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.
The aim of this study is to display the predictive factors of hearing rehabilitation after cochlear implant surgery in severely to profoundly deaf adults.
The primary objective of this study is to optimize the protocol for the TUS administration in patients with TRD while gaining an initial impression of treatment efficacy.
The purpose of this study is to evaluate the efficacy of glofitamab monotherapy compared with an investigator's choice of either rituximab plus bendamustine (BR), or lenalidomide with rituximab (R-Len) in patients with relapsed or refractory (R/R) mantle cell lymphoma (MCL).
Alcohol use is a causal factor in more than 200 diseases and injury conditions (see ICD-10) and in France, alcohol is the first cause of hospitalization. Binge drinking (BD) has emerged as a major public health issue among student populations and is associated with negative consequences and social, cognitive and brain alterations. More than half of French university students have reported BD in the past month and are at increased risk of several alcohol-related consequences such as memory and sleep impairments, and reduced quality of life. BD is also a major risk factor in the development of alcohol addiction, with individual and environmental factors playing a role that is still poorly understood. Moreover, most students and young adults are reluctant to seek interventions when it is provided by health care professionals (only 4-5%) and have poor insight with regard to their alcohol use patterns / habits. Thus, there is an urgent need for developing effective prevention and intervention programs to reduce alcohol drinking in students. Recent studies have demonstrated that new types of technology-delivered interventions are promising tools for addressing unhealthy alcohol use. For example, an uncontrolled trial pilot study using a smartphone application-delivered intervention produced a reduction in both number of drinks per week and BD from baseline to 3-month follow-up. A recent review also showed significant outcomes of a mobile health intervention for self-control of unhealthy alcohol use. The investigators hypothesize that a timeline follow-back and personalized feedback based on the use of a mobile application can reduce excessive alcohol intake at 3-months. This study will provide scientific knowledge about BD in students, but also regarding a new type of intervention that could be effective for prevention in non-treatment seeking individuals and reducing the severity of health problems associated with excessive alcohol intake.
The objective of this study is to explore the integration of in vivo and ex vivo of MRI with histology and molecular assessments to advance non-invasive characterization of tumor heterogeneity in high-grade serous ovarian cance
Covid is a virus that first appeared in China in 2019 and was quickly described as a pandemic virus by its globalized nature. The unprecedented occurrence of the virus has led to several health and restrictive government measures. The Covid-19 pandemic and health measures have been able to contribute to the deterioration of the mental health of citizens as it has already been observed during the former pandemic context (Sars covid in 2003 in China or the Spanish flu). Among the consequences of a negative impact on mental health, investigators assume that there is an increase in transitions to the completed suicidal act. However, current studies and observations tend to note that there has been no major change in the dynamics of successful suicides during the Covid period. However, there are biases in the studies conducted: some suicide deaths may have been hidden and not reported as such, due to several factors. For example, the measure of the evolution of suicide attempts that was most often made by the measure of the evolution of the number of hospitalizations for this reason can be a source ofestimate whether people who did this gesture were not hospitalized after a visit to the emergency room or if they gave up attending because of the pandemic. Moreover, suicide deaths are more difficult to report as such when they occur at home than after hospitalization. It is therefore interesting to study the dynamics of suicide during this health crisis retrospectively based on data from the Strasbourg Institute of Forensic Medicine containing the census of the Alsace region, which was hit hard by the pandemic.
