The grade of obesity affects the noninvasive diagnosis of advanced fibrosis in individuals with MASLD.

OBJECTIVE: Metabolic dysfunction-associated steatotic liver disease (MASLD) is closely associated with obesity. We aimed to assess the impact of obesity on the performance of different noninvasive tests, including liver stiffness measurement (LSM) and Agile3+ (A3+), to detect advanced fibrosis (AF) in a population of patients with MASLD encompassing a wide range of BMI values. METHODS: A total of 479 patients with MASLD were consecutively included (Lyon Hepatology Institute). Clinical data and noninvasive tests, including FibroTest, LSM, A3+, Fibrosis-4 (FIB-4), magnetic resonance elastography, and liver biopsies, were collected. AF was determined by a composite endpoint, i.e., histological stage ≥ F3, overt diagnosis of cirrhosis by magnetic resonance elastography, or concordant LSM ≥ 9.6 kPa and FibroTest ≥ F3. RESULTS: The median BMI was 35.0 kg/m2, and the prevalence of AF was 28.6%. Patients with BMI ≥ 35 versus <35 had a lower proportion of AF, i.e., 19.3% versus 38.1% (p < 0.001), but higher indeterminate status for AF (34.2% vs. 15.4%; p < 0.001). In the case of BMI ≥ 35, LSM had lower specificity to rule in AF (77.9%) versus A3+ (90.4%), but A3+ had decreased sensitivity to rule out AF. A sequential LSM/A3+ strategy achieved high specificity to rule in AF and lowered the proportion of indeterminate cases in patients with BMI ≥ 35. CONCLUSIONS: The grade of obesity affects the detection of MASLD-related AF. A sequential use of LSM/A3+ could improve AF detection in patients with BMI ≥ 35.

Efficacy and safety of one anastomosis gastric bypass versus Roux-en-Y gastric bypass at 5 years (YOMEGA): a prospective, open-label, non-inferiority, randomised extension study.

BACKGROUND: The multicentre randomised trial YOMEGA (NCT02139813) comparing the one anastomosis gastric bypass (OAGB) with the Roux-en-Y gastric bypass (RYGB) confirmed the non-inferiority of OAGB on weight loss outcomes at 24 months. We aimed to report weight loss, metabolic, and safety outcomes at 5 years. METHODS: YOMEGA is a prospective, open-label, non-inferiority, randomised trial conducted at nine centres in France. Inclusion criteria were BMI of 40 kg/m2 or more, or 35 kg/m2 or more with comorbidities. Key exclusion criteria were severe gastro-oesophageal reflux disease or Barrett's oesophagus and previous bariatric surgery. Patients were randomly assigned (1 :1) to OAGB (one gastrojejunal anastomosis with a 200 cm biliopancreatic limb) or RYGB (with a 150 cm alimentary limb and a 50 cm biliary limb), stratified by centre, with blocks of variable size. The primary endpoint of this extension study was percentage excess BMI loss and was analysed in the per-protocol population, including patients with data who were operated on with the technique randomly assigned to them and excluding patients with major deviations from the protocol during the follow-up (change of surgical technique, death, or withdrawal of consent). Non-inferiority was concluded for the primary endpoint if the upper bound of the CI was less than the non-inferiority limit (7 percentage points). YOMEGA is registered with ClinicalTrials.gov, NCT02139813, and the 5-year follow-up of YOMEGA is registered with ClinicalTrials.gov, NCT05549271. FINDINGS: Between May 13, 2014, and March 2, 2016, 253 patients were randomly assigned to OAGB (n=129) or RYGB (n=124), and from these patients 114 in the OAGB group and 118 in the RYGB group were included in the per-protocol analysis. In the per-protocol population, at baseline, mean age was 43·0 years (SD 10·8), mean BMI was 44·0 kg/m2 (5·6), 54 (23%) patients were male and 178 (77%) were female; 55 (27%) of 207 patients had type 2 diabetes. After 5 years, mean percentage excess BMI loss was -75·6% (SD 28·1) in the OAGB group versus -71·4% (SD 29·8) in the RYGB group, confirming non-inferiority (mean difference -4·1% [90% CI -12·0 to 3·7], p=0·0099). Remission of type 2 diabetes was similar in both groups. Nutritional status did not differ; the most common adverse event was clinical gastro-oesophageal reflux disease, occurring in 27 (41%) of 66 patients in the OAGB group versus 14 (18%) of 76 patients in the RYGB group (p=0·0030). Among serious adverse events, ten (8%) of 127 patients converted from OAGB to RYGB. 171 (68%) of 253 patients were followed up. INTERPRETATION: OAGB was not inferior to RYGB regarding percentage excess BMI loss at 5 years with similar metabolic outcomes. The high rate of clinical gastro-oesophageal reflux disease after OAGB raises questions about its long-term consequences, which need to be further investigated. FUNDING: Medtronic.

