Stroke Recovery and Music or No Music

Start date: July 21, 2017
Phase: N/A
Study type: Interventional

The primary outcome of this study is to determine the quantitative increase in connectivity, as measured by fMRI brain and calculated as a percent increase from baseline in patients with ischemic stroke. Eligible patients will receive a listening session of music or spoken word listening, 30 days to 5 years following ischemic stroke. Assessments will include modified Rankin Scale, National Institute of Health Stroke Scale, functional Magnetic Resonance Imaging, motor function tests, and neuropsychological evaluations. Assessments occur at baseline, day 45, and day 90 after starting listening sessions.

Neurodevelopmental Therapy-Bobath Approach in The Early Term of Stroke; Safe and Effective

Start date: May 1, 2018
Phase: N/A
Study type: Interventional

Early term rehabilitation initiated after stroke should be based on motor learning principles and neural plasticity. To achieve motor learning and neural plasticity, exercises consisting of intense and repetitive training should be given according to the patients' functional level. The neurodevelopmental treatment-Bobath (NDT_B) approach is based on motor learning principles. In literature, studies that show the early term effects of NDT-B on functional recovery are inadequate. The aim of this study was to investigate the effects NDT-B applied in the early term of stroke, on postural control, functional movement, balance and activities of daily living.

NCT ID: NCT03596502 Active, not recruiting - Atrial Fibrillation Clinical Trials

Direct Oral Anticoagulants in Patients With Atrial Fibrillation (DOACs vs Warfarin)

Start date: February 1, 2018
Phase:
Study type: Observational

The purpose of this study is to assess safety and effectiveness of direct oral anticoagulants (DOACs) and warfarin for stroke prevention in patients with non-valvular atrial fibrillation (AF). The comparison of DOACs versus oral vitamin K antagonists, in particular warfarin, is of interest. The investigators will carry out separate population-based, matched cohort studies, using health administrative databases in seven Canadian provinces. New users of oral anticoagulants (DOACs or warfarin) for stroke prevention in non-valvular AF will be eligible to enter the cohorts. Follow-up will continue until a hospitalization or emergency department visit for a stroke. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the safety and effectiveness of the different anticoagulation regimens in stroke prevention in AF. We hypothesize that DOACs and warfarin will have similar safety and effectiveness profiles.

NCT ID: NCT03588572 Not yet recruiting - Ischemic Stroke Clinical Trials

The Effect of Venlafaxine on Language Function in Patients With Subcortical Aphasia: A fMRI Study

Start date: August 1, 2018
Phase: N/A
Study type: Interventional

Previous studies have demonstrated that venlafaxine significantly improves the language function of healthy subjects and increase of fMRI activation in cortical language area. This study was designed to investigate the relationship between venlafaxine on the cortical language functional reorganization and clinical language improvements in the stroke patients with subcortical aphasia. It is a randomized, controlled, single-blind, longitudinal trial which has approved by the ethics committee of Guangzhou General Hospital of Guangzhou Military Command, and all patients and their guardian should sign an informed consent. The patients will divide into the venlafaxine group and the control group according to the principle of randomization (random number table). The patients in the venlafaxine group begin to take a venlafaxine hydrochloride capsule after enrollment ( each containing venlafaxine 75mg), qd, until 4 weeks after randomization, and the control group do not. Assessments of language functional behavior and examines of functional magnetic resonance imaging (fMRI) should be performed on the first days (V1), 28±3 days (V2) and 90±3 days (V3) after randomization. Through all this procession, we expect improve the language function of participants in experiment and clarify its mechanism,the research may help develop a new treatment for other patients with similar conditions.

NCT ID: NCT03585595 Not yet recruiting - Ischemic Stroke Clinical Trials

Intensive Blood Pressure Intervention in Stroke (IBIS) Trial

IBIS
Start date: July 2019
Phase: Phase 3
Study type: Interventional

The investigators propose to conduct a multicenter randomized controlled trial to test the effect of a systolic blood pressure target of less than 120 mmHg (intensive treatment) compared to a target of less than 140 mmHg (standard treatment) on the risk of total recurrent stroke (ischemic and hemorrhagic) among patients with a recent ischemic stroke. The study findings will help in the development of clinical guidelines for blood pressure management among patients with ischemic stroke and will have an important global impact on reducing stroke-related morbidity and mortality.

