To analyze the ametropy, way of acquisition, the care and complications related to contact lens wear among medical students from Faculdade de Medicina de Botucatu da Universidade Estadual Paulista-UNESP--Botucatu (SP). Questionnaire applied to students from the 1st to the 6th year of the Medical school of the Faculdade de Medicina de Botucatu da Universidade Estadual Paulista-UNESP--Botucatu (SP), forming an analytical cross-sectional survey. 27.4% of the students use contact lenses, and among them 94.8% use soft contact lenses and 98% have negative degree. 46.9% discard their contact lens monthly. 63.9% have an average daily use of 14 hours, 14.1% acquire the contact lenses from optician stores or at pharmacies and 46.5% of the students clean their contact lenses when they put them on and take them off. Regarding complications, 51.0% reported ocular redness; 44.5%, blurred vision; and 42.6%, foreign body sensation, whereas only 4 students reported "keratitis". We concluded that the inadequate adaptation that occurs even in users knowledgeable about this issue such as medical students, has increased the risk of complications. This fact indicates that more attention must be paid to contact lens care in order to prevent permanent visual deficit.

To determine the level of agreement with effective tobacco control measures recommended by the World Health Organization and to assess the attitudes toward, knowledge of, and beliefs regarding smoking among third-year medical students at University of São Paulo School of Medicine, located in the city of São Paulo, Brazil. Between 2008 and 2012, all third-year medical students were invited to complete a self-administered questionnaire based on the Global Health Professionals Student Survey and its additional modules. The study sample comprised 556 students. The level of agreement with the World Health Organization recommendations was high, except for the components "received smoking cessation training" and "raising taxes is effective to reduce the prevalence of smoking". Most of the students reported that they agree with banning tobacco product sales to minors (95%), believe that physicians are role models to their patients (84%), and believe that they should advise their patients to quit cigarette smoking (96%) and using other tobacco products (94%). Regarding smoking cessation methods, most of the students were found to know more about nicotine replacement therapy than about non-nicotine therapies (93% vs. 53%). Only 37% of the respondents were aware of the importance of educational antismoking materials, and only 31% reported that they believe in the effectiveness of encouraging their patients, during medical visits. In our sample, the prevalence of current cigarette smoking was 5.23%; however, 43.82% of the respondents reported having experimented with water-pipe tobacco smoking. Our results revealed the need to emphasize to third-year medical students the importance of raising the prices of and taxes on tobacco products. We also need to make students aware of the dangers of experimenting with tobacco products other than cigarettes, particularly water-pipe tobacco smoking.

Entre 2008 e 2012, todos os alunos do terceiro ano de medicina foram convidados a preencher um questionário autoaplicável baseado na Global Health Professions Student Survey e em seus módulos adicionais. A amostra consistiu em 556 estudantes. O grau de concordância com as recomendações da Organização Mundial da Saúde foi alto, à exceção de "receberam treinamento a respeito de cessação do tabagismo" e "aumentar os impostos é uma medida eficaz para reduzir a prevalência do tabagismo". A maioria dos estudantes relatou que concorda com a proibição da venda de produtos do tabaco a menores de idade (95%), acredita que os médicos são modelos de comportamento para seus pacientes (84%) e acredita que deveriam aconselhar seus pacientes a parar de fumar cigarros (96%) e de usar outros produtos do tabaco (94%). No tocante aos métodos de cessação do tabagismo, observamos que a maioria dos estudantes sabe mais sobre terapia de reposição da nicotina do que sobre terapias não nicotínicas (93% vs. 53%). Apenas 37% dos participantes estavam cientes da importância de material educacional antitabagismo, e apenas 31% relataram que acreditam na eficácia de incentivar seus pacientes, durante as consultas médicas, a parar de fumar. Em nossa amostra, a prevalência de tabagismo atual foi de 5,23%; entretanto, 43,82% dos participantes relataram ter experimentado fumar tabaco com um narguilé. Nossos resultados revelaram a necessidade de deixar claro para os alunos do terceiro ano de medicina o quão importante é aumentar os preços e impostos dos produtos do tabaco. É também preciso conscientizar os alunos dos perigos de experimentar outros produtos do tabaco que não os cigarros, particularmente o narguilé.

RIASSUNTO. L'Europa è la regione con il più forte consumo di alcol al mondo, con la più elevata percentuale di malattie totali e morti premature alcol-correlate. In Italia, questo fenomeno coinvolge circa il 13% della popolazione oltre i 18 anni e oltre il 25% dei pazienti ospedalizzati. Sfortunatamente, solo il 5% di questi pazienti vengono riconosciuti come persone affette da disturbo da uso di alcol (DUA). Una scarsa conoscenza della malattia, la mancanza di accesso alle cure e le poche risorse messe a disposizione nella gestione del problema sono tra le principali cause di ritardo nella diagnosi, alla fine con conseguenze cliniche molto più importanti e costose da gestire. Alla luce di ciò, abbiamo deciso di dedicare questo numero speciale della Rivista di psichiatria a una serie di articoli riguardanti le linee guida italiane per il trattamento della dipendenza da alcol. Realizzate in collaborazione con numerosi esperti e importanti società scientifiche italiane come il Centro di Riferimento Alcologico della Regione Lazio (CRARL), la Società Italiana Tossicodipendenze (SITD), la Società italiana per il Trattamento dell'Alcolismo e le sue Complicanze (SITAC), la Società Italiana Psichiatria delle Dipendenze (SIPDip), la Società Italiana Patologie da Dipendenza (SIPaD) e l'Istituto di Biologia Cellulare e Neurobiologia (IBCN-CNR), queste linee guida forniscono agli operatori una serie di raccomandazioni basate su prove di efficacia volte ad aumentare la conoscenza e un uso appropriato dei farmaci per le persone affette da DUA. Con la possibilità di un continuo aggiornamento, l'obiettivo principale di queste linee guida sarà quello di garantire l'omogeneità dei trattamenti e un incremento qualitativo nell'assistenza dei pazienti affetti da DUA, così da ridurre le conseguenze psicosociali e sulla salute pubblica di questa importante malattia psichiatrica.

To identify the profile of women seen in a Fetal Medicine unit, diagnosed with fetal abnormality incompatible with neonatal survival in their current pregnancy, and to check the association of gestational age upon diagnosis with the option of pregnancy termination. This is a retrospective cohort study carried out in the Fetal Medicine Outpatients Clinic of a university hospital, in the city of São Paulo (SP), Brazil, using medical records of pregnant women with fetus presenting abnormalities incompatible with neonatal survival. The sample comprised 94 medical records. The Statistical Package for the Social Sciences (SPSS), version 19, was used for the data statistical analysis. The population of the study included young adult women, who had complete or incomplete high school education, employed, with family income of one to three minimum wages, single, nonsmokers, who did not drink alcoholic beverages or used illicit drugs. Women with more advanced gestational age upon fetal diagnosis (p=0.0066) and/or upon admission to the specialized unit (p=0.0018) presented a lower percentage of termination of pregnancy. Due to characteristics different from those classically considered as of high gestational risk, these women might not be easily identified during the classification of gestational risk, what may contribute to a late diagnosis of fetal diseases. Early diagnosis enables access to specialized multiprofessional care in the proper time for couple's counseling on the possibility of requesting legal authorization for pregnancy termination. Identificar o perfil de mulheres atendidas em um serviço de Medicina Fetal, que receberam diagnóstico de anomalia fetal incompatível com a sobrevida neonatal na gestação atual, e verificar a associação da idade gestacional no diagnóstico com a opção pela interrupção da gravidez. Trata-se de um estudo de coorte retrospectivo, realizado no ambulatório de Medicina Fetal de um hospital universitário da cidade de São Paulo (SP), com prontuários de mulheres com fetos portadores de anomalias incompatíveis com a sobrevida neonatal na gestação atual. A amostra constituiu-se de 94 prontuários. Para análise estatística dos dados, utilizou-se o programa Statistical Package for the Social Sciences (SPSS), versão 19. A população foi de mulheres adultas jovens, com escolaridade compatível com o Ensino Médio completo/incompleto, empregadas, com renda familiar entre um e três salários mínimo, solteiras, que não faziam uso de tabaco, bebidas alcoólicas ou de drogas ilícitas. Verificou-se que mulheres com maior idade gestacional na ocasião do diagnóstico fetal (p=0,0066) e/ou na chegada ao serviço especializado (p=0,0018) apresentaram menor percentual de interrupção gestacional. Por apresentarem características diferentes daquelas classicamente consideradas de alto risco gestacional, é possível que essas mulheres não tenham sido facilmente identificadas durante a classificação de risco gestacional, o que pode ter colaborado para o diagnóstico tardio de patologias fetais. O diagnóstico precoce possibilita acesso à assistência multiprofissional especializada em tempo adequado para aconselhamento do casal sobre a possibilidade de solicitação de autorização judicial para a interrupção gestacional.

Myocardial infarction is the most significant manifestation of ischemic heart disease and is associated with high morbidity and mortality. Novel strategies targeting at regenerating the injured myocardium have been investigated, including gene therapy, cell therapy, and the use of growth factors. Growth factor therapy has aroused interest in cardiovascular medicine because of the regeneration mechanisms induced by these biomolecules, including angiogenesis, extracellular matrix remodeling, cardiomyocyte proliferation, stem-cell recruitment, and others. Together, these mechanisms promote myocardial repair and improvement of the cardiac function. This review aims to address the strategic role of growth factor therapy in cardiac regeneration, considering its innovative and multifactorial character in myocardial repair after ischemic injury. Different issues will be discussed, with emphasis on the regeneration mechanisms as a potential therapeutic resource mediated by growth factors, and the challenges to make these proteins therapeutically viable in the field of cardiology and regenerative medicine. Resumo O infarto do miocárdio representa a manifestação mais significativa da cardiopatia isquêmica e está associado a elevada morbimortalidade. Novas estratégias vêm sendo investigadas com o intuito de regenerar o miocárdio lesionado, incluindo a terapia gênica, a terapia celular e a utilização de fatores de crescimento. A terapia com fatores de crescimento despertou interesse em medicina cardiovascular, devido aos mecanismos de regeneração induzidos por essas biomoléculas, incluindo angiogênese, remodelamento da matriz extracelular, proliferação de cardiomiócitos e recrutamento de células-tronco, dentre outros. Em conjunto, tais mecanismos promovem a reparação do miocárdio e a melhora da função cardíaca. Esta revisão pretende abordar o papel estratégico da terapia, com fatores de crescimento, para a regeneração cardíaca, considerando seu caráter inovador e multifatorial sobre o reparo do miocárdio após dano isquêmico. Diferentes questões serão discutidas, destacando-se os mecanismos de regeneração como recurso terapêutico potencial mediado por fatores de crescimento e os desafios para tornar essas proteínas terapeuticamente viáveis no âmbito da cardiologia e da medicina regenerativa.

Homeopathy and acupuncture, although recognized as medical specializations in Brazil, are not taught in most medical schools. The objective was to evaluate undergraduate attitudes towards them following their inclusion as optional disciplines at Faculdade de Medicina da Universidade de São Paulo (FMUSP) in 2002. Questionnaire, at FMUSP. 484 students answered a self-administered questionnaire on these therapies, regarding their interest in learning, the teaching methods, their knowledge/experience (or that of someone close to them) and how it was acquired, the main indicators and general effectiveness of these therapies, and the possibilities for offering and integrating them within public healthcare units. Over 85% of the students considered that homeopathy and acupuncture should be included in curricula, as options (72%) or compulsorily (19%); 56% showed great interest in learning about them. Although 76% had little or no knowledge, 67% believed that these therapies had some effectiveness, and that chronic diseases (37%) or even chronic and acute diseases (29%) would be the main indicators for their use. Around 35% were receptive towards offering public primary care using both therapies, while 34% thought these treatments should also be available in hospitals and 60% believed they could be integrated with conventional medical practices. The medical students were interested in learning the principles of homeopathy and acupuncture, were able to observe and report on the effectiveness of these treatments and defended the use of these medical specializations within public healthcare.

Analysis of the documents of 2013 area graduate programs strict sense concerning the application and measurement of score the articles published, and creation of proposal for metric of the theme with the quadrennial review of Medicine III. Were evaluated the medicines area documents I, II and III; Biological Sciences (I) and Interdisciplinary, as well as the 2013 reports of CAPES. All programs establish metrics for "Classification of Published Articles" within its bibliographic production although with different percentages respecting its specificities. With these data collected and correlating their relevance with the surgical areas, was drafted proposal for quantification of the quality of the published articles to "Professional Postgraduate Programs" at surgical area that have specific characteristics according to their guidelines, directing their scientific production to technique journals preferably. The metric suggested for published articles, that should be included in intellectual production of the Area Document, should be considered for the extract A1 = 100 points; A2 = 85 points; B1 = 80 points; B2 = 70 points; B3 = 60 points; B4 = 40 points and B5 = 20 points. Propor métrica para qualificar a produção veiculada através de artigos publicados em programas de mestrado profissional e, a partir daí, estabelecer orientação para a avaliação dos programas de pós-graduação da Medicina III. Análise dos documentos de área de 2013 dos programas de pós-graduação senso estrito no que concerne à aplicação e mensuração de pontuação a artigos publicados, e criação de proposta para métrica do tema com vistas à avaliação quadrienal da Medicina III. Foram avaliados os documentos de área das Medicinas I, II e III; Ciências Biológicas I e Interdisciplinar, assim como os relatórios de 2013 da CAPES. Todos os programas estabelecem métrica para "Classificação de Artigos Publicados" dentro de sua produção bibliográfica embora com percentuais diferentes respeitando suas especificidades. Com esses dados levantados e correlacionando-se sua pertinência com as áreas cirúrgicas, foi elaborada proposta de quantificação da qualidade dos artigos publicados para "Programas de Pós-graduação Profissionais" na área cirúrgica que possuem características próprias de acordo com suas diretrízes, direcionando assim sua produção científica preferencialmente para revistas técnicas. A métrica sugerida para artigos publicados, que deve ser incluída na produção intelectual do Documento de Área, deverá ser considerada para o extrato A1 = 100 pontos; A2 = 85 pontos; B1 = 80 pontos; B2 = 70 pontos; B3 = 60 pontos; B4 = 40 pontos e B5 = 20 pontos.

O uso de polimeros naturais no ambito da preparacao de nanocompositos nao tem sido tao amplamente estudado quando comparado com os polimeros sinteticos. Assim, esta tese tem como objectivo estudar metodologias para a preparacao de novos materiais nanocompositos sob a forma de dispersoes e filmes utilizando polissacarideos como matriz. A tese esta dividida em cinco capitulos sendo o ultimo capitulo dedicado as conclusoes gerais e a sugestoes para trabalhos futuros. Inicialmente e apresentada uma breve revisao bibliografica sobre os principais temas colocando esta tese em contexto. Consideracoes sobre o uso de polimeros naturais e a sua combinacao com a utilizacao de nanoparticulas inorganicas para a fabricacao de novos bionanocomposites sao descritas e os objectivos e outline da tese sao tambem apresentados. No segundo capitulo, a preparacao de particulas de silica puras ou modificadas bem como a sua caracterizacao por FTIR, SEM, TEM, TGA, DLS (tamanho e potencial zeta) e medicoes de angulo de contacto sao discutidas. De modo a melhorar a compatibilidade da silica com os polissacarideos, as particulas SiO2 foram modificados com dois compostos do tipo organosilano: 3- metacril-oxipropil-trimetoxissilano (MPS) e 3-aminopropil-trimetoxissilano (APS). As particulas SiO2 MPS foram posteriormente encapsuladas com de poli(metacrilato de glicidilo) utilizando a tecnica de polimerizacao em emulsao. A utilizacao dos nanocompositos resultantes na preparacao de dispersoes de bionanocompositos nao foi bem sucedida e por esse motivo nao os estudos nao foram prosseguidos. O uso de SiO2 APS na preparacao de dispersoes bionanocomposite foi eficiente. No terceiro capitulo e apresentada uma revisao sobre dispersoes bionanocompositas e respectiva caracterizacao destacando aspectos fundamentais sobre reologia e microestrutura. Em seguida, e discutido o estudo sistematico realizado sobre o comportamento reologico de dispersoes de SiO2 utilizando tres polissacarideos distintos no que concerne a carga e as caracteristicas gelificantes: a goma de alfarroba (nao ionica), o quitosano (cationico) e a goma xantana (anionica) cujas propriedades reologicas sao amplamente conhecidas. Os estudos reologicos realizados sob diferentes condicoes demonstraram que a formacao de geis frageis e/ou bem estruturados depende do tamanho SiO2, da concentracao, do pH e da forca ionica. Estes estudos foram confirmados por analises microestruturais usando a microscopia electronica a baixas temperaturas (Cryo-SEM). No quarto capitulo, sao apresentados os estudos relativos a preparacao e caracterizacao de filmes bionanocompositos utilizando quitosano como matriz. Primeiramente e apresentada uma revisao sobre filmes de bionanocompositos e os aspectos fundamentais das tecnicas de caracterizacao utilizadas. A escolha do plasticizante e da sua concentracao sao discutidas com base nas propriedades de filmes de quitosano preparados. Em seguida, o efeito da concentracao de silica e dos metodos utilizados para a dispersar na matriz de polissacarideo, bem como o efeito da modificacao da superficie da silica e avaliado. As caracteristicas da superficie e as propriedades de barreira, mecanicas e termicas sao discutidas para cada conjunto de filmes preparados antes e apos a sua neutralizacao. Os resultados obtidos mostraram que a dispersao das cargas no plasticizante e posterior adicao a matriz polissacaridica resultaram apenas em pequenas melhorias ja que o problema da agregacao de silica nao foi ultrapassado. Por esse motivo foram preparados filmes com SiO2 APS os quais apresentaram propriedades melhores apesar da agregacao das particulas nao ter sido completamente impedida. Tal pode estar relacionado com o processo de secagem dos filmes. Finalmente, no capitulo 5, sao apresentadas as principais conclusoes obtidas e algumas sugestoes para trabalho futuro.

To evaluate mouthpiece ventilation (MPV) in patients with Duchenne muscular dystrophy (DMD) who are noncompliant with noninvasive ventilation (NIV). We evaluated four young patients with DMD who had previously refused to undergo NIV. Each patient was reassessed and encouraged to try MPV. The four patients tolerated MPV well and were compliant with NIV at home. MPV proved to be preferable and more comfortable than NIV with any other type of interface. Two of the patients required overnight NIV and eventually agreed to use a nasal mask during the night. The advantages of MPV over other types of NIV include fewer speech problems, better appearance, and less impact on the patient, eliminating the risk of skin breakdown, gastric distension, conjunctivitis, and claustrophobia. The use of a mouthpiece interface should be always considered in patients with DMD who need to start NIV, in order to promote a positive approach and a rapid acceptance of NIV. Using MPV during the daytime makes patients feel safe and more likely to use NIV at night. In addition, MPV increases treatment compliance for those who refuse to use other types of interfaces. Avaliar a ventilação bucal (VB) em pacientes com distrofia muscular de Duchenne (DMD) não aderentes à ventilação não invasiva (VNI). Foram avaliados quatro pacientes jovens com DMD que anteriormente recusaram-se a se submeter à VNI. Cada paciente foi reavaliado e encorajado a tentar VB. Os quatro pacientes toleraram bem a VB e aderiram ao uso de VNI em casa. O uso de VB provou ser uma alternativa preferível e mais confortável que o uso de VNI com qualquer outro tipo de interface. Dois dos pacientes necessitaram de VNI noturna e eventualmente aceitaram utilizar uma máscara nasal durante a noite. As vantagens da VB sobre outros tipos de VNI incluem menores problemas na fala, melhor aparência e menor impacto no paciente, eliminando o risco de lesões na pele, distensão gástrica, conjuntivite e claustrofobia. O uso da interface bucal sempre deve ser considerado em pacientes com DMD que necessitam iniciar VNI a fim de promover uma abordagem positiva e uma rápida aceitação da VNI. O uso diurno de VB faz com que os pacientes sintam-se seguros e mais propensos a utilizar VNI à noite. Além disso, a VB aumenta a adesão ao tratamento naqueles pacientes que se recusam a utilizar outros tipos de interfaces.

Resumo A doença aterosclerótica das carótidas extracranianas pode resultar em complicações com alta morbidade e mortalidade. A avaliação pré-operatória com exames contrastados de imagem é associada a complicações como a parotidite, além das já bem conhecidas reações alérgicas e da disfunção renal. A bifurcação carotídea alta e a doença aterosclerótica de extensão cranial costumam ser fatores limitantes para o tratamento cirúrgico convencional. Entretanto, quando há contraindicação ao uso de contraste iodado ou impossibilidade do tratamento endovascular, há a necessidade do conhecimento de técnicas cirúrgicas que permitam a realização da endarterectomia com segurança. A subluxação da mandíbula se mostrou uma técnica adjuvante segura e efetiva, de fácil execução e reprodutibilidade, possibilitando o acesso a bifurcações carotídeas altas com boa exposição do campo cirúrgico e permitindo a realização da endarterectomia conforme a técnica padrão. Apresentamos o caso de uma paciente com bifurcação carotídea alta e com limitações para uso do contraste iodado que foi submetida a endarterectomia carotídea após subluxação de mandíbula.

To understand the meanings that male university students assign to the condition of users of alcohol and other drugs. An exploratory study using a qualitative approach, with inductive analysis of the content of semi-structured interviews applied to 20 male university students from a public university in the southeast region of Brazil, grounded on the theoretical-methodological referential of interpretive anthropology and ethnographic method. Data were construed using content inductive analysis for two topics: use of alcohol and/or drugs as an outlet; and use of alcohol and/or other drugs: an alternative for belonging and identity. Male university students share the rules of their sociocultural environment that values the use of alcohol and/or other drugs as a way of dealing with the demands and stress ensuing from the everyday university life, and to build identity and belong to this social context, reinforcing the influence of culture. Compreender os significados atribuídos pelos universitários do sexo masculino à condição de usuários de álcool e outras drogas. Estudo exploratório de abordagem qualitativa, com análise de conteúdo indutiva de entrevistas semiestruturadas de 20 universitários do sexo masculino, matriculados em uma universidade pública da região sudeste do Brasil, fundamentado no referencial teórico-metodológico da Antropologia Interpretativa e do método etnográfico. Os dados foram interpretados com a análise de conteúdo indutiva em dois temas: O uso do álcool e/ou drogas como válvula de escape; O uso do álcool e/ou outras drogas: alternativa para o pertencimento e para a identidade. Os universitários do sexo masculino compartilham normas de seu meio sociocultural, que valorizam o uso de álcool e/ou outras drogas, como uma forma de lidar com as exigências e o estresse da vida universitária, criar uma identidade e ter pertencimento neste contexto social, reforçando a influência da cultura.

An experiment on VLBI radar of the 2012 DA14 asteroid was carried out on February 15-16, 2011 at the time of its closest approach to the Earth. The research teams of Kharkov (Institute of Radio Astronomy of the National Academy of Sciences of Ukraine), Evpatoria (National Space Facilities Control and Test Center), Nizhny Novgorod (Radiophysical Research Institute), Bologna (Istituto di Radioastronomia (INAF)), and Ventspils (Ventspils International Radioastronomy Center) took part in the experiment. The asteroid was irradiated by the RT-70 planetary radar (Evpatoria) at a frequency of 5 GHz. The reflected signal was received using two 32-m radio telescopes in Medicina (Italy) and Irbene (Latvia) in radiointerferometric mode. The Doppler frequency shifts in bi-static radar mode and interference frequency in VLBI mode were measured. Accuracy of the VLBI radar method for determining the radial and angular velocities of the asteroid were estimated.

Intravenous amphotericin B deoxycholate (AmB-D) infusions, usually given over 4 hours, frequently induce nephrotoxicity and undesirable infusion-related side effects such as rigors and chills. There is evidence in the literature that the use of AmB-D in the form of continuous 24-hour infusion is less toxic than the usual four-hour infusion of this drug. Our objective was to evaluate the efficacy and safety of continuous infusion of AmB-D for the treatment of persistent fever in neutropenic patients with hematological malignancies after chemotherapy. Observational retrospective analysis of our experience with continuous infusion of AmB-D, at Faculdade de Medicina da Fundação ABC and Hospital Estadual Mário Covas in Santo André. From October 2003 to May 2004, 12 patients with hematological malignancies and chemotherapy-induced neutropenia received 13 cycles of continuous infusion of AmB-D. The median dose of AmB-D was 0.84 mg/kg/day (0.33 to 2.30 mg/kg/day). Concomitant use of nephrotoxic medications occurred in 92% of the cycles. Nephrotoxicity occurred in 30.76% of the cycles, hypokalemia in 16.67%, hepatotoxicity in 30% and adverse infusion-related events in 23%. All patients survived for at least seven days after starting continuous infusion of AmB-D, and clinical resolution occurred in 76% of the cycles. Continuous infusion of AmB-D can be used in our Institution as an alternative to the more toxic four-hour infusion of AmB-D and possibly also as an alternative to the more expensive liposomal formulations of the drug.

En la investigación con animales existen cuestionamientos éticos tanto en el uso como modelos de enfermedades humanas y requisito previo para ensayos en humanos como en la introducción de modificaciones genéticas. Algunos de estos cuestionamientos son: no representar exactamente la condición humana como modelos, realizar pruebas de toxicidad con grave daño para los animales, alterar su naturaleza mediante modificaciones genéticas, riesgos de la introducción de organismos genéticamente modificados. El uso de animales en investigación para beneficio humano, impone al ser humano la responsabilidad moral de respetarlo, no haciéndoles sufrir innecesariamente, al estar trabajando con seres vivientes y sentientes.

There are few authors focused on the study of preparing manuals criteria, often criticized for methodological rigor of the information. However, it is interesting to understand what is going wrong; to understand prognosis in self-handling; in prevention of complications; in identifying better services and information; in encouraging the pursuit of excellence in the healthcare. In its preparation should be valued the basic requirements of a manual, which are: 1) wrote in simple words, being concise, efficient, clear with index or table of contents; 2) using the existing institutional rules; 3) being flexible; and 4) having ongoing process of review, update and distribution. In the process of evaluation of Medicine III manuals may have the following stratification: M4 - 100 points: when there is ISBN registration and disclosure in other languages; M3 - 75 points: registration with the ISBN only in our country; M2 - 50 points: registered in regional libraries; M1 - 25 points: manual use for inter-departmental or intra-institutional groups; M0 - 0 point: use of manual in intra-departmental teaching. In conclusion, it is known that the use of manuals is focused to the ones who do not know the subject; however, it is also an important tool that can minimize errors, avoid professional misconduct, optimize resources, and at the end allowing assessment of the subject at hand. Poucos são os autores que se debruçam no estudo dos critérios de elaboração de manuais, sendo muitas vezes criticados pelo rigor metodológico das informações. Contudo, eles são interessantes no entender o que é errado, compreender prognóstico, na autoassistência, na prevenção de complicações, para identificar melhores serviços e informações, motivando a busca pela excelência no atendimento assistencial. Em sua elaboração devem ser valorizados os requisitos básicos de um manual, que são: 1) conter redação simples, concisa, eficiente e clara, contendo índice ou sumário; 2) utilizar as normas institucionais vigentes; 3) serem flexíveis; e 4) ter processo contínuo de revisão, atualização e distribuição. No processo de avaliação da Medicina III poderá ter os seguintes estratos: M4 - 100 pontos: registro no ISBN e divulgação em outros idiomas; M3 - 75 pontos: registro no ISBN apenas em nível nacional; M2 - 50 pontos: registrado em bibliotecas regionais; M1 - 25 pontos: manual de uso intrainstitucional por grupos interdepartamentais; M0 - 0 ponto: manual de uso intradepartamental ou de ensino. Em conclusão, sabe-se que o uso de manuais está destinado a quem não sabe do assunto; no entanto, trata-se de ferramenta importante que pode minimizar erros, consolidar condutas, otimizar recursos, permitindo avaliação criteriosa e aprofundada do tema em pauta.

To analyze the existence of differences in the use of generic medicines in Brazil according to demographic and socioeconomic variables and acquisition sources of the medicines. Population-based cross-sectional study, conducted with data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines). Data collection took place between September, 2013 and February, 2014 in homes of Brazilian cities (urban area). The use of medicines has been investigated in relation to the treatment of chronic diseases and, in the case of acute events, regarding use over the previous 15 days. Generics were identified by visualization of packaging presented by the users of the medicines. The independent variables used were sex, age, education level, economic class, and region of the Country. The statistical significance of differences between the groups was evaluated by Pearson's Chi-squared test, considering a 5% significance level. The prevalence of generic medicines use was 45.5% (95%CI 43.7-47.3). There was no difference considering education level. The prevalence was higher in females (47.0%; 95%CI 44.9-49.0) than in males (43.1%; 95%CI 40.5-45.8), and were higher with increasing age. Generic medicines were more used in the economic class C (47.0%; 95%CI 44.9-49.1) and in the South (50.6%; 95%CI 46.6-54.6) and Southeast (49.9%; 95%CI 46.8-53.0) regions. Generics accounted for 37.3% of the medicines provided by the Brazilian Unified Health System. Currently, there is a choice of purchase or free provision by the Brazilian Unified Health System, characterized by quality assurance and reduced price regarding branded medicines considered as reference. In the private market, a considerable part of the population is choosing generic medicines thanks to the availability of this option for virtually all medicines most used by the population. Analisar se há diferença no uso de medicamentos genéricos no Brasil segundo variáveis demográficas, socioeconômicas e fontes de obtenção dos medicamentos. Estudo transversal de base populacional, conduzido com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), com coleta de dados entre setembro de 2013 e fevereiro de 2014 em residências de municípios brasileiros urbanos. O uso dos medicamentos foi investigado em relação ao tratamento de doenças crônicas e, no caso de eventos agudos, quanto ao uso nos últimos 15 dias. Os genéricos foram identificados por visualização das embalagens apresentadas pelos usuários dos medicamentos. As variáveis independentes utilizadas foram sexo, idade, escolaridade, classe econômica e região do País. A avaliação da significância estatística das diferenças entre os grupos foi analisada pelo teste Qui-quadrado de Pearson, considerando nível de significância de 5%. A prevalência de uso de genéricos foi de 45,5% (IC95% 43,7-47,3). Não houve diferença por escolaridade, as prevalências foram maiores no sexo feminino (47,0%; IC95% 44,9-49,0) em relação ao masculino (43,1%; IC95% 40,5-45,8) e foram crescentes com o aumento da idade. Maiores usos de genéricos foram encontrados na classe econômica C (47,0%; IC95% 44,9-49,1) e nas regiões Sul (50,6%; IC95% 46,6-54,6) e Sudeste (49,9%; IC95% 46,8-53,0). Observou-se ainda que os genéricos representaram 37,3% dos medicamentos disponibilizados pelo Sistema Único de Saúde . Pode-se concluir que hoje existe uma alternativa de compra ou fornecimento gratuito pelo Sistema Único de Saúde, caracterizada por garantia de qualidade e preço reduzido em relação aos medicamentos de marca comercial considerados como referência. No mercado privado, boa parte da população está optando pelo uso de medicamentos genéricos, graças à disponibilidade dessa opção para praticamente todos os medicamentos mais utilizados pela população.

This paper describes the development process of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines) based on an integrated approach to pharmaceutical services, science, technology and innovation. It starts by contextualizing health and development in Brazil and features elements of the National Policy for Science, Technology and Innovation in Health in Brazil and the National Policy for Pharmaceutical Services. On presenting pharmaceutical policy guidelines, it stresses the lack of nationwide data. This survey, commissioned by the Brazilian Ministry of Health, has two components: household survey and evaluation of pharmaceutical services in primary care. The findings point to perspectives that represent, besides the enhancement of public policy for pharmaceutical services and public health, results of government action aimed at developing the economic and industrial health care complex to improve the health conditions of the Brazilian population. RESUMO O artigo apresenta o processo de construção da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamento a partir de uma concepção integradora da Assistência Farmacêutica, Ciência, Tecnologia e Inovação. Inicia-se contextualizando a saúde e o desenvolvimento no País e apresenta elementos da Política Nacional de Ciência Tecnologia e Inovação em Saúde no Brasil e da Política Nacional de Assistência Farmacêutica. Ao apresentar as diretrizes das Políticas Farmacêuticas, destaca-se a carência de dados de abrangência nacional. A presente pesquisa, encomendada pelo Ministério da Saúde, foi estruturada em dois componentes: inquérito domiciliar e avaliação dos serviços de assistência farmacêutica na atenção básica. As perspectivas dos resultados representam, além do incremento das políticas públicas farmacêuticas e de saúde pública, resultados de ações governamentais voltadas ao desenvolvimento do complexo econômico-industrial da saúde, visando a melhoria das condições de saúde da população brasileira.

RIASSUNTO. L'elaborazione del piano di trattamento rappresenta un momento molto delicato e complesso del processo terapeutico del disturbo da abuso di alcol (DUA). È la fase in cui le informazioni raccolte da un'équipe di professionisti (medici, psicologi e assistenti sociali) (modello bio-psico-sociale del DUA) vengono messe insieme per decidere il percorso terapeutico più adatto. Per quanto riguarda la parte psicologica, è di notevole importanza scegliere un trattamento clinico in grado di ridurre al minimo la mancata adesione al trattamento e, per i soggetti che rimangono in trattamento, di garantirne l'efficacia. Se da una parte, le tecniche psicoanalitiche e comportamentali hanno fornito le basi della terapia psicologica dell'alcolismo, dall'altra, gli approcci basati sull'evidenza scientifica sono stati elaborati a partire dai principi del colloquio motivazionale e della terapia cognitivo-comportamentale. In questo articolo viene fornita una panoramica dei trattamenti che sono risultati più efficaci nel trattare il DUA e delle modalità temporali più adeguate per monitorare l'efficacia del trattamento.

Existe um gradiente radial de abundâncias no disco galáctico, cujo comportamento é razoavelmente bem conhecido para distâncias galactocêntricas entre 3 e 10 kpc. Foi obtido a partir de resultados derivados de nebulosas planetárias, regiões HII e estrelas, como as estrelas quentes de tipo O, B e aglomerados abertos. Com o objetivo de investigar o comportamento deste gradiente radial na região externa do disco, conhecida como anticentro galáctico, reportamos aqui os resultados finais da análise de uma amostra de nebulosas planetárias na direção do anticentro, observadas no LNA e no ESO entre 1995 e 2000. O uso de nebulosas planetárias permite o cálculo das abundâncias de elementos traçadores da evolução química do disco como oxigênio, argônio e neônio com o uso de técnicas de espectroscopia nebular. Os resultados indicam uma distribuição de abundâncias distinta daquela encontrada na vizinhança solar, mostrando que o gradiente radial diminui sensivelmente para distâncias galactocêntricas maiores que 10 kpc. Este resultado está de acordo com os mais recentes modelos de evolução química do disco, que prevêem uma diminuição ou mesmo um desaparecimento do gradiente radial no bordo externo do disco galáctico.

A principal ferramenta de trabalho do astrônomo é o telescópio. O manuseio do mesmo é sempre motivo de enorme curiosidade por parte de alunos do ensino fundamental ou médio e até mesmo dos respectivos professores. Visando propiciar o acesso de alunos e professores ou interessados em geral a uma luneta de fácil construção, com materiais alternativos, de fácil localização no comércio, de baixo custo, resistente ao manuseio de alunos, simplificamos a montagem de uma luneta construída com lente de óculos, de 1 ou 2 graus positivos, e monóculo de fotografia, publicado por este autor no CCEF, vol.11(3), 212, 1994. Esta luneta, a qual permite ver as crateras lunares, apresentava como maior dificuldade de construção o tripé e o local de formação da imagem. Substituímos o tripé de madeira por uma simples garrafa PET de 2 litros cheia d'água. No lugar da ocular usamos a lente do monóculo de fotografia (ou visor de fotografia) encaixado dentro de uma bucha de redução curta, de 40 x 32 mm, e esta não mais dentro de uma luva (conexão hidráulica) de 40 mm de diâmetro, mas sim encostada no próprio tubo de PVC móvel (o qual permite o ajuste do foco) de 40 mm de diâmetro e presa a este por outro tubo de 40 mm de diâmetro e 10 cm de comprimento, serrado ao longo do seu comprimento. Com isto podemos ajustar a posição deste tubo de 10 cm também para que uma das suas extremidades coincida com o local de formação da imagem. Desta forma o observador saberá o local exato da formação da imagem, o que não era evidente na montagem anterior e causava uma dificuldade inicial até se descobrir a posição exata em que se deveria colocar o olho. Deste maneira, a montagem inicial que já era simples ficou ainda mais simples, mais barata e mais confortável para o uso. Um exemplar da mesma será exposto durante a XXIX Reunião Anual da Sociedade Astronômica Brasileira para inspeção e uso dos participantes.

A industria aeronautica utiliza ligas de aluminio de alta resistencia para o fabrico dos elementos estruturais dos avioes. As ligas usadas possuem excelentes propriedades mecanicas mas apresentam simultaneamente uma grande tendencia para a corrosao. Por esta razao essas ligas necessitam de proteccao anticorrosiva eficaz para poderem ser utilizadas com seguranca. Ate a data, os sistemas anticorrosivos mais eficazes para ligas de aluminio contem cromio hexavalente na sua composicao, sejam pre-tratamentos, camadas de conversao ou pigmentos anticorrosivos. O reconhecimento dos efeitos carcinogenicos do cromio hexavalente levou ao aparecimento de legislacao banindo o uso desta forma de cromio pela industria. Esta decisao trouxe a necessidade de encontrar alternativas ambientalmente inocuas mas igualmente eficazes. O principal objectivo do presente trabalho e o desenvolvimento de pretratamentos anticorrosivos activos para a liga de aluminio 2024, baseados em revestimentos hibridos produzidos pelo metodo sol-gel. Estes revestimentos deverao possuir boa aderencia ao substrato metalico, boas propriedades barreira e capacidade anticorrosiva activa. A proteccao activa pode ser alcancada atraves da incorporacao de inibidores anticorrosivos no pretratamento. O objectivo foi atingido atraves de uma sucessao de etapas. Primeiro investigou-se em detalhe a corrosao localizada (por picada) da liga de aluminio 2024. Os resultados obtidos permitiram uma melhor compreensao da susceptibilidade desta liga a processos de corrosao localizada. Estudaram-se tambem varios possiveis inibidores de corrosao usando tecnicas electroquimicas e microestruturais. Numa segunda etapa desenvolveram-se revestimentos anticorrosivos hibridos organico-inorganico baseados no metodo sol-gel. Compostos derivados de titania e zirconia foram combinados com siloxanos organofuncionais a fim de obter-se boa aderencia entre o revestimento e o substrato metalico assim como boas propriedades barreira. Testes industriais mostraram que estes novos revestimentos sao compativeis com os esquemas de pintura convencionais actualmente em uso. A estabilidade e o prazo de validade das formulacoes foram optimizados modificando a temperatura de armazenamento e a quantidade de agua usada durante a sintese. As formulacoes sol-gel foram dopadas com os inibidores seleccionados durante a primeira etapa e as propriedades anticorrosivas passivas e activas dos revestimentos obtidos foram estudadas numa terceira etapa do trabalho. Os resultados comprovam a influencia dos inibidores nas propriedades anticorrosivas dos revestimentos sol-gel. Em alguns casos a accao activa dos inibidores combinou-se com a proteccao passiva dada pelo revestimento mas noutros casos tera ocorrido interaccao quimica entre o inibidor e a matriz de sol-gel, de onde resultou a perda de propriedades protectoras do sistema combinado. Atendendo aos problemas provocados pela adicao directa dos inibidores na formulacao sol-gel procurou-se, numa quarta etapa, formas alternativas de incorporacao. Na primeira, produziu-se uma camada de titania nanoporosa na superficie da liga metalica que serviu de reservatorio para os inibidores. O revestimento sol-gel foi aplicado por cima da camada nanoporosa. Os inibidores armazenados nos poros actuam quando o substrato fica exposto ao ambiente agressivo. Numa segunda, os inibidores foram armazenados em nano-reservatorios de silica ou em nanoargilas (halloysite), os quais foram revestidos por polielectrolitos montados camada a camada. A terceira alternativa consistiu no uso de nano-fios de molibdato de cerio amorfo como inibidores anticorrosivos nanoparticulados. Os nano-reservatorios foram incorporados durante a sintese do sol-gel. Qualquer das abordagens permitiu eliminar o efeito negativo do inibidor sobre a estabilidade da matriz do sol-gel. Os revestimentos sol-gel desenvolvidos neste trabalho apresentaram proteccao anticorrosiva activa e capacidade de auto-reparacao. Os resultados obtidos mostraram o elevado potencial destes revestimentos para a proteccao anticorrosiva da liga de aluminio 2024.

To update knowledge and methods to access and view the journals included in Qualis of CAPES Medicine III, and how to measure the impact factor. Document review on the attempt to verify the way Qualis uses for ranking journals cited by the post-graduate programs of Medicine III in their evaluation periods, and the impact factors obtained by journals indexing base. The classification is annual and are ranking in strata ranging from A1, the highest, and A2; B1; B2; B3; B4; B5; C. The latter has zero evaluation weight. These strata take as reference the impact factor of the journals listed by the programs. The same journal can be classified into different Qualis in other areas, and this is no inconsistency, but expressed the assigned value, in each area, at that particular journal. The Impact Factor is measured using the Journal of Citation Report in Web of Knowledge website. Using the criteria established by WebQualis for stratification of journals there is a quality guidance of what is produced by the program and, based on it, can be made scientific comparison of program performance. Consulting the JCR is recommended because it defines exactly what is the journal's impact factor; Qualis stratifies numerical intervals and not individual journal specificity. Atualização do conhecimento dos meios e métodos de acessar e visualizar os periódicos do Qualis da Medicina III da CAPES e a mensuração do Fator de Impacto. Buscou-se verificar a forma utilizada pelo Qualis para classificar os periódicos referidos pelos programas de pós-graduação da Medicina III em seus períodos de avaliação e os fatores de impacto obtidos pelas revistas em base indexadora. A classificação é anual e são enquadrados em estratos que variam de A1, o mais elevado, a A2; B1; B2; B3; B4; B5; C. Este último tem peso zero. Esses estratos levam como referência o Fator de Impacto dos periódicos referidos pelos programas. Um mesmo periódico pode ter classificação em Qualis diferentes em outras áreas, e isto não constitui inconsistência, mas expressa o valor atribuído, em cada área, àquela determinada revista científica. O Fator de Impacto é mensurado navegando-se no site do Journal of Citation Report da Web of Knowledge. A utilização dos critérios estabelecidos pelo WebQualis para estratificação dos periódicos é norteadora da qualidade do que se produz nos programas e, com base nela, pode-se fazer comparações de desempenho científico. Já a consulta ao JCR é complementarmente adequada de ser feita porque define com exatidão qual é o fator de impacto da revista, em função de que o Qualis estratifica faixas numéricas e não especificidade individual do periódico.

Resumo Define-se trombose induzida pelo calor endovenoso como a propagação do trombo a partir de uma veia superficial em direção a uma veia mais profunda. Em geral, é considerada clinicamente insignificante quando não há propagação do trombo para o sistema venoso profundo. Essa condição pode ser tratada com terapia anticoagulante, embora a observação pareça ser suficiente, principalmente para graus menores. Neste estudo, relatamos dois casos de trombose induzida pelo calor endovenoso que teriam indicação de heparina de baixo peso molecular até a resolução do quadro. Porém, optou-se pelo uso da rivaroxabana (15 mg de 12 em 12h), com resolução completa do trombo em 4 semanas (caso 1) e em 7 dias (caso 2). A rivaroxabana pode ser uma alternativa promissora no tratamento da trombose induzida pelo calor endovenoso avançada, pela simplicidade da posologia, sem comprometimento da eficácia ou da segurança. São necessários estudos prospectivos, randomizados e controlados que possibilitem melhor entendimento da condição e o desenvolvimento de recomendações mais definitivas sobre opções de prevenção e tratamento.

CRITERIA FOR CONSULTANT AND ADVISOR IN THE BRAZILIAN POSTGRADUATE SYSTEM.

To review the rules, resolutions and existing documents relating to consultant and advisor to better target the actions of those who exercise these roles. The following documents were consulted: Statute of CAPES, through Decree No. 7692 of March 2, 2012; Ordinance No. 47 of 17/10/1995; Opinion 977 1965 Newton Sucupira; Area Document of Medicine III; Interministerial Ordinance 251 of 2012, based on Decree No. 7642 of 2011 of the Ministry of Science and Technology; CAPES Regiment. The Brazilian Postgraduate system is divided in two different fields, according to its aspects: the "lato sensu" postgraduate, defined as all professional studies performed after the high school graduation; and the "stricto sensu" postgraduate that includes the master degree and the doctorate, both of them different from what is known as MSc or MS and PhD. The Brazilian doctorate is recognized as academic because its purposes include to improve the scientific and the teaching levels of university docents. The master degree has two different objectives one is to be academic and similar to the doctorate; the other is to upgrade professionals to a higher level than specialist or MBA and is denominated professional master degree. The master degrees and the doctorate are designated as courses and may be put together in a structure known as stricto sensu postgraduate program. The complexity of these courses and programs in all the areas of the superior human knowledge requires a large number of professional directly involved with this system and other professionals that attend them, called consultants and advisors. The consultants are counselors, and the advisors are assistants, both of them legally established with the incumbency to aid the postgraduate staff in all their duties. Nothing prevents a person from being a consultant on the situation and advisor on another, even in the same institution. Have knowledge about what being a consultant and advisor is required to exercise the function within the limits and dimension that the wingspan of the professional allows. Revisar as normas, resoluções e documentos vigentes relativos ao tema consultoria e assessoria para melhor orientar as atuações de quem exerce esses papéis. Foram consultados os seguintes documentos: Estatuto da CAPES, por meio do Decreto Nº 7.692, de 02 de março de 2012; Portaria nº 47 de 17/10/1995; Parecer 977 de 1965 de Newton Sucupira; Documento de Área da Medicina III; Portaria Interministerial 251 de 2012, com base no Decreto nº 7642 de 2011 do Ministério de Ciência e Tecnologia; e Regimento da CAPES. O gerenciamento dos programas de pós-graduação stricto sensu requer estrutura multiprofissional diversificada em todos os seus níveis, constituída por corpo próprio da instituição e por componentes agregados, incluindo os consultores e assessores. O consultor é pessoa independente, sem vínculo com quem o convida e, nesse sentido, espera-se dele isenção na execução das tarefas solicitadas, nas quais se pressupõe domínio cultural, científico e humanístico. No Documento de Área da Medicina III, a consultoria é valorizada como atributo importante do Corpo Docente e está mencionada na Proposta dos Programas de Pós-graduação em seu item 2.1. Por outro lado, o assessor está vinculado ao solicitante em relação de dependência funcional. Dentro de sua área do conhecimento, o assessor é considerado adjunto do solicitante e pode substituí-lo ou representá-lo. No Documento de Área da Medicina III, o desempenho de assessoria pelo Corpo Docente está mencionado na Proposta dos Programas de Pós-graduação em seu item 5.2. Ter conhecimento sobre o que significa ser consultor e assessor é necessário para exercer a função dentro dos limites que lhe compete e na dimensão que a envergadura do profissional permite. Nada impede que uma pessoa seja consultora em situação e assessora em outra, até na mesma instituição. Ter conhecimento sobre o que significa ser consultor e assessor é necessário para poder exercer a função dentro dos limites que lhe compete e na dimensão que a envergadura do profissional permite.

RIASSUNTO. Il fenomeno delle persone senza fissa dimora sta assumendo in questi anni una rilevanza sociale devastante, con una prevalenza stimata in USA e in Europa compresa tra il 5,6% e il 13,9%. Queste persone hanno una scarsa qualità di vita, una limitata o assente vita sociale, sono spesso disoccupate o lavorano solo saltuariamente. Sono a rischio di problemi con la legge, sono spesso affette da dipendenza da droghe, da patologie psichiatriche e internistiche. L'alcol spesso non rappresenta la causa della loro condizione sociale, ma solo la conseguenza, contribuendo in questo modo al loro degrado bio-psico-sociale. Nel 2009 lo US Department of Housing and Urban Development's Homelessness Assistance Programs e nel 2010 la European Consensus Conference on Homelessness hanno segnato un grande passo avanti nella riabilitazione sociale di queste persone, utilizzando il concetto del "case management". In particolare lo Standard Case Management si è dimostrato in grado di migliorare la stabilità abitativa, di ridurre l'uso di droghe e di rimuovere le barriere lavorative. L'Assertive Community Treatment si è dimostrato, invece, in grado di migliorare la stabilità abitativa e ha un rapporto costo/beneficio migliore per i pazienti affetti da doppia diagnosi.

Um interessante fenômeno lingüístico presente nas interações das pessoas bilíngues é a alternância de línguas. Neste trabalho, estamos investigando a alternância entre a língua portuguesa oral e a língua de sinais brasileira – Libras, numa mesma cadeia enunciativa, com o objetivo de identificar e analisar o uso dessa alternância na fala de uma criança e de um adulto (ambos ouvintes, filhos de pais surdos), interagindo em uma situação de bilinguismo intermodal, com interlocutores surdos e ouvintes. A alternância de línguas, nesse caso, ocorre quando se para de falar em português e se alterna para sinalizar. O presente trabalho se caracteriza como um estudo inicial, com análise qualitativa de dados. Fazem parte do nosso corpus nove sessões de interações em Libras e em português oral, gravadas em vídeo, que fazem parte do Projeto Desenvolvimento Bilíngue Bimodal da UFSC. Os dados revelam que as características da alternância de línguas pelo adulto e pela criança parecem ter semelhanças e diferenças. O sujeito adulto parece ter feito um uso da alternância mais preocupado com o curso da interação. A criança, por sua vez, não parece tê-la usado com propósitos pragmáticos específicos. Quanto à extensão das alternâncias, pode-se perceber que tanto a criança quanto o adulto utilizaram enunciados maiores do que uma única palavra isolada. O papel dos interlocutores parece ter sido decisivo nas interações aqui investigadas – especialmente nas do adulto, já que a criança ainda está em processo de tomada de consciência do papel do interlocutor na interação.

We present a very simple concrete model to demonstrate the concept of phases of an illuminated body. The main objective of our model is to help the understanding of the Moon phases as viewed from the perspective of an observer on Earth. The material allows the visualization of two important effects: (1st) even though all the time half Moon is illuminated by the Sun, we see different fractions of the illuminated Moon surface, depending on our angle of sight; (2nd) the orientation of the convex part of the Moon in the crescent and waning phases on the sky also depends on our perspective from Earth. The use of a closed box allows one to see the contrast among the different phases with no need of a dark room. We also present a text on the Moon phases, emphasizing the dependence of the aspect of the bright part on the angle of sight. En este trabajo proponemos la construcción de material didáctico de bajo costo para demostración del concepto de fases de un cuerpo iluminado. El principal objetivo de nuestro material es facilitar la comprensión de las fases de la Luna desde la perspectiva de un observador en la Tierra. El material ayuda la visualización de dos efectos importantes: (1º) a pesar de tener siempre la mitad de la Luna (representada por una bolita de espuma plástica o de ping-pong), iluminada por el Sol ( representado por una fuente de luz natural o artificial), vemos diferentes fracciones de su superficie iluminada, dependiendo del ángulo por el cual la vemos; (2º) la orientación del borde convexo de la Luna en las fases Creciente y Menguante también depende de la perspectiva por la cual la miramos desde la Tierra. El uso de una caja cerrada permite observar el contraste entre las diferentes fases sin necesidad de estar en un recinto oscuro. Presentamos también un texto explicativo sobre las fases de la Luna, enfatizando la dependencia de la apariencia de la parte iluminada con el ángulo de visión. Neste trabalho propomos a construção de material didático de baixo custo para demonstração do conceito de fases de um corpo iluminado.

This essay is on the writings of sanitary doctor Geraldo Horácio de Paula Souza in Eugenia e Imigração (1928) and, after an official trip to the Orient, in Digressões sobre a medicina chinesa clássica (1942) and A sabedoria chinesa diante da ciência ocidental e a Escola Médica de Pequim (1943). The documents, analyzed according to the conceptual approach of Carlo Ginzburg, indicate a change in his view of the Chinese. Trained according to the Rockefeller Foundation's model of experimental medicine, Geraldo de Paula Souza was guided in his work by scientific rigor and record imagery. In his youth he was of the opinion that the Chinese civilization was stagnated, but this view changed after his visit, when he perceived the Chinese republic's capacity to modernize.

Resumo O complexo tratamento de dissecção da aorta ainda apresenta controvérsias devido à gravidade do caso e à necessidade de individualização da terapêutica. A gravidade relaciona-se ao difícil diagnóstico pelas queixas inespecíficas e pelas graves complicações inerentes à evolução da doença (ruptura aórtica, síndrome de má perfusão, dissecção retrógrada, dor ou hipertensão refratária). Este relato apresenta um homem de 61 anos, tabagista e hipertenso mal controlado, que evoluiu para dissecção aórtica de tipo B de Stanford. Foi abordado através de técnica endovascular com uso de endoprótese com stent para tratamento do caso após falha do tratamento medicamentoso. O tratamento endovascular mostrou-se uma ferramenta eficaz para o tratamento definitivo, com boa taxa de sobrevida ao final do primeiro ano após o procedimento.

To compare the incidence and intensity of acute adverse effects and the variation in the temperature of facial skin by thermography after the use of noninvasive ventilation (NIV). We included 20 healthy volunteers receiving NIV via oronasal mask for 1 h. The volunteers were randomly divided into two groups according to the ventilatory mode: bilevel positive airway pressure (BiPAP) or continuous positive airway pressure (CPAP). Facial thermography was performed in order to determine the temperature of the face where it was in contact with the mask and of the nasal dorsum at various time points. After removal of the mask, the volunteers completed a questionnaire about adverse effects of NIV. The incidence and intensity of acute adverse effects were higher in the individuals receiving BiPAP than in those receiving CPAP (16.1% vs. 5.6%). Thermographic analysis showed a significant cooling of the facial skin in the two regions of interest immediately after removal of the mask. The more intense acute adverse effects occurred predominantly among the participants in whom the decrease in the mean temperature of the nasal dorsum was lower (14.4% vs. 7.2%). The thermographic visual analysis of the zones of cooling and heating on the face identified areas of hypoperfusion or reactive hyperemia. The use of BiPAP mode was associated with a higher incidence and intensity of NIV-related acute adverse effects. There was an association between acute adverse effects and less cooling of the nasal dorsum immediately after removal of the mask. Cutaneous thermography can be an additional tool to detect adverse effects that the use of NIV has on facial skin. Comparar a incidência e a intensidade de efeitos adversos agudos e a variação da temperatura da pele da face através da termografia após a aplicação de ventilação não invasiva (VNI). Foram incluídos 20 voluntários sadios, de ambos os gêneros, submetidos à VNI com máscara oronasal por 1 h e divididos aleatoriamente em dois grupos de acordo com o modo ventilatório: bilevel positive airway pressure (BiPAP) ou continuous positive airway pressure (CPAP). A termografia da face foi realizada para determinar a temperatura na região de contato da máscara e no dorso do nariz em momentos diferentes. Os voluntários preencheram um questionário de efeitos adversos após a retirada da VNI. A incidência e a intensidade dos efeitos adversos agudos foram maiores naqueles submetidos a BiPAP em relação aos submetidos a CPAP (16,1% vs. 5,6%). A análise termográfica evidenciou um esfriamento significativo da pele facial nas duas regiões de estudo imediatamente após a retirada da máscara. Os efeitos adversos agudos em maior intensidade ocorreram predominantemente no grupo de participantes cuja redução da temperatura média no dorso do nariz foi menor (14,4% vs. 7,2%). A análise visual termográfica de zonas de esfriamento e aquecimento na face identificou regiões de hipoperfusão ou hiperemia reativa. O uso do modo BiPAP associou-se a maior incidência e intensidade de efeitos adversos agudos associados à VNI. Houve associação entre efeitos adversos agudos e menor esfriamento da pele do dorso do nariz imediatamente após a retirada da máscara. A termografia cutânea pode ser uma ferramenta adicional na detecção de efeitos adversos na pele da face associados ao uso da VNI.

To develop a proposal for metrics for protocols and other technical products to be applied in assessing the Postgraduate Programs of Medicine III - Capes. The 2013 area documents of all the 48 Capes areas were read. From the analysis of the criteria used by the areas at the 2013's Triennal Assessment, a proposal for metrics for protocols and other technical products was developed to be applied in assessing the Postgraduate Programs of Medicine III. This proposal was based on the criteria of Biological Sciences I and Interdisciplinary areas. Only seven areas have described a scoring system for technical products. The products considered and the scoring varied widely. Due to the wide range of different technical products which could be considered relevant, and that would not be punctuated if they were not previously specified, it was developed, for the Medicine III, a proposal for metrics in which five specific criteria to be analyzed: Demand, Relevance/Impact, Scope, Complexity and Adherence to the Program. Based on these criteria, each product can receive 10 to 100 points. This proposal can be applied to the item Intellectual Production of the evaluation form, in subsection "Technical production, patents and other relevant production". The program will be scored as Very Good when it reaches mean ≥150 points/permanent professor/quadrennium; Good, mean between 100 and 149 points; Regular, mean between 60 and 99 points; Weak mean between 30 and 59 points; Insufficient, up to 29 points/permanent professor/quadrennium. Desenvolver proposta de métricas para protocolos e outras produções técnicas a serem aplicadas na avaliação dos Programas de Pós-Graduação da Área Medicina III da Capes. Foram lidos os documentos de área de 2013 de todas as 48 Áreas da Capes. A partir da análise dos critérios utilizados por elas na avaliação trienal 2013, foi desenvolvida uma proposta de métricas para protocolos e outras produções técnicas. Esta proposta foi baseada nos critérios adotados pelas Áreas Ciências Biológicas I e Interdisciplinar. Apenas sete áreas descreveram sistema de pontuação para produtos técnicos, e as produções consideradas e a pontuação variaram amplamente. Dada à imensa gama de produções técnicas diferentes que podem ser consideradas relevantes, e que não seriam contempladas em sistema de pontuação caso fossem especificadas, foi desenvolvida para a Medicina III uma proposta de métricas em que são analisados cinco critérios específicos para cada produção: Demanda, Relevância/Impacto, Abrangência, Complexidade e Aderência ao Programa. Com base nestes critérios, cada produção pode receber de 10 a 100 pontos. Esta proposta poderá ser aplicada ao item Produção Intelectual da Ficha de Avaliação, subitem "Produção técnica, patentes e outras produções consideradas relevantes". Será considerado Muito Bom o Programa que obtiver média ≥150 pontos/docente permanente/quadriênio; Bom, média entre 100 e 149 pontos; Regular, média entre 60 e 99 pontos; Fraco, média entre 30 e 59 pontos; e Deficiente média ≤29 pontos/docente permanente/quadriênio.

To analyze if characteristics of managers, schools, and curriculum are associated with the implementation of programs for drug abuse prevention in elementary and high schools. Cross-sectional study, with random sample of 263 school managers. Data were collected between 2012 and 2013 by a program that sends forms via internet. A closed self-filling questionnaire was applied online. Statistical analysis included Chi-square tests and logistic regression models. The outcome variable was the presence of program for drug abuse prevention inserted in the daily life and educational program of the school. The explanatory variables were divided into: demographic data of the manager; characteristics of the school and of the curriculum; health education; and drug use in the school. We found that 42.5% (95%CI 36.1-49.1) of the evaluated schools had programs for drug abuse prevention. With the multiple logistic regression model, we observed that the more time the manager has worked with education, the chance of the school having a program increased at about 4.0%. Experimenting with innovative teaching techniques also increased at about six times the chance of the school developing a program for drug abuse prevention. The difficulties in the implementation of the programs were more present in state and municipal schools, when compared with private schools, due to, for instance: lack of teaching materials, lack of money, and competing demands for teaching other subjects. The implementation of programs for drug abuse prevention in the city of Sao Paulo is associated with the experience of the manager in education and with the teaching strategies of the school. Analisar se características dos dirigentes, das escolas e do currículo escolar estão associadas à implantação de programas de prevenção ao uso de drogas nas escolas do ciclo fundamental II e médio. Estudo transversal, com amostra aleatória sistemática de 263 dirigentes escolares. Os dados foram coletados nos anos de 2012 e 2013 por meio de um programa de envio de formulários pela internet. Aplicou-se questionário fechado, de autopreenchimento on-line. A análise estatística incluiu testes Qui-quadrado e modelos de regressão logística. A variável desfecho foi a presença de programa de prevenção ao uso de drogas inserido no cotidiano e no programa pedagógico da escola. As variáveis explicativas foram divididas em: dados demográficos do dirigente; características da escola e do currículo; educação em saúde; e consumo de drogas na escola. Constatou-se que 42,5% (IC95% 36,1-49,1) das escolas avaliadas possuíam programa de prevenção ao uso de drogas. Com o modelo de regressão logística múltipla, observou-se que, a cada ano de atuação do dirigente na educação, a chance de a escola ter um programa aumentava em aproximadamente 4,0%. O fato de experimentar técnicas de ensino inovadoras também aumentou em cerca de seis vezes a chance de a escola desenvolver um programa de prevenção ao uso de drogas. As dificuldades na implantação dos programas foram mais presentes nas redes estadual e municipal, quando comparadas à rede privada, destacando-se: a falta de material didático, a falta de dinheiro e as demandas concorrentes para ensino de outras disciplinas. A implantação de programas de prevenção ao uso de drogas no município de São Paulo está associada à experiência do dirigente escolar na educação e nas estratégias de ensino da escola.

