Sleep impairment: an obstacle to achieve optimal quality of life in rheumatoid arthritis

Inadequate sleep hygiene as a key factor in poor sleep quality in systemic sclerosis: an observational, cross-sectional study

This study aims to investigate the relationship between sleep hygiene and sleep quality in patients with systemic sclerosis (SSc) and to compare the sleep hygiene and sleep quality outcomes across three distinct groups: SSc patients, rheumatoid arthritis (RA) patients, and healthy controls (HC). This study employed an observational, cross-sectional, and parallel group design. SSc-related and RA-related variables, depression and anxiety were assessed. Physical function and quality of life, pain and fatigue of SSc patients were also evaluated. Sleep quality using the Pittsburg Sleep Quality Index (PSQI) and sleep hygiene using the Sleep Hygiene Index (SHI) were evaluated for all participants. Linear regression analysis was performed to show the relationship between the SHI scores and the other variables. Total PSQI and SHI scores were found to be significantly higher in SSc patients than in RA patients and HC. Fatigue, smoking, all SF-36 domains, depression and anxiety scores were associated with SHI scores in SSc patients. In the univariate logistic regression analysis, SSc patients exhibited 4.50 times higher odds (95% CI 2.165-9.353, p < 0.001) of experiencing poor sleep than RA patients and HC. In SSc patients, for every incremental increase in SHI score, the odds of poor sleep quality were 1.15 times higher (95% CI 1.093-1.220, p < 0.001). Sleep hygiene and sleep quality exhibit a more pronounced deterioration in SSc patients. Inadequate sleep hygiene is associated with compromised sleep quality in SSc. Therefore, improving sleep hygiene practices may be a key strategy to enhance the overall sleep quality in this population.

Sleep disorders in rheumatoid arthritis, axial spondyloarthritis and psoriatic arthritis

Sleep disorders are relatively common among patients with inflammatory arthritis (IA) and have a substantial impact on their quality of life. Although patients frequently recognize poor sleep as an important component of their disease, dyssomnias remain often underdiagnosed and untreated in routine clinical practice. This narrative review examines the prevalence, mechanism, risk factors and management of dyssomnias in rheumatoid arthritis (RA), axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). Relevant articles were retrieved from PUBMED, Scopus and DOAJ. The pathomechanism of sleep disorders in IA is multifactorial and partially differs in RA, axSpA and PsA, however, comparative studies are lacking. Various factors affecting sleep quality, including disease activity, pain, mood disorders, fatigue and female gender, have been examined, but their interplay complicates establishing clear causal relationships. The bidirectional link between sleep quality and rheumatic disease activity highlights the complexity of this issue and demonstrates the importance of holistic management of rheumatic patients. Both pharmacological (e.g., hypnotics, NSAIDs, antidepressants, cannabidiol) and non-pharmacological (e.g., psychotherapy, physical activity) interventions for improving sleep were analyzed. Additionally, questionnaires currently used for assessing sleep were discussed. This review aims to provide a comprehensive overview of sleep disorders across the three most common types of IA, emphasizing the need to develop reliable and patient-friendly tools for everyday clinical practice and further comparative research.

Anxiety and depression as potential risk factors for limited pain management in patients with elderly knee osteoarthritis: a cross-lagged study

BACKGROUND

Pain management for knee osteoarthritis (KOA) patients is challenging. Pain arises from both physiological and psychological interactions, with anxiety and depression potentially contributing as risk factors that hinder effective pain management in KOA patients.

METHODS

Before treatment(T1), A total of 206 elderly inpatients with KOA were enrolled based on initial screening criteria. After treatment (T2), patients were selected based on inclusion and exclusion criteria, and completed follow-up through phone or online questionnaires. The interval between T1 and T2 was three months. Outcome measures included the Visual Analogue Scale (VAS) for pain intensity, Beck Anxiety Inventory (BAI) for anxiety, and Geriatric Depression Scale (GDS) for depression. Descriptive and bivariate analyses were used to evaluate the pain, anxiety and depression of the participants. A cross-lagged model was used to examine the temporal and causal associations among pain, anxiety, and depression.

RESULTS

91% of elderly patients with KOA experienced at least mild depression. Furthermore, 31% of patients reported mild or higher levels of anxiety. At the same time, pain, depression, and anxiety were significantly correlated and mutually predictive(all p < 0.01). Across the different time points, Depression and anxiety at T1 positively predicted pain at T2,with correlation coefficients of 0.19 (p < 0.05) and 0.07 (p < 0.05), respectively.

CONCLUSIONS

Anxiety and depression may be potential risk factors limiting the effectiveness of pain management in KOA patients. Clinical treatment should regularly evaluate anxiety and depression levels and integration of psychological interventions or appropriate antianxiety and antidepressant medications.

Sleep Deprivation in Healthy Males Increases Muscle Afferents, Impairing Motor Preparation and Reducing Endurance

PURPOSE

Sleep deprivation (SD) reduces time to task failure during endurance exercises. The aim of our work was to study the effect of acute SD on the endurance of a skeletal hand muscle and to investigate cortical motor drive to muscle and perception of effort.

METHODS

Origin of the early exhaustion after SD might be insufficient cortical motor drive to muscle or motor inhibition because of excessive perception of effort. The supplementary motor area, the medial part of the premotor cortex, links the motor and sensory cortexes, prepares for voluntary movements, and may play a central role in the pathophysiology of impaired muscle endurance after SD. Supplementary motor area can be noninvasively assessed by electromyogram measuring amplitude of premotor potentials before hand movements. We investigated the effect of SD on muscle endurance in healthy volunteers performing moderate hand exercise by monitoring supplementary motor area activation and muscle afferents. Two sessions were performed, in random order, one after a normal sleep night and the other after a sleepless night.

