ABSTRACT This study aimed to evaluate the addition of different concentrations of IGF-I and insulin to egg yolk-based extender to improve bovine semen cryopreservation. Two experiments were developed to evaluate the effects of the additives in two commercial extenders, Botubov® (Experiment 1) and Triladyl® (Experiment 2), both with the same design. Three ejaculates from four bulls (n = 12) were used. Each ejaculate was divided into seven equal fractions for dilution (60x106 spermatozoa/mL) in the following treatments: CON: extender only; IGF100: IGF-I 100ng/mL; IGF200: IGF-I 200ng/mL; INS150: insulin 150µUI/mL; INS200: insulin 200µUI/mL; ASS1: IGF-I 100ng/mL + insulin 150µUI/mL; ASS2: IGF-I 200ng/mL + insulin 200µUI/mL. Semen was cryopreserved by an automated system. Post-thawed sperm were evaluated regarding motility by CASA (Computer-assisted sperm analysis), and membranes by fluorescent probes (H342, PI, FITC-PSA and JC-1). For Botubov® extender, INS150 was more efficient in preserving total and progressive motility, VCL, BCF, plasma and mitochondrial membranes. A similar response was seen when insulin was added to the Triladyl® extender, INS150 was more efficient in preserving sperm motility, plasma membrane integrity and mitochondrial potential. Thus, the addition of insulin 150µUI/mL, regardless of the composition of the extender, contributes to better preserving bovine sperm from the cryopreservation effects.
RESUMO Este estudo teve o objetivo de avaliar a adição de diferentes concentrações de IGF-I e insulina a diluidores, à base de gema de ovo, para melhorar a criopreservação do sêmen bovino. Dois experimentos foram desenvolvidos para avaliar os efeitos dos aditivos em dois diluidores comerciais: Botubov® (Experimento 1) e Triladyl® (Experimento 2), ambos com o mesmo delineamento. Foram utilizados três ejaculados de quatro touros (n=12). Cada ejaculado foi dividido em sete frações para diluição (60x106espermatozoides/mL), nos seguintes tratamentos: CON: somente diluidor; IGF100: 100ng/mL de IGF-I; IGF200: 200ng/mL de IGF-I; INS150: 150µUI/mL de insulina; INS200: 200µUI/mL de insulina; ASS1: 100ng/mL de IGF-I + 150µUI/mL de insulina; ASS2: 200ng/mL de IGF-I + 200µUI/mL de insulina. O sêmen foi criopreservado por sistema automatizado. Após a criopreservação, o sêmen foi avaliado quanto à motilidade espermática por CASA e quanto às membranas espermáticas (plasmática, acrossomal e mitocondrial) por sondas fluorescentes (H342, PI, FITC-PSA e JC-1). Para o diluidor Botubov®, INS150 foi mais eficiente em preservar motilidades total e progressiva, VCL, BCF, integridade da membrana plasmática e potencial mitocondrial. Resposta semelhante foi observada quando a insulina foi adicionada ao diluidor Triladyl®, INS150 foi mais eficiente na preservação da motilidade, integridade das membranas e potencial mitocondrial quando comparado aos demais grupos. Assim, a adição de 150µUI/mL de insulina aos diluidores, independentemente da composição, contribui para melhor criopreservação dos espermatozoides bovinos.

We aimed to study the mechanism behind worse coronavirus disease-19 (COVID-19) outcomes in men and whether the differences between sexes regarding mortality as well as disease severity are influenced by sex hormones. To do so, we used age as a covariate in the meta-regression and subgroup analyses. This was a systematic search and meta-analysis of observational cohorts reporting COVID-19 outcomes. The PubMed (Medline) and Cochrane Library databases were searched. The primary outcome was COVID-19-associated mortality and the secondary outcome was COVID-19 severity. The study was registered at PROSPERO: 42020182924. For mortality, men had a relative risk of 1.36 (95%CI: 1.17 to 1.59; I2 63%, P for heterogeneity <0.01) compared to women. Age was not a significant covariate in meta-analysis heterogeneity (P=0.393) or subgroup analysis. For disease severity, being male was associated with a relative risk of 1.29 (95%CI: 1.19 to 1.40; I2 48%, P for heterogeneity <0.01) compared to the relative risk of women. Again, age did not influence the outcomes of the meta-regression (P=0.914) or subgroup analysis. Men had a higher risk of COVID-19 mortality and severity regardless of age, decreasing the odds of hormonal influences in the described outcomes.

