Published: April 2015

The aim of this study was to evaluate the knowledge of Community Health Agents (CHA) about the oral health/disease process, and compare the results between those who work in Family Health Teams (FHT), with and without Oral Health Teams (OHT). The participants in this study were 162 subjects, representing 66% of the total number of CHA in the municipality, and 81 of them are connected with Family Health Units (FHU) with OHT, and 81 CHS with FHUs without OHT. Data were collected from October to December 2013, by application of a questionnaire, containing personal and professional data, and 12 validated questions about knowledge of the oral health/disease process. The Mann-Whitney test was applied to verify differences between the groups. Statistically significant differences were verified between the groups of CHA when the total scores of questions about the oral health/disease process were analyzed (p < 0.0021). It was concluded that knowledge about the oral health/disease process, of the CHAs connected with a FHU with an OHT was better when compared with that of CHAs connected with a FHU without an OHT.

Published: April 2015

Introduction: The World Health Organization recommends breastfeeding for two years or more and advises against bottle feeding and pacifier use.Objective: Investigate the association between bottle feeding and pacifier use, and breastfeeding in the second half-year of life.Methods: Survey in a municipality of Rio de Janeiro state, in 2006, interviewing those responsible for 580 children aged 6-11 months. Bottle feeding and pacifier use, and variables which in the bivariate analysis were associated with the outcome 'absence of breastfeeding' (≥ 0.20), were selected for multiple analysis. Adjusted prevalence ratios were obtained by a Poisson regression model.Results: 40% of the children 6-11 months were not being breastfed, 47% used a pacifier and 57% used a bottle. Pacifier use (PR = 3.245; CI95%: 2.490-4.228) and bottle feeding (PR = 1.605; CI95%: 1.273-2.023) were shown to be strongly associated with the outcome, and also with: mother's low schooling (PR = 0.826; CI95%: 0.689-0.990); low birth weight (PR = 1.488; CI95%: 1.159-1.910); mother not being the baby carer (PR = 1.324; CI95%: 1.080-1.622); and increasing age of the baby in days (PR = 1.004; CI95%: 1.002-1.006).Conclusions: The use of pacifiers and bottles can reduce continued breastfeeding. Stronger discouragement of these artifacts should be adopted in public health policies.

Authors: Delalibera Mayra , Presa Joana , Coelho Alexandra , Barbosa António , Franco Maria Helena Pereira
Published: April 2015

The loss of a loved one can affect family dynamics by changing the family system and creating the need for family members to reorganize. Good family functioning, which is characterized by open communication, expression of feelings and thoughts and cohesion among family members, facilitates adaptive adjustment to the loss. This study conducted a systematic review of the literature on family dynamics during the grieving process. A search was conducted in the EBSCO, Web of Knowledge and Bireme databases for scientific articles published from January 1980 to June 2013. Of the 389 articles found, only 15 met all the inclusion criteria. The selected studies provided evidence that dysfunctional families exhibit more psychopathological symptoms, more psychosocial morbidity, poorer social functioning, greater difficulty accessing community resources, lower functional capacity at work, and a more complicated grieving process. Family conflicts were also emphasized as contributing to the development of a complicated grieving process, while cohesion, expression of affection and good communication in families are believed to mitigate grief symptoms.
Mortalidad evitable en los estados colindantes de la frontera México-Estados Unidos, 1999-2001 y 2009-2011
Authors: Botero Marcela Agudelo , Ramírez Raúl Sergio González , Jaramillo Ana María López
Published: April 2015

El objetivo de este artículo es medir el efecto de la mortalidad evitable en los cambios de la esperanza de vida en los estados colindantes de ambos lados de la frontera México-Estados Unidos entre 1999-2001 y 2009-2011. Los datos utilizados fueron los registros de mortalidad y los censos de población, provenientes de fuentes oficiales de cada país. Se estimaron tasas estandarizadas de mortalidad y se calcularon los años de esperanza de vida perdidos. Tanto en 1999-2001 como en 2009-2011 los estados pertenecientes a la frontera sur de Estados Unidos tuvieron tasas de mortalidad evitable más bajas que las observadas en los estados del norte de México. En la región fronteriza las muertes evitables representaron en promedio una ganancia de 0.19 años de vida para Estados Unidos y una pérdida de 0.47 años de vida para México. Los estados de la frontera México-Estados Unidos presentan rasgos comunes en sus perfiles de salud que hacen necesario abordar algunos problemas de forma global y otros considerando las particularidades de cada uno de ellos, con el fin de reducir las brechas y aumentar la equidad social, mediante estrategias que involucren acciones nacionales independientes y otras de coordinación transfronteriza.
The family's role as a support network for people living with HIV/AIDS: a review of Brazilian research into the theme
Authors: Silva Leonara Maria Souza da , Tavares Jeane Saskya Campos
Published: April 2015

