    Ante las restricciones contextuales derivadas de la pandemia de COVID19, la población organizada en microcomunidades ha implementado prácticas emergentes para contrarrestar los efectos causados por las medidas de confinamiento. Con el objetivo de analizar el rol de las redes sociales digitales en la manifestación de experiencias democráticas en microcomunidades, como respuesta a la pandemia de COVID19, se presenta un estudio de caso exploratorio etnográfico que aplica un modelo de análisis sociosemiótico. Los hallazgos muestran que las redes sociales funcionan como medio catalizador para la legitimación de experiencias democráticas dentro de la microcomunidad, independientemente de las regulaciones convencionales. Contextual constraints related to the COVID19 pandemic provoked that populations in microcommunities implemented emerging practices to strike back the effects caused by confinement measures. The study presents an ethnographic exploratory casestudy applying a sociosemiotic analysis model to analyze the role of Internet social networks as the expression of democratic practices in microcommunities in response to the COVID19 pandemic. The findings show that social networks function as a catalyst for legitimizing democratic experiences within the microcommunity independently of current regulations.

    Adolescence is a critical period in the consolidation of healthy lifestyles that can last into adulthood. To analyze changes in food consumption and eating behaviors in high-school adolescents during the first confinement, a cross-sectional study was conducted at the end of confinement in Spain. Changes in the frequency or quantity of consumption of different types of food and food-related behaviors were analyzed. Socioeconomic and health-related variables were also considered. To determine whether dietary changes were related to socioeconomic position (SEP), Poisson regression models with robust variance were estimated. Overall, there were some changes towards a healthier diet such as an increase in fruit consumption (38.9%) and a decrease in the consumption of soft drinks (49.8%), sweets and pastries (39.3%), and convenience foods (49.2%). Some changes, however, were related to less healthy behaviors, such as a more irregular pattern of meal distribution (39.9%) or an increase in snacking between meals (56.4%). Changes towards less healthy eating were also related to students’ SEP. The risk of worsening the diet was found to be 21% higher in adolescents from a more disadvantaged SEP. Future public policies could be adapted to avoid increasing nutritional and health inequalities.

    A wide range of animal species are susceptible to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Natural and/or experimental infections have been reported in pet, zoo, farmed and wild animals. Interestingly, some SARS-CoV-2 variants, such as B.1.1.7/Alpha, B.1.351/Beta, and B.1.1.529/Omicron, were demonstrated to infect some animal species not susceptible to classical viral variants. The present study aimed to elucidate if goats (Capra aegagrus hircus) are susceptible to the B.1.351/Beta variant. First, an in silico approach was used to predict the affinity between the receptor-binding domain of the spike protein of SARS-CoV-2 B.1.351/Beta variant and angiotensin-converting enzyme 2 from goats. Moreover, we performed an experimental inoculation with this variant in domestic goat and showed evidence of infection. SARS-CoV-2 was detected in nasal swabs and tissues by RT-qPCR and/or immunohistochemistry, and seroneutralisation was confirmed via ELISA and live virus neutralisation assays. However, the viral amount and tissue distribution suggest a low susceptibility of goats to the B.1.351/Beta variant. Therefore, although monitoring livestock is advisable, it is unlikely that goats play a role as SARS-CoV-2 reservoir species, and they are not useful surrogates to study SARS-CoV-2 infection in farmed animals.

    Emerging and re-emerging pathogens represent a substantial threat to public health, as demonstrated with numerous outbreaks over the past years, including the 2013-2016 outbreak of Ebola virus in western Africa. Coronaviruses are also a threat for humans, as evidenced in 2002/2003 with infection by the severe acute respiratory syndrome coronavirus (SARS-CoV), which caused more than 8000 human infections with 10% fatality rate in 37 countries. Ten years later, a novel human coronavirus (Middle East respiratory syndrome coronavirus, MERS-CoV), associated with severe pneumonia, arose in the Kingdom of Saudi Arabia. Until December 2016, MERS has accounted for more than 1800 cases and 35% fatality rate. Finding an animal model of disease is key to develop vaccines or antivirals against such emerging pathogens and to understand its pathogenesis. Knowledge of the potential role of domestic livestock and other animal species in the transmission of pathogens is of importance to understand the epidemiology of the disease. Little is known about MERS-CoV animal host range. In this paper, experimental data on potential hosts for MERS-CoV is reviewed. Advantages and limitations of different animal models are evaluated in relation to viral pathogenesis and transmission studies. Finally, the relevance of potential new target species is discussed.

