Surgery or surgical defolation in ‘Grand Naine’ banana in the control of black Sigatoka in the state of Rio de Janeiro
Authors: Jiménez Jose Leonardo Santos , Brioso Paulo Sergio Torres
Published: October 2018

Abstract ‘Grande Naine’ banana (Musa acuminata - AAA) in the municipality of Angra dos Reis (RJ) has been affected by the Black Sigatoka agent, fijiensis Mycosphaerella(current name Pseudocercospora fijiensis); causing losses to local producers, mostly small producers and low-income producers. Since Black Sigatoka was reported in the mentioned municipality, it was aimed to determine control efficiency through surgical measurement or surgical defoliation and to evaluate its effect on banana productivity characteristics. For this purpose, treatment was designed in the form of completely randomized blocks containing three blocks, each block with five plants with treatment (Surgery) and five plants without treatment (Control), in a total of 30 plants with fungal infection. Treatments were performed every 15 days with monthly severity assessments (Weighted Mean of Infection - MPI) by the method of Stover modified by Gauhl. The results obtained at the end of the trial showed significant differences in all variables (Severity, youngest leaf spotted, bunch weight and fruit size), and treatment with surgery provided reduction in severity (MPI) around 58%, thus confirming that plants received adequate treatment according to the results obtained for this methodology, and, contributing to the increase of the healthy leaf area in the youngest leaves, whereas in plants without surgery (Control), severity increased by 14.8% in comparison to the initial MPI evaluation, consequently having a smaller healthy leaf area for the accomplishment of photosynthesis and other physiological processes. In production variables bunch weight, fruit size and number of fruits, differences were significant (Pr> F = 0.0001), reaching an increase in yield of up to 300% when compared to Control. It is therefore an effective method for the control of phytopathogen black sigatoka unpublished in the state of Rio de Janeiro and that will bring direct benefits for Family Agriculture in the region of incidence of this banana disease.

Abstract The aim of the present work was to study Argentinean natural clays with different modifications and their use as desiccants. To this end, bentonite clays collected from different regions were characterized and modified by heat treatment and calcium addition, and the desiccant capacity, in the form of powder and pellets, was studied. In addition, the hydration degree reversibility of these materials was estimated. The mineralogical and structural characterization was performed by X-ray diffraction, Fourier-transform infrared spectroscopy, differential thermal analysis, and thermogravimetric analysis. The textural characterization was performed by adsorption-desorption of N2, chemical composition by X-ray fluorescence and cation exchange capacity. The water adsorption was determined at 25 °C between 11-98% relative humidity. The results indicated that the desiccant power has a close relationship with the degree of clay purity, drying of the sample and the method of calcium incorporation.

Abstract Passion fruits species presents a larger economic importance for in natura consumption and industry. The main way to propagate these species is by seeds; however, the aril presence and environmental conditions may inhibit the seeds germination. In this sense, the objective of this study was to evaluate the effect of aril removal methods and light conditions on P. edulis var. flavicarpa seeds quality and germination. There were used five methods to remove the seeds aril: (1) friction on steel mesh sieve for 5 minutes; (2) friction with coarse sand on steel mesh sieve for 5 minutes; (3) immersion in lime solution at 10% (w/v), for 30 minutes; (4) fermentation in sugar solution at 10% (w/v), during 48 hours; and (5) natural pulp fermentation, during five days. The seeds were submitted to germination test at darkness and lightness, as well as, to length seedlings and emergence test. Regardless the aril removal method, the germination percentage was lower at lightness than darkness highlighting the natural pulp fermentation treatment, which presented 86% of seeds germinated. On the other hand, the aril removal methods did not affect the seedlings emergence, with emergence percentages ranged from 88 to 94%.

