The current study examined the effects of applying relaxation breathing training (RBT) as a means to reduce music performance anxiety (MPA) in young, talented musicians. A group of 59 young musicians from 3rd to 6th grade participated in this study, and all of them started RBT twice a week for 2 months prior to the examination. Four tests--2 mos, 1 mos, half an hour and 5 min before the examination--were conducted to examine the level of MPA after the application of RBT. Results show that the degree of MPA 5 min before the trial was lower than the degree of performance anxiety half an hour before the jury (t = -3.683, p < 0.01), which indicated that the RBT was associated with a decrease in MPA. Although a series of RBT exercises was applied, results indicated that when approaching the date of examination, the degree of performance anxiety still increased and reached its maximum half an hour before the jury. The recommendation for future studies is to combine the application of RBT with other methods to expand its effect in reducing MPA.

The T22 protocol is an animal model of forced internal desynchronization, in which rats are exposed to an 11:11 light-dark (LD) cycle. This non-invasive protocol induces the dissociation of circadian rhythms in adult rats, making it possible to study the effects of circadian disruption on physiological and behavioral processes such as learning, memory, and emotional responses. However, the effects of circadian dissociation during other developmental stages, such as adolescence, remain unexplored.

A physiological signal-based Human-Computer Interaction (HCI) system provides a communication link between human emotional states and external devices. Accurately classifying these signals is vital for effective interaction, which requires extracting and selecting the most discriminative features to differentiate between various emotional states. This paper introduces the SMOTETomek-Correlated Interactive Reinforcement Learning (ST-CIRL) framework for anxiety classification, which leverages meta-descriptive statistics to enhance the state representation in the reinforcement learning process.

Background: Cold-water immersion (CWI) has gained popularity as a health and wellbeing intervention among the general population.
Objective: This systematic review and meta-analysis aimed to evaluate the psychological, cognitive, and physiological effects of CWI in healthy adults.
Methods: Electronic databases were searched for randomized trials involving healthy adults aged ≥ 18 years undergoing acute or long-term CWI exposure via cold shower, ice bath, or plunge with water temperature ≤15°C for at least 30 seconds.
The COVID-19 pandemic instigated changes in almost all aspects of youth's life. While numerous studies have been implemented to understand how these changes are related to youth's development, few concerned large representative samples. This study introduces the methodology and initial results of the Quebec (Canada) Resilience Project (QRP), a representative longitudinal study.

Hyperparathyroidism is a rare entity in pediatrics. It is defined as the increased production of parathyroid hormone. It may be due to a primary defect of the parathyroid glands (primary hyperparathyroidism) or to a compensatory parathyroid hormone production to correct hypocalcemia states of various origins (secondary hyperparathyroidism).
