Clinical and Neurobiological Perspectives of Empowering Pediatric Cancer Patients Using Videogames.

Pediatric oncology patients often experience fatigue and physical and mental deconditioning during and following chemotherapy treatments, contributing to diminished quality of life. Patient empowerment is a core principle of patient-centered care and reflects one's ability to positively affect his or her own health behavior and health status. Empowerment interventions may enhance patients' internal locus of control, resilience, coping skills, and self-management of symptoms related to disease and therapy.

Genetic chimeras reveal the autonomy requirements for Vsx2 in embryonic retinal progenitor cells.

Background: Vertebrate retinal development is a complex process, requiring the specification and maintenance of retinal identity, proliferative expansion of retinal progenitor cells (RPCs), and their differentiation into retinal neurons and glia. The homeobox gene Vsx2 is expressed in RPCs and required for the proper execution of this retinal program. However, our understanding of the mechanisms by which Vsx2 does this is still rudimentary.

Patient-empowerment interactive technologies.

Video games capture the rapt attention of an individual player's mind and body, providing new opportunities for personalized health care. An example of therapeutic interactive technologies is an incentive-based video game that translates physical exercise into mental empowerment via motivational metaphoric visualization in order to help patients psychologically overcome cancer. Such nonpharmacological interventions may enhance patients' resilience toward various chronic disorders via neuronal mechanisms that activate positive emotions and the reward system.
