Abstract Transgender people are exposed to different situations of vulnerability that intersect, having negative impacts on the health-illness-care process. To better understand this issue, we sought to know the experiences of seven transgender undergraduates at a public university in Minas Gerais, from semi-structured interviews. The narratives were analyzed on the perspective of content analysis, and the final categories juxtaposed with studies of social sciences and public health. In general, the narratives are different from those which account for most of the research on the theme in Brazil, especially regarding maintaining family bonds and the access to public universities. Hence, we formulated the hypothesis that the interaction between these elements and other markers of differences can positively contribute to establishing alliances and strategies to deal with the regime of gender identity intelligibility and the constraints of access to education, work, and health. Understanding these dynamics and their limitations, under the perspective in which the individual and the collective are intertwined, enabled us to highlight the role of (hetero)normativity in the segregation processes of transgender people, as well as reflecting on the political actions that might effectively transform this social reality. intersect healthillnesscare health illness care process issue Gerais semistructured semi structured interviews analysis general Brazil universities Hence education work limitations intertwined heteronormativity hetero normativity reality

Resumo As pessoas trans estão expostas a diferentes situações de vulnerabilidade que se entrecruzam, causando impactos negativos no processo saúde-doença-cuidado. Para melhor compreender essa questão, buscamos conhecer as experiências de sete estudantes trans de uma universidade pública de Minas Gerais, a partir de entrevistas norteadas por roteiro semiestruturado. As falas foram analisadas pela perspectiva da análise de conteúdo, e as categorias finais foram tensionadas com estudos das ciências sociais e da saúde coletiva. De forma geral, as narrativas se diferenciaram daquelas que compõem a maioria das pesquisas sobre o tema no Brasil, sobretudo em relação à manutenção de vínculos familiares e ao acesso à universidade pública. Nesse sentido, formulamos a hipótese de que a interação desses elementos com outros marcadores de diferenças pode contribuir positivamente para o estabelecimento de alianças e estratégias, a fim de lidar com o regime de inteligibilidade das identidades de gênero e com as dificuldades de acesso à educação, ao trabalho e à saúde. Compreender essa dinâmica e suas limitações, em uma perspectiva em que o individual se enlaça ao coletivo, possibilitou evidenciar o funcionamento da (hétero)normatividade nos processos de segregação de pessoas trans, assim como refletir sobre ações políticas que possam transformar essa realidade social efetivamente. entrecruzam saúdedoençacuidado. saúdedoençacuidado doença cuidado. cuidado saúde-doença-cuidado questão Gerais semiestruturado conteúdo coletiva geral Brasil sentido estratégias educação limitações coletivo héteronormatividade hétero normatividade efetivamente

Trata-se de uma estratégia de ensino construída e utilizada como disparador para a temática sobre Instituições Totais e o hospital psiquiátrico como dispositivo de segregação e degradação da identidade dos internos.

This article discusses a teaching strategy developed as a trigger for the theme of total institutions and psychiatric hospitals as devices for segregating and degrading the identity of inpatients. Based on an ethnographic record and political and paradigmatic shifts in mental health care, we created a chronicle highlighting the main concepts of Erving Goffman’s symbolic interactionism. This text invites readers to traverse the various layers that drive the institution’s cogs and wheels and produce the moral career of the mentally ill and staff who work there. Processes in which the mortification and profanation of the Self are shrouded by an official knowledge that controls, punishes and reacts to anything that threatens the asylum apparatus with destabilization.

