Filter by:This study is two-center, prospective, randomized, open-label, controlled, investigator-sponsored study that aims to investigate the efficacy of low-dose colchicine in preventing recurrent stroke in the patients with acute atherothrombotic minor-to-moderate ischemic stroke during hospitalization.
The aim of this study is to assess the efficacy and safety of endovascular treatment versus medical management in patients with acute basilar artery occlusion with extended time window of 24-72 hours from onset.
INVISIBLE-1 aims to prospectively follow patients up to one year after ischemic stroke to: 1. Determine the cumulative incidence of occult cancer in patients with embolic stroke of undetermined source (ESUS) and elevated D-dimer 2. Describe occult cancer characteristics and spontaneous course of occult cancer Methodology The investigators will include 370 stroke patients with elevated D-dimer (≥ 820 μg/L) at the time of stroke, suspicion of ESUS after initial workup and without known cancer. The investigators will perform a follow-up telephone interview at one year to assess the occurrence of a new cancer and characterize the course of the disease. Significance Determining the real incidence of occult cancer in high-risk patients will help support the implementation of screening trials in the future. Faster detection and treatment of occult cancers would significantly impact patient' outcomes by offering faster cancer treatment and optimal secondary stroke prevention.
In the high-stakes battle against ischemic cerebrovascular disease, where every second counts and the margin for error is slim, how do the investigators tip the scales in favor of patient survival and improved outcomes? This groundbreaking study, the first nationwide, population-based analysis with long-term follow-up in an Asian context, dives deep into this critical question. Leveraging an expansive dataset from Taiwan's National Health Insurance Research Database, the investigators scrutinize the efficacy and risks of aggressive surgical interventions-specifically, EC-IC bypass, CEA, and CAS-in a cohort of over 84,000 patients. This paper serves as a milestone, bridging the gap between medical idealism and clinical reality. It calls for a surgical renaissance, emphasizing the need for refining techniques and enhancing patient selection protocols. If participants're looking for a comprehensive, nuanced, and, above all, actionable insight into the surgical treatment of ischemic cerebrovascular disease, this is the study that could redefine the paradigm.
Patients with ischemic stroke in the posterior circulation continue to have high rates of mortality and disability, even with aggressive treatment. We wanted to evaluate preoperative imaging to screen patients with a good prognosis from mechanical embolization. We assess the degree of ischemia by defining the pons-midbrain-medulla index (PMMI) and correlate the preoperative PMMI with the clinical prognosis of postoperative patients to verify the validity of PMMI in predicting the clinical prognosis of patients with embolization.
Most stroke patients are initially evaluated at the closest hospital but some need to be transferred to a hospital that can provide more advanced care. The "Door-In-Door-Out" (DIDO) process at the first hospital can take time making transferred patients no longer able to get the advanced treatments. This study will help hospitals across the US "stand up" new ways to evaluate stroke patients, decide who needs to be transferred, and transfer them quickly for advanced treatment.
1. Using neurofilament light chain as a diagnostic tool and predictor of outcome of acute ischemic stroke 2. Using neurofilament light chain in detecting severity in old ischemic stroke
The current study aims to evaluate the efficacy and safety of pBFS-guided cTBS combined with iTBS for the rehabilitation of language functions in patients with post-ischemic stroke aphasia.
Background: Large vessel carotid stenosis represent significant cause of ischaemic stroke. Indication for surgical revascularisation treatment relies on severity stenosis and clinical symptoms. Mild clinical symptoms such as transient ischemic attack, amaurosis fugax or minor stroke preceded large strokes in only 15% of cases. Aim: The aim of this prospective study is to evaluate whether retinal perfusion is impacted in significant carotid stenosis. Automated retinal oximetry could be used to better evaluate perfusion in post-stenotic basin. The investigators presume the more stenotic blood vessel, the more reduced retinal perfusion is resulting in adaptive changes such as higher arteriovenous saturation difference due to greater oxygen extraction. This could help broaden the indication spectrum for revascularisation treatment for carotid stenosis. Methods: The investigators plan to enroll 50 patients a year with significant carotid stenosis and cross-examine them with retinal oximetry. Study group will provide both stenotic vessels and non-stenotic vessels forming the control group. Patients with significant carotid stenosis will undergo an MRI examination to determine the presence of asymptomatic recent ischaemic lesions in the stenotic basin, and the correlation to oximetry parameters. Statistics: Correlation between the severity of stenosis and retinal oximetry parameters will be compared to the control group of non-stenotic sides with threshold of 70%, respectively 80% and 90% stenosis. Data will be statistically evaluated at the 5% level of statistical significance. Results will be then reevaluated with emphasis on MRI findings in the carotid basin. Conclusion: This prospective case control study protocol wil be used to launch a trial assessing the relationship between significant carotid stenosis and retinal perfusion measured via automated retinal oximetry.
This study is a multicenter, randomized, double-blind, placebo parallel control study, aim to evaluate the efficacy and safety of human urinary kallidinogenase in the treatment of acute ischemic stroke with type 2 diabetes.
