Firefighters constitute a high-risk group for depression and alcohol use disorders (AUDs) due to frequent exposure to trauma. Perceived job stress and resilience are powerful factors affecting the occurrence of depression and AUDs; however, research on this subject is scarce. ⋯ The cross-sectional study design and self-report nature of the assessment tools limit the current findings.

Randomized Controlled Trial
The effects of omega-3 and vitamin E co-supplementation on parameters of mental health and gene expression related to insulin and inflammation in subjects with polycystic ovary syndrome.
The aim of this study was to evaluate the effects of omega-3 and vitamin E co-supplementation on parameters of mental health and gene expression related to insulin and inflammation in subjects with polycystic ovary syndrome (PCOS). ⋯ Omega-3 and vitamin E co-supplementation was effective in improving parameters of mental health, and gene expression of PPAR-γ, IL-8 and TNF-α of women with PCOS.

Although longitudinal trajectories of post-traumatic stress disorder (PTSD) are well-established in general trauma populations, very little is known about the trajectories of birth-related PTSD. This study aimed to identify trajectories of birth-related PTSD; determine factors associated with each trajectory; and identify women more likely to develop birth-related PTSD. ⋯ Identified factors may inform preventive and treatment interventions for women with traumatic birth experiences.

Posttraumatic stress disorder (PTSD) is a complex psychiatric illness that can be difficult to diagnose, due in part to its comorbidity with major depressive disorder (MDD). Given that researchers have found no difference in prevalence rates of PTSD and MDD after accounting for overlapping symptoms, the latent structures of PTSD and MDD may account for the high comorbidity. In particular, the PTSD Negative Alterations in Cognition and Mood (NACM) and Hyperarousal factors have been characterized as non-specific to PTSD. Therefore, we compared the factor structures of the Diagnostic and Statistical Manual of Mental Disorders, 5thedition (DSM-5) PTSD and MDD and examined the mediating role of the PTSD NACM and Hyperarousal factors on the relationship between MDD and PTSD symptom severity. ⋯ Implications concerning the shared somatic complaints and psychological distress in the comorbidity of PTSD and MDD are discussed.

Social anxiety disorder (SAD) and depressive symptoms often covary. Yet, uncertainty still abounds vis-à-vis the individual symptom-to-symptom associations between these two disorders. Inspired by the network approach to psychopathology that conceptualizes comorbidity as a natural consequence arising from bridge symptoms that can transmit activation from one disorder to the other, we applied network analytic methods to characterize the associations among core symptoms of SAD-i.e. fear and avoidance of social situations-and comorbid depressive symptoms among 174 individuals with DSM-IV-TR criteria for SAD. ⋯ This study adds to a small but growing empirical literature revealing that the co-occurrence between two disorders is best portrayed as sets of symptom-to-symptom connections. As some individual symptoms show differential association in the co-occurrence between SAD and depression, those symptoms may be valuable targets for future research and treatment.
