RESUMO Este artigo propõe instaurar uma zona de indiscernibilidade entre os domínios da arte e da educação. Para tanto, confronta documentos relativos tanto à legislação como à pesquisa educacional, com alguns gestos executados pelo artista Nelson Leirner em uma situação de ambiência pedagógica, dando vulto ao problema da demanda por sentido. Evoca procedimentos analíticos operados em três textos de Michel Foucault. Sua companhia permite tomar a representação como uma operação que ultrapassaria o mero ato de representar como re-apresentar a verdade. Tal modo de tomar a representação, em viés performativo, conduz à forja do desterro como estratégia metodológica de investigação de práticas, em seus modos singulares de funcionamento e efeitos.

ABSTRACT This article proposes to establish a zone of indiscernibility between the domains of art and education. To do so, it confronts documents related to both legislation and educational research, with some gestures performed by the artist Nelson Leirner in a situation of pedagogical ambience, highlighting the problem of the demand for meaning. It evokes analytical procedures operated in three texts by Michel Foucault. His company allows taking representation as an operation that would go beyond the mere act of representing as re-presenting the truth. Such way of taking representation, in a performative one, leads to the forge of the exile as a methodological strategy for investigating practices, in their unique modes of operation and effects.

This study aimed to estimate prevalence of loneliness among older Brazilian adults over the first seven months of the COVID-19 pandemic and to identify the predictors of loneliness trajectories. Pre-pandemic data derived from face-to-face interviews of participants of the 2019-2020 Brazilian Longitudinal Study of Aging (ELSI-Brazil), which is a nationally representative study of community-dwelling individuals aged 50 years and over. Pandemic data were based on three rounds of telephone interviews among those participants, conducted from May to October 2020. Loneliness was measured by a single-item question, considering those who had at least two repeated measures. Explanatory variables included depression, living alone, leaving home in the last week, and virtual connectedness in the last month. Mixed-effects logistic regression was used to estimate odds ratios with their 95% confidence intervals (95%CI) and to investigate loneliness trajectories and their predictors. In total, 5,108 participants were included. The overall prevalence of loneliness in the pre-pandemic period was 33.1% (95%CI: 29.4-36.8), higher than the pandemic period (round 1: 23.6%, 95%CI: 20.6-26.9; round 2: 20.5%, 95%CI: 17.8-23.5; round 3: 20.6%, 95%CI: 17.1-24.6). A significant interaction (p ≤ 0.05) was evidenced only between depression and time; participants with depression showed a greater reduction in loneliness levels. Although loneliness levels in Brazil have decreased during the pandemic, this pattern is not present for all older adults. Individuals with depression had a more significant reduction, probably due to feeling closer to their social network members during the stay-at-home recommendations.

Este estudo teve como objetivo estimar a prevalência de solidão entre idosos brasileiros nos primeiros sete meses da pandemia de COVID-19 e identificar os preditores das trajetórias de solidão, usando dados pré-pandemia oriundos de entrevistas presenciais de participantes do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil) de 2019-2020, um estudo de representatividade nacional com residentes da comunidade com 50 anos ou mais. Os dados durante a pandemia foram coletados em três rodadas de entrevistas telefônicas com os participantes, realizadas de maio a outubro de 2020. A solidão foi medida por uma questão de item único, considerando os casos com pelo menos duas medidas repetidas. As variáveis explicativas incluíram depressão, morar sozinho, sair de casa na última semana e conexão virtual no último mês. A regressão logística de efeitos mistos foi utilizada para estimar as razões de chances com seus intervalos de 95% de confiança (IC95%) e investigar trajetórias de solidão e seus preditores. Foram incluídos 5.108 participantes. A prevalência global de solidão no período pré-pandemia foi de 33,1% (IC95%: 29,4-36,8), um valor superior ao período pandêmico (rodada 1: 23,6%, IC95%: 20,6-26,9; rodada 2: 20,5%, IC95%: 17,8-23,5; rodada 3: 20,6%, IC95%: 17,1-24,6). Uma interação significativa (p ≤ 0,05) foi encontrada apenas entre depressão e tempo; participantes com depressão apresentaram maior redução dos níveis de solidão. Embora os níveis de solidão no Brasil tenham diminuído durante a pandemia, esse padrão não se aplica a todos os idosos. Indivíduos com depressão tiveram uma redução mais significativa provavelmente por se sentirem mais próximos aos membros de suas redes sociais durante as recomendações de ficar em casa.

Este estudio tuvo como objetivo estimar la prevalencia de la soledad entre los adultos mayores brasileños durante los primeros siete meses de la pandemia de COVID-19 e identificar los predictores de las trayectorias de la soledad. Los datos prepandémicos proceden de entrevistas cara a cara de los participantes del Estudio Longitudinal Brasileño sobre el Envejecimiento (ELSI-Brasil) de 2019-2020, que es un estudio nacionalmente representativo de los habitantes de la comunidad de 50 años o más. Los datos de la pandemia se basaron en tres rondas de entrevistas telefónicas entre esos participantes, realizadas de mayo a octubre de 2020. La soledad se midió con una pregunta de un solo ítem, teniendo en cuenta los que tenían al menos dos indicativos repetidos. Las variables explicativas incluían la depresión, el hecho de vivir solo, salir de casa en la última semana y la conexión virtual en el último mes. Se utilizó una regresión logística de efectos mixtos para estimar las odds ratios con sus intervalos del 95% de confianza (IC95%) y para investigar las trayectorias de la soledad y sus predictores. Se incluyeron 5.108 participantes. La prevalencia global de la soledad en el periodo prepandémico fue del 33,1% (IC95%: 29,4-36,8), superior a la del periodo pandémico (ronda 1: 23,6%, IC95%: 20,6-26,9; ronda 2: 20,5%, IC95%: 17,8-23,5, ronda 3: 20,6; IC95%: 17,1-24,6). Sólo se evidenció una interacción significativa (p ≤ 0,05) entre la depresión y el tiempo; los participantes con depresión mostraron una mayor reducción de los niveles de soledad. Aunque los niveles de soledad en Brasil han disminuido durante la pandemia, este patrón no se da en todos los adultos mayores. Aquellos individuos con depresión tuvieron una reducción más significativa, probablemente debido a que se sintieron más cerca de los miembros de su red social durante las recomendaciones de quedarse en casa.

