This paper analyses one of the most well-known general purpose adaptive hypermedia systems, AHA!, and, based on this analysis, make some general observations about adaptive hypermedia systems and some improvement suggestions for the AHA! system. We suggest here a concept-based approach to the structuring of adaptive hypermedia systems, as well as an extension of the well-known rule-based overla...

Infective endocarditis is a rare but life-threatening microbial infection of the heart valves or endocardium, most often related to congenital or acquired cardiac defects. The American Heart Association (AHA) recently updated its recommendations on prophylaxis during dental procedures. The revisions will have a profound impact on both the patient and the dental practitioner. The purpose of this...

The growing use of digital platforms among older adults has brought increased challenges to the design and development process, thus requiring considering age-related needs changes. Nonetheless, a body research suggests that different types applications platforms, i.e., games, can foster new opportunities encourage active healthy ageing (AHA) by promoting knowledge acquisition, developing compe...

An 'Aha! reaction' is a brief moment of exceptional thinking where an unexpected change in one's mental perspective reveals the solution to an otherwise intractable problem. In this event-related fMRI study, subjects read incomprehensible sentences followed by solution cues that were used to evoke such a reaction by triggering an alternative interpretation of the critical concepts. For 73% of t...

A recent Science Advisory from the American Heart Association (AHA) recommended routine screening of all patients with coronary heart disease (CHD) for depression. The authors of the advisory noted that the high prevalence of depression in patients with CHD supports this strategy. A systematic review of the evidence on depression screening and treatment in CHD patients published soon after the ...

In this work we present a tool for Adaptive Support for Collaborative and Individual Learning (ASCIL). Taking as a base the fact that learning is not solely an individual nor collaborative process, we have come to the conclusion that it is an integrated activity which requires integral support. We have therefore applied two previously developed systems, AHA! and CLAROLINE, which we have integra...

BACKGROUND Little is known about statin underutilization among diabetes mellitus patients cared for in community health centers, which tend to serve socioeconomically disadvantaged populations. Implications of the American College of Cardiology/American Heart Association (ACC/AHA) guidelines on preexisting gaps in statin treatment in this population are unclear. METHODS AND RESULTS We include...
