A scoping review of the effect of chronic stretch training on sleep quality in people with sleep disorders.

PURPOSE: The widespread and health-detrimental sleep disorders have resulted in stretching exercises being investigated as a non-drug solution for enhanced sleep quality. However, a comprehensive understanding of the impact of stretching exercises on individuals with sleep disorders is lacking. METHODS: This scoping review systematically maps the existing literature and identifies research gaps on the impact of stretching exercises on sleep quality in individuals with sleep disorders. RESULTS: Sixteen eligible studies were included, where the weighted mean changes indicate a positive trend in sleep quality improvement, ranging from trivial to very large magnitudes. However, concerning the individual study results only 5 out of 16 studies reported significant improvements. Notable enhancements include a small 1.22% overall sleep quality improvement, a large 6.51% reduction in insomnia severity, a large 8.88% increase in sleep efficiency, a moderate 4.36% decrease in sleep onset latency, a large 8.27% decrease in wake after sleep onset, and a very large 14.70% improvement in total sleep time. Trivial changes are noted in sleep duration (0.58%), sleep disturbance reduction (0.07%), and daytime dysfunction reduction (0.19%). Likely mechanisms for the improvement of sleep include autonomic nervous system modulation, muscle tension relief, cortisol regulation, enhanced blood circulation, and psychological benefits such as stress reduction and mood enhancement. CONCLUSION: There is little evidence that stretching exercises positively impact sleep quality in individuals with sleep disorders. Additionally, further research is vital for designing optimal protocols, understanding of the long-term effects, and clarification of the mechanisms.

Anxiety, Depression, and Quality of Sleep Vary in Their Correlation to Postoperative Outcomes of Rotator Cuff Repair: A Prospective Study.

Background/Objectives: Recent studies imply that psychological factors and sleep quality play a role in the outcomes of surgical procedures, including in orthopedic surgery. The aim of the present study is to evaluate possible correlations between preoperative depression, anxiety, and quality of sleep and functional 6-month postoperative scores in patients having undergone rotator cuff repair (RCR). Methods: All patients included in the study performed the Hospital Anxiety and Depression Scale (HADS) and Pittsburgh Sleep Quality Index (PSQI) questionnaires preoperatively and 36-item Short-Form Health Survey (SF-36), Oxford Shoulder Score (OSS), Shoulder Pain and Disability Index (SPADI), and PSQI questionnaires at the six-month postoperative follow-up. A total of 47 patients were included in the analysis. Results: Statistically significant differences between preoperative anxious and not-anxious groups were found in the postoperative SF-36 Physical Component Summary (PCS) and Mental Component Summary (MCS) scores and PSQI score. The correlation of the preoperative depression score to postoperative outcome measures revealed a strong positive correlation between the preoperative HADS-D score and the 6-month PCS, MCS, and OSS scores. The correlation of preoperative sleep quality to postoperative outcome measures revealed a strong positive correlation between the preoperative PSQI score and 6-month MCS score. Conclusions: Anxious patients had worse postoperative RCR outcomes. Depression may be influenced by factors related to RC pathology; however, there were no statistically significant correlations. Sleep quality generally improves postoperatively, and no significant association was found between bad preoperative sleepers and worse outcomes.

A Cross-Sectional Study on Neuropathic Pain Associated With Quality of Sleep in Spondylosis Patients.

INTRODUCTION: Neuropathic pain (NP) is common in spondylosis patients. Cervical and lumbar spondylosis are more common in the elderly population. Spondylosis patients also suffer from poor quality of sleep (QOS). This study aims to find a correlation between NP and QOS in spondylosis patients. METHODS: We conducted a cross-sectional study and analyzed data using the chi-square test to correlate the NP with QOS. The Pittsburgh Sleep Quality Index (PSQI) and the Leeds Assessment of Neuropathic Symptoms and Signs, Self-complete (S-LANSS) questionnaires were used to assess QOS and evaluate neuropathic pain, respectively. Spondylosis was diagnosed based on the history, clinical examination, and radiological findings. RESULTS: A total of 72 spondylosis patients, with a mean age of 47.35 years, were included in this study. Out of 72 subjects, 52 (72.2%) patients had neuropathic pain (NP group), and 20 (27.8%) patients had non-neuropathic pain (non-NP group). In the NP group, 41 patients (78.8%) had poor QOS, while 11 (21.2%) had good QOS. In the non-NP group, eight (40%) had poor QOS, and 12 (60%) had good QOS. CONCLUSION: This study concludes that neuropathic pain is associated with poor quality of sleep in spondylosis patients.

