BACKGROUND
Anorexia Nervosa (AN) poses significant therapeutic challenges, especially in cases meeting the criteria for Severe and Enduring Anorexia Nervosa (SE-AN). This subset of AN is associated with severe medical complications, frequent use of services, and the highest mortality rate among psychiatric disorders.
CASE PRESENTATION
In the present case series, 14 patients were selected from those currently or previously taken care of at the Eating Disorders Outpatients Unit of the Maggiore Hospital in Bologna between January 2012 and May 2023. This case series focuses on the effects of the disease, the treatment compliance, and the description of those variables that could help understand the great complexity of the disorder.
CONCLUSION
This case series highlights the relevant issue of resistance to treatment, as well as medical and psychological complications that mark the life course of SE-AN patients. The chronicity of these disorders is determined by the overlapping of the disorder's ego-syntonic nature, the health system's difficulty in recognizing the problem in its early stages, and the presence of occupational and social impairment.

BACKGROUND
The aim of this systematic review is to critically summarize current literature concerning ethical and legal issues related compulsory treatment (CT) in patients with anorexia nervosa (AN).
SUBJECTS AND METHODS
Relevant articles were identified following the PRISMA guidelines after performing title/abstract screening and full text screening. We built the search string using the following terms: "coercion", "compulsory/involuntary treatment", "eating disorders", "anorexia nervosa", "mental capacity", "ethical/legal issues". Research was conducted on original articles published from any time until June 2023.
RESULTS
Out of 302 articles retrieved, seven were included for the analysis, including five studies on mental health practitioners, and two on hospital records. The results show that mental health practitioners a) favor the use of CT, but the support is weaker in AN vs other psychiatric conditions (i.e., schizophrenia or depression); b) support of mental capacity is controversial and some variability was found between different categories of psychiatrists; in particular, both ED-treating and CT experienced mental health practitioners support higher use of CT and lack of capacity of AN patients vs. general psychiatrists; c) use of CT is more supported in the early vs. chronic AN, when chances of success are lower. The analysis of hospital records identified 1) comorbidities, previous admissions and current health risk as CT predictors in 96 Australian patients; 2) family conflicts association with longer hospitalizations in 70 UK patients.
CONCLUSION
CT is usually intended for patients with AN at the onset of disease, mainly to prevent risk of death and self-injury. However, there is some variability in the attitude to perform CT among psychiatrists working in different setting, also related to the concept of mental capacity. There are also cross-national variabilities regarding CT. We can conclude that forcing patients to treatment is a conceivable option, but the balance between protection respect for patient's autonomy should be evaluated on individual bases.

OBJECTIVE
Body mass index (BMI) is the primary criterion differentiating anorexia nervosa (AN) and atypical anorexia nervosa despite prior literature indicating few differences between disorders. Machine learning (ML) classification provides us an efficient means of accurately distinguishing between two meaningful classes given any number of features. The aim of the present study was to determine if ML algorithms can accurately distinguish AN and atypical AN given an ensemble of features excluding BMI, and if not, if the inclusion of BMI enables ML to accurately classify between the two.
METHODS
Using an aggregate sample from seven studies consisting of individuals with AN and atypical AN who completed baseline questionnaires (N = 448), we used logistic regression, decision tree, and random forest ML classification models each trained on two datasets, one containing demographic, eating disorder, and comorbid features without BMI, and one retaining all features and BMI.
RESULTS
Model performance for all algorithms trained with BMI as a feature was deemed acceptable (mean accuracy = 74.98%, mean area under the receiving operating characteristics curve [AUC] = 74.75%), whereas model performance diminished without BMI (mean accuracy = 59.37%, mean AUC = 59.98%).
DISCUSSION
Model performance was acceptable, but not strong, if BMI was included as a feature; no other features meaningfully improved classification. When BMI was excluded, ML algorithms performed poorly at classifying cases of AN and atypical AN when considering other demographic and clinical characteristics. Results suggest a reconceptualization of atypical AN should be considered.
PUBLIC SIGNIFICANCE
There is a growing debate about the differences between anorexia nervosa and atypical anorexia nervosa as their diagnostic differentiation relies on BMI despite being similar otherwise. We aimed to see if machine learning could distinguish between the two disorders and found accurate classification only if BMI was used as a feature. This finding calls into question the need to differentiate between the two disorders.

Review
Multifamily therapy (MFT) for adolescent eating disorders (ED) is anchored in systemic theory and family therapy, but two conceptual and practical paths have emerged from this common framework. The first one, called ED-focused MFT, is centered on behavioral change and weight gain in the early stages of treatment, while the second, known as relationship-focused MFT, is less directly focused on symptom improvement and more on family changes. Compared to ED-focused MFT, validation of more relationship-focused MFT models has been lagging behind although they are frequently implemented and practiced in Europe. The purpose of this article is to give more visibility to existing relationship-focused MFT models by presenting an integrative, yet predominantly family-oriented MFT program developed for adolescent anorexia nervosa (AN) (12 to 18 years) on the ED unit of a large pediatric hospital in France. After presenting the history and development of this relationship-focused MFT program, including the challenges it encountered and its evaluation, we describe its rationale and objectives, then outline its course and content, giving illustrations of techniques and activities for each of the five phases of the program. Finally, we review the current status of this model, its advantages and limitations, and provide a critical appraisal of existing evidence and recommended future research directions.

