Candidates for this study may or may not report disturbances in odor perception as their primary reason for seeking treatment at MUSC. This study is designed to collect long term, observational data from patients who are being treated with routine clinical care in health clinics at MUSC. Data from clinical questionnaires will be de-identified and stored in a database.

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.

The purpose of this study is to determine if environmental toxin exposure differs in African American women as compared to White women with endometrial cancer and to evaluate the relationship between demographic variables and toxin level.

Systemic lupus erythematosus (lupus; SLE) and Systemic Sclerosis (scleroderma; SSc) are relatively rare rheumatic diseases that disproportionately impact the African American community, and particularly African American women. The causes of lupus and scleroderma are unknown, but thought to include both genetic and environmental factors. We are enrolling lupus and scleroderma patients, and healthy control subjects. This is not a drug study. The purpose of this study is to better understand the factors that predispose people to develop lupus and scleroderma. Information about medical, social and family history, medications, physical exam findings, and laboratory tests will be collected for analysis. This study will involve approximately 1360 volunteers.