Comparison of sleep quality between outpatient and hospitalized children with respiratory tract dysfunction.

OBJECTIVES: The main objective of the study to compare the effect of hospitalized and outpatient settings on quality of sleep in children with respiratory tract dysfunction. METHODOLOGY: A descriptive correlational study was carried out at Dhi-Qar Health Directorate pediatric hospitals. The period of the study was from the November 19, 2023 to March 10, 2024. Purposive sample (non-probability) of 250 children (male and female). A total of (125) children were chosen from the children whose admitted to the hospitals, and a total of (125) children were chosen from the outpatient settings. The study instrument consisted of three parts: the sociodemographic sheet, clinical diagnosis sheet, and sleep quality scale. The questionnaire was modified according to experts' recommendation to use it for children with respiratory tract dysfunction. The questionnaire was evaluated by a panel of 15 experts from diverse medical and nursing professions. Both descriptive and inferential statistics were used to analyze the data. RESULTS: The study findings that effect outpatient settings have more effect from hospitalized settings on quality of sleep in children with respiratory tract dysfunction (M ± SD = 1.322 ± 0.1522). CONCLUSION: A study showed that the quality of sleep in children with respiratory tract dysfunction was generally average, whether in hospitalized or outpatient settings, outpatient settings had greater difficulties falling asleep and waking than children in hospitalized.

The association of stress perception on anxiety, depression and sleep quality in parents of children with burns: The moderating effect of social support.

OBJECTIVE: Few studies have explored the mental health status of parents of children with burns and the moderating effect of social support on them. METHODS: A survey was performed with parents of 112 burn-injured children at a burn center in China. Their perceived stress, anxiety, depression, sleep quality, and social support were measured by the Chinese Perceived Stress Scale, Hospital Anxiety and Depression Scale, Pittsburgh Sleep Quality Index, and Perceived Social Support Scale. RESULTS: ➀ The prevalence of anxiety (46.43%), depression (52.67%) and poor sleep quality (43.75%) of parents indicated that they experienced emotional and sleep disorders;➁ The perceived stress was positively correlated with sleep quality, anxiety and depression（P＜0.01), and negatively correlated with perceived social support (p＜0.05); ➂ Social support had a significant moderating effect on their perceived stress and anxiety, depression, but not on their sleep quality. With high social support, parental perceived stress had a significant positive association on anxiety and depression, while with low perceived social support, parental perceived stress had no significant association on anxiety and depression. CONCLUSION: Parents of burned children had increased stress, obvious symptoms of anxiety and depression, and poor sleep quality. Social support had a significant buffering effect on them under low pressure, and high pressure will hinder the buffering effect of social support on stress. Therefore, the ideal services to improve mental health should be provided for them to face different levels of stress.

Does chronic urticaria affect quality of sleep and quality of life?

Background: Urticaria affects a wide range of daily activities and social relationships. It has a severe impact on quality of life (QOL) and causes psychological problems. Objective: was to assess the impact of chronic urticaria (CU) on quality of sleep, the levels of depression, anxiety, QOL and their interaction with each other and their relation to disease related factors. Patients and methods: The study included 25 patients with CU and 25 healthy controls. Urticaria Activity Score (UAS) was used for objective evaluation of the intensity of urticaria. Patients completed a 10-cm visual analogue score (VAS) indicating the overall severity of their itching over the previous 2 weeks. The Dermatology Life Quality Index (DLQI) was used to evaluate patients' QOL. Patients were also assessed for anxiety and depression with the Hospital Anxiety and Depression Scale (HADS). Pittsburgh Sleep Quality Index (PSQI) was used for evaluation of sleep quality and sleep disturbances. Results: In our CU patients the mean of UAS7 score was 39.72 ± 2.76 and the mean of VAS score was 28 ± 1.34. The mean of DLQI score was 24.8 ± 4.37 indicating severe impact of QOL. CU patients had higher total HADS score when compared to controls; 72% of the patients had depression and 92% had anxiety. By using PSQI, CU patients had significantly longer sleep latency onset, shorter total sleep duration, lower sleep efficiency and higher PSQI scores compared to controls. Conclusion: CU highly affects the QOL of patients and is associated with higher levels of anxiety, depression and poor sleep quality.

