Summary: Early adversity can impact cortisol secretion patterns, with individuals first exposed between ages 3 and 7 showing differences in cortisol awakening response and reactivity compared to those exposed at other ages. The findings support the Life Cycle Model of Stress and emphasize the importance of considering the age of exposure to early adversity in assessing cortisol secretion patterns.

Summary: This study found that prenatal MA exposure and early childhood adversity were associated with increased DNA methylation of HSD11B2. Even after adjusting for covariates, the significant effects of early childhood adversity and prenatal MA exposure on DNA methylation remained.

Summary: This study examines the association between adverse childhood experiences and reactivity to interpersonal stressors reminiscent of early adverse experiences. The results partially support the hypothesis that participants with greater early adversity may be more reactive to these stressors.

Summary: This study reported the youngest case of postinfectious ADEM due to SARS-CoV-2 in a toddler, with full neurologic recovery after treatment. Early recognition of autoimmune and inflammatory complications is crucial for aggressive immunomodulatory treatment and improved outcomes in SARS-CoV-2 patients.

Summary: This article reports the intact survival of extremely preterm twins born at 22 2/7 weeks without significant morbidity. It highlights the importance of perinatal and neonatal management optimization to improve survival rates and clinical outcomes of periviable birth, as well as the need to consider the individuality of each case and the parents' wishes in management decisions.

Summary: A study found that exposure to phenols and phthalates (PAEs) can affect the body size of twins. The researchers collected urine samples from pregnant twins and detected 8 PAE metabolites and 7 phenols using liquid chromatography-tandem mass spectrometry. The results showed that these chemicals were positively associated with weight differences in twins throughout the entire trimester, and increased exposure to these chemicals was linked to larger weight and height differences in twins.

Summary: The study found that higher levels of personal mastery and perceived constraints are associated with stress reactivity, but this association varies among different racial and age groups. Older adults seem to be buffered against the link between facets of control and cortisol stress reactivity.

Summary: This study examines the impact of growing up in urban environments on infants' physiological and cognitive development. Infants from high-density urban settings showed increased physiological stress at home, but also demonstrated better recognition memory and increased neural engagement with stimuli in the lab.

Summary: The study suggests that connectivity measured through EEG during ASL at 3 months may predict the later onset of autism spectrum disorder symptoms at 18 months. Additionally, the alpha coherence at 3 months correlates positively with word production at 18 months, indicating that early alterations in connectivity may serve as markers for predicting neurodevelopmental outcomes in infants.

Summary: The study found that there were larger differences in maximum load among families in mature wood compared to juvenile wood of Larix kaempferi trees, indicating the potential for improving mature wood with higher resistance to rupture by selecting specific mating parents. The study highlights the importance of wood properties and bending properties in tree breeding programs for construction lumber.

Summary: The Trier Social Stress Test (TSST) has been shown to reliably induce physiological stress responses in the HPA and SAM axis. Repeated exposure to the TSST over a 4-month interval reinstated the physiological stress response, suggesting reliability in longitudinal studies. Subjective stress responses showed minor test-retest effects.

There is still limited data on the natural history of COVID-19 in pediatric population, highlighting the importance of describing rare manifestations in children's acute infection.

Summary: Adolescent pain is common and continues into adulthood, and defining its construct through empirical research can help early detection of persistent pain trajectories. This study found that back pain is consistently associated with frequent adolescent pain trajectory, and it has good sensitivity in predicting the trajectory.

Summary: This study investigated prenatal and early postnatal risk factors associated with the development of disruptive behaviors. The findings showed that pure forms of disruptive behaviors have specific etiologies, while co-occurrent disruptive behaviors share common risk factors. Risk factors such as male sex, a higher number of siblings, maternal symptoms of depression and conduct problems, young motherhood, lack of positive parenting, family dysfunction, and lower socioeconomic status were found to affect the development of disruptive behaviors.

Summary: This study aimed to understand how early oral language contributes to later writing skills and to explore the extent to which genetic and environmental factors explain these potential associations. The results showed that preschool language skills were modestly associated with high school writing and that school age language fully mediated this association. Additionally, genetic factors explained a significant portion of the associations between preschool language and school age language, as well as between school age language and high school writing.

Summary: Prospective research is needed to better understand the changes in substance use among emerging adults during the COVID-19 pandemic. The study found that changes in alcohol and cannabis use varied according to preexisting substance use, COVID-19-related factors, and preexisting factors. While some young individuals with preexisting vulnerabilities showed stable or decreased substance use, those who experienced employment loss, loneliness, and financial concerns during COVID-19 increased their substance use. This highlights the importance of providing support for vulnerable populations during the pandemic.

Summary: This study examined the role of genetic and environmental factors in explaining different trajectories of adolescents' depressive symptoms, as well as the correlation between genetic factors and peer victimization. The results showed that genetic factors explained about half of the probability of following a low or increasing trajectory, while nonshared environmental factors explained the remaining variance. Moreover, frequent peer victimization increased the influence of nonshared environmental factors.

Summary: This study explores the patterns of relative academic achievement of children in the classroom from grade 1 to grade 6 and their associations with child, parental, and socio-familial characteristics. The findings indicate that low parental education and family income, male sex, and poor parental behaviors and attitudes towards the child are associated with a lower trajectory of relative academic achievement.

Summary: Sleep duration during early childhood is associated with long-term academic achievement. Children who slept less than 8 hours per night at 2.5 years had higher odds of having below average grades in various subjects compared to those who slept sufficiently. Sufficient sleep in early childhood is important for academic success.

Summary: A study of 36,516 parents from six international cohorts reveals associations between parental genetics and parental investments in offspring, from behaviors during pregnancy to wealth inheritance in adulthood. The effects of parental genetics on behaviors tend to be small at any given time point, but accumulate over development. This suggests that parents pass on advantages to their children through genetic associations with investments across various stages of development.

Summary: This study, using a longitudinal design, found that early hyperactivity, overeating, cognitive inflexibility, and working memory may precede the onset of eating-disorder symptoms in adolescence. Screening children's behavior and cognition early on may help identify those most at risk for eating disorders and guide preventive interventions.

Summary: The study found that preference for solitude, instead of social wariness, predicts peer difficulties. Preference for solitude was closely related to peer rejection starting at age 6 and gradually became associated with peer victimization over time. These results highlight the importance of distinguishing different dimensions of social withdrawal.
