La Pregunta de Investigación y su Asociación con los Niveles de Evidencia y Grados de Recomendación en Estudios de Investigación Clínica / The Research Question and its Association with the Levels of Evidence and Grades of Recommendation in Clinical Research Studies

La mayoría de las preguntas de investigación (PI), conducirán a un proyecto que apunta a generar nuevo conocimiento, sin embargo el escenario, la población a estudio y la metodología pueden ser muy diferentes, lo que determinará que los resultados obtenidos y por ende, el nivel de evidencia (NE) y el grado de recomendación (GR) puedan variar notablemente. El objetivo de este artículo fue proporcionar recomendaciones para formular una PI asociada al NE y respectivos GR que se pueden desprender a partir de los resultados generados. Este artículo entregará algunos conocimientos sobre la PI y su relación con los NE y GR de la evidencia generada a partir de resultados obtenidos por un proceso de investigación en diferentes escenarios de investigación.

SUMMARY: Most research questions (RQ) will lead to a project that aims to generate new knowledge. However, the setting, study population and methodology may be very different, which will determine the results obtained and therefore, the level of evidence (LOE) and the grade of recommendation (GOR) may vary significantly. The aim of this study was to provide recommendations to formulate a RQ associated with the LOE and respective GOR that can be derived from the generated results. This article will provide some knowledge about the RQ and its relationship with the LEO and GOR of the generated evidence from results obtained by a research process in different research scenarios.

Efficiency and comparability of using new evidence platforms for updating recommendations: experience with a type-2 diabetes guideline in Colombia / Eficiencia y comparabilidad del uso de nuevas plataformas de evidencia para la actualización de recomendaciones: experiencia con una guía de diabetes tipo 2 en Colombia

INTRODUCTION: Updating recommendations for guidelines requires a comprehensive and efficient literature search. Although new information platforms are available for developing groups, their relative contributions to this purpose remain uncertain. METHODS: As part of a review/update of eight selected evidence-based recommendationsfor type 2 diabetes, we evaluated the following five literature search approaches (targeting systematic reviews, using predetermined criteria): PubMed for MEDLINE, Epistemonikos database basic search, Epistemonikos database using a structured search strategy, Living overview of evidence (L.OVE) platform, and TRIP database. Three reviewers independently classified the retrieved references as definitely eligible, probably eligible, or not eligible. Those falling in the same "definitely" categories for all reviewers were labelled as "true" positives/negatives. The rest went to re-assessment and if found eligible/not eligible by consensus became "false" negatives/positives, respectively. We described the yield for each approach and computed "diagnostic accuracy" measures and agreement statistics. RESULTS: Altogether, the five approaches identified 318 to 505 references for the eight recommendations, from which reviewers considered 4.2 to 9.4% eligible after the two rounds. While Pubmed outperformed the other approaches (diagnostic odds ratio 12.5 versus 2.6 to 5.3), no single search approach returned eligible references for all recommendations. Individually, searches found up to 40% of all eligible references (n = 71), and no combination of any three approaches could find over 80% of them. Kappa statistics for retrieval between searches were very poor (9 out of 10 paired comparisons did not surpass the chance-expected agreement). CONCLUSION: Among the information platforms assessed, PubMed appeared to be more efficient in updating this set of recommendations. However, the very poor agreement among search approaches in the reference yield demands that developing groups add information from several (probably more than three) sources for this purpose. Further research is needed to replicate our findings and enhance our understanding of how to efficiently update recommendations.

