RESUMEN
BACKGROUND: End-of-life (EOL) care is the part of palliative care intended for persons nearing death. In anorexia nervosa (AN), providing EOL care instead of coercing life-sustaining measures is controversial. The existing literature has not been synthesized yet. To clearly delineate differing views and identify open questions as well as areas of possible consensus, we conducted the first-ever synthesis of the existing literature. METHODS: We searched EMBASE, PubMed, PsycInfo, and Web of Science for scientific publications on forgoing coerced life-sustaining measures and/or providing EOL care for persons with AN who refuse life-sustaining measures, typically artificial nutrition. Palliative care outside of the EOL context and medical assistance in dying were not reviewed. As very little quantitative studies were identified, we qualitatively analyzed conceptual questions, ethical reasoning, legal aspects, stakeholder attitudes, practical aspects, stakeholder needs, and outcome. RESULTS: We identified 117 eligible publications from 1984 to 2023, mainly case reports (n=26 different cases) and ethical analyses. Conceptualizations of key terms such as terminality, futility, and decision-making capacity (DMC) in AN varied widely and were often value-laden and circular. Ethical reasoning centered on weighing the preservation of life versus quality of life in the context of uncertainty about DMC and likelihood of clinical remission. Studies on stakeholder attitudes reflected this challenge. In some cases, courts ruled against coerced life-sustaining measures and/or in favor of EOL care for persons with AN. While eligibility criteria were contested, recommendations for deliberating about and providing EOL care were consistent. We identified only one study on stakeholder needs and none on outcome. Case reports described quality of life under EOL care as good and death as the most frequent outcome but engagement in voluntary treatment and (partial) clinical remission in some. CONCLUSIONS: The debate around EOL care in AN needs consented, coherent terminology whose value base is reduced to a minimum and made transparent. While more empirical research into decision-making in AN and predictors of outcome might help reduce uncertainty, fundamental normative questions need to be addressed, for example regarding the ethico-legal significance of treatment refusals, the weighing of quantity versus quality of life and the appropriateness of diagnosis-based ethico-legal exceptionalism such as hard paternalism. More research is needed on outcome of and stakeholder needs in EOL care for persons with AN.

OBJECTIVE: The purpose of this study was to examine the association between weight gain and eating disorder (ED) symptoms among adults receiving treatment for atypical anorexia nervosa (AAN), to determine whether those who had a higher percent of expected body weight (%EBW) at discharge exhibited lower ED symptoms than those who gained less weight, and to compare this group to a matched sample of patients with anorexia nervosa (AN). METHOD: Participants were 96 adults receiving treatment at an ED treatment facility between December 2020 and May 2023. The Eating Disorder Examination-Questionnaire (EDE-Q) was completed at admission and discharge, and %EBW was obtained at admission and discharge. RESULTS: All EDE-Q subscale scores improved from admission to discharge for patients with AAN and patients with AN. Neither %EBW at discharge nor weight gain were associated with EDE-Q subscale scores for those with AAN. For patients with AN, %EBW at discharge and weight gain were associated with EDE-Q Restraint at discharge. CONCLUSIONS: Weight restoring to a higher level and gaining more weight were not associated with EDE-Q scores at discharge for AAN. Further research is needed to determine how weight restoration using intensive treatment settings affects remission and recovery in patients with AAN.

