    Com o objetivo de se obterem informações sobre os sistemas de produção de ovinos e avaliar a frequência de anticorpos contra o vírus da Maedi-Visna (MV) em propriedades localizadas na microrregião de Juazeiro - BA, investigou-se, a partir da aplicação de questionários, algumas características de manejo sanitário, alimentar e reprodutivo em 58 propriedades nos oito municípios que compõem essa região: Juazeiro, Sento Sé, Sobradinho, Pilão Arcado, Campo Alegre de Lourdes, Remanso, Casa Nova e Curaçá. Das propriedades visitadas, 89,6% (81,74% - 97,46%) adotavam sistema extensivo de criação e 58,6% (45,92% - 71,28%) não tinham assistência técnica. O manejo sanitário mostrou-se precário. Os produtores entrevistados apontaram a linfadenite caseosa como uma das doenças mais observadas nos rebanhos. Analisaram-se 919 amostras de soro pelo teste de Imunodifusão em Gel de Agarose (IDGA) no Laboratório de Patologia Clínica da Embrapa Caprinos e Ovinos, em Sobral - CE. Detectaram-se quatro animais positivos. As Lentiviroses de Pequenos Ruminantes têm demonstrado, em diversos estudos, relação direta com os manejos adotados nas propriedades e introdução de tecnologias sem adequado controle sanitário. Acredita-se que o baixo número de ovinos positivos evidenciado neste levantamento deva-se ao baixo índice tecnológico adotado na região. Outra possibilidade é de que, nessa região, o rebanho de ovinos caracteriza-se pela predominância de raças nativas e sem raça definida (SRD), com poucos animais importados de outros estados e/ou países. Production systems of sheep and the occurrence of Maedi-Visna Virus in properties located in the Juazeiro, BA, microregion. Abstract: In order to obtain data from the used sheep production systems and to analyze them to the occurrence of Maedi-Visna in properties located in the microregion of Juazeiro - BA, some features of health, food and reproductive management were inquired from the application of questionnaires, on 58 properties located in the eight municipalities that make up this region: Juazeiro; Sento Sé; Sobradinho; Pilão Arcado; Campo Alegre de Lourdes; Remanso; Casa Nova and Curaçá. This survey evaluated some basic elements in the production chain. It was asserted that 89.6% (81.74% - 97.46%) of the producers raise their animals extensively and 58.6% (45.92% - 71.28%) have no technical assistance. The health management seemed to be precarious. Caseous lymphadenitis is one of most commonly diseases observed by farmers. 919 samples of sheep serum were collected and analyzed by AGID in the Laboratory of Clinical Pathology of Embrapa Goats, in Sobral - CE. Four animals were positive. The Lentivirus of Small Ruminants has been shown in several studies to be directly related to the management practices adopted on the properties. It is believed the low number of positive sheep found in this survey is related to the low technological level used in this region. Another possibility is that the regional sheep herd is predominantly made up of native or mixed breed

    INTRODUCTION AND AIMS: Splenic marginal zone lymphoma, an uncommon subtype of non-Hodgkin lymphoma (NHL), is usually present with symptomatic splenomegaly. Although splenectomy has long been considered the first-line therapy in symptomatic or cytopenic patients, it can lead to significant morbidity and mortality. Splenic irradiation is an option for patients who have a poor response to systemic therapy and/or are not surgical candidates. In this paper, we present a case report of a patient who received splenic radiotherapy for symptomatic splenomegaly. METHODS: An 85-year-old Caucasian man with a 4 year history of low-grade NHL presented with progressive pancytopenia, significant weight loss and symptomatic splenomegaly (abdominal discomfort, sense of fullness and limitation of mobility due to spleen size). The patient refused splenectomy and, in December 2017, was referred to palliative splenic radiotherapy. He was initially treated with five fractions of one Grey (Gy) in order to evaluate clinical and haematology response. After that, 1.5 Gy daily, 5 days a week for 3 weeks. 3D conformal radiotherapy, multiple fields and mixed energy (6 and 15 Mv) were used. RESULTS: Radiotherapy allowed significant splenic reduction to almost half the size, resolving abdominal discomfort and improving quality of life. There was no decline of haemoglobin, leukocytes and platelet counts; in fact, there was a marginal increase. CONCLUSION: Palliative splenic irradiation was well tolerated confirming that it is a safe treatment option for palliation of symptomatic splenomegaly. Thereby, splenic irradiation should be strongly considered in the management of symptomatic splenomegaly, for selected patients who are refractory to or unsuitable for other options or when the patient refuses other treatments.info:eu-repo/semantics/publishedVersio

    A ovinocultura no Nordeste brasileiro se destaca pela grande relevância sócio-econômica, representando muitas vezes a principal fonte de renda para as famílias no semiárido. Com o objetivo de se obter informações sobre os sistemas de produção de ovinos em propriedades localizadas na Região do Baixo Médio São Francisco (Microrregião de Juazeiro), estado da Bahia, investigou-se a partir da aplicação de questionários, algumas características de manejo sanitário, alimentar e reprodutivo de 58 propriedades localizadas nos oito municípios que compõem esta região: Juazeiro, Sento Sé, Sobradinho, Pilão Arcado, Campo Alegre de Lourdes, Remanso, Casa Nova e Curaçá. Estes municípios possuem uma das maiores concentrações de ovinos do país. O tipo de exploração predominante foi o extensivo, com presença de animais nativos, mestiços e sem raça definida, visando a produção de carne e pele, com baixa produtividade e tecnificação. O manejo sanitário mostrou-se precário

