ABSTRACT OBJECTIVE To establish a microcephaly cut-off size in adults using head circumference as an indirect measure of brain size, as well as to explore factors associated with microcephaly via data mining. METHODS In autopsy studies, head circumference was measured with an inelastic tape placed around the skull. Total brain volume was also directly measured. A linear regression was used to determine the association of head circumference with brain volume and clinical variables. Microcephaly was defined as head circumference that were two standard deviations below the mean of significant clinical variables. We further applied an association rule mining to find rules associating microcephaly with several sociodemographic and clinical variables. RESULTS In our sample of 2,508 adults, the mean head circumference was 55.3 ± 2.7cm. Head circumference was related to height, cerebral volume, and sex (p < 0.001 for all). Microcephaly was present in 4.7% of the sample (n = 119). Out of 34,355 association rules, we found significant relationships between microcephaly and a clinical dementia rating (CDR) > 0.5 with an informant questionnaire on cognitive decline in the elderly (IQCODE) ≥ 3.4 (confidence: 100% and lift: 5.6), between microcephaly and a CDR > 0.5 with age over 70 years (confidence: 42% and lift: 2.4), and microcephaly and males (confidence: 68.1% and lift: 1.3). CONCLUSION Head circumference was related to cerebral volume. Due to its low cost and easy use, head circumference can be used as a screening test for microcephaly, adjusting it for gender and height. Microcephaly was associated with dementia at old age.

Abstract Background Traditionally, the most effective therapy in the prevention of stroke in patients with atrial fibrillation (AF) has been oral anticoagulation with vitamin K inhibitors, particularly warfarin, whose disadvantages and adverse effects have led to their replacement by "direct oral anticoagulants", as factor X inhibitor. Objectives This study aimed to conduct a brief approach on atrial fibrillation (AF) and use of Rivaroxaban, and to comparatively evaluate the prothrombin time / International Normalized Ratio (PT/INR) in patients with AF in use of this oral anticoagulant, depending on the time elapsed between the last administration of the drug and the time of blood sample venipuncture. Methods We evaluated 34 patients with AF in use of Rivaroxaban by using PT / INR, distributed into a subgroup with blood collection time ≤ 12 hours (n = 7) and > 12 hours after the last drug intake (n = 27). Mann-Whitney test was used to compare the groups and p < 0.05 was considered significant. Results An analysis as a function of time between the Rivaroxaban intake and blood collection, revealed that PT / INR suffers the greatest effect up to 12 hours after ingestion of the drug, dropping to levels close to normal in subsequent hours before the next dose. Conclusion We concluded that, in contrast to warfarin, the knowledge of the time interval between drug intake and blood collection from patients taking Rivaroxaban is essential to properly interpret a laboratory test to assess hemostasis, particularly PT and its derivatives.

ABSTRACT Maintaining an adequate water supply is essential to obtain maximum yields in vegetable crops. As such, this study aimed to determine the water requirements (ETc) and crop coefficients (Kc) of arugula grown in a protected environment under subtropical climate conditions. The experiment was conducted in a greenhouse at the Center for Irrigation Technology of the State University of Maringá in Maringá, Paraná state (PR), Brazil. Crop evapotranspiration (ETc) was determined using three constant water table lysimeters and reference evapotranspiration with the Penman-Monteith equation. The total water consumption of the arugula crop was 113.27 mm. The average values obtained for the crop coefficients in the initial, mid- and late-season stages were 1.92, 1.03 and 1.80, respectively.

Abstract Introduction The importance of our study lies in the fact that we have demonstrated the occurrence ofmechanical dysfunction within polypoid tissues, which promotes the development of polyps in the nasal cavity. Objective To change the paradigm of nasal polyposis (NP). In this new conception, the chronic nasal inflammatory process that occurs in response to allergies, to pollution, to changes in the epithelial barrier, or to other factors is merely the trigger of the development of the disease in individuals with a genetic predisposition to an abnormal tissue remodeling process, which leads to a derangement of the mechanical properties of the nasal mucosa and, consequently, allows it to grow unchecked. Data Synthesis We propose a fundamentally new approach to intervening in the pathological process of NP, addressing biomechanical properties, fluid dynamics, and the concept of surface tension. Conclusion The incorporation of biomechanical knowledge into our understanding of NP provides a new perspective to help elucidate the physiology and the pathology of nasal polyps, and new avenues for the treatment and cure of NP.

