Does TikTok allow quality debate? A case study on poverty

This study analyses temporary employees’ perceptions and This article analyzes whether the features of TikTok allow for meaningful debates and how they are conducted. To do so, we used a case study approach: user conversations about socially excluded individuals in a context marked by the Covid-19 pandemic and subsequent economic crisis, which have exacerbated hardships in developing countries. A total of 100 videos published in Spain since 2020 on this topic, along with 38,462 comments, are examined. We performed a content analysis of the videos, considering their thematic, technical, and stylistic characteristics. Additionally, we conducted a textual analysis of the comments taking into account the authorial and conversational dimensions. The study concludes that the structure of TikTok does not enable high-quality debates in this case study. The videos provide an episodic view of the topics, and on average users participate only once expressing opinions based on personal experiences or existing biases. Moreover, the debate is muddled in this specific topic due to intergenerational conflicts. Judgmental attitudes lead to messages that are both cruel in the form of advice and expressions of humor. The analysis reveals a strong sentiment of aporophobia in the opinions expressed on this platform. Therefore, it is advisable to recommend the inclusion of this marginalized group among the protected groups in the community guidelines.Este artículo analiza si las características de TikTok permiten debates significativos y cómo se realizan. Para ello se utiliza un caso de estudio: las conversaciones de los usuarios sobre las personas en riesgo de exclusión social en un contexto, el de la pandemia y la crisis económica, en el que se han incrementado las privaciones en los países en desarrollo. Se examinan 100 vídeos publicados en España y producidos desde 2020 con este tema, así como 38.462 comentarios. Se aplica un análisis de contenido a los vídeos que incluye características temáticas, técnicas y de estilo; y un análisis textual a los comentarios en el que se tiene en cuenta la dimensión autoral y conversacional. Se concluye que la estructura de TikTok no permite un debate de calidad en este caso de estudio, porque los vídeos ofrecen una visión episódica de los temas, porque los usuarios intervienen, de media, una vez y lo hacen para expresar una opinión basada en experiencias propias o en prejuicios existentes, y porque el debate se enturbia, en este tema concreto, por la existencia de un enfrentamiento generacional. El enjuiciamiento conduce a posturas que generan mensajes crueles, tanto en forma de consejos como en expresiones de humor. El análisis permite afirmar que, en la opinión evidenciada en esta plataforma, existe un fuerte sentimiento de aporofobia. Conviene por ello recomendar la inclusión de este colectivo entre los grupos protegidos en las normas de esta comunidad

RICORS2040 : The need for collaborative research in chronic kidney disease

Chronic kidney disease (CKD) is a silent and poorly known killer. The current concept of CKD is relatively young and uptake by the public, physicians and health authorities is not widespread. Physicians still confuse CKD with chronic kidney insufficiency or failure. For the wider public and health authorities, CKD evokes kidney replacement therapy (KRT). In Spain, the prevalence of KRT is 0.13%. Thus health authorities may consider CKD a non-issue: very few persons eventually need KRT and, for those in whom kidneys fail, the problem is 'solved' by dialysis or kidney transplantation. However, KRT is the tip of the iceberg in the burden of CKD. The main burden of CKD is accelerated ageing and premature death. The cut-off points for kidney function and kidney damage indexes that define CKD also mark an increased risk for all-cause premature death. CKD is the most prevalent risk factor for lethal coronavirus disease 2019 (COVID-19) and the factor that most increases the risk of death in COVID-19, after old age. Men and women undergoing KRT still have an annual mortality that is 10- to 100-fold higher than similar-age peers, and life expectancy is shortened by ~40 years for young persons on dialysis and by 15 years for young persons with a functioning kidney graft. CKD is expected to become the fifth greatest global cause of death by 2040 and the second greatest cause of death in Spain before the end of the century, a time when one in four Spaniards will have CKD. However, by 2022, CKD will become the only top-15 global predicted cause of death that is not supported by a dedicated well-funded Centres for Biomedical Research (CIBER) network structure in Spain. Realizing the underestimation of the CKD burden of disease by health authorities, the Decade of the Kidney initiative for 2020-2030 was launched by the American Association of Kidney Patients and the European Kidney Health Alliance. Leading Spanish kidney researchers grouped in the kidney collaborative research network Red de Investigación Renal have now applied for the Redes de Investigación Cooperativa Orientadas a Resultados en Salud (RICORS) call for collaborative research in Spain with the support of the Spanish Society of Nephrology, Federación Nacional de Asociaciones para la Lucha Contra las Enfermedades del Riñón and ONT: RICORS2040 aims to prevent the dire predictions for the global 2040 burden of CKD from becoming true

