Anorexia nervosa and the long-term risk of mortality in women

Practice Assessment Tool for the Care of Patients With Eating Disorders

Eating disorders are characterized by significant disturbances in eating patterns associated with negative attitudes toward one's body, weight, and shape. They are associated with an increased risk of mortality and morbidity as well as significant health, economic, and psychosocial burdens. Additionally, individuals with eating disorders often hesitate to seek treatment and symptoms may be difficult to ascertain without structured assessment. The American Psychiatric Association Practice Guideline for the Treatment of Patients With Eating Disorders aims to enhance knowledge and increase the appropriate use of interventions for eating disorders, including anorexia nervosa, bulimia nervosa, and binge-eating disorder, thereby improving the quality of care and treatment outcomes. To this end, this evidence-based Performance in Practice tool can facilitate the implementation of a systematic approach to practice improvement for the care of individuals with eating disorders. This practice assessment activity can also be used in fulfillment of Continuing Medical Education and ABPN Continuing Certification, Improvement in Medical Practice.

Improvement in depressive symptoms in a patient with severe and enduring anorexia nervosa and comorbid major depressive disorder using psychotherapy-assisted IV ketamine : a case report

BACKGROUND

Anorexia nervosa is a life-threatening psychiatric illness with a high mortality rate and limited treatment options. This illness is frequently comorbid with major depressive disorder, leading to additional obstacles in patient quality of life, and increasing the mortality rate further due to risk of suicide. Ketamine, a competitive N-methyl-D-aspartate receptor antagonist, has been shown to be beneficial in depression given its effects on neuroplasticity. There are few cases in the literature describing ketamine use in patients with eating disorders, and even fewer that describe psychotherapy-assisted ketamine use in this patient population. We present the case of a 33-year-old woman with a history of severe and enduring anorexia nervosa and comorbid major depressive disorder who we treated safely with ketamine-assisted psychotherapy using intravenous ketamine in a general hospital setting.

CASE PRESENTATION

Our patient is a 33-year-old woman with past psychiatric history of severe and enduring anorexia nervosa and major depressive disorder with comorbid psychiatric and medical conditions who presented to the hospital due to malnutrition. She had an extensive psychiatric history as well as multiple medical hospitalizations due to her eating disorder. She had tried numerous psychiatric treatments, including antidepressants, mood stabilizers, antipsychotics, electroconvulsive therapy, and multiple types of therapies without significant improvement in symptoms. She agreed to try ketamine for treatment-resistant depression and received it intravenously for seven sessions in a closely monitored setting, and simultaneously engaged in acceptance and commitment therapy during sessions. She demonstrated increased cognitive flexibility, disappearance of suicidal ideation, and reduction in Beck Depression Inventory Scores.

CONCLUSIONS

Our case is unique in that it demonstrates the successful usage of ketamine-assisted psychotherapy in a hospital setting with severe and enduring anorexia nervosa and comorbid major depressive disorder. Her body mass index was profoundly low at 13, whereas the lowest documented in the literature was 16.9. This case shows that ketamine-assisted psychotherapy may be a promising treatment modality for patients with anorexia nervosa with co-morbid depression who have failed other interventions.

Adolescent activity-based anorexia has a substantial and prolonged impact on social behavior in young adult female rats

Activity-based anorexia (ABA) is a rodent model of anorexia nervosa (AN) that induces several key components of AN, including voluntary reduction in food intake, reduced body weight, hyperactivity, and alterations to the hypothalamic-pituitary-adrenal (HPA) axis. Previous research has demonstrated persistently increased anxiety-like behavior in the elevated plus maze (EPM), a test measuring avoidance of novel and open areas in adult female rats that experienced ABA during adolescence and are weight-restored in adulthood. Whether the same behavioral effects of two bouts of adolescent ABA emerge in response to different anxiety-provoking stimuli, however, has not been explored. We used the social partition (SP), novelty suppressed feeding (NSF), marble burying, and EPM tests to explore whether two bouts of adolescent ABA have persistent effects on anxiety-like behavior in weight restored young adult female rats. One-way ANOVA analyses revealed that female rats that experienced two bouts of ABA during adolescence had increased anxiety-like behavior in the EPM and SP tests in young adulthood following weight restoration compared with controls. These data demonstrate that the enduring behavioral effects of two bouts of adolescent ABA are specific to particular anxiety-provoking stimuli and suggest that adolescent ABA has enduring effects on social relationships.

