RESUMO: Aeromonas sp. são bactérias presentes naturalmente no ecossistema aquático e apresentam potencial patogênico, sendo considerados patógenos emergentes em humanos e animais. Ainda, causam perdas consideráveis em piscicultura e, através da água, podem também contaminar inúmeros alimentos. Diante disso o objetivo do trabalho foi quantificar e analisar o perfil de resistência aos antimicrobianos de bactérias do gênero Aeromonas sp. em peixes. Um total de 72 amostras foram adquiridas, sendo duas variedades de peixes (peixe de couro Pseudoplatystoma fasciatum x Leiarius marmoratus e os peixes redondos Colossoma macropomum x Piaractus mesopotamicus e Colossoma macropomum x Piaractus brachypomus), dois tipos (fresco e congelado) e de três estabelecimentos comerciais (supermercado, feira e peixaria). As 55 culturas isoladas de Aeromonas foram avaliadas quanto ao perfil de resistência aos antimicrobianos pelo método de difusão em disco. Os valores encontrados na quantificação de Aeromonas sp. variaram de 4,22 a 6,00 Log UFC/g, e foram identificadas dez espécies diferentes, sendo A. eucrenophila, A. hydrophila, A. caviae, A. media, A. jandaei, A. veronii bv. sobria, A. trota, A. schubertii, A. veronii bv. veronii e A. shigelloides. Entre os 55 isolados, 64,45% apresentaram resistência a Ampicilina-sulbactam, 75% foram sensíveis à gentamicina e ciprofloxacina. Concluiu-se que 100% das amostras avaliadas estavam contaminadas por Aeromonas sp. podendo apresentar risco à saúde do consumidor visto que estas podem ser agentes etiológicos de Doenças Transmitidas por Alimentos (DTAs). O perfil de resistência aos antimicrobianos comprovou a resistência a ampicilina e apresentou multirresistência a diferentes classes de antimicrobianos, demonstrando um problema relacionado à opção de antimicrobiano para tratamento no caso do desenvolvimento de alguma doença.

ABSTRACT: The bacteria Aeromonassp. are naturally reported in aquatic ecosystems and possess pathogenic potential, being considered as emerging pathogens in humans and animals. They also cause considerable losses in fish farming and, through water, can contaminate numerous foods. This study quantified and analyzed the antimicrobial resistance profile of Aeromonassp. in fish. A total of 72 samples of two fish varieties (leather fish, Pseudoplatystomafasciatumx Leiariusmarmoratusand round fish, Colossomamacropomumx Piaractusmesopotamicusand Colossomamacropomumx Piaractusbrachypomus) were purchased from two types of sources (fresh and frozen) and three commercial establishments (supermarket, market, and fishmonger). The 55 isolated Aeromonascultures were evaluated for their antimicrobial resistance profile by the disc diffusion method. Upon quantification, the count of Aeromonassp. ranged from 4.22 to 6.00 Log CFU/g; ten different species, including A. eucrenophila, A. hydrophila, A. caviae, A. media, A. jandaei, A. veroniibv. sobria, A. trota, A. schubertii, A. veroniibv. veronii, and A. shigelloides, were identified. Among the 55 isolates, 64.45% showed resistance to Ampicillin-sulbactam, and 75% were sensitive to gentamicin and ciprofloxacin. It was concluded that 100% of the evaluated samples were contaminated by Aeromonassp., which may present a risk to consumer health since bacteria can be etiological agents of Foodborne Diseases. The antimicrobial resistance profile showed resistance to ampicillin and multi-resistance to different classes of antimicrobials, demonstrating problems with choosing an antimicrobial for treatment of any disease.

