Abstract
Introduction Psychiatric comorbidity is frequent in bariatric surgery candidates. This study aimed to classify bariatric surgery patients according to patterns of preoperative measures of the severity of the eating disorder (ED), depression, and personality traits. Methods In the present cross-sectional study, 115 adult candidates for bariatric surgery (75 females, 65.22% of sample; mean age 37) were considered for analysis. Patients' sociodemographic and psychopathological variables were collected. K-Means clustering analysis was adopted to classify bariatric surgery candidates according to their preoperative Eating Disorder Inventory-2 (EDI-2) scores. In addition, we assessed depression and personality traits using the Beck Depression Inventory-2 (BDI-2) and the Minnesota Multiphasic Personality Inventory-2 (MMPI-2). Results Cluster analysis based on EDI-2 revealed two preoperative patterns: higher severity (n = 39), and low severity (n = 76). The more severe EDI-2 group had higher scores on the BDI-2 and presented higher scores on several MMPI-2 dimensions, particularly those related to anxiety (Psychasthenia, Anxiety, Fears, Obsessiveness), depression (Depression, including both content and clinical MMPI-2 subscales), externalizing symptoms (Anger, Cynicism, Type A Behavior), and social functioning (Social Introversion, Family Problems, Work Interference). Discussion Eating disorders symptoms in candidates for bariatric surgery are closely related to depression and different psychological conditions assessed with MMPI-2. These psychological variables should be evaluated preoperatively and targeted with more specific psychological interventions.

Monserrat Hernández M, Jiménez-Rodríguez D. Relationship of Genetic Polymorphisms and Microbial Composition with Binge Eating Disorder: A Systematic Review. Healthcare (Basel) 2024; 12:1441. [PMID: 39057584 PMCID: PMC11276772 DOI: 10.3390/healthcare12141441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2024] [Revised: 07/12/2024] [Accepted: 07/17/2024] [Indexed: 07/28/2024] Open
Abstract
Humans are the result of an evolutionary process, and because of this, many biological processes are interconnected with each other. The intestine-brain axis consists of an intricately connected neuronal-neuroendocrine circuit that regulates the sensation of hunger and satiety. Genetic variations and the consumption of unnatural diets (ultra-processed foods, high contents of sugars, etc.) can override this circuit and cause addiction to certain foods and/or the inability to feel satiety in certain situations. The patients who come to consultations (mainly psychology or nutrition) in an attempt to resolve this problem sometimes fail, which leads to them looking for new strategies based on biological predisposition. This investigation aims to evaluate the genetic studies regarding the microbiota carried out in the last 12 years in humans to try to determine which genes and microbes that have been recently studied are related to patients diagnosed with binge eating disorder or compulsive eating (presenting obesity or not). The protocol followed the PRISMA statement, and the following databases were searched from 2012 until the present day: PubMed, PsycINFO, SCOPUS, and Web of Science. Twenty-four international articles were analyzed, including cross-sectional or exploratory studies; five of them referred to the microbial composition, and in nineteen, the existence of genetic polymorphisms present in binge eating disorder or in compulsive eating could be observed: DRD2, OPRM1, COMT, MC4R, BNDF, FTO, SLC6A3, GHRL, CARTPT, MCHR2, and LRP11. Even though there is still much to investigate on the subject, it must be highlighted that, in the last 4 years, a two-fold increase has been observed in potential markers and in studies related to the matter, also highlighting the importance of different analyses in relation to psychosocial factors and their interaction with the genetic and microbial factors, for which research on the matter must be continued.