Genetic diagnosis of Amyotrophic Lateral Sclerosis (ALS) could identify the origin of the disease, potentially allowing the patient to pursue targeted/gene therapy. However, many familial forms of ALS are genetically undiagnosed, either because no variant has been detected in the genes of interest, or because the detected variant(s) have uncertain significance. Currently, molecular diagnosis takes place in two stages: 1) Search for the GGGGCC expansion in the C9ORF72 gene by RP-PCR; 2) Analysis of the coding regions by high-throughput sequencing of a panel of 30 genes involved in ALS. Many of these variants of uncertain significance affect splicing. Their impact can be predicted using in silico tools, but only an analysis of the patient's RNA can confirm their pathogenic nature. Currently, the analysis of transcripts is only done a posteriori, when a variant predicted to impact splicing is detected on the patient's DNA. RT-PCR followed by Sanger sequencing then verifies the impact of the splice variants. This method confirmed the impact of certain splice variants in patients. However, this method is time-consuming and requires custom development, and is mutation/gene/patient-dependent. In contrast, high-throughput RNA sequencing (RNA-Seq) simultaneously analyzes the splicing of numerous genes, with a global approach, applicable to all patients. This approach avoids the custom design of primers, which can be biased by the interpretation of splicing predictions, while RNA-Seq systematically captures and sequences all the transcripts. Finally, RNA-Seq provides additional information compared to DNA sequencing such as the detection of exon skipping, intron inclusion, and the creation of fusion transcripts. In the GTEx project (GTEx Consortium, 2013), expression levels of human genome transcripts were quantified by RNA-Seq. Using these results, the study investigators measured expression of transcripts of known ALS genes in whole blood. Applying a threshold value of 0.5 transcripts per million reads (TPM), 25 of the 30 ALS genes currently analyzed by NGS in routine diagnostics at Nîmes University Hospital could be eligible for a complete analysis by RNA-Seq. None of the French laboratories carrying out genetic analyzes of ALS has yet developed RNA-Seq as a routine diagnostic tool. The study laboratory receives more than 600 requests for genetic diagnosis of ALS patients per year. The aim of this study is therefore to develop a global method for analyzing RNA transcripts of ALS genes to categorize the mutations to improve the diagnostic management of patients.
Various studies show an increase in the number of cases of early puberty in girls with breast development with a variable clinical presentation and evolution. This increasing phenomenon concerns girls between 6 and 8 years old. In a large number of cases, from 70 to 95% depending on the series, no medical cause is found and environmental factors are suspected to be involved. Descriptive studies of these patients are scarce and not always provide an overview of all the parameters in line with the concept of the exposome. The PENELOPE clinical trial will allow to analyze a large number of parameters, including the adipose tissue, its metabolism, the endocrine disruptors, and the epigenetic modifications, and to study the impact of environmental health measures in the evolution of these parameters. The data from the analyses of the endocrine disruptors of the patients will be explored in parallel in experimental models (amphibians, murine, cellular) in order to test potential mechanistic hypotheses.
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. It is characterized by different progressive forms with periods of flare-ups interspersed with phases of remission. MS manifests clinically with signs of multiple neurological dysfunctions as well as less specific symptoms such as fatigue, the prevalence of which is found to be high in these patients and is independently associated with an alteration in their quality of life. Recently, a non-invasive method for assessing maximal muscle oxidative capacity (mVO2) using optical measurement of muscle oxygenation (near-infrared spectroscopy, NIRS) has been described. Measuring tissue light absorption from a skin sensor facing a muscle, makes it possible to distinguish tissue concentrations of oxyhemoglobin (HbO2) and hemoglobin (Hb). The difference in absorbance of Hb and HbO2 corresponds to the balance of O2 supply and consumption in tissue capillaries, allowing calculation of a time constant (kNIRS, min-1) reflecting mitochondrial function. Current literature provides reference values in young healthy subjects and MS patients. This index could therefore constitute a particularly interesting non-invasive indicator of mitochondrial functioning, usable in the clinic.
[18 F]fluorodeoxyglucose (18F-FDG) positron emission tomography-magnetic resonance imaging (PET/MRI) is a new hybrid imaging tool that has recently arrived in oncology, and is particularly promising. Its usefulness seems obvious in certain tumor types, but its place in the staging of cervical cancers has never been explored in a prospective trial to our knowledge. Previously, a comparative retrospective study from 2009 found a better sensitivity of PET fused to diagnostic MRI images compared to PET/CT (positron emission tomography/computed tomography) in the detection of metastatic lymph nodes (54 and 44% respectively). It was an a posteriori fusion of images, from images acquired by PET-CT.
