Treatment Group
Will have a Unit of blood (two cups, the same amount donated at the Red Cross) drawn. This involves having a needle inserted into a vein in your arm. Prior to taking the blood, staff will measure your blood count to be sure you are not anemic, and blood pressure to be sure no dehydration. During or after donation, a sports drink is provided to replace the fluid loss. Phlebotomy Blood Donation: Participants in the TREATMENT GROUP will have a Unit of blood (two cups, the same amount you would donate at the Red Cross) drawn. This involves having a needle inserted into a vein in your arm. Prior to taking the blood, staff will measure blood count to be sure participants are not anemic, and blood pressure to be sure there is no dehydration. During or after donation, participants will be given a sports drink to replace the fluid loss. Participants in the CONTROL GROUP will not donate blood, but will have a needle inserted into a vein in your arm. Neither group will not know to which they have been assigned, all will have a sleep mask (like a blindfold, covering the eyes, held on with an elastic band) placed so they will not know whether blood was actually removed.
Control Group
Will not donate blood, but will have a needle inserted into a vein in your arm. Both groups will not know which group assignment they have been randomized. Sham Phlebotomy Sham Blood Donation: Participants will have a needle inserted their arm, however, no blood will be drawn.

Timeframe: Baseline

Population: Only a few participants were able to donate for this outcome because the lab closed due to COVID--it was not collected at the same visit as all other baseline labs.

Studies often report DI values with a wide range. Normal or reference ranges can vary substantially depending on the study. Higher values indicate better -cell function. The Disposition Index (DI) derived from the Frequently Sampled Intravenous Glucose Tolerance Test (FSIGTT) is a measure of pancreatic -cell function, calculated as the product of insulin sensitivity (S1) and the acute insulin response to glucose (AIRg). It acts as a marker for how well insulin secretion compensates for insulin.

SECONDARY outcome

Timeframe: baseline, month 12

Population: Not collected in all participants

Insulin sensitivity measured by HOMA-IR (Homeostatic Model Assessment-Insulin Resistance) calculated from fasting glucose and insulin. Values will be reported for Baseline and 12 months. HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) is a calculated score that uses fasting insulin and glucose to measure insulin resistance. An optimal score is generally below 1.0, while values above 1.9 suggest early insulin resistance, and those above 2.9 indicate significant insulin resistance. HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) measures insulin resistance by multiplying fasting insulin and fasting glucose, then dividing by 405. A score below 1.0 indicates optimal insulin sensitivity, while above 1.9-2.0 suggests early resistance, and above 2.9 indicates significant resistance.

Treatment Group
n=19 Participants
Will have a Unit of blood (two cups, the same amount donated at the Red Cross) drawn. This involves having a needle inserted into a vein in your arm. Prior to taking the blood, staff will measure your blood count to be sure you are not anemic, and blood pressure to be sure no dehydration. During or after donation, a sports drink is provided to replace the fluid loss. Phlebotomy Blood Donation: Participants in the TREATMENT GROUP will have a Unit of blood (two cups, the same amount you would donate at the Red Cross) drawn. This involves having a needle inserted into a vein in your arm. Prior to taking the blood, staff will measure blood count to be sure participants are not anemic, and blood pressure to be sure there is no dehydration. During or after donation, participants will be given a sports drink to replace the fluid loss. Participants in the CONTROL GROUP will not donate blood, but will have a needle inserted into a vein in your arm. Neither group will not know to which they have been assigned, all will have a sleep mask (like a blindfold, covering the eyes, held on with an elastic band) placed so they will not know whether blood was actually removed.
