The main goal of this study is to evaluate the additional value of EEG-fMRI method in the presurgical evaluation of focal intractable epilepsy. To consider a patient for surgery, the main difficulty is to define accurately the epileptogenic zone. This definition is complex and is often supported by several types of exploration (MRI, FDG PET, neuropsychological testing, video-EEG...). In this study we will evaluate the adding value of the simultaneous recording of EEG and fMRI in the epileptogenic zone definition.
Primary objective Demonstrate functional markers derived from electrophysiological signals recorded during cognitive tests. These markers should make it possible to optimize the targeting procedures of electrode implantation sites for a better effectiveness of deep brain stimulation therapy. Research hypotheses The mechanisms of action of the deep brain stimulation (DBS) involve the modulation of the activity, locally and on a large scale, of functional cortical-subcortical networks showing pathological behavior beforehand. The electrophysiological measurements in response to different tasks make it possible to highlight precise dysfunctions of these neural networks, in relation with the behavioral and / or motor disorders associated with the pathologies treated by DBS. Consequently, we hypothesize that the exploitation of electrophysiological responses during cognitive or sensorimotor tasks performed during the implantation procedure of stimulation electrodes in patients treated with DBS will allow : - To collect fundamental data to understanding the physiological functioning of basal ganglia in humans ; - To collect functional markers from the operating room in relation to the symptoms targeted by the DBS that will help in the choice of implantation site of the stimulation electrode ; - Define long-term predictive markers of DBS effects by comparing electrophysiological effects measured post-operatively and clinical scores under DBS.
Pulmonary Embolism (PE) is a frequent and severe disease with an annual incidence of about 75000 cases in France and a short-term mortality rate of about 10%. Death is usually related to an acute right ventricular (RV) failure due to the increase in right ventricular afterload. Treatment of PE with RV failure consists in fluid expansion and thrombolysis in case of shock. However several studies suggest that fluid expansion may worsen acute RV failure by increasing RV dilatation and ischemia and left ventricular compression by RV dilatation. Thus, current guidelines regarding PE treatment remain unclear about the use of fluid expansion. In a preliminary study published by our group, we showed that diuretic treatment in the setting of PE with RV dilatation is safe and is associated with an increase in urine output, a decrease in heart rate and an increase in SpO2 in normotensive patients with oliguria. This may be related to the decrease of ventricular interdependence and enhancement of both LV and RV function. The main objective of the study is to evaluate the 24-hours clinical benefit of furosemide in patients referred for acute PE with RV dilatation compared to placebo. The combination of urine output and sPESI clinical parameters reflects hemodynamic status. It is relevant as it indicates the disappearance of pre-shock symptoms and is therefore associated with a lower event risk. Thus, it allows early discharge of the patients from the intensive care unit.
Background: - Researchers want to find better ways to treat cancer. One drug that treats cancer is paclitaxel. Sometimes proteins block that drug from working. Researchers want to see if another drug, nilotinib, helps paclitaxel work better. Objective: - To test the safety of nilotinib plus paclitaxel and find out what doses of the drugs can be given safely to people. Eligibility: - Adults at least 18 years old with advanced cancer that has progressed after receiving standard treatment, or for which no effective therapy exists. Design: - Participants will be screened with tests they usually get in their cancer care: medical history, physical exam, blood and urine tests, heart test, and scans. - Participants will take the two study drugs in 28-day cycles. They will keep a medicine diary. - Nilotinib will be taken by mouth twice every day except day 1 of the first cycle. - Paclitaxel will be given by IV once a week for the first 3 weeks of a cycle. This will usually be done at the clinic. - Most participants will have a weekly study visit every week for cycle 1, then the first 3 weeks of other cycles. They will have: - Physical exam at every visit. - Blood tests multiple times for cycle 1, then the first 3 weeks of other cycles. - Scans every 8 weeks. These may be CT or MRI scans, in a machine that takes pictures. Or they may be ultrasounds, where a wand is pressed on the skin with gel on it. - Around 30 days after stopping the study drugs, participants will be called to discuss any side effects.
We will include patients with EV and EVB. They will be randomized to EVL vs. NSBB for primary prevention And EVL+long-term NSBB vs. EVL+short-term NSBB for secondary prevention. 150 patients will be included in a 3-year period. Primary end-points are formation/progression of ascites, acute kidney injury and survival. The other outcomes such as bleeding, rebleeding, infection and other risk factors will be also analyzed.
Endometriosis is associated with different types of pain (acute, chronic, excess nociception, neuropathic) generated by different mechanisms in the nervous system. The rTMS could provide significant analgesia for refractory endometriosis pain. The aim of the study is to evaluate the feasibility of transcranial magnetic stimulation (rTMS) for analgesia on chronic refractory endometriosis pain.
Patients with stage I non-small cell lung cancer have been historically treated with surgery whenever they are fit for an operation. However, an alternative treatment known as stereotactic radiotherapy now appears to offer an equally effective alternative. Doctors believe both are good treatments and are therefore conducting this study to determine if one may be possibly better than the other.
This project is aimed to assess the responsiveness of the Glittre ADL-test and the 1-Minute Sit-to-Stand test (1-Minute STST) to acute bronchodilation in patients with COPD. We also aim to investigate the physiological and perceptual response to bronchodilation of the Glittre ADL-test and the 1-minute STST. The specific objectives are 1)To measure the changes in time for completion of the Glittre ADL-test and the number of standing up during the 1-minute STST induced by a single dose of nebulized ipratropium bromide/salbutamol sulfate against those induced by a placebo in patients with moderate to severe COPD and 2)To compare in patients with moderate to severe COPD the CR (minute ventilation (VE), oxygen uptake (VO2), carbon dioxide production (VCO2) and heart rate) and symptomatic (dyspnea and leg fatigue perception) responses during the Glittre ADL-test and the 1-Minute STST following a single dose of ipratropium bromide/salbutamol sulfate or placebo. We suppose among others that the Glittre test completion time will be lesser, that the number of repetitions in the 1-Minute STST will be higher and symptoms intensity will be lesser among patients with COPD receiving bronchodilators.
This is an open label, dose-seeking phase 1/2 study using escalating doses of TRABECTEDIN given intravenously with defined doses of IPILIMUMAB and NIVOLUMAB based on preliminary results of the Checkmate 012 trial for NSCLC (Hellman et al., 2016). For the Phase 1 Part of Study, only previously treated patients will be enrolled. For the Phase 2 Part of Study, previously untreated patients will be enrolled.
The project will consist of a multicentre, prospective, observational study with a total duration of 24 months. Clinical, endoscopic and ultrasound data will be collected in a dedicated database (on IG-IBD Register), which will be used to identify potential clinical, endoscopic and ultrasound risk factors of re-operation. These data could be merged into a shared score, to stratify patients according to the risk of post-surgical re- operation and to define an optimal therapeutic management in the post- operative period. Approximately 220 adult patients, with a defined diagnosis of CD, who underwent a surgery for CD in the previous 6 months will be enrolled.