Spectrum of sleep-disordered breathing and quality of sleep in adolescent and adult patients with spinal muscular atrophy.

Sleep-disordered breathing is common among children with spinal muscular atrophy, but has been hardly studied among adult subjects. Little is known about sleep quality in spinal muscular atrophy. The aims of this study were to evaluate occurrence and characteristics of sleep-disordered breathing and subjective sleep quality among adolescent and adult patients with spinal muscular atrophy type 2 or 3. Twenty patients aged 33.9 ± 15.2 years were studied. They underwent nocturnal cardiorespiratory monitoring, lung and muscular function evaluation, and were administered the Pittsburgh Sleep Quality Index questionnaire. Nineteen patients showed sleep-disordered breathing, with obstructive events in seven subjects and non-obstructive events in the remaining 12. In the latter group, 10 patients showed pseudo-obstructive hypopneas. Patients with non-obstructive sleep-disordered breathing were younger (p = 0.042), had a lower body mass index (p = 0.0001), were more often affected by spinal muscular atrophy type 2 (p = 0.001), and showed worse impairment of respiratory function than patients with obstructive sleep-disordered breathing. Ten patients were classified as poor sleepers and 10 patients good sleepers. In the whole sample, sniff nasal inspiratory pressure proved to be the only independent predictor of sleep quality (p = 0.009). In conclusion, sleep-disordered breathing is common even among adult patients with spinal muscular atrophy type 2 and 3, and may show either obstructive or different types on non-obstructive features. A worse respiratory muscle function is associated to non-obstructive sleep-disordered breathing and poorer sleep quality. Sleep quality should receive greater attention especially in patients with spinal muscular atrophy type 2, who have a poorer respiratory muscle function, as it could affect their quality of life.

Path of Physical Exercise's Impact on Deviant Behavior Among Chinese Adolescents.

Purpose: Physical exercise is an important predictor of deviant behavior in adolescents; however, the paths and mechanisms underlying this relationship remain understudied. Patients and Methods: This cross-sectional study used education tracking data of 8725 Chinese adolescents (4453 males, 4240 females, average age 14 ± 0.73) to construct a chain mediation model to explore whether sleep quality and mental health mediated the relationship between physical exercise and adolescent deviant behavior. Results: The results show that physical exercise cannot directly predict adolescent deviant behavior; however, it can indirectly affect deviant behavior through the mediating effect of sleep quality and mental health as well as the chain mediating benefit of "sleep quality-mental health". Conclusion: Sleep quality and mental health are important internal factors of physical exercise that inhibit deviant adolescent behavior. The lack of physical activity and poor sleep quality should be prioritized in interventions regarding deviant behavior among Chinese adolescents.

Association Between Sleep Efficiency Variability and Cognition Among Older Adults: Cross-Sectional Accelerometer Study.

Background: Sleep efficiency is often used as a measure of sleep quality. Getting sufficiently high-quality sleep has been associated with better cognitive function among older adults; however, the relationship between day-to-day sleep quality variability and cognition has not been well-established. Objective: We aimed to determine the relationship between day-to-day sleep efficiency variability and cognitive function among older adults, using accelerometer data and 3 cognitive tests. Methods: We included older adults aged >65 years with at least 5 days of accelerometer wear time from the National Health and Nutrition Examination Survey (NHANES) who completed the Digit Symbol Substitution Test (DSST), the Consortium to Establish a Registry for Alzheimer's Disease Word-Learning subtest (CERAD-WL), and the Animal Fluency Test (AFT). Sleep efficiency was derived using a data-driven machine learning algorithm. We examined associations between sleep efficiency variability and scores on each cognitive test adjusted for age, sex, education, household income, marital status, depressive symptoms, diabetes, smoking habits, alcohol consumption, arthritis, heart disease, prior heart attack, prior stroke, activities of daily living, and instrumental activities of daily living. Associations between average sleep efficiency and each cognitive test score were further examined for comparison purposes. Results: A total of 1074 older adults from the NHANES were included in this study. Older adults with low average sleep efficiency exhibited higher levels of sleep efficiency variability (Pearson r=-0.63). After adjusting for confounding factors, greater average sleep efficiency was associated with higher scores on the DSST (per 10% increase, ß=2.25, 95% CI 0.61 to 3.90) and AFT (per 10% increase, ß=.91, 95% CI 0.27 to 1.56). Greater sleep efficiency variability was univariably associated with worse cognitive function based on the DSST (per 10% increase, ß=-3.34, 95% CI -5.33 to -1.34), CERAD-WL (per 10% increase, ß=-1.00, 95% CI -1.79 to -0.21), and AFT (per 10% increase, ß=-1.02, 95% CI -1.68 to -0.36). In fully adjusted models, greater sleep efficiency variability remained associated with lower DSST (per 10% increase, ß=-2.01, 95% CI -3.62 to -0.40) and AFT (per 10% increase, ß=-.84, 95% CI -1.47 to -0.21) scores but not CERAD-WL (per 10% increase, ß=-.65, 95% CI -1.39 to 0.08) scores. Conclusions: Targeting consistency in sleep quality may be useful for interventions seeking to preserve cognitive function among older adults.

