Abstract Purpose The treatment of people with severe obesity and BMI > 50 kg/m2 is challenging. The present study aims to evaluate the short and mid-term outcomes of one anastomosis gastric bypass (OAGB) with a biliopancreatic limb of 150 cm as a primary bariatric procedure to treat those people in a referral center for bariatric surgery. Material and Methods Data of patients who underwent OAGB for severe obesity with BMI > 50 kg/m2 between 2010 and 2017 were collected prospectively and analyzed retrospectively. Follow-up comprised clinical and biochemical assessment at 1, 3, 6, 12, 18, and 24 months postoperatively, and once a year thereafter. Results Overall, 245 patients underwent OAGB. Postoperative mortality was null, and early morbidity was observed in 14 (5.7%) patients. At 24 months, the percentage total weight loss (%TWL) was 43.2 ± 9, and percentage excess weight loss (%EWL) was 80 ± 15.7 (184 patients). At 60 months, %TWL was 41.9 ± 10.2, and %EWL was 78.1 ± 18.3 (79 patients). Conversion to Roux-en-Y gastric bypass was needed in three (1.2%) patients for reflux resistant to medical treatment. Six patients (2.4%) had reoperation for an internal hernia during follow-up. Anastomotic ulcers occurred in three (1.2%) patients. Only two patients (0.8%) underwent a second bariatric surgery for insufficient weight loss. Conclusion OAGB with a biliopancreatic limb of 150 cm is feasible and associated with sustained weight loss in the treatment of severe obesity with BMI > 50 kg/m2. Further randomized studies are needed to compare OAGB with other bariatric procedures in this setting. Graphical abstract

BACKGROUND: Along with the augmentation in obesity rates in recent years, the demand for bariatric surgery has startlingly increased. Nutritional counseling in the preoperative period is very important because it contributes to higher success rate in the post-operative period. AIM: To assess the nutritional status of patients in a multidisciplinary program for the treatment of severe obesity and pre-operatively for bariatric surgery, characterizing the consumption of healthy nutrients. METHODS: A retrospective analysis of 30 patients was conducted. Personal information, anthropometric data and dietary assessment by 24-hour food record were collected. The analysis of energy intake was performed in Dietpro 5.1 Professional(r) program. The statistical treatment of the caloric intake was performed by an ANOVA test with Bonferroni´s post hoc and for anthropometric data the paired t test was used. RESULTS: From the total, 73% of the patients were women and 27% male, mean age was 48.4+12.9 and 49.8+8.1, respectively. A lower weight in the 5th appointment was observed when compared with the 1st one. There was a reduction in caloric intake in the 2nd, 3rd, 4th and 5th appointments when compared with the 1st. It was observed that in the 5th appointment more than 50% of the patients underwent six meals a day. There was an increase in the consumption of fruit along the appointments and 72.2% of patients consumed 1-2 servings of fruit a day. Vegetables intake was high in all appointments in the pre-operative period and, although low, the whole grain products consumption has increased during the pre-operative period achieving 30% of the study population. CONCLUSION: There was a decrease in body weight, a trend in the decrease of the body mass index and waist circumference and quantitative and qualitative improvement of food consumption.

1.AbstractBackgroundMetabolic disorders associated with obesity could lead to alterations in brain structure and function. Whether these changes can be reversed after weight loss is unclear. Bariatric surgery provides a unique opportunity to address these questions because it induces marked weight loss and metabolic improvements which in turn may impact the brain in a longitudinal fashion. Previous studies found widespread changes in grey matter (GM) and white matter (WM) after bariatric surgery. However, findings regarding changes in spontaneous neural activity following surgery, as assessed with the fractional amplitude of low frequency fluctuations (fALFF) and regional homogeneity of neural activity (ReHo), are scarce and heterogenous. In this study, we used a longitudinal design to examine the changes in spontaneous neural activity after bariatric surgery (comparing pre- to post-surgery), and to determine whether these changes are related to cardiometabolic variables.MethodsThe study included 57 participants with severe obesity (mean BMI=43.1±4.3kg/m2) who underwent sleeve gastrectomy (SG), biliopancreatic diversion with duodenal switch (BPD), or Roux-en-Y gastric bypass (RYGB), scanned prior to bariatric surgery and at follow-up visits of 4 months (N=36), 12 months (N=29), and 24 months (N=14) after surgery. We examined fALFF and ReHo measures across 1022 cortical and subcortical regions (based on combined Schaeffer-Xiao parcellations) using a linear mixed effect model. Voxel-based morphometry (VBM) based on T1-weighted images was also used to measure GM density in the same regions. We also used an independent sample from the Human Connectome Project (HCP) to assess regional differences between individuals who had normal-weight (N=46) or severe obesity (N=46).ResultsWe found a global increase in the fALFF signal with greater increase within dorsolateral prefrontal cortex, precuneus, inferior temporal gyrus, and visual cortex. This effect was more significant 4 months after surgery. The increase within dorsolateral prefrontal cortex, temporal gyrus, and visual cortex was more limited after 12 months and only present in the visual cortex after 24 months. These increases in neural activity measured by fALFF were also significantly associated with the increase in GM density following surgery. Furthermore, the increase in neural activity was significantly related to post-surgery weight loss and improvement in cardiometabolic variables, such as insulin resistance index and blood pressure. In the independent HCP sample, normal-weight participants had higher global and regional fALFF signals, mainly in dorsolateral/medial frontal cortex, precuneus and middle/inferior temporal gyrus compared to the obese participants. These BMI-related differences in fALFF were associated with the increase in fALFF 4 months post-surgery especially in regions involved in control, default mode and dorsal attention networks.ConclusionsBariatric surgery-induced weight loss and improvement in metabolic factors are associated with widespread global and regional increases in neural activity, as measured by fALFF signal. These findings alongside the higher fALFF signal in normal-weight participants compared to participants with severe obesity in an independent dataset suggest an early recovery in the neural activity signal level after the surgery.
