Evidence of spatial clustering of childhood acute lymphoblastic leukemia cases in Greater Mexico City: report from the Mexican Inter-Institutional Group for the identification of the causes of childhood leukemia

BackgroundA heterogeneous geographic distribution of childhood acute lymphoblastic leukemia (ALL) cases has been described, possibly, related to the presence of different environmental factors. The aim of the present study was to explore the geographical distribution of childhood ALL cases in Greater Mexico City (GMC).MethodsA population-based case-control study was conducted. Children <18 years old, newly diagnosed with ALL and residents of GMC were included. Controls were patients without leukemia recruited from second-level public hospitals, frequency-matched by sex, age, and health institution with the cases. The residence address where the patients lived during the last year before diagnosis (cases) or the interview (controls) was used for geolocation. Kulldorff’s spatial scan statistic was used to detect spatial clusters (SCs). Relative risks (RR), associated p-value and number of cases included for each cluster were obtained.ResultsA total of 1054 cases with ALL were analyzed. Of these, 408 (38.7%) were distributed across eight SCs detected. A relative risk of 1.61 (p<0.0001) was observed for the main cluster. Similar results were noted for the remaining seven ones. Additionally, a proximity between SCs, electrical installations and petrochemical facilities was observed.ConclusionsThe identification of SCs in certain regions of GMC suggest the possible role of environmental factors in the etiology of childhood ALL

Calidad de vida del paciente diabético tipo 2 relacionado con la alimentación y estilo de vida

Objetivo: Valorar la influencia de los hábitos de alimentación y estilo de vida sobre la calidad de vida del diabético tipo 2. Materiales y métodos: Se realiza un estudio transversal comparativo en la UMF 57 del IMSS. La muestra fue al azar como 8O pacientes, se aplico el cuestionario COOP-Darmouth y Food frecuency cuestionary. Se formaron dos grupos : Mala calidad n^30, buena n=50. Se seleccionaron de 50 a 70 años y de 10 a 30 años de evolución, se excluyeron incapacitados. Resultados: no hubo diferencia significativa al comparar la variables edad, glucosa, Índice de masa corporal (IMC), calorías y evolución de la enfermedad. Se utilizo la t de Student no pareada (P=NS)

La retórica y el debate como herramientas de aprendizaje

Convocatoria proyectos de innovación de Extremadura 2019/2020Se describe un proyecto llevado a cabo en el IES San Fernando (Badajoz) surgido del Departamento de Filosofía que tiene como objetivo principal mejorar las habilidades comunicativas del alumnado. Se pretendía que supieran hablar, transmitir ideas y opiniones, saber escuchar, compartir posturas, rebatir y estar preparados para cambiar de opinión. Otros objetivos del trabajo fueron: transmitir una visión de sociedad que se basa en el diálogo constructivo a través de una interacción respetuosa, rigurosamente fundamentada, reflexiva e inclusiva; lograr en los alumnos el desarrollo del pensamiento crítico y conseguir que comprendan la información que reciben, las inferencias y que sean capaces de evaluarla y generar nuevas propuestasExtremaduraES

Guidelines for the use of flow cytometry and cell sorting in immunological studies (second edition)

These guidelines are a consensus work of a considerable number of members of the immunology and flow cytometry community. They provide the theory and key practical aspects of flow cytometry enabling immunologists to avoid the common errors that often undermine immunological data. Notably, there are comprehensive sections of all major immune cell types with helpful Tables detailing phenotypes in murine and human cells. The latest flow cytometry techniques and applications are also described, featuring examples of the data that can be generated and, importantly, how the data can be analysed. Furthermore, there are sections detailing tips, tricks and pitfalls to avoid, all written and peer-reviewed by leading experts in the field, making this an essential research companion
