Filter by:Stroke is a leading cause of physical and cognitive disabilities. The most common type of stroke is ischemic (lack of blood flow to the brain due to clot blocking a blood vessel). Many people with stroke (PwS) have changes on the brain imaging called small vessel disease (SVD). This is a condition that affects tiny blood vessels supplying the brain, leading to decreased blood flow in some parts of the brain. These brain changes may hamper the recovery process after stroke, or lead to recurrent stroke and cognitive impairment. SVD is a slow process that can be seen as multiple black spots on computed tomography or white spots on magnetic resonance imaging. Current treatments to reduce the effect of SVD on PwS are to control high blood pressure, high blood sugar, high cholesterol and increase physical activity. However, these approaches do not lead to a reduction in SVD. Remote Ischemic Conditioning is a type of treatment delivered with help of a regular blood pressure machine. This does not involve any drug. A typical treatment involves the application of a blood pressure cuff followed by brief sessions of compressions and relaxation on the arm muscles much akin to blood pressure measurement but for 5 min. It leads to a transient safe state of less blood flow in arm muscles which initiates the release of molecules and signals transmitted by blood. These signals may then go on to improve blood flow in the brain. Recent animal and human studies have suggested that the use of RIC may reduce the SVD load. A new device will be used to deliver remote ischemic conditioning therapy in a better manner. Existing devices generate the same amount of compression for all people. The pressure applied by the machine in the arm may be either more than required or less than required. The ideal compression would be one that achieves a low blood flow state in the arm at the least possible pressure. To achieve this our group is using a small light sensor to inform us. The light sensor is closely applied to the skin over the arm below the blood pressure cuff. It emits light that is absorbed by the skin and the light is then reflected. This is detected by other sensors placed together. From the reflected light the sensor can obtain information about blood flow in the skin. When the pressure increases with help of an automated machine the light sensor can detect that blood flow are reduced and this information is displayed on the computer. The information about skin blood flow will inform about the level of pressure to apply to give accurate treatment. The new device with optical feedback will deliver RIC in PwS and SVD in a safe and reliable manner. A total of 51 patients will take part in this study. Thirty-four will get remote ischemic conditioning therapy and 17 patients will get sham-control therapy. All patients will get standard post-stroke treatment according to the Canadian Stroke Best Practices Recommendation.
Normoxia Hyperoxia (NBO) is a neuroprotective approach that can be implemented early. NBO is simple and non-invasive and can be used at home or in an ambulance to ensure the shortest possible time after cerebral ischemia occurs. The previous study by the investigators suggested that NBO therapy in the early stage of cerebral ischemia has a neuroprotective effect on ischemic brain injury. Although the neuroprotective effect of NBO has been demonstrated, the optimal duration of treatment for NBO to exert neuroprotective effect is still unclear. Therefore, further discussion of the duration of NBO treatment will contribute to the clinical application of NBO and provide a definite theoretical basis for the treatment of cerebral infarction.
This is a phase II, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of multiple doses of LT3001 drug product in subjects with acute ischemic stroke (AIS)
Background: Stroke puts important economic and social loads on the society and was reported to be the most important reason for disability throughout the world. Purpose: The present study aims to experimentally examine the effect of aromatherapy and foot massage on happiness, sleep quality, and fatigue levels of patients with stroke. Material and method: The present study is a randomized clinical study with a control group. Participants were randomly divided into three groups (foot massage + aromatherapy, aromatherapy, and control). The study was carried out with 91 patients diagnosed with stroke. The data were collected using Sociodemographic Status Survey, Oxford Happiness Questionnaire, Piper Fatigue Scale, Pittsburgh Sleep Quality Index (PSQI). Statistical analyses were performed using SPSS (IBM SPSS Statistics 24) package program. The results were interpreted using frequency tables and descriptive statistics. Foot massage group was given 30min foot massage sessions (3 days per week) for 4 weeks, whereas foot massage + aromatherapy group was given lavender oil inhaler during the foot massage.
Rationale: Recently, two prospective multicenter RCT reported a potential beneficial effect of endovascular thrombectomy (EVT) in patients with an acute symptomatic basilar artery occlusion (BAO). However, the high rate of crossover in BEST study and the long-term of recruitment in BASICS study influenced the validity of the results. Objective: To assess the outcomes and prognostic factors of recanalization therapy in patients with BAO, caused by a CTA/MRA/DSA confirmed occlusion of the basilar artery. Study design: This is a prospective observational study. Study population: Patients with acute ischemic stroke and a confirmed basilar artery occlusion by CTA/MRA/DSA. Main study parameters/outcomes: Favorable outcome at day 90 defined as a modified Rankin Score (mRS - functional scale) of 0-3. The estimate will be adjusted for the known prognostic variables age, time from onset to treatment, stroke severity (NIHSS), PC ASPECT and collateral flow and adjusted and unadjusted estimates with corresponding 95% confidence intervals will be reported.
This study is designed to evaluate the safety, efficacy, and pharmacokinetics of balovaptan compared with placebo in participants with acute ischemic stroke (AIS) at risk of developing Malignant Cerebral Edema (MCE)
The objective of the study is to find out the in-hospital clinical outcomes among Chinese Acute Ischaemic Stroke (AIS) patients, who were treated with intravenous (IV) Recombinant Tissue Plasminogen Activator (rt-PA) within 4.5 hours of symptom onset in different age groups (18 to 80 years and above 80 years).
This is a randomized open-label, with blinded outcome pilot study to evaluate the effect on inflammatory laboratory values and explore clinical outcomes in patients who present with ischemic strokes due to large vessel occlusions and are treated with either current accepted management, or accepted management in addition to transcutaneous auricular vagal nerve stimulation.
A two stage phase 2 study with an interim analysis to provide evidence that subjects provided with early administration of NanO2 who are located at small rural spoke hospitals and identified with large vessel occlusion ischemic strokes as well as viable penumbra prior to transfer to larger hub hospitals and who continue dosing NanO2 until revascularization is achieved by intravenous alteplase and/or mechanical thrombectomy, will experience stroke recovery by shifting ischemic brain tissue to normal tissue pO2 environments.
The purpose of this study is to assess the safety and efficacy of the OsciPulse System in reducing serum d-dimer levels in hospitalized ischemic stroke patients.
