    INTRODUCCIÓN El colecho, es una prĂĄctica que se ha llevado a cabo durante siglos. Son muchas las familias que lo han practicado y practican aĂșn hoy en dĂ­a sin saberlo. Años atrĂĄs, era algo muy comĂșn y con el paso del tiempo ha ido generando controversia creando partidarios y detractores. OBJETIVO Realizar una revisiĂłn bibliogrĂĄfica que identifique las ventajas, los inconvenientes, su relaciĂłn con la lactancia materna y los consejos para llevar una buena prĂĄctica. METODOLOGÍA Se ha realizado una bĂșsqueda en diferentes bases de datos, revistas cientĂ­ficas y pĂĄginas web. Empleando los siguientes descriptores: “Colecho”, “BebĂ©â€, “Beneficios”, “Ventajas”, “Inconvenientes”, “SĂ­ndrome Muerte SĂșbita del Lactante”, “Lactancia materna”, “Puerperio”. Todos los artĂ­culos incluidos, datan de 2009 a 2019. DESARROLLO El colecho cuenta con mĂșltiples beneficios para el bebĂ©, pese a ser un factor relacionado con el SĂ­ndrome de Muerte SĂșbita del Lactante lo cual provoca controversia. CONCLUSIONES La prĂĄctica del colecho, es un claro factor positivo para el mantenimiento de la lactancia materna. Y no existe evidencia suficiente para relacionarlo con el SĂ­ndrome de Muerte SĂșbita del Lactante. PALABRAS CLAVE “Colecho”, “BebĂ©â€, “Beneficios”, “Ventajas”, “Inconvenientes”, “SĂ­ndrome Muerte SĂșbita del Lactante”, “Lactancia materna”, “Puerperio”.<br /

    Sera from Patients with NMOSD Reduce the Differentiation Capacity of Precursor Cells in the Central Nervous System

    Introduction: AQP4 (aquaporin-4)–immunoglobulin G (IgG)-mediated neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating disease that affects the central nervous system, particularly the spinal cord and optic nerve; remyelination capacity in neuromyelitis optica is yet to be determined, as is the role of AQP4–IgG in cell differentiation. Material and Methods: We included three groups—a group of patients with AQP4–IgG-positive neuromyelitis optica, a healthy group, and a sham group. We analyzed differentiation capacity in cultures of neurospheres from the subventricular zone of mice by adding serum at two different times: early and advanced stages of differentiation. We also analyzed differentiation into different cell lines. Results and Conclusions: The effect of sera from patients with NMOSD on precursor cells differs according to the degree of differentiation, and probably affects oligodendrocyte progenitor cells from NG2 cells to a lesser extent than cells from the subventricular zone; however, the resulting oligodendrocytes may be compromised in terms of maturation and possibly limited in their ability to generate myelin. Furthermore, these cells decrease in number with age. It is very unlikely that the use of drugs favoring the migration and differentiation of oligodendrocyte progenitor cells in multiple sclerosis would be effective in the context of neuromyelitis optica, but cell therapy with oligodendrocyte progenitor cells seems to be a potential alternative
