Relationship of Food Intolerance 2 Years After Roux-en-Y Gastric Bypass Surgery for Obesity with Masticatory Efficiency and Protein Consumption

Translation and cross cultural adaptation of the questionnaire "Quality of Alimentation" for brazilian portuguese

PURPOSE

We aimed to provide translation and cultural adaptation of the questionnaire "Quality of Alimentation" from English to Brazilian Portuguese.

METHODS

The transcultural translation process consisted of the following steps: translation of the original English version to Portuguese by two bilingual translators native in the targeted language; Reverse translation by two translators native in the original language; Review of reverse translation; Review of the Portuguese version from the questionnaire by a local committee of experts in bariatric surgery; Pre-trial to evaluate of clarity, comprehension, and overall acceptability by the target population.

RESULTS

In its final Portuguese version, the questionnaire "Quality of alimentation" was found to be of clear comprehension and easy applicability.

CONCLUSION

The questionnaire's translation and cultural adaptation for Brazilian Portuguese represents an important step towards improving food tolerance evaluation following bariatric surgery. Further studies are however necessary for validation of its psychometric properties in Brazil.

Bariatric surgery and mental health outcomes: an umbrella review

AIMS

To evaluate the breadth, depth and effectiveness of the evidence quality of all existing studies on bariatric surgery and mental health outcomes.

DESIGN

Umbrella review of existing Systematic review and meta-analyses.

DATA SOURCES

PubMed, Embase, Web of Science, and the Cochrane Liberally databases of Systematic review and meta-analyses, and hand searching the reference lists of eligible publications.

RESULTS

The search identified nine studies and 20 mental health outcomes from 1251 studies. Evidence shows that bariatric surgery is associated with significant improvement in areas such as anxiety, depression and eating disorders (including binge-eating disorder), and there is a significant harmful association with suicide, self-harm and alcohol use disorder (AUD). Among them, the most studied outcome is depression (4 articles). High-quality evidence proves that the score of depressive symptoms can be significantly improved after bariatric surgery within a two-year follow-up period and is not affected by the follow-up time. Low-quality evidence shows that bariatric surgery can significantly reduce depressive symptoms regardless of age and BMI, with an odds ratio (OR) of 0.49. Regardless of the postoperative BMI, the anxiety symptoms of women over 40 still decreased significantly, with an OR of 0.58. Regardless of the type of surgery, surgery can significantly reduce the incidence of eating disorders and symptoms. However, there is no obvious change in the follow-up time of AUD in the first two years after bariatric surgery, and the risk increases obviously in the third year, with an OR of 1.825. The evidence of moderate research shows that the risk of suicide and self-harm increases after bariatric surgery. The odds ratios in the same population and the control group were 1.9 and 3.8 times, respectively.

CONCLUSION

Bariatric surgery is beneficial for improving most mental health-related outcomes. However, we should be cautious about the increased risk of adverse mental health after surgery, such as suicide, self-harm, and AUD.

FOOD TOLERANCE AND NUTRITIONAL RISK AFTER SLEEVE GASTRECTOMY AND ROUX-EN-Y GASTRIC BYPASS IN ELDERLY PATIENTS WITH SEVERE OBESITY: A PROSPECTIVE, RANDOMIZED CONTROLLED TRIAL

BACKGROUND

Bariatric surgery is still controversial in elderly patients with severe obesity. Most publications focus on safety and early clinical outcomes. Food tolerance and nutritional postoperative risk is unknown for this population.

METHODS

Thirty-six elderly patients with severe obesity were recruited for an open-label randomized trial from September 2017 to May 2019 comparing laparoscopic sleeve gastrectomy (LSG) to Roux-en-Y Gastric Bypass (LRYGB). Food tolerance was accessed by Quality of Alimentation (QoA) questionnaire and data on weight loss, body composition, and nutritional risk were collected between 6 and 24 months after surgery.

RESULTS

Comparing LSG to LRYGB patients, the latter had higher total weight loss (22% vs 31%, P=0.01) and excess weight loss (53% vs 68%, P=0.01). Food tolerance to eight food groups was similar between groups (14 vs 15 points, P=0.270), as Suter score (23 vs 25, P=0.238). Daily protein intake was below recommendation in both groups (40 vs 51 g/d, P=0.105). Nutritional risk, evaluated through Standardized Phase Angle (-1.48 vs -1.99, P=0.027), was worse for LRYGB group.

CONCLUSION

Food tolerance and adequacy of food consumption were similar in both groups. LRYGB patients had higher nutritional risk.

Nutritional Inadequacies Among Post-bariatric Patients During COVID-19 Quarantine in Sao Paulo, Brazil

Post bariatric control of food intake is influenced by psychological and behavioral factors. We investigated dietary habits and food intake during COVID-19 quarantine among recently operated patients. Patients were assessed for total and per meal energy and macronutrient intake as well as frequency of food consumption per processing level. Patients were also classified according to adherence to nutritional recommendations from our outpatient clinic. Main results are indicative of inappropriate nutritional intake during COVID-19 quarantine in postoperative bariatric patients. We observed that many patients failed to meet the recommended protein intake (89.2%) along a relatively high intake of ultra-processed foods (~1/4 of the diet). Our data suggest the need for the implementation of strategies to extend nutritional care to at-risk patients during social distancing.
