DOI: 10.1016/j.bbi.2017.07.117
Abstract: Two measures of host rhythmicity, rest/activity and diurnal cortisol secretion rhythms, have demonstrated prognostic significance across several cancer types. We previously reported a significant correlation between these two parameters among presurgical breast cancer patients. The… read more here.

DOI: 10.1016/j.ebiom.2020.102881
Abstract: Background We sought to investigate the possible associations of rest-activity patterns with cortical amyloid burden, medial temporal lobe (MTL) neurodegeneration, and cognitive function in patients in the early stage of cognitive impairment. Methods Rest-activity patterns… read more here.

DOI: 10.1080/07420528.2017.1337032
Abstract: ABSTRACT Rest-activity patterns provide an indication of circadian rhythmicity in the free-living setting. We aimed to describe the distributions of rest-activity patterns in a sample of adults and children across demographic variables. A sample of… read more here.

DOI: 10.1080/07420528.2020.1715998
Abstract: ABSTRACT The continuous, longitudinal nature of accelerometry monitoring is well-suited to capturing the regular 24-hour oscillations in human activity across the day, the cumulative effect of our circadian rhythm and behavior. Disruption of the circadian… read more here.

Sleep and Rest-Activity Rhythms in Recovering Patients with Severe Concurrent Mental and Substance Use Disorder: A Pilot Study
Sign Up to like & getrecommendations! Published in 2022 at "Journal of Dual Diagnosis"
DOI: 10.1080/15504263.2022.2157694
Abstract: Abstract Objective: Mental health and substance use disorders are commonly associated with disrupted sleep and circadian rest-activity rhythms. How these disorders in combination relate to sleep and circadian organization is not well studied. We provide… read more here.

DOI: 10.1093/sleep/zsaa056.030
Abstract: Diurnal variations in immune cell number and function are regarded important for immune competence and are thought to be mediated by rest-activity rhythms and hormones. Moreover, the photoperiod is also known to modulate the immune… read more here.

DOI: 10.1093/sleep/zsac027
Abstract: STUDY OBJECTIVES Age-related cataract decreases light transmission at the most sensitive spectrum for circadian photoentrainment, with negative ramifications for human health. Here, we assessed whether intraocular lens replacement (IOL) in older patients with previous cataract… read more here.

DOI: 10.1093/sleep/zsad077.0099
Abstract: In early childhood, irregular sleep schedules that may promote circadian rhythm misalignment predict greater weight gain. However, circadian rest-activity (CRA) rhythmicity in infancy in relation to growth is understudied. The aim of the present study… read more here.

DOI: 10.1093/sleep/zsad077.0107
Abstract: Non-parametric metrics of interdaily stability (IS), relative amplitude (RA), and intradaily variability (IV) characterize between- and within-day rest-activity rhythms. Prior research has reported differences in these metrics by age and race/ethnicity, but these differences have… read more here.