RESUMO: Os objetivos deste estudo foram determinar taxas de deposição e decomposição de serapilheira em pastagens de Marandu (Urochloa brizantha cv. Marandu) sob a) três formas de suprimento de nitrogênio (N), b) em diferentes estágios de pastejo rotativo e c) comparar a constante de decomposição (‘k’) derivada de “litterbags” com os valores derivados das estimativas de serapilheira existente e depositada (técnica SED). Os três tratamentos de suprimento de N foram: sem ou com adubação nitrogenada (zero ou 150 kg N ha-1 ano-1) ou com a leguminosa Desmodium ovalifolium. Não houve diferenças significativas (p<0,05) entre a serapilheira existente e as taxas de deposição e decomposição da serapilheira entre os três tratamentos de N. A taxa de decomposição da serapilheira foi estimada usando a técnica SED para os 7 dias de pastejo e dois períodos subsequentes de 14 dias em cada ciclo de 35 dias. A taxa de decomposição da serapilheira foi (p<0,05) maior no segundo período de descanso (dias 21 a 35) em 0,089 g g-1 dia-1, do que no período de pastejo (0,038 g g-1 dia-1) e no primeiro período de repouso (0,040 g g-1 dia-1). A meia-vida média da serapilheira foi de 12 dias pela técnica SED, enquanto a estimativa dos “litterbags” foi de 136 dias. Os resultados mostram que as estimativas fornecidas pelos “litterbags” subestimam severamente a decomposição em relação à técnica SED, e preveem um acúmulo de serapilheira a longo prazo que não é observado.

ABSTRACT: The objectives of this study were to determine the rates of plant litter deposition and decomposition in Marandu pastures (Urochloa brizantha cv. Marandu) under a) three forms of nitrogen (N) supply, b) at different stages of rotational grazing and c) to compare the single-exponential decay constant (‘k’) derived from litterbags with values derived from estimates of deposited and existing litter (DEL technique). The three N supply treatments were: without or with N fertilization (zero or 150 kg N ha-1 yr-1) or with the legume Desmodium ovalifolium. There were no significant differences (p<0.05) between existing litter and rates of litter deposition and decomposition between the three N supply treatments. The litter decomposition rate was estimated using the DEL technique for the 7-day grazing periods and two subsequent 14-day periods in each 35-day grazing cycle. The litter decomposition rate was (P<0.05) higher for the second rest period (days 21 to 35) at 0.089 g g-1 day-1, than for the grazing period (0.038 g g-1 day-1) and for the first rest period (0.040 g g-1 day-1). The mean half-life of the litter was 12 days using the DEL technique while the estimate from the litterbags was 136 days. Results showed that estimates provided by litterbags severely underestimate the decomposition in relation to the DEL technique and predict a long-term accumulation of litter which is not observed.

RESUMO A capacidade de compostos antioxidantes presentes em hortaliças prevenir doenças é importante para as indústrias farmacêutica e alimentícia. Somado a isso, o estresse hídrico pode aumentar a capacidade antioxidante já existente em plantas. Baseado nisso, um experimento foi conduzido com o objetivo de avaliar o efeito de diferentes lâminas de irrigação em função da aplicação de selênio, nas características pós-colheita da couve-flor. O delineamento experimental utilizado foi de blocos ao acaso, em esquema fatorial 3 x 2, com quatro repetições. O primeiro fator foi constituído por três manejos da irrigação com déficit hídrico regulado (déficit hídrico regulado severo (50% da ETc), déficit hídrico regulado moderado (75% da ETc) e irrigação completa (100% da ETc), aplicados após o início da formação das inflorescências) e o segundo pela aplicação foliar de selênio (com aplicação e sem aplicação do elemento). A aplicação foliar de selênio proporcionou aumento de produtividade das plantas sob condição de déficit hídrico regulado moderado (75% da ETc) e sem déficit hídrico (100% da ETc). O cultivo sob déficit hídrico regulado moderado (75% da ETc) foi mais adequada por manter a produtividade e elevar a capacidade antioxidante e do teor de compostos fenólicos. A aplicação foliar de selênio aumentou o teor de polifenóis totais sob condição de estresse hídrico. A aplicação de estresse hídrico regulado severo (50% da ETc) proporcionou maior vida de prateleira aos floretes de couve-flor.

