Abstract BACKGROUND: The burnout syndrome can be avoided and/or have its signs and symptoms reduced by knowing the five associated factors that help identify the health and working conditions of the professors of graduate programs. OBJECTIVE: To analyze the factors associated with burnout among faculty members of graduate stricto sensu programs. DESIGN AND SETTING: A cross-sectional study was conducted among 585 faculty members of Graduate Programs in Language Teaching and Linguistics in Brazil. METHODS: Data were collected through an online questionnaire. The outcomes were the dimensions of burnout and its related factors identified through multiple templates of logistic regression. RESULTS: Faculty members with increased chances of emotional exhaustion and depersonalization mentioned the use of medications due to labor activities. The negative influence of pace and intensity of work, thoughts about quitting the program, and having to produce three or more scientific articles were associated with higher chances of emotional exhaustion, while having to achieve nine hours per week in undergraduate programs was related to reduced personal accomplishment. Having a conjugal relationship, satisfaction with health and work, post-doctoral degree, autonomy, and good interpersonal relationships with faculty members of the program reduced the chances of emotional exhaustion. Reduced chances of depersonalization occurred among those who were satisfied with work, had good interpersonal relationships with advisees and faculty members, and received productivity funding. CONCLUSION: Sociodemographic, health, and occupational factors related to the dimensions of burnout were identified.

Abstract Introduction: The increase in the prevalence of aortic stenosis due to an aging population has led to an increasing number of surgical aortic valve replacements. Over the past 20 years, there has been a major shift in preference from mechanical to bioprosthetic valves. However, despite efforts, there is still no "ideal" bioprosthesis. It is crucial to understand the structure, biology, and function of native heart valves to design more intelligent, strong, durable, and physiological heart valve tissues. Methods: A comprehensive review of the literature was performed to identify articles reporting the basic mechanisms of bioprosthetic valve dysfunction and the biology of native valve cells. Searches were run in PubMed, MEDLINE® (the Medical Literature Analysis and Retrieval System Online), and Google Scholar. Terms for subject heading and keywords search included “biological heart valve dysfunction”, “bioprosthesis dysfunction”, “bioprosthesis degeneration”, and “tissue heart valves”. Results: All the relevant findings are summarized in the appropriate subsections. Structural dysfunction is a logical and expected consequence of the chemical, mechanical, and immunological processes that occur during fixation, manufacture, and implantation. Conclusion: Biological prosthesis valve dysfunction is a clinically significant process. It has become a major issue considering the growing rate of bioprosthesis implantation and improved long-term patient survival. Understanding bioprosthetic aortic valve degeneration from a basic science perspective is a key point to improve technologic advances and specifications that lead to a new generation of bioprostheses.

ABSTRACT Background: Transfusion of ABO-compatible non-identical platelets (PTLs), fresh plasma (FP) and red blood cells (RBCs) has been associated with increased morbidity and mortality of recipients. Trauma victims are frequently exposed to ABO non-identical products, given the need for emergency transfusions. Our goal was to evaluate the impact of the transfusion of ABO non-identical blood products on the severity and all-cause 30-day mortality of trauma patients. Methods: This was a retrospective single-center cohort, which included trauma patients who received emergency transfusions in the first 24 h of hospitalization. Patients were divided in two groups according to the use of <3 or ≥3 ABO non-identical blood products. The patient severity, measured by the Acute Physiology and Chronic Health Evaluation (APACHEII) score at ICU admission, and the 30-day mortality were compared between groups. Results: Two hundred and sixteen trauma patients were enrolled. Of these, 21.3% received ≥3 ABO non-identical blood products (RBCs, PLTs and FP or cryoprecipitate). The transfusion of ≥3 ABO non-identical blood products in the first 24 h of hospitalization was independently associated with a higher APACHEII score at ICU admission (OR = 3.28 and CI95% = 1.48–7.16). Transfusion of at least one unit of ABO non-identical PTLs was also associated with severity (OR = 10.89 and CI95% = 3.38–38.49). Transfusion of ABO non-identical blood products was not associated with a higher 30-day mortality in the studied cohort. Conclusion: The transfusion of ABO non-identical blood products and, especially, of ABO non-identical PLTs may be associated with the greater severity of trauma patients at ICU admission. The transfusion of ABO non-identical blood products in the trauma setting is not without risks.