A qualitative assessment of provider-perceived barriers to implementing family-based treatment for anorexia nervosa in low-income community settings

BACKGROUND

Family-based treatment (FBT) is a front-line empirically supported intervention for adolescent anorexia nervosa, but it is often inaccessible to families from lower income backgrounds, as it is most typically available in specialty research and private practice settings. In preparation for a pilot trial of FBT delivered in the home setting, this study qualitatively examined provider perceptions of implementing FBT in lower-income communities.

METHODS

Eating disorder clinicians working in community clinics (therapists, medical doctors, dietitians, and social workers; n = 9) were interviewed about their experiences using FBT. Interview transcripts were analyzed both deductively, using an approach consistent with applied thematic analysis, and inductively, using the Replicating Effective Programs implementation framework, to examine barriers to FBT implementation.

RESULTS

Prevailing themes included concern about the time and resources required of caregivers to participate in FBT, which may not be feasible for those who work full time, have other caregiving demands, and/or lack family support. Psychosocial problems outside of the eating disorder, such as food insecurity, other untreated mental health concerns (in themselves or other family members), or externalizing behaviors on the part of the adolescent, were also discussed as barriers, and participants noted that the lack of cohesive treatment teams in the community make it difficult to ensure continuity of care.

CONCLUSION

Findings from this qualitative study indicate the need to address systemic socioeconomic barriers to improve the efficacy of implementation of FBT in the community and to understand how provider perceptions of these barriers influence their uptake of FBT.

An examination of adults with atypical anorexia nervosa at admission to treatment at higher levels of care: An attempt to increase diagnostic clarity

OBJECTIVE

Anorexia nervosa (AN) is a serious illness with a high mortality rate and multiple physiological complications. The vague definition of atypical AN allows for subjective interpretation. This retrospective study aimed to focus future research on the operational definition of atypical AN by examining four factors associated with atypical AN at admission to higher level of care treatment.

METHODS

Adults with atypical AN (n = 69) were examined within sample analyses among four groups: (1) >10% versus ≤10% weight loss; (2) weight loss within the previous 3 months versus >3 months; (3) engaging in purging behaviors versus absence of purging behaviors; and (4) endorsing versus not endorsing significant cognitive aspects of AN.

RESULTS

Patients with atypical AN endorsed elevated ED cognitions on the Eating Disorder Examination-Questionnaire and depressive symptoms; a lack of association was found between weight loss severity and weight loss time frame with depressive symptoms, eating concern, and restraint. Purging behavior was associated with a higher expected body weight percentage (%EBW) and dietary restraint, while greater AN cognitions were associated with a higher EBW and weight loss percentage. Few patients demonstrated bradycardia, hypophosphatemia, or amenorrhea.

DISCUSSION

This study demonstrated the severity of ED cognitions and depressive symptoms in this atypical AN sample and provided directions for future studies in the nosology of atypical AN. It may be important to distinguish between individuals with atypical AN who are purging and those who are not. Atypical AN was associated with a low frequency of physiological disturbances.

PUBLIC SIGNIFICANCE

This study provides further clarification regarding the operational definition of atypical AN; currently, a constellation of symptoms under Other Specified Feeding or Eating Disorders. This study was consistent with previous research in reporting severe eating disorder cognitions in adults with atypical AN, and noted the potential importance of distinguishing a purging distinction. A minority of patients in this study had physiological impairments.

[New aspects in etiology and treatment of adolescent anorexia nervosa-a postulated bio-psycho-social model and the impact of the COVID-19 pandemic]

Anorexia nervosa is one of the most frequent chronic disorders of adolescence associated with a high mortality. During the COVID-19-pandemic, the number of hospitalized children and adolescents with anorexia nervosa significantly increased. This article outlines new research findings to decode the etiology of this serious disorder, especially a genetic disposition and changes of metabolism. Against the background of increasing rates during the COVID-19 pandemic, the importance of the gene-environment interaction is discussed, and new treatment forms are described. Besides the development of new biological treatment strategies, there is also some important progress in psychotherapeutic interventions. Carers should always be integrated when treating children and adolescents with anorexia nervosa, which is especially emphasized in the new "home treatment" setting. The new concept of anorexia nervosa as a metabo-psychiatric disorder gives us hope for new research ideas and treatment strategies in this often-debilitating disorder of childhood and adolescence.

