Les réfractaires de la bohème
Authors: Glinoer Anthony
Published: October 2015

This article aims to unite several writers and journalists under the common term of “refractory ones,” following the title of Jules Vallès’s book, Les Réfractaires (1866). These figures share an atypical literary career: Théophile Dondey, one of the 1830s Jeunes-France under the pen name of Philothée O’Neddy, refused to publish during most of his adult life; Gustave Planche became the ultimate untouchable literary critic; Albert Glatigny, a Parnassian poet, lived the life of a vagrant comedian; during and after the Paris Commune, Eugène Vermersch devoted himself to a sort of revolutionary absolutism that estranged him from his political and literary peers. These men’s intellectual and social trajectories question the ways in which we envision the mythical figure of the writer during the second half of the nineteenth century: at a time when the literary field became institutionalized, the “refractory ones” chose a path paved with poverty, illegitimization, and marginality.

Published: October 2015

Prenatal exposure to glucocorticoids (GCs) programs for hypertension later in life. The aim of the current study was to examine the impact of prenatal GC exposure on the postnatal regulation of the gene encoding for phenylethanolamineN-methyltransferase (PNMT), the enzyme involved in the biosynthesis of the catecholamine, epinephrine. PNMT has been linked to hypertension and is elevated in animal models of hypertension. Male offspring of Wistar-Kyoto dams treated with dexamethasone (DEX) developed elevated systolic, diastolic and mean arterial blood pressure compared to saline-treated controls. Plasma epinephrine levels were also elevated in adult rats exposed to DEXin utero. RT-PCR analysis revealed adrenal PNMT mRNA was higher in DEX exposed adult rats. This was associated with increased mRNA levels of transcriptional regulators of the PNMT gene: Egr-1, AP-2, and GR. Western blot analyses showed increased expression of PNMT protein, along with increased Egr-1 and GR in adult rats exposed to DEXin utero. Furthermore, gel mobility shift assays showed increased binding of Egr-1 and GR to DNA. These results suggest that increased PNMT gene expression via altered transcriptional activity is a possible mechanism by which prenatal exposure to elevated levels of GCs may program for hypertension later in life.

Offspring telomere length (TL) has been correlated with paternal TL, but the mechanism for this parent of origin-specific inheritance remains unclear. The objective of this study has been to determine the role of spermatozoa TL in embryonic telomere lengthening by using two mouse models showing dimorphism in their spermatozoa TL: Mus musculus vs Mus spretus and old vs young Mus musculus. Mus spretus spermatozoa displayed a shorter TL than Mus musculus. Hybrid offspring exhibited lower TL compared with Mus musculus starting at the two-cell stage, before the onset of telomerase expression. To analyze the role of spermatozoa telomeres in early telomere lengthening, we compared the TL in oocytes, zygotes, two-cell embryos and blastocysts produced by parthenogenesis or by fertilization with Mus musculus or Mus spretus spermatozoa. TL was significantly higher in spermatozoa compared with oocytes, and it increased significantly from the oocyte to the zygote stage in those embryos fertilized with Mus musculus spermatozoa, but not in those fertilized with Mus spretus spermatozoa or produced by parthenogenesis. A further increase was noted from the zygote to the two-cell stage in fertilized Mus musculus embryos, whereas hybrid embryos maintained the oocyte TL. Spermatozoa TL shortened with age in Mus musculus and the offspring from young males showed a significantly higher TL compared with that fathered by old males. These significant differences were already noticeable at the two-cell stage. These results suggest that spermatozoa telomeres act as a guide for telomerase-independent telomere lengthening resulting in differences in TL that persist after birth.

Introduction: Attention-deficit hyperactivity disorder is a risk factor of smoking and alcohol drinking in adolescence. Since attention-deficit hyperactivity disorder and smoking and alcohol drinking in adolescence are predictors for the development of substance use disorders in adulthood, it is important to understand the nature of these associations. Aim: The aim of the authors was to investigate associations between attention-deficit hyperactivity disorder symptoms and the joint use of alcohol and nicotine among 9th graders. Method: A representative sample of 944 pupils attending state-run secondary schools in Budapest were recruited. Generalized Linear Mixed Model and logistic regression analyses have been conducted. Results: The prevalence was 29.6% and 41.4% for current smoking and current alcohol drinking, respectively. The prevalence of their concurrent-use was 21.7%. Alcohol drinking and smoking showed a significant positive association with the total scores of Attention-Deficit Hyperactivity Disorder Scale and with the Attention Deficit and Hyperactivity/Impulsivity subscales. Conclusions: The findings highlight the potential importance of attention-deficit hyperactivity disorder in the development of the joint use of these substances. Orv.

