Extracellular Matrix in Synthetic Hydrogel-Based Prostate Cancer Organoids Regulate Therapeutic Response to EZH2 and DRD2 Inhibitors.

Following treatment with androgen receptor (AR) pathway inhibitors, ≈20% of prostate cancer patients progress by shedding their AR-dependence. These tumors undergo epigenetic reprogramming turning castration-resistant prostate cancer adenocarcinoma (CRPC-Adeno) into neuroendocrine prostate cancer (CRPC-NEPC). No targeted therapies are available for CRPC-NEPCs, and there are minimal organoid models to discover new therapeutic targets against these aggressive tumors.

Using objective clinical metrics to understand the relationship between the electronic health record and physician well-being: observational pilot study.

Background: Electronic health records (EHRs) are a significant contributor to physicians' low satisfaction, reduced engagement and increased burnout. Yet the majority of evidence around EHR and physician harms is based on self-reported screen time, which may both over- and underreport actual exposure.

Aims: The purpose of this study was to examine how objective EHR use correlates with physician well-being and to develop preliminary recommendations for well-being-based EHR interventions.

Psychometric properties of a new self-report measure of medical student stress using classic and modern test theory approaches.

Background: Medical students face significant stressors related to the intense rigors of their training and education. Accurate measurement of their stress is important to quickly identify, characterize and ameliorate these challenges. Existing measures have limitations that modern measurement approaches, such as item response theory (IRT), are able to address.

A Systematic Review of Noninvasive Brain Stimulation for Opioid Use Disorder.

Background: There is a great public health need to identify novel treatment strategies for opioid use disorder (OUD) in order to reduce relapse and overdose. Noninvasive brain stimulation (NIBS) has demonstrated preliminary effectiveness for substance use, but little is known about its use in OUD. Neuromodulation may represent a potential adjunctive treatment modality for OUD, so we conducted a systematic review to understand the state of the current research in this field.

Immunomodulatory nanogels overcome restricted immunity in a murine model of gut microbiome-mediated metabolic syndrome.

Biomaterials-based nanovaccines, such as those made of poly(lactic-co-glycolic acid) (PLGA), can induce stronger immunity than soluble antigens in healthy wild-type mouse models. However, whether metabolic syndrome can influence the immunological responses of nanovaccines remains poorly understood. Here, we first show that alteration in the sensing of the gut microbiome through Toll-like receptor 5 (TLR5) and the resulting metabolic syndrome in mice diminish the germinal center immune response induced by PLGA nanovaccines.
