    Full Text Available OBJETIVO: Determinar a freqüência global de artefatos na seqüência "gradient and spin echo" (GRASE, por tipo e grau do artefato, em exames de ressonância magnética de abdome; realizar comparação entre as seqüências GRASE e duas seqüências TSE previamente selecionadas como aquelas com melhor relação sinal-ruído e menor incidência de artefatos. MATERIAIS E MÉTODOS: Foi realizado estudo prospectivo, autopareado, em 86 pacientes submetidos a ressonância magnética de abdome superior, sendo adquiridas a seqüência GRASE com sincronizador respiratório e supressão de gordura e seis seqüências TSE ponderadas em T2. Dentre as seis seqüências TSE, foram previamente selecionadas aquelas com melhor relação sinal-ruído e menor número de artefatos, que foram as realizadas com supressão de gordura e com sincronizador respiratório, sendo uma com bobina de corpo (seqüência 1 e outra com bobina de sinergia (seqüência 2. A análise das imagens foi realizada por dois observadores em consenso, quanto a presença, grau e tipo de artefato. Posteriormente os dados foram analisados estatisticamente, através do teste de Friedman e do qui-quadrado. RESULTADOS: A freqüência absoluta de artefatos nas seqüências utilizadas foi de 65,02%. Os artefatos mais encontrados nas três seqüências estudadas foram os de respiração (30% e de pulsação (33%. Apenas 3% dos casos apresentaram algum tipo de artefato que dificultava a análise das imagens. As freqüências de artefatos nas diversas seqüências foram: GRASE, 67,2%; seqüência TSE 1, 62,2%; seqüência TSE 2, 65,5%. Não houve diferença estatisticamente significante na freqüência de artefatos encontrados nas seqüências GRASE e nas seqüências TSE (p = 0,845; NS. CONCLUSÃO: As seqüências GRASE e TSE ponderadas em T2 com sincronizador respiratório e com supressão de gordura, independentemente da bobina utilizada, apresentam freqüentemente artefatos, porém com incid

    Full Text Available A mamografia, na atualidade, é o método mais efetivo de diagnóstico precoce do câncer de mama. Um exame com alto padrão de qualidade pode visualizar, em 85% a 90% dos casos, um tumor com mais de dois anos de antecedência de ocorrer acometimento ganglionar, em mulheres com mais de 50 anos de idade. A diferença radiográfica entre o tecido normal e o doente é extremamente tênue, logo, a alta qualidade do exame é indispensável para alcançar resolução de alto contraste que permita essa diferenciação. Para alcançar alto padrão é imperativo que o exame mamográfico siga protocolos rígidos e pré-estabelecidos. Os artefatos são defeitos no processamento do filme que comprometem o resultado final da imagem, podendo resultar em informações perdidas ou mascaradas. Há numerosos tipos de artefatos derivados de diversas fontes na aquisição da imagem, como o processador, o desempenho do técnico de radiologia, o mamógrafo ou o paciente, todos resultando na degradação da imagem obtida. O presente artigo tem o objetivo de revisar métodos eficazes no controle de qualidade do exame mamográfico e analisar os artefatos mais importantes na prática diária, com ilustrações e dicas de como evitá-los.Currently, mammography is the most effective method for an early diagnosis of breast cancer. In 85% to 90% of the cases, a high quality mammography allows the visualization of a tumor more than two years before the occurrence of lymph nodes involvement in women over 50 years of age. The radiological appearance of a normal and a sick tissue is very similar, therefore, a high quality of the scan is essential to obtain high contrast resolution to allow distinguishing them. Strict and preestablished protocols must be followed during mammography in order to reach high quality standards. Artifacts are defects occurred during film processing that interfere in the quality of the final image and can result in loss or masked information. Several

    Full Text Available No estuário amazônico, a palmeira Mauritia flexuosa L. f. (miriti é conhecida por fornecer matéria-prima para a confecção de cestaria e brinquedos, ambos de relevância econômica e cultural para a população local. Este estudo teve como objetivo realizar um levantamento a respeito da produção e comercialização dos dois principais artefatos - paneiros e brinquedos de miriti, no município de Abaetetuba, Pará. A pesquisa foi conduzida na comunidade ribeirinha de Cutininga e em duas associações de artesãos da sede municipal, por meio de entrevistas semiestruturadas e não estruturadas, envolvendo 18 informantes. Entre os produtos cesteiros comercializados, o paneiro é o único que conseguiu se manter no mercado e atualmente é a principal fonte de renda para os moradores da comunidade de Cutininga. Já a comercialização dos brinquedos de miriti vem ganhando maior expressividade a cada ano, com ápice de produção em outubro, durante a festividade do Círio de Nossa Senhora de Nazaré. Tanto os brinquedos como os paneiros atingiram escala comercial, sendo que o brinquedo é o produto feito da folha de Mauritia flexuosa L. f. de maior representatividade econômica no município. Porém, na região das ilhas, onde está situada Cutininga, constatou-se que o paneiro apresenta maior importância econômica.

    Full Text Available Fundamento: Há poucos dados sobre a definição de parâmetros simples e robustos para predizer artefato de imagem em tomografia computadorizada (TC cardíaca. Objetivos: Avaliar o valor da simples medida da espessura do tecido subcutâneo (espessura pele-esterno como preditor de artefato de imagem em TC cardíaca. Métodos: O estudo avaliou 86 pacientes submetidos a angiotomografia computadorizada cardíaca (ATCC com sincronização prospectiva com ECG e avaliação de escore de cálcio coronário com 120 kV e 150 mA. A qualidade da imagem foi medida objetivamente pelo artefato de imagem na aorta em ATCC, sendo 'artefato baixo' definido como aquele < 30 UH. Os diâmetros torácicos anteroposterior e laterolateral, o artefato de imagem na aorta e a espessura pele-esterno foram medidos como preditores de artefato em ATCC. A associação de preditores e artefato de imagem foi avaliada usando-se correlação de Pearson. Resultados: A dose média de radiação foi 3,5 ± 1,5 mSv. O artefato de imagem médio na ATCC foi de 36,3 ± 8,5 UH, sendo o artefato de imagem médiona fase sem contraste do exame de 17,7 ± 4,4 UH. Todos os preditores foram independentemente associados com artefato em ATCC. Os melhores preditores foram espessura pele-esterno, com correlação de 0,70 (p < 0,001, e artefato de imagem na fases em contraste,com correlação de 0,73 (p < 0,001. Ao avaliar a habilidade de predizer artefato de imagem baixo, as áreas sob a curva ROC para o artefato de imagem na fases em contraste e para a espessura pele-esterno foram 0,837e 0,864, respectivamente. Conclusão: Tanto espessura pele-esterno quanto artefato de escore de cálcio são preditores simples e precisos de artefato de imagem em ATCC. Tais parâmetros podem ser incorporados aos protocolos de TC padrão para ajustar adequadamente a exposição à radiação.

    Full Text Available Introdução: o LaTeX é um programa para criação e edição de documentos que requerem alta qualidade tipográfica mas, por apresentar características complexas, exige a criação de templates que facilitem sua utilização. O objetivo deste artigo consistiu em criar e avaliar um modelo de teses e dissertações em LaTeX para o Programa de Pós-Graduação em Engenharia de Produção da Universidade Paulista, facilitando a inclusão dos discentes e permitindo a apresentação de trabalhos dentro dos padrões internacionais. Método: adotou-se a metodologia do Design Science Research (DSR, que consiste em fornecer diretrizes para criação ou adaptação e avaliação de artefatos, tais como software e outras ferramentas científicas. Como base para os requisitos utilizou-se o manual de normas acadêmicas disponível no site da instituição. As avaliações ocorreram por meio de simulações e apresentação para discentes e docentes do programa com posterior aplicação de um questionário para 34 respondentes. Resultados: verificou-se que cerca de 40% já conhecia o programa e 60% não o conhecia. Após a apresentação deste, aproximadamente 32% considerou a utilização difícil, enquanto 50% a consideraram razoável e 18% fácil. Cerca de 76.5% dos grupos formados para análise apontou positivamente a condição de substituir os editores convencionais pelo LaTeX, sendo que 23.5% discordaram. As variáveis “pró utilização” mais destacadas foram: qualidade tipográfica, concentração no conteúdo lógico e facilidades. Os mestrandos apresentaram maior homogeneidade nas respostas. Conclusão: o template proposto foi aceito com entusiasmo, ainda que com a ressalva de se realizarem treinamentos devido à uma percepção significativa sobre a dificuldade de utilização.

Em nossas discussões, compreendemos que esse artefato constitui-se em uma pedagogia cultural que produz e divulga significados acerca da temática sexualidade, operando não apenas como fonte de informação ou entretenimento. Esse artefato, além de possibilitar a discussão de questões como sistemas genitais, métodos contraceptivos, Aids e DST, que já estão presentes nos currículos escolares e nos Parâmetros Curriculares Nacionais (PCN, promove a inclusão de temas acerca de anseios, medos, prazeres, comportamento, gênero e corpo que nem sempre são abordados nos currículos, problematizando, assim, diferentes representações e significados atribuídos à sexualidade e que circulam em nossa sociedade.

    Full Text Available Estudo avaliativo de abordagem quantitativa, com amostra de 104 gestantes, com o objetivo de comparar os achados de infecções vaginais em gestantes obtidos por meio do fluxograma de corrimento vaginal com exames presentes na prática clínica da Enfermagem. Os dados foram coletados por meio de entrevista e exame ginecológico realizados de janeiro a julho de 2011. O fluxograma não se mostrou eficaz na identificação de candidíase e tricomoníase, apresentou baixa sensibilidade (0,0%; 50% e valor preditivo positivo (0,0%; 3,6% para as duas infecções e baixa especificidade para tricomoníase (46%. Mostrou-se satisfatório para vaginose bacteriana, com alta sensibilidade (100%, valor preditivo negativo (100% e acurácia (74%. Conclui-se que o emprego do fluxograma precisa ser reavaliado, visto que não foi eficaz em identificar infecções importantes em gestantes. Os esforços para o desenvolvimento de testes eficazes devem ser contínuos, com intuito de prevenir a disseminação de infecções e reduzir tratamentos desnecessários.

    The objective of this paper is to estimate the values of doses, which are absorbed dose to the lens and thyroid in a dental X-ray. Thermoluminescence dosimeters were used, once they provide a reading of quality and effectiveness. This study was based on dental exams conducted in patients in order to estimate the dose that disperses to the lens of the eye and for the thyroid during an intraoral exam. Data collection took place in two institutions, one governmental, which had the device SELETRONIC 70X and other particular. This study showed that there is a considerable variation between the appliances. Using the appliance DABI 1070, there was a greater absorption of radiation in the right eye (values greater than 5 mGy) and a lower dose in the thyroid, and the Seletronic 70X presented an incidence of higher dose deposited in the skin and in other points there was a balance in the values. In the appliance SELETRONIC 70X, there was again a greater absorption of radiation in the right eye and a lower setting in the thyroid. The excessive dose, besides does not favor at all for the quality of radiograph, represents a risk for the patient who absorbs unnecessary and harmful radiation to the body.

    Introduction: In occupational medicine, medical care must be geared toward the prevention of worker health. However, occupational medical exams often seek only through rigorous screening, reduce absenteeism, and thus increase productivity. To meet this goal, many institutions include radiological examinations indiscriminately in their medical and expert evaluations, contrary to the principle of justification. Objective: To provide a reflection about the presence of radiological exams in occupational medical evaluations. Methodology: Literary review including legislation related to the research topic. Results: Portaria 453/98 ANVISA prohibits the performance of radiological examinations for employment or expert purposes, except in cases where the exam may bring a benefit to the health of the individual examined or to society. However, in some situations the Norma Regulamentadora number 7 of the Ministry of Labor and Employment provides for radiological exams as a parameter for monitoring occupational exposure. Article 168 of the Consolidation of Labor Laws also prescribes that additional examinations may be required, at the medical discretion, to determine the physical and mental fitness of the employee for the job. Conclusion: Although there are legal provisions that prohibit and others that allow radiological exams in medical occupational evaluations, companies and institutions should take into account that any radiological exam has a risk involved and should not request them in a compulsory and indiscriminate manner. Radiological exams are only permissible to elucidate the diagnostic hypothesis produced by clinical evaluation, in order to provide a real benefit for the individual.

    Full Text Available INTRODUÇÃO: Para que radiografias ofereçam mais benefícios do que riscos, precisam ser realizadas ou solicitadas de acordo com cada situação clínica.OBJETIVO: Avaliar os exames radiográficos solicitados no atendimento inicial em uma Faculdade de Odontologia, considerando os sinais/sintomas e o motivo para busca pelo atendimento.MATERIAL E MÉTODO: Foram avaliados os prontuários de 3.100 pacientes adultos, tratados em um período de três anos, excluindo aqueles em que os pacientes não haviam realizado exames radiográficos na consulta inicial. Numa amostra final de 1.567 prontuários, foram coletados os seguintes dados: idade e gênero, razão da procura pelo tratamento, presença de sinais e/ou sintomas, além da técnica e do número de radiografias realizadas. Os dados foram analisados por estatística descritiva.RESULTADO: 5.034 radiografias realizadas, com média de 3,24 (±2,97 por paciente. Entre as técnicas, a mais utilizada foi a periapical seguida pela panorâmica. Extração dentária e dor foram as razões mais prevalentes da procura pelo atendimento, enquanto dor, doença periodontal e presença de patologias de tecidos moles foram os sinais/sintomas mais comuns. Verificou-se que 35,41% da amostra não apresentou sinais ou sintomas.CONCLUSÃO: Há uma grande variação na requisição de radiografias no exame inicial, mostrando uma falha na aplicação de critérios de seleção de imagens para diagnóstico, o que pode levar à exposição desnecessária do paciente à radiação X.

    Due to the use of radiopharmaceutical positron-emitting in PET exam and realization of tomography by x-ray transmission in CT examination, an increase of dose with hybrid PET/CT technology is expected. However, differences of doses have been reported in many countries for the same type of procedure. It is expected that the dose is an influent parameter to standardize the protocols of PET/CT. This study aimed to estimate the effective doses and absorbed in 65 patients submitted to oncological Protocol in a nuclear medicine clinic in Rio de Janeiro, considering the risk of induction of cancer from the scan. The CT exam-related doses were estimated with a simulator of PMMA and simulated on the lmPACT resistance, which for program effective dose, were considered the weight factors of the lCRP 103. The PET exam doses were estimated by multiplying the activity administered to the patient with the ICRP dose 80 factors. The radiological risk for cancer incidence were estimated according to the ICRP 103. The results showed that the effective dose from CT exam is responsible for 70% of the effective total in a PET/CT scan. values of effective dose for the PET/CT exam reached average values of up to 25 mSv leading to a risk of 2, 57 x 10{sup -4}. Considering that in staging of oncological diseases at least four tests are performed annually, the total risk comes to 1,03x 10{sup -3}.

    One of the challenges of multidetector computerized tomography is to minimize the risk of ionizing radiation using optimized protocols since higher doses are necessary to obtain high image quality. It was also noted that, due to the geometry in image acquisition using MDCT becomes necessary to estimate dose values consistent with the hypothesis clinically and with the specificities of the tomographic equipment. The aim of this study was to estimate the doses in abdomen exams from the data recorded on the MDCT console and dimensions obtained from DICOM images of patients undergoing different clinical protocols. Were collected, from the image DICOM of 101 exams, values of the dose length product (DLP) provided by Philips Health Care - Brilliance 64 equipment console, in order to relate them with the dose values obtained by means of thermoluminescent dosimeters ( TLD ) of CasSo{sub 4}:Mn placed on the surface of a cylindrical simulator abdomen acrylic manufactured under the technical - operational conditions for a typical abdomen exam. From the data obtained, it was possible to find a factor of 1.16 ( 5 % ) indicating that the DLP values Brilliance 64 console underestimate the doses and this should be used with correction factor to estimate the total dose of the patient.

O critério diagnóstico atual para o DM propõe os seguintes testes laboratoriais: glicose plasmática em jejum, hemoglobina glicada ou glicosilada, teste oral de tolerância à glicose, frutosamina, insulina, peptídeo C e glucagon. Estes exames laboratoriais podem apresentar interferências de medicamentos, sejam fisiológicas ou analíticas. Na literatura consultada foi possível identificar 30 fármacos ou grupo de fármacos que possuem evidências de interferir nos principais exames de diagnóstico da DM. Ressalta-se que praticamente na sua totalidade estes interferem nos níveis de glicemia, sendo que, 81,5% destes contribuem de forma a aumentar estes valores. Dentre estes fármacos encontram-se MIPs (medicamentos isentos de prescrição, como o paracetamol e o ácido acetilsalicílico, e anti-inflamatórios esteroidais, como a dexametasona e prednisolona, amplamente utilizados na terapêutica medicamentosa. Da mesma forma, os medicamentos empregados no tratamento de pacientes diabéticos incluído na RENAME como insulina NPH (protamina neutra Hagedorn, insulina humana regular, glibenclamida, gliclazida e cloridrato de metformina podem interferir em exames laboratoriais. O diagnóstico precoce e o tratamento adequado se fazem necessários a fim de prevenirem maiores danos aos portadores desta doença complexa sub diagnosticada. Neste contexto, as interferências medicamentosas são importantes achados nos exames laboratoriais que avaliam o DM e devem ser reconhecidas pelos profissionais de saúde envolvidos.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A avaliação pré-operatória tem como objetivos diminuir a morbimortalidade do paciente cirúrgico, o custo do atendimento perioperatório e a ansiedade pré-operatória. A partir da avaliação clínica deve-se definir a necessidade de exames complementares e estratégias para reduzir o risco anestésico-cirúrgico. O objetivo deste trabalho foi avaliar o benefício de exames de rotina pré-operatório de pacientes de baixo risco em cirurgias de pequeno e médio porte. MÉTODOS: Trata-se de um estudo descritivo, transversal, com 800 pacientes atendidos no consultório de avaliação pré-anestésica do Hospital Santo Antonio, Salvador, BA. Foram incluídos pacientes de 1 a 45 anos, estado físico ASA I, que seriam submetidos a cirurgias eletivas de pequeno e médio porte. Avaliaram-se alterações no hemograma, coagulograma, eletrocardiograma, RX de tórax, glicemia, função renal e dosagem de sódio e potássio e as eventuais mudanças de conduta que ocorreram decorrentes dessas alterações. RESULTADOS: Dos 800 pacientes avaliados, 97,5% fizeram hemograma, 89% coagulograma, 74,1% eletrocardiograma, 62% RX de tórax, 68% glicemia de jejum, 55,7% dosagens séricas de ureia e creatinina e 10,1% dosagens de sódio e potássio séricos. Desses 700 pacientes, 68 (9,71% apresentaram alteração nos exames pré-operatórios de rotina e apenas 10 (14,7% dos considerados alterados tiveram conduta pré-operatória modificada, ou seja, solicitação de novos exames, interconsulta ou adiamento do procedimento. Nenhuma das cirurgias foi suspensa. CONCLUSÃO: Observou-se que excessivos exames complementares são solicitados no pré-operatório, mesmo em pacientes jovens, de baixo risco cirúrgico, com pouca ou nenhuma interferência na conduta perioperatória. Exames aboratoriais padronizados não são bons instrumentos de screening de doenças, além de gerar gastos elevados e desnecessários.

