Mep25-019	Associations of Chemical Exposures with Psychological Distress and Depression Diagnosis among Waste Pickers in Brasilia, Brazil: A Cross-Sectional Study
	Quote:	Conclusion These associations highlight the need to consider policy level protections for waste pickers to reduce chemical exposure and guard against psychological distress. Further research is necessary to explore which specific chemicals, within broad chemical categories, are associated with psychological distress and depression.
	Comment:	If you are reducet to picking waste for a living, you are under stress regardless of chemical exposure.

We previously showed that CHS symptoms are associated with several behavioral and psychological characteristics linked to psychosocial impairment.

Respondents who were younger, female, identified as non-White, had lower income, had lower educational attainment, and endorsed cannabis-related use problems were more likely to be in the CHS symptom group than in the daily cannabis use group.

Mpy25-006	Factor Analysing Predictive Processing: No Evidence for a General Factor Across Tasks
	Quote:	Background Hypothesis Dysfunctional predictive processing (PP), specifically the aberrant weighting of priors, is a frequently-proposed mechanism for psychosis and psychosis-like phenomena (schizotypy).... Conclusions These results do not evidence a single factor underpinning PP performance. It is therefore inappropriate to use results from single tasks to propose a generalised PP deficit in psychosis. Variation was also not captured by a two-factor hierarchical model of priors.

Mpy25-010	Adverse Childhood Experiences Reorganise the Brain-Personality Network Across the Psychosis Spectrum
	Quote:	These changes converge with a reduced thickness of the frontal executive regions, the brains control centres, identified in our models. Collectively, our results suggest a structuralphenomenological decoupling, where trauma-conditioned affective circuits may bypass weakened top-down regulatory controls. These findings highlight the necessity of using integrative frameworks to capture how trauma fundamentally reshapes the relationship between the brain and schizotypal personality.

These alterations, along with the selective MDm-dACC association with symptom severity, nominate MDm-centered circuit as a hypothesis-generating focus for future mechanistic neuromodulation studies.

These findings contribute to the evidence that disruption of sleep and circadian timing may have a primary role in the mechanisms that mediate autistic traits.

Mpy25-019	The Effects of Serotonergic systems on Cognitive Flexibility and Perseverative Thinking: a comparison between SSRI, classical psychedelics, and acute tryptophan depletion in a Multilevel Meta-Analysis
	Quote:	Conclusions Serotonergic interventions robustly reduce perseverative thinking but do not consistently alter performance on laboratory measures of cognitive flexibility. These findings suggest that serotonin may influence cognitive-emotional rigidity and the subjective experience of repetitive thought more strongly than objective executive task performance. The dissociation between task-based and phenomenological outcomes aligns with contemporary models of serotonergic plasticity and highlights perseverative thinking as a potentially transdiagnostic therapeutic target of serotonergic interventions.

	Quote:	transdiagnostic dimensions revealed more coherent associations with higher-order cognition than symptom-level analyses, highlighting the added value of examining psychopathology at the factor rather than the symptom level. These findings portray a hierarchical view of cognitive dysfunctions in psychopathology and point to representational and metacognitive processes as potential targets for transdiagnostic intervention.
