A partir de un trabajo etnográfico basado en estudios de caso, se muestra la percepción de vida y trabajo de cinco artesanas de San Juan Chamula, Chiapas, quienes dan cuenta de cómo, al aprender a tejer, su cuerpo y voluntad se combinan para llegar a ser expertas en el arte del tejido de prendas de lana de uso ceremonial, al mismo tiempo que efectúan las faenas hogareñas y del campo. De los testimonios de las artesanas se desprende, además, una estrecha relación con la etnoteoría pedagógica local desarrollada por Margarita Martínez que implica los ámbitos de la interacción familiar y la corporeidad. El relato biográfico y la memoria familiar dan cuenta del valor cultural que representa este tipo de producción exclusiva para la población local de Los Altos de Chiapas.

Introduction The incidence of type 2 diabetes mellitus (T2DM) is increasing worldwide. When diagnosed, many patients already have organ damage or advance subclinical atherosclerosis. An early diagnosis could allow the implementation of lifestyle changes and treatment options aimed at delaying the progression of the disease and to avoid cardiovascular complications. Different scores for identifying undiagnosed diabetes have been reported, however, their performance in populations of southern Europe has not been sufficiently evaluated. The main objectives of our study are: to evaluate the screening performance and cut-off points of the main scores that identify the risk of undiagnosed T2DM and prediabetes in a Spanish population, and to develop and validate our own predictive models of undiagnosed T2DM (screening model), and future T2DM (prediction risk model) after 5-year follow-up. As a secondary objective, we will evaluate the atherosclerotic burden of the population with undiagnosed T2DM. Methods and analysis Population-based prospective cohort study with baseline screening, to evaluate the performance of the FINDRISC, DANISH, DESIR, ARIC and QDScore, against the gold standard tests: Fasting plasma glucose, oral glucose tolerance and/or HbA1c. The sample size will include 1352 participants between the ages of 45 and 74 years. Analysis: sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio positive, likelihood ratio negative and receiver operating characteristic curves and area under curve. Binary logistic regression for the first 700 individuals (derivation) and last 652 (validation) will be performed. All analyses will be calculated with their 95% CI; statistical significance will be p

The Monk Parakeet ( Myiopsitta monachus ) is native to South America and has been introduced by the pet market to several countries around the world. In this note, we compiled records for this species in Mexico, also reporting the first sight-recording of this species in the state of Michoacan and several nesting localities within the Metropolitan area of Mexico City. Most records are from escaped/released individuals from captivity. Also, we review the negative effects that this invasive species has had around the world. All records for this species in Mexico suggest the possible beginning of a massive invasion that could have dramatic negative ecological and economical effects throughout this biodiverse country.
