Abstract Objective: To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. Materials and Methods: This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. Results: The celiac trunk was "normal" (i.e., the hepatogastrosplenic trunk and superior mesenteric artery originating separately from the abdominal aorta) in 43 patients. In our sample, we identified four types of variations of the celiac trunk. Regarding the hepatic artery, a normal anatomical pattern (i.e., the proper hepatic artery being a continuation of the common hepatic artery and bifurcating into the right and left hepatic arteries) was seen in 82 patients. We observed six types of variations of the hepatic artery. Conclusion: We found rates of variations of the hepatic artery that are different from those reported in the literature. Our findings underscore the need for proper knowledge and awareness of these anatomical variations, which can facilitate their recognition and inform decisions regarding the planning of surgical procedures, in order to avoid iatrogenic intraoperative injuries, which could lead to complications.

O objetivo deste trabalho foi estimar a contribuição do efeito da idade, do período e da coorte de nascimento na mortalidade por câncer colorretal. Foram analisados dados de óbitos pela neoplasia entre indivíduos com mais de 35 anos de idade do Estado do Rio de Janeiro, Brasil, extraídos do Sistema de Informações sobre Mortalidade (SIM) entre 1980 e 2014. As taxas de mortalidade foram calculadas por gênero e faixa etária. O efeito da idade, período e coorte de nascimento foi estimado pelo método que utiliza funções estimáveis: desvios, curvaturas e drift, na biblioteca Epi do software R. As taxas de mortalidade por câncer colorretal padronizadas foram 27,37/100 mil homens e 21,83/100 mil mulheres em 2014. Verificou-se aumento da mortalidade pela neoplasia entre 1980 e 2014, sendo as taxas de mortalidade entre homens superiores às das mulheres após a década de 1990. O efeito idade foi observado com o aumento das taxas e o envelhecimento. A análise das gerações mostrou o menor risco de óbito nas coortes mais antigas comparadas às mais recentes coortes, o que pode estar ligado à adoção do estilo de vida ocidental. Tal cenário aponta a relevância da implantação de estratégias de rastreamento visando ao diagnóstico e ao tratamento precoce de lesões precursoras da doença.

Published: March 2018

RESUMO Avaliou-se o efeito da ordem dos testes na formação de classes de equivalência e no controle de estímulos após ensino de discriminação simples simultânea com um elemento redundante (mancha preta). Dezenove universitários realizaram treino de relações condicionais, além de testes de equivalência e de controle de estímulos com máscara. A ordem dos testes foi alterada em duas fases experimentais: (1) testes intercalados com treinos e (2) testes após os treinos. A mancha aparecia em um dos estímulos de treino. Desempenhos mais precisos ocorreram em testes conduzidos no final dos treinos. Escores altos foram relacionados com controle pelo S+ e pelo S- e os mais baixos com múltiplos controles, principalmente pela mancha. Sugere-se que a ordem dos testes interage com efeitos do elemento redundante.

Published: March 2018

RESUMO Trata-se de uma pesquisa qualitativa, cujo objetivo foi conhecer, a partir do olhar de mulheres chefes de família, o impacto da conjugalidade e do projeto parental não compartilhado no exercício da parentalidade. Participaram deste estudo dez mães que compunham uma família monoparental. Entrevistas semiestruturadas e grupos focais foram utilizados para a coleta de dados, tendo-se realizado uma análise de conteúdo temática. Os resultados evidenciaram que o projeto parental, quando não compartilhado pela dupla parental, produz fragilidades no exercício da parentalidade, em especial no que se refere ao envolvimento paterno. Ademais, identificou-se que, não obstante às mudanças atribuídas ao papel do pai na família, o exercício da paternidade ainda parece ser considerado, na perspectiva das mulheres, como opcional para muitos homens.

Published: March 2018

RESUMO O brincar primitivo do bebê poderia nos revelar traços precoces de uma provável organização autística em curso na criança pequena? Em que medida o investimento do bebê face aos objetos do mundo externo e do ambiente poderia ser associado a suas primeiras experiências com o objeto materno? Tais questões são levantadas neste artigo, cujo principal objetivo é abordar o processo de subjetivação da criança autista a partir da correlação entre o brincar primitivo do bebê e o brincar simbólico da criança. Por meio de um estudo longitudinal de bebês com risco de autismo, constatou-se que, desde uma idade precoce, é possível detectar particularidades na maneira como eles investem e interagem com os objetos do ambiente.