Gaudiani et al. (2022) presented terminal anorexia nervosa (T-AN) as a potential new specifier to the anorexia nervosa (AN) diagnosis, with criteria including (a) AN diagnosis, (b) age > 30 years, (c) previously participated in high-quality care, and (d) the clear, consistent determination by a patient with decision-making capacity that additional treatment would be futile, knowing death will result. This study's purpose was to empirically examine a subgroup of participants with AN who met the first three criteria of T-AN-and a smaller subset who also met a proxy index of the fourth criterion involving death (TD-AN)-and compare them to an adult "not terminal" anorexia nervosa (NT-AN) group and to a "not terminal" subset 30 years of age or older (NTO-AN). Patients at U.S. eating disorder treatment facilities (N = 782; T-AN: n = 51, TD-AN: n = 16, NT-AN: n = 731, NTO-AN: n = 133), all of whom met criteria for a current Diagnostic and Statistical Manual of Mental Disorders, 5th Edition diagnosis of AN, were compared regarding admission, discharge, and changes from admission to discharge on physiological indices (i.e., white blood cell counts, albumin levels, aspartate aminotransferase levels, and body mass index), as well as self-report measures (i.e., eating disorder, depression, anxiety, and obsessive-compulsive symptoms). In contrast to the tight syndromal symptom interconnections of, and inevitable spiral toward death expected for, a terminal diagnosis, results suggest substantial variability within the T-AN group and TD-AN subset, and an overall trend of improvement across physiological and self-report measures. This study thus provides some empirical evidence against the specification of the T-AN diagnosis. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

OBJECTIVE: Eating disorder (ED), depression, and anxiety symptoms at admission and discharge were compared, as were admission-to-discharge changes, for transgender and gender diverse (TGD), and cisgender adolescents receiving intensive treatment for EDs. METHOD: Participants were 44 TGD and 573 cisgender adolescents admitted to a treatment facility. Participants completed the Eating Disorder Examination Questionnaire (EDE-Q), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) at admission and discharge. RESULTS: Both groups had elevated EDE-Q scores at admission (TGD: M = 3.78, standard deviation [SD] = 1.70; cisgender: M = 3.33, SD = 1.74) that improved by discharge (TGD: M = 2.27, SD = 1.83, Cohen's d = .98; cisgender: M = 2.10, SD = 1.54, Cohen's d = .79); there were no differences in EDE-Q between groups at admission (p = .09; odds ratio [OR] = 1.18, 95% confidence interval [CI] [.98, 1.44]) or discharge (p = .48; OR = 1.07, 95% CI [.88, 1.30]). On admission, TGD adolescents had higher suicidality, measured by PHQ-9, item 9 (p < .001; OR = 1.94, 95% CI [1.51, 2.52]), and depression (p < .001; OR = 1.10, 95% CI [1.05, 1.16]) than cisgender participants. Severity decreased over treatment for all measures. Both groups showed similar improvement on suicidality (p = .93; OR = .98, 95% CI [.70,1.36]), depression (p = .42; OR = 1.02, 95% CI [.97, 1.07]), and anxiety (p = .14; OR = 1.05, 95% CI [.99, 1.12]). However, at discharge, suicidality (p = .02; OR = 1.40, 95% CI [1.04, 1.85]), depression (p < .01; OR = 1.06, 95% CI [1.02, 1.11]), and anxiety (p = .02; OR = 1.06, 95% CI [1.01, 1.12]) were higher for TGD adolescents than their cisgender peers. DISCUSSION: All participants had similar ED symptom severity and improvement. Depression, anxiety, and suicidality remained elevated for TGD adolescents compared to their cisgender peers at discharge, suggesting the need for targeted treatment. PUBLIC SIGNIFICANCE: Transgender and gender diverse (TGD) adolescents have increased risk of eating disorders (EDs); few studies examine how they respond to ED treatment. We examine treatment outcomes of TGD adolescents receiving ED treatment compared to their cisgender peers. We measured ED symptoms along with depression, anxiety, and suicidality at the beginning and end of treatment. While TGD adolescents showed similar improvement in ED symptoms, measures of depression, anxiety, and suicidality remained elevated at the time of discharge.

The COVID-19 pandemic has required a shift to telehealth services. However, not all patients are similarly satisfied with this shift, with some studies finding that midlife and older adults are less comfortable with telehealth. The current study examined patient satisfaction with a virtual intensive outpatient program (VIOP) for eating disorders (EDs) among 305 adults (ages 18-25, ages 26-39, and ages 40+), and compared adult satisfaction to satisfaction among children/adolescents (n = 33) receiving VIOP treatment between August 2020 and March 2022 from a large ED treatment facility. It was hypothesized that adults aged 40+ would report lower satisfaction than younger age groups. Patients completed several questions regarding satisfaction with treatment upon discharge, including a question about likelihood of recommending the program, which was used to calculate a Net Promoter Score (NPS). The NPS was 33.3 for children/adolescents, 33.3 for 18-25 year-olds, 57.7 for 26-39 year-olds, and 30.9 for the 40+ year age group. NPS of 31-50 = quality services; 51-70 = excellent customer experiences. Satisfaction was high, with no statistically significant differences between age groups after Bonferroni correction. The current study adds to the limited literature on the treatment experiences of midlife adults with EDs.