RESUMO Objetivo: Avaliar estudantes de medicina do terceiro e sexto anos no Brasil em relação a seu conhecimento e atitudes sobre as políticas MPOWER da OMS para redução do uso do tabaco. Métodos: A Pesquisa Global de Estudantes de Profissões da Saúde da OMS foi aplicada em cinco coortes de estudantes de medicina avaliados no terceiro e sexto anos da graduação, entre 2008 e 2015. Foram feitas comparações entre os dois anos da graduação em relação às proporções de estudantes que experimentaram ou fizeram uso de produtos de tabaco nos últimos 30 dias antes da pesquisa; conhecimento e cumprimento das políticas antifumo no campus universitário; treinamento formal sobre estratégias de cessação do tabagismo; e autorreconhecimento como modelo de comportamento para pacientes/sociedade. Resultados: Dos 943 estudantes que preencheram a pesquisa, aproximadamente 6% haviam fumado cigarro nos últimos 30 dias antes da pesquisa. Ao compararmos o terceiro e sexto anos da graduação, observamos um aumento significativo na proporção de estudantes que tinham conhecimento sobre estratégias de cessação do tabagismo (22,74% vs. 95,84%; p < 0,001) e na daqueles que reconheciam seu papel como modelo para pacientes/sociedade (84,5% vs. 89,7%; p = 0,023). O conhecimento dos estudantes sobre as políticas de tabagismo existentes no campus universitário associou-se ao aumento no autorreconhecimento como modelo de comportamento (diferença absoluta ajustada = 6,7%; p ajustado = 0,050). Conclusões: O conhecimento sobre estratégias de cessação do tabagismo e a autorreconhecimento como modelo de comportamento para pacientes/sociedade aumentaram ao longo da graduação e estão associados à implementação de políticas antifumo.

ABSTRACT Objective: To evaluate third- and sixth-year medical students in Brazil in terms of their knowledge of and attitudes toward the WHO MPOWER policies to reduce tobacco use. Methods: The WHO Global Health Professions Student Survey was applied in five cohorts of medical students evaluated in their third and sixth years of medical school, between 2008 and 2015. Comparisons were drawn between the two years of medical school in terms of the proportions of students who experimented with or used tobacco products in the last 30 days prior to the survey; knowledge of and compliance with smoke-free policies on the university campus; formal training on smoking cessation strategies; and self-recognition as role models for patients/society. Results: Of the 943 students who completed the survey, approximately 6% had smoked cigarettes in the last 30 days prior to the survey. Comparing the third and sixth years of medical school, we observed a significant increase in the proportion of students who were knowledgeable about smoking cessation strategies (22.74% vs. 95.84%; p < 0.001) and in that of those who recognized their role as models for patients/society (84.5% vs. 89.7%; p = 0.023). Student knowledge of the smoking policies on the university campus was associated with an increase in self-recognition as role models (adjusted absolute difference = 6.7%; adjusted p = 0.050). Conclusions: Knowledge of smoking cessation strategies and self-recognition as role models for patients/society increase over the course of medical school and are associated with the implementation of smoke-free policies.