Published: March 2018

ABSTRACT Remote sensing allows for identification of regularities and irregularities in land use and land coverage (LULC) change in relation to environmental legislation. The aim of this study was to delimit scenarios in the permanent preservation areas (PPAs) according to the Brazilian forestry law, with or without consolidated uses in the basin of Capivari River and the State of Rio de Janeiro in the Atlantic Forest biome. Mapping and analysis were performed on LULC in areas of permanent preservation using the following data: RapidEye-REIS satellite scenes acquired in 2012 and Bhattacharyya distance classifier and hydrography of the basin and digital elevation model (1:25.000) using Spring and ArcGIS software. The legal scenarios adopted were as follows: I) Federal Law N°. 4,771/1965 and the National Council for the Environment (CONAMA) N°. 303/2002; II) Federal Law N°. 12,651/2012; and III) Federal Law N°. 12,651/2012 and N°. 12,727/2012. The classification presented an excellent overall accuracy of 91.15% and a Kappa Index of 0.86 in relation to the samples of the six multipurpose classes having the anthropic uses of agriculture, burned pasture, exposed soil and urbanization, which were present with conflicting uses for Scenarios I, II and III. The new forest legislation for the PPAs of Scenario III impacted the reduction of 68% compared to Scenario I, which corroborates with the concerns on the conservation of water and soil resources.

Published: March 2018

ABSTRACT Portable X-ray fluorescence spectrometer (pXRF) has been recently adopted by the Soil Science community for uses in both field and laboratory, obtaining the total content of several chemical elements in a few seconds. Sulfuric acid digestion is an expensive and time-consuming laboratory analysis that provides contents of Fe2O3, Al2O3, SiO2, TiO2 and P2O5, important for soil studies. Due to few pXRF studies in tropical soils, this work aimed to compare contents of Fe2O3, Al2O3, SiO2, TiO2 and P2O5 obtained by pXRF with sulfuric acid digestion results, and to evaluate the effects of varying forms of preparing soil samples and scanning with pXRF on the resulting values in Brazilian soils. Soils were scanned in five conditions in-field (in situ) and in laboratory, evaluating varying sample preparation methods, particle sizes and soil moisture. Four pXRF scanning operational modes were tested. Linear regressions were adjusted between results of pXRF and sulfuric acid digestion. Equations were validated with an independent set of samples. Statistical analyses compared the methods of preparing the samples. Adequate linear models reached R2 of 0.99 and 0.89 for Fe2O3 and TiO2, respectively. Validation promoted R2 greater than 0.97 and RMSE and ME close to zero for both oxides. Statistical differences of pXRF results were found among the methods of preparing samples. pXRF spectrometer has great potential to obtain Fe2O3 and TiO2 content rapidly and economically with high correspondence with laboratory results of sulfuric acid digestion analysis. Varying methods of preparing the samples promote differences in the results of pXRF.

Published: March 2018

ABSTRACT The estimation of the reference evapotranspiration is an important factor for hydrological studies, design and management of irrigation systems, among others. The Penman Monteith equation presents high precision and accuracy in the estimation of this variable. However, its use becomes limited due to the large number of required meteorological data. In this context, the Hargreaves-Samani equation could be used as alternative, although, for a better performance a local calibration is required. Thus, the aim was to compare the calibration process of the Hargreaves-Samani equation by linear regression, by adjustment of the coefficients (A and B) and exponent (C) of the equation and by combinations of the two previous alternatives. Daily data from 6 weather stations, located in the state of Minas Gerais, from the period 1997 to 2016 were used. The calibration of the Hargreaves-Samani equation was performed in five ways: calibration by linear regression, adjustment of parameter “A”, adjustment of parameters “A” and “C”, adjustment of parameters “A”, “B” and “C” and adjustment of parameters “A”, “B” and “C” followed by calibration by linear regression. The performances of the models were evaluated based on the statistical indicators mean absolute error, mean bias error, Willmott’s index of agreement, correlation coefficient and performance index. All the studied methodologies promoted better estimations of reference evapotranspiration. The simultaneous adjustment of the empirical parameters “A”, “B” and “C” was the best alternative for calibration of the Hargreaves-Samani equation.

