Internet addiction and sleep problems: A systematic review and meta-analysis.

The pathological use of the internet - conceptualized as 'internet addiction' - might be crucial in initiating and increasing sleep disturbances in the community. While inconsistent evidence is reported regarding the association of internet addiction and sleep disturbances, the severity of this association remains unclear. This systematic review and meta-analysis were conducted to increase our understanding of the relationship between internet addiction and sleep disturbances. A systematic review was conduc...

Validity, potential clinical utility, and comparison of consumer and research-grade activity trackers in Insomnia Disorder I: In-lab validation against polysomnography.

Consumer activity trackers claiming to measure sleep/wake patterns are ubiquitous within clinical and consumer settings. However, validation of these devices in sleep disorder populations are lacking. We examined 1 night of sleep in 42 individuals with insomnia (mean = 49.14 ± 17.54 years) using polysomnography, a wrist actigraph (Actiwatch Spectrum Pro: AWS) and a consumer activity tracker (Fitbit Alta HR: FBA). Epoch-by-epoch analysis and Bland-Altman methods evaluated each device against polysomn...

The Epworth Sleepiness Scale in Service Members with Sleep Disorders.

Excessive daytime sleepiness affects an estimated 20% of the general population. While the prevalence of sleepiness in the military is largely unknown, it is well established that short sleep duration is endemic. The reasons for this include: the demanding nature of their duties, shift work and 24-hour duty periods, deployments and exigencies of military service as well as sleep disorders. The Epworth Sleepiness Scale (ESS) is the most widely used sleep questionnaire and provides a self-assessment of daytim...

Blocking the hype-hypocrisy-falsification-fakery pathway is needed to safeguard science.

In chemistry and other sciences, hype has become commonplace, compounded by the hypocrisy of those who tolerate or encourage it while disapproving of the consequences. This reduces the credibility and trust upon which all science depends for support. Moreover, hype and hypocrisy are but first steps down a slippery slope towards falsification of results and dissemination of fake science. Systemic drivers in the contemporary structure of the science establishment encourage exaggeration and may lure the indivi...

Accuracy and utility of a pacemaker respiratory monitoring algorithm for the detection of obstructive sleep apnea in patients with atrial fibrillation.

The usefulness and diagnostic value of new-generation pacemakers (PM) with enhanced monitoring capabilities are not yet clearly established. The aim of this study was to evaluate the diagnostic utility and accuracy of a PM-incorporated respiratory monitoring algorithm and its interaction with atrial fibrillation (AF).

Tai Chi exercise for sleep problems in older adults: A protocol of systematic review and meta-analysis.

Sleep plays a crucial role in the general health of the human body. However, sleep problems become increasingly severe with age, and its incidence is on the rise. Notably, Tai Chi exercise may be an efficacious means to ameliorate sleep problems among older adults. This is especially since Tai Chi has been widely used to manage sleep problems in China for many years, but there is limited evidence regarding its effectiveness. We will conduct this study aiming to investigate the efficacy of Tai Chi as a compl...

Clinical and Video-Polysomnographic Analysis of Rem Sleep Behavior Disorder and other Sleep Disturbances in Dementia with Lewy Bodies.

To study REM sleep behavior disorder (RBD) and other sleep disorders in dementia with Lewy bodies (DLB).

Vigilance declines following sleep deprivation are associated with two previously identified dynamic connectivity states.

Robustly linking dynamic functional connectivity (DFC) states to behaviour is important for establishing the utility of the method as a functional measurement. We previously used a sliding window approach to identify two dynamic connectivity states (DCS) related to vigilance. A new sample of 32 healthy participants underwent two sets of task-free functional magnetic resonance imaging (fMRI) scans, once in a well-rested state and once after a single night of total sleep deprivation. Using a temporal differen...

Promoting sleep and circadian health may prevent postoperative delirium: A systematic review and meta-analysis of randomized clinical trials.

This systematic review with meta-analysis and trial sequential analysis of randomized clinical trials aimed to clarify the efficacy of sleep and circadian interventions on preventing postoperative delirium. The search and screening identified 13 trials with great heterogeneity in interventions, surgery types as well as methods for evaluating delirium, sleep and circadian rhythms. Meta-analyses revealed that sleep and circadian interventions were associated with decreased incidences of postoperative delirium...

Sleepless in Beirut: sleep duration and associated subjective sleep insufficiency, daytime fatigue, and sleep debt in an urban environment.

Insufficient sleep is not well studied in developing countries. We assessed sleep duration among adults in Lebanon and examined its potential predictors and relationship with subjective sleep insufficiency, daytime fatigue, and weekday sleep debt.

Why healthy sleep is good for business.

People spend large portions of their lives working, often to the detriment of sleep. Businesses often ignore the importance of employee sleep despite evidence showing sleep health is crucial to positive employee outcomes. In this review we address the effect of sleep on employee health, performance, and workplace relationships. We examine the impact of work characteristics on employee sleep. Finally, we discuss opportunities for businesses to improve employee sleep to maximize success.

