Abstract Objective Children with spina bifida (SB) are at risk for stunting and overweight. However, height and Body Mass Index (BMI) z-score distribution in children and adolescents with SB are unclear. The aim of this study was to examine height and BMI z-score distribution in Brazilian children and adolescents with and without SB. This study further aimed to examine whether height and BMI z-scores differ between individuals with and without SB. Method This study included 101 participants (SB: n= 18; non-SB: n= 83, aged 7-16 years). The World Health Organization (WHO) AnthroPlus software was used to calculate height and BMI z-scores. AnthroPlus z-score distribution graphs were used to examine individual z-scores based on the 2007 WHO normal distribution curve. Effects of the group (SB vs non-SB) on height and BMI z-scores were examined with sequential regression. Results In the WHO distribution graph analysis, height z-scores of participants with SB were slightly left-shifted compared to the WHO normal distribution curve. In the regression analysis, group (SB vs non-SB) was a significant predictor of height z-scores after controlling for sex and age (ΔR2= 0.064, p= 0.010). BMI z-scores of participants with SB were right-shifted compared to the WHO normal curve. However, there was no contribution of the group to BMI z-scores (ΔR2= 0.011, p= 0.301). Conclusions These findings suggest that Brazilian children and adolescents with SB may be at risk for reduced height and increased BMI.

Abstract The aim was to associate living, health and oral health conditions with the quality of life (QL) of children and adolescents (CA) with sickle cell disease (SCD). Of the 120 eligible users of a public hematological service, 106 CA with SCD from 6 to 18 years of age, and their caregivers, answered semi-structured questions about socio-demographic, health and oral health conditions. For QL, we used the validated instrument PedsQLSCD™. The oral clinical examination occurred according to the guidelines of WHO and SB Brazil 2010. The majority of CA were non-white people (88%), mean age of 10.4 (±2.9) years, family income of up to two monthly minimum wages, for 03 to 05 members, with diagnosis of sickle cell anemia by neonatal screening, hospitalizations were due allergic crises, polypharmacy and dental caries (51%) were present. “About the Impact of My Pain” was the best-fit model for the QLSCD (adjusted R²=56%; AIC=28.67; p=0.04). Dental caries in permanent dentition worsened the QLSCD (OR=0.53; IC95%=0.35-0.78; p<0.05) and was associated with the type of school, car ownership, number of family members, of complications and of the medications. To overcome this scenario, programmatic actions are required, and implementation of public policies specifically directed towards these groups.

Resumo Objetivou-se associar condições de vida, de saúde e de saúde bucal à qualidade de vida (QLV) de crianças e adolescentes (CA) com Doença Falciforme (DF). Dos 120 usuários elegíveis de um serviço público hematológico, 106 CA entre 6 e 18 anos de idade, e seus cuidadores, responderam questões semiestruturadas sobre condições sociodemográficas, de saúde e saúde bucal. Para a QLV, o instrumento validado PedsQL DF® foi aplicado. Na sequência, realizou-se o exame clínico bucal nas CA segundo diretrizes da OMS e do SB Brasil 2010. A maioria das CA era negra (88%), idade média de 10,4 (±2.9) anos, renda familiar de até dois salários mínimos, para 03 a 05 membros, diagnosticadas na triagem neonatal com anemia falciforme, internadas por crises álgicas, em uso de polifarmácia e com cárie dental (51%). O domínio “Sobre o Impacto da Minha Dor” foi preditivo da QLVDF (R² ajustado =56%; AIC=28.67; p=0,04). Nele, a cárie dental na dentição permanente piorou a QLVDF das CA (OR=0.53; IC95%=0.35-0.78; p<0,05), associando-se ao tipo de escola, posse de carro e do número de membros na família, de complicações da DF e de medicamentos. Os achados ratificam a dor como marca da DF e mostram a importância da saúde bucal na QLDF das CA. A implementação de políticas públicas específicas pode superar esse cenário.

