An analysis of adverse event reports from the FDA adverse event reporting system between 2019 and 2023 identified 14,606 reports in which esketamine nasal spray was the primary suspected drug. Psychiatric disorders accounted for 33.20% of the 518 distinct adverse event signals, followed by nervous system disorders (16.67%) and general disorders (14.21%). Dissociation was the most frequent and intense signal, reported 1,093 times. Uncommon but strong signals included hand-eye coordination impaired, feeling guilty, and feelings of worthlessness. Dissociative disorder, not listed in the product's summary of product characteristics, also showed a strong signal. Close clinical attention to psychiatric and nervous system adverse events is warranted.
A meta-analysis of ten randomized controlled trials involving 912 nurses found that mindfulness-based training (MBT) reduces stress and job burnout. MBT lowered stress levels and job burnout. The analysis found no evidence of publication bias. The results suggest MBT is a promising short-term strategy for alleviating stress and burnout among nursing professionals, but further research is needed to assess the durability of its effects.
Structured visual streams containing regularities—whether perceptual (shape, motion) or semantic (idioms)—dominate over unstructured streams in the competition for visual awareness during binocular rivalry. Perceptual- and semantic-level regularities produce rivalry advantages that dissociate: perceptual regularities operate via nonconscious temporal integration and are vulnerable to disruptions of the spatiotemporal integration window, whereas semantic regularities operate via conscious temporal integration and are not. These findings indicate that structure-guided information integration across time contributes to visual awareness through at least two distinct mechanisms, supporting theories that link integration to conscious experience.
