P108 Association of drowsiness events with a combination of sleep loss and other work metrics Open
Introduction Heavy vehicle drivers (HVDs), carrying approximately 75% of non-bulk domestic freight on Australian roads, are at risk of drowsiness due to night-time, long drives, or short sleep. Drowsiness comprises 46% of all driver-impair…
View article: Polysomnographic analysis of maternal sleep position and its relationship to pregnancy complications and sleep-disordered breathing
Polysomnographic analysis of maternal sleep position and its relationship to pregnancy complications and sleep-disordered breathing Open
Links between supine “going to sleep” position and stillbirth risk have led to campaigns regarding safe maternal sleep position. This study profiles the distribution of sleep positions overnight and relationships to sleep onset position du…

P133 Backward Rotating Shifts are Associated with Real-Time Drowsiness During Daytime Drives in Heavy Vehicle Drivers Open
Purpose While 10–20% of heavy vehicle crashes (HVDs) are drowsiness-related, the contributions of subsequent shifts to chronic drowsiness in HVDs is largely unknown. Eye-blink parameters indicate driver drowsiness reliably. This study exam…

P160 A trial of a position modification device for the prevention of supine sleep during pregnancy Open
Self-reported supine position at sleep onset during late pregnancy is related to a 2.6x increase in stillbirth risk, possibly due to the enlarged uterus compressing major blood vessels supplying the placenta. This study aimed to test the e…

Does continuous positive airways pressure treatment improve clinical depression in obstructive sleep apnea? A randomized wait‐list controlled study Open
Treatment of OSA may be a novel approach for the management and treatment of clinical depression in those with comorbid sleep disordered breathing. Larger trials of individuals with clinical depression and comorbid OSA are needed.

Sleep-disordered breathing does not impact maternal outcomes in women with hypertensive disorders of pregnancy Open
The presence of SDB during pregnancy did not worsen the disease course of GH or PE, and was not associated with high blood pressure or anti-angiogenic markers of hypertensive disease amongst healthy pregnant women. Given the numerous repor…
