Many studies have indicated associations between impaired nasal breathing and sleep disorders. However, the precise nature of the relationship between nasal patency and sleep remains unclear.

Effects of subjective sleep quality on the quality of life in patients with chronic anorectal disorder.

The aim of the present study was to evaluate the subjective sleep quality in patients with anorectal disorder, to determine the factors associated with subjective sleep quality, and to explore the relationship between subjective sleep quality and quality of life.

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.

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.

Could Nasal Surgery Affect Multilevel Surgery Results for Obstructive Sleep Apnea?

To study the role of nasal surgery as a part of multilevel surgery for management of obstructive sleep apnea (OSA).

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.

Reciprocal associations between daily need-based experiences, energy, and sleep in chronic fatigue syndrome.

Previous findings indicate that patients with chronic fatigue syndrome (CFS) report significant day-to-day fluctuations in subjective energy and sleep. Herein, we examined whether daily variation in the satisfaction and frustration of the basic psychological needs for autonomy, competence, and relatedness would contribute to daily variation in subjective energy and quality and quantity of sleep. In addition, we examined whether daily variation in sleep would contribute to daily need-based experiences throug...

Correlation Between the Existing Classifications of Nasal Bone Fractures and Subjective Patient Satisfaction.

Since the nose is at the center of the face, small changes to it can cause a big overall change. Therefore, a nasal fracture needs to be operated on when deformity is expected. Although many taxonomies have been developed for nasal bone fractures, no study has aimed to predict individual patient satisfaction. Herein, the authors tried to determine any correlation between the existing classifications of nasal bone fractures and subjective patient satisfaction. A retrospective study and telephone survey were ...

Pharmacological agents for improving sleep quality at high altitude: a systematic review and meta-analysis of randomized controlled trials.

Several hypnotic agents commonly recommended for improving sleep at sea level are discouraged at high altitude. We aimed to evaluate the efficacy and safety of drugs prescribed for improving sleep quality in patients with acute exposure to high altitudes by conducting a systematic review and meta-analysis. An electronic search was executed for randomized controlled trials comparing drug treatments with placebo and no-treatment conditions, which used objective sleep parameters or subjective sleep quality eva...

Melatonin and cortisol in individuals with spinal cord injury.

The aim of this study was to investigate circadian rhythm and sleep complaints in individuals with spinal cord injury (SCI) as determined by diurnal saliva melatonin and cortisol as well as activity measurements and subjective sleep quality.

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...

The internal nasal valve: a validated grading system and operative guide.

Nasal obstruction is a highly subjective and commonly reported symptom. The internal nasal valve (INV) is the rate limiting step to nasal airflow. A static INV grading score was devised with regard to visibility of the middle turbinate.

The efficacy of nasal airway stent (Nastent) on obstructive sleep apnea and prediction of treatment outcomes.

Obstructive sleep apnea (OSA) is characterized by recurrent episodes of partial or complete upper airway collapse during sleep and is highly prevalent in the general population. The nasopharyngeal airway stent (Nastent) is a specifically designed, preformed silicone tube that intends to maintain the upper airway patency during sleep and reduce snoring and sleep apnea.

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...

Sleep duration, health status, and subjective well-being: a population-based study.

To evaluate, in a population-based approach, the association of extreme sleep duration with sociodemographic factors, health, and well-being.

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.

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

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...
