Abstract
Anorexia nervosa (AN) is a multifactorial disorder. A possible role of the social network and the gut microbiota in pathogenesis has been added. Exogenous shocks such as the COVID19 pandemic have had a negative impact on patients with AN. The potential medical and nutritional impact of malnutrition and/or compensatory behaviors gives rise to a complex disease with a wide range of severity, the management of which requires a multidisciplinary team with a high level of subject matter expertise. Coordination between levels of care is necessary as well as understanding how to transition the patient from pediatric to adult care is essential. A proper clinical evaluation can detect possible complications, as well as establish the organic risk of the patient. This allows caregivers to tailor the medical-nutritional treatment for each patient. Reestablishing adequate nutritional behaviors is a fundamental pillar of treatment in AN. The design of a personalized nutritional treatment and education program is necessary for this purpose. Depending on the clinical severity, artificial nutrition may be necessary. Although the decision regarding the level of care necessary at diagnosis or during follow-up depends on a number of factors (awareness of the disease, medical stability, complications, suicidal risk, outpatient treatment failure, psychosocial context, etc.), outpatient treatment is the most frequent and most preferred choice. However, more intensive care (total or partial hospitalization) may be necessary in certain cases. In severely malnourished patients, the appearance of refeeding syndrome should be prevented during renourishment. The presence of AN in certain situations (pregnancy, vegetarianism, type 1 diabetes mellitus) requires specific care. Physical activity in these patients must also be addressed correctly.

Abstract
OBJECTIVES Co-occurrence of Anorexia Nervosa (AN) and borderline personality disorder (BPD) is frequent (8%-40%) and associated with specificities that impact the treatment process. Lifetime history of suicide attempt (HAS), substance use disorder (SUD) and the binge-purging subtype (B-P) might be good markers of such comorbidity. We made the hypothesis that in patients with AN, the presence of HAS, SUD and B-P have sufficient predictive power to efficiently detect an associated BPD comorbidity. METHODS After a case report analysis on a pilot sample of 119 patients with AN, we performed a cross-sectional analysis on a confirmatory sample of 84 patients with AN in a single center specialized in eating disorders systematically assessing HAS, SUD, B-P and BPD using the Mini International Neuropsychiatric Interview for DSM-5 and the Diagnostic Interview for Borderline (DIB-R). RESULTS B-P had a 100% negative predictive value, and the combination of SUD plus HAS had a 100% positive predictive value. On a quantitative level, B-P, HAS and SUD were independent explanatory factors of the DIB-R total score. CONCLUSIONS The main limitations were the low number of patients, the single center analyses, the potential overlapping of assessments and the fact that data were exclusively declarative. In this study, every patient with B-P, SUD and HAS had been diagnosed with BPD.

Abstract
Anorexia nervosa and bulimia nervosa are eating disorders associated with life-threatening multisystemic medical complications. This narrative review aimed to present the medical complications most related to these disorders. In anorexia nervosa, many of them are linked to malnutrition and underweight, usually reversible with renutrition and weight restoration, although refeeding can also be linked to some medical complications. Purging behaviors observed in the anorexia nervosa binge-purging subtype and bulimia nervosa have been mainly related to hydrolectrolyte and acid-base disturbances, in addition to local complications. Thus, an early identification and therapeutic intervention of these disorders is considered crucial. Integral medical monitoring should be ensured to prevent potential serious complications from the early stages, with the involvement of physicians, psychologists, nutritionists, and other specialists in a multidisciplinary approach according to the patient's needs.

Abstract
PURPOSE Insomnia and anorexia nervosa (AN) are frequently comorbid, negatively affecting the evolution and the prognosis of AN. Within this framework, the management of sleep disorders appears as critical. The aim of this retrospective study is to assess, for the first time, the efficacy of cognitive and behavioural therapy for insomnia (CBT-I) on sleep disturbances in adolescents with AN. To do so, we investigated the impact of CBT-I on sleep disturbances and sleep-related outcomes, in BMI, AN symptoms, anxiety and depressive symptoms, emotionality and quality of life. These features were compared between two groups of patients with AN, one following CBT-I, and the other receiving the regular treatment at the psychiatric unit. METHODS Data collection occurred between January and May 2022. The study included 42 adolescents in-treatment at the Eating Disorders care specialised unit at Salvator Hospital in Marseille. They were randomly assigned to the CBT-I group (N = 31) or the control group (N = 11). Several clinical elements were assessed using sleep diaries and self-report questionnaires. RESULTS Participants undergoing CBT-I showed a significant improvement in sleep latency, total wake time and sleep efficacy, as well as in physical well-being. No significant effects were found regarding AN symptoms. CONCLUSION These preliminary findings provide support for CBT-I effectiveness in adolescents with AN, as shown by significant improvements in several sleep parameters, as well as in physical well-being. These promising results, underline the relevance of this topic and its potential benefits for a more appropriate treatment for adolescents with AN. LEVEL OF EVIDENCE Level V, retrospective study.

