ABSTRACT: Objective: Analyzing the occurrence of incidents related to health care in hospitalized children. Material and method: An exploratory, descriptive and quantitative research conducted from a database of reports of incidents and adverse events involving children conducted between 2016 and 2018 from a teaching hospital belonging to the Unified Health System (SUS), located in Salvador - Bahia. The data were analyzed in the STATA version 12 program. Results: During the study period, 126 incidents were reported. Most of the children who suffered incidents were between 0 and 3 years old (57.14%); were male (58.73%); and belonged to the black race (87.92%). The incidents occurred mostly in the morning shift (29.37%), and the notifications were identified in 71.46% of the cases and were performed by nurses (88.10%). The most reported incidents were falls (29.37%); surgical (23.02%); phlebitis (9.52%); and skin lesions (8.73%). There was damage to patients in 39.68% of the cases, which was mild (80%). Conclusions: The findings indicate the need to create methods for assessing risk factors that favor the occurrence of incidents such as falls and other situations that compromise the safety of hospitalized children, since these patients have peculiarities that need to be considered in health care.

Abstract The aim of this study was to identify tumor parenchyma cells exhibiting immunohistochemical profile of stem cells by evaluating the immunoreactivity of OCT4 and CD44 in a number of cases of salivary gland neoplasms. The sample consisted of 20 pleomorphic adenomas, 20 mucoepidermoid carcinomas, and 20 adenoid cystic carcinomas located in major and minor salivary glands. The expression of OCT4 and CD44 was evaluated by the percentage of positive cells and the intensity of expression. All studied cases showed positive expression of OCT4 and CD44 and higher values than the control groups. For OCT4, luminal and non-luminal cells were immunostained in the case of pleomorphic adenomas and adenoid cystic carcinomas. Moreover, the immunoreactivity of CD44 was particularly evident in the non-luminal cells of these lesions. In mucoepidermoid carcinomas, there was immunoreactivity for both markers in squamous and intermediate cells and absence of staining in mucous cells. For both markers, a significantly higher immunostaining was verified in neoplasms located in the major salivary glands compared with lesions in minor salivary glands (p<0.001). In the total sample and in minor salivary glands, malignant neoplasms exhibited higher immunoreactivity for OCT4 than pleomorphic adenoma. A significant moderate positive correlation (r = 0.444 and p ≤ 0.001) was found between OCT4 and CD44 immunoexpression in the total sample. The high expression of OCT4 and CD44 may indicate that these proteins play an important role in identifying tumor stem cells.

ABSTRACT Background: Along the vertical canopy profile, natural light availability is variable and may induce leaves morphophysiological changes due to phenotypic plasticity. Morphological changes in juvenile and adult leaflet of compound leaves of plant species is still poorly understood, including in woody species of gallery forests. The present study evaluated the leaflet morphophysiological characteristics and plasticity index of three woody species in canopy and understory leaves in a gallery forest. Results: All morphophysiological characteristics varied within species (Myracrodruon urundeuva Allemão, Copaifera langsdorffii Desf. and Tapirira guianensis Aubl.). The leaflets of canopy trees showed significantly higher values of petiole length (PL) and diameter (PD), leaflet thickness (fresh - FT and dry - DT), specific leaf mass (SLM), in relation to understory leaflets. On the other hand, relative water content (RWC) did not change between adult trees and saplings, except for T. guianensis. The plasticity index of leaflet characteristics varied significantly within species. Plasticity index of three morphophysiological characteristics (PL, PD and DT) varied between species. PL and PD had the highest plasticity index values across species, whereas RWC had the lowest plasticity.. Conclusion: Plasticity index of the tree species associates these leaflet morphophysiological traits (PL, PD and DT) with variations in the physical environment between strata of a gallery forest.

