MECHANISMS OF NEURONAL RESILIENCE IN ALZHEIMER'S DISEASE AND ITS FOCAL VARIANTS: A PET/MR STUDY

Patients with Alzheimer's disease and with early onset of symptoms (\<65 years) (AD-Y) have a multi-domain cognitive deficit, whereas memory disorders (typical of the elderly patient's AD) are less often in the foreground. In addition, some MA-J have an atypical phenotype indicating focal brain damage, although they have the same pathological lesions: amyloid deposits and tau protein deposition (DNF). This is the case of posterior cortical atrophy (PCA) characterized by complex visual disturbances and atrophy affecting the more posterior regions of the brain. Based on the clinical profile of PCA patients, a more refined anatomo-clinical classification was proposed, distinguishing a rather "ventral" form and a rather "dorsal" form. The recent arrival of tau-specific PET tracers now makes it possible to evaluate in vivo fibrillary neurodegeneration (FND), which is well correlated with the severity of cognitive disorders. Advances in MRI have shown that each neurodegenerative syndrome targets a large-scale neural network, which in turn shows a vulnerability for a specific biological disease. In the case of AD, the reason for such a difference in cognitive and anatomical impairment between patients with diffuse involvement and others with more focal involvement is not known. One possible explanation is the existence, in focal forms, of neuronal mechanisms that oppose vulnerability. These mechanisms may correspond to the so-called "resilience" phenomenon, defined as resistance to a neuropathological process by the ability to optimize cognitive performance via the efficient recruitment of neural networks. The mechanisms underlying resilience in neurodegeneration are unknown. Their identification is very important for the management and treatment of AD.

Virological Surveillance of Acute Respiratory Infection in Primary Health Care in Metropolitan France

Every year in the fall and winter, numerous respiratory viruses (such as influenza viruses, SARS-CoV-2 (COVID-19), RSV, rhinovirus, and metapneumovirus) circulate in mainland France, causing acute respiratory infections (ARIs). These viruses can cause epidemics of varying severity, requiring close monitoring to determine their circulation levels and adapt public health measures accordingly. In France, ARI surveillance relies on two networks: the Sentinelles network in primary care and the RENAL network in hospitals. The Sentinelles surveillance is conducted in collaboration with Santé publique France, the National Reference Center for Respiratory Infection Viruses (Institut Pasteur and Hospices Civils de Lyon), and the University of Corsica. As part of the virological surveillance of ARIs, Sentinelles physicians are asked to collect nasopharyngeal swabs or saliva samples from a sample of patients presenting with an ARI during their clinic visits. This surveillance makes it possible to identify respiratory viruses circulating in primary care (general practice and pediatrics), to describe confirmed cases for each of the circulating viruses, and to estimate the impact of each on general practice. This surveillance also allows for the evaluation of the effectiveness of vaccines against influenza and COVID-19.

Investigating Vascular Properties of HEMI and SPG Signals in Individuals With or at Risk for Chronic Kidney Disease

This prospective, single-center clinical investigation conducted in France will evaluate two non-invasive investigational devices (HEMI and SPG-NINOX) designed to assess microcirculation in adults. The study will include 165 participants divided into five groups (33 per group): healthy volunteers, patients with hypertension without chronic kidney disease (CKD), patients with type 2 diabetes without CKD, patients with moderate CKD, and patients with severe CKD. The primary objective is to compare baseline small vessel pressure measured with the HEMI (Multi-spectral optical system for microcirculation hemodynamics) device across groups in order to identify microvascular alterations associated with cardiometabolic and renal disease. Secondary objectives include assessment of microvascular responses after post-ischemic hyperemia, evaluation of SPG-derived (Speckle plethysmography) small vessel flow and volume parameters, comparison with reference vascular measurements (including SphygmoCor and ultra-high frequency ultrasound), and evaluation of feasibility, acceptability, and measurement reproducibility. Participation is non-randomized, based on participants' pre-existing clinical condition, and study procedures are non-invasive with an expected visit duration of approximately 60 minutes.

