Resumo: A região do MATOPIBA, formada pelos municípios fronteiriços dos estados do Maranhão (MA), Tocantins (TO), Piauí (PI) e Bahia (BA), é apontada na literatura como a última fronteira agrícola do país, resultante do avanço do agronegócio e do crescimento de um modelo de produção apoiado em alta mecanização. Nesse sentido, o objetivo deste estudo é analisar a situação da modernização agrícola dessa extensão geográfica no ano de 2017. Para isso, as metodologias empregadas consistem na aplicação da Análise Fatorial (AF), Análise Exploratória de Dados Espaciais (AEDE) e na estimação do modelo espacial SAC, tendo como variável dependente o Produto Interno Bruto (PIB) agropecuário e como variáveis independentes os fatores obtidos pela AF. Os resultados encontrados indicaram a presença de sete fatores; e apenas o intensivo em capitalização da atividade agrícola (F1), intensivo em exploração do fator terra (F2) e intensivo em máquinas e implementos agrícolas tradicionais (F3) foram estatisticamente significantes. Portanto, é possível concluir que foi identificada a concentração de alguns fatores em determinadas áreas e que a região precisa de maiores investimentos para que possa se consolidar como uma fronteira agrícola.

Abstract: The MATOPIBA region, formed by the border municipalities of the states of Maranhão (MA), Tocantins (TO), Piauí (PI) and Bahia (BA), is identified in the literature as the last agricultural frontier in the country, resulting from the advance of agribusiness and of the growth of a production model supported by high mechanization. In this sense, the objective of this study is to analyze the situation of agricultural modernization of this geographic extension in the year 2017. For this, the methodologies used consist of the application of Factor Analysis (FA), Exploratory Analysis of Spatial Data (AEDE) and the estimation of the SAC spatial model, having the agricultural Gross Domestic Product (GDP) as the dependent variable and the factors as independent variables obtained by AF. The results found indicated the presence of seven factors; and only the intensive in capitalization of agricultural activity (F1), intensive in exploitation of the land factor (F2) and intensive in traditional agricultural machinery and implements (F3) were statistically significant. Therefore, it is possible to conclude that the concentration of some factors was identified in certain areas and that the region needs greater investments so that it can consolidate itself as an agricultural frontier.

ABSTRACT Irregular rainfall and the occurrence of droughts in tropical semi-arid regions have a negative impact on the quality and availability of water stored in reservoirs. The aim of this study was to evaluate the quality of water stored in an artificial reservoir in the tropical semi-arid region of Brazil during years of drought. The study area was the Pereira de Miranda reservoir, located in the district of Pentecoste, Ceará, Brazil. Seven water-sampling campaigns were carried out between April 2015 and September 2016. The variables to be analysed were chlorophyll-a (Cl-a), hydrogen potential (pH), electrical conductivity (EC), total nitrogen (Ntotal), total phosphorus (Ptotal), transparency (SD), fixed/volatile/total suspended solids (FSS/VSS/TSS), and temperature (T0); the trophic state index (TSI) was then calculated. The variables which better explained the variance in water quality were identified by principal component analysis (PCA). The waters of the Pereira de Miranda reservoir were classified as hyper-eutrophic throughout the study period and at each of the collection points. The PCA identified that the variability in water quality was determined by suspended sediment and nutrients, showing that the reduction in variables made it possible to obtain high explainability of the conditions of the reservoir during monitoring, saving time and resources on the analyses. In addition, the occurrence of severe drought resulted in low accumulated volumes, which intensified and made vulnerable the quality of the waters. As such, the Pereira de Miranda reservoir proved to be in a process of degradation, mainly due to anthropogenic action, intensified by climate factors.

