Antimicrobial activity of selective serotonin reuptake inhibitors in bacteria and fungi: a systematic review / Atividade antimicrobiana de inibidores seletivos de recaptação de serotonina em bactérias e fungos: uma revisão sistemática

Objective: this systematic review aims to compile literature data on the antimicrobial action of Selective Serotonin Reuptake Inhibitors (SSRI). Methods: To this end, the articles in this review were searched in the PubMed database between the years 2010 to 2020, using terms found in MESH as descriptors. The PRISMA flow diagram was used to analyze the process flow of the research. Later, inclusion and exclusion criteria and eligibility for data extraction and statistical analysis were applied. Results: Thus, of 252 articles found, 13 were used for this systematic review. The period in which there were more publications was in 2016-2017. All articles demonstrated the antimicrobial activity of ISRS, such as sertraline, fluoxetine, and paroxetine, in addition to their synergistic activity with some antifungals and antibacterial. Conclusion: With this, it could be concluded that the repositioning of non-antibiotic drugs that have antimicrobial activity is a promising alternative for the scientific community and, in the future, in clinical practice

Características gerais da doença de Huntington e os desafios com a vida cotidiana: uma revisão da literatura / General characteristics of Huntington's disease and the challenges with everyday life: a literature review

Objetivos: Apresentar as características gerais da DH e os principais desafios encarados no cotidiano pelos portadores. Método: foi realizada uma revisão de literatura na qual foram considerados artigos científicos embasados em banco de dados (PubMed, Scielo, Lilacs e diretório Google Acadêmico), artigos entre anos de 2007 a 2022, publicados em todos os idiomas, e aplicados os seguintes descritores: Huntington's Disease Treatment; Genetics foram incluídos. Resultado: após a inclusão de 21 artigos utilizados, foi observado a significância de elevado índice mundial da DH, que acomete população em geral, porém há probabilidade que seja mais de herança paterna do que materna, devido à formação dos espermatozoides, principalmente quando se manifestam na fase juvenil de forma acelerada. Embora sejam desvendadas alternativas para terapia paliativa medicamentosa, há, também, a terapia física, o que auxilia a possibilidade de evolução na saúde desses indivíduos. Porém, prosseguem as pesquisas relacionadas às condutas melhores na qualidade de vida dessa população. Conclusão: Esta revisão evidencia a importância para doenças neurodegenerativas pouco vistas e comentadas, como a DH, mas que carece de esclarecimentos que auxiliem, com eficácia, tanto na recuperação, como no processo de habilidades da existência desses portadores com DH.

Objectives: to present the general characteristics of HD and the main challenges faced in daily life by patients. Method: a literature review was conducted in which scientific articles were considered based on databases (PubMed, Scielo, Lilacs, and Google Scholar directory), articles between 2007 and 2022, published in all languages, and the following descriptors were applied: Huntington's Disease Treatment; Genetics were included. Result: after the inclusion of 21 articles, it was observed the significance of the high worldwide HD index, which affects the general population, but there is a probability that it is more paternal than maternal inheritance due to sperm formation, especially when they manifest in the juvenile phase in an accelerated manner. Although alternatives for palliative drug therapy are unveiled, there is also physical therapy, which helps the possibility of evolution in the health of these individuals. However, the researches related to the best conducts in the quality of life of this population continue. Conclusion: this review highlights the importance of little-seen and commented neurodegenerative diseases, such as HD, but that lacks clarification that effectively assists, both in recovery and in the process of abilities of the existence of these patients with HD.

Objective: This review determined and reports the prevalence of urinary tract infections and aetiological agents common in most sub-Saharan African countries. Methods: A literature search involved Springer, Hindawi, PubMed, Medcrave, Google Scholar, BioMed, and Elsevier databases to identify the urinary tract infection articles published between 2000 and 2021. Results: Of 111 articles obtained from databases, 22 met the qualities to be included in the study. Overall, the prevalence of UTI was 32.12% with Escherichia coli being the most commonly isolated bacteria accounting for 86.4%. Escherichia coli is found in the GIT thus, the proximity between the anus and urinary system makes the contamination easier. Conclusion: The findings of this study provide useful information for the effective intervention of urinary tract infections. Further, it is advised women wipe from front to back whenever they attend the call of nature and or during bathing.