Convalescent plasma therapy has shown controversial results in coronavirus disease-19 (COVID-19) patients. We performed a non-randomized case-control study with contemporaneous controls in a hospital in southern Brazil. Patients were selected for treatment with convalescent plasma by medical decision and compared with patients who did not receive plasma and were hospitalized due to COVID-19 at the same time. The outcomes of interest were intensive care unit (ICU) admission and in-hospital death. Patients that received convalescent plasma had lower in-hospital mortality than patients that did not receive plasma (relative risk (RR) 0.48; 95% confidence interval (CI) 0.29 to 0.79) and these results were consistent after changing the subset of control patients. There were no differences regarding ICU admission between groups (RR=0.80; 95%CI: 0.47 to 1.35). In this study, patients that received convalescent plasma for COVID-19 had lower in-hospital mortality, but this finding requires further confirmation given the retrospective nature of the study.

RESUMO No presente trabalho, foi avaliado o efeito imunomodulador de diferentes doses de talidomida em macrófagos associados ao tumor (TAMs), em um modelo murino de câncer de mama. Camundongos foram inoculados com células 4T1, na região do flanco esquerdo, e tratados com talidomida, uma vez ao dia, nas doses de 50, 100 e 150mg/k, por massa corporal, do quinto dia ao 28º dia de inoculação tumoral. Os tumores foram medidos, o índice de proliferação celular e a contagem de TAMs foram avaliados nos tumores primários e nos pulmões com metástases. Além disso, a taxa de metástases pulmonares também foi avaliada. A talidomida na dose de 150mg/kg diminuiu significativamente o crescimento tumoral, o índice de proliferação celular e a infiltração de TAMs nos tumores primários. Por outro lado, maior número de TAMs e menor índice de proliferação celular foram observados nos pulmões metastáticos, em camundongos tratados com 150mg/kg de talidomida. Ademais, a talidomida na dose de 150mg/kg diminuiu significativamente os nódulos metastáticos nos pulmões. Os resultados demonstraram que o tratamento com talidomida diminuiu o crescimento tumoral e as metástases pulmonares em camundongos, associado com diferentes efeitos na infiltração de TAMs nesses locais.
ABSTRACT The present work evaluated the immunomodulatory effect of thalidomide (Thal) at different doses on tumor-associated macrophages (TAMs) using a mouse model of human breast cancer. Mice were inoculated with 4T1 cells in the left flank and treated with Thal once a day at concentrations of 50, 100, and 150mg/kg body weight from the 5th day until the 28th day of tumor inoculation. The tumors were sized, proliferation index and TAMs count were evaluated in primary tumors and metastatic lungs. In addition, the metastasis rate was evaluated in the lungs. Thal at 150mg/kg significantly decreased tumor growth, proliferation index, and TAMs infiltration in primary tumors. Conversely, a higher number of TAMs and lower proliferation index were observed in metastatic lungs in mice treated with 150mg/kg of Thal. Furthermore, Thal at 150mg/kg significantly decreased the metastatic nodules in the lungs. Our findings demonstrated that Thal treatment considerably decreased the primary tumor and lung metastasis in mice associated with different TAM infiltration effects in these sites.