A laktózintoleranciáról: Múlt és jelen – II. rész
Authors: Buzás György Miklós
Published: October 2015

The author summarises the interrelations between lactose intolerance, calcium and vitamin D metabolism and osteoporosis. Lactose intolerance enhances the risk of forearm and hip fractures in some patients. Lactase gene genotype and fracture risk are related in some populations. Calcium and vitamin D supplementation increase bone mineral content and they are justified in children, during pregnancy and lactation, and in postmenopausal women. The intake of milk and milk products could increase the risk of ovarian carcinoma. CC genotype of the lactase gene increased the risk of colorectal carcinoma in Finns; no such effect was observed in British, Spanish and Italian patients. Even small quantities of lactose in drugs (10–750 mg) could elicit intolerance symptoms due to individual susceptibility. In spite of public knowledge and advertising, controlled studies did not prove the beneficial effect of either a lactose-free diet, enzyme supplementation or probiotics in an evidence-based manner. While accepted guidelines are lacking, a personalised therapy is mandatory. In spite of increasing public interest in lactose intolerance, many unknown factors must still be studied. Orv. Hetil., 2015, 156(43), 1741–1749.

Published: October 2015

This study was conducted in Araucaria Forest remnants in the municipality of Colombo, eastern Paraná state, Brazil. Data on species occurrence, life forms and dispersal syndromes were collected once a week along a 9 km transect, revealing the presence of 512 species among trees (n = 135), shrubs (n = 121), herbs (n = 157), climbers (n = 70), epiphytes (n = 24) and hemiparasites (n = 5). Of 469 species classified according to dispersal syndromes, 42.4% were zoochoric, 33.6% autochoric and 23.8% anemochoric. The high richness observed, the highest among similar studies previously conducted in the Araucaria Forest, along with the occurrence of endangered species of trees (and mammals), indicates that the study area is an important remnant for biodiversity conservation.
Chaplaincy as Public Theology
Authors: Pattison Stephen
Published: October 2015

This article explores the need for a renewed and creative engagement with theology on the part of chaplains so as to articulate and assist the public work of chaplains in (mostly secular) institutions. Acknowledging the current performed public theology of chaplains and the dearth of formal theological activity, some of the possible inhibitors to engaging with theology are then discussed. Images and metaphors of theology are advanced with a view to showing the pluriform nature of this activity. It is then suggested that chaplains could adopt more creative and imaginative approaches to their theological traditions that might enable prophetic and apologetic roles within organizations, to the benefit of those organizations and of chaplaincy itself.
Assessing the Value of Chapel Services at a Mental Health Hospital
Authors: Tiano Noel , Maclean Kath
Published: October 2015

This pilot study aims to explore perspectives of service users regarding the chapel services at a regional provider for forensic, mental health rehabilitation and intellectual disability services in New Zealand. Adult clients and staff were invited to fill out a brief questionnaire which focused on five key participants’ satisfaction with chapel services. Interviews were conducted to investigate what spiritual practices they found helpful. The results showed a high rate of overall satisfaction amongst the 33 respondents. Ninety four percent felt welcomed, 85% felt hopeful, 97% felt safe, 82% connected with God or higher power and 88% connected with others. Helpful spiritual practices included rituals, social support, meaningful activities and insights gained into their growth. Further studies on faith, gender and culture amongst the various mental health services including clients in locked units were recommended. As well, spiritual care services could be more integrated with other healthcare disciplines.

