    To pathological assessments or recognition of changes in the morphology of these is necessary knowledge of a normal morphological pattern, being this then the goal of this study. Were collected 20 animals (Piaractus mesopotamicus), from cultivation environments the region of Grande Dourados, with total length of 35 cm and 750 g approximately. During data collection, the animals were anesthetized with benzocaine, euthanized and dissected for macroscopic evaluation of organs "in situ". After, collected the gills, fixed in Bouin solution and stained by the usual method Hematoxylin-eosin and alcian blue technique+ PAS. Macroscopically it was observed that these had brilliant crimson red coloration, located internally, protected by beeswax, with numerous traces spaced, filaments and secondary lamellae. Under light microscopy was possible to identify the branchial artery, cartilaginous structure, cells pillars, respiratory epithelium and mucous cells. We concluded that this species has a branchial structure very similar to that of other freshwater teleosteans, although more studies are necessary to compare this structure in all phases of his life and times of the year.In order to carry out pathological evaluations or recognition of changes in the morphology of pacu gills, it is necessary to know a regular morphological pattern, which is the purpose of this study. Twenty animals (Piaractus mesopotamicus) were collected from cultivated environments of the “Grande Dourados” region, Mato Grosso do Sul State, Brazil, with an average total length of 35 cm and 750 g. During collection, the animals were anesthetized with benzocaine, euthanized and dissected for macroscopic evaluation of the organs “in situ”. The gills were fixed in Bouin's solution and stained by the usual Hematoxylin/Eosin method and the alcian blue + PAS technique (Schiff periodic acid). Macroscopically it was observed that the gills were bright red, internally located, protected by the opercula, with numerous spaced traces, filaments and secondary lamellae. Under the light microscopy it was possible to identify the gill’s arteries, cartilaginous structure, pillar cells, respiratory epithelium and mucous cells. We conclude that this species has a gill structure very similar to that of other freshwater teleosts, but more studies are necessary to compare this structure in all phases of its life and different times of the year

    As brânquias se caracterizam por serem órgãos respiratórios de peixes teleósteos, que podem ser parasitados por protozoários dificultando as trocas gasosas. Com este trabalho objetivou-se descrever os danos causados à estrutura tecidual das brânquias de pacu (Piaractus mesopotamicus), durante fase inicial de criação, pelo protozoário Ichthyophthririus multifiliis. Um total de cinquenta alevinos de P. mesopotamicus foi coletado em fevereiro de 2017 em piscicultura comercial, com surto de doença dos pontos brancos. Ao realizar exame microscópio das brânquias observou-se que todos os animais estavam parasitados naturalmente por I. multifiliis. Após análise histológica das brânquias foi possível constatar que havia severas lesões branquiais como congestão, telangiectasia, hemorragia intersticial, edema sub-eptelial, hiperplasia epitelial e de células mucosas e reação inflamatória moderada, localizadas nos filamentos e lamelas sendo frequente a fusão lamelar. No entanto observa-se que as lesões ocasionadas por I. multifilis em brânquias de P. mesopotamicus, são respostas inespecíficas do hospedeiro à agressã

    The objective of this event was to describe all aspects related to the implementation of a demonstration area, at the Federal University of Grande Dourados (UFGD), for organic hay production aiming to provide support in the feeding of beef cattle in the rural communities of Dourados/MS. Therefore, the hay day field demonstration featured information about the forage species for hay production, stages of the haymaking, quality and nutritional value of hay, losses during the haymaking process, the use of hay in animal feeding and economic evaluation of hay utilization. In practice, there was a demonstration of the steps of haymaking: implantation, mowing, tedding of the green forage, raking, baling and storage. A horizontal baler was used to bale the hay, and it was coupled to the tractor. The laboratory analysis was performed to serve as a database to producers and other interested parties. The event was publicized through verbal contact, posters, and distribution of folders at strategic locations. The field day provided a theoretical-practical demonstration of the processes of haymaking, with the participation of rural producers, settlers, quilombolas and students from several courses. Overall, the event meet the knowledge needs of the public, as well as providing knowledge about organic management

    Introduction: Cleft lip and palate is a congenital malformation resulting from the inadequate fusion of bony structures during embryonic development. The etiology is multifactorial, involving genetic and environmental factors. Methodology: This study constitutes a descriptive epidemiological analysis focusing on the investigation of cases of live births with cleft lip and palate in Brazil. Data collection will be conducted through the Live Birth Information System (SINASC) during the period from 2017 to 2021. Results: The gender distribution of live births with cleft lip and palate indicates a male predominance in the sample, representing approximately 58.49% (n=4,390) of the total. Meanwhile, the percentage of female individuals is approximately 41.01% (n=3,078). The category "Unknown" has a very small representation, accounting for only 0.51% (n=38) of the sample. Conclusion: It is observed that live births with cleft lip and palate should not be overlooked. There is a significant number of cases each year, necessitating further related studies to provide solutions in society that directly benefit those affected.Introdução: A fenda labial e palatina é uma malformação congênita resultante da não fusão das estruturas ósseas adequadas durante o desenvolvimento embrionário.

