The role of mobile technologies in health care processes:The case of cancer supportive care

Background: Health care systems are gradually moving towards new models of care based on integrated care processes, shared by different care givers, and on an empowered role of the patient. Mobile technologies are assuming an emerging role in this scenario. This is particularly true in care processes where the patient has a particularly enhanced role, as is the case of cancer supportive care. Objective: This paper aims to review existing studies on the actual role and use of mobile technology during the different stages of care processes, with particular reference to cancer supportive care. Methods: We carried out a review of literature with the aim of identifying studies related to the use of mhealth in cancer care and cancer supportive care. The final sample size consists in 106 records. Results: There is scant literature concerning the use of mhealth in cancer supportive care. Looking more generally at cancer care, we found that mhealth is mainly used for self management activities carried out by patients. The main tools used are mobile devices like smartphones and tablets, but remote monitoring devices also play an important role. SMS technologies have a minor role with the exception of middle income-countries where SMS plays a major role. Tele-health technologies are still rarely used in cancer care processes. If we look at the different stages of health care processes, we can see that mhealth is mainly used during the treatment of patients, especially for self management activities. It is also used for prevention and diagnosis, although to a lesser extent, whereas it appears rarely used for decision-making and follow-up activities. Conclusions: Since mhealth only seems to be employed for limited uses and during limited phases of the care process, it is unlikely that it can really contribute to the creation of new care models. This under-utilization may depend on many issues, including the need for it to be embedded into broader information systems. If the purpose of introducing mhealth is to promote the adoption of integrated care models, using mhealth should not be limited to some activities or to some phases of the health care process. Instead, there should be a higher degree of pervasiveness at all stages and in all health care delivery activities

The macrophage in HIV-1 infection: From activation to deactivation?

Macrophages play a crucial role in innate and adaptative immunity in response to microorganisms and are an important cellular target during HIV-1 infection. Recently, the heterogeneity of the macrophage population has been highlighted. Classically activated or type 1 macrophages (M1) induced in particular by IFN-γ display a pro-inflammatory profile. The alternatively activated or type 2 macrophages (M2) induced by Th-2 cytokines, such as IL-4 and IL-13 express anti-inflammatory and tissue repair properties. Finally IL-10 has been described as the prototypic cytokine involved in the deactivation of macrophages (dM). Since the capacity of macrophages to support productive HIV-1 infection is known to be modulated by cytokines, this review shows how modulation of macrophage activation by cytokines impacts the capacity to support productive HIV-1 infection. Based on the activation status of macrophages we propose a model starting with M1 classically activated macrophages with accelerated formation of viral reservoirs in a context of Th1 and proinflammatory cytokines. Then IL-4/IL-13 alternatively activated M2 macrophages will enter into the game that will stop the expansion of the HIV-1 reservoir. Finally IL-10 deactivation of macrophages will lead to immune failure observed at the very late stages of the HIV-1 disease
