title: Modeling Spinal Mobility in Ankylosing Spondylitis (AS) : Towards New Telekinetic Biomarkers

acronym: TELESPA

summary:
Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease that mainly affects the spine and pelvis in its axial form. It is responsible for chronic inflammatory pain and sometimes ankylosis with significant functional retention.

Clinicians need markers capable of precisely measuring the restriction of range of motion in these patients, reflections of the activity and/or sequelae of the disease.

The Inverstigators validated movement markers in the AS by a device including inertial sensors (XSENS) and computer modeling. The accuracy and repeatability of the XSENS-Awinda system compared to the reference measurement system have been demonstrated. The XSENS-Awinda device offers new real-time evaluation possibilities for quantitative gait analysis. This opens the way to new diagnostic tools, prognostics and therapeutic perspectives for the clinician.

title: L5-S1 Disc Fate in Thoracolumbar Arthrodesis Stopping at L5

summary:
Spinal deformity in adults is one of the most frequently treated pathologies in spinal surgery. Their surgical treatment remains a challenge. In particular, the choice of the borderline vertebrae for thoracolumbar fusion correction remains controversial, including the choice between an instrumented last vertebra at L5 and an arthrodesis extending to the pelvis. Studies and meta-analyses show that an ilio-sacral socket provides better correction of pelvic parameters and avoids the development of distal junctional syndrome. On the other hand, there is more proximal junctional syndrome in patients fixed to the sacrum, and the sacral socket exposes patients to the risk of pseudarthrosis of the L5-S1 level and failure of the fixation hardware. Moreover, although this factor is not described in the studies, it would seem that an ilio-sacral socket is more stiffening. Overall, no study has shown a statistically significant difference in clinical scores between patients whose last instrumented vertebra is L5 and those with pelvic fixation.

One of the theoretical risks of an extended fixation with a proximal thoracic grasp is to observe a premature disc degeneration of the L5-S1 disc since it would be subjected to more stress. This degeneration could be the cause of distal junctional syndrome and lumbo-radiculalgia due to inflammatory disc disease and disco-radicular impingement. However, to Investigator's knowledge, no clinical study has yet investigated the medium- and long-term fate of the L5-S1 disc in patients with extended fusion correction of a thoracic vertebra to L5.

Investigator's team has sometimes favored a final instrumented vertebra at L5 when possible, i.e., when the L5-S1 disc was considered to be minimally or not degenerative and when its horizontality could be obtained after correction of the underlying curvature. Investigators therefore have a cohort of patients who have undergone this technique. The usual follow-up of these patients includes a consultation appointment every 2 to 5 years and a control MRI at a distance of more than 5 years: investigators thus have a control MRI and the clinical score of the patients.

Investigator's objective is to determine whether there is degeneration of the L5-S1 disc, using MRI imaging data, which has never been published to investigator's knowledge.

title: Relationship Between Self-compassion and Treatment Adherence in Schizophrenic Spectrum Disorders

acronym: CompaSchizo

summary:
Treatment adherence is defined by the World Health Organisation (WHO) as the extent to which the patient's history of therapeutic drug-taking coincides with the prescribed treatment. In patients suffering from psychiatrical diseases, especially in those who are suffering from schizophrenic spectrum disorders, the quality of treatment adherence has to be improved. Indeed, non adherance to anti-psychotic treatment increases the risk of hospitalization, of substance use, violent behaviour and of functionnal and cognitif impairment. Selfcompassion, which involves being touched by and open to one's own suffering and to heal oneself with kindness and without judgement and self-criticism has never beed studied as a possible factor infuencing treatment adherence.

This study aims to evaluate if a link between selfcompassion and treatment adherence exists in patients suffering from schizophrenic spectrum disorders.

title: Metabolomic Approach During Exercise Testing in Myalgia Induced by eXercise

acronym: Matmix

summary:
Metabolic myopathies form a group of pathologies related to a deficit of muscle energy production (enzymatic deficit) by disorder of the metabolism of carbohydrates, lipids, purines, or mitochondrial involvement related to dysfunction of complex respiratory chain. Most often, the symptomatology may include signs of "muscular" calling with cramps, contractures or exercise myalgia, more or less associated with exercise intolerance with early fatigability and rhabdomyolysis. In practice, the clinical signs are not specific and not pathognomonic, or sometimes absent with only an isolated elevation of the CPK. The diagnosis of certainty is usually based on the realization of a muscle biopsy (invasive). Unfortunately, the performance of the biopsy (definitive diagnosis of myopathy) in front of myalgia is low, hence the interest of functional explorations upstream to better specify its indication.