    In nuclear medicine, workers directly involved in exams are constantly exposed to ionizing radiation. The procedure for administration of the radiopharmaceutical to the patient is one of the most critical times of exposure. In tests of myocardial perfusion scintigraphy (MPS) administration of radiopharmaceutical repeats the steps of rest and cardiac stress. In this study, we used a Geiger -Mueller detector for measuring occupational radiation doses for during the administration of technetium- {sup 99m}- sestamibi in MPS tests. In the evaluation, discriminated the stages of examination and related professional experience time to doses measures at home. It were followed 110 procedures at home (55 conducted by professionals with over 5 years experience and 55 conducted by professionals with less than 1 year of experience) and 55 effort procedures. The results showed that the rest of the procedure time and dose are related to the experience of the worker. More experienced workers were faster (mean: 43 {+-} 16 vs 67 {+-} 25 seconds / procedure), and therefore received lower doses (mean 0.57 {+-} 0.16 versus 0.80 {+-} 0.24 {mu}Sv / procedure), both with statistical significance (p <0.001). In step effort, there were procedures lasting longer (mean: 19 {+-} 2 minutes / procedure), which resulted in higher doses (mean 3.0 {+-} 0.6 {mu}Sv / procedure)

    Full Text Available Several archaeological black earth (ABE sites occur in the Amazon region. They contain fragments of ceramic artifacts, which are very important for the archaeological purpose. In order to improve the archaeological study in the region we carried out a detailed mineralogical and chemical study of the fragments of ceramic artifacts found in the two ABE sites of Cachoeira-Porteira, in the Lower Amazon Region. Their ceramics comprise the following tempers: cauixi, cariapé, sand, sand +feldspars, crushed ceramic and so on and are composed of quartz, clay equivalent material (mainly burned kaolinite, feldspars, hematite, goethite, maghemite, phosphates, anatase, and minerals of Mn and Ba. Cauixi and cariapé, siliceous organic compounds, were found too. The mineralogical composition and the morphology of their grains indicate a saprolite (clayey material rich on quartz derived from fine-grained felsic igneous rocks or sedimentary rocks as source material for ceramic artifacts, where silica-rich components such cauixi, cariapé and/or sand (feldspar and rock fragments were intentionally added to them. The high content of (Al,Fe-phosphates, amorphous to low crystalline, must be product of the contact between the clayey matrix of pottery wall and the hot aqueous solution formed during the daily cooking of animal foods (main source of phosphor. The phosphate crystallization took place during the discharge of the potteries put together with waste of organic material from animal and vegetal origin, and leaving to the formation of the ABE-soil profile.Sítios arqueológicos com Terra Preta, denominados de Terra Preta de Índio ou ainda Terra Preta Arqueológica (TPA são muito freqüentes na Amazônia.

    Full Text Available O presente trabalho teve por objetivo discutir aspectos da fertilidade de garanhões e sua relação com o exame andrológico. Numa primeira análise, 10 garanhões usados em monta natural exclusivamente, tiveram seus índices reprodutivos relacionados a qualidade do seu sêmen. Num segundo grupo, foram considerados 14 garanhões cujos acasalamentos eram, alternadamente, inseminação artificial e/ou monta natural. No terceiro estudo, foram relacionados garanhões específicos, pertencentes aos dois grupos anteriores, sabidamente subférteis em que os índices de fertilidade foram relacionados a características do sêmen ou manejo. Quando os garanhões são submetidos a monta natural dentro de um programa de manejo racional existe uma significativa relação entre qualidade de sêmen e fertilidade (P This paper discuss certain aspects of the fertility in stallions and its relationship to the Breeding Soundness Examination.

    Full Text Available A crescente popularização das atividades de telemedicina em todo o mundo tem exigido de médicos e demais profissionais da saúde novas abordagens em sua prática profissional. No que se refere à telerradiologia, observamos forte tendência à transformação de documentos clínicos - como resultados de exames, que até hoje existiam na forma de filmes impressos e laudos em papel - em documentos eletrônicos, disponibilizados em redes internas de clínicas e hospitais, ou pela internet. Esta tendência torna necessária a divulgação e o esclarecimento de conceitos como a certificação digital, a criptografia de dados na internet, a confiabilidade de sites, o documento eletrônico confiável e a assinatura digital. Os princípios básicos desses conceitos, embora por vezes complexos para os profissionais da saúde, podem ser compreendidos de forma efetiva sem que o leitor tenha de mergulhar de cabeça em labirintos como a matemática da criptografia de chaves assimétricas ou os protocolos de comunicação digital de dados. Neste artigo abordaremos de forma direta e com exemplos práticos os aspectos de segurança e confiabilidade de documentos clínicos eletrônicos baseados na internet, com o objetivo de que os usuários médicos possam interagir de forma informada, segura e bem fundamentada com serviços de telerradiologia.The increasing worldwide popularization of telemedicine activities has demanded a new approach to the professional practice by physicians and other health professionals.

    The aim of this work was to estimate the incident air kerma of lateral (LAT) and anterior-posterior (AP) together with posterior-anterior (PA) projection chest X-ray exams in one of the largest pediatric hospitals in Brazil. Dosimetric results are accompanied with the detailed analysis of patient characteristics and radiographer strategy. The exams of 225 (119 male and 106 female) patients were studied and 389 X-ray exams (200 AP/PA projections and 189 LAT projections) of pediatric patients were acquired. Patient thickness can be restored from age, height or weight with the uncertainty of ∼20-30%. Very slight correlation between the patient dose and thickness was observed with the difference in dose for patients of the same thickness reaching 4 times. By standardization of radiological protocols, it should be possible to keep dose within the intervals 50-100 μGy for LAT projection and 40-80 μGy for AP/PA projection. The dose values are lower than those recommended by major European guidelines to good practice. (author)

O presente estudo apresenta uma análise retrospectiva sobre dois conjuntos de dados de campo, comparando grupos contemporâneos de touros de raças puras taurinas e derivadas de cruzamento com zebuínos. Os resultados indicam que o uso de padrões mais flexíveis resultam em um comportamento semelhante dos distintos grupos raciais, quanto à condição reprodutiva, em contraste com os critérios atuais que classificam de maneira diferente animais de distintos genótipos taurinos puros e seu cruzamento com zebuínos. É enfatizada a importância de estudos sobre os critérios recomendados para a classificação reprodutiva de touros, no sentido de reduzir perdas impostas aos sistemas de produção em decorrência de peculiaridades inerentes a grupos genéticos diferenciados.There is a single set of standard for breeding soundness evaluation in bulls for ali breeds and production systems, resulting in economical losses due to high frequencies of culling in bulls of some genotypes. This study presents an analysis on two sets of field data, comparing contemporary groups of bulls from taurine pure-breds and zebu crossbreeds. The results were indicative that more flexible standards could be useful, avoiding injustified culling of bulls. This fact may be justified by the absence of interaction between breed and reproductive condition. It will be importam to continue the studies on procedures and standards for breeding soundness evaluation in bulls, to reduce losses in the production systems due to peculiarities inherent to the genetic groups.

    Positron Emission Tomography (PET) associated with Computed Tomography (CT) allows the fusion of functional and anatomical images. When compared to other diagnostic techniques, PET-CT subjects patients to higher levels of radiation, because two modalities are used in a single exam. In this study, the doses absorbed in 19 patient organs from the tomographic scan were evaluated. Radiochromic films were correctly positioned in the Alderson anthropomorphic simulator, male version. For evaluation, two whole body scan protocols were compared. For evaluation, two whole body scan protocols were compared. An increase of up to 600% in the absorbed dose in the pituitary was observed when the protocols were compared, with the lowest observed increase of approximately 160% for the liver. It is concluded that the dose from CT in patients submitted to PET-CT scanning is higher in the protocol used for diagnosis. Considering the high cost of PET-CT exam, in many cases it is preferable that the CT examination is of diagnostic quality, and not only for anatomical mapping, an argument based on the Principle of Justification.

    Elbow dysplasia disease includes an united anconeal process, fragmented medial coronoid process, osteochondrosis of humeral trochlea, articular incongruity and degenerative joint disease. The aim of this study was to present detailed morphologic and morphometric aspects of the elbow joint in dog in clinical and correlate with radiographic and tomographic (CT) exam. Inter-observer variation for articular incongruity measurements by CT, comparative analysis in the radiographic exam, angle in ulnar notch and its comparative analysis between radiographic and tomographic agreement examination in 44 elbow of dogs with different ages were evaluated. The statistics analyses included the kappa coefficient and interclass correlation and Fischer's test and McNemar's test. It was evidenced that individual performance of each radiographic incidence had poor agreement with the tomographic exam, suggesting that the accomplishment of more than two radiograph views are needed. There was no agreement between the three evaluators in the ulnar notch angle at radiographic and tomographic exams. However, there was good/moderate agreement for articular incongruity measurement in the sagittal plane between evaluators. It was possible to conclude that none of the five radiographic incidences was better than the others for radiographic analysis because each incidence had a better identification of a particular elbow compartment; measurements at the tomographic exam to evaluate radioulnar incongruity had no reproductiveness in the frontal plane, but in sagittal plan had a good/moderate agreement between observers and the angle in ulnar notch presented no repeatability at radiographic exam and no reproductiveness at tomographic exam.

    Full Text Available Tem sido objeto de preocupação da literatura médica e, mais recentemente, da psicológica, a alta prevalência do câncer de mama nas mulheres. O diagnóstico precoce muito favorece na redução dos índices e, entre os meios de detecção, o "auto-exame da mama" se caracteriza como uma prevenção secundária, sem custos e segura. Pesquisas demonstram, contudo, que a prática do auto-exame da mama é insatisfatória, principalmente em mulheres de escolaridade e nível sócio-econômico baixos. Segundo a Teoria da Ação Racional (TRA, a maioria dos comportamentos humanos pode ser explicada em termos de crenças comportamentais ou normativas. Nesse sentido, a presente pesquisa teve por objetivo investigar as crenças modais salientes desse estrato populacional, desprovido de informações claras e serviços de saúde efetivos, através de um levantamento em uma amostra de 40 mulheres entrevistadas em ambulatórios públicos de João Pessoa (PB. As entrevistas continham itens sobre as vantagens e desvantagens do auto-exame da mama, conhecimentos e dados sócio-demográficos. A média de idade da amostra foi de 32,5 anos (DP = 11,37. As entrevistas indicaram um total de 132 crenças comportamentais, que foram categorizadas em nove dimensões e 166 crenças normativas, categorizadas em quatro dimensões. Estes resultados demonstraram que as crenças influenciam a adesão à prática do auto-exame da mama e servirão de base para que os profissionais que lidam com campanhas públicas de prevenção voltem sua atenção para esses aspectos e abordem conteúdos que promovam não só a prática do auto-exame da mama, mas outras estratégias preventivas nesta significativa população.It has been object of concern to the medical literature and, more recently, to psychology, the high prevalence of breast cancer in women.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: O aumento progressivo nos recursos diagnósticos tem aumentado a qualidade e a quantidade dos exames de laboratório realizados nas Unidades de Terapia Intensiva (UTI. A influência deste aumento sobre a morbidade e mortalidade não está bem definida. O objetivo deste estudo foi avaliar a freqüência da solicitação de exames na UTI do HU e verificar se houve ou não relação entre a quantidade de exames solicitados e a idade dos pacientes, o seu desfecho e a gravidade das doenças. MÉTODO: Coorte prospectiva, com abordagem quantitativa. Foram analisados os exames dos pacientes internados na UTI, dos meses de julho a dezembro, 2005. Foram coletados dados clínicos e demográficos dos pacientes e quantificados diariamente os exames mais freqüentemente solicitados na UTI. Seqüencialmente a média diária de exames foi calculada para todo o período de internação. Para fins de análise os pacientes foram divididos obedecendo três critérios: faixa etária, desfecho de saída da UTI e gravidade. Para a análise estatística foram utilizados os testes Exato de Fisher, Qui-quadrado e ANOVA. RESULTADOS: Foram admitidos 113 pacientes durante o período de estudo. A taxa média foi de 11,5 exames por dia de internação. Estes valores não apresentaram diferença estatística quando comparados entre os pacientes com idade acima ou abaixo de 60 anos, entre os que sobreviveram e os que foram a óbito e entre aqueles que tiveram taxa de óbito estimada em menos que 50% ou mais que 50%. CONCLUSÕES: Os exames solicitados não guardam correlação clínica e prognóstica com sua solicitação. Não houve estatística significativa quando a taxa diária média de exames foi relacionada à idade do paciente, ao desfecho e à gravidade.BACKGROUND AND OBJECTIVES: The progressive increasing diagnostic resources had influenced the quality and quantity of laboratory exams.

    There is little information on developing countries about the use of diagnostic imaging procedures and the doses associated with radiological examinations. This study assessed the pattern and trend of diagnostic imaging usage in outpatients of the Brazilian Unified Health System (SUS) by modality and examined body part. Emphasis was given to computed tomography (CT) scans for which the analysis was extended to the private health care sector and included the evaluation of age at examination distribution, and dose estimation for children and young adults. Information on the use of diagnostic imaging procedures among SUS outpatients was obtained from the Outpatient Information System (SIA) of the Department of Information Technology of SUS (DATASUS). Data on the use of CT in the private health care sector were extracted from the Radiological Information Systems (RIS) of 25 private radiology services in 8 Brazilian cities. Effective doses and absorbed doses on organs of interest were estimated individually for 4,497 patients younger than 20 years of age using CT scan technical parameters and Monte Carlo simulations of radiation transport. Between 2002 and 2012 it was observed that conventional radiology was the most frequent modality of diagnostic imaging in SUS outpatients, but more sophisticated modalities, such as CT and magnetic resonance imaging, had the highest growth rates over the study period. The most frequent CT scan in SUS outpatients between 2001 and 2011 was the head/neck exam, but abdomen/pelvis examinations were the ones that grew the most. Patients up to 20 years of age made approximately 13% and 9% of the CT examinations between 2008 and 2014 in the public and private health care systems, respectively. About one-third of the private-sector patients had more than one CT scan in this period. There was great variation in doses, even for the same type of procedure in patients of the same age group. The highest mean effective dose was 13.5 mSv estimated

    Full Text Available Neste texto, examinamos as condições sociais e semióticas em que a escrita se faz presente no cotidiano de uma turma da educação infantil de uma escola pública em Belo Horizonte, por meio da análise de eventos interacionais e de letramento identificados nesse contexto. Os eventos analisados integram o banco de dados de uma pesquisa que envolveu a observação participante e adotou as abordagens da etnografia interacional e da sociologia da infância no exame de como, quando e por quem atividades com a escrita eram iniciadas e desenvolvidas na turma observada. A contraposição de diferentes formas de análise e de representação da interação entre participantes em eventos de letramento evidenciou que ora a professora, ora os alunos tornavam a escrita integrante das interações estabelecidas entre eles. Além disso, foi possível reconhecer aspectos que contribuem para a ocorrência de situações de incompreensão entre os participantes do grupo. O engajamento das crianças nos eventos de letramento permite argumentar que há um esforço, individual e coletivo, das mesmas em se posicionarem como leitoras e escritoras no espaço da sala de aula.

    Full Text Available O objetivo deste experimento clínico foi determinar a freqüência dos exames considerados dispensáveis numa rotina pré-operatória de facectomias e avaliar os gastos com eles. Se o paciente foi sorteado para testes-seletivos, solicitou-se que nenhum teste fosse executado, a menos que o paciente apresentasse um novo problema médico, ou piora de uma doença preexistente, a qual requeresse os testes independentemente da realização da cirurgia. Para pacientes sorteados para testes-rotineiros, foram solicitados: eletrocardiograma, dosagem de hemoglobina e glicemia de jejum. Foram calculados os gastos com exames considerados desnecessários. A amostra de 1.025 pacientes incluiu 513 sorteados para testes seletivos e 512 para testes rotineiros. A freqüência de eventos adversos intra-operatórios foi semelhante nos dois grupos (p = 0,923. O grupo de testes seletivos realizou de 60,7% menos exames que o de testes rotineiros. Os resultados sugerem que a requisição seletiva de exames pré-operatórios em facectomias, além de não prejudicar o paciente do ponto de vista de complicações clínicas intra-operatórias, possibilita expressiva economia de recursos quando comparada à atual rotina.The objective of this clinical trial was to determine the frequency of medical tests considered unnecessary in routine preoperative evaluation for cataract surgery. Unnecessary costs with these tests were also evaluated. For patients assigned to the selective testing group, it was requested that no preoperative testing be performed unless the patient presented a new or worsening medical problem warranting medical evaluation with testing. For patients assigned to the routine testing group, three tests were requested: a 12-lead electrocardiogram, complete blood count, and serum glucose level. The costs of tests considered unnecessary were calculated. The sample of 1,025 patients consisted of 512 assigned to the routine testing group and 513 to the selective

    Full Text Available Embora SAOS seja uma patologia comum, é frequentemente subdiagnosticada. Seus sinais e sintomas são, na sua maioria, subjetivos e, portanto, deve haver suspeição diagnóstica quando existir roncos, sonolência diurna, cansaço, desânimo e alteração de humor. Escalas e tabelas com boa sensibilidade, que incluem os sintomas clínicos mais relevantes e dados do exame físico, podem indicar o diagnóstico de SAOS. A confirmação diagnóstica é realizada através de polissonografia, considerada o método padrão ouro.Although obstructive sleep apnea syndrome is a common disease, it often goes undiagnosed. The signs and symptoms of the syndrome are mostly subjective. Therefore, snoring, daytime sleepiness, fatigue, dejection and mood changes should raise the suspicion of obstructive sleep apnea syndrome. Scales and tables that have good sensitivity and include the most relevant clinical symptoms and physical examination results can suggest a diagnosis of obstructive sleep apnea syndrome. The diagnosis is confirmed by polysomnography, which is considered the gold standard method.

  13. The Latin Matura exam

    Full Text Available In students' opinion the tasks of this year's Pre-Matura exam are neither too easy nor too difficult. 51 % of  the students claim that the translation from Slovene to Latin is the most difficult task, which is not surprising. The students have to recognise the appropriate grammatical constructions without the help of any comments. In this way they can show their autonomy in the use of  the language. Very high quality of the Latin Matura exam tasks can be clearly seen from graph 3. Namely, the students have quite different opinions on which task is the most difficult and which one the easiest. This means that each student can find the type of a task that suits them most and so they can excel in that particular area. At the oral part of the exam 46 % of the students would like to eliminate the grammar question, as they find it difficult to define grammar rules precisely, while they do not have any problems using them in a sentence. Quite surprisingly there are 20 % who dislike the question from culture and civilisation. Their main argument is that in this way they would be able to save a lot of time and so concentrate on other areas. According to the students, the good points of the Latin Matura exam are: a better insight into Latin language and Roman culture, and a good foundation for further study at the university. As far as the bad points of the exam are concerned, they mostly complain about the translation from Latin to Slovene, as they believe they do not have a lot of freedom in translating. They also wish there were more books with different types of  Matura exercises. Teachers mainly agree with their students, but they also pointed out a certain problem: it can be quite tempting to deal only with the topics appearing at the Latin Matura exam and eliminate all others. Namely, every teacher wants to prepare their students for the exam in the best possible way, as they feel their pedagogical and  professional skills are tested too.

