Filter by:Introduction: Venous thromboembolism (VTE) in the intensive care unit (ICU) is associated with significant morbidity and mortality therefore prevention is imperative to reduce its burden. VTE prophylaxis in ICU patients is primarily pharmacological using low molecular weight heparin. This study aims to determine the proportion of ICU patients receiving VTE prophylaxis that achieves appropriate anti-factor Xa activity (aFXa) prophylactic levels and to characterize this patient population Methods: Seventy-five patients admitted to the General ICU were included. Peak and trough aFXa levels were measured at 4 and 23 hours respectively after receiving the second consecutive daily enoxaparin 40 mg sc injection. Patients in whom peak aFXa levels were found to be sub-prophylactic, peak and trough levels were repeated as above
Liver transplantation is currently an effective treatment for end-stage liver disease. The high incidence of thrombotic related complications in the early postoperative period after orthotopic liver transplantation(OLT) has been attributed to many factors, such as the long operation time, the high trauma, the need for prolonged bed rest after operation, and the instability of coagulation status in the early postoperative period. Among them, venous thromboembolism (VTE) is one of the most common complications after liver transplantation, including deep vein thrombosis (DVT) and pulmonary embolism (PE), which seriously affect the survival of patients after transplantation. Although the Caprini score is currently recognized as a more mature thrombotic risk assessment tool in patients undergoing abdominal surgery. However, because of the long operation time of liver transplantation and central venous catheterization and other factors, the majority of surgical patients score ≥ 5 points, which are all very high-risk grades. It loses the power of this model for risk stratification and targeted prevention. How to correctly identify people at high risk of VTE after OLT, early diagnosis of VTE and aggressive implementation of correct preventive measures appear essential. Therefore, this study was designed as a single center case-control study to review and analyze the incidence, clinical characteristics, and associated risk factors of VTE after OLT, and to establish a nomogram risk assessment model and validate its predictive efficacy.
Retrospective monocentric registry to evaluate the efficacy and safety of different anticoagulants in patients with thromboembolic antiphospholipid syndrome
Thromboembolisms (TEs) in patients with critical COVID-19 has been reported to be three times higher than for other critically ill patients. Immunothrombosis has been proposed as a plausible mechanism for COVID-19 coagulopathy. Corticosteroids improve survival in patients with critical COVID-19, and likely even more so with a higher dose. However, the evidence regarding the impact on the incidence of thromboembolic and bleeding events are currently uncharted. The aim of this study is to investigate if there is a difference in the incidence of thromboembolic events during ICU stay in patients with critical COVID-19 when treated with 12 mg dexamethasone compared to 6 mg dexamethasone.
Study purpose was to study the safety and efficacy of Dimolegin - DD217 as a drug for prevention of thrombotic complications compared to Clexane (enoxaparin sodium) - the standard therapy currently prescribed to patients hospitalized with COVID-19. Patients who met all inclusion criteria and no exclusion criteria were randomized into two therapy groups: - Group 1 - test drug Dimolegin - DD217 (60 mg orally, 1 time per day); - Group 2 - reference drug Clexane (40 mg subcutaneously, 1 time per day). The study drugs were taken once a day until: - the discharge from the hospital due to recovery or positive dynamics; - or up to 30 days of the patient's stay in the hospital; - or until the Investigator decides to discontinue the therapy for other reasons. Planned: screening of up to 450 patients, randomization: 430 (215 per group). The required number of patients is 200 per group as a result of the entire study.
The main objective was to demonstrate the existence and importance of hypercoagulability in patients with IBD, by determining the prevalence of changes in coagulation parameters and evaluating the impact of these changes on the occurrence of thromboembolic events.
This is an observational study in which patient data from the past on venous thromboembolism (VTE) in patients with cancer is studied. VTE is a condition in which a patient has problems due to the formation of blood clots in the veins. Blood clots can reduce the flow of blood to vital organs such as the heart and lungs, which can lead to them becoming damaged. VTE can also be "recurrent". This means that the blood clots have returned after treatment. People who have cancer have an increased risk of developing VTE. Three main types of anticoagulation treatments ("blood thinners") have been available for patients with cancer who also have VTE - Low molecular weight heparins (LMWHs) - Vitamin K antagonists (VKAs) - Non-vitamin K antagonist oral anticoagulants (NOACs) The treatment rivaroxaban belongs to the NOACs. Compared to other treatments available to patients who have cancer and VTE, NOACs may cause fewer medical problems and can be easier for patients to take correctly. In this study, the researchers will collect data about: - the type of VTE treatments given and for how long the treatments are taken - the risk of blood clots returning in the veins after treatment, any events of major bleeding, and the number of deaths in patients with cancer who do not have a high risk of bleeding The researchers will compare this information in the patients - who received rivaroxaban to the patients who received LMWHs - who received NOACs to the patients who received LMWHs. There will be no required visits with a study doctor or required tests in this study. The researchers will look at the health information from adult patients in Sweden who were diagnosed with cancer between 2013 and 2019 and also have VTE. The researchers will collect this information from Swedish health registers including the Cancer Registry, National Patient Registry, Prescribed Drug Registry, and Cause of Death Registry.
The study is aimed at assessing the role of the activity of high-risk markers of thrombotic events (MCP-1, MIP1α, IP-10, phosphatedylserine, calreticulin) on the development of thrombotic complications in patients with COVID -19.
Patients with cancer are more likely than those without cancer to develop blood clots (deep vein thrombosis and pulmonary embolism), which are treated using blood thinners (anticoagulants). When clots occur, cancer patients carry a higher risk of recurring clots and more likely to bleed on blood thinning treatments. Therefore, it is critical to use blood thinners that optimize the safety and benefits. There are two main types of blood thinners that are recommended. The tablets which are direct-acting oral anticoagulants and the injections (low molecular-weight heparin). Clinical trials show the tablets may reduce clot risk but may potentially lead to more frequent bleeding, particularly in those with certain risk factors such as stomach ulcers, previous bleeding problems, certain cancer type. We aim to examine the effectiveness and safety of the tablets versus the injections for treatment of clots in cancer patients, to better understand these treatments' benefits and risks.
A prospective, multicenter, randomized controlled trial of the FlowTriever System compared to Catheter-Directed Thrombolysis (CDT) for use in the treatment of acute pulmonary embolism. The trial includes a non-randomized cohort of subjects with an absolute contraindication to thrombolysis.
