Insulin resistance links dysbiosis of gut microbiota with cognitive impairment in first-episode drug-naïve schizophrenia.

This study aimed to explore the relationship among gut microbiota imbalance, the homeostasis model of assessment of insulin resistance (HOMA-IR) and cognitive impairments in patients with schizophrenia (SCZ). We conducted a case-control study involving 189 first-episode, drug-naïve SCZ patients and 115 healthy controls (HCs). Main methods adopted included metagenomics analysis, glucose metabolism assessment, and cognitive function evaluation using the MATRICS Consensus Cognitive Battery (MCCB).

The entorhinal cortex and cognitive impairment in schizophrenia: A comprehensive review.

Schizophrenia, a severe mental illness characterized by cognitive impairment and olfactory dysfunction, remains an enigma with its pathological mechanism yet to be fully elucidated. The entorhinal cortex, a pivotal structure involved in numerous neural loop circuits related to olfaction, cognition, and emotion, has garnered significant attention due to its structural and functional abnormalities, which have been implicated in the pathogenesis of schizophrenia. This review focuses on the abnormal structural and functional changes in the entorhinal cortex in schizophrenia patients, as evidenced by neuroimaging, cellular biology, and genetic studies.

Dysfunctional attitudes, social support, negative life events, and depressive symptoms in Chinese adolescents: A moderated mediation model.

Background: Depression is a prevalent psychological issue in adolescents that is significantly related to negative life events (NLEs) and dysfunctional attitudes. High levels of social support can significantly buffer NLEs' effect on depression. Currently, there is limited research on how social support moderates the relationship between NLEs, dysfunctional attitudes, and depression in adolescents in China.

Subjective time dilation in abstinent patients with alcohol use disorder.

Introduction: Patients with alcohol use disorder (AUD) may have distortions in time perception. This study investigated subjective time dilation (the tendency to perceive a time interval longer than it is) and its association with craving and impulsivity in AUD.

Method: Thirty abstinent male inpatients with AUD (age 29-60 years) and thirty sex-, age-, and education-matched healthy controls completed a temporal generalization task, which assessed the preference (point of subjective equality, PSE) and sensitivity of time perception in the second range.

A red turn-on fluorescent probe reveals elevated HO in cell anesthesia.

Cognitive dysfunction has become an important central nervous system (CNS)-related adverse reaction of intravenous anesthetics. Therefore, to further understand the role of HO, a potential marker of cognitive dysfunction, we constructed a fluorescent probe (LJ-1), which could specifically enable real-time detection of HO in cells during anesthesia.

The different impacts of functional network centrality and connectivity on the complexity of brain signals in healthy control and first-episode drug-naïve patients with major depressive disorder.

In recent years, brain signal complexity has gained attention as an indicator of brain well-being and a predictor of disease and dysfunction. Brain entropy quantifies this complexity. Assessment of functional network centrality and connectivity reveals that information communication induces neural signal oscillations in certain brain regions.

Patient-rated scales improve the classification accuracy for patients with depression and anxiety disorder: a linear discriminant analysis.

Background: The current study aimed to investigate the performances of clinical scales rated by clinicians and patients as well as cognitive function tests in distinguishing patients with affective and anxiety disorders from healthy controls (HCs).

Methods: We recruited a total of 122 subjects, comprising 24 patients with bipolar disorder (BD), 34 patients with major depressive disorder (MDD), 29 patients with anxiety disorder (AD), and 35 matched HCs. Three clinician-rated scales and five patient-rated scales were used to quantify clinical symptoms, while four cognitive tests were employed to measure cognitive functions in all subjects.

Advances in research on medications for the treatment of alcohol use disorders: A review.

Alcohol use disorder (AUD) has become a global public health challenge, with the social and economic costs of alcohol abuse escalating, drawing widespread attention from healthcare professionals and the public worldwide. Particularly in recent years, the COVID-19 pandemic and associated lockdown measures have led to a significant increase in global alcohol consumption, further exacerbating the risk of AUD and sparking in-depth discussions on its prevention and treatment methods. Given that the current mainstay of AUD treatment relies on pharmacotherapy, the aim of this article is to review the progress of existing drug research for the treatment of AUD, and at the same time to focus on drug classes that have not yet been applied to the clinic, but have been shown in recent studies to be potentially exploitable for the treatment of AUD, in order to provide new ideas and directions for future drug research and development efforts.

