Abstract The spread of SARS-CoV-2 and the distribution of cases worldwide followed no clear biogeographic, climatic, or cultural trend. Conversely, the internationally busiest cities in all countries tended to be the hardest hit, suggesting a basic, mathematically neutral pattern of the new coronavirus early dissemination. We tested whether the number of flight passengers per time and the number of international frontiers could explain the number of cases of COVID-19 worldwide by a stepwise regression. Analysis were taken by 22 May 2020, a period when one would claim that early patterns of the pandemic establishment were still detectable, despite of community transmission in various places. The number of passengers arriving in a country and the number of international borders explained significantly 49% of the variance in the distribution of the number of cases of COVID-19, and number of passengers explained significantly 14.2% of data variance for cases per million inhabitants. Ecological neutral theory may explain a considerable part of the early distribution of SARS-CoV-2 and should be taken into consideration to define preventive international actions before a next pandemic.

RESUMO A lagarta do cartucho (LCM) (Spodoptera frugiperda) é um inseto polífago que causa danos em várias culturas. Inseticidas químicos sintéticos e plantas geneticamente modificadas são os métodos mais comumente empregados para o seu controle. Entretanto, existem muitos relatos da seleção de populações resistentes, o que justifica a busca por novas moléculas para o controle de S. frugiperda. O objetivo desse trabalho foi avaliar a toxicidade do óleo essencial de capim limão (Cymbopogon flexuosus) (OECL) e seu componente majoritário, citral, para LCM. Adicionalmente, a atividade anticolinestarase do OECL e do citral foram avaliadas usando a acetilcolinestarase (AChE) de Electrophorus electricus. OECL foi tóxico para LCM, quando incorporado em dieta artificial (CL50 = 1,35 mg mL-1), nas mais altas concentrações testadas, o tempo letal mediano (TL50) foi de 18,85 h. Os componentes majoritários do OECL foram identificados por cromatografia gasosa acoplada a espectometria de massas. Citral, o composto mais abundante, foi empregado em bioensaios com LCM. A atividade inseticida do citral foi estatisticamente similar àquela do OECL, demonstrando que o citral é responsável pela atividade inseticida do OECL. A inibição da AChE foi mensurada, sendo os valores de concentração inibitória media (CI50) encontrados para o OECL e citral, 650 e 405 vezes maiores, respectivamente, do que o detectado para o controle positivo, o inseticida metomil, sugerindo seletividade para organismo não-alvo. Os resultados encontrados tornam o citral e C. flexuosus promissores para serem empregados no desenvolvimento de novos produtos para o controle de S. frugiperda.

ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda) is a polyphagous insect responsible for damage to several crops. Synthetic chemical insecticides and genetically modified plants are the most commonly used methods for FAW control. However, the selection of resistant populations has been reported in several studies, justifying the search for new molecules to be used in the control of S. frugiperda. The aim of the present study was to evaluate the toxicity of lemongrass (Cymbopogon flexuosus) essential oil (LEO) and its major component (citral) in relation to FAW. Additionally, the anticholinesterase activity of LEO and citral was evaluated using acetylcholinesterase (AChE) from Electrophorus electricus. The LEO was toxic to FAW when added to an artificial diet (LC50 = 1.35 mg mL-1) at the highest concentrations tested, and the median lethal time (LT50) was 18.85 h. Major components of LEO were identified by gas chromatography-mass spectrometry, and citral, the most abundant component, was used in FAW bioassays. The insecticidal activity of citral was statistically similar to that of LEO, demonstrating that citral was responsible for the insecticidal activity of LEO. Inhibition of AChE was measured, and the mean inhibitory concentration (IC50) values for LEO and citral were 650- and 405-fold higher, respectively, than that verified for the positive control (methomyl insecticide), suggesting selectivity for non-target organisms. Based on these results, citral and C. flexuosus have the potential to be applied in the development of new products for the control of S. frugiperda.