RESUMO: Escherichia coli Enteropatogênica (EPEC) e Shigatoxigênica (STEC) estão entres os principais patotipos encontrados em aves e produtos avícolas que são capazes de causar doença entérica no homem. A colistina tem sido preconizada como droga de escolha para o tratamento de doenças causadas por bactérias Gram-negativas multirresistentes em humanos. O gene mcr-1 foi o primeiro gene plasmidial a ser descrito como responsável pela resistência a colistina e tem sido descrito em aves e produtos avícolas. Este estudo tem como objetivo a detecção do gene mcr-1 em estirpes de E. coli enteropatogênicas a fim de avaliar a resistência a colistina em frangos de corte. O material foi obtido a partir de 240 amostras cloacais e 60 carcaças de frango de corte. As estirpes foram isoladas pelo método bacteriológico convencional e os genes de virulência, que caracterizam as estirpes enteropatogênicas, e resistência foram detectados pela reação em cadeia pela polimerase (PCR). Das 213 estirpes de E. coli isoladas, 57 (26,76%) foram caracterizadas como EPEC atípica e 35 (16,43%) como STEC. O gene mcr-1 foi encontrado em 3,5% (2/57) das estirpes EPEC e 5,7% (2/35) das estirpes STEC. Neste estudo foi possível confirmar que o gene de resistência mcr-1 já está em circulação nos lotes de frango de corte estudados e pode estar associado às estirpes patogênicas.
ABSTRACT: Enteropathogenic Escherichia coli (EPEC) and Shigatoxigenic E. coli (STEC) strains are among the major pathotypes found in poultry and their products, which are capable of causing human enteric infections. Colistin has been claimed the drug of choice against diseases caused by multidrug-resistant Gram-negative bacteria (MDRGN) in humans. The mcr-1 gene was the first plasmidial gene that has been described to be responsible for colistin resistance and has also been detected in birds and poultry products. Our study aimed to detect the mcr-1 gene in enteropathogenic strains of E. coli in order to evaluate the resistance to colistin in broilers. The material was obtained from 240 cloacal samples and 60 broiler carcasses. The strains were isolated by the conventional bacteriological method and by the virulence genes, which characterize the enteropathogenic strains and resistance, and the samples were detected by polymerase chain reaction (PCR). Of the 213 isolated strains of E. coli, 57 (26.76%) were characterized as atypical EPEC and 35 (16.43%) as STEC. The mcr-1 gene was found in 3.5% (2/57) of the EPEC strains and 5.7% (2/35) of the STEC strains. In this study, it was possible to confirm that the mcr-1 resistance gene is already circulating in the broiler flocks studied and may be associated with the pathogenic strains.

ABSTRACT Erythraline is the major alkaloid produced by Erythrina verna Vell., Fabaceae, a plant used in folk medicine and phytotherapeutic products to treat anxiety and sleep disorders. This study aimed to investigate the pharmacokinetic parameters of erythraline after intravenous administration in rats. For the analysis of erythraline in rat plasma, a method was developed and validated using UHPLC-MS/MS. Pharmacokinetic parameters were estimated by non-compartmental analysis. The metabolite 8-oxo-erythraline observed in previous biomimetic model studies was monitored during in vivo experiments. The quantification limit was 5 ng/ml within a linear range of 5-2000 ng/ml. After an intravenous dose of 1 mg/kg, the following pharmacokinetic parameters were observed: elimination half-life of 44.2 min; total clearance of 42.1 ml/min/kg and volume of distribution of 2085 ml/kg. In summary, a precise, accurate and selective UHPLC-MS/MS method was developed and successfully applied to investigate the pharmacokinetics of erythraline in rats. The metabolite 8-oxo-erythraline was observed in rat plasma after 20 min of erythraline administration.

RESUMO Recentes pesquisas relatam a importância da preservação de plantas do semiárido brasileiro. Neste contexto, a literatura científica tem relatado diferentes estudos farmacológicos com extratos vegetais com potencial antifúngico proveniente de espécies florestais que podem contribuir como estratégia de controle e gerenciamento na transmissão de fitopatógenos. No presente estudo o objetivo foi avaliar o efeito de tratamentos biotecnológicos no controle da transmissibilidade de Colletotrichum sp. em sementes de S. obtusifolium. Neste estudo foram utilizadas 100 sementes submetidas aos seguintes tratamentos preventivos: fungicida Captan®, extrato de Caesalpinia ferrea Mart. Ex. Tul. e controle biológico com Trichoderma spp. O controle biológico com Trichoderma spp. e o alternativo com extrato de C. ferrea proporcionam maior proteção às sementes e plântulas S. obtusifolium quanto a transmissibilidade do Colletotrichum sp. O tratamento à base de extrato vegetal foi o mais eficiente para este fim, apenas em sementes de maior tamanho, por não interferir na porcentagem e velocidade de germinação. Portanto, faz-se necessário à realização de outros trabalhos com Trichoderma spp. e extrato de C. ferrea para testar doses diferentes desses produtos.