Abstract
Importance Observational studies have associated anorexia nervosa with circadian rhythms and sleep traits. However, the direction of causality and the extent of confounding by psychosocial comorbidities in these associations are unknown. Objectives To investigate the association between anorexia nervosa and circadian and sleep traits through mendelian randomization and to test the associations between a polygenic risk score (PRS) for anorexia nervosa and sleep disorders in a clinical biobank. Design, Setting, and Participants This genetic association study used bidirectional 2-sample mendelian randomization with summary-level genetic associations between anorexia nervosa (from the Psychiatric Genomics Consortium) and chronotype and sleep traits (primarily from the UK Biobank). The inverse-variance weighted method, in addition to other sensitivity approaches, was used. From the clinical Mass General Brigham (MGB) Biobank (n = 47 082), a PRS for anorexia nervosa was calculated for each patient and associations were tested with prevalent sleep disorders derived from electronic health records. Patients were of European ancestry. All analyses were performed between February and August 2023. Exposures Genetic instruments for anorexia nervosa, chronotype, daytime napping, daytime sleepiness, insomnia, and sleep duration. Main Outcomes and Measures Chronotype, sleep traits, risk of anorexia nervosa, and sleep disorders derived from a clinical biobank. Results The anorexia nervosa genome-wide association study included 16 992 cases (87.7%-97.4% female) and 55 525 controls (49.6%-63.4% female). Genetic liability for anorexia nervosa was associated with a more morning chronotype (β = 0.039; 95% CI, 0.006-0.072), and conversely, genetic liability for morning chronotype was associated with increased risk of anorexia nervosa (β = 0.178; 95% CI, 0.042-0.315). Associations were robust in sensitivity and secondary analyses. Genetic liability for insomnia was associated with increased risk of anorexia nervosa (β = 0.369; 95% CI, 0.073-0.666); however, sensitivity analyses indicated bias due to horizontal pleiotropy. The MGB Biobank analysis included 47 082 participants with a mean (SD) age of 60.4 (17.0) years and 25 318 (53.8%) were female. A PRS for anorexia nervosa was associated with organic or persistent insomnia in the MGB Biobank (odds ratio, 1.10; 95% CI, 1.03-1.17). No associations were evident for anorexia nervosa with other sleep traits. Conclusions and Relevance The results of this study suggest that in contrast to other metabo-psychiatric diseases, anorexia nervosa is a morningness eating disorder and further corroborate findings implicating insomnia in anorexia nervosa. Future studies in diverse populations and with subtypes of anorexia nervosa are warranted.

Abstract
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.

Abstract
RATIONALE Anorexia nervosa is characterized by an extreme fear of weight gain. Clinicians often prescribe meal replacement shakes if patients are unable or unwilling to consume typical foods. However, these shakes sometimes lack essential micronutrients, such as selenium, which may lead to health risks. Moreover, selenium deficiency induces macrocytic anemia. Herein, we present a case of a patient with anorexia nervosa with macrocytic anemia due to selenium deficiency, which was alleviated by selenium supplementation. PATIENT CONCERNS An 18-year-old female was admitted to our hospital. The patient was diagnosed with anorexia nervosa. Ultimately, she was unable to walk independently because of fatigue and electrolyte disturbances. CLINICAL FINDINGS On admission, the height, weight, and body mass index of the patient were 158.5 cm, 27.1 kg, and 10.8, respectively. Our treatment for anorexia nervosa showed relative effectiveness, and the patient's body weight recovered to 29.2 kg by day 60. However, the mean corpuscular volume increased from day 20, suggesting macrocytic anemia. DIAGNOSES, INTERVENTIONS, AND OUTCOMES Despite our vitamin B12 and folic acid supplementation interventions, the mean corpuscular volume continued to rise. On day 60, the patient was diagnosed with selenium deficiency, and selenium administration of 100 μg/day was initiated. OUTCOMES The macrocytic anemia in the patient was alleviated, and treatment for anorexia nervosa was continued in our hospital. LESSONS To the best of our knowledge, this is the first case of macrocytic anemia induced by selenium deficiency with anorexia nervosa comorbidity, underscoring the importance of selenium supplementation in patients with anorexia nervosa, especially in those with macrocytic anemia.