Dual alcohol and metabolic-related liver disease: Results from a population of liver transplant patients.

BACKGROUND & AIMS: If alcohol-related liver disease (ALD) and nonalcoholic fatty liver disease (NAFLD) are now the two main indications for liver transplantation (LT), it has been recognized that both conditions can coexist in varying degrees and the concept of dual-aetiology fatty liver disease (DAFLD) has been proposed. This retrospective study aimed to evaluate, in a cohort of patients transplanted for ALD and NAFLD, the prevalence of DAFLD before LT and the impact on liver graft outcome. METHODS: From 1990 to 2010, all patients who underwent LT for the so-called ALD or NAFLD in our centre were included. Before LT, DAFLD was defined as patients with a history of excessive alcohol consumption and obesity associated with either diabetes or hypertension. Before LT, patients were separated into three groups: DAFLD, ALD, and NAFLD. Fatty liver graft disease was classified according to the FLIP algorithm. RESULTS: Out of 907, adult LT recipients were identified: 33 DAFLD patients, 333 ALD patients, and 24 NAFLD patients. After LT, ALD patients experienced significantly more alcohol relapse than DAFLD patients, who had twice more post-LT metabolic syndrome. Out of 926, post-LT biopsies, DAFLD patients had significantly more fatty liver graft disease due to metabolic syndrome features than ALD patients. CONCLUSION: Our results support that DAFLD recently emerged as an indication of LT. In the future, this particular population needs to be identified as a specific entity since post-LT outcome on the graft is different from ALD and more similar to NAFLD patients.

Out-of-Pocket Expenses in Households of People Living with Obesity in France.

BACKGROUND/OBJECTIVES: Overweight and obesity result in a substantial economic burden in both low- and high-income countries. Moreover, this burden is often underestimated because it only partially accounts for unreimbursed out-of-pocket expenses (OOPE) related to obesity. The objective of our study was not only to evaluate OOPE incurred by people with obesity in relation to their disease with respect to direct medical expenditures and direct non-medical expenditures but also the proportion of people living with obesity who have forgone obesity-related healthcare due to the costs of such care. METHODS: An observational descriptive survey was conducted among people with class II/III obesity attending six obesity treatment centers in France. Volunteer adult participants completed a written/phone questionnaire on their related expenditures over the last 6 months for current expenditures and over the last 5 years for occasional ones. The costs were expressed in 2022 EUR. RESULTS: 299 people participated (age: 46 years [SD: 13.9], women: 72%, BMI ≥40 kg/m2: 62% and 48% with comorbidities). 65% had a professional activity. 83% declared that they had OOPE related to obesity representing annually EUR 2027/individual on average (5% of the household revenue), including weight loss and nutritional products, vitamins, meal programs, gym memberships, psychologists, but mainly adapted clothing, additional travel costs, and others. 15% of the respondents had to modify their professional activity due to obesity and 15% forwent some medical care in the last 12 months. CONCLUSIONS: OOPE is a significant part of the economic burden of obesity. Despite some limitations due to the specificities of the participants and because some costs may be more related to social activities affected by obesity than to healthcare, it seems important to consider these expenditures in cost estimates for obesity.

Comparison of Pathway Referrals for Liver Fibrosis Risk Stratification Performed in Diabetology and Nutrition Clinics.