The study of HIV transmission and the implementation of AIDS prevention actions recognize the importance of social networks in the transmission of the disease, the adherence to treatment and the quality of life of those infected. For this relevance there was a review of articles on social support networks to people living with HIV /AIDS available in the Virtual Health Library (VHL) were published in Brazil between 2002 and 2012. In this study 31 articles were used from journals covering the following áreas: Nursing (n = 15), Psychology (n = 6) and Science Health / Biomedica (n = 6), were included, which some principal authors were affiliated to higher education public institutions (n = 17). In relation to the methodology used, priority wasgiven to conducting: qualitative research (n = 18), cross-sectional studies (n = 19) and studies that involved talking to people living with HIV/AIDS (n = 13). Particular importance was placed on analytic categories related to: adherence to treatment (n = 6), the family (n = 4), vulnerability (n = 3) and support from social networks (n = 5). Within this paper we argue for more investments into studies that focus on the family, carers and their households, as well as deepening the theoretical study of the themes discussed and the use of developed theories for the analysis of Social Networks.

Published: April 2015

BACKGROUND: Resistance training has been used for the treatment of patients with peripheral artery disease (PAD). However, cardiovascular responses during this type of exercise have not been fully elucidated in these patients. OBJECTIVES: To analyze the cardiovascular responses during resistance exercise and to verify whether there are any correlations between these responses and disease severity or blood pressure levels in patients with PAD. METHODS: Seventeen PAD patients performed one set of 10 repetitions of knee extension exercise with an intensity of 50% of one repetition maximum. The responses of systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR) were continuously monitored using the finger photoplethysmography technique. The rate-pressure product (RPP) was obtained by multiplication of SBP and HR. RESULTS: During the resistance exercises there were significant increases in SBP (126 ± 14 vs. 184 ± 20 mmHg, p<0.001), DBP (68 ± 8 vs. 104 ± 14 mmHg, p<0.001), HR (76 ± 18 vs. 104 ± 30 bpm, p<0.001) and RPP (9523 ± 2115 vs. 19103 ± 6098 mmHg x bpm, p<0.001). A negative correlation was observed between relative change (Δ) in SBP and SBP at rest (r =-0.549, p=0.022). On the other hand, there was no relationship between Δ SBP and the ankle-brachial index (r=0.076, p=0.771). CONCLUSION: Increases in cardiovascular variables were observed during resistance exercise in PAD patients. The highest increases occurred in patients with lower SBP levels at resting.

Published: April 2015

BACKGROUND: The diagnosis of lymphedema can be obtained objectively by measurement methods, and also by subjective methods, based on the patient's complaint. OBJECTIVE: To evaluate inter-rater reliability of objective and subjective criteria used for diagnosis of lymphedema and to propose a lymphedema cut-off for differences in volume between affected and control limbs. METHODS: We studied 84 patients who had undergone lymphadenectomy for treatment of cutaneous melanoma. Physical measures were obtained by manual perimetry (MP). The subjective criteria analyzed were clinical diagnosis of lymphedema in patients' medical records and self-report of feelings of heaviness and/or increase in volume in the affected limb. RESULTS: For upper limbs, the subjective criteria clinical observation (k 0.754, P<0.001) and heaviness and swelling (k 0.689, P<0.001) both exhibited strong agreement with MP results and there was moderate agreement between MP results and swelling (k 0.483 P<0.001), heaviness (k 0.576, P<0.001) and heaviness or swelling (k 0.412, P=0.001). For lower limbs there was moderate agreement between MP results and clinical observation (k 0.423, P=0.003) and regular agreement between MP and self-report of swelling (k 0.383, P=0.003). Cut-off values for diagnosing lymphedema were defined as a 9.7% difference between an affected upper limb and control upper limb and a 5.7% difference between lower limbs. CONCLUSION: Manual perimetry, medical criteria, and self-report of heaviness and/or swelling exhibited better agreement for upper limbs than for lower limbs for diagnosis of lymphedema.