Abstract
Recent evidence suggests a crucial role of the gut microbiota in the pathogenesis of anorexia nervosa (AN). In this study, we carried out a series of multiple analyses of the gut microbiota of hospitalized individuals with AN over three months using 16S or 23S rRNA-targeted reverse transcription-quantitative polymerase chain reaction (PCR) technology (YIF-SCAN®), which is highly sensitive and enables the precise quantification of viable microorganisms. Despite the weight gain and improvements in psychological features observed during treatment, individuals with AN exhibited persistent gut microbial dysbiosis over the three-month duration. Principal component analysis further underscored the distinct microbial profile of individuals with AN, compared with that of age-matched healthy women at all time points. Regarding the kinetics of bacterial detection, the detection rate of Lactiplantibacillus spp. significantly increased after inpatient treatment. Additionally, the elevation in the Bifidobacterium counts during inpatient treatment was significantly correlated with the subsequent body weight gain after one year. Collectively, these findings suggest that gut dysbiosis in individuals with AN may not be easily restored solely through weight gain, highlighting the potential of therapeutic interventions targeting microbiota via dietary modifications or live biotherapeutics.

Abstract
People suffering from anorexia have a particular emotional and cognitive profile (altered body and self-perception, emotional dysregulation, perfectionism, obsessive traits), which the disorder can compensate for through emotional distancing strategies. Self-compassion and unconditional self-acceptance have been shown to have therapeutic effects on the barriers to recovery associated with this profile.

Abstract
Anorexia nervosa affects people of all ages, and has the highest mortality rate of all psychiatric disorders, following medical complications inherent in the disease or suicide. Early and appropriate treatment is crucial to prevent the risk of chronic disease, which may affect one in two anorexics. Severe undernutrition linked to a complex psychopathology calls for the necessary theoretical and clinical knowledge on the part of the caregiver, applied to the dynamics of care, ideally conceived in a transdisciplinary way and involving nursing teams.

Abstract
ABSTRACT Major depressive disorder (MDD) is highly prevalent in individuals with anorexia nervosa (AN) and is a predictor of greater clinical severity. However, there is a limited amount of evidence supporting the use of psychotropic medications for its management. A systematic scoping review was conducted to assess the current literature on brain stimulation treatments for AN with comorbid MDD, with a specific focus on MDD treatment response and weight restoration. This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the PubMed, PsycInfo, and MEDLINE databases were searched until July 2022 using specific key words related to AN and brain stimulation treatments. A total of 373 citations were identified, and 49 treatment studies that met the inclusion criteria were included in the review. The initial evidence suggests that electroconvulsive therapy, repetitive transcranial magnetic stimulation, and deep-brain stimulation may be effective in managing comorbid MDD in AN. Emerging evidence suggests that transcranial direct current stimulation may have a positive effect on body mass index in individuals with severe to extreme AN. However, there is a need for the development of better measurement techniques for assessing the severity of depression in the context of AN. Controlled trials that are adequately designed to account for these limitations are highly warranted for deep-brain stimulation, electroconvulsive therapy, and repetitive transcranial magnetic stimulation and hold promise for providing clinically meaningful results.

Abstract
Anorexia Nervosa (AN) causes harmful underweight and important cardiovascular acute complications however less is known about longer-term cardiovascular risk. We measured carotid femoral pulse wave velocity (PWV) in a group of underweight young women with AN at baseline and weekly as they were refed and gained weight. PWV decreased over time and was negatively associated with increasing BMI and calorific meal content suggesting potential positive cardiovascular benefits for refeeding and weight gain in AN and supports current consensus for the importance of weight gain in underweight young women with AN.

