Filter by:Central venous (CVC) is essential in modern healthcare but unfortunately associated with complications, including thrombosis. In a recently published study, it was showed that 12 out of 12 deceased patients had subclinical CVK-related thrombosis (Rockholt et al.). To shed light on this problem, the current studies were designed. In sub-study 1, deceased patients with CVC who are referred for clinical autopsy are included. Before the autopsy, the deceased will be examined with a photon-counting computed tomography (CT) scan and the results will be compared. In sub-study 2, living patients with CVC who are referred for various CT scans without contrast, are included. After informed consent, the patient will be examined with the photon-counting CT, whose reliability has been validated in Part 1 and the incidence of subclinical CVC-related thrombosis will be reported.
The aim of the study isto evaluate the inter-observer reliability of the assessment of venous thromboembolic risk using the TRiP(cast) score in patients presenting with trauma to a lower limb requiring immobilisation, and of the clinicians' assessment using the physician's implicit probability (gestalt) compared with the use of the TRiP(cast) score.
Intimate violence against individuals, which is particularly marked among women, is one of the most widespread human rights violations in the world. The Women Abuse Screening Tool (WAST) self-questionnaire is a screening tool validated in French. Our preliminary data describing the association between intimate violence against women and the first attack of unexplained venous thromboembolic disease, show a significant frequency of positive responses to the WAST among women attending a biological hematology consultation at the CHU de Nîmes, for reasons of hemostasis disorders (8% out of the first 200 cases). The study authors wish to establish the prevalence of this situation among patients presenting to the CHU de Nîmes for hematological exploration and management. They hypothesize that the prevalence of violence against individuals seen in Hematology consultations is higher among individuals with hemostasis pathologies (hemorrhagic and thrombotic pathologies) than those with cellular pathologies, and higher among women than men.
The purpose of this research is to collect information about how the RevCore Thrombectomy Catheter works to treat stent blockages.
The investigators are studying whether treatment with a proton pump inhibitor called omeprazole reduces gastrointestinal bleeding in older adults taking blood thinners for a blood clot (venous thromboembolism). The purpose of this study, a pilot study or a feasibility study, is to test the study plan and determine whether enough participants will join a larger study and accept the study procedures.
Venous thromboembolic disease (VTE) is a common (1/1000), potentially serious disease (10% mortality when the clinical presentation is that of pulmonary embolism (PE)). In cancer patients, the risk of developing VTE is high and constitutes a negative prognostic factor for cancer; the risk of bleeding is also increased. The study of VTE in the context of cancer is a major challenge, given the frequency of the association, the heterogeneity of the situations, the risk factors involved and the therapeutic issues in both curative and primary prevention; in this field, many uncertainties remain, justifying a study focused on the association of VTE and cancer.
The Rhea-study is a multicenter prospective diagnostic proof-of-concept study There is an unquestionable need for improved diagnostic approaches for (incidental) SVT. The researchers plan to evaluate the MRDTI technique, that has been shown to be accurate in other settings of difficult-to-diagnosis venous thrombosis, for the notoriously challenging diagnosis of incidental SVT. This study targets an important unmet need and will provide the basis for precision medicine for patients with SVT in the near future, i.e. the possibility of assessment of the age of the thrombus in patients with incidental SVT, which is of utmost importance for determination of the indication for anticoagulant therapy. If this hypothesis is proven true, i.e. sensitivity of MRDTI for SVT is indeed >90%, the investigators will proceed with performing a randomized controlled outcome study in which patients with possible/probable chronic SVT with normal MRDTI test results and no other indications for anticoagulant therapy. These patients will be randomized between active therapeutically dosed anticoagulation versus no anticoagulation, to compare clinical outcome with regard to the occurrence of venous thromboembolism and/or Progressive symptomatic SVT as well as major bleeding.
This is a single-center, single-arm, open-label study that includes patients meeting the inclusion criteria (liver-GTV volume < 700ml or estimated liver-GTV V5 < 300ml) with hepatocellular carcinoma with diffuse tumor thrombosis involving both left and right lobes. All lesions receive moderate-dose hypofractionated intensity-modulated radiotherapy, with a gross tumor dose of 25Gy/5f, and a maximum dose of 35Gy/5f at the tumor center. One week before or during the radiotherapy, patients receive concurrent Pembrolizumab at a dose of 200mg. Subsequently, Pembrolizumab is administered intravenously every 3 weeks. Follow-up examinations are conducted 1-3 months post-radiotherapy. Lenvatinib 4mg may be used for maintenance therapy with Pembrolizumab if there are no contraindications. Maintenance therapy is continued until disease progression or intolerance. The primary endpoint is median overall survival (mOS), and secondary endpoints include objective response rate (ORR), progression-free survival (PFS), and toxicity.
Pulmonary embolism, the second leading cause of death in cancer patients, is effectively treated with anticoagulants. In patients with cancer-associated thrombosis (CAT), the use of anticoagulants is associated with 10 to 15% of bleeding in the first 6 months. Most of the guidelines propose to integrate the bleeding risk in the choice of therapies. Thrombin generation assay (TGA) reflects an overall hemostatic response and could be a useful biomarker. Proven on the thrombotic side in the CAT population, useful in the assessment of the bleeding risk of hemophiliac patients, the TGA is emerging as a tool. The investigators to measure TGA in cancer patients included prospectively, having recently developed a CAT and to evaluate the association between the measurement and the risk of hemorrhagic complication under anticoagulant during the first 6 month of treatment.
This is a cohort study collecting patients with head and neck cancer who underwent free flap surgery at a single medical center between January 2019 and January 2022.
