Authors: Amin Nirav H. , Hussain Waqas , Ryan John , Morrison Shannon , Miniaci Anthony , Jones Morgan H.
Published: April 2017

Background:

In 2002, Moseley et al published a randomized controlled trial (RCT) that showed no difference between knee arthroscopy and placebo for patients with osteoarthritis (OA). We wanted to assess the impact of the trial on clinical practice in the United States.

Purpose/Hypothesis:

To evaluate changes in knee arthroscopy practice before and after publication of the article by Moseley et al and to assess the effect of this landmark RCT on the behavior of practicing orthopaedic surgeons. We hypothesized that after publication of the Moseley trial, the overall frequency of knee arthroscopy would decrease, that the mean age of patients undergoing knee arthroscopy would decrease, and that the proportion of arthroscopies for a diagnosis of OA would decrease.

Study Design:

Descriptive epidemiology study.

Methods:

The State Ambulatory Surgery Database was used to analyze cases from 1998 to 2006, which were classified as meniscus tear, OA, or OA with meniscus tear. Changes in age, surgery rates, and case classification were evaluated before and after Moseley’s trial using Student t tests and analysis of variance.

Results:

After publication of the trial, the number of knee arthroscopies per year increased from 155,057 in 1998 to 172,317 in 2006 ( P ≤ .001). Mean patient age increased from 47.6 to 49.2 years ( P < .001). Meniscus tears increased from 69.1% to 70.8%, representing approximately 15,500 additional cases per year. OA decreased from 10.6% to 7.2%, representing approximately 4000 fewer cases per year. OA with meniscus tear increased from 20.3% to 22.0%, representing approximately 6400 additional cases per year.

Conclusion:

While overall age and rates of knee arthroscopy increased contrary to our hypothesis, we identified a decrease in rates of knee arthroscopy for OA after publication of the Moseley trial, demonstrating that well-publicized RCTs can influence patterns of clinical practice.

Authors: Mygind-Klavsen Bjarne , Nielsen Torsten Grønbech , Lind Martin Carøe
Published: April 2017

Background:

Posterior cruciate ligament (PCL) reconstructions are rarely performed compared with that for the anterior cruciate ligament (ACL).

Purpose:

To evaluate the clinical and functional outcome after isolated or multiligament PCL reconstruction.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Patients who underwent PCL reconstruction between 2002 and 2010 were included. Standardized follow-up was performed between 2012 and 2013 and consisted of subjective scores (Tegner activity score, Knee injury and Osteoarthritis Outcome Score [KOOS], and subjective International Knee Documentation Committee [IKDC] score) and objective measures, including knee laxity (KT-1000), extension strength, and overall IKDC score.

Results:

One hundred ninety-six patients were identified, of which 172 were available for postoperative follow-up: 39.3% with isolated PCL and 60.7% with multiligament injury. One hundred ten patients were available to complete both clinical follow-up and subjective questionnaires; 62 patients returned the subjective questionnaires. Mean follow-up was 5.9 years (range, 3.1-9.7 years). KOOS scores at follow-up in the isolated PCL group by subscale were 74 (symptoms), 76 (pain), 80 (activities of daily living), 55 (sport), and 55 (quality of life). Scores for patients in the multiligament group were 73 (symptoms), 79 (pain), 82 (activities of daily living), 53 (sport), and 56 (quality of life). Tegner scores were 4.5 and 4.4, respectively, and subjective IKDC scores were 63.8 and 65.0. The mean side-to-side difference in knee laxity was 2.7 mm in the isolated PCL group compared with 2.8 mm in the multiligament group. At 1-year follow-up there were significant differences in KOOS outcome scores between the isolated PCL subgroup and the multiligament subgroup, but no differences at final follow-up. Twelve patients (5%) had PCL revision surgery within the follow-up period.

Conclusion:

Despite the type of injury, there were only minor differences in knee laxity and subjective outcome scores between the isolated PCL group and the multiligament group. The overall revision rate in this study was 5.2%.
Ore characterization and textural relationships among gold, selenides, platinum-group minerals and uraninite at the granite-related Buraco do Ouro gold mine, Cavalcante, Central Brazil
Authors: Menez J. , Botelho N. F.
Published: April 2017