Published: March 2018

ABSTRACT Knowledge of the wet bulb and the root system of the Conilon coffee plant is highly important for the correct management of irrigation. Therefore, the aim of this work was to characterize the wet bulb and Conilon coffee root distribution under drip irrigation. The experiment was conducted in the city of São Mateus, ES, Brazil with five replications of a completely randomized design of a 4 x 6 split-plot scheme, which represents four points located according to plant location and six depths. Two points were located in the plant line and two points between lines. For row spacing, we used a split-plot scheme 5 x 6 with five points in relation with plant location and six depths with five replications. The coffee roots were analysed by volume, superficial area, length and diameter. The wet bulb was measured with tubes located in six points near the plants with two points in the plant row (between two plants) and five points between rows. The measurements were conducted at four depth ranges with three replications. The wet bulb reached a depth of between 0.40 and 0.50 m, providing an excess of water in depth, evidencing the importance of this characterization for the irrigation management of drip-irrigated Conilon coffee. The depth of the radicular system for better irrigation management efficiency of drip-irrigated coffee is 0.30 m, exhibiting 67.4% of root volume and 68.0% of surface area.

Published: March 2018

ABSTRACT Coffee rust is a fungal disease that has affected every coffee-producing region in the world. Given that the effectivity of the protectant and systemic fungicides applied routinely to control the spread of the causative agent of the disease (Hemileia vastatrix) has gradually diminished, besides are harmful to mammals and ecosystems, the objective of this work was to search for a mixture of harmless natural compounds with the potential to be applied in the field. So, a yeast strain producing a battery of long-chain carboxylic acids (CA) with fungicide properties was isolated from soil of coffee crop and identified as Pichia membranifaciens by ITS sequencing. Culture conditions of the yeast were optimized and the CA in the solution were characterized by Gas Chromatography-Mass Spectrometry (GC-MS) as ethyl formate (55.5 g L-1), octadecenoic acid (3.5 g L-1), propionic acid (7.2 g L-1), 3-(octadecanoyl)-propionic acid (7.2 g L-1) and methyl acetate (8.4 g L-1). Randomized field studies were conducted in three different locations in Chiapas, México. Five treatments were tested including three concentrations of the CA solution (389, 584 and 778 ppm) and copper oxychloride (5 000 ppm) as conventional control. The initial coffee rust incidence averages varied between sites: Maravillas (3-9%), Santo Domingo (10-16%) and Búcaro (16-22%). The treatments of CA solution proved to be effective at slowing down the progress of the rust disease even for the sites where initial incidence was high. Likewise, the CA solution reduced the viability of H. vastatrix spores, as assessed by fluorescence microscopy.

Published: March 2018

ABSTRACT Neonicotinoids are a relatively new generation of insecticides that have been used for control of pests such as aphids, leafhoppers and whiteflies. This paper presents for the first time a determination of residues of four neonicotinoid insecticides (acetamiprid, thiamethoxam, thiacloprid and imidacloprid) in Chilean honey using QuEChERS extraction and UHPLC-MS/MS analysis. The limits of detection and quantification found for all analytes ranging from 0.34 to 1.43 μg kg-1 and from 0.30 to 4.76 μg kg-1, respectively. The extraction using QuEChERS method provided recoveries over 79% and the precision showed coefficient of variation lower than 20%. These data are in agreement with the international criteria that recommend general recovery limits of 70 - 120%. Of the 16 samples analyzed, in three honey samples neonicotinoids pesticides were detected. These three samples were collected from the same geographical area (Rengo). Fruit and grain production characterize the province of Rengo. The analysis of the botanical origin of these honeys showed the absence of pollen grains of crops and the majority presence of pollen grains of weeds such as Medicago sativa, Galega officinalis and Brassica rapa, which could be associated with crops. Although the residue levels found were low, the results also confirm the actual occurrence of a transfer of neonicotinoid insecticides from exposed honeybees into honey.