RESULTS

Twenty healthy young men were included in this study. Sleep deprivation reduced time to task failure by 11%. Supplementary motor area activation was altered throughout the task and effort perception was increased.

CONCLUSIONS

Our results suggest that SD reduces skeletal muscle endurance by increasing the effects of muscle afferents on the supplementary motor area. Sleep alterations frequently reported in chronic diseases might reduce patients' capacity to achieve the low-intensity motor exercises required in everyday life. Our results should lead to the search for sleep disorders in patients with chronic pathology.

Effectiveness of the re-engineered discharge (RED) care model in patients with rheumatoid arthritis

This study aims to investigate whether the re-engineered discharge (RED) model can significantly improve the quality of life, enhance the health status, and reduce the levels of depression and anxiety in patients with rheumatoid arthritis during hospitalization. This study selected 108 rheumatoid arthritis patients treated at our facility between February 2023 and February 2024. Based on the different treatment methods, these patients were divided into a control group and an observation group, with 54 patients in each group. During hospitalization, both groups received standardized routine care provided by the hospital. After discharge, the control group continued with regular follow-up visits, while the observation group received a more comprehensive and multidimensional extended care based on the RED model. The intervention period for both groups was set to 3 months. The core observation indicators of this study focused on the emotional fluctuations, symptom improvement, and changes in self-care ability of the patients before and after the intervention. After the intervention, the scores of the Self-Rating Anxiety Scale and Self-Rating Depression Scale in both groups showed significant decreases, with the scores in the observation group being significantly lower than those in the control group, showing a highly significant statistical difference (P < .01). Additionally, the joint pain scores in both groups were alleviated, reflected by shorter morning stiffness times, reduced joint swelling, and increased grip strength. The observation group had lower joint pain scores, shorter morning stiffness times, fewer swollen joints, and stronger grip strength, all of which were statistically significant (P < .01). Furthermore, the distribution of self-care abilities in the observation group showed a significant difference compared to the control group (P < .05), with the observation group having a higher proportion of self-care abilities, which was also statistically significant (P < .05). For patients with rheumatoid arthritis, the implementation of the RED model nursing strategy can significantly alleviate negative emotions, reduce the distress caused by symptoms, and markedly improve their quality of life, providing a more comfortable and reassuring treatment experience.

Exploration in association between vitamin D, sleep quality, and osteoarthritis: A modeling study

Previous studies on the relationship between vitamin D, sleep quality, and osteoarthritis (OA) have been controversial and the aim of this study is to analyze the association. In this study, relevant data from 2 survey cycles (2009-2010 with 2011-2012) are downloaded from the CDC's NHANES project to analyze the relationship between vitamin D, sleep quality, and osteoarthritis, as well as other related risk factors. The analysis of statistics in this study is performed using t-tests and chi-square tests, modeling is performed using logistic regression based on NHANES weights, and other risk factors are analyzed using forest plots. In association models between serum vitamin D, sleep quality, and OA is statistically significant during the stepwise inclusion of covariates. In model 1, Q3 (OR = 1.83; 95% CI: 1.05, 3.23) and Q4 (OR = 2.22; 95% CI: 1.27, 3.94) are significant. Neither model 2 nor model 3 is statistically significant and P for trend is more than .05 in all 3 models. After the inclusion of all covariates, forest plot showed that sleep deprivation (OR = 1.64; 95% CI: 1.05, 2.56), advanced age (OR = 1.03; 95% CI: 1.01, 1.04), female (OR = 1.79; 95% CI: 1.14, 2.85), overweight (25 ≤ BMI < 30) (OR = 1.92; 95% CI: 1.05, 3.61), and obesity (≥30) (OR = 2.06; 95% CI: 1.11, 3.93) are risk factors for OA. This study is based on a larger sample and a stepwise logistic regression of multiple covariates. We concluded that vitamin D may not influence OA. However other risk factors for OA are confirmed, including advanced age, female and high BMI, especially bad sleep quality.

Tailoring Strength Training Prescriptions for People with Rheumatoid Arthritis: A Scoping Review

Introduction: Prescribing strength training (ST) for people with rheumatoid arthritis (RA) is complicated by factors (barriers and facilitators) that affect participation. It is unclear whether guidelines include recommendations beyond prescription parameters (frequency, intensity, time, type, volume, and progression) and adequately incorporate participation factors tailored to people with RA. Objective: To summarize available recommendations to aid in the tailoring of ST prescriptions for people with RA. Methods: Medline, Embase, and CINAHL databases and gray literature were searched for guidelines, recommendations, and review articles containing ST prescription recommendations for RA. Article screening and data extraction were performed in duplicate by two reviewers. Results: Twenty-seven articles met the inclusion criteria. The recommendations address RA-specific ST participation factors including: knowledge gaps (of equipment, ST benefits, disease), memory problems, the management of joint deformity, comorbidity, the fluctuating nature of the disease and symptoms (pain, stiffness, flares), fear avoidance, motivation, need for referral to other professionals, and provision of RA-specific resources. Conclusion: This review summarizes recommendations for tailoring ST prescriptions for people with RA. Future research is required to understand how pain, symptom assessment, and unaddressed ST participation factors like sleep and medication side effects can be addressed to support ST participation amongst people with RA.

A concept elicitation study to understand the relationship between sleep and pain in rheumatoid arthritis and axial spondyloarthritis

PURPOSE

This qualitative study (GSK study: 213635) was designed to better understand sleep disturbance as experienced by individuals with rheumatoid arthritis (RA) or axial spondyloarthritis (axSpA), and the relationship between sleep disturbance and pain and other aspects of the disease and disease activity.