Abstract Background: Patients using immunosuppressive drugs may have unfavorable results after infections. However, there is a lack of information regarding COVID 19 in these patients, especially in patients with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the risk factors associated with COVID 19 hospitalizations in patients with RA. Methods: This multicenter, prospective cohort study is within the ReumaCoV Brazil registry and included 489 patients with RA. In this context, 269 patients who tested positive for COVID 19 were compared to 220 patients who tested negative for COVID 19 (control group). All patient data were collected from the Research Electronic Data Capture database. Results: The participants were predominantly female (90.6%) with a mean age of 53 ±12 years. Of the patients with COVID 19, 54 (20.1%) required hospitalization. After multiple adjustments, the final regression model showed that heart disease (OR =4.61, 95% CI 1.06–20.02. P < 0.001) and current use of glucocorticoids (OR =20.66, 95% CI 3.09–138. P < 0.002) were the risk factors associated with hospitalization. In addition, anosmia was associated with a lower chance of hospitalization (OR =0.26; 95% CI 0.10–0.67, P < 0.005). Conclusion: Our results demonstrated that heart disease and the use of glucocorticoids were associated with a higher number of hospital admissions for COVID 19 in patients with RA.

ABSTRACT. Strawberries are berry-type fruits that are very popular and widely consumed all over the world. The sensorial, physical-chemical and nutritional characteristics of strawberries are parameters of quality that influence the choices of consumers. However, these characteristics may be influenced by intrinsic and extrinsic factors that alter the fruit quality. The concentrations of nutrients and other chemical compounds in strawberries may increase and/or decrease according to the cropping system, maturation stage, climatic conditions, and preservation and storage methods. Factors characteristic of the cultivar, such as the genetic profile, may also influence the composition of strawberries. In this context, the objective of this research was to evaluate the sensorial, physical-chemical and nutritional characteristics of different strawberry cultivars to identify the genotype(s) with the best characteristics for commercialization and human consumption. The day-neutral strawberry cultivar "Aromas" and short-day strawberry cultivars "Camarosa, Camino Real, Dover, Sweet Charlie, and Tudla" were cultivated in the Olericultura Sector of the State University of the Midwest (UNICENTRO), Paraná State, Brazil. The fruits were characterized in relation to their physical-chemical, nutritional and sensorial aspects. According to the sensorial profiles, the Camarosa, Camino Real, Dover, and Tudla genotypes showed greater acceptability among consumers. Camarosa, Sweet Charlie, and Tudla presented better physical-chemical characteristics for human consumption, while the cultivars Camarosa, Dover, and Tudla had the best nutritional contents. In general, it is concluded that the genotypes Camarosa and Tudla are the most favourable for human consumption, according to their sensorial, physical-chemical and nutritional characteristics.

Resumo: Introdução: A síndrome de burnout causa repercussão com impactos individuais, sociais e econômicos. A tríade que representa a síndrome acomete milhões de trabalhadores pelo mundo, incluindo os trabalhadores da área da saúde e, entre eles, os médicos. Pesquisas apontam um incremento das taxas de burnout entre médicos e residentes, mas pouco se fala sobre a síndrome em estudantes de Medicina. Objetivo: Ao observarmos o adoecimento constante de estudantes, identificamos a necessidade de compreender mecanismos que possam ser considerados disparadores. Assim, investigamos a percepção dos estudantes de Medicina que cursam o estágio supervisionado sobre a síndrome de burnout e a autoidentificação dos sintomas. Método: Realizamos pesquisa qualitativa do tipo estudo de caso utilizando grupo focal como ferramenta metodológica. Participaram desta pesquisa 22 internos divididos em três grupos focais. As falas foram analisadas segundo a análise de conteúdo. Resultados: Dessas análises e de suas inferências, delinearam-se quatro categorias: “(Con)fusão de papéis: o processo de deixar de ser estudante”; “Uma síndrome (in)visível: a banalização do sofrimento”; “Tornar-se médico: forjado no sofrimento”; “(Des)identificação: efeitos de um processo nada fácil”. Conclusão: Os estudantes desconheciam a síndrome e não foram capazes de reconhecer os sintomas dela durante a formação. O achado significativo apontou para a sobrecarga relacionada à falta de tempo e como esta gera um processo de sofrimento nos estudantes. Acredita-se, portanto, que o processo de ensino precisa ser repensado para que os estudantes possam, de fato, aprender e apreender todos os significados que a universidade tem potencialmente a lhes oferecer.