Purpose: A systematic screening for the presence of nonalcoholic fatty liver disease (NAFLD)-related advanced fibrosis is currently recommended in patients with type 2 diabetes mellitus (T2DM) and obesity. However, real-world data of such liver fibrosis risk stratification pathway from diabetology and nutrition clinics towards hepatology clinics are scarce. Therefore, we compared data from two pathways with or without transient elastography (TE) performed in diabetology and nutrition clinics. Patients and Methods: This is a retrospective study comparing the proportion of patients with intermediate/high risk of advanced fibrosis (AF) as defined by a liver stiffness measurement (LSM) ≥8kPa, among patients referred in hepatology from two diabetology-nutrition departments at Lyon University Hospital, France between November 1st 2018 to December 31st 2019. Results: Among the two diabetology and nutrition departments using TE or not, 27.5% (62/225) versus 44.2% (126/285) were referred to hepatology, respectively. The pathway using TE in diabetology and nutrition referred to hepatology a higher proportion of patients with intermediate/high risk of AF compared to the pathway without TE: 77.4% versus 30.9%, p<0.001. In the pathway with TE, the odds of patients with intermediate/high risk of AF referred to hepatology was significantly higher: OR: 7.7, 95% CI: 3.6-16.7, p<0.001 after adjustment for age, sex and presence of obesity and T2D compared to the pathway without TE in diabetology and nutrition clinics. However, among the patients not referred, 29.4% had an intermediate/high risk of AF. Conclusion: A pathway-referral using TE performed in diabetology and nutrition clinics, significantly improves the liver fibrosis risk stratification and avoids over-referral. However, collaboration between diabetologist, nutritionists and hepatologists is needed to avoid under-referral.

Autoantibodies to Perilipin-1 Define a Subset of Acquired Generalized Lipodystrophy.

Acquired lipodystrophy is often characterized as an idiopathic subtype of lipodystrophy. Despite suspicion of an immune-mediated pathology, biomarkers such as autoantibodies are generally lacking. Here, we used an unbiased proteome-wide screening approach to identify autoantibodies to the adipocyte-specific lipid droplet protein perilipin 1 (PLIN1) in a murine model of autoimmune polyendocrine syndrome type 1 (APS1). We then tested for PLIN1 autoantibodies in human subjects with acquired lipodystrophy with two independent severe breaks in immune tolerance (including APS1) along with control subjects using a specific radioligand binding assay and indirect immunofluorescence on fat tissue. We identified autoantibodies to PLIN1 in these two cases, including the first reported case of APS1 with acquired lipodystrophy and a second patient who acquired lipodystrophy as an immune-related adverse event following cancer immunotherapy. Lastly, we also found PLIN1 autoantibodies to be specifically enriched in a subset of patients with acquired generalized lipodystrophy (17 of 46 [37%]), particularly those with panniculitis and other features of autoimmunity. These data lend additional support to new literature that suggests that PLIN1 autoantibodies represent a marker of acquired autoimmune lipodystrophies and further link them to a break in immune tolerance.

Initiation of the Fixed Combination IDegLira in Patients with Type 2 Diabetes on Prior Injectable Therapy: Insights from the EASY French Real-World Study.

INTRODUCTION: Combining basal insulin (BI) with glucagon-like peptide-1 receptor agonist (GLP-1RA) is recognized as a relevant option to optimize glucose control in type 2 diabetes (T2D). The EASY real-world study aimed to evaluate the modalities of initiation and the effectiveness of the insulin Degludec plus Liraglutide (IDegLira) fixed-ratio combination in the French health care system. METHODS: A retrospective analysis included all patients with T2D and prior injectable therapy (GLP1-RA and/or insulin) who started treatment with IDegLira from September 2016 to December 2017 in 11 French diabetes centers. Baseline characteristics, reasons for IDegLira initiation, and modes of implementation were collected from the medical records. Changes in HbA1c and body weight were determined in patients with available follow-up data (nearest 6-month visit). RESULTS: IDegLira was initiated in 629 patients previously treated with GLP-1RA alone (11.6%), insulin alone (31.5% including 16.5% with BI and 14.9% with multiple daily injections [MDI]) or a free combination of GLP-1RA and insulin (56.9% including 44.8% with BI and 12.1% with MDI), associated or not with oral agents. IDegLira starting dose (mean of 29 ± 11 dose steps) most often exceeded the recommended dose, and was significantly correlated with prior BI but not GLP-1RA dosage. At initiation, mean age, body mass index (BMI) and HbA1c were 60.1 ± 10.2 years, 33.4 ± 6.2 kg/m2 and 8.8 ± 1.7%, respectively. In 461 patients with available follow-up (median 178 days), HbA1c decreased in all subgroups submitted to treatment intensification (- 1.7 ± 1.8% [p < 0.0001], - 1.2 ± 1.8% [p < 0.001] and - 0.8 ± 1.8% [p = 0.0026] in patients with prior GLP-1RA, BI or MDI therapy, respectively) but also in those switching from BI and GLP-1RA free combination (- 0.2 ± 0.9%, p = 0.0419). Significant body weight gain occurred in patients previously treated with GLP-1RA alone (+ 1.5 ± 5.8 kg, p = 0.0572) or combined to BI (+ 1.0 ± 3.1 kg, p < 0.0001) while those on BI (- 1.4 ± 4.6 kg, p = 0.0139) or MDI (- 1.4 ± 5.0 kg, p = 0.0484) experienced weight loss. CONCLUSIONS: While providing new information on the use of IDegLira in the French healthcare system, these data confirm the effectiveness of this fixed-ratio combination in the management of T2D.

