Objectives: Stigma is known to be a major barrier to treatment for people who use drugs (PWUD). This study uses the Stigma and Health Discrimination Framework to analyze how different forms of stigma shape experiences in the wake of an overdose incident, and perceptions of the efficacy and utility of postoverdose interventions among a sample of PWUD in Dayton, Ohio-a location with a high overdose rate.

Methods: Interviews were conducted with 23 individuals who self-reported past-month illicit opioid, crack/cocaine, or methamphetamine use who had experienced or witnessed a drug overdose in the past 6 months.

Resting-state functional magnetic resonance imaging (rsfMRI) is a powerful tool for investigating the relationship between brain function and cognitive processes as it allows for the functional organization of the brain to be captured without relying on a specific task or stimuli. In this paper, we present a novel modeling architecture called BrainRGIN for predicting intelligence (fluid, crystallized and total intelligence) using graph neural networks on rsfMRI derived static functional network connectivity matrices. Extending from the existing graph convolution networks, our approach incorporates a clustering-based embedding and graph isomorphism network in the graph convolutional layer to reflect the nature of the brain sub-network organization and efficient network expression, in combination with TopK pooling and attention-based readout functions.