Gold occurrences have been reported in the northeastern part of Goiás State since the beginning of the 18th Century. The main mineralization is associated with Paleoproterozoic peraluminous, syntectonic granites of the Aurumina Suite and associated metasedimentary,graphite-bearing country rocks of the Ticunzal Formation. In the Buraco do Ouro gold mine, the mineralization is hosted in muscovite-quartz mylonite in a silicified shear zone near the contact between biotite-muscovite granite and paragneiss of the Ticunzal Formation. The ore mineralogy consistsof gold, paraguanajuatite (Bi2Se3), kalungaite (PdAsSe), isomertieite [Pd11Sb2As2], mertieite II [Pd8(Sb,As)3], sperrylite (PtAs2), padmaite (PdBiSe), bohdanowiczite (AgBiSe2), clausthalite (PbSe),krutaite (CuSe2), ferroselite (FeSe2), uraninite (UO2) and unnamed Ag-Pb-Bi-Se minerals. Local magnetite concentrations and rare chalcopyrite and pyrite are also associated with both mineralized and barren mylonites in a gangue consisting of muscovite, quartzand rare tourmaline. High TiO2 muscovite clasts in the ore are interpreted as the magmatic muscovite of the original granite, and the mineralization is considered to be synchronous with the syntectonic granite intrusion during syn-emplacement shearing and alteration. The associationbetween granitic rocks and platinum-group element (PGE)-bearing gold mineralization observed in the Buraco do Ouro mine is uncommon and unique in the context of the Aurumina Suite and the Ticunzal Formation, where gold deposits and occurrences are gold-only. The chemical data suggest the possibilityof a solid solution between paraguanajuatite and bohdanowiczite. In addition, a complex intergrowth occurs between paraguanajuatite, clausthalite and Ag-Pb-Bi-Se phases, one of which, a Pb-Bi-Se phase could represent a new mineral. Uraninite is identified for the first time in this mineralassemblage and its concentration in the ore seems important, as revealed by high gamma spectrometric measurements in the samples collected in the mine. The association between gold and uranium constitutes a regional signature, observed in both gold and uranium deposits in the Cavalcante region.
Nomenclature of the perovskite supergroup: A hierarchical system of classification based on crystal structure and composition
Authors: Mitchell Roger H. , Welch Mark D. , Chakhmouradian Anton R.
Published: April 2017

On the basis of extensive studies of synthetic perovskite-structured compounds it is possible to derive a hierarchy of hettotype structures which are derivatives of the arisotypic cubic perovskite structure (ABX3), exemplified by SrTiO3(tausonite) or KMgF3(parascandolaite) by: (1) tilting and distortion of theBX6octahedra; (2) ordering ofA- andB-site cations; (3) formation ofA-,B- orX-site vacancies. This hierarchical scheme can be applied to some naturally-occurring oxides, fluorides,hydroxides, chlorides, arsenides, intermetallic compounds and silicates which adopt such derivative crystal structures. Application of this hierarchical scheme to naturally-occurring minerals results in the recognition of a perovskite supergroup which is divided into stoichiometric and non-stoichiometricperovskite groups, with both groups further divided into singleABX3or doubleA2BB'X6perovskites. Subgroups, and potential subgroups, of stoichiometric perovskites include: (1) silicate single perovskites of the bridgmanite subgroup;(2) oxide single perovskites of the perovskite subgroup (tausonite, perovskite, loparite, lueshite, isolueshite, lakargiite, megawite); (3) oxide single perovskites of the macedonite subgroup which exhibit second order Jahn-Teller distortions (macedonite, barioperovskite); (4) fluoride singleperovskites of the neighborite subgroup (neighborite, parascandolaite); (5) chloride single perovskites of the chlorocalcite subgroup; (6)B-site cation ordered double fluoride perovskites of the cryolite subgroup (cryolite, elpasolite, simmonsite); (7)B-site cation orderedoxide double perovskites of the vapnikite subgroup [vapnikite, (?) latrappite]. Non-stoichiometric perovskites include: (1)A-site vacant double hydroxides, or hydroxide perovskites, belonging to the söhngeite, schoenfliesite and stottite subgroups; (2) Anion-deficient perovskitesof the brownmillerite subgroup (srebrodolskite, shulamitite); (3)A-site vacant quadruple perovskites (skutterudite subgroup); (4)B-site vacant single perovskites of the oskarssonite subgroup [oskarssonite]; (5)B-site vacant inverse single perovskites of the coheniteand auricupride subgroups; (6)B-site vacant double perovskites of the diaboleite subgroup; (7) anion-deficient partly-inverseB-site quadruple perovskites of the hematophanite subgroup.
Tautology Elimination, Cut Elimination, and S5
Authors: Indrzejczak Andrzej
Published: April 2017

