Interactions between sleep, stress, and metabolism: From physiological to pathological conditions

TL;DR: Quick light normalization exam (qLiNE) is described that transforms ubiquitous smartphones into a robust LFA reader that adapted qLiNE to detect cortisol, a known stress hormone, in saliva samples at point-of-use settings.

TL;DR: This study investigates the association between self-reported sleep and cognitive function in 80 patients with mild cognitive impairment, finding significant correlations between poorer sleep quality and reduced frontal and executive functions, particularly in executive domains.

TL;DR: This study aimed to investigate the effect of a 3-Hz binaural beat on sleep stages, which is considered a behavioral state and showed that the N3 duration of the experimental group was longer than that of the control group, and the N2duration of the Experimental group was shorter than thatof the controlgroup.

TL;DR: In conclusion, participants with good sleep quality were 4.705 times more likely to have longer G-tolerance test time and pre-pilots should also improve their sleep quality to pass the G-tolerance test.

TL;DR: Differences in leptin and ghrelin are likely to increase appetite, possibly explaining the increased BMI observed with short sleep duration, and changes in appetite regulatory hormones with sleep curtailment may contribute to obesity.

TL;DR: In this study, 12 young, healthy, normal-weight men exhibited reductions in the satiety hormone leptin, increases in the hunger hormone ghrelin, and increases in hunger after 2 nights of only 4 hours of sleep compared with after two nights of 10 hours ofSleep, suggesting inadequate sleep seems to influence the hormones that regulate satiety and hunger.

TL;DR: In this article, a meta-analysis was carried out to assess whether the evidence supports the presence of a relationship between short sleep duration and obesity at different ages, and to obtain a quantitative estimate of the risk in order to assess the consistency and potential public health relevance.

TL;DR: Increased adipocyte 11β HSD-1 activity may be a common molecular etiology for visceral obesity and the metabolic syndrome.