Given the considerable increase in muscle metabolism to physical effort, resting investigations may not uncover myo-metabolic deficit. The muscle enzymatic deficit, is therefore most often "silent" at rest and its highlighting requires to explore the patient with effort, asking him to perform an exercise test on cycloergometer and/or an isometric contraction of the forearm ('handgrip test'). Currently, only a few metabolites are dosed before and after exertion such as lactate, pyruvic acid and ammonium. Several studies in normal subjects showed the effect of physical exercise on the metabolomic signature of plasma. Our aim is to apply modern metabolomic techniques to plasma and urinary samples collected as part of the care pathway in patients referred to in the Department of Sports Medicine-Functional Explorations of the CHU in comparison with healthy volunteers).

title: Brain Hemorrhage on 24h-CT and Functional Outcome in Stroke Patients With Cerebral Amyloid Angiopathy Features on Pre-thrombolysis MRI Treated With Intravenous Thrombolysis

acronym: Thromb in CAA

summary:
Background: In stroke patients treated with intravenous thrombolysis (IVT), presence and high number of strictly lobar cerebral microbleeds (compatible with cerebral amyloid angiopathy, CAA) seems to be associated with increased risk of hemorrhagic transformation, symptomatic hemorrhagic transformation, remote hemorrhage, and poor functional outcome. Some of these reported CAA patients with cerebral microbleeds also had chronic lobar intracerebral haemorrhage. Few data is available on IVT-treated CAA patients showing cortical superficial siderosis. There are no reports studying factors associated with brain hemorrhagic complication or functional outcome inside a group of IVT-treated CAA patients. Our aim was to evaluate brain hemorrhagic complications on 24h-CT and functional outcome after IVT in stroke patients with CAA features on pre-IVT MRI.

Methods: In our stroke center, IVT decision in patients with CAA MRI features is left at the discretion of the treating physician. We retrospectively screened pre-IVT imaging of 959 consecutive IVT-treated stroke patients (between January 2015 and July 2022) without ongoing anticoagulation therapy for probable CAA MRI features defined by modified Boston criteria. After exclusion of 119 patients with lacking MRI (n=47), with MRI showing motion artefacts (n=49) or with alternative chronic brain hemorrhage cause on MRI (n=23), 15 IVT-treated patients with probable CAA on pre-IVT MRI were identified. In these 15 patients, clinical, biological and MRI characteristics were compared between patients with vs. without post-IVT hemorrhage and between patients with poor (MRS 3-6) vs. good (MRS 0-2) functional outcome at discharge.

title: Effect of Acute Sleep Restriction on Responses to Hypoxia

acronym: HypSom

summary:
At altitude, humans are exposed to environmental hypoxia induced by the decrease in barometric pressure. On duty or in training, mountain troops, paratroopers or aircrew are regularly exposed to altitude. The effects of altitude on humans occur gradually from 1500 m and depend on both the duration of exposure and the altitude level. Cognitive disorders can occur from 3500 m (threshold of disorders) but there is a very large inter-individual variability.

The countermeasure to altitude hypoxia is oxygen but its use is not systematic between 3000 and 4000 m. Its use depends on the duration of exposure, without clearly established standards. Incapacitating effects on the operational capacity and health of soldiers can therefore occur as early as 3500 m.

In operations or during training, altitude exposure is often associated with a significant sleep debt (particularly during night or early morning missions), jet lag or precarious rest conditions in overseas operations. These sleep restrictions promote the degradation of mental performance with effects similar to those observed in hypoxia.

The combination of these constraints induces a physiological stress which can favour alterations in mental performance, an increase in incapacity, intolerance to altitude or the occurrence of altitude-related pathologies in military personnel. This could occur in particular in the operational zone around the threshold of disorders (3500 m) where the indication of oxygen is discussed.

The objective of this study is to assess the impact of acute sleep restriction on hypoxia tolerance.

title: Renal Denervation in Hypertensive Women Planning to Become Pregnant

acronym: WHY-RDN

summary:
Renal denervation is a new method to lower blood pressure (BP) in hypertensive patients by reducing the impact of sympathetic nervous system. Its efficacy has been demonstrated in resistant hypertension and in lowering BP in essential hypertension as compared to a sham procedure in untreated hypertensive patients. This procedure is safe without any serious adverse events. However its effects during pregnancy are unknown.

Normal pregnancy is associated with an increase of sympathetic activity at rest and upon cardiovascular reflexes stimulation which returns to baseline after delivery. These changes maintain optimal utero placental blood flow. But excessive stimulation of sympathetic activity may play a role in preeclampsia. Drugs that may affect the sympathetic nervous system are considered as safe in pregnant women.

So there are reasonable evidence that renal denervation performed before pregnancy should not have deleterious effects for the fetus. The efficiency of renal denervation being greater in young patient and in women, a greater proportion of BP normalization can be expected in this population of young women .

title: Belatacept as a Replacement for CNIs 3 to 12 Months Post-transplantation in Patients With Early Graft Dysfunction

acronym: BELASBRIDGE

summary: Calcineurin inhibitors (CNI) remain the standard treatment in renal transplantation to prevent rejection. Currently the main limitation of kidney transplantation is the occurrence of chronic graft dysfunction due to the CNI nephrotoxicity. Thus, strategies to minimize or stop CNI have been developed as belatacept, a fusion protein (CTLA4-Ig) blocking the ligand of the main CD28 costimulatory molecule. In the original phase III trial, used de novo in combination with MMF (without CNI) belatacept allowed to obtain a better renal function as soon as 1 year and a better graft and patient survival after 7 years. Despite these excellent results, belatacept has not become the gold standard due to a higher incidence of early rejection. In addition, belatacept is not covered by the french social security policy, because benefits are considered insufficient with respect to the cost. Patients with poor early graft function are a preferred indication of belatacept. It is then used instead of CNI at 3 months post-transplant allowing to improve kidney function without over-risk of rejection. Currently after conversion, belatacept is maintained indefinitely due to the supposed CNI chronic nephrotoxicity. However this one is more and more questionable. Thus, the investigators assume that in patients with poor function at 3 months posttransplantation the belatacept's benefit could be obtained by a transient replacement of CNI by belatacept from 3 to 12 months post-transplantation. It is the feasibility of this strategy and its medico-economic impact that the investigators wish to study.

