Light treatment in depression: An antique treatment with new insights
The use of light for its antidepressant action dates back to the beginnings of civilization. As early as 4700 y ago, Wong Tai mentioned the fluctuation of diseases with seasons, Hippocrates wrote on the interrelation between seasonal climates and mood (melancholia and mania) [1], and Aretaeus of Cappadocia prescribed, in the second century AD, that “Lethargi cs be laid in the light, and exposed to the rays of the sun, for the disease is gloom”. While being reported for millennia, bright light therapy (BLT) in depression was not officially recognized until 30 y ago for treating the Seasonal Affective Disorder (SAD),...

Maternal sleep during pregnancy and poor fetal outcomes: A scoping review of the literature with meta-analysis
There is a wealth of evidence to say that sleep impacts maternal health during pregnancy, however, little has been published on fetal health and maternal sleep. This scoping review summarises current literature on maternal sleep including sleep disordered breathing, sleep quality, sleep duration and supine sleep position, as these relate to fetal outcomes specifically birth weight, growth, preterm birth and stillbirth.An overall interpretation of the studies evaluated shows that events occurring during maternal sleep such as obstructive sleep apnea, sleep disruption and sleep position may have a negative effect on the fetu...

Individual vulnerability to insomnia, excessive sleepiness and shift work disorder amongst healthcare shift workers. A systematic review
Shift workers often experience reduced sleep quality, duration and/or excessive sleepiness due to the imposed conflict between work and their circadian system. About 20-30% of shift workers experience prominent insomnia symptoms and excessive daytime sleepiness consistent with the circadian rhythm sleep disorder known as shift work disorder. Individual factors may influence this vulnerability to shift work disorder or sleep-related impairment associated with shift work. This paper was registered with Prospero and was conducted using recommended standards for systematic reviews and meta-analyses. (Source: Sleep Medicine Reviews)

Altered Ultradian Cortisol Rhythmicity as a Potential Neurobiologic Substrate for Chronic Insomnia
Chronic insomnia is highly prevalent and associated with significant morbidity (i.e., confers risk for multiple psychiatric and medical disorders, such as depression and hypertension). Therefore, it is essential to identify factors that perpetuate this disorder. One candidate factor in the neurobiology of chronic insomnia is hypothalamic-pituitary-adrenal-axis dysregulation, and in particular, alterations in circadian cortisol rhythmicity. Cortisol secretory patterns, however, fluctuate with both a circadian and an ultradian rhythm (i.e., pulses every 60-120 minutes). (Source: Sleep Medicine Reviews)

Consolidative mechanisms of emotional processing in REM sleep and PTSD
Research suggests sleep plays a role in the consolidation of recently acquired memories for long-term storage. rapid eye movement (REM) sleep has been shown to play a complex role in emotional-memory processing, and may be involved in subsequent waking-day emotional reactivity and amygdala responsivity. Interaction of the hippocampus and basolateral amygdala with the medial-prefrontal cortex is associated with sleep-dependent learning and emotional memory processing. REM is also implicated in post-traumatic stress disorder (PTSD), which is characterized by sleep disturbance, heightened reactivity to fearful stimuli, and ni...

Dental and skeletal changes associated with long-term oral appliance use for obstructive sleep apnea: A systematic review and meta-analysis
An oral appliance (OA) is an effective treatment option for patients with obstructive sleep apnea (OSA), but dental and skeletal changes have been detected by many studies after long-term OA use. Better understanding of the long-term side effects may decrease discontinuation of OA use and assist clinicians to make informed decisions. Accordingly, a systematic review and meta-analysis were performed to evaluate the dental and skeletal changes associated with OAs designed to advance the mandible. The quality of the studies was determined by using the risk of bias assessment tool for non-randomized studies (RoBANS), and 12 st...

A review on drug-induced sedation endoscopy – Technique, grading systems and controversies
Sleep disordered breathing (SDB) comprises a spectrum of disorders, ranging from simple snoring to severe obstructive sleep apnoea (OSA), with a significant burden to health care systems in high income countries. If left untreated, OSA has significant cumulative, long-term health consequences. In the 1990s drug induced sedation endoscopy (DISE) has been developed to become a primary tool in the diagnosis and management of OSA. It allows meticulous endoscopic evaluation of the airway and identifies areas of collapse, thereby informing both on the selection of surgical techniques, where efficacy depends entirely on success a...

Short and Sweet: A Commentary on Short Sleep Duration and Hyperglycemia in Pregnancy
In their meta-analysis of 12 studies, Reutrakul and colleagues unequivocally conclude that short sleep duration is a risk for hyperglycemia in pregnancy, also known as gestational diabetes mellitus (GDM) [1]. This should not be surprising, since short sleep duration is a known risk factor for Type 2 diabetes in the general adult population. In GDM, however, it is twice as serious because two patients, mother and fetus, are impacted by hyperglycemia. The mother may require early induction of labor because the fetus is getting too large for gestational age, a cesarean birth is highly likely, the newborn may require intervent...

Devices for Home Detection of Obstructive Sleep Apnea: A Review
One of the most common sleep-related disorders is obstructive sleep apnea, characterized by a reduction of airflow while breathing during sleep and cause significant health problems. This disorder is mainly diagnosed in sleep labs with polysomnography, involving high costs and stress for the patient. To address this situation multiple systems have been proposed to conduct the examination and analysis in the patient ’s home, using sensors to detect physiological signals that are examined by algorithms.