RESUMO A deficiência de alfa-1 antitripsina (DAAT) é um distúrbio genético raro causado por uma mutação no gene SERPINA1, que codifica o inibidor de protease alfa-1 antitripsina (AAT). A DAAT predispõe os indivíduos a DPOC e doença hepática. O diagnóstico precoce é essencial para a implementação de medidas preventivas e para limitar a carga da doença. Embora diretrizes nacionais e internacionais para o diagnóstico e manejo da DAAT estejam disponíveis há 20 anos, mais de 85% dos casos não são diagnosticados e, portanto, não são tratados. No Brasil, os motivos para o subdiagnóstico da DAAT incluem o desconhecimento dos médicos sobre a condição, a diversidade racial da população, o fato de os níveis séricos de AAT serem avaliados em um número limitado de indivíduos e a falta de ferramentas diagnósticas convenientes. O diagnóstico da DAAT baseia-se em resultados de exames laboratoriais. A abordagem diagnóstica padrão envolve a avaliação dos níveis séricos de AAT, seguida de fenotipagem, genotipagem, sequenciamento gênico ou suas combinações para detecção da mutação específica. Nos últimos 10 anos, novas técnicas foram desenvolvidas, oferecendo uma alternativa rápida, minimamente invasiva e confiável aos métodos tradicionais de teste. Um desses testes disponíveis no Brasil é o teste de genotipagem A1AT, que analisa simultaneamente as 14 mutações mais prevalentes da DAAT usando DNA extraído de swab bucal ou de sangue em papel-filtro. Esses avanços podem contribuir para a superação do problema do subdiagnóstico no Brasil e em outros países, bem como podem aumentar a taxa de detecção da DAAT e, portanto, mitigar os malefícios do diagnóstico tardio.

ABSTRACT Alpha-1 antitrypsin deficiency (AATD) is a rare genetic disorder caused by a mutation in the SERPINA1 gene, which encodes the protease inhibitor alpha-1 antitrypsin (AAT). Severe AATD predisposes individuals to COPD and liver disease. Early diagnosis is essential for implementing preventive measures and limiting the disease burden. Although national and international guidelines for the diagnosis and management of AATD have been available for 20 years, more than 85% of cases go undiagnosed and therefore untreated. In Brazil, reasons for the underdiagnosis of AATD include a lack of awareness of the condition among physicians, a racially diverse population, serum AAT levels being assessed in a limited number of individuals, and lack of convenient diagnostic tools. The diagnosis of AATD is based on laboratory test results. The standard diagnostic approach involves the assessment of serum AAT levels, followed by phenotyping, genotyping, gene sequencing, or combinations of those, to detect the specific mutation. Over the past 10 years, new techniques have been developed, offering a rapid, minimally invasive, reliable alternative to traditional testing methods. One such test available in Brazil is the A1AT Genotyping Test, which simultaneously analyzes the 14 most prevalent AATD mutations, using DNA extracted from a buccal swab or dried blood spot. Such advances may contribute to overcoming the problem of underdiagnosis in Brazil and elsewhere, as well as being likely to increase the rate detection of AATD and therefore mitigate the harmful effects of delayed diagnosis.

Resumen El artículo en cuestión pretende estudiar el colectivo poético Vila Cultural Cemitério de Automóveis, donde tienen lugar el festiva literario Londrix y el evento Poesia in Concert. A partir de la comprensión del experimentalismo poético, como el empleo de materiales y medios físicos que modifican el lenguaje poético, se demuestra cómo colectivos poéticos protagonizan, mediante prácticas performáticas, transformaciones en la literatura brasilera. El análisis se centra en mecanismos de producción poética en la contemporaneidad, comprendiendo cómo se desarrolla la "red afectiva" entre los poetas y cómo se articula la asociación con la industria musical, por medio de grabaciones de CDs y de la realización de espectáculos, que acaban por colocar en paralelo sistemas culturales de producción musical y literario. La performance es el aspecto más significativo de los colectivos, ya que los cuerpos interaccionan con el texto literario, subvirtiendo su sentido y establece conexiones con el público y la ciudad.

Abstract This article aims to study the poetic collective Vila Cultural Cemitério de Automóveis, where the Londrix literary festival and Poesia in Concert events are held. From the understanding of poetic experimentalism as the use of materials and physical means that modify the poetic language, we intend to show how poetic groups lead the transformation of Brazilian literature through performing poetic texts. The analysis is focused on the contemporary mechanisms of poetic production, in a way to understand how the "affective network" between poets is developing as well as how poetry is associated with music industry, through CD recordings and concerts, parallel placing cultural systems of literature and music. Performance is the most significant aspect of collectives, as bodies interact with the literary text, subverting its meaning and establishing connections with the public and the city.

