Resumo: Introdução: Medicina de emergência é uma especialidade relativamente nova no Brasil, aprovada apenas em 2016, e programas de treinamento em residência têm sido instituídos desde então. O ambiente da emergência é conhecido por representar uma tensão entre vida e morte nos profissionais, o que culmina em altos índices de adoecimento mental nessa população. A pandemia da Covid-19 aparenta estar influenciando nas taxas de depressão, ansiedade e burnout de profissionais de saúde. Objetivo: Este estudo teve como objetivos avaliar os sintomas de burnout, depressão e ansiedade em residentes de medicina de emergência brasileiros durante a pandemia da Covid-19 e comparar as crenças deles sobre a prática clínica relacionada aos pacientes com a doença. Método: Um estudo quantitativo foi realizado com uma amostra conveniente de médicos residentes voluntários, por meio de uma pesquisa on-line anônima disponível durante o mês de abril de 2020. Esta investigação coletou informações sociodemográficas e utilizou as seguintes escalas: Oldenburg Burnout Inventory (OLBI) para mensurar burnout, Patient Health Questionnaire (PHQ-9) para mensurar depressão e General Anxiety Disorders (GAD-7) para mensurar transtorno de ansiedade generalizada. Neste estudo, também foi desenvolvido um Questionário sobre o Impacto da Covid-19 (CIQ-19) para acessar as crenças e práticas clínicas relacionadas aos pacientes com Covid-19. Resultado: A pesquisa foi composta de 63 voluntários, aproximadamente 26,35% dos residentes em medicina de emergência no Brasil. Apenas 39,6% dos residentes se sentiram seguros enquanto trabalhavam com pacientes com Covid-19. Encontraram-se sintomas leves de depressão em 68,2%, seguidos de sintomas de ansiedade em 50,7% e burnout em 54,0%. Aproximadamente 12% dos residentes não fazem nada relação à própria saúde mental, alguns preferem conversar com familiares e amigos (36,1%), e outros discutem com a equipe de suporte (24,3%) quando precisam de atendimento. Conclusão: Os residentes de medicina de emergência possuem altos índices de adoecimento mental, e isso pode piorar quando submetidos a situações estressantes e desconhecidas, como a pandemia da Covid-19. Iniciativas devem ser tomadas para melhorar a saúde mental desses médicos. Propõe-se que as instituições de saúde ofereçam aos supervisores médicos uma visão mais próxima e exclusiva sobre os médicos em treinamento. A proposta de um programa de mentoria é uma oportunidade de refletir sobre melhorias técnicas e pessoais para médicos residentes.

Abstract: Introduction: Emergency medicine is a relatively new medical specialty in Brazil, approved just in 2016. Residency training programs have been implemented ever since. The emergency environment is known to represent a death-and-life tension on the professional team, culminating with high rates of mental illness in this population. The Covid-19 pandemic seems to be affecting these rates of depression, anxiety, and burnout in health professionals. Objective: To assess the symptoms of burnout, depression, and anxiety in Brazilian medical residents of Emergency Medicine during the Covid-19 pandemic and compare the residents’ beliefs regarding clinical practice related to Covid-19 patients. Methods: A quantitative study was conducted with a convenience sample of volunteer medical residents from an anonymous online survey, available during April 2020. This investigation collected sociodemographic information and used the Oldenburg Burnout Inventory (OLBI) to measure burnout; the Patient Health Questionnaire (PHQ-9) to measure depression; and the General Anxiety Disorders (GAD-7) to measure generalized anxiety disorder. This study also developed a Covid-19 Impact Questionnaire (CIQ-19) to assess the residents’ beliefs and clinical practices related to Covid-19 patients. Results: The survey consisted of 63 respondents, about 26,35% of emergency medicine residents in Brazil. Only 39.6% residents felt safe while working with Covid-19 patients. Mild depressive symptoms were found in 68.2% of the residents, followed by anxiety symptoms in 50.7% and burnout in 54.0% overall. About 12% of the residents do nothing about their mental health status, while some prefer to talk with family or friends (36.1%) and discuss with their team support (24.3%) when they need mental health care. Conclusion: Emergency medicine residents have high rates of mental illness and it could get worse when submitted to stressful and unknown situations, such as the Covid-19 pandemic. Initiatives should be made to improve these physicians’ mental health status. It is proposed that health institutions pay medical supervisors a closer and more unique look at physicians in training. A mentoring program proposal is an opportunity to reflect on technical and personal improvements for medical residents.

