Abstract INTRODUCTION: This epidemiological household survey aimed to estimate the prevalence of the current and past SARS-CoV-2 infections in Ribeirão Preto, a municipality of southeast Brazil. METHODS: The survey was conducted in two phases using a clustered sampling scheme. The first phase spanned May 1-3 and involved 709 participants. The second phase spanned June 11-14, 2020, and involved 646 participants. RESULTS: During the first phase, RT-PCR performed on nasopharyngeal swabs was positive at 0.14%. The serological tests were positive in 1.27% of the patients during the first phase and 2.79% during the second phase. People living in households with more than five members had a prevalence of 10.83% (95%CI: 1.58-74.27) higher than those living alone or with someone other. Considering the proportion of the positive serological test results with sex and age adjustments, approximately 2.37% (95%CI: 1.32-3.42) of the population had been cumulatively infected by mid-June 2020, which is equivalent to 16,670 people (95%CI: 9,267-24,074). Considering that 68 deaths from the disease in the residents of the city had been confirmed as at the date of the second phase of the survey, the infection fatality rate was estimated to be 0.41% (95%CI: 0.28-0.73). Our results suggest that approximately 88% of the cases of SARS-CoV-2 infection at the time of the survey were not reported to the local epidemiological surveillance service. CONCLUSIONS: The findings of this study provide in-depth knowledge of the COVID-19 pandemic in Brazil and are helpful for the preventive and decision-making policies of public managers.

RESUMO Objetivo: Mensurar o grau de satisfação de profissionais de saúde quanto à usabilidade de um sistema de informação em saúde neonatal e identificar os fatores que podem influenciar na satisfação do usuário frente à usabilidade. Métodos: Estudo transversal e exploratório realizado com 50 profissionais de saúde integrantes dos centros da Rede Brasileira de Pesquisas Neonatais. Para avaliação da usabilidade foi utilizado o instrumento System Usability Scale entre fevereiro e março de 2017. Realizou-se a análise estatística descritiva e inferencial das variáveis coletadas, com a finalidade de descrever a amostra, quantificar o grau de satisfação dos usuários e identificar as variáveis associadas ao grau de satisfação do usuário em relação à usabilidade. Resultados: Da população avaliada, 75% era do sexo feminino, com idade média 52,8 anos, 58% com pós-graduação (doutorado); tempo médio da última formação de 17 anos; área de atuação em medicina (neonatologia), grau intermediário de conhecimento em informática e tempo de utilização média do sistema de 52 meses. Quanto à usabilidade, 94% avaliaram o sistema como “bom”, “excelente” ou “melhor impossível”. A usabilidade do sistema não foi associada a idade, sexo, escolaridade, profissão, área de atuação, nível de conhecimento em informática e tempo de uso do sistema. Conclusões: O grau de satisfação do usuário do sistema informatizado de saúde foi considerado bom. Não foram identificados fatores demográficos que influenciassem sua avaliação.

ABSTRACT Objective: To measure the level of satisfaction regarding the usability of a neonatal health information system and identify if demographic factors can influence the usability of a health information system. Methods: A cross-sectional, exploratory study was carried out with a convenience sample of 50 users of the Brazilian Neonatal Research Network. The instrument chosen for the usability evaluation was the System Usability Scale between February and March 2017. The statistical analysis of the collected variables was carried out in order to describe the sample, to quantify the level of satisfaction of the users and to identify the variables associated with the level of satisfaction. Results: The female gender represented 75% of the sample. The mean age was 52.8 years; 58% had a doctoral degree, average time of graduation was 17 years, with area of practice in medicine (neonatology), with intermediate knowledge in computer science (74%) and mean system use time of 52 months. Regarding usability, 94% rated the system as “good”, “excellent” or “better than imaginable”. The usability of the system was not associated with age, gender, education, profession, area of practice, knowledge in computer science and time of system use. Conclusion: The level of satisfaction of the computerized health system user was considered good. No demographic factors were associated with the satisfaction of the users.

RESUMO Neste artigo, apresento a ideia de que a História no Ensino Médio não é ensinável. Para sustentá-la, argumento que: 1) os acontecimentos históricos não são passíveis de ensinamento porque a res gestae é de natureza informativa e explicativa; 2) ensino pressupõe a apropriação de um conhecimento adaptável a outras circunstâncias, tempos e espaços, o que é impertinente no caso da História, dada a irrepetibilidade dos seus fenômenos. Para ilustrar meu argumento, analiso as expressões “consciência histórica”, do historiador Jörn Rüsen, e “pensar historicamente”, do autor de livro didático Mario Schmidt. A partir dessa análise, sustento que o que frequentemente denominamos ensino de História se traduz, em linhas gerais, a ensinamentos ético-morais e de elementos das teorias historiográficas. E, por fim, faço uma diferenciação entre ensino e aprendizagem, concluindo que, embora a História não seja “matéria” ensinável, podemos aprender muito com ela.