Associations Between Psychological Stress and the Risk of First Onset of Major Depression Disorder: Results from a Longitudinal Study in 6,985 Chinese First-Year Students.

Background: Youth and young adults have a high prevalence of major depressive disorder (MDD). Limited longitudinal research has explored the relationship between different dimensions of psychological stress and MDD. This study aimed to estimate the effect of psychological stress on the risk of first onset MDD in a sample of Chinese freshmen.

Dysphagia in schizophrenia: pathological mechanisms and treatment recommendations.

Schizophrenia is a chronic, severe, and disabling mental disorder that significantly impacts individuals' lives. Long-term treatment with antipsychotic drugs, coupled with the complications of the disease itself, increases the risk of dysphagia in patients. These disorders further heighten the likelihood of choking and asphyxia death among this population.

Shared and Distinct White Matter Alterations in Major Depression and Bipolar Disorder: A Systematic Review and Meta-Analysis.

Background: Identifying white matter (WM) microstructural similarities and differences between major depressive disorder (MDD) and bipolar disorder (BD) is an important way to understand the potential neuropathological mechanism in emotional disorders. Numerous diffusion tensor imaging (DTI) studies over recent decades have confirmed the presence of WM anomalies in these two affective disorders, but the results were inconsistent. This study aimed to determine the statistical consistency of DTI findings for BD and MDD by using the coordinate-based meta-analysis (CBMA) approach.

Dynamic brain entropy predicts risky decision-making across transdiagnostic dimensions of psychopathology.

Objectives: Maladaptive risky decision-making is a common pathological behavior among patients with various psychiatric disorders. Brain entropy, which measures the complexity of brain time series signals, provides a novel approach to assessing brain health. Despite its potential, the dynamics of brain entropy have seldom been explored.

Exploring the mediating role of the ventral attention network and somatosensory motor network in the association between childhood trauma and depressive symptoms in major depressive disorders.

Background: Childhood trauma is closely tied to adult depression, but the neurobiological mechanisms remain unclear. Previous studies suggested associations between depression and large-scale brain networks such as the Ventral Attention Network (VAN) and Somatosensory Motor Network (SMN). This study hypothesized that functional connectivity (FC) within and between these networks mediates the link between childhood trauma and adult depression.

Epidemiological study on seroprevalence of syphilis in patients with mental diseases.

Introduction: The objective of this study was to investigate the seroprevalence of syphilis and its possible influencing factors in patients with mental illness.

Methodology: A total of 24,414 patients with mental illness from 2019 to 2021 were included. Serum syphilis antibody test results and available demographic data were collected.

Randomized, double-blind, placebo-controlled trial of aripiprazole oral solution in children and adolescents with Tourette's disorder.

Background: Aripiprazole is the most frequently recommended antipsychotic for the treatment of tics in children and adolescents with Tourette's disorder (TD). However, to date, a randomized controlled trial for aripiprazole oral solution has not been conducted despite being widely preferred by children. Therefore, we examined whether aripiprazole oral solution is effective for treating tics.

Neural dysfunction underlying working memory processing at different stages of the illness course in schizophrenia: a comparative meta-analysis.

Schizophrenia, as a chronic and persistent disorder, exhibits working memory deficits across various stages of the disorder, yet the neural mechanisms underlying these deficits remain elusive with inconsistent neuroimaging findings. We aimed to compare the brain functional changes of working memory in patients at different stages: clinical high risk, first-episode psychosis, and long-term schizophrenia, using meta-analyses of functional magnetic resonance imaging studies. Following a systematic literature search, 56 whole-brain task-based functional magnetic resonance imaging studies (15 for clinical high risk, 16 for first-episode psychosis, and 25 for long-term schizophrenia) were included.

The impact of physical therapy on dysphagia in neurological diseases: a review.

A neurogenic dysphagia is dysphagia caused by problems with the central and peripheral nervous systems, is particularly prevalent in conditions such as Parkinson's disease and stroke. It significantly impacts the quality of life for affected individuals and causes additional burdens, such as malnutrition, aspiration pneumonia, asphyxia, or even death from choking due to improper eating. Physical therapy offers a non-invasive treatment with high efficacy and low cost.