ABSTRACT BACKGROUND: 2020 was a challenging year for all healthcare professionals worldwide. In São Paulo, Brazil, the virus SARS-CoV-2 took 47,222 lives up to December 29, 2020. The front line of medical professionals in São Paulo was composed of many residents, who were transferred from their rotations to cover the needs of the pandemic. OBJECTIVE: To identify medical residents’ mental health and clinical issues, regarding symptoms of burnout, depression and anxiety during the pandemic, and to compare them among specialties. DESIGN AND SETTING: Quantitative study using a convenience sample of medical resident volunteers who responded to an anonymous online survey that was available during April 2020. METHODS: This investigation collected sociodemographic information and used the Oldenburg Burnout Inventory (OLBI) to measure burnout, the Patient Health Questionnaire (PHQ-9) to measure depression and the General Anxiety Disorder (GAD-7) scale to measure anxiety symptoms. This study also developed a COVID-19 Impact Questionnaire (CIQ-19) to assess the residents’ beliefs and clinical practices relating to COVID-19 patients. RESULTS: The sample comprised 1,392 medical residents in São Paulo, Brazil. Clinical specialty physicians showed the highest rates of anxiety symptoms (52.6%) and burnout (51.2%), among the specialties. CONCLUSION: Clinical specialty residents are at higher risk of anxiety, depression and burnout. The symptoms of anxiety and depression have worsened during the COVID-19 pandemic. There is a general need for mental health support interventions for medical resident physicians, which requires reinforcement during this worldwide crisis.

OBJECTIVES: This study aims to assess the symptoms of burnout, depression, and anxiety in Brazilian medical residents during the COVID-19 pandemic and to compare residents’ beliefs and clinical practices related to COVID-19 patients among all six years of medical residency training in Brazil. METHODS: A quantitative study was conducted in April 2020 with a convenience sample of medical resident volunteers from an anonymous online survey. This investigation collected sociodemographic information and used the Oldenburg Burnout Inventory (OLBI) to measure burnout, the Patient Health Questionnaire (PHQ-9) to measure depression, and the General Anxiety Disorders (GAD-7) to measure generalized anxiety disorder. This study also developed a COVID-19 Impact Questionnaire (CIQ-19) to assess the residents’ beliefs and clinical practices related to COVID-19 patients. RESULTS: Our sample comprised 3071 respondents. Depressive symptoms were the most common among second-year residents (70.5%), followed by anxiety symptoms (56.0%) and burnout (55.2%) among fourth-year residents. We also observed burnout symptoms (55.1%) among second-year residents. CONCLUSION: The COVID-19 pandemic increased the risk of mental illnesses in some years of residency. Our study could not conclude the reasons why the incidence varies among levels of physician training. Final year medical residents have avoided seeing COVID-19 patients.

Resumo: Introdução: A pandemia de Covid-19 impôs à educação médica novas modalidades de ensino a distância. Com isso, os programas de mentoria, prática do processo de formação em Medicina, precisaram se adequar à nova situação com a implementação da mentoria virtual destinada aos alunos. Relato de experiência: O grupo de mentoria reforçou a importância desse processo para a formação profissional, principalmente diante dos anseios e das inseguranças causados pela pandemia. A mudança para os encontros virtuais foi bem recebida pelos mentores e mentorandos. Por fim, o processo de mentoria virtual permitiu a discussão de temas mais leves, conversas com menos timidez sobre assuntos difíceis e reforçando a identidade do grupo. Discussão: Os programas de mentoria precisam investir em melhores treinamentos para os mentores, como forma de promover a qualidade do processo grupal, sem contar com os benefícios que isso traria ao mentor que passou a atuar de modo remoto com seus mentorandos. A pandemia acirrou as divergências entre gerações e os domínios das ferramentas virtuais por parte dos grupos de mentores e mentorandos. Os mentores e docentes do processo de formação médica precisam atentar para o sofrimento mental e as fragilidades dos alunos, na tentativa de minimizar esses problemas por meio da mentoria, das narrativas e do compartilhamento de experiências que permitem a suspensão do automatismo cotidiano. Conclusão: Não se observou nenhum tipo de prejuízo acerca da mentoria virtual, e não existe empecilho para que ela continue na modalidade remota, após a pandemia de Covid-19.