[Effect of Lemiancao on Insomnia in Patients With Depressive Disorder].

Objective To investigate the effect of Lemiancao on insomnia in the patients with depressive disorder. Methods Totally 79 patients diagnosed with both insomnia and depressive disorder from February to August in 2022 in Peking University Sixth Hospital were selected and classified into a control group(n=40) and a Lemiancao group(n=39).The Lemiancao group received routine nursing and medical treatment combined with Lemiancao training in the morning and evening every day,while the control group received routine nursing and medical treatment.The sleep status was evaluated based on the Pittsburgh sleep quality index(PSQI),insomnia severity index(ISI),and 36-item short-form health survey(SF-36) before and after treatment. Results The general information of patients showed no significant difference between the two groups(all P>0.05).After a 2-week intervention with Lemiancao training,the Lemiancao group showed lower PSQI and ISI scores and higher SF-36 score than the control group(all P<0.001). Conclusion Lemiancao training has therapeutic effects on insomnia in the patients with depressive disorder.

Assessment of the quality of nursing work life and its related factors among critical care nurses.

Background: Quality of work life (QWL) refers to the degree to which employees contribute to the organization's goals while also experiencing personal and professional satisfaction. This study conducted to evaluate the quality of nursing work life (QNWL) level and its associated factors among nurses working in critical care units. Methods: A convenience sample technique among critical care nurses in Jordan by using a cross-sectional, descriptive design. A self-reported questionnaire was used. A Pittsburgh Sleep Quality Index (PSQI), and the Andersson and Lindgren questionnaires scale were used in data collection. Results: The total mean scores of QNWL were M = 86.17 (SD = 35.12), which is slightly below the expected middle value (87.5). The nurses have a higher psychological relation, M = 18.28 (SD = 8.99), whereas they have the lowest competence development, M = 11.44 (SD = 5.56). There was statistical significance between workplace noise, and workplace sources of noise, quality of sleep and QNWL. Conclusion: The outcomes also highlighted the significance of undertaking additional interventional research studies in the future in order to identify practical strategies to improve nurses QNWL. As a result, the nursing care given to the patients and their families may be improved.

The Interplay of Anxiety, Depression, Sleep Quality, and Socioeconomic Factors in Somali Hemodialysis Patients.

OBJECTIVE: This study aimed to assess anxiety, depression, and sleep quality in kidney failure patients receiving hemodialysis (HD) in Somalia and examine the relationship between anxiety, depression, and sleep quality. METHODS: We conducted a study with 200 kidney failure patients on HD treatment for over 3 months. Participants completed sociodemographic questionnaires, the Patient Health Questionnaire-9 (PHQ-9), the Hospital Anxiety and Depression Scale (HADS), the Insomnia Severity Index (ISI), and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: Among the 200 participants (mean age = 52.3; SD = 14.13), 58.5% were men, 64% had CKD for 1-5 years, and 52.6% received HD for 1-5 years. Depressive symptoms were found in 61.5% (PHQ-9) and 37.5% (HADS depression subscale) of HD patients. Poor sleep quality (PSQI) was observed in 31.5% and significantly correlated with PHQ-9 (rs = 0.633), HADS anxiety (rs = 0.491), and HADS depression (rs = 0.529). The ISI score correlated significantly with PHQ-9 (rs = 0.611), HADS anxiety (rs = 0.494), and HADS depression (rs = 0.586). All PSQI components correlated with depression and anxiety, except sleep medication use. Hierarchical regression analysis revealed that HADS anxiety (ß = 0.342) and HADS depression (ß = 0.372) predicted ISI scores. HADS anxiety (ß = 0.307) and HADS depression (ß = 0.419) predicted PSQI scores. CONCLUSIONS: Higher anxiety and depression levels negatively correlated with various dimensions of sleep quality in kidney failure patients. Early identification and appropriate management of these psychological disturbances are crucial for enhancing patients' overall quality of life.

