Abstract Quilombolas are ethnic-racial groups, of black ancestry, and had their territories consolidated in Brazil in regions with difficult access and far from large centers. The objective of this study is to know the therapeutic itinerary (IT) adopted by quilombola women in traditional communities located in the North of the state of Minas Gerais. This is a qualitative study with the theoretical model using the Arthur Kleinman health care system. The study scenario was 23 quilombola communities in northern Minas Gerais. Forty quilombola women aged between 25 and 89 years were interviewed. Data analysis was performed following the IT. Units of analysis emerged that were grouped into three categories: quilombola women and the meaning of health and care; the professional care system in quilombola communities; and route of care in situations experienced by women. The therapeutic itinerary of the communities is mainly related to the actions of popular medicine. It was also possible to observe that there are weaknesses in relation to health care due to factors such as difficulty of access to institutionalized services.

Resumo Os quilombolas são grupos étnico-raciais de ancestralidade negra e tiveram seus territórios consolidados no Brasil em regiões com acesso difícil e distante dos grandes centros. O objetivo desse estudo é conhecer o itinerário terapêutico (IT) adotado por mulheres quilombolas em comunidades tradicionais localizadas no norte do estado de Minas Gerais. Trata-se de um estudo com abordagem qualitativa com o modelo teórico utilizando o sistema de cuidados à saúde de Arthur Kleinman. O estudo se deu em 23 comunidades quilombolas do norte de Minas Gerais. Foram entrevistadas 40 mulheres quilombolas, com idades entre 25 e 89 anos. A análise dos dados foi realizada seguindo os IT. Emergiram unidades de análise que foram agrupadas em três categorias: as mulheres quilombolas e o significado da saúde e do cuidado; o sistema de cuidado profissional nas comunidades quilombolas; e itinerário de cuidados nas situações vivenciadas pelas mulheres. O itinerário terapêutico das comunidades se mostra relacionado principalmente às ações de medicina popular. Foi possível observar ainda que existem fragilidades em relação à atenção à saúde devido a fatores como dificuldade de acesso aos serviços institucionalizados.

Abstract Background: Different management styles can modify families’ functioning, favoring or compromising the care delivered to chronic childhood conditions. Objective: To analyze primary caregivers’ perspectives on family management of chronic childhood conditions. Methodology: This qualitative study is based on the Family Management Style Framework (FMSF). Thirty-eight (38) interviews were conducted with 38 caregivers of chronically ill children attending a health institution in southeastern Brazil. The data were submitted to deductive thematic analysis. Results: Having a child with chronic illness was described as challenging and causing suffering, requiring families to reorganize their family routines to meet the chronically ill child’s needs. The “perceived consequences” revealed families’ perspectives and fears about the future and their recognition of the results of the “management behaviors” adopted. The family management styles identified were: “thriving,” “accommodating,” “struggling,” “floundering,” and “enduring.” Conclusion: The primary caregiver’s ability to manage the chronically ill child’s needs depends on their access to professional, care, and intra-family resources.

Resumo Enquadramento: Diferentes estilos de gestão podem modificar o funcionamento familiar, favorecendo ou comprometendo o cuidado das condições crónicas na infância. Objetivo: Analisar, na perspetiva do cuidador principal, a gestão familiar em situações que envolvem condições crónicas na infância. Metodologia: Estudo qualitativo, orientado pelo Family Management Style Framework, realizado a partir de entrevistas com 38 cuidadores de crianças com condições crónicas, atendidas numa instituição de saúde do sudeste brasileiro. Os dados foram submetidos a análise temática do tipo dedutiva. Resultados: A situação da condição crónica é definida como difícil e causadora de sofrimento, exigindo uma reorganização da rotina familiar para atender às exigências da criança. As consequências percebidas expressam perspetivas e receios sobre o futuro e reconhecimento dos resultados dos comportamentos de gestão adotados. foram identificados estilos de gestão como a família ajustada, em adaptação, em luta, em conflito e em espera. Conclusão: A capacidade do cuidador principal em gerenciar as necessidades da criança com condição crónica, de forma positiva, depende do acesso aos recursos profissionais, assistenciais e intrafamiliares.

