Volume 66, Issue 1 (3-2008)
Abstract

Background: Sleep has a major role in daily cycles and reconstruction of physical and mental abilities. Regarding the importance of this feature, we decided to determine sleep quality in medical students.

Methods: A questionnaire containing demographic data, Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index was prepared. We distributed the questionnaires using a census method to every student at the Zanjan Faculty of Medicine. The completed questionnaires were collected and the data was analyzed using SPSS.

Results: A total of 224 students answered the questionnaire, with 133 (59.4%) students evaluated to have good sleep quality and 91 (40.6%) poor sleep quality. Of these 91 students, 38% were female and 44.8% were male (p=0.307). The prevalence of poor sleep quality according to the four stages of medical training was 24.6% of those in basic sciences, 42.9% of those in physiopathology, 41.7% of externs, and 53.5% of interns (p=0.008). According to residential status, the prevalence of poor sleep quality was 61.5% among students living with their spouse, 44.6% for students living in their own private homes, 37.6% among students living in the dormitory, and 20.8% for those living with their parents (p=0.024). According to marital status, 35.8% of singles and 64.9% of married students had poor sleep quality (p=0.001). According to financial status, 57.9%, 46.9%, and 33.9% of those from low, moderate and high economic classes, respectively, were sleep deprived (p=0.049). Among those with average grades of under 16 and over 16 out of 20, 47.5% and 32%, respectively, were suffering from poor sleep quality (p=0.047). There was no obvious relationship between sleep quality and BMI, sex, or history of depression or anxiety.

Conclusion: Poor sleep quality was significantly associated with lower grades, economic status, living arrangement and type of training. A large number of students quality of life and work may suffer because sleep deprivation.

Abstract

Normal 0 false false false EN-GB X-NONE AR-SA MicrosoftInternetExplorer4 Background: Mood disturbances, such as anxiety, depression and psychological distress, are common among women in menopausal period. Effect of long term estrogen replacement on post menopausal  mood disturbances is curative but specifical studies has not done on the effects of vaginal hormonal therapy in mood disturbances in menopause. The aim of this study was objectives to clarify the effect extended by Hormon Replacement Therapy (HRT) in improving post menopausal mood disturbances.
Methods: In a single blinded clinical trial, the effects of a four months application of vaginal esterogen (premarin) versus placebo (n=20) in each groups were evaluated on mood status and sexual satisfaction, using the Hamilton depression score (HDS score), and self assessment of sexual function and pleasure. Four months after treatment completion (half applicator of nightly vaginal premarin or lubricant vaginally) collected and analyzed with Statistical tests.
Results: Decline of the mean HDS scores (depression score) was observed in the premarin group. The mean HDS score (depression) after vaginal premarin decreased from (14.6±4.7) to (3.4±2.3). (p≤0.001) also, The HDS score in placebo group increased from (10.6±3.1) to (11±3.3), that significant difference between two groups before and after treatment is seen. (p≤0.01). Vaginal premarin induced a greater improvement of HDS score (p≤0.006). Mean anxiety score decreased after vaginal premarin (p≤0.000), but is not significant difference in placebo group. (p=0.08). Sexual Satisfaction in Vaginal premarin group is significantly higher (p≤0.001).
Conclusions: Vaginal Estrogene directly or indirectly improved menopausal related mood and sleep disturbances, increased and sexual satisfaction.

Volume 69, Issue 8 (11-2011)
Abstract

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background: Sleep and sleep deprivation plays a major role in EEG abnormalities and also idiopathic and symptomatic seizures. The aims of this study were to compare baseline EEG findings with waking and sleep EEGs after sleep deprivation in patients with sleep seizure.
Methods : In this cross-sectional study, 33 patients with sleep seizure attending the Neurology Clinic of Sina Hospital in Tehran, Iran, during year 2009 were enrolled. After a baseline EEG, patients were asked to remain awake for 24 hours before taking a waking and a sleep EEG. Finally, the baseline EEGs were compared with findings from waking and sleep EEGs after sleep deprivation.
Results : From 33 patients with sleep seizure, sixteen (48.5%) patients were female and seventeen (51.5%) were male. Patients aged from 7 to 49 years and the mean age of the participants was 26.83 (SD=10.69) years. Twenty patients had no family histories of seizure contrary to 13 patients with a positive history for the disease. There was statistically significant differences between the baseline and waking EEGs after sleep deprivation (P=0.042) as there was between baseline and sleep EEGs (P=0.041). Moreover, there was significant differences between waking and sleep EEGs after sleep deprivation (P=0.048).
Conclusion: This study demonstrated the effects of sleep deprivation on EEG findings in patients with sleep seizure. In patients with sleep seizure, waking and sleep EEGs could be better demonstrated after sleep deprivation than routine waking EEGs. According to the results of this study, waking EEGs taken after a period of sleep deprivation is superior to sleep EEGs after the deprivation.

