Accuracy of the D-Dimer Assay for the Exclusion of Pulmonary Embolism in a High Risk Oncologic Population...
CancerPulmonary EmbolismThe purpose of this study is to see if a blood test (D-dimer) is as precise as the CT scan for the detection of clots. A pulmonary embolism is an obstruction of the blood vessels in your lungs usually due to a blood clot that travels to the lungs usually from the leg. Research has shown that the results of a specific blood test (D-dimer) can be used instead of a CT scan to diagnose clots. D-dimer is a valuable diagnostic marker in either detecting the presence of or monitoring the progress of blood clots. D-dimer assays have proven to be a beneficial diagnostic tool in the evaluation of patients with suspected pulmonary embolism (PE).
Risk Factors for Venous Thromboembolism
Deep Venous ThrombosisPulmonary EmbolismDeep venous thrombosis is the presence of blood clots, usually in the legs that lead to either local problems or breathing problems if the clot moves to the lungs. This study is designed to assess both clinical conditions as well as common genetic factors that lead to more risk of deep venous thrombosis. Clinical conditions of venous thrombosis include: stroke, malignancy, and situations such as surgery, pregnancy, trauma, or travel.
Registry of the Evolution of Diagnosed and/or Hospitalized Patients for Pulmonary Embolism During...
Pulmonary EmbolismThe purpose of the study COVID-EP is to classify all the complications occurring after the diagnosis of pulmonary embolism in patients tested initially COVID-19 positive and negative by RT-PCR (on nasopharyngeal sample) during the peak of the pandemic in France (April 2020). The patients will be followed for 1 year in order to provide clinical and paraclinical data not yet published in the literature. In order to secondarily confirm the COVID-19 status of initially negative COVID-19 patients (by RT-PCR), a serology test will be performed. The collected complications will then be compared between each of the 3 following groups: [PCR-COVID 19-Neg & Sero-COVID 19-Neg] versus [PCR-COVID 19-Neg & Sero-COVID 19-Pos] versus [PCR-COVID 19-Pos].
Hyperbaric Oxygen Therapy Registry
Air or Gas EmbolismCarbon Monoxide Poisoning13 moreThe purpose of the Hyperbaric Oxygen Therapy Registry (HBOTR) is to provide real world patient outcome and side effect information from electronic health records submitted to a specialty specific hyperbaric registry as part of "Stage 2 of Meaningful Use," including data provided to meet PQRS requirements via the registry's QCDR mission. Goals include understanding the value of HBOT among patients treated for a variety of conditions in relation to the frequency and severity of HBOT side effects. While randomized, controlled trials can establish the efficacy of treatments like HBOT, because they routinely exclude patients with co-morbid conditions common to those patients seen in usual clinical practice, the results of RCTs are usually non-generalizable. Real world data can be used to better understand the effectiveness of HBOT among typical patients, as well as the risks associated with treatment.

Examination of the Standardized Use of the Pulmonary Embolism SOP in the Clinical Routine of the...
Pulmonary EmbolismUsage of a guideline-compliant SOP in each chest pain unit (CPU) is instrumental in establishing the diagnosis of a pulmonary embolism without time delay. With the integration of this SOP as a "clinical decision tool" (CDT) into the electronic database of the CPU, the standardized application of the pulmonary embolism SOP in the clinical routine of the CPU will be tested using a retro- and prospective approach.
What Treatment for Patients With Phlebitis or Pulmonary Embolism ?
Venous Thrombosis or Pulmonary EmbolismThe objective of the "anticoagchoice" study is to analyze the preferences of people suffering from phlebitis, in terms of anticoagulant, to improve adherence to these treatments, to adapt the medical prescriptions.
COVID-19, bLOod Coagulation and Thrombosis
COVIDEmbolism and Thrombosis2 moreCoronavirus 2 (SARS-CoV2) has been identified as the pathogen responsible for severe acute respiratory syndrome associated with severe inflammatory syndrome and pneumonia (COVID-19). Haemostasis abnormalities have been shown to be associated with a poor prognosis in these patients with this pneumonia. In a Chinese series of 183 patients, the hemostasis balance including thrombin time, fibrinogenemia, fibrin degradation products and antithrombin III were within normal limits. Only the D-Dimer assay was positive in the whole cohort with an average rate of 0.66 µg / mL (normal <50 µg / mL). These hemostasis parameters were abnormal mainly in patients who died during their management; the levels of D-dimers and fibrin degradation products were significantly higher while the antithrombin III was reduced. The findings on the particular elevation of D-dimers in deceased patients as well as the significant increase in thrombin time were also reported in another series. Higher numbers of pulmonary embolisms have been reported in patients with severe form of SARS-COV2 (data in press). This research is based on the hypothesis that the existence of deep vein thrombosis (DVT) could make it possible to screen patients at risk of pulmonary embolism and to set up a curative anticoagulation. The main objective is to describe the prevalence of deep vein thrombosis in patients hospitalized in intensive care for acute respiratory failure linked to documented SARS-COV2 pneumonia, within 24 hours of their admission.
