AI Article Synopsis
- The study explored how optimism and pessimism can influence work disability due to depression and the likelihood of returning to work.
- Data was gathered from over 38,000 public sector employees, finding that higher optimism significantly reduced the risk of work disability and increased the chance of returning to work compared to pessimism.
- Optimism was shown to be a stronger predictor of resilience against depression-related work disability than pessimism, highlighting the importance of a positive outlook in workplace mental health outcomes.
Article Abstract
Background: Personality characteristics are assumed to affect to the vulnerability to depression and its outcomes. The aim of this study was to examine optimism and pessimism as predictors of depression-related work disability and subsequent return to work.
Methods: We conducted a prospective cohort study of 38,214 public sector employees with no record of diagnosed depression. Optimism and pessimism were measured using the Revised Life Orientation Test (LOT-R). Records of long-term (>90 days) work disability with a diagnosis of depression and subsequent return to work until the end of 2005 were obtained from the national health registers.
Results: During the mean follow-up of 4.0 (SD=2.3) years, 287 employees encountered work disability with a diagnosis of depression. Of them, 164 (57%) returned to work during the follow-up. One unit increase in the optimism mean score (range 1-4) was associated with a 25% lower risk of work disability due to depression and a 37% higher probability of returning to work after a work disability period when adjusted for age and sex. In the fully-adjusted model hazard ratios per one unit increase in optimism were 0.79 (95% CI 0.66-0.96) for work disability and 1.30 (95% CI 1.01-1.66) for return to work. The pessimism mean score (range 1-4) was only associated with a lower probability of returning to work (fully-adjusted HR per one unit increase 0.66, 95% Cl 0.49-0.88).
Conclusion: The level of optimism was a stronger predictor of work disability with a diagnosis of depression than the level of pessimism, while both optimism and pessimism predicted returning to work.

Background Multiple sclerosis is a chronic, progressive, disabling disease associated with a high rate of infection, evidence of chronic inflammation, and a high mortality rate. Abnormalities of serum cytokines and changes in the activity of inflammatory cells were associated with relapsing-remitting multiple sclerosis (MS-RR). This study aims to introduce new inflammatory ratios derived from hematological and lipid indices as discriminators of T-helper (Th)-1/Th-2 activity in RR-MS.

The recovery process following ischemic stroke is a complex undertaking involving intricate cellular and molecular interactions. Cellular dysfunction or aberrant pathways can lead to complications such as brain edema, hemorrhagic transformation, and glial scar hyperplasia, hindering angiogenesis and nerve regeneration. These abnormalities may contribute to long-term disability post-stroke, imposing significant burdens on both families and society.

Emerging work suggests that the thalamus, the relay center of the brain that undergoes secondary damage after cortical TBI, is involved with heightened seizure risks after TBI. TBI also induces the recruitment of peripheral immune cells, including T cells, to the site(s) of injury, but it is unclear how these cells impact neurological sequelae post-TBI.
