We aimed to investigate whether pituitary volume, an index of hypothalamic–pituitary–adrenal (HPA) axis function, represents a vulnerability factor for the emergence of internalizing and externalizing symptoms during adolescence using a prospective, longitudinal design. Methods:  One hundred and fifty-five adolescents completed 3T structural magnetic resonance imaging (MRI), symptom rating scales and a diagnostic interview during early adolescence (M age 12.6 years, SD .5 years); symptom rating scales were re-administered approximately three years later (M age 15.2 years). The volume of the pituitary gland was estimated by manually delineating its structure on MR images. The degree to which pituitary volumes prospectively predicted change in internalizing and externalizing symptoms across the two time-points was assessed using hierarchal linear regression, after controlling for the influence of gender, age, pubertal stage and intracranial volume. Results:  Larger pituitary volumes prospectively predicted an increase in internalizing, but not externalizing, symptoms from early adolescence to mid-adolescence. Conclusions:  This study provides the first evidence that increased pituitary volume might represent a specific vulnerability marker for the development of internalizing symptoms during early to mid-adolescence.

The association between school holidays and trends in adolescent ambulance attendances for suicidal and non-suicidal self-injurious Behaviours / Ryan BALDWIN in Journal of Child Psychology and Psychiatry, 67-7 (July 2026)

This study utilised ambulance attendance data to explore whether protective effects of school holidays on suicidal and NSSI behaviours were present pre- and post-COVID-19 restrictions. Methods Using data from the National Ambulance Surveillance System, weekly ambulance attendances for suicidal and NSSI behaviours among adolescents (12?17) and young adults (18?25) in Victoria, Australia, were analysed. Trends in rates per 10,000 population pre- (2015?2019) and post-COVID-19 restrictions (2022?2023) were modelled using seasonal autoregressive integrated moving average with exogenous variables, stratified by age and gender. Results There were 20,635 suicidal and NSSI related ambulance attendances among adolescents and 36,510 among young adults. Pre-COVID-19 there was a significant decline in weekly rate of attendances per 10,000 population for adolescent females during the December/January (?0.35, p?
