Active clinical trials for "Thrombosis"

The proposed PIVOTAL study will examine a panel of platelet/coagulation activity markers during the perioperative period. The goal is to develop a clinically useful assessment of platelet/coagulation activity for risk stratification that may ultimately serve as a target for therapeutic intervention. This study will enroll 200 patients with peripheral artery disease undergoing vascular surgery. PIVOTAL is funded by American Heart Association and is scheduled to begin enrollment in July 2013 for approximately two years.

The study aims to document the flow of German patients with cancer and acute deep vein thrombosis from first visit to diagnosis and treatment, the applied diagnostic procedures, and therapy modalities.

Central venous catheters are frequently used for monitoring haemodynamic status and rapidly delivering fluid therapy during the peri- and postoperative periods. Indwelling central venous catheters are typically used 7-14 days postoperatively for additional monitoring and treatment, but patients may develop asymptomatic catheter-related thrombosis, leading to life-threatening pulmonary embolism and death. Early detection helps to avoid such complications. This prospective observational study investigated the risk factors associated with catheter-related right internal jugular vein thrombosis in pediatric patients. The study enrolled 80 pediatric patients who were scheduled to receive central venous catheter. To detect thrombus formation, Doppler ultrasound examinations from the thyroid cartilage level to the supraclavicular region were used after CVC placement and on each of the following days until the catheter was removed.

Vascular complications in patients with inflammatory bowel disease (IBD), comprising mainly Crohn's disease (CD) and ulcerative colitis (UC), representing 2% extra-intestinal complications. In over 60% of cases, these vascular complications of deep venous thrombosis (DVT) or pulmonary embolism (PE). Several studies have shown that patients with IBD have a risk of venous thromboembolic disease (VTE) increased from 1.5 to 3.5. This risk is closely related to disease activity.

Pharmacists are in the best position to counsel and educate patients on anticoagulant agents such as NOACs. This should enable patients to play a more active role in their treatment and ultimately enhance adherence behaviour. However, educational elements should be targeted to knowledge. Thus, the investigators will develop and validate a questionnaire that can assess knowledge about NOACs

This study investigates electrical acupoint stimulation (EAS) administered in peri-operation for improving postoperative recovery in elder patients, who accept knee arthroplasty. the surgery cause to change of stress response, which might be associated with postoperative recovery of patient Totally, three groups are created, 1/3 participants receive transcutaneous electrical acupoint stimulation, 1/3 participants receive electroacupuncture, the rest 1/3 will use sham transcutaneous electrical acupoint stimulation.

The study will assess the distribution and variability of whole blood clotting time (WBCT) measurement in human blood collected from healthy volunteers that is untreated and spiked with predetermined concentrations of edoxaban or enoxaparin.

Many clinical trials show that 30 to 50 % of the hospitalized patients are undernourished in various degrees. This prevalence didn't change since 15-20 years The fact is that the present undernutrition in the admission deteriorates during the hospitalization. Besides, the cerebral vascular accident (AVC) complicates the first days, in at least 50 % of the cases, the disorders of the gulp, which are a risk factor of acquired undernutrition. The nutrition holds an important place in the therapeutic coverage of the AVC. Nevertheless, the link between the undernutrition the entrance and the evolution of the AVC is at the moment only little known. The purpose is to study the impact of the undernutrition in the entrance to the hospital (undernutrition previous to the AVC), on the gravity and the evolution

The RETORIC study is a prospective cohort study with a primary aim to assess the incidence and independent predictors of reduced leaflet motion and valve thrombosis after TAVI procedure using multimodality imaging strategy comprising cardiac CT, transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE). As a secondary aim we will assess the incidence of stroke and transient ischemic attack (TIA) in patients with reduced leaflet motion and/or thrombosis when compared with those with normal leaflet function. In addition we will randomize patients with reduced leaflet motion and/or valve thrombosis to single antiplatelet therapy plus oral anticoagulation therapy versus standard therapy. The primary outcome of the nested randomized trial will be the presence of reduced leaflet motion and/or valve thrombosis after 4 months, the secondary outcome is the presence of ischemic changes in brain demonstrated by MRI.

Despite of preventive measures, the incidence of deep venous thrombosis (DVT) in ICU patients is estimated to range from 5-31%. While clinical diagnostics is unreliable, ultrasound compression test (UCT) has proven to be a highly sensitive and specific modality for the recognition of lower extremity DVT. Delegating this competence to ICU nurses can increase UCT availability and enable preventive DVT screening. Therefore, the investigators decided to conduct a clinical study to evaluate the sensitivity and specificity of UCT performed by general ICU nurse in ICU patients compared to an investigation by ICU physician certified in ultrasound. Prior to the study, each nurse-investigator participating in the study undergo one-hour training in UCT and examine 5 patients under supervision. Then, ICU patients without known DVT will be investigated by UCT in the femoral and popliteal region of both lower extremities by trained general ICU nurse-investigators. On the same day, the examination will be repeated by an ICU physician-investigator. The results of the examinations of each patient will be blinded to each other for both investigators until both tests are performed. The sensitivity and specificity of the test performed by general nurse will be calculated in comparison with the examination by a specialist.
