Abstract
Although there are many sleep-related complaints in chronic obstructive pulmonary disease (COPD) patients, nocturnal leg cramps have not been adequately and extensively studied. This study fills a significant gap in the literature by determining the prevalence and influencing factors of nocturnal leg cramps in COPD patients. However, our findings also underscore the need for further research, inspiring future studies and interventions in this area. This study was conducted with a rigorous methodology, employing a comprehensive approach to evaluate the probability of experiencing nocturnal leg cramps in 215 COPD and 215 control group patients matched for age and gender. Logistic regression analysis was used, supplemented by artificial neural networks, to identify the influencing factors. This robust methodology ensures the reliability and validity of our findings. The findings of this study are not only significant but also enlightening, shedding light on the prevalence and influencing factors of nocturnal leg cramps in COPD patients. The frequency of experiencing these cramps was found to be 40.9% in chronic obstructive pulmonary patients and 21.9% in the control group (p < .05). In COPD patients, factors such as milk group food consumption, blood erythrocyte level, the cover used while sleeping, blood creatinine level, the presence of coronary artery disease, the diagnosis of diabetes mellitus, the upper mid-arm muscle area, and use of drugs with methylxanthine active ingredient methylxanthine were found to affect the occurrence of these cramps. Our findings not only call for further research but also have immediate practical implications. They highlight the crucial role of nurses in managing nocturnal leg cramps in COPD patients. By controlling patients' cold stress, the bed covers they use, and their dairy product consumption, nurses can significantly contribute to managing these cramps, thereby improving the quality of life for these patients. This underscores the importance of their role in patient care and management.

Abstract
Chronic respiratory disease can exacerbate the normal physiological changes in ventilation observed in healthy individuals during sleep, leading to sleep-disordered breathing, nocturnal hypoventilation, sleep disruption and chronic respiratory failure. Therefore, patients with obesity, slowly and rapidly progressive neuromuscular disease and chronic obstructive airways disease report poor sleep quality. Non-invasive ventilation (NIV) is a complex intervention used to treat sleep-disordered breathing and nocturnal hypoventilation with overnight physiological studies demonstrating improvement in sleep-disordered breathing and nocturnal hypoventilation, and clinical trials demonstrating improved outcomes for patients. However, the impact on subjective and objective sleep quality is dependent on the tools used to measure sleep quality and the patient population. As home NIV becomes more commonly used, there is a need to conduct studies focused on sleep quality, and the relationship between sleep quality and health-related quality of life, in all patient groups, in order to allow the clinician to provide clear patient-centred information.

Abstract
The co-occurrence of obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) in the same patient, named the overlap syndrome (OS), was first described in 1985. Although the American Thoracic Society underlined the limited knowledge of OS, stated research priorities for this condition, and recommended a "screening" strategy to identify OSA in COPD patients with chronic stable hypercapnia, research studies on OS remain scarce. This review aims to summarize the current knowledge and perspectives related to OSA in COPD patients. OS prevalence is 1.0-3.6% in the general population, 3-66% in COPD patients, and 7-55% in OSA patients. OS patients may have worse sleep quality than those with OSA or COPD alone. Scoring hypopneas may be difficult in COPD patients; desaturation episodes may have origins in these patients, namely upper airway obstruction, hypoventilation during paradoxical sleep, ventilation/perfusion mismatches, and obesity. The apnea-hypopnea index is similar in OSA and OS patients. Desaturations may be greater and more prolonged in OS patients than in patients with COPD or OSA alone. Low body mass index, hyperinflation, and less collapsible airways reduce the risk of OSA in COPD patients. OSA is a risk factor for pulmonary hypertension in COPD patients. Whether OS increases mortality and morbidity risks compared to COPD or OSA alone remains to be confirmed. No guidelines currently recommend specific approaches to the treatment of OSA in patients with COPD.