ABSTRACT Background: SARS-CoV-2 virus originated in Wuhan (China) in December (2019) and quickly spread worldwide. Antigen tests are rapid diagnostic tests (RDT) that produce results in 15-30 min and are an important tool for the scale-up of COVID-19 testing. COVID-19 diagnostic tests are authorized for self-testing at home in some countries, including Brazil. Widespread COVID-19 diagnostic testing is required to guide public health policies and control the speed of transmission and economic recovery. Methods: Patients with suspected COVID-19 were recruited at the Hospital da Baleia (Belo Horizonte, Brazil). The SARS-CoV-2 antigen-detecting rapid diagnostic tests were evaluated from June 2020 to June 2021 using saliva, nasal, and nasopharyngeal swab samples from 609 patients. Patient samples were simultaneously tested using a molecular assay (RT-qPCR). Sensitivity, specificity, accuracy, and positive and negative predictive values were determined using the statistical program, MedCalc, and GraphPad Prism 8.0. Results: The antigen-detecting rapid diagnostic tests displayed 98% specificity, 60% sensitivity, 96% positive predictive value, and moderate concordance with RT-qPCR. Substantial agreement was found between the two methods for patients tested < 7 days of symptom onset. Conclusions: Our findings support the use of Ag-RDT as a valuable and safe diagnostic method. Ag-RDT was also demonstrated to be an important triage tool for suspected COVID-19 patients in emergencies. Overall, Ag-RDT is an effective strategy for reducing the spread of SARS-CoV-2 and contributing to COVID-19 control.

ABSTRACT Objective Peak oxygen consumption (VO2peak), anaerobic threshold, walking economy, and cardiovascular responses during walking are used to guide and monitor walking training in patients with peripheral artery disease and intermittent claudication. Women with peripheral artery disease and intermittent claudication present greater impairments than men, and evaluating training markers according to sex for decisions regarding walking prescription in this population is important. This study aimed to compare VO2peak, walking economy, anaerobic threshold, and cardiovascular responses during walking in men and women with peripheral artery disease and intermittent claudication. Methods Forty patients (20 men and 20 women with similar baseline characteristics) underwent a cardiopulmonary treadmill test (3.2km/h and 2% increase in slope every 2 minutes until maximal leg pain). The VO2 and rate-pressure product were assessed. Data from men and women were compared using t-tests. Results There were no significant differences between men and women (VO2peak: 15.0±4.8 versus 13.9±2.9mL∙kg-1∙min-1, p=0.38; walking economy: 9.6±2.7 versus 8.4±1.6mL∙kg-1∙min-1, p=0.09; anaerobic threshold: 10.5±3.2 versus 10.5±2.2mL∙kg-1∙min-1, p=0.98; rate pressure product at 1st stage: 13,465± 2,910 versus 14,445±4,379bpm∙mmHg, p=0.41; and rate pressure product at anaerobic threshold:13,673±3,100 versus 16,390±5,870bpm∙mmHg, p=0.08 and rate pressure product at peak exercise: 21,253±6,141 versus 21,923±7,414bpm∙mmHg, p=0.76, respectively). Conclusion Men and women with peripheral artery disease and similar baseline characteristics presented similar responses to walking, suggesting that decisions regarding walking prescription and monitoring can be made regardless of sex in this specific population.

Abstract Enterolobium cyclocarpum is a multipurpose tree species whose growth and survival in plantations are unknown. The objective was to evaluate the effect of different nursery growing media and auxiliary treatments to mitigate water stress on the performance of E. cyclocarpum plants established in the field. The seeds were sown in three different types of substrates: 1) base mixture (peat, vermiculite and agrolite), 2) aerobic compost and 3) native soil. Each group of plants by type of substrate was divided into four subgroups that were assigned different auxiliary treatment to mitigate water stress: 1) irrigation, 2) hydrogel (2 g plant-1), 3) hydrogel (4 g plant-1) and 4) natural conditions (control). The results indicate that the type of substrate influences the survival and growth of the plants, being native soil the one that promotes higher values. It was found that there is a positive relationship between the diameter of the plants and the probability of survival, this variable being a basic quality indicator of the plants grown in the nursery. The auxiliary treatment of hydric stress significantly affected the growth in diameter and height, being irrigation the one that increased the values, with the exception of the diameter in the base mixture.

