Filter by:The aim of the study isto evaluate the inter-observer reliability of the assessment of venous thromboembolic risk using the TRiP(cast) score in patients presenting with trauma to a lower limb requiring immobilisation, and of the clinicians' assessment using the physician's implicit probability (gestalt) compared with the use of the TRiP(cast) score.
The goal of this observational study is to analyse the association between anti-factor Xa activity (antiXa) and the occurence of venous thromboembolism (VTE; either deep vein thrombosis and/or pulmonary embolism) in critically ill patients who are admitted to an intensive care unit. The main questions it aims to answer are: - What is the association between antiXa and VTE? - What is the association between antiXa and symptomatic, respectively incidental, VTE? - How is pharmacological anticoagulation with enoxaparin related to measured antiXa? - What is the association between antiXa and bleeding complications. - What is the incidence of venous thromboembolism in patients treated at an intensive care unit? - How is the occurence of VTE related to patient-centred outcomes such as mortality, quality of life, length of stay and days outside of the intensive care unit/hospital.
The goal of this quasi-experimental study is to examine the effects of a venous thromboembolism prevention program, or "5E" program, on the rates of venous thromboembolism in patients with spinal cord disorders. The main questions it aims to answer are: - Will participants receiving the 5E program have lower rates of venous thromboembolism compared to those receiving the usual care? - Will participants receiving the 5E program have lower scores of venous thromboembolism signs and symptoms compared to those receiving the usual care? - Will the average thigh and calf circumferences of participants before and after receiving the 5E program be different? Participants in the intervention group will receive the 5E program, including - Education: health education regarding venous thromboembolism prevention - Elevation: leg elevation of 10-20 degrees - Exercise: ankle exercises - Enough fluid: adequate fluid uptake - Early application of intermittent pneumatic compression (IPC): IPC use within 48 hours after admission
This is an observational study in which only data will be collected from children with venous thromboembolism who are prescribed rivaroxaban or warfarin by their doctors. Venous thromboembolism (VTE) is a condition in which people have problems due to the formation of blood clots in their veins. The study drug rivaroxaban is an approved treatment for VTE in children and adults in Japan. It is a blood thinner that prevents the blood from clotting by blocking a protein responsible for blood clotting. Warfarin is another blood thinner that is available for VTE. In this study warfarin is the reference drug. A previous study was carried out to learn about how well rivaroxaban works and how safe it is in children with VTE. However, to better understand the safety of this drug in children, more knowledge is needed about the use of rivaroxaban in the real world. The main purpose of this study is to learn more about the occurrence of major bleeding in children taking rivaroxaban. Major bleeding can be bleeding within the skull, bleeding inside the eye, bleeding from an organ in the digestive system, or bleeding which requires being given blood from a donor. In addition, this study will help learn more about the following in children with VTE: - The occurrence of major bleeding during treatment with rivaroxaban and during treatment with warfarin - The occurrence of bleeding of importance in children being treated with rivaroxaban and in children being treated with warfarin. Bleeding of importance in children can be: bleeding from the lung, blood in the kidney, heavy menstrual bleeding - The occurrence of major bleeding and bleeding of importance in children who are taking drugs called anti platelet agents and NSAIDs to prevent blood clots at the same time as rivaroxaban, who are taking a drug that blocks the action of a protein called 'CYP3A4' at the same time as rivaroxaban, who have reduced kidney function, who have taken rivaroxaban for a long time, or who have taken other drugs by mouth to prevent blood clots before starting rivaroxaban - The occurrence of repeated VTE on treatment with rivaroxaban and on treatment with warfarin The children with VTE in this study are already receiving rivaroxaban or warfarin treatment as part of their regular care from their doctors. The data will come from an electronic health records database created by a company called Medical Data Vision. The data will be collected between January 2021 and June 2024. Researchers will look at the health information from children less than 18 years of age with VTE in Japan who are prescribed treatment with rivaroxaban or warfarin during the study period. In this study, only available data from routine care are collected. No visits or tests are required as part of this study
Venous thromboembolic disease (VTE) is a frequent and potentially serious pathology. Therapeutic management has improved considerably over the last few decades, enabling the application of codified management in line with the recently updated French management recommendations. One of the main remaining difficulties concerns VTE sequelae, mainly post-thrombotic syndrome after deep vein thrombosis, and post-pulmonary embolism syndrome after pulmonary embolism. The mechanisms leading to the absence of complete repermeabilization of vessels affected by Venous thromboembolic disease (VTE) are still poorly understood. The concept of immunothrombosis, closely associating immunity, inflammation and thrombosis, could (in part) explain the appearance of these sequelae. Platelets appear to play a key role in the onset of sequelae: Platelets are known to be involved both in the onset of a VTE episode and in the inflammatory response. This involvement is illustrated by the expression of inflammatory receptors such as TLR (toll-like receptor) 2 and TLR4. Th aim to investigate the role of platelets in the occurrence of sequelae, mainly via their role in the inflammatory response, in Venous thromboembolic disease (VTE) patients.
