TL;DR: Using the dominance ranking framework, CBT-I was cost-effective compared to pharmacotherapy or no treatment and future studies are encouraged to employ longer time-horizons and larger sample sizes to enable better determination of sustained cost and outcomes changes.

TL;DR: The theoretical mechanistic effects of CBTi in facilitating reduced sedative-hypnotic use are discussed, clear recommendations for future research are provided, and pragmatic clinical suggestions to increase access to CBTi are offered to reduce dependence on sedative -hypnotics as the 'default' treatment for insomnia are offered.

TL;DR: It is suggested that obesity, rather than OSA per se, determine testosterone concentration, which accords with the graded effect of weight loss, but limited effect of continuous positive airway pressure to increase testosterone and highlights the importance of managing obesity in men with low testosterone concentration.

TL;DR: Some objective measures of sleep were associated with subjective estimates of sleep duration and sleep quality, however, individuals may overestimate sleep onset latency and underestimate sleep duration during on-call periods.

TL;DR: Findings suggest impairments in HGS may be related to fat infiltration of muscle, hypoxemia-induced reductions in peripheral neural innervation, or even endothelial dysfunction, which is a common outcome ofhypoxemia.
