METHODS: We analyzed patients enrolled in the Vancouver Ruptured Aneurysm Database (VRAD) between December 2022 and September 2025. Demographic, clinical, radiographic, treatment and functional outcomes were compared between groups. Time from ictus-to-presentation, ictus-to-neurosurgical centre, ictus-to-treatment and transfer times were collected. …

Evaluation Of A Sleep Health Composite: Changes In Sleep Over The Menarcheal Transition Among Girls, Julianna Adornetti

Master's Theses

Sleep undergoes a shift during puberty, increasing the risk for psychological and insomnia symptoms, particularly among girls. However, little research has examined how the onset of menarche may contribute to vulnerability in sleep and psychological functioning. The Sleep Health framework provides a standardized, multidimensional way to conceptualize sleep health (RU-SATED: satisfaction, alertness, timing, efficiency, duration, and regularity). Although prior studies have provided proof-of-concept for assessing sleep health using a composite score (SHc), its measurement properties have yet to be explored. The primary aims of this longitudinal study were to (1) evaluate the factor structure of a sleep health composite, (2) …