Published: October 2015

ABSTRACTAs important as the establishment of projects of ecological restoration is its assessment post-implementation to know whether the area is becoming self-sustainable or need to be redirected. In this way, this study aimed to know the current situation of a 5-year-old rehabilitated riparian forest,inserted in an anthropogenic impacted region,at the das Velhas River, Minas Gerais State, studying the canopy openness and recruitment of seedlings as plant indicators. 15 plots were allocated in the forest, where hemispherical photographs were taken to analyze the canopy openness and evaluate all seedlings from 0.30 m to 1.30 m height.Canopy openness ranged from 23.7% to 38.8% between seasons and only 192 seedlings were found,from 13 species, five of them exotic and aggressive. Although canopy openness was low, it seems that lateral penetration of light has been favoring the development and dominancy of plants from invasive species, whereas few native ones have been recruited. The exotic/invasive plants may compromise the success of restoration mainly by competition with native planted species. The outcomes evidenced an unsustainability of the riparian forest and the requirement of some management actions to control exotic and invasive plants and ensure the preservation of the area and its ecological roles over time.

Published: October 2015

RESUMOEste trabalho foi desenvolvido com o objetivo de determinar os melhores parâmetros da pulverização utilizando pulverizador pneumático adaptado para a aplicação em florestas de eucalipto, através do estudo de gotas usando etiquetas hidrossensíveis. Essas etiquetas foram posicionadas nos dosséis dos eucaliptos em três alturas diferenciadas e três posições, com o auxílio do Feller-Buncher. A pulverização foi feita utilizando um pulverizador pneumático, em que se empregou uma vazão de ar de 11.300 m3 h-1 e TDP de 56,5 rad s-1 (540 rpm). Foram utilizados três índices volumétricos. Os parâmetros observados foram densidade de gotas, porcentagem de cobertura, diâmetro da mediana volumétrica (DMV), coeficiente de homogeneidade e amplitude relativa. Nas condições em que o experimento foi conduzido, o pulverizador pneumático utilizado atendeu às expectativas tanto em densidade de gotas quanto em porcentagem de cobertura, para a aplicação de inseticida em floresta de eucalipto. Os valores médios do coeficiente de homogeneidade e amplitude relativa foram condizentes com o tipo de pulverizador empregado. Assim, o pulverizador utilizado foi eficiente na aplicação de agrotóxicos em árvores adultas de eucalipto.

Published: October 2015

RESUMOEm ambientes naturais, a salinidade representa grande empecilho ao desenvolvimento dos vegetais. Visando à melhor compreensão dos efeitos que ela provoca na fisiologia de espécies arbóreas nativas, este trabalho objetivou avaliar o comportamento fisiológico de mudas de jatobá (Hymenaea courbaril L.) submetidas à salinidade em meio hidropônico. Portanto, um experimento foi realizado em casa de vegetação do Laboratório de Fisiologia Vegetal da Universidade Federal Rural de Pernambuco, adotando-se um delineamento experimental inteiramente casualizado em arranjo fatorial 3 x 2, composto por três tratamentos salinos: Controle (solução nutritiva sem adição de NaCl), Estresse moderado (adição de 50 mM de NaCl) e Estresse severo (adição de 100 mM de NaCl) e duas épocas de avaliação (1ª época: constatação do fechamento estomático; e 2ª época: após a verificação da abertura estomática das plantas submetidas à salinidade), com 20 repetições em cada tratamento. Durante o estudo, foram verificadas as trocas gasosas, as relações hídricas, os teores de pigmentos fotossintéticos e o acúmulo de solutos orgânicos e inorgânicos. Ao final do experimento, observou-se que as mudas de jatobá se ajustaram osmoticamente após a indução do estresse severo, uma vez que acumularam solutos orgânicos que promoveram a elevação da turgescência foliar, resultando na estabilização das trocas gasosas, mesmo após a submissão ao estresse severo.