RESUMO Objetivo: Caracterizar uma população de portadores de bronquiectasias e correlacionar aspectos clínicos, radiológicos e funcionais com a gravidade da dispneia. Métodos: Estudo transversal realizado em adultos, portadores de bronquiectasias confirmadas por TCAR, categorizados de acordo com a gravidade da dispneia (pacientes pouco e muito sintomáticos), correlacionando-os com seus parâmetros clínicos, funcionais (espirometria, volumes pulmonares e DLCO) e tomográficos. Resultados: Foram avaliados 114 pacientes (47 homens, 41%). A mediana (intervalo interquartil) de idade foi de 42 (30-55) anos. A etiologia mais frequente foi idiopática. Em relação à colonização, 20 pacientes (17,5%) eram colonizados por Pseudomonas aeruginosa e grande parte fazia uso de macrolídeo continuamente (51,8%). Quanto à gravidade da dispneia, ela foi considerada moderada em 54 pacientes (47,4%) pelo escore Exacerbation in previous year, FEV1, Age, Colonization, Extension, and Dyspnea e leve em 50 (43,9%) pelo Bronchiectasis Severity Index. O padrão funcional mais encontrado foi distúrbio ventilatório obstrutivo (em 83%), e 68% apresentavam aprisionamento aéreo. Pacientes com maior grau de dispneia apresentaram maior prevalência de distúrbio obstrutivo na espirometria, e a maioria dos parâmetros funcionais apresentaram acurácia razoável em discriminar a gravidade da dispneia. Conclusões: Pacientes com bronquiectasias e maior gravidade da dispneia apresentaram um comprometimento funcional mais expressivo. A medida de volumes pulmonares complementou os dados da espirometria. Por se tratar de uma condição complexa e heterogênea, uma única variável parece não ser suficiente para caracterizar a condição clínica de forma global.

ABSTRACT Objective: To characterize a population of patients with bronchiectasis, correlating clinical, radiological, and functional aspects with the severity of dyspnea. Methods: This was a cross-sectional study involving adult patients with HRCT-confirmed bronchiectasis, categorized according to the severity of dyspnea (as being mildly or severely symptomatic, on the basis of the modified Medical Research Council scale). We correlated the severity of dyspnea with clinical parameters, functional parameters (spirometry values, lung volumes, and DLCO), and CT parameters. Results: We evaluated 114 patients, 47 (41%) of whom were men. The median age (interquartile range) was 42 years (30-55 years). The most common form was idiopathic bronchiectasis. Of the 114 patients, 20 (17.5%) were colonized with Pseudomonas aeruginosa and 59 (51.8%) were under continuous treatment with macrolides. When we applied the Exacerbation in the previous year, FEV1, Age, Colonization, Extension, and Dyspnea score, the severity of dyspnea was categorized as moderate in 54 patients (47.4%), whereas it was categorized as mild in 50 (43.9%) when we applied the Bronchiectasis Severity Index. The most common lung function pattern was one of obstruction, seen in 95 patients (83.3%), and air trapping was seen in 77 patients (68.7%). The prevalence of an obstructive pattern on spirometry was higher among the patients with dyspnea that was more severe, and most functional parameters showed reasonable accuracy in discriminating between levels of dyspnea severity. Conclusions: Patients with bronchiectasis and dyspnea that was more severe had greater functional impairment. The measurement of lung volumes complemented the spirometry data. Because bronchiectasis is a complex, heterogeneous condition, a single variable does not seem to be sufficient to provide an overall characterization of the clinical condition.

Resumo: O estudo se orienta ao uso pedagógico da expressão literária que aponte os elementos de literariedade em narrativas históricas. Para isso, verificamos a literariedade presente nos relatórios do prefeito Graciliano Ramos, produzidos entre 1929 e 1930. O resgate histórico da rotina administrativa revela a educação literária do autor, repleta de realidade poética e objetividade, ainda que burocrática. Preliminarmente, apresentamos os fundamentos da função pública municipal, sob a égide da Constituição de 1891, para reconhecer a resistência literária e estilística do autor. Consideramos os traços de verossimilhança, alegoria, metáforas, ironia, caricatos nos relatórios, suficientes para apontar as virtudes pedagógicas de um texto literário.

