The effect of physical exercise on rheumatoid arthritis: An overview of systematic reviews and meta-analysis

Exploring the causes of elevated kinesiophobia in post-coronary stenting patients: a qualitative analysis in a cardiac rehabilitation setting

OBJECTIVES

The primary aim of this study is to investigate the factors contributing to the development of kinesiophobia in patients following coronary artery stent implantation, integrating perspectives from both patients and healthcare professionals. The main hypothesis is that understanding and methods for effectively overcoming the fear of exercise and improving the effectiveness of cardiac rehabilitation require further exploration from both patient and professional viewpoints.

DESIGN

This qualitative study used a semi-structured interview approach to gather data from participants.

SETTING

The study was conducted at a hospital in Gansu province, China, focusing on the level of care provided to cardiac rehabilitation patients.

PARTICIPANTS

A total of 11 cardiac rehabilitation patients identified as having kinesiophobia (Tampa Scale for kinesiophobia Heart, TSK-SV Heart >37) through screening and nine healthcare professionals participated in the study. The selection criteria included patients undergoing cardiac rehabilitation and professionals involved in their care.

RESULTS

The study identified a core theme, 'Navigating Fear and Uncertainty', encompassing five themes that elucidate how various factors contribute to the prevalent phenomenon of kinesiophobia among patients. These were further delineated into 11 subthemes: (1) physiological factors (fatigue, negative illness experiences), (2) psychological factors (hypervigilance, psychogenic anxiety and depression), (3) capacity factors (reduced physical abilities, lack of rehabilitation knowledge and skills), (4) motivational factors (low exercise self-efficacy, rehabilitation cognitive errors) and (5) support systems (primary caregivers, healthcare professionals and medical support). The results provide a qualitative understanding rather than quantitative measures, hence no CIs or statistical significance levels are provided.

CONCLUSIONS

The kinesiophobia observed in patients following coronary artery stent implantation stems from the combined influence of multiple factors, warranting early assessment and intervention by healthcare professionals. The study suggests that healthcare institutions should address the practical concerns faced by cardiac rehabilitation patients and enhance familial, medical and societal support systems to increase patient engagement and compliance with exercise rehabilitation. Further research is needed to develop and validate interventions based on these findings.

Factors influencing self-reported perceived health among United States adults with arthritis: A cross-sectional study

Limited knowledge exists of how various characteristics contribute to perceived health among the millions of United States (U.S.) adults with arthritis. This study explored the relationship between various factors and the perceived health of U.S. adults with arthritis. U.S. adults (18 years or older) alive (throughout 2021) and self-reporting a diagnosis of arthritis in the 2021 Medical Expenditure Panel Survey (MEPS) data were included in this study. Multivariable logistic regression was applied to determine the associations between independent variables (age, sex, race, ethnicity, education, employment, marriage, income, insurance, pain, chronic conditions, functional limitations, physical activity, smoking, region) and good versus poor perceived health, accounting for the complex survey design and weighting to reflect the U.S. population. Statistical significance was set at P < .05. The study included 5108 eligible participants (74.4% good health, 25.6% poor health). Factors associated with good perceived health included age ≥ 70 years (odds ratio [OR] = 3.5, 95% confidence interval [CI] = 2.0-6.2) and age 60 to 69 years (OR = 2.0, 95% CI = 1.2-3.5) versus age 18 to 39, females versus males (OR = 1.2, 95% CI = 1.0-1.5), white versus multiple races (OR = 2.0, 95% CI = 1.2-3.3), employed versus unemployed (OR = 2.0, 95% CI = 1.5-2.7), high versus low income (OR = 1.3, 95% CI = 1.0-1.7), little/moderate versus quite a bit/extreme pain (OR = 3.7, 95% CI = 3.0-4.7), <2 versus ≥ 2 chronic conditions (OR = 1.4, 95% CI = 1.1-1.8), no functional limitations versus functional limitations (OR = 2.0, 95% CI = 1.6-2.5), and regular versus no regular physical activity (OR = 2.2, 95% CI = 1.7-2.9). This study identified several factors that could be targeted to better manage and prevent arthritis in U.S. adults and improve perceived health.