Nutrition, Gut Microbiota and Health : Feces Sample Collection in NutriNet-Santé Participants

The gut microbiota is currently attracting increasing attention from the scientific community and also from the general public, as evidence of its role in human physiology has been highlighted. Microbial signatures have also been associated with various pathologies (e.g. obesity, diabetes, gastrointestinal disorders, neurodegenerative diseases), but the causality of these associations is still uncertain. Among the factors that may influence the composition of the gut microbiota (e.g. lifestyle, hygiene, medication, genetics, environment), nutrition would a major role. The major changes in lifestyle and diet observed over recent decades are strongly suspected of disrpting the host-gut microbiota balance. In addition to their nutrient content, our diets also contain other bioactive compounds (e.g. polyphenols) and raise new issues (e.g. temporal structure of diets, food processing, presence of additives or contaminants such as pesticide residues, intake of dietary supplements, dietary exclusions, glycemic index) that is necessary to take into account. Thus, it is mandatory to explore and characterize in a more precise way, within large samples consisting of individuals with varied characteristics, the way in which the composition of the gut microbiota is influenced by the host's diet and its health consequences. The aim of this research is therefore to study the links between nutrition, gut microbiota profiles and health. To do this, the research will implement large-scale stool sample collection from participants in the NutriNet-Santé cohort ("Nutrinautes"), thus constituting a "microbiota" sub-cohort. A target of N=10,000 participants in the NutriNet-Santé cohort will be recruited on a voluntary basis. A selection will then be made among Nutrinautes willing to participate in the research (which may be more numerous than necessary) to maximize the diversity of profiles. Participants will be informed of their selection or non-selection by e-mail. A second stool sample will also be collected 2-3 months after the first for a sub-sample of N=300 to assess intra-individual variability in microbiota profiles. The selected participants will receive a stool self-sampling kit with detailed instructions by post to their home address. The pseudonymized samples will be returned by mail by the participant to the processing laboratory, which will determine their gut microbiota characteristics by 16S rDNA sequencing and/or " shotgun " sequencing. The gut microbiota profiles will then be analyzed in a pseudonymised manner in association with diet and health, using data collected as part of the NutriNet-Santé cohort follow-up (e.g. food consumption, prevalence and incidence of pathologies, biological data, anthropometric characteristics, medication intake, socio-demographic characteristics, lifestyle).

Bronchial Epithelium of Children With Post-infectious Bronchiolitis Obliterans

Bronchiolitis obliterans (BO) is an irreversible chronic obstructive pulmonary pathology leading to obstruction and/or obliteration of the small airways. In children, the most common form of BO occurs following a serious lower respiratory tract infection. This is a rare complication; the incidence is unknown. The diagnosis, often late, is made on clinical, spirometric and radiological arguments. The pathophysiology would be linked to damage to the airway epithelium. PIBO is most commonly associated with adenovirus (ADV) infection (serotypes 3, 7, 11 and 21) but also other viruses such as rhinovirus (RV). The treatment of PIBO is not clearly established, it remains empirical. The research hypothesis is that the morphology of the nasal epithelium of children with ADV or RV infection is different for those progressing to PIBO. The main objective of the proposed observational study is to characterize damage to the respiratory epithelium in these children. This is a single-center prospective longitudinal study (AP-HM), in children aged 1 month to 6 years, comparing children hospitalized for lower respiratory infection by ADV or RV progressing or not to PIBO. All children included will have a nasal swab and brushing on D0. Children developing PIBO will have nasal brushing with bronchial endoscopy with bronchial biopsies and bronchoalveolar washing at the time of PIBO diagnosis and again at M6 in case of partial response to treatment. This is therefore a pilot study aimed at defining damage to the respiratory epithelium in children with PIBO following an ADV or RV infection and the role of respiratory epithelial cells in PIBO.

Prenatal Maternal Mental Health and Neurodevelopment in Congenital Heart Disease

Congenital heart disease (CHD) is the leading cause of congenital malformations, representing 1% of live births. Progress in surgical care have led to the dramatic increase in the population of children and adults living with heart disease. As survival is no longer a concern, long-term outcomes have become the major public health issue. Prenatal diagnosis of CHD requiring open-heart surgery can be a traumatic event for expecting mothers and fathers. In the general population, maternal mental health distress is associated with fetal disturbances in the hypothalamic-adrenal-pituitary system axis, restricted intrauterine growth and adverse outcomes in the offspring. It is unknown whether prenatal maternal psychological distress have an impact on neurodevelopmental outcomes in CHD. Our national study seeks to (1) characterize the impact of prenatal maternal psychological distress on neurodevelopmental outcomes at age 1 for children with CHD who undergo neonatal open-heart surgery; (2) investigate the sociodemographic and medical determinants associated with prenatal maternal mental health of women carrying a foetus diagnosed with complex CHD; (3) explore the mediating role of prenatal risk factors (i.e., sociodemographic, medical and maternal coping mechanisms) in the association of prenatal maternal mental health (i.e., distress, anxiety and depression) and neurodevelopment in children with CHD; and (4) explore the impact of paternal or the co-parent's mental health impact on neurodevelopmental outcomes at age 1 in children with CHD. This study is a non-interventional, prospective, and longitudinal study of prenatal maternal mental health and subsequent child's neurodevelopmental and behavioural outcomes. It includes a follow-up period from the 3rd trimester of pregnancy until the child's first year of life. It will include children with a prenatally diagnosed heart defect requiring open-heart surgery within the first weeks of life. Understanding and preventing the neurodevelopmental sequelae of heart disease diagnosed in-utero is a public health priority.