Reevaluating the Binge Eating Scale cut-off using DSM-5 criteria: analysis and replication in preoperative metabolic and bariatric surgery samples. Surg Obes Relat Dis 2023; 19:945-949. [PMID: 36959027 DOI: 10.1016/j.soard.2023.02.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 01/30/2023] [Accepted: 02/15/2023] [Indexed: 02/25/2023]
Abstract
BACKGROUND Metabolic and bariatric surgery is effective for sustained weight loss, but binge eating disorder (BED) can be associated with poorer outcomes and lead to weight regain. A common measure used to screen for BED is the Binge Eating Scale (BES). A BES cut-off score of ≥17 previously identified patients who have a high likelihood of meeting criteria for BED. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), lowered the threshold for meeting criteria for BED, and the psychometrics of the BES need to be reevaluated. OBJECTIVE The objective of the current investigation is to evaluate whether alternative cut-scores on the BES result in better classification of BED based on the DSM-5 revision of the the BED diagnostic criteria. SETTING Academic medical hospital in the Midwestern United States. METHODS Patients (n =1133) seeking metabolic and bariatric surgery were randomly split into 2 samples for validation and replication. The validation sample consisted of 561 patients (30.1% men, 35% non-White). The replication sample consisted of 572 patients who were demographically similar to the first random split sample (e.g., 25.3% men, 34.4% non-White). RESULTS Of these patients, 13.5% met DSM-5 criteria for BED in the validation sample and 13.8% met criteria for BED in the replication sample. Lowering the interpretative cut-off to ≥15 on the BES yielded sensitivity values of >.72, specificity values of >.67, and an accurate classification of BED in >.70 of patients across both samples. These classification values were as good as or better than the standard cut-off score of ≥17 in both samples. CONCLUSIONS The BES is appropriate to screen for BED in patients who are seeking bariatric surgery. A 2-point decrease in the BES score for clinical interpretation is appropriate-lowering it from 17 to 15 given DSM-5 updates to diagnostic criteria.

Abstract
Methadone maintenance treatment (MMT) remains the cornerstone for the management of opiate abuse. However, MMT can be associated with complex factors, including complications during the tolerance phase, the inability of some patients to maintain treatment effects during the tapering or abstinence phases, and the development of methadone dependence. Previous studies have revealed a sex disparity in MMT efficacy, showing that women undergoing MMT experiencing an increase in psychological symptoms compared with men and suggesting a link between disparate responses and the effects of estrogen signaling on methadone metabolism. More specifically, estradiol levels are positively associated with MMT dosing, and the expression of a single-nucleotide polymorphism (SNP) associated with estrogen receptor (ER) regulation is also associated with MMT dosing. In addition to performing mechanistic dissections of estrogen signaling in the presence of methadone, past studies have also proposed the targeting of estrogen signaling during MMT. The present report provides an overview of the relevant literature regarding sex effects, including differences in sex hormones and their potential impacts on MMT regimens. Moreover, this article provides a pharmacological perspective on the targeting of estrogen signals through the use of selective ER modulators (SERMs) during MMT. Preliminary preclinical experiments were also performed to evaluate the potential effects of targeting estrogen signaling with tamoxifen on methadone metabolism.

Abstract
BACKGROUND Eating pathologies among bariatric surgery candidates are common and associated with adverse surgical outcomes, including weight regain and low quality of life. However, their assessment is made difficult by the great variety and inconsistent use of standardized measures. OBJECTIVE The purpose of this review was to synthesize current knowledge on the prevalence of binge eating disorder (BED) in presurgical patients and to make a critical appraisal of assessment tools for BED. METHODS A search was conducted on PubMed, Scopus, and Web of Science databases from January 1994 to March 2017. Data were extracted, tabulated and summarized using a narrative approach. RESULTS A total of 21 observational studies were reviewed for data extraction and analysis. Prevalence of BED in bariatric populations ranged from 2% to 53%. Considerable variation in patient characteristics and in BED assessment measures was evident among the studies. In addition, several methodological weaknesses were recognized in most of the studies. Ten different psychometric instruments were used to assess BED. Clinical interviews were used in only 12 studies, though this is the preferred tool to diagnose BED. CONCLUSION Study heterogeneity accounted for the variability of the results from different centers and methodological flaws such as insufficient sample size and selection bias impaired the evidence on the magnitude of BED in surgical settings. For the sake of comparability and generalizability of the findings in future studies, researchers must recruit representative samples of treatment-seeking candidates for bariatric surgery and systematically apply standard instruments for the assessment of BED.