ABSTRACT Recent research reports the importance of preserving plants in Brazilian semiarid regions, in this context, the scientific literature has reported different pharmacological studies from plant extracts with an antifungal potential, coming from forest species that can contribute as a control and management strategy in the transmission of phytopathogens. This study aimed to evaluate the effect of biotech treatments in controlling the transmission of Colletotrichum sp. in seeds of S. obtusifolium. In this study, 100 seeds were subjected to the following preventive treatments: fungicide Captan®, extract of Caesalpinia ferrea Mart. Ex. Tul., and biological control with Trichoderma spp. The biological control with Trichoderma spp. and the alternative control using C. ferrea extract provided a greater protection to seeds and seedlings of S. obtusifolium facing the transmissibility of Colletotrichum sp.The treatment based on plant extract is more efficient for this purpose only in large seeds and does not interfere on the germination percentage and speed. Therefore it is necessary to perform other studies with Trichoderma spp. and C. ferrea extract to test different doses of these products.

Resumo Objetivo: Analisar as variáveis demográficas e clínicas associadas à diminuição da qualidade de vida em uma grande coorte brasileira de pacientes com espondiloartrite (EpA). Métodos: Foi aplicado um protocolo de pesquisa único a 1.465 pacientes brasileiros classificados como tendo EpA de acordo com os critérios do European Spondyloarthropaties Study Group (ESSG), atendidos em 29 centros de referência em reumatologia do Brasil. Foram registradas as variáveis clínicas e demográficas. A qualidade de vida foi analisada por meio do questionário Ankylosing Spondylitis Quality of Life (ASQoL). Resultados: A pontuação média do ASQoL foi de 7,74 (+ 5,39). Ao analisar doenças específicas no grupo de EpA, as pontuações do ASQoL não apresentaram diferença estatisticamente significativa. Os dados demográficos mostraram piores escores de ASQoL associados ao gênero feminino (p = 0,014) e etnia negra (p < 0,001). Quanto aos sintomas clínicos, a dor na região glútea (p = 0,032), a dor cervical (p < 0,001) e a dor no quadril (p = 0,001), estiveram estatisticamente associadas a piores escores no ASQoL. O uso contínuo de fármacos anti-inflamatórios não esteroides (p < 0,001) e agentes biológicos (p = 0,044) esteve associado a escores mais elevados de ASQoL, enquanto outros medicamentos não interferiram nos escores do ASQoL. Conclusão: Nesta grande série de pacientes com EpA, o sexo feminino e a etnia negra, bem como sintomas predominantemente axiais, estiveram associados a uma qualidade de vida reduzida.
Abstract Objective: To analyze quality of life and demographic and clinical variables associated to its impairment in a large Brazilian cohort of patients with spondyloarthritis (SpA). Methods: A common protocol of investigation was applied to 1465 Brazilian patients classified as SpA according to the European Spondyloarthropaties Study Group (ESSG) criteria, attended at 29 reference centers for Rheumatology in Brazil. Clinical and demographic variables were recorded. Quality of life was analyzed through the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire. Results: The mean ASQoL score was 7.74 (± 5.39). When analyzing the specific diseases in the SpA group, the ASQoL scores did not present statistical significance. Demographic data showed worse scores of ASQoL associated with female gender (p = 0.014) and African-Brazilian ethnicity (p < 0.001). Regarding clinical symptoms, buttock pain (p = 0.032), cervical pain (p < 0.001) and hip pain (p = 0.001), were statistically associated with worse scores of ASQoL. Continuous use of nonsteroidal anti-inflammatory drugs (p < 0.001) and biologic agents (p = 0.044) were associated with higher scores of ASQoL, while the other medications did not interfere with the ASQoL scores. Conclusion: In this large series of patients with SpA, female gender and African-Brazilian ethnicity, as well as predominant axial symptoms, were associated with impaired quality of life.