title: Third Year Post-surgical Evaluation of Onset of Adjacent Segment Disc Degeneration in the Lumbar Spine According to the Initial Technique (Spinal Fusion Versus Lumbar Arthroplasty With Disc Replacement). A Monocentric Prospective Non-randomized Cohort Study.

acronym: ARTHRO-DEGE

summary: The main objective of the study is to compare the onset of adjacent segment disk degeneration in two groups of patients (one "spinal fusion group" and one "lumbar arthroplasty with disc replacement" group) with each patient acting as their own control for either group under study and more than three years of follow-up.


title: Evaluation of the Satisfaction and Relevance of Leadership Training for Residents - START Study

acronym: START

summary:
Health students are the future actors of the health system. They are exposed to many stressors in their journey. The quality of life of medical students is alarming worldwide: 11.1% of undergraduate and postgraduate residents reportedly have suicidal ideation and 27.2% have depressive symptoms. In addition, 44.2% suffer from burn-out syndrome. In the third cycle, 28.8% suffer from depressive symptoms and 35.1% from burn-out syndrome. This finding is shared internationally among medical residents. Health professionals are facing a global problem which it is crucial to act.

At national level, a survey on the mental health of young doctors carried out in 2017 found, among the 7603 residents who responded a prevalence: 22.8% of depressive symptoms, 59.7% of anxiety symptoms, 23.4% of suicidal thoughts, including 5.0% in the month prior to the survey. In 2018, a French report on the quality of life of health by Dr Donata Marra highlighted a real malaise affecting residents and the need to intervene "for residents, for carers and for patients", through the implementation of specific recommendations. The proposal 6 of the report emphasises the prevention of psychosocial risks through educational interventions such as training in collaborative management. On a personal level, the aim is to the leadership of each individual, in terms of stress management, communication, cross-disciplinary skills or even the introduction of relational simulations in the teaching of an awareness of deviant behaviour and harassment. The stress factors are indeed multiple during health studies confrontation with death, competition, increasing responsibilities… Perceived stress has a negative impact on the quality of life and burnout. Effective stress management strategies could therefore help to improve the quality of life of residents.

In this context, the analysis of the literature highlights three main areas of intervention that could contribute to resident leadership in favour of their quality of life: stress management, healthy living and the construction of a professional identity.

The Junior Leadership programme for residents from the beginning of their professional formation designed to provide basic knowledge and skills in healthcare leadership and to develop cross-disciplinary skills. The aim is to provide the necessary support for the success of the resident's professional project by participating in the improvement of their quality of life and the prevention of psycho-social risks.

The study therefore propose to evaluate the feasibility of training in leadership and meditation on the satisfaction of resident.

title: Study of the Determinants of Dream Recall and Content in Patients With Epilepsy

acronym: EPIDREAM 1

summary:
Dreaming is a sleep-associated cognitive process whose neural substrates and functions remain poorly understood. In healthy subjects, the frequency of dream recall is influenced by several factors such as age, gender, interest in dreams and sleep quality. The content of dreams mainly depends on waking life experiences, especially when they are recent and have a strong emotional content. The function of dreams remains debated but it is widely accepted that dreams play a role in emotional regulation.

Modifications in dreams are observed in several neurological diseases and sleep disorders, due to the modifications of sleep related to these diseases, as well as to associated disturbances in cognitive functioning and to the impact on such diseases on waking life. Epilepsy is a neurological condition characterized by a predisposition to seizures resulting from excessive and synchronized abnormal brain activity; it is associated with numerous co-morbidities including sleep and cognitive disorders, which are present in nearly one in two patients. However, the influence of epilepsy on sleep-related cognitive processes is poorly understood. It is suspected that nocturnal epileptic activity disturbs sleep-related memory consolidation processes, but the consequences of epilepsy on dreams have been little investigated.

The study of the determinants (epilepsy syndrome, location of the epileptic focus, presence of sleep-related seizures, certain anti-epileptic treatments, alteration of the quality of sleep) of dream characteristics in this context could lead to a better understanding of the dreams physiology, the interactions between epilepsy and sleep, as well as the cognitive and emotional functioning related to sleep in epilepsy. It could also determine whether dream characteristics can provide information on the epilepsy syndrome and on the presence of nocturnal seizures, and thus constitute a diagnostic tool.