ABSTRACT The metabolism of ethanol occurs mainly in the liver, promoting increase of reactive oxygen species and nitrogen, leading to redox imbalance. Therefore, antioxidants can be seen as an alternative to reestablish the oxidizing/reducing equilibrium. The aim of this study was to evaluate the antioxidant and hepatoprotective effect of aqueous extract of Baccharis trimera (Less.) DC., Asteraceae, in a model of hepatotoxicity induced by ethanol. The extract was characterized and in vitro tests were conducted in HepG2 cells. It was evaluated the cells viability exposed to aqueous extract for 24 h, ability to scavenging the radical DPPH, besides the production of reactive oxygen species and nitric oxide, and the influence on the transcriptional activity of transcription factor Nrf2 (12 and 24 h) after exposure to 200 mM ethanol. The results showed that aqueous extract was non-cytotoxic in any concentration tested; moreover, it was observed a decrease in ROS and NO production, also promoting the transcriptional activity of Nrf2. In vivo, we pretreatment male rats Fisher with 600 mg/kg of aqueous extract and 1 h later 5 ml/kg of absolute ethanol was administrated. After two days of treatment, the animals were euthanized and lipid profile, hepatic and renal functions, antioxidant status and oxidative damage were evaluated. The treatment with extract improved liver function and lipid profile, reflecting the reduction of lipid microvesicules in the liver. It also promoted an increase of glutathione peroxidase activity, decrease of oxidative damage and MMP-2 activity. These results, analyzed together, suggest the hepatoprotective effect of B. trimera aqueous extract.

Resumo Objetivos Avaliar incidência de tuberculose e triagem para tuberculose latente em brasileiros com artrite reumatoide em uso de agentes biológicos na prática clinica. Pacientes e métodos Estudo de coorte com dados do Registro Brasileiro de Monitoração de Terapias Biológicas (BiobadaBrasil), de 01/2009 a 05/2013, abrangeu 1.552 tratamentos, 415 somente com drogas modificadoras do curso da doença (MMCDs) sintéticas, 942 MMCDs sintéticas em associação com anti-TNF (etanercepte, infliximabe, adalimumabe) e 195 MMCDs sintéticas em associação com outros biológicos (abatacepte, rituximabe e tocilizumabe). Avaliaram-se ocorrência de tuberculose, tempo de exposição às drogas e triagem para TB. Análise estatística: teste t não pareado e teste de Fisher bicaudal; p < 0,05. Resultados O tempo de exposição dos controles foi de 981 pacientes-ano, do grupo de anti-TNF foi de 1.744 pacientes-ano (adalimumabe = 676, infliximabe = 547 e etanercepte = 521 pacientes-ano) e o de outros biológicos de 336 pacientes-ano. A incidência de TB foi de 1,01/1.000 pacientes-ano nos controles e de 2,87 pacientes-ano nos usuários de anti-TNF (adalimumabe = 4,43/1.000 pacientes-ano; etanercepte = 1,92/1.000 pacientes-ano e infliximabe = 1,82/1.000 pacientes-ano). Não houve casos de tuberculose no grupo de outros biológicos. O tempo médio de exposição até a ocorrência de tuberculose foi de 27(11) meses para o grupo anti-TNF. Conclusões A incidência de tuberculose foi maior nos usuários de MMCDs sintéticas e anti-TNF do que nos usuários de MMCDs sintéticas e de MMCDs sintéticas e biológicos não anti-TNF, e também mais tardia, sugerindo infecção durante o tratamento, e não falha na triagem.