Abstract Background Computerized cognitive training programs may have benefited the self-assessment of memory, quality of life, and mood among older adults during the coronavirus disease 2019 (COVID-19) pandemic. Objective To determine the subjective impacts of computerized cognitive training on mood, frequency of forgetfulness, memory complaints, and quality of life in the elderly using an online platform. Methods In total, 66 elderly participants of USP 60 +, a program for the elderly offered by Universidade de São Paulo, who voluntarily enrolled in the study were selected and randomized with an allocation ratio of 1:1 into 2 groups: the training group (n = 33) and the control group (n = 33). After signing the free and informed consent form, they answered a protocol which included a sociodemographic questionnaire, the Memory Complaints Questionnaire (MAC-Q), the McNair and Kahn’s Frequency of Forgetfulness Scale, the Geriatric Depression Scale (GDS-15), the Geriatric Anxiety Inventory (GAI), and the Control, Autonomy, Self-Realization, and Pleasure (CASP-19) questionnaire. The training cognitive game platform aimed to stimulate various cognitive aspects, including memory, attention, language, executive functions (reasoning, logical thinking), and visual and spatial skills. Results The participants of the training group showed a reduction in the MAC-Q, MacNair and Kahn, and GAI scores in the pre- and posttest comparison. Significant differences were identified between the groups regarding the total scores of the MAC-Q in the post-test, which was also evidenced by the logistic regression. Conclusion Participation in a computerized cognitive intervention promoted reductions in memory complaints, frequency of forgetfulness, and anxiety symptoms, in addition to improving self-reported quality of life.

Resumo Antecedentes Programas informatizados de treinamento cognitivo podem ter beneficiado a autoavaliação da memória, a qualidade de vida e o humor entre os idosos durante a pandemia de doença do coronavírus 2019 (coronavirus disease 2019, COVID-19, em inglês). Objetivo Determinar os impactos subjetivos do treinamento cognitivo computadorizado no humor, na frequência de esquecimento, nas queixas de memória, e na qualidade de vida em idosos utilizando uma plataforma online. Métodos Ao todo, 66 idosos participantes do programa USP 60 +, oferecido à terceira idade pela Universidade de São Paulo, e inscritos voluntariamente no estudo, foram selecionados e randomizados em uma razão de 1:1 em 2 grupos: grupo treinamento (n = 33) e grupo controle (n = 33). Após assinarem o termo de consentimento livre e esclarecido, os participantes responderam a um protocolo que incluía um questionário sociodemográfico, o Questionário de Queixas de Memória (Memory Complaints Questionnaire, MAC-Q), A Escala de Frequência de Esquecimento de McNair e Kahn, a Escala de Depressão Geriátrica (Geriatric Depression Scale, GDS-15), o Inventário de Ansiedade Geriátrica (Geriatric Anxiety Inventory, GAI), e –o questionário de Controle, Autonomia, Autorrealização e Prazer (Control, Autonomy, Self-Realization, and Pleasure, CASP-19).

Abstract This study evaluated the antimicrobial capacity of BlueM® mouthwash against the bacterium Streptococcus mutans and its influence on gbpA gene expression as well as its cytotoxic effect on fibroblast cells. BlueM® showed antimicrobial activity, with MIC and MBC values of 0.005% and 0.01%, respectively. The MBIC was 6.25% for S. mutans. CFU count and confocal microscopy revealed significant effect of BlueM® on S. mutans biofilm pre-formed on dentin surfaces. Interestingly, the analysis of gbpA gene expression indicated a decrease in gene expression after 15 min of treatment with BlueM® at a concentration of 25%. Moreover, BlueM® exhibited low levels of cytotoxicity. In conclusion, our results showed the antimicrobial effectiveness of BlueM® against S. mutans, its ability to modulate the expression of the gbpA gene and its low cytotoxicity. This study supports the therapeutic potential of BlueM® as an alternative agent for the control of oral biofilm.

Resumo Este estudo avaliou a capacidade antimicrobiana do enxaguatório BlueM® contra a bactéria Streptococcus mutans e sua influência na expressão do gene gbpA, bem como seu efeito citotóxico em células de fibroblastos. BlueM® apresentou atividade antimicrobiana, com valores de CIM e CBM de 0,005% e 0,01%, respectivamente. O MBIC foi de 6,25% para S. mutans. A contagem de UFC e a microscopia confocal revelaram efeito significativo do BlueM® no biofilme de S. mutans pré-formado nas superfícies de dentinas. Curiosamente, a análise da expressão do gene gbpA, indicou uma diminuição na expressão do gene após 15 min de tratamento com BlueM® na concentração de 25%. Além disso, BlueM® exibiu baixos níveis de citotoxicidade. Em conclusão, nossos resultados mostraram a eficácia antimicrobiana do BlueM® contra S. mutans, sua capacidade de modular a expressão do gene gbpA e sua baixa citotoxicidade. Este estudo apoia o potencial terapêutico do BlueM® como agente alternativo para o controle do biofilme oral.

