Circadian Rhythm
PMID: 32130879 DOI: 10.1016/j.cmet.2020.02.008 Abstract The microbiota-gut-brain axis encompasses a bidirectional mode of communication between the microorganisms residing in our gut, and our brain function and behavior. The composition of the gut microbiota is subject to diurnal variation and is entrained by host circadian rhythms. In turn, a diverse microbiota is essential for optimal regulation of host circadian...

PMID: 32029066 DOI: 10.5664/jcsm.8340 Abstract Study objective: To evaluate the independent association between sleep disordered breathing (SDB) using overnight polysomnography (PSG) and left ventricular (LV) scar using cardiac magnetic resonance (CMR) with late-gadolinium enhancement (LGE) in a community based cohort of the Multi-ethnic Study of Atherosclerosis (MESA). Methods: Our analytical sample includes 934 participants from the fifth examination of MESA...

Front. Microbiol., 21 January 2020 | https://doi.org/10.3389/fmicb.2019.03145 Abstract The interplay between genetic and environmental risk factors contributes to the pathogenesis of metabolic disease. Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder in women of reproductive age. Circadian rhythm disruption is an important risk factor for PCOS. In this study, we evaluated the...

https://doi.org/10.1016/j.envint.2019.105184 Abstract Exposure to light at inappropriate times in relation to the solar cycle can disturb circadian endocrine and metabolic rhythms. Previous studies have suggested an association between light exposure at night (LAN) and obesity, an important risk factor of atherosclerosis, although it remains unclear whether LAN associates with progression of atherosclerosis. To evaluate the...