ABSTRACT The ability of antioxidant compounds in vegetables to prevent disease is important for the pharmaceutical and food industries. In addition, water stress can enhance the existing antioxidant capacity of plants. As such, this study aimed to assess the effect of different irrigation depths and selenium application on the postharvest characteristics of cauliflower. A randomized block design was used in a 3 x 2 factorial scheme, with four repetitions. The first factor consisted of three irrigation depths with regulated deficit irrigation (RDI): severe (50% ETc) and moderate RDI (75% ETc) and complete irrigation (100% ETc), performed after inflorescence initiation, and the second of foliar spraying of selenium (with and without the element). Selenium application increased cauliflower yield under moderate RDI and no water/drought stress. Moderate RDI was the most effective strategy for maintaining yield and increasing the antioxidant capacity and phenolic compound content of cauliflower. Foliar spraying of selenium raised total polyphenol content under drought stress. Severe RDI extended the shelf life of cauliflower florets.

BACKGROUND Polymyxins are currently used as a “last-line” treatment for multidrug-resistant Gram-negative infections. OBJECTIVES To identify the major mechanisms of resistance to polymyxin and compare the genetic similarity between multi-drug resistant Klebsiella pneumoniae strains recovered from inpatients of public hospitals in the Mid-West of Brazil. METHODS 97 carbapenems non-susceptible K. pneumoniae were studied. β-lactamases (bla OXA-48, bla KPC, bla NDM, bla CTX-M, bla SHV, bla TEM, bla IMP, bla VIM) and mcr-1 to mcr-5 genes were investigated by polymerase chain reaction (PCR). Mutations in chromosomal genes (pmrA, pmrB, phoP, phoQ, and mgrB) were screened by PCR and DNA sequencing. Clonal relatedness was established by using pulsed-field gel electrophoresis and multilocus sequence typing. FINDINGS K. pneumoniae isolates harbored bla KPC (93.3%), bla SHV (86.6%), bla TEM (80.0%), bla CTX-M (60%) genes. Of 15 K. pneumoniae resistant to polymyxin B the authors identified deleterious mutations in pmrB gene, mainly in T157P. None K. pneumoniae presented mcr gene variants. Genetic polymorphism analyses revealed 12 different pulsotypes. MAIN CONCLUSIONS Deleterious mutations in pmrB gene is the main chromosomal target for induction of polymyxin resistance in carbapenem-resistant K. pneumoniae in public hospitals in the Mid-West of Brazil.

Abstract: En | Text: En | PDF: En

The volatile compounds formed by thermal degradation of the carotenoids present in Dunaliella bardawil were investigated by microwave irradiation (MW) and water bath heating (WB) in different conditions of temperature and time using central composite design. Volatiles extraction by solid phase microextraction (SPME) was optimized and performed at 40 °C for 15 minutes, and those in greater amount were quantified by a validated method of gas chromatography coupled to a quadrupole mass spectrometer (GC-qMS). Employing WB, 10, 12 and 120 ng mL-1 of β-cyclocitral, α-ionone e β-ionone, respectively, were obtained between 60 and 87 °C for 30-75 min, while by MW, 5, 5, 50 ng mL-1 were obtained between 75-107 °C for 1.5-2.8 min. Considering the shorter time of MW, it can be concluded that if the time necessary to obtain the best yield by WB is employed in multiple MW cycles, an amount 10 times greater of those compounds would be obtained by MW than by WB. The results suggest a new biotechnology application for the carotenoids of the microalgae of the Dunaliella genus.

