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 analyze the association between aspirin efficacy and general platelet reactivity in relation to microembolic signals (MES) during carotid endarterectomy (CEA).
In patients who have suffered an ischemic stroke or TIA (mini-stroke), as well as in patients who are candidates for neuroendovascular stenting, it is standard of care to treat these patients with antiplatelet therapy, or "blood-thinners", the most common of which is clopidogrel (Plavix) with or without the addition of aspirin. A relatively common problem encountered with these patients is non-responsiveness to clopidogrel therapy. A prior study in cardiac patients showed that the addition of omega-3 polyunsaturated fatty acids (Lovaza, or "fish oil") can increase a patient's response to therapy with clopidogrel, but there have been no studies in neuro patients. In this study, patients will be divided into one of two groups: in the study arm, patients will receive clopidogrel +/- aspirin as well as Lovaza. In the control arm, patients will only receive clopidogrel +/- aspirin. Assays will be done to measure responsiveness to clopdiogrel on days 0, 12-24 hours after loading dose, day 3-5 if still inpatient, and at a follow-up visit 20-30 days after the start of the study. The investigators believe that this study will show an increase in platelet aggregation in patients receiving both clopidogrel and Lovaza.
This study is a prospective trial wherein each included subject will receive the experimental magnetically enhanced diffusion therapy. It will be conducted on a maximum of ten adult male or female patients who meet the inclusion and exclusion criteria and informed consent has been obtained. Subjects presenting in the emergency department with acute ischemic stroke and are eligible for tPA therapy may be considered for inclusion in the study.
The purpose of this study is to make a cohort event monitoring to see whether and how Shuxuetong injection in hospital results in adverse events or adverse drug reactions.
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.
Patients presenting to the emergency department with acute ischaemic stroke, who are eligible for standard intravenous tPA therapy within 4.5 hours of stroke onset will be assessed for "dual target" major vessel occlusion and mismatch to determine their eligibility for randomisation into the trial. If the patient gives informed consent they will be randomised 50:50 using central computerised allocation to intra-arterial clot retrieval after IV tPA or IV tPA alone. The trial is prospective, randomised, open-label, blinded endpoint (PROBE) design.
The investigators expect to find higher levels of both classical and minor antiphospholipid (APL) antibodies among the stroke cases. Furthermore, the investigators expect to find not only classical APLA but also minor antibodies. The investigators believe that minor antibodies have a major role in the hypercoagulability state.
Randomized controlled clinical trial to estimate overall treatment benefit (improvement in disability) among stroke patients treated with rt-PA who are randomized to also receive either low-dose Argatroban, high-dose Argatroban or neither.
