“…However, this was not possible, because one of its assumptions was not met, which is the normality of the sample data. To verify the non-normality, this research used the Kolmogorov-Smirnov test (Contador & Senne, 2016), observing the maximum absolute difference between the normal and the empirical role of data. The Cronbach's alpha coefficient was calculated to assess the internal consistency of the WHO-QOL-Bref questionnaire.…”

Validation and applicability of an alternative method for dialysis water and dialysate quality analysis

et al. 2020

Introduction: In hemodialysis, patients are exposed to a large volume of water, which may lead to fatal risks if not meeting quality standards. This study aimed to validate an alternative method for monitoring microbiological quality of treated water and assess its applicability in dialysis and dialysate analysis, to allow corrective actions in real-time. Methods: Validation and applicability were analyzed by conventional and alternative methods. For validation, E. coli standard endotoxin was diluted with apyrogenic water in five concentrations. For the applicability analysis, treated water for dialysis was collected from different points in the treatment system (reverse osmosis, drainage canalization at the storage tank bottom, reuse, and loop), and dialysate was collected from four machines located in different rooms in the hemodialysis sector. Results: The validation results were in accordance with the Brazilian Pharmacopoeia acceptance criteria, except for the last two concentrations analyzed. In addition, the ruggedness criterion performed under the US Pharmacopoeia was in agreement with the results. Discussion: A limiting factor in the applicability analysis was the absence of the endotoxin maximum permitted level in dialysate by the Brazilian legislation. When comparing the analysis time, the alternative method was more time-consuming than the conventional one. This suggests that the alternative method is effective in the case of few analyses, that is, real-time analyses, favoring corrective actions promptly. On the other hand, it does not support the implementation of the alternative method in a laboratory routine due to the high demand for analyses.

RESUMO Objetiva-se determinar a prevalência de mulheres com risco de desenvolvimento de câncer de mama pelo histórico familiar em Uberaba (MG), e essa prevalência nas diferentes condições socioeconômicas e epidemiológicas. Pesquisa quantitativa, analítica, observacional e transversal de base populacional. Amostra com 1.520 mulheres a partir de 20 anos. Dados coletados por entrevistas domiciliares sobre informações socioeconômicas e epidemiológicas. A avaliação do risco hereditário de câncer de mama foi realizada pelo Family History Screen-7 (FHS-7). Como resultado, 28,6% da amostra apresentaram risco hereditário para câncer de mama. Houve associação significativa do risco de câncer quanto a: faixa etária, sendo nas mulheres com idade de 70 anos ou mais a maior proporção com risco (33,5%); etnia, sendo a maior proporção entre mulheres de etnia branca (31,2%); renda familiar, com maior ocorrência para renda per capita > 2,5 salários-mínimos (31,6%); prática de exames preventivos (30,6%); e alterações benignas na mama (46,7%). Conclui-se que, a partir do histórico familiar pelo FHS-7, o risco de as mulheres desenvolverem câncer mostrou-se significativamente associado com maior faixa etária, etnia branca e maior renda per capita, com a prática de exames preventivos em dia e alterações benignas na mama. Tais resultados possibilitam melhores direcionamentos de políticas públicas.
