El microblogging como marco de interés en la información alimentaria y de estilos de vida saludables = Microblogging as interesting frame in food information and healthy lifestyles

RESUMEN Introducción El microblogging, o nanoblogging, es un servicio que permite a sus usuarios enviar y publicar mensajes breves, no solo de texto, sino también con enlaces multimedia, imágenes, links a publicaciones, etc… El microblogging tiene una característica fundamental: la rapidez, la inmediatez de la reacción. Twitter es probablemente el microblogging más popular. En este trabajo presentamos las observaciones del fenómeno del microblogging y su relación con la información alimentaria y de estilos de vida saludables Estado actual: La población general utiliza cada vez más las redes sociales para buscar y compartir información en materia de salud, especialmente por medio de herramientas sencillas y rápidas, como los microbloggins y no siempre el divulgador en salud utiliza con eficacia estas estrategias de comunicación Conclusiones. Es imprescindible implementar el microblogging en las estrategias de divulgación de información alimentaria y estilos de vida saludables, dándole la importancia que presenta en los medios de comunicación/divulgación de masas. Para ello deberemos de contar con la presencia de instituciones o individuos particulares que sean referentes de influencia en la esfera del microblogging, conozcan el lenguaje específico y las estrategias (tan cambiantes) de comunicación y que a su vez, estén íntimamente ligados al campo académico y científico Palabras clave: Microblogging. Medios de comunicación social, Influencers. Información alimentaria. Estilos de vida saludables ABSTRACT Introduction Microblogging or nanoblogging is a new form of communication in which users can send short posts distributed by instant messages, mobile phones, email or the Web. Microblogging has a key characteristic: the rapid and we might even say, the immediacy of the reaction Twitter, is probably the most popular microblogging tool. In this paper, we present our view of the microblogging phenomena by analyzing the relationships between nanobloggins, food information and healthy lifestyles. Current State. People increasingly use social networks to seek and share health information, especially by means of simple and rapid tools, such as microbloggins. Health professionals are not always able to use efficiently these strategies of communication Conclusions. Microblogging is essential in the strategies for diffusion of food information and healthy lifestyles, and deserve specific attention in mass media planning. We must rely on the presence of institutions or people in particular who can be influencers in the sphere of the microblogging, know the specific language and the strategies (so changeable) of communication, which in turn, are intimately tied to the academic and scientific field Key Words: Microblogging, social media, Influencers, Food information, healthy ways of life doi: http://dx.doi.org/10.20318/recs.2016.313

Inmigración y mercado laboral: aproximación a su estudio en la Comunidad de Madrid

In this article we study the role of the immigrant population in the labour market of the Community of Madrid. In the first place we analyze the structure by sex and age of this collective, as well as its levels of instruction. These socio demographic variables have repercussion in the rates of activity of the immigrants and in the possible labour niches that they tend to occupy. In this sense, there is a clear association among the variables of sex, origin and type of labour occupation. Also other characteristics related to the employment of immigrant population are observed, such as rates of unemployment, labour conditions, self-employment, etc.En este artículo se estudia el papel que la población inmigrante tiene en el mercado laboral de la Comunidad de Madrid. En primer lugar se analiza la estructura por edad y sexo de este colectivo, así como sus niveles de instrucción. Estas variables sociodemográficas tienen, sin duda, repercusión en las tasas de actividad de los inmigrantes y en los posibles nichos laborales que tienden a ocupar. En este sentido, existe una clara asociación entre las variables de sexo, procedencia y tipo de ocupación laboral. También se observan otras características relacionadas con el empleo de la población inmigrante, tales como sus tasas de paro, condiciones laborales, autoempleo, etc

The sensitivity of the Greenland Ice Sheet to glacial-interglacial oceanic forcing