Resumen Enterolobium cyclocarpum es una especie arbórea multipropósito cuyo crecimiento y supervivencia en plantaciones se desconoce. El objetivo fue evaluar el efecto de tres medios de crecimiento en vivero y tratamientos auxiliares para mitigar el estrés hídrico en el desempeño de plantas de E. cyclocarpum establecidas en campo. Las semillas se sembraron en tres diferentes tipos de sustrato: 1) mezcla base (turba, vermiculita y agrolita), 2) composta aeróbica, y 3) tierra de monte. Cada grupo de plantas por tipo de sustrato se dividió en cuatro subgrupos a los que se les asignó diferente tratamiento auxiliar para mitigar el estrés hídrico: 1) riego, 2) hidrogel (2 g planta-1), 3) hidrogel (4 g planta-1), y 4) condiciones naturales (testigo). Los resultados indican que el tipo de sustrato influye en la supervivencia y crecimiento de las plantas, siendo la tierra de monte la que promueve mayores valores. La relación entre el diámetro de plantas con la probabilidad de supervivencia fue positiva; esta variable es un indicador de la supervivencia en campo durante los primeros años de la plantación. El tratamiento auxiliar para mitigar el estrés hídrico afectó significativamente el crecimiento en diámetro y altura; el riego aumentó los valores, con excepción del diámetro en mezcla base.

SUMMARY OBJECTIVE: This study aimed to validate the internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire. METHODS: A cross-sectional study was conducted with individuals over 18 years old of both sexes, with Brazilian Portuguese as their native language. The structure of the Baecke Habitual Physical Activity Questionnaire was tested by confirmatory factor analysis. The model fit was evaluated by the following indices: root mean square error of approximation, comparative fit index, Tucker-Lewis index, standardized root mean square residual, and χ²/degrees of freedom. We used the Akaike information criterion and Bayesian information criterion to compare different structures of the Baecke Habitual Physical Activity Questionnaire. RESULTS: A total of 241 individuals participated in this study. The original structure of the Baecke Habitual Physical Activity Questionnaire with 16 items and 3 domains was compared to a structure with 14 items and 3 domains. The internal structure of the Baecke Habitual Physical Activity Questionnaire with 14 items showed better fit indices and lower Akaike information criterion and Bayesian information criterion values. CONCLUSION: The best internal structure of the Brazilian version of the Baecke Habitual Physical Activity Questionnaire in adults presents 3 domains and 14 items.

Resumen Este artículo plantea una reflexión teórico-narrativa sobre lo que se ha denominado «Espiritualidad martirial». La conceptualización de la espiritualidad y el martirio se realizó a través de una investigación exploratorio-bibliográfica. La discusión central se tejió en diálogo, sobre todo, con los estudios teológicos de Casaldáliga, Sobrino y Gutiérrez. Las conclusiones apuntan en el sentido de que la espiritualidad del martirio no está relacionada con el deseo de ser mártir. El martirio tampoco está relacionado con la concepción del sacrificio sangriento como redentor del pecado. La espiritualidad del martirio se refiere a la fidelidad al Evangelio del perseguido y mártir, Jesús de Nazaret. Asimismo, se trata de la fidelidad a la realidad histórica actual y concreta en la que el cristiano debe anunciar la buena nueva a los pobres y denunciar la injusticia estructural. Finalmente, se trata del recuerdo de la muerte de los inocentes y de la línea de seguidores de Jesús que fueron martirizados.

Resumo O presente artigo traz à baila uma reflexão teórico-narrativa acerca daquela que tem sido chamada «Espiritualidade Martirial». A conceituação sobre espiritualidade e martírio deu-se por meio de pesquisa exploratório-bibliográfica. A discussão central foi tecida em diálogo, sobretudo, com os estudos teológicos de Casaldáliga, Sobrino e Gutierrez. As conclusões apontam no sentido de que a Espiritualidade Martirial não está relacionada ao desejo de ser mártir. Tampouco o martírio relaciona-se à concepção de sacrifício cruento como redentor de pecado. A Espiritualidade Martirial diz respeito à fidelidade ao Evangelho do perseguido e mártir, Jesus de Nazaré. De igual modo, diz respeito à fidelidade à realidade histórica atual e concreta na qual o cristão deve anunciar boas notícias aos pobres e denunciar a injustiça estrutural. Por fim, diz respeito à memória da morte dos inocentes e à fileira dos seguidores de Jesus que foram martirizados.