Abstract Objectives To assess the incidence of tuberculosis and to screen for latent tuberculosis infection among Brazilians with rheumatoid arthritis using biologics in clinical practice. Patients and methods This cohort study used data from the Brazilian Registry of Biological Therapies in Rheumatic Diseases (Registro Brasileiro de Monitoração de Terapias Biológicas - BiobadaBrasil), from 01/2009 to 05/2013, encompassing 1552 treatments, including 415 with only synthetic disease-modifying anti-rheumatic drugs, 942 synthetic DMARDs combined with anti-tumor necrosis factor (etanercept, infliximab, adalimumab) and 195 synthetic DMARDs combined with other biologics (abatacept, rituximab and tocilizumab). The occurrence of tuberculosis and the drug exposure time were assessed, and screening for tuberculosis was performed. Statistical analysis: Unpaired t-test and Fisher's two-tailed test; p < 0.05. Results The exposure times were 981 patient-years in the controls, 1744 patient-years in the anti-TNF group (adalimumab = 676, infliximab = 547 and etanercept = 521 patient-years) and 336 patient-years in the other biologics group. The incidence rates of tuberculosis were 1.01/1000 patient-years in the controls and 2.87 patient-years among anti-TNF users (adalimumab = 4.43/1000 patient-years; etanercept = 1.92/1000 patient-years and infliximab = 1.82/1000 patient-years). No cases of tuberculosis occurred in the other biologics group. The mean drug exposure time until the occurrence of tuberculosis was 27(11) months for the anti-TNF group. Conclusions The incidence of tuberculosis was higher among users of synthetic DMARDs and anti-TNF than among users of synthetic DMARDs and synthetic DMARDs and non-anti-TNF biologics and also occurred later, suggesting infection during treatment and no screening failure.

Objetivo: a doença renal crônica (DRC) é um problema crescente no mundo em razão do crescimento exponencial do diabetes mellitus, da hipertensão e de outros fatores de risco. O objetivo deste estudo é investigar alterações urinárias e fatores de risco para doença renal na população geral. Métodos: este estudo foi realizado a partir de dados coletados durante as campanhas anuais do Dia Mundial do Rim, em Fortaleza, Ceará, Brasil, entre 2009 e 2012. A população buscou atendimento espontaneamente nos stands montados em locais de alto tráfego de pessoas. Resultados: entre 2.637 indivíduos entrevistados, a média de idade foi de 50,7±15,7 anos, sendo 53% do gênero masculino. Os principais fatores de risco encontrados foram sedentarismo (60,7%), obesidade (22,7%) e tabagismo (19,8%). Pressão arterial (PA) > 140x90 mmHg foi encontrada em 877 casos (33%). Aumento da PA foi encontrado pela primeira vez em 527 casos (19,9%). Doenças cardiovasculares foram relatadas por 228 indivíduos (8,6%). Diabetes foi relatado por 343 indivíduos (13%). Glicemia capilar > 200 mg/dL foi encontrada em 127 casos (4,8%) e > 200 mg/dL pela primeira vez em 30 (1,13%). O exame de urina foi realizado por 1.151 pessoas, sendo encontrada proteinúria em 269 casos (23,3%). Proteinúria foi mais frequente em pessoas com hipertensão (77,3% vs. 55,8%, p = 0,0001), diabetes mellitus (22,7% vs. 15,2%, p = 0,005) e em idosos (42,1% vs. 30,7%, p = 0,0007). Conclusão: fatores de risco para DRC são frequentes na população geral. Muitos indivíduos tinham hipertensão e diabetes e não sabiam disso. É importante a realização de ações como o Dia Mundial do Rim com o objetivo de detectar precocemente potenciais candidatos à DRC.

Objective: chronic kidney disease (CKD) is an increasing common problem in the world due to the exponential growth of diabetes mellitus, hypertension and other risk factors. The aim of this study is to investigate urinary abnormalities and risk factors for kidney disease in the general population. Methods: this study was performed from data collected during the annual World Kidney Day (WKD) campaigns, in Fortaleza, Ceará, Brazil, between 2009 and 2012. The population sought assistance spontaneously in stands placed in high people-traffic areas. Results: among 2,637 individuals interviewed, the mean age was 50.7±15.7 years and 53% were male. The main risk factors found were sedentarism (60.7%), obesity (22.7%) and smoking (19.8%). Blood pressure (BP) > 140x90 mmHg was found in 877 (33%). Increased BP was found for the first time in 527 cases (19.9%). Cardiovascular diseases were reported in 228 (8.6%). Diabetes was related by 343 (13%). Capillary blood glucose > 200 mg/dL was found in 127 (4.8%) and it was > 200 mg/dL for the first time in 30 (1.13%). Urinalysis was performed in 1,151 people and found proteinuria in 269 (23.3%). Proteinuria was most frequent in hypertension people (77.3% vs. 55.8%, p=0.0001), diabetes mellitus (22.7% vs. 15.2%, p=0.005) and elderly (42.1% vs. 30.7%, p=0.0007). Conclusion: risk factors for CKD are frequent in the general population. Many individuals had hypertension and diabetes and did not know this. It is important to regularly perform actions like WKD in order to early detect potential candidates for CKD.

