Alienation Appraisals Distinguish Adults Diagnosed With DID From PTSD

Studies are beginning to show the importance of appraisals to different types and severities of psychiatric disorders. Yet, little work in this area has assessed whether trauma-related appraisals can differentiate complex trauma-related disorders, such as posttraumatic stress disorder (PTSD) and dissociative identity disorder (DID). The current study evaluated whether any of 6 trauma-related appraisals distinguished adults diagnosed with DID from those diagnosed with PTSD. To accomplish this, we first examined the basic psychometric properties of a Dutch-translated short-form of the Trauma Appraisals Questionnaire (TAQ) in healthy control (n = 57), PTSD (n = 27) and DID (n = 12) samples. The short-form Dutch translation of the TAQ showed good internal reliability and criterion-related validity for all 6 subscales (betrayal, self-blame, fear, alienation, shame, anger). Of the 6 subscales, the alienation appraisal subscale specifically differentiated DID from PTSD, with the former group reporting more alienation. Abuse-related appraisals that emphasize disconnection from self and others may contribute to reported problems of memory and identity common in DID. The current findings suggest that addressing experiences of alienation may be particularly important in treatment for clients diagnosed with DID. (PsycINFO Database Recor

The effect of dialectical behaviour therapy in autism spectrum patients with suicidality and/or self-destructive behaviour (DIASS):study protocol for a multicentre randomised controlled trial

Background: Many persons with autism spectrum disorder (ASD) are treated in long-term specialised care. In this population, suicidal behaviour troubles patients, families, and specialists in the field because it is difficult to treat. At present, there is no documented effective therapy for suicidal behaviour in ASD (Autism Research 7:507-521, 2014; Crisis 35:301-309, 2014). Dialectical Behaviour Therapy (DBT) is an efficacious treatment programme for chronically suicidal and/or self-harm behaviour in patients with Borderline Personality Disorder (J Psychiatry 166:1365-1374, 2014; Linehan MM. Cognitive behavioural therapy of borderline personality disorder. 1993). This study will evaluate the efficacy of DBT in persons with ASD and suicidal/self-destructive behaviour in a multicentre randomised controlled clinical trial. Method: One hundred twenty-eight persons with autism and suicidal and/or self-harming behaviour will be recruited from specialised mental healthcare services and randomised into two conditions: 1) the DBT condition in which the participants have weekly individual cognitive behavioural therapy sessions and a 2.5 h skills training group session twice per week during 6 months, and 2) the treatment as usual condition which consists of weekly individual therapy sessions of 30-45 min with a psychotherapist or social worker. Assessments will take place at baseline, at post-treatment (6 months), and after a follow-up period of 12 months. The mediators will also be assessed at 3 months. The primary outcome is the level of suicidal ideation and behaviour. The secondary outcomes are anxiety and social performance, depression, core symptoms of ASD, quality of life, and cost-utility. Emotion regulation and therapeutic alliance are hypothesised to mediate the effects on the primary outcome. Discussion: The results from this study will provide an evaluation of the efficacy of DBT treatment in persons with ASD on suicidal and self-harming behaviour. The study is conducted in routine mental health services which enhances the generalisability of the study results to clinical practice. Trial registration: ISRCTN96632579. Registered 1 May 2019.

Distinct lipid droplet characteristics and distribution unmask the apparent contradiction of the athlete's paradox

Objective: Intramyocellular lipid (IMCL) storage negatively associates with insulin resistance, albeit not in endurance-trained athletes. We investigated the putative contribution of lipid droplet (LD) morphology and subcellular localization to the so-called athlete's paradox. Methods: We performed quantitative immunofluorescent confocal imaging of muscle biopsy sections from endurance Trained, Lean sedentary, Obese, and Type 2 diabetes (T2DM) participants (n = 8/group). T2DM patients and Trained individuals were matched for IMCL content. Furthermore we performed this analysis in biopsies of T2DM patients before and after a 12-week exercise program (n = 8). Results: We found marked differences in lipid storage morphology between trained subjects and T2DM: the latter group mainly store lipid in larger LDs in the subsarcolemmal (SS) region of type II fibers, whereas Trained store lipid in a higher number of LDs in the intramyofibrillar (IMF) region of type I fibers. In addition, a twelve-week combined endurance and strength exercise program resulted in a LD phenotype shift in T2DM patients partly towards an ‘athlete-like’ phenotype, accompanied by improved insulin sensitivity. Proteins involved in LD turnover were also more abundant in Trained than in T2DM and partly changed in an ‘athlete-like’ fashion in T2DM patients upon exercise training. Conclusions: Our findings provide a physiological explanation for the athlete's paradox and reveal LD morphology and distribution as a major determinant of skeletal muscle insulin sensitivity.