ABSTRACT In this article, I defend the idea that History in High School is not teachable. To support that statement, I argue the following: 1) historical events (res gestae) are informative and explanatory in nature, and therefore cannot be taught; 2) the concept of teaching presumes the appropriation of knowledge that can be adapted and applied to other circumstances, time and space, which is not the case of History, since events do not repeat themselves. To illustrate my point of view, I analyse the expressions “historical consciousness” by the historian Jörn Rüsen and “to think historically” by the textbook author Mario Schmidt. Based on that analysis, I argue that what we often call History teaching actually translates into ethical-moral teachings and into theoretical elements of historiography. Finally, I cover the distinction between teaching and learning, and conclude that although History is not a teachable “subject matter,” we can learn a great deal with it.

RESUMO Objetivo: Descrever a frequência de tabagismo ativo entre pacientes com asma e indivíduos sem asma, usando questionários padronizados e dosagem da cotinina urinária. Métodos: Estudo transversal realizado em Salvador (BA), com 1.341 indivíduos, sendo 498 com asma grave, 417 com asma leve/moderada e 426 sem asma. O tabagismo foi identificado por meio de autorrelato utilizando questionários e por mensuração da cotinina urinária. Para a comparação das variáveis estudadas, utilizaram-se os testes do qui-quadrado e de Kruskal-Wallis. Resultados: Dos 55 participantes (4,1%) que se declararam tabagistas atuais, 5, 17 e 33 eram dos grupos asma grave, asma leve/moderada e sem asma, respectivamente. Desses 55, 32 (58,2%) eram tabagistas diários e 23 (41,8%) eram tabagistas ocasionais. Observaram-se níveis elevados de cotinina urinária entre não fumantes autodeclarados e tabagistas pregressos, especialmente no grupo asma grave, o que sugere omissão do hábito atual de fumar. A carga tabágica entre os fumantes e a proporção de ex-tabagistas foram maiores no grupo asma grave do que no grupo asma leve/moderada. Conclusões: O tabagismo pregresso esteve associado à asma grave. Tabagismo atual também foi observado em alguns pacientes com asma grave e detectou-se omissão em alguns casos. A investigação de tabagismo deve ser meticulosa em pacientes com asma grave e a entrevista desses deve ser complementada por uma avaliação objetiva.

ABSTRACT Objective: To determine the frequency of active smoking among patients with asthma and individuals without asthma by self-report and urinary cotinine measurement. Methods: This was a cross-sectional study conducted in the city of Salvador, Brazil, and involving 1,341 individuals: 498 patients with severe asthma, 417 patients with mild-to-moderate asthma, and 426 individuals without asthma. Smoking status was determined by self-report (with the use of standardized questionnaires) and urinary cotinine measurement. The study variables were compared with the chi-square test and the Kruskal-Wallis test. Results: Of the sample as a whole, 55 (4.1%) reported being current smokers. Of those, 5 had severe asthma, 17 had mild-to-moderate asthma, and 33 had no asthma diagnosis. Of the 55 smokers, 32 (58.2%) were daily smokers and 23 (41.8%) were occasional smokers. Urinary cotinine levels were found to be high in self-reported nonsmokers and former smokers, especially among severe asthma patients, a finding that suggests patient nondisclosure of smoking status. Among smokers, a longer smoking history was found in patients with severe asthma when compared with those with mild-to-moderate asthma. In addition, the proportion of former smokers was higher among patients with severe asthma than among those with mild-to-moderate asthma. Conclusions: Former smoking is associated with severe asthma. Current smoking is observed in patients with severe asthma, and patient nondisclosure of smoking status occurs in some cases. Patients with severe asthma should be thoroughly screened for smoking, and findings should be complemented by objective testing.

RESUMO Objetivo: Avaliar a associação de fatores sociodemográficos, antropométricos e epidemiológicos com o resultado das mamografias de mulheres submetidas ao rastreamento. Métodos: Trata-se de um estudo transversal com dados obtidos por meio de entrevistas, avaliação antropométrica e mamografia de 600 mulheres entre 40 a 69 anos, atendidas no Departamento de Prevenção do Hospital de Câncer de Barretos, em 2014. Os resultados de tais exames nas categorias BI-RADS 1 e 2 foram agrupados e classificados neste estudo como achado mamográfico normal, e aqueles das categorias BI-RADS 3, 4A, 4B, 4C e 5 como achado mamográfico alterado. Na análise estatística, utilizou-se o teste t de Student para comparar as médias, bem como odds ratio (OR), com seus respectivos intervalos de confiança de 95% (IC95%), na verificação de associação por análise multivariada. Resultados: Das 600 mulheres avaliadas, 45% pertenciam à faixa etária dos 40 a 49 anos e 60,2% foram classificadas na categoria BI-RADS 2. Na análise multivariada, verificou-se que as mulheres com hipertensão arterial (OR: 2,64; IC95%: 1,07–6,49; p<0,05) apresentaram maiores chances de alteração na mamografia, enquanto que atividade física foi associada à menor chance (OR: 0,30; IC95%: 0,11–0,81; p<0,05). Conclusão: Mulheres hipertensas submetidas à mamografia de rastreamento tiveram maiores chances de apresentarem alterações mamográficas, ao passo que mulheres praticantes de atividade física apresentaram uma chance menor (70%) de terem alteração na mama em relação às sedentárias.