    This work consisted in the evaluation of the entrance skin air kerma (ESAK) in pediatric chest x-ray examinations. A study of 186 exams in anterior-posterior, posterior-anterior and lateral projections was carried out for patients with ages ranging from 0 to 15 years. The ESAK was measured with the DoseCal software and Li-Fl thermoluminescent dosimeters. The results were compared with measurements done recently at the same place and with the reference dose values established by the European Community. It was observed that the optimization of the technique and the routine changes suggested in the previous study were not maintained. The charge (mAs) and the ESAK values found in the present study were much higher than the previous one, and the voltage (kVp) values found was lower. The results suggest that the implementation of the Quality Assurance Program could adequate these parameters to the established levels and keep the pediatric examinations more uniform. (author)

    Full Text Available OBJETIVO: Estudar aspectos da epidemiologia da hepatite B em pessoas submetidas à coleta de sangue em unidades de saúde. MÉTODOS: Indivíduos dos quais se coletou sangue em unidades de saúde de Ribeirão Preto, independentemente do motivo, foram solicitados a fornecer uma quantidade adicional de material, obtida no momento da coleta e submetida à detecção de marcadores de hepatite B. Simultaneamente, por meio de questionário padronizado, foram obtidas informações de possíveis fatores de risco para a doença. Os dados foram analisados por meio de um modelo de regressão logística. RESULTADOS: As prevalências de HBsAg e de anti-HBcAg foram de 0,3% e 13,9%, respectivamente. Os fatores de risco associados à infecção foram: idade, residência na cidade há menos de um ano, antecedente de hepatite, exposição prévia a casas de correção e homo/bissexualismo masculino. CONCLUSÕES: Devido a dificuldades crescentes de obtenção de sangue de indivíduos sadios, essa pode ser uma alternativa para estudos que objetivem fornecer informações sobre a circulação de agentes infecciosos na população. Embora não se possa generalizar os dados obtidos pela metodologia usada, ela traz conhecimento referente à circulação do vírus de hepatite B.OBJECTIVE: To study some of the epidemiological aspects of hepatitis B in a non-representative sample of patients seen in health care clinics. METHODS: The study population comprised 632 patients who were seen at health care clinics in the city of Ribeirão Preto, Brazil, for the purpose of blood testing, regardless the reason. After signing a written consent, an additional amount of blood was drawn from the same venous puncture site used to collect the original sample for the testing assigned to the patient at the health care clinic. A questionnaire was applied to each participant, looking for the presence of risk factors for hepatitis B. The blood samples were tested for HBV markers, using

    Objective: the present study is aimed at showing the different characteristics of pharyngoceles in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) and its correlation with clinical presentation. Material and method: pharyngocele cases were selected in imaging exams (video fluoroscopic swallowing exam [VFSE] and computed tomography) realized in our service, realizing clinical presentation correlation. Results: pharyngocele presents frequently with small dimensions and narrow orifice. When the size enlarges, clinical presentation is more evident and diverse, which can confuse with other cervical lesions that enlarge with Valsalva maneuver. Differential diagnosis can be done by imaging evaluation. Conclusion: we intended to demonstrate that many times pharyngocele can be presented with different aspects, not always being easy to recognize by clinics or imaging exams, but its diagnosis must be always remembered in our daily practice.

    Full Text Available RESUMO: Este estudo teve como objetivo apresentar de forma detalhada dados morfológicos e morfométricos da articulação umerorradioulnar de cães de raça definida avaliados por meio de exames físicos, radiográficos e tomográficos. A amostra dessa pesquisa constituiu-se de 44 cotovelos de cães com idades variadas. Para análise de informações obtidas, o coeficiente kappa e de correlação interclasse e associação foram realizados. Constatou-se que o desempenho individual de cada projeção radiográfica teve pobre concordância com o exame tomográfico; não houve concordância entre os observadores para as mensurações do ângulo da incisura ulnar ao exame radiográfico e tomográfico. Porém houve boa/moderada concordância para mensuração da incongruência radioulnar no plano sagital entre os observadores. Concluiu-se que nenhuma das cinco incidências radiográficas foi superior para análise radiográfica, uma vez que cada projeção apresentou melhor identificação de um compartimento do cotovelo. Medidas ao exame tomográfico para incongruência radioulnar não apresentaram reprodutibilidade no plano de reconstrução frontal, entretanto no corte sagital apresentaram boa e moderada concordância entre os observadores e que a mensuração do ângulo da incisura ulnar não apresentou repetibilidade ao exame radiográfico e nem reprodutibilidade ao exame tomográfico. Esses resultados contribuem para melhor utilização de cada exame de acordo com a região a ser avaliada bem como ressaltam a necessidade da somatória de múltiplos exames de imagem para a correta avaliação desta afecção.

    Full Text Available A problem faced by many instructors is that of designing exams that accurately assess the abilities of the students. Typically, these exams are prepared several days in advance, and generic question scores are used based on rough approximation of the question difficulty and length. For example, for a recent class taught by the author, there were 30 multiple choice questions worth 3 points, 15 true/false with explanation questions worth 4 points, and 5 analytical exercises worth 10 points. We describe a novel framework where algorithms from machine learning are used to modify the exam question weights in order to optimize the exam scores, using the overall final score as a proxy for a student’s true ability. We show that significant error reduction can be obtained by our approach over standard weighting schemes, i.e., for the final and midterm exam, the mean absolute error for prediction decreases by 90.58% and 97.70% for linear regression approach respectively resulting in better estimation. We make several new observations regarding the properties of the “good” and “bad” exam questions that can have impact on the design of improved future evaluation methods.

    In this work the radiological protection conditions and dose at the entrance of pediatric patients undergoing dental intraoral radiographs were evaluated. The study was conducted in two clinics of the dentistry course at the Federal University of Pernambuco, Recife, PB, Brazil, equipped with conventional X-ray apparatus, with 60 and 70 kV. 254 exams of 113 patients between the ages of 3 to 12 years were evaluated. The skin entrance dose was estimated using TLD-100 thermoluminescent dosemeters. During the examination were also recorded information regarding the time of exposure, radiographic technique used, use of thyroid protectors and lead apron, angle and distance of the cone Locator to the patient's skin. The results showed that the input skin doses ranged from 0.3 mGy to 10mGy. The lead apron was used in 71% of exams while the thyroid shield was only used in 58% of the exams. The exposure times ranged from 0,5s to 1,5s. From the results it can be concluded that the radiological procedures are not optimized and that in some cases the patient dose is high.

    Full Text Available Introduction: The Ultrasound Screening Exam for Underlying Lesions (USEFUL was developed in an attempt to establish a role for bedside ultrasound in the primary and preventive care setting. It is the purpose of our pilot study to determine if students were first capable of performing all of the various scans required of our USEFUL while defining such an ultrasound-assisted physical exam that would supplement the standard hands-on physical exam in the same head-to-toe structure. We also aimed to assess the time needed for an adequate exam and analyze if times improved with repetition and previous ultrasound training. Methods: Medical students with ranging levels of ultrasound training received a 25-minute presentation on our USEFUL followed by a 30-minute hands-on session. Following the hands-on session, the students were asked to perform a timed USEFUL on 2-3 standardized subjects. All images were documented as normal or abnormal with the understanding that an official detailed exam would be performed if an abnormality were to be found. All images were read and deemed adequate by board eligible emergency medicine ultrasound fellows. Results: Twenty-six exams were performed by 9 students. The average time spent by all students per USEFUL was 11 minutes and 19 seconds. Students who had received the University of California, Irvine School of Medicine’s integrated ultrasound curriculum performed the USEFUL significantly faster (p< 0.0025. The time it took to complete the USEFUL ranged from 6 minutes and 32 seconds to 17 minutes, and improvement was seen with each USEFUL performed. The average time to complete the USEFUL on the first standardized patient was 13 minutes and 20 seconds, while 11 minutes and 2 seconds, and 9 minutes and 20 seconds were spent performing the exam on the second and third patient, respectively. Conclusion: Students were able to effectively complete all scans required by the USEFUL in a timely manner. Students who have

  6. Do Collaborative Exams Really Promote Learning?

    Science.gov (United States)

    Miller, Scott; James, C. Renee

    2018-01-01

    Collaborative, two-stage exams are becoming more popular in physics and astronomy courses, and their supposed benefits in terms of collaborative learning have been reported in the field of physics. In a collaborative, two-stage exam, students first complete an exam individually. Once that portion of the exam is over, students then retake all or part of the exam within a group, where they are able to discuss the questions with their peers and arrive at a common answer. While there are a number of papers that discuss the purported benefits of this method from a collaborative point of view, few, if any discuss the actual benefits in terms of student learning. One paper found that when students were presented with previous exam questions a few weeks later, they performed better on questions covered previously in the group portion of the exam compared to similar questions which were tested but not part of the group portion. But, when students were retested on exam questions which were administered earlier, roughly six to seven weeks beforehand, no difference was found in their performance on the two sets of questions.We present preliminary findings comparing student performance levels on multiple sets of exam questions administered to students in an introductory astronomy course where two-stage exams are administered. Questions were administered first in an exam during the course of the semester, then again during a final exam. During the semester exams, one set of questions was also contained within the group portion of the exam, while questions similar in concept and difficulty were not. A comparison of student performance on these two sets of questions are compared to evaluate the usefulness of collaborative exams to promote learning.

O intervalo entre a realização dos exames foi curto, pois 65,8% das mulheres repetiram o exame com até um ano. Após o ajuste para fatores de confundimento foram associados à não realização do Papanicolaou: não ter companheiro, ter cinco a oito anos de escolaridade, não ter realizado consulta médica nos três últimos meses e morar em domicílio cujo chefe de família tem ocupação manual não especializada. Ter tido de dois a quatro parceiros sexuais nos três últimos meses foi associado a menor risco de não realização do preventivo. Em capital do Nordeste, a cobertura do exame preventivo de Papanicolaou foi semelhante à relatada em outros estudos nacionais. Entretanto, algumas mulheres realizaram citologias desnecessárias a intervalos curtos, implicando em desperdício de recursos e dificultando o acesso aos grupos mais vulneráveis que apresentaram maiores riscos de não testagem.In 1998, 465 women from 25 to 49 years of age, inhabitants of the municipality of São Luís, Maranhão, Brazil were interviewed to estimate Pap smear coverage, interval between tests and to identify factors associated with not performing Pap smears.

    This article aims to deconstruct various design qualities and strategies of clinic exam rooms, and discuss how they influence users' interaction and behavior in the space. Relevant literature supports the advantages and disadvantages of different design strategies. Annotated exam room prototypes illustrate the design qualities and strategies discussed. Advancements in technology and medicine, along with new legislative policies, are influencing the way care providers deliver care and ultimately clinic exam room designs. The patient-centered medical home model has encouraged primary care providers to make patients more active leaders of their health plan which will influence the overall functionality and configuration of clinic exam rooms. Specific design qualities discussed include overall size, location of doors and privacy curtains, positioning of exam tables, influence of technology in the consultation area, types of seating, and placement of sink and hand sanitizing dispensers. In addition, future trends of exam room prototypes are presented. There is a general lack of published evidence to support design professionals' design solutions for outpatient exam rooms. Future research should investigate such topics as the location of exam tables and privacy curtains as they relate to patient privacy; typical size and location of consultation table as it relates to patient connection and communication; and placement of sinks and sanitization dispensers as they relate to frequency and patterns of usage.

  1. Radiation exams in occupational medical evaluations

    International Nuclear Information System (INIS)

    Gelsleichter, A.M.; Hunh, A.; Nandi, D.M.

    2017-01-01

    Introduction: In occupational medicine, medical care must be geared toward the prevention of worker health. However, occupational medical exams often seek only through rigorous screening, reduce absenteeism, and thus increase productivity. To meet this goal, many institutions include radiological examinations indiscriminately in their medical and expert evaluations, contrary to the principle of justification. Objective: To provide a reflection about the presence of radiological exams in occupational medical evaluations. Methodology: Literary review including legislation related to the research topic. Results: Portaria 453/98 ANVISA prohibits the performance of radiological examinations for employment or expert purposes, except in cases where the exam may bring a benefit to the health of the individual examined or to society. However, in some situations the Norma Regulamentadora number 7 of the Ministry of Labor and Employment provides for radiological exams as a parameter for monitoring occupational exposure. Article 168 of the Consolidation of Labor Laws also prescribes that additional examinations may be required, at the medical discretion, to determine the physical and mental fitness of the employee for the job. Conclusion: Although there are legal provisions that prohibit and others that allow radiological exams in medical occupational evaluations, companies and institutions should take into account that any radiological exam has a risk involved and should not request them in a compulsory and indiscriminate manner. Radiological exams are only permissible to elucidate the diagnostic hypothesis produced by clinical evaluation, in order to provide a real benefit for the individual

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A avaliação pré-operatória tem como objetivos diminuir a morbimortalidade do paciente cirúrgico, o custo do atendimento perioperatório e a ansiedade pré-operatória. A partir da avaliação clínica deve-se definir a necessidade de exames complementares e estratégias para reduzir o risco anestésico-cirúrgico. O objetivo deste trabalho foi avaliar o benefício de exames de rotina pré-operatório de pacientes de baixo risco em cirurgias de pequeno e médio porte. MÉTODOS: Trata-se de um estudo descritivo, transversal, com 800 pacientes atendidos no consultório de avaliação pré-anestésica do Hospital Santo Antonio, Salvador, BA. Foram incluídos pacientes de 1 a 45 anos, estado físico ASA I, que seriam submetidos a cirurgias eletivas de pequeno e médio porte. Avaliaram-se alterações no hemograma, coagulograma, eletrocardiograma, RX de tórax, glicemia, função renal e dosagem de sódio e potássio e as eventuais mudanças de conduta que ocorreram decorrentes dessas alterações. RESULTADOS: Dos 800 pacientes avaliados, 97,5% fizeram hemograma, 89% coagulograma, 74,1% eletrocardiograma, 62% RX de tórax, 68% glicemia de jejum, 55,7% dosagens séricas de ureia e creatinina e 10,1% dosagens de sódio e potássio séricos. Desses 700 pacientes, 68 (9,71% apresentaram alteração nos exames pré-operatórios de rotina e apenas 10 (14,7% dos considerados alterados tiveram conduta pré-operatória modificada, ou seja, solicitação de novos exames, interconsulta ou adiamento do procedimento. Nenhuma das cirurgias foi suspensa. CONCLUSÃO: Observou-se que excessivos exames complementares são solicitados no pré-operatório, mesmo em pacientes jovens, de baixo risco cirúrgico, com pouca ou nenhuma interferência na conduta perioperatória. Exames aboratoriais padronizados não são bons instrumentos de screening de doenças, além de gerar gastos elevados e desnecessários.OBJETIVOS Y JUSTIFICATIVA: La

    The authors of this commentary discuss the recently completed review of the current Medical College Admission Test (MCAT), which has been used since 1991, and describe the blueprint for the new test that will be introduced in 2015. The design of the MCAT exam reflects changes in medical education, medical science, health care delivery, and the needs of the populations served by graduates of U.S. and Canadian medical schools. The authors describe how balancing the ambitious goals for the new exam and the varying priorities of the testing program's many stakeholders made blueprint design complex. They discuss the tensions and trade-offs that characterized the design process as well as the deliberations and data that shaped the blueprint.The blueprint for the MCAT exam balances the assessment of a broad range of competencies in the natural, social, and behavioral sciences and critical analysis and reasoning skills that are essential to entering students' success in medical school. The exam will include four sections: Biological and Biochemical Foundations of Living Systems; Chemical and Physical Foundations of Biological Systems; Psychological, Social, and Biological Foundations of Behavior; and Critical Analysis and Reasoning Skills.The authors also offer recommendations for admission committees, advising them to review applicants' test scores, course work, and other academic, personal, and experiential credentials as part of a holistic admission process and in relation to their institutions' educational, scientific, clinical, and service-oriented goals.

    2009-04-01

    This study examined why some high achievers on the course final exam were unsuccessful on the proficiency exam in English. We hypothesized that the learning motives and learning behaviors (learning strategy, learning time) had different effects on the outcomes of the exams. First, the relation between the variables was investigated using structural equation modeling. Second, the learning behaviors of students who got good marks on both exams were compared with students who did well only on the course final exam. The results were as follows. (a) Learning motives influenced test performance via learning behaviors. (b) Content-attached motives influenced all variables concerning learning behaviors. (c) Content-detached motives influenced all variables concerning learning behaviors that were related only to the course final exam. (d) The students who got good marks on both exams performed the learning behaviors that were useful on the proficiency exam more frequently than the students who did well only on the course final exam.

Os objetivos desta pesquisa foram analisar se os exames pré-operatórios em cirurgias eletivas são solicitados segundo critério clínico e avaliar os custos desnecessários para a instituição. Métodos: foram avaliadas as solicitações de exames pré-operatórios em pacientes adultos submetidos a cirurgias eletivas não cardíacas. Os exames foram solicitados pelos cirurgiões, conforme protocolo do Serviço de Anestesia. Foram avaliados dados demográficos, estado físico, comorbidades e tipo de exame complementar solicitado. Os exames feitos foram comparados com os exames indicados. O custo dos exames foi baseado na tabela Datasus. Resultados: foram avaliados 1.063 pacientes. Verificou-se que 41,9% dos exames feitos nos pacientes classificados como ASA I não estavam indicados. No grupo de risco ASA II foram feitos 442 exames (17,72% sem necessidade. Perceberam-se elevadas porcentagens na solicitação de hemograma, creatinina, coagulograma, raios X de tórax e ECG nos grupos ASA I-II. Apenas 40 (5,25% dos exames feitos no grupo ASA III não estavam indicados. Nos pacientes do grupo ASA IV, 22,5% dos exames necessários não foram feitos.

    2018-07-01

    Diabetic retinopathy is a common microvascular complication of diabetes mellitus and is the leading cause of new blindness among working-age adults in the United States. Timely intervention to prevent vision loss is possible with early detection by regular eye examinations. Unfortunately, adherence to recommended annual diabetic eye exams is poor. Public health interventions have targeted traditional barriers to care, such as cost and transportation, with limited success. Behavioral economics provides an additional framework of concepts and tools to understand low screening rates and to promote regular diabetic eye exams for populations at risk. In particular, behavioral economics outlines biases and heuristics that affect decision-making and underlie pervasive barriers to care, such as not viewing diabetic eye exams as a priority or perceiving oneself as too healthy to need an examination. In this review, we examine the literature on the use of behavioral economics interventions to promote regular diabetic eye exams. From the results of the included studies, we outline how concepts from behavioral economics can improve eye examination rates. In particular, the default bias, present bias, and self-serving bias play a significant role in precluding regular diabetic eye examinations. Potential tools to mitigate these biases include leveraging default options, using reminder messages, providing behavioral coaching, applying commitment contracts, offering financial incentives, and personalizing health messages. When combined with traditional public health campaigns, insights from behavioral economics can improve understanding of pervasive barriers to care and offer additional strategies to promote regular preventive eye care for patients with diabetes.

    In stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. To determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (FAST) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. We performed a prospective observational study by performing primary and secondary ultrasound exams in blunt abdominal trauma patients. All ultrasound exams were performed by four radiology residents who had the experience of more than 400 FAST exams. Five routine intraperitoneal spaces as well as the interloop space were examined by ultrasound in order to find free fluid. All patients who expired or were transferred to the operating room before the second exam were excluded from the study. All positive ultrasound results were compared with intra-operative and computed tomography (CT) findings and/or the clinical status of the patients. Primary ultrasound was performed in 372 patients; 61 of them did not undergo secondary ultrasound exam; thus, were excluded from the study.Three hundred eleven patients underwent both primary and secondary ultrasound exams. One hundred and two of all patients were evaluated by contrast enhanced CT scan and 31 underwent laparotomy. The sensitivity of ultrasound exam in detecting intraperitoneal fluid significantly increased from 70.7% for the primary exam to 92.7% for the secondary exam. Examining the interloop space significantly improved the sensitivity of ultrasonography in both primary (from 36.6% to 70.7%) and secondary (from 65.9% to 92.7%) exams. Performing a secondary ultrasound exam in stable blunt abdominal trauma patients and adding interloop space scan to the routine FAST exam significantly increases the sensitivity of ultrasound in detecting intraperitoneal free fluid

    Coletta, Vincent; Wikholm, Colin; Pascoe, Daniel

    2018-03-01

    Most physics instructors believe that adequate sleep is important in order for students to perform well on problem solving, and many instructors advise students to get plenty of sleep the night before an exam. After years of giving such advice to students at Loyola Marymount University (LMU), one of us decided to find out how many hours students actually do sleep the night before an exam, and how that would relate to their performance. The effect of inadequate sleep on exam performance was explored in a second-semester introductory physics course. At the end of the final exam, students reported the number of hours they slept the night before. Sleep deprivation corresponded to lower final exam scores. The main purpose of this study is to provide evidence that instructors can provide to their students to convince them that their time is better spent sleeping rather than studying all night before an exam.