Transitions from child and adolescent to adult mental health services for eating disorders: an in-depth systematic review and development of a transition framework

BACKGROUND

Eating disorders (EDs) peak in mid-to-late adolescence and often persist into adulthood. Given their early onset and chronicity, many patients transition from child and adolescent mental health services (CAMHS) to adult mental health services (AMHS) for ongoing, speciality ED care. This transition typically occurs at 18 years of age, when important biological, psychosocial, and vocational changes take place. Thus, smooth and effective transitions are paramount for ensuring service continuity, as well as reducing the risk of ED relapse and premature death. Here, we synthesized evidence on transitions from CAMHS to AMHS for young people with EDs, aiming to inform future research, clinical practice, and healthcare policy.

METHODS

A systematic review of the literature was conducted. This adhered to PRISMA guidelines. PubMed, Embase, and Scopus electronic databases were queried from inception to December 3, 2023. Leveraging the PICOS framework, study eligibility was evaluated in the qualitative synthesis. Data regarding methodology, analytic approach, and associated outcomes were then extracted. The quality of evidence was examined using critical appraisal tools. Finally, concept mapping was applied to organize findings into a transition framework.

RESULTS

The search returned 76 articles. Of these, 14 were included in the final review. Articles were grouped into 'qualitative' (n = 10), 'cross-sectional' (n = 2), and 'longitudinal cohort' (n = 2) studies based on research design. Overall, ED transitions were complex, multifaceted, and challenging for patients, caregivers, and providers alike. This resulted from an interplay of temporal- (e.g., timing of ED onset and transition), stakeholder- (e.g., patient ambivalence towards recovery) and systemic- (e.g., differences between services) related factors. Most studies were of moderate-to-high quality. Findings informed the development of five transition strategies designed to facilitate effective transfers across ED care: Timely talks, Readiness, Inclusion, Preparation, and Synergy (TRIPS).

CONCLUSIONS

Transitions from CAMHS to AMHS appear problematic for young people with EDs and other involved stakeholders. The field stands to benefit from TRIPS, an actionable, evidence-based framework that aims to alleviate challenges of transitioning and subsequently improve ED trajectories. As a logical next step, future work should empirically test the TRIPS framework, exploring its predictive utility and clinical value.

National Clinical Programme for Eating Disorders: a pragmatic review of a new national eating disorder service in Ireland

OBJECTIVE

The Health Service Executive National Clinical Programme for Eating Disorders (NCPED) launched a Model of Care for Eating Disorder Services in Ireland in 2018. Currently, one adult and two child and adolescent eating disorder services are operational out of a total of sixteen recommended. The three objectives of this paper are to describe the early (1) referral pattern, (2) level of service activity and (3) the level of service user satisfaction.

METHOD

Monthly submitted service activity data from each service to the NCPED between March 2018 and October 2020 were retrospectively analysed. One hundred and fifty-nine carers and service users completed an experience of service questionnaire (ESQ). A descriptive analysis of referral pattern, level of service activity and ESQ was performed. A thematic analysis was performed on three qualitative questions on the ESQ.

RESULTS

There was substantial referral numbers to eating disorder services by 18 months (n = 258). The main referral source was community mental health teams. The majority (n = 222, 86%) of referrals were offered an assessment. The most common age profile was 10-17 years of age (n = 120, 54.1%), and anorexia nervosa was the most common disorder (n = 96, 43.2%). ESQ results demonstrate that most service users were satisfied with their service, and the main themes were carer involvement, staff expertise, therapeutic alliance and service access.

CONCLUSIONS

This preliminary service activity and service user satisfaction data highlight several issues, including trends when setting up a regional eating disorder service, potential pitfalls of pragmatic data collection and the need for adequate information-technology infrastructure.