Conduziu-se este trabalho, com o objetivo de quantificar taninos condensados presentes nas cascas do caule de Ochroma pyramidalis (Bombacaceae), Schinus terebinthifolius (Anacardiaceae), Enterolobium contortisiliquum (Fabaceae) e Peltophorum dubium (Fabaceae) e verificar o efeito de frações tânicas dessas espécies sobre parâmetros biológicos e nutricionais de S. frugiperda. A partir das cascas das espécies vegetais se prepararam extratos, dos quais alíquotas foram tomadas para a quantificação dos taninos. Em seguida, os extratos foram submetidos a fracionamento para a obtenção das frações tânicas, que foram incorporadas à dieta artificial e oferecidas para lagartas de S. frugiperda. Todas as espécies vegetais estudadas apresentaram taninos condensados, sendo que S. terebinthifolius apresentou menor quantidade desses compostos. A fração tânica de P. dubium causou redução no peso das lagartas e pupas, diminuição na sobrevivência de S. frugiperda durante as fases larval e pupal, e acarretou menor consumo alimentar, além de prolongar a duração das fases imaturas desse inseto. O tratamento com S. terebinthifolius causou redução na percentagem de sobrevivência, durante a fase de pupa. Pupas provenientes de lagartas que receberam tratamento com a fração de E. contortisiliquum tiveram aumento no seu período de desenvolvimento. Lagartas alimentadas com a fração proveniente de P. dubium apresentaram a menor taxa de crescimento relativo (RGR), menor eficiência de conversão do alimento digerido (ECD) e maior custo metabólico (CM). A digestibilidade aproximada (AD) foi maior para os tratamentos com as frações tânicas de P. dubium e S. terebinthifolius.

The objective of this study was to quantify condensed tannins present in the stem bark of Ochroma pyramidalis (Bombacaceae), Schinus terebinthifolius (Anacardiaceae), Enterolobium contortisiliquum (Fabaceae) and Peltophorum dubium (Fabaceae) and to verify the effect of tannic fractions of these species on biological and nutritional parameters of S. frugiperda. Extracts were prepared from the barks of the plant species and aliquots were taken from them to quantify the tannins. The extracts were then submitted to fractionation to obtain the tannic fractions, which ones were incorporated into an artificial diet and offered to the larvae of S. frugiperda. All the studied species showed condensed tannins, and S. terebinthifolius showed the lowest amount of these compounds. The tannin fraction of P. dubium caused a reduction in the weight of larvae and pupae, decreased the survival of S. frugiperda during the larval and pupal stages and led to a reduction of intake, beyond to extend the duration of immature stages of this insect. The treatment with S. terebinthifolius caused a reduction in the survival percentage during the pupal stage. Pupae from larvae that received the treatment with the fraction of E. contortisiliquum had an increase in its development period stage. Larvae fed with the fraction from P. dubium showed the lowest relative growth rate (RGR), lower efficiency of conversion of ingested food (ECI) and a higher metabolic cost (CM). The approximate digestibility (AD) was higher for the treatments with tannic fractions of P. dubium and S. terebinthifolius.

Abstract: En | Text: En | PDF: En

The knowledge of the slug flow characteristics is very important when designing pipelines and process equipment. When the intermittences typical in slug flow occurs, the fluctuations of the flow variables bring additional concern to the designer. Focusing on this subject the present work discloses the experimental data on slug flow characteristics occurring in a large-size, large-scale facility. The results were compared with data provided by mechanistic slug flow models in order to verify their reliability when modelling actual flow conditions. Experiments were done with natural gas and oil or water as the liquid phase. To compute the frequency and velocity of the slug cell and to calculate the length of the elongated bubble and liquid slug one used two pressure transducers measuring the pressure drop across the pipe diameter at different axial locations. A third pressure transducer measured the pressure drop between two axial location 200 m apart. The experimental data were compared with results of Camargo's1 algorithm (1991, 1993), which uses the basics of Dukler & Hubbard's (1975) slug flow model, and those calculated by the transient two-phase flow simulator OLGA.