Tautology elimination rule was successfully applied in automated deduction and recently considered in the framework of sequent calculi where it is provably equivalent to cut rule. In this paper we focus on the advantages of proving admissibility of tautology elimination rule instead of cut for sequent calculi. It seems that one may find simpler proofs of admissibility for tautology elimination than for cut admissibility. Moreover, one may prove its admissibility for some calculi where constructive proofs of cut admissibility fail. As an illustration we present a cut-free sequent calculus for S5 based on tableau system of Fitting and prove admissibility of tautology elimination rule for it.
Synthesis, structural characterization and DNA studies of trivalent cobalt complexes of (2E)-4N-substituted-2-[4-(propan-2-yl)benzylidene]hydrazinecarbothioamide
Authors: Panchangam Murali Krishna , K Hussain Reddy
Published: April 2017

This paper describes trivalent cobalt complexes of hydrazinecarbothioamides derived from 4-(propan-2-yl) benzaldehyde and substituted thiosemicarbazides NH2NHC(S)NHR, where R = H (1), Me (2), Et (3) or Ph (4) have been synthesized and characterized. The prepared ligands and complexes were characterized using various physicochemical techniques viz. elemental analysis, molar conductance, magnetic susceptibility measurements, IR, electronic absorption spectral studies and cyclic voltammetry. The electronic spectra in DMSO solvent and magnetic susceptibility data of complexes reveal that the complexes are diamagnetic with low spin octahedral cobalt(III) complexes. The absorption titration studies revealed that each of these complexes is an avid binder to calf thymus-DNA. The apparent binding constants are in the order of 107–108 M-1 . The nucleolytic cleavage activities of the ligands and their complexes were assayed on pUC18 plasmid DNA using gel electrophoresis in the presence and absence of H2O2. The ligands showed increased nuclease activity when administered as cobalt complexes. All the complexes behave as efficient chemical nucleases with hydrogen peroxide activation. These studies revealed that the complexes exhibit both oxidative and hydrolytic chemistry in DNA cleavage.

Published: April 2017

Six esters have been synthesized in the acetylation, benzoylation and Baeyer-Villiger oxidation of starting materials totaradiol 1, totaratriol 2, hinikione 7 and totarolone 8. A complete theoretical study of the reaction has been carried out including highly regioselectivity induction experiments and using density functional methods B3LYP/6-31G(d). The analysis of the nucleophilic Parr functions P - k and the electrostatic potential in diterpenes 1 and 2 offered an explanation of the regioselectivity found in these reactions and in Baeyer-Villiger reaction we use transition state theory and the electrostatic potential to understand the high regioselectevity observed, we found that the regioselectivity is kinetically and thermodynamically favorable and the electronic density is located in the multi-substituted carbon.
Exploring the factors affecting learners’ continuance intention of MOOCs for online collaborative learning: An extended ECM perspective
Authors: Zhou Junjie
Published: April 2017

The purpose of this paper was to investigate what factors influence learners’ continuance intention in massive open online courses (MOOCs) for online collaborative learning. An extended expectation confirmation model (ECM) was adopted as the theoretical foundation. A total of 435 valid samples were collected in mainland China and structural equation model (SEM) approach was adopted. The descriptive statistics show that platforms from abroad, such as Coursera and Khan, are more popular than native ones in mainland China. The empirical results show that the effects of three ECM factors (satisfaction with prior learning experience, confirmation with prior learning experience, and perceived usefulness) are significant. Different factors have different predicting power. Knowledge outcome is the first powerful indicator of learners’ continuance intention of MOOCs, followed by social influence, learners’ satisfaction with prior learning experience, and performance proficiency. The effects of knowledge outcome, performance proficiency, and social influence are significant, showing the success of extended ECM.

Published: April 2017

In freshwater ecosystems, water temperature plays as an environmental factor that regulates its structure and function. A research on the impacts of changes in temperature to the dynamics of the Phytoplankton community structure has been done. Data from nineteen-year period (1995 to 2013) were collected from Cirata Reservoir as an example of artificial tropical lake in Indonesia. The research aimed to determine the changes of water temperature as the impact of climate warming on the dynamics of phytoplankton community structure. Different measures such as species richness, diversity index, and abundance were measured in order to understand the changes of phytoplankton community structure. Trend analysis, linear regression, and correlation were applied to achieve our objective. The study revealed that changes in water temperature have affected the species richness, but not the diversity index and abundance of the phytoplankton. Bacilariophyceae and Cyanophyceae were found as two predominant phytoplankton classes in the lake with percentage of 48,45 and 41,43 respectively, assuming their capacity to adapt the new environment. This study suggests that climate warming implies changes of the freshwater ecosystems.