    A introdução de novas raças, com o objetivo de aumentar a produtividade, levou à alteração do perfil sanitário dos rebanhos. Dentre as enfermidades introduzidas no Brasil, destacam-se as lentiviroses de pequenos ruminantes (LVPR), representadas pela artrite-encefalite caprina (CAE) e pela maedi-visna (MV). Devido à importância econômica da ovinocultura para a microrregião de Juazeiro-Bahia e à escassez de dados sobre a lentivirose em ovinos, buscou-se obter a prevalência da MV. Foram avaliados 919 soros por imunodifusão em gel de ágar (IDGA). As amostras foram colhidas nos oito municípios que compõem essa microrregião (Juazeiro, Sento Sé, Sobradinho, Pilão Arcado, Campo Alegre de Lourdes, Remanso, Casa Nova e Curaçá), conforme a representatividade de cada município no total de animais. Constatou-se que 0,34% (4/919) dos ovinos amostrados apresentaram reação positiva no IDGA. Concluiu-se com esse resultado que a MV ocorre na microrregião estudada, com baixa prevalência, provavelmente pela predominância de animais de raças localmente adaptadas. SEROLOGICAL PREVALENCE OF MAEDI VISNA IN SHEEP HERDS IN THE MICROREGION OF JUAZEIRO - BAHIA, BYAGAR GEL IMMUNODIFFUSION (AGID). The introduction of new breeds, aiming at increasing productivity, caused the change in the health profile of herds. Among the diseases introduced in Brazil lentiviroses of small ruminants (LVPR) stand out, represented by caprine arthritis encephalitis (CAE) and the maedi-visna (MV). In order to obtain data concerning the presence of maedi visna (MV) in sheep herds in the microregion of Juazeiro, Bahia, 91 9 serum samples were evaluated by agar gel immunodiffusion (AGID). The samples were collected in eight cities that make up this microregion (Juazeiro, Sento Sé, Sobradinho, Pilão Arcado, Campo Alegre Lourdes, Remanso, Casa Nova and Curaçá) considering how representative each municipality is within the totalilty of animals. It was observed that 0.34% of the sampled sheep showed positive reaction in the AGID. It was concluded that the MV occurs with low prevalence in the studied microregion, probably due to the predominance of locally adapted breeds

    Brazelton Neonatal Behavioral Assessment Scale: a psychometric study in a Portuguese sample

    Get PDF
    Background: The Neonatal Behavioral Assessment Scale (NBAS, Brazelton & Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982). Objective: Examine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants. Method: The NBAS was performed in the first week of infant life (3 days±2) and in the seventh week of life (52 days±5). Results: Principal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants. Conclusion: Changes in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale.Financed by the Operational Program Science and Innovation 2010 (POCI 2010) of the III Community Support and co-financed by the European Community Found FEDER (POCI/SAU-ESP/56397/2004; Anxiety and depression in women and men in the transition to parenthood: Effects on fetal and neonatal development and behaviour) and under a FCT PhD Grant (SFRH/BD/18249/2004)

    An application to enrich the study of auditory emotion recognition

    Get PDF
    The ability to recognize emotions in spoken words is central in human communication and social relationships. When studying one's ability to perceive emotions, the standard paradigm is to have listeners choose which one of several emotion words best characterizes linguistically neutral utterances made by actors attempting to portray various emotional states. Usually, generic experiment control software are used, which may present several limitations. In this paper we present a novel approach to the problem, based on a mobile application that can be easily configured by the researcher to set up the desired protocol. This approach not only facilitates and improves study design and data collection, but also provides a plethora of new variables about the participants that, to the best of our knowledge, have never been considered before in this domain, including behavioural research.This work has been supported by COMPETE: POCI-01-0145-FEDER-007043 and FCT - Fundacao para a Ciencia e Tecnologia under projects UID/CEC/00319/2013 and PTDC/MHN-PCN/3606/2012.info:eu-repo/semantics/publishedVersio

    Molecular marks in the study of genetic distance between local goats groups of northwest: I. DNA samples. Abstract - The groups of Brazilians goat of northeast are originally of units brought at the time of settling and had differentiated geenotipicaly due to the geographic isolation. The genetic groups MoxotÛ and Canindé had been homologated as distinct breed. Even so some authors support, under the historical point of view, that goat presented only diverse color coat pattern, but with a same genetic origin. To investigate the diversity and genetic distance of similar coat color pattern, this work harvested samples of the main destined flocks the conservation of genetic resources of Researchs Institutes in the Cear·, PiauÌ and Bahia. The samples of blood are stored in the Embrapa Caprinos and Embrapa Meio-Norte laboratories. Until the moment, 100 samples of the MoxotÛ breed had been sampled, 32 of the CanindÈ breed, 152 of the Marota breed, 45 of Azul breed and the 37 of the Repartida one. The samples of blood of 25 MoxotÛ, 25 Marota breed and 10 Azul breed has been extracted by the protocol of phenol. The markers investigated until the moment are the INRA006, INRA172, CSRC 0247 and ILSTS011. The data observed had been not yet analyze