    2018-03-01

    Full Text Available The weighting of a final exam or a final assignment is an essential part of course design that is rarely discussed in pedagogical literature. Depending on the weighting, a final exam or assignment may provide unequal benefits to students depending on their prior performance in the class. Consequently, uncritical grade weighting can discount student learning, by ensuring that improved mastery of material at the semester’s end is not reflected in the course grade. Problems related to several common final exam weights are explored, as are potential solutions to unequal student outcomes made possible by uncritical grade weighting. Ultimately, this essay argues that choosing a weight for a final exam or a final assignment determines what types of student success ought to be possible in the class; therefore, instructors should assign exam weights intentionally, being fully aware of the potential benefits and problems of the weights that they choose.

    Recent reform efforts in undergraduate biology have recommended transforming course exams to test at more cognitively challenging levels, which may mean including more cognitively challenging and more constructed-response questions on assessments. However, changing the characteristics of exams could result in bias against historically underserved groups. In this study, we examined whether and to what extent the characteristics of instructor-generated tests impact the exam performance of male and female and middle/high- and low-socioeconomic status (SES) students enrolled in introductory biology courses. We collected exam scores for 4810 students from 87 unique exams taken across 3 yr of the introductory biology series at a large research university. We determined the median Bloom’s level and the percentage of constructed-response questions for each exam. Despite controlling for prior academic ability in our models, we found that males and middle/high-SES students were disproportionately favored as the Bloom’s level of exams increased. Additionally, middle/high-SES students were favored as the proportion of constructed-response questions on exams increased. Given that we controlled for prior academic ability, our findings do not likely reflect differences in academic ability level. We discuss possible explanations for our findings and how they might impact how we assess our students. PMID:27252299

    Fractures and dislocations of the hand are some of the most frequently encountered injuries of the musculoskeletal system traumas. To evaluate these lesions radiography is the investigation of choice, and is rarely needed the help of other images to establish the diagnosis and treatment. The image quality of the X-ray examination is therefore essential. In this study a homogeneous phantom hand was developed for use in the hand image optimization process. In this procedure were quantified for different tissue thicknesses which are an anthropomorphic hand phantom. To perform the classification and quantification of tissue was applied membership functions in histograms of CT scans. The same procedure was adopted for 30 retrospective examinations of patients in the Hospital of the Faculty of Medicine of Botucatu UNESP (HCFMB-UNESP). The homogeneous phantom built was used to calibrate the techniques used in clinical routine (RC). Such calibrated techniques were used to acquire images of anthropomorphic phantom. These images were analyzed by Visual Grading Method (VFA) by experienced radiologists in the area. The image with better grade in AGV and lower dose was chosen as the Gold Standard. The results showed concordance between the tissue thicknesses which constitute the anthropomorphic phantom and the sample evaluated patients, with variations between 12.63% and 6.48% for soft tissue and bone, respectively. The Gold Technical Standard compared with the technique normally used in the CR reduces dose charge 41.28% and 33.18% in the tube.

    Aseptic technique includes the use of sterile surgical gloves for survival surgeries in rodents to minimize the incidence of infections. Exam gloves are much less expensive than are surgical gloves and may represent a cost-effective, readily available option for use in rodent surgery. This study examined the effectiveness of surface disinfection of exam gloves with 70% isopropyl alcohol or a solution of hydrogen peroxide and peracetic acid (HP–PA) in reducing bacterial contamination. Performance levels for asepsis were met when gloves were negative for bacterial contamination after surface disinfection and sham ‘exertion’ activity. According to these criteria, 94% of HP–PA-disinfected gloves passed, compared with 47% of alcohol-disinfected gloves. In addition, the effect of autoclaving on the integrity of exam gloves was examined, given that autoclaving is another readily available option for aseptic preparation. Performance criteria for glove integrity after autoclaving consisted of: the ability to don the gloves followed by successful simulation of wound closure and completion of stretch tests without tearing or observable defects. Using this criteria, 98% of autoclaved nitrile exam gloves and 76% of autoclaved latex exam gloves met performance expectations compared with the performance of standard surgical gloves (88% nitrile, 100% latex). The results of this study support the use of HP–PA-disinfected latex and nitrile exam gloves or autoclaved nitrile exam gloves as viable cost-effective alternatives to sterile surgical gloves for rodent surgeries.

    2006-07-01

    Full Text Available The reliability and validity of professionally written multiple-choice exams have been extensively studied for exams such as the SAT, graduate record examination, and the force concept inventory. Much of the success of these multiple-choice exams is attributed to the careful construction of each question, as well as each response. In this study, the reliability and validity of scores from multiple-choice exams written for and administered in the large introductory physics courses at the University of Illinois, Urbana-Champaign were investigated. The reliability of exam scores over the course of a semester results in approximately a 3% uncertainty in students’ total semester exam score. This semester test score uncertainty yields an uncertainty in the students’ assigned letter grade that is less than 1 / 3 of a letter grade. To study the validity of exam scores, a subset of students were ranked independently based on their multiple-choice score, graded explanations, and student interviews. The ranking of these students based on their multiple-choice score was found to be consistent with the ranking assigned by physics instructors based on the students’ written explanations ( r>0.94 at the 95% confidence level and oral interviews (r=0.94−0.09+0.06 .

    This paper is about the design and implementation of an examination system based on World Wide Web. It is called FLEX-Flight License Exam Software. We designed and implemented flexible and modular software architecture. The implemented system has basic specifications such as appending questions in system, building exams with these appended questions and making students to take these exams. There are three different types of users with different authorizations. These are system administrator, operators and students. System administrator operates and maintains the system, and also audits the system integrity. The system administrator can not be able to change the result of exams and can not take an exam. Operator module includes instructors. Operators have some privileges such as preparing exams, entering questions, changing the existing questions and etc. Students can log on the system and can be accessed to exams by a certain URL. The other characteristic of our system is that operators and system administrator are not able to delete questions due to the security problems. Exam questions can be inserted on their topics and lectures in the database. Thus; operators and system administrator can easily choose questions. When all these are taken into consideration, FLEX software provides opportunities to many students to take exams at the same time in safe, reliable and user friendly conditions. It is also reliable examination system for the authorized aviation administration companies. Web development platform - LAMP; Linux, Apache web server, MySQL, Object-oriented scripting Language - PHP are used for developing the system and page structures are developed by Content Management System - CMS.

    Background: Prone imaging has been demonstrated to minimize diaphragmatic and breast tissue attenuation. Objectives: To determine the role of prone imaging on the reduction of unnecessary rest perfusion studies and coronary angiographies performed, thus decreasing investigation time and radiation exposure. Methods: We examined 139 patients, 120 with an inferior wall and 19 with an anterior wall perfusion defect that might represented attenuation artifact. Post-stress images were acquired in both the supine and prone position. Coronary angiography was used as the 'gold standard' for evaluating coronary artery patency. The study was terminated and rest imaging was obviated in the presence of complete improvement of the defect in the prone position. Quantitative interpretation was performed. Results were compared with clinical data and coronary angiographic findings. Results: Prone acquisition correctly revealed defect improvement in 89 patients (89/120) with inferior wall and 12 patients (12/19) with anterior wall attenuation artifact. Quantitative analysis demonstrated statistically significant difference in the mean summed stress scores (SSS) of supine and mean SSS of prone studies in patients with disappearing inferior wall defect in the prone position and patent right coronary artery (true negative results). The mean difference between SSS in supine and in prone position was higher with disappearing than with remaining defects. Conclusion: Technetium-99m (Tc-99m) tetrofosmin myocardial perfusion imaging with the patient in the prone position overcomes soft tissue attenuation; moreover it provides an inexpensive, accurate approach to limit the number of unnecessary rest perfusion studies and coronary angiographies performed.

RESULTADOS: Foram avaliadas 16 crianças, sendo a indicação mais comum do exame avaliação de traqueotomia prolongada em 10 pacientes (62%, seguida de avaliação de estenose subglótica em três casos (31,3%. Em 44% dos exames houve falha da NL em mostrar lesões em subglote. CONCLUSÃO: A avaliação endoscópica da via aérea infantil em crianças com dificuldade respiratória é essencial para o diagnóstico. Concluímos que todas as crianças com patologia de via aérea superior devem ser submetidas à nasolaringoscopia inicialmente, a qual é um exame barato, de fácil execução e que fornece dados importantes inclusive a respeito da funcionalidade da laringe. No entanto, se houver suspeita de patologia subglótica ou traqueal, ou ainda quando os dados nasolaringoscopia não são condizentes com exame físico, é essencial a realização da laringotraqueoscopia.It is not uncommon to find children with respiratory distress.

    To evaluate predictive validity of cognitive dysfunction of the Saint Louis University mental status (SLUMS) exam or mini-mental state exam (MMSE) for institutionalization and mortality after 7.5-years. Longitudinal study. Geriatric Research, Education and Clinical Center Veterans Affairs Hospital St. Louis, MO. Patients (N=705) were screened for cognitive dysfunction in 2003 using the SLUMS exam and MMSE, and mortality and institutionalization up to 7.5-years later were evaluated as outcome measures. The associations between outcome measures and MMSE and SLUMS exam total scores, and cognitive status were examined using Kaplan-Meier curves and Cox proportional-hazards regression. Five hundred thirty-three charts were reviewed, 176/533(33%) patients had died and 31/526 (6%) were institutionalized during 7.5-year follow-up period. All subjects were male with a mean age of 75 years and most had high school education or greater (71%). MMSE dementia, SLUMS dementia (ps<.001) and MCI (p<.05) groups had significantly lower survival rates than normal cognition group in the Kaplan-Meier curves. Scores classified as dementia on SLUMS (HR=2.4, 95% CI 1.6-3.7; p <.001) or MMSE (HR=2.3, 95% CI 1.5-3.6; p <.001) both predicted mortality and, also, institutionalization (SLUMS: HR=3.5, 95% CI 1.3-9.1; p <.01; MMSE: HR=3.8, 95% CI 1.6-9.0; p <.001) after adjustment for covariates. Unadjusted SLUMS exam MCI predicted morality (HR=1.5, 95% CI 1.1-2.2; p <.019) but not institutionalization. The SLUMS exam and MMSE both predict mortality and institutionalization for male patients screened as positive for dementia.

    Full Text Available As dificuldades para estabelecer diagnóstico precoce e de certeza da leptospirose levaram-nos a analisar as alterações histopatológicas do músculo gastrocnêmio e avaliar, originalmente, a utilidade de método imuno-histoquímico, da peroxidase-antiperoxidase, quando desejada a demonstração do espiroquetídeo e de seus produtos no referido tecido. O estudo histopatológico de biópsias da panturrilha configurou quadro de miosite, caracterizado pela correlação entre o infiltrado inflamatório intersticial e as anormalidades degenerativo-necróticas das fibras musculares. As lesões foram consideradas mínimas em 69,45% dos pacientes, moderadas em 19,45% e intensas em 5,55%, estando ausentes nos demais. Por seu turno, o método imuno-histoquímico enzimático identificou antígeno leptospirótico em 94,45%, configurando resultado muito expressivo.Establishing an early and certain diagnosis of leptospirosis has been a difficult task. So, we analysed the histopathological alterations of the gastrocnemius muscle, and studied, for the first time, the usefulness of the immune histochemical method of peroxidase-antiperoxidase for the demonstration of the spirochete and of its products in this tissue. Histopathological observations have shown a picture of miositis, characterized by interstitial inflammatory infiltrate and necrotic-degenerative abnormalities of muscle fibers. The lesions were considered minimal in 69.45% of the patients, moderate in 19.45%, severe in 5.55% and absent in the remaining. On the other hand, the immune histochemical method identified the etiology in 94.45% what was considered very expressive.

    To examine the relationship between study strategies and performance on a high stakes medical licensing exam entitled the United States Medical Licensing Examination Step 1. The action research project included seventy nine student participants at the Texas A & M Health Science Center College of Medicine during their pre-clinical education. Data collection included pre-matriculation and matriculation academic performance data, standardized exam data, and the Learning and Study Strategies Instrument. Multiple regression analyses were conducted. For both models, the dependent variable was the Step 1 score, and the independent variables included Medical College Admission Test, Undergraduate Grade Point Average, Year 1 Average, Year 2 Average, Customized National Board of Medical Examiners Average, Comprehensive Basic Science Exam score, and Learning and Study Strategy Instrument sub-scores. Model 2 added Comprehensive Basic Science Self-Assessment average. Concentration (Model 1 - β = .264; Model 2 - β = .254) was the only study strategy correlated with Step 1 performance. The other statistically significant predictors were Customized National Board of Medical Examiners Average (β = .315) and Year 2 Average (β = .280) in Model 1 and Comprehensive Basic Science Self-Assessment Average (β = .338) in Model 2. There does appear to be a relationship between the study strategy concentration and Step 1 licensing exam performance. Teaching students to practice and utilize certain techniques to improve concentration skills when preparing for and taking exams may help improve licensing exam scores.

  6. Does Question Structure Affect Exam Performance in the Geosciences?

    The jump to university level exams can be challenging for some students, often resulting in poor marks, which may be detrimental to their confidence and ultimately affect their overall degree class. Previous studies have found that question structure can have a strong impact on the performance of students in college level exams (see Gibson et al., 2015, for a discussion of its impact on physics undergraduates). Here, we investigate the effect of question structure on the exam results of geology and geophysics undergraduate students. Specifically, we analyse the performance of students in questions that have a 'scaffolded' framework and compare them to their performance in open-ended questions and coursework. We also investigate if observed differences in exam performance are correlated with the educational background and gender of students, amongst other factors. It is important for all students to be able to access their degree courses, no matter what their backgrounds may be. Broadening participation in the geosciences relies on removing systematic barriers to achievement. Therefore we recommend that exams are either structured with scaffolding in questions at lower levels, or students are explicitly prepared for this transition. We also recommend that longitudinal studies of exam performance are conducted within individual departments, and this work outlines one approach to analysing performance data.

    Recent reform efforts in undergraduate biology have recommended transforming course exams to test at more cognitively challenging levels, which may mean including more cognitively challenging and more constructed-response questions on assessments. However, changing the characteristics of exams could result in bias against historically underserved groups. In this study, we examined whether and to what extent the characteristics of instructor-generated tests impact the exam performance of male and female and middle/high- and low-socioeconomic status (SES) students enrolled in introductory biology courses. We collected exam scores for 4810 students from 87 unique exams taken across 3 yr of the introductory biology series at a large research university. We determined the median Bloom's level and the percentage of constructed-response questions for each exam. Despite controlling for prior academic ability in our models, we found that males and middle/high-SES students were disproportionately favored as the Bloom's level of exams increased. Additionally, middle/high-SES students were favored as the proportion of constructed-response questions on exams increased. Given that we controlled for prior academic ability, our findings do not likely reflect differences in academic ability level. We discuss possible explanations for our findings and how they might impact how we assess our students. © 2016 C. D. Wright, S. L. Eddy, et al.

On the basis of a research with a Brazilian men's magazine, VIP Exame, which involved the analysis of issues of the magazine as well as an observation of the working process of the reporters and journalists, I focus my comments on the way the masculine body is treated by the magazine and how a discourse emerges on masculinity where attention to "good looks" becomes an important feature of a successful masculinity. On the basis of these observations I go on to discuss feminist and other theories of the subject, in order to understand how the reflexive monitoring of the body is increasingly important in the constitution of gender identities.

    Full Text Available Abstract This article presents a review of the recommendations on supplementary exams employed for the clinical diagnosis of Alzheimer's disease (AD in Brazil published in 2005. A systematic assessment of the consensus reached in other countries, and of articles on AD diagnosis in Brazil available on the PUBMED and LILACS medical databases, was carried out. Recommended laboratory exams included complete blood count, serum creatinine, thyroid stimulating hormone (TSH, albumin, hepatic enzymes, Vitamin B12, folic acid, calcium, serological reactions for syphilis and serology for HIV in patients aged younger than 60 years with atypical clinical signs or suggestive symptoms. Structural neuroimaging, computed tomography or - preferably - magnetic resonance exams, are indicated for diagnostic investigation of dementia syndrome to rule out secondary etiologies. Functional neuroimaging exams (SPECT and PET, when available, increase diagnostic reliability and assist in the differential diagnosis of other types of dementia. The cerebrospinal fluid exam is indicated in cases of pre-senile onset dementia with atypical clinical presentation or course, for communicant hydrocephaly, and suspected inflammatory, infectious or prion disease of the central nervous system. Routine electroencephalograms aid the differential diagnosis of dementia syndrome with other conditions which impair cognitive functioning. Genotyping of apolipoprotein E or other susceptibility polymorphisms is not recommended for diagnostic purposes or for assessing the risk of developing the disease. Biomarkers related to the molecular alterations in AD are largely limited to use exclusively in research protocols, but when available can contribute to improving the accuracy of diagnosis of the disease.

  14. Developing a prelicensure exam for Canada: an international collaboration.

    Nine previously conducted studies indicate that Elsevier's HESI Exit Exam (E(2)) is 96.36%-99.16% accurate in predicting success on the National Council Licensure Examination for Registered Nurses. No similar standardized exam is available in Canada to predict Canadian Registered Nurse Examination (CRNE) success. Like the E(2), such an exam could be used to evaluate Canadian nursing students' preparedness for the CRNE, and scores on the numerous subject matter categories could be used to guide students' remediation efforts so that, ultimately, they are successful on their first attempt at taking the CRNE. The international collaboration between a HESI test construction expert and a nursing faculty member from Canada, who served as the content expert, resulted in the development of a 180-item, multiple-choice/single-answer prelicensure exam (PLE) that was pilot tested with Canadian nursing students (N = 175). Item analysis data obtained from this pilot testing were used to develop a 160-item PLE, which includes an additional 20 pilot test items. The estimated reliability of this exam is 0.91, and it exhibits congruent validity with the CRNE because the PLE test blueprint mimics the CRNE test blueprint. Copyright © 2013 Elsevier Inc.