Abstract
Purpose Poor sleep quality and pain were common and had been proved as an important influenced factor of quality of life for patients with COPD. The association of sleep quality with pain has been observed in other population but remains unclear in mild patients with COPD from a community setting. Methods A cross-sectional study was conducted to include eligible mild patients with COPD in Pudong New District of Shanghai. A structured questionnaire was used to collect general and clinical information for the patients. The Chinese version of Pittsburgh Sleep Quality Index (PSQI) and the short form of McGill Pain Questionnaire (SF-MPQ) was used to assess sleep quality and intensity of pain. Logistic regression was performed to test the association between sleeping quality and pain intensity. Results Two hundred and sixty-four patients with COPD, with an average age of 64 years (SD 5.78 years), were enrolled, and of 52% were women. Seventy-one (26.9%) participants reported at least one exacerbation during the past year. About 28.2% of the patients were classified as having poor sleep quality. Sleep quality was significantly associated with PRI score (adjusted odds ratio (ORad)=2.16, 95% CI: 1.16–4.00) and PPI rank (ORad=1.90, 95% CI: 1.08–3.34). People with daytime disturbance were more likely to have pain (ORad =2.03, 95% CI: 1.18–3.50). Conclusion Poor sleep quality was common in mild patients with COPD in community and was associated with higher pain intensity. Pain may involve an impairment of sleep quality.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide, causing substantial economic and social burden. OBJECTIVE This review assessed the patient-reported humanistic burden associated with moderate to very severe COPD, specifically the impact on health-related quality of life (HRQoL), symptoms, limitations in daily life, and emotional implications, through the use of HRQoL instruments. METHODS A systematic review was conducted to retrieve relevant clinical data from published literature using a representative sample of countries where healthcare systems provide wide availability of COPD medications and/or universal coverage includes respiratory medicines (Australia, Canada, China, France, Germany, Italy, Spain, the UK, and the USA). The primary inclusion criteria were patients with moderate to very severe COPD. HRQoL was quantified with non-disease-specific and disease-specific questionnaires. RESULTS In total, 82 studies from 95 publications presented HRQoL data from patients with moderate to very severe COPD. Patient-reported HRQoL declined with worsening airflow limitation, advancing GOLD group, and increasing exacerbation frequency. Both increasing frequency of hospitalization for COPD exacerbations and recurrent hospitalization adversely impacted HRQoL. Comorbidity incidence was higher in patients with increased airflow limitation. It was associated with a further decline in HRQoL and increased depression and anxiety, particularly as disease-associated pain worsened. Physical activity improved HRQoL over time. CONCLUSION This review highlighted the impact of exacerbations and associated hospitalizations on the humanistic burden of COPD. These findings underline the importance of managing COPD actively, including prompt and appropriate use of pharmacological and non-pharmacological therapies that can improve symptoms and reduce the risk of exacerbations, thereby lessening the humanistic burden. Future reviews could consider a broader range of countries and publications to further assess the humanistic impact of COPD in low- and middle-income economies.

Abstract
Objectives This study aimed to determine sleep quality, frequency and severity of dyspnoea in COPD patients and to evaluate the relationship between dyspnoea severity and sleep quality. Method The sample of the study consisted of 110 patients admitted to the Chest Diseases polyclinic of a private hospital and diagnosed as COPD for at least one year. The data of the study were collected using the “Individual Information Form”, “COPD and Asthma Sleep Scale (CASIS)” and “Medical Research Council (MRC) Dyspnoea Scale”. Results It was found that 6.4% of the patients did not experience dyspnoea, 34.5% had mild, 40.9% had moderate, and 18.2% had severe dyspnoea. The mean CASIS score of the patients without dyspnoea was 29.08±7.83, with mild dyspnoea was 40.22±9.30, with moderate dyspnoea was 50.31±8.97 and with severe dyspnoea was 56.96±13.13. There was a statistically significant difference between dyspnoea severity and mean CASIS score (p=0.001). Correlation analysis between MRC dyspnoea scale and CASIS score showed a significant positive correlation (r=0.61 p=0.001). Conclusion It was concluded that the majority of COPD patients had moderate or poor sleep quality and dyspnoea. As dyspnoea severity increases, sleep quality decreases.

