Background
Obstructive sleep apnea (OSA) is associated with increased oxidative stress. Certain essential trace minerals have shown to play an important role in the maintenance of redox homeostasis. We determined the concentrations of trace minerals in OSA patients and assessed their relationships to OSA severity as indicated by the apnea/hypopnea index (AHI).Methods
We enrolled 44 patients with newly diagnosed mild to moderate OSA and 20 without OSA. The following parameters were measured: polysomnographic values of nocturnal sleep; plasma trace minerals zinc (Zn), copper (Cu), iron (Fe), and erythrocyte selenium (Se); oxidative stress status; and plasma high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α).Results
Compared to controls matched for age, gender, and body mass index, OSA patients had lower concentrations of plasma Zn and erythrocyte Se and higher plasma concentrations of Cu and Fe. OSA patients had significantly higher plasma concentrations of hs-CRP, TNF-α, and malondialdehyde (MDA), and lower erythrocyte antioxidant enzyme glutathione peroxidase (GPx) and superoxide dismutase activities. Significant differences in all the above parameters were also found in patients with moderate OSA compared to those with mild OSA. Furthermore, AHI values correlated significantly with neck circumference, GPx activity, and MDA, hs-CRP, and TNF-α concentrations in OSA patients. AHI values were also negatively associated with concentrations of plasma Zn and erythrocyte Se, but were positively linked to plasma concentrations of Fe and Cu.Conclusions
Abnormal concentrations of these trace minerals may reflect oxidative damage and inflammatory response, thus increasing the severity of OSA. 相似文献2.

Purpose
Sleep problems are very common in people with diabetes. The aim of this study was to assess the association of the combination of self-reported sleep duration and sleep quality on quality of life (QOL) in Chinese patients with type 2 diabetes mellitus (T2DM).Methods
We analyzed the community-based cross-sectional data of 798 patients with T2DM in Xiamen, China, in 2016. Sleep duration was measured as self-reported average sleep time during the previous month. Sleep quality was evaluated as self-rated reports. QOL was assessed by the Diabetes-specific Quality of Life (DSQL), with scores?<?40 and ≥?80 set as cut-off values for differentiating good, fair, and poor QOL. Ordinal logistic regression was performed to model the associations of QOL with sleep duration, sleep quality, and their combined effects by adjusting for certain covariates.Results
The separate associations of sleep duration and sleep quality in relation to QOL in T2DM patients were significant (P?<?0.05). After controlling for sleep quality, there was no significant correlation between sleep duration and QOL. The combined analysis suggested that the association of sleep duration with QOL in T2DM patients was sleep quality-dependent. Longer sleep duration was associated with higher odds ratios (ORs) of better QOL for patients who reported fair sleep quality and good sleep quality, but no such trend was observed for patients who reported poor sleep quality (P> 0.05). Excessive sleep duration (≥?9 h per day) was detrimental to QOL in T2DM only when they reported poor sleep quality.Conclusions
Specific disparities exist in the association of sleep quality with sleep duration and QOL in T2DM patients. Failures to take into account the effect of sleep quality when evaluating the impact of sleep on QOL significantly bias the results. It is important to integrate duration and quality of sleep as a composite sleep index when assessing sleep of patients with T2DM.3.

Purpose
Obstructive sleep apnea (OSA) can lead to severe health consequences. Drivers of motor vehicles with untreated or undiagnosed OSA have a greater risk of traffic accidents. Use of self-reported questionnaires is the first step in OSA diagnosis. The main aim of this study was to perform the translation and validation of Berlin Questionnaire in a sample of commercial drivers.Methods
After formal translation, validation was performed on a sample of commercial drivers and included evaluation of internal consistency, test–retest reliability, construct and criterion validity. Full-night attended polysomnography or cardiorespiratory polygraphy was used for OSA diagnosis.Results
One hundred male participants, 24–62 years old, were included. Berlin Questionnaire classified 35 % subjects as potential OSA patients. Polysomnography confirmed OSA in 58 % of the subjects. Berlin Questionnaire showed good internal consistency (Cronbach’s alpha 0.82—first category, 0.73–0.95—second category). Test–retest reliability (Cohen’s kappa 0.78) was adequate. Berlin score was significantly correlated with OSA category and apnea–hypopnea index (AHI). Sensitivity of Berlin Questionnaire was from 50.9 (AHI ≥ 5) to 75 % (AHI ≥ 30), while specificity ranged from 86 to 70.5 %.Conclusions
Berlin Questionnaire (Serbian version) showed good measurement properties, creating basis for further research of its usefulness as OSA screening tool in populations of interest.5.

Background
With the increase of pediatric cancer survival rates, late effects and quality of life (QoL) have received more attention. Disturbed sleep in pediatric cancer is a common clinical observation, but research on this subject is sparse. In general, sleep problems can lead to significant morbidity and are associated with impaired QoL. Information on sleep is essential to develop interventions to improve QoL. 相似文献6.

