Organización de comics en la biblioteca

[ES] La apuesta por el cómic en las bibliotecas es cada vez mayor y sus consecuencias se hacen evidentes. Pero hay que conocer cómo se puede gestionar una sección dedicada al cómic. En este artículo se explica cómo afrontar la adquisición de este material así como el modo en que se organiza, ordena, presenta y difunde entre los usuarios

EL ESTUDIO DE LOS CURRÍCULOS OFICIALES DE CIENCIAS NATURALES EN EL MARCO DEL CONOCIMIENTO ESCOLAR: TENDENCIAS INVESTIGATIVAS

En el marco de la tesis doctoral “El Conocimiento Escolar en los Lineamientos Curriculares, los Estándares Básicos de Competencias y los Derechos Básicos del Aprendizaje para el área de Ciencias Naturales en Colombia: Estudio de caso”, se llevó a cabo una revisión de antecedentes investigativos para poder contar con una aproximación del estado actual de la investigación de los currículos oficiales en ciencias. Para este fin se desarrolló una ruta que inició con la definición de los criterios de búsqueda y llegó hasta la identificación y análisis de las tendencias a partir de la revisión a profundidad de los documentos seleccionados. Los resultados nos indican la preponderancia que ha venido tomando la investigación de los currículos oficiales de ciencias desde diferentes perspectivas, sin embargo son escasas las investigaciones que dan cuenta del conocimiento escolar en los currículos oficiales de ciencias naturales

Comparative life cycle analysis between commercial porcelain stoneware and new ones designed by using volcanic scraps

: To achieve carbon neutrality by 2050, many companies have started implementing sustainability policies. The aim of this work, as result of collaboration between Universities and companies, is to assess the environmental impacts associated with the production of alternative formulations of porcelain stoneware. The proposed formulations contain extraction scraps and chamotte and have promising technological properties. A comparative analysis of the life cycle in three different scenarios was carried out to assess the environmental footprint of the final products. The analyzed scenarios were a glazed porcelain stoneware (which was taken as a reference and is commercially available), a porcelain stoneware containing pumice scraps, and one containing volcanic lapillus scraps. It was observed that the transportation of raw materials has the largest environmental impact, followed by the production and extraction of the raw materials themselves. From the performed analysis, it was possible to observe that by replacing the currently used materials by the ones hereby studied, environmental benefits can be obtained. In particular, depending on the considered pollutant, the environmental impact can be reduced between a minimum of about 8 % (Freshwater Aquatic Ecotoxicity category) to a maximum of 48 % (Acidification category). In a time when raw materials supply is difficult, the use of scraps, which would otherwise be disposed of, is particularly interesting and can lead to the production of an environmentally friendly product

Hypertrophic pachymeningitis, associated with eosinophilic granulomatosis with polyangiitis, and ANCA-negative serology

Background: Hypertrophic pachymeningitis (HP) is a disease with diverse aetiologies, including the autoimmune one, either associated with antineutrophil cytoplasmic antibodies or immunoglobulin G4. Case description: A 65-year-old woman with a history of systemic arterial hypertension, presented with intense progressive headaches. HP and hemispheric vasogenic oedema were observed by nuclear magnetic resonance (NMR) study. During the six months before the headache, she had developed progressive hearing loss which she attributed to age. A biopsy of dura mater showed necrotising vasculitis with peripheral inflammatory infiltrate, made up of accumulations of epithelioid cells and multinucleated giant cells, and abundant eosinophils. A final diagnosis of HP with eosinophilic granulomatosis with polyangiitis (EGPA) was made. Discussion: The patient had eosinophilic granulomatosis with polyangiitis (EGPA) histology, ANCA-negative serology and HP. This case is important because it shows that EGPA seems to have a spectrum of clinical diseases, including HP with negative serology, and bilateral sensorineural hearing loss. Conclusion: We are facing a wide spectrum of EGPA, breaking the paradigm of only systemic involvement

Cardiometabolic health in people with HIV: expert consensus review

Objectives To develop consensus data statements and clinical recommendations to provide guidance for improving cardiometabolic health outcomes in people with HIV based on the knowledge and experience of an international panel of experts.Methods A targeted literature review including 281 conference presentations, peer-reviewed articles, and background references on cardiometabolic health in adults with HIV published between January 2016 and April 2022 was conducted and used to develop draft consensus data statements. Using a modified Delphi method, an international panel of 16 experts convened in workshops and completed surveys to refine consensus data statements and generate clinical recommendations.Results Overall, 10 data statements, five data gaps and 14 clinical recommendations achieved consensus. In the data statements, the panel describes increased risk of cardiometabolic health concerns in people with HIV compared with the general population, known risk factors, and the potential impact of antiretroviral therapy. The panel also identified data gaps to inform future research in people with HIV. Finally, in the clinical recommendations, the panel emphasizes the need for a holistic approach to comprehensive care that includes regular assessment of cardiometabolic health, access to cardiometabolic health services, counselling on potential changes in weight after initiating or switching antiretroviral therapy and encouraging a healthy lifestyle to lower cardiometabolic health risk.Conclusions On the basis of available data and expert consensus, an international panel developed clinical recommendations to address the increased risk of cardiometabolic disorders in people with HIV to ensure appropriate cardiometabolic health management for this population
