Background: The use of ecological momentary assessment (EMA) designs has been on the rise in mental health epidemiology. However, there is a lack of knowledge of the determinants of participation in and compliance with EMA studies, reliability of measures, and underreporting of methodological details and data quality indicators.
Objective: This study aims to evaluate the quality of EMA data in a large sample of university students by estimating participation rate and mean compliance, identifying predictors of individual-level participation and compliance, evaluating between- and within-person reliability of measures of negative and positive affect, and identifying potential careless responding.
Head and neck squamous cell carcinoma (HNSCC) can, in rare instances, metastasize to the CNS, which is often associated with a poor prognosis. We present the case of a 65-year-old male with a history of HNSCC who developed two enhancing brain lesions: one in the right parietal region and another in the right insular region. Initially, the patient was managed with CyberKnife radiosurgery targeting both lesions.

Urinary para-hydroxyphenylacetic acid (u-pHPAA), a metabolite of tyrosine, has been proposed as a potential biomarker for these diseases. This study aims to evaluate the effectiveness of u-pHPAA and tyrosine as biomarkers.
