There is a crucial need to more deeply understand the impact and etiology of bias toward persons with developmental disabilities (PWDD). A largely unstudied area of concern and possible intervention is the portrayal of PWDD in medical education. Often, medical photographs portray PWDD with obscured faces, emotionless, and posed in an undignified way.

Objective: This pilot study aimed to assess the effectiveness of a "room of horrors" (RoH) simulation in identifying patient safety threats in a pediatric emergency department (PED) and to evaluate health care workers' (HCWs') perceptions of the experience.

Methods: We developed an RoH simulation featuring 25 potential safety hazards derived from actual PED incidents and "never events." The teams of physicians and nurses who participated in the simulation identified as many hazards as they could within a 10-minute window followed by a debriefing session during which errors were corrected and missed hazards were pointed out.

Intersectionality has emerged as an important theoretical concept for examining overlapping social hierarchies and has garnered varying interpretations and applications in scholarly discourse. To help organize varied definitions of intersectionality that are commonly used in the social sciences, we propose a typology that distinguishes between primary, pragmatic, and pluralistic intersectionality. In this typology, primary intersectionality centers on Black women and has a social inequity focus, pragmatic intersectionality includes various groups with flexible applications, and pluralistic intersectionality encompasses a broad inclusion of categorizations without an inequity focus.

Background: Sacubitril/valsartan is one of the main foundational medications in heart failure (HF), and recent data show that it provides a mortality benefit in this patient population. Some of the main safety concerns associated with this drug class include hypotension, hyperkalemia, angioedema, and acute kidney injury (AKI). Other studies have focused on sacubitril/valsartan effects on blood glucose levels, which is a newer concept that has not been as researched.

Alzheimer's disease (AD) is a prevalent and debilitating neurodegenerative disease that leads to substantial loss of quality of life. Therapies currently available for AD do not modify the disease course and have limited efficacy in symptom control. As such, novel and precise therapies tailored to individual patients' neurophysiologic profiles are needed.

Major depressive disorder (MDD) is a prevalent and debilitating psychiatric disease that leads to substantial loss of quality of life. There has been little progress in developing new MDD therapeutics due to a poor understanding of disease heterogeneity and individuals' responses to treatments. Electroencephalography (EEG) is poised to improve this, owing to the ease of large-scale data collection and the advancement of computational methods to address artifacts.

Identifying functional biomarkers related to treatment success can aid in expediting therapy optimization, as well as contribute to a better understanding of the neural mechanisms of the treatment-resistant depression (TRD) and subcallosal cingulate deep brain stimulation (SCC-DBS). Magnetoencephalography data were obtained from 16 individuals with SCC-DBS for TRD and 25 healthy subjects. The first objective of the study was to identify region-specific oscillatory modulations that both (i) discriminate individuals with TRD (with SCC-DBS OFF) from healthy controls, and (ii) discriminate TRD treatment responders from non-responders (with SCC-DBS ON).
