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.
CFR has been studied for few years using 82 Rubidium PET (positron emission tomography) /CT. CFR has shown to be correlated with cardiovascular events occurring in the 10 following years. CFR also helps to identify multivessel coronary disease. Few studies have shown the possibility to calculate CFR during myocardial perfusion SPECT on new ultrafast CZT cameras.
This research aims to study the composition of the peritoneal exhaust gas during laparoscopic surgery to detect and possibly quantify the presence of air and / or N2O. This purely descriptive work is part of other experimental work that the investigators have already published.
This study aims to evaluate clinical and radiological outcomes of isthmic spondylolisthesis surgically treated with combined approach. The goal is to demonstrate that it is a safe and efficient technique to treat isthmic spondylolisthesis. There is very little literature concerning this procedure.
This study will evaluate if clazosentan (on top of normal routine medical care) can reduce the risk of developing complications related to cerebral vasospasm and permanent brain damage as compared to normal routine medical care alone.
The aim of this clinical trial is to provide information about autofluorescence of pathological versus healthy vocal folds tissues. Experimentations are performed on vocal folds biopsies obtained from patients, surgered at ENT department, university hospital of Besançon. After being extracted, samples of vocal folds are submitted to excitations at 365 nm, 405 nm and 450 nm; light spectral absorptions are measured, and results are compared to reference anatomopathology.
For several years, the French Addictovigilance Network (FAN) highlights potential problematic consumptions with zolpidem. To prevent abuse and misuse of zolpidem, the French Health Products Agency has changed the regulatory framework of zolpidem prescription. Thus, since the 10th of April 2017 zolpidem prescriptions have to be secured (particular support, dosage written out). The investigators hypothesized that this change will affect zolpidem consumption but also the consumption of all sedative drugs. In order to assess the incidence of the regulatory change for zolpidem prescription the investigators conduct a two part study: an epidemiological study with French National Health Insurance Fund for Employees database and an observational study with general practitioners and zolpidem consumers.
To observe the continued performance of the Medtronic Resolute Onyx™ Zotarolimus-Eluting Coronary Stent System in a real-world more-comer population. To collect data on the safety and efficacy of the Medtronic Resolute Onyx™ Zotarolimus-Eluting Coronary Stent System in bifurcated lesions.
Changes in microbiome have been reported recently in psoriasis lesions compared to healthy surround skin. Preliminary data showed that systemic treatments of psoriasis induce modification of the skin microbiome that becomes similar to healthy individuals after successful treatment. The causative role of microbiome in psoriasis remains in debate. The modification of skin microbiome is suspected to be able to activate the innate immune response, namely natural killers (NKs) and immune lymphoid cells (ILCs). Three types of ILCs have been reported. ILC1 (immune lymphoid cells1) that trigger a Th1 response, ILC2 (immune lymphoid cells 2) that stimulate Th2 response and ILC3 (immune lymphoid cells 3) that induce Th17 response. Interestingly, ILC2 have been reported to be increased in atopic dermatitis while ILC3 are increased in psoriasis.
This study will evaluate the efficacy and safety of a FDC of imipenem/cilastatin (IMI) and relebactam (REL) [IMI/REL, MK-7655A] compared to piperacillin/tazobactam (PIP/TAZ) in the treatment of adults diagnosed with Hospital-Acquired Bacterial Pneumonia (HABP) or Ventilator-Associated Bacterial Pneumonia (VABP). The primary hypothesis is that IMI/REL is non-inferior to PIP/TAZ as measured by the incidence rate of all-cause mortality through Day 28 post-randomization.
Muscle wasting is present in almost 50% of patients treated with chronic hemodialysis. It is associated with an increased risk of death (particularly from cardiovascular causes) and compromises quality of life (loss of autonomy and fatigue). The mechanisms leading to muscle wasting in chronic kidney disease have been the subject of several studies in animals. These have highlighted the role of the ubiquitin-proteasome system (UPS). Activation of UPS during chronic kidney disease is multifactorial. It is the result of resistance to the action of insulin/IGF1, metabolic acidosis, low grade prolonged inflammation and increased production of myostatin. To date few studies have been conducted in humans. The investigators want to identify blood markers related to muscle protein breakdown in patients undergoing hemodialysis. In parallel, the investigators want to adress the mechanisms involved in muscle proteolysis. In addition, the investigators want to identify the proteins degraded and the ubiquitination enzymes (E2/E3 couples) specifically involved in muscle loss during hemodialysis. Muscle biopsies and blood sample will beperformed during scheduled surgeries in healthy volunteers (negative control), cancer patients (positive control) or undergoing chronic hemodialysis. RNA seq analysis will be performed in blood samples and proteomic mass spectrometry analysis for establishing a specific profile between muscle and blood markers. A limited subset of blood markers common to cancer and hemodialysis atrophying muscles will be used for elaborating a chip dedicated to early detect an atrophying process. Thus, the investigators will first design a diagnostic tool for detecting non-invasively muscle protein breakdown before the onset of muscle atrophy. This will enable early and efficient nutritional counter-measures.