METHODS

Sixty-minute, one-on-one, concept elicitation interviews were conducted with 30 participants (15 with RA and 15 with axSpA) from the US. Interviews were audio-recorded and transcribed verbatim. Interview transcripts were coded and analyzed to explore themes related to pain and sleep disturbance, and relationships among those themes.

RESULTS

Pain was a prominent driver of sleep disturbance; 12 participants with RA (80%) and 14 with axSpA (93%) reported that pain impacted their ability to fall asleep, while all 15 with RA (100%) and 14 with axSpA (93%) reported that pain impacted their ability to stay asleep. Two-thirds of participants with RA (67%) or axSpA (60%) described a bi-directional relationship, whereby pain worsened sleep disturbance and sleep disturbance further aggravated pain. Factors other than pain, such as fatigue and emotional health, were also reported as important contributors to sleep disturbance (RA: n = 12/15, 80%; axSpA: n = 14/15, 93%). Participants with RA or axSpA described complex interconnections between fatigue, emotional health, pain, and sleep, often labeling these relationships as "vicious cycles". Notably, half of all participants reported sleep disturbance occurring without pain or other understood causes.

CONCLUSION

These perspectives collected from people with RA or axSpA suggest that reducing sleep disruption directly may offer clinically relevant benefits.

Research progress of targeted therapy regulating Th17/Treg balance in bone immune diseases

Rheumatoid arthritis (RA) and postmenopausal osteoporosis (PMOP) are common bone-immune diseases. The imbalance between helper (Th17) and regulatory T cells (Tregs) produced during differentiation of CD4+ T cells plays a key regulatory role in bone remodelling disorders in RA and PMOP. However, the specific regulatory mechanism of this imbalance in bone remodelling in RA and PMOP has not been clarified. Identifying the regulatory mechanism underlying the Th17/Treg imbalance in RA and PMOP during bone remodelling represents a key factor in the research and development of new drugs for bone immune diseases. In this review, the potential roles of Th17, Treg, and Th17/Treg imbalance in regulating bone remodelling in RA and PMOP have been summarised, and the potential mechanisms by which probiotics, traditional Chinese medicine compounds, and monomers maintain bone remodelling by regulating the Th17/Treg balance are expounded. The maintenance of Th17/Treg balance could be considered as an therapeutic alternative for the treatment of RA and PMOP. This study also summarizes the advantages and disadvantages of conventional treatments and the quality of life and rehabilitation of patients with RA and PMOP. The findings presented her will provide a better understanding of the close relationship between bone immunity and bone remodelling in chronic bone diseases and new ideas for future research, prevention, and treatment of bone immune diseases.

'I never thought exercise could help improve my sleep': experiences of people with rheumatoid arthritis on the impact of an 8-week walking-based exercise intervention in improving their sleep

Objective

The purpose of this study was to explore the experiences of people with RA of participating in an exercise intervention to improve their sleep.

Methods

Using a qualitative descriptive design, semi-structured face-to-face interviews were conducted with 12 people with RA who had completed an 8-week walking-based exercise intervention to improve their total sleep time, sleep quality and sleep disturbance. Data were analysed using thematic analysis.

Results

Four themes were generated: positive impact of exercise on participants' sleep ('I really didn't think any type of exercise would help me sleep better, if I'm honest'); positive experiences of the exercise intervention ('I learnt so much regarding walking that I didn't even think about'); clear mental health benefits ('If you don't sleep well then it will have a knock-on effect to your mental health'); and achieving empowerment and ownership when exercising ('I feel empowered now and confident that I'm not doing harm to myself').

Conclusion

The findings demonstrated that participants had not expected exercise to improve their sleep. Although there is a growing consensus that exercise will benefit sleep and mitigate some disease symptoms, research is severely lacking in people with RA.

Exercise therapy for improving cardiovascular health in rheumatoid arthritis

There is increased risk of cardiovascular disease in patients with rheumatoid arthritis. Primary cardiovascular disease prevention in rheumatoid arthritis patients is difficult, especially in those with high disease activity. According to current evidence, people with rheumatoid arthritis can significantly improve clinical indices and patient-reported outcomes by engaging in organized physical activity such as resistance training and aerobic activities. Additionally, participating in an exercise regimen can lower the risk of experiencing cardiovascular problems. Nevertheless, the percentage of patients with sedentary lifestyle habits is high among individuals with rheumatoid arthritis. Patient education regarding the benefits of physical activity/exercise is essential. The cardiovascular effects of exercise depend on several mechanisms such as (i) increased vascular function, (ii) decreased systemic inflammation, (iii) restoration of the autonomic system, (iv) improved lipid profile, and (v) increased muscular function. Maintaining the exercise routine is crucial for continuing benefits. A customized exercise plan helps to improve adherence and compliance. Engaging patients in shared decision-making is important since their personal choices can alter depending on several factors such as the severity of the disease, the cost, and accessibility. The current narrative review aimed to explore the recent evidence related to exercise therapy for cardiovascular health in patients with rheumatoid arthritis.

Detecting and exploiting the circadian clock in rheumatoid arthritis

Over the past four decades, research on 24-h rhythms has yielded numerous remarkable findings, revealing their genetic, molecular, and physiological significance for immunity and various diseases. Thus, circadian rhythms are of fundamental importance to mammals, as their disruption and misalignment have been associated with many diseases and the abnormal functioning of many physiological processes. In this article, we provide a brief overview of the molecular regulation of 24-h rhythms, their importance for immunity, the deleterious effects of misalignment, the link between such pathological rhythms and rheumatoid arthritis (RA), and the potential exploitation of chronobiological rhythms for the chronotherapy of inflammatory autoimmune diseases, using RA as an example.