ResumoObjetivou-se, com este estudo, avaliar a composição química do pasto de capim marandu consorciado com amendoim forrageiro ou adubado com N e as características das carcaças de bovinos de corte. A pastagem foi manejada sob pastejo rotacionado com lotação contínua, e carga animal variável, utilizando-se 16 novilhos da raça nelore. Na avaliação de produção de matéria seca verde total, foram observadas significâncias estatísticas entre os tratamentos e períodos avaliados, sendo que o tratamento com o consórcio apresentou uma maior média. A variável proteína bruta (PB) apresentou significância entre os tratamentos e períodos avaliados. Os teores de nutrientes digestíveis totais (NDT) e fibras em detergente neutro (FDN) não apresentaram efeito significativo na avaliação da gramínea. Os períodos que apresentaram os menores ganhos médios diários (GMD) foram o quarto e sexto períodos. Para os teores de PB, NDT e FDN da leguminosa, o terceiro período foi o que apresentou as menores médias. Para as variáveis GMD, número de animais por dia (NAD), GPV, a estatística apresentou significância para a interação, sendo que o primeiro período do tratamento com o consórcio apresentou as maiores médias. No tratamento da adubação, as maiores taxas de lotação foram conseguidas nas estações onde ocorreram as adubações químicas. Foi observada significância estatística para a variável conformação na classificação das carcaças. O consórcio do amendoim forrageiro cv. Belmonte pode ser utilizado em substituição à adubação, com 120kg/N/ha, pois garante o mesmo ganho de peso por animal, sem alterar as características comerciais das carcaças.

AbstractThe objective of this study was to evaluate the chemical composition of the pasture Brachiaria Brizantha intercropped with peanut or fertilized with N and carcass characteristics of beef cattle. The pasture was managed under rotational grazing with stocking continues, with variable stocking, using 16 Nellore bulls. In the evaluation of dry matter production total green significance was observed between treatments and periods evaluated, and treatment consortium presented a higher average. The variable crude protein showed significance between treatments and periods. The NDT and FDN had no significant effect on the evaluation of the grass. Periods had lower ADG were the 4th and 6th periods. For the PB, FDN and NDT legume 3rd period showed the lowest averages. For variables GMD, NAD, GPC showed statistical significance for the interaction, and the 1st treatment period consortium submitted the highest averages. In the treatment of the largest fertilizer stocking rates were achieved in stations where chemical fertilization occurred. Statistical significance was observed for the variable conformation carcass classification. The consortium forage peanut cv. Belmonte may be using to replace fertilization with 120kg / N / ha, as it ensures even weight gain per animal, without changing the commercial carcass traits.

A Psicologia Escolar viveu um momento de crítica aos seus moldes tradicionais de atuação - baseados no diagnóstico e tratamento. Atualmente vem sendo priorizadas práticas comprometidas com a qualidade da educação. A presente pesquisa teve como objetivo conhecer práticas de psicólogos que atuam em secretarias de educação em 98 municípios de Minas Gerais. Por meio de questionários e entrevistas, foram buscadas informações sobre a história do serviço, a estrutura e as condições de trabalho, a atuação profissional e a fundamentação teórica adotada. Este artigo baseia-se em duas entrevistas e apresenta a prática de psicólogos que estão em consonância com a Psicologia Escolar Crítica. Considera-se que importantes práticas vêm sendo desenvolvidas no sentido de que a Psicologia contribua para que a escola seja efetivamente espaço de humanização e apropriação do conhecimento, porém é relevante que haja políticas públicas que melhorem as condições de trabalho e ampliem as possibilidades de atuação do psicólogo nas instituições educacionais.