Investigation of AlzHeimer's Predictors in Subjective Memory Complainers - Extension Study

A regional, single-center, prospective, observational academic cohort will follow subjects who previously participated in the INSIGHT study and who agree an extension of their follow-up in the INSIGHT-2 research for additional 5-6 years. An annual multimodal evaluation (cognitive, oculomotor, biological and neuroimaging) will be proposed in order to describe the natural history of preclinical Alzheimer's disease (AD). The primary endpoint is the conversion to the symptomatic stage in subjects at risk, identified by positive amyloid staining (A+) on florbetapir positron emission tomography (PET) imaging. The size of the cohort is estimated to around 240 participants (61 A+ subjects) among the 318 participants included in the main cohort (88 A+ subjects). The follow-up in the INSIGHT-2 cohort will be lightened compared to that of the main cohort with an annual frequency of visits rather than a six-monthly one.

MRS of Glioma Genomics

In France, about 5000 new people with a primary malignant brain tumor are diagnosed each year. The most common primary tumors are gliomas, originating from glial cells (astrocytomas and oligodendrogliomas). Low-grade gliomas are mildly aggressive, but they often evolve into a more malignant form. Mutations in the genes encoding isocitrate dehydrogenase (IDH) are found in about 80% of low-grade gliomas and are associated with a favorable prognosis. Remarkably, IDH-mutated gliomas are characterized by a specific cellular metabolism causing the accumulation of D-2-hydroxyglutarate (2HG) in tumor cells. 2HG can be detected in vivo using 1H magnetic resonance spectroscopy (MRS) and is recognized as a unique, noninvasive biomarker of IDH-mutated gliomas. Noninvasive detection of IDH mutations via 2HG MRS represents a crucial step for decision-making and patient care. A subset of IDH-mutated tumors also presents a complete deletion of 1p and 19q chromosome arms (1p/19q codeletion). The 1p/19q codeletion is specifically linked to the oligodendroglial histologic subtype and it has been associated with a better patient outcome. However, the biological effects of this genetic alteration are still unclear and in vivo markers are lacking. Recently, we reported the first in vivo detection of the cystathionine molecule in human brain gliomas using MRS and explored the association between cystathionine accumulation and 1p/19q codeletion in gliomas. In this project, the investigation team will combine cutting edge MRI and MRS techniques for metabolic and microstructural characterization of brain tumors with the aim of providing novel reliable noninvasive biomarkers of tumor genetic subtypes. These methods will enable noninvasive identification of IDH-mutated gliomas and, potentially, 1p/19q codeleted gliomas. In addition, the researchers will investigate the utility of 2HG, cystathionine and MRI microstructural markers to monitor tumor response to anti-cancer treatments and tumor progression. The outputs of this project, altogether, may open new avenues to a better understanding of the pathophysiological mechanisms of oncogenesis and the design of new treatments for gliomas.

Identification of Early Markers for ALS

Although several molecules have been proposed as biomarker candidates, a clinically established signature for an early or even premotor diagnosis of ALS is not available. Due to the already advanced, disease stage at the time of diagnosis as well as rapid disease progression, an early diagnosis is mandatory for efficacious disease-modifying therapies. In this project, the investigators will develop a clinical molecular fingerprint of PGMC that will provide insight into the molecular pathogenesis of ALS and allow earlier diagnosis.

