Filter by:This study is aimed to establish reference intervals of NOAC (dabigatran, apixaban and rivaroxaban) in ethnic Chinese patients.
Preprocedural predictors of outcome in patients with acute basilar artery occlusion (ABAO) who underwent endovascular treatment (EVT) remain controversial. Our aim was to analyze if pre-EVT diffusion-weighted images cerebellar infarct volume (CIV) was a predictor of 90-day outcomes.
The objective of this study is to evaluate the safety and efficacy of a single intravenous administration of JTR-161 (allogeneic stem cell product derived from the dental pulp of healthy adult humans) to patients with acute ischemic stroke. This study is comprised of 3 cohorts and conducted in the order of Cohort 1, Cohort 2 and Cohort 3. Cohort 1 Arm-1: JTR-161, 1 × 10^8 cells/subject, 6 subjects Arm-2: Placebo, 2 subjects The Data and Safety Monitoring Board (DSMB) and the Sponsor will decide whether Cohort 2 can be initiated or not. Cohort 2 Arm-1: JTR-161, 3 × 10^8 cells/subject, 6 subjects Arm-2: Placebo, 2 subjects DSMB and the Sponsor will decide whether Cohort 3 can be initiated or not and the dose of JTR-161 in Cohort 3. Cohort 3 Arm-1: JTR-161, 1 × 10^8 cells/subject or 3 × 10^8 cells/subject, 30 subjects Arm-2: Placebo, 30 subjects
The objective of this study is to evaluate the impact of Viz LVO in hospital systems with non-interventional and interventional (spoke and hub) stroke centers on the timing and outcomes of patients with suspected acute ischemic stroke indicated for mechanical thrombectomy.
This study is aimed to depict the epidemiological trend, aetiologies, clinical characteristics, treatment options of IS-NOAC in face of the rapidly increasing NOAC usage. Knowledge on this ischaemic stroke entity will define clinical characteristics, identify preventable causes and inform resource allocation on the evaluation modalities, reperfusion strategies and forecast future burden of IS-NOAC.
Early outcome prediction after ischemic stroke (IS) is of great importance. Prognosis is usually based on clinical variables and neuroradiological findings while serum biomarkers may contribute to prognostic accuracy. Inflammatory biomarker Suppression of Tumorigenicity 2 (ST2) has been shown as promising in IMU outcome predicting. The relationship between ST2 serum values and IS severity is not fully clarified. The proposed hypothesis is that earlier releasing and higher ST2 serum concentrations will be associated with a worse IS outcome. In this prospective and observational study 20 patients with IS will be included and followed. The primary outcome is functional outcome according to the modified Ranking scale at 90 days. In case of hypothesis confirmation, theoretical contribution will be in a better understanding of pathophysiological changes in acute phase of IS, while the clinical purpose is to improve the prognostic procedure.
The purpose of this study is to evaluate the safety, tolerability, and preliminary efficacy of single injection of it-hMSC in patients with ischemic stroke in a multicenter, blind, randomized, placebo controlled trial
Acute ischemic stroke is the most common type of stroke, accounting for about 60%-80% of all stroke, with high incidence, high mortality, high disability rate, has become the first cause of death in China. At present, only ultra-early thrombolytic therapy, endovascular therapy and antiplatelet therapy have obtained evidence-based medical evidence in ischemic stroke treatment, but only thrombolytic therapy and endovascular therapy can improve the good prognosis of patients. Intravenous thrombolytic therapy within 4.5 hours after the onset of ischemic stroke symptoms has been shown to be effective, which is recommended in the guidelines. In most countries, alteplase (R-tPA) is the only drug approved for the treatment of acute ischemic stroke. Recombinant human TNK tissue-type plasminogen activator (rhTNK-tPA) is a modified recombinant tissue-type plasminogen activator, with no procoagulant effect and a longer half life. In recent years, there are some studies on the comparison of therapeutic effects of TNK-tPA and RT-PA in patients with acute ischemic stroke, and TNK shows promising especially for large artery occlussion. At present, there are few reports on the application of rhTNK-tPA in Chinese stroke patients. The aim of this study is to evaluate the efficacy and safety of rhTNK-tPA in Chinese patients with ischemic stroke in a prospective, multicenter registration study.
Stroke is the second leading cause of death and one of the main contributors to disability. Patients who survive the acute phase of ischemic stroke and those with transient ischemic attack (TIA) are at high risk of subsequent vascular events. Importantly, recurrent strokes are associated with a higher social and economic impact, higher case fatality, and worse clinical outcome than first-ever strokes. The burden of post-stroke complications, residual deficits, and inadequate medical and psychosocial care all contribute to long-term disability and reduced quality of life in these patients. The Department of Neurology of the Medical University Innsbruck undertook the STROKE-CARD trial (NCT02156778) between 2014 and 2018 with follow-up until 2019 to evaluate the efficacy of the Post-Stroke disease-management program STROKE-CARD care. After implementation of STROKE-CARD care, the investigators aim to document the quality of post-stroke care and compare outcome parameters to historical cohorts and the change over time. Furthermore the investigators aim to gain a large data-resource for future research of biomarkers, disease mechanisms, prognosis and imaging mechanisms for R&D.
Endovascular treatment（ET）is an effective therapy for acute ischemic stroke(AIS) with great vessel obstruction. However, acute complications such as high postoperative perfusion injury, hemorrhagic transformation and restenosis resulted in functional independence in only about 50% of patients 90 days after interventional surgery. Therefore, it is very important to protect the neurologic function after emergency endovascular treatment. The investigators' previous studies have shown that combined with intravenous thrombolytic therapy and remote postconditioning（RIPC）can significantly improve the neurological impairment and short-term and long-term prognosis in patients with acute stroke. In this multicenter, randomized controlled trial, the investigators assumed patients with acute ischemic stroke who had successfully revascularization after ET might benefit from RIPC as well. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after ET. The primary endpoint measure was the proportion of patients with a favorable recovery of nerve function deficient assessed by Modified Rankin Scale （mRS≤2） 90 days after surgery. Secondary endpoints included the following: (1) Symptom endpoints: Neurological intelligence and function scores, postoperative hemorrhagic transformation rate, etc. (2) Blood index test: postoperative inflammatory factors, neuron-specific enolase (NSE) and other indicators. (3) Imaging endpoints: MRI-FLAIR , TCD, etc.
