Blue collar workers generally report high job stress and are exposed to loud noises at work and engage in many of risky health behavioral factors, all of which have been associated with poor sleep quality. However, sleep quality of blue collar workers has not been studied extensively, and no studies have focused Operating Engineers (heavy equipment operators) among whom daytime fatigue would place them at high risk for accidents. Therefore, the purpose of this study was to determine variables associated with sleep quality among Operating Engineers. This was a cross-sectional survey design with a dependent variable of sleep quality and independent variables of personal and related health behavioral factors. A convenience sample of 498 Operating Engineers was recruited from approximately 16,000 Operating Engineers from entire State of Michigan in 2008. Linear regression was used to determine personal and related health behavior factors associated with sleep quality. Multivariate analyses showed that personal factors related to poor sleep quality were younger age, female sex, higher pain, more medical comorbidities and depressive symptoms and behavioral factors related to poor sleep quality were nicotine dependence. While sleep scores were similar to population norms, approximately 34 % (n = 143) showed interest in health services for sleep problems. While many personal factors are not changeable, interventions to improve sleep hygiene as well as interventions to treat pain, depression and smoking may improve sleep quality resulting in less absenteeism, fatal work accidents, use of sick leave, work disability, medical comorbidities, as well as subsequent mortality.

Taurine is one of the most abundant amino acids in the central nervous system, and it has various important functions as a neuromodulator and antioxidant. Taurine is expected to be involved in the mental disorders such as depression; however, knowledge of its function in relation to depression is limited. In this research, we tried to elucidate the effects of taurine supplementation on antidepressant-like behaviors in rats and depression-related signal transduction in the hippocampus. In behavioral tests, rats fed a high taurine (HT: 45 mmol/kg taurine) diet for 4 weeks (HT4w) showed decreased immobility in the forced swim test (FS) compared to controls. On the other hand, rats fed a low taurine (LT: 22.5 mmol/kg taurine) diet for 4 weeks or an HT diet for 2 weeks (HT2w) did not show a significant difference in FS compared to controls. In western blot analyses, the expression of glutamic acid decarboxylase (GAD) 65 and GAD67 in the hippocampus was not affected by taurine supplementation. However, the phosphorylation levels of extracellular signal-regulated kinase1/2 (ERK1/2), protein kinase B (Akt), glycogen synthase kinase3 beta (GSK3?), and cAMP response element-binding protein (CREB) were increased in the hippocampus of HT4w and HT2w rats. Phosphorylated calcium/calmodulin-dependent protein kinase II (CaMKII) was increased in the hippocampus of HT4w rats only. Moreover, no significant changes in these molecules were observed in the hippocampus of rats fed an HT diet for 1 day. In conclusion, our discoveries suggest that taurine supplementation has an antidepressant-like effect and an ability to change depression-related signaling cascades in the hippocampus.

We investigated self-image, psychological functioning, and quality of life in children and adolescents with juvenile idiopathic arthritis (JIA). Thirty-nine children with JIA were compared with 80 healthy peers. We first administered the Human Figure Drawing Test (HFDT) to all subjects; children also completed standardized questionnaires evaluating health-related quality of life (PEDSQL™ 4.0 Generic Core Scales) and the main aspects of psychological functioning: anxiety (SAFA-A) and depression (CDI). Parents were asked to complete the Child Behaviour Checklist (CBCL) and the PEDSQL™ 4.0. For each patient with JIA, clinical notes were gathered and a global disease assessment (visual analog scale–VAS) was performed. Compared to healthy peers, patients with JIA reported reduced maturity quotients at HFDT, more depressive traits, greater anxiety, and lower health-related quality of life. Among the subjects with JIA, HFDT revealed that adolescents had a greater impairment in all areas investigated. Furthermore, there was a significant correlation between the physical well-being rated by VAS and the perception of poorer quality of life in patients, mostly in the psychosocial domains. Children and adolescents with JIA exhibit emotional difficulties and a delay of psychological development leading to low self-esteem, a distorted self-image, more anxiety and depression traits, and a worse quality of life, when compared to healthy subjects.