Objetivo Avaliar os resultados da aplicação do Índice de Atividade de Doença da Espondilite Anquilosante de Bath (BASDAI) numa série de pacientes brasileiros com EpA e estabelecer suas correlações com as variáveis específicas do grupo. Métodos Um protocolo comum de investigação foi prospectivamente aplicado em 1.492 pacientes brasileiros classificados como EpA pelos critérios do Grupo Europeu de Estudo das Espondiloartropatias (ESSG), acompanhados em 29 centros de referência em reumatologia no Brasil. Variáveis clínicas, demográficas e índices de doença foram colhidos. Os valores totais do BASDAI foram comparados com a presença das diferentes variáveis. Resultados O valor médio do BASDAI foi de 4,20 ± 2,38. Os escores médios do BASDAI foram mais elevados nos pacientes com forma clínica combinada, comparado às formas axiais e periféricas isoladas, nos pacientes do sexo feminino e nos sedentários. Com relação ao componente axial, valores mais altos do BASDAI estiveram significativamente associados à lombalgia inflamatória, à dor alternante em nádegas, à dor cervical e ao acometimento de coxofemorais. Houve associação estatística entre os valores do BASDAI e o comprometimento periférico, relacionado ao número de articulações inflamadas, tanto dos membros inferiores quanto dos membros superiores, e às entesites. A positividade do HLA-B27 e a presença de manifestações extra-articulares não estiveram correlacionadas com os valores médios do BASDAI. Valores mais baixos do BASDAI estiveram associados ao uso de agentes biológicos (p < 0,001). Conclusão Nesta série heterogênea de pacientes brasileiros com EpA, o BASDAI conseguiu demonstrar “atividade de doença” tanto nos pacientes com acometimento axial quanto naqueles com envolvimento periférico.
Objective To analyze the results of the application of the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in a large series of Brazilian patients with the diagnosis of SpA and establish its correlations with specific variables into the group. Methods A common protocol of investigation was prospectively applied to 1492 Brazilian patients classified as SpA according to the European Spondyoarthropathies Study Group (ESSG), attended at 29 referral centers of Rheumatology in Brazil. Clinical and demographic variables, and disease indices (BASDAI, Basfi, Basri, Mases, ASQol) were applied. The total values of BASDAI were compared to the presence of the different variables. Results The mean score of BASDAI was 4.20 ± 2.38. The mean scores of BASDAI were higher in patients with the combined (axial + peripheral + entheseal) (4.54 ± 2.38) clinical presentation, compared to the pure axial (3.78 ± 2.27) or pure peripheral (4.00 ± 2.38) clinical presentations (P < 0.001). BASDAI also presented higher scores associated with the female gender (P < 0.001) and patients who did not practice exercises (P < 0.001). Regarding the axial component, higher values of BASDAI were significantly associated with inflammatory low back pain (P < 0.049), alternating buttock pain (P < 0.001), cervical pain (P < 0.001) and hip involvement (P < 0.001). There was also statistical association between BASDAI scores and the peripheral involvement, related to the lower (P = 0.004) and upper limbs (P = 0.025). The presence of enthesitis was also associated to higher scores of BASDAI (P = 0.040). Positive HLA-B27 and the presence of cutaneous psoriasis, inflammatory bowel disease, uveitis and urethritis were not correlated with the mean scores of BASDAI. Lower scores of BASDAI were associated with the use of biologic agents (P < 0.001). Conclusion In this heterogeneous Brazilian series of SpA patients, BASDAI was able to demonstrate “disease activity” in patients with axial as well as peripheral disease.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.
Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

A composição de ácidos graxos da dieta pode influenciar o desempenho produtivo e o sistema imune de frangos de corte. O objetivo deste estudo foi avaliar o efeito do consumo de óleos ricos em ácidos graxos poli-insaturados ômega-6 (PUFAs n-6) e ômega-3 (PUFAs n-3) sobre o desempenho e a resposta imunológica de frangos de corte frente a um desafio antigênico. Foram comparadas dietas formuladas com 7% de óleo de soja (OS), linhaça (OL) ou sardinha (OP), fornecidas a 240 frangos da linhagem Cobb, divididos em 24 grupos de 10 aves cada, num arranjo experimental 3x2 (3 tipos de óleo e aves vacinadas ou não vacinadas) e 4 repetições. O óleo de soja é rico em ácido linoleico, um PUFA n-6, o óleo de linhaça é fonte de ácido alfa-linolênico, um PUFA n-3, e o óleo de sardinha, de outros PUFAs n-3, como os ácidos eicosapentaenoico e docosahexaenoico. O consumo de ração, o ganho de peso e a conversão alimentar foram avaliados aos 21, 35 e 42 dias. Aos 7 e aos 21 dias de idade, metade das aves recebeu vacina contra doença de Newcastle. Quinze dias após a imunização, avaliou-se a produção de anticorpos pelo método de ELISA, expressa pela densidade óptica a 450 nm (D.O. 450nm). Apenas as aves alimentadas com ração contendo OS apresentaram maior imunidade humoral (P<0,05) após a vacinação. A resposta linfoproliferativa das aves, que expressa a imunidade celular, foi maior entre as aves vacinadas, em comparação às aves não vacinadas (P<0,05), independentemente do óleo utilizado. A fonte de óleo da ração ou a vacinação não influenciaram o ganho de peso das aves (P>0,05). Entre as aves que receberam dieta com OS, as aves vacinadas apresentaram pior conversão alimentar (P<0,05). Nos grupos que consumiram ração com OL ou OP, a vacinação não influenciou a conversão alimentar (P>0,05), considerando todo o período experimental. A utilização de óleo rico em PUFA n-6 na dieta de frangos de corte aumentou a resposta humoral, mas não influenciou a resposta celular frente a um desafio antigênico.
The fatty acid composition in the diet can affect the productive performance and the immune system of broiler chickens. The objective of this study was to evaluate the effect of the consumption of oils rich in omega-6 (n-6 PUFA) and omega-3 (n-3 PUFA) polyunsaturated fatty acids on the performance and the immune response of broilers submitted to an antigenic challenge. Diets were formulated with either 7% soybean oil (SO), linseed oil (LO) or sardine oil (PO) and provided to 240 Cobb broilers which were divided into 24 groups of 10 birds each, following a 3x2 experimental arrangement (3 types of oil and vaccinated or non-vaccinated birds) and four replications. Soybean oil is rich in linoleic acid (n-6 PUFA), linseed oil a source of alfa-linolenic acid (n-3 PUFA) and the sardine oil is a source of eicosapentaenoic and docosahexaenoic acids (other n-3 PUFA). Feed intake, weight gain and feed conversion were evaluated at 21, 35 and 42 days. Half of the birds were vaccinated against Newcastle disease at 7 and 21 days. Fifteen days after the immunization, the production of antibodies was evaluated by ELISA and expressed by optical density at 450 nm (O.D. 450 nm). Only the birds fed ration containing SO presented higher humoral immune response (p<0.05) after vaccination. The lymphoproliferative response, which expresses the cellular immunity, was higher in vaccinated than in the unvaccinated birds (P<0.05), regardless of the oil used. Neither the oil source in the ration nor the vaccination influenced birds' weight gain (P>0.05). The vaccination impaired the feed conversion of the birds fed diet containing SO (P<0.05) but did not influence feed conversion of the birds fed rations with LO or PO (P>0.05). The use of oil rich in n-6 PUFA in broilers' diet increased humoral response, but did not influence the cellular response against an antigenic challenge.