To analyze the prevalence of medicine use by the Brazilian population and its distribution according to sociodemographic factors. Study using data from the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a nationwide household survey of a representative sample of the Brazilian urban population. The data were collected between September 2013 and February 2014. The overall use of medicines, defined as the use of any medicine, use of medicines for treating chronic medical conditions and for acute health conditions, was evaluated. The independent variables included gender, age group, socioeconomic position, and region of Brazil. Analyzes included prevalence calculations, 95% confidence intervals (95%CI) and Pearson Chi-square tests to evaluate the differences between groups, considering a 5% level of significance. The prevalence of medicines use was 50.7% (95%CI 49.3-52.2), with 39.3% (95%CI 37.5-41.1) accounting for men and 61.0% (95%CI 59.3-62.6) for women. Medicines use was observed to increase with increasing age, except among children within the zero to four years age group. The lowest prevalence for medicines use was found among those with a low socioeconomic position and those who reside in the North region of Brazil. The prevalence of medicine use to treat chronic diseases was 24.3% (95%CI 23.3-25.4), whereas it was 33.7% (95%CI 32.1-35.4) for treating acute diseases. We found extensive variability in the prevalence of medicines use across regions of Brazil. The poorest regions (North, Northeast, and Midwest) have a lower prevalence of medicines use to treat chronic diseases, indicating the need to minimize inequalities in access to medicines within the country. Analisar a prevalência do uso de medicamentos pela população brasileira e sua distribuição segundo aspectos sociodemográficos. Estudo com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), pesquisa nacional de base populacional, realizada entre setembro de 2013 e fevereiro de 2014 em residências de municípios urbanos. Avaliou-se o uso de todos os medicamentos (global), uso de medicamentos para doenças crônicas e uso de medicamentos para doenças agudas. As variáveis independentes utilizadas foram sexo, idade, classificação econômica e região do País. Foram calculados prevalências e intervalos de confiança de 95% (IC95%) e aplicado teste Qui-quadrado de Pearson para avaliação das diferenças entre os grupos, considerando o nível de significância de 5%. A prevalência global de uso de medicamentos foi de 50,7% (IC95% 49,3-52,2), sendo 39,3% (IC95% 37,5-41,1) no sexo masculino e 61,0% (IC95% 59,3-62,6) no sexo feminino. Observou-se aumento nas prevalências de uso com a idade (exceto de zero a quatro anos). As menores prevalências de uso ocorreram no grupo mais pobre e na região Norte do País. A prevalência de uso de medicamentos para doenças crônicas foi de 24,3% (IC95% 23,3-25,4) e para doenças agudas foi de 33,7% (IC95% 32,1-35,4). Existe grande variabilidade nas prevalências globais de uso de medicamentos por regiões brasileiras. As regiões consideradas mais pobres (Norte, Nordeste e Centro-Oeste) apresentam menores prevalências de uso de medicamentos para doenças crônicas, o que indica a necessidade de minimizar as desigualdades no acesso aos medicamentos dentro do País.

Use of tranexamic acid (TXA) in trauma has been the subject of growing interest by researchers and health professionals. However, there are still several open questions regarding its use. In some aspects medical literature is controversial. The points of disagreement among experts include questions such as: Which patients should receive TXA in trauma? Should treatment be performed in the pre-hospital environment? Is there any need for laboratory parameters before starting TXA treatment? What is the drug safety profile? The main issue on which there is still no basis in literature is: What is the indication for treatment within massive transfusion protocols? Answer the questions proposed based on critical evaluation of the evidence gathered so far and carry out a study of cost-effectiveness of TXA use in trauma adapted to the Brazilian reality. A literature review was performed through searching Pubmed.com, Embase and Cab Abstract by headings "tranexamic AND trauma", in all languages, yielding 426 articles. Manuscripts reporting on TXA utilization for elective procedures were excluded, remaining 79 articles. Fifty-five articles were selected, and critically evaluated in order to answer study questions. The evaluation of cost effectiveness was performed using CRASH-2 trial data and Brazilian official population data. TXA is effective and efficient, and should be administered to a wide range of patients, including those with indication evaluated in research protocols and current indication criteria for TXA should be expanded. As for the cost-effectiveness, the TXA proved to be cost-effective with an average cost of R$ 61.35 (currently US$16) per year of life saved. The use of TXA in trauma setting seems to be effective, efficient and cost-effective in the various groups of polytrauma patients. Its use in massive transfusion protocols should be the subject of further investigations. O uso do ácido tranexâmico (TXA) no trauma tem sido alvo de interesse crescente por parte de pesquisadores e profissionais de saúde. No entanto, seus benefícios ainda não foram completamente definidos. Os pontos de divergência entre especialistas incluem questões como: quais pacientes devem receber TXA no trauma? O tratamento deve ser realizado em ambiente pré-hospitalar? Há necessidade de exames laboratoriais para indicar o tratamento? Qual o perfil de segurança da droga? A principal questão para a qual ainda não existe qualquer embasamento na literatura é: qual a indicação do tratamento dentro de protocolos de transfusão maciça? Responder às questões propostas, com base em avaliação crítica da evidência reunida até o momento e realizar estudo de custo-efetividade do uso do TXA no trauma adaptado à realidade brasileira. Foi realizada revisão da literatura através de estratégia de busca: PubMed.com, Embase e no Cab Abstract pelos descritores "tranexamic AND trauma", em todos idiomas, resultando em 426 artigos. Foram excluídos aqueles relativos às operações eletivas, restando 79 artigos. Cinquenta e cinco foram selecionados e avaliados criticamente com vistas a responder às questões em estudo. A avaliação de custo-efetividade foi realizada utilizando dados do estudo CRASH-2 e populacionais oficiais brasileiros. Através da análise da evidência disponível chegou-se à conclusão de que o ácido tranexâmico é tratamento eficaz e efetivo, devendo ser administrado à ampla gama de pacientes, incluindo todos aqueles com indicação já avaliada nos protocolos de pesquisa publicados e provavelmente devam-se expandir os critérios de indicação. Quanto à avaliação de custo-efetividade, o TXA mostrou-se bastante custo-eficaz com gasto médio de R$ 61,35 por ano de vida salvo. O uso do ácido tranexâmico no trauma parece ser eficaz, efetivo e custo-eficaz nos diversos grupos de pacientes politraumatizados. Seu uso em protocolos de transfusão maciça ainda deve ser objeto de futuras investigações.

Barreto, Maria Renilda Nery

2008-01-01

This paper presents the traditions of assisted childbirth in the Brazilian state of Bahia in the 19th Century and develops the hypothesis that two obstetrical traditions coexisted in the capital, Salvador, namely the doctor-midwives--who used technical resources and knowledge acquired from obstetrics as a medical specialty--and the traditional midwives, whose know-how was purely of an empirical-sensorial nature. Despite all efforts employed by the doctors to win over the confidence of Bahian families, the midwives continued to be predominant in the art of 'delivering' children and treating female illnesses. The analysis focuses on the social and professional segments that were active in assisted birth; the role of the Bahian College of Medicine (Faculdade de Medicina da Bahia) in the training and certification of midwives and the use of newspapers as a way to legitimize the doctor-midwives; it also discusses the scant coverage of the midwives in these media.

To assess the prevalence of smoking and associated variables in female sex workers (FSWs). This was a quantitative cross-sectional study involving FSWs in the city of Botucatu, Brazil, who completed a sociodemographic questionnaire, including data regarding smoking status, motivational stage of change, and degree of nicotine dependence, as well as the Perceived Stress Scale and the Hospital Anxiety and Depression Scale. We included 83 FSWs. The mean age was 26.8 years. Among the participants, 58 (69.8%) had at least a high school education, only 26 (31.3%) resided in the city of Botucatu, 59 (71.1%) were smokers, 5 (6.0%) were former smokers, 74 (89.2%) regularly consumed alcohol, and 43 (51.8%) used illicit drugs. The majority of the women were classified as having an intermediate stress level, and 51 (61.4%) were classified as having possible or probable anxiety, whereas depression was found to be improbable in 57 (68.7%). The level of nicotine dependence was high among the smokers, the majority of whom showed no intention to quit smoking. Smoking was associated with illicit drug use (p = 0.0271) and with alcohol consumption (p = 0.0001), although not with the levels of stress, anxiety, or depression; nor was the age at smoking initiation associated with the length of time as an FSW (p = 0.4651). The prevalence of smoking among the FSWs evaluated here was much higher than the 8.3% reported for the overall female population of Brazil. Our findings show that FSWs are exposed to various risk factors inherent to their profession. Therefore, harm reduction is an important strategy to be adopted. Avaliar a prevalência de tabagismo e variáveis associadas em mulheres profissionais do sexo (MPS). Estudo de corte transversal quantitativo com MPS na cidade de Botucatu (SP), as quais completaram um questionário sociodemográfico, incluindo informações sobre tabagismo, estágio motivacional para cessação do tabagismo e grau de dependência da nicotina, assim como a Escala de Estresse Percebido e a Escala Hospitalar de Ansiedade e Depressão. Foram incluídas 83 MPS. A média de idade foi de 26,8 anos. Entre as participantes, 58 (69,8%) possuíam pelo menos o ensino médio, apenas 26 (31,3%) residiam em Botucatu, 59 (71,1%) eram fumantes, 5 (6,0%) eram ex-fumantes, 74 (89,2%) faziam uso de bebidas alcoólicas e 43 (51,8%) faziam uso de algum tipo de drogas. A maioria foi classificada com grau de estresse médio, 51 (61,4%) apresentaram nível de ansiedade possível ou provável, e 57 (68,7%) tiveram resultado improvável para depressão. O nível de dependência da nicotina foi elevado entre as fumantes. Dessas, a maioria não tinha intenção de parar de fumar. Houve associações do tabagismo com o consumo de drogas ilícitas (p = 0,0271) e com o uso de bebidas alcoólicas (p < 0,0001); porém, não houve associações do tabagismo com as questões de humor e nem da idade da iniciação tabágica com o tempo que trabalhavam como MPS (p = 0,4651). A prevalência de tabagismo entre as MPS estudadas se mostrou muito elevada quando comparada à da média nacional de mulheres (8,3%). Evidenciou-se que MPS estão expostas a diversos fatores de risco inerentes da própria profissão, sendo a redução de danos uma estratégia importante a ser trabalhada.

Nonostante i cambiamenti in corso nell'ambito delle pubblicazioni scientifiche (STEM - scienza, tecnologia, ingegneria e medicina), è indubbio che i direttori delle riviste restano i più importanti custodi del processo editoriale. In questo articolo vengono analizzati i motivi per cui i direttori delle riviste devono continuare ad attenersi ai principi editoriali fondamentali e a utilizzare le nuove tecnologie digitali solo per dare forza al contenuto, ma non per sostituirlo nella sua qualità. Per raggiungere questo obiettivo, in un'epoca caratterizzata da controlli ed equilibri, i direttori delle riviste devono essere attentamente sorvegliati e ritenuti responsabili tanto quanto gli autori che essi stessi valutano. Qualunque scorciatoia potrebbe avere conseguenze negative e inaspettate per quella rivista che non si attenesse a tali regole, che vedrebbe intaccata la propria reputazione e che dovrebbe faticare per recuperare la fiducia dei propri lettori. Quindi, a rischio di sembrare scontati, è meglio prevenire il danno alla reputazione piuttosto che curarlo. L'unico modo per evitarlo è che i direttori delle riviste si adattino a un crescente movimento sempre più critico, che richiede maggiore trasparenza e responsabilità da parte di chi contribuisce a costruire la base delle conoscenze scientifiche e dalla società, specialmente laddove la ricerca è finanziata pubblicamente.

To assess whether there is a preference for international journal citation to the detriment of national ones in ten Brazilian medical journals, in two different periods. All references in the articles published in Arquivos Brasileiros de Oftalmologia, Revista Brasileira de Cirurgia Cardiovascular, Revista da Associação Médica Brasileira, São Paulo Medical Journal, Arquivos Brasileiros de Endocrinologia e Metabologia, Clinics, Jornal Brasileiro de Pneumologia, Revista da Sociedade Brasileira de Medicina Tropical, Revista Brasileira de Psiquiatria e Acta Ortopédica Brasileira in the years 2011 and 2007 were analyzed, assessing the number of articles published in national and international journals. A total of 36,125 references from 1,462 articles published in the 10 aforementioned journals were analyzed. Of the total number, 4.242 (11.74%) were from Brazilian journals. There was no significant difference between the two analyzed periods. A total of 453 (30,98%) of the articles studied non-cited brazilian papers,and 81 (5.54%) articles had more Brazilian than international references. Of total references analyzed, 11.74% were related to articles published in Brazilian journals. This number, when compared to the percentage of Brazilian articles published in the medical area, demonstrates a good number of citations of national articles. Copyright © 2012 Elsevier Editora Ltda.

ABSTRACT Objective: To analyze the characteristics of patients with Lisfranc injuries and their associated fractures. Methods: This is a retrospective analysis on 42 patients with Lisfranc injuries hospitalized at Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, between 2006 and 2010. Parameters on patient profile, risk factors, fracture characteristics, data on treatment and acute complications were analyzed. Results: Analysis of 42 cases showed that in our sample, men were more affected than women, with a ratio of 4.25:1. The most frequent trauma mechanism was car accident, followed by motorcycle accident. The most frequent type of injury was isolated lesion type B of Quenu and Kuss classification, representing 50% of cases. The most common fracture on the sample was the second metatarsal bone, with 16 cases, followed by cuboid bone fracture. Among the 42 cases, 17% had exposed fractures and 33 patients presented other associated fractures. The mean time elapsed between the trauma and definitive treatment was 6.7 days, while the mean length of hospital stay was 13.8 days. Six patients presented acute postoperative complications. Conclusion: Lisfranc injuries are more common in men undergoing automobile trauma. The prevalence of associated fractures is a frequent finding and the hospital stay may be longstanding.Level of Evidence IV, Case Series. PMID:28642650

To analyze the use of health services and the quality of medical care received by Brazilian older adults with and without functional limitation. The main analyses were based on a national sample representing 23,815 participants of the National Survey on Health (PNS) aged 60 years or older. Functional limitation was defined by the difficulty to perform at least one out of ten basic or instrumental activities of daily living. Potential confounding variables included predisposing and enabling factors of the use of health services. The prevalence of functional limitation was 30.1% (95%CI 29.2-31.4). The number of doctor visits and hospitalizations in the past 12 months showed statistically significant associations with functional limitation, both for users of the public system (OR = 2.48 [95%CI 2.13-2.88] for three or more doctor visits and OR = 2.58 [95%CI 2.15-3.09] for one or more hospitalizations) and of the private system (OR = 2.56 [95%CI 1.50-4.36] and OR = 2.22 [95%CI 1.64-3.00], respectively). The propensity to use basic health units was higher among users of the private system with functional limitations (OR = 2.01 [95%CI 1.12-3.59]). Only two out of seven indicators of the quality of medical care received were associated with functional limitation, in the perception of users of public and private systems. The public system users with functional limitations did worse evaluation of the freedom for choosing the doctor and waiting time for an appointment, when compared with users of the same system without these limitations (OR = 0.81 [95%CI 0.67-0.99] and OR = 0.76 [95%CI 0.62-0.93], respectively). Older adults with functional limitations use more health services in comparison with those without such limitations. The magnitude of the association between functional limitation and number of doctor visits and hospitalizations was similar in the public and private health systems. Analisar o uso de serviços de saúde e a qualidade da atenção médica recebida por idosos brasileiros com e sem limitação funcional. As análises principais foram baseadas em amostra nacional representativa de 23.815 participantes da Pesquisa Nacional de Saúde com 60 anos ou mais. A limitação funcional foi definida pela dificuldade para realizar pelo menos uma entre dez atividades básicas ou instrumentais da vida diária. Potenciais variáveis de confusão incluíram fatores predisponentes e facilitadores do uso de serviços de saúde. A prevalência da limitação funcional foi de 30,1% (IC95% 29,2-31,4). O número de consultas médicas e a ocorrência de hospitalizações nos últimos 12 meses apresentaram associações estatisticamente significantes com a limitação funcional, tanto entre usuários do sistema público (OR = 2,48 [IC95% 2,13-2,88] para três ou mais consultas e OR = 2,58 [IC95% 2,15-3,09] para uma ou mais hospitalizações) quanto do sistema privado (OR = 2,56 [IC95% 1,50-4,36] e OR = 2,22 [IC95% 1,64-3,00], respectivamente). A propensão ao uso da unidade básica de saúde foi maior entre usuários do sistema privado com limitações funcionais (OR = 2,01 [IC95% 1,12-3,59]). Entre sete indicadores da qualidade da atenção médica recebida, na percepção dos usuários dos sistemas público e privado, somente dois apresentaram associação com a limitação funcional. Os usuários do sistema público com limitações funcionais fizeram pior avaliação da liberdade para escolha do médico e do tempo de espera para a consulta, em comparação aos usuários do mesmo sistema sem essas limitações (OR = 0,81 [IC95% 0,67-0,99] e OR = 0,76 [IC95% 0,62-0,93], respectivamente). Idosos com limitações funcionais utilizam mais serviços de saúde em comparação aos seus pares sem essas limitações. A magnitude da associação entre a limitação funcional e o número de consultas médicas e de hospitalizações foi semelhante nos sistemas público e privado de saúde.

The Acquired Immunodeficiency Syndrome (AIDS) constitutes a sub-epidemic in Brazil. Due to the increasing number of women infected by the virus, the vertical transmission increased substantially, and due to the lack of adequate prophylactic treatment, many children are infected and show manifestations of the disease in early ages. Multiple systems are affected by the HIV virus, and the skin is often the first organ to be involved. The objective of this study is to analyze the clinic, dermatological and epidemiological profiles of children carriers of the virus in the City of Manaus aiming at identifying the most frequent dermatoses that affect these children and try to relate these dermatoses to the immunologic deterioration. A study was conducted where children carriers of the HIV virus from the Fundação Alfredo da Matta and Fundação de Medicina Tropical were studied from March 2007 to July 2008. These children were submitted to dermatological and laboratorial exams such as viral load dosage and CD4+ and CD8+ counts. During the study period, 70 HIV + children were examined; all of them had AIDS and had been contaminated by vertical transmission. The average number of dermatoses by children was 1.73, and 95.5% had at least one dermatosis during the study period. The most frequent manifestations were atopic dermatitis (22.9%), childhood prurigo (20%) and warts (18,6%). Children with HIV/AIDS have more skin disorders than children without HIV/AIDS. There was no statistical difference between the children in the group using ARVT and the group that wasn't using it.

A redução do custo de combustível de uma manobra é atualmente a grande prioridade de todos os programas espaciais existentes no mundo. As manobras assistidas pela gravidade são uma ótima forma de se contornar o problema pois proporcionam economias com vasto impacto no custo final da missão. Neste trabalho é feito um estudo particular do controle orbital de um satélite artificial da Terra usando a gravidade da Lua. O objetivo é estudar uma técnica econômica para uma mudança de plano de um satélite que está em órbita em volta da Terra. A idéia principal desta abordagem é enviar primeiramente o veículo espacial em direção à Lua usando uma manobra mono-impulsiva para que assim o campo gravitacional da Lua possa fazer a mudança de plano desejada (sem custo de combustível) e só então retornar o veículo aos valores iniciais de semi-eixo e excentricidade usando uma manobra bi-impulsiva tipo Hohmann. Para tanto, é assumido que a espaçonave inicia em uma órbita circular coplanar à órbita da lua em torno da Terra e a meta é colocá-la em uma órbita similar que difere da órbita inicial somente pela inclinação. São usadas equações analíticas baseadas na abordagem Patched Conics para se calcular a variação na velocidade, momento angular, energia e inclinação do veículo espacial que realiza esta manobra. Várias simulações são feitas para se avaliar as economias de combustível envolvidas.

Meningococco B: controllo di due focolai epidemici mediante vaccinazione

PubMed Central

2014-01-01

Riassunto La problematica di un efficace approccio vaccinale nei confronti del Meningococco B (MenB) è stata superata identificando con la metodica della "reverse vaccinology" alcuni antigeni capaci di indurre una risposta verso la maggior parte dei ceppi di MenB circolanti nel mondo. Il nuovo vaccino MenB a 4 componenti (4CMenB) è stato autorizzato in Europa, Australia e Canada, ed è entrato nei calendari di immunizzazione pediatrica internazionali: Australia, Canada, UK. In Italia, le prime regioni che hanno raccomandato la vaccinazione contro il MenB sono state Basilicata e Puglia. La gestione di epidemie/focolai epidemici richiede la messa in atto di una risposta rapida da parte delle autorità sanitarie nei confronti di una emergenza sanitaria ad elevato impatto, anche emotivo, sulla popolazione, come recentemente dimostrato in due università americane. Alla dichiarazione di focolaio epidemico in atto, in entrambi i contesti si è attivata una procedura per l'uso del vaccino 4CMenB non ancora autorizzato negli USA. È stato così possibile organizzare gli interventi di profilassi attiva nei due campus universitari, adottando il primo impiego su larga scala del nuovo vaccino 4CMenB e conseguendo, in tempi relativamente brevi, elevati tassi di copertura vaccinale. A fronte di circa 14000 studenti immunizzati con almeno una dose, non è stata segnalata alcuna problematica di eventi avversi conseguenti all'immunizzazione; ad oggi non si sono verificati casi nei soggetti che hanno ricevuto il vaccino. Come conseguenza dei due focolai descritti, è oggi in corso la valutazione da parte dell'FDA per l'estensione dell'uso del vaccino 4CMenB negli Stati Uniti negli adolescenti e giovani adulti.

2016-08-22

The main proposal to set up an articulated mode of operation of health services has been the concept of network, which has been appropriated in different ways in the field of public health, as it is used in other disciplinary fields or even taking it from common sense. Amid the diversity of uses and concepts, we recognize the need for rigorous conceptual demarcation about networks in the field of health. Such concern aims to preserve the strategic potential of this concept in the research and planning in the field, overcoming uncertainties and distortions still observed in its discourse-analytic circulation in public health. To this end, we will introduce the current uses of network in different disciplinary fields, emphasizing dialogues with the field of public health. With this, we intend to stimulate discussions about the development of empirical dimensions and analytical models that may allow us to understand the processes produced within and around health networks. RESUMO A principal proposta para configurar um modo articulado de funcionamento dos serviços de saúde tem sido o conceito de rede, que vem sendo apropriado de diferentes formas no campo da saúde coletiva, conforme seu emprego em outros campos disciplinares ou mesmo tomando-o do senso comum. Em meio à pluralidade de usos e concepções, reconhecemos a necessidade de rigorosa demarcação conceitual acerca de redes no campo da saúde. Tal preocupação visa a preservar o potencial estratégico desse conceito na investigação e planificação no campo, superando precariedades e distorções ainda observadas em sua circulação discursivo-analítica na saúde coletiva. Para tanto, apresentaremos os usos correntes de rede em diferentes campos disciplinares, destacando interlocuções com o campo da saúde coletiva. Com isso, pretendemos estimular o debate acerca do desenvolvimento de dimensões empíricas e modelos de análise que permitam compreender os processos produzidos no interior e ao redor das redes de saúde.

In the last few years, new primary immunodeficiencies and genetic defects have been described. Recently, immunoglobulin products with improved compositions and for subcutaneous use have become available in Brazil. In order to guide physicians on the use of human immunoglobulin to treat primary immunodeficiencies, based on a narrative literature review and their professional experience, the members of the Primary Immunodeficiency Group of the Brazilian Society of Allergy and Immunology prepared an updated document of the 1st Brazilian Consensus, published in 2010. The document presents new knowledge about the indications and efficacy of immunoglobulin therapy in primary immunodeficiencies, relevant production-related aspects, mode of use (routes of administration, pharmacokinetics, doses and intervals), adverse events (major, prevention, treatment and reporting), patient monitoring, presentations available and how to have access to this therapeutic resource in Brazil. RESUMO Nos últimos anos, novas imunodeficiências primárias e defeitos genéticos têm sido descritos. Recentemente, produtos de imunoglobulina, com aprimoramento em sua composição e para uso por via subcutânea, tornaram-se disponíveis em nosso meio. Com o objetivo de orientar o médico no uso da imunoglobulina humana para o tratamento das imunodeficiências primárias, os membros do Grupo de Assessoria em Imunodeficiências da Associação Brasileira de Alergia e Imunologia produziram um documento que teve por base uma revisão narrativa da literatura e sua experiência profissional, atualizando o I Consenso Brasileiro publicado em 2010. Apresentam-se novos conhecimentos sobre indicações e eficácia do tratamento com imunoglobulina nas imunodeficiências primárias, aspectos relevantes sobre a produção, forma de utilização (vias de administração, farmacocinética, doses e intervalos), efeitos adversos (principais efeitos, prevenção, tratamento e notificação), monitorização do paciente, apresentações disponíveis e forma de obtenção deste recurso terapêutico em nosso meio.

L'INAF-OA Cagliari (OACa) sta sviluppando un ricevitore criogenico a basso rumore basato su un mixer SSB (Single Side Band) a superconduttore SIS (Superconductor-Insulator-Superconductor) per la banda 3 mm. Il ricevitore, acquistato da IRAM, è stato fortemente modificato per essere adattato al fuoco Gregoriano di SRT (Sardinia Radio Telescope). Lo strumento è caratterizzato da una nuova criogenia a ciclo chiuso 4 K (per evitare l'uso di elio liquido in antenna), da un nuovo oscillatore locale (di tipo ALMA Banda 3) e da un nuovo sistema di controllo e di monitoraggio basato su schede Raspberry ed Arduino sviluppato ad OACa. Verranno presentati i recenti sviluppi sul ricevitore, inclusi i risultati preliminari della misura della temperatura di rumore, che raggiunge un valore pari a Trec=66 K alla frequenza di 86 GHz, nonostante la criogenia non sia ancora ottimizzata. L'INAF-OACa è coinvolto nel progetto AETHRA (Advanced European Technologies for Heterodyne Receivers for Astronomy) nel quadro del programma Radionet/Horizon2020 per il quale sta contribuendo al WP1 (Work Package 1). Lo scopo del WP1 è di sviluppare e costruire un dimostratore di un array di ricevitori a doppia polarizzazione per la banda 3 mm basato su amplificatori criogenici a basso rumore (LNA) in tecnologia a semiconduttore MMIC. Nell'ambito del WP1 l'OACa ha in carico il progetto di un OrthomodeTransducer (OMT) in guida d'onda o in tecnologia planare per la banda 72-116 GHz che sia integrabile con amplificatori MMICs ed adatto all'integrazione in un array da installare nel piano focale di un radiotelescopio. Verranno presentati i design preliminari degli OMT per AETHRA, che sono basati su prototipi sviluppati in passato da OACa.

Balan, Catalin

Na ultima decada, foram feitos grandes progressos no desenvolvimento dos detetores de detecao direta das particulas que constituem a materia negra. Com estrategias do aumento gradual do volume do alvo e, simultaneamente, de reducao dos niveis de fundo, a experiencia XENON obteve resultados muito bons e perspetivas promissoras para a detecao de materia negra. Tarefas relativas a analise de dados experimentais adquiridos com o detetor de dupla fase em uso, assim como as simulacoes do campo eletrico, desenvolvimento, montagem e testes para o proximo detetor XENON1T, assim como a participacao regular na manutencao geral e monitorizacao do prototipo atual XENON100 no LNGS, constituiram o plano de trabalhos para as atividades de investigacao do presente doutoramento e a minha contribuicao para a otimizacao da detecao de cintilacao nos detetores da experiencia XENON. A necessidade de alcancar niveis elevados de sensibilidade, requer inovacao em todos os aspetos fisicos do detetor, assim como a reducao de todas as fontes de radioatividade que contribuem para o fundo. O modo mais indicado de operacao para os detetores com enchimento a Xe no estado liquido e gasoso envolve a medicao da cintilacao primaria e da secundaria provenientes da interacao das particulas no Xe liquido. A razao entre estes dois sinais permite diferenciar claramente a maior parte dos eventos correspondentes as fundo dos eventos correspondentes a WIMPs. Deste modo, a leitura dos sinais correspondentes a cintilacao e de extrema importancia. A amplitude do sinal de cintilacao antes dos fotossensores e maximizada atraves da otimizacao de varios parametros, tais como a geometria do alvo do detetor, a transparencia das grelhas dos eletrodos, a uniformidade do ganho em cintilacao secundaria e a utilizacao de material reflectivo para cobrir as superficies que nao sao fotossensiveis.

Brites, Carlos Antonio Delgado Sousa

Na ultima decada emergiu uma linha de investigacao muito activa em termometros nao invasivos e precisos que possam determinar temperatura a escala nanometrica. Esta investigacao foi fortemente estimulada pelas numerosas solicitacoes da nanotecnologia e da biomedicina, por exemplo. Uma das abordagens mais promissoras propoe o uso de ioes trivalentes de lantanideos que apresenta propriedades fotoluminescentes que dependem da temperatura. Neste trabalho demonstra-se que esta tecnica combina as vantagens de te um limite de deteccao de 0.5 graus com sensibilidade ate 4.5 % K-1. Este termometro molecular pode ser processado em filmes finos ou nanoparticulas, abrindo os campos de aplicacao a diferentes utilizacoes. As nanoparticulas de silica produzidas sao caracterizadas na presenca e na ausencia de ioes lantanideos. Sem o metal, as nanoparticulas de APTES/TEOS demonstram ser luminescentes sob excitacao UV sem necessidade de utilizar qualquer tratamento termico. O rendimento quantico de emissao depende apenas da proporcao dos silanos e pode atingir o valor de 0.15 +/- 0.02. A co-dopagem destas nanoparticulas com Eu3+ e Tb3+ permite obter sondas com resposta raciometrica, com a possibilidade de ajustar a gama de temperaturas de operacao e a sensibilidade, via desenho inteligente da matriz de suporte e dos ligandos de beta-dicetona que estao coordenados ao iao metalico. Quando processados como filmes, este termometro permite o mapeamento de temperaturas com resolucao espacial 1.8 mum. A racionalizacao da dependencia de temperatura e uma ferramenta util para desenvolver termometros que operam em gamas de temperatura especificos (e.g. gama de temperatura fisiologica, 290-340 K) com sensibilidade acima de 0.5 % K-1. A combinacao de esforcos de um grande numero de diversas disciplinas ira previsivelmente permitir o surgimento de termometros moleculares novos e sofisticados, preenchendo os principais requisitos das nanociencias.

THE FASCICULUS MEDICINA, printed in 1491, is considered the first illustrated medical book. The Latin essays and illustrations in this volume provide insight into the medical knowledge of Western Europe and, in the Italian edition published in 1493, glimpses into the medical culture of the late 15th century. We outline the scientific and social environments into which the Fasciculus Medicinae of 1491 was introduced and the transition that occurred with the publication of the 1493 Italian edition. The artist of the 1493 Fasciculo witnessed a paradigm shift occurring. In four woodcuts, the artist captured four themes: the relevance of knowledge-based medicine, the emergence of laboratory medicine, the Hippocratic lessons of patient observation, and the emerging revolution in anatomy.

Ixodes schulzei Aragão & Fonseca, 1951 is a tick endemic to Brazil, where nine species of Ixodes Latreille, 1796 are currently known to occur. Larvae, nymphs and females of I. schulzei were obtained from a laboratory colony originating from an engorged female collected on a free-living water rat Nectomys squamipes from the Santa Branca municipality, São Paulo State. Only female ticks were obtained from engorged nymphs. Unfed immature and female adult specimens were measured and the descriptions were based on optical and scanning electron microscopy, as were drawings of some features of the larva. Both immature stages present the very long palpi and basis capituli, and the female has large, contiguous porose areas. However, the basis capituli is triangular, with a slight central elevation in the larva and nymph, whereas in the female this area is depressed. The I. schulzei types deposited at the FIOCRUZ (Instituto Oswaldo Cruz) were also examined, as was other material from collections, such as the IBSP (Coleção Acarológica do Instituto Butantan), CNC-FMVZ/USP (Coleção Nacional de Carrapatos da Faculdade de Medicina Veterinária e Zootecnia da USP) and USNTC (United States National Tick Collection). In addition, the relationship between I. schulzei and other immature neotropical species of Ixodes is discussed.

Epidemiological data about the treatment of patients with end-stage renal disease in the Great Sao Paulo, Brazil, are presented. Patients on dialysis in the city of Sao Paulo and surroundings, distributed in 15 Regional Offices of Health (ERSAs), during 1991, were studied. Data were collected by the Secretary of Health of the State of Sao Paulo. There was an increase of 18.6% in the number of alive patients on dialysis from January 1 to December 31 (n = 2,425 to 2,875). Patients were treated in 40 dialysis centers, of which 24 were located in the ERSAs 1, 2 and 3. Depending on the ERSA, a percentage of patients varying from 37% to 88% did not live in the same region where they received treatment. At the end of the year, 79% of the patients were on hemodialysis, 15% on continuous ambulatory peritoneal dialysis and 6% on intermittent peritoneal dialysis. The diagnoses more frequently reported of primary disease were non-determined, glomerulonephritis, hypertension and diabetes (36%, 27%, 17% and 8%, respectively). New cases (1,483) initiated dialysis during the year, corresponding to an incidence rate of 83 patients per million population (pmp). The prevalence of patients on dialysis was 148 pmp. The annual fatality rate was 17.2% (range in the ERSAs: 12.0-3.5). The actuarial one year survival for the patients who started treatment in 1991 was 80.2%. 246 patients received transplantation, corresponding to 14 patients pmp. Dialysis treatment provided in the Great Sao Paulo is satisfactory.(ABSTRACT TRUNCATED AT 250 WORDS)

An accurate measurement of the position and trajectory of the space debris fragments is of primary importance for the characterization of the orbital debris environment. The Medicina Radioastronomical Station is a radio observation facility that is here proposed as receiving part of a ground-based space surveillance system for detecting and tracking space debris at different orbital regions (from Low Earth Orbits up to Geostationary Earth Orbits). The proposed system consists of two bistatic radars formed by the existing Medicina receiving antennas coupled with appropriate transmitters. This paper focuses on the current features and future technical development of the receiving part of the observational setup. Outlines of possible transmitting systems will also be given together with the evaluation of the observation strategies achievable with the proposed facilities.

Hospitalizations represent an important share of healthcare, due to both the complexity of actions and the financial volume applied. This descriptive-exploratory investigation had the purpose to identify and describing the physical and financial production of hospitalizations performed in a school hospital in the state of São Paulo, from 1996 to 2003, focusing the specialties of surgical clinic, medical clinic, pediatrics and obstetrics. Data collection was performed by searching the official databanks of the studied institution. In that period, a global 8.5% reduction in the frequency of admittances and a 78.4% increase in the financial resources were observed. Surgical clinic, with more expensive procedures, increased its admittances; the production in obstetrics showed the lowest variation. The increasing incorporation of technology, the demands from regional users and the migration of users from the supplementary system to the SUS may justify the variation of production in the different specialties.

We tested indicators for evaluating occupational tuberculosis prevention programs in six hospitals. The criterion to define feasibility was the time spent to calculate the indicators. time spent to evaluate the indicators ranged from 2h 52min to 15h11min 24sec. The indicator for structure evaluation required less time; the longest time was spent on process indicators, including the observation of healthcare workers' practices in relation to the use of N95 masks. There was an hindrance to test one of the indicators for tuberculosis outcomes in five situations, due to the lack of use of tuberculin skin test in these facilities. The time requires to calculate indicators in regarding to the outcomes for occupational tuberculosis largely depends upon the level of organizational administrative structure for gathering data. indicators to evaluate the structure for occupational tuberculosis prevention are highly feasible.

2003-08-01

Atualmente, a integração de redes neurais com técnicas da Matemática Nebulosa (Fuzzy Sets), tem sido usada robustamente para fazer previsões em vários sistemas físicos. Este trabalho representa uma continuidade da contribuição apresentada anteriormente durante a XXVIIa Reunião Anual da SAB, onde exploramos a aplicação de redes neurais para previsões futuras de séries temporais. Para este, enfatizamos o uso da técnica ANFIS (Adaptative Neuro-Fuzzy Inference System), que consiste em uma rede do tipo back-propagation, onde os dados são processados em uma camada intermediária, tendo numa camada de saída, os dados numéricos. Para que a previsão seja feita com sucesso utilizando-se técnicas matemáticas adequadas, é fundamental a existência de uma série razoavelmente longa de modo que a dinâmica contida nesta possa ser melhor extraída pela rede neural. Nesse sentido, foram utilizados novamente os dados históricos das manchas do Sol (1818-2002) afim de verificar o comportamento futuro da atividade solar (Ciclos de Schawbe) a partir da técnica descrita acima. Previsões realizadas para o ciclo anterior (n.22, máximo de 158,5 em julho de 1989), bem como para o atual (n.23, máximo de 153 em setembro de 2000), apontam valores bastante coerentes com os publicados na literatura, levando em consideração, respectivamente, as barras de erros associadas: 166+/-18 e 160+/-14. Para o próximo ciclo de Schawbe (2006-2017), nossa previsão aponta o valor de 172+/-23 como máximo para o primeiro semestre de 2011 (Abril +/- 3 meses). A ANFIS acompanha de maneira satisfatória o movimento das séries estudadas durante o treinamento e durante a verificação (menor dispersão das funções de pertinência), com erro absoluto inferior a 20 por cento.

This article discusses elements of a theory of innovation from the perspective of innovation networks and social construction of technology, based on Habermas' Theory of Communicative Action and authors from the Sociology of Innovation. Based on the theoretical framework of the communicative production of scientific facts, we focus on innovation management as a basic dimension that must meet some organizational and methodological requirements in order to power its results. We present and discuss instruments such as Situational Planning, Prospective Analysis, Strategic Portfolio Management, and Networks Management that can help deal with the challenge of innovation and exploration of the future. We conclude that network organizational formats centered on reflexivity of interdisciplinary groups and planning approaches that encourage innovation criteria in assessing the attractiveness of activities and that help anticipate forms of innovation through systematic prospective analysis can potentiate the process of generating innovation as a product of networks. Resumo: No artigo são discutidos elementos de uma teoria da inovação numa perspectiva de redes de inovação e de construção social da tecnologia, a partir da Teoria do Agir Comunicativo de Habermas e de autores da Sociologia da Inovação. Com base no marco teórico da produção comunicativa de fatos científicos, focamos a gestão da inovação como uma dimensão fundamental que deve contemplar alguns requisitos, tanto de natureza organizacional quanto metodológica, para potencializar seus resultados. Apresentamos e discutimos instrumentos como o Planejamento Situacional, a Análise Prospectiva, a Gestão Estratégica de Portfólios e a Gestão de Redes que podem contribuir para o desafio da inovação e exploração do futuro. Conclui-se que formas organizativas em rede, centradas na reflexividade de grupos interdisciplinares, e enfoques de planejamento que estimulem o uso de critérios de inovação na avaliação da atratividade das atividades e que ajudem a antecipar formas de inovação por meio de uma análise prospectiva sistemática podem potencializar o processo de geração da inovação como produto de redes.

To compare the scientific methodology and quality of articles published in Anales Españoles de Pediatría and Medicina Clínica. A stratified and randomized selection of 40 original articles published in 2001 in Anales Españoles de Pediatría and Medicina Clínica was made. Methodological errors in the critical analysis of original articles (21 items), epidemiological design, sample size, statistical complexity and levels of scientific evidence in both journals were compared using the chi-squared and/or Student's t-test. No differences were found between Anales Españoles de Pediatría and Medicina Clínica in the critical evaluation of original articles (p > 0.2). In original articles published in Anales Españoles de Pediatría, the designs were of lower scientific evidence (a lower proportion of clinical trials, cohort and case-control studies) (17.5 vs 42.5 %, p 0.05), sample sizes were smaller (p 0.003) and there was less statistical complexity in the results section (p 0.03). To improve the scientific quality of Anales Españoles de Pediatría, improved study designs, larger sample sizes and greater statistical complexity are required in its articles.

Scientific communication knowledge is specifically based in the analysis of the bibliographic references inside the publications. Pattern and laws determining the information consumption in the items of the journal Medicina Clinica are investigated in the present study as its own aim. An analysis was performed on the 13,286 references downloaded from 618 papers published by the journal in 1990. With dBASE IV was generated a database for the management of the information; data was distributed in several tables through criteria of age, documentary types, countries, journals and Bradford zones. The analysed references belong to 1,241 different journals, 110 from Spain. Being two thirds of the total sum, the publications from United States and United Kingdom have received more citations than those from Spain. The publications from european countries, like France, Germany and Italy, are scarcely present. Bradford core is constituted by the journals Medicina Clinica and The Lancet. The analysis of the bibliographic references available from the articles in this journal is able to produce knowledge on the information consumption by the practitioners; its usefulness as a complementary utility to the Indice de Citas e Indicadores Bibliométricos de Revistas Españolas de Medicina Interna y sus especialidades 1990 must be considered.

To estimate the prevalence of illicit drug use and its association with binge drinking and sociodemographic factors among adolescent students. This is a cross-sectional study with probabilistic conglomerate sampling, involving 1,154 students, aged 13 to 19 years old, from the public school system, in the city of Olinda, State of Pernambuco, Brazil, carried out in 2014. We used the Youth Risk Behavior Survey questionnaire, validated for use with Brazilian adolescents. The Chi-square test (≤ 0.05) and Poisson regression analysis were used to estimate the prevalence ratios, with 95% confidence intervals. Use in life of illicit drugs was four times more prevalent among students who reported binge drinking (95%CI 3.19-5.45). Being in the age group of 16 to 19 years, being male, and having no religion were also significantly associated with illicit drug use. The prevalence of use in life of illicit drugs was higher in this study than in other studies carried out in Brazil and it was strongly associated with binge drinking. This factor was associated with gender, age, and religion.

Estudo transversal com amostra probabilística por conglomerado, envolvendo 1.154 estudantes, de 13 a 19 anos de idade, da rede pública de ensino, no município de Olinda, PE, 2014. Foi utilizado o questionário Youth Risk Behavior Survey, validado para uso com adolescentes brasileiros. Para análise dos dados foi utilizado o teste do Qui-quadrado (≤ 0,05) e análise de regressão de Poisson, para estimar razões de prevalência, com intervalos com 95% de confiança. O uso na vida de drogas ilícitas foi quatro vezes mais prevalente entre os estudantes que relataram o binge drinking (IC95% 3,19-5,45). Estar na faixa etária de 16 a 19 anos, ser do sexo masculino e não ter religião também foram significativamente associados ao uso de drogas ilícitas. A prevalência do uso de drogas ilícitas na vida foi superior a outros estudos realizados no Brasil e esteve fortemente associado ao binge drinking. Esse fator mostrou associação com gênero, idade e religião.

To assess the prevalence of the use of medicines and other products for therapeutic purposes in the Brazilian pediatric population and test whether demographic, socioeconomic and health factors are associated with use. A cross-sectional population-based study (National Survey on Access, Use and Promotion of Rational Use of Medicines - PNAUM), including 7,528 children aged 12 or younger, living in urban areas in Brazil. Medicine use to treat chronic or acute diseases was reported by the primary caregiver present at the household interview. Associations between independent variables and medicine use were investigated by Poisson regression. The overall prevalence of medicine use was 30.7% (95%CI 28.3-33.1). The prevalence of medicine use for chronic diseases was 5.6% (95%CI 4.7-6.7) and for acute conditions, 27.1% (95%CI 24.8-29.4). The factors significantly associated with overall use were five years old or under, living in the Northeast region, having health insurance and using health services in the last 12 months (emergency visits and hospitalizations). The following were associated with drug use for chronic diseases: age ≥ 2 years, Southeast and South regions, and use of health services. For drug use in treating acute conditions, the following associated factors were identified: ≤ 5 years, North, Northeast or Midwest regions, health insurance, and one or more emergency visits. The most commonly used drugs among children under two years of age were paracetamol, ascorbic acid, and dipyrone; for children aged two years or over they were dipyrone, paracetamol, and amoxicillin. The use of medicine by children is considerable, especially in treating acute medical conditions. Children using drugs for chronic diseases have a different demographic profile from those using drugs for acute conditions in relation to gender, age, and geographic region.

O uso de medicamentos para tratar doenças crônicas ou agudas foi referido pelo principal cuidador da criança presente na entrevista domiciliar. Associações entre as variáveis independentes e o uso de medicamentos foram investigadas por meio de regressão de Poisson. A prevalência de uso global de medicamentos foi de 30,7% (IC95% 28,3-33,1). A prevalência de uso de medicamentos para doenças crônicas foi de 5,6% (IC95% 4,7-6,7) e para condições agudas, 27,1% (IC95% 24,8-29,4). Os fatores significativamente associados com o uso global foram ter no máximo cinco anos de idade, residir na região Nordeste, ter plano de saúde e utilizar serviços de saúde nos últimos 12 meses (consultas de emergência e internações). Associaram-se ao uso de medicamentos para doenças crônicas: idade ≥ 2 anos, regiões Sudeste e Sul e utilização de serviços de saúde. Para o uso de medicamentos em condições agudas, foram identificados os seguintes fatores associados: ≤ 5 anos, Norte, Nordeste ou Centro-Oeste, plano de saúde e uma ou mais consultas de emergência. Os medicamentos com maior prevalência de uso pelas crianças menores de dois anos foram paracetamol, ácido ascórbico e dipirona; nas crianças com 2 ou mais anos, foram dipirona, paracetamol e amoxicilina. O uso de medicamentos na população infantil é substancial, principalmente no tratamento de condições médicas agudas. As crianças usuárias de medicamentos para doenças crônicas apresentam perfil demográfico diferente das usuárias de medicamentos para condições agudas, em relação ao sexo, à idade e à região geográfica.

To identify scientific evidence regarding the influence of hormonal contraceptive use and the occurrence of stroke. Integrative review of the literature, through database search using the descriptors "contraceptive agents", "contraceptive devices", "contraceptives, Oral" and "Stroke". Original studies in Portuguese, Spanish and English, published in full and available online were included. Studies that did not answer our guiding questions and duplicated studies were excluded. Women using combined oral contraceptives have higher risk of stroke, even with a lower hormonal dosage and different types of progestogen, regardless of the duration of use. The use of contraceptives associated with smoking, hypertension, migraine, hypercholesterolemia, obesity and sedentary lifestyle increases the chance of stroke. Contraceptive patch and vaginal ring are associated to increased risk. Use of combined hormonal contraceptives, except for the injectable and the transdermal ones, increases the chance of occurrence of the event. Progestogen-only contraceptives were considered safe.

Foram incluídos artigos originais nos idiomas português, espanhol e inglês, publicados na íntegra e disponíveis eletronicamente. Foram excluídos artigos que não respondiam às questões norteadoras e repetidos. Usuárias de anticoncepcional oral combinado apresentam risco maior de AVC, mesmo com dosagem hormonal menor e diferentes tipos de progestágeno, independente do tempo de uso. A presença associada de tabagismo, hipertensão arterial, enxaqueca, hipercolesterolemia, obesidade e sedentarismo aumenta a chance desse desfecho. Adesivo anticoncepcional e anel vaginal são relacionados ao aumento desse risco.

Esta tese apresenta um sistema de localizacao baseado exclusivamente em ultrassons, nao necessitando de recorrer a qualquer outra tecnologia. Este sistema de localizacao foi concebido para poder operar em ambientes onde qualquer outra tecnologia nao pode ser utilizada ou o seu uso esta condicionado, como sao exemplo aplicacoes subaquaticas ou ambientes hospitalares. O sistema de localizacao proposto faz uso de uma rede de farois fixos permitindo que estacoes moveis se localizem. Devido a necessidade de transmissao de dados e medicao de distancias foi desenvolvido um pulso de ultrassons robusto a ecos que permite realizar ambas as tarefas com sucesso. O sistema de localizacao permite que as estacoes moveis se localizem escutando apenas a informacao em pulsos de ultrassons enviados pelos farois usando para tal um algoritmo baseado em diferencas de tempo de chegada. Desta forma a privacidade dos utilizadores e garantida e o sistema torna-se completamente independente do numero de utilizadores. Por forma a facilitar a implementacao da rede de farois apenas sera necessario determinar manualmente a posicao de alguns dos farois, designados por farois ancora. Estes irao permitir que os restantes farois, completamente autonomos, se possam localizar atraves de um algoritmo iterativo de localizacao baseado na minimizacao de uma funcao de custo. Para que este sistema possa funcionar como previsto sera necessario que os farois possam sincronizar os seus relogios e medir a distancia entre eles. Para tal, esta tese propoe um protocolo de sincronizacao de relogio que permite tambem obter as medidas de distancia entre os farois trocando somente tres mensagens de ultrassons. Adicionalmente, o sistema de localizacao permite que farois danificados possam ser substituidos sem comprometer a operabilidade da rede reduzindo a complexidade na manutencao. Para alem do mencionado, foi igualmente implementado um simulador de ultrassons para ambientes fechados, o qual provou ser bastante preciso e uma ferramenta de elevado valor para simular o comportamento do sistema de localizacao sobre condicoes controladas.

Os aglomerados abertos são objetos de grande valor para o estudo da dinâmica da Galáxia devido esses objetos terem uma faixa de idade relativamente ampla. O trabalho visa estudar a dinâmica da estrutura espiral da Galáxia principalmente através do uso desses aglomerados, uma vez que o estudo da cinemática desses objetos é fundamental para esse objetivo. Nosso grupo trabalha no sentido de construir uma base de dados de aglomerados abertos contendo coordenadas, distância, idade, movimentos próprios e velocidades radiais e já disponibiliza uma nova versão do catálogo de aglomerados abertos o qual é uma compilação de edições anteriores, principalmente Lynga (1987), Mermilliod (1995) e ESO-B (Lauberts 1982). Nossa amostra possui cerca de 1630 aglomerados, mas nem todos os parâmetros acima citados foram determinados em sua totalidade. Para determinarmos esses parâmetros, derivamos as cores intrínsecas das estrelas membro de cada aglomerado a partir de seus tipos espectrais (busca feita no SIMBAD) obtendo assim o excesso de cor individual. A distribuição dos excessos de cor foi então utilizada para derivarmos o avermelhamento médio para cada aglomerado. De maneira similar, os tipos espectrais foram usados para estimar as magnitudes absolutas, e com as magnitudes absolutas e aparentes determinamos a respectiva distribuição do módulo de distância e finalmente a distância. Para determinar as idades foram confeccionados os diagramas cor-magnitude das estrelas de cada aglomerado onde foram superpostas a Seqüência Principal de Idade Zero (ZAMS). Superpomos a ZAMS de Schmidt-Kaler e isócronas de composição solar. Essas isócronas foram usadas para determinação das idades dos aglomerados. Uma vez que não temos ainda resultados finais, apresentamos então alguns diagramas cor-magnitude os quais foram usados para determinação, principalmente, da distância e idade dos aglomerados.

INTRODUCTION The scientific production of institutions of higher education, as well as the dissemination and use of this published work by peer institutions, can be assessed by means of quantitative and qualitative measurements. This type of analysis can also serve as the basis of further academic actions. Variables such as the type of evaluation, the number of faculty members and the decision to include or exclude researchers who are not professors are difficult to measure when comparing different schools and institutions. OBJECTIVES The purpose of this study was to assess the scientific production of tenured faculty from the Universidade de São Paulo, Faculdade de Medicina performed from 2001 to 2006. METHODS Medline/PubMed database was considered and the Impact factors (IFs - Journal Citation Report, 2006) and the number of generated citations (Web of Science/ISI Thomson) were also evaluated. RESULTS The analysis of the scientific production of 66 full professors (level MS-6) revealed 1,960 scientific articles published in 630 scientific journals, of which 31.3% were Brazilian and 68.7% were from international sources. Among these, 47% of the articles were published in 62.9% of the journals with IFs above 10, although 16.4% of the journals did not have assigned IF values. We verified that 45% of the published articles received 9,335 citations (average of 11 + 17), with the majority of these (8,968 citations) appearing in international scientific journals. CONCLUSIONS Our results indicate that it is possible to analyze the scientific production of a learning institution by the number of papers published by full professors, taking into account not only their academic position and influence, but also the fact that publication is an opportunity to stimulate joint projects with other members of the same institution.

Fifty nine asthmatic children and adolescents, clinically stable, aged 6 to 15 years, 37 boys and 22 girls, from Instituto da Criança do Hospital das Clínicas da FMUSP, were studied from September to November, 1994. The patients were classified by the clinical score of the International Consensus for Asthma Diagnosis and Management. They performed baseline spirometry and peak expiratory flow rates (PEFR), before and after bronchodilator, and measured PEFR three times a day (6 pm, at bedtime and on waking), for one day, at home. Five PEF measurements were made serially and the best readings were considered. Variability of PFE was calculated for 24 hours, as assessed by maximal amplitude. The results were summited to statistical analysis of the Laboratorio de Informática Médica da Faculdade de Medicina da USP. The results of PEFR and it's variability were compared to spirometry, (functional score, FEV1-forced expiratory volume in the first second) and to the clinical score of the International Consensus for Asthma Diagnosis and Management. In case of disagreement between the clinical parameters, the more severe one was chosen. The clinical score classified 20.3% of our patients as mild obstruction, 49.2% as moderate and 30.5% as severely compromised. According to FEV1, 58% of patients were classified as normal while the PEFR and its variability classified as normal 76% and 71%. The PEFR and it's variability in 24 hours, correlated with the VEF1, as gold standard, showed good specificity, 91% and 76% respectively and low sensibility, 44% and 32%. It was detected a low level of agreement between FEV1, PEFR and it's variability in 24 hours, in the clinical severity classification of asthma. The results of this study showed that FEV1 and PEFR had a low level of agreement in the clinical severity classification of asthma and when they were correlated to the clinical score of the International Consensus, they both presented low sensitivity.

Aspetti deontologici e giuridici della Responsabilità professionale del chirurgo in Italia. Evoluzione storica a partire dal '900.

Picardi, Nicola

2018-01-01

È pleonastico ricordare che ogni individuo raziocinante delle essere responsabile delle sue azioni: deve agire con la coscienza degli scopi che si propone evitando possibili conseguenze negative dei suoi atti. In ambito medico questo tipo di responsabilità è codificata con le norme della "deontologia". Per secoli l'arte terapeutica è stata praticata da individui dotati di una particolare vocazione ed una particolare cultura acquisita da Maestri dell'arte ancor prima che dalla propria esperienza, con nozioni di erboristeria e di elementari conoscenze anatomiche e di fisiologia, circondati da un'aura sacerdotale e da un rispetto derivante dal timore e dall'ammirazione per il coraggio e auspicabilmente dai successi, e facendo riferimento nell'occidente mediterraneo alle regole operative fissate nel Giuramento di Ippocrate, di significato tra il sacro ed il deontologico. Lo sviluppo delle tecniche anestesiologiche a partire dalla seconda metà dell'800 ha determinato l'ampliamento delle iniziative chirurgiche di tipo elettivo, a fianco con gli storici interventi in emergenza per la cura di lesioni traumatiche, ancor prima delle acquisizioni riguardanti le infezioni. Con l'espansione del campo di azione della chirurgia, le possibili complicanze ed i possibili insuccessi hanno fatto da contrappeso ai sentimenti di rispetto e di fiducia nei confronti dei chirurghi, giungendo a far assimilare in tali casi la loro opera quale causa all'origine di danni, provocati rientrando quindi nella categoria dei reati sottoposti alla Legge penale. Così, al termine deontologico di "responsabilità" valido per ogni iniziativa ed ogni professione, per i medici è venuto ad associarsi la qualifica di "professionale", con un significato di presunta colpevolezza. Da una parte le regole deontologiche si sono ampliate, ed hanno coinvolto direttamente il paziente nella fase decisionale delle terapie chirurgiche, formalizzate programmaticamente in moderni codici deontologici ed operativamente nel documento del "consenso informato". Per altro verso le leggi innovative del Codice Civile definito nel 1942, che al posto delle pene del codice penale introduceva il criterio della risarcibilità economica del danno in caso di riconosciuta "responsabilità professionale", ha determinato il coinvolgimento di altre figura professionali, e cioè di avvocati e di medici legali, oltre che delle organizzazioni assicurative, con detrimento alla serenità nell'espletamento delle professioni sanitarie e con l'insorgenza per reazione della cosidetta "medicina difensiva". La concretezza di queste problematiche hanno richiesto l'interessamento attivo della Giurisprudenza con una serie di sentenze, ed una formulazione di decreti e nuove leggi parlamentari, ancora in pieno assestamento nel corso del 2017, lasciano in qualche modo ancora irrisolti alcuni nodi.

To analyze scopes and limits of the use of participatory methodology of evaluation with municipal health managers and administrators. Qualitative research with health policymakers and managers of the Comissão Intergestores Regional (CIR - Regional Interagency Commission) of a health region of the state of Sao Paulo in Brazil. Representatives from seven member cities participated in seven workshops facilitated by the researchers, with the aim of assessing a specific problem of the care line, which would be used as a tracer of the system integrality. The analysis of the collected empirical material was based on the hermeneutic-dialectic methodology and aimed at the evaluation of the applied participatory methodology, according to its capacity of promoting a process of assessment capable to be used as a support for municipal management. With the participatory approach of evaluation, we were able to promote in-depth discussions with the group, especially related to the construction of integral care and to the inclusion of the user's perspective in decision-making, linked to the search for solution to concrete problems of managers. By joint exploration, the possibility of using data from electronic information systems was opened, as well as information coming directly from the users of the services, to enhance discussions and negotiations between partners. The participants were disbelievers of the replication potential of this type of evaluation without the direct monitoring of the academy, given the difficulty of organizing the process in everyday life, already taken by emergency and political issues. Evaluations of programs and services carried out within the Regional Interagency Commission, starting from the local interest and facilitating the involvement of its members by the use of participatory methodologies, can contribute to the construction of integral care. To the extent that the act of evaluating stay invested with greater significance to the local actors, its involvement with the evaluations at the federal level can also be stimulated. Analisar alcances e limites do uso de metodologia participativa de avaliação junto a gestores e gerentes municipais de saúde. Pesquisa qualitativa com gestores e gerentes de saúde da Comissão Intergestores Regional de uma região de saúde do estado de São Paulo. Representantes de sete municípios membros participaram de sete oficinas facilitadas pelos pesquisadores, com o objetivo de avaliar um problema específico da linha de cuidados sob a perspectiva da integralidade. A análise do material empírico coletado baseou-se na metodologia hermenêutica-dialética e visou a avaliação da metodologia participativa aplicada, segundo sua capacidade de promover um processo de avaliação passível de ser utilizado como suporte à gestão municipal. Com a abordagem participativa de avaliação, foi possível promover debates em profundidade com o grupo, principalmente relacionados à construção da integralidade da atenção e à inclusão da perspectiva do usuário na tomada de decisão, de forma vinculada à busca de solução para problemas concretos dos gestores. Mediante a exploração conjunta, foi aberta a possibilidade de utilização de dados advindos dos sistemas eletrônicos de informação, bem como de informações advindas diretamente dos usuários dos serviços, para enriquecer debates e negociações entre parceiros. Os participantes se mostraram descrentes do potencial de replicação deste tipo de avaliação sem o acompanhamento direto da academia, dada a dificuldade de organização do processo no cotidiano, já tomado por questões emergenciais e políticas. Avaliações de programas e serviços realizadas no âmbito da Comissão Intergestores Regional, partindo do interesse local e facilitando o envolvimento de seus membros pelo uso de metodologias participativas, podem contribuir para a construção da integralidade do cuidado. Na medida em que o ato de avaliar fique investido de maior significado para os atores locais, seu envolvimento com as avaliações em nível federal poderá ser também estimulado.