Abstract In Brazil, given its privileged hydrology, the unexplored economic use of water resources has many dimensions, such as hydroelectric power. This energy will face increasingly rigorous social and environmental impact assessments (40% of potential is located in the Amazon region). Hydropower inventory studies conducted over decades, with solutions such as ecological river flows, that flood smaller areas and reduce natural river flows modifications, are being reviewed. The river extension from dam to the point where the waters are returned after the powerhouse is known as the Reduced Flow Stretch (RFS). Even mega-projects, such as the 11.3 GW Belo Monte dam, are designed with deviating flows reaching an astounding 13,000 m 3/s (excavated material higher than Panama Canal). RFS requires to be carefully studied to achieve appropriate ecological flows, since RFS flows increased reduces the plant's electricity production to the same installed capacity. Balancing RFS requirements and hydroelectric power remains a challenge and, clearly, there is no consensus. Here, we performed an analysis of the main environmental impacts caused by RFS requirements, considering the multiple water use specific for each dam site. The natural variability of river flows provides diversity of habitats and maintains the richness and complexity of biological communities. Therefore, the present study has great ecological, social and economic relevance, since proper evaluation of the RFS requirements avoids potential destabilization of biological communities and even loss of biodiversity. This type of arrangement was more common in dams located in headwaters of rivers, as in the slopes of the Andes mountain range, and in regions like the Alps. There are many hydroelectric plants in South America and Europe that have this type of arrangement of engineering works. But the times are different and the environmental impacts have to be better evaluated. A final aspect also involves the maintenance of ecological flows downstream of dams. Regularization reservoirs need to keep downstream, even if they do not have a TVR, adequate flows that represent minimally the seasonality of the river, with floods and droughts, that propitiate the maintenance of the ecosystems downstream. There are cases such as the Sobradinho Plant in the São Francisco River that has been much questioned in this regard, especially when the climate is changing in the basin, with long periods of drought, and with increasing water use. So this is a very important and increasingly current issue.

RESUMO Os tumores da bainha perineural são pouco frequentes em animais domésticos. Relata-se o caso de um cão, sem raça definida, de cinco anos, fêmea, com histórico de aumento de volume em região retrobulbar do globo ocular direito (GOD) havia três semanas. Ao exame clínico, constatou-se a presença de uma neoformação retrobulbar direita com deslocamento do globo ocular cranialmente. Aos exames realizados durante o internamento, não foi possível localizar a origem e a extensão da neoformação. O animal veio a óbito por parada cardiorrespiratória e foi encaminhado para a necropsia. À avaliação macroscópica, observou-se neoformação esbranquiçada fixada à base do crânio em região selar, com possível origem no terceiro (III) par de nervos cranianos, a qual se infiltrava no encéfalo na altura do hipotálamo, estendia-se caudalmente em direção ao tronco encefálico e cranialmente à órbita direita, comprimindo, assim, o GOD. Microscopicamente consistia de feixes curtos entrelaçados ou enovelados de células fusiformes com pleomorfismo discreto a moderado, alternando-se a áreas de necrose multifocalmente, compatível com tumor da bainha perineural. Ao exame imuno-histoquímico, apresentou marcação fraca para S100 e GFAP e marcação positiva para vimentina, o que indica caráter maligno.

ABSTRACT The aim of this study was to evaluate in vitro and in vivo the effect of sodium dodecyl sulfate (SDS) on the caprine lentivirus (CLV) in colostrum and milk. This was performed to develop a practical and efficient method of blocking the lactogenic transmission of the virus. In the in vitro experiment, colostrum and milk were treated with 0.25%; 0.50% and 1% SDS. Then, somatic cells of colostrum and milk were submitted to co-culture with caprine synovial membrane cells (CSM). In the in vivo test, goats were fed with colostrum and milk provided from CLV-positive goats treated with SDS in the same concentrations used in the in vitro experiment. Animals were tested by nested polymerase chain reaction (nPCR) and Western blot (WB) assays. In the in vitro experiment, inhibitory activity against CLV without inactivation occurred in colostrum with all SDS concentrations. However, concentrations of 0.25 and 0.5% SDS presented only inhibitory activity against CLV in milk cells, and 1% concentration provided inactivation of the virus. In the in vivo tests, none of the three concentrations of SDS was effective in inactivating LVC in colostrum or goat milk, which was confirmed by seroconversion and presence of proviral DNA in animals afterwards.

