The importance of the family in eating disorders has been the subject of a great deal of speculation ever since anorexia nervosa was first described some 130 years ago. Given the importance of the family in child and adolescent development, it also has great bearing on how young people learn to deal with food. But the research is inconclusive as to the family's precise role in the development of an eating disorder. There is no support in the literature on which to base a comprehensive understanding of the family setting in which a member develops an eating disorder; this also applies to anorexia nervosa cases. When groups of families afflicted with different psychiatric disorders are compared, it seems that families in which bulimia nervosa occurs tend to be more dysfunctional than families afflicted with anorexia nervosa. It also seems that families afflicted with anorexia nervosa function better than families afflicted by other psychiatric disorders. In this article the research on family functioning in relation to anorexia nervosa and bulimia nervosa is reviewed and its relevance discussed.

Objective: Anorexia nervosa (AN) is an eating disorder with the second highest mortality of all mental illnesses and high relapse rate, especially among adult females, yet with no accepted pharmacotherapy. A small number of studies have reported that adult females who struggled with severe and relapsing AN experienced sustained remission of the illness following ketamine infusions. Two other reports showed that 30 mg/kg IP ketamine can reduce vulnerability of adolescent mice to activity-based anorexia (ABA), an animal model of AN.

Anorexia nervosa (AN) is an eating disorder characterized by restriction of energy intake leading to a significantly low body weight, and intense fear of gaining weight. Severe electrolyte changes such as hypokalemia and hypophosphatemia; and alterations in water metabolism such as hyponatremia and edema, can occur in patients with AN. Hypokalemia and chronic volume depletion may lead to acute kidney injury (AKI) and chronic kidney disease (CKD).

Background: Abnormalities in body perception in patients affected by anorexia nervosa have been widely studied, but without explicit reference to their relationship to others and the social processes involved. Yet, there are a several arguments supporting impairments in interpersonal relationships in these patients. Notably, some evidence suggests that self/other distinction (SOD), the ability to distinguish one's own body, actions and mental representations from those of others could be impaired.

Objective: Refeeding oedema, believed to result from the effects of insulin on renal sodium retention and subsequent oedema formation, typically occurs during the first 2 weeks after reintroduction of nutrition in individuals with severe malnutrition and can intensify body image distress in patients with eating disorders (EDs). Phosphate supplements have been found to increase insulin sensitivity, and it is hypothesised that they may also contribute to refeeding oedema in patients with EDs.
Method: In this retrospective cohort study of 633 patients with severe malnutrition due to anorexia nervosa (AN) or avoidant restrictive food intake disorder (ARFID), the impact of phosphate supplementation on the rate of weight gain was investigated.
