  • Mapping genomic loci implicates genes and synaptic biology in schizophrenia

    Open Access•Vassily Trubetskoy, Antonio F Pardiñas et al.•ARTICLE•Nature•2022

  • Preventive Medication Patterns in Bipolar Disorder and Their Relationship With Comorbid Substance Use Disorders in a Cross-National Observational Study

    Open Access•Romain Icick, Ingrid Melle et al.•ARTICLE•Frontiers in Psychiatry•2022

    SUD comorbidity in BD was overall not associated with different pharmacological treatment in our sample, and not related to the level of compliance to guidelines. We found country-specific associations between comorbid SUDs and specific medications that warrant further studies

  • Lifetime Cannabis Use Is Not Associated With Negative Beliefs About Medication in Patients With First Treatment Psychosis

    Open Access•Priyanthi B Gjerde, Synne W Steen et al.•ARTICLE•Frontiers in Psychiatry•2022

    Use of cannabis is not linked to negative perceptions about antipsychotic medicines in patients with FTP. Other reasons for poor compliance to antipsychotic drug treatment in cannabis users need to be further investigated

  • Adiponectin Is Related to Cardiovascular Risk in Severe Mental Illness Independent of Antipsychotic Treatment

    Open Access•Elina J Reponen, Martin Tesli et al.•ARTICLE•Frontiers in Psychiatry•2021

    Background: Schizophrenia (SCZ) and bipolar disorder (BD) are severe mental illnesses (SMI) associated with elevated cardiovascular disease (CVD) risk, including obesity. Leptin and adiponectin are secreted by adipose tissue, with pro- and anti-inflammatory properties, respectively. The second generation antipsychotics (AP) olanzapine, clozapine, and quetiapine have been associated with high leptin levels in SMI. However, the link between inflamm…

  • Sex-Specific Effect of Serum Lipids and Body Mass Index on Psychotic Symptoms, a Cross-Sectional Study of First-Episode Psychosis Patients

    Open Access•Priyanthi B Gjerde, Carmen Simonsen et al.•ARTICLE•Frontiers in Psychiatry•2021

    Background: Schizophrenia is a disorder with considerable heterogeneity in course and outcomes, which is in part related to the patients' sex. Studies report a link between serum lipids, body mass index (BMI), and therapeutic response. However, the role of sex in these relationships is poorly understood. In a cross-sectional sample of first-episode psychosis (FEP) patients, we investigated if the relationship between serum lipid levels (total cho…

  • Genetic loci shared between major depression and intelligence with mixed directions of effect

    Open Access•Shahram Bahrami, Alexey A Shadrin et al.•ARTICLE•Nature Human Behaviour•2021•References: 45

  • Childhood Trauma Is Nominally Associated With Elevated Cortisol Metabolism in Severe Mental Disorder

    Open Access•Monica Aas, Torill Ueland et al.•ARTICLE•Frontiers in Psychiatry•2020

    Our study indicates that childhood physical abuse is associated with elevated cortisol metabolism (5β-reductase) in adults with a SZ or BD disorder. However, our study did not support cortisol metabolism as a mediator between childhood trauma experiences and cognitive function within these disorders

  • Atherogenic Lipid Ratios Related to Myeloperoxidase and C-Reactive Protein Levels in Psychotic Disorders

    Open Access•Elina J Reponen, Ingrid Dieset et al.•ARTICLE•Frontiers in Psychiatry•2020

    Our findings suggest that low-grade inflammation and abnormal neutrophil activation may cause increased CVD risk in patients with psychotic disorders. These mechanisms should be further examined to determine the potential for development of novel risk evaluation strategies

  • Improving the precision of intranasal oxytocin research

    Open Access•Adriano Winterton, Lars T Westlye et al.•ARTICLE•Nature Human Behaviour•2020•References: 146

  • Predictors for Antipsychotic Dosage Change in the First Year of Treatment in Schizophrenia Spectrum and Bipolar Disorders

    Open Access•Petter Andreas Ringen, Elina J Reponen et al.•ARTICLE•Frontiers in Psychiatry•2019

    Background: Use of antipsychotic medication is central in the treatment of psychotic disorders. However, there is limited knowledge about prescription practice of antipsychotics in the critical early phase of these disorders. Clinical guidelines recommend low dosages, but no discontinuation of antipsychotic medication during the first year of treatment in first episode patients. The main aim of this study was to identify clinical predictors for d…