Volume 73, Issue 1 (4-2015)
Abstract
Enuresis is the inability to control urination during sleep. It is one of the most common childhood urologic disorders. Nocturnal enuresis refers to the occurrence of involuntary voiding at night after 5 years. Persistent nocturia can decrease self-esteem, increase anxiety and other emotional problems in children. The aim of this study is to evaluate the factors affecting nocturia amongst school-aged children. Methods: This cross- sectional study was conducted on 200 children over a period of 3 months from 21 April to 22 July 2014 (. Subjects of this study included 200 children (100 boy and 100 girl) aged 6 to 12 years that referred to the urology clinic. Following the written consent, patients under study were divided into two groups according to gender. A questionnaire concerning the personal data was completed for each patient. Questionnaires were completed by interviewing parents. Results: Our investigation revealed that 32% of children had nocturnal enuresis. The Chi-square test demonstrated significant differences between the case and control groups in terms of gender (P= 0.002), positive family history (P= 0.004), deep sleep (P= 0.005) and high fluid intake (P= 0.00). Significant differences were not observed among enuretic children with parents' education level, income, number of family members, birth order, history of injury and hospitalization, birth of a new baby, moving house, problems at school and home, snoring, mouth breathing, urinary tract infections, constipation (P> 0.05). Conclusion: In order to control enuresis it seems essential to provide information about nocturia and its etiologic factors to the children and their parents by the physician.

Abstract

Background: Different treatment used for resolving menopausal problems. Some studies assayed effectiveness of citalopram but it had some side effects and other studies about medicinal plants in Iran, including Melissa (combination of officinalis and foeniculum vulgare) showed improvement insomnia and anxiety. This study decided to assay effectiveness of this drug and comparison with placebo and citalopram in treatment of sleep disturbance of menopausal women.

Methods: Sixty postmenopausal women suffering from sleep disturbances that referred to Yas hospital between 2011-2013 were recruited to this double blind controlled study with 8 weeks’ follow-up period. They were randomized in three groups of twenty patients each, group A: received Melissa 600 mg that made by traditional medical school, group B: received citalopram 20 mg from Arya company that increased to 30 mg after one week and group C: received placebo. The patients were evaluated by Pittsburgh Sleep Quality Index (PSQI) questionnaire before and after treatment, also we checked the side effects of every drugs. Study was dissertation of one of the author with code 22263. This research has been supported by Tehran University of Medical Sciences and Health Services Grant. This study was registered at Iranian Registry of Clinical Trials with code of IRCT2013072714174N1.

Results: Pittsburgh sleep quality index improved significantly in all groups, there was significant differences between Melissa group and two other group, but there wasn’t significance difference between citalopram and placebo group, there was a trend in favor of Melissa versus citalopram and placebo. All of seven field of PSQI improved significantly in all groups that showed improvement of sleep quality in all field of sleep disturbance.

Conclusion: Melissa (compound of officinalis and foeniculum vulgare) may be recommended for the treatment of sleep disturbances in postmenopausal women. Although further investigation with more cases is needed to find long-term results and compare with hormone therapy.

Abstract
Background: Sleep quality may be directly related with vitamin D serum level. Some studies found that people with lower vitamin D serum level experienced a lower sleep quality. Consequently, this study aimed at determining the effect of vitamin D supplements on sleep point and quality in 20-50 year-old people with sleep disorders.
Methods: This double-blind, clinical trial was performed in Golestan Hospital of Ahvaz Jundishapur Medical Sciences University from November 2015 to February 2016 on 89 people with sleep disorders based on Pittsburgh Sleep quality index (PSQI). Participants of the study were selected based on inclusion and exclusion criteria. Patients under study were divided into two groups of vitamin D supplement and placebo recipients by random allocation. At the end of the study, the data on 89 subjects (44 in intervention group and 45 people in placebo group) were examined. Participants in intervention group received four edible pearls, each 50000 IU vitamin D, one in a fortnight. To placebo group, a placebo capsule (edible paraffin) was given one in a fortnight. Before and after intervention, Petersburg’s sleep quality questionnaire, Depression Anxiety Stress Scale (DASS-21) questionnaire, international physical activity questionnaire, general information questionnaire, sun exposure, vitamin D serum level and three-day food record questionnaire were assessed and recorded for all participants. To analyze data, Student's t-test, Chi-square test, ANCOVA, Mann-Whitney U test and Wilcoxon statistical tests were used.
Results: Mean score of Pittsburgh sleep quality questionnaire before and after intervention was 9.45±2.44 and 6.75±2.97 respectively (P=0.001) in interventional group and 10.51±3.14 and 9.73±3.04 respectively (P=0.18) in controls. Based on the results of the present study, at the end of the study score of Pittsburgh sleep quality questionnaire reduced significantly in vitamin D recipients as compared with placebo recipients (P=0.001).
Conclusion: This study shows that the use of vitamin D supplement reduced sleep score (PSQI) or improved sleep score, reduced sleep latency, increased sleep duration and increased subjective sleep quality after modifying confounding variables in adult people with sleep disorder.

