Will high-sensitive troponin immunoassays lead to more clarity or confusion in clinical practice?

Although increases in cTnI (cardiac troponin I) and cTnT (cardiac troponin T) always indicate myocardial damage, the test is not able to identify the mechanisms responsible for this damage, which may not be due to ischaemia, but rather to other clinical conditions. In the present issue of Clinical Science, Filusch and co-workers have assessed cTnT using a high-sensitive assay in patients with p...

Clarity from Confusion: Using Intended Interactions to Design Information Systems

Two tools are described that help designers visualize the structure of a system in the requirements phase of a project. First, a matrix is constructed that represents the tendency of components to interact. The matrix is derived from sequence diagrams, which in turn are based on textual scenarios. This interaction matrix is transformed into a structure plot of the system, showing a graph of the...