INTRODUCCIÓN: La actualización de recomendaciones de las guías de práctica clínica requiere búsquedas bibliográficas exhaustivas y eficientes. Aunque están disponibles nuevas plataformas de información para grupos desarrolladores, su contribución a este propósito sigue siendo incierta. MÉTODOS: Como parte de una revisión/actualización de 8 recomendaciones basadas en evidencia seleccionadas sobre diabetes tipo 2, evaluamos las siguientes cinco aproximaciones de búsqueda bibliográfica (dirigidas a revisiones sistemáticas, utilizando criterios predeterminados): PubMed para MEDLINE; Epistemonikos utilizando una búsqueda básica; Epistemonikos utilizando una estrategia de búsqueda estructurada; plataforma (L.OVE) y TRIP . Tres revisores clasificaron de forma independiente las referencias recuperadas como definitivamente o probablemente elegibles/no elegibles. Aquellas clasificadas en las mismas categorías "definitivas" para todos los revisores, se etiquetaron como "verdaderas" positivas/negativas. El resto se sometieron a una nueva evaluación y, si se consideraban por consenso elegibles/no elegibles, se convirtieron en "falsos" negativos/positivos, respectivamente. Describimos el rendimiento de cada aproximación, junto a sus medidas de "precisión diagnóstica" y las estadísticas de acuerdo. RESULTADOS: En conjunto, las cinco aproximaciones identificaron 318-505 referencias para las 8 recomendaciones, de las cuales los revisores consideraron elegibles el 4,2 a 9,4% tras las dos rondas. Mientras que Pubmed superó a las otras aproximaciones (odds ratio de diagnóstico 12,5 versus 2,6 a 53), ninguna aproximación de búsqueda identificó por sí misma referencias elegibles para todas las recomendaciones. Individualmente, las búsquedas identificaron hasta el 40% de todas las referencias elegibles (n=71), y ninguna combinación de cualquiera de los tres enfoques pudo identificar más del 80% de ellas. Las estadísticas Kappa para la recuperación entre búsquedas fueron muy pobres (9 de cada 10 comparaciones pareadas no superaron el acuerdo esperado por azar). CONCLUSIONES: Entre las plataformas de información evaluadas, Pubmed parece ser la más eficiente para actualizar este conjunto de recomendaciones. Sin embargo, la escasa concordancia en el rendimiento de las referencias exige que los grupos desarrolladores incorporen información de varias fuentes (probablemente más de tres) para este fin. Es necesario seguir investigando para replicar nuestros hallazgos y mejorar nuestra comprensión de cómo actualizar recomendaciones de forma eficiente.

Evaluación de la calidad de guías de práctica clínica para el tratamiento de adultos con COVID-19 leve o moderada, utilizando la herramienta AGREE II / Assessment of the quality of clinical practice guidelines on the treatment of adults with mild or moderate COVID-19, using the AGREE II tool

INTRODUCCIÓN: Varias guías de práctica clínica para el tratamiento de la COVID-19 se han desarrollado durante los dos últimos años de pandemia, sin embargo, su calidad metodológica es poco clara. OBJETIVO: Realizar una evaluación sistemática de la calidad de las guías de práctica clínica publicadas entre 2021 y octubre de 2022 para el tratamiento de la COVID-19, utilizando la herramienta AGREE II, e identificar las recomendaciones formuladas en dichas guías. JUSTIFICACIÓN: Durante la pandemia, surgieron múltiples guías, pero la claridad so-bre su calidad metodológica fue limitada. MÉTODOS: Se realizó una búsqueda sistemática de guías de práctica clínica sobre el tratamiento para la COVID-19 leve o moderada utilizando metabuscadores como Epistemonikos y Trip Database, y sitios web de organizaciones de sa-lud. Las guías seleccionadas fueron evaluadas con el instrumento AGREE II. RESULTADOS: Se evaluaron 11 GPC, presentando altas puntuaciones en los dominios de alcance y propósito (98,74 %), participación de los implicados (97,22 %), rigor en la elaboración (92 %), claridad de presentación (100 %), aplicabilidad (85,61 %), e independencia editorial (100 %). Aunque la ca-lidad general de las guías fue alta, se identificó la necesidad de mejorar en los aspectos de rigor en la elaboración y aplicabilidad de las recomendaciones. CONCLUSIONES: Encontramos que la calidad de las guías de práctica clínica evaluadas, en su mayoría es alta y, por lo tanto, son recomendables, aunque reconocemos la necesidad de mejorar la descripción de los dominios de rigor en la elaboración y aplicabilidad de las recomendaciones.

INTRODUCTION: Several clinical practice guidelines for the management of COVID-19 have been developed during the last two years of the pandemic, but their methodological quality is unclear. OBJECTIVE: To systematically assess the quality of clinical practice guidelines for the treatment of COVID-19 published between 2021 and October 2022 using the AGREE II tool, and to identify the recommendations made in these guidelines. JUSTIFICATION: During the pandemic, many guidelines were published, but clarity about their methodological quality was limited. METHODS: A systematic search for clinical practice guidelines on the management of mild-to-moderate COVID-19 was performed using meta-search engines such as Epistemoni-kos and Trip Database, as well as health organization websites. The selected guidelines were appraised using the AGREE II instrument. RESULTS: Eleven clinical practice guidelines (CPGs) were evaluated, showing high scores in the domains of scope and purpose (98.74%), stakehol-der involvement (97.22%), rigor of development (92%), clarity of presentation (100%), applica-bility (85.61%), and editorial independence (100%). Although the overall quality of the guidelines was high, there was identified a need for improvement in the areas of rigor of development and applicability of the recommendations. CONCLUSIONS: We found that the quality of the evalua-ted clinical practice guidelines is predominantly high, and therefore, they are recommendable. However, we recognize the need to improve the descriptions of the domains of rigor of develop-ment and applicability of the recommendations,