Published: April 2017

ABSTRACT Objective: investigate the understanding of nurses on nurse prescribing conformity to the care needs of hospitalized patients and factors associated with that conformity. Method: a descriptive study, with a quantitative approach, was conducted at 20 in-patient units of a teaching hospital in the state of São Paulo. The participants (N=139) answered a semi-structured questionnaire. Results: For 43 (30.9%) nurses, nurse prescribing is always in line with patients' care needs. The fields of body care and elimination, skin and mucosa care and investigation and monitoring were the most frequently addressed. Conclusion: in the perception of most nurses, nurse prescribing does not conform with patients' health heeds. The establishment of strategies to improve prescribing quality is recommended, as well as the development of permanent qualification programs and the systematic use of instruments for assessment of patients' care demands regarding nursing.

Published: April 2017

Este estudo tem como objetivo fazer um levantamento do ensino de oftalmología que é oferecido aos alunos de graduação em enfermagem. Para sua efetivação foi enviado um questionário a todos os cursos de enfermagem do Brasil, no qual são abordadas questões relativas ao ensino que é administrado. Do total correspondente a 87 questionários foram obtidas 76 respostas (87,36%), restando assim, 11 (12,64%) correspondências sem terem sido respondidas. Os nossos achados apontam para um quadro, no qual verifica-se que 55,26% das escolas incluem em seus currículos assuntos de oftalmología, sendo que em apenas 14,28% destas escolas são abordados aspectos ligados à prevenção da cegueira. Considerando que na literatura nacional e estrangeira pesquisadas não foi evidenciado qualquer relato sobre o preparo do enfermeiro em oftalmología preventiva e analisando os dados obtidos no presente estudo, esperamos que os docentes em enfermagem reflitam sobre a importância deste ensino na formação do enfermeiro como educador e agente de saúde na comunidade.

Published: April 2017

RESUMO: Este artigo discute questões sobre diversidade linguístico-cultural e educação do campo junto ao Povo Tradicional Pomerano, conforme o Decreto nº 6.040 de 2007. Questiona a educação homogeneizadora promovida para o campo, que, segundo Paulo Freire e Alfredo Bosi, despreza culturas e línguas do povo. Analisa dados produzidos em grupos de pesquisa, com discussões acumuladas, registros nos diários de campo e arquivos de fotos. Executa uma revisão crítica da produção teórico-científica sobre o tema com leitura interpretativa. Avalia dificuldades históricas experimentadas por esse povo tradicional no Estado do Espírito Santo no processo de escolarização. Inscreve-se no debate sobre ações afirmativas que promovem, atualmente, avanços nos aspectos legais e conceituais para a formação dos sujeitos em contextos rurais. As análises permitem identificar aumento de pesquisa acadêmica e maior interesse em encontrar propostas alternativas para superar problemas históricos, como a invisibilidade do conhecimento, da língua e da cultura do Povo Tradicional Pomerano.
Transexualidade, psicose e feminilidade originária: entre psicanálise e teoria feminista
Authors: Lattanzio Felippe Figueiredo , Ribeiro Paulo de Carvalho
Published: April 2017

Resumo O presente estudo procura analisar as teorizações sobre a transexualidade, com o objetivo de problematizar sua inclusão no campo das psicoses. Várias concepções sobre a transexualidade, que se estendem desde o DSM até as teorizações recentes de psicanalistas da vertente lacaniana, são analisadas de maneira crítica através de um diálogo com autoras da teoria feminista. A hipótese defendida é a de que o destino dado à feminilidade originária é diferente na transexualidade e em alguns casos de psicose, conduzindo assim à conclusão de que a transexualidade não pode ser classificada a priori como uma patologia.
Da perda do objeto: o encontro sobre o abismo
Authors: Alves Rafaela Brandão , Almeida Marcela Toledo França de
Published: April 2017

Resumo Este artigo teoriza sobre a relação entre a perda do objeto de satisfação plena e as possíveis experiências de gozo. A fim de empreender essa discussão serão tomados como centrais os conceitos de das Ding em Freud e objeto a em Lacan, alicerçados nos conceitos de angústia, gozo e erotismo, este último encontrado nas elaborações do filósofo Georges Bataille. Ademais, será resgatada a noção de sublimação, via de satisfação pela qual o sujeito bordeja o furo deixado pela perda do objeto fazendo um laço social. O registro simbólico é, portanto, o responsável por fazer este laço, já que estaria nas palavras a possibilidade de um encontro sobre o abismo cavado pela divisão sexual. A linguagem teria, portanto, a função de preencher o buraco deixado pela perda do objeto, uma promessa apaziguadora, mas impossível de ser bem-sucedida, uma vez que sobre essa fenda nada se fala.
Arte e loucura como limiar para outra história
Authors: Franceschini Erica , Fonseca Tania Mara Galli
Published: April 2017

