Acute ischemic stroke is a leading cause of death worldwide, and intravenous thrombolysis with recombinant tissue plasminogen activator rt-PA within 4.5 hours of symptom onset is the most effective treatment currently available. However, some patients experience stroke progression and early reocclusion after thrombolysis, which can worsen neurological outcomes. This trial evaluates whether early antiplatelet therapy with oral aspirin, given soon after thrombolysis, can improve recovery without increasing bleeding risks. The study randomly assigns patients to receive either early oral aspirin within 3 hours of starting intravenous thrombolysis or a placebo, alongside the best medical care based on current guidelines. Aspirin is administered as a 300 mg dose, either chewed or given via nasogastric tube if swallowing is difficult. The trial includes a control group receiving placebo under similar conditions to compare outcomes. This is a Phase 3, multicenter, quadruple-blind, randomized clinical trial. During the study, participants will be closely monitored for neurological status and functional recovery using the modified Rankin scale at 30 and 90 days after stroke, as well as other assessments like NIH Stroke Scale scores within the first week. Researchers will track early neurological changes and safety outcomes such as intracranial hemorrhage. Follow-up will include evaluations at multiple time points up to 90 days post-stroke to determine the effects of early antiplatelet treatment on stroke recovery.

Researchers are evaluating whether providing free near or distance vision correction glasses can slow cognitive decline in older adults aged 60 to 79 years who have vision impairment but normal baseline cognition and hearing. The study focuses on participants living in rural areas to see if vision correction reduces cognitive decline over 36 months in a cost-effective way. The trial compares cognitive changes between those receiving glasses and those who do not during the study period. Participants are randomly assigned to one of two groups. The intervention group receives free customized glasses based on their prescription and pupillary distance, with options to select frames. These participants will have yearly eye exams to update their prescriptions and can get replacement glasses if lost or damaged. The control group receives an eyeglass prescription but no free glasses during the study however, free glasses will be provided at the end of the trial if needed. During the 36-month study, participants undergo cognitive assessments at baseline, 12, 24, and 36 months using the Chinese version of the Global Cognitive Score Scale. Regular eye exams and monitoring of adherence to wearing glasses are included for the intervention group. The study aims to measure differences in cognitive decline rates between groups while monitoring vision changes and providing necessary support throughout the trial.

Researchers are studying patients who have had an acute ischemic stroke caused by a blockage in a large blood vessel in the brain. The trial focuses on the safety and effectiveness of remote ischemic conditioning RIC as an additional treatment to improve recovery after endovascular thrombectomy, a procedure that removes the blockage. This research addresses the challenge that even when blood flow is restored, many patients still have poor outcomes or die, possibly due to brain injury during and after the procedure. The study compares three groups one receiving only endovascular thrombectomy and best medical care, a second group receiving thrombectomy plus RIC treatment for 14 days, and a third group receiving thrombectomy plus RIC for 30 days. RIC is a noninvasive device treatment where a cuff on the upper arm inflates and deflates in cycles, applied once before thrombectomy and twice daily afterward. Best medical management follows clinical guidelines for all groups. Participants will be monitored closely for 90 days after stroke. Researchers will assess recovery using the modified Rankin Scale to measure functional independence and will record neurological improvements, brain infarct size, adverse events, and quality of life. The study includes imaging, neurological exams, and safety checks at multiple time points, including 24 hours, 14 days, 72 hours, and 90 days post-treatment to evaluate the impact of RIC on stroke outcomes.
