A general protocol for rigorous evaluation of diagnostic systems in medicine was applied successfully in a comparative study of two radiologic techniques. Accuracies of computed tomography and radionuclide scanning in detecting, localizing, and diagnosing brain lesions were assessed with a sample of patients in whom tumor had been suspected. The principal(More)
BACKGROUND Hospital transfusion laboratories collect information regarding blood transfusion and some registries gather clinical outcomes data without transfusion information, providing an opportunity to integrate these two sources to explore effects of transfusion on clinical outcomes. However, the use of laboratory information system (LIS) data for this(More)
Our goal is to improve patient outcomes and safety through medical device interoperability. To achieve this, it is not enough to build a technically perfect system. We present here our work toward the validation of middleware for use in interoperable medical cyber-physical systems. This includes clinical requirements, together with our methodology for(More)
In colonic adenocarcinomata abnormalities have been noted in all morphological aspects of the local immune system of the bowel; thus, in such tumours there is a defective production of secretory IgA, a diminished content of secretory component (SC) and a marked decrease in intraepithelial lymphocytes. By contrast, no such abnormalities were noted in the(More)
