Article Abstract
Background: This study is aimed at verifying a hypothetical model of the structural relationship between the recovery process and difficulties in daily life mediated by occupational dysfunction in severe and persistent mental illness (SPMI).
Methods: Community-dwelling participants with SPMI were enrolled in this multicenter cross-sectional study. The Recovery Assessment Scale (RAS), the World Health Organization Disability Assessment Schedule second edition (WHODAS 2.0), and the Classification and Assessment of Occupational Dysfunction (CAOD) were used for assessment. Confirmatory factor analysis, multiple regression analysis, and Bayesian structural equation modelling (BSEM) were determined to analyze the hypothesized model. If the mediation model was significant, the path coefficient from difficulty in daily life to recovery and the multiplication of the path coefficients mediated by occupational dysfunction were considered as each the direct effect and the indirect effect. The goodness of fit in the model was determined by the posterior predictive value (PPP). Each path coefficient was validated with median and 95% confidence interval (CI).
Results: The participants comprised 98 individuals with SPMI. The factor structures of RAS, WHODAS 2.0, and CAOD were confirmed by confirmatory factor analysis to be similar to those of their original studies. Multiple regression analysis showed that the independent variables of RAS were WHODAS 2.0 and CAOD, and that of CAOD was WHODAS 2.0. The goodness of fit of the model in the BSEM was satisfactory with a PPP = 0.27. The standardized path coefficients were, respectively, significant at -0.372 (95% CI: -0.586, -0.141) from "difficulty in daily life" to "recovery" as the direct effect and at -0.322 (95% CI: -0.477, -0.171) mediated by "occupational dysfunction" as the indirect effect.
Conclusions: An approach for reducing not only difficulty in daily life but also occupational dysfunction may be an additional strategy of person-centered, recovery-oriented practice in SPMI.

Long-duration spaceflight exposes astronauts to various stressors that can alter human physiology, potentially causing immediate and long-term health effects. These stressors can damage biomolecules, cells, tissues, and organs, leading to adverse outcomes. Developing adverse outcome pathways (AOPs) relevant to radiation exposure can guide research priorities and inform risk assessments of future space exploration activities.

Animal studies indicating an association of exposure to extremely low frequency electromagnetic fields (ELF-EMFs) and noise with reproductive dysfunctions. Nonetheless, the potential impacts of exposure to these hazardous agents on the human prostate gland remain unidentified. To assess the relationship between co-exposure to ELF-EMF and noise and the levels of prostate-specific antigen (PSA), a longitudinal study was conducted over eight years among workers at a thermal power station from 2016 to 2024.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global health concern, particularly among individuals with obesity. While metabolic and behavioral risk factors have been well described, the role of psychosocial determinants, such as weight stigma, remains underexplored.
Objectives: To assess the association between sociodemographic variables, healthy lifestyle behaviors, and internalized weight stigma with MASLD risk in a large cohort of obese workers across Spain.

Cadmium (Cd) is a heavy metal that exhibits strong carcinogenic properties and promotes breast cancer (BC) progression. Autophagic flux dysfunction is involved in Cd-induced BC progression, but the underlying molecular mechanisms remain unclear. Here, it is observed that impaired autophagic flux and metabolic reprogramming are notable features related to Cd-induced proliferation, migration, and invasion in BC cell lines, including T-47D and MCF-7 cells.

Objective: To investigate the neural and molecular correlates of occupational burnout in nurses by integrating resting-state fMRI (rs-fMRI), clinical assessments, brain-wide gene expression, and neurotransmitter atlases.
Methods: Fifty-one female nurses meeting burnout criteria and 51 matched healthy controls underwent 3 T rs-fMRI. We analyzed fractional amplitude of low-frequency fluctuations (fALFF) and seed-based functional connectivity (FC), correlating findings with burnout (emotional exhaustion [EE], depersonalization [DP], and personal accomplishment [PA]).
