    OBJETIVO: O objetivo da pesquisa foi determinar a perda de massa corporal magra em pacientes após cirurgia bariátrica. MÉTODOS: O estudo retrospectivo foi conduzido com 17 prontuários de mulheres obesas submetidas à Derivação Gástrica em Y de Roux com anel de contenção gástrica, incluindo dados obtidos no período pré-operatório imediato e no 1º, 3º, 6º e 12º meses após a cirurgia. Os dados obtidos no prontuário incluíram a idade, medidas de peso, de altura e massa corporal magra e gorda, calculados pela impedância bioelétrica. RESULTADOS: A média de idade das pacientes foi de 43,1, DP=7,7 anos e durante o seguimento houve diminuição significativa do índice de massa corporal [51,2 (40,2-74,1) para 33,7 (24,8-53,4)kg/m²] e da massa corporal gorda [67,5 (51,2-67,4) para 32,1 (16,4-61,9)kg] em 12 meses de seguimento. No primeiro mês após a cirurgia, houve diminuição da massa corporal magra (M=65,3, DP=7,6 para M=59,7, DP=8,1kg), que representou 8,5% em relação aos valores iniciais, sendo que a partir daí, os dados mantiveram-se constantes. CONCLUSÃO: A perda de massa corporal magra pode refletir uma alteração no metabolismo proteico durante o pós-operatório imediato da cirurgia bariátrica, que pode implicar em evolução clínica e nutricional desfavoráveis.OBJECTIVE: The aim of this study was to determine changes in lean body mass after bariatric surgery. METHODS: This retrospective study reviewed 17 medical records of obese women who underwent banded Roux-en-Y gastric bypass. The medical records contained data collected immediately before and 1, 3, 6 and 12 months after surgery. The data included age, weight, height and lean and fat body mass determined by bioelectrical impedance analysis. RESULTS: The mean age of the patients was 43.1 years (SD=7.7). Body mass index decreased significantly within 12 months of the surgery, going from 51.2 (40.2-74.1) to 33.7 (24.8-53.4)kg/m², as did fat body mass, going from 67.5 (51.2-67.4) to 32.1 (16.4-61.9)kg. In the first month after surgery, lean body mass decreased from M=65.3 (SD=7.6) to M=59.7 (SD=8.1kg), representing a decrease of 8.5%. Lean body mass remained constant after this period. CONCLUSION: Loss of lean body mass may indicate a change in protein metabolism immediately after bariatric surgery, which may result in an unfavorable clinical and nutritional course

    Background: Polytherapy treatment is a common practice observed among menopausal patients. This study aimed to quantify food intake and medications in climacteric patients living in community. Methods: Eligible patients from Climacteric Outpatient Clinic (HCFMRP/USP) were recruited. The collected data were: food intake records, age, body weight, height, levels of physical activity and medications in use. Results: Eighty women were studied. Their age was 548 years and body mass index 307kg/m2. They had inadequate dietary Fe, K, Mg, Ca, thiamin, pyridoxine, vitamin E, folate and fiber consumption; 62% used 3 or more medications/day among hypotensive, micronutrients and anti-depressants. Conclusion: Climacteric women need special attention regarding nutrient intake and medication prescription

    Background: Pre-diabetes precedes Diabetes Mellitus (DM) disease and is a critical period for hyperglycemia treatment, especially for menopausal women, considering all metabolic alterations due to hormonal changes. Recently, the literature has demonstrated the role of physical exercise in epigenetic reprogramming to modulate the gene expression patterns of metabolic conditions, such as hyperglycemia, and prevent DM development. In the present study, we hypothesized that physical exercise training could modify the epigenetic patterns of women with poor glycemic control. Methods: 48 post-menopause women aged 60.3 ± 4.5 years were divided according to their fasting blood glucose levels into two groups: Prediabetes Group, PG (n=24), and Normal Glucose Group, NGG (n=24). All participants performed 14 weeks of physical exercise three times a week. The Infinium Methylation EPIC BeadChip measured the participants’ Different Methylated Regions (DMRs). Results: Before the intervention, the PG group had 12 DMRs compared to NGG. After the intervention, five DMRs remained different. Interestingly, when comparing the PG group before and after training, 118 DMRs were found. The enrichment analysis revealed that the genes were related to different biological functions such as energy metabolism, cell differentiation, and tumor suppression. Conclusion: Physical exercise is a relevant alternative in treating hyperglycemia and preventing DM in post-menopause women with poor glycemic control

    This study investigated the ability of the Brazilian Caffeine Expectancy Questionnaire (CaffEQ-BR), full and brief versions, to differentiate genetic profiles regarding the polymorphisms of the CYP1A2 (rs 762551) and ADORA2A (rs 5751876) genes in a cohort of Brazilian athletes. Onehundred and fifty participants were genotyped for CYP1A2 and ADORA2A. After the recruitment and selection phase, 71 (90% male and 10% female, regular caffeine consumers) completed the CaffEQ-BR questionnaires and a self-report online questionnaire concerning sociodemographic data, general health status, and frequency of caffeine consumption. The order of completion of the CaffEQBR questionnaires was counterbalanced. The concordance between the full and brief versions of the CaffEQ-BR was analyzed using the intraclass correlation coefficient (ICC). To determine the discriminatory capacity of the questionnaires for genotype, the receiver operating characteristic (ROC) curve was applied for sensitivity and specificity (significance level of 5%). Mean caffeine intake was 244 161 mg day1. The frequency of AA genotypes for CYP1A2 was 47.9% (n = 34) and 52.1% (n = 37) for C-allele carriers (AC and CC). The frequencies of TT genotypes for ADORA2A were 22.7% (n = 15) and 77.3% (n = 51) for C-allele carriers (TC and CC). All CaffEQ-BR factors, for the full and brief versions, were ICCs > 0.75, except for factor 6 (anxiety/negative effects; ICC = 0.60), and presented ROC curve values from 0.464 to 0.624 and 0.443 to 0.575 for CYP1A2 and ADORA2A. Overall, the CaffEQ-BR (full and brief versions) did not show discriminatory capacity for CYP1A2 and ADORA2A gene polymorphisms. In conclusion, the CaffEQ-BR was not able to differentiate genotypes for the CYP1A2 or ADORA2A genes in this group of Brazilian athletes
