Abstract Objective To describe the conceptual exercise of reflecting on the possibilities and particularities of the participation of Lusophone schools of nursing in the Nursing Knowledge Network. Method An analysis was conducted using information obtained from an environmental scan of institutional resources following the conceptual framework by Prug and Prusak on the knowledge networks. The learnings reported in the analysis are based on the collected information and reflections on the positive and negative aspects of participation, while proposing possible solutions for an action plan. Results There is interest in the internationalization of research and collaborative work both as institutional actions to support nursing research and potential benefits due to participation in the Network. The collaborative work has potential to increase the impact of research, expedite dissemination and use of results both in education and in clinical practice, broadening the horizons of Lusophone nursing science. Conclusion and Implications for practice Participation of these institutions in the Network offers numerous possibilities to demonstrate the originality, creativity and expertise of their teaching and research practice, encouraging the sharing of ideas and practices. The practice of scientific production in all its scenarios by educators and students can be improved through refined ways of thinking, creating, producing, and disseminating knowledge.

BACKGROUND Chikungunya is a mosquito-borne virus that has been causing large outbreaks in the Americas since 2014. In Brazil, Asian-Caribbean (AC) and East-Central-South-African (ECSA) genotypes have been detected and lead to large outbreaks in several Brazilian states. In Rio Grande do Sul (RS), the southernmost state of Brazil, the first cases were reported in 2016. OBJECTIVES AND METHODS We employed genome sequencing and epidemiological investigation to characterise the Chikungunya fever (CHIKF) burden in RS between 2017-2021. FINDINGS We detected an increasing CHIKF burden linked to travel associated introductions and communitary transmission of distinct lineages of the ECSA genotype during this period. MAIN CONCLUSIONS Until 2020, CHIKV introductions were most travel associated and transmission was limited. Then, in 2021, the largest outbreak occurred in the state associated with the introduction of a new ECSA lineage. CHIKV outbreaks are likely to occur in the near future due to abundant competent vectors and a susceptible population, exposing more than 11 million inhabitants to an increasing infection risk.

RESUMO Estudantes-atletas de futebol são expostos ao desafio de conciliação entre as carreiras esportiva e acadêmica. Essa situação de dupla carreira impõe tensões que podem resultar em evasão ou mal desempenho. Nosso objetivo foi analisar os desafios de estudantes-atletas de futebol no Brasil na conciliação entre as carreiras acadêmica e esportiva. Considerando a dupla carreira como um problema social, este ensaio é fundamentado na literatura sobre esse fenômeno e em categorias da sociologia reflexiva de Pierre Bourdieu. Como principais resultados, tem-se que a recorrente priorização da carreira esportiva se relaciona: às origens socioeconômicas dos indivíduos; ao poder simbólico dos clubes sobre as escolas; à busca por ascensão social; aos sistemas esportivo e escolar que reproduzem desigualdades.

ABSTRACT Soccer student-athletes are exposed to the challenge of reconciling sports and academic careers. This dual-career situation imposes tensions that can result in dropout or poor performance. Our aim was to analyze the challenges faced by soccer student-athletes in Brazil when reconciling academic and sport careers. Considering dual career as a social issue, this essay is based on the literature about this phenomenon and on categories from Pierre Bourdieu’s reflective sociology. As main results, the recurring prioritization of the sport career is related to the individuals’ socioeconomic origins; the symbolic power of clubs over schools; the search for social ascension; sports and school systems that reproduce inequalities. studentathletes student athletes careers dualcareer performance issue Bourdieus Bourdieu s sociology results individuals origins schools ascension inequalities

ABSTRACT Studies related to climate change and agricultural value chains have in common the growing concern on conserving water resources. Thus, the concept of the water footprint stands out, which measures the amount of water (in volume) necessary to produce a unit (in mass) of a given product. Among Brazilian agricultural activities, coffee farming emerges as one of the most important, even though the crop is sensitive to potential climatic changes, especially to the increase in temperature and periods of drought. An alternative to mitigate the effects of climate change is shade management, which is common in agroforestry systems. Therefore, the objective of this study was to evaluate the influence of shade management on the water footprint of coffee activity in the region of “Matas de Minas”. The water footprint was calculated for the field and product processing phase. Despite reducing the evapotranspiration of the coffee plant, shade management provided an increase in the water footprint, since it decreased the crop yield. The water footprint data obtained are expressive, with a calculated value of 13,862 m3 t-1 for full sun management and 16,895 m3 t-1 for shade management, in which both are the most recommended for the agricultural sector.

