Summary: Hippocampal volume and morphological changes are core features of schizophrenia. In early-stage psychosis, the hippocampus shows significant volumetric decrease and shape changes. However, these changes are not related to clinical outcomes.

Summary: This study analyzed the mitochondrial metabolism in the early stage of type 1 diabetes, and found that the mitochondrial membrane potential and ATP production in the heart of diabetic animals were similar to the control group, but Mn-SOD activity decreased and H2O2 production increased. This suggests the presence of mitochondrial dysfunction in the early stage of type 1 diabetes, but without irreversible damage.

Summary: This study found that reduced hippocampal volume is a brain morphological feature of psychiatric conditions. It also observed associations between hippocampal volume and hippocampal functional connectivity with the inferior parietal lobe and thalamus. The results suggest that the functional connectivity of the hippocampus with the temporoparietal junction within the default mode network is sensitive to hippocampal volume.

Summary: Mapping the semantic content of speech as a network can improve our understanding of formal thought disorder in psychosis. Using the algorithm netts, we created semantic speech networks for a general population and clinical sample, finding that patients with psychosis had smaller and more fragmented networks, which were related to negative symptoms and thought and language index scores.

Summary: In this study, the impact of aSyn on microtubule organization was investigated in cell models and patient-derived neurons. The results suggest that aSyn aggregation interferes with microtubule organization, leading to impaired neuritic phenotypes in Parkinson's disease.

Summary: This study aimed to describe the distribution of glutathione peroxidase 4 (GPx4) in rat oocytes, preimplantation embryos, and female genital organs. The results showed that GPx4 was expressed in oocytes, preimplantation embryos, and various tissues of female genital organs, with differences in expression patterns.

Summary: The study found significant impairment of social memory in mice with hearing loss, but no significant differences were seen in tests such as novel object recognition, Morris water maze, and locomotion in the open field. Therefore, the study demonstrates that hearing input is required for the formation of social memory, and hearing stimuli play an important role in the development of normal cognitive ability.

Summary: This study found significant differences in verbal memory, symptoms, and brain structure between different sexes in FEP patients. Verbal memory deficits and core psychotic symptoms in male patients were associated with changes in frontal and temporal cortical thickness, as well as reductions in CA2/3 hippocampal subfield and fornix volumes. In female patients, fewer negative/depressive symptoms were related to a less pronounced cortical thickness pattern and more diffuse reductions in hippocampal white matter regions.

Summary: Chronic intermittent alcohol exposure affects the microstructural integrity of the fimbria/fornix, reducing the communication between the hippocampus and prefrontal cortex. This communication disturbance impairs the extinction of maladaptive memories, leading to decreased cognitive flexibility.

Summary: This study investigated the relationship between cerebral blood flow (CBF) and white matter structure in early-stage schizophrenia patients. The findings revealed an inverse correlation between CBF and fractional anisotropy (FA) in the corpus callosum, as well as a positive correlation between FA and processing speed. Mediation analysis showed that the effect of FA on processing speed was mediated by CBF.

Summary: Using a multimodal magnetic resonance imaging approach, this study investigated the anomalies in thalamic structure in early phase psychosis and chronic schizophrenia. The results revealed widespread microstructural alterations in thalamus associated with white matter integrity changes. Furthermore, localized changes were observed in specific subregions, and these alterations varied in nature across different subregions.

Summary: This meta-analysis examines the association between childhood adversity (CA) and functional outcomes in individuals with psychotic disorders. The findings demonstrate a negative relationship between CA and general functioning, as well as social functioning, indicating that emotional and physical neglect have the most significant impact on functional outcomes.

Summary: This study aims to provide a comprehensive review and meta-analysis of the diagnosis, prognosis, and treatment of negative symptoms in children and adolescents with early-onset psychosis (EOP) and those at clinical high risk for psychosis (CHR-P). The findings indicate that negative symptoms are common in children and adolescents at early stages of psychosis, particularly in those at CHR-P, and are associated with poor outcomes. Therefore, further intervention research is needed to provide evidence-based treatments.

Summary: Redox biology and immune signaling are important in brain function and are implicated in neuropsychiatric conditions such as schizophrenia, bipolar disorder, autism, and epilepsy. This article reviews the literature on these topics, discusses their implications for the pathophysiology of schizophrenia, and explores the potential for novel treatment interventions targeting redox and immune signaling.

Summary: Due to its heterogeneity, schizophrenia requires new diagnostic tools based on mechanistic biomarkers for early detection. The complex interaction between genetic and environmental risk factors may lead to NMDAR hypofunction, inflammation, and redox dysregulation, ultimately resulting in oxidative stress. Using computational analysis, the study examined the expression of 76 genes involved in these systems in skin-fibroblasts from early psychosis patients and controls. The study also investigated the GAG trinucleotide polymorphism in the gclc gene to assess the genetic risk related to redox dysregulation. The findings suggest the importance of oxidative stress and genetic factors in schizophrenia, and machine learning approaches show promise for early detection.

Summary: Studies have found that DNA methylation is sensitive to childhood adversity in psychotic disorders, but it is unclear whether it mediates the association between childhood adversity and psychosis. This study found that childhood adversity was associated with psychosis, but no specific CpG sites were found to mediate the association. However, there were differentially methylated probes associated with genes previously linked to psychosis.

Summary: This study investigates the impact of interactions between manic, depressive, and paranoid symptoms on suicidality in first-episode affective psychoses. The results indicate that the combination of either manic and paranoid symptoms or depressive and paranoid symptoms is significantly associated with an increased risk of suicide. However, the combination of depressive and manic symptoms shows a significant negative association with suicidal thoughts.

Summary: The measurement of patient-to-staff violence (PSV) is crucial for institutions to prevent negative outcomes and provide effective interventions. However, there is limited knowledge about how well different approaches to measuring PSV adapt to different types of psychiatric wards. Further investigation is needed to understand the role of gender and age in PSV.