Published: April 2015

BACKGROUND: Chronic venous disease (CVD) is progressive and has a high prevalence in the economically active population. Its impact on the quality of life of affected individuals is poorly understood. OBJECTIVE: To test for correlations between the CEAP classification of CVD severity and CVD symptoms and quality of life of affected individuals. METHODS: We investigated 91 lower limbs in 59 patients with CVD (CEAP C1- C6). Patients were assessed with a Visual Analogue Pain Scale (VAPS), the Venous Clinical Severity Score (VCSS) and the SF-36 quality-of-life questionnaire. Spearman correlation coefficients were calculated. RESULTS: There were positive correlations between the CEAP classification and scores for VAPS (0.815, p <0.000), VCSS (0.937, p <0.000), and SF-36 in the dimensions Physical Functioning: -0.791, p <0.000; Role Physical: -0.839; p <0.000; Bodily Pain: -0.684; General Health: -0.617, p <0.000; Role Emotional: -0.691, p <0.000). There was no correlation with Vitality: -0.003, p=0.979; Role Social: -0.188, p=0.740 or Mental Health: -0.085, p=0.421. CONCLUSIONS: There were positive correlations between CEAP and both VAPS and VCSS. Chronic Venous Insufficiency progressively affects quality of life (SF-36). Physical and emotional aspects are more severe at later stages of CVD. Vitality, Mental Health and Role Social can be negatively impacted from the early stages of the disease.

Authors: Santos Isabel Cristina Ramos Vieira , Carvalho Eduardo Freese de , Souza Wayner Vieira de , Albuquerque Emídio Cavalcanti de
Published: April 2015

BACKGROUND: Diabetes and the problem of the diabetic foot specifically are a severe burden on the public healthcare system. Amputations caused by this condition are still common in our setting (Brazil), although the true magnitude of the problem is not known with certainty. Lower limb amputation rates have come to be seen as an indicator of the quality of preventative care of the diabetic foot. OBJECTIVE: To identify associations between amputations and factors related to people, to morbidities and to primary care received. METHODS: This was a cross-sectional study of a sample of 137 patients with diabetic feet admitted to a large hospital in the city of Recife, Pernambuco, Brazil. Logistic regression analysis was conducted. RESULTS: Associations with amputation were detected for the following variables: age over 60; resident of the Metro zone; income of three minimum salaries or less; presence of gangrene on admission; glycemia ≥ 126 mg/dL; smoking; not receiving information about results of glycemia testing; not having feet examined, and not being given guidance on caring for feet at consultations during the previous year. CONCLUSIONS: Factors related to Primary Care, such as time since onset of ulcers, information about results of glycemia testing and lack of guidance on how to care for their feet, were associated with occurrence of lower limb amputations.

Published: April 2015

BACKGROUND: Varicose veins of the lower limbs have a high prevalence worldwide. New treatment techniques have been developed with the objectives of improving patients' quality of life and reducing recovery times. OBJECTIVE: To evaluate patients with incompetent saphenous veins treated using conventional saphenectomy or radiofrequency ablation (RF), in terms of postoperative status. METHODS: From May 2012 to April 2013 146 varicose veins patients with saphenous insufficiency, 90 of whom were treated with conventional surgery (G1) and 56 with RF ablation (G2), were evaluated prospectively. RESULTS: In G1, 88.61% of patients complained of postoperative pain and needed to take analgesics, compared with 28.85% in G2 (p<0.05). Mean pain rating on an analog scale from 0 to 10 was 3.91±2.13 points for G1 and 1.76±3.01 points for G2 (p<0.05). Recovery periods ranged from 26.63±13.3 days to 18.26±19.37 days, for G1 and G2 respectively. Mean time taken to become totally asymptomatic was 66.78±60.9 days for G1 and 38.38±46.8 days for G2 (p<0.05). CONCLUSIONS: The RF treatment method caused less postoperative pain and resulted in earlier recovery, when compared to conventional saphenectomy.
Management and conduct of vascular diseases of the portal system
Authors: Cardoso Lenon , Pinheiro Thiago Cerizza , Scandiuzzi Maissa Marçola , Simoneti Fernanda Soares , Ilias Daniel , Moda Marlon , Borghesi Ronaldo Antônio
Published: April 2015

Aneurysms and thromboses of the portal vein are rare pathologies of the portal system that commonly follow an asymptomatic course. The vast majority of cases are diagnosed as incidental findings during imaging studies. Symptoms of aneurysms are the result of mass effects, while thrombosis symptoms are a function of the liver's ability to form a collateral circulation network in the thrombosis. The scant experience with such cases poses a dilemma for patient management and so the vast majority of authors choose an expectant approach with rigorous patient surveillance and only intervene in symptomatic patients. We report one case of an aneurysm of the portal vein and one case of portal vein thrombosis and discuss management and observation of these patients.