ABSTRACT: This study evaluated forage-free diets supplemented with sodium bicarbonate (SB) based on ground flint corn on intake, apparent nutrient digestibility, ruminal parameters, and N balance. Four rumen-cannulatedDorper × Santa Inês lambs, with a body weight of 43.4 ± 0.85 kg (mean ± standard deviation) were used. The experimental design was a 4×4 Latin square. Each experimental period lasted 21 days. Experimental diets were: positive control, a diet without SB containing 400 g/kg DM of soybean hulls (CONT), and three diets based on ground flint corn, containing 10 (10SB), 20 (20SB) or 30 (30SB) g/kg DM of SB. Intake of neutral and acid detergent fiber was greater for CONT (P < 0.01) when compared to SB. Intake and apparent nutrient digestibility of dry and organic matter, ether extract, and crude protein did not differ. Intake (P = 0.01) and digestibility (P < 0.01) of non-fiber carbohydrates were greater for SB diets and neutral detergent fiber digestibility was greater (P = 0.03) for CONT. The total digestible nutrients and metabolizable energy were greater for SB (P = 0.04). Rumen concentrations of acetate (P < 0.01), isobutyrate (P < 0.01), butyrate (P < 0.01), isovalerate (P < 0.01), and total short-chain fatty acids (P < 0.01) were greater for CONT. Ruminal pH showed a quadratic (P = 0.05) response to SB levels, with greater values for 20SB. Sodium bicarbonate was efficient in increasing ruminal pH at the level of 20 g/kg DM without interfering with the intake and apparent nutrient digestibility characteristics.

RESUMO: O presente estudo avaliou a suplementação de bicarbonato de sódio (BS) em dietas sem forragem à base de milho moído sobre o consumo e a digestibilidade aparente dos nutrientes, os parâmetros ruminais e o balanço de N. Foram utilizados quatro cordeiros Dorper × Santa Inês, com um peso corporal inicial de 43,4 ± 0,85 kg (média ± desvio padrão). O delineamento experimental foi quadrado latino 4×4. Cada período experimental durou 21 dias. As dietas experimentais foram: controle positivo, sem BS, contendo 400 g/kg de MS de casca de soja (CONT) e três dietas à base de milho moído, sem casca de soja, contendo 10 (10BS), 20 (20BS) ou 30 (30BS) g/kg de MS de BS. O consumo de fibra em detergente neutro e ácido foi maior (P < 0,01)para o CONT quando comparado com BS. O consumo e a digestibilidade aparente da matéria seca, matéria orgânica, extrato etéreo e proteína bruta não diferiram entre os tratamentos. O consumo (P = 0,01) e digestibilidade (P < 0,01) dos carboidratos não fibrosos foram superiores para as dietas contendo BS e a digestibilidade da fibra em detergente neutro foi maior para o CONT. Os teores de nutrientes digestivos totais e energia metabolizável foram superiores para as dietas contendo BS (P = 0,04). A concentração ruminal de acetato (P < 0,01), isobutirato (P < 0,01), butirato (P < 0,01), isovalerato (P < 0,01) e ácidos graxos totais de cadeia curta (P < 0,01) foram mais elevadas para o CONT. O pHruminal apresentou resposta quadrática (P = 0,05) em relação aos níveis de BS, sendo observado maior pH para os animais alimentados com a dieta 20BS. O BS foi eficiente em aumentar o pHruminal no teor de 20 g/kg MS sem interferir no consumo e na digestibilidade aparente dos nutrientes. Portanto, 20 g/kg de MS é a dose indicada de BS em dietas sem forragem para terminação de cordeiros em confinamento.

Resumo O objetivo do estudo é analisar o índice de dentes cariados, perdidos e obturados (CPO-D) na idade de 12 anos da Região Centro-Oeste e identificar fatores associados, segundo a Pesquisa Nacional de Saúde Bucal, o SB Brasil 2010. É um estudo transversal de base populacional do banco de dados do SB Brasil 2010, realizado nas capitais de Mato Grosso, Mato Grosso do Sul, Goiás, Distrito Federal e uma amostra de municípios da região. Os dados foram analisados pelo teste de qui-quadrado e razões de prevalências com seus respectivos intervalos de confiança, a um nível de significância de 0,05. A regressão de Poisson foi empregada na análise múltipla para analisar a associação entre a variável desfecho e as variáveis explicativas. As variáveis independentes que se mostraram associadas ao CPO-D foram: o estado de moradia em Mato Grosso, Goiás e Mato Grosso do Sul; a renda per capita ≤ R$500,00; dificuldade para comer e dormir, e o motivo da consulta por Dor/Extração/Tratamento/Outros. A média do índice CPO-D foi de 2,14 e a prevalência da cárie dental foi de 41% dos adolescentes.

