Filter by:Background: venous thromboembolism (VTE) is a common complication in critically ill patients, admitted to the Intensive Care Units (ICUs). At the present time, there is no validated score to estimate risks and benefits of antithrombotic pharmacological prophylaxis in this subset of patients. Aim of the study: investigating potential harms and benefits of a protocol for systematic screening of DVT in critically ill patients, admitted to an ICU. Expected relevance: systematic screening for deep vein thrombosis (DVT) through ultrasound (US) lower limb veins examination could help defining the indication to antithrombotic pharmacological treatment, but no protocol of systematic screening has been validated so far. Furthermore, the screening could be associated with over-diagnosis and consequent over-treatment, as well as increased management burden for the caregivers and higher healthcare costs.
This retrospective cohort study aims to characterise outcomes for patients treated on an intensive care unit (ICU) with COVID-19 in England and Wales, one year after discharge from hospital. Outcomes will be compared with patients admitted as an emergency to an ICU for other conditions. The study will use existing national audit data linked to routine healthcare datasets.
In patients with symptoms of Venous Thromboembolism (VTE) (mainly deep vein thrombosis (DVT) or pulmonary embolism (PE)), the study will evaluate the agreement between the D-Dimer measurements from the LumiraDx POC D-Dimer assay and a reference method, as an aid in diagnosis, assessment and exclusion of DVT and PE.
This is a prospective, multi-center, single-arm, non-blinded clinical trial designed to investigate the safety and efficacy of the Vesper DUO Venous Stent System as compared to a pre-defined performance goal (PG) established from published, peer reviewed scientific literature related to stenting of iliofemoral venous outflow obstructions.
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).
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.
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.
P5.fi study - P4 together with a fifth 'P' and '.fi' for population health Finally Implemented in Finland - studies the value of returning genetic and metabolomic risk information in two diseases (coronary heart disease and type 2 diabetes) and one feature (venous thromboembolism). The hypothesis of the study is that 1) combining genetic and metabolic risk with traditional risk factors adds value to the personal risk assessment of these diseases, 2) such risk information can be provided to individuals using a web based user portal in an easily understandable and useful format, and 3) receiving genetic and metabolomic risk information has an effect on the health of the study participants. The study is a continuation of FinHealth 2017 -study, which involved more than 7,000 Finns from around the country. The participants of FinHealth were invited to participate in P5.fi -study. The new research utilises information, samples, and measurements obtained in the FinHealth Study. Prospective clinical significance of selected genetic and metabolomic risk scores will be studied in 30.000 Finnish individuals. The study will analyze the genetic and metabolomic profile of the P5.fi participants and develop and test a protocol for returning them health related risk information. The impact of the intervention will by followed up by questionnaires and national health registers for five years.
FEVRIER study is an observatory of hospitalizations in cardiology units in sub-Saharan Africa.
The ASPIREX®S Endovascular System is a rotating and aspirating catheter system. It is intended to be used for the percutaneous transluminal removal of fresh thrombotic or thromboembolic material from native blood vessels (or vessels fitted with stents, stent grafts or native or artificial bypasses) outside the cardiopulmonary, coronary and cerebral circulations. CAPTUREX® , a catheter with a filter basket, is intended to be used for the filtering of emboli from blood vessels during potentially embolizing procedures on the patient. ASPIREX®S and CAPTUREX® are CE-marked (Class III) medical devices. In this study the effectiveness and safety in the removal of thrombi in veins is assessed under real life setting.
