Soc Psychiatry Psychiatr Epidemiol 2020 Jul 5. Epub 2020 Jul 5.

Unit for Social and Community Psychiatry (World Health Organisation Collaborating Centre for Mental Health Services Development), Queen Mary University of London, London, UK.

Background: People with severe mental illness often struggle with social relationships, but differences among diagnostic groups are unclear. We assessed and compared objective and subjective social relationship indicators among patients with psychotic, mood and neurotic disorders one year after hospitalisation in five European countries (Belgium, Germany, Italy, Poland and United Kingdom).

Methods: The number of social contacts, including family members and friends during the previous week (Social Network Schedule), and satisfaction with the number and quality of friendships (Manchester Short Assessment of Quality of Life Quality) were assessed by face-to-face interview. Read More

Childhood adversity and psychosis: a systematic review of bio-psycho-social mediators and moderators.

Psychol Med 2020 Jul 6:1-22. Epub 2020 Jul 6.

King's College London, Social, Genetic & Developmental Psychiatry Centre, Institute of Psychiatry, Psychology & Neuroscience, London, UK.

The association between childhood adversity (CA) and psychosis has been extensively investigated in recent years. An increasing body of research has also focused on the mediating or moderating role of biological and psychological mechanisms, as well as other risk factors that might account for the link between CA and psychosis. We conducted a systematic search of the PsychINFO, Embase, Ovid, and Web of Science databases for original articles investigating the role of genetic vulnerabilities, environmental factors, psychological and psychopathological mechanisms in the association between CA and psychosis up to August 2019.

Psychiatric autoimmune conditions in children and adolescents: Is catatonia a severity marker?

Prog Neuropsychopharmacol Biol Psychiatry 2020 Jul 1;104:110028. Epub 2020 Jul 1.

Department of Child and Adolescent Psychiatry, Sorbonne Université, Hôpital Pitié-Salpêtrière, AP-HP, 47-83 Boulevard de l'Hôpital, 75013 Paris, France; GRC 15 PSYDEV. Troubles psychiatriques et développement. Sorbonne Université, Paris, France.

Objectives: Patients with autoimmune encephalitis (AE) are likely to exhibit an acute onset of severe psychiatric features, including psychosis and/or catatonia. Based on the high prevalence of catatonia in AE and our clinical experience, we hypothesized that catatonia might be a marker of severity requiring more aggressive treatment approaches.

Methods: To reach a sufficient number of cases with brain-autoimmune conditions, we pooled two samples (N = 58): the first from the French National Network of Rare Psychiatric diseases and the second from the largest Italian neuro-pediatrics center for encephalopathies. Read More

Contrasting metacognitive profiles and their association with negative symptoms in groups with schizophrenia, early psychosis and depression in a Russian sample.

Psychiatry Res 2020 Jun 7;291:113177. Epub 2020 Jun 7.

Mental-health clinic №1 named after N.A. Alexeev. Zagorodnoye Shosse 2, Moscow Russia.

Research has suggested that negative symptoms in psychotic disorders may be in part fueled by deficits in metacognition or the ability to form integrated ideas about oneself and others. One limitation of this work is that it has largely come from North America and Western Europe. To further the literature, we assessed symptoms using the Positive and Negative Syndrome Scale and Metacognition using the Metacognitive Assessment Scale - Abbreviated in a sample of outpatients with prolonged schizophrenia (n = 41), early episode psychosis (n = 37) and major depression (n = 30) gathered in Moscow, Russia.

Multiple Network Dysconnectivity in Adolescents with Psychotic Experiences: A Longitudinal Population-Based Study.

Schizophr Bull 2020 Jul 2. Epub 2020 Jul 2.

Department of Psychiatry, Smurfit Building, Royal College of Surgeons Ireland at Beaumont Hospital, Dublin, Ireland.

Abnormal functional connectivity (FC, the temporal synchronization of activation across distinct brain regions) of the default mode (DMN), salience (SN), central executive (CEN), and motor (MN) networks is well established in psychosis. However, little is known about FC in individuals, particularly adolescents, reporting subthreshold psychotic experiences (PE) and their trajectory over time. Thus, the aim of this study was to investigate the FC of these networks in adolescents with PE. Read More

The role of dopamine dysregulation and evidence for the transdiagnostic nature of elevated dopamine synthesis in psychosis: a positron emission tomography (PET) study comparing schizophrenia, delusional disorder, and other psychotic disorders.

