  • Purpose: Shift work disrupts the synchronization between the human biological clock and the environment. Sleep disturbances are common for shift work nurses, and may threaten patient safety. This study was done to investigate the sleep characteristics and medication errors (ME) of intensive care unit (ICU) nurses who work shifts, and ascertain if there is an association between these factors. Methods: Data were collected using a self-report questionnaire from 126 ICU nurses on three shifts. Collected data included their sleep characteristics including sleep patterns and sleep disturbances, and ME for the past 2 weeks. Results: There were significant differences in sleep duration and sleep latency according to shift. Day shift nurses had the shortest sleep duration, and their sleep latency was the longest (about 49 minutes) compared to nurses on evening and night shifts; 54% reported sleep disturbances, 16% experienced ME, and among these nurses 50% were on the night shift. Logistic regression analysis revealed significant associations between nurses' sleep duration and ME (adjusted OR 0.52 [95% CI 0.32-0.85]). Conclusions: The results confirmed that shift work nurses in the ICUs experience sleep disturbance, and that less sleep is associated with ME.

  • Purpose: The purpose of this study was to examine fatigue, sleep disturbances, and quality of life (QOL) among patients with breast cancer receiving radiotherapy. Methods: A cross-sectional, descriptive design was used. Data were collected through questionnaires distributed to 201 breast cancer patients in a hospital. The data were analyzed using SPSS 21.0. Results: The fatigue scores showed significant differences depending on exercise and duration since diagnosis. The sleep disturbance scores showed significant differences depending on duration since diagnosis. QOL scores showed significant differences depending on exercise, duration since diagnosis, and treatment site. Fatigue and sleep disturbances (r=.40, p<.001) showed statistically significant positive correlations, while fatigue and QOL (r=-.55, p<.001), and sleep disturbances and QOL (r=-.45, p<.001) showed statistically significant negative correlations. The multiple regression analysis, which was used to determine the variables influencing on QOL after radiotherapy, resulted in a significant regression model (F=23.88, p<.001), which accounted for approximately 45% of the explanatory power. Fatigue (${\beta}=-.39$, p<.001) and sleep disturbances (${\beta}=-.27$, p<.001) were revealed to adversely affect quality of life. Conclusion: The nursing intervention is necessary to reduce fatigue and sleep disturbance and to promote exercise in order to enhance QOL of patients with breast neoplasm while receiving radiotherapy.

  • Background: Pregnancy is associated with a number of physical, emotional, and biological changes that can exacerbate maternal psychological disturbances, such as body image concerns and depression. Sleep disturbances during pregnancy can also have adverse impacts. This study aimed to determine the prevalence of depression, sleep disturbances, and body image concerns among pregnant women. The study also examined the relationship between these factors and pregnancy-related variables, such as bad obstetric history and whether the pregnancies were unplanned. Methods: A cross-sectional study of 146 pregnant patients was conducted at a tertiary care center over 15 months. The patients were administered the Beck Depression Inventory, Pittsburgh Sleep Quality Index, and Body Image Concern Inventory questionnaires. Contingency tables, Fisher exact test, and Spearman correlation were used to identify underlying relationships. Results: The prevalence of depression was 22.6%. Although body image disturbance was noted in only 2.7% of patients, 46.6% had poor sleep quality. Poor sleep was associated with primigravida status. Bad obstetric history and unplanned pregnancy were associated with depression. Depression was found to be significantly correlated with body image disturbances and poor sleep quality. Conclusion: Psychiatric disorders were prevalent during pregnancy. This study highlights the importance of screening for depression in pregnant patients. Counselling and caregiver education can be useful for mitigating psychological disturbances. Management of pregnancies by multidisciplinary teams that include psychiatrists could be immensely useful in improving the pregnancy experiences of patients.

  • Worldwide, caffeine is among the most commonly used stimulatory substances. Unfortunately, significant caffeine consumption is associated with several adverse effects, ranging from sleep disturbances (including insomnia) to cardiovascular problems. This study investigates whether treatment with the Evodia rutaecarpa aqueous extract (ERAE) from berries and its major molecular component, evodiamine, can reduce the adverse caffeine-induced sleep-related and excitation effects. We combined measurements from the pentobarbital-induced sleep test, the open field test, and the locomotor activity test in mice that had been dosed with caffeine. We found that ERAE and evodiamine administration reduced the degree of caffeine-induced sleep disruption during the sleep test. Additionally, we found that evodiamine significantly inhibits caffeine-induced excitation during the open field test, as well as decreasing hyperlocomotion in the locomotor activity test. Additional in vitro experiments showed that caffeine administration decreased the expression of ${\gamma}$-aminobutyric acid $(GABA)_A$ receptor subunits in the mouse hypothalamus. However, evodiamine treatment significantly reversed this expression reduction. Taken together, our results demonstrate that ERAE and its major compound, evodiamine, provide an excellent candidate for the treatment or prevention of caffeine-induced sleep disturbances and excitatory states, and that the mechanism of these beneficial effects acts, at least in part, through the $GABA_A$-ergic system.

