ABSTRACT Phosphites can be considered an additional strategy to be included in disease management programs. Therefore, this study aims to evaluate the application of potassium phosphite (KPhi) in common bean seeds, in the reduction of intensity of root rot (Rhizoctonia solani) and in the compatibility with Rhizobium tropici, a nitrogen-fixing bacterium. The emergence speed index (ESI) and the percentage of total emergence were evaluated in seeds inoculated with R. solani and treated with KPhi. The number of nodules per root system, dry nodule mass, quantified the compatibility Phi x R. tropici, dry mass, nitrogen content, and nitrogen accumulation in the shoots. KPhi promoted a higher ESI and increase in plant stand compared to the control treatment. The number of nodules formed and the nitrogen content and accumulation in the KPhi treatments were similar to control (seeds inoculated with R. tropici). Thus, the treatment of seeds with KPhi provides control of R. solani and is compatible with R. tropici.

RESUMO O uso de fertilizantes revestidos é uma estratégia para melhorar a eficiência da adubação e o rendimento das culturas. No entanto, são necessários estudos para entender a dinâmica no solo dos diferentes tipos de fertilizantes potássicos (K) revestidos. Objetivou-se avaliar a lixiviação, disponibilidade e recuperação de K em colunas de solo após aplicação de fonte convencional KCl e outras fontes de K com tecnologias de revestimento e compactação. O experimento compreendeu quatro tratamentos, constituídos por três fontes de K (KCl convencional; KCl revestido com aditivos e polímeros - KCl-C; e KCl compactado e revestido com aditivos e polímeros - KCl-CC), e um controle sem adubação, com quatro repetições. Os teores de K foram avaliados na solução lixiviada das colunas de solo por 28 dias. Após esse período, foram determinados os teores de K no solo. A ausência de adubação no solo levou a uma redução de 26,5% nos teores de K. As fontes revestidas apresentaram menor dureza de grânulos e maior lixiviação de K em relação ao KCl convencional. A quantidade de K lixiviada foi de 62,2% para KCl-CC, 68,5% para KCl-C e 54,0% para KCl convencional. No entanto, ao final do experimento, os teores de K no solo foram maiores para a fonte KCl-C.

ABSTRACT The use of coated fertilizers is a strategy for improving fertilization efficiency and crop yield. However, further studies are needed to understand the dynamics of different types of coated K fertilizers in the soil. The objective of this study was to evaluate K dynamics in soil columns after the application of conventional KCl and other K sources with coating (KCl-C) and compaction (KCl-CC) combined with the use of additives and polymers. The experiment comprised four treatments, consisting of three sources of K [conventional KCl, KCl coated with additives and polymers (KCl-C), and KCl compacted and coated with additives and polymers (KCl-CC)], and a control without K application, with four repetitions. The K concentration was evaluated in the leached solution collected from the soil columns for 28 days. After this period, the K concentration in the soil was determined. The absence of K fertilization in the soil led to a 26.5% reduction in the K concentration. The coated sources had lower granule hardness and higher K leaching than conventional KCl. The amounts of K leached were 62.2%, 68.5%, and 54.0% for KCl-CC, KCl-C, and conventional KCl, respectively. However, at the end of the experiment, the soil K concentration was higher under the KCl-C treatment.

Resumo Fundamento: O impacto dos fatores de risco (FR) sobre a morbimortalidade por doença cardiovascular (DCV) na maioria dos países de língua portuguesa (PLP) é pouco conhecido. Objetivo: Analisar a morbimortalidade por DCV atribuível aos FR e sua variação nos PLP de 1990 a 2019, a partir de estimativas do estudo Global Burden of Disease (GBD) 2019. Métodos: Avaliamos as mudanças nos FR ocorridas no período, as taxas de mortalidade e os anos de vida perdidos por incapacidade (DALYs), padronizados por idade, entre 1990 e 2019. Realizou-se a correlação entre a variação percentual das taxas de mortalidade e o índice sociodemográfico (SDI) de cada PLP pelo método de Spearman. O valor p<0,05 foi considerado estatisticamente significativo. Resultados: A pressão arterial sistólica (PAS) elevada foi o principal fator de risco para mortalidade e DALY por DCV para todos os PLP. A mortalidade por DCV mostrou uma tendência de redução em 2019, maior em Portugal (-66,6%, IC95% -71,0 - -61,2) e no Brasil (-49,8%, IC95% -52,5 - -47,1). Observou-se tendência à correlação inversa entre SDI e a variação percentual da mortalidade, que foi significativa para os riscos dietéticos (r=-0,70, p=0,036), colesterol LDL elevado (r=-0,77, p=0,015) e PAS elevada (r=-0,74, p=0,023). Conclusões: Além da PAS, os FR dietéticos e metabólicos justificaram uma maior variação da carga de DCV, correlacionada com o SDI nos PLP, sugerindo a necessidade de adoção de políticas de saúde adaptadas à realidade de cada país, visando a redução de seu impacto sobre a população.

