ABSTRACT
PURPOSE OF REVIEW: This review explores characterizing candidates for obesity treatments including pharmacotherapy, endoscopic bariatric therapies, and metabolic bariatric surgery (MBS), focusing on established clinical parameters for diagnosing obesity beyond body mass index alone. RECENT FINDINGS: Existing literature primarily provides rates for fat mass percentage (i.e., a marker for adiposity quantity), waist circumference (i.e., a marker for adiposity distribution), and C-reactive protein levels (i.e., a marker for adiposity functionality) among obesity treatment candidates. Limited data on abnormal values and sex-based differentiation exist. The literature indicates high central-tendency measures for fat mass percentage and waist circumference, while C-reactive protein levels vary. Data on the Edmonton Obesity Staging System (i.e., a marker for adiposity-related disease severity) is predominantly available for MBS candidates. Future studies in obesity interventions should improve screening and diagnosis of obesity by incorporating sex-specific considerations and providing abnormal value rates for measurements to enhance understanding of patients' characteristics.

BACKGROUND: Weight bias toward people with obesity (PwO) is common in healthcare settings. Efforts to address weight bias in healthcare settings should begin during university studies. This study aimed to explore the effect of a multifaceted intervention on weight bias among undergraduate healthcare students. METHODS: An open label randomized controlled trial. The intervention tool consisted of short video lectures on obesity, vignettes simulating interactions between health professionals and PwO, and open discourse with a PwO. The control group received a short-written document on obesity. Online questionnaires on Anti-Fat Attitudes ('AFA'), short form of the Fat-Phobia Scale ('FPS'), Weight Implicit Association Test ('Weight-IAT'), and knowledge about obesity were administered at baseline, 1-week, and 6-week post-intervention. RESULTS: A total of 162, 152, and 146 students participated in the study at baseline, 1-week, and 6-week post-intervention, respectively. Their mean age was 25.8 ± 6.7 years and 88.3% were women. Means of AFA total scores and FPS scores decreased significantly over time only within the intervention group (P Time*Group = 0.002 and 0.014). Both groups showed a similar trend over time in mean scores of Weight-IAT (P Time*Group = 0.868) and knowledge about obesity (P Time*Group = 0.115). CONCLUSIONS: A multifaceted intervention resulted in a significant reduction in explicit weight bias but did not yield any additional advantages over the control group in implicit weight bias and knowledge about obesity.

