Narrando a história atual: a construção da imagem dos grupos sociais em conflito nas manifestações de junho de 2013 no Brasil

The present paper aims at analyzing the representation of social groups involved in the protests in June 2013, in Brazil, trough the study of categories of mental model of events, as van Dijk – in case, participants and his actions – in media narratives. Through this analysis, the study aims to understand how the representation of these groups contributes or not to the credibility of the protests and to build the image of the groups involved in the conflict. Within the theoretical framework of Critical Discourse Analysis (ACD), proposed by van Dijk, this article aims to investigate the discursive function of media narratives in the construction of image of these groups in the following magazines: Veja, Isto É, Época and Carta Capital.

Abordagens multidisciplinares no manejo da Endometriose: integrando abordagens cirúrgicas e farmacológicas para um tratamento efetivo

A endometriose é uma doença ginecológica crônica caracterizada pelo crescimento anormal de tecido semelhante ao endométrio fora do útero. O manejo efetivo dessa condição complexa requer uma abordagem integrada e multidisciplinar, que combina intervenções cirúrgicas, terapias farmacológicas, terapias complementares e modificações no estilo de vida. A cirurgia é frequentemente realizada para remover as lesões endometrióticas visíveis, enquanto a terapia farmacológica busca suprimir a atividade hormonal e controlar a dor. Terapias complementares, como acupuntura e fisioterapia, podem auxiliar no alívio dos sintomas, e a adoção de um estilo de vida saudável pode contribuir para o bem-estar geral. A integração dessas abordagens permite um cuidado personalizado e abrangente, considerando a gravidade da doença, os objetivos reprodutivos e as preferências individuais das pacientes. A colaboração entre profissionais de saúde especializados e a participação ativa das pacientes são essenciais para um tratamento efetivo. Apesar dos avanços alcançados, ainda há lacunas de conhecimento e desafios a serem enfrentados, destacando a necessidade de pesquisas futuras para aprimorar o manejo da endometriose

High anti-SARS-CoV-2 antibody seroconversion rates before the second wave in Manaus, Brazil, and the protective effect of social behaviour measures: results from the prospective DETECTCoV-19 cohort

Background: The city of Manaus, Brazil, has seen two collapses of the health system due to the COVID-19 pandemic. We report anti-SARS-CoV-2 nucleocapsid IgG antibody seroconversion rates and associated risk factors in Manaus residents before the second wave of the epidemic in Brazil. Methods: A convenience sample of adult (aged ≥18 years) residents of Manaus was recruited through online and university website advertising into the DETECTCoV-19 study cohort. The current analysis of seroconversion included a subgroup of DETECTCoV-19 participants who had at least two serum sample collections separated by at least 4 weeks between Aug 19 and Oct 2, 2020 (visit 1), and Oct 19 and Nov 27, 2020 (visit 2). Those who reported (or had no data on) having a COVID-19 diagnosis before visit 1, and who were positive for anti-SARS-CoV-2 nucleocapsid IgG antibodies at visit 1 were excluded. Using an in-house ELISA, the reactivity index (RI; calculated as the optical density ratio of the sample to the negative control) for serum anti-SARS-CoV-2 nucleocapsid IgG antibodies was measured at both visits. We calculated the incidence of seroconversion (defined as RI values ≤1·5 at visit 1 and ≥1·5 at visit 2, and a ratio >2 between the visit 2 and visit 1 RI values) during the study period, as well as incidence rate ratios (IRRs) through cluster-corrected and adjusted Poisson regression models to analyse associations between seroconversion and variables related to sociodemographic characteristics, health access, comorbidities, COVID-19 exposure, protective behaviours, and symptoms. Findings: 2496 DETECTCoV-19 cohort participants returned for a follow-up visit between Oct 19 and Nov 27, 2020, of whom 204 reported having COVID-19 before the first visit and 24 had no data regarding previous disease status. 559 participants were seropositive for anti-SARS-CoV-2 nucleocapsid IgG antibodies at baseline. Of the remaining 1709 participants who were seronegative at baseline, 71 did not meet the criteria for seroconversion and were excluded from the analyses. Among the remaining 1638 participants who were seronegative at baseline, 214 showed seroconversion at visit 2. The seroconversion incidence was 13·06% (95% CI 11·52–14·79) overall and 6·78% (5·61–8·10) for symptomatic seroconversion, over a median follow-up period of 57 days (IQR 54–61). 48·1% of seroconversion events were estimated to be asymptomatic. The sample had higher proportions of affluent and higher-educated people than those reported for the Manaus city population. In the fully adjusted and corrected model, risk factors for seroconversion before visit 2 were having a COVID-19 case in the household (IRR 1·49 [95% CI 1·21–1·83]), not wearing a mask during contact with a person with COVID-19 (1·25 [1·09–1·45]), relaxation of physical distancing (1·31 [1·05–1·64]), and having flu-like symptoms (1·79 [1·23–2·59]) or a COVID-19 diagnosis (3·57 [2·27–5·63]) between the first and second visits, whereas working remotely was associated with lower incidence (0·74 [0·56–0·97]). Interpretation: An intense infection transmission period preceded the second wave of COVID-19 in Manaus. Several modifiable behaviours increased the risk of seroconversion, including non-compliance with non-pharmaceutical interventions measures such as not wearing a mask during contact, relaxation of protective measures, and non-remote working. Increased testing in high-transmission areas is needed to provide timely information about ongoing transmission and aid appropriate implementation of transmission mitigation measures.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Narrating the current history: The image building of social groups in conflict in the protests of June 2013 in Brazil

O presente trabalho tem por objetivo analisar, por meio de categorias dos modelos mentais de evento, conforme van Dijk – no caso, participantes e ações –, como os grupos sociais envolvidos nos protestos, ocorridos em junho de 2013, no Brasil, são representados nas narrativas midiáticas e como essa representação contribui ou não para a credibilidade desses protestos e, consequentemente, para a construção da imagem dos grupos envolvidos no conflito. Para sua realização, filiamo-nos ao quadro teórico da Análise Crítica do Discurso (ACD), proposto por van Dijk, com o objetivo de compreender o funcionamento discursivo das narrativas midiáticas na construção da imagem desses grupos, nas seguintes revistas semanais de informação: Veja, Isto É, Época e Carta Capital.

Prevalence of errors causing events allegedly attributable to vaccination/immunization: systematic review and meta-analysis

ABSTRACT Objective: To identify the prevalence of errors that caused events supposedly attributable to vaccination or immunization. Method: Systematic literature review with meta-analysis carried out on the Medline, Cochrane Library, Cinahl, Web of Science, Lilacs, Scopus; Embase; Open Grey; Google Scholar; and Grey Lit databases; with studies that presented the prevalence of immunization errors that caused events or that provided data that allowed this indicator to be calculated. Results: We evaluated 11 articles published between 2010 and 2021, indicating a prevalence of 0.044 errors per 10,000 doses administered (n=762; CI95%: 0.026 - 0.075; I2 = 99%, p < 0.01). The prevalence was higher in children under 5 (0.334 / 10,000 doses; n=14). The predominant events were fever, local pain, edema and redness. Conclusion: A low prevalence of errors causing events was identified. However, events supposedly attributable to vaccination or immunization can contribute to vaccine hesitancy and, consequently, have an impact on vaccination coverage
