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.

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.

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).

Assessment of Blood Pressure Control and Target Organ Damage in Patients With Chronic Kidney Disease...
Chronic Kidney DiseaseHypertensionThe purpose of this study is to find the change of blood pressure (BP) control pattern (true controlled, white-coat, masked, and sustained uncontrolled/ dipper, non-dipper, reverse-dipper, and extreme-dipper) in patients with chronic kidney disease (CKD) over 3 years. And Other objective is the relationship between the BP control pattern and the target organ damages such as renal function, proteinuria, left ventricular hypertrophy (LVH), and so on. In addition, we will find clinical factors related to the BP control pattern.

KoreaN Cohort Study for Outcome in Pediatric Patients With Chronic Kidney Disease
Chronic Kidney Disease(CKD)KNOW-CKD (KoreaN cohort study for Outcome in patients With Chronic Kidney Disease) is a nation-wide, ten-year longitudinal cohort study, launched in 2011. The aim of the study is to assess the characteristics and risk factors of progression and complications of CKD of Korea. Pediatric sub-cohort of KNOW-CKD is planned to enroll 450 children with CKD, stage I to V (pre-dialysis).

Comparison of Outcomes Between Hemodialysis and Peritoneal Dialysis Patients in a Multi-Ethnic Asian...
Stage 5 Chronic Kidney DiseaseHemodialysis1 moreEnd-stage renal disease (ESRD) presents a heavy burden on a patient's psychological and social life, as well as overall quality of life (QoL). Health-related quality of life (HRQoL) in dialysis patients measures the physical, social or emotional well-being that is affected by ESRD and/or its treatment, and has been increasingly used as an outcome measure in interventional studies. Additionally, associations between social support and QoL have been observed, indicating that improved social support could improve HRQoL, morbidity and mortality in ESRD patients. However, it is not clear if hemodialysis (HD) and peritoneal dialysis (PD) have different impacts on HRQoL. Furthermore, comparisons of HRQoL and social support between HD and PD patients in the multiethnic society of Singapore have not been evaluated. As such, the investigators propose to conduct this cross-sectional study in the investigators local multiethnic ESRD patient population to evaluate and compare patient-reported outcomes (HRQoL and social support), economic and clinical laboratory outcomes in HD and PD patients. All chronic HD and PD patients seen in NUH outpatient renal or PD clinic will be included in this cross-sectional, observational study. Information on patient demographics, medical/medication histories, dialysis vintage, clinical laboratory data and associated medical costs will be obtained from clinic notes, electronic medical records and hospital databases. Patient-reported outcomes will be determined from scores of the Kidney Disease Quality of Life-Short Form, EuroQol 5 Dimensions, Family Functioning Measure, Oslo-3 Social Support Scale, Multidimensional Scale of Perceived Social Support, Kessler Psychological Distress Scale and Health Services Utilization questionnaires (for indirect costs), and compared between HD and PD patients. Results from this study will provide important HRQoL information to assist renal physicians and patients to make treatment decisions. Furthermore, intervention programs could be developed to improve social support based on patients' needs. These could in turn improve patients' HRQoL, morbidity and mortality outcomes with minimal risks involved.

Utility of Brain Natriuretic Peptide (BNP) in Patients With Type IV Cardio-renal Syndrome Admitted...
Chronic Kidney DiseaseAcute Heart FailureAdmission BNP was a useful marker for diagnosing and predicting type IV cardio-renal syndrome type IV in patients with chronic kidney disease admitted to the ICU for acute heart failure in a retrospective study. Therefore, we aim to prospectively investigate the utility of serum BNP in evaluating the treatment adequacy and predicting future cardiac events in patients with type IV CRS.
