Sleep extension reduces pain sensitivity
Insufficient sleep increases pain sensitivity in healthy individuals. Additionally, extending sleep (e.g., increasing nocturnal sleep time or adding a mid-day nap) has been shown to restore pain sensitivity to baseline levels in sleep deprived/restricted individuals. Whether sleep extension can reduce pain sensitivity beyond baseline levels in non-sleep restricted/deprived individuals remains unknown. In a sample of 27 healthy, pain-free, normally-sleeping individuals (17 males, mean age ∼24 yrs), we examined the impact of five nights of sleep extension on pain sensitivity.

P-wave dispersion as a simple tool for screening childhood obstructive sleep apnea syndrome
The gold standard for the diagnosis of childhood obstructive sleep apnea syndrome (OSAS) diagnosis is polysomnography; however, electrocardiography (ECG) may provide a simpler alternative. P-wave dispersion (PWD), the difference between the maximum and minimum P-wave duration measured by 12-lead ECG, is increased in adult OSAS but has not been researched in childhood OSAS. The aims of this study were to determine the PWD and cut-off value for the diagnosis of childhood OSAS and its association with severity. (Source: Sleep Medicine)

Response to “The dark side of adherence” by Crawford and Vallieres
We agree with Crawford and Vallieres that the discontinuation of positive airway pressure (PAP) treatment in patients with sleep-disordered breathing does not depend on just one modality of variables. In our recently published registry-based study, we evaluated only biomedical variables since those were the only ones reported into the registry [1]. We did not have access to the medical journals and further analysis and evaluation of other aspects of patient characteristics was not possible. PAP failure can have devastating consequences and there is a need for a holistic approach to prevent suboptimal adherence. (Source: Sleep Medicine)

We were pleased to see Palm and colleagues reporting on adherence to positive airway pressure (PAP) treatment for obstructive sleep apnoea (OSA) in Sleep Medicine, volume 51 [1]. Their study has multiple strengths: sample size (n=16,425), length of follow-up (1.2yrs) and an under-researched population (Sweden). Significant predictors of PAP adherence were humidifier use, increased age, OSA severity and weight. We would like to use this opportunity to highlight that in addition to such biomedical (eg, BMI, disease severity etc.) and psychosocial factors (eg, self-efficacy, depression, support), we have to take sleep into ac...

Sleep Influences On Cardio-Metabolic Health In Indigenous Populations
Indigenous populations continue to be among the world's most marginalized population groups. Studies in Indigenous populations from high income countries (including the United States, Canada, Australia and New Zealand) indicate increased risk of sleep disorders compared to non-Indigenous populations. Poor sleep, whether it be short sleep duration or fragmented sleep, is a well-established risk factor for cardio-metabolic diseases. Given the implications, targeted improvement of poor sleep may be beneficial for the health and well-being of Indigenous people. (Source: Sleep Medicine)

Obstructive events in children with Prader-Willi syndrome occur predominantly during rapid eye movement sleep
Children with Prader-Willi syndrome (PWS) have a high prevalence of obstructive sleep apnea syndrome (OSAS). In most typically developing children with OSAS, more obstructive apneas and hypopneas occur during rapid eye movement (REM) than during non-REM (NREM) sleep. It was hypothesized that patients with PWS are even more prone to obstructive events in REM sleep than otherwise healthy subjects with OSAS. (Source: Sleep Medicine)
