This section covers basic topics and illustrates the technical notion of a computational effect with several mathematical and programming examples. In everyday language, a “side effect” refers to the unintended or unforeseen consequences of an action. By analogy, in order to identify the side effect of a given computation, it is first necessary to isolate the “publicly stated” or “publicly expe...

UNLABELLED Cognitive side-effects such as emergence agitation (EA), postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are not infrequently complicating the postoperative care especially in elderly and fragile patients. The aim of the present survey was to gain insight regarding concern and interest in prevention and treatment strategies for postoperative delirium and d...

In coronary artery disease, cardiovascular risk factors are the main targets for primary and secondary prevention. Statins prevent cardiovascular events in patients at risk. However, despite the proven efficacy and safety of statins, relevant side effects exist and should be considered when treating patients.

Low-dose aspirin is widely used in the primary and secondary prevention of cardiovascular events, but is associated with a range of upper gastrointestinal side effects. In this review, we summarize the rationale for low-dose aspirin therapy, quantify the risk for upper gastrointestinal side effects, identify the risk factors involved, and provide an overview of preventive strategies, thereby fo...

The amount of transfused dimethyl sulfoxide (DMSO) is indicated as the major cause of the cryoprotectant-related toxicity in autologous stem cell recipients, with a high incidence of major cardiac side effects. In this study we tried to discover whether fractionated infusion of the total graft volume could prevent the DMSO-related major cardiovascular side effects. We conclude that continuous c...

Hydrogen sulfide (H(2)S) is now recognized as an important signaling molecule and has been shown to have vasodilator and cardio-protectant effects. More recently it has been suggested that H(2)S may also act within the brain to reduce blood pressure (BP). In the present study we have demonstrated the presence of the H(2)S-producing enzyme, cystathionine-β-synthase (CBS) in the rostral ventrolat...
