Estimadores compuestos en estadística regional: aplicación para la tasa de variación de la ocupación en la industria

This work is part of a project studying the performance of model basedestimators in a small area context. We have chosen a simple statisticalapplication in which we estimate the growth rate of accupation for severalregions of Spain. We compare three estimators: the direct one based onstraightforward results from the survey (which is unbiassed), and a thirdone which is based in a statistical model and that minimizes the mean squareerror.

Calcifications vasculaires et déficit en vitamine K: un facteur de risque modifiable dans l'insuffisance rénale chronique [Vascular calcifications and vitamin K deficiency: a modifiable risk factor in chronic kidney disease].

The mechanisms of vascular calcifications in chronic renal failure are complex. Apart for clotting factors, vitamin K-dependent proteins include matrix Gla protein. Glutamic acid residues in matrix Gla protein are carboxylated by vitamin K-dependent gamma-carboxylase, which enables it to inhibit calcification. The purpose of this review is to discuss available evidence implicating vitamin K as a modifiable risk factor in the pathogenesis of vascular calcification in renal diseases.