Abstract
INTRODUCTION Migraine is a common primary headache disorder, which affects mainly young females, usually those with some specific personality traits including neuroticism and obsessive-compulsive disorder. Among many factors that may trigger headache are to be found those associated with eating patterns and behaviours. Eating disorders are psychiatric disorders of abnormal eating or weight-control behaviours. According to the most up-to-date classification, six main types are identified, including anorexia nervosa, bulimia nervosa, and binge eating disorder. Similar to migraine, eating disorders are mainly diagnosed in young adults and, moreover, personality pattern, in at least some of the eating disorders, is also suggested to be consistent. MATERIAL AND METHODS This systematic review aimed to summarise the available literature related to this topic. We performed an electronic article search through the Embase, PubMed, and Cochrane databases and included 16 articles into analysis in accordance with PRISMA 2020 guidelines. RESULTS Most of the studies revealed the presence of a putative correlation between migraine and eating disorders, and these encourage further investigations. Moreover, apart from the clinical aspect, also the pathogenesis underlying both disorders is suggested to be similar. More frequent co-occurrence of other psychiatric disorders in migraineurs, such as depression and anxiety, was reported and should be considered in future research. Furthermore, adverse interactions between pharmacotherapy and symptoms of comorbid conditions underline the importance of this problem. CONCLUSIONS A correlation between migraine and eating disorders appears highly probable. However, further investigations are required focusing on diverse aspects such as clinical, psychological, and pathogenic.

Abstract
BACKGROUND Superior mesenteric artery (SMA) syndrome is an underdiagnosed complication in anorexia nervosa (AN) patients, which results from weight loss-induced atrophy of the mesenteric fat pad, causing compression of the third part of the duodenum. SMA syndrome can be life-threatening as its nonspecific symptomatology often results in a delayed diagnosis. It is a rare condition, but its true prevalence may be higher than the reported numbers. A history of persistent nausea and vomiting after oral intake and weight loss in AN should raise suspicion about this diagnosis, as weight loss is the most significant factor in this diagnosis. Other high-risk factors include rapid, extreme weight loss, anatomical abnormalities, or a history of prior abdominal or spinal surgeries. CASE PRESENTATION The patient presented in this report was a 26-year-old Caucasian female with a history of severe enduring anorexia nervosa. This patient suffered from an insidious case of SMA syndrome secondary to AN. This patient presented with vague symptoms of nausea and vomiting, persistent abdominal pain, and rapid weight loss. The patient was successfully treated but could have had a much different outcome if the diagnosis had been further delayed. CONCLUSIONS An awareness of SMA syndrome and its clinical presentation within similar populations can prevent complications and even fatalities that come with it.

Abstract
PURPOSE To determine whether hypercapnia is associated with risk of hospital readmission related to anorexia nervosa (AN) in children and adolescents. METHODS We performed a prospective study of patients ≤ 18 years old admitted due to AN decompensation from November 2018 to October 2019. Both subtypes of AN, restricting subtype (AN-R) and binge-eating/purging subtype (AN-BP), were included. Study participants were evaluated upon admission, at discharge and six months after discharge. T-tests or Mann-Whitney U tests was used to compare means values. Pearson or Spearman correlations were used to measure the association between two variables. Logistic regression models were developed to evaluate the relationship between scoring methods and readmission. RESULTS Of the 154 persons admitted during the study period, 131 met the inclusion criteria. Median age was 15.1 years. At admission, 71% of participants were malnourished and 33 (25%) had been previously admitted. We observed a marked decrease in venous pH and stable pCO2 elevation during follow-up period. Hypercapnia at discharge was associated with a twofold increased likelihood of readmission and the odds of readmission increased as discharge pCO2 rose. These findings did not depend on AN subtype or participant sex. Electrolytes persisted within the normal range. CONCLUSION Hypercapnia and respiratory acidosis are common alterations in children and adolescents hospitalized due to AN decompensation. Hypercapnia persists for at least 6 months after discharge despite clinical improvement and is associated with higher odds of readmission. This is the first study to identify an abnormal laboratory finding as a potential predictor of readmission in AN. LEVEL OF EVIDENCE IV: Multiple time series without intervention.