Abstract Objective: To provide guidelines on the coronavirus disease 2019 (COVID-19) vaccination in patients with immune-mediated rheumatic diseases (IMRD) to rheumatologists considering specific scenarios of the daily practice based on the shared-making decision (SMD) process. Methods: A task force was constituted by 24 rheumatologists (panel members), with clinical and research expertise in immunizations and infectious diseases in immunocompromised patients, endorsed by the Brazilian Society of Rheumatology (BSR), to develop guidelines for COVID-19 vaccination in patients with IMRD. A consensus was built through the Delphi method and involved four rounds of anonymous voting, where five options were used to determine the level of agreement (LOA), based on the Likert Scale: (1) strongly disagree; (2) disagree, (3) neither agree nor disagree (neutral); (4) agree; and (5) strongly agree. Nineteen questions were addressed and discussed via teleconference to formulate the answers. In order to identify the relevant data on COVID-19 vaccines, a search with standardized descriptors and synonyms was performed on September 10th, 2021, of the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and LILACS to identify studies of interest. We used the Newcastle–Ottawa Scale to assess the quality of nonrandomized studies. Results: All the nineteen questions-answers (Q&A) were approved by the BSR Task Force with more than 80% of panelists voting options 4—agree—and 5—strongly agree—, and a consensus was reached. These Guidelines were focused in SMD on the most appropriate timing for IMRD patients to get vaccinated to reach the adequate covid-19 vaccination response. Conclusion: These guidelines were developed by a BSR Task Force with a high LOA among panelists, based on the literature review of published studies and expert opinion for COVID-19 vaccination in IMRD patients. Noteworthy, in the pandemic period, up to the time of the review and the consensus process for this document, high-quality evidence was scarce. Thus, it is not a substitute for clinical judgment.

Resumo O objetivo deste estudo foi determinar a ocorrência de patógenos transmitidos por carrapatos (Ehrlichia canis, Babesia vogeli, Hepatozoon spp. e Rickettsia spp.) em cães na Vila de Jericoacoara, região costeira do Ceará, Brasil. Amostras de sangue foram coletadas de 153 animais e analisadas por métodos moleculares e sorológicos. Sessenta animais foram encontrados infectados ou expostos a pelo menos a um dos patógenos estudados. Babesia vogeli foi o patógeno mais prevalente (15%), seguido por E. canis (13,7%) e Hepatozoon spp. (11,8%), que foi identificado como Hepatozoon canis por sequenciamento. Vinte cães (13%) foram sororreativos à Rickettsia spp. Rhipicephalus sanguineus sensu lato foi observado em 11,8% dos animais. Houve associações entre idade (<3 anos) e positividade para B. vogeli, e entre habitação (cães de rua) e positividade para H. canis. Também houve associações entre anemia e infecção por H. canis, e entre leucopenia e exposição a Rickettsia spp. Não foi detectada associação entre alterações clínicas e infecção ou exposição aos patógenos estudados. Os resultados confirmaram que patógenos de importância veterinária estão circulando no nordeste do Brasil e mostraram que cães estão expostos a espécies de Rickettsia com potencial zoonótico, indicando a necessidade de medidas de controle do vetor.
Abstract The aim of this study was to determine the occurrence of tick-borne pathogens (Ehrlichia canis, Babesia vogeli, Hepatozoon spp. and Rickettsia spp.) in dogs in Vila de Jericoacoara, coastal region of Ceará, Brazil. Blood samples were collected from 153 animals and analyzed using molecular and serological methods. Sixty animals were found to be infected or exposed to at least one of the pathogens studied. Babesia vogeli was the most prevalent pathogen (15%), followed by E. canis (13.7%) and Hepatozoon spp. (11.8%), which was identified as Hepatozoon canis through sequencing. Twenty dogs (13%) were seroreactive to Rickettsia spp. Rhipicephalus sanguineus sensu lato was observed on 11.8% of the animals. There were associations between age (< 3 years old) and positivity for B. vogeli, and between habitation (stray dogs) and positivity for H. canis. There were also associations between anemia and infection with H. canis, and between leukopenia and exposure to Rickettsia spp. No association was detected between clinical alterations and infection with or exposure to the pathogens studied. The results confirmed that pathogens of veterinary importance are circulating in northeastern Brazil and showed that dogs are exposed to Rickettsia species with zoonotic potential, thus indicating a need for vector control measures.

