Abstract BACKGROUND: Severe acute respiratory syndrome coronavirus 2 has several mechanisms of action related to inflammatory responses, especially in individuals diagnosed with obesity. This hyperinflammatory clinical profile resulting from the association between obesity and coronavirus disease 2019 (COVID-19) may be attenuated by regular physical activity. OBJECTIVE: The aim of this study was to review the evidence on the consequences of physical inactivity and physical activity on COVID-19 in patients with obesity. DESIGN AND SETTING: Narrative review at the Bahiana School of Medicine and Public Health in Salvador, Brazil. METHODS: We searched evidence on the association of COVID-19 with physical activity and obesity using the following keywords: “covid-19,” “physical activity,” and “obesity”. The databases used were MEDLINE (PubMed), ScienceDirect, and Virtual Health Library. Studies published from 2019 to 2021 and available in Portuguese, English, and Spanish were included. The final search was conducted on September 26, 2021. RESULTS: We identified 661 studies in the database, among which 71 were considered for inclusion in the narrative review of the molecular aspects of COVID-19 and its relationship with physical activity and obesity. CONCLUSION: This literature review enabled the perception of the relationship between the molecular mechanisms of COVID-19 and obesity. Regular physical activity had various benefits for the inflammatory condition of the studied population, highlighting moderate-intensity.

ABSTRACT Background: Tuberculosis is a worldwide public health problem and is more prevalent in specific populations, such as prisoners. The aim of this study was to analyze the epidemiological and operational indicators of tuberculosis in prisoners in a southern region of Brazil. Methods: This was a descriptive, observational study, utilizing secondary data from the Notifiable Diseases Information System on tuberculosis cases diagnosed in prisoners in the state of Rio Grande do Sul, southern Brazil, from 2014 to 2018. Prisoner data used to calculate incidence were extracted from reports by the National Penitentiary Department. Results: From 2014 to 2018, 3,557 tuberculosis cases were reported in Rio Grande do Sul prisoners. The incidence rate of tuberculosis in prisoners was 1,235/100,000 individuals in 2014 and 1,430/100,000 individuals in 2018. The proportion of new TB cases tested for HIV was high, 83.4% in this period; among those tested, 12.9% were HIV coinfected. The proportion of new cases of pulmonary tuberculosis confirmed by laboratory criteria was 52.6% in this period. In total, 18.4% of new pulmonary tuberculosis cases were initiated on directly observed treatment in this period, and 36.4% of contacts of new cases of pulmonary tuberculosis with laboratory confirmation were examined. Among retreatment pulmonary tuberculosis cases, 82.4% were laboratory-confirmed. Conclusions: Tuberculosis incidence is increasing on a per-capita and absolute basis in Rio Grande do Sul. Laboratory confirmation, HIV testing, directly observed treatment, and contact investigation rates were all low, indicating the need to improve medical and public health measures for tuberculosis control in prisons.

ABSTRACT Objective: This study aims to describe the work of the nutritionist in a psychiatric outpatient clinic of a university hospital, with patients with excess weight due to the use of certain psychiatric medications. Method: Content analysis of the clinical history and brief field notes, as complementary material. The clinical-qualitative method was applied in data collection and analysis. Results: Conversations with patients focused on their relationship with food were more effective in managing excessive weight gain than insistence on individualized and restrictive diets. The role of the family was important to strengthen the bond and favor dietary changes. Efforts to identify the emotions involved in eating, including the pleasures given by emotional, cultural, and social factors were also important. Conclusions: Nutritional care in the psychiatric field should emphasize dialogue related to the eating practices of patients. Strict dietary prescriptions can have the same unproductive effect as traditional biomedical practices if they do not consider subjective aspects of patients.

RESUMEN Objetivo: El objetivo de este estudio fue describir el trabajo del nutricionista en una clínica ambulatoria de psiquiatría de un hospital universitario, en pacientes con exceso de peso debido al uso de ciertos medicamentos psiquiátricos. Método: Análisis del contenido de la historia clínica y de breves notas de campo, como material complementario. Se aplicó el método clínico-cualitativo en la recolección y análisis de los datos. Resultados: El autor principal de este artículo, una nutricionista, indica que las conversaciones con pacientes centradas en su relación con la comida fueron más efectivas para manejar el aumento de peso excesivo do que la insistencia en las dietas individualizadas y restrictivas. El rol de la familia fue importante para fortalecer el vínculo e favorecer los cambios alimentarios. También fueran importantes los esfuerzos para identificar las emociones involucradas en la alimentación, incluidas los placeres dados por factores emocionales, culturales y sociales. Conclusiones: La atención nutricional en el campo psiquiátrico debe enfatizar el diálogo relacionado con las prácticas alimentarias de los pacientes. Las prescripciones estrictamente dietéticas pueden tener el mismo efecto improductivo que las prácticas biomédicas tradicionales si tampoco toman en cuenta los aspectos subjetivos de los pacientes.

