Active clinical trials for "Venous Thrombosis"

Deep venous thrombosis is the presence of blood clots, usually in the legs that lead to either local problems or breathing problems if the clot moves to the lungs. This study is designed to assess both clinical conditions as well as common genetic factors that lead to more risk of deep venous thrombosis. Clinical conditions of venous thrombosis include: stroke, malignancy, and situations such as surgery, pregnancy, trauma, or travel.

Venous thromboembolism (VTE) is a serious preventable complication of gynecological surgery. High incidence of silent VTE before surgery seems attributable to the high incidence of VTE after surgery in ovarian cancer .so the aim of work is to detect silent venous thrombosis in gynecological patients suffering from pelvic masses using different imaging modalities .

Prevention and Prophylaxis (Thromboprophylaxis - ACT) of Cancer Associated Thrombosis (CAT) in High Risk Oncology Patients: ACT4CAT.

The objective of the "anticoagchoice" study is to analyze the preferences of people suffering from phlebitis, in terms of anticoagulant, to improve adherence to these treatments, to adapt the medical prescriptions.

This is a prospective chart study that will aim to assess objective data on compliance levels to low molecular weight heparin (LMWH) injections among pregnant and postnatal women undergoing VTE thromboprophylaxis treatment at Cork University Maternity Hospital. This is a study that will help shine light on accurate data for compliance and possible factors affecting it, which will be useful for more individualised treatment plans for future patients. Patients at higher risk of Venous thromboembolism undergoing VTE thromboprophylaxis will be invited to participate in the study. Once the patient reads the information leaflet and signs consent, data will then be collected from the patients medical record. The patient will be given a smart sharps bin with an individual, unique product code. This device will be provided by HealthBeacon, a Dublin based start-up company. The device will be personalised with the treatment schedule pre-loaded onto it. When a used LMWH injection is disposed into the smart sharps bin, an infrared sensor is activated. The system captures an image of the injection in the chamber before moving it to the normal 'sharps' container of the bin for disposal. The captured image is time-stamped and sent to HealthBeacon's electronic database. HealthBeacon will only have the data pertaining to the disposal of injections for each sharps bin (i.e. the timing of the disposal of each used injection in each pre-coded bin). We are blinded to the compliance information and will only will receive the raw Data once treatment is completed. Data will be analysed to determine compliance of LMWH injections. This study will enable us to have a better insight on accurate compliance rates for LMWH injections in pregnant women at higher risk for venous thromboembolism (VTE). Understanding compliance with LMWH injections and the factors which can affect it, will hopefully guide future information and education that we offer to patients who are prescribed LMWH injections and help decrease maternal mortality rates in future.

This clinical trial is destinated to evaluate if the periodic screening for deep venous thrombosis by ultrasound of lower extremity in patients with intensive care unit (ICU) patients with COVID 19 impacts on mortality, ICU stay and total lenght of stay in the hospital, along with other outcomes.

Autoimmune diseases are diseases in which inappropriate immune responses that have the capability of harming host cells play an important role. Evidence suggests that the presence of certain autoimmune diseases such as rheumatoid arthritis or systematic lupus erythematosus increase the risk of cardiovascular disease (CVD). However, this evidence is inconsistent for autoimmune disorders and no systematic approach has been previously used to study the relationship between a range of common autoimmune disorders and specific forms of cardiovascular diseases such as myocardial infarction, intracerebral and subarachnoid haemorrhage, or venous thrombosis. The investigators will use linked electronic health records to investigate whether commonly diagnosed autoimmune disorders are associated with increased risk of CVD development and whether effects differ in men and women and change with age.

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.

Introduction: Venous thromboembolism (VTE), including both deep vein thrombosis and pulmonary embolism, is a frequent cause of morbidity and mortality. The population of critically ill patients is a heterogeneous group of patients with an overall high average risk of developing VTE. No prognostic model has been developed for estimation of this risk specifically in critically ill patients. The aim is to construct and validate a risk assessment model for predicting the risk of in-hospital VTE in critically ill patients. Methods: In the first phase of the study we will create a prognostic model based on a derivation cohort of critically ill patients who were acutely admitted to the intensive care unit. A point-based clinical prediction model will be created using backward stepwise regression analysis from a selection of predefined candidate predictors. Model performance, discrimination and calibration will be evaluated, and the model will be internally validated by bootstrapping. In the second phase of the study, external validation will be performed in an independent cohort, and additionally model performance will be compared with performance of existing VTE risk prediction models derived from, and applied to, general medical patients. Dissemination: This protocol will be published online. The results will be reported according to the Transparent Reporting of multivariate prediction models for Individual Prognosis Or Diagnosis (TRIPOD) statement, and submitted to a peer-reviewed journal for publication.

Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common post-operative complication. The necessity for anticoagulant therapy after orthopedic surgeries is widely understood, but treatment administration patterns in the prevention of venous thromboembolism (VTE) after orthopedic surgeries during the hospital stay have yet to be examined. The main objective of this study is to perform a comparative effectiveness review examining the benefits and harms associated with venous thromboembolism prophylaxis in patients undergoing orthopedic surgeries. It is around efficacy and safety evaluation of using anticoagulant for thromboprophylaxis in patients undergoing orthopedic surgeries taking into the account the reliable selection of patients most benefit. The aims of this study is to analyze patient records in teaching hospitals database of our country (including: Hanoi Medical University, Bach Mai Hospital, Cho Ray Hospital, Viet Duc University Hospital) and compare the outcomes and costs between different types of anticoagulant medications that were prescribed for the prevention of VTE following orthopedic surgeries. This analysis will assess and quantify the outcomes, resource utilization, and cost of care for patients receiving rivaroxaban or enoxaparin. The outcomes of interest include the occurence of DVT and PE, rates of major bleeds, medical resource utilization, and total costs (medical plus pharmacy).