Abstract This article brings up a theoretical-narrative reflection on what has been called «Martyrial Spirituality». The conceptualization of spirituality and martyrdom took place through exploratory-bibliographic research. The central discussion was woven in dialogue, above all, with the theological studies of Casaldáliga, Sobrino and Gutierrez. The conclusions point in the sense that Martyrdom Spirituality is not related to the desire to be a martyr. Nor is martyrdom related to the conception of the bloody sacrifice as the redeemer of sin. Martyrdom Spirituality concerns fidelity to the Gospel of the persecuted and martyr, Jesus of Nazareth. Likewise, it concerns fidelity to the current and concrete historical reality in which the Christian must announce good news to the poor and denounce structural injustice. Finally, it concerns the memory of the death of the innocent and the line of followers of Jesus who were martyred.

RESUMO Bromélia Quesnelia quesneliana (Brongniart) L.B. Smith foi relatada na Mata Atlântica, Floresta Úmida, Floresta Estacional Semidecidual Mesofílica, Manguezais e Restingas nos estados do sudeste brasileiro do Rio de Janeiro e Espírito Santo, mas informações sobre a morfologia de frutos e sementes e germinação são limitadas. O objetivo neste estudo foi caracterizar a morfologia externa dos frutos e sementes, germinação e estádios pós-seminais de Q. quesneliana. Os frutos foram coletados na área da Restinga, município de Armação dos Búzios, Rio de Janeiro, Brasil. A largura e o comprimento dos frutos e sementes (morfologia externa) foram medidos e o desenvolvimento pós-seminal das sementes foi analisado, como também elaboradas ilustrações botânicas. Foram calculados os índices t50, uniformidade de germinação, tempo médio de germinação e coeficiente de velocidade de germinação. A germinação foi avaliada por 20 dias por meio da contagem de indivíduos para obtenção dos estágios pós-seminais. Os frutos maduros da Q. quesneliana são piriformes, de cor marrom-avermelhada, manchas claras, com 26 mm de comprimento e 10 mm de largura na porção mais dilatada, contendo em média 148 sementes, envolvidas por mucilagem transparente. As sementes possuem comprimentos de 2 mm e 1 mm de largura, com germinação do tipo epígea e com plântulas do tipo criptocotiledôneas. As sementes dessa espécie germinam rápido e não possuem dormência.

ABSTRACT Bromeliad Quesnelia quesneliana (Brongniart) L.B. Smith has been reported in the Atlantic Forest, Rainforest, Mesophilic Semideciduous Seasonal Forest, Mangroves and Restingas in the Brazilian southeastern states of Rio de Janeiro and Espírito Santo, but information about their fruit and seed morphology, and germination is limited. The aim of this study was to characterize the external morphology of fruit and seeds, germination rate and post-seminal stages of Q. quesneliana. Fruits were collected from Restinga area in the Armação dos Búzios city, Rio de Janeiro, Brazil. The width and length of fruit and seeds (external morphology) were measured, the post-seminal development of the seeds was analyzed and botanical illustrations were made. The indexes t50, uniformity of germination, mean germination time and germination speed coefficient were also calculated. Germination was assessed for 20 days by counting individuals to obtain the post-seminal stages. Ripe Q. quesneliana fruits are pyriform, reddish-brown in color, with light spots, 26 mm long and 10 mm wide, with an average of 148 seeds per fruit and wrapped in a transparent mucilage. The seeds are 2 mm long and 1 mm wide, with epigeal germination, and its seedlings are cryptocotyledonary. The seeds of this species germinate quickly and have no dormancy.

Abstract Since the arrival of varroa (Varroa destructor) in Mexico, more than 33 % of the hives in the highland and northern regions of the country have been lost annually, due to the excessive use of synthetic acaricides, which have developed resistance in the populations of these mites. Due to this, the objective of this research was to evaluate the fall of V. destructor mites, as well as the percentage of infestation through the application of botanical grinds of garlic (Allium sativum), laurel (Laurus nobilis) and oregano (Origanum vulgare) in Apis mellifera colonies in winter season. 16 jumbo-type hives were used, thus four hives per treatment, where each hive was the experimental unit. The treatments were: 1) Control (no treatment); 2) garlic; 3) laurel, and 4) oregano. Treatments included powdered sugar in a 1:1 ratio. Data were analyzed as a completely randomized design. The percentage of initial infestation (covariate) does not represent significance (p > 0.05). Laurel presented the highest value (42.46 ± 12.07) for the number of fallen mites. From day 7 the infestation percentages decrease, highlighting laurel (p < 0.01). The group of control hives showed an upward trend, with averages higher than 5 % (5.32 ± 1.16). At present, the research area regarding the efficacy of botanical grinds in beekeeping is limited, therefore, the use of bioacaricides as botanical grinds represents an alternative for the control of the V. destructor mite, since they are ingredients of easy accessibility, they present a low cost and a simple methodology of elaboration and application. In addition, being an organic treatment, it guarantees environmental, obtaining safety in honey and by-products derived from the hive previously treated.