Effects of Blood Flow Restriction Training on Strength and Functionality in People With Knee Arthropathies: A Systematic Review and Dose-Response Meta-Analysis of Randomized Controlled Trials

Background: Previous meta-analyses show contrasting findings regarding the effects of blood flow restriction training (BFRT) in different knee conditions. Furthermore, no previous dose-response analysis has been conducted to determine the dose of BFRT required for maximal strength and functionality adaptations. Objective: To analyze the evidence on the effects of BFRT on strength and functionality in patients with knee osteoarthritis or rheumatoid arthritis through a systematic review with dose-response meta-analysis. Methods: Included studies met the following criteria: participants with knee osteoarthritis or rheumatoid arthritis; low-load resistance BFRT as intervention; control group with traditional moderate or high intensity resistance training (MIRT and HIRT); include muscle strength and functionality as primary and secondary outcome measures, respectively; and only randomized controlled trials. A random-effects and a dose-response model estimated strength and functionality using estimates of the total repetitions performed. Results: We included five studies with a sample of 205 participants. No statistically significant differences were found between BFRT and MIRT or HIRT for strength (SMD = -0.06; 95% CI = -0.78-0.67; and p > 0.05) and functionality (SMD = 0.07; 95% CI = -0.23-0.37; and p > 0.05). We found an inverted U-shaped association between the increase in total repetitions and strength gain and between the increase in total repetitions and functional improvement. Conclusions: People with knee osteoarthritis or rheumatoid arthritis can use low-load BFRT for strength and functionality as a similarly effective alternative to MIRT and HIRT. A total of 2000 repetitions per BFRT program are necessary to maximize strength gains in these patients, while functional improvement requires 1800 total repetitions.

A scoping review of literature: What has been studied about mental health problems among individuals with ankylosing spondylitis?

BACKGROUND

Research on mental health problems in individuals with ankylosing spondylitis (AS) has rapidly expanded since 2013. However, the evidence in this field can appear fragmented due to the limited number of existing reviews that synthesize research findings.

AIM

To map the evidence regarding the prevalence, correlated factors, and interventions for mental health problems in the AS population.

METHODS

This review followed Arksey and O'Malley's framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. Six electronic databases were searched for studies published in English since January 2013. Study quality was assessed using the Mixed Methods Appraisal Tool, and data were narratively summarized and reported.

RESULTS

Seventy articles were included in this review. The prevalence rates of depression, anxiety, and sleep disorders ranged from 3.1 % to 66.0 %, 2.7 % to 78.0 %, and 1.7 % to 71.7 %, respectively. Correlated factors included sociodemographic variables, disease-related aspects, physical symptoms and function, and psycho-behavioral factors. Interventions were categorized into physical exercise, therapeutic, and psychosocial approaches.

CONCLUSIONS

Mental health problems are prevalent among individuals with AS, and the correlated factors are multidimensional. Interventions aimed at physical function, disease activity, and cognitive functions have been identified as critical strategies for addressing mental health problems. Further research is needed to design and develop effective interventions targeting these correlated factors, particularly psycho-social interventions, to prevent future deterioration.

Contributions of Dietary Patterns and Factors to Regulation of Rheumatoid Disease

Rheumatoid arthritis (RA) is a systemic autoimmune disease that commonly causes pain in joints and the progressive destruction of cartilage and bone, which significantly reduces the quality of life and increases the social burden. However, there is still no cure for RA, so it is highly important to explore additional adjuvant treatment methods. Studies have indicated that malnutrition, changes in intestinal microbiota, and changes in immune status caused by dietary imbalance are directly related to the onset of RA, indicating that dietary intervention may offer a simple, economical, and practical avenue to relieve RA. Therefore, in this review, we discuss the pathogenesis of RA and summarize the influence of different dietary patterns on RA. In particular, we pointed out that high-fat, high-sugar, and high-salt diets contribute to RA progression, whereas the Mediterranean diet (MD) is beneficial for preventing RA. Furthermore, the ingredients of food, such as dietary fiber, probiotics, and vitamins, help reduce the level of inflammation and relieve joint pain, which may play critical roles in the treatment of RA. Therefore, dietary intervention provides a potential effective approach for adjuvant therapy of RA.

Effects of exercise in primary Sjögren's syndrome: a systematic review and meta-analysis of randomized clinical trials

PURPOSE

To systematically review the effects of exercise interventions on pain, fatigue, quality of life, disease activity, aerobic capacity, and dryness in primary Sjögren's syndrome (pSS), and to determine the most effective type of exercise.

MATERIALS AND METHODS

A literature search was conducted using Web of Science, PubMed/MEDLINE, ProQuest, SCOPUS, Cochrane Library, and PEDro databases. Randomized clinical trials (RCTs) examining the effects of exercise interventions in patients with pSS were included. Methodological quality was assessed using the Risk of Bias version-2 tool and PEDro scale.

