[Epigenetics and oncology: Two faces of the personalization of medicine]. / Épigénétique et cancérologie - Deux visages de la personnalisation de la médecine.

In this article, we outline the two dominant concepts of personalized medicine put forward by epigenetics in the field of oncology. First, knowledge on the molecular processes involved in tumor progression contributes to molecularize medicine, extending genomic medicine. Then, the identification of epigenetic mechanisms underlying the environmental causes of cancers brings scientific legitimacy to products and services whose advertising promotes the ability of each person to protect herself from cancer by adapting her lifestyle. Lastly, we argue that research in environmental epigenetics could open a new route for personalized medicine in oncology, where epigenetics contributes to an individualized assessment of patients' life paths.

Title: Épigénétique et cancérologie - Deux visages de la personnalisation de la médecine. Abstract: Deux conceptions distinctes de la médecine personnalisée en cancérologie accompagnent le développement de la recherche en épigénétique : l'étude des processus moléculaires associés à la progression tumorale, qui renforce, dans l'espace médical, le programme de molécularisation de la médecine génomique ; l'exploration des mécanismes épigénétiques sous-jacents aux causes environnementales des cancers, qui apporte, dans la sphère marchande, une légitimité scientifique à des produits et à des services dont le marketing prône la capacité de chacun à se protéger du cancer par un style de vie adapté. La recherche en épigénétique environnementale pourrait, quant à elle, ouvrir une troisième voie pour la médecine personnalisée, centrée sur une approche individualisée des parcours de vie.

Attitudes of General Practitioners Toward Prescription of Mobile Health Apps: Qualitative Study.

BACKGROUND: Mobile health (mHealth) apps are a potential means of empowering patients, especially in the case of multimorbidity, which complicates patients' care needs. Previous studies have shown that general practitioners (GPs) have both expectations and concerns regarding patients' use of mHealth apps that could impact their willingness to recommend the apps to patients. OBJECTIVE: The aim of this qualitative study is to investigate French GPs' attitudes toward the prescription of mHealth apps or devices aimed toward patients by analyzing GPs' perceptions and expectations of mHealth technologies. METHODS: A total of 36 GPs were interviewed individually (n=20) or in a discussion group (n=16). All participants were in private practice. A qualitative analysis of each interview and focus group was conducted using grounded theory analysis. RESULTS: Considering the value assigned to mHealth apps by participants and their willingness or resistance to prescribe them, 3 groups were defined based on the attitudes or positions adopted by GPs: digital engagement (favorable attitude; mHealth apps are perceived as additional resources and complementary tools that facilitate the medical work, the follow-up care, and the monitoring of patients; and apps increase patients' compliance and empowerment); patient protection (related to the management of patient care and fear of risks for patients, concerns about patient data privacy and security, doubt about the usefulness for empowering patients, standardization of the medical decision process, overmedicalization, risks for individual freedom, and increasing social inequalities in health); doctor protection (fear of additional tasks and burden, doubt about the actionability of patient-gathered health data, risk for medical liability, dehumanization of the patient-doctor relationship, fear of increased drug prescription, and commodification of patient data). CONCLUSIONS: A deep understanding of both the expectations and fears of GPs is essential to motivate them to recommend mHealth apps to their patients. The results of this study show the need to provide appropriate education and training to enhance GPs' digital skills. Certification of the apps by an independent authority should be encouraged to reassure physicians about ethical and data security issues. Our results highlight the need to overcome technical issues such as interoperability between data collection and medical records to limit the disruption of medical work because of data flow.

Patients' Perceptions of mHealth Apps: Meta-Ethnographic Review of Qualitative Studies.

BACKGROUND: Mobile phones and tablets are being increasingly integrated into the daily lives of many people worldwide. Mobile health (mHealth) apps have promising possibilities for optimizing health systems, improving care and health, and reducing health disparities. However, health care apps often seem to be underused after being downloaded. OBJECTIVE: The aim of this paper is to reach a better understanding of people's perceptions, beliefs, and experience of mHealth apps as well as to determine how highly they appreciate these tools. METHODS: A systematic review was carried out on qualitative studies published in English, on patients' perception of mHealth apps between January 2013 and June 2018. Data extracted from these articles were synthesized using a meta-ethnographic approach and an interpretative method. RESULTS: A total of 356 articles were selected for screening, and 43 of them met the inclusion criteria. Most of the articles included populations inhabiting developed countries and were published during the last 2 years, and most of the apps on which they focused were designed to help patients with chronic diseases. In this review, we present the strengths and weaknesses of using mHealth apps from the patients' point of view. The strengths can be categorized into two main aspects: engaging patients in their own health care and increasing patient empowerment. The weaknesses pointed out by the participants focus on four main topics: trustworthiness, appropriateness, personalization, and accessibility of these tools. CONCLUSIONS: Although many of the patients included in the studies reviewed considered mHealth apps as a useful complementary tool, some major problems arise in their optimal use, including the need for more closely tailored designs, the cost of these apps, the validity of the information delivered, and security and privacy issues. Many of these issues could be resolved with more support from health providers. In addition, it would be worth developing standards to ensure that these apps provide patients accurate evidence-based information.
