Filter by:Non-surgical traumas to the lower limbs that require orthopedic immobilisation (plaster or splint) are a frequent reason for going to accident and emergency. Due to venous stasis caused by immobilisation, hypercoagulable states and vascular injuries brought on by the trauma, these patients are at risk of developing VTE. For this reason, it is current practice in France and Belgium for the majority of patients to receive a preventative anticoagulant treatment. However, the benefit of this treatment, which has a considerable cost, is controversial. Contrary to French recommendations, American recommendations from 2012 actually advise against systematic preventative medicine, with prevention appearing to be effective primarily in studies with restrictive inclusion criteria. The most significant randomised controlled study on the subject did not show the benefit of low-molecular-weight heparin (LMWH) on the rate of symptomatic VTE among 1,435 non-selected patients. Therefore, in 2017, the Cochrane meta-analysis concluded that stratification of the risk of thromboembolism is required. For this purpose, in collaboration with the Dutch team of Nemeth et al. we have recently developed a risk stratification model that takes into consideration the patient's characteristics, the type of immobilisation and the severity of the trauma: the TRiP(cast) score. This score is applied retrospectively to a large cohort and demonstrates excellent prognostic performances (AUC (area under the curve) of 0.74). In addition, when using a <7 limits, it makes it possible to identify a large group of patients at very low risk of developing VTE (negative predictive value: 99.2%). The aim of the CASTING study is to prospectively demonstrate the reliability and utility of the TRiP(cast) score by showing that patients with orthopaedic immobilisation of a lower limb who are not receiving preventative treatment on the basis of a TRiP(cast) score of <7 have a very low rate of symptomatic VTE, which allows for a significant reduction in prescriptions of anticoagulants in comparison with prior practices.
MACACOD is a clinical record in the usual clinical practice of direct oral anticoagulants (dabigatran, rivaroxaban, apixaban and edoxaban). Design: single-center, observational, prospective, uncontrolled study of anticoagulated patients with any direct oral anticoagulant (DOAC) with atrial fibrillation or venous thromboembolism to determine the incidence of serious complications (thromboembolic or hemorrhagic) in real life
Patients who have developed a venous thrombosis will receive apixaban to treat and prevent a secondary thromboembolism.
This study aims to investigate a novel positron emission tomography(PET)-probe for imaging of fresh intravascular blood clots in pulmonary embolism (PE) and deep venous thrombosis (DVT).
Post-surgical bleeding is a major source of morbidity in cancer patients, and ramifications can include need for transfusion, increased length of hospital stay, unexpected return to the operating room, or even death. Current guidelines support that all cancer patients who require surgical procedures receive post-operative blood thinners to minimize risk for blood clots in the legs or lungs, known as venous thromboembolism (VTE), but these medications have an unfavorable risk/benefit relationship among patients at low risk for VTE. The proposed work will pilot a randomized, double blind, placebo controlled trial to critically examine the role of de-implementation of current guidelines that mandate blood thinning medications among cancer patients at low risk for VTE who require surgical procedures; the pilot trial will allow optimization of the design of a future pragmatic multicenter trial, which ultimately would maximize patient safety after surgical procedures for cancer.
Participants between the ages of 19 and 70 who were initially diagnosed with venous thromboembolism and were accompanied by dyslipidemia (LDL> = 100 mg / dl) were enrolled. Participants diagnosed with pulmonary embolism, pulmonary embolism CT, and peripheral B-mode ultrasound (B-mode ultrasound) Only participants who do not meet the exclusion criteria should be enrolled in the study. Once the participant is selected, the patient is informed of the study and receives the consent form. Participants who are eligible for all of the criteria and who do not qualify as exclusion criteria should be enrolled in the study and randomly enrolled in a 1: 1 dose of rosuvastatin 20 mg once daily or equivalent. Participants who previously used statins have a wash-out period of two weeks or more Participants undergo a visit at 12 weeks after initiation of treatment. For fasting blood tests, patients visit on an empty stomach. Outpatient follow-up observes side effects after last visit and observes changes in vital signs and weight. After 24 weeks of treatment, the participant visits for efficacy evaluation. We performed body weight, vital signs and blood tests (WBC, hemoglobin, BUN, creatinine, CRP, D-dimer, fibrinogen, PAI-1, AST, ALT, CK, total cholesterol, triglyceride, HDL and LDL). 1. Primary evaluation item: Improvement of venous insufficiency at 6 months 2. Secondary evaluation items: Improvement of blood lipid concentration, inflammation and blood clotting at 6 months Comparison of numerical rate of change 3. Tertiary evaluation items: recurrence of venous thrombosis
Venous thromboembolism (VTE) is a common and potentially fatal pathology in France. The risk of recurrence is around 5 to 7% per year. The identification of patients at risk of VTE and its prevention is a real health issue in particular. 50% of MTEV recurrences occur in the absence of a risk situation, suggesting the involvement of specific risk factors for MTEV recurrence that have not been identified to date. In the last ten years, so-called "genome-whole" or "genome wide" association (GWAS) approaches have identified new genetic risk factors for the first episode of VTE. On the other hand, no study has focused on the predictive factors of recurrence. The previous project, conducted from 2012 (NCT02904967), had as its main objective to identify new genes for susceptibility to MTEV recurrence by comparing cases of MTEV recurrence versus controls having had a single episode of MTEV. The MARTHA cohort (1,542 patients) is extremely valuable study material and is one of the few cohorts in the world with genome-wide data in the field of VTE. Follow-up could only be performed in 359 patients, 76 (21%) of whom presented with a new episode of VTE. The objective of this project is to increase the number of patients for whom the investigators will have information on recurrence / non-recurrence of VTE, by querying national registries on the vital status of patients, and possible causes of death. . These new data on the occurrence or not of a new thrombotic episode, will be confronted with the genetic data already available in all the patients in order to identify specific genetic risk factors and potentially predictive of the recurrence of MTEV.
Anticoagulants are used to prevent thrombotic events in patients with predisposing factors. However, the use of such therapies is associated with bleeding complications, which can be a serious safety issue. Thus, it is important to evaluate the safety and effectiveness of such therapies based on data collected in clinical practice in order to generate relevant scientific data that could be used to support clinical and regulatory decisions. This is an open, prospective, multicenter, observational cohort study that aims to prospectively record the clinical history of adult patients receiving anticoagulant treatment, irrespectively of the prescribed drug and the indication for its use.
Patients with cancer are at a significantly increased risk of experiencing a venous thromboembolism (VTE). VTE is defined by a blood clot in the leg or lower extremity (deep vein thrombosis) or a blood clot in the lung (pulmonary embolism) and is a leading cause of condition of being diseased and death among cancer patients. The goal of the study is to gather information how often venous thromboembolism (VTE) occurs in prostate cancer patients in Sweden and how this condition is treated with blood thinners.
