This clinical research study is enrolling adults with diabetes, prediabetes or metabolic syndrome. The purpose of the study is to learn more about preventing cardiovascular disease. A heart CT scan will be done at screening and then 2 years later. Qualified participants will be randomly assigned to one of two groups. Participants in the usual care group, will continue to receive care from usual health care provider. In the personalized care group, participants will receive additional health care from a remote cardiologist led team which will individualize treatment based on Cleerly CAD staging results of the heart CT scan. Study is expected to last 3 1/2 years on average but could be 2 - 5 years. Participation is free.

The COVID and Diabetes Assessment (CODA) study is for adults who have been diagnosed with type 1 diabetes or type 2 diabetes within the last 90 days. This study will examine if having a recent COVID-19 infection may impact the course of diabetes. We will gather information about both diabetes and COVID-19 infection. Participants will be followed for 2 years and asked to complete surveys and provide blood samples. No treatment or medications are involved in the study.

This study includes a longitudinal mixed methods study of 360 YYA with diabetes in SC, CO, and WA conducted with SFS 1 participants. SFS 2 will have two parts: (1) an intense, longitudinal study consisting of two 14-day assessment periods spaced 9 months apart which will include CGM, EMA, accelerometry, and surveys in all participants (the EMA study); and (2) a concurrent events qualitative study with a subset of participants (30 T1D, 15 T2D) who will complete 13 one-on-one, semi-structured interviews throughout the 9-month assessment period (the qualitative study).

This study will involve taking one or two medications already approved by the Food and Drug Administration (FDA) for treatment of type 2 diabetes to learn more about which diabetes medications are the best for lowering the risk of heart and kidney disease in individuals with type 2 diabetes who are at least 40 years old. Participation includes about 8 study visits over a period of 72 months, which can be performed over the phone remotely or during normal standard of care clinic visits. Participants will be compensated for their time and participation in this research study.

The purpose of this study is to obtain long-term diabetes control information after patients' participation in the MSC in T1D trial. Specifically, the goal of this study is to determine if patients receiving an MSC infusion in addition to the standard of care for diabetes have a long-term beneficial effect in slowing disease progression than patients receiving placebo infusion.

Islet transplantation is a clinical procedure to treat patients with chronic pancreatitis after removal of their pancreases. Islet survival is influenced by several factors, including but not limited to triggering an inflammatory response. The loss of islet cells during transplantation can cause surgical diabetes, in which the patient will need insulin injections to regulate their blood sugar. The goal of this study is to test whether co-transplantation of the patient's stem cells, called mesenchymal stromal cells (MSCs), along with their islet cells, will protect transplanted islet cells from death, therefore reducing the patient's chances of getting surgical diabetes. MSCs can modulate immune cells and are a promising resource for cell-based therapy.