Abstract Introduction: studying the influence of surfing on the prevalence of injuries may contribute to prevention. Objective: to analyze the influence of time practicing sports and the occurrence of previous surgery on the profile and prevalence of injuries caused by surfing. Methods: Sixty-six Brazilian surfers (26.16 ± 0.73 years old) participated in this study. Anthropometric data, physical activity level, surfing practice time and the prevalence of injuries (type of injury, anatomical region affected, and mechanism of injury) were evaluated. To assess which of the studied variables exerted significant influence on the mean number of injuries, a Poisson log-linear model was adjusted through R software (p < 0.05). Results: most surfers were classified as eutrophic (73%), very active (60.6%), had an average practice time of 10.1 ± 1 years, and were not members of a surfing federation (74%). It was also observed that 90.9% of participants reported injuries caused by surfing and 44.9% affected the lower limbs. The majority of these injuries affected the integumentary system (46.6%). The main mechanism of injury was impact with the board or seabed (40.4%). Furthermore, it was found that surfing federation members presented an average of 58.4% more injuries than non-members (p = 0.007). Surfers who had undergone previous surgeries showed an average number of injuries that was 56.9% higher than other surfers (p = 0.012). In addition, it was found that for each extra year of surfing, the average number of injuries increased by 2.5% (p = 0.0118). Conclusion: the average number of injuries increased with increment in time practicing the sport, previous surgery and membership in a surfing federation.

Abstract Introduction: Population aging may give rise to a greater burden of diseases and disabilities, leading to the greater use of health services and the need for studies of the aged population. Health care teams and specialized residency programs constitute a strategy for the monitoring of older adults’ health status. Objective: To investigate the socioeconomic profile and health status of older adults in different age groups cared for by a multiprofessional family health team. Methods: This cross-sectional, quantitative study was conducted with 249 older adults registered in a Family Health Strategy (FHS) program in Uberaba, MG, Brazil. Socioeconomic and health status data were collected through home interviews using a structured questionnaire. Chi-square analysis was used for descriptive and bivariate analyses (p < 0.05). Results: Most older adults aged 60-70 years were functionally independent, married and had a mean monthly income of 1-3 times the Brazilian minimum wage. Older adults aged 70 - 79 years made use of 1 - 3 medications and had morbidities such as depression, cataract and glaucoma. There was a greater proportion of illiterates in the age group 80 years or over. Conclusion: Socioecnomic and health status were associated with age groups. Of note, there was a higher prevalence of medication use and morbidities among older adults aged 70 -79 years. The knowledge of these characteristics helps FHS team members to implement more accurate and customized strategies and interventions to deliver more effective and efficient care to older adults. Moreover, participation in a multiprofessional team provides an interdisciplinary learning and work experience for health professionals.

Published: March 2018

Abstract Introduction: Low back pain is a common condition among older adults and an important cause of disability. Objective: To evaluate the relationship between functional performance of older adults with low back pain and the following variables: sociodemographic and clinical factors, self-perceived health and back pain beliefs. Methods: A cross-sectional study that used data from the Back Complaints in the Elders international consortium. Information about sociodemographic factors (sex, age, marital status, formal education), clinical factors (intensity and frequency of pain, comorbidities), self-perceived health, back pain beliefs and functional performance (measured by the disability component of the Late Life Function and Disability Instrument - LLFDI) were collected through self-report. 191 older adults above 60 years with a new episode of back complaints who did not have any cognitive disorder, visual or hearing impairment, or motor disabilities participated in the study. A bivariate analysis was conducted between each independent variable and each outcome. Associations with p < 0.20 were selected for the multiple linear regression analysis, which was carried out for each LLFDI domain. Results: The multiple regression coefficients of determination were significant despite the modest magnitude. The variables related to functional performance were back beliefs, self-perceived health, formal education, pain frequency and marital status. Conclusion: These results may contribute to the expansion of health professionals’ work in the therapeutic approach of low back pain, broadening its focus beyond clinical aspects in order to value beliefs of older adults and their self-perceived health.

