ABSTRACT

Los corticoides son fármacos muy usados en la práctica clínica habitual que, sin embargo, se asocian a frecuentes efectos adversos neuropsiquiátricos. Se describe el caso clínico de un varón de setenta y un años que desarrolló síntomas maníacos tras toma de corticoides y que fue tratado de forma satisfactoria con quetiapina. A partir de este caso, se realiza una revisión de la manía inducida por corticoides (AU)


Corticosteroids are drugs widely used in routine clinical practice that are however associated with neuropsychiatric adverse effects. This paper describes the case of a seventy-one- year man who developed manic symptoms after taking with corticosteroids and was successfully treated with quetiapine and, on the other hand, reviews corticosteroid-induced mania (AU)

ABSTRACT

The current study presents the development and characterization of novel carrageenan nanobiocomposites showing enhanced water barrier due to incorporation of cellulose nanowhiskers (CNW). CNW, prepared by acid hydrolysis of highly purified α cellulose microfibers, were seen to have a length of around 25-50 nm and a cross section of ca. 5 nm when dispersed in the matrix. The nanobiocomposites were prepared by incorporating 1, 3, and 5 wt % of the CNW into a carrageenan matrix using a solution casting method. Morphological data (TEM and optical microscopy) of the nanocomposites containing CNW were compared with the morphology of the corresponding biocomposites containing the original cellulose microfibers and the differences discussed. Thermal stability by TGA, water vapor permeability, and percent water uptake were also determined. The main conclusion arising from the analysis of the results is that the nanobiocomposites containing 3 wt % of CNW exhibited the lowest reduction in water vapor permeability, that is, ca. 71%, and that this reduction was largely attributed to a filler-induced water solubility reduction. This fully biobased nanoreinforced carrageenan can open new opportunities for the application of this biopolymer in food-packaging and -coating applications.

ABSTRACT

Evalúa que la nueva tecnología farmacéutica, tanto de síntesis como de investigación (laboratorios I + D), y el uso de materias primas cuyos efectos toxicológicos son poco o nada conocidos conlleva la existencia de riesgos higiénicos exclusivos, que solo se presentan en este tipo de actividad industrial y cuya exposición puede ocasionar trastornos graves para la salud de los trabajadores y para los que resulta insuficiente establecer un sistema de prevención de riesgos laborales, contando unicamente con los métodos y medidas que habitualmente se adoptan en higiene industrial