Prevalence of Poor Sleep Quality and Associated Factors in Individuals with Rheumatoid Arthritis: A Cross-Sectional Study

Background and Objectives: Poor sleep quality has been frequently observed in individuals with rheumatoid arthritis. In the present study, we analyzed the presence of poor sleep quality in a sample of Mexican individuals with rheumatoid arthritis; then, we compared sociodemographic and clinical characteristics among patients to determine risk factors for poor sleep quality. Materials and Methods: In this cross-sectional study, we included 102 individuals with rheumatoid arthritis from a hospital in Mexico. We evaluated disease activity (DAS28), quality of sleep using the Pittsburgh Sleep Quality Index, and the presence of depression and anxiety with the Hospital Anxiety and Depression Scale. We performed a Chi-square test and a t-test. Then, we performed a logistic regressions model of the associated features in a univariable analysis. Results: Poor sleep quality was observed in 41.75% of the individuals with rheumatoid arthritis. Being married was a proactive factor (OR 0.04, 95% CI 0.1-0.9, p = 0.04), whereas having one's hips affected or presenting with anxiety and depression was associated with poor sleep quality (OR 4.6, 95% CI 1.2-17.69, p = 0.02). After a multivariate analysis, having anxiety (OR 5.0, 95% CI 1.4-17.7, p < 0.01) and depression (OR 9.2, 95% CI 1.0-8.1, p < 0.01) remained associated with a higher risk of having poor sleep quality. Other clinical characteristics among patients were not significantly different. Conclusions: Our results showed that individuals with rheumatoid arthritis who also presented with depression or anxiety had a higher risk of suffering from poor sleep quality. However, more studies with larger samples are necessary to replicate these results in the Mexican population.

Biopsychosocial factors should be considered when evaluating central sensitization in axial spondyloarthritis

To identify the determinants of central sensitization (CS) in patients with axial spondyloarthritis (axSpA). Central Sensitization Inventory (CSI) was used to determine CS frequency. Disease-related variables including Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score (ASDAS-CRP/-ESR), Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), Bath Ankylosing Spondylitis Functional Index (BASFI), Ankylosing Spondylitis Quality of Life Questionnaire (ASQoL) and Numeric Rating Scale (NRS)GLOBAL were assessed. Biopsychosocial variables were evaluated by the Multidimensional Scale of Perceived Social Support (MSPSS), Brief Illness Perception Questionnaire (B-IPQ), Hospital Anxiety and Depression Scale (HADS) and subscales for Anxiety (HADS-A) and Depression (HADS-D), and Jenkins Sleep Evaluation Scale (JSS). To determine the predictors of the development and severity of CS, multiple linear and logistic regression analyses were performed. The frequency of CS was 57.4% in the study population (n = 108). CSI score was correlated with the duration of morning stiffness, BASDAI, ASDAS-CRP, ASDAS-ESR, NRSGLOBAL, BASFI, MASES, ASOoL, JSS, HADS, and B-IPQ total scores (ρ ranged from 0.510 to 0.853). Multiple regression analysis indicated that BASDAI (OR: 10.44, 95% CI: 2.65-41.09), MASES (OR: 2.47, 95% CI: 1.09-5.56) and HADS-A (OR: 1.62, 95% CI: 1.11-2.37) were independent predictors of the development of CS. Additionally, higher NRSGLOBAL, JSS, HADS-D, and HADS-A scores appeared to determine the severity of CS. This study confirms that worse disease activity, more enthesal involvement, and anxiety independently predict the development of CS. Additionally, higher patient-perceived disease activity, sleep impairment and poor mental health significantly contribute to the severity of CS.

The Effects of Self-Aromatherapy Massage on Pain and Sleep Quality in Patients with Rheumatoid Arthritis: A Randomized Controlled Trial

BACKGROUND

Rheumatoid arthritis is the most common form of inflammatory arthritis and can lead to pain, joint deformity, and disability, resulting in poor sleep quality and lower quality of life. The efficacy of aromatherapy massage on pain levels and sleep quality among rheumatoid arthritis patients remains unclear.

AIMS

To investigate the effects of aromatherapy on pain and sleep quality among rheumatoid arthritis patients.

METHODS

This randomized controlled trial enrolled 102 patients with rheumatoid arthritis from one regional hospital in Taoyuan, Taiwan. Patients were randomly assigned to the intervention (n = 32), placebo (n = 36), or control groups (n = 34). The intervention and placebo groups underwent self-aromatherapy hand massage guided by a self-aromatherapy hand massage manual and video for 10 minutes 3 times a week for 3 weeks. The intervention group used 5% compound essential oils, the placebo group used sweet almond oil, and the control group had no intervention. Pain, sleep quality and sleepiness were measured by using the numerical rating scale for pain, the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale at baseline and at 1, 2, and 3 weeks after the intervention.

RESULTS

The intervention and placebo groups had significantly decreased sleep quality and sleepiness scores from baseline to 3 weeks after aromatherapy massage. Compared with the control group, the intervention group showed statistically significant improvement in the sleep quality scores in the first weeks after aromatherapy massage (B = -1.19, 95% confidence interval [CI]: -2.35, -0.02, P =.046), but no statistically significant differences were found in the changes in pain levels from baseline to the three time points.

CONCLUSIONS

Aromatherapy massage is effective in improving sleep quality in rheumatoid arthritis patients. More studies are needed to evaluate the effects of aromatherapy hand massage on the pain levels of rheumatoid arthritis patients.

Development and validation of an ama instrument for assessing the disease activity on the basis of constitutional features in Amavata (Rheumatoid Arthritis)

BACKGROUND

Rheumatoid Arthritis (RA), having a striking clinical resemblance to amavata in traditional Indian medicine (Ayurveda) presents an opportunity to look at disease from two different healthcare perspectives. This differential information may potentially supplement one system with the knowledge of the other for optimal application. This study is the first of its kind, where Ayurvedic concepts of amavata have been adopted to enhance the knowledge about RA where optimal care is still beyond the common reach.

