Background: The literature has shown a significant association between traumatic experiences and eating psychopathology, showing a greater symptomatology in patients with trauma history. Less is known about the associations between trauma and cognitive schemas, and personality traits and the differences between childhood and adulthood trauma experiences. Thus, this paper aims to assess the clinical and psychological characteristics of eating disorder (ED) patients, looking for differences between patients without a history of trauma and patients with trauma experiences, as well as at possible differences between exposure in childhood, adulthood, or repeated events. Another aim of the paper is to evaluate the possible mediation role of cognitive schemas and personality traits in the relationship between early trauma and eating psychopathology.Methods: From January to November 2020, 115 consecutive inpatients admitted for a specific multidisciplinary ED treatment in a dedicated Unit were evaluated for trauma, differentiating between trauma occurring in childhood and adulthood. The subjects were evaluated for early maladaptive schemas (EMS), personality traits, trauma symptomatology, quality of life, and specific psychopathologies linked to EDs. Mediation analyses between childhood and adulthood trauma and eating psychopathology were performed, with EMS and personality traits as mediators.Results: Patients with a history of trauma showed higher physical and psychological symptomatology scores, with a more impaired clinical profile in patients with both childhood and adulthood trauma exposure. The mediation analysis showed a specific mediator role for the “disconnection and rejection (DR)” EMS factor in the relationship between childhood trauma (cT) and eating psychopathology.Conclusion: Trauma experiences are associated with more severe clinical symptomatology in EDs and may need a specific assessment in patients with failed outpatient standard treatments. Specific cognitive schemas linked to DR domain should be evaluated in treatments for ED patients with history of trauma due to the mediation role between trauma and eating psychopathology. The need for outcome studies about treatment approaches for ED patients with history of trauma is discussed.

The research into emotional regulation in eating disorders (EDs) has shown specific impairments and maladaptive coping strategies in patients, and there is an increasing interest in the role of the emotional domain in the treatment outcome. This study aims to evaluate the effect of a specialized inpatient treatment characterized by both an intensive and comprehensive standardized multidisciplinary programme based on cognitive-behavioural therapy and a flexible and personalized component implemented by third-wave interventions. A cohort of 67 female ED patients (anorexia nervosa = 28, bulimia nervosa = 28 and binge eating disorder = 11) underwent an evaluation of emotional regulation difficulties, alexithymia and dissociative symptomatology at admission to a specialized ED ward. The psychological modifications were subsequently re-evaluated upon discharge, after an inpatients treatment of 60 days, examining specific changes in the specific psychopathology. A significant improvement after specialized ED treatment was shown in alexithymia, emotional regulation difficulties and dissociation symptoms, with higher effect sizes in patients with higher alexithymia scores. As regards the specific effect of the psychological improvement, changes into alexithymia scores have shown specific correlations with ED psychopathology (p < 0.010) and with difficulties in emotional regulation (p < 0.010) in patients with higher alexithymia levels at admission. Emotional regulation and dissociation should therefore be evaluated in ED patients and may be improved with specific therapeutic approaches, while alexithymia remains a clinical trait, even with a significant reduction.

Objective There is growing evidence that vitamin D levels have a role not only in bone health and energy metabolism, but also for supporting nervous system and brain functions, including impulsivity. Impulsive behaviours are considered characteristics of great relevance in patients with Eating Disorders (ED) both for the course of the illness and for the treatment. The aim of this study is to examine the relationship between impulsive behaviours and vitamin D in patients with ED. Method 236 patients with a diagnosis of ED, consecutively recruited at an ED ward between 2014 and 2018, were enrolled. Patients were classified as impulsive or non‐impulsive based on the presence of clinically relevant impulsive behaviours. Results Impulsive patients were found to have statistically significant lower levels of vitamin D than non‐impulsive (p = .007). A threshold value of 20.4 ng/ml for discriminating impulsive from non‐impulsive patients was found. Discussion This hypothesis generating study partially confirmed a relationship between vitamin D deficiency and impulsive behaviours in ED spectrum mediated by body weight, even if results were not confirmed after corrected by obesity. No definitive conclusion may be taken on whether the effect is reduced due to the loss of power. Future directions are discussed.

Motor resonance is defined as the internal activation of an observer's motor system, specifically attuned to the perceived movement. In social contexts, however, different patterns of observed and executed muscular activation are frequently required. This is the case, for instance, of seeing a key offered with a precision grip and received by opening the hand. Novel evidence suggests that compatibility effects in motor resonance can be altered by social response preparation. What is not known is how handedness modulates this effect. The present study aimed at determining how a left- and a right-handed actor grasping an object and then asking for a complementary response influences corticospinal activation in left- and right-handers instructed to observe the scene. Transcranial magnetic stimulation (TMS)-induced motor evoked potentials (MEPs) were thus recorded from the dominant hands of left- and right-handers. Interestingly, requests posed by the right-handed actor induced a motor activation in the participants' respective dominant hands, suggesting that left-handers tend to mirror right-handers with their most efficient hand. Whereas requests posed by the left-handed actor activated the anatomically corresponding muscles (i.e., left hand) in all the participants, right-handers included. Motor resonance effects classically reported in the literature were confirmed when observing simple grasping actions performed by the right-handed actor. These findings indicate that handedness influences both congruent motor resonance and complementary motor preparation to observed actions.
