ABSTRACT
SARS-CoV-2 infection in the pediatric population usually mani-fests with mild symptoms;however, in patients with comorbidities, there may be a severe pulmonary compromise. We present the case of a 3-month-old patient with acute SARS-CoV-2 infection, with persistent respiratory symptoms up to 8 weeks after the initial infection, with a persistently positive PCR test, requiring several hospitalizations, supplemental oxygen, and even invasive mechanical ventilation. Clinical and radiological manifestations were found consistent with bronchiolitis obliterans associated with SARS-CoV-2 infection. An adequate clinical response was documented after starting first-line treatment for bronchiolitis obliterans with satisfactory evolution during follow-up to date, evidencing the importance of considering this association in clinical practice.Copyright © 2022, Sociedad Chilena de Infectologia.

ABSTRACT
In recent years, and accentuated by the health crisis, the consumption of content on online video platforms has increased as an alternative to traditional audiovisual media. Focusing on the Spanish context, this article explores the communications of science influencers on Twitch, the predominant videostreaming platform, popular with gamers, esports and various other forms of social media entertainment. The study conducted a content analysis of audiovisual texts generated by a sample of six of the most representative Twitch science communicators in Spain on the basis of a set of semiotic-discursive categories. The analysis identified the discursive strategies underlying the analyzed texts and identifies the particularities of a type of science communication that coexists within the media ecosystem with old media and official scientific sources. Specifically, the science communicators on Twitch opt for an audiovisual format based on the personality vlog, a form of speech characterized by a didactic expressive articulation, synchronous interaction with the user, and the use of a fun tone based on shared community codes. Despite being a new type of science communication, and the ephemeral nature of the broadcasts, the results of this study suggest that Twitch is an efficient vehicle for attracting the attention of young audiences to scientific content. The results also suggest that the influencers or content creators analyzed are committed to discourses based on informational quality and scientific rigor.
ABSTRACT
The migration of creators from other platforms and the emergence of new lines of content are contributing to the thematic diversification of Twitch.tv beyond its leadership in gaming. This article explores the potential for collaboration, education, and creation of live-streaming platforms by analyzing the online coworking experience of the JaimeAltozano 'working room' on Twitch, launched after the outbreak of the Covid-19 pandemic. An initiative that gathered 222,172 hours worked by the community in three months. Using a mixed methods research design, the experience was studied on the basis of quantitative data, 67 in-depth interviews with users and ethnographic techniques for content analysis. The results obtained in the three phases of the research process show that experiences like the JaimeAltozano 'working room' are useful virtual spaces for productivity. Based on these results, a map of the phenomenon was drawn using six key concepts: gamification, synchronicity, community, participation, free operability, and common atmosphere. In the face of the growing platformization of cultural goods, our research delves into the media reality of Twitch beyond videogaming to explore the possibilities of live-streaming for the digital community's media empowerment.
ABSTRACT
Data from adult studies show that COVID-19 is more severe in men than women. However, no data are available for the pediatric population. For this reason, we performed this study aiming to understand if sex influenced disease severity and outcomes in a large cohort of Latin-American children with COVID-19 and multisystem inflammatory syndrome (MIS-C). We found that a higher percentage of male children developed MIS-C (8.9% vs 5% in females) and died (1.2% and 0.4% in females), although on multivariate adjusted analyses the only statistically significant difference was found in need of hospitalization, with females less frequently admitted compared with boys (25.6% vs 35.4%). This data are preliminary and need further independent studies to better assess the role of sex. © 2021, Il Pensiero Scientifico Editore s.r.l.. All rights reserved.
ABSTRACT
Objective: We aimed to realize a verification of the performance of the rapid serological tests used in Risaralda department. Methods: Analytical, cross-sectional study. Serum samples from health workers in Pereira city, who had a clinical and epidemiological suspicion for SARS-CoV-2 were included. The processing and validation of the tests was carried out at Universidad Tecnológica de Pereira. Sensitivity and specificity of rapid IgM / IgG serological tests were calculated using RT-PCR as the gold standard test. Results: 144 samples of health professionals were included. Rapid serological tests useful to identify or rule out the presence of IgM and IgG antibodies, especially in symptomatic patients, in whom the onset of symptoms is longer than 11 days. Discussion: The use of rapid tests is increasing, not only due to the speed of their results, but also due to the low associated costs and the need to identify non-susceptible patients, who must prioritize their return to work activities in the community as part of the economic reactivation of Colombia. It is necessary to confirm the adequate performance of the test to increase the probability of an adequate classification before proceeding with the routine use of this test. © 2021 Asociacion Colombiana de Infectologia.