Resumo A dificuldade de entendimento na literatura biomédica sobre a validade dos estudos qualitativos pode estar relacionada ao menor número de estudos qualitativos publicados. As críticas também vão desde a falta de profundidade teórica até discussões pouco objetivas de descobertas empíricas. O objetivo deste estudo foi explorar padrões bibliométricos e as tendências na estrutura das pesquisas qualitativas na literatura biomédica. Utilizou-se análise bibliométrica e mapeamento da literatura biomédica. O número de estudos selecionados foi 1.725. Os temas de saúde com mais publicações incluíram Gestão em Saúde (12%) e Saúde da Mulher (9,8%), enquanto os autores dos estudos tiveram afiliação acadêmica em 76 países diferentes. O tamanho da amostra mais observado foi de 11 a 20 participantes (27,13%) e o referencial da Grounded Theory (9,04%) o mais utilizado. A estruturação aprimorada de uma pesquisa qualitativa amplia a comunicação eficaz entre profissionais de saúde e pesquisadores, além de apoiar o gerenciamento de situações clínicas.

Abstract The lack of knowledge in the biomedical literature regarding the validity of qualitative studies might be related to the lower number of qualitative studies that have been published. The criticisms range from a lack of theoretical depth to the superficial discussions of empirical findings. The aim of this study was to explore the bibliometric entities and the trends in the structure of qualitative research in the biomedical literature. A bibliometric analysis and mapping of the biomedical literature were used. The number of studies selected was 1,725. The heath themes with the most publications included Health Management (12%) and Women’s Health (9.8%), while the authors of the studies had academic affiliation in 76 different countries. The sample sizes were between 11 and 20 participants (27.13%) and the Grounded Theory framework (9.04%) stood out. The improved structuring of a qualitative research extends the effective communication between health providers and researchers, and support in the management of clinical situations.

Resumo Os procedimentos da pesquisa qualitativa em saúde nem sempre são bem aplicados, principalmente na fase de análise de dados. Nosso objetivo é apresentar uma técnica sistematizada de procedimentos, passo a passo, para análise de conteúdo qualitativa no campo da saúde: A Análise de Conteúdo Clínico-Qualitativa. Nossa proposta considera que a pesquisa qualitativa aplicada ao campo da saúde, pode adquirir uma perspectiva análoga à prática clínica e visa interpretar significados expressos em relatos por meio de entrevistas ou depoimentos individuais. Esta análise faz parte do Método Clínico-Qualitativo. A revisão de literatura foi realizada por meio de: capítulo de livro, oito artigos originais e três artigos metodológicos. A técnica de Análise Clínico-Qualitativa de Conteúdo compreende sete passos: 1) Edição de material para análise; 2) leitura flutuante; 3) Construção das unidades de análise; 4) Construção de códigos de significado; 5) Refinação geral dos códigos e construção de categorias; 6) Discussão; e 7) Validade. A análise clínico-qualitativa envolve uma reflexão crítica sobre os processos realizados em cada etapa. Essa reflexão é um processo extremamente rico, se realizado coletivamente e em diálogo com outros pesquisadores com alguma proficiência em métodos qualitativos.

Abstract Qualitative Health research procedures that are not always applied, mainly in the analysis phase. Our objective is to present a systematized technique of step-by-step procedures for qualitative content analysis in the health field: Clinical-Qualitative Content Analysis. Our proposal consider that the qualitative research applied to the field of health, can acquire a perspective analogous to clinical practice and aims to interpret meanings expressed in reports through individual interviews or statements. This analysis takes part of the Clinical-Qualitative Method. The literature review was realized through: a book chapter, eight original articles and three methodological articles. The Clinical-qualitative Content Analysis technique comprises seven steps: 1) Editing material for analysis; 2) Floating reading; 3) Construction of the units of analysis; 4) Construction of codes of meaning; 5) General refining of the codes and the Construction of categories; 6) Discussion; 7) Validity. The clinical-qualitative analysis presupposes and involves a critical reflection on the processes carried out at each step. This reflection is an extremely rich process, if carried out collectively and in dialogue with other researchers with some proficiency in qualitative methods.