Nesse trabalho procurou-se identificar por meio de um questionário as concepções de Universo, de espaço e tempo que sustentam a visão de mundo de um grupo de 270 estudantes de Ensino Médio, pertencentes a três escolas de São Paulo. As questões relacionadas aos conhecimentos prévios dos estudantes permitiram constatar que há pouco conhecimento acerca dos temas investigados, destacando-se que apenas 20% dos alunos foram capazes de relacionar as semanas com as fases da lua, enquanto 28% associaram as estações do ano à inclinação do eixo de rotação da Terra e 23% tinham noções das distâncias entre objetos celestes próximos da Terra. Enquanto 56% conseguiram relacionar o Big Bang com a origem do Universo, verificou-se que 37% reconheciam ano-luz como unidade de distância e 60% concebiam o Sol como uma estrela. No que se refere às fontes de aquisição que proporcionaram esses conhecimentos, apesar de 60% dos alunos indicarem a escola como principal fonte dos conhecimentos de Ast! ronomia, verificou-se claramente que para a maioria dos alunos seus conceitos ainda são inadequados, havendo necessidade de aprimoramento da abordagem desses conteúdos, pois apesar de popular, a Astronomia ainda é veiculada de maneira pouco esclarecedora e com imprecisões. Nesse contexto, são discutidas algumas possíveis contribuições que podem ser dadas para o ensino de Astronomia pelo uso das ferramentas computacionais nas escolas.

Resumo Contexto A cirurgia bariátrica é considerada a melhor opção para o tratamento da obesidade, cujos pacientes são considerados de alto risco para fenômenos tromboembólicos. Objetivos Comparar o uso de doses diferentes de heparina de baixo peso molecular (HBPM) na profilaxia da trombose venosa profunda (TVP) em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, alteração na dosagem do fator anti-Xa e sangramento pré ou pós-operatório. Métodos Estudo comparativo transversal em pacientes submetidos à cirurgia bariátrica distribuídos em dois grupos, que receberam doses de HBPM de 40 mg (grupo controle, GC) e 80 mg (grupo de estudo, GE). Foram avaliados por ultrassonografia vascular e dosagem de KPTT, TAP, plaquetas e fator anti-Xa. Resultados Foram avaliados 60 pacientes, sendo 34 no GC e 26 no GE. Foi observada diferença significativa somente no peso (p = 0,003) e índice de massa corporal (p = 0,018) no GE em relação ao GC. Não houve diferença na dosagem de KPTT, TAP, plaquetas e fator anti-Xa entre os grupos. Não foram detectados TVP ou sangramentos significativos em ambos os grupos. Conclusões Não houve diferença estatisticamente significativa na utilização de doses maiores de HBPM na profilaxia da TVP em pacientes candidatos à cirurgia bariátrica em relação ao risco de TVP, dosagem do fator anti-Xa e sangramento pré ou pós-operatório.

To analyze variations in the prevalence of chronic use of medicines by older adults in Brazil according to its possible association with the most prevalent chronic diseases and demographic and health factors, and to identify risk factors for polypharmacy. A study based on data from the National Survey on Access, Use and Promotion of Rational Use of Medicines (PNAUM), a cross-sectional, population-based survey with probability sampling in Brazilian urban areas. The independent variable was the number of chronic-use medicines taken by older adults, linked to eight chronic diseases investigated. The intervening variables were gender, age group, marital status, level of education, socioeconomic status, Brazilian region, body mass index, smoking, self-perceived health, hospitalization in the previous year and having health insurance, besides the investigated chronic diseases. A multivariable analysis identified risk factors for polypharmacy. Prevalence of at least one chronic-use medicines among older adults was 93.0%. Of the total number of older adults, 18.0% used at least five medications (polypharmacy). Polypharmacy was higher among the oldest individuals (20.0%), in the South region (25.0%), in those with poor self-perceived health (35.0%), in obese individuals (26.0%), in those with reported health insurance (23.0%) or hospitalization in the previous year (31.0%), and among those who reported any of the investigated diseases, particularly diabetes (36.0%) and heart diseases (43.0%). The variables remaining in the final risk model for polypharmacy were age, region, perceived health, health insurance, hospitalization in the previous year and all investigated diseases except stroke. Older adults with specific diseases have risk factors for polypharmacy modifiable by actions aimed at the rational use of medicines. With the current population aging and successful drug access policy, the trend is an increase in drug use by older adults, which should feature as a priority in the planning agenda of the Brazilian Unified Health System (SUS). Analisar as variações da prevalência do uso crônico de medicamentos por idosos no Brasil segundo sua possível associação com as doenças crônicas mais prevalentes, fatores sociodemográficos e de saúde, e identificar fatores de risco para polifarmácia. Estudo com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos, de caráter transversal e amostra probabilística populacional em municípios brasileiros urbanos. A variável independente foi o número de medicamentos de uso crônico por idosos, vinculados às oito doenças crônicas investigadas. As variáveis intervenientes foram sexo, faixa etária, situação conjugal, escolaridade, nível socioeconômico, região do País, índice de massa corporal, hábito de fumar, percepção da própria saúde, internação no último ano e posse de plano de saúde privado, além das doenças crônicas referidas. Uma análise multivariável identificou os fatores de risco para polifarmácia. A prevalência de pelo menos um medicamento de uso crônico entre idosos foi de 93,0%. Do total de idosos, 18,0% utilizavam pelo menos cinco medicamentos (polifarmácia). A polifarmácia foi maior entre os mais idosos (20,0%), na região Sul (25,0%), nos que avaliaram a própria saúde como ruim (35,0%), nos obesos (26,0%), nos que referiram ter plano de saúde (23,0%) ou internação no último ano (31,0%) e entre os que referiram qualquer uma das doenças investigadas, particularmente diabetes (36,0%) e doenças cardíacas (43,0%). No modelo final de risco para polifarmácia permaneceram idade, região, percepção de saúde, posse de plano de saúde, internação no último ano e todas as doenças investigadas exceto acidente vascular cerebral. Idosos com doenças específicas têm fatores de risco para polifarmácia modificáveis por ações que visem o uso racional de medicamentos. Com o envelhecimento populacional em curso e a política exitosa de acesso a medicamentos, a tendência é aumentar a utilização de medicamentos por idosos, que deve ser prioridade na agenda de planejamento do Sistema Único de Saúde.

OBJECTIVE: Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma, accounting for nearly 50% of the cases in the Hematology Department of the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo and Instituto do Câncer do Estado de São Paulo. The treatment outcome is influenced by age, abnormal lactate dehydrogenase levels, extranodal infiltration, the disease stage and the patient's performance status. In this study, we sought to report the time-to-treatment of diffuse large B-cell lymphoma in São Paulo's public health system network and its impact on patient outcomes. METHODS: We prospectively followed a cohort of 42 consecutive patients with de novo diffuse large B-cell lymphoma between 2008 and 2012. RESULTS: Our patients had more advanced disease than that reported in the literature (61.9% vs. 46%). In São Paulo's public health system network, it took an average of 7.4 months for a diagnosis to be made and an additional 1.4 months to obtain an appointment with a specialist. Once at our Hematology Department, it took less than 20 days for staging, confirmation of the diagnosis and treatment initiation. An interval from signs or symptoms to treatment of more than 6 months was associated with inferior progression-free survival in 3 years (p = 0.049). CONCLUSION: A delay in the diagnosis of diffuse large B-cell lymphoma is a public health problem and may be associated with worse progression-free survival. PMID:24838904

O radiotelescópio do Itapetinga tem sido utilizado em campanhas de observações de explosões solares gerando um grande número de mapas diários em 48 GHz como sub-produto destas observações. A resolução espacial do telescópio de 14m do Itapetinga nesta freqüência é de aproximadamente dois minutos de arco. Estruturas de interesse para análise da atmosfera solar quiescente tais como os filamentos e o anel de abrilhantamento do limbo são de dimensão angular moderada da ordem ou ligeiramente menores que a resolução do telescópio. É conhecido que a convolução da função de espalhamento do telescópio, PSF (padrão de ganho do feixe) borra as estruturas de dimensão angular abaixo do HPBW (largura a meia potência do feixe) e portanto é comum a busca por técnicas de restauração que eliminem pelo menos em parte este borramento. Estudamos a restauração destas radioimagens usando a técnica de regularização adaptativa e os resultados ressaltam estas estruturas espaciais de pequeno contraste. O algoritmo da regularização adaptativa faz uso de k imagens, chamadas protótipos, obtidas através da variação de parâmetros de um filtro de regularização. Para controle da qualidade da restauração utilizamos uma imagem de alta resolução espacial obtida na linha H-a e a PSF do Itapetinga para borrá-la. Pequenos desvios, entre a PSF utilizada para o borramento e a PSF utilizada na restauração, produziram alguns desvios notáveis na imagem restaurada porém a adição de ruído nas simulações de restauração foram mais influentes no cálculo da rugosidade da imagem e portanto mais limitante para a restauração. Apresentamos como nosso primeiro resultado uma imagem em 48 GHz com a presença clara do abrilhantamento de limbo que não estava evidente na imagem original e traços de estruturas filamentares, porém ainda sem grande evidência.

A Rede Neural Artificial (RNA), no âmbito da teoria computacional, constitui uma teoria emergente que, por possuir habilidade em aprender a partir de dados de entrada, encontra diferentes aplicações em diferentes áreas. Um exemplo é a utilização de RNA na caracterização de padrões associados à dinâmica de processos espaço-temporais relacionados a fenômenos físicos não-lineares. Para obter informações sobre o comportamento destes fenômenos físicos utiliza-se, em diversos casos, seqüências de imagens digitalizadas, onde a caracterização de alguns fenômenos espaço-temporais é o procedimento mais viável para descrever a dinâmica das regiões ativas do Sol. Com base em imagens observadas por telescópios a bordo de satélites, estudos de previsão de eventos solares podem ser programados, permitindo prever possíveis efeitos posteriores nas regiões mais próximas da Terra (tempestades geomagnéticas e irregularidades ionosféricas). Neste trabalho avaliamos o desempenho da RNA para estimar padrões espaço-temporais, ou seja, imagens solares em ultravioleta, obtidas através do telescópio a bordo do satélite SOHO. Os resultados mostraram que as RNA conseguem generalizar os padrões de maneira satisfatória sem perder de forma significativa os principais aspectos da configuração global da atmosfera solar, comprovando a eficácia da RNA como ferramenta para esse tipo de aplicação. Portanto, este trabalho comprova a viabilidade de uso desta ferramenta em projetos voltados ao estudo do comportamento solar, em trabalhos do grupo de Física do Meio Interplanetário (FMI) na DAS e em programas desenvolvidos pelo Núcleo de Simulação e Análise de Sistemas Complexos (NUSASC) do Laboratório Associado de Computação e Matemática Aplicada (LAC) do INPE.

To analyze factors associated with low adherence to drug treatment for chronic diseases in Brazil. Analysis of data from Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - Brazilian Survey on Access, Use and Promotion of Rational Use of Medicines), a population-based cross-sectional household survey, based on a probabilistic sample of the Brazilian population. We analyzed the association between low adherence to drug treatment measured by the Brief Medication Questionnaire and demographic, socioeconomic, health, care and prescription factors. We used Poisson regression model to estimate crude and adjusted prevalence ratios, their respective 95% confidence interval (95%CI) and p-value (Wald test). The prevalence of low adherence to drug treatment for chronic diseases was 30.8% (95%CI 28.8-33.0). The highest prevalence of low adherence was associated with individuals: young adults; no education; resident in the Northeast and Midwest Regions of Brazil; paying part of the treatment; poor self-perceived health; three or more diseases; reported limitations caused by a chronic disease; using five drugs or more. Low adherence to drug treatment for chronic diseases in Brazil is relevant, and regional and demographic differences and those related to patients' health care and therapy regime require coordinated action between health professionals, researchers, managers and policy makers.

Análise de dados oriundos da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), inquérito domiciliar de base populacional, de delineamento transversal, baseado em amostra probabilística da população brasileira. Analisou-se a associação entre baixa adesão ao tratamento medicamentoso mensurado pelo Brief Medication Questionnaire e fatores demográficos, socioeconômicos, de saúde, assistência e prescrição. Foi utilizado modelo de regressão de Poisson para estimar as razões de prevalência brutas e ajustadas, os respectivos intervalos de 95% de confiança (IC95%) e p-valor (teste de Wald). A prevalência de baixa adesão ao tratamento farmacológico de doenças crônicas foi de 30,8% (IC95% 28,8-33,0). As maiores prevalências de baixa adesão estiveram associadas a indivíduos: adultos jovens; que nunca estudaram; residentes na região Nordeste e Centro-Oeste do País; que tiveram que pagar parte do tratamento; com pior autopercepção da saúde; com três ou mais doenças; que referiam limitação causada por uma das doenças crônicas; e que faziam uso de cinco medicamentos ou mais. A baixa adesão ao tratamento medicamentoso para doenças crônicas no Brasil é relevante e as diferenças regionais, demográficas e aquelas relacionadas à atenção à saúde do paciente e ao regime terapêutico requerem ações coordenadas entre profissionais de saúde, pesquisadores, gestores e formuladores de políticas para o seu enfrentamento.

To evaluate the relation between diabetes-related distress and the clinical and sociodemographic characteristics of type 2 diabetes mellitus patients. A cross-sectional study based on a secondary analysis of data collected at a specialized care outpatient center in Brazil. Participants completed a questionnaire on sociodemographic and clinical characteristics and the Brazilian version of the Diabetes Distress Scale (B-DDS). About 31% of the 130 eligible patients reported diabetes distress, and the mean B-DDS score was 2.6. Multiple regression analysis showed the B-DDS score was positively correlated with marital status (p=0.0230), use of diet and physical activities for diabetes management (p=0.0180), and use of insulin therapy (p=0.0030). The "emotional burden", "regimen-related distress", and "interpersonal distress" domains from B-DDS were associated with the use of insulin therapy (p=0.0010), marital status (p=0.0110), and the presence of three or more comorbidities (p=0.0175). These findings suggest the clinical and sociodemographic variables are relatively weak predictors of diabetes-related distress. The highest scores in the B-DDS were observed in the emotional burden domain, indicating the presence of diabetes distress among the participants of the study. Avaliar a relação entre o estresse relacionado ao diabetes e as características clínicas e sociodemográficas de pacientes com diabetes mellitus do tipo 2. Estudo transversal com base na análise secundária de dados coletados em um ambulatório de atendimento terciário no Brasil. Os participantes preencheram um questionário sobre as características sociodemográficas e clínicas, e a versão brasileira da Diabetes Distress Scale (B-DDS). Aproximadamente 31% dos 130 pacientes elegíveis relataram estresse relacionado ao diabetes, e a média do escore da B-DDS foi de 2,6. O modelo de regressão múltipla mostrou que a pontuação B-DDS foi positivamente correlacionada com o estado civil (p=0,0230), realização de dieta e atividades físicas (p=0,0180), e uso de insulina (p=0,0030). Os domínios da B-DDS "carga emocional", "estresse relacionado ao regime terapêutico" e "estresse nas relações interpessoais" foram associados a uso de insulina (p=0,0010), estado civil (p=0,0110) e presença de três ou mais comorbidades (p=0,0175). Estes resultados sugerem que as variáveis clínicas e sociodemográficas são preditores relativamente fracos para o estresse relacionado ao diabetes. No domínio "carga emocional", foi observada a maior pontuação da B-DDS, indicando a presença do estresse relacionado ao diabetes entre os pacientes deste estudo.

Effects of illumination functions on the computation of gravity-dependent signal path variation models in primary focus and Cassegrainian VLBI telescopes

Abbondanza, Claudio; Sarti, Pierguido

2010-08-01

This paper sets the rules for an optimal definition of precise signal path variation (SPV) models, revising and highlighting the deficiencies in the calculations adopted in previous studies and improving the computational approach. Hence, the linear coefficients that define the SPV model are rigorously determined. The equations that are presented depend on the dimensions and the focal lengths of the telescopes as well as on the feed illumination taper. They hold for any primary focus or Cassegrainian very long baseline interferometry (VLBI) telescope. Earlier investigations usually determined the SPV models assuming a uniform illumination of the telescope mirrors. We prove this hypothesis to be over-simplistic by comparing results derived adopting (a) uniform, (b) Gaussian and (c) binomial illumination functions. Numerical computations are developed for AZ-EL mount, 32 m Medicina and Noto (Italy) VLBI telescopes, these latter being the only telescopes which possess thorough information on gravity-dependent deformation patterns. Particularly, assuming a Gaussian illumination function, the SPV in primary focus over the elevation range [0°, 90°] is 10.1 and 7.2 mm, for Medicina and Noto, respectively. With uniform illumination function the maximal path variation for Medicina is 17.6 and 12.7 mm for Noto, thus highlighting the strong dependency on the choice of the illumination function. According to our findings, a revised SPV model is released for Medicina and a model for Noto is presented here for the first time. Currently, no other VLBI telescope possesses SPV models capable of correcting gravity-dependent observation biases.

To present a high school insertion pilot project in post graduate programs (PPG) and discuss the mechanisms for the formation of leaders in science. This study presents a review and pilot project. Bibliographic search occurred in sites of CAPES, MEC, SciELO and library of virtual books from January/ 2014 to February/2015. The pilot is in PPG-Medicine III Translational Surgery/UNIFESP and Pathophysiology and Surgical Sciences / UERJ. The junior undergraduate students (ICj) came from public school and develop scientific activities: scientific meetings, graduation and inclusion in research projects. The evaluation will occur at the end of one year, with the results essays, reports and participation in scientific events. In Brazil, one of the main challenges of education is the high average years of study. The PNPG (2011-2020) shows the insertion of basic education in all PPG. In the Pathophysiology and Surgical Sciences/UERJ there are currently 11 high school students who have followed the scientific meetings and are being prepared for the inclusion in research projects. There was 30% of absence, owing to the high school hours. This result and the experience allow creating future alternatives to enhance the integration project. The leadership in science is formed from a complex relationship between basic education and investment in research. PPG-Medicine III courses follow the vanguard with initiatives focused on scientific and technological development. Thus, projects involving basic education students represent promoter model and environment leaders.

Realizou-se um estudo de revisão e apresentação de piloto. A busca bibliográfica ocorreu nos sites da CAPES, MEC, Scielo e biblioteca de livros virtuais, de janeiro/2014 a fevereiro/2015. O piloto ocorre nos PPG-Medicina III em Cirurgia Translacional/UNIFESP e Fisiopatologia e Ciências Cirúrgicas/UERJ. Os alunos de iniciação científica júnior (ICj) são oriundos de escola pública e desenvolvem atividades científicas: participação em reuniões científicas, graduação e inserção nos projetos de pesquisa. A avaliação ocorrerá ao final de um ano, com redações dos resultados, relatórios e participações em eventos científicos. No Brasil, um dos principais desafios da educação é a alta média de anos de estudo. O PNPG (2011-2020) apresenta a inserção da educação básica em todos os PPG. Na Fisiopatologia e Ciências Cirúrgicas/UERJ há atualmente 11 alunos do ensino médio, que já acompanharam as reuniões científicas e preparam-se para a inserção em projetos de pesquisa. Houve 30% de desistência, devido à alta carga horária escolar. Esse resultado e a experiência vivenciada permite criar alternativas futuras para aprimorar o projeto de inserção. A liderança em ciências é formada a partir de uma complexa relação entre educação básica e investimentos na pesquisa. Cursos de PPG-Medicina III seguem na vanguarda com iniciativas focadas no desenvolvimento científico e tecnológico. Assim, projetos envolvendo alunos da educação básica representam modelo e ambiente promotor de líderes.

To identifyevidences of the influence of nursing workload on the occurrence of adverse events (AE) in adult patients admitted to the intensive care unit (ICU). A systematic literature review was conducted in the databases MEDLINE, CINAHL, LILACS, SciELO, BDENF, and Cochrane from studies in English, Portuguese, or Spanish, published by 2015. The analyzed AE were infection, pressure ulcer (PU), patient falls, and medication errors. Of 594 potential studies, eight comprised the final sample of the review. TheNursing Activities Score (NAS; 37.5%) and the Therapeutic Intervention Scoring System(TISS; 37.5%) were the instruments most frequently used for assessing nursing workload. Six studies (75.0%) identified the influence of work overload in events of infection, PU, and medicationerrors. An investigation found that the NAS was a protective factor for PU. The nursing workload required by patients in the ICU influenced the occurrence of AE, and nurses must monitor this variable daily to ensure proper sizing of staff and safety of care.

Os EA analisados foram infecção, úlcera por pressão (UPP), quedas e erros associados a medicamentos. Das 594 pesquisas potenciais identificadas, oito compuseram a amostra final da revisão. O NursingActivities Score -NAS (37,5%) e o TherapeuticInterventionScoring System -TISS (37,5%) foram os instrumentos mais utilizados para avaliação da carga de trabalho de enfermagem. Seis pesquisas (75,0%) identificaram influência da sobrecarga de trabalho na ocorrência de infecção, UPP e uso de medicamentos. Uma investigação identificou que o NAS foi fator de proteção para UPP. A carga de trabalho de enfermagem requerida por pacientes na UTI influenciou a ocorrência de EA, e os enfermeiros devem monitorar diariamente esta variável para garantir o correto dimensionamento da equipe e a segurança da assistência prestada.

Multi-technique approach for deriving a VLBI signal extra-path variation model induced by gravity: the example of Medicina

NASA Astrophysics Data System (ADS)

Sarti, P.; Abbondanza, C.; Negusini, M.; Vittuari, L.

2009-09-01

During the measurement sessions gravity might induce significant deformations in large VLBI telescopes. If neglected or mismodelled, these deformations might bias the phase of the incoming signal thus corrupting the estimate of some crucial geodetic parameters (e.g. the height component of VLBI Reference Point). This paper describes a multi-technique approach implemented for measuring and quantifying the gravity-dependent deformations experienced by the 32-m diameter VLBI antenna of Medicina (Northern Italy). Such an approach integrates three different methods: Terrestrial Triangulations and Trilaterations (TTT), Laser Scanning (LS) and a Finite Element Model (FEM) of the antenna. The combination of the observations performed with these methods allows to accurately define an elevation-dependent model of the signal path variation which appears to be, for the Medicina telescope, non negligible. In the range [0,90] deg the signal path increases monotonically by almost 2 cm. The effect of such a variation has not been introduced in actual VLBI analysis yet; nevertheless this is the task we are going to pursue in the very next future.

The Simultaneous Medicina-Planck Experiment (SiMPlE) is aimed at observing a selected sample of 263 extragalactic and Galactic sources with the Medicina 32-m single-dish radio telescope in the same epoch as the Planck satellite observations. The data, acquired with a frequency coverage down to 5 GHz and combined with Planck at frequencies above 30 GHz, will constitute a useful reference catalogue of bright sources over the whole Northern hemisphere. Furthermore, source observations performed in different epochs and comparisons with other catalogues will allow the investigation of source variabilities on different time-scales. In this work, we describe the sample selection, the ongoing data acquisition campaign, the data reduction procedures, the developed tools and the comparison with other data sets. We present 5 and 8.3 GHz data for the SiMPlE Northern sample, consisting of 79 sources with δ≥ 45° selected from our catalogue and observed during the first 6 months of the project. A first analysis of their spectral behaviour and long-term variability is also presented.

The flight performance of the Galileo orbiter USO

1993-01-01

Results are presented from an analysis of radio metric data received by the DSN stations from the Galileo spacecraft using an Ultrastable Oscillator (USO) as a signal source. These results allow the health and performance of the Galileo USO to be evaluated, and are used to calibrate this Radio Science instrument and the data acquired for Radio Science experiments such as the Red-shift Observation, Solar Conjunction, and Jovian occultations. Estimates for the USO-referenced spacecraft-transmitted frequency and frequency stability were made for 82 data acquisition passes conducted between launch (October 1989) and November 1991. Analyses of the spacecraft-transmitted frequencies show that the USO is behaving as expected. The USO was powered off and then back on in August 1991 with no adverse effect on its performance. The frequency stabilities measured by Allan deviation are consistent with expected values due to thermal wideband noise and the USO itself at the appropriate time intervals. The Galileo USO appears to be healthy and functioning normally in a reasonable manner.

To develop a proposal for metrics for patents to be applied in assessing the postgraduate programs of Medicine III - Capes. From the reading and analysis of the 2013 area documents of all the 48 areas of Capes, a proposal for metrics for patents was developed to be applied in Medicine III programs. Except for the areas Biotechnology, Food Science, Biological Sciences III, Physical Education, Engineering I, III and IV and Interdisciplinary, most areas do not adopt a scoring system for patents. The proposal developed was based on the criteria of Biotechnology, with adaptations. In general, it will be valued, in ascending order, the deposit, the granting and licensing/production. It will also be assigned higher scores to patents registered abroad and whenever there is a participation of students. This proposal can be applied to the item Intellectual Production of the evaluation form, in subsection Technical Production/Patents. The percentage of 10% for academic programs and 40% for Masters Professionals should be maintained. The program will be scored as Very Good when it reaches 400 points or over; Good, between 200 and 399 points; Regular, between 71 and 199 points; Weak up to 70 points; Insufficient, no punctuation.

Resumo Contexto Embora preconizada, a profilaxia de tromboembolismo venoso (TEV) deixa de ser realizada sistematicamente em pacientes internados. Objetivo Verificar se os pacientes hospitalizados recebem a prescrição correta da profilaxia de TEV do médico responsável por sua internação, conforme sua categoria de risco. Métodos Estudo transversal com análise de prontuários de pacientes internados no Hospital Santa Casa de Misericórdia de Curitiba, PR, entre 20 de março e 25 de maio de 2015. Excluíram-se os pacientes em uso de anticoagulantes ou com sangramento ativo. Analisou-se gênero, idade, tipo de cobertura de saúde, especialidade responsável pelo paciente e fatores de risco dos pacientes para classificá-los em alto, moderado ou baixo risco para TEV. Comparou-se o uso ou não da profilaxia entre as prescrições das especialidades clínicas e cirúrgicas, pacientes internados pelo Sistema Único de Saúde (SUS) e por convênios e de acordo com seu risco para TEV. Resultados Dos 78 pacientes avaliados, oito preencheram os critérios de exclusão. Dos 70 pacientes elegíveis (média etária 56,9 anos; 41 homens; 62 cobertos pelo SUS), 31 eram tratados por clínicos e 39 por cirurgiões. Apenas 46 (65,71%) pacientes receberam profilaxia para TEV. Dentre os pacientes clínicos, 29 (93,5%) receberam profilaxia, contra 17 (43,6%) do grupo cirúrgico (p < 0,001). Pacientes clínicos de moderado e alto risco receberam mais profilaxia que os cirúrgicos (p < 0,001 e p = 0,002). Não houve diferenças quanto à cobertura de saúde (SUS versus convênios médicos). Conclusões No Hospital Santa Casa de Misericórdia de Curitiba, pacientes cirúrgicos estão menos protegidos de eventos tromboembólicos em relação aos clínicos. PMID:29930647

Pharmacological literature in the Late Antique period followed the Roman tradition and widely used Scribonius Largus and excerpts from the writings of Pliny the Elder. Literature was created both in the western part of the Roman Empire and in North Africa in Carthage. Manuals have been written about medicinal plants (Herbarius of Pseudo-Apuleius, De herba vettonica of Pseudo-Musa), for drugs obtained from the animal kingdom (Liber medicinae of Sextus Placitus) or documents containing both (De medicina of Cassius Felix, De medicamentis of Marcellus Empiricus). The contribution of this literature is the mediation of ancient knowledge into the Middle Ages.

to analyze the social representations of health care of the Mbyá-Guarani ethnic group by multidisciplinary teams from the Special Indigenous Health District in the south coast of Rio Grande do Sul state (Distrito Sanitário Especial Indígena Litoral Sul do Rio Grande do Sul), Brazil. a qualitative method based on the theory of social representations was used. Data were collected via semi-structured interviews with 20 health workers and by participant observation. The interviews were analyzed with ALCESTE software, which conducts a lexical content analysis using quantitative techniques for the treatment of textual data. there were disagreements in the health care concepts and practices between traditional medicine and biomedicine; however, some progress has been achieved in the area of intermedicality. The ethnic boundaries established between health workers and indigenous peoples based on their representations of culture and family, together with the lack of infrastructure and organization of health actions, are perceived as factors that hinder health care in an intercultural context. a new basis for the process of indigenous health care needs to be established by understanding the needs identified and by agreement among individuals, groups, and health professionals via intercultural exchange. analisar as representações sociais do cuidado em saúde entre trabalhadores que atuam em equipes multidisciplinares no Distrito Sanitário Especial Indígena Litoral Sul do Rio Grande do Sul, junto à etnia Mbyá-Guarani. utilizou-se método qualitativo, fundamentado na teoria das Representações Sociais. Os dados foram coletados por meio de entrevistas semiestruturadas com 20 trabalhadores e da observação participante.

[Translation of titles into English in Medicina Clínica: quality and influence of the Spanish language].

Navarro, F A; Barnes, J

Journals that are not published solely in English have the titles of papers translated into English, the international language of medicine. The aim of this paper is to analyse the accuracy and quality of such translations in Medicina Clínica and to assess the influence of the morphology and syntax of Spanish on the English versions of the titles. Two professional medical translators, one Spanish and the other English, each with a knowledge of both languages, compared the original Spanish and the English translations of the titles of the 292 papers and communications published in the 20 issues of volume 100 of Medicina Clínica. The discrepancies or "errors" were classified in five groups of increasing seriousness. Of the titles studied, 77% contained some sort of error (458 errors were detected). In 100 titles (34%) there were differences in meaning between the original Spanish and the English translations. Another 72 titles contained serious orthographical, lexical or grammatical mistakes, though the basic meaning was not distorted. Approximately a third of the lexical and grammatical errors were attributable to the direct influence of Spanish. The English translations of titles in Medicina Clínica contain numerous orthographical, lexical and gammatical mistakes. Serious errors of meaning in a number of translated titles could result in misinterpretation by readers who do not know Spanish. We recommend that the authors should play a part in the translation of the titles, as this should provide a simple and effective mean of improving the accuracy of the translations. Our comparison yielded much worse results than had been expected, which suggests that similar studies with other medical journals in Spanish and other languages would be justified.

ESO-LV 5100550 é o membro mais fraco do par de galáxias austral SBG 357 (Soares et al. 1995). É classificada no catálogo RC3 como uma espiral ordinária de tipo inicial (early-type); porém, uma análise morfológica sugere que ela tenha uma grande barra. O objetivo do estudo é determinar sua cinemática de tal modo que possamos inferir mais a respeito de sua dinâmica, provavelmente perturbada, já que se espera que esteja sob forte influência da companheira ESO-LV 5100560. Apresentarei resultados parciais determinados a partir de espectros obtidos com o instrumento Double Spectrograph montado no telescópio Hale do Monte Palomar, EUA. As observações foram realizadas por D.S.L. Soares, P.M.V. Veiga e T.E. Nordgren, em 1998. Foram tomados espectros de fenda longa posicionada sobre a linha dos nodos do disco e ao longo da suposta barra. Os dados foram reduzidos com uso do pacote IRAF. Obtivemos o perfil de velocidades radiais na linha de visada ao longo das fendas e calculamos o desvio para o vermelho cosmológico do sistema, com base no espectro central. Determinamos as curvas de rotação deprojetadas, com base em cálculos para os valores teóricos esperados das componentes de velocidades puramente circulares em um disco inclinado. A inclinação do disco, dado fundamental nesta deprojeção, foi estimada através da média das elipticidades das isofotas mais externas.

A serological inquiry was performed in the municipality of Sena Madureira, Acre State, Brazil, to evaluate the individual contact with Echinococcus sp. The participants were recruited from two distinct populations: residents in the urban and rural areas, the latter distributed among riverside communities of the region. A total of 1,064 individuals were evaluated: 851 from the urban zone and 213 from the rural area. The study was divided into two phases: a serological screening, in which the blood samples were collected and then sent to the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo (Serology Laboratory), Ribeirão Preto, SP, Brazil, for the serological test by counterimmunoelectrophoresis technique; and secondly an epidemiological inquiry for evaluating the individuals and their dwelling conditions and customs. Comparing the results of serological tests, the prevalence in the rural area was 6% against 3.5% in the urban area. The overall prevalence was 4%. The possibility of the existence of another intermediate host in the life cycle of Echinococcus vogeli was analyzed and the findings indicated the domestic pig as being the most probable.

To assess the ownership and use of mosquito nets in 2014, in Mozambique. This observational and cross-sectional study assessed, in February and March 2015, 69 districts (nine of 11 provinces of Mozambique) that have benefited from the mass distribution of mosquito nets. The Lot Quality Assurance Sampling methodology was used. Each locality was denominated supervision area. The Lot Quality Assurance Sampling opts for a minimum of 19 households (in this case, we decided for a minimum of 100 households per district) from each supervision area to assess an indicator (in this case, two indicators were assessed: ownership and use of mosquito nets). Two questions guided the research: a) received a mosquito net; b) used a mosquito net the night before. A total of 6,725 households were assessed. Eighty three percent of them had received mosquito nets in the campaign. Of the 6,232 respondents, 82.0% said they used mosquito nets the night before. The districts of the provinces with low coverage of ownership and use were Tete (69.5% and 60.0%, respectively), Zambezia (79.0% and 60.0%, respectively), and Gaza (81.6% and 70.7%, respectively). The largest coverage of ownership and use were observed in the districts of Nampula (96.7% and 93.8%, respectively) and Niassa (86.0% and 85.4% respectively). In the districts assessed, the progression of ownership and use of mosquito nets is satisfactory. Nampula and Niassa are the only provinces where ownership and use are at desired levels.

Usou-se a metodologia Lot Quality Assurance Sampling. Cada localidade foi designada de área de supervisão. O Lot Quality Assurance Sampling opta por um mínimo de 19 agregados familiares (neste caso decidiu-se um mínimo de 100 agregados familiares por distrito) de cada área de supervisão, a fim de avaliar um indicador (neste caso dois indicadores foram avaliados: posse e uso de redes mosquiteiras). Duas perguntas nortearam a pesquisa: a) recebeu rede; b) usou rede na noite anterior. Foram avaliados 6.725 agregados familiares . Desses, 83,0% tinham recebido redes na campanha. Dos 6.232 inqueridos, 82,0% disseram que usaram na noite anterior. As províncias com distritos com menores coberturas de posse e uso foram Tete (69,5% e 60,0%, respectivamente), Zambézia (79,0% e 60,0%, respectivamente) e Gaza (81,6% e 70,7%, respectivamente). As maiores coberturas de posse e uso foram observadas nos distritos de Nampula (96,7% e 93,8%, respectivamente) e Niassa (86,0% e 85,4%, respectivamente). Nos distritos avaliados, a progressão para a posse e uso de redes mosquiteiras é satisfatória. Nampula e Niassa são as únicas províncias onde a posse e o uso estão em níveis desejados.

Bullous systemic lupus erythematosus has rarely been described in pediatric lupus population and the real prevalence of childhood-onset bullous systemic lupus erythematosus has not been reported. From January 1983 to November 2013, 303 childhood-onset SLE (c-SLE) patients were followed at the Pediatric Rheumatology Unit of the Childreńs Institute of Hospital das Clínicas da Faculdade de Medicina Universidade da Universidade de São Paulo, three of them (1%) diagnosed as childhood-onset bullous systemic lupus erythematosus. All three cases presented tense vesiculobullous lesions unassociated with lupus erythematosus lesions, with the median duration of 60 days (30-60). All patients fulfilled bullous systemic lupus erythematosus criteria. Two had nephritis and serositis and presented specific autoantibodies. The histological pattern demonstrated subepidermal blisters with neutrophils-predominant infiltrates within the upper dermis. Direct immunofluorescence (DIF) showed deposits of IgG and complement along the epidermal basement membrane, in the presence or absence of IgA and/or IgM. A positive indirect immunofluorescence on salt-split skin demonstrating dermal binding was observed in two cases. All of them had moderate/severe disease activity at diagnosis with median Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) of 18 (14-24). Two patients received dapsone and one with severe nephritis received immunosuppressive drugs. In conclusion, in the last 30 years the prevalence of bullous lupus in childhood-onset lupus population was low (1%) in our tertiary University Hospital. A diagnosis of SLE should always be considered in children with recurrent tense vesiculobullous lesions with or without systemic manifestations. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

In this manuscript, we present the repair of a large IH following liver transplantation through the technique of posterior components separation combined with the anterior, together with the intraoperative use of botulinum toxin A and the placement of mesh. As a secondary objective, we analyze the incidence of IH following liver transplantation in our service. Between the years 2013 and 2016, 247 patients underwent liver transplantation in the Liver Transplantation Service at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, Brazil. We analyzed the incidence of IH in these patients. One of these cases operated in March 2017 presented a defect in the abdominal wall of 22×16.6×6.4cm in the median and paramedian regions. We present the details of this innovative surgical technique. The total operating time was 470min. During the postoperative phase the patient presented ileus paralysis, without systemic repercussions. Resumption of an oral diet on the fifth postoperative day, without incident. Hospital discharge occurred on the 12th postoperative day, with outpatient follow up. In our service, the incidence of incisional hernias following liver transplantation is 14.5%. We described a successful approach for selected patient group for whom there is no established standard treatment. Given the complexity of such cases, however, more studies are necessary.

"Medicina Paliativa" is the official journal of the Spanish Society of Palliative Care ("Sociedad Española de Cuidados Paliativos"; SECPAL) and it reflects the interests, also on bioethics, of the professionals caring terminal people. We want to know what the bioethical questions they discuss and their approaches are. From all the published articles in "Medicina Paliativa" from 1994 to 2013 we selected those referred to bioethics topics. We analysed: number of publications, author, subtype of article, year of publication, topic, philosophic approach, and the presence of answers and discussion. Qualitative topics were reviewed and agreed by at least two authors. There were 60 (9%) publications with bioethics profile from a total of 672 analyzed articles. A majority were signed by only one author. 31 (51%) were published as letter. The most relevant topics were: euthanasia, dignity, proportionality of treatment and care, sedation, principles of bioethics, and information. The orientation of these papers was, in a majority, according to principles of palliative care. Most bioethics topics have been answered and even answered back. Bioethics is an interesting topic in palliative care. The arguments usually fit the principles of palliative care.

Researchers have used data from the GRAIL mission to the Moon to make the first in-flight verification of ultra-stable oscillators (USOs) with Allan deviation below 10 13 for 1-to-100-second averaging times. USOs are flown in space to provide stable timing and/or navigation signals for a variety of different science and programmatic missions. The Gravity Recovery and Interior Laboratory (GRAIL) mission is flying twin spacecraft, each with its own USO and with a Ka-band crosslink used to measure range fluctuations. Data from this crosslink can be combined in such a way as to give the relative time offsets of the two spacecrafts USOs and to calculate the Allan deviation to describe the USOs combined performance while orbiting the Moon. Researchers find the first direct in-space Allan deviations below 10(exp -13) for 1-to-100-second averaging times comparable to pre-launch data, and better than measurements from ground tracking of an X-band carrier coherent with the USO. Fluctuations in Earth s atmosphere limit measurement performance in direct-to-Earth links. Inflight USO performance verification was also performed for GRAIL s parent mission, the Gravity Recovery and Climate Experiment (GRACE), using both Kband and Ka-band crosslinks.

Resumo Contexto Faz-se importante o conhecimento técnico dos ajustes de potência e de densidade de energia linear endovenosa (linear endovenous energy density, LEED) adequados para atingir o objetivo final da termoablação endovenosa (endovenous laser ablation, EVLA). Objetivos Avaliar a influência de diferentes LEEDs em termos de patência e presença de refluxo, bem como determinar a evolução clínica. Métodos Foram incluídas 60 veias safenas magnas (VSM). Os pacientes foram randomizados em dois grupos: EVLA com baixa potência (7 W e LEED de 20-40 J/cm) e com alta potência (15 W e LEED de 80-100 J/cm). O acompanhamento com eco-Doppler e escore de severidade clínica venoso (VCSS) foi realizado nos intervalos de 3-5 dias, 30 dias, 180 dias e 1 ano após o procedimento. Resultados Dezoito pacientes (29 membros) tratados com 7W de potência e 13 pacientes (23 membros) com 15 W completaram o estudo. Não houve diferença significativa considerando idade, tempo de cirurgia e o uso de analgésicos, lateralidade, gênero e presença de comorbidades. O LEED médio foi de 33,54 J/cm no grupo de 7 W e de 88,66 J/cm no de 15 W. Ambos apresentaram melhora no VCSS, redução significativa dos diâmetros da JSF e ausência de diferença significativa quanto ao aumento do comprimento do coto da VSM e de refluxo após o tratamento. Conclusões A utilização de maior densidade de energia mostrou-se mais efetiva em relação à estabilização do comprimento do coto da VSM e do refluxo em 6 meses. Fazem-se necessários estudos com um período de acompanhamento maior para fundamentar essa hipótese. PMID:29930650

Describe the process of cross-cultural adaptation of the "Explanatory Model Interview Catalog - Stigma Scale" for people affected by leprosy in Brazil. After being authorized by the author of the scale to use it in the national context, we initiated the five steps process of cross-cultural adaptation: (1) translation, (2) synthesis meeting, (3) back-translation, (4) committee of experts and (5) pre-test. The internal consistency of the scale was evaluated using Cronbach's alpha coefficient. The 15 items of the scale's original version were translated into Brazilian Portuguese. The adapted scale showed evidence of a good understanding of its content, attested both by experts and members of the target population. Its internal consistency was 0.64. The adapted instrument shows satisfactory internal consistency. It may be useful in future studies that intend to provide broad situational analysis that supports solid public health programs with a focus on effective stigma reduction. In a later study, the construct's validity, criterion, and reproducibility will be evaluated.

Following the AGILE detection of a non-identified gamma-ray source AGL J1412-0522 on 5-7 August 2017 (ATel #10623), we performed radio observations with the 32-m Medicina radio telescope at 8.5 GHz (with 680 MHz bandwidth) on 9 August 2017 from 12:40 to 19:00 UTC and on 10 August 2017 from 14:00 to 17:50 UTC. We carried out squared on-the-fly maps of 45.5'x45.5' centered on the gamma-ray position (ra=14:12:06.0, dec=-05:22:14.9) to take into account the 0.4 deg position error from AGILE results.

Shallow-water habitats as sources of fallback foods for hominins.

Underground storage organs (USOs) have been proposed as critical fallback foods for early hominins in savanna, but there has been little discussion as to which habitats would have been important sources of USOs. USOs consumed by hominins could have included both underwater and underground storage organs, i.e., from both aquatic and terrestrial habitats. Shallow aquatic habitats tend to offer high plant growth rates, high USO densities, and relatively continuous USO availability throughout the year. Baboons in the Okavango delta use aquatic USOs as a fallback food, and aquatic or semiaquatic USOs support high-density human populations in various parts of the world. As expected given fossilization requisites, the African early- to mid-Pleistocene shows an association of Homo and Paranthropus fossils with shallow-water and flooded habitats where high densities of plant-bearing USOs are likely to have occurred. Given that early hominins in the tropics lived in relatively dry habitats, while others occupied temperate latitudes, ripe, fleshy fruits of the type preferred by African apes would not normally have been available year round. We therefore suggest that water-associated USOs were likely to have been key fallback foods, and that dry-season access to aquatic habitats would have been an important predictor of hominin home range quality. This study differs from traditional savanna chimpanzee models of hominin origins by proposing that access to aquatic habitats was a necessary condition for adaptation to savanna habitats. It also raises the possibility that harvesting efficiency in shallow water promoted adaptations for habitual bipedality in early hominins.

Para a maioria dos estudantes, sua passagem pelo ensino formal fundamental envolve a transmissão de fatos que devem ser guardados para um exame, a habilidade para lembrar fórmulas e, eventualmente, a repetição de experimentos que devem produzir resultados exigidos pelo professor. O resultado deste modelo de ensino, ao longo dos anos, é conhecido por todos: desconhecimento e descontentamento, por parte dos estudantes, de temas relativos ao papel e aos processos da ciência. Acreditamos que a Astronomia, pelo seu caráter observacional, é uma das áreas do conhecimento que pode contribuir neste cenário. A Fundação Planetário da Cidade do Rio de Janeiro possui um telescópio Meade LX-200 (25cm) que, juntamente com as câmeras CCD ST-7E e ST8E, tem sido utilizado em projetos voltados aos estudantes do ensino médio desde o ano 2000. Tais projetos envolvem a condução de um projeto de pesquisa observacional num nível apropriado, e possibilitam o contato com técnicas e novas tecnologias: computador, software para manipulação de dados e gráficos, programas de tratamento e redução de dados, uso de equipamentos óptico-eletrônicos (telescópio e CCD), bem como o processo de aquisição de conhecimento. Dentro da proposta dos anos anteriores, priorizamos projetos de uma noite, ou seja, procuramos trabalhar com fenômenos que apresentem variabilidade com intervalo de recorrência relativamente curto. Em todos os casos, optamos pela fotometria diferencial, que tem se mostrado bastante eficiente para o céu luminoso como o da cidade do Rio de Janeiro. Neste painel, apresentamos alguns dos projetos desenvolvidos no último ano, com 25 estudantes. Apresentamos os resultados da observação da variável pulsante AI Vel (V = 6,6) e da variável cataclísmica FO Aqr (V = 13,5), e do monitoramento do trânsito da lua de Júpiter, Europa, ocorrido em 30 de abril de 2003. As curvas de luz produzidas para as primeiras estão concordantes com as da literatura, assim como os respectivos períodos encontrados (1h20min e 4h48min). No caso do FO Aqr, ficou evidente, também, a modulação decorrente da rotação da anã branca receptora (21min). O erro estimado é de 0,01 magnitude. Propomos uma maior utilização de telescópios de pequeno porte, como suporte ao ensino (médio e superior) em cidades com poluição luminosa. Escolas e Planetários seriam ambientes propícios para a localização do telescópio. Os critérios adotados na escolha dos objetos e o método observacional empregado são também apresentados.

To present a Metabolic Risk Score to better guide the surgical indication for T2DM patients with body mass index (BMI) where surgery for obesity is still controversial. Research was conducted in PubMed, Medline, PubMed Central, Scielo and Lilacs between 2003-2015 correlating headings: metabolic surgery, obesity and type 2 diabetesmellitus. In addition, representatives of the societiesinvolved, as an expert panel, issued opinions. Forty-five related articles were analyzed by evidence-based medicine criteria. Grouped opinions sought to answer the following questions: Why metabolic and not bariatric surgery?; Mechanisms involved in glycemic control; BMI as a single criterion for surgical indication for uncontrolled T2DM; Results of metabolic surgery studies in BMI<35 kg/m2; Safety of metabolic surgery in patients with BMI<35 kg/m2; Long-term effects of surgery in patients with baseline BMI<35 kg/m2 and Proposal for a Metabolic Risk Score. Metabolic surgery has well-defined mechanisms of action both in experimental and human studies. Gastrointestinal interventions in T2DM patients with IMC≤35 kg/m2 has similar safety and efficacy when compared to groups with greater BMIs, leading to the improvement of diabetes in a superior manner than clinical treatment and lifestyle changes, in part through weight loss independent mechanisms . There is no correlation between baseline BMI and weight loss in the long term with the success rate after any surgical treatment. Gastrointestinal surgery treatment may be an option for patients with T2DM without adequate clinical control, with a BMI between 30 and 35, after thorough evaluation following the parameters detailed in Metabolic Risk Score defined by the surgical societies. Roux-en-Y gastric bypass (RYGB), because of its well known safety and efficacy and longer follow-up studies, is the main surgical technique indicated for patients eligible for surgery through the Metabolic Risk Score. The vertical sleeve gastrectomy may be considered if there is an absolute contraindication for the RYGB. T2DM patients should be evaluated by the multiprofessional team that will assess surgical eligibility, preoperative work up, follow up and long term monitoring for micro and macrovascular complications. Mesmo considerando o avanço do tratamento clínico ocorrido nos últimos 20 anos, com novos e mais eficientes medicamentos, os dados ainda são desanimadores quanto ao controle da obesidade e da diabete melito tipo 2(DMT2),com grande parcela de doentes em tratamento clínico ficando fora da meta desejada de controle.

A cirurgia metabólica tem mecanismos de ação bem definidos tanto em estudos experimentais quanto em seres humanos. As intervenções gastrointestinais em diabéticos com IMC≤35 kg/m2 possuem segurança e eficácia semelhantes aos grupos com IMCs maiores, levando a melhora do diabete de forma superior aos tratamentos clínicos e mudanças de estilo de vida, em parte através de mecanismos independentes da perda ponderal. Não há correlação entre o IMC inicial e perda ponderal em longo prazo com os índices de sucesso do tratamento cirúrgico. O tratamento cirúrgico é opção para os pacientes portadores de DMT2 sem adequado controle clínico, com IMC entre 30 e 35, após minuciosa avaliação seguindo os parâmetros dispostos no Escore de Risco Metabólico aqui proposto.

Doctors and pharmacies in the 15th Century only used handwritten copies of the prescription collections available in their time. At the beginning of book printing the publishing of prescription collections immediately became popular. They could be found on the pages of medical and pharmaceutical books of many various editions with different structure and origin, as the forerunner of the official pharmacopoeias. From the 16th Century onwards books with the title "Medicina Pauperum" were published which helped the educated people to tend to themselves, the household, the servants and their immediate surroundings case of an illness. The first work specifically on the topic or of genre of the "Medicina Pauperum" according to our knowledge appeared in Hungarian in the year 1660 and currently seems to survived only in fragments under the title of "Medicina Pauperum", from an unknown author. A rare incident occurred in the present days as a "book" believed to be lost for us turned up from thin air. It is a "copied" manuscript in the size of 97×139 mm attached to the ribs with hemp cord, cropped around and in an unbound state. The book known before only in fractions is now available entirety handwritten on 318 pages, distributed to seven distinct parts. The research of its origin suggests that the author lived and worked in Nagyszombat and was called Johann Misch Astrophilus. The identification of the printing office was possible thanks to the examination of the initials and the gaudily, as well as the fonts and the watermark. By these results the printing very likely occurred in the Brewer Printing Press in Lőcse. For the possibility of more extensive research and value preservation the manuscript was bounded. The facsimile edition contains the magnified and digitalized pages of the original one and is published in numbered issues.

Analysis of South Atlantic Anomaly perturbations on Sentinel-3A Ultra Stable Oscillator. Impact on DORIS phase measurement and DORIS station positioning

NASA Astrophysics Data System (ADS)

Jalabert, Eva; Mercier, Flavien

2018-07-01

DORIS measurements rely on the precise knowledge of the embedded oscillator which is called the Ultra Stable Oscillator (DORIS USO). The important radiations in the South Atlantic Anomaly (SAA) perturb the USO behavior by causing rapid frequency variations when the satellite is flying through the SAA. These variations are not taken into account in standard DORIS processing, since the USO is modelled as a third degree polynomial over 7-10 days. Therefore, there are systematic measurements errors when the satellite passes through SAA. In standard GNSS processing, the clock is directly estimated at each epoch. On Sentinel-3A, the GPS receiver and the DORIS receiver use the same USO. It is thus possible to estimate the behavior of the USO using GPS measurements. This estimated USO behavior can be used in the DORIS processing, instead of the third degree polynomial, hence allowing an estimation of the orbit sensitivity to these USO anomalies. This study shows two main results. First, the SAA effect on the DORIS USO is observed well using GPS measurements. Second, the USO behavior observed with GPS can be used to mitigate the SAA effect. Indeed, when used in Sentinel-3A processing, the resulting DORIS orbit shows improved phase measurements and station positioning for stations inside the SAA (Arequipa and Cachoeira). The phase measurements residuals are improved by up to 10 cm, and station vertical positioning (i.e. on the estimated Up component in the North-East-Up station frame) is improved by up to a few centimeters. However, the orbit itself is not sensitive to the correction because only two stations (out of almost 60) are SAA-sensitive on Sentinel-3A.

Melhoramentos no código Wilson-Devinney para binárias eclipsantes

A análise de curvas de luz e velocidades radiais de sistemas binários eclipsantes pode ser feita por meio de vários modelos. Um desses é o Modelo Wilson-Devinney (WD). Ao longo dos anos, esse modelo sofreu várias alterações em seus códigos principais, com a finalidade de torná-lo mais consistente tanto fíisica como numericamente. O Modelo WD tem sido melhorado de várias maneiras em seus dois códigos: um para a predição das curvas de luz teórica e de velocidade radiais e outra para as soluções destas curvas. Teoricamente, na física do modelo, nós introduzimos a possibilidade de levar em conta os efeitos do movimento apsidal. Numericamente, nós introduzimos a possibilidade de usar o Método SIMPLEX no procedimento da solução, como uma alternativa para o já implementado Método de Mínimos Quadrados (Least Squares Method). Estas modificações, juntamente com outras já introduzidas pelo nosso grupo anteriormente, tornam o código mais eficiente na solução das curvas de luz e de velocidade radiais de binárias eclipsantes. Como o modelo tem sido usado para analisar sistemas com componentes pré-sequência principal (TY CrA, Casey et al. 1998, Vaz et al. 1998), SM 790, Stassun et al. 2003), este melhoramento beneficiará estes casos também. Apresentamos os resultados obtidos com a modificação do código WD por meio do uso de dados da estrela GL Carinae, comprovando, (1) que os parâmetros orbitais calculados por nós são coerentes com os obtidos anteriormente na literatura (Giménez & Clausen, 1986) e com os obtidos por Faria (1987), e (2) que a implementação do Método SIMPLEX torna o código mais lento mas completamente consistente internamente e evita os problemas gerados pelo uso do Método de Mínimos Quadrados, tais como imprecisão no cálculo das derivadas parciais e convergência para mínimos locais.

The scientific authorship of Doctor Chernoviz, from the popularization of medicine to professional training: the Dicionário de medicina popular, 1842-1890.

This article reflects on the scientific authorship of Pedro Luiz Napoleão Chernoviz, based on his Dicionário de medicina popular, which was published in six editions between 1842 and 1890. The first part of the text discusses Chernoviz's position within the regimes of scientific authorship which were present in the medical community in Rio de Janeiro. Next, we analyze the author's arguments justifying a text that popularized medical science while this field strove for exclusivity in the practice of medicine. Finally, we suggest new meanings around Chernoviz's scientific authorship based on how the Dicionário was used and read by an initiated public.

In this study, we evaluated the psychometric properties of the items to measure the work-family conflict and the time use for personal care and leisure, included in the baseline questionnaire of the Longitudinal Study of Adult Health (ELSA-Brazil). We evaluated temporal stability (7-14 days) using kappa statistic and the validity of the construct by the correlation of Kendall's tau with other variables. Test-retest stability was discreet to moderate and the correlations were compatible with the underlying theory. Future studies in the context of ELSA-Brazil and in other populations will complement the assessment of its relevance. RESUMO Neste estudo, avaliamos as propriedades psicométricas dos itens para mensurar o conflito trabalho-família e o uso do tempo para cuidado pessoal e lazer, incluídos no questionário da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Foram avaliadas a estabilidade temporal (7-14 dias) utilizando estatística kappa e a validade do construto pela correlação tau de Kendall com outras variáveis. A estabilidade teste-reteste foi discreta a moderada e as correlações, compatíveis com a teoria subjacente. Estudos futuros no contexto do ELSA-Brasil e em outras populações complementarão a avaliação da sua pertinência.

To provide an update on trends in asthma mortality in Brazil for two age groups: 0-4 years and 5-34 years. Data on mortality from asthma, as defined in the International Classification of Diseases, were obtained for the 1980-2014 period from the Mortality Database maintained by the Information Technology Department of the Brazilian Unified Health Care System. To analyze time trends in standardized asthma mortality rates, we conducted an ecological time-series study, using regression models for the 0- to 4-year and 5- to 34-year age groups. There was a linear trend toward a decrease in asthma mortality in both age groups, whereas there was a third-order polynomial fit in the general population. Although asthma mortality showed a consistent, linear decrease in individuals ≤ 34 years of age, the rate of decline was greater in the 0- to 4-year age group. The 5- to 34-year group also showed a linear decline in mortality, and the rate of that decline increased after the year 2004, when treatment with inhaled corticosteroids became more widely available. The linear decrease in asthma mortality found in both age groups contrasts with the nonlinear trend observed in the general population of Brazil. The introduction of inhaled corticosteroid use through public policies to control asthma coincided with a significant decrease in asthma mortality rates in both subsets of individuals over 5 years of age. The causes of this decline in asthma-related mortality in younger age groups continue to constitute a matter of debate. Apresentar uma atualização das tendências da mortalidade da asma no Brasil em duas faixas etárias: 0-4 anos e 5-34 anos. Dados relativos ao período de 1980 a 2014 referentes à mortalidade da asma, conforme se definiu na Classificação Internacional de Doenças, foram extraídos Sistema de Informação sobre Mortalidade do Departamento de Tecnologia da Informação do Sistema Único de Saúde. Para analisar as tendências temporais das taxas padronizadas de mortalidade da asma, realizou-se um estudo ecológico de séries temporais com modelos de regressão para as faixas etárias de 0 a 4 anos e 5 a 34 anos. Houve uma tendência linear de redução da mortalidade da asma em ambas as faixas etárias e uma tendência polinomial de terceira ordem na população geral. Embora a mortalidade da asma tenha apresentado redução linear consistente em indivíduos com idade ≤ 34 anos, a taxa de declínio foi maior na faixa etária de 0 a 4 anos. A faixa etária de 5 a 34 anos também apresentou redução linear da mortalidade, e essa redução tornou-se mais pronunciada após o ano de 2004, quando o tratamento com corticosteroides inalatórios tornou-se mais amplamente disponível. A redução linear da mortalidade da asma em ambas as faixas etárias contrasta com a tendência não linear observada na população geral do Brasil. A introdução do uso de corticosteroides inalatórios por meio de políticas públicas de controle da asma coincidiu com uma diminuição significativa das taxas de mortalidade da asma em ambos os subgrupos de indivíduos com mais de 5 anos de idade. As causas dessa redução da mortalidade da asma em faixas etárias mais jovens ainda são objeto de debate.

to identify the effect of the mental, physical, temporal, performance, total effort and frustration demands in the overall workload, and in the same way analyze the global burden of port labor and associated factors that contribute most to their decrease or increase. a cross-sectional, quantitative study, developed with 232 dock workers. For data collection, a structured questionnaire with descriptive, occupational, smoking and illicit drug use variables was applied, as well as variables on the load on the tasks undertaken at work, based on the questionnaire NASA Task Load Index. For data analysis, we used the analysis of the Poisson regression model. the demands physical demand and total effort showed greater effect on the overall workload, indicating high overall load on port work (134 employees - 58.8%). The following remained associated statistically with high levels of workload: age (p = 0.044), to be employee of the wharfage (p = 0.006), work only at night (p = 0.025), smoking (p = 0.037) and use of illegal drugs (p = 0.029). the workload in this type of activity was high, and the professional category and work shift the factors that contributed to the increase, while the age proved to be a factor associated with a decrease. identificar o efeito das demandas mental, física, temporal, de desempenho, esforço total e frustração na carga global de trabalho, da mesma maneira que analisar a carga global de trabalho portuário e fatores associados que mais contribuem para sua diminuição ou aumento. estudo transversal, quantitativo, desenvolvido com 232 trabalhadores portuários.

To understand the meanings assigned by long-distance truck drivers to HIV/AIDS and its transmission and prevention, bearing in mind different contexts of vulnerability. Qualitative research with 22 truck drivers. Semi-structured interviews and participant observation were conducted in highways of the state of Bahia in 2013. We selected male truck drivers, with one year or more of work experience in long-distance routes. We carried out the thematic analysis of the interviews, to identify different contexts of vulnerability. The results showed that the insertion of truck drivers in contexts of high social vulnerability (poor working conditions, violence on the roads, and use of alcohol and other drugs) along with the advances in access and effectiveness of treatment for AIDS promote a reduced perception of the risk and severity of this disease. In addition, the notion of "risk group" and the symbolic division between "home space" (protected) and "street space" (unprotected) intensified a restricted and specific use of condoms, guided by the opposition between "woman of the street" (unknown women, prostitutes, among others) and "woman of the house" (wives, girlfriends). The meanings assigned by truckers to AIDS incorporated elements of recent transformations of the expanded social context, such as the development of health technologies (especially anti-retroviral drugs) and the guarantee of free access to treatment in the Brazilian public health system; but also incorporated old elements of social vulnerability context - such as the poor working conditions on Brazilian highways. Compreender os significados atribuídos pelos caminhoneiros de rota longa ao HIV/aids e à sua transmissão e prevenção, tendo em vista diferentes contextos de vulnerabilidade. Pesquisa qualitativa com 22 caminhoneiros. Foram realizadas entrevistas semi-estruturadas e observação participante em rodovias do estado da Bahia em 2013. Foram selecionados caminhoneiros do sexo masculino, com um ano ou mais de experiência de trabalho em rotas de longa distância. Realizou-se análise temática das entrevistas, orientada para identificação de diferentes contextos de vulnerabilidade. Os resultados mostraram que a inserção dos caminhoneiros em contextos de alta vulnerabilidade social (más condições de trabalho, violência nas estradas e uso de álcool e outras drogas) e os avanços no acesso e efetividade do tratamento para aids favorecem a minimização da percepção de risco e gravidade dessa doença. Além disso, a noção de "grupo de risco" e a divisão simbólica entre "espaço da casa" (protegido) e "espaço da rua" (desprotegido) intensificaram um uso restrito e específico do preservativo, orientado pela oposição entre "mulher do mundo" (desconhecidas, prostitutas, entre outros) e "mulher de casa" (esposas, namoradas). Os significados atribuídos pelos caminhoneiros à aids incorporaram elementos de transformações recentes do contexto social ampliado, como o desenvolvimento de tecnologias em saúde (com destaque para os antirretrovirais) e a garantia de acesso gratuito ao tratamento no sistema público de saúde no Brasil; mas também incorporaram antigos elementos do contexto de vulnerabilidade social - a exemplo das más condições de trabalho nas estradas brasileiras.