  • Purpose : Chronic neck pain negatively impacts the quality of life and causes various problems in daily life due to pain, insomnia, and sleep disturbances in patients with this condition. Therapeutic interventions to solve these problems in rehabilitation and physical therapy are being introduced; however, the evidence of the efficacy of myofascial release (MFR) is still insufficient. This study aimed to investigate the effects of applying MFR on pain, insomnia, and sleep disturbances in patients with chronic neck pain. Methods : Ten patients with chronic neck pain were randomly selected and grouped into the experimental group (n1 = 10) and control group (n2 = 10) by cross-over design. Pain was measured before and after MFR intervention. Moreover, insomnia was measured only after MFR intervention. Polysomnography was performed after MFR intervention. Wilcoxon signed rank test and Mann-Whitney U test were used for the visual analog scale (VAS). Independent sample t-test was separately performed to measure insomnia and sleep. Results : After MFR intervention, the VAS score of the experimental group (p = 0.005) significantly decreased than that of the control group (p = 0.002). The insomnia score of the experimental group significantly decreased than that of the control group (p = 0.001). The total sleep time (p = 0.001), sleep efficiency (p = 0.001), and sleep latency (p = 0.001) of the experimental group significantly increased than those of the control group in the polysomnographic measurement. Conclusion : The application of MFR of the neck and upper trunk may have a positive effect on pain, insomnia, and sleep disturbances in patients with chronic neck pain. It was also suggested that an objective and quantitative polysomnography can be used more often in the field of rehabilitation and physical therapy.

  • Previous research has identified the biological, psychological, and social factors that confer an elevated risk for suicide. Evidence suggests that sleep disturbances are one of the risk factors that predict an increased risk for suicidal behaviors. Both sleep disorders and general sleep complaints are linked to higher levels of suicidal ideation and depression, as well as increased rates of suicide and suicide attempts. The causal mechanism of this association is not clear. For example, it is not known if insomnia is an independent phenomenon that if interrupted could prevent the emergence of a mental disorder, or if insomnia is a symptom of another developing illness. Hypofrontality, HPA dysfunction, and an impaired serotonergic system are potential mechanisms underlying the association of sleep disturbances and suicidal behavior. Future research is necessary to examine the specific mechanism of this association between sleep and suicide, which may lead to an effective intervention and diminished suicide risk.

  • Anger is a multi-dimensional concept ranging from feeling irritable to violent aggression. A growing body of literature suggests the relevance of sleep in regard to anger. The current study aims to review previous studies on the association between anger and diverse aspects of sleep including sleep disruption, chronotype, sleep disorders and sleep deprivation. An association between sleep and anger has been observed starting in the early stage of life, with sleep of infants or toddlers affecting emotional and behavioral aspects of anger. However, the association between anger and sleep is not clear in adolescents and might be due to the effects of psychosocial factors on both sleep and anger during adolescence. Subjective but not objective sleep disturbances of adults have been also associated with anger. Evening types showed more anger, which might be mediated by psychological characteristics or social jet lag of evening people. Increased anger has also been found in those with insomnia, sleep apnea, or experimental sleep-deprivation. Previous studies have reported that diverse sleep disturbances are related to anger. Future study assessing the various sleep or circadian indices and considering the multidimensional aspects of anger are needed.

  • Purpose: This study aimed to explore the knowledge and performance of sleep hygiene among nurses with shift work schedules and examine the influence on sleep disturbance. Methods: A total of 199 shift-work nurses from a tertiary hospital were included in the study. To examine the knowledge and performance of sleep hygiene, the participants were asked to respond to a self-reported survey. To assess sleep disturbance, the General Sleep Disturbance Scale was used. Descriptive statistics and multiple linear regression were applied using the SPSS/WIN 21.0 program to analyze the data. Results: Both the knowledge and performance of sleep hygiene among nurses with shift work schedules were measured at a moderate level. Nurses' knowledge and the performance of sleep hygiene was not significantly associated with sleep disturbance, whereas age, experience with shift-working, and perceived health status were significantly associated. Conclusion: Strategies for providing more accurate information and motivating better sleep hygiene would help to enhance sleep hygiene in nurses with shift work schedules. Further studies examining the association of knowledge and the performance of sleep hygiene with sleep disturbances in nurses with shift work schedules are needed.

  • Menopause, the cessation of menstruation caused by the decline in estrogen production, occurs in 95% of women between 40 and 60 years. Sleep disturbance is a frequent complaint during the perimenopause period. In contrast to premenopausla women, menopausal women experience more reduction in the total sleep hours and report more sleep disturbances, such as insomnia, noctiria and sleep disordered breathing. But the prevalence, etiology and treatment of sleep disturbances in menopause are still controversal. So further investigations are required to elucidate the factors that account for the differences in sleep disturbance between premenopausal and postmenopausal women. There are suggestive data that estrogen and progesterone deficiency may increase the susceptibility for sleep disorder in menopause. Furthermore, there are suggestive evidence from observational studies and a limited number of randomized, controlled trials that hormone replacement therapy after menopause improves sleep. However, the clinical relevance of hormone replacement therapy is unproved. So the overall benefit of hormonal replacement in postmenopausal women with sleep related disorders should be individualized to avoid potential side effects. Several studies evaluated the role of melatonin, because this hormone has effects on core body temperature & insomnia. But the exact dosage and the effects of long-term use of melatonin are unclear. So, caution is indicated in melatonin administration.
