Project 1: Physical Activity and Sedentary Behavior in Chronic Kidney Disease

This project aims to describe and quantify the prevalence, risk factors, and consequences of sedentarism in patients with chronic kidney disease.

Project 2: Patient-Reported Symptoms in Chronic Kidney Disease

The goals of this project are to 1) develop a practical chronic kidney disease symptom measurement tool with high construct validity and 2) identify circulating metabolites and retained uremic toxins that predict the degree of specific symptoms in CKD.

Project 3: Mineral Metabolism Disturbances, Race, and Cardiovascular Outcomes

Within this project, we are evaluating associations of mineral metabolism markers (e.g., parathyroid hormone, 24,25-dihydroxyvitamin D, fibroblast growth factor-23) with cardiovascular events in a large, community-based, multi-ethnic population of adults free of clinical cardiovascular disease at baseline. In particular, we are examining whether these associations vary by race.

Project 4: Genetic Variation and Mineral Metabolism Disturbances

The genetic underpinnings of the regulation of mineral metabolism markers (e.g., parathyroid hormone, 24,25-dihydroxyvitamin D, fibroblast growth factor-23) remain poorly understood. We are currently conducting several large genome wide association studies to investigate associations of common genetic variants with serum concentrations of these markers.
