Summary: The present study examined measurement invariance and psychometric properties of the SCAS-S in Chinese children. Results showed that the SCAS-S had strict measurement invariance across gender and a one-year time interval, and weak measurement invariance across informants. The self-report version of SCAS-S demonstrated good construct validity and the internal consistencies of its subscales were acceptable across different informants, gender, and time points. These findings suggest that the SCAS-S is a reliable tool to measure anxiety in Chinese children aged 9 to 13 years old.

Summary: The study validated the self-reported brief version of SCAS-C-8 in pre-adolescent Spanish children, with good fit to one-factor structure, adequate internal consistency, and evidence of test-retest reliability. There was a strong relationship between SCAS-C-8 and emotional problems, indicating convergent validity, as well as factorial gender invariance. In conclusion, SCAS-C-8 is suitable for pre-adolescent Spanish children, with its brevity and simplicity potentially aiding in early detection and bridging the gap between anxiety problems and psychological assistance-seeking.

Summary: Prenatal exposure to methylmercury can impact child development. This study compared two high-throughput methods for mercury speciation and found relatively good agreement between them. MeHg and IHg concentrations were determined in maternal and cord blood samples, highlighting the importance of analyzing different chemical forms for health effects.

Summary: This study found associations between prenatal MeHg exposure and cord blood DNA methylation levels, but limited evidence of these relationships in blood from 7 to 8 year-old children.

Summary: The study aimed to validate the Spanish version of the parent version of the SCAS-P and found that it demonstrated good internal consistency, excellent test-retest reliability, and supported convergent and divergent validity with other measures of anxiety, depression, and externalizing problems. The original factor structure of the SCAS-P, based on six correlated factors, was partially confirmed in an exclusively clinical sample.

Summary: The study found that shyness can manifest on behavioral, affective, and physiological levels, and identified four profiles of shyness in children. Membership in the higher reactive profile predicted higher parent-reported temperamental shyness across 2 years. These findings provide empirical support for the idea that shyness exists as both an emotional state and a distinct temperamental quality for some children.

Summary: Neurodevelopmental delays can have negative consequences on children's engagement and further development, and mercury, being highly toxic, may negatively influence neurodevelopment. However, based on current evidence, dietary mercury exposure during pregnancy is unlikely to be a risk factor for low neurodevelopmental functioning in early childhood.

Summary: This study examined the associations between prenatal exposure to metallic elements (mercury, selenium, and manganese) and the risk of allergic diseases in early childhood. The findings suggest that prenatal selenium exposure may be beneficial in reducing the risk of atopic dermatitis, food allergies, allergic rhinitis, and any allergic diseases, particularly with lower prenatal mercury exposure.

Summary: SSRI medication use during pregnancy has been a concern for safety. This study used female rats to investigate the effects of prenatal exposure to escitalopram. The results indicated that exposure during the first half of pregnancy resulted in better behavioral flexibility and lower anxiety-like behavior in adult offspring.

Summary: This study examined the associations between personality traits and unwanted behavioral traits in dogs. The results showed that dog personality traits resemble human personality traits and are associated with similar patterns of unwanted behaviors. This suggests that dogs may be a suitable animal model for studying human behavior and psychiatric disorders.

Summary: This study suggests that moderate-severe prenatal psychological distress in early pregnancy is associated with poor cognition in children at the age of 4, and daily intake of prenatal vitamins does not ameliorate this association. The findings highlight the importance of early screening and treatment for prenatal maternal mental illness.

Summary: This study used data from the National Survey of Children's Health 2016-2019 to examine the co-occurrence of autism and ADHD and the impact on anxiety and depression among adolescents age 12-17. The results showed that adolescents diagnosed with autism and/or ADHD had significantly higher rates of anxiety and depression compared to those without these diagnoses.

Summary: Neurodevelopmental disorders (NDDs) are complex conditions that arise in infancy and childhood and are influenced by a combination of genetic risk and environmental factors. Two-hit models, which incorporate both genetic and environmental alterations, are advantageous in uncovering underlying vulnerabilities. This review summarizes existing literature on the detrimental interactions between prenatal stress and genes associated with NDDs, with a focus on behavioral phenotyping approaches in mouse models. Identifying optimal stress protocols and critical developmental windows would enhance the utility of these gene x environment models of NDDs.

Summary: Epigenetic changes related to altered behavior and neuropsychiatric disorders are associated with maternal anxiety during pregnancy. The study found a link between maternal anxiety and children's DNA methylation levels, with sex differences and timing effects being highly important. However, DNA methylation was not supported as the underlying mechanism for the impact of maternal anxiety during pregnancy on offspring's behavioral measures.

Summary: This study demonstrates that methylphenidate can restore behavioral impairments and neuroplasticity in an ADHD mouse model induced by prenatal nicotine exposure. The restoration is achieved through changes in AMPAR subunit composition and distribution, as well as the maturation of dendritic spines.