Abstract Projects on river basin integration are keen social-economical drivers in dry regions like the Brazilian semiarid, however, there are concerning ecological impacts implied in those projects. In a long-term analysis, ichthyofauna colonization and spread through the East Axis of the São Francisco River Integration Project (SFIP) was monitored to assess possible impacts on the receiving Paraíba River basin. The fish were collected semiannually (2012 to 2021) from 19 sites in the São Francisco (SF) and Paraíba (PB) basins. A total of 69 fish species were recorded, with distinct fish assemblages between SF (n = 50), PB (n = 35), and the SFIP artificial reservoirs (n = 25). The SFIP reservoirs were colonized by species from the donor basin (SF). In a pioneer finding, Anchoviella vaillanti was recorded for the first time in the receiving basin and it is in the process of establishment. The two SF species that reached PB through the SFIP canals (A. vaillanti and Moenkhausia costae) may be using their year-round reproduction and wide diet to successful spread and colonize the new environment. Since we detected species with potential to reach the receiving basin and became invasives, the implementation of barriers to contain their spread are recommended.

Resumo Projetos de integração de bacias hidrográficas são socialmente importantes em regiões como o semiárido brasileiro, porém há impactos ecológicos preocupantes implícitos nesses grandes projetos de infraestrutura. A colonização e dispersão da ictiofauna pelo Eixo Leste do Projeto de Integração do Rio São Francisco (PISF) foi monitorada para avaliar possíveis impactos na bacia receptora do rio Paraíba do Norte. Os peixes foram coletados semestralmente (2012 a 2021) em 19 locais das bacias do São Francisco (SF) e Paraíba (PB). Foram registradas 69 espécies de peixes, sendo 50 nos pontos do SF, 25 nos reservatórios artificiais ao longo do PISF e 35 nos pontos do PB. As assembleias de peixes das bacias do SF, PB e dos reservatórios do PISF foram significativamente distintas. Os reservatórios do PISF foram colonizados por espécies provenientes da bacia doadora (SF). Anchoviella vaillanti foi registrada pela primeira vez na bacia receptora do PB e está em processo de estabelecimento. As duas espécies do SF que chegaram ao PB pelos canais do PISF (A. vaillanti e Moenkhausia costae) apresentaram dieta e estratégias reprodutivas que permitem o sucesso na disseminação e colonização. Uma vez que foram detectadas espécies com potencial de atingir a bacia receptora, recomenda-se o monitoramento e manejo contínuos.

ABSTRACT BACKGROUND: Social distancing has led to lifestyle changes among older adults during the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVES: This study aimed to estimate the prevalence risk of sarcopenia (RS) and investigate its associated factors during the COVID-19 pandemic in older Brazilian adults. DESIGN AND SETTING: Cross-sectional observational analysis of baseline data as part of the Remobilize Study. METHODS: Participants in the study were older adults (≥ 60 years), excluding those who were bedridden or institutionalized. The data collected consisted of answers about the RS (SARC-F), functional status, walking, sedentary behavior (SB), pain, comorbidity, and life space mobility. RESULTS: A total of 1,482 older adults (70 ± 8.14 years, 74% women) participated in the study, and an RS prevalence of 17.1% was found. (95% confidence interval [CI] 15.25–19.15%). The adjusted multivariate model showed a significant association between RS and functional limitation (odds ratio [OR]: 19.05; CI 13.00–28.32), comorbidity (OR: 5.11; CI 3.44–7.81), pain (OR: 4.56; CI 3.33–6.28), total walking (OR: 0.99; CI 0.99–1.00), SB of 8–10 hours (OR: 1.85; CI 1.15–2.93), and SB of > 10 hours (OR: 3.93; CI 2.48–6.22). RS was associated with mobility during the pandemic (OR: 0.97; CI 0.96–0.98). P < 0.05. CONCLUSIONS: During the pandemic, the prevalence of RS in older Brazilians was estimated at 17.1%. Moderate to severe functional limitation, comorbidities, presence of pain, walking, longer SB period, and reduced life space mobility significantly contributed to RS in older adults during the pandemic.

