One possible solution to this is to move to a multi-dimensional model of mental illness, as has been proposed by the Research Domain Criteria and Hierarchical Taxonomy of Psychopathology frameworks. In this study, we explored the dimensional structure of psychotic disorders. We focused on the question whether combining measures of psychosis with cognitive and depression-related measures results in meaningful, clinically relevant, and valid latent dimensions in a sample of early psychosis (n = 113) and chronic schizophrenia patients (n = 43, total n = 156). We used exploratory factor analysis to identify the symptom dimensions in the Lausanne Psychosis data, a multi-modal prospective data set that includes a broad behavioral assessment of patients diagnosed with psychotic disorders. We evaluated the validity of these dimensions by regressing them to several functioning measures. Our analysis revealed three dimensions: Cognition, Depression/Negative, and Thought Disorder, explaining 49.2% of the variance. They were related to measures of functioning, the R² ranging between 0.38 and 0.42.

The purpose of this study was to investigate the relationship between the neutrophil-to-lymphocyte ratio (NLR), a marker of inflammation, and the clozapine concentration-to-dose (C/D) ratio during clozapine titration. We retrospectively investigated the medical records of all patients at Nozoe Hills Hospital who met the following criteria: 1) patients with schizophrenia who were first treated with clozapine between April 2020 and July 2024 and 2) patients for whom clozapine blood levels were measured for at least two consecutive weeks after the start of clozapine treatment. The study included 143 blood samples from 28 patients collected within 6 weeks of starting clozapine treatment. A linear mixed model with random intercepts was used to determine the correlation between the clozapine C/D ratio and NLR in samples repeatedly measured within an individual. Fixed effects for the C/D ratio included NLR, week, and the interaction between NLR and week. A significant fixed effect of NLR on C/D ratio was observed (estimate: 0.70; 95% confidence interval: 0.47-0.92; P < 0.0001). The fixed effect of NLR was attenuated over time due to a significant negative interaction between NLR and week. The fixed effect of NLR remained significant even after excluding the six patients who had fever during clozapine titration. This study suggests a positive correlation between the C/D ratio and NLR during clozapine titration.

In the present study, we aimed to describe and analyze the baseline results of this prospective cohort. The prospective cohort study enrolled participants with recent-onset schizophrenia (planned: n = 100), chronic schizophrenia (planned: n = 200), and controls for recent-onset patients (planned: n = 100) in the North Denmark Region from 2015-2019. We included 70 patients with recent-onset schizophrenia (mean age, 24.5 years; males, 54%; mean illness duration, 1 year), 165 patients with chronic schizophrenia (mean age, 49.5 years; males, 57%; mean illness duration, 21.1 years), and 85 controls for recent-onset patients (mean age, 24.4 years; males, 53%). At baseline, cardiovascular risk factors were highly prevalent in patients with schizophrenia (metabolic syndrome: 60%, hypercholesterolemia: 13%, diabetes: 13%, hypertension: 4%). Conversely, the prevalence of manifest cardiac disease, including heart failure, coronary artery disease, and atrial fibrillation/flutter was overall low (~1%). In conclusion, point-prevalences of cardiovascular risk factors were relatively high in patients with schizophrenia, while severe cardiac disease was less pronounced at baseline.

{"title":"Long-term outcomes of Aripiprazole long-acting injectable: a 10-year mirror image study of patient acceptability and treatment effectiveness.","authors":"Joshua Barnett, Sofia Pappa","doi":"10.1038/s41537-025-00637-7","DOIUrl":"10.1038/s41537-025-00637-7","url":null,"abstract":"<p><p>Relapses are frequent in schizophrenia and other psychotic disorders. While long-acting injectable antipsychotics (LAIs) are effective in preventing hospital admissions and improving adherence and patient outcomes, they are still under-utilised. Furthermore, evidence from newer formulations and longitudinal studies, despite their commonly long-term use, remains limited. To address this scarcity of data, this study aims to evaluate the long-term effectiveness and acceptability of once-monthly Aripiprazole long-acting injectable (ALAI), the only third-generation antipsychotic available in long-acting formulation. In this pragmatic, independent, ten-year mirror-image study conducted within a large urban mental health service in London, UK, we assessed hospital admission rates and treatment retention over 5 years following ALAI initiation in a naturalistic adult cohort. Frequency and length of hospitalisations in the 5 years pre- and post-initiation were recorded using electronic records, as were discontinuation rates and reasons. Separate analyses were performed comparing outcomes between treatment completers and discontinuers, as well as between those with schizophrenia vs other diagnoses. In total, 135 patients were included in the study (63% with Schizophrenia, 37% with other diagnoses). The discontinuation rate was 47% at 5 years (23.7%, 13.6%, 7.9%, 7.3% and 5.3% in years 1 to 5 respectively). Among the 53% who completed 5 years of ALAI treatment, we observed an 88.5% reduction in mean number (1.57 to 0.18, p < 0.001) and a 90% reduction in mean length of hospitalizations compared to 5 years pre-ALAI initiation (103 to 10 days, p < 0.0001). Median admissions and length fell from 1 to 0 and 68 to 0 days (p < 0.001), respectively. In contrast, discontinuers (47%) exhibited inferior outcomes and showed only a 29.9% reduction in admissions over 5 years. Patients were more likely to discontinue due to poor compliance and ineffectiveness and rarely due to tolerability issues. Apart from switching to ALAI from another LAI, there were no major clinical or demographic predictors of treatment continuation. Outcomes were consistent independent of diagnosis. Potential confounders however must not be overlooked, such as the exclusion of a large number of patients due to strict eligibility criteria as well as changes to healthcare policy over the study period. This is the first study to report 5-year hospitalisation and treatment persistence outcomes with ALAI. Its sustained use was associated with substantial reductions in hospital use, with 85% of completers requiring no further admissions, compared to 30% of discontinuers. These real-world findings support the long-term value of ALAI and may help address common barriers to LAI adoption in clinical decision-making.</p>","PeriodicalId":74758,"journal":{"name":"Schizophrenia (Heidelberg, Germany)","volume":"11 1","pages":"92"},"PeriodicalIF":3.0,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12185697/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144478181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated cortical excitability and plasticity in 30 patients with schizophrenia (15 TRS, 15 non-TRS) and 21 controls using transcranial magnetic stimulation (TMS).