Review
OBJECTIVE
The gut microbiota is implicated in several symptoms and biological pathways relevant to anorexia nervosa (AN). Investigations into the role of the gut microbiota in AN are growing, with a specific interest in the changes that occur in response to treatment. Findings suggest that microbial species may be associated with some of the symptoms common in AN, such as depression and gastrointestinal disturbances (GID). Therefore, researchers believe the gut microbiota may have therapeutic relevance. Whilst research in this field is rapidly expanding, the unique considerations relevant to conducting gut microbiota research in individuals with AN must be addressed.
METHOD
We provide an overview of the published literature investigating the relationship between the gut microbiota and symptoms and behaviors present in AN, discuss important challenges in gut microbiota research, and offer recommendations for addressing these. We conclude by summarizing research design priorities for the field to move forward.
RESULTS
Several ways exist to reduce participant burden and accommodate challenges when researching the gut microbiota in individuals with AN.
DISCUSSION
Recommendations from this article are foreseen to encourage scientific rigor and thoughtful protocol planning for microbiota research in AN, including ways to reduce participant burden. Employing such methods will contribute to a better understanding of the role of the gut microbiota in AN pathophysiology and treatment.
PUBLIC SIGNIFICANCE
The field of gut microbiota research is rapidly expanding, including the role of the gut microbiota in anorexia nervosa. Thoughtful planning of future research will ensure appropriate data collection for meaningful interpretation while providing a positive experience for the participant. We present current challenges, recommendations for research design and priorities to facilitate the advancement of research in this field.

OBJECTIVE
While menstrual irregularities are acknowledged in restrictive-type eating disorders (EDs), the menstrual characteristics specific to atypical anorexia nervosa (AAN) remain inadequately defined. This study aims to compare the menstrual features of anorexia nervosa (AN) and AAN.
METHOD
Adolescents diagnosed with AN or AAN who exhibited secondary amenorrhoea at presentation and had their menstrual cycles restored during follow-up were eligible for this study. Clinical and menstrual data at admission and during follow-up were obtained from patient files, and compared between the AN and AAN cohorts.
RESULTS
The study included a total of 77 patients (38 with AN and 39 with AAN). The extent of weight loss and the disease duration until the onset of amenorrhoea were comparable in the two groups. However, the duration of illness and the time since the last menstrual period at admission were shorter in the AAN group. Moreover, amenorrhoea manifested at a higher body mass index, and the return of menses occurred more rapidly with less weight gain in the AAN group after the onset of clinical follow-up. Additionally, the AAN group exhibited a shorter overall duration of amenorrhoea.
CONCLUSIONS
This study highlights the significance of recognising amenorrhoea in restrictive disorders, even when individuals maintain a normal weight. The faster return of menstrual cycles and shorter duration of amenorrhoea observed in adolescents with AAN emphasise the significance of early diagnosis and prompt initiation of treatment. Regardless of the patient's presenting complaint and weight status, obtaining a comprehensive ED history is essential when addressing concerns regarding amenorrhoea or menstrual irregularities.

Review
UNLABELLED
Cardiac complications are a major concern in patients with anorexia nervosa (AN) which contribute to morbidity and mortality. However, limited information exists regarding risk factors for the development of these complications. Our objective was to investigate the prevalence and associated risk factors of cardiac involvement among children and adolescents with AN admitted to a tertiary pediatric hospital. We collected demographic, clinical, and laboratory data from individuals with AN hospitalized between 2011 and 2020 in Schneider Children's Medical Center in Israel. Diagnosis was based on established criteria (DSM-5). Patients with other co-morbidities were excluded. Cardiac investigations included electrocardiograms (ECG) and echocardiograms. We conducted correlation tests between cardiac findings and clinical and laboratory indicators. A total of 403 AN patients (81.4% were females) with a median age of 15 ± 2 years were included in the study. Sinus bradycardia was the most common abnormality, observed in 155 (38%) participants. Echocardiogram was performed in 170 (42.2%) patients, of whom 37 (22%) demonstrated mild cardiac aberrations. Among those aberrations, 94.6% could be attributed to the current metabolic state, including pericardial effusion (15.3%) and valve dysfunction (8.8%). Systolic or diastolic cardiac dysfunction, tachyarrhythmias, or conduction disorders were not observed. Patients with new echocardiographic aberration had significantly lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension was higher in this group.
CONCLUSIONS
The prevalence of cardiac involvement, except for sinus bradycardia, was notably low in our cohort. The presence of cardiac aberrations is correlated with several clinical variables: lower body mass index (BMI) and the presence of amenorrhea and hypotension at admission. Patients presenting with these variables may be at high risk for cardiac findings per echocardiography. Dividing the patients into high and low risk groups may enable targeted evaluation, while avoiding unnecessary cardiac investigations in low-risk patients.
WHAT IS KNOWN
• Cardiac involvement in anorexia nervosa (AN) patients is a major concern, which contributes to morbidity and mortality. • It is unknown which patients are prone to develop this complication.
WHAT IS NEW
• Cardiac complications in our cohort are less frequent compared to previous studies, and it is correlated with lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension.