ABSTRACT This study aimed to evaluate the effect of the 0.15% sodium hyaluronate (SH) and of 0.5% carboxymethylcellulose (CMC) on tear film breakup time (TFBUT) in 10 healthy dogs and in 32 eyes of dogs with keratoconjunctivis sicca (KCS). In addition, the goblet cell density (GCD) of this population was quantified. TFBUT was assessed at baseline and at different time points following the instillation of SH and CMC. KCS was graded as mild, moderate, and severe. GCD were quantified from conjunctival biopsies. The number of GCD differed significantly between patients with mild and moderate KCS (P<0.01). TFBUT of healthy dogs increased only for 1 minute after treatment with SH (P<0.01). Regarding baseline and treatments, SH significantly increased TFBUT for up to 30 minutes on the ocular surface, in comparison to CMC, in all categories of KCS (P<0.01). TFBUT and GCD correlated positively when the healthy and diseased eyes were grouped (r=0.41, P=0.006). It can be concluded that in dogs with KCS, SH lasts longer periods on the ocular surface than CMC, but such agents does not increase TFBUT in healthy dogs. Additionally, tear film stability tends to reduce in a linear fashion from the mild to severe form of KCS.

RESUMO Objetivou-se verificar se a utilização do modelo autorregressivo (MAR) é adequada para obtenção de parâmetros genéticos para produção de leite no dia do controle (PLDC) de bovinos leiteiros da raça Gir. Foram analisados 125.191 registros de produções diárias, nas três primeiras lactações, por meio dos modelos de repetibilidade (MREP) e MAR. No MREP, foi considerado o efeito de ambiente de curto prazo; no MAR, foi considerado, também, o efeito de ambiente de longo prazo. Os modelos foram comparados por meio do logaritmo da função de máxima verossimilhança ( − 2 log L ). A herdabilidade estimada pelo MREP foi 0,18; no caso do MAR, as estimativas para primeira, segunda e terceira lactações foram 0,32, 0,28 e 0,26, respectivamente. A estimativa de autocorrelação dos componentes de variância de longo prazo foi próxima de zero, e as de curto prazo foram de alta magnitude para primeira (0,79), segunda (0,79) e terceira (0,81) lactações. Logo, a influência do ambiente de curto prazo dentro de cada lactação não é a mesma. O valor de − 2 log L mais próximo de zero foi obtido para o MAR (-294.884,7778) em relação ao MREP (-329.266,4810). Assim, o MAR é adequado para obtenção de estimativas de parâmetros genéticos para PLDC nas três primeiras lactações de bovinos leiteiros.

Published: October 2018

ABSTRACT Objective Nutritional diseases such as metabolic syndrome, cardiovascular disorder, chronic inflammation or even cancer are observed in people who sustain their lifestyle by Western diet due to high calorie intake. The origin of these diseases are the degraded deoxyribonucleic acid structure. In this study, we investigated whether Western diet produced endogenous oxidative deoxyribonucleic acid damage, apoptosis or inflammation. Methods Twenty-eight male Wistar rats, aged 10-12 weeks, were divided into four groups. The rats in control group received the standard diet and the remaining rats were given one of the following three diets for four weeks: a high-fat diet containing 35% fat, a high-sucrose diet containing 69% sucrose and Western diet comprising both two types of diets. After treatment the serum 8-hydroxy-2-deoxyguanosine, poly (adenosine diphosphate ribose) polymerase-1, chitinase-3-like protein 1, soluble urokinase-type plasminogen activator receptor, Fas ligand and cytochrome c levels were measured. Results It was observed no changes in the serum soluble urokinase-type plasminogen activator receptor, Fas ligand and cytochrome c levels whereas a statistically significant increase in the serum 8-hydroxy-2-deoxyguanosine, poly (adenosine diphosphate ribose) polymerase-1 and chitinase-3-like protein 1 levels were found only in rats that were given Western diet. Conclusion The findings show that Western diet produced endogenous oxidative deoxyribonucleic acid damage, which then increased serum poly (adenosine diphosphate ribose) polymerase-1 levels, eventually leading to inflammation.

