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.
This study compares automated administration of propofol and remifentanil guided by the Bispectral index (BIS) versus manual administration for sedation after cardiac surgery.
Patients with C5 or C6 tetraplegia have paralysis of the triceps brachii. Elbow extension can be surgically restored by transferring the tendon from a preserved muscle onto the tendon of the paralyzed triceps brachii. The most frequently used method transfers the posterior deltoid tendon. However, transferring the posterior deltoid can create an imbalance in the shoulder joint and this technique is not recommended when the clavicular head of the pectoralis major is weak. In such cases, a preferred method is a biceps brachii tendon transfer. The success of this intervention relies on the ability of the patient to dissociate the drive between the transferred biceps brachii and the other elbow flexor muscles. Even though tendon transfers are widely used, the subsequent reorganization of muscle coordination strategies remains largely unknown. The identification of muscle synergies and co-coactivations from electromyography (EMG) signals, defined as groups of muscles activated in synchrony, may help to provide a deeper understanding of changes in muscle coordination. The objective of this study is to investigate for the first time the reorganization of muscle coordination after surgical restoration of elbow extension through the identification of muscle synergies and the quantification of muscle co-activations. Four participants with tetraplegia will take part to this study. The experimental procedure will be conducted before their surgery and once a month during 6 months after their surgery. The procedure consists of performing consecutive elbow extension-flexion cycles with the shoulder abducted at different angles. Surface and intramuscular EMG measurements will be collected for several upper limb muscles. Muscle synergies and co-activations will be extracted from the EMG measurements.
This trial is designed to evaluate QPI-1002 versus placebo for the prevention of Major Adverse Kidney Events (MAKE) in subjects at high risk for acute kidney injury following cardiac surgery. Half of the participants will receive QPI-1002 while the other half will receive placebo.
Nivolumab is superior to docetaxel monotherapy as second line treatment in advanced stage non-small cell lung cancer (NSCLC) patients. However, the long term survival advantage seems to be limited to a 20% proportion of treated patients. To date, no definitive biomarker, including tumor cells or infiltrative cells PD-L1 expression, has been demonstrated to predict nivolumab (or other PD1 or PD-L1 inhibitors) efficacy. Ipilimumab has also suggested efficacy in the same patient population. Finally, the addition of ipilimumab to nivolumab has a suggested better efficacy over nivolumab alone in advanced stage NSCLC patients with an acceptable safety profile. In parallel, hypo-fractionated radiotherapy alone has been suggested to elicit the immune system activity as demonstrated by the occurrence of an abscopal effect. Some case reports in melanoma but also lung cancer patients reinforced this hypothesis. Furthermore, preclinical and clinical data suggest that radiation may have a synergistic effect with antibodies targeting the immune checkpoints (PD1, PD-L1, CTLA4) and improve antitumor efficacy. Moreover, it has been shown that fractionated radiotherapy delivered in combination with aPD-1 or aPD-L1 mAbs is able to generate efficacious CD8þ T-cell responses that will in turn improve local tumor control, long-term survival, and protection against tumor rechallenge. Therefore, the combination of single fraction or hypo-fractionated radiotherapy with the anti PD1 nivolumab and/or the anti CTLA4 ipilimumab warrants further investigation. However, a large number of doses, sequences and schedules remain possible. In order to select the best combination, a mathematical modeling of immunotherapy in cancer and its synergy with radiotherapy has been set up. This work provides with mathematical formulas to link the drug serum concentrations of nivolumab and ipilimumab, and the dose of radiation therapy, to the immune response. In silico, the single and three fractions schedule have been found to have the same efficacy while activation of the immune response seems to be better using a hypo-fractionated (less than 6 fractions) radiotherapy in vivo.
Getting a consultation with a psychiatrist within an appropriate time is one of the main issues reported by general practitioners (GP) for patients suffering from mental disorders in primary care. Consultation liaison in psychiatry is a system focused on general medicine-psychiatry collaboration. The aim of the present study is to evaluate the impact of the consultation-liaison on the adequacy of the access time to a psychiatric consultation according to the degree of urgency evaluated by the GP.
Bipolar disorder is a severe psychiatric illness with chronic course and it is associated with high risk of relapse and hospitalisation, and many patients do not recover to their previous psychosocial functioning. Major reasons for poor outcomes are delayed intervention for prodromal mood and behavioural symptoms as well as incomplete treatment responses. Current diagnostic approaches used to assess mood symptoms rely on symptom-based categories, which lack sensitivity to detect subtle mood and behavioural changes. Therefore, the ability to better characterizing bipolar patients may allow to detect possible differences in the illness activity. On the other hand, there is a growing interest in the potential use of mobile technologies such as mobile apps, smartphone and internet in psychiatric care. Some projects have been testing the potential benefits of mobile apps to assess and treat individuals at-risk or suffering from mood and bipolar disorders, using online signs and symptoms monitoring, yet to the investigators knowledge, none of them have integrated a dimensional approach in a smartphone app to assess mood and behavioural alterations and bipolar illness activity, including subjective and objective data (e.g. physical activity, social activity, etc.). In this feasibility study the investigators will evaluate the potential relevance of Toi Même app to self-monitoring mood and behavioural changes in bipolar patients with different mood phases compared to the gold-standard mood rating tools used in clinical practice. All patients will be followed for 3 months, with outcome assessments after 2 weeks, after 1 month, 2 months and after 3 months.
Investigator seek to determine whether the volume of the liver can predict the survival after a decompensation of a patient suffering from chronic liver disease caused by excessive alcohol consumption (or alcoholic cirrhosis). Our hypothesis is that patients with a "small" liver have a lower survival compared to patients having a "normal" sized liver.
The primary objective of this study is to study the safety and efficacy of the BiOSS LIM C with respect to Patient oriented Composite Endpoint (PoCE) at 12 months in a "real world" left-main bifurcation population and as compared with a prespecified performance goal.
Kidney transplantation is the best renal-replacement in the setting of end-stage renal disease. However, some transplant candidates have developed anti-HLA alloantibodies (human leukocyte antigen). When they are numerous and when their strength assessed by mean fluorescence intensity (MFI) is high it is very complicated to find-out a suitable kidney allograft against which the recipient has a negative cross-match. In such a case the only hope for the patient is desensitization therapy, whereby the treatment will decrease anti-HLA alloantibodies below a threshold, i.e. MFI < 3,000, enabling kidney transplantation without risking antibody-mediated rejection. Desensitization relies on i) apheresis technics in order to withdraw circulating anti-HLA antibodies, and ii) immunosuppression, i.e. rituximab or tocilizumab, targeting B-lymphocytes, and tacrolimus/mycophenolic acid/steroids targeting T-cells. The type of apheresis is guided by the pre-desensitization MFI of anti-HLA alloantibodies, e.g. double filtration plasmapheresis or semispecific immunoadsorption. Likely the choice between rituximab and tocilizumab depends also on predesensitization anti-HLA antibody MFIs. At the end of the desensitization process, the patient will be able to get a kidney transplant either from a live-donor or from a deceased donor.
The objective of this pilot work is to determine the role of central and peripheral visions in explicit attention processes (saccade planning) in the case of visual impairment.