ABSTRACT Objective: To evaluate association of sociodemographic, anthropometric, and epidemiological factors with result of mammogram in women undergoing breast cancer screening. Methods: This is a cross-sectional study with data obtained through interviews, anthropometric measurements, and mammography of 600 women aged 40 to 69 years at the Preventive Medicine Department of Hospital de Câncer de Barretos, Brazil, in 2014. The results of these examinations in the BI-RADS categories 1 and 2 were grouped and classified in this study as normal mammogram outcome, and those of BI-RADS categories 3, 4A, 4B, 4C, and 5 were grouped and classified as altered mammogram outcome. The statistical analysis included the Student's t-test to compare means, as well as odds ratios (OR), with their corresponding 95% confidence intervals (95%CI), to verify an association by means of the multivariate analysis. Results: Of 600 women evaluated, 45% belonged to the age group of 40–49 years-old and 60.2% were classified as BI-RADS category 2. The multivariate analysis showed that women with blood hypertension (OR: 2.64; 95%CI: 1.07–6.49; p<0.05) were more likely to present changes in the mammography, while physical activity was associated with lower chances (OR: 0.30; 95%CI: 0.11–0.81; p<0.05). Conclusion: Hypertensive women undergoing screening mammography are more likely to present mammographic changes, whereas women practicing physical activity have lower chances (70%) of presenting changes in the breast compared with sedentary individuals.

Neste artigo apresenta-se a perspectiva do historiador e teórico da história, e a da literatura de Hayden White a respeito das utilidades e desvantagens que a história pode ter, por meio da historiografia, ao mundo contemporâneo, a partir de uma análise predominantemente interna de suas obras. Observa-se que a idéia norteadora do autor de Metahistory consiste em argumentar a favor da limitação epistêmica na construção do significado do discurso produzido pelos historiadores, o que possibilitaria o uso da história para auxiliar os homens do presente na resolução de determinados problemas.

This article investigated the perspective of the historian and literary theorist and historiographic Hayden White about the utilities and disadvantages that history can have the contemporary world through the historiography - from a predominantly internal analysis of his works. It was observed that the guiding idea of the author of Metahistory is to argue in favour of limiting epistemic of the speech produced by historians, which would allow the use of history to help the men of this in the resolution of certain problems.

O presente trabalho foi desenvolvido em casa de vegetação, na Estação Biológica da Universidade de Brasília, com objetivo de avaliar genótipos de maracujazeiro-amarelo frente ao fungo C. gloeosporioides, agente causal da antracnose. Para inoculação dos genótipos, utilizou-se uma suspensão contendo 5x10(6) esporos/mL do patógeno, depositados sobre ferimentos preestabelecidos com auxílio de escova de aço de cerdas finas. A primeira avaliação foi realizada 20 dias após a inoculação, e as demais, a intervalos de 7 dias, encerrando-se na sétima avaliação, aos 62 dias. Determinaram-se a incidência e a severidade da antracnose, com auxílio de uma escala graduada de notas, onde 1 = ausência de sintomas e 7 = desfolha. Consideraram-se as plantas como: Resistentes (R), com notas médias < 2; Moderadamente Resistentes (MR), com notas médias > 2 e < 3; Suscetíveis (S), com notas médias > 3 e < 4; e Altamente Suscetíveis (AS), com notas médias > 4. No geral, dois genótipos foram classificadas como Moderadamente Resistentes; oito, como Suscetíveis e 62, como Altamente Suscetíveis.

The present work was carried out in order to evaluate the resistance of passion fruit genotypes to C. gloeosporioides, the agent of anthracnose. C. gloeosporioides was inoculated in the lineages of passion fruit plants at a concentration of 5x10(6) spores on wounds pre-established by abrasion with a fine steel brush. The first evaluation was carried out 20 days after the inoculation and the others in intervals of seven days, ending in the seventh evaluation 62 days after the inoculation. To evaluate the degree of incidence and severity of anthracnose, a grade scale was established, where 1 = absence of symptoms and 7 = leaf loss. Average grades < 2 = Resistant (R); > 2 and < 3 = Moderately Resistant (MR); > 3 and < 4 = Susceptible (S) and > = Highly Susceptible (HS). In general, two genotypes were classified as Moderately Resistant; eight as Susceptible and sixty-two were highly Susceptible.
