Correlation of Environment, Nutrition, Genetics, Epigenetics, Microbiota with Neonatal Fetus Development


Introduction: From the moment of conception the human being is predisposed to undergo changes in fetal and neonatal development due to various external factors that occur throughout life and can in the long term influence the phenotypic expression of the new being. Objective: The objective of this work is to determine the relationship between the environment, nutrition, genetics, epigenetics and microbiota with neonatal fetus development and how they influence the phenotypic expression of the new being. Methods: A non-systematic search was performed in electronic databases such as COCHRANE, PUBMED, MEDLINE, etc. The bibliographic research was carried out in the period between October 2019 and January 2020. The studies carried out from 2007 to 2019, in the languages of Spanish and English, were included. Results: We found 51 bibliographic sources related to the subject, of which by means of a last simplification, 30 scientific articles were used that provided important information on the subject, and 21 articles were excluded. Conclusion: Research on methods to detect these interactions and to understand the mechanisms of these interactions is just beginning. However, there is evidence that they play an important role in human development.

Keywords: neonatal development, epigenetics, microbiota, fetal development, nutrition.

Objetivo: El objetivo del presente trabajo es determinar la relación que existe entre el medio ambiente, nutrición, genética, epigenética y microbiota con el desarrollo feto neonatal y como los mismos influyen en la expresión fenotípica del nuevo ser. Métodos: Se realizó una búsqueda no sistemática en bases de datos electrónicas como COCHRANE, PUBMED, MEDLINE, etc. La investigación bibliográfica se realizó en el periodo comprendido entre octubre 2019 y enero 2020. Se incluyeron estudios realizados desde el año 2007 hasta el año 2019, en los idiomas de español e inglés. Resultados: Se encontraron 51 fuentes bibliográficas referentes al tema, de los cuales mediante una última simplificación se utilizaron 30 artículos científicos que aportaron información importante del tema y se excluyeron 21 artículos. Conclusiones: La investigación sobre métodos para detectar estas interacciones y para comprender los mecanismos de estas interacciones apenas está comenzando. Sin embargo, hay evidencia de que estas juegan un papel importante en el desarrollo humano.
