RESUMEN
Background: Anorexia nervosa (AN) is a mental and behavioral health condition characterized by an intense fear of weight or fat gain, severe restriction of food intake resulting in low body weight, and distorted self-perception of body shape or weight. While substantial research has focused on general anxiety in AN, less is known about eating-related anxiety and its underlying neural mechanisms. Therefore, we sought to characterize anxiety-to-eat in AN and examine the neurometabolic profile within the dorsal anterior cingulate cortex (dACC), a brain region putatively involved in magnifying the threat response. Methods: Women seeking inpatient treatment for AN and women of healthy weight without a lifetime history of an eating disorder (healthy controls; HC) completed a computer-based behavioral task assessing anxiety-to-eat in response to images of higher (HED) and lower (LED) energy density foods. Participants also underwent magnetic resonance spectroscopy of the dACC in a 3 Tesla scanner. Results: The AN group reported greater anxiety to eat HED and LED foods relative to the HC group. Both groups reported greater anxiety to eat HED foods relative to LED foods. The neurometabolite myo-inositol (mI) was lower in the dACC in AN relative to HC, and mI levels negatively predicted anxiety to eat HED but not LED foods in the AN group only. mI levels in the dACC were independent of body weight, body mass, and general anxiety. Conclusions: These findings provide critical new insight into the clinically challenging feature and underlying neural mechanisms of eating-related anxiety and indicate mI levels in the dACC could serve as a novel biomarker of illness severity that is independent of body weight to identify individuals vulnerable to disordered eating or eating pathology as well as a potential therapeutic target.
RESUMEN
Introduction: Eating disorders (EDs) are conceptualized as disorders of under- and over-control, with impulsivity reflecting under-control. Extant research indicates that impulsivity and related factors such as reward sensitivity and punishment sensitivity may serve as trait-level transdiagnostic risk and/or maintenance factors in EDs. Findings on impulsivity and reward and punishment sensitivity by diagnosis are mixed and research on the relationship between these factors and ED symptoms, hospital course, and treatment outcomes is limited. Methods: Participants (N = 228) were patients admitted to a specialized inpatient behavioral treatment program for EDs who agreed to participate in a longitudinal study and completed self-report measures of impulsivity, reward sensitivity, and punishment sensitivity at admission. Weight and ED symptomatology were measured at admission and discharge. Hospital course variables included length of stay and premature treatment dropout. Results: Impulsivity was lower in individuals with anorexia nervosa (AN) restricting type compared to those with AN binge/purge type or bulimia nervosa; no other group differences were observed. Higher impulsivity was associated with greater bulimic symptoms on the Eating Disorder Inventory 2 (EDI-2) at admission. Impulsivity was not related to ED symptoms, weight outcomes, length of hospital stay, or treatment dropout at program discharge. Conclusion: Impulsivity may help distinguish restrictive versus binge/purge EDs, but does not necessarily relate to discharge outcomes in an intensive inpatient ED program. Findings from this study provide novel contributions to the literature on personality traits in EDs and have important clinical implications. Results suggest that patients with higher levels of impulsivity or reward and punishment sensitivity can be expected to respond to inpatient treatment. Suggestions for future research are discussed.
RESUMEN
OBJECTIVE: Impaired insight and illness denial are common in anorexia nervosa (AN). Missing an AN diagnosis may delay treatment and negatively impact outcomes. METHOD: The current retrospective study examined the prevalence and characteristics of AN symptom non-endorsement (i.e., scoring within the normal range on the Eating Disorder Examination Questionnaire [EDE-Q] or the Eating Disorder Examination [EDE] interview) in three independent samples of hospitalised patients with AN (N1 = 154; N2 = 300; N3 = 194). A qualitative chart review of a subsample of non-endorsers (N4 = 32) extracted reports of disordered eating behaviours observed by the treatment team. RESULTS: The prevalence of non-endorsement ranged from 11% to 34% across sites. Non-endorsers were more likely to be diagnosed with AN restricting type (AN-R) and reported fewer symptoms of co-occurring psychopathology than endorsers. Groups benefitted equally from treatment. The qualitative chart review indicated that objective symptoms of AN were recorded by staff in over 90% of non-endorsers. CONCLUSIONS: Eating disorder symptom assessments using the EDE-Q or EDE may miss symptomatology in up to a third of individuals hospitalised with AN. This study highlights the potential utility of multi-modal assessment including patient interviews, collateral informants, and behavioural observation to circumvent non-endorsement.

