[Experiences and subjective transformations: suffering and coercion in the use of psychotropic drugs in psychiatric treatment in Chile].

This article analyzes the impact of psychotropic drug use on individuals diagnosed with schizophrenia, bipolar affective disorder, and severe depression in Chile. Using a qualitative narrative approach, the experiences of 25 patients from 2018 to 2021 are examined. Participants describe how these medications, while effective in symptom control, generate psychological suffering and a sense of coercion in daily life.

Genetic analysis of psychosis Biotypes: shared Ancestry-adjusted polygenic risk and unique genomic associations.

The Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) created psychosis Biotypes based on neurobiological measurements in a multi-ancestry sample. These Biotypes cut across DSM diagnoses of schizophrenia, schizoaffective disorder, and bipolar disorder with psychosis. Two recently developed post hoc ancestry adjustment methods of Polygenic Risk Scores (PRSs) generate Ancestry-Adjusted PRSs (AAPRSs), which allow for PRS analysis of multi-ancestry samples.

[Long-term courses of bipolar disorders].

Background: Bipolar disorder (short: BD) is a severe illness with very heterogeneous trajectories. While some of the patients show no or hardly any long-term impairments, other affected individuals show substantial neurocognitive deficits with a clear decline in psychosocial functioning. Which factors influence the course of the disease is the subject of current research efforts.

A systematic review of measures of mania and depression in older people with bipolar disorder.

Background: Previous research on bipolar disorder (BD) primarily focused on younger adults, with limited research on older adults. This systematic review is the first to investigate how mania and depression are measured in older adults with BD.

Methods: The searches were completed in April 2024 using the databases PsycINFO, CINAHL Plus, MEDLINE, and Embase.

SARS-CoV-2 infection and COVID-19 outcomes across mental disorders and the role of sex: A register-based study from Catalonia.

Introduction: This study investigated the risk of SARS-CoV-2 infection and severe COVID-19 outcomes among different mental health diagnoses and the role of sex in these associations.

Methods: Using electronic records from Catalonia, we identified adults receiving mental health care from 2017-2019 with diagnoses of non-affective psychosis (NAP), bipolar disorder (BD), depressive disorder (DEP), stress-related disorders, neurotic/somatoform disorders (NSD), and substance misuse (SUB) (exposed). The outcomes assessed were SARS-CoV-2 infection, COVID-19 hospitalization, and COVID-19-related death, compared to matched individuals without these mental disorders (unexposed).

Individualized psychiatric care: integration of therapeutic drug monitoring, pharmacogenomics, and biomarkers.

Personalized treatment optimization considers individual clinical, genetic, and environmental factors influencing drug efficacy and tolerability. As evidence accumulates, these approaches may become increasingly integrated into standard psychiatric care, potentially transforming the treatment landscape for mental health disorders. While personalized treatment optimization shows promise in enhancing therapeutic outcomes and minimizing adverse effects, further research is needed to establish its clinical utility and cost-effectiveness across various psychiatric disorders.

Association between allostatic load and cardiac structural and functional abnormalities in young adults with serious mental disorders.

Objective: Allostatic load refers to the pathophysiological consequences of uncompensated adaptation to chronic stress. Few studies have investigated the effect of allostatic load on cardiac health in patients with serious mental disorders (SMDs), a population at high risk of cardiac mortality. Herein we evaluated associations between allostatic load and cardiac structure and function in young adults with SMDs.

SKA2 enhances stress-related glucocorticoid receptor signaling through FKBP4-FKBP5 interactions in neurons.

Genes involved in regulating the hypothalamic-pituitary-adrenal (HPA) axis, including the glucocorticoid receptor (GR), are linked to various stress-related psychopathologies including bipolar disorder as well as other mood and trauma-related disorders. The protein product of the cell cycle gene, is a GR interaction partner in peripheral cells. However, the precise roles of SKA2 in stress and GR signaling in the brain, specifically in nonreplicating postmitotic neurons, and its involvement in HPA axis regulation remain unclear.

Physiologically based pharmacokinetic modeling to predict the effect of risperidone on aripiprazole pharmacokinetics in subjects with different CYP2D6 genotypes and individuals with hepatic impairment.

Background: Aripiprazole and risperidone, widely used atypical antipsychotics, are commonly adjunctively prescribed in clinical practice. When aripiprazole was combined with risperidone, the genotype of drug-metabolizing enzymes and liver impairment may lead to complex pharmacokinetic changes. The Physiologically Based Pharmacokinetic (PBPK) model can predict the influence of these factors on plasma concentration and optimize dosage regimens.

Exacerbation of neuropsychiatric symptoms in an adult male with influenza A virus treated with oseltamivir.

Oseltamivir (Tamiflu) package labeling has a warning for neuropsychiatric adverse events (NPAE), most commonly in children and adolescents, especially males. There are several case reports of NPAE in adults treated with oseltamivir, but few document patients with preexisting neuropsychiatric conditions without additional contributing factors. This case report describes a 22-year-old male with a history of bipolar disorder, depression, and attention-deficit/hyperactivity disorder who had been stable on his medication regimen before experiencing sudden worsening of symptoms after the initiation of oseltamivir.

Cognitive Remediation in Patients With Bipolar Disorder: A Randomized Trial by Sequential tDCS and Navigated rTMS Targeting the Primary Visual Cortex.

Background: Non-invasive brain stimulation (NIBS), such as transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS), has emerged as a promising alternative in the precise treatment of clinical symptoms, such as the cognitive impairment of bipolar disorder (BD). Optimizing the neurocognitive effects by combining tDCS and rTMS to strengthen the clinical outcome is a challenging research issue.

