RESUMO Objetivo Adaptar um software de ajuste de dose de antibióticos inicialmente elaborado em língua inglesa para o português e a conjuntura brasileira. Métodos Trata-se de estudo observacional, descritivo, em que foi utilizado o método Delphi para estabelecer consenso entre especialistas de diferentes áreas da saúde, com perguntas que abordaram os aspectos visuais e operacionais do software. Em uma segunda etapa, foi realizado um estudo piloto, experimental, com alocação aleatória dos pacientes, para avaliação e adaptação do software em ambiente real de uma unidade de tratamento intensivo, onde foram comparadas diferenças entre pacientes que utilizaram dose padronizada usual de piperacilina/tazobactam, e os que utilizaram a dose individualizada ajustada por meio do software Individually Designed Optimum Dosing Strategies. Resultados Participaram da primeira rodada 12 profissionais cujas sugestões foram encaminhadas ao desenvolvedor do software para adequação e ajustes, e posteriormente submetidas à segunda rodada. Oito especialistas participaram da segunda rodada. Foram obtidos índices de 80% e 90% de concordância entre os juízes, caracterizando uniformidade nas sugestões. Dessa forma, houve modificação no layout do software para adequação linguística e cultural, minimizando erros de entendimento e contradições. Na segunda etapa, foram incluídos 21 pacientes, e não houve diferenças entre doses de piperacilina nos grupos dose padronizada e dose ajustada. Conclusão A versão adaptada do software é segura e confiável para seu uso no Brasil.

ABSTRACT Objective To adapt an antibiotic dose adjustment software initially developed in English, to Portuguese and to the Brazilian context. Methods This was an observational, descriptive study in which the Delphi method was used to establish consensus among specialists from different health areas, with questions addressing the visual and operational aspects of the software. In a second stage, a pilot experimental study was performed with the random comparison of patients for evaluation and adaptation of the software in the real environment of an intensive care unit, where it was compared between patients who used the standardized dose of piperacillin/tazobactam, and those who used an individualized dose adjusted through the software Individually Designed and Optimized Dosing Strategies. Results Twelve professionals participated in the first round, whose suggestions were forwarded to the software developer for adjustments, and subsequently submitted to the second round. Eight specialists participated in the second round. Indexes of 80% and 90% of concordance were obtained between the judges, characterizing uniformity in the suggestions. Thus, there was modification in the layout of the software for linguistic and cultural adequacy, minimizing errors of understanding and contradictions. In the second stage, 21 patients were included, and there were no differences between doses of piperacillin in the standard dose and adjusted dose Groups. Conclusion The adapted version of the software is safe and reliable for its use in Brazil.

This study estimated the genetic diversity and structure of 12 genetic groups (GG) of locally adapted and specialized pigs in the state of Pernambuco using 22 microsatellite markers. Nine locally adapted breeds (Baé, Caruncho, Canastra, Canastrão, Mamelado, Moura, Nilo, Piau and UDB (Undefined Breed)) and 3 specialized breeds (Duroc, Landrace and Large White), totaling 190 animals, were analyzed. The Analysis of Molecular Variance (AMOVA) showed that 3.2% of the total variation was due to differences between genetic groups, and 3.6% to differences between local and commercial pigs. One hundred and ninety eight alleles were identified and apart from the Large White breed, all GG presented Hardy-Weinberg Equilibrium deviations for some loci. The total and effective allele means were lower for Duroc (3.65 and 3.01) and higher for UDB (8.89 and 4.53) and Canastra (8.61 and 4.58). Using Nei's standard genetic distance and the UPGMA method, it was possible to observe that the Landrace breed was grouped with the local genetic groups Canastra, Moura, Canastrão, Baé and Caruncho. Due to the complex admixture pattern, the genetic variability of the 12 genetic groups can be analyzed by distributing the individuals into two populations as demonstrated by a Bayesian analysis, corroborating the results from AMOVA, which revealed a low level of genetic differentiation between the inferred populations.

OBJETIVOS: Avaliar diferentes métodos diagnósticos para a avaliação de pacientes portadores de lúpus eritematoso sistêmico, usuários crônicos do difosfato de cloroquina (DFC) e, portanto, com alto risco para retinopatia tóxica. MÉTODOS: Foram analisados 72 olhos de 36 pacientes consecutivos, seguidos no Serviço de Reumatologia do Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo, de julho de 2007 a abril de 2008. Dados demográficos e clínicos foram avaliados com o intuito de estudar os fatores de alto risco e comparar os seguintes métodos oftalmológicos: acuidade visual, biomicroscopia da córnea, biomicroscopia do fundo, retinografia, angiofluoresceinografia da retina, campo visual macular com mira branca. RESULTADOS: Dos 36 pacientes, 34 (94,4%) eram mulheres. A média de idade foi 39,9 ± 9,8 anos, com tempo de doença igual a 13,9 ± 6,6 anos. Além do uso crônico da cloroquina, os pacientes apresentaram altas doses diárias (>3 mg/kg) e cumulativas. Não foi observada relação entre estes fatores de alto risco e maior prevalência de retinopatia. Foi encontrada prevalência de retinopatia igual a 38,9%, confirmada por alterações bilaterais, centrais ou paracentrais e reprodutíveis no exame de campo visual. Outros exames indicados para seguimento, como acuidade visual, biomicroscopia de fundo e angiofluoresceinografia não foram capazes de diagnosticar a maioria das alterações confirmadas pelo campo visual. CONCLUSÃO: Foi observada alta prevalência de retinopatia por cloroquina entre os pacientes com alto risco, usuários crônicos do DFC, segundo os achados do campo visual. A avaliação desses pacientes deve considerar a realização do exame de campo visual em intervalos menores que os propostos, mesmo quando não há suspeita clínica.

PURPOSE: To evaluate different diagnostic methods for high risk chloroquine retinopathy due to prolonged use of chloroquine (more than 5 years) by systemic lupus erythematosus patients. Methods: Seventy-two eyes of 36 consecutive patients, followed in the Division of Rheumatology, School of Medicine, University of São Paulo, were analyzed from July 2007 to April 2008. Demographic and clinical data were evaluated in order to study risk factors and to compare the following different ophthalmological methods: visual acuity, biomicroscopy, fundus examination, retinography, fluorescein angiogram, visual field test and, color vision tests. RESULTS: From 36 patients, 34 (94.4%) were female. The mean age was 39.9 ± 9.8 years and the disease duration was 13.9 ± 6.6 years. Besides chronic use of chloroquine, patients also showed high daily and cumulative doses. These high risk factors were not related to a higher retinopathy prevalence. Visual field showed 38.9% of retinopathy prevalence. Other ophthalmological methods failed in detecting most cases. CONCLUSION: High prevalence of retinopathy in high risk patients was observed by visual field test, but other ophthalmological methods failed in detecting alterations. Ophthalmological assessment of these patients should include visual field, even in the absence of clinical alterations.