Published: March 2018

Abstract Introduction: The sphygmomanometer test is an alternative and inexpensive method for assessment of muscle strength. This instrument was considered valid and reliable to measure the isometric strength in different health conditions, however, in individuals with limb amputations the properties of this instrument for this purpose, have not been investigated. Objective: To investigate the concurrent criterion validity, test-retest and inter-rater reliabilities of the aneroid sphygmomanometer test (AST) without modification, for assessment of the strength of subjects with lower limb amputations. Methods: Twenty-two subjects (57.6 ± 15.2 years) with lower limb amputations were included in this study. Maximum isometric force was assessed with a handheld dynamometer (microFet2®) and the AST. To identify differences between trials, one-way ANOVA was applied. To assess the concurrent criterion validity, test-retest and inter-rater reliabilities of the AST, Pearson’s correlation coefficients of determination and intra-class correlation coefficient (ICC) were calculated. Results: For all muscle groups, no differences were observed between the trials (0.00001 ≤ F ≤ 0.10; 0.90 ≤ p ≤ 0.99). Significant, positive, and high to very high correlations were found between the HHD and the AST measures for the different numbers of trials for all assessed muscles (0.76 ≤ r ≤ 0.93; p ≤ 0.02). Test-retest (0.67 ≤ ICC ≤ 0.97) and inter-rater reliabilities (0.78 ≤ ICC ≤ 0.97) were adequate. The values obtained with the AST were good predictors of those obtained with HHD (0.58 ≤ r2 ≤ 0.85). Conclusion: For individuals with lower limb amputation, the AST showed adequate concurrent criterion validity, test-retest reliability and inter-rater reliability for the assessment of lower limbs muscle strength.

Published: March 2018

Abstract Introduction: In soccer, the players’ positions have been associated with specific functional overload, which may cause sports injuries. Objective: To investigate the occurrence and characterize sport injuries according to soccer player position. Methods: 232 male soccer players (129 professionals and 103 amateurs) from different sport teams in Mato Grosso do Sul, Brazil, were distributed in groups according to their soccer player position. Besides anthropometric characteristics, sports injuries were registered by using a referred morbidity survey. The occurrence of injuries was analyzed by means of the Goodman Test. Logistic regression models were used to investigate the relationship between different risk factors and the occurrence/-recurrence of sports injuries. Results: Forwards showed higher occurrence rates of sport injuries than other soccer position groups. Joint injuries in lower limbs constituted the most frequent registered cases. Muscle injuries in the back region were the most registered sports injuries among midfielders, while muscle damages in lower limbs were the primary injuries registered for other line positions. In the etiologic context, contact was the main cause of sports injuries in all groups. Most athletes (195) reported recurrence of sports injuries. Conclusion: The occurrence of sports injuries was higher among forwards. Traumatic joint and muscle injuries were the most prevalent registers in all line positions.

Abstract Introduction: Cerebral Palsy (CP) is a non-progressive disorder that may compromise functional abilities of the upper limbs due to motor and sensitive loss, that are still poorly evaluated and described by reliable tools. Objective: This study aimed to evaluate motor quality and skills of the upper extremity in children with CP in regions of Trairi and Seridó from Rio Grande do Norte state (Brazil). Methods: It is a cross-sectional exploratory study, with a qualitative approach, with 17 children with CP, aged between four and eight years. The following instruments were used for upper extremity evaluation: Manual Ability Classification System (MACS), Quality of Upper Extremity Skills Test (QUEST) and Gross Motor Function Classification System (GMFCS). Results: Mean and standard deviation (sd) of QUEST total score and the domains dissociated movement, grasp, weight bearing and extensive protection were, respectively, 41.06/37.08; 53.12/34.50; 15.51/62.98; 37.76/37.52; 42.48/47.26. MACS and GMFCS median scores were, respectively, 3 (three) and 5 (five); high positive correlation was observed between MACS and GMFCS (rs=0.83) and high negative correlation between GMFCS and total QUEST (rs=-0.83), as well as between MACS and QUEST (rs=-0.84); and MACS and all QUEST domains (rs=-0.73; rs=-0.82; rs=-0.76; rs=-0.79), p<0.001. Conclusion: Children with CP showed deficit in motor quality and skills of the upper limb, allowing to infer functional limitations regarding manipulation of objects and consequent dependence during life activities.
Mindfulness-Based Cognitive Therapy in Major depressive disorder - systematic review and metanalysis
Authors: Liberali Rafaela
Published: March 2018

