Cuerva K, Spirou D, Cuerva A, Delaquis C, Raman J. Perspectives and preliminary experiences of psychedelics for the treatment of eating disorders: A systematic scoping review. EUROPEAN EATING DISORDERS REVIEW 2024; 32:980-1001. [PMID: 38783636 DOI: 10.1002/erv.3101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 04/10/2024] [Accepted: 04/26/2024] [Indexed: 05/25/2024]
Abstract
OBJECTIVE Research regarding the therapeutic application of psychedelics and psychedelic-assisted psychotherapy in the treatment of eating disorders (EDs) has begun to emerge. This systematic scoping review aimed to map and synthesise the existing evidence regarding the participant reported efficacy and perspectives concerning psychedelics in the treatment of EDs, and to identify significant research gaps. METHOD A systematic search was undertaken across several databases in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. RESULTS 1290 publications were identified, 1135 after duplicates removed, with 17 meeting full-eligibility criteria. Overall, findings suggested that most participants reported experiencing a meaningful reduction in their ED symptoms and having positive experiences or an openness to explore psychedelics as a treatment for ED symptoms, although some noted concerns of adverse effects and the importance of having psychological support to increase safety and efficacy. CONCLUSIONS While preliminary research suggests psychedelics and psychedelic-assisted psychotherapy may be a viable treatment option for ED symptoms, further research with more robust research designs is required to increase confidence in its efficacy, generalisability, and safety as a therapeutic medium.

Abstract
INTRODUCTION Anorexia Nervosa (AN) is a complex psychiatric illness, characterized by a high risk of developing cardiovascular complications. Given the high risk of vascular diseases in patients with AN, we can assume that patients with severe AN have a high risk of developing ischemic stroke. However, to the best of our knowledge, no reports of patients with AN presenting with ischemic stroke have been published, other than a report of the development of IS during refeeding therapy in patients with severe AN. CASE PRESENTATION The present case report is aimed at describing the characteristics of an ischemic stroke occurring in a 19-year-old university student who had a 6-month history of AN. She was a non-smoker, had no relevant medical history and no family history of stroke. Upon hospital admission due to symptoms of stroke (aphasia and facial droop), she exhibited severe malnutrition with a BMI of 12.8 kg/m2. Computerized tomography imaging revealed occlusion of the left M2 branch and a congruous extensive area of hypoperfusion. Further investigations ruled out all common causes of stroke: she had no vascular stenosis, no heart diseases or arrhythmias, and no shunts, and gave negative results in autoimmune, toxicological and thrombophilia screenings. CONCLUSION Clinicians should suspect development of severe complications, including ischemic stroke, in patients with severe AN. Further extensive group studies or group-based studies are needed to elucidate the etiology of ischemic stroke in patients with severe AN. This will enable us to develop more precise and effective interventions.

Secondary carnitine deficiency during refeeding in severely malnourished patients with eating disorders: a retrospective cohort study. J Eat Disord 2024; 12:97. [PMID: 38982532 PMCID: PMC11232142 DOI: 10.1186/s40337-024-01054-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 06/22/2024] [Indexed: 07/11/2024] Open
Abstract
BACKGROUND Secondary carnitine deficiency in patients with anorexia nervosa has been rarely reported. This study aimed to investigate the occurrence of carnitine deficiency in severely malnourished patients with eating disorders during refeeding and assess its potential adverse effects on treatment outcomes. METHOD In a cohort study of 56 female inpatients with eating disorders at a single hospital from March 2010 to December 2020, we measured plasma free carnitine (FC) levels and compared to those of a healthy control group (n = 35). The patients were categorized into three groups based on FC levels: FC deficiency (FC< 20 µmol/L), FC pre-deficiency (20 µmol/L ≤ FC< 36 µmol/L), and FC normal (36 µmol/L ≤ FC). RESULTS Upon admission, the patients had a median age of 26 years (interquartile range [IQR]: 21-35) and a median body mass index (BMI) of 13.8 kg/m2 (IQR: 12.8-14.8). Carnitine deficiency or pre-deficiency was identified in 57% of the patients. Hypocarnitinemia was associated with a decline in hemoglobin levels during refeeding (odds ratio [OR]: 0.445; 95% confidence interval [CI]: 0.214-0.926, p = 0.03), BMI at admission (OR: 0.478; 95% CI: 0.217-0.874, p = 0.014), and moderate or greater hepatic impairment at admission (OR: 6.385; 95% CI: 1.170-40.833, p = 0.032). CONCLUSIONS Hypocarnitinemia, particularly in cases of severe undernutrition (BMI< 13 kg/m2 at admission) was observed in severely malnourished patients with eating disorders during refeeding, a critical metabolic transition phase. Moderate or severe hepatic impairment at admission was considered a potential indicator of hypocarnitinemia. Although hypocarnitinemia was not associated with any apparent adverse events other than anemia during refeeding, the possibility that carnitine deficiency may be a risk factor for more serious complications during sudden increases in energy requirements associated with changes in physical status cannot be denied. Further research on the clinical significance of hypocarnitinemia in severely malnourished patients with eating disorders is warranted.

Abstract
OBJECTIVE Dietitians have a central role in eating disorder (ED) treatment, however few studies exist investigating therapeutic aspects of dietetic care and factors influencing the dietitian-patient relationship. To address the gap, this study aimed to use a qualitative description approach to explore the experiences of delivering and receiving dietetic care in ED treatment in the UK. METHOD Semi-structured interviews were conducted with 6 specialist ED dietitians and focus groups with 11 recovered ED patients. Interviews were transcribed and inductive thematic analysis was performed to identify key themes describing the data. RESULTS Six key themes were generated: (1) Building trust, (2) Appropriate timing, (3) Adapting, (4) Dietitians as experts, (5) Boundaries, and (6) Difficult relationships. Participants highlighted the importance of building trust and considering nutritional risk and readiness in treatment approach. Patients expressed a desire for dietitians to have experience in EDs, facilitating understanding of their illness. However, dietitians identified the nature of EDs making their role challenging at times. DISCUSSION This study described various factors affecting dietetic care in EDs and provided a valuable insight into patients' perceptions of treatment. The findings support advancements in ED dietitians' knowledge and understanding, helping to enhance quality of care.

