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.
Joiner's interpersonal theory of suicide postulates that the wish of death comes from feelings of perceived burdensomeness and thwarted belongingness. But, only people who have acquired the capability to kill themselves will attempt suicide. The acquired capability refers to a reduction of fear to death, and a higher pain tolerance. Indeed, to commit suicide involves to endure pain during the act. Thus, higher pain tolerance seems to be a necessary feature for suicidal act. Past studies have shown higher pain threshold and tolerance in suicidal patients, whatever the stimulus was (electric, thermic or mechanical), compared to patients without suicide history. Moreover, Caceda and colleagues demonstrated higher pain threshold in recent suicide attempters (suicidal act within 72h) compared with depressed patients. Five days after the initial evaluation, pain threshold of recent suicide attempters decreased to be similar to depressed patients with suicidal ideation. Therefore, it may exist a specific state during which the pain tolerance is increased. During this "hypoalgesic state" patients with suicidal ideation could attempt suicide to get relief from suffering. However, little is known about the specific mechanisms that are responsible for the higher pain threshold and tolerance in suicide attempters. Pain is a dynamic system that results from excitatory and inhibitory messages. The modification of one of these mechanisms could explain the higher tolerance in recent suicide attempters. Three of them are of particular interest: 1. The conditioned pain modulation (CPM) is a modulatory pain mechanism. CPM works through descending pathway that reaches the spinal cord and modulates pain processing from the first nociceptive synapse.In recent suicidal patients, an increase of the CPM could explain higher pain tolerance. 2. The "wind-up" mechanism is defined as the highest excitability of the second order nerve. Even if the stimulus remains stable, pain continuously raises. In recent suicide attempters, a reduction of this mechanism could explain higher pain tolerance. 3. The threshold of Aδ and C nociceptors. If a nociceptive fiber is less excitable than the other, it would explain higher pain threshold.
Postoperative ileus (POI) is a serious complication after colorectal surgery. One of its most frequent consequences is the replacement of nasogastric tube because of the vomiting. Vomiting is due to the distension of the stomach and information on the evolution of gastric filling after surgery could help to better understand the physiopathology of POI. It could also give indication to help the physician in the management of POI. The ultrasonography has been shown to be a reliable technic to assess the gastric emptying. To date, there is no indication in the literature about the evolution of the gastric filling after colorectal surgery while these information could help to identify patients at risk for POI and to predict the need for POI replacement.
From the medical records of a series of patients operated on for incident grade II and III glioma, the primary objective is to evaluate the correlation between the molecular profile of tumours and preoperative imaging data (by FDG and FDOPA PET-scan and multimodal MRI).
The main objective of this study is to evaluate the benefit of personalized prostheses compared to conventional prostheses on patient satisfaction 24 months after total knee arthroplasty.
Cerebral palsy (CP) describes a group of permanent disorders of the development of movement and posture, causing activity limitation, that are attributed to non progressive disturbances that occurred in the developing fetal or infant brain. The motor disorder of CP are often accompanied by disturbances of sensation, perception, cognition, communication, and behaviour; by epilepsy, and by secondary musculoskeletal problems. Motor activities, especially walking, can be affected by many factors including sensory deficits, biomechanical and postural limitations, muscle weakness and spasticity.To provide feedback, during gait rehabilitation is a complementary approach to improve motor learning during the rehabilitation protocol. However, the feedback modalities are multiple and no study has compared these modalities. This study aims to test which feedback modalities could control the gait parameters (speed, cadence, step length) of the child with CP in real-time, through an augmented reality environment.
Since March 2020, SARS-CoV2 virus (nCoV19; COVID-19) is considered pandemic. Its high rate of spread and infection in the human population and the lack of effective and validated treatment have led the authorities of several countries to confine their populations to slow the spread of COVID-19. As part of the management of this health crisis, the screening of individuals is essential in order to isolate "infected cases". These screening tests are currently performed on nasopharyngeal swabs using RT-PCR for the detection of viral RNA. Although sensitive and specific, these tests remain relatively long (2-5 hours), expensive and the strong international demand for nucleic extraction kits and enzymes are factors limiting the implementation of widespread screening (problem of supply of swabs, molecular biology consumables). In order to prevent the risks of a shortage of screening means, we propose to develop an innovative alternative strategy, PCR-free, based on the detection of specific protein signatures in human saliva by MALDI-TOF MS profiling. MALDI-TOF MS profiling is a method used in routine diagnostics by microbiology laboratories for the identification of microorganisms. MALDI-TOF MS profiling has been successfully used to classify individuals according to their infectious status (oral pathologies) based on the analysis of their saliva, but also as a tool for the identification of respiratory viruses from cell culture supernatants. In addition, we have expertise and skills in the field of MALDI-TOF MS profiling and have implemented new strategies to improve the quality of profiles and their analysis, particularly in the context of entomological and vector identification projects. Finally, recent Chinese studies have reported that COVID-19 was detectable in saliva by RT-PCR. The main objective of this study is to develop a test based on the MALDI-TOF profiling method to detect individuals infected with SARS-CoV2 from saliva sample.
Description of the neurological impairment: clinico-radiological and electrophysilogical correlations
The objective of this study is to look for the presence of SARS-CoV-2 in the semen of patients diagnosed with COVID+ based on RT-PCR analysis of nasopharyngeal swabs.
Open water swimming is a swimming discipline which takes place in outdoor water such as open oceans, lakes, and rivers. Elite swimmers are exposed to hypothermia when swimming in cold water, especially in long duration races, such as the 25-km race. The objective of this study is to evaluate the change in body core temperature in swimmers with continuous temperature monitoring during a 25-km race. The secondary objective is to identify the predictors of hypothermia and hypothermia-related drop-out.
This nasopharyngeal (NP) carriage surveillance study was requested by the European Agency for the Evaluation of Medicinal Products as a post-licensing commitment to determine whether the use of the pneumococcal conjugate vaccines (PCVs) including 7 then 13 valents (introduced in 2001 and 2010, respectively) caused a shift in the distribution of Streptococcus pneumoniae serotypes in children with acute otitis media and modified the resistance of this bacterial species to antibiotics.