BACKGROUND: One-anastomosis gastric bypass (OAGB) is an emerging metabolic bariatric surgery (MBS) type used in both primary OAGB (pOAGB) and revisional OAGB (rOAGB). We studied ≤30-day outcomes of pOAGB and rOAGB and identified predictors of early complications. METHODS: Electronic medical records of all OAGBs performed between January 2017 and December 2021 at a high-volume bariatric clinic in Israel comprising four hospital centers were scanned retrospectively using specialized data software (MDClone software, version 6.1). Data gathered were patients' characteristics, surgical procedure, and ≤30-day complications with Clavien-Dindo Classification (CDC). Multivariate logistic regression analyses were used to identify factors related to early complications of pOAGB and rOAGB. RESULTS: A total of 6722 patients underwent a pOAGB (n = 5088, 75.7%) or rOAGB (n = 1634, 24.3%) procedure at our institution. Preoperative mean age and body mass index (BMI) were 40.6 ± 11.5 years and 41.2 ± 4.6 kg/m2, respectively. Early complications occurred in 258 (3.8%) patients (176 pOAGB and 82 rOAGB) and included mainly bleeding (n = 133, 2.0%), leaks (n = 31, 0.5%), and obstruction/strictures (n = 19, 0.3%). CDC complications for grades 1-2 and grades 3a--5 were 1.5% and 1.6%, respectively. The overall mortality rate was 0.03% (n = 2). Age, operative time ≥3 h, and any additional concomitant procedure were independent predictors of early complications following pOAGB, while a diagnosis of diabetes mellitus and operative time ≥3 h were independent predictors of early complications following rOAGB. CONCLUSIONS: OAGB was found to be a safe primary and revisional MBS procedure in the ≤30-postoperative day term. The most common complications were gastrointestinal bleeding, leaks, and obstruction/stricture.
ABSTRACT
OBJECTIVES: To describe gastrointestinal-related side-effects reported following the One Anastomosis Gastric Bypass (OAGB). METHODS: A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) who were recruited to the study based on time elapsed since surgery was performed. An online survey with information on demographics, anthropometrics, medical conditions, and gastrointestinal outcomes was administered in both countries simultaneously. RESULTS: Respondents from Israel (pre-surgery age of 41.6 ± 11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6 ± 12.3 years, 79.3% females) presented mean excess weight loss of 51.0 ± 19.9 and 62.4 ± 26.5%, 89.0 ± 22.0 and 86.2 ± 21.4%, and 89.9 ± 23.6 and 98.2 ± 20.9% (P < 0.001 for both countries), at 1-6 months, 6-12 months, and 1-5 years post-surgery, respectively. Median Gastrointestinal Symptom Rating Scale score was similar between time elapsed since surgery groups among respondents from Israel and Portugal (≤1.97 and ≤2.12). A notable proportion of respondents from Israel and Portugal at all time points reported 1-3 bowel movements per day (≤62.8 and ≤87.6%), Bristol stool scale categories which represent diarrhea-like stools (≤51.9 and ≤56.3%), having discomfort due to flatulence (≤79.4 and ≤90.2%), and mild to severe dyspepsia symptoms (≤50.5 and ≤73.0%). CONCLUSIONS: A notable proportion of OAGB patients might experience certain gastrointestinal symptoms postoperatively, including flatulence, dyspepsia, and diarrhea-like stools.

This study aimed to describe nutritional and lifestyle parameters following one-anastomosis gastric bypass (OAGB). A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) was performed. Patients were approached according to the time elapsed since surgery. An online survey with information regarding demographics, anthropometrics, and nutritional and lifestyle aspects was administered in both countries simultaneously. Respondents from Israel (pre-surgery age of 41.6 ± 11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6 ± 12.3 years, 79.3% females) reported changes in their appetite (≤94.0% and ≤94.6%), changes in their taste (≤51.0 and ≤51.4%), and intolerance to specific foods (i.e., red meat, pasta, bread, and rice). Bariatric surgery-related eating recommendations were generally followed well, but a trend toward lower adherence was evident in groups with longer time elapsed since surgery in both countries. Most respondents from Israel and Portugal reported participation in follow-up meetings with a surgeon (≤94.0% and 100%) and a dietitian (≤92.6% and ≤100%), while far fewer reported participation in any follow-up meeting with a psychologist/social worker (≤37.9% and ≤56.1%). Patients following OAGB might experience changes in appetite, taste, and intolerance to specific foods. Adherence to bariatric surgery-related eating recommendations is not always satisfying, especially in the longer term post-surgery.

BACKGROUND: Long-term laparoscopic sleeve gastrectomy (LSG) outcomes in patients with obesity are scarce. We aimed to examine the outcomes and subjective experience of patients who underwent primary LSG with long-term follow-up. METHODS: The study is a retrospective observational analysis of patients who underwent primary LSG in a single center with 5-15 years of follow-up. Patients' hospital chart data supplemented by a detailed follow-up online questionnaire and telephone interview were evaluated. RESULTS: The study sample included 578 patients (67.0% female) with 8.8 ± 2.5 years of mean follow-up, with a response rate to the survey of 82.8%. Mean baseline age and body mass index (BMI) were 41.9 ± 10.6 years and 42.5 ± 5.5 kg/m2, respectively. BMI at nadir was 27.5 ± 4.9 kg/m2, corresponding to a mean excess weight loss (EWL) of 86.9 ± 22.8%. Proportion of patients with weight regain, defined as nadir ≥ 50.0% EWL, but at follow-up < 50.0% EWL, was 34.6% (n = 200) and the mean weight regain from nadir was 13.3 ± 11.1 kg. BMI and EWL at follow-up were 32.6 ± 6.4 kg/m2 and 58.9 ± 30.1%, respectively. The main reasons for weight regain given by patients included "not following guidelines," "lack of exercise," "subjective impression of being able to ingest larger quantities of food in a meal," and "not meeting with the dietitian." Resolution of obesity-related conditions at follow-up was reported for hypertension (51.7%), dyslipidemia (58.1%) and type 2 diabetes (72.2%). The majority of patients (62.3%) reported satisfaction with LSG. CONCLUSIONS: In the long term, primary LSG was associated with satisfactory weight and health outcomes. However, weight regain was notable.

