Microbioma materno-infantilaplicación al distrés posparto y alteraciones gastrointestinales y respiratorias infantiles

Résumé

Human milk contains numerous nutrients, bioactive compounds and commensal bacteria that have an important influence on infant health. Among all the bioactive components present in human milk, the microbiota and the immunological composition have great relevance since they actively determine the growth and maturation of numerous organs and tissues, protect against pathogens and contribute to the normal colonization of the gastrointestinal tract. In the gut colonization of the infant, which increases dramatically after birth, the mammary microbiota plays a special role, providing a constant supply of bacteria to the newborn through lactation. Therefore, any factor that influences the milk composition can have a direct reflection on the infant health. The composition of human milk has been the subject of several studies that have shown its great inter-individual variability as well as its variation with various maternal and environmental factors. However, there is no information on the influence that maternal postnatal psychosocial distress could have on milk composition...
