Development and Validation of a Self-Administered Screening Test for Betel Quid Use Disorders in Betel Quid Chewers in Hunan, China.

Introduction: Processed betel quid product chewing is a public health problem in areca non-plant areas in China. However, there is no valid instrument to screen for betel quid use disorder (BQUD) in mainland China. We developed a self-administered screening test for betel quid use disorders (SST-BQUD) and tested its reliability and validity in a sample of betel quid chewers (BQCers) in Hunan, China.

Obesity-Associated Anxiety Is Prevalent among College Students and Alleviated by Calorie Restriction.

Anxiety is a common disorder among college students, especially those with obesity. Obesity contributes to metabolic disorders and disturbs the neural functions, further leading to anxiety. In this cross-sectional study, we aimed to determine the association between obesity and anxiety among college students and identified the potential factors for obesity-associated anxiety.

Classification of schizophrenia using general linear model and support vector machine via fNIRS.

Schizophrenia is a type of serious mental illness. In clinical practice, it is still a challenging problem to identify schizophrenia-related brain patterns due to the lack of objective physiological data support and a unified data analysis method, physicians can only use the subjective experience to distinguish schizophrenia patients and healthy people, which may easily lead to misdiagnosis. In this study, we designed an optimized data-preprocessing method accompanied with techniques of general linear model feature extraction, independent sample t-test feature selection and support vector machine to identify a set of robust fNIRS pattern features as a biomarker to discriminate schizophrenia patients and healthy people.

The associations between anxiety/depression and plasma chromogranin A among healthy workers: Results from EHOP study.

Objectives: Chromogranin A (CgA) is regarded as an indicator of sympathetic tone and adrenomedullary system activity. Catestatin is one of CgA-derived fragments through proteolytic processing. Many studies have confirmed the correlation between anxiety/depression and the salivary CgA level.

Investigation on entraining and enhancing human circadian rhythm in closed environments using daylight-like LED mixed lighting.

Humans can undergo circadian disruption and misalignment when living in closed environments without sufficient daylight. Therefore, it is of great significance to investigate the effects of artificial light on the circadian rhythm. In this work, the red, green, blue, warm white, and cool white (RGBWW) five-channel light-emitting diodes (LEDs) were fabricated as the only light sources in the closed environment.

Implementing machine learning in bipolar diagnosis in China.

Bipolar disorder (BPD) is often confused with major depression, and current diagnostic questionnaires are subjective and time intensive. The aim of this study was to develop a new Bipolar Diagnosis Checklist in Chinese (BDCC) by using machine learning to shorten the Affective Disorder Evaluation scale (ADE) based on an analysis of registered Chinese multisite cohort data. In order to evaluate the importance of each item of the ADE, a case-control study of 360 bipolar disorder (BPD) patients, 255 major depressive disorder (MDD) patients and 228 healthy (no psychiatric diagnosis) controls (HCs) was conducted, spanning 9 Chinese health facilities participating in the Comprehensive Assessment and Follow-up Descriptive Study on Bipolar Disorder (CAFÉ-BD).

Depressive symptoms in Chinese assembly-line migrant workers: A case study in the shoe-making industry.

Introduction: Assembly-line migrant workers (AMWs), as a major workforce in China, may be at particularly high risk of depression due to their relative low social economic status and particular job characteristics. However, little is known about the frequency and characteristics of depression among Chinese AMWs. This study investigated the prevalence and correlates of depressive symptoms in Chinese AMWs.

Automatic schizophrenic discrimination on fNIRS by using complex brain network analysis and SVM.

Background: Schizophrenia is a kind of serious mental illness. Due to the lack of an objective physiological data supporting and a unified data analysis method, doctors can only rely on the subjective experience of the data to distinguish normal people and patients, which easily lead to misdiagnosis. In recent years, functional Near-Infrared Spectroscopy (fNIRS) has been widely used in clinical diagnosis, it can get the hemoglobin concentration through the variation of optical intensity.

Clinical efficacy, onset time and safety of bright light therapy in acute bipolar depression as an adjunctive therapy: A randomized controlled trial.

Background: Bright light therapy (BLT) is an effective treatment for seasonal affective disorder and non- seasonal depression. The efficacy of BLT in treating patients with bipolar disorder is still unknown.

Aims: The aim of this study is to examine the efficacy, onset time and clinical safety of BLT in treating patients with acute bipolar depression as an adjunctive therapy (trial registration at ClinicalTrials.

[Reliability and validity of Professional Quality of Life Scale among government staff in earthquake - stricken areas in China].

Objective: To evaluate the reliability and validity of Professional Quality of Life Scale (ProQOL-30, 4th version, 30 items) among government staff in the Wenchuan earthquake-stricken areas

Methods: A total of 1,175 members of government staff in the Wenchuan earthquake-stricken areas were selected by convenience sampling and required to complete the ProQOL and Self-Reporting Questionnair (SRQ). The reliability and validity of the scale was evaluated by correlation analysis, t-test, and confirmatory factor analysis.