Abstract
BACKGROUND Eating disorders (EDs) are serious conditions predominantly affecting adolescents and young adults (AYAs) and pose a considerable threat to their health and wellbeing. Much of this increased morbidity and mortality is linked to medical compromise, especially cardiovascular abnormalities. Rates of presentation to both community and inpatient medical settings have increased in all age groups following the Covid-19 pandemic and subsequent "lockdowns", with patients presentations being more medically compromised compared to previous years. This has implications for clinicians with regard to the performance of competent cardiovascular assessments and management of findings. AIMS This paper is a practical resource for clinicians working with AYAs in whom EDs may present. It will provide a brief summary of the physiological context in which cardiovascular complications develop, systematically outline these complications and suggest a pragmatic approach to their clinical evaluation. METHODS Relevant literature, guidelines and academic texts were critically reviewed. Conclusions were extracted and verified by a Child and Adolescent Psychiatrist and Adolescent Paediatrician, with suitable expertise in this clinical cohort. CONCLUSIONS The cardiovascular complications in EDs are primarily linked to malnutrition, and patients presenting with Anorexia Nervosa are most often at greatest risk of structural and functional cardiac abnormalities, including aberrations of heart rate and rhythm, haemodynamic changes and peripheral vascular abnormalities. Other cardiovascular abnormalities are secondary to electrolyte imbalances, as seen in patients with Bulimia Nervosa. More recently defined EDs including Avoidant/Restrictive Food Intake Disorder and Binge Eating Disorder are also likely associated with distinct cardiovascular complications though further research is required to clarify their nature and severity. Most cardiovascular abnormalities are fully reversible with nutritional restoration, and normalisation of eating behaviours, including the cessation of purging, though rare cases are linked to cardiac deaths. A detailed clinical enquiry accompanied by a thorough physical examination is imperative to ensure the medical safety of AYAs with EDs, and should be supported by an electrocardiogram and laboratory investigations. Consideration of cardiovascular issues, along with effective collaboration with acute medical teams allows community clinicians identify those at highest risk and minimise adverse outcomes in this cohort.

Abstract
PURPOSE Anorexia nervosa (AN) is the most frequent eating disorder (ED), whose cardiac complications may have life-threatening consequences for both the physical and psychological health of affected children. In this study, we reported and analysed the echocardiographic anomalies found in pediatric patients diagnosed with AN. METHODS We reported the demographic and clinical characteristics of children aged 8 to 18 years, who were diagnosed with AN and underwent a complete cardiological evaluation at the Emergency Department of the Bambino Gesù Children's Hospital, IRCCS, Rome between the 1st January 2021 and the 30th June 2021. Furthermore, we compared the patients according to the presence of pericardial effusion and a BMI (body mass index) cut-off 14.5 kg/m2. RESULTS Forty-nine patients were included in the study. The mean age was 15.1 years. Most patients were female (89.8%). The mean length of hospitalization was 18 days. The mean BMI at admission was 14.8 kg/m2, with a median weight loss of 9 kg in the last year. Eleven patients (22.4%) presented with cardiovascular signs or symptoms at admission. Most patients had pericardial effusion on heart ultrasound, with a mean thickness of 6 mm (SD ± 4). The LV (left ventricle) thickness over age was significantly higher in patients with pericardial effusion, with a Z score of -2.0 vs -1.4 (p = 0.014). The administration of psychiatric drugs was significantly more frequent in patients with a lower BMI (37.5% vs 12%, p = 0.038). CONCLUSION Our study suggests that a non-urgent baseline echocardiographic evaluation with focus on left-ventricular wall thickness and mass in children with anorexia nervosa is advisable. LEVEL III Evidence obtained from cohort or case-control analytic studies.

Abstract
PURPOSE Eating disorders often result in somatic complications, including cardiac abnormalities. Cardiac abnormalities may involve any part of the heart, including the cardiac conduction system, and can lead to sudden cardiac death. The current study aimed to evaluate the incidence of cardiac complications in pediatric patients with eating disorders and their associated factors. METHODS We retrospectively analyzed patients aged 10-18 years who were diagnosed with DSM-V (Diagnostic and Statistical Manual of Mental Disorder-V) eating disorders and underwent electrocardiography (ECG) and/or echocardiography between January 2015 and May 2020. RESULTS In total, 127 patients were included, of whom 113 (89.0%) were female. The median body mass index (BMI) was 15.05±3.69 kg/m2. Overall, 74 patients (58.3%) had ECG abnormalities, with sinus bradycardia being the most common abnormality (91.9%). Patients with ECG abnormalities had significantly lower BMI (14.35±2.78 kg/m2 vs. 16.06± 4.55 kg/m2, p<0.001) than patients without ECG abnormalities, as well as lower phosphorus and higher cholesterol levels. Among the 46 patients who underwent echocardiographic evaluation, 23 (50.0%) had echocardiographic abnormalities, with pericardial effusion being the most common (60.9%). The median left ventricular mass (LVM) and ejection fraction were 67.97±21.25 g and 66.91±28.76%, respectively. LVM and BMI showed a positive correlation (r=0.604, p<0.001). After weight gain, the amount of pericardial effusion was reduced in 3 patients, and 30 patients presented with normal ECG findings. CONCLUSION Cardiac abnormalities are relatively frequent in patients with eating disorders. Physicians should focus on this somatic complication and careful monitoring is required.

Decision-Making in Childhood Predicts Prodromal Eating Pathology in Adolescence. J Dev Behav Pediatr 2022; 43:e407-e413. [PMID: 35353769 DOI: 10.1097/dbp.0000000000001073] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Accepted: 01/27/2022] [Indexed: 11/26/2022]
Abstract
OBJECTIVE Differences in decision-making under conditions of risk have been observed cross-sectionally in clinical groups of people with eating disorders but have never been studied longitudinally or in large cohorts. We investigated whether responses on the Cambridge Gambling Task (CGT), measured in the Millennium Cohort Study in childhood, would predict prodromal eating pathology in adolescence. METHOD Regression models were built to explore relationships between CGT variables at age 11 years and prodromal eating pathology (body dissatisfaction, intention to lose weight, dietary restriction, significant under/overweight, and excessive exercise) at 14 years. RESULTS In 11,303 boys and girls, those with better quality decision-making were 34% less likely to show an intention to lose weight (b = -0.40, odds ratio [OR] = 0.66, p < 0.05) and 34% less likely to be overweight (b = -0.41, relative risk ratio [RRR] = 0.66, p < 0.05). Those with higher risk-taking were 58% more likely to report dietary restriction (b = 0.45, OR = 1.58, p < 0.05) and 46% more likely to report excessive exercise (b = 0.38, OR = 1.46, p < 0.05). In the complete-cases sample, higher risk-adjustment scores were associated with a 47% increased risk of underweight (b = 0.39, RRR = 1.47, p < 0.05), and better quality of decision-making was associated with a 46% lower risk of overweight (b = -0.60, RRR = 0.54, p < 0.05). CONCLUSION Disadvantageous decision-making in childhood may predict prodromal eating pathology in adolescence and might represent a prevention target.

