Filter by:DESTINY D-Dimer is an observational feasibility study, and a collaboration between the University of South Wales and Cwm Taf Morgannwg University Health Board (CTMUHB). The study is based at St. John's Medical Practice in Aberdare, where participant recruitment will take place. Blood D-dimer data will be collected from CTMUHB Pathology Laboratory services, at Prince Charles Hospital. Study blood samples will be obtained by the research student, LAH, under the direction of Dr Owen Thomas at St John's Medical Centre. The participant data will be collected by the research student who will conduct a Wells' Risk Score and perform D-dimer POC tests to generate quantitative data. Data will later be compared by the research student with the diagnoses obtained from Secondary Care at Prince Charles Hospital via analysis of medical records to include a laboratory generated D-Dimer results and additional diagnostics (eg. Doppler). A laboratory based analytical verification of D-dimer POC tests will be undertaken to compare with the current laboratory method. The study will compare the data from the D-dimer POC tests and those gained using laboratory methods at Prince Charles Hospital.
This study evaluates the risks and experience of blood clots and bleeding in patients with blood cancers. While it is standard of care to use medications to reduce the risk of blood clots in hospitalized individuals, some patients with blood cancers have low platelet counts that can increase the concern for bleeding complications associated with these medications. At this time, the optimal management strategies for blood clots are not well known for patients with blood cancers. This pilot study evaluates additional information that could help doctors know which patients are at highest risk for blood clots.
This clinical trial is designed to evaluate if the periodic screening for deep venous thrombosis by ultrasound of lower extremity in patients with intensive care unit (ICU) patients with COVID 19 impacts on mortality, ICU stay and total length of stay in the hospital, along with other outcomes.
Background: venous thromboembolism (VTE) is a common complication in critically ill patients, admitted to the Intensive Care Units (ICUs). At the present time, there is no validated score to estimate risks and benefits of antithrombotic pharmacological prophylaxis in this subset of patients. Aim of the study: investigating potential harms and benefits of a protocol for systematic screening of DVT in critically ill patients, admitted to an ICU. Expected relevance: systematic screening for deep vein thrombosis (DVT) through ultrasound (US) lower limb veins examination could help defining the indication to antithrombotic pharmacological treatment, but no protocol of systematic screening has been validated so far. Furthermore, the screening could be associated with over-diagnosis and consequent over-treatment, as well as increased management burden for the caregivers and higher healthcare costs.
The objective of this study is to demonstrate the safety and efficacy of the Indigo Aspiration system for percutaneous mechanical thrombectomy in a population presenting with obstruction due to deep vein thrombosis (DVT) who are eligible for treatment.
Isolated distal DVT (iDDVT) is the most frequent clinical presentation of VTE and is associated with a significant morbidity and risks of long-term complications. Data from clinical trials highlighted that patients with iDDVT might require some level of AC treatment. However, the optimal anticoagulant intensity is uncertain, and it is plausible that the best benefit/risk ratio for AC might be achieved with lower intensity doses rather than therapeutic doses. The principal research question of the Apixaban to treat calf vein thrombosis (API-CALF) study is to determine whether, after a conventional course of 7 days of Apixaban 10mg BID, Apixaban 2.5mg BID (experimental arm) is non inferior to Apixaban 5 mg BID (standard arm) in preventing VTE recurrence and bleeding in patients with iDDVT. Patients will be treated with Apixaban for a total of 3 months. In that perspective we will conduct an international multicentre open-label assessor-blinded study
This study aims to investigate the incidence of venous thromboembolism in people who are diagnosed with atopic dermatitis.
Compression ultrasound is commonly used in emergency department. Accuracy to rule out deep vein thrombosis is excellent but lower then Ddimer assessment which is actually gold standard. With progress in formation of emergency physicians (EP), quality of material used, the investigators hypothesize that compression ultrasound can rule out deep vein thrombosis in case of non high probability, as standard care and DDimer assay.
If deep vein thrombosis (DVT) is suspected among patients who have symptoms such as pain or swelling of the lower extremities, duplex ultrasound of the lower limb is the first-line imaging modality to diagnose DVT. However, duplex ultrasound is time consuming, requires patient transport to a diagnostic imaging facility. In recent years, abbereviated bedside ultrasound technique has been accepted by emergency physician to diagnose the presence of DVT. Several studies have proven that the accuracy of this abbreviated bedsude ultrasound for assessing the presence of deep vein thrombosis is not inferior to experts, but how much ultrasound experience is required to obtain the accuracy that does not inferior to experts has yet to be studied. The aim of this study is to identify how much learning by emergency physicians is needed to obtain the accuracy of the lower extremity ultrasound examination comparable to that of experts.
The overall goal of the VVIRTUOSO study is to determine the incidence of VTE including symptomatic DVT and PE after hospital discharge in patients with COVID-19 by implementing a pragmatic patient-centred prospective virtual VTE monitoring program in Canada and the United States.
