Filter by:One of the most devastating complications of coronary artery bypass surgery (CABG) is postoperative stroke. While there are multiple causes of stroke after CABG, particles generated during handling of the aorta is believed to account for most neurologic effects. Handling of the aorta during CABG occurs several times during the operation. One strategy to reduce aortic handling is to avoid cardiopulmonary bypass altogether by using off-pump techniques (OPCAB). Another method is to avoid the use of aortic clamps and/or to use devices that do not require aortic clamping. This study will test the hypothesis that an off-pump (OPCAB) approach and devices to perform clampless surgery will result in the least amount of aortic handling and therefore the lowest incidence and frequency of neurologic adverse events.
A multi-centric initiative to study safety,feasibility and efficacy of using intravenous autologous bone marrow mononuclear cells(BMMC) in patients with acute ischemic stroke.This phase of study is visualised as phase 2 study and will aim to determine dose response gradient of stem cell therapy and to explore if there is favorable risk to benefit ratio for autologous stem cell therapy in patient with acute ischamic stroke.
Previous research that utilises single sessions of transcranial direct current stimulation (tDCS) have demonstrated functional improvements. However these improvements are usually short-lived, lasting less than one hour before the patient's performance returns to baseline. In these studies, tDCS is typically applied with the goal of adaptively enhancing functional activation of pathologically under-active tissue or suppressing pathologically over-active tissue. Interestingly, a small body of evidence is now emerging to indicate that tDCS can improve learning/memory functions in healthy controls. The goal of this study is to test if the application of tDCS could enhance learning and/or memory for physiotherapy rehabilitation, which may in turn lead to correspondingly greater motor improvement. Patients at a subacute stage (1 to 6 month post stroke) will attend for 10 consecutive daily sessions of tDCS. This research has important implications; previous studies suggest that such an approach has the potential to facilitate physical rehabilitation post-stroke and establish tDCS as a clinically viable rehabilitative tool. Recovery of motor skills may take many months to acquire and therefore strategies that have the potential to enhance acquisition of skill are of practical and scientific interest.
This pilot study examined the effect of task-oriented mobility training in three persons chronic post-stroke using a novel, wearable, mobile intention-based robotic orthosis (Tibion Bionic Leg).
ASCOT-10 is a follow-up study of surviving participants in the United Kingdom (UK)arm of the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT) which was conducted between 2000 and 2005.ASCOT's results showed substantial cardiovascular benefit from: 1) the use of a cholesterol lowering drug (atorvastatin) compared to placebo, and 2) the use of a blood-pressure lowering strategy based on amlodipine when compared to a strategy based on atenolol. ASCOT-10 will test the hypothesis that the ASCOT subjects who originally received Atorvastatin and those who received amlodipine based treatment will continue to show a cardiovascular benefit relative to those who did not, even though all the subjects have had access to optimal treatment in the interim.
Getting to the hospital quickly is the key to treating stroke. African Americans suffer more strokes with worse outcomes and receive stroke treatments less often than European Americans. This project will work to reduce these health disparities by creating and testing the feasibility of a peer-led faith-based behavioral intervention in an African American community with a goal to increase calls to 911 so stroke patients can be treated quickly.
The SURPRISE study investigates atrial fibrillation(AFIB) in patients with a previous unexplained stroke. It uses long term monitoring of the heart of up to three years, searching for paroxysmal atrial fibrillation(PAF) otherwise undetected in this population.
Stroke is among the most disabilitating diseases worldwide in terms of numbers affected and its consequences. A relatively new and well documented treatment of acute ischemic stroke today is tPA (tissue plasminogen activator; will be called thrombolysis from now on) Unfortunately only a minority of patients is given this treatment. The large randomised controlled trials that investigated the safety and efficacy of thrombolytic therapy in treatment of acute stroke did not include patients over 80 years. In an aging population in the western world it will be of importance to investigate whether this treatment is safe and effective in this group. Both Sorlandet hospital Kristiansand Norway and Bergen hospital have administered thrombolysis to selected patients over 80 years the last years. In addition there has been a registration of patients in stroke registers at both locations. This lays a foundation for further investigation. In association with Bergen the investigators have included 77 patients over 80 years treated with thrombolysis. In addition the investigators have 85 patients treated with tpa below 80 years. In our cohort the investigators are going to compare outcome in the 2 groups. In addition the investigators are going to perform a regression analysis of selected variables to see if there is an association of those variables with predefined outcome measures. Our outcome measures is as follows: mRS=6 (death)and mRS 0-1(good outcome) on 3 months control. The third outcome measure will be developement of sICH secondary to tPA treatment. As definition of sICH we have chosen the same definition as Ecass.
Despite the abundance of stroke education materials available, studies continue to reveal severe deficiencies in stroke literacy (knowledge of symptoms, urgent action, and prevention measures). Expensive mass media stroke education campaigns are not sustainable for this purpose, particularly in economically disadvantaged populations. Instead, the investigators propose to intervene in school classrooms with children aged 9 to 11 years, to teach the five cardinal stroke symptoms, the correct course of action when they occur, and to highlight the potential therapeutic benefit of early hospital arrival, with the intent that the children will then educate their parents. To help accomplish this, the investigators have developed a program called Hip Hop Stroke (HHS), which is comprised of rap songs and two animated musical cartoons that incorporate stroke knowledge.
The purpose of this study is to evaluate the utility of the S-STREAM as an instrument to assess motor function in subjects who have experienced a nonhemorrhagic ischemic stroke.
