  • The present systematic review and meta-analysis was conducted to assess any association between breastfeeding and the risk of ovarian cancer. A systematic search of published studies was performed in PUBMED and EMBASE and by reviewing reference lists from retrieved articles through March 2013. Data extraction was conducted independently by two authors. Pooled relative risk ratios were calculated using random-effect models. Totals of 5 cohort studies and 35 case-control studies including 17,139 women with ovarian cancer showed a 30% reduced risk of ovarian cancer when comparing the women who had breastfed with those who had never breastfed (pooled RR = 0.70, 95% CI: 0.64-0.76; p = 0.00), with significant heterogeneity in the studies (p = 0.00; I2 = 76.29%). A significant decreasd in risk of epithelial ovarian cancer was also observed (pooled RR = 0.68, 95% CI: 0.61-0.76). When the participants were restricted to only parous women, there was a slightly attenuated but still significant risk reduction of ovarian cancer (pooled RR = 0.76, 95% CI: 0.69-0.83). For total breastfeeding duration, the pooled RRs in the < 6 months, 6-12 months and > 12 months of breastfeeding subgroups were 0.85 (95% CI: 0.77-0.93), 0.73 (95% CI: 0.65-0.82) and 0.64 (95%CI: 0.56-0.73), respectively. Meta-regression of total breastfeeding duration indicated an increasing linear trend of risk reduction of ovarian cancer with the increasing total breastfeeding duration (p = 0.00). Breastfeeding was inversely associated with the risk of ovarian cancer, especially long-term breastfeeding duration that demonstrated a stronger protective effect.

  • Purpose: The purposes of this study were to review the research trends and to identify developmental direction of studies on community interventions according to the ecological model for workers with cardiovascular diseases (CVD) risk factors. Methods: Electronic databases including PsycINFO, PubMed, EMBASE, CINAHL, and Cochrane Library and the reference lists of articles were searched. All articles were assessed in relation to inclusion and exclusion criteria, resulting in 29 researches being reviewed. Each review was critically appraised by two authors using a guideline of PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses). Results: Nowadays, interventions in organizational level, integrated and web-based interventions are increasing to prevent CVD risk factors for workers. Even though the importance of psychosocial aspects to prevent CVD, the only 2 studies included psychosocial factors in the outcome variables. Also, 14% among 29 researches were based on theories. Conclusion: Psychosocial factors such as job stress, depression, and emotional labor could be CVD risk factors. Therefore, interventions including psychosocial aspects are needed to prevent workers' CVD risks more effectively. Theory-based interventions are needed to support interventions' effects and to develop the nursing science.

  • Background: Bone mineral density (BMD) is a lifetime marker of estrogen in a woman's body and has been associated with increased breast cancer risk. Nonetheless the actual association is still debatable. Furthermore, estrogen is very crucial in maintaining human bone density and gradually decreases over age. A systematic search was conducted to assess any association of BMD with breast cancer risk factors among premenopausal and postmenopausal women. Materials and Methods: Review identification was performed through databases searching on MEDLINE, CINAHL and SCOPUS and 19 qualified studies were elected. The keywords used were "bone mineral density", "breast cancer", and "breast density". Results: A total of 19 articles showed variation with the majority of the studies focused on postmenopausal and a few focused on premenopausal women. Overall there was no concensus on effects. Conclusions: An enormous effort is being undertaken by researchers to prove that BMD might be one of the significant risk factors for breast cancer.

  • Site or multi-unit (MU) risk assessment has been a major issue in the field of nuclear safety study since the Fukushima accident in 2011. There have been few methods or experiences for MU risk assessment because the Fukushima accident was the first real MU accident and before the accident, there was little expectation of the possibility that an MU accident will occur. In addition to the lack of experience of MU risk assessment, since an MU nuclear power plant site is usually very complex to analyze as a whole, it was considered that a systematic method such as probabilistic safety assessment (PSA) is difficult to apply to MU risk assessment. This paper proposes a new MU risk assessment methodology by using the conventional PSA methodology which is widely used in nuclear power plant risk assessment. The logical failure structure of a site with multiple units is suggested from the definition of site risk, and a decomposition method is applied to identify specific MU failure scenarios.

  • Objectives This study aimed to evaluate the effect of chuna manual therapy (CMT) for postpartum low back pain using a systematic review. Methods We performed a literature search using 12 electronic databases up to the end of September 2021. We included randomized controlled trials (RCTs) that evaluated the effect of CMT in the treatment of postpartum low back pain. The risk of bias was evaluated using the Cochrane risk-of-bias tool. Results Four randomized controlled trials were reported statistically significant effect in pain VAS, ODI and JOA of chuna manual therapy compared with moxibution, electro acupuncture, hyperthermia or usual care. As a result of assessing the risk of bias tool, most of the contents of the evaluation items were not identified, so it was evaluated as an uncertain risk. Conclusions CMT may be effective in treating postpartum low back pain. However, evidence was limited due to the small sample size, lack of well-designed RCTs and regional bias. Further well-designed studies are required to obtain stronger evidence.
