Short Sleep Duration Measured by Smartwatch Is Associated With Elevated Resting Heart Rate and Reduced Nocturnal Oxygen Saturation: Insights From Heartbeat

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
Short Sleep Duration and Wearable‐Derived Cardiovascular Metrics. ABSTRACT Introduction Sleep duration has been shown to impact cardiovascular outcomes; however, the impact on wearable‐derived metrics such as oxygen saturation and resting heart rate remains underinvestigated.

Annual Research Review: What processes are dysregulated among emotionally dysregulated youth? – a systematic review

open access: yesJournal of Child Psychology and Psychiatry, Volume 66, Issue 4, Page 516-546, April 2025.
Proliferation of the term “emotion dysregulation” in child psychopathology parallels the growing interest in processes that influence negative emotional reactivity. While it commonly refers to a clinical phenotype where intense anger leads to behavioral dyscontrol, the term implies etiology because anything that is dysregulated requires an impaired ...

Autonomic Function in Fragile X Syndrome: A Systematic Review

open access: yesJournal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Fragile X syndrome (FXS) is a monogenic X‐linked cause of intellectual disability and autism. Individuals with FXS often have high levels of anxiety and sometimes display challenging behaviours. Autonomic dysfunction has been suggested to be one physiological mechanism that may contribute to these.

Neural modulation of ocular immunity: Exploring a sympathetic‐macrophage neuroimmune link in the human ciliary body

open access: yesJournal of Anatomy, EarlyView.
Using microscopy and 3D confocal imaging on seven cadaveric eyes, we identified sympathetic nerves closely associated with β₂‐adrenergic receptor‐expressing macrophages in the human ciliary body (CB). These findings suggest a sympathetic‐macrophage neuroimmune link in the CB, potentially influencing ocular inflammation and degeneration, warranting ...

The dynamics of cyclic‐periodic phenomena during non‐rapid and rapid eye movement sleep

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is a complex physiological state characterized by distinct stages, each exhibiting unique electroencephalographic patterns and physiological phenomena. Sleep research has unveiled the presence of intricate cyclic‐periodic phenomena during both non‐rapid eye movement and rapid eye movement sleep stages. These phenomena encompass a spectrum

Sleep and cardiac autonomic modulation in older adults: Insights from an at‐home study with auditory deep sleep stimulation

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The autonomic nervous system regulates cardiovascular activity during sleep, likely impacting cardiovascular health. Aging, a primary cardiovascular risk factor, is associated with cardiac autonomic disbalance and diminished sleep slow waves. Therefore, slow waves may be linked to aging, autonomic activity and cardiovascular health. However, it

Screens, Teens, and Sleep: Is the Impact of Nighttime Screen Use on Sleep Driven by Physiological Arousal?

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT Few studies have objectively measured both screens and sleep in real‐world settings. This study uses repeated measures to assess heart rate during evening screen use, providing new insights into how these behaviours relate to adolescent sleep. Screen use was recorded using wearable cameras over four nights in 70 youth (37% indigenous Māori, 42%
