Abstract
Background and Objectives: Sleep apnea involves repetitive cycles of obstructive sleep that disrupt sleep. This complication is the most important modifiable risk factors for stroke. The aim of this study was to assess sleep apnea in patients with stroke.
Material and Methods: In this cross-sectional study, 132 patients with stroke were recruited using convenience sampling. Data were gathered using the Berlin Questionnaire and were analyzed using descriptive and inferential statistical tests.
Results: The mean age of participants was 69/5 ± 11/6 years. The results showed that 54.5% of the patients were at high risk of sleep apnea. Moreover, there were significant differences between systolic (p=0.0001) and diastolic (p<0.01) blood pressures in high and low risk groups for sleep apnea.
Conclusion: Regarding the high prevalence of sleep apnea in patients with stroke and the relationship between sleep apnea with high blood pressure, it is recommended to use screening procedures to identify high risk patients.

Background and Objectives: Poor sleep quality is a common problem among patients with coronary artery bypass surgery. The aim of this study was to assess the effect of cardiac rehabilitation program on improving quality of sleep in patients with poor sleep quality after coronary bypass surgery.
Materials and Methods: This was a quasi-experimental study. From 88 patients referred to the cardiac rehabilitation clinic of Tehran Heart Center, 50 patients with poor sleep quality were recruited to the study. patients after complete demographic and sleep quality questionnaires, participated in an 8-weeks cardiac rehabilitation program including exercise training and life style education sessions. Participants were followed-up 4 weeks after the intervention. Data were analyzed in the SPSS-18 using statistical tests such as Paired t-test, Independent samples T test, and One-way ANOVA.
Results: After cardiac rehabilitation program, significant differences were shown in the sleep quality (p<0.001) and its dimensions including subjective sleep quality (p=0.024), sleep disturbances (p=0.002), using sleep medications (p<0.001), and day time dysfunction (p<0.001).
Conclusion: The findings showed that cardiac rehabilitation programs had positive effect on improving quality of sleep in patients after coronary artery bypass surgery.

Abstract
Background and Objectives: Difficult intubation is one of the challenges for patients undergoing anesthesia that leads to severe complications and death. Obstructive sleep apnea is one of the factors that may be associated with difficult intubation. The present study was carried out to investigate the relationship between obstructive sleep apnea and difficult intubation in the elderly.
Materials and Methods: This cross- sectional study was conducted in 2015 from February to June on 175 elderly patients using convenience sampling method. In order to gather data Demographic form, Berlin questionnaire and Comark-Lehane Index were used. Data were analyzed by SPSS (version 18) Statistical software and Kolmogorov-Smirnov, independent t-test, Mann-Whitney-u, chi-square tests and Logistic Regression.
Results: The mean age and SD of samples were 69.9±9.3 years. There were 18 (26.9%) people with difficult intubation and 10 (9.3%) people with normal intubation at high risk of sleep apnea. The results of this study showed that there was a significant relationship between sleep apnea and difficult intubation, and the risk of sleep apnea in the elderly with difficult intubation was 3.6 times of those with normal intubation (p=0.002, OR=3.6, CI 95%= 1.5-8.9).
Conclusion: There is a relationship between obstructive sleep apnea and difficult intubation in the elderly. Therefore, a screening procedure to identify the elderly at high risk of sleep apnea that are candidate for anesthesia seems to be necessary.

Abstract
Background: Autism is a developmental disorder that impairs social relationships. Sleep disorders are one of the major problems of patients with autism spectrum disorders (ASD).
Objectives: Concerning the need to investigate problems and impairments caused by this disease, the present study aimed at determining the effect of an eight-week endurance training program plus Q10 supplementation on sleep quality in children with ASD in 2017.
Methods: The present double-blind study was performed on three experimental groups. Group 1 performed eight-week endurance training on a one-mile distance as brisk walking. Group 2 received 100 mg Q10 supplements daily and Group 3 underwent a combination of both interventions. Pre- and post-tests were performed to determine the sleep habits of the study subjects using the children's sleep habits questionnaire (CSHQ) by parents. Finally, the pre- and post-tests data were compared using the paired samples t-test.
Results: A significant difference was observed between the pre- and post-test results in the mean total and eight subscales scores in the endurance training plus Q10 supplementation group (P <0.05). There was no significant difference between the pre- and post-test results in the sleep anxiety and sleep-disordered breathing subscales in the endurance training group and the sleep-disordered breathing subscale in the supplementation group.
Conclusion: According to the study results, it seems that the sleep of children with autism was improved by increased physical activity and Q10 supplementation.

Abstract
Background: Mothers in the postpartum period experiences a change in sleep pattern and loss of sleep duration. In the meantime, factors can cause irregular sleep patterns and decreased sleep quality.
Objectives: The aim of this study was investigating the factors of fertility, anxiety and physical activity on the sleep quality of the lactating women visiting healthcare centers in Zanjan, Iran.
Methods: This descriptive cross-sectional study was carried out from 2018 to 2019 on 380 women aged 14-45 years referred Ayatollah Mousavi Hospital in Zanjan and its affiliated clinics who were maximally 6 months postpartum and selected by convenience sampling method. The measuring tools used in this study included Petersburg Sleep Quality Questionnaire, Beck Anxiety Inventory, and a checklist containing demographic-fertility. Data were analyzed through SPSS software using descriptive and analytical tests (t-test, Mann-Whitney, and Chi-square). The statistical significance level was considered as p<0.05.
Results: in this study 45.8% (n= 174) of the participants suffered from mild anxiety and 13.2% (n= 50) of them from moderate anxiety. The mean score of their sleep quality was 4.70± 3.06. The effect of physical activity (p-value= 0.006) and anxiety level (p-value= 0.002) on women's sleep quality was statistically significant.
Conclusion: The results of the present study confirm the positive effect of regular physical activity and the negative effects of anxiety on sleep quality of the breastfeeding mothers.

Abstract
Background: Sleep disorders are common among hospitalized children. Aromatherapy is one of the interventions with demonstrated effectiveness in improving sleep quality.
Objectives: This study was conducted to investigate the effect of orange essential oil inhalation on the sleep quality of hospitalized children.
Methods: This semi-experimental study was conducted on 70 children admitted to Valiasr Hospital in Birjand selected by the convenience sampling method and then randomly assigned to two groups of orange essential oil receivers and the control group. In the intervention group, aromatherapy was performed every day for three days in three shifts (10 am, 4 pm, and at the usual bedtime). The researcher completed the BEARS sleep quality questionnaire at the beginning and end of the intervention period. Data analysis was conducted utilizing SPSS version 16 statistical software and chi-square, Mann-Whitney, paired t-test, McNemar, and t-test.
Results: There was no statistically significant difference in the demographic characteristics of the children in the two groups (p>0.05). The results showed no significant difference between the two study groups before the intervention regarding different sleep quality domains (p<0.05). After the intervention, there was a significant difference between the two studied groups in the domains of difficulty in falling asleep, waking up during the night, and disturbance in the regularity and duration of sleep (p<0.05), and the intervention group had better scores than the control group.
Conclusion: The present demonstrated that inhalation of orange essential oil had a favorable effect on the sleep quality of hospitalized children. This intervention can be introduced and implemented as an effective method to improve the sleep quality of hospitalized children.
