Anaesthesia and Tryptophan Pathway
Surgery has many immunomodulatory properties of which the mechanism is not clearly understood.
Diagnostic Value of Weight Bearing CT for Detecting Meniscal Tears
This observational study will compare the clinical value of weight-bearing CT arthrography (WBCTa) with that for MRI in evaluating meniscal and cartilage lesions of the knee joint. The MRI Osteoarthritis Knee Score (MOAKS) and modified MOAKS for WBCTa will be used to compare findings between MRI and WBCTa of the …
COVID-19 Associated Lymphopenia Pathogenesis Study in Blood (CALYPSO)
Background COVID-19 is an acute respiratory syndrome. One symptom of COVID-19 is a reduction in the number of cells called lymphocytes in the blood. Lymphocytes are a type of white blood cell that fights infections. With fewer lymphocytes, the body cannot effectively fight back against SARS CoV-2, the virus that …
Layer-specific Contribution to Consolidation of Skill Learning in the Primary Motor Cortex
Background Training in a new motor skill often involves periods of active practice and periods of rest. During early motor skill learning, improvements in performance usually happen during the short rest periods between practice sessions. Researchers want to use improved imaging techniques to study the contributions of specific parts of …
Severe Acute Respiratory Syndrome-Coronavirus-2 and Loss of Autonomy in the Elderly
In most diseases, older people have less typical symptomatology than that described for younger people. The investigators therefore hypothesize that within the framework of coronavirus disease 19, the clinical pictures in the elderly will present specificities that will need to be described. Moreover, since infection by the SARS-CoV-2 virus is …
Factors Influencing the Risk of Surgical Site Infections and Wound Complications in Operatively Treated Ankle Fractures in the Elderly
This study is to analyse risk factors for wound complications or surgical site infections and to analyse whether risk factors for wound complications or surgical site infections are also factors for other complications. Based on the data from this study it will be investigated whether a risk score can be …
Systematic Assessment of SARS-CoV-2 Neurotropic Capacity in Modestly and Critically Ill Patients and Patients Who Died From COVID-19
This study is to analyze the microglia reaction or direct neurotropic effects of CNS COVID-19 in pathogenesis and brain stem dysfunction in critically ill patients. A microglia-focused, brain-specific 50+ marker CODEX panel is used to assess the neuroinflammatory microenvironment in specific brain regions of deceased COVID-19 patients. The peripheral (cerebrospinal …
Daytime Sleepiness in Patients With the Assessment of a Sleep-related Respiratory Disorder
It is not yet known whether an analysis of daytime sleepiness over the course of the day can predict the diagnosis or severity of sleep apnea. The goal of the study is to examine whether a psychometric determination of daytime sleepiness can adequately and practicably record daytime sleepiness in patients …
Imaging SARS-CoV-2 Involvement of Leptomeninges Olfactory and Limbic Areas
When patients arrive in the waiting room of the MRI department, patients will be given the briefing note explaining the purpose of the study and how it is going. During the consultation, the radiologist will check the inclusion and non-inclusion criteria, and will take the time to answer all of …
Quantifying Digital Behavior on Smart Phones - Data From Stroke Survivors
In this study, we want to continuously record the interaction of 50 stroke survivors with their smartphones during the first 3 months after discharge. The linkage of smart phone use to function and quality of life will be assessed with standardized outcome measures at defined time points.