Abstract Background: The impact of risk factors (RF) on morbidity and mortality from cardiovascular disease (CVD) for most Portuguese-speaking countries (PSC) is little known. Objectives: We aimed to analyze the morbidity and mortality from CVD attributable to RF and its variation, from 1990 to 2019, in PSC, based on estimates from the Global Burden of Disease (GBD) 2019 study. Methods: We evaluated changes in cardiovascular RF, mortality rates and age-standardized disability-adjusted life years (DALYs) between 1990 and 2019. The correlation between percentage changes in mortality rates and the sociodemographic index (SDI) of each PSC was evaluated by the Spearman method. A p-value <0.05 was considered statistically significant. Results: Elevated systolic blood pressure (SBP) was the main RF for mortality and DALYs for CVD for all PSC. Mortality from CVD showed a downward trend in 2019, more accentuated in Portugal (-66.6%, 95%CI -71.0 - -61.2) and in Brazil (-49.8%, 95%CI -52.5 - -47.1). There was a trend towards an inverse correlation between SDI and the percent change in mortality, which was significant for dietary risks (r=-0.70, p=0.036), high LDL cholesterol (r=-0.77, p=0.015) and high SBP (r=-0.74, p=0.023). Conclusions: In addition to SBP, dietary and metabolic RF justified a greater variation in the burden of CVD correlated with SDI in the PSC, suggesting the need to adopt health policies adapted to the reality of each country, aiming to reduce their impact on population.

OBJECTIVES: Strategic planning for coronavirus disease (COVID-19) care has dominated the agenda of medical services, which have been further restricted by the need for minimizing viral transmission. Risk is particularly relevant in relation to endoscopy procedures. This study aimed to describe a contingency plan for a tertiary academic cancer center, define a strategy to prioritize and postpone examinations, and evaluate the infection rate among healthcare workers (HCWs) in the endoscopy unit of the Cancer Institute of the State of São Paulo (ICESP). METHODS: We created a strategy to balance the risk of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and to mitigate the effects of postponing endoscopic procedures in oncological patients. A retrospective analysis of prospectively collected data on all endoscopies between March and June 2020 compared with those during the same period in 2019 was carried out. All HCWs were interviewed to obtain clinical data and SARS-CoV-2 test results. RESULTS: During the COVID-19 outbreak, there was a reduction of 55% in endoscopy cases in total. Colonoscopy was the most affected modality. The total infection rate among all HCWs was 38%. None of the senior digestive endoscopists had COVID-19. However, all bronchoscopists had been infected. One of three fellows had a serological diagnosis of COVID-19. Two-thirds of all nurses were infected, whereas half of all technicians were infected. CONCLUSIONS: In this pandemic scenario, all endoscopy services must prioritize the procedures that will be performed. It was possible to maintain some endoscopic procedures, including those meant to provide nutritional access, tissue diagnosis, and endoscopic resection. Personal protective equipment (PPE) seems effective in preventing transmission of COVID-19 from patients to digestive endoscopists. These measures can be useful in planning, even for pandemics in the future.

Abstract BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making the first detection of Baryon Acoustic Oscillations (BAO) in the frequency band 980 MHz - 1260 MHz, corresponding to a redshift range 0.127 < z < 0.449. BAO is one of the most powerful probes of cosmological parameters and BINGO was designed to detect the BAO signal to a level that makes it possible to put new constraints on the equation of state of dark energy. The telescope will be built in Paraíba, Brazil and consists of two \thicksim 40m mirrors, a feedhorn array of 50 horns, and no moving parts, working as a drift-scan instrument. It will cover a 15 ^{\circ} ∘ declination strip centered at \sim \delta ∼ δ =-15 ^{\circ} ∘, mapping \sim ∼ 5400 square degrees in the sky. The BINGO consortium is led by University of São Paulo with co-leadership at National Institute for Space Research and Campina Grande Federal University (Brazil). Telescope subsystems have already been fabricated and tested, and the dish and structure fabrication are expected to start in late 2020, as well as the road and terrain preparation.