Abstract: Introduction: Burnout syndrome has individual, social and economic impacts. The triad that represents the syndrome affects millions of workers around the world, including healthcare workers and, among them, doctors. Research points to an increase in burnout rates among doctors and residents, but little is said about the syndrome in medical students. Objective: By observing students constantly falling ill, we identified the need to understand mechanisms that can be considered triggers. Thus, we investigated how medical interns viewed Burnout Syndrome and the self-identification of symptoms. Method: We carried out qualitative case study research using a focus group as a methodological tool. Twenty-two medical students participated in this study, divided into 3 focus groups. The statements were submitted to Content Analysis. Results: From these analyses and their inferences, four categories were outlined: ‘(Con)fusion of roles: the process of ceasing to be a student’; ‘A (in)visible syndrome: the trivialization of suffering’; ‘Becoming a doctor: forged in suffering’; ‘(Mis)identification: effects of a far from easy process’. Conclusion: Students were unaware of the syndrome and were unable to recognize its symptoms during training. The significant finding pointed to the burden related to lack of time and how it generates a process of suffering in students. Thus, it is believed that the teaching process needs to be rethought so that students can, in fact, learn and grasp all the meanings that the University potentially has to offer.

Resumo: Introdução: O curso de Medicina da Universidade Federal do Triângulo Mineiro (UFTM) foi criado em 1954. Em 2011, ocorreu a inclusão dos estágios supervisionados em medicina geral e comunitária I e II no internato, que inseriu os estudantes na rede de serviços da atenção básica do município, processo marcado por conflitos e limitações. Visando solucionar os impasses criados, a UFTM contratou, por meio de concurso público, preceptores de medicina de família e comunidade para atuar na rede municipal. Objetivo: Este estudo teve como objetivo analisar o arranjo institucional proposto para otimizar a relação ensino-serviço nos estágios supervisionados da área de medicina de família e comunidade, a partir da percepção de docentes e preceptores do Departamento de Saúde Coletiva que atuam na atenção primária. Método: Trata-se de estudo de caso apoiado em pesquisa documental e entrevistas realizadas com três docentes e três preceptores do curso de Medicina de uma instituição pública. Resultado: A análise temática revelou três núcleos que foram agrupados nas categorias “contexto difícil”, “desencontro de expectativas” e “fios soltos”. O “contexto difícil” exigia a negociação e o deslocamento de poder entre as instituições e seus agentes. A (con)fusão entre os papéis de docente e preceptor produziu “desencontro de expectativas”. Em “fios soltos”, a lacuna entre a universidade e a rede municipal parece intransponível e reiterada a partir do concurso. Conclusão: A realização do concurso e a contratação de preceptores não foram suficientes para superar os desafios da articulação entre a universidade e a rede municipal de saúde. A pesquisa demonstra que não existe caminho simples para a integração ensino-serviço e que a interdependência dos atores aponta para o desafio e a necessidade da construção de agendas e espaços de decisão coletivos.

Abstract: Introduction: The Medical course at the Federal University of the Triângulo Mineiro (UFTM) was created in 1954. In 2011, the Supervised Internships in General and Community Medicine I and II were included in the clerkship program, which immersed students in the local Primary Care network - a process marked by conflicts and limitations. Aiming to solve the impasses created, UFTM hired, through a public tender, Family and Community Medicine preceptors to work in the municipal network. Objective: To analyze the institutional arrangement proposed to optimize the teaching-service relationship in supervised clerkships in the area of Family and Community Medicine, from the perception of teachers and preceptors of the Department of Public Health who work in Primary Care. Method: Case study supported by documentary research and interviews with three professors and three preceptors from the medical school of a public institution. Result: Thematic content analysis revealed three core aspects that were grouped into the categories: “Difficult setting”; “Mismatch of expectations”; and “Loose threads”. The “Difficult setting” demanded negotiation and a power shift between institutions and their agents. The (con)fusion between the roles of teacher and preceptor produced “Mismatches of expectations”. In “Loose Threads,” the gap between the university and the municipal network seems insurmountable and reiterated was after the public tender. Conclusion: The public tender process and hiring of preceptors proved insufficient to overcome the challenges of connectivity between the university and the municipal health network. The research shows that there is no simple way to integrate teaching-service and that the interdependence of the actors points to the challenge and the need to build agendas and collective decision spaces.