OBJECTIVE: Avoidant restrictive food intake disorder (ARFID) has similar prevalence to anorexia nervosa (AN) in adults, but research in this population is lacking. Although inpatient or residential treatment involving nutritional rehabilitation is increasingly recommended for malnourished individuals with ARFID, best practices remain poorly defined. Existing studies on self-reported symptomatology and treatment course and outcome are primarily in child and adolescent cohorts and demonstrate inconsistent findings. This study aimed to compare hospital course and self-reported symptomatology of underweight adult inpatients with ARFID and sex- and age-matched patients with AN. METHOD: Underweight adult patients with ARFID or AN admitted to a specialized, hospital-based behavioral treatment program completed measures of body dissatisfaction, drive for thinness, bulimic symptoms, anxiety, depression, and personality traits. Demographic and treatment course data were abstracted from electronic medical records. Patients with ARFID (n = 69) were matched to those with AN (n = 69) based on sex and age. RESULTS: Adults with ARFID were closer to target weight at admission, but gained weight at a slower rate, were discharged at lower BMI, and were less likely to reach target weight by discharge than adults with AN. Patients with ARFID reported less weight and shape-related eating disorder, state anxiety, and depression symptoms and lower neuroticism. DISCUSSION: Adults with ARFID progress through treatment more slowly and achieve less favorable weight outcomes by hospital discharge than patients with AN, but long-term outcomes are unclear. Describing clinical presentations and course of illness of adult ARFID may help inform treatment protocols.
This study examined hospital course and symptomatology in underweight adults with avoidant/restrictive food intake disorder (ARFID) compared to adults with anorexia nervosa (AN). Both groups were admitted at similar BMI, however compared to patients with AN, those with ARFID gained weight slower and were half as likely to reach target weight by discharge. Adults with ARFID were equally likely, however, to be rated as clinically improved at discharge. Patients with ARFID also reported less symptoms of anxiety, depression or neuroticism than did those with AN, and less weight and shape-related eating disorder symptoms at admission. The reason for slower weight restoration in adults with ARFID may reflect the need for more individualized protocols adapted to meet the unique, often heterogeneous needs of these individuals. Longer-term post-discharge outcomes for adults with ARFID remain unclear and require investigation.
RESUMEN
OBJECTIVE: Parental feeding practices and disordered eating are potential risk factors for the development of disordered eating in children and adolescents. This study measured the relationship between parental dieting behaviours and inpatient treatment outcomes for adolescents with restrictive eating disorders (EDs). METHOD: Parents of adolescents with restrictive EDs (N = 45) admitted to a specialty integrated inpatient-partial hospital meal-based ED treatment programme completed questionnaires assessing parental eating and exercise behaviours. Adolescent clinical data, including percentage median body mass index (%mBMI) at admission and discharge and rate of weight gain, were abstracted from the electronic medical record. RESULTS: Adolescents whose parents reported dieting had a slower rate of weight gain (3.47 lbs./week) compared to participants whose parents were not dieting (4.54 lbs./week; p = 0.017). Additionally, participants whose parents reported dieting had a lower %mBMI at programme discharge (M = 93.56) than participants whose parents did not report dieting (M = 95.99; p = 0.033). CONCLUSION: Parental dieting behaviours may impact an adolescent's response to inpatient ED treatment. Findings suggest a need to assess parental dieting behaviour, and when appropriate, provide additional psychoeducation regarding the potential risks of weight or shape-focussed dialogue and the benefits of modelling adaptive meal behaviours.