Abstract: Introduction: The Covid-19 pandemic imposed new forms of distance learning on medical education. Thus, mentoring programs, a practice in the medical education process, needed to adapt to the new situation with the implementation of virtual mentoring for students. Experience report: The mentoring group reinforced the importance of this process for professional training, especially in view of the anxieties and insecurities caused by the pandemic. The move to virtual meetings was well received by mentors and mentees. Finally, the virtual mentoring process allowed lighter topics to be discussed, more open conversations about difficult issues and reinforced the identity of that group. Discussion: Mentoring programs need to invest in better training for mentors, as a way to promote the quality of the group process, not to mention the benefits that this would bring to the mentor who started to work remotely with their mentors. The pandemic increased the discrepancies between generations and the mastering of virtual tools by mentors and mentees. Mentors and teachers in the medical education process need to pay attention to the mental suffering and weaknesses of students, in an attempt to minimize these problems through mentoring according to the narratives and the sharing of experiences that help break the automatized daily routine. Conclusion: No damage was observed about virtual mentoring, and there would be no obstacle for it to remain in remote mode after the Covid-19 pandemic.

Resumo O objetivo deste estudo é compreender as tensões presentes no medo de errar por conta dos riscos e danos que tal erro causaria aos envolvidos. Este é um estudo qualitativo baseado nas narrativas das experiências de 10 médicos atuantes no estado de São Paulo, Brasil. O conceito e a caracterização do erro foram discutidos, bem como o medo de cometê-lo, a proximidade com o erro, como lidar com ele e como evitá-lo. A análise aponta pressões excessivas no tocante a práticas sem erros na profissão médica, considerando a existência de uma relação médico-paciente bem estabelecida de forma a facilitar a gestão de erros médicos. Erros médicos ocorrem, mas a falta de informação e discussão sobre o tema costuma levar ao seu encobrimento, uma vez que médicos temem o possível julgamento feito pela sociedade e por seus pares. O estabelecimento de programas que encorajem a conduta médica apropriada caso um erro ocorra requer respostas coerentes para a humanização da ciência médica no Brasil.

Abstract The objective of this study is to better understand the tensions involved in the fear of making an error due to the harm and risk this would pose to those involved. This is a qualitative study based on the narratives of the experiences lived by ten acting physicians in the state of São Paulo, Brazil. The concept and characterization of errors were discussed, as well as the fear of making an error, the near misses or error in itself, how to deal with errors and what to do to avoid them. The analysis indicates an excessive pressure in the medical profession for error-free practices, with a well-established physician-patient relationship to facilitate the management of medical errors. The error occurs but the lack of information and discussion often leads to its concealment due to fear of possible judgment by society or peers. The establishment of programs that encourage appropriate medical conduct in the event of an error requires coherent answers for humanization in Brazilian medical science.