RESUMEN
The etiology of anorexia nervosa (AN) remains to be fully elucidated, and current theories also fail to account for the direct effect of starvation on the health of the organs and tissues, specifically the connective tissue present in most organs of the body. Individuals with hereditary disorders of connective tissue manifest with clinical symptoms that overlap with AN, as the abnormal connective tissue also contributes to many of the other extra-articular manifestations of these hereditary disorders. This article hypothesizes that a similar pathophysiology may also contribute to the clinical presentation of AN. Therefore, a better understanding is needed to elucidate: (1) the relationship between abnormal connective tissue and AN, (2) the impact of starvation toward the development of abnormal connective tissue and how this manifests clinically, (3) the etiology of autonomic nervous system changes contributing to the dysautonomia in AN, and (4) how the sensory signals sent from potentially abnormal connective tissue to the central nervous system impact interoception in AN. A conceptual model incorporating abnormal connective tissue is provided. PUBLIC SIGNIFICANCE: The etiology of AN remains poorly understood and current theories fail to account for the direct impact of starvation on the health of the organs and tissues of the body. There is significant clinical overlap between AN and hereditary connective tissue disorders. This paper attempts to provide a new conceptual model for AN in which abnormal connective tissue contributes to the underlying pathogenesis.

BACKGROUND: People with severe eating and feeding disorders regularly require hospitalization due to complications inherent to their disease, though formal training regarding this care is limited. METHODS: This retrospective study included 545 patients with severe anorexia nervosa (AN) or avoidant restrictive food intake disorder hospitalized in a medical stabilization unit between 2018 and 2021. Biometrics were obtained throughout hospitalization. Nutrition was increased until patients were gaining 0.2 kg/day. RESULTS: Average admission body mass index was 13 kg/m2 with diagnoses of 46% AN-R (restricting), 39% AN-BP (binge-purge), and 15% avoidant restrictive food intake disorder. Average daily Kcals by discharge were 3343 for females and 3962 for males; 26% required nasogastric feeding. Hypoglycemia was common until day 7, correlated with elevated liver function tests and low prealbumin. Liver function tests were abnormal in 31% of patients. Refeeding hypophosphatemia developed in 26% of patients starting day 2 and was associated with lower body mass index. Hypokalemia appeared on admission among 39%, twice as common in patients diagnosed with AN-BP. Initial electrocardiograms were abnormal in 50% of patients, usually sinus bradycardia. Average QTc was normal, but only 14% prolonged. Bone density testing revealed 70% osteoporosis. History of suicide attempts were present in 19%, while 76% and 50% presented with anxiety and depressive disorders, respectively. CONCLUSIONS: Given the inextricability of medical complications from severe eating and feeding disorders, familiarity among consult-liaison psychiatrists with the prevalence of frequently observed abnormal findings can inform consultation, prevent adverse events, prevent unnecessary intervention, and facilitate weight restoration and medical stabilization.
RESUMEN
OBJECTIVE: Anorexia nervosa (AN) is a serious illness with a high mortality rate and multiple physiological complications. The vague definition of atypical AN allows for subjective interpretation. This retrospective study aimed to focus future research on the operational definition of atypical AN by examining four factors associated with atypical AN at admission to higher level of care treatment. METHODS: Adults with atypical AN (n = 69) were examined within sample analyses among four groups: (1) >10% versus ≤10% weight loss; (2) weight loss within the previous 3 months versus >3 months; (3) engaging in purging behaviors versus absence of purging behaviors; and (4) endorsing versus not endorsing significant cognitive aspects of AN. RESULTS: Patients with atypical AN endorsed elevated ED cognitions on the Eating Disorder Examination-Questionnaire and depressive symptoms; a lack of association was found between weight loss severity and weight loss time frame with depressive symptoms, eating concern, and restraint. Purging behavior was associated with a higher expected body weight percentage (%EBW) and dietary restraint, while greater AN cognitions were associated with a higher EBW and weight loss percentage. Few patients demonstrated bradycardia, hypophosphatemia, or amenorrhea. DISCUSSION: This study demonstrated the severity of ED cognitions and depressive symptoms in this atypical AN sample and provided directions for future studies in the nosology of atypical AN. It may be important to distinguish between individuals with atypical AN who are purging and those who are not. Atypical AN was associated with a low frequency of physiological disturbances. PUBLIC SIGNIFICANCE: This study provides further clarification regarding the operational definition of atypical AN; currently, a constellation of symptoms under Other Specified Feeding or Eating Disorders. This study was consistent with previous research in reporting severe eating disorder cognitions in adults with atypical AN, and noted the potential importance of distinguishing a purging distinction. A minority of patients in this study had physiological impairments.

