Material e Métodos Estudo prospectivo com amostras de sangue periférico do Laboratório de Patologia Clínica Dr. Paulo C. Azevedo, independente de idade e sexo, para validação da contagem de eritroblastos no analisador hematológico Mindray BC6000 em comparação ao método manual (padrão ouro), no período de junho de 2019 a dezembro de 2020. Resultados Foram analisadas 17 amostras de sangue periférico de recém-nascidos (17/09 - 52,3%) e de pacientes maiores de 2 anos (17/08 - 47,7%) que apresentavam mais de 18% de eritroblastos após análise morfológica da amostra. A análise estatística das contagens de eritroblastos pelas duas metodologias mostrou que o contador hematológico Mindray BC6000 tem boa reprodutibilidade, precisão e linearidade. Não houve correlação entre os estágios de maturação dos eritroblastos e os gráficos do equipamento. Conclusão A validação proposta mostrou que o contador hematológico Mindray BC6000 apresenta bom desempenho analítico para contagem de eritroblastos em sangue periférico. Porém, não há correlação entre os estágios de maturação dos eritroblastos com os gráficos gerados pelo equipamento.

Psychometric properties of the Chinese version of the trust between People and Automation Scale (TPAS) in Chinese adults

Trust in automation plays a leading role in human-automation interaction. As there lack of scales measuring trust in automation in China, the purpose of this study was to adapt the trust between People and Automation Scale (TPAS) into Chinese and to demonstrate its psychometric properties among Chinese adults. A total of 310 Chinese adults were randomly selected as sample 1, and 508 Chinese adults as sample 2. Results of the item analysis revealed that each item had a good quality, and the exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) suggested that the two-factor model with 12 items was the best fitting model. In addition, the TPAS was positively correlated with Interpersonal Trust Scale (ITS), proving good evidence based on relations to other variables to support the TPAS. In sum, the study suggested that the Chinese version of the TPAS could be used as an effective tool to assess trust in automation in the Chinese context.

Acústicas bioquímicas semi-automatizadas por processamento de imagem Dipstick com base em arduino / Biochemical semi-automated acoustics by Dipstick image processing based on arduino

Apesar da ampla disponibilidade de dispositivos para leitura de tiras reativas para análise de urina, falhas potenciais persistem na rotina baseada na interpretação humana. O objetivo deste estudo foi desenvolver e avaliar o desempenho de um dispositivo baseado em Arduino para a leitura semi-automática de parâmetros de fitas reativas. O parâmetro glicose de um modelo de tira reativa comercial foi analisado pelo sistema, que prevê a concentração do analito submetendo a cor observada na tira a um modelo de regressão, ajustado a um banco de dados de padrões de cores. O sistema foi avaliado através da leitura de 80 tiras com 16 amostras de concentrações aleatórias de glicose. O menor coeficiente de variação após cinco leituras replicadas foi de 4,5% e o mais alto foi de 16,6% (MSE = 68,7 mg / dL; r = 0,979). O dispositivo apresentou resultados satisfatórios mais baixos custos. Para torná-lo útil na rotina laboratorial, seriam necessárias novas experiências com outros parâmetros e outras classes de tiras reativas para análise de urina.

Although many devices are available to read urinalysis reactive strips, potential failure, based on human interpretation, persists in routine tasks. Current study develops and evaluates the performance of an Arduino-based device for the semi-automated reading of reactive strip parameters. The glucose parameter of a commercial reactive strip model was analyzed by the system, which predicts analyte concentration by submitting the color observed in the strip to a regression model, adjusted to a database of color patterns. The system was assessed by reading of 80 strips with 16 samples of random glucose concentrations. The lowest coefficient of variation after five replicated readings was 4.5% and the highest was 16.6% (MSE=68.7 mg/dL; r=0.979). The device featured satisfactory results plus low costs. To make it useful in the laboratory routine, further experiments with other parameters and other classes of urinalysis reactive strips would be necessary.