Authors: Melo Bruno Vieira , Tojal Priscilla Gabriela Moreira Dantas , Leal Flávia de Jesus , Couto Renata Cardoso
Published: April 2015

BACKGROUND: Wearing elastic compression stockings is of considerable significance for patients with chronic venous disease (CVD), since their physiological effect is to improve venous hemodynamic parameters, making them a good treatment option that can impact on patients' quality of life. OBJECTIVE: To assess quality of life in patients with chronic venous disease who do or do not wear elastic stockings. METHODS: This was a cross-sectional observational study assessing a sample of 50 CVD patients of both sexes, divided into two groups, one who wear elastic stockings and another who do not. Primary variables were the domains of the SF-36 (Medical Outcomes Study Short-form 36) and AVVQ (Aberdeen Varicose Veins Questionnaire) and secondary variables were: age; sex; physical activity; educational level; profession; wearing elastic stockings (frequency, pressure and type); elevation of lower limbs; itching and CEAP classification. The SF-36 and AVVQ quality of life questionnaires were administered to patients. Statistical significance was set at p<0.05. RESULTS: Wearing elastic stockings proved beneficial for the quality of life of people with chronic venous disease. For the AVVQ disease-specific questionnaire the greatest improvements were in overall score (p=0.0028) and the extent of varicosity domain (p=0.000). The SF-36 domains role emotional (p=0.017) and functional capacity (p=0.000) both improved. CONCLUSIONS: Wearing elastic stockings is an effective treatment for CVD that improves disease-specific quality of life and also leads to improvements in general quality of life.

Published: April 2015

This study aims to identify the primary problems faced by accounting professors both upon entry into the profession and during later phases. Thus, it seeks to answer the following research question: what are the problems perceived by accounting professors in Brazil during each phase of the professional life cycle? The data collection instrument was constructed based on the life cycles proposed by Huberman (2000) and the problems identified by Veenman (1984) and validated by a committee of experts (Delphi technique). The sample consisted of 574 Brazilian professors. The results indicate that the main problems faced by professors were the following: "lack of student motivation"; "heterogeneous classes"; "amount of administrative work"; "very large class size"; and "lack of time". It was also found that these problems tend to be the same during all phases of the professorial life cycle. However, these problems are more intense upon entry into the career; their importance decreases in each phase. It was also found that professors working for public versus private institutions confronted different problems. The large amount of administrative work and the lack of guidance by the higher education institution (HEI) are typical problems of public institutions. The degree level achieved by professors is also sensitive to the type of problems that they face. In other words, the lack of opportunities for additional training, the lack of HEI guidance, and the knowledge of academic standards are issues that most directly affect professors with lower professional degrees, whereas the lack of time and the large amount of administrative work are problems faced with greater intensity by professors with higher degrees.

Published: April 2015

Este trabalho discute, sob a ótica da Teoria Antropológica do Didático, o modo como é proposto o estudo da área de figuras geométricas planas no currículo de Matemática do Programa Projovem Urbano e a relação entre esse estudo e os princípios que regem o referido Programa. Para tanto, foram analisados documentos como o Guia de Estudo, o Projeto Pedagógico Integrado e as Propostas Curriculares para a Educação de Jovens e Adultos. Percebemos que a Organização Matemática predominante é o cálculo da área de retângulos, por meio do uso da fórmula, justificada pela contagem de quadradinhos, o que se aproxima da abordagem no ensino regular. Por outro lado, o uso frequente do contexto da construção civil aponta para a conexão com a dimensão da qualificação profissional, preconizada nos princípios que regem o Programa Projovem Urbano.
Envolvimento dos Alunos em Atividades de Modelagem Matemática: relação com o saber e possibilidades de ação
Authors: Campos Ilaine da Silva , Araújo Jussara de Loiola
Published: April 2015