Abstract
This article describes the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and situates the instrument in contemporary psychopathology and personality literature. The historical evolution of the MMPI instruments is highlighted, including how failure to update the test for several decades resulted in increasing disinterest by basic researchers and how the restructuring efforts beginning in the 2000s promised to realign the instrument with basic research. In this regard, the construct validity associated with MMPI-2-RF scores in the context of contemporary dimensional models of psychopathology is considered. Research supporting the applied utility of the MMPI-2-RF scales in a variety of contexts-including mental health screenings, presurgical evaluations, forensic assessment, and public safety screening-is also reviewed. Critiques of the MMPI-2-RF are described and addressed. Finally, a series of recommendations for future updates of the MMPI-2-RF are described along with a path toward the MMPI-3.

Abstract
PURPOSE This study was aimed to examine the structural and construct validity of the Italian version of the Yale Food Addiction Scale in a multisite sample of postgraduate students. METHODS Two hundred and fifty-six subjects (78.1% females) aged from 18 to 53 years (mean = 23.93, SD = 4.96) and attending different postgraduate university programs at multiple Italian universities completed the Italian YFAS, the Italian Binge Eating Scale (BES), the Italian Eating Attitudes Test-26 and the Italian Dutch Eating Behavior Questionnaire (DEBQ) online through Qualtrics. RESULTS Confirmatory Factor Analysis showed that the single-factor model of the Italian YFAS including all original items had adequate fit indexes (χ2252 = 454.183; p < 0.001; normed χ2 = 1.802; RMSEA = 0.056; 90% CI 0.048-0.076; CFI = 0.761; WRMR = 1.592). However, item analysis revealed that item#25 had zero variance (all subjects were assigned the same score after item dichotomization) and item#24 had a low factor loading, and were thus removed. Furthermore, item#10 and item#11 showed to be almost perfectly correlated (r = 0.998) and were thus parceled. The resulting 19-item single-factor model revealed a better fit to the data (χ2152 = 235.69; p < 0.001; normed χ2 = 1.556; RMSEA = 0.046; 90% CI 0.034-0.058; CFI = 0.858; WRMR = 1.236) and its internal consistency was acceptable (KR-20 = 0.72). Also, a single-factor model including the seven diagnostic symptoms was tested and showed adequate fit values (χ220 = 41.911; p < 0.003; normed χ2 = 2.09; RMSEA = 0.065; 90% CI 0.037-0.093; CFI = 0.946; WRMR = 1.132). Statistically significant and small-to-high correlations were found with all convergent measures, in particular with the BES. CONCLUSION The Italian 19-item YFAS resulted to be a valid and reliable tool for the assessment of food addiction in postgraduate students. LEVEL OF EVIDENCE Level V, descriptive study.

Abstract
BACKGROUND An increase in self-harm emergencies after bariatric surgery have been documented, but understanding of the phenomenon is missing. CASE PRESENTATION The following case report describes a 26-year-old woman with obesity, who initiated self-harm behaviour after bariatric surgery. The patient reported that the self-harm was a substitute for binge eating, which was anatomically impeded after bariatric surgery.Pre-surgical psychosocial assessment revealed Anorexia Nervosa in youth, which had later migrated to Binge Eating Disorder. At the time of surgery, the patient was not fulfilling the diagnostic criteria for Binge Eating Disorder because of a low frequency of binges. The remaining binges occurred when experiencing negative affect. CONCLUSIONS Previous eating disorder pathology is an important consideration in pre-surgical assessments. For patients with affect-driven pre-surgical Binge Eating Disorder, therapeutic intervention before and after bariatric surgery could be indicated in order to secure the development of adaptive coping strategies. Furthermore, body weight as the only outcome measure for the success of surgery seems insufficient.

Neurobiological evidence for attention bias to food, emotional dysregulation, disinhibition and deficient somatosensory awareness in obesity with binge eating disorder. Physiol Behav 2017; 184:122-128.

Abstract
OBJECTIVES To refine the biobehavioral markers of binge eating disorder (BED). METHODS We conducted fMRI brain scans using images of high energy processed food (HEPF), low energy unprocessed food (LEUF), or non-foods (NF) in 42 adults (obese with BED [obese -BED; n=13] and obese with no BED [obese non-BED; n=29]) selected via ads. Two blood oxygenated level dependent (BOLD) signal contrast maps were examined: food versus nonfood, and HEPF versus LEUF. In addition, score differences on the disinhibition scale were correlated with BOLD signals. RESULTS food versus nonfood showed greater BOLD activity for BED in emotional, motivational and somatosensory brain areas: insula, anterior cingulate cortex (ACC), Brodmann areas (BA) 19 & 32, inferior parietal lobule (IPL), posterior cingulate cortex (PCC), and lingual, postcentral, middle temporal and cuneate gyri (p≤0.005; k≥88). HEPF versus LEUF showed greater BOLD activity for BED in inhibitory brain regions: BA 6, middle and superior frontal gyri (p<0.01; k≥119). The groups also differed in the relationships between disinhibition and BOLD activity in the postcentral gyrus (PCG; p=0.04) and ACC-BA 32 (p=0.02). For all participants jointly, PCG BOLD amplitude predicted greater disinhibition (p=0.04). DISCUSSION Food images elicited neural activity indicating attention bias (cuneate & PCG), emotion dysregulation (BA 19 & 32), and disinhibition (MFG, BA6 & SFG) in obese with BED. These may help tailor a treatment for the obesity with BED phenotype.

Abstract
OBJECTIVE Obstructive sleep apnea (OSA), eating psychopathology, and major depressive disorder (MDD) are highly prevalent in patients with severe obesity. Our study aimed to identify differences in binge-eating disorder (BED) prevalence in bariatric surgery candidates with and without OSA. METHODS In this retrospective study, demographic data, psychiatric diagnoses, OSA diagnosis, binge eating, depressive and quality of life (QOL) symptoms were collected from 1,099 bariatric surgery candidates from a Canadian setting. Analysis of variance was used to identify differences in psychopathology and QOL between groups with OSA and BED, BED alone, OSA alone or neither BED or OSA. RESULTS Study participants' mean body mass index was 49.3 kg/m2 and 52.6% had a diagnosis of OSA. Patients with OSA were significantly more likely to have a diagnosis of past BED (χ2 = 6.848, p = .009) and current MDD (χ2 = 5.165, p = .023). Binge-eating (p < .001) and depressive symptoms (p < .001) were significantly higher in patients with co-morbid BED and OSA compared to patients with OSA alone or patients with no diagnosis of BED or OSA. Patients with co-morbid BED and OSA only had significantly lower physical (p < .001) and mental QOL (p = .007) compared to patients with no diagnosis of BED or OSA. DISCUSSION Our findings suggest that patients with a history of BED should be reassessed for OSA. Research is needed to examine whether BED may predispose individuals to developing obesity and OSA.

Abstract
OBJECTIVE A previous study reported that preoperative binge-eating disorder (BED) did not attenuate weight loss at 12 months after bariatric surgery. This report extends the authors' prior study by examining weight loss at 24 months. METHODS A modified intention-to-treat population was used to compare 24-month changes in weight among 59 participants treated with bariatric surgery, determined preoperatively to be free of a current eating disorder, with changes in 33 surgically treated participants with BED. Changes were also compared with 49 individuals with obesity and BED who sought lifestyle modification for weight loss. Analyses included all available data points and were adjusted for covariates. RESULTS At month 24, surgically treated patients with BED preoperatively lost 18.6% of initial weight, compared with 23.9% for those without BED (P = 0.049). (Mean losses at month 12 had been 21.5% and 24.2%, respectively; P = 0.23.) Participants with BED who received lifestyle modification lost 5.6% at 24 months, significantly less than both groups of surgically treated patients (P < 0.001). CONCLUSIONS These results suggest that preoperative BED attenuates long-term weight loss after bariatric surgery. We recommend that patients with this condition, as well as other eating disturbances, receive adjunctive behavioral support, the timing of which remains to be determined.

Abstract
BACKGROUND The best treatment options for binge-eating disorder are unclear. PURPOSE To summarize evidence about the benefits and harms of psychological and pharmacologic therapies for adults with binge-eating disorder. DATA SOURCES English-language publications in EMBASE, the Cochrane Library, Academic OneFile, CINAHL, and ClinicalTrials.gov through 18 November 2015, and in MEDLINE through 12 May 2016. STUDY SELECTION 9 waitlist-controlled psychological trials and 25 placebo-controlled trials that evaluated pharmacologic (n = 19) or combination (n = 6) treatment. All were randomized trials with low or medium risk of bias. DATA EXTRACTION 2 reviewers independently extracted trial data, assessed risk of bias, and graded strength of evidence. DATA SYNTHESIS Therapist-led cognitive behavioral therapy, lisdexamfetamine, and second-generation antidepressants (SGAs) decreased binge-eating frequency and increased binge-eating abstinence (relative risk, 4.95 [95% CI, 3.06 to 8.00], 2.61 [CI, 2.04 to 3.33], and 1.67 [CI, 1.24 to 2.26], respectively). Lisdexamfetamine (mean difference [MD], -6.50 [CI, -8.82 to -4.18]) and SGAs (MD, -3.84 [CI, -6.55 to -1.13]) reduced binge-eating-related obsessions and compulsions, and SGAs reduced symptoms of depression (MD, -1.97 [CI, -3.67 to -0.28]). Headache, gastrointestinal upset, sleep disturbance, and sympathetic nervous system arousal occurred more frequently with lisdexamfetamine than placebo (relative risk range, 1.63 to 4.28). Other forms of cognitive behavioral therapy and topiramate also increased abstinence and reduced binge-eating frequency and related psychopathology. Topiramate reduced weight and increased sympathetic nervous system arousal, and lisdexamfetamine reduced weight and appetite. LIMITATIONS Most study participants were overweight or obese white women aged 20 to 40 years. Many treatments were examined only in single studies. Outcomes were measured inconsistently across trials and rarely assessed beyond end of treatment. CONCLUSION Cognitive behavioral therapy, lisdexamfetamine, SGAs, and topiramate reduced binge eating and related psychopathology, and lisdexamfetamine and topiramate reduced weight in adults with binge-eating disorder.

Abstract
RESUMO Objetivo Realizar revisão sobre transtornos alimentares e comportamentos alimentares transtornados relacionados à cirurgia bariátrica. Métodos Revisão integrativa da literatura nas bases de dados PubMed, Lilacs, Bireme, portal SciELO com descritores indexados com critérios de inclusão: oferecer dado sobre a presença ou frequência de transtorno alimentar e/ou comportamentos alimentares disfuncionais previamente e/ou após a cirurgia. Resultados Foram selecionados 150 estudos (14 nacionais e 136 internacionais): 80,6% eram com avaliação de pacientes pré-/pós-cirúrgicos; 12% eram estudos de caso e 7,3% eram estudos de revisão. Diferentes instrumentos foram usados para avaliação, principalmente o Questionnaire on Eating and Weight Patterns, a Binge Eating Scale e Eating Disorders Examination Questionnaire. A compulsão alimentar foi o comportamento mais avaliado, com frequências/prevalências variando de 2% a 94%; no caso do transtorno da compulsão alimentar as frequências/prevalências variaram de 3% a 61%. Houve também a descrição de anorexia e bulimia nervosa, síndrome da alimentação noturna e comportamento beliscador. Alguns estudos apontam melhora dos sintomas no pós-cirúrgico e/ou seguimento enquanto outros apontam surgimento ou piora dos problemas. Conclusão Apesar da variabilidade entre métodos e achados, comportamentos alimentares disfuncionais são muito frequentes em candidatos à cirurgia bariátrica e podem ainda surgir ou piorar após a intervenção cirúrgica. Profissionais de saúde devem considerar de maneira mais cuidadosa tais problemas neste público, dadas às consequências para o resultado cirúrgico e qualidade de vida.

Abstract
BACKGROUND Preliminary placebo-controlled evidence paved the ground to the US Food and Drug Administration approval extension of lisdexamfetamine for the treatment of moderate-to-severe binge eating disorder (BED) in adults. OBJECTIVES To provide a preliminary qualitative and quantitative synthesis of the placebo-controlled, randomized clinical trials (RCTs) considering the efficacy and tolerability of lisdexamfetamine in the acute and/or maintenance treatment of moderate-to-severe BED in adults. METHODS A preliminary, yet comprehensive, systematic review was performed by accessing a broad range of resources providing publicly available data about lisdexamfetamine at the time of inquiry (March 2016). Study eligibility criteria, participants, and interventions were considered focusing on major clinical and functional outcomes of either efficacy or tolerability of lisdexamfetamine in the treatment of moderate-to-severe BED in adults. RESULTS Meta-analysis of data pooled from three acute RCTs significantly favored lisdexamfetamine over placebo in the reduction of binge eating days/week, Yale-Brown Obsessive Compulsive Scale Modified for Binge Eating total score, weight, response, and remission rates (all, P≤0.01). In contrast, discontinuation rates due to treatment-emergent adverse events were significantly higher among patients in receipt of lisdexamfetamine (relative risk 2.19, P=0.04) versus placebo. LIMITATIONS Publication, selection, performance, attrition, reporting, sponsorship, and "diagnostic shift" biases. Lack of inclusion of adverse event effects other than those requiring discontinuation of the trial(s), as well as lack of information about clinically relevant psychiatric or other medical comorbidities, limits the overall generalizability of pooled results. CONCLUSION Across the included acute phase RCTs, lisdexamfetamine (at 30, 50, or 70 mg/day) led to significant reduction in a number of clinically relevant outcomes compared to placebo. Moreover, safety concerns related to adverse events, high discontinuation rates, and the need for additional long-term maintenance of RCTs solicit careful monitoring of the drug in terms of overall safety and tolerability by further RCTs.

Abstract
Bariatric surgery is the most effective treatment for morbid obesity; however, a subset of patients who undergo this procedure regain weight or achieve suboptimal weight loss results. A large number of studies have examined whether psychological variables play a role in weight loss surgery outcome. Although presurgical psychopathology has been found to be associated with suboptimal results in some studies, this literature is equivocal. These inconsistent findings are reviewed and considered in the context of contemporary models of psychopathology. More specifically, the review focuses on the limitations of atheoretical, descriptive diagnostic systems and examines whether comorbidity within the mood/anxiety disorders, impulse control/substance use disorders and thought disorders can account for the inconsistent findings reported to date. Contemporary models of psychopathology are highlighted and linked to the Research Domain Criteria, which have been advanced by the National Institute of Health. Means for assessing psychological constructs congruent with these models are reviewed. Recommendations are made for standardizing approaches to investigating how psychopathology contributes to suboptimal bariatric surgery outcomes.

Abstract
BACKGROUND Graze eating is defined as repetitive, unplanned eating of small amounts of food throughout the day. Little consensuses exist regarding whether graze eating, like binge eating disorder (BED), is characterized by feelings of loss of control (LOC). Furthermore, little is known about how patients who graze eat with and without LOC differ psychologically. OBJECTIVES The present study seeks to better characterize graze eating by examining differences between graze eating with LOC (+LOC) and without LOC (-LOC) among presurgical bariatric patients. SETTING A large, Midwestern academic medical center. METHODS The sample consisted of 288 adult bariatric surgery candidates (mean age 45.8, standard deviation [SD] 12.57) who underwent a presurgical psychological evaluation. Graze eating, BED, and other mental health diagnoses were evaluated using a semistructured interview. Participants were also administered the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and binge eating scale (BES). Data were collected using a retrospective chart review. RESULTS Among the 33% (n = 95) of the sample who reported preoperative graze eating, 32% (n = 30) also endorsed LOC. Graze eating, particularly with LOC, was associated with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM-IV-TR) diagnoses of anxiety disorders and BED, and multiple measures of internalizing dysfunction on the MMPI-2-RF. CONCLUSIONS Bariatric surgery candidates who graze eat experience a greater degree of overall distress and psychopathology including anxiety and depression. The minority who experience grazing+LOC appear to have even greater risk of psychopathology. Moreover, there appears to be significant overlap with BED. Future research should explore whether these 2 maladaptive eating patterns benefit from similar treatment.

Abstract
This narrative review provides an overview of the epidemiology of binge eating disorder (BED), highlighting the medical history of this disorder and its entry as an independent condition in the Feeding and Eating Disorders section of the recently published Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Estimates of prevalence are provided, as well as recognition that the female to male ratio is lower in BED than in other eating disorders. Evidence is also provided of the most common comorbidities of BED, including mood and anxiety disorders and a range of addiction disorders. In addition, discussion of the viewpoint that BED itself may be an addiction - at least in severe cases - is presented. Although the genetic study of BED is still in its infancy, current research is reviewed with a focus on certain neurotransmitter genes that regulate brain reward mechanisms. To date, a focal point of this research has been on the dopamine and the μ-opioid receptor genes. Preliminary evidence suggests that a predisposing risk factor for BED may be a heightened sensitivity to reward, which could manifest as a strong dopamine signal in the brain's striatal region. Caution is encouraged, however, in the interpretation of current findings, since samples are relatively small in much of the research. To date, no genome-wide association studies have focused exclusively on BED.

Abstract
It is important that clinicians and researchers understand the possible eating-related difficulties experienced by pre-bariatric surgery candidates, as well as their expectations of how their eating and hunger will change after surgery. This review examines English-language publications related to the eating-related behaviours, disorders and expectations of bariatric candidates. Seventy-five articles related to binge eating disorder, grazing, night eating syndrome, emotional eating, food cravings and addiction, and pre-surgical expectations of post-surgical eating in this population were critically reviewed. A variety of often problematic eating behaviours appear more common in bariatric candidates than in non-obese populations. The literature suggests that 4-45% of candidates may have binge eating disorder, 20-60% may graze, 2-42% may have night eating syndrome, 38-59% may engage in emotional eating and 17-54% may fit criteria for food addiction. Binge eating may also be more prevalent in bariatric candidates than in similarly obese non-surgical individuals. Expectations of surgery are high, with pre-surgical candidates believing their bariatric procedure will virtually guarantee significantly improved eating behaviours. Study replications are needed, and further investigation into prevalence, impacts and candidate characteristics related to disordered eating behaviours, as well as candidates' expectations of eating after surgery, will be important. Further comparisons of bariatric candidates to similarly obese non-bariatric populations will be important to understand eating-related characteristics of candidates beyond those related to their weight. Future research may be improved by the use of validated measures, replicable methodologies, minimization of data collected in circumstances where respondents may been motivated to 'fake good', use of prospective data and consistent definitions of key terminology.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) surgery is a very effective bariatric procedure to achieve significant and sustained weight loss, yet little is known about the procedure's impact on the brain. This study examined the effects of RYGB on the brain's response to the anticipation of highly palatable versus regular food. METHODS High fat diet-induced obese rats underwent RYGB or sham operation and were then tested for conditioned place preference (CPP) for the bacon-paired chamber, relative to the chow-paired chamber. After CPP, animals were placed in either chamber without the food stimulus, and brain-glucose metabolism (BGluM) was measured using positron emission tomography (μPET). RESULTS Bacon CPP was only observed in RYGB rats that had stable weight loss following surgery. BGluM assessment revealed that RYGB selectively activated regions of the right and midline cerebellum (Lob 8) involved in subjective processes related to reward or expectation. Also, bacon anticipation led to significant activation in the medial parabrachial nuclei (important in gustatory processing) and dorsomedial tegmental area (key to reward, motivation, cognition and addiction) in RYGB rats; and activation in the retrosplenial cortex (default mode network), and the primary visual cortex in control rats. CONCLUSIONS RYGB alters brain activity in areas involved in reward expectation and sensory (taste) processing when anticipating a palatable fatty food. Thus, RYGB may lead to changes in brain activity in regions that process reward and taste-related behaviors. Specific cerebellar regions with altered metabolism following RYGB may help identify novel therapeutic targets for treatment of obesity.

Abstract
OBJECTIVE We aim to determine how increasing the specificity of binge eating criteria affects the prevalence of self-reported binge eating among presurgical bariatric patients. METHOD 197 women ages 20 to 65 being assessed for bariatric surgery with a BMI greater than 30kg/m(2) were interviewed and completed the Eating and Exercise Examination. RESULTS The prevalence of self-reported binge eating was 55% (n=109). The addition of the criterion 'more than a little loss of control/distress' reduced the rate to 23% (n=45), a minimum of six servings of food reduced the rate to 34% (n=67). The addition of a minimum frequency of twice per week for six months (DSM-VI) reduced the rate to 22% (n=43), or once per week for three months (DSM-5) reduced the rate to 53% (n=104). DISCUSSION More precise definitions and diagnostic criteria for binge eating may result in more consistent reports of prevalence levels of BED.

Replication and evaluation of a proposed two-factor Binge Eating Scale (BES) structure in a sample of bariatric surgery candidates. Surg Obes Relat Dis 2014; 11:659-65.

Abstract
BACKGROUND The Binge Eating Scale (BES) is a widely-used self-report measure of binge eating severity. Hood et al. reported a 2-factor structure for the BES in a sample of bariatric surgery candidates, with factors labeled feelings/cognitions and behavioral manifestations. The present study aims to replicate and extend the factor structure obtained by Hood et al. by testing the utility of a bifactor model that removes binge eating severity variance, which the total BES score purports to assess, in another sample of bariatric surgery candidates. METHODS Bariatric surgery candidates (n = 517; 71.2% women; mean body mass index = 49.50 kg/m(2); SD = 10.17) were sampled. Twenty-four percent met DSM-IV-TR diagnostic criteria for binge eating disorder. RESULTS Consistent with previous research, a 2-factor structure for the BES was supported; however, the 2 factors were substantially correlated (r = .89). A bifactor model significantly improved model fit, supporting the presence of a higher-order severity factor accounting for a significant amount of variance. This factor was primarily marked by binge eating severity as demonstrated by associations with number of objective binge eating episodes and DSM-IV-TR diagnosis. In the bifactor model, the feelings/cognitions factor was modestly associated with self-reported mood psychopathology. However, contrary to expectations, the behavioral manifestation factor was not associated with empirically derived behavioral problems. CONCLUSIONS The current findings partially converge with those of Hood et al. However, the use of the BES as a 2-factor measure is not recommended at this point because of lack of incremental validity demonstrated by the behavioral manifestation factor. Continued use of the BES as a unidimensional measure of binge eating severity, in conjunction with a comprehensive clinical interview, can provide useful guidance for presurgical treatment recommendations.
