Filter by:1. To evaluate ocular blood perfusion status and the possibility of craniocerebral vascular lesions of patients with ocular ischemia syndrome (OIS) using arterial spin labeling (ASL) magnetic resonance imaging technique. 2. To evaluate the specificity, sensitivity and accuracy of arterial spin labeling (ASL) magnetic resonance imaging technique in OIS diagnosis, compared with the traditional routine examination method.
To compare prophylactic strategies of atrial fibrillation in patients with CAD and without AF.
Correction of the deficit in the perfusion pressure of the microcirculation that supplies the nerve by intravenous infusion of Prostaglandin E1 (PGE1) (Alprostadil), expected to improve visual function in patients with ischemic optic neuropathy previous non-arteritic (NOIANA).
The study is a single-arm, open-label, multicenter clinical trial.The primary purpose of this trial is to evaluate the incidence of symptomatic intracranial hemorrhage in patients with acute ischemic stroke within 48 hours after the use of Eptifibatide injection. Patients with acute ischemic stroke treated with intravascular thrombolytic therapy, mechanical thrombolysis, angioplasty and so on were treated with Eptifibatide injection on the first day, followed by the second day, the third day, the discharge day and the 90 days.
The purpose of this study is to investigate responses of pain and the maintenance of mechanical muscle hypersensitivity following an acute exercise-induced ischemic condition repeated over time in a prolonged NGF-sensitized muscle. Additionally, the influence of the pain modulating system on prolonged NGF muscle hypersensitivity caused by peripheral mechanisms and central mechanisms will also be investigated.
The present study is designed to investigate the short-term and long-term renoprotective role of pneumoperitoneum preconditioning in patients undergoing laparoscopic partial nephrectomy.
Protection of brain development is a major aim in the Neonatal Intensive Care Unit. Hypoxic-Ischemic Encephalopathy (HIE) occurs in 3-5 per 1000 births. Only 47% of neonates have normal outcomes. The neurodevelopmental consequences of brain injury for asphyxiated term infants include cerebral palsy, severe intellectual disabilities and also a number of minor behavioural and cognitive deficits. However, there are very few therapeutic strategies for the prevention or treatment of brain damage. The gold standard is hypothermic treatment but, according to the literature, melatonin potentially acts in synergy with hypothermia for neuroprotection and to improve neurologic outcomes. Melatonin appears to be a good candidate because of its different protective effects including reactive oxygen species scavenging, excitotoxic cascade blockade, modulation of neuroinflammatory pathways. The research study will evaluate the neuroprotective properties and the effects of Melatonin in association with therapeutic hypothermia for hypoxic ischemic encephalopathy.
The overall goal of this program of research is to develop and systematically evaluate an integrated smartphone and web-based intervention (at heart [formerly called HEARTPA♀N]) to provide evidence-informed symptom triage and self-management support to reduce pain and increase health-related quality of life (HRQoL) in women with heart disease. The investigators will use the individual and family self-management theory, mobile device functionality and the pervasive information architecture of mHealth interventions, and follow the sequential phased approach recommended by the Medical Research Council (MRC) to develop at heart (progressive WebApp). Funding was received from the Canadian Institutes of Health Research to develop the architecture and conduct usability testing (Phase 2, complete) to ensure it is easy to use, efficient and satisfying to operate. In Phase 3 (current proposal), feasibility in terms of implementation (accrual rates, acceptability and level of engagement) and initial estimation of effectiveness outcomes (estimates of magnitude of effect) will be evaluated in a pilot randomized controlled trial (RCT). The Phase 3 pilot study will enable the investigators to refine the prototype, inform the methodology, and calculate the sample size for a larger multi-site RCT (Phase 4, future work).
The study will investigate whether a new high resolution heart Magnetic Resonance Imaging scan, combining assessment of ischemia and viability by perfusion and Late Gadolinium Enhancement -Cardiac Magnetic Resonance is superior to Late Gadolinium Enhacement imaging alone in predicting functional recovery following revascularisation.
This is a pilot randomised control trial to assess the safety, compliance, and acceptability of delivering a 6-week programme of remote ischaemic conditioning (RIC) to stroke patients suffering with fatigue, and study feasibility. A minimum of 34 patients who have suffered an ischeamic or haemorrhagic stroke and who suffer from fatigue, will be recruited and randomised to receive a 6-week programme of either RIC or a sham intervention.
