All clinical trials

The goal is to compare the results observed in patients that had both an exercise oximetry and a thallium scintigraphy for lower limb claudication

Covid-19 has increased organizational tensions within health services (lack of resources, difficulties in recruiting healthcare professionals , elderly and polypathological patients, etc.) and tested the reliability of health facilities. This project aims to draw lessons so that hospitals can transform themselves while improving their reliability to face future crises and other exceptional situations. Research hypothesis: Crisis management arrangements lack sensitivity to uncertainty, which manifests itself in lower quality of care and efficiency losses for the entire institution. The virtuous practices implemented during the crisis spontaneously incorporated principles of the highly reliable organization. The integration of principles from complexity theory into the management of institutions promotes high reliability organization. Sustaining these virtuous practices in order to anticipate and cope with crises requires the activation of two interconnected levers: a shared vision (by patients, healthcare professionals, ARS, HAS, and the Ministry in the first place) of the meaning of the action taken by hospitals, and the development of a policy enabling hospitals to become both learning and highly reliable. Main objective: To evaluate the management process of the Covid-19 epidemic by the university hospitals of the Auvergne-Rhône-Alpes region, and the structures linked to them (establishments in their territory, ARS, user associations), in terms of points of improvement and good practices. This evaluation concerns the preparation, management and exit phases of the crisis.

Collecting data about the rare leukemic presentation of anaplastic lymphoma to study the characteristics of patients with leukemic phase of ALCL

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.

This is a prospective and observational clinical study for seeking out a better way to predict the pathologic complete response (pCR) in patients with advanced gastric cancer (AGC) based on the post-neoadjuvant treatment Magnetic Resonance Imaging (MRI) and CT data. This study will help the surgeons to better formulate treatment regimens for gastric cancer in the clinical practice.

The aim of the study is to assess the influence of high doses of intravenous corticosteroids on plasma inflammation and bone markers in patients with primary glomerular disease. The study would include 40 patients with chronic kidney disease. The main inclusion criterion is clinical and histopathological diagnosis of primary glomerular disease and urine protein excretion >2.0 g/24h. The exclusion criteria include secondary glomerular disease, acute kidney injury, acute or chronic inflammation, history of non-compliance.

Bronchiectasis is a chronic respiratory disease characterized by permanent bronchiectasis.The incidence and prevalence of bronchiectasis have assumed continuously grows in global. Different from overseas, bronchiectasis is common disease in China. This study will collect data from the real-world bronchiectasis database and follow up for one year, describe the bronchiectasis exacerbation rate and proportions for frequent exacerbation, clinical features and prognosis of bronchiectasis exacerbation, the treatment pattern (when clinically stable) during follow-up period; and describe characteristics of bronchiectasis at baseline. This study will also explore potential baseline risk factors for bronchiectasis exacerbation during follow-up period.

Through the analysis of the data of 8094 patients with knee meniscus injury before December 31, 2008 and more patients with partial meniscus resection, subtotal resection and total resection, we can understand the gender difference and ratio of medial and lateral meniscus injuries. Differences, differences in locations, differences in tearing methods, differences in surgical methods, and the course of the disease affect the meniscus injury and surgical methods, and further affect the patient's knee degeneration imaging, accompanying cartilage injury, knee osteoarthritis, Partial resection, subtotal resection and meniscus regeneration after total resection, imaging and secondary arthroscopic exploration (Second-Look) were studied.

Mediastinitis are rare but serious infections, with mortality rates varying from 6 to 30% according to the literature. They are essentially linked to surgical management (cardio-thoracic in particular), but some forms can be spontaneous, after extension of an ENT infectious focus, for example. Despite their seriousness, there is no strong recommendations to define their management, especially concerning antibiotic therapy and its duration. The aim of this research is to make a descriptive analysis of the cases of mediastinitis at HUS in recent years, and to study the therapeutic strategy used

Rectal cancer patients who received neoadjuvant chemoradiotherapy in Peking University Third Hospital in 2021 are divided into acute myelosuppression group, chronic myelosuppression group and normal group. The differences of magnetic resonance parameters between the groups were compared. The risk identification model of acute and chronic myelosuppression after neoadjuvant chemoradiotherapy was established by clinical risk factors and quantitative parameters of magnetic resonance imaging, and the prediction efficiency of the model was evaluated.