Plasma proteome profiling reveals metabolic and immunologic differences between Anorexia Nervosa subtypes

AIMS/HYPOTHESIS

Anorexia Nervosa (AN) is a severe psychiatric disorder of an unknown etiology with a crude mortality rate of about 5 % per decade, making it one of the deadliest of all psychiatric illnesses. AN is broadly classified into two main subtypes, restricting and binge/purging disorder. Despite extensive research efforts during several decades, the underlying pathophysiology of AN remains poorly understood. In this study, we aimed to identify novel protein biomarkers for AN by performing a proteomics analysis of fasting plasma samples from 78 females with AN (57 restrictive and 21 binge/purge type) and 70 healthy controls.

METHODS

Using state-of-the-art mass spectrometry-based proteomics technology in conjunction with an advanced bioinformatics pipeline, we quantify >500 plasma proteins.

RESULTS

Differential expression analysis and correlation of proteomics data with clinical variables led to identification of a panel of novel protein biomarkers with potential pathophysiological significance for AN. Our findings demonstrate evidence of a humoral immune system response, altered lipid metabolism and potential alteration of plasma cells in AN patients. Additionally, we stratified AN patients based on the quantified proteins and suggest a potential autoimmune nature in the restrictive subtype of AN.

CONCLUSIONS/INTERPRETATION

In summary, on top of biomarkers of AN subtypes, this study provides a comprehensive map of plasma proteins that constitute a resource for further studies of the pathophysiology of AN.

Outcomes in people with eating disorders: a transdiagnostic and disorder-specific systematic review, meta-analysis and multivariable meta-regression analysis

Eating disorders (EDs) are known to be associated with high mortality and often chronic and severe course, but a recent comprehensive systematic review of their outcomes is currently missing. In the present systematic review and meta-analysis, we examined cohort studies and clinical trials published between 1980 and 2021 that reported, for DSM/ICD-defined EDs, overall ED outcomes (i.e., recovery, improvement and relapse, all-cause and ED-related hospitalization, and chronicity); the same outcomes related to purging, binge eating and body weight status; as well as mortality. We included 415 studies (N=88,372, mean age: 25.7±6.9 years, females: 72.4%, mean follow-up: 38.3±76.5 months), conducted in persons with anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), other specified feeding and eating disorders (OSFED), and/or mixed EDs, from all continents except Africa. In all EDs pooled together, overall recovery occurred in 46% of patients (95% CI: 44-49, n=283, mean follow-up: 44.9±62.8 months, no significant ED-group difference). The recovery rate was 42% at <2 years, 43% at 2 to <4 years, 54% at 4 to <6 years, 59% at 6 to <8 years, 64% at 8 to <10 years, and 67% at ≥10 years. Overall chronicity occurred in 25% of patients (95% CI: 23-29, n=170, mean follow-up: 59.3±71.2 months, no significant ED-group difference). The chronicity rate was 33% at <2 years, 40% at 2 to <4 years, 23% at 4 to <6 years, 25% at 6 to <8 years, 12% at 8 to <10 years, and 18% at ≥10 years. Mortality occurred in 0.4% of patients (95% CI: 0.2-0.7, n=214, mean follow-up: 72.2±117.7 months, no significant ED-group difference). Considering observational studies, the mortality rate was 5.2 deaths/1,000 person-years (95% CI: 4.4-6.1, n=167, mean follow-up: 88.7±120.5 months; significant difference among EDs: p<0.01, range: from 8.2 for mixed ED to 3.4 for BN). Hospitalization occurred in 26% of patients (95% CI: 18-36, n=18, mean follow-up: 43.2±41.6 months; significant difference among EDs: p<0.001, range: from 32% for AN to 4% for BN). Regarding diagnostic migration, 8% of patients with AN migrated to BN and 16% to OSFED; 2% of patients with BN migrated to AN, 5% to BED, and 19% to OSFED; 9% of patients with BED migrated to BN and 19% to OSFED; 7% of patients with OSFED migrated to AN and 10% to BN. Children/adolescents had more favorable outcomes across and within EDs than adults. Self-injurious behaviors were associated with lower recovery rates in pooled EDs. A higher socio-demographic index moderated lower recovery and higher chronicity in AN across countries. Specific treatments associated with higher recovery rates were family-based therapy, cognitive-behavioral therapy (CBT), psychodynamic therapy, and nutritional interventions for AN; self-help, CBT, dialectical behavioral therapy (DBT), psychodynamic therapy, nutritional and pharmacological treatments for BN; CBT, nutritional and pharmacological interventions, and DBT for BED; and CBT and psychodynamic therapy for OSFED. In AN, pharmacological treatment was associated with lower recovery, and waiting list with higher mortality. These results should inform future research, clinical practice and health service organization for persons with EDs.