RESULTS

Five RCTs, including 269 female patients with pSS were analyzed. High-quality studies indicated that exercise interventions significantly improved pain (p = 0.008), fatigue (p < 0.00001), quality of life (p = 0.0003), and aerobic capacity (p = 0.009) compared to controls. Sensitivity analysis indicated that resistance exercise was particularly effective, significantly improving pain (p < 0.00001), fatigue (p < 0.00001), quality of life (p < 0.00001), and disease activity (p = 0.02).

CONCLUSION

Exercise interventions may offer significant benefits in reducing pain and fatigue, as well as improving quality of life and aerobic capacity, in patients with pSS compared to no-treatment. Resistance exercise appears to be more effective than other exercise models.

Cost-utility analysis of longstanding exercise therapy versus usual care in people with rheumatoid arthritis and severe functional limitations

OBJECTIVE

To evaluate the cost-effectiveness of longstanding personalized exercise therapy compared with usual care in people with rheumatoid arthritis (RA) and severe functional disability.

METHOD

In this cost-utility analysis of a randomized controlled trial (n = 215), with 1 year follow-up, the study population comprised individuals with RA and reported severe difficulties in performing basic daily activities. Assessments were at baseline, 12, 26, and 52 weeks, with measurements of costs including medical and non-medical costs as recorded by patients and healthcare providers. Quality-adjusted life-years (QALYs) were estimated using the EuroQol 5 dimensions 5 levels (EQ-5D-5L) and EuroQol Visual Analogue Scale (EQ-VAS). Costs and QALY differences were analysed according to the intention-to-treat principle using cost-effectiveness acceptability curves.

RESULTS

The 1 year societal costs were non-significantly in favour of the usual care group, with a small difference of €180 [95% confidence interval (CI) €-4493 to €4852]. The QALYs were non-significantly in favour of the intervention group, by 0.02 according to the EQ-5D-5L (95% CI -0.05 to 0.09) and by 0.04 according to the EQ-VAS (95% CI 0.00 to 0.08). For a willingness-to-pay threshold of €50 000 per QALY, the intervention was the cost-effective strategy with 60% certainty.

CONCLUSION

This economic evaluation showed no clear economic preference for either group, as the intervention costs were higher in the intervention group, but partly compensated by other cost savings and improved QALYs. Despite severe RA, patients had better clinical outcomes compared with usual care, suggesting no economic reasons to refrain from exercise therapy.

Online physical activity resources for individuals with rheumatoid arthritis: an environmental scan and quality appraisal

OBJECTIVES

To review publicly available physical activity (PA) resources for individuals with rheumatoid arthritis (RA). Aims were to find online print and audiovisual resources, review their characteristics and critically examine their quality from medical, exercise and behavioural science perspectives.

DESIGN

An environmental scan was completed using the Google search engine, following a pragmatic approach to reviewing patient-facing self-care resources.

DATA SOURCES

We used combinations of common search terms for RA and PA. The first five pages of results were reviewed for patient-facing resources.

ELIGIBILITY CRITERIA

Resources were included if they were (1) included RA-specific content, (2) provided specific PA recommendations, (3) written in English and (4) freely available.

DATA EXTRACTION AND SYNTHESIS

Two independent experts completed a medical review of resources to ensure appropriateness for RA. Data were then extracted by two reviewers using a standardised template to record resource characteristics. Two research team members and two patient partners independently evaluated resources for readability, understandability and actionability. Finally, the quality of exercise recommendations and behaviour change technique use was evaluated by an expert reviewer.

RESULTS

The search yielded 23 RA-specific PA resources, 17 of which passed the medical review. All 10 print resources and 7 audiovisual resources were created in English-speaking countries. The mean reading grade was 9.0±1.5. Print resources had mean understandability of 80.0±9.8% and actionability of 60.0±27.7%. Audiovisual materials had mean understandability of 86.0±9.2% and actionability of 86.9±22.9%. The quality of exercise recommendations was low. Only one resource provided comprehensive cardiovascular exercise advice, and two resources provided comprehensive strength exercise advice. 3-14 behaviour change technique groups were featured in each resource. The most common groups were 'shaping knowledge' and 'natural consequences'.

CONCLUSIONS

The quality of RA-specific PA resources is variable. Some high-quality resources exist that provide actionable PA behaviour change advice. Healthcare teams may refer patients to these resources. However, more work is needed to improve the overall quality of resources. Codevelopment with patients, providers and exercise behaviour change experts is recommended, ensuring resources are actionable, contain clear exercise recommendations and promote behaviour change.