Apresentamos, neste artigo, resultados de uma investigação que buscou compreender o envolvimento de dois alunos, integrantes de um grupo, em uma atividade de modelagem matemática, a partir da relação que eles estabelecem com o saber matemático. Apoiadas no referencial teórico de Bernard Charlot, da relação com o saber, e utilizando uma abordagem qualitativa, analisamos três episódios em que o grupo está desenvolvendo um projeto de modelagem matemática. Além dos episódios, entrevistas possibilitaram entender aspectos referentes ao envolvimento dos alunos. Nossa análise deu origem à construção do conceito de possibilidades de ação. Como resultado, percebemos que a relação de cada aluno com a Matemática desempenha um papel decisivo em suas possibilidades de ação e que seu envolvimento em atividades de modelagem pode ser compreendido não apenas como as ações efetivamente realizadas, mas também como aspossibilidades de ação vislumbradas por eles.

Authors: Barragués José I. , Morais Adolfo , Guisasola Jenaro
Published: April 2015

La investigación Educativa ha señalado la necesidad de una mayor investigación acerca de los componentes del conocimiento del profesorado, que deben ir más allá del mero conocimiento del contenido matemático. El denominado Conocimiento Profesional del Profesorado incorporaría aspectos relacionados con la propia enseñanza de la disciplina, las perspectivas de los profesores, la historia, las dificultades de los estudiantes etc. Este trabajo aborda los siguientes temas de investigación: Conocimiento Profesional del profesorado sobre Probabilidad, Epistemología e Historia de la Teoría de la Probabilidad y Didáctica de la Teoría de la Probabilidad. Se aborda en primer lugar el problema de identificar los componentes de este Conocimiento Profesional que serán de utilidad al profesorado universitario de Teoría de la Probabilidad para el diseño de secuencias de enseñanza-aprendizaje; y, en segundo lugar, se estudia en qué medida tales componentes son tenidos en cuenta en la enseñanza universitaria. Se ha realizado un análisis fenomenológico de la Teoría de la Probabilidad, incluyendo la fenomenología histórica, y se han estudiado, mediante un cuestionario escrito y entrevistas personales, las propuestas de enseñanza de un grupo de profesores universitarios de estudios de Ingeniería. El análisis ha identificado los siguientes aspectos que deben formar parte del Conocimiento Profesional: el planteamiento de situaciones problemáticas para la introducción de los conceptos; la discusión de las diferentes formulaciones conceptuales de la Probabilidad y sus problemáticas históricas; las implicaciones entre la Ciencia, la Técnica y la Sociedad destinadas a mejorar el interés de los estudiantes; y la toma en consideración de las concepciones alternativas de los estudiantes. El estudio de las propuestas de enseñanza revela una ausencia de estos componentes en el Conocimiento Profesional de los profesores investigados, lo cual evidencia la necesidad de programas de formación que presten atención a los resultados de la investigación en Educación Matemática.

Published: April 2015

Este estudo qualitativo objetivou compreender os significados que os trabalhadores da enfermagem atribuem ao próprio processo de envelhecimento no mercado de trabalho, identificando implicações na saúde individual e familiar. Foi utilizado o método da história oral temática, com vinte trabalhadores da enfermagem de hospital público na cidade de Marília, São Paulo. Na análise, emergiram três categorias: história do trabalho na vida, história sobre saúde e adoecimento no e/ou pelo trabalho e história do envelhecimento no e/ou pelo trabalho. Depreendemos que o trabalho ocupa lugar de destaque; além de garantir a subsistência, propicia a participação na sociedade. Encontramos relatos de insatisfação com o trabalho, relacionada principalmente à maneira como ele está organizado. Concluímos que o trabalho continua sendo uma atividade importante durante toda a vida, e o ambiente e a forma como o trabalho está organizado influenciam no processo de envelhecimento. O grande desafio para a enfermagem é formular proposições que impliquem real melhoria da condição dos seus trabalhadores.
PERCEPÇÃO DO TRABALHO DOCENTE EM UMA UNIVERSIDADE DA REGIÃO NORTE DO BRASIL
Authors: Lago Rozilaine Redi , Cunha Bruna Souza , Borges Maria Fernanda de Sousa Oliveira
Published: April 2015