OBJECTIVE

The study was conducted to develop and validate a novel ama score based upon constitutional features of ama as depicted in ayurvedic literature as a disease activity indicator in RA.

MATERIAL AND METHODS

The study was conducted in two parts comprising development and textual validation of the ama assessment instrument (AAI) followed by its clinical testing. AAI comprising ten items, was developed where each item was provided with a range of scores to offer the assessment close to the patient's observations. The score obtained through AAI was clinically and statistically tested on 79 RA/amavata patients randomly selected for validity and reliability. The score obtained through AAI was tested for its correlation with the DAS-28 score and ESR.

RESULTS

Ama Assessment Instrument could find a slight correlation with acute phase reactant ESR (r-value between ESR and AMA at baseline is 0.287, and at 1st, 2nd, and 3rd follow-up is 0.276, 0.276 and 0.160 respectively) and DAS-28 (The r value between DAS and AMA at baseline is 0.231, and at 1st, 2nd and 3rd follow up is 0.218, 0.201 and 0.247 respectively). It however emerged as an independent disease status marker since it could mark the changes in the study population on a time scale more precisely as compared to DAS -28 or ESR. When the ama values at different follow-ups were compared, a significant difference was observed consistent with disease activity marker catching constitutional and GI related domain of the patients. When reducing values of ama score were compared to overall improvements as reported by the patients, a similar trend was observed showing that a change in ama score is reflective of a change in disease status and the impact of the disease on the patient.

CONCLUSION

This study provided a quantitative measure for the abstract concept of ama which could be used to mark the disease activity in amavata or RA. The change in ama based scores can be used to assess disease status and the intervention related benefits. The observations prompt for the possible inclusion of AAI in RA composite score to make it more dynamic in terms of disease activity identification in RA.

Workplace barriers among people with rheumatic and chronic back pain: Results from the work experience survey for rheumatic conditions

BACKGROUND

The Work Experience Survey for Rheumatic Conditions (WES-RC) is a prominent feature of an evidence-based intervention to prevent premature job loss among people with arthritis. The WES-RC is used to identify client perceived barriers related to work performance. The degree to which people with arthritis and rheumatic conditions report barriers on the WES-RC has not been reported.

OBJECTIVE

The purpose of this study was to characterize the barriers reported on the WES-RC.

METHODS

Data from participants who completed the WES-RC in the Work It study trial were included (N = 143). Descriptive statistics were used to characterize the sample and the frequency with which barriers on the WES-RC were reported. Responses to the top three bothersome barriers to study participants were summed.

RESULTS

The mean age of the sample was 50.3 years; 73% were female, and 66% white. All WES-RC items were checked as a barrier by at least two participants; less than 10 participants checked 34 items. Barriers in the 'getting ready for work and traveling to and from, or for work' domain, were frequently reported. The most bothersome barriers were 'standing or being on feet too long' and 'prolonged sitting'.

CONCLUSION

The WES-RC is a self-reported checklist that captures a wide breadth of work-related barriers that could be experienced by people with arthritis who are currently employed.

Subjective sleep quality and fatigue assessment in Polish adult patients with primary immunodeficiencies: A pilot study

Introduction

Primary immunodeficiencies (PIDs) are clinically heterogeneous disorders caused by abnormalities in the immune system. However, PIDs are genetically determined and may occur at any age from early childhood to elderly age. Due to chronic patterns, the risk of malignancy and organ damage in patients with PIDs may affect any aspect of life, including sleep patterns. To our knowledge, the prevalence of insomnia and subjective sleep quality have not been investigated in patients with PIDs. Therefore, this pilot study was conducted to investigate sleep quality, the prevalence of sleep disturbances, and fatigue in adult patients with PIDs in Poland.

Methods

All participants were surveyed using the Athens Insomnia Scale, Pittsburgh Sleep Quality Index, Fatigue Severity Scale, and a questionnaire concerning general health and demographic data. We included 92 participants: 48 women (52.2%) and 44 men (47.8%).

Results

Participants' mean age was 41.9 ± 13.9 years. The mean sleep duration was 7.0 ± 1.5 hours, and the mean sleep latency was 41.2 ± 53.1 minutes. Additionally, 44.6% of patients (n=41) had symptoms of insomnia and 44.6% (n=42) had poor sleep quality. Less than one-fourth (n=22; 23.9%) of the patients reported the use of sleeping pills; moreover, clinically significant fatigue was reported in 52.2% (n=48).

Discussion

Our investigation provides insight into the problem of sleep disturbances in patients with PIDs. Data have demonstrated that sleeping disorders with concomitant fatigue are common in patients with PID. Further studies are needed to determine the determinants of poor sleep quality in this specific group of patients.

Sleep disturbances in chronic rheumatic diseases: Is disease activity the major determinant factor?

INTRODUCTION

Sleep disturbances are closely related to chronic pain processes, especially in patients with inflammatory and mechanical joint diseases.

OBJECTIVES

This study aims to report sleep characteristics in patients with rheumatoid arthritis (RA) and knee osteoarthritis also to determine the responsibility of disease activity in the occurrence of sleep disturbances during chronic rheumatic diseases.

METHODS

We conducted a comparative study between two groups of patients: the first with RA, the second with primary knee osteoarthritis. We reported sociodemographic and medical data (clinical and biological inflammatory syndrome data). Then, we assessed depression, anxiety, and sleep disturbances with respectively Beck Depression Inventory, Beck Anxiety Inventory and Medical Outcome Study Sleep Scale (MOS-SS).

