The overall prevalence rate of sleep problems among clinical nurses in general hospitals in mainland China was high. Many factors could affect the sleep quality of nurses, although occupational stress facilitates development of sleep problems. Various risk factors associated with sleep problems among nurses should be studied extensively and measures for relieving occupational stress should be undertaken.

Liver fibrosis is associated with liver-related outcomes, yet often remains underdiagnosed in primary care settings. Hyperuricemia is associated with non-alcoholic fatty liver disease (NAFLD), but the relationship between hyperuricemia and liver fibrosis remains unclear. Data on individuals without NAFLD is also limited. We investigated the association between hyperuricemia and liver fibrosis in subjects with and without NAFLD. This study recruited 11,690 relevant participants from a health-checkup center. NAFLD was based on ultrasonography. Hyperuricemia was defined as serum uric acid > 6.0 mg/dL in women and >7.0 mg/dL in men. Significant liver fibrosis was diagnosed with the aspartate aminotransferase to platelet ratio index ≥0.5. The following were positively associated with significant liver fibrosis: hyperuricemia (p = 0.001), age ≥ 65 years (p < 0.001), male gender (p < 0.001), obesity (p = 0.009), hypertension (p = 0.002), diabetes (p < 0.001), and NAFLD (p < 0.001) in the logistic regression. The positive association of hyperuricemia with significant liver fibrosis remained in subjects with NAFLD (p = 0.001), but not in subjects without NAFLD. In conclusion, hyperuricemia increased the associated risk of significant liver fibrosis. The positively associated risk existed in subjects with NAFLD, but not in those without it.

Neuroticism may have great impact on mental and physical health in both sexes. The aims of this study were to explore whether relationships between neuroticism scores and psychosocial indicators as well as metabolic syndrome in a population of incoming university students existed in the different sexes. In total, 4266 incoming students were included in this study. The test battery comprised a self-administered structured questionnaire, including the neuroticism subscale of the Maudsley Personality Inventory, the 12-item Chinese Health Questionnaire, the Chinese Internet Addiction Scale-Revision, the measurement of support functions, and the Pittsburgh Sleep Quality Index. Multivariate logistic regression showed that higher Pittsburgh Sleep Quality Index scores, higher Chinese Internet Addiction Scale-Revision scores, and higher 12-item Chinese Health Questionnaire scores were significantly correlated with neuroticism in both sexes, but lower perceived routine support: measurement of support functions scores were associated only with the male participants. No significant differences were found in terms of body mass index or other metabolic profiles. Individuals with poorer mental health and a poorer personal lifestyle had higher neuroticism scores, and sex effects may influence the scale of perceived social support in the neuroticism group. However, the lack of an association between neuroticism score and metabolic syndrome may be due to the recruitment of younger participants in this study.
