1, 2, 3... TESTANDO! UMA EXPERIÊNCIA DE ANÁLISE DE ENQUADRAMENTO COM TELEJORNALISMO ESPORTIVO

O esporte vem ganhando espaço no jornalismo brasileiro, em virtude da realização de megaeventos no país. Nesse sentido, é relevante observar como os diversos meios definem, conforme seus projetos editoriais, os enfoques dados às informações que veiculam. O presente trabalho se apresenta como um exercício preliminar de aplicação metodológica, a partir do conceito de enquadramento, a um pequeno fato veiculado na mídia, relacionado com a Copa do Mundo FIFA 2014, escolhido pela coincidência da sua divulgação em três emissoras de televisão de sinal aberto: Record News, Globo e Bandeirantes. O fato em destaque foi o andamento das obras do estádio do Maracanã, no Rio de Janeiro, acompanhado entre os dias 14 e 21 de abril/2012. As matérias foram recolhidas, transcritas e analisadas conforme as categorias de seleção, exclusão e ênfase. Como considerações finais, é possível compreender que tal coincidência nas matérias teve o propósito de tranquilizar a população, especialmente a carioca, diante dos rumores, depois confirmados, da saída da construtora Delta do consórcio responsável pelas obras de reforma do Maracanã, dando garantias da conclusão das reformas (“modernização”) a tempo do estado do Rio de Janeiro receber a Copa das Confederações (2013) e a Copa do Mundo FIFA (2014), conforme previsto

Molecular epidemiological investigation of Mayaro virus in febrile patients from Goiania City, 2017-2018.

Mayaro virus (MAYV) has historically been associated with sylvatic transmission; however, urban outbreaks have been reported in Brazil, including cases of co-detection with dengue virus (DENV). Therefore, we performed a molecular survey to investigate MAYV circulation and cocirculation with DENV within Goiania, a major city in Central-West Brazil. Among 375 subjects with arbovirus-like symptoms, 259 were positive for DENV and 26 for MAYV. Of these, 17 were coinfected with DENV-2, suggesting co-transmission of the viruses. The most common complaints at the time of inclusion were myalgia, headache, fever, arthralgia, retro-orbital pain, and skin rash. No specific symptoms were associated with MAYV when either detected alone or co-detected with DENV, compared to that when DENV was detected alone. Most MAYV-infected subjects were women with no recent travel history to rural/sylvatic areas. Phylogenetic reconstruction indicated that the MAYV identified in this study is closely related with a lineage observed in Peru, belonging to genotype D. Our results corroborate the growing circulation of MAYV in urban environments in Brazil and reinforce the need to implement laboratory diagnosis in the Unified Health System, considering that the clinical manifestations of Mayaro fever are similar to those of other arboviruses, particularly dengue. Furthermore, most cases occurred in association with DENV-2. Further phylogenetic studies are needed to evaluate MAYV, which has not been widely examined

Síndrome de Mccleery: Mccleery Syndrome

Introdução: A Síndrome de Mccleery foi descrita detalhadamente a primeira vez em 1951, por Mccleery. É um subtipo da Síndrome do Desfiladeiro Torácico, causada pela obstrução não trombótica da veia subclávia, em que acomete adultos jovens (principalmente do sexo masculino) e atletas, em razão dos esforços repetitivos e da hipertrofia muscular da região torácica. Apresentação do caso: Paciente sexo masculino, 25 anos, atleta, apresenta quadro de dor intensa de início súbito em membro superior direito, seguida de edema e cianose. Relata piora do quadro ao movimentar o membro e melhora parcial com uso de analgésicos e repouso. A ultrassonografia com Doppler identifica compressão de veia subclávia. Realizada venografia que apresentou obstrução de veia subclávia no espaço costoclavicular. Discussão: Nesta síndrome, o espaço costoclavicular, especificamente, ganha destaque. Delimitado entre a primeira costela e a clavícula, onde passam os vasos subclávios e o plexo braquial. Seu diagnóstico é clínico, contudo deve ser associado a exames de imagem. O tratamento é direcionado de acordo com a etiologia e a presença ou não de complicações. Frequentemente a conduta inicial é o tratamento clínico, procurando aliviar os sintomas. No entanto, estudiosos vêm advogando intervenções cirúrgicas precoces, no intuito de evitar eventos trombóticos, limitações funcionais e restrições de mobilidade. Conclusão: O presente relato de caso faz-se importante como contribuição para o literatura  científica, de forma que haja melhor acesso e maior discussão acerca do tema nas plataformas acadêmicas

COVID-19 outcomes in people living with HIV: Peering through the waves

Objective: To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods: This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results: Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions: Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group

Pineocitoma causando Hidrocefalia: Pineocytoma causing Hydrocephalus

Introdução: O Pineocitoma é um tumor do sistema nervoso central de caráter benigno. Esse tipo histológico é infrequente correspondendo menos de 1% dos tumores intracranianos. A clínica apresenta desde hipertensão intracraniana até compressão de estruturas nervosas, associado a uma altíssima taxa de morbidade e mortalidade. Apresentação do caso: Paciente com 23anos, sexo feminino, procurou serviço de emergência médica referindo cefaleia intensa de escala de dor 8/10, sem fatores precipitantes e sem melhora com uso de analgésicos ou anti-inflamatório, negou comorbidades e uso de medicações contínuas. Apresenta-se com muita dor, administrando medicação endovenosa para melhorar os sintomas. Foi solicitada uma Tomografia de crânio que evidenciou uma lesão sugestiva de meningioma, paciente foi internada e conduzida para cirurgia para retirada da lesão a qual foi constatada no histopatológico que se tratava de um Pineocitoma. Discussão: o diagnóstico é baseado na clínica, exames de neuroimagem, marcadores tumorais no líquor cefalorraquidiano, o histopatológico já é um exame definitivo, com a tomografia computadorizada de crânio é possível visualizar, massa com contorno bem delimitado, em torno de 3 cm de diâmetro, sendo possível encontrar hidrocefalia associada. O tratamento padrão ouro é ressecção cirúrgica completa, associando a radioterapia e quimioterapia. Conclusão: o tratamento mostra resultado de cura, visto que o Pineocitoma raramente evolui para metástase, resultando em um bom prognóstico devido a evolução tecnológica em tratamento e métodos diagnósticos

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

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.
