Netflix's decision to add games to its traditional content catalogue in November 2021 is perceived as a bet whose realisation is still uncertain. This study examines the first months of this new service from the company and seeks to find out how this content has been integrated into the platform, what kind of entertainment is offered and how it fits into the company's strategy, as well as how it has been received by users and subscribers. The methodology is based on a quantitative and qualitative triangulation of methods collected in an analysis sheet for each of the games in the sample (n=14). The results reflect that in these first months, the games offered are aimed to provide light entertainment and reinforce the value of the Netflix subscription, even if the games are gradually oriented towards a transmedia logic or serve to reinforce other content on the platform. In addition, the new data Netflix receives from its subscribers when they view content on the platform and their interaction with the new content could be an important asset for the future of the company.

The announcement of the State of Alarm in Spain in March 2020 brought with it a period of great information intensity in traditional and digital media. The extraordinary nature of the measure, which provided the Government with exceptional measures to confront the Covid-19 pandemic, gave rise to a tremendously polarized scenario. In this context, some webs known for the dissemination of disinformation campaigns and, even, the promotion of ideas closes to the alt-right, were especially active in networks promoting the dissemination of ideological content with the aim of capturing traffic for subsequent monetization through advertising. This work follows the activity around of two of these webs on Twitter, Caso Aislado and Periodista Digital, with the intention of determinate their role in the political polarization. For more than two months, more than 100,000 tweets were captured, stored and studied using R software and various analysis algorithms to determine their social activity, the possible presence or not of bots or automated profiles, the nature of the content and the emotional charge associated with it. There is an intense organized activity around both portals through a high percentage of apparently automated accounts and the support of influencers profiles. Although with differences inherent around each web, it is possible to glimpse an intentional coordination through campaigns that combine content, use of support accounts and automations.

This paper presents a bibliographic review of the treatment of laryngeal pathologies using direct intracordal administration of various different drugs. The evidence published essentially shows that the most drugs for which the most experience is available that are administered by this route are glucocorticoids, hyaluronic acid, cidofovir, botulinum toxin, and fibroblast growth factors. These drugs improved the clinical variables evaluated in the different laryngeal pathologies described. In conclusion, intracordal administration allows the drug to provide a local therapeutic action, without the need for high systemic concentrations that lead to an increased risk of adverse effects. However, more studies are required to support their use in clinical practice and to include other drugs that may also be beneficial in laryngeal pathologies. [ABSTRACT FROM AUTHOR]

Intravenous administration of lipid emulsions represents an increasingly widely-used alternative to reverse cardiac and neurological toxicity caused by high doses of drugs like local anaesthetics. In order to ensure fast, safe administration, dispensing and administration of the lipid emulsion in surgical and anaesthesiology services needs to be governed by a protocol. This paper describes the case of a patient subjected to orthopaedic surgery after administration of local anaesthetics in whom toxicity appeared and was reversed quickly and effectively thanks to the prior implementation of a protocol for action.

We analyze the effects of macroeconomic fluctuations, as well as episodes of financial instability and inflation, on inequality indicators in Chile for the period 1960-2014. The relationship between episodes of crisis and fluctuations on levels of inequality are estimated from an event study, finding that they are related to fluctuations in inequality. In addition, we perform econometric estimates where inequality indicators relate to different macroeconomic variables and educational performance. The main conclusions are that banking and inflation crises, as well as periods of severe cyclical contractions, tend to increase the levels of inequality in Chile. [ABSTRACT FROM AUTHOR]

Introduction: Oxidative stress has been implicated in the development and progression of vascular calcification (VC). However, this causal association remains a matter of controversy. Objective: To analyze in an experimental model of chronic renal failure (CRF), the effect of oxidative stress on the development and progression of the VC, assessing the implication of microRNA-377 (miR-377). Material and methods: Two groups of Wistar rats with CRF were studied. Group 1 received normal diet in phosphorus (CRF+NP). Group 2 received a high phosphorus (CRF+HP) diet. A group of sham rats was included. After 20 weeks, the rats were sacrificed. Results: Serum phosphorus and parathormone did not increase in the CRF+HP group compared to CRF+NP, but fibroblast growth factor 23 (FGF23) levels significantly increased. In the CRF+NP group, aortic calcium content increased three-fold over the sham group, a 17-fold increase in the CRF+HP group, where the bone mineral density in the proximal tibia decreased significantly. In the IRC+NP group, the expression of miR-377 decreased by 65%, with no additional effect detected of the diet with high phosphorus content. In the IRC+NP group, the protein expression of mitochondrial superoxide dismutase 2 (SOD-2) increased 3-fold, and in the IRC+HP group it increased up to 6-fold. Conclusions: CRF, with or without high phosphorus dietary content, triggered the descent of miR-377. Excess phosphorus increased SOD-2 as a compensatory mechanism to curb oxidative stress and vascular damage. Controlling phosphorus content in the diet when the renal impairment function is compromised will reduce the vascular damage produced due oxidative stress, among other factors.

Objetives: Assess the role of the catalase antioxidant enzyme in the vascular calcification process associated with chronic renal failure (CRF) and its effect on bone mass. Material and methods: Wild type C57/BL6J mice (WT) and transgenic mice (TG) were used, that overexpress the catalase enzyme, to which CRF was induced. Control WT and TG mice were used in simulated intervention. After 16 weeks, the mice were sacrificed, with serum samples taken for biochemical markers as well as residual pieces of kidney, aorta and tibias. An in vitro model of primary culture of smooth vascular muscle cells (SVMC) taken from the WT and TG aorta which underwent eight days of 3 mM phosphorus and 2 mM calcium calcifying medium. Results: A significant increase in Runx2 gene expression, calcium renal deposit and bone structure deterioration at trabecular level was only detected in WT mice with CRF. This was not observed in TG mice with CRF. Only in the case of WT mice SVMC, did added calcification medium raise calcium levels, proteic Runx2 expression and the reactive oxygen species of mitochondria with low catalase enzyme. Conclusions: Calcifying catalase over-expression was observed in both in vivo and in vitro, with in vivo showing that this reduction was accompanied by an improvement in bone parameters under study.