ABSTRACTSchizolobium parahyba pv. amazonicum (Huber ex Ducke) Barneby (paricá) occurs naturally in the Amazon and is significant commercial importance due to its rapid growth and excellent performance on cropping systems. The aim of this paper was to evaluate a microbial inoculants such as arbuscular mycorrhiza fungi (AMF) and Rhizobium sp. that promote plant growth. The inocula was 10 g of root colonized and spores of Glomus clarum and/or 1 mL of cell suspension (107 CFU/mL) of Rhizobium sp. and/or 100 g of chemical fertilizer NPK 20-05-20 per planting hole. The experimental design was complete randomized blocks with five replications and eight treatments (n = 800). Plant height, stem diameter and plant survival were measured. The results were tested for normality and homogeneity of variances and analyzed by ANOVA and Tukey test (p < 0.05). Rhizobium sp and AM fungi showed no effect on plant growth. Environmental factors probably influenced the effectiveness of symbiosis of both microorganisms and plant growth. The chemical fertilizer increased S. parahyba growth. During the first 120 days plants suffered with drought and frost, and at 180 days plants inoculated with microorganism plus chemical fertilizer showed higher survival when compared with control. The results showed that the microbial inoculants used showed an important role on plant survival after high stress conditions, but not in plant growth. Also was concluded that the planting time should be between November to December to avoid the presence of young plants during winter time that is dry and cold.

RESUMOO fogo é comum no Cerrado e, geralmente, ocorre durante a seca, quando várias espécies frutificam ou dispersam as sementes. Entretanto, pouco se sabe sobre os efeitos do fogo na germinação das espécies do Cerrado. Este trabalho investigou o efeito da exposição a altas temperaturas na germinação de sementes de Dalbergia miscolobium Benth. e Plathymenia reticulata Benth., comuns no Cerrado e com uso potencial para recuperação de áreas degradadas e na recomposição de áreas de preservação permanente. As sementes foram coletadas em agosto de 2011, pesadas, separadas em três classes de tamanho e expostas a três temperaturas: 80 ºC, 100 ºC e 150 ºC por 2 e 5 minutos. Após os tratamentos, as sementes foram colocadas para germinar. A exposição a altas temperaturas afetou, de forma diferenciada, a germinação das espécies. Independentemente da classe de tamanho, a exposição das sementes até 100 °C, por 2 e 5 minutos, não alterou a germinação de D. miscolobium (91%). Entretanto, apenas as sementes maiores germinaram após a exposição a 150 °C, porém com redução significativa na germinação (53%; p<0,01). Para P. reticulata, a exposição a 80 °C por 2 e 5 minutos e a 100 °C por 2 minutos não alterou a germinação (71%), e nenhuma semente germinou após a exposição a 150 °C. A baixa resistência das sementes às altas temperaturas pode afetar significativamente o recrutamento de novos indivíduos após a ocorrência de queimadas no Cerrado.

RESUMOA quantidade de produção por pessoa por turno de trabalho pode ser questionada pelo empregado, pelo empregador e pelos sindicatos, instituições governamentais e certificadoras. No setor florestal, o processo de determinar metas de produção, em geral, não leva em conta os fatores ergonômicos. O objetivo deste trabalho foi determinar metas de produção para atividade de corte florestal com motosserra (abate e traçamento de árvores), levando em consideração os fatores ergonômicos relacionados à atividade, como forma de prevenir danos à saúde dos trabalhadores. Os fatores ergonômicos foram avaliados utilizando a metodologia de análise ergonômica validada no meio científico. A organização do trabalho foi avaliada segundo a metodologia de análise de sistemas e estudos de tempos. Os resultados indicaram que o nível de vibração total (eixos X, Y e Z), o ambiente térmico expresso pelo Índice de Bulbo Úmido-Termômetro de Globo (IBUTG), o nível de ruído e a carga cardiovascular foram superiores aos limites recomendados para jornada de 8 h de trabalho. Os movimentos realizados pelos trabalhadores não foram enquadrados como repetitivos. As forças de compressão no disco L5-S1 da coluna vertebral foram próximas ou superiores ao limite. Com exceção do fator repetitividade, todos os fatores exigiram pausas de recuperação, sendo o nível de vibração da máquina o fator com maior exigência de tempo de pausas. A necessidade de aumentar o tempo de pausa ergonômica e diminuir o tempo de trabalho efetivo fez que a meta de produção fosse reduzida em 18%, para evitar danos à saúde do trabalhador.