Abstract
OBJECTIVE DSM-5 Atypical Anorexia Nervosa (AAN), a new eating disorder diagnosis, presents similarly to Anorexia Nervosa (AN) in the absence of severe underweight. The prevalence of AAN and other DSM-5 eating disorders was estimated in a sample of Veterans. Sociodemographic, mental health, and eating behavior correlates were examined. METHOD Iraq and Afghanistan war era Veterans (N = 1137, 51.6% female) completed the Eating Disorder Diagnostic Scale-5 for probable AAN diagnosis, and validated measures of eating pathology and mental health, between February 2016 and October 2019. Multivariate analyses compared Veterans with AAN to those with and without any DSM-5 eating disorder. RESULTS Among completers, 13.6% of women and 4.9% of men in the sample met criteria for probable AAN and 19.2% of women and 13.9% of men for another eating disorder. Mean age was 41 years, and on average BMIs were classified as overweight (BMI = 28.8, SD = 5.6) despite being at least 10% lower than their lifetime highest weight. Two-thirds reported dietary restraint on more than half the days in the past month. On measures of mental health, the AAN group had worse functioning than the no eating disorder group, similar functioning to Veterans with Binge Eating Disorder (BED), and better functioning than Veterans with Bulimia Nervosa (BN). DISCUSSION Results support AAN as a highly prevalent and clinically significant diagnosis. Findings highlight the need to identify and address eating disorders, particularly other specified eating disorders not meeting criteria for AN, BN, or BED, in active military and Veteran, and other high-risk and underserved, populations.

Abstract
Anorexia nervosa (AN) is a kind of malnutrition resulting from chronic self-induced starvation. The reported associated endocrine changes (adaptive and non-adaptive) include hypothalamic amenorrhea, a nutritionally acquired growth hormone resistance with low insulin like growth factor-1 (IGF-1) secretion, relative hypercortisolemia, decreased leptin and insulin concentrations, and increased ghrelin, Peptide YY (PYY) and adiponectin secretion. The combined effect of malnutrition and endocrinopathy may have deleterious effects on multi-organs including bone, gonads, thyroid gland, and brain (neurocognition, anxiety, depression, and other psychopathologies). The mammalian target of rapamycin (mTOR) is a kinase that in humans is encoded by the mTOR gene. Recent studies suggest an important role of mTOR complex in integration of nutrient and hormone signals to adjust energy homeostasis. In this review, we tried to elucidate the role/s of mTOR as critical mediator of the cellular response in anorexia nervosa. (www.actabiomedica.it)

Abstract
Eating disorders affect a significant number of individuals across the life span and are found among all demographic groups (including all genders, socioeconomic statuses, and ethnicities). They can cause malnutrition, which can have significant effects on every organ system in the body. Cardiovascular complications are particularly dangerous and cause eating disorders to have the highest mortality rate of all mental illnesses. This article outlines the medical assessment and treatment of malnutrition due to disordered eating.

Abstract
The abuse of volatile solvents such as toluene is a significant public health concern, predominantly affecting adolescents. To date, inhalant abuse research has primarily focused on the central nervous system; however, inhalants also exert effects on other organ systems and processes, including metabolic function and energy balance. Adolescent inhalant abuse is characterized by a negative energy balance phenotype, with the peak period of abuse overlapping with the adolescent growth spurt. There are multiple components within the central and peripheral regulation of energy balance that may be affected by adolescent inhalant abuse, such as impaired metabolic signaling, decreased food intake, altered dietary preferences, disrupted glucose tolerance and insulin release, reduced adiposity and skeletal density, and adrenal hypertrophy. These effects may persist into abstinence and adulthood, and the long-term consequences of inhalant-induced metabolic dysfunction are currently unknown. The signs and symptoms resulting from chronic adolescent inhalant abuse may result in a propensity for the development of adult-onset metabolic disorders such as type 2 diabetes, however, further research investigating the long-term effects of inhalant abuse upon energy balance and metabolism are needed. This review addresses several aspects of the short- and long-term effects of inhalant abuse relating to energy and metabolic processes, including energy balance, intake and expenditure; dietary preferences and glycemic control; and the dysfunction of metabolic homeostasis through altered adipose tissue, bone, and hypothalamic-pituitary-adrenal axis function.

Abstract
Anorexia nervosa (AN) is an eating disorder that most frequently afflicts females in adolescence. In these subjects, cardiovascular complications are the main cause of morbidity and mortality. Aim of this review is to analyze the hemodynamic, pro-arrhythmic and structural changes occurring during all phases of this illness, including re-feeding. A systematic literature search was performed on studies in the MEDLINE database, from its inception until September 2017, with PUBMED interface focusing on AN and cardiovascular disease. This review demonstrated that the most common cardiac abnormalities in AN are bradycardia and QT interval prolongation, which may occasionally degenerate into ventricular arrhythmias such as Torsades des Pointes or ventricular fibrillation. As these arrhythmias may be the substrate of sudden cardiac death (SCD), they require cardiac monitoring in hospital. In addition, reduced cardiac mass, with smaller volumes and decreased cardiac output, may be found. Furthermore, mitral prolapse and a mild pericardial effusion may occur, the latter due to protein deficiency and low levels of thyroid hormone. In anorectic patients, some cases of hypercholesterolemia may be present; however, conclusive evidence that AN is an atherogenic condition is still lacking, although a few cases of myocardial infarction have been reported. Finally, refeeding syndrome (RFS), which occurs during the first days of refeeding, may engender a critically increased risk of acute, life-threatening cardiac complications.

Abstract
OBJECTIVE Objectification theory posits that self-objectification increases risk for disordered eating. METHOD The current study sought to examine the relationship between self-objectification and disordered eating using meta-analytic techniques. RESULTS Data from 53 cross-sectional studies (73 effect sizes) revealed a significant moderate positive overall effect (r = .39), which was moderated by gender, ethnicity, sexual orientation, and measurement of self-objectification. Specifically, larger effect sizes were associated with female samples and the Objectified Body Consciousness Scale. Effect sizes were smaller among heterosexual men and African American samples. Age, body mass index, country of origin, measurement of disordered eating, sample type and publication type were not significant moderators. DISCUSSION Overall, results from the first meta-analysis to examine the relationship between self-objectification and disordered eating provide support for one of the major tenets of objectification theory and suggest that self-objectification may be a meaningful target in eating disorder interventions, though further work is needed to establish temporal and causal relationships. Findings highlight current gaps in the literature (e.g., limited representation of males, and ethnic and sexual minorities) with implications for guiding future research.

Abstract
The severity of anorexia nervosa can vary from mild to life threatening. It is sometimes transient but often chronic. Such variety of disorder requires variety of response. The clinician must choose the right treatment to offer at the right time. The literature contains plenty of advice but most of this is based upon experience and opinion rather than on systematic research and treatment trials. For the most part, this paper will be no exception. Anorexia nervosa is a disorder which is distinct from other psychiatric syndromes but is of uncertain cause. In the face of this uncertainty, treatment tends to be informed by the favoured formulation of the clinician, usually some sort of ‘multifactorial theory’. Again this paper is no exception. It will concentrate upon the management of anorexia nervosa in late adolescence and adulthood. The treatment of children requires a different approach (Lask & Bryant-Waugh, 1993). The emphasis of the paper will be upon what can go wrong as well as what may be the best interventions to offer. Often the things that go wrong have more to do with the context of treatment and the way in which it is offered rather than with the treatment intervention itself.

