Whole exome sequencing analysis of susceptibility loci in transgender individuals.

Background: Genetic factors contributing to sex-associated dimorphic brain development may also underlie gender identity-related anxiety disorders.

Aim: To establish a high-throughput whole-exome sequencing (WES) and bioinformatics pipeline for identifying rare variants in sex-dimorphic neural pathways and explore their association with gender identity-related anxiety.

Methods: Peripheral genomic DNA was collected from 23 patients (13 Assigned male at birth (AMAB), 10 Assigned female at birth (AFAB)) presenting with gender identity-related anxiety at Shanghai Mental Health Centre between March 2020 and February 2022.

Brain functional connectivity associated with cognitive deficits in younger patients at first episode of schizophrenia.

Background: Cognitive deficits are a core feature of schizophrenia and are influenced by the age at onset of psychosis. Both preclinical and early-onset schizophrenia patients exhibit abnormalities in the frontal cortex, parahippocampus, precuneus, and hippocampus-regions that are closely associated with cognitive deficits. This study examines whether cognitive-related functional connectivity (FC) within these regions differs in first-episode schizophrenia (FES) patients with varying ages of onset.

A guided internet-delivered mindfulness-based cognitive therapy for insomnia: study protocol for a randomized controlled study.

Background: Chronic insomnia disorder (CID) is highly prevalent and impacts individuals' physiological, psychological and social functions. Although cognitive behavioral therapy for insomnia (CBT-I) is the recommended first-line treatment option for CID, approximately 20% of patients still exhibit limited effectiveness. The literature has shown that mindfulness can benefit CBT-I protocols and that mindfulness-based cognitive therapy (MBCT) is effective in treating insomnia.

Dynamic modular dysregulation in multilayer networks underlies cognitive and clinical deficits in first-episode schizophrenia.

Schizophrenia has been identified to exhibit significant abnormalities in brain functional networks, which are likely to underpin the cognitive and functional impairments observed in patients. Graph theoretical analysis revealed the disrupted modularity in schizophrenia, however, the dynamic network abnormalities in schizophrenia remains unclear. We collected the resting-state functional magnetic resonance imaging data from 82 first-episode schizophrenia (FES) patients and 55 healthy control (HC) subjects.

A generic causality-informed neural network (CINN) methodology for quantitative risk analytics and decision support.

In this paper, we develop a generic framework for systemically encoding causal knowledge manifested in the form of hierarchical causality structure and qualitative (or quantitative) causal relationships into neural networks to facilitate sound risk analytics and decision support via causally-aware intervention reasoning. The proposed methodology for establishing causality-informed neural network (CINN) follows a four-step procedure. In the first step, we explicate how causal knowledge in the form of directed acyclic graph (DAG) can be discovered from observation data or elicited from domain experts.

Association between housework and the risk of dementia among older Chinese adults: a prospective cohort study.

Objectives: Physical activity (PA) is known to improve physical functioning and mental health and to reduce the incidence of dementia. However, studies of the effects of non-recreational PA on the incidence of dementia, especially in East Asian populations, remain limited. In this study, we evaluate the association of doing housework with the risk of dementia among participants in the Chinese Longitudinal Healthy Longevity Survey (CLHLS).

Early Diagnosis of Bipolar Disorder Coming Soon: Application of an Oxidative Stress Injury Biomarker (BIOS) Model.

Early distinction of bipolar disorder (BD) from major depressive disorder (MDD) is difficult since no tools are available to estimate the risk of BD. In this study, we aimed to develop and validate a model of oxidative stress injury for predicting BD. Data were collected from 1252 BD and 1359 MDD patients, including 64 MDD patients identified as converting to BD from 2009 through 2018.

Screening of the college students at clinical high risk for psychosis in China: a multicenter epidemiological study.

Background: To investigate a 3-stage screening procedure and explore the clinical features of subjects at Clinical High Risk (CHR) for psychosis in a representative sample of Chinese college students.

Methods: An epidemiological survey of the prevalence of the CHR syndrome in Chinese college students that was selected by stratified random sampling from Shanghai, Nanjing and Nanchang cities was done following a 3-stage procedure. Participants were initially screened with the Prodromal Questionnaire-brief version (PQ-B), and whose distress score of PQ-B exceeded 24 would be invited to a telephone assessment using the subscale for positive symptoms of the Scale of Prodromal Symptoms (SOPS)/Structured Interview for Prodromal Syndromes (SIPS).

Brain regional homogeneity and function connectivity in attenuated psychosis syndrome -based on a resting state fMRI study.

Background: By combining regional homogeneity (ReHo) and functional connectivity (FC) analyses, this study aimed to explore brain functional alterations in Attenuated Psychosis Syndrome (APS), which could provide complementary information for the neurophysiological indicators for schizophrenia (SZ) associated brain dysfunction.

Methods: Twenty-one APS subjects and twenty healthy controls were enrolled in the data acquisition of demographics and clinical characteristics as well as structural and resting-state functional magnetic resonance imaging (rs-fMRI). ReHo analysis was conducted to determine the peak coordinate of the abnormal regional brain activity.