This article argues that, given the strong income concentration in Mexico, and the narrowness of the income tax base, it is very difficult to realize a tax reform that is redistributive, and increases tax collection. For that purpose, an applied model of general equilibrium was built, which includes, among some other things: a disaggregation of homes in 10 income levels, the tax and transferring structures of the country, and the productive and consumer spheres. The scenario confirms that to achieve a significant addition in tax collection, and, at the same time, to diminish the income inequality (measured by the Gini coefficient), imply increases of rates and bases, which is difficult to achieve in the present conditions.

Resumen Objetivo Analizar la utilidad de la fase angiogammagráfica de la gammagrafía ósea en 3 fases como posible método de cribado en el diagnóstico de infección de prótesis de cadera y de rodilla, previa a la realización de la gammagrafía con leucocitos marcados. Material y métodos Se analizaron prospectivamente 120 pacientes (70 mujeres y 50 hombres) con edad media de 71 ± 11 años y sospecha clínica de infección de prótesis de cadera (n = 63) o rodilla (n = 57), a los que se realizó gammagrafía ósea en 3 fases (angiogammagrafía, fase vascular y fase ósea) y gammagrafía con leucocitos marcados con 99m Tc-HMPAO. El diagnóstico definitivo se realizó mediante estudio microbiológico o seguimiento clínico mínimo de 12 meses. Resultados Se estableció el diagnóstico de infección de la prótesis articular en 18/120 pacientes: 10 pacientes con prótesis de cadera y 8 pacientes con prótesis de rodilla. La angiogammagrafía fue positiva en 15/18 pacientes infectados y en 21/102 pacientes no infectados, mostrando una sensibilidad del 83%, una especificidad del 79% y un valor predictivo negativo del 97%. La gammagrafía con leucocitos marcados mostró una sensibilidad y una especificidad del 72 y del 95%, respectivamente. Si se realizara la gammagrafía con leucocitos marcados exclusivamente a los pacientes con angiogammagrafía positiva, se reduciría un 70% de gammagrafías con leucocitos practicadas. No hubo ningún caso de infección con gammagrafía con leucocitos marcados positiva y angiogammagrafía negativa. Conclusiones La angiogammagrafía es una buena técnica de cribado de infección de prótesis articulares de cadera y rodilla, disminuyendo significativamente el número de gammagrafías con leucocitos marcados, sin afectar la sensibilidad de la técnica. Aim To evaluate the impact of the angioscintigrapy of the three phase bone scan as screening method to rule out infection of the hip and knee prosthesis prior to performing the 99m Tc-HMPAO leukocyte scintigraphy. Material and methods A total of 120 (70 women, 50 men; mean age 71 ± 11 years) with clinical suspicion of hip (n = 63) or knee (n = 57) infection of the prosthesis and clinical suspicion of infection were evaluated prospectively. All patients underwent three-phase bone scan (angioscintigraphy, vascular and bone phase) and 99m Tc-HMPAO-labelled white blood cell scintigraphy. Final diagnosis of infection was made by microbiological documentation or clinical follow-up for at least 12 months. Results Eighteen out of 120 patients were diagnosed of infection of hip prosthesis (n = 10) or knee prosthesis (n = 8). The angioscintigraphy was positive in 15/18 infected cases and in 21/102 of the non-infected cases with a sensitivity of 83%, specificity of 79% and negative predictive value of 97%. Sensitivity and specificity of 99m Tc-HMPAO leukocyte scintigraphy were 72% and 95%, respectively. If the leukocyte labeled scintigraphies had been used exclusively for patients with positive angioscintigraphy, this would have saved up to 70% of the 99m Tc-HMPAO leukocyte scintigraphies performed. There were no cases of infection with positive labeled leukocyte scintigraphy and negative angioscintigraphy. Conclusion Angioscintigraphy (blood flow phase of bone scan) is a useful technique for screening for hip and knee joint prosthesis infection, significantly reducing the need for 99m Tc-HMPAO leukocyte scintigraphy without affecting the sensitivity of the technique.

Mexico has two main sources of ilmenite, in the Oaxaca and Chiapas states. Ilmenite is an oxide composed by iron and titanium generally accompanied with apatite. About six tons of small cubic rocks mainly composed of ilmenite were found in San Lorenzo Tenochtitlan (Veracruz state), where Olmec culture flourished. This rock type was the object of study. Samples were observed by an electron scanning microscopy (JEOL JSM- 6300 and microsonde JEOL JXA 8300R) and WDS analyses, which contributed to determine that, by comparison, the most probable source of these samples is Huitzo Precambrian rocks in Oaxaca state.

Introduction: In the current context of digital media and social networks, in which citizens have gone from being consumers to „prosumers‟ of information, they begin to demand transparency from the government and to become aware of their collective potential to change the world in which they live, buy and vote. Method: This article uses the case study technique to analyse open data portals and identify the technological and strategic elements that make it easier for citizens to collaboratively re-use and retransmit information that allows them to make informed decisions and construct their social reality. Results and conclusions: There is a „movement‟ of open data initiatives, which are mostly dedicated to release public financial and political information; to organise it mainly according to geopolitical criteria; and make it available to citizens through technological standards and participation models that show the way to achieve change.
