The World Health Organization (WHO) defines health not only as the absence of disease but as a state of complete physical, mental and social well-being. Gratitude is one of the concepts most commonly associated with well-being from the empirical point of view. Despite of this, we seldom use the concept, possibly due to the lack of dissemination of its scientific bases and possible clinical applications. At an anatomical level, it is related consistently with the medial prefrontal cortex and at molecular level, with the neuropeptide oxytocin. It has been associated with better physical and mental health parameters, both in healthy and sick populations. It is usually measured using scales, being the most used worldwide the Gratitude Questionnaire-6 item . There are exercises that can enhance gratitude and its benefits, such as the gratitude letter and the gratitude journal. Given the current state of knowledge about gratitude, and considering its potential benefits, low risks, ability to complement other treatments, the simple and cost-effectiveness of gratitude interventions, a continuing research on this topic and its practical implementation is warranted.

An appraisal of healthcare mobile applicationsMobile applications (Apps) may become effective aids in health care. Health Apps could reduce barriers such as access and costs and could be used to monitor symptoms, behaviors and even treatments. There is more evidence of their usefulness in nutrition, cardiovascular and mental health. Despite this, its current use is predominantly for information purposes. Healthcare App quality evaluation should consider both clinical and technological aspects since the evidence on its clinical effectiveness is still incipient and they have associated risks. In Chile, the use of mobile technology and Apps is increasing, but there are no regulations for their use. There are few national institutions oriented to the creation and development of Apps for healthcare, highlighting the Digital Transformation Committee, part of the Corporation for the Promotion of Production (CORFO) and the National Center for Health Information Systems (CENS). General recommendations for healthcare App development and use have been established. In this process, it would be beneficial to include actors involved in care. Given the progress of healthcare Apps worldwide and nationally, it is important that health professionals develop digital skills to maximize the potential benefit of these technologies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
