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.
Few oral exams are performed on 6-year-olds (key age for carious disease). This project aims to increase the number of oral check-ups for 6-year-olds in fragile areas (REP/REP+ areas).
The ongoing SARS-CoV2 or Covid-19 pandemic is causing a major global health crisis. In France, it prompted an urgent reorganization of the healthcare supply, mobilizing caregivers and hospital staff in a climate of uncertainty. Health services have been put to the test, some staff being on the front line, others having faced the reorganization of the health system necessitated by such a pandemic. Frontline caregivers have been compared to "fighters on the front lines." They encountered many difficulties, such as direct exposure to patients with a high viral load, exposure to the risk of contamination, physical exhaustion, reorganization of workspaces, adaptation to rigid work organizations, the management of the shortage of materials, the unusually high number of deaths among patients, colleagues or relatives, ethical questions relating to decision-making in a strained healthcare system. The psychological impact on these hospital staff is an indirect issue of such a pandemic in terms of mental health. The investigators have little data in the literature on the incidence of psychiatric episodes in the post-epidemic period. Work on the impact of two major pandemics of influenza A H1N1 (2009) and SARS-CoV-1 (2003) on the mental health of caregivers and other staff working in hospitals reports increased rates of mental disorders after discharge from anxiety-type crisis, depression and post-traumatic stress. This over-representation of mental disorders was still found several years after the epidemic. Similar results are emerging in recent studies involving hospital staff who were used in the Covid-19 crisis. These highlight a certain number of risk factors for the occurrence of these disorders (young age, nursing profession, underlying psychiatric pathology, exercise carried out in the first line of Covid).
Alzheimer disease is hard, long and expensive to diagnose. In order to help the clinician, a new biomarker in Alzheimer disease seems to be very useful. The retina, as a window of the brain, could offer a new way to diagnose this common disease. Indeed, a retinal atrophy could especially appear in Alzheimer disease. Besides, many aspects about retinal alteration, visual function and their link with the disease deserve to be more explored. So as to fill these gaps, a new study about retinal specificity in Alzheimer disease appears to be relevant.
The year 2020 was marked by the emergence of a new respiratory disease: COVID19 related to an infection with the coronavirus SARS-CoV-2 (name given by the WHO on February 11, 2020). Initially appearing in China, in the province of Hubei, this epidemic has rapidly spread to be declared a global pandemic on March 12, 2020 by the WHO.Given the current context of the COVID-19 epidemic, strict hygiene measures have been taken in scanning rooms with systematic bio-cleaning. Strategies have been modified as a matter of urgency, with changes in the practices of electro radiology manipulators who work in "isolation" to avoid contamination. The number of scanners has increased exponentially following the curve of the epidemic, making it more and more difficult to systematically check the images before the patient leaves the room. To ensure sufficient image quality for interpretation of all scans, a complementary acquisition in ULD, with very low exposure, was systematically added to the acquisition protocol. The standard acquisition in LD, associated with this acquisition in ULD remain well below the diagnostic reference thresholds dictated by the nuclear safety authority (NRD: 350 mGy.cm. In Nîmes: LD: 100 to 150 mGy.cm and ULD: < 15 mGy.cm). These two acquisitions allow us to avoid breathing and movement artifacts, etc., without having to have the patients return for a new scan in case of a bad acquisition. This avoids an overexposure of the staff to the risk of infection by the SARS-CoV-2 virus. The main objective of this retrospective study is to evaluate the diagnostic performance of ULD vs. LD for the accurate diagnosis of COVID-19 pneumopathy which presents a particular ground glass pattern Our study will demonstrate that the ULD scanner can be used in the search for COVID-19 pneumopathy and thus limit the exposure of patients to X-rays, especially since thoracic scans are often repeated.
This work consists, first of all, in making an inventory of the physiotherapy of the patient undergoing cardiac surgery under high flow oxygenation at the CHRU NANCY. Then, in a second step, the impact of the physiotherapy on the lung ultrasound score associated or not with the NIV of the patient under OHD after cardiac surgery will be studied. The objective is therefore to answer the following research question: what is the impact of a physiotherapy session with or without non-invasive ventilation in patients receiving high flow oxygenation after cardiac surgery on the lung ultrasound score measured by ultrasound? Main hypothesis: Physiotherapy is associated with NIV when it is prescribed in patients undergoing high flow oxygenation after cardiac surgery. Secondary hypothesis: Physiotherapy + NIV further improves pulmonary aeration versus physiotherapy + high flow oxygenation.
Evaluation of the clinical safety and effectiveness of hydrophilic acrylic intraocular lens
3D FLAIR, 3D T1 FAT SAT, coronal T2 and coronal T1 dixon sequences were usually used to assess visual deficits in MRI. Optic nerve examination is preferably performed using a coronal T2 sequence in order to detect a hypersignal suggestive of inflammation whereas brain examination is preferably performed using a 3D T1 sequence to highlight signs of spatial dissemination and lesions suggestive of multiple slerosis (MS). No study has yet investigated the detection capabilities of 3D T1 for the detection of optic nerve inflammation. The objective of this retrospective study was to determine whether a single 3D T1 sequence allows simultaneous exploration of the optic nerve and the brain for the positive diagnosis of optic neuropathy and/or MS.
This observational exploratory prospective study will evaluate the performance on an Artificial Intelligence (AI) solution interpreting ECG (electrocardiogram) collected from an Apple Watch (AI-AW) in the detection of Atrial Fibrillation (AF)
Occurrence of acute right heart failure (ARHF) remains common during pulmonary hypertension (PH). Right atrial pressure (RAP) invasive measurement is the gold standard to diagnose ARHF in order to improve diuretic treatment management. Existence of indirect signs of ARHF on venous Doppler ultrasound waveform has long been described, but correlation with RAP has not been properly established yet. It is the aim of our study in order to obtain an additional tool to manage ARHF.
3D FLAIR, 3D T1 FAT SAT, coronal T2 and coronal T1 dixon sequences were usually used to assess visual deficits in MRI. Optic nerve examination is preferably performed using a coronal T2 sequence in order to detect a hypersignal suggestive of inflammation whereas brain examination is preferably performed using a 3D FLAIR sequence to highlight signs of spatial dissemination and lesions suggestive of multiple slerosis (MS). Recently, a study based on a small number of patients showed the interest of 3D FLAIR in the detection of the hypersignal of the optic nerve.The objective of this retrospective study is to determine whether a single 3D FLAIR sequence allows simultaneous exploration of the optic nerve and the brain for the positive diagnosis of optic neuropathy and/or MS.