Tavares, E. T., Jr.; Klafke, J. C.

2003-08-01

O presente trabalho propõe-se a resgatar uma experiência que teve lugar no Planetário de São Paulo nos anos 60. Em 1962, o Sr. Acácio, então com 37 anos, deficiente visual desde os 27, passou a assistir às aulas ministradas pelo Prof. Aristóteles Orsini aos integrantes do corpo de servidores do Planetário. O Sr. Acácio era o único deficiente da turma e, embora possuísse conhecimentos básicos e relativamente avançados de matemática, enfrentava dificuldades na compreensão e acompanhamento da exposição, como também em estudos posteriores. Com o intuito de auxiliá-lo na superação desses problemas, o Prof. Orsini solicitou a construção de modelos mecânicos que, através do sentido do tato, permitissem o acompanhamento das aulas e a transposição do modelo para o "constructo" mental. Essa prática mostrou-se tão eficaz que facilitou sobejamente o aprendizado da matéria pelo sujeito. O Sr. Acácio passou a integrar o corpo de professores do Planetário/Escola Municipal de Astrofísica, tendo ficado responsável pelo curso de "Introdução à Astronomia" por vários anos. Além disso, a experiência foi tão bem sucedida que alguns dos modelos tiveram seus elementos constitutivos pintados diferencialmente para serem utilizados em cursos regulares do Planetário, tornando-se parte integrante do conjunto de recursos didáticos da instituição. É pensando nessa eficácia, tanto em seu objetivo original permitir o aprendizado de um deficiente visual quanto no subsidiário recurso didático sistemático da instituição que decidimos resgatar essa experiência. Estribados nela, acreditamos ser extremamente produtivo, em termos educacionais, o aperfeiçoamento dos modelos originais, agora resgatados e restaurados, e a criação de outros que pudessem ser utilizados no ensino dessa ciência a deficientes visuais.

To identify the incidence of delirium, compare the demographic and clinical characteristics of patients with and without delirium, and verify factors related to delirium in critical care patients. Prospective cohort with a sample made up of patients hospitalized in the Intensive Care Unit (ICU) of a university hospital. Demographic, clinical variables and evaluation with the Confusion Assessment Method for Intensive Care Unit to identify delirium were processed to the univariate analysis and logistic regression to identify factors related to the occurrence of delirium. Of the total 149 patients in the sample, 69 (46.3%) presented delirium during ICU stay, whose mean age, severity of illness and length of ICU stay were statistically higher. The factors related to delirium were: age, midazolam, morphine and propofol. Results showed high incidence of ICU delirium associated with older age, use of sedatives and analgesics, emphasizing the need for relevant nursing care to prevent and identify early, patients presenting these characteristics. Identificar a incidência de delirium, comparar as características demográficas e clínicas dos pacientes com e sem delirium e verificar os fatores relacionados ao delirium em pacientes internados em Unidade de Terapia Intensiva (UTI).

This article aims to identify the relational technologies used by Family Health Strategy nurses in their daily work when treating patients. Descriptive and cross-sectional study with qualitative approach; conducted between May and July 2015, in three Basic Health Units of the Southern Region of the Municipality of São Paulo, with 19 nurses of the Family Health Strategy. Data were collected through a semi-structured interview, and the speeches were fully transcribed and analyzed according to the technique of content analysis. From the speeches of the participants, three categories emerged, showing the unawareness of the concept, but the valorization of its use; which are the relational technologies used by the participating nurses (communication, listening, empathy and welcoming reception), as well as the report of barriers to the use of relational technologies. Although the nurses value the use of relational technologies, the participants denoted unawareness of the nomenclature and its associated concepts, suggesting superficiality in the understanding and use of these instruments in the context of care in the Family Health Strategy. Identificar as tecnologias relacionais utilizadas por enfermeiros de Estratégia Saúde da Família em seu cotidiano de trabalho no atendimento aos usuários. Estudo descritivo, transversal, com abordagem qualitativa; desenvolvido entre maio e julho de 2015, em três Unidades Básicas de Saúde da Região Sul do Município de São Paulo, com 19 enfermeiros da Estratégia Saúde da Família. Os dados foram coletados por meio de entrevista semiestruturada, e os discursos foram transcritos na íntegra, analisados segundo a técnica de análise de conteúdo. Das falas dos participantes, surgiram três categorias, que evidenciam o desconhecimento do conceito, mas valorização do uso; quais são as tecnologias relacionais utilizadas pelos enfermeiros participantes (comunicação, escuta, empatia e acolhimento), além do relato de barreiras para a utilização de tecnologias relacionais. Embora valorizem a utilização de tecnologias relacionais, os participantes denotaram desconhecer a nomenclatura e os conceitos associados, sugerindo superficialidade na compreensão e utilização dessas ferramentas no contexto de atendimento na Estratégia Saúde da Família.

Descriptive and analytical statistical analyses were performed. average patient age was 56.96 and 51.5% of the sample population was male. The incidence of phlebitis was 1.25% while using PIC, and 1.38% post-infusion. The incidence of phlebitis while using PIC was associated with the length of time the catheter remained in place, whereas post-infusion phlebitis was associated with puncture in the forearm. Ceftriaxone, Clarithromycin and Oxacillin are associated with post-infusion phlebitis. this study made it possible to investigate the association between risk factors and phlebitis during catheter use and following its removal. The frequency of post-infusion phlebitis was larger than the incidence of phlebitis with the catheter in place, with Phlebitis Grade III and II being the most frequently found in each of these situations, respectively. Aspects related to post-infusion phlebitis can be explained, given the limited number of studies addressing this theme from this perspective. investigar a incidência de flebites e a associação de fatores de risco com a sua ocorrência durante o uso e após a retirada do cateter intravenoso periférico - CIP (Flebite pós-infusão) em adultos hospitalizados. estudo de coorte com 171 pacientes com CIP, totalizando 361 punções. Foram coletadas variáveis sociodemográficas e relacionadas ao cateter. Análise estatística descritiva e analítica. dos pacientes, 51,5% eram homens e a média de idade foi de 56,96 anos. A incidência de flebites durante o uso do CIP foi de 1,25% e a pós-infusão foi de 1,38%. Associou-se à flebite durante o uso do CIP ao tempo de permanência do cateter e, com a flebite pós-infusão, a punção em antebraço. Os medicamentos Ceftriaxona, Claritromicina e Oxacilina foram associados à flebite pós-infusão. este estudo possibilitou investigar a associação de fatores de risco e a ocorrência de flebites durante o uso e após a retirada do cateter. A frequência da flebite pós-infusão foi maior do que o número de flebites durante a permanência do cateter, sendo as de grau III e II, respectivamente, as mais frequentes. Podem ser elucidados aspectos relacionados à flebite pós-infusão, considerando-se poucos estudos abordam o tema sob esta perspectiva. investigar la incidencia de flebitis y la asociación de factores de riesgo con su ocurrencia durante el uso y después de la retirada del catéter intravenoso periférico (CIP) (flebitis post-infusión) en adultos hospitalizados. estudio de cohorte con 171 pacientes con CIP, totalizando 361 punciones.

Atrial fibrillation (AF) is a common arrhythmia, with risk of systemic embolism and death. It presents rheumatic etiology in up to 32% of developing countries, whose anticoagulation and evolution data are scarce. to determine the predictors of cardiac death considering the clinical profile, thromboembolism and bleeding scores of patients with AF of a single center, with high prevalence of rheumatic heart disease. 302 patients with AF were studied, mean age 58.1 years; 161 women; 96 pts with rheumatic etiology. Patients underwent clinical and laboratory evaluation, measurement of risk scores and the mean follow-up of 12.8 months. 174 were using warfarin. The averages of the HAS-BLED and ATRIA scores were 1.4 and 1.2, respectively. Percent time in therapeutic range of international normalized ratio was 45.8%. Thirty patients (9.9%) had cardiac death and 41 had some type of bleeding due to warfarin. By univariate analysis, there was statistical significance between cardiac death and permanent AF, blood pressure, systolic dysfunction, R2CHADS2, CCS, EHRA and HAS-BLED. There was no association with valvular AF. By multivariate analysis, systemic arterial and pulmonary artery pressures, classification CCS and systolic dysfunction showed statistical significance. There was no association between cardiac death and valvular AF. Independent predictors of cardiac death were low measures of blood pressure, higher score CCS classification and the presence of systolic ventricular dysfunction. A fibrilação atrial (FA) é uma arritmia comum, com risco de embolia sistêmica e morte. Apresenta etiologia reumática em até 32% dos países em desenvolvimento, cujos dados de anticoagulação e evolução são escassos. Verificar as variáveis preditoras de morte cardíaca (MC) conforme o perfil clínico, os escores de tromboembolismo e de sangramento dos pacientes com FA de uma única instituição universitária, com alta prevalência de cardiopatia reumática. Foram estudados 302 pts com FA, média de idade 58,1 anos; 161 mulheres; 96 pts com etiologia reumática. Os pts foram submetidos à avaliação clínica e laboratorial, ao cálculo dos escores de risco e ao seguimento clínico médio de 12,8 meses. 174 pts estavam em uso de varfarina. As médias dos escores HAS-BLED e ATRIA foram de 1,4 e de 1,2, respectivamente. O cálculo da fração dos valores da razão normalizada internacional dentro do intervalo terapêutico foi de 45,8%. Houve MC em 30 pts (9,9%) e 41 apresentaram algum tipo de hemorragia em decorrência do uso de varfarina. Pela análise univariada, houve significância estatística entre MC e FA permanente, pressões arteriais, disfunção sistólica, R2CHADS2, CCS, EHRA e HAS-BLED. Não houve associação com FA valvar. Por meio da análise multivariada, a pressão arterial sistêmica e da artéria pulmonar, a classificação CCS e a disfunção sistólica apresentavam significância estatística. Não houve associação entre MC e FA valvar. Os preditores independentes de MC foram medidas baixas de pressão arterial, escores mais elevados da classificação CCS e a presença de disfunção ventricular sistólica.

Bariatric surgery is deemed one of the most effective procedures for the treatment of obesity and it aims at the reduction and maintenance of weight loss in long term, as the control of the related comorbidities. Quantify the occurrence of alterations of the gastrointestinal tract, suggestive signs of nutritional deficiencies and the use of supplements in a group of women undergoing bariatric surgery. The sample consisted of women aged 20-65 years submitted to Roux-en-Y gastric bypass with monitoring equal to or higher than 24 months. For the qualitative analysis, the Feeding Frequency Questionnaire was used. In the postoperative period, alopecia was the most reported (79.3%), followed by changes in the texture of the nails, both considered predictive of nutritional deficiencies. Changes in the gastrointestinal tract were described in 86.2%, and episodes of dumping were reported in 65.5%. Qualitative analysis has shown reduced daily consumption of sources of animal and plant proteins. After bariatric surgery can occur flatulence, vomiting and dumping syndrome as the most frequent representative symptoms of digestive functional disorders. Alopecia and nail changes are the most important signs of nutritional deficiency. The use of dietary supplements in the postoperative period is scarce and sporadic. A cirurgia bariátrica é considerada um dos procedimentos mais eficazes para tratamento da obesidade e objetiva a redução e manutenção da perda de peso em longo prazo, assim como, o controle das comorbidades associadas. Quantificar a ocorrência de alterações funcionais do trato gastrointestinal, sinais sugestivos de carências nutricionais e o uso de suplementos em um grupo de mulheres submetidas à cirurgia bariátrica. A amostra foi constituída por mulheres com idades entre 20-65 anos submetidas ao bypass gástrico em Y-de-Roux com seguimento igual ou superior a 24 meses. Para análise qualitativa foi utilizado o Questionário de Frequência Alimentar. No período pós-operatório a alopecia foi a mais relatada (79,3%), seguida de alteração na textura das unhas, ambas consideradas preditivos de carências nutricionais. As alterações do trato gastrointestinal foram descritas por 86,2%, e os episódios de dumping foram relatados em 65,5%. Na análise qualitativa foi observado consumo diário reduzido de fontes de proteínas animal e vegetal. Após a cirurgia bariátrica pode ocorrer flatulência, vômitos e síndrome de dumping como sintomas representativos mais frequentes das alterações funcionais digestivas. Alopecia e alterações ungueais são os sinais mais relevantes de carência nutricional. O uso de suplementos alimentares no pós-operatório é escasso e esporádico.

Espectros sintéticos são utéis em uma grande variedade de aplicações, desde análise de abundâncias em espectros estelares de alta resolução ao estudo de populações estelares em espectros integrados. A confiabilidade de um espectro sintético depende do modelo de atmosfera adotado, do código de formação de linhas e da qualidade dos dados atômicos e moleculares que são determinantes no cálculo das opacidades da fotosfera. O nosso grupo no departamento de Astronomia no IAG tem utilizado espectros sintéticos há mais de 15 anos, em aplicações voltadas principalmente para a análise de abundâncias de estrelas G, K e M e populações estelares velhas. Ao longo desse tempo, as listas de linhas vieram sendo construídas e atualizadas continuamente, e alguns acréscimos recentes podem ser citados: Castilho (1999, átomos e moléculas no UV), Schiavon (1998, bandas moleculares de TiO) e Melendez (2001, átomos e moléculas no IV próximo). Com o intuito de calcular uma grade de espectros do UV ao IV próximo para uso no estudo de populações estelares velhas, se fazia necessário compilar e homogeneizar as diversas listas em apenas uma lista atômica e uma molecular. Nesse processo, a nova lista compilada foi correlacionada com outras bases de dados (NIST, Kurucz Database, O' Brian et al. 1991) para atualização dos parâmetros que caracterizam a transição atômica (comprimento de onda, log gf e potencial de excitação). Adicionalmente as constantes de interação C6 foram calculadas segundo a teoria de Anstee & O'Mara (1995) e artigos posteriores. As bandas moleculares de CH e CN foram recalculadas com o programa LIFBASE (Luque & Crosley 1999). Nesse poster estão detalhados os procedimentos citados acima, as comparações entre espectros calculados com as novas listas e espectros observados em alta resolução do Sol e de Arcturus, e uma análise do impacto decorrente da utilização de diferentes modelos de atmosfera no espectro sintético. Ao final, temos uma lista de linhas atômicas com mais de 24.000 linhas e uma lista molecular com as moléculas CN, CH, OH, NH, MgH, C2, TiO Gama, CO, FeH, adequadas ao estudo de estrelas G, K e M e populações estelares velhas.

to assessed the prevalence of diabetes mellitus (DM) and drug abuse in mothers of children with orofacial clefts (OFC). 325 women who had children (0-3y) with clefts were interviewed. Data regarding type of diabetes, use of legal/illegal drugs during pregnancy, waist girth and fasting blood sugar at the first prenatal consult were collected. twenty seven percent of the women had DM, out of these, 89% had gestational DM, 5,5% type 1 DM and 5,5% type 2 DM. The prevalence of DM in mothers of children with OFC was 27%, it is significantly higher than the average Brazilian population which is 7.6% (p<0.01) (OR=4.5, 95%CI=3.5-5.8). Regarding drug abuse during pregnancy, 32% of the mothers used drugs and a significant positive correlation was observed between drug abuse and the occurrence of clefts and other craniofacial anomalies (p=0.028) (OR=2.87; 95%CI=1.1-7.4). DM and drug abuse during pregnancy increases the risk for OFC and related anomalies and early diagnosis of DM and prevention of drug abuse, especially in pregnant women, should be emphasized. esta investigación estableció la prevalencia de diabetes mellitus (DM) y el abuso de drogas en madres de niños con malformaciones creaneofaciales (MCF). 325 mujeres que tuvieron hijos (0-3 años) con malformaciones fueron entrevistadas.

to evaluate problems associated with alcohol use among university students who reported binge drinking in comparison to students who consumed alcohol without binging. a cross-sectional study among university students (N=2,408) who accessed the website about alcohol use. Logistic and linear regression models were included in the statistical analyzes. alcohol use in the last three months was reported by 89.2% of university students; 51.6% reported binge drinking. Compared to students who did not binge drink, university students who presented this pattern were more likely to report all evaluated problems, among them: black out (aOR: 5.4); having academic problems (aOR: 3.4); acting impulsively and having regrets (aOR: 2.9); getting involved in fights (aOR: 2.6); drinking and driving (aOR: 2.6) and accepting a ride with someone who had drunk alcohol (aOR: 1.8). Students who binged also had higher scores on the Alcohol Use Disorders Identification Test (b=4.6; p<0.001), more negative consequences (b=1.0; p<0.001) and a reduced perception of the negativity of the consequences (b=-0.5; p<0.01). binge drinking was associated with an increase in the chances of manifesting problems related to alcohol use. The conclusions of this study cannot be generalized for all of the Brazilian population. avaliar problemas associados ao uso de álcool entre universitários que relataram binge drinking em comparação a estudantes que consumiram álcool sem binge drinking. estudo transversal entre universitários (N=2.408) que acessaram website sobre o uso de álcool.

The article analyzes conflicts and interests at one of Rio Grande de Sul's main centers for medical science, the Faculdade de Medicina de Porto Alegre. It explores the meaning and impact of the emergence of this specific, exclusive field of knowledge in a state where positivist principles of professional freedom were adopted by successive administrations during the early period of the Republic. Physicians there launched an entrenched war to uphold the principles of science over faith and politics, challenging the positivism of the party which held power in Rio Grande do Sul throughout the years. This perspective grew and developed in a climate of conflict and doubts among physicians, within a political context that differed from the rest of Brazil.

In radio astronomy Field Programmable Gate Array (FPGA) technology is largely used for the implementation of digital signal processing techniques applied to antenna arrays. This is mainly due to the good trade-off among computing resources, power consumption and cost offered by FPGA chip compared to other technologies like ASIC, GPU and CPU. In the last years several digital backend systems based on such devices have been developed at the Medicina radio astronomical station (INAF-IRA, Bologna, Italy). Instruments like FX correlator, direct imager, beamformer, multi-beam system have been successfully designed and realized on CASPER (Collaboration for Astronomy Signal Processing and Electronics Research, https://casper.berkeley.edu) processing boards. In this paper we present the gained experience in this kind of applications.

Resumo Contexto Os cateteres venosos centrais de inserção periférica (PICC) são dispositivos intravenosos, introduzidos através de uma veia superficial ou profunda da extremidade superior ou inferior até o terço distal da veia cava superior ou proximal da veia cava inferior. Apresentam maior segurança para infusão de soluções vesicantes/irritantes e hiperosmolares, antibioticoterapia, nutrição parenteral prolongada (NPT) e uso de quimioterápicos; demonstram reduzido risco de infecção em comparação a outros cateteres vasculares e maior relação custo/benefício se comparados ao cateter venoso de inserção central (CVCIC). Objetivos Apresentar os resultados de implantes de PICCs ecoguiados e posicionados por fluoroscopia realizados no Hospital e Maternidade São Luiz (HMSL) Itaim, Rede D’or, Brasil. Métodos Estudo prospectivo, não randomizado, realizado entre fevereiro de 2015 e novembro de 2016. Utilizou-se protocolo pré-estabelecido pela instituição em casos de solicitação de acesso vascular. Foram analisadas indicações, doenças prevalentes, tipo do cateter implantado, sucesso técnico, complicações relacionadas ao cateter, e estabelecidos critérios de inclusão e exclusão. Resultados Solicitados 256 acessos vasculares, sendo implantados 236 PICCs (92,1%) e 20 CVCICs (7,9%). Principais indicações: antibioticoterapia prolongada (52,0%), NPT (19,3%) e acesso venoso difícil (16,0%). Houve sucesso técnico em 246 cateteres implantados (96,1%). A veia basílica direita foi a principal veia puncionada em 192 pacientes (75,0%), seguida da braquial direita em 28 pacientes (10,9%). Conclusões O implante dos PICCs ecoguiados e posicionados por fluoroscopia demonstrou baixa incidência de complicações, reduzidos índices de infecção e é seguro e eficaz em casos de acessos vasculares difíceis, sendo esses cateteres considerados dispositivos de escolha em acesso vascular central.

This work developed at the Planetarium of Pará employing workshops designed for visitor schools (public, private, specials groups), promotes the popularization of the Ethnoastronomy with the aim of diffusing values based on a cultural diversity tolerance and the need of harmonic interplay between people and environment. Using stories and debates, the relationship between humans and the Cosmos is traced from antiquity until today, with the help of slides as a didactic resource. Thus, many conceptions about the origin of the Universe are shown; as well as some constellations created along the History, ending with the present scientific manner of know and explain the World. We then demonstrate the links between space, time and culture with the Cosmos vision. The need to think the World within a plural context to create respect for other different persons is emphasized. Este trabalho, desenvolvido no Planetário do Pará através de oficinas com escolas visitantes (públicas, privadas e grupos especiais), promove a popularização da Etnoastronomia, com o objetivo de difundir valores pautados na tolerância à diversidade cultural e na necessidade da convivência harmônica entre o ser humano e o meio ambiente. Através da contação de histórias e promoção de debate, é tratada a relação dos humanos com o céu desde a antiguidade até os dias atuais, tendo como apoio didático o uso de slides. Assim, são mostradas diversas concepções de origem do Universo; algumas constelações criadas no decorrer da História; e a atual forma científica de conhecer e explicar o mundo. Demonstrando-se, então, a interligação entre espaço, tempo e cultura com a visão do Cosmo. Enfatiza-se a necessidade de se pensar o mundo numa perspectiva relativa ou plural, de forma a propiciar o respeito ao ser diferente.

The Helicobacter pylori infection (HP) is related to the development of gastric lesions and lymphoma; however, it is not known if there is a relation with gastroesophageal reflux disease and reflux esophagitis. To evaluate HP's relationship with esophagitis in patients undergoing upper endoscopy. Observational, retrospective and cross-sectional study, being evaluated 9576 patients undergoing outpatient endoscopic examination during the period between January and December 2015. Were included patients with any esophageal alteration at the examination; greater than 18; of both genders; independent of the complaint or the reason for the examination, illness or drug use. Were excluded those with active bleeding during the examination and in use of anticoagulants. The variables gender, age, esophagitis and result of the urease test, were studied. For statistical analysis was used the Epi Info software 7.1.5.2. Most of the samples consisted of women and the overall average age was 46.54±16.32 years. The presence of infection was balanced for gender: 1204 (12.56%) women and 952 (13.92%) men. Relating degree of esophagitis HP- and HP+ was observed that the type A was the most common (58.79%, n=1460); 604 (24.32%) had grade B; 334 (13.45%) grade C, and 85 (3.42%) grade D. In the relation between the grade of esophagitis with gender, esophagitis A was predominant in women and present in 929 (63.33%), followed by type B, 282 (46.68%), 136 C (40.71%) and D 30 (35.29%). In men 531 (36.36%) showed type A, 322 (53.31%) B, 198 (59.28%) C, and 55 (64.70%) D. Among the groups 40-50 and over 60 years there was a significant difference in whether have or not have HP+. There is no significant difference between HP infection and the different grades of esophagitis.

To know the ways and means of comfort perceived by the older adults hospitalized in a medical service. Ethnographic study with a qualitative approach. We conducted semi-structured interviews with 22 older adults and participant observation of care situations. The ways and means of providing comfort are centered on strategies for promoting care mobilized by nurses and recognized by patients(clarifying/informing, positive interaction/communication, music therapy, touch, smile, unconditional presence, empathy/proximity relationship, integrating the older adult or the family as partner in the care, relief of discomfort through massage/mobilization/therapy) and on particular moments of comfort (the first contact, the moment of personal hygiene, and the visit of the family), which constitute the foundation of care/comfort. Geriatric care is built on the relationship that is established and complete with meaning, and is based on the meeting/interaction between the actors under the influence of the context in which they are inserted. The different ways and means of providing comfort aim to facilitate/increase care, relieve discomfort and/or invest in potential comfort. Conhecer os modos e formas de confortar percecionadas pelos idosos hospitalizados num serviço de medicina. Estudo etnográfico com abordagem qualitativa. Realizamos entrevistas semiestruturadas com 22 doentes idosos e observação participante nas situações de cuidados. Os modos e formas de confortar centram-se em estratégias promotoras de conforto mobilizadas pelo enfermeiro e reconhecidas pelos doentes (informação/esclarecimento, interação/comunicação positiva, toque, sorriso, presença incondicional, integração do idoso/família nos cuidados e o alívio de desconfortos através da massagem/mobilização/terapêutica) e em momentos particulares de conforto (contato inaugural, visita da família., cuidados de higiene e arranjo pessoal), que se constituem como alicerces do cuidar/cuidado confortador. O cuidado geriátrico edifica-se na relação que se desenvolve, atribuída de sentido, e assenta-se num encontro/interação entre os atores sob influência do contexto em que está inserido. Os diferentes modos e formas de confortar objetivam facilitar/aumentar o conforto, aliviar o desconforto e/ou investir no conforto potencial.

An inventory of the theses on hepatitis of the Faculdade de Medicina of the Universidade Federal do Rio de Janeiro between 1837 and 2000 is presented. The analysis indicates the potential and limits for discussion of the evolutionary framework of scientific knowledge on these health problems in Brazil. The theories are also discussed in light of their scientific reference points and the technological and social changes that influenced them. The landmarks in medical education and knowledge about hepatitis are identified and categorized, considering that the theses reveal at the very least the state of the art on the subject. The study makes it possible to explore the foundations upon which the scientific knowledge on hepatitis were built and indicate possibilities for research in the reconstruction of scientific knowledge of other health problems.

Spacecraft Doppler tracking with a VLBI antenna

Preliminary results are reported from Doppler-shift measurements to the Voyager-2 spacecraft at a distance of 26 AU, obtained using the 32-m VLBI antenna at Medicina (Italy) during July and August 1988. The apparatus comprises the el-az antenna, an S-X-band receiver, a hydrogen maser to generate the reference signal, a Mark III VLBI terminal, and a digital tone extractor capable of isolating a tone of known frequency from a noisy signal and giving its phase and amplitude. A signal transmitted in S-band from the NASA Deep Space Network (DSN) station in Australia and retransmitted coherently in X-band by Voyager, was received 7 h 6 min later at Medicina and at the DSN station in Madrid. Sample data are presented graphically and shown to be of generally high quality; further in-depth analysis is under way.

The 2001 edition of the Journal Citation Reports (JCR) includes only 13 Spanish medical journals. The impact factor (IF) of the rest of Spanish medical journals is unknown. The aim of this study is to determine the IF of the main Spanish medical journals, taking also into account the references from journals not covered by the SCI. A set of 87 Spanish medical journals was selected from the national database IME and other international databases. All citable articles published in these journals in 2001 were analyzed, extracting their bibliographic references to articles published in 1999, 2000 and 2001. The indicators obtained for each journal were the number of cites, the IF and the immediacy index. Among the 87 source journals, 74 were not included in the JCR. From them, 5,388 bibliographic references were examined, identifying the journals cited. Final indicators were obtained adding these results to the ones obtained by using the Science Citation Index. The most cited journal was Medicina Clinica (768 cites), and the highest IF were attained by Histology and Histopathology (IF = 1.866), International Journal of Developmental Biology (IF = 1.654) and Medicina Clinica (IF = 1.125). This work has permitted to obtain the IF of 87 Spanish medical journals. Already detected in previous works, the leadership of the journal Medicina Clinica in Spanish medicine is confirmed. Spanish medical journals published in English have received a small number of cites from the ones published in Spanish. A low impact factor is not necessarily related to lack of quality, merit or relevance.

Gravity and Height Variations at Medicina, Italy

Bruni, Sara; Zerbini, Susanna; Errico, Maddalena; Santi, Efisio; Wziontek, Hartmut

2017-04-01

Since 1996, at the Medicina station, height and gravity variations are monitored continuously by means of GPS, VLBI and superconducting gravimeter (SG) data. Additionally, absolute gravity observations are performed twice a year and environmental parameters, among others water table levels, are regularly acquired. Levelling between the different monuments at the site area is also carried out repeatedly to constrain local ties in the vertical position. Two GPS systems are located very close to each other, and both are in close proximity to the VLBI antenna. Twenty years of data are now available, which allow investigating both long- and short-period height and gravity signals together with their relevant correlations. Natural land subsidence, which is well known to occur in the area, is a major component of the observed long-term behavior; however, non-linear long-period signatures are also present in the time series. On a shorter time scale, fingerprints of the water table seasonal oscillations can be recognized in the data. The Medicina site is characterized by clayey soil subjected to consolidation effects when the water table lowers during summer periods. The pillar on which the SG is installed is especially affected because of its shallow foundation, causing height decreases in the order of 2.5-3 cm for water table lowering of 2 m. This study presents a comparative analysis of the different data sets with the aim of separating mass and deformation contributions in the SG gravity record.

Terapia fibrinolítica sistêmica no tromboembolismo pulmonar

Resumo O tromboembolismo pulmonar permanece como um grande desafio terapêutico para os médicos especialistas, pois, apesar de todo investimento e desenvolvimento em seu diagnóstico, profilaxia e tratamento, essa condição continua sendo a principal causa de morte evitável em ambiente hospitalar. Ainda restam muitas dúvidas em relação a qual perfil de paciente vai se beneficiar de fato da terapia fibrinolítica sistêmica, sem ficar exposto a um grande risco de sangramento. A estratificação de risco e a avaliação do prognóstico do evento, através de escores clínicos de insuficiência ventricular direita, marcadores de dilatação e disfunção do ventrículo direito e avaliação da massa trombótica, associados ou de forma isolada, são ferramentas que podem auxiliar na identificação do paciente que irá se beneficiar dessa terapia. Os únicos consensos em relação à terapia fibrinolítica no tratamento do tromboembolismo pulmonar são: não deve ser indicada de forma rotineira; nenhum dos escores ou marcadores, isoladamente, devem justificar seu uso; e os pacientes com instabilidade hemodinâmica são os mais beneficiados. Além disto, deve-se avaliar cada caso em relação ao risco de sangramento, especialmente no sistema nervoso central. PMID:29930636

To analyze the use of nursing terminology as an instrument of the nursing work process in Collective Health. Exploratory case study. For data collection was conducted a group interview with 24 nurses working in health units of a municipality in south central Paraná, Brazil. Data were analyzed in the light of interdependence between the structural, particular and singular dimensions contained in the Theory of Nursing Praxis Intervention in Collective Health. The situations interfering with improper use were the lack of knowledge about the origin and purpose of terminology, lack of training, and non-mandatory use. Although the nursing terminology is used as an instrument in the nursing work process in collective health, it requires training to be recognized as a classification system. At the same time, institutional policies should be employed to ensure the effective use of these instruments. Analisar a utilização de terminologia de enfermagem como instrumento do processo de trabalho do enfermeiro em Saúde Coletiva. Estudo de caso exploratório. Para coleta de dados foi realizada entrevista em grupo com 24 enfermeiros que atuam nas unidades de saúde de um município no centro-sul do Paraná, Brasil. Os dados foram analisados à luz da interdependência entre as dimensões estrutural, particular e singular contidas na Teoria da Intervenção Práxica de Enfermagem em Saúde Coletiva. As situações que interferiram na utilização inadequada foram o desconhecimento sobre origem e finalidade da terminologia, a falta de treinamento e a não obrigatoriedade de uso. A terminologia de enfermagem, apesar de utilizada como instrumento no processo de trabalho de enfermeiros em Saúde Coletiva, necessita de capacitação para ser reconhecida como sistema classificatório. Ao mesmo tempo, políticas institucionais devem ser empregadas no intuito de garantir a efetiva utilização destes instrumentos.

Mentors also need support: a study on their difficulties and resources in medical schools.

Mentors have been recognized as important elements in the personal and professional development of medical students. However, few investigations have sought to understand their development, needs and difficulties. Our objective was to investigate the perceptions of a group of mentors regarding difficulties experienced over time and the resources used to face up to them. Qualitative exploratory study on mentors at Faculdade de Medicina da Universidade de São Paulo (FMUSP). In the FMUSP Mentoring Program, mentors follow and guide students throughout the course, and are responsible for heterogeneous group of students, in relation to the academic year. Semi-structured interviews were conducted with 14 FMUSP mentors. For many of the mentors, the difficulties related to initial doubts about the role, frustration with the students' attendance and overloading of daily tasks. To address such difficulties, these mentors used external resources and their own life experience and personal way of dealing with situations. Some mentors did not perceive difficulties for themselves or for students. Like in other mentoring programs, many difficulties perceived by mentors seem to be derived from the context of medical education itself. However, unlike in other experiences, FMUSP mentors do not feel that there is lack of support for their role, since this is regularly provided in the structure and dynamics of the program. The "difficulty in perceiving difficulties", presented by some mentors, demands further investigation for better and greater understanding.

Biomedical journals are the most used and important venue to disseminate and interchange scientific information, and evaluation is an important component. A bibliometric study was conducted on the productivity, visibility and citation analysis of the Revista Peruana de Medicina Experimental y Salud Pública (RPMESP), from 2002 to 2009. During this period, the RPMESP published about 62 documents per year, 55.3% were research articles. The visibility of RPMESP, determined among three databases (SISBIB-UNMSM, SciELO-Peru, and REDALYC), was irregular, increasing on July 2006, with the highest access on October 2009 (117,618 hits). 43.0% of publications were cited. The calculated impact factor in ISI journals was 0.04 in 2009. In conclusion, the citation of RPMESP shows a slowly growing during the period 2002-2009. It is hoped that the RPMESP increase its visibility and impact after its inclusion in MEDLINE.

Earth orientation determinations by short duration VLBI observations

1994-03-01

In May 1989 and April 1990 the radio telescopes of the Wettzell Geodetic Fundamental Station in Germany and of the Shanghai Observatory near Seshan in China observed two series of daily VLBI experiments of short duration for precise determination of UT1. In 1990 a few experiments were complemented by the Hartebeesthoek Radio Astronomy Observatory in South Africa and the Medicina telescope of the Bologna Istituto di Radioastronomia in Italy. Employing the South African station together with the east-west baseline formed by the observatories of Seshan and Medicina permitted simultaneous determinations of UT1 and polar motion. Here we report on the results of these observations. Comparing the UT1 results with those of the IRIS Intensive series gives a clear indication of the absolute accuracy of such short duration VLBI measurements which is estimated to be of the order of ±60 µs.

We analyze the construction of the notion of the 'lowlife' in the city of Buenos Aires in the Revista de Criminología, Psiquiatría y Medicina Legal, from 1914-1923. We shall analyze the notion of 'lowlife', meaning behaviors situated in a border zone between crime and madness, from the point of view of prevention and perception of danger. The first way of analyzing the 'lowlife' examines institutional projects that were related to eugenics and that advocated preventive detention of dangerous people, 'alcoholists' and vagrants. The second involves identifying in moral and physical terms the kind of people who were targeted in the creation of intervention projects for those considered to be 'lowlifes', who could potentially damage the fabric of society in some way.

Height biases and scale variations in VLBI networks due to antenna gravitational deformations

NASA Astrophysics Data System (ADS)

Abbondanza, Claudio; Sarti, Pierguido; Petrov, Leonid; Negusini, Monia

2010-05-01

The impact of signal path variations (SPVs) caused by antenna gravity deformations on geodetic VLBI results is evaluated for the first time. Elevation-dependent models of SPV for Medicina and Noto (Italy) telescopes were derived from a combination of terrestrial surveying methods to account for gravitational deformations. After applying these models, estimates of the antenna reference point (ARP) positions are shifted upward by 8.9 mm and 6.7 mm, respectively. The impact on other parameters is negligible. To infer the impact of antenna gravity deformations on the entire VLBI network, lacking measurements for other telescopes, we rescaled the SPV models of Medicina and Noto for other antennas according to their size. The effects are changes in VLBI heights in the range [-3,73] mm and a significant net scale increase of 0.3 - 0.8 ppb. This demonstrates the need to include SPV models in routine VLBI data analysis.

Coccidioidomycosis is an emerging fungal disease in Brazil; adequate maintenance and authentication of Coccidioides isolates are essential for research into genetic diversity of the environmental organisms, as well as for understanding the human disease. Seventeen Coccidioides isolates maintained under mineral oil since 1975 in the Instituto de Medicina Tropical de São Paulo (IMTSP) culture collection, Brazil, were evaluated with respect to their viability, morphological characteristics and genetic features in order to authenticate these fungal cultures. Only five isolates were viable after almost 30 years, showing typical morphological characteristics, and sequencing analysis using Coi-F and Coi-R primers revealed 99% identity with Coccidioides genera. These five isolates were then preserved in liquid nitrogen and sterile water, and remained viable after two years of storage under these conditions, maintaining the same features.

To evaluate the profile of anophthalmic cavity carriers and patients' evolution with the employed treatments. Retrospective study carried out at Faculdade de Medicina de Botucatu, to evaluate the profile and the evolution of patients with anophthalmic cavity treated in our service. Data were evaluated according to the frequency of occurrence and analysis of association. Anophthalmic cavity was more frequently observed in young males, workers in activities carried on with their hands. Trauma and phthisis bulbi were the most frequent causes, with differences according to age and gender. The complications were high (57.1% of cases), the majority occurred belatedly. Trauma is still an important cause of loss of the eye. The complications during the follow-up of the patient are frequent, occurring in general, very late, which reinforces the need for periodic and prolonged monitoring of patients with anophthalmic cavity.

Song, Hyun Seok

2011-01-01

Background This study compared the results of patients treated for ulnar impaction syndrome using an ulnar shortening osteotomy (USO) alone with those treated with combined arthroscopic debridement and USO. Methods The results of 27 wrists were reviewed retrospectively. They were divided into three groups: group A (USO alone, 10 cases), group B (combined arthroscopic debridement and USO, 9 cases), and group C (arthroscopic triangular fibrocartilage complex [TFCC] debridement alone, 8 cases). The wrist function was evaluated using the modified Mayo wrist score, disabilities of the arm, shoulder and hand (DASH) score and Chun and Palmer grading system. Results The modified Mayo wrist score in groups A, B, and C was 74.5 ± 8.9, 73.9 ± 11.6, and 61.3 ± 10.2, respectively (p < 0.05). The DASH score in groups A, B, and C was 15.6 ± 11.8, 19.3 ± 11.9, and 33.2 ± 8.5, respectively (p < 0.05). The average Chun and Palmer grading score in groups A and B was 85.7 ± 8.9 and 84.7 ± 6.7, respectively. The difference in the Mayo wrist score, DASH score and Chun and Palmer grading score between group A and B was not significant (p > 0.05). Conclusions Both USO alone and combined arthroscopic TFCC debridement with USO improved the wrist function and reduced the level of pain in the patients treated for ulnar impaction syndrome. USO alone may be the preferred method of treatment in patients if the torn flap of TFCC is not unstable. PMID:21909465

There aren't any objective methods that may help in standard evaluation of oral surgery patient's psycho-emotional status. Without any standardized evaluation, two main problems appear: heterogeneity between studies and ineffective patient's evaluation. Therefore, Universal Scale in Oral Surgery (USOS) for patient's psycho-emotional status rating has previously been proposed by authors. The aim of present study is to assess the clinical effectivity and validate the Universal Scale in Oral Surgery in case of outpatient tooth extraction for adult healthy patients. Clinical trial to validate the USOS for patient's psycho-emotional status rating was performed. In total 90 patients, that came for outpatient dental extraction to Lithuanian University of Health Sciences Oral and Maxillofacial Surgery Department ambulatory, were enrolled in clinical trial. Patients filled self-reported questionnaires before the procedure. Operating surgeon rated USOS for patient's psycho-emotional status rating doctor's part questionnaire after the procedure. 4 - 6 weeks later all patients were asked to fill USOS for patient's psycho-emotional status rating questionnaire retrospectively. According to the statistical analysis, the final composition of USOS for patient's psycho-emotional status rating that would fit to reliability coefficient should be composed from 6 patient part questions and 3 general doctor part questions. Universal Scale in Oral Surgery for patient's psycho-emotional status rating is a novel, doctor and patient rated scale which is suitable for clinical and scientific usage.

The aim of this study was to compare the oncologic and reproductive outcomes of patients with borderline ovarian tumours (BOTs) who were treated with cystectomy or unilateral salpingo-oophorectomy (USO). The medical records of patients with BOTs who were treated between 1997 and 2009 were reviewed retrospectively. The recurrence rates were compared between the USO and cystectomy groups. The reproductive outcomes were assessed by telephone interviews. Patients with BOTs underwent a USO (n= 117) or cystectomy (n= 38). There were 12 patients who had recurrences: 1 patient had an invasive recurrence and 11 had borderline recurrences. The recurrence rate in the USO group (6.0%) was lower than in the cystectomy group (13.2%); however, this difference was not statistically significant (P= 0.110). All of the patients with recurrences were successfully treated with surgery and there was no clinical evidence of disease. Of the 116 patients contacted by telephone, 113 (97.4%) resumed menstruation following the surgery, and 45 of the 52 patients (86.5%) who attempted to conceive had successful pregnancies. USO (89.2%), like cystectomy (85.7%), resulted in excellent pregnancy rates for patients with BOTs. A USO is an appropriate treatment for women with BOTs who wish to preserve fertility. However, a cystectomy is a satisfactory fertility-sparing therapy when a cystectomy is the only surgical option.

To determine the prevalence of and the factors associated with latent Mycobacterium tuberculosis infection (LTBI) in prisoners in the state of Minas Gerais, Brazil. This was a cross-sectional cohort study conducted in two prisons in Minas Gerais. Tuberculin skin tests were performed in the individuals who agreed to participate in the study. A total of 1,120 individuals were selected for inclusion in this study. The prevalence of LTBI was 25.2%. In the multivariate analysis, LTBI was associated with self-reported contact with active tuberculosis patients within prisons (adjusted OR = 1.51; 95% CI: 1.05-2.18) and use of inhaled drugs (adjusted OR = 1.48; 95% CI: 1.03-2.13). Respiratory symptoms were identified in 131 (11.7%) of the participants. Serological testing for HIV was performed in 940 (83.9%) of the participants, and the result was positive in 5 (0.5%). Two cases of active tuberculosis were identified during the study period. Within the prisons under study, the prevalence of LTBI was high. In addition, LTBI was associated with self-reported contact with active tuberculosis patients and with the use of inhaled drugs. Our findings demonstrate that it is necessary to improve the conditions in prisons, as well as to introduce strategies, such as chest X-ray screening, in order to detect tuberculosis cases and, consequently, reduce M. tuberculosis infection within the prison system.

Foram selecionados 1.120 indivíduos para a pesquisa. A prevalência da ILTB foi de 25,2%. Na análise multivariada, a ILTB esteve associada com relato de contato com caso de tuberculose ativa dentro da penitenciária (OR ajustada = 1,51; IC95%: 1,05-2,18) e uso de drogas inaláveis (OR ajustada = 1,48; IC95%: 1,03-2,13). Foram identificados 131 pacientes sintomáticos respiratórios (11,7%). O teste anti-HIV foi realizado em 940 (83,9%) dos participantes, sendo positivo em 5 indivíduos (0,5%). Dois casos de tuberculose ativa foram identificados no período do estudo. A prevalência de ILTB dentro das penitenciárias estudadas foi alta. Além disso, a ILTB estava associada ao relato de contato com casos de tuberculose e ao uso de drogas inaláveis. Nossos achados demonstram que é necessária a melhoria das condições de encarceramento e a utilização de outras estratégias, como a triagem por radiografia de tórax, para a descoberta de casos de tuberculose e redução da infecção pelo M. tuberculosis no sistema penitenciário.

to analyze demographic Brazilian medical data from the national public healthcare system (SUS), which provides free universal health coverage for the entire population, and discuss the problems revealed, with particular focus on surgical care. data was obtained from public healthcare databases including the Medical Demography, the Brazilian Federal Council of Medicine, the Brazilian Institute of Geography and Statistics, and the National Database of Healthcare Establishments. Density and distribution of the medical workforce and healthcare facilities were calculated, and the geographic regions were analyzed using the public private inequality index. Brazil has an average of two physicians for every 1,000 inhabitants, who are unequally distributed throughout the country. There are 22,276 board certified general surgeons in Brazil (11.49 for every 100,000 people). The country currently has 257 medical schools, with 25,159 vacancies for medical students each year, with only around 13,500 vacancies for residency. The public private inequality index is 3.90 for the country, and ranges from 1.63 in the Rio de Janeiro up to 12.06 in Bahia. A significant part of the local population still faces many difficulties in accessing surgical care, particularly in the north and northeast of the country, where there are fewer hospitals and surgeons. Physicians and surgeons are particularly scarce in the public health system nationwide, and better incentives are needed to ensure an equal public and private workforce. analisar dados demográficos do Sistema Único de Saúde (SUS) brasileiro, que promove cobertura de saúde universal a toda população, e discutir os problemas revelados, com particular ênfase nos cuidados cirúrgicos. os dados foram obtidos a partir dos bancos de dados de saúde pública da Demografia Médica, do Conselho Federal de Medicina, do Instituto Brasileiro de Geografia e Estatística e do Cadastro Nacional dos Estabelecimentos de Saúde. A densidade e a distribuição do trabalho médico e dos estabelecimentos de saúde foram avaliadas, e as regiões geográficas foram analisadas usando o índice de desigualdade público-privado (IDPP). o Brasil tem, em média, dois médicos por 1000 habitantes, que são desigualmente distribuídos no país. Tem 22.276 cirurgiões gerais certificados (11,49 por 100.000 habitantes). Existem no país 257 escolas de medicina, com 25.159 vagas por ano, e apenas cerca de 13.500 vagas de residência médica. O índice de desigualdade público-privado é de 3,90 para o país e varia de 1,63 no Rio de Janeiro até 12,06 na Bahia. uma parte significativa da população brasileira ainda encontra muitas dificuldades no acesso ao tratamento cirúrgico, particularmente na região norte e nordeste do país. Médicos e, particularmente, cirurgiões são escassos no sistema público de saúde e incentivos devem ser criados para assegurar uma força médica igual no setor público e no setor privado em todas as regiões do país.

The objective of this study is to analyze the association between intimate partner violence against women and maternal educational practice directed to children at the beginning of formal education. This is a cross-sectional study, carried out between 2013 and 2014, with 631 mother/child pairs, registered in the Family Health Strategy of the Health District II of the city of Recife, State of Pernambuco, Brazil. It integrates a prospective cohort study designed to investigate the consequences of exposure to intimate partner violence in relation to the child who was born between 2005 and 2006. The maternal educational practice has been assessed by the Parent-Child Conflict Tactics Scale and the intimate partner violence by a questionnaire adapted from the Multi-Country Study on Women's Health and Domestic Violence of the World Health Organization. Intimate partner violence referred to the last 12 months and was defined by specific acts of psychological, physical, and sexual violence inflicted to women by the partner. The crude and adjusted prevalence ratios were estimated for the association studied, using log-binomial regression. The prevalence of intimate partner violence was 24.4%, and violent maternal educational practice was 93.8%. The use of non-violent discipline was mentioned by 97.6% of the women, coexisting with violent strategies of discipline. Children whose mothers reported intimate partner violence presented a higher chance of suffering psychological aggression (PR = 2.2; 95%CI 1.0-4.7). The violence suffered by the mother interferes in the parental education. The findings show high prevalence of violent maternal educational practice, pointing to the need for interventions that minimize the damage of violence in women and children. Analisar a associação entre a violência pelo parceiro íntimo contra a mulher e a prática educativa materna direcionada às crianças no início da escolaridade formal. Estudo transversal, realizado entre 2013 e 2014, com 631 pares mãe/criança, cadastradas na Estratégia de Saúde da Família do Distrito Sanitário II da cidade do Recife, Pernambuco. Integra o estudo de coorte prospectivo delineado para investigar as consequências da exposição à violência pelo parceiro íntimo para a criança que nasceu da gestação que ocorreu entre 2005 e 2006. A prática educativa materna foi avaliada pela escala de conflitos Parent-Child Conflict Tactics Scale e a violência pelo parceiro íntimo por um questionário adaptado do Estudo Multipaíses sobre a Saúde da Mulher e Violência Doméstica da Organização Mundial da Saúde. A violência pelo parceiro íntimo referiu-se aos últimos 12 meses e foi definida por atos concretos de violência psicológica, física e sexual infligidos à mulher pelo parceiro. Foram estimadas as razões de prevalência brutas e ajustadas para a associação estudada, utilizando-se a regressão log-binominal. A prevalência da violência pelo parceiro íntimo foi de 24,4%, e da prática educativa materna violenta de 93,8%. O uso de disciplina não violenta foi referido por 97,6% das mulheres, coexistindo com estratégias violentas de disciplinamento. As crianças cujas mães relataram violência pelo parceiro íntimo apresentaram maior chance de sofrer agressão psicológica (RP = 2,2; IC95% 1,0-4,7). A violência sofrida pela mãe interfere na educação parental. Os achados demonstram alta prevalência de prática educativa materna que perpassa pela violência, o que aponta para a necessidade de intervenções que minimizem os prejuízos da violência na mulher e na criança.

A bone tissue engineering strategy based on starch scaffolds and bone marrow cells cultured in a flow perfusion bioreactor

Gomes, Maria Manuela Estima

A Engenharia de Tecidos e uma area cientifica em continua expansao. Os desenvolvimentos conseguidos por esta area tem contribuido significativamente para diversos avancos no campo da Medicina Regenerativa. Esta ciencia interdisciplinar combina os conhecimentos de diversas outras areas, tao distintas como a Engenharia de Materiais e a Biologia, com o objectivo de desenvolver substitutos sinteticos para tecidos humanos. Para se atingir este objectivo utilizam-se, de uma forma generica, combinacoes especificas de celulas e de um material de suporte tridimensional com propriedades adequadas, gerando um material hibrido cujas caracteristicas podem ainda ser moduladas atraves do sistema de cultura usado. A presente tese e centrada no desenvolvimento de estrategias de engenharia de tecido osseo baseadas na cultura in vitro de celulas previamente "semeadas" num suporte tridimensional ("scaffold"). Esta estrategia permite que as celulas adiram ao suporte, proliferem e segreguem matriz extracelular especifica do tecido osseo, ate se obter um substituto artificial funcional com caracteristicas do tecido original, que pode finalmente ser transplantado para tratar o defeito em causa. Para que uma estrategia deste tipo seja bem sucedida, pelo menos tres componentes fundamentais devem ser cuidadosamente estudados: o material de suporte (scaffold), as celulas a usar e o sistema de cultura in vitro. Dai que os principais objectivos desta tese estejam relacionados com estes tres aspectos, nomeadamente: • Desenvolvimento de scaffolds biodegradaveis a partir de polimeros a base de amido de milho que induzam a adesao e proliferacao celular e que apresentem propriedades adequadas, tais como a porosidade e interconectividade entre poros, de forma a proporcionar um ambiente que favoreca o desenvolvimento in vitro de um material hibrido com caracteristicas similares ao osso humano. • Estudo da utilizacao de celulas da medula ossea como uma potencial fonte de celulas para engenharia do tecido osseo, uma vez que estas celulas podem ser facilmente recolhidas do proprio paciente a tratar por metodos nao-invasivos (bioppsia) e em quantidades suficientes. Alem disso, tratando-se de uma fonte de celulas autologas (obtidas do proprio paciente) permitem evitar os riscos de transmissao de doencas contagiosas e/ou de rejeicao pelo sistema imunologico. • Estudo da influencia das condicoes de cultura in vitro geradas por um bioreactor de perfusao (em comparacao com os metodos tradicionais de cultura em condicoes estaticas) no desenvolvimento dos materiais hibridos, compostos pelas celulas e scaffolds, assim como as interaccoes do ambiente proporcionado por este sistema de cultura com as diferentes estruturas/arquitecturas e porosidades dos scaffolds utilizados. Estes objectivos convergem para o objectivo geral desta tese que consistiu no desenvolvimento de uma terapia de engenharia do tecido osseo alternativa as existentes e com potencial para vir a ser posteriormente utilizada na pratica clinica. Este objectivo foi avaliado atraves do estudo da funcionalidade dos materiais hibridos obtidos em diferentes condicoes de cultura in vitro (e utilizando diferentes scaffolds), partindo do principio que o sistema de perfusao poderia eventualmente superar as limitacoes de difusao tipicas dos sistema de cultura estatica e simultaneamente proporcionar estimulos mecânicos as celulas, semelhantes aos encontrados em condicoes fisiologicas.

To investigate the inter-relation between high sensitivity C-reactive protein and glycated hemoglobin in prediction of risk of obstructive sleep apnea. We included all individuals participating in a check-up program at the Preventive Medicine Center of Hospital Israelita Albert Einstein in 2014. The Berlin questionnaire for risk of obstructive sleep apnea was used, and the high sensitivity C-reactive protein and glycated hemoglobin levels were evaluated. The sample included 7,115 participants (age 43.4±9.6 years, 24.4% women). The Berlin questionnaire showed changes in 434 (6.1%) individuals. This finding was associated with high sensitivity C-reactive protein and glycated hemoglobin levels (p<0.001). However, only the association between the Berlin questionnaire result and glycated hemoglobin remained significant in the adjusted multivariate analysis, for the traditional risk factors and for an additional model, including high-density lipoprotein cholesterol and triglycerides. The glycated hemoglobin, even below the threshold for diagnosis of diabetes, is independently associated with obstructive sleep apnea syndrome, even after adjustment for obesity and C-reactive protein. These findings suggest a possible pathophysiological link between changes in insulin resistance and obstructive sleep apnea syndrome, independently from obesity or low-grade inflammation. Investigar a inter-relação entre proteína C-reativa de alta sensibilidade e hemoglobina glicada na predição do risco de apneia obstrutiva do sono. Foram incluídos todos os indivíduos participantes do programa de check-up do Centro de Medicina Preventiva Hospital Israelita Albert Einstein em 2014. Foi aplicado o questionário de Berlin sobre risco de apneia do sono, e avaliadas as dosagens de hemoglobina glicada e proteína C-reativa de alta sensibilidade. Foram incluídos 7.115 participantes (idade 43,4±9,6 anos, 24,4% mulheres). A prevalência de alteração no questionário de Berlin foi de 434 (6,1%). A alteração do questionário de Berlin associou-se positivamente aos resultados da proteína C-reativa de alta sensibilidade e da hemoglobina glicada (p<0,001). No entanto, apenas a associação entre o resultado do questionário de Berlin e a hemoglobina glicada permaneceu significativa na análise multivariada ajustada tanto para fatores de risco tradicionais quanto para um modelo adicional, que incluiu também lipoproteína de alta densidade-colesterol (HDL-c) e triglicérides. A hemoglobina glicada, mesmo em valores abaixo do critério diagnóstico para diabetes mellitus, está associada de forma independente ao risco para síndrome da apneia obstrutiva do sono, mesmo após ajuste para obesidade e proteína C-reativa. Estes achados sugerem possível ligação fisiopatológica entre alterações na resistência insulínica e a síndrome da apneia obstrutiva do sono, que independe da obesidade ou inflamação de baixo grau.

Study on the effects of sonolysis, ozonolysis and US/O3 system on the decomposition of p-chlorophenol in aqueous solutions indicated that in the cases of US/O3 system, individual ozonolysis and sonolysis, the decomposition rate of p-chlorophenol reached 78.78%, 56.20%, 2.79% after a 16-min reaction while its CODcr (chemical oxygen demand) removal rate was 97.02%, 62.17%, 3.67% after a 120-min reaction. The decomposition reaction of p-chlorophenol follows pseudo-first-order kinetics. The enhancement factors of p-chlorophenol and its CODcr under US/O3 system reached 63% and 237% respectively. The main intermediates during the decomposition include catechol, hydroquinone, p-benzoquinone, phenol, fumaric acid, maleic acid, oxalic acid and formic acid. The decomposition mechanism of p-chlorophenol was also discussed. PMID:15909343

Substance use and a history of childhood sexual abuse (CSA) are risk factors for unprotected sex among women, yet questions remain as to how their combined influence may differentially affect sexual risk. The current study investigated how complex relationships among drug use and CSA may contribute to unprotected sexual occasions (USO). A Generalized Linear Mixed Model was used to examine the interaction between current cocaine/stimulants and opioid use and CSA on number of USOs in a sample of 214 sexually active women in outpatient methadone maintenance treatment. For women with CSA, an increase in days of cocaine/stimulant use was associated with a significant increase in USOs. In contrast, an increase in days of opiate use was associated with a significant decrease in USOs. For the group of women who did not report CSA, there was a significant increase in USOs with increased opiate use. Findings indicate that CSA is related to unprotected sexual occasions depending on drug type and severity of use. Women with CSA using cocaine are at particularly high risk for having unprotected sex and should be specifically targeted for HIV prevention interventions.

To analyze if the self-perception of oral health in the urban context is associated with sociodemographic factors that interfere in the life quality of oral health. Cross-sectional study with convenience sample of older individuals (65 years old or more) enrolled in the Agrupamento de Centros de Saúde de Lisboa Norte (ACES Lisboa Norte - Health Centers Groupings North Lisbon). The self-perception of oral health and associated life quality was evaluated by the Geriatric Oral Health Assessment Index and the individuals were classified according to sociodemographic characteristics. The internal consistency of the questionnaire was evaluated by Cronbach's alpha (α). Later, we used binary logistic regression models to characterize the factors associated with the self-perception of oral health, considering the sociodemographic variables and the older adults' clinical conditions of oral health and establishing the crude and adjusted (to age) odds ratios and their 90% confidence intervals. A total of 369 older adults participated in this study, with an average age of 74.2 years (SD = 6.75); 62.9% were female. On average, the index was moderated, with tendency to be high: 32.9 (SD = 3.6; 12-36 interval). The Cronbach's alpha was high: 0.805. Age, marital status, and the last dental appointment were the factors significantly associated with self-perception of oral health. The study shows that these individuals have a moderate, with tendency to high, self-perception of oral health. The self-perception of oral health assessment allowed us to identify the main associated sociodemographic factors. This instrument can help guiding planning strategies and oral health promotion directed toward a better life quality for this population group.

Posteriormente, foram utilizados modelos de regressão logística binária para caracterizar os factores associados com a autopercepção de saúde bucal considerando as variáveis sociodemográficas e de condições clínicas de saúde bucal dos idosos e determinados os odds ratios bruto e ajustado (à idade) e respectivos intervalos de confiança a 90%. Participaram 369 idosos, com média de idade de 74,2 anos (DP = 6,75); 62,9% eram do sexo feminino. Em média, o índice foi moderado com tendência a elevado: 32,9 (DP = 3,6; intervalo 12-36). O alfa de Cronbach foi elevado: 0,805. A idade, o estado civil e a última consulta de Medicina Dentária foram os factores significativamente associados a autopercepção da saúde bucal. O estudo mostra que esses indivíduos apresentam uma autopercepção de saúde bucal moderada, com tendência a elevada. A avaliação da autopercepção da saúde bucal permitiu identificar os principais factores sociodemográficos associados. Este instrumento pode contribuir para orientar as estratégias de planejamento e promoção da saúde bucal direcionadas para uma melhor qualidade de vida deste grupo populacional.

The objective of this study was to analyze the association between the socioeconomic characteristics and the access to or use of health services among older adults. This is a systematic review of the literature. The search has been carried out in the databases PubMed, LILACS and Web of Science, without restriction of dates and languages; however we have included only articles published in Portuguese, English, and Spanish. The inclusion criteria were: observational design, socioeconomic factors as variables of interest in the analysis of the access to or use of health services among older adults, representative sample of the target population, adjustment for confounding factors, and no selection bias. We have found 5,096 articles after deleting duplicates and 36 of them have been selected for review after the process of reading and evaluating the inclusion criteria. Higher income and education have been associated with the use and access to medical appointments in developing countries and some developed countries. The same association has been observed in dental appointments in all countries. Most studies have shown no association between socioeconomic characteristics and the use of inpatient and emergency services. We have identified greater use of home visits in lower-income individuals, with the exception of the United States. We have observed an unequal access to or use of health services in most countries, varying according to the type of service used. The expansion of the health care coverage is necessary to reduce this unequal access generated by social inequities. Analisar a associação entre características socioeconômicas e acesso ou utilização de serviços de saúde entre idosos. Revisão sistemática da literatura. A busca foi realizada nas bases de dados PubMed, Lilacs e Web of Science, sem restrição de datas e idiomas, entretanto foram incluídos somente os artigos publicados em português, inglês e espanhol. Foram critérios de inclusão: ter delineamento observacional; possuir os fatores socioeconômicos como variáveis de interesse na análise do acesso ou utilização de serviços de saúde entre idosos; ter amostra representativa da população alvo; fazer ajuste para fatores de confusão; e não apresentar viés de seleção. Foram encontrados 5.096 artigos após a exclusão de duplicidades e 36 foram selecionados para a revisão após o processo de leitura e avaliação dos critérios de inclusão. Maior renda e escolaridade estiveram associadas à utilização e acesso a consultas médicas nos países em desenvolvimento e em alguns países desenvolvidos. A mesma associação foi observada nas consultas odontológicas em todos os países. A maioria dos estudos não apresentou associação entre características socioeconômicas e uso de serviços de internação e emergência. Foi identificado maior uso de visita domiciliar em indivíduos de menor renda, com exceção dos Estados Unidos. Observou-se desigualdade no acesso ou na utilização de serviços de saúde na maior parte dos países, variando em relação ao tipo de serviço utilizado. A ampliação da cobertura de serviços de saúde faz-se necessária para a redução da desigualdade no acesso gerada por iniquidades sociais.

