Tissue Collection and Characterization: Longitudinal Senescence Analysis
The purpose of this study is to better understand the makeup and composition of blood and fat tissue in people with a variety of health conditions. We are specifically interested in identifying and characterizing a specialized state of cells called senescence. This is when cells in our body stop dividing, but still produce inflammatory signals in the body. Senescent cells have been linked to a variety of metabolic diseases related to inflammation. We are collecting fat tissue and blood samples to look for genes that are associated with inflammation and senescence. These samples will be collected from healthy people as well as people with different metabolic diseases, who are already undergoing ENT surgery as part of their care at the University of Minnesota, to find meaningful patterns that can help lead to better treatments.

A novel partial-enteral nutrition protocol to improve nutrition status of adult patients experiencing a Crohn's disease flare and starting new immunologic therapy
The purpose of this study is to evaluate if a partial enteral nutrition diet, with a pea protein plant-based oral nutrition supplement (ONS; Kate Farms Peptide 1.5), combined with the Inflammatory bowel disease - Anti-Inflammatory Diet (IBD-AID) improves the nutritional intake of adult patients experiencing a CD flare initiating immunologic therapy compared to standard of care. Standard of care for patients experiencing a CD flare is commonly characterized by prescription of a low fiber diet and either lack of oral nutrition supplementation or use of an animal protein based supplement.
