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).

Meta-Analysis Review
IMPORTANCE
Cannabis and cannabinoid drugs are widely used to treat disease or alleviate symptoms, but their efficacy for specific indications is not clear.
OBJECTIVE
To conduct a systematic review of the benefits and adverse events (AEs) of cannabinoids.
DATA SOURCES
Twenty-eight databases from inception to April 2015.
STUDY SELECTION
Randomized clinical trials of cannabinoids for the following indications: nausea and vomiting due to chemotherapy, appetite stimulation in HIV/AIDS, chronic pain, spasticity due to multiple sclerosis or paraplegia, depression, anxiety disorder, sleep disorder, psychosis, glaucoma, or Tourette syndrome.
DATA EXTRACTION AND SYNTHESIS
Study quality was assessed using the Cochrane risk of bias tool. All review stages were conducted independently by 2 reviewers. Where possible, data were pooled using random-effects meta-analysis.
MAIN OUTCOMES AND MEASURES
Patient-relevant/disease-specific outcomes, activities of daily living, quality of life, global impression of change, and AEs.
RESULTS
A total of 79 trials (6462 participants) were included; 4 were judged at low risk of bias. Most trials showed improvement in symptoms associated with cannabinoids but these associations did not reach statistical significance in all trials. Compared with placebo, cannabinoids were associated with a greater average number of patients showing a complete nausea and vomiting response (47% vs 20%; odds ratio [OR], 3.82 [95% CI, 1.55-9.42]; 3 trials), reduction in pain (37% vs 31%; OR, 1.41 [95% CI, 0.99-2.00]; 8 trials), a greater average reduction in numerical rating scale pain assessment (on a 0-10-point scale; weighted mean difference [WMD], -0.46 [95% CI, -0.80 to -0.11]; 6 trials), and average reduction in the Ashworth spasticity scale (WMD, -0.36 [95% CI, -0.69 to -0.05]; 7 trials). There was an increased risk of short-term AEs with cannabinoids, including serious AEs. Common AEs included dizziness, dry mouth, nausea, fatigue, somnolence, euphoria, vomiting, disorientation, drowsiness, confusion, loss of balance, and hallucination.
CONCLUSIONS AND RELEVANCE
There was moderate-quality evidence to support the use of cannabinoids for the treatment of chronic pain and spasticity. There was low-quality evidence suggesting that cannabinoids were associated with improvements in nausea and vomiting due to chemotherapy, weight gain in HIV infection, sleep disorders, and Tourette syndrome. Cannabinoids were associated with an increased risk of short-term AEs.

Meta-Analysis Review
BACKGROUND AND AIMS
The concept of "Food Addiction" has been based on criteria of Substance Use Disorder. Several studies suggested a relationship between food addiction and eating disorders, but little is known about its extent or role. We aim at exploring if food addiction is coincident with a specific eating disorder (binge eating disorder appears the closest) or it is a separate diagnostic entity that afflicts in comorbidity with eating disorders or other conditions like obesity or even in the general population.
METHODS
This systematic review and meta-analysis analyzed observational studies with a comparative estimation on rates of subjects affected by binge eating disorder and food addiction.
RESULTS
Binge eating disorder shows higher comorbidity with food addiction compared to other eating disorders (OR = 1.33, 95% CI, 0.64-2.76; c = 4.42; p = 0.44;I = 0%), or each eating disorder [anorexia nervosa purging type (OR = 1.93, 95% CI, 0.20-18.92; p = 0.57) and restrictive type (OR = 8.75, 95% CI, 1.08-70.70; p = 0.04)], obese patients (OR = 5.72, 95% CI, 3.25-10.09; p = < 0.0001) and individuals from the general population (OR = 55.41, 95% CI, 8.16-376.10; c = 18.50; p < 0.0001; I = 0%)but has decreased prevalence when compared to bulimia nervosa (OR = 0.85, 95% CI, 0.33-2.22; c = 0.35; p = 0.74; I = 0%).
DISCUSSION AND CONCLUSIONS
Our data show that the prevalence of food addiction in binge eating disorder is higher than in other eating disorders except in bulimia nervosa. Moreover, it is a separate diagnostic reality and can be detected in people without mental illness and in the general population. Food addiction might have a prognostic value, since in comorbidity, and should be addressed to boost treatment efficacy and patient's recovery.

