Title: Efeitos do exercício aeróbio ou da ingestão de suco de beterraba sobre o consumo alimentar, a antropometria e a composição corporal de mulheres hipertensas após a menopausa Abstract: Postmenopause is associated with hormonal changes that promote alterations in body composition and increase cardiovascular risk. In this context, this study aimed to evaluate the effects of a 10-day intervention with beetroot juice, physical exercise, or a control condition on dietary intake, anthropometric parameters, and body composition in postmenopausal women with hypertension. This randomized clinical trial included 53 participants allocated to three groups: beetroot juice (n = 17), physical exercise (n = 18), and control (n = 18). Anthropometric measurements, body composition assessed by bioelectrical impedance analysis, and dietary intake evaluated through 24-hour dietary recalls were analyzed. The exercise group showed reductions in waist circumference (p = 0.027) and abdominal circumference (p = 0.001), with no changes in body mass or body mass index. The beetroot juice group showed no significant changes in the evaluated parameters. No differences in dietary intake were observed among the groups, although energy and lipid intake increased over time. It was concluded that physical exercise promoted favorable changes in indicators of central adiposity, whereas beetroot juice supplementation produced no detectable effects on body composition or dietary intake during the study period.

Associação entre o índice de conicidade e a função renal da população brasileira: Pesquisa Nacional de Saúde, 2014-2015

Title: Associação entre o índice de conicidade e a função renal da população brasileira: Pesquisa Nacional de Saúde, 2014-2015 Abstract: INTRODUCTION: Chronic kidney disease (CKD) is a major public health problem, frequently associated with central obesity. The Conicity Index (CI) is an anthropometric indicator that assesses abdominal fat distribution. Considering the scarcity of representative studies of the Brazilian population that have evaluated the association between the CI and renal function across all categories of glomerular filtration rate, it is relevant to investigate this relationship. OBJECTIVE: To evaluate the association between the Conicity Index and renal function in the Brazilian adult population. METHODS: Cross-sectional study conducted with data from the Brazilian National Health Survey (PNS) 2014-2015. The final sample consisted of 8,535 adults with complete data on serum creatinine and anthropometric measurements. Renal function was classified according to KDIGO based on estimated glomerular filtration rate (eGFR) using the CKD-EPI 2021 equation. The CI was dichotomized, considering the upper quartile (percentile ≥ 75) as elevated. Descriptive analyses and logistic regression (crude and adjusted models) were performed, with statistical significance set at p < 0.05. RESULTS: The prevalence of eGFR < 60 mL/min/1.73 m² was 5.3%. In the crude analysis, the upper quartile of the CI was significantly associated with stages G3a (OR = 3.16), G3b (OR = 4.91), and G4 (OR = 8.53). After adjustment for sociodemographic, clinical, and behavioral factors, the association lost statistical significance. CONCLUSION: The association between the Conicity Index and renal function did not persist after adjustments, indicating a strong influence of clinical and sociodemographic factors. Longitudinal studies are recommended to better clarify this relationship.

Title: Potencial nutricional de Tenebrio molitor: efeito do método de secagem na composição bromatológica e na recuperação de proteínas. Abstract: Edible insects have been studied as an innovative alternative for human food due to their nutritional profile, global distribution, and the need to implement more sustainable food production systems. The aim of this study was to evaluate the proximate composition, the impact of drying methods on protein recovery from Tenebrio molitor flours, and the potential use of these proteins in human food. Experimental flours were obtained by freeze-drying and freeze-drying followed by oven drying, with commercial insect flour used as a control. All samples underwent proximate composition analysis and ultrasound-assisted alkaline extraction. The results showed that the drying methods did not significantly affect the protein content of the flours, which ranged from 47.2% to 50.5%. However, in the protein fraction obtained after alkaline extraction, the flour subjected exclusively to freeze-drying showed a higher protein content (66.04%) compared with the flour subjected to combined drying (65.63%), while the commercial flour presented 69.76%. No significant differences were observed among treatments for the other proximate composition parameters evaluated. It was concluded that T. molitor flours presented a high protein content, consistent with values reported in the literature, and that freeze-drying favored protein recovery after alkaline extraction, highlighting the potential of T. molitor flour as a protein ingredient for use in human food.