Canine visceral leishmaniasis (CVL) diagnosis is still a challenge in endemic areas with limited diagnostic resources. This study proposes a score with the potential to distinguish positive CVL cases from negative ones. We studied 265 dogs that tested positive for CVL on ELISA and parasitological tests. A score ranging between 0 and 19 was recorded on the basis of clinical signs. Dogs with CVL had an overall higher positivity of the majority of clinical signs than did dogs without CVL or with ehrlichiosis. Clinical signs such as enlarged lymph nodes (83.93%), muzzle/ear lesions (55.36%), nutritional status (51.79%), bristle condition (57.14%), pale mucosal colour (48.21%), onychogryphosis (58.93%), skin lesion (39.28%), bleeding (12.50%), muzzle depigmentation (41.07%), alopecia (39.29%), blepharitis (21.43%), and keratoconjunctivitis (42.86%) were more frequent in dogs with CVL than in dogs with ehrlichiosis or without CVL. Moreover, the clinical score increased according to the positivity of all diagnostic tests (ELISA, p < 0.001; parasite culture, p = 0.0021; and smear, p = 0.0003). Onychogryphosis (long nails) [odds ratio (OR): 3.529; 95% confidence interval (CI): 1.832-6.796; p < 0.001], muzzle depigmentation (OR: 4.651; 95% CI: 2.218-9.750; p < 0.001), and keratoconjunctivitis (OR: 5.400; 95% CI: 2.549-11.441; p < 0.001) were highly associated with CVL. Interestingly, a score cut-off value ≥ 6 had an area under the curve of 0.717 (p < 0.0001), sensitivity of 60.71%, and specificity of 73.64% for CVL diagnosis. The clinical sign-based score for CVL diagnosis suggested herein can help veterinarians reliably identify dogs with CVL in endemic areas with limited diagnostic resources.

Resumo O erro médico refere-se a circunstância que atinge a pessoa em decorrência de atuação médica baseada em atitude imprudente, negligente ou imperita. No Brasil tem crescido o número de casos, mas a discussão a respeito da vítima é quase inexistente. Este trabalho buscou delinear a perspectiva da vítima de erro médico. Utilizando uma entrevista semiestruturada, foi possível conhecer as experiências das vítimas e perceber de que maneira enfrentaram os desafios impostos. Observou-se a perplexidade ao descobrir-se vítima, e a dificuldade em aceitar-se como tal. As mudanças impostas pelo erro acarretaram transformações comportamentais e de atitudes, como a falta de confiança nos profissionais médicos. Sofrimento e sentimentos negativos passam a fazer parte da vivência dessas pessoas. Dessa maneira, é necessário criar estratégias que permitam auxílio e cuidado da saúde mental das pessoas envolvidas com o erro médico.

Abstract Medical malpractice refers to the circumstance of harming a person as the result of medical performance based on a reckless, negligent or inexpert approach. In Brazil, while the number of such cases is increasing, discussion of the subject is almost absent. The present study sought to elucidate some of the challenges found in the situations of the victims of medical malpractice. The experience of the victims was accessed through a semi-structured interview. The confusion of individuals when they discovered they had become victims was noted, as well as a difficulty in accepting the status of victim. The effects of the malpractice led to transformations both in behavior and in attitudes, such as a lack of confidence in medical professionals. It is therefore necessary to create strategies to help and care for the mental health of victims of medical malpractice.

Resumen El error médico se refiere a una circunstancia que afecta a una persona como resultado de una operación médica basada en actitudes imprudentes, negligentes o de impericia. En Brasil se ha incrementado el número de casos, pero la discusión en relación a la víctima es casi inexistente. Este estudio tuvo como objetivo dilucidar algunos de los desafíos presentes en la situación de las víctimas de errores médicos. A partir del empleo de una entrevista semi-estructurada, fue posible el acceso a las experiencias de las víctimas y se logró una aproximación a los modos en que enfrentaron los desafíos impuestos. Se observó la perplejidad de estas personas al percibirse como víctimas y la dificultad en aceptarse en tanto tales. Las transformaciones impuestas por el error dieron lugar a cambios en los comportamientos y las actitudes, por ejemplo, la falta de confianza en los profesionales de la medicina. El sufrimiento y los sentimientos negativos comenzaron a formar parte de las vivencias de estas personas. Por lo tanto, es necesario crear estrategias de acompañamiento y cuidado de la salud mental de las personas afectadas por errores médicos.