ABSTRACT Objective To evaluate the effect of protein intake on body weight gain at pregnancy. Methods A cross-sectional study was carried out with 297 women who delivered a child at the maternity ward of Municipal Hospital Leonel de Moura Brizola in Mesquita city in the state of Rio de Janeiro. Sociodemographic and anthropometric data were collected through the use of a structured questionnaire at first week after delivery. Food intake was assessed by a food frequency questionnaire. Protein intake per kilogram of body weight (g/kg per day) during pregnancy was categorized as high or low protein intake according to overall median levels. Hierarchical multiple linear regression was fitted to estimate the effect of protein intake per kg during pregnancy on weight gain. Results Women presented an average weight gain of 12.8kg (SD=6.34) and 26.8kg/m2 (SD=4.78) of Body Mass Index. Those who consumed a diet with high levels of protein content significantly presented less weight at postpartum (p<0.01) lower Early-Pregnancy Body Mass Index (p<0.01). In the hierarchical linear regression, it was found a negative association of protein intake per kg and Weight gain (b=-4.3025; IC95%=-6.0215; -2.5836; p<0.01). In the final model, all others covariates (energy, schooling, family income and gestational age) were significantly associated with the outcome (p<0.05). The additional model showed a negatively association between Early-Pregnancy Body Mass Index and weight gain (b=-0.2951; IC95%= -0.4987; -0.0915; p<0.01). Conclusion Higher levels of protein intake per kg of body weight during pregnancy were associated with lower weight gain.

ABSTRACT Objective This study estimated the combined prevalence of insufficient number of hours of sleep per day and excess body adiposity among young students. The sociodemographic and behavioral characteristics associated with this concurrent health conditions were investigated. Methods This is a cross-sectional school-based study of 975 participants aged 11-14 years in Florianópolis, Santa Catarina state, Brazil. Body adiposity was assessed based on tricipital and subscapular skinfold measurements and classified according to Lohman. The total number of hours of sleep per day was reported by the students’ parents/guardians, and it was classified as follows: as <8 hours per day and ≥8 hours per day. Data on sociodemographic characteristics, food consumption, and physical activity were collected using a self-administered questionnaire. The chi-square test and multinomial logistic regression with a 5% significance level were used to evaluate the association between the variables. Results The combined prevalence of insufficient number of hours of sleep per day and excess body adiposity was 25.1% (CI95%:20.7-29.9). The sociodemographic and behavioral factors predictive of these conditions were as follows: 13-14 year age group and household monthly income in the intermediate tertile. Conclusion The concurrent presence of insufficient sleep and excess body adiposity was found in a little more than a quarter of the students investigated. The population subgroups belonging to the 13-14 year age group and intermediate tertile of income were more likely to have concurrent insufficient number of hours of sleep per day and excess body adiposity.

The volitional nature of motivation and cultural creativity: an anthropological investigation
Authors: Migueles Carmen Pires , Zanini Marco Tulio Fundão
Published: October 2018

Abstract: We examine the volitional, non-rational nature of motivation and its impact on symbolic production at work. Based on a ethnographic study on a Brazilian special police force we argue that institutional stability and stable symbolic frames of references have long been taken for granted in studies of motivation, thus leaving aside the role of aesthetical demand in producing active symbolic elaboration at work. Unstable institutional frames of reference are relevant to understand the efforts of internal integration, identity building and relations of alterity at work. In this sense, this article has the main objective of contributing to the studies on intrinsic motivation within organizations.

