Psychiatric and medical comorbidities of eating disorders : findings from a rapid review of the literature
Background: Eating disorders (EDs) are potentially severe, complex, and life-threatening illnesses. The mortality rate
of EDs is signifcantly elevated compared to other psychiatric conditions, primarily due to medical complications and
suicide. The current rapid review aimed to summarise the literature and identify gaps in knowledge relating to any
psychiatric and medical comorbidities of eating disorders.
Methods: This paper forms part of a rapid review) series scoping the evidence base for the feld of EDs, conducted
to inform the Australian National Eating Disorders Research and Translation Strategy 2021–2031, funded and released
by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for English-language studies
focused on the psychiatric and medical comorbidities of EDs, published between 2009 and 2021. High-level evidence
such as meta-analyses, large population studies and Randomised Control Trials were prioritised.
Results: A total of 202 studies were included in this review, with 58% pertaining to psychiatric comorbidities and
42% to medical comorbidities. For EDs in general, the most prevalent psychiatric comorbidities were anxiety (up
to 62%), mood (up to 54%) and substance use and post-traumatic stress disorders (similar comorbidity rates up to
27%). The review also noted associations between specifc EDs and non-suicidal self-injury, personality disorders, and
neurodevelopmental disorders. EDs were complicated by medical comorbidities across the neuroendocrine, skeletal,
nutritional, gastrointestinal, dental, and reproductive systems. Medical comorbidities can precede, occur alongside or
emerge as a complication of the ED.
Conclusions: This review provides a thorough overview of the comorbid psychiatric and medical conditions cooccurring with EDs. High psychiatric and medical comorbidity rates were observed in people with EDs, with comorbidities contributing to increased ED symptom severity, maintenance of some ED behaviours, and poorer functioning
as well as treatment outcomes. Early identifcation and management of psychiatric and medical comorbidities in
people with an ED may improve response to treatment and overall outcomes
Informing the development of Australia's national eating disorders research and translation strategy : a rapid review methodology
Background Eating disorders (EDs) are highly complex mental illnesses associated with significant medical complications. There are currently knowledge gaps in research relating to the epidemiology, aetiology, treatment, burden, and outcomes of eating disorders. To clearly identify and begin addressing the major deficits in the scientific, medical, and clinical understanding of these mental illnesses, the Australian Government Department of Health in 2019 funded the InsideOut Institute (IOI) to develop the Australian Eating Disorder Research and Translation Strategy, the primary aim of which was to identify priorities and targets for building research capacity and outputs. A series of rapid reviews (RR) were conducted to map the current state of knowledge, identify evidence gaps, and inform development of the national research strategy. Published peer-reviewed literature on DSM-5 listed EDs, across eight knowledge domains was reviewed: (1) population, prevalence, disease burden, Quality of Life in Western developed countries; (2) risk factors; (3) co-occurring conditions and medical complications; (4) screening and diagnosis; (5) prevention and early intervention; (6) psychotherapies and relapse prevention; (7) models of care; (8) pharmacotherapies, alternative and adjunctive therapies; and (9) outcomes (including mortality). While RRs are systematic in nature, they are distinct from systematic reviews in their aim to gather evidence in a timely manner to support decision-making on urgent or high-priority health concerns at the national level. Results Three medical science databases were searched as the primary source of literature for the RRs: Science Direct, PubMed and OVID (Medline). The search was completed on 31st May 2021 (spanning January 2009-May 2021). At writing, a total of 1,320 articles met eligibility criteria and were included in the final review. Conclusions For each RR, the evidence has been organised to review the knowledge area and identify gaps for further research and investment. The series of RRs (published separately within the current series) are designed to support the development of research and translation practice in the field of EDs. They highlight areas for investment and investigation, and provide researchers, service planners and providers, and research funders rapid access to quality current evidence, which has been synthesised and organised to assist decision-making

We performed single-cell transcriptome, surface proteome and T and B lymphocyte antigen receptor analyses of over 780,000 peripheral blood mononuclear cells from a cross-sectional cohort of 130 patients with varying severities of COVID-19. We identified expansion of nonclassical monocytes expressing complement transcripts (CD16+C1QA/B/C+) that sequester platelets and were predicted to replenish the alveolar macrophage pool in COVID-19. Early, uncommitted CD34+ hematopoietic stem/progenitor cells were primed toward megakaryopoiesis, accompanied by expanded megakaryocyte-committed progenitors and increased platelet activation. Clonally expanded CD8+ T cells and an increased ratio of CD8+ effector T cells to effector memory T cells characterized severe disease, while circulating follicular helper T cells accompanied mild disease. We observed a relative loss of IgA2 in symptomatic disease despite an overall expansion of plasmablasts and plasma cells. Our study highlights the coordinated immune response that contributes to COVID-19 pathogenesis and reveals discrete cellular components that can be targeted for therapy