RESUMO Esse texto mostra a importância de apontar as dificuldades de uma pesquisa com tema tão delicado e ao mesmo tempo relevante para a atualidade. Descrevem-se alguns entraves que o pesquisador pode encontrar ao desenvolver sua pesquisa, reforçando a carência desse tipo de publicação no meio científico e almejando uma impulsão nas discussões sobre dificuldades metodológicas na educação médica.

ABSTRACT This paper demonstrates the importance of pointing out the difficulties of a research study focused on a subject matter which is both highly sensitive and relevant to the modern world. Some obstacles that may confront the researcher during the development of the study are described, underlining the lack of this kind of publication in the scientific community and aiming to drive discussions regarding methodological difficulties in medical education.

Asymptomatic Plasmodium infection carriers represent a major threat to malaria control worldwide as they are silent natural reservoirs and do not seek medical care. There are no standard criteria for asymptomaticPlasmodium infection; therefore, its diagnosis relies on the presence of the parasite during a specific period of symptomless infection. The antiparasitic immune response can result in reducedPlasmodium sp. load with control of disease manifestations, which leads to asymptomatic infection. Both the innate and adaptive immune responses seem to play major roles in asymptomatic Plasmodiuminfection; T regulatory cell activity (through the production of interleukin-10 and transforming growth factor-β) and B-cells (with a broad antibody response) both play prominent roles. Furthermore, molecules involved in the haem detoxification pathway (such as haptoglobin and haeme oxygenase-1) and iron metabolism (ferritin and activated c-Jun N-terminal kinase) have emerged in recent years as potential biomarkers and thus are helping to unravel the immune response underlying asymptomatic Plasmodium infection. The acquisition of large data sets and the use of robust statistical tools, including network analysis, associated with well-designed malaria studies will likely help elucidate the immune mechanisms responsible for asymptomatic infection.

A compreensão dos princípios científicos e a interpretação de artigos é necessária em qualquer especialidade médica. Entretanto, inexistem publicações sobre o conhecimento teórico e prático dos otorrinolaringologistas brasileiros. OBJETIVO: Avaliar a formação e o conhecimento científico de médicos da área de Otorrinolaringologia. MÉTODO: Durante dois congressos nacionais da especialidade, os participantes foram convidados a preencher questionário sobre prática e conhecimento científico para residentes e especialistas dessa área. RESULTADOS E CONCLUSÃO: Participaram do estudo 73 médicos (52% otorrinolaringologistas e 38% residentes), com idade entre 18 e 65 anos. Cerca de dois terços envolveram-se em alguma atividade científica durante a graduação e/ou referiram já ter escrito um artigo científico. Os médicos que já participaram de projetos de pesquisa sentem-se mais preparados para interpretar um artigo científico e conduzir um projeto de pesquisa (p = 0,0103 e p = 0,0240, respectivamente). Aqueles que participaram de projetos de pesquisa ou já escreveram um artigo tiveram melhor desempenho nos conceitos científicos teóricos (p = 0,0101 e p = 0,0103, respectivamente). Entretanto, o índice geral de acertos nas questões referentes ao conhecimento científico foi de 46,1%. Dessa forma, identificamos que há deficiências na formação científica dos otorrinolaringologistas brasileiros que podem ser atenuadas pela participação em projetos de pesquisa.

Physicians from all medical specialties are required to understand the principles of science and to interpret medical literature. Yet, the levels of theoretical and practical knowledge held by Brazilian otorhinolaryngologists has not been evaluated to date. OBJECTIVE: To assess the background and level of scientific knowledge of Brazilian otorhinolaryngologists. METHOD: Participants of two national ENT meetings were invited to answer a questionnaire to assess scientific practice and knowledge. RESULTS AND CONCLUSION: This study included 73 medical doctors (52% otorhinolaryngologists and 38% residents) aged between 18 and 65 years. About two-thirds have been involved in some form of scientific activity during undergraduate education and/or reported to have written at least one scientific paper. Physicians who took part in research projects felt better prepared to interpret scientific papers and carry out research projects (p = 0.0103 and p = 0.0240, respectively). Respondents who claimed to have participated in research or to have written papers had higher scores on theoretical scientific concepts (p = 0.0101 and p = 0.0103, respectively). However, the overall rate of right answers on questions regarding scientific knowledge was 46.1%. Therefore, a deficiency was observed in the scientific education of Brazilian otorhinolaryngologists. Such deficiency may be mitigated through participation in research.

