Filter by:The aim of this study is to overcome the current limits of the scoring systems used to predict both the thrombotic (VTE) and hemorrhagic (BLD) risk for the patient. The main problem of these scoring systems is due to the high rigidity related to the score assigned at each risk item. The presence of an item assigns the full score for that item, without the possibility to moderate that item's score. The final class of risk, for the patient, is the sum of the scores of the selected items. The approach used for the assessment is based on the presence or absence of certain items that will be summed. Starting from scoring system currently used for VTE (PADUA, CAPRINI, KHORANA) and also for BLD (IMPROVE), we will integrate all common items in a single scoring system managed by risk management algorithms that can identify the different classes of risk.
Venous thromboembolism (VTE) is a common and potentially fatal disease. It is considered a chronic disease with a recurrence rate of 30% at 10 years. Reduce the risk of recurrence is a serious public health issue. For this it is necessary to identify patients at high risk of recurrence. However, until now, only 50% of recurrences are in the presence of known risk factors, suggesting that there are still yet unidentified risk factors. The assumption behind this project is that there are specifically associated genetic polymorphisms to the risk of VTE recurrence. The aim of our project is to identify these polymorphisms from genome-wide data MARTHA cohort. This cohort is composed of 1542 subjects from the Marseille region with at least one episode of VTE documented. Patients in the cohort MARTHA have all been genotyped for approximately 500,000 polymorphisms. The investigators want to achieve a case-control study nested in the cohort MARTHA. Subjects with recurrent VTE (the case) will be compared to subjects with only one episode of VTE (the controls). The allelic frequencies of polymorphisms previously genotyped 500,000 will be compared between cases and controls. The identification of these new genetic variants associated with VTE recurrence should allow us to improve the pathophysiological knowledge of the disease, reduce the frequency of episodes and focus research on new therapeutic approaches.
This is a phase II, pragmatic, prospective, randomized, double-blind, adaptive clinical trial examining the efficacy of statins and aspirin in the reduction of acute lung injury and venous thromboembolism in patients with fibrinolysis shutdown.
This study shall determine whether XAPPORT - a mobile device app based on different guidelines, the summary of product characteristics of rivaroxaban, and clinical facts and practice - provides adequate guidance to physicians attending patients undergoing elective surgery, who have to interrupt treatment with rivaroxaban for surgery, in deciding how to approach the pre- and postoperative management of anticoagulation.
This research focuses on the development and validation of indicators on the appropriateness of oral anticoagulant prescriptions. The investigators want to propose transferable tools to other healthcare institutions to allow automated construction of indicators as part of a structured approach to improve future practices. The main objective of the study is to develop indicators on the appropriateness of oral anticoagulant prescriptions in adult medicine automated from the hospital information system and to assess their criterion validity.
Low molecular weight heparins (LMWH) are the reference molecule for the long term treatment of venous thromboembolism (VTE) in cancer patients but remains, however, associated with a high risk of recurrent thromboembolism. The high rate of recurrence may result from alterations in the pharmacokinetics of LMWH. The primary purpose of the study is to compare the pharmacokinetics of anti-Xa activity in patients with cancer and patients without cancer treated with curative dose of low molecular weight heparins (LMWH) for venous thromboembolism (VTE). The secondary purposes are 1/ to study the correlation between anti-Xa LMWH and concentration of plasma heparanase and 2/ to evaluate the predictive nature of the anti-Xa activity on the occurrence of thromboembolic recurrence in cancer patients treated with LMWH for VTE.
The aim of this study estimate VTE incidence. Investigators prospectively record all cases of symptomatic pulmonary embolism (PE) and deep vein thrombosis (DVT) of the lower limbs diagnosed between March 1, 2013 and February 28, 2014 in hospitals and in the community.
REMMITE, a retrospective and prospective registry with one-year follow-up, will provide valuable insights into the clinical diagnosis, management, treatment trends as well as related outcomes of three cohorts: DVT, DVT-PE, PE patients throughout many regions of Mexico and through different health care systems.
The primary study goal is to improve the quality of care transitions for patients with new episodes of venous thromboembolism (VTE). Primary Outcomes: To measure differences in the quality of care transition, as measured by the Care Transition Measure (CTM)-15 in the investigators target population of patients with incident VTE randomized to either a multicomponent, anticoagulation medical home intervention or usual care. Secondary Major Outcomes: To measure the difference in recurrent VTE, major hemorrhage, all-cause re-admissions, and mortality between the investigators intervention and comparison groups at 30 and 90 days in the investigators target population. Secondary Other Outcomes: To measure patient knowledge, health-related quality of life, and time in the therapeutic range (TTR) for patients on warfarin in the investigators target population.
[18F]GP1 targets platelet GPIIb/IIIa receptor in thrombus. [18F]GP1 PET/CT imaging will noninvasively assess thrombus in whole body with good sensitivity with information of thrombus. Safety, pharmacokinetics, biodistribution, internal radiation dosimetry and diagnostic performance of [18F]GP1 will be assessed in all subjects.