Abstract: This study is in the realm of the pedagogical use of literary expression that identifies literary aspects in historical narratives. We deal with the concept of literariness in the reports of Mayor Graciliano Ramos between 1929 and 1930. The historical rescue of the administrative routine reveals how the literary education of the author emerges in a poetic reality and objectivity despite of its bureaucratic nature. This article discusses the basic principals of the municipal public function under the aegis of the Constitution of 1891, in a way to identify the literary and stylistic resistance of the author. We then consider some aspects such as: verisimilitude, allegory, metaphors, and irony presented in the reports, which demonstrate the pedagogical virtues of a literary text.

RESUMO Objetivo: Uma resolução do governo do estado de São Paulo estabeleceu um protocolo para a solicitação de medicamentos gratuitos para DPOC, incluindo o brometo de tiotrópio, com a criação de centros autorizadores regionais para avaliar essas solicitações e liberar sua dispensação, dado seu custo elevado. Nosso objetivo foi analisar essas solicitações recebidas em um centro autorizador que atende cidades da Grande São Paulo entre 2011 e 2016. Métodos: Dados referentes a liberações, devoluções ou indeferimentos das solicitações foram compilados e analisados quanto aos motivos para tal. Posteriormente, foram incluídos dados clínicos e funcionais dos pacientes. Resultados: Foram analisadas 7.762 solicitações para a dispensação do medicamento. Houve predomínio de pacientes do sexo masculino. A média de idade foi de 66 anos, sendo 12% dos pacientes ainda tabagistas, 88% de exacerbadores frequentes e 84% com dispneia grave/muito grave. A média de VEF1 foi de 37,2% do previsto. Em 2013, houve diminuição de 24,5% das solicitações totais em relação a 2012, e o menor número foi em 2015. A maioria das solicitações foi autorizada (65%). Os principais motivos para o indeferimento/devolução das solicitações foram relação VEF1/CVF > 0,7 após broncodilatador, VEF1 > 50% do previsto após broncodilatador e falta de indicação de uso prévio de broncodilatador adrenérgico de longa duração. O total de solicitações devolvidas/indeferidas sofreu discreta redução no período, assim como houve melhora na qualidade do preenchimento dos formulários. Conclusões: Os resultados permitiram identificar o perfil das solicitações, assim como as características dos pacientes com DPOC por região atendida no centro autorizador, contribuindo para a otimização de medidas de saúde pública locais.

ABSTRACT Objective: A resolution passed by the government of the Brazilian state of São Paulo established a protocol for requesting free COPD medications, including tiotropium bromide, creating regional authorization centers to evaluate and approve such requests, given the high cost of those medications. Our objective was to analyze the requests received by an authorization center that serves cities in the greater metropolitan area of (the city of) São Paulo between 2011 and 2016. Methods: Data regarding the authorization, return, or rejection of the requests were compiled and analyzed in order to explain those outcomes. Subsequently, the clinical and functional data related to the patients were evaluated. Results: A total of 7,762 requests for dispensing COPD medication were analyzed. Requests related to male patients predominated. Among the corresponding patients, the mean age was 66 years, 12% were smokers, 88% had frequent exacerbations, and 84% had severe/very severe dyspnea. The mean FEV1 was 37.2% of the predicted value. The total number of requests decreased by 24.5% from 2012 to 2013 and was lowest in 2015. Most (65%) of the requests were accepted. The main reasons for the rejection/return of a request were a post-bronchodilator FEV1/FVC ratio > 0.7, a post-bronchodilator FEV1 > 50% of the predicted value, and failure to provide information regarding previous use of a long-acting β2 agonist. During the study period, the total number of requests returned/rejected decreased slightly, and there was improvement in the quality of the data included on the forms. Conclusions: Here, we have identified the characteristics of the requests for COPD medications and of the corresponding patients per region served by the authorization center analyzed, thus contributing to the improvement of local public health care measures.

