NCT06704126
This study aims to examine the blood sugar response after a meal, and how three different movement protocols may impact the blood sugar level. Participants will visit the lab on three different occasions. Before each visit the participant will eat a meal we give them and have a cannula (a needle with a tube) put in their arm to allow blood sampling for the visit. Visit A will be the participant just having their legs moved by the machine, visit B will be the participant having their legs moved by the machine with the addition of blood pressure cuffs on their thighs, and visit C will just be the participant sitting still on the machine.
NCT07112898
This clinical study aims to evaluate whether applying platelet-rich plasma (PRP), a substance made from a person's own blood, can improve the success of full-thickness skin grafts used to treat facial and neck wounds. Skin grafting is a common reconstructive technique for covering wounds caused by injuries, burns, surgeries, or other conditions. However, skin grafts sometimes do not heal well, leading to complications such as graft failure, infection, or delayed healing, especially in delicate areas like the face and neck. Platelet-rich plasma contains special healing components called growth factors that may help tissues heal faster and better. These growth factors support new blood vessel formation, reduce swelling, and promote healthy skin regeneration. In this study, participants will be randomly assigned to one of two groups. One group will receive skin grafts along with PRP applied to the wound and graft site, while the other group will receive standard grafting without PRP. The study will measure how much of the graft survives and integrates into the wound (called "graft uptake") on the 7th day after surgery. It will also assess other early outcomes such as signs of redness (erythema), infection, or blood collection under the graft (hematoma). The hypothesis is that using PRP will lead to better graft healing and fewer complications than using skin grafts alone. The results of this study may help improve recovery and reduce the need for further procedures in patients with facial and neck skin defects.
