“…Silva-López M. 1,2,a , Hernandez-Patiño I. 1,2,b Sr. Editor Dos décadas atrás Baker dio el concepto de Programación Fetal (PF), donde asociaba el ambiente prenatal y el desarrollo del feto (1) . En consecuencia, la PF representaría "la inducción de las respuestas fetales debido al entorno uterino" que condicionará cambios funcionales y estructurales en el propio feto, con repercusión a corto y largo plazo (2) .…”

“…Teniendo como desenlace que el cortisol pase a la circulación fetal con las debidas consecuencias (5) . esto se verá evidenciado con alteraciones en la homeostasis del feto desde el aumento de riesgo de abortos espontáneos, menor peso al nacer y parto prematuro e incluso hasta la desregulación del eje Hipotálamo Hipófisis Adrenal del feto (1) .…”

“…It is known that in the neonatal period, which is fundamental for the development of the nervous system, fetal reprogramming may occur due to stressors (physical, nutritional, hormonal and exogenous, in the form of drugs), which may leave the neonate prone to behavioral changes, alterations in memory and psychomotor development, as well as personality, cognitive, anxiety and psychotic disorders in childhood and adulthood. 30,31 Among the main structures affected in the neonate due to this factor are: HPA axis, glutamatergic, serotonergic and GABAergic systems, structures (prefrontal, temporal and insular cortex), subcortical structures (amygdala and hippocampus), cerebellum and placenta. Studies on maternal stress during pregnancy corroborate the idea that stress in this phase may act as a teratogen agent, primarily in the early stages of pregnancy.…”

“…The consequences of this factor can range from a simple reduction in the level of uterine sites for implantation of the blastocyst to prematurity, low birth weight and abortion. 31 With the implementation of neonatal intensive care units, the survival of preterm infants has increased considerably. In addition, environments in which babies are subjected to constant lighting and procedures perceived as painful, as well as instability of body temperature, weight loss and stress, have provided a research front regarding the quality of sleep in babies and their future considerations.…”

The search for articles was conducted in January 2020 in six databases: Academic Google, PubMed, SciElo, Cochrane Library, Scopus and Web of Science. The keywords used in all databases were: "subplate neurons", "newborn or neonate and subplate neuron", "neurodevelopment disorder and subplate neurons", "cognition and subplate neurons", "stress and subplate neurons", "pain or nociception and subplate neurons", "Autism and subplate neurons", "Schizophrenia and subplate neurons". Each combination corresponded to an individual query. Keywords had to appear in the title or abstract. No restrictions were placed on language or year of publication. The inclusion criteria for this review covered original articles and review articles explaining the formation, functions, and changes related to the SPN. Exclusion criteria were studies that did not address SPN and cognition, neurodevelopmental disorder, mental retardation, autism, pain, nociception, schizophrenia or stress. Thus, 566 of the 623 previously chosen articles were excluded (Figure 1) mainly for reasons as animal study, only physiologic analyses, not newborn infant or other reasons as oral/poster presentation only. Reporting of the results followed the Preferred Reporting Items of Systematic reviews and Meta-Analyses (PRISMA) statement of 2009.

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. RESUMEN Introducción: Desde el momento de la concepción el ser humano está predispuesto a sufrir cambios en el desarrollo fetal y neonatal debido a diversos factores externos que se presentan a lo largo de la vida y pueden a largo plazo influir en la expresión fenotípica del nuevo ser. 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. Palabras clave: desarrollo neonatal, epigenética, microbiota, desarrollo fetal, nutrición.
