The effect of continuous positive airway pressure therapy on nasal patency.

Nasal congestion and obstruction are reported in the majority of continuous positive airway pressure (CPAP) users and are frequently cited as reasons for noncompliance. To our knowledge, no study has demonstrated a change in objective or subjective nasal patency in patients with obstructive sleep apnea (OSA) after a therapeutic trial of CPAP therapy.

Is subjective sleep evaluation a good predictor for obstructive sleep apnea?

To compare subjective sleep evaluation obtained using four questionnaires with polysomnography results for individuals with and without obstructive sleep apnea.

Measuring Sleep in Vulnerable Older Adults: A Comparison of Subjective and Objective Sleep Measures.

This study compared subjective (questionnaire) and objective (actigraphy) sleep assessments, and examined agreement between these methods, in vulnerable older adults participating in a Veterans Administration Adult Day Health Care (ADHC) program.

Premenstrual syndrome and sleep disturbances: Results from the Sao Paulo Epidemiologic Sleep Study.

The aim of this study is to compare sleep characteristics between women with premenstrual syndrome (PMS) and a control group. The data were extracted from an epidemiologic survey conducted in Sao Paulo (EPISONO), Brazil, which used subjective assessments and objective polysomnography records to analyze subjects' sleep pattern. Subjective questionnaires used in this study were Women's Questionnaire, Pittsburgh Sleep Quality Index, Epworth sleepiness scale, Insomnia Severity Index and the general sleep questi...

Detecting inspiratory flow limitation with temporal features of nasal airflow.

Inspiratory flow limitation is a breathing pattern during sleep caused by upper airway (UA) narrowing that occurs during snoring and various degrees of obstructive sleep apnea (OSA). Clinical examination of flow limitation relies on identifying patterns of airflow contour, however this process is subjective and lacks physiological evidence of UA narrowing. Our objective is to derive the temporal features of nasal airflow contour that characterize flow limitation. The features that correlate with UA narrowin...

The Neurophysiological Basis of the Discrepancy between Objective and Subjective Sleep during the Sleep Onset Period: an EEG-fMRI study.

Subjective perception of sleep is not necessarily consistent with EEG indications of sleep. The mismatch between subjective reports and objective measures is often referred to as "sleep state misperception" (SSM). Previous studies evince that this mismatch is found in both insomnia patients and in normal sleepers, but the neurophysiological mechanism remains unclear. The aim of the study is to explore the neurophysiological basis of this mechanism, from the perspective of both EEG power and fMRI fluctuation...

Sleep profile in anorexia and bulimia nervosa female patients.

Sleep wake cycle and eating patterns undergo major changes throughout life and have been proved to be very correlated. Eating disorder prevalence is increasing and sleep problems are very common among them. The current study is concerned with investigating the sleep pattern in anorexia and bulimia female patients using both subjective and objective assessment tools.

Subjective and objective sleep discrepancy in symptomatic bipolar disorder compared to healthy controls.

Bipolar disorder (BD) is associated with sleep misperception. The objective of this study was to investigate the correlation between subjective and objective measures of sleep in persons with symptomatic bipolar disorder (BDS) compared to healthy controls (HC).

Mask pressure effects on the nasal bridge during short-term noninvasive ventilation.

The aim of this study was to assess the influence of different masks, ventilator settings and body positions on the pressure exerted on the nasal bridge by the mask and subjective comfort during noninvasive ventilation (NIV). We measured the pressure over the nasal bridge in 20 healthy participants receiving NIV four different NIV masks (three oronasal masks, one nasal mask) at three different ventilator settings and in the seated or supine position. Objective pressure measurements were obtained with an I-...

Correlates of disrupted sleep-wake variables in patients with advanced cancer.

High rates of sleep difficulties have been found in patients with advanced cancer. However, not much is known about factors that are associated with sleep impairments in this population and that could constitute their potential risk factors or consequences. This study conducted in patients with cancer receiving palliative care aimed to evaluate the relationships of subjective (sleep diary; Insomnia Severity Index, ISI) and objective (actigraphy) sleep-wake variables with several physical and psychological s...

Severe Obstructive Sleep Apnea is Associated with Alterations in the Nasal Microbiome and Increase in Inflammation.

Obstructive Sleep Apnea (OSA) is associated with recurrent obstruction, sub-epithelial edema, and airway inflammation. The resultant inflammation may influence or be influenced by the nasal microbiome.

Bright environmental light ameliorates deficient subjective liking in insomnia: an experience sampling study.

Altered comfort sensing and reduced gray matter volume in the orbitofrontal cortex of the brain in people suffering from Insomnia Disorder (ID) suggest compromised processes of motivation and hedonia. The Experience Sampling (ES) method was used to evaluate whether, in naturalistic conditions, people with ID differ from those without sleep complaints with respect to subjective wanting and liking, two major dimensions of the reward system. Since light affects brain circuits involved in affect and reward, ES ...

Pediatric Nasal Traumas: Contribution of Epidemiological Features to Detect the Distinction Between Nasal Fractures and Nasal Soft Tissue Injuries.