Abstract
Researchers have reported increased fracture risk in patients with anorexia nervosa (AN), but more knowledge on the long-term risk and the effects of age, male sex, and time-related changes is still needed. We examined the long-term (up to 40 years) fracture risk among patients with AN compared to a matched comparison cohort from the general population. We utilized data from the Danish Health Care Registers to identify 14,414 patients with AN (13,474 females and 940 males) diagnosed between 1977 and 2018, with a median age of 18.6 years and median follow-up time of 9.65 years. We calculated adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) using Cox regression analysis for overall and site-specific fracture risks. The overall aHR of any fracture was 1.46 [95% CI: 1.36 to 1.48], with an aHR of 1.50 [95% CI: 1.43 to 1.57] for females and 0.95 [95% CI: 0.82 to 1.1] for males. For specific fractures we found an association with femur fractures both in females 4.06 [95% CI: 3.39 to 4.46] and in males 2.79 [95% CI: 1.45 to 2.37] and for fractures of the spine (females 2.38 [95% CI: 2.00 to 2.84], males 2.31 [95% CI: 1.20 to 4.42]). The aHR of any fracture decreased from 1.66 [95% CI: 1.52 to 1.81] in the period from 1977 to 1997 to 1.40 [95% CI: 1.33 to 1.40] from 1998 to 2018. In conclusion, we found that AN was associated with a 46% increased risk of any fracture up to 40 years after diagnosis. We found no overall increased risk in males, but in both sexes we found a particularly high site-specific fracture risk in the spine and femur. Fracture risk decreased in recent decades, indicating that more patients with AN have been diagnosed with presumably less severe disease and that the earlier detection and intervention of AN in recent years may translate into a lower facture risk. © 2023 The Authors.

Abstract
Anorexia nervosa (AN) has a high mortality rate due to the widespread organ dysfunction caused by the underlying severe malnutrition. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases, while acute liver failure and aplastic crisis related to coagulation disease and encephalopathy rarely occur in AN patients. The supervised increase of caloric intake can quickly improve the elevated aminotransferases caused by starvation and aplastic crisis. This current case report describes a 12-year-old adolescent girl who was admitted with a 3-month history of weight loss. Within 3 months, she had lost 10 kg of weight. The girl was diagnosed with AN, acute liver failure, severe malnutrition with emaciation, electrolyte disorder, bradycardia and aplastic crisis. She was gradually supplemented with vitamins and enteral nutrition to avoid refeeding syndrome. After treatment, her liver function and haematopoietic function returned to normal. In conclusion, acute liver failure and aplastic crisis are rare but potentially life-threatening complications of AN, which could be improved by supervised feeding and timely rehydration. AN should be considered as the potential aetiology of acute liver failure and aplastic crisis.

Yoshida T, Namiki T, Yamaga M, Onishi S, Takemoto M. Iron overload may be critical for liver dysfunction in anorexia nervosa, and the role of haematocrit-adjusted albumin in assessing nutritional status: a case report. BMC Pediatr 2023; 23:547. [PMID: 37907890 PMCID: PMC10617211 DOI: 10.1186/s12887-023-04367-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2023] [Accepted: 10/14/2023] [Indexed: 11/02/2023] Open
Abstract
BACKGROUND Anorexia nervosa (AN) is frequently associated with liver dysfunction, but the precise mechanism remains undefined. Since the nutritional marker albumin has a low correlation with changes in body weight in AN, and patients with AN often have dehydration as a complication, we also examined whether haematocrit (HCT)-adjusted serum albumin could be a better nutritional marker in AN. CASE PRESENTATION We describe a 15-year-old girl with severe weight loss and liver damage whose liver enzymes normalized after 1.5 months of hospitalization and weight gain. We found a significant correlation between body weight (BW) and HCT-adjusted serum albumin (Spearman's rank correlation coefficient (rs) = 0.66, P = 5.28 × 10-3) and between BW and alanine aminotransferase (ALT) (rs = -0.825, P = 8.45 × 10-5). After division by HCT, correlations between serum albumin and ALT (rs = -0.835, P = 5.24 × 10-5) and between the iron-storage protein ferritin and the liver enzyme gamma-glutamyl transferase (rs = 1.0, P = 0.017) were also statistically significant. CONCLUSION These results suggest that improvement of the nutritional status in AN could relieve liver dysfunction and facilitate iron transport. Since a decrease in the iron-transport protein transferrin presumably increases labile non-transferrin-bound iron, resulting in excess reactive oxygen species production, a defect in iron transport due to malnutrition could be one of the causes of liver injury in AN. In addition, HCT-adjusted albumin could be a better marker than its raw data to assess changes in nutritional status in AN.