Resumo Entendemos a ética em pesquisa como uma ação cotidiana de construção de confiança, afetada pelo compromisso de transformação de nossas práticas sociais. Este artigo tem por objetivo analisar as relações entre pesquisador-diretor e protagonista no processo de decisão sobre as imagens produzidas e incluídas no filme que narra a história de vida de Keila Simpson entrecruzada ao movimento social de travestis. Para além de uma dimensão estritamente estética, tal processo de decisão implicou negociação permanente entre ambos em um trabalho ético que ultrapassou a busca de sigilo, anonimato ou autorização formal. Os diálogos sobre a publicização de cenas relativas à intimidade da protagonista e suas relações com a família e a prostituição redimensionaram seu caráter privado e explicitaram as implicações políticas das formas de mostrar/ver as vidas travestis. É nesse esforço de incorporar os desafios éticos, como elementos estruturais da pesquisa, que se aponta para uma possibilidade de produção acadêmica comprometida em compartilhar lugares de pensar/fazer com os sujeitos pesquisados.

Abstract We understand research ethics as daily actions under taken to build trust, which are affected by a commitment to transform our social practices. The objective of this article is to analyze the relationship between a researcher/film director and the film’s protagonist when making decisions about images produced and included in a film about the life story of Keila Simpson and the social movement of transvestites. In addition to a strictly aesthetic dimension, this decision-making process involved permanent negotiations between the two in an ethical undertaking that went beyond an effort to maintain secrecy, anonymity or formal authorization. The dialogues about the release of scenes related to the private life of the protagonist and her relationships with family and prostitution redefined her private life and made explicit the political implications of forms of depicting and seeing the lives of transvestites. It is this effort to incorporate ethical challenges, as structural elements of research, that reveals the opportunity for academic production that is committed to sharing the thinking and doing with research subjects.

RESUMO As conquistas dos movimentos de lésbicas, gays, bissexuais, travestis e transexuais (LGBT) estabeleceram uma tensão na sociedade que sugere serem irreversíveis suas conquistas, inclusive em termos de visibilidade e recusa ao silenciamento. O cenário de redemocratização e a luta contra o preconceito e a discriminação, assim como pelos direitos humanos e acesso à saúde para todos, compõem alguns dos objetivos desses movimentos. Entretanto, a ideia ainda recorrente da impureza da homossexualidade, que posiciona o sujeito gay como “ser perigoso” reatualiza o estigma e a discriminação com base na suposta “contaminação presumida” do HIV/aids. Nesse sentido, o presente artigo tem por objetivo analisar os efeitos dos discursos sobre as (homo)sexualidades e o HIV/aids na formação médica. Por meio da autoetnografia performática, foi desenvolvida uma análise nas intersecções do self nos coletivos, do eu nas culturas, do agente nas agências, a partir de cenas (auto)etnográficas e da observação participante nos vários cenários de ensino-aprendizagem de uma escola médica pública brasileira. Observamos que, embora proscrito desde a CID 10, o diagnóstico de “homossexualismo” segue sendo produzido e produzindo efeitos por meio da solicitação sistemática e sem evidências de investigação do HIV/aids na formação médica. Assim, compreendemos que ainda há certa cultura hegemônica heterossexual-homofóbica na formação e no cuidado em saúde que atualiza o circuito da exclusão, dominação, colonização e subjugação do sujeito homossexual pela reiterada relação “ser gay – ter HIV/aids”. Com os encontros e as experiências vividas aqui analisadas, explicitam-se visceralmente as disputas e os enfrentamentos no currículo, na esfera do cotidiano e em nossa própria consciência e prática diária para a produção de espaços que considerem outras possibilidades de existência para além da somente hegemônica heterossexualidade branca masculina. Concluímos, também, que foram e ainda continuam sendo abertas várias disputas na formação e atuação médicas, evidenciando que “não estamos sozinhos”. Muitos(as) de nós estamos comprometidos(as) com a tentativa de construir outros modos de ensinar e cuidar, guiados por performances – escritas e corporificadas – de inclusão e resistência, cujo objetivo é expor, desafiar e transformar narrativas desumanas contra a população LGBT e a opressão em geral.

