Efficacy, tolerability, and safety of xanomeline-trospium chloride for schizophrenia: A systematic review and meta-analysis.

The United States Food and Drug Administration approved xanomeline-trospium combination for schizophrenia on September-26-2024. We conducted a PRISMA 2020-compliant systematic review with random-effects meta-analysis on the efficacy and safety of xanomeline-trospium in randomized controlled trials in patients with schizophrenia (MEDLINE, EMBASE, Cochrane, PsycINFO, October-01-2024). Co-primary outcomes were Positive And Negative Syndrome Scale (PANSS) total score (standardized mean difference=SMD), and all-cause discontinuation (risk ratio=RR).

Triangulating evidence from the GALENOS living systematic review on trace amine-associated receptor 1 (TAAR1) agonists in psychosis.

Background: Trace amine-associated receptor 1 (TAAR1) agonists offer a new approach, but there is uncertainty regarding their effects, exact mechanism of action and potential role in treating psychosis.

Aims: To evaluate the available evidence on TAAR1 agonists in psychosis, using triangulation of the output of living systematic reviews (LSRs) of animal and human studies, and provide recommendations for future research prioritisation.

Method: This study is part of GALENOS (Global Alliance for Living Evidence on aNxiety, depressiOn and pSychosis).

Efficacy and acceptability of pharmacological interventions for tardive dyskinesia in people with schizophrenia or mood disorders: a systematic review and network meta-analysis.

Tardive Dyskinesia (TD) can occur in people exposed to dopamine receptor antagonists (DRAs). Its clinical management remains challenging. We conducted a systematic review/random-effects network meta-analysis (NMA) searching PubMed/MEDLINE/PsycINFO/ClinicalTrials.

EPA guidance on lifestyle interventions for adults with severe mental illness: A meta-review of the evidence.

There is growing interest in lifestyle interventions as stand-alone and add-on therapies in mental health care due to their potential benefits for both physical and mental health outcomes. We evaluated lifestyle interventions focusing on physical activity, diet, and sleep in adults with severe mental illness (SMI) and the evidence for their effectiveness. To this end, we conducted a meta-review and searched major electronic databases for articles published prior to 09/2022 and updated our search in 03/2024.

Influences of sex and gender on the associations between risk and protective factors, brain, and behavior.

Risk and protective factors for psychiatric illnesses are linked to distinct structural and functional changes in the brain. Further, the prevalence of these factors varies across sexes and genders, yet the distinct and joint effects of sex and gender in this context have not been extensively characterized. This suggests that risk and protective factors may map onto the brain and uniquely influence individuals across sexes and genders.

Reconsidering evidence for psychedelic-induced psychosis: an overview of reviews, a systematic review, and meta-analysis of human studies.

Background: Persons with schizophrenia are excluded from psychedelic-assisted therapy due to concerns about the risk of triggering or worsening psychosis. However, there is limited meta-analytic data on the risk of psychedelic-induced psychosis in individuals with pre-existing psychotic disorders.

Methods: We conducted a systematic review, meta-analysis, and overview of reviews to assess the incidence of psychedelic-induced psychosis and symptom exacerbation in schizophrenia.

Attention Deficit Hyperactivity Disorder Among Youth at Clinical High Risk of Psychosis.

Background: Attention Deficit Hyperactivity Disorder (ADHD) affects a significant proportion of the population and is associated with numerous adverse outcomes including lower educational attainment, occupational challenges, increased substance use, and various mental health issues including psychosis. This study examined the demographic, clinical, cognitive, social cognitive, and functional differences between youth at clinical high-risk (CHR) for psychosis with and without comorbid ADHD.

Method: Data were drawn from the North American Prodrome Longitudinal Studies (NAPLS2 and NAPLS3), which included 764 and 710 CHR individuals, respectively.

Collaborative Outcomes Study on Health and Functioning During Infection Times (COH-FIT): Global and Risk-Group Stratified Course of Well-Being and Mental Health During the COVID-19 Pandemic in Adolescents.

Objective: To identify the COVID-19 pandemic impact on well-being/mental health, coping strategies, and risk factors in adolescents worldwide.

Method: This study was based on an anonymous online multi-national/multi-language survey in the general population (representative/weighted non-representative samples, 14-17 years of age), measuring change in well-being (World Health Organization-Five Well-Being Index [WHO-5]/range = 0-100) and psychopathology (validated composite P-score/range = 0-100), WHO-5 <50 and <29, pre- vs during COVID-19 pandemic (April 26, 2020-June 26, 2022). Coping strategies and 9 a priori- defined individual/cumulative risk factors were measured.

