In this study, data from patients with INS will be recorded prospectively, regularly and systematically. The cohort will be composed of patients followed by pediatric nephrologists affiliated with the SNP. Metropolitan France, Reunion Island and Mayotte are the geographical areas concerned. It is planned to integrate other French overseas departments and territories, in particular the West Indies. This is therefore a prospective, multicenter, cohort follow-up study. The data will be centralized via a secure website dedicated to the study. Data will be obtained from: * Medical record data (hospitalization/consultations) as part of routine clinical follow-up for patients with active disease. This information will be medically validated and integrated into the database with the help of clinical research staff. * A telephone interview for annual follow-ups for patients whose absence of active disease no longer requires a systematic medical visit. This structured interview will be administered by telephone by the study's clinical research staff. * Self-administered or hetero-administered quality of life questionnaires (PEDS-QL), self-administered or hetero-administered treatment compliance questionnaires (Morisky's Score), and questionnaires on the aesthetic impact of treatments (Ferriman's Score). These questionnaires will be centralized and reported to the database by the study's clinical research staff.

It is an open label phase III randomized controlled clinical trial comparing 2 arms: * Control arm A consists in TNT regimen, with an induction chemotherapy Modified FOLFIRINOX (mFOLFIRINOX) 6 cycles over 12 weeks, followed by nCRT 50 Gy over 5 weeks with concomitant capecitabine (CAP50 Gy). * Experimental arm B consists in addition of three fractions of CXB every two weeks between end of mFOLFIRINOX and nCRT. Clinical, endoscopic and radiological evaluation will be performed 7 weeks after the end of nCRT in both arms: * In case of cCR, local excision or surveillance will be proposed to patients regarding center choice * In the absence of cCR patients will be treated by TME, followed by adjuvant chemotherapy (mFOLFOX 6 cycles or capecitabine 3 cycles over 12 weeks).

The clinical evaluation demonstrates that the clinical benefits, performance and safety of the Lync® device when implanted in the toes for the treatment of arthritis are not covered by any clinical data on similar devices. The "LYNC" clinical investigation aims to confirm the clinical benefits, performance and safety of the Lync® device on 76 cases (feet) when implanted in the toes for the treatment of arthritis and correction of bone misalignments. The main objective of the study is to confirm the clinical benefits of the Lync® device for the treatment of arthritis and the correction of bone alignment default, by evaluating the restoration of the functional capacities of the forefoot at 3 -4 months post-operative follow-up with AOFAS-LMIS score as primary endpoint. The secondary objectives of the study are: * To confirm the clinical benefits of the Lync® device for the treatment of arthritis and the correction of bone alignment default in the toes, by evaluating the reduction in patient pain during the 3-4 month postoperative visit. * To confirm the clinical performance of the Lync® device for the treatment of arthritis and the correction of bone alignment default in the toes, by evaluating the radiographic parameters (bone consolidation) during the 3-4 month postoperative visit. * To confirm the safety of the Lync® device for the treatment of arthritis and the correction of bone alignment default in the toes, by evaluating the occurrence of adverse events, complications and device defects at the various postoperative follow-up visits. The secondary endpoints associated with the secondary objective are: * The change in the VAS score will be evaluated at the postoperative visit at 3-4 months compared to that at the preoperative visit. * The assessment of bone consolidation will be carried out at the post-operative visit at 3-4 months. An additional visit at 6 months, assessing bone union, will be carried out ifbone union has not occurred 3-4 months post-operatively, in accordance with theinvestigators' current practice. * The collection of adverse events and defects will be done throughout the follow-up by the surgeons thanks to questioning of the patient, assessments of clinical and radiographic examinations of the foot.

This study does not require additional examination, and will use the data performed from the minor salivary gland biopsy carried out as part of usual care, in comparison with the results of the conventional histopathological examination.

The KDOQI 2020 - Clinical practice guideline for nutrition in chronic kidney disease (CKD) -recommends protein restriction to reduce the risk of end-stage renal disease/death and improve quality of life, a low protein diet providing 0.55-0.60g dietary protein/ kg body weight/day is recommended. FLAVIS® is a product line of hypoprotein foods specially developed for the treatment of CKD.The use of low-protein foods may facilitate the achievement of nutritional goals in terms of protein intake and help patients to follow a low-protein diet.

Numerous neurological disorders affecting the central and peripheral nervous system can be attributed to the immune system through multiple effector mechanisms. However, current treatments could be drastically improved by faster and more accurate diagnosis. The sample collection will benefit to patients with rare neuroimmune syndromes such as Autoimmune Encephalitis (AE) and Paraneoplastic Neurological Syndromes (PNS) leading to a better and early diagnosis, as well as treatment improvement.

Colorectal cancer occurs mainly in elderly patients. Recent estimation showed that in France more than 50% of the patients diagnosed with a colorectal cancer are 70 years old or more. Adjuvant chemotherapy has demonstrated a benefit on disease-free survival and overall survival after a stage III colon cancer resection. Nevertheless adjuvant chemotherapy is poorly used in elderly patients. Prognostic improvement with chemotherapy based on 5FU is suggested by a post-hoc analysis of randomized prospective clinical trial. But elderly patients in this study were highly selected and patients older than 80 represented only 0.7% of the total population. Thus, there is still a concern about the benefit of adjuvant 5FU-based chemotherapy in very elderly unselected patients. The recommended treatment for stage III adjuvant chemotherapy is a combination of fuoropyrimidine and oxaliplatin. Nevertheless oxaliplatin did not demonstrated survival advantage in elderly patients. Altogether there are still two matters of debate: * First, is there a benefit of fluoropyrimidine-based adjuvant chemotherapy for unfit elderly patients? * Second, is there a benefit of oxaliplatin-based adjuvant chemotherapy for fit elderly patients? The aim of this randomized phase III study is to evaluate the benefit for disease-free survival of adjuvant chemotherapy in elderly patient and which chemotherapy. The elderly patient population will be dichotomized into two groups according to physician's choice after a multidisciplinary evaluation involving a geriatrician, with two different randomization assignments. The patients with an expected life-expectancy below 4 years according Lee score are excluded of this study. Some biological tumour abnormalities are more frequently observed in elderly (i.e. mismatch repair deficiency), therefore an evaluation of specific biological prognostic factors is needed in elderly population.

29.3% of bacteremias in intensive care units (ICU) are linked to vascular devices, including 7.7% to arterial catheters, with an influence on both morbility and mortality. It is now accepted that biofilm as a role on bacterial development on inner surface of vascular devices but there is yet a lack of clinical relevant data documenting a causal relation between biofilm formation and bacteremias. The investigators assume that a better structural and microbiological characterization of arterial catheter biofilm in ICU patients could help preventing bacteremias or have a more specific treatment when it appears.
