Cognitive Impairment in Nonagenarians: Potential Metabolic Mechanisms Revealed by the Synergy of In Silico Gene Expression Modeling and Pathway Enrichment Analysis.

Previous studies examining the molecular and genetic basis of cognitive impairment, particularly in cohorts of long-living adults, have mainly focused on associations at the genome or transcriptome level. Dozens of significant dementia-associated genes have been identified, including APOE, APOC1, and TOMM40. However, most of these studies did not consider the intergenic interactions and functional gene modules involved in cognitive function, nor did they assess the metabolic changes in individual brain regions.

Prevalence of burnout among psychiatrists: A systematic review and meta-analysis.

Background: Burnout is a consequence of chronic occupational stress exposure. Psychiatrists are prone to burnout due to specific work-related factors. This study examined the burnout prevalence among psychiatrists.