RESUMOUm importante aspecto a ser considerado na produção de carvão vegetal é o longo período de resfriamento dos fornos de alvenaria, acarretando na baixa produtividade e exigindo maior número de fornos para suprir a demanda de produção. Pesquisas têm sido desenvolvidas para a redução do tempo de resfriamento dos fornos retangulares, utilizando trocadores de calor. Dessa forma, o objetivo deste trabalho foi avaliar três modelos de trocadores de calor que promovam a redução significativa do tempo de resfriamento. A pesquisa foi realizada na unidade produtora de carvão vegetal Buritis, da Empresa Arcelor Mittal Bioflorestas, localizada na cidade de Martinho Campos, MG. Foram avaliados três diferentes trocadores de calor (Modelos 1, 2 e 3), determinando o tempo, em dias, que os fornos retangulares levavam para atingir a temperatura de 50 ºC em relação ao resfriamento natural. O Modelo 1 apresentou ganho real no tempo de resfriamento de 12,5%; o Modelo 2, ganho real de 38%; e o Modelo 3, com fluxo de gás convencional, apresentou ganho médio de 32%, enquanto no fluxo de gás invertido o ganho foi de 43%. Conclui-se que os trocadores de calor avaliados foram eficientes na redução do tempo de resfriamento dos fornos retangulares para produção de carvão vegetal, elevando, assim, a produtividade dos fornos. O trocador de calor Modelo 3, com fluxo de gás invertido, apresentou o maior ganho real no tempo de resfriamento, além do menor número de focos de incêndio durante o descarregamento do carvão vegetal.
Estimando o desalinhamento cambial brasileiro: uma análise de robustez a partir do modelo global com mecanismo de correção de erros
Authors: Marçal Emerson Fernandes
Published: October 2015

ResumoO presente trabalho tem por objetivo comparar duas metodologias para cálculo de desalinhamento cambial. A primeira metodologia consiste na estimação do desalinhamento cambial a partir de técnicas multivariadas de séries de tempo nas quais apenas variáveis associadas ao país em análise são utilizadas na modelagem. A segunda metodologia consiste na utilização de fatores globais, como sugerido pelo Modelo Vetorial Autorregressivo com Correção de Erros Global (VAR-MCEG). O caso brasileiro é analisado a partir das duas metodologias. Os resultados sugerem que as estimativas podem diferir em magnitude para diferentes períodos. Ambas as metodologias sugerem que o canal pelo qual termos de troca afetam a taxa de câmbio real brasileiro é indireto. Melhorias de termos de troca levam a uma melhora da posição internacional de investimento e, logo, geram uma valorização da moeda brasileira. Os resultados da metodologia GVECM sugerem que a taxa de câmbio real brasileira é afetada no longo prazo pelo nível de taxa de câmbio real dos seus parceiros comerciais.

ResumoEste artigo estima a probabilidade de informação privilegiada (PIN) para ações do Índice Brasil durante o período de 2006 até 2011. O PIN é uma proxypara informação privada e é incorporado ao método de Fama French (1993) para separar os portfolios e explicar seus retornos. A combinação do PIN com as variáveis valor de mercado e índice book-to-market possibilita, para alguns portfolios, aumento do retorno e diminuição do risco. A significância das variáveis na explicação dos retornos é testada utilizando modelos de Markov-switching. Os resultados demonstram que o PIN é um fator importante na explicação dos retornos dos portfolios.

Nitrogen (N) is the most limiting nutrient for corn production. Thereby, the goal of the paper was to evaluate inoculation methods of Azospirillum brasilense in order to partially supply N required by the crop. The experiment was carried out in Guarapuava, PR, Brasil, in 2011/2012 growing season. Randomized blocks with factorial 3 inoculation methods (seed treatment, planting furrow and non-inoculated control) x 5 doses of nitrogen (0, 75, 150, 225 and 300kg ha-1) x 8 replications was used as the experimental design. Leaf are index, foliar nitrogen content, total chlorophyll, grains per ear and yield were evaluated. There was significant interaction between inoculation methods and nitrogen fertilization to leaf area index, but not for yield. Inoculation with the diazotrophic bacteria provided yield increase of 702kg ha-1 for inoculation in seeding furrow and 432kg ha-1 for inoculation in seed treatment compared to the control, but both treatments did not differ between each other. Furthermore, total chlorophyll, grains per ear and yield were positively affected, with quadratic response, by the nitrogen fertilization in broadcasting
A grazing height target to minimize tiller stem elongation rate in annual ryegrass swards