RESUMO Objetivos: Estimar a prevalência da síndrome de burnout (SB) e fatores associados entre médicos plantonistas de unidades de terapia intensiva (UTI) de São Luís-MA. Métodos: Participaram 60 médicos plantonistas de seis UTIs de São Luís-MA, investigados em setembro a dezembro de 2012, por meio de um questionário sociodemográfico abrangendo características condições de trabalho, fatores estressantes e do Maslach Burnout Inventory (MBI). Foram realizadas estatística descritiva e análise dos fatores associados à SB por meio do teste de Qui-quadrado e Razão de Prevalência. Resultados: Mulheres (n = 38), entre 30 e 39 anos, formadas há 10 anos ou menos, atuando há cinco anos ou menos em UTI, em dois hospitais, cuidando de seis a dez pacientes/plantão e com elevada carga horária, foram o público prevalente. Os principais fatores estressantes foram ruídos excessivos e possibilidade de complicação no atendimento. A prevalência do burnout com escore elevado (pontuações maiores ou iguais a 27 na exaustão emocional e 13 na despersonalização e menores que 31 na redução da realização profissional) foi de 13,3% em todas as dimensões e de 50% em pelo menos uma delas; níveis elevados de exaustão emocional estiveram presentes em 35% da amostra, seguidos pela baixa realização profissional (25%) e despersonalização (6,7%). Conclusões: A prevalência do burnout foi elevada, sendo mais frequente em mulheres, na UTI adulto, nos sujeitos que trabalhavam em dois ou mais hospitais e que assistiam mais de dez pacientes por plantão.

ABSTRACT Objectives: To estimate the prevalence of burnout syndrome (SB) and associated factors among attending physicians of intensive care units (ICUs) of São Luís-MA. Methods: Participants included 60 physicians on 6 MTIs from the metropolitan area of São Luís-MA investigated in September to December of 2012, using a self-administered questionnaire developed by the authors, covering sociodemographic characteristics, working conditions, stressors and the Maslach Burnout Inventory (MBI). Descriptive statistics and analysis of factors associated with SB through the Chi-square test and Prevalence Ratio. Results: Most are women (n = 38), between 30-39 years, formed 10 years ago or less, operating for five years or less In the ICU, in two hospitals, caring for six to ten patients/duty and high workload. The main stress factors were excessive noise and possibility of complications in attendance. The prevalence of burnout with a high score (scores greater than or equal to 27 in emotional exhaustion and 13 in depersonalization and less than 31 in reducing professional achievement) in one of the three dimensions was 50%, high scores in all three dimensions was 13.3%, and high levels in the dimensions analyzed separately in 35% of emotional exhaustion, depersonalization 6.7% in and 25% reduction in job satisfaction. Conclusions: The prevalence of burnout syndrome was high, being more common in women, in the adult ICU, work in more than two hospitals and attend more than ten patients per shift.

RESUMO Objetivo Analisar o comportamento sedentário (CS) como discriminador dos Transtornos Mentais Comuns (TMC) entre idosos. Métodos Estudo transversal com amostra composta por 310 indivíduos idosos, residentes no município de Ibicuí-BA. Foi utilizado um questionário contendo informações sobre características sociodemográficas, inatividade física no tempo livre e questões autorreferidas do tempo gasto sentado em um dia habitual da semana e de um dia do final de semana. Para estimar o ponto de corte do Comportamento Sedentário na discriminação dos TMC, utilizou-se a curva Receiver Operating Characteristic (ROC). Resultados A prevalência de TMC foi de 55,8%, sendo maior entre as mulheres (66,7%). Os maiores valores para a área sob as curvas ROC entre CS e TMC foi para o sexo masculino: CS/dia 0,58 (IC 95% = 0,49-0,67). Os pontos de corte propostos para CS/dia foram: homens: > 330 min/dia; mulheres: > 300 min/dia. Conclusão O comportamento sedentário é um indicador válido para identificação de suspeita de TMC em idosos, mostrando-se ser um fator de risco que deve ser observado pelos profissionais de saúde.

