Precent about this study aims to examine the joint effect of H. pylori infection and tobacco smoking on the development of stomach cancer among Vietnamese men. A total of 80 stomach cancer cases and 146 controls were recruited in a case - control study conducted in a general hospital. Information on sociodemographic, anthropometric characteristics, tobacco smoking, and the dietary pattern was obtained based on a semi - quantitative food frequency and demographic lifestyle questionnaire; venous anti - H. pylori IgG antibodies were tested by ELISA. Unconditional logistic regression analysis with adjustment for potential confounding was performed to estimate the association between target exposures and stomach cancer, Results: An increase of antibody level was related to an elevated odds of stomach cancer (The fifth versus bottom quintile, OR = 3.07; 95%CI: 1.16, 8.12; p for trend = 0.032). Compared to participants who are negative with both H. pylori infection and tobacco smoking (either cigarette or waterpipe tobacco), individuals exposed to both these factors showed significantly greater odds of stomach cancer (OR = 3.58. (95%CI: 1.32, 9.76, p = 0.013). The similar combined impact of H. pylori infection and tobacco smoking were found in individuals who smoked a cigarette (excluded exclusive waterpipe tobacco smokers, ORs = 3.17; 95%CI: 1.13, 8.94, p = 0.029) or waterpipe tobacco (excluded exclusive cigarette smokers; OR = 3.96, 95%CI: 1.28, 12.26, p = 0.017). The present study suggests an interaction between H. pylori infection and tobacco smoking, even waterpipe tobacco, to induce stomach cancer.

This paper is to present a novel model of estimating trustworthiness 6 a truster on a trustee based on experience trust and reputation trust from some community xvii: 131- context of user‘s topic interests. Firstly, we construct a measure of experience topic-21mm:-which isdefined as a function of degrees of interaction from a truster to some trustee and a ties-interests in topics. Secondly, we construct a measure of reliability degree of conic-.137: on some trustee by means of a function which is computed via degrees of reliability of truster members of the community and similarity of these members with the trustee. Thirdly. we propose a (imposition function for estimating an overal topic-aware trust based on experience topic—aware trust and the reputation topic-aware trust. Our experimental results show that the degree of experience topic- aware trust depends on interaction degree among truster and trustee more than on trustee‘s interest degree. They also indicate that the overall topic-aware trust estimation depends on reputation from community more than user’s own experience evaluation.