A reoperação de próteses valvulares tem sido realizada, com freqüência cada vez maior, nos vários Serviços de cirurgia cardíaca. Os detalhes do tratamento, a indicação e a técnica operatória melhoraram os resultados. No período de janeiro de 1984 a junho de 1986, no Instituto do Coração, foram submetidos a retroca valvular 145 pacientes, num total de 157 próteses, e 4 trocas da bola de válvula de Starr-Edwards. Em posição mitral, 6 pacientes foram submetidos a terceira troca valvular, sem óbito imediato. A insuficiência valvular e a calcificação do tecido biológico de dura-máter foram as principais causas de indicação da reoperação. Quarenta e um pacientes apresentavam roturas e 19 pacientes, calcificação de bioprótese em posição mitral; em posição aórtica, 32 pacientes tinham rotura e 12, calcificação de bioprótese. Quanto à prótese implantada, foram utilizadas principalmente as biopróteses, sendo 63 porcinas e 35 de pericárdio bovino. A mortalidade imediata global foi de 8,3% (12 pacientes), sendo a principal causa de óbito o baixo débito cardíaco. As principais complicações imediats foram: baixo débito cardíaco, arritmias e sangramento. Noventa por cento dos pacientes encontravam-se em classe funcional (NYHA) III e IV no pré-operatório, evoluindo para as classes funcionais I e II em 89% das trocas aórticas de 82% das trocas mitrais. A curva atuarial de sobrevida.em 5 semestres, foi, para a posição mitral, de 85,7% e, para a aórtica, de 91,3%. Os autores concluem que os cuidados de técnica, a proteção miocárdica e o tipo de prótese utilizada foram os responsáveis pelos resultados bastante satisfatórios.

Replacement of valvular prosthesis is an increasingly frequent procedure in heart surgery. Better results are attained with the observation of correct indication and improved surgical technique. In the period of January 1984 to June 1986, 145 patients were submitted to prosthesis replacement, at our Institution. These patients received a total of 157 prostheses and 4 had their Starr-Edwards valve ball replaced due to ball variance. Six patients were submitted to a third valvular replacement in the mitral position, withouth deaths. Nine patients had a third valvular replacement in the aortic position with 1 death in the immediate postoperative period. Rupture or calcification of the dura mater leaflets were the main reason for the indication of prosthetic replacement. In the mitral position 41 patients presented rupture of the leaflets and 19 showed calcification. In the aortic position 32 bioprostheses underwent rupture and 12, calcification. Bio-prostheses were utilized in the majority of cases of replace the dysfunctioning prostheses. Porcine bioprostheses were implanted in 63 cases and bovine pericardial bioprostheses, in 35. Immediate mortality was 8.3% (12 patients); low cardiac output was the main cause of death. The most frequent immediate complications were low cardiac output, arrhythmias and bleeding. In the preoperative period 90% of the patients were in functional classes III and IV (NYHA). After the replacement, 89% of the aortics and 82% of the mitral were in functional classes I an II.

Os autores fizeram um estudo da associação hexaidmto de piperazina e tiabendazol em 41 indivíduos parasitados por aneilostomideos, Áscaris e/ou Strongyloides . Usando um esquema de duas doses diárias em três dias seguidos (5ml/ 15kg) encontraram 26 negativados (63,4% de curas). Considerando cada parasito isoladamente obtiveram: para Ascaris lumbricoides 16 curados em 18 tratados (90%); para Strongyloides stercoralis, 30 sucessos em 31 casos observados (97%) e para Aneilostomideos, 27 curas em 41 tratados (65$%). Salientam o valor terapêutico dessa associação medicamentosa não só para tratamento individual de poliparasitaâos como na profilaxia das helmintíases humanas.