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.

Review
OBJECTIVE
A description of atypical anorexia nervosa (atypical AN) was provided in DSM-5 in 2013 and a sizable literature has since developed describing the clinical features of individuals with atypical AN and comparing them to those of individuals with anorexia nervosa (AN) and those of healthy individuals. The purpose of this study was to conduct a systematic review of this literature.
METHOD
A systematic review following PRISMA guidelines was conducted of studies published since 2013 that compared the clinical characteristics of individuals with atypical AN to those of individuals with AN and/or healthy controls. Meta-analyses were conducted when similar measures were reported in three or more studies.
RESULTS
Twenty-four publications met criteria for inclusion. Their results indicated that the level of eating disorder-specific psychopathology is significantly higher among individuals with atypical AN than among controls and as high or higher as among individuals with AN while levels of non-eating disorder psychopathology are similar. Individuals with atypical AN experience many of the physiological complications associated with AN, but some complications appear less frequent.
DISCUSSION
The psychological symptoms and physiological complications of individuals with atypical AN are generally similar to those of individuals with AN, although there may be differences in the frequency of some physical complications. Little information is available on the course, outcome, and treatment response of individuals with atypical AN. In addition, full diagnostic criteria for atypical AN have not been developed, and the nosological relationship of atypical AN to established eating disorders such as bulimia nervosa is unclear.
PUBLIC SIGNIFICANCE
Atypical anorexia nervosa as described in the DSM-5 identifies individuals with many of the psychological characteristics of typical anorexia nervosa who, despite significant weight loss, are not underweight. The current systematic review found that the psychological symptoms and physiological characteristics of individuals with atypical AN are generally similar to those of individuals with AN, although there may be differences in the frequency of some physical complications.

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
Anorexia nervosa is a potentially severe, chronic, and relapsing mental disorder that is more common in women and girls during the reproductive years (usually defined as those aged 12-51 years). It is associated with suicide and mortality linked with the physical consequences of starvation. Although anorexia nervosa is a disorder of low prevalence, and even lower prevalence in pregnancy, it is associated with substantial risks for the mother and infant when under-recognised and undermanaged. Despite the complexity and risk of managing anorexia nervosa in pregnancy, few studies are available to guide care. We conducted a systematic review, identifying only eight studies that addressed the management of anorexia nervosa in pregnancy. These studies were case studies or case reports examining narrow aspects of management. Subsequently, we conducted a state-of-the-art review across research in relevant disciplines and areas of expertise for managing anorexia nervosa in pregnancy and synthesised the findings into recommendations and principles for multidisciplinary management of anorexia nervosa in pregnancy. These recommendations included a focus on the specialist mental health, obstetric, medical, and nutritional care required to ensure optimal outcomes for women and their infants. Despite the complexity and risks, a gap exists in the comprehensive guidelines and recommendations for managing anorexia nervosa in pregnancy. This Review provides multidisciplinary recommendations for clinical care in this area. Managing anorexia nervosa in pregnancy is an area of clinical care that requires a multidisciplinary approach and includes those experienced in managing high-risk pregnancies.

Review
BACKGROUND
Recent research has shown a growing interest in exploring the relationship between anorexia nervosa (AN) and autism spectrum disorder (ASD). Both conditions seem to share areas of cognitive, social and behavioural impairment, leading to relevant implications on treatment, especially when they are in comorbidity. This literature review aims to synthesise the latest studies on this topic to investigate the co-occurrence of AN and ASD, suggest future research directions and consider implications for treatment.
METHOD
Records were systematically (PRISMA guidelines) identified through PubMed, EBSCOhost, Scopus and Web of Science searching.
RESULTS
Thirteen studies met the eligibility criteria and were therefore included in the review. Results seem to confirm an overrepresentation of ASD symptoms in AN. Only few studies investigated the AN-ASD comorbidity in young people and report slightly lower rates than those conducted with adults.
CONCLUSIONS
Analysed studies suggest that while the comorbidity seems to exacerbate the severity of the condition, autistic traits appear to be rather stable over time and not related to body weight. Thus, future longitudinal studies and gender- specific assessment tools can help clarify the relationship between the two disorders, examine the onset of ASD symptoms and develop structured guidelines for treatment.