Introdução: Poucos estudos avaliaram o perfil do uso de drogas modificadoras de doença (DMD) em pacientes brasileiros com diagnóstico de espondiloartrite (EpA). Métodos: Um protocolo comum de investigação foi prospectivamente aplicado em 1505 pacientes classificados como EpA pelos critérios do Grupo Europeu de Estudo das Espondiloartrites (ESSG), acompanhados em 29 centros de referência em Reumatologia no Brasil. Variáveis clínicas e demográficas foram obtidas e avaliadas, analisando-se suas correlações com o uso das DMD metotrexato (MTX) e sulfasalazina (SSZ). Resultados: Pelo menos uma DMD foi utilizada por 73,6% dos pacientes, sendo MTX por 29,2% e SSZ por 21,7%, enquanto 22,7% utilizaram ambas as drogas. O uso do MTX foi significativamente associado ao acometimento periférico, e a SSZ foi associada ao comprometimento axial, sendo que as duas drogas foram mais utilizadas, isoladas ou combinadas, no comprometimento misto (p < 0,001). O uso de uma DMD esteve significativamente associado à etnia branca (MTX; p = 0,014), lombalgia inflamatória (SSZ; p = 0,002), dor em nádegas (SSZ; p = 0,030), cervicalgia (MTX; p = 0,042), artrite de membros inferiores (MTX; p < 0,001), artrite de membros superiores (MTX; p < 0,001), entesite (p = 0,007), dactilite (MTX; p < 0,001), doença inflamatória intestinal (SSZ; p < 0,001) e acometimento ungueal (MTX; p < 0,001). Conclusão: O uso de pelo menos uma DMD foi referido por mais de 70% dos pacientes numa grande coorte brasileira de pacientes com EpA, sendo o uso do MTX mais associado ao acometimento periférico e o uso da SSZ mais associado ao acometimento axial.
Introduction: Few studies have evaluated the profile of use of disease modifying drugs (DMD) in Brazilian patients with spondyloarthritis (SpA). Methods: A common research protocol was applied prospectively in 1505 patients classified as SpA by criteria of the European Spondyloarthropathies Study Group (ESSG), followed at 29 referral centers in Rheumatology in Brazil. Demographic and clinical variables were obtained and evaluated, by analyzing their correlation with the use of DMDs methotrexate (MTX) and sulfasalazine (SSZ). Results: At least one DMD was used by 73.6 % of patients: MTX by 29.2 % and SSZ by 21.7%, while 22.7 % used both drugs. The use of MTX was significantly associated with peripheral involvement, and SSZ was associated with axial involvement, and the two drugs were more administered, separately or in combination, in the mixed involvement (p < 0.001). The use of a DMD was significantly associated with Caucasian ethnicity (MTX , p = 0.014), inflammatory back pain (SSZ, p = 0.002) , buttock pain (SSZ, p = 0.030), neck pain (MTX, p = 0.042), arthritis of the lower limbs (MTX, p < 0.001), arthritis of the upper limbs (MTX, p < 0.001), enthesitis (p = 0.007), dactylitis (MTX, p < 0.001), inflammatory bowel disease (SSZ, p < 0.001) and nail involvement (MTX, p < 0.001). Conclusion: The use of at least one DMD was reported by more than 70% of patients in a large cohort of Brazilian patients with SpA, with MTX use more associated with peripheral involvement and the use of SSZ more associated with axial involvement.

The objective of the present cross-sectional study was to assess the prevalence and the clinical and laboratory features of hepatitis C virus (HCV)-positive patients with type 2 diabetes mellitus (DM) attending either an outpatient clinic or hemodialysis units. Serologic-HCV testing was performed in 489 type 2 DM patients (303 outpatients and 186 on dialysis). A structured assessment of clinical, laboratory and DM-related complications was performed and the patients were then compared according to HCV infection status. Mean patient age was 60 years; HCV positivity (HCV+) was observed in 39 of 303 (12.9%) outpatients and in 34 of 186 (18.7%) dialysis patients. Among HCV+ patients, 32 were men (43.8%). HCV+ patients had higher serum levels of aspartate aminotransferase (0.90 ± 0.83 vs 0.35 ± 0.13 µKat/L), alanine aminotransferase (0.88 ± 0.93 vs 0.38 ± 0.19 µKat/L), gamma-glutamyl transferase (1.57 ± 2.52 vs 0.62 ± 0.87 µKat/L; P < 0.001), and serum iron (17.65 ± 6.68 vs 14.96 ± 4.72 µM; P = 0.011), and lower leukocyte and platelet counts (P = 0.010 and P < 0.001, respectively) than HCV-negative (HCV-) patients. HCV+ dialysis patients had higher diastolic blood pressure than HCV- patients (87.5 ± 6.7 vs 81.5 ± 6.0 mmHg; P = 0.005) and a lower prevalence of diabetic retinopathy (75 vs 92.7%; P = 0.007). In conclusion, our study showed that HCV is common among subjects with type 2 DM but is not associated with a higher prevalence of chronic diabetic complications.