Polyphenol Supplementation Did Not Affect Insulin Sensitivity and Fat Deposition During One-Month Overfeeding in Randomized Placebo-Controlled Trials in Men and in Women.

Two randomized placebo-controlled double-blind paralleled trials (42 men in Lyon, 19 women in Lausanne) were designed to test 2 g/day of a grape polyphenol extract during 31 days of high calorie-high fructose overfeeding. Hyperinsulinemic-euglycemic clamps and test meals with [1,1,1-13C3]-triolein were performed before and at the end of the intervention. Changes in body composition were assessed by dual-energy X-ray absorptiometry (DEXA). Fat volumes of the abdominal region and liver fat content were determined in men only, using 3D-magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) at 3T. Adipocyte's size was measured in subcutaneous fat biopsies. Bodyweight and fat mass increased during overfeeding, in men and in women. While whole body insulin sensitivity did not change, homeostasis model assessment of insulin resistance (HOMA-IR) and the hepatic insulin resistance index (HIR) increased during overfeeding. Liver fat increased in men. However, grape polyphenol supplementation did not modify the metabolic and anthropometric parameters or counteract the changes during overfeeding, neither in men nor in women. Polyphenol intake was associated with a reduction in adipocyte size in women femoral fat. Grape polyphenol supplementation did not counteract the moderated metabolic alterations induced by one month of high calorie-high fructose overfeeding in men and women. The clinical trials are registered under the numbers NCT02145780 and NCT02225457 at ClinicalTrials.gov and available at https://clinicaltrials.gov/ct2/show/NCT02145780 and https://clinicaltrials.gov/ct2/show/NCT02225457.

Food Reward after Bariatric Surgery and Weight Loss Outcomes: An Exploratory Study.

Changes in food preferences after bariatric surgery may alter its effectiveness as a treatment for obesity. We aimed to compare food reward for a comprehensive variety of food categories between patients who received a sleeve gastrectomy (SG) or a Roux-en-Y gastric bypass (RYGB) and to explore whether food reward differs according to weight loss. In this cross-sectional exploratory study, food reward was assessed using the Leeds Food Preference Questionnaire (LFPQ) in patients at 6, 12, or 24 months after SG or RYGB. We assessed the liking and wanting of 11 food categories. Comparisons were done regarding the type of surgery and total weight loss (TWL; based on tertile distribution). Fifty-six patients (30 SG and 26 RYGB) were included (women: 70%; age: 44.0 (11.1) y). Regarding the type of surgery, scores were not significantly different between SG and RYGB, except for 'non-dairy products-without color' explicit liking (p = 0.04). Regarding TWL outcomes, explicit liking, explicit wanting, and implicit wanting, scores were significantly higher for good responders than low responders for 'No meat-High fat' (post-hoc corrected p-value: 0.04, 0.03, and 0.04, respectively). Together, our results failed to identify major differences in liking and wanting between the types of surgery and tended to indicate that higher weight loss might be related to a higher reward for high protein-content food. Rather focus only on palatable foods, future studies should also consider a broader range of food items, including protein reward.

[Psychiatric disorders and bariatric surgery]. / Troubles psychiatriques et chirurgie bariatrique.

PSYCHIATRIC DISORDERS AND BARIATRIC SURGERY Psychiatric disorders are common in people with obesity and their lifetime prevalence is estimated to range from 30 % to 70 %. The most frequently reported disorders are mood and anxiety disorders, attention deficit disorder, and binge eating disorder. These disorders will usually improve after bariatric surgery and do not appear to have a significant negative impact on weight loss. However, increased attention is needed regarding some aspects of these disorders (e. G., emotional dysregulation, impulsivity) as well as regarding the increased risk of developing a substance abuse disorder or increased suicide risk after bariatric surgery. As well as a high quality pre-operative psychiatric assessment is required, post-operative psychiatric follow-up is required.