Abstract Introduction: MBCT practices increases the ability of concentration and attention, as well is particularly effective for people with current and treatment-resistant depression. Objective: To analyze the effects of the application of MBCT in symptoms of MDD. Methods: systematic review and meta-analysis. To find suitable studies, we searched PubMed/MEDLINE's database using the keywords mindfulness and major depressive disorder. Studies in English published between 2003 and 2015 were selected. The studies were evaluated according to their methodological quality by PEDro scale (score greater than 3), studies that showed empirical evidence, had an experimental study design (randomized and non-randomized), and whose full text was available. For the meta-analysis, we used a random-effects model with standardized mean differences and 95% confidence intervals. Results: Fourteen es were included, of which three were non-randomized, with only one group with intervention of MBCT, and 11 were randomized studies, divided into two-group samples and three-group samples. The non-randomized studies showed a PEDro score of 5, while the two-group and three-group randomized studies showed PEDro scores of 5-10 and 6-9, respectively. In the meta-analysis, the four randomized studies selected revealed a moderate effect of MBCT on the outcome of depression symptoms, with a mean difference of -0.52 (95% CI: -1.050 to -0.002; p = 0.04). Conclusion: The MBCT presented as a promising alternative for the treatment of this disorder.

RESUMO Objetivo Analisar a percepção materna acerca do cuidado paterno e identificar como esse cuidado configura-se em ações práticas no cuidado à criança/adolescente com doença crônica no cotidiano familiar. Métodos Estudo exploratório-descritivo, qualitativo, realizado no ambulatório pediátrico de um hospital público da Paraíba, entre novembro/2013 e abril/2014, com 10 mães cujos filhos tinham mais de seis meses de diagnóstico. Entrevista semiestruturada subsidiou a coleta de dados, que foi submetida à análise temática. Resultados Os pais participavam de cuidados rotineiros da criança, gerenciamento do tratamento medicamentoso, lazer, apoio ao binômio e atividades domésticas. Assumiam diferentes papéis nos cuidados dependendo da disponibilidade de tempo e da abertura materna para sua participação. Entre os casais separados houve afastamento dos pais nos cuidados, refletindo na saúde do filho. Conclusão A participação do pai no cuidado ao filho com doença crônica é fundamental, porém, ainda faz-se necessário um maior envolvimento deste nos cuidados.

ABSTRACT Purpose To characterize the linguistic profile of adults and elderly with Down Syndrome (DS) using the Arizona Battery for Communication Disorders of Dementia (ABCD). Methods Thirty adult individuals with DS were evaluated through the MoCA cognitive battery, four functional scales (Pfeffer, Lawton-IADL, Katz-IADL and IQCODE) and the ABCD battery, which evaluates Mental State, Episodic Memory, Linguistic Expression, Linguistic Comprehension and Visuospatial Construction. The scores obtained by the individuals in the ABCD were correlated to those obtained on the Lawton-IADL scale. Results Individuals with DS had significantly lower performance than cognitively normal adults and elderly as described in Brazilian studies. Due to the lack of similar studies in our country, we compared our results to those of elderly with Alzheimer's Disease (AD), verifying that the performance of the DS population is similar to that of AD patients, although the former presented better scores on episodic immediate memory tests. There was a significant positive correlation between the scores obtained in the Lawton-IADL and those on the constructs Mental State, Episodic Memory, Linguistic Comprehension and Total ABCD. Conclusion The ABCD battery is a useful tool in the evaluation of adults and elderly with DS and the performance of individuals in this battery correlates with indices of functionality. This is a pioneer study in Brazil, and it points to the need for a better characterization of the linguistic abilities of individuals with DS, in order to allow the elaboration of strategies that stimulate their communicative abilities as to promote greater social insertion for this population.
“O projeto já chegou até nós pronto e não podemos mudar muita coisa!”: a metodologia participativa do PAC e a atuação das lideranças comunitárias no projeto de (re)urbanização de uma favela do Rio de Janeiro
Authors: Blasi Cunha Juliana
Published: March 2018

