Obesity, Metabolic Dysregulation and the Airway Epithelium in Asthmatics

Study Overview

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.

Description

The objective of this pilot study is to determine whether obesity and metabolic syndrome are in fact synergistic in relation to airway nitric oxide (NO) biology. To do so, the investigators want to determine how obesity and the metabolic syndrome relate to metabolism in bronchial airway epithelial cells and the nasal epithelium.
