Filter by:The purpose of this study is to determine if certain seizure medications raise levels of cholesterol and other blood components which could increase the risk of heart attacks and strokes.
A wide variety of individuals are at risk for bleeding, but even though bleeding symptoms are common it is difficult to compare different people's symptoms. Recent research has found that carefully designed surveys can be used to calculate a bleeding score that is useful for diagnosing bleeding disorders, but normal individuals have not been specifically studied in large numbers with a comprehensive survey. Whether factors like race, ethnicity, age, sex, aspirin use, and previous trauma and surgery influence bleeding scores is also unknown. The primary goal of this study is to use a comprehensive computerized questionnaire to record the bleeding symptoms of normal individuals and then assess the range and severity of bleeding symptoms in this normal population. Secondary goals include determining whether race, ethnicity, age, sex, aspirin use, and previous trauma and surgery correlate with bleeding symptoms.
The purpose of this dose-ranging pilot study is to compare Recombinant Activated Factor VII, Prothrombin Complex Concentrate and Fresh Frozen Plasma (each starting at low doses with escalation if necessary) for the reversal of warfarin in the setting of acute intracranial hemorrhage.
The purpose of the study is to assess the coagulation changes that occur in patients undergoing elective Cesarean delivery using thromboelastography (TEG). We will compare coagulation data to assess potential coagulation changes associated with hemoglobin changes before and after surgery, and related to estimated blood loss.
The aim of the study is to compare the outcomes of trans-catheter arterial embolization (TAE) and surgery as salvage therapy of peptic ulcer bleeding after failed endoscopic therapy.
The study investigates safety, feasibility and effectiveness of cervical spinal cord stimulation (SCS) in prevention of cerebral arterial vasospasm following aneurysmal subarachnoid hemorrhage (aSAH). It is postulated that 2 week long stimulation of the cervical spinal cord using an implanted epidural electrode will prevent or decrease severity of cerebral arterial vasospasm following aSAH.
The study's objective is to evaluate the effectiveness and safety of tranexamic acid for adult patients with moderate to severe TBI.With the research question as "Does TXA reduce the incidence of progressive intracranial haemorrhage by 50% compared to placebo in moderate to severe adult TBI patients at Khon Kaen Hospital?"
The purpose of this study is to determine the effect of clopidogrel or aspirin reactivity as measured by a point-of-care platelet function assay on thrombotic or bleeding events after percutaneous coronary intervention (PCI) with drug eluting or bare metal stent. Methods: Platelet reactivity on clopidogrel and aspirin therapy is measured before PCI with VerifyNow (Accumetrics Inc.,San Diego, CA, USA) P2Y12 or aspirin assay respectively in 1000 consecutive patients from 20 centers in France undergoing coronary angioplasty with stent. Exclusion criteria are: Acute myocardial infarction, treatment with vitamin K antagonists and the use of antiGP2b3a before PCI. All patients are pre-treated with clopidogrel and aspirin. Non-response to aspirin or clopidogrel is determined according to the result of the VerifyNow assay (cut off : < 15 % for P2Y12 and > 550 ARU for aspirin). The primary end point is the occurrence of definite or probable stent thrombosis (ARC definition) and the secondary end-points include global and cardio-vascular mortality, non fatal myocardial infarction and major bleeding. A clinical evaluation is scheduled at discharge and by telephone contact at one month and one year.
The purpose of this study is to evaluate the superiority of effect of the modified micro-invasive aspiration and drainage and conservative medical therapy in the treatment of ICH spontaneously hypertensive scientifically.
There are few treatments for central fever (fever that is due to the central nervous system, as opposed to an infectious source). We hypothesize that an externally applied cooling blanket will reduce temperature in neurologically ill patients with central fever.
