However, it is unknown whether this affects the health-seeking behaviour of residents in rural communities. We examined whether the rurality-related index of a community was associated with the participation rate of residents in community-based preventive health services. Based on the national census data on all the 1816 municipalities in Japan in 2007, the correlation was evaluated between the participation rate in cancer screening (stomach cancer, colorectal cancer) or influenza vaccination programmes among those older than 65, and each of the municipality-level variables. The correlations were examined by simple correlation and multiple regression analyses. The correlations were also evaluated between voting rate (a parameter of people's engagement in community activities) and each municipality-level variable with multiple regression analysis. Simple correlation analysis showed that the population density was negatively correlated with the participation rate of all (stomach cancer, colorectal cancer, and influenza) preventive programmes (r = -0.367, -0.171 and -0.188, respectively; each p < 0.001). The significant correlations were maintained even after adjustment for other socioeconomic factors in multiple regression analysis in stomach cancer screening and influenza vaccination (beta = -0.279 and -0.133, respectively: each p < 0.05). Population density was negatively correlated with voting rate (beta = -0.488: p < 0.001). Residents in rural communities were more likely to participate in community-based mass preventive services and were more actively engaged in political activities than their urban counterparts. These results suggest that rural residents have a stronger sense of community, and this could potentially facilitate residents' engagement in mass preventive services.</p>","PeriodicalId":12860,"journal":{"name":"Hiroshima journal of medical sciences","volume":"62 3","pages":"43-8"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"31904351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examined the relationship between inflammatory mechanisms and both bone absorption and the proliferation of epithelial cholesteatoma cells. Cultured cholesteatoma epithelial cells were stimulated by lipopolysaccharide (LPS) and dexamethasone (Dex). We found that the expression of receptor activator of NF-kappaB ligand (RANKL) and Ki-67 in cultured cholesteatoma cells was increased by LPS stimulation, indicating that LPS promotes not only bone destruction but also the proliferative activities of these cells. The constitutive expression of RANKL and Ki-67 and the production of IL-6 and IL-8 were significantly inhibited by Dex treatment. Further, Dex significantly suppressed the stimulatory effects of LPS on RANKL and Ki-67 expression and on IL-6 and IL-8 production. Based on results so far, Dex likely exerts a beneficial action against acute inflammation.

In the neurocognitive assessments, the score for disinhibition with aripiprazole was significantly lower than with risperidone (p < 0.05). In addition, serum prolactin levels were significantly lower with aripiprazole (p < 0.001). The treatment drop-out rate was higher for patients receiving aripiprazole than risperidone.