ABSTRACT OBJECTIVE To determine the prevalence of cigarette use among adolescents and to identify associated health risk behaviors. METHODS This is a cross-sectional study with a representative sample, composed of 1059 adolescents between 13 and 19 years old, enrolled in primary and secondary public schools of Olinda, Pernambuco, in 2014. Information was obtained through self-administered questionnaires (validated version of YRBS 2007). Cigarette experimentation was defined as smoking at least once in life. Adolescents who smoked at least one day within 30 days prior to the survey were considered current smokers. Most students were female and 16 years old or older. RESULTS Almost 30% used it in life and about 10% smoked within the 30 days before the survey. Suicidal ideation (PR = 1.51, 95%CI 1.25–1.82), alcohol use (PR = 1.41, 95%CI 1.03–1.92), marijuana (PR = 1.64, 95%CI 1.37–1.96), excessive alcohol consumption (PR = 1.57, 95%CI 1.15–2.16) and sexual experience (PR = 1.78, 95%CI 1.43–2.21) have increased the risk of using cigarettes. Feelings of sadness (PR = 1.70, 95%CI 1.22–2.36), alcohol use (PR=2.40, 95%CI 1.12–5.12), excessive alcohol consumption (PR = 2.5, 95% CI 1.24–5.38), marijuana (PR = 2.31, 95%CI.57–3.39) and cocaine (PR = 1.99, 95%CI.32–3.01) increased the risk of cigarette use within the 30 days before the survey. CONCLUSIONS Cigarette use among adolescents from Olinda was high, being considered higher than the national prevalence. Possible factors associated with cigarette use were drug use (alcohol, marijuana, and cocaine) and behaviors related to sexual experience, feelings of sadness and suicidal ideation.

Abstract: Introduction: Depression is a heterogenous disorder of diverse etiology, progression and therapeutic response. Increasing incidence of depression in young adulthood has been reported. The purpose of this paper was to evaluate the prevalence of depressive symptoms among medical students at a university which adopts an active learning method and to investigate possible associations to sociodemographic variables. Methods: Descriptive, cross-sectional study. An electronic questionnaire was applied to evaluate sociodemographic variables and depressive symptoms using the Beck Depression Inventory. Univariate and multivariate logistic regression analysis were performed. Results: A slight male predominance (n=93, 53.7%) was found among 173 students, along with an average median age of 24 [22-26]. Depressive symptoms were identified in 46.2% of the students (n=80): 33.5% (n=58) with mild symptoms, 9.2% (n=16) moderate, and 3.4% (n=6) severe. Female gender (p=0.032) and dissatisfaction with the active learning method (p<0.001) were independently associated with depressive symptoms in a multivariate logistic regression analysis with the chance of suffering from depressive symptoms increasing 2 and 3.5 fold, respectively. Living with one’s parents, additional psychiatric diagnosis, and lack of regular physical exercise were associated with depressive symptoms only in univariate analysis. Conclusion: The medical students presented a high prevalence rate of depressive symptons. Association between dissatisfaction with the active learning method and depressive symptoms may offer some insight regarding the pedagogical practices and deficiencies in the application of this method at the university in question. It is important to implement strategies that incorporate physical exercise into the pedagogical and curricular project to promote the mental and physical health of the students.

Resumo: Introdução: A depressão é um distúrbio heterogêneo, com etiologia, evolução e resposta terapêutica variadas, com relatos de aumento crescente na incidência entre os jovens. Dois objetivos nortearam este estudo: estimar a prevalência de sintomas depressivos entre acadêmicos de Medicina de uma universidade com métodos ativos de aprendizagem e investigar possíveis associações com variáveis sociodemográficas. Métodos: Trata-se de um estudo transversal descritivo. Aplicaram-se um questionário eletrônico com variáveis sociodemográficas e o Inventário de Depressão de Beck (BDI). Foram realizadas análise univariada e regressão logística multivariada. Resultados: Avaliamos 173 discentes, com discreta predominância de rapazes (n = 93, 53,7%) e idade mediana de 24 (22-26) anos. Verificaram-se sintomas depressivos em 46,2% (n = 80), dos quais 33,5% (n = 58) leves, 9,2% (n = 16) moderados e 3,4% (n = 6) graves. Sexo feminino (p = 0,032) e insatisfação com a Aprendizagem Baseada em Problemas - ABP (p < 0,001) se associaram de forma independente aos sintomas depressivos em regressão logística multivariada, com aumento na chance de sintomas depressivos de 2 e 3,5 vezes, respectivamente. Os fatores morar com os pais, ter outros diagnósticos psiquiátricos e praticar regularmente atividade física se associaram aos sintomas depressivos apenas em análise univariada. Conclusão: Os acadêmicos de Medicina apresentaram significativa prevalência de sintomas depressivos. A associação dos sintomas depressivos com insatisfação com o método ABP pode fomentar reflexões sobre a conduta pedagógica e as deficiências na aplicação da metodologia ABP na referida universidade. Ressaltamos a importância da implementação da atividade física no projeto pedagógico e curricular do curso de Medicina como estratégia para a promoção de saúde mental e física nos discentes.