BACKGROUND: Bariatric and Metabolic Surgery (BMS) is a popular weight loss intervention worldwide, yet few scientific studies have examined variations in preoperative practices globally. This study aimed to capture global variations in preoperative practices concerning patients planned for BMS. METHODS: A 41-item questionnaire-based survey was designed and the survey link was freely distributed on social and scientific media platforms, email groups and circulated through personal connections of authors. The survey included eight parts: basic information; criteria for BMS; preoperative nutritional screening; preoperative weight loss; preoperative diets for liver size reduction; preoperative glycemic control; other laboratory investigations and preparations; decision making, education, and consents. Descriptive statistics were used to analyse data and graphs were used for representation where applicable. RESULTS: Six hundred thirty-four bariatric healthcare professionals from 76 countries/regions completed the survey. Of these, n = 310 (48.9%) were from public hospitals, n = 466 (73.5%) were surgeons, and the rest were multidisciplinary professionals. More than half of respondents reported using local society/association guidelines in their practice (n = 310, 61.6%). The great majority of respondents routinely recommend nutritional screening preoperatively (n = 385, 77.5%), mandatory preoperative diets for liver size reduction (n = 220, 53.1%), routine screening for T2DM (n = 371, 90.7%), and mandate a glycemic control target before BMS in patients with T2DM (n = 203, 55.6%). However, less than half (n = 183, 43.9%) recommend mandatory preoperative weight loss to all patients. Most respondents (n = 296, 77.1%) recommend psychological intervention before surgery for patients diagnosed with psychological conditions. Variations were also identified in laboratory investigations and optimisation; and in the aspects of decision making, education and consent. CONCLUSIONS: This survey identified significant global variations in preoperative practices concerning patients seeking primary BMS. Our findings could facilitate future research for the determination of best practice in these areas of variations, and consensus-building to guide clinical practice while we wait for that evidence to emerge.

BACKGROUND: Emerging evidence suggest that problematic eating behaviors such as food addiction (FA) and binge eating (BE) may alter following bariatric surgery (BS) and impact weight outcomes. We aimed to examine the prevalence of FA and BE and their associations with weight outcomes 2 years post-sleeve gastrectomy (SG). METHODS: Forty-five women (mean age 32.4 ± 10.9 years) who underwent SG and completed 24 months of follow-up were evaluated prospectively at pre-, 3-, 6-, 12-, and 24-month post-SG. Data collected included anthropometrics, nutritional intake, and lifestyle patterns. The Yale Food Addiction Scale (YFAS) and the Binge Eating Scale (BES) were used to characterize FA and BE, respectively. RESULTS: Pre-surgery FA and BE were identified in 40.0% and 46.7% of participants, respectively. Following SG, FA and BE prevalence was 10.0%, 5.0%, 29.4%, and 14.2% (P = 0.007), and 12.5%, 4.9%, 18.4%, and 19.4% (P < 0.001) at 3, 6, 12, and 24 months, respectively. Women with BE at baseline gained significantly more weight from the nadir compared to non-BE women at baseline (P = 0.009). There was no relationship between FA at baseline and weight (P = 0.090). Weight regained from the nadir positively correlated with BES scores at baseline (r = 0.374, P = 0.019). CONCLUSIONS: FA and BE tend to decrease during the early postoperative period, but remains in a notable rates return by 2 years post-SG. Moreover, pre-surgical BE was related to higher weight-regain. Proper management pre-BS should include a comprehensive eating pathologies assessment, as these pathologies may remain or re-emerge post-surgery and lead to worse weight outcomes.

