Although relationships between negative affect, emotion dysregulation, and binge eating have been well-established, the mechanisms and individual risk factors that account for this relationship have yet to be elucidated. In addition to emotion dysregulation, altered reward functioning and negative affect eating expectancies (i.e., the expectancy that eating will relieve negative affect) are factors that have been previously linked to binge eating, though theoretical frameworks have not provided an integrated conceptualization of relationships between these domains. Therefore, the present study examined an integrative moderated mediation model among a sample of 101 adults with self-reported eating disorder (ED) symptoms who completed a battery of online questionnaires. Results supported the hypothesized model, which demonstrated that eating expectancies mediated the relationship between emotion dysregulation and binge eating frequency, and there was a positive association between emotion dysregulation and eating expectancies among individuals high in anticipatory reward. These findings provide preliminary support for an integrated approach to understanding transdiagnostic and ED-specific risk factors that potentiate binge eating.

Feeding and eating disorders (FEDs) are a heterogeneous grouping of disorders at the mind-body interface, with typical onset from childhood into emerging adulthood. They occur along a spectrum of disordered eating and compensatory weight management behaviors, and from low to high body weight. Psychiatric comorbidities are the norm.

Slimmer's paralysis is a peripheral mononeuropathy of the common peroneal (fibular) nerve (CPN/CFN), typically associated with rapid weight loss resulting in loss of subcutaneous fat pad and subsequent neural compression at the fibular head. Here, we describe a young man with a 1-year history of right-sided foot drop, which developed following a rapid intentional weight loss of 11 kg over a period of 15 days. This weight loss was preceded by rapid weight gain over 2 days owing to binge eating.

This study examined laxative and substance use in adults with an eating disorder, and the association with depression, compulsions, and obsessions. A retrospective chart review of 182 women who had a formal diagnosis of an eating disorder and were receiving specialized outpatient treatment was conducted. The chart review included questionnaires completed at intake assessment, including a demographic survey with questions asking about laxative use, substance use, and the types of substances used.

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors-serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol-and their roles in the pathophysiology of PCOS and associated psychiatric symptoms.