Objective: In this randomized, controlled trial, we first combined tDCS and neuronavigated rTMS targeting the V1 region to explore the efficacy on neurocognitive function in BD patients with depressive episodes.

Narrative medicine has the potential to bring about positive impacts on the practitioner-patient relationship and on patient outcomes. The authors carried out a pilot study investigating the impact of narrative medicine on residents' stigma toward bipolar disorder.

The emerging role of long non-coding RNA SOX2-OT in cancers and non-malignant diseases.

SOX2 overlapping transcript (SOX2-OT) is a long non-coding RNA located at chromosome 3q26.33 in humans. Convincing data confirm that SOX2-OT is evolutionarily conserved and plays a significant role in various malignant and non-malignant diseases.

Error monitoring and response inhibition in adolescents with bipolar disorders: An ERP study.

Cognitive control develops throughout adolescence, a high-risk period for bipolar disorders (BD) onset. Despite neurobehavioral abnormalities in adults with BD, there is minimal research investigating deviations in cognitive control in adolescents with BD. Cognitive control involves numerous processes.

Mood instability and risk of gastrointestinal diseases - a univariable and multivariable mendelian randomization study.

Background: Mood instability, characterized by sudden and unpredictable mood shifts, is prevalent in psychiatric disorders and as a personality trait. Its association with gastrointestinal diseases has been recognized but remains poorly understood in terms of causality.

Methods: This study aims to investigate the causal relationship between mood instability and a spectrum of gastrointestinal diseases by univariable and multivariable mendelian randomization analysis.

In a letter critiquing our manuscript, Takefuji highlights general pitfalls in machine learning, without directly engaging with our study. The comments provide generic advice rather than a specific critique of our methods or findings. Despite raising important topics, the concerns reflect standard risks in machine learning, which we were aware of and explicitly addressed in our analyses.

Model-informed precision dosing of quetiapine in bipolar affective disorder patients: initial dose recommendation.

Objective: Bipolar affective disorder (BAD) is a mood disorder with high morbidity and mortality. Quetiapine can be used in the treatment of patients with BAD; however, the precise administration regimen of quetiapine in these patients is still unknown. In this study, a population pharmacokinetic (PPK) model of quetiapine in patients with BAD was constructed based on model-informed precision dosing (MIPD) and real-world clinical data and an optimal initial dose of quetiapine in these patients was recommended.

Nanomolar detection of lurasidone hydrochloride in pharmaceutical formulations (Serodopamoun®) and spiked urine using a PVC/imprinted polymer/MWCNTs layer deposited onto polyaniline-coated screen-printed electrodes.

This study developed potentiometric sensors for detecting lurasidone HCl (LSH), a vital drug for treating schizophrenia and bipolar I disorder, in pharmaceutical formulations and biological samples. The sensors are based on screen-printed electrodes (SPE) modified with a molecularly imprinted polymer (MIP) synthesized using lurasidone as a template, 1-vinyl-2-pyrrolidine (VP) as a functional monomer, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, and benzoyl peroxide as an initiator. The SPE was further modified with a conductive polyaniline (PANI) film and a polyvinyl chloride (PVC) layer containing MIP as an ionophore and multiwalled carbon nanotubes (MWCNT) as a transducing material along with 2-nitrophenyl octyl ether (2-NPOE) as plasticizer.

Method: We conducted a 16-week, double-blind, randomized, placebo-controlled investigation of quetiapine plus TPM (median dose = 208 mg) vs quetiapine plus placebo in adolescents with bipolar I and cannabis use disorder. All subjects participated in a Motivational Interview and Compliance Enhancement Therapy.

Agomelatine bears promising potential in treating bipolar depression- a systematic review.

Introduction: The controversy of antidepressant use in bipolar depression remains controversial. Agomelatine (AGO) is an effective antidepressant in major depressive disorder (MDD), but its application in bipolar depression was little discussed. We aimed to provide a comprehensive systematic review of clinical evidence from studies examining the efficacy and safety of AGO for bipolar depression.

Exploring autism spectrum disorder and co-occurring trait associations to elucidate multivariate genetic mechanisms and insights.

Background: Autism spectrum disorder (ASD) is a partially heritable neurodevelopmental trait, and people with ASD may also have other co-occurring trait such as ADHD, anxiety disorders, depression, mental health issues, learning difficulty, physical health traits and communication challenges. The concomitant development of ASD and other neurological traits is assumed to result from a complex interplay between genetics and the environment. However, only a limited number of studies have performed multivariate genome-wide association studies (GWAS) for ASD.

Disruption of the gut microbiota-inflammation-brain axis in unmedicated bipolar disorder II depression.

The relationships of the gut microbiota-inflammation-brain axis in depressive bipolar disorder (BD) remains under-elaborated. Sixty-five unmedicated depressive patients with BD II and 58 controls (HCs) were prospectively enrolled. Resting-state functional MRI data of static and dynamic amplitude of low-frequency fluctuation (ALFF) was measured, and abnormal ALFF masks were subsequently set as regions of interest to calculate whole-brain static functional connectivity (sFC) and dynamic functional connectivity (dFC).

Exploring PDE5A upregulation in bipolar disorder: insights from single-nucleus RNA sequencing of human basal ganglia.

Basal ganglia is proposed to mediate symptoms underlying bipolar disorder (BD). To understand the cell type-specific gene expression and network changes of BD basal ganglia, we performed single-nucleus RNA sequencing of 30,752 nuclei from caudate, putamen, globus pallidus, and substantia nigra of control human postmortem brain and 24,672 nuclei from BD brain. Differential expression analysis revealed major difference lying in caudate, with BD medium spiny neurons (MSNs) expressing significantly higher PDE5A, a cGMP-specific phosphodiesterase.
