Stresses like low nutrients, systemic inflammation, cancer or infections provoke a catabolic state characterized by enhanced muscle proteolysis and amino acid release to sustain liver gluconeogenesis and tissue protein synthesis. These conditions activate the family of Forkhead Box (Fox) O transcription factors. Here we report that muscle-specific deletion of FoxO members protects from muscle loss as a result of the role of FoxOs in the induction of autophagy–lysosome and ubiquitin–proteasome systems. Notably, in the setting of low nutrient signalling, we demonstrate that FoxOs are required for Akt activity but not for mTOR signalling. FoxOs control several stress–response pathways such as the unfolded protein response, ROS detoxification, DNA repair and translation. Finally, we identify FoxO-dependent ubiquitin ligases including MUSA1 and a previously uncharacterised ligase termed SMART (Specific of Muscle Atrophy and Regulated by Transcription). Our findings underscore the central function of FoxOs in coordinating a variety of stress-response genes during catabolic conditions.

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; c2 = 4.42; p = 0.44;I2 = 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; c2 = 18.50; p < 0.0001; I2 = 0%)but has decreased prevalence when compared to bulimia nervosa (OR = 0.85, 95% CI, 0.33–2.22; c2 = 0.35; p = 0.74; I2 = 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. Level of evidence I: Evidence obtained systematic reviews and meta-analyses.

BackgroundChildhood maltreatment is the most important risk factor for the onset of psychiatric disorders. Revictimization is really frequent as well as substance or alcohol abuse, often linked to self-treatment. Accordingly, our pilot study aims to analyze possible implication of childhood maltreatment on resilience and burnout.MethodsPatients admitted to outpatients psychiatric department in a six month period (1st January 2015–30th June 2015) complaining low to moderate anxiety or depression have been administered childhood trauma questionnaire (CTQ) and Maslach burnout inventory.ResultsCTQ results in 71 (87%) Emotional Neglect (EN), 2 (2.4%) Sexual Abuse (SA) and 2 (2.4%) Physical Abuse (PA). Twenty-one showed high emotional exhaustion, 21 high depersonalization, 9 moderate personal accomplishment while 1 showed low personal accomplishment. None of the patients who suffered child sexual abuse shows depersonalization or personal accomplishment difficulties linked to burnout. Patients negative to CTQ show respectively moderate emotional exhaustion (M = 20 ± 20.15), moderate depersonalization (11 ± 9.42) and high personal accomplishment (17 ± 12.38). Patients who suffered emotional neglect show the poorest profile at Maslach, particularly regarding emotional exhaustion. ANOVA reaches statistical significance among the 3 groups of detected abuse (EN, SA, PA) in personal accomplishment (P = 0.013) confirmed at POST HOC between EN and SA (P = 0.0004).ConclusionThe results obtained in this pilot study highlight two important considerations. First, it seems urgent to stress the huge prevalence of emotional neglect among those referred to psychiatric outpatient department due to moderate anxiety or depression complain. Moreover, emotional neglect appears to be the most compromised factor of burnout, especially if compared to sexual abuse.

<b><i>Background:</i></b> Cannabis use during pregnancy may adversely affect the health of pregnant women and their fetus. Several recent surveys led in the US general population in the last decade showed an increase in cannabis use during pregnancy from 1.95 to 7%, with a 0.5% for medical-only purposes. <b><i>Objectives:</i></b> Our aim was to investigate if an increased incidence might be due to a greater public acceptability after introduction of cannabis medical use or due to psychiatric implications and unmet needs. <b><i>Method:</i></b> 500 pregnant women (302 psychiatric patients and 198 healthy controls) were tested with the Edimburgh Post-Natal Depression Scale, Beck Anxiety and Depression Inventory, and Structured Clinical Interview for the DSM-IV Axis II while substance use disorder was documented with the fulfillment of the DSM-5 criteria. <b><i>Results:</i></b> Five percent of the whole sample had a documented addiction to cannabis during pregnancy (all among psychiatric patients and none in the general population). All psychiatric patients with cannabis use disorder were affected by borderline personality disorder, except for 1 patient with cannabis and cocaine use disorders who suffered from adjustment disorder with anxiety. <b><i>Conclusions:</i></b> Addiction to cannabis during pregnancy has an increased rate confirming surveys on the general US population but seem entirely linked to psychiatric issues, especially borderline personality disorder. Personality disorders may have been underestimated in surveys in the general population until now because these are usually not assessed.