Abstract
Background: Polycystic ovary syndrome (PCOS) is one of the most common neuroendocrine-metabolic disorders at the infertile age. Patients with PCO often at risk for secondary complications including metabolic difficulties (impaired glucose tolerance, insulin resistance, type 2 diabetes mellitus), reproductive (hirsutism, hypeandrogenism, infertility) and psychological features (worsened quality of life, anxiety, depression). Studies of the past decade suggest that the quality of life is important in the improvement of this syndrome. The purpose of this study was to provide an accurate pattern in the lifestyle of these women.
Methods: This case-control study was conducted to assess the lifestyle of patients with polycystic ovary syndrome who referred to Vali-e-Asr Infertile Clinic of Imam Khomeini Hospital, Tehran, from March to February 2015. After filling the consent form, 168 women participated in this study with the age range of 20-40 years and the body mass index (BMI) less than 28 m2/kg. The dimensions of lifestyle in this study were evaluated by the following questionnaires: general qualities of life (GHQ-28), Pittsburgh sleep quality, depression-anxiety-stress (DASS-42) and researcher-made demographic questionnaire.
Results: The mean of BMI and weight in study group were higher than control group (P= 0.002) (P< 0.001). Symptoms of PCOS such as irregular cycle (P< 0.001) and hirsutism (P< 0.001) in the study group were greater than the control group. Sleep problems such as drug use (P= 0.048), late sleep (P= 0.024), and sleep adequacy (P= 0.049) were also higher in the study group than control group.
Conclusion: These results indicate that environmental factors can easily effect on the quality of life in PCO women. The pattern of sleep is not desirable. Menstrual disorder effects on the mood and the impact of the low income generates negative emotions and affects their quality of life, since the cost of treatment for infertility is high for the low-income families. Therefore, this study indicates that having proper weight and proper sleep can help to plan a correct pattern of lifestyle in these patients.

Introduction of low to high frequencies bispectrum rate feature for deep sleep detection from awakening by electroencephalogram

Volume 76, Issue 5 (8-2018)
Abstract
Background: Accurate detection of deep sleep (Due to the low frequency of the brain signal in this part of sleep, it is also called slow-wave sleep) from awakening increases the sleep staging accuracy as an important factor in medicine. Depending on the time and cost of manually determining the depth of sleep, we can automatically determine the depth of sleep by electroencephalogram (EEG) signal processing. In this paper a new EEG bispectrum based feature is introduced for deep sleep discrimination.
Methods: This cross-sectional study was conducted at Isfahan University of Medical Sciences, Faculty of Advanced Technologies in Medicine, from February to October 2017. In this study a gray scale image was made of electroencephalogram bispectrum amounts and converted to binary image with Otsu’s Thresholding. Then the ratio of white bits in the above of the secondary diagonal to white bits in the down of secondary diagonal (low to high frequencies bispectrum rate) is extracted as a new feature. This feature is an effective method for detecting deep sleep from awakening.
Results: One of the important methods in biomedical signal processing is the use of the power spectrum or signal energy. In sleep studies, energy-related features have also been used to determine the depth of sleep. Low to high frequencies bispectrum rate is able to separate deep sleep from awakening by accuracy of 99.50 percent, while energy-based features as one of the most important approaches to sleep classification do not have this ability.
Conclusion: In this study we show that “Low to high frequencies bispectrum rate" feature has this capability to use in sleep staging. It is not used in previous works. The accuracy obtained in deep sleep separation from the awakening with the introduced feature (99.50 percent) is greater than the accuracy obtained by all the energy-based features (The simultaneous use of the 6 bands energy leads to 99.42 percent accuracy). This feature indicates the ratio of the phase coupling at low frequencies to high frequencies and can be used in all cases where the bispectrum is used (such as determining the depth of anesthesia).

