ABSTRACT
Background: The Program "Más Adultos Mayores Autovalentes" (Más AMA) started in 2015 as a strategy for the prevention of disability among older adults. Aim: To describe the health benefits, from user's perspective, of the Functional Stimulation Component of the Más AMA program. Material and Methods: Eleven focus groups including 97 participants of the Más AMA program were conducted in Northern Metropolitan Santiago municipalities. Results: The benefits perceived by Más AMA participants were a reduction in loneliness and isolation, physical reactivation, engagement in activities, and the use of support resources within the community. The relationship with professionals working at Más AMA was described as highly satisfactory. Conclusions: The benefits of attending the Más AMA program from the point of view of their users are mainly related with social and affective dimensions, which contrast with the emphasis in physical and cognitive dimensions given by the technical orientation of the Más AMA program.

En la actualidad existe consenso en que el daño de los tejidos de soporte dentario que se produce durante la periodontitis es un proceso complejo en el cual la presencia de los patógenos periodontales es necesaria, pero no suficiente, para explicar en su totalidad la extensión y severidad de dicho daño. Asimismo, la destrucción del tejido de soporte periodontal es en gran medida producida por el desbalance de la respuesta inmune generada por el paciente frente a antígenos y factores de virulencia derivados de los patógenos periodontales. Esta respuesta inmune, desencadenada por las bacterias periodontopatógenas, incluye tanto mecanismos asociados a inmunidad innata como adaptativa, siendo el rol de los péptidos antimicrobianos y mediadores lipídicos aspectos relacionados con ambas ramas de la inmunidad y que no han sido completamente dilucidados en relación con sus mecanismos de acción contra los patógenos periodontales. En esta revisión se describe el rol de los péptidos antimicrobianos y de los mediadores lipídicos en la enfermedad periodontal, enfocándonos en su contribución tanto a la protección como a la destrucción del tejido de soporte dentario durante la infección periodontal. Se destaca además la importancia de considerarlos dentro del complejo escenario de la respuesta inmune durante las enfermedades periodontales, ya que forman parte fundamental de la respuesta inmune del hospedero. Analizar la enfermedad periodontal ampliando la perspectiva de estudio a este tipo de moléculas que participan de la respuesta inmune permitiría en el futuro lograr un nuevo enfoque terapéutico de las enfermedades periodontales.
Currently, there is consensus that the damage of the tooth support tissues that occurs during periodontitis is a complex mechanism, in which the presence of specific periodontal pathogens is necessary, but not sufficient, to fully explain the extent and severity of the observed periodontal destruction. Moreover, the destruction of periodontal support tissue is largely the effect of the imbalance in the patient immune response, triggered by periodontal pathogen-derived antigens and virulence factors. The immune response elicited by periodontal pathogenic bacteria includes mechanisms associated with both innate and adaptive responses, where the role of antimicrobial peptides and lipid mediators are related to these two arms of immunity, and have not been fully elucidated in relation to their mechanisms of action against periodontal pathogens. In this review, a discussion is presented on the characteristics of these molecules and their role in periodontal disease in relation to both protection and destruction of tooth supporting tissue during periodontal infection. The relevance of considering these mediators within the complex scenario of the immune response during periodontal diseases is also highlighted, since they are a fundamental part of the host immune response. Periodontal diseases should be analysed in a broader perspective, where the study of these types of molecules involved in the immune response of periodontal tissues, may help to develop new therapeutic approaches to periodontal diseases in the future.
