Article Abstract

Background: Based on the gene-environment interaction paradigm, this study explored the effect of peer relationships on adolescent loneliness and the role of psychological resilience and the oxytocin receptor gene (OXTR).

Methods: A survey was conducted in a sample of 619 adolescents, and their oral cells were collected for DNA extraction and genotyping.

Results: The results showed that (1) both peer relationships and psychological resilience significantly affected adolescent loneliness; (2) psychological resilience partially mediated the relationship between peer relationships and loneliness in adolescents; (3) OXTR gene rs53576 polymorphism moderated both the first and second half of the indirect pathway of the mediation model. Specifically, carriers of the rs53576 polymorphism A/A genotype showed a significantly enhanced effect of peer relationships on adolescent psychological resilience, while carriers of the rs53576 polymorphism G/G genotype showed a significantly enhanced effect of psychological resilience on adolescent loneliness.

Conclusion: These findings helped elucidate the developmental mechanisms of adolescent loneliness in terms of peer relationships, psychological resilience, and OXTR gene polymorphisms.

To enhance performance, increase resilience and prevent injuries, training and testing (T&T) are the most important strategies for preparing athletes for the demands of their sport. However, for competitive snow sports such as alpine skiing, freestyle skiing and snowboarding, there is little evidence and a lack of international harmonisation of current best practices. This consensus statement, commissioned by the International Ski and Snowboard Federation (FIS), aims to provide recommendations for the physical and psychological T&T of competitive alpine and freestyle skiers and snowboarders within National Ski and Snowboard Associations.

Objective: To assess the clinical application and therapeutic efficacy of the Traditional Chinese Medical (TCM) management model among elderly individuals in a sub-health state, and to evaluate its impact on patients' quality of life (QoL).

Methods: A retrospective cohort study was conducted, analyzing clinical data from sub-health elderly patients who received care at a designated medical institution between January 2021 and December 2023. A total of 180 patients meeting the predefined inclusion criteria were recruited and stratified into two arms based on the intervention administered.

This case report describes the implementation of Family-Centered Care (FCC) and developmental occupational therapy (OT) for an extremely preterm infant born at 22 weeks and one day of gestation, weighing 448 g. The infant experienced multiple complications, including necrotizing enterocolitis, sepsis, intraventricular hemorrhage, and respiratory distress, requiring prolonged intensive care. Due to physiological fragility and immature neurobehavior, a structured rehabilitation approach was introduced, integrating OT and caregiver participation based on FCC principles.