Neuropsychopharmacology 2020 Jul 1. Epub 2020 Jul 1.

Psychosis Studies Department, Institute of Psychiatry, Psychology & Neuroscience, King's College London, London, UK.

There have been few studies performed to examine the pathophysiological differences between different types of psychosis, such as between delusional disorder (DD) and schizophrenia (SZ). Notably, despite the different clinical characteristics of DD and schizophrenia (SZ), antipsychotics are deemed equally effective pharmaceutical treatments for both conditions. In this context, dopamine dysregulation may be transdiagnostic of the pathophysiology of psychotic disorders such as DD and SZ. Read More

Associations between Self-Disorders and First-Rank Symptoms: An Empirical Study.

Psychopathology 2020 Jul 1:1-8. Epub 2020 Jul 1.

Mental Health Center Copenhagen, Copenhagen, Denmark.

Background: The diagnostic weight of the first-rank symptoms was deemphasized in DSM-5 and a similar change is expected in ICD-11. This change was motivated by a lack of solid, empirical evidence of the diagnostic significance of first-rank symptoms for schizophrenia. Yet, it seems that Schneider's original concept of first-rank symptoms was overly simplified when it was introduced in DSM-III. Read More

Association Between Circulating Lipids and Future Weight Gain in Individuals With an At-Risk Mental State and in First-Episode Psychosis.

Schizophr Bull 2020 Jul 1. Epub 2020 Jul 1.

Turku Bioscience Centre, University of Turku and Åbo Akademi University, Turku, Finland.

Patients with schizophrenia have a lower than average life span, largely due to the increased prevalence of cardiometabolic comorbidities. There is an unmet public health need to identify individuals with psychotic disorders who have a high risk of rapid weight gain and who are at risk of developing metabolic complications. Here, we applied mass spectrometry-based lipidomics in a prospective study comprising 48 healthy controls (CTR), 44 first-episode psychosis (FEP) patients, and 22 individuals at clinical high risk (CHR) for psychosis, from 2 study centers (Turku, Finland and London, UK).

Key Laboratory of Systems Biomedicine (Ministry of Education), Shanghai Centre for Systems Biomedicine, Shanghai Jiao Tong University, Shanghai, China.

Motivation: The mutations of cancers can encode the seeds of their own destruction, in the form of T cell recognizable immunogenic peptides, also known as neoantigens. It is computationally challenging however, to accurately prioritize the potential neoantigen candidates according to their ability of activating the T cell immuno-response, especially when the somatic mutations are abundant. Although a few neoantigen prioritization methods have been proposed to address this issue, advanced machine learning model that is specifically designed to tackle this problem is still lacking.

Inflammation in Mental Disorders: Is the Microbiota the Missing Link?

Neurosci Bull 2020 Jun 27. Epub 2020 Jun 27.

Center for Behavioral Genomics, Department of Psychiatry, Institute for Genomic Medicine, University of California San Diego, La Jolla, CA, 92093, USA.

Research suggests that inflammation is important in the pathophysiology of mental disorders. In addition, a growing body of evidence has led to the concept of the microbiota-gut-brain axis. To understand the potential interactions, we begin by exploring the liaison between the immune system and mental disorders, then we describe the evidence that the microbiota impact the immune response in the developing brain.

INdividual Vocational and Educational Support Trial (INVEST) for young people with borderline personality disorder: study protocol for a randomised controlled trial.

Trials 2020 Jun 26;21(1):583. Epub 2020 Jun 26.

Orygen, 35 Poplar Road, Parkville, Melbourne, VIC, 3052, Australia.

Background: The clinical onset of borderline personality disorder (BPD) usually occurs in young people (aged 12-25 years) and commonly leads to difficulty achieving and maintaining vocational (education and/or employment) engagement. While current psychosocial interventions lead to improvements in psychopathology, they have little effect upon functioning. Individual Placement and Support (IPS) is a client-driven model that assists individuals with severe mental illness to engage with education and/or employment appropriate to their personal goals, and that provides ongoing support to maintain this engagement.

