Filter by:Direct Oral Anticoagulants INTRODUCTION: DOAC's looks like an attractive alternative to VKA because they offer important advantages beyond their easiness of administration, like less interactions and no need of laboratory monitoring. 1 All oral anticoagulant regimens but not aspirin were associated with a lower risk of recurrent VTE, while only VKAs were associated with a higher risk of major bleeding. 2 There have been significant differences between VKAs and DOACs in the risk of major bleeding by the current study size. Even though the risk of major bleeding with VKAs may be lower in patients already challenged to anticoagulation treatment. 3 Furthermore, when deciding on longer term secondary prevention of VTE, DOACs appeared safer than standard-intensity VKAs, taking clinically relevant bleeding or any bleeding into consideration.4-5 Until now there is no randomized controlled trial assessing the role of oral direct anticoagulant as a prophylaxis for catheter associated venous thromboembolism. Aim of the work: To evaluate the efficacy of direct oral anticoagulants as a prophylactic anticoagulation in thromboprophylaxis of catheter induced thrombosis.

To compare the in hospital clinical outcomes in terms of efficacy and safety of deferred stenting versus non-deferred stenting in STEMI patients with high thrombus burden undergoing primary percutaneous intervention.
Point-of-care ultrasound (PoCUS) is a rapidly evolving method of clinical assessment within the intensive care unit (ICU) with training predominantly aimed at physicians. Routine whole-body PoCUS (lungs, heart, abdomen and blood vessels) when conducted by physicians benefits patient care and outcomes including reducing the risk of prolonged ICU stay (>7 days) and mechanical ventilation as well as reducing utilisation of other diagnostic tests. However, physician-only use of PoCUS does not allow for use as a routine assessment method in the ICU due to the low physician to patient ratio and poor ultrasound accreditation rate. Providing other healthcare professionals such as Advanced Critical Care Practitioners (ACCPs), ICU nurses and physiotherapists with PoCUS skills increases the proportion of trained staff to perform routine PoCUS in the ICU. This could aid earlier identification of abnormal pathology, earlier treatment, and prevent patient deterioration. The advancement of handheld PoCUS technology is making ultrasound more portable, cheaper and easier to use. The increased accessibility of PoCUS combined with growing evidence of its diagnostic accuracy compared to other modes of imaging means PoCUS use is gaining traction globally. However, little to no research exists investigating the feasibility of implementing scheduled interprofessional PoCUS in the ICU and its impact on patient outcomes. This study aims to evaluate the acceptability and feasibility of a quick and simple whole body ultrasound scan performed by trained ACCPs, ICU nurses, physiotherapists, and doctors at set time points throughout the patients ICU stay. The investigators want to find out the most common barriers and facilitators to intervention implementation and to explore the key clinical outcomes for use in a future definitive RCT.
Activated clotting time (ACT) is currently recommended to monitor high concentrations heparin anticoagulation. ACT-LR was specifically designed to measure the activity of low dose of heparin used during endovascular surgery. The correlation between ACT-LR and Anti Xa activity which is considered as the gold standard seems to be debated. Few studies in literature had shown controversial results. These studies were conducted in patients who underwent open as endovascular surgery. However, the ACT monitoring is not recommended in open surgery. In addition, heparin administration protocols are not described and specific to each centre. In this study investigators want to study the correlation between LR-ACT and anti Xa after introducing a heparin protocol during complex endovascular procedures.
The occurrence of VTE in hospital is an important cause of unexpected death of inpatients, and has become a serious problem faced by hospital managers and clinical medical staff.Under the target of "Improving the Standard Prevention Rate of Venous Thromboembolism" proposed in the "National Medical Quality and Safety Improvement Goal in 2022", it is urgent to establish a highly sensitive VTE risk assessment and monitoring system.At present, VTE risk assessment scale is used for risk screening and monitoring in combination with D-dimer in clinical practice, but D-dimer has low specificity and poor sensitivity, which makes it impossible to accurately assess the risk of venous thrombosis.Therefore, it is very important to explore highly specific molecular markers of thrombosis for VTE risk assessment.This project will analyze the value of single or combined detection of different thrombus molecular markers in VTE risk assessment, establish the best VTE risk assessment scheme, improve the standardized prevention of VTE, realize the early intervention of VTE, truly achieve early detection, early prevention and early treatment, and effectively reduce the occurrence of VTE.
Hepatocellular carcinoma (HCC) is the fifth most common neoplasm worldwide and the third most frequent cause of death from cancer in the world. Hepatocellular carcinoma is responsible for significant morbidity and mortality in cirrhosis. Most cases of HCC occur in the setting of cirrhosis and, therefore, prognosis is determined not only by factors related to the tumor but also by factors related to cirrhosis (1). According to previous reports, the incidence of HCC with partial portal vein thrombosis (PVTT) ranges between 44% and 62.2%. HCC associated with PVTT has a poor prognosis. It may lead to intrahepatic metastasis, liver dysfunction, and portal hypertension. The median overall survival for HCC patients with untreated PVTT is only 2.7 months (2). It was suggested that HCC with PVTT should be classified as stage C based on Barcelona Clinic Liver Cancer; it is no longer surgically treatable. Compared with conservative treatment, TACE is a safe and effective therapy for such cases. However, this modality for treatment might be associated with mortality (3). As far as we know, there is no studies of short-term survival in patients with HCC and PVT after TACE in our locality. Our study aims to determine frequency of short-term mortality (< 3month) among HCC patients with PPVT after TACE, and to explore its predictors.
Oncology and hemotology patients under anticancer treatments are exposed to increased risks of central venous catheter-related complications due to the underlying cancer and its treament. This prospective observational monocentric french study aims at describing the incidence of such complications, their morbimortality, and analyzing some risk factors in order to contribute to propose some strategies to reduce these complications' rate and consequences
Varicose veins of lower extremities are the most common disease in vascular surgery, and daytime surgery has gradually become the mainstream of varicose veins of lower extremities. Superficial venous thrombosis is one of the common complications of varicose veins of lower limbs. Current consensus is that patients with superficial venous thrombosis should be treated with standardized anticoagulant therapy to prevent their progression to venous thrombotic disease.SVT patients need standardized anticoagulant therapy for a period of time, while DS is current mainstream treatment of VV. Will the existence of SVT affect the safety and efficacy of DS of VV, leading a need of changing the treatment strategy and carrying out anticoagulant treatment for SVT before DS on VV patients? To date, there is no research on this issue. Therefore, we conducted this study to comprehensively evaluate the safety, feasibility, perioperative and long-term efficacy of DS in VV patients complicated with SVT, and systematically compared patients who had VV only.
This is a parallel assigned, open-label, perspective trial studying the safety and efficacy of intensity-modulated radiotherapy (IMRT) combined with PD-1 Blockade and Lenvatinib for Hepatocellular Carcinoma (HCC) with Vp3 Portal Vein Tumor Thrombus (PVTT, Japanese Liver Cancer Study Group classification) before liver transplantation.
The chemoprophylaxis of deep vein thrombosis (DVT) with subcutaneous low-molecular-weight heparin (enoxaparin) in the postoperative period of elective surgeries is already well established in the literature and in clinical practice. However, the use of this medication can have a financial impact on the patient and the parenteral presentation itself is associated with pain at the application site, which can make it difficult for patients to adhere.