Resumo Ao apresentar uma breve contextualização sobre as políticas habitacionais no país, o artigo, inicialmente, situa historicamente o projeto de (re)urbanização de favelas do PAC. Mais especificamente, através da etnografia, o texto busca descrever a metodologia participativa proposta pelos agentes da “equipe social do PAC” e a forma como tal metodologia é posta em prática, ressaltando os desafios e limitações dessa metodologia. O trabalho busca ainda analisar como moradores e lideranças se utilizam dos “meios oficiais” que lhes foram disponibilizados pelo PAC, mas também alguns mecanismos acionados por eles em suas práticas para expor demandas e assegurar objetivos diante desse processo.
Paradoxos da formalização: a inclusão social dos catadores de recicláveis a partir do caso do encerramento do aterro de Jardim Gramacho (RJ)
Authors: Lima Maria Raquel Passos
Published: March 2018

Resumo O artigo discute a emergência dos catadores de materiais recicláveis no âmbito institucional e jurídico, a partir da organização política da categoria e da criação de um marco regulatório inédito para a gestão de resíduos sólidos no país, com a sanção da Política Nacional de Resíduos Sólidos. A partir do trabalho de campo realizado no bairro de Jardim Gramacho, na Baixada Fluminense, o artigo apresenta o caso do fechamento do aterro de resíduos da localidade, descrevendo a organização e as negociações dos catadores, com foco na atividade das lideranças e sua busca pela criação de alternativas de trabalho e renda para os catadores locais. A narrativa aborda o fazer político dos catadores diante do contexto de execução de políticas públicas voltadas para a inclusão social da categoria, apontando divergências, clivagens e embates relativos à heterogeneidade própria dos catadores e as dificuldades em torno do exercício da representação pelas lideranças no universo estudado. Com isso, busca-se evidenciar contradições e paradoxos que emergem da implementação de medidas vigentes nos novos marcos regulatórios de resíduos e os efeitos dissonantes entre a concepção das políticas governamentais e sua execução prática em contextos específicos.
As armas dos fracos: estratégias, táticas e repercussões identitárias na dinâmica do acesso à saúde na fronteira Brasil/Paraguai
Authors: Nascimento Valdir Aragão , Andrade Sônia Maria Oliveira de
Published: March 2018

Resumo O presente artigo objetiva expor e discutir algumas táticas e estratégias adotadas por paraguaios indocumentados para ter acesso à saúde por meio do SUS no Brasil. A pesquisa de campo realizou-se especificamente entre a cidade paraguaia de Pedro Juan Caballero e a cidade brasileira de Ponta Porã. Outro objetivo é discutir as relações socioculturais de caráter identitário que essas táticas e estratégias engendram e oportunizam na faixa de fronteira em questão. No tocante às táticas e estratégias, elencamos as concepções teóricas de Michel de Certeau a respeito dessas categorias. Fredrik Barth e seus conceitos atinentes aos grupos étnicos dão a tônica de nossa análise acerca das diversas, e por vezes divergentes, identidades étnicas oriundas das inter-relações estabelecidas na dinâmica que propicia a existência de táticas e estratégias – no tocante ao acesso à saúde – na fronteira do Brasil com o Paraguai.

Published: March 2018

Resumo Nessa análise, partimos de um estudo, realizado entre 2014 e 2015, de “núcleos de Fome Zero” na cidade de Porto Alegre para entender os efeitos naquele contexto de um programa de entrega de alimentos a pessoas em risco de insegurança alimentar. Na primeira parte deste artigo, traçamos um perfil dos beneficiados em dois desses núcleos para ressaltar a extrema heterogeneidade da população beneficiada. Num segundo momento, estendemos nosso olhar para a dimensão organizacional do programa ao explorar a maneira com que pessoas – tanto gestores quanto lideranças comunitárias – reagem à situação problemática do momento: a irregularidade na entrega de alimentos. No início dessa investigação, usamos técnicas clássicas da pesquisa etnográfica nas próprias comunidades. Porém, a irregularidade do programa nos levou a incorporar a análise de documentos administrativos, entrevistas com gestores nos setores municipais e estaduais relevantes, e a observação do espaço político coletivo onde os representantes de núcleos debatiam suas dúvidas quinzenalmente: o Fórum Fome Zero. Sugerimos que enquanto métodos quantitativos fornecem detalhes importantes do programa (quantidade e periodicidade de entregas de alimentos), a abordagem qualitativa que privilegia as dinâmicas microterritoriais e que dá visibilidade às lideranças populares demostra outras formas de produtividade do programa ligadas a experiências de mobilização popular e controle social.

