148 Background and Aims: The indirect pathway of allorecognition is characterized by recipient alloreactive T cells recognizing donor peptide antigen presented MHC Class II molecules on APC's. Evidence accruing that chronic rejection (CR) may be mediated primarily the allorecognition. We compared response in heart (low risk for early CR) lung (high allografts during quiescence (i.e. no evidence acute or rejection). Methods: Limiting dilution analysis (LDA) was performed to quantify frequency...

e18857 Background: Adolescent Young Adults (AYAs) are likely to live for decades after a cancer diagnosis and thus have the potential accumulate high healthcare costs. Prior research has shown costs can be associated with increased risk of morbidity mortality. However, there is limited understanding how impact AYAs, especially in community hospital. The purpose this study 1) understand total hospital AYA patients cancer, 2) identify factors costs, 3) assess on survival. Methods: (ages 15-29)...