Resumo Pretendemos problematizar arte e loucura, inicialmente discutindo a experiência do pesquisador em relação às imagens do mundo, com o testemunho e a figura do louco e, consequentemente, com o fora que ela evoca. Em seguida nos colocamos diante do muro, situação-limite na qual a loucura enquanto catástrofe e a arte enquanto via poética vêm compor um limiar, ausência que Blanchot transpõe à linguagem para dar a ver outras constelações possíveis, tanto de palavras quanto de seus inomináveis. Por fim, com Walter Benjamin, pomos a história da loucura a contrapelo, e, mergulhados no Ateliê de Escrita do Hospital Psiquiátrico São Pedro, desvelamos que a arte pode, na relação com a loucura, tornar-se a linguagem essencial na perigosa travessia em direção à experiência, transpondo a vivência desse estado assustador para trazer ao mundo outro sentido, reconhecendo outros modos de existência que podem vir a ser outras poéticas de vida.

ABSTRACT: European apple canker (EC) is caused by Neonectria ditissima, a pathogen officially registered as a quarantine pest in 2012. Thirty-five isolates of N. ditissima of different geographical regions of southern Brazil from apple branches showing symptoms of EC were identified by the specific pair primers Ch1 and Ch2 and analyzed concerning the virulence on Gala apple cultivar and morphophysiological characteristics. The disease symptoms were characterized and the isolates compared based on average mycelium growth (AMG), mycelium growth index (MGI), colony color, conidia type, dimensions and growth on potato dextrose agar (PDA), malt agar (AM), and synthetic SNAY (SN) culture media. Nineteen isolates showed the greatest AMG on PDA, forming three growth groups of 35.56 (GI), 52.71 (GII), and 62.67mm (GIII). Seven isolates showed MGI greater than 4.0mm diameter on PDA compared with that on AM and SN. The highest conidia production was on SN, and the predominant colony color in all media was white to beige with central pigmentation of brown and borders colored in shades of beige. There were significant differences among the average dimensions of micro- and macroconidia on PDA, AM, and SN. The pathogenicity was confirmed for all isolates despite of different morphophysiological characteristics. There was no correlation among isolates morphophysiological variability, virulence, and geographical origin.

ABSTRACT: Pyometra is a common disease in intact female dogs and can cause glomerulopathy and tubular injury. This study aimed to evaluate kidney injury in female dogs with pyometra, as well as progression of the injury during treatment and the markers of this condition. This study analyzed 20 intact female dogs with both clinical and sonographic diagnosis of pyometra. Dogs were treated with intravenous fluids and antibiotics, and an ovariohysterectomy was performed. The following parameters were assessed at eight separate time points: blood pressure; serum creatinine, phosphorus, and urea levels; urinalysis and urinary biochemical parameters [urinary gamma-glutamyl transferase (uGGT) and urinary protein-to-creatinine ratio (UPCR)]; glomerular filtration rate (GFR); and urine output. All dogs showed some degree of kidney injury at the time of pyometra diagnosis. This was transient in most animals, resolving with treatment of the pyometra. Measurement of uGGT and UPCR identified renal parenchymal injury, helping to determine the prognosis of the animals analyzed in the present study.

Published: April 2017

ABSTRACT: The cultivation and processing of sweet potatoes into a variety of products yields both solid and liquid organic waste. Solid waste includes peelings and trimmings from the sweet potato root and sweet potato leaves and vines. Liquid waste results from various processing methods and creates significant amounts of nutrient rich waste water. Sweet potato waste materials contain carbohydrates, proteins, phenolic compounds, macro and micro nutrients, and pigments that have the potential of being extracted or utilized for various downstream processes and products. This review examines many of the different ways that these waste products can be utilized.