ABSTRACT Objective To analyze sedentary behavior (SB) as a discriminator of the Common Mental Disorders (CMD) among the elderly. Methods A cross-sectional study including 310 elderly individuals living in the municipality of Ibicuí-BA. Data were collected using a questionnaire addressing sociodemographic characteristics, physical inactivity during free time and self-reported questions about the time spent sitting during a typical weekday and weekend. A Receiver Operating Characteristic (ROC) curve was used to estimate the cut-off point of SB as a discrimination of CMD. Results The general prevalence of CMD was 55.8%, and was higher among women (66,7%). The highest values for the area under the ROC curves among SB and CMD was for males: SB/day 0,58 (95% IC = 0,49-0,67). The proposed cutoff points for SB/day were: men: > 330 min/day, women: > 300 min/day. Conclusion Sedentary behavior is a valid indicator for the identification of suspected CMD in the elderly, showing to be a risk factor that should be observed by health professionals.

A procedure was developed for the direct determination of SbIII and total inorganic Sb in water samples by hydride generation atomic absorption spectrometry (HG AAS), without pre-reduction of SbV. The NaBH4 concentration was maintained at 0.4% (m/v) to perform the selective generation of stibine from SbIII and online stibine generation was carried out with 5.0% (m/v) NaBH4 to obtain the total antimony concentration. SbV was calculated as the difference between the values obtained for total Sb and SbIII. In both cases, the procedure did not appear to be adversely affected by potential interferents such as SbV, AsIII, AsV, CaII, NaI, chloride and phosphate at a concentration of 0.5 mg L-1. For the proposed procedure, the detection limits were 0.2 µg L-1 for SbIII and 0.3 µg L-1 for total Sb, while the relative standard deviations were 0.1% for 10.0 µg L-1 SbIII and 0.4% for 10.0 µg L-1 total Sb. A sampling rate of approximately 30 determinations perhour was achieved, requiring 300 mL of NaBH4, and the amount of waste generated was in order of 960 mL, indicating that this analytical procedure can be considered as green. The method was shown to be satisfactory for the determination of trace levels of antimony in water samples. The result obtained for the assaying of certified drinking water samples was 9.7 ± 0.1 µg L-1 (certified value 10.0 ± 0.5 µg L-1).

To test the hypothesis that the physiognomy, structure and dynamics of woody species are influenced by the spatial gradient edge-interior, data were collected from these parameters in 2004, 2007 and 2010 in an Atlantic forest fragment. Species were sampled for the Canopy (DS), with circumference > 15 cm to 1.3 m soil and understory (SB) in circumference between ground level> 3 cm and CAP <15 cm on edge-gradient formed within 35 years. In 2004, we assessed three positions in the fragment: edge, intermediate and inner (> 150 m from the forest boundary), and analyzed 1,000 m² per site, divided into plots of 10 m², to measure individuals of higher class. In each plot a sub-plot of 5 m² for sampling understory was installed. Branches were collected from three adult individuals from the species to obtain the density of the wood. The number of individuals (NI), basal area (BA), mortality (TM), recruitment rate (TR), periodic annual diameter increment (IPA), loss rate (P) and gain rate (G) Area and basal turnover rates in number of individuals (TN) and basal area (TA) class tree component in the three locations showed no significant edge effect. At the edge, the understory had lower values of NI and AB and higher TM than in the forest interior. Differences between the strata occur regardless of edge sealing, since young plants present in most individuals in the sample class SB, which are more sensitive than adult trees to changes caused by the creation of the edge. Rates of loss and gain of AB and AB turnover in NI and in SB presented higher values than on the DS, which points to a stratum with larger changes. In DS there were no differences in species richness among environments differs from that observed in SB. The floristic composition of the DS in environments closer to the forest limit was quite distinct from that of the interior, indicating that there has been no recovery of floristic composition. All environments SB had low similarity. The edges of the DS and SB had a higher concentration of individuals in class intervals smaller density values timber. The DS has already recovered biomass, although the edge and intermediate environments have not recovered species composition late. The SB still suffers the edge effect. Possibly, the highest concentration of individuals is in class with lower density wood result on edge.