    Due to the use of radiopharmaceutical positron-emitting in PET exam and realization of tomography by x-ray transmission in CT examination, an increase of dose with hybrid PET/CT technology is expected. However, differences of doses have been reported in many countries for the same type of procedure. It is expected that the dose is an influent parameter to standardize the protocols of PET/CT. This study aimed to estimate the effective doses and absorbed in 65 patients submitted to oncological Protocol in a nuclear medicine clinic in Rio de Janeiro, considering the risk of induction of cancer from the scan. The CT exam-related doses were estimated with a simulator of PMMA and simulated on the lmPACT resistance, which for program effective dose, were considered the weight factors of the lCRP 103. The PET exam doses were estimated by multiplying the activity administered to the patient with the ICRP dose 80 factors. The radiological risk for cancer incidence were estimated according to the ICRP 103. The results showed that the effective dose from CT exam is responsible for 70% of the effective total in a PET/CT scan. values of effective dose for the PET/CT exam reached average values of up to 25 mSv leading to a risk of 2, 57 x 10 -4 . Considering that in staging of oncological diseases at least four tests are performed annually, the total risk comes to 1,03x 10 -3

    Dilated fundoscopic exam is considered the gold standard for detecting retinal hemorrhage, but expertise in obtaining this exam is not always immediately available. MRI can detect retinal hemorrhages, but correlation of the grade or severity of retinal hemorrhage on dilated fundoscopic exam with retinal hemorrhage visibility on MRI has not been described. To determine the value of standard brain protocol MRI in detecting retinal hemorrhage and to determine whether there is any correlation with MR detection of retinal hemorrhage and the dilated fundoscopic exam grade of hemorrhage. We conducted a retrospective chart review of 77 children <2 years old who were seen for head trauma from April 2007 to July 2013 and had both brain MRI and dilated fundoscopic exam or retinal camera images. A staff pediatric radiologist and radiology resident reviewed the MR images. Retinal hemorrhages were graded by a chief ophthalmology resident on a 12-point scale based on the retinal hemorrhage type, size, location and extent as seen on review of retinal camera images and detailed reports by ophthalmologists. Higher scores indicated increased severity of retinal hemorrhages. There was a statistically significant difference in the median grade of retinal hemorrhage examination between children who had retinal hemorrhage detected on MRI and children who did not have retinal hemorrhage detected on MRI (P = 0.02). When examination grade was categorized as low-grade (1-4), moderate-grade (5-8) or high-grade (>8) hemorrhage, there was a statistically significant association between exam grade and diagnosis based on MRI (P = 0.008). For example, only 14% of children with low-grade retinal hemorrhages were identified on MRI compared to 76% of children with high-grade hemorrhages. MR detection of retinal hemorrhage demonstrated a sensitivity of 61%, specificity of 100%, positive predictive value of 100% and negative predictive value of 63%. Retinal hemorrhage was best seen on the gradient

Using the PACS system, regions of interest were delineated, where the mean and standard deviation of CT numbers for each protocol were been calculated. The optimization took into account the maintenance of the CT number and noise from images acquired with clinical protocols. It was observed that the protocols used in the service, in general, exhibit a low dose, despite the great variability among the different professional shifts. In examinations of the chest, skull and abdomen, changes in the values of mAs and pitch were suggested, allowing dose reductions (60%, 17% and 19%, respectively), without compromising the image diagnostic quality.

    Jaun, Bernhard; Thilgen, Carlo

    2018-02-01

    e-Learning has become increasingly important in chemical education and online exams can be an attractive alternative to traditional exams written on paper, particularly in classes with a large number of students. Ten years ago, we began to set up an e-course complementing our lecture courses Organic Chemistry I and II within the open-source e-learning environment Moodle. In this article, we retrace a number of decisions we took over time, thereby illustrating the challenges one faces when creating online exercises and exams in (organic) chemistry. Special emphasis is put on the development of MOSFECCS (MOlecular Structural Formula Editor and Calculator of Canonical SMILES), our new editor for drawing structural formulae and converting them to alphanumeric SMILES codes that can be submitted as answers to e-problems. Convinced that the possibility for structure input is essential to set up sensible chemistry quizzes and exams, and realising that existing tools present major flaws in an educational context, we decided to embark on the implementation of MOSFECCS which takes into account a number of didactic aspects.

  1. The justification principle applied to Computed tomography exams

    International Nuclear Information System (INIS)

    Machado Tejeda, A.; Mora Machado, R. de la; Garcia Moreira, T.; Hing Perdomo, J.

    2008-01-01

    The increasing use of imaging technologies and the installation of more sophisticated equipment in radiology services, such as multi-slice CT scanners have consequently increased the number of treated patients, as well as the collective doses to population. Radiation doses received from CT exams are higher than those received in conventional radiology. The optimal use of CT equipment, considering optimized techniques, and the justification of examinations, are imperative in order to minimize the undesirable effects of radiation. In this paper we do set out to the assessment of justification criteria applied for CT exams in a Cuban Hospital. The justification of prescribed tests by physicians was analyzed, assessing its incidence depending on the kind of studies and percentage (%) of positive and negative cases. The study was carried out in a Clinical Surgical Hospital in Havana City. This hospital has installed a Shimadzu SCT-7800TC helical single-slice device. The sample is made up of 81 patients, between 24 and 80 years old, both men and women. For all of them the pathology that causes the order of the exam as well as the existence of other previous tests, were considered. As a result of the assessment, the 56.8% of all cases turned out to be positives; the 55.5% only confirmed the pathologies and the 1.23% produced new evidences. On the other hand, the remaining 43.2% were negatives noting that the 65.3% of the patients there were not previous imaging tests. Skull exam was the most incidences compiling the 67.7% of cases, and it was the headache the most frequent clinical problem to perform the 41.1%. In terms of justification, the evaluation of prescriptions evidenced that CT exams were not justified in 43.2% of cases. As part of this last group, it was also found that 46.9% of clinical studies were negative. (author)

  3. Investigating the effects of exam length on performance and cognitive fatigue.

    Directory of Open Access Journals (Sweden)

    Jamie L Jensen

    Full Text Available This study examined the effects of exam length on student performance and cognitive fatigue in an undergraduate biology classroom. Exams tested higher order thinking skills. To test our hypothesis, we administered standard- and extended-length high-level exams to two populations of non-majors biology students. We gathered exam performance data between conditions as well as performance on the first and second half of exams within conditions. We showed that lengthier exams led to better performance on assessment items shared between conditions, possibly lending support to the spreading activation theory. It also led to greater performance on the final exam, lending support to the testing effect in creative problem solving. Lengthier exams did not result in lower performance due to fatiguing conditions, although students perceived subjective fatigue. Implications of these findings are discussed with respect to assessment practices.

    Full Text Available We have examined whether cadaver dissection by first year medical students (MIs affected their performance in two test measures: the NBME Gross Anatomy and Embryology Subject Exam (dissection-relevant questions only, and practical exams given at the end of each major section within the course. The dissections for the entire course were divided into 18 regional dissection units and each student was assigned to dissect one third of the regional units; the other two-thirds of the material was learned from the partner-prosected cadavers. Performance for each student on the exams was then assessed as a function of the regions those students actually dissected. While the results indicated a small performance advantage for MIs answering questions on material they had dissected on the NBME Subject Exam questions relevant to dissection (78-88% of total exam, the results were not statistically significant. However, a similar, small performance advantage on the course practical exams was highly significant.

    Developmental hip disorder (DHD) is a disorder in development of the acetabulum which remains abrupt (dysplasia) and probably consequential cranialisation of the femur head (luxation). The aim of this paper is to establish the total number of DHD and its subtypes at the first clinical and ultrasound exam of newborns in a retrospective-prospective study made in the period from 1st Jan 2006 through to 31 Dec 2010 at the Clinic for orthopaedics and traumatology in Banja Luka. In total 6132 patients were examined and 99 cases diagnosed with DHD (dysplasia and luxation). Ultrasonic exam was done by means of electronic probe of 5-12 MHz according to standard method after Graph. Girls were significantly more present (96%). Positive family anamnesis on DHD was present with 7.8% examinee, mainly with primiparas, and/ or with 77.8% children with DHD. Dominant intrauterine risk factors for DHD were: mal position of foetus in uterus (78.6%), oligoamnion (17.9%), malformation of the spinal column of the pregnant woman (3.6%), whereas with 38.4% of children with a certain form of DHD the following were found: breech presentation, caesarean section or twin pregnancy. The clinical exam indicated DHD with 8.87% examinee, out of which hip looseness was found with 5% examinees. Ultrasonic finding was positive with 99 examinee, that is with 1.61% of them (deficient and badly formed acetabulum, sleeked protrusion; 8 luxations and 91 dysplasia). Prophylactic measures were requested by 58.6% children (abductive bending and exercises), whereas 41.4 % needed non-intervention therapeutic measures (traction, Pavlik's straps, Graph's knickers, plastering), after which there were no children needing surgical correction of DHD. These data indicate that clinical exam is unreliable for DHD diagnostics, and that Ultrasonic diagnostics and treatment of DHD should start as early as possible applying atraumatic helping devices and procedures in the period when all structures are elastic, flexible and

    Bastawrous, Sarah; Carney, Benjamin

    2017-06-01

    In the current digital and filmless age of radiology, rates of unread radiology exams remain low, however, may still exist in unique environments. Veterans Affairs (VA) health care systems may experience higher rates of unread exams due to coexistence of Veterans Health Information Systems and Technology Architecture (VistA) imaging and commercial picture archiving and communication systems (PACS). The purpose of this patient safety initiative was to identify any unread exams and causes leading to unread exams. Following approval by departmental quality assurance committee, a comprehensive review was performed of all radiology exams within VistA imaging from July 1, 2009 to June 30, 2014 to identify unread radiology exams. Over the 5-year period, the total unread exam rate was calculated to be 0.17%, with the highest yearly unread exam rate of 0.25%. The leading majority of unread exam type was plain radiographs. Analysis revealed unfinished dictations, unassociated accession numbers, technologist errors, and inefficient radiologist work lists as top contributors to unread exams. Once unread radiology exams were discovered and the causes identified, valuable process changes were implemented within our department to ensure simultaneous tracking of all unread exams in VistA imaging as well as the commercial PACS.

    Eduardo Toshiyuki Moro

    2014-04-01

    Background: preoperative exams aim to identify disorders that may compromise the patient´s perioperative care. However, unnecessary tests rarely change the outcome, and are expensive to institution. The aim of this study was to evaluate the preoperative tests ordered in Santa Lucinda hospital, Sorocaba - SP. Methods: after approval by the Ethics Committee of PUC-SP University, we assessed pre-anesthetic evaluation of patients undergoing elective surgery from march to August, 2011. We recorded: age, sex, ASA physical status, the presence of coexisting diseases, medication use, type of surgery and preoperative tests. They were classified as sufficient, sufficient with unnecessary tests, insufficient, or insufficient with unnecessary tests. Results: two hundred and nineteen records were evaluated, of which 52% were considered sufficient, but with unnecessary tests. For 24% of patients, the tests were insufficient, with some ordered unnecessarily. To 8% of patients, the tests were insufficient, and only 16% didn´t have insufficient and unnecessary tests. The most frequently ordered tests were hematocrit and hemoglobin. The exams most unnecessarily ordered were coagulation tests and dosage of serum urea. Among the necessary examinations, but unsolicited, there were ECG (27%, electrolytes (13% and creatinine (11%. Seventy-nine tests showed some kind of problem, but they didn´t change in behavior. Conclusions: preoperative tests unnecessarily ordered are frequent, which do not guarantee that some patients present to surgery without fundamental exams according to their risk group.

    2013-05-01

    In light of the structural and content changes to the Medical College Admission Test (MCAT) to be implemented in 2015 and the recent diversity- and social-accountability-based recommendations of the Future of Medical Education in Canada (FMEC) project, the authors review and reexamine the use of the MCAT exam in Canadian medical school admissions decisions.This Perspective article uses a point-counterpoint format to discuss three main advantages and disadvantages of using the MCAT exam in the medical school admissions process, from a Canadian perspective. The authors examine three questions regarding the FMEC recommendations and the revised MCAT exam: (1) Is the MCAT exam equal and useful in Canadian admissions? (2) Does the MCAT exam affect matriculant diversity? and (3) Is the MCAT exam a strong predictor of future performance? They present the most recent arguments and evidence for and against use of the MCAT exam, with the purpose of summarizing these different perspectives for readers.

Tais imagens trazem o discurso oficial de especialistas e constroem narrativas, entendidas como verdades, alicerçadas no conhecimento científico. Apoiamo-nos no referencial teórico dos estudos culturais, pois suas reflexões ajudam a compreender que as subjetividades são social e culturalmente construídas por vários discursos e artefatos. Não negamos o que está representado, mas estabelecemos diálogos com outras possibilidades de leituras que podem estar presentes nestes artefatos. Entendemos essas imagens como pedagogias culturais - que se comportam como textos a serem lidos, construindo representações, as quais podem ser assumidas como efeitos de verdade - e que atribuem ao sujeito a necessidade de controlar constantemente suas ações. Ao reforçar a biomedicina, as instituições de saúde reproduzem uma visão unidimensional e desconsideram a complexidade desse problema. Entendemos que as pedagogias culturais fazem parte de um território de lutas, onde sentidos e significados podem ser reelaborados, produzindo identidades híbridas, que constroem suas matrizes identitárias nesse emaranhado de relações de poder.This article analyzes the images publicized on cigarettes packs that are part of the strategies from the Ministry of Health to combat the tabagism and available from the Cancer National Institute.

    2017-05-01

    Awareness of imaging utilization increased after implementation of Radiology Order Entry with decision support systems (ROE-DS). Our hypothesis is few exams with low Clinical Appropriateness Score (CAS) on ROE-DS are performed. Clinical indications of exams with CAS less than 3 (9-point scale) were re-reviewed and reports analyzed. Structured Query Language-based query retrieved exams with CAS less than 3 in ROE-DS from January 2007 to December 2011. Reasons provided by physicians for ordering these exams and reports of exams performed were analyzed. For each indication, number of exams ordered and performed was calculated. Statistical significance was assessed using Student's t test and χ 2 analysis (P < .05). From 445,984 exams, 12,615 exams (2.8%) had CAS less than 3, and 7,956 exams (63%) were performed. Reasons for ordering of 12,615 low CAS exams were as follows: Requests by physician specialists without further explanation (4,516 = 35.8%), notation of special clinical circumstances (2,877 = 22.8%), requests by nonphysician staff without further explanation (1,383 = 10.9%), absence of suspected finding on previous modality (1,099 = 8.7%), patient preference (737 = 5.8%), and requests based on radiologists' recommendations (706 = 5.6%). Difference between male and female (male < female) preferences for low CAS exams was statistically significant (P < .01). Imaging outcome was highest for extremity MRI cases (66.7%; P < .01). Less than 3% of exams ordered had low CAS and about two-thirds of these were performed. Most common indication for ordering these exams was physician specialist request based on opinion of medical necessity without specification. Extremity MRI constituted the highest positive findings for low CAS exams performed. Published by Elsevier Inc.

    2015-12-01

    Blood pressure (BP) elevation in medical office settings in patients who are normotensive in nonmedical settings is an effect known as 'white coat hypertension'. This phenomenon is thought to be due to situational anxiety caused by the experience of visiting a doctor and the anxiety-inducing nature of the medical office. Our study was designed to determine if carefully selected photographic art could counter the anxiety that causes white coat hypertension and lead to lower BP recordings in some patients. 117 adults, non-pregnant patients from the Louisiana State University Health Sciences Center Family Medicine Resident Clinic participated in this study. After the triage nurse measured the BP, the patients were randomly placed in either an exam room with standard medical posters (control room) or in an exam room with photographic art (photo room). The BP was measured in the exam room. After the medical visit, the patients switched rooms and the BP was measured a third time. The patients were asked to fill out a questionnaire to identify room preference. On average, the BP obtained in the control rooms was higher than that obtained in the photo rooms. There was a statistically significant difference between the mean arterial pressure, systolic BP and diastolic BP between the control room and the photo room. Landscape photographic art may have the beneficial effect of reducing BP in medical office examination rooms. Published by the BMJ Publishing Group Limited.

    Full Text Available The present work discusses how aspects such as identity, culture and difference are important aspects in for language teaching and learning environments. Using Woodward's (2011 definition that identity is marked by difference, we considered these aspects in foreign language teaching and learning contexts when we learn the laguage of others. In addition, we present a proficiency exam called EPPLE, aimed at language teachers, and we suggest the implementation of a task that addresses cultural issues, because we need to prepare language teachers that search not only for their linguistic and pedagogical knowledge construction, but also for their understanding about culture, identity and difference.

MÉTODOS: Foram investigados, consecutivamente, 130 pacientes não selecionados, de ambos os sexos (100 mulheres e 30 homens, com idades > ou = 65 (média 80±9 anos. Os pacientes foram avaliados através de exame clínico completo, rotina básica de sangue, radiografia simples de tórax, eletrocardiograma e ecocardiograma Doppler. Baseados na avaliação clínica e exames complementares, o uso do digital foi considerado adequado, questionável ou inadequado. RESULTADOS: Estavam em uso de digital 27,6% dos pacientes. A indicação foi considerada adequada em 36,1%, questionável em 11,1% e inadequada em 52,7%. CONCLUSÃO: Uma alta prevalência de prescrição do digital foi detectada nos idosos admitidos, sendo que a maior parte a adotava por razões consideradas inadequadas ou questionáveis. Devido ao risco aumentado de intoxicação digitálica nessa faixa etária, a droga deveria ser prescrita sob indicações mais criteriosas.

A camada de Descemet estava íntegra em 13% (n=38, enquanto eram encontrados fungos na superfície corneana de 45% (n=38 dos casos. CONCLUSÃO: A coleta do material poderá ser feita com sucesso mesmo depois de instalado o tratamento, entretanto, nas úlceras de córnea deve ser feito preferentemente a coleta de material com espátula para exame laboratorial e a microscopia confocal in vivo. A predominância das leveduras poderá ser devido a alterações morfológicas do fungo sofridas no tecido corneano. A penetração intraocular é facilitada por alterações da Camada de Descemet e pela própria capacidade do fungo de penetrar nos tecidos

    We tested whether dreams can anticipate a stressful exam and how failure/success in dreams affect next-day performance. We collected information on students' dreams during the night preceding the medical school entrance exam. Demographic, academic, sleep and dream characteristics were compared to the students' grades on the exam. Of the 719 respondents to the questionnaire (of 2324 total students), 60.4% dreamt of the exam during the night preceding it. Problems with the exam appeared in 78% of dreams and primarily involved being late and forgetting answers. Reporting a dream about the exam on the pre-exam night was associated with better performance on the exam (p=.01). The frequency of dreams concerning the exam during the first term predicted proportionally higher performance on the exam (R=0.1, p=.01). These results suggest that the negative anticipation of a stressful event in dreams is common and that this episodic simulation provides a cognitive gain. Copyright © 2014 Elsevier Inc.

    Lowrey, Kirsten Andrea

    2002-08-01

    The purpose of this research was to understand the different ways that students in a second-semester general chemistry course studied for an exam. I conducted this research using a qualitative methodology based on phenomenography (Marton, Hounsell & Entwistle, 1997). I conducted interviews before and after the first exam in CHM 116. I analyzed these interviews to describe students' studying styles. I analyzed the data from four students and presented this data as case studies. I completed a cross-case analysis that included data from five additional students. My results describe three different studying styles that were found: visual, self-regulated, and quantitative. Each studying style included a description of the characteristics associated with students who use the style, including epistemological beliefs, specific study behaviors, and affective response to learning chemistry. My implications discuss the relationship between this study and learning styles research, as well as other phenomenographic research. Suggestions are made for how to adapt teaching methods to take into account the different studying styles.

