- BACKGROUND: Accumulating evidence suggests that alterations in inflammatory biomarkers are important in depression. However, previous meta-analyses disagree on these associations, and errors in data extraction may account for these discrepancies.METHODS: PubMed/MEDLINE, Embase, PsycINFO, and the Cochrane Library were searched from database inception to 14 January 2020. Meta-analyses of observational studies examining the association between depression and levels of tumor necrosis factor-α (TNF-α), interleukin 1-β (IL-1β), interleukin-6 (IL-6), and C-reactive protein (CRP) were eligible. Errors were classified as follows: incorrect sample sizes, incorrectly used standard deviation, incorrect participant inclusion, calculation error, or analysis with insufficient data. We determined their impact on the results after correction thereof.RESULTS: Errors were noted in 14 of the 15 meta-analyses included. Across 521 primary studies, 118 (22.6%) showed the following errors: incorrect sample sizes (20 studies, 16.9%), incorrect use of standard deviation (35 studies, 29.7%), incorrect participant inclusion (7 studies, 5.9%), calculation errors (33 studies, 28.0%), and analysis with insufficient data (23 studies, 19.5%). After correcting these errors, 11 (29.7%) out of 37 pooled effect sizes changed by a magnitude of more than 0.1, ranging from 0.11 to 1.15. The updated meta-analyses showed that elevated levels of TNF- α, IL-6, CRP, but not IL-1β, are associated with depression.CONCLUSIONS: These findings show that data extraction errors in meta-analyses can impact findings. Efforts to reduce such errors are important in studies of the association between depression and peripheral inflammatory biomarkers, for which high heterogeneity and conflicting results have been continuously reported.

- The present study aimed to explore the use of meaning-making coping (existential, spiritual, and religious coping) among cancer patients in Korea and to investigate the impact of culture on their choice of coping methods. Thirty-three participants with various kinds of cancer were interviewed. Four different kinds of coping resources emerged from analyses of the interview transcripts: (1) belief in the healing power of nature; (2) mind–body connection; (3) relying on transcendent power; and (4) finding oneself in relationships with others. The findings of this study suggest the importance of investigating cultural context when exploring the use of the meaning-making coping strategies in different countries.

- The present study compared meaning-making coping among cancer patients in Sweden and South Korea, with a focus on the sociocultural context. Semi-structured interviews were conducted with 51 Swedes and 33 Koreans. The results showed significant differences between the two countries as well as similarities in existential, spiritual, and religious coping. For example, Swedes primarily used meaning-making coping as a means of meditation or relaxation, whereas Koreans relied on coping with prayer and using healthy foods as a means to survive. The present study confirms the significance of investigating cultural context when we explore the use of meaning-making coping among people who have experienced cancer.