ABSTRACT Reverse osmosis is the technology commonly used to produce fresh water from brackish groundwater. Due to the reject brine generated in desalination plants by reverse osmosis, vulnerability assessment to define critical areas to monitor waters from desalination has been an important tool for delineating the monitoring networks required for surveillance of potential salinization sites. The objective of this study was to assess the quality of waters sampled in desalination plants by a quality index, which provides a relative assessment of water vulnerability to potential salinization. The present study proposes an index to assess the quality of waters from desalination plants initially using the chemical parameters electrical conductivity, sodium adsorption ratio, Mg2+/Ca2+ ratio, and the ions sodium, chloride and bicarbonate. The index to assess quality of waters from desalination plants showed good performance and can include additional parameters referring to the soil and crop exploited. High values of the relative index of quality of waters from desalination plants are considered as possible indicators of risk of soil salinization and groundwater contamination. The highest level of land use impact on the quality of waters from desalination plants was found in reject brine samples followed by well water samples.

ABSTRACT Soil salinity directly affects plants, interfering in the emission of fluorescence, and promoting the degradation of photosynthetic pigments. Thus, estimating the damage to the photosynthetic apparatus caused by saline water is an important tool to detect abiotic stresses. For this purpose, sorghum plants were cultivated in a greenhouse and irrigated with two water sources (NaCl and salt mixture) with six levels of electrical conductivity (EC) (0, 2.5, 5, 7.5, 10, and 12.5 dS m-1), forming a 6 × 2 factorial in randomized blocks with four repetitions. At 60 days after sowing, the photosynthetic pigments were quantified, the chlorophyll a fluorescence parameters (initial fluorescence [F0]; variable fluorescence [Fv]; maximum fluorescence [Fm]; quantum efficiency of photosystem II - PSII [Fv/Fm]; electron flux per reaction center [ET0/CR]; quantum energy dissipation [DI0/CR] and quantum yield for heat dissipation [φD0]) were evaluated. The photosynthetic pigments were decreased with an increase in the salinity of the irrigation water, and were more expressive at higher electrical conductivities. With the wear on the photosynthetic apparatus by the increase in salinity, a reduction in the emission of the chlorophyll a fluorescence was observed, pointing to a possible photoinhibition of photosystem II.

ABSTRACT This study aimed to evaluate NPK formulations used in fertilization at sowing associated with and without humic substances (HS) in terms of the agronomic characteristics and grain quality for malt from the barley cultivars BRS Brau and BRS Elis, focusing on the agricultural years 2015 and 2016 in Guarapuava, PR. The experimental design was a randomized block, in a factorial 5 x 2 format, with five fertilizations: 0 kg ha-1 (control); 100 kg ha-1 of NPK; 100 kg ha-1 NPK + HS; 250 kg ha-1 of NPK; and 250 kg ha-1 NPK + HS, using two barley cultivars, BRS Brau and BRS Elis, replicated four times. The variables evaluated were hectoliter weight, grain yield, malt quality by means of sort 1, 2 and 3, and the protein percentage. The data evaluated were submitted to joint variance analyses for the agricultural crops, and the means were compared through non-orthogonal contrasts. The use of humic substances in NPK formulations provides an increase in grain yield, and its effect is observable in the lower doses of NPK + HS formulations. The lower dose of NPK formulation combined with the humic substance reduced class 1 and increased class 3 in agricultural crops from the years 2015 and 2016. The 2016 crop, with favorable climatic conditions, presented improved hectoliter mass, grain yield and quality of the barley grains, based on commercial grade.

Published: October 2018

ABSTRACT The objective of this study was to evaluate the models proposed by manufacturers and in the literature with respect to soil moisture measurement and to evaluate the performance of the CS616 sensor in the calibration of disturbed and undisturbed soil samples. These calibrations were performed using linear and quadratic models. Disturbed samples were collected in São Gabriel/BA, six samples placed in pots, whereas undisturbed samples were collected in Cruz das Almas/BA, three samples directly collected in the area and placed in a container. A calibration was performed between 21/12/2016 and 08/01/2017. The models proposed in the literature and by manufacturers differed in the estimation of volumetric soil moisture. Disturbed soil samples had higher data dispersion than undisturbed samples, due to factors such as grain size and bulk density, which influence the calibration data. The CS616 sensor had satisfactory performance in the calibration of disturbed and undisturbed samples, with excellent fit of the soil moisture data. Using soil moisture contents obtained by the CS616 sensor, without a previous calibration, may lead to errors in the results, confirming the need for a specific calibration for each type of soil.