OBJECTIVE: Food anxiety and limited dietary variety often persist after intensive treatment for eating disorders (EDs) and may contribute to relapse. Prior studies demonstrate decreased meal-related anxiety with residential or inpatient treatment, but less is known about changes in dietary variety and anxiety associated with specific foods. The current study assessed change in food anxiety and dietary variety in inpatients with EDs (anorexia nervosa and bulimia nervosa) in relation to discharge outcomes from meal-based behavioral treatment. METHOD: Patients (N = 128) admitted to a specialized, hospital-based behavioral treatment program completed measures of food anxiety, dietary variety, and ED symptoms at admission and discharge. Demographic and clinical data were abstracted from electronic medical records. A novel network community analysis identified three food anxiety groups: fruit-veg, animal-based, and carb-based foods. RESULTS: High-energy density combination foods were most anxiety-provoking and most avoided. Food anxiety decreased, and dietary variety increased from admission to discharge. Reduction in food anxiety was associated with lower ED symptom scores and higher normative eating self-efficacy at discharge. For animal-based foods, increased dietary variety was associated with lower food anxiety at discharge. Neither variety nor anxiety was associated with weight restoration. DISCUSSION: Findings highlight the importance of broadening dietary variety and targeting food anxiety during the nutritional rehabilitation and weight restoration phase of ED treatment. Increasing dietary variety may contribute to reduced food anxiety, which, in turn, may increase normative eating self-efficacy. These results may help inform nutritional guidelines for meal-based treatment programs. PUBLIC SIGNIFICANCE: Consuming a greater variety of foods during meal-based intensive treatment may help alleviate food anxiety in patients with eating disorders.

OBJECTIVE: Evaluating treatment efficacy solely on whether sample-level change is statistically significant does not indicate whether clinically significant change (CSC) has occurred at the individual-level. We assessed whether change in measures of eating disorder psychopathology was statistically significant at the sample-level and clinically significant at the individual-level for inpatients treated in a hospital-based eating disorder program. METHOD: Participants (N = 143) were consecutive underweight distinct admissions diagnosed with anorexia nervosa or other specified feeding and eating disorder. The Eating Disorder Examination Questionnaire (EDEQ) and Eating Disorder Recovery Self-efficacy Questionnaire (EDRSQ) were assessed at admission and program discharge. CSC was defined as individual score change that was both statistically reliable and shifted from dysfunctional to normative. RESULTS: Mean EDRSQ and EDEQ scores significantly improved with treatment across the sample; effect sizes were moderate to large. Individual-level analyses demonstrated that 85%, 50%, and 20-35% of participants had CSC or statistically reliable change in BMI, eating symptomatology, and body image respectively. One-third of participants showed CSC on BMI and on at least one self-report measure. DISCUSSION: Individual-level analyses offer more nuanced outcome data that could identify patients at higher risk of relapse who may benefit from adjunctive interventions during or immediately post-discharge. PUBLIC SIGNIFICANCE STATEMENT: This study examined change in eating pathology for inpatients with eating disorders using sample- and individual-level analyses, including whether change was statistically reliable and clinically significant (scores statistically improved and moved into the healthy range). Only half of patients responded robustly to treatment, which may be related to high relapse rates following discharge. Individual-level analyses provided a detailed view of treatment response and may identify patients at higher relapse risk.

OBJECTIVE: The COVID-19 pandemic has been associated with increased hospitalization rates and worsened symptom severity in patients with eating disorders (ED), but most studies focused exclusively on adolescents. Further, research evaluating the impact of COVID-19 on response to inpatient treatment for ED is limited. This study aimed to compare demographic characteristics, symptom severity at admission, and discharge outcomes for adult and adolescent inpatients with EDs admitted before and after onset of the COVID-19 pandemic. We expected the post-COVID cohort would report elevated symptomatology and poorer response to treatment compared to the pre-COVID cohort and that this effect would be amplified for adolescents. METHOD: Patients were consecutively hospitalized adults and adolescents treated in a specialized behavioral integrated inpatient-partial hospitalization program for eating disorders between March 2018 and March 2022 (N = 261). RESULTS: The effect of COVID-19 on symptomatology was moderated by age group such that adolescents in the post-COVID cohort, but not adults, reported higher levels of eating disorder and depressive symptoms compared to the pre-COVID cohort. No group differences were observed for discharge outcomes (rate of weight gain, length of stay, or percent target weight). DISCUSSION: Findings with respect to elevated symptomatology in adolescents but not adults may reflect the particularly negative impact of social isolation on adolescents. Future research is needed to assess the impact of COVID-19 on long-term treatment outcomes including relapse at 1-year, as well as the potential impact of COVID-19 on treatment availability for chronically ill adults or those with public insurance. PUBLIC SIGNIFICANCE: Patients with eating disorders (ED) admitted to a specialty inpatient program after the start of the COVID-19 pandemic were younger and more likely to be male than those admitted pre-pandemic. Adolescents admitted post-COVID, but not adults, reported elevated ED and depressive symptoms compared to the pre-COVID cohort. Group differences were not observed for treatment response. Future research should evaluate the impact of COVID-19 on relapse risk in EDs.