Heterogeneity of emotional experience in schizophrenia: Trait affect profiles predict clinical presentation and functional outcome.

J Abnorm Psychol 2020 Jun 25. Epub 2020 Jun 25.

Department of Psychology.

The current study examined whether subgroups of individuals with schizophrenia could be identified based on their profiles of trait positive and negative emotional experience, and whether those subgroups differed in their symptom presentation and functional outcome. Participants included 192 outpatients diagnosed with schizophrenia or schizoaffective disorder (SZ) and 149 demographically matched healthy controls who completed the trait version of the Positive and Negative Affect Scale, as well as symptom and functional outcome assessments. Cluster analysis determined whether patients could be separated into meaningful subgroups based on their trait emotional experience profiles, and discriminant function analysis determined whether these groups were valid and adequately separated.

Cognitive Remediation Therapy for patients with bipolar disorder: A randomised proof-of-concept trial.

Bipolar Disord 2020 Jun 24. Epub 2020 Jun 24.

Department of Psychological Medicine, Institute of Psychiatry, Psychology & Neuroscience, King's College London, London, UK.

Objectives: Cognitive remediation therapy (CRT) may benefit people with bipolar disorder type I and II for whom cognitive impairment is a major contributor to disability. Extensive research has demonstrated CRT to improve cognition and psychosocial functioning in people with different diagnoses, but randomised trials of evidenced therapy programmes are lacking for bipolar disorders. The Cognitive Remediation in Bipolar (CRiB) study aimed to determine whether an established CRT programme is feasible and acceptable for people with bipolar disorders. Read More

Brain structural correlates of schizotypal signs and subclinical schizophrenia nuclear symptoms in healthy individuals.

Psychol Med 2020 Jun 24:1-10. Epub 2020 Jun 24.

Department of Psychiatry and Psychotherapy, Philipps-Universität Marburg, Rudolf-Bultmann-Str. 8, 35039Marburg, Germany.

Background: Subclinical psychotic-like experiences (PLE), resembling key symptoms of psychotic disorders, are common throughout the general population and possibly associated with psychosis risk. There is evidence that such symptoms are also associated with structural brain changes.

Methods: In 672 healthy individuals, we assessed PLE and associated distress with the symptom-checklist-90R (SCL-90R) scales 'schizotypal signs' (STS) and 'schizophrenia nuclear symptoms' (SNS) and analysed associations with voxel- and surfaced-based brain structural parameters derived from structural magnetic resonance imaging at 3 T with CAT12.

A Mendelian randomization study of the causal association between anxiety phenotypes and schizophrenia.

Am J Med Genet B Neuropsychiatr Genet 2020 Jun 24. Epub 2020 Jun 24.

Centre for Academic Mental Health, Population Health Sciences, Bristol Medical School, University of Bristol, Bristol, UK.

Schizophrenia shows a genetic correlation with both anxiety disorder and neuroticism, a trait strongly associated with anxiety. However, genetic correlations do not discern causality from genetic confounding. We therefore aimed to investigate whether anxiety-related phenotypes lie on the causal pathway to schizophrenia using Mendelian randomization (MR). Read More

Elevated FMR1-mRNA and lowered FMRP - A double-hit mechanism for psychiatric features in men with FMR1 premutations.

Transl Psychiatry 2020 Jun 23;10(1):205. Epub 2020 Jun 23.

Medical Investigation of Neurodevelopmental Disorders (MIND) Institute, University of California Davis Health, Sacramento, CA, USA.

Fragile X syndrome (FXS) is caused by a full mutation of the FMR1 gene (>200 CGG repeats and subsequent methylation), such that there is little or no FMR1 protein (FMRP) produced, leading to intellectual disability (ID). Individuals with the premutation allele (55-200 CGG repeats, generally unmethylated) have elevated FMR1 mRNA levels, a consequence of enhanced transcription, resulting in neuronal toxicity and a spectrum of premutation-associated disorders, including the neurodegenerative disorder fragile X-associated tremor/ataxia syndrome (FXTAS). Here we described 14 patients who had both lowered FMRP and elevated FMR1 mRNA levels, representing dual mechanisms of clinical involvement, which may combine features of both FXS and FXTAS.