Is Physical Exercise Beneficial for People with Primary Sjögren’s Syndrome? Findings from a Systematic Review

Background: The aim of the study was to identify and critically evaluate the best available evidence on the impact of physical exercise on patients with primary Sjögren’s syndrome. Methods: Studies were searched in four electronic databases (PubMed, Web of Science, Scopus, and SportDiscus) from their inception up to September 2024. The methodological quality of the included studies was assessed using the 10-point Physiotherapy Evidence Database (PEDro) scale and the Methodological Index for Non-Randomized Studies (MINORS). Results: A total of four randomized controlled trials and one comparative study were analyzed. The training programs evaluated varied in duration, ranging from 12 to 28 weeks. Exercise was found to have a positive intra-group impact on fatigue, quality of life, and functional capacity. However, exercise does not demonstrate superior effects compared to standard treatment for improving quality of life and disease impact. Conclusions: It is essential to increase the number of studies involving individuals with primary Sjögren’s syndrome across various exercise conditions to more comprehensively evaluate the potential benefits.

A comparative cross-sectional study of psychological distress, fatigue, and physical activity in patients with rheumatoid arthritis, systemic lupus erythematosus, and Sjögren's disease

Introduction

Anxiety and depression are common in patients with rheumatic diseases, but their impact across conditions like rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and primary Sjögren's disease (SjD) is still not well understood. This study aims to compare depression, anxiety, and fatigue, and their effects on disease activity and physical activity in these conditions.

Methods

From January 2019 to March 2021, patients with RA, primary SjD and SLE were assessed consecutively in a monocentric cross-sectional study at the rheumatology outpatient clinic of the Hannover Medical School. Standardized questionnaires were used to assess depression, anxiety, fatigue, disease activity, functional impairment, and physical activity in these patients.

Results

Of 445 patients, 36.9% had RA, 32.8% SLE, and 30.3% SjD, with most being female (RA 76.2%, SLE 85.6%, SjD 87.4%). Depression (28.5%) and anxiety (31.2%) were common, particularly in SLE (28.8%) and SjD (36.3%) vs. RA (22%, p 0.002). Physical inactivity was higher in SLE (44.5%) and SjD (44.4%) than in RA (39.0%), especially in depressed patients (p 0.011). A significant proportion of patients retired early, especially in SLE (85%) and SjD (66%) vs. RA (49%, p 0.001). Disease activity correlated with psychological status (p < 0.05).

Conclusions

Depression and anxiety are highly prevalent in RA, SLE, and SjD, particularly in SLE and SjD. The study highlights the need for early psychological evaluation and integrated care involving rheumatologists and mental health professionals to address these issues and improve physical and mental well-being.

Neighborhood Characteristics and Walking Behavior Among Adults With Arthritis: A National Health Interview Survey Study

OBJECTIVE

This study investigated the association of perceived neighborhood qualities with likelihood of transit walking, leisure walking, neighborhood walking, and meeting physical activity (PA) recommendations among US adults with arthritis.

METHODS

This cross-sectional study used 2020 National Health Interview Survey data. Included participants were adults who reported with clinician-diagnosed arthritis and who reported the ability to walk. Exposures of interest were perceived neighborhood attributes. Outcomes were transit walking, leisure walking, neighborhood walking, and meeting PA recommendations. Standardized mean difference percentage (SMD%) was used to assess relationships between exposures and outcomes, with an SMD% >10% resulting in inclusion in final adjusted multivariate logistic regression models for odds of outcomes. All analyses were weighted to account for complex survey methodology.

RESULTS

The analytic sample included 7,322 adults with arthritis. Fully adjusted logistic regression models showed the presence of roads to walk on was associated with meeting PA recommendations (odds ratio [OR] 1.26, 95% confidence interval [CI] 1.07-1.49]). Three attributes were positively associated with transit walking, whereas safety from crime was negatively associated (OR 2.33, 95% CI 1.75-3.10; OR 1.49, 95% CI 1.17-1.91; OR 1.67, 95% CI 1.34-2.08; and OR 0.70, 95% CI 0.53-0.92, respectively). Roads to walk and places to walk and relax were associated with leisure and neighborhood walking (OR 1.46, 95% CI 1.21-1.76; OR 1.56, 95% CI 1.34-1.82; OR 1.58, 95% CI 1.29-1.93; and OR 1.63, 95% CI 1.40-1.90, respectively).

CONCLUSION

This study identified several neighborhood characteristics associated with higher a likelihood of walking behaviors among adults with arthritis. Factors associated with walking behavior varied by the type of walking. The shared correlates between leisure and neighborhood walking imply they occur in the same setting. Patients with arthritis may benefit from exercise recommendations that are informed by the presence or absence of facilitating infrastructure in their neighborhoods.

