Visual and auditory attention defects in children with intermittent exotropia.

Background: Previous studies have shown that children with intermittent exotropia (IXT) have a higher rate of psychiatric abnormalities as they grow up, such as attention deficit. This study explored visual and hearing attention among children with IXT, and evaluated its association with clinical characteristics and cognitive development.

Methods: Forty-nine children with a diagnosis of IXT and 29 children with traditional development were recruited.

Association of adiposity with risk of obstructive sleep apnea: a population-based study.

Background: Obesity is a crucial risk factor for obstructive sleep apnea (OSA), but the association between adiposity deposition and OSA risk has not reached a consistent conclusion. This study sought to reveal the association of multiple adiposity indicators with OSA risk.

Methods: This cross-sectional study included 9,733 participants aged 35-74 years, recruited from an ongoing population-based cohort.

Evidence for Dopamine Abnormalities Following Acute Methamphetamine Exposure Assessed by Neuromelanin-Sensitive Magnetic Resonance Imaging.

Background: Neuromelanin-sensitive magnetic resonance imaging (NM-MRI) is a newly developed MRI technique that provides a non-invasive way to indirectly measure of dopamine (DA) function. This study aimed to determine NM concentrations in brain regions following acute methamphetamine (MA) administration using NM-MRI and to explore whether NM-MRI can be used as a biomarker of DA function in non-neurodegenerative diseases.

Methods: Baseline NM-MRI, T1-weighted and T2-weighted images were acquired from 27 rats before drug/placebo injection.

Survivors of COVID-19 exhibit altered amplitudes of low frequency fluctuation in the brain: a resting-state functional magnetic resonance imaging study at 1-year follow-up.

Although some short-term follow-up studies have found that individuals recovering from coronavirus disease 2019 (COVID-19) exhibit anxiety, depression, and altered brain microstructure, their long-term physical problems, neuropsychiatric sequelae, and changes in brain function remain unknown. This observational cohort study collected 1-year follow-up data from 22 patients who had been hospitalized with COVID-19 (8 males and 11 females, aged 54.2 ± 8.

Eye-movement Patterns of Chinese Children with Developmental Dyslexia during the Stroop Test.

Objective: To compare the eye-movement patterns of Chinese children with developmental dyslexia (DD children) with those of non-dyslexic children as they perform the Stroop Color and Word Test (SCWT), and to explore the relationship between their eye-movement patterns and interference effect.

Methods: An EyeLink II was used to record the eye-movement parameters of 32 DD children and 37 non-dyslexic children as they performed the SCWT. The independent samples t-test and repeated measures were used to analyze behavioral and eye-movement parameters.

Dental caries is negatively correlated with body mass index among 7-9 years old children in Guangzhou, China.

Background: Evidence linking caries in primary dentition and children's anthropometric measures is contradictory. We aimed to evaluate the prevalence of primary dental caries and its relationship with body mass index (BMI) among 7-9 years old school children in urban Guangzhou, China.

Methods: This cross-sectional study enrolled 32,461 pupils (14,778 girls and 17,683 boys) aged 7-9 years from 65 elementary schools in Guangzhou.

Violence-related behaviors among adolescents and its association with cognitive emotion regulation strategies.

Background: Adolescent violence is now regarded as a major public health concern. Despite growing interest in psychographic risk factors for violent behavior, few studies have explored the role of strategies to regulate cognitive emotion in adolescents. This study aimed to investigate the prevalence of adolescent violence behaviors and to identify the relationship between specific strategies to regulate cognitive emotion and forms of violent behavior.

Risk factors for predicting postoperative complications after open infrarenal abdominal aortic aneurysm repair: results from a single vascular center in China.

Study Objective: To identify the risk factors of, and develop a prediction model for, postoperative complications of patients undergoing infrarenal abdominal aortic aneurysm (IAAA) repair.

Design: Retrospective analysis.

Setting: Vascular surgery center of a university hospital.

The Chinese version of the Obsessive-Compulsive Inventory-Revised scale: replication and extension to non-clinical and clinical individuals with OCD symptoms.

Background: The Obsessive-Compulsive Inventory-Revised (OCI-R) was designed to evaluate the severity of obsessive-compulsive symptoms in both clinical and non-clinical samples. The aim of the study was to evaluate the psychometric properties of a Chinese version of this scale.

Methods: The Chinese version of the OCI-R was administered to both a non-clinical sample (209 undergraduate students) and a clinical sample (56 obsessive-compulsive disorder (OCD) patients).

Regional cerebral blood flow in children with autism spectrum disorders: a quantitative ⁹⁹mTc-ECD brain SPECT study with statistical parametric mapping evaluation.

Background: Autism spectrum disorders (ASD), which include autism, asperger syndrome (AS) and pervasive developmental disorder-not otherwise specified (PDD-NOS), are devastating neurodevelopmental disorders of childhood resulting in deficits in social interaction, repetitive patterns of behaviors, and restricted interests and activities. Single photon emission computed tomography (SPECT) is a common technique used to measure regional cerebral blood flow (rCBF). Several studies have measured rCBF in children with ASD using SPECT, however, findings are discordant.