Buscou-se conhecer a percepção da experiência do trabalho docente em cursos de saúde de uma universidade federal da região Norte do Brasil. Utilizando-se abordagem qualitativa, foram entrevistados seis docentes de cursos de saúde dessa universidade, cujos dados foram submetidos à análise de conteúdo. Predominaram mulheres na função docente, e a valorização dessa função como vínculo estável de trabalho, fonte de rendimentos e função social. No trabalho docente, a maioria se concentra no desenvolvimento de habilidades técnico-científicas dos alunos, expressando a necessidade da qualificação contínua e apoio institucional insuficiente. As relações pessoais desses docentes com alunos e outros professores e técnico-administrativos são reconhecidamente mediadoras da qualidade do processo de ensino-apren-dizagem e trabalho. Quanto à saúde, a maior parte se sente vulnerável e desgastada, principalmente em aspectos psicoemocionais, o que influencia as suas relações sociais dentro e fora do ambiente de trabalho. Embora o exercício profissional tenha sido identificado como fonte de estabilidade, realização pessoal e financeira, destacam-se a precariedade e a sobrecarga de trabalho, que tendem a induzir sofrimento e adoe-cimento. Esta reflexão entre docentes, movimentos sindicais e instituições de ensino pode subsidiar ajustes institucionais, legais, curriculares e sociais para melhorar o processo de ensino-aprendizagem e a qualidade de vida dos docentes.
A AÇÃO DOS AGENTES COMUNITÁRIOS DE SAÚDE E O TRABALHO VIVO EM ATO
Authors: Piccinini Carlos Augusto , Silva Rosane Azevedo Neves da
Published: April 2015

Este artigo analisa a singularidade da ação dos agentes comunitários de saúde em sua circulação pelo território, no município de Porto Alegre, no Rio Grande do Sul. Considerou-se que os encontros entre agentes e território extrapolam as prescrições e expectativas das políticas de saúde. Problematizou-se a produção de uma imagem idealizada dos agentes, no qual são vistos como a 'mola propulsora' das transformações esperadas da Atenção Básica. Ao se analisar a complexidade das demandas presentes em seu cotidiano de trabalho, destacou-se a multiplicidade de estratégias de cuidado produzidas pelos agentes comunitários. A singularidade de cada território, das equipes de saúde e da gestão, entre outras numerosas variabilidades, pressiona os agentes e os demais trabalhadores das equipes da Estratégia Saúde da Família a encarar uma realidade bastante distinta do que se supõe. Destacou-se, portanto, a importância de se produzir uma posição crítica e reflexiva, colocando em questão os limites e possibilidades dessa prática, a fim de potencializar as estratégias de cuidado ali existentes.
A new species of Chaetostoma, an armored catfish (Siluriformes: Loricariidae), from the río Marañón drainage, Amazon basin, Peru
Authors: Salcedo Norma J. , Ortega Hernán
Published: April 2015

A new species of Chaetostoma was found in mountain tributaries of the río Marañon, Peru. The new species differs from all described congeners by having a tuft of odontodes, surrounded by naked skin, in the middle of each trunk lateral dermal plate, and in bearing more than 20 hypertrophied evertible odontodes on three cheek plates vs. evenly distributed odontodes on the whole surface of each dermal plate, and in bearing fewer than 20 hypertrophied evertible odontodes on three cheek plates in all other Chaetostoma species. The new species resembles two Cordylancistrus species in the presence of a tuft of odontodes in the middle of each trunk lateral dermal plate, but it exhibits a naked snout (vs. snout covered with plates in Cordylancistrus) and one uniquely derived character present in some species of Chaetostoma - a short, slender fourth branchiostegal ray.

Published: April 2015

Rhamdia quelen (silver catfish) and Leporinus obtusidens (piava) were exposed to a commercial formulation Roundup(r), a glyphosate-based herbicide at concentrations of 0.2 or 0.4 mg/L for 96 h. The effects of the herbicide were analyzed on the alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities and glucose in plasma, glucose and protein in the mucus layer, nucleotide hydrolysis in the brain, and protein carbonyl in the liver. The parameters were chosen, owing to a lack of information concerning integrated analysis, considering oxidative damage parameters, liver damage, and effects on the mucus layer composition and triphosphate diphosphohydrolase (NTPDase) activities. Plasmatic glucose levels were reduced in both species, whereas the transaminase activities (ALT and AST) increased after exposure to the herbicide. Herbicide exposure increased protein and glucose levels in the mucus layer in both species. There was a reduction in both NTPDase and ecto-5'-nucleotidase activity in the brain of piava, and increased enzyme activity in silver catfish at both concentrations tested. The species showed an increase in protein carbonyl in the liver after exposure to both concentrations of the glyphosate. Our results demonstrated that exposure to Roundup(r) caused liver damage, as evidenced by increased plasma transaminases and liver protein carbonyl in both of the fish species studied. The mucus composition changed and hypoglycemia was detected after Roundup(r) exposure in both species. Brain nucleotide hydrolysis showed a different response for each fish species studied. These parameters indicated some important and potential indicators of glyphosate contamination in aquatic ecosystems.