Resumen Anualmente, se pierde más del 33 % de las colmenas en el altiplano y el norte de México por varroa (Varroa destructor), debido al uso excesivo de acaricidas sintéticos. Como resultado, las poblaciones de ácaros han desarrollado resistencia. El objetivo de esta investigación fue evaluar la caída de ácaros de V. destructor, así como el porcentaje de infestación mediante la aplicación de moliendas botánicas de ajo (Allium sativum), laurel (Laurus nobilis) y orégano (Origanum vulgare) en colonias de Apis mellifera en temporada invernal. Se utilizaron 16 colmenas tipo jumbo, seleccionando cuatro colmenas por tratamiento, donde cada una fue la unidad experimental. Los tratamientos fueron: 1) testigo (sin tratamiento); 2) ajo; 3) laurel, y 4) orégano. Los tratamientos incluyeron azúcar pulverizada (glass) en proporción 1:1 (azúcar: molienda vegetal). Los datos se analizaron mediante un diseño completamente aleatorizado. Se consideró el porcentaje de infestación inicial (covariable) para determinar si afectaba la respuesta a las moliendas (p > 0.05). El laurel presentó el mayor número de ácaros caídos (42.46 ± 12.07). A partir del día siete, los porcentajes de infestación decrecieron, destacando la molienda de laurel (p < 0.01). El grupo de las colmenas testigo presentó una tendencia creciente, con medias superiores al 5 % (5.32 ± 1.16). En la actualidad, se están usando los aceites y extractos botánicos para el tratamiento de plagas y enfermedades de las abejas. Sin embargo, la utilización de moliendas botánicas en la apicultura es limitada, por lo anterior, el uso de estos bioacaricidas representa una alternativa para el control del ácaro V. destructor, ya que son ingredientes de fácil accesibilidad, presentan un bajo costo y una metodología sencilla de elaboración y aplicación. Además, al ser un tratamiento orgánico, garantiza la seguridad ambiental, obteniendo inocuidad en la miel y en subproductos derivados de la colmena.

Resumo O açaizeiro é a principal palmeira cultivada na Amazônia brasileira, e a diagnose nutricional torna-se uma ferramenta essencial ao manejo da cultura. O objetivo deste trabalho foi determinar a folha padrão para a diagnose nutricional do açaizeiro por meio da avaliação dos teores foliares e da utilização de dois métodos de análises estatísticas, tradicional (univariada) e multivariada. O estudo foi conduzido no munícipio de Belém - PA, com oito tratamentos: posições filotáxicas das folhas (folhas 2 a 9), em delineamento inteiramente casualizado. A concentração foliar dos nutrientes (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn) foi determinada para a realização das análises descritivas, de variância, correlação e análise de componentes principais. As folhas novas apresentaram maiores concentrações de N, P, K, Mg, S, Cu e Zn, ao passo que, nas folhas mais velhas, houve maiores concentrações de Ca, B, Fe e Mn. As folhas que apresentaram menor variação nas concentrações dos nutrientes foram de 2 a 5. A análise de PCA indicou interação de cargas positivas de N-P e Cu-Mg e interação de cargas negativas de Ca-Mn. O índice de distribuição dos nutrientes indicou a folha 5 com o menor valor de carga fatorial. Nesse sentido, a folha número 5 é a mais indicada para a diagnose nutricional de plantas de açaizeiro por meio de amostragem de 25 plantas.