Phase: N/A
Study type: Interventional

In order to bridge the great gaps, Chinese Stroke Association (CSA) and American Heart Association (AHA) sought to develop, conduct, and assess a multifaceted quality improvement intervention to increase the adherent rate of IV tPA and ET and improve 3-month clinical outcomes for these patients through our cluster-randomized stepped-wedge IMPROVE: Stroke in China trial.

NCT ID: NCT03577093 Recruiting - Ischemic Stroke Clinical Trials

Molecular Mechanisms of microRNA-494 Involving in Cerebral Ischemia

Start date: June 6, 2018
Phase:
Study type: Observational

We and other investigations suggested that the activation of nerve cell cycle following cerebral ischemia led to neuronal apoptosis, glial cell proliferation and the formation of glial scar.The cyclin-dependent kinases (CDKs) and cyclins jointly promoted the cell cycle progression. Our preliminary clinical trial found a new microRNA-miR-494, which involved in the occurrence of acute ischemic stroke. In our animal experiment, miR-494 could relieve cerebral ischemia injury through inhibiting cyclin-dependent kinase 6(CDK6), ubiquitin-conjugating enzyme E2L6 (UBE2L6) and histone deacetylase 3 (HDAC3), which suggested that miR-494 might play an important role in the regulation of cell cycle following cerebral ischemia. This project intends to verify the following hypothesis:①miR-494 suppresses CDK6, and/or fibroblast growth factor16(FGF16)-Ras-extracellular signal-regulated kinase(ERK)--v-myc avian myelocytomatosis viral oncogene homolog(MYC) pathway, and/or phosphatase and tensin homolog(PTEN)-/protein kinase B(AKT)-mechanistic target of rapamycin(mTOR)-S6k pathway;②miR-494 inhibits UBE2L6, upregulates the hypoxia-inducible factor 1 α(HIF-1α) expression in nerve cells, thereby increases the p21 and p27 protein levels and inhibits cyclin-dependent kinase2(CDK2)activity;③miR-494 represses HDAC3 and downregulates the cyclin-dependent kinase1(CDK1)protein level. These all mediate the cell cycle arrest of neurons and astrocytes, reduce the neuronal apoptosis and glial scar formation,promote the recovery of neurological function and provide new targets for the treatment of ischemic stroke.

The Impact of Anti-thrombosis on Cerebral Microbleeds and Intracranial Hemorrhage in Ischemic Stroke Patients

Start date: August 2018
Phase:
Study type: Observational

The purpose of this prospective cohort study is to investigate whether antithrombotic therapy in the secondary prevention of ischemic stroke increases the risk of the emerging CMBs and whether the change is associated with an increased risk of intracranial hemorrhage, providing an imaging evidence for individualized antithrombotic therapy in such patients.

NCT ID: NCT03568916 Completed - Atrial Fibrillation Clinical Trials

Direct Oral Anticoagulants in Patients With Atrial Fibrillation (DOACs vs DOACs)

Start date: November 2016
Phase:
Study type: Observational

The purpose of this study is to assess safety and effectiveness of direct oral anticoagulants (DOACs) for stroke prevention in patients with non-valvular atrial fibrillation (AF). The comparison of DOACs between themselves is of interest. The investigators will carry out separate population-based, matched cohort studies, using health administrative databases in nine jurisdictions in Canada, the UK and the US. New users of DOACs for stroke prevention in non-valvular AF will be eligible to enter the cohorts. Follow-up will continue until a hospitalization or emergency department visit for a stroke. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the safety and effectiveness of the different anticoagulation regimens in stroke prevention in AF. The investigators hypothesize that different DOACs will have similar safety and effectiveness profiles.