Psychologically informed care of patients with anorexia nervosa on an acute medical ward

Anorexia nervosa is a challenging and highly distressing illness associated with significant and often debilitating symptoms that affect the person's physical and mental well-being, as well as their wider social networks. Although some patients can make important steps in their recovery in the community, many will become significantly unwell and require medical stabilisation and refeeding in an acute medical ward as a result of significant weight loss. This article describes some of the challenges experienced by adult nurses when caring for patients with anorexia nervosa on acute medical wards and explores how the patient's distress may manifest and complicate the recovery process. The article also discusses the principles of psychologically informed care and therapeutic interactions that nurses can use to promote recovery and ensure optimal practice.

Involuntary Treatment for Child and Adolescent Anorexia Nervosa-A Narrative Review and Possible Advances to Move Away from Coercion

BACKGROUND

Children and adolescents with psychiatric disorders frequently experience hospital treatment as coercive. In particular, for patients with severe anorexia nervosa (AN), clinical and ethical challenges often arise if they do not voluntarily agree to hospital admission, often due to the ego-syntonic nature of the disorder. In these cases, involuntary treatment (IVT) might be life-saving. However, coercion can cause patients to experience excruciating feelings of pressure and guilt and might have long-term consequences.

METHODS

This narrative review aimed to summarize the current empirical findings regarding IVT for child and adolescent AN. Furthermore, it aimed to present alternative treatment programs to find a collaborative method of treatment for young AN patients and their families.

RESULTS

Empirical data on IVT show that even though no inferiority of IVT has been reported regarding treatment outcomes, involuntary hospital treatment takes longer, and IVT patients seem to struggle significantly more with weight restoration. We argue that more patient- and family-oriented treatment options, such as home treatment, might offer a promising approach to shorten or even avoid involuntary hospital admissions and further IVT. Different home treatment approaches, either aiming at preventing hospitalization or at shortening hospital stays, and the results of pilot studies are summarized in this article.

Elevated lipid class concentrations in females with anorexia nervosa before and after intensive weight restoration treatment-A lipidomics study

OBJECTIVE

To study the plasma lipidome of patients with anorexia nervosa (AN) before and after weight restoration treatment and report associations with AN subtypes and oral contraceptive pill (OCP) usage.

METHODS

Quantitative shotgun lipidomics analysis was used to study plasma lipids of 50 female patients with AN before and after weight restoration treatment and 50 healthy female controls (HC). The AN group was assessed with blood samples and questionnaires before and after weight restoration.

RESULTS

In total we quantified 260 lipid species representing 26 lipid classes of which 13 lipid class concentrations were elevated in patients with AN at admission compared with HC. Lipid classes remained elevated after weight restoration treatment of 84 days (median; interquartile range 28), and only the concentration of the ceramide lipid class increased between pre- and post-treatment (p = .03), whereas lysophosphatidylcholine (LPC, p = .02), ether-linked Phosphatidylcholine (LPCO, p = .02), and lysophosphatidylethanolamine (LPE, p = .009) decreased.

CONCLUSION

In AN, 13 out of 26 lipid class concentrations were elevated at admission and remained elevated post-treatment. Ceramides increased further between pre- and post-weight restoration treatment, which could be related to the rapid weight gain during re-nutrition. Further research is needed to elucidate the effects of weight restoration treatment on short- and long-term lipid profiles in individuals with AN.

PUBLIC SIGNIFICANCE STATEMENT

Lipidomics research can increase the understanding of AN, a complex and potentially life-threatening eating disorder. By analyzing lipids, or fats, in the body, we can identify biological markers that may inform diagnosis and develop more effective treatments. This research can also shed light on the underlying mechanisms of the disorder, leading to a better understanding of the processes involved in eating behavior.