PURPOSE OF REVIEW: A growing body of research suggests psychedelic-assisted therapy (PAT) may be safe and effective for a variety of mental health conditions. Among these, eating disorders have been a recent target of interest. This review provides an up-to-date summary of the potential mechanisms and use of PAT in people diagnosed with eating disorders, with a focus on anorexia nervosa. RECENT FINDINGS: Classic psychedelics may have transdiagnostic efficacy through several mechanisms relevant to eating disorder pathology. Interest in, and efforts to increase access to PAT are both high. Early clinical trials are focused on establishing the safety and utility of this treatment in eating disorders, and efficacy remains unclear. High-quality published data to support the use of PAT for people with eating disorders remains lacking. Recent studies however suggest PAT has the potential to augment the efficacy of current interventions for these difficult-to-treat conditions.

PURPOSE: Hypoglycemia, a complication of prolonged starvation, can be life-threatening and is presumed to contribute to the high mortality of anorexia nervosa. Furthermore, early refeeding in severe anorexia nervosa can precipitate paradoxical post-prandial hypoglycemia. Few studies have analyzed the course of hypoglycemia during nutritional rehabilitation in patients with extremely low-weight anorexia nervosa. No standard practice guidelines exist and recommended strategies for managing hypoglycemia (i.e., nasogastric feeds, high-fat diets) have limitations. METHODS: This cohort study assessed prevalence and correlates of hypoglycemia in 34 individuals with very low body mass index (BMI < 14.5 kg/m2) anorexia nervosa treated in an intensive eating disorders program with an exclusively meal-based rapid weight gain nutritional protocol. Hypoglycemia was monitored with frequent point of care (POC) glucose testing and treated with oral snacks and continuous slow intravenous 5% dextrose in 0.45% saline (IV D5 1/2 NS) infusion. RESULTS: POC hypoglycemia was detected in 50% of patients with highest prevalence noted on the day of admission. Hypoglycemia resolved during the first week of hospitalization in most cases and was generally asymptomatic. Seven patients (20.6%) experienced at least one episode of severe hypoglycemia with POC glucose < 50 mg/dl. Lower admission BMI was associated with higher likelihood of developing hypoglycemia and longer duration of hypoglycemia. CONCLUSION: Meal-based management of hypoglycemia supplemented by continuous IV D5 1/2 NS appears a viable alternative to alternate strategies such as enteral tube feeding. We discuss recommendations for hypoglycemia monitoring during nutritional rehabilitation and directions for future research. LEVEL OF EVIDENCE: Level III, retrospective cohort study.

A recent article (JED 10:23, 2022) proposed defining terminal anorexia to improve access to palliative and hospice care, and to medical aid in dying for a minority of patients with severe and enduring anorexia nervosa (SE-AN). The authors presented three cases and, for two, the first author participated in their death. Anorexia nervosa is a treatable psychiatric condition for which recovery may be uncertain. We are greatly concerned however regarding implications of applying the label "terminal" to anorexia nervosa and the risk it will lead to unjustified deaths in individuals whose mental illness impairs their capacity to make a reasoned treatment decision.
RESUMEN
Cannabis effects are predominantly mediated by pharmacological actions on cannabinoid type 1 (CB1 ) receptors. Prior positron emission tomography (PET) studies in individuals who use cannabis included almost exclusively males. PET studies in females are needed because there are sex differences in cannabis effects, progression to cannabis use disorder (CUD), and withdrawal symptom severity. Females with CUD (N = 10) completed two double-blind cannabis smoking sessions (Session 1: placebo; Session 2: active), and acute cannabis effects were assessed. After Session 2, participants underwent 3 days of monitored cannabis abstinence; mood, craving, and withdrawal symptoms were assessed and a PET scan (radiotracer: [11 C]OMAR) followed. [11 C]OMAR Distribution volume (VT ) from these participants was compared with VT of age/BMI-similar female non-users of cannabis ("healthy controls"; N = 10). VT was also compared between female and male healthy controls (N = 7). Females with CUD displayed significantly lower VT than female healthy controls in specific brain regions (hippocampus, amygdala, cingulate, and insula). Amygdala VT was negatively correlated with mood changes (anger/hostility) during abstinence, but VT was not correlated with other withdrawal symptoms or cannabis effects. Among healthy controls, females had significantly higher VT than males in all brain regions examined. Chronic cannabis use appears to foster downregulation of CB1 receptors in women, as observed previously in men, and there are inherent sex differences in CB1 availability. Future studies should elucidate the time course of CB1 downregulation among females who use cannabis and examine the relation between CB1 availability and cannabis effects among other populations (e.g., infrequent users; medicinal users).

