“…However, although bariatric Cristina Segura-Garcia, Matteo Aloi and Marianna Rania are joint first authors. surgery seems to be the most effective treatment for obesity, some individuals do not respond adequately, especially in the long-term evaluation [7]. Furthermore, specific subgroups of patients with obesity may report persistent or de novo pathological eating behaviors even after bariatric surgery [8].…”

Introduction Obesity is a major health problem with an increasing risk of mortality, associated with comorbidities and high rates of dropout. Research demonstrated that pathological eating behaviors could help to phenotype obese patients thus tailoring clinical interventions. Therefore, our aim was to develop (study 1), validate (study 2), and test in a clinical setting (study 3) the Eating Behaviors Assessment for Obesity (EBA-O). Method Study 1 included the exploratory factor analysis (EFA) and McDonald's ω in a general population sample (N = 471). Study 2 foresaw the confirmatory factor analysis (CFA) and convergent validity in 169 participants with obesity. Study 3 tested the capability of the EBA-O to characterize eating behaviors in a clinical sample of 74 patients with obesity. Results Study 1. EFA identified five factors (i.e., food addiction, night eating, binge eating, sweet eating, and prandial hyperphagia), explaining 68.3% of the variance. The final EBA-O consisted of 18 items. McDonald's ω ranged between 0.80 (hyperphagia) and 0.92 (binge eating), indicating very good reliability. Study 2. A second-order five-factor model, through CFA, showed adequate fit: relative chi-square (χ 2 /df) = 1.95, CFI = 0.93, TLI = 0.92, RMSEA = 0.075, and SRMR = 0.06, thus suggesting the appropriateness of the EBA-O model. Significant correlations with psychopathological questionnaires demonstrated the convergent validity. Study 3. Significant associations between EBA-O factors and emotional-related eating behaviors emerged. ConclusionThe EBA-O demonstrated to be a reliable and easy-to-use clinical tool to identify pathological eating behaviors in obesity, particularly useful for non-experts in eating disorders. Level of evidence Level V, descriptive research.

Objective: Although controversial, there may be a positive correlation between the body mass index (BMI) of individuals with obesity in euthyroidism and serum levels of thyroid stimulating hormone (TSH). This study aimed to evaluate the correlation between BMI and serum levels of TSH in individuals with morbid obesity undergoing bariatric surgery. Patients and methods: The medical records of patients treated between the years 2012 and 2016 were used. A total of 96 patients with obesity, pre-surgery BMI ≥ 40 kg/m2, being followed up in the endocrinology unit, with mean age of 50 years, were evaluated pre and post operatively. In addition to the plasma TSH dosage by IRMA and plasma free T4 by RIE, age, BMI and biochemical parameters (glycaemia, total cholesterol and triglycerides) were analyzed. Results: Patients with BMI > 40 kg/m2 prior to surgery showed higher serum TSH than subjects with a BMI <40 kg/m after surgery (2.48 ± 0.2 vs. 1.81 ± 0.25, p < 0.001). The decrease in BMI was accompanied by an improvement in the glycemic and lipid profiles, as well as free T4 and TSH levels are shown to accompany BMI. Conclusion: Bariatric surgery was efficient in controlling obesity, since 100% of the patients had their degree of obesity decreased with concomitant metabolic improvement. We found that BMI and TSH are positively related, as post-surgical patients had both BMI and TSH decreased.

“…For each bariatric technique, BMI, %EBL, FM, FFM and TBW were analyzed at each time interval by one-way analysis of variance (ANOVA). In addition, based on several reports of decrease in efficacy of RYGB and SG on %EBL and body composition from one-year post-op onwards [ 6 , 37 , 38 ], the difference between values registered at 2 and 5 years was also calculated. Since a high proportion of subjects was unavailable after 3 years, we performed two analyses, one for the whole cohort of 565 subjects, the other for the 180 subjects who attended the annual body composition assessment for 5 years.…”

Biliopancreatic Diversion (BPD), Long Common Limb Revisional Biliopancreatic Diversion (BPD + LCL–R), Roux-en-Y Gastric Bypass [RYGB] and Sleeve Gastrectomy (SG) mediate differential quantitative changes in body weight and qualitative modifications in body composition: a 5-year study

Aims Bariatric surgeries induce profound weight loss (decrease in body mass index, BMI), through a decrease in fat mass (FM) and to a much lesser degree of fat-free mass (FFM). Some reports indicate that the weight which is lost after gastric bypass (RYGB) and sleeve gastrectomy (SG) is at least partially regained 2 years after surgery. Here we compare changes in BMI and body composition induced by four bariatric procedures in a 5 years follow-up study. Methods We analyzed retrospectively modifications in BMI, FM and FFM obtained through Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), biliopancreatic diversion (BPD) and a long common limb revisional biliopancreatic diversion (reduction of the gastric pouch and long common limb; BPD + LCL−R). Patients were evaluated at baseline and yearly for 5 years. Of the whole cohort of 565 patients, a subset of 180 patients had all yearly evaluations, while the remaining had incomplete evaluations. Setting University Hospital. Results In a total of 180 patients evaluated yearly for 5 years, decrease in BMI and FM up to 2 years was more rapid with RYGB and SG than BPD and BPD + LCL−R; with RYGB and SG both BMI and FM slightly increased in the years 3–5. At 5 years, the differences were not significant. When analysing the differences between 2 and 5 years, BPD + LCL−R showed a somewhat greater effect on BMI and FM than RYGB, BPD and SG. Superimposable results were obtained when the whole cohort of 565 patients with incomplete evaluation was considered. Conclusions All surgeries were highly effective in reducing BMI and fat mass at around 2 years; with RYGB and SG both BMI and FM slightly increased in the years 3–5, while BPD and BPD + LCL−R showed a slight further decreases in the same time interval.
