Bilevel positive airway pressure in two moments after bariatric surgery.

Objective: To investigate the use of Bilevel Positive Airway Pressure (BiPAP) in morbidly obese individuals in two moments following bariatric surgery (Roux-en-Y gastric bypass): post-anesthetic recovery (PAR) and first postoperative day (1PO).

Design: Randomized and blinded clinical trial.

Methods: We studied 40 morbidly obese individuals aged between 25 and 55 years who underwent pulmonary function test and chest X-ray preoperatively, and on the day of discharge (2nd day after surgery).

Effects of Inspiratory Exercise With Linear and Nonlinear Load on Respiratory Variables Post-Bariatric Surgery.

Background: Obesity leads to changes in respiratory function, causing reduced lung volumes and mechanical disadvantage of the respiratory muscles. We sought to evaluate the effect of breathing exercises using devices that impose linear and nonlinear load on reversing diaphragm dysfunction and the prevalence of atelectasis after bariatric surgery.

Methods: This was a blind randomized clinical trial.

AIRWAY POSITIVE PRESSURE VS. EXERCISES WITH INSPIRATORY LOADING FOCUSED ON PULMONARY AND RESPIRATORY MUSCULAR FUNCTIONS IN THE POSTOPERATIVE PERIOD OF BARIATRIC SURGERY.

Background: Bariatric surgery can trigger postoperative pulmonary complications due to factors inherent to the procedure, mainly due to diaphragmatic dysfunction.

Aim: To evaluate and compare the effects of two levels of positive pressure and exercises with inspiratory load on lung function, inspiratory muscle strength and respiratory muscle resistance, and the prevalence of atelectasis after gastroplasty.

Methods: Clinical, randomized and blind trial, with subjects submitted to bariatric surgery, allocated to two groups: positive pressure group, who received positive pressure at two levels during one hour and conventional respiratory physiotherapy and inspiratory load group, who performed exercises with load linear inspiratory pressure, six sets of 15 repetitions, in addition to conventional respiratory physiotherapy, both of which were applied twice in the immediate postoperative period and three times a day on the first postoperative day.

Accuracy of total energy expenditure predictive equations after a massive weight loss induced by bariatric surgery.

Background And Aims: Predictive equations remain the clinical tool of choice to estimate the energy expenditure, however, poor accuracy has been found when applied in patients with severe obesity. The aim of this study was to test the accuracy of the total energy expenditure (TEE) those obtained by predictive equations of resting energy expenditure (REE) times individual estimates of metabolic equivalents (MET), taking as reference the TEE measured by doubly labeled water (DLW), before, six and twelve months after bariatric surgery.

Subjects And Methods: Twenty class III obese women (age: 29.

Changes in Physical Activities and Body Composition after Roux-Y Gastric Bypass Surgery.

Purpose: Given the importance of physical activities for health outcomes, it is still unclear whether bariatric surgery per se and the standard care after surgery would result in an increase of physical activity level. This study aimed to determine physical activities preoperatively and at 6 and 12 months postoperatively among female patients who underwent bariatric surgery, and to investigate its relationship with body composition changes.

Material And Methods: Thirty-four women who had Roux-Y gastric bypass (RYGB) surgery completed the study.

Association of 5-HT2C (rs3813929) and UCP3 (rs1800849) gene polymorphisms with type 2 diabetes in obese women candidates for bariatric surgery.

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.

Micronutrient supplementation in gastric bypass surgery: prospective study on inflammation and iron metabolism in premenopausal women.

Background: Low-grade chronic inflammation in morbid obesity is associated with impaired iron metabolism. Bariatric surgery is effective in weight loss; however, it can induce specific nutritional deficiencies, such as iron, especially in premenopausal women. Alternatively, after surgery, there is an improvement in systemic inflammation, raising questions concerning the dosages of micronutrient supplementation.

Analysis of the prevalence of atelectasis in patients undergoing bariatric surgery.

Background And Objective: To observe the prevalence of atelectasis in patients undergoing bariatric surgery and the influence of the body mass index (BMI), gender and age on the prevalence of atelectasis.

Method: Retrospective study of 407 patients and reports on chest X-rays carried out before and after bariatric surgery over a period of 14 months. Only patients who underwent bariatric surgery by laparotomy were included.

[Analysis of the prevalence of atelectasis in patients undergoing bariatric surgery].

Background And Objective: To observe the prevalence of atelectasis in patients undergoing bariatric surgery and the influence of the body mass index (BMI), gender and age on the prevalence of atelectasis.

Method: Retrospective study of 407 patients and reports on chest X-rays carried out before and after bariatric surgery over a period of 14 months. Only patients who underwent bariatric surgery by laparotomy were included.

Gene polymorphisms as a predictor of body weight loss after Roux-en-Y gastric bypass surgery among obese women.

This study aimed to investigate the association between twelve gene polymorphisms and body weight loss, 12 months after Roux-en-Y gastric bypass (RYGB) surgery. Three hundred and fifty-one obese women participated in this study. The statistical software WEKA was used to identify which gene polymorphisms were potential predictors of postoperative percentage of excess weight loss (%EWL).

[Use of positive pressure in pre and intraoperative of bariatric surgery and its effect on the time of extubation].

Background And Objective: to investigate the influence of intraoperative and preoperative airway positive pressure in the time of extubation in patients undergoing bariatric surgery.

Method: Randomized clinical trial, in which 40 individuals with a body mass index between 40 and 55kg/m(2), age between 25 and 55 years, nonsmokers, underwent bariatric surgery type Roux-en-Y gastric bypass by laparotomy and with normal preoperative pulmonary function were randomized into the following groups: G-pre (n = 10): individuals who received treatment with noninvasive positive pressure before surgery for one hour, G-intra (n = 10): individuals who received positive end-expiratory pressure of 10cm H2O throughout the surgical procedure and G-control (n = 20): not received any pre or intraoperative intervention. Following were recorded: time between induction of anesthesia and extubation, between the end of anesthesia and extubation, duration of mechanical ventilation, and time between extubation and discharge from the Post-Anesthetic Recovery.

Ferritin in hypertensive and diabetic women before and after bariatric surgery.

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.
