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.
1. Cell-free DNA does not vary significantly as a function of the activity of immunologically quiescent cardiac transplant recipients, despite the metabolic demands of the transplanted organ. (The implication of the null result would be that no restrictions to patient activity, nor modification of cardiac rehabilitation prescription, would be necessary to maintain proper test characteristics of AlloSure testing). 2. In immunologically active cardiac transplant allografts, exercise prior to assay of donor-derived cell-free DNA can be used to increase the sensitivity of the AlloSure test. (The implication of this would be that the optimal time-frame for drawing an Allosure may actually be post-exercise, and that window will be characterized).
AlloSure Test Characteristics in Immunologically Quiescent and Immunologically Active Heart Transplant Recipients: Does Maximal Cardiopulmonary Stress Testing Prior to Assay Preserve Test Specificity While Enhancing Sensitivity?
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.