Study of the Correlation Between Cortical Excitability and Cytoarchitectonics of Prefrontal Cortex in Healthy Adult Participants, Using Transcranial Magnetic Stimulation Coupled to EEG and High-field MRI

Repeated transcranial magnetic stimulation (rTMS) is mainly used to treat mood disorders by addressing differences in brain function, particularly in the dorsolateral prefrontal cortex (DLPFC), which affects emotions and executive functions. The therapy aims to enhance the left DLPFC or suppress the right. It has been approved for severe major depression in several countries (Canada and Israel since 2002, USA since 2008) and is in the process of being validated in Europe but is not yet reimbursed in France. due to variable results from one study to another and lack of standardization issues. In a previous study, by recording electroencephalographic (EEG) rhythms before and after rTMS treatment of the DLPFC, the investigators showed on a small cohort of patients (n=17) with major or bipolar depression, that the responder patients showed higher EEG theta rhythms in the DLPFC but also and especially in parietal regions. This suggests that the DLPFC is part of the fronto-parietal central executive network (CEN), which is important for working memory and cognitive control. The CEN is not well connected in severe resistant depression, possibly leading to negative emotional bias. The rTMS cure of DLPFC can be interpreted as improving depressive symptoms through the normalization of the CEN by increasing DLPFC excitability and its downward connectivity. However experimental and clinical evidence for this mechanism, among others, is still to be demonstrated, and remission rates of rTMS from DLPFC in drug-resistant depression are still low (20-40%). To improve these response rates to rTMS in DLPFC, it is essential to continue research aimed at improving clinical practices through a better knowledge of the functional neuroanatomy and mechanisms of action of rTMS. This will require the definition of biomarkers allowing in particular to better target the DLPFC, this structure beeing indeed relatively poorly defined on the neuroanatomical level (large portion of the medial frontal gyrus). To this end, the investigators have set up a collaborative research program with Dr. Corey Keller, psychiatrist at Stanford University USA, which was jointly funded in 2022 by the Agence Nationale pour la Recherche (ANR) and the National Institute of Health (NIH) - FrontalProbe project "Probing the dorsolateral prefrontal cortex and central executive network for improving neuromodulation in depression". The ultimate aim of this project is to develop and test different strategies for targeting the DLPFC in the rTMS treatment of pharmaco-resistant depressive patients, following the fundamental neuroanatomical and pathophysiological hypothesis that patients will respond better to therapy if their CEN network is better modulated. This clinical trial will take place in Stanford, USA, in the years 2025-2026. Previously, the investigators are working on the development of methodological strategies aimed at preferentially activating, in a personalized way, the part of the DLPFC that projects onto the PPC. This is the subject of the present protocol, which aims to identify this subpart of the DLPFC to be targeted as a priority for modulating the CEN, through neuroanatomical measurements with high-field MRI and cortical excitability by TMS-EEG in healthy subjects. To this end, the investigators will use a small cohort of healthy subjects who will have one multimodal MRI acquisition session of at 7T and one TMS-EEG session. The 7T MRI data, acquired at the Centre de Résonance Magnétique en Biologie et Médecine (CRMBM), will be used to obtain anatomical markers of the DLPFC. TMS-EEG data, acquired at the Institut de Neurosciences de Systèmes (INS), will be used for cortical excitability measurements of the DLPFC and its projection sites, notably the PPC. At this stage, no data exchange is planned with our American partners. Firstly, the processing of MRI data will include segmentation of gray and white matter, reconstruction of the cortical surface and estimation of the different cortical layers, mainly by monitoring variations in the T1 parameter along the cortical mantle. Other MRI parameters will also be acquired to maximize the specificity of the segmentation of the DLPFC into sub-regions, firstly by identifying the part of the DLPFC that connects preferentially to the PPC using the reconstruction of fiber bundles from diffusion MRI and functional resting MRI. Secondly, during TMS-EEG acquisitions, participants will be stimulated in 3 sub-regions of the DLPFC. For each target, the analyses of the EEG data will focus on quantifying connectivity with the PPC as well as their spectral signature, which is possibly an indirect reflection of the neuronal composition of the stimulated regions. Correlation of 7T MRI and TMS-EEG data will help set optimal DLPFC targeting criteria for PPC activation. The aim is to create an MRI-based targeting procedure for clinical practice. In this sense, TMS-EEG will serve as validation of MRI markers.

