A total of 635 individuals hospitalized between 2010 and 2013 were followed for 10 years. Mortality rates, causes of death, and risk factors were assessed using Cox regression models and standardized mortality ratios (SMRs).

Violent deaths, including suicides and accidents, accounted for 17.07% of all mortality. The mean age at death was 58.97 years, reflecting a 17-year reduction in life expectancy.

Additionally, we conducted colocalization analyses, replication analyses in blood and at the single-cell level, single-cell gene annotation, developmental trajectory analysis, and various functional assessments. We found that elevated GANC expression in the putamen basal ganglia, nucleus accumbens basal ganglia, cortex, and whole blood was associated with a reduced risk of bipolar disorder (OR, 0.532-0.877; P, 4.04 × 10^-5 to 1.45 × 10^-7), implying that antagonism of GANC by the antidiabetic drug miglitol could increase bipolar risk. Conversely, increased ABCC8 expression in the cortex, cerebellum, cerebellar hemisphere, and VIP- and LAMP5-expressing inhibitory neurons was linked to a higher risk of schizophrenia (OR, 1.054-1.119; P, 1.46 × 10^-3 to 4.42 × 10^-5), suggesting that ABCC8 inhibition by sulfonylureas or glinides may lower the risk of schizophrenia. Colocalization analysis further confirmed the above associations. GANC and ABCC8 displayed specific developmental trajectories, and functional analyses revealed that they affected psychiatric risk through pathways related to potassium ion channels, insulin secretion, and glucose metabolism.

Perinatal insults often co-occur, creating methodological challenges in understanding their impacts on psychosis-spectrum phenotypes. Data-driven approaches to organizing perinatal insults and testing their longitudinal effects on psychotic-like experiences in youth increases ecological validity and translational utility. Using data from 11,417 youth ages 9-14 across five years of the Adolescent Brain Cognitive Development (ABCD) Study, data-driven dimensions of perinatal insults were derived through exploratory factor analysis of thirty-one perinatal insults. Latent growth modeling tested the effect of perinatal insult dimensions on trajectories (baseline, rate-of-change, year-four severity) of distressing psychotic-like experiences. Six dimensions of perinatal insults were observed (substance exposure, obstetric complications, birth complications, postnatal challenges, parental age, medical needs). Substance exposure (β = 0.42, 95% CI [0.20, 0.63]), obstetric complications (β = 0.34, 95% CI [0.08, 0.61]), and parental age (β = 1.00, 95% CI [0.76, 1.22]) were associated with elevated baseline psychotic-like experiences. Perinatal insult dimensions were not associated with increasing rates-of-change in psychotic-like experiences. Medical needs (β = -0.12, 95% CI [-0.20, -0.05]) and parental age (β = -0.11, 95% CI [-0.18, -0.03]) were associated with steeper declines in psychotic-like experiences. Perinatal insult dimensions remained associated with elevated psychotic-like experiences at year-four. Data-driven dimensions of perinatal insults are associated with stably elevated psychotic-like experience trajectories across early adolescence.

Multi-omics data were obtained from a cohort of 87 SZ patients and 70 healthy controls (HCs), including fecal 16S rRNA sequencing, DTI-ALPS index analysis, and cognitive assessments. Correlation and mediation analyses were conducted to explore the relationships among the gut microbiome, DTI-ALPS index, and cognitive performance. Compared to HCs, patients with SZ exhibited significantly lower DTI-ALPS indices in the left, right, and bilateral hemispheres. These indices were positively associated with multiple cognitive domains. In addition, gut microbial dysbiosis was observed in SZ, characterized by a decrease in butyrate-producing bacteria and an increase in pathogenic bacteria. Exploratory analyses further revealed a tripartite link among the key microbial genera, DTI-ALPS indices, and cognitive performance. Notably, the higher abundance of Proteus as well as the lower abundance of Blautia and Faecalibacterium may contribute to poorer cognitive performance, potentially through disruptions in the right DTI-ALPS index.

Substantial alterations in face processing are observed in a wide range of mental disorders, in particular, in schizophrenia (SZ). Individuals with SZ experience difficulties to seeing faces in face-pareidolia images that easily elicit face impression in their typically developing (TD) peers. Here, males with SZ and TD controls performed a task with Arcimboldo-like Face-n-Food face-pareidolia images during MEG recording. The outcome reveals that already at early processing stages, the bursts of gamma oscillations differ between SZ and TD individuals in terms of frequency and topography. When contrasting gamma activity for face responses between TD individuals and SZ, the maximum activation for the frequency range of 40-45 Hz originates from the right LOC. In accord with this, in SZ, an advanced analysis of brain connectivity unfolding over time in the low (40-45 Hz) and high (65-70 Hz) gamma ranges reveals alterations in communication between the right LOC and the social brain. In SZ, early engagement of the right LOC is limited to transmitting signals to higher-order regions, whereas in TD, it also serves as a recipient of sophisticated feedback communication from the higher-order areas of the social brain. This study offers novel insights into altered brain communication and the origins of social cognition deficits in SZ that is characterized by a skewed sex ratio with substantial gender differences in disease manifestation.</p>","PeriodicalId":74758,"journal":{"name":"Schizophrenia (Heidelberg, Germany)","volume":"11 1","pages":"112"},"PeriodicalIF":4.1,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12350684/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144850061","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}