ABSTRACT Reconstituted wood panels are widely used in various branches of the wood industry, such as in the furniture sectors and various segments of urban and rural construction. In Brazil, agricultural and forestry residues are abundantly generated, making feasible the study, development and application of alternative and sustainable materials, produced from the use of these wastes. The aim of this study was to produce high-density homogenous panels with wood residues of Pinus elliottii and oat hulls (Avena sativa), pressed with two types of adhesive, castor oil-based polyurethane and melamine formaldehyde, and to evaluate the physical performance of these panels. The physical performance of the panels was evaluated based on the ABNT NBR 14810: 2006, ANSI A208.1: 1999 and BS EN 312: 2003 standards. Analysis of variance (ANOVA) was performed to test the influence of the factors percentage of oat hull, percentage of adhesive and type of adhesive, and the interactions between these factors on the physical properties of the panels. The results indicated physical properties, in some treatments superior to the requirements stipulated by the consulted standards. It was concluded that the panels produced with the castor oil-based polyurethane adhesive showed better physical performance when compared with the panels produced with the melamine formaldehyde adhesive.

ABSTRACT Several types of seeds have been initially used in the food industry due to the great potential that vegetable proteins have. Baru is a fruit commonly found in the Cerrado biome, having a high nutritional value. This paper aimed to determine and analyze the drying kinetics of whole and defatted baru almond flours at different temperatures. The flour resulting from almond milling was defatted using petroleum ether. The drying processes were performed at temperatures of 40, 50 and 60 ºC. The mathematical models of Page, Henderson and Pabis, Midilli & Kucuk, Thompson and Approximation of Diffusion were fitted to the experimental data. The results showed a noticeable effect of air temperature on the drying kinetics of whole and defatted baru almond flours. According to the statistical parameters of analysis, the models Midilli & Kucuk and Page were the ones with the best fits to the experimental data. The effective diffusivity values found ranged from 8.02 × 10–10 to 19.90 × 10–10 m2 s-1 and for the activation energy were 22.39 and 39.37 KJ mol-1 for whole and defatted almonds, respectively.
SEROPREVALENCE OF Chlamydia psittaci IN CAPTIVE MACAWS (Ara spp.) IN THE DEPARTMENT OF LIMA, PERU
Authors: Carlos Nancy , Luyo Elizabeth Portuguez
Published: October 2018

Abstract The presence of Chlamydia psittaci in captive psittacines may have a subclinical presentation, despite its importance in immunosuppressed birds and humans because of its zoonotic potential. The aim of this study was to determine the seroprevalence of C. psittaci in macaws (Ara spp.). Birds were kept in captivity in three zoos in the department of Lima. In total, 34 adult birds (11 Ara macao, 15 Ara ararauna, 5 Ara chloropterus, and 7 Ara severus) were studied. A total of 0.5 mL of blood was obtained from the right jugular vein and placed into a coagulant-free tube. Blood serum was analyzed using an ELISA (Immunocomb Avian Chlamidopophila psittaci kit) in order to determine IgG antibody titers. The presence of antibodies to C. psittaci in macaws are reported for the first time in Peru, with a seroprevalence of 44.74 ± 15.84% (17/38). No significant differences between the origin of birds and the presence of the antibodies were found.
Uma lembrança a Black Narcissus – construindo alteridade e desconstruindo erotismo
Authors: Venchi Mariane
Published: October 2018

Resumo Esta é uma reflexão sobre as estratégias discursivas que o filme britânico Black Narcissus(1946) utiliza quando lida com signos eróticos e raciais ao confrontar as culturas cristã e indiana no espaço colonialista na Era do Hollywood Production Code [“Código de Produção de Hollywood”]. Propomos um diálogo entre as premissas de Georges Bataille, Octavio Paz e Michel Foucault ao dissecarem o tema da sexualidade humana e seus mecanismos de repressão por diferentes perspectivas, enfatizando também a necessidade de expandirmos a temática do erotismo para além do par binário proibição/transgressão em sociedades não ocidentais e suas sutis gradações entre o sagrado e o profano.

