This study aims to evaluate the efficacy and effectiveness of a mindfulness-based stress reduction (MBSR) program in improving sleep in cancer survivors. Four electronic databases (Cochrane Library, EMBASE, PubMed, and PsycARTICLES) were searched for randomized controlled trials evaluating the effects of MBSR on the sleep of cancer survivors from their inception to May 2020. The primary outcome was sleep quality measured by validated questionnaires such as the Insomnia Severity Index and Pittsburgh Sleep Quality Index. The secondary outcomes were sleep parameters obtained from a sleep diary, polysomnography, and actigraphy. The included studies were critically appraised by the Cochrane risk of bias tool and meta-analyzed. Ten studies were included, and nine studies were analyzed quantitatively. MBSR significantly improved sleep quality compared to usual care (standardized mean difference -0.29, 95 % confidence interval -0.55 to -0.04, I2 = 58 %). However, there were no favorable results with sleep parameters. Compared to active controls, MBSR presented mixed results with sleep quality according to the outcomes and negative results with sleep parameters. This review suggests that MBSR helps cancer survivors improve sleep quality. Our results support the possibility of using MBSR for cancer survivors. However, its efficacy and effectiveness in improving sleep quality and sleep parameters are inconclusive because the number of included studies was few with inconsistent results. Further studies with high methodological quality are required to establish conclusive evidence about the efficacy and effectiveness of MBSR in improving sleep quality and sleep parameters in cancer survivors.

Background: Distressed individuals in Korea may benefit from the practice of mind–body exercises such as Qigong. However, the effectiveness of such techniques needs to be investigated. Methods: Fifty participants who were eligible to this study were randomized into a group receiving a 4-week intervention of a brief Qigong-based stress reduction program (BQSRP) or a wait-list control group. Before and after the intervention period, saliva samples were collected and questionnaires were completed on perceived stress, anxiety, “Hwa-Byung” (anger syndrome), and quality of life. Salivary cortisol has emerged in mind-body therapy research as an easy-to-collect, relatively inexpensive, biologic marker of stress. Salivary corisol were collected to evaluate physiological effect of BQSRP. Between-group comparisons of change from baseline to study completion were analyzed by analysis of covariance for the Perceived Stress Scale and independent two sample t- tests for other measures. Results: Compared with the control group, the BQSRP intervention group displayed significantly larger decreases in Perceived Stress Scale scores (p = 0.0006), State Anxiety scores (p = 0.0028), Trait Anxiety scores (p < 0.0001), personality subscale scores of the Hwa-Byung Scale (p = 0.0321), symptoms scores of the Hwa-Byung Scale (p = 0.0196), and a significantly larger increase in World Health Organization Quality of Life Abbreviated version scores (p s < .05). Salivary cortisol levels were not changed. Conclusions: The BQSRP appears to be effective in reducing stress perception, anxiety, anger, and improving quality of life (KCT0000056).

Background: Soyo-san is a traditional oriental medicinal formula, a mixture of 9 crude drugs, and it has been clinically used for treating mild depressive disorders. The role of pro- and anti-inflammatory cytokines in psychiatric disorders has been the focus of great research attention in recent years. In the present study, we detected the antidepressant effect of soyo-san in the ovariectomized and repeated stressed female rats.Methods: This study was designed to evaluate the antidepressant-like effect of soyo-san on the forced swimming test (FST). The rats were randomly divided into the following groups: the nonoperated and nonstressed group (non-op), the nonoperated and stressed group (non-op + ST), the ovariectomized and stress group (OVX) and sham operated and stressed group (sham), the ovariectomized and stressed group (OVX + ST), the ovariectomized, stressed and soyo-san 100 mg/kg treated group (SOY100) and the ovariectomized, stressed and soyo-san 400 mg/kg treated group (SOY400). The rats were exposed to immobilization stress (IMO) for 14day (2 h/14day), and soyo-san (100 mg/kg and 400 mg/kg) was administrated during the same time. In the same animals, the levels of corticosterone and interleukin-1-beta (IL-1β) were examined in the serum. Also, the change of IL-1β expression in brain regions was examined after behavior test.Results: In the FST, the lower dose (100 mg/kg) of extract was effective in reducing immobility, along with an increase in swimming time. The serum levels of corticosterone and IL-1β in the SOY groups were significantly lower than those in the control group. In the brain, the expression of IL-1β positive neurons in the control group were significantly increased in the paraventricular nucleus (PVN) and hippocampus compared to the non-op. However, soyo-san groups significantly reduced the IL-1β-ir neurons in the PVN and hippocampal regions compared to the control.Conclusion: The present results demonstrated that soyo-san effectively reduced behavioral and patho-physiological depression-like responses. Trial registration: Our results suggest that soyo-san may be useful for immune regulator in repeated stress-induced ovariectomized female rats.

Hwabyung is a psychosomatic disease resulting from the suppression of anger over an extended period. The Emotional Freedom Techniques (EFT) are meridian-based psychotherapy known to cure many psychosomatic diseases, and progressive muscle relaxation (PMR) is a therapeutic method that relieves physical and psychological tension by repeated tensing and relaxation of the muscles. In this study, we compared the effects of EFT and PMR in patients with Hwabyung. 40 patients were enrolled and randomized to receive 4 weeks of group sessions with either EFT (n = 20) or PMR (n = 20). Evaluations were conducted pre- and post-treatment and at 4-week and 24-week follow-ups after session end. The Hwabyung Scale, Visual Analogue Scale of Hwabyung Symptoms (VAS-HS), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and State-Trait Anger Expression Inventory (STAXI) were administered as self-report tools. The analysis excluded 8 patients who never attended treatment and 1 patient meeting the exclusion criteria. EFT (n = 15) and PMR (n = 16) improved Hwabyung symptoms (-13.95% and -11.46%, respectively), state anxiety (-12.57% and -12.64%, respectively), and depression (-32.11% and -18.68%, respectively) (p < 0.05 for all). Trait anger improved in EFT group (-13.4%, p = 0.004). There were no significant differences between the groups (p > 0.05) except for trait anger at post-treatment (p = 0.022 for between group). No adverse events were reported during the study.