In this cross-sectional observational study, we aim to identify determinants of dream recall in relation to epilepsy by administering a simple and brief questionnaire on sleep and dreams, to all consecutive patients seen in epileptology consultation during 12 months. Our objectives are

To determine whether the presence of sleep-related seizures influences the frequency of dream recall in patients with epilepsy
To describe the characteristics of dreams in epilepsy, the influence of epilepsy on dreams and to characterize the determinants of dream recall frequency in patients with epilepsy We hypothesize that the presence of seizures during sleep will be associated with poorer sleep quality, increased frequency of dream recall, and that we will observe the inclusion of epilepsy symptoms in dream content, particularly in subjects who are aware of their nocturnal seizures and are awakened by them.

title: Social-cognitive Functioning: Validation of a New Neuropsychological Test and Prediction of Social Behavioural Disorders in Daily Life

acronym: REALSOCOG

summary: It is now established that disturbances in social cognition are frequent in neurology and that they contribute to the development of social conduct disorders. Their assessment is therefore essential, particularly in order to propose early and adapted care. However, this assessment remains limited today. A new serious game-type test, REALSoCog, has been developed to address the shortcomings of current tools and to highlight disturbances in social behaviors. The latter are not always observed in consultation although they are often reported by caregivers. The objective of this research is therefore to validate the REALSoCog task in a pathological population (currently being standardized in the general population: CER-U, IRB N°: 00012020-115). The clinical interest of this task will be tested with a group of patients suffering from a neurodegenerative disease (Alzheimer's disease (AD), dementia with Lewy bodies (DCL), fronto-temporal lobar degeneration (FTD)) in order to assess its sensitivity and specificity in the detection of social-cognitive disturbances, and in particular in terms of social behaviors (detection of social behavioral disorders reported in daily life). The objective is also to document the socio-cognitive profiles in the mentioned diseases thanks to a more ecological test, and to better understand the links between socio-cognitive processes on the one hand, and individual characteristics on the other hand (e.g. mood and social participation).


title: Study of the Interest of Serum Calprotectin Determination in the Diagnosis of Spondyloarthritis and to Diferenciate With Fibromyalgia

acronym: Calprotectine

summary: To date, there are no biomarkers in spondyloarthritis that can differentiate between spondyloarthritis and fibromyalgia or other pathologies. Fecal calprotectin is a biomarker that is increasingly used in inflammatory diseases of the digestive tract. A growing interest in this biomarker is emerging in rheumatology, several publications have focused on its interest in rheumatoid arthritis, highlighting an association between serum calprotectin levels and disease activity. In spondyloarthritis, a few studies seem to show that it could be a marker of disease activity. Although a 2012 study found no difference in serum calprotectin levels between subjects with spondyloarthritis and controls. Still others have shown that it could be a predictive factor of radiological evolution in the same disease key. These data support, despite the questionable results of the Klingberg study, the value of this dosage in spondyloarthritis. The objective of this work is to show that this assay could be useful to differentiate spondyloarthritis from other pathologies with similar clinical presentation such as fibromyalgia.

title: Correlation Between LR-ACT and Anti Xa Activity During Endovascular Surgery Procedures.

acronym: AXAES

summary:
Activated clotting time (ACT) is currently recommended to monitor high concentrations heparin anticoagulation. ACT-LR was specifically designed to measure the activity of low dose of heparin used during endovascular surgery. The correlation between ACT-LR and Anti Xa activity which is considered as the gold standard seems to be debated.

Few studies in literature had shown controversial results. These studies were conducted in patients who underwent open as endovascular surgery. However, the ACT monitoring is not recommended in open surgery. In addition, heparin administration protocols are not described and specific to each centre.

In this study investigators want to study the correlation between LR-ACT and anti Xa after introducing a heparin protocol during complex endovascular procedures.

title: Reciprocal Benefit by Intergenerational Meetings Between 2 Fragile Populations

acronym: Part'Ages

summary: The investigators want to set up an experiment that allows a reciprocal benefit to 2 fragile populations: isolated seniors and disadvantaged children. The main hypothesis is that regular exchanges between these two populations reduce the feeling of social isolation of seniors and improve the school behavior of childrens. Therefore the investigators propose the following study design. The seniors and childrens will meet once a week, for 7 months, in a defined location in the city of Vallauris, over a period of one and a half hours, outside school hours (4:30 p.m. to 6:00 p.m.) and school holidays. During the school holidays the group will meet 3 times for day-long activities in the presence of at least one of the parents and possibly brothers and sisters. At the end of the project, a convivial evening will be organized in the presence of the families. The group will meet in a room in the city center and in the presence of a facilitator so that an adult will never be alone with a child. The formed pair will follow a defined schedule where will alternate activities proposed by the senior, sessions proposed by the facilitator and convivial moments in the presence of families . During the sessions proposed by the senior, he will offered the child a leisure activity that he likes and masters (eg gardening, DIY, sewing, etc.). All the proposed activities will be validated upstream by the project managers. The sessions proposed by the facilitator (e.g. games, walks) could be done with the participation of an outside speaker (e.g. for writing a gazette). A new evaluation session will be offered to all participants at the end of the meeting period, then at the end of the project, 1 month after the end of the meeting period.

title: Efficacy of Maintenance Repetitive Transcranial Magnetic Stimulation (rTMS) Treatment in Reducing Auditory Verbal Hallucinations (AVH) With High Frequency and Neuronavigation Guidance: A Double-blind, Randomized and Multicentric Study

acronym: MAINSTIM

summary: Repetitive transcranial magnetic stimulation (rTMS) can alleviate persistent auditory verbal hallucinations (AVH) in schizophrenic patients, but the classical procedure with low-frequency stimulation for several weeks upon the left temporoparietal junction have shown modest therapeutic effects, and there is currently no robust predictive factor to the response of the treatment. In a previous multicentric, randomized, and double-blind controlled study, it has been demonstrated that a high-frequency rTMS over an anatomical target can rapidly affect AVHs. Moreover, an intensification of the classical procedure delivering 20-Hz rTMS over a 2-day period was used in addition to a personalized anatomical stimulation target and neuronavigation guidance. Besides the significant efficacy of the procedure, the efficacy was maximal at two weeks after the end of the treatment. In this project, the hypothesis is that the two-day cure could benefit from maintenance rTMS sessions every week for one month and then every two weeks for 3 months to provide an optimal strategy for a long-lasting AVH reduction. This has for now never been tested. Predictive factors to the response of the treatment are also investigated.