The troglobitic electric fish Eigenmannia vicentespelaea, endemic to a single cave-system and included in the Brazilian Red List of Threatened Fauna, was studied in relation to population densities and habitat. For comparison, we used the epigean species, E. trilineata. We verify if the population densities recorded for E. vicentespelaea follow the pattern observed for other subterranean fishes; if there are seasonal fluctuations in these densities and which environmental variables explain the densities variation. We estimated abundances and population densities during three consecutive dry seasons concomitant with habitat description and physicochemical variables measurements. For E. vicentespelaea: in six stream reaches in the São Vicente II cave. For E. trilineata: from counts of active fish in rio da Lapa. The mean population density recorded for E. vicentespelaea is considered low (0.17 ind.m-2), similar to those of E. trilineata (0.13 ind.m-2), without significant differences between the years, but with marked fluctuations during dry seasons within each year, suggesting seasonality. Estimated population size of E. vicentespelaea is considered low (270 individuals in average). Depth, water current and substrate, allied to plant debris explain better the variation of densities. Urgent actions for E. vicentespelaea conservation include protection of headsprings in Terra Ronca State Park.

Vulvovaginal candidiasis (VVC) in HIV-infected women contributed to the impairment of their quality of life. The aim of this study was to evaluate the effect of highly active antiretroviral therapy (HAART) use on the vaginal Candida spp. isolation in HIV-infected compared to HIV-uninfected women. This cross-sectional study included 178 HIV-infected (HIV group) and 200 HIV-uninfected women (control) that were studied at the Specialized Assistance Service (SAE) for sexually transmitted diseases (STD)/AIDS of the city of Maringá, Brazil, from April 1 to October 30, 2011. The yeasts were isolated and identified by phenotypic and molecular methods. The in vitro antifungal susceptibility to fluconazole, itraconazole, nystatin and amphotericin B was tested by the reference microdilution method. Higher frequencies of total vaginal Candida spp. isolation were found in the HIV-infected group than in the control group. However, both groups showed a similar frequency of colonization and VVC. Although C. albicans was the most frequent and sensitive to azolics and polyenes in both HIV-infected and uninfected women, the emerging resistance of C. glabrata to amphotericin B in the HIV-infected women was observed. Although higher frequency of vaginal Candida spp. isolation had been observed in the HIV-infected than in HIV-uninfected women, colonization and VVC showed similar frequency in both groups, indicating that HAART appears to protect against vaginal colonization and VVC.

This study aimed to assess the exposure of free-living jaguars (Panthera onca) to Leptospira spp. and Brucella abortus in two conservation units in the Pantanal of Mato Grosso, Brazil. The presence of antibodies in blood samples of eleven jaguars was investigated using autochthonous antigens isolated in Brazil added to reference antigen collection applied to diagnosis of leptospirosis by Microscopic Agglutination Test (MAT). The Rose Bengal test was applied for B. abortus antibodies. Two (18.2%) jaguars were seroreactive for the Leptospira spp. antigen and the serovar considered as most infective in both animals was a Brazilian isolate of serovar Canicola (L01). All jaguars were seronegative for B. abortus. These data indicate that the inclusion of autochthonous antigens in serological studies can significantly increase the number of reactive animals, as well as modify the epidemiological profile of Leptospira spp. infection.

Leptospira interrogans has been identified to cause leptospirosis, a widespread zoonotic disease that has been identified in domestic and wild animals. This work analyzed kidneys from two species of wild rodents from the state of Campeche, Mexico. Analyses were made by PCR using specific primers for detection of Leptospira interrogans DNA. The rodent species that tested positive were Heteromys gaumeri and Ototylomys phyllotis, both of which are new hosts for the bacteria in Southeastern Mexico. These records provide new insights into the disease’s transmission that should be studied carefully in order to identify other potential host species, including humans, which are at risk of becoming infected if they are in contact with infected wildlife.