Identification of Cellular Biomarkers of Rare Eye Diseases in Adults

The cornea is the outermost transparent 'window' of the eye allowing light to enter and serving as the first-line immune and mechanical barrier. It is a complex avascular tissue composed of cells, stem cells, nerves, and collagen layers organized in an exquisite manner to maintain its transparency and self-healing capacity. This delicately balanced interplay of corneal elements is disrupted in rare diseases of the cornea, resulting in non-healing wounds, corneal ulceration, inflammation, new vessel ingrowth (neovascularization), defective innervation, scarring, oedema and loss of transparency. For many Rare Eye Diseases (REDs), drug development has been relatively unsuccessful, delivering few to no new therapies. Current management is often prohibitively expensive, has low efficacy and leads to debilitating side effects. The RESTORE VISION project (https://restorevision-project.eu/) aims to improve eye health by using cutting-edge models for each rare disease to test novel and repurposed compounds (9 in total) and determine drug mechanisms of action, formulating compounds as safe eye drop suspensions, and performing several first-in-human trials of novel therapies. Thes drugs have solid preliminary data showing beneficial effects in restoring the cell physiology, immune, avascular, neural and signaling environment in the cornea. The current clinical study is part of Work package 2 within the RESTORE VISION EU grant agreement (''Validation of human drug targets of repurposed drugs and novel therapies'') and aims to ascertain the expression levels of genes and proteins and investigate pathways of interest in human tissue and fluid samples of REDs, that are targeted by the proposed experimental/repurposed substances. Therapeutic target gene and/or protein expression will be verified in human blood, tears and conjunctival cells collected from 7 RED patient groups. The RESTORE VISION Consortium know multiple putative genes and proteins involved in the REDs and/or affected by the drugs to be tested in RED models. These will be analyzed in patient samples from the 7 REDs to see if they are 1) expressed at all; 2) differ in expression between patient and control group and 3) are correlated with clinical endpoints and/or symptoms of REDs. The 7 REDs under investigation are briefly explained as follows: 1. AAK: genetic progressive limbal stem cell degeneration leading to corneal neovascularization, inflammation, recurrent erosions, chronic pain and vision loss. 2. OCP: autoimmune scarring of the conjunctiva leads to deficient wound healing, inflammation, scarring, blindness and pain. 3. EEC Syndrome: Ectodermal Dysplasia causes pathological corneal scarring and blindness. 4. NK: involves a corneal nerve deficit leading to reduction or loss of corneal sensitivity, impaired wound healing, corneal ulceration and loss of vision. 5. LSCD: acquired or hereditary stem cell deficiency inducing epithelial breakdown, neovascularization, scarring and inflammation leading to decreased vision, tearing and pain. 6. oGvHD: a severe side-effect of successful bone-marrow transplantation leads to painful and blinding ocular surface inflammation, neovascularization and delayed wound healing. 7. CN: in high-risk transplantation, pathologic inflammation, corneal blood and lymphatic vessels are key risk factors for high-risk corneal graft failure, leading to graft rejection and blindness.

MOLECULAR BASIS OF LANGUAGE DEVELOPMENT AND ASSOCIATED DISORDERS

Developmental Language Disorder (DLD) refers to children who present with language difficulties that are not due to a known biomedical condition or associated with autism spectrum disorder (ASD) or intellectual disability. The prevalence of DLD is \~7%-8% or 2% if severe forms are considered. However, the clinical heterogeneity of language disorders, the presence of co-morbidities and the inconsistent terminology used for many years have hindered research and clinical practice. Distinguishing sub-groups of children with language problems is crucial when tackling the underlying genetic causes of this disease. Recently, several studies using high-throughput sequencing have better define the genetic basis of CAS but such studies focusing on DLD are limited. The investigation of more homogeneous cohorts of individuals that clearly distinguish DLD cases, from ID and not including children with CAS should improve our understanding of the genetic basis of this disorder. In this study, we aim to built and investigate a well-characterized cohort of DLD patients using pangenomic approaches to better define the molecular basis of this disorder. All individuals will be analyzed using chromosomal microarray analysis and whole genome sequencing. Multiple observations and preliminary results suggest strong links with the genetic basis of other neurodevelopmental disorders. The goal is to identify CNV or SNV as causative allele or risk factor and already known to be involved in other neurodevelopmental disorders as well as potential new variants.