Ciência e impossível: uma perquisição psicanalítica do evidence-based / Science and impossible: an psychoanalytic investigation of evidence-based

Resumo: Partindo da leitura lacaniana de que a ascensão do discurso científico produziu uma mudança na posição do médico, interrogam-se os efeitos do estabelecimento do evidence-based como paradigma para a prática médica. Se a inferência estatística exemplifica a convergência entre matematização e objetividade, lança-se mão de uma vinheta relativa à prática em um ambulatório de Distúrbios da Diferenciação Sexual para interpelar os impasses relativos à designação do sexo nesses casos. Pretende-se evidenciar a diferença entre a práxis da psicanálise e a abordagem médica que se orienta na direção da universalização, situando assim seus limites frente ao real do sexo.

Abstract: From the Lacanian interpretation that the rise of scientific discourse produced a change in the physician's position, the effects of the establishment of evidence-based as a paradigm for medical practice are examined. If the statistical inference exemplifies the convergence between mathematization and objectivity, an example related to the practice in a Sexual Differentiation Disorders clinic is used to question the impasses related to the designation of sex in these cases. It is intended to highlight the difference between the praxis of psychoanalysis and the medical approach that is oriented towards universalization, thus placing its limits related to the real of sex.

Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: History and scenario of patient blood management in the world and in Brazil

Abstract Patient Blood Management (PBM) is a multidimensional approach that seeks to optimize the use of blood and its components in patients. This matter emerged as a response to the need to reduce unnecessary exposure to blood transfusions and their potential risks. In the past, blood transfusion was often overused resulting in complications and high costs. The advent of Patient Blood Management has caused a paradigm shift, highlighting anemia prevention, bleeding control and maximizing the production of blood cells by the organism itself. Patient Blood Management guidelines include the early identification of anemia, strategies to minimize blood loss during surgery, intraoperative blood conservation techniques, preoperative hemoglobin optimization and evidence-based approaches to the rational use of blood transfusions. Aiming to improve clinical outcomes, decrease transfusion-related complications and reduce associated costs, this multidisciplinary approach counts on doctors, nurses, pharmacists and other healthcare professionals. Based on research and clinical evidence, Patient Blood Management continues to evolve thereby promoting safer, more effective patient-centered practices. Its implementation has proven beneficial in various medical contexts thereby contributing to improvements in the quality of care provided to patients. Our goal with this Consensus is to present readers with a broad and diverse view of Patient Blood Management so that they have the building blocks to implement this new technique.

Consensus of the Brazilian association of hematology, hemotherapy and cellular therapy on patient blood management: Antifibrinolytics

Abstract The use of strategies to reduce blood loss and transfusions is essential in the treatment of surgical patients, including in complex cardiac surgeries and those that use cardiopulmonary bypass. Antifibrinolytics, such as epsilon-aminocaproic acid (EACA) and tranexamic acid (TXA), are widely used in these procedures, as well as in other types of surgeries. These medicines are included in the World Health Organization (WHO) list of 'essential medicines'. Scientific evidence demonstrates the effectiveness of EACA in reducing bleeding and the need for transfusions in heart surgery. EACA is highly recommended for use in heart surgery by the American Society of Anesthesiology Task Force on Perioperative Blood Management. Regarding the safety of EACA, there is no robust evidence of any significant thrombotic potential. TXA has also been shown to be effective in reducing the use of blood transfusions in cardiac and non-cardiac surgeries and is considered safer than other antifibrinolytic agents. There is no evidence of any increased risk of thromboembolic events with TXA, but doses greater than 2 g per day have been associated with an increased risk of seizures. It is also important to adjust the dose in patients with renal impairment. In conclusion, antifibrinolytics, such as EACA and TXA, are effective in reducing blood loss and transfusion use in cardiac and non-cardiac surgeries, without causing serious adverse effects.