Resumo O objetivo deste estudo foi analisar a relação entre padrão de sono e despesas de saúde em adultos, bem como identificar se atividade física, marcadores bioquímicos e obesidade afetam esse relacionamento. A amostra foi composta por 168 adultos com idade ≥ 50 anos atendidos por duas unidades básicas de saúde em Presidente Prudente, SP, Brasil. Foram avaliadas as despesas de saúde, padrões do sono, antropometria, atividade física, variáveis metabólicas e cardiovasculares. Foram utilizados Kruskal-Wallis, Mann-Whitney e Spearman. Os distúrbios do sono foram correlacionados positivamente com os custos mais elevados com medicamentos e negativamente com os custos com testes laboratoriais, mesmo após ajuste por fatores de confusão. Além disso, os custos de saúde também foram correlacionados ao escore de atividade física, pressão arterial, obesidade e variáveis metabólicas. Distúrbios graves do sono e alta porcentagem de gordura corporal foram associados ao aumento do uso de medicamentos. O padrão de sono está correlacionado com os custos de cuidados de saúde primários, obesidade e atividade física.

Abstract The aim of this study was to analyze the relationship between sleep pattern and healthcare expenditures in adults, as well as to identify whether physical activity, biochemical markers and obesity affect this relationship. The sample was composed of 168 adults aged ≥ 50 years attended by two Basic Healthcare Units in Presidente Prudente, SP, Brazil. Health expenditure, sleep pattern, anthropometry, adiposity index, physical activity, metabolic and cardiovascular variables were assessed. Statistical analyses were performed using Kruskal-Wallis, Mann-Whitney and Spearman tests. Sleep disorders were positively correlated to higher costs with medicines and negatively correlated to costs with laboratory tests, even after adjusts by confounders. In addition, healthcare costs were also correlated to physical activity score, blood pressure, obesity and metabolic variables. Severe sleep disorders and high percentage of body fat were associated with increased use of medications. Sleep pattern is correlated to primary care healthcare costs, obesity and physical activity level.

Resumo O artigo desdobra-se de pesquisa documental inscrita nos campos dos estudos de gênero e culturais e discute alguns dos modos pelos quais o gênero atravessa as proposições da Política Nacional de Atenção Integral da Saúde do Homem (PNAISH). Para isso, toma como referência um contexto discursivo em que termos como integralidade e equidade são reiteradamente apresentados e acionados, na direção de instituir propostas educativas e de cuidado voltadas à saúde e à educação de homens adultos. Argumentamos que, ao mesmo tempo em que essa amplitude coloca sob suspeita determinadas formas de viver a masculinidade, ela não desloca a centralidade dos processos curativos e parece contribuir para impregnar a política com uma visão utilitária, individualizando e culpabilizando os homens por seu distanciamento dos serviços de saúde.

Abstract This study stemmed from a documental research in the fields of Gender Studies and Cultural Studies, and discusses some of the ways that gender is regarded in the propositions of the PNAISH. To do so, it considers a discursive context in which words such as integrality and equality are repeatedly presented and used to launch educative and care proposals intended for adult men’s health and education. We argue that, at the same time that such amplitude puts certain ways of experiencing masculinity under suspicion, it does not deviates the focus on the healing processes and seems to contribute to impregnate the policy with a utilitarian view, thus individualizing men and blaming them for their detachment from health care services.

ABSTRACT The objective of this study was to evaluate the agronomic characteristics and yield of a sunflower crop grown together with forages in a crop-livestock integration system. The experiment was carried out in a randomized complete block design, in a 3×3 + 1 factorial scheme. Three sunflower intercropping with forage plants [sunflower + Urochloa ruziziensis (SB); sunflower + Panicum maximum cv. Tanzania (SP); sunflower + Urochloa ruziziensis + Cajanus cajan (SBGu)], sown in three ways [simultaneous sowing (SS), delayed sowing (DS), and simultaneous sowing with herbicide/graminicide (SSH) application], with the monocroped sunflower as a control, with three years of cultivation (2013, 2014, and 2015). The following characteristics were evaluated: plant height, stalk diameter, head diameter, number of achenes per heads, the mass of thousand achenes, harvest index, and the productivity of achenes. Data were submitted to analysis of variance, and the means were compared by the Tukey and Dunnett tests at 5% probability. The SB and SBGu intercropped promote greater sunflower productivity. The forage Panicum maximum cv. Tanzania in intercropped with sunflower reduces plant production components and productivity. Lapsed sowing delayed and simultaneous sowing with herbicide/graminicide application promote higher productivity of sunflower.