  7. Exams? Why worry? Interpreting anxiety as facilitative and stress appraisals.

    Strack, Juliane; Esteves, Francisco

    2015-01-01

    The present study examined why people differ in how they appraise the same stressful situation (an approaching exam). We explored whether interpreting anxiety as a facilitative emotion can affect the type of stress appraisal people make. One hundred and three undergraduate students took part in this study, which lasted for 10 days (leading up to an exam). The students completed a daily self-reported evaluation of anxiety, emotional exhaustion, and stress experienced. The findings suggest a process by which a stressful time can be experienced as motivating rather than threatening or emotionally exhausting. For example, interpreting anxiety as facilitative moderated the relationship between anxiety and stress appraisals. When interpreting their anxiety as facilitative, individuals showed a higher tendency to make challenge stress appraisals and a lower tendency to appraising the stressor as a threat. These differences were especially visible with high levels of anxiety. Furthermore, interpreting anxiety as facilitative was negatively associated with emotional exhaustion, but positively associated with the academic performance. These findings suggest an explanation why people differ in how they appraise the same stressor: how people interpret their anxiety may to a large part affect how they appraise difficult events and situations.

    Traditional teaching concepts in medical education do not take full advantage of current information technology. We aimed to objectively determine the impact of Tablet PC enhanced training on learning experience and MKSAP® (medical knowledge self-assessment program) exam performance. In this single center, prospective, controlled study final year medical students and medical residents doing an inpatient service rotation were alternatingly assigned to either the active test (Tablet PC with custom multimedia education software package) or traditional education (control) group, respectively. All completed an extensive questionnaire to collect their socio-demographic data, evaluate educational status, computer affinity and skills, problem solving, eLearning knowledge and self-rated medical knowledge. Both groups were MKSAP® tested at the beginning and the end of their rotation. The MKSAP® score at the final exam was the primary endpoint. Data of 55 (tablet n = 24, controls n = 31) male 36.4%, median age 28 years, 65.5% students, were evaluable. The mean MKSAP® score improved in the tablet PC (score Δ + 8 SD: 11), but not the control group (score Δ- 7, SD: 11), respectively. After adjustment for baseline score and confounders the Tablet PC group showed on average 11% better MKSAP® test results compared to the control group (plearning to their respective training programs.

    The objective of this paper is to estimate the values of doses, which are absorbed dose to the lens and thyroid in a dental X-ray. Thermoluminescence dosimeters were used, once they provide a reading of quality and effectiveness. This study was based on dental exams conducted in patients in order to estimate the dose that disperses to the lens of the eye and for the thyroid during an intraoral exam. Data collection took place in two institutions, one governmental, which had the device SELETRONIC 70X and other particular. This study showed that there is a considerable variation between the appliances. Using the appliance DABI 1070, there was a greater absorption of radiation in the right eye (values greater than 5 mGy) and a lower dose in the thyroid, and the Seletronic 70X presented an incidence of higher dose deposited in the skin and in other points there was a balance in the values. In the appliance SELETRONIC 70X, there was again a greater absorption of radiation in the right eye and a lower setting in the thyroid. The excessive dose, besides does not favor at all for the quality of radiograph, represents a risk for the patient who absorbs unnecessary and harmful radiation to the body

    2016-01-01

    Curricular issues of subject Applied Mathematics to Social Sciences are studied in relation to university entrance exams performed in several Spanish regions between 2009-2014. By using quantitative and qualitative analyses, it has been studied how these exams align with curriculum and how they produce a washback on curriculum and teachers' work. Additionally, one questionnaire about teachers' practices has been performed, in order to find out how the exams are influencing teaching methodology development. Main results obtained show that evaluation is producing a bias on the official curriculum, substantially simplifying the specific orientation that should guide applied mathematics. Furthermore, teachers' practices are influenced by the exams, and they usually approach their teaching methodology to the frequent types of exams. Also, slight differences among the teachers lead to distinguish two behavioral subgroups. Results can also be useful in an international context, because of the importance of standardized exit exams in OECD countries.

  12. Red vs. green: Does the exam booklet color matter in higher education summative evaluations? Not likely.

    Science.gov (United States)

    Arthur, Winfred; Cho, Inchul; Muñoz, Gonzalo J

    2016-10-01

    We examined the so-called "red effect" in the context of higher education summative exams under the premise that unlike the conditions or situations where this effect typically has been obtained, the totality of factors, such as higher motivation, familiarity with exam material, and more reliance on domain knowledge that characterize high-stakes testing such as those in operational educational settings, are likely to mitigate any color effects. Using three naturally occurring archival data sets in which students took exams on either red or green exam booklets, the results indicated that booklet color (red vs. green) did not affect exam performance. From a scientific perspective, the results suggest that color effects may be attenuated by factors that characterize high-stakes assessments, and from an applied perspective, they suggest that the choice of red vs. green exam booklets in higher education summative evaluations is likely not a concern.

    Temporomandibular joint is one of the most complicated joints of the body and plays an important role in the head and neck system. One of the factors affecting the temporomandibular joint and lead to temporomandibular disorder is anxiety with all the events causing it. The aim of this study was to determine a relationship between anxiety and temporomandibular disorders. In this prospective study, subjects were randomly selected. One hundred and thirty pre-university students in Isfahan were evaluated with Ketel's test of anxiety, exam stress test and temporomandibular disorder questionnaires. The evaluation was done in two stages 10 months and 1 month prior to the university entrance exam (Konkour), clinical assessments consisted of masticatory muscles and sternocleidomastoid muscle palpation, temporomandibular joint palpation for pain and noise and its movement, and mouth opening limitations. The Wilcoxon rank test and paired t-test were used to analyze the data and the P value under 0.05 was considered significant. The level of anxiety and occurrence of temporomandibular disorders were increased between two stages and had the highest level in the second stage. There was a significant increase between two stages (Ptemporomandibular disorders and anxiety between the two stages can suggest a possible relationship between anxiety and temporomandibular disorders. Therefore, the effect of anxiety in triggering temporomandibular disorder symptoms is probable.

    To validate The Johns Hopkins Adapted Cognitive Exam designed to assess and quantify cognition in critically ill patients. Prospective cohort study. Neurosciences, surgical, and medical intensive care units at The Johns Hopkins Hospital. One hundred six adult critically ill patients. One expert neurologic assessment and four measurements of the Adapted Cognitive Exam (all patients). Four measurements of the Folstein Mini-Mental State Examination in nonintubated patients only. Adapted Cognitive Exam and Mini-Mental State Examination were performed by 76 different raters. One hundred six patients were assessed, 46 intubated and 60 nonintubated, resulting in 424 Adapted Cognitive Exam and 240 Mini-Mental State Examination measurements. Criterion validity was assessed by comparing Adapted Cognitive Exam with a neurointensivist's assessment of cognitive status (ρ = 0.83, p validity was assessed by comparing Adapted Cognitive Exam with Mini-Mental State Examination in nonintubated patients (ρ = 0.81, p validity was assessed by surveying raters who used both the Adapted Cognitive Exam and Mini-Mental State Examination and indicated the Adapted Cognitive Exam was an accurate reflection of the patient's cognitive status, more sensitive a marker of cognition than the Mini-Mental State Examination, and easy to use. The Adapted Cognitive Exam demonstrated excellent interrater reliability (intraclass correlation coefficient = 0.997; 95% confidence interval 0.997-0.998) and interitem reliability of each of the five subscales of the Adapted Cognitive Exam and Mini-Mental State Examination (Cronbach's α: range for Adapted Cognitive Exam = 0.83-0.88; range for Mini-Mental State Examination = 0.72-0.81). The Adapted Cognitive Exam is the first valid and reliable examination for the assessment and quantification of cognition in critically ill patients. It provides a useful, objective tool that can be used by any member of the interdisciplinary critical care team to support

    It is almost universally agreed that more frequent formative assessment (homework, clicker questions, practice tests, etc.) leads to better student performance and generally better course evaluations. There is, however, only anecdotal evidence that the same would be true for more frequent summative assessment (exams). There maybe many arguments against giving more exams, including the general "pain" associated with examinations, as well as reduced teaching time, since classroom sessions are dedicated to exams rather than lecturing. We present evidence that increasing the number of exams in fact does lead to better learning success, less cheating and guessing on homework, and better student course evaluations.

  8. The University Entrance Exam that Diversified and the Problem

    Science.gov (United States)

    Kondo, Osamu

    The percentage of students who go on to universities or junior colleges is over fifty percent which is more than half of high school students. However the nation's birthrate is in decline and the total number of university-age children shows a declining tendency. Hence we cannot expect an increase in the number of applicants in the future. On the other hand, the number of universities has been increasing year by year. The competition among universities to survive is very fierce. The diversification of entrance examination is a symbol of this competition. By diversifying entrance exams, universities aimed at the quality of excellent students in the beginning. However, they have changed their direction to pursue the quantity of students. As of Today the entrance examination is losing its original starting function which means most or all applicants can enter universities. It is time all of the universities return to its starting line.

    Phantoms are simulating objects of structures of the human body and can be applied in the quality control and calibration of radiological equipment. The aim of the work is the development of a cardiac anthropomorphic phantom to assist in the elaboration of protocols of dynamic studies that demonstrate the blood circulation inside the cardiac chambers. For the construction of the phantom was used latex, applied in layers on an anatomical model of heart, having been constructed the cardiac chambers and atrioventricular valves. Cardiac chambers were connected to the cannulas for fluid injection and simulation of the circulatory system. The constructed phantom presents anthropomorphic characteristics and allows the circulation of the fluid without reflux, but the thickness of the catheters used does not yet allow flows of greater order of magnitude. This phantom has the potential to be used in the dynamic simulation of cardiac exams, contributing to the elaboration and adequacy of computed tomography protocols

    2018-03-01

    The purpose of this articl is to explore nursing students' experiences of dialogic group oral exams used in the assessment of a medical nursing course. We discuss a small-group, educator-facilitated exam (dialogue exam). The data were gathered in April 2015 via an online survey including open questions. The participants were nursing students (n = 58) at a University of Applied Sciences. The data were subjected to inductive content analysis. The results suggest that students' experiences of the dialogue exam can be represented by four themes: context bound dynamics, new shared understanding, verified competences and holistic nursing care. The students liked the dialogue exam format, preferring it to the traditional individual written exam. The prerequisite for successful use of the dialogue exam format is that candidates perceived the exam situation as safe. Students need to be given information about the schedule and assessment criteria beforehand and should have some experience of the format. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available ABSTRACTThe theory for studying the motivational potential of certain jobs – or job design – was developed for the context of an industrial society, one that is quite different from our current information society. This research proposes a device for discussing and analyzing the key characteristics of motivation referring to jobs, according to the theories of job design and to the information society context. This is a pragmatic research, which applies the Design Science research strategy. Based on an inventory and on content analysis of scientific research concerning job design – published in the twenty-first century in the electronic databases of PROQUEST and EBSCO scientific articles – the motivational characteristics that are associated to this theory were identified, structured and presented in the proposed device.RESUMOA teoria para estudo do potencial motivador de postos de trabalho, denominada job design, foi desenvolvida para o contexto da sociedade industrial, bastante distinta da atual sociedade da informação.

    Hysterosalpingography (HSG) is a relatively frequent radiological procedure, which is used to access and study the uterine cavity and the tubary permeability. The estimate of the radiation doses received by the patients, and of the associated risks, has become of great interest in recent years. The importance in evaluating the received doses becomes even higher when the gonads region is irradiated; as in the case of hysterosalpingography, where the patients are relatively young, existing a high probability of future pregnancy. In HSG procedure the physician stays beside the patient, being also exposed. The purpose of this study was to analyze, during HSG procedures, the exposition of patients, measuring the kerma-area (P{sub K,A}) product by using an ionization chamber of big area, to evaluate the doses received by the radiologist using thermoluminescent dosemeters and to evaluate the quality of image by means of qualitative methods. The results gotten during the accompaniment of 86 examinations had been the following ones: the average P{sub K,A} was 706 {+-} 388 cGy.cm{sup 2}, to an average exposition time of 2 {+-} 1 minutes. In order to optimize the exposure of patients and workers, the time of scopy and the number of images should be reduced, whenever it is possible. Due to the significant values of equivalent dose received by the lens, the use of plumbiferous eyeglasses is recommended. (author)

    Full Text Available Uma ampliação dos conceitos de consumo tem se deslocado na direção de processos sociais até agora não contemplados por categorias tradicionais. A presente revisão analisa a aplicação dos conceitos clássicos sobre consumismo às práticas recentemente identificadas no campo da saúde, como o fenômeno da cibercondria. O desafio teórico se refere à dificuldade de extrapolação das perspectivas econômicas do consumismo às questões do auto-cuidado no contexto das tecnologias de informação e comunicação (TICs. Procura-se compreender o fenômeno da mercadorização do cuidar-de-si sob o imperativo da auto-responsabilização em saúde. São identificadas e descritas as novas identidades consumidoras em vista das inauditas questões acerca dos aprimoramentos técnicos a modificar a natureza do auto-cuidado. Conclui-se que a saúde é consumida como vitalidade decomposta em artefatos de comercializar no contexto de uma nova bioeconomia - não mais ligada à idéia de emulação e posse, e sim a novas formas de perceber-se e cuidar-se perante múltiplos riscos e novas definições do que é ser humano.

  9. The new AP Physics exams: Integrating qualitative and quantitative reasoning

    Science.gov (United States)

    Elby, Andrew

    2015-04-01

    When physics instructors and education researchers emphasize the importance of integrating qualitative and quantitative reasoning in problem solving, they usually mean using those types of reasoning serially and separately: first students should analyze the physical situation qualitatively/conceptually to figure out the relevant equations, then they should process those equations quantitatively to generate a solution, and finally they should use qualitative reasoning to check that answer for plausibility (Heller, Keith, & Anderson, 1992). The new AP Physics 1 and 2 exams will, of course, reward this approach to problem solving. But one kind of free response question will demand and reward a further integration of qualitative and quantitative reasoning, namely mathematical modeling and sense-making--inventing new equations to capture a physical situation and focusing on proportionalities, inverse proportionalities, and other functional relations to infer what the equation ``says'' about the physical world. In this talk, I discuss examples of these qualitative-quantitative translation questions, highlighting how they differ from both standard quantitative and standard qualitative questions. I then discuss the kinds of modeling activities that can help AP and college students develop these skills and habits of mind.

    2014-01-01

    This work aims to investigate the dose descriptor, volumetric Computed Tomography Dose Index (CTDI), a pediatric patients sample undergoing to skull CT, comparing the results with the diagnostic reference levels of the literature. Were collected volumetric CTDI values of all skull CT exams performed retrospectively in children of 0-10 years of age in a period of 12 months in a large hospital size. Patients, in a total of 103, were divided into four groups, where the criterion of separation used was age, trying to use the same division used in international references dose descriptors. In all acquisitions we used the pediatric protocol and the Automatic Exposure Control (AEC) available on the equipment. The CDTI values, with and without the use of AEC for pediatric studies, were compared. There was a reduction of approximately 100% in the absorbed dose value due to the use of the AEC. From the data collected and analyzed in this work, it is concluded that the use of dose reduction systems is relevant, such as the Care Dose, to maintain volumetric CTDI values within the reference levels. Also it is important the observation of range of children age to the appropriate choice of parameters used in the test protocol. The values obtained are according to the diagnostic reference levels from the literature

    Full Text Available Auricular acupuncture (AA is effective in the treatment of preoperative anxiety. The aim was to investigate whether AA can reduce exam anxiety as compared to placebo and no intervention. Forty-four medical students were randomized to receive AA, placebo, or no intervention in a crossover manner and subsequently completed three comparable oral anatomy exams with an interval of 1 month between the exams/interventions. AA was applied using indwelling fixed needles bilaterally at points MA-IC1, MA-TF1, MA-SC, MA-AT1 and MA-TG one day prior to each exam. Placebo needles were used as control. Levels of anxiety were measured using a visual analogue scale before and after each intervention as well as before each exam. Additional measures included the State-Trait-Anxiety Inventory, duration of sleep at night, blood pressure, heart rate and the extent of participant blinding. All included participants finished the study. Anxiety levels were reduced after AA and placebo intervention compared to baseline and the no intervention condition (p < 0.003. AA was better at reducing anxiety than placebo in the evening before the exam (p = 0.018. Participants were able to distinguish between AA and placebo intervention. Both AA and placebo interventions reduced exam anxiety in medical students. The superiority of AA over placebo may be due to insufficient blinding of participants.

  17. Multiple-Choice Exams: An Obstacle for Higher-Level Thinking in Introductory Science Classes

    Science.gov (United States)

    Stanger-Hall, Kathrin F.

    2012-01-01

    Learning science requires higher-level (critical) thinking skills that need to be practiced in science classes. This study tested the effect of exam format on critical-thinking skills. Multiple-choice (MC) testing is common in introductory science courses, and students in these classes tend to associate memorization with MC questions and may not see the need to modify their study strategies for critical thinking, because the MC exam format has not changed. To test the effect of exam format, I used two sections of an introductory biology class. One section was assessed with exams in the traditional MC format, the other section was assessed with both MC and constructed-response (CR) questions. The mixed exam format was correlated with significantly more cognitively active study behaviors and a significantly better performance on the cumulative final exam (after accounting for grade point average and gender). There was also less gender-bias in the CR answers. This suggests that the MC-only exam format indeed hinders critical thinking in introductory science classes. Introducing CR questions encouraged students to learn more and to be better critical thinkers and reduced gender bias. However, student resistance increased as students adjusted their perceptions of their own critical-thinking abilities. PMID:22949426

    The selection of the contrast agent used during fluoroscopic exams is an important clinical decision. The purpose of this article is to document the usage of a nonionic, water-soluble contrast (iohexol) and barium contrast in adult patients undergoing fluoroscopic exams of the pharynx and/or esophagus and provide clinical indications for the use of each. For 1 year, data were collected on the use of iohexol and barium during fluoroscopic exams. The contrast agent used was selected by the speech language pathologist (SLP) or the radiologist based on the exam's indications. A total of 1,978 fluoroscopic exams were completed in the 12-month period of documentation. Of these exams, 60.6 % were completed for medical reasons and 39.4 % for surgical reasons. Fifty-five percent of the exams were performed jointly by a SLP and a radiologist and 45 % were performed by a radiologist alone. Aspiration was present in 22 % of the exams, vestibular penetration occurred in 38 %, extraluminal leakage of contrast was observed in 4.6 %, and both aspiration and leakage were seen in 1 % of the exams. In cases with aspiration, iohexol was used alone in 8 %, iohexol and barium were both used in 45 %, and barium was used alone in 47 %. In cases with extraluminal leakage, iohexol was used alone in 58 %, iohexol and barium were both used in 31 %, and barium was used alone in 11 %. No adverse effects were seen with the use of iohexol. When barium was used in cases of aspiration and extraluminal leakage, the amount of aspirated barium was small and the extraluminal barium in the instances of leakage was small. Iohexol is a useful screening contrast agent and can safely provide information, and its use reduces the risk of aspiration and the chance of leakage of large amounts of barium.

    Khansari, Parto S; Coyne, Leanne

    The study investigates students' perceptions of the value of implementing a team exam to enhance learning prior to a summative assessment. Team exams are similar to midterm exams, except that answering questions is a team effort. Data was collected from second year pharmacy students at California Northstate University College of Pharmacy (CNUCOP) through a self-administered online survey. The survey questions included closed-ended questions to evaluate students' perception on preparedness for a summative assessment and to rank advantages and disadvantages of the team exams. Of the 40 students who completed the survey (38% response rate), 100% of participants agreed that having a team exam prior to a major exam made them feel more prepared for a major summative exam. Ninety-seven percent of students believed that the team exam helped them to identify gaps in their knowledge and 85% agreed that taking a team exam reinforced their knowledge by teaching other students. The survey results did not identify any major disadvantages to holding a team exam. Students perceived that taking a team exam prior to a midterm exam is an effective approach to review the course contents and identify areas of improvement. Copyright © 2017.