Effects of melatonin on blood pressure, arterial stiffness and quality of life in postmenopausal women: A randomized controlled trial.

OBJECTIVES: Studies suggest that melatonin may promote cardiovascular protection. Previous trials have primarily been performed on co-morbid patients. Little information exist on the effect in postmenopausal women with general good health. DESIGN, PARTICIPANTS AND INTERVENTION: In a double-blinded placebo-controlled study, we randomized 41 postmenopausal women to either 10 mg melatonin per day or placebo for 3 months. OUTCOME MEASURES: Outcomes of the trial was changes in blood pressure, pulse wave velocity (PWV), and quality of sleep evaluated by Pittsburgh Sleep Quality Index (PSQI). RESULTS: Thirty-nine women completed the study. Mean age was 63 years (range 55-75 years). Over the 3 months of the trial, PWV did not differ between groups: Placebo 1.1% (IQR -2.1;9.9) vs. melatonin 0.0% (IQR-9.8;4.1), p = 0.43). The were no significant differences in blood pressure bewteen melatonin and placebo group. Both groups had a pour quality of sleep at baseline (placebo: PSQI 6.0 (IQR 3.3; 8.8) vs. melatonin PSQI 6.0 (IQR 3.0; 10.0), p = 0.94), which did not change in response to treatment. CONCLUSION: In healthy postmenopausal women, supplementation with 10 mg melatonin was well-tolerated, but we did not observe any significant improvements in pulse wave velocity, blood pressure or quality of sleep compared with placebo.

The effect of using a sports application on the quality of sleep in patients with heart failure: a randomized clinical trial study.

BACKGROUND: Patients with heart failure often suffer from sleep disorders. Due to the side effects of medications used to treat this disorder, non-pharmacological methods may be used to improve these patients' sleep quality. This study aimed to determine the effect of a sports application on sleep quality in patients with heart failure. METHODS: In this single-blinded randomized clinical trial, 60 patients aged 30-70 referred to Shafa Hospital in Kerman were randomly assigned to control (n = 30) and intervention (n = 30) groups based on convenience sampling. The intervention group used the sports application for eight consecutive weeks. Data was collected using a demographic questionnaire and the Pittsburgh Sleep Quality Index (PSQI). An independent t-test and a Mann-Whitney U test were used for comparisons between groups and paired t-tests and Wilcoxon tests were used for comparisons within groups. RESULTS: The data analysis revealed a significant difference in sleep quality scores between the two groups after the intervention, meaning that the intervention group had better sleep quality than the control group (P < 0.05). CONCLUSIONS: As a result of the study, it was found that the sport application improved the quality of sleep in patients with heart failure. Our recommendation is for healthcare providers to use this sports application to present educational content related to physical activity and improve the sleep quality of patients.

Effects of vagus nerve stimulation on the quality of sleep and sleep apnea in patients with drug-resistant epilepsy: A systematic review.

OBJECTIVE: The objective was to systematically evaluate the current evidence surrounding the effect of vagus nerve stimulation (VNS) on quality of sleep and obstructive sleep apnea (OSA) among patients with epilepsy. METHODS: A literature search was conducted using the Embase and MEDLINE databases. Studies were included if they involved patients with drug-resistant epilepsy treated with VNS and used validated tools to report on quality of sleep or sleep apnea. The literature search yielded 112 citations related to VNS and sleep quality, and 82 citations related to sleep apnea. Twelve articles were included in the review, of which five measured quality of sleep among patients who underwent VNS, six studies measured sleep apnea, and one study measured both outcomes. RESULTS: Studies measuring quality of sleep used different methods, including sleep quality questionnaires and the percentage of sleep in each cycle. Studies also varied in patient populations, the use of control groups, and whether multiple measurements were taken for each patient. Some studies found improved sleep quality after VNS, whereas others found reductions in deep sleep stages. Additionally, mixed results in sleep quality were found when comparing patients with epilepsy who received VNS treatment versus patients with epilepsy who did not receive VNS treatment. Variables such as VNS intensity and age could potentially confound quality of sleep. Studies measuring sleep apnea consistently found increased proportions of patients diagnosed with OSA or increased sleep index scores after VNS implantation. SIGNIFICANCE: Overall, the effect of VNS on quality of sleep remains unclear, as studies were very heterogeneous, although the effect on sleep apnea has consistently shown an increase in sleep apnea severity indices after VNS implantation. Future studies with consistent measures and discussions of confounding are required to determine the effect of VNS on quality of sleep, and the effect of VNS parameters should be further explored among patients who develop sleep apnea.