INTRODUCTION: Weight bias, stigma, and discrimination are common among healthcare professionals. We aimed to evaluate whether an online education module affects weight bias and knowledge about obesity in a private medical center setting. METHODS: An open-label randomized controlled trial was conducted among all employees of a chain of private medical centers in Israel (n = 3,290). Employees who confirmed their consent to participate in the study were randomized into intervention or control (i.e., "no intervention") arms. The study intervention was an online 15-min educational module that included obesity, weight bias, stigma, and discrimination information. Questionnaires on Anti-Fat Attitudes (AFA), fat-phobia scale (F-scale), and beliefs about the causes of obesity were answered at baseline (i.e., right before the intervention), 7 days, and 30 days post-intervention. RESULTS: A total of 506, 230, and 145 employees responded to the baseline, 7-day, and 30-day post-intervention questionnaires, respectively. Mean participant age was 43.3 ± 11.6 years, 84.6% were women, and 67.4% held an academic degree. Mean F-scale scores and percentage of participants with above-average fat-phobic attitudes (≥3.6) significantly decreased only within the intervention group over time (p ≤ 0.042). However, no significant differences between groups over time were observed for AFA scores or factors beliefs to cause obesity. CONCLUSIONS: A single exposure to an online education module on weight bias and knowledge about obesity may confer only a modest short-term improvement in medical center employees' fat-phobic attitudes toward people with obesity. Future studies should examine if reexposure to such intervention could impact weight bias, stigma, and discrimination among medical center staff in the long-term.

One anastomosis gastric bypass (OAGB) is an emerging bariatric procedure, yet data on its effect on the gastrointestinal tract are lacking. This study sought to evaluate the incidence of small-intestinal bacterial overgrowth (SIBO) following OAGB; explore its effect on nutritional, gastrointestinal, and weight outcomes; and assess post-OABG occurrence of pancreatic exocrine insufficiency (PEI) and altered gut microbiota composition. A prospective pilot cohort study of patients who underwent primary-OAGB surgery is here reported. The pre-surgical and 6-months-post-surgery measurements included anthropometrics, glucose breath-tests, biochemical tests, gastrointestinal symptoms, quality-of-life, dietary intake, and fecal sample collection. Thirty-two patients (50% females, 44.5 ± 12.3 years) participated in this study, and 29 attended the 6-month follow-up visit. The mean excess weight loss at 6 months post-OAGB was 67.8 ± 21.2%. The glucose breath-test was negative in all pre-surgery and positive in 37.0% at 6 months (p = 0.004). Positive glucose breath-test was associated with lower reported dietary intake and folate levels and higher vitamin A deficiency rates (p ≤ 0.036). Fecal elastase-1 test (FE1) was negative for all pre-surgery and positive in 26.1% at 6 months (p = 0.500). Both alpha and beta diversity decreased at 6 months post-surgery compared to pre-surgery (p ≤ 0.026). Relatively high incidences of SIBO and PEI were observed at 6 months post-OAGB, which may explain some gastrointestinal symptoms and nutritional deficiencies.

BACKGROUND: The use of one anastomosis gastric bypass (OAGB) has increased in recent years. However, the efficacy and safety outcomes of this procedure remain under debate. Here, we compare our early outcome and mid-term safety of OAGB with primary Roux-en-Y gastric bypass (RYGB). METHODS: This was a retrospective study using computerized electronic medical records data of patients who underwent RYGB or OAGB as a primary procedure from February 2012 to February 2019 in our bariatric center. Data collected included demographics, weight-outcomes, adverse events, hospital readmission, reoperation rates, and mortality following both procedures. RESULTS: A total of 314 patients were included (132 RYGB and 182 OAGB). Operative time and costs were significantly lower for OAGB (80 vs. 125 min, p<0.01 and 2018.8 vs. 2912.3 USD, p < 0.01, respectively), but length of hospital stay was longer (4.06 ± 0.67 days vs. 3.58 ± 0.79, p < 0.0001). At 12 months post-surgery, the percentage of excess body mass index loss was comparable between the two groups, but the change in body mass index (BMI) was significantly higher in the OAGB group. Early (< 30 days) and late (> 30 days) surgical adverse events were also similar between the two groups. CONCLUSION: Comparable short- and mid-term outcomes and adverse events are found for primary OAGB and RYGB. OAGB is not inferior to RYGB as a primary bariatric procedure for the treatment of obesity.