Genetic contribution in primary sleep disorders

Sleep disorders are disturbances of sleep patterns, habits and sleep process, which can affect the onset stage, maintenance stage, or sleep-wake cycle. Sleep and sleep wake disorders are complex phenotypes regulated by various genes, environment, and interaction between them. Primary sleep disorders appear as a consequence of endogenous alterations in the mechanisms of the sleep-wake cycle, which are often aggravated by other factors. At present, genetic studies related to the molecular basis of sleep disor...

The effects of sleep on prospective memory: A systematic review and meta-analysis.

Prospective memory (PM) enables us to execute previously conceived intentions at a later time and is used when remembering to call a friend or submitting a proposal on time. Evidence that sleep benefits PM is presently mixed. Further, when a benefit is observed, it is unclear if this is achieved through improvements in strategic monitoring (maintaining an intention in mind and searching for cues) or spontaneous retrieval (an automatic process occurring without preparatory attention). We conducted a meta-ana...

The impact of cognitive behavioural therapy for insomnia on objective sleep parameters: A meta-analysis and systematic review.

It is well-established that cognitive behavioural therapy for insomnia (CBT-I) improves self-reported sleep disturbance, however the impact on objective sleep is less clear. This meta-analysis aimed to quantify the impact of multi-component CBT-I on objective measures of sleep, indexed via polysomnography (PSG) and actigraphy. Fifteen studies met inclusion criteria. Following appraisal for risk of bias, extracted data were meta-analysed using random-effects models. The quality of the literature was generall...

Sleep in posttraumatic stress disorder: A systematic review and meta-analysis of polysomnographic findings.

Polysomnographic studies have been performed to examine sleep abnormalities in posttraumatic stress disorder (PTSD), but clear associations between PTSD and sleep disturbances have not been established. A systematic review of the evidence examining the polysomnographic changes in PTSD patients compared with controls was conducted using MEDLINE, EMBASE, All EBM databases, PsycINFO, and CINAHL databases. Meta-analysis was undertaken where possible. The searches identified 34 studies, 31 of which were appropri...

Analysis of sleep structure and related factors in children with severe obstructive sleep apnea-hypopnea syndrome.

To investigate the sleep structure and related factors in children with severe obstructive sleep apnea-hypopnea syndrome(OSAHS). We summarized the characteristics of 250 children withsevere OSAHS diagnosed by polysomnography(PSG)in our hospital from January 1, 2017 to December 31, 2017. According to AHI, the patients were divided into three groups, 159 in group A with 20 < AHI≤0, 57 in group B with 40 < AHI≤60, and 34 in group C with AHI > 60. We collected the basic data, sleep parameters (sleep ef...

Evaluation of a magnesium ring device for mechanical augmentation of a ruptured ACL: Finite element analysis.

Recently, a ring device was used for mechanical augmentation to aid the healing of ACL. In-vivo study using goat showed improved joint stability after ring repair in comparison to using biological augmentation alone.

Subjective sleep problems and sleep hygiene among adolescents having depression: A case-control study.

Sleep research has often focussed heavily on polysomnography while ignoring subjective sleep complaints of individuals, especially the young ones. Discordance has been seen between objective and subjective parameters of sleep among children and adolescents. There has been a trend towards worsening of sleep hygiene among adolescents, which may predispose to psychiatric disorders like depression. So, we compared the subjective sleep quality and sleep hygiene among depressed and normal adolescents. A sample of...

Quantitative EEG measures in REM and NREM sleep are associated with AHI and nocturnal hypoxemia in men.

Quantitative EEG measures of sleep may identify vulnerability to obstructive sleep apnea (OSA) sequelae, however, small clinical studies of sleep microarchitecture in OSA show inconsistent alterations. We examined relationships between quantitative EEG measures during rapid eye movement (REM) and non-REM (NREM) sleep and OSA severity among a large population-based sample of men while accounting for insomnia.

Chronotherapy for the rapid treatment of depression: A meta-analysis.

Chronotherapy (sleep deprivation, sleep phase shifting and/or the use of bright light) combines non-invasive and non-pharmacological interventions that may act rapidly against depressive symptoms. However, to date no meta-analysis has been conducted to examine their effectiveness.

Child sleep behaviors and sleep problems from infancy to school-age.

Few studies have examined the sleep behaviors associated with a caregiver-reported sleep problem beyond early childhood and across different age groups. This study examined sleep behaviors associated with a caregiver-reported sleep problem from birth to middle childhood.

Sleep debt: the impact of weekday sleep deprivation on cardiovascular health in older women.

Short sleep duration is associated with increased cardiovascular disease (CVD) risk. However, it is uncertain whether sleep debt, a measure of sleep deficiency during the week compared to the weekend, confers increased cardiovascular risk. Because sleep disturbances increase with age particularly in women, we examined the relationship between sleep debt and ideal cardiovascular health (ICH) in older women.