Abstract
PURPOSE The association of chronic obstructive pulmonary disease (COPD) severity and related health status with sleep quality remains unclear. We aimed to investigate the association between COPD and sleep quality in the Greek national branch of the UNLOCK cohort. METHODS A sample of 257 COPD patients enrolled cross-sectionally from primary care in Greece. Sleep quality was assessed by the COPD and Asthma Sleep Impact Scale (CASIS-7 items) questionnaire (higher score indicates worse sleep quality). We tested for associations of sleep impairment with health status (CAT and mMRC scores), exacerbations, hospitalizations, GOLD 2018 ABCD status, inhaler adherence, frailty, and sense of coherence, adjusting for age, gender, smoking status, and comorbidities. RESULTS The majority of patients reported uncontrolled symptoms (91% with ≥ 10 CAT or 61% with ≥ 2 mMRC). Mean (SD) age was 65 (12.3) with 79% males. CASIS-7 mean (SD) score was 37.7 (12.9). After adjustments, CASIS was significantly associated with worse health status (e.g., CASIS increased with CAT ≥ 10 [β = 12.53, (95% CI, 6.82, 18.25); p < 0.001], mMRC ≥ 2 [β = 4.96, (95% CI, 1.56, 8.34); p = 0.004]), COPD severity (CAT-based GOLD BD [β = 8.88 (95% CI, 2.50, 15.26); p = 0.007]), frailty [β = 8.85 (95% CI 4.45,13.25); p < 0.001], and sense of coherence [β = -0.14 (95% CI -0.21, -0.06), p < 001]. When using a CASIS cut-off score of 30 as indicator of sleep impairment, additional to the aforementioned associations, we found increased risk for sleep impairment with ≥ 2 exacerbations/year and poor inhaler adherence (p value < 0.05). CONCLUSIONS Our study suggests that worse health status and COPD severity are associated with poor sleep quality in COPD patients.

Abstract
Study Objectives Sleep quality is poor among patients with chronic obstructive pulmonary disease (COPD), and studies show that sleep disturbance is associated with low overall quality of life in this population. We evaluated the impact of patient-reported sleep quality and sleep apnea risk on disease-specific and overall quality of life within patients with COPD enrolled in the SPIROMICS study, after accounting for demographics and COPD disease severity. Methods Baseline data from 1341 participants [892 mild/moderate COPD (FEV1 ≥ 50% predicted); 449 severe COPD (FEV1 < 50%)] were used to perform three nested (blocks) regression models to predict quality of life (Short Form-12 mental and physical components and St. George's Respiratory Questionnaire). Dependent measures used for the nested regressions included the following: Block1: demographics and smoking history; Block 2: disease severity (forced expiratory volume 1 s; 6 min walk test); Block 3: risk for obstructive sleep apnea (OSA; Berlin questionnaire); and Block 4: sleep quality (Pittsburgh Sleep Quality Index [PSQI]). Results Over half of participants with COPD reported poor sleep quality (Mean PSQI 6.4 ± 3.9; 50% with high risk score on the Berlin questionnaire). In all three nested regression models, sleep quality (Block 4) was a significant predictor of poor quality of life, over and above variables included in blocks 1-3. Conclusions Poor sleep quality represents a potentially modifiable risk factor for poor quality of life in patients with COPD, over and above demographics and smoking history, disease severity, and risk for OSA. Improving sleep quality may be an important target for clinical interventions. Clinical Trial SPIROMICS. Clinical Trial URL http://www2.cscc.unc.edu/spiromics/.

Abstract
Background Sleep disturbance has been termed the forgotten dimension of chronic obstructive pulmonary disease (COPD), but it is clinically important as most patients are affected. This study examined the incremental burden of illness associated with sleep disturbance in COPD, with reference to health status and disease impact, and the degree of concordance between physicians and patients in reporting night-time COPD symptoms. Methods Real-world data from >2,500 patients with COPD consulting for routine care were derived from respiratory Disease-Specific Programs conducted in Europe, the USA, and China. Night-time COPD symptom burden was assessed from patient and physician perspectives. Patients completed the Jenkins Sleep Evaluation Questionnaire (JSEQ), COPD assessment test (CAT), and EuroQol five-dimension questionnaire (EQ-5D). A regression approach was used to analyze the relationship between sleep disturbance (JSEQ score) and health status (EQ-5D score), adjusting for confounding variables. Results Frequency of night-time symptoms was high and was higher when reported by patients than physicians (69.7% and 65.7%, respectively). According to the JSEQ, 73.3% of patients had trouble falling asleep, 75.3% experienced night-time awakenings, 70.6% had trouble staying asleep, and 67.7% woke after a usual amount of sleep feeling worn out. Over half (52.7%) of patients received maintenance treatment where night-time symptom relief was stated by the physician as a treatment aim. A one unit increase in JSEQ score was associated with increased CAT score (0.7 units in Europe and the USA; 0.2 units in China). Sleep disturbance was significantly associated with worse health status (odds ratio [OR]: 1.27, 95% confidence interval [CI]: 1.18, 1.36, P<0.001 for Europe; OR: 1.23, 95% CI: 1.12, 1.38, P<0.001 for the USA; and OR: 1.19, 95% CI: 1.10, 1.28, P<0.001 for China). Conclusions Night-time symptoms and sleep disturbance are common among patients with COPD, and sleep disturbance has a detrimental impact on COPD symptoms and health status.

