Background And Aims: We sought to develop a minimally-invasive, robust, accessible nonendoscopic strategy to diagnose Barrett's esophagus (BE), esophageal adenocarcinoma (EAC), and its immediate precursor lesion, high-grade dysplasia (HGD) based on methylated DNA biomarkers applied to a retrievable sponge-capsule device in a cohort representative of the BE population (i.e., mostly short-segment, non-dysplastic BE, NDBE).

- Ductal carcinoma in-situ (DCIS) is a non-invasive breast cancer type that makes up about 25% of breast cancer cases, but it often leads to unnecessary aggressive treatment despite many cases never progressing to invasive cancer.
- A study analyzed 197 breast tissue samples to explore molecular changes in DCIS, using techniques like mRNA expression and DNA analysis to compare progressing versus non-progressing cases.
- The research found significant molecular differences among DCIS subtypes and between DCIS and invasive breast cancer, highlighting the complexity of DCIS and the need for more tailored approaches to assess risk and treatment.
Uncertainty of adolescent brain maturation sex difference claims.

Article Synopsis
- * In a Phase II clinical trial, 27 patients received entinostat followed by nivolumab, resulting in an objective response rate of 11% and a median response duration of over 10 months, although the primary endpoint for overall effectiveness was not reached.
- * The combination treatment led to significant immune profile changes, including increased dendritic cell activity and enhanced inflammatory response, suggesting potential for improving treatment strategies in PDA despite
Functional Brain Connectivity Predictors of Prospective Substance Use Initiation and Their Environmental Correlates.
Biol Psychiatry Cogn Neurosci Neuroimaging
October 2024
Background: Early substance use initiation (SUI) places youth at substantially higher risk for later substance use disorders. Furthermore, adolescence is a critical period for the maturation of brain networks, the pace and magnitude of which are susceptible to environmental influences and may shape risk for SUI.
Methods: We examined whether patterns of functional brain connectivity during rest (rsFC), measured longitudinally during pre- and early adolescence, can predict future SUI.
