RESUMO Objetivo: Realizar uma revisão de escopo das metanálises publicadas sobre a doença pelo coronavírus 2019 (COVID-19), avaliando suas principais características, tendências de publicação e qualidade metodológica. Métodos: Uma busca bibliométrica foi realizada em PubMed®, Scopus e Web of Science, com foco em metanálises sobre a doença pelo COVID-19. Foram extraídos dados bibliométricos e descritivos dos artigos incluídos, e a qualidade metodológica foi avaliada usando a ferramenta A Measurement Tool to Assess Systematic Reviews. Resultados: Um total de 348 metanálises foram consideradas elegíveis. A primeira delas foi publicada em 26 de fevereiro de 2020, e, desde então, o número dessas publicações cresceu rapidamente. A maioria foi publicada em periódicos de infectologia e virologia. Grande parte é proveniente da China, seguida dos Estados Unidos, da Itália e do Reino Unido. Em média, as metanálises incluíram 23 estudos e 15.200 participantes. Em geral, a qualidade metodológica foi baixa, e apenas 8,9% delas podem ser consideradas de algum grau de confiabilidade Conclusão: Embora algumas metanálises bem conduzidas sobre a doença pelo COVID-19 tenham sido publicadas, a maioria apresenta baixa qualidade. Todos os envolvidos na abordagem da doença pelo COVID-19, incluindo formuladores de políticas, pesquisadores, editoras e periódicos, devem dar prioridade a metanálises de alta qualidade, realizadas apenas quando os dados são viáveis, e desencorajar as de baixa qualidade ou conduzidas com métodos subótimos.

ABSTRACT Objective: To carry out a scoping review of the meta-analyses published regarding about coronavirus disease 2019 (COVID-19), evaluating their main characteristics, publication trends and methodological quality. Methods: A bibliometric search was performed in PubMed®, Scopus and Web of Science, focusing on meta-analyses about COVID-2019 disease. Bibliometric and descriptive data for the included articles were extracted and the methodological quality of the included meta-analyses was evaluated using A Measurement Tool to Assess Systematic Reviews. Results: A total of 348 meta-analyses were considered eligible. The first meta-analysis about COVID-19 disease was published on February 26, 2020, and the number of meta-analyses has grown rapidly since then. Most of them were published in infectious disease and virology journals. The greatest number come from China, followed by the United States, Italy and the United Kingdom. On average, these meta-analyses included 23 studies and 15,200 participants. Overall quality was remarkably low, and only 8.9% of them could be considered as of high confidence level. Conclusion: Although well-designed meta-analyses about COVID-19 disease have already been published, the majority are of low quality. Thus, all stakeholders playing a role in COVID-19 deseases, including policy makers, researchers, publishers and journals, should prioritize well-designed meta-analyses, performed only when the background information seem suitable, and discouraging those of low quality or that use suboptimal methods.

RESUMO Objetivo: A legislação específica que regula o uso de animais em pesquisa no Brasil foi introduzida em 2008. No entanto, a opinião da população brasileira sobre o uso de animais em atividades de pesquisa e ensino ainda é desconhecida. No atual cenário brasileiro em mudança com relação à ética animal, é necessário avaliar as visões e o conhecimento da população sobre o assunto. O objetivo deste destudo foi realizar o primeiro levantamento da opinião da população brasileira sobre o uso de animais em atividades de ensino e pesquisa científica. Métodos: Analisamos os resultados de uma pesquisa com 2.115 indivíduos com 16 anos ou mais de 130 municípios das cinco macrorregiões brasileiras (Norte, Nordeste, Sul, Sudeste e Centro-Oeste). A margem de erro para toda a amostra foi de 2% dentro de um intervalo de confiança de 95%. Resultados: A pesquisa revelou que a maioria da população brasileira era favorável ao uso de animais em pesquisas, principalmente para fins médicos. Diferentes pontos de vista, dependendo da natureza da pesquisa, também foram identificados. Além disso, aproximadamente 80% dos entrevistados eram favoráveis ao monitoramento frequente de laboratórios e instalações de animais. Conclusão: A opinião da população brasileira está dividida com relação ao uso de animais em pesquisa e ensino científicos. Essa divisão expõe um entendimento limitado da importância das ciências básicas e destaca a necessidade de uma melhor comunicação entre a comunidade científica e a população em geral. Outras ações para alcançar as melhorias desejadas no bem-estar animal são discutidas.