RESUMO A opacidade em vidro fosco é uma alteração muito frequente e pouco específica na tomografia computadorizada de tórax. Ela admite grande leque de diagnósticos diferenciais no contexto agudo, desde pneumonias virais, como as causadas pelo vírus influenza, pela doença do coronavírus 2019 e pelo citomegalovírus, até mesmo lesões de origem não infecciosa, como vaping , infarto pulmonar, hemorragia alveolar e edema pulmonar. Para essa diferenciação diagnóstica, deve-se correlacionar o vidro fosco com os demais achados nos exames de imagem, exames laboratoriais e quadro clínico do paciente. É de suma importância, no contexto de pandemia, recordar as demais patologias com os achados semelhantes aos da doença do coronavírus 2019 nos exames de imagem.

ABSTRACT Ground-glass opacity is a very frequent and unspecified finding in chest computed tomography. Therefore, it admits a wide range of differential diagnoses in the acute context, from viral pneumonias such as influenza virus, coronavirus disease 2019 and cytomegalovirus and even non-infectious lesions, such as vaping, pulmonary infarction, alveolar hemorrhage and pulmonary edema. For this diagnostic differentiation, ground glass must be correlated with other findings in imaging tests, with laboratory tests and with the patients’ clinical condition. In the context of a pandemic, it is extremely important to remember the other pathologies with similar findings to coronavirus disease 2019 in the imaging exams.

ABSTRACT It is essential for health care providers to be familiared with the full spectrum of clinical presentations of syphilis. We present herein a case of syphilide psoriasiforme, an uncommon but well recognized clinical presentation of secondary syphilis. A 46-year-old HIV-infected female patient was referred to our attention with a presumptive diagnosis of palmoplantar psoriasis. On examination, there were exuberant pinkish-red papules and plaques covered with a thick silvery scale in the palms, flexor surfaces of the wrists, and the medial longitudinal arches of the feet. Serological and histopathological analyses uncovered the diagnosis of syphilis. Clinical remission was obtained after treatment. A detailed review of the literature on syphilide psoriasiforme, including descriptions from older syphilology textsis provided. The present case report emphasizes the need for clinicians to have a heightened awareness of the varied and unusual clinical phenotypes of syphilis.

RESUMO A doença causada pelo novo coronavírus, ou COVID-19, foi descrita recentemente e tornou-se uma questão de saúde mundial. Seu diagnóstico de certeza é dado pela reação em cadeia da polimerase. A tomografia computadorizada de alta resolução, entretanto, mostra-se útil no contexto atual de pandemia, especialmente nos casos mais graves, na avaliação da extensão da doença, em possíveis diagnósticos diferenciais e na pesquisa de complicações. Em pacientes com quadro clínico suspeito e achados de imagem típicos, nos quais ainda não há resultado laboratorial ou a reação em cadeia da polimerase não se encontra disponível, ainda se discute o papel desse exame. Importante ressaltar que parte dos pacientes apresenta exames laboratoriais falsos-negativos, notadamente em casos iniciais, o que pode retardar medidas de isolamento, favorecendo a propagação da doença. Dessa forma, o conhecimento da COVID-19 e de suas manifestações nos exames de imagem é de extrema importância para os médicos envolvidos no atendimento, sejam clínicos ou radiologistas.

ABSTRACT The disease caused by the new coronavirus, or COVID-19, has been recently described and became a health issue worldwide. Its diagnosis of certainty is given by polymerase chain reaction. High-resolution computed tomography, however, is useful in the current context of pandemic, especially for the most severe cases, in assessing disease extent, possible differential diagnoses and searching complications. In patients with suspected clinical symptoms and typical imaging findings, in which there is still no laboratory test result, or polymerase chain reaction is not available, the role of this test is still discussed. In addition, it is important to note that part of the patients present false-negative laboratory tests, especially in initial cases, which can delay isolation, favoring the spread of the disease. Thus, knowledge about the COVID-19 and its imaging manifestations is extremely relevant for all physicians involved in the patient care, clinicians or radiologists.