ABSTRACT Objective To investigate the expression of human papillomavirus (HPV), p16, p53, and p63 in non-schistosomiasis-related squamous cell carcinoma of the bladder and to develop an accurate and automated tool to predict histological classification based on clinicopathological features. Methods Twenty-eight patients with primary bladder pure squamous cell carcinoma who underwent cystectomy or transurethral resection of bladder tumor (TURBT) for bladder cancer between January 2011 and July 2017 were evaluated. Clinical data and follow-up information were obtained from medical records. Formalin-fixed, paraffin-embedded surgical specimens were used for immunohistochemical staining for p16, p53, and p63. Human papillomavirus detection was evaluated by PCR. Statistical analysis was performed, and statistical significance was set at p<0.05. Finally, decision trees were built to classify patients’ prognostic features. Leave-one-out cross-validation was used to test the generalizability of the model. Results Neither direct HPV detection nor its indirect marker (p16 protein) was identified in most cases. The absence of p16 was correlated with less aggressive histological grading (p=0.040). The positive p16 staining detection found only in pT1 and pT2 cases in our sample suggests a possible role for this tumor suppressor protein in the initial stages of bladder squamous cell carcinoma. The decision trees constructed described the relationship between clinical features, such as hematuria/dysuria, the level of tumor invasion, HPV status, lymphovascular invasion, gender, age, compromised lymph nodes, and tumor degree differentiation, with high classification accuracy. Conclusion The algorithm classifier approach established decision pathways for semi-automatic tumor histological classification, laying the foundation for tailored semi-automated decision support systems for pathologists.

ABSTRACT Objective: To conduct an epidemiologic review, analyzing treatment, evolution, and survival of soft tissue sarcomas. Methods: Retrospective study based on medical records of patient with STS treated by the Orthopedic Oncology Group at the Santa Casa de São Paulo, from 2006 to 2019. Data from 121 patients were analyzed according to age, sex, histological type, tumor location, treatment, previous surgery in a non-specialized service, local recurrences, lung metastases, and survival analysis. Results: The most frequent location was the thigh. Patients who underwent surgery with a non-specialized group had higher rates of local recurrence and those with pulmonary metastasis had a lower survival rate. Conclusion: STS can occur at any age and the prevalence of the histological type depends on the patients’ age group. Level of Evidence II, Prognostic Study.

RESUMO Objetivo: Conduzir uma avaliação epidemiológica analisando tratamento, evolução e sobrevida dos sarcomas de partes moles (SPMs). Métodos: Estudo retrospectivo de prontuários de pacientes com SPM tratados pelo Grupo de Oncologia Ortopédica da Santa Casa de Misericórdia de São Paulo, no período de 2006 a 2019. Foram analisados os dados de 121 pacientes referentes a idade, sexo, tipo histológico, localização do tumor, tratamento, cirurgia prévia em serviço não especializado, presença de recidivas, metástases pulmonares e análise de sobrevida. Resultados: A localização mais frequente foi a coxa. Verificou-se que pacientes que realizaram cirurgia com grupo não especializado tiveram maiores índices de recidiva local, e aqueles com metástase pulmonar tiveram menor sobrevida. Conclusão: Os SPMs podem ocorrer em qualquer idade, e a prevalência do tipo histológico depende da faixa etária dos pacientes. Nível de Evidência II, Estudo Prognóstico.

Abstract Objective to investigate self-perception of oral conditions and associated factors in rural quilombola older people in northern Minas Gerais, Brazil. Method This is an analytical and cross-sectional population-based study, in which cluster sampling with probability proportional to size (n=406) was used. Data collection involved conducting interviews and clinical dental examinations. Self-perception of oral conditions was assessed using the GOHAI (Geriatric Oral Health Determination Index). Results Most older people self-perceived oral health as excellent (46.3%) or regular (30.2%). Those surveyed also revealed precarious oral health and restricted access to dental services. In the multiple analysis, significant associations (p˂0.05) were found between regular GOHAI and variables related to the location of the last consultation and use of prosthesis, as well as between poor GOHAI and variables related to marital status, religion, reason for last consultation, CPO-D index and use of prosthesis. Conclusion A significant portion of the quilombola older people showed a more positive self-assessment of oral health, which differs from the professionally verified dental condition. It was also found that the report of poor perception of oral conditions was strongly associated with poorer oral health among those investigated.

