Metabolic syndrome, with a high global incidence, is characterized by central obesity, elevated fasting blood glucose, high blood pressure, and abnormal lipid levels, including reduced high-density lipoprotein cholesterol and elevated triglycerides. These metabolic dysfunctions can lead to neurotransmitter alterations and dysregulation of the hypothalamic-pituitary-adrenal axis. These changes, in turn, contribute to mental disorders such as depression and anxiety. Adipokines, secreted from adipose tissue, modulate various metabolic processes, neurotransmission, and immune responses. The interplay between adipokines and neurotransmitters may be a critical component underlying the interaction between metabolic abnormalities and mental disorders. This review aims to discuss the brain-metabolism axis, focusing on altered levels of adipokines and neurotransmitters in metabolic and mental disorders.

Background: Screening for cognitive impairment in primary care is important, yet primary care physicians (PCPs) report conducting routine cognitive assessments for less than half of patients older than 60 years of age. Linus Health's Core Cognitive Evaluation (CCE), a tablet-based digital cognitive assessment, has been used for the detection of cognitive impairment, but its application in primary care is not yet studied.

Objective: This study aimed to explore the integration of CCE implementation in a primary care setting.

Navigating Dual-Harm: Integrating Self- and Other-Harm Into Public Health Inquiry.

Am J Public Health

April 2025

Diego A. Díaz-Faes and Charles C. Branas are with the Mailman School of Public Health and Sonali Rajan is with Teachers College, Columbia University, New York, NY.

Dual-harm, the co-occurrence of self- and other-harm, recognizes the overlap between these outcomes of aggressive behavior and their potential shared causes. Little progress has been made in preventing and responding to dual-harm in the broader population, and it remains understudied in public health research. We posit that the scientific investigation of dual-harm would greatly benefit from the application of public health principles and methods.

Associations of perceived discrimination with health outcomes and health disparities in the All of Us cohort.

J Am Med Inform Assoc

March 2025

National Institute on Minority Health and Health Disparities, National Institutes of Health, Rockville, MD 20818, United States.

Objectives: The goal of this study was to investigate the association of perceived discrimination with health outcomes and disparities.

Materials And Methods: The study cohort consists of 60 180 participants from the 4 largest self-identified race and ethnicity (SIRE) groups in the All of Us Research Program participant body: Asian (1291), Black (4726), Hispanic (5336), and White (48 827). A perceived discrimination index (PDI) was derived from participant responses to the "Social Determinants of Health" survey, and the All of Us Researcher Workbench was used to analyze associations and mediation effects of PDI and SIRE with 1755 diseases.

Interoception refers to the sensation of internal and physiological bodily states, such as heart rate, and contributes to the maintenance of bodily internal homeostasis. Some studies showed that interoceptive awareness is related to experiencing nightmares and subjective sleep quality. Similarly to the perception of heart rate variability, sleepiness is thought to be mainly evoked by homeostatic processes and is based on the awareness and recognition of internal body signals.
