RESUMO
BACKGROUND/AIMS: To evaluate the efficacy of on-demand strategy with proton pump inhibitors (PPIs) in mild gastroesophageal reflux disease (GERD). METHODOLOGY: A literature search was conducted to identify randomized controlled clinical trials which investigating on-demand treatment with PPIs in mild GERD. The control group should be placebo or once-daily treatment. Comparison of treatment effect was performed. RESULTS: Eight studies met the inclusion criteria, of which six were compared with placebo, two others with once-daily treatment. The percentage of patients unwilling to continue the study was 12.1% in the on-demand group while 39.6% in the placebo group. The meta-analysis revealed a statistically significant difference between the two groups (RR: 0.32; 95% CI: 0.23, 0.43). We obtained a similar result when compared with once-daily treatment (RR: 0.52; 95% CI: 0.34, 0.79). CONCLUSIONS: This meta-analysis indicates that on-demand therapy with PPIs is superior to placebo or once-daily treatment in terms of mild GERD.

Background. Specific dietary components have been associated with gastroesophageal reflux disease (GERD) in Europe and the United States. However, the relationship between dietary components and GERD in Chinese still remains unclear. Methods. A total of 268 patients who were newly diagnosed as reflux esophagitis (RE) in Outpatient Endoscopy Center of Tongji Hospital were recruited. In addition, 269 sex- and age-matched subjects were also recruited as controls. The body measurements were determined, and the dietary intake during the previous year was evaluated using food frequency questionnaire (FFQ). Stepwise multiple logistic regression analysis was performed to examine the association between nutrients and RE. Results. After adjustment for WC, WHR, total energy intake, and demographics, there were a positive dose-response relationship between RE and calcium, meat, oils, and salt and a negative dose-response relationship between RE and protein, carbohydrate, calories from protein (%), vitamin C, grains and potatoes, fruits, and eggs. Conclusion. High intake of meat, oils, salt, and calcium is associated with an increased risk for RE while high intake of protein, carbohydrate, calories from protein (%), vitamin C, grains and potatoes, fruits, and eggs correlates with a reduced risk for RE.
RESUMO
The title compound, C(15)H(12)N(2)O, is a derivative of 4-(amino-meth-yl)benzonitrile, an important pestcide inter-mediate. In the crystal structure, mol-ecules are linked via inter-molecular N-Hâ¯O hydrogen bonds, forming infinite chains.
