Active clinical trials for "Thrombosis"

To improve the safety of diagnosis and therapy for a set of conditions and undifferentiated symptoms for hospitalized patients, the investigators will employ a set of methods and tools from the disciplines of systems engineering, human factors, quality improvement,and data analytics to thoroughly analyze the problem, design and develop potential solutions that leverage existing current technological infrastructure, and implement and evaluate the final interventions. The investigators will engage the interdisciplinary care team and patient (or their caregivers) to ensure treatment trajectories match the anticipated course for working diagnoses (or symptoms), and whether they are in line with patient and clinician expectations. The investigators will use an Interrupted time series (ITS) design to assess impact on diagnostic errors that lead to patient harm. The investigators will perform quantitative and qualitative evaluations using implementation science principles to understand if the interventions worked, and why or why not.

The purpose of this pilot study is to test feasibility of concept, consent and enrollment rates, and mechanics of study designed to assess if intra-catheter dwells of tissue plasminogen activator (t-PA) is effective in decreasing the rate of clinically diagnosed central line associated blood stream infection (CLABSI) or venous thromboembolism (VTE) in central venous catheters (CVC) compared to standard of care heparin dwell.

Asian populations have a lower rate of high-risk gene mutations of venous thrombosis, which means a reasonable perioperative anticoagulant management after hip or knee arthroplasty for Caucasian populations may be too excessive for Asians. So, individual patient risk assessment, rather than a "blanket policy", is considered the best thromboembolism prophylaxis for Asians.The purpose of this study was to evaluate the effectiveness and safety of selective thromboembolism prophylaxis compared with conventional thromboembolism prophylaxis by risk stratification with thromboelastography (TEG) after joint arthroplasty for Asian populations.

This study evaluates the safety and efficacy of AB023 (xisomab 3G3) in patients with end stage renal disease on chronic hemodialysis. Two dose levels will be evaluated in two cohorts. Within each cohort the patients will be randomized to receive either AB023 (xisomab 3G3) or placebo (at a ratio of 2:1 active: placebo).

In our study, investigators will investigate the effectiveness and complications of two catheter lock solutions one of which is the standard heparin routinely used in comparison to Sodium bicarbonate. Both solutions were used but not compared head to head. Investigators aim to compare both solutions in terms of catheter lumen patency and their effect on catheter-related infections.

The Michelle trial is expected to provide high-quality evidence around the role of extended thromboprophylaxis in COVID-19 and will help guide medical decisions in clinical practice.

The purpose of this study is to determine whether Apixaban, Warfarin and Aspirin Anticoagulation are effective and safe in Prevention of Portal Vein Thrombosis in Liver Cirrhotic Patients after Laparoscopic Splenectomy

The aim of the study is to evaluate efficacy and safety of venous thromboembolism prophylaxis by the combination of graduated compression stockings (GCS), standard doses of low-molecular-weight heparins (LMWH) and sequential compression device (SCD) in the mixed group of surgical patients at high and extremely high risk for venous thromboembolism.

Venous thromboembolism (VTE) encompasses deep venous thrombosis and pulmonary embolus, and is the proximate cause of death in over 100,000 hospitalized patients per year. This project will critically examine the pharmacokinetics of prophylactic doses of enoxaparin in surgical patients, and will evaluate how alteration of enoxaparin dose magnitude and frequency affects peak and trough aFXa levels as well as risk for re-operative hematoma. If subtherapeutic aFXa levels are observed, the study will design, implement and test a clinical protocol to optimize post-operative aFXa levels. Although not an explicit Aim, this study will also provide important preliminary data on VTE rates in surgical patients with in range and out of range aFXa levels.

Knee arthroscopy is the most commonly performed orthopaedic procedure worldwide, with, according to the American Society for Sports Medicine, over 4 million procedures performed each year. The risk of venous thrombosis following this procedure is considerable with rates of symptomatic events varying between 0.9% and 4.6%. It is currently unknown how this high risk comes about considering its short duration and minimal tissue damage caused by the procedure. A factor that may play a role is the use of a tourniquet. A large majority of orthopaedic surgeons prefer to operate within a 'dry field', which is obtained by the use of a tourniquet. Tourniquet applied surgery is not without risks. Although its use during orthopedic surgery is widely accepted and a standard procedure, tourniquet use can lead to loss of muscle functional strength and contractile speed, vessel wall damage and nerve injury, next to the possibly increased risk of venous thrombosis. In the proposed study the investigators will investigate the effect of a tourniquet on local and systemic markers of hypoxia, inflammation, involvement of endothelium, and coagulation activation. A finding of more prominent activation of the coagulation system with tourniquet use than with non-use will create an important opportunity to prevent thromboembolic events in these patients, as it has been shown that knee arthroscopy can be performed adequately without the use of a tourniquet. Furthermore, it will increase the understanding of the pathophysiology of thrombosis.