"Short" Versus "Long" Duration of Untreated Psychosis in People with First-Episode Psychosis: A Systematic Review and Meta-Analysis of Baseline Status and Follow-Up Outcomes.

Background And Hypothesis: Duration of untreated psychosis (DUP) has been linked to worse mental health outcomes in psychotic disorders. We meta-analytically studied the relationship between "long" vs. "short" DUP and mental health outcomes.

Impact of Antipsychotic Medications on Weight Gain and Eating Disorder-Related Psychopathology in Adult Inpatients with Anorexia Nervosa.

Introduction: The impact of antipsychotic use on weight gain and eating disorder-related psychopathology in adult inpatients with anorexia nervosa (AN) is unclear.

Methods: Consecutively hospitalized adults with AN were retrospectively analyzed. Co-primary outcomes were body mass index (BMI) and weekly weight change.

Mismatch Negativity as an Index of Auditory Short-Term Plasticity: Associations with Cortisol, Inflammation, and Gray Matter Volume in Youth at Clinical High Risk for Psychosis.

Mismatch negativity (MMN) event-related potential (ERP) component reduction, indexing N-methyl-D-aspartate receptor (NMDAR)-dependent auditory echoic memory and short-term plasticity, is a well-established biomarker of schizophrenia that is sensitive to psychosis risk among individuals at clinical high-risk (CHR-P). Based on the NMDAR-hypofunction model of schizophrenia, NMDAR-dependent plasticity is predicted to contribute to aberrant neurodevelopmental processes involved in the pathogenesis of schizophrenia during late adolescence or young adulthood, including gray matter loss. Moreover, stress and inflammation disrupt plasticity.

Validation and psychometric properties of the bipolar prodrome symptom interview and scale-full prospective Chinese version to assess individuals at risk for bipolar disorder.

Background: Bipolar disorder (BD) is a chronic, severe mental illness with a significant socio-economic burden. The early recognition of BD requires reliable and valid instruments.

Objective: We evaluated the psychometric attributes of the Bipolar Prodrome Symptom Interview and Scale-Full Prospective (BPSS-FP)-Chinese version.

Excess mortality and life-years lost in people diagnosed with depression: A 20-year population-based cohort study of 126,573 depressed individuals followed for 1,139,073 persons-years.

Depression is associated with premature mortality, but evidence is mainly derived from Western countries. Very limited research has evaluated shortened lifespan in depression using life-years-lost (LYLs), a recently developed mortality metric taking into account the illness onset for life expectancy estimation. Temporal trends of differential mortality gap are understudied.

Cognitive-Behavioural Social Skills Training: Mediation of Treatment Outcomes in a Randomized Controlled Trial for Youth at Risk of Psychosis: L'entraînement aux compétences sociales cognitivo-comportementales : variables médiatrices des résultats thérapeutiques dans le cadre d'un essai clinique randomisé pour les jeunes présentant un risque de psychose.

Objectives: Currently, there are no effective treatments for functional outcomes (i.e., role and social) and negative symptoms for youth at clinical high-risk (CHR) for psychosis.

Comparing two transitioning strategies to paliperidone palmitate once-every-6-months.

Background: A double-blind, randomized, active-controlled, parallel-group, noninferiority trial (NCT03345342) demonstrated that paliperidone palmitate once-every-6-months (PP6M) was noninferior to paliperidone palmitate once-every-3-months (PP3M) in preventing relapse in clinically stable adults with schizophrenia. This post hoc analysis assessed efficacy and safety following transition to PP6M from paliperidone once-monthly (PP1M) versus PP3M.

Methods: Adults with schizophrenia who were clinically stable on moderate/high doses of PP1M or PP3M were randomly assigned 1:2 to dorsogluteal PP3M or PP6M treatment for 12 months.

Peripartum allopregnanolone blood concentrations and depressive symptoms: a systematic review and individual participant data meta-analysis.

Neuroactive steroids including allopregnanolone are implicated in the pathophysiology of peripartum depressive symptoms (PDS). We performed a systematic review searching PubMed/Embase/PsychInfo/Cinhail through 08/2023 (updated in 07/2024), and conducted a random-effects meta-analysis of studies comparing allopregnanolone blood concentrations in women with versus without PDS at various timepoints during the 2 and 3 trimester and the postpartum period, calculating standardized mean differences (SMDs) and 95% confidence intervals (CIs). Meta-regression and subgroup analyses included age, diagnoses of affective disorders before pregnancy, antidepressant treatment, analytical methods, and sample type.