title: Establishment of an ex Vivo Tumor Collection of Triple-negative Breast Cancers in Order to Validate the Interest of Innovative Therapies and the Search for Predictive Biomarkers of Response to Treatment

acronym: TRIPLEX

summary:
Initially described in 2009 on LGR5 positive stem cells from intestine, organoids correspond to a 3D cell culture that preserves the organization and part of the initial function of the organ from which the cells were derived. They use the proliferation and differentiation properties of stem cells cultured in a three-dimensional matrix.

These principles have been adapted to many human organs, including the breast. These culture conditions have thus allowed the establishment of cancer organoid lines that have the advantages of rapid amplification, a high rate of establishment success and unlimited proliferation potential. They are transfectable and cryopreservable. They are very close morphologically and genetically to the tumor from which they derive. Very recently, the in vivo response of orthotopic xenograft models of breast cancer organoids has been correlated to the in vitro response of these same organoids. In addition, the in vitro response of various of these models to PARP inhibitors was linked to the presence of the BRCA1/2 mutant signature, highlighting the potential of these models to predict patient response to these treatments.

Furthermore, one study demonstrated the value of using organoids derived from metastatic gastrointestinal tumors to predict patient response to cancer treatments (100% sensitivity, 93% specificity, 88% positive predictive value, and 100% negative predictive value.

title: Interest of a Weekly Consultation by a Medical Electro Radiology Manipulator (MERM) in Addition to the Follow-up by the Radiotherapist to Improve the Collection of Radio-induced Toxicities in Patients Undergoing Proton Therapy: Randomized Controlled Trial

acronym: MERMOSE

summary:
To our knowledge, the investigators have not found any scientific article dealing with cooperation between radiation oncologists and medical radiation technologists in the context of monitoring patients undergoing radiotherapy. Cooperation protocols between health professionals are in progress but concern mainly technical procedures (ultrasound, laserthermal sessions).

This study aims to evaluate whether MERMs, after training by physicians, can monitor clinical signs (for usual well-described toxicities) during treatment via a dedicated consultation.

This approach participates in the development of new professions and cooperation protocols between health professionals. This mission of accompaniment on a dedicated time would make it possible to develop the caring role of the medical electroradiology manipulator.

title: ACTA2 and Familial Aortopathies: Creation and Validation of an Exploratory Cellular Model

acronym: FACE

summary: The prevalence of hereditary aortic disease (HTAD), responsible for aneurysm or dissection, is estimated at 25%. Mutations in the ACTA2 gene represent the main cause of non-syndromic forms (10-21%). ACTA2 is expressed in vascular wall smooth muscle cells (VSMC) and encodes alpha actin (α-SMA). This actin isoform is in the majority in VSMCs and plays a key role in their contractile properties. The mutations are dominant-negative and lead, in a fibroblast model, to defects in the organisation of the actin cytoskeleton and to an increase in the migratory and proliferative potential of the cells. In vivo, VSCMs exist in a phenotypic continuum ranging from a quiescent differentiated contractile state to a so-called synthetic state in which cells are proliferative, synthesise extracellular matrix elements and exhibit enhanced migratory capabilities. To understand how ACTA2 mutations deregulate VSMC functions and steer them towards a synthetic phenotype, it is necessary to have a cellular model as close as possible to the affected tissue..

summary:
Keratopathy of patients with aniridia leads to epithelial scarring disorders and a progressive clouding of the cornea linked to this abnormal healing (fibrosis). Treatment with autologous serum is usually undertaken to promote epithelial healing.

However, autologous serum does not prevent the formation of fibrosis, whereas growth factor-rich plasma appears to be associated with a reduction in the in vitro expression of fibrosis markers. This study seeks to compare the in vitro healing and anti-fibrotic properties of autologous serum and growth factor rich plasma from aniridia patients and healthy controls.

Studies have shown that health-related quality of life (HRQOL) was worse among patients who underwent surgical eye removal compared to the general population in Denmark.

A third of eye amputated patients suffered from anxiety and depression. Most of the available evidence on the subject is based on retrospective studies that interviewed patients several years after surgery, which can potentially introduce biases.

Moreover, in the literature, there are no data concerning postoperative psychological and visual impact.

title: Cerebellar Superficial Siderosis in Cerebral Amyloid Angiopathy on 1.5T T2*-Weighted Imaging

acronym: CSS

summary: Cerebellar superficial siderosis (SS) has been recently reported to be present in about 10% of both hereditary (n=50) and sporadic (n=46) cerebral amyloid angiopathy (CAA) patients on 3T MRI using susceptibility-weighted imaging (SWI) in the majority of patients. In that study, cerebellar SS was associated with a higher number of supratentorial lobar and superficial cerebellar macrobleeds (although cerebellar SS was not directly located adjacent to these cerebellar macrobleeds). It is unclear if cerebellar SS is caused by in situ leakage of cerebellar leptomeningeal vessels or rather represents hemorrhagic diffusion from cerebellar parenchymal micro/macrobleeds or from supratentorial bleeding sources via the tentorium cerebelli (TC).

title: Effects of Preventive Physiological and Psychological Interventions on Performances During Objective Structured Clinical Examination (OSCE) for Medical Students: Cardiac Biofeedback, Mindfulness, or Inner Resources Mobilization

summary:
Objective Structured Clinical Examination (OSCE) is a newly implemented evaluation standard for medical students and is a determinant part of the national competition they have to undergo.

