    Eating disorders and substance use disorders frequently co-occur. Twin studies reveal shared genetic risk between eating disorders and substance use, with the strongest associations between symptoms of bulimia nervosa (BN) and problem alcohol use, mainly abuse and dependence (twin-based genetic correlation [rg]=0.23–0.53). Analytic advances facilitate the computation of genetic correlations using summary statistics from existing genome-wide association studies (GWAS). We investigated shared genetic risk between eating disorder and substance use and disorder phenotypes using GWAS data. Four eating disorder phenotypes (anorexia nervosa [AN], AN with binge-eating, AN without binge-eating, and a BN factor score), and eight substance use-related phenotypes (drinks per week, alcohol use disorder [AUD], smoking initiation, current smoking, cigarettes per day, nicotine dependence, cannabis initiation, and cannabis use disorder) from eight studies were included. Total sample sizes per phenotype ranged from ~2,400 to ~537,000 individuals. We used linkage disequilibrium score regression to calculate single nucleotide polymorphism-based genetic correlations between eating disorder and substance use-related phenotypes. Significant positive genetic associations emerged between AUD and AN (rg=0.18; false discovery rate q=0.0006), cannabis initiation and AN (rg=0.23; q<0.0001), and cannabis initiation and AN with binge-eating (rg=0.27; q=0.0016). Conversely, significant negative genetic correlations were observed between three non-diagnostic smoking phenotypes (smoking initiation, smoking cessation, and cigarettes per day) and AN without binge-eating (rgs=−0.19 to −0.23; qs<0.04). The observed patterns of association between different eating disorder and substance use-related phenotypes highlights the potentially complex and substance-specific relationships between these behaviors associated with significant public health burden.

    The paradoxical moderating effects of metacognition in the relationships between self-esteem, depressive symptoms, and quality of life in anorexia and bulimia
    (Eco-Vector, 2023-07-10) Springfield, Cassi R.; Bonfils, Kelsey A.; Chernov, Nikita V.; Moiseeva, Tatyana V.; Sozinova, Marta V.; Dmitryeva, Nadezhda G.; Lysaker, Paul H.; Karpenko, Olga A.; Kostyuk, George P.; Psychiatry, School of Medicine
    Background: Self-esteem and depressive symptoms contribute to a lower quality of life in people suffering from eating disorders. However, limited research has examined whether other factors may affect how these variables influence one another over time. Metacognition is a previously unexplored determinant that may impact the relationships between self-esteem, depressive symptoms, and quality of life in instances of eating disorders. Aim: This study sought to examine metacognitive self-reflectivity and mastery as moderators of the relationships between self-esteem, depressive symptoms, and quality of life and to determine if these relationships are different in people with anorexia compared with people with bulimia. Methods: Participants with anorexia (n=40) and bulimia (n=40) were recruited from outpatient clinics. The participants were assessed on their metacognitive ability and self-reported on measures to assess their depressive symptoms, self-esteem, and quality of life. Results: The results indicate that metacognitive self-reflectivity moderates the relationship between self-esteem, depressive symptoms, and quality of life in people with anorexia such that when self-reflectivity is high, lower self-esteem and higher depressive symptoms are associated with a lower quality of life. These relationships did not appear to be significant when self-reflectivity was low. In contrast, in the anorexia and bulimia groups, metacognitive mastery appeared to moderate the relationships between self-esteem, depressive symptoms, and quality of life such that when mastery was low, lower self-esteem and higher depressive symptoms were associated with a lower quality of life. These relationships did not appear significant when mastery was high. Conclusion: Metacognitive self-reflectivity and mastery seem to play paradoxical moderating roles in the relationships between self-esteem, depressive symptoms, and quality of life in people with anorexia and bulimia. These findings pave the way toward further research and have important clinical implications.

    Wernicke’s encephalopathy in adolescents with anorexia nervosa
    (Elsevier, 2023) Safran, Jeremy T.; Bodaghi, Mahdieh; Sherwin, Nomi K.; Wallace, Jessica R.; Pediatrics, School of Medicine
    Anorexia Nervosa (AN) has always been prevalent in adolescents. During the COVID-19 pandemic, the eating disorder community across the world has noted a sharp increase in adolescent patients with AN and the severity of medical compromise. Rarely seen sequelae have become increasingly more common. This case report describes two previously healthy female adolescents with severe malnutrition due to AN admitted for nutritional stabilization who exhibited paranoid delusions responsive to thiamine and olanzapine. Though neither exhibit the full triad or all the Caine criteria for Wernicke's Encephalopathy (WE), the triad will not present completely in most patients with WE, especially in the pediatric population. Having one symptom of the triad is indicative of WE. Due to the decreased number of clinical criteria for Wernicke's encephalopathy coupled with the lack of typical brain MRI findings found in these patients, we recommend a high index of suspicion for WE and investigation with thiamine. Thiamine supplementation should be standard care in AN with oral supplementation in stable conditions. In the case of refeeding syndromes, preventative parenteral thiamine 100 mg IV qd, and in the case of thiamine deficiency, thiamine 500 mg IV TID.
