While much work has addressed the problem of maintaining materialized views, the important question of optimizing queries in the presence of materialized views has not been resolved. In this paper, we analyze the optimization question and provide a comprehensive and efficient solution. Our solution has the desirable property that it is a simple generalization of the traditional query optimization algorithm.

Interim analysis of the results suggests the superiority of the LERV technique in terms of hospital stay and post-ERCP hyperamylasemia.

Although the existing data link specific S100 proteins with IBD, there are still several drawbacks in the use of these markers for diagnostic purposes. Thus, it seems that further research is mandatory in order to eliminate the impact of confounding factors but also to detect additional associations between S100 proteins and IBD or novel S100 proteins with a closer correlation with IBD.