Assessing the level of evidence of presented studies at the Brazilian Congress of Coloproctology

Introduction: Scientific studies in Brazil grew around 10.7% compared to previous years. However, the level of quality of evidence has been decreasing. The aim in our study is to examine the meeting abstracts of the Brazilian congress of coloproctology and analyze the level of evidence in trends and variables. Methods: A descriptive bibliometric study, working with secondary data to review scientific abstracts in the annals of the coloproctology congress from 2015 to 2019. Results: A total of 1756 abstracts of the Brazilian Congress of Coloproctology were analyzed for 5 years (2015-2019). There was a higher trend of abstracts presented with lower levels of evidence (level of evidence 5: 52.3% and 3: 30%), being the majority composed of case reports (49.4%) and retrospective studies (30.4%). The last two years analyzed (2018: 55.2% and 2019: 59.3%) had a predominance above average of case reports. From 2017 to 2019 there was a significant decrease in the number of level 2 evidence studies (18.10%,11.80% and 5.50%), while the number of studies with level 5 evidence showed an increase (45.60%, 56.60% and 61.40%). Statistical analysis occurred in only 17%, with an important decrease for the last two years (2018: 13.6%; 2019: 12.1%). Conclusions: Although the data of this study is from the Brazilian coloproctology point of view, they are important for the global scientific community, as they allow a quantitative evaluation of the relative contribution from the level of evidence of Brazilian coloproctology researchers to the scientific scenario.

Impact of the "Journal Club" activity among medical students' knowledge of scientific methodology / Avaliação de impacto da atividade "journal club" no conhecimento de metodologia científica entre os estudantes de medicina

Introduction: The Journal Club is an environment for exchanging information within the medical context concerning updated literature and evidence-based medicine. Considering the importance of constantly updating the acquired knowledge and scenarios of social isolation imposed by the COVID-19 pandemic, the Journal Club event was held virtually, aiming to expand the understanding of the scientific methodology among medical students by understanding the differences among each type of evidence pyramid study by reading and discussing scientific articles. Methodology: An analytical, prospective, and cross-sectional study was conducted in October 2021. The Journal Club event took place in nine classes where each type of evidence pyramid study was addressed. The sample included 20 medical students. A questionnaire was used at the beginning and end of the event to assess the participants' knowledge from the classes taught and was divided into two parts: participant identification data and 19 questions regarding the types of studies present on the pyramid of evidence. Results: It was found that after the pre- and post-event analysis of the questionnaire among the 19 questions, correct answers increased in 17, among which 3 obtained a statistically significant value: questions 1 (p = 0.031), 15 (p = 0.039), and 18 (p = 0.016). Discussion: An increase in the number of correct answers was noted between pre- and post-classes, which may indicate an improved understanding of the subject among students. Furthermore, the study demonstrated that the students had little involvement in scientific research (only 25% had ever been involved in a project). Conclu-sion: Based on the analysis of the participants' performance in the pre- and post-event questionnaires, it can be concluded that the medical students were able to expand their knowledge of scientific methodology (AU).

Introdução: O Journal Club é um ambiente para troca de informações dentro do contexto médico, diante de uma literatura atualizada e medicina baseada em evidências. Tendo em vista a importância da atualização constante de conhecimentos adquiridos e o cenário de isolamento social imposto pela pandemia da COVID-19, o evento Journal Club foi realizado virtualmente, com o objetivo de ampliar o entendimento sobre metodologia científica entre estudantes de medicina por meio da compreensão das diferenças de cada tipo de estudo da pirâmide de evidências a partir da leitura e discussão de artigos científicos. Metodologia: Estudo analítico, prospectivo e transversal realizado em outubro de 2021. O evento Journal Club ocorreu em nove aulas onde foram abordados cada tipo de estudo da pirâmide de evidência. A amostra foi composta por 20 estudantes de medicina. Um questionário foi aplicado no início e ao final do evento para avaliar o conhecimento dos participantes a partir das aulas ministradas, e foi dividido em duas partes, a primeira com dados de identificação do participante e a segunda com 19 questões sobre os tipos de estudos presentes na pirâmide de evidência. Resultados: Observou-se que, após a análise do questionário pré e pós-evento, dentre as 19 questões realizadas, houve um aumento de acertos em 17 entre as quais 3 obtiveram um valor estatístico significativo: questões 1 (p= 0,031), 15 (p=0,039) e 18 (p= 0,016). Discussão: Notou-se aumento dos acertos de questões entre o pré e pós-aulas, podendo indicar uma melhora no entendimento por parte dos acadêmicos acerca do assunto. Além disso, o estudo mostrou uma baixa atuação dos acadêmicos em pesquisas científicas (apenas 25% já se envolveram em algum projeto). Conclusão: A partir da análise do desempenho dos participantes nos questionários pré e pós-evento é possível afirmar que os estudantes de medicina conseguiram ampliar seu conhecimento sobre metodologia científica (AU).