Abstract
Nephrocalcinosis (NC) has been described as a long-term complication of anorexia nervosa (AN). This is the first report of this complication in an adolescent male patient. We describe the case of a 12-year-old male with AN who presented with acute food restriction and excessive exercising leading to three inpatient admissions. The patient experienced an isolated episode of dysuria and hematuria while on calcium and vitamin D supplementation. Investigations revealed hypophosphatemia, hypercalciuria and mild NC. Follow-up confirmed the presence of NC and possible nephrolithiasis (NL). We discuss the pathophysiology and risk factors of NC and NL in the context of an early presentation of AN. We suggest fluid intake should be liberalized under observation and calcium and vitamin D supplementation should be initiated with caution in patients presenting with AN and risk factors for NC and NL.

Abstract
UNLABELLED Introduction Anorexia nervosa is an eating disorder, which is associated with many different medical complications as a result of the weight loss and malnutrition that characterise this illness. It has the highest mortality rate of any psychiatric disorder. A large portion of deaths are attributable to the cardiac abnormalities that ensue as a result of the malnutrition associated with anorexia nervosa. In this review, the cardiac complications of anorexia nervosa will be discussed. METHODS A comprehensive literature review on cardiac changes in anorexia nervosa was carried out. RESULTS There are structural, functional, and rhythm-type changes that occur in patients with anorexia nervosa. These become progressively significant as ongoing weight loss occurs. CONCLUSION Cardiac changes are inherent to anorexia nervosa and they become more life-threatening and serious as the anorexia nervosa becomes increasingly severe. Weight restoration and attention to these cardiac changes are crucial for a successful treatment outcome.

Abstract
Background Anorexia nervosa (AN) is a complex psychiatric disease with a moderate to strong genetic contribution. In addition to conventional genome wide association (GWA) studies, researchers have been using machine learning methods in conjunction with genomic data to predict risk of diseases in which genetics play an important role. Methods In this study, we collected whole genome genotyping data on 3940 AN cases and 9266 controls from the Genetic Consortium for Anorexia Nervosa (GCAN), the Wellcome Trust Case Control Consortium 3 (WTCCC3), Price Foundation Collaborative Group and the Children’s Hospital of Philadelphia (CHOP), and applied machine learning methods for predicting AN disease risk. The prediction performance is measured by area under the receiver operating characteristic curve (AUC), indicating how well the model distinguishes cases from unaffected control subjects. Results Logistic regression model with the lasso penalty technique generated an AUC of 0.693, while Support Vector Machines and Gradient Boosted Trees reached AUC’s of 0.691 and 0.623, respectively. Using different sample sizes, our results suggest that larger datasets are required to optimize the machine learning models and achieve higher AUC values. Conclusions To our knowledge, this is the first attempt to assess AN risk based on genome wide genotype level data. Future integration of genomic, environmental and family-based information is likely to improve the AN risk evaluation process, eventually benefitting AN patients and families in the clinical setting.

Risk factors for elevated liver enzymes during refeeding of severely malnourished patients with eating disorders: a retrospective cohort study. J Eat Disord 2016; 4:37.

Abstract
BACKGROUND There are few previous reports regarding the cause and evolution of liver injury in patients with anorexia nervosa (AN) during the refeeding process, and its management remains controversial. This study aimed to determine the risk factors for elevated liver enzymes during refeeding and their effect on the therapeutic process in severely malnourished patients with eating disorders. METHODS In a retrospective cohort study of 167 female inpatients in a single hospital from January 2004 to March 2015, 67 who had normal alanine aminotransferase (ALT) levels on admission were divided into two groups according to the presence or absence of elevated ALT levels during refeeding, and then compared. RESULTS The median age and body mass index (BMI) of the patients on admission were 22 [interquartile range (IQR), 16-33] years and 12.2 (IQR, 11.1-13.0) kg/m2, respectively. Compared with their cohorts, significantly more patients in the early onset age group (<15 years old) had elevated ALT levels during refeeding (67% vs. 33%, p = 0.033), as did patients with longer median time to nadir BMI (3.0 vs. 0 days, p = 0.03). In addition, onset age [odds ratio (OR): 0.274; 95% confidence interval (CI): 0.077-0.981; p = 0.047] and time to nadir BMI (OR: 1.271; 95% CI: 1.035-1.56; p = 0.022) were significantly associated with the odds of elevated ALT levels during refeeding. CONCLUSIONS The results of this study suggest that early age at onset may be a potential risk factor for elevated ALT levels during refeeding in severely malnourished patients with eating disorders. Furthermore, elevated ALT levels during refeeding were significantly associated with delay in the start of weight gain. No significant relationship was found between the amount of initial prescribed calories and elevated ALT levels during refeeding. The median time to maximum ALT was 27 (IQR, 21-38) days after the refeeding process started.

Abstract
OBJECTIVE In a previous study we found that compulsory inpatient treatment was associated with an increase in the number of deaths over the following 5 years when compared to non-compulsory admission. This study aimed to examine the longer term mortality of patients admitted compulsorily. METHOD The mortality outcome of patients with a compulsory admission (n = 81) and a comparison group (n = 81) of patients admitted to the specialized eating disorder unit at the Maudsley Hospital in the period 1983-95 was traced over two decades through the National Register held by the National Health Service (NHS) Central Register. RESULTS Approximately 20 years following admission there were 27 deaths in the series. The standardized mortality rate in the compulsory treatment group no longer differed significantly from that of the non-compulsory group. The suicides were not particularly linked with compulsory admission. DISCUSSION Although the mortality in the 5 years following a compulsory admission is higher than that seen in the non-compulsory patients, this difference is attenuated over time. The overall standardized mortality rate remains elevated.

Abstract
Ingestive behaviors in mice are dependent on orosensory cues transmitted via the trigeminal nerve, as confirmed by transection studies. However, these studies cannot differentiate between deficits caused by the loss of the lemniscal pathway vs. the parallel paralemniscal pathway. The paired-like homeodomain protein Prrxl1 is expressed widely in the brain and spinal cord, including the trigeminal system. A knockout of Prrxl1 abolishes somatotopic barrellette patterning in the lemniscal brainstem nucleus, but not in the parallel paralemniscal nucleus. Null animals are significantly smaller than littermates by postnatal day 5, but reach developmental landmarks at appropriate times, and survive to adulthood on liquid diet. A careful analysis of infant and adult ingestive behavior reveals subtle impairments in suckling, increases in time spent feeding and the duration of feeding bouts, feeding during inappropriate times of the day, and difficulties in the mechanics of feeding. During liquid diet feeding, null mice display abnormal behaviors including extensive use of the paws to move food into the mouth, submerging the snout in the diet, changes in licking, and also have difficulty consuming solid chow pellets. We suggest that our Prrxl1(-/-) animal is a valuable model system for examining the genetic assembly and functional role of trigeminal lemniscal circuits in the normal control of eating in mammals and for understanding feeding abnormalities in humans resulting from the abnormal development of these circuits.

