Asbesto en Colombia: un enemigo silencioso / Asbestos in Colombia: A silent enemy

El asbesto es un grupo de minerales no metálicos fibrosos, compuestos de silicatos de doble cadena que poseen gran resistencia a la tensión y la degradación química y conductividad térmica baja. A pesar de la evidencia experimental y poblacional de que dichos minerales son agentes cancerígenos y de su reconocimiento como tales por la Organización Mundial de la Salud, aún se los sigue usando en muchos países, Colombia incluida, a costa de la salud de los trabajadores, lo que se ha convertido en un problema mundial por el desarrollo de enfermedades asociadas a estos minerales en individuos expuestos. En este artículo se hace una revisión sobre el asbesto, las enfermedades asociadas a él y la normatividad mundial y colombiana frente al mismo; además, se plantea la conveniencia de evaluar la utilidad de la monitorización genética como complemento para el seguimiento de los individuos expuestos, que permita mejorar la vigilancia en nuestro país del desarrollo de cáncer de pulmón, mesotelioma y otras enfermedades asociadas con el asbesto.

Asbestos is a group of fibrous non-metallic minerals, composed of double chain silicates, that shows high resistance to tension and chemical degradation and low thermal conductivity. Despite being recognized as carcinogenic agents by the World Health Organization (WHO), based on experimental evidences and population studies, asbestos are still used in many countries at the expense of the health of workers. This has become a worldwide problem associated with the increase of asbestos-related diseases in exposed persons. In this article, we review asbestos and their associated diseases; the use, exposure and existing regulations on asbestos both in Colombia and in other countries. Finally, we raise the possibility of evaluating the usefulness of genetic monitoring in addition to following-up exposed individuals. This would enable a better surveillance in our country with respect to lung cancer, mesothelioma and other asbestos-related diseases.

A vitamin, mineral, herb dietary supplement effect on blood glucose in uncontrolled type II diabetic subjects

We tested a dietary supplement formulated with a synergistic combination of vitamins, minerals, herbals in a group of 15 patients with uncontrolled diabetes type II. The supplement was given for 30 days. Fasting blood glucose was measured prior to the supplementation and at the end of the 30 days treatment period. Blood glucose was significantly reduced in all patients with no adverse effects. This orthomolecular correction of faulty glucose metabolism with a combination of nontoxic, safe and fairly inexpensive nutraceuticals needs to be further substantiated. Nervertheless the idea of correcting metabolism with micronutrients is a new concept of genetic nutritioneering that seems appealing and cost effective