OBJECTIVE
Atypical anorexia nervosa (AN) has been increasingly identified in the community and in clinical settings. Initial studies indicate that psychological symptoms are similar or more severe among patients with atypical AN, as compared with AN. This study examined whether eating behavior differed among patients with AN (n = 98), patients with atypical AN (n = 18), and healthy controls (HC, n = 75).
METHOD
Adults and adolescents chose what to eat from a standardized, laboratory-based multi-item meal. Total intake, macronutrient composition, diet variety, and energy density were compared between groups.
RESULTS
Both AN and atypical AN severely restricted caloric intake as compared with HC (431 ± 396 kcal and 340 ± 338 kcal vs. 879 ± 350 kcal, F = 35.4, p < .001). Individuals with AN and atypical AN did not differ in the mean intake of total calories or percentage of calories from fat (15.2 ± 25.2% vs. 11.5 ± 16.9%).
DISCUSSION
This study demonstrates that individuals with atypical AN are at least as restrictive in their food intake as individuals with AN, and the restriction of dietary fat is particularly notable. Examination of eating behavior in a larger sample would be useful to replicate these findings. The current study highlights the need to understand maladaptive eating behavior in atypical AN in order to develop appropriate treatment recommendations.
PUBLIC SIGNIFICANCE
Atypical anorexia nervosa is emerging as a prevalent eating disorder in community and clinical populations. The findings that patients with atypical anorexia nervosa limit calorie and fat intake in a pattern similar to that of patients with anorexia nervosa highlights the need for research to identify appropriate treatment strategies for normalization of eating patterns.

Review
Eating disorders continue to be a major public health issue and important cause of morbidity and premature mortality, particularly for young people. Yet in a concerning dialectic, this occurs in the context of an epidemic of obesity which, with its medical complications, constitutes another vexing public health challenge. While it is not an eating disorder per se obesity is often comorbid with eating disorders. Effective treatment for both eating disorders and obesity has proven to be elusive and in the search for novel therapeutic interventions, the prosocial, anxiolytic, brain plasticity and metabolic effects of oxytocin (OT) have been examined from this perspective. The availability of intranasal oxytocin (IN-OT) has led to a number of interventional treatment studies in anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), their atypical and subclinical forms and in medical and psychiatric conditions co-occurring or comorbid with these, obesity with BED would be included here. The aim of this mini review is to collate recent findings on OT as a novel therapeutic intervention in eating disorders and obesity and to identify and address some of the knowledge gaps in the use of IN-OT. The wider clinical perspective utilised here might better address some of the gaps and identify future directions of research. Clearly much remains to be done for OT to fulfil its therapeutic promise in eating disorders. OT might yet be of therapeutic promise and will be appreciated where treatment advances have been hard to come by and prevention challenging for these disorders.

OBJECTIVE
Literature comparing "atypical" anorexia nervosa (atypical AN) and anorexia nervosa (AN) suggests these diagnoses share significant similarities in eating disorder (ED) pathology and psychiatric comorbidities. This study evaluated potential differences in ED pathology, psychiatric comorbidity, associated mechanisms (i.e., ED fears and perfectionism), and demographic factors (i.e., ethnicity and age) between individuals with atypical AN and AN.
METHOD
Data from seven protocols were combined for a total 464 individuals diagnosed with atypical AN (n = 215) or AN (n = 249). Between-group differences in ED severity and behaviors, psychiatric comorbidities, ED fears, perfectionism, and demographic factors were assessed using t-tests, Wilcoxon rank-sum tests, and Fisher's exact test.
RESULTS
Participants with atypical AN reported higher levels of overvaluation of weight and shape than those with AN. Participants with AN scored higher on food-related fears (anxiety about eating, food avoidance behaviors, and feared concerns) and fears of social eating, as well as obsessive-compulsive symptoms. Participants with AN were more likely to identify as Asian or Pacific Islander. No other statistically significant differences were found between groups for overall ED severity, ED behaviors, psychiatric comorbidities, general ED fears, perfectionism, or demographic factors.
DISCUSSION
Overall, results support previous literature indicating limited differences between individuals with atypical AN and AN, though individuals with atypical AN reported more overvaluation of weight and shape and those with AN reported higher food and social eating fears and obsessive-compulsive symptoms. Relatively few overall differences between atypical AN and AN highlight the importance of exploring dimensional conceptualizations of AN as an alternative to the current categorical conceptualization.
PUBLIC SIGNIFICANCE
This study assessed differences among individuals with atypical anorexia nervosa and anorexia nervosa in eating disorder severity and behaviors, comorbid psychiatric diagnoses, associated mechanisms, and demographic factors. Few differences emerged, though participants with atypical anorexia nervosa reported more overvaluation of weight and shape, while those with anorexia nervosa reported more food and social eating fears and higher obsessive-compulsive symptoms. Results support exploration of these diagnoses as a spectrum disorder.