Abstract
PURPOSE Severe malnourishment may reduce cognitive performance in anorexia nervosa (AN). We studied cognitive functioning during intensive nutritional and medical stabilization in patients with severe or extreme AN and investigated associations between weight gain and cognitive improvement. METHODS A few days after admission to a specialized hospital unit, 33 patients with severe or extreme AN, aged 16-42 years, completed assessments of memory, cognitive flexibility, processing speed, and attention. Mean hospitalization was 6 weeks. Patients completed the same assessments at discharge (n = 22) following somatic stabilization and follow-up up to 6 months after discharge (n = 18). RESULTS The patients displayed normal cognitive performance at admission compared to normative data. During nutritional stabilization, body weight increased (mean: 11.3%; range 2.6-22.2%) and memory, attention, and processing speed improved (p values: ≤ 0.0002). No relationship between weight gain and cognitive improvement was observed at discharge or follow-up. CONCLUSIONS Cognitive performance at hospital admission was normal in patients with severe or extreme AN and improved during treatment although without association to weight gain. Based on these results, which are in line with previous studies, patients with severe or extreme AN need not be excluded from cognitively demanding tasks, possibly including psychotherapy. As patients may have other symptoms that interfere with psychotherapy, future research could investigate cognitive functioning in everyday life in patients with severe AN. TRIAL REGISTRATION NUMBER The study is registered at clinicaltrials.gov (NCT02502617). LEVEL OF EVIDENCE Level III, cohort study.

Abstract
BACKGROUND Patients with anorexia nervosa (AN) may experience life-threatening malnutrition-related complications requiring inpatient medical stabilisation. Several management guidelines have been developed but discrepancies exist because of limited high-level evidence. AIMS To review the evidence base for recommendations contained in Victorian health services guidelines for the nutritional management of inpatients with AN. METHODS MEDLINE and Embase databases were searched for published studies on the nutritional management of inpatients with AN, combined with a manual search through citations. Studies including patients with AN aged 16 years and older were included. Case reports, small case series of <10 patients, studies of nonmedical management and studies with an exclusive paediatric population were excluded. The search results were compared with AN inpatient medical management guidelines sourced from large tertiary health services across Victoria, Australia. RESULTS The search yielded 584 studies, subsequently reduced to nine studies using the inclusion and exclusion criteria. The results suggest that commencing refeeding at a higher caloric value allows faster weight gain and shorter hospitalisation. Enteral tube feeding is preferential to parenteral nutrition because of infrequent and milder complications. Zinc supplementation showed a doubled rate of body mass index increase compared with placebo. Comparison with Victorian health services guidelines revealed inconsistent recommendations for high-calorie refeeding and micronutrient supplementation. CONCLUSION The evidence supports high-calorie refeeding of 2000 kcal/day in AN inpatient medical management and zinc supplementation in improving the rate of weight restoration. This is inconsistently reflected in different Victorian health services guidelines. Updated national consensus guidelines could assist in improving consistency of evidence-based health care.

Abstract
BACKGROUND This study was carried out to assess the effects of omega-3 supplementation as an adjunct treatment for eating and psychological symptoms in patients with anorexia nervosa. METHODS We conducted a systematic review of the literature using the terms 'anorexia nervosa' AND 'Fatty Acids, Omega-3'. Five randomised controlled trials with a total of 144 participants, published between 2003 and 2022, were included. RESULTS The effects of supplementation of omega-3 on anxiety were standardised mean difference (SMD) 0.79, 95% confidence interval (CI) -0.08 to 1.66; p = 0.08; I² = 3%; two studies, 33 participants; moderate quality of evidence. For depression, the supplementation of omega-3 was SMD: 0.22, 95% CI: -0.50 to 0.93; p = 0.18; I² = 45%; two studies, 33 participants; moderate quality of evidence. For obsessive-compulsive disorder, the supplementation of omega-3 was SMD: -0.22, 95% CI: -0.70 to 2.25; p = 0.36; I² = 0%; three studies, 32 participants; low quality of evidence. CONCLUSION This research showed that regardless of dose, time or, if associated with other components, the use of omega-3 supplementations as an adjuvant treatment showed no evidence of effect in eating and psychological symptoms in patients with anorexia nervosa.

