“…BS appears to be an effective tool for the treatment of obesity and for obesity-related comorbidities, including SAH, DM, dyslipidemia, and cardiovascular events, as well as a means to reduce mortality [6,7,8]. Conservative treatment, diet, and exercise have been established to induce significant weight loss and increase aerobic fitness along with a cardiometabolic benefit [7].…”

Background: Obesity is a pathology with a growing incidence in developing countries. Objective: To evaluate the evolution of cardiometabolic, anthropometrics, and physical activity parameters in individuals undergoing bariatric surgery (BS) in the public healthcare system (PUS) and private healthcare system (PHS). Methods: A longitudinal, observational, and retrospective study was conducted with 111 bariatric patients on two different health systems, with 60 patients from the PUS and 51 from the PHS. Cardiometabolic risk (CR) was analyzed by the assessment of obesity-related comorbidities (AORC) on admission and 3, 6, and 12 months after BS, and the International Physical Activity Questionnaire (IPAQ) was surveyed before and 12 months after BS. In addition, cardiometabolic risk was also assessed by biochemical (fasting glucose and complete lipidogram) and anthropometric (weight, weight loss, waist circumference, and waist-to-height ratio) parameters. Results: On admission, the parameters of severe obesity, systemic arterial hypertension (SAH), Diabetes mellitus (DM), and waiting time to BS were higher in the PUS. Additionally, in the PUS, AORC was reduced only in the SAH parameter. However, in the post-surgery moment, AORC reduced, and there was no difference between the two groups after BS. Regarding physical activity, the IPAQ showed a higher level of activity in the PHS before and one year after BS. Conclusion: At the PUS, BS is performed in patients with a higher degree of comorbidities, but BS improved the reduction of the CR at a similar level to those observed in the PHS.

“…Morbid obesity is frequently associated with concomitant diseases, including hypertension, diabetes, coronary arterial disease, cholecystic diseases, hepatic fibrosis and fatty degeneration of the liver, dyslipidaemia, osteoarthritis and certain neoplasms. These diseases contribute to both significant deterioration of health condition and premature death [ 7 ]. Studies performed in a population of 900 thousand adults demonstrated that obesity reduces life expectancy by 2 to 4 years, whereas morbid obesity reduces it by up to 10 years [ 8 ].…”

IntroductionOverweight and obesity are ranked in the fifth place among the risk factors responsible for the greatest number of deaths in the world.AimTo assess the effects of treatment of patients with morbid obesity using endoscopic intragastric balloon (IGB) implantation.Material and methodsTwo hundred and seventy-two patients with obesity were treated using endoscopic intragastric balloon implantation. Upon analysis of the inclusion and exclusion criteria, the study covered a group of 63 patients with morbid obesity. The patients were implanted with the LexBal balloon. Reduction of excess body mass, changes to BMI values and ailments and complications divided into mild and severe were assessed.ResultsBefore intragastric balloon treatment, the average body mass index (BMI) value was 58.3 ±10.5 kg/m2, whereas after 6 months of treatment it decreased to 49.5 ±8.7 kg/m2. The patients with postoperative BMI equal to or greater than 50.0 kg/m2 reported nausea (69.7%), vomiting (51.5%), flatulence (45.5%), upper abdominal pain (36.4%) and general discomfort (424%) more frequently. Dehydration (9.1%) was also more frequent in this group, whereas frequency of occurrence of such ailments and complications as heartburn (23.3%) and oesophageal candidiasis (10.0%) was higher in the patients with postoperative BMI below 50.0 kg/m2.ConclusionsEndoscopic intragastric balloon implantation is an effective and safe method of excess body mass reduction in patients with morbid obesity before a planned bariatric surgical procedure. Pre-operative excess body mass and BMI value and post-operative excess weight loss in patients with morbid obesity have no impact on frequency of occurrence of ailments and complications in IGB treatment.

“…In the case of severe obesity, bariatric surgery has been the best alternative treatment. Brazil's Sistema Único de Saúde (SUS, Brazilian Unified Health System) provides this surgical procedure, but the number of surgeries performed is still insufficient [4,5], resulting in a long waiting period, which can last from three to seven years [5,6]. The reduction of 5 to 10% of body weight before bariatric surgery decreases the surgical complications and comorbidities associated with obesity, and in some cases may prevent surgery through the adoption of new habits [4,7,8].…”

Randomized controlled trial protocol: A quanti-quali approach for analyzing the results of an intervention on the waiting list for bariatric surgery

Objective This article aims to describe the protocol of a randomized clinical trial and the baseline results of the study of a one-year interdisciplinary intervention in users of the public health system in the bariatric surgery waiting list. Methods A randomized, single-blind clinical trial will be conducted including 88 participants recruited on an outpatient clinic of the public health system. Participants were randomized into the control group (n=44), receiving the usual treatment; and into the intervention group (n=44), participating in the educational intervention. Participants had their food intake, negative affectivity and physical inactivity/sedentary behavior assessed, as well as anthropometric and body composition measurements; their blood samples were collected; and also had different physical capacity tests. Results Of the 157 participants invited, 27 had severe functional limitations, one was under-age, and four declined the study due to associated diseases. Eighty-eight participants were randomized: 44 for the Control Group and 44 for the Intervention Group. When comparing the demographic and biochemical characteristics, there were no differences between groups except for serum glucose (GC=110.4±46.8mg/dL and GI93.1±16.9mg/dL, p=0.039). Conclusion This study protocol describes the methodology used in the study of educational intervention for the promotion of health care of patients on the waiting list for bariatric surgery. It shows that there is similarity between the baseline comparison groups. Registro Brasileiro de Ensaios Clínicos (Brazilian Clinical Trials Registry), RBR-775y3d.
