Diabetes has become the world' s major public health problem in the 21(th) century. Increasing attention has been paid to the importance of healthy sleep abroad, whereas less attention has been paid to it in China. Through literature study, this paper summarizes the current status of epidemiology and laboratory research on the relationship between sleep duration and incidence of type 2 diabetes, insulin sensitivity and blood glucose control both at home and abroad, and introduces the underlying mechanisms in order to provide evidence for further studies and the prevention and management of diabetes...

Brenda R Whitehead, Jessica M Blaxton
Purpose of the Study: There is little debate that maintaining some level of physical activity in later life conveys positive benefits both physically and psychologically. What is less understood is the extent to which the type of activity or the length of time spent doing it matters when it comes to these benefits on the daily level. Here, we investigated (a) whether the presence of daily purposeful exercise (Exercise) or non-exercise physical activity (Activity) is sufficient for experiencing day-level benefits, or if time spent matters, and (b) whether there are differential well-being benefits of Exercise and Activity on the daily level...

Study Objectives: In young adults, napping is hypothesized to benefit episodic memory retention (e.g., via consolidation). Whether this relationship is present in older adults has not been adequately tested, but is an important question because older adults display marked changes in sleep and memory. Design: Between-subjects design. Setting: Sleep laboratory at Emory University School of Medicine. Participants: 50 healthy young adults (18-29) and 45 community dwelling older adults (58-83)...

Objective: Older adults frequently report sleep problems and are at increased risk for cardiometabolic disruption. Experimental sleep restriction of younger adults has suggested that cortisol may be on the pathway between sleep restriction and cardiometabolic disease. We investigated whether the natural variation in sleep among older adults is associated with daytime cortisol level. Methods: Salivary cortisol samples and actigraphy sleep data were collected from a random subsample of participants in the National Social Life, Health and Aging Project, a nationally-representative probability sample of adults aged 62-90 (N=672)...

Study Objectives: Pre-diagnosis lifestyle factors can influence colorectal cancer (CRC) survival. Sleep deficiency is linked to metabolic dysfunction and chronic inflammation, which may contribute to higher mortality from cardiometabolic conditions and promote tumor progression. We hypothesized that pre-diagnosis sleep deficiency would be associated with poor CRC survival. No previous study has examined either nighttime sleep or daytime napping in relation to survival among men and women diagnosed with CRC...

Study Objectives: Recent studies implicate inadequate sleep duration and quality in metabolic disease. Fewer studies have examined the timing of sleep, which may be important because of its potential impact on circadian rhythms of metabolic function. We examined the association between sleep timing and metabolic risk among Hispanic/Latino adults. Methods.: Cross-sectional data from community-based study of 13,429 participants aged 18-74 years. People taking diabetes medications were excluded...

Objective: To assess the associations between sleep duration and cardiometabolic risk factors in Chinese school-aged children and to explore the possible mediating role of adipokines. Methods: Sleep duration was collected in 3,166 children from the Beijing Child and Adolescent Metabolic Syndrome study. Glucose homeostasis and other cardiometabolic risk factors were assessed. Serum adipokines including leptin, total and high-molecular-weight (HMW) adiponectin, resistin, fibroblast growth factor 21 (FGF21) and retinol binding protein 4 (RBP4) were determined...

Background: Despite the widespread belief that napping is common among older adults, little is known about the correlates of napping. We examined the prevalence and correlates of self-reported and objectively measured napping among very old women. Methods: We studied 2,675 community-dwelling women (mean age 84.5 ± 3.7 years; range 79-96). Self-reported napping was defined as a report of regular napping for ≥1 hour per day. Individual objective naps were defined as ≥5 consecutive minutes of inactivity as measured by actigraphy and women were characterized as "objective nappers" if they had at least 60 minutes of naps per day...

BACKGROUND: On a pharmacologic basis, levobupivacaine is expected to last longer than ropivacaine. However, most reports of these anesthetics for brachial plexus block do not suggest a difference in analgesic effect. The aim of this study is to compare the postoperative analgesic effects of levobupivacaine and ropivacaine when used for treating ultrasound-guided brachial plexus block. METHODS: A total of 62 patients undergoing orthopedic surgery procedures were prospectively enrolled and randomized to receive levobupivacaine (group L, N = 31) or ropivacaine (group R, N = 31)...

Research on sleep loss and vigilance both focus on declines in cognitive performance, but theoretical accounts have developed largely in parallel in these two areas. In addition, computational instantiations of theoretical accounts are rare. The current work uses computational modeling to explore whether the same mechanisms can account for the effects of both sleep loss and time on task on performance. A classic task used in the sleep deprivation literature, the Psychomotor Vigilance Test (PVT), was extended from the typical 10-min duration to 35 min, to make the task similar in duration to traditional vigilance tasks...

RATIONALE: Obstructive sleep apnea (OSA) can affect not only sleep quality but also sleep duration. Determining the therapeutic effects of continuous positive airway pressure (CPAP) on habitual sleep profiles may shed light on the impact of OSA on sleep duration. OBJECTIVES: To determine whether and how CPAP affects habitual sleep duration in patients with OSA. METHODS: Assessments of sleep duration and sleep quality were performed on 57 newly diagnosed study subjects with OSA (46 men, median 63 years, apnea-hypopnea index >20 h-1) at baseline and 3 months after initiation of CPAP therapy...

Horses can sleep while standing; however, recumbency is required for rapid eye movement (REM) sleep and therefore essential. Previous research indicated a minimal duration of recumbency of 30 min per 24 h to perform a minimal duration of REM sleep. For group-housed horses, suitable lying area represents a potentially limited resource. In Switzerland, minimal dimensions for the space allowance of the littered area are therefore legally required. To assess the effect of different space allowances of the littered area on lying behavior, 38 horses in 8 groups were exposed to 4 treatments for 11 days each; T0: no litter provided, T0...

Why we sleep remains one of the greatest mysteries in science. In the past few years, great advances have been made to better understand this phenomenon. Human genetics has contributed significantly to this movement, as many features of sleep have been found to be heritable. Discoveries about these genetic variations that affect human sleep will aid us in understanding the underlying mechanism of sleep. Here we summarize recent discoveries about the genetic variations affecting the timing of sleep, duration of sleep and EEG patterns...

Fibrolipomas are benign lesions conformed by fat and connective tissue, classified as histologic variants of lipomas. They are rarely located in the head and neck and represent less than 0.6% of the benign tumors of the larynx and hypopharynx. Their clinical presentation depends on its location and size. We present the case of a 51-year-old male patient who reported progressive dyspnea, dysphagia and obstructive sleep symptoms with a duration of 3 months, without apparent cause. A pharyngolaryngeal fiberoptic endoscopy showed a smooth, rounded mass in the posterior wall of the hypopharynx, partially obstructing the laryngeal vestibule, creating a valve effect...
