Filter by:Utilisation of extended criteria donors due to critical organ shortage contributes to increased ischemia reperfusion injury as well as mortality following liver transplantation. Experimental data show protective effects on hepatic ischemia reperfusion injury (IRI) using the calcineurin inhibitor Tacrolimus applied intravenously or directly as a hepatic rinse. Moreover clinical data indicate a protective role of a Tacrolimus rinse in human liver transplantation when using normal, healthy grafts. The effects of Tacrolimus on hepatic injury in extended donor criteria (EDC) liver grafts remain unclear. Therefore, the aim of the present study is to examine the effects of a Tacrolimus ex vivo rinse (20 ng/ml) on cellular injury after transplantation of marginal liver grafts exhibiting 2 or more EDCs according to Eurotransplant's definition of EDC grafts.
To determine the revascularization rate, clinical efficacy and safety of the CE-marked MindFrame System in ischemic stroke patients
Approximately half of patients with acute chest pain, a very common reason for emergency department visits worldwide, have a cardiac cause. Two-thirds of patients with a cardiac cause are eventually diagnosed with a so-called non-ST-elevation myocardial infarction. The diagnosis of non-ST-elevation myocardial infarction is based on a combination of symptoms, electrocardiographic changes, and increased serum cardiac specific biomarkers (high-sensitive troponin T). Although being very sensitive of myocardial injury, increased high-sensitive troponin T levels are not specific for myocardial infarction. Invasive coronary angiography is still the reference standard for coronary imaging in suspected non-ST-elevation myocardial infarction. This study investigates whether non-invasive imaging early in the diagnostic process (computed tomography angiography (CTA) or cardiovascular magnetic resonance imaging (CMR)) can prevent unnecessary invasive coronary angiography. For this, patients will be randomly assigned to either one of three strategies: 1) routine clinical care and computed tomography angiography early in the diagnostic process, 2) routine clinical care and cardiovascular magnetic resonance imaging early in the diagnostic process, or 3) routine clinical care without non-invasive imaging early in the diagnostic process.
The purpose of this study is to determine if early ablation (i.e., ablation of ventricular tachycardia in patients with infrequent VT episodes) is more effective than medical therapy alone for the treatment of ischemic ventricular tachycardia in patients with Implantable Cardioverter Defibrillators (ICDs) who continue to have episodes of ventricular tachycardia despite drug therapy.
The primary objective of this study is to compare effectiveness of five different neuroprotectants, including butylphthalide, edaravone, citicoline, cerebrolysin, and piracetam, among patients with acute ischemic stroke. The secondary objectives of the study are as follows: - To compare safety of five different neuroprotectents, including butylphthalide, edaravone, citicoline, cerebrolysin, and piracetam, among patients with acute ischemic stroke. - To compare cost-effectiveness of five different neuroprotectents, including butylphthalide, edaravone, citicoline, cerebrolysin, and piracetam, among patients with acute ischemic stroke.
This is a prospective, randomized, placebo-controlled, double blind safety and feasibility clinical trial.
CACT-IHF aims to evaluate the clinical efficacy and safety of Qishen Yiqi Dripping Pills in treating ischemic heart failure. Meeting the diagnosis, inclusion and exclusion criteria, the study plans to recruit 640 cases from 35 upper class hospitals in China, who are divided into two groups (treatment and control group) by central randomization service. The treatment group will be administrated with one bag of Qishen Yiqi Dripping Pills (0.52g/bag) three times a day in addition to standardized western medications. Whereas the control group will be given one bag of Qishen Yiqi Dripping Pills dummy (0.52g/bag) three times a day in addition to standardized western medications. Efficacy indicators include primary indicator (6 minute walk test) and secondary indicators: composite endpoint consisting of all-cause death, emergency/re-admission to hospital due to HF, frequency of re-admission due to cardiovascular disease, acute coronary syndrome, severe arrhythmia, cardiac shock, revascularization, stroke, pulmonary embolism and peripheral vascular incidences, etc.; Brain Natriuretic Peptide; echocardiography; cardiothoracic ratio; NYHA cardiac function classification; Minnesota life quality scale; scores from the four traditional chinese medicine (TCM) diagnostic methods). Other indicators include blood cholesterol, triglyceride, high density cholesterol and low density cholesterol. Safety indicators include blood pressure, heart rate, blood and urine routine tests, liver and renal function tests, serum electrolytes, electrocardiogram and adverse events. All of the patients will receive interventional drug treatment for 6 months. Follow up is needed on the 1st, 3rd, 6th, 9th, 12th month after recruitment. All patients will be followed up until the end of study (Refers to the 12th month of the last case recruited into the study).
This registry is a clinical post-market evaluation of the Orsiro LESS in subjects requiring coronary revascularization with Drug Eluting Stents (DES).
Ventilator-associated pneumonia (VAP) is an important cause of morbidity and mortality in ventilated critically ill patients specially in intensive care unit (ICU). It is associated with an increased duration of mechanical ventilation, high death rates and increased healthcare costs in China. However, VAP is preventable and many practices have been demonstrated to reduce the incidence of this disease, but the morbidity is still so high. So much more methods of prevention should be needed to reduce the incidence of VAP. Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) present anti-inflammatory and immunomodulatory effects besides their ability to regulate cholesterol composition. So it is hypothesized that early use of statin may prevent some of the infection disease such as VAP. Actually, Two studies have showed that statin treatment is associated with reduced risk of pneumonia. However, the relationship between statins and reduced risk of pneumonia is not consistent. After reviewing some of the guidelines,meta analyses and system reviews, the investigator find that advanced age,immune suppression from disease or medication and specially depressed level of consciousness are the risk factors of VAP. So the investigator assumes that early use of statin may give us a favorable outcome in the patients with coma or in the patients with severe disease (Acute Physiology and Chronic Health Evaluation II score > 15 or Glasgow coma score < 7). In addition there is no prospective study to investigate the role of statins in VAP in the patients with ischemic stroke. The investigator hopes that this study can approve the relationship between statins and reduced risk of VAP in the patients with ischemic stroke. And it can improve the processes,outcomes and costs of critical care as well.
The purpose of this study is to evaluate whether intramuscular injections of NL003 into the calf is safe and effective in the treatment of critical limb ischemia