Nasal bone is prone to injury due of its prominent position on the face. Epidemiologic surveys are necessary to investigate nasal traumas. The aim of the present study is to examine the distribution of trauma etiologies according to age, sex, and seasonality in pediatric patients who present with nasal trauma, and to classify the pathologies according to their etiology as nasal fractures or nasal soft tissue injuries.

A Preliminary Study of Central Nervous System Arousal and Sleep Quality in Bipolar Disorder.

Sleep disturbances are commonly reported in patients with bipolar I disorder (BPI) and are risk factors for mood episodes. In other populations, central nervous system (CNS) hyperarousal is associated with sleep initiation and maintenance problems, and CNS hypoarousal is associated with increased sleep drive. However, it is unclear whether CNS arousal levels are a useful index of sleep disruption in BPI. This study aimed to investigate daytime CNS arousal levels in relation to perceived sleep quality in BPI...

Sleep: Eye-Opener Highlights Sleep's Organization.

What can eyes tell us about what happens during sleep? Their movements split sleep into two distinct states - rapid-eye-movement (REM) or non-REM sleep. A new study now reveals that periodic pupil constrictions are linked to non-REM sleep plunging into deeper offline states and back about every minute.

Subjective sleep quality, blood pressure, and hypertension: a meta-analysis.

Sleep quality is an important aspect of sleep, but no meta-analysis has elucidated its relationship with blood pressure (BP) and hypertension. A meta-analysis was conducted in October 2016 using multiple databases, including Embase and Medline. Studies that assessed subjective sleep quality and BP or hypertension were included. Upon full-text evaluation, 29 articles from 45 041 patients were selected, of which 22 articles were included in the meta-analysis and seven were presented narratively. Poor sleep q...

The role of sleep in emotional memory processing in middle age.

Sleep benefits memory in young adults, and this effect may be particularly strong for representations associated with negative emotion. Many aspects of sleep important for memory consolidation change with aging, particularly by middle age, suggesting that sleep-related consolidation may be reduced. However, the influence of sleep on memory has rarely been investigated in a middle-aged population. In the current study, young and middle-aged adults viewed negative and neutral pictures and underwent a recognit...

Impact of shift work schedules on actigraphy-based measures of sleep in Hispanic workers: Results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) ancillary Sueño study.

To describe sleep characteristics of shift workers compared to day workers from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sueño ancillary study, and test the hypothesis that shift work is associated with shorter sleep duration, worse sleep quality, greater sleep variability and other sleep/health related factors.

Symptoms of Obstructive Sleep Apnea, Nasal Obstruction, and Enuresis in Children With Nonsyndromic Cleft Lip and Palate: A Prevalence Study.

To estimate the prevalence of symptoms of obstructive sleep apnea (OSA), nasal obstruction, and enuresis in children with nonsyndromic unilateral cleft lip and palate.

Any sleep is a dream far away: a nominal group study assessing how gout affects sleep.

There are no qualitative studies of sleep in gout; the aim of this study was to examine the impact of gout on sleep.

The Nasal Ligaments and Tip Support in Rhinoplasty: An Anatomical Study.

In 1971, Janeke and Wright1 published a now classic study on the support of the nasal tip in which they found four areas of anatomic support. These findings led to the "tripod concept" of tip support. Recently, surgeons have begun repairing and/or preserving the nasal ligaments as a method to control tip projection and rotation. Therefore, a reassessment of the nasal ligaments and tip support is warranted.

The Acute Effects of Intermittent Light Exposure in the Evening on Alertness and Subsequent Sleep Architecture.

Exposure to bright light is typically intermittent in our daily life. However, the acute effects of intermittent light on alertness and sleep have seldom been explored. To investigate this issue, we employed within-subject design and compared the effects of three light conditions: intermittent bright light (30-min pulse of blue-enriched bright light (~1000 lux, ~6000 K) alternating with 30-min dim normal light (~5 lux, ~3600 K) three times); continuous bright light; and continuous dim light on subjective an...

Effects of Bilateral Nasal Packing on Oxygen Saturation and Blood Pressure.

Nasal packing is one of the most common rhinological procedures in ENT practice exerting local in nose and systemic effects. Systemic effects may be due to poor sleep quality, respiratory difficulty, decreased oxygen saturation, circulatory problems and toxic shock syndrome which can threaten the life of a person.The study was done to investigate the effect on bilateral nasal packing on blood oxygen saturation and blood pressure changes.

Effect of Diabetes Sleep Education for T2DM Who Sleep After Midnight: A Pilot Study from China.

Our prior study showed that patients with sleep disorders had poor blood pressure (BP), glycemic control, and more severe complications. Therefore, sleep is very important for diabetic control. Our work was to investigate whether individualized diabetes sleep education significantly improve sleep quality and glycemic control in type 2 diabetic patients who sleep after midnight and potential mechanism by a randomized parallel interventional study.

Analysis of nocturnal hypokinesia and sleep quality in Parkinson's disease.

Nocturnal hypokinesia/akinesia and sleep disorder are believed to be common in Parkinson's disease (PD), but are often underestimated. To date, only a few studies have focused on nocturnal symptoms related to motor function and sleep quality in PD patients, and the assessments were based mainly on the subjective descriptions of the patients. In this study, we assessed the relationships between motor symptoms and sleep quality in 29 PD patients (17 PD patients reporting impaired bed mobility (IBM) and 12 pat...