BACKGROUND: The appropriate strategies to minimize skeletal deterioration following bariatric surgeries are inconclusive. This randomized controlled trial evaluated the effect of preoperative vitamin supplementation on bone mineral density (BMD) and biochemical parameters in females post-sleeve gastrectomy (SG). METHODS: Participants were randomized to a 2-month preoperative treatment with a multivitamin and vitamin D 4000 IU/d (intervention arm) or 1200 IU/d (control arm). Preoperative and 12-month postoperative follow-up evaluations included anthropometrics, biochemical parameters, and dual energy X-ray absorptiometry (DEXA). RESULTS: Sixty-two females (median age 29.7 years and median BMI 43.4 kg/m2) were recruited, 87% completed the 12-month follow-up. For the intervention and control arms, significant and similar reductions at 12-months post-surgery were observed in BMD of the hip (-6.8 ± 3.7% vs. -6.0 ± 3.6%; P = 0.646) and of the femoral neck (-7.1 ± 5.8% vs. -7.2 ± 5.5%; P = 0.973). For the intervention compared to the control arm, the 25 hydroxyvitamin D (25(OH)D) increment was greater after 2 months treatment, and vitamin D deficiency rates were lower at 3 and 6-months follow-up (P < 0.016). However, at 12-months postoperative, 25(OH)D values and vitamin D deficiency were comparable between the arms (P > 0.339). Predictors for BMD decline in the total hip were the percentage of excess weight-loss, age>50 years, and lower initial BMI (P ≤ 0.003). CONCLUSIONS: SG was associated with a significant decline in BMD of the hip and femoral neck in young and middle-aged women, and was unaffected by preoperative vitamin D supplementation. Females who are peri-menopausal or with greater postoperative weight-loss should be particularly followed for BMD decline.

INTRODUCTION: Sleeve gastrectomy (SG) is an established bariatric procedure. However, long-term data on eating and lifestyle behaviors and their effect on weight outcomes are scarce. Therefore, this study aimed to examine these long-term behaviors and their associations to weight outcomes following SG. METHODS: A long-term follow-up study (>5 years post-surgery) of 266 adult patients admitted to a primary SG surgery during 2008-2012 and who participated in a pre-surgery study was conducted. Data on pre-surgery demographics, anthropometrics, and medical status were obtained from the patients' medical records. Data on long-term health status, anthropometrics, lifestyle and eating habits, eating pathologies, follow-up regime, and satisfaction from the surgery were collected by an interview phone calls according to a structured questionnaire. RESULTS: Data of 169 patients were available before and 7.8±1.0 years post-SG. Their baseline mean age was 41.8±11.3 years, and 71.6% of them were females. The mean post-surgery excess weight loss (EWL) was 53.2±31.2%, and 54.2% had EWL of ≥50%. Eating 3-6 meals per day, not having the urge to eat after dinner, separating liquids from solids, avoiding carbonated beverages, and performing physical activity were related to better weight-loss outcomes (P≤0.026). However, frequent need for eating sweets, binge eating, and feeling guilty or sad after eating were related to worse weight-loss outcomes (P≤0.010). Furthermore, only a minority reported taking a multivitamin and participating in follow-up meetings after more than 1 year since the surgery (≤21.3%). CONCLUSIONS: In the long term following SG, approximately half achieved EWL of ≥50%, and physical activity, certain eating patterns, and eating pathologies were related to weight outcomes.