ABSTRACT Purpose: This study aimed to assess the necessity of routine intraoperative cell salvage in liver transplantations. Methods: A total of 327 liver transplants performed between 2014 and 2016 was included in the analysis. Patient data, including pre-transplant examinations, intraoperative red blood cell transfusions, and procedural information, were collected. Results: The median age of the patients was 54 years old, with 67% (219) being male. The most prevalent ABO blood type was O, accounting for 48% (155) of cases. The leading causes of liver disease were hepatitis C (113 cases, 34.6%) and alcohol-related liver disease (97 cases, 29.7%). Out of the 327 liver transplants, allogeneic red blood cell transfusions were administered in 110 cases (34%) with a median of two units of red blood cells per case. Cell salvage was employed in 237 transplants (73%), and successful blood recovery was achieved in 221 cases (93%). Among the group that recovered more than 200 mL of blood, the median volume of recovered blood was 417 mL, with no transfusion of allogeneic blood required. A total of 90 transplants was performed without utilizing cell salvage, and, among these cases, 19 required blood transfusions, with a median of zero units transfused. Conclusions: This study suggests that routine cell salvage is unnecessary for all liver transplantations. The most suitable indication for its use is in patients presenting with portal vein thrombosis and abnormal creatinine levels.

Abstract: COVID-19 rapidly spread across the world in an unprecedented outbreak with a massive number of infected and fatalities. The pandemic was heavily discussed and searched on the internet, which generated big amounts of data related to it. This led to the possibility of attempting to forecast coronavirus indicators using the internet data. For this study, Google Trends statistics for 124 selected search terms related to pandemic were used in an attempt to find which keywords had the best Spearman correlations with a lag, as well as a forecasting model. It was found that keywords related to coronavirus testing among some others, such as “I have contracted covid”, had high correlations (≥0.7) with few weeks of lag (≤4 weeks). Besides that, the ARIMAX model using those keywords had promising results in predicting the increase or decrease of epidemiological indicators, although it was not able to predict their exact values. Thus, we found that Google Trends data may be useful for predicting outbreaks of coronavirus a few weeks before they happen, and may be used as an auxiliary tool in monitoring and forecasting the disease in Brazil.

Abstract Effects were assessed of the dilutants TRIS and ACP - 101c® with the addition of different guinea fowl (Numida meleagris) egg yolk concentrations. Fifteen ejaculates were collected from five goats of the Anglo Nubian breed. The ejaculates were pooled and then divided into 12 groups, two control groups (GC1 TRIS, with 2.5% Gallus gallus domesticus hen egg yolk GOGD), (GC2 Control Group ACP - 101c®, with the addition of 2.5% Gallus gallus domesticus hen egg yolk GOGD) and ten experimental groups (EG), containing TRIS and ACP added with different concentrations of egg yolk from guinea hen (Numida meleagris) (TRIS 2,5% GONM; TRIS 5% GONM; TRIS 10% GONM; TRIS 15% GONM; TRIS 20% GONM; ACP® 2,5% GONM; ACP® 5% GONM; ACP® 10% GONM; ACP® 15% GONM; ACP® 20% GONM). Then cryopreservation was carried out and the samples stored in liquid nitrogen (-196 °C). After seven days, the samples were thawed and assessed for spermatic kinetics, immunofluorescence and sperm morphology. Analysis of GOMN by the CASA system showed that the various parameters were similar to those of GOGD (P>0.05). The membrane integrity, mitochondrial potential and the acrosome were not influenced by the treatment (P>0.05) nor by the dilutant used for cryopreservation (P>0.05). The spermatic morphology was also preserved by the different GOGD and GONM concentrations in the ACP® and TRIS dilutants, with no statistically significant differences (P<0.05). It was concluded that Numida meleagris egg yolk, as external membrane cryoproctant added to the dilutants ACP-101c® and TRIS, improved goat semen quality.