The convenience sample was composed by a hundred and twenty one senior caregivers (Avg=70.5 ± 7.2 years, 73% women). They answered a questionnaire to check the physical and cognitive demands of care, the Zarit Burden Interview (ZBI), the California Inventory of Coping Strategies and the Geriatric Depression Scale (GDS-15). ZBI showed good internal consistency and also for the three factors emerging from factor analysis, explaining 44% of variability. ZBI is positively related with objective care demands (p < 0.001), depression (p = 0.006) and use of dysfunctional coping strategies (p = 0.0007). ZBI is of interest to be applied to aged caregivers and the association of higher degrees of burden, dysfunctional coping and depression show a vulnerability scenario that may affect to older people taking care of other elderly. derivar indicadores psicométricos de validade de construto e consistência interna da escala de sobrecarga de cuidadores de Zarit Burden Interview e descrever associações desta com medidas referentes às demandas de cuidado, estratégias de enfrentamento e depressão em cuidadores idosos. estudo descritivo, transversal e correlacional.

Our main objective was to analyse how the evolution of household assets ownership affected the Indicador Econômico Nacional (IEN - National Wealth index) and to point out the most stable assets and which lost importance more quickly. We analysed the trend of the ownership of each IEN variable and the distribution of the households' scores. We calculated the correlation coefficients of each variable separately with the IEN score and the household income. We also evaluated how the changes of the score distribution over time affected the validity of the published reference cut-points. We used data from consortium surveys conducted every two years from 2002 to 2014 in the city of Pelotas, Brazil. An increase in the educational level of household heads and in the ownership of all IEN assets, except radio and telephone, was observed in the study period. In general, the correlation of the assets with the IEN scores decreased over time. There was an increase in the score, with a consequent increase in the quintiles cut-points, but the distance between these cut-points had no significant variation. Thus, the reference cut-points for Pelotas, quickly became outdated. Some assets showed greatly reduction on its importance for the indicator, and the reference cut-points became obsolete very quickly. It is essential for a standardized wealth (or asset) index with research purposes to be updated frequently, especially the cut-points of reference distribution. Analisar como a evolução temporal da posse de bens domésticos afetou o Indicador Econômico Nacional e como essas mudanças afetaram o poder discriminatório do indicador. Analisou-se a evolução temporal da posse de cada uma das variáveis do Indicador Econômico Nacional, bem como da distribuição do escore dos domicílios. Utilizamos dados de inquéritos populacionais realizados bienalmente no município de Pelotas, RS, de 2002 a 2014. Foi calculado o coeficiente de correlação de cada variável isoladamente com o escore do Indicador Econômico Nacional e com a renda familiar. Avaliamos também como a variação da distribuição do escore ao longo do tempo afetou a validade da utilização dos pontos de corte de referência publicados. Houve aumento da escolaridade dos chefes das famílias e da posse de todos os bens, exceto rádio e linha telefônica no período. A correlação dos bens com o Indicador Econômico Nacional reduziu com o tempo. O escore aumentou, com consequente incremento nos pontos de corte dos quintis, mas a distância entre os pontos não teve variação importante. Assim, os pontos de corte de referência publicados para Pelotas rapidamente ficaram desatualizados. Alguns bens perderam a capacidade discriminatória e os pontos de corte ficaram obsoletos rapidamente. É essencial um indicador de bens padronizado para uso em pesquisa, que seja atualizado com frequência, em especial os pontos de corte da distribuição de referência.

The main applications for DORIS are precise orbit determination, and precise Geodesy. Onboard Jason-2 for instance, the DORIS tracking component is the French contribution to the precise orbit determination capability, a key capability for altimetry product scientific result accuracy. T2L2 is a time transfer technique based on the propagation of light pulses for synchronization between two clocks. Hosting T2L2 on-board Jason-2 was to allow for very fine DORIS USO (Ultra-Stable Oscillator) frequency monitoring, and for this purpose T2L2 was connected to the DORIS USO. Thanks to the continuous tracking of T2L2/Jason-2 by the Laser Ranging network it is possible to monitor the USO for several days, weeks, and even much longer, and thus to also compare with the DIODE (the DORIS on-board orbit determination software) frequency bias estimates. The DORIS USO frequency biases estimate comparison between two independent systems, T2L2 and DIODE, can be of benefit to both, allowing the accuracies of both systems to be better understood, and for improvements to be made to both systems. Such comparison is the central topic of the present paper. T2L2 monitors the DORIS on-board USO frequency with an accuracy of much better than 10-12 which is the specification for the Doppler instrumentation. The paper investigates the limits of the DORIS-DIODE frequency bias estimates using T2L2, showing that USO frequency compliance accuracy of 10-12 has been reached.

Research is a main element for human and social development. Under this point of view, it involves particular challenges and opportunities for the so-called "developing countries". An approach for those challenges and opportunities comes from the analysis of two interrelated activities; the training of new researchers and the research development with institutions or researchers which are external to the institution ("collaborative research"). Both activities are essential for the consolidation, widening and updating of the institutional capabilities for scientific production. We present here the experiences of the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia, in relation to the training of new researchers, we discuss the four elements we consider key for this process; the promotion of stimulating environments for research, the proactive identification of fellows, the complementary advice and networks consolidation; and we analyze three successful models of international collaboration for the training of new researchers under different institutional approaches.

To celebrate the 60th anniversary of Medicina (Buenos Aires) an International Symposium was held at the National Academy of Medicine of Buenos Aires on the 6-7th of October 1999, under the title of Clinical investigation in the next millennium. This meeting was a success as evidenced by the 376 registered attendants. Sixty years of uninterrupted publication is an uncommon feat in our midst and this could be achieved on the basis of a number of factors which include, the initiative of those who founded the journal, the unfailing motivation and dedication of the Editorial Board and primarily the authors who have trusted us with their manuscripts. Of the many important papers published, we have selected a few which proved to be milestones in the development of Argentine biomedicine. It is to be hoped that the future will bring an increase in our impact index through more and even better papers eventually reflecting the authentic scientific value of our country.

The decision-making process includes a series of activities undertaken in biomedical journals from the moment a manuscript is received until it is accepted or rejected. Firstly, the manuscript is evaluated by the members of the Editorial Board, who analyze both its suitability for the journal and its scientific quality. After this initial evaluation, the article is evaluated by peer reviewers, an essential process to guarantee its scientific validity. Both the Editorial Board and the peer reviewers usually use checklists which are of enormous help in this task. Once the biomedical article has been accepted, the publication process is started, which in turn includes a series of steps, beginning with technical and medical review of the article's contents and ending with the article's publication in the journal. The present article provides a detailed description of the main technical and ethical issues involved in the processes of decision-making and publication of biomedical articles.

Escola Paulista de Medicina (EPM) was founded in 1933 and the first Professor of Neurology was Fausto Guerner, who could not effectively assume the teaching activities due to his premature death in 1938. Professor Guerner had had his neurological training at Paris. Professor Longo was his successor. Longo was one of the founders of Arquivos de Neuro-Psiquiatria the foremost journal of neurosciences in Latin American. Longo died in 1967 and Professor Paulo Pupo succeeded him. Pupo introduced electroencephalography in Brazil. After his death in 1970, Professor Dante Giorgi succeeded him until 1974. Professor José Geraldo Camargo Lima took over the position after Giorgi's death. He created the Neurological Emergency unit, initiated the Post-Graduation in Neurology and divided the Discipline in specialized units. During the 1980's and until his retirement in 1995, EPM had become one of most important centers of Brazil training neurologists and researchers in neurological sciences.

Relaciones entre el sueño y la adicción

Resumen La interacción entre los trastornos del sueño y el abuso de sustancias es ya conocida, pero seguramente más compleja de lo que se pensaba. Existe tanto una relación positiva entre tener un trastorno por uso de substancias y sufrir un trastorno de sueño, como viceversa. Los efectos sobre el sueño dependen de la substancia utilizada, pero se ha demostrado que tanto durante su uso como en período de abstinencia los consumidores tienen diferentes problemas de sueño y fundamentalmente un sueño más fragmentado. Sabemos que hay que tener en cuenta los problemas de sueño para evitar recaídas en la adicción. Investigaciones recientes indican que el sistema hipocretinérgico definido por el neuropéptido hipocretina/orexina (Hcrt/ox), localizado en el hipotálamo lateral e implicado entre otros en la regulación del ciclo sueño-vigilia, jugaría un papel importante en las conductas adictivas. Diferentes estudios han demostrado interacciones entre el sistema hipocretinérgico, los circuitos de respuesta aguda al estrés y los sistemas de recompensa. También sabemos que la activación optogenética selectiva del sistema hipocretinérgico incrementa la probabilidad de la transición del sueño a la vigilia, y también es suficiente para iniciar un comportamiento compulsivo de recaída adictiva. La activación del sistema hipocretinérgico podría explicar la hipervigilia asociada al estrés y a la adicción. El mayor conocimiento de esta interacción permitiría entender mejor los mecanismos de la adicción y encontrar nuevas estrategias para el tratamiento de las adicciones. PMID:23241715

Obstructive sleep apnea (OSA) has been associated with oxidative stress and various cardiovascular consequences, such as increased cardiovascular disease risk. Quantitative real-time PCR is frequently employed to assess changes in gene expression in experimental models. In this study, we analyzed the effects of chronic intermittent hypoxia (an experimental model of OSA) on housekeeping gene expression in the left cardiac ventricle of rats. Analyses via four different approaches-use of the geNorm, BestKeeper, and NormFinder algorithms; and 2-ΔCt (threshold cycle) data analysis-produced similar results: all genes were found to be suitable for use, glyceraldehyde-3-phosphate dehydrogenase and 18S being classified as the most and the least stable, respectively. The use of more than one housekeeping gene is strongly advised. RESUMO A apneia obstrutiva do sono (AOS) tem sido associada ao estresse oxidativo e a várias consequências cardiovasculares, tais como risco aumentado de doença cardiovascular. A PCR quantitativa em tempo real é frequentemente empregada para avaliar alterações na expressão gênica em modelos experimentais. Neste estudo, analisamos os efeitos da hipóxia intermitente crônica (um modelo experimental de AOS) na expressão de genes de referência no ventrículo cardíaco esquerdo de ratos. Análises a partir de quatro abordagens - uso dos algoritmos geNorm, BestKeeper e NormFinder e análise de dados 2-ΔCt (ciclo limiar) - produziram resultados semelhantes: todos os genes mostraram-se adequados para uso, sendo que gliceraldeído-3-fosfato desidrogenase e 18S foram classificados como o mais e o menos estável, respectivamente. A utilização de mais de um gene de referência é altamente recomendada.

Schistosomiasis is a parasite that is carried by freshwater snails. The intestinal form infects the intestine, liver and spleen and can be fatal. The objective of this review was to assess the effects of oxamniquine or praziquantel for treating Schistosomiasis mansoni We searched the Cochrane Infectious Diseases Group trials register, the Cochrane Controlled Trials Register, Medline, Lilacs and reference lists of articles. The Revista da Sociedade Brasileira de Medicina Tropical and Brazilian Tropical Medicine Congress abstracts were handsearched Randomised and quasi-randomised trials comparing oxamniquine and/or praziquantel to placebo for the treatment of Schistosomiasis mansoni. Two reviewers independently assessed trial quality and extracted data. Thirteen trials met the inclusion criteria. Praziquantel and oxamniquine were effective in curing Schistosoma mansoni infection when compared to placebo. In Africa, praziquantel 40 mg/Kg is more effective than oxamniquine 15 mg/Kg in individuals older than 14 years (OR 3.54, 95%CI 1.70, 7.38), but no difference was found when compared with oxamniquine 30 mg/Kg (OR 0.29, 95%CI 0.08, 1.01). In Brazil, praziquantel was equally effective when compared with oxamniquine in individuals older than 14 years (OR 1.70, 95%CI 0.83, 3.49). Both drugs appear safe. There was no difference in reinfection rate between zinc supplementation and placebo (OR 0.82, 95%CI 0.47, 1.41). IPraziquantel and oxamniquine both appear to be effective for the treatment of Schistosomiasis mansoni, although lower doses of oxamniquine (less than 30 milligrams per kilogram) may not be as effective.

To evaluate self-esteem and body image in patients with venous leg ulcers (VLUs). A multicenter, prospective, descriptive, analytical, clinical study. A nursing care and education center of a university hospital, a health center, and an outpatient wound care clinic in Brazil. Fifty-nine consecutive adult patients with VLUs and Doppler ankle-brachial index ranging from 0.8 to 1.0 were recruited for the study. Exclusion criteria were mixed ulcers, arterial ulcers, and diabetic foot ulcers. A questionnaire assessing sociodemographic and clinical characteristics of patients, the Brazilian version of the Body Investment Scale, and the Rosenberg Self-esteem (RSE)/UNIFESP-EPM (São Paulo da Universidade Federal de São Paulo-Escola Paulista de Medicina) scale were administered to all patients. Most participants were women, aged between 60 and 70 years, and smokers; 33 (56%) were divorced, widowed, or single, and 26 (44%) were married. The patients had the ulcer for a mean of 5.42 years. Exudate and foul odor were present in most cases. Twenty-one ulcers (36%) measured 29 cm or less in surface area, and 17 (29%) ulcers measured between 30 and 49 cm (mean, 3.39 cm). The mean RSE score was 22.66, indicating low self-esteem. The mean Body Investment Scale total score was 27.49, and the scores on the body image and body touch subscales were also low, indicating negative feelings about the body. Patients with VLUs had low self-esteem and negative feelings about their bodies.

An open randomized clinical trial was developed at Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) in Recife and at Petronila Campos Municipal Hospital in São Lourenço da Mata, both in Pernambuco, northeastern Brazil, including 226 low-risk pregnant women bearing a single, full-term, live fetus after delayed cord clamping, 113 randomized to placental cord drainage and 113 to a control group not submitted to this procedure. Women incapable of understanding the study objectives and those who went on to have an instrumental or cesarean delivery were excluded. Duration of the third stage of labor did not differ between the two groups (14.2±12.9 versus 13.7±12.1 minutes (mean ± SD), p = 0.66). Likewise, there was no significant difference in mean blood loss (248±254 versus 208±187ml, p = 0.39) or in postpartum hematocrit levels (32.3±4.06 versus 32.8±4.25mg/dl, p = 0.21). Furthermore, no differences were found between the groups for any of the secondary outcomes (postpartum hemorrhage >500 or >1000ml, therapeutic use of oxytocin, third stage >30 or 60 minutes, digital evacuation of the uterus or curettage, symptoms of postpartum anemia and maternal satisfaction). Placental cord drainage had no effect in reducing duration or blood loss during the third stage of labor. ClinicalTrials.gov: www.clinicaltrial.gov, NCT01655576.

Interventional treatment of coronary insufficiency is underemployed among dialysis patients. Studies confirming its efficacy in this set of patients are scarce. To assess the results of interventional treatment of coronary artery disease in patients undergoing dialysis. A total of 34 dialysis patients submitted to coronary angiography between September 1995 and October 2004 were divided according to presence or absence of coronary lesion, type of treatment and presence or absence of diabetes mellitus. The groups were compared according to their clinical and survival characteristics. Survival of patients undergoing interventional treatment was compared to overall survival of 146 dialysis patients at the institution in the same period. Interventional treatment was indicated to the same clinical conditions in the general population. Thirteen patients with no angiography coronary lesions presented a survival rate of 100% in 48 months as compared to 35% of 21 patients with coronary artery disease. Diabetic patients had a lower survival rate compared with non-diabetics. Angioplasty had a worse prognosis compared to surgery; however, 80% of patients undergoing angioplasty were diabetic. Seventeen patients submitted to interventional procedures presented a survival rate similar to that of the others 146 hemodialysis patients without clinical evidence of coronary disease. This small series shows that myocardial revascularization, whenever indicated, can be performed in dialysis patients. This conclusion is corroborated by similar mortality rates in two groups of patients: coronary patients submitted to revascularization and overall dialysis patients.

The NIDA Clinical Trials Network trial of rapid HIV testing/counseling in 1281 patients was a unique opportunity to examine relationships among substance use, depressive symptoms, and sex risk behavior. Past 6-month substance use; substance use severity (Drug Abuse Screening Test - 10); depressive symptoms (Quick Inventory of Depressive Symptomatology); and three types of sex risk behavior (unprotected sex occasions [USOs] with primary partners; USOs with nonprimary partners; and USOs while high/drunk) were assessed. Zero-inflated negative binomial analyses provided: probability and rate of sex risk behavior (in risk behavior subsample). Levels of sexual risk behavior were high, while variable across the three types of sex risk behaviors. Among the patients, 50.4% had engaged in USOs with primary partners, 42% in sex while drunk or high, and 23.8% in USOs with nonprimary partners. Similar factors were significantly associated with all three types of sex risk behaviors. For all types, problem drinking, cocaine use, and substance use severity had an exacerbating effect. Older age was associated with lower risk behavior; other relationship categories (eg, married, separated/divorced, cohabitating) were associated with greater risk behavior than was single status. Depressive symptoms were associated with decreased likelihood of USOs with a primary partner. Sexual risk behavior is common among individuals in outpatient substance abuse treatment. Results highlight problem drinking (eg, up to three-fold) and cocaine (eg, up to twice) in increasing sex risk behavior. They demonstrate the utility of distinguishing between partner types and presence/absence of alcohol/drugs during sex. Findings argue for the need to integrate sex risk reduction into drug treatment.

Study and optimization of the macroscopic electrical response of carbon based nanocomposites for advanced applications

NASA Astrophysics Data System (ADS)

Silva, Jaime Pedro Oliveira da

A presente tese centrou-se no estudo da resposta da constante dieletrica e condutividade eletrica em materiais compositos nos quais o reforco tinha uma elevada proporcao entre comprimento e diametro. O objeto de estudo foi o efeito de um reforco com uma elevada razao entre comprimento e diametro, concentracao e orientacao na resposta eletrica e dieletrica de um composito. Estes compositos tem uma grande importancia no desenvolvimento de materiais para sensores e atuadores. Num primeiro momento da dissertacao, explorou-se a resposta da constante dieletrica de um composito constituido por nanotubos de carbono como reforco e uma matriz polimerica. Verificou-se que um aumento da razao entre comprimento e diametro do reforco tem o efeito de aumentar a constante dieletrica do composito para uma igual fracao volumetrica de reforco. Constatou-se tambem que materiais na fase nematica demonstram uma constante dieletrica mais baixa quando comparados com materiais onde o reforco esta distribuido aleatoriamente. Ficou ainda demonstrado nesta dissertacao que materiais na fase nematica com razoes entre o comprimento e diametro diferentes a constante dieletrica segue uma lei de potencia. Numa segunda fase do trabalho, foi explorada a condutividade de nanocompositos polimericos reforcados com nanotubos de carbono, atraves de um modelo baseado em cilindros impenetraveis. Ficou demonstrado que o modelo e apropriado para descrever a condutividade eletrica de um nanocomposito polimerico reforcado com nanotubos. As simulacoes desenvolvidas demonstram que, aumentando a razao entre o comprimento e o diametro dos nanotubos de carbono, aumenta a condutividade eletrica do nanocomposito. No entanto, verifica-se que aumentando a anisotropia diminui a condutividade, sendo este efeito mais evidente para fracoes volumetricas maiores. Nesta dissertacao comprovou-se ainda que uma microestrutura gerada por um algoritmo de empacotamento sequencial pode ser descrita por um grafo aleatorio e que a condutividade num composito reforcado com nanofibras de carbono pode ser descrito por uma rede de Bethe. Atraves do uso da teoria das redes complexas, chegou-se a uma expressao para o limite de percolacao e, do mesmo modo, demonstrou-se que “hopping” entre fibras adjacentes resulta numa expressao que corresponde a um regime de desordem fraca. No trabalho desenvolvido tambem foi calculado os expoentes criticos, atraves da teoria das redes, para um sistema 3D composto por cilindros impenetraveis com uma interacao de curto alcance, demonstrando que os expoentes criticos estao relacionados por uma relacao de hiperescala comum para 3D e nao pertencem a mesma classe de universalidade como a percolacao numa rede. A aplicacao do modelo desenvolvido a compositos de epoxy reforcada, com diferentes metodos de dispersao de nanofibras de carbono, revelou que os metodos de dispersao usados para preparar os compositos tem uma forte influencia nas propriedades eletricas que podem ser capturadas pelo modelo. Neste contexto, ficou ainda demonstrado que a condutividade eletrica pode ser descrita por um regime de desordem fraca, isto ´e, um regime onde todas as conexoes fibra-fibra participam na condutividade do composito. O modelo desenvolvido foi aplicado igualmente a compositos de poly (vinylidene fluoride) reforcado com nanotubos de carbono com diferentes tratamentos de termicos de oxidacao. Verificou-se que os tratamentos de superficie aumentam o limite de percolacao e diminuem a condutividade. Nesta dissertacao provamos ainda que a condutividade do composito pode ser atribuida a um mecanismo de “hopping”, fortemente afetado pelos tratamentos de superficie dos reforcos.

This study is a review of the problem of educational formation in terms of an international context, and determinant factors of this need are analyzed, barriers or limitations that have prevented such a formation are highlighted, and some development proposals for educational training are offered. It is also a description of the actions that the Facultad de Medicina (Medical School) of the Universidad Nacional Autónoma de México (National Autonomous University of Mexico) implemented from 1965 to 1996 to promote educational training. In 1997, the Diplomado en Enseñanza de la Medicina began as a new possibility for educational training. The first certification course ran in 1997, and there have been 18 courses to date, eight the Medical School and 10 at external institutions. In 1999, a follow-up questionnaire was answered by physicians trained under the certification program. Results showed that training received in the certification course had a positive effect on teaching skills of physicians who attended it, thus establishing the program as a good option for medical teachers.

[Genealogy of the Books of Practica medicinae in Europe before the End of 18th Century: From the Origin to the Disappearance].

PubMed

Sakai, Tatsuo

2015-09-01

The Practica medicinae represented the books written in Europe before the end of 18th century that dealt with individual deseases. In total, 100 Practica books, written by 95 authors, were collected and divided into four periods from the early 11th to the end of 18th century. The first Practica book was written at the Salernitan medical school on the basis of ancient medical books in the basic style, dealing with regional deseases arranged in "a capite ad calcem" manner, as well as with the fevers. The basic style comprised a majority in the first period and decreased gradually, becoming a minority in the 3rd and 4th periods. Sennert's practica was the largest and it elaborated with precise construction. The additional categories, such as female, children, and surgical deseases increased in the later periods. Those written in non-basic style based on pathogenesis or in alphabetical order also increased in the later periods. The practica books changed slightly and gradually, indicating the essential consistency of the concepts of diseases in these periods.

We present the first field test of the implementation of a coherent optical fiber link for remote antenna synchronization realized in Italy between the Italian Metrological Institute (INRIM) and the Medicina radio observatory of the National Institute for Astrophysics (INAF). The Medicina VLBI antenna participated in the EUR137 experiment carried out in September 2015 using, as reference systems, both the local H-maser and a remote H-maser hosted at the INRIM labs in Turin, separated by about 550 km. In order to assess the quality of the remote clock, the observed radio sources were split into two sets, using either the local or the remote H-maser. A system to switch automatically between the two references was integrated into the antenna field system. The observations were correlated in Bonn and preliminary results are encouraging since fringes were detected with both time references along the full 24 hours of the session. The experimental set-up, the results, and the perspectives for future radio astronomical and geodetic experiments are presented.

Intrasite motions and monument instabilities at Medicina ITRF co-location site

2013-03-01

We process the total-station surveys performed at the ITRF co-location site Medicina (Northern Italy) over the decade (2001-2010) with the purpose of determining the extent of local intrasite motions and relating them to local geophysical processes, the geological setting and the design of the ground pillars. In addition, continuous observations acquired by two co-located GPS stations (MEDI and MSEL separated by ≈27 m) are analysed and their relative motion is cross-checked with the total-station results. The local ground control network extends over a small area (<100 × 100 m) but the results demonstrate significant anisotropic deformations with rates up to 1.6 mm a-1, primarily horizontal, a value comparable to intraplate tectonic deformations. The results derived from GPS and total-station observations are consistent and point to the presence of horizontal intrasite motions over very short distances possibly associated with varying environmental conditions in a very unfavourable local geological setting and unsuitable monument design, these latter being crucial aspects of the realization and maintenance of global permanent geodetic networks and the global terrestrial reference frame.

Novel materials based on chitosan, its derivatives and cellulose fibres

NASA Astrophysics Data System (ADS)

Fernandes, Susana Cristina de Matos

O presente trabalho tem como principal objectivo o desenvolvimento de novos materiais baseados em quitosano, seus derivados e celulose, na forma de nanofibras ou de papel. Em primeiro lugar procedeu-se a purificacao das amostras comerciais de quitosano e a sua caracterizacao exaustiva em termos morfologicos e fisicoquimicos. Devido a valores contraditorios encontrados na literatura relativamente a energia de superficie do quitosano, e tendo em conta a sua utilizacao como precursor de modificacoes quimicas e a sua aplicacao em misturas com outros materiais, realizou-se tambem um estudo sistematico da determinacao da energia de superficie do quitosano, da quitina e seus respectivos homologos monomericos, por medicao de ângulos de contacto Em todas as amostras comerciais destes polimeros identificaram-se impurezas nao polares que estao associadas a erros na determinacao da componente polar da energia de superficie. Apos a remocao destas impurezas, o valor da energia total de superficie (gs), e em particular da sua componente polar, aumentou consideravelmente. Depois de purificadas e caracterizadas, algumas das amostras de quitosano foram entao usadas na preparacao de filmes nanocompositos, nomeadamente dois quitosanos com diferentes graus de polimerizacao, correspondentes derivados soluveis em agua (cloreto de N-(3-(N,N,N-trimetilamonio)-2- hidroxipropilo) de quitosano) e nanofibras de celulose como reforco (celulose nanofibrilada (NFC) e celulose bacteriana (BC). Estes filmes transparentes foram preparados atraves de um processo simples e com conotacao 'verde' pela dispersao homogenea de diferentes teores de NFC (ate 60%) e BC (ate 40%) nas solucoes de quitosano (1.5% w/v) seguida da evaporacao do solvente. Os filmes obtidos foram depois caracterizados por diversas tecnicas, tais como SEM, AFM, difraccao de raio-X, TGA, DMA, ensaios de traccao e espectroscopia no visivel. Estes filmes sao altamente transparentes e apresentam melhores propriedades mecânicas e maior estabilidade termica do que os correspondentes filmes sem reforco. Outra abordagem deste trabalho envolveu o revestimento de folhas de papel de E. globulus com quitosano e dois derivados, um derivado fluorescente e um derivado soluvel em agua, numa maquina de revestimentos ('maquina de colagem') a escala piloto. Este estudo envolveu inicialmente a deposicao de 1 a 5 camadas do derivado de quitosano fluorescente sobre as folhas de papel de forma a estudar a sua distribuicao nas folhas em termos de espalhamento e penetracao, atraves de medicoes de reflectância e luminescencia. Os resultados mostraram que, por um lado, a distribuicao do quitosano na superficie era homogenea e que, por outro lado, a sua penetracao atraves dos poros do papel cessou apos tres deposicoes. Depois da terceira camada verificou-se a formacao de um filme continuo de quitosano sobre a superficie do papel. Estes resultados mostram que este derivado de quitosano fluorescente pode ser utilizado como marcador na optimizacao e compreensao de mecanismos de deposicao de quitosano em papel e outros substratos. Depois de conhecida a distribuicao do quitosano nas folhas de papel, estudou-se o efeito do revestimento de quitosano e do seu derivado soluvel em agua nas propriedades finais do papel. As propriedades morfologicas, mecânicas, superficiais, opticas, assim como a permeabilidade ao ar e ao vapor de agua, a aptidao a impressao e o envelhecimento do papel, foram exaustivamente avaliadas. De uma forma geral, os revestimentos com quitosano e com o seu derivado soluvel em agua tiveram um impacto positivo nas propriedades finais do papel, que se mostrou ser dependente do numero de camadas depositadas. Os resultados tambem mostraram que os papeis revestidos com o derivado soluvel em agua apresentaram melhores propriedades opticas, aptidao a impressao e melhores resultados em relacao ao envelhecimento do que os papeis revestidos com quitosano. Assim, o uso de derivados de quitosano soluveis em agua em processos de revestimento de papel representa uma estrategia bastante interessante e sustentavel para o desenvolvimento de novos materiais funcionais ou na melhoria das propriedades finais dos papeis. Por fim, tendo como objectivo valorizar os residuos e fraccoes menos nobres da quitina e do quitosano provenientes da industria transformadora, estes polimeros foram convertidos em poliois viscosos atraves de uma reaccao simples de oxipropilacao. Este processo tem tambem conotacao "verde" uma vez que nao requer solvente, nao origina subprodutos e nao exige nenhuma operacao especifica (separacao, purificacao, etc) para isolar o produto da reaccao. As amostras de quitina e quitosano foram pre-activadas com KOH e depois modificadas com um excesso de oxido de propileno (PO) num reactor apropriado. Em todos os casos, o produto da reaccao foi um liquido viscoso composto por quitina ou quitosano oxipropilados e homopolimero de PO. Estas duas fraccoes foram separadas e caracterizadas.

To show the way to reach and stay in note 6 in the evaluation process of Medicine III of CAPES. Capes determinations were reviewed concerning this topic, grades 6 and 7, and also the difficulties and facilities of running a program that amounted to Note 6 after restructuring and being in compliance with regulations. The main points to achieve and maintain Note 6 were: 1) regular production of master's and doctoral theses with appropriate distribution among all teachers; 2) average time of appropriate titration, as well as strict selection of students who resets the withdrawals and cancellations; 3) production of scientific articles in high impact journals and with academic and student participation in most part; 4) progressive and substantial increase in fundraising and patent search; 5) progressive increase in international exchanges with joint production; 6) visibility through new bilingual website and updated weekly; 7) numerous solidarity activities in research, but also in health services for the population and even in basic education; 8) rigorous selection of students (through design analysis, curriculum and teacher training program); 9) maintenance of high levels teachers production; 10) preparing new teachers for guidance through participation as co-supervision and involvement in the program to fit the needs. The Postgraduate Program in Translational Surgery went through difficult times; was submitted to a series of measures, adjustments, cooperation and understanding of the teaching staff, that took the program from note 3 - and almost closing - to a level of excellence keeping note 6 for three consecutive three-year periods of evaluation. Mostrar o caminho para alcançar e se manter na nota 6 no processo de avaliação da Medicina III da Capes. Foram revisadas as determinações da Capes concernentes ao tema, conceitos 6 e 7, e também as dificuldades e facilidades próprias da execução de um programa que ascendeu à nota 6 após reestruturação e adequação às normas vigentes. Os pontos principais para alcançar e manter conceito 6 foram: : 1) produção regular de teses de mestrado e doutorado com distribuição adequada entre todos os orientadores; 2) tempo médio de titulação adequado, assim como rígida seleção do alunado que zera as desistências e cancelamentos; 3) produção de artigos científicos alta em revistas de impacto e com participação docente e discente na sua grande maioria; 4) aumento progressivo e substancial da captação de recursos e busca de patentes; 5) aumento progressivo dos intercâmbios internacionais com produção conjunta; 6) visibilidade através de novo site bilíngue e atualizado semanalmente; 7) inúmeras atividades de solidariedade em pesquisa, mas também em Serviços de Saúde para a população e mesmo no ensino básico; 8) rigorosa seleção dos alunos (através de análise de projeto, currículo e programa de estágio docente); 9) manutenção de índices elevados de produção dos docentes; 10) preparação de novos docentes para orientação através de participação como co-orientação e envolvimento no programa para se adequar às necessidades. O Programa de Pós-Graduação em Cirurgia Translacional passou por momentos difíceis e que através de uma série de medidas, ajustes e a colaboração e compreensão do seu corpo docente pode sair da nota 3 e quase fechamento, para um nível de excelência mantendo nota 6 em três triênios seguidos.

To describe and analyse the frequency of the various languages in the bibliographical references from the original articles published in MEDICINA CLINICA during the past 50 years (1945-1995). The languages of publication of 12,807 references from 540 original works published in MEDICINA CLINICA between 1945 and 1995 were determined (at the rate of near 50 articles per year at intervals of five years). The percentage of references in English increased constantly until 1980, but has decreased since then (26.3% in 1945, 42.1% in 1995, 57.7% in 1970, 84.2% in 1980 and 78.5% in 1995). In contrast, the percentage of references in Spanish decreased until 1980, but has increased since then (27.4% in 1945, 18.4% in 1955, 15.8% in 1970, 8.1% in 1980 and 20.0% in 1995). Initially the percentage of references in French remained more or less constant, but decreased markedly from 1970 on ward (23.1% in 1945, 22.5% in 1955, 17.1% in 1970, 5.9% in 1980 and 0.5% in 1995). The percentage of references in German decreased almost continuously during the whole period studied (19.6% in 1945, 10.7% in 1955, 5.8% in 1970, 0.3% in 1980 and 0.3% also in 1995). In 1965, English became the undisputed language of medicine in Spain. The importance of English increased from 1945, then stabilised and even started to decrease in 1980. The importance of Spanish has evolved inversely to that of English, decreasing until 1980 and increasing since that time. The importance of French remained stable until 1970, since when it has decreased, although it continued to be mentioned relatively frequently until 1990. The importance of German decreased constantly from 1945, until this language almost completely disappeared from 1985 onward.

German schools and faculties of veterinary medicine did not receive the sovereign right to award the degree "Doctor medicinae veterinarae" until the early twentieth century. Until then, in the nineteenth century there were two possibilities for veterinarians to earn a doctoral degree, usually referred to as the title of "Doctor": 1. On the basis of an exceptionally excellent dissertation and after very stringent examination a candidate could be awarded the degree "Dr. med." by the faculty of a medical school, or, if the candidate had studied at a philosophical faculty, the degree "Dr. phil." 2. A doctoral degree specifically in veterinary medicine could be earned only at a medical faculty. The Medical Faculty of the University of Giessen awarded the degree "Doctor in arte veterinaria" for the first time in 1832. In this study we prove that Giessen was not the first German university to award a doctorate in veterinary medicine, a priority which has never been questioned in the literature. As early as 1829, veterinarians could earn the degree "Doctor artis veterinariae" at the Medical Faculty of the University of Rostock, where three such awards are documented between 1829 and 1831. The designation "medicina" was also intially avoided in Rostock. Therefore, of particular significance is the discovery of a fourth such document from the Rostock University Archives, the doctoral diploma of Carl Jacob Friedrich Gillmeister, who at the age of 22 was awarded the degree "Doctor medicinae veterinariae" in Rostock after a successful defense. This is the earliest, but also the last archival record of the German doctoral degree in veterinary medicine in the modern sense, because after Gillmeister no veterinarian could earn a doctoral degree in Rostock further more. Gillmeisters vita sheds light on the times and the difficulties of the veterinary profession in the poor agricultural area of Mecklenburg.

Intercontinental Bistatic Radar Test Observation of Asteroid 1998 WT24

We describe the first intercontinental planetary radar test performed in Italy observing the near Earth asteroid (NEA) 33342 (1998 WT24) in December 2001 by means of the bistatic configurations Goldstone (California, USA)-Medicina (Italy) and Evpatoria (Ukraine)-Medicina. The experiment goal was to characterize the system for realtime radar follow-up observations of NEAs and artificial orbiting debris, in the framework of a feasibility study which aims at using the Sardinia Radio Telescope, at present under construction, also as a planetary radar facility. We report the preliminary results of the radar observations carried out by the IRA-CNR (Instituto di Radioastronomia - Consiglio Nazionale delle Ricerche) and the OATo (Osservatorio Astronomico di Torino) groups, aimed at exploring the scientific potentials of a new space radar program, using the existing facilities in Italy. The planetary radar technique is uniquely capable of investigating geometry and surface properties of various solar system objects, demonstrating advantages over the optical methods in its high spatial resolution and ability to obtain three-dimensional images. A single radar detection allows to obtain extremely accurate orbital elements, improving the instantaneous positional uncertainties by orders of magnitude with respect to an optically determined orbit. Radar is a powerful means to spatially resolve NEAs by measuring the distribution of the echo power in time delay (range) and Doppler frequency (line-of-sight velocity) with extreme precision in each coordinate, as it provides detailed information about the target physical properties like size, shape, rotation, near-surface bulk density and roughness and internal density distribution. The Medicina 32m antenna had been successfully used for the first time as the receiving part of a bistatic configuration during a test experiment (September 2001) held to check the capabilities of the entire data acquisition system. This test was possible thanks to the collaboration undertaken with the Evpatoria radar station, and consisted in the observation of the ETALON-1 low orbit satellite

Local effects of redundant terrestrial and GPS-based tie vectors in ITRF-like combinations

Tie vectors (TVs) between co-located space geodetic instruments are essential for combining terrestrial reference frames (TRFs) realised using different techniques. They provide relative positioning between instrumental reference points (RPs) which are part of a global geodetic network such as the international terrestrial reference frame (ITRF). This paper gathers the set of very long baseline interferometry (VLBI)-global positioning system (GPS) local ties performed at the observatory of Medicina (Northern Italy) during the years 2001-2006 and discusses some important aspects related to the usage of co-location ties in the combinations of TRFs. Two measurement approaches of local survey are considered here: a GPS-based approach and a classical approach based on terrestrial observations (i.e. angles, distances and height differences). The behaviour of terrestrial local ties, which routinely join combinations of space geodetic solutions, is compared to that of GPS-based local ties. In particular, we have performed and analysed different combinations of satellite laser ranging (SLR), VLBI and GPS long term solutions in order to (i) evaluate the local effects of the insertion of the series of TVs computed at Medicina, (ii) investigate the consistency of GPS-based TVs with respect to space geodetic solutions, (iii) discuss the effects of an imprecise alignment of TVs from a local to a global reference frame. Results of ITRF-like combinations show that terrestrial TVs originate the smallest residuals in all the three components. In most cases, GPS-based TVs fit space geodetic solutions very well, especially in the horizontal components (N, E). On the contrary, the estimation of the VLBI RP Up component through GPS technique appears to be awkward, since the corresponding post fit residuals are considerably larger. Besides, combination tests including multi-temporal TVs display local effects of residual redistribution, when compared to those solutions where Medicina TVs are added one at a time. Finally, the combination of TRFs turns out to be sensitive to the orientation of the local tie into the global frame.

The study was devised to understand the contribution to nephrology ofDe Medicina Methodicaof Prospero Alpini published in 1511, at a time when the fame of the professor reached the azimuth. We have analyzed the contents of chapters devoted to nephrology in that book of Prospero Alpini and the novelties of his message. Prospero Alpini (1563-1616) taught at the University of Padua (1594-1616), at the same time of Galileo Galilei, Santorio Santorio, and Girolamo Fabrizi dAcquapendente, when measurements (pulse, temperature, perspiration) were introduced into medicine. He was a travelling physician to whom we owe fundamental contributions to the use of urine to prognosticate life and death (De Praesagienda vita et morte aegrotantium libri septem, Venetiis, apud Haeredes Melchioris Sessae,1601). As prefect of the Botanical Garden - the first ever and a model in the world - he could turn the study of simples into cures(De Medicina Methodica Libri Tredecim. Patavi, apud Franciscum Bolzettam, 1611. Ex typographia Laurentij Pasquali, is anin foliovolume of XLVII + 424 pages, 54 lines per page), wherein Alpini aimed to rejuvenate antique medical Methodism. It is a testimony of the interest of medicine philosophers of the modern era for the corpuscular and atomic ideas (Nancy Siraisi). Methodists (2ndCentury BC) refused anatomy and physiology as unique guidelines to the interpretations of diseases and gave importance to the development of a pharmacological science and alternative medicine. The book begins with a 3 page letter to Francis Maria della Rovere Duke of Montefeltro, and a 2 page letter to the readers. We discuss the novelties of the chapters on renal colic (de dolorerenum), hematuria (de sanguinis profluvium), pyuria, anuria (de urina suppressa) and its cure, polyuria (de urina profluvio), renal abscesses, hydrops and its treatment by skin incisions. We also analyze the chapter on kidney and bladder stones (Book X, Chapter XVIII, pp. 354-356) - a masterpiece of scholarly teaching - encompassing localization of stones, their formation and shape, renal colic and its irradiation according to the site and gender, the best antalgic position to pass stones, the use of laxatives, cathartics, warm baths, the plants to be used, their preparation and quality, the waters to be drank and their quantity (up to 15 pounds a day), the removal of bladder stones without surgery (methods learned in Cairo and described in Aegyptyan Medicine), and lithotomy and its feasibility even in old people. De Medicina Methodicawas a modern monograph devoted to clinical medicine including urinary disease. The book reflected the polyhedral personality of the author, his experience as physician of the Republic of Venice at Cairo, and his capabilities as a director of the Botanical Garden of the University of Padua, a unique research centre in those times.

Costruito per chiara volontà del papa 70 anni dopo il caso Galileo, lo Gnomone Clementino è un grande telescopio solare che non fa uso di lenti a 92 anni dall’invenzione del cannocchiale. Queste due caratteristiche basterebbero da sole a giustificare l’interesse verso questo strumento. L’astronomia meridiana è alla base dell’astrometria e dell’astrofisica moderna. Lo Gnomone Clementino sta oggi all’astronomia, come il veliero “Amerigo Vespucci” sta alla Marina Italiana. E’ possibile svolgere ogni genere di osservazione e studio su questo strumento, e dal 2002 vi tengo lezioni teorico-pratiche del corso di Storia dell’Astronomia e La Terra nel Sistema Solare della Sapienza, Università di Roma, Facoltà di Lettere e Filosofia. Questo testo aggiunge alcuni tasselli alla ricerca storica sulla meridiana, appoggiandosi, com’è naturale, sulle spalle di giganti che mi hanno preceduto in questi studi. In particolare la misura dell’azimut della meridiana, ed il suo inquadramento tra gli strumenti simili ed alcuni studi di astrometria sui dati del 1701-1703 di Bianchini, che sono apparsi fin’ora soltanto su riviste specializzate ed in Inglese vengono qui proposti in Italiano e semplificati, per valorizzare sempre più questa straordinaria opera d’arte e di scienza.

The results of a navigation experiment with one way return link Doppler tracking measurements for operational orbit determination of the Cosmic Background Explorer (COBE) spacecraft are presented. The frequency of the tracking signal for the one way measurements was stabilized with an Ultrastable Oscillator (USO), and the signal was relayed by the Tracking and Data Relay Satellite System (TDRSS). The study achieved three objectives: space qualification of TDRSS noncoherent one way return link Doppler tracking; determination of flight performance of the USO coupled to the second generation TDRSS compatible user transponder; and verification of algorithms for navigation using actual one way tracking data. Orbit determination and the inflight USO performance evaluation results are presented.

To analyze the prevalence of current use of oral and injectable contraceptives by Brazilian women, according to demographic and socioeconomic variables and issues related to access to those medicines. A cross-sectional, population-based analytical study with probability sampling based on data from the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), carried out between September 2013 and February 2014 in 20,404 Brazilian urban households. Prevalence was calculated based on reports from non-pregnant women aged 15-49 on the use of oral or injectable contraceptives. The independent variables were gender, age, level of education, socioeconomic class, Brazilian region and marital status. Also analyzed were access, means of payment, sources, and reported medicines. Statistical analyses considered 95% confidence intervals (95%CI) and Pearson Chi-square test to evaluate the statistical significance of differences between groups, considering a 5% significance level. Prevalence of use was 28.2% for oral contraceptives (OC) and 4.5% for injectable contraceptives (IC). The highest prevalence of oral contraceptives was in the South region (37.5%) and the lowest in the North region (15.7%). For injectable contraceptives there was no difference between regions. Access was higher for oral contraceptive users (90.7%) than injectable contraceptives users (81.2%), as was direct payment (OC 78.1%, IC 58.0%). Users who paid for contraceptives acquired them at retail pharmacies (OC 95.0% and IC 86.6%) and at Farmácia Popular (Popular Pharmacy Program) (OC 4.8% and IC 12.7%). Free of charge contraceptives were mostly obtained from the Brazilian Unified Health System - SUS (OC 86.7%; IC 96.0%). Free samples were reported by 10.4% of users who did not pay for oral contraceptives. Most of paying users did not try to obtain contraceptives from SUS. Monophasic combined oral contraceptives were the most frequently reported (71.6%) and low-level levonorgestrel + ethinylestradiol combination accounted for 38.7% of them. The most frequently reported medicines are included in the Relação Nacional de Medicamentos Essenciais (RENAME - National List of Essential Medicines. Most women aged 15 to 49 who reported using contraceptives had access to the medicine and use monophasic combined oral contraceptives of appropriate efficiency and safety purchased by direct payment, mainly from retail pharmacies. Analisar a prevalência do uso atual de contraceptivos orais e injetáveis por mulheres brasileiras, segundo variáveis demográficas, socioeconômicas e aspectos relacionados ao acesso a esses medicamentos. Estudo transversal, analítico, baseado nos dados da Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM), de base populacional e amostra probabilística, realizada entre setembro/2013 e fevereiro/2014, em 20.404 domicílios urbanos brasileiros. A prevalência foi calculada a partir do relato das mulheres de 15 a 49 anos, não grávidas, sobre o uso de contraceptivos orais ou contraceptivos injetáveis. As variáveis independentes foram sexo, idade, escolaridade, nível socioeconômico, região geográfica e situação conjugal. Também foram analisados acesso, fontes de financiamento, fontes de obtenção e medicamentos citados. As análises estatísticas consideraram intervalos de confiança de 95% (IC95%) e teste Qui-quadrado de Pearson para avaliação da significância estatística das diferenças entre os grupos, considerando o nível de significância de 5%. A prevalência de uso de contraceptivos orais (CO) foi 28,2% e de contraceptivos injetáveis (CI), 4,5%. A prevalência de contraceptivos orais foi maior no Sul (37,5%) e menor no Norte (15,7%). Para contraceptivos injetáveis não houve diferença entre as regiões. O acesso foi maior para as usuárias de contraceptivos orais (90,7%) do que de contraceptivos injetáveis (81,2%), assim como o pagamento por desembolso direto (CO 78,1%; CI 58,0%). As usuárias que pagaram pelo contraceptivo compraram na farmácia comercial (CO 95,0% e CI 86,6%) e na Farmácia Popular (CO 4,8% e CI 12,7%). A principal fonte de obtenção gratuita foi o SUS (CO 86,7%; CI 96,0%). Amostra grátis foi citada por 10,4% das usuárias que não pagaram pelos contraceptivos orais. A maioria das usuárias que pagaram, não tentou obter no SUS. Contraceptivos orais combinados monofásico foram os mais citados (71,6%) e a combinação levonorgestrel+etinilestradiol de baixa concentração representou 38,7% destes. Os medicamentos mais citados constam na Relação Nacional de medicamentos Essenciais. A maioria das mulheres entre 15 e 49 anos que referiram usar contraceptivos obteve acesso ao medicamento, usa contraceptivos orais combinados monofásico, de eficácia e segurança adequada, obtido com pagamento do próprio bolso, principalmente, nas farmácias comerciais.

Thomaz, Petronio Generoso; Moura, Leonel Adelino; Muramoto, Giovana; Assad, Renato Samy

2017-01-01

The clinical definition of cardiogenic shock is that of a low cardiac output and evidence of tissue hypoxia in the presence of adequate blood volume. Cardiogenic shock is the main cause of death related to acute myocardial infarction (AMI), with a mortality rate of 45-70% in the absence of aggressive and highly specialized technical care. The intra-aortic balloon pump (IABP) is one of the most widely used mechanical assisting devices. During the last two decades, about 42% of patients with AMI who evolved with cardiogenic shock received mechanical circulatory assistance with IABP. Its clinical indication has been based on non-randomized studies and registry data. Recent studies have shown that the use of IABP did not reduce 30-day mortality in patients with AMI and cardiogenic shock treated with the strategy of early myocardial revascularization as the planned primary objective. The guidelines of the American Heart Association and of the European Society of Cardiology have reassessed their recommendations based on the results of meta-analyzes, including the IABP-SCHOCK II Trial study, which did not evidence an increase in survival of patients who received mechanical support with IABP. This review article addresses the clinical impact of IABP use in the cardiogenic shock caused by AMI. RESUMO A definição clínica de choque cardiogênico é a de um quadro de baixo débito cardíaco e evidência de hipóxia tecidual, na presença de volemia adequada. O choque cardiogênico representa a principal causa de óbito relacionada ao infarto agudo do miocárdio (IAM), com índice de mortalidade em torno de 45% a 70%, na ausência de cuidados técnicos agressivos e altamente especializados. O balão intra-aórtico (BIA) é um dos dispositivos de assistência mecânica mais utilizados no mundo. Nas duas últimas décadas, cerca de 42% dos pacientes com IAM, que evoluíram com choque cardiogênico, receberam assistência circulatória mecânica com BIA. Sua indicação clínica tem sido baseada em estudos não randomizados e dados de registro. Estudos recentes têm demonstrado que o uso do BIA não reduziu a mortalidade hospitalar (30 dias) em pacientes com IAM e choque cardiogênico, tratados com a estratégia de revascularização precoce do miocárdio como objetivo primário planejado. As diretrizes da Associação Americana de Cardiologia e da Sociedade Europeia de Cardiologia reavaliaram suas recomendações, baseadas nos resultados de metanálises, incluindo o estudo IABP-SCHOCK II Trial, que não evidenciou aumento na sobrevida de pacientes que receberam suporte mecânico com BIA. Este artigo de revisão aborda o impacto clínico do uso do BIA no choque cardiogênico ocasionado pelo IAM.

The present work investigates the application of ultrasound and ozone operated individually and in combination with catalyst (ZnO and CuO) for establishing the possible synergistic effects for the degradation of 2,4-dichlorophenol. The dependency of extent of degradation on the operating parameters like temperature (over the range of 30-36°C), initial pH (3-9), catalyst as ZnO (loading of 0.025-0.15g/L) and CuO (loading of 0.02-0.1g/L) and initial concentration of 2,4-DCP (20-50ppm) has been established to maximize the efficacy of ultrasound (US) induced degradation. Using only US, the maximum degradation of 2,4-DCP obtained was 28.85% under optimized conditions of initial concentration as 20ppm, pH of 5 and temperature of 34°C. Study of effect of ozone flow rate for approach of only ozone revealed that maximum degradation was obtained at 400mg/h ozone flow rate. The combined approaches such as US+O 3 , US+ZnO, US+CuO, O 3 +ZnO, O 3 +CuO, US+O 3 +ZnO and US+O 3 +CuO have been subsequently investigated under optimized conditions and observed to be more efficient as compared to individual approaches. The maximum extent of degradation for the combined operation of US+O 3 (400mg/h)+ZnO (0.1g/L) and US+O 3 (400mg/h)+CuO (0.08g/L) has been obtained as 95.66% and 97.03% respectively. The degradation products of 2,4-DCP have been identified using GC-MS analysis and the toxicity analysis has also been performed based on the anti-microbial activity test (agar-well diffusion method) for the different treatment strategies. The present work has conclusively established that the combined approach of US+O 3 +CuO was the most efficient treatment scheme resulting in near complete degradation of 2,4-DCP with production of less toxic intermediates.

To analyze the access to and use of medicines for high blood pressure among the Brazilian population according to social and demographic conditions. Analysis of data from Pesquisa Nacional Sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey on Access, Use and Promotion of Rational Use of Medicines), a nationwide cross-sectional, population-based study, with probability sampling, carried out between September 2013 and February 2014 in urban households in the five Brazilian regions. The study evaluated the access and use of medicines to treat people with high blood pressure. The independent variables were gender, age, socioeconomic status and Brazilian region. The study also described the most commonly used drugs and the percentage of people treated with one, two, three or more drugs. Point estimations and confidence intervals were calculated considering the sample weights and sample complex plan. Prevalence of high blood pressure was 23.7% (95%CI 22.8-24.6). Regarding people with this condition, 93.8% (95%CI 92.8-94.8) had indication for drug therapy and, of those, 94.6% (95%CI 93.5-95.5) were using the medication at the time of interview. Full access to medicines was 97.9% (95%CI 97.3-98.4); partial access, 1.9% (95%CI 1.4-2.4); and no access, 0.2% (95%CI 0.1-0.4). The medication used to treat high blood pressure, 56.0% (95%CI 52.6-59.2) were obtained from SUS (Brazilian Unified Health System), 16.0% (95%CI 14.3-17.9) from Popular Pharmacy Program, 25.7% (95%CI 23.4-28.2) were paid for by the patients themselves and 2.3% (95%CI 1.8-2.9) were obtained from other locations. The five most commonly used drugs were, in descending order, hydrochlorothiazide, losartan, captopril, enalapril and atenolol. Of the total number of patients on treatment, 36.1% (95%CI 34.1-37.1) were using two medicines and 13.5% (95%CI 12.3-14.9) used three or more. Access to medicines for the treatment of high blood pressure may be considered high and many of them are available free of charge. The most commonly used drugs are among those recommended as first-line treatment for high blood pressure control. The percentage of people using more than one drug seems to follow the behavior observed in other countries.

[Scabies and the significance of "suriones" in the handwritten manuscripts of Hildegard von Bingen].

PubMed

Riethe, Peter

2006-01-01

In her studies on nature and medicine, the "Liber simplicis medicinae" (LSM or "Physica") and the "Liber compositae medicinae" (LCM or "Causae et Curae"), Hildegard von Bingen mentions Scabies (mange) in several passages. She characterizes "suren aut (= or) sneuelzen" as the cause of the disease, which she calls also "gracillimi vermiculi", that is, tiny worms that burrow into the human skin ("ubi suren aut sneuelzen hominem comedendo ledunt"). In this context the meanings of the German-ancestor terms "suren aut sneuelzen", which are found in the Latin text concerning the "Alia Mynza", are still disputed. The question whether Hildegard knew the cause of scabies the author discusses on the basis of ancient and medieval sources as well as modem medical historical and philological/linguistic research approaches. He concludes that Hildegard was able not only to describe the symptoms exactly, but also to define the cause of the disease as a special parasite. Consequently, she differentiates other diseases of the skin, such as "grint", from scabies. The proposed interpretation of "sneuelzen" as the tick is untenable. The assumption that both terms are synonyms for sarcoptes scabiei can be confirmed by philological and medical historical research.

"De medicina et morbis" from De rerum naturis by Rabano Mauro.

De rerum naturis from the Monastery of Montecassino (MS codex 132) by Rabano Mauro, is a medieval encyclopedia issued around the year 1025, in the Abbey of Montecassino, during the period of Abbot Teobaldo. It is a copy of a more ancient text, written almost certainly in the Abbey of Fulda 2 centuries before, when Rabano Mauro was the abbot - that is, in the Carolingian age. In the Book 18 there is a chapter entitled "De medicina et morbis," in which we find related the fundamental principles on which studies of the human body, illness and the principal medicinal herbs were based. The text is not intended for teaching the medical art, but has the precise objective of helping to form the cultured Christian, trying to combine the old Greek-Roman tradition with a mystical vision, giving a moral application according to the dictates of Jewish-Christian religion. This text is indicative of the fusion of the scientific and religious worlds in the West during the Middle Ages. This interpretation of the universe will last for about a millennium, and only the Renaissance will be able to separate the 2 worlds again.

Height bias and scale effect induced by antenna gravitational deformations in geodetic VLBI data analysis

NASA Astrophysics Data System (ADS)

Sarti, Pierguido; Abbondanza, Claudio; Petrov, Leonid; Negusini, Monia

2011-01-01

The impact of signal path variations (SPVs) caused by antenna gravitational deformations on geodetic very long baseline interferometry (VLBI) results is evaluated for the first time. Elevation-dependent models of SPV for Medicina and Noto (Italy) telescopes were derived from a combination of terrestrial surveying methods to account for gravitational deformations. After applying these models in geodetic VLBI data analysis, estimates of the antenna reference point positions are shifted upward by 8.9 and 6.7 mm, respectively. The impact on other parameters is negligible. To simulate the impact of antenna gravitational deformations on the entire VLBI network, lacking measurements for other telescopes, we rescaled the SPV models of Medicina and Noto for other antennas according to their size. The effects of the simulations are changes in VLBI heights in the range [-3, 73] mm and a net scale increase of 0.3-0.8 ppb. The height bias is larger than random errors of VLBI position estimates, implying the possibility of significant scale distortions related to antenna gravitational deformations. This demonstrates the need to precisely measure gravitational deformations of other VLBI telescopes, to derive their precise SPV models and to apply them in routine geodetic data analysis.

To study the occurrence and types of neoplasms developed by patients who underwent an orthotopic cardiac transplantation under the Program of Cardiac Transplantation of Escola Paulista de Medicina, Federal University of São Paulo. This is an observational study of 106 patients who underwent orthotopic cardiac transplantation from November 1986 to September 2002 and survived at least thirty days following the procedure. The triple immunosuppressive regimen given included cyclosporin A, azathioprine and a corticosteroid agent. Only two patients received OKT3 in addition to the regimen established. Mean follow-up was 61.4 months (ranging from two months to 192 months). Twenty-three patients (21.3%) developed neoplasms--56.5% of these were skin neoplasm, 30.1%, solid tumors, and 13.4% of post-transplant lymphoproliferative disease (PTLD). Mean interval between transplantation and diagnosis of neoplasm was: 54.9 months for skin neoplasm; 24.8 months for solid tumors and 70.3 months for PTLD. Malignant neoplasms are relatively common in the population studied. Skin cancer was the most common type compared to the other types of neoplasms. Solid tumors were more frequently diagnosed than the lymphoproliferative diseases in the population examined.

2010-07-01

We studied the thermal effects on the 32 m diameter radio-telescope managed by the Institute of Radio Astronomy (IRA), Medicina, Bologna, Italy. The preliminary results show that thermal gradients deteriorate the pointing performance of the antenna. Data has been collected by using: a) two inclinometers mounted near the elevation bearing and on the central part of the alidade structure; b) a non contact laser alignment optical system capable of measuring the secondary mirror position; c) twenty thermal sensors mounted on the alidade trusses. Two series of measurements were made, the first series was performed by placing the antenna in stow position, the second series was performed while tracking a circumpolar astronomical source. When the antenna was in stow position we observed a strong correlation between the inclinometer measurements and the differential temperature. The latter was measured with the sensors located on the South and North sides of the alidade, thus indicating that the inclinometers track well the thermal deformation of the alidade. When the antenna pointed at the source we measured: pointing errors, the inclination of the alidade, the temperature of the alidade components and the subreflector position. The pointing errors measured on-source were 15-20 arcsec greater than those measured with the inclinometer.

Radio transient discovery using next generation radio telescopes will pose several digital signal processing and data transfer challenges, requiring specialized high-performance backends. Several accelerator technologies are being considered as prototyping platforms, including Graphics Processing Units (GPUs). In this paper we present a real-time pipeline prototype capable of processing multiple beams concurrently, performing Radio Frequency Interference (RFI) rejection through thresholding, correcting for the delay in signal arrival times across the frequency band using brute-force dedispersion, event detection and clustering, and finally candidate filtering, with the capability of persisting data buffers containing interesting signals to disk. This setup was deployed at the BEST-2 SKA pathfinder in Medicina, Italy, where several benchmarks and test observations of astrophysical transients were conducted. These tests show that on the deployed hardware eight 20 MHz beams can be processed simultaneously for 640 Dispersion Measure (DM) values. Furthermore, the clustering and candidate filtering algorithms employed prove to be good candidates for online event detection techniques. The number of beams which can be processed increases proportionally to the number of servers deployed and number of GPUs, making it a viable architecture for current and future radio telescopes.

