More variable circadian rhythms in epilepsy captured by long‐term heart rate recordings from wearable sensors

Epilepsia, EarlyView.
Abstract Objective The circadian rhythm synchronizes physiological and behavioral patterns with the 24‐h light–dark cycle. Disruption to the circadian rhythm is linked to various health conditions, although optimal methods to describe these disruptions remain unclear.

Bruxism and Stress: Ultrasonographic Masseter Muscle Assessment and Salivary Melatonin‐Cortisol Dynamics

Journal of Oral Rehabilitation, EarlyView.
ABSTRACT Background Bruxism is a parafunctional activity characterised by teeth grinding or clenching, often associated with stress and neurophysiological factors. Its aetiology is multifactorial, with recent studies emphasising neurotransmitters and hormonal imbalances, particularly melatonin and cortisol. This study assesses masseter muscle thickness

Predictability of individual circadian phase during daily routine for medical applications of circadian clocks [PDF]

, 2019
Background: Circadian timing of treatments can largely improve tolerability and efficacy in patients. Thus, drug metabolism and cell cycle are controlled by molecular clocks in each cell, and coordinated by the core body temperature 24-hour rhythm, which

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

Chronotype and biological rhythms in bipolar disorders

European Psychiatry, 2021
Introduction Biological rhythms play an important role in the etiology of mood disorders. Several lines of evidence established a link between circadian rhythm disruption and mood episodes.

Gene expression associated with early and late chronotypes in Drosophila melanogaster [PDF]

, 2015
The circadian clock provides the temporal framework for rhythmic behavioral and metabolic functions. In the modern era of industrialization, work, and social pressures, clock function is jeopardized, and can result in adverse and chronic effects on ...

Chronotype in relation to shift work: A cohort study among 37,731 female nurses

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Chronotype may affect tolerance for circadian disruption induced by shift work. This study examines the association between chronotype, self‐reported sleep timing, shift type preference, and sleep problems among nurses, and studies chronotype stability over time.

Early-Morning and Late-Night Maximal Runs: Metabolic and Perceived Exertion Outcomes

, 2020
People may exercise at the ends of their day to fit activity into their schedule; the purpose of this investigation was to determine if metabolic or perceived exertion outcomes differed between maximal runs early in the morning and late at night.

Sleep disruption, chronotype, shift work, and prostate cancer risk and mortality : a 30-year prospective cohort study of Finnish twins [PDF]

, 2016
Sleep disruption and shift work have been associated with cancer risk, but epidemiologic evidence for prostate cancer remains limited. We aimed to prospectively investigate the association between midlife sleep- and circadian-related parameters and later

Multidimensional frailty and sleep quality in late adulthood: A UK biobank examination

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Frailty and sleep disturbances are two major concerns in late adulthood, that not only profoundly threaten health and wellbeing at the individual level but place enormous demands on our healthcare systems. Given that both constructs represent dynamic states that are preventable and reversible, understanding the potential pathways to and effects
