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.
Gastrointestinal (GI) dysfunction affects up to 50% of medical and surgical critically ill children. GI dysfunction, specifically gastric dysmotility and loss of epithelial barrier integrity, is associated with significant morbidity in critical illness. The mechanisms underlying GI dysfunction in critical illness are not well understood. GI dysfunction in surgery and critical illness has been associated with inflammation. There is evidence to suggest the protease-activated receptor 2 (PAR2) is a link between inflammation and GI dysfunction. PAR2 is a G-coupled receptor present throughout the GI tract. PAR2 mediates GI motility and epithelial barrier integrity. PAR2 is activated by PAR2 agonists, specifically GI serine proteases and zonulin, released under conditions of inflammation. In this study the investigators will examine the relationship between inflammation and PAR2 activation by PAR2 agonists and subsequent GI dysfunction in pediatric critically ill surgical patients. The overall hypothesis of this study is that PAR2 activation by PAR2 agonists, GI serine proteases and zonulin, released due to inflammation results in gastric dysmotility and loss of epithelial barrier integrity. In this study, the investigators will examine whether PAR2 agonist expression is increased and correlates with GI dysfunction in critically ill surgical pediatric patients. This proposal fills a knowledge gap in the understanding of mechanisms for GI dysfunction in critical illness, and will be applicable to all surgical and medical critically ill children.
Examining the Role of Protease-activated Receptor 2 Agonists in Gastrointestinal Dysfunction in Pediatric Surgical Critical Illness
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.