RESUMO Objetivou-se avaliar as características agronômicas e a produtividade do girassol cultivado em consórcio com forrageiras no sistema integração lavoura-pecuária. O delineamento utilizado foi blocos casualizados, em esquema fatorial 3 × 3 + 1. Assim, foram estudados, três consórcios do girassol com plantas forrageiras (girassol + Urochloa ruziziensis (GB), girassol + Panicum maximum cv. Tanzânia (GP), girassol + Urochloa ruziziensis + Cajanus cajan (GBGu)), semeados de três formas diferentes (semeadura simultânea (SS), semeadura defasada (SD) e semeadura simultânea com aplicação de herbicida/graminicida (SSH)), tendo o girassol solteiro como testemunha, com quatro repetições, em três anos de cultivo (2013, 2014 e 2015). Foram avaliadas as características: altura de planta, diâmetro da haste, diâmetro do capítulo, número de aquênios por capítulo, massa de mil aquênios, índice de colheita e a produtividade de aquênios. Os dados foram submetidos à análise de variância e as médias comparadas pelos testes Tukey e Dunnett, a 5% de probabilidade. Os consórcios GB e GBGu promovem maior produtividade do girassol. A forrageira Panicum maximum cv. Tanzânia em consórcio com o girassol reduz os componentes de produção da planta e a produtividade. A semeadura defasada e a simultânea com aplicação de herbicida/graminicida promovem maior produtividade do girassol.

Abstract This paper is the result of an ethnographic research that has been developed between/with Italian Brazilian in Santa Maria and in the towns of the Fourth Colony of Italian immigration (RS - Brazil). Our objective is to analyze the dynamics involved in the process of recognition of Italian citizenship, as well as the value attributed to the Italian passport. We observed that the passport, besides a document (object), crystallizes affective and symbolic values that make it more relevant than the waiting time for the citizenship and the economic cost that this process demands.

Resumo Este artigo é resultado de pesquisa etnográfica que temos desenvolvido entre/com ítalo-brasileiros em Santa Maria e cidades da Quarta Colônia de Imigração Italiana/RS, Brasil. Nosso objetivo é analisar as dinâmicas envolvidas no processo de reconhecimento legal da cidadania italiana, bem como o valor atribuído ao passaporte italiano. Observamos que o passaporte, para além de um documento (objeto), cristaliza valores afetivos e simbólicos que o tornam mais relevante que o tempo de espera pela cidadania e o custo econômico que esse processo demanda.

ABSTRACT: Secondary compounds have allelopathic action on germination and growth, and initial development of seedlings and beggar tick can have its germination and growth affected by the action of allelopathic extracts. Thus, this work aimed to evaluate the allelopathic potential of Brachiaria (Brachiaria brizantha), sunflower (Helianthus annuus) and sorghum extracts (Sorghum bicolor) on germination and initial growth of beggar ticks (Bidens pilosa). For this, an experiment was conducted in a completely randomized design with four treatments and six replicates and brachiaria, sunflower and sorghum extracts and control (distilled water) treatments. Extracts were obtained using 200 g of plant material and 1,000 mL of distilled water. Seeds were distributed in gerbox containing two sheets of germitest paper moistened with treatments and taken to germination chamber. Germination was daily monitored, and ten days after, initial growth was evaluated. Extracts did not reduce germination. However, they caused increase in germination time, mainly by brachiaria extract. Seedlings submitted to brachiaria and sorghum extracts showed lower growth. Brachiaria and sorghum extracts showed no action on germination, but controlled the initial growth of beggar tick, being potential natural herbicides.

