CoV-ICU Score, Intensive Care Unit, SARS-CoV-2
Coronavirus as the Cause of Diseases Classified ElsewhereIn the course of COVID disease, some patients need intensive care treatment. We aim to find an answer to the question of whether the patient's CRP, ferritin, D-dimer, Oxygen Saturation, lymphocyte count, and body mass index can be used as a criterion for admitting patients with COVID to the intensive see unit.

Defining the Operating Parameters for a Rebound-esthesiometer
Corneal Sensation ReducedCorneal Dystrophy3 moreThe purpose of this study is to define the operating parameters for a new method to measure corneal sensitivity.

Developement and Evaluation of Serological Assays for COVID-19
COVID-19The primary objective of the study aims to evaluate serological assays of virus Covid-19.

Serological Testing for COVID-19 (SARS-CoV-2) in ESKD
SARS-CoV 2End Stage Renal Failure on DialysisStarting in late 2019, the world is facing a pandemic with the SARS-CoV-2 virus. Patients with end-stage kidney disease and on treatment with renal replacement therapy are high risk patients, as they are unable to maximize social distancing. We plan to gather epidemiological data using two different diagnostic approaches. We will compare a symptom-driven screening, in combination with a nasopharyngeal swab plus computed tomography (clinical approach) against serological surveillance.

COVID 19 Seroprevalence Amongst Healthcare Workers in JHAH
COVID 19Healthcare workers play a critical role in fighting the pandemic, not only by managing the patients' health clinically, but also by implementing adequate measures for infection prevention and control in healthcare facilities. This puts healthcare workers at a greater risk of acquiring the disease. COVID-19 is caused by Severe Acute Respiratory Syndrome Coronavirus -2 (SARS-CoV-2) and many people can be infected with it asymptomatically and undetectably. Serology is an antibody test that provides additional information to polymerase chain-reaction (PCR) testing as it is the only way to reliably establish the fraction of the population that was infected . Seroconversion is the development of antibodies in the blood which can confirm suspected cases after the fact and reveal who was infected but asymptomatic and never realized it. Antibodies are specific proteins created as the body's response to the infection and this test is essential for detecting infected individuals with few or no symptoms at all.

Acute Kidney Injury and Renal Outcomes for COVID-19 Patients in Intensive Care Units
on Occurrence of Acurate Kidney Injury During Intensive Care UnitAbnormalities of Urinary AnalysisThe actual COVID-19 epidemy is an unprecedented healthcare problem. Although acute respiratory distress syndrome is the main organ failure, acute kidney injury (AKI) has appeared to be more frequent and more severe than expected. Some data suggested a potential direct renal tropism of the virus, or undirect injury by "cytokine storm". The aims of this study are: To describe incidence, severity and mortality associated with AKI during covid-19 infection in ICU To identify specific risk factors for AKI To explore pathophysiologic mechanism of AKI during COVID-19 infection

LILLE COVID RESEARCH NETWORK (Covid-19)
Sars-CoV2The Lille University Hospital developped a research objective common to all the services which took care of patients, "suspected patient", "possible case", "probable case" or "confirmed case" infected with SARS-CoV-2 by constituting a prospective and a retrospective observational cohort which allowed pooling and sharing the resources and data collected. In the next two years the prospective cohort will allow to continue inclusions in a standardized way mainly for the constitution of a negative control group (excluded cases), to collect biological samples which had not been collected in the retrospective cohort so that the pathophysiology of the COVID-19 will be better apprehended as for example the inflammatory response to the viral infection. Finally in case of a second epidemic wave in the Hauts De France, it seems essential to have a defined research protocol which had already received all the necessary authorizations to guarantee cutting-edge (or quality ) research in a center like the Lille University Hospital.The aim objective of this study is to identify predictive factors of mortality to day 28 infection to SARS-CoV-2 for patients under medical care for the COVID-19 in the Lille University Hospital thanks to the constitution of an epidemiological, clinical, biological, immunological, genetic, microbiological, anatomopathologic, radiological, therapeutic database and so record the results of functional exploration exams.

Performance Testing in Young Soccer Players
Physical PerformanceThe aim of this study is to investigate physiological characteristics, body composition and performance indicators among youth soccer players of four age categories (U-12, U-14, U-16, and U-18). Participants will undergo assessment of their body weight, body height and percent of body fat as well as performance testing including flexibility, strength, vertical jump, speed, repeated sprint ability, agility, dribbling and endurance.

Variation in Body Composition on the Fate of Older Subjects During SSR Hospitalization
Body Weight ChangesThe aim of this study is to correlate weight variation as well as body composition with mortality and unscheduled readmission of geriatric population

Biomechanical Mechanism of the Change of the Gait Touch Information After ACL Rupture
Anterior Cruciate Ligament InjuriesHigh incidence rate of knee osteoarthritis and gait analysis are important for early assessment of biomechanics. ACL injury is an ideal clinical model for studying knee osteoarthritis. To clarify the mechanism between the biomechanical status of knee joint and the change of gait touch information, and to provide scientific basis for quantifying and evaluating the biomechanical status of knee joint in dynamic load-bearing state.