    Understanding the relation between Zika virus infection during pregnancy and adverse fetal, infant and child outcomes: a protocol for a systematic review and individual participant data meta-analysis of longitudinal studies of pregnant women and their infants and children

    Get PDF
    IntroductionZika virus (ZIKV) infection during pregnancy is a known cause of microcephaly and other congenital and developmental anomalies. In the absence of a ZIKV vaccine or prophylactics, principal investigators (PIs) and international leaders in ZIKV research have formed the ZIKV Individual Participant Data (IPD) Consortium to identify, collect and synthesise IPD from longitudinal studies of pregnant women that measure ZIKV infection during pregnancy and fetal, infant or child outcomes.Methods and analysisWe will identify eligible studies through the ZIKV IPD Consortium membership and a systematic review and invite study PIs to participate in the IPD meta-analysis (IPD-MA). We will use the combined dataset to estimate the relative and absolute risk of congenital Zika syndrome (CZS), including microcephaly and late symptomatic congenital infections; identify and explore sources of heterogeneity in those estimates and develop and validate a risk prediction model to identify the pregnancies at the highest risk of CZS or adverse developmental outcomes. The variable accuracy of diagnostic assays and differences in exposure and outcome definitions means that included studies will have a higher level of systematic variability, a component of measurement error, than an IPD-MA of studies of an established pathogen. We will use expert testimony, existing internal and external diagnostic accuracy validation studies and laboratory external quality assessments to inform the distribution of measurement error in our models. We will apply both Bayesian and frequentist methods to directly account for these and other sources of uncertainty.Ethics and disseminationThe IPD-MA was deemed exempt from ethical review. We will convene a group of patient advocates to evaluate the ethical implications and utility of the risk stratification tool. Findings from these analyses will be shared via national and international conferences and through publication in open access, peer-reviewed journals.Trial registration numberPROSPERO International prospective register of systematic reviews (CRD42017068915).</jats:sec

    Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

    Get PDF
    Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

    ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

    Get PDF
    Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

    Four steers in individual paddocks with Marandu grass (B. Brizantha) in 4x4 square design were used to evaluate sunflower crushed supplementation in pasture-grazing animals on nitrogen balance and microbial protein synthesis. Supplements at 6 g kg-1 body weight comprised corn, soybean meal, and mineral and soybean meal substituted at proportions 0, 20, 40 and 60%. Diet contained averages 6.79, 6.96, 7.10 and 6.87% nitrogen respectively for substitution levels 0, 20, 40 and 60%. The inclusion of sunflower crushed (SC) increased nitrogen intake and fecal excretion of nitrogen while providing a positive balance. Animals’ plasma urea concentration supplemented with SC was 28.13% lower than that of supplemented animals without SC. SC inclusion did not change allantoin concentration, purine derivatives, microbial nitrogen, crude microbial protein and microbial efficiency microbial, with mean rates totaling 150.98 mmol day-1; 158.06 mmol day-1, 112.35 g day-1, 702.18 g day-1; 146.41 crude protein (CP) microbial kg-1 of TDN.

    O Programa de Aquisição de Alimentos (PAA), implantado pelo Governo Federal em 2003, é desenvolvido com recursos interministerial do Ministério de Desenvolvimento Social e Combate à Fome (MDS) e do Ministério do Desenvolvimento Agrário (MDA), e operacionalizado da Companhia Nacional de Abastecimento (CONAB). Suas diretrizes buscam garantir a manutenção de estoques reguladores estratégicos, a fim de impedir desabastecimento no país. Todavia, seu principal objetivo é garantir o acesso a alimentos em quantidades necessárias às populações em situação de insegurança alimentar e nutricional por meio da compra da produção da agricultura familiar e doação simultânea. Assim, o PAA Compra com Doação Simultânea (PAA/CDS), veio a atender reivindicações dos movimentos sociais do campo de uma política pública de comercialização que garantisse o fortalecimento socioeconômico na agricultura familiar, com vistas à soberania alimentar. Portanto, é objetivo desta pesquisa, destacar a importância do PAA para Agricultura Familiar e produzir dados que possam demonstrar que o programa vem sofrendo por parte da atual gestão do Governo Federal e consequentemente no estado de Mato Grosso do Sul (MS), contingenciamento orçamentário e a diminuição do alcance dos objetivos princípios originários do programa. Logo, coube investigar a atuação operacional do PAA entre 2012 à 2017, particularmente no tocante ao orçamento anual do programa, avanços, limites e desafios. Por fim, conclui-se que o PAA/CDS, tem obtido sucesso em remover gradativamente o entrave da comercialização dos produtos da agricultura familiar, no entanto, o alcance do programa atualmente possui grave limitação orçamentária para ampliação de suas ações em MS