Exam periods are significantly associated with increased stress and anxiety which led to reduced performance, impaired memorization and impaired workload capacities.

Cardiac biofeedback and mindfulness techniques are efficient methods for stress reduction. Interventions that aim to mobilize competence, such as mobilization of inner strength and resources techniques, should improve the level of preparation of medical students. These three procedures could influence the stress level and improve performance during the OSCE.

There is currently no study exploring the effect of these physiological and psychological procedures on the performance during OSCE for medical students.

title: Influence of Medical Students Coping Behaviour Types on Health Related Behaviour and Stress Level on the Day of the OSCEs

summary:
Objective structured clinical examinations (OSCEs) have recently been incorporated in the French medical studies. They will soon be an important part of the national evaluation of the students, therefore being responsible for a high level of stress.

The differents strategies of coping have never been characterized for this particular group of students. We hypothetize that different strategies of coping are associated with different level of stress, thus being an interesting insight to help students to deal with their stress and prevent disorders linked to stress.

We will be using the Brief Cope Scale to assess the different ways of coping, in addition to multiple demographic and health-related questionnaires.

title: Clinical Efficacy of the Quadratus Lumborum Block for Analgesia in Kidney Transplant Surgery

acronym: CARRENAL

summary:
Kidney transplant is considered as a moderate painful surgery. Unfortunately, patients with chronic kidney disease are not able to degrade opioid drugs and are therefore most likely to be subjected to the secondary effects of their consumption. Current strategies aim to find pain relief substitutes in order to decrease the use of opioids, specially after surgery, during patient recovery. Loco-regional analgesia consists of administering local anesthesic directly in specific nerves and is being used in several surgical procedures. In various abdominal surgeries, a loco-regional analgesia called "tranversus abdominis Plane Block" has been associated with decreased morphine consumption and better post-operative conditions. In kidney transplant, the definitive efficacy of this loco-regional analgesia is not established, due to controversial clinical results.

The goal of our study is to test the analgesia advantage of a variant of the Tranversus Abdominis Plane Block, called Quadratus lumborum block, which targets a muscle called quadratus lumborum, in association with general anesthesia, on post-surgery recovery and opioid intake.


title: Overnight Rostral Fluid Shift in the Pathogenesis of Obstructive Sleep Apnea in Spinal Cord Injured Patients

acronym: OUI-SCI

summary:
Obstructive Sleep Apnea (OSA), a common disorder resulting from repetitive pharyngeal collapse during sleep, is multifactorial. Usually, OSA is considered primarily a problem of upper airway anatomy, with the craniofacial structure or neck fat decreasing the size of the pharyngeal airway lumen. Obesity, male sex and genetics are well established pathogenic factors. In the last decade rostral fluid displacement (fluid shift) to explain the pathogenesis of upper airway collapsibility has been increasingly studied.

Individuals living with spinal cord injury are at increased risk for OSA, with a prevalence that is three- to fourfold higher than the general population. Individual with acute tetraplegia and undiagnosed or untreated OSA may participate less in rehabilitation due to sleepiness and fatigue and therefore be less engaged in activities that improve quality of life and maintain functioning over time. Intermittent hypoxia, sleep fragmentation and alterations of the autonomous nervous system induced by OSA are thought to delay or limit recovery and in the long term, increase cardio- and cerebrovascular morbi-mortality.

Redolfi et al have shown that overnight change in leg fluid volume correlated strongly with the Apnea Hypopnea index (AHI) and the time spent sitting. In SCI patients two mechanisms may underline fluid shift importance in the pathogenesis of OSA: first, time spent sitting is obviously increased in patients with no walking abilities (prolonged sitting position in wheelchair). Secondly, motor deficit lead to the loss of skeletal muscle pumping activity which could promote leg fluid accumulation during the day.

In our knowledge, no study has specifically assessed the impact of rostral fluid displacement on upper airway collapsibility among patients with spinal cord injury.

Better comprehension of upper airway collapsibility determinants in patients with spinal cord injury is mandatory to identify new therapeutic targets (diuretics, contention…) especially since CPAP, the first line treatment for severe OSA, continue to pose adherence issues in SCI patients. In the future, phenotyping OSA patients, especially those with SCI, will improve personalized management.

The main objective is to find if there is a correlation between the apnea-hypopnea index (AHI) and rostral fluid shift overnight, in non-obese spinal cord injured patients. The secondary aim is to find if there is a correlation between AHI and:

Neck circumference
Neck volume
Time spent sitting down

title: [18F]-Fludarabine PET/MR Imaging for the Assessment of Newly-diagnosed Primary Central Nervous System (CNS) Lymphoma : a Pilot PET-MRI Study

acronym: FLUDALOC

summary:
Primary central nervous system (CNS) lymphomas represent 5% of primary brain tumors. More than 90% of them are diffuse large B-cell lymphomas.