Anorexia nervosa (AN) is a disorder characterized by rigid and restrictive eating behaviors, resulting in significantly low body weight. While specialized behavioral intensive treatment programs can reliably support individuals with AN to normalize eating and weight control behaviors and achieve weight restoration, prognostic factors predicting relapse following treatment are unclear. We examined whether changes in (i) normative eating self-efficacy, (ii) body image self-efficacy, (iii) drive for thinness, and (iv) body dissatisfaction from inpatient admission to six-month follow-up were associated with weight restoration status at program discharge and at six-month follow-up. The sample comprised 146 participants with AN admitted to a meal-based inpatient-partial hospitalization program. Participants completed questionnaires at inpatient admission and six months following program discharge. Additionally, at follow-up, participants reported the frequency of engaging in normalized eating behaviors since discharge (e.g. eating with others and preparing a balanced meal). The majority (73.3%) of participants attained a BMI > 19 at discharge and 59.6% were weight restored at six-month follow-up. Change in normative eating self-efficacy was significantly associated with weight restoration at follow-up, whereas change in body image self-efficacy, drive for thinness, and body dissatisfaction were not. For each one unit increase in normative eating self-efficacy, patients were 4.65 times more likely to be weight restored at follow-up (p = .002). Additionally, individuals reporting a higher frequency of normalized eating behaviors at follow-up were more likely to be weight restored. Normative eating self-efficacy and normalized eating behaviors may represent vital treatment targets for relapse prevention interventions for this high-risk population.

OBJECTIVE: Gastrointestinal (GI) concerns are often presumed to complicate nutritional rehabilitation for restrictive eating disorders, yet their relationship to weight restoration outcomes is unclear. This retrospective chart review examined GI history and weight-related discharge outcomes in primarily adult, underweight inpatients with anorexia nervosa (AN, N = 107) or avoidant/restrictive food intake disorder (ARFID, N = 22) treated in a meal-based, behavioral eating disorder program. METHOD: Lifetime GI symptomatology, diagnoses, diagnostic tests, and procedures were abstracted from medical records. Generalized linear models examined associations of GI diagnoses, tests, and procedures with discharge BMI and rate of weight gain. RESULTS: Ninety-nine percent of patients reported GI symptomatology and 83% had one or more GI diagnoses; with constipation and GERD most common. GI diagnoses (p <.01) and testing (p <.001) were more common in ARFID than AN. Average inpatient weight gain (1.59 kg/week), and discharge BMI (18.5 kg/m2 ), did not differ by group. Slower weight gain in patients with (1.3 kg/week), versus without (1.7 kg/week), history of tube feeding (p = .02), accounted for a main effect of GI procedures on inpatient rate of gain (p = .01). DISCUSSION: Despite ubiquitous GI symptomatology, meal-based weight restoration achieved average weekly weight gain above recommended APA guidelines for hospitalized patients with an eating disorder. History of tube feeding was associated with slower mean weight gain, which remained, however, within recommended APA guidelines.

Use of force in the care of patients with severe anorexia nervosa is controversial but can be justified when the disorder becomes life-threatening. This commentary examines the role of force in compassionate care of an adolescent patient hospitalized with extreme anorexia nervosa and suggests strategies for reaching consensus, minimizing harm, and maximizing the chance of a therapeutic outcome when forced intervention is a compassionate thing to do.