Prática baseada em evidências: incorporando pesquisas na prática clínica / Evidence-based practice: incorporating research into clinical practice

Evidências Científicas (ECs) configuram-se como "resultados de pesquisas científicas", realizadas através de procedimentos que incorporaram critérios de validade, isto é, viabilidade (F-feasibility), adequação (A-appropriateness), significado (M-meaning) e efetividade (E-effectiveness) das práticas de saúde, levando-se em conta todasas possíveis fontes de vieses. O termo Prática Baseada em Evidências (PBE) foi cunhado entre as décadas de 70 e 80, sendo originário do movimento da Medicina Baseada em Evidências (MBE), quando foi proposta uma hierarquia dos níveis de ECs, de modo a direcionar a busca das melhores ECs disponíveis para a tomada de decisões na prática clínica. No ano de 2002, enfermeiras engajadas na prática clínica e em pesquisa estabeleceram um modelo para implementação da PBE, o "Advancing Research and Clinical Practice through Close Collaboration(ARCC)", com o intuito de aprimorar e melhor integrar a pesquisa à prática clínica, atrelando aos cuidados de saúde locorregionais e nacionais. Assim, a PBE consiste em uma abordagem ancorada na resolução de problemas para prover o cuidado em saúde que integra as melhores ECs disponíveis provenientes de estudos bem delineados, e combina com as preferências e valores do paciente e a expertisedo profissional de saúde. Para a implementação da PBE na prática clínica, épreciso que o profissional de saúde mantenha a atitude questionadora de modo a transformar a prática clínica. O fio condutor da PBE éa utilização de resultados de pesquisas na prática. Nesse sentido, o movimento de Enfermagem Baseada em Evidências emerge como um elo que interliga as melhores ECs e sua aplicação na prática clínica, primando pela tomada de decisão para um cuidado cientificamente qualificado e seguro. Na prática do enfermeiro, a aplicação da PBE consiste em sete passos: 1) elaboração da questão clínica; 2) busca de ECs; 3) avaliação crítica das ECs recuperadas no processo de busca; 4) tomada de decisões com base nas melhores ECs; 5) avaliação dos resultados da decisão clínica a ser implementada; 6) mudanças com base nas ECs disponíveis; 7) disseminação dos resultados da decisão clínica/mudança da práxis.

Scientific Evidence (ScE) is configured as "results of scientific research", carried out through procedures that incorporated validity criteria, that is, feasibility (F), appropriateness (A), meaning (M) and effectiveness (E) of health practices, taking into consideration all possible sources of bias.The term Evidence-Based Practice (EBP) was created between the 1970s and 1980s, originating from the Evidence-Based Medicine (EBM) movement, where a hierarchy of levels of ScE was proposed, in order to direct the search for best available ScE for decision-making in clinical practice.In 2002, nurses engaged in clinical practice and research established a model for the implementation of EBP, the "Advancing Research and Clinical Practice through Close Collaboration (ARCC)", with the aim of improving and better integratingresearch into clinical practice, linking local and national health care actions. Thus, EBP consists of a problem-solving approach to providing health care actions that integrate the best available ScE from well-designed studies, and combines with the patient's preferences and values and the health professional's expertise. In order to consolidate the implementation of EBP in clinical practice, the health professional must maintain a questioning attitude in such a way as to transform clinical practice. The guiding principle of EBP is the use of research results in practice. In this sense, the Evidence-Based Nursing movement emerges as a link that connects the best ScE and its application in clinical practice, focusing on decision-making for care scientifically qualified and safe. In nursing practice, the application of EBP consists of seven steps: 1) elaboration of the clinical question; 2) search for ScE; 3) critical evaluation of the ScE retrieved in the search process; 4) decision-making based on the best ScE; 5) evaluation of the results of the clinical decision to be implemented; 6) changes based on the available ScE; 7) dissemination of the results of the clinical decision/praxis change.