Actas de las V Jornadas ScienCity 2022. Fomento de la Cultura Científica, Tecnológica y de Innovación en Ciudades Inteligentes

ScienCity es una actividad que viene siendo continuada desde 2018 con el objetivo de dar a conocer los conocimientos y tecnologías emergentes siendo investigados en las universidades, informar de experiencias, servicios e iniciativas puestas ya en marcha por instituciones y empresas, llegar hasta decisores políticos que podrían crear sinergias, incentivar la creación de ideas y posibilidades de desarrollo conjuntas, implicar y provocar la participación ciudadana, así como gestar una red internacional multidisciplinar de investigadores que garantice la continuación de futuras ediciones. En 2022 se recibieron un total de 48 trabajos repartidos en 25 ponencias y 24 pósteres pertenecientes a 98 autores de 14 instituciones distintas de España, Portugal, Polonia y Países Bajos.Fundación Española para la Ciencia y la Tecnología-Ministerio de Ciencia, Innovación y Universidades; Consejería de la Presidencia, Administración Pública e Interior de la Junta de Andalucía; Estrategia de Política de Investigación y Transferencia de la Universidad de Huelva; Cátedra de Innovación Social de Aguas de Huelva; Cátedra de la Provincia; Grupo de investigación TEP-192 de Control y Robótica; Centro de Investigación en Tecnología, Energía y Sostenibilidad (CITES

AT<inf>2</inf>R stimulation with C21 prevents arterial stiffening and endothelial dysfunction in the abdominal aorta from mice fed a high-fat diet

The aim of the present study was to evaluate the effect of Compound 21 (C21), a selective AT2R agonist, on the prevention of endothelial dysfunction, extracellular matrix (ECM) remodeling and arterial stiffness associated with diet-induced obesity (DIO). Five-week-old male C57BL/6J mice were fed a standard (Chow) or high-fat diet (HF) for 6 weeks. Half of the animals of each groupwere simultaneously treated with C21 (1mg/kg/day, in the drinking water), generating four groups: Chow C, Chow C21, HF C, and HF C21. Vascular function and mechanical properties were determined in the abdominal aorta. To evaluate ECM remodeling, collagen deposition and TGF-β1 concentrations were determined in the abdominal aorta and the activity of metalloproteinases (MMP) 2 and 9 was analyzed in the plasma. Abdominal aortas fromHF C mice showed endothelial dysfunction as well as enhanced contractile but reduced relaxant responses to Ang II. This effect was abrogated with C21 treatment by preserving NO availability. A left-shift in the tension-stretch relationship, paralleled by an augmented β-index (marker of intrinsic arterial stiffness), and enhanced collagen deposition and MMP-2/-9 activities were also detected in HF mice. However, when treated with C21, HF mice exhibited lower TGF-β1 levels in abdominal aortas together with reduced MMP activities and collagen deposition compared with HF C mice. In conclusion, these data demonstrate that AT2R stimulation by C21 in obesity preserves NO availability and prevents unhealthy vascular remodeling, thus protecting the abdominal aorta in HF mice against the development of endothelial dysfunction, ECM remodeling and arterial stiffness
