Review
Eating disorders are severe psychiatric illnesses with a typical age of onset in adolescence. Brain research in youth and young adults may help us identify specific neurobiology that contributes to onset and maintenance of those disorders. This article provides a state-of-the-art review of our current understanding of the neurobiology of anorexia nervosa and bulimia nervosa. This includes brain structure and function studies to understand food restriction, binge-eating or purging behaviors, cognitive and emotional factors, as well as interoception. Binge-eating disorder and avoidant restrictive food intake disorder are also discussed, but the literature is still very small.

PURPOSE OF REVIEW
To review the recent literature on the epidemiology of anorexia nervosa and bulimia nervosa in terms of incidence, prevalence and mortality.
RECENT FINDINGS
Although the overall incidence rate of anorexia nervosa is considerably stable over the past decades, the incidence among younger persons (aged <15 years) has increased. It is unclear whether this reflects earlier detection or earlier age of onset. Nevertheless, it has implications for future research into risk factors and for prevention programs. For bulimia nervosa, there has been a decline in overall incidence rate over time. The lifetime prevalence rates of anorexia nervosa might be up to 4% among females and 0.3% among males. Regarding bulimia nervosa, up to 3% of females and more than 1% of males suffer from this disorder during their lifetime. While epidemiological studies in the past mainly focused on young females from Western countries, anorexia nervosa and bulimia nervosa are reported worldwide among males and females from all ages. Both eating disorders may carry a five or more times increased mortality risk.
SUMMARY
Anorexia nervosa and bulimia nervosa occur worldwide among females and males of all age groups and are associated with an increased mortality risk.

This article presents current diagnostic conceptualisations of eating disorders, including new disorders such as binge eating disorder (BED) and avoidant/restrictive food intake disorder (ARFID). This is followed by contemporary findings in the epidemiology of eating disorders, their broad sociodemographic distribution and the increases in community prevalence. Advances and the current status of evidence-based treatment and outcomes for the main eating disorders, anorexia nervosa, bulimia nervosa and BED are discussed with focus on first-line psychological therapies. Deficits in knowledge and directions for further research are highlighted, particularly with regard to treatments for BED and ARFID, how to improve treatment engagement and the management of osteopenia.

Treatment of Eating Disorders: a systematic meta-review of meta-analyses and network meta-analyses. NEUROSCI BIOBEHAV REV 21(1) XXX-XXX, 2022.- Treatment efficacy for eating disorders (EDs) is modest and guidelines differ. We summarized findings/quality of (network) meta-analyses (N)MA of randomized controlled trials (RCTs) in EDs. Systematic meta-review ((N)MA of RCTs, ED, active/inactive control), using (anorexia or bulimia or eating disorder) AND (meta-analy*) in PubMed/PsycINFO/Cochrane database up to December 15th, 2020. Standardized mean difference, odds/risk ratio vs control were summarized at end of treatment and follow-up. Interventions involving family (family-based therapy, FBT) outperformed active control in adults/adolescents with anorexia nervosa (AN), and in adolescents with bulimia nervosa (BN). In adults with BN, individual cognitive behavioural therapy (CBT)-ED had the broadest efficacy versus active control; also, antidepressants outperformed active. In mixed age groups with binge-eating disorder (BED), psychotherapy, and lisdexamfetamine outperformed active control. Antidepressants, stimulants outperformed placebo, despite lower acceptability, as did CBT-ED versus waitlist/no treatment. Family-based therapy is effective in AN and BN (adolescents). CBT-ED has the largest efficacy in BN (adults), followed by antidepressants, as well as psychotherapy in BED (mixed). Medications have short-term efficacy in BED (adults).

