Frailty is increasingly becoming an important public health challenge worldwide because it is associated with older age, and with adverse outcomes such as reduced quality of life, increased mortality rates, hospitalizations, falls, depression, and dementia. Frailty is defined as dynamic state affecting an individual who experiences losses in one or more domains of human functioning (physical, psychological, social) that are caused by the influence of a range of variables, and which increases the risk of adverse outcomes. This more integral conceptual definition promotes the collaboration of scientists, social and behavioral professionals as well as clinicians from diverse specialties. In this proposal an interdisciplinary group (Biochemistry, Geriatric, Occupational Therapist, Kinesiologist, social worker, bioengineer, statistician among others) aims to evaluate frailty in Chile with a biopsychosocial approach with the final purpose to identify and manage frailty while taking into consideration all the dimensions. Additionally, we aim to design a multidomain personalized person-base intervention for a healthy aging that can uncover a circulating microRNA biomarker panel that can allow an early-detection of frailty, leading to a new multidimensional geriatric assessment. We propose the following hypothesis: A personalized multidimensional training program reduces the frailty prevalence, increasing adherence and participation in the program among community-living older adults. This intervention will be paralleled by a distinctive miRNA profile reflecting the multiple domains of frailty, as well as improvements in diverse psychosocial traits.

EPIGENOMIC PROGRAMMING IN THE EARLY FETAL BLOOD-BRAIN BARRIER BY GESTATIONAL HYPOXIA: CONSEQUENCES FOR THE NEURO-ENDOTHELIAL LIFESPAN.

The proposal focuses on understanding the neuro-vascular aging mechanisms associated with alterations in fetal growth by intrauterine hypoxia using molecular biology and physiology as an area. The aim of the study is to demonstrate that impaired fetal growth conditions are associated with epigenetic programming of aging-related DNA methylation, chromatin remodeling, and miRNA-omic profile of junctional complex genes in the neuroendothelium, which can alter BBB integrity and permeability, increasing cerebral damage which impacts the juvenile and adulthood neurocognitive function.

EPIGENOMIC PROGRAMMING IN THE EARLY FETAL BLOOD-BRAIN BARRIER BY GESTATIONAL HYPOXIA: CONSEQUENCES FOR THE NEURO-ENDOTHELIAL LIFESPAN.

Los tiempos actuales han facilitado nuevos medios de expresión e interacción como son las redes sociales. Estas plataformas, desde unos orígenes que bien podrían definirse como centrados en el entretenimiento, la comunicación interpersonal y la puesta en común de nuestra imagen e intereses, han pasado a convertirse en arenas de debates polarizados y nada edificantes. En este escenario, nos parece necesario preguntarnos: ¿cómo funciona la producción y circulación cross-plataforma de discursos de odio en las redes sociales chilenas en los últimos años? Para obtener una respuesta, confiamos en que una aproximación interdisciplinar emprendida por un equipo de comunicadores, lingüistas y cientistas de datos puede proporcionar una mirada más completa y compleja sobre este problema. Nuestro objetivo general es comprender el funcionamiento cross-plataforma de los discursos de odio producidos y puestos en circulación en las redes sociales en Chile a partir de las tendencias informativas más relevantes entre 2015 y 2023. Para ello requerimos: 1) caracterizar cuantitativa y cualitativamente los tipos de discursos de odio producidos y puestos en circulación en las redes sociales en Chile a partir de las tendencias informativas más relevantes entre 2015 y 2023; 2) identificar las cuentas de origen y diseminación que hacen posible tanto la producción como la circulación cross-plataforma de los tipos de discursos de odio y sus comentarios en las redes sociales en Chile, y; 3) analizar cualitativamente las estrategias lingüísticas y semióticas usadas sistemáticamente en la producción de los tipos de discursos de odio y sus comentarios. Además, y no menos importante, proponemos diseñar un kit de recursos digitales con ejemplos y recomendaciones para fomentar estrategias de formación ciudadana que ayuden a los/as usuarios/as de estas redes sociales a leer críticamente los discursos de odio y proyectar acciones para confrontarlos o neutralizarlos. Si bien esta es una acción de divulgación científica, nos parece necesario dar un pequeño paso que proyecte incluso futuras investigaciones aplicadas.