Abstract
Background: Melatonin is one of the drugs which are used in the treatment of sleep problems, including insomnia and sleep deprivation. The aim of the present study was to evaluate the melatonin effect on sleep quality in patients with cancer.
Methods: This quasi-experimental study was performed on cancer patients with trouble sleeping who were treated with melatonin (3 mg per day) for a month. Sleep quality according to the Pittsburgh sleep quality index (PSQI) questionnaire was evaluated before and after taking melatonin. This study was conducted in the Oncology Clinic of Imam Reza Hospital, Kermanshah City in Iran from August 2016 to February 2018.
Results: There was a significant difference between the sleep quality of patients with cancer before and after taking melatonin (P<0.05). In other words, before taking melatonin, sleep quality of none of the patients was not optimal but after taking melatonin, the sleep quality of 52% of patients was satisfactory. Also, there was a significant difference between the components of subjective sleep quality (P<0.001), sleep latency (P<0.001), sleep duration (P<0.001), sleep efficiency rate (P<0.001), sleep disturbances (P=0.001), and daytime dysfunction (P<0.001) of patients with cancer before and after taking melatonin. There was no significant difference between the components of subjective sleep quality, sleep latency, sleep duration, sleep efficiency rate, sleep disturbances, and daytime dysfunction of cancer patients with age, sex, kind of cancer, and kind of metastasis before and after taking melatonin (P˃0.05).
Conclusion: According to the mentioned findings, it seems that the administration of melatonin to enhance sleep quality in patients with cancer is effective.

Volume 78, Issue 8 (11-2020)
Abstract
Background: Polycystic ovary syndrome is the most common disorder in the endocrine system. Hyperandrogenism, hyperinsulinemia, chronic ovulation, and infertility are important Complications of PCOS. Health-related quality-of-life (HRQoL) has a significant reduction in women with polycystic ovary syndrome (PCOS). This reduction can be due to many disorders including: menstrual and sleep disorders, hirsutism, marital issues, infertility, and emotional/psychosocial problems. The purpose of current study was to investigate the role of sleeping and other environmental factors affecting the quality of life in patients with polycystic ovary syndrome. 
Methods: This case/control study was conducted in 2017 in two groups: control and study (PCOS). The inclusion criteria were women aged 20-40 with a body mass index (BMI)<28. Exclusion criteria included no disease and no medication for all women. The participants were 180 women who were referred to the infertility center of Imam Khomeini Hospital in Tehran. Four questionnaires including Demographics (40 questions), sleep quality (PSQI) (19 items 0-3), quality of life (GHQ) (28 items) and psychometric (DASS-42) with their consent form were filled out. Student’s t-test and Chi-square were used to compare the variables between two groups and the Pearson correlation coefficient to examine the relationship between lifestyle dimensions.
Results: The mean weight and BMI (P=0.002), hirsutism and irregular menstruation cycle in the study group were greater than the control (P<0.001). In the study group the mean score of the sleep questionnaire in three dimensions: sleep problems (P=0.024), drug use (P=0.048), and the sufficiency of sleep (P=0.049) were higher than control.
Regression analysis showed that there is a significant relationship between quality of life and menstruation cycle (P=0.046), as well as the three dimensions of negative affecting situations with family income (respectively, 0.015, 0.016 and P=0.035).
Conclusion: The environmental factors can easily affect the quality of life in PCO women. Sleep patterns were not favorable, and the effect of menstruation on mood and low family income caused negative emotions in women with PCOS.

Volume 82, Issue 10 (1-2025)
Abstract
Background: With the rising survival rates among individuals with colorectal cancer, improving quality of life and reducing the risk of recurrence have become key priorities in supportive care. High-intensity interval training (HIIT), due to its pronounced effects on physical function, inflammatory markers, and tumor-related indicators, has emerged as a promising intervention. This study aimed to evaluate the effect of an eight-week high-intensity interval training (HIIT) program on serum carcinoembryonic antigen (CEA) levels, quality of life, and sleep quality in female survivors of colorectal cancer.
Methods: This quasi-experimental study employed a pretest-posttest control group design and was conducted from July to September 2021 at the Kosar Women’s Sports Complex in Kermanshah, Iran. Twelve female colorectal cancer survivors (mean age=55.66±4.99 years) were randomly assigned to either an experimental (n=6) or control group (n=6). The experimental group participated in a supervised HIIT program for eight weeks. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and quality of life was evaluated using the World Health Organization Quality of Life (WHOQOL) questionnaire.
Results: Post-intervention analysis revealed a non-significant increase in CEA levels in the experimental group (mean±SD: 2.49±0.79; CI95%: 1.66-3.33; P=0.456), while the control group showed a statistically significant reduction (mean±SD: 1.04±0.22; CI95%: 0.84-1.25; P=0.044). However, significant improvements were observed in both sleep quality (mean±SD: 5.00±2.19; CI95%: 3.27-6.72; P=0.027) and quality of life (mean±SD: 77±9.40; CI95%: 84.11-88; P=0.028) within the experimental group. No significant changes were reported in the control group for either variable.
Conclusion: Findings suggest that high-intensity interval training may serve as an effective non-pharmacological intervention for enhancing sleep quality and overall quality of life in female colorectal cancer survivors. Nevertheless, the effects of HIIT on biological markers such as CEA require further investigation through larger and longer-term studies.