    The COVID-19 pandemic has sharpened the inequalities in our societies. In Spain, we observed that the impact on schooling varied according to socioeconomic, gender and sociocultural variables. In this article, we present a case analysis illustrating the impact of the COVID-19 pandemic on schooling in early educational grades (ages 3–6), which leads us to focus on school-family relationship. First, we present some studies that show the inequalities in education during the lockdown period, the digital divide faced by both schools and families and how digital mediation impacts school-family relationships. Then we will introduce our study, which aims to explore the uses, potentials and limitations of an app intended to facilitate the relationship. Our study took place during September 2020-January 2021, when social restriction persisted. It took the form of a telematic ethnography in which we monitored the meetings of the Early Childhood Education teachers and their interaction with the families via an app-based communication tool. Results have allowed us to identify that most conversations are initiated by the school and their aim is to show families the classroom activities. We have also observed some advantages regarding the use of this app: communication can become more direct and immediate, and teachers have developed strategies to foster proximity in this relationship, as well as to respond inclusively to diversity. Regarding the challenges, we identified the lack of involvement of some families, the need to transform the roles played by families and children, and the difficulty to maintain personalized relationships This research was funded by the Spanish Ministry of Economy, Industry and Competitiveness (MINECO), the Spanish State Research Agency (AEI), and the European Regional Development Funds (European Union), grant number EDU2017-83363-R

    Introduction: The COVID-19 pandemic will give rise to long-term changes in neurological care, which are not easily predictable. Material and methods: A key informant survey was used to enquire about the changes expected in the specialty over the next 5 years. The survey was completed by heads of neurology departments with broad knowledge of the situation, having been active during the pandemic. Results: Despite a low level of consensus between participants, there was strong (85%) and moderate consensus (70%) about certain subjects, mainly the increase in precautions to be taken, the use of telemedicine and teleconsultations, the reduction of care provided in in-person consultations to avoid the presence of large numbers of people in waiting rooms, the development of remote training solutions, and the changes in monitoring visits during clinical trials. There was consensus that there would be no changes to the indication of complementary testing or neurological examination. Conclusion: The key informant survey identified the foreseeable changes in neurological care after the pandemic. Introducción: La pandemia de COVID-19 va a conllevar cambios en la asistencia neurológica, que no se pueden prever fácilmente a largo plazo. Material y métodos: A través de un modelo de informadores clave se busca el consenso de cómo va a ser la especialidad en un plazo de 5 años, siendo los encuestados jefes de servicio de neurología con conocimiento amplio de la situación al haber actuado durante la pandemia. Resultados: Aunque se obtiene un grado de acuerdo bajo entre los encuestados, sí se describen acuerdos por consenso a nivel mayor (85%) y menor (70%). Los principales acuerdos se refieren al incremento de precauciones, al uso de la telemedicina, al mantenimiento de las consultas telefónicas, a la reducción de asistencia a las consultas evitando que hayan salas de espera con un número alto de personas, al desarrollo de técnicas docentes no presenciales y a la adaptación en el desarrollo de ensayos clínicos en relación con la visita de los monitores. Sin embargo, no se acuerda que haya cambios en la indicación de exploraciones complementarias, ni en la propia exploración neurológica. Conclusión: El método de informadores clave ha permitido conocer qué cambios se pueden prever tras la pandemia.