RESUMO: Compostos secundários têm ação alelopática sobre a germinação, crescimento e desenvolvimento inicial de plântulas, e a Bidens pilosa pode ter sua germinação e crescimento afetados pela ação dos extratos alelopáticos. Nesse sentido, objetivou-se avaliar o potencial alelopático de extratos de braquiária (Brachiaria brizantha), girassol (Helianthus annus) e sorgo (Sorghum bicolor) na germinabilidade e no crescimento inicial de picão-preto (Bidens pilosa). Para isso foi instalado um experimento no delineamento inteiramente casualizado, com quatro tratamentos e seis repetições, sendo eles extrato de braquiária, girassol, sorgo e o controle (água destilada). Os extratos foram obtidos utilizando 200 g de material vegetal fresco para 1.000 mL de água destilada. As sementes foram distribuídas em caixa gerbox contendo duas folhas de papel germitest umedecidas com os tratamentos e levadas para a câmara de germinação. Foi acompanhada diariamente a germinação e, após 10 dias, foi avaliado o crescimento inicial. Os extratos não causaram prejuízos à germinação, porém, provocaram demora em seu tempo de eclosão, sendo o extrato de braquiária o mais prejudicial. As plântulas submetidas aos extratos de braquiária e sorgo apresentaram menor crescimento. Os extratos de braquiária e sorgo não apresentaram ação sobre a porcentagem de germinação das sementes de picão-preto, mas controlaram o crescimento inicial das plântulas e podem ser indicados para possíveis herbicidas naturais.

Abstract We describe the initial results of a neonatal screening program for four lysosomal storage diseases (MPS I, Pompe, Gaucher and Fabry) using the digital microfluidics methodology. The method successfully identified patients previously diagnosed with these diseases and was used to test dried blood spot samples obtained from 10,527 newborns aged 2 to 14 days. The digital microfluidic technology shows potential for a simple, rapid and high-throughput screening for these four diseases in a standard neonatal screening laboratory.

SUMMARY This work evaluated the effect of including sweet potato meal (SPM), as an alternative to corn in broiler chicken diets, on performance, carcass yield, intestinal morphometry, organ biometry, meat quality and drumstick pigmentation. The study used 936 male Cobb-500 chicks. The experiment had a completely randomized, 3x2 factorial design, with three diet types. These included corn as the energetic ingredient in the standard diet (corn-soybean meal, CSM), and an increasing (ISP) and decreasing (DSP) inclusion of sweet potato meal as a corn substitute, in association with exogenous enzymes, for a total of six treatments with six repetitions and 26 birds per plot. During the period of 1 to 21 days, there was an interaction (P<0.05) for the weight gain (WG) variable; the CSM diets promoted greater WG in relation to the ISP and DSP groups, when supplemented with exogenous enzymes. There was an increase (P<0.05) in surface absorption of the jejunum villi and relative weight of the pancreas, and worse feed conversion (FC), for the ISP and DSP diets. With exception of the pancreas, for the entire period of 1 to 39 days the performance, yield of the carcass and cuts, meat quality, relative weight of the liver, and feet pigmentation variables were not affected (P>0.05) by the factors evaluated. Sweet potato meal, independent of the inclusion program (ISP/DSP) and enzyme supplementation, could partially substitute corn in broiler chicken feed, guaranteeing good performance, carcass yield and meat quality.

RESUMO Avaliou-se o efeito da inclusão de farinha de batata doce (FBD), como alternativa ao milho em dietas de frangos de corte sobre o desempenho, rendimento da carcaça, morfometria intestinal, biometria de órgãos, qualidade de carne e pigmentação de canela. Foram utilizados 936 pintos de um dia, machos, da linhagem Cobb-500. Adotou-se um DIC em esquema fatorial 3x2, sendo três tipos de dietas, sendo o milho o ingrediente energético na dieta padrão (MFS), inclusão crescente (BDC) e decrescente (BDD) de farinha de batata doce como substituto parcial ao milho, associadas ou não ao uso de enzimas exógenas, totalizando seis tratamentos com seis repetições e 26 aves por parcela. No período de 1 a 21 dias, houve interação (P<0,05) para as variáveis de ganho de peso (GP) onde as dietas de MFS promoveram maior GP em relação aos grupos BDC e BDD quando suplementado com enzimas exógenas. Houve aumento (P<0,05) da superfície de absorção das vilosidades do jejuno, do peso relativo do pâncreas e piora na conversão alimentar (CA) promovido pelas dietas com BDC e BDD. No período integral de 1 a 39 dias (com exceção para o pâncreas) as variáveis desempenho, rendimento da carcaça e dos cortes, qualidade de carne, peso relativo do fígado e pigmentação das canelas não foram afetados (P>0,05) pelos fatores avaliados. A farinha de batata doce independente do programa de inclusão (BDC/BDD) e da suplementação de enzimas pode ser usada em rações de frangos de corte, garantindo bom desempenho, rendimento de carcaça e qualidade de carne.