Abstract
Anorexia nervosa (AN) is an eating disorder in which a distorted self-perception of body image and an excessive fear of gaining weight result in extreme restrictions in eating habits. AN may be divided into two types: a "binge-eating/purging type" during which the individual regularly engages in overeating and then purging behavior, and a "restricting type", in which she does not. AN is a serious medical problem in young people in Western societies. It is widely reported that patients with AN exhibit an enhanced mortality rate as compared with age-matched healthy subjects, which has been mainly ascribed to cardiac complications. At least one-third of all deaths in patients with anorexia nervosa are estimated to be due to cardiac causes, mainly sudden death. Cardiovascular complications of AN can be present in up to 80% of cases, and among them alterations in cardiac electrical activity, structure and hemodynamics have been reported as causes of morbidity and mortality. The objective of this brief review is to summarize current knowledge on the main cardiovascular complications of AN, their underlying mechanisms and the possible therapeutic approaches.

Abstract
Anorexia nervosa (AN) is a complex and heritable eating disorder characterized by dangerously low body weight. Neither candidate gene studies nor an initial genome-wide association study (GWAS) have yielded significant and replicated results. We performed a GWAS in 2907 cases with AN from 14 countries (15 sites) and 14 860 ancestrally matched controls as part of the Genetic Consortium for AN (GCAN) and the Wellcome Trust Case Control Consortium 3 (WTCCC3). Individual association analyses were conducted in each stratum and meta-analyzed across all 15 discovery data sets. Seventy-six (72 independent) single nucleotide polymorphisms were taken forward for in silico (two data sets) or de novo (13 data sets) replication genotyping in 2677 independent AN cases and 8629 European ancestry controls along with 458 AN cases and 421 controls from Japan. The final global meta-analysis across discovery and replication data sets comprised 5551 AN cases and 21 080 controls. AN subtype analyses (1606 AN restricting; 1445 AN binge-purge) were performed. No findings reached genome-wide significance. Two intronic variants were suggestively associated: rs9839776 (P=3.01 × 10(-7)) in SOX2OT and rs17030795 (P=5.84 × 10(-6)) in PPP3CA. Two additional signals were specific to Europeans: rs1523921 (P=5.76 × 10(-)(6)) between CUL3 and FAM124B and rs1886797 (P=8.05 × 10(-)(6)) near SPATA13. Comparing discovery with replication results, 76% of the effects were in the same direction, an observation highly unlikely to be due to chance (P=4 × 10(-6)), strongly suggesting that true findings exist but our sample, the largest yet reported, was underpowered for their detection. The accrual of large genotyped AN case-control samples should be an immediate priority for the field.

Abstract
Autophagy, a lysosomal catabolic pathway for long-lived proteins and damaged organelles, is crucial for cell homeostasis, and survival under stressful conditions. During starvation, autophagy is induced in numerous organisms ranging from yeast to mammals, and promotes survival by supplying nutrients and energy. In the early neonatal period, when transplacental nutrients supply is interrupted, starvation-induced autophagy is crucial for neonates' survival. In adult animals, autophagy provides amino acids and participates in glucose metabolism following starvation. In patients with anorexia nervosa, autophagy appears initially protective, allowing cells to copes with nutrient deprivation. However, when starvation is critically prolonged and when body mass index reaches 13 kg/m(2) or lower, acute liver insufficiency occurs with features of autophagic cell death, which can be observed by electron microscopy analysis of liver biopsy samples. In acetaminophen overdose, a classic cause of severe liver injury, autophagy is induced as a protective mechanism. Pharmacological enhancement of autophagy protects against acetaminophen-induced necrosis. Autophagy is also activated as a rescue mechanism in response to Efavirenz-induced mitochondrial dysfunction. However, Efavirenz overdose blocks autophagy leading to liver cell death. In conclusion, in acute liver injury, autophagy appears as a protective mechanism that can be however blocked or overwhelmed.

Abstract
In this qualitative study, we aimed to investigate work demands experienced by health-care workers in an adult eating disorder inpatient service. We also aimed to investigate the use of social support and job satisfaction in this setting. Twelve health-care workers from an eating disorder inpatient ward, including nurses, health-care support workers, and occupational therapists, participated in semistructured interviews. Interviews were transcribed verbatim and analysed using thematic analysis. A number of work demands were discussed relating to therapeutic care, physical care, and organizational demands. Most participants discussed social support at work as being highly valuable, formally and informally, whereas external support was viewed as less important. Despite the challenges of caring for patients with eating disorders, the majority of participants reported good patient-related job satisfaction, but poor job satisfaction in relation to organizational factors. Eating disorder inpatient care is complex and demanding, necessitating effective teamwork, communication, and support systems among health-care workers. Interventions should be developed to target barriers to care, including time constraints, administrative workload, and insufficient allocation of staff.

Abstract
OBJECTIVE Cardiac damage is a major complication of anorexia nervosa (AN). The present study evaluated the prevalence of myocardial damage in patients with AN by cardiac magnetic resonance imaging (CMR). METHOD This study was cross-sectional and observational. Forty consecutive female patients with a diagnosis of AN and 28 healthy female subjects were evaluated from January 2007 to 2011 at the Department of Psychiatry (University of Istanbul, Istanbul, Turkey). Following enrollment in the study, participants underwent a cardiac evaluation, a physical examination, a standard electrocardiogram (ECG), an echocardiography and a CMR. RESULTS Body weight, body mass index and heart rate values were lower in patients with AN than in the control group. When compared with control groups, patients with AN showed reduced left ventricular mass with normal systolic function. Compared to control subjects, patients with AN had higher prevalence of pericardial effusion (30% in the AN group, 4% in the control group, p = .005) and mitral valve prolapses (23% in the AN group, 4% in the control group, p = .03). Myocardial fibrosis (detected as late gadolinium enhancement on CMR) was found in 23% of patients with AN. Myocardial fibrosis was not detected in any control subject (p = .007). CONCLUSION A strong association was found between myocardial fibrosis and AN. Cardiac damage of myocardial fibrosis in asymptomatic patients with AN can be found by CMR examination.

