BioEXALK is a prospective study evaluating the biological characteristics of advanced ALK-rearranged NSCLC treated with new generation TKIs in first line, included in the national EXPLORE ALK cohort (GFPC 03-2019). Explore ALK GFPC 03-2019 is a non-interventional, national, multi-center cohort of ALK-rearranged NSCLC patients, whose RCB reference is 2020-A00771-38 and which obtained an approval from the IDF II Ethic Committee on 25/05/2020. Biological analysis will be performed on tissue at diagnosis and at the time of disease progression when available and on circulating tumor DNA (ctDNA) on three timepoints (diagnosis, at first tumor evaluation and at the time of disease progression). * Tissue : RNAseq will be performed on tumor biopsy (10 slides of 5 microns) to identify the ALK fusion partner and its variant and associated co-mutations.. * ctDNA : NGS panel on DNA including a large panel of fusions and mutations will be performed on blood samples (30mL on EDTA or STRECKs tubes) at diagnosis, at the time of the first evaluation and at the time of progression). For plasma testing, after obtained patient consent, blood samples (35mL on EDTA or STRECKs tubes) at diagnosis, at the first evaluation and at disease progression will be taken. The ALKis include alectinib and brigatinib as first-line therapy or other drugs with marketing authorizations (lorlatinib, entrectinib) or in early access programs (EAPs). Liquid biopsies will be analyzed with a NGS panel allowing the identification of ALK fusion partners and resistance mechanisms (mutations, fusions, copy number variations). Samples will be sent for centralized analysis to the Léon Bérard Center (Lyon). For biological analysis on tissue obtained at diagnosis, the ALK fusion partner and its variant will be identified by RNAseq. Whenever a tissue re-biopsy is performed at the time of disease progression as part of the standard of care management of the patient, the remaining tissue sample will be collected as part of the BioExALK study, so that RNAseq analysis will be performed to look for resistance mechanisms. Tissue samples (10 slides of 5 microns) will be sent for centralized analysis to the Rouen University Hospital.

The study proposes to test an intervention consisting of dual long-acting HIV-specific broadly neutralizing antibodies (3BNC117-LS \& 10-1074-LS ) + ART, at primary HIV-1 infection, and to compare it to ART only regarding HIV-1 replication. The study aims to enrol 69 participants in French (Ile-de-France) clinical centres. Participants will have been diagnosed with primary HIV-1 infection, will start ART during early phase of Primary HIV infection, and will interrupt ART 52 weeks later. Study duration will vary by participant, depending on the time of ART interruption and the time to viral rebound.

The Dataids cohort is a prospective observational cohort of 30,000+ patients followed in 15+ HIV centers scattered throughout France. The Dataids cohort is an ongoing collaboration and patients have been enrolled into the study since 2010; the data are collected from the clinics as part of routine care. Included patients should be patients who had a scheduled visit in the outpatient clinic regardless of CD4 cell count, HIV viral load or ART status. For all HIV patients enrolled and under follow up, demographic data, immunological and virological data, serological evidence for infection with hepatitis B virus (HBV), hepatitis C virus (HCV), or syphilis, laboratory, therapeutic and clinical data are collected annually.

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.

There is a great heterogeneity in the practice of rapid sequence induction in the operating room in the world. There are no recent data assessing the rate of implementation of the latest French formalized expert recommendations in clinical practice. In addition, the modalities for the management of haemodynamic disorders, particularly hypotensive disorders, during rapid sequence induction are not described in these recommendations, although these are frequent events with a non-zero morbidity mortality potential. The goal of this prospective, observational, multicenter, anesthetic study is to describe the clinical practice of French anesthesiologists regarding the prevention of severe hemodynamic disorders during rapid sequence anesthetic induction in adult patients. The primary outcome measure is the occurrence of a major haemodynamic disorder defined by a MBP ≤ 50 mmHg (or ≤ 40% of the reference value) and/or ≥ 110 mmHg and/or the occurrence of sustained arrhythmia not present at induction and/or cardiac arrest within the first 10 minutes after induction of anesthesia. The clinical practices of pre-oxygenation, induction and intubation of French anesthesiologists and compliance with the formalized expert recommendations of 2017 and 2018 will also be studied secondarily. The elements for the prevention of gastric fluid inhalation, the organization and equipment used, the anesthetic and non-anesthetic drugs used, the clinical and paraclinical neurological and cardio-respiratory parameters and the nature of the complications following anaesthetic induction will be collected up to the 10th post-induction minute.

The emergence of extended-spectrum beta-lactamase-producing Enterobacteriaceae (E-ESBL) is a major public health problem. It leads more frequent prescription of penems with the risk of emergence and spread of strains producing carbapenemases, which may be resistant to all known antibiotics. A policy of savings of penems is desirable. Among the alternatives to penems, amikacin is in the foreground. It remains active on the majority of E-ESBL strains. Some risk factors for E-ESBL emergence are known: recent antibiotic therapy (particularly quinolones and cephalosporins third generation), previous hospitalization or residence in a high endemic country. In pediatrics, E-ESBLs are primarily responsible for urinary tract infection. In France, E-ESBLs represent about 10% of the strains responsible for urinary tract infections. The Pathology Group Pediatric Infectious (GPIP) of the French Society of Pediatrics (SFP) and the Society of Infectious Pathology French Language (SPILF) have proposed different therapeutic options to treat febrile UTIs in children: amikacin intravenous; intravenous (IV) ceftriaxone or intramuscular (IM); or cefixime per-os (PO). The objective of this study is to compare the emergence of E-ESBLs in stools of children after febrile UTIs treatment with amikacin IV versus ceftriaxone or cefixime.

Very few data has been published on the epidemiology of hypoparathyroidism worldwide. None exists specifically in France. Hypoparathyroidism could led to complications: e.g. symptomatic hypocalcemia, calcifications (brain, eye and other soft tissues), nephrolithiasis/nephrocalcinosis, renal insufficiency. Here,the investigators plan to collect data about both epidemiology, medication and complication of hypoparathyroidism in France.
