Children spend more time than ever using screens — increasingly on portable digital media devices like tablets and smartphones, but our understanding about how these devices impact health is lagging. This project proposes to uncover how patterns of digital media use are formed and maintained and examine how those patterns predict mental health and cardiovascular health risk over time. The novel forms of media measurement used in this project – including passive mobile sampling, ecological momentary assessment and accelerometry – will allow us to uncover the unique and complex ways in which digital media impacts health behaviors.

Adult and Pediatric patients with glomerular disease:
Patients of all ages are needed to participate in a research study to investigate glomerular disease and create a worldwide database to help in the research and future treatment of this disease. To join this study, you must have a type of glomerular disease, have had a first kidney biopsy within the last 5 years, not be on dialysis, or not have had a kidney transplant.

The study is projected to last 4 years, and all study procedures will be done at regular clinic visits (between 1 and 3 yearly). Study procedures include filling out questionnaires and a blood draw at each visit.

Compensation is available for study participation.

Heart disease can be detected in the hospital by Cardiac Magnetic Resonance (CMR)- a device that uses a large magnet. CMR is used to test how healthy the heart muscle is and how well the heart is pumping. We will test a new method to see how helpful it is to quickly get good pictures and if this is useful for testing the health of heart muscle in patients with heart disease.