Objetivo: Relatamos a prevalência de infecções do trato urinário e agentes etiológicos comuns na maioria dos países da África Subsaariana. Metodos: Uma pesquisa bibliográfica envolveu as bases de dados Springer, Hindawi, PubMed, Medcrave, Google Scholar, BioMed e Elsevier para identificar os artigos que abordavam infecção do trato urinário nos países da África Subsaariana, publicados entre 2000 e 2021. Resultados: Dos 111 artigos obtidos nas bases de dados, 22 atenderam aos criterios de inclusao e foram incluídos no estudo . No geral, a prevalência de UTI foi de 32,12%, sendo a Escherichia coli a bactéria mais comumente isolada, representando 86,4%. A Escherichia coli é encontrada no TGI, portanto, a proximidade entre o ânus e o sistema urinário facilita a contaminação. Conclusao: Os achados deste estudo fornecem informações úteis para a intervenção efetiva das infecções do trato urinário. Além disso, é aconselhável que as mulheres busquem fazer sua higiene intima sempre da parte da frente para trás.

Atividade de alcaloides inibidores da acetilcolinesterase no tratamento da doença de Alzheimer: uma revisão sistemática / Activity of Acetylcholinesterase inhibitor Alkaloids in the treatment of Alzheimer's Disease: a systematic review

Objetivo: descrever a atividade de inibição da enzima acetilcolinesterase (AChE), por meio de ativos extraídos de alcaloides naturais. Metodologia: este estudo se configura como uma revisão sistemática da literatura, no período de janeiro de 2015 a setembro de 2021, nas bases de dados PUBMED, LILACS e SCIENCE DIRECT, com os descritores Acetylcholinesterase; Alzheimer; Alkaloids. As informações obtidas foram tabuladas para avaliação dos alcaloides inibidores da acetilcolinesterase. Resultados: de 563 artigos encontrados, 17 foram utilizados. Dois deles relataram a atividade de alcaloides inibidores da AChE por meio de ensaios clínicos, enquanto os demais a realizaram por testes in vitro. De 160 substâncias estudadas, 48 apresentaram atividade anticolinesterásica, as quais foram avaliadas de acordo com a sua concentração inibitória média (IC50). Discussão: a eficiência dos alcaloides como inibidores da AChE, provavelmente está relacionada com sua carga positiva no pH do organismo e sua boa biodisponibilidade, tendo como consequência uma atividade duradoura in vivo, em comparação com os medicamentos sintéticos. Conclusão: no presente estudo, foi possível observar uma grande diversidade de substâncias alcalóidicas antiAChE. Contudo, torna-se necessária a realização de mais ensaios in vivo e in vitro para a constatação efetiva da atividade dessas moléculas.

Objective: describe the activity of the enzyme Acetylcholinesterase (AChE) through natural actives extracted from alkaloids. Methodology: this study is a systematic literature review, from January 2015 to September 2021, in the PUBMED, LILACS, and SCIENCE DIRECT databases, with the descriptors Acetylcholinesterase; Alzheimer's; Alkaloids. The information obtained was tabulated for the evaluation of Acetylcholinesterase inhibitor alkaloids. Results: of 563 articles found, 17 were used. Two of them reported the activity of AChE-inhibiting Alkaloids through clinical trials, while the others performed it through in vitro tests. Of 160 substances studied, 48 showed anticholinesterase activity, which was evaluated according to their mean inhibitory concentration (IC50). Discussion: the efficiency of Alkaloids as AChE inhibitors is probably related to their positive charge on the body's pH and their good bioavailability, resulting in a long-lasting activity in vivo compared to synthetic drugs. Conclusion: in the present study, it was possible to observe a great diversity of antiAChE alkaloid substances. However, it is necessary to carry out more in vivo and in vitro tests to verify the effective activity of these molecules.