Carvacrol (CV) and carvacryl acetate (CVA) are bioactive compounds that have anthelmintic action and the nanoencapsulation may be an alternative to potentialize their efficacy. The aim of this work was to nanoencapsulate CV and CVA using chitosan/gums and evaluate cytotoxicity and the anthelmintic activity. A 24 factorial experimental design was performed to determine the influence of gum type (arabic or chichá), amount of surfactant and the number of layers in the nanoencapsulation degree. CVA and CV presented encapsulation efficiency (EE) optimum values of 90 and 20% (experiments 8 and 9), respectively. The monolayer and bilayer formulations presented maximum size of 479 and 811 nm, respectively. Nanoencapsulated CVA (nCVA) with bilayer coating and higher surfactant levels showed good thermal stability and no toxicity. In vitro kinetics for nCVA with chitosan/chichá gum showed slower release profiles than nCVA with chitosan/gum arabic, with 50% release after 30 and 20 h, respectively. CVA and nCVA at a concentration of 150 µg mL−1 reduced the motility of H. contortus adult nematodes by 100 and 91.7%, respectively. In summary, nCVA chitosan/chichá gum showed high encapsulation efficiency, favorable release rate and anthelmintic activity against H. contortus.

OBJECTIVES: Brazil has rapidly developed the second-highest number of COVID-19 cases in the world. As such, proper symptom identification, including gastrointestinal manifestations, and relationship to health outcomes remains key. We aimed to assess the prevalence and impact of gastrointestinal symptoms associated with COVID-19 in a large quaternary referral center in South America. METHODS: This was a single-center cohort study in a COVID-19 specific hospital in São Paulo, Brazil. Consecutive adult patients with laboratory confirmed SARS-CoV-2 were included. Baseline patient history, presenting symptoms, laboratory results, and clinically relevant outcomes were recorded. Regression analyses were performed to determine significant predictors of the gastrointestinal manifestations of COVID-19 and hospitalization outcomes. RESULTS: Four-hundred patients with COVID-19 were included. Of these, 33.25% of patients reported ≥1 gastrointestinal symptom. Diarrhea was the most common gastrointestinal symptom (17.25%). Patients with gastrointestinal symptoms had higher rates of concomitant constitutional symptoms, notably fatigue and myalgia (p<0.05). Gastrointestinal symptoms were also more prevalent among patients on chronic immunosuppressants, ACE/ARB medications, and patient with chronic kidney disease (p<0.05). Laboratory results, length of hospitalization, ICU admission, ICU length of stay, need for mechanical ventilation, vasopressor support, and in-hospital mortality did not differ based upon gastrointestinal symptoms (p>0.05). Regression analyses showed older age [OR 1.04 (95% CI, 1.02-1.06)], male gender [OR 1.94 (95% CI, 1.12-3.36)], and immunosuppression [OR 2.60 (95% CI, 1.20-5.63)], were associated with increased mortality. CONCLUSION: Based upon this Brazilian study, gastrointestinal manifestations of COVID-19 are common but do not appear to impact clinically relevant hospitalization outcomes including the need for ICU admission, mechanical ventilation, or mortality.

ABSTRACT Background: The II Brazilian Consensus on Gastric Cancer by the Brazilian Gastric Cancer Association (ABCG) was recently published. On this occasion, several experts in gastric cancer expressed their opinion before the statements presented. Aim: To present the ABCG Guidelines (part 1) regarding the diagnosis, staging, endoscopic treatment and follow-up of gastric cancer patients. Methods: To forge these Guidelines, the authors carried out an extensive and current review regarding each statement present in the II Consensus, using the Medline/PubMed, Cochrane Library and SciELO databases with the following descriptors: gastric cancer, staging, endoscopic treatment and follow-up. In addition, each statement was classified according to the level of evidence and degree of recommendation.