In order to investigate the validity of critical velocity (CV) as a noninvasive method to estimate the lactate minimum velocity (LMV), 25 youth runners underwent the following tests: 1) 3,000m running; 2) 1,600m running; 3) LMV test. The intensity of lactate minimum was defined as the velocity corresponding to the lowest blood lactate concentration during the LMV test. The CV was determined using the linear model, defined by the inclination of the regression line between distance and duration in the running tests of 1,600 and 3,000m. There was no significant difference (p=0.3055) between LMV and CV. In addition, both protocols presented a good agreement based on the small difference between means and the narrow levels of agreement, as well as a standard error of estimation classified as ideal. In conclusion, CV, as identified in this study, may be an alternative for noninvasive identification of LMV.

The level of variability in psychomotor behavior and the use of several distinct sets of equipments in Reaction Time (RT) assessments might jeopardize the validity and reliability of such measures. This study presents the development and verification of Emboici Robot-a robot capable of performing accurate RT assessments consisting of response to a visual stimulus by pressing a button-whose purpose is to measure the accuracy of RT assessments. We evaluated the accuracy and precision on four different days, each providing 300 measurements. These assessments generated a RT of 46.95ms (+6.04). No significant effects were found in the RTs obtained and, as a result, there is evidence that the Emboici Robotis stable, reliable, and precise. The robot can be a viable solution for verifying precision and accuracy of any given software with simple RT assessments with visual stimulus requiring as response the pressing of a button or key.
UlyssesPianola
Authors: Saint-Amour Paul K.
Published: April 2015

Now that phonography is established as the cardinal regime of audio recording, storage, and playback in studies of sonic modernity, a coeval sound-reproduction technology merits attention—the pianola, or player piano. The instrument is a pneumatic reading machine: it scans binary machine code from perforated paper rolls and translates it into acoustic events while prompting song with its scrolling lyrics. Revisiting Derrida's “Ulysses Gramophone” (1984) thirty years on, this essay finds there a proleptic critique of the gramophonocentrism Derrida's piece has helped underwrite in sound studies. The essay then turns to an extended reading of Joyce's novel, one of several modernist works that feature the pianola in their self-conceptualization.Ulysses'spianola at once incarnates the novel's virtuosic recall of its own language and insists on the ineliminable role of exchange and of the gendered and laboring body in any performance of stored data.
Helen's Gifts
Authors: Campbell Timothy
Published: April 2015

I'm struggling now, trying to write, to say anything, to follow the command “write it!” what i really need is an e-mail from Helen, telling me to sit down, to say what it is that I want to say and then to go about saying it. She would probably give me an ideogram, direct me to a page of Ernest Fennollosa's The Chinese Written Character as a Medium for Poetry, then add how much she was looking forward to seeing the essay in print, on real paper, out there in the world. She would also, perhaps by way of closing, remind me that writing was a practice of making oneself vulnerable, and that wisdom wasn't going to come uninvited if you didn't let go of the need for some security.
Federating the Modern Spirit: The 1922 Congress of Paris
Authors: Hentea Marius
Published: April 2015

The aim of the ill-fated 1922 Congress of Paris, an international conference organized by André Breton, was to diagnose the sources of the “modern spirit.” Although the congress had ambitious international goals, it was brought down by a remark with xenophobic connotations. Largely remembered today as the death knell of Paris Dada—the public fight between Tristan Tzara and Breton meant not only that the congress never took place but also that Paris Dada was dissolved—the congress's failure stemmed from the tensions involved in selfconsciously deining modernism. Arguing that ambivalence over the concept shaped the main participants' understanding of the congress, I read the congress as a concrete manifestation of the impulse to federate the arts in post-World War I France.
Djuna Barnes and the Geriatric Avant-Garde
Authors: Herring Scott
Published: April 2015

Though her publications were slight after she permanently moved to Greenwich Village, in New York City, in 1940, Djuna Barnes labored over scores of literary and nonliterary typescript drafts from the 1940s to the 1980s. This unpublished artwork constitutes a geriatric avant-garde that deepened her earlier investments in modernist aesthetics. Archived documents record the elderly writer performing the principles of high modernism—innovation, experimentalism, and novelty—across an unprecedented array of genres, such as the poem, the pharmacy order, the grocery list, the medicine regimen, the memo, and personal correspondence. This article reassesses gerontophobic depictions of Barnes as an aged recluse who lived a creatively fruitless late life. The underex-plored works of her senior years are a unique version of what Eve Kosofsky Sedgwick calls “a senile sublime.”
