Filter by:Main research question: What is the present venous thrombosis incidence and what are the current practices of prescribing thromboprophylaxis in patients with multiple myeloma (MM)? Design: The present study is a retrospective cohort study. The patients will be selected from the electronic patient dossier (EPD) of the University Medical Center Groningen (UMCG). The present study will include newly diagnosed adult patients with a first MM at the UMCG between 1st of January 2014 and 1st of September 2021. The primary outcome of the study is the incidence of venous thromboembolism (VTE) with one year of diagnosis of MM. The investigators will also describe the various thromboprophylaxis regimens used and their corresponding VTE incidence. The secondary outcome will be the incidence of arterial thrombosis (AT) within the same period of time. Possible confounders are the therapy administered for MM, thromboprophylaxis type, age and patient comorbidities. Lastly, the third outcome will be a description of current thromboprophylaxis practices in the UMCG. Each outcome will be described separately. Expected results: Based on the study by de Waal et al in which they included 474 MM patients treated at the UMCG and at 4 hospitals in the province Friesland, the investigators expect to record a VTE incidence of approximately 15%.
Venous thromboembolism affects around 10 million people per year worldwide, however, despite its high incidence, there is no systematic review or randomized trial focused on the treatment of patients with recurrent deep vein thrombosis (DVT) and/or or pulmonary embolism (PE) during anticoagulant treatment. The objective was to compare the use of Rivaroxaban plus Aspirin versus Acenocoumarol in patients with recurrent venous thromboembolism treated with rivaroxaban.
Venous thromboembolism (VTE) is a common cause of morbidity and mortality among critically ill patients. No uniform standard model of VTE risk for critically ill patients was formatted by now. In 2020, Viarasilpa et al. developed the ICU⁃VTE rating table, mainly for ICU patients. However, it lacks validation. We examined and compared how well the ICU-VTE score predict and stratify VTE risk in comprehensive ICU patients.
Little is known about the current management status of venous thromboembolism (VTE) in Southwestern China. We aimed to investigate the status of anticoagulant administration in VTE in Southwestern China and assess the potential predictors of deep vein thrombosis (DVT) complicated pulmonary embolism (PE). We extracted data from YiduCloud database from December 2006 to November 2018 and performed a cross-sectional survey of VTE. The demographics, laboratory tests, and anticoagulants were collected and analyzed in the logistic regression model, classification tree and Random Forest model.
This is an observational study in which patient data from the past on venous thromboembolism (VTE) in people with cancer is studied. In observational studies, only observations are made without specified advice or interventions. People with VTE have 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 lungs, which can lead to their damage. VTE can also be "recurrent". This means that the blood clots have returned after treatment. People who have cancer are more likely to develop VTE, recurrent clots, and bleeding on blood thinning treatments. To prevent the formation of new or recurrent clots in people with cancer, a newer type of blood thinner is available, called direct-acting oral anticoagulant (DOAC). Rivaroxaban and apixaban are the most used DOACs in the US. They work by blocking a certain step in the blood clotting process, the activation of a protein called Factor X. Previous studies show that DOACs may reduce clot risk compared to other available treatments but may potentially lead to more frequent bleeding. Studies looking at these points in direct comparison of rivaroxaban and apixaban a currently missing. Therefore, this study will collect real-world data from the US to learn how well rivaroxaban works and how safe it is compared to apixaban in people with cancer and VTE who are at low risk for bleeding. To do this, researchers will look at the proportion of patients that will develop: - recurrent blood clots in the veins after treatment - bleeding in a critical organ - bleeding that requires a hospital stay within 3 and 6 months after participants had a VTE that was treated with rivaroxaban or apixaban. De-identified data collected will cover 12 months before and at maximum 6 months after this VTE. They will come from US electronic health records and will cover the years 2012 to 2020. No visits or tests are required as part of this study.
Aim of our study is to find frequency and risk factors for venous thromboembolism development in patients who underwent surgery for incisional ventral hernia. There were 240 patients enrolled in our retrospective observational cohort study. Included patients were operated for incisional hernia in Saveljev University Surgery Clinic from January 2018 to December 2019. Compression duplex ultrasound of lower legs veins was performed in 2-4 days after surgery for all participants. The primary endpoint was the occurrence of the venous thromboembolism event, including pulmonary embolism.
Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
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.