ABSTRACT The achievements of the lesbian, gay, bisexual, transvestite and transsexual (LGBT) movements have established a tension in society that suggests that their accomplishments are irreversible, including in terms of visibility and refusal to remain silent. The scenario of re-democratization and the fight against prejudice and discrimination, as well as human rights and access to health for all, make up some of the objectives of these movements. However, the persistently recurrent idea of the dirtiness of homosexuality that positions the gay subject as being dangerous, reaffirm the stigma and discrimination from the alleged “presumed contamination” of HIV/aids. In this sense, this article aims to analyze the effects of discourses on (homo)sexualities and HIV/aids in Medical Education. By means of performative autoethnography, an analysis was performed at the intersections of the “self” in the collective, the self in the cultures, from (auto)ethnographic scenes and participant observation in the various teaching scenarios of a Brazilian public Medical School. We observed that, although proscribed since ICD 10, the diagnosis of “homosexualism” continues to be produced through the systematic and unproven application of HIV/aids research in medical education. Thus, we understand that there is still a certain heterosexual-homophobic hegemonic culture in health education and health care that updates the circuit of exclusion, domination, colonization and subjugation of the homosexual subject by the repeated relationship between “being gay – having HIV/aids”. With the encounters and experiences that have been analyzed here, the disputes and confrontations in the curriculum, in the daily life and in our own daily consciousness and practice for the production of spaces that consider other ways of living beyond just hegemonic male white heterosexuality are made viscerally explicit. We also conclude that several disputes have been and are still being opened in medical training and performance, proving that “we are not alone”. Many of us are committed to the attempt to construct other ways of teaching and caring, guided by performances – written and embodied – of inclusion and resistance, whose goal is to expose, challenge and transform dehumanizing narratives against the LGBT population and oppression in general.

Binding between bovine serum albumin (BSA) and a plumeran indole alkaloid (PIA) isolated from the stem bark of Aspidosperma cylindrocarpon (Apocynaceae) was studied by spectroscopic techniques (UV-Vis absorption, circular dichroism, steady state and time-resolved fluorescence), combined with molecular docking. Steady state and time resolved fluorescence data revealed that PIA can quench the BSA fluorescence via a static mechanism: energy transfer from BSA to PIA occurs with high probability. The binding is strong (Kb ca. 105-106 L mol-1), spontaneous (ΔG° ca. -35.7 kJ mol-1 at 310 K) and entropy-driven (ΔS° = 0.146 kJ mol-1 K-1). There is just one main binding site (n ca. 1) for the BSA:PIA interaction and the α-helix content of the albumin does not suffer significant perturbation upon PIA binding. Molecular docking results suggest site I as the main binding site to PIA, which is able to interact with the Trp-212, Arg-217, Val-342 and Pro-446 residues.