Abstract
Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation that is not fully reversible. It is an incurable disease with improvement in quality of life (QOL) as a major focus area for management. This study assesses the QOL of COPD patients and the factors affecting it. Materials and Methods: All 124 patients diagnosed with COPD in a larger cross-sectional study to determine the prevalence of COPD were assessed for their QOL using St. George's respiratory questionnaire for COPD patients (SGRQ-C). Spirometry was performed to assess lung function and diagnose COPD. Chronic lung disease (CLD) severity index was used to assess the severity of symptoms and the Medical Research Council questionnaire was used to assess the severity of dyspnea. Sociodemographic data regarding the patients were also recorded. Results: Patients with COPD showed significantly reduced health-related quality of life (HRQOL). CLD estimate for severity of lung disease and the Medical Research Council assessment for dyspnea and the duration of illness showed a highly significant positive correlation with HRQOL. There was a statistically significant negative correlation between lung function and SGRQ-C score. Increasing age, increased quantum of smoking, and lower socioeconomic status were correlated with poorer HRQOL. No association between QOL and education, body mass index (BMI), and gender was observed. Conclusion: This study showed that Indian patients with COPD had reduced HRQOL. Poor lung function, increased disease duration and smoking, and worsening symptoms impacted HRQOL negatively.

Abstract
Sleep and circadian disorders in Alzheimer's disease (AD) are more frequent than in the general population and appear early in the course of the disease. Quality of sleep and quality of life are parallel in these patients, and such disorders also represent a heavy burden for caregivers. Although alterations in melatonin and hypocretins (orexins) seem to play a key role in the origin of these disturbances, the etiology of these disorders is multifactorial, including many factors such as environment, behavior, treatments, and comorbidities, among others. A comprehensive evaluation of sleep in each patient is essential in the design of the treatment that includes nonpharmacological and pharmacological approaches. One particularly interesting point is the possibility of a role of sleep disorders in the pathogenesis of AD, raising the possibility that treating the sleep disorder may alter the course of the disease. In this review, we present an update on the role of sleep disorders in AD, the bidirectional influence of sleep problems and AD, and treatment options. Behavioral measures, bright light therapy (BLT), melatonin, and other drugs are likely well known and correctly managed by the physicians in charge of these patients. In spite of the multiple treatments used, evidence of efficacy is scarce and more randomized double-blind placebo-controlled studies are needed. Future directions for treatment are the establishment of BLT protocols and the development of drugs with new mechanisms of action, especially hypocretin receptor antagonists, melatonin receptor agonists, and molecules that modulate the circadian clock.