School Psychology has experienced a moment of criticism on patterns of action from mainstream approaches based on diagnostic and treatment. Now, actions compromised with the quality of education have been prioritized. A research was done aiming at knowing psychologists´ practices in municipal departments of education. This research has covered 98 cities from the Brazilian State of Minas Gerais. Questionnaires and interviews were used to search for information about the history of the service; structure and work conditions; professional practices; and theoretical backgrounds. This paper is based on two of those interviews, and presents practices from psychologists that are in consonance with the Critical School Psychology. We identify that important practices have been conducted in the sense that psychology contributes for the school, actually being a space for humanization and knowledge appropriation. However the study also reveals the importance of public policies that improve work conditions and extend possibilities of actions for the psychologist along education.

Foi comparado o julgamento do escore de condição corporal (ECC) com a espessura de gordura subcutânea (EGS) e sua relação com a eficiência reprodutiva de éguas Mangalarga Marchador doadoras de embrião. O experimento foi conduzido com 56 éguas doadoras entre os meses de agosto/08 e abril/09. O ECC foi maior em éguas mais velhas e aumentou com os dias de permanência no experimento. Houve correlação positiva entre peso e tempo de experimento. O peso não foi associado à idade, porém aumentou ao longo do experimento. A EGS na região da cauda e entre a 12ª e 13ª costelas aumentou com a idade e diminuiu com os dias de permanência no experimento. Houve correlação positiva entre EGS e ECC para a cauda e costela. O diâmetro do folículo dominante aumentou ao longo do ciclo estral, e foi menor em éguas com ECC abaixo de 6,5. O diâmetro folicular não foi influenciado pela idade. O diâmetro médio do folículo ovulatório foi 38,43 ± 3,09 mm. A recuperação embrionária não foi afetada pela idade ou ECC, mas foi menor (41%) eméguas que ovularam folículos menores que 40 mm quando comparados às que ovularam folículos maiores que 40 mm (59%). A idade da doadora não foi associada à taxa de gestação dos embriões nas receptoras. A gordura corporal afetou a eficiência reprodutiva das éguas, além disso, a ultrassonografia parece ser essencial para a avaliação precisa e correta do escore de condição corporal.

Body condition scoring (BCS) was compared to an ultrasound subcutaneous fat thickness (SFT) determination in relation to the reproductive efficiency of Mangalarga Marchador embryo donor mares. Fifty six barren mares were studied throughout the 2008/2009 breeding season (August through April) and the experiment was designed in a completely randomized scheme. BCS was higher in older mares and increased with time in the experiment, and there was a positive interaction between weight and time. Weight was not associated with age, but increased throughout the experiment. Tail and rib BCS increased with age, and decreased with time. There was a positive correlation between BCS and tail and rib SFT. The diameter of the dominant follicle increased during the estrous cycle and was smaller for mares with BCS below 6.5. Age did not influence the dominant follicle diameter. The mean ovulatory follicle diameter was 38.43 ± 3.09. Embryo recovery was not affected by age or BCS but was lower (41%, P=0.003) in mares that ovulated follicles smaller than 40mm compared to mares ovulating follicles greater than 40mm (59%). Donor age was not associated with recipient pregnancy rates. Body fat affected the reproductive efficiency in mares, and seems that ultra-sonography may be essential for correct and reliable body condition scoring.

This descriptive and quantitative study identified and analyzed follow-up actions developed by workers of 13 Family Health Teams (FHT) for cancer patients in a city in the Southeast of Brazil. A questionnaire validated by seven experts was applied to 101 workers. The results indicated that 80.2% of workers were aware of the existence of cancer patients in the FHT scope area; 13.9% were aware of the total number of cancer patients; and 63.3% delivered care to these patients; home visits were carried out by 93.1%; and 69% discussed cases during FHT meetings. Emotional support was the most frequent action among those offered by workers to caregivers. As to the joint work developed within the service network, 46.5% reported that there are no counter-referrals. The conclusion is that follow-up is not systematized; there are needs and possibilities within the Family Health Strategy for workers to follow-up with cancer patients and their caregivers.

