Patient-reported exposures and outcomes link the gut-brain axis and inflammatory pathways to specific symptoms of severe mental illness.

Unlabelled: We developed a "gut-brain-axis questionnaire" (GBAQ) to obtain standardized person-specific "review of systems" data for microbiome-gut-brain-axis studies. Individual items were compared to PANSS symptom measures using dimensional, transdiagnostic and traditional categorical approaches.

Method: Forty psychotic participants, independent of diagnoses, and 42 without psychosis (18 nonpsychotic affective disorders, 24 healthy controls) completed the GBAQ and underwent research diagnostic and symptom assessments.

Sleep-related attitudes, beliefs, and practices among an urban-dwelling African American community: a qualitative study.

Objectives: Short sleep duration and poor sleep quality are more prevalent among African Americans (AAs) and may be a modifiable risk factor for cardiometabolic disorders. However, research is limited about sleep-related attitudes, beliefs, and practices among AAs. Our objective was to evaluate these practices and beliefs surrounding sleep among urban-dwelling AAs.