PURPOSE OF REVIEW
Identifying medications that may be used as therapeutic agents for eating disorders is a longstanding focus of research, with varying degrees of success. The present review consolidates the most recent findings on pharmacological treatment of three eating disorders, including anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED).
RECENT FINDINGS
Recent research suggests that olanzapine demonstrates positive effects on weight gain among outpatients with AN. There are fewer recent advances in psychopharmacological treatment for BN and BED, likely due to the relative success of prior medication trials. Olanzapine is the first medication to safely promote weight gain among individuals with AN. Fluoxetine is FDA-approved for BN treatment, and lisdexamfetamine is FDA-approved for BED treatment. BN and BED also generally respond well to SSRIs prescribed off-label. Research on psychopharmacological treatments for other eating disorders, such as avoidant-restrictive food intake disorder and other specified feeding and eating disorders, are sorely needed.

Review
Systematic review of published studies on the impact of social networks (SN) use on anorexia and bulimia in female adolescents. We selected articles published over the past 10 years, written in English, Spanish or Portu-guese found in The Cochrane Library Plus, PubMed, WOS, PsycINFO, and Scopus databases and with enough methodological quality. Nine studies were included in this review with a sample of 2,069 adolescents; 75.3% were female, mean age was 18 years, and mostly used Facebook and Instagram. Despite some positive aspects, SNs promote beauty standards in terms of thinness, allow comparisons between peers increasing concerns about weight, and create spaces that encourage anorexia and bulimia. Therefore, SN use plays a role in the development of eating disorders. The promotion of extreme thinness in girls makes this population more vulnerable.

Background: eating disorders are a group of conditions in which negative beliefs about food, body shape, and body weight together with behaviors such as restricted food intake, binge eating, excessive exercise, self-induced vomiting, and use of laxatives. They can become serious, affect quality of life, and lead to multiple physical and even psychiatric complications with a fatal outcome. The purpose of this chapter is to describe the characteristics, epidemiology, and trends of eating disorders with updated information based on the most recent publications. Methods: we conducted a systematic literature search in Medline, EMBASE, Cochrane, and Web of Science. The search terms were "anorexia nervosa", "bulimia nervosa", "binge eating disorders" and "epidemiology" both in titles and in abstracts. Results and conclusions: EDs generally occur in adolescents and young adults. The best characterized TCAs are anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (TA). Prevalence studies indicate wide differences by age group and sex, much higher in young women (NA, 0.1-2 %; BN, 0.37-2.98 %; BED, 0.62-4.45 %). The prevalence of EDs is 2.2 % (0.2-13.1 %) in Europe, 3.5 % (0.6-7.8 %) in Asia, and 4.6 % (2.0-13.5 %) in America. Comorbidity is high with psychiatric problems such as depression, anxiety, attention deficit/hyperactivity disorder, obsessive-compulsive disorder, and personality disorders.

Review
Bulimia nervosa, a mental illness 4 times more common than anorexia nervosa, is characterized by binge-eating followed by compensatory purging behaviors, which include self-induced vomiting, diuretic abuse, laxative abuse, and misuse of insulin. Patients with bulimia nervosa are at risk of developing medical complications that affect all body systems, especially the renal and electrolyte systems. Behavior cessation can reverse some, but not all, medical complications.

Review
A review of the literature on emotion regulation in binge eating disorder (BED) published both in English and Polish between 1990 and 2020. BED might be considered as an impulsive and compulsive disorder associated with altered reward sensitivity and food-related attentional bias. The growing body of research indicated that there were corticostriatal circuitry alterations in BED, comparable to those observed in substance abuse, including altered function of orbitofrontal, prefrontal and insular cortices with the striatum included. Negative emotions and deficits in their regulation play a significant role in BED. Processing of anger, anxiety and sadness appear to be particularly important in this disorder. Research results identified an increase in negative emotions preceding episodes of binge eating. However, there is still inconsistency when it comes to whether these episodes alleviate negative affect. Individuals with BED more often use non-adaptive emotion regulation strategies, such as rumination and suppression of negative sensations. Whereas adaptive ones, for instance, cognitive reappraisal, are used less often. Clinical implications, besides pharmacology, highlight the high effectiveness of enhanced cognitive behavioral therapy (CBT-E), dialectic-behavioral therapy (DBT) and psychodynamic therapy in the treatment of emotional dysregulation in BED. Further studies, including ecological momentary assessment (EMA), should focus on emotional changes related to the binge cycle and the identification of reinforcing factors of BED.