Hypercapnia in hospitalized children and adolescents with anorexia nervosa as a predictive marker for readmission: a prospective study

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.

Timing matters: The contribution of running during different periods of the light/dark cycle to susceptibility to activity-based anorexia in rats

Individuals with anorexia nervosa (AN) exhibit dangerous weight loss due to restricted eating and hyperactivity. Those with AN are predominantly women and most cases have an age of onset during adolescence. Activity-based anorexia (ABA) is a rodent behavioral paradigm that recapitulates many of the features of AN including restricted food intake and hyperactivity, resulting in precipitous weight loss. In addition, there is enhanced sensitivity to the paradigm during adolescence. In ABA, animals are given time-restricted access to food and unlimited access to a running wheel. Under these conditions, most animals increase their running and decrease their food intake resulting in precipitous weight loss until they either die or researchers discontinue the paradigm. Some animals learn to balance their food intake and energy expenditure and are able to stabilize and eventually reverse their weight loss. For these studies, adolescent (postnatal day 33-42), female Sprague Dawley (n = 68) rats were placed under ABA conditions (unlimited access to a running wheel and 1.5 hrs access to food) until they either reached 25% body weight loss or for 7 days. 70.6% of subjects reached 25% body weight loss before 7 days and were designated susceptible to ABA while 29.4% animals were resistant to the paradigm and did not achieve the weight loss criterion. We used discrete time survival analysis to investigate the contribution of food intake and running behavior during distinct time periods both prior to and during ABA to the likelihood of reaching the weight loss criterion and dropping out of ABA. Our analyses revealed risk factors, including total running and dark cycle running, that increased the likelihood of dropping out of the paradigm, as well as protective factors, including age at the start of ABA, the percent of total running exhibited as food anticipatory activity (FAA), and food intake, that reduced the likelihood of dropping out. These measures had predictive value whether taken before or during exposure to ABA conditions. Our findings suggest that certain running and food intake behaviors may be indicative of a phenotype that predisposes animals to susceptibility to ABA. They also provide evidence that running during distinct time periods may reflect functioning of distinct neural circuitry and differentially influence susceptibility and resistance to the paradigm.

Acute liver failure and aplastic crisis due to anorexia nervosa in an adolescent girl: a case report

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.

Mortality in anorexia nervosa and bulimia nervosa: A population-based cohort study in Taiwan, 2002-2017

OBJECTIVE

To investigate natural- and unnatural-cause mortality at different follow-up time points in Taiwanese patients with anorexia nervosa (AN) and bulimia nervosa (BN).

METHOD

In this longitudinal cohort study, 330,393 patients, including 2143 patients with AN, 13,590 with BN, and 20 times as many respective non-AN and non-BN patients, were followed up for 16 years. We performed conditional Cox regression survival analysis to examine the risk of mortality in the AN and BN groups relative to the comparison group.

RESULTS

A total of 1242 patients died, including 101 and 343 patients with AN and BN, respectively. Mortality rates for AN and BN were 5.42 and 2.90 deaths per 1000 person-years, respectively. Compared with the non-AN group, the AN group had a significantly higher risk of both natural- and unnatural-cause mortality, and the BN group had a significantly higher risk of unnatural-cause mortality. Suicide was the most common cause of death, and suicide risk was significantly higher in both the AN and BN groups. All-cause mortality risk was the highest at the beginning of follow-up and markedly declined in the AN group. In the BN group, all-cause mortality risk was lower but stable at follow-up. The risk of unnatural-cause mortality remained high throughout the follow-up period for both the groups.

CONCLUSIONS

Early detection and treatment for associated physical problems in patients with AN are crucial. Regular monitoring for unnatural-cause mortality events (mainly suicide) in AN and BN over time is also crucial.

PUBLIC SIGNIFICANCE

AN had a significantly higher risk of both natural- and unnatural-cause mortality and BN had a significantly higher risk of death from unnatural causes. All-cause mortality risk was highest at the beginning of follow-up in AN, but unnatural-cause mortality risk remained high throughout the follow-up period for both groups. Our findings imply that early detection and treatment in AN and regular monitoring for unnatural-cause mortality events in AN and BN are crucial.