Houve uma ocorrência significativa do feocromocitoma adrenal (13% de todos os tumores. Papilomatose representou apenas 3% de todos os tumores. Como papilomas são comuns em bovinos, seu baixo número nesse estudo pode ser explicado pelo fato de que eles não são usualmente diagnosticados no exame post mortem (quando o couro já foi retirado da carcaça, mas sim no exame ante mortem, como ocorreu na maioria dos casos deste estudo. Tumores encontrados com menor frequência (cada um perfazendo entre 1.5 e 3% de todos os tumores incluíram adenocarcinoma apócrino misto da cauda, adenocarcinoma mamário, adenocarcinoma uterino, carcinoma de células renais, fibroma interdigital, hemangiossarcoma, leiomioma uterino, lipoma, lipossarcoma, mesotelioma, neurofibroma, tumor de células da granulosa, tumor estromal gastrointestinal, tumores hepáticos, tumores melanocíticos, e tumores pulmonares primários. Pretende-se que os resultados dessa pesquisa possam ajudar na identificação das lesões na inspeção oficial em matadouros frigoríficos.

    Full Text Available RESUMO O presente trabalho analisa as discussões promovidas sobre o tema Inteligência Competitiva (IC no período de 1984 a 2013. Organizado na forma de pesquisa métrica, foram analisados dados bibliográficos de 3.453 artigos indexados na base de dados Scopus, identificando os assuntos que receberam maior atenção por parte de seus autores, assim como sua distribuição geográfica e temporal. Observou-se uma mudança natural nas discussões, que inicialmente concentravam-se na busca do entendimento conceitual e da justificativa da existência da IC, para um maior foco em artefatos tecnológicos capazes de proporcionar melhoramentos na sua prática. A discussão sobre ética, por sua vez, perpassa a literatura sobre IC durante todo o período estudado. Verificou-se ainda que a produção na área de Gestão tem recebido grande atenção em todas as regiões geográficas, seguida da área de Planejamento Estratégico, que apenas perde a segunda posição na Ásia, onde a Modelagem Matemática tem sido o principal tópico.

    Full Text Available Saber lidar com telas digitais e novos artefatos envolve várias habilidades e diferentes inteligências. Nesse contexto, o presente trabalho tem como objetivo identificar o exercício das múltiplas inteligências nas possibilidades educativas de uso dos jogos digitais. Para tanto, realizou-se uma pesquisa exploratória de abordagem quantitativa, por meio da aplicação de um questionário com 58 alunos do Curso de Extensão em Formação Continuada em Conselhos Escolares para avaliação da experiência de uso de um jogo educativo previsto como atividade. Os resultados revelaram, segundo a percepção dos cursistas, que a inteligência relacionada à matemática e o raciocínio lógico foi a mais utilizada, seguida pela inteligência existencial, a abstração e inteligência espacial e a coordenação motora. Este reconhecimento do exercício das múltiplas inteligências na interação com jogos digitais reforça seu potencial educativo e as diferentes possibilidades pedagógicas de uso.

    Full Text Available Continuous assessment aims to enhance student learning and understanding of a subject and so achieve better educational outcomes. We investigated how continuous assessment grades affected final exam grades. Using a dataset for six academic post-Bologna Process years (2009-2015 for a first-year undergraduate microeconomics course offered at a Spanish public university, we examined conditional dependence between continuous assessment and final exam grades. Our results would indicate a limited contribution of continuous assessment results to final exam results: the probability of the final exam performance improving on the continuous assessment grade was lower than the probability of the opposite occurring. A consistent exception, however, was students who obtained an A grade for continuous assessment. Our results would cast some doubt on the beneficial effects of continuous assessment advocated by the Bologna Process.

    Full Text Available The current study examined the effect of high school graduation exams on states' graduation rates, states' aggregated SAT scores, and individual students' SAT scores. Three data sources were used: One source identified states requiring a standardized test for graduation; the NCES provided state aggregated data on graduation rates for the class of 2002; and the College Board provided its 2001 SAT database for all test-takers. After controlling for students' demographic characteristics (e.g., race, family education and income, GPA and class rank, regression analyses revealed that states requiring graduation exams had lower graduation rates and lower SAT scores. Individually, students from states requiring a graduation exam performed more poorly on the SAT than did students from states not requiring an exam. The impact of high stakes tests' on students' motivation to stay in school and on the teaching of critical thinking skills (tested by the SAT are discussed.

In addition, we examined the relationship between exam performance and the number of clinical tutors per student.Materials and methods: A retrospective review of the logbooks of first and third clinical year medical students at the Faculty of Medicine, Kuwait University, was undertaken during their surgery rotation during the academic year 2012–2013.Results: Logbooks of 184 students were reviewed and analyzed. There were 92 and 93 students in the first and third clinical years, respectively. We did not identify any correlation between the number of clinical encounters and clinical exam or multiple-choice exam scores; however, there was an inverse relationship between the number of clinical tutors encountered during a rotation and clinical exam scores.Conclusion: Overall, there was no correlation between the volume of self-reported clinical encounters and exam scores. Furthermore, an inverse correlation between the number of clinical tutors encountered and clinical exam scores was detected.

  2. Integrity of Disposable Nitrile Exam Gloves Exposed to Simulated Movement

    Phalen, Robert N.; Wong, Weng Kee

    2011-01-01

    Every year, millions of health care, first responder, and industry workers are exposed to chemical and biological hazards. Disposable nitrile gloves are a common choice as both a chemical and physical barrier to these hazards, especially as an alternative to natural latex gloves. However, glove selection is complicated by the availability of several types or formulations of nitrile gloves, such as low-modulus, medical-grade, low-filler, and cleanroom products. This study evaluated the influence of simulated movement on the physical integrity (i.e., holes) of different nitrile exam glove brands and types. Thirty glove products were evaluated out-of-box and after exposure to simulated whole-glove movement for 2 hr. In lieu of the traditional 1-L water-leak test, a modified water-leak test, standardized to detect a 0.15 ± 0.05 mm hole in different regions of the glove, was developed. A specialized air inflation method simulated bidirectional stretching and whole-glove movement. A worst-case scenario with maximum stretching was evaluated. On average, movement did not have a significant effect on glove integrity (chi-square; p=0.068). The average effect was less than 1% between no movement (1.5%) and movement (2.1%) exposures. However, there was significant variability in glove integrity between different glove types (p ≤ 0.05). Cleanroom gloves, on average, had the highest percentage of leaks, and 50% failed the water-leak test. Low-modulus and medical-grade gloves had the lowest percentages of leaks, and no products failed the water-leak test. Variability in polymer formulation was suspected to account for the observed discrepancies, as well as the inability of the traditional 1-L water-leak test to detect holes in finger/thumb regions. Unexpectedly, greater than 80% of the glove defects were observed in the finger and thumb regions. It is recommended that existing water-leak tests be re-evaluated and standardized to account for product variability. PMID:21476169

    The introduction of computer-based testing in high-stakes examining in higher education is developing rather slowly due to institutional barriers (the need of extra facilities, ensuring test security) and teacher and student acceptance. From the existing literature it is unclear whether computer-based exams will result in similar results as paper-based exams and whether student acceptance can change as a result of administering computer-based exams. In this study, we compared results from a computer-based and paper-based exam in a sample of psychology students and found no differences in total scores across the two modes. Furthermore, we investigated student acceptance and change in acceptance of computer-based examining. After taking the computer-based exam, fifty percent of the students preferred paper-and-pencil exams over computer-based exams and about a quarter preferred a computer-based exam. We conclude that computer-based exam total scores are similar as paper-based exam scores, but that for the acceptance of high-stakes computer-based exams it is important that students practice and get familiar with this new mode of test administration.

    Although many educational institutions allow students to resit exams, a recently proposed mathematical model suggests that this could lead to a dramatic reduction in study-time investment, especially in rational students. In the current study, we present a modification of this model in which we included some well-justified assumptions about learning and performance on multiple-choice tests, and we tested its predictions in two experiments in which participants were asked to invest fictional study time for a fictional exam. Consistent with our model, the prospect of a resit exam was found to promote lower investments of study time for a first exam and this effect was stronger for participants scoring higher on the cognitive reflection test. We also found that the negative effect of resit exams on study-time investment was attenuated when access to the resit was made uncertain by making it probabilistic or dependent on obtaining a minimal, non-passing grade for the first attempt. Taken together, these results suggest that offering students resit exams may compromise the achievement of learning goals, and they raise the more general implication that second chances promote risky behavior.

    The latest report by the National Crime Records Bureau has positioned Tamil Nadu as the Indian state with highest suicide rate. At least in part, this is happening due to exam pressure among adolescents, emphasizing the imperative need to understand the pattern of anxiety and various factors contributing to it among students. The present study was conducted to analyze the level of state anxiety among board exam attending school students in Tamil Nadu, India. A group of 100 students containing 50 boys and 50 girls from 10th and 12th grades participated in the study and their state anxiety before board exams was measured by Westside Test Anxiety Scale. We found that all board exam going students had increased level of anxiety, which was particularly higher among boys and 12th standard board exam going students. Analysis of various demographic variables showed that students from nuclear families presented higher anxiety levels compared to their desired competitive group. Overall, our results showing the prevalence of state anxiety among board exam going students in Tamil Nadu, India, support the recent attempt taken by Tamil Nadu government to improve student's academic performance in a healthier manner by appointing psychologists in all government schools.

    The ExaMe system for the evaluation of targeted knowledge has been in development since 1998. The new features of the ExaMe system are introduced in this paper. Especially, the new three-layer architecture is described. Besides the system itself, the properties of fixed tests in the ExaMe system are studied. In special detail, the reliability of the fixed tests is discussed. The theory background is explained and some limitations of the reliability are pointed out. Three characteristics used for estimation of reliability of educational tests are discussed: Cronbach's alpha, standardized item alpha and split half coefficient. The relation between these characteristics and reliability and between characteristics themselves is investigated. In more detail, the properties of Cronbach's alpha, the characteristics mostly used for the estimation of reliability, are discussed. A confidence interval is introduced for the characteristics. Since 2000, the serviceability of the ExaMe evaluation system as the supporting evaluation tool has been repeatedly shown at the courses of Ph.D. studies in biomedical informatics at Charles University in Prague. The ExaMe system also opens new possibilities for self-evaluation and distance learning, especially when connected with electronic books on the Internet. The estimation of reliability of tests contains some limitations. Keeping them in mind, we can still get some information about the quality of certain educational tests. Therefore, the estimation of reliability of the fixed tests is implemented in the ExaMe system.

    Academic exam stress is known to compromise sleep quality and alter drug consumption in university students. Here we evaluated if sleeping problems and changes in legal drug consumption during exam stress are interrelated. We used the Pittsburgh Sleep Quality Index (PSQI) to survey sleep quality before, during, and after an academic exam period in 150 university students in a longitudinal questionnaire study. Self-reports of alcohol, caffeine, and nicotine consumption were obtained. The Perceived Stress Questionnaire (PSQ-20) was used as a measure of stress. Sleep quality and alcohol consumption significantly decreased, while perceived stress and caffeine consumption significantly increased during the exam period. No significant change in nicotine consumption was observed. In particular, students shortened their time in bed and showed symptoms of insomnia. Mixed model analysis indicated that sex, age, health status, as well as the amounts of alcohol and caffeine consumed had no significant influence on global sleep quality. The amount of nicotine consumed and perceived stress were identified as significant predictors of diminished sleep quality. Nicotine consumption had a small-to-very-small effect on sleep quality; perceived stress had a small-to-moderate effect. In conclusion, diminished sleep quality during exam periods was mainly predicted by perceived stress, while legal drug consumption played a minor role. Exam periods may pose an interesting model for the study of stress-induced sleeping problems and their mechanisms.

    Full Text Available PURPOSE: We tested the role of frozen section examination of the cone specimen in the evaluation of the resection margin status and to rule out invasion in patients with high-grade cervical intraepithelial neoplasia. METHODS: Twenty-five patients with cervical intraepithelial neoplasia underwent conization followed by frozen section examination and planned hysterectomy. The results of the definitive paraffin exam were compared with frozen section examination. RESULTS: In the evaluation of the margins by frozen section examination, 16 patients (64% had positive cone margins and 9 (36% had negative margins. The definitive paraffin examination of margin status was concordant in all the cases. Intraoperative diagnosis of invasion was made in 5 cases, and 1 of these was microinvasive. Among the remaining 20 cases, we detected 2 additional microinvasive carcinomas after paraffin study, so the diagnosis of the frozen section examination was concordant with the paraffin sections in 23/25 cases (92%. Two cases of microinvasive carcinoma were diagnosed as cervical intraepithelial neoplasia by frozen section examination and had less than 2 mm stromal invasion. CONCLUSIONS: In high-grade cervical intraepithelial neoplasia, frozen section examination can provide immediate and precise evaluation of the cone margin status in high-grade cervical intraepithelial neoplasia. It can identify frank invasion and permit adequate treatment in a one-stage procedure. In early microinvasive disease, frozen section examination fails to detect the area of invasion but reliably detects clear resection margins.OBJETIVOS: Foi avaliado o papel do exame intra-operatório de congelação no diagnóstico de invasão e no estado das margens cirúrgicas em pacientes com neoplasia intra-epitelial de alto grau. CASUÍSTICA E MÉTODO: Vinte e cinco pacientes com neoplasia intra-epitelial de alto grau foram submetidas a conização cervical seguida de histerectomia. O resultado do exame

    Pre-exam anxiety syndrome is a common condition occurring in pre-exam students and directly affects their examination performance and physical state. Wrist-ankle acupuncture has significant therapeutic effects in treating mental disorders and may also relieve the symptoms of pre-exam anxiety syndrome. To assess the therapeutic effect of wrist-ankle acupuncture on pre-exam anxiety syndrome. A total of 60 students who met the inclusion criteria of pre-exam anxiety syndrome were enrolled from a university in Shanghai and they were randomly divided into treatment group and control group. There were 30 cases in each group, and no case failed to follow-up. In the treatment group, wrist-ankle acupuncture was adopted to point upper 1 bilaterally (impression between flexor carpi ulnaris tendon and ulnar margin), and there was no requirement for Deqi (arrival of qi). In the control group, sham acupuncture was adopted. The treatment was applied 3 times totally in both groups one week before the exam, once every other day, each time with the needles retained for 30 min. The therapeutic effects were compared between two groups. Before and after 3 treatments, Sarason Test Anxiety Scale (TAS) and Expectation and Treatment Credibility Scale (ETCS) were measured and evaluated. The therapeutic effect experienced by the treatment group was better than that of the control group (PETCS before treatment between the two groups. The scores of TAS after treatment in two groups were higher than those before treatment (PETCS than those in the control group (P<0.05, P<0.01). No adverse reaction was reported. Wrist-ankle acupuncture can relieve the symptoms of pre-exam anxiety syndrome significantly, and this therapy is highly safe.

    Full Text Available Fluorescence<em> em>>in situ em>hybridization (FISH assay is considered the “gold standard” in evaluating <em>HER2/neu (HER2em> gene status. However, FISH detection is costly and time consuming. Thus, we established nuclei microarray with extracted intact nuclei from paraffin embedded breast cancer tissues for FISH detection. The nuclei microarray FISH (NMFISH technology serves as a useful platform for analyzing <em>HER2em> gene/chromosome 17 centromere ratio. We examined <em>HER2em> gene status in 152 cases of invasive ductal carcinomas of the breast that were resected surgically with FISH and NMFISH. <em>HER2em> gene amplification status was classified according to the guidelines of the American Society of Clinical Oncology and College of American Pathologists (ASCO/CAP. Comparison of the cut-off values for <em>HER2em>/chromosome 17 centromere copy number ratio obtained by NMFISH and FISH showed that there was almost perfect agreement between the two methods (κ coefficient 0.920. The results of the two methods were almost consistent for the evaluation of <em>HER2em> gene counts. The present study proved that NMFISH is comparable with FISH for evaluating <em>HER2em> gene status. The use of nuclei microarray technology is highly efficient, time and reagent conserving and inexpensive.

    One of the frequent questions in obstetric practice is to determine placental vascular changes that may account for abnormal Doppler flow velocity alterations in maternal uterine vessels from women and fetuses without pregnancy pathology. A retrospective morphometric study was realized using 27 placentas from patients submitted for Doppler flow velocity exam during pregnancy. The placentas were morphologically examined using hematoxylin-eosin staining. Measurements of villi were made with the use of a video camera coupled to a common light microscope and a computer with automatic image analyzing software. Of the 27 placentas, 13 (48%) were of patients showing unaltered Doppler and 14 (52%) showing altered Doppler. The number of stem villi vessels was significantly larger in the placentas of patients with Doppler exam alterations (P = 0.003). This group also presented greater stem villi vessel thickness, although without significant difference. The number of intermediary and terminal villi vessels was greater in the placentas of patients with altered Doppler exams (P < 0.001), and a greater terminal villi area was observed in these cases (P < 0.001). The morphological proof that uterine artery Doppler flow velocity exam alterations are associated with placental vascular alterations demonstrates the importance of this exam during prenatal care, even in the absence of maternal-fetal alterations.

    [Purpose] The purpose of this study was to examine the relationships between manual dexterity and the Unified Parkinson's Disease Rating Scale-Motor Exam as a clinical tool for quantifying upper extremity function in persons with Parkinson's disease. [Subjects and Methods] Thirty-two persons with idiopathic Parkinson's disease participated in this study. This study measured two clinical outcomes, the box-and-block test and the Unified Parkinson's Disease Rating Scale-Motor Exam, to investigate the relationships between manual dexterity and the Unified Parkinson's Disease Rating Scale-Motor Exam. [Results] The box-and-block test on the more affected side was positive relationship with the box-and-block test on the less affected side. The Unified Parkinson's Disease Rating Scale-motor exam score had a negative correlation with the box-and-block test results for both sides. [Conclusion] A positive association was noted between manual dexterity and motor function in patients with idiopathic Parkinson disease. The results of this study suggest that the box-and-block test and the Unified Parkinson's Disease Rating Scale-Motor Exam are good clinical measures that quantify upper extremity function and are necessary for the accurate evaluation of patients and to plan intervention strategies.

    Full Text Available Learners studying for exams sometimes show a lack of awareness in their abilities as tested through the framework of that exam. Instead, such learners focus on the score obtained in exams, and exam preparation includes using textbooks, online materials and timed use of past papers. The purpose of exam-focused flexible self-directed learning modules (FSDLMs at Kanda University of International Studies have been designed to address this by developing learners’ ability to identify their strengths and weaknesses, to make informed decisions about their own learning, and to improve their test-taking skills. Each FSDLM has at its core a diagnostic for learners to use for self-evaluation, often with guidance from a learning advisor. This process leads to the setting of clear goals and the development and implementation of an individual learning plan through a variety of dialogues. Learners have the potential to transfer this skill beyond examination preparation to other areas of learning. In other words, learners’ awareness of needs analysis, planning, implementation and evaluation is fostered with a view to developing their language learning ability within and beyond this module.

    The Indonesian Physics national-exams are end-of-course summative assessments that could be utilized to support the assessment for learning in physics educations. This paper discusses the development and evaluation of a testlet generator based on a re-engineering of Indonesian physics national exams. The exam problems were dissected and decomposed into testlets revealing the deeper understanding of the underlying physical concepts by inserting a qualitative question and its scientific reasoning question. A template-based generator was built to facilitate teachers in generating testlet variants that would be more conform to students' scientific attitude development than their original simple multiple-choice formats. The testlet generator was built using open source software technologies and was evaluated focusing on the black-box testing by exploring the generator's execution, inputs and outputs. The results showed the correctly-performed functionalities of the developed testlet generator in validating inputs, generating testlet variants, and accommodating polytomous item characteristics.