TROUBLES PSYCHIATRIQUES ET CHIRURGIE BARIATRIQUE Les troubles psychiatriques sont fréquents en cas d'obésité, et leur prévalence est estimée entre 30 et 70 %. Les plus fréquents sont les troubles de l'humeur, les troubles anxieux, le trouble du déficit de l'attention, et l'hyperphagie boulimique. La plupart d'entre eux s'améliorent après une chirurgie bariatrique et ne semblent pas affecter de façon importante le pronostic pondéral. Cependant, un regain de vigilance s'impose quant à certaines composantes de ces troubles (par exemple la dysrégulation émotionnelle, l'impulsivité) et devant une augmentation des risques de développer une addiction et de suicide après une chirurgie bariatrique. Au-delà de la nécessité d'une évaluation psychiatrique préopératoire de qualité, un suivi psychiatrique postopératoire apparaît de plus en plus nécessaire, ne serait-ce que pour identifier les risques émergents.

Adipose-Tissue-Derived Mesenchymal Stem Cells Mediate PD-L1 Overexpression in the White Adipose Tissue of Obese Individuals, Resulting in T Cell Dysfunction.

The PD-L1/PD-1 immune checkpoint axis is the strongest T cell exhaustion inducer. As immune dysfunction occurs during obesity, we analyzed the impact of obesity on PD-L1/PD-1 expression in white adipose tissue (WAT) in mice and in human white adipocytes. We found that PD-L1 was overexpressed in WAT of diet-induced obese mice and was associated with increased expression of PD-1 in visceral but not subcutaneous WAT. Human in vitro cocultures with adipose-tissue-derived mesenchymal stem cells (ASC) and mononuclear cells demonstrated that the presence of ASC harvested from obese WAT (i) enhanced PD-L1 expression as compared with ASC from lean WAT, (ii) decreased Th1 cell cytokine secretion, and (iii) resulted in decreased cytolytic activity towards adipocytes. Moreover, (iv) the implication of PD-L1 in obese ASC-mediated T cell dysfunction was demonstrated through PD-L1 blockade. Finally, (v) conditioned media gathered from these cocultures enhanced PD-L1 expression in freshly differentiated adipocytes, depending on IFNγ. Altogether, our results suggest that PD-L1 is overexpressed in the WAT of obese individuals during IFNγ secretion, leading to T cell dysfunction and notably reduced cytolytic activity. Such a mechanism could shed light on why adipose-tissue-infiltrating viruses, such as SARS-CoV-2, can worsen disease in obese individuals.

A systematic review and meta-analyses of food preference modifications after bariatric surgery.

This systematic review and meta-analyses aimed to synthesize evidence of the link between bariatric surgery and changes in food preferences, considering the method of assessment. MEDLINE, Cochrane Library, Web of Science, Cinahl, PsychINFO, ProQuest, and Open grey were searched incorporating two blocks of terms ("Intervention" and "Food Preferences"). Interventional or observational studies involving patients (BMI ≥ 35 kg m-2 ) with sleeve gastrectomy (SG) or Roux-en-Y Gastric Bypass (RYGB) and a control group were included. Meta-analyses were performed comparing the standardized daily mean percentage energy from proteins, carbohydrates, and lipids between preoperative and postoperative patients. Fifty-seven studies concerning 2,271 patients with RYGB and 903 patients with SG met the inclusion criteria, of which 24 were eligible for meta-analysis. Despite a total reduction in macronutrient intakes, the meta-analyses revealed a postoperative increase in percentage energy from proteins at 12 months (0.24, 95% CI: 0.03, 0.46, {I2 } = 73%) and a decrease in percentage energy from fat at 1 month (-0.47, 95% CI: 0.86, 0.09, {I2 } = 72%), up to 24 months (-0.20, 95% CI: -0.31, 0.08, {I2 } = 0%). In conclusion, the present systematic review and meta-analyses showed changes of food preferences in terms of macronutrient, food selection and, overall food appreciation up to 5 years following bariatric surgery.

Graves' Disease during Immune Checkpoint Inhibitor Therapy (A Case Series and Literature Review).