Abstract
OBJECTIVE Eating disorders, in particular anorexia nervosa (AN), are associated with cardiovascular complications and risk of arrhythmias. In a recent published study, it was found that patients with eating disorders, especially those affected by bulimia nervosa (BN) and a history of AN have abnormal late ventricular potentials (LPs). LPs are electrocardiographic markers used in detecting abnormal depolarization and increased risk of arrhythmias. Given the paucity of knowledge regarding the affects of eating disorders on cardiac depolarization, our aim was to further explore LPs in patients with eating disorders. METHOD The study group included 30 hospitalized patients with eating disorders (14 with AN, 10 with BN with no history of AN, and 6 with BN and history of AN). Signal averaged electrocardiography was conducted on all patients using the Frank corrected orthogonal lead system. RESULTS No patient with either eating disorder tested positive for LPs. DISCUSSION Hospitalized patients with eating disorders, medically monitored and treated for several weeks, had normal serum electrolytes, started to normalize their weight, and did not appear to be prone to arrhythmias associated with abnormal depolarization. The prognostic significance of LPs in risk stratification of patients with eating disorders should be further evaluated by large cohort studies and longer follow-up studies.

Abstract
UNLABELLED Abstract Objective: Psychological stress and inadequate coping skills have been hypothesized to play important roles in the etiology of disordered eating. This paper reviews the empirical evidence which has emerged regarding the proposed relationships among stress. coping skills and various forms of disordered eating. METHOD A search of psychological and medical databases was conducted to identify studies examining life events, and other types of psychological stress and coping strategies, in relation to the onset of disordered eating. RESULTS Despite methodological limitations such as the use of non-representative samples and retrospective methodologies, evidence of relationships between stress. coping and disordered eating was obtained in the majority of studies reviewed. DISCUSSION The implications of these findings am discussed and suggestions for future research, including the utilization of longitudinal. prospective studies, am presented.

Abstract
UNLABELLED A critical review of the literature was conducted to provide answers to three questions: firstly, are we facing a national and/or international epidemic of anorexia nervosa (AN) as claimed in the media by certain professionals? Secondly, is AN simply an ordinary crisis of adolescence? Thirdly, is it a pathology that solely affects the higher socio-professional categories? METHOD A Medline search was conducted and backed up by a manual search to find all the studies or literature reviews published on prevalence, incidence rates, outcomes, morbidity and mortality in AN and its links with social class, covering the period 2000-2011. RESULTS The differing methodologies of the studies on these themes have a considerable impact on the interpretation of results. For each indicator retained, the results observed in the different studies are detailed and commented in the light of these differences. The prevalence of AN in women aged 11 to 65 in non-clinical population ranges from 0 to 2.2 %. It varies in particular with the age of the studied subjects, the measurements used, and the definition criteria for AN. Among men, the lifetime prevalence is around 0.3%. The marked disparities in incidence rates observed are related to the nature of the samples considered: subjects consulting in hospital, whether in a specialised department or in any department, those consulting general practitioners (GPs), or subjects from general population samples recruited in different surveys (girls in schools for example). The incidence of female cases is low in general medicine or specialised consultation in town (whatever the speciality): from 4.2 and 8.3/100,000 individuals per year. It is much higher in the general population, ranging from 109 to 270/100,000 individuals per year. In fact, the studies reporting variations in the incidence of AN were conducted on samples from clinical populations in certain countries (United States and United Kingdom). They are probably more a reflection of variations in detection rates and use of healthcare, than of variations in the incidence in the general population. The mean duration of AN appears shorter in the general population than in clinical populations. On average, 47% of the individuals treated for AN recovered, 34% improved, 21% had a chronic eating disorder, and 5% died. The outcome is better for subjects treated during adolescence. Mortality is frequently expressed in crude mortality rate (CMR), which is not very informative on account of the heterogeneous natures of the cohorts followed; only the studies reporting standardised mortality rate (SMR) are informative. AN appears as having one of the highest mortality rates among psychiatric pathologies. Mortality varies according to the population considered. Rates observed are 6.2 to 10.6 times greater than that observed in the general population for a follow-up duration ranging respectively from 13 to 10 years. It is lower for longer follow-up periods, only 3.7 times more frequent than in the general population for follow-up periods of 20 to 40 years. It appears lower for subjects treated before the age of 20. The main causes of death are eating disorder complications, suicide and cancer. One review of the literature concluded in the absence of any significant link between this pathology and social class. DISCUSSION There is nothing in the incidence and prevalence data to back up the notion of a recent "epidemic" of AN. AN is not simply a crisis of adolescence: morbidity and mortality are considerable in this pathology. The relationship between AN and social class is not established.

Abstract
Simon Baron-Cohen pioneered the idea that different brain types evolved to process information in gender specific ways. Here we expand this approach to looking at eating disorders as a byproduct of the extreme female brain. The incidence of eating disorders is higher among females, and recent findings show that hormones may play a role in eating disorders. We present new evidence from four studies that both an empathizing bias and hyper-mentalizing (as measures of the extreme female brain; EFB) are related to disordered eating and negative evaluation anxiety in women. We also advance the novel hypothesis that concerns about animal welfare (a unique expression of the EFB) may account for the relationship between vegetarianism and eating disorders.

Abstract
Anorexia nervosa is a common psychiatric disorder that disproportionately affects adolescents and young adults and is associated with high rates of morbidity and mortality. Anorexia nervosa can affect the kidney in numerous ways, including increased rates of acute kidney injury and chronic kidney disease, electrolyte abnormalities, and nephrolithiasis. Additionally, the diagnosis and treatment of anorexia nervosa-associated kidney diseases are challenging, reflecting complications such as refeeding syndrome, as well as the limitations of serum creatinine level in this population to estimate kidney function and the psychosocial challenges inherent with treating systemic manifestations of psychiatric conditions. In this review, we discuss kidney diseases and kidney-associated conditions that occur in individuals with anorexia nervosa, summarizing many of the challenges in treating patients with this disease.

Abstract
Eating disorders are usually associated with an increased risk of premature death with a wide range of rates and causes of mortality. “Sudden death” has been defined as the abrupt and unexpected occurrence of fatality for which no satisfactory explanation of the cause can be ascertained. In many cases of sudden death, autopsies do not clarify the main cause. Cardiovascular complications are usually involved in these deaths. The purpose of this review was to report an update of the existing literature data on the main findings with respect to sudden death in eating disorders by means of a search conducted in PubMed. The most relevant conclusion of this review seems to be that the main causes of sudden death in eating disorders are those related to cardiovascular complications. The predictive value of the increased QT interval dispersion as a marker of sudden acute ventricular arrhythmia and death has been demonstrated. Eating disorder patients with severe cardiovascular symptoms should be hospitalized. In general, with respect to sudden death in eating disorders, some findings (eg, long-term eating disorders, chronic hypokalemia, chronically low plasma albumin, and QT intervals >600 milliseconds) must be taken into account, and it must be highlighted that during refeeding, the adverse effects of hypophosphatemia include cardiac failure. Monitoring vital signs and performing electrocardiograms and serial measurements of plasma potassium are relevant during the treatment of eating disorder patients.