It is not well established whether cytokine production differs in response to different clinical forms of visceral leishmaniasis (VL). In this work, we performed a cross-sectional study to investigate the plasma levels of cytokines [interferon (IFN)-γ, tumour necrosis factor (TNF)-α, interleukin (IL)-2, IL-4, IL-10 and IL-12] involved in the pathogenesis of VL in 80 subjects from VL endemic areas, including subjects with active VL, subjects with asymptomatic infection, subjects with cured VL and uninfected controls. The patients were recruited by sampling from a referral hospital and by random selection from a population-based cohort study. The results showed significant differences in the plasma concentration of all cytokines between the groups (p < 0.05). Patients with the active disease had higher plasma levels of IL-10, IL-4, INF-γ and TNF-α relative to the other groups and they produced more IL-12 than asymptomatic and cured subjects. Only the IL-2 concentration was higher in the asymptomatic and cured subjects relative to the patients with active disease (p < 0.05). Our results suggest that these cytokines can be used as markers in epidemiological studies conducted in endemic areas to distinguish between different clinical forms of VL. However, their usefulness should be confirmed in investigations conducted in other endemic areas.

RESUMO Objetivo: A exposição à educação científica durante a faculdade pode afetar o perfil do estudante, e a experiência na pesquisa pode estar associada com um melhor desempenho profissional. Hipotetizamos que o impacto da experiência na pesquisa obtida durante a graduação varia entre os currículos profissionais e entre os cursos de graduação. Métodos: Um questionário validado de múltipla escolha sobre conceitos científicos foi dado aos alunos do primeiro e quarto anos das faculdades de Medicina e Direito em uma instituição pública brasileira de ensino. Resultados: Os estudantes de Medicina participaram com mais frequência de programas de iniciação científica em relação aos estudantes de Direito, e essa tendência aumentou do primeiro ao quarto ano de faculdade. Em ambos os currículos, os alunos do quarto ano apresentaram uma maior porcentagem de acertos que os alunos do primeiro ano. A maior proporção de alunos do quarto ano definiu corretamente os conceitos de hipótese científica e teoria científica. Nas áreas de interpretação e escrita de artigos científicos, os alunos do quarto ano, em ambos os currículos, se sentiram mais confiantes do que os estudantes do primeiro ano. Embora os estudantes de Medicina tenham se sentido menos confiantes no planejamento e na realização de projetos de pesquisa que os estudantes de Direito, eles estavam mais envolvidos em atividades de pesquisa. Conclusão: A graduação em Medicina parece favorecer o desenvolvimento da maturidade crítica científica do que a graduação em Direito. A existência de políticas específicas nas escolas médicas é uma explicação razoável para a participação de estudantes de Medicina em mais atividades científicas.

ABSTRACT Objective: Exposure to science education during college may affect a student's profile, and research experience may be associated with better professional performance. We hypothesized that the impact of research experience obtained during graduate study differs among professional curricula and among graduate courses. Methods: A validated multiple-choice questionnaire concerning scientific concepts was given to students in the first and fourth years of medical and law school at a public Brazilian educational institution. Results: Medical students participated more frequently in introductory scientific programs than law students, and this trend increased from the first to the fourth years of study. In both curricula, fourth-year students displayed a higher percentage of correct answers than first-year students. A higher proportion of fourth-year students correctly defined the concepts of scientific hypothesis and scientific theory. In the areas of interpretation and writing of scientific papers, fourth-year students, in both curricula, felt more confident than first-year students. Although medical students felt less confident in planning and conducting research projects than law students, they were more involved in research activities. Conclusion: Medical graduation seems to favor the development of critical scientific maturity than law graduation. Specific policy in medical schools is a reasonable explanation for medical students’ participation in more scientific activities.
