This is a randomized, double-blinded, placebo-controlled phase 2b clinical trial to characterize, examine and compare the effects of GLP-1 receptor agonist (semaglutide) in HIV-infected adult individuals with lipohypertrophy versus healthy controls with obesity but without HIV.
The two populations will be studied in separate but similarly-designed studies running in parallel.
Subjects in both populations will be assigned by chance (1:1) to semaglutide or placebo.
Scleroderma (systemic sclerosis) is a chronic autoimmune disease, characterized by dysregulation of immune cells in the blood and subsequent fibrosis and vascular dysfunction, associated with significant mortality and morbidity, disproportionately affecting women and African Americans, and without satisfactory treatments. Monocytes, a type of blood immune cells, are critically involved, but the mechanisms responsible for their deregulation in scleroderma remain largely unknown. The goal of this project is to understand how the regulation of monocytes differs between scleroderma and healthy individuals. Volunteers will be asked to provide a blood sample, for which modest compensation will be provided. This is not a drug study.
Outcomes following a breast cancer diagnosis are different by race and ethnicity with African American women having poorer survival compared to Caucasian women. Research has shown that differences in personal health factors can contribute to breast cancer outcomes and explain racial differences. This study will examine how personal-level factors relating to biological, psychological, and physiological issues play a role in outcomes among African American breast cancer survivors.
The purpose of this research study is to understand the association between heart and brain health in a population of 40-75 year olds. In this study, we will work to better understand blood vessel stiffness and brain function in African American and non-Hispanic white individuals. You will be asked to give blood during the study visit. Additional information will be obtained to help the researcher better understand the blood vessel and brain function data collected. There is only one study visit that last roughly 2 hours and compensation will be available.
Delays in starting radiation after surgery for head and neck cancer disproportionately affect minorities and those of low socioeconomic status, causing increased mortality. The barriers that prevent the delivery of timely, equitable postoperative radiation remain unknown. This study seeks to identify the barriers to timely, equitable postoperative radiation following surgery for head and neck cancer.
Older adults typically have trouble identifying the speech they hear, especially in noisy environments. Fortunately, compared to younger adults, older adults are better able to compensate for difficulties identifying the speech they hear by recruiting the visual system. However, the extent to which older adults can benefit from visual input, and how this influence relates to age-related changes in brain structure and function, have not been thoroughly investigated. The general purpose of this study is to determine how age-related changes in brain structure and function affect how well people hear and see. This study seeks participants with normal hearing to mild hearing loss, who also have normal or corrected-to-normal vision.
This research which encompasses a relatively new area of study that uses the Ecological Model to frame investigation is significant because it will help: (a) understand how patient, family, and community level factors impact stroke recovery and account for disparities in post stroke recovery between AA and Whites; (b) engage community members (AA, Health Provider, Families) and (c) integrate this knowledge and the interplay of socio-environmental and behavioral factors so as to develop a multi-level community based intervention with community dwelling AA in the acute post-stroke recovery period. In this model of care, the nurse guides the CHW in evidence-based interventions and the CHW links with community members to deliver the interventions to individuals. It uses nurse teleHealth guidance of the CHW and home based CHW-patient training in self-management. Together they work to disseminate and integrate the successful interventions into health and community systems. These activities will complement and build upon the growing literature related to environment guided lifestyle and self -management programs and will lead to effective socio-culturally tailored stroke recovery interventions that improve long term outcomes by directly addressing factors associated with existing disparities in recovery.
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.
This study if for patients that have a blood disease and it's been determined that the best option for treating that blood disease is a cord blood transplant. Cord blood (CB) is blood that is taken from the umbilical cord and placenta of healthy newborn babies after childbirth. The cord blood collected from a newborn baby is called a cord blood unit. The United States Food and Drug Administration (FDA) considers cord blood to be a biological drug. These are considered "investigational" products. This study will evaluate the safety of administration of the investigational cord blood units by carefully documenting all infusion-related problems.
The primary purposes of this study are to:
?Provide access to cord blood units for recipients whose best choice for a cord blood unit(s) do not meet all FDA standards, but do meet standards set by the NMDP on this study.
?Assess how well and how quickly blood counts return to normal after transplant in recipients on this study.