Resumo Objetivo investigar a autopercepção das condições bucais e fatores associados em idosos quilombolas rurais do norte de Minas Gerais, Brasil. Método Trata-se de um estudo analítico e transversal de base populacional, no qual utilizou-se uma amostragem por conglomerados com probabilidade proporcional ao tamanho (n=406). A coleta de dados envolveu a realização de entrevistas e exames clínicos odontológicos. A autopercepção das condições bucais foi avaliada por meio do GOHAI (Índice de Determinação da Saúde Bucal Geriátrica). Resultados A maioria dos idosos autopercebeu a saúde bucal como ótima (46,3%) ou regular (30,2%). Os pesquisados revelaram ainda precária saúde bucal e acesso restrito aos serviços odontológicos. Verificaram-se, na análise múltipla, associações significantes (p˂0,05) entre GOHAI regular e variáveis relativas ao local da última consulta e uso de prótese, bem como entre GOHAI ruim e variáveis atinentes ao estado conjugal, religião, motivo da última consulta, índice CPO-D e uso de prótese. Conclusão Parcela expressiva dos idosos quilombolas manifestou uma autoavaliação mais positiva da saúde bucal, divergente do quadro odontológico constatado profissionalmente. Constatou-se ainda que o relato de percepção ruim das condições bucais esteve fortemente associado a uma saúde bucal mais precária entre os investigados.

ABSTRACT Trees transport water from underground to the atmosphere through the evapotranspiration process. Climate change can significantly compromise this process due to changes in land use, such as deforestation. This study aimed to characterize the hydraulic and anatomical attributes of Jacaranda copaia (Aubl.) D. Don (Bignoniaceae), in the Southwestern Brazilian Amazon. For this purpose, the xylem vulnerability curve of this species was described. The frequency and diameter of the xylem vessels and the stomata density were also measured. Finally, a hydraulic attribute of Jacaranda copaia was compared to other species at global, tropical, and Amazonian levels. The findings show that, in the region studied, the species Jacaranda copaia has diffuse-porous woods and numerous vessels (average vessel ranging from 8 to 14 nº/mm2) with small (<50µm) to medium (between 100 and 200 µm) diameters. The average stomatal density ranged from 289 to 309 stomata/mm2. The xylem hydraulic resistance to embolism (Ψ50) ranged from -0.814 to -2.400 MPa, with relatively narrow hydraulic safety margins (HSM50 ranging from -0.312 to 1.122; HSM88 ranging from 0.204 to 1.709). The average values of Ψ50 detected were similar to a large percentage of arboreal species at global, tropical, and Amazonian levels. Possibly, the studied species presents a more “risky” hydraulic strategy, with relatively narrow hydraulic safety margins, due to its dynamic character of fast growth, typical of pioneer species.

RESUMO As árvores transportam água do subsolo para a atmosfera através do processo de evapotranspiração. As mudanças climáticas podem comprometer significativamente esse processo devido a mudanças no uso da terra decorrentes, por exemplo, do desmatamento. O objetivo deste estudo foi caracterizar os atributos hidráulicos e anatômicos de Jacaranda copaia (Aubl.) D. Don (Bignoniaceae) no sudoeste da Amazônia brasileira. Para tanto, foi descrita a curva de vulnerabilidade do xilema desta espécie. A frequência e o diâmetro dos vasos do xilema e a densidade dos estômatos também foram medidos. Finalmente, um atributo hidráulico de Jacaranda copaia foi comparado a outras espécies em nível global, tropical e amazônico. Os achados mostram que, na região estudada, a espécie Jacaranda copaia possui lenhos de porosidade difusa e vasos numerosos (vasos médios variando de 8 a 14 nº/mm2) com diâmetros pequenos (<50µm) a médios (entre 100 e 200 µm). A densidade estomática média variou de 289 a 309 estômatos/mm2. A resistência hidráulica do xilema à embolia (Ψ50) variou de -0.814 a -2.400 MPa, com margens de segurança hidráulica relativamente estreitas (MSH50 variando de -0.312 a 1.122; MSH88 variando de 0.204 a 1.709). Em geral, os valores médios de Ψ50 detectados foram semelhantes a uma grande porcentagem de espécies arbóreas em nível global, tropical e amazônico. Possivelmente, a espécie estudada apresenta uma estratégia hidráulica mais “arriscada” (ou seja, margens de segurança hidráulica relativamente estreitas), devido ao seu caráter dinâmico de crescimento rápido, típico de espécies pioneiras.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