Alergia alimentar não IgE mediada: proctocolite induzida por proteínas alimentares ­ Atualização / Non-IgE mediated food allergy: food protein-induced allergic proctocolitis ­ An update

Nas últimas décadas observa-se aumento na prevalência mundial de alergia alimentar, que já acomete aproximadamente 6% das crianças, atribuído à interação entre fatores genéticos, ambientais e alterações na resposta imunológica e pode envolver reações mediadas por IgE, não mediadas e mistas. As formas não IgE mediadas decorrem de reação de hipersensibilidade tardia, mediada por linfócitos T e afetam prioritariamente o trato gastrointestinal, como a Síndrome da enterocolite induzida por proteína alimentar (FPIES), Síndrome da proctocolite alérgica induzida por proteína alimentar (FPIAP), Síndrome da enteropatia induzida por proteína alimentar (FPE) e doença celíaca. As características destas reações podem ser diferenciadas por sua apresentação clínica, gravidade, idade de início e história natural. Entre as reações alérgicas aos alimentos não IgE mediadas, a proctocolite alérgica é a mais frequente. Geralmente ocorre no primeiro ano de vida e apresenta excelente prognóstico. Embora costume ter um curso benigno, traz grande preocupação aos cuidadores por frequentemente cursar com quadro de hematoquezia exigindo diagnóstico diferencial adequado. O conhecimento e manejo da proctocolite alérgica é de suma importância para a prática médica em Alergia e Imunologia. Seu diagnóstico é baseado na história clínica seguindo-se dieta de exclusão, especialmente do leite de vaca, com subsequente provocação oral, que geralmente pode ser realizada no domicílio. O diagnóstico preciso é importante, para se evitar dietas de exclusão desnecessárias. Nesta revisão foram utilizados artigos publicados nos últimos anos, com busca realizada através da base PubMed envolvendo revisões, diagnóstico e tratamento de alergias não IgE mediadas, com foco em proctocolite alérgica.

An increase in the worldwide prevalence of food allergies has been observed in the past decades, currently affecting 6% of children. This increase has been associated with the interaction between genetic, environmental, and immune response factors and can be observed in IgE, non-IgE, and mixed mediated reactions. Non-IgE mediated food allergies result from delayed-type hypersensitivity and mostly affect the gastrointestinal tract, such as food protein-induced enterocolitis syndrome (FPIES), food protein-induced allergic proctocolitis (FPIAP), food protein-induced enteropathy (FPE), and celiac disease. These reactions can be differentiated by their clinical presentation, severity, age at onset, and natural history. Among non-IgE-mediated allergic reactions to food, allergic proctocolitis is the most frequent. It usually develops in the first year of life and has excellent prognosis. Although it has a benign course, allergic proctocolitis is challenging for health care professionals because it often presents with hematochezia, requiring an accurate differential diagnosis. Knowledge and management of allergic proctocolitis is of paramount importance for medical practice in allergy and immunology. Its diagnosis is based on clinical history followed by elimination diet, especially cow's milk, with subsequent oral food challenge, which may usually be performed at home. Accurate diagnosis is important to avoid unnecessary elimination diets. For this review, PubMed database was searched for recently published literature reviews and studies on the diagnosis and treatment of non- IgE mediated allergies, with a focus on allergic proctocolitis.

Imunologia da tuberculose: uma revisão narrativa da literatura / Tuberculosis immunology: a narrative literature review

A resposta imune desenvolvida pelo hospedeiro contra o Mycobacterium tuberculosis é considerada de natureza complexa e multifacetada. Esta interação bacilo-hospedeiro resulta, na maioria das vezes, em uma infecção latente assintomática, podendo ou não evoluir para a forma ativa da tuberculose (TB). O presente estudo objetivou atualizar e sumarizar o conhecimento científico acerca dos mecanismos imunológicos associados à infecção e sua progressão para a TB ativa. Trata-se de uma revisão narrativa, realizada a partir do levantamento bibliográfico de artigos científicos indexados nas bases de dados PubMed/MEDLINE e SciELO, nos últimos 20 anos. Nas últimas décadas, a caracterização de linfócitos Tγδ, MAIT, iNKT e outra células T CD1 restritas proporcionaram um maior entendimento do papel da imunidade inata na infecção pelo bacilo. A migração de linfócitos T CD4+ produtores de IFN-g, TNF-α e de outras moléculas solúveis, promove o recrutamento e formação do granuloma, estrutura que beneficia tanto o hospedeiro quanto o bacilo. Eventualmente, um desequilíbrio nesta complexa rede de interação, resulta em uma resposta inflamatória exacerbada que contribui para o desenvolvimento de um granuloma necrótico. Por fim, a exaustão da resposta imune local frente à contínua exposição ao bacilo, associada ao perfil anti-inflamatório dos linfócitos Th2 e linfócitos Treg, favorecem a inativação funcional e, consequentemente, o desenvolvimento da doença ativa. A resposta imunológica é crucial para o desenvolvimento da infecção por M. tuberculosis. Portanto, estudos que possibilitem uma maior compreensão sobre a interação bacilohospedeiro podem viabilizar o desenvolvimento de novos métodos diagnósticos, estratégias terapêuticas e, sobretudo, avanços no desenvolvimento de imunobiológicos.

