Objective: This paper examines, using data from the Cantabria First Episode Schizophrenia Study, the usefulness of subdividing, using a cluster analysis technique, this schizophrenia population into subgroups with similar symptoms profiles in terms of SANS and SAPS.
Method: Diagnostic characteristics were determined using the Present State Examination (PSE-9) and the SANS/SAPS. Premorbid adjustment was assessed using a scale developed combining the Gittelman and Klein's Scales, and the Goldstein's scales. Social Adjustment was evaluated using the WHO-DAS. In addition clinical histories were used to assess the patients' clinical course.
Results: Our schizophrenic patients could be subtyped into four categories: negative, positive non-paranoid, simple and disorganized schizophrenia. There is an absence of significant association between the majority of the variables investigated and the four-cluster model.
Conclusion: Even though our sample could be subtyped into different categories, the model does not show predictive power according to the 3-year follow-up data.

Objective: To investigate the association between ambient coarse particulate matter (PM) pollution and risk of acute schizophrenia episodes.
Methods: A time-stratified case-crossover study with a two-stage analytical approach was conducted to investigate the association between ambient PM pollution and schizophrenia admissions (an indicator for acute schizophrenia episodes) across 259 Chinese cities of prefecture-level or above during 2013-2017. A conditional logistic regression model was constructed to estimate city-specific changes in hospital admissions for schizophrenia associated with per interquartile range (IQR) increase in ambient PM, and the overall associations were obtained by pooling the city-specific associations using the random-effects model.

Objective: Functional magnetic resonance imaging data pose significant challenges due to their inherently noisy and complex nature, making traditional statistical models less effective in capturing predictive features. While deep learning models offer superior performance through their non-linear capabilities, they often lack transparency, reducing trust in their predictions. This study introduces the Time Reversal (TR) pretraining method to address these challenges.

Background: The best pharmacological treatment practices for relapse prevention in patients with first-episode schizophrenia are unclear. We aimed to assess different treatment strategies used before and after the first relapse, and their associations with subsequent relapse risk.
Methods: In this population-based cohort study, we enrolled individuals (aged ≤45 years) with first-episode schizophrenia who were hospitalised and subsequently relapsed between 1996 and 2014 from the nationwide Finnish Hospital Discharge Register.
Basic self-disorders may play a role in the development of depression in schizophrenia: a seven-year follow-up study.

Introduction: Depression is the most common co-morbid psychiatric disorder in patients with schizophrenia and has a negative effect on functional outcomes and quality of life. There are several possible pathways leading to depressive symptoms in schizophrenia. Self-disorders are disturbances in the deepest, pre-reflective level of the self and are suggested to be core features of schizophrenia.