ABSTRACT Objective: Specific legislation regulating the use of animals in research in Brazil was introduced in 2008. However, the viewpoint of the Brazilian population regarding the use of animals in research and teaching activities remains largely unknown. Investigation of the public viewpoint on and understanding of the topic is required given the current shifts in the animal ethics scenario in Brazil. The objective of this study was to provide the first insight into the Brazilian population viewpoint on the use of animals in scientific research and teaching activities. Methods: Data collected in a survey involving 2,115 individuals aged 16 years or older and residing in 130 municipalities distributed across the five Brazilian macroregions (North, Northeast, South, Southeast, and Midwest) were analyzed. The margin of error for entire sample was set at 2%, with a 95% confidence interval. Results: This survey revealed that most Brazilian citizens are in favor of the use animals in research, particularly for medical purposes. Different views depending on the nature of research were identified. Approximately 80% of respondents were also in favor of frequent oversight of laboratories and animal facilities. Conclusion: Survey findings indicate that the opinion of the Brazilian population is divided when it comes to the use of animals in scientific research and teaching. Divided opinions expose a limited understanding of the importance of basic sciences and emphasizes the need for improved communication between the scientific community and the general population. Further strategies aimed to promote animal welfare are discussed.

Resumo O uso de animais para fins didáticos e de pesquisa requer cuidados específicos. Atualmente, vigora no Brasil a Lei 11.794/2008, que rege parâmetros legais de manejo e conduta neste caso. Esta lei foi acompanhada da instalação ou adequação de comissões de ética em instituições que utilizam animais para ensino e investigação, bem como da criação do Conselho Nacional de Controle de Experimentação Animal. No entanto, apesar dos avanços, especialmente na legislação, ainda não foi consolidada nenhuma grande mudança de comportamento de pesquisadores e alunos de graduação que manuseiam animais em laboratório. A divulgação de informações deixa a desejar, e a prática acaba por repercutir a carência de reflexão ética. Este artigo busca averiguar o atual conhecimento bioético de alunos de graduação e professores com o objetivo de estimular mudanças de conduta. Aprovado CEP-Unioeste CAAE 8563417.8.0000.0107

Abstract Used for education and research, laboratory animals require special care on their handling. Brazilian Law 11,794/2008 establishes the legal parameters for animal manipulation and welfare. It was accompanied by the obligatory installation of the Institutional Ethics Committees on the Use of Animals and the creation of the National Council for Animal Experimentation Control. There have been advances in the field of animal bioethics legislation. However, considering the behavior of those who handle the animals in laboratory environment, especially undergraduate students, these advances are insufficient: the information does not reach them and their attitudes remain in need of ethical reflection. This article seeks to investigate the current bioethical knowledge of undergraduate students and teachers in order to stimulate changes in conduct. Aprovado CEP-Unioeste CAAE: 78563417.8.0000.0107

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Os aspectos clínicos da relação materno-infantil e assuntos a eles associados são suficientemente bem estudados e conhecidos, e de grande importância à prática médica. Contudo, algumas abordagens de pesquisa, nesse contexto, não podem ser feitas em seres humanos de forma plausível, devido a implicações éticas e ao potencial dano à saúde, tanto da mãe quanto da criança. Os estudos sobre comportamento materno em animais apresentam importância evidente em áreas clínicas, como psiquiatria e psicologia, particularmente quando considerados temas como relação materno-infantil, depressão pós-parto, desenvolvimento cognitivo e comportamental infantil, entre outros. Portanto, este ensaio teórico chama atenção para a aplicabilidade clínica de estudos sobre comportamento materno feitos em animais de experimentação em psicobiologia, considerando uma perspectiva translacional.

Clinical aspects of the mother-infant relationship and related issues are well studied and very relevant to medical practice. Nevertheless, some approaches in this context cannot plausibly be investigated in humans due to their ethical implications and to the potential harm to the mother's and child's health. Studies on maternal behavior in animals have evident importance to some clinical fields, such as psychiatry and psychology, particularly considering topics, including mother-infant relationship, postpartum depression, cognitive and behavioral development of children, and associated issues. Hence, this theoretical article draws attention to the clinical applicability of studies about maternal behavior in animals to psychobiology, taking into account a translational perspective.