Background
The longer-term health impacts of poor sleep quality are of increasing interest, as evidence suggests that there are rising levels of sleep disturbance in the community. Studies have reported links between sleep quality and increased morbidity and mortality. However, the results of these studies are constrained by limitations in the measurement of sleep quality in epidemiologic studies. The Breast Cancer Environment and Employment Study (BCEES) has developed a sleep questionnaire that attempts to address some of the limitations of previous sleep questionnaires. The present study assessed the test-retest reliability of the sleep questionnaire used in the Breast Cancer Environment and Employment Study (BCEES).Methods
Subjects for this reliability study were women who were participating as controls in the BCEES study. Test-retest reliability was evaluated for individual items, using weighted kappa for categorical variables and intraclass correlation coefficients (ICC) and limits of agreement for continuous variables.Results
Most sleep questions showed good agreement, ranging from 0.78 to 0.45. The ICC was 0.45 (95% CI 0.32–0.59) for lifetime sleep loss per year and 0.60 (95% CI 0.49–0.71) for symptom severity.Conclusions
The test-retest reliability of the general sleep questions was good, and future epidemiologic studies of sleep could reliably expand the number of assessed domains of sleep quality. However, reliability decreased as increasing detail was required from participants about specific periods of sleep disturbance, and changes to the questionnaire are warranted.Key words: sleep quality, sleep duration, questionnaire, reliability, test-retest, epidemiology 相似文献8.

OBJECTIVE
To analyze the association between sleep quality and quality of life of nursing professionals according to their work schedules.METHODS
A prospective, cross-sectional, observational study was conducted between January and December 2010, with 264 nursing professionals, drawn from 989 subjects at Botucatu General Hospital and stratified by professional category. The Pittsburg Sleep Quality Index and the WHOQOL-bref were administered to evaluate sleep quality and quality of life, respectively. Self-reported demographic data were collected with a standard form. Continuous variables were reported as means and standard deviations, and categorical variables were expressed as proportions. Associations were evaluated using Spearman’s correlation coefficient. The association of night-shift work and gender with sleep disturbance was evaluated by logistic regression analysis using a model adjusted for age and considering sleep disturbance the dependent variable. The level of significance was p < 0.05.RESULTS
Night-shift work was associated with severe worsening of at least one component of sleep quality in the model adjusted for age (OR = 1.91; 95%CI 1.04;3.50; p = 0.036). Female gender was associated with sleep disturbance (OR = 3.40; 95%CI 1.37;8.40; p = 0.008). Quality of life and quality of sleep were closely correlated (R = -0.56; p < 0.001).CONCLUSIONS
Characteristics of the nursing profession affect sleep quality and quality of life, and these two variables are associated. 相似文献12.
Purpose
To evaluate the impact of nocturnal calf cramping (a condition that affects one in two people over 60 years of age) on quality of sleep and health-related quality of life.Methods
Eighty adults who experienced nocturnal calf cramp at least once per week and eighty age- and sex-matched controls who never experienced nocturnal cramp were recruited from the Greater Newcastle and Central Coast regions of New South Wales, Australia. All participants completed the SF-36v2 and the Medical Outcomes Study Sleep Survey (MOS-SS).Results
People who experienced nocturnal muscle cramps reported more sleep disturbance (p < 0.001), less adequate sleep (p = 0.001), less quantity of sleep (p = 0.02) and more snoring (p = 0.03). Both sleep problem summary indices for the MOS-SS identified people who experienced nocturnal muscle cramp as having more sleep problems than the controls. People who experienced nocturnal muscle cramps had lower health-related quality of life for the SF-36 domains role physical (p = 0.007), bodily pain (p = 0.003) and general health (p = 0.02). SF-36 domains that primarily relate to mental health were not significantly different between groups. The impact of nocturnal calf cramps on health-related quality of life was largely explained by their negative impact on quality of sleep.Conclusions
Nocturnal calf muscle cramps are associated with substantially reduced quality of sleep and reduced physical aspects of health-related quality of life. 相似文献13.

