Adequate sleep is important for good health, but it is not always easy to achieve because of social factors. Daytime napping is widely prevalent around the world. We performed a meta-analysis to investigate the association between napping (or excessive daytime sleepiness: EDS) and the risk of type 2 diabetes or metabolic syndrome, and to quantify the potential dose-response relation using cubic spline models. Electronic databases were searched for articles published up to 2016, with 288,883 Asian and Western subjects...

In recent years, strong evidence has emerged suggesting that insufficient duration, quality, and/or timing of sleep are associated with cardiovascular disease (CVD), and various mechanisms for this association have been proposed. Such associations may be related to endophenotypic features of the sleep homeostat and the circadian oscillator, or may be state-like effects of the environment. Here, we review recent literature on sleep, circadian rhythms and CVD with a specific emphasis on differences between racial/ethnic groups...

For the recent years, a special attention is given to the non-motor symptoms of Parkinson's disease, including sleep/wake disorders representing one of the leading symptoms. Daytime sleepiness occurs in 30-55% of patients depending on duration and stage of the disease, leading to severe maladjustment. This symptom seems to be multifactorial by nature and identification of it's causes could have a great importance for the therapy. The main factors of the development of daytime sleepiness in Parkinson's disease and key points of the pathogenesis of «primary» daytime sleepiness are discussed...