Published: October 2015

ABSTRACT: Italian ryegrass (Lolium multiflorum Lam) is one of the most cultivated temperate annual forage crop around the world. Despite that, there is little information about the process of stem elongation during its vegetative growth. This information would be useful for grazing management purposes. Thus, the aim of this study was to assess the herbage accumulation and stem elongation rates in annual ryegrass pastures submitted to intermittent stocking. The experimental design used was a completely randomized 2x2 factorial with three replications. The treatments were defined by the combination of two pre-grazing heights (15 and 25cm) associated with two post-grazing heights (4 and 8cm). The herbage accumulation rates were higher in pastures with 25cm pre-grazing associated with post-grazing heights of 8cm. However, leaf production rate was only affected by post-grazing height, with higher values being recorded for stubbles heights of 8cm, regardless of pre-grazing height. Stem elongation rates in annual ryegrass tillers increased rapidly when pastures reached around 18cm, a condition where there was a relatively low competition for light, suggesting that; 1) pre-grazing heights of 18 to 20cm in annual ryegrass could be used as a upper limit for grazing management purposes whether the objective is to minimize stem contribution in accumulated herbage and 2) It seems that stem elongation is as inevitable process (independently of competition for light) and that this could be related to the necessary strength of stems, pseudostems and sheaths to support larger and heavier leaves.

The study aimed to evaluate biocompatibility, osteoconduction and osseointegration of a pasty composite of hydroxyapatite (20%) and lignin (80%) as a promoter of metal implant and bone tissue integration. An intramedullary Schanz pin was implanted in both tibias of fifteen bitches. In the left tibia, the pin was coated with the biomaterial at the time of surgery. Marrow cavity was also filled with the biomaterial. Right limb did not receive the biomaterial, then constituting the control group. Tibias were harvested from five animals at 8, 60 and 150 days after surgery; three of them were analyzed by histological and biomechanical assessment and the two remaining tibias by X-ray diffraction. Results showed that the biomaterial is biocompatible, with osteoconductivity and osseointegration properties. Histological analysis and diffractograms showed the presence of hydroxyapatite in samples in all periods, although the presence of organic material of low crystallinity was variable. There was no statistical difference in the forces required for removal of the biocompatibility, osteoconductivity and osseointegration, it was not able to promote a better intramedullary pin anchorage.

RESUMOO artigo discute as ideias apresentadas pelo filósofo francês Jacques Rancière em O Mestre Ignorante (1987/2002) quanto a suas possíveis relações com a produção e circulação de livros didáticos para o ensino básico. Particularmente, observa-se como o livro didático pode reforçar o que o autor chama de lógica da explicação, intensificando a hierarquia das inteligências e a condição de desigualdade em nome de uma igualdade ainda por vir, mas também como ele pode interromper essa lógica, funcionando como uma fonte mediadora de duas vontades a serviço de uma única inteligência: a que possibilita que tanto o professor como o aluno aprendam e ensinem aquilo que ainda não sabem. Como suporte para a discussão, referimo-nos a alguns trechos de editais do governo federal relativos à elaboração de coleções de livros didáticos de língua estrangeira moderna.

Published: October 2015

Objectives: to investigate the association between the scores of the patient safety climate and socio-demographic and professional variables.Methods: an observational, sectional and quantitative study, conducted at a large public teaching hospital. The Safety Attitudes Questionnaire was used, translated and validated for Brazil. Data analysis used the software Statistical Package for Social Sciences. In the bivariate analysis, we used Student's t-test, analysis of variance and Spearman's correlation of (α=0.05). To identify predictors for the safety climate scores, multiple linear regression was used, having the safety climate domain as the main outcome (α=0.01).Results: most participants were women, nursing staff, who worked in direct care to adult patients in critical areas, without a graduate degree and without any other employment. The average and median total score of the instrument corresponded to 61.8 (SD=13.7) and 63.3, respectively. The variable professional performance was found as a factor associated with the safety environment for the domain perception of service management and hospital management (p=0.01).Conclusion: the identification of factors associated with the safety environment permits the construction of strategies for safe practices in the hospitals.