OBJECTIVE: To investigate the extent, quality and challenges of dietetic counselling during the pandemic. DESIGN: A cross-sectional online thirty-six-item Google Survey. The survey queried demographics and information on usage and perceived telemedicine quality. SETTING: The survey was distributed to Israeli Dietetic Association (ATID) mailing list between 31 March and 5 May 2020. PARTICIPANTS: Clinical dietitians, members of ATID, who consented to participated in the survey. RESULTS: Three hundred dietitians (12 % of ATID members; 95 % women; mean age 4·41 (sd 10·2) years) replied to the survey. Most dietitians reported a significant â¼30 % decrease in work hours due to the pandemic. The most prevalent form of alternative nutrition counselling (ANC) was over the phone (72 %); 53·5 % used online platforms. Nearly 45 % had no former ANC experience. Both ANC formats were reported inferior to face-to-face nutritional consultation (consultation quality median scores 8 and 7, on a 1-10 scale, for online and phone, respectively). ANC difficulties on either phone or online platforms were technical (56 and 47 %, respectively), lack of anthropometric measurements (28 and 25 %, respectively) and interpersonal communication (19 and 14·6 %, respectively). Older age and former phone counselling experience were associated with higher quality scores, respectively (OR = 1·046, 95 % CI 1·01, 1·08, P = 0·005), (95 % CI 1·38, 4·52, P = 0·02). Those who continued to work full time had five-time greater odds for a higher quality score using online platforms (OR = 5·33, 95 % CI 1·091, 14·89, P = 0·001). CONCLUSIONS: Our findings suggest telemedicine holds considerable promise for dietary consultation; however, additional tools and training are needed to optimise remote ANC, especially in light of potential crisis-induced lockdown.

One anastomosis gastric bypass/Mini Gastric Bypass (OAGB/MGB) is an emerging bariatric surgery (BS) technique. We evaluated and compared attitudes of bariatric surgeons and dietitians towards the considerations for choosing BS-type ("Decision-making"), the contributing factors to the rise of OAGB/MGB in Israel ("OAGB/MGB-rise") and notions regarding the occurrence of gastrointestinal (GI) symptoms and nutritional deficiencies following OAGB/MGB. Anonymous online surveys were distributed. The participants were asked to rate by a 10-point Likert scale (0 = not at all; 100 = very much/often) their attitudes towards "Decision-making", "OAGB/MGB-rise" and occurrence of GI symptoms and nutritional deficiencies following OAGB/MGB. For "Decision-making" and "OAGB/MGB-rise", items were considered prioritized where ≥ 50% of the group considered them as 'very-important' (rating ≥ 80). Data on age, sex, years-in-practice and main workplace were also collected. A total of 106 professionals participated in the survey (42 surgeons; 64 dietitians). The respective mean age, years-in-practice and sex were 52.3 ± 8.7 vs. 42.3 ± 9.0 years, 21.0 ± 10.8 vs. 15.5 ± 9.2 years and 85.7% vs. 3.1% males. The inter-observer agreement for prioritized items related to "Decision-making" was fair (Kappa = 0.250; P = 0.257) and both groups prioritized patient's BMI, comorbidities and compliance. The inter-observer agreement for prioritized items related to "OAGB/MGB-rise" was moderate (Kappa = 0.550; P = 0.099) and both groups prioritized ease of performance, shorter operation duration and failure of former restrictive BS. Surgeons reported lower occurrence of nutritional deficiencies and GI symptoms as adverse effects of OAGB/MGB (P ≤ 0.033). The study highlights the views of bariatric surgeons and dietitians concerning factors that underpin the rise of OABG/MGB in Israel and possible rates of GI symptoms and nutritional deficiencies associated with this modality.