Published: October 2018

Abstract Objective: this integrative literature review aimed to systematize scientific production regarding the process of aging, mental health, and suicide. Method: the LILACS, MEDLINE, and PubMed databases were used to search for papers published between 2007 and 2017. The final analysis included 34 papers. Result: descriptive North American studies in English were most prevalent. The largest number of papers on the theme was published in 2013. The researchers used questionnaires and interviews as instruments for questions involving aging and suicidal ideation. The papers revealed an association of suicide or suicidal ideation in elderly persons who manifested anxiety, depressive symptoms, depression, physical diseases, low educational and socioeconomic levels, and chronic diseases. Conclusion: this integrative review reinforces the need for investment in public policies and spaces that offer receptiveness, listening, and safety for the aged population, as well as surveys with more robust methodologies to investigate the phenomenon under analysis.

Por um cuidado respeitoso
Authors: Armendane Geraldo das Dôres de
Published: October 2018

Resumo Os médicos deparam, cotidianamente, com conflitos e dilemas morais dos quais muitas vezes não conseguem dar conta. Diante disso, este artigo apresenta a proposta de uma bioética filosófica especial, a partir das contribuições de Darlei Dall’Agnol para o debate filosófico em bioética, com base no cuidado respeitoso, e a importância desse novo conceito para o relacionamento entre médico e paciente, segundo a concepção metaética de cognitivismo moral de inspiração wittgensteiniana. Vale considerar, porém, que as quatro regras práticas da medicina (veracidade, privacidade, confidencialidade e fidelidade) não conseguem lidar com conflitos e dilemas morais que os médicos enfrentam no exercício da profissão. Por isso, consideramos imprescindível a esses profissionais formação moral baseada na sabedoria prática, que integre o princípio do cuidado e o princípio do respeito em um único conceito, o “cuidado respeitoso”, como atitude humana fundamental para o relacionamento salutar entre médicos e pacientes.

Published: October 2018

Resumo A violência, em suas diversas formas e manifestações, não pode ser vista pelos profissionais de saúde como questão alheia a seu trabalho. Este estudo teve como objetivo analisar a responsabilidade desses profissionais na notificação dos casos de violência. A busca foi realizada na Biblioteca Virtual em Saúde, considerando o período entre 2008 e 2013. Da análise surgiram três eixos temáticos: “legislação brasileira”; “responsabilidade dos profissionais de saúde no processo de notificação” e “códigos de ética dos profissionais de saúde”. Conclui-se que a maioria dos artigos relativos aos códigos de ética aponta a necessidade de denunciar os casos de violência aos respectivos conselhos, autoridades e órgãos competentes. Porém, nota-se que não explicitam a obrigatoriedade da notificação em casos de violência. Assim, torna-se necessário revisar cada um dos códigos deontológicos da área da saúde, considerando a importância de referirem-se especificamente à violência.

Published: October 2018

Resumo Visando dar mais autonomia a pacientes terminais, foi criada pelo Conselho Federal de Medicina a Resolução 1.995/2012, que dispõe sobre o testamento vital. Para avaliar o conhecimento dos estudantes de medicina do primeiro ao sexto ano em relação a conceitos e condutas éticas diante de pacientes terminais, foi realizado este estudo transversal, mediante aplicação de questionário a 348 alunos. Destes, 251 (72,1%) identificaram corretamente questões relacionadas a condutas na terminalidade, mas apenas 23,5% demonstraram conhecer o conceito de testamento vital. Apesar do baixo índice, 80,1% afirmaram ter a intenção de respeitá-lo, no caso de pacientes terminais. Pesquisas sobre o assunto são importantes para alertar sobre lacunas nos currículos desses futuros médicos. Além disso, o caráter reflexivo desse tipo de estudo permite trabalhar questões éticas fundamentais para o atendimento humanizado.
Interfaces, lacunas e desafios entre bioética e oncologia
Authors: Lima Camila Vasconcelos Carnaúba , Biasoli Luis Fernando
Published: October 2018