    The communication industry in Colombia has promoted over the last decade a process of transformation and design of new proposals in both traditional media and digital natives, a range of operational strategies to distribute textual, sound, and visual formats through the social networks, adapting the content to the particularities and attributes of each one of them. The irruption of the implementation of the peace accords, the pandemic and citizen nonconformity taken to the streets have served to verify the real dimension of this reconfiguration, as well as its effectiveness in terms of credibility and scope in the face of an unprecedented scenario that has transformed the social and cultural interaction of citizens through technology. This research focuses on the response of Colombian journalistic agents to the demand for information during the period 2019, 2020 and 2021, from a mixed quantitative-descriptive methodology that allows identifying, quantifying, and assessing the relationship between newspapers, radio stations and television channels with the new platforms. The corpus of the study is made up of the publications on social networks of the Colombian media with the greatest circulation according to the Colombian Association for Media Research: two newspapers (El tiempo and El espectador), five radio stations (Caracol radio, W radio, Blu radio, RCN radio and La FM) and the news from the two television networks with the highest audience (Noticias Caracol and Noticias RCN). The results of the study show a reinforcement of the brand of the journalistic company as a reference for information and credibility, however, the current situation has not served to legitimize the role of journalists in social networks and has underlined the fragility of a media ecosystem highly exposed to polarization, manipulation, and mistrust. Resumen La industria de la comunicación en Colombia ha impulsado a lo largo de la última década un proceso de transformación y diseño de nuevas propuestas tanto en medios tradicionales como en nativos digitales, gama de estrategias operativas para distribuir formatos textuales, sonoros y visuales a través de las redes sociales, adaptando los contenidos a las particularidades y atributos de cada una de ellas. La irrupción de la implementación de los acuerdos de paz, la pandemia y el inconformismo ciudadano llevado a las calles han servido para constatar la dimensión real de esa reconfiguración, así como su efectividad en términos de credibilidad y alcance ante un escenario inédito que ha transformado la interacción social y cultural de los ciudadanos a través de la tecnología. Esta investigación centra su atención en la respuesta de los agentes periodísticos colombianos a la demanda de información durante el periodo 2019, 2020 y 2021, desde una metodología mixta cuantitativo-descriptiva que permite identificar, cuantificar y valorar la relación entre periódicos, emisoras de radio y canales de televisión con las nuevas plataformas. El corpus del estudio está compuesto por las publicaciones en redes sociales de los medios colombianos con mayor difusión según la Asociación Colombiana de Investigación de Medios: dos periódicos (El tiempo y El espectador), cinco cadenas de radio (Caracol radio, W radio, Blu radio, RCN radio y La FM) y los informativos de las dos cadenas televisivas de mayor audiencia (Noticias Caracol y Noticias RCN). Los resultados del estudio evidencian un refuerzo de la marca de la empresa periodística como referente de información y credibilidad, no obstante, la coyuntura del momento no ha servido para legitimar el papel de los periodistas en las redes sociales, y ha subrayado la fragilidad de un ecosistema mediático muy expuesto a la polarización, la manipulación y la desconfianza.

    Case summary A 6-year-old female neutered domestic shorthair cat from Cyprus was presented with multiple ulcerated skin nodules. Cytology and histopathology of the lesions revealed granulomatous dermatitis with intracytoplasmic organisms, consistent with amastigotes of Leishmania species. Biochemistry identified a mild hyperproteinaemia. Blood extraction and PCR detected Leishmania species, Hepatozoon species and ‘ Candidatus Mycoplasma haemominutum’ (CMhm) DNA. Subsequent sequencing identified Hepatozoon felis. Additionally, the rRNA internal transcribed spacer 1 locus of Leishmania infantum was partially sequenced and phylogeny showed it to cluster with species derived from dogs in Italy and Uzbekistan, and a human in France. Allopurinol treatment was administered for 6 months. Clinical signs resolved in the second month of treatment with no deterioration 8 months post-treatment cessation. Quantitative PCR and ELISA were used to monitor L infantum blood DNA and antibody levels. The cat had high L infantum DNA levels pretreatment that gradually declined during treatment but increased 8 months post-treatment cessation. Similarly, ELISA revealed high levels of antibodies pretreatment, which gradually declined during treatment and increased slightly 8 months post-treatment cessation. The cat remained PCR positive for CMhm and Hepatozoon species throughout the study. There was no clinical evidence of relapse 24 months post-treatment. Relevance and novel information To our knowledge, this is the first clinical report of a cat with leishmaniosis with H felis and CMhm coinfections. The high L infantum DNA levels post-treatment cessation might indicate that although the lesions had resolved, prolonged or an alternative treatment could have been considered.