ABSTRACT Dry conditioning and sucrose pulsing are techniques used to improve the durability of flower stems. Dry conditioning helps to balance the osmotic potential of the flower stems and can be applied after harvest and transportation. The objective was to evaluate how different dry conditioning times followed by sucrose pulsing may affect the postharvest quality, durability, and physiological aspects of torch ginger flower stems. For this purpose, flower stems were collected and submitted to dry conditioning for different periods: 0-h, 3-h, 6-h, 12-h, and 24-h. Every 3 days, visual quality, percentage of true flowers, absorption rate, water content, fresh and dry weights, and colorimetric parameters were evaluated. The concentration of pigments, biochemistry of the antioxidant system, and macromolecules were analyzed. Dry conditioning for more than 12-h is not recommended as it leads to a loss of quality and durability in torch ginger flower stems and accelerates senescence. The absorption rate decreases and pigments break down after this period, while H2O2 and lipid peroxidation concentrations increase. Furthermore, sugar and protein reserves are consumed during senescence. It is recommended to hydrate harvested stems immediately to avoid the negative effects of dry conditioning on postharvest quality and durability.

RESUMEN Objetivo: Reflexionar sobre la infodemia de la COVID-19 a la luz de la Teoría de la Complejidad de Edgar Morin y sus tres principios fundamentales, a saber, el principio dialógico, el organizativo y el hologramático de la recursividad. Metodología: Se trata de un ensayo teórico con carácter reflexivo de la literatura sobre la infodemia del COVID-19 a la luz de la Teoría de la Complejidad de Edgar Morin. Resultados: Interrelacionando el principio dialógico con la infodemia, se puede reflexionar sobre la relación de la compleja ambivalencia entre la desinformación y la información científicamente validada y los diversos contenidos disipados en los medios. Cabe destacar que es necesario realizar una síntesis coherente y confiable de los contenidos abordados y ampliamente difundidos. La infodemia del COVID-19 está sumergida en una intención que se da entre líneas mediáticas y en esa intención hay una participación directa de la sociedad. Se entiende que la desinformación se expande a medida que aumenta la producción de contenidos. En ese sentido, la desinformación produce la infodemia que, en consecuencia, también es producida por la desinformación. Es posible reflexionar sobre la infodemia a partir de la noción de que puede influir y ser influenciada por el conjunto, involucrando así cuestiones que cruzan la salud pública, la economía, la política, al tiempo que es fomentada e influenciada por estos ejes específicos. Consideraciones finales: Los principios del pensamiento complejo son elementos que ayudan a la comprensión del fenómeno infodémico y su influencia en el contexto informacional. Se espera que este estudio reflexivo pueda contribuir a mitigar las repercusiones de la infodemia en la cotidianidad de los usuarios de las redes de información.

ABSTRACT Objective: To reflect on the COVID-19 infodemic in the light of Edgar Morin's Complexity Theory and its three main principles, namely the dialogic principle, organizational and hologrammatic recursion. Methodology: This is a theoretical essay with a reflective character of the literature on the COVID-19 infodemic in the light of Edgar Morin's Complexity Theory. Result: Interrelating the dialogic principle with the infodemic, one can reflect on the relationship of the complex ambivalence between disinformation and scientifically validated information and the various contents dissipated in the media. It is noteworthy that it is necessary to carry out a coherent and reliable synthesis of the contents covered and widely disseminated. The COVID-19 infodemic is submerged in an intention that occurs between the lines of the media, and in this intention, there is direct participation by society. It is understood that disinformation increases as the production of content increases, in this sense, disinformation produces the infodemic which, consequently, is also produced by disinformation. It is possible to reflect on the infodemic through the notion that it can influence and be influenced by the whole, thus involving issues that cross public health, the economy, politics, at the same time that it is fostered and influenced by these specific axes. Final considerations: the principles of complex thinking are elements that help the understanding of the infodemic phenomenon and its influence in the informational context. It is hoped that this reflective study can contribute to mitigate the repercussions of the infodemic in the daily lives of users of information networks.

