Conclusions: Most hospitalized oncological elderly were found to be eutrophic by the anthropometric indicators body mass index and calf circumference, while a higher proportion of these patients were classified as malnourished or at nutritional risk by the Mini Nutritional Assessment Reduced Forms, as well as by the percentage of weight loss. Patients with lung and pancreas cancer had the most severe weight loss. These results confirm the importance of using different parameters to assess the nutritional status of elderly with cancer.

Overweightness is related to a high incidence of dyslipidemia, being considered a risk factor for cardiovascular diseases.Objective: Analysis of the effect of weight loss in reducing type 2 diabetes mellitus and cardiovascular risk 2 years after Roux-en-Y gastric bypass.Methods: A retrospective study with patients who underwent Roux-en-Y gastric bypass involving accessing the database of an Obesity Surgery Clinic from March 2018 to March 2019. Male and female patients, aged 18 and over, who underwent bariatric surgery from March 2014 to March 2016 were analyzed. The following data were obtained from the medical records of patients: body weight, height, age, sex, glucose and glycated hemoglobin (HbA1C) after 24 months of surgery.Results: In total, 351 patients were studied, 80.9% of whom were female. There was a reduction in weight and in the concentrations of all biochemical parameters, except HDLc, along with a decrease in the frequency of dyslipidemia and cardiovascular risk 24 months after surgery. When comparing variations between 6 and 12 months, only group 1 reduced Hb1Ac and decreased CVR. There was a significant reduction in the level of glucose in group 1 (p = 0.036) at T4 (18 months) and T5 (24 months).Conclusion: The positive impact determined by bariatric surgery on weight loss was shown to be effective in improving the dyslipidemic profile, reducing morbidities associated with obesity and, consequently, reducing CVR after 24 months.

Background: Obesity has increased in prevalence and thus has become a public health crisis. The objective of this study was to evaluate the impact of weight loss on the resolution of type 2 diabetes mellitus and cardiovascular risk. Methods: This is a retrospective cohort and descriptive study, involved consulting a database, from March 2018 to March 2019. The subjects were  female and male patients, ≥18 years, who had been submitted to bariatric surgery  from March 2014 to March 2016. The following data were obtained from their  charts: weight, height, age, sex, presence of associated morbidities (type 2 diabetes mellitus, cardiovascular risk), glycated hemoglobina and glucose. The data a presented as the mean and standard deviation, median and interquartile range, or count and percentage. The results were considered statistically significant if p-value ≤0.05. Results: The patients had maintained a substantial percentage of excesso wheight loss (%EWL) during the postoperative period, and the Hb1Ac, glucose, CVR, and metabolic alterations were also reduced. Six months after surgery, group 1 (<70% EWL) and group 2 (≥ 70%) showed reduced Hb1Ac and, glucose and only group 2 showed reduced CVR. From 12 to 18 months after surgery, group 1 showed reduced Hb1Ac. From 18 to 24 months after surgery, group 2 showed reduced CVR and group 1 showed reduced glucose. Conclusion: Bariatric surgery had a positive effect on %EWL and modified the metabolic profile and CVR of patients up to 24 months after gastric bypass, reducing associated comorbidities.