OBJECTIVES: To establish cut-off values for growth hormone concentrations using clonidine as a secretagogue and an immunochemiluminescent assay as the method of measurement and to analyze the response time as well as the influence of gender, nutritional status and pubertal stage. METHODS: A total of 225 tests were performed in 3 patient groups, categorized as group 1 (normal), group 2 (idiopathic short stature) and group 3 (growth hormone deficiency). Among the 199 disease-free individuals, 138 were prepubertal, and 61 were pubertal. Clonidine (0.1 mg/m2) was orally administered, and the growth hormone level was measured by immunochemiluminescent assay. The growth hormone peak and the difference between the growth hormone peak and the baseline level were then analyzed. Statistical analyses were performed using Student’s t-test or the Mann-Whitney test and Kruskal-Wallis test followed by Dunn’s post hoc test. Cut-off values were determined using a receiver operating characteristic curve. RESULTS: Group 1 and group 2 had no difference in growth hormone peak, gender, body mass index standard deviation score, or pubertal stage. Group 3 exhibited a significantly lower growth hormone peak than the other groups did. The receiver operating characteristic curve demonstrated that growth hormone concentrations ≥ 3.0 ng/mL defined responsiveness to clonidine. In total, 3.02% of individuals in group 1 and group 2 were considered false positive, i.e., these children lacked growth hormone deficiency and had a peak below 3.0 ng/mL. CONCLUSION: Clonidine-stimulated growth hormone concentrations ≥3 ng/mL, as measured by immunochemiluminescent assay, suggest responsiveness to the stimulus regardless of gender, body mass index standard deviation score or pubertal stage.

Information on genetic diversity is essential to the characterization and utilization of germplasm. The genetic diversity of twenty-two sweet corn cultivars (seventeen open-pollinated varieties, OPV, and five hybrids, H) was investigated by applying simple sequence repeat markers. A total of 257 primers were tested, of which 160 were found to be usable in terms of high reproducibility for all the samples tested; 45 were polymorphic loci, of which 30 were used to assess the genetic diversity of sweet corn cultivars. We detected a total of 86 alleles using 30 microsatellite primers. The mean polymorphism was 82 %. The highest heterozygosity values (Ho = 0.20) were found in the PR030-Doce Flor da Serra and BR427 III OPVs, whereas the lowest values (0.14) were recorded in the MG161-Branco Doce and Doce Cubano OPVs. The polymorphism information content ranged from 0.19 (Umc2319) to 0.71 (Umc2205). The analysis of molecular variance revealed that most of the genetic variability was concentrated within the cultivars of sweet corn (75 %), with less variability between them (25 %). The consensus tree derived from the neighbor-joining (NJ) algorithm using 1,000 bootstrapping replicates revealed seven genetically different groups. Nei’s diversity values varied between 0.103 (Doce do Hawai × CNPH-1 cultivars) and 0.645 (Amarelo Doce × Lili cultivars), indicating a narrow genetic basis. The Lili hybrid was the most distant cultivar, as revealed by Principal Coordinates Analysis and the NJ tree. This study on genetic diversity will be useful for planning future studies on sweet corn genetic resources and can complement the breeding programs for this crop.

The stability of N-propylbutanimine (1) was investigated under different experimental conditions. The acid-catalyzed self-condensation that produced the E-enimine (4) and Z-inimine (5) was studied by experimental analyses and theoretical calculations. Since the calculations for the energy of 5 indicated that it had a lower energy than 4, yet 4 was the principal product, the self-condensation of 1 must be kinetically controlled.

O sonho do deslocamento entre Brasil-Europa pode ser encontrado de forma recorrente na bibliografia sobre a temática travesti. As modificações relativas ao tráfico de pessoas realizadas no Código Penal brasileiro, em 2005, possibilitam diversas interpretações para os termos facilitar e facilitação, criminalizando ações que, para este grupo, se constituíam, até então, como formas de sociabilidades. Argumento que o não reconhecimento da prostituição como um trabalho distancia essas travestis de outras brasileiras que trabalham indocumentadas, potencializando o envolvimento destas em situações de vulnerabilidade.

The dream of traveling between Brazil and Europe is easy to find in the referential bibliography about transvestites. The changes related to the trafficking in persons, in the Brazilian penal code in 2005, show how different interpretations of the terminology "facilitate" and "facilitation" made a strong impact on transvestites' lives, criminalizing some practices of this group that had in fact been part of their sociability. I argue that the unrecognized position of prostitution as legal work creates a substantial gap between the transvestites and the other illegal Brazilian workers, which leads them into potentially vulnerable situations.