The immune response developed by the host against Mycobacterium tuberculosis is considered a complex and multifaceted nature. This host-bacillus interaction, which in most cases results in an asymptomatic latent infection that may or may not evolve to the development of active pulmonary tuberculosis (TB). The present study aimed to update and summarize the current scientific knowledge regarding the immunological mechanisms associated with infection and the development of active disease. This is a narrative review, based on scientific articles indexed in the PubMed/ MEDLINE and SciELO databases over the last 20 years. In recent decades, the characterization of Tγδ lymphocytes, MAIT, iNKT and CD1-restricted T cells has provided a better understanding of the role of innate immunity in bacilli infection. The migration of T CD4+ lymphocytes that produce IFN-γ, TNF-α and other soluble molecules, promotes the recruitment and formation of the granuloma, a structure that benefits both the host and the bacillus. Eventually, an imbalance in this complex interaction network results in an exacerbated inflammatory response that contributes to the development of a necrotic granuloma. Finally, exhaustion of the local immune response due to continuous exposure to the bacillus, associated with the anti-inflammatory profile of Th2 lymphocytes and Treg lymphocytes, favor functional inactivation and, consequently, the development of active disease. The immune response is crucial for the development of M. tuberculosis infection. Therefore, studies that enable a greater understanding of the hostbacillus interaction may enable the development of new diagnostic methods, therapeutic strategies and, above all, advances in the development of immunobiologicals.

A pandemia de COVID-19 e o seu impacto à saúde planetária / The COVID-19 pandemic and its impact on planetary health

A pandemia de COVID-19 deu ao mundo uma imagem clara do que é uma crise multidimensional em escala planetária, revelando o papel central que ocupa o setor de saúde e as profundas desigualdades no acesso aos cuidados em saúde que existem entre os diferentes países, e dentro de cada um deles. Melhorar os efeitos ambientais do setor e reduzir as emissões de gases de efeito estufa pode não apenas melhorar a saúde de todos, mas também reduzir os custos com os cuidados em saúde. O setor de saúde de cada país libera direta e indiretamente gases de efeito estufa ao fornecer seus serviços e ao comprar produtos, serviços e tecnologias em uma cadeia de fornecimento de carbono intensivo. Educar os profissionais de saúde mais profundamente sobre os efeitos das mudanças climáticas pode levar a práticas clínicas mais sustentáveis, melhorando os resultados para os pacientes e fornecendo um impulso substancial para aumentar os esforços para reduzir as emissões de carbono. O setor da saúde deve assumir a responsabilidade por sua pegada climática respondendo à crescente emergência climática, não apenas prestando assistência aos doentes, feridos ou moribundos como resultado da crise climática e suas causas, mas também fazendo a prevenção primária e reduzindo drasticamente suas próprias emissões.

The COVID-19 pandemic has painted a clear picture of what a multidimensional planetary crisis is, revealing the central role played by the health sector and the deep inequalities in access to health care that exist between and within each country. Decreasing the environmental effects of the health sector and reducing greenhouse gas emission may not only improve people's health, but also reduce health care costs. The health care sectors around the world directly and indirectly release greenhouse gases by providing their services and purchasing products, services, and technologies within a carbon-intensive supply chain. Further educating health care professionals about the effects of climate change may lead to more sustainable clinical practices, improving patient outcomes and providing substantial impetus to increased efforts to reduce carbon emission. The health sector must take responsibility for its climate footprint by responding to the growing climate emergency not only by assisting the sick, injured, or dying from the climate crisis, but also by doing primary prevention and drastically reducing its own carbon emission.