Abstract
BACKGROUND Adults in intensive care units (ICUs) often suffer from a lack of sleep or frequent sleep disruptions. Non-pharmacological interventions can improve the duration and quality of sleep and decrease the risk of sleep disturbance, delirium, post-traumatic stress disorder (PTSD), and the length of stay in the ICU. However, there is no clear evidence of the effectiveness and harms of different non-pharmacological interventions for sleep promotion in adults admitted to the ICU. OBJECTIVES To assess the efficacy of non-pharmacological interventions for sleep promotion in critically ill adults in the ICU.To establish whether non-pharmacological interventions are safe and clinically effective in improving sleep quality and reducing length of ICU stay in critically ill adults.To establish whether non-pharmacological interventions are cost effective. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL, 2014, Issue 6), MEDLINE (OVID, 1950 to June 2014), EMBASE (1966 to June 2014), CINAHL (Cumulative Index to Nursing and Allied Health Literature, 1982 to June 2014), Institute for Scientific Information (ISI) Web of Science (1956 to June 2014), CAM on PubMed (1966 to June 2014), Alt HealthWatch (1997 to June 2014), PsycINFO (1967 to June 2014), the China Biological Medicine Database (CBM-disc, 1979 to June 2014), and China National Knowledge Infrastructure (CNKI Database, 1999 to June 2014). We also searched the following repositories and registries to June 2014: ProQuest Dissertations & Theses Global, the US National Institutes of Health Ongoing Trials Register (www.clinicaltrials.gov), the metaRegister of Controlled Trials (ISRCTN Register) (www.controlled-trials.com), the Chinese Clinical Trial Registry (www.chictr.org.cn), the Clinical Trials Registry-India (www.ctri.nic.in), the Grey Literature Report from the New York Academy of Medicine Library (www.greylit.org), OpenGrey (www.opengrey.eu), and the World Health Organization International Clinical Trials Registry platform (www.who.int/trialsearch). We handsearched critical care journals and reference lists and contacted relevant experts to identify relevant unpublished data. SELECTION CRITERIA We included all randomized controlled trials (RCT) and quasi-RCTs that evaluated the effects of non-pharmacological interventions for sleep promotion in critically ill adults (aged 18 years and older) during admission to critical care units or ICUs. DATA COLLECTION AND ANALYSIS Two authors independently screened the search results and assessed the risk of bias in selected trials. One author extracted the data and a second checked the data for accuracy and completeness. Where possible, we combined results in meta-analyses using mean differences and standardized mean differences for continuous outcomes and risk ratios for dichotomous outcomes. We used post-test scores in this review. MAIN RESULTS We included 30 trials, with a total of 1569 participants, in this review. We included trials of ventilator mode or type, earplugs or eye masks or both, massage, relaxation interventions, foot baths, music interventions, nursing interventions, valerian acupressure, aromatherapy, and sound masking. Outcomes included objective sleep outcomes, subjective sleep quality and quantity, risk of delirium, participant satisfaction, length of ICU stay, and adverse events. Clinical heterogeneity (e.g., participant population, outcomes measured) and research design limited quantitative synthesis, and only a small number of studies were available for most interventions. The quality of the evidence for an effect of non-pharmacological interventions on any of the outcomes examined was generally low or very low. Only three trials, all of earplugs or eye masks or both, provided data suitable for two separate meta-analyses. These meta-analyses, each of two studies, showed a lower incidence of delirium during ICU stay (risk ratio 0.55, 95% confidence interval (CI) 0.38 to 0.80, P value = 0.002, two studies, 177 participants) and a positive effect of earplugs or eye masks or both on total sleep time (mean difference 2.19 hours, 95% CI 0.41 to 3.96, P value = 0.02, two studies, 116 participants); we rated the quality of the evidence for both of these results as low.There was also some low quality evidence that music (350 participants; four studies) may improve subjective sleep quality and quantity, but we could not pool the data. Similarly, there was some evidence that relaxation techniques, foot massage, acupressure, nursing or social intervention, and sound masking can provide small improvements in various subjective measures of sleep quality and quantity, but the quality of the evidence was low. The effects of non-pharmacological interventions on objective sleep outcomes were inconsistent across 16 studies (we rated the quality of the evidence as very low): the majority of studies relating to the use of earplugs and eye masks found no benefit; results from six trials of ventilator modes suggested that certain ventilator settings might offer benefits over others, although the results of the individual trials did not always agree with each other. Only one study measured length of stay in the ICU and found no significant effect of earplugs plus eye masks. No studies examined the effect of any non-pharmacological intervention on mortality, risk of post-traumatic stress disorder, or cost-effectiveness; the included studies did not clearly report adverse effects, although there was very low quality evidence that ventilator mode influenced the incidence of central apnoeas and patient-ventilator asynchronies. AUTHORS' CONCLUSIONS The quality of existing evidence relating to the use of non-pharmacological interventions for promoting sleep in adults in the ICU was low or very low. We found some evidence that the use of earplugs or eye masks or both may have beneficial effects on sleep and the incidence of delirium in this population, although the quality of the evidence was low. Further high-quality research is needed to strengthen the evidence base.
