Many youth and young adults (YYAs) with type 1 diabetes (T1D) and type 2 diabetes (T2D), particularly those of minority race/ethnicity, do not achieve optimal glycemic control and household food insecurity (HFI) may be a key barrier. HFI is the limited or uncertain availability of nutritionally adequate and safe foods. The SEARCH Food Security (SFS) cohort study is designed as an ancillary study to the ongoing NIH/NIDDK-funded SEARCH for Diabetes in Youth 4 Cohort study. The aims of the SFS study are to (1) Initiate a food insecurity cohort study of 1,187 YYAs aged 15-35 years (53% minority) with T1D and T2D by adding two data collection time points to the ongoing SEARCH 4 study in three of the five SEARCH sites, including South Carolina, Colorado and Washington; (2) Evaluate how HFI influences changes in glycemic control in YYAs with T1D and T2D; (3) Identify the pathways through which food insecurity may act; and (4) Evaluate the influence of HFI on changes in health care utilization and medical and non-medical health care costs in YYAs with T1D and T2D.
Kidney failure occurring after heart failure is a serious problem leading to prolonged ICU stay, prolonged hospitalization, dialysis and death. The goal of this study is to identify patients who will develop severe kidney failure after heart surgery. Early identification of patients who will develop kidney failure after surgery will allow earlier and better treatment to prevent this complication. In this study, urine is collected after surgery and analyzed to determine the concentration of many proteins. These proteins are potential biomarkers to predict the development of kidney failure. This is a multi-center study funded by the National Institutes of Health. It is being performed at Duke University, George Washington University and the University of Tennessee. MUSC is the lead center.