RESUMO Objetivo: Refletir sobre a infodemia da COVID-19 sob a luz da Teoria da Complexidade de Edgar Morin e seus três principais principios, a saber o princípio dialógico, da recursão organizacional e hologramático. Metodologia: Trata-se de ensaio teórico de caráter reflexivo da literatura acerca da infodemia de COVID-19 sob a luz da Teoria da Complexidade de Edgar Morin. Resultados: Interrelacionando o princípio dialógico com a infodemia, pode-se refletir sobre a relação da ambivalência complexa entre a desinformação e informações validadas cientificamente e dos diversos conteúdos dissipados nos meios de comunicação. Ressalta-se que é necessário realizar uma síntese coerente e confiável sobre os conteúdos abordados e amplamente difundidos. A infodemia de COVID-19 submerge de uma intenção que ocorre nas entrelinhas dos meios de comunicação, e nessa intencionalidade há participação direta da sociedade. Compreende-se que a desinformação se amplia na medida em que a produção de conteúdo aumenta, nesse sentido, a desinformação produz a infodemia que, consequentemente, é produzida também pela desinformação. É possível refletir sobre a infodemia através da noção de que está pode influenciar e ser influenciada pelo todo, envolvendo assim, questões que atravessam a saúde pública, a economia, a política, ao mesmo tempo que é fomentada e influenciada por esses eixos específicos. Considerações finais: Os princípios do pensamento complexo, constituem-se como elementos que auxiliam a compreensão do fenômeno infodemia sua influência no contexto informacional. Espera-se que este estudo reflexivo possa contribuir para que sejam mitigadas as repercussões da infodemia no cotidiano dos usuários das redes de informação.

SUMMARY OBJECTIVE: The aim of this study was to assess the inter-reliability of the Braden scale and its subscales for different patients assisted in the intensive care unit. We hypothesized that the Braden scale has low reliability in different populations. METHODS: This reliability study involved the Braden scale in intensive care unit of a hospital. A total of 200 patients were admitted to the intensive care unit in four different groups: neurological patients, sepsis, elderly, and adults affected by trauma. The Braden scale is a tool composed of six subscales for patient assessment: sensory perception, humidity, activity, mobility, nutrition, and friction. The total score was also calculated. The Braden scale was applied by two different nurses with an interval of 20–30 min between applications. RESULTS: For all populations, kappa values considered unsuitable were observed for most categories of the Braden scale, ranging from 0.06–0.25. Only for the total Braden scale score was moderate reliability identified in all groups evaluated, with intraclass correlation coefficient values ranging from 0.48–0.75. CONCLUSIONS: Braden scale is not a reliable tool to be used in the intensive care unit, and we do not recommend the use of this scale to assess the risk of developing pressure injury.

Abstract Microbial biomass is considered a renewable and environmentally friendly resource. Thus, the research conducted a kinetic study and thermodynamic equilibrium modeling of the cobalt (Co) and manganese (Mn) bioadsorption process using the Rhodococcus opacus (RO) strain as a biosorbent. The inactive biomass subjected to 0.1 M NaOH pretreatment was brought into contact with synthetic solutions of Co and Mn. The experimental data for the Co(II) and Mn(II) bioadsorption process were fit to the Langmuir model with kads of 0.65 and 0.11 L.mg-1, respectively. A better statistical fit was also obtained for the pseudo-second order kinetic model (R2Co(II) = 0.994 and R2Mn(II) = 0.995), with 72.3% Co(II) and 80% Mn(II) removals during the first 10 min. In addition, a higher affinity of RO for the Co(II) ion was observed, with maximum uptake values of 13.42 mg.g-1; however, a higher adsorption rate was observed for Mn(II) ion (k = 0.21 g.mg-1.min-1 at 318 K). The bioadsorption process was spontaneous and dependent on temperature, being endothermic and irreversible for the Co(II) ion (∆H = 2951.91 J.mol-1) and exothermic and reversible for the Mn(II) ion (∆H = -2974.8 J.mol-1). The kinetic and thermodynamic equilibrium modeling allowed to identify the main mechanisms involved in the biosorption process of both metals.
