Filter by: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.
The purpose of this research is to learn more about how what the Apple watch measures, in terms of walking data, heart rate, breathing rate, and sleep habits, relates to how participants feel. During the course of the treatment, the symptoms participants experience change, and whether the Apple watch can detect these changes. Ultimately, this knowledge is being used to design proactive tools and signatures that can predict complications or symptom changes before they happen.
The aim of this study is to evaluate the feasibility of randomizing individuals to low molecular weight heparin (enoxaparin) or no treatment following cesarean delivery. The investigators hypothesize that among eligible individuals, at least 35% will enroll, undergo randomization, and complete the allocated treatment group.
The thromboembolic disease is a common complication of patients admitted to conventional hospitalization units. To prevent such complications, thromboprophylaxis is indicated in high-risk patients identified with validated risk-assessment models such as Padua score and IMPROVE-VTE score. However, the relation between thromboembolic disease and inpatients is yet to be demonstrated in new clinical settings such as at home hospitalization units. Moreover, patient immobilization is key in the pathogenesis of thromboembolic complications: therefore, it is crucial to collect raw data of patient mobility during admission. The goal of this observational study is to compare the thromboembolic risk of patients admitted with acute medical diseases to at home hospitalization units with conventional hospitalization units. The main questions it aims to answer are: - Is the estimated thromboembolic risk of patients admitted with acute medical diseases to at home hospitalization units similar to those admitted to conventional hospitalization units? - Are the risk-assessment models used to predict thromboembolic risk of patients admitted with acute medical diseases to conventional hospitalization units (Padua and IMPROVE-VTE score) valid in at home hospitalization patients? Participants admitted with acute medical diseases to either a conventional hospitalization unit or at home hospitalization units will be included in a prospective registry in order to investigate the 90 days incidence of thromboembolic disease. A cohort of such patients will be controlled with triaxial accelerometer in order to collect raw data regarding patient mobility during admission.
The goal of this clinical trial is to assess the effect of Balloon Pulmonary Angioplasty (BPA) on quality of life and exercise capacity in patients with chronic tromboembolic pulmonary disease (CTEPD) without pulmonary hypertension (PH). The main question[s] it aims to answer are: - What is the effect of BPA on quality of life, measured with the PEmb-QoL-questionnaire, in patients with CTEPD without PH? - What is the effect of is the effect of BPA on exercise capacity in patients with CTEPD without PH? This study is a randomised clinical trial with cross-over design. Participants will be randomised in an intervention and a control group. At baseline, questionnaires and exercise tests will be perfomed in all patients. The intervention group will first receive BPA-treatment. After 6 months, all patients will fill in the questionaires and undergo the exercise tests. At this point the control group will also receive BPA-treatment. After 12 months the study outcomes will be measured in all participants with the same questionnaires and exercise tests. The total follow-up is 24 months.
The goal of this clinical trial is to evaluate tailored duration of long-term anticoagulant treatment after a first venous thromboembolism based on individualized risk assessments of recurrent VTE and major bleeding risks. Participants will be asked to fill in a questionnaire and take a buccal swab, which are used for an individual estimation of the risks of recurrent VTE and bleeding. Based on these risks a treatment advise will be made, or randomised in a subgroup of patients.