Published: April 2017

ABSTRACT: Herbicides used in the Clearfield® rice (Oryza sativa L.) production system have a potential for leaching. This can result in contamination of underground water resources and cause injury to not tolerant crops that are sown in a succession and/or crop rotation. The objective of this study was to determine the leaching potential and the residual activity of the herbicides used in the Clearfield® rice system. The experiment was conducted over a period of two years and consisted of conducting a field test to be followed by two bioassays with a year of difference between their implementation. Initially an experiment was conducted in lowland area where it was planted the cultivar of rice ‘PUITA INTA CL’. Approximately one and two years thereafter, soil samples from each plot were collected at intervals of 5cm to a depth of 30cm (B factor) for the bioassay to evaluate persistence of herbicides. Factor A was composed of mixtures formulated of imazethapyr + imazapic (75 + 25g a.i. L-1), imazapyr + imazapic (525 + 175g a.i. kg-1) in two doses, imazethapyr (100g a.i. L-1) and treatment control without application. Basing on results, it was concluded that the mixtures imazethapyr + imazapic, imazapyr + imazapic and imazethapyr leached into the soil, reaching depths of up to 25cm in lowland soil. Imidazolinone herbicides used today in the irrigated rice Clearfield® system are persistent in soil, and their phytotoxic activity can be observed up to two years after application.

Published: April 2017

ABSTRACT: Lecanicillium fungicola, which causes Dry bubble disease, induces infections and inflicts major losses in champignon production. The control can be managed through measures of hygiene and use of fungicides; however, in Brazil there are no registered products. This study aimed to estimate the influence of various essential oils extracted from Melissa officinalis, Thymus vulgaris, Origanum vulgare, Eucalyptus globulus, Cinnamomum zeylanicum and Syzygium aromaticum on the in vitro development and their uses. Therefore, analysis was performed of the L. fungicola isolates in vitro and the best oils were tested in vivo. Besides, the Agaricus bisporus - L. fungicola interaction was confirmed by scanning electron microscopy (SEM). Cinnamon and clove oils in concentrations of 0.4% and thyme oil of 0.8% were identified as good growth inhibitors of the pathogenic mycelium. Effective inhibition of the conidial germination was seen in all concentrations by cinnamon oil, and by clove and thyme oils only at 0.4% and 0.8%, respectively. When the essential oils were applied post-infestation in the in vivo experiments the incidence of the disease in the mushrooms was much lower. From the SEM it was clear that 19 hours after the inoculation of A. bisporus with L. fungicola, the spores had already completely germinated, revealing the presence of the infection. Therefore, the findings of this study indicated that the oil extracts of cinnamon, clove and thyme are potential and efficient alternatives in the control of dry bubble disease.

Resumo Objetivou-se avaliar o efeito do componente genético na expressão fenotípica de características produtivas de bovinos da raça Nelore submetidos à prova de desempenho individual. Os dados utilizados foram provenientes de 51 touros jovens participantes da Prova de Desempenho Individual de Touros Nelore realizada na fazenda experimental Capim Branco da Universidade Federal de Uberlândia. As características avaliadas foram peso e perímetro escrotal padronizado aos 365 e aos 450 dias de idade, área de olho de lombo e acabamento de carcaça. Com o intuito de avaliar a contribuição do componente genético no desempenho produtivo dos animais foram consideradas as predições das diferenças esperada na progênie dos animais e dos touros (pais dos animais). Para verificar os efeitos dos grupos genéticos sobre o desempenho produtivo foram realizadas análises de variância por meio do procedimento General Linear Model do aplicativo Statistical Analysis System. Verificou-se que os filhos de touros com maior potencial genético tendem a apresentar melhor desempenho produtivo. Concluiu-se que o uso de animais geneticamente superiores permite a obtenção de melhores índices zootécnicos refletindo em maiores ganhos em produtividade do rebanho.

Resumo Objetivos Avaliar o ganho de peso na idade adulta, bem como a influência sobre a prevalência da hipertensão. Métodos Estudo transversal, por meio de entrevista telefônica com indivíduos de 30-59 anos, recorte do Sistema Municipal de Monitoramento de Fatores de Risco para Doenças Crônicas Não Transmissíveis por Meio de Entrevistas Telefônicas (SIMTEL). Analisaram-se dados sociodemográficos, antropométricos e estilo de vida. O efeito independente do ganho de peso e do índice de massa corporal atual e aos 20 anos de idade na prevalência da hipertensão arterial foi analisado por meio de Regressão de Poisson. Resultados Mediana de 42 anos de idade (IC95%; 41,0-43,0). A média do ganho de peso relativo foi de 18,1 ± 11,1%. Na amostra, 7,0% tiveram ganho de peso nulo, 19,2% baixo, 34,2% médio e 39,4% alto. Na análise multivariada, o ganho de peso não se associou à hipertensão arterial, já o IMC atual teve associação significativa, sendo a prevalência 2,4 vezes maior nos obesos do que nos eutróficos, enquanto que nos obesos aos 20 anos de idade a prevalência de hipertensão foi 1,9 vezes maior. Conclusões Houve elevado ganho de peso na idade adulta, mas esse ganho não foi determinante para a hipertensão quando ajustado pelo IMC atual.

