Cognitive impairments in first-episode psychosis patients with attenuated niacin response.

Background: Psychosis is a complex brain disorder with diverse biological subtypes influenced by various pathogenic mechanisms, which can affect treatment efficacy. The ANR(Attenuated Niacin Response) subtype is characterized by pronounced negative symptoms and functional impairments, suggesting a distinct clinical profile. However, research on the cognitive characteristics associated with the ANR subtype in drug-naïve first-episode psychosis(FEP) patients remains limited.

Identifying neurobiological heterogeneity in clinical high-risk psychosis: a data-driven biotyping approach using resting-state functional connectivity.

To explore the neurobiological heterogeneity within the Clinical High-Risk (CHR) for psychosis population, this study aimed to identify and characterize distinct neurobiological biotypes within CHR using features from resting-state functional networks. A total of 239 participants from the Shanghai At Risk for Psychosis (SHARP) program were enrolled, consisting of 151 CHR individuals and 88 matched healthy controls (HCs). Functional connectivity (FC) features that were correlated with symptom severity were subjected to the single-cell interpretation through multikernel learning (SIMLR) algorithm in order to identify latent homogeneous subgroups.

Structural and functional abnormalities across clinical stages of psychosis: A multimodal neuroimaging investigation.

Background: Structural and functional neurobiological abnormalities have been observed in schizophrenia. Previous studies have concentrated on specific illness stages, obscuring relationships between functional/structural changes and disorder progression. The present study aimed to quantify structural and functional abnormalities across different clinical stages using functional near-infrared spectroscopy (fNIRS) and structural magnetic resonance imaging (sMRI).

Transplantation of gut microbiota derived from patients with schizophrenia induces schizophrenia-like behaviors and dysregulated brain transcript response in mice.

Schizophrenia (SCZ), as a neurodevelopmental disorder and devastating disease, affects approximately 1% of the world population. Although numerous studies have attempted to elucidate the causes of SCZ occurrence, it is not clearly understood. Recently, the emerging roles of the gut microbiota in a range of brain disorders, including SCZ, have attracted much attention.

Inflammation and comorbidities of chronic obstructive pulmonary disease: The cytokines put on a mask!

Objective: Chronic obstructive pulmonary disease (COPD) is a well-known complex multicomponent disease characterized by systemic inflammation that frequently coexists with other conditions. We investigated the relationship between some inflammatory markers and complications in COPD patients to explore the possible roles of inflammation in these comorbidities.

Methods: This study used cross-sectional and case-control methods.

A case of antipsychotic-induced psychomotor seizure.

A seizure is one of the most uncommon severe adverse side effects of antipsychotics. Clinical recognition rates for it are low, especially for psychomotor seizures. The authors present a case of psychomotor seizure caused by amisulpride to treat schizophrenia.

Metformin in the Treatment of Amisulpride-Induced Hyperprolactinemia: A Clinical Trial.

Objective: To evaluate the efficacy and safety of metformin in the treatment of amisulpride-induced hyperprolactinemia.

Methods: A total of 86 schizophrenic patients who developed hyperprolactinemia after taking amisulpride were screened and randomly assigned to the metformin group (42 patients) and placebo group (44 patients) and followed up for eight weeks. The patients' serum prolactin levels, blood glucose and lipids were measured at the baseline and the end of the intervention.

How psychiatrists coordinate treatment for COVID-19: a retrospective study and experience from China.

Background: Patients with COVID-19 are at high risk of developing mental health problems; however, the prevalence and management of mental disorders and how psychiatrists coordinate the treatment are unclear.

Aims: We aimed to investigate the mental health problems of patients infected with COVID-19 and to identify the role of psychiatrists in the clinical treatment team during the pandemic. We also share the experience of psychiatric consultations of patients with COVID-19 in Shanghai, China.

Frequency of Self-reported Psychotic Symptoms among 2542 Outpatients at Their First Visit for Mental Health Services.

: Psychotic symptoms are prevalent in both clinical settings and the general population. The distribution of psychotic symptoms across patients with different types of psychotic and non-psychotic mental disorders is helpful for understanding symptom specificity. This study aimed to explore the distribution differences of psychotic symptoms in an outpatient population in terms of frequency, age, gender, and psychotic and non-psychotic disorders.

Multiple Factor Analysis of Depression and/or Anxiety in Patients with Acute Exacerbation Chronic Obstructive Pulmonary Disease.

Objective: To reveal the risk factors, the symptom distribution characteristics, the clinical values of white blood cell counts (WBC counts), red blood cell distribution width (RDW), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and monocyte-to-lymphocyte ratio (MLR) in hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) combined with depression and/or anxiety.

Methods: The study included prospective cross-sectional and case-control studies, and was executed in the Affiliated Hospital of Zunyi Medical University, Guizhou, China. Previously diagnosed chronic obstructive pulmonary disease (COPD) patients who admitted to the hospital with AECOPD, patients with depression and/or anxiety, and healthy people were enrolled in the study.

Association of Folate Level in Blood with the Risk of Schizophrenia.

Aim And Objective: The aim of this study was to evaluate the association between folate level and the risk of schizophrenia and to identify possible biomarker for schizophrenia.

Materials And Methods: Data about folate were extracted from 16 high quality studies. The association of folate level in blood and schizophrenia was evaluated using standardized mean difference (SMD) and 95% confidence interval (CI).
