There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Esophagectomy is the cornerstone of the curative treatment of esophageal carcinoma. Despite this treatment, patients can suffer from locoregional or distant metastatic disease and only a very selected group of patients can be cured: mostly those with recurrence in one single organ. Brain metastases are rare after esophagectomy for cancer, but they have a serious impact on survival. Agressive treatment is often moren difficult for brain metastases compared to other metastases and some risk factors have been identified earlier. There is an impression that the incidence of brain metastases in esophageal cancer patients has increased since the introduction of neoadjuvant treatment schemes. However, this is not clear yet. A potential explanation could be that chemotherapy disturbs the blood-brain-barrier, hereby facilitating the migration of tumor cells to the brain. The purpose of this study is to retrospectively analyze the incidence and potential risk factors of brain metastases in patients who underwent esophagectomy for esophageal cancer. Patients treated between 2000 and 2019 will be included and outcome parameters are Odds Ratio for brain metastases (comparison between primary surgery and neoadjuvant treatment followed by surgery), time to recurrence and risk factors, number and characteristics of the brain metastases.
Perioperative hypersensitivity reactions are still associated with significant morbidity and mortality despite early recognition and use of epinephrine. The epidemiology of these reactions evolves over time and changes with clinical practice. The main objective is to study the epidemiology of these reactions over a 10-year period, including patient phenotype, reaction phenotype and outcome of the allergic work-up.
Prostate cancer is the first cancer amongst men with more than 50000 cases per year in France. Surgical, radiation, frost, or ultrasound induced rectourethral fistula is a rare complication (<1%) of localized prostatic cancer treatment but hard to manage. Different types of treatment exist: conservatory, trans-sphinteric (York-Masson), transanal, perineal, with or without muscle flap interposition. Gracilis flap interposition for rectourethral fistula management is a promising technique but few cases are described and functional results are scarce. The aim of this study is to present surgical and functional outcomes of rectourethral fistulas surgery with gracilis flap interposition after treatment of localized prostate cancer.
- Objective: Our study aims to evaluate the effectiveness of the "STOP" (Sevrage Tabagique à l'aide d'Outils dédiés selon la Préférence: Smoking Cessation using preference-based tools) intervention, a preference-based smoking cessation intervention for smokers with low socio-economic position (SEP). - Methods : STOP is a randomised, multi-centre, single blinded, intent-to-treat trial. Participating centres include primary care practices (community, municipal or general health clinics), hospital-based facilities, and healthcare institutions specialised in addiction treatment. Smokers with low SEP will be randomised into either the intervention or control group. Persons randomised to the control group will be accompanied by their health professional according to standard practice. Participants randomised to the intervention group will receive the same smoking cessation advice, drug (varenicline, champix,..) prescription and support as participants in the control group, but they will also have a choice of being given free Nicotine Replacement Therapy (NRT) (transdermal patch, gum, spray, inhaler, sublingual tablets/lozenges) and/or an electronic cigarette + e-liquid on the spot to aid their quit attempt. Follow-up appointments will take place at around 7 to 14 days, 1 month, 3 months and 6 months after inclusion, according to the participant and health professional availability. The main outcome measure of this study will be the 7-day point prevalence tobacco abstinence at 6 months after inclusion (yes/no), defined as self-reported abstinence for at least 7 days, This self-reported abstinence will be validated by measured exhaled carbon monoxide, unless this measurement is unavailable due to the ongoing covid-19 pandemic.
LASIK is a refractive surgery technique widely used in France. Postoperatively, the classic treatment after LASIK consists of instilling drops to reduce dry eyes. REPADROP® is an innovative eye drops stimulating corneal innervation. To date no study has quantified the improvement in dry eye syndrome and thus the quality of life of patients using REPADROP®.
COVID19 pandemic and SARS-CoV-2 rapid progression worldwide are already historical landmarks of the 21st century owing to the magnitude of the event and the collective response that populations have adopted to face such threat. This menace has imposed an unprecedented reactivity to promptly deliver answers in various fields and specifically in termes of diagnostic capabilities. The very first tests to be used were based on PCR reactions and on deep nasopharyngeal sampling. But this has shown to be insufficient to prevent contaminations and limit the progression of the disease. This approach requires important infrastructure thus limiting the extent to which it can be delivered. Moreover, nasopharyngeal swab is highly intrusive and therefore is not suitable for repeated testing of asymptomatic patients in surveillance programs. Actual need is based on new tests offering new capabilities both in terms of wide range availability, ease of use and reduced time-to-result duration. Such tests, affordable and that can be performed outside the lab would ultimately relief pressure on healthcare workers and laboratory facilities as well as help test massively wide range of populations thus limiting viral dissemination Such innovating test device has been developped by the start-up "Grapheal" and the present study will ultimately demonstrate the feasibility of COVID-19 diagnostic using this test.
To evaluate the prevalence of SARS-CoV-2 genome in patients with asymptomatic and moderately symptomatic COVID19.
Measuring bedside occlusion pressure in neurosurgical or surgical critically ill patients could tell us about the patient's respiratory drive, and therefore, tell us whether or not extubation will be successful.
Pulmonary embolism is a common cardiovascular disease and thoracic CT angiography is currently considered the gold standard for its non-invasive diagnosis. However, the diagnostic performance of CT angiography can be hampered by an insufficient enhancement of pulmonary arteries. Contrast Enhancement Boost (CE Boost) is a post-processing technique using an iodine density map to artificially improve pulmonary artery enhancement. This retrospective study compares standard CT-angiography images with CE Boost images to assess the potential improvement of diagnostic performance for the detection of pulmonary embolism.
We propose to set up a prospective randomized controlled trial to control the security and assess the efficacy of adjuvant treatment by rheopheresis in necrotizing-ulcered calciphylaxis in the hemodialysis population.