The maternal history of type 2 diabetes mellitus (DM) has been reported more frequently in patients with type 2 DM than paternal history. The aim of the present study was to determine if there was an association between maternal history of DM and the presence of chronic complications or metabolic syndrome (MetS) in patients with type 2 DM. A cross-sectional study was conducted with 1455 patients with type 2 DM. All outpatients with type 2 diabetes attending the endocrine clinics who fulfilled the eligibility criteria were included. Familial history of DM was determined with a questionnaire. Diabetic complications were assessed using standard procedures. The definition of MetS used was that of the World Health Organization and the National Cholesterol Education Program's Adult Treatment Panel III report criteria. Maternal history of DM was present in 469 (32.3%), absent in 713 (49.1%) and unknown in 273 patients (18.7%). Paternal history of DM was positive in 255 (17.6%), negative in 927 (63.8%) and unknown in 235 patients (16.1%). The frequency of microvascular chronic complications in patients with and without a positive maternal history of DM was similar: diabetic nephropathy (51.5 vs 52.5%), diabetic retinopathy (46.0 vs 41.7%), and diabetic sensory neuropathy (31.0 vs 37.1%). The prevalence of macrovascular chronic complications and MetS was also similar. Patients with type 2 DM were more likely to have a maternal than a paternal history of DM, although maternal history of DM was not associated with an increased prevalence of chronic complications or MetS.

Foi avaliada a eficácia no controle de arroz-vermelho com o herbicida nicosulfuron ou a mistura formulada de imazethapyr + imazapic. O experimento foi conduzido em casa de vegetação da Faculdade de Agronomia Eliseu Maciel (UFPel), no município de Capão do Leão (RS), na estação de crescimento 2005/06, em delineamento experimental de blocos ao acaso, com quatro repetições. Os tratamentos foram arranjados em esquema fatorial 2 x 7, sendo o fator A os herbicidas e o fator B as doses dos herbicidas (0, 0,25, 0,50, 0,75, 1,0, 1,25 e 1,50 L ha-1). A aplicação foi feita sobre as plantas de arroz-vermelho em estádio de desenvolvimento V4. As variáveis analisadas foram controle, estatura da planta e massa seca da parte aérea. Para as variáveis respostas foi verificada interação significativa entre os fatores estudados. Incrementos nas doses dos herbicidas resultaram em respostas crescentes de controle, com redução na taxa de crescimento das plantas e produção de massa seca da parte aérea. Os resultados mostraram que o arroz-vermelho é controlado pelos herbicidas testados. A eficácia de controle não é restrita à mistura formulada de imazethapyr + imazapic, ocorrendo também com o herbicida nicosulfuron a partir de 40 g ha-1.
Red rice control efficacy using nicosulfuron or a formulated mixture of imazethapyr + imazapic was evaluated. A greenhouse experiment was carried out at Faculdade de Agronomia Eliseu Maciel (UFPel) in Capão do Leão (RS), during the 2005/2006 growing season, in a randomized complete block design and four replications. Treatments were arranged in a 2 x 7 factorial, with factor A being the herbicides and factor B the herbicide rates (0, 0.25, 0.50, 0.75, 1.0, 1.25 and 1.50 L ha-1). The herbicides were applied over red rice plants at the V4 development stage. Control, plant height and aerial dry mass were evaluated. There was a significant interaction for the variables between the factors studied. Increased herbicide rates resulted in increasing control responses and decreased plant height and dry biomass. Results showed that red rice is efficiently controlled by the herbicides. Control efficacy is not restricted to the formulated mixture of imazethapyr+imazapic, also occurring with nicosulfuron starting from 40 g ha-1.
