been proven informative in the prognosis of stroke. In addition, it has been demonstrated that changes in certain qEEG parameters during traditional/task-specific rehabilitation approaches are correlated with clinical outcomes of functional motor recovery. Repetitive transcranial magnetic stimulation (rTMS) has been proposed as a non-invasive and therapeutic treatment used to accelerate and enhance the recovery process of motor function in stroke patients. Many studies have reported that inhibiting contralesional rTMS may have positive effects in stroke patients with severe upper extremity motor impairment. In this context, the aim of the proposed study is to investigate whether there is a correlation between the change in qEEG parameters and the improvement of motor functions associated with rTMS treatment and to provide an electrophysiological prognostic biomarker of inhibiting contralesional rTMS for stroke patients.
Present study aims to track the post-stroke cognitive trajectories and to investigate its inter-individual variability.
Prospective observational multi-center study with the aim to organise and simplify the care pathway through a pragmatic approach to acute stroke imaging powered by cutting edge advances in image processing and artificial intelligence.
Most ischemic stroke patients are in recovery phase, often accompanied by motor impairment, but they lack effective treatment. The appearance of nerve growth factor (NGF) promotes the development of neuroprotective therapy, but it has little effect on stroke because of the blood-brain barrier (BBB). Electroacupuncture (EA) has been used for stroke, while there is no significant clinical effect for recovery phrase. Consequently, we will conduct a multicentre, randomised, controlled, assessor-blinded clinical trial to assess the effectiveness and safety of EA combined with NGF treatment on ischemic stroke recovery.
Post-stroke cognitive impairment(PSCI) refers to a clinical syndrome characterized by cognitive impairment that occurs after a stroke event and persists for 6 months. PSCI is divided into post-stroke cognitive impairment non-dementia and post-stroke dementia. About one half of patients develop PSCI within the first year after stroke. Recent large international cohort studies have reported that the incidence of PSCI is 24%-53.4%, among which the incidence of cognitive impairment after stroke without dementia is 14%-29% and the incidence of dementia after stroke is 11%-42%. A study in China shows that the incidence of PSCI is 53.1%. Our previous small sample study also found that the incidence of cognitive impairment in acute phase of ischemic stroke patients was 64.52%. It can be seen that the incidence of PSCI is high, which is an important health problem. The mortality rate of stroke patients complicated with PSCI is significantly higher than that of patients without cognitive impairment. The 5-year survival rate of patients with post-stroke dementia is only 39%, while the survival rate of stroke patients without dementia of the same age is 75%. In addition, patients with PSCI will lead to long-term disability, a significant decline in self-care ability of daily living, quality of life and mental health status, poor social participation ability, and increased care pressure. If not intervened in time, will bring serious disease and economic burden to the family and society. Therefore, preventing the occurrence and delaying the progression of PSCI is an important task to be solved urgently. Rehabilitation is an important intervention to delay the progression of PSCI, aiming to promote the remodeling of the central nervous system, and the main method is early and multi-dimensional cognitive function training. Some studies have confirmed that computerization, multi-cognitive domains, and adaptive cognitive training (7 consecutive weeks, 5 days a week, 30 min a day) can significantly improve the global cognitive function of patients with cognitive impairment after subcortical stroke and non-dementia . A recent systematic review showed that cognitive training can improve the cognitive function and daily living ability of patients with mild PSCI. It also has a certain effect on the improvement of patients' overall cognitive function. It can be seen that cognitive training is not effective for all stages of PSCI patients, and the effect of cognitive training is very limited for patients who have developed into a single dimension of severe damage, serious overall cognitive impairment even dementia. This suggests that targeted cognitive intervention for patients at the acute stage of stroke may achieve the purpose of preventing the occurrence and delaying the progression of PSCI. Therefore, this study innovatively proposed the concept of preventive cognitive training for patients with acute stroke. In the basis of literature research, combined with the views of the cognitive domain experts and Kang Fushi reformed the existing cognitive training plan, build the computer-assisted ladder multidimensional cognitive training scheme, the main dimensions set up on the basis of cognitive training program, according to the degree of cognitive impairment at the same time set the difficulty level of the project, It is convenient for medical staff to select appropriate items and difficulties based on the dimension and degree of cognitive impairment of patients. To evaluate the effect of cognitive training by using cognitive function scale, psycho-psychological scale, self-care ability scale and other tools, and to clarify whether acute preventive cognitive training can improve PSCI, so as to provide a practical basis for the prevention and intervention of PSCI.
