La Vasa Previa es una condición poco común que representa un riesgo inminente de muerte fetal si no es diagnosticada oportunamente, por lo que el diagnóstico prenatal es fundamental para evitar los resultados perinatales devastadores. Debido a que actualmente las mujeres se someten con mayor frecuencia al uso de técnicas de tecnología de reproducción asistida, es probable que exista un incremento de la incidencia de vasa previa en las próximas décadas. Objetivo: revisar la literatura sobre el uso de tecnología de reproducción asistida y riesgo de vasa previa. Método: Se realizó una búsqueda en cinco bases de datos (PubMed, Scopus, ProQuest, Sciencedirect y PMC), en busca de estudios observacionales (casos y controles, transversales y cohortes), revisiones sistemáticas, metaanálisis completos, de cualquier nacionalidad e idioma, de los últimos 10 años; esta selección fue...

This work presents results of objective measurements of vicuña fiber obtained from wild animals and community management in Jujuy Province, Argentina, from 2014 to 2015. The aim of this paper is to provide technical information to improve the method of shearing and fiber classification, and also describe the quality attributes of the vicuña fiber in this geographic region. Mean fiber diameter (MFD) and staple length (SL) were measured on three different sites of fleece. The influence of the animal sex, the method of shearing and the site of fleece were also studied. Results indicate that sex has not significant effect of measured parameters, although the sampling site of fleece has affected these fiber caracteristics. The method of shearing may be a significant contributor to staple length variation.