El desafío para el desarrollo del sistema nervioso central en la reproducción humana asociada con la diabetes / The challenge for the development of the central nervous system in human reproduction associated with diabetes

Introducción: Los hijos de madres con diabetes presentan una mayor incidencia de trastornos del neurodesarrollo como autismo, actividad cognitiva baja, déficit de atención, esquizofrenia y otras enfermedades del espectro autista. Objetivo: Explicar los mecanismos moleculares que subyacen en la aparición de los trastornos del neurodesarrollo en hijos de gestantes con diabetes. Métodos: Se llevó a cabo una revisión de la literatura que aparece en las bases de datos electrónicas Google, MEDLINE/PubMed y SciELO. Se revisaron artículos publicados entre los años 2000 y 2020. Las palabras clave utilizadas fueron: hiperglucemia, neurodesarrollo, malformaciones congénitas y epigenética. Resultados: Se pone de manifiesto el alto riesgo que representa la hiperglucemia durante el desarrollo intrauterino. El riesgo relativo que tienen los hijos de madres con diabetes pregestacional de presentar malformaciones del sistema nerviosos central es 15,5 veces mayor que en gestantes sin diabetes. El hipocampo es especialmente sensible a cambios en los niveles de glucosa. La diabetes materna puede dejar una impronta negativa para la capacidad de procesar información, adquirir habilidades y poseer un comportamiento social adecuado en la descendencia. Conclusiones: Las alteraciones en el metabolismo condicionadas por la hiperglucemia, el estrés oxidativo, la inflamación de bajo grado y las modificaciones epigenéticas crean un fatal engranaje que sustenta el desarrollo anómalo en hijos de gestantes con diabetes(AU)

Introduction: Children, whose mothers suffer from diabetes, have higher incidence of neurodevelopmental disorders such as autism, low cognitive activity, attention deficit, schizophrenia and other autism spectrum diseases. Objective: To explain the molecular mechanisms that underlie the appearance of neurodevelopmental disorders in children of pregnant women with diabetes. Methods: A review of the literature that appears in Google, MEDLINE/PubMed and SciELO electronic databases, was carried out. Articles published from 2000 to 2020 were reviewed. The keywords used were hyperglycemia, neurodevelopment, congenital malformations, and epigenetics. Results: The high risk that hyperglycemia represents during intrauterine development is highlighted. The relative risk that children of mothers with pregestational diabetes have of presenting malformations of the central nervous system is 15.5 times higher than in pregnant women without diabetes. The hippocampus is especially sensitive to changes in glucose levels. Maternal diabetes can leave negative print on the ability to process information, acquire skills and have appropriate social behavior in their children. Conclusions: Alterations in metabolism conditioned by hyperglycemia, oxidative stress, low-grade inflammation and epigenetic modifications create a fatal mechanism that supports abnormal development in children of pregnant women with diabetes(AU)

Introdução dos alimentos no primeiro ano de vida e prevenção da alergia alimentar: quais as evidências? / Introduction of food in the first year of life and food allergy prevention: what is the evidence?

Objetivo: A incidência das doenças alérgicas cresceu nas últimas décadas. Na tentativa de conter o aumento da alergia alimentar (AA) ao longo dos anos, estratégias de prevenção vêm sendo implementadas. Para promover um melhor entendimento dos dilemas que permeiam a introdução alimentar no primeiro ano de vida, esse artigo trata de uma revisão bibliográfica narrativa sobre a introdução dos alimentos complementares no primeiro ano de vida e possíveis associações com a prevenção primária da alergia alimentar. Fonte dos dados: Publicações relevantes foram pesquisadas nas bases de dados Cochrane Library, MEDLINE, PubMed, Guidelines International Network, National Guidelines Clearinghouse e revisadas recomendações do guia e do consenso nacional de alergia alimentar. Resultados: Estudos observacionais diversos e ensaios clínicos randomizados estão disponíveis, bem como recomendações publicadas por organizações científicas; no entanto, de qualidade variável. Foram consideradas as recomendações de diretrizes de prática clínica classificadas como de alta qualidade e publicações recentes ainda não categorizadas de forma sistemática em sua qualidade, mas internacionalmente reconhecidas como relevantes para a atenção primária. Conclusão: Até o momento, não há evidências consistentes de que a introdução precoce, antes dos 6 meses, dos alimentos alergênicos, contribua para a prevenção de alergia a alimentos na população geral.