OBJECTIVE: The physical complications of atypical anorexia nervosa remain understudied, with most studies completed in adolescents. This study seeks to examine the impact of various weight measures as predictors of medical instability in a large cohort of adult eating disorder patients. METHODS: In this retrospective cohort study, the impact of admission body mass index (BMI), weight suppression, and recent weight loss (the rate of weight loss within the last 12 months) toward the development of medical complications of malnutrition were examined. Multivariable logistic regression assessed the association of binary clinical outcomes of interest with recent weight loss and weight suppression (adjusting for age, admission BMI, gender, and purging behaviors). Odds ratios (OR) and 99% confidence intervals were reported. RESULTS: Greater recent weight loss increased the odds of developing low prealbumin and reduced hand grip strength. A greater weight suppression was associated with increased likelihood of amenorrhea, reduced systolic blood pressure, nadir hemoglobin, and weekly weight gain upon nutritional rehabilitation. Lower admission BMI was predictive of all the medical outcomes examined, with the exception of bradycardia, and was generally the strongest predictor based on standardized coefficients. DISCUSSION: Recent weight loss and weight suppression are predictive of some of the physiologic changes of malnutrition, although low BMI is seemingly the greatest predictor for the development of these complications. These findings suggest that some patients with aggressive weight suppression and/or acute weight loss would benefit from medical stabilization, although this needs to be further defined. PUBLIC SIGNIFICANCE: In adults, low BMI seems to be a better predictor of medical complications than weight suppression or aggressive recent weight loss. In adults, greater weight suppression is associated with increased likelihood of amenorrhea, reduced systolic blood pressure, nadir hemoglobin, and weight gain upon nutritional rehabilitation.

The current study assessed treatment outcome for 99 adult admissions to a residential program specifically designed for binge eating spectrum disorders (BESD). Participants completed self-report measures at admission, discharge, and 12-month follow-up and were asked to complete blood draws at admission and follow-up. Primary outcomes were eating behaviors; secondary outcomes included comorbid symptoms and physiological variables. Eating behaviors improved significantly from admission to follow-up, as did most comorbid symptoms and quality of life, despite no change in body mass index. Some variables displayed a curvilinear relationship, with some worsening of symptoms from discharge to follow-up, although scores at follow-up remained well below admission values. Participation in the treatment program was associated with reduced problematic eating and comorbid symptoms and increased quality of life up to one year after discharge. Findings from this study may encourage the development of similar residential treatment programs for BESD for those who have not responded to outpatient care or mixed milieu settings, and may prompt randomized studies testing similar treatments versus usual care.

OBJECTIVE: Although eating disorders (EDs) occur throughout the lifespan, little research has been conducted with midlife/older adults, particularly those in higher levels of care (HLOC). The current study examined outcomes among 2009 patients with EDs receiving HLOC treatment at a large multisite facility between January 2020 and June 2022, across different age groups (ages <18, 18-25, 26-39 and ≥40). It was hypothesised that patients aged 40+ would exhibit less improvement on measures of ED psychopathology and depression than other age groups. METHOD: Participants completed the eating disorder examination-questionnaire (EDE-Q) and the patient health questionnaire-9 (PHQ-9) at admission and discharge. RESULTS: Changes for all outcomes from admission to discharge were statistically significant at p < 0.001 across all age groups. Changes in the EDE-Q Restraint subscale were significantly less in patients ages 26-39 than in patients ages 18-25 (p < 0.01). Changes in PHQ-9 were significantly greater in patients ages 40+ than patients ages 18-25 (p = 0.03). CONCLUSIONS: Contrary to hypotheses, patients ages 40+ did not show worse outcomes than younger patients, and showed greater improvements in depression than young adults. The therapeutic needs of midlife/older adults with EDs may be favourably met by a HLOC regimen as described in this study.

