Objective: Obesity can cause systemic arterial hypertension (SAH) and type 2 diabetes mellitus (DM2) factor that is also influenced by genetic variability. The present study aims to investigate the association between gene polymorphisms related with obesity on the prevalence of SAH and DM2 in the preoperative period and 1 year after Roux-en-Y gastric bypass surgery.
Subjects And Methods: In total, 351 obese women in a Brazilian cohort completed the study.
Aim: The aim this study was to evaluate the influence of gastric bypass surgery (GBS) on periodontal disease and quantify the periodontopathogenic bacteria in patients undergoing this surgery.
Material And Methods: This prospective study was composed of 50 patients who underwent bariatric surgery and the data collection was performed in three periods pre-operative, 6 (6M) and 12 months (12 M) postoperative. The oral clinical examination to assess periodontal disease; gingival fluid sample collection for quantification of the periodontopathogenic bacteria Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, and Prevotella intermedia using q-PCR; body mass index (BMI) and for collection of the individual's health-related data from medical files.
Unlabelled: In addition to its important role as marker of iron stores, serum ferritin is a marker of systemic inflammation, and obesity has been associated with chronic inflammation.
Objective: To verify, six months after surgery, the effect of bariatric surgery on the serum ferritin of women who were hypertensive, diabetic, or comorbidity free before surgery.
Sample And Methods: This retrospective study included 200 women aged 20 to 45 years, with a body mass index (BMI) equal to or greater than 35 kg/m2, submitted to Roux-en-Y gastric bypass (RYGB).
Objectives: We evaluate oral health conditions before and after bariatric surgery.
Methods: The sample was composed of 59 patients who had undergone Roux-en-Y gastric bypass (RYGB). Salivary flow, periodontal pocket depth and dental wear were evaluated before and after 6 months of surgery.
Purpose: To evaluate the frequency of obstructive sleep apnea (OSA) in obese patients scheduled for bariatric surgery and their identification for risk of OSA by Berlin Questionnaire (BQ) and excessive daytime sleepiness by Epworth Sleepiness Scale (ESS).
Methods: Fifty nine patients were evaluated by BQ and ESS. Out of these individuals, 35 performed a full-night sleep study using a type 3 portable monitoring (PM).
Background: Use of ring in Roux-en-Y gastric bypass is still a matter of controversy among bariatric surgeons. There is no consensus on its impact in relation to weight loss and weight maintenance in the long term.
Aim: To evaluate the influence of the ring on the evolution of body weight over four years after bariatric surgery.
Restricted food intake after bariatric surgery can be an important factor both in the long-term control of body weight and in the onset of nutritional deficiencies. The objective of this study was to assess the adequacy of food intake in women two or more years after bariatric surgery according to the excess weight lost. A group of 141 women who underwent banded Roux-en-Y gastric bypass (RYGB) was divided according to the percentage of excess weight they lost (%EWL)<50; 50┤75; = 75.

Methods: Incisional hernia was experimentally developed through a 4-cm median incision in 60 rabbits. After 30 days, half of the animals were operated for primary wall closure and placement of a polypropylene mesh reinforcement, while the other half had a polypropylene mesh sutured to the borders of the hernial ring as a bridge.
Objective: The objective of this study was to assess the evolution and classification of body weight in relation to the results of bariatric surgery in women who underwent the procedure more than two years ago.
Subjects And Method: A total of 141 women underwent banded Roux-en-Y gastric bypass (RYGB). The participants were divided according to the time elapsed since surgery and the percentage of excess weight lost (%EWL): < 50; 50 upper and lower left quadrants 75; and > 75.
Aim: To verify the methylation status of CDH1, DAPK, COX2, hMLH1 and CDKN2A genes and to evaluate their association with Helicobacter pylori (H. pylori)-cagA(+) and Epstein Barr virus (EBV) infections in gastric adenocarcinomas.
Methods: Methylation-specific PCR (MSP) assay was performed in 89 primary gastric carcinomas (intestinal and diffuse types).
Purpose: To study the effect of protein malnutrition on the intestinal wall of rats by evaluating alterations in the rupture force and dosing tissue collagen in the ileum and distal colon.
Methods: One hundred and twenty rats, that had an average weight of 100g, were used. They received water and a standard diet with 20% protein during 7 days for adaptation to the diet itself and to environmental conditions.