[18F]-Fluorodeoxyglucose positron emission tomography (PET-[18F]-FDG) is the gold standard for imaging systemic lymphomas, but its application in primary CNS lymphoma is compromised by the limited specificity of brain fixations and the high uptake of [18F]-FDG in healthy brain tissue.

[18F]-Fludarabine is a new radiopharmaceutical developed for PET imaging of lymphomas. Preclinical studies indicate a restricted binding specificity to lymphoid tissue compared to [18F]-FDG and an ability to detect residual lymphoma disease after treatment. A pilot study in humans shows good agreement of its binding with tumor sites in systemic lymphoma and superior tumor contrast to [18F]-FDG. Finally, a recent preclinical study shows a binding ratio in brain lymphoma 3 times higher than that of healthy brain tissue in mouse models of primary CNS lymphoma, whereas in mouse models of high-grade glial tumors, the binding level is very low, comparable to that of healthy tissue (background). Investigators hypothesize that [18F]-Fludarabine could be the radiopharmaceutical of choice for the diagnosis and monitoring of primary CNS lymphomas in PET.

The main objective of the study is to characterize the cerebral distribution and [18F]-Fludarabine uptake in newly-diagnosed primary CNS lymphomas before surgery, chemotherapy or radiotherapy, using PET-MR imaging.

title: REFLEX: A Randomized Controlled Trial to Test the Efficacy of an Emotion Regulation Flexibility Program With Daily Measures

acronym: REFLEX

summary: The main objective of this RCT is to test the efficacy of an emotion regulation group program (i.e., ART program) in college students, compared to an active control group (i.e., relaxation program). Using multilevel analyses, we expect an improvement in anxious-depressive symptomatology for both groups. However, we expect the ART group to improve specifically on emotion regulation flexibility ability, and the last to be a mediative variable on mental health.

title: Study of Prostate Perfusion Before Embolization in Patients With Symptomatic Prostate Adenoma. A Single-center Prospective Cohort Pilot Study to Determine the Predictive Factors of Clinical Efficacy Associated With a Prior Phantom Study.

acronym: EMBOPERF

summary: Over the last 5 years, prostate embolization has developed as a treatment for symptomatic prostate adenoma. This long, complex procedure is effective in 80% of cases. Currently there are no means of better selecting patients to avoid this long procedure in non-responders. The hypothesis is that prostate perfusion parameters are correlated with the efficacy of embolization. Studying these prostate perfusion parameters in perfusion CT and evaluating prostate Iodine load in dual energy computed tomography will make it easier to select those patients who are most likely to respond.

summary:
Various studies have shown that many patients do not understand all the information provided by the study investigator and by the information sheet before entering a clinical research protocol. Many materials has been developped in previous research, trying to improve patients' understanding. Nonetheless, their effectiveness remains uncertain.

The "LUMINA" project aims to measure the effectiveness of the booklet named "Comprendre les essais cliniques" with patients included or not included in clinical trials within the Clinical Neurosciences - Rheumatology pole of the CHU de Nice. The design of this study is "before/after". A questionnaire was submitted to the patients before and after reading the booklet. That method is used in order to show if there was a difference between the score obtained from the questionnaire before and after reading. This difference could reflect an improvement in patients' comprehension and, by extension, the effectiveness of the support the team developed.

title: The Radiologically Isolated Syndrome International Cohort

summary:
The Radiologically Isolated Syndrome (RIS) corresponds to the discovery of white matter (WM) abnormalities suggestive of multiple sclerosis (MS) by their location, size, and appearance, on the brain or spinal cord Magnetic Resonance Imaging (MRI). This imaging is performed for a reason other than for suspicion of demyelinating disease in subjects without a history of neurological symptoms and a strict routine clinical neurological examination. It was defined and named in 2009 (Okuda et al.) after publishing 3 case series (French, USA, Turkey). The Radiologically Isolated Syndrome Consortium (RISC) published a cohort of subjects with an extended follow-up after the first brain MRI of MS, with 34% presenting an event (clinical conversion) at five years, 51.2 % of these subjects showed an event at ten years. The patients who offer a higher risk of developing a first clinical demyelinating event were identified such as male sex, young age, the presence of oligoclonal bands (BOCs) in the Cerebrospinal Fluid (CSF), the presence of infratentorial lesions and spinal cord lesions on the first MRI suggestive of RIS. The location and morphology of the lesions appear to be decisive for studying the risk of conversion. Our first objective is to prospectively collect data to identify the subjects who present a higher risk of developing a first clinical demyelinating event and the progression of the disease in these subjects.

Among the objectives of this worldwide cohort is the analysis of (1) environmental factors (Vit D, EBV, tobacco…), (2) MRI biomarkers, including atrophy, central veins signs, paramagnetic rings, and DTI.

