Brazilian guide to nutrition in bariatric and metabolic surgery.

Purpose: Brazilian nutrition recommendations for bariatric and metabolic surgery aim to provide knowledge, based on scientific evidence, on nutritional practices related to different surgical techniques in the surgical treatment of obesity and metabolic diseases.

Materials And Methods: A systematic literature search was carried out with the appropriate MeSH terms using Medline/Pubmed/LiLACS and the Cochrane database, with the established criteria being based on the inclusion of articles according to the degree of recommendation and strength of evidence of the Classification of Recommendations, Evaluation, Development, and Evaluation System (GRADE).

Results: The recommendations that make up this guide were gathered to assist in the individualized clinical practice of nutritionists in the nutritional management of patients with obesity, including nutritional management in the intragastric balloon; pre and postoperative nutritional treatment and supplementation in bariatric and metabolic surgeries (adolescents, adults, elderly, pregnant women, and vegetarians); hypoglycemia and reactive hyperinsulinemia; and recurrence of obesity, gut microbiota, and inflammatory bowel diseases.

Postprandial adiponectin levels are associated with improvements in postprandial triglycerides after Roux-en-Y gastric bypass in type 2 diabetic patients.

Background: Postprandial hypertrygliceridemia is a known factor for cardiovascular disease and is often observed in patients with type 2 diabetes mellitus (T2DM) and visceral adiposity. Adiponectin is a hormone with antiatherogenic and anti-inflammatory effects, which decreases in obesity and T2DM subjects. The weight loss induced by diet or bariatric surgery could be restoring adiponectin levels.

Early improvement in glycemic control after bariatric surgery and its relationships with insulin, GLP-1, and glucagon secretion in type 2 diabetic patients.

Background: The surgical treatment of obesity ameliorates metabolic abnormalities in patients with type 2 diabetes. The objective of this study was to evaluate the early effects of Roux-en-Y gastric bypass (RYGB) on metabolic and hormonal parameters in patients with type 2 diabetes (T2DM).

Methods: Ten patients with T2DM (BMI, 39.

[Acromegaly and thyroid disease: prevalence of thyroid cancer].

The relationship between cancer and acromegaly has been subject of study for many years. From a case of differentiated thyroid carcinoma in one of our acromegalic patients, we reviewed a series of 100 acromegalics and found two others cases of thyroid cancer, which are described in this work. From that point, we have got data from the literature about this last association and its possible pathogenesis.
