Filter by:A multicentre, randomised controlled Trial of Exenatide versus standard care in Acute Ischemic Stroke
A registry of consecutive patients who were admitted and diagnosed with acute myocardial infarction or acute cerebral infarction were conducted at the Guangdong General Hospital or the First Affiliated Hospital of Guangzhou University of Chinese Medicine, Yue Bei People's Hospital, China, between January 2000 and December 2016. The adverse clinical outcomes, including all-cause mortality, were followed from the date of admission for acute myocardial infarction or acute cerebral infarction until study end (December 31, 2016). All-cause mortality, including the date of death, was identified from the electronic hospitalization data, phone follow-up, and confirmed by the household registration (HUKOU) system, a record of registration required by law in China. Baseline characteristics, including major treatment of acute myocardial infarction or acute cerebral infarction, estimated glomerular filtration rate (eGFR) and proteinuria, were collected. Demographic data were determined from the electronic hospitalization data and electronic hospital discharge records. All comorbid conditions were identified using International Statistical Classification of Diseases, Tenth Revision (ICD-10), coding algorithms applied to electronic physician claims and electronic hospital discharge records. Life style (smoking), treatment regimen at discharge, including angiotensin-converting enzyme inhibitor (ACEI), angiotensin II receptor blocker (ARB), were determined from the electronic hospitalization data.
Scalp acupuncture formed by combining traditional Chinese acupuncture techniques and modern theories in medical anatomy has been widely used to treat ischemic stroke in China, but effective clinical trials that verify its efficacy are lacking. This study proposes to verify the effects of Lu's scalp acupuncture on ischemic stroke by comparing differential improvement of motor function between conventional rehabilitation alone and conventional rehabilitation with Lu's scalp acupuncture.
This study is designed to determine the safety, pharmacokinetics and pharmacodynamics of a single intravenous dose of TS23 in healthy adults.
The main purpose of this trial is to determine whether Xingnaojing, intravenously administered within 24 hours of symptom onset, improves the 3-month outcome in participants with acute ischemic stroke.
Stroke affects over 125,000 people each year in the UK and leaves at least 50% disabled. Treatment of stroke caused by a blockage in a blood vessel (ischaemic stroke), with clotbusting drugs improves the chances of good recovery, but must be given within 4.5 hours of onset. Currently only a small proportion of patients who arrive in hospital within 4.5 hours are treated. This is largely due to uncertainty about diagnosis and concerns about risk of bleeding associated with clotbusting medication. Patients with mild or improving symptoms in particular are often not treated because of uncertainty about relative risks and benefits. However, around one third of these patients go on to be significantly disabled. Routine CT scanning often does not show abnormalities in acute stroke (which take hours to become easily visible), and cannot show the extent or severity of blood flow changes in ischemic stroke. We wish to investigate the value of additional CT scanning that gives information on the blood vessels (angiography, CTA) and blood flow to the brain (perfusion, CTP) by undertaking a randomised trial. Extra scans are done in the same scanner and involve some extra radiation, injections of a contrast dye, and some extra time to acquire process and interpret. The extra scans may allow better treatment decisions for patients by increasing diagnostic certainty and by better assessment of stroke severity. However, we do not know whether the potential gains from better selection justify the resources and potential treatment delays that are involved. We will investigate whether the proportion of patients given clotbusting drugs differs between the two scanning protocols; and whether the outcomes differ, using standard measures of disability. We will also investigate whether use of different scanner manufacturers' software affect interpretation of scans.
Anticoagulants are generally recognized as a necessary therapy to prevent the recurrence of ischemic stroke in patients with non-valvular atrial fibrillation (NVAF), but in some patients they also cause bleedings, particularly intracranial hemorrhage. One of the independent predictors of intracerebral hemorrhage is the presence of cerebral microbleeds (CMBs); a high incidence of intracerebral hemorrhage is reported in patients with multiple CMBs. Recent study suggested that patients who had CMBs at baseline developed more new CMBs after 2 years (26%), compared with patients (12%) who did not have CMBs at baseline. However, there has been no study on the progression of CMBs in patients receiving so-called novel oral anticoagulants (NOACs). This study tests the hypothesis that the incidence of hemorrhagic stroke is lower in patients receiving NOACs (dabigatran, rivaroxaban, apixaban, and edoxaban) than in those receiving warfarin, and this difference reflects the difference in the effects of warfarin and NOACs on the progression of CMBs. Towards this goal, we enroll 200 patients with at least one CMB detected by 1.5 T MRI (T2*WI) at baseline, who treated with NOACs or warfarin for 12 months. Primary endpoint is the proportion of subjects with an increased number of CMBs at Month 12 of treatment with NOACs or warfarin. If the results of this study support the efficacy of NOACs in preventing increase of CMBs, this would be of great interest to domestic and overseas clinicians, in view of the potential therapeutic impact, including that for primary prevention of ischemic stroke.
Cerebral infarction is the most common form of stroke (80% of strokes). Stroke is the first cause of acquired disability, and the 2nd cause of dementia and death. The only approved treatment in the first 4.5 hour is intravenous rt-PA thrombolysis (Actilyse ®) whose objective is recanalization of occluded artery and reperfusion of the brain parenchyma. Few patients are treated (1-5%) and they keep disability in 50-60% of cases. This handicap is mainly correlated to the final infarct size. The objective of neuroprotective treatments is to reduce the final size of the cerebral infarction. The per-conditioning remote ischemic (Per-CID) showed a neuroprotective effect in cerebral ischemia by reducing the final size of cerebral infarction animal models. The per-CID corresponds, in cases of cerebral ischemia, to iterative ischemia realization of a member with a cuff. In humans, the per-CID has shown a cardioprotective effect in a randomized control trial involving 250 patients within 6 first hours of myocardial infarction and candidate for primary angioplasty.
Patients with brain hemorrhage resulting from a ruptured aneurysm (SAH) are at risk of developing a condition called vasospasm, one or two weeks after their hemorrhage. This is a major cause of stroke and death following SAH. A special type of CT scan, called CT perfusion, analyzes regional blood flow in the brain. We hypothesize that CT perfusion scans performed on admission and day 6 post-hemorrhage will enable us to predict which patients will go on to develop vasospasm.
Non-fasting triglyceride levels are thought to play a role in stroke. The investigators hypothesise that the results of a standardised oral triglyceride tolerance test in the subacute setting (3-7 days) after the first ischaemic stroke are associated with the risk of recurrent stroke within 12 months after the index event.
