The study is a double-blind randomized controlled trial, lasting for 15 days for each participant. Patients with post-stroke dysphagia who receive treatment at the Rehabilitation Department are selected as the study subjects. The patients are randomly assigned to either the experimental group or the placebo group. All patients receive routine rehabilitation therapy and swallowing rehabilitation training, along with enteral nutrition support using Intermittent Oro-esophageal Tube. In addition to these interventions, patients in the experimental group receive transcranial direct current stimulation, while the instruments used for patients in the placebo group only illuminate an indicator light without any actual effect.
Acute ischemic stroke has a high incidence, ischemic stroke caused by large vessel occlusion is serious and has a poor prognosis, and its triggers in the short term before onset are not clear. The aim of this study was to evaluate the short-term risk of acute ischemic stroke caused by multiple triggers. In this trial, through a case-crossover study design, patients were asked about the exposure to each trigger in the previous year and the exposure during the preictal risk period (the exposure observed during the risk period) for each potential trigger of acute ischemic stroke caused by large vessel occlusion. To evaluate the relative risk of ischemic stroke resulting from exposure to triggers, comparing exposure during the dangerous period with the usual frequency of exposure. Relative risks and corresponding 95% CIs were estimated for past-year exposure and past-year mean exposure (assessed as chronic risk factors) and time to last exposure (assessed as triggers). Scientifically evaluate exposure to a range of potential triggers, including infection, mood, smoking, alcohol consumption, diarrhea and vomiting, extreme temperature changes, and several factors that increase blood pressure and their risk of developing acute ischemic stroke.
Affecting more than 150,000 patients in France, stroke is a major public health issue and a leading cause of disability worldwide. In western countries, 80-85% of strokes are of ischemic subtype. This study will focus on young adults, aged 18-45, with a diagnosis of ischemic stroke. Studies assessing post-stroke cognition in young patients reported an alarming prevalence of cognitive impairment, affecting about 60% of stroke survivors between 4 and 12 months after the acute event. However, longitudinal data on neurocognitive trajectories (i.e., the evolution of cognitive impairment over time) in young patients with ischemic stroke are lacking. Collecting such data requires an exhaustive neuropsychological assessment and several functional evaluations, at different times, for the same patient. Repeated neurocognitive study of young patients with ischemic stroke will enable: a description of the prevalence of impaired global cognitive efficiency, an analysis of the specific neurocognitive domains affected, and the tracing of trajectories of recovery from cognitive impairment over time, in terms of global cognitive efficiency and as a function of specific neurocognitive domains (memory, executive, attentional, social cognition, instrumental functions, fatigability, etc.). Up to date, the clinic-radiological predictors and associated factors of neurocognitive impairment after ischemic stroke in young patients have not been studied. Ischemic stroke causes acute brain lesions of the gray matter (GM) and white matter (WM). Numerous studies suggest that cognitive health may be more closely linked to the integrity of WM than to GM. Magnetic resonance imaging (MRI), and in particular diffusion tensor imaging (DTI) sequences, analyze WM bundles. By using fiber tracking algorithms image analysis enable the WM fiber bundle reconstruction and allow quantifying the volume of lesions (pre-existing and ischemic stroke-induced) in the WM tract. The aim of this study is to study whether the extension of pre-existing and acute white matter lesions is associated with poorer cognitive recovery after ischemic stroke, both in terms of global cognitive performance and impairment in specific neurocognitive domains.
The study is a prospective multicentre registry study. Patients admitted to 10 stroke centres nationwide from September 2022 to September 2025 with acute ischaemic stroke due to large vessel occlusion considering underlying ICAS and treated with emergency endovascular thrombolysis were included for analysis. Patients who met the general inclusion criteria underwent thrombectomy and the necessary remedial treatment.
Mechanical thrombectomy of acute ischemic stroke caused by major vessel occlusion of the anterior circulation has become an accepted procedure in the last decade. Recent IAT modalities have been classified as suction aspiration,stent retrieval and combination modality. The suction aspiration technique is limited by the possibility of breaking the entire thrombus during the IAT. In addition, the stent retrieval technique is also limited because of thrombus migration during stent removal from an acute-angled artery as in the case of a carotid siphon. According to recent development of suction catheter, investigators expected that suction aspiration will prevent breaking the entire thrombus during the IAT. Investigators will evaluate the radiological and clinical outcome of suction aspiration technique in comparison with combination technique in the large artery occlusion feasible to both suction aspiration and combination technique prospectively in a randomized trial.
The clinical trial is for acute ischemic stroke patients measuring cerebral oxygen saturation (rSO2) values using pulse oximeter of near-infrared spectroscopy in the frontal lesion area and normal area of brain. The purpose of the clinical trial is to compare differences in cerebral oxygen saturation values, and the efficacy and safety are evaluated through additional exploratory clinical trials.
In this study, a multicenter, randomized, controlled, prospective cohort study was conducted to observe the effect of Edaravone Dexborneol on the incidence and outcome of bleeding transformation after thrombolysis in acute ischemic stroke. To explore the methods to reduce the dilemma of bleeding transformation after thrombolysis, and to dynamically detect the changes of the main links causing bleeding transformation such as blood-brain barrier damage, local immune response activation and so on. To explore the mechanism of Edaravone Dexborneol in reducing bleeding transformation. It is proved that Edaravone Dexborneol combined with thrombolytic therapy can reduce the risk of bleeding and transformation after thrombolysis and improve the safety of thrombolysis. Secondly, it can improve the early recanalization rate of ischemic stroke patients after thrombolytic therapy, and effectively protect the integrity of the blood-brain barrier.
The goal of this clinical trial is to learn about efficacy and safety of dual antiplatelet therapy in ischemic stroke with intracranial artery stenosis. The main question it aims to answer are: whether aspirin combined with clopidogrel for 3 month is better than 1 months for patients with non-cardiogenic cerebral infarction with intracranial artery stenosis. Participants will get dual antiplatelet therapy (aspirin plus clopidogrel) for 1 month or 3 months within 7 days of the first stroke. Researchers will compare experimental group (3 months dual antiplatelet therapy) with comparison group (1 month dual antiplatelet therapy), to see if experimental group would reduce stroke recurrence or mortality, and increase bleeding and other adverse prognosis.
Along with the current clinical trial, the efficacy and safety of a 300 mg loading dose of ticagrelor administered within 24 hours of the first-ever large-vessel ischemic stroke compared to 200 mg cilostazol were assessed through NIHSS, mRS, and possible adverse effects.