Resumo É objetivo deste estudo analisar elementos do pensamento trágico (Nietzsche, Rosset) presentes no conto "Terpsícore" de Machado de Assis e dimensionar suas implicações para o campo educacional. Conquanto o conto emerja do cotidiano de um casal dos baixos estratos sociais do fim do século XIX, resvala na tradução mítica da musa da dança e resgata uma orientação pedagógica de aprovação incondicional da vida, expressa pela afirmação do acaso, do espetáculo, da estética, da festa e do amor fati.

Abstract This paper aims at analyzing elements of tragic thought (Nietzsche, Rosset) present in "Terpsícore", a short story by Machado de Assis, and at discussing its implications for the field of education. Although the story is about the daily life of a lower social stratum nineteenth century couple, it conducts a translation of the mythical muse of dance and rescues a pedagogical orientation for a unconditional approval of life, expressed by the affirmation of fortuity, the spectacle, aesthetics, the feast and amor fati.

This population study, which evaluated two parasitological methods for the diagnosis of schistosomiasis mansoni, was performed in a low-transmission area in Pedra Preta, Montes Claros, Minas Gerais, Brazil. A total of 201 inhabitants of the rural area participated in this research. Four stool samples were obtained from all participants and analysed using the Kato-Katz method (18 slides) and a commercial test, the TF-Test®, which was performed quantitatively. The data were analysed to determine prevalence, the sensitivity of the diagnostic methods, the worm burden and the definition of the "gold standard", which was obtained by totalling the results of all samples examined using the Kato-Katz technique and the TF-Test®. The results showed that the prevalence obtained from the examination of one Kato-Katz slide (the methodology adopted by the Brazilian control programme) was 8% compared to 35.8% from the "gold standard", which was a 4.5-fold difference. This result indicates that the prevalence of schistosomiasis in so-called low-transmission areas is significantly underestimated.

In this transversal study, factors related to infection with and transmission of Schistosoma mansoni were explored. Based on stool examinations of two Kato-Katz smears of a single sample, the prevalences of schistosomiasis and geohelminths were established. In a multivariable analysis, sets of demographic, socio-economic and water contact pattern variables were tested for strength of relation with infection. Males presented a 3.39-times higher risk for infection than females. The age groups between 10-19 years and 20-30 years showed risks of infection 7.1- and 7.5-times higher, respectively, than the control age group between 0-10 years. Individuals practicing leisure activities had a 1.96-times higher risk than those without these activities. The malacological survey identified snails of the species Biomphalaria glabrata, Biomphalaria straminea and Biomphalaria tenagophila. Two exemplars of B. glabrata (0.53%) proved positive for S. mansoni. The socio-economic improvements observed in the locality suggest a protective and preventive effect towards infection with schistosomiasis, which requires further investigation with a longitudinal and more detailed study design. Considering our findings, a proposal for an integrated control program should be based on two pillars: one horizontal, which involves social empowerment and health education, and another more vertical, which delivers treatment and infrastructure improvements.

Studies on concomitant schistosomiasis and human and experimental malaria have shown a variation in the immunospecific response, as well as an increase in the severity of both parasitoses. In the present study, a murine co-infection model was used to determine the effects of a co-infection with Schistosoma mansoni and Plasmodium berghei on the protective immunity acquired by repeated malarial infections and subsequent curative treatment with chloroquine. Our results have demonstrated that, compared to an infection with P. berghei only, the co-infection increases the malarial parasitaemia and decreases the survival rate. Indeed, mice that were immunized by infection and treatment with drug displayed no mortality whereas co-infected mice showed a reduced protective efficacy of immunization against P. berghei (mortality > 60%). Interestingly, this high mortality rate was not associated with high levels of parasitaemia. Our findings support the idea of a suppressive effect of a Schistosoma co-infection on the anti-malarial protection by immunization. This result reveals a possible drawback of the development of anti-malarial vaccines, especially considering the wide endemic areas for both parasitoses.

Este relato mostra tratamento Ortodôntico efetuado em paciente portador de Classe II, Divisão 1, de Angle, com sobremordida profunda e agenesia do incisivo lateral superior esquerdo, em que o espaço foi fechado ortodonticamente e o canino ocupou o lugar do incisivo lateral. Os procedimentos adotados possibilitaram a obtenção de estética agradável e relação oclusal normal. A linha mediana não apresentou desvio ao término do tratamento e a discrepância vertical foi devidamente corrigida.

This case report demonstrates the orthodontic treatment of a patient who presented a Class II Division 1 malocclusion, deep overbite and congenitally absent maxillary left lateral incisor. The space was closed orthodontically and maxillary cuspid was positioned in the place of the maxillary lateral incisor. The treatment applied resulted in a pleasant esthetics and normal occlusal relationship. The midline was coincident at the end of treatment and vertical discrepancy was properly corrected.