Objective: The incidence of allergic diseases has increased in recent decades. In an attempt to contain the increase in food allergy (AA) over the years, prevention strategies have been implemented. To promote a better understanding of the dilemmas that permeate the introduction of food in the first year of life, this article deals with a narrative literature review on the introduction of complementary foods in the first year of life and possible associations with the primary prevention of food allergy. Data source: Relevant publications were searched in the Cochrane Library, MEDLINE, PubMed, Guidelines International Network, National Guidelines Clearinghouse, and revised recommendations from the national food allergy guide and consensus. Results: Several observational studies and randomized controlled trials are available, as well as recommendations. published by scientific organizations; however, of variable quality. Recommendations from clinical practice guidelines classified as high quality and recent publications not yet systematically categorized in their quality, but internationally recognized as relevant to primary care, were considered. Conclusion: To date, there is no consistent evidence that the early introduction, before 6 months, of allergenic foods contributes to the prevention of food allergy in the general population.

Infecções graves por SARS-CoV-2 com uso de tocilizumabe / Severe infections by SARS-CoV-2 with the use of tocilizumab

O SARS-CoV-2 é causador da doença infecciosa COVID-19. A infecção estimula o sistema imunológico a produzir citocinas próinflamatórias. A principal citocina envolvida é a IL-6, e está ligada à gravidade da doença. Devido à associação dos altos níveis de IL-6 com a mortalidade na COVID-19, investiga-se sobre o uso de tocilizumabe (TCZ), um anticorpo monoclonal humanizado antirreceptor de IL-6 humana. O objetivo desta revisão sistemática é avaliar a eficácia do uso do TCZ em pacientes com COVID-19 grave. As buscas foram feitas através das bases de dados Science Direct e PubMed em setembro de 2021. Foram incluídos os ensaios clínicos randomizados com pacientes em um único estágio de COVID-19, casos graves e sem restrição de idade, os quais receberam o TCZ como medicação de intervenção combinado a tratamentos protocolados por cada hospital e associado a corticosteroides. A análise desses estudos demonstrou resultados significantes sobre o uso de TCZ em casos severos de COVID-19. O uso de TCZ associado a glicocorticoides levou a uma redução no índice de mortalidade e de submissão a ventilações mecânicas e a uma melhora expressiva em relação à escala "WHO-endorsed 7-point ordinal scale". Entretanto, não houve melhora relevante quanto ao uso do TCZ de maneira isolada.

SARS-CoV-2 causes the COVID-19 infectious disease that affects the respiratory tract. From the beginning of the infection, the immune system starts to produce pro-inflammatory cytokines and chemokines. The main cytokine involved is IL-6 and is linked to the severity and prognosis of the disease, as it provokes a storm of cytokines and severe inflammatory responses. Due to the association of high levels of IL-6 with severity and mortality in COVID-19, the use of Tocilizumab (TCZ), a humanized anti-human IL-6 receptor monoclonal antibody, which binds to IL receptors, is being investigated. -6 and blocks intracellular signaling reducing cytokine storm and hyperinflammatory state. The aim of this review is to assess the effectiveness of using TCZ in the treatment of patients with severe COVID-19. Searches were performed using the Science Direct and PubMed databases in May 2021. Randomized clinical trials with patients in a single stage of COVID­19, severe cases and without age restriction, who received TCZ as medication for treatment, were included. Intervention was combined with treatments protocoled by each hospital and associated with corticosteroids. The analysis of these studies showed significant results regarding the use of TCZ in severe cases of COVID-19. The use of TCZ associated with glucocorticoids led to a reduction in the rate of mortality and compliance with mechanical ventilation and a significant improvement in relation to the "WHO-endorsed 7-point ordinal scale". However, there was no evidence of relevant improvement when using TCZ alone.