Mortality and care of eating disorders

INTRODUCTION

Eating disorders (EDs) are considered serious mental illnesses, with one of the highest lethality among psychiatric disorders, even though the issue of mortality due to these conditions is still controversial. The present study was aimed at comparing the mortality rate in a cohort of ED patients representative of the geographic area with that of the age and gender-matched general population of central Italy.

METHODS

Patients were enrolled between 1994 and 2018, among those attending the eating disorders treatment network of the Florence area (EDTN), which is a regional multidisciplinary treatment reference center for EDs covering the clinical population of the metropolitan Florence area (Italy). The life status of participants was determined through linkage with the Regional Mortality Registry.

RESULTS

A total of 1277 individuals with EDs were included, including 368 with Anorexia Nervosa (AN), 312 with Bulimia Nervosa (BN), and 597 individuals with Binge Eating Disorder (BED). Twenty-two patients (1.72%) died, during a median follow-up of 7.4 years. The mortality rates among ED patients did not significantly differ from that of the general population of the same age and sex with a Standardized Mortality Ratio (SMR) of 1.19, 95% CI 0.79-1.81. Only among BN patients, the mortality was significantly increased after 10 years from clinical evaluation (SMR 11.24, 95% CI 3.62-34.84).

CONCLUSION

The low mortality in EDs, compared to published studies, might be due to the EDTN treatment strategy, based on a large network which makes an integrated multidisciplinary team available for almost all the patients with EDs of the geographical area.

Causes of death in patients with a history of severe anorexia nervosa

OBJECTIVE

This study reports causes of death for a cohort of 35 patients with severe anorexia nervosa (AN), who were treated between 2012 and 2020, and descriptive information on their medical and psychological comorbidities is provided.

METHODS

Three hundred and seventy patient names were submitted to the National Death Index (NDI). The NDI reviewed whether a death certificate matching each patient's identifying information existed, and if it existed, specific causes of death were noted. The original group of 370 patients consisted of 229 individuals who had been treated voluntarily and 141 who had been treated involuntarily.

RESULTS

Thirty-five patients, from the 370 (9.4%) submitted to the NDI, with an initial diagnosis of AN, were confirmed deceased. Most (83%) were female with an average age of 38.5 years (SD:12.7) and average body mass index (BMI) of 12.8 kg/m² (SD:2.4). The total number of patients, with AN listed as a cause of death, was 24 (69%). Two patients died as a result of suicide. Twenty-eight (80%) of the patients had a specific medical disease listed as a cause of death, with the most frequent being cardiovascular, metabolic, or gastrointestinal.

CONCLUSIONS

AN is associated with a substantial risk of death from many medical causes. However, two (5.7%) of our sample died by suicide, a rate considerably lower than previously reported.

Mechanisms by which adverse childhood experiences, other traumas and PTSD influence the health and well-being of individuals with eating disorders throughout the life span

BACKGROUND

Multiple published sources from around the world have confirmed an association between an array of adverse childhood experiences (ACEs) and other traumatic events with eating disorders (EDs) and related adverse outcomes, including higher morbidity and mortality.

METHODS

In keeping with this Special Issue's goals, this narrative review focuses on the ACEs pyramid and its purported mechanisms through which child maltreatment and other forms of violence toward human beings influence the health and well-being of individuals who develop EDs throughout the life span. Relevant literature on posttraumatic stress disorder (PTSD) is highlighted when applicable.

RESULTS

At every level of the pyramid, it is shown that EDs interact with each of these proclaimed escalating mechanisms in a bidirectional manner that contributes to the predisposition, precipitation and perpetuation of EDs and related medical and psychiatric comorbidities, which then predispose to early death. The levels and their interactions that are discussed include the contribution of generational embodiment (genetics) and historical trauma (epigenetics), social conditions and local context, the ACEs and other traumas themselves, the resultant disrupted neurodevelopment, subsequent social, emotional and cognitive impairment, the adoption of health risk behaviors, and the development of disease, disability and social problems, all resulting in premature mortality by means of fatal complications and/or suicide.