Most research on avoidant/restrictive food intake disorder (ARFID) has been with children and adolescents, while the limited research on adults with ARFID has been in the domain of outpatient treatment. This descriptive study sought to explore psychological characteristics (N = 45; measured with self-report questionnaires) and physiological characteristics (N = 66; e.g. vital signs, bloodwork) at admission for 66 adults with ARFID seeking residential and inpatient levels of care. While adults with ARFID presented with significant food restriction as well as mild depressive symptoms, high anxiety symptoms, and impaired quality of life, patients presented with mostly normal physiology, except for low bone density, and trivial abnormalities in serum creatinine and hepatic enzymes. Patients in this sample were most likely to endorse fear of aversive consequences, especially those for whom ARFID symptoms had first arisen in adulthood. These results note the psychological impairment and relative physiological normalcy of treatment-seeking adults with ARFID at the outset of residential and inpatient treatment, identifying future treatment and outcome research priorities in this understudied population.

Establishing normative data for questionnaires is essential for the accurate interpretation of scores, given that these norms can vary according to different subpopulations and treatment contexts. The purpose of this study was to establish norms for the Eating Disorder Examination-Questionnaire (EDE-Q) among adults receiving higher levels of care (HLOCs) for the treatment of eating disorders. Participants were 2,283 people receiving treatment at the inpatient, residential, partial hospitalization, or intensive outpatient levels of care. The EDE-Q was completed at admission. Patients with anorexia nervosa-restricting subtype (AN-R) had the lowest EDE-Q Global scores when compared with all other eating disorder diagnoses. When compared with intensive outpatient care, only those in residential treatment had higher EDE-Q Global scores. This study is among the first to describe norms for the EDE-Q in a large sample of adults receiving various HLOCs. Programs utilizing the EDE-Q to assess treatment outcomes can use these findings to aid people in interpreting their scores.
RESUMEN
BACKGROUND: Refeeding hypophosphatemia (RH) is a common complication of nutritional restoration in malnourished individuals, yet clear risk stratification remains elusive. Individuals with anorexia nervosa (AN) and avoidant/restrictive food intake disorder (ARFID) may be deficient in vitamin D, an important component of dietary phosphorus absorption in the gut. The relationship between vitamin D and RH in AN and ARFID is unknown. Therefore, the aims of this study were to (1) report rates of low serum 25-hydroxy vitamin D and RH in AN and ARFID; (2) describe associations between phosphorus and variables associated with RH identified in extant literature; (3) examine the relationship between 25-hydroxy vitamin D and RH and (4) investigate moderation by vitamin D between variables of interest and phosphorus level. METHOD: Analyses included retrospective chart review of 307 individuals admitted to the ACUTE Center for Eating Disorders and Severe Malnutrition with a diagnosis of AN or ARFID. Variables of interest included admission laboratory values (vitamin D level, comprehensive metabolic panel, hemoglobin, point-of-care blood glucose), anthropometric measures (weight, body mass index [BMI], % ideal body weight [IBW]), age, duration of illness, length of stay, feeding method, and serum phosphorus nadir. Pearson and Spearman rank correlation, one-way ANOVA, and regression analyses were used to determine the relationship between variables and serum phosphorus. RESULTS: Over 1/3 of the sample (35.3%) had serum phosphorus levels ≤ 2.9 mg/dL. There were no significant differences between groups in phosphorus nadir (p = .17, η2 = 0.12) or hypophosphatemia (p = .16, Ïc = 0.11). Thirty-five (35%) of individuals with ARFID were either deficient or insufficient in vitamin D, compared to 29% of individuals with AN. Individuals with AN had significantly higher mean vitamin D levels compared to those with ARFID (p = .03; η2 = 0.015). Nadir phosphorus showed a positive association with weight, BMI, %IBW, potassium, and calcium on admission, and a negative association with length of stay, hemoglobin, and total number of tube-fed days. Higher levels of 25-hydroxy vitamin D moderated the relationship between serum phosphorus nadir and weight on admission (p = .0004). CONCLUSION: Individuals diagnosed with ARFID are as nutritionally fragile as those with AN regarding vitamin D and RH. The negative feedback loop involving vitamin D that maintains phosphorus homeostasis may play a role in the development of RH in AN and ARFID.