Probiotics in Crohn's disease remission: a systematic review

Crohn's disease (CD) is an inflammatory condition that can affect the entire gastrointestinal tract due to an exacerbated and inadequate immune system response. Objective. This study aimed to conduct a systematic review, through clinical trials, about the use of probiotics in humans with CD. Materials and methods. Research was carried out in the PubMed, Scopus and Science Direct databases using the keywords "Crohn's disease" and "probiotics". We conducted the review by searching clinical trials published from 2000 to December 2019. Results. Of 2,164 articles found, only nine were considered eligible for this review. The studies investigated patients with CD at different stages of the pathology, and in three studies the potential effect of probiotics in the active phase was observed; in two, in the remission phase; and in four, after intestinal surgery. The sample size of the studies ranged from 11 to 165 individuals and the age of the participants between 5 and 71 years. Gram-positive bacteria were used in six clinical interventions and in two studies yeasts were used. As for the significant results obtained with the treatment with probiotics, in one study there was beneficial clinical effects in patients and, in another, there was an improvement in intestinal permeability. Conclusion. Currently, it is not possible to establish a recommendation for probiotic therapy to control CD due to the few clinical trials with significant results. There is a need for more research on clinical intervention with probiotics in CD to clarify the action, define doses and time of use(AU)

La enfermedad de Crohn (EC) es una afección inflamatoria que puede afectar todo el tracto gastrointestinal debido a una respuesta del sistema inmunitario exacerbada e inadecuada. Objetivo. Realizar una revisión sistemática, a través de ensayos clínicos, sobre el uso de probióticos en humanos con EC. Materiales y métodos. La investigación se realizó en las bases de datos PubMed, Scopus y Science Direct utilizando las palabras clave "enfermedad de Crohn" y "probióticos". La revisión se hizo en ensayos clínicos publicados desde 2000 hasta diciembre 2019. Resultados. De 2164 artículos encontrados, solo nueve fueron considerados elegibles. Los estudios investigaron pacientes con EC en diferentes etapas de la patología, y en tres estudios se observó el efecto potencial de los probióticos en la fase activa; en dos, en remisión; y en cuatro, tras cirugía intestinal. El tamaño de la muestra fue entre 11 y 165 individuos y la edad entre 5 y 71 años. Se utilizaron bacterias grampositivas en seis intervenciones clínicas y en dos estudios se utilizaron levaduras. En cuanto a los resultados significativos obtenidos con el tratamiento con probióticos, en un estudio hubo efectos clínicos beneficiosos en los pacientes y, en otro, hubo una mejora en la permeabilidad intestinal. Conclusión. Actualmente, no es posible establecer una recomendación de terapia con probióticos para el control de la EC debido a los pocos ensayos clínicos con resultados significativos. Existe la necesidad de más investigación sobre la intervención clínica con probióticos en EC para aclarar la acción, definir dosis y tiempo de uso(AU)

Scientific production and most researched diseases in the Biological Sciences postgraduate programs in Brazil / Produção científica e doenças mais pesquisadas nos programas de pós-graduação em Ciências Biológicas no Brasil

This macro-level scientometrics study aimed to analyze the similarities and differences in the scientific communication patterns of the Brazilian postgraduate programs (BPPs) belonging to the Biological Sciences II field (BS2), as defined by Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). Also, it was identified the most researched diseases and it was discussed their relationship with the needs of Brazilian public health considering the burden of disease (Disability-Adjusted Life Year - DALY, Brazil) estimated by the World Health Organization (WHO). Thus, the scientific production of the BS2's sub-areas Biophysics, Biochemistry, Pharmacology, Physiology, and Morphology was evaluated from 2013 to 2016, through considering the citation impact, Impact Factor (Journal Citation Reports), and scientific collaboration. Data collected included formal information provided to CAPES by all BPPs through the Plataforma Sucupira as well as metadata from Web of Science documents. In addition, were employed the standardized Medical Subject Headings (PubMed) for the analysis of researched diseases. We concluded that the patterns of scientific communication in Biophysics, Biochemistry, Pharmacology, Physiology, and Morphology were predominantly different. Thus, there is a need to consider specificities among the five sub-areas in the evaluation process performed by CAPES. Different approaches are revealed by identifying the most frequently researched diseases and explaining the contributions of each sub-area for Brazilian public health.