Avaliou-se o desempenho produtivo e características quantitativas e qualitativas de carcaça e dos não-componentes de carcaça de cordeiros SPRD (Sem Padrão Racial Definido) cruzados com as raças Santa Inês (SI) e Somalis Brasileira (SB) terminados em confinamento. Foram utilizados 16 cordeiros desmamados, machos, não castrados, com peso inicial 19,7±2,0kg e três meses de idade. Adotou-se o delineamento em blocos ao acaso, com blocos representados pelo peso inicial de cada grupo genético (½ SPRD x ½ SI e ½ SPRD x ½ SB), com oito animais por grupo. Os ovinos ½ SPRD x ½ SI apresentaram maior ganho de peso diário e total, comprimento e perímetro de pernil, comprimento interno da carcaça, peso e rendimento do corte serrote, peso e rendimento dos não-componentes da carcaça (pulmão e traqueia, fígado, rins, cabeça e patas). Os cordeiros ½ SPRD x ½ SB apresentaram maiores valores para escore de condição corporal inicial e final, espessura de gordura subcutânea, grau de acabamento, pH inicial e final. Assim, cordeiros mestiços ½ SPRD x ½ SI constituem uma alternativa promissora para o estabelecimento de sistemas produtivos mais eficientes, considerando a superioridade em ganho de peso e as características da carcaça relacionadas às medidas morfométricas, ao corte cárneo serrote e aos não-componentes da carcaça em relação aos animais ½ SPRD x ½ SB. No entanto, os cordeiros os cordeiros ½ SPRD x ½ SB apresentam superioridade quanto aos aspectos conservação da carcaça e nos casos de mercados com preferência por carcaça com maior teor de gordura.

We evaluated the growth performance and quantitative and qualitative characteristics of carcass and non-carcass components of crossbred lambs meat (½ undefined breed - SPRD x ½ Santa Inês - SI and ½ SPRD x ½ Somalis Brasileira - SB) finished in feedlot. We used 16 lambs weaned males, intact, with an initial weight of 19.7 ± 2.0 kg and about three months old. We adopted the design of randomized blocks, with blocks represented by the initial weight ranges for each genetic group evaluated (½ SPRD x ½ SI and ½ SPRD x ½ SB), with eight replicates in each group. Sheep ½ SPRD x ½ SI had higher average daily weight gain, total weight gain, length and head ham, carcass internal length, weight and yield of the hindquarter, weights and performance of non-carcass components (lung and trachea, liver, kidney, head and feet). ½ SPRD x ½ SB showed higher values for body condition scores initial and final fat thickness, degree of finish, initial pH and final. In this study, crossbred ½ SPRD x ½ SI lambs is a promising alternative to obtaining of production systems more efficient considering the superiority of weight gain and carcass characteristics related to morphometric measurements, cut meat diet hacksaw and non-carcass components in the ½ SPRD x ½ SB animals. However, SPRD ½ x ½ SB lambs feature superiority as the conservation aspects of carcass and in the case of markets with preference for carcass with higher fat content.

PURPOSE: The aim of this study is to identify the occurrence of Burnout Syndrome (BS) and assess its relationship with different labour-related aspects, among nursing professionals at two medium-sizes hospitals in the city of Cáceres. METHOD: This is a transversal and descriptive study, with a sample totalling 141 subjects. As an instrument of research, we used a questionnaire for the limitation of labour-related aspects, with the addition of the Maslach Burnout Inventory (MBI). RESULTS: Out of the 141 professional people considered, 13 had BS, according to the MBI. In relation to the different labour aspects, the professional people most affected were those with: work regime based on pay by the day, a working week of 30 hours, regularly hired, with double employment, lower graduation period, less time spent at the unit, and active in the administrative segment. CONCLUSIONS: Hence, there was the demonstration of the presence of BS within the sample, showing the need for the proposal of organisational changes within the working environment so as to reduce these factors and their interference on the health of the worker.

RESUMO A doença cérebro-vascular (DCV) está frequentemente presente na idade avançada, podendo se associar à patologia microscópica da substância branca (SB) e à disfunção cognitiva. A presente revisão investiga a relação entre DCV, status cognitivo e a integridade da SB, através da avaliação pelo tensor de difusão (DTI). Métodos: Os estudos em DTI foram selecionados a partir das bases ISI e Pubmed entre 2002 e 2012. Resultados: Os estudos evidenciaram alterações do DTI na SB associadas à doença vascular e fornecem evidencia importante para o DTI como um método valioso para a detecção precoce da DCV. Conclusão: Os parâmetros do DTI podem servir como importantes biomarcadores na monitoração da doença vascular quanto a sua progressão e resposta terapêutica e parecem representar um marcador substituto da integridade da SB.