In the context of climate warming, the varying soil moisture caused by precipitation pattern change will affect the applicability of stomatal conductance models, thereby affecting the simulation accuracy of carbon-nitrogen-water cycles in ecosystems. We studied the applicability of four common stomatal conductance models including Jarvis, Ball-Woodrow-Berry (BWB), Ball-Berry-Leuning (BBL) and unified stomatal optimization (USO) models based on summer maize leaf gas exchange data from a soil moisture consecutive decrease manipulation experiment. The results showed that the USO model performed best, followed by the BBL model, BWB model, and the Jarvis model performed worst under varying soil moisture conditions. The effects of soil moisture made a difference in the relative performance among the models. By introducing a water response function, the performance of the Jarvis, BWB, and USO models improved, which decreased the normalized root mean square error (NRMSE) by 15.7%, 16.6% and 3.9%, respectively; however, the performance of the BBL model was negative, which increased the NRMSE by 5.3%. It was observed that the models of Jarvis, BWB, BBL and USO were applicable within different ranges of soil relative water content (i.e., 55%-65%, 56%-67%, 37%-79% and 37%-95%, respectively) based on the 95% confidence limits. Moreover, introducing a water response function, the applicability of the Jarvis and BWB models improved. The USO model performed best with or without introducing the water response function and was applicable under varying soil moisture conditions. Our results provide a basis for selecting appropriate stomatal conductance models under drought conditions. Copyright © 2018 Elsevier B.V. All rights reserved.

Sexual risk behavior is now the primary vector of HIV transmission among substance users in the United States with gender as a crucial moderator of risk behavior. The purpose of this study was to examine gender differences in factors (age, race/ethnicity, education) that predict main-partner unprotected sexual occasions (USO) using the unique platform of two parallel NIDA National Drug Abuse Treatment Clinical Trials Network gender-specific safer sex intervention trials. Baseline assessments of male (N = 430) and female (N = 377) participants included demographic characteristics; past 3-month sexual activity; and a diagnostic assessment for alcohol, cocaine/stimulant, and opioid use disorders. Using mixed effects generalized linear modeling of the main outcome USO, two-way interactions of gender with age, race/ethnicity, and education were evaluated and adjusted by alcohol, cocaine/stimulant, or opioid use disorder. When adjusted for alcohol use disorder, the interaction of education and gender was significant. For men, a high school or greater education was significantly associated with more USO compared to men with less than high school. For women, greater than high school education was significantly associated with less USO compared to women with a high school education. None of the other interactions were significant when adjusted for cocaine/stimulant or opioid use disorder. Conclusions/Importance: This study demonstrates gender differences in the relationship of education, alcohol use disorder, and main-partner USO in individuals in substance abuse treatment. This underscores the importance of considering demographic and substance use factors in HIV sexual risk behavior and in crafting prevention messages for this population.

Evaluation of the criteria for angiotomography indications in the diagnosis of carotid and vertebral arterial injury associated with blunt trauma

PubMed Central

2010-01-01

Background Blunt carotid and vertebral artery injury (BCVI) occur infrequently. The incidence of this type of injury is difficult to determine as many emergency room patients are neurologically asymptomatic. The statistics have not been reported in Brazil. The objectives of the current study were: To evaluate the accuracy of criteria used to recommend angiotomography in the diagnosis of cervical BCVI in 100 patients with blunt cervical trauma in the trauma services section of a Brazilian quaternary care hospital. Methods During a 30-month (2006-2008), all patients admitted to the emergency room of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo with blunt cervical trauma and potential risk of cervical vessel injury, were subjected to cervical angiotomography to diagnose BCVI. The data analyzed are presented as mean ± standard deviation, and statistical analyses included Chi-square and Fisher's exact tests, and the Mann-Whitney test. Results During the study period 2467 blunt trauma patients were admitted. In 100 patients that met the criteria for inclusion in the study, angiotomography identified 23 with BCVI, including 17 males and six females. The mean patient age was 34.81 ± 14.84 years. Car crash (49%) and car-pedestrian accidents (24%) were the most frequent causes of injury. Ten patients had internal carotid artery injuries, two patients had common carotid artery injuries, and 11 patients had vertebral artery injuries. Seven patients presented with Degree I arterial injuries, 10 patients presented with Degree II artery injuries, four patients presented with Degree IV artery injuries, one patient presented with a Degree V artery injury, and one patient had a carotid fistula. Seven out of the 23 patients with BCVI (30.4%) presented with cervical vertebrae fractures, and 11 out of the 23 patients with BCVI (47.8%) presented with facial fractures (LeFort II and III). Conclusions Although there is no consensus regarding the criteria that should be used to indicate angiotomography for BCVI diagnosis, we conclude that the criteria used in the current study led to a diagnosis of BCVI in 0.93% of 2,467 trauma patients, BCVI injuries were associated with more severe traumas and did not affect mortality.

Jawbone reconstruction after tumor resection is one of the most challenging clinical tasks for maxillofacial surgeons. Osteogenic, osteoinductive, osteoconductive and non-antigenic properties of autogenous bone place this bone as the gold standard for solving problems of bone availability. However, the need for a second surgical site to harvest the bone graft increases significantly both the cost and the morbidity associated with the reconstructive procedures. Bone grafting gained an important tool with the discovery of bone morphogenetic proteins in 1960. Benefit of obtaining functional and real bone matrix without need of second surgical site seems to be the great advantage of use bone morphogenetic proteins. This study analyzed the use of rhBMP-2 in unicystic ameloblastoma of the mandible, detailing its structure, mechanisms of cell signaling and biological efficacy, in addition to present possible advantages and disadvantages of clinical use of rhBMP-2 as bone regeneration strategy. RESUMO A reconstrução óssea dos maxilares após ressecções tumorais é uma das tarefas mais difíceis para o cirurgião maxilofacial. As propriedades osteogênicas, osteoindutoras, osteocondutoras e não antigênicas do osso autógeno o colocam como o padrão-ouro para a solução de problemas de disponibilidade óssea. Entretanto a coleta do enxerto ósseo necessita de um segundo sítio cirúrgico, aumentando significativamente o custo e a morbidade associados ao procedimento reconstrutivo. A enxertia óssea ganhou uma excelente ferramenta com a descoberta das proteínas ósseas morfogenéticas na década de 1960. O benefício da obtenção de matriz óssea verdadeira e funcional, sem a necessidade de um segundo sítio cirúrgico, parece ser a grande vantagem do uso das proteínas ósseas morfogenéticas. Neste contexto, o objetivo deste estudo foi analisar a utilização da rhBMP-2 na regeneração óssea de ameloblastoma mandibular unicístico, detalhando sua estrutura, seus mecanismos de sinalização celular e sua eficácia biológica, além de apresentar potenciais vantagens e desvantagens da utilização clínica das rhBMP-2, enquanto estratégia regenerativa.

The study of myocardial viability is of great importance in the orientation and management of patients requiring myocardial revascularization or angioplasty. The technique of delayed enhancement (DE) is accurate and has transformed the study of viability into an easy test, not only for the detection of fibrosis but also as a binary test detecting what is viable or not. On DE, fibrosis equal to or greater than 50% of the segmental area is considered as non-viable, whereas that below 50% is considered viable. During the same evaluation, cardiac magnetic resonance (CMR) may also use other techniques for functional and perfusion studies to obtain a global evaluation of ischemic heart disease. This study aims to highlight the current concepts and broadly emphasize the use of CMR as a method that over the last 20 years has become a reference in the detection of infarction and assessment of myocardial viability. Resumo O estudo de viabilidade miocárdica é de grande importância para a orientação e manejo de pacientes que necessitam de cirurgia de revascularização miocárdica ou angioplastia. A técnica de realce tardio (RT) é precisa e transformou o estudo de viabilidade em um teste fácil, não só para a detecção de fibrose, mas também como um modelo binário para a detecção do que é ou não é viável. Uma fibrose identificada pelo RT é considerada como não viável quando igual ou maior do que 50% da área segmentar e como viável quando menor que 50%. A ressonância magnética cardíaca (RMC) também pode lançar mão de outras técnicas para estudo funcional e de perfusão para uma avaliação global da doença isquêmica do coração no mesmo exame. Este estudo tem como objetivo destacar os conceitos atuais e enfatizar amplamente o uso da RMC como um método que nos últimos 20 anos se tornou referência na detecção de infarto e avaliação de viabilidade miocárdica.

To analyze potential intravenous drug interactions, and their level of severity associated with the administration of these drugs based on the prescriptions of an intensive care unit. Quantitative study, with aretrospective exploratory design, and descriptive statistical analysis of the ICU prescriptions of a teaching hospital from March to June 2014. The sample consisted of 319 prescriptions and subsamples of 50 prescriptions. The mean number of drugs per patient was 9.3 records, and a higher probability of drug interaction inherent to polypharmacy was evidenced. The study identified severe drug interactions, such as concomitant administration of Tramadol with selective serotonin reuptake inhibitor drugs (e.g., Metoclopramide and Fluconazole), increasing the risk of seizures due to their epileptogenic actions, as well as the simultaneous use of Ranitidine-Fentanyl®, which can lead to respiratory depression. A previous mapping of prescriptions enables the characterization of the drug therapy, contributing to prevent potential drug interactions and their clinical consequences. Analisar as potenciais interações medicamentosas intravenosas e seu grau de severidade associadas à administração desses medicamentos a partir das prescrições do Centro de Terapia Intensiva. Estudo quantitativo, tipologia retrospectiva exploratória, com análise estatística descritiva das prescrições medicamentosas do Centro de Terapia Intensiva de um Hospital Universitário, no período de março-junho/2014. A amostra foi composta de 319 prescrições e subamostras de 50 prescrições. Constatou-se que a média de medicamentos por paciente foi de 9,3 registros, e evidenciou-se maior probabilidade para ocorrência de interação medicamentosa inerente à polifarmácia. O estudo identificou interações medicamentosas graves, como a administração concomitante de Tramadol com medicamentos inibidores seletivos da recaptação da serotonina, (exemplo: Metoclopramida e Fluconazol), aumentando o risco de convulsões devido às suas ações epileptogênicas, além do uso simultâneo de Ranitidina-Fentanil®, que pode ocasionar depressão respiratória. O mapeamento prévio das prescrições possibilita a caracterização da terapêutica medicamentosa, contribuindo para obstar as potenciais interações medicamentosas e suas consequências clínicas.

Espera-se que o educando ao final da educação básica, adquira uma compreensão atualizada das hipóteses, modelos e formas de investigação sobre a origem e evolução do Universo em que vive. O presente trabalho tem como principal objetivo compreender dentre três práticas pedagógicas adotadas no Ensino de Astronomia, na terceira série do Ensino Médio, da Escola Estadual Colônia dos Pescadores, qual melhor cumpre o papel de formação e aprendizagem para vida. A pesquisa preliminar foi através de um questionário onde o intuito foi diagnosticar o conhecimento já existente acerca do tema em questão. O questionário é composto de vinte questões dissertativas e objetivas, onde os educandos das três turmas envolvidas o responderam. Este trabalho utiliza as seguintes metodologias: a tradicional, onde o professor é um repassador de informações, fazendo uso exclusivo de lousa e giz; a segunda também de forma tradicional, porém com auxílio de multimídia para desenvolvimento das aulas e aterceira sob forma de seminários, elaborados e apresentados pelos educandos, no qual o educador faz apenas as intervenções necessárias. Ao final do trabalho os alunos responderão novamente o questionário inicial para diagnosticar dentre as três metodologias utilizadas qual apresentou melhor resultado. Os resultados preliminares obtidos, já podem ser observados e, dos 119 alunos entrevistados, as respostas obtidas são as mais diversas e evidenciam que a grande maioria nunca teve em sua vida escolar o tema Astronomia. Ao serem questionados se já haviam estudado Astronomia as respostas foram: turma A: sim 43%; turma B: sim: 21%; turma C: sim: 24%. Porém quando questionados a respeito do significado de Astronomia observou-se que: turma A: 100% de acertos; turma B: 64% acertos; turma C: 84% de acertos, demonstrando claramente a aprendizagem em diferentes esferas, não dependendo unicamente da escola. Até o presente momento, verificou-se que há interesse em estudar o tema Astronom! ia entre os educandos.

A busca por estruturas em grandes escalas (aglomerados de galáxias, por exemplo) é um ativo tópico de pesquisas hoje em dia, pois a detecção de um único aglomerado em altos redshifts pode por vínculos fortes sobre os modelos cosmológicos. Neste projeto estamos fazendo uma busca de estruturas distantes em campos contendo pares de quasares próximos entre si em z Â3 0.9. Os pares de quasares foram extraídos do catálogo de Véron-Cetty & Véron (2001) e estão sendo observados com os telescópios: 2,2m da University of Hawaii (UH), 2,5m do Observatório de Las Campanas e com o GEMINI. Apresentamos aqui a análise preliminar de um par de quasares observado nos filtros i'(7800 Å) e z'(9500 Å) com o GEMINI. A cor (i'-z') mostrou-se útil para detectar objetos "early-type" em redshifts menores que 1.1. No estudo do par 131046+0006/J131055+0008, com redshift ~ 0.9, o uso deste método possibilitou a detecção de sete objetos candidatos a galáxias "early-type". Num mapa da distribuição projetada dos objetos para 22 < i' < 25 observou-se que estas galáxias estão localizadas próximas a um dos quasares e há indícios de que estejam aglomeradas dentro de um área de ~ 6 arcmin2. Se esse for o caso, estes objetos seriam membros de uma estrutura em grande escala. Um outro argumento em favor dessa hipótese é que eles obedecem uma relação do tipo Kormendy (raio equivalente X brilho superficial dentro desse raio), como a apresentada pelas galáxias elípticas em z = 0.

Estimating the incidence rate of pressure ulcers and verifying factors associated with this occurrence in a cohort of hospitalized patients. This is a cohort study in which the considered outcome was the time until pressure ulcer occurrence. Estimated effect of the variables on the cumulative incidence ratio of the outcome was performed using the Cox proportional hazards model. Variable selection occurred via the Logrank hypothesis test. The sample consisted of 442 adults, with 25 incidents of pressure ulcers. Patients with high scores on the Braden scale presented a higher risk of pressure ulcer incidence when compared to those classified into the low score category. These results reinforce the importance of using the Braden Scale to assist in identifying patients more likely to develop pressure ulcers. Estimar a taxa de incidência de úlcera por pressão e verificar fatores associados a essa ocorrência em uma coorte de pacientes hospitalizados. Trata-se de estudo de coorte no qual o desfecho foi a ocorrência da úlcera por pressão. A estimativa do efeito das variáveis para a proporção de incidência acumulada do desfecho foi realizada utilizando o modelo de riscos proporcionais de Cox. A seleção das variáveis ocorreu por meio do teste de hipóteses Logrank. A amostra foi composta de 442 adultos, com 25 casos incidentes de úlcera por pressão. Pacientes com altos escores na escala de Braden apresentaram maior risco de incidência de úlcera por pressão quando comparados com aqueles classificados na categoria de baixo escore. Os resultados reforçam a importância do uso da Escala de Braden para auxiliar na identificação dos pacientes com maior probabilidade de desenvolver úlcera por pressão.

To determine whether the use of a gel pillow with side cutouts designed to accommodate a continuous positive airway pressure (CPAP) mask and reduce head temperature improves the efficacy of and adherence to auto-CPAP therapy. Twenty-three consecutive CPAP-naïve patients with obstructive sleep apnea were enrolled in the study. Patients were given an auto-CPAP machine with an appropriate CPAP mask and were instructed to use CPAP for 15 nights. They were instructed to sleep with their own pillow (the control pillow) from nights 1 to 5 and with either a foam pillow or a gel pillow, both of which had side cutouts, for 5 consecutive nights each, in random order. After night 15, auto-CPAP machine data were downloaded and patients rated their satisfaction with each pillow on a visual analog scale. Twenty-two patients completed the protocol. The pressures administered, residual apnea-hypopnea index, air leaks, and mean duration of CPAP use did not differ among the periods during which each pillow was used. Patients were significantly more satisfied with the gel pillow than with the control pillow and the foam pillow (p = 0.022 and p = 0.004, respectively), their level of satisfaction with the gel pillow correlating significantly with excessive daytime sleepiness (r2 = 0.19; p = 0.0443). Among obstructive sleep apnea patients treated with nasal CPAP, the use of a gel pillow with side cutouts appears to have no impact on treatment effectiveness. Nevertheless, such patients seem to prefer a gel pillow over other types of pillows. Determinar se o uso de um travesseiro de gel com recortes laterais para acomodar a máscara de continuous positive airway pressure (CPAP, pressão positiva contínua nas vias aéreas) e diminuir a temperatura em torno da cabeça melhora a eficácia do tratamento com auto-CPAP e a adesão dos pacientes ao tratamento. Foram incluídos no estudo 23 pacientes consecutivos com apneia obstrutiva do sono que nunca haviam recebido tratamento com CPAP. Os pacientes receberam um aparelho de auto-CPAP com uma máscara apropriada e foram instruídos a usar CPAP durante 15 noites. Foram também instruídos a dormir com seu próprio travesseiro (o travesseiro controle) nas 5 primeiras noites e com um travesseiro de espuma ou um travesseiro de gel, ambos com recortes laterais, durante 5 noites consecutivas cada, em ordem aleatória. Depois da 15ª noite, os dados registrados nos aparelhos de auto-CPAP foram baixados e os pacientes determinaram seu grau de satisfação com cada travesseiro por meio de uma escala visual analógica. Vinte e dois pacientes completaram o protocolo. Não houve diferenças entre os períodos durante os quais cada travesseiro foi usado quanto às pressões administradas, índice de apneia-hipopneia residual, vazamentos de ar e média de duração da CPAP. Os pacientes ficaram significativamente mais satisfeitos com o travesseiro de gel do que com o travesseiro controle e o travesseiro de espuma (p = 0,022 e p = 0,004, respectivamente), com correlação entre o grau de satisfação com o travesseiro de gel e a sonolência diurna excessiva (r2 = 0,19; p = 0,0443). Em pacientes com apneia obstrutiva do sono tratados com CPAP nasal, o uso de um travesseiro de gel com recortes laterais aparentemente não tem nenhum impacto na eficácia do tratamento. No entanto, esses pacientes aparentemente preferem um travesseiro de gel a outros tipos de travesseiros.

The objective of this paper was to characterize the population seen at the dentistry unit of the hematology-oncology service of the Oncology-Hematology Service, Instituto da Criança at the Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo. Oral problems resulting from cancer therapy increase the risk of infection, length of hospital stay, treatment cost and negative impact on the course and prognosis of the disease. Of the 367 medical records of cancer patients seen from November 2007 until December 2008: 186 with a cancer diagnosis and complete clinical data were selected, while 20 with a cancer diagnosis and incomplete records were excluded; 161 medical records with only hematological diagnosis were also excluded. The following characteristics were assessed: ethnicity, gender, age, diagnosis and characteristics of the neoplasm, cancer therapy status and performed dental procedures. Review of 1,236 visits indicated that 54% (n=100) of the patients had blood cancers, 46% (n=86) had solid tumors and 63% were undergoing anticancer therapy. The proportion of males (52.7%) in the study population was slightly greater. The most common cancer was acute lymphocytic leukemia (32.2%). Cancer occurred more often among those patients aged 5 to 9 years. The most common dental procedures were restorative treatment, preventive treatment and removal of infectious foci. The characteristics of the studied population were similar to those of the general Brazilian and global populations, especially regarding gender and diagnosis distributions. The aim of implementation of the dentistry unit was to maintain good oral health and patients' quality of life, which is critical to provide oral care and prevent future oral problems.

INTRODUCTION: A cataract is defined as an opacity of any portion of the lens, regardless of visual acuity. In some advanced cases of cataracts, in which good fundus visualization is not possible, an ultrasound examination provides better assessment of the posterior segment of the globe. OBJECTIVES: This study aims to evaluate the ultrasonographic records of patients with advanced cataracts who were examined during cataract campaigns. METHODS: The ultrasonographic findings obtained from 215 patients examined in cataract campaigns conducted by the Hospital das Clínicas Department of Ophthalmology of the Faculdade de Medicina da Universidade de São Paulo between the years of 2005 and 2007 were evaluated, and the utility of this exam in changing the treatment procedures was studied. RESULTS: A total of 289 eyes from 215 patients were examined. Of the eyes examined, 77.5% presented with findings in the vitreous cavity and the posterior pole. A posterior vitreous detachment with no other complications was observed in 47.4% of the eyes. The remaining 30.1% presented with eye diseases that could result in a reduced visual function after surgery. The most frequent eye diseases observed were diffuse vitreous opacity (12.1% of the eyes) and detachment of the retina (9.3% of the eyes). DISCUSSION: In many cases, the ultrasonographic evaluation of the posterior segment revealed significant anomalies that changed the original treatment plan or contra-indicated surgery. At the very least, the evaluation was useful for patient counseling. CONCLUSION: The ultrasonographic examination revealed and differentiated between eyes with cataracts and eyes with ocular abnormalities other than cataracts as the cause of poor vision, thereby indicating the importance of its use during ocular evaluation.

The concept of a hybrid operating room represents the union of a high-complexity surgical apparatus with state-of-the-art radiological tools (ultrasound, CT, fluoroscopy, or magnetic resonance imaging), in order to perform highly effective, minimally invasive procedures. Although the use of a hybrid operating room is well established in specialties such as neurosurgery and cardiovascular surgery, it has rarely been explored in thoracic surgery. Our objective was to discuss the possible applications of this technology in thoracic surgery, through the reporting of three cases. RESUMO O conceito de sala híbrida traduz a união de um aparato cirúrgico de alta complexidade com recursos radiológicos de última geração (ultrassom, TC, radioscopia e/ou ressonância magnética), visando a realização de procedimentos minimamente invasivos e altamente eficazes. Apesar de bem estabelecido em outras especialidades, como neurocirurgia e cirurgia cardiovascular, o uso da sala hibrida ainda é pouco explorado na cirurgia torácica. Nosso objetivo foi discutir as aplicações e as possibilidades abertas por essa tecnologia na cirurgia torácica através do relato de três casos.

To analyze the determinants for the occurrence of human visceral leishmaniasis linked to the conditions of vulnerability. This is an ecological study, whose spatial analysis unit was the Territorial Analysis Unit in Araguaína, State of Tocantins, Brazil, from 2007 to 2012. We have carried out an analysis of the sociodemographic and urban infrastructure situation of the municipality. Normalized primary indicators were calculated and used to construct the indicators of vulnerability of the social structure, household structure, and urban infrastructure. From them, we have composed a vulnerability index. Kernel density estimation was used to evaluate the density of cases of human visceral leishmaniasis, based on the coordinates of the cases. Bivariate global Moran's I was used to verify the existence of spatial autocorrelation between the incidence of human visceral leishmaniasis and the indicators and index of vulnerability. Bivariate local Moran's I was used to identify spatial clusters. We have observed a pattern of centrifugal spread of human visceral leishmaniasis in the municipality, where outbreaks of the disease have progressively reached central and peri-urban areas. There has been no correlation between higher incidences of human visceral leishmaniasis and worse living conditions. Statistically significant clusters have been observed between the incidences of human visceral leishmaniasis in both periods analyzed (2007 to 2009 and 2010 to 2012) and the indicators and index of vulnerability. The environment in circumscribed areas helps as protection factor or increases the local vulnerability to the occurrence of human visceral leishmaniasis. The use of methodology that analyzes the conditions of life of the population and the spatial distribution of human visceral leishmaniasis is essential to identify the most vulnerable areas to the spread/maintenance of the disease. Analisar determinantes para a ocorrência da leishmaniose visceral humana vinculados às condições de vulnerabilidade. Estudo ecológico, cuja unidade de análise espacial foi a Unidade de Análise Territorial em Araguaína, TO, de 2007 a 2012. Foi realizada análise da situação sociodemográfica e de infraestrutura urbana no município. Indicadores primários normalizados foram calculados e utilizados na construção de indicadores de vulnerabilidade de estrutura social, de estrutura domiciliar e de infraestrutura urbana. A partir deles, foi composto um índice de vulnerabilidade. A estimativa de Kernel foi utilizada para avaliar a densidade de casos de leishmaniose visceral humana, com base nas coordenadas dos casos. O I-Moran Global Bivariado foi empregado para verificar a existência de autocorrelação espacial entre a incidência de leishmaniose visceral humana e os indicadores e índice de vulnerabilidade. I-Moran Local Bivariado foi utilizado para identificar clusters espaciais. Foi observado um padrão de disseminação centrífuga da leishmaniose visceral humana no município, em que surtos da doença atingiram progressivamente áreas centrais e periurbanas. Houve correlação entre maiores incidências de leishmaniose visceral humana e piores condições de vida. Foram observados clusters estatisticamente significativos entre as incidências de leishmaniose visceral humana nos dois períodos analisados (2007 a 2009 e 2010 a 2012) e os indicadores e índice de vulnerabilidade. O ambiente em áreas circunscritas contribui como fator de proteção ou aumenta a vulnerabilidade local à ocorrência de leishmaniose visceral humana. O uso de metodologia que analisa as condições de vida da população e distribuição espacial da leishmaniose visceral humana é essencial na identificação de áreas mais vulneráveis à disseminação/manutenção da doença.

Context Since drug-involved women are among the fastest growing groups with AIDS, sexual risk reduction intervention for them is a public health imperative. Objective Test effectiveness of HIV/STD safer sex skills building (SSB) groups for women in community drug treatment. Design Randomized trial of SSB versus standard HIV/STD Education (HE); assessments at baseline, 3- and 6- months Participants Women recruited from 12 methadone or psychosocial treatment programs in NIDA’s Clinical Trials Network. 515 women with ≥ one unprotected vaginal or anal sex occasion (USO) with a male partner in the past 6 months were randomized. Interventions In SSB, five 90-minute groups used problem-solving and skills rehearsal to increase HIV/STD risk awareness, condom use and partner negotiation skills. In HE, one 60-minute group covered HIV/STD disease, testing, treatment, and prevention information. Main Outcome Number of USOs at follow up. Results A significant difference in mean USOs was obtained between SSB and HE over time (F=67.2, p<.0001). At 3 months, significant decrements were observed in both conditions. At 6 months SSB maintained the decrease, HE returned to baseline (p<.0377). Women in SSB had 29% fewer USOs than those in HE. Conclusions Skills building interventions can produce ongoing sexual risk reduction in women in community drug treatment. PMID:18645513

Hace 80 años, la Escuela de Medicina de la Universidad Nacional, en voz de su director, Gustavo Baz Prada, hizo una propuesta que pronto se convirtió en realidad y finalmente en norma, la que desde entonces se conoce como SS. Esta iniciativa se vio como una manera para que los estudiantes de medicina del último año retribuyeran a la sociedad una parte de lo que esta invirtió en su educación, consolidaran su formación mediante la exposición a las realidades de todos los días en los medios más necesitados, se pusieran a prueba sobre sus verdaderas capacidades para atender pacientes y participaran en la solución de un problema de atención sanitaria que en ese entonces era mucho más apremiante que ahora. Unos años después, los recién egresados de otras licenciaturas (pasantes) también fueron incorporados a esta estrategia y, al fin, se reconoció formalmente como una responsabilidad de las instituciones educativas. Las aportaciones del SS a la salud de las personas y a la formación de los médicos han sido incuestionables, y la experiencia humana que ha representado para quienes lo han vivido ha dejado marcas indelebles.

The presence of water has been considered for a long time as a key condition for life in planetary environments. The Cassini mission discovered water vapour in the Kronian system by detecting absorption of UV emission from a background star (Hansen et al. 2006). Prompted by this discovery, we started an observational campaign for search of another manifestation of the water vapour in the Kronian system, its maser emission at the frequency of 22 GHz (1.35 cm wavelength). Observations with the 32 m Medicina radio telescope (INAF-IRA, Italy) started in 2006 using Mk5A data recording and the JIVE-Huygens software correlator. Later on, an on-line spectrometer was used at Medicina. The 14 m Metsähovi radio telescope (TKK-MRO, Finland) joined the observational campaign in 2008 using a locally developed data capture unit and software spectrometer. More than 300 hours of observations were collected in 2006-2008 campaign with the two radio telescopes. The data were analysed at JIVE using the Doppler tracking technique to compensate the observed spectra for the radial Doppler shift for various bodies in the Kronian system (Pogrebenko et al. 2009). Here we report the observational results for Hyperion, Titan, Enceladus and Atlas, and their physical interpretation. Encouraged by these results we started a campaign of follow up observations including other radio telescopes.

Physical activity is the basic non-pharmacological instrument in the treatment of type 2 diabetes. Nevertheless, only a small number of diabetics take regular physical exercise. One of the reasons why diabetics "do not exercise" is that they have little opportunity to try physical stress under expert supervision and to get to know its effects on, for example, sugar levels. It is a very complex matter to define the optimal intensity of physical activity of, for example, a diabetic who suffers from obesity. In 2001 VSTJ MEDICINA Prague opened its first physical activity centre at the First Faculty of Medicine, Charles University in Prague, in cooperation with the Third Internal Clinic and the Institute of Sports Medicine of the First Faculty of Medicine, Charles University in Prague. It now has over 2000 members, of whom around 60% are patients with metabolic syndrome. Over 150 patients exercise every day under the supervision of expert instructors. The main objective of the Physical Activity Centre is to teach patients the correct principles of physical exercise to enable them to continue carrying out their trainers' instructions at home. A correct understanding of the importance of physical exercise and practical experience under the supervision of experienced instructors improves compliance and has a strong effect on the compensation of diabetes, thereby improving the prognoses of these patients.

Several tests to observe signals transmitted by GLONASS (GLObal NAvigation Satellite System) satellites have been performed using the geodetic VLBI (Very Long Baseline Interferometry) technique. The radio telescopes involved in these experiments were Medicina (Italy) and Onsala (Sweden), both equipped with L-band receivers. Observations at the stations were performed using the standard Mark4 VLBI data acquisition rack and Mark5A disk-based recorders. The goals of the observations were to develop and test the scheduling, signal acquisition and processing routines to verify the full tracking pipeline, foreseeing the cross-correlation of the recorded data on the baseline Onsala-Medicina. The natural radio source 3c286 was used as a calibrator before the starting of the satellite observation sessions. Delay models, including the tropospheric and ionospheric corrections, which are consistent for both far- and near-field sources are under development. Correlation of the calibrator signal has been performed using the DiFX software, while the satellite signals have been processed using the narrow band approach with the Metsaehovi software and analysed with a near-field delay model. Delay models both for the calibrator signals and the satellites signals, using the same geometrical, tropospheric and ionospheric models, are under investigation to make a correlation of the satellite signals possible.

To describe the steps in the transcultural adaptation of the scale in the Effort-reward imbalance model to household and family work to the Brazilian context. We performed the translation, back-translation, and initial psychometric evaluation of the questionnaire that comprised three dimensions: (i) effort (eight items, emphasizing quantitative workload), (ii) reward (11 items that seek to capture the intrinsic value of family and household work, societal esteem, recognition from the spouse/partner, and affection from the children), and (iii) overcommitment (four items related to intrinsic effort). The scale was included in a sectional study conducted with 1,045 nursing workers. A subsample of 222 subjects answered the questionnaire for a second time, seven to 15 days thereafter. The data were collected between October 2012 and May 2013. The internal consistency of the scale was evaluated using Cronbach's alpha and test-retest reliability analysis, square weighted kappa, prevalence and bias adjusted Kappa, and intraclass correlation coefficient. Prevalence and bias-adjusted Kappa (ka) of the scale dimensions ranged from 0.80-0.83 for overcommitment, 0.78-0.90 for effort, and 0.76-0.93 for reward. In most dimensions, the values of minimum and maximum scores, average, standard deviation, and Cronbach's alpha were similar in test and retest scores. Only on societal esteem subdimension (reward) was there little variation in standard deviation (test score of 2.24 and retest score of 3.36) and in Cronbach's alpha coefficient (test score of 0.38 and retest score of 0.59). The Brazilian version of the scale was found to have proper reliability indices regarding time stability, which suggests adapting it to be used in population with characteristics that are similar to the one in this study. Descrever as etapas da adaptação transcultural da escala do Effort-reward imbalance model to household and family work para o contexto brasileiro. Efetuou-se a tradução, retrotradução e avaliação psicométrica inicial do instrumento composto por três dimensões: (i) esforço (oito itens, enfatizando a carga quantitativa de trabalho), (ii) recompensa (11 itens que buscam captar o valor intrínseco da família e do trabalho doméstico, a estima social, o reconhecimento do cônjuge ou companheiro e a afeição dos filhos) e (iii) o excesso de comprometimento (quatro itens relacionados ao esforço intrínseco). A escala foi incluída em um estudo seccional aplicado em 1.045 trabalhadoras de enfermagem. Uma subamostra de 222 participantes respondeu ao questionário pela segunda vez, com intervalo de sete a 15 dias. Os dados foram coletados entre outubro de 2012 e maio de 2013. A consistência interna da escala foi avaliada pelo coeficiente de alpha de Cronbach e a confiabilidade teste-reteste, pelo índice kappa ponderado quadrático, pelo kappa ajustado pela prevalência e pelo coeficiente de correlação intraclasse. A confiabilidade ajustada pela prevalência (ka) das dimensões da escala variou de 0,80-0,83 para o excesso de comprometimento, 0,78-0,90 para o esforço e 0,76-0,93 para a recompensa. Na maioria das dimensões, os valores do escore mínimo e máximo, média, desvio-padrão e alpha de Cronbach no teste e no reteste foram semelhantes. Somente na subdimensão estima social (recompensa) houve pequena variação no desvio padrão (2,24 no teste e 3,36 no reteste) e no coeficiente de alpha de Cronbach (0,38 no teste e 0,59 no reteste). A versão brasileira da escala apresentou índices adequados de fidedignidade quanto à estabilidade temporal, o que sugere a adequação da escala para uso em populações com características semelhantes à do estudo.

It is estimated that there are nearly 40 million people with the human immunodeficiency virus (HIV) worldwide. Due to the advent of antiretroviral drugs, it has been observed increasing in obesity and metabolic rates among patients undergoing treatment. Thus, numerous surgical therapies for weight loss are proposed for continuous improvement in health of patients with HIV, being the vertical gastrectomy an option for intact intestinal transit. To evaluate the applicability of the vertical gastrectomy in patients with morbid obesity and HIV. Was conducted a systematic review of the literature, in the electronic databases Scopus, Pubmed, Cinahl, Scielo, Cochrane and Lilacs, from 1998 to 2015. MeSH headings used in data collection were "Gastrectomy" and "Morbid obesity" being combined with the descriptor "HIV". Were found 2148 articles in Scopus, 1234 in PubMed and 784 in Cinahl. The articles were analyzed by the Jadad Quality Scale, being reduced to 40 articles, subsequently reassessed using an elaborated form by the Critical Appraisal Skills Programme (CASP), reaching 12 articles in the end. It was found that vertical gastrectomy constitutes a safe and effective method, with low mortality and low rate of postoperative complications, being recommended as surgical technique in patients with obesity, HIV and comorbidities. Estima-se que haja quase 40 milhões de pessoas com o vírus da imunodeficiência adquirida (HIV) no mundo. Com o advento dos antirretrovirais, observou-se aumento da obesidade e de taxas metabólicas nos pacientes em tratamento. Assim, inúmeras terapias cirúrgicas para a perda de peso estão sendo estudadas para a melhoria contínua da saúde dos pacientes com HIV, sendo a gastrectomia vertical uma opção de trânsito íntegro. Avaliar a aplicabilidade da gastrectomia vertical em pacientes com obesidade mórbida e HIV.

To describe indicators and processes developed and implemented for pharmaceutical assistance at the Einstein Program at Paraisópolis Community pharmacy. This was a descriptive study of retrospective data from January 2012 to December 2015. Data were obtained from spreadsheets developed for monitoring the productivity and care quality provided at the pharmacy. The evaluated variables were pharmaceutical assistance to prescription, pharmaceutical intervention, orientation (standard and pharmaceutical) and pharmaceutical orientation rate. The pharmacy assisted, on average, 2,308 prescriptions monthly, dispensing 4,871 items, including medications, materials and food supplements. Since March 2015, virtually, the pharmacist analyzed all prescriptions, prior to dispensing. In the analyzed period, there was an increase in monthly pharmaceutical interventions from 7 to 32 on average, and, although there was a decrease in the number of standard orientation, the pharmaceutical orientation had an increase, causing a rise of pharmaceutical orientation rate from 4 to 11%. The processes developed and implemented at the program pharmacy sought to follow the good pharmacy practice, and help patients to make the best use of their medications.

Biofunctionality and immunocompatibility of starch-based biomaterials

Marques, Alexandra Margarida Pinto

A procura de novos biomateriais que desempenhem funcoes especificas sem, no entanto, desencadearem respostas negativas nos hospedeiros constitui um desafio permanente e actual nesta area. Biomateriais degradaveis foram uma das solucoes propostas e actualmente em aplicacao mas, embora possuam vantagens inegaveis, tambem apresentam alguns problemas nomeadamente no que diz respeito aos seus produtos de degradacao e respectivos efeitos negativos consequentes. Outros biomateriais, entre os quais polimeros de origem natural, foram propostos considerando que os seus produtos de degradacao poderao ser incorporados nas vias metabolicas normais evitando efeitos secundarios no hospedeiro. Ate ao momento, e apesar de todos os esforcos e do grande numero de dispositivos biomedicos desenvolvidos, o biomaterial ideal para uma aplicacao especifica ainda nao foi encontrado. Estudos com polimeros biodegradaveis a base de amido demonstraram que estes materiais possuem propriedades promissoras abrindo novas perspectivas para a sua possivel aplicacao numa variedade de aplicacoes biomedicas. Assim, de modo a demonstrar que estes materiais tem de facto potencial para serem utilizados em, por exemplo, substituicao ossea, sistemas de libertacao controlada, cimentos osseos e engenharia de tecidos, seria imperativo avaliar com maior profundidade a resposta biologica desencadeada pelos mesmos. Para tal foi delineado um plano de trabalhos com tres objectivos principais: i) avaliar a citocompatibilidade dos polimeros e compositos a base de amido com monitorizacao da citotoxicidade e analise da adesao e proliferacao celulares nas suas superficies. Foi dada particular atencao a osteoblastos considerando uma possivel aplicacao ortopedica para estes materiais; ii) estabelecer modelos in vitro para analisar e prever, tanto quanto possivel, uma situacao real de resposta inflamatoria; iii) validar os resultados in vitro com um modelo in vivo ja estabelecido em outros trabalhos de analise da resposta inflamatoria a biomateriais. Em resumo, os estudos de citocompatibilidade e imunocompatibilidade demonstraram que os polimeros e compositos a base de milho sao biomateriais promissores. Em comparacao com os biomateriais degradaveis actualmente em uso, possuem propriedades capazes de induzir um comportamento semelhante, ou mesmo melhor, em termos de citotoxicidade. Estes dados foram reconfirmados com a adesao e proliferacao de celulas do tipo osteoblastos na superficie de alguns dos materiais a base de amido, que demonstraram ser comparaveis as observadas no PLLA, evidenciando a possibilidade de usar esses materiais em aplicacoes ortopedicas. As conclusoes retiradas dos estudos in vitro e in vivo de imunocompatibilidade reforcam as observacoes das experiencias de citocompatibilidade e em conjunto, evidenciam a possibilidade de utilizacao dos biomateriais a base de amido, com fraca capacidade de desencadear uma reaccao inflamatoria, em aplicacoes biomedicas.

O presente trabalho, sobre a intervenção de metodologias de ensino, foi desenvolvido na Escola Estadual Colônia dos Pescadores, na cidade de Caraguatatuba - SP, em três turmas do terceiro ano do Ensino Médio, perfazendo um total de 119 educandos, entre 16 e 19 anos. Antes de iniciar-se a intervenção, um questionário de vinte perguntas objetivas e dissertativas foi desenvolvido, aplicado pelo professor da classe, que ministrou as aulas correspondentes. Este questionário foi o mesmo em todas as três classes com o objetivo de diagnosticar o conhecimento prévio dos alunos sobre Astronomia. Começando a intervenção nas turmas, o professor envolvido usou três diferentes metodologias de ensino: (A) em forma de seminários, elaborados e apresentados pelos alunos, nos quais o professor fazia apenas as intervenções necessárias, (B) na forma tradicional, com a ajuda de multimídia para o desenvolvimento das aulas e a terceira (C) a tradicional, fazendo uso exclusivo de lousa e giz. No final do trabalho os alunos responderam o mesmo questionário novamente, de modo que os três métodos utilizados puderam ser comparados. Os resultados apresentados após a intervenção foram melhores que os resultados iniciais indicando a ocorrência de uma aprendizagem significativa. Quando os estudantes foram inicialmente questionados sobre quantos planetas existem no nosso sistema solar, a classe A obteve 39% de respostas certas, a classe B 48% e a classe C 46%, mas após o desenvolvimento das atividades, as classes obtiveram respectivamente 94%, 97 % e 90% de aproveitamento. No término do bimestre, foi sugerido aos educandos que elaborassem uma história em quadrinhos, a qual serviu para averiguar se os conceitos inicialmente observados foram alterados e se novos foram agregados. A análise das histórias foi dividida em três partes: Criatividade; Temas abordados; Emprego correto dos conceitos estudados. Ao final quatorze histórias foram confeccionadas. O aprendizado foi tão significativo que os alunos produzira m histórias em quadrinhos, com informações muito ricas. Outro dado muito importante é que, apesar da Astronomia ser um tema amplamente recomendado, não é ensinado nem em escolas de ensino fundamental nem no ensino médio.

The VIII Municipality of Rome is characterized by a high poverty rate, by the presence of many immigrant communities and by the lack of health services available to vulnerable social groups. In 2005 , the " Servizio di Medicina Solidale" of the University Hospital of "Tor Vergata", for the first time intervened in this Municipality regarding Immigrant Health. The paper describes the activities and organization of this service from January 2005 to December 2007. It demonstrates a complex epidemiological picture of 2,374 immigrants, characterized by a young population, mostly women with reproductive health issues, followed by children with infectious and nutritional problems and, ultimately, adults who accessed the service, firstly for gastroenterological problems, secondly for cardiovascular problems and finally for dysmetabolic disorders. The paper describes the culture-centered actions of Health Promotion and Health Education in order to improve health awareness and promote integration of immigrants. The study indicates that the limited number of hospital admissions ( n.20) with respect to the number of outpatient visits (n.70.000) in the first seven years of the service " Medicina Solidale" has significantly reduced the number of unnecessary admissions to emergency wards. In conclusion it is notable that the cost of such intervention results eight times inferior to emergency admissions and further confirms that a Community medicine approach is sustainable.

Malaria was one of the most important public health problems of the Colonial Medicine and, for this reason, the subject was reflected in the Spanish medical journalism. The aim of the paper was to reconstruct the Spanish contributions to international health during the first half of the twentieth century. The primary sources of information on malaria were the medical journals Medicina de los Países Cálidos and Medicina Colonial, between 1929 and 1954. The documents were classified according to the sections of the magazine and its contents were studied, framing them in the history of international public health. In primary sources were found 466 documents. Malaria was one of the major diseases of the Spanish Protectorate in Morocco and Spanish Guinea, favoured by the occupation of the Spanish army. Antimalaria campaigns included strategies such as the use of Dichloro-diphenyl-trichloroethane, preventive education and massive quininización. Malariology in the specialized journalism, experienced a growing boom. The most outstanding authors in magazines analyzed were Gustavo Pittaluga, Sadí de Buen, Eliseo de Buen and Juan Gil-Collado. The Spanish specialized journalism provides the importance e interaction in antimalaria campaigns in Spain and Spanish African colonies of scientific, professional, political and military factors. The colonial situation was negative and marked differences between metropolis and colonies in terms of the effort, efficiency and the different temporal sequence of the measures undertaken.

Separating Mass and Height Contributions in Gravity Variations at Medicina, Italy

Zerbini, S.; Bruni, S.; Errico, M.; Santi, E.; Wziontek, H.

2016-12-01

During 1996, at the Medicina station, a GPS and a superconducting gravimeter (SG) were installed in the framework of an experiment focused on the comparison between height and gravity variations. Absolute gravity observations are also performed twice a year and environmental parameters, among others water table levels, are recorded continuously. The station is also equipped with a second GPS system, the two antennas are very close to each other, and both are located in close proximity to the VLBI dish. Two decades of continuous height and gravity observations are now available which allow investigating both long and short period signals and the relevant correlations between the two measured quantities. Long period signatures are observed, a principal component is due to subsidence which is well known to occur in the area; however, also non-linear long-period behaviors are observed. Seasonal effects are also clearly recognizable in the time series and are mainly associated with the water table seasonal behavior. The station is characterized by clayey soil which is subject to consolidation effects when the water table lowers during the summer period. This effect is particularly recognizable in the SG data since the instrument is installed on a shallow foundation pillar which may suffer for height decreases in the order of 2,5-3 cm for water table lowering of 2 m.

Crustal Movements and Gravity Variations in the Southeastern Po Plain, Italy

At the Medicina observatory, in the southeastern Po Plain, in Italy, we have started a project of continuous GPS and gravity observations in mid 1996. The experiment, focused on a comparison between height and gravity variations, is still ongoing; these uninterrupted time series certainly constitute a most important data base to observe and estimate reliably long-period behaviors but also to derive deeper insights on the nature of the crustal deformation. Almost two decades of continuous GPS observations from two closely located receivers have shown that the coordinate time series are characterized by linear and non-linear variations as well as by sudden jumps. Both over long- and short-period time scales, the GPS height series show signals induced by different phenomena, for example, those related to mass transport in the Earth system. Seasonal effects are clearly recognizable and are mainly associated with the water table seasonal behavior. To understand and separate the contribution of different forcings is not an easy task; to this end, the information provided by the superconducting gravimeter observations and also by absolute gravity measurements offers a most important means to detect and understand mass contributions. In addition to GPS and gravity data, at Medicina, a number of environmental parameters time series are also regularly acquired, among them water table levels. We present the results of study investigating correlations between height, gravity and environmental parameters time series.

Stress among healthcare students--a cross disciplinary perspective.

Jacob, Tamar; Itzchak, Esther Ben; Raz, Olga

2013-07-01

Perceived stress (PS) among healthcare students worldwide is a recognized problem. To address the paucity of data about the actual degree of PS, this study aimed to: 1) evaluate and compare PS across three healthcare programs (Physical Therapy [PT], Communication Disorders [CD], and Nutrition Sciences [NS]) in one university; 2) evaluate changes in PS across study years; 3) identify the contribution of academic- and socio-demographic-related variables to PS; and 4) determine whether the Israeli students' PS levels differ from those of their peers in other countries. A cross-sectional survey was performed among all undergraduate PT, CD, and NS students from one university. Data were collected using anonymous questionnaires. Instruments included the Perceived Stress Scale 10 (PSS) and the Undergraduate Sources of Stress (USOS). ANOVA was used to evaluate the differences between the three programs, and regression analysis to evaluate the contribution of socio-demographic factors to PS and USOS. A total of 312 students (PT--154; CD--92; NS--66) participated in the study. Mean PSS (range: 13.5-13.6) was similar in the three programs. The USOS academic factor was the most reported source of stress in all programs. Most socio-demographic variables were not related to either PS or USOS. Students from PT, CD, and NS programs perceived similar levels of stress. The academic factor was perceived as the most important source of stress by students from the three departments, despite differences in the academic educational programs. Further studies are needed to generalize these results and enable a comparison between healthcare students and other students' stress perceptions.

The International Space Station (ISS) currently provides human waste collection and hygiene facilities in the Russian Segment Service Module (SM) which supports a three person crew. Additional hardware is planned for the United States Operational Segment (USOS) to support expansion of the crew to six person capability. The additional hardware will be integrated in an ISS standard equipment rack structure that was planned to be installed in the Node 3 element; however, the ISS Program Office recently directed implementation of the rack, or Waste and Hygiene Compartment (WHC), into the U.S. Laboratory element to provide early operational capability. In this configuration, preserved urine from the WHC waste collection system can be processed by the Urine Processor Assembly (UPA) in either the U.S. Lab or Node 3 to recover water for crew consumption or oxygen production. The human waste collection hardware is derived from the Service Module system and is provided by RSC-Energia. This paper describes the concepts, design, and integration of the WHC waste collection hardware into the USOS including integration with U.S. Lab and Node 3 systems.

2008-01-01

The International Space Station (ISS) United States Operational Segment (USOS) currently provides a Temporary Sleep Station (TeSS) as crew quarters for one crewmember in the Laboratory Module. The Russian Segment provides permanent crew quarters (Kayutas) for two crewmembers in the Service Module. The TeSS provides limited electrical, communication, and ventilation functionality. A new permanent rack sized USOS ISS Crew Quarters (CQ) is being developed. Up to four CQs can be installed into the Node 2 element to increase the ISS crewmember size to six. The new CQs will provide private crewmember space with enhanced acoustic noise mitigation, integrated radiation reduction material, controllable airflow, communication equipment, redundant electrical systems, and redundant caution and warning systems. The rack sized CQ is a system with multiple crewmember restraints, adjustable lighting, controllable ventilation, and interfaces that allow each crewmember to personalize their CQ workspace. Providing an acoustically quiet and visually isolated environment, while ensuring crewmember safety, is critical for obtaining crewmember rest and comfort to enable long term crewmember performance. The numerous human factor, engineering, and program considerations during the concept, design, and prototyping are outlined in the paper.

RESUMO Objetivo: Estudar o uso da biomembrana de látex e o transplante conjuntival autólogo na cicatrização conjuntival em coelhos. Métodos: Em nove coelhos albinos, neo-zelandeses, machos foram removidas áreas retangulares idênticas, do quadrante supero nasal, adjacente ao limbo, de ambos os olhos. As áreas desnudas da camada esclerótica nos olhos direitos foram recobertas com biomembrana de látex e a dos olhos esquerdos com enxerto conjuntival autólogo. Os animais foram sacrificados em grupos de três, aos 7, 14 e 21 dias após a cirurgia. Os tecidos do local cirúrgico, incluindo a córnea, foram fixados em formaldeído, antes de serem processados em parafina e corados com hematoxilina e eosina. A natureza e a intensidade da resposta inflamatória e o padrão de epitelização da superfície conjuntival foram avaliados sob microscopia óptica, em seções histológicas longitudinais, passando pelo centro dos espécimes anatômicos. Resultados: Até o décimo quarto dia pós-operatório, o grupo que recebeu a biomembrana apresentou reação inflamatória mais intensa do que o grupo com auto enxerto conjuntival. Aos 14 dias, os olhos com biomembrana apresentavam-se menos inflamados e com estroma mais espesso do que aos 7 dias. Aos 21 dias, a reparação conjuntival de ambos os grupos apresentavam características semelhantes. Conclusão: Apesar de apresentar uma cicatrização mais lenta, a biomembrana de látex se mostrou tão eficaz quanto o auto enxerto conjuntival na reconstrução da superfície ocular após três semanas de cicatrização pós-operatória. Devido as suas baixas toxicidade e alergenicidade, este material parece ser uma opção terapêutica promissora na reconstrução da conjuntiva.ABSTRACT Purpose: To study a latex biomembrane and conjunctival autograft with regard to the promotion of conjunctival healing in rabbits. The study included nine male albino rabbits. In these rabbits, a rectangular area of the conjunctiva was surgically removed from the superonasal quadrant adjacent to the limbus in both eyes. The bare area of the sclerotic coat of the right eye was reconstructed with a latex biomembrane, and the corresponding site of the left eye was reconstructed with a conjunctival autograft. The animals were killed in groups of three at 7, 14, and 21 days after surgery. The tissues from the surgical site, including the cornea, were fixed in formaldehyde, and were then processed in paraffin and stained with hematoxylin and eosin. The nature and intensity of the inflammatory response and the epithelial pattern at the conjunctival surface were evaluated under optical microscopy with longitudinal histological sections through the center of the anatomical specimens. Until the 14th postoperative day, the inflammatory reaction was greater in the biomembrane group than in the conjunctival autograft group. In the latex biomembrane group, inflammation was less intense and the stroma was thicker on the 14th postoperative day than on the 7th postoperative day. After three weeks, conjunctival healing in both groups showed similar characteristics. Although healing was slower with a latex biomembrane, tissue reconstitution was almost the same as that with a conjunctival autograft by three weeks. A latex biomembrane is as effective as a conjunctival autograft for the reconstruction of the ocular surface. Owing to the lack of toxicity and allergenicity, a latex biomembrane appears to be a promising therapeutic option for conjunctival reconstruction.

Temperature, radiation and aging analysis of the DORIS Ultra Stable Oscillator by means of the Time Transfer by Laser Link experiment on Jason-2

The Time Transfer by Laser Link (T2L2) experiment on-board the Jason-2 satellite was launched in June 2008 at 1335 km altitude. It has been designed to use the Satellite Laser Ranging (SLR) space technique as an optical link between ground and space clocks. T2L2, as all the instruments aboard Jason-2, is referenced to the Ultra Stable Oscillator (USO) provided by the Doppler Orbitography and Radio-positioning Integrated by Satellite (DORIS) system. A complex data processing has been developed in order to extract time & frequency products as the relative frequency bias of the USO from ground-to-space time transfer passages. The precision of these products was estimated of a few parts in 10-13 given the very good in-flight performance of T2L2 with a ground-to-space time stability of a few picoseconds (ps) over 100 s. Frequency bias from T2L2 were compared with results from operational orbit computation, notably with the DIODE (Détermination Immédiate d'Orbite par Doris Embarqué) outputs (see Jayles et al. (2016) same issue) at the level of 1 · 10-12. The present paper is focusing on the main physical effects which drive the frequency variations of the Jason-2 USO during its flight, notably over the South Atlantic Anomaly (SAA) area. In addition to the effects of radiation we studied the effect of the residual temperature variations, in the range 8-11 °C (measured on-board). A model was established to represent these effects on the short term with empirical coefficients (sensitivities of the USO) to be adjusted. The results of fitting the model over ∼200 10-day periods, from 2008 to 2014, show the sensitivities of the Jason-2 USO to temperature and radiation. The analysis of the 6-year output series of empirical coefficients allows us to conclude that: (i) the temperature to frequency dependence is very stable along time at the level of around -1.2 · 10-12 per °C, (ii) the radiation effects are much lower than those previously detected on the Jason-1 USO with a factor > 10. The swept material used by manufacturers for the Jason-2 quartz oscillator has such properties to avoid non-linear effects >1-2 · 10-12, (iii) the model is available at 1 min or less over the Jason-2 mission, with a level of consistency of 5 · 10-13, which is the average RMS of the post-fit residuals.

There are some mechanism to commercialize the innovations that have been developed by academic scientists in universities, i.e. patenting, licensing, start-up creation, and university-industry partnerships. The start-up creations or university spin-offs (USOs) company is a very special start-up company that is founded by an academic inventor and the university with the aim to commercialize the technological innovation that created by the university. However, it is not always as smooth as expected. The market competitiveness of the USOs obviously has many challenges to be able to compete with the existing companies, analysis need to be done to get the right business step so the business strategy will be efficient. In this article, we discuss a real case study of a university spin-off that owned by Sebelas Maret University for Commercializing Battery Lithium. The aim of our research is twofold: first, to identify the gap in the literature of business strategy formulation between a conventional and USOs. Second, to propose a business strategy formulation for commercializing university-created technology, i.e. battery lithium as core business of a university spin-off as a case study. We conduct surveys, observation and FGD in order to collect the data and information to build the company objective and goals. The analytical tools to generate the solution of business strategy are SWOT analysis, IFE-EFE matrix, and QSPM model so the result will be the most attractive and suitable for the company. The result shows that the case study of USO company is classified on conservative continuous improvement phase so the suitable strategy for this company are product development and business strategy integration.

Edible plants with underground storage organs (USOs) are neglected resources. We studied the local ecological knowledge edible plants with (USOs) in rural populations of North-Patagonia in order to establish how people are utilizing these plants. Some aspect of corpus-praxis-cosmos complex associated to the local ecological knowledge was documented and discussed. In addition, variation in this ecological knowledge due to age, gender, family structure, ethnic self-determination was also evaluated. Semi-structured interviews were conducted with 51 inhabitants in order to study the relationship between the current use of plants with USOs and the age, sex, family group composition and ethnic self-identification of interviewees. In addition, the Cultural Importance Index for each species was calculated. The current richness of known species in these populations is a total of 9 plants. Plants with USOs tend to be used more frequently as the age of the interviewee increases. Women and men showed no differences in the average richness of species cited. The interviewees who share their homes with other generations use these plants more frequently than those who live alone. Our results indicate that the interviewees who identified themselves as belonging to the Mapuche people use these plants more frequently. For the Mapuche people, wild plants have constituted material and symbolic resources of great importance in their historical subsistence. In addition, they are currently being redefined as elements which present a connection with ancestral practices, produce a strong relationship with the 'land', and become markers which identify the 'natural' (historical) ways of their people; these are key elements in the current political processes of identity revaluation. This research is valuable to stimulate cultural revival and health promotion programs in the communities with their own local, cultural food.

The anorectal anomalies consist in a complex group of birth defects. Laparoscopic-assisted anorectoplasty improved visualization of the rectal fistula and the ability to place the pull-through segment within the elevator muscle complex with minimal dissection. There is no consensus on how the fistula should be managed. To evaluate the laparoscopic-assisted anorectoplasty and the treatment of the rectal urinary fistula by a bipolar sealing device. It was performed according to the original description by Georgeson1. Was used 10 mm infraumbilical access portal for 30º optics. The pneumoperitoneum was established with pressure 8-10 cm H2O. Two additional trocars of 5 mm were placed on the right and left of the umbilicus. The dissection started on peritoneal reflection using Ligasure(r). With the reduction in the diameter of the distal rectum was identified the fistula to the urinary tract. The location of the new anus was defined by the location of the external anal sphincter muscle complex, using electro muscle stimulator externally. Finally, it was made an anastomosis between the rectum and the new location of the anus. A Foley urethral probe was left for seven days. Seven males were operated, six with rectoprostatic and one with rectovesical fistula. The follow-up period ranged from one to four years. The last two patients operated underwent bipolar sealing of the fistula between the rectum and urethra without sutures or surgical ligation. No evidence of urethral leaks was identified. There are benefits of the laparoscopic-assisted anorectoplasty for the treatment of anorectal anomaly. The use of a bipolar energy source that seals the rectal urinary fistula has provided a significant decrease in the operating time and made the procedure be more elegant. As anomalias anorretais consistem de um grupo complexo de defeitos congênitos. A anorretoplastia laparoscópica permite melhor visualização da fístula retourinária e propicia o posicionamento do reto abaixado dentro do complexo muscular do elevador do ânus com mínima dissecção. Não há consenso na literatura sobre o melhor tratamento dessa fístula. Avaliar a anorretoplastia laparoscópica e o selamento bipolar da fístula retourinária. Ela foi realizada de acordo com a descrição original de Georgeson1. Utilizou-se o acesso infraumbilical com portal de 10 mm para a ótica de 30º. O pneumoperitônio foi estabelecido com pressão de 8-10 cm de H2O. Dois trocárteres adicionais de 5 mm foram colocados à direita e à esquerda da cicatriz umbilical. A dissecção foi iniciada na reflexão peritoneal usando Ligasure(r). Com a redução do calibre do reto distalmente, foi identificada a fístula para a o trato urinário. O local do novo ânus foi definido por meio da localização do complexo muscular do esfíncter anal externo, utilizando-se estimulador eletro muscular externamente. Por fim, foi confeccionada uma anastomose entre o reto e o novo local do ânus. Uma sonda uretral de Foley foi deixada durante sete dias. Sete meninos foram operados, seis com fístula retoprostática e um retovesical. O período de seguimento variou de um a quatro anos. Os dois últimos pacientes operados foram submetidos ao selamento bipolar da fístula entre o reto e a uretra, sem suturas ou ligadura cirúrgica com pontos. No seguimento em longo prazo não houve evidências de fístulas urinárias. Há benefícios da anorretoplastia laparoscópica para o tratamento de anomalia anorretal. O uso de uma fonte de energia bipolar que promova o selamento da fístula retourinária propiciou redução significativa do tempo cirúrgico e tornou o procedimento mais elegante.

The Magnetospheric Multiscale (MMS) mission consists of four satellites flying in formation in highly elliptical orbits about the Earth, with a primary objective of studying magnetic reconnection. The baseline navigation concept is independent estimation of each spacecraft state using GPS pseudorange measurements referenced to an Ultra Stable Oscillator (USO) with accelerometer measurements included during maneuvers. MMS state estimation is performed onboard each spacecraft using the Goddard Enhanced Onboard Navigation System (GEONS), which is embedded in the Navigator GPS receiver. This paper describes the sensitivity of MMS navigation performance to two major error sources: USO clock errors and thrust acceleration knowledge errors.

RESUMEN El objetivo de este estudio fue analizar el uso de la punción lumbar (PL) en las sospechas de sepsis neonatal tardía. Se recomienda realizar una PL en la evaluación de toda sospecha de sepsis neonatal tardía. Se utilizó una cohorte de 414 neonatos con peso al nacer <2000g en tres hospitales de Lima. Se realizó la PL en 45/214 (21,0%) sospechas de sepsis y en 13/48 (27,1%) sepsis confirmadas por hemocultivo. Se diagnosticó meningitis en 8/214 (3,7%) sospechas y en 8/45 (17,5%) episodios en los que se realizó la PL. El tiempo de tratamiento de los episodios sin PL fue similar a los episodios de sepsis con meningitis descartada y menor a los episodios de meningitis. El uso de la PL es bajo, lo que puede resultar en meningitis no diagnosticadas y tratadas inadecuadamente. Es necesario reforzar la importancia de la PL en la evaluación de sepsis neonatal.