ABSTRACT Objective: To evaluate risk factors associated with asthma symptoms in adolescents in the 13- to 14-year age bracket. Methods: This was a cross-sectional study involving adolescents enrolled in randomly selected public schools in the city of Belo Horizonte, Brazil, and conducted with the use of the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire and its supplementary module for risk factor assessment. The ISAAC questionnaire was completed by the students themselves, whereas the supplementary questionnaire was completed by their parents or legal guardians. Variables showing p ≤ 0.25 in the univariate analysis were included in the multivariate analysis. Stepwise regression with backward elimination was used for variable selection. Results: We evaluated 375 adolescents, 124 (33.1%) of whom had asthma symptoms. The final multivariate analysis model revealed that asthma symptoms were associated with birth weight < 2,500 g (p < 0.001), day care center or nursery attendance (p < 0.002), maternal history of asthma (p < 0.001), contact with animals during the first year of life (p < 0.027), current contact with animals outside the home (dogs, cats, or farm animals; p < 0.005), and more than 20 cigarettes per day smoked by parents or other household members (p < 0.02). Conclusions: Exposure to animals in and outside the home is associated with asthma symptoms, as is environmental tobacco smoke exposure. Families, health professionals, and administrators of health care facilities should take that into account in order to prevent asthma and reduce asthma morbidity.
Between-occasion repeatability of fractional exhaled nitric oxide measurements in children
Authors: Barański Kamil , Zejda Jan E.
Published: March 2018

ABSTRACT The aim of the study was to assess short-term repeatability of measurements of fractional exhaled nitric oxide (FENO) and its correlates in children in the 6- to 9-year age bracket participating in a respiratory epidemiological survey. FENO was measured in two sessions one week apart in 101 children. Participants were divided into three groups: asymptomatic (n = 76); symptomatic (n = 14); and asthma (n = 11). Absolute and relative differences between the measurements, as well as concordance correlation coefficients, were used in order to assess repeatability. The two FENO measurements were strongly correlated (0.98). Although intragroup comparisons of the two measurements were not significantly different (p = 0.2), intergroup comparisons were. FENO measurements are reproducible in children in epidemiological settings.

Pada penelitian ini telah diproduksi dan dikarakterisasi komposit bioplastik dari partikel selulosa serat rami (Cellulose Micro Fibers/CMF) untuk memperkuat komposit bioplastik bermatriks pati tapioka. CMF rami diproduksi menggunakan metode milling (CMFM) dan ultrasonikasi (CMFU) dengan ukuran masing-masing adalah 3,51 µm dan 0,388 µm. Pembuatan dan karakterisasi komposit bioplastik dilakukan dengan metode casting menggunakan gliserol sebagai plastisizer, dan penambahan filler CMF rami. Sifat fisik, kekuatan tarik, struktur dan termal komposit bioplastik dikarakterisasi menggunakan SEM, UTM, XRD, dan DSC. Hasil pengujian menunjukkan bahwa ukuran dan konsentrasi CMF secara signifikan mempengaruhi fisik bioplastik komposit. Dari hasil SEM menunjukkan bahwa filler CMF berinteraksi dengan matriks pati tapioka, dimana bioplastik dengan CMF rami berukuran kecil memperlihatkan struktur kompak dan permukaan yang lebih homogen. Nilai optimum kekuatan tarik terjadi pada penambahan 8% (w/w) CMF rami dari hasil ultrasonikasi dan milling masing-masing meningkat menjadi 3,31MPa dan 2,71MPa dari 1,64 MPa. Sebaliknya pada sifat termal sedikit berpengaruh dengan penambahan CMF rami. Analisis Difraksi Sinar-X menunjukkan kristalinitas komposit bioplastik meningkat dengan penambahan CMF rami dari 8,65 % menjadi 20,21 % untuk CMFM dan 15,12% untuk CMFU.