Clinical, epidemiological, and laboratory profiles of bacterial infection or colonization among patients hospitalized in COVID-19 and non-COVID-19 intensive care units (ICUs) in Southeast Pará / Perfis clínico, epidemiológico e laboratorial de infecção ou colonização bacteriana em pacientes internados em unidades de terapia intensiva (UTIs) COVID-19 e não COVID-19 no sudeste do Pará

Objectives: To compare the clinical, epidemiological, and laboratory profiles of bacterial infection or colonization among patients hospitalized in COVID-19 and non-COVID-19 intensive care units (ICUs) in Southeast Pará, Brazil. Methods:This was a retrospective analytical study based on the analyses of electronic medical records and microbiological reports of patients admitted to the ICU of a regional hospital located in Pará in the Brazilian Amazon due to complications associated with COVID-19 and other causes from March 2020 to December 2021. The sample consisted of data from the medical records of 343 patients collected after approval by the ethics and research committee (opinion number 5281433) was granted. The data extracted from the bacteriological and antibiogram culture reports were analyzed to characterize the clinical-epidemiological profile of the patients. The data were transferred and tabulated in Microsoft Excel 2019 to conduct a descriptive analysis, and the associated statistical analyses were performed using Stata 17.0 statistical soft-ware. Results: Of the total patients, 59.5% were hospitalized in the COVID-19 ICU and 40.5% were hospitalized in the non-COVID-19 ICU. Most individuals admitted to the COVID-19 ICU and non-COVID-19 ICU were aged between 66 and 78 years and between 54 and 66 years, respectively. The hospitalization duration in the COVID-19 ICU was fewer than 15 days, whereas that in the non-COVID-19 ICU was 15 to 30 days. Deaths were more frequent in the Covid-19 ICU compared to the non-Covid-19 ICU (64% versus 41%). In contrast, hospital discharge was more frequent in the non-Covid-19 ICU (58.3% versus 34.8%).The most prevalent comorbidity in both ICUs was circulatory system disease. Gram-negative bacteria were the most frequent etiological agent in both groups and were present in 63.1% of the cultures analyzed. Regarding the phenotypic profile of resistance, carbapenemase production was detected in 43.0% of the cultures analyzed. Multidrug resistance against antimicrobial drugs was more frequent in the non-COVID-19 ICU (55.7%). Most of the antimicrobial drug prescriptions for were empirical. Conclusions: The recurrence of secondary infections and bacterial colonization in both COVID-19 and non-COVID-19 ICU patients should not be underestimated. The clinical, microbiological, and bacterial resistance profiles elucidated in this study highlight the need to develop and implement holistic and assertive strategies to control and mitigate these problems. Which will contribute to an improved prognosis for patients and quality of life patients (AU).

Objetivos: Comparar o perfil clínico, epidemiológico e laboratorial das infecções ou colonizações bacterianas entre pacientes internados em UTI COVID-19 e não-COVID-19 no Sudeste do Pará, Brasil. Métodos: Trata-se de um estudo analítico retrospectivo baseado na análise de prontuários eletrônicos e laudos microbiológicos de pacientes internados em um hospital regional localizado no Pará, na Amazônia brasileira, devido a complicações associadas à COVID-19 e outras causas no período de março de 2020 a dezembro de 2021. A amostra foi constituída por dados dos prontuários de 343 pacientes coletados após aprovação pelo Comitê de ética em Pesquisa (parecer número 5281433). Os dados extraídos dos laudos de cultura bacteriológica e antibiograma foram analisados para caracterizar o perfil clínico-epidemiológico dos pacientes. Foram realizadas análises descritivas e inferenciais utilizando o Stata 17.0 statistical software. Resultados: Do total de pacientes, 59,5% estavam internados na UTI COVID-19 e 40,5% na UTI não-COVID-19. A maioria dos indivíduos apresentavam idades entre 54 e 78. O tempo de internação na UTI COVID-19 foi inferior a 15 dias, enquanto na UTI não-CO-VID-19 foi de 15 a 30 dias. Os óbitos foram mais frequentes na UTI Covid-19 em relação à UTI não-Covid-19 (64% versus 41%). Em contrapartida, a alta hospitalar foi mais frequente na UTI não Covid-19 (58,3% versus 34,8%). A comorbidade mais prevalente em ambas as UTIs foi a doença do aparelho circulatório. As bactérias Gram-negativas foram os agentes etiológicos mais frequentes em ambos os grupos e estiveram presentes em 63,1% das culturas analisadas. Em relação ao perfil fenotípico de resistência, a produção de carbapenemase foi detectada em 43,0% das culturas analisadas. A multirresistência aos antimicrobianos foi mais frequente na UTI não COVID-19 (55,7%). A maioria das prescrições de antimicrobianos foram empíricas. Conclusões: A recorrência de infecções secundárias e colonizações bacterianas em pacientes com COVID-19 e não COVID-19 em UTIs não devem ser subestimadas. Os perfis de resistência bacteriana elucidados neste estudo destacam a necessidade da implementação de estratégias holísticas e assertivas visando o controle e mitigação dessa problemática, o que contribuirá para a melhoria do prognóstico, bem como, a qualidade e segurança dos paciente (AU).

