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.
Anterior cruciate ligament (ACL) tears are associated with concomitant lesions of the anterolateral ligament (ALL), which increase rotatory instability of the knee. If untreated, ALL insufficiency can compromise the results of ACL reconstruction, with higher risk of iterative ACL tear or additional meniscal lesion. Several surgical techniques have been described to reconstruct the ALL. Indications are increasingly frequent and actually, consensus being young patients, patients practising pivot sports, significant rotational laxity on clinical examination with a positive pivot shift test, or in cases of iterative surgery. To date, the two most popular techniques are the Lemaire technique (use of a fascia lata strip) and LAL reconstruction plasty (use of part of an accessory hamstring tendon). The older Lemaire procedure, popularized in the 1980s has proved its efficiency in terms of biomechanics, safety and reproducibility. More recently, following a new, precise anatomical description, anterolateral ligament plasty (ALL) has been developed, which is intended to be more anatomical than Lemaire's technique, but whose clinical superiority has not yet been demonstrated. Both techniques are currently used in our department, with the choice of technique left to the surgeon's discretion. To date, no randomized prospective study has demonstrated the clinical superiority of one technique over the other with a long term follow up. The aim of this study was to compare graft survival of ALL reconstruction versus modified Lemaire LET in combination with ACL reconstruction with a minimum follow up of 2 years. Secondary aim was to compare functional outcomes between both groups.
Cell-free fetal DNA (cffDNA) is present in the maternal blood from the early first trimester of gestation and makes up 5%-20% of the total circulating cell-free DNA (cfDNA) in maternal plasma. Its presence in maternal plasma has allowed development of noninvasive prenatal diagnosis for single-gene disorders (SGD-NIPD). This can be performed from 9 weeks of amenorrhea and offers an early, safe and accurate definitive diagnosis without the miscarriage risk associated with invasive procedures. One of the major difficulties is distinguishing fetal genotype in the high background of maternal cfDNA, which leads to several technical and analytical challenges. Besides, unlike noninvasive prenatal testing for aneuploidy, NIPD for monogenic diseases represent a smaller market opportunity, and many cases must be provided on a bespoke, patient- or disease-specific basis. As a result, implementation of SGD-NIPD remained sparse, with most testing being delivered in a research setting. The present project aims to take advantage of the unique French collaborative network to make SGD-NIPD possible for theoretically any monogenic disorder and any family.
Our project is a large-scale characterisation of cHCC-CCA will allow us to determine which subsets harbor actionable gene alterations. We will also aim to improve diagnosis of this tumor type by the use of immunohistochemical biomarkers and the development of deep-learning based models able to help cHCC-CCA diagnosis. This will represent an important step towards precision medicine for the patients with this highly aggressive malignancy.
To investigate the efficacy of MT-7117 on time to onset and severity of first prodromal symptoms (burning, tingling, itching, or stinging) associated with sunlight exposure in adults and adolescents with EPP or XLP.
Specifically, in this project, the objective will be developped a model to capture imaging-based tumor heterogeneity with multiscale radiomics approach by obtaining the mirror tumor image at in vivo MRI, ex vivo MRI at histology. This imaging model giving a perfect virtual histology tumor representation will be secondary implemented on routine in vivo clinical MRI for early cancer detection and treatment monitoring. Successful completion of this proposal will lead to a comprehensive non invasive characterisation of pancreatic cancer and will be a game changer in patient management.
VRMARS is a medical simulation study in microgravity. Healthy volunteers (n=18) test in microgravity the functionnality of an augmented reality headset in which a medical assistance is displayed.
Concussions in sports are a major public health problem because of their frequency, and are often underdiagnosed because of an unspecific clinical picture or sometimes masked by the concussion itself. Support data has been constantly evolving in recent years, including the last publication of the Berlin Consensus in 2016 specifying support in the field. However, to date, there is no tool to predict the severity of a concussion or to predict when it will return to play objectively and reliably. Brain MRI done after the head injury is most often normal. However, previous studies agree that there is a persistent electrophysiologic disturbance several weeks after the injury, and the specific pathophysiology of white matter changes after a head injury remains controversial. Diffusion tensor imaging (DTI), in addition to morphological sequences, is capable of assessing white matter microstructure and fibrous tract integrity or not. Several parameters, such as the seemingly normal white matter fractional anisotropy (FA) coefficient, the mean diffusivity and the radial diffusivity, may be altered in the aftermath of a concussion, indicating axonal damage not visible on conventional MRI sequences. Previous studies have evaluated these parameters with sometimes contradictory results: some have found an increase in AF in specific regions such as the cortico-spinal tract and the corpus callosum, others have found a decrease in AF. So far, assessment of a player's condition on and off the field after a head injury has been based on clinical criteria alone, sometimes far too subjective. The player may choose to mask their symptoms to allow them to return to the game faster, or feign more than they have. Once pathologies such as bone fractures or intracranial hematomas are ruled out by conventional imaging, there is no longer any tool for a more accurate diagnosis of possible microstructural alterations of brain tissue and for monitoring of the patient. The advent of new MRI techniques such as diffusion imaging, and particularly diffusion tensor imaging (DTI), is a promising tool to better understand white matter involvement in diffuse axonal lesions.
In France, falls among the elderly lead to more than 100,000 hospitalisations and more than 10,000 deaths each year. A French study published in October 2020 highlighted 5 profiles of older people who fall. However, this study is only based on falls of people over 65 years of age that required hospitalisation. In haemodialysis patients, several studies have shown that the incidence of falls ranges from 1.18 to 1.6 falls/patient/year. This population is more likely to be frail, suffer from sarcopenia, have reduced functional capacity and be polymedicated, all of which are associated with an increased risk of falls. Few studies have focused on falls in young patients. In one American study, where the population was predominantly African American (about 62%), 28.4% of patients had at least one fall during follow-up. The number of falls in people aged 45-64 years was similar to that in people aged over 75 years. In clinical practice, few patients report the occurrence of falls other than those leading to an emergency department visit or hospitalisation, and these falls are even less likely to be recorded in the medical record. To our knowledge, there are few or no data on falls in haemodialysis patients of all ages in a French population. This lack of knowledge is partly due to an underestimation of the problem associated with under-reporting. A study of the prevalence of falls in a haemodialysis population of all ages is therefore necessary to determine whether there is an interest in implementing a collective and/or individual prevention programme, possibly depending on the identified risk factors for falls.
Superficial dyspareunia are persistent or recurrent pains during an attempt at sexual intercourse or during effective penetration. They affect between 3 to 18% of women and are a source of physical and psychological suffering. Some health professionals (gynecologists, general practitioners, midwives) are confronted daily with these complaints. The approach of sexuality remains a complex subject even within the medical field. As a result, communication between women and health professionals can be difficult, leading to delayed diagnosis or inadequate management.
The purpose of the study is to compare the effectiveness of stimulation of the left precuneus by intermittent Theta Burst Stimulation to placebo stimulation on the severity of schizophrenia symptoms.