Este estudo cientométrico de nível macro teve como objetivo analisar as semelhanças e as diferenças nos padrões de comunicação científica dos programas de pós-graduação brasileiros (PPGs) da área de Ciências Biológicas II, avaliados pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). Além disso, foram identificadas as doenças mais pesquisadas e foi discutido sua relação com as necessidades de saúde pública brasileira, considerando a carga de doenças (Disability-Adjusted Life Year - DALY, Brasil) estimada pela Organização Mundial da Saúde (OMS). Assim, a produção científica das subáreas Biofísica, Bioquímica, Farmacologia, Fisiologia e Morfologia da área de Ciências Biológicas II foi avaliada de 2013 a 2016, considerando o impacto de citações, o Fator de Impacto (Journal Citation Reports) e a colaboração científica. Os dados coletados incluíram informações declaradas à CAPES por todos os PPGs por meio da Plataforma Sucupira, bem como metadados de documentos da Web of Science. Além disso, foram utilizados os cabeçalhos de Medical Subject Headings (PubMed) para a análise das doenças pesquisadas. Concluímos que os padrões de comunicação científica entre as subáreas Biofísica, Bioquímica, Farmacologia, Fisiologia e Morfologia foram predominantemente diferentes. Assim, é necessário considerar as especificidades entre as cinco subáreas no processo de avaliação realizado pela CAPES. Diferentes abordagens são reveladas a partir da identificação das doenças mais pesquisadas e da explicação das contribuições de cada subárea para a saúde pública brasileira.

Analysis on influencing factors of acupuncture curative effect based on experts' experience / 中国针灸

To explore the influencing factors of acupuncture curative effect in literature of experts' experience. The journal literature of experts' experience was retrieved from China National Knowledge Infrastructure (CNKI) and PubMed, starting from inception to September 4, 2020, and the influencing factors of acupuncture curative effect were extracted and analyzed. A total of 499 articles were included, involving 495 articles in Chinese and 4 articles in English. The influencing factors of acupuncture curative effect mainly include five aspects: diagnostic method, acupoint selection of acupuncture, acupuncture manipulation, regulating mind of acupuncture and acupuncture time, and provide reference for acupuncture protocol design in clinical trials.

Factors associated with positive results in English literature of acupuncture for chronic pain / 中国针灸

OBJECTIVE@#To analyze the main factors affecting the positive results of acupuncture for chronic pain in English literature of randomized controlled trial (RCT), in order to provide reference for the design of acupuncture clinical research.@*METHODS@#The RCTs of acupuncture for chronic pain published before March 26, 2020 were searched in PubMed, EMbase and Cochrane Library by computer. A total of 21 factors were analyzed by single-factor analysis, and the factors with statistically significant difference were selected for multivariate Logistic regression analysis.@*RESULTS@#A total of 69 RCTs were included, including 47 RCTs (68.12%) with positive results and 22 RCTs (31.88%) with non-positive results. The multivariate Logistic regression analysis was performed with the three screened factors (publication year, treatment frequency and intervention form) selected by single-factor analysis, and the results showed that the positive results were related to the frequency of acupuncture treatment. The positive rate of RCT with frequency≥2 times a week was 3.24 times of that with frequency<2 times a week (OR=3.24, 95%CI =[1.07,9.83], P<0.05).@*CONCLUSION@#Acupuncture frequency may be the main factor affecting the positive results of RCT in English literature of acupuncture for chronic pain. More researches are needed in the future to explore the influence of acupuncture frequency on the curative effect.

Overview of systematic reviews of acupuncture clinical research published in international journals / 中国针灸

The systematic reviews (SRs) of acupuncture published before December 31 of 2020 in PubMed, Cochrane and EMbase databases were searched, and the publication overview of international acupuncture SRs were analyzed. As a result, a total of 717 SRs were included, and the overall number of published SRs showed a fluctuating upward trend. A total of 15 categories of diseases were involved, of which 113 SRs suggested that acupuncture was effective, and 12 SRs did not support acupuncture, and the remaining SRs showed uncertain conclusions. It is suggested that the standard of evidence-based medicine should be adopted to standardize the design of acupuncture trial and improve the level of clinical research; SRs should include high-quality literature that met the standards according to the principles and methods of PRISMA, so as to provide reliable clinical evidence for acupuncture.