Review
OBJECTIVE
A growing body of evidence suggests that individuals with eating disorders (EDs) have experienced deteriorating symptoms, increased isolation, and an increase in hospital admissions as a result of the COVID-19 pandemic. Despite this, no systematic reviews have been conducted examining the COVID-19 and ED peer-reviewed literature. Therefore, this systematic review aimed to synthesize the impact of the COVID-19 pandemic on individuals with EDs.
METHOD
Database searches of the peer-reviewed literature were completed in the subsequent databases: CINAHL, Embase, MEDLINE, and PsycINFO (from November 2019 to October 20, 2021). All research reporting on the relationship between the COVID-19 pandemic on individuals with EDs were included.
RESULTS
Fifty-three studies met the inclusion criteria, including 36,485 individuals with EDs. The pooled hospital admissions across the studies demonstrated on average a 48% (pre = 591, post = 876, n = 10 studies) increase in admissions during the pandemic compared to previous pre-pandemic timepoints. In this review, 36% of studies (n = 19) documented increases in eating disorder symptoms during the pandemic, this increase in eating disorder symptoms were documented in AN, BED, BN, and OFSED patients. Studies also demonstrated increases in anxiety (n = 9) and depression (n = 8), however patterns of change appeared to be diagnostic and timing specific (e.g., lockdowns).
DISCUSSION
We found a large increase in the number of hospitalizations and an increase in ED symptoms, anxiety, depression, and changes to BMI in ED patients during the pandemic. However, these changes appeared to be diagnostic and timing specific. Many qualitative studies described deterioration in ED symptomatology due to decreased access to care and treatment, changes to routine and loss of structure, negative influence of the media, and social isolation. Future studies are needed to focus on pediatric populations, new ED diagnoses, and severity of illness at presentation.
PUBLIC SIGNIFICANCE
The scientific literature suggests that individuals with eating disorders have experienced deteriorating symptoms, increased isolation, and an increase in hospital admissions as a result of the COVID-19 pandemic. This study synthesized 53 articles and explored the impact of the COVID-19 pandemic on patients with eating disorders. We found increases in eating disorder symptoms during the pandemic; this increase in eating disorder symptoms was documented in patients with common eating disorders including anorexia nervosa, binge-eating disorder, bulimia nervosa, and other specified feeding and eating disorders. This review also demonstrated changes in body mass index (an index used to classify underweight, overweight, and obesity in adults) and increases in anxiety and depression during the pandemic compared to previous timepoints; patterns of change appeared to be related to timing of lockdowns. This review provides important information on the impact of COVID-19 on the physical and mental health of individuals with eating disorders.

Meta-Analysis Review
OBJECTIVE
Anorexia nervosa (AN) is a severe psychiatric disorder characterized by starvation and malnutrition, a high incidence of coexisting psychiatric conditions, and treatment resistance. The effect of pharmacotherapy has been controversial.
METHOD
A systematic review was conducted for evidence of an effect of olanzapine versus placebo in adults or its effect as adjuvant treatment of AN in adolescents.
RESULTS
A total of seven articles (304 patients with AN) were identified. There were four double-blind, randomized studies examining the effect of olanzapine in the treatment of AN. The mean difference in body mass index (BMI) at the end of treatment between olanzapine and placebo was 0.67 kg/m (95% confidence interval (CI) 0.15-1.18 kg/m ; p = 0.01; I = 0%, p for heterogeneity < 0.79). The olanzapine groups showed a significant increase in BMI of 0.68 kg/m (95% CI 0.22-1.13 kg/m ; p < 0.001; I = 0%, p for heterogeneity = 0.74) compared to the placebo groups. Only two studies examined the effect of olanzapine as adjuvant treatment in adolescents and showed an increase in BMI of 0.66 kg/m (95% CI -0.36 to 1.67 kg/m ; p = 0.21; I = 11%, p for heterogeneity = 0.32).
DISCUSSION
Olanzapine showed efficacy in the treatment of AN with an increased BMI at the end of treatment in adults. The effect of olanzapine as adjuvant treatment in adolescents remains unclear.