The efficacy of family treatments for adolescent anorexia nervosa in specialist versus non-specialist settings: protocol for a systematic review and meta-analysis
Exploring the early-phase implementation of digital health solutions to improve access and treatment outcomes of eating disorders within in rural and regional health services
Background: Anorexia Nervosa (AN) is a complex eating disorder with severe implications, carrying the highest mortality rate of all psychiatric illnesses. Fortunately, there are efficacious treatments available, with Family-Based Treatment (FBT) recommended as the outpatient intervention of choice for young people with AN. Treatment to protocol has relied on face-to-face delivery within specialist settings. FBT is subject to geographic, temporal, and human factors, rendering it susceptible to inequities and disruption, resulting in poorer service provision. Telehealth offers a potential solution to this problem. However, the barriers, facilitators, acceptability and effectiveness of the digital translation of evidence-based treatments from the ‘ivory tower’ of specialist clinics to ‘real world’ community health services remains unknown. Aims: The aim of the presentation is to discuss the barriers and facilitators of implementing telehealth-delivered FBT into the rural and regional mental health system. Methods: Implementation data (qualitative and quantitative) will be analysed to understand the barriers and facilitators of the early-implementation phase. Results: This presentation will discuss the barriers and facilitators during the early implementation of telehealth-delivered FBT within rural health services. Conclusions: If digitally delivered treatments are clinically effective, economically feasible, and embedded within health servicepathways, then access and treatment inequalities for geographically dispersed individuals may well be minimized. Further, the health system will be better positioned in the face of future service disruptions, such as those experienced in 2020-21.
Body Image Distress and Its Associations From an International Sample of Men and Women Across the Adult Life Span: Web-Based Survey Study
BackgroundPrevious research on body image distress mainly relied on samples that were small, generally homogeneous in age or sex, often limited to one geographical region, and were characterized by a lack of comprehensive analysis of multiple psychosocial domains. The research presented in this paper extends the international literature using the results of the web-based Global Health and Wellbeing Survey 2015. The survey included a large sample of both men and women aged ≥16 years from Australia, Canada, New Zealand, the United Kingdom, or the United States.
ObjectiveThe main objectives of this study are to examine body image distress across the adult life span (≥16 years) and sex and assess the association between body image distress and various psychosocial risk and protective factors.
MethodsData were extracted from the Global Health and Wellbeing Survey 2015, a web-based international self-report survey with 10,765 respondents, and compared with previous web-based surveys conducted in 2009 and 2012.
ResultsThe body image distress of young Australians (aged 16-25 years) significantly rose by 33% from 2009 to 2015. In 2015, 75.19% (961/1278) of 16- to 25-year-old adults reported body image distress worldwide, and a decline in body image distress was noted with increasing age. More women reported higher levels of body image distress than men (1953/3338, 58.51% vs 853/2175, 39.22%). Sex, age, current dieting status, perception of weight, psychological distress, alcohol and other substance misuse, and well-being significantly explained 24% of the variance in body image distress in a linear regression (F15,4966=105.8; P<.001).
ConclusionsThis study demonstrates the significant interplay between body image distress and psychosocial factors across age and sex
The efficacy of family treatments for adolescent anorexia nervosa in specialist versus non-specialist settings: protocol for a systematic review and meta-analysis
BackgroundAnorexia nervosa (AN) is often diagnosed in adolescence, and most evidence-based treatments for AN in young people involve the family. Family therapies for AN are intensive, outpatient treatments that utilise the parents as the primary resource in the young person's recovery. Research regarding family treatment for AN is often conducted in specialist settings-with relatively little data reporting the translation of this specialised treatment into real-world, non-specialist settings. This systematic review and meta-analysis aims to determine the efficacy of family treatments for adolescents with AN in specialist settings versus non-specialist settings.MethodsThis systematic review and meta-analysis will be conducted according to the preferred reporting items for systematic reviews and meta-analyses guidelines. Retrospective cohort studies, pilot studies, case series, randomised controlled trials and qualitative investigations that present original data and investigated the efficacy of family treatments for adolescents with AN in either a specialist or non-specialist setting will be included in the review. Data will be extracted by two reviewers and study quality will be assessed. The primary outcome, change in weight, will be used to determine via meta-analysis and, depending on study heterogeneity, subgroup analysis or meta-regression whether there is a statistically significant subgroup difference between specialist and non-specialist treatment settings. The review will also consider changes in eating disorder symptomology and related constructs.DiscussionResults from this review will help determine if there is a difference in the efficacy of family treatments for adolescent AN in specialist versus non-specialist treatment settings, primarily in relation to weight recovery. This, in turn, will inform the translation of evidence-based interventions that are generally studied and implemented within specialist centres into the non-specialist health care system