Novas tendências na promoção da atividade física para a população / New trends in promoting physical activity for the population

As recomendações de atividade física para a população foram avançando desde os tempos em que somente a atividade intensa e contínua de pelo menos uma hora de duração eram as indicadas, passando para moderadas de pelo menos 30 minutos, diminuição do tempo sentado, até as evidências de que "Todo Passo ou Movimento Conta". Chegamos agora às propostas de atividade intensa, mas de curta ou curtíssima duração; que facilitariam a incorporação ao estilo de vida. As primeiras evidências são cercadas de grande entusiasmo, podendo se tornar em uma nova tendência de prescrição, mas requerem novos estudos para passarem a fazer parte do rol oficial das recomendações.

¿Cuántos Tipos de Revisiones de la Literatura Existen? Enumeración, Descripción y Clasificación. Revisión Cualitativa / How Many Types of Literature Reviews are There? Listings, Description and Classification

La expansión y consolidación de la práctica clínica basada en la evidencia ha llevado entre otras, a la necesidad de realizar una variedad cada vez mayor de tipos de revisión de la literatura científica; lo que permite avanzar en el conocimiento y comprender la amplitud de la investigación sobre un tema de interés, teniendo en cuenta que una de las propiedades del conocimiento es su carácter acumulativo. Sin embargo, la diversidad de la terminología utilizada genera confusión de términos y conceptos. El objetivo de este manuscrito fue proporcionar un listado de los tipos de revisiones de la literatura más frecuentemente utilizados con sus características y algunos ejemplos de ellas. Revisión cualitativa. Se examinaron de forma dirigida las bases de datos PubMed, WoS y Scopus, en búsqueda de términos asociados a tipos de revisiones y síntesis de la literatura científica. Se encontraron 21 tipos de revisión; y 29 variantes y sinonimias asociadas; las que ilustran los procesos de cada una de ellas. Se da una descripción general de las características de cada cual, junto con las fortalezas y debilidades percibidas. No obstante, se verificó que sólo algunos tipos de revisión poseen metodologías propias y explícitas. Este enfoque, proporciona un punto de referencia para quienes realizan o interpretan revisiones en el ámbito sanitario, y sugiere dos tipos de propuestas de clasificación.

SUMMARY: The expansion and consolidation of evidence-based clinical practice has led, among other things, to the need to carry out an increasing variety of types of literature reviews, which allows advancing in knowledge and understanding the breadth of research on a topic of interest. However, the diversity of the terminology used generates confusion of terms and concepts. The aim of this manuscript was to provide a list of the most frequently used review types with their characteristics and some examples. Qualitative review. PubMed, WoS and Scopus databases were examined in a directed way, searching for terms associated with types of reviews and syntheses of the scientific literature. Twenty-one types of review, and 29 variants and associated synonymies were found; those that illustrate the processes of each of them. An overview of the characteristics of each is given, along with perceived strengths and weaknesses. However, it was verified that only some types of review have their own explicit methodologies. This approach, provides a point of reference for those who perform or interpret reviews in the health field and suggests two classification proposals.

