| 1 | Validation of the Rockall scoring system for outcomes from non-variceal upper gastrointestinal bleeding in a Canadian setting显示文摘AIM: To validate the Rockall scoring system for predicting outcomes of rebleeding, and the need for a surgical procedure and death. METHODS: We used data extracted from the Registry of Upper Gastrointestinal Bleeding and Endoscopy including information of 1869 patients with non-variceal upper gastrointestinal bleeding treated in Canadian hospitals. Risk scores were calculated and used to classify patients based on outcomes. For each outcome, we used χ2 goodness-of-fit tests to assess the degree of calibration, and built receiver operating characteristic curves and calculated the area under the curve (AUC) to evaluate the discriminative ability of the scoring system. RESULTS: For rebleeding, the χ2 goodness-of-fit test indicated an acceptable fit for the model [χ2 (8) = 12.83, P = 0.12]. For surgical procedures [χ2 (8) = 5.3, P = 0.73] and death [χ2 (8) = 3.78, P = 0.88], the tests showed solid correspondence between observed proportions and predicted probabilities. The AUC was 0.59 (95% CI: 0.55-0.62) for the outcome of rebleeding and 0.60 (95% CI: 0.54-0.67) for surgical procedures, representing apoor discriminative ability of the scoring system. For the outcome of death, the AUC was 0.73 (95% CI: 0.69-0.78), indicating an acceptable discriminative ability. CONCLUSION: The Rockall scoring system provides an acceptable tool to predict death, but performs poorly for endpoints of rebleeding and surgical procedures. | Robert A Enns Yves M Gagnon Alan N Barkun David Armstrong Jamie C Gregor Richard N Fedorak RUGBE Investigators Group | 2006 | World Journal of Gastroenterology2006，12，48： | 14 |
| 2 | 1998年印度洋珊瑚死亡事件的生态影响和社会经济影响:是ENSO影响和未来变化的警告吗?显示文摘自大约15O年前开始有气温记录以来,1998年是所记录到的最热的一年,20世纪90年代是最热的十年。另外,1998年也是有记录以来厄尔尼诺现象最严重的一年。这一现象产生的结果是,海洋中许多地方的水温很高,尤其是位于热带的印度洋的水温常常比正常年份高3~5℃。该区域内的大量珊瑚脱色并死亡,可能是由于高的水温以及其它气象、气候因子共同作用所致。斯里兰卡、马尔代夫、印度、肯尼亚、坦桑尼亚和塞舌尔群岛的珊瑚礁中珊瑚的死亡率较高,许多浅海区甚至高达90%。在位于印度洋其它地方和距海面20米以下的珊瑚礁中,珊瑚的死亡率通常为50%。因此,1998年珊瑚的死亡情况是空前严重的。印度洋的珊瑚褪色对沿海社区的二级社会经济影响可能是长期的和严重的。除了鱼资源可能减少和对旅游造成不良影响外,侵蚀可能成为一个严重的问题,尤其是在马尔代夫和塞舌尔群岛。如果目前已经发现的全球温度升高的趋势继续下去,那么1998年印度洋珊瑚礁上发生的情况在未来一些年内极有可能加剧并在其它的热带海洋区出现。印度洋的珊瑚礁可能是反映全球气候变化潜在影响的一个重要信号,我们应当对这一警告引起注意。 | Clive Wilkinson OlofLindén Herman Cesar Gregor Hodgson Jaston Rubens Alan E.Strong 李岱青 | 1999 | 人类环境杂志1999，28，2： | 4 |