RESULTS

Seventy RA patients aged 51.9 years, with an average of 77.1% female were studied. The mean disease duration was 6.9 years. All sleep domains were altered in these patients. Forty patients with knee osteoarthritis aged 57.5 years with an average of 70% female were included. The mean disease duration was 4 years. The most impaired domains in this group were somnolence and sleep disturbance. Multivariate analysis concluded that risk factors independently related to RA were:  disease activity score, functional disability, depression, anxiety, and body mass index. Disease activity score were the only parameter to influence all domains of sleep.

CONCLUSION

So we result that disease activity is a risk factor independently related to sleep disturbances in rheumatoid arthritis. Furthermore, mood disorders and obesity also deteriorate several sleep domains. These factors must be considered in the management of chronic rheumatic disorders.

Association of lifestyle and disease characteristics with self-rated wellness/health score in patients with rheumatoid arthritis

Objective

To study the relationship of self-rated wellness/health and lifestyle in patients with rheumatoid arthritis.

Methods

Self-rated wellness/health, demographics, smoking, mood, sleep, physical activity, diet, symptoms/signs, body mass index and laboratory findings in 142 patients with rheumatoid arthritis were collected in the current cross-sectional study. Multivariable generalized additive model (GAM) was employed to study the association of self-rated wellness/health score and lifestyle factors.

Results

Female/male ratio was 116/26 and the mean (SD) age of sample was 52 (13) years. Mean (SD) self-rated wellness/health score out of 10 was 7.2 (1.63). Mean (SD) number of tender joints and swollen joints were 4.42 (4.55) and 4.00 (4.26), respectively. The mean sleep score was 29.5 out of 70. Patients went to bed more than one hour earlier during the weekdays compared to weekends (22:45 vs. 23:52 PM, respectively, p < 0.0001). They also woke up more than one hour earlier during the weekdays compared to the weekends (6:08 vs. 7:20 AM, respectively, p < 0.0001). Their nap duration during weekdays was about half an hour shorter than the nap duration on weekends (19.75 vs. 48.02 minutes, respectively, p < 0.0001). The mean mood and diet scores were 18.5/35 and 22.5/42, respectively. By backward elimination in multivariable regression model (GAM), disease duration, mood, sleep quality, weekdays sleep characteristics (sleep duration, time to go to bed, wake-up time, time to fall asleep and nap duration), and sleep duration on weekends remained in the final model (R² = 0.225, p = 0.01). Sleep quality, nap duration on weekdays, night sleep duration on weekends and mood status were the significant variables associated with self-rated wellness/health score.

Conclusion

In patients with rheumatoid arthritis, the low self-rated wellness/health score was associated with the low sleep quality, long sleep duration on weekends, and long nap duration on weekdays.

Developing a Novel Measurement of Sleep in Rheumatoid Arthritis: Study Proposal for Approach and Considerations

The development of novel digital endpoints (NDEs) using digital health technologies (DHTs) may provide opportunities to transform drug development. It requires a multidisciplinary, multi-study approach with strategic planning and a regulatory-guided pathway to achieve regulatory and clinical acceptance. Many NDEs have been explored; however, success has been limited. To advance industry use of NDEs to support drug development, we outline a theoretical, methodological study as a use-case proposal to describe the process and considerations when developing and obtaining regulatory acceptance for an NDE to assess sleep in patients with rheumatoid arthritis (RA). RA patients often suffer joint pain, fatigue, and sleep disturbances (SDs). Although many researchers have investigated the mobility of joint functions using wearable technologies, the research of SD in RA has been limited due to the availability of suitable technologies. We proposed measuring the improvement of sleep as the novel endpoint for an anti-TNF therapy and described the meaningfulness of the measure, considerations of tool selection, and the design of clinical validation. The recommendations from the FDA patient-focused drug development guidance, the Clinical Trials Transformation Initiative (CTTI) pathway for developing novel endpoints from DHTs, and the V3 framework developed by the Digital Medicine Society (DiMe) have been incorporated in the proposal. Regulatory strategy and engagement pathways are also discussed.

Cross-sectional assessment of sleep and fatigue in middle-aged Japanese women with primary Sjogren syndrome or rheumatoid arthritis using self-reports and wrist actigraphy

ABSTRACT

To investigate fatigue, health-related quality of life (HR-QOL), and sleep quality in women with primary Sjogren syndrome (pSS) or rheumatoid arthritis (RA) as compared with healthy controls using self-reports and wrist actigraphy.In this cross-sectional observational study, we evaluated a total of 25 patients (aged 40-75 years) with pSS, 10 with RA, and 17 healthy control subjects living in Japan. The HR-QOL was assessed using the Short Form-36. Fatigue was evaluated using the Short Form-36 vitality score, visual analog scale (VAS) for fatigue, and 2 questionnaire items using scores based on a 4-point Likert scale. Sleep quality was measured using the Japanese version of the Pittsburgh Sleep Quality Index, VAS for sleep quality, and wrist actigraphy for 14 days.Patients with pSS reported severer fatigue and lower HR-QOL than healthy controls, especially in mental health. Based on the Pittsburgh Sleep Quality Index score, 56% of the patients with pSS were poor sleepers, which was higher than healthy controls (29.4%). Furthermore, the patients with pSS scored significantly lower on the VAS for sleep quality than healthy controls (40.5 vs 63.7, P = .001). Although subjective assessments revealed slight sleep disturbances in patients with pSS, wrist actigraphy revealed no differences when compared with healthy controls for total sleep time (421.8 minutes vs 426.5 minutes), sleep efficiency (95.2% vs 96.4%), number of awakenings (1.4 vs 0.9), and wake after sleep onset (22.4 minutes vs 16.1 minutes). Poor subjective sleep quality was associated with enhanced fatigue. However, sleep efficiency, as determined by actigraphy, was not associated with fatigue. Notably, the patients with RA and healthy controls did not differ significantly in terms of fatigue or sleep quality, although patients with RA experienced more nocturnal awakenings than healthy controls (1.7 vs 0.9, P = .04).Patients with pSS experience severe fatigue, poor HR-QOL, and sleep disturbances, which are associated with fatigue. However, wrist actigraphy did not reveal differences in sleep quality, suggesting that it may not be an appropriate measure of sleep in patients with pSS.