ABSTRACT Cerebrovascular disease (CVD) is often present in old age and may be associated with microstructural pathology of white matter (WM) and cognitive dysfunction. The current review investigated the relationship between CVD, cognitive status and WM integrity as assessed by diffusion tensor imaging (DTI). Methods: DTI studies were searched on ISI and Pubmed databases from 2002 to 2012. Results: Studies evidenced DTI changes in WM as associated with vascular disease and provide increasing support for DTI as a valuable method for early detection of CVD. Conclusion: DTI parameters can serve as important biomarkers in monitoring vascular disease progression and treatment response and may represent a surrogate marker of WM tract integrit.

O objetivo desse trabalho é apresentar e discutir a determinação dos parâmetros de dispersão de ar em células mecânicas de flotação, em circuitos industriais brasileiros. Foram investigados os circuitos rougher e scavenger das usinas RPM, Taquari-Vassouras, Copebras e Fosfértil-Catalão (atual Vale Fertilizantes). Nas usinas RPM e Taquari-Vassouras, foram determinados a velocidade superficial do ar (Jg), o hold-up do ar (εg), o diâmetro médio de bolhas (d32) e o fluxo de área superficial de bolhas (Sb). Para as outras usinas, foram determinados somente o Jg e εg. Os resultados mostraram que, com exceção da RPM, todos os circuitos investigados apresentaram baixos valores para os parâmetros de dispersão do ar. Taquari-Vassouras apresentou os mais baixos valores médios para Jg e εg, respectivamente, 0,05 cm/s e 5%. Os maiores valores de Jg foram determinados no circuito rougher da Copebras, 1,17 cm/s, ao passo que a RPM apresentou os maiores valores para o hold-up e tamanho de bolha, respectivamente, 31% e 2,61mm.

The aim of this paper is to present and discuss the air dispersion parameters determined for industrial Brazilian flotation circuits. The rougher and scavenger circuits of RPM, Taquari-Vassouras, Copebras and Fosfertil-Catalão (today Vale Fertilizantes) were investigated. For RPM and Taquari-Vassouras, the superficial gas velocity (Jg), gas hold-up (εg), bubble size diameter (d32) and superficial area bubble flux (Sb) were measured, whereas only the Jg and εg were measured in the other circuits. The results pointed out that, except for RPM, all the circuits presented very low values for the air dispersion parameters. Taquari-Vassouras presented the lowest values for average Jg and gas hold-up: 0.05 cm/s and 5%, respectively. The highest Jg value was presented for the rougher circuit of Copebras, 1.17cm/s, while RPM presented the highest values for εg and bubble size, respectively 31% and 2.61mm. In the circuits where the calculation of the Sb parameter was possible, the results obtained lay in a range lower than those reported in literature.

Microbial insecticides for cockroach control, such as those containing entomopathogenic fungi, may be an alternative to reduce contamination by chemicals in housing and food storage environments. Virulence of isolate ESALQ1037 belonging to the Metarhizium anisopliae complex against nymphs and adults of Blattella germanica (L.), and its infectivity following exposure of insects to a contaminated surface or to M. anisopliae-bait were determined under laboratory conditions. Estimated LD50 15 d following topical inoculation was 2.69 x 10(5) conidia per adult, whereas for nymphs the maximum mortality was lower than 50%. Baits amended with M. anisopliae conidia had no repellent effect on targets; adult mortality was inferior to 25%, and nymphs were not susceptible. All conidia found in the digestive tract of M. anisopliae-bait fed cockroaches were unviable, and bait-treated insects that succumbed to fungal infection showed a typical mycelial growth on mouthparts and front legs, but not on the hind body parts. As opposed to baits, the use of a M. anisopliae powdery formulation for surface treatment was effective in attaining high mortality rates of B. germanica. Both nymphs and adults were infected when this delivery strategy was used, and mycelia growth occurred all over the body surface. Our results suggest that the development of powders or similar formulations of M. anisopliae to control B. germanica may provide faster and better results than some of the strategies based on baits currently available.