(3) digital biomarkers (4) oculography (5) biological markers To summarize, this cohort will allow for analyzing features in imaging, biology and the exploration of digital and oculographic characteristics to identify predictive factors of clinical evolution of a large cohort of subjects presenting WM abnormalities suggestive of multiple sclerosis.

summary: The Radiologically Isolated Syndrome (RIS) is defined as incidental Magnetic Resonance Imaging (MRI) abnormalities fulfil the criteria for dissemination in space, suggestive of multiple sclerosis. Nowadays, mandatory vaccination in patients with multiple sclerosis (MS) is widely recommended. Regarding COVID19, the absence of specific warnings led to the proposal of vaccination in patients with inflammatory diseases of the central nervous system. We aimed to evaluate if COVID19 vaccination or infection increased the risk of clinical conversion to multiple sclerosis or evidence of disease activity (EDA) in a cohort of RIS subjects.

title: INNOVATIVE TREATMENT OF SCARRED VOCAL FOLDS BY LOCAL INJECTION OF AUTOLOGOUS ADIPOSE-DERIVED STROMAL VASCULAR FRACTION: EFFICACY VERSUS PLACEBO

summary:
Vocal Folds scarring (whether congenitally or following phonosurgery) can result in a range of symptoms depending on severity and extent, such as hoarseness, breathy voice, increased effort to speak, and voice fatigue. The inability to phonate normally causes both physical and psychological disability, especially for professional communicators (teachers, tradesmen, singers, etc.). There are several therapies currently available but these are often disappointing, as the great complexity of vocal fold microstructure hinders the development of effective therapy. Thus, identification of innovative strategies able to improve vibrational mechanical properties of vocal folds remains an important clinical challenge.

Autologous Adipose-Derived Stromal Vascular Fraction (ADSVF) is recognized as an easily accessible source of cells displaying angiogenic, anti-inflammatory, immunomodulatory and regenerative properties. Recent experimental and clinical reports also supported the anti-fibrotic potential of ADVSF, mainly attributed to the mesenchymal stem/stromal cell subset.

Safety in humans has already been confirmed in several studies, including our previous clinical trial (ClinicalTrials.gov NCT0262246; EudraCT number: 2015-000238-31). The main objective of this phase I/II trial was to measure for the first time the safety and tolerability of autologous ADSVF local injections in patients with scarred vocal folds. No severe adverse events occurred: only some minor adverse events were reported. Moreover, Voice Handicap Index was improved in all patients with a mean improvement from baseline of 40.1/120 and seven patients were considered as responders, defined as an improvement ≥ 18 points.

Based on these observations, we hypothesized that the injection of autologous ADSVF could reduce the process of fibrosis, improve vibration and then dysphonia and quality of life in patients with scarred vocal folds.

In the absence of a reference treatment, the effectiveness of the ADSVF will be compared to a placebo: the local injection of excipients solution.

This study will test efficacy of the autologous ADSVF to treat vocal folds scarring. It is a randomized, double-blind, phase II clinical trial conducted according to a 2-treatment parallel design, with medico-surgical and scientific collaboration.

Recruitment and follow-up of patients will be done in 4 university hospitals by the respective ENT teams (Marseille, Toulouse, Nice and Montpellier): 36 patients will be recruited and treated on a 24 months period.

At inclusion, 36 patients will be randomized (1:1 ratio) into two groups: ADSVF group and placebo group. Adipose tissue removal, ADSVF production and injection of ADSVF or placebo will be done on the same day during a short hospital stay. Patients will be followed and evaluated at 1 and 6 months with self-evaluation (Voice Handicap Index and a 10 points scale), video-laryngo-stroboscopic examination, vocal assessment with perceptive, acoustic and aerodynamic parameters and evaluation of adverse events. At the end of this 6-month follow-up (primary endpoint), patients without improvement will be offered an injection of thawed and washed ADSVF. Patients will continue to be followed in open-label on the same endpoints.


title: Impact of Opioids on Heart Rate During Rapid Sequence Intubation: Double-blind Randomized Controlled Study

acronym: CANDY-CRASH

summary:
The patient is seen upstream by an anaesthetists resuscitator (MAR) in order to carry out his anesthesia consultation. If the patient meets the eligibility criteria he will be informed of the study and his signed consent will be obtained.

Patients will be divided into 3 parallel groups :

Group A (placebo +remifentanil)
Group B (sufentanil + placebo)
Group C (placebo + placebo)

Constants are taken at T0. A non-invasive continuous monitoring (Clearsight ©) will be used to collect data: blood pressure, heart rate, cardiac output.

To ensure double-blinding the nurse who prepares the syringes is not part of the anesthesia team. He/she numbers them in syringe n°1 and n°2 to indicate the order of injection to the MAR.

The MAR injects the drugs according to the standardized study plan (see below):

T1: the patient receives an intravenous bolus (IV) over 5 seconds of molecule n°1
3 minute delay
Patient receives Etomidate 0.3 mg/kg IV over 10 seconds
5 second delay
The patient receives an IV bolus over 30 seconds of molecule n°2
5 second delay
The patient receives Succinylcholine or Rocuronium IV over 5 seconds
T2: End of induction, oro-tracheal intubation (= T2)

The laryngoscopy is performed by an experienced MAR or nurse (IADE). The end of the intubation is defined by the fixation of the intubation tube (T3). Hemodynamic parameters are measured every minute for ten minutes after intubation (T4 to T13).

Maintenance of anesthesia is standardized with halogen gas (SEVOFLURANE) and an opioid (SUFENTANIL). Ten minutes after the patient's intubation (T13), the blind is lifted, allowing the addition of sufentanil in groups A and C before any surgical procedure.
