Active clinical trials for "Venous Thromboembolism"

Given the risks associated with direct oral anticoagulants (DOACs) and the lack of defined pathways for patients prescribed this class of medications, the study intervention has the potential for an enormous impact in preventing medication errors and improving the quality of care transition, patient knowledge, and adherence with DOAC therapy.

Patients with genitourinary cancers (ex: bladder, testicular, kidney) are at high risk of developing blood clots if they receive systemic therapy (ex: chemotherapy, immunotherapy). Blood clots cause pain, may require hospitalization and invasive testing, and in some cases cause death. In fact, blood clots are one of the leading causes of death in patients with cancer. Furthermore, patients who develop a blood clot require medication to thin the blood for a prolonged (sometimes indefinite) period of time, and this can disrupt other important cancer treatments. Studies have shown that using low dose blood thinners to prevent blood clots during systemic therapy is effective in some patients with cancer. However very few patients in these studies had genitourinary cancers, therefore physicians in Canada are not sure if recommending blood thinners to patients with genitourinary cancers is useful or safe. Safety is a primary concern because blood thinners may cause bleeding, and patients with genitourinary cancers may have higher risk of bleeding than patients with other types of cancer. The investigators hypothesize that blood thinners are effective and safe for reducing blood clots in patients with genitourinary cancers. The objective of this study is to determine if a large clinical trial testing the effectiveness and safety of low dose blood thinners for preventing blood clots in patients with genitourinary cancers receiving systemic therapy is feasible.

The aim of this study is to examine the effect of the sock to be developed with wearable technology for patients who will undergo TUR surgery on the development of hypothermia and VTE. The population of the study will consist of patients who will undergo TUR surgery between 01 October 2023 and 01 October 2024. patients will be included in the study. The study was planned as a prospective, two-arm (1:1), randomised controlled, double-blind clinical trial. The data will be collected with the "Descriptive Characteristics Form" and "Hypothermia Monitoring Form". The hypothermia follow-up form includes "Shivering Level Diagnosis Form" and "Temperature Comfort Perception Scale" The descriptive variables of the patients included in the study will be expressed as mean ± standard deviation and median (maximum-minimum), percentage and frequency. In data analysis; dependent and independent t test will be used when parametric test preconditions are met. Changes in body temperature measurements obtained after wearing socks to be developed with wearable technology, repeated measurements, analysis of variance (Repeated ANOVA) if parametric, Friedman test if non-parametric, and post-hoc test will be used in intra-group multiple comparison analyses as further analysis. Post hoc power analysis will be performed after the sample size reaches 70.

Aim to determine if aspirin 81 mg orally twice daily is effective and safe as an extended VTE chemoprophylaxis agent after major abdominal surgery for IBD patients. Study will perform an open label trial of aspirin for VTE prophylaxis compared standard of care.

Venous thromboembolism (VTE) causes up to 100,000 deaths annually. Between 10%-30% of patients die within one month of VTE diagnosis, while survivors remain at increased risk for VTE recurrence or other complications like post-thrombotic syndrome or chronic pulmonary hypertension in the following decade. Trauma patients have many risk factors that predispose them to a VTE. During the first 48 hours after blunt trauma, patients are prothrombotic due to the release of procoagulant factors, have excessive thrombin generation due to extensive tissue and vascular injury, and have reduced circulation of endogenous anticoagulants like protein C.

Endovenous interventions are keyhole operations for varicose veins that are carried out from within the vein itself. Varicose veins are enlarged veins close to the surface of the skin. They are connected to the bigger deeper veins in the leg (known as deep veins). Because of this, operations to close the varicose veins can increase the chance of a blood clot forming in the deep veins. Blood clots in the deep veins happen in around 1 in 50 people after endovenous operations. A clot in the leg can cause swelling, pain, and other long-term problems. If a clot in the leg breaks off and travels to the lungs, it can cause problems with the lung' ability to move oxygen from the air into the blood and may, in rare cases, be life threatening. Varicose vein procedures may carry a slightly higher risk of blood clot formation, and we are currently unsure if current clot reducing medicines are beneficial in preventing blood clots in people having varicose vein procedures. This study will investigate if it is worthwhile prescribing medicines to reduce blood clots after varicose vein procedures.

Ongoing registration of patients with venous thromboembolism treated by means of antithrombotic therapy, thrombolisys, open surgery, endovenous desobstruction and stenting.

The purpose of this study is to identify risk factors of cancer-associated venous thrombosis and develop a prediction model to assist clinicians in tailoring anticoagulant therapy.

Venous thromboembolism (VTE) is a common disease with an incidence of 1-2/1000 persons per year. VTE is a chronic disease with a considerable risk of recurrence. Patients with unprovoked VTE, i.e. VTE in the absence of a temporary risk factor including surgery, cancer or immobilisation, have a high recurrence risk and indefinite anticoagulation is generally recommended. The recurrence risk of patients with VTE provoked by a transient risk factor is regarded as low. Discontinuation of anticoagulation after three months is recommended because the benefit of reducing the recurrence risk further by prolonged anticoagulation is outweighed by the bleeding risk. However, the newer direct oral anticoagulants are potentially associated with a lower bleeding risk than vitamin K antagonists. Because they are also meanwhile widely available and are convenient there is a trend towards prolonging anticoagulation also in patients with a VTE after a transient provoking factor. However, the definition of transient provoking factors is imprecise and a distinct categorization according to the risk of recurrence is lacking. Preliminary evidence suggests that the recurrence risk varies considerably between the different transient provoking factors. In a prospective cohort study, the investigators will include patients with a deep vein thrombosis or pulmonary embolism provoked by a transient risk factor defined according to Guidance of the Scientific and Standardization Committee of the International Society on Thrombosis and Haemostasis (Kearon et al., J Thromb Haemost 2016; 14: 1480-3) after discontinuation of anticoagulation. The study endpoint is recurrent symptomatic VTE.

This observational study aims to establish a prospective nationwide cohort of venous thromboembolism. The main questions it mains to answer are: Which patients with venous thromboembolism should accept long-term anticoagulation therapy? Mechanism and prognosis of venous thromboembolism. Participants will receive yearly follow-ups through telephone, hospitalization, or outpatient care.