Thyrotoxicosis is an adverse event associated with immune checkpoint inhibitors (ICPis) that occurs in 0.6 to 3.2% of treated patients, depending on ICPi class. Presentation usually consists of a biphasic thyroiditis with transient thyrotoxicosis and secondary hypothyroidism. ICPi-induced Graves' disease (GD), due to the stimulating activity of TSH-receptor autoantibodies (TRAb), is extremely rare. The aim of this retrospective study was to describe the characteristics and evolution of GD during ICPi therapy. Five among 243 patients followed for ICPi-induced thyrotoxicosis showed TRAb positivity (2% of the cohort). GD occurred quickly after initiation of ICPis; its course was typical for two patients, with prolonged requirement for antithyroid drug treatment (ATD). The three other patients experienced biphasic thyroiditis with secondary hypothyroidism requiring long-term substitution. Three other patients had a diagnosis of GD before starting ICPis; they evolved toward hypothyroidism with early cessation of ATD and long-term substitution treatment during ICPi treatment. None developed significant Graves' orbitopathy. ICPi treatment was not interrupted for thyroid dysfunction. In conclusion, GD is a rare, immune-related adverse event of ICPis with an unusual course and frequent evolution to biphasic thyroiditis. In the case of ICPi-induced thyrotoxicosis in the presence of TRAb, observing the spontaneous evolution and performing a scintigraphy are useful before starting ATD treatment. Pre-existing GD is not exacerbated by ICPis and tends to evolve towards hypothyroidism. ICPi treatment can be maintained with adequate biochemical surveillance.

Food Preferences and Their Perceived Changes Before and After Bariatric Surgery: a Cross-sectional Study.

PURPOSE: Changes in food preferences, taste, and smell following bariatric surgery have been previously described but with inconsistent results. We aimed to describe current food preferences and their perceived changes before and after the surgery. We further compared food preferences between patients with and without taste or smell alterations, before and above 2 years follow-up, and concerning the success or failure of their surgery. MATERIALS AND METHODS: This cross-sectional study was conducted with a self-administered online questionnaire. Two years was the cut-off between short- and long-term follow-up. Success was defined as an excess weight loss (EWL) greater or equal to 50%. RESULTS: In total, 220 postoperative patients answered the questionnaire. Patients with taste alterations (64%) had significantly lower preferences for red meat, milk, cheese, desserts, fried foods, and water (all p < 0.05) relative to the non-taste alteration group, while those with smell alterations (38%) had significantly lower preference for cheese only (p < 0.05) relative to the non-smell alteration group. Patients with a ≥ 2-year follow-up had a higher liking for desserts, fried foods, fat, bread, hot drinks, and alcohol compared to patients with a < 2-year follow-up (all p < 0.05). Patients having success in surgery had higher liking scores for green vegetables and lower liking scores for starchy foods, milk, and sweet dairy products (all p < 0.05). CONCLUSIONS: Our study suggests that patients who underwent bariatric surgery have different food preference patterns according to their sensory perceptions, the duration of their follow-up, and the success of bariatric surgery.

Revision of Mason's procedure (vertical banded gastroplasty) to Roux-en-Y gastric bypass: role of an associated fundectomy in weight loss outcomes.

BACKGROUND: Vertical banded gastroplasty (VBG) presents a significant rate of long-term complications, and revisions are often necessary. Conversion to Roux-en-Y gastric bypass (RYGB) seems to be preferred, but literature data remain limited. OBJECTIVES: To analyze the indications, safety, results of conversions from VBG to RYGB, and to identify predictive factors of success or failure. SETTING: Two specialized centers of bariatric surgery. METHODS: This bicentric retrospective study included all the patients who benefited from a conversion from VBG to RYGB between 2008 and January 2020. Demographic characteristics, indications, preoperative workups, intraoperative data, complications, and weight loss results were analyzed. RESULTS: During the study period, 85 patients underwent a conversion to RYGB. The mean body mass index (BMI_ before conversion was 40.6 kg/m2. 82.3% of the patients were converted because of weight loss failure and 17.6% because of a complication of their VBG. The global rate of complications was 25%. After an average follow-up of 35 months and a rate of loss to follow-up of 33%, the mean BMI was 33.5 kg/m. The weight loss success rate according to Reinhold's criteria was 64.7%, and resolution of complications was obtained in 89.1%. The association of a fundectomy was a predictive factor of weight loss (odds ratio, .27; P = .04), whereas primary failure of the VBG was a predictive factor of failure. CONCLUSION: Conversion from VBG to RYGB remains the procedure of choice to achieve satisfying weight loss and resolution of functional complications. The addition of a fundectomy appeared to have a significant positive impact on weight loss outcomes.