ABSTRACT Background: Domestic pigeons carry pathogens in their droppings, posing a potential public health problem. Methods: The phenotypic and genotypic antimicrobial resistances of Staphylococcus aureus and Enterococcus faecium in the feces of urban pigeons near hospitals with intensive care units were measured. Results: Twenty-nine samples showed Enterococcus growth, whereas one was positive for S. aureus. The S. aureus isolate was sensitive to the antibiotics tested via antibiogram, however resistance genes were identified. E. faecium isolates showed phenotypic resistance to gentamicin, erythromycin, and ciprofloxacin. Conclusions: Antimicrobial profiles harmful to health were demonstrated in bacterial pathogens isolated from the external environment of hospitals.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Abstract Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China’s Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients’ overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.

RESUMO Introdução: A terapia de substituição renal continua associada a altas taxas de hospitalização e baixa qualidade de vida. A morbimortalidade por todas as causas na terapia de substituição renal é superior a 20% ao ano, sendo 44 vezes maior quando a diabetes está presente e mais de 10 vezes a da população em geral. Independentemente do tratamento, a sobrevida em 5 anos é de 40%, superando muitos tipos de câncer. A irisina é um hormônio que converte tecido adiposo branco em tecido adiposo bege, agregando efeitos positivos como o controle de massa gorda, tolerância à glicose, resistência à insulina, prevenção de perda muscular e redução da inflamação sistêmica. Objetivos: Determinar os níveis séricos de troponina I em pacientes em hemodiálise submetidos ao pré-condicionamento isquêmico remoto (PCIR) associado à expressão da irisina. Métodos: Estudo clínico prospectivo, randomizado, duplo-cego, com pacientes com doença renal crônica submetidos à hemodiálise por um período de 6 meses. Os níveis de troponina I, IL-6, uréia, TNF-α e creatinina foram determinados a partir de amostras de sangue. As expressões de irisina, tioredoxina, Nf-kb, GPX4, selenoproteína e GADPH foram também avaliadas por RT-PCR. Resultados: Foram analisadas amostras de 14 pacientes hipertensos, 9 (64,3%) dos quais eram diabéticos tipo 2, com idades entre 44 e 64 anos e 50% de cada gênero. A diferença entre os níveis pré e pós-intervenção de troponina I não foi significativa. Não houve diferenças entre os grupos PCIR e controle, exceto pela IL-6, embora tenha sido observada correlação significativa entre irisina e troponina I. Conclusão: O pré-condicionamento isquêmico remoto não modificou a expressão de irisina ou troponina I, independentemente do tempo de coleta.
ABSTRACT Background: Renal replacement therapy continues to be related to high hospitalization rates and poor quality of life. All-cause morbidity and mortality in renal replacement therapy in greater than 20% per year, being 44 times greater when diabetes is present, and over 10 times that of the general population. Regardless of treatment, the 5-year survival is 40%, surpassing many types of cancers. Irisin is a hormone that converts white adipose tissue into beige adipose tissue, aggregating positive effects like fat mass control, glucose tolerance, insulin resistance, prevention of muscle loss, and reduction in systemic inflammation. Objectives: To determine the serum levels of troponin I in hemodialysis patients submitted to remote ischemic preconditioning (RIPC) associated with irisin expression. Methods: This was a prospective, randomized, double-blind clinical trial with patients with chronic kidney disease submitted to hemodialysis for a 6-month period. Troponin I, IL-6, urea, TNF-α, and creatinine levels were determined from blood samples. The expressions of irisin, thioredoxin, Nf-kb, GPX4, selenoprotein and GADPH were also evaluated by RT-PCR. Results: Samples from 14 hypertensive patients were analyzed, 9 (64.3%) of whom were type 2 diabetics, aged 44-64 years, and 50% of each sex. The difference between pre- and post-intervention levels of troponin I was not significant. No differences were verified between the RIPC and control groups, except for IL-6, although a significant correlation was observed between irisin and troponin I. Conclusion: Remote ischemic preconditioning did not modify irisin or troponin I expression, independent of the time of collection.

