Vitamina D y la lactancia humana
Lancet (London, England)
|October 8, 1977
Resumen
Las madres lactantes muestran niveles séricos más altos de vitamina D que las madres no lactantes. La lactancia en sí misma no alteró significativamente los niveles de vitamina D, lo que sugiere que no hay necesidad de suplementos de vitamina D durante la lactancia materna.
Área de la Ciencia:
- La bioquímica nutricional es una bioquímica nutricional.
- Salud materna y infantil.
Sus antecedentes:
- La vitamina D es crucial para la salud ósea y la función inmune.
- El estado materno de la vitamina D puede afectar tanto a la madre como al bebé.
- Comprender la dinámica de la vitamina D durante la lactancia es importante para la nutrición infantil.
Objetivo del estudio:
- Para comparar las concentraciones séricas de 25-hidroxivitamina D en las madres lactantes frente a las no lactantes.
- Para evaluar el impacto de la duración de la lactancia (4-6 semanas) en los niveles de vitamina D.
- Para determinar si la lactancia requiere suplementos de vitamina D.
Principales métodos:
- Medición de la 25-hidroxivitamina D circulante en el suero.
- Comparación entre las madres recién nacidas que estaban amamantando y las que no lo estaban.
- Evaluación al inicio y después de 4-6 semanas de lactancia.
Principales resultados:
- Las madres que amamantan exhibieron significativamente mayores niveles basales séricos de 25-hidroxivitamina D en comparación con las madres que no amamantan.
- Los niveles séricos de 25-hidroxivitamina D no cambiaron significativamente entre el inicio y 4-6 semanas después del parto en el grupo de lactancia materna.
- No se observaron diferencias significativas en los niveles de vitamina D entre las 4-6 semanas y las mediciones basales dentro del grupo de lactancia materna.
Conclusiones:
- Las madres lactantes mantienen naturalmente niveles más altos de vitamina D.
- La lactancia no parece agotar significativamente las reservas maternas de vitamina D.
- La evidencia actual no apoya la suplementación rutinaria de vitamina D basada únicamente en el estado de lactancia materna.

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:25Role of Vitamins in Maintaining Bone Health
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
