There are about 36465 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 is a proof-of-concept trial of vonafexor safety, its effects on kidney function in subjects with at risk of progression Alport syndrome.
This clinical study will test a newly developed cochlear implant known as CI622D. This experimental cochlear implant has been designed to slowly release a drug called dexamethasone. Dexamethasone works to ease inflammation, which is common after any surgical procedure. The goal is to learn if there are added benefits in implant performance and hearing outcomes with the dexamethasone-releasing cochlear implant (CI622D) vs. the standard cochlear implant (CI622) without dexamethasone. The study will be conducted in adults with sensorineural hearing loss, a type of hearing loss caused by damage to the inner ear or auditory nerve. The study participants will undergo a series of tests that include testing their implant and their hearing. They will also complete questionnaires to see how they rate their hearing ability and their overall general health.
Amputation causes somatic and psychological damage. Prognostic factors for postoperative gait recovery include the need for proprioceptive re-education for dynamic balance. Improved gait patterns and use of the prosthesis contribute to an overall improvement in the amputee's autonomy. Virtual reality coupled with movement analysis allows personalization of treatment with objective assessment of progress. The study authors hypothesize that a virtual reality protocol for the dynamic balance of a unilateral transtibial amputee in initial rehabilitation will improve the dynamic balance assessment criteria compared with a conventional rehabilitation protocol.
Echocardiography is recommended for the hemodynamic management of patients with shock. Recently, a new echocardiographic method has been proposed that provides a non-invasive measurement of myocardial work incorporating different components, namely total myocardial work (GWI), constructive myocardial work (GCW), lost myocardial work (GWW) and effective myocardial work (GWE). Echocardiographic measurement of myocardial work takes into account both myocardial deformation and left ventricular afterload (estimated by measuring systolic blood pressure) and, unlike the measurement of left ventricular ejection fraction and global longitudinal strain, could be less dependent on cardiac load conditions, particularly left ventricular afterload. To date, non-invasive measurement of myocardial work has never been validated in critically ill patients, and no study has assessed the effects of different therapies (fluids administration, administration of norepinephrine) on the different components of myocardial work in patients admitted to intensive care unit.
This study will estimate the real-world effectiveness of adjuvant nivolumab therapy in adult participants with muscle invasive urothelial carcinoma (MIUC) in France.
In order to assess the risk of hepatitis B reactivation in people living with HIV and undergoing injection therapy, we propose to carry out a descriptive analysis of the evolution of hepatitis B markers in this population.
Polycythemia (PG) corresponds to an increase in erythrocyte parameters on a blood test. A distinction is usually made between primary and secondary PG. The most common primary PG is Vaquez's disease, a hematological cancer. In Vaquez disease, an increase in hematocrit has been reported to be associated with a logarithmic increase in blood viscosity. The main complications of primary PGs (especially in Vaquez disease) are thromboembolic complications. In contrast, thromboembolic complications are rarer in secondary PG. In Vaquez disease, a hematocrit ≤ 45% has been defined as the therapeutic goal for significantly reducing thromboembolic risk. However, this has not been established for secondary PGs. All in all, the definition of the 45% threshold is based solely on clinical studies with no obvious biological argument. What's more, simply lowering blood mass through cytoreduction alone does not appear to be sufficient to significantly reduce thromboembolic risk. To investigator knowledge, there are no studies prospectively evaluating blood viscosity, its determinants and coagulation in different types of polycythemia. Nor are there any data on the direct effect on blood viscosity of the various treatments usually offered.
Clearing the airways is a complex phenomenon involving the production of secretions, the nature of mucus (viscosity, elasticity, stringiness, and adhesiveness), ciliary movement, and coughing. In intubated and ventilated patients, endotracheal suctioning occur when the patient is "unable to clear the airways of obstructions hindering the free passage of air." These suctioning can lead to transient desaturation exacerbated by a decrease in cardiac output due to increased mean arterial pressure, promoting cardiac arrhythmias. To minimize these effects, it is recommended to perform additional preoxygenation, by increasing the fraction of O2 in the air delivered to the patient by the ventilator 2-3 minutes before the procedure. These longstanding recommendations were reiterated in 2022, based on outdated studies involving systematic suctioning that required disconnecting the patient from the ventilator. Currently, suctioning are performed on-demand, based on the patient's congestion status, either through the endotracheal tube cap or a "closed system." Desaturations have become infrequent without establishing that additional preoxygenation can prevent them. Moreover, additional preoxygenation is not without risks. By inducing de-nitrogenation atelectasis with a loss of lung volume, it can exacerbate pre-existing lung injuries in the most severe patients. In less severe cases, preoxygenation leads to transient hyperoxia, with various deleterious effects impacting patient prognosis. Thus, a short-term risk, such as deep desaturations, must be balanced against a medium-term risk of hyperoxia and de-nitrogenation.
Palpitations are a frequent reason for consultation (16% of total volume) and management in the emergency department. Conventional diagnostic management in our establishment is based on a 48-hour external ECG holter, combined with a stress test if symptoms are triggered by physical activity. The diagnostic difficulty lies in the frequency and duration of this transient symptom. At the time of consultation, the patient is often asymptomatic. The initial strategy is to demonstrate an electrocardiographic trace during the attack, in order to adapt management to the chosen etiology. The HOLTER ECG is the gold standard, but it is not very cost-effective due to the infrequent and random nature of the onset of symptoms. The advent of accessible connected tools such as connected watches seems to be an interesting alternative for acquiring a per-critical trace of symptoms. They are widely adopted by the general population, with ease of use by the individual and long monitoring times. The main aim of the study is to establish the diagnostic cost-effectiveness of one or other of the two diagnostic strategies (rate of identification of the causal arrhythmia) at 6 months from the cardiological consultation.
The goal of this interventional study is to describe how people with cochlear implants perceive the perceive speech in noise and their sound environment on adults who are native French speakers with typical hearing or with cochlear implant(s). The measures and strategies developed in this project could benefit all current and future cochlear implant wearers by improving their perception of the sound environment and their quality of life on a daily basis. Researchers will compare normal hearing participant and participants with cochlear implant to describe the speech in noise and their perception of the sound environment. Participants will perform audiological tests to assess their perception of the sound environment, with and without speech enhancement.