Abstract Assai palm is the main palm tree grown in the Brazilian Amazon. Nutritional diagnosis has become an essential tool in management of the crop. The aim of this study was to determine the standard leaf for nutritional diagnosis of the assai palm tree through evaluation of leaf nutrient content and use of two methods of statistical analyses: traditional (univariate) and multivariate. The study was conducted in the municipality of Belém, with eight treatments: the phyllotaxic positions of the leaves (number 2 to 9), in a completely randomized design. The leaf concentration of nutrients (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn) was determined for performing descriptive analyses, analyses of variance, correlation analysis, and principal component analysis (PCA). Young leaves had greater concentrations of N, P, K, Mg, S, Cu, and Zn, whereas in the older leaves, there were greater concentrations of Ca, B, Fe, and Mn. The leaves that exhibited less variation in nutrient concentrations were from 2 to 5. PCA analysis indicated interaction of positive loads of N-P and Cu-Mg and interaction of negative loads of Ca-Mn. The index of nutrient distribution indicated leaf number 5 as having the lowest factor loading value. Thus, leaf number 5 is most recommended for nutritional diagnosis of assai palm plants through sampling of 25 plants.

Resumo: A deterioração por umidade na fase de pré-colheita prejudica a obtenção de sementes de soja de alta qualidade. Em seleção de genótipos, é comum a realização de vários testes para inferir sobre qualidade de sementes, sendo que a estatística multivariada pode auxiliar nas interpretações. O objetivo do trabalho foi avaliar a eficiência dos métodos de estatística multivariada de componentes principais (PCA) e discriminantes canônicos (CDA) na avaliação da tolerância de sementes de diferentes cultivares de soja à deterioração por umidade na fase de pré-colheita, em condições de casa de vegetação. Foram produzidas sementes de seis cultivares de soja (DM 6563, BMX Apolo, BMX Potência, NA 5909, NS 5959 e TMG 1175). Na fase de pré-colheita, foram aplicados diferentes níveis de precipitação simulada (0, 60, 120 e 180 mm). As sementes foram colhidas e avaliadas quanto a análises fisiológicas, físicas e bioquímicas e os dados obtidos foram analisados pelas técnicas PCA e CDA. Os resultados mostraram que a PCA e a CDA são eficientes para avaliação da tolerância à deterioração por umidade em sementes de soja. Na pré-seleção de genótipos para essa característica, a PCA e a CDA auxiliaram na recomendação dos testes de primeira contagem de germinação, envelhecimento acelerado, tetrazólio, porcentagem de sementes com enrugamento no tegumento, teor de proteínas e atividade da protease. A PCA e a CDA também auxiliaram na identificação das cultivares DM 6563 e BMX Potência como mais suscetíveis e as cultivares NA 5909 e TMG 1175 como mais tolerantes à deterioração por umidade na fase de pré-colheita.

Abstract: Weathering deterioration in the pre-harvest phase impairs high-quality soybean seed production. The performance of several tests to infer seed quality is common in genotype selection, and multivariate statistics can assist in the interpretations. This study aimed to assess the efficiency of the principal component analysis (PCA) and canonical discriminant analysis (CDA) multivariate statistical methods in assessing the tolerance of seeds of different soybean cultivars to weathering deterioration in the pre-harvest phase under greenhouse conditions. Seeds of six soybean cultivars (DM 6563, BMX Apolo, BMX Potência, NA 5909, NS 5959, and TMG 1175) were produced. Different simulated precipitation levels (0, 60, 120, and 180 mm) were applied in the pre-harvest phase. The seeds were collected and assessed for physiological, physical, and biochemical analyses and the data were analyzed by PCA and CDA techniques. The results showed that PCA and CDA are efficient for assessing the tolerance to weathering deterioration in soybean seeds. PCA and CDA assisted in the recommendation of the tests first germination count, accelerated aging, tetrazolium, percentage of seeds with seed coat wrinkling, protein content, and protease activity in the pre-selection of genotypes for weathering deterioration. PCA and CDA also helped to identify the cultivars DM 6563 and BMX Potência as more susceptible and NA 5909 and TMG 1175 as more tolerant to weathering deterioration in the pre-harvest phase.