Background
Sleep quality has been widely studied among western countries. However, there is limited population-based evidence on insomnia in Chinese adult populations, especially in middle-aged and older adults. The aims of present study are to (1) examine the prevalence of poor sleep among Chinese middle-age and older adults, (2) compare the Pittsburgh Sleep Quality Index (PSQI) seven domain scores across different physical health statuses, (3) explore factors associated with insomnia.Methods
A cross-sectional survey was conducted using a multi-instrument questionnaire. In total, 1563 residents aged 45 or older in the community were interviewed. The Chinese version of the PSQI was used to assess sleep quality while poor sleep was defined as a total PSQI score >5. Socio-demographic, lifestyle and physical health data were also collected.Results
The prevalence of poor sleep among adults aged over 45 years was 20.67 %. Clusters logistic regression analysis identified that migrant workers, single marital status, lower education level, no physical exercise, illness within 2 weeks, and a higher total number of chronic diseases contribute to increased risk of poor sleep (P < 0.05). Among three clusters, physical health has the biggest independent contribution on sleep quality.Conclusions
Our results indicated that poor sleep was common in middle-aged and older adults. It was associated with identity of migrant worker, education level, exercise, illness within 2 weeks and number of chronic disease. Being ill within 2 weeks and having more chronic diseases were the major physical health-related factors contributing to poor sleep in the middle-aged and older people. Physical health may be a major determinant in sleep quality.14.
Background
Although considerable progress has been made in the treatment of chronic kidney disease, compromised quality of life continues to be a significant problem for patients receiving hemodialysis (HD). However, in spite of the high prevalence of sleep complaints and disorders in this population, the relationship between these problems and quality of life remains to be well characterized. Thus, we studied a sample of stable HD patients to explore relationships between quality of life and both subjective and objective measures of nocturnal sleep and daytime sleepiness 相似文献15.
Background
Hospitalization can significantly disrupt sleeping patterns. In consideration of the previous reports of insomnia and apparent widespread use of benzodiazepines and other hypnotics in hospitalized patients, we conducted a study to assess quality of sleep and hypnotic drug use in our acute care adult patient population. The primary objectives of this study were to assess sleep disturbance and its determinants including the use of drugs with sedating properties. 相似文献16.

Objective
In the present work, we evaluated the effect of the intake of a Jerte Valley cherry-based product (JVCP), compared to a placebo product, on sleep quality, urinary 6-sulfatoxymelatonin (aMT6-s) levels and the serum concentration of interleukin-1β (IL-1β), tumor necrosis factor α (TNF-α) and interleukin-8 (IL-8).Design
This was a blind, placebo-controlled, randomized, crossover study.Setting
University of Extremadura (Spain).Participants
Ten young (20–30 years old), ten middle-aged (35–55 years old), and ten elderly (65–85 years old) participants.Intervention
A placebo (Kool-Aid®) or JVCP (patent no. ES 2342141 B1) were consumed twice a day, as lunch and dinner desserts.Measurements
Actigraphic monitoring was used to record and display the temporal patterns of the individuals’ activity and rest. Urinary aMT6-s and serum cytokines (IL-1β, TNF-α and IL-8) were also determined.Results
The consumption of the JVCP improved the nocturnal rest, measured by sleep efficiency, number of awakenings, total nocturnal activity, sleep latency, assumed sleep, actual sleep time and immobility. Moreover, it was detected an increase in both the levels of aMT6-s found in first-void morning urine and the concentrations of serum pro-somnogenic cytokines obtained from samples collected at the acrophase of the melatonin rhythm (1.00 am) in all experimental age groups after the JVCP consumption. Generally, better results were obtained with advancing age.Conclusion
The ingestion of the JVCP may contribute to establish a high-quality sleep and be used as a potential nutraceutical tool to prevent sleep disorders with the advance of age. 相似文献18.

Background
Sleep disturbances are common in individuals with Multiple Sclerosis (MS), but the impact of poor sleep quality on cognitive and physical function in individuals with MS is less clear.Objective/Hypothesis: The purpose of this study was to examine the relationship between sleep quality and cognitive and physical function in individuals with mild MS.Methods
Forty individuals with relapsing-remitting or secondary-progressive MS (50.3 ± 11.6 years of age) participated. The Pittsburgh Sleep Quality Index (PSQI) was used to index sleep quality. A PSQI of ≤5 was considered good sleep quality and >5 was considered poor sleep quality. Cognitive function was assessed using a battery of cognitive tests, and physical function was assessed using 2 objective measures and a self-report measure.Results
Thirteen individuals (32.5%) indicated good sleep quality and 27 (67.5%) of the participants reported poor sleep quality. Those with good sleep quality performed significantly better on a visuospatial memory test (p = 0.025) and reported higher functional abilities (p < 0.001) compared to those with poor sleep quality. There was no difference in performance on the cognitive tests of verbal memory, information processing, or executive function, or the objective function measures. Individuals with poor sleep quality had higher levels of fatigue, depression, and anxiety, and lower quality of life.Conclusions
Visuospatial memory appears to be the memory domain particularly associated with poor sleep quality in people with mild MS. Also, individuals with mild MS with poor sleep quality may underestimate their functional abilities. 相似文献19.

Background
Disturbed sleep is commonly reported in fibromyalgia (FM). Both the Sleep Quality Numeric Rating Scale (NRS) and the Medical Outcomes Study Sleep Scale (MOS-Sleep) have demonstrated positive psychometric properties in patients with FM. However, these assessments were developed prior to the current recommendation to include patient input during the concept elicitation or item generation phases. Therefore, the objective of this study was to evaluate the impact of FM on participants, including their sleep, and to test the content validity of these two sleep measures in FM patients. 相似文献20.
