“…These responses can contribute to disruptions in the absorption and utilisation of nutrients. The psychological distress can also lead to neglect of self-care, including adequate nutrition, further compounding the malnutrition-associated skin manifestations [ 19 ].…”

The intricate interplay between eating disorders, malnutrition, and their cutaneous manifestations is the focal point of this comprehensive review. The review delves into the clinical significance of recognising and understanding these visible signs in the context of eating disorders. It highlights the vital role of nutrition in maintaining healthy skin and addresses the challenges associated with relying solely on cutaneous signs for diagnosis. Emphasising a multidisciplinary approach involving dermatologists, psychiatrists, and nutritionists, the review underscores the holistic nature of the treatment. Addressing psychological aspects alongside nutritional rehabilitation is underscored with a forward-looking perspective on future research avenues. This review is valuable for healthcare professionals by synthesising existing knowledge and identifying research gaps. It aims to improve the diagnosis, treatment, and preventative strategies for individuals dealing with the complex challenges of eating disorders and malnutrition.

“…However, approximately half of the individuals diagnosed with AN have been observed to experience a transition from AN-R to disorders characterized by binge eating and purging behaviors, namely AN-BP and BN [ 22 ]. Moreover, several studies reported that the inability for mentalization and empathy is also shown in both AN and BN [ 23 , 24 ]. In their review, Zanella et al [ 24 ] stated that interpersonal and emotion regulation theories contribute to problematic eating.…”

Background Feeding and eating disorders are severe mental disorders that gravely affect patients’ lives. In particular, patients with anorexia nervosa (AN) or bulimia nervosa (BN) appear to have poor social cognition. Many studies have shown the relationship between poor social cognition and brain responses in AN. However, few studies have examined the relationship between social cognition and BN. Therefore, we examined which brain regions impact the ability for social cognition in patients with BN. Methods We used task-based functional magnetic resonance imaging (fMRI) to examine brain responses during a social cognition task and the Reading Mind in the Eyes Test (RMET). During the fMRI, 22 women with BN and 22 healthy women (HW) took the RMET. Participants also completed the eating disorder clinical measures Bulimic Investigatory Test, Edinburgh (BITE) and Eating Disorders Examination Questionnaire (EDE-Q), the Patient Health Questionnaire (PHQ-9) measure of depression; and the Generalized Anxiety Disorder (GAD-7) measure of anxiety. Results No difference was observed in the RMET scores between women with BN and HW. Both groups showed activation in brain regions specific to social cognition. During the task, no differences were shown between the groups in the BOLD signal (p < 0.05, familywise error corrected for multiple comparisons). However, there was a tendency of more robust activation in the right angular gyrus, ventral diencephalon, thalamus proper, temporal pole, and middle temporal gyrus in BN (p < 0.001, uncorrected for multiple comparisons). Moreover, HW showed a positive correlation between RMET scores and the activation of two regions: medial prefrontal cortex (mPFC) and anterior cingulate cortex (ACC); however, no significant correlation was observed in women with BN. Conclusions While activation in the mPFC and ACC positively correlated to the RMET scores in HW, no correlation was observed in BN patients. Therefore, women with BN might display modulated neural processing when thinking of others’ mental states. Further examination is needed to investigate neural processing in BN patients to better understand their social cognition abilities. Trial registration UMIN, UMIN000010220.

“…The multidimensional nature of ED, with many risk and protective mechanisms, encourages researchers to probe for any possible forms of interaction between these factors. By using various methods of multivariate analysis, we are able to assess the moderation and mediation effects of such interactions that offer different etiological and maintenance models of ED [41,43,73-76] .…”

BACKGROUND: Eating disorders (ED) are severe, chronic and complex in nature mental illness difficult to treat. One of the areas of ED prevention is screening among adolescents to prevent the development of clinical forms of ED in risk groups. AIMS: 1) to investigate the prevalence of ED risk among adolescent girls and compare subgroups at high and low risk of ED; 2) to investigate using a multidimensional approach those variables that can interact with temperament and character traits to predict ED symptomatology. METHODS: The cross-sectional observational self-report study of a community sample of adolescent girls 12-17 years old (n=298; M=14.771.13) was carried out in Ryazan city. The Russian versions of Eating Attitudes Test and Cloningers Temperament and Character Inventory-Revised were used. In addition, an original questionnaire (Risk Factors of Eating Disorders) was developed. Regression models (to test for significant moderations) and path analysis (to test significant mediations) were used. RESULTS: Girls with ED risk are characterized by high weight concerns and body dissatisfaction, low self-directedness, higher novelty seeking and tendency to higher harm avoidance, high alexithymia, self-distrust, negative emotionality and family relationships dissatisfaction, low self-esteem and tendencies to higher perfectionism and risk behavior. Significant moderations were obtained between the following ED risk factors: 1) self-distrust/risk behavior and BMI; 2) alexithymia/negative emotionality/self-esteem and cooperativeness; 3) negative emotionality/risk behavior and self-transcendence. Family relationship dissatisfaction mediates association between self-directedness/cooperativeness/self-transcendence and disordered eating. CONCLUSION: There are various mutual influences between the numerous ED risk and prevention factors, which determine the paths between the predictor and the outcome.