RESUMO Racional: Desde a publicação do primeiro Consenso Brasileiro sobre Câncer Gástrico em 2012 realizado pela Associação Brasileira de Câncer Gástrico (ABCG), novos conceitos sobre o diagnóstico, estadiamento, tratamento e seguimento foram incorporados. Objetivo: Promover uma atualização aos profissionais que atuam no combate ao câncer gástrico (CG) e fornecer diretrizes quanto ao manejo dos pacientes portadores desta afecção. Métodos: Cinquenta e nove especialistas responderam 67 declarações sobre o diagnóstico, estadiamento, tratamento e prognóstico do CG com cinco alternativas possíveis: 1) concordo plenamente; 2) concordo parcialmente; 3) indeciso; 4) discordo e 5) discordo fortemente. Foi considerado consenso a concordância de pelo menos 80% da soma das respostas “concordo plenamente” e “concordo parcialmente”. Este artigo apresenta apenas as respostas dos especialistas participantes. Os comentários sobre cada declaração, assim como uma revisão da literatura serão apresentados em publicações futuras. Resultados: Das 67 declarações, houve consenso em 50 (74%). Em 10 declarações, houve concordância de 100%. Conclusão: O tratamento do câncer gástrico evoluiu consideravelmente nos últimos anos. Este consenso reúne princípios consolidados nas últimas décadas, novos conhecimentos adquiridos recentemente, assim como perspectivas promissoras sobre o manejo desta doença.

ABSTRACT Background: Since the publication of the first Brazilian Consensus on Gastric Cancer (GC) in 2012 carried out by the Brazilian Gastric Cancer Association, new concepts on diagnosis, staging, treatment and follow-up have been incorporated. Aim: This new consensus is to promote an update to professionals working in the fight against GC and to provide guidelines for the management of patients with this condition. Methods: Fifty-nine experts answered 67 statements regarding the diagnosis, staging, treatment and prognosis of GC with five possible alternatives: 1) fully agree; 2) partially agree; 3) undecided; 4) disagree and 5) strongly disagree A consensus was adopted when at least 80% of the sum of the answers “fully agree” and “partially agree” was reached. This article presents only the responses of the participating experts. Comments on each statement, as well as a literature review, will be presented in future publications. Results: Of the 67 statements, there was consensus in 50 (74%). In 10 declarations, there was 100% agreement. Conclusion: The gastric cancer treatment has evolved considerably in recent years. This consensus gathers consolidated principles in the last decades, new knowledge acquired recently, as well as promising perspectives on the management of this disease.

Resumo Este trabalho teve como objetivo detectar evidências moleculares da presença de agentes dos gêneros Rickettsia, Borrelia, Babesia, Anaplasma e Ehrlichia transmitidos por carrapatos coletados de aves silvestres no estado do Rio de Janeiro. Aves foram capturadas e observadas cuidadosamente a procura de ectoparasitos. A detecção de DNA de hemoparasitos foi realizada por meio da reação em cadeia da polimerase (PCR). As sequências obtidas foram analisadas e sua homologia comparada aos isolados disponíveis na base de dados da plataforma GenBank. Foram capturadas 33 aves, de 20 espécies diferentes das quais 14 estavam parasitadas por Amblyomma longirostre (n = 22). Houve ausência de DNA de agentes dos gêneros Babesia, Anaplasma e Ehrlichia nas amostras avaliadas. A análise filogenética indicou que uma amostra apresentou 100% de identidade com Rickettsia bellii (KJ534309), as outras duas amostras apresentaram 100% de identidade com Rickettsia sp. cepa Aranha e Cepa AL (EU274654 e AY360216.). A amostra positiva para R. bellii também apresentou positividade para Borrelia sp. que apresentou similaridade de 91% com Borrelia turcica (KF422815). Esta é a primeira descrição de Borrelia sp. em carrapatos do gênero Amblyomma na América do Sul.

Abstract The aim of this study is to detect the presence of tick-borne agents of genera Rickettsia, Borrelia, Babesia, Ehrlichia and Anaplasma in ticks collected from native wild birds in the state of Rio de Janeiro. Birds were captured and observed carefully to find the ectoparasites. DNA detection of hemoparasites was performed by means of the polymerase chain reaction (PCR). The sequences obtained were analyzed and their homologies were compared to the available isolates in the GenBank platform database. A total of 33 birds were captured from 20 different species, of which 14 were parasitized by Amblyomma longirostre (n = 22). There was absence of DNA from agents of the genera Babesia, Anaplasma and Ehrlichia in the evaluated samples. The phylogenetic analysis indicated that one sample had 100% identity with Rickettsia bellii (KJ534309), the other two samples showed 100% identity with Rickettsia sp. Aranha strain and strain AL (EU274654 and AY360216). The positive sample for R. bellii was also demonstrated to be positive for Borrelia sp., which presented a similarity of 91% with Borrelia turcica (KF422815). This is the first description of Borrelia sp. in ticks of the genus Amblyomma in South America.