Objectives: to analyze treatment adherence in heart failure (HF) patients followed up by the nursing staff at specialized clinics and its association with patients' characteristics such as number of previous appointments, family structure, and comorbidities.Methods: a cross-sectional study was conducted at two reference clinics for the treatment of HF patients (center 1 and center 2). Data were obtained using a 10-item questionnaire with scores ranging from 0 to 26 points; adherence was considered adequate if the score was ≥ 18 points, or 70% of adherence.Results: a total of 340 patients were included. Mean adherence score was 16 (±4) points. Additionally, 124 (36.5%) patients showed an adherence rate ≥ 70%. It was demonstrated that patients who lived with their family had higher adherence scores, that three or more previous nursing appointments was significantly associated with higher adherence (p<0.001), and that hypertension was associated with low adherence (p=0.023).Conclusions: treatment adherence was considered satisfactory in less than a half of the patients followed up at the two clinics specialized in HF. Living with the family and attending to a great number of nursing appointments improved adherence, while the presence of hypertension led to worse adherence.

Objective: to analyze the complications related to peritonitis and catheter exit-site infections, in patients on peritoneal dialysis at home.Method: quantitative and cross-sectional study, carried out with 90 patients on peritoneal dialysis at home, in a municipality in the Northeast region of Brazil. For data collection, it was used two structured scripts and consultation on medical records. Descriptive analysis and comparison tests among independent groups were used, considering p<0.05 as level of statistical significance.Results: by comparing the frequency of peritonitis and the length of treatment, it was found that patients over two years of peritoneal dialysis were more likely to develop peritonitis (X²=6.39; p=0.01). The number of episodes of peritoneal catheter exit-site infection showed association with the length of treatment (U=224,000; p=0.015).Conclusion: peritonitis and catheter exit-site infection are associated with the length of treatment.

Published: October 2015

Objectives: to determine how the immigration phenomenon influences the response to informal care in the domestic level through the caregiver activity, and to analyze the cultural dialogue established in the residential area of Murcia (Spain).Method: This is an ethnographic study, conducted in 26 informal immigrant caregivers. As data collection instruments, semi-structured interviews and participant observation were employed. MAXQDA-2 assisted content analysis was also applied.Results: the immigrant caregiver is the main consumer of traditional medicines, extending these health practices to her home group. A cultural dialogue is established on informal care, characterized by interculturalism and mutual adaptation.Conclusions: cultural hybridization was identified for informal caregivers, immigrants and cultural integration: new health care practices and cultural behaviors in informal systems. There is a transformation in the roles of family members attended in domestic environments, increasing quality of life and self care. They represent an alternative to medicalization, promoting self-management of health.

Published: October 2015

Objective: to identify experiences and feelings on the organ donation process, from the perspective of a relative of an organ donor in a transplant unit.Method: this was exploratory research using a qualitative approach, performed with seven family members of different organ donors, selected by a lottery. Sociodemographic data and the experiences regarding the donation process were collected through semi-structured interviews. The language material was transcribed and submitted to content analysis.Results: poor sensitivity of the medical staff communicating the relative's brain death - the potential donor - and the lack of socio-emotional support prior to the situation experienced by the family was highlighted by participants.Conclusions: the study identified the need to provide social-emotional support for families facing the experience of the organ donation process. From these findings, other care and management practices in health must be discussed to impact the strengthening of the family ties, post-donation, as well as the organ procurement indexes.

Published: October 2015

Objective: To estabilish a regional list for nursing research priorities in health systems and services in the Region of the Americas based on the concepts of Universal Access to Health and Universal Health Coverage. Method: five-stage consensus process: systematic review of literature; appraisal of resulting questions and topics; ranking of the items by graduate program coordinators; discussion and ranking amongst a forum of researchers and public health leaders; and consultation with the Ministries of Health of the Pan American Health Organization's member states. Results: the resulting list of nursing research priorities consists of 276 study questions/ topics, which are sorted into 14 subcategories distributed into six major categories: 1. Policies and education of nursing human resources; 2. Structure, organization and dynamics of health systems and services; 3. Science, technology, innovation, and information systems in public health; 4. Financing of health systems and services; 5. Health policies, governance, and social control; and 6. Social studies in the health field. Conclusion: the list of nursing research priorities is expected to serve as guidance and support for nursing research on health systems and services across Latin America. Not only researchers, but also Ministries of Health, leaders in public health, and research funding agencies are encouraged to use the results of this list to help inform research-funding decisions.

