Abstract
BACKGROUND Abnormalities in cerebral blood flow (CBF) are common in bipolar disorder (BD). Despite known differences in CBF between healthy adolescent males and females, sex differences in CBF among adolescents with BD have never been studied. OBJECTIVE To examine sex differences in CBF among adolescents with BD versus healthy controls (HC). METHODS CBF images were acquired using arterial spin labeling (ASL) perfusion magnetic resonance imaging (MRI) in 123 adolescents (72 BD: 30M, 42F; 51 HC: 22M, 29F) matched for age (13-20 years). Whole brain voxel-wise analysis was performed in a general linear model with sex and diagnosis as fixed factors, sex-diagnosis interaction effect, and age as a covariate. We tested for main effects of sex, diagnosis, and their interaction. Results were thresholded at cluster forming p = 0.0125, with posthoc Bonferroni correction (p = 0.05/4 groups). RESULTS A main effect of diagnosis (BD > HC) was observed in the superior longitudinal fasciculus (SLF), underlying the left precentral gyrus (F =10.24 (3), p < 0.0001). A main effect of sex (F > M) on CBF was detected in the precuneus/posterior cingulate cortex (PCC), left frontal and occipital poles, left thalamus, left SLF, and right inferior longitudinal fasciculus (ILF). No regions demonstrated a significant sex-by-diagnosis interaction. Exploratory pairwise testing in regions with a main effect of sex revealed greater CBF in females with BD versus HC in the precuneus/PCC (F = 7.1 (3), p < 0.01). CONCLUSION Greater CBF in female adolescents with BD versus HC in the precuneus/PCC may reflect the role of this region in the neurobiological sex differences of adolescent-onset BD. Larger studies targeting underlying mechanisms, such as mitochondrial dysfunction or oxidative stress, are warranted.

Abstract
BACKGROUND The coronavirus disease 2019 pandemic represents an unprecedented traumatic stressor to mental health. Psychological distress is considered a reliable proxy for psychopathology and can be negatively influenced by childhood trauma through sensitization effects. Emotion dysregulation has been proposed as a potential mediator of this mechanism. We aimed to test this hypothesis in a national Italian sample assessed in the early phase of the coronavirus disease 2019 outbreak. METHODS We investigated the relationship between psychological distress and childhood trauma in 500 healthy participants assessed through a survey-based study, after the coronavirus disease 2019 pandemic lockdown in Italy. Levels of psychological distress and history of childhood trauma were obtained using the Kessler-10 (K10) and the Childhood Trauma Questionnaire, respectively. We used bootstrapped mediation analysis to test the mediator role of emotional dysregulation, measured through the Difficulties in Emotion Regulation Scale, on the effect of childhood trauma on psychological distress. RESULTS In total, 190 (38%) reported psychological distress related to the coronavirus disease 2019 outbreak. Individuals with psychological distress experienced more childhood trauma, specifically emotional abuse (F = 23.51, df = 1, p < 0.001) and neglect (F = 10.98, df = 1, p = 0.001). After modelling the effect of emotional dysregulation, the impact of childhood trauma on coronavirus disease 2019-related psychological distress resulted in indirect effects and mediated by deficits in emotion regulation mechanisms (bootstrapped lower level of confidence interval = 0.345, upper level of confidence interval = 0.598). CONCLUSION Childhood trauma is associated with increased vulnerability to the stressful effect of the coronavirus disease 2019 outbreak. Our data suggest that emotional dysregulation may represent a dimension mediating the impact of childhood trauma on coronavirus disease 2019-related psychological distress and may be considered as specific target for interventions aiming at empowering resilience.

Decentering as a core component in the psychological treatment and prevention of youth anxiety and depression: a narrative review and insight report. Transl Psychiatry 2021; 11:288. [PMID: 33990541 PMCID: PMC8121888 DOI: 10.1038/s41398-021-01397-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 04/20/2021] [Accepted: 04/21/2021] [Indexed: 12/12/2022] Open
Abstract
Decentering is a ubiquitous therapeutic concept featuring in multiple schools of psychological intervention and science. It describes an ability to notice to day-to-day psychological stressors (negative thoughts, feelings, and memories) from an objective self-perspective and without perseverating on the themes they represent. Thus, decentering dampens the impact and distress associated with psychological stressors that can otherwise increase mental ill health in vulnerable individuals. Importantly, the strengthening of decentering-related abilities has been flagged as a core component of psychological interventions that treat and prevent anxiety and depression. We provide an in-depth review evidence of the salutary effects of decentering with a special focus on youth mental health. This is because adolescence is a critical window for the development of psychopathology but is often under-represented in this research line. A narrative synthesis is presented that integrates and summarizes findings on a range of decentering-related abilities. Section 1 reviews extant conceptualizations of decentering and data-driven approaches to characterize its characteristic. A novel definition is then offered to guide future empirical research. Section 2 overviews laboratory-based research into the development of decentering as well as its relationship with anxiety and depression. Section 3 examines the role decentering-related skills play in psychological interventions for anxiety and depression. Critically, we review evidence that treatment-related increases in decentering predict latter reductions in anxiety and depression severity. Each section highlights important areas for future research. The report concludes by addressing the vital questions of whether, how, why and when decentering alleviates youth anxiety and depression.

Looking for the Good Timing: Predictors of Length of Stay and Therapeutic Outcomes in Adolescent Inpatients with Severe or Treatment-Refractory Mood Disorders. J Child Adolesc Psychopharmacol 2021; 31:268-278.

Abstract
Objectives: While hospitalization is an essential aspect of the therapeutic strategy for adolescents with severe or treatment-refractory mood disorders, little is known about the outcome predictors during inpatient treatment. Methods: A retrospective chart review was conducted in a university tertiary referral hospital to determine the factors associated with the length of stay, symptom improvement (based on the Clinical Global Impression-Improvement [CGI-I] scale), and the change in the overall level of functioning during the stay (based on the Children-Global Assessment Scale [CGAS]). Over 2 years, 106 adolescents were diagnosed with mood disorders (mean age = 15.0 ± 0.16; 43% girls), with a particular high rate of associated adverse psychosocial factors, and an average length of stay longer than most psychiatric hospital settings (mean = 100.7 ± 9.57 days). Results: Multivariate analysis concluded that longer duration of current episode and worse functioning at admission (CGAS score) were independent predictors for length of stay. Greater functional improvement (CGAS score change from admission to discharge) was best predicted by the diagnosis of bipolar disorder, lower functioning, and greater illness severity on admission. Symptom improvement (CGI-I) did not have any independent predictors. Conclusion: This finding supports the value of measuring symptoms duration in predicting the hospitalization outcomes of adolescents with severe or treatment-refractory mood disorders, in view of addressing maintenance factors at an early stage. Bipolar symptoms should be sought not only at admission but also regularly during the stay.