Proposed treatments for severe and enduring anorexia nervosa (SE-AN) focus on quality of life, and psychological and social functioning. By de-emphasizing weight restoration as a priority, however, premature diagnosis of SE-AN may reduce potential for recovery. The present study assessed the effect of weight restoration, illness duration, and severity on treatment outcome 6 months after discharge from an intensive, meal-based behavioral treatment program. Participants included hospitalized adult women (N = 191) with AN or underweight other specified feeding and eating disorder (OSFED). Participants were characterized as short-term (ill <7 years; n = 74) or long-term ill (ill ≥ 7 years; n = 117). Compared with short-term ill, long-term ill patients were older, had lower lifetime body mass index (BMI), more prior admissions, and exhibited greater depression and neuroticism. Long-term vs. short-term ill patients gained weight at the same rate (~2 kg/wk) and were equally likely to be weight restored by discharge (>75% reached BMI ≥ 19 kg/m2 in both groups). At 6-month follow-up (n = 99), both groups had equivalent self-reported BMI, and depression, drive for thinness, body dissatisfaction, and bulimia scores. The only predictor of BMI ≥ 19 kg/m2 at follow-up was discharge BMI. The likelihood of a BMI ≥ 19 kg/m2 at follow-up was 5-fold higher for those with discharge BMI ≥ 19 kg/m2. Few studies of long-term ill inpatients with AN have examined the impact of full weight restoration on short-term outcomes. This study supports the therapeutically optimistic stance that, regardless of illness duration, hospitalized patients with AN benefit from gaining weight to a BMI ≥ 19 kg/m2.
RESUMEN
OBJECTIVE: Safe, tolerable, effective approaches to weight restoration are needed for adults with anorexia nervosa (AN). We examined weight outcomes and patient satisfaction with an integrated, inpatient-partial hospitalization, meal-based behavioral program that rapidly weight restores a majority of patients. METHOD: Consecutively discharged inpatients (N = 149) treated on weight gain protocol completed an anonymous questionnaire assessing treatment satisfaction at inpatient discharge. Responders (107/149) rated their satisfaction with program components, feeling included in treatment, and likelihood of returning, or recommending the program to others. Clinical and demographic data were abstracted by chart review on all cases. RESULTS: Over 70% of adult patients met BMI≥19 kg/m2 by program discharge. Mean inpatient rate of gain was 1.85 kg/week (SD = 0.89). A majority (83.2%) would recommend the program to others and 71.4% endorsed a willingness to return if needed. The behavioral treatment focus was rated highly by 82.9% of respondents and was the strongest predictor of likelihood of referring others. DISCUSSION: Results indicate a behaviorally focused, integrated, meal-based specialty program for eating disorders that includes rapid weight gain is acceptable to most participants. Data have implications for quality care, outcome reporting, and cost-effectiveness of inpatient behavioral weight restoration programs for individuals with AN.

BACKGROUND: Bariatric surgery is currently the most effective treatment for obesity. However, outcomes vary and disordered eating may persist or emerge postsurgically. Severe postsurgical eating disorders may require inpatient treatment, and guidelines for the modification of inpatient nutritional treatment protocols for this population are lacking. OBJECTIVES: This paper describes a modified inpatient nutritional protocol for postsurgical patients with eating disorders treated on a behavioral eating disorders unit, and reports patient characteristics and treatment response. SETTINGS: This research was conducted at a university hospital. METHODS: Cases (n = 19) comprised 2% of all eating disorder admissions; 5 were underweight and required weight restoration. Clinical data collected via chart review included disordered eating behaviors, medical and psychiatric co-morbidity, and treatment course. RESULTS: All cases were status post Roux-en-Y gastric bypass (median 5 yr postsurgery). Onset of disordered eating preceded surgery in the majority, and intentional vomiting was the most commonly reported postsurgical disordered eating behavior. The sample was notable for a high level of psychiatric and medical co-morbidity. Patients responded well to the modified treatment protocols, with a majority of patients on the weight gain (60%) and weight maintenance (78%) post-bariatric surgery protocols discharged for clinical improvement. CONCLUSIONS: Postsurgical bariatric patients with eating disorders can be successfully treated on a specialized eating disorders unit. Modification of inpatient eating disorder protocols for those who have undergone bariatric surgery is necessary to address the different physiologic needs of this patient population while providing them with effective psychiatric care.