Non-opioid versus Opioid Peri-operative Analgesia In Neurosurgery (NOPAIN): Study protocol for a multi-centric randomised controlled trial.

Background and Aims: Many patients suffer from post-operative pain after neurosurgery despite using intra-operative opioids. Opioid side effects are problematic in neurosurgical patients. Hence, non-opioid alternatives for the management of nociception and pain are needed. Previous studies comparing opioids with non-opioids in the neurosurgical population were few, from single centres, of small sample sizes and were equivocal in findings, which prevented change in clinical practice. To overcome these limitations, we are conducting a multi-centre trial with objectives to compare intra-operative rescue opioid requirements and post-operative pain scores (primary objectives), adverse events, quality of recovery from anaesthesia, quality of sleep and patient satisfaction during hospital stay, and persistent post-surgical pain and quality of life at 3 and 6 months (secondary objectives) in patients receiving opioid and non-opioid analgesia for brain tumour surgeries. Methods: This study protocol describes the methodology of a multi-centre randomised controlled trial. Ethics committee approval has been obtained from all five centres, the trial has been registered with the Clinical Trial Registry- India, and insurance has been obtained for this investigator-initiated funded study. In patients undergoing supra-tentorial brain tumour surgery (population), we will compare fentanyl (intervention) 1 µg/kg/h with dexmedetomidine (comparator) 0.5 µg/kg/h administered during surgery with regards to intra-operative rescue opioid requirement and post-operative pain (primary outcomes). Results: We describe the study protocol of the multi-centre trial (protocol version 2, dated 29/01/2022). The first patient was recruited on 19/10/2022, and we will complete recruitment before March 2024. Conclusion: We expect our study to establish dexmedetomidine as an effective non-opioid analgesic vis-à-vis opioids in the neurosurgical population.

Comparison of Polysomnography, Single-Channel Electroencephalogram, Fitbit, and Sleep Logs in Patients With Psychiatric Disorders: Cross-Sectional Study.

BACKGROUND: Sleep disturbances are core symptoms of psychiatric disorders. Although various sleep measures have been developed to assess sleep patterns and quality of sleep, the concordance of these measures in patients with psychiatric disorders remains relatively elusive. OBJECTIVE: This study aims to examine the degree of agreement among 3 sleep recording methods and the consistency between subjective and objective sleep measures, with a specific focus on recently developed devices in a population of individuals with psychiatric disorders. METHODS: We analyzed 62 participants for this cross-sectional study, all having data for polysomnography (PSG), Zmachine, Fitbit, and sleep logs. Participants completed questionnaires on their symptoms and estimated sleep duration the morning after the overnight sleep assessment. The interclass correlation coefficients (ICCs) were calculated to evaluate the consistency between sleep parameters obtained from each instrument. Additionally, Bland-Altman plots were used to visually show differences and limits of agreement for sleep parameters measured by PSG, Zmachine, Fitbit, and sleep logs. RESULTS: The findings indicated a moderate agreement between PSG and Zmachine data for total sleep time (ICC=0.46; P<.001), wake after sleep onset (ICC=0.39; P=.002), and sleep efficiency (ICC=0.40; P=.006). In contrast, Fitbit demonstrated notable disagreement with PSG (total sleep time: ICC=0.08; wake after sleep onset: ICC=0.18; sleep efficiency: ICC=0.10) and exhibited particularly large discrepancies from the sleep logs (total sleep time: ICC=-0.01; wake after sleep onset: ICC=0.05; sleep efficiency: ICC=-0.02). Furthermore, subjective and objective concordance among PSG, Zmachine, and sleep logs appeared to be influenced by the severity of the depressive symptoms and obstructive sleep apnea, while these associations were not observed between the Fitbit and other sleep instruments. CONCLUSIONS: Our study results suggest that Fitbit accuracy is reduced in the presence of comorbid clinical symptoms. Although user-friendly, Fitbit has limitations that should be considered when assessing sleep in patients with psychiatric disorders.

