PATOLOGÍAS CAUSADAS POR EXPOSICIÓN AL AMIANTO.

La presente investigación pretende dar a conocer la influencia que tiene el amianto en el desarrollo de patologías pulmonares. La revisión de la literatura, pone en evidencia una fuerte vinculación entre este mineral y enfermedades como el mesotelioma, cáncer de pulmón y asbestosis; que se  producen en personas que trabajaron en la industria del asbesto, razón por la cual tuvieron una exposición directa a éste mineral. Sin embargo, sorprende que tanto la revisión bibliográfica, como la de casos ponen de manifiesto que esta fibra resulta ser perjudicial para otros individuos que a pesar de no estar expuestos directamente, si inhalan en su momento éstas peligrosas fibras. (Escobar, 2012) Por otra parte, se pretende abordar cada una de las patologías relacionadas con el amianto explicando el comportamiento de la fibra dentro del organismo, el daño que este causa y su respectivo tratamiento

Diminishing benefits of urban living for children and adolescents’ growth and development

Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified
