Abstract
OBJECTIVE Sparse research informs how caloric prescriptions should be advanced during nutritional rehabilitation of inpatients with anorexia nervosa (AN). This study compared the impact of a standardized caloric increase approach, in which increases occurred on a predetermined schedule, to an individualized approach, in which increases occurred only following insufficient weight gain, on rate, pattern, and cumulative amount of weight gain and other weight restoration outcomes. METHOD This study followed a natural experiment design comparing AN inpatients consecutively admitted before (n = 35) and after (n = 35) an institutional change from individualized to standardized caloric prescriptions. Authors examined the impact of prescription plan on weekly weight gain in the first treatment month using multilevel modeling. Within a subsample remaining inpatient through weight restoration (n = 40), multiple regressions examined the impact of caloric prescription plan on time to weight restoration, length of hospitalization, maximum caloric prescription, discharge BMI, and incidence of activity restriction and edema. RESULTS There were significant interactions between prescription plan and quadratic time on average weekly weight gain (p = .03) and linear time on cumulative weekly weight gain (p < .001). Under the standardized plan, patients gained in an accelerated curvilinear pattern (p = .04) and, therefore, gained cumulatively greater amounts of weight over time (p < .001). Additionally, 30% fewer patients required activity restriction under the standardized plan. DISCUSSION Standardized caloric prescriptions may confer advantage by facilitating accelerated early weight gain and lower incidence of bedrest without increasing the incidence of refeeding syndrome.

Abstract
OBJECTIVE Eating behavior during meals in anorexia nervosa (AN) has long been noted to be abnormal, but little research has been done carefully characterizing these behaviors. These eating behaviors have been considered pathological, but are not well understood. The current study sought to quantify ingestive and non-ingestive behaviors during a laboratory lunch meal, compare them to the behaviors of healthy controls (HC), and examine their relationships with caloric intake and anxiety during the meal. METHOD A standardized lunch meal was video-recorded for 26 individuals with AN and 10 HC. Duration, frequency, and latency of 16 mealtime behaviors were coded using computer software. Caloric intake, dietary energy density (DEDS), and anxiety were also measured. RESULTS Nine mealtime behaviors were identified that distinguished AN from HC: staring at food, tearing food, nibbling/picking, dissecting food, napkin use, inappropriate utensil use, hand fidgeting, eating latency, and nibbling/picking latency. Among AN, a subset of these behaviors was related to caloric intake and anxiety. DISCUSSION These data demonstrate that the mealtime behaviors of patients with AN and HC differ significantly, and some of these behaviors may be associated with food intake and anxiety. These mealtime behaviors may be important treatment targets to improve eating behavior in individuals with AN.

Abstract
The neurobiology of anorexia nervosa remains incompletely understood. Here we utilized PET imaging with the radiotracer [(11)C]raclopride to measure striatal dopamine type 2 (D2) receptor availability in patients with anorexia nervosa. 25 women with anorexia nervosa who were receiving treatment in an inpatient program participated, as well as 25 control subjects. Patients were scanned up to two times with the PET tracer [(11)C]raclopride: once while underweight, and once upon weight restoration. Control subjects underwent one PET scan. In the primary analyses, there were no significant differences between underweight patients (n=21) and control subjects (n=25) in striatal D2 receptor binding potential. Analysis of subregions (sensorimotor striatum, associative striatum, limbic striatum) did not reveal differences between groups. In patients completing both scans (n=15), there were no detectable changes in striatal D2 receptor binding potential after weight restoration. In this sample, there were no differences in striatal D2 receptor binding potential between patients with anorexia nervosa and control subjects. Weight restoration was not associated with a change in striatal D2 receptor binding. These findings suggest that disturbances in reward processing in this disorder are not attributable to abnormal D2 receptor characteristics, and that other reward-related neural targets may be of greater relevance.

Abstract
OBJECTIVE There is growing interest in the role of emotion regulation in anorexia nervosa (AN). Although anxiety is also hypothesized to impact symptoms of AN, little is known about how emotion regulation, anxiety, and eating disorder symptoms interact in AN. In this study, we examined the associations between emotion regulation, anxiety, and eating disorder symptom severity in AN. METHODS Questionnaires and interviews assessing emotion regulation difficulties, anxiety, eating disorder symptoms, and eating disorder-related clinical impairment were collected from group of underweight individuals with AN (n=59) at admission to inpatient treatment. Hierarchical linear regressions were used to examine the associations of emotion regulation difficulties, anxiety, and the interaction of these constructs with eating disorder symptoms and eating disorder-related clinical impairment. RESULTS Emotion regulation difficulties were significantly positively associated with eating disorder symptoms and related clinical impairment only when anxiety levels were low and anxiety was significantly positively associated with eating disorder symptoms and related clinical impairment only when emotion regulation problems were not elevated. CONCLUSIONS This study adds to a growing literature suggesting that emotion regulation deficits are associated with eating disorder symptoms in AN. Certain individuals with AN may especially benefit from a focus on developing emotion regulation skills in the acute stages of illness.

Abstract
OBJECTIVE This study examined: (1) changes in emotion regulation difficulties in underweight inpatients with anorexia nervosa (AN) following weight restoration, (2) differences in emotion regulation between AN subtypes at acute and weight-restored stages of illness. METHOD Repeated measure analyses of variance examined changes in scores on the Difficulties in Emotion Regulation Scale (DERS; Gratz and Roemer, J Psychopathol Behav Assess, 26, 41-54, 2004) and other clinical variables in a group of inpatients with AN from hospital admission (N = 65) to weight restoration (N = 51). Correlations between BMI and DERS scores at both time points were examined. Emotion regulation difficulties were compared between individuals with AN, restricting type (AN-R) and AN, binge/purge type (AN-BP) at both time points using multivariate analysis of covariance. RESULTS All clinical variables, except for the DERS, significantly improved with weight restoration (p < .001). There were no associations between BMI and DERS prior to or after weight restoration and AN subtypes did not significantly differ in emotion regulation difficulties. DISCUSSION Unlike other clinical variables, emotion regulation difficulties in AN did not improve with weight restoration. In addition, both subtypes of AN appear to have similar difficulties with emotion regulation. The treatment of AN might be enhanced by focusing on improving emotion regulation abilities.

Abstract
OBJECTIVE Anorexia nervosa (AN) is a severe illness with high rates of relapse. Exposure and Response Prevention for AN (AN-EXRP) is a new approach that specifically addresses maladaptive eating behavior by targeting eating-related fear and anxiety. The aim of this study was to evaluate AN-EXRP as an adjunctive strategy to improve eating behavior during weight restoration, at a pivotal moment when treatment goals shift toward relapse prevention. METHOD A randomized controlled trial was conducted to compare AN-EXRP with a comparison condition, Cognitive Remediation Therapy (CRT). Hospitalized patients with AN (n = 32) who had achieved weight restoration to a BMI > 18.5 kg/m(2) received 12 sessions of either AN-EXRP or CRT. Outcome was assessed by change in caloric intake in an objective assessment of eating behavior. RESULTS The average test meal caloric intake of participants who received AN-EXRP increased from 352 ± 263 kcal at baseline to 401 ± 215 kcal post-treatment, while that of participants who received CRT decreased from 501 ± 232 kcal at baseline to 424 ± 221 kcal post-treatment [t(28) = 2.5, p = .02]. Improvement in intake was significantly associated with improvement in eating-related anxiety (Spearman's ρ = 0.40, p = .03). DISCUSSION These data demonstrate that AN-EXRP, compared to a credible comparison intervention, is associated with better caloric intake in a laboratory meal over time in AN. Additional studies are required to determine whether incorporation of these techniques into a longer treatment program leads to enduring and clinically significant change.

Abstract
OBJECTIVE Avoidance of dietary fat is a highly characteristic eating behavior of individuals with anorexia nervosa (AN). To date, no study has determined whether these individuals are better able to perceive the fat content of foods than individuals without AN. The goal of this study was to compare blinded taste ratings of fat-free, low fat, and regular cream cheese in patients with AN and in normal controls (NC). METHOD AN (n = 25) and control (NC; n = 25) participants were presented with a series of nine cream cheese samples of three differing fat contents and asked to taste and rate each sample from very low to very high fat. RESULTS Repeated measures ANOVA found no significant main effect of fat content and no interaction between fat content and diagnosis; however, a significant three-way interaction between fat content, diagnosis, and trial was observed. Post hoc analysis revealed a significant fat content by trial interaction within the AN group, suggesting a significant trial effect for the fat-free samples only with improving ability to detect fat-free samples over repeated trials. DISCUSSION The current study suggests that individuals with AN do not have a markedly greater ability to taste fat than NC, and that; therefore, fat avoidance is likely primarily based on cognitive factors.

Abstract
The aim of this paper is to review recent literature on suicide and self-injury in eating disorders (ED) including anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Among psychiatric diagnoses, EDs are associated with increased mortality rates, even when specialized treatment is available. Of the mortalities that are reported in individuals with EDs, suicide is among the most commonly reported causes of death. Additionally, suicidal and non-suicidal self-injurious behaviors occur frequently in this clinical population. A literature search was undertaken using the databases of Medline/PubMed and PsycInfo to identify papers describing suicidality in individuals with ED diagnoses. The authors identified studies and review articles published between 2005-2013 (inclusive) that describe the relationship between EDs and suicide, and associated behaviors including self-injurious behaviors, or non-suicidal self-injury (NSSI). The initial search resulted in 1095 papers that met the a priori search criteria. After careful review, 66 papers were included. The majority of papers described clinical cohorts that were studied longitudinally. The diagnosis described most frequently in selected studies was AN. There are limited current data about the prevalence of suicide and NSSI among individuals with EDs. Among the published studies that focus specifically on the relationship between EDs and suicidality, most describe AN in more detail than other EDs. Nonetheless, rates of mortality, and specifically rates of suicide, are undeniably high in ED populations, as are the rates of self-harm. Therefore, it is critical for clinicians and caretakers to carefully evaluate these patients for suicide risk and to refer promptly for appropriate treatment.

Abstract
OBJECTIVE Bulimia nervosa (BN) has been characterized as similar to an addiction, though the empirical support for this characterization is limited. This study utilized PET imaging to determine whether abnormalities in brain dopamine (DA) similar to those described in substance use disorders occur in BN. METHOD PET imaging with [(11) C]raclopride, pre/post methylphenidate administration, to assess dopamine type 2 (D(2)) receptor binding (BP(ND)) and striatal DA release (ΔBP(ND)). RESULTS There was a trend toward lower D(2) receptor BP(ND) in two striatal subregions in the patient group when compared with the control group. DA release in the putamen in the patient group was significantly reduced and, overall, there was a trend toward a difference in striatal DA release. Striatal DA release was significantly associated with the frequency of binge eating. DISCUSSION These data suggest that BN is characterized by abnormalities in brain DA that resemble, in some ways, those described in addictive disorders.

Abstract
OBJECTIVE Anorexia nervosa (AN) is a severe mental illness with high rates of relapse and rehospitalization. New treatment approaches are needed. We aimed to evaluate the potential utility of addressing eating-related fear in the treatment of AN using psychotherapy techniques known to be effective in the treatment of anxiety disorders and obsessive compulsive disorder, namely exposure therapy and response prevention. METHOD We developed a brief treatment intervention for AN (AN-EXRP) and evaluated its effects in an open series of nine individuals with AN towards the end of acute weight restoration. We focused on eating behavior as the primary outcome, as it is related both to anxiety and to longer term course. RESULTS Change in anxiety with AN-EXRP was associated with greater caloric intake. DISCUSSION These findings support the anxiety-centered model of AN and suggest the potential utility of further developing this treatment approach.

Abstract
The proposed DSM-5 classification scheme for eating disorders includes both major and minor changes to the existing DSM-IV diagnostic criteria. It is not known what effect these modifications will have on the ability to make reliable diagnoses. Two studies were conducted to evaluate the short-term test-retest reliability of the proposed DSM-5 eating disorder diagnoses: anorexia nervosa, bulimia nervosa, binge eating disorder, and feeding and eating conditions not elsewhere classified. Participants completed two independent telephone interviews with research assessors (n=70 Study 1; n=55 Study 2). Fair to substantial agreements (κ=0.80 and 0.54) were observed across eating disorder diagnoses in Study 1 and Study 2, respectively. Acceptable rates of agreement were identified for the individual eating disorder diagnoses, including DSM-5 anorexia nervosa (κ's of 0.81 to 0.97), bulimia nervosa (κ=0.84), binge eating disorder (κ's of 0.75 and 0.61), and feeding and eating disorders not elsewhere classified (κ's of 0.70 and 0.46). Further, improved short-term test-retest reliability was noted when using the DSM-5, in comparison to DSM-IV, criteria for binge eating disorder. Thus, these studies found that trained interviewers can reliably diagnose eating disorders using the proposed DSM-5 criteria; however, additional data from general practice settings and community samples are needed.

Abstract
OBJECTIVE To replicate our previous findings of an association between energy density and diet variety in recently weight-restored patients with anorexia nervosa (AN) and clinical outcome in the year following treatment. METHOD Nineteen hospitalized, weight-restored women with AN completed a food record, from which a diet energy density score (DEDS) and a diet variety score (DVS) were calculated. After hospital discharge, patients were contacted regularly; at the end of one year, clinical outcome was determined using modified Morgan-Russell criteria. As in our previous study, outcome was dichotomized into "full, good, or fair" and "poor" groups. RESULTS Data from 16 subjects were available. The DEDS was significantly lower (p < .05) in the poor outcome group (0.7 ± 1) compared with the "full, good, or fair" outcome group (0.9 ± 1). Although the DVS was also lower in the poor outcome group (13.9 ± 2) compared with the "full, good or fair" outcome group (15.7 ± 1.8), this difference was not statistically significant. DISCUSSION In recently weight-restored patients with AN, a lower DEDS, but not DVS, is associated with poor clinical outcome after inpatient treatment. This finding may be important in the assessment of risk for relapse in patients with AN.

Abstract
BACKGROUND Anorexia nervosa (AN) is a serious psychiatric illness associated with significant morbidity and mortality. There is little empirical support for specific treatments and new approaches are sorely needed. This two-site study aimed to determine whether olanzapine is superior to placebo in increasing body mass index (BMI) and improving psychological symptoms in out-patients with AN. METHOD A total of 23 individuals with AN were randomly assigned in double-blind fashion to receive olanzapine or placebo for 8 weeks together with medication management sessions that emphasized compliance. Weight, other physical assessments and measures of psychopathology were collected. RESULTS End-of-treatment BMI, with initial BMI as a covariate, was significantly greater in the group receiving olanzapine [F(1, 20)=6.64, p=0.018]. Psychological symptoms improved in both groups, but there were no statistically significant group differences. Of the 23 participants, 17 (74%) completed the 8-week trial. Participants tolerated the medication well with sedation being the only frequent side effect and no adverse metabolic effects were noted. CONCLUSIONS This small study suggests that olanzapine is generally well tolerated by, and may provide more benefit than placebo for out-patients with AN. Further study is indicated to determine whether olanzapine may affect psychological symptoms in addition to BMI.

Abstract
OBJECTIVE Across studies, adolescents score lower on measures of eating disorder pathology than adults, but it is unclear whether such findings reflect discrepancies inherent to site/study or true developmental differences. The aim of this study was to determine whether age predicts subscale and diagnostic scores of the Eating Disorder Examination (EDE) in adolescents and adults with anorexia nervosa (AN) admitted to a single research center within the same period of time. METHOD The sample consisted of 16 adolescent and 20 adult consecutive admissions to parallel, age-specific, research-based AN treatment programs. Participants completed a baseline evaluation at admission that included the EDE, depression measures, and global assessment of functioning scales. RESULTS Age significantly predicted EDE scores in univariate regression analyses. However, in multivariate models that included severity indices of general and specific psychopathology as covariates, age was no longer a significant predictor of severity of eating disorder symptoms. DISCUSSION This study adds to the growing body of data showing lower scores on the EDE for adolescents with AN relative to their adult counterparts, while eliminating potential site confounds. Results indicate that the higher adult scores may be carried in part by a more overall severe and chronic general clinical profile.

Abstract
Anorexia nervosa is a serious psychiatric illness associated with substantial morbidity and mortality. Weight-restored females with anorexia nervosa with limited diet variety, assessed by a diet variety score, have been reported to have poor outcomes. Using the same patient cohort, the objective of the current study was to provide a detailed description of the types of foods from which patients restrict variety in their diets. Forty-one weight-restored patients, hospitalized between June 2000 and July 2005, who completed a 4-day food record before discharge were followed for up to 1 year. Patient outcomes were categorized as a success (n=29) or failure (n=12) using Morgan-Russell criteria. Although the total number of foods selected did not differ between the success and failure groups (73±14 vs 74±13, respectively; P=0.741), a significant difference in the total number of different foods was observed: the failure group selected fewer and the success group selected more (43±9 vs 51±7; P=0.005). Outcomes groups also differed significantly in the variety of foods selected from 5 of 17 food groups. Results suggest that a diet limited in total variety and specifically limited in variety from five food groups may be associated with relapse in patients with anorexia nervosa.

Abstract
Eating disorders are serious psychiatric illnesses that often present during adolescence and young adulthood. They are associated with medical as well as psychological disturbances, and pediatricians play an important role in their identification, diagnosis, and management. There has been a paucity of treatment research that specifically focuses on children and adolescents with eating disorders. This article reviews the scientific evidence for the use of psychotropic medication in the treatment of children and adolescents with eating disorders.

Abstract
OBJECTIVE This study examined the frequency and characteristics of alli use among patients in eating disorder treatment facilities. METHOD Patients from five treatment centers completed the Survey of Eating and Related Behaviors. Diagnoses were determined from survey responses. RESULTS Of 417 survey respondents, 26 (6.2%) reported a history of alli use. Of those, 15 (57.7%) met criteria for an eating disorder, including one of 29 patients (3.4%) with anorexia nervosa binge-purge subtype, six of 66 patients (9.1%) with full or subthreshold bulimia nervosa, four of 49 (8.2%) with binge eating disorder, one of six (16.7%) with purging disorder, and three of 80 (3.8%) with an eating disorder not otherwise specified. DISCUSSION The results of this survey suggest that patients with eating disorders use alli, albeit relatively uncommonly. Therefore, it is worthwhile for clinicians to inquire about alli use when evaluating or treating these patients in any clinical setting.

Abstract
BACKGROUND Body image distortions are a core feature of anorexia nervosa (AN). We, and others, previously reported abnormalities in adipose tissue distribution after acute weight restoration in adult women with AN compared with body mass index-matched healthy control women. Whether these abnormalities persist over time remains unknown. OBJECTIVES We aimed to 1) replicate previous findings that showed preferential central accumulation of adipose tissue in recently weight-restored AN women compared with control subjects, 2) describe the change within patients with longer-term (1-y) weight maintenance, and 3) compare adipose tissue distribution after 1-y maintenance with that of control subjects. DESIGN Body composition and adipose tissue distribution were assessed by whole-body magnetic resonance imaging in women with AN shortly after weight normalization (n = 30) and again 1 y after hospital discharge (n = 16) and in 8 female control subjects at 2 time points. RESULTS With acute weight restoration, AN patients had significantly greater visceral and intermuscular adipose tissue compared with control women [visceral: 0.75 +/- 0.26 compared with 0.51 +/- 0.26 kg in AN patients and controls, respectively (P = 0.02); intermuscular: 0.46 +/- 0.17 compared with 0.29 +/- 0.13 kg in AN patients and controls, respectively (P = 0.01)]. With maintenance of normal weight for approximately 1 y, visceral adipose tissue distribution in AN patients was not different from that in healthy control subjects. CONCLUSIONS In adult women with AN, normalization of weight in the short term is associated with a distribution of adipose tissue that is consistent with a central adiposity phenotype. This abnormal distribution appears to normalize within a 1-y period of weight maintenance. This research was registered at clinicaltrials.gov as NCT 00271921 and NCT 00368667.

Abstract
OBJECTIVE The removal of the amenorrhea criterion for anorexia nervosa (AN) is being considered for the fifth edition of The Diagnostic and Statistical Manual (DSM-V). This article presents and discusses the arguments for maintaining as well as those for removing the criterion. METHOD The psychological and biological literatures on the utility of amenorrhea as a distinguishing diagnostic criterion for AN and as an indicator of illness severity are reviewed. RESULTS The findings suggest that the majority of differences among patients with AN who do and do not meet the amenorrhea criterion appear largely to reflect nutritional status. Overall, the two groups have few psychological differences. There are mixed findings regarding biological differences between those with AN who do and do not menstruate and the relationship between amenorrhea and bone health among patients with AN. DISCUSSION Based on these findings, one option is to describe amenorrhea in DSM-V as a frequent occurrence among individuals with AN that may provide important information about clinical severity, but should not be maintained as a core diagnostic feature. The possibilities of retaining the criterion or eliminating it altogether are discussed.