Refeeding hypophosphatemia (RH) is a common and potentially serious complication of nutrition restoration, yet its risk is not fully understood. Vitamin D is an important part of phosphorus absorption in the gut. We examined 25-hydroxy vitamin D levels on admission and the relationship with RH in individuals with avoidant/restrictive food intake disorder (ARFID) and anorexia nervosa (AN). Results showed individuals with ARFID had significantly lower vitamin D levels than individuals with restrictive type AN, but not individuals with binge/purge type AN. Additionally, analyses showed that higher levels of vitamin D may play a role in the association between RH and weight on admission. Better understanding of RH risk may improve care.
RESUMEN
BACKGROUND: Acute gastric dilatation can develop in patients with anorexia nervosa who are being refed to achieve weight restoration. If unrecognized, this condition is associated with significant morbidity and mortality. Patients with acute gastric dilatation usually have abdominal pain, nausea, and vomiting. Abdominal imaging confirms the diagnosis. This study aims to identify risk factors associated with the development of acute gastric dilatation in patients with severe restrictive eating disorders in order to hasten diagnosis and guide treatment. This study also aims to define the clinical outcomes of patients with acute gastric dilatation. METHODS: In this retrospective case series, 15 patients with a restrictive eating disorder were studied. Multiple variables were assessed for significant correlation with stomach size. RESULTS: 15 patients with a restrictive eating disorder were identified as being diagnosed with acute gastric dilatation through chart review during the study period. The average dilated stomach size was 20.5 cm. There was no significant correlation of stomach size with any of the following: % ideal body weight on day of admission, % ideal body weight on day of imaging study, rate of weight gain (kg per week), or duration of illness. Serum levels of sodium, potassium, phosphorus, magnesium, calcium, bicarbonate, blood urea nitrogen, glucose, albumin, and hematocrit on the day of imaging, did not correlate with stomach size. All patients were treated with conservative management. None of the patients required surgical intervention or progressed to gastric necrosis or perforation, and there were no recurrences of the acute gastric dilatation. CONCLUSIONS: There are no specific risk factors significantly associated with the development of acute gastric dilatation in patients with severe restrictive eating disorders. Clinicians should maintain a high index of suspicion for this condition when patients are experiencing abdominal pain, nausea, or vomiting. When promptly diagnosed and treated, outcomes are good. If diagnosis is delayed, the outcome can be dire.
The mainstay of treatment of patients with severe restrictive eating disorders is initiation of nutrition to gain weight. One potential complication when patients are started on nutrition is the development of a massively enlarged stomach, also called acute gastric dilatation. If a patient's care provider does not recognize the development of acute gastric dilatation, it can lead to serious problems, including death. Patients with this condition usually have abdominal pain, nausea, and vomiting. These are common symptoms in patients with anorexia nervosa and are often dismissed. Identifying risk factors associated with developing acute gastric dilatation could help providers recognize this condition and promptly start treatment. This study sought to identify risk factors associated with developing acute gastric dilatation in patients with severe restrictive eating disorders. Several variables, including patient age, duration of illness, body mass index, %ideal body weight, laboratory values, medications, type of nutrition, and rate of weight gain were analyzed. This study found that there are no specific risk factors significantly associated with development of acute gastric dilatation in patients with severe restrictive eating disorders being initiated on nutrition. Therefore, providers need to listen to their patients, evaluate symptoms, and have a high index of suspicion for underlying acute gastric dilatation.
