ProtocoL for GFR Measurement Using Iohexol (SCOPE-PLUS) - A Substudy of the SCOPE Study
Chronic Kidney DiseasesSCOPE-PLUS is an optional substudy of the observational SCOPE Study (Screening for Chronic Kidney Disease among Older People across Europe, NCT02691546). The objective of the SCOPE-PLUS study is to derive new equations based on innovative and novel biomarkers of CKD function and compare its accuracy to measure GFR in the population older than 75 years.
Renal MR Feasibility in Renal Disease
Renal DiseaseTo use Non-invasive MR Imaging of Renal Physiology and structure to assess patients with Acute Kidney Injury (AKI) and Chronic Kidney Disease (CKD).
Prediction of Expected Length of Hospital Stay Using Machine Learning
InfectionHeart Failure7 moreThis is a retrospective observational study drawing on data from the Brigham and Women's Home Hospital database. Sociodemographic and clinic data from a training cohort were used to train a machine learning algorithm to predict length of stay throughout a patient's admission. This algorithm was then validated in a validation cohort.
MRI Biomarkers in Diabetic Kidney Disease
Diabetic NephropathiesDiabetic kidney disease is one of the most severe and frequent complications of diabetes. Few preclinical markers are available apart from plasma creatinine and microalbuminuria. These markers are imperfect (some patients with advanced renal disease do not have an increase in markers) and late. Therefor there is an uncovered need to identify complementary biomarkers. Magnetic Resonance Spectroscopy (MRS) is a Magnetic Resonance Imaging (MRI) technique that allows the physiology and biochemistry of human body tissues to be studied in a non-invasive and non-irradiating manner.
A Study of Wrist Worn Accelerometers in End-Stage Renal Disease
Chronic Kidney DiseasesEnd Stage Renal Disease on Dialysis1 moreThe kidneys are important at getting rid of toxins and excess water from the body. If they fail, then toxins and excess water builds up within the body. Kidney failure is treated by either giving patients a new kidney (a transplant) or by removing the toxins and fluid from the body by the process of dialysis. The investigators' aim is to personalise the care given to patients with kidney failure, and as such, they have started measuring the fitness of patients with kidney failure, who either already require dialysis or may need dialysis in the near future. This is currently done in a number of ways including measuring how strong their grip is, assessing their walking speed and asking questions about how difficult they find certain activities. In the future, the investigators think that this will allow targeted treatments to help improve their fitness and potentially identify any problems earlier. Current approaches to measuring activity and fitness have limitations and in particular may over- or underestimate the level of the physical activity. To over come these limitations, participants will be asked to wear an activity tracker (called an accelerometer) on for a week. Readings from the accelerometer will be compared against the other markers of fitness and activity to see if they are comparable. It will also be noted whether patients are prepared to wear the device for 7 days (compliance).
Investigation of Relationship Between Contrast Nephropathy and Caval Index Measurement in Patients...
Ileus; MechanicalContrast-induced NephropathyIn this study, the investigators aimed to evaluate the incidence of vena cava inferior diamater on ultrasound guidance of intravascular volume before diagnosis of contrast - enhanced CT for diagnostic purposes in ileus patients and to investigate the incidence and risk of developing contrast nephropathy due to contrast - enhanced CT.

Metabolic Changes in Patients With Chronic Cardiopulmonary Disease
Heart FailureChronic Obstructive Pulmonary Disease2 moreThis study aims to evaluate prevalence of sarcopenia and cachexia in patients with chronic cardiopulmonary disease. The investigators will also investigate metabolic disorders like glucose metabolism, presence of metabolic syndrome, body composition and histological changes in skeletal muscle and body fat. Finally, patients will be followed for clinical endpoints.
Duration of Protection From Pneumonia After Pneumococcal Vaccination in Hemodialysis Patients
CKD (Chronic Kidney Disease) Stage 5DPneumoniaThe investigators compare two strata of vaccinated patients: those recently vaccinated and those vaccinated more than two years ago. The primary objective is to compare pneumonia rates between the groups. As exploratory objectives, the investigators will describe the anti-pneumococcal antibody titers in hemodialysis patients as a function of time since vaccination, and determine factors influencing antibody kinetics. Further exploratory objectives investigate the relationship between antibody titers and the incidence of pneumonia in hemodialysis patients and extrapolate a possible cut-off for protection from pneumonia.
Parathyroid Hyperplasia in Patients With Chronic Kidney Disease.
Chronic Kidney DiseasesSecondary hyperparathyroidism is an important complication in patient with chronic kidney disease . It is associated with bone complication and an increase in cardiovascular mortality The parathyroid hormone rises in these patients as consequence of low concentration of vitamin D3 ,reduction in quantities of serum calcium, phosphorus retention and reduction of vitamin D receptors sensitive to calcium.