ABSTRACT Toxoplasmosis is a zoonosis of reproductive nature that is transmitted to humans mainly by ingestion of undercooked meat or drinking oocyte-contaminated water. The slaughter of small ruminants in clandestine slaughterhouses and the presence of companion animals in these locations may be epidemiologically important for the dissemination of the disease. The objective of the present study was to determine toxoplasmosis prevalence by researching anti- Toxoplasma gondii antibodies in meat sheep herds from farms in Teresina microregion, Piauí, Brazil. A total of 450 blood samples were collected from sheep of both sexes, belonging to 28 herds from the 14 municipalities that comprise the microregion. The samples were analyzed by the enzyme-linked immunosorbent assay (ELISA), and the presence of anti-T. gondii antibodies was observed in 62% (279/450) of the animals in all the municipalities and on at least one farm in each municipality. The high occurrence of positive animals is an indication of reproductive problems in these herds, characterizing a problem for both sheep rearing and public health.

RESUMO: Dentre as enfermidades que acometem o sistema reprodutivo dos animais domésticos, a brucelose na espécie ovina tem se destacado por gerar prejuízos econômicos significativos à ovinocultura. Dessa forma, apresenta-se como uma ameaça ao crescimento e à produtividade dos rebanhos ovinos. Diante de tal problemática, objetivou-se, por meio desta pesquisa, identificar a prevalência de brucelose ovina em rebanhos pertencentes a municípios da microrregião de Teresina, Piauí, por meio dos testes sorológicos, imunodifusão em gel de ágar (IDGA) e ensaio imunoenzimático (ELISA) indireto. Quatorze municípios foram incluídos na pesquisa. Para sua execução, colheram-se, por punção venosa da jugular, amostras sanguíneas de 521 animais púberes. Após colheita, as amostras foram submetidas às técnicas sorológicas, IDGA e ELISA indireto, para a detecção de anticorpos anti-B. ovis. Das 521 amostras submetidas ao teste de IDGA, 23 (4,41%) foram sororreagentes e 498 (95,58%) negativas. Quanto ao teste ELISA indireto, obtiveram-se 24 (4,61%) amostras suspeitas e 497 (95,39%) amostras negativas, não havendo animais reagentes neste teste, apenas suspeitos. A soroprevalência da brucelose ovina na microrregião homogênea de Teresina, Piauí, foi de 4,41%. Assim, foi possível identificar ovinos com sorologia reagente à infecção por B. ovis, presente em municípios do estado do Piauí. Além disso, a IDGA mostrou-se mais sensível em detectar animais que tiveram contato com o agente etiológico da doença.

ABSTRACT: Among the diseases that affect the reproductive system of domestic animals, brucellosis in the sheep species is important because it generates significant economic losses to sheep rearing. Thus, it is a threat to the growth and productivity of sheep herds. In the face of this problem, the objective of the present research was to identify the prevalence of ovine brucellosis in herds in municipalities of the Teresina, Piauí, Brazil microregion by using the agar gel immunodiffusion assay (AGID) and indirect enzyme-linked immunosorbent assay (ELISA) serological tests. Fourteen municipalities were included in the research. Blood samples were collected from 521 pubescent animals by puncturing the jugular vein. After collection, the samples were submitted to the serological techniques, AGID and indirect ELISA, to detect anti B. ovis antibody. Of the 521 samples submitted to the AGIDtest, 23 (4.41%) were sera reagent and 498 (95.58%) negative. The indirect ELISA tests, 24 (4.61%) suspect samples and 497 (95.39%) negative samples were obtained, and there were no reagent animals in this test, only suspect. The seroprevalence of ovine brucellosis in the Teresina, Piauí microregion was 4.41%. Thus, it is possible to identify sheep with reagent serology to infection by B. ovis, that is present in municipalities in the state of Piauí, Brazil. Furthermore, AGIDwas shown to be more sensitive in detecting animals that had had contact with the etiological agent of the disease.