RESUMEN
BACKGROUND: Anorexia nervosa (AN) is associated with left ventricular (LV) atrophy and unexplained sudden death. Myocardial mechanics have not been well studied in adults with AN. Whether LV mass or illness duration, markers of AN severity, correlate with abnormal strain imaging is unknown. METHODS: We performed a prospective study among patients hospitalized with severe AN (n = 29) [body mass index (BMI) < 14.5 kg/m2] and sex/age-matched controls (n = 16) (BMI > 18.5 kg/m2). LV ejection fraction (LVEF) was calculated via modified-biplane method and LV mass was derived using the truncated ellipsoid formula. Apical 2-, 3-, and 4-chamber images were used to generate regional strain mapping and global longitudinal strain (GLS). N-terminal brain natriuretic peptide (NT-proBNP) levels were measured and linear regression was used to determine independent predictors of strain. RESULTS: Mean LVEF did not differ (65% ± 6.0 vs. 62% ± 4.4, p = 0.06), but LV mass was substantially reduced (61.6 ± 16.8 vs. 97.6 ± 19.1 g, p < .0001). GLS was similar (- 20.6 ± 3.8 vs. - 20.9 ± 2.8, p = 0.82), however, the basal strain was worse (-18.7 ± 4.8 vs. -21.9 ± 4.1, p = 0.03). Lower LV mass was associated with worsening GLS (r = - 0.40, p = 0.003), but not among controls (p = 0.89). Median (IQR) NT-proBNP (pg/ml) was higher in patients with AN [141 (59-257) vs. 35.5 (21-56.5) p = 0.0007]. Both increasing NT-proBNP and illness duration were associated with worsening strain patterns in AN (both p = .001). CONCLUSIONS: While LVEF and GLS did not differ, regional strain variation was noted among patients with AN. Elevated NT-proBNP may reflect increased wall tension from LV atrophy. Whether strain heterogeneity can identify patients with AN, at risk for sudden death, requires further study.
RESUMEN
The Eating Disorder Examination-Questionnaire (EDE-Q) is a widely used self-report measure of eating pathology. Despite widespread use, investigations of its factor structure have proved inconclusive and rarely supported the "original" interpretation. The current study evaluates several proposed factor solutions of the EDE-Q using latent variable analysis in a sample of adult women with anorexia nervosa (AN). A total of 804 patients from a specialist treatment center in the United States participated in the study. Confirmatory factor analysis was conducted on 22 EDE-Q items assessing attitudinal features of eating pathology. Findings suggested that three full-item versions (none of which was the "original" interpretation) fit the data adequately, with a brief, seven-item version showing excellent fit. The study is one of the first to examine this within a sample of women with AN and provides an empirical foundation for how best to use the EDE-Q among clinical and research participants with AN. Findings suggest that the "original" factor structure lacks structural validity in women with AN. Its use should generally be discouraged, and future work on screening and treatment outcomes might consider the EDE-Q7.
RESUMEN
OBJECTIVE: Involuntary treatment for anorexia nervosa (AN) is sometimes necessary and lifesaving but can be experienced negatively by some individuals. The purpose of this qualitative study was to better understand participants' perceptions about their experience with involuntary treatment for AN. METHOD: Thirty adult participants, who had been treated involuntarily for AN in the past, completed self-report measures and qualitative interviews. Interview transcripts were coded using thematic analysis. RESULTS: Three themes were identified: (1) mixed perceptions about involuntary treatment, (2) the impact of involuntary treatment on external factors, including relationships, education, and employment, and (3) lessons learned from the experience. Participants who endorsed a positive shift in perspective regarding the need for involuntary treatment also reported favorable changes in their eating disorder recovery, whereas individuals whose perspective about their involuntary treatment remained negative, showed no changes in their recovery post-treatment. CONCLUSIONS: Involuntary treatment for AN was recognized, in retrospect, as being beneficial by individuals with AN who were doing well, but individuals who continued to struggle with their eating disorder reported negative consequences.

People with anorexia nervosa (AN) tend to shy away from engaging in typical primary care provider relationships in order to avoid detection. Therefore, they may seek care for their medical concerns through a local emergency department (ED). Inherently, AN is associated with a litany of medical complications, which become more prevalent as the severity of their eating disorder increases. Notwithstanding the typical young age at the onset of AN, no body system is immune to these medical complications. Thus, ED providers may need to pursue a medical diagnosis in order to explain presenting symptoms in people with AN. In addition to the medical issues, AN is also a serious mental illness with high mortality rates, including deaths by suicide. Therefore, ED providers also need to be familiar with relevant mental health issues for these people.
People with anorexia nervosa frequent emergency departments to obtain their medical care. It is thus important for emergency department personnel to be familiar with this increasingly common and serious disorder. As opposed to most other mental illnesses, anorexia nervosa is associated with many dangerous medical complications, which become more problematic as the malnutrition and weight loss become more severe. All body systems are adversely affected. The mortality rate of anorexia nervosa is the second highest of all mental disorders, with medical complications and suicide being the top two causes of death. Mandated medical care may occasionally be required to obtain ongoing treatment for people with anorexia nervosa when they present to the emergency department with severe malnutrition and other emergent complications.