RESUMO O estudo teve por objetivo determinar a despesa com energia elétrica na lavagem de filtro rápido de uma estação de tratamento de água (ETA), cuja vazão é de 45 L/s. Para isso, foi realizado monitoramento hidroenergético para a análise do desempenho no bombeamento de água de lavagem. Adicionalmente, foi monitorada a qualidade da água do efluente de três lavagens no filtro 4 e realizado um levantamento das informações tarifárias de energia elétrica da unidade de tratamento. Com os resultados obtidos, observou-se que os valores de turbidez do efluente, ao final das três lavagens, no caso, 31, 30 e 27 UNT, não atingiram os limites mínimos recomendados na literatura técnica, que é de, pelo menos, 15 UNT. Foi observada também a dificuldade de prolongamento do tempo de lavagem, a fim de alcançar o padrão da literatura, pois o reservatório elevado (REL) de água de lavagem (água tratada), também alimenta a rede de distribuição, e poderia esvaziar completamente. Levando em conta essas limitações e a qualidade final do efluente de lavagem, observou-se que as lavagens devem ser finalizadas aos 380 segundos (6,3 minutos), tempo que consome um volume de 23,36 m3/lavagem. A despesa de água de lavagem foi calculada em 1,36 R$/m3, o que resultou no valor de 31,83 R$/lavagem. Para as lavagens de todos os filtros da estação, as despesas foram de 254,64 R$/dia, 7.639,20 R$/mês e 91.670,4 R$/ano. Esses valores são considerados elevados para o sistema de tratamento estudado.
ABSTRACT This paper aims to determine the cost of electricity for rapid filter backwashing procedures at water treatment plants, whose flow rate is 45 L/s. Flow and electricity consumption were monitored in order to analyze the performance of the pumping systems. Additionally, the effluent water quality of three washes was monitored in filter 4 and a survey of the electricity fare data of the treatment unit was carried out. With the results obtained, it was observed that the effluent turbidity values at the end of the three washes, in this case 31, 30, and 27 NTU, did not reach the minimum values recommended in the technical literature, which is at least 15 NTU. It was also observed the impossibility of prolonging the backwashing time in order to reach the standard of the literature, due to the double function of the elevated washing water reservoir (treated water), whose main purpose is to provide treated water to the water distribution network. Taking into account these limitations and the final quality of the wash effluent, it was observed that the duration of backwashing procedures should be around 380 seconds (6.3 minutes), consuming 23.36 m3/wash. The backwashing procedure cost was estimated at R$ 1.36/m3, which resulted in R$ 31.83/wash. Considering the whole filtration unit, the backwashing procedure cost was R$ 254.64/day, R$ 7,639.20/month, and R$ 91,670.4/year. This value can be classified as too expensive considering the treatment plant studied.