Abstract INTRODUCTION: Leishmaniasis, a disease caused by a parasite endemic to large areas of tropical and subtropical countries, is a growing public health problem. METHODS: Male BALB/c mice were infected with Leishmania amazonensis and treated with extracts isolated from Annona mucosa. RESULTS: Treated groups had significantly reduced footpad swelling. The group treated intraperitoneally with hexane extract showed footpad swelling similar to groups treated with Pentamidine® and Glucantime®. Groups treated with dichloromethane extract and hexane extract presented the recovering phenotype associated with reduced parasite levels. CONCLUSIONS: Extracts of A. mucosa are promising sources of novel antileishmanial compounds.

RESUMO: Lentivírus de pequenos ruminantes (LV) é o termo genérico utilizado para designar os vírus da artrite encefalite caprina e Maedi-Visna, os quais pertencem à família Retroviridae, subfamília Orthoretrovirinae, gênero Lentivirus. Tais vírus infectam caprinos e ovinos, causando enfermidades de curso lento com lesões inflamatórias, crônicas e degenerativas que podem atingir vários órgãos, provocando caquexia e morte. Os animais infectados eliminam o vírus sobretudo por meio de secreções e excreções e transmitem-no especialmente em situações de estreito contato. Não há tratamento até o momento. O controle é baseado na criação segregada, no manejo e no sacrifício dos positivos. Esse agente infeccioso já foi relatado em várias partes do mundo, sendo responsável por perdas econômicas significativas. Por o agente ter sido verificado em vários estados do Brasil e por não existirem dados soroepidemiológicos nas mesorregiões sudeste e sudoeste piauiense, esta pesquisa teve por objetivo realizar inquérito sorológico para investigar a ocorrência de anticorpos para o LV em ovinos e caprinos nas microrregiões do Alto Médio Canindé, Picos e Floriano, no Piauí. Para tanto, foram coletadas 1.280 e 1.360 amostras de soro caprino e ovino, respectivamente, oriundos de 20 municípios, distribuídos nas três microrregiões, sendo o número de amostras proporcional ao rebanho efetivo de cada município. As amostras de soro foram analisadas utilizando o teste de imunodifusão em gel de agarose (IDGA). Nenhum dos soros pesquisados reagiu positivamente, constatando-se soroprevalência nula. Ressalta-se a importância da implantação de um rigoroso programa de controle para que se possa evitar a introdução e/ou a disseminação desse agente infeccioso nessas microrregiões.

ABSTRACT: Small ruminant lentiviruses (LV) is the generic term for the caprine arthritis-encephalitis and Maedi-Visna viruses, which belong to the Retroviridae family, Orthoretrovirinae subfamily, Lentivirus genus. The virus infects goats and sheep, causing slow course of disease with inflammatory, chronic and degenerative lesions, which can reach several organs, provoking cachexia and death. Infected animals eliminate the virus mainly through secretions and excretions and transmit it especially in close contact situations. There is no treatment to date. The control is based on segregated creation, management and sacrifice of the positive. This infectious agent has been reported in various parts of the world and is responsible for significant economic losses. It was verified in several states of Brazil and there are seroepidemiological data in southeast and southwest mesoregions of Piauí, Brazil. This research aimed to perform serological survey to investigate the occurrence of antibodies to LV in sheep and goats, in the regions of Alto Médio Canindé, Picos and Floriano. So, 1,280 and 1,360 serum goats and sheep samples, respectively, were collected, coming from 20 municipalities, distributed in the 3 microregions. The number of samples was proportional to the actual herd of each municipality. The samples were analyzed using the agar gel immunodiffusion test. None of the surveyed sera reacted positively, though there is a null seroprevalence. It was emphasized the importance of implementing a rigorous control program in order to prevent the introduction and spread of this infectious agent in these microregions.