Glioma is a common brain tumor with a high risk of venous thromboembolism during treatment, especially in the months after surgery. Postoperative lower extremity dyskinesia in patients with gliomas is considered as a high-risk factor for venous thromboembolism. Rivaroxaban, as an oral anticoagulants, has similar effect in the prevention and treatment of tumor-related venous thromboembolism compared to low molecular weight heparin. Given the lack of prospective supporting data, the efficacy and safety of rivaroxaban in the prevention of postoperative venous thromboembolism in glioma patients with postoperative lower extremity dyskinesia need to be established.
There's no unified recommendation in clinical practice regarding adjusting dosages for different patient types, especially when adverse events occur. While rivaroxaban typically doesn't require coagulation monitoring, in elderly patients, particularly those with multiple medications, finding appropriate lab indicators becomes crucial to gauge its anticoagulant effect. This aids in evaluating precise rivaroxaban dosing for the elderly, balancing bleeding risks and recurrence. Clinical pharmacological studies suggest that drug pharmacokinetics and pharmacodynamics in different populations can guide dosage optimization. Hence, this study aims to provide a basis for optimizing dosing regimens in high-risk elderly patients in China by exploring pharmacokinetic and pharmacodynamic indicators in clinical practice.
This study was to compare the study drug KN060 to enoxaparin, for the prevention of blood clotting and safety in patients undergoing total knee arthroplasty (TKA).
This study is a multicenter cross-sectional study conducted at 20 centers. Data of existing inpatients in 20 community hospitals were collected. Information collected included demographic, co-morbidities, co-medication, laboratory tests, imaging tests, and anticoagulant use. Based on Caprini, Padua, Khorana and PAPT rating tables, VTE risk assessment was carried out for inpatients from 20 community hospitals, and VTE risk stratification of patients and prevention of high-risk VTE patients were analyzed. Blood samples of inpatients were collected to determine coagulation function indicators. VTE screening was performed on hospitalized patients using color Doppler ultrasound to determine the incidence of VTE in community hospitalized patients. On this basis, the predictive efficacy of different VTE risk scores on community hospitalized patients was compared, and a new VTE risk score conforming to community hospitalized patients was constructed.
Individuals attending the hospital to undergo operations are at risk of developing blood clots in the legs, known as deep vein thrombosis (DVT). 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 lungs' ability to move oxygen from the air into the blood and may be life-threatening. This is known as pulmonary embolism (PE). DVT and PE are known collectively as venous thromboembolism or VTE. The importance of preventing VTE in surgical patients is widely recognised, with two main strategies used: thinning the blood with regular injections and/or tablets and wearing elastic stockings to help stop blood from sitting in the leg veins where it can clot. Evidence for using elastic stockings to prevent VTE has recently been challenged. Additionally, there is a lack of evidence for the additional benefit of stockings over and above that of blood thinning medications. If stockings were to reduce VTE over and above blood thinning medication, these benefits need to be weighed against the risks and disadvantages of stockings, including discomfort, restricting blood flow to the leg causing blisters and wounds in addition to the cost. If stockings were found not to reduce the risk of clots, they would no longer need to be used in these patients, thus reducing the disadvantages of stockings, and saving the NHS millions of pounds per year. Certain types of operations (300,000 per year in the UK) are linked with a particularly high risk of VTE, including cancer surgery, surgery in the abdomen and pelvis, and bone (orthopaedic) surgery. In these cases, patients are offered blood thinning medications both during their hospital stay and for a period after they have left the hospital. Furthermore, these patients are offered stockings to wear while in the hospital. It is not known if, in patients who receive blood thinning medications both in hospital and after discharge, the addition of wearing stockings whilst in hospital reduces their risk of VTE any further. The purpose of this study is to investigate if it is worthwhile using stockings, in addition to blood thinning medication, to reduce blood clots after surgery. People enrolled in the study will be those at the highest risk of VTE and require an extended period of medication to reduce the risk of a blood clot. A computer will randomly choose one of the below treatments by chance to make the trial fair: A) Extended duration clot-reducing medicine in addition to stockings B) Extended duration clot-reducing medicine alone The surgery and all the other medical care will continue as normal. Everyone in the study will get an ultrasound scan at 21 - 35 days after their operation to check if they have developed a blood clot. This is an additional scan, not routinely performed in the NHS, to make sure that all blood clots are detected at an early stage. Participants will receive a phone call at 7, 21-35 and 90 days after their treatment to see if they have developed a blood clot or had any problems with the treatment.