ABSTRACT The production of inoculum from arbuscular mycorrhizal fungi (AMF) at a large scale and low cost is essential for establishing methods to assist in producing pineapple plantlets with high nutritional and phytosanitary quality. However, this objective is difficult to accomplish because of the biotrophic nature of these fungi. The on-farm multiplication method for AMF inoculum presents a good alternative to supply the demand for the production of glomerospores. This study aimed to multiply and evaluate AMF inoculum originating from isolated species (including Rhizophagus clarus, Claroideoglomus etunicatum) versus native AMF from pineapple and coffee plantations multiplied by the on-farm method on the colonization in pineapple plantlets. Initially, inocula of R. clarus, C. etunicatum, and native AMF (pineapple and coffee) were multiplied by the on-farm method in Sorghum bicolor. After four months, the number of AMF spores and the percentage of viable spores at the layers of 0.00-0.05 and 0.05-0.10 m were evaluated. There were no differences in spore numbers in relation to the source of the inoculum (R. clarus, C. etunicatum, pineapple, and coffee) and evaluated layers, with an average number of 605 spores per 100 cm3 of soil. The percentage of viable spores was greater at the layer of 0.00-0.05 m (76.32 %) compared to the layer of 0.05-0.10 m (72.05 %), regardless of the inoculum source. The viability of the inoculum obtained from C. etunicatum was higher than that from the coffee crop (77.93 and 68.06 %, respectively). Subsequently, the spores were inoculated in pineapple plantlets to assess the rate of colonization. Pineapple plantlets inoculated with AMF had an average of colonization of 18 and 67.73 % after 50 and 180 days cultivation, respectively, with no significant difference being detected between treatments. Therefore, on-farm inoculum production was effective at multiplying the AMF of both isolates of R. clarus and C. etunicatum, as well as for commercial crops (pineapple and coffee), with spores having high viability. Arbuscular mycorrhizal fungi colonized pineapple plantlets independently of the inoculum utilized and favored its growth.

Resumo O Brasil é signatário da Estratégia Global para Conservação de Plantas (GSPC), que fornece diretrizes e orientações para políticas públicas nacionais já existentes. Esta estratégia visa frear a perda contínua da diversidade de plantas por meio da implementação de 16 metas baseadas em resultados estabelecidas para 2020. Segundo uma dessas metas (meta 7), 75% das espécies de plantas ameaçadas conhecidas até então devem ser preservadas in situ. Aqui, avaliamos a eficiência da atual rede brasileira de unidades de conservação (UCs) e terras indígenas (TIs) em representar todas espécies de plantas ameaçadas. Descobrimos que o número de espécies presentes em UCs e TIs depende do tipo de dado utilizado. Ao utilizar registros de ocorrência, descobrimos que 699 (33%) espécies ameaçadas de plantas encontram-se completamente fora dessas áreas, e que 1.405 espécies (67%) possuem pelo menos um registro dentro de pelo menos uma UC ou TI O número de espécies não representadas diminiuiu quando consideramos polígonos de distribuição de espécies. Neste caso, apenas 219 (10%) das espécies encontram-se supostamente desprotegidas. Embora o Brasil esteja alcançando a meta 7 da GSPC em números absolutos, o governo ainda precisa alocar recursos para manejar de forma adequada e melhorar o estado de conservação de sua flora ameaçada e para epansão a rede de UCs.

Abstract Brazil is signatory of the Global Strategy for Plant Conservation (GSPC), which provides guidelines and directions to existing national policies. This strategy aims to halt the continuing loss of plant diversity through the achievement of 16 outcome-based targets set for 2020. One of these targets (target 7) states that at least 75% of known threatened plant species should be preserved in situ. Here, we assessed the effectiveness of the Brazilian current network of protected areas (PAs) and indigenous lands (ILs) in representing all known threatened plant species. We found that the number of species represented inside PAs and ILs varied according to data type. When using occurrence records, we found that 699 (33%) threatened plant species lie completely outside PAs (and/or ILs) and that 1,405 species (67%) have at least one record inside at least one PA (and/or IL). The number of species unrepresented decreased when we considered polygons of distribution. In this case, only 219 (10%) are supposedly unprotected. Although Brazil is almost reaching GSPC Target 7 in terms of absolute numbers, the government still needs to allocate resources for properly managing and improving the conservation status of its imperiled flora and expand the network of PAs.