Effects of illness perceptions on health-related quality of life in patients with rheumatoid arthritis in China

Objectives

For patients with rheumatoid arthritis (RA) in China, little is known of how their illness perceptions affect their health-related quality of life (HRQoL). The present study investigated associations between specific illness perceptions due to RA and HRQoL features.

Methods

For 191 patients with RA, illness perceptions were measured using the Brief Illness Perceptions Questionnaire (BIPQ) comprising 8 domains. HRQoL was determined with the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Multivariate linear regression analyses were performed.

Results

The overall BIPQ of patients with RA was 49.09 ± 11.06. The highest and lowest scores were for concern (9.15 ± 1.81) and personal control (4.30 ± 2.52), respectively. Multivariate stepwise regression analyses showed that the overall BIPQ was significantly negatively associated with each HRQoL feature, and HRQoL total score (β = − 0.343, P < 0.001, 95% CI − 7.080 to − 4.077). Positive associations between BIPQ features and HRQoL included personal control (β = 0.119, P = 0.004, 95% CI 2.857–14.194) and treatment control (β = 0.084, P = 0.029, 95% CI 0.640–12.391). Negative associations with HRQoL were identity (β = − 0.105, P = 0.034, 95% CI − 13.159 to − 0.430) and emotional response (β = − 0.207, P < 0.001, 95% CI − 18.334 to − 6.811).

Conclusions

Patients with RA in China perceive their illness in ways that affect their HRQoL. These results suggest that strategies that target these perceptions may improve the quality of life of these patients.

microRNA-23 inhibits inflammation to alleviate rheumatoid arthritis via regulating CXCL12

Rheumatoid arthritis (RA) is a common systemic, inflammatory and autoimmune disorder. MicroRNAs (miRs) are strongly associated with the initiation and progression of RA. However, the functions and mechanisms underlying miR-23 in RA are not completely understood. Therefore, the present study aimed to investigate the molecular mechanisms underlying miR-23 in RA. A bioinformatics tool (StarBase) and a wide range of experimental assays, including reverse transcription-quantitative PCR, western blotting, luciferase reporter assays and ELISAs, were performed to investigate the biological role of miR-23 in RA. The results indicated that miR-23 was downregulated and chemokine C-X-C motif ligand 12 (CXCL12) was upregulated in RA samples compared with healthy samples. Furthermore, miR-23 overexpression suppressed inflammation via reducing TNF-α, IL-1β and IL-8 expression levels compared with the NC mimic group. Regarding the underlying mechanism, compared with NC mimic, miR-23 mimic decreased CXCL12 mRNA expression by binding to its 3'-untranslated region. Additionally, CXCL12 overexpression reversed miR-23 mimic-mediated effects on inflammation. NF-κB signaling is associated with inflammation. Therefore, the present study indicated that CXCL12 promoted inflammation by activating NF-κB signaling. In conclusion, miR-23 inhibited inflammation to alleviate RA by regulating CXCL12 via the NF-κB signaling pathway, which may serve as a potential target for the diagnosis and treatment of RA.

Isotemporal Substitution of Time Between Sleep and Physical Activity: Associations With Cardiovascular Risk Factors in Early Rheumatoid Arthritis

OBJECTIVE

We aimed to determine relationships between objectively measured nightly sleep, sedentary behavior (SB), light physical activity (LPA), and moderate to vigorous physical activity (MVPA) with risk factors for cardiovascular disease (CVD) in patients with early rheumatoid arthritis (RA). Furthermore, we aimed to estimate consequences for these risk factors of theoretical displacements of 30 minutes per day in one behavior with the same duration of time in another.

METHODS

This cross-sectional study included 78 patients with early RA. Nightly sleep, SB, LPA, and MVPA were assessed by a combined heart rate and accelerometer monitor. Associations with risk factors for CVD were analyzed using linear regression models and consequences of reallocating time between the behaviors by isotemporal substitution modeling.

RESULTS

Median (Q1-Q3) nightly sleep duration was 4.6 (3.6-5.8) hours. Adjusted for monitor wear time, age, and sex, 30-minutes-longer sleep duration was associated with favorable changes in the values β (95% confidence interval [CI]) for waist circumference by -2.2 (-3.5, -0.9) cm, body mass index (BMI) by -0.9 (-1.4, -0.4) kg/m2 , body fat by -1.5 (-2.3, -0.8)%, fat-free mass by 1.6 (0.8, 2.3)%, sleeping heart rate by -0.8 (-1.5, -0.1) beats per minute, and systolic blood pressure by -2.5 (-4.0, -1.0) mm Hg. Thirty-minute decreases in SB, LPA, or MVPA replaced with increased sleep was associated with decreased android fat and lower systolic blood pressure levels. Replacement of SB or LPA with MVPA yielded lower BMIs.

CONCLUSION

Shorter sleep during the night is common among patients with early RA and is associated with adverse risk factors for CVD.

Subjective sleep disturbances at the time of diagnosis in patients with polymyalgia rheumatica and in patients with seronegative elderly-onset rheumatoid arthritis. A pilot study

Objectives

To investigate subjective sleep disturbances in patients with recent-onset polymyalgia rheumatica (PMR) and in patients with recent-onset seronegative elderly-onset rheumatoid arthritis (SEORA).