An artificial intelligence-derived tool proposal to ease disordered eating screening in people with obesity.

PURPOSE: In people with obesity, food addiction (FA) tends to be associated with poorer outcomes. Its diagnosis can be challenging in primary care. Based on the SCOFF example, we aim to determine whether a quicker and simpler screening tool for FA in people with obesity could be developed, using artificial intelligence (machine learning). METHODS: The first step was to look for the most discriminating items, among 152 different ones, to differentiate between FA-positive and FA-negative populations of patients with obesity. Items were ranked using the Fast Correlation-Based Filter (FCBF). Retained items were used to test the performance of nine different predictive algorithms. Then, the construction of a graphic tool was proposed. RESULTS: Data were available for 176 patients. Only three items had a FCBF score > 0.1: "I eat to forget my problems"; "I eat more when I'm alone"; and "I eat sweets or comfort foods". Naive Bayes classification obtained best predictive performance. Then, we created a 3-item nomogram to predict a positive scoring on the YFAS. CONCLUSION: A simple and fast screening tool for detecting high-disordered eating risk is proposed. The next step will be a validation study of the FAST nomogram to ensure its relevance for emotional eating diagnosis. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Third bariatric procedure for insufficient weight loss or weight regain: how far should we go?

BACKGROUND: Revisional procedures in bariatric surgery are increasing with several debated failure risk factors, such as super obesity and old age. No study has yet evaluated the outcomes and risks of a third bariatric procedure indicated for weight loss failure or weight regain. OBJECTIVES: To assess failure risks of a third bariatric procedure according to Reinhold's criteria (percentage excess weight loss [%EWL] ≤50% and/or body mass index [BMI] ≥35 kg/m2). SETTING: A university-affiliated tertiary care center, France. METHODS: From 2009 to 2019, clinical data and weight loss results of patients who benefited from 3 bariatric procedures for weight loss failure or weight regain were collected prospectively and analyzed using a binary logistic regression. Weight loss failure was defined according to Reinhold's criteria. RESULTS: Among 1401 bariatric procedures performed, 336 patients benefited from 2 or more procedures, and 45 had a third surgery. Eleven patients that were reoperated on because of malnutrition or gastroesophageal reflux disease were excluded from the final analysis. Among 34 patients with 3 procedures because of weight loss failure or regain, mean BMI was 48.3 ± 8.3 kg/m2, and mean age was 30 ± 10.7 years. Three out of 34 patients (9%) presented a severe complication (Dindo-Clavien IIIb) and 2 (6%) had a minor one. Achieving Reinhold's weight loss criteria after the second bariatric procedure was a significant predictor of success of the third procedure (ß = 2.9 ± 1.3 S.E.). CONCLUSION: Not reaching Reinhold's criteria after a second bariatric procedure was identified as a significant risk factor of failure of a third procedure. A third surgery should be carefully discussed especially in case of primary failure of previous procedures.

Starch digestibility modulation significantly improves glycemic variability in type 2 diabetic subjects: A pilot study.

BACKGROUND AND AIMS: In type 2 diabetes (T2D) patients, the reduction of glycemic variability and postprandial glucose excursions is essential to limit diabetes complications, beyond HbA1c level. This study aimed at determining whether increasing the content of Slowly Digestible Starch (SDS) in T2D patients' diet could reduce postprandial hyperglycemia and glycemic variability compared with a conventional low-SDS diet. METHODS AND RESULTS: For this randomized cross-over pilot study, 8 subjects with T2D consumed a controlled diet for one week, containing starchy products high or low in SDS. Glycemic variability parameters were evaluated using a Continuous Glucose Monitoring System. Glycemic variability was significantly lower during High-SDS diet compared to Low-SDS diet for MAGE (Mean Amplitude of Glycemic Excursions, p < 0.01), SD (Standard Deviation, p < 0.05), and CV (Coefficient of Variation, p < 0.01). The TIR (Time In Range) [140-180 mg/dL[ was significantly higher during High-SDS diet (p < 0.0001) whereas TIRs ≥180 mg/dL were significantly lower during High-SDS diet. Post-meals tAUC (total Area Under the Curve) were significantly lower during High-SDS diet. CONCLUSION: One week of High-SDS Diet in T2D patients significantly improves glycemic variability and reduces postprandial glycemic excursions. Modulation of starch digestibility in the diet could be used as a simple nutritional tool in T2D patients to improve daily glycemic control. REGISTRATION NUMBER: in clinicaltrials.gov: NCT03289494.