Toxina botulínica para prevenção de migrânea: overview de revisões sistemáticas / Botulinum toxin for the prevention of migraine: overview of systematic reviews

Contextualização: A migrânea, também conhecida por enxaqueca, é um distúrbio sensorial relacionado a fatores genéticos, psicológicos e anatômicos, que afeta cerca de 10% dos adultos, trazendo impacto pessoal, social e econômico. Objetivos: Sumarizar as evidências de revisões sistemáticas, referentes à efetividade da toxina botulínica para prevenção de migrânea. Métodos: Trata-se de overview de revisões sistemáticas. Procedeu-se à busca em três bases eletrônicas de dados: Cochrane - Central de Registros de Ensaios Clínicos ­ CENTRAL (2023), PubMed (1966-2023) e EMBASE (1974-2023), sendo utilizados os descritores MeSH "Migraine disorders" e "Botulinum toxins". Todas as revisões sistemáticas de ensaios clínicos randomizados (ECRs) em humanos foram incluídas. O desfecho primário de análise foi a melhora clínica. Resultados: Foram recuperadas 21 revisões sistemáticas e, diante dos critérios de inclusão, 4 foram incluídas, totalizando 94 ECRs (n = 16.104 participantes). Os estudos sugerem que a toxina botulínica pode ser benéfica na redução do número de crises, intensidade de dor e melhora na qualidade de vida dos pacientes. Entretanto, a evidência é limitada. Discussão: Embora os estudos incluídos tragam benefícios favoráveis à toxina botulínica para prevenção da migrânea, a evidência é de baixa qualidade, diante da heterogeneidade, fragilidades metodológicas e riscos nas análises desses estudos. Sugere-se a comparação da efetividade da toxina botulínica com outras intervenções disponíveis, objetivando melhor elucidação da questão. Conclusão: Parece haver algum benefício da toxina botulínica para prevenção de crises de migrânea, mas a evidência até o momento é limitada, sendo recomendada a comparação com outras terapêuticas utilizadas para prevenção da migrânea.

Evaluación de conocimientos y competencias en Medicina Basada en Evidencia en internado de Medicina Familiar / Evaluation of knowledge and skills in medicine based on evidence in spanish family medicine Internship

INTRODUCTION: Evidence-Based Medicine (EBM) is a discipline when used judiciously and considering the preferences of patients, means benefits in clinical contexts and in health care management. It provides tools for a correct analysis of the scientific literature, which would improve decision-making by clinicians. It is a competition that has been trained at the Faculty of Medicine of the UCM. However, there are no formal measurements of the impact of these courses on the development of EBM competencies. OBJECTIVE: this study aims to carry out a brief analysis of knowledge and skills in EBM of family medicine students. MATERIAL AND METHOD: we applied an instrument - ACE Tool as a descriptive approximation of the management level in EBM in medicine students, who have previously had formal training. This instrument evaluates the different stages of EBM. RESULTS: the statistical analysis has reported a level of performance that qualifies students with results below what is desirable, classifying them as a "novice" level of performance. There are no statistically significant differences according to gender.

Abordando el cuerpo de evidencia: conceptos fundamentales de los overviews / Approaching the body of evidence: key concepts of overviews

El aumento de la producción de investigación primaria y de las revisiones de la literatura durante las últimas décadas ha hecho necesario el desarrollo de un nuevo diseño metodológico para sintetizar la evidencia: los overviews. Un overview es un diseño de síntesis de evidencia que toma como unidad de análisis a las revisiones sistemáticas, con el objetivo de extraer y analizar los resultados para una pregunta de interés nueva o más amplia, ayudando así a mejorar los procesos de toma de decisiones informadas. El objetivo de este artículo es introducir al lector a este tipo de resúmenes de evidencia, destacando las diferencias con los otros tipos de síntesis de evidencia, los aspectos metodológicos particulares de los overviews, y los desafíos pendientes. Este artículo es el duodécimo de una serie metodológica colaborativa de revisiones narrativas sobre temáticas de bioestadística y epidemiología clínica.

The increasing production of primary research and literature reviews in the last decades has made it necessary to develop a new methodological design to synthesize the evidence: the overviews. An overview is a type of evidence synthesis that uses systematic reviews as the unit of analysis, with the aim of extracting and analyzing the results for a new or broader research question, helping the shared decision-making processes. The aim of this article is to introduce the reader to this type of evidence summaries, highlighting the differences between overviews and other types of synthesis, the unique methodological aspects of overviews, and future challenges. This is the twelfth article from a collaborative methodological series of narrative reviews about biostatistics and clinical epidemiology.