Material and methods

The study involved patients consecutively referred to two outpatient clinics from January to June 2018, with a diagnosis of PMR according to 2012 European League Against Rheumatism and American College of Rheumatology provisional criteria, and patients with a diagnosis of SEORA according to 1987 American Rheumatism Association criteria + age + absence of rheumatoid factor and anti-citrullinated peptide antibodies. All patients were naive to glucocorticoid (GC) therapy. After informed consent, we asked the patients to fill out a questionnaire including the Medical Outcomes Study – Sleep Scale (MOS-SS), pain Visual Analogic Scale (VAS), Cumulative Illness Rating Scale (CIRS), Neuropsychiatric Inventory (NPI), and how many minutes their morning stiffness (MS) lasted, at baseline and after 1 (T1) and 12 (T2) months. Differences between groups were calculated with the t-test; all p-values were two-sided and p < 0.05 was used to determine statistical significance. The study was approved by the local ethics committee and carried out in accordance with the Helsinki Declaration.

Results

The MOS-SS scores and MS duration were the only variables to show at T0 a significant difference between the two groups. In particular, MOS-SS scores were 47.6 ±8.4 (PMR) and 28.26 ±12.4 (SEORA), with p-values = 0.000. The MS duration was 90 ±9.9 minutes and 45 ±5.5 minutes, with p-value = 0.000. At T1 and T2, MOS-SS scores and MS duration decreased in the two groups, and no significant differences were found.

Conclusions

The study suggests that the assessment of subjective sleep disturbances can be useful in the differential diagnosis between recent-onset PMR and SEORA.

Fibromyalgia interferes with disease activity and biological therapy response in inflammatory rheumatic diseases

Fibromyalgia is one of the numerous comorbidities that may accompany inflammatory rheumatic diseases. Concomitant fibromyalgia in inflammatory rheumatic conditions can interfere with symptomatology, disease activity and overall management plan. The aim of the present narrative review article was to discuss the current evidence on (i) the prevalence/frequency of comorbid fibromyalgia in inflammatory rheumatic conditions, (ii) the role of fibromyalgia on disease activity, (iii) the impact of concomitant fibromyalgia on biological disease-modifying antirheumatic treatment outcomes and (iv) potential effectiveness of biological disease-modifying antirheumatic drugs on fibromyalgia-related symptoms among patients with inflammatory rheumatic diseases. A literature search was conducted through PubMed/MEDLINE Cochrane and Web of Science databases by using relevant keywords and their combinations. Studies representing different geographical areas of the world revealed that frequency rates of fibromyalgia are higher in inflammatory rheumatic diseases than those in the general population. Comorbid fibromyalgia interferes not only with the disease activity scores but also with the treatment outcomes and management plan. Further evidence is warranted in order to determine the potential benefits of biological disease-modifying antirheumatic drugs on fibromyalgia-related symptoms in patients with inflammatory rheumatic diseases.

Multimorbidity in COPD, does sleep matter?

A good night's sleep is a prerequisite for sustainable mental and physical health. Sleep disorders, including sleep disordered breathing, insomnia and sleep related motor dysfunction (e.g., restless legs syndrome), are common in patients with chronic obstructive pulmonary disease (COPD), especially in more severe disease. COPD is commonly associated with multimorbidity, and sleep disorders as a component of this multimorbidity spectrum have a further negative impact on COPD-related comorbidities. Indeed, concomitant diseases in COPD and in obstructive sleep apnea (OSA) are similar, suggesting that the combination of COPD and OSA, the so called OSA-COPD overlap syndrome (OVS), affects patient outcomes. Potential clinically important interactions of OVS exist in cardiovascular and metabolic disease, arthritis, anxiety, depression, neurocognitive disorder and the fatigue syndrome. Correct diagnosis for recognition and treatment of sleep-related disorders in COPD is recommended. However, surprisingly limited information is available and further research and improved diagnostic tools are needed. In the absence of clear evidence, we agree with the recommendation of the Global Initiative on Chronic Obstructive Lung Disease that sleep disorders should be actively searched for and treated in patients with COPD. We believe that both aspects are important components of the holistic approach required in patients with chronic multimorbid conditions.

Total knee arthroplasty for treatment of rheumatoid arthritis: A protocol for a systematic review of randomized controlled trial

BACKGROUND

Rheumatoid arthritis (RA) is a very tricky orthopedic condition. If it can not be treated fairly well, it may greatly affect quality of life in patients with RA, and even can cause disability. Total knee arthroplasty (TKA) has reported to treat patients with RA effectively. However, no study has systematically explored its efficacy and complications for patients with RA.

METHODS

Seven databases will be searched from their inceptions to the present without any language restrictions: MEDICINE, EMBASE, Cochrane Library, Web of Science, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure. Two authors will carry out all study selection, data extraction, and risk of bias assessment independently.

RESULTS

The primary outcome of joint pain will be measured by any pain scales, such as visual analogue scale. The secondary outcomes will include joint function, quality of life, and postoperative adverse events. The joint function will be measured by The Western Ontario and McMaster Universities Arthritis Index, Knee Injury and Osteoarthritis Outcome Score, or other relevant scales. The quality of life will be assessed by the 36-Item Short Form Health Survey or any related tools. In addition, postoperative adverse events will also be analyzed.

CONCLUSIONS

The findings of this study will summarize the latest existing evidence on the efficacy and safety of TKA for patients with RA.

ETHICS AND DISSEMINATION

This study does not need ethical approval, because it will not analyze individual data. The results of this study are expected to be disseminated at peer-reviewed journals.
