Comparative cardiometabolic safety and effectiveness of aripiprazole in people with severe mental illness: A target trial emulation.
PLoS Med
January 2025
Division of Psychiatry, University College London, London, United Kingdom.
Background: There is limited and conflicting evidence on the comparative cardiometabolic safety and effectiveness of aripiprazole in the management of severe mental illness. We investigated the hypothesis that aripiprazole has a favourable cardiometabolic profile, but similar effectiveness when compared to olanzapine, quetiapine, and risperidone.
Methods And Findings: We conducted an observational emulation of a head-to-head trial of aripiprazole versus olanzapine, quetiapine, and risperidone in UK primary care using data from the Clinical Practice Research Datalink.
Effect of antipsychotics on the focal adhesion pathway.
World J Biol Psychiatry
January 2025
School of Medicine, IMPACT, Institute for Innovation in Physical and Mental Health and Clinical Translation, Deakin University, Geelong, Australia.
Unlabelled: Focal adhesions and their dynamic nature are essential for various physiological processes, including the formation of neurites, synaptic function and plasticity. Alterations in these processes have been associated with schizophrenia and bipolar disorder.
Objectives: This study aimed to explore the impact of pharmacological treatments used for bipolar disorder and schizophrenia on the expression of genes involved in the focal adhesion pathway, addressing a gap in understanding the interaction between medication effects and disease pathophysiology.
Distinct Effects of Olanzapine Depot Treatment on Behavior and Muscarinic M1 Receptor Expression in the Triple-Hit Wisket Rat Model of Schizophrenia.
Genes Brain Behav
February 2025
Department of Physiology, Albert Szent-Györgyi Medical School, University of Szeged, Szeged, Hungary.
This study aimed to characterize the triple-hit schizophrenia-like model rats (Wisket) by the assessment of (1) behavioral parameters in different test conditions (reward-based Ambitus test and HomeManner system) for a prolonged period, (2) cerebral muscarinic M1 receptor (M1R) expression, and (3) the effects of olanzapine treatment on these parameters. Wistar (control) and Wisket rats were injected for three consecutive weeks with olanzapine depot (100 mg/kg) and spent 4 weeks in large cages with environmental enrichment (HomeManner). The vehicle-treated Wisket rats spent longer time awake with decreased grooming activity compared to controls, without changes in their active social behavior (sniffing, playing, fighting) obtained in HomeManner.

Tijdschr Psychiatr
January 2025
Bipolar disorder (BD) frequently occurs in children and adolescents, but pharmacological treatment in this group presents significant challenges. Clinicians often struggle to find appropriate treatment guidelines due to the primary focus of current guidelines on adults, leaving specific recommendations for the acute and maintenance treatment of BD in children and adolescents either insufficient or entirely absent. This gap is partly due to the lack of targeted studies in this age group, leading practitioners to rely on clinical experience and studies conducted in adults.

Psychiatry Clin Neurosci
January 2025
Department of Psychiatry, Nagoya University Graduate School of Medicine, Nagoya, Japan.
Aim: This study aimed to explore the comparative risks for dystonia among different second-generation antipsychotics (SGAs), the influence of sex, and the relationship between the time-to-onset of dystonia and its outcomes.
Methods: We analyzed data from the Japanese Adverse Drug Event Report database from April 2004 to November 2023. Cases involving oral SGAs, excluding clozapine, were extracted.
