Contact X-ray Brachytherapy as a Boost Therapy After Neoadjuvant (Chemo)Radiation in High-Risk Locally Advanced Rectal Cancer.

Purpose: Radical surgery following neoadjuvant therapy is the standard of care for locally advanced rectal cancer. A contact x-ray brachytherapy (CXB) boost can alternatively be used to treat residual disease postneoadjuvant (chemo)radiation, especially in patients who are not suitable for or do not wish to have surgery. Its role has mostly been studied to date in low- to intermediate-risk patients.

Do Perineuronal Nets Stabilize the Engram of a Synaptic Circuit?

Perineuronal nets (PNNs), a specialized form of extra cellular matrix (ECM), surround numerous neurons in the CNS and allow synaptic connectivity through holes in its structure. We hypothesize that PNNs serve as gatekeepers that guard and protect synaptic territory and thus may stabilize an engram circuit. We present high-resolution and 3D EM images of PNN-engulfed neurons in mice brains, showing that synapses occupy the PNN holes and that invasion of other cellular components is rare.

Improvements in Clinical Cancer Care Associated with Integration of Personalized Medicine.

Background: While adoption of personalized medicine (PM) continues to increase in clinical oncology, there is limited data connecting the level of PM adoption at a given institution to improved clinical outcomes for patients. The purpose of this study was to analyze the correlation between health care providers' scores on a previously described PM integration framework and two outcome measures: the use of targeted therapy and clinical trial enrollment.

Methods: This study was conducted using real-world data (RWD) from the Syapse Learning Health Network (LHN).
