This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
There is need for a whole blood analog for use when banked blood is unavailable or undesirable. In civilian trauma, hemorrhage accounts for \~ 35% of pre-hospital deaths; moreover, \~ 20% of military casualties are in hemorrhagic shock on arrival to field hospitals and an additional 5% require urgent transfusion. A recent review concluded that hemorrhage accounted for \~ 90% of potentially survivable battlefield deaths - lives that could be saved with better hemorrhage control capabilities and improved, field-ready blood, blood components, or blood substitutes. While study of ideal composition for resuscitative fluids is ongoing, it is evident that for those in hemorrhagic shock, volume replenishment alone (without O2 carrying capacity) is insufficient. Alternatively, with massive blood loss or with ongoing bleeding from non-compressible injuries, resuscitation with an O2 carrier alone may be complicated by acquired coagulopathy (either dilutional or trauma-induced). Development of a balanced resuscitation fluid that treats both shock and coagulopathy (comprising a field-deployable O2 carrier with lyophilized humoral hemostatic components and platelets) is essential to allow on-scene treatment during the critical 'golden-hours' after injury. As such, the whole blood analog described herein could be this product, thus transforming care in both civilian and military settings.The scientific purpose of this study is to develop a combined whole blood substitute from individual artificial prototypes that have been separately developed for each blood component (i.e., combining an artificial oxygen carrier, with an artificial plasma analogue and an artificial platelet analogue). Together, these combined components will recapitulate the composition and performance of natural whole blood. Blending and combination experiments of the individual artificial prototypes will be performed to test compatibility and optimize efficacy. State of the art in vitro (bench top) assays will be performed to assess physicochemical and functional performance (hemodynamics, oxygen delivery, hemostasis), with data being compared to experiments performed on fresh and stored whole blood.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
