ReviewBeyond futility: to what extent is the concept of futility useful in clinical decision-making about CPR?
The concept of futility has often been invoked to justify abstention from treatment and decisions such as 'do not attempt resuscitation' (DNAR). In this capacity, futility has played an important part in the development of several sets of official clinical guidelines. ⋯ Although the concept of futility promises simplicity, it cannot stand alone as a satisfactory framework for clinical decision-making. Practitioners and policy makers should be cautious about their use of the concept.

Hyperthermia, the procedure of raising the temperature of tumour-loaded tissue to 40-43 degrees C, is applied as an adjunctive therapy with various established cancer treatments such as radiotherapy and chemotherapy. The potential to control power distributions in vivo has been significantly improved lately by the development of planning systems and other modelling tools. This increased understanding has led to the design of multiantenna applicators (including their transforming networks) and implementation of systems for monitoring of E-fields (eg, electro-optical sensors) and temperature (particularly, on-line magnetic resonance tomography). ⋯ Therefore, further development of existing technology and elucidation of molecular mechanisms are justified. In recent molecular and biological investigations there have been novel applications such as gene therapy or immunotherapy (vaccination) with temperature acting as an enhancer, to trigger or to switch mechanisms on and off. However, for every particular temperature-dependent interaction exploited for clinical purposes, sophisticated control of temperature, spatially as well as temporally, in deep body regions will further improve the potential.