The effectiveness of a motivational and skills training HIV/AIDS group intervention designed for men in substance abuse treatment was evaluated. Men in methadone maintenance (n=288) or outpatient psychosocial treatment (n=302) completed assessments at baseline, 2 weeks, 3- and 6-months post intervention. Participants were randomly assigned to attend either “Real Men Are Safe” (REMAS; five sessions containing information, motivational exercises and skills training), or HIV education (HIV-Ed; one session containing HIV prevention information). REMAS participants engaged in significantly fewer unprotected vaginal and anal sexual intercourse occasions (USO) during the 90 days prior to the 3- and 6-month follow-ups than HIV-Ed participants. Completing REMAS resulted in an even stronger effect: completers reduced their number of USO by 21% from baseline to 6-month follow-up. In contrast, HIV-Ed completers increased the number of USO by 2%. A motivational and skills training HIV prevention intervention designed for men was associated with greater sexual risk reduction over standard HIV education. Substance abuse treatment programs can therefore help reduce sexual risk among their clientele by providing a more intensive intervention than what is traditionally provided. PMID:19150206

To describe the characteristics of advertising in Spanish medical journals and to analyze the advertising message in drug advertisements. Six issues of 4 Spanish medical journals published in 2001 were reviewed to identify the number of advertisements and their characteristics. The journals selected were Atención Primaria, Anales Españoles de Pediatría, Medicina Clínica and Gaceta Sanitaria. The advertising message was analyzed by evaluating 5 factors: communication aim, sales argument, communication treatment, and use of text and image. 609 advertisements were found. Drug advertisements were the most numerous (69.9%). Advertising pressure was highest in Atención Primaria (36%), followed by Anales Españoles de Pediatría (22%), Medicina Clínica (12%) and Gaceta Sanitaria (4%). Of the 195 drug advertisements analyzed, the aim of the advertising message was mostly to present or remind readers of an existing product (70.8%). The sales argument was rational in 86.5%. The communication treatment was advertising in 72.6%. The text of the advertisement contained a headline in 82.4% or a slogan in 50.8%. The advertisement image was a photograph in 74.7% and the aim of the image was to present the product (48.7%), to promise a benefit (45.1%), or to argue its qualities (31.1%). In the journals aimed at prescribing physicians advertising pressure was higher and advertisements were intercalated in article text. Advertising concerned already existing products, used rational arguments, and the communication treatment was advertising.

One of the most challenging aspects of the new-generation Low-Frequency Aperture Array (LFAA) radio telescopes is instrument calibration. The operational LOw-Frequency ARray (LOFAR) instrument and the future LFAA element of the Square Kilometre Array (SKA) require advanced calibration techniques to reach the expected outstanding performance. In this framework, a small array, called Medicina Array Demonstrator (MAD), has been designed and installed in Italy to provide a test bench for antenna characterization and calibration techniques based on a flying artificial test source. A radio-frequency tone is transmitted through a dipole antenna mounted on a micro Unmanned Aerial Vehicle (UAV) (hexacopter) and received by each element of the array. A modern digital FPGA-based back-end is responsible for both data-acquisition and data-reduction. A simple amplitude and phase equalization algorithm is exploited for array calibration owing to the high stability and accuracy of the developed artificial test source. Both the measured embedded element patterns and calibrated array patterns are found to be in good agreement with the simulated data. The successful measurement campaign has demonstrated that a UAV-mounted test source provides a means to accurately validate and calibrate the full-polarized response of an antenna/array in operating conditions, including consequently effects like mutual coupling between the array elements and contribution of the environment to the antenna patterns. A similar system can therefore find a future application in the SKA-LFAA context.

OBJECTIVES: This study sought to verify the effects of acupuncture as an adjuvant treatment for the control of asthma. METHODS: This was a randomized, controlled, crossover trial conducted at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A total of 74 patients with mild/moderate, persistent asthma were randomized into two therapeutic groups: Group A – 31 patients underwent 10 real weekly acupuncture sessions, followed by a 3-week washout period and 10 sham weekly acupuncture sessions; and Group B - 43 patients underwent 10 sham weekly acupuncture sessions, followed by a 3-week washout period and 10 real weekly acupuncture sessions. Patients used short- and long-acting β-2 agonists and inhaled corticosteroids when necessary. Prior to treatment and after each period of 10 treatment sessions, the patients were evaluated for spirometry, induced sputum cell count, exhaled nitric oxide (NO) and with the Short Form 36 (SF-36) and Questionnaire on Quality of Life-Asthma (QQLA) questionnaires. Daily peak flow and symptom diaries were registered. The level of significance adopted was 5% (α=0.05). RESULTS: In Group B, after real acupuncture, there was a decrease in eosinophils (p=0.035) and neutrophils (p=0.047), an increase in macrophages (p=0.001) and an improvement in peak flow (p=0.01). After sham acupuncture treatment, patients experienced less coughing (p=0.037), wheezing (p=0.013) and dyspnea (p=0.014); similarly, after real acupuncture, patients reported less coughing (p=0.040), wheezing (p=0.012), dyspnea (p<0.001) and nocturnal awakening episodes (p=0.009). In Group A, there was less use of rescue medication (p=0.043). After the sham procedure, patients in Group A experienced less coughing (p=0.007), wheezing (p=0.037), dyspnea (p<0.001) and use of rescue medication (p<0.001) and after real acupuncture, these patients showed improvements in functional capacity (p=0.004), physical aspects (p=0.002), general health status (p<0.001) and vitality (p=0.019). Sham acupuncture also led to significant differences in symptoms, but these were not different from those seen with real acupuncture. Spirometry and exhaled NO levels did not show a difference between sham and real acupuncture treatment. In addition, no significant difference was demonstrated between treatments regarding the quality of life evaluation. CONCLUSION: Real and sham acupuncture have different effects and outcomes on asthma control. The crossover approach was not effective in this study because both interventions led to improvement of asthma symptoms, quality of life and inflammatory cell counts. Thus, sham acupuncture cannot serve as a placebo in trials with acupuncture as the main intervention for asthma. PMID:26598077

The objective of the current study was to examine predictors and moderators of response to two HIV sexual risk interventions of different content and duration for individuals in substance abuse treatment programs. Participants were recruited from community drug treatment programs participating in the National Institute on Drug Abuse Clinical Trials Network (CTN). Data were pooled from two parallel randomized controlled CTN studies (one with men and one with women) each examining the impact of a multi-session motivational and skills training program, in comparison to a single-session HIV education intervention, on the degree of reduction in unprotected sex from baseline to 3- and 6- month follow-ups. The findings were analyzed using a zero-inflated negative binomial (ZINB) model. Severity of drug use (p < .01), gender (p < .001), and age (p < .001) were significant main effect predictors of number of unprotected sexual occasions (USOs) at follow-up in the non-zero portion of the ZINB model (men, younger participants, and those with greater severity of drug/alcohol abuse have more USOs). Monogamous relationship status (p < .001) and race/ethnicity (p < .001) were significant predictors of having at least one USO vs. none (monogamous individuals and African Americans were more likely to have at least one USO). Significant moderators of intervention effectiveness included recent sex under the influence of drugs/alcohol (p < .01 in non-zero portion of model), duration of abuse of primary drug (p < .05 in non-zero portion of model), and Hispanic ethnicity (p < .01 in the zero portion, p < .05 in the non-zero portion of model). These predictor and moderator findings point to ways in which patients may be selected for the different HIV sexual risk reduction interventions and suggest potential avenues for further development of the interventions for increasing their effectiveness within certain subgroups.

The ability to control the temperature and humidity of an environment or habitat is critical for human survival. These factors are important to maintaining human health and comfort, as well as maintaining mechanical and electrical equipment in good working order to support the human and to accomplish mission objectives. The temperature and humidity of the International Space Station (ISS) United States On-orbit Segment (USOS) cabin air is controlled by the Common Cabin Air Assembly (CCAA). The CCAA consists of a fan, a condensing heat exchanger (CHX), an air/water separator, temperature and liquid sensors, and electrical controlling hardware and software. The CHX is the primary component responsible for control of temperature and humidity. The CCAA CHX contains a chemical coating that was developed to be hydrophilic and thus attract water from the humid influent air. This attraction forms the basis for water removal and therefore cabin humidity control. However, there have been several instances of CHX coatings becoming hydrophobic and repelling water. When this behavior is observed in an operational CHX in the ISS segments, the unit s ability to remove moisture from the air is compromised and the result is liquid water carryover into downstream ducting and systems. This water carryover can have detrimental effects on the ISS cabin atmosphere quality and on the health of downstream hardware. If the water carryover is severe and widespread, this behavior can result in an inability to maintain humidity levels in the USOS. This paper will describe the operation of the five CCAAs within the USOS, the potential causes of the hydrophobic condition, and the impacts of the resulting water carryover to downstream systems. It will describe the history of this behavior and the actual observed impacts to the ISS USOS.

The ability to control the temperature and humidity of an environment or habitat is critical for human survival. These factors are important to maintaining human health and comfort, as well as maintaining mechanical and electrical equipment in good working order to support the human and to accomplish mission objectives. The temperature and humidity of the International Space Station (ISS) United States On-orbit Segment (USOS) cabin air is controlled by the Common Cabin Air Assembly (CCAA). The CCAA consists of a fan, a condensing heat exchanger (CHX), an air/water separator, temperature and liquid sensors, and electrical controlling hardware and software. The CHX is the primary component responsible for control of temperature and humidity. The CCAA CHX contains a chemical coating that was developed to be hydrophilic and thus attract water from the humid influent air. This attraction forms the basis for water removal and therefore cabin humidity control. However, there have been several instances of CHX coatings becoming hydrophobic and repelling water. When this behavior is observed in an operational CHX, the unit s ability to remove moisture from the air is compromised and the result is liquid water carryover into downstream ducting and systems. This water carryover can have detrimental effects on the cabin atmosphere quality and on the health of downstream hardware. If the water carryover is severe and widespread, this behavior can result in an inability to maintain humidity levels in the USOS. This paper will describe the operation of the five CCAAs within in the USOS, the potential causes of the hydrophobic condition, and the impacts of the resulting water carryover to downstream systems. It will describe the history of this behavior and the actual observed impacts to the ISS USOS. Information on mitigation steps to protect the health of future CHX hydrophilic coatings and potential remediation techniques will also be discussed.

This review aims to develop a critical and current analysis of the basic structure of a Postgraduate program for proposing improvement actions and new evaluation criteria. To examine the items that are areas of concentration (AC), research lines (LP), research projects (PP), curricular structure and fundraising were consulted the Area Document, the 2013 Evaluation Report and the Assessment Sheets of Medicine III programs, evaluated in the 2010-2012 period. Consistency is recommended especially among AC, LP and PP, with genuine link between activities and permanent teachers skills and based on structured curriculum in the education of the student. The Program Proposal interfere, and much, in qualifying a program. The curriculum should provide subsidy to the formation of the researcher, through the core subjects, and development of PP, being the concept of disciplines to support lines and research projects. Fundraise should be set out in research projects and in the CV-Lattes. The area recommended that at least 40-50% of permanent teachers present fundraising and the minimum 20-25% of these teachers to have productivity scholarship PQ / CNPq during the triennium. It is necessary to promote wide discussion and find a consensus denominator for these issues. The actions should contribute to the improvement of evaluation forms and certainly for the qualification of the programs but graduate. Essa revisão tem como objetivo elaborar uma análise crítica e atual da estrutura básica de um programa de Pós-Graduação para a proposição de ações de aperfeiçoamento e novos critérios de avaliação. Para analisarem-se os itens áreas de concentração (AC), linhas de pesquisa (LP), projetos de pesquisa (PP), estrutura curricular e captação de recursos/fomentos foram consultados o documento de área, o relatório de avaliação 2013 e as fichas de avaliação dos programas da Medicina III, avaliados no triênio 2010-2012. A coerência é recomendada especialmente entre AC, LP e PP, com substancial vínculo entre atividades e competências do corpo de docentes permanentes e embasamento da grade curricular na formação do aluno. A Proposta do Programa interfere, e muito, na qualificação de um programa. A estrutura curricular deverá dar subsídio à formação do pesquisador, por meio das disciplinas nucleares, e ao desenvolvimento dos PP, de competência das disciplinas de apoio às linhas e aos projetos de pesquisa. Os fomentos devem ser indicados nos projetos de pesquisa e no CV-Lattes dos beneficiados/responsáveis pelos projetos. A área recomenda que, no mínimo, 40 a 50% dos docentes permanentes apresentem captação de recursos e que o mínimo de 20 a 25% desses docentes tenham bolsa de produtividade PQ/CNPq durante o triênio. Há que se promover ampla discussão e encontrar um denominador de consenso para essas questões. As ações deverão contribuir para o aprimoramento das fichas de avaliação e, certamente, para a qualificação dos programas de pós-graduação.

Treatment refusal and abandonment are major causes of treatment failure for children with cancer in low- and middle-income countries (LMICs), like Guatemala. This study identified risk factors for and described the intervention that decreased abandonment. This was a retrospective study of Guatemalan children (0-18 years) with cancer treated at the Unidad Nacional de Oncología Pediátrica (UNOP), 2001-2008, using the Pediatric Oncology Network Database. Treatment refusal was a failure to begin treatment and treatment abandonment was a lapse of 4 weeks or longer in treatment. The impact of medicina integral, a multidisciplinary psychosocial intervention team at UNOP was evaluated. Cox proportional hazards analysis identified the effect of demographic and clinical factors on abandonment. Kaplan-Meier analysis estimated the survival. Of 1,789 patients, 21% refused or abandoned treatment. Abandonment decreased from 27% in 2001 to 7% in 2008 following the implementation of medicina integral. Factors associated with increased risk of refusal and abandonment: greater distance to the centre (P < 0.001), younger age (P = 0.017) and earlier year of diagnosis (P < 0.001). Indigenous race/ethnicity (P = 0.002) was associated with increased risk of abandonment alone. Abandonment correlated with decreased overall survival: 0.57 ± 0.02 (survival ± standard error) for those who completed therapy versus 0.06 ± 0.02 for those who abandoned treatment (P < 0.001) at 8.3 years. This study identified distance, age, year of diagnosis and indigenous race/ethnicity as risk factors for abandonment. A multidisciplinary intervention reduced abandonment and can be replicated in other LMICs. © 2017 Wiley Periodicals, Inc.

The source of research funding can result in bias, and its disclosure is essential in the publication of results. The aim of the study is to identify the frequency and type of sources of funding in the articles published by four Spanish biomedical journals published in Spanish. The frequency and type of financial disclosures in the articles published during 2012 in the ordinary numbers of Atención Primaria, Medicina Clínica, Revista Clínica Española and Revista Española de Cardiología were analyzed. Articles described as "Editorial", "Original article", "Consensus Document", "Review" and "Special Article" were considered. It was decided in each case whether or not the article included any funding disclosure and the type of the declared funding (public or private). Four hundred and twelve publications were analyzed. In 32.5% there was disclosure of funding: 38% in Atención Primaria, 27% in Medicina Clínica, 15% in Revista Clínica Española and 45% in Revista Española de Cardiología. By type of articles, 47% of original articles, 44% of consensus documents, 21% of reviews, 14% of special articles and 8% of editorials had a funding source. In 51.5% of the cases, funding was exclusively public, in 36.5% exclusively private and in 10% mixed. There is considerable variability in the disclosure of funding sources in articles appearing in these four Spanish biomedical journals. It would be necessary to improve the disclosure requirements of sources of funding, making them uniform, clear and transparent.

Background: Soccer is the most popular sport in Brazil and a high incidence of related trauma is reported. Maxillofacial trauma can be quite common, sometimes requiring prolonged hospitalization and invasive procedures. To characterize soccer-related facial fractures needing surgery in 2 major Brazilian Centers. Methods: A retrospective review of trauma medical records from the Plastic Surgery Divisions at the Universidade Federal de São Paulo–Escola Paulista de Medicina and the Hospital das Clinicas–Universidade de São Paulo was carried out to identify patients who underwent invasive surgical procedures due to acute soccer-related facial fractures. Data points reviewed included gender, date of injury, type of fracture, date of surgery, and procedure performed. Results: A total of 45 patients (31 from Escola Paulista de Medicina and 14 from Universidade de São Paulo) underwent surgical procedures to address facial fractures between March 2000 and September 2013. Forty-four patients were men, and mean age was 28 years. The fracture patterns seen were nasal bones (16 patients, 35%), orbitozygomatic (16 patients, 35%), mandibular (7 patients, 16%), orbital (6 patients, 13%), frontal (1 patient, 2%), and naso-orbito-ethmoid (1 patient, 2%). Mechanisms of injury included collisions with another player (n = 39) and being struck by the ball (n = 6). Conclusions: Although it is less common than orthopedic injuries, soccer players do sustain maxillofacial trauma. Knowledge of its frequency is important to first responders, nurses, and physicians who have initial contact with patients. Missed diagnosis or delayed treatment can lead to facial deformities and functional problems in the physiological actions of breathing, vision, and chewing. PMID:25289361

In 2016 September, the microquasar Cygnus X-3 underwent a giant radio flare, which was monitored for 6 d with the Medicina Radio Astronomical Station and the Sardinia Radio Telescope. Long observations were performed in order to follow the evolution of the flare on an hourly scale, covering six frequency ranges from 1.5 to 25.6 GHz. The radio emission reached a maximum of 13.2 ± 0.7 Jy at 7.2 GHz and 10 ± 1 Jy at 18.6 GHz. Rapid flux variations were observed at high radio frequencies at the peak of the flare, together with rapid evolution of the spectral index: α steepened from 0.3 to 0.6 (with Sν ∝ ν-α) within 5 h. This is the first time that such fast variations are observed, giving support to the evolution from optically thick to optically thin plasmons in expansion moving outward from the core. Based on the Italian network (Noto, Medicina and SRT) and extended to the European antennas (Torun, Yebes, Onsala), very long baseline interferometry (VLBI) observations were triggered at 22 GHz on five different occasions, four times prior to the giant flare, and once during its decay phase. Flux variations of 2 h duration were recorded during the first session. They correspond to a mini-flare that occurred close to the core 10 d before the onset of the giant flare. From the latest VLBI observation we infer that 4 d after the flare peak the jet emission was extended over 30 mas.

The Radio Occultation research program performed at the Medicina and Noto Radioastronomical Stations of the Istituto Nazionale di Astrofisica (INAF) - Istituto di Radioastronomia (IRA) includes observations of spacecraft by satellite and satellite by satellite events. The Lunar Radio Occultation (LRO) part of the program consists in collecting data of the lunar Total Electron Content (TEC), at different limb longitudes and at different time, in order to study long term variation of the Moon's ionosphere. The LRO program started at Medicina in September 2006 with the observation of the European probe SMART-1 during its impact on the lunar soil. It proceeded in 2007 with the observation of the lunar occultations of Saturn and Venus, and with the observation of Mars in 2008. On this occasion the probes Cassini, Venus Express, Mars Express, Mars Reconaissance Orbiter and Mars Odissey were respectively occulted by the moon. On Dec 1st 2008 a Venus lunar occultation occurred. On that occasion we performed the first Italian-VLBI (I-VLBI) tracking experiment by detecting the carrier signals coming from the Venus Express (VEX) spacecraft with both the IRA radiotelescopes together with the Matera antenna of the Italian Space Agency. The second part of the radio occultation program includes the observation of satellite by satellite occultation events, as well as mutual occultations of Jupiter satellites. These events are referred to as mutual phenomena (PHEMU). These observations are aimed to measure the radio flux variation during the occultation and to derive surface spatial characteristics such as Io's hot spots. In this work preliminary results of the Radio Occultation program will be presented.

Carlo Moreschi (1876-1921): co-founder of the journal "La Medicina del Lavoro" and often forgotten pioneer of modern medicine.

Carlo Moreschi (1876-1921) was founding co-editor of the journal "Il Lavoro" (now known as "La Medicina del Lavoro"), together with Luigi Devoto in 1901. Despite this fact, many of his pioneering contributions to 20th century scientific debate are not well known outside Italy. The aim of this paper therefore was to recall Moreschi' achievements and the groundbreaking work of this remarkable Italian physician. A comprehensive analysis was conducted on scientific papers written by Carlo Moreschi between 1901 and 1920, extending the investigation to his original manuscripts and private correspondence with family and colleagues. Careful examination of Moreschi's work reveals several studies in the field of social medicine, epidemiology of infectious diseases, general pathology and oncology. In particular, his main interest in haematology and immunology enabled Moreschi to be one of the first to understand the mechanisms of complement fixation and the formation pathways ofantiglobulin sera. In this manner, Moreschi significantly contributed to the work of Wassermann regarding the diagnosis of syphilis, as well as contributing to the discovery of the "antiglobulin test", first described by Coombs in 1945. Furthermore, Moreschi co-founded "Il Lavoro" and "Haematologica", the oldest journals in their respective fields. According to Devoto, Moreschi can be remembered as the archetype modern researcher and clinician. His role in the 20th century scientific debate and his pioneering work in the field of immunology and haematology, that are often forgotten due to his premature death, deserve to be reconsidered and re-assessed by the Italian and international scientific community.

A direct ultrasonic (US) and ozone (O3) combination (US/O3) process for the removal of two hormones, estrone (E1) and estriol (E3), in aqueous solutions was investigated. These two hormones were detected in a wastewater treatment plant effluent in Korea. It was found that the ultrasonic/ozone process showed a higher removal performance than the US and O3 process even though the O3 process also showed approximately the same removal efficiency after 60 min. Chemical oxygen demand/total organic carbon (CODcr/TOC) ratios for E1 and E3 decreased, indicating that biodegradability could be increased significantly in the US/O3 process. The optimal pH condition was determined above the neutral pH condition.

To analyze whether socioeconomic and clinical aspects and the aspects of healthy life habits are associated with the quality of life of persons living with HIV/AIDS. This is a cross-sectional exploratory quantitative research, with 227 persons living with HIV/AIDS, treated at two hospitals of reference between April 2012 and June 2014. We used structured questionnaires to assess socioeconomic aspects (gender, age, education level, marital status, race, socioeconomic status, dependents on family income, employment relationship), clinical parameters (time of disease diagnosis, use and time of medication, CD4 T-cell count, and viral load), and practice of physical exercise. To assess quality of life, we used the Quality of Life questionnaire (HAT-QoL). For characterization of the socioeconomic and clinical data and domains of quality of life, we conducted a descriptive analysis (simple frequency, averages, and standard deviations). We applied linear regression, following a hierarchical model for each domain of quality of life. The domains that presented lower averages for quality of life were financial concern, concern with confidentiality, general function, and satisfaction with life. We found associations with the variables of socioeconomic status and physical exercise, therapy, and physical exercise for the last two domains, consecutively. The quality of life of persons living with HIV/AIDS shows losses, especially in the financial and confidentiality areas, followed by general function of the body and satisfaction with life, in which socioeconomic and clinical aspects and healthy living habits, such as the practice of physical exercise, are determining factors for this reality. Analisar se aspectos socioeconômicos, clínicos e de hábitos de vida saudável estão associados à qualidade de vida em pessoas vivendo com HIV/aids. Pesquisa quantitativa exploratória de corte transversal, com 227 pessoas vivendo com HIV/aids, atendidos em dois hospitais de referência entre os períodos de abril 2012 a junho de 2014. Foram utilizados questionários estruturados para avaliar aspectos socioeconômicos (sexo, idade, escolaridade, estado civil, cor de pele, status socioeconômico, dependentes da renda familiar, vínculo empregatício), parâmetros clínicos (tempo de diagnóstico da doença, uso e tempo de medicação, contagem de células TCD4 e carga viral) e prática de exercício físico. Para avaliar qualidade de vida, utilizou-se o questionário Quality of Life (HAT-QoL). Para caracterização dos dados socioeconômicos, clínicos e domínios da qualidade de vida, conduzimos análise descritiva (frequência simples, médias e desvios-padrão). Aplicamos regressão linear, seguindo um modelo hierárquico para cada domínio da qualidade de vida. Os domínios que apresentaram menores médias para a qualidade de vida foram preocupação financeira, preocupação com sigilo, função geral e satisfação com a vida. Foram encontradas associações com as variáveis status socioeconômico e exercício físico; terapia; e exercício físico para os dois últimos domínios, consecutivamente. A qualidade de vida de pessoas vivendo com HIV/aids apresentam prejuízos, principalmente nas questões financeiras e de sigilo, seguidos da função geral do corpo e satisfações com a vida, em que os aspectos socioeconômicos, clínicos e hábitos de vida saudável, como a prática de exercício físico, são fatores determinantes para essa realidade.

To translate and perform a cross-cultural adaptation of the Snoring, Tiredness, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, and Gender (STOP-Bang) questionnaire so that it can be used as a screening tool for the diagnosis of obstructive sleep apnea in Brazil. Based on the principles of good practice for the translation and cross-cultural adaptation of such instruments, the protocol included the following steps: acquisition of authorization from the lead author of the original questionnaire; translation of the instrument to Brazilian Portuguese, carried out by two translators; reconciliation; back-translation to English, carried out by two English teachers who are fluent in Portuguese; review of the back-translation; harmonization; review and approval of the questionnaire by the original author; cognitive debriefing involving 14 patients who completed the questionnaire; analysis of the results; and review and preparation of the final version of the instrument approved by the review committee. The final version of the STOP-Bang questionnaire for use in Brazil showed a clarity score > 9 (on a scale of 1-10) for all of the questions. The Cronbach's alpha coefficient was 0.62, demonstrating the internal consistency of the instrument. The means and standard deviations of the age, body mass index, and neck circumference of the patients studied were 46.8 ± 11.2 years, 43.7 ± 8.5 kg/m2, and 41.3 ± 3.6 cm, respectively. The STOP-Bang questionnaire proved to be understandable, clear, and applicable. The original instrument and the translated version, cross-culturally adapted for use in Brazil, were consistently equivalent. Therefore, it can become a widely used screening tool for patients with suspected obstructive sleep apnea.

Renal function is one of the most consistent prognostic determinants in heart failure. The prognostic information it provides is independent of the ejection fraction and functional status. This article reviews the various renal function assessment measures, with special emphasis on the fact that the patient's clinical situation and response to the heart failure treatment should be considered for the correct interpretation of the results. Finally, we review the literature on the performance of tubular damage biomarkers. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Medicina Interna (SEMI). All rights reserved.

1997-01-01

Should the Russian Space Agency (RSA) not participate in the International Space Station (ISS) program, then the United States (U.S.) National Aeronautics and Space Administration (NASA) may choose to execute the ISS mission. However, in order to do this, NASA must build two new space vehicles, which must perform the functions that the Russian vehicles and hardware were to perform. These functions include periodic ISS orbit reboost, initial ISS attitude control, and U.S. On-Orbit Segment (USOS) control Moment gyroscope (CMG) momentum desaturation. The two new NASA vehicles that must perform these functions are called the U.S. control module (USCM) and the U.S. resupply module. This paper presents a design concept for the USCM GN&C subsystem, which must play a major role in ISS orbit reboost and initial attitude control, plus USOS CMG momentum desaturation. The proposed concept is structured similar to the USOS GN&C subsystem, by design. It is very robust, in that it allows the USCM to assume a variety of vehicle attitudes and stay power-positive. It has a storage/safe mode that places the USCM in a gravity-gradient orientation and keeps it there for extended periods of time without consuming a great deal of propellant. Simulation results are presented and discussed that show the soundness of the design approach. An equipment list is included that gives detailed information on the baselined GN&C components.

To identify and analyze the available evidence in the literature on the use of social networks in nursing work processes. An integrative review of the literature conducted in PubMed, CINAHL, EMBASE and LILACS databases in January 2016, using the descriptors social media, social networking, nursing, enfermagem, redes sociais, mídias sociais, and the keyword nursing practice, without year restriction. The sample consisted of 27 international articles which were published between 2011 and 2016. The social networks used were Facebook (66.5%), Twitter (30%) and WhatsApp (3.5%). In 70.5% of the studies, social networks were used for research purposes, in 18.5% they were used as a tool aimed to assist students in academic activities, and in 11% for executing interventions via the internet. Nurses have used social networks in their work processes such as Facebook, Twitter and WhatsApp to research, teach and watch. The articles show several benefits in using such tools in the nursing profession; however, ethical considerations regarding the use of social networks deserve further discussion.

The cultivation of four industrial hemp cultivars (Felina 32, Chamaeleon, Uso31, and Finola) was investigated for oil production in the north-east of Italy along two years. The oils of all cultivars resulted in rich amount of linoleic acid (ω-6) and α-linolenic acid (ω-3). Felina 32 and Chamaeleon oils exhibited the highest amount of linoleic acid (59%) and α-linolenic acid (18%). Finola and Uso31 oils resulted in the richest of γ-linolenic acid (5-6%). All hempseed oils presented high oxidation stability and an acceptable initial quality. It is suggested that these oils can be used to produce EFA dietary supplements high in ω-6 and ω-3 of vegetal origin.

To determine the effects of Pilates exercises on health-related quality of life (HRQOL) in individuals with juvenile idiopathic arthritis (JIA). Randomized, prospective, single-blind trial. Outpatient clinic of pediatric rheumatology and the rehabilitation department. Children (N=50) with JIA according to the International League of Associations for Rheumatology criteria. Participants were randomly assigned into 2 groups. In group I (n=25), the participants were given a conventional exercise program for 6 months. Patients in group II (n=25) participated in a Pilates exercise program for 6 months. The primary outcome measure was HRQOL, as measured by the Pediatric Quality of Life Inventory version 4.0 (PedsQL 4.0). The secondary outcome measures provided an estimate of the clinical relevance of the primary outcome results and included joint pain intensity (according to a 10-cm visual analog scale), disability (according to the Childhood Health Assessment Questionnaire), joint status (using the Pediatric Escola Paulista de Medicina Range of Motion Scale), and the total PedsQL 4.0 score. All participants completed the study. The scores of the PedsQL 4.0 differed significantly between groups, indicating that Pilates exercises increased these scores when compared with the conventional exercise program. Group II participants showed significant improvements in the 10-cm visual analog scale-joint pain, Childhood Health Assessment Questionnaire, and Pediatric Escola Paulista de Medicina Range of Motion Scale. The use of Pilates exercises had a positive physical and psychosocial impact on HRQOL in individuals with JIA. Future multicenter studies with a follow-up beyond the period of treatment using more objective parameters will be useful to support the results of the present study.

[The anti-philosophical anthropology in the Hippocratic treatise De Vetere Medicina (On Ancient Medicine)].

PubMed

Imai, Masahiro

2007-01-01

The Hippocratic treatise De Vetere Medicina (On Ancient Medicine) has been the focus of attention among classical scholars and historians of medicine. The author attacks in ch. 20 doctors and sophists who base their own medical theories and methods on philosophical anthropology taken from the contemporary natural philosophers. Many attempts have been made to elucidate, as opposed to their philosophical inquiry into human nature, the author's way of understanding it, which still remains unclear. I draw attention to the following points to make it clear that the conceptual framework of the author's medical anthropology is different from theirs. Their philosophical inquiry into human nature has its starting point in fundamental element(s), from which human beings were originally formed. The author focuses on human beings as existent in their present states, whose conditions and functions must be investigated through interrelations between them and their external factors, such as foods and drinks. A medical investigation into the interrelations will give us a scientific idea about human body, whose constituents are taken to be a large number of humors, reacting against some external factors and accordingly making us feel pain. This may presuppose that, in the author's medical anthropology, human body is conceptually demarcated as the physical or material aspect of human being, within which all physiological events depending on external factors and the humors take place. In their philosophical anthropology, however, human body doesn't seem to have been clearly conceptualized as such, because our experience of feeling pain should be judged to take place within the actions of the fundamental element(s), which must be supposed to constitute our cognitive self.

Older patients are prone to multimorbidity and polypharmacy, with an inherent risk of adverse events and drug interactions. To the best of our knowledge, available information on the appropriateness of lipid-lowering treatment is extremely limited. The aim of the present study was to quantify and characterize lipid-lowering drug use in a population of complex in-hospital older patients. We analyzed data from 87 units of internal medicine or geriatric medicine in the REPOSI (Registro Politerapie della Società Italiana di Medicina Interna) study, with reference to the 2010 and 2012 patient cohorts. Lipid-lowering drug use was closely correlated with the clinical profiles, including multimorbidity markers and polypharmacy. 2171 patients aged >65 years were enrolled (1057 males, 1114 females, mean age 78.6 years). The patients treated with lipid-lowering drugs amounted to 508 subjects (23.4%), with no gender difference. Atorvastatin (39.3%) and simvastatin (34.0%) were the most widely used statin drugs. Likelihood of treatment was associated with polypharmacy (≥5 drugs) and with higher Cumulative Illness Rating Scale (CIRS) score. At logistic regression analysis, the presence of coronary heart disease, peripheral vascular disease, and hypertension were significantly correlated with lipid-lowering drug use, whereas age showed an inverse correlation. Diabetes was not associated with drug treatment. In this in-hospital cohort, the use of lipid-lowering agents was mainly driven by patients' clinical history, most notably the presence of clinically overt manifestations of atherosclerosis. Increasing age seems to be associated with lower prescription rates. This might be indicative of cautious behavior towards a potentially toxic treatment regimen.

To identify the presence of phlebitis and the factors that influence the development of this complication in adult patients admitted to hospital in the western Brazilian Amazon. Exploratory study with a sample of 122 peripheral intravenous catheters inserted in 122 patients in a medical unit. Variables related to the patient and intravenous therapy were analyzed. For the analysis, we used chi-square tests of Pearson and Fisher exact test, with 5% significance level. Complication was the main reason for catheter removal (67.2%), phlebitis was the most frequent complication (31.1%). The mean duration of intravenous therapy use was 8.81 days in continuous and intermittent infusion (61.5%), in 20G catheter (39.3%), inserted in the dorsal hand vein arc (36.9 %), with mean time of usage of 68.4 hours. The type of infusion (p=0.044) and the presence of chronic disease (p=0.005) and infection (p=0.007) affected the development of phlebitis. There was a high frequency of phlebitis in the sample, being influenced by concomitant use of continuous and intermittent infusion of drugs and solutions, and more frequent in patients with chronic diseases and infection.

Foram analisadas variáveis relacionadas ao paciente e à terapia intravenosa. Para a análise utilizaram-se os testes de Qui-quadrado de Pearson e Exato de Fisher, com nível de significância de 5%. A complicação foi o principal motivo da retirada do cateter (67,2%), e a flebite a complicação mais frequente (31,1%). O tempo médio de uso de terapia intravenosa foi de 8,81 dias, em infusão contínua e intermitente (61,5%), em cateter calibre 20G (39,3%), inseridos nas veias do arco dorsal da mão (36,9%), com média de tempo de permanência de 68,4 horas. O tipo de infusão (p=0,044) e a presença de doença crônica (p=0,005) e de infecção (p=0,007) influenciaram o desenvolvimento de flebite. Houve alta frequência de flebite na amostra estudada, sendo influenciada pelo emprego concomitante de infusão contínua e intermitente de fármacos e soluções, e mais frequente em pacientes com doenças crônicas e infecção.

Seasonal availability of edible underground and aboveground carbohydrate resources to human foragers on the Cape south coast, South Africa.

The coastal environments of South Africa's Cape Floristic Region (CFR) provide some of the earliest and most abundant evidence for the emergence of cognitively modern humans. In particular, the south coast of the CFR provided a uniquely diverse resource base for hunter-gatherers, which included marine shellfish, game, and carbohydrate-bearing plants, especially those with Underground Storage Organs (USOs). It has been hypothesized that these resources underpinned the continuity of human occupation in the region since the Middle Pleistocene. Very little research has been conducted on the foraging potential of carbohydrate resources in the CFR. This study focuses on the seasonal availability of plants with edible carbohydrates at six-weekly intervals over a two-year period in four vegetation types on South Africa's Cape south coast. Different plant species were considered available to foragers if the edible carbohydrate was directly (i.e. above-ground edible portions) or indirectly (above-ground indications to below-ground edible portions) visible to an expert botanist familiar with this landscape. A total of 52 edible plant species were recorded across all vegetation types. Of these, 33 species were geophytes with edible USOs and 21 species had aboveground edible carbohydrates. Limestone Fynbos had the richest flora, followed by Strandveld, Renosterveld and lastly, Sand Fynbos. The availability of plant species differed across vegetation types and between survey years. The number of available USO species was highest for a six-month period from winter to early summer (Jul-Dec) across all vegetation types. Months of lowest species' availability were in mid-summer to early autumn (Jan-Apr); the early winter (May-Jun) values were variable, being highest in Limestone Fynbos. However, even during the late summer carbohydrate "crunch," 25 carbohydrate bearing species were visible across the four vegetation types. To establish a robust resource landscape will require additional spatial mapping of plant species abundances. Nonetheless, our results demonstrate that plant-based carbohydrate resources available to Stone Age foragers of the Cape south coast, especially USOs belonging to the Iridaceae family, are likely to have comprised a reliable and nutritious source of calories over most of the year.

To socialize an educational action through the process of group discussion and reflection, with the aim to increase the care of nursing workers in facing occupational risks. A qualitative descriptive study using the Convergent Care Research modality with nursing staff working in an emergency department of a hospital in the northwest region of the state of Rio Grande do Sul, Brazil. Data collection was carried out through educational workshops and information was processed using content analysis, resulting in two thematic categories: A look at the knowledge and practices about occupational risks in nursing; and adherence to protective measures by the nursing team against occupational risks. Twenty-four (24) workers participated in the study. When challenged to critically look at their actions, the subjects found that they relate the use of safety devices to situations in which they are aware of the patient's serological status. Subjects' interaction, involvement and co-responsibility in the health education process were determinant for their reflection on risky practices. They also had the potential to modify unsafe behaviors.

A coleta de dados foi realizada por meio de oficinas educativas, e o tratamento das informações, por análise de conteúdo, resultando em duas categorias temáticas: Um olhar direcionado a saberes e práticas sobre riscos ocupacionais na enfermagem e Adesão às medidas de proteção pela equipe de enfermagem frente aos riscos ocupacionais. Integraram o estudo 24 trabalhadores. Ao serem desafiados a olhar criticamente sobre seu fazer, os sujeitos constataram que vinculam o uso dos dispositivos de segurança a situações em que conhecem o status sorológico do paciente. A interação, o envolvimento e a corresponsabilização dos sujeitos no processo de educação em saúde foram determinantes para a reflexão das práticas de risco, bem como tiveram potencial para modificar comportamentos inseguros.

To analyze the prevalence and associated factors regarding the use of medicines by self-medication in Brazil. This cross-sectional population-based study was conducted using data from the PNAUM (National Survey on Access, Use and Promotion of Rational Use of Medicines), collected between September 2013 and February 2014 by interviews at the homes of the respondents. All people who reported using any medicines not prescribed by a doctor or dentist were classified as self-medication practitioners. Crude and adjusted prevalence ratios (Poisson regression) and their respective 95% confidence intervals were calculated in order to investigate the factors associated with the use of self-medication by medicines. The independent variables were: sociodemographic characteristics, health conditions and access to and use of health services. In addition, the most commonly consumed medicines by self-medication were individually identified. The self-medication prevalence in Brazil was 16.1% (95%CI 15.0-17.5), with it being highest in the Northeast region (23.8%; 95%CI 21.6-26.2). Following the adjusted analysis, self-medication was observed to be associated with females, inhabitants from the North, Northeast and Midwest regions and individuals that have had one, or two or more chronic diseases. Analgesics and muscle relaxants were the therapeutic groups most used for self-medication, with dipyrone being the most consumed medicines. In general, most of the medicines used for self-medication were classified as non-prescriptive (65.5%). Self-medication is common practice in Brazil and mainly involves the use of non-prescription medicines; therefore, the users of such should be made aware of the possible risks.

Este estudo transversal de base populacional foi realizado com dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de medicamentos (PNAUM), coletados de setembro de 2013 a fevereiro de 2014, por meio de entrevistas em domicílio. Todas as pessoas que referiram usar qualquer medicamento sem prescrição por médico ou dentista foram classificadas como praticantes de automedicação. Foram calculadas razões de prevalência bruta e ajustada (regressão de Poisson) e seus respectivos intervalos de confiança de 95% na investigação dos fatores associados ao consumo de medicamentos por automedicação. As variáveis independentes foram: aspectos sociodemográficos, de condições de saúde e de acesso e utilização de serviços de saúde. Adicionalmente, foram identificados os medicamentos mais consumidos por automedicação. A prevalência da automedicação no Brasil foi de 16,1% (IC95% 15,0-17,5), sendo maior na região Nordeste (23,8%; IC95% 21,6-26,2). Após análise ajustada, automedicação mostrou-se associada a ser do sexo feminino, pertencer às faixas etárias 10-19 anos, 20-29 anos, 40-59 anos e 60 anos ou mais, residir na região Norte, Nordeste ou Centro-Oeste, e ter uma ou duas ou mais doenças crônicas. Os analgésicos e os relaxantes musculares foram os grupos terapêuticos mais utilizados por automedicação, sendo a dipirona o fármaco mais consumido. No geral, a maioria dos medicamentos usados por automedicação foram classificados como isentos de prescrição (65,5%). A automedicação é prática corrente no Brasil e envolve, principalmente, o uso de medicamentos isentos de prescrição, devendo os usuários ficarem atentos aos seus possíveis riscos.

The importance of coronary anatomy in predicting cardiovascular events is well known. The use of traditional anatomical scores in routine angiography, however, has not been incorporated to clinical practice. SYNTAX score (SXscore) is a scoring system that estimates the anatomical extent of coronary artery disease (CAD). Its ability to predict outcomes based on a baseline diagnostic angiography has not been tested to date. To evaluate the performance of the SXscore in predicting major adverse cardiac events (MACE) in patients referred for diagnostic angiography. Prospective cohort of 895 patients with suspected CAD referred for elective diagnostic coronary angiography from 2008 to 2011, at a university-affiliated hospital in Brazil. They had their SXscores calculated and were stratified in three categories: no significant CAD (n = 495), SXscoreLOW-INTERMEDIATE: < 23 (n = 346), and SXscoreHIGH: ≥ 23 (n = 54). Primary outcome was a composite of cardiac death, myocardial infarction, and late revascularization. Secondary endpoints were the components of MACE and death from any cause. On average, patients were followed up for 1.8 ± 1.4 years. The primary outcome occurred in 2.2%, 15.3%, and 20.4% in groups with no significant CAD, SXscoreLOW-INTERMEDIATE, and SXscoreHIGH, respectively (p < 0.001). All-cause death was significantly higher in the SXscoreHIGH compared with the 'no significant CAD' group, 16.7% and 3.8% (p < 0.001), respectively. After adjustment for confounding factors, all outcomes remained associated with the SXscore. SXscore independently predicts MACE in patients submitted to diagnostic coronary angiography. Its routine use in this setting could identify patients with worse prognosis. A importância da anatomia coronariana na predição de eventos cardiovasculares é bem conhecida. O uso de escores anatômicos tradicionais na cineangiocoronariografia de rotina, entretanto, não foi incorporado à prática clínica. O SYNTAX escore (SXescore) é um sistema de escore que estima a extensão anatômica da doença arterial coronariana (DAC). Sua capacidade para predizer desfechos com base na cineangiocoronariografia diagnóstica de base ainda não foi testada. Avaliar o desempenho do SXescore para predizer eventos cardíacos adversos maiores (MACE) em pacientes encaminhados para cineangiocoronariografia diagnóstica. Coorte prospectiva de 895 pacientes com suspeita de DAC encaminhados para cineangiocoronariografia diagnóstica eletiva de 2008 a 2011, em hospital universitário no Brasil. Os pacientes tiveram seus SXescores calculados e foram estratificados em três categorias: 'sem DAC significativa' (n = 495); SXescoreBAIXO-INTERMEDIÁRIO: < 23 (n = 346); e SXescoreALTO: ≥ 23 (n = 54). O desfecho primário foi composto de morte cardíaca, infarto do miocárdio e revascularização tardia. Os desfechos secundários foram MACE e morte por todas as causas. Em média, os pacientes foram acompanhados por 1,8 ± 1,4 anos. Desfecho primário ocorreu em 2,2%, 15,3% e 20,4% nos grupos 'sem DAC significativa', SXescoreBAIXO-INTERMEDIÁRIO e SXescoreALTO, respectivamente (p < 0,001). Morte por todas as causas foi significativamente mais frequente no grupo de SXescoreALTO comparado ao grupo 'sem DAC significativa', 16,7% e 3,8% (p < 0,001), respectivamente. Após ajuste para fatores de confusão, todos os desfechos permaneceram associados com o SXescore. O SXescore prediz independentemente MACE em pacientes submetidos a cineangiocoronariografia diagnóstica. Seu uso rotineiro nesse contexto poderia identificar pacientes de pior prognóstico.

The concept of "Cosmography" is in disuse since the 80s of the last century, but the astronomical themes previously discussed in the school subjects of Geography and Cosmography remain in current textbooks. The use of term "Cosmography" was rescued in this research, and the study of its re-signification prompted the appearance of the term Geographic Cosmography. The Geographic Cosmography is a field of studies of the Geography, whose set of knowledge and skills is predominantly scholar. It studies the interface between terrestrial and celestial knowledge, and assigns a geographic significance to them. It examines human and natural relationships with Sidereal Space and its consequences for society and nature.

To determine the sociodemographic, behavioral, and health care factors related to the occurrence of syphilis in women treated at public maternity hospitals. This is a case-control study (239 cases and 322 controls) with women admitted to seven maternity hospitals in the municipality of Recife, Brazil, from July 2013 to July 2014. Eligible women were recruited after the result of the VDRL (Venereal Disease Research Laboratory) under any titration. The selection of cases and controls was based on the result of the serology for syphilis using ELISA (enzyme-linked immunosorbent assay). The independent variables were grouped into: sociodemographic, behavioral, clinical and obstetric history, and health care in prenatal care and maternity hospital. Information was obtained by interview, during hospitalization, with the application of a questionnaire. Odds ratios and 95% confidence intervals were estimated using logistic regression to identify the predicting factors of the variable to be explained. The logistic regression analysis identified as determinant factors for gestational syphilis: education level of incomplete basic education or illiterate (OR = 2.02), lack of access to telephone (OR = 2.4), catholic religion (OR = 1.70 ), four or more pregnancies (OR = 2.2), three or more sexual partners in the last year (OR = 3.1), use of illicit drugs before the age of 18 (OR = 3.0), and use of illicit drugs by the current partner (OR = 1.7). Only one to three prenatal appointments (OR = 3.5) and a previous history of sexually transmitted infection (OR = 9.7) were also identified as determinant factors. Sociodemographic, behavioral, and health care factors are associated with the occurrence of syphilis in women and should be taken into account in the elaboration of universal strategies aimed at the prevention and control of syphilis, but with a focus on situations of greater vulnerability. Determinar os fatores sociodemográficos, comportamentais e de assistência à saúde relacionados à ocorrência de sífilis em mulheres atendidas em maternidades públicas. Trata-se de um estudo caso-controle (239 casos e 322 controles) com mulheres admitidas em sete maternidades do município do Recife, no período de julho de 2013 a julho de 2014. As mulheres elegíveis foram recrutadas após o resultado do VDRL (Venereal Disease Research Laboratory) sob qualquer titulação. A seleção dos casos e controles considerou o resultado da sorologia por ELISA (enzyme-linked immunosorbent assay), variável dependente utilizada como diagnóstico para sífilis neste estudo. As variáveis independentes foram agrupadas em: sociodemográficas; comportamentais; e antecedentes clínicos e obstétricos; e assistência à saúde no pré-natal e na maternidade. As informações foram obtidas por meio de entrevista, durante o internamento, por aplicação de um questionário. Foi calculado odds ratio (OR), intervalo de confiança de 95% e realizada análise de regressão logística para identificar os fatores preditores da variável a ser explicada. A análise de regressão logística identificou como fatores determinantes para a sífilis gestacional: nível de escolaridade fundamental incompleto ou analfabeta (OR = 2,02), ausência de acesso a telefone (OR = 2,4), religião católica (OR = 1,70), quatro ou mais gestações (OR = 2,2), três ou mais parceiros sexuais no último ano (OR = 3,1), uso de drogas ilícitas antes dos 18 anos (OR = 3,0) e uso de drogas ilícitas por parte do atual companheiro (OR = 1,7). Além desses, foram observadas a ocorrência de apenas uma a três consultas ao pré-natal (OR = 3,5) e história anterior de infecção sexualmente transmissível (OR = 9,7). Fatores sociodemográficos, comportamentais e de assistência à saúde estão associados à ocorrência de sífilis em mulheres e devem ser levados em consideração na elaboração de estratégias universais direcionadas à prevenção e controle da sífilis, porém com foco em situações de maior vulnerabilidade.

Mars Global Surveyor Ka-Band Frequency Data Analysis

NASA Astrophysics Data System (ADS)

Morabito, D.; Butman, S.; Shambayati, S.

2000-01-01

The Mars Global Surveyor (MGS) spacecraft, launched on November 7, 1996, carries an experimental space-to-ground telecommunications link at Ka-band (32 GHz) along with the primary X-band (8.4 GHz) downlink. The signals are simultaneously transmitted from a 1.5-in diameter parabolic high gain antenna (HGA) on MGS and received by a beam-waveguide (BWG) R&D 34-meter antenna located in NASA's Goldstone Deep Space Network (DSN) complex near Barstow, California. The projected 5-dB link advantage of Ka-band relative to X-band was confirmed in previous reports using measurements of MGS signal strength data acquired during the first two years of the link experiment from December 1996 to December 1998. Analysis of X-band and Ka-band frequency data and difference frequency (fx-fka)/3.8 data will be presented here. On board the spacecraft, a low-power sample of the X-band downlink from the transponder is upconverted to 32 GHz, the Ka-band frequency, amplified to I-W using a Solid State Power Amplifier, and radiated from the dual X/Ka HGA. The X-band signal is amplified by one of two 25 W TWTAs. An upconverter first downconverts the 8.42 GHz X-band signal to 8 GHz and then multiplies using a X4 multiplier producing the 32 GHz Ka-band frequency. The frequency source selection is performed by an RF switch which can be commanded to select a VCO (Voltage Controlled Oscillator) or USO (Ultra-Stable Oscillator) reference. The Ka-band frequency can be either coherent with the X-band downlink reference or a hybrid combination of the USO and VCO derived frequencies. The data in this study were chosen such that the Ka-band signal is purely coherent with the X-band signal, that is the downconverter is driven by the same frequency source as the X-band downlink). The ground station used to acquire the data is DSS-13, a 34-meter BWG antenna which incorporates a series of mirrors inside beam waveguide tubes which guide the energy to a subterranean pedestal room, providing a stable environment for the feed and electronics equipment. A dichroic plate is used to reflect the X-band energy and pass the Ka-band energy to another mirror. The RF energy for each band is then focused onto a feed horn and low-noise amplifier package. After amplification and RF/IF downconversion, the IF signals are sent to the Experimental Tone Tracker (ETT), a digital phase-lock-loop receiver, which simultaneously tracks both X-band and Ka-band carrier signals. Once a signal is detected, the ETT outputs estimates of the SNR in a I -Hz bandwidth (Pc/No), baseband phase and frequency of the signals every I -sec. Between December 1996 and December 1998, the Ka-band and X-band signals from MGS were tracked on a regular basis using the ETT. The Ka-band downlink frequencies described here were referenced to the spacecraft's on-board USO which was also the X-band frequency reference (fka= 3.8 fx). The ETT estimates of baseband phase at I -second sampled time tags were converted to sky frequency estimates. Frequency residuals were then generated for each band by removing a model frequency from each observable frequency at each time tag. The model included Doppler and other effects derived from spacecraft trajectory files obtained from the MGS Navigation Team. A simple troposphere correction was applied to the data. In addition to residuals, the USO frequencies emitted by the spacecraft were estimated. For several passes, the USO frequencies were determined from X-band data and from Ka-band data (referred to X-band by dividing by 3.8) and were found to be in good agreement. In addition, X-band USO frequency estimates from MGS Radio Science data acquired from operational DSN stations were available for comparison and were found to agree within the I Hz level. The remaining sub-Hertz differences were attributed to the different models and software algorithms used by MGS Radio Science and KaBLE-11. A summary of the results of a linear fit of the USO frequency versus time (day of year) is presented in Table I for an initial segment of passes.

Aberdeen University was the first university in Great Britain to recognise the teaching of medicine by the creation of a teaching post, that of "mediciner." It was first occupied by James Cumyne, the burgh medical officer. The first medical degree granted by the university was doctus in medicina--learned in medicine. The degree was first awarded in 1630. The first examination paper for the M.D. was set in 1787 at the time of proposal to unit King's and Marischal Colleges and following criticism of the sale of degrees in medicine and midwifery "for ready money." The present degrees of M.B., ChB. were introduced in 1895.

Pulmonary hypertension and hepatic cirrhosis.

Pulmonary hypertension is a relatively common phenomenon in patients with hepatic cirrhosis and can appear through various mechanisms. The most characteristic scenario that binds portal and pulmonary hypertension is portopulmonary syndrome. However, hyperdynamic circulation, TIPS placement and heart failure can raise the mean pulmonary artery pressure without increasing the resistances. These conditions are not candidates for treatment with pulmonary vasodilators and require a specific therapy. A correct assessment of hemodynamic, ultrasound and clinical variables enables the differential diagnosis of each situation that produces pulmonary hypertension in patients with cirrhosis.

Several forms of experimental evidence gathered in the last 37 years have unequivocally established that the medulla oblongata harbors the main neural circuits responsible for generating the vasomotor tone and regulating arterial blood pressure. Our current understanding of this circuitry derives mainly from the studies of Pedro Guertzenstein, a former student who became Professor of Physiology at UNIFESP later, and his colleagues. In this review, we have summarized the main findings as well as our collaboration to a further understanding of the ventrolateral medulla and the control of arterial blood pressure under normal and pathological conditions.

In this pioneer study, 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) was used to improve the solubility of the diffractaic acid (DA) via inclusion complex (DA:HP-β-CD). Subsequently, DA:HP-β-CD was incorporated into poly-ε-caprolactone (PCL) microspheres (DA:HP-β-CD-MS). Microspheres containing DA (DA-MS) or DA:HP-β-CD (DA:HP-β-CD-MS) were prepared using the multiple W/O/W emulsion-solvent evaporation technique. The phase-solubility diagram of DA in HP-β-CD (10-50mM) showed an A L type curve with a stability constant K 1:1 =821M -1 . 1 H NMR, FTIR, X-ray diffraction and thermal analysis showed changes in the molecular environment of DA in DA:HP-β-CD. The molecular modeling approach suggests a guest-host complex formation between the carboxylic moiety of both DA and the host (HP-β-CD). The mean particle size of the microspheres were ∅ DA-MS =5.23±1.65μm and ∅ DA:HP-β-CD-MS =4.11±1.39μm, respectively. The zeta potential values of the microspheres were ζ DA-MS =-7.85±0.32mV and ζ DA:HP-β-CD-MS =-6.93±0.46mV. Moreover, the encapsulation of DA:HP-β-CD into microspheres resulted in a more slower release (k 2 =0.042±0.001; r 2 =0.996) when compared with DA-MS (k 2 =0.183±0.005; r 2 =0.996). The encapsulation of DA or DA:HP-β-CD into microspheres reduced the cytotoxicity of DA (IC 50 =43.29μM) against Vero cells (IC 50 of DA-MS=108.48μM and IC 50 of DA:HP-β-CD-MS=142.63μM).

Methamphetamine-induced neurotoxicity disrupts pharmacologically evoked dopamine transients in the dorsomedial and dorsolateral striatum.

Phasic dopamine (DA) signaling, during which burst firing by DA neurons generates short-lived elevations in extracellular DA in terminal fields called DA transients, is implicated in reinforcement learning. Disrupted phasic DA signaling is proposed to link DA depletions and cognitive-behavioral impairment in methamphetamine (METH)-induced neurotoxicity. Here, we further investigated this disruption by assessing effects of METH pretreatment on DA transients elicited by a drug cocktail of raclopride, a D2 DA receptor antagonist, and nomifensine, an inhibitor of the dopamine transporter (DAT). One advantage of this approach is that pharmacological activation provides a large, high-quality data set of transients elicited by endogenous burst firing of DA neurons for analysis of regional differences and neurotoxicity. These pharmacologically evoked DA transients were measured in the dorsomedial (DM) and dorsolateral (DL) striatum of urethane-anesthetized rats by fast-scan cyclic voltammetry. Electrically evoked DA levels were also recorded to quantify DA release and uptake, and DAT binding was determined by means of autoradiography to index DA denervation. Pharmacologically evoked DA transients in intact animals exhibited a greater amplitude and frequency and shorter duration in the DM compared to the DL striatum, despite similar pre- and post-drug assessments of DA release and uptake in both sub-regions as determined from the electrically evoked DA signals. METH pretreatment reduced transient activity. The most prominent effect of METH pretreatment on transients across striatal sub-region was decreased amplitude, which mirrored decreased DAT binding and was accompanied by decreased DA release. Overall, these results identify marked intrastriatal differences in the activity of DA transients that appear independent of presynaptic mechanisms for DA release and uptake and further support disrupted phasic DA signaling mediated by decreased DA release in rats with METH-induced neurotoxicity.

Striatal dopamine neurotransmission: regulation of release and uptake

PubMed Central

Sulzer, David; Cragg, Stephanie J.; Rice, Margaret E.

2016-01-01

Dopamine (DA) transmission is governed by processes that regulate release from axonal boutons in the forebrain and the somatodendritic compartment in midbrain, and by clearance by the DA transporter, diffusion, and extracellular metabolism. We review how axonal DA release is regulated by neuronal activity and by autoreceptors and heteroreceptors, and address how quantal release events are regulated in size and frequency. In brain regions densely innervated by DA axons, DA clearance is due predominantly to uptake by the DA transporter, whereas in cortex, midbrain, and other regions with relatively sparse DA inputs, the norepinephrine transporter and diffusion are involved. We discuss the role of DA uptake in restricting the sphere of influence of DA and in temporal accumulation of extracellular DA levels upon successive action potentials. The tonic discharge activity of DA neurons may be translated into a tonic extracellular DA level, whereas their bursting activity can generate discrete extracellular DA transients. PMID:27141430

Phasic dopamine (DA) signaling, during which burst firing by dopamine neurons generates short-lived elevations in extracellular DA in terminal fields called DA transients, is implicated in reinforcement learning. Disrupted phasic DA signaling is proposed to link DA depletions and cognitive-behavioral impairment in methamphetamine (METH)-induced neurotoxicity. Here we further investigated this disruption by assessing effects of METH pretreatment on DA transients elicited by a drug cocktail of raclopride, a D2 DA receptor antagonist, and nomifensine, an inhibitor of the dopamine transporter (DAT). One advantage of this approach is that pharmacological activation provides a large, high-quality data set of transients elicited by endogenous burst firing of DA neurons for analysis of regional differences and neurotoxicity. These pharmacologically evoked DA transients were measured in the dorsomedial (DM) and dorsolateral (DL) striatum of urethane-anesthetized rats by fast-scan cyclic voltammetry. Electrically evoked DA levels were also recorded to quantify DA release and uptake, and DAT binding was determined by autoradiography to index DA denervation. Pharmacologically evoked DA transients in intact animals exhibited a greater amplitude and frequency and shorter duration in the DM compared to the DL striatum, despite similar pre- and post-drug assessments of DA release and uptake in both sub-regions as determined from the electrically evoked DA signals. METH pretreatment reduced transient activity. The most prominent effect of METH pretreatment on transients across striatal sub-region was decreased amplitude, which mirrored decreased DAT binding and was accompanied by decreased DA release. Overall, these results identify marked intrastriatal differences in the activity of DA transients that appear independent of presynaptic mechanisms for DA release and uptake and further support disrupted phasic DA signaling mediated by decreased DA release in rats with METH-induced neurotoxicity.