Resumo Mesmo no período em que a pandemia de Covid-19 encontrava-se em crescimento no Nordeste do Brasil, iniciou-se a adoção de medidas de flexibilização do distanciamento social. O objetivo do estudo é o de avaliar a pertinência das propostas de flexibilização, tomando-se em conta a situação da pandemia em cada local e o momento em que foram adotadas. Tendo como referência as diretrizes da OMS, foram construídos e analisados indicadores operacionais para cada diretriz, no contexto da região Nordeste. Para análise do comportamento da epidemia, conforme indicadores selecionados, foram usadas técnicas de Joinpoint Trend Analysis, mapas de calor, razão de taxas e comparação da tendência temporal entre capitais e interior dos estados. O pico do crescimento semanal ocorreu em maio-julho/2020 (semanas epidemiológicas 19 a 31). Na maioria das capitais não se observou tendência decrescente simultânea do número de casos e óbitos nos 14 dias prévios à flexibilização. Em todos os estados o quantitativo de testes realizados foi insuficiente. Na semana epidemiológica 24 os percentuais estaduais de ocupação de leitos de UTI/Covid-19 foram próximos ou superiores 70%. A situação epidemiológica das nove capitais dos estados do Nordeste, no momento em que a decisão de flexibilização foi tomada, mostra que nenhuma delas atendia aos critérios e parâmetros recomendados pela OMS.

Abstract Even in the period when the Covid-19 pandemic was on the rise in the Northeast of Brazil, the relaxation of social distancing measures was introduced. The scope of the study is to assess, in the light of the epidemiological-sanitary situation in the region, the suitability of relaxation of social distancing measures. Based on the WHO guidelines for relaxation of social distancing, operational indicators were created and analyzed for each guideline in the context of the Northeast. To analyze the behavior of the epidemic, according to selected indicators, Joinpoint trend analysis techniques, heat maps, rate ratios and time trends between capitals and the state interior were compared. The weekly growth peak of the epidemic occurred in May-July 2020 (epidemiological weeks 19 to 31). In most capitals, there was no simultaneous downward trend in the number of cases and deaths in the 14 days prior to flexibilization. In all states the number of tests performed was insufficient. In epidemiological week 24, the state percentages of ICU/Covid-19 bed occupancy were close to or above 70%. The epidemiological situation of the nine Northeastern state capitals analyzed here did not meet criteria and parameters recommended by the World Health Organization for the relaxation of social distancing measures.

Resumo A infecção por Neospora caninum é considerada uma das principais causas de aborto entre bovinos. Esta pesquisa foi realizada no município de Rolim de Moura, estado de Rondônia, Brasil. Um questionário que investiga os aspectos epidemiológicos da neosporose foi utilizado na análise dos fatores de risco associados à prevalência em animais e em rebanhos. Um total de 416 amostras de sangue bovino foi colhido em 30 fazendas, e os níveis de anticorpos de N. caninum foram mensurados pela reação de Imunofluorescência Indireta (RIFI). A análise das amostras mostrou prevalência de anticorpos contra N. caninum de 47,36% (n = 197). Os fatores de risco associados à infecção por N. caninum foram o sistema de manejo e os locais de acesso dos cães. Os resultados da presente pesquisa indicam que a infecção de bovinos leiteiros com N. caninum está disseminada na região estudada da Amazônia Ocidental, o que tem implicações para a prevenção e controle da neosporose nessa região. Portanto, estratégias e medidas de controle integrado são recomendadas para prevenir e controlar a infecção por N. caninum em gado leiteiro. Além disso, o contato íntimo entre gado leiteiro, cães e animais selvagens, pode influenciar a epidemiologia da neosporose e deve ser investigada mais detalhadamente.

Abstract Neospora caninum is considered to be one of the main causes of abortion among cattle. The present survey was conducted in the municipality of Rolim de Moura, Rondônia State, Brazil. A questionnaire that investigates the epidemiological aspects of neosporosis was used in the analysis of risk factors associated with the animal-level and herd-level prevalence in dairy cattle. A total of 416 bovine blood samples were collected from 30 farms, and N. caninum antibody levels were measured by Indirect Fluorescent Antibody Test (IFAT). Analysis of dairy cattle serum samples revealed the presence of anti-N. caninum antibodies to be 47.36% (n = 197). Risk factors associated with N. caninum infection were the management system and access locations of dogs. The results of the present survey indicated that infection of dairy cattle with N. caninum is widespread in the studied region of Western Amazon, which has implications for prevention and control of neosporosis in this region. Therefore, integrated control strategies and measures are recommended to prevent and control N. caninum infection in dairy cattle. In addition, direct contact between dairy cattle, dogs and wild animals, which can influence the epidemiology of neosporosis, should be investigated further.