Resumo Bioética e oncologia são áreas interdisciplinares que visam o entendimento integral do ser humano. Este artigo levantou estudos sobre temas de interface nessas áreas, identificando possíveis contribuições, lacunas e desafios emergentes. Foi feita revisão integrativa que buscou os descritores “oncologia” ( oncology ) ou “câncer” ( cancer ); “bioética” ( bioethics ) ou “ética” ( ethics ) e encontrou 29 artigos. As discussões remetiam ao conhecimento ou aplicação de princípios da bioética na oncologia; dificuldades na comunicação médico-paciente; e aspectos e normas éticas em pesquisa. Torna-se necessário, portanto, garantir a aplicação de princípios bioéticos, ampliar investimentos no ensino formal de bioética, nas habilidades interpessoais e de comunicação médico-paciente, e divulgar a bioética para a população em geral. Espera-se que este estudo dê continuidade aos já realizados e que surjam novos interesses sobre o assunto.

Abstract Introduction: Delayed graft function (DGF) is a frequent complication after deceased donor kidney transplantation with an impact on the prognosis of the transplant. Despite this, long-term impact of DGF on graft function after deceased donor kidney transplantation has not been properly evaluated. Objective: The main objective of this study was to evaluate risk factors for DGF and the impact of its occurrence and length on graft survival and function. Methods: A retrospective cohort study was performed in 517 kidney transplant recipients who received a deceased donor organ between January 2008 and December 2013. Results: The incidence of DGF was 69.3% and it was independently associated with donor's final serum creatinine and age, cold ischemia time, use of antibody induction therapy and recipient's diabetes mellitus. The occurrence of DGF was also associated with a higher incidence of Banff ≥ 1A grade acute rejection (P = 0.017), lower graft function up to six years after transplantation and lower death-censored graft survival at 1 and 5 years (P < 0.05). DGF period longer than 14 days was associated with higher incidence of death-censored graft loss (P = 0.038) and poorer graft function (P < 0.001). No differences were found in patient survival. Conclusions: The occurrence of DGF has a long-lasting detrimental impact on graft function and survival and this impact is even more pronounced when DGF lasts longer than two weeks.

Authors: Rédua Renato Barcellos , Rédua Paulo César Barbosa
Published: October 2018

ABSTRACT Hypodontia is the most prevalent craniofacial malformation in mankind. It may present a wide variety of manifestations and, depending on the number and location of missing teeth, it may affect the esthetics, mastication, speech and occlusal balance. This paper discusses the therapeutic approaches to solve this condition, describing a case report with hypodontia of one mandibular lateral incisor, which treatment option included space closure at the region of hypodontia associated with composite resin restorations in the mandibular central incisors. The three-year follow-up after treatment revealed occlusal stability, adequate intercuspation in Class I relationship and excellent micro and macroesthetics.
Dos alienígenas à jurualogia: reflexões de um provável xamã guarani-mbya
Authors: Huyer Bruno
Published: October 2018

Resumo Considerando as reflexões de um jovem guarani que tem como possível destino tornar-se um karai (xamã), a aposta deste texto é etnográfica. Conduzidos por um amigo e interlocutor que acompanho por aproximadamente nove anos, somos levados a diversas especulações sobre o universo e seus habitantes. Aliando sua disposição mitopoiética através de verdadeiras exegeses filosóficas e sua busca por entender corporalmente quem são os brancos através do que chamou de jurualogia, Vera’i passou a demonstrar cada vez mais sua inclinação ao xamanismo mbya. Motivada por seus familiares desde sua infância, tal inclinação passa a efetuar-se na medida em que pessoas começam a procurá-lo em busca de cura e tratamento para suas doenças.
