PURPOSE OF REVIEW: Today's smartphones boast more computing power than the Apollo Guidance Computer. Given the ubiquity and popularity of smartphones, are we already carrying around miniaturized sleep labs in our pockets? RECENT FINDINGS: There is still a lack of validation studies for consumer sleep technologies in general and apps for monitoring sleep in particular. To overcome this gap, multidisciplinary teams are needed that focus on feasibility work at the intersection of software engineering, data science and clinical sleep medicine...

For sea level-based endurance athletes who compete at moderate and high altitudes, many are not logistically able to arrive at altitude weeks prior to the event to fully acclimatize. For those who can only arrive at altitude the night before competition, we asked if there is a physiological and performance advantage in reducing altitude exposure time to two hours prior to competition. On three separate visits, ten cyclists completed overnight laboratory exposures of: 1) a 14-hour exposure to normobaric hypoxia (16...

AIMS: We hypothesized that if we control for food composition, caloric intake, light exposure, sleep schedule, and exercise, intermittent fasting would not influence the circadian pattern of melatonin. Therefore, we designed this study to assess the effect of intermittent fasting on the circadian pattern of melatonin. METHODS: Eight healthy volunteers with a mean age of 26.6 ± 4.9 years and body mass index of 23.7 ± 3.5 kg/m(2) reported to the Sleep Disorders Center (the laboratory) on four occasions: (1) adaptation, (2) 4 weeks before Ramadan while performing Islamic intermittent fasting for 1 week (fasting outside Ramadan [FOR]), (3) 1 week before Ramadan (nonfasting baseline [BL]), and (4) during the 2(nd) week of Ramadan while fasting (Ramadan)...

INTRODUCTION: Obstructive sleep apnea (OSA) affects 1-5% of pediatric patients. Laboratory polysomnography is expensive, not always available, and is inconvenient for patients. Our study investigates the diagnostic ability of an unattended ambulatory monitor for the diagnosis of pediatric OSA. METHODS: A prospective study was conducted in children, ages 2-17. Subjects completed in-lab polysomnography simultaneously with ambulatory monitoring. Caregivers attempted home studies on two subsequent nights to compare the home monitor and the laboratory polysomnogram (PSG)...

OBJECTIVE: Obstructive sleep apnea is a common problem, requiring expensive in-lab polysomnography for proper diagnosis. Home monitoring can provide an alternative to in-lab testing for a subset of OSA patients. The objective of this project was to investigate the effect of incorporating home testing into an OSA program at a large, tertiary sleep disorders centre. METHODS: The Sleep Disorders Centre in Saskatoon, Canada, has been incorporating at-home testing into their diagnostic pathways since 2006...

BACKGROUND: Several studies have shown the effectiveness of reflexology in different health problems as well as obtaining a high degree of relaxation during its application. A previous study suggested a possible relation between the relaxation obtained during the reflexology session and the sleep. However, the design of the study did not provide evidence for this hypothesis. In this study, we use a polysomnogram to investigate the effects during its application. METHOD: Prospective experimental study conducted in a sleep laboratory...

PURPOSE OF REVIEW: This article provides a clinical approach to the appropriate investigation and diagnosis of sleep disorders commonly seen by neurologists. RECENT FINDINGS: Home sleep apnea testing in appropriate situations can replace laboratory polysomnography in many cases of uncomplicated sleep apnea. Multiple sleep latency tests must be performed meticulously and interpreted in the clinical setting to avoid overdiagnoses of narcolepsy. Human leukocyte antigen testing has limited utility in establishing a diagnosis of narcolepsy because a positive test has low specificity...

Background A thorough pre-operative evaluation is required prior to total joint arthroplasty (TJA). The objective of screening is to identify patient- and procedure-related risk constellations. Pre-operative diagnostic measures are vital in order to anticipate, reduce or even eliminate threats to patient safety. Furthermore, the clinical and radiographical workup may confirm the indication and type of surgical procedure, but this is not the subject of this article. Objective An overview of the current literature on pre-operative diagnostic principles is presented...

AIM: The main aims of the study were to examine whether human neonates' responses to communication disturbance modelled by the still-face paradigm were stable and whether their responses were affected by their previous experience with the still-face paradigm. METHODS: The still face procedure, as a laboratory model of interpersonal stress, was administered repeatedly, twice, to 84 neonates (0 to 4 day olds), with a delay of an average of 1.25 day. RESULTS: Frame-by-frame analysis of the frequency and duration of gaze, distressed face, crying, sleeping and sucking behaviours showed that the procedure was stressful to them both times, that is, the still face effect was stable after repeated administration and newborns consistently responded to such nonverbal violation of communication...

BACKGROUND: The vast majority of children around the world undergoing adenotonsillectomy for obstructive sleep apnea-hypopnea syndrome (OSA) are not objectively diagnosed with nocturnal polysomnography (NPSG) due to access availability and cost issues. Automated analysis of nocturnal oximetry (nSpO2), which is readily and globally available, could potentially provide a reliable and convenient diagnostic approach for pediatric OSA. METHODS: De-identified nSpO2 recordings from a total of 4,191 children originating from 13 pediatric sleep laboratories around the world were prospectively evaluated after developing and validating an automated neural network algorithm using an initial set of single-channel nSpO2 recordings from 589 patients referred for suspected OSA...

We assessed the validity of using a sheet-shaped body vibrometer (SBV) as a portable monitoring device for obstructive sleep apnea (OSA) screening. Seventy consecutive patients with suspected OSA underwent simultaneous in-laboratory polysomnography (PSG) and SBV. We evaluated the screening accuracy of the respiratory event index (REI) obtained with the SBV, using the REI based on either the estimated total sleep time (REI_eTST) or time in bed (REI_TIB); these were compared to the apnea-hypopnea index (AHI) obtained via PSG...
