A Prospective, Non-Randomized, Multi-Center Observational Study to Establish a Physical Baseline Profile for Individual Study Subjects Using Various Modalities and Identify Deviations Via Longitudinal Monitoring That May Develop Over Time

The two key elements of the PUER Research protocol include (1) molecular and laboratory profiling and (2) non-invasive imaging and wearables/ "quantified self" measurements. All elements are optional. Molecular assessments will be conducted using peripheral blood samples, and potentially urine, stool or saliva samples. Non-invasive imaging assessment will consist of magnetic resonance imaging (MRI) and computerized tomography (CT) scans, ultrasound, and x-ray. All imaging modalities are optional. Other functional assessments, including respiratory, cardiac and other functions, as well as self-quantifiable assessments via wearables, may also be conducted and are optional.

The study will result in longitudinal data collection to inform if any modalities employed here can inform of baseline deviations for individuals. Researchers at study sites will not be blinded to the data being collected during this study.