Genetic Susceptibility to Severe Infections

Only a fraction of individuals infected with microbes develop clinical disease. This observation raises fundamental questions about the pathogenesis of infectious diseases. There is a complex interaction between environmental (microbial and non-microbial) and human (genetic and non-genetic) factors. This will determine the quality of the immune response against the infectious agent and the clinical manifestation. By definition, individuals who die from an infection have defective immunity to the pathogen in question (immune agent (immune deficiency). The investigation of individual variability in the development of infectious diseases began in the early 20th. The first evidence to support the hypothesis that individual variability variability and immune deficiencies were hereditary came from observations of familial cases or genetic isolates genetic isolates (from a homogeneous population) of rare or common infectious diseases, which in some cases Mendelian heredity hat predisposition to infectious diseases runs in families even more so than diseases associated with less determined environmental factors, such as certain cancers. such as certain cancers. Finally, studies comparing the rate of concordance of infectious diseases between monozygotic and dizygotic twins also implicate genetic factors in disease susceptibility. These observations were validated by the discovery of genetic defects associated with severe infectious diseases, leading to proof of concept. While a number of hereditary immune deficiencies associated with susceptibility to multiple pathogens or microorganisms, a growing number of new and rare new and rare immune deficiencies conferring restricted susceptibility to infections caused by a single caused by a single pathogen family, or even a single pathogen, in otherwise healthy children, have recently been identified (one gene, one pathogen). As a result, a dozen Mendelian clinical syndromes characterized by restricted susceptibility are now known. Over the last 20 years, it has been proven that these "idiopathic" infections were immune deficiencies. The investigators now wish to study new severe infections, including but not limited to viral, fungal and bacterial infections. viral, fungal, bacterial and parasitic infections. This should lead to a better understanding of the pathophysiology of each disease, the development of new therapeutics and better patient care.

National Cohort on Congenital Defects of the Eye

Congenital malformations of the eye comprise various developmental defects including microphthalmia, anophthalmia, aniridia, and anterior segment anomalies (such as Peters and Axenfeld-Rieger anomalies). These malformations are frequently associated with extra-ocular features and intellectual disability. However, little is known about visual outcome, frequency and consequences of extra-ocular features in patients. The originality of the project will be to include a spectrum of malformation thought to be a phenotypic continuum (anophthalmia, microphthalmia, aniridia, anterior segment dysgnesis). In addition, we aim to conduct a 10 year follow-up of these children, thus allowing determining ocular and neurological outcomes as any other medical event. We should also be able to determine phenotypic factors that would be associated with good or poor visual and neurologic outcomes

European Cystinosis Cohort

Cystinosis is a generalized lysosomal storage disease with a reported incidence of about 1:180,000 live births. There are estimated 110-140 cases in France (approximately 500 in Western Europe). The disease is caused by mutations in the CTNS gene coding for cystinosin, a lysosomal carrier protein. The lysosomal cystine accumulation leads to cellular dysfunction in many organs. The first symptoms start at about 6 months of age. In the absence of specific therapy, end stage renal disease occurs between 6 and 12 years of age. Survival beyond this age is associated with the development of extra-renal complications. Renal transplantation and the availability of cystine-depleting medical therapy, cysteamine (EU/1/97/039/001, EU/1/97/039/003), have radically altered the natural history of cystinosis. Cystinosis is a good example of a "paediatric" disease where patients now survive into adolescence and adulthood. These individuals have complex, multisystem problems that require on-going care. Despite some progress in recent years there are still significant limitations in the knowledge of diagnostic and therapeutic procedures. A first European registry was launched in 2011, using the CEMARA application developed by the Banque Nationale de Données Maladies Rares (BNDMR, CNIL authorisation number: 1187326), allowing the collection of data from France, Belgium and Italy. The objective of the current study is to translate this database into a cohort study that will allow and facilitate the collection of a wider range of data including clinical, and personal data such as quality of life data, from an increased number of European countries, improve the monitoring, data-management and analysis of the data, offer the possibility for patients to actively participate to and benefit from the study by developing a module in which patients will enter their own data on quality of life with a direct feed-back on the general results. This project is a unique opportunity for building a consensual European academic cohort not based on company driven, "drug-oriented" objectives. The cohort will collect clinical details to analyse patient outcomes thus providing audit of patient care \& clinical effectiveness. It will be possible, through the cohort, to indicate where improvements need to be made and ultimately improve care to the highest standards.

Neuroplasticity After Proprioceptive Rehabiliation

Sequences of muscle tendon vibrations allow to reproduce the sensory feedback during movement like locomotion and kinaesthesia. It is known that such a treatment promotes motor recovery after stroke assuming that it enhances neuroplasticity. The aim of the research is to study the activity in cerebrospinal circuitry to evaluate the neuroplastic changes during and after instrumented proprioceptive rehabilitation relying on sequences of muscle vibration in subacute stroke stages.

European Cystinosis Cohort 2

This European observational cohort follows patients with cystinosis, a rare lysosomal storage disease caused by CTNS mutations leading to cystine accumulation and multisystem involvement. It aims to describe the long-term clinical course under current treatments, focusing on renal and extra-renal complications, survival, and quality of life. It also evaluates treatment effects and explores biomarkers, including inflammatory markers, with biobanking for future research.
