Comparison of Negative Symptom Network Structures Between Patients With Early and Chronic Schizophrenia: A Network and Exploratory Graph Analysis.

Background And Hypothesis: Despite the clinical relevance of negative symptoms in schizophrenia, our understanding of negative symptoms remains limited. Although various courses and stages of schizophrenia have been identified, variations in the negative symptom networks between distinct stages of schizophrenia remain unexplored.

Study Design: We examined 405 patients with early schizophrenia (ES) and 330 patients with chronic schizophrenia (CS) using the Scale for the Assessment of Negative Symptoms.

Using infographics in disseminating healthy lifestyle information on social media is likely to increase uptake and sharing.

Background: Infographics facilitate rapid information dissemination with enriched eye-catching content on social media, but it is unclear what factors affect the adoption of information presented in this way.

Objectives: We tested whether the Information Acceptance Model applies to infographics on healthy lifestyle and fitness topics.

Methods: Two hundred and four university students were invited to participate in an online survey on their acceptance after reading some healthy lifestyle and fitness topics infographics shared on social media.

A systematic review of neuroimaging studies of clozapine-resistant schizophrenia.

This systematic review aimed to review neuroimaging studies comparing clozapine-resistant schizophrenia patients with clozapine-responding patients, and with first-line antipsychotic responding (FLR) patients. A total of 19 studies including 6 longitudinal studies were identified. Imaging techniques comprised computerized tomography (CT, n = 3), structural magnetic resonance imaging (MRI, n = 7), magnetic resonance spectroscopy (MRS, n = 5), functional MRI (n = 1), single-photon emission computerized tomography (SPECT, n = 3) and diffusion tensor imaging (DTI, n = 1).