Observations suggest that during the last decades the Greenland Ice Sheet (GrIS) has experienced a gradually accelerating mass loss, in part due to the observed speed-up of several of Greenland's marine-terminating glaciers. Recent studies directly attribute this to warming North Atlantic temperatures, which have triggered melting of the outlet glaciers of the GrIS, grounding-line retreat and enhanced ice discharge into the ocean, contributing to an acceleration of sea-level rise. Reconstructions suggest that the influence of the ocean has been of primary importance in the past as well. This was the case not only in interglacial periods, when warmer climates led to a rapid retreat of the GrIS to land above sea level, but also in glacial periods, when the GrIS expanded as far as the continental shelf break and was thus more directly exposed to oceanic changes. However, the GrIS response to palaeo-oceanic variations has yet to be investigated in detail from a mechanistic modelling perspective. In this work, the evolution of the GrIS over the past two glacial cycles is studied using a three-dimensional hybrid ice-sheet-shelf model. We assess the effect of the variation of oceanic temperatures on the GrIS evolution on glacial-interglacial timescales through changes in submarine melting. The results show a very high sensitivity of the GrIS to changing oceanic conditions. Oceanic forcing is found to be a primary driver of GrIS expansion in glacial times and of retreat in interglacial periods. If switched off, palaeo-atmospheric variations alone are not able to yield a reliable glacial configuration of the GrIS. This work therefore suggests that considering the ocean as an active forcing should become standard practice in palaeo-ice-sheet modelling

Optimized sound diffusers based on sonic crystals using a multiobjective evolutionary algorithm

Sonic crystals have been demonstrated to be good candidates to substitute for conventional diffusers in order to overcome the need for extremely thick structures when low frequencies have to be scattered, however, their performance is limited to a narrow band. In this work, multiobjective evolutionary algorithms are used to extend the bandwidth to the whole low frequency range. The results show that diffusion can be significantly increased. Several cost functions are considered in the paper, on the one hand to illustrate the flexibility of the optimization and on the other hand to demonstrate the problems associated with the use of certain cost functions. A study of the robustness of the optimized diffusers is also presented, introducing a parameter that can help to choose among the best candidates. Finally, the advantages of the use of multiobjective optimization in comparison with conventional optimizations are discussed.This work was partially supported by the Spanish "Ministerio de Economia y Competitividad" under the projects TEC2015-68076-R and DPI2015-71443-R.Redondo, J.; Sánchez Pérez, JV.; Blasco, X.; Herrero Durá, JM.; Vorlander, M.

Exploring the impact of atmospheric forcing and basal drag on the Antarctic Ice Sheet under Last Glacial Maximum conditions

Little is known about the distribution of ice in the Antarctic Ice Sheet (AIS) during the Last Glacial Maximum (LGM). Whereas marine and terrestrial geological data indicate that the grounded ice advanced to a position close to the continental-shelf break, the total ice volume is unclear. Glacial boundary conditions are potentially important sources of uncertainty, in particular basal friction and climatic boundary conditions. Basal friction exerts a strong control on the large-scale dynamics of the ice sheet and thus affects its size and is not well constrained. Glacial climatic boundary conditions determine the net accumulation and ice temperature and are also poorly known. Here we explore the effect of the uncertainty in both features on the total simulated ice storage of the AIS at the LGM. For this purpose we use a hybrid ice sheet shelf model that is forced with different basal drag choices and glacial background climatic conditions obtained from the LGM ensemble climate simulations of the third phase of the Paleoclimate Modelling Intercomparison Project (PMIP3). Overall, we find that the spread in the simulated ice volume for the tested basal drag parameterizations is about the same range as for the different general circulation model (GCM) forcings (4 to 6 m sea level equivalent). For a wide range of plausible basal friction configurations, the simulated ice dynamics vary widely but all simulations produce fully extended ice sheets towards the continental-shelf break. More dynamically active ice sheets correspond to lower ice volumes, while they remain consistent with the available constraints on ice extent. Thus, this work points to the possibility of an AIS with very active ice streams during the LGM. In addition, we find that the surface boundary temperature field plays a crucial role in determining the ice extent through its effect on viscosity. For ice sheets of a similar extent and comparable dynamics, we find that the precipitation field determines the total AIS volume. However, precipitation is highly uncertain. Climatic fields simulated by climate models show more precipitation in coastal regions than a spatially uniform anomaly, which can lead to larger ice volumes. Our results strongly support using these paleoclimatic fields to simulate and study the LGM and potentially other time periods like the last interglacial. However, their accuracy must be assessed as well, as differences between climate model forcing lead to a large spread in the simulated ice volume and extensión

