Filter by:The main objective of the study is to determine the incidence of deep vein thromboses at Doppler echo in patients with SARS-Cov-2 pneumopathy upon their entry into ICU and after 7 days of hospitalization in ICU. This is a monocentric interventional study (RIPH 2).
Patients with COVID-19 in the Intensive Care Unit (ICU) or hospitalized with severe form have a poor prognosis (almost 30% rate of death). They present often a high cardiovascular risk profile (almost 30% of hypertension and 19% of diabetes). Troponin has been described to be elevated in a high proportion of patients (one fifth of all patients and 50% of non-survivors) suggesting the possibility of cardiomyopathies. High levels of DDimers (81% of non survivors) and fibrin degradation products are also associated with increased risk of mortality suggesting also the possibility of venous thromboembolism. Therefore, screening for cardiomyopathies and venous thromboembolism could represent an important challenge for patients with COVID-19 management.
This is a prospective cohort study of 30 patients who are 8-21 years of age with venous thromboembolism (VTE)- either lower extremity deep venous thrombosis (DVT) or pulmonary embolism (PE).
In France, venous thromboembolic (VTE) disease is usually managed by vascular medicine physicians (VMP). The national OPTIMEV study, conducted more than 12 years ago among VMP practicing in hospital and in the community described the management of VTE in routine clinical practice. Since then a large number of practice changing studies have been published. This includes trials that have validated the use of direct oral anticoagulants (DOAC), the new standard of care of VTE, as per new national and international guidelines. Management of VTE in 2019 appears to be significantly different from the one that prevailed more than 10 years ago when the last national survey was conducted. It is therefore important to have an update on the routine clinical practice management of VTE by VMP. In this perspective the investigators aim to conduct a national survey among VMP practicing in France
This study will involve blood draws to test for specific cytokines. The study goal is to gain a better understanding of the role of inflammatory response in the development of specific complications in burn and TENS patients.
The objective of this study is to compare oral rivaroxaban with injectable enoxaparin in orthopaedic trauma patients to determine if orally administered rivaroxaban once daily carries greater compliance and overall satisfaction than enoxaparin self-administered by subcutaneous injection once daily.
Design: U.S.-based, single-center, randomized placebo-controlled trial. Brief Treatment Description: Low-intensity apixaban (2.5mg twice daily) for extended-duration secondary prevention of VTE after initial treatment for provoked VTE. Purpose: To establish the safety and efficacy of low-intensity apixaban versus placebo for extended prevention of recurrence after provoked VTE in patients with at least one persistent provoking factor. Population: Outpatients with provoked VTE with at least one persistent provoking factor. Enrollment: 600 subjects Randomization: 1:1 Clinical Site Locations: 1 center (Brigham and Women's Hospital) Study Duration: 36 months; enrollment period of up to 20 months with 12-month follow-up. Primary Safety and Efficacy Outcomes: Primary Safety Outcome: International Society on Thrombosis and Haemostasis (ISTH) major bleeding at 12 months. Primary Efficacy Outcome: Symptomatic, recurrent VTE, defined as the composite of deep vein thrombosis and/or pulmonary embolism at 12 months. Secondary Efficacy Outcome: The composite of death due to cardiovascular cause, nonfatal myocardial infarction, stroke or systemic embolism, critical limb ischemia, or coronary or peripheral ischemia requiring revascularization (major adverse cardiovascular events, including major adverse limb events) at 12 months. Follow-Up: Follow-up will consist of Electronic Health Record (EHR) review at 12-months from study enrollment. Interim Analysis: An interim analysis for the primary safety and efficacy outcomes will be performed when 300 subjects have completed 12-month follow-up.
The goal of this study is to determine if early placement of a midline catheter in patients with a central venous catheter (CVC) will decrease the number of days the CVC is in place. Patients who are in the medical intensive care unit (MICU) and have a CVC may be approached to join the study. Those who meet study eligibility and provide written consent will be enrolled. The longer the CVC remains in place,the greater the chance of developing an infection or blood clot. Any IV line that is placed (CVC, midline, peripheral line) comes with the risk of infection or blood clots, although that risk is generally less with the midline and peripheral IV lines than a CVC. The treating team will make the decision when to remove the CVC. The timeline of removal will be compared to previous data collected on patients similar to the ones in this study. During their hospital stay, study patients will be monitored for how well the midline catheter is functioning as well as if they develop a catheter related blood clot or infection.
Patients with a deep vein thrombosis (DVT) may develop long-term symptoms, e.g. lifelong leg pain, skin changes and occasionally ulceration, known as post-thrombotic syndrome (PTS). This affects about half of people with a history of DVT. This randomised study aims to show whether the regular use of a compression stocking after DVT in the leg, prevents long-term pain, swelling and ulceration. Currently small trials show varied results and a large trial is required to answer the question.
Deep venous thrombosis(DVT) is a blood clot, usually affecting the legs, causing pain, swelling, and redness. The clot damages the veins, which can result in chronic pain, swelling and ulceration. This is called the post-thrombotic syndrome, which impacts heavily on patients' life and work. If the clot dislodges and travels to the lungs, it becomes a pulmonary embolus (PE), which can be life threatening. Together, DVT and PE affect 500,000 people in Europe every year, representing the most common cause of hospital acquired death. They are expensive diseases due to the cost of treatment and the days lost from people being unable to work. DVT is diagnosed by clinical examination, risk scoring and a blood test called D dimer, a product of the clot. If negative, it is unlikely that DVT is present. However, many conditions can raise D-dimer levels, making it less useful when positive. Ultrasound can confirm the presence of clot but often this is not seen. The clot can take time to form and patients may not experience symptoms immediately. This is a problem for treatment, as new, clot-busting medication works best in the first 2 weeks after a DVT and it is difficult to tell when the clot formed. Metabonomics is highly sensitive technology that detects very small chemicals; it is being used successfully in cancer and is a tool that can help better understand DVT and generate new tests to help patients. Previous departmental work has shown that a chemical difference exists in patients with DVT. The aim of this study is to not only confirm the presence of these chemicals in a different group of DVT patients, but also to calculate chemical concentrations. This will improve the investigator's understanding of how DVT develops and provide a way to develop a test that is better than D-dimer.