Mental Illnesses and Quality of Sleep Among Nurses Working at a Tertiary Hospital in Riyadh During the COVID-19 Pandemic.

Objectives This study primarily aimed to estimate the prevalence of mental illnesses (depression, anxiety, and stress) along with the poor quality of sleep, with a secondary focus on determining whether there was an association between mental health and quality of sleep among nurses working at King Khalid University Hospital, Riyadh, Saudi Arabia, during the COVID-19 pandemic. Methods A cross-sectional study was conducted from June to December 2021 during the COVID-19 pandemic on 309 nurses from different departments at King Khalid University Hospital. Depression, anxiety, and stress were measured by the Depression, Anxiety, and Stress Scale - 21 Items (DASS-21), and sleep quality was measured by the Pittsburg Sleep Quality Index (PSQI) via an online survey. Results The prevalence of depression, anxiety, and stress was 30.4%, 43.7%, and 16.5%, respectively, while 61.5% showed poor sleep quality. The association between poor quality of sleep and the other outcome variables of mental health (depression, anxiety, and stress) was highly significant (p<0.0001). Conclusion Nurses have reported an increased prevalence of depression, anxiety, stress, and poor quality of sleep during the COVID-19 pandemic, making them particularly vulnerable to mental illnesses and sleep difficulties in the event of future pandemics. There is a clear link between mental health issues and poor quality of sleep, necessitating the provision of psychological support for nurses. Enhancing sleep quality is recommended as a way to decrease the prevalence of mental health concerns.

Sleep Quality in Type 2 Diabetes Mellitus Patients Attending a Tertiary Care Hospital in West Bengal: A Cross-Sectional Study.

Background Patients with type 2 Diabetes Mellitus (DM) have a poor quality of life because of various clinical effects. The sleep quality among these patients is affected and they encounter challenges to sleep and wakefulness due to physiological imbalance and co-morbid sleep pathologies. The present study was conducted to ascertain the sleep quality in type 2 DM patients attending a tertiary center in West Bengal. Methodology It was a hospital-based cross-sectional study that was conducted among old/follow-up patients who were suffering from DM. The eligible subjects were selected by systematic random sampling and were interviewed using a semi-structured and pre-tested questionnaire. Information pertaining to socio-demographic characteristics and sleep quality was ascertained. The sleep quality was assessed by using the Pittsburgh Sleep Quality Index (PSQI). Data was analyzed using Statistical Package for Social Sciences (SPSS) version 20 and statistical association of different parameters was tested using Chi-Square test. Results A total of 192 subjects were selected for study. Maximum subjects were above 50 years. A total of 102 males and 90 females participated in the study. A total of 110 subjects were poor sleepers (i.e. PSQI score ≥5) while 82 were good sleepers(PSQI<5). Poor sleepers were maximum in the 20-35 years age group, more in females and unemployed individuals. Subjects with poor diabetes control, i.e. HbA1C more than 7gm/dl were poor sleepers. Conclusions A higher proportion of patients with type 2 DM had poor quality of sleep. It is important on the part of the health personnel to attend to the sleep issues and impaired quality of life due to sleep inadequacy in DM patients.

Unraveling the Nexus: Exploring the Relationship between Exercise Habits and Sleep Quality in Older Adults.

The objective of this study is to investigate the impact of exercise habits on enhancing the sleep quality of older adults. The Pittsburgh Sleep Quality Scale and other questionnaires were utilized to assess the sleep quality of older adults aged 60 years and above in the H district. The sampling method employed was stratified random sampling. To analyze the influencing factors of sleep quality, the average treatment effect was estimated, the robustness of the results was assessed and statistical methods such as Logit regression and propensity score matching were employed. The study revealed that exercise habits strongly correlated with improved sleep quality in the older adult (p < 0.05), with the average total sleep quality score being 6.22 (±3.53). It was observed that older adults who engaged in exercise habits experienced a significant 12.66% increase in the likelihood of achieving good sleep. This investigation highlights the positive association between exercise habits and enhanced sleep quality among older adults. Additionally, age, physical pain and self-rated health statuses were identified as significant factors influencing sleep quality in this population. To enhance the sleep quality of older adults, this article recommends promoting relevant exercise habits, thus contributing to their overall well-being and quality of life.