Therapeutic targeting of HER2–CB2R heteromers in HER2-positive breast cancer

There is a subtype of breast cancer characterized by the overexpression of the oncogene HER2. Although most patients with this diagnosis benefit from HER2-targeted treatments, some do not respond to these therapies and others develop resistance with time. New tools are therefore warranted for the treatment of this patient population, and for early identification of those individuals at a higher risk of developing innate or acquired resistance to current treatments. Here, we show that HER2 forms heteromer complexes with the cannabinoid receptor CB2R, the expression of these structures correlates with poor patient prognosis, and their disruption promotes antitumor responses. Collectively, our results support HER2–CB2R heteromers as new therapeutic targets and prognostic tools in HER2+ breast cancer

Use of tocilizumab in kidney transplant recipients with COVID-1

Acute respiratory distress syndrome associated with coronavirus infection is related to a cytokine storm with large interleukin-6 (IL-6) release. The IL-6-receptor blocker tocilizumab may control the aberrant host immune response in patients with coronavirus disease 2019 (COVID-19) . In this pandemic, kidney transplant (KT) recipients are a high-risk population for severe infection and showed poor outcomes. We present a multicenter cohort study of 80 KT patients with severe COVID-19 treated with tocilizumab during hospital admission. High mortality rate was identified (32.5%), related with older age (hazard ratio [HR] 3.12 for those older than 60 years, P = .039). IL-6 and other inflammatory markers, including lactic acid dehydrogenase, ferritin, and D-dimer increased early after tocilizumab administration and their values were higher in nonsurvivors. Instead, C-reactive protein (CRP) levels decreased after tocilizumab, and this decrease positively correlated with survival (mean 12.3 mg/L in survivors vs. 33 mg/L in nonsurvivors). Each mg/L of CRP soon after tocilizumab increased the risk of death by 1% (HR 1.01 [confidence interval 1.004-1.024], P = .003). Although patients who died presented with worse respiratory situation at admission, this was not significantly different at tocilizumab administration and did not have an impact on outcome in the multivariate analysis. Tocilizumab may be effective in controlling cytokine storm in COVID-19 but randomized trials are needed

Ibero-American Consensus on Low- and No-Calorie Sweeteners: Safety, Nutritional Aspects and Benefits in Food and Beverages

International scientific experts in food, nutrition, dietetics, endocrinology, physical activity, paediatrics, nursing, toxicology and public health met in Lisbon on 2-4 July 2017 to develop a Consensus on the use of low- and no-calorie sweeteners (LNCS) as substitutes for sugars and other caloric sweeteners. LNCS are food additives that are broadly used as sugar substitutes to sweeten foods and beverages with the addition of fewer or no calories. They are also used in medicines, health-care products, such as toothpaste, and food supplements. The goal of this Consensus was to provide a useful, evidence-based, point of reference to assist in efforts to reduce free sugars consumption in line with current international public health recommendations. Participating experts in the Lisbon Consensus analysed and evaluated the evidence in relation to the role of LNCS in food safety, their regulation and the nutritional and dietary aspects of their use in foods and beverages. The conclusions of this Consensus were: (1) LNCS are some of the most extensively evaluated dietary constituents, and their safety has been reviewed and confirmed by regulatory bodies globally including the World Health Organisation, the US Food and Drug Administration and the European Food Safety Authority; (2) Consumer education, which is based on the most robust scientific evidence and regulatory processes, on the use of products containing LNCS should be strengthened in a comprehensive and objective way; (3) The use of LNCS in weight reduction programmes that involve replacing caloric sweeteners with LNCS in the context of structured diet plans may favour sustainable weight reduction. Furthermore, their use in diabetes management programmes may contribute to a better glycaemic control in patients, albeit with modest results. LNCS also provide dental health benefits when used in place of free sugars; (4) It is proposed that foods and beverages with LNCS could be included in dietary guidelines as alternative options to products sweetened with free sugars; (5) Continued education of health professionals is required, since they are a key source of information on issues related to food and health for both the general population and patients. With this in mind, the publication of position statements and consensus documents in the academic literature are extremely desirable