Abstract
OBJECTIVE Elucidation of clinically relevant subtypes has been proposed as a means of advancing treatment research, but classifying anorexia nervosa (AN) patients into restricting and binge-eating/purging types has demonstrated limited predictive validity. This study aimed to evaluate whether an approach to classifying eating disorder patients on the basis of comorbid personality psychopathology has utility in predicting treatment response and readmission in patients with AN. METHOD Data were collected from 154 AN patients (M [SD] age = 25.6[9.4] years; 95.5% female; 96.8% Caucasian) at admission, discharge, and 3 months postdischarge from intensive treatment. Latent profile analysis of personality traits assessed at admission was performed to classify participants into personality subtypes, which were then used to predict outcomes at discharge and risk of readmission. RESULTS The best fitting model identified 3 personality subtypes (undercontrolled, overcontrolled, low psychopathology) that contributed significantly to multivariate models predicting study outcomes. Undercontrolled patients were more likely to have a poor outcome at discharge than overcontrolled (OR = 3.56, p = .01) and low psychopathology patients (OR = 11.23, p < .001). Undercontrolled patients also had a greater risk of discharge against medical advice (HR = 2.08, p = .02) and readmission than overcontrolled patients (HR = 3.76, p = .009). Binge-eating/purging versus restricting subtypes did not predict discharge against medical advice or readmission in the multivariate models. CONCLUSIONS Findings support the clinical utility of personality subtypes in AN. Future work is needed to identify mechanisms that explain diminished treatment response in undercontrolled patients and to develop interventions for this high-risk group.

Abstract
Anorexia nervosa is a serious mental illness that affects women and men of all ages. Despite the gravity of its chronic morbidity, risk of premature death, and societal burden, the evidence base for its treatment-especially in adults-is weak. Guided by the finding that family-based interventions confer benefit in the treatment of anorexia nervosa in adolescents, we developed a cognitive-behavioral couple-based intervention for adults with anorexia nervosa who are in committed relationships that engages both the patient and her/his partner in the treatment process. This article describes the theoretical rationale behind the development of Uniting Couples in the treatment of Anorexia nervosa (UCAN), practical considerations in delivering the intervention, and includes reflections from the developers on the challenges of working with couples in which one member suffers from anorexia nervosa. Finally, we discuss future applications of a couple-based approach to the treatment of adults with eating disorders.

Abstract
Anorexia nervosa (AN) is an eating disorder with somatic complications. The aim of the study was to analyse echocardiographic abnormalities in patients with AN at initial examination and after weight restoration. A total of 173 consecutively admitted adolescents (aged 12-17 years), diagnosed with DSM-IV AN (307.1) were evaluated in a child and adolescent psychiatric department of a major university hospital from December 1997 to August 2008. In addition, 40 healthy adolescents of the same age with normal weight were examined. In patients with AN, 34.7% had a pericardial effusion (PE) which was clinically silent. In contrast, none of the controls presented with PE (p < 0.001). No differences across AN subtypes were observed. Patients with PE showed significantly lower body mass index (BMI) (p = 0.016) than patients without PE. They had more prominent low-T3 syndrome (p = 0.003) and longer duration of hospitalisation (p = 0.008) after controlling for BMI at admission. Remission of PE was observed in 88% of the patients after weight restoration. Left ventricular end-diastolic and end-systolic dimensions in AN were significantly lower than in controls (p < 0.001). There were no differences in interventricular septum thickness, posterior wall thickness and fractional shortening. This report indicates that adolescents with AN show cardiac abnormalities in comparison to healthy young women. Furthermore, PE is a frequent cardiac complication in patients with AN and it is associated with BMI, low T3 serum levels and duration of hospitalisation.

Abstract
Anorexia nervosa (AN) is a mental illness with high mortality that most commonly afflicts adolescent female individuals. Clinical symptoms include chronic food refusal, weight loss and body image distortions. We carried out a genome-wide association study on 1033 AN cases and 3733 pediatric control subjects, all of whom were of European ancestry and were genotyped on the Illumina HumanHap610 platform (Illumina, San Diego, CA, USA). We confirmed that common single-nucleotide polymorphisms (SNPs) within OPRD1 (rs533123, P=0.0015) confer risk for AN, and obtained suggestive evidence that common SNPs near HTR1D (rs7532266, P=0.04) confer risk for restricting-type AN specifically. However, no SNPs reached genome-wide significance in our data, whereas top association signals were detected near ZNF804B, CSRP2BP, NTNG1, AKAP6 and CDH9. In parallel, we performed genome-wide analysis on copy number variations (CNVs) using the signal intensity data from the SNP arrays. We did not find evidence that AN cases have more CNVs than control subjects, nor do they have over-representation of rare or large CNVs. However, we identified several regions with rare CNVs that were only observed in AN cases, including a recurrent 13q12 deletion (1.5 Mb) disrupting SCAS in two cases, and CNVs disrupting the CNTN6/CNTN4 region in several AN cases. In conclusion, our study suggests that both common SNPs and rare CNVs may confer genetic risk to AN. These results point to intriguing genes that await further validation in independent cohorts for confirmatory roles in AN.

Abstract
BACKGROUND To our knowledge, changes in steroid metabolism in subjects with anorexia nervosa (AN) after weight gain have not been elucidated. OBJECTIVE We characterized urinary steroid excretion and metabolism in AN patients and investigated the effects of refeeding. DESIGN In an intervention study, we recruited 7 women with life-threatening weight loss upon admission and after a median [interquartile range (IQR)] of 95 d (88-125 d) of intensive refeeding; 15 age-matched women were recruited as control subjects. The major urinary metabolites were quantified in 24-h collections by capillary gas chromatography. A single examiner measured weights, heights, and skinfold thicknesses. RESULTS The median (IQR) age of patients was 24 y (21-26 y), and the duration of AN was 4.0 y (3.3-8.0 y). Body mass index (BMI; in kg/m(2)) increased from 12.8 (12.7-13.1) to 18.6 (18.0-19.6) after refeeding (P < 0.0001). Steroid values [median pre-, post-refeeding (P value)] were as follows: androgen metabolites [472, 1017 μg/24 h (0.93)], cortisol metabolites [1960, 3912 μg/24 h (0.60)], and ratios of androsterone (5α)/etiocholanolone (5β) [0.28, 0.63 (<0.001)], 5α-/5β-tetrahydrocortisol [0.20, 0.48 (0.02)], tetrahydrocortisols/tetrahydrocortisone [0.87, 0.61 (0.09)], 20-hydroxy-/20-oxocortisol metabolites [0.29, 0.47 (0.01)], and 20α-/20β-reduced cortisol metabolites [1.18, 1.89 (≥1.00)]. BMI change was positively correlated with 5α-/5β-tetrahydrocortisol (r = 0.95, P < 0.001). Before refeeding, the following metabolites were lower in patients than in control subjects: androsterone, 5α-tetrahydrocortisol, α-cortolone and α-cortol, 5α-/5β-tetrahydrocortisol, androsterone/etiocholanolone, and 20-hydroxy/20-oxocortisol (all P < 0.05). After refeeding, all steroid metabolites in patients were at concentrations that were comparable with those in control subjects. CONCLUSIONS Significant changes in urine steroid-metabolite excretion occurred upon starvation, which were reversed upon refeeding. For cortisol, there were decreases in 5α-/5β-tetrahydrocortisol and 20-hydroxy-/20-oxometabolites; for androgen, there was a decrease in androsterone/etiocholanolone.

