Filter by:Warfarin (Coumadin) is a prescribed "blood thinner" medication used to make the blood less thick in people with high risk of forming blood clots. Despite the various methods to monitor this drug, life-threatening bleeding is a common undesired effect and might result in patient death. Patients starting warfarin therapy may require several weeks or even months to reach the appropriate blood level of warfarin. This blind practice could place the patient at high risk. There are several demographic and clinical factors that significantly influence how much warfarin the patient needs to attain the desired response. Genes, which control hereditary traits, are also important. Now, the investigators know that by using the information encoded in patient's genes the investigators are able to individualize the therapy. Two genes are considered to be involved in warfarin response (CYP2C9 and VKORC1). This study proposes to ascertain what CYP2C9 and VKORC1 variants are present in warfarin-treated Puerto Rican patients. To this purpose, a novel physiogenomic array comprising 384 variants in 222 genes of cardio-metabolic relevance will be used so the investigators are able to determine the structure of the Puerto Rican population in terms of ancestral contributions and how the admixture may impact the prevalence of CYP2C9 and VKORC1 variants. Secondly, the investigators will assess the association of these variants to clinical responses in order to develop a better method of dose estimation. The expected result is the improvement of warfarin therapy in Puerto Ricans. The proposed study will fill a gap in the knowledge of warfarin pharmacogenetics, providing new information on the prevalence of CYP2C9 (metabolism) and VKORC1 (sensitivity) polymorphisms in Puerto Ricans as well as their role in the warfarin response variability observed in this admixed population.
The objective of this study is to compare the efficacy, safety of DU-176b 30mg or DU-176b 15mg versus enoxaparin sodium for the prevention of venous thromboembolism in patients after elective total hip arthroplasty.
The objective of this study is to assess the efficacy, safety and dose-response relationship of DU-176b compared with placebo for the prevention of venous thromboembolism in patients after elective total knee arthroplasty.
We propose an observational study to assess the ability of intensivists to evaluate for deep vein thrombosis using 2 point compression ultrasonography.
This is a multi-center study designed to evaluate the accuracy and precision of the INRatio® Prothrombin Time (PT) Monitoring System, utilizing the INRatio test strip newly designed for low sample volume and heparin insensitivity, when used by trained medical professionals for the quantitative determination of PT and International Normalized Ratio (INR) in fingerstick and venous whole blood from subjects on oral anticoagulation therapy (OAT). These results will be compared to those PT/INR results obtained on plasma from the same subjects as analyzed at a central laboratory with the Sysmex CA-560 System.
Deep vein thrombosis (DVT)is devastating disease which influencing the mortality and morbidity of patients at-risk like those undergoing orthopedic surgery. Recent publication suggested HMO-co-A reductase inhibitor (statin) may reduce the occurrence rate of venous thromboembolism in apparently healthy persons. The pleiotropic property of statin like antioxidant, antithrombotic, anti-inflammatory may have effect on the positive results. We are investigating whether rosuvastatin is associated with lower incidence of deep vein thrombosis (DVT) in patients undergoing total knee replacement arthroplasty(TKRA)who are at-high risk for developing DVT
Deep vein thrombosis is a common condition seen in the Emergency Department. Standard of care for diagnosis of DVT includes a combination of a clinical pre-test probability rule known as Well's criteria, D-dimer blood testing, and Radiology department ultrasound. The purpose of this study is to determine whether Emergency Physicians can safely rule out deep vein thrombosis using Well's criteria and D-dimer blood testing combined with Emergency department bedside ultrasound.
The objective of this study is to evaluate the safety of antiplatelet (APA)therapy continuation in patients undergoing lumbar spine surgery (laminectomy, discectomy and foraminotomy), and to gather evidence-based data regarding postoperative outcomes potentially related to APA management.
The investigators aimed to use pharmacogenetic information in clinical practise which may lead to rapid, efficient, and safe warfarin dosing in this observational prospective study. In this context, the investigators plan to develop an algorithm for estimating the appropriate warfarin dose that is based on both clinical and genetic data from the Turkish study population. This study is unique not only investigating clinical factors, demographic variables, CYP2C9, and VKORC1 gene variations which contribute to the variability among patients in dose requirements for warfarin but also including thrombogenic single nucleotide polymorphisms (SNP) in the same patient population. Thus, warfarin would be a good example by being the first cardiovascular drug for pharmacogenetic guided "personalized medicine" applications.
The blood thinner "tinzaparin" might increase survival in patients with colon cancer undergoing surgical resection. The investigators want to assess if a trial allocating patients to prolonged treatment with tinzaparin versus standard of care is feasible.