Abstract: En | Text: En | PDF: En

OBJECTIVE: To assess the effect of passive body heating on the sleep patterns of patients with fibromyalgia. METHODS: Six menopausal women diagnosed with fibromyalgia according to the criteria determined by the American College of Rheumatology were included. All women underwent passive immersion in a warm bath at a temperature of 36 ±1 °C for 15 sessions of 30 minutes each over a period of three weeks. Their sleep patterns were assessed by polysomnography at the following time-points: pre-intervention (baseline), the first day of the intervention (acute), the last day of the intervention (chronic), and three weeks after the end of the intervention (follow-up). Core body temperature was evaluated by a thermistor pill during the baseline, acute, chronic, and follow-up periods. The impact of this treatment on fibromyalgia was assessed via a specific questionnaire termed the Fibromyalgia Impact Questionnaire. RESULTS: Sleep latency, rapid eye movement sleep latency and slow wave sleep were significantly reduced in the chronic and acute conditions compared with baseline. Sleep efficiency was significantly increased during the chronic condition, and the awakening index was reduced at the chronic and follow-up time points relative to the baseline values. No significant differences were observed in total sleep time, time in sleep stages 1 or 2 or rapid eye movement sleep percentage. The core body temperature and Fibromyalgia Impact Questionnaire responses did not significantly change over the course of the study. CONCLUSION: Passive body heating had a positive effect on the sleep patterns of women with fibromyalgia.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

A privação de sono é uma condição cada vez mais observada na sociedade moderna, resultando em diversos efeitos neurocomportamentais. Um dos principais efeitos comportamentais dessa condição é a proeminência de estados ansiosos. Diversos estudos têm demonstrado, com sucesso, a relação entre privação de sono e ansiedade na pesquisa clínica. Quanto à experimentação básica, diversos modelos têm sido eficientemente empregados na avaliação do comportamento do tipo ansioso. Todavia, a mesma eficácia não é encontrada nos estudos básicos, que abordam a relação entre privação de sono paradoxal e ansiedade. A maioria dos estudos que aborda essa relação em modelos animais não apresenta resultados passíveis de extrapolação à prática clínica, e isso se deve basicamente a dois motivos: inconsistência entre resultados e falta de replicabilidade em relação a estudos clínicos. Ressalta-se que o uso de modelo animais é extremamente útil, sobretudo em condições experimentais que não podem ser ética ou plausivelmente abordadas em seres humanos. Desse modo, o presente ensaio teórico busca avaliar, de modo sucinto e crítico, a aplicabilidade dos modelos animais de privação de sono, sob uma perspectiva translacional.

Sleep deprivation is a condition that is more and more observed in modern society bringing various neurobehavioral effects, being anxious states one of the main problems. Many studies have successfully demonstrated the relationship between sleep deprivation and anxiety in clinical research. As to basic experimentation, various models have been efficiently used in order to evaluate an anxious behavior. However, the same efficacy is not found on basic studies that deal with the relationship between paradoxical sleep and anxiety. The great majority of studies which approach this matter in animal models do not present results that may be applied to clinical practice and this is basically due to two reasons: inconsistency among results and lack of replicability as related to clinical studies. It has to be emphasized that the use of animal models is extremely useful, mainly under experimental conditions which cannot be ethically or plausibly be approached in human beings. So, the present theoretical assay tries to evaluate in a brief and critical manner the applicability of animal models in sleep deprivation under a translational perspective.

Abstract: En | Text: En | PDF: En

Patients who have suffered burns frequently experience psychological consequences, among which anxiety disorders are prominent. Benzodiazepines are commonly administered to treat these symptoms. The effects of benzodiazepines on healing may not be direct but rather are modulated by alterations of the sleep architecture. This hypothesis is supported by studies that demonstrate the effects of benzodiazepines on the immune system and the inflammatory profile under both normal sleep conditions and during sleep deprivation, particularly rapid eye movement sleep deprivation.

Abstract: En | Text: En | PDF: En

OBJECTIVES: The purpose of this study was to determine the paired consequences of food restriction and paradoxical sleep deprivation on lipid profile and spontaneous glucose levels in male rats. METHOD: Food restriction began at weaning, with 6 g of food being provided per day, which was subsequently increased by 1 g per week until reaching 15 g per day by the eighth week. At adulthood, both rats subjected to food restriction and those fed ad libitum were exposed to paradoxical sleep deprivation for 96 h or were maintained in their home-cage groups. RESULTS: Animals subjected to food restriction exhibited a significant increase in high-density lipoprotein levels compared to animals that were given free access to food. After the paradoxical sleep deprivation period, the foodrestricted animals demonstrated reduced concentrations of high-density lipoprotein relative to their respective controls, although the values for the food-restricted animals after sleep deprivation were still higher than those for the ad libitum group. The concentration of low-density lipoproteins was significantly increased in sleep-deprived animals fed the ad libitum diet. The levels of triglycerides, very low-density lipoproteins, and glucose in foodrestricted animals were each decreased compared to both ad libitum groups. CONCLUSION: These results may help to illustrate the mechanisms underlying the relationship between sleep curtailment and metabolism and may suggest that, regardless of sleep deprivation, dietary restriction can minimize alterations in parameters related to cardiovascular risk.