Resumo Introdução Objetivou-se analisar a qualidade do acolhimento no serviço de saúde bucal, considerando sua capacidade de resposta às necessidades do usuário. Metodologia Fizeram parte do estudo transversal, quantitativo, usuários da rede pública odontológica no âmbito da Atenção Primária à Saúde (APS) de três municípios de diferentes estados brasileiros (n = 1.312). A obtenção dos dados deu-se através de entrevista no interior das unidades de saúde. O estudo contemplou 15 variáveis referentes ao processo de acolhimento, as quais foram analisadas preliminarmente com testes qui-quadrado. As que apresentaram associação com a variável desfecho “capacidade de resposta às necessidades do usuário” foram analisadas, posteriormente, por meio da regressão logística e teste de seleção de atributos. Resultados Verificou-se que avaliação negativa do cumprimento das necessidades esteve estatisticamente associada ao atendimento do cirurgião-dentista e equipe; disponibilidade para dialogar sobre dúvidas, preocupações e problemas de saúde bucal; receptividade ao adentrar o serviço odontológico na APS; e recebimento de informações sobre condição de saúde bucal na APS. As demais variáveis não permaneceram associadas de forma significativa após o teste de seleção de atributos. Conclusão A qualidade do acolhimento dos serviços de saúde bucal está significativamente relacionada à humanização do atendimento, receptividade do cirurgião-dentista e equipe e aos processos de escuta e orientação.

Objetivo Intentamos establecer las hipótesis de trabajo del analista confrontado a la irrupción del cuerpo en la cura y que permiten elaborar transferencialmente la violencia pulsional. Procedimientos La experiencia clínica de los autores con un niño establece las bases teóricas que interrogan el rol del cuerpo. Este es luego analizado transferencialmente en tres situaciones clínicas. Conclusiones La presencia actual del analista es articulada respecto de su deseo. El cuerpo del analista permite actualizar, en la transferencia, el desplazamiento entre el registro yoico imaginario y el registro simbólico en el que emerge el sujeto.
Das vizinhanças entre o feminino e a loucura
Authors: Landi Elizabeth Cristina , Carvalho Isalena Santos , Chatelard Daniela Sheinkman
Published: April 2017

O tema da loucura feminina se apresenta frequentemente na clínica psicanalítica por meio de sujeitos neuróticos. Questiona-se neste artigo as proximidades entre psicose e a loucura que se apresenta no discurso das mulheres neuróticas. As identificações iniciais, por meio das quais a criança se aliena ao desejo do Outro, determinam certa loucura, não restrita apenas aos psicóticos. Para um sujeito do sexo feminino, que passa pelo tortuoso processo de tornar-se mulher, a loucura é uma possibilidade, pois uma mulher, por encontrar-se dividida entre o gozo masculino e o feminino, se aproxima da loucura, mas é não louca-de-todo.

ABSTRACT Objective: to assess the risk of falls in elderly, by comparing the sociodemographic and cognitive factors, history of falls and self-reported comorbidities. Method: cross-sectional and quantitative study with 240 elderly. Data were collected based on the social profile, through the instrument of risk of falls and assessment of falls, by univariate analysis, bivariate and multiple logistic regression. The Statistical Package for the Social Sciences (SPSS) version 19 was used for statistical analysis. Results: there was a significant association of the risk of falls, as measured by the Fall Risk Score, with sex (<0.001), age (0.054), cognitive status (<0.001) and history of falls (<0.001). All variables were statistically significant and contributed to the occurrence of falls. In logistic regression, the variables that showed association with risk of falls were: fall, with whom they live, hypertension and visual impairment. Conclusion: female gender, older elderly (over 80 years old), with low cognitive status and occurrence of previous falls in the last six months are factors that increase the prevalence of falls. In logistic regression, the variables that were associated with risk of falls were: fall, with whom they live, visual impairment and rheumatologic diseases.