Little is known about the quality and quantity of cost-utility analyses (CUAs) in Brazil. The objective of this study was to provide a systematic review of published CUAs of healthcare technologies in Brazil. We performed a systematic review of economic evaluations studies published in MEDLINE, EMBASE, LILACS (Latin American and Caribbean Health Sciences Literature), SciELO (Scientific Electronic Library Online), NHS EED (National Health Service Economic Evaluation Database), HTA (Health Technology Assessment) Database, Web of Science, Scopus, Bireme (Biblioteca Regional de Medicina), BVS ECOS (Health Economics database of the Brazilian Virtual Library of Health), and SISREBRATS (Sistema de Informação da Rede Brasileira de Avaliação de Tecnologias em Saúde [Brazilian Network for the Evaluation of Health Technologies]) from 1980 to 2013. Articles were included if they were CUAs according to the classification devised by Drummond et al. Two independent reviewers screened articles for relevance and carried out data extraction. Disagreements were resolved through discussion or through consultation with a third reviewer. We performed a qualitative narrative synthesis. Of the 535 health economic evaluations (HEEs) relating to Brazil, only 40 were CUAs and therefore included in the analysis. Most studies adhered to methodological guidelines for quality of reporting and 77.5% used quality-adjusted life-years (QALYs) as the health outcome. Of these studies, 51.6% did not report the population used to elicit preferences for outcomes and 45.2% used a specific population such as expert opinion. The preference elicitation method was not reported in 58.1% of these studies. The majority (80.6%) of studies did not report the instrument used to derive health state valuations and no publication reported whether tariffs (or preference weights) were national or international. No study mentioned the methodology used to estimate QALYs. Many published Brazilian cost-utility studies adhere to key recommended general methods for HEE; however, the use of QALY calculations is far from being the current international standard. Development of health preferences research can contribute to quality improvement of health technology assessment reports in Brazil.

It is important to know the reasons for resubmitting research projects to the Research Ethics Committee in order to help researchers to prepare their research projects, informed consent forms and needed research documentation. To verify the reasons for resubmitting projects that were previously rejected by the Ethics Committee. This is a cross-sectional study that evaluated research projects involving human beings. Research projects were submitted in 2007 to the Research Ethics Committee of the Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo. One thousand two hundred and fifty six research projects were submitted to the ethics committee and the average time for evaluating the research projects and related documents until a final decision was reached was 49.95 days. From the total, 399 projects were reviewed in 2 or more meetings until a final decision was reached. Of these, 392 research projects were included in the study; 35 projects were subsequently excluded for involving animals. Among the research projects included, 42.5% concerned research with new drugs, vaccines and diagnostic tests, 48.5% consisted of undergraduate students' research projects, 68.9% of the research had no sponsorship, and 97.5% were eventually approved. The main reasons for returning the projects to the researchers were the use of inadequate language and/or difficulty of understanding the informed consent form (32.2%), lack of information about the protocol at the informed consent form (25.8%), as well as doubts regarding methodological and statistical issues of the protocol (77.1%). Other reasons for returning the research projects involved lack of, inaccuracy on or incomplete documentation, need of clarification or approval for participation of external entities on the research, lack of information on financial support. Among the research projects that were returned to the researchers for additional clarification, the main reasons were inadequacies or doubts about the terms used in the informed consent form as well as lack of information regarding the research at the informed consent form and methodological and statistical issues regarding the protocol.

Proteomics is the study to identify the proteins involved in physiological metabolic pathway. The protein profiles of blood plasma from alloxan-induced diabetic rats has investigated using Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE). Data were analyzed descriptively based on variations of the type and intensity of the protein. There were identified the similarity of protein variant between diabetic and control rats included ankyrin (200kDa), IgG (150kDa), nephrin (136 kDa), IDE (112 kDA), albumin (66 kDa), prealbumin (55 kDA), CICP (43 kDa), ApoA-V (39 kDa), GAPDH (35 kDa), C-RP (27,1 kDa), leptin (16 kDa) and apelin (13 kDa). However, the apelin profile at diabetic rats shows the higher intensity than control.

Analysis of the mechanisms by which amphetamine releases dopamine from striatal dopaminergic neurons

The goals of the studies were (1) to determine the intraneuronal transmitter pools that contribute to the efflux of dopamine (DA) elicited by amphetamine (AMPH) and (2) to determine the biochemical mechanism by which AMPH increases DA efflux from dopaminergic neurons. AMPH increased the efflux of endogenous DA and decreased the electrically-evoked overflow of (/sup 3/H) acetylcholine (ACh) from superfused rabbit striatal slices. These effects were most pronounced when both vesicular DA stores and DA synthesis were intact. Therefore, extravesicular, newly synthesized DA and vesicular stores of DA contribute to AMPH-induced DA efflux. Simultaneous inhibition of monoamine oxidase (MAO) andmore » neuronal DA uptake did not increase the efflux of endogenous DA or inhibit the electrically-evoked overflow of (/sup 3/H)ACh to the same extent as AMPH. Hence, inhibition of MAO and neuronal DA uptake are probably not the major mechanisms by which AMPH increases DA efflux. The AMPH-induced efflux of endogenous or (/sup 3/H)DA was blocked by inhibitors of neuronal DA uptake.« less

Our recent studies have shown that the difference in basal pain sensitivity to mechanical and thermal stimulation between Dark-Agouti (DA) rats and a novel congenic DA.1U rats is major histocompatibility complex (MHC) genes dependent. In the present study, we further used DA and DA.1U rats to investigate the role of MHC genes in formalin-induced pain model by behavioral, electrophysiological and immunohistochemical methods. Behavioral results showed biphasic nociceptive behaviors increased significantly following the intraplantar injection of formalin in the hindpaw of DA and DA.1U rats. The main nociceptive behaviors were lifting and licking, especially in DA rats (P<0.001 and P<0.01). The composite pain scores (CPS) in DA rats were significantly higher than those in DA.1U rats in both phases of the formalin test (P<0.01). Electrophysiological results also showed the biphasic increase in discharge rates of C and Aδ fibers of L5 dorsal root in the two strains, and the net change of the discharge rate of DA rats was significantly higher than that of DA.1U rats (P<0.05). The mechanical thresholds decreased after formalin injection in both strains (P<0.01), and the net change in the mechanical threshold in DA was greater than that in DA.1U rats (P<0.05). The expression of RT1-B, representation of MHC class II molecule, in laminae I-II of L4/5 spinal cord in DA rats was significantly higher than that in DA.1U rats in the respective experimental group (P<0.05). These results suggested that both DA and DA.1U rats exhibited nociceptive responses in formalin-induced pain model and DA rats were more sensitive to noxious chemical stimulus than DA.1U rats, indicating that MHC genes might contribute to the difference in pain sensitivity.

Understanding differences in access and use of healthcare between international immigrants to Chile and the Chilean-born: a repeated cross-sectional population-based study in Chile

PubMed Central

2012-01-01

Introduction International evidence indicates consistently lower rates of access and use of healthcare by international immigrants. Factors associated with this phenomenon vary significantly depending on the context. Some research into the health of immigrants has been conducted in Latin America, mostly from a qualitative perspective. This population-based study is the first quantitative study to explore healthcare provision entitlement and use of healthcare services by immigrants in Chile and compare them to the Chilean-born. Methods Data come from the nationally representative CASEN (Socioeconomic characterization of the population in Chile) surveys, conducted in 2006 and 2009. Self-reported immigrants were compared to the Chilean-born, by demographic characteristics (age, sex, urban/rural, household composition, ethnicity), socioeconomic status (SES: education, household income, contractual status), healthcare provision entitlement (public, private, other, none), and use of primary services. Weighted descriptive, stratified and adjusted regression models were used to analyse factors associated with access to and use of healthcare. Results There was an increase in self-reported immigrant status and in household income inequality among immigrants between 2006 and 2009. Over time there was a decrease in the rate of immigrants reporting no healthcare provision and an increase in reporting of private healthcare provision entitlement. Compared to the Chilean-born, immigrants reported higher rates of use of antenatal and gynaecological care, lower use of well-baby care, and no difference in the use of Pap smears or the number of attentions received in the last three months. Immigrants in the bottom income quintile were four times more likely to report no healthcare provision than their equivalent Chilean-born group (with different health needs, i.e. vertical inequity). Disabled immigrants were more likely to have no healthcare provision compared to the disabled Chilean-born (with similar health needs, i.e. horizontal inequity). Factors associated with immigrants’ access to, and use of, healthcare were sex, urban/rural status, education and country of origin. Conclusion There were significant associations between SES, and access to and use of healthcare among immigrants in Chile and a higher prevalence of no health care provision entitlement among poor and disabled immigrants compared to the Chilean-born. Changing associations between access and use of healthcare and SES among immigrants in Chile over time may reflect changes in their socio-demographic composition or in the survey methodology between 2006 and 2009. Resumen Introducción La evidencia internacional indica menor acceso y uso de servicios de salud por parte de inmigrantes, pero sus factores desencadenantes varían significativamente dependiendo del contexto. Algunas investigaciones se han desarrollado en este tema en América Latina, desde una perspectiva cualitativa. Este estudio cuantitativo exploró el auto-reporte de acceso y uso de servicios de salud de inmigrantes en Chile y los comparó con la población chilena. Métodos Análisis secundario de datos de encuesta nacional CASEN 2006 y 2009. Inmigrantes fueron comparados con chilenos en características demográficas (edad, sexo, urbano/rural, composición del hogar, etnia), estatus socioeconómico (educación, ingreso, situación contractual), tipo de previsión (pública, privada, otra, ninguna), y uso de varios servicios de atención primaria. Análisis descriptivo, estratificado, y modelos de regresión ponderados para entender factores asociados al acceso y uso de servicios de salud en STATA 11.0. Resultados Se observó un aumento de reporte de inmigrantes y de la desigualdad en el ingreso de inmigrantes entre 2006 y 2009. Hubo una disminución en la tasa de inmigrantes sin previsión y un aumento en el acceso al sistema privado. Los inmigrantes usaron más frecuentemente la atención prenatal y ginecológica, y menos la atención del niño sano. No hubo diferencia en el uso de citología vaginal o el número total de atenciones recibidas en comparación con los chilenos. Los inmigrantes en el quintil inferior de ingresos reportaron 4 veces más la ausencia de prestación de salud que los chilenos (inequidad vertical). Similares resultados se observaron al comparar inmigrantes con discapacidad con chilenos con discapacidad (inequidad horizontal). Los factores asociados con el acceso y uso del servicio de salud por parte de los inmigrantes fueron el sexo, urbano/rural, educación y país de origen. Conclusión Se observó una asociación significativa entre estatus socioeconomico, migración y acceso y uso de asistencia sanitaria. Los resultados de este estudio pueden deberse a verdaderos cambios en la composición de los inmigrantes y sus patrones de uso del sistema de salud chileno, pero también pueden deberse a cambios en la metodología y recolección de datos entre encuestas 2006 y 2009. Este aspecto requiere mayor análisis y debate en la región. PMID:23158113

A recent study by the authors indicated that major histocompatibility complex (MHC) genes are associated with the differences in basal pain sensitivity and in formalin model between Dark-Agouti (DA) and novel congenic DA.1U rats, which have the same genetic background as DA rats except for the u alleles of MHC. The objective of the present study is to investigate whether there is a difference in the pristane-induced arthritis (PIA) model and local analgesic effect of octreotide (OCT) between DA and DA.1U rats. The hindpaw mechanical withdrawal threshold (MWT) and heat withdrawal latency (HWL) were observed. The C unit firings of the tibial nerve evoked by non-noxious and noxious toe movements were recorded by electrophysiological methods in normal and PIA models in DA and DA.1U rats before and after local OCT administration. The expression of somatostatin receptor 2A (SSTR2A) was observed by immunohistochemistry. The results demonstrate that DA rats have a higher mechanical sensitivity than DA.1U rats after PIA. Local OCT administration significantly elevated MWT in DA rats under normal and PIA sate, but not in DA.1U rats. The electrophysiological experiments showed OCT significantly attenuated the firings of C units evoked by non-noxious and noxious stimulation in DA rats more than those in DA.1U rats both in normal and PIA states. In addition, the expression of SSTR2A in the dorsal horn of the spinal cord was significantly higher in DA than in DA.1U rats. All of the findings suggest a higher local analgesic effect of OCT in DA rats than DA.1U rats, which might be associated with the MHC genes. © 2016 John Wiley & Sons Australia, Ltd.

METHAMPHETAMINE-INDUCED NEUROTOXICITY DISRUPTS NATURALLY OCCURRING PHASIC DOPAMINE SIGNALING

Methamphetamine (METH) is a highly addictive drug that is also neurotoxic to central dopamine (DA) systems. Although striatal DA depletions induced by METH are associated with behavioral and cognitive impairments, the link between these phenomena remains poorly understood. Previous work in both METH-pretreated animals and the 6-hydroxydopamine model of Parkinson’s disease suggests that a disruption of phasic DA signaling, which is important for learning and goal-directed behavior, may be such a link. However, prior studies used electrical stimulation to elicit phasic-like DA responses and were also performed under anesthesia, which alters DA neuron activity and presynaptic function. Here we investigated the consequences of METH-induced DA terminal loss on both electrically evoked phasic-like DA signals and so-called “spontaneous” phasic DA transients measured by voltammetry in awake rats. Not ostensibly attributable to discrete stimuli, these sub-second DA changes may play a role in enhancing reward-cue associations. METH-pretreatment reduced tissue DA content in the dorsomedial striatum and nucleus accumbens by ~55%. Analysis of phasic-like DA responses elicited by reinforcing stimulation revealed that METH pretreatment decreased their amplitude and underlying mechanisms for release and uptake to a similar degree as DA content in both striatal subregions. Most importantly, characteristics of DA transients were altered by METH-induced DA terminal loss, with amplitude and frequency decreased and duration increased. These results demonstrate for the first time that denervation of DA neurons alters naturally occurring DA transients and are consistent with diminished phasic DA signaling as a plausible mechanism linking METH-induced striatal DA depletions and cognitive deficits.

The International Space Station (ISS) United States Orbital Segment (USOS) Oxygen Generation System (OGS) was originally intended to be installed in ISS Node 3. The OGS rack delivery was accelerated, and it was launched to ISS in July of 2006 and installed in the US Laboratory Module. Various modification kits were installed to provide its interfaces, and the OGS was first activated in July of 2007 for 15 hours, In October of 2007 it was again activated for 76 hours with varied production rates and day/night cycling. Operational time in each instance was limited by the quantity of feedwater in a Payload Water Reservoir (PWR) bag. Feedwater will be provided by PWR bag until the USOS Water Recovery System (WRS) is delivered to SS in fall of 2008. This paper will discuss operating experience and characteristics of the OGS, as well as operational issues and their resolution.

The International Space Station (ISS) United States Operational Segment (USOS) received the first two permanent ISS Crew Quarters (CQ) on Utility Logistics Flight Two (ULF2) in November 2008. Up to four CQs can be installed into the Node 2 element to increase the ISS crewmember size to six. The CQs provide private crewmember space with enhanced acoustic noise mitigation, integrated radiation reduction material, communication equipment, redundant electrical systems, and redundant caution and warning systems. The racksized CQ is a system with multiple crewmember restraints, adjustable lighting, controllable ventilation, and interfaces that allow each crewmember to personalize their CQ workspace. The deployment and initial operational checkout during integration of the ISS CQ to the Node is described. Additionally, the comparison of on-orbit to original design performance is outlined for the following key operational parameters: interior acoustic performance, air flow rate, temperature rise, and crewmember feedback on provisioning and restraint layout.

Somatodendritic dopamine release: recent mechanistic insights

PubMed Central

Rice, Margaret E.; Patel, Jyoti C.

2015-01-01

Dopamine (DA) is a key transmitter in motor, reward and cogitative pathways, with DA dysfunction implicated in disorders including Parkinson's disease and addiction. Located in midbrain, DA neurons of the substantia nigra pars compacta project via the medial forebrain bundle to the dorsal striatum (caudate putamen), and DA neurons in the adjacent ventral tegmental area project to the ventral striatum (nucleus accumbens) and prefrontal cortex. In addition to classical vesicular release from axons, midbrain DA neurons exhibit DA release from their cell bodies and dendrites. Somatodendritic DA release leads to activation of D2 DA autoreceptors on DA neurons that inhibit their firing via G-protein-coupled inwardly rectifying K+ channels. This helps determine patterns of DA signalling at distant axonal release sites. Somatodendritically released DA also acts via volume transmission to extrasynaptic receptors that modulate local transmitter release and neuronal activity in the midbrain. Thus, somatodendritic release is a pivotal intrinsic feature of DA neurons that must be well defined in order to fully understand the physiology and pathophysiology of DA pathways. Here, we review recent mechanistic aspects of somatodendritic DA release, with particular emphasis on the Ca2+ dependence of release and the potential role of exocytotic proteins. PMID:26009764

Nicotine- and methamphetamine-induced dopamine release evaluated with in-vivo binding of radiolabelled raclopride to dopamine D2 receptors: comparison with in-vivo microdialysis data.

The effect of substances which alter extracellular dopamine (DA) concentration has been studied by measuring changes in the binding of radiolabelled raclopride, a DA D2 receptor ligand that is sensitive to endogenous DA. To better characterize the relationship between extracellular DA concentration and DA D2 receptor binding of raclopride, we compared the changes of extracellular DA concentration (measured using in-vivo microdialysis) and in-vivo [3H]raclopride binding induced by different doses of methamphetamine (Meth) and nicotine, drugs that enhance DA release with and without blocking DA transporters (DATs), respectively, in rat striatum. Nicotine elicited a modest increase of striatal extrasynaptic extracellular DA, while Meth produced a marked increase of striatal extrasynaptic DA in a dose-dependent manner. There was a close correlation between the decrease in [3H]raclopride in-vivo binding and the increase in extrasynaptic DA concentration induced by both nicotine (r2=0.95, p<0.001) and Meth (r2=0.98, p=0.001), supporting the usefulness of the radiolabelled raclopride-binding measurement for the non-invasive assessment of DA release following interventions in the living brain. However, the linear regression analysis revealed that the ratio of percent DA increase to percent [3H]raclopride binding reduction was 25-fold higher for Meth (34.8:1) than for nicotine (1.4:1). The apparent discrepancy in the extrasynaptic DA-[3H]raclopride binding relationship between the DA-enhancing drugs with and without DAT-blocking property indicates that the competition between endogenous DA and radiolabelled raclopride takes place at the intrasynaptic rather than extrasynaptic DA D2 receptors and reflects synaptic concentration of DA.

International Space Station USOS Potable Water Dispenser On-Orbit Functionality Versus Design

NASA Technical Reports Server (NTRS)

Toon, Katherine P.; Lovell, Randal W.

2010-01-01

The International Space Station (ISS) currently provides potable water dispensing for rehydrating crewmember food and drinking packages. There is one system located in the United States On-orbit Segment (USOS) and one system in the Russian Segment. Shuttle mission STS-126 delivered the USOS Potable Water Dispenser (PWD) to ISS on ULF2; subsequent activation occurred on November 2008. The PWD is capable of supporting an ISS crew of six, but nominally supplies only half this crew size. The PWD design provides incremental quantities of hot and ambient temperature potable water to US food and beverage packages. PWD receives iodinated water from the US Water Recovery System (WRS) Fuel Cell Water Bus, which feeds from the Water Processing Assembly (WPA). The PWD removes the biocidal iodine to make the water potable prior to dispensing. A heater assembly contained within the unit supplies up to 2.0 L of hot water (65 to 93 ?C) every 30 min. During a single meal, this quantity of water supports three to four crewmembers? food rehydration and beverages. The unit design has a functional life expectancy of 10 years, with replacement of limited life items, such as filters. To date, the PWD on-orbit performance is acceptable. Since activation of the PWD, there were several differences between on-orbit functionality and expected performance of hardware design. The comparison of on-orbit functionality to performance of hardware design is discussed for the following key areas: 1) microbial contamination, 2) no-dispense and water leakage scenarios, and 3) under-dispense scenarios.

The nuclear receptor related 1 (Nurr1) transcription factor contributes to the development and maintenance of dopamine (DA) neurons in the brain. We found that heterozygous Nurr1 knock-out (Nurr1 +/−) influenced the age-dependent decline in the number of DA neurons and influenced DA signaling. We examined the DA marker, tyrosine hydroxylase, using immunohistochemistry, and we measured DA signaling using fast-scan cyclic voltammetry in 3 age groups of wild-type (Nurr1 +/+) and mutant (Nurr1 +/−) mice: 3–6, 9–12, and 15–23 months old. Prior to significant loss of DA neurons and to the onset of parkinsonian symptoms, young Nurr1 +/− mice (3–6 months) exhibited a decrease in peak evoked DA release that was partially countered by a decrease in the rate of DA reuptake. As peak evoked DA release declined with age for both the wild-type and Nurr1 +/− mice, both genotypes manifested decreased DA reuptake. As the DA release fell further with age, decreased DA reuptake eventually could not adequately compensate the Nurr1 +/− mice. The results indicated that Nurr1 deficiency led to impaired DA release even before significant DA neuron loss. PMID:21531044

Summary of the Science Performed Onboard the International Space Station within the United States Orbital Segment during Increments 16 and 17

With the launch of the STS-122 on February 7, 2008, which delivered the European Columbus science module and the upcoming STS-124 flight, which will deliver the Japanese Kibo science module in May 2008, the International Space Station will become truly International with Europe and Japan joining the United States of America and Russia to perform science on a continuous basis in a wide spectrum of science disciplines. The last science module, Kibo, of the United States Orbital Segment (USOS) will be mated to the station on time to celebrate its first decade in low Earth orbit in October 2008 (end of Increment 17), thus ushering in the second decade of the station with all the USOS science modules mated and performing science. The arrival of the Kibo science module will also mark continuous human presence on the station for eighty eight (88) months, and, with the addition of the ESA science module during the STS-122 flight, the USOS will be made up of four space agencies: CSA, ESA, JAXA and NASA, spanning three continents. With the additional partners coming onboard with different research needs, every effort is being made to coordinate science across the USOS segment in an integrated manner for the benefit of all parties. One of the objectives of this paper is to discuss the integrated manner in which science planning/replanning and prioritization during the execution phase of an increment is being done. The main focus, though, of this paper is to summarize and to discuss the science performed during Increments 16 and 17 (October 2007 to October 2008). The discussion will focus mainly on the primary objectives of each investigation and their associated hypotheses that were investigated during these two Increments. Also, preliminary science results will be discussed for each of the investigation as science results availability permit. Additionally, the paper will briefly touch on what the science complement for these two increments was and what was actually accomplished due to real time science implementation and constraints. Finally, the paper will briefly discuss the science research complements for the next three Increments: Increments 18 to 20, in order to preview how much science might be accomplished during these three upcoming Increments of the station next decade.

Autocorrelation descriptor improvements for QSAR: 2DA_Sign and 3DA_Sign

Sliwoski, Gregory; Mendenhall, Jeffrey; Meiler, Jens

2016-03-01

Quantitative structure-activity relationship (QSAR) is a branch of computer aided drug discovery that relates chemical structures to biological activity. Two well established and related QSAR descriptors are two- and three-dimensional autocorrelation (2DA and 3DA). These descriptors encode the relative position of atoms or atom properties by calculating the separation between atom pairs in terms of number of bonds (2DA) or Euclidean distance (3DA). The sums of all values computed for a given small molecule are collected in a histogram. Atom properties can be added with a coefficient that is the product of atom properties for each pair. This procedure can lead to information loss when signed atom properties are considered such as partial charge. For example, the product of two positive charges is indistinguishable from the product of two equivalent negative charges. In this paper, we present variations of 2DA and 3DA called 2DA_Sign and 3DA_Sign that avoid information loss by splitting unique sign pairs into individual histograms. We evaluate these variations with models trained on nine datasets spanning a range of drug target classes. Both 2DA_Sign and 3DA_Sign significantly increase model performance across all datasets when compared with traditional 2DA and 3DA. Lastly, we find that limiting 3DA_Sign to maximum atom pair distances of 6 Å instead of 12 Å further increases model performance, suggesting that conformational flexibility may hinder performance with longer 3DA descriptors. Consistent with this finding, limiting the number of bonds in 2DA_Sign from 11 to 5 fails to improve performance.

Data administration (DA) is a position that has emerged with the growth of information technologies. A review of DA literature confirms that, although DA is widely associated with database management systems (DBMS), there is no standard DA job description, DA staffing and location within the organization vary, and DA functions range in description…

From sanddabs to blue whales: the pervasiveness of domoic acid.

Domoic acid (DA) is a potent food web transferred algal toxin that has caused dramatic mortality events involving sea birds and sea lions. Although no confirmed DA toxicity events have been reported in whales, here we present data demonstrating that humpback and blue whales are exposed to the toxin and consume DA contaminated prey. Whale fecal samples were found to contain DA at levels ranging from 10 to 207microg DA g(-1) feces via HPLC-UV methods. SEM analysis of whale feces containing DA, collected from krill-feeding whales, revealed the presence of diatom frustules identified as Pseudo-nitzschia australis, a known DA producer. Humpback whales were observed feeding on anchovies and sardines that contained DA at levels ranging from 75 to 444microg DA g(-1) viscera. DA contamination of whale feces and fish occurred only during blooms of toxic Pseudo-nitzschia. Additionally, several novel fish species collected during a toxic diatom bloom were tested for DA. Fish as diverse as benthic sanddabs and pelagic albacore were found to contain the neurotoxin, suggesting that DA permeates benthic as well as pelagic communities.

Vibrio cholerae O1 grown in heart infusion broth produces two forms of El Tor hemolysin (ETH) monomers of 65 and 50 kDa. These monomers form several different sizes of mixed oligomers ranging from 180 to 280 kDa in the liposomal membranes. We found that the N-terminal amino acid sequences, NH2-Trp-Pro-Ala-Pro-Ala-Asn-Ser-Glu, of both the 65- and 50-kDa toxins were identical. We assumed, therefore, that the 65- and 50-kDa toxins were derivatives of the identical precursor protein and the 50-kDa protein was a truncated derivative of 65-kDa ETH. To substantiate this assumption, we treated the 260-kDa oligomer with trypsin and obtained a 190-kDa oligomer. This 190-kDa oligomer consisted of only the 50-kDa subunits. Both 260- and 190-kDa oligomers formed ion channels indistinguishable from each other in planar lipid bilayers. These results suggest that the essential part of the ETH in forming the membrane-damaging aggregate is a 50-kDa protein.

La relación médico-paciente es la piedra angular de la práctica y ética médicas. Para alcanzar el respeto por los adultos mayores es necesaria una medicina prudente, basada en una práctica en la cual la reflexión ética y clínica pueda contribuir. Esto último es posible si se hacen valer los derechos del adulto mayor, en particular como paciente para la toma de decisiones. PMID:20379380

There is a rising interest for clinical cases in medicine. Actually, they don't necessarily conflict with the evidence-based medicine approach; rather, as several authors made clear, EBM-oriented case reports and clinical trials could be complementary. Cases and case series could even represent the first line of evidence and they are extremely valuable in discovering new pathologies and monitoring unexpected drug effects. They also play a relevant role in continuing medical education. The new section of Recenti Progressi in Medicina is edited by a prominent Italian research Institute (Istituto di Fisiologia Clinica, CNR). It focuses on a single case, guiding the physicians' decision-making from differential diagnosis to the treatment options.

Nowadays surgery cannot be conceived as independent from medicine; consequently, surgical education cannot be far from the main principles of medical education. This review underlines the characteristics of medical training in the field of surgery. General physicians should be trained to perform surgical procedures under particular situations. A new lesson plan was implemented at the Facultad de Medicina in Mexico City (UNAM), comprised of eight fundamental surgical skills. A well-structured surgical program implies clear and exact definitions of the skills to be acquired during training as well as an appropriate follow-up, knowledge reinforcement, continuing educational skills, application of medical tests for patient care and evaluation of the learning process.

Autoinflammatory diseases are clinical conditions with inflammatory manifestations that present in a periodic or persistent manner and are caused by acquired or hereditary disorders of the innate immune response. In general, these diseases are more common in childhood, but cases have been reported in adults and are therefore important for all specialists. There are few references on these diseases in adults due to their low prevalence and underdiagnosis. The aim of this study is to review the scientific literature on these disorders to systematise their clinical, prognostic and treatment response characteristics in adults.

The Italian physician and botanist Prospero Alpini (1553-1617) is considered as one of the most famous 16th Century Italian botanists having explored the plant species of Egypt and the Near East. Alpinis best-known works as for example De medicina Egyptiorum (Venetijs 1591) or De plantis Aegypti liber (Venetijs 1592), however, wouldn't certainly have been made possible without the influence of his academic teacher, the Prussian physician and botanist Melchior Wieland (ca. 1520-1589), having been applied director of the botanical garden of Padua in 1561. This study is therefore dedicated to the life, academic career, works and reception of this nearly forgotten botanist.

The neutron star X-ray binary Aql X-1 is currently in outburst (ATel #5114, #5117, #5129, #5136, #5148). Using the European VLBI Network (e-EVN) we observed Aql X-1 at 5 GHz in two time-slots: 2013 June 18 between 19:48 - 20:36 UT (MJD 56461.825 - 56461.858), and 2013 June 19 between 02:53 - 05:54 UT (MJD 56462.120 - 56462.246). The two datasets were combined together and then calibrated. The participating radio telescopes were: Effelsberg (Germany), Jodrell Bank Mk2 (UK), Medicina (Italy), Noto (Italy), Onsala 25m (Sweden), Torun (Poland), Yebes (Spain), Westerbork Synthesis Radio Telescope (Netherlands), Shanghai (China), Hartebeesthoek (South Africa).

Research in the critically ill is complex by the heterogeneity of patients, the difficulties to achieve representative sample sizes and the number of variables simultaneously involved. However, the quantity and quality of records is high as well as the relevance of the variables used, such as survival. The methodological tools have evolved to offering new perspectives and analysis models that allow extracting relevant information from the data that accompanies the critically ill patient. The need for training in methodology and interpretation of results is an important challenge for the intensivists who wish to be updated on the research developments and clinical advances in Intensive Medicine.

We present preliminary results for our study of mutual phenomena of the Galilean satellites performed at radio wavelengths with the Medicina and Noto antennas of the Istituto di Radioastronomia \\textendash{} INAF, and with the Effelsberg 100-m radio telescope of the Max-Planck-Institute for Radioastronomy. Measurements of the radio flux density variation occurred during the mutual occultations of Io by Europa and Ganymede were carried out during the PHEMU09 campaign at K- and Q-band. Flux density variations observed for the first time at radio wavelengths are consistent with the typical optical patterns measured when partial occultations occurred. The flux density drops indicate a non-linear dependence with the percentage of overlapped area.

We report on extremely high radio flux of BL Lacertae at 43 and 8 GHz. Observations at 43 GHz with the 32 m radio telescope in Noto (Italy) revealed a flux density of 10.5 +/- 0.2 Jy on 2013 April 10.65, while observations at 8 GHz with the 32 m radio telescope in Medicina (Italy) detected a flux density of 8.2 +/- 0.7 Jy on April 12.22. These extremely high radio fluxes show that the radio activity likely correlated to the strong optical, near-infrared, and gamma-ray activity of 2011-2012 (see ATels #4028, #4031, #4155, #4271, #4277, #4349, #4565, #4600), and X-ray activity of late 2012 (ATels #4557, #4627), is far to be exhausted.

Studies with latest technologies such as endoscopy with magnification and chromoendoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. To validate the morphologic features of gastric mucosa related to H. pylori infection gastritis allowing predictability of their diagnosis as well as proper targeting biopsies. Prospective study of 339 consecutive patients with the standard videoendoscope image analysis were obtained, recorded and stored in a program database. These images were studied with respect to the presence or absence of H. pylori, diagnosed by rapid urease test and/or by histological analysis. Were studied: a) normal mucosa appearance; b) mucosal nodularity; c) diffuse nonspecific erythema or redness (with or without edema of folds and exudate) of antrum and body; d) mosaic pattern with focal area of hyperemia; e) erythema in streaks or bands (red streak); f) elevated (raised) erosion; g) flat erosions; h) fundic gland polyps. The main exclusion criteria were the use of drugs, HP pre-treatment and other entities that could affect results. Applying the exclusion criteria, were included 170 of the 339 patients, of which 52 (30.58%) were positive for HP and 118 negative. On the positive findings, the most associated with infection were: nodularity in the antrum (26.92%); presence of raised erosion (15.38%) and mosaic mucosa in the body (21.15%). On the negative group the normal appearance of the mucosa was 66.94%; erythema in streaks or bands in 9.32%; flat erosions 11.86%; and fundic gland polyps 11.86%. Endoscopic findings are useful in the predictability of the result and in directing biopsies. The most representative form of HP related gastritis was the nodularity of the antral mucosa. The raised erosion and mucosa in mosaic in the body are suggestive but not specific to the infection. The other forms were not conclusive of the presence of HP. Estudos com tecnologias mais recentes como endoscopia com magnificação e cromoscopia mostraram que vários aspectos endoscópicos estão claramente associados à infecção por Helicobacter pylori. A descrição de padrões diferenciados de enantema no corpo gástrico através da magnificação de imagens reavivou o interesse na identificação desses padrões pela endoscopia convencional. Validar os padrões morfológicos de mucosa gástrica usando videogastroendoscopia convencional relacionados à gastrite por infecção por Helicobacter pylori, permitindo previsibilidade do seu diagnóstico e o direcionamento de biópsias. Estudo prospectivo de 339 pacientes consecutivos com análise das imagens de videogastroendoscopia obtidas, gravadas e armazenadas em banco de dados. Estas imagens foram estudadas com relação à presença ou não do Helicobacter pylori diagnosticado por teste rápido de urease e/ou por pesquisa direta por estudo anatomopatológico. Foram estudados: a) aspecto normal da mucosa; b) nodularidade da mucosa; c) enantema inespecífico difuso de antro e corpo; d) enantema em mosaico ou salpicado; e) enantema em estrias ou faixas; f) erosões elevadas; g) erosões planas; h) pólipos de glândulas fúndicas. Os principais critérios de exclusão foram o uso de medicamentos, tratamento prévio de HP e outras entidades que pudessem interferir nos resultados. Aplicando os critérios de exclusão, incluíram-se 170 dos 339 pacientes sendo 52 (30,58%) positivos para Helicobacter pylori e 118 negativos. No grupo positivo os achados que mais se associaram com a infecção foram: nodularidade no antro (26,92%); presença de erosões elevadas (15,38%) e mucosa em mosaico no corpo (21,15%). No grupo negativo o aspecto normal da mucosa foi de 66,94%; enantema em estrias ou faixas em 9,32%; erosões planas em 11,86%; e pólipos de glândulas fúndicas 11,86%. Achados endoscópicos são úteis na previsibilidade de localização e direcionamento de biópsias na pesquisa do HP. A mais representativa forma de gastrite por HP foi o achado de nodularidade na mucosa antral. As erosões elevadas e mucosa em mosaico no corpo são sugestivas, mas não específicas da infecção. As demais formas não foram conclusivas da presença do HP.

This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was -0.4% (95% confidence interval, -9.8% to 9.1%), which was above the non-inferiority margin of -14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601. DA-5204 is as effective as DA-9601 in the treatment of erosive gastritis. Registered randomized clinical trial at ClinicalTrials.gov (NCT02282670). © 2017 The Korean Academy of Medical Sciences.

The ductus arteriosus (DA) is a fetal shunt vessel between the pulmonary artery and the aorta that closes promptly after birth. Failure of postnatal DA closure is a major cause of morbidity and mortality particularly in preterm neonates. The events leading to DA closure are incompletely understood. Here we show that platelets have an essential role in DA closure. Using intravital microscopy of neonatal mice, we observed that platelets are recruited to the luminal aspect of the DA during closure. DA closure is impaired in neonates with malfunctioning platelet adhesion or aggregation or with defective platelet biogenesis. Defective DA closure resulted in a left-to-right shunt with increased pulmonary perfusion, pulmonary vascular remodeling and right ventricular hypertrophy. Our findings indicate that platelets are crucial for DA closure by promoting thrombotic sealing of the constricted DA and by supporting luminal remodeling. A retrospective clinical study revealed that thrombocytopenia is an independent predictor for failure of DA closure in preterm human newborns, indicating that platelets are likely to contribute to DA closure in humans.

An integrative theory of the phasic and tonic modes of dopamine modulation in the prefrontal cortex.

PubMed

Dreher, Jean-Claude; Burnod, Yves

2002-01-01

This paper presents a model of both tonic and phasic dopamine (DA) effects on maintenance of working memory representations in the prefrontal cortex (PFC). The central hypothesis is that DA modulates the efficacy of inputs to prefrontal pyramidal neurons to prevent interferences for active maintenance. Phasic DA release, due to DA neurons discharges, acts at a short time-scale (a few seconds), while the tonic mode of DA release, independent of DA neurons firing, acts at a long time-scale (a few minutes). The overall effect of DA modulation is modeled as a threshold restricting incoming inputs arriving on PFC neurons. Phasic DA release temporary increases this threshold while tonic DA release progressively increases the basal level of this threshold. Thus, unlike the previous gating theory of phasic DA release, proposing that it facilitates incoming inputs at the time of their arrival, the effect of phasic DA release is supposed to restrict incoming inputs during a period of time after DA neuron discharges. The model links the cellular and behavioral levels during performance of a working memory task. It allows us to understand why a critical range of DA D1 receptors stimulation is required for optimal working memory performance and how D1 receptor agonists (respectively antagonists) increase perseverations (respectively distractability). Finally, the model leads to several testable predictions, including that the PFC regulates DA neurons firing rate to adapt to the delay of the task and that increase in tonic DA release may either improve or decrease performance, depending on the level of DA receptors stimulation at the beginning of the task.

Neurobiological model of stimulated dopamine neurotransmission to interpret fast-scan cyclic voltammetry data.

PubMed

Harun, Rashed; Grassi, Christine M; Munoz, Miranda J; Torres, Gonzalo E; Wagner, Amy K

2015-03-02

Fast-scan cyclic voltammetry (FSCV) is an electrochemical method that can assess real-time in vivo dopamine (DA) concentration changes to study the kinetics of DA neurotransmission. Electrical stimulation of dopaminergic (DAergic) pathways can elicit FSCV DA responses that largely reflect a balance of DA release and reuptake. Interpretation of these evoked DA responses requires a framework to discern the contribution of DA release and reuptake. The current, widely implemented interpretive framework for doing so is the Michaelis-Menten (M-M) model, which is grounded on two assumptions- (1) DA release rate is constant during stimulation, and (2) DA reuptake occurs through dopamine transporters (DAT) in a manner consistent with M-M enzyme kinetics. Though the M-M model can simulate evoked DA responses that rise convexly, response types that predominate in the ventral striatum, the M-M model cannot simulate dorsal striatal responses that rise concavely. Based on current neurotransmission principles and experimental FSCV data, we developed a novel, quantitative, neurobiological framework to interpret DA responses that assumes DA release decreases exponentially during stimulation and continues post-stimulation at a diminishing rate. Our model also incorporates dynamic M-M kinetics to describe DA reuptake as a process of decreasing reuptake efficiency. We demonstrate that this quantitative, neurobiological model is an extension of the traditional M-M model that can simulate heterogeneous regional DA responses following manipulation of stimulation duration, frequency, and DA pharmacology. The proposed model can advance our interpretive framework for future in vivo FSCV studies examining regional DA kinetics and their alteration by disease and DA pharmacology.

Optogenetic versus electrical stimulation of dopamine terminals in the nucleus accumbens reveals local modulation of presynaptic release

PubMed Central

2015-01-01

The nucleus accumbens is highly heterogeneous, integrating regionally distinct afferent projections and accumbal interneurons, resulting in diverse local microenvironments. Dopamine (DA) neuron terminals similarly express a heterogeneous collection of terminal receptors that modulate DA signaling. Cyclic voltammetry is often used to probe DA terminal dynamics in brain slice preparations; however, this method traditionally requires electrical stimulation to induce DA release. Electrical stimulation excites all of the neuronal processes in the stimulation field, potentially introducing simultaneous, multi-synaptic modulation of DA terminal release. We used optogenetics to selectively stimulate DA terminals and used voltammetry to compare DA responses from electrical and optical stimulation of the same area of tissue around a recording electrode. We found that with multiple pulse stimulation trains, optically stimulated DA release increasingly exceeded that of electrical stimulation. Furthermore, electrical stimulation produced inhibition of DA release across longer duration stimulations. The GABAB antagonist, CGP 55845, increased electrically stimulated DA release significantly more than light stimulated release. The nicotinic acetylcholine receptor antagonist, dihydro-β-erythroidine hydrobromide, inhibited single pulse electrically stimulated DA release while having no effect on optically stimulated DA release. Our results demonstrate that electrical stimulation introduces local multi-synaptic modulation of DA release that is absent with optogenetically targeted stimulation. PMID:26011081

To evaluate the prevalence of health-related behaviors according to presence and type of depression in Brazilian adults. Based on a sample of 49,025 adults (18 to 59 years) from the National Survey on Health 2013 (PNS 2013), we estimated the prevalence of health-related behaviors (smoking; passive smoking; frequent or risky alcohol consumption; leisure time physical activity; time watching TV; and eating pattern indicators), according to the presence of depression (minor and major), evaluated by the Patient Health Questionnaire - 9 (PHQ-9), and the report of depressive mood (in up to seven days or more than seven days) over a two-week period. Prevalence ratios were estimated by Poisson regression. Evaluated by the PHQ-9 scale, 9.7% of the Brazilian adults had depression and 3.9% presented major depression. About 21.0% reported depressive mood and, in 34.9% of them, that feeling has been present for more than seven days. In individuals with major depression (PHQ-9), higher prevalence was found in almost all unhealthy behaviors analyzed, in particular, smoking (PR = 1.65), passive smoking (PR = 1.55), risk alcohol consumption (PR = 1.72), TV for ≥ 5 hours/day (PR = 2.13), consumption of fat meat (PR = 1.43) and soft drink (PR = 1.42). The prevalence ratios tended to be lower in those with minor depression. Similar results were observed in adults with depressive mood. This study detected relevant association between depression and health behaviors, in particular for smoking and physical activity. The associations found with the PHQ were similar to those observed with the application of a single question about depressive mood. Our results indicate the importance of assessing the presence of depression and the frequency and severity of symptoms when implementing actions for the promotion of healthy behaviors. Avaliar a prevalência de comportamentos relacionados à saúde segundo a presença e tipo de depressão em adultos brasileiros. Com base em amostra de 49.025 adultos (18 a 59 anos) da Pesquisa Nacional de Saúde 2013, foram estimadas as prevalências de comportamentos relacionados à saúde (tabagismo, fumo passivo, consumo frequente ou de risco de álcool, atividade física de lazer, horas de TV e indicadores de padrão alimentar), segundo a presença de depressão (menor e maior), avaliada pela escala PHQ-9, e o relato de humor depressivo (em até sete dias ou em mais de sete dias) em um período de duas semanas. Razões de prevalências foram estimadas por meio de regressão de Poisson. Avaliados pela escala PHQ-9, 9,7% dos adultos brasileiros apresentaram depressão, e 3,9%, depressão maior. Cerca de 21,0% relataram humor depressivo e em 34,9% deles esse sentimento esteve presente por mais de sete dias. Nos indivíduos com depressão maior (PHQ-9), foram constatadas prevalências mais elevadas de quase todos os comportamentos não saudáveis analisados, principalmente tabagismo (RP = 1,65), fumo passivo (RP = 1,55), consumo de risco de álcool (RP = 1,72), horas de TV ≥ 5 h/dia (RP = 2,13), consumo de carne gordurosa (RP = 1,43) e refrigerante (RP = 1,42). As razões de prevalência tenderam a ser menores na depressão menor. Resultados similares foram observados nos adultos com humor depressivo. O estudo detectou relevante associação entre depressão e comportamentos de saúde, em especial, para tabagismo e atividade física. As associações encontradas com o uso do PHQ foram similares às observadas com a aplicação de uma única pergunta sobre humor depressivo. Os resultados do estudo sinalizam a importância da avaliação da presença de depressão e da frequência e gravidade dos sintomas quando da implementação de ações para a promoção de comportamentos saudáveis.

Several factors that act maternally to regulate seed size have been identified, such as AUXIN RESPONSE FACTOR2, APETALA2, KLUH, and DA1, but the genetic and molecular mechanisms of these factors in seed size control are almost totally unknown. We previously demonstrated that the ubiquitin receptor DA1 acts synergistically with the E3 ubiquitin ligase ENHANCER1 OF DA1 (EOD1)/BIG BROTHER to regulate the final size of seeds in Arabidopsis thaliana. Here, we describe another RING-type protein with E3 ubiquitin ligase activity, encoded by DA2, which regulates seed size by restricting cell proliferation in the maternal integuments of developing seeds. The da2-1 mutant forms large seeds, while overexpression of DA2 decreases seed size of wild-type plants. Overexpression of rice (Oryza sativa) GRAIN WIDTH AND WEIGHT2, a homolog of DA2, restricts seed growth in Arabidopsis. Genetic analyses show that DA2 functions synergistically with DA1 to regulate seed size, but does so independently of EOD1. Further results reveal that DA2 interacts physically with DA1 in vitro and in vivo. Therefore, our findings define the genetic and molecular mechanisms of three ubiquitin-related proteins DA1, DA2, and EOD1 in seed size control and indicate that they are promising targets for crop improvement.

The changes in pharmacokinetics of DA-8159 by omeprazole with respect to inhibition of CYP3A1/2 in rats were evaluated. After oral administration of DA-8159 at dose of 30 mg/kg to rats pretreated with oral omeprazole at 30 mg/kg for 1 week, the total area under the plasma concentration-time curve from time zero to time infinity (AUC) of DA-8159 was significantly greater (37.5% increase) than that in control rats. This could be due to inhibition of metabolism of DA-8159 by inhibition of CYP3A1/2 by omeprazole. The AUC(DA-8164 (a metabolite of DA-8159))/AUC(DA-8159) ratio was also smaller (32.4% decrease) with omeprazole. After oral administration of DA-8159 at a dose of 30 mg/kg to rats without or with cola beverage, the pharmacokinetic parameters of DA-8159 and DA-8164 were not significantly different between two groups of rats. This suggested that cola beverage did not have any considerable effects on CYP3A1/2 in rats.

Radiation degraded κ-carrageenan (1% solution at absorbed doses of 20 kGy and 30 kGy) were tested for its plant growth promoter (PGP) effect on pechay plants under hydroponics condition. Results revealed that higher PGP effects were found in κ-carrageenan irradiated at an absorbed dose of 30 kGy. Mw of irradiated κ-carrageenan as measured by GPC were determined to be 7362 Da and 6762 Da for 20 kGy and 30 kGy, respectively. Fractionation of the irradiated κ-carrageenan (30 kGy) was done to separate different Mw fractions using Mw cut-off filters of 1 kDa, 3 kDa, and 5 kDa. The PGP effect of the different retentates showed that biological activity in plants followed the order of 5 kDa>3 kDa>1 kDa using hydroponics condition but the reverse was observed in the order of 1 kDa>3 kDa>5 kDa when absorbed in plants by foliar spraying. GPC chromatogram indicated at least three (3) low molecular weight (LMW) fragments from radiation modified κ-carrageenan solution with an Mw<2000 Da. A fragment has also been identified with an Mw of as low as 160 Da which was produced under acidic (un-neutralized) condition. This may be attributed to the formation of 5-hydroxymethylfurfural (5-HMF).

Dopamine (DA) released from lateral olivocochlear (LOC) terminals may have a neuroprotective effect in the cochlea. To explore the role of N-methyl-d-aspartate (NMDA) receptors and nitric oxide (NO) in the modulation of a cochlear DA release, we measured the release of [3H]DA from isolated mouse cochlea in response to the application of NMDA. NMDA at 100 muM significantly increased the electrical-field stimulation-evoked and resting release of DA from the cochlea. The NO donor sodium nitroprusside enhanced the basal outflow of DA but failed to influence the evoked release. The administration of the nitric oxide synthase inhibitor N omega-nitro-L-arginine methyl ester (L-NAME) alone was ineffective, but it significantly inhibited the initial phase of the NMDA-induced elevation of DA outflow, which suggested the role of NO in the NMDA-induced DA release. The DA uptake inhibitor nomifensine increased the electrically evoked release of DA. Nomifensine failed to change the effect of NMDA on the resting or electrically-evoked DA release, which suggested that the uptake mechanism does not play a role in NMDA-evoked and NO-mediated DA release. In summary, we provide evidence that NO can modulate the release of DA from the cochlea following NMDA receptor activation, but does not affect the uptake of DA.

Dystrophic axons (DA) represent a major pathological feature of several neurodegenerative disorders, including infantile neuroaxonal dystrophy (INAD) and Alzheimer disease. We have previously presented evidence that amyloid beta precursor protein (BPP) and ubiquitin (Ub) are present in DA of different origin. We have now characterized the immunoreactivity of DA experimentally induced in rat by the administration of parabromophenylacetylurea (BPAU) and examined the subcellular localization of Ub and BPP in BPAU-induced DA and in DA present in subjects affected by INAD. BPAU-induced DA strongly immunoreacted with antisera to Ub and to COOH- and NH2-terminal regions of BPP. Immunoblots of DA-enriched brain regions were consistent with an increase in the amount of Ub and BPP in DA. Moreover, BPAU-induced DA immunoreacted with antibodies to PGP 9.5, a neuronal-specific Ub COOH-terminal hydrolase, and to the inducible heat shock protein 70. Antigenic characterization also indicated that the tubulovesicular membranes within DA derived largely from the smooth endoplasmic reticulum rather than from the Golgi system or the synaptic vesicles. Subcellular immunolocalization of Ub and BPP in both INAD- and BPAU-induced DA revealed that Ub and BPP colocalize in granulovesicular material in both conditions. In INAD DA intense Ub immunoreactivity was also detected in nonmembranous electron dense structures that were present only in these DA, probably because of the chronic course of INAD. Although BPP immunostaining may be related to accumulation of BPP-containing membranes in DA, Ub immunostaining is likely to result from activation of the Ub system by the neuron in the attempt to remove excessive and possibly abnormal proteins. A similar pathogenesis can be postulated for DA of Alzheimer disease. Images Figure 1 Figure 2 Figure 3 Figure 4 PMID:7512790

Da-jiang is a typical traditional fermented soybean product in China. At present, the proteins in da-jiang are needed to be explored. The composition and species of microbial proteins in traditional fermented da-jiang were analyzed by metaproteomics based on sodium dodecyl sulfonate-polyacrylamide gel electrophoresis (SDS-PAGE) and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). The results showed that the number and variety of microbial proteins in the traditional fermented da-jiang from different regions were different. The production site influences the fermentation in da-jiang. Then we analyzed the functions of the microbial proteins identified in da-jiang, and found that they were mainly involved in the process of protein synthesis, glycometabolism and nucleic acid synthesis. In addtion, we compared the proteins composition in different da-jiang. There are 51 common proteins of naturally fermented da-jiang, and 25 common microbial sources. The main commonly microbial sources of fungal proteins are Saccharomyces cerevisiae and Schizosaccharomyces; the main commonly microbial sources of bacterial proteins are Enterococcus faecalis, Leuconostoc mesenteroides, Acinetobacter baumannii, and Bacillus subtilis. These common microbes play the predominant role in da-jiang fermentation. The present results help us to understand the fermentation of da-jiang and improve the quality and safety of final products in the future. The study illustrated metaproteome of microbiota in traditional fermented soybean paste, da-jiang, by sodium dodecyl sulfonate-polyacrylamide gel electrophoresis (SDS-PAGE) and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS). A method of extracting metaproteome from microbiota in da-jiang was attempted. The findings help to understand the fermentation of da-jiang and improve the quality and safety of da-jiang in fermented industry. © 2018 Institute of Food Technologists®.

The Weighing Chair of Sanctorius Sanctorius: A Replica.

PubMed

Hollerbach, Teresa

2018-05-14

In 1614, the physician Sanctorius Sanctorius (1561-1636) published his most famous work entitled Ars […] de statica medicina (On static medicine). This is a work composed of aphorisms that present the practical results of a series of weighing procedures, rather than theoretical observations. De statica medicina is the result of a large number of test series that Sanctorius carried out over many years with the weighing chair he constructed himself in order to quantify the so-called perspiratio insensibilis, an insensible perspiration of the human body. Through his weighing experiments, Sanctorius introduced the idea of quantitative research into physiology. Although historical accounts ascribe an important role to Sanctorius as the founder of a new medical science, up until now the design of his weighing chair and the method of measurement have not been closely analysed. The aim of this paper is to close this gap. Through a collaboration between the Max Planck Institute for the History of Science and the Technical University of Berlin (Institute of Vocational Education and Work Studies), Sanctorius's weighing chair was reconstructed and experiments carried out with it. This opened new perspectives on Sanctorius's work and led to a reconsideration of the function and purpose of his weighing chair. With his static medicine, Sanctorius repurposed an old instrument. The replication of the weighing chair and the repetition of the experiments demonstrate that this novel application of scales posed some challenges for the mechanical design of the instrument. We recognized that the instrument fulfilled different functions that might in turn have affected its design, precision, and the measuring method applied. Although in the end we could not clarify how Sanctorius actually conducted his measurements, we were nevertheless able to develop an understanding of Sanctorius's mechanical and practical knowledge that would not have been possible for us to develop solely on the basis of the written sources.

In Spain, according to the Di@bet.es study, 13.8% of the adult population suffers from diabetes and 14.8% from some form of prediabetes (impaired glucose tolerance, impaired fasting glucose or both). Since early detection of prediabetes can facilitate the implementation of therapeutic measures to prevent its progression to diabetes, we believe that preventive strategies in primary care and specialized clinical settings should be agreed. Screening for diabetes and prediabetes using a specific questionnaire (FINDRISC) and/or the measurement of fasting plasma glucose in high risk patients leads to detecting patients at risk of developing diabetes and it is necessary to consider how they should be managed. The intervention in lifestyle can reduce the progression to diabetes and reverse a prediabetic state to normal and is a cost-effective intervention. Some drugs, such as metformin, have also been shown effective in reducing the progression to diabetes but are not superior to non-pharmacological interventions.

Benign prostatic hyperplasia (BPH) is a high prevalence condition in men over 50 years that requires continued assistance between primary care and urology. Therefore, consensus around common referral criteria was needed to guide and support both levels. Medical history, symptom assessment with International Prostate Symptom Score (IPSS) questionnaire, digital rectal examination and prostate-specific antigen (PSA) measurement are diagnostic tests available for general practitioners that allow setting a correct BPH diagnose. Patients with an IPSS<8 should be monitored by evaluating them annually. Treatment with alpha-blockers and an evaluation at the first and third month is recommended in patients with an IPSS 8-20 and if the prostate is small, if the prostate size is large treatment with alpha-blockers or 5alpha-reductase inhibitors and evaluation at the third and six month is recommended, and in patients with a large prostate and a PSA >1.5 ng/ ml combined treatment and evaluation at the first and sixth month is recommended. Some clear criteria for referral to urology are established in this document, which help in the management of these patients. Those patients with BPH who do not show any improvement at the third month of treatment with alpha-blockers, or the sixth month with 5alpha-reductase inhibitors, will be referred to urology. Patients will also be referred to urology if they have lower urinary tract symptoms, a pathological finding during rectal examination, IPSS>20, PSA>10 ng/ml or PSA>4 ng/ml and free PSA<20% or if they are <50 years with suspected BHP, or if they have any urological complication.

Gravity-dependent signal path variation in a large VLBI telescope modelled with a combination of surveying methods

The very long baseline interferometry (VLBI) antenna in Medicina (Italy) is a 32-m AZ-EL mount that was surveyed several times, adopting an indirect method, for the purpose of estimating the eccentricity vector between the co-located VLBI and Global Positioning System instruments. In order to fulfill this task, targets were located in different parts of the telescope’s structure. Triangulation and trilateration on the targets highlight a consistent amount of deformation that biases the estimate of the instrument’s reference point up to 1 cm, depending on the targets’ locations. Therefore, whenever the estimation of accurate local ties is needed, it is critical to take into consideration the action of gravity on the structure. Furthermore, deformations induced by gravity on VLBI telescopes may modify the length of the path travelled by the incoming radio signal to a non-negligible extent. As a consequence, differently from what it is usually assumed, the relative distance of the feed horn’s phase centre with respect to the elevation axis may vary, depending on the telescope’s pointing elevation. The Medicina telescope’s signal path variation Δ L increases by a magnitude of approximately 2 cm, as the pointing elevation changes from horizon to zenith; it is described by an elevation-dependent second-order polynomial function computed as, according to Clark and Thomsen (Techical report, 100696, NASA, Greenbelt, 1988), a linear combination of three terms: receiver displacement Δ R, primary reflector’s vertex displacement Δ V and focal length variations Δ F. Δ L was investigated with a combination of terrestrial triangulation and trilateration, laser scanning and a finite element model of the antenna. The antenna gain (or auto-focus curve) Δ G is routinely determined through astronomical observations. A surprisingly accurate reproduction of Δ G can be obtained with a combination of Δ V, Δ F and Δ R.

Aims: We aim to validate the Einstein equivalence principle (local position invariance) by limiting the fractional changes in the electron-to-proton mass ratio, μ = me/mp, measured in Galactic plane objects. Methods: High-resolution spectral observations of dark clouds in the inversion line of NH3(1, 1) and pure rotational lines of other molecules (the so-called ammonia method) were performed at the Medicina 32-m and the Effelsberg 100-m radio telescopes to measure the radial velocity offsets, ΔRV = Vrot - Vinv, between the rotational and inversion transitions, which have different sensitivities to the value of μ. Results: In our previous observations (2008-2010), a mean offset of ⟨ΔRV⟩ = 0.027 ± 0.010 km s-1 (3σ confidence level (C.L.)) was measured. To test for possible hidden errors, we carried out additional observations of a sample of molecular cores in 2010-2013. As a result, a systematic error with an amplitude ~0.02 km s-1 in the radial velocities was revealed. The averaged offset between the radial velocities of the rotational transitions of HC3N(2-1), HC5N(9-8), HC7N(16-15), HC7N(21-20), and HC7N(23-22), and the inversion transition of NH3(1, 1) is ⟨ΔRV⟩ = 0.003 ± 0.018 km s-1 (3σ C.L.). This value, when interpreted in terms of Δμ/μ = (μobs - μlab)/μlab, constraints the μ-variation at the level of Δμ/μ < 2 × 10-8 (3σ C.L.), which is the most stringent limit on the fractional changes in μ based on astronomical observations. Based on observations obtained with the Effelsberg 100-m telescope operated by the Max-Planck Institut für Radioastronomie on behalf of the Max-Planck-Gesellschaft (Germany), and with the Medicina 32-m telescope operated by INAF (Italy).

Parkinson’s disease is characterized by the loss of dopamine (DA) neurons in the substantia nigra pars compacta (SNc). DA neurons in the ventral tegmental area are more resistant to this degeneration than those in the SNc, though the mechanisms for selective resistance or vulnerability remain poorly understood. A key to elucidating these processes may lie within the subset of DA neurons that corelease glutamate and express the vesicular glutamate transporter VGLUT2. Here, we addressed the potential relationship between VGLUT expression and DA neuronal vulnerability by overexpressing VGLUT in DA neurons of flies and mice. In Drosophila, VGLUT overexpression led to loss of select DA neuron populations. Similarly, expression of VGLUT2 specifically in murine SNc DA neurons led to neuronal loss and Parkinsonian behaviors. Other neuronal cell types showed no such sensitivity, suggesting that DA neurons are distinctively vulnerable to VGLUT2 expression. Additionally, most DA neurons expressed VGLUT2 during development, and coexpression of VGLUT2 with DA markers increased following injury in the adult. Finally, conditional deletion of VGLUT2 made DA neurons more susceptible to Parkinsonian neurotoxins. These data suggest that the balance of VGLUT2 expression is a crucial determinant of DA neuron survival. Ultimately, manipulation of this VGLUT2-dependent process may represent an avenue for therapeutic development. PMID:29337309

MK-801 protection against methamphetamine-induced striatal dopamine terminal injury is associated with attenuated dopamine overflow.

Repeated administrations of methamphetamine (m-AMPH) produce high extracellular levels of dopamine (DA) and subsequent striatal DA terminal damage. Pharmacological blockade of N-methyl-D-aspartate (NMDA) receptors has been shown previously to prevent m-AMPH-induced striatal DA terminal injury, but the mechanism for this protection is unclear. In the present study, in vivo microdialysis was used to determine the effects of blockade of NMDA receptors with the noncompetitive antagonist MK-801 on m-AMPH-induced striatal DA overflow. Four injections of MK-801 (0.5 mg/kg, ip) alone did not significantly change extracellular striatal DA concentrations from pretreatment values. Four treatments with m-AMPH (4.0 mg/kg, sc at 2-hr intervals) increased striatal DA overflow, and the overflow was particularly extensive following the fourth injection. This m-AMPH regimen produced a 40% reduction in striatal DA tissue content 1 week later. Treatment with MK-801 15 min before each of the four m-AMPH injections or prior to only the last two m-AMPH administrations attenuated the m-AMPH-induced increase in striatal DA overflow and protected completely against striatal DA depletions. Other MK-801 treatment regimens less effectively reduced the m-AMPH-induced striatal DA efflux and were ineffective in protecting against striatal DA depletions. Linear regression analysis indicated that cumulative DA overflow was strongly predictive (r = -.68) of striatal DA tissue levels measured one week later. These findings suggest that the extensive DA overflow seen during a neurotoxic regimen of m-AMPH is a crucial component of the subsequent neurotoxicity.(ABSTRACT TRUNCATED AT 250 WORDS)