A fasciíte nodular é um tumor benigno, decorrente da proliferação reativa de células fibroblásticas ou miofibroblásticas. Pode ser confundida com os sarcomas, devido a seu rápido crescimento e rica celularidade. Apesar da possibilidade da involução espontânea, a excisão é o tratamento de escolha. É apresentada uma paciente de 24 anos, com um nódulo de 3 meses de evolução na região zigomática. Foi realizada biópsia excisional. O exame histopatológico associado à imuno-histoquímica com os marcadores HHF35, AML e Ki-67 permitiram a confirmação diagnóstica. A principal relevância do caso apresentado é sua rara localização, sugerindo a sua inclusão entre os diagnósticos diferenciais das lesões tumorais na face.

Nodular fasciitis is a benign tumor, resulting from reactive proliferation composed of fibroblastic/myofibroblastic cells. Due to its rapid growth and high cellularity it may be mistaken for sarcoma. Despite the possibility of spontaneous regression, excision is the treatment of choice. A 24-year-old female patient presented with a nodule on the zygomatic region with 3 months of evolution. Excisional biopsy was performed. Histopathological examination associated with immunohistochemical markers HHF35, AML and Ki-67 allowed diagnostic confirmation. The main relevance of the case presented is its rare location, suggesting its inclusion among the differential diagnoses of tumor lesions on the face.

We investigated antioxidant capacity, phenolic content and phytotoxic effects in seven species of fruit native to Brazil: Acrocomia aculeata, Hymenaea stigonocarpa, Tamarindus indica, Byrsonima intermedia, Psidium firmum, Myrciaria cauliflora and Ficus obtusifolia. Phytotoxic effects were assessed from crude ethanol extracts and semipurified fractions. In four of the seven fruits, total phenolic content, as determined by Folin-Ciocalteu assay, was higher in the peel than in the pulp. We found that total phenolic content correlated significantly with antioxidant capacity. High-performance liquid chromatography with diode array detection revealed the presence of the flavonoids quercetin and rutin in some fruits. We also evaluated the allelopathic effects of the crude ethanol extract and semipurified fractions. In most of the essays, the ethyl acetate fractions showed the highest level of activity.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

As regiões malarígenas da Amazônia brasileira têm se caracterizado por dificuldades no acesso ao tratamento e não aceitação das drogas pelos doentes. Com objetivos de avaliar a eficácia da cloroquina em dose simples de 600 mg, os autores realizaram um ensaio clínico duplo cego, placebo controlado em 132 pacientes portadores de malária por P. vivax. Os pacientes foram distribuídos em dois grupos: grupo CPLA que recebia 600 mg de cloroquina em dose simples no primeiro dia de tratamento e duas doses de placebo no segundo e terceiro dias de tratamento. Grupo CLO que recebia 600 mg de cloroquina no primeiro dia e 450 mg no segundo e terceiro dias. A média geométrica da densidade parasitária durante o seguimento foi similar em ambos os grupos. Não houve diferenças de cura parasitológica em ambos os grupos (p = 0,442). Observou-se eficácia clínica e parasitológica nos indivíduos que receberam dose simples de cloroquina, indicando a possibilidade de uso restrito a algumas áreas da Amazônia brasileira, contudo, a resposta inadequada de três pacientes sugere a necessidade de outros estudos.

Malaria regions of the Amazon basin have been characterized by difficult access and non-compliance of the patients to treatment. In an attempt to assess the schizonticide efficacy of chloroquine in a single dose of 600 mg, the authors realized a double-blind, placebo-controlled trial in 132 outpatients with vivax malaria. Patients were distributed into two groups: group CPLA, given chloroquine 600 mg (single dose) on the first day of treatment, and two doses of placebo on second and third days. Group CHLO, given chloroquine 600 mg on first day and 450 mg on second and third day. Geometric means of the parasite density during the follow-up was similar in both groups. No differences were observed in the parasitological cure between the two groups (p = 0.442). There was clinical and parasitological efficacy in treatment of patients given a single-dose of chloroquine. This suggests that its restricted use could be indicated in remote areas of Brazilian Amazon Region, nevertheless the inadequate response of three patients indicates the need for further studies.