To investigate the prefrontal hemodynamic response during a cognitive task in childhood anorexia nervosa (AN), we measured regional cerebral blood volume changes in terms of changes in hemoglobin concentrations [Hb], using near-infrared spectroscopy (NIRS). Sixteen females with AN (mean age 14.2 years old) and 12 age-matched healthy female control subjects (mean age 14.3 years old) participated in this study. Waveform patterns for [Hb] during the word fluency task differed between the two groups, although their task performances showed no significant difference. In the control group, the [total-Hb] and [oxy-Hb] immediately increased and the [deoxy-Hb] immediately decreased after the beginning of the task and gradually reached the baseline level after the end of the task. The patients with AN were consistently characterized by an unchanged or less fluctuating response pattern of [total-Hb], [oxy-Hb] and [deoxy-Hb] during the task and rest periods. In the AN group, subjects with higher Eating Attitudes Test (EAT-26) scores showed higher [oxy-Hb] during the task. On the other hand, in the control group, subjects with higher EAT-26 scores showed lower [oxy-Hb] during the task. The grand waveforms of each [Hb] during a motor activation task, which was applied as a control task, did not differ significantly between two groups. The different prefrontal hemodynamic responses might indicate that AN subjects might apply fewer brain circuits or fewer neurons per circuit during cognitive tasks and might use different brain circuits in relation to their preoccupation with eating behaviors.

Abstract
Introduction Liver injury is a frequent complication associated with anorexia nervosa, and steatosis of the liver is thought to be the major underlying pathology. However, acute hepatic failure with transaminase levels over 1000 IU/mL and deep coma are very rare complications and the mechanism of pathogenesis is largely unknown. Case presentation A 37-year-old Japanese woman showed features of acute liver failure and hepatic coma which were not associated with hypoglycemia or hyper-ammonemia. Our patient's consciousness was significantly improved with the recovery of liver function and normalization of transaminase levels after administration of nutritional support. Conclusions Our case report demonstrates that transaminase levels had an inverse relationship with the consciousness of our patient, although the pathogenesis of coma remains largely unknown. This indicates that transaminase levels can be one of the key predictors of impending coma in patients with anorexia nervosa. Therefore, frequent monitoring of transaminase levels combined with rigorous treatment of the underlying nutritional deficiency and psychiatric disorder are necessary to prevent this severe complication.

Abstract
OBJECTIVE The aim of the present study was to evaluate the effects of a short-term oral L-arginine treatment on platelet NO production, intracellular calcium concentration, iNOS and eNOS expression, in AN patients. METHOD Forty outpatients belonging to restricting subtype and 40 normal participants age and sex matched were enrolled in the study. RESULTS NO production was significantly elevated in the platelets from AN patients compared with controls while [Ca(2+)](i) was significantly decreased in patients with respect to controls. Western blot analysis demonstrated that iNOS isoform was more pronounced in the cell lysates from AN patients than controls. After supplementation with L-arginine, both NO production and [Ca(2+)](i) seem to return to control levels, suggesting a probable recovery of their metabolisms. The same was found after western blot analysis of NOS expression. DISCUSSION The results here proposed can be considered highly indicative of a positive effect of L-arginine supplementation on platelet NO production in AN patients.

Abstract
There is strong and consistent evidence that eating disorders are prevalent in sport and especially in weight sensitive sports such as endurance, weight category and aesthetic sports as well as jumping events. These illnesses are not only common but lead to significant physical and psychological morbidity and impaired performances.Sports organizations, and by extension the professionals whose job it is to help and support athletes, have important roles in dealing with these conditions. Preventative practices can be adopted if there is an understanding of how the sports environment contributes to the development of eating disorders. Some disorders can be difficult to detect especially in a sports environment and simple screening instruments are available. Athletes may also need help to access appropriate treatment whilst they are recovering.In many sports prevention, screening and support programs have been developed for a variety of medical conditions or sportsrelated injuries. Similar programs should be developed for eating disorders.

Abstract
Anorexia nervosa, a syndrome most commonly affecting young women, is characterized by weight less than 85% of weight that is considered normal for that persons age and height, distorted body image, and fear of becoming obese, and its mortality is up to 9%. We present a case of a 33-year-old woman with a 9-year history of anorexia nervosa. She admitted to our institution with decreased mentality, and her body mass index was 11.5 kg/m2 of the time admission. Initial aminotransferase level was severely elevated, but it was normalized solely with improved nutrition and weight gain. Five and sixteen days after the admission urinary tract infection and elevation of pancreatic enzymes occurred. They were successfully treated with antibiotics and nutritional support. Fifty seven days after the admission, she discharged. We report a case of acute hepatitis and pancreatitis treated with nutritional rehabilitation in a patient with severe anorexia nervosa for the first time in Korea.

Abstract
Anorexia nervosa is an eating disorder characterized by the avoidance of food intake, which usually leads to a weight loss. Cardiac co-morbility is common and we can find sometimes a mass loss from the left ventricle, which can be seen by echocardiography. But the commonest complications are rhythm variations, typically bradycardia with a prolonged QT interval in up to a 40% of the cases, which altogether elevates ventricular tachycardia and sudden death risk. We present the case of a male who was diagnosed with anorexia nervosa and developed asthenia, a long QT interval and also a severe both hypokalaemia and hypomagnesaemia. We intend to discuss the pathogenic paths as well as prophylactic and therapeutic measures to this potentially-lethal pathology.

Abstract
OBJECTIVE Critical first steps in the treatment of anorexia nervosa (AN) include re-nutrition and weight restoration, both highly anxiety provoking for patients. We explored the impact of progressive muscle relaxation (PMR), guided imagery (GI), self-directed relaxation (SR), and control (C) on reducing postprandial anxiety in 64 females with AN. METHOD Participants began the study upon hospital admission. They received relaxation training after lunch for 15 days. Pre- and post-session anxiety and treatment acceptability ratings were made daily. RESULTS Although all conditions improved relaxation and decreased anxiety, feelings of fullness, and thoughts about weight, the three active conditions significantly reduced anxiety and increased relaxation more than C (p < .0001). Participants significantly enjoyed the three active treatments, were more likely to recommend them to a friend, and were more likely to use either PMR or GI again versus C (p < .0001). CONCLUSION Relaxation may be a valuable component for reducing postprandial anxiety in AN.