RESUMO Objetivo: Caracterização clínica, funcional, radiológica e genotípica dos pacientes portadores de mutações do gene da alfa-1 antitripsina (A1AT) em um centro de referência em doença pulmonar obstrutiva crônica (DPOC) no Brasil. Métodos: Estudo transversal de pacientes com mutação no gene da A1AT compatível com deficiência. Foram avaliadas características genotípicas, demográficas, clínicas, tomográficas, de função pulmonar, e dosagem de A1AT. Resultados: De 43 pacientes suspeitos para deficiência de alfa-1 antitripsina (DA1AT), a doença foi confirmada por genotipagem em 27. A mediana da dosagem de A1AT foi de 45 mg/dL, e 4 pacientes (15%) apresentavam dosagens normais. A idade mediana foi de 54 anos, 63% dos participantes eram do sexo masculino e a idade do início dos sintomas prevalente foi aos 40 anos. A mediana do volume expiratório forçado no primeiro segundo (VEF1) foi de 1,37 L (43% do previsto). Enfisema tomográfico foi encontrado em 77,8% dos indivíduos, sendo panlobular em 76% e de predomínio em lobos inferiores em 48%. A frequência de bronquiectasias foi de 52%, e a de espessamento brônquico, de 81,5%. O genótipo mais encontrado foi Pi*ZZ (40,7%). Os demais genótipos foram: Pi*SZ (18,5%), Pi*M1Z (14,8%), Pi*M1S (7,4%), Pi*M2Z (3,7%), Pi*M1I (3,7%), Pi*ZMnichinan (3,7%), Pi*M3Plowell (3,7%) e Pi*SF (3,7%). Não encontramos diferença significativa para idade, carga tabágica, VEF1 e presença de bronquiectasias entre os grupos com dosagem de A1AT normal versus alterada, nem entre 1 alelo versus 2 alelos com mutação para DA1AT. Conclusões: Nossos pacientes apresentaram alta frequência de enfisema, bronquiectasias e espessamento brônquico, com início precoce dos sintomas respiratórios. O genótipo mais frequente foi Pi*ZZ, embora genótipos heterozigotos e níveis normais de A1AT também tenham se manifestado com doença pulmonar significativa.

ABSTRACT Objective: The clinical, functional, radiological and genotypic descriptions of patients with an alpha-1 antitrypsin (A1AT) gene mutation in a referral center for COPD in Brazil. Methods: A cross-sectional study of patients with an A1AT gene mutation compatible with deficiency. We evaluated the A1AT dosage and genotypic, demographic, clinical, tomographic, and functional characteristics of these patients. Results: Among the 43 patients suspected of A1AT deficiency (A1ATD), the disease was confirmed by genotyping in 27 of them. The A1AT median dosage was 45 mg/dL, and 4 patients (15%) had a normal dosage. Median age was 54, 63% of the patients were male, and the respiratory symptoms started at the age of 40. The median FEV1 was 1.37L (43% predicted). Tomographic emphysema was found in 77.8% of the individuals. The emphysema was panlobular in 76% of them and 48% had lower lobe predominance. The frequency of bronchiectasis was 52% and the frequency of bronchial thickening was 81.5%. The most common genotype was Pi*ZZ in 40.7% of participants. The other genotypes found were: Pi*SZ (18.5%), PiM1Z (14.8%), Pi*M1S (7.4%), Pi*M2Z (3.7%), Pi*M1I (3.7%), Pi*ZMnichinan (3.7%), Pi*M3Plowell (3.7%), and Pi*SF (3.7%). We did not find any significant difference in age, smoking load, FEV1, or the presence of bronchiectasis between the groups with a normal and a reduced A1AT dosage, neither for 1 nor 2-allele mutation for A1ATD. Conclusions: Our patients presented a high frequency of emphysema, bronchiectasis and bronchial thickening, and early-beginning respiratory symptoms. The most frequent genotype was Pi*ZZ. Heterozygous genotypes and normal levels of A1AT also manifested significant lung disease.