Abstract
BACKGROUND Anorexia nervosa (AN) is associated with maladaptive cardiovascular changes. This study investigated whether individuals who recovered from AN during adolescence experience long-term cardiovascular risk in early adulthood. METHODS Former AN patients discharged from the Royal Children's and Monash Children's Hospital Eating Disorder Services in Melbourne, Australia underwent cardiovascular testing. Measurements were performed using an oscillometric device for blood pressure and pulse wave velocity, ultrasound for carotid wall structure/function, resting electrocardiogram for heart-rate variability, and the EndoPat 2000 (Itamar) system for endothelial function. Patient measures were compared to healthy controls and/or normal thresholds. RESULTS Ninety-one percent of the former AN patients (N = 22) and controls (N = 66) were female, aged approximately 25 years, with a healthy body mass index. The mean time interval from AN recovery to participation was 7.4 years. Pulse wave velocity was lower in the former AN patients than controls. Carotid intima-media thickness was not different; however, carotid distensibility and compliance were lower, and the elastic modulus higher in the former AN patients. Greater vagal tone was observed and endothelial dysfunction was evident in 46% of the former patients. CONCLUSIONS Young adults who recovered from adolescent AN exhibit persistent cardiovascular adaptations. Routine cardiovascular monitoring could manage potential disease risk. IMPACT Cardiovascular complications are common in patients with anorexia nervosa (AN) and population studies have revealed that developmental adaptations in response to undernutrition have long-term consequences for cardiovascular health. In this study of young adults treated for AN during adolescence, there was evidence of increased carotid artery stiffness, reduced aortic stiffness, vagal hyperactivity, and endothelial dysfunction in early adulthood when compared to healthy controls. It is important to consider the cardiovascular health of patients with AN beyond achieving medical stability. Interventions that monitor cardiovascular health could minimise the burden of future cardiovascular disease.

Abstract
Delusional thinking is a key symptom of first-episode psychosis (FEP), but it has also been studied in obsessive-compulsive disorder (OCD) and anorexia nervosa (AN). This study aimed to analyze the psychometric properties of the Brown Assessment of Beliefs Scale (BABS) in a sample of adolescents diagnosed with a FEP, AN, or OCD, and to compare delusional thinking among the three samples. The sample comprised 60 patients in three groups of 20 diagnosed with OCD, AN, or FEP. Participants underwent assessment by diagnostic interview, the BABS scale, and a measure of depressive symptomatology. Specific instruments were also used to assess the main symptomatology of each disorder. The BABS had good internal consistency, and high validity and reliability. The OCD group scored significantly lower than the other two groups in all scale items except for items 4 (fixation of ideas), 6 (insight), and 7 (delusions of reference). A significant difference only existed between the AN and FEP groups for item 7 (delusions of reference). The BABS scale is a valid and reliable tool for assessing delusionality in adolescents diagnosed with OCD, AN, or FEP, with evidence of marked differences between the disorders. Assessing these symptoms could influence management, helping to improve treatment adherence and prognosis.

Abstract
INTRODUCTION Nutritional status assessment in anorexia nervosa (AN) includes the evaluation and monitoring of body composition throughout the treatment period. The gold standard for the study of body composition is dual-energy X-ray absorptiometry (DEXA), although electrical bioimpedance (BIA) is a more accessible, cheaper and faster method that does not involve exposure to radiation. MATERIAL AND METHODS We recruited 33 female adolescents with AN (age, 11.7-16.3 years) by consecutive sampling. We collected data on clinical, anthropometric and laboratory variables. Patients were assessed with BIA and DEXA at inclusion in the study and at the end of the study, with a mean duration of follow-up of 1 year, during the nutritional rehabilitation phase. RESULTS There was significant improvement in nutritional status, reflected by the body composition obtained by anthropometric measurements and BIA. The phase angle increased significantly during the follow-up. Greater weight loss was associated with the presence of secondary amenorrhoea and decreased bone mineral density in the spine. CONCLUSIONS Electrical BIA is a useful tool for assessment and monitoring of nutritional status in paediatric patients with AN. Dual-energy X-ray absorptiometry continues to be essential to assess bone mineral density. The role of hormones such as leptin remains to be elucidated.