CONCLUSIONS

The implications of these cascading, evolving, and intertwined perspectives have important implications for the assessment and treatment of EDs using trauma-informed care and trauma-focused integrated treatment approaches. This overview offers multiple opportunities at every level for the palliation and prevention of EDs and other associated trauma-related conditions, including PTSD.

Competency-based pre-service education for clinical psychology training in low- and middle-income countries: Case study of Makerere University in Uganda

Reducing the global treatment gap for mental health conditions in low- and middle-income countries (LMICs) requires not only an expansion of clinical psychology training but also assuring that graduates of these programs have the competency to effectively and safely deliver psychological interventions. Clinical psychology training programs in LMICs require standardized tools and guidance to evaluate competency. The World Health Organization (WHO) and UNICEF developed the “Ensuring Quality in Psychological Support” (EQUIP) platform to facilitate competency-based training in psychosocial support, psychological treatments, and foundational helping skills, with an initial focus on in-service training for non-specialists. Our goal was to design the first application of EQUIP to implement competency-based training into pre-service education for clinical psychology trainees. With Makerere University in Uganda as a case study, we outline an approach to develop, implement, and evaluate a competency-based curriculum that includes seven steps: (1) Identify core clinical psychology competencies; (2) Identify evaluation methods appropriate to each competency; (3) Determine when competency evaluations will be integrated in the curriculum, who will evaluate competency, and how results will be used; (4) Train faculty in competency-based education including conducting competency assessments and giving competency-based feedback; (5) Pilot test and evaluate the competency-based education strategy with faculty and students; (6) Modify and implement the competency-based education strategy based on pilot results; and (7) Implement ongoing evaluation of the competency-based curriculum with continuous quality improvement. This approach will be formally evaluated and established as a foundation for pre-service training in other low-resource settings.

Cerebellar tonsillar herniation in sudden death of an adolescent anorexia nervosa patient: a case report

BACKGROUND

Anorexia nervosa not only results in severe malnutrition but also carries a high risk of sudden death. Although fatal arrhythmias are the most common cause of sudden death, it is often unclear what exactly causes them. To the best of our knowledge, there have been no reports of cerebellar tonsillar herniations in patients with anorexia nervosa.

CASE PRESENTATION

A 17-year-old girl with anorexia nervosa and autism spectrum disorder was admitted to the pediatric ward for extreme weight loss. Since she refused to take oral nutrition or tube feeding, we started continuous intravenous fluids. Eight hours after admission, she suddenly went into cardiopulmonary arrest and died despite resuscitation. A postmortem autopsy revealed the unexpected findings of generalized severe cerebral edema and cerebellar tonsillar herniation.

CONCLUSION

Intracranial hypertension may need to be considered when the condition of patients with anorexia nervosa suddenly worsens during refeeding periods. Postmortem autopsy and autopsy imaging are recommended to determine the exact cause of sudden death.

LEVEL OF EVIDENCE

Level IV: Evidence obtained from multiple time series analysis such as case studies. (NB: Dramatic results in uncontrolled trials might also be regarded as this type of evidence).

What accounts for the high mortality of anorexia nervosa?

The exact medical complications, leading to the well-known high risk of death in patients with anorexia nervosa (AN), remain elusive. Such deaths are often abrupt with no satisfactory explanation. Suspected causes include cardiac QTc prolongation and, in turn, torsade de pointes (TdP). Psychotropic medications often prescribed to these patients are linked to QTc prolongation. AN is also presumed to cause heart failure due to malnutrition with increased susceptibility to QTc prolongation, and TdP, resulting in sudden cardiac death. Recent literature, however, is conflicting, and the likely cause of death may involve other cardiac abnormalities, such as low heart rate, abnormal heart rate variability, or increased QT dispersion. With an ongoing gap in research explaining the high mortality rate in AN, a compelling need to define the exact proximate causes of death in these patients remains. Because low serum potassium is the most common trigger for TdP, we postulate the early signal of sudden cardiac death, especially in patients with AN who purge, is hypokalemia. We also speculate that hypoglycemia could be a major factor in the sudden death of patients with AN as well as bradycardia or sinus arrest. A path forward to elucidate potential causes is offered.