ABSTRACT Objective: analyze trends in fertility rates and associations with perinatal outcomes for adolescents in Santa Catarina, Brazil. Methods: a population-based study covering 2006 to 2013 was carried out to evaluate associations between perinatal outcomes and age groups, using odds ratios, and Chi-squared tests. Results: differences in the fertility rate among female adolescents across regions and time period were observed, ranging from 40.9 to 72.0 per 1,000 in mothers aged 15-19 years. Adolescents had fewer prenatal care appointments than mothers ≥20 years, and a higher proportion had no partner. Mothers aged 15-19 years were more likely to experience preterm birth (OR:1.1; CI:1.08-1.13; p<0.001), have an infant with low birthweight (OR:1.1; CI:1.10-1.15; p<0.001) and low Apgar score at 5 minutes (OR:1.4; CI:1.34-1.45; p<0.001) than mothers ≥20 years, with the odds for adverse outcomes greater for those aged 10-14 years. Conclusion: this study provides evidence of fertility rates among adolescents remaining higher in regions of social and economic deprivation. Adolescent mothers and their infants more likely to experience adverse perinatal outcomes. Nurses, public health practitioners, health and social care professionals and educators need to work collaboratively to better target strategies for adolescents at greater risk; to help reduce fertility rates and improve outcomes.

Published: April 2017

Resumo O presente estudo buscou analisar a concepção de instrutores de esporte de aventura sobre o risco na prática do rapel vinculada a diferentes modalidades terrestres praticadas no estado de Minas Gerais. A partir de um estudo descritivo-exploratório com um grupo amostral composto por 35 instrutores (32 homens e 03 mulheres) verificou-se que os instrutores reconhecem o risco como elemento inerente à prática do rapel. Os sujeitos apontam o domínio da técnica, o estado dos equipamentos específicos, a adoção de tecnologias e a capacidade para decifrar informações referentes ao ambiente natural como forma de controlar e minimizar o risco. Chama atenção a postura dos instrutores participantes dessa investigação que, apesar de buscarem vivenciar fortes emoções, sensação de adrenalina e liberdade, colocam como princípio fundamental a manutenção da vida.
BARBÁRIE VERSUS CIVILIZAÇÃO: A PROBLEMÁTICA DA BILDUNG
Authors: Fortes Isabel
Published: April 2017

Resumo O artigo coteja a premissa freudiana do mal-estar da civilização com a leitura do conceito de semiformação em Adorno. Apresentam-se as ideias principais do ensaio “Teoria de la seudocultura” (Adorno, 1966), em que é proposto que a formação cultural (Bildung) afasta o homem da natureza e do corpo. A noção de semiformação pressupõe que a civilização teria, já em sua origem, o germe de seu colapso, pelo fato de buscar a dominação da natureza e do corpo. Desse modo, observamos que Adorno não é estranho a Freud quando concebe a violência instalada no cerne mesmo da civilização. Em 1930, Freud constata que não é mais possível partilhar do entusiasmo pela civilização como um bem precioso que conduziria todos os homens à mais elevada perfeição. Há um antagonismo entre as exigências da pulsão e as restrições da civilização que faz com que o conflito seja insolúvel e o desamparo, irremediável.
Hundred legs good, two fangs better: adult centipede (Scolopendridae) devoured by a juvenile Amazon lancehead, Bothrops atrox (Viperidae)
Authors: SILVA Karina Maria Pereira da , ALMEIDA-SANTOS Selma Maria de , BERTANI Rogério
Published: April 2017

ABSTRACT Centipedes are part of the diet of several snake species of the genus Bothrops. However, reports on predation of centipedes by snakes are normally incomplete, and important data for natural history studies as the species identification and size of the prey are rarely published. The aim of this work was to report the presence of the centipede Scolopendra viridicornis in the digestive tract of the Amazon pit viper B. atrox. The snake specimen is an immature female from Aripuanã, state of Mato Grosso, Brazil, having a 623 mm snout-vent length. The centipede is an adult Scolopendra viridicornis, estimated to be 190 mm long, and found in the snake's stomach. The success in preying on this large and potentially dangerous centipede could be explained by the snake's dimensions, large enough for overpowering the prey, but still retaining characteristics of youth, such as venom with specific action against specific prey items.
Couple formation and spawning between two female Discus Fish (Symphysodon aequifasciatus - Cichlidae) in captivity

ABSTRACT In an experiment performed to characterize the reproductive behavior of the discus fish in captivity, couple formation with two females was observed. The observations were carried out in captivity, based on ad libitum methodology. Adult individuals were allowed to naturally form couples. The couple formation was considered when individuals performed the substrate cleaning behavior. Fifteen couples were selected. The eggs of three couples did not initiate embryonic development and became infeasible within three days after spawning. We found that these spawnings belonged to all-female couples. The sex of the individuals in same-sex couples was confirmed through subsequent couple formation and spawning of fertile eggs with known males. Eggs were deposited by one or both females in the same-sex couples. Double spawnings were larger and differentially colored. The motivations that lead individuals of the same sex to form couples in this species are still unknown.