Published: October 2015

At least 251 mammal species are recorded for the Brazilan cerrado, which, therefore, is the third richest Brazilian biome. Most mammal surveys in Brazilian cerrado result from studies performed opportunistically and in short time periods. The aims of the present study were (1) provide a checklist for the mammalian fauna based on a five-year sampling in Serra do Facão region, Southeastern Goiás state; (2) compare small non-flying mammals diversity in open and forest areas and (3) compare species diversity before and after the flood caused by a hydroelectric reservoir filling. The data was gathered in 19 sampling periods, from May 2008 to September 2013. We sampled open and forest habitats and captured non-flying small mammals with Sherman and Tomahawk live traps and pitfalls; bats were sampled with mist-nets; large mammals were recorded with camera traps, and by direct observations and track surveys in field. We found 20 species of small non-flying mammals, 10 species of bats and 33 species of larger mammals. Species diversity was greater for forest than open habitats, and was also greater before than after the complete reservoir filling. About 10% of the recorded species are included in the Brazilian official list of threatened species. The total richness represents 25% of all cerrado mammal fauna, highlighting the importance of this area for regional mammal fauna conservation.

ResumoContextoHá diferenças individuais no diâmetro da veia safena magna (VSM) em membros normais e doentes; sendo possível a identificação dessas alterações pelo ecocolor Doppler.ObjetivoAvaliar a associação da aplasia segmentar da VSM com a presença de varizes e/ou insuficiência da mesma em membros inferiores, usando o ecocolor Doppler em pacientes com clínica de doença venosa crônica (DVC).Métodos1.408 pacientes com queixas compatíveis de DVC de membros inferiores, sendo 1.286 do sexo feminino, com idade entre 17 e 85 anos, examinados com ecocolor Doppler. Foram incluídos aqueles com classificação CEAP clínica C0 a C4. Pela avaliação clínica, a amostra foi distribuída em grupo A, pacientes com varizes, e grupo B, aqueles sem varizes. O ecocolor Doppler determinou se havia aplasia da VSM pela análise do seu trajeto no compartimento safeno e presença de veias varicosas nos diferentes sítios. Para estatística, foram considerados os testes Qui-quadrado ou Exato de Fisher e uma análise de resíduos em tabelas, com nível de significância de 5%.ResultadosNo grupo A houve 479 (83,9%) de VSM insuficientes, 169 (38,2%) com aplasia e 71 (80,7%) com insuficiência e aplasia associadas. No grupo B, houve 92 (16,1%) de VSM insuficientes, 273 (61,8%) com aplasia e 17 (19,3%) com insuficiência e aplasia associadas.ConclusãoA aplasia segmentar da VSM ocorre mais em membros inferiores que não apresentam varizes e/ou insuficiência da mesma, mas considerando-se a presença da associação de aplasia e insuficiência, houve maior incidência no grupo de membros que apresentavam varizes.

Authors: Monção Maria Aparecida Guedes
Published: October 2015

Neste artigo discute-se o compartilhamento, entre famílias e educadores, da educação de crianças pequenas nas instituições de educação infantil. A investigação consistiu em uma pesquisa qualitativa, mediante estudo de caso de cunho etnográfico, realizado no período de 2010 a 2011, em um Centro de Educação Infantil - CEI - da rede municipal de São Paulo, que atende crianças de 0 a 4 anos. Os procedimentos metodológicos conjugaram observação participante, análise documental e entrevista semiestruturada com a equipe do CEI e com as famílias. Os resultados evidenciaram que a relação entre educadores e familiares é permeada por conflitos, sendo necessário, para a efetivação de uma relação de parceria, promover ações que garantam um diálogo permanente a respeito da educação coletiva das crianças.