Se objetivó identificar y analizar las acciones de acompañamiento desarrolladas por los trabajadores de 13 Equipos de Salud de la Familia (ESF), de los pacientes portadores de cáncer en un municipio del Sureste de Brasil. Se trata de un estudio descriptivo con abordaje cuantitativo. Se utilizó un cuestionario validado por siete jueces. Fueron sujetos de la investigación 101 trabajadores. Se verificó que: 80,2% de los trabajadores conocían la presencia de pacientes portadores de cáncer en el área de influencia de la ESF; 13,9% conocían el total de los pacientes, 63,3% realizaban atenciones; la visita domiciliar eran realizadas por 93,1% de los trabajadores y 69,0% realizaban discusiones del caso en reuniones de la ESF; y, el apoyo emocional al cuidador es la acción más frecuente entre aquellas ofrecidas por los trabajadores al cuidador. En relación a la articulación de la red de servicios, 46,5% de los trabajadores refirieron no haber contra referencia. Se concluye que existen necesidades y posibilidades en las ESF para realizar el acompañamiento a estos clientes y a sus cuidadores, siendo que este acompañamiento es realizado de modo no sistematizado.

Uma contribuição fundamental para o estudo da ciclagem de nutrientes no sistema solo/planta/ animal é a avaliação do consumo pelo gado de forragem e dos nutrientes nela contidos. Testaram-se, sob condições controladas, técnicas para avaliar a produção fecal, digestibilidade in vitro, consumo de forragem e a proporção de leguminosa ingerida na dieta. Cinco novilhos de Zebu foram confinados e alimentados com quantidades conhecidas de cinco rações com diferentes proporções de Brachiaria dictyoneura e Desmodium ovalifolium. Todas as fezes bovinas foram recolhidas e pesadas e estes valores foram comparáveis com as estimativas da produção fecal derivadas do uso da técnica de óxido de cromo. A digestibilidade in vitro variou de 7 a 10% acima da digestibilidade in vivo atual. Amostras de fezes de novilhos alimentados com dietas com 25% ou mais de capim na mistura apresentaram abundância de 13C por entre 1,7 e 2,1‰, mas este empobrecimento isotópico não foi observado quando a dieta era com 100% D. ovalifolium. Houve correlação positiva linear (r² = 0,97***) entre δ13C da dieta com o δ13C das fezes, mas o conteúdo de leguminosa foi subestimado em mais de 10% quando a dieta ingerida foi de 100% de leguminosa. Nenhum dos indicadores internos, como o conteúdo de lignina ou cinzas, foram úteis para prever o consumo de forragem, mas os resultados da técnica utilizando óxido crômico como indicador externo foram satisfatórios. A abundância de 13C das fezes foi indicador adequado da proporção da leguminosa na dieta.

A key contribution to study the cycling of nutrients in soil/plant/animal systems is the evaluation of the consumption of forage and their nutrients by cattle. The objective of this study was to test techniques to evaluate faecal production, in vitro digestibility, forage consumption and the proportion of legume in the acquired diet. Five Zebu steer calves were confined and fed five diets of different combinations of Brachiaria dictyoneura and Desmodium ovalifolium. All quantities of faeces were collected per animal and these values were found to compare favourably with those derived from using the chromium oxide technique. In vitro digestibility ranged from 7 to 10% higher than the actual in vivo digestibility. Faecal samples from steers fed with diets with 25% or more of grass in the mixture were found to be depleted in δ13C between 1.7 and 2.1‰, but no depletion was observed when the diet was 100% D. ovalifolium. There was a positive linear regression (r² = 0.97***) of the δ13C of the diet with the δ13C of faeces, but if the acquired diet contained a very high proportion of legume, the legume content could be underestimated by as much as 10%. None of the internal indicators, such as lignin or ash content of the diets, were useful to predict feed intake, but the chromium oxide external indicator performed satisfactorily. The 13C analysis of the faeces was an effective predictor of the proportion of the legume in the consumed diet.
