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.
Epidemiological data have related particulate matter (PM), nitrogen dioxide (NO2) and ozone (O3) to COVID-19 morbidity and mortality at the population level. Air pollution may be related to an increase in the COVID-19 severity and lethality through its impact on chronic diseases such as cardiovascular and respiratory diseases and diabetes that are also the main comorbidities associated with COVID-19. Epidemiological studies using individual data are needed to provide more precise estimate of the association between air pollution exposure and COVID-19. In this multicenter prospective study, the investigators will analyze the number of deaths in COVID-19 confirmed cases in geriatric patients according to long-term exposure to air pollution, taking into account confounders such as diabetes, hypertension, age, and BMI. Exposure to air pollution will be estimated as the mean concentration of air pollutants at the residential address during the previous two years. In addition, the investigators will explore the relationship between short-term variations in air pollutants, relative humidity, temperature, UV radiations, pollen and the occurrence of COVID-19.
Impacts of the Covid-19 epidemic and associated lockdown measures on the management, health and behaviors of cystic fibrosis patients during the 2020 epidemic
Reversible Cerebral Vasoconstriction Syndrome (RCVS) is a syndrome described at the end of the 20th century. Generally, it has a benign course. It is revealed by acute headaches, in different circumstances such as sexual activity, physical exertion or emotional disturbances. But, in few cases, it might be complicated by seizure, stroke and subarachnoid haemorrhage. The diagnosis is confirmed on radiological examination, which shows diffuse cerebral vasoconstriction of brain vessel. It calls reversible because at three month, vasoconstriction disappears. Most cases occur during post partum or after serotoninergic/adrenergic drug use. The pathophysiology is unknown but a transient disturbance in the control of cerebrovascular tone by sympathic hyperactivity and/or endothelial dysfunction are suspected. The assessment of endothelial dysfunction in brain is possible with transcranial doppler. Chen et al. showed an impairment of vasodilatation post apnea induced called BHI on RCVS subjects compared with healthy control. BHI is a reflect of endothelial function in brain. Currently, investigators do not know if endothelial dysfunction occurred only in brain or if it may occur in systemic vessel. Some case reports talk about systemic complication such as kidney infarct or hepatic arterial vasospasm so a systemic vascular dysfunction may be suspected. In this study, researchers will study systemic endothelial function by measure of the pulse wave velocity during RCVS and after its recovering at 3 months, and compare it at healthy controls.
Real-time ultrasound guidance for central venous catheter catheterism is recommended in order to reduce complication, in particular for internal jugular site1. Nevertheless, the usefulness of ultrasound guidance for subclavian approach remains controversial, in particular because needle visualisation is more complex as compared to jugular site2,3. New magnetic devices (Needle-pilotTM device, Samsung Healthcare) could theoretically allow a better needle visualisation and a better success rate. The investigators hypothesize that such device could improve the feasibility of subclavian catheterism. As this device has not been evaluated in patients, the investigators decided to perform a simulation study on a human torso mannequin. This methodology has been already used by Vogel et al in 20154. The main objective aims to compare the procedure time between conventional real time ultrasound guidance and guidance with Needle-pilot™ device.
Post operative ileus refers to an disrupt in normal gastrointestinal motility responsible of nausea and vomiting. It occurs in about 15-20% of colorectal surgeries. Some preventive measures have been included in the Enhanced Recovery After Surgery Program such as early mobilisation and enteral feeding or minimal invasive approach. Abdominal massage is not widely applied amongst general surgery team and is not part of the recommendation. This technique refers to profound manœuvrers of visceras through abdominal palpation and breathing, and has been used as part of the local protocol of Grenoble Alps University Hospital for many years with satisfactory results. No complications have been reported. Various studies have evaluated the value of physiotherapy and massage for resumption of normal bowel function. A study from Rouen University Hospital demonstrated that a mechanical stress to the cuteaneous tissue by LPG Cellu M50® machine would reduce pain and lower the time to first flatus. Similar results were obtained after Cardiac surgery. In a preclinical study on operated rats, abdominal massage also improved normal bowel function recovery. Physiotherapist plays a key role in RAC. Their action on respiratory function (movement of diaphragm) and musculoskeletal system (early walking) allows a faster recovery and a reduction of time of hospitalization. Even though the results on time to first flatus and anxiety seem interesting, Deep abdominal massage has never been evaluated.
The objective of the study is to measure the evolution of the quality of life in infants between 0 and 5 months old, not breastfed and suffering from regurgitation or colic.
Endometriosis affects 6-10% of women in childbearing age. It is a heterogeneous disease with three different forms: superficial endometriosis (peritoneal), ovarian endometrioma and deep pelvic endometriosis (subperitoneal). Surgical management of endometriomas is justified in cases of significant clinical symptoms (like pain), especially in cases of resistance to medical treatment. Currently, laparoscopic cystectomy surgery is the recommended technique to treat ovarian endometrioma. However, it is now well demonstrated that this surgery significantly reduces the ovarian reserve. Ethanol sclerotherapy is an alternative technique used to treat ovarian endometriomas. Several studies demonstrated the effectiveness and safety of this treatment, particularly in terms of preserving fertility. Regarding these reassuring data, many clinicians changed their practices and propose this technique as a first-line surgery. Ovarian reserve comprises two elements: size of the primordial follicle stock and quality of the ovocytes. Antimüllerian hormone (AMH) has been shown to be the best marker of fertility. The aim of this study is to observe changes in AMH levels after endometrioma sclerotherapy. This study is conducted in the Hospices Civils de Lyon, in 3 different sites.
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.
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.
