The SARS-CoV-2 pandemic has evolved far more aggressively in countries lacking a robust testing strategy to identify infected individuals. Given the global demand for fast and reliable diagnosis to determine the carrier individuals, a stock-out scenario for a number of essential reagents/kits used along the diagnostic process has been foreseen by many organizations. Having identified the RNA extraction step as one of the key
Actualmente, sólo una pequeña proporción de enfermedades crónicas son explicadas por factores genéticos. Aunque el conocimiento acerca de la exposición ambiental es importante para determinar el origen de algunas enfermedades crónicas, éste aún es impreciso. La investigación en humanos en este tema se ha centrado, principalmente, en los efectos de una determinada exposición acerca de la salud. El concepto de "exposoma" abarca la totalidad de las exposiciones desde la concepción en adelante, complementando al genoma. La infancia temprana es una etapa de la vida particularmente vulnerable a la exposición ambiental. El exposoma gastrointestinal representa el conjunto de compuestos xenobióticos que afectan la función digestiva del huésped. Por lo tanto, una mejor comprensión de la interacción entre el microbioma y el exposoma gastrointestinal proporcionaría nuevas perspectivas de intervención clínica, a través de la regulación de los sistemas inmunológico, metabólico o neuroendocrino asociados con el intestino. Esta revisión de la bibliografía se enfoca en lo que representa el exposoma, su constructo teórico, importancia, características y la influencia de éste en los primeros mil días de vida y la salud gastrointestinal. Se revisaron 70 referencias bibliográficas, sobre todo artículos publicados en revistas académicas en relación con este tema a partir del año 2000 hasta la actualidad.PALABRAS CLAVE: exposoma, primeros días de vida, exposoma gastrointestinal, microbiota, inmunidad gastrointestinal e inflamación, xenobiótico. Abstract It is world widely accepted that a relatively small proportion of chronic disease can be explained by genetic factors alone. Although information about environmental exposure is important to comprehensively evaluate chronic diseases, this information is not sufficiently or accurately assessed by comparison with genomic factors. Human research on this topic has generally focused on single exposure health effect relationships. The “exposome” concept encompasses the totality of exposures from conception onward, complementing the genome. Developmental periods in early life may be particularly vulnerable to impacts of environmental exposures. The gastrointestinal exposome represents the integration of all xenobiotic components affecting the host health, disease progression and ultimately clinical outcomes during the lifespan. Therefore, a better understanding the interaction between microbiome and the gastrointestinal exposome would provide new insights into the clinical intervention, through regulation of the gut-associated immunological, metabolic, or neuroendocrine system. This review of the literature focuses on exposome, its theoretical construct, importance, characteristics and influence in the first 1000 days old and gastrointestinal health. It was revised 70 bibliography references, especially articles published in academic journals, related to this subject from the year 2000 to present.KEYWORDS: Exposome; Early-life; Gastrointestinal exposome; Microbiota; Gastrointestinal immunity and inflammation; Xenobiotic
Este año el Instituto Nacional de Pediatría al contar con su Repositorio Institucional, se consolida como el primer Instituto Nacional de Salud con una plataforma digital en la que se preserva, almacena y archiva, de acuerdo con estándares internacionales, toda la producción de la investigación científica.
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.
