Abstract Introduction The rapid growth of point-of-care polysomnographic alternatives has necessitated standardized evaluation and validation frameworks. current average across participant methods may overestimate the agreement between wearable sleep tracker devices polysomnography (PSG) systems because high base rate during night interindividual difference sampling population. Methods This stu...

Using one-night sleep recordings from 852 subjects all living in Uppsala, Sweden, the present study represents one of largest polysomnography investigations into association 29.53-day long lunar cycle with among men and women across a wide age range (22–81 years). Following day after new moon until full (also named waxing period), moon's illumination increases, timing meridian is gradually shif...

Background: Overweight and obesity are major public-health issues in Mexico. Sleep breathing disorders directly impact the health of affected subjects. The aim of this study was to describe the frequency and severity of obstructive sleep apnea/hypopnea syndrome (OSAHS) in Mexican adolescents grouped by weight status. Secondary objectives were to describe the influence of body mass index (BMI) a...

OBJECTIVE To determine if sleep talkers with REM sleep behavior disorder (RBD) would utter during REM sleep sentences learned before sleep, and to evaluate their verbal memory consolidation during sleep. METHODS Eighteen patients with RBD and 10 controls performed two verbal memory tasks (16 words from the Free and Cued Selective Reminding Test and a 220-263 word long modified Story Recall Te...

To estimate reliability of self-reported compliance with nasal continuous positive airway pressure (CPAP) therapy for obstructive sleep apnea (OSA), we studied 63 OSA patients aged 53.7 +/- 1.2 years (mean +/- SEM) with an apnea hypopnea index (AHI) of 50.8 +/- 2.9 and lowest sleep SaO2 of 65.6 +/- 2.3 percent receiving nasal CPAP for 539 +/- 44 days. During a follow-up polysomnography (PSG) on...

We evaluated an auto-nasal continuous positive airway pressure (nCPAP) prototype (MC+; SEFAM, Nancy, France) in which apnoea/hypopnoea detection was disabled and nasal mask pressure vibration detection was the only mode of pressure setting. The device was tested in 15 previously untreated obstructive sleep apnoea patients during a night with polysomnography. We observed that a single night of a...

BACKGROUND Poor sleep is common in intensive care unit (ICU) patients, where environmental factors contribute to reduce and fragment sleep. The objective of this study was to evaluate the impact of earplugs and eye mask on sleep architecture in ICU patients. METHODS A single-center randomized controlled trial of 64 ICU patients was conducted from July 2012 to December 2013. Patients were rand...

BACKGROUND Most split-night sleep (SNS) studies have enrolled Caucasian patients with moderate-to-severe obstructive sleep apnea-hypopnea syndrome (OSAHS), with different apnea-hypopnea index (AHI) criteria for diagnosis and successful CPAP titration from the standard full-night study (FNS). This study aimed to describe a shortened diagnostic SNS in the Taiwanese population using diagnostic and...

STUDY OBJECTIVE Determine the utility of nocturnal oximetry as a screening tool for sleep apnea-hypopnea syndrome (SAHS) compared with polysomnography (PSG). DESIGN Cost-effectiveness analysis based on retrospective review of overnight sleep studies. SETTING United States Air Force tertiary teaching hospital. PATIENTS One hundred consecutive patients evaluated for SAHS by overnight sleep ...
