Effects of Green Banana Biomass (Musa spp.) on Laboratory Parameters of Animal Models of Wistar Mice under Hyperlipidic Diet.

AIM: Analyze the effects of green banana biomass (Musa spp.) on the biochemical parameters in Wistar male rats under standard and hyperlipidic diet. METHODS: Ethical approval for this study was obtained from Ethics Committee on the Use of Animals CEUA - PUC-GO and consisted in the division of 32 rats in 4 differentiated groups according to their diet (standard - CT; standard with green banana biomass - CTBM; hyperlipidic - HL and hyperlipidic with green banana biomass - HLBM). Through 8 weeks animals were weighted and their glycemia were measured. After this period, they were euthanized and biological material was collected to evaluate the biochemical parameters, which analysis used the ANOVA test. RESULTS: The weekly evaluation confirmed that the efficacy of the hyperlipidic model since the final weight was bigger in the HL group in comparison with the CT group, from the sixth to the eighth week. It was also possible to observe that the CTBM group had a smaller weight compared to the CT group. Besides, the measurement of glycemia, high-density lipoprotein, triglycerides, alanine aminotransferase, aspartate aminotransferase, serum total bilirubin, direct bilirubin, alkaline phosphatase, urea, serum creatine, uric acid, calcium, phosphor, magnesium and the hematological parameters from the 8 animal of each group were compared by the ANOVA test without any significative difference (p < 0.05) in the comparisons. CONCLUSIONS: This study it did not demonstrate significative changes of the green banana biomass on the observed laboratory parameters during the 8 weeks in comparison to the standard group, indicating an absence of interference of the probiotics in the laboratory parameters on the hyperlipidic model during the analyzed period. Therefore, it is necessary an evaluation of its efficacy in obesity treatment in longer studies with molecular parameters.

[Beliefs of diabetic patients about nutritional therapy and its influence on their compliance with treatment]. / Crenças de pacientes diabéticos acerca da terapia nutricional e sua influência na adesão ao tratamento.

The system of health beliefs influences the process of compliance with diabetes treatment. Compliance with nutritional therapy is one of the greatest challenges found. The purpose of this qualitative approach study was to analyze the beliefs of type 2 diabetic patients regarding nutritional therapy and its influence on the compliance with it. The participants of the study were nine patients being treated in a reference unit for diabetic patients' treatment. The procedures involved were blood exam to check the glycated hemoglobin, a questionnaire, semi-structured recorded interview and patient report checking. The analysis of the speeches was made using the thematic categories of Bardin (2000), and the models of Rokeach (1981) and Rosenstock (1974). All participants showed glycated hemoglobin levels higher than 7%, what shows that is difficult for them to control their glicemic levels and possible non compliance. After the analysis of the speeches, two thematic categories were identified: 'Recommendations received about feeding' and 'Nutritional therapy compliance'. Both categories showed authority beliefs and consensus zero, and barriers to nutritional therapy, which the participants see as a restrictive imposition. Those beliefs have negative influence on the compliance, and so, they have to be considered when providing health assistance to the population.

Crenças de pacientes diabéticos acerca da terapia nutricional e sua influência na adesão ao tratamento / Beliefs of diabetic patients about nutritional therapy and its influence on their compliance with treatment

O sistema de crenças em saúde influencia o processo de adesão ao tratamento de diabetes. A adesão à terapia nutricional é um dos maiores desafios. O objetivo desse estudo de abordagem qualitativa foi analisar as crenças de pacientes diabéticos tipo 2 a respeito da terapia nutricional e sua influência na adesão. Participaram do estudo nove pacientes em tratamento em um centro de referência para atendimento à diabéticos. Os procedimentos envolvidos foram coleta de sangue para dosagem de hemoglobina glicada, aplicação de questionário, entrevista semi-estruturada gravada e consulta ao prontuário. A análise das falas foi feita a partir do modelo de categorias temáticas de Bardin, e segundo os modelos de crenças de Rosenstock e Rokeach. Todos os participantes apresentaram níveis de hemoglobina glicada acima de 7 por cento, denotando dificuldade para o controle glicêmico e possível falta de adesão. Pela análise das falas, foram identificadas duas categorias temáticas: "Recomendações recebidas sobre alimentação" e "Adesão à terapia nutricional". Elas revelam crenças de autoridade e de consenso zero, e de barreiras à terapia nutricional, percebida como imposição restritiva. São crenças que influenciam negativamente a adesão; assim, precisam ser consideradas no atendimento à população.