ABSTRACT Hexapods, commonly known as insects, are a neglected taxonomic group in the Fernando de Noronha archipelago, with unanswered questions about their species richness and the ecological processes in which they are involved (e.g., colonization, introduction, establishment, and extinction). Herein, we provide an updated Hexapod checklist with current nomenclatural combinations. The entomofauna of the Fernando de Noronha archipelago is currently composed of 453 species in 21 orders. The orders, and their respective number of species, are: Blattaria (9), Coleoptera (118), Collembola (29), Dermaptera (3), Diplura (1), Diptera (134), Embioptera (1), Hemiptera (29), Hymenoptera (59), Isoptera (2), Lepidoptera (25), Mantodea (1), Neuroptera (3), Odonata (5), Orthoptera (11), Phasmatodea (1), Phthiraptera (6), Psocoptera (3), Siphonaptera (1), Thysanoptera (10), and Zygentoma (2). The archipelago has 263 new taxon records (family + genera + species). Thirty-eight species (3.39%) were described from local specimens and most of them are likely endemic species. This study more than doubles our knowledge (from the previous 190 records) of the entomofauna in this large Brazilian archipelago. This study also provides a baseline for studies on its conservation status and for implementing future environmental management programs.

RESUMO O zinco (Zn) é um dos micronutrientes mais deficientes em solos agrícolas no Brasil. Objetivou-se nesse estudo avaliar a nutrição, produção de grãos e exportação de nutrientes em função da fertilização de Zn em feijoeiro-comum (Phaseolus vulgaris L.) cultivado sob sistema de plantio direto. Dois experimentos de campo foram conduzidos usando a cultivar IPR Campos Gerais (feijão carioca) e a cultivar BRS Esteio (feijão preto). Os tratamentos foram compostos pela aplicação de Zn no solo durante a semeadura e pela pulverização foliar de Zn no estádio fenológico de florescimento. A aplicação de Zn no solo teve efeito sobre o teor foliar de Zn da IPR Campos Gerais, mas não afetou a produtividade de grãos. Entretanto, a pulverização foliar de Zn elevou consideravelmente o teor foliar de Zn, resultando em aumento e redução na produtividade de grãos da IPR Campos Gerais e BRS Esteio, respectivamente. Os teores foliares de N, Ca, S e Mn foram afetados pela aplicação de Zn no solo e/ou foliar, enquanto que os teores foliares de P, K, Mg, Cu e Fe não foram influenciados pelos tratamentos. Considerando os tratamentos que não receberam Zn, as exportações de nutrientes obedeceram à ordem para os macronutrientes N > K > P > Ca ≈ S > Mg e à ordem para os micronutrientes Fe > Mn > Cu > Zn. A pulverização foliar de Zn elevou as exportações de Zn, P, Ca, Mg, S, Mn, Cu e Fe na IPR Campos Gerais, enquanto que a aplicação de Zn no solo resultou em maior exportação de P, K e Mn na BRS Esteio.
ABSTRACT Zinc (Zn) is one of the most deficient plant micronutrients in agricultural crops. The objective of this study was to evaluate plant nutrition, grain yield and nutrient export rate in response to soil and foliar Zn fertilization in common bean (Phaseolus vulgaris L.). Two field experiments in no-till system were carried out using two common bean cultivars, BRS Esteio (black bean) and IPR Campos Gerais (Carioca bean). Treatments were composed of soil Zn application during sowing and foliar Zn spray at flowering stage. Soil Zn application had effect on leaf Zn concentration in IPR Campos Gerais and did not affect grain yield of both cultivars. Foliar Zn spray increased leaf Zn concentration by approximately two times in both cultivars, but negatively affected the grain yield in BRS Esteio. Leaf concentration of N, Ca and S were affected by soil Zn application and leaf concentration of Mn was affected by foliar Zn spray, while leaf concentration of P, K, Mg, Cu and Fe were not influenced by the soil and foliar Zn treatments. In treatments without Zn, the descending order of nutrient export rate from the experimental site was as follows: N > K > P > Ca ≈ S > Mg for macronutrients and Fe > Mn > Cu > Zn for micronutrients. Foliar Zn spray increased the export rate of Zn, P, Ca, Mg, S, Mn, Cu and Fe in IPR Campos Gerais, while soil Zn application resulted in higher export rate of P, K and Mn in BRS Esteio.