Bariatric surgery (BS) has proven to be highly efficacious in the treatment of obesity and its comorbidities. However, careful patient selection is critical for its success. Thus, patients should undergo medical, behavioral, and nutritional assessment by a multidisciplinary team. From the nutritional point of view, BS candidates should undergo nutritional assessment, preparation, and education by a registered dietitian in the preoperative period. Currently, detailed specified and comprehensive information on these topics is lacking. The present narrative review aimed to summarize the available literature concerning both the preoperative nutritional assessment components and the preoperative nutritional preparation and education components of patients planning to undergo BS. Current literature indicates that proper management before BS should include a comprehensive nutritional assessment, in which it is advisable to perform a clinical interview to assess patients' medical background, weight management history, eating patterns and pathologies, oral health, physical activity habits, nutritional status, supplementation usage, BS knowledge, surgery expectations and anthropometric measurements. Nutritional preparation and educational strategies should include an individualized preoperative weight-loss nutrition program, improvement of glycemic control, micronutrients deficiencies correction, eating and lifestyle habits adaptation, physical activity initiation, and strengthening knowledge on obesity and BS. At this stage, more well-designed intervention and long-term cohort studies are needed in order to formulate uniform evidence-based nutritional guidelines for patients who plan to undergo BS, including populations at higher nutritional risk. Moreover, postoperative outcomes of presurgical nutritional intervention programs should be studied.

Vitamin E, a fat-soluble vitamin with antioxidant properties, is thought to modulate enzymes involved in signal transduction, affect gene expression, and have immunomodulatory capabilities. Severe vitamin E deficiency is associated with neuronal disorders, impaired immune response, hemolytic anemia, and oxidative-based disorders. Patients who undergo bariatric surgery (BS), especially malabsorptive procedures, are at greater risk of developing fat-soluble vitamin deficiencies. Current data on vitamin E statuses among BS patients are limited. Therefore, this systematic review has summarized the scientific literature on vitamin E and examined its status among patients following different types of BS. Searches of the MEDLINE and Embase databases were performed, followed by hand-searching of reference lists from all relevant papers. Of the 671 initially identified articles, 24 met the inclusion criteria: 1 study on adjustable gastric banding patients (n = 21), 4 studies on sleeve gastrectomy patients (n = 173), 12 studies on Roux-en-Y gastric bypass patients (n = 689) and 12 studies on biliopancreatic diversion with or without duodenal switch (n = 799) or single anastomosis duodeno-ileal bypass with sleeve gastrectomy patients (n = 163). Results suggest that patients who undergo malabsorptive procedures are at higher risk of developing vitamin E deficiency, although clinical manifestations of vitamin E deficits following BS are rarely documented. The optimal dose of vitamin E supplementation required for prevention of deficiency or for treatment following BS has yet to be established. Future observational and intervention studies are needed to bridge the gaps in existing knowledge.

BACKGROUND: Food addiction and binge eating are common among individuals with obesity. However, a paucity of studies prospectively examined the prevalence and implications of food addiction before and post-bariatric surgery. We aimed to examine the prevalence of food addiction and binge eating before and after sleeve gastrectomy (SG) and to assess their associations with behavioral and weight loss outcomes. METHODS: We followed at 3 (M3), 6 (M6), and 12 (M12) months postoperative, 54 women who underwent SG. Data collected including anthropometrics, nutritional intake, food tolerance, and physical activity measures. The Yale Food Addiction Scale and the Binge Eating Scale were used to characterize food addiction and binge eating, respectively. RESULTS: The mean baseline age and BMI were 32.1 ± 11.1 years and 44.9 ± 4.9 kg/m2, respectively. Pre-surgery, food addiction, and binge eating were identified in 40.7% and 48.1% of patients, respectively. The prevalence of food addiction decreased significantly up to M6, but increased to 29.3% at M12. The prevalence of binge eating decreased significantly through the follow-up up to 17.4% at M12. Those who met criteria for food addiction at M12 achieved significantly lower excess weight loss at M12 compared with those not meeting this criterion (P = 0.005). Food addiction scores at M12 negatively correlated with weekly physical activity (r = - 0.559; P < 0.001) and food tolerance scores (r = - 0.428; P = 0.005). CONCLUSIONS: The reduction in food addiction observed at M6 was not maintained at M12. Food addiction at M12 was associated with poorer weight loss, eating, and lifestyle behaviors. Clinical practice should focus on the psychological aspects associated with obesity.