Anti-PD1 and Anti-PDL1-Induced Hypophysitis: A Cohort Study of 17 Patients with Longitudinal Follow-Up.

Hypophysitis, secondary to programmed cell death 1 protein (PD1) and programmed cell death 1 ligand 1 (PDL1) inhibitors, were thought to be rare, with only a few studies describing more than one case with long-term follow-up. The aim of the present study was to describe the clinical, laboratory, and morphological characteristics of PD1/PDL1 inhibitor-induced hypophysitis, and its long-term course. This cohort study was conducted at the University Hospital of Lyon, France, with longitudinal follow-up of patients. Seventeen cases of PD1/PDL1 inhibitor-induced hypophysitis were included. The median time to onset of hypophysitis was 28 weeks (range: 10-46). At diagnosis, 16 patients complained of fatigue, 12 of nausea or loss of appetite, while headache was rare. We found no imaging pituitary abnormality. All patients presented adrenocorticotropic hormone (ACTH) deficiency; other pituitary deficiencies were less common (n = 7). At last follow-up (median: 13 months), ACTH deficiency persisted in all but one patient and one patient recovered from gonadotropic deficiency. PD1/PDL1 inhibitor-induced hypophysitis is a clinical entity different from those associated to cytotoxic T-lymphocyte antigen-4 (CTLA4) inhibitors, with less obvious clinical and radiological signs, and probably a different mechanism. The paucity of symptoms demonstrates the need for systematic hormonal follow-up for patients receiving PD1/PDL1 inhibitors.

Efficacy and Safety of the Duodeno-Jejunal Bypass Liner in Patients With Metabolic Syndrome: A Multicenter Randomized Controlled Trial (ENDOMETAB).

OBJECTIVE: The aim of this study was to compare the efficacy and safety of 12-month implantation of a duodeno-jejunal bypass liner (DJBL) with conventional medical care in patients with metabolic syndrome (MS). SUMMARY BACKGROUND DATA: DJBL is an endoscopic device for treating obesity and related disorders. The persistence of favorable results after 6 months has not been tested in a controlled study. METHODS: We conducted a multicenter randomized controlled trial, stratified by center and diabetes status. The primary endpoint was the remission of MS at 12 months. The secondary endpoints included body mass index (BMI), glucose control, blood pressure, and lipids, assessed at 12 months after implantation, and again, at 12 months after the removal of the DJBL. Up to 174 subjects were planned to be randomized into either the DJBL or the control arm at a 2:1 ratio, respectively. Study enrollment was discontinued by the Scientific Monitoring Committee due to the early termination of the ENDO trial (NCT01728116) by the US Food and Drug Administration. The study was terminated after withdrawal of the device's European Conformity marking by the European Medicines Agency, and an interim analysis was performed. RESULTS: A total of 82 patients were enrolled (67.5% female, 48.8% with diabetes). At 12 months after randomization, the primary endpoint was met in 6 (12%) DJBL patients and 3 (10%) controls (P = 0.72). Patients in the DJBL group experienced greater BMI loss [mean adjusted difference (95% confidence interval, CI) -3.1 kg/m (-4.4 to -1.9) kg/m, P < 0.001] and HbA1c change [mean adjusted difference -0.5% (95% CI -0.9 to -0.2); P < 0.001] than those in the control group. No difference remained statistically significant at 12 months after the removal of the DJBL. In the DJBL group, 39% of patients experienced at least one device-related serious adverse event, which was classified as Grade III Dindo-Clavien in 22%, and required premature device explantation in 16%. CONCLUSIONS: The present study showed a transient clinical benefit of DJBL, which was only apparent at 1 year, when the device was still in situ, and was obtained at the risk of serious device-related adverse events in 39% of patients. These results do not support the routine use of DJBL for weight loss and glucose control in patients with MS.