    Full Text Available We introduced voluntary wiki-based exercises to a long-running cognitive psychology course, part of the core curriculum for an undergraduate degree in psychology. Over 2 yearly cohorts, students who used the wiki more also scored higher on the final written exam. Using regression analysis, it is possible to account for students’ tendency to score well on other psychology exams, thus statistically removing some obvious candidate third factors, such as general talent or enthusiasm for psychology, which might drive this correlation. Such an analysis shows that both high- and low-grading students who used the wiki got higher scores on the final exam, with engaged wiki users scoring an average of an extra 5 percentage points. We offer an interpretation of the mechanisms of action in terms of the psychological literature on learning and memory.

    The present study aims at analyzing the meanings attributed to the digital rectal exam, seeking to problematize questions underlying the masculine discourse on the basis of aspects of the hegemonic masculinity model. Semi-structured interviews were held with 28 men in the city of Rio de Janeiro, in 2004. Among the main results is the idea that the digital rectal exam is something that violates an interdicted space, something that compromises the current understanding of masculinity, shall say, the digital rectal exam does not only affect the prostate, it also affects the masculinity, puts it to shame. We conclude that for understanding and problematizing the questions related to the prostate cancer prevention in special, and to the question of taking care of oneself from the masculine perspective in general, we need to consider the structural and symbolic aspects that underlie these questions.

    Medication administration is an important task of registered nurses. According to previous studies, nurses lack theoretical knowledge and drug calculation skills and knowledge-based mistakes do occur in clinical practice. Finnish health care organizations started to develop a systematic verification processes for medication competence at the end of the last decade. No studies have yet been made of nurses' theoretical knowledge and drug calculation skills according to these online exams. The aim of this study was to describe the medication competence of Finnish nurses according to theoretical and drug calculation exams. A descriptive correlation design was adopted. Participants and settings All nurses who participated in the online exam in three Finnish hospitals between 1.1.2009 and 31.05.2014 were selected to the study (n=2479). Quantitative methods like Pearson's chi-squared tests, analysis of variance (ANOVA) with post hoc Tukey tests and Pearson's correlation coefficient were used to test the existence of relationships between dependent and independent variables. The majority of nurses mastered the theoretical knowledge needed in medication administration, but 5% of the nurses struggled with passing the drug calculation exam. Theoretical knowledge and drug calculation skills were better in acute care units than in the other units and younger nurses achieved better results in both exams than their older colleagues. The differences found in this study were statistically significant, but not high. Nevertheless, even the tiniest deficiency in theoretical knowledge and drug calculation skills should be focused on. It is important to identify the nurses who struggle in the exams and to plan targeted educational interventions for supporting them. The next step is to study if verification of medication competence has an effect on patient safety. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available We report an 18-month-old male who presented with fever and nonspecific symptoms. He was evaluated for multiple differential diagnoses including Kawasaki disease and JIA and received treatment for them. After he was readmitted, tularemia was considered based on the physical exam finding of an ulcer on the scalp and enlarged lymph nodes. Tularemia titers were positive, and the patient was given the appropriate antibiotic and was discharged home. Follow-up of the patient showed complete resolution of symptoms. This is a case that demonstrates the importance of physical exam in identifying rare diseases presenting with common signs and symptoms.

    Full Text Available The Medical Council of Canada has set new eligibility criteria for examinations that are required in order to apply to postgraduate training. This is to facilitate the establishment of the National Assessment Collaboration Objective Structured Clinical Examination. These changes result in increased hardships on Canadians studying abroad who are wishing to apply for postgraduate training in Canada. While these exams are crucial to protect medical standards and the quality of healthcare in Canada, slight modifications of the examination timelines may alleviate some of the burdens caused by these exams.

    Beta-blockers relieve the autonomic symptoms of exam-related anxiety and may be beneficial in exam-related and performance anxiety, but knowledge on related psychiatric outcomes is unknown. We hypothesized that beta-blocker therapy for exam-related anxiety identifies young students at risk of later psychiatric events. Using Danish nationwide administrative registries, we studied healthy students aged 14-30 years (1996-2012) with a first-time claimed prescription for a beta-blocker during the exam period (May-June); students who were prescribed a beta-blocker for medical reasons were excluded. We matched these students on age, sex, and time of year to healthy and study active controls with no use of beta-blockers. Risk of incident use of antidepressants, incident use of other psychotropic medications, and suicide attempts was examined by cumulative incidence curves for unadjusted associations and multivariable cause-specific Cox proportional hazard analyses for adjusted hazard ratios (HRs). We identified 12,147 healthy students with exam-related beta-blocker use and 12,147 matched healthy students with no current or prior use of beta-blockers (median age, 19 years; 80.3% women). Among all healthy students, 0.14% had a first-time prescription for a beta-blocker during the exam period with the highest proportion among students aged 19 years (0.39%). Eighty-one percent of the students filled only that single prescription for a beta-blocker during follow-up. During follow-up, 2225 (18.3%) beta-blocker users and 1400 (11.5%) nonbeta-blocker users were prescribed an antidepressant (p beta-blocker users and 658 (5.4%) nonbeta-blocker users were prescribed a psychotropic drug (p beta-blocker users and 6 (0.05%) nonbeta-blocker users attempted suicide (p = 0.03). Exam-related beta-blocker use was associated with an increased risk of antidepressant use (adjusted HRs, 1.68 [95% confidence intervals (CIs), 1.57-1.79], p beta-blockers during the exam period was

    Full Text Available O artigo é uma reflexão teórica que faz parte de um estudo denominado Em Defesa da Sociedade: a invenção dos Cuidados Paliativos. Para articular tal discussão, utilizamos o manual de Cuidados Paliativos, publicado no ano de 2007 pela Organização Mundial da Saúde (OMS, entendendo-o como parte de um artefato capaz de produzir subjetividades e governar condutas. Nesse sentido, pretendemos descobrir como os discursos sobre os Cuidados Paliativos se articulam e efetuam a invenção de uma nova disciplina que funcionaria como uma estratégia biopolítica para defender a sociedade. A partir da análise textual do discurso instituído pelo manual, com o auxílio do referencial dos Estudos Culturais e sob a inspiração dos escritos de Michel Foucault, articulamos uma das possíveis leituras deste guia. Desta maneira observamos a (reorganização e a (reinvenção de uma disciplina que investe na subjetividade dos indivíduos constituindo aparatos de verdade que regulam e governam a população.

    2014-12-01

    Full Text Available O objetivo deste artigo é oferecer uma análise da produção científica sobre sustentabilidade em conjuntos de artigos das áreas de ecologia, economia, sociologia e antropologia, a partir de quinze dentre os vinte e cinco artigos mais citados no sítio ISI -Web of Science em cada ciência, entre 1990 e 2010. Observaram-se os arranjos conceituais que configuram o termo nessas ciências, para compreender como elas abordam os hibridismos - as interfaces "humanos/não humanos" e "ciência/política"- presentes nos discursos sobre sustentabilidade. A análise concentrou-se na tensão entre disciplinaridade e interdisciplinaridade no contexto de estabelecimento da relação entre artefato científico e propositividade política. Para tanto, a leitura orientou-se por três dimensões da discursividade presentes nos artigos: as concepções de interação entre humanos e não humanos; as definições de risco e ameaça; e as estratégias de enfrentamento das questões de sustentabilidade. Essa tríade fundamentou-se na teoria da modernização reflexiva e nos estudos sociais da ciência. Observaram-se, nos quatro conjuntos, dois campos de possibilidades de articulação interdisciplinar denominados "ecologização" e "politização", ambos orientados por um sentido de "interdisciplinaridade por continuidade".

    2005-01-01

    During the last century, the creation and implementation of board certification has had a powerful impact on the medical community. Board certification has helped to shape the scope and practice of medical professionals and the care they provide, as well as to influence the way the health insurance industry sets standards for reimbursement. One profession that offers board certification to its members is medical dosimetry. The Medical Dosimetrist Certification Board exam has been administered since 1988 and its content covers a broad spectrum of information from the radiation therapy sciences. The exam has strict application requirements and is rather difficult to pass. Those who pass the exam can then call themselves Certified Medical Dosimetrists. For data purposes of this study, several members of the dosimetry community were solicited to participate in a survey regarding the exam's content and history, and to provide relevant statistical data. Currently 2,177 medical dosimetrists are board certified, with an additional 1,500 estimated to be working without certification. Although board certification is not currently required to practice medical dosimetry, new legislation known as the CARE Bill could change this. The CARE Bill, if passed, would mandate nationwide compulsory licensure and/or certification for medical dosimetrists and other medical professionals who want to work in radiation-related health care. Health maintenance organizations and other insurance carriers may likewise require certification for reimbursement purposes

    We studied gains in student learning over eight semesters in which an introductory biology course curriculum was changed to include optional verbal final exams (VFs). Students could opt to demonstrate their mastery of course material via structured oral exams with the professor. In a quantitative assessment of cell biology content knowledge, students who passed the VF outscored their peers on the medical assessment test (MAT), an exam built with 40 Medical College Admissions Test (MCAT) questions (66.4% [n = 160] and 62% [n = 285], respectively; p students performed better on MCAT questions in all topic categories tested; the greatest gain occurred on the topic of cellular respiration. Because the VF focused on a conceptually parallel topic, photosynthesis, there may have been authentic knowledge transfer. In longitudinal tracking studies, passing the VF also correlated with higher performance in a range of upper-level science courses, with greatest significance in physiology, biochemistry, and organic chemistry. Participation had a wide range but not equal representation in academic standing, gender, and ethnicity. Yet students nearly unanimously (92%) valued the option. Our findings suggest oral exams at the introductory level may allow instructors to assess and aid students striving to achieve higher-level learning. PMID:24006399

    To explore the use of over the counter (OTC) medicines among students during exams in Riyadh City, Kingdom of Saudi Arabia. A cross-sectional study was designed; using a self-administered twenty-two item online questionnaire for the students' convenience and easy response disclosure. Data were analyzed using Statistical Package for Social Science (SPSS) version 13®. A total of N = 1596 students participated in this survey, of whom 829 (51.9%) were university students and 767 (48.1%) were high school students. Overall, 80.0% of the respondents disclosed the use of OTC non-steroidal anti-inflammatory drugs for headache and pain relief. In addition, other substances used during the exams were Energy Drinks (5.0%), Flu Medication (5.0%), Vitamins (5.0%) and Antibiotics (5.0%). Female students were found to be more knowledgeable about safety issues concerning the use of OTC medicines (5.11 ± 1.27, p = media were the main factors disclosed by the respondents that may result in an increase in the use of OTC products. The use of OTC medicines was generally higher among female students (p = 0.001). The use of OTC medication during exams was more among high school and university students. Gender, age and educational institution were found significantly affecting the use of OTC medicines during exams.

    To assess test anxiety levels and related factors among students preparing for university exams. The descriptive, cross-sectional study was conducted at Istanbul University, Turkey, and comprised students preparing for exams in two private courses for the 2010-11 academic year. Data was collected via an original questionnaire and the Test Anxiety Inventory. SPSS 20 was used for statistical analyses. Of the 1250 students who qualified for the study, the final sample size was 376 (30%). Of them, 210 (55.9%) were females, and 154 (41%) were 18 years old. Students' mean Test Anxiety Inventory scores were 39.44±11.34. Female students' overall test anxiety scores and mean emotionality subscale score were significantly higher than those of their male counterparts. Students whose mothers had an educational attainment between primary school n=170 (45.2%) and a high school diploma n=184 (48.9%), as well as those with four or more siblings n=49 (15%), had significantly higher mean overall Test Anxiety Inventory scores. Among other things, test anxiety is influenced by maternal educational level, type of high school, number of exams, and number of siblings. Preparing a relaxed study environment for students, providing the family monetary or social support, and encouraging participation in social activities are recommendedto decreajb anxiety in students preparing for university exams.

    Zheng, Meixun; Bender, Daniel

    2018-03-13

    Computer-based testing (CBT) has made progress in health sciences education. In 2015, the authors led implementation of a CBT system (ExamSoft) at a dental school in the U.S. Guided by the Technology Acceptance Model (TAM), the purposes of this study were to (a) examine dental students' acceptance of ExamSoft; (b) understand factors impacting acceptance; and (c) evaluate the impact of ExamSoft on students' learning and exam performance. Survey and focus group data revealed that ExamSoft was well accepted by students as a testing tool and acknowledged by most for its potential to support learning. Regression analyses showed that perceived ease of use and perceived usefulness of ExamSoft significantly predicted student acceptance. Prior CBT experience and computer skills did not significantly predict acceptance of ExamSoft. Students reported that ExamSoft promoted learning in the first program year, primarily through timely and rich feedback on examination performance. t-Tests yielded mixed results on whether students performed better on computerized or paper examinations. The study contributes to the literature on CBT and the application of the TAM model in health sciences education. Findings also suggest ways in which health sciences institutions can implement CBT to maximize its potential as an assessment and learning tool.

    2002-10-01

    Many women who receive medical care in residency training clinics refuse to allow male residents to perform their pelvic exams. This study was conducted to identify which women were most likely to refuse and to learn their reasons for refusing. From January to March 1997, a questionnaire was given to all women entering a Tri-County Health office and a Planned Parenthood clinic, both in the Denver, Colorado, metropolitan area, who consented to participate in the study. Data from the questionnaire were analyzed using a statistical software package. A total of 1,437 women entered the clinics during the study period. Of these patients, 1,078 consented to complete the questionnaire. Seven of these 1,078 women did not complete the questionnaire. Women who did not know the training level of the resident performing the pelvic exam were more likely to refuse than were women who knew the training level of the resident (p =.001), but many women preferred a female physician regardless of the physician's training level. Fifty-eight percent said they would allow a male resident to observe a female attending physician perform the exam, compared with 36% who said they would allow a male resident to observe if the attending physician was a man. Common statements from those who would refuse were: "I am just more comfortable with a female," "Women do not want men to examine their private body parts," and "Women explain things better." A woman's knowledge of the resident's training level correlates with her willingness to have a pelvic exam performed by a male resident. Women who said they would refuse a pelvic exam performed by a male resident gave specific reasons for their decision.

    2008-04-01

    Full Text Available O líquido cefalorraquidiano (LCR é um fluido biológico que está em íntima relação com o sistema nervoso central (SNC. Por isso, o exame do LCR constitui um método de grande valia para o diagnóstico e o acompanhamento de diversas afecções neurológicas. Entretanto, existem poucos estudos sobre a estabilidade de seus analitos durante a etapa pré-analítica. OBJETIVO: Identificar dados existentes sobre a influência da temperatura e do tempo de estocagem, dos ciclos de congelamento/descongelamento e pré-tratamentos (centrifugação, desnaturação, adição de soro na estabilidade dos analitos do LCR. MÉTODO: Foi realizada uma revisão sistemática de artigos da literatura, usando palavras-chave da língua inglesa como storage, cerebrospinal fluid, CSF, stability, temperature e period, com base nos serviços de dados de PubMed, Highwire Press, Lilacs e Amazonas Library, os quais permitem a pesquisa bibliográfica de citações e artigos científicos. RESULTADO: A busca encontrou nove artigos, resultado da escassez de trabalhos sobre o assunto. Os analitos do LCR estudados incluíram células (número e morfologia, proteínas totais, glicose, lactato, aminoácidos, creatina, creatinina, biomarcadores e enzimas. As metodologias se basearam em microscopia óptica, ensaio imunossorvente ligado à enzima (ELISA, Imunoblot/SDS-PAGE e fotometria. CONCLUSÃO: A revisão da literatura confirma que a estabilidade da amostra de LCR sofre influência da temperatura, do tempo de estocagem e das condições de preparo pré-analítico. Os achados desta revisão sistemática podem contribuir para a ampliação dos conhecimentos no exame do LCR, assim como o melhor entendimento sobre a estabilidade da amostra.The cerebrospinal fluid (CSF is a biological fluid that is in close relation with the central nervous system (CNS.

    2015-01-01

    Adequate, efficient preparation for the ABR Diagnostic and Nuclear Medical Physics exams is key to successfully obtain ABR professional certification. Each part of the ABR exam presents its own challenges: Part I: Determine the scope of basic medical physics study material, efficiently review this material, and solve related written questions/problems. Part II: Understand imaging principles, modalities, and systems, including image acquisition, processing, and display. Understand the relationship between imaging techniques, image quality, patient dose and safety, and solve related written questions/problems. Part III: Gain crucial, practical, clinical medical physics experience. Effectively communicate and explain the practice, performance, and significance of all aspects of clinical medical physics. All three parts of the ABR exam require specific skill sets and preparation: mastery of basic physics and imaging principles; written problem solving often involving rapid calculation; responding clearly and succinctly to oral questions about the practice, methods, and significance of clinical medical physics. This symposium focuses on the preparation and skill sets necessary for each part of the ABR exam. Although there is some overlap, the nuclear exam covers a different body of knowledge than the diagnostic exam. A separate speaker will address those aspects that are unique to the nuclear exam. Medical physicists who have recently completed each of part of the ABR exam will share their experiences, insights, and preparation methods to help attendees best prepare for the challenges of each part of the ABR exam. In accordance with ABR exam security policy, no recalls or exam questions will be discussed. Learning Objectives: How to prepare for Part 1 of the ABR exam by determining the scope of basic medical physics study material and related problem solving/calculations How to Prepare for Part 2 of the ABR exam by understanding diagnostic and/or nuclear imaging physics

Although there is some overlap, the nuclear exam covers a different body of knowledge than the diagnostic exam. A separate speaker will address those aspects that are unique to the nuclear exam. Medical physicists who have recently completed each of part of the ABR exam will share their experiences, insights, and preparation methods to help attendees best prepare for the challenges of each part of the ABR exam. In accordance with ABR exam security policy, no recalls or exam questions will be discussed. Learning Objectives: How to prepare for Part 1 of the ABR exam by determining the scope of basic medical physics study material and related problem solving/calculations How to Prepare for Part 2 of the ABR exam by understanding diagnostic and/or nuclear imaging physics

    Adequate, efficient preparation for the ABR Diagnostic and Nuclear Medical Physics exams is key to successfully obtain ABR certification. Each part of the ABR exam presents its own challenges: Part I: Determine the scope of basic medical physics study material, efficiently review this material, and solve related written questions/problems. Part II: Understand imaging principles, modalities, and systems, including image acquisition, processing, and display. Understand the relationship between imaging techniques, image quality, patient dose and safety, and solve related written questions/problems. Part III: Gain crucial, practical, clinical medical physics experience. Effectively communicate and explain the practice, performance, and significance of all aspects of clinical medical physics. All parts of the ABR exam require specific skill sets and preparation: mastery of basic physics and imaging principles; written problem solving often involving rapid calculation; responding clearly and succinctly to oral questions about the practice, methods, and significance of clinical medical physics. This symposium focuses on the preparation necessary for each part of the ABR exam. Although there is some overlap, the nuclear exam covers a different body of knowledge than the diagnostic exam. A separate speaker will address those unique aspects of the nuclear exam, and how preparing for a second specialty differs from the first. Medical physicists who recently completed each ABR exam portion will share their experiences, insights, and preparation methods to help attendees best prepare for the challenges of each part of the ABR exam. In accordance with ABR exam security policy, no recalls or exam questions will be discussed.
