Avaliação do teste imunocromatográfico ("ICT card test") no diagnóstico da filariose em estudos populacionais

This study evaluated the whole blood immunochromatographic card test (ICT card test) in a survey performed in Northeastern Brazil. 625 people were examined by the thick blood film (TBF) and ICT card test. Residents of a non-endemic area were also tested by the whole blood card test and Og4C3. The sensitivity of the ICT card test was 94.7% overall, but lower in females than males, based on the reasonable assumption that TBF is 100% specific. However, since TBF and other methods have unknown sensitivity, the true specificity of the card test is unknown. Nevertheless, it is possible to estimate upper and lower limits for the specificity, and relate it to the prevalence of the disease. In the endemic area, the possible range of the specificity was from 72.4% to 100%. 29.6% of the card tests performed in the non-endemic area exhibited faint lines that were interpreted as positives. Characteristics of the method including high sensitivity, promptness and simplicity justify its use for screening of filariasis. However, detailed information about the correct interpretation in case of extremely faint lines is essential. Further studies designed to consider problems arising from imperfect standards are necessary, as is a sounder diagnostic definition for the card test.Este estudo avaliou o teste imunocromatográfico ("ICT card test") em inquérito de filariose realizado no município de Olinda, Brasil. 625 pessoas foram examinadas pela técnica da gota espessa (GE), e "ICT card test" (ICT). Moradores do município de Campina Grande, Paraíba, área não endêmica, foram examinados pelos testes ICT e Og4C3-ELISA, para verificação da especificidade. A sensibilidade do método foi de 94,7%. O desenho do estudo - que envolveu a acurácia do ICT e do teste de referência (GE), em todos os elementos da amostra, - e a especificidade de 100% da GE permitiram o cálculo correto da sensibilidade. Todavia, como a sensibilidade da GE é desconhecida, a especificidade do ICT é ignorada. É possível, contudo, estimar o limite superior e inferior da especificidade e relacioná-la à prevalência de doença. Na área endêmica, a especificidade do teste variou entre 72,4% e 100,0%. 29,6% dos exames pelo ICT, realizados na área não endêmica, exibiram coloração tênue, tendo sido interpretados como positivos. Algumas características do método, incluindo alta sensibilidade, rapidez e simplicidade de execução justificam sua utilização em rastreamento de áreas endêmicas. Todavia, detalhes acerca da correta interpretação dos resultados com coloração extremamente tênue, parecem de importância fundamental

Swelfe: a detector of internal repeats in sequences and structures

Summary: Intragenic duplications of genetic material have important biological roles because of their protein sequence and structural consequences. We developed Swelfe to find internal repeats at three levels. Swelfe quickly identifies statistically significant internal repeats in DNA and amino acid sequences and in 3D structures using dynamic programming. The associated web server also shows the relationships between repeats at each level and facilitates visualization of the results

Evaluation of diagnostic tests for Wuchereria bancrofti infection in Brazilian schoolchildren.

INTRODUCTION: Since the launch of the Global Programme to Eliminate Lymphatic Filariasis, more than 70% of the endemic countries have implemented mass drug administration (MDA) to interrupt disease transmission. The monitoring of filarial infection in sentinel populations, particularly schoolchildren, is recommended to assess the impact of MDA. A key issue is choosing the appropriate tools for these initial assessments (to define the best intervention) and for monitoring transmission. METHODS: This study compared the pre-MDA performance of five diagnostic methods, namely, thick film test, Knott's technique, filtration, Og4C3-ELISA, and the AD12-ICT card test, in schoolchildren from Brazil. Venous and capillary blood samples were collected between 11 pm and 1 am. The microfilarial loads were analyzed with a negative binomial regression, and the prevalence and associated 95% confidence intervals were estimated for all methods. The accuracies of the AD12-ICT card and Og4C3-ELISA tests were assessed against the combination of parasitological test results. RESULTS: A total of 805 schoolchildren were examined. The overall and stratified prevalence by age group and gender detected by Og4C3-ELISA and AD12-ICT were markedly higher than the prevalence estimated by the parasitological methods. The sensitivity of the AD12-ICT card and Og4C3-ELISA tests was approximately 100%, and the positive likelihood ratios were above 6. The specificity of the Og4C3-ELISA was higher than that of the AD12-ICT at different prevalence levels. CONCLUSIONS: The ICT card test should be the recommended tool for monitoring school-age populations living in areas with ongoing or completed MDA

Relativistic effects and quasipotential equations

We compare the scattering amplitude resulting from the several quasipotential equations for scalar particles. We consider the Blankenbecler-Sugar, Spectator, Thompson, Erkelenz-Holinde and Equal-Time equations, which were solved numerically without decomposition into partial waves. We analyze both negative-energy state components of the propagators and retardation effects. We found that the scattering solutions of the Spectator and the Equal-Time equations are very close to the nonrelativistic solution even at high energies. The overall relativistic effect increases with the energy. The width of the band for the relative uncertainty in the real part of the scattering $T$ matrix, due to different dynamical equations, is largest for backward-scattering angles where it can be as large as 40%.Comment: Accepted for publication in Phys.

Impacto de la violencia laboral en la salud ocupacional en médicos internos y residentes de hospitales de la ciudad de México: Impacto da violência no local de trabalho na saúde ocupacional em médicos internos e residentes hospitalares na Cidade do México

La violencia laboral hoy en día está siendo objeto de un mayor número de investigaciones por las repercusiones que tiene para los trabajadores y para las organizaciones. Además, en la actualidad existen más voces y evidencias de actos de violencia que ocurren en las organizaciones, incluidas las del sector salud. El objetivo de esta investigación fue determinar el impacto de la violencia laboral en variables de salud ocupacional (estrés, trastornos psicosomáticos y salud percibida) de una muestra de médicos internos y residentes de diez hospitales de la Ciudad de México. Para lograr este objetivo se realizó una investigación descriptiva y explicativa. Se obtuvo una muestra de 387 médicos, de los cuales 161 fueron internos y 226 residentes. La violencia laboral fue la variable independiente y como variables dependientes se consideraron tres variables de salud ocupacional: estrés, trastornos psicosomáticos y salud percibida. Los resultados obtenidos indican que existe violencia laboral en diferentes niveles en un alto porcentaje en los médicos y residentes considerados en la muestra: del 36.2% al 80.1% en los factores de violencia laboral. Además, Se identificaron efectos significativos en la salud percibida (ansiedad, disfunción social y depresión) de factores tales como la violencia verbal, la comunicación deteriorada, castigos, el hostigamiento sexual, la desacreditación profesional, así como el maltrato y humillación. Estos resultados indican la necesidad de realizar cambios organizacionales y cambios en la cultura organizacional de las organizaciones del sector salud que contribuyan a generar ambientes de trabajo y organizaciones saludables