Health-related quality of life profiles in patients with rheumatoid arthritis: a latent profile analysis

BACKGROUND

Rheumatoid arthritis (RA) is a common rheumatic disease that most commonly affects joints and negatively impacts individuals' health-related quality of life (HRQoL). Although some studies have explored HRQoL of RA patients, existing studies treated RA patients as a homogeneous group based on their overall HRQoL and ignore the heterogeneity of patients' HRQoL patterns. This study aimed to identify subgroups of RA patients based on their HRQoL and variables associated with group membership.

METHODS

This was a multi-center cross-sectional study conducted at 3 tertiary hospitals. All participants completed standardized questionnaires including demographic variables, HRQoL, physical function, disease activity and self-efficacy. Latent profile analysis was used to identify the optimal number of subgroups (profiles) and multinomial logistic regression analysis was used to explore variables associated with profile membership.

RESULTS

The analysis revealed 3 profiles of RA patients: poor HRQoL (N = 92, 60.9%), moderate HRQoL but poor role function (N = 45, 29.8%), good HRQoL (N = 14, 9.3%). Regression analysis revealed that patients with worse physical function were more likely to belong to "poor HRQoL" and "moderate HRQoL but poor role function" profile. Additionally, patients with junior high school or below educational level were less likely to belong to "moderate HRQoL but poor role function" profile.

CONCLUSION

This study identified 3 profiles of HRQoL within RA patients and found that physical function and educational level was associated with HRQoL profiles. The finding can provide the basis for developing tailored interventions to specific subgroups of RA patients.

Effect of traditional Chinese Yijinjing exercise on hand dysfunction in rheumatoid arthritis patients: a randomized controlled trial

Introduction

Rheumatoid arthritis (RA) patients often experience significant hand dysfunction. Yijinjing, a traditional Chinese exercise, has been recognized for its benefits to mind-body health. This study aimed to evaluate the efficacy and safety of Yijinjing in improving hand dysfunction among individuals with RA.

Methods

This research was conducted as a single-center, outcome-blinded, randomized controlled trial. A total of 66 eligible RA participants were randomly assigned in a 1:1 ratio to either the Yijinjing exercise group (YJJG) with sessions conducted three times per week over a 12-week period or the control group (CG), which maintained ordinary activities. Various outcomes were assessed, including the Michigan Hand Outcomes Questionnaire (MHQ), handgrip strength, active range of motion (AROM), RA disease activity, the Health Assessment Questionnaire Disability Index (HAQ-DI), levels of anxiety and depression, and wrist ultrasound, all of which were collected at baseline and the week 12.

Results

At the end of the 12 weeks, the YJJG demonstrated significant improvements in MHQ scores compared to the CG (p < 0.05), alongside enhancements in handgrip strength and AROM, specifically in wrist extension, radial deviation, and metacarpophalangeal flexion (p < 0.05). Wrist ultrasound scores did not exhibit a significant increase in the YJJG, meaning no inflammation aggravation (p > 0.05). Additionally, morning stiffness duration, Disease Activity Score 28-ESR (DAS28-ESR), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) levels showed significant improvement in the YJJG (p < 0.05). Both groups reported enhancements in quality of life, as well as reductions in anxiety and depression scores, with the YJJG displaying greater improvements overall (p < 0.05). Importantly, no adverse events or significant abnormalities in vital signs were observed in either group.

Conclusion

Yijinjing exercise may effectively enhance hand function, handgrip strength, and flexibility in RA patients with low disease activity. Furthermore, it appears to improve quality of life and reduce anxiety and depression without exacerbating joint inflammation.

Walking pace is a protective factor for rheumatoid arthritis: a mendelian randomization study

Walking pace is a simple and functional form of exercise and a strong predictor of health, but little is known about its causal association with rheumatoid arthritis. This study aimed to investigate the causal effect of WP on the developing RA using Mendelian randomization analysis. The genetic variation associated with WP was selected as an instrumental variable from the latest genome-wide association studies. Summary-level data for the outcomes were obtained from the corresponding GWAS. The inverse-variance weighted method was used as the primary MR analysis. The results were further tested using a multivariable MR approach based on Bayesian model averaging. Confounders (BMI, SMK, HBP, TD) with close associations with RA were included in the analysis. An observational study with individual data from UK Biobank was performed to reinforce our findings. The MR results indicated the significant inverse associations of WP with the risk of RA (odds ratio (OR), 0.31; 95% confidence interval (CI), 0.15, 0.62; p = 1.05 × 10 -3). After adjusting for the risk factors, the associations for WP and RA did not change substantially. Observational study results demonstrated the same effect of WP on reducing the risk of RA. The Mendelian randomization analysis and observational study provide evidence suggesting that walking pace is a protective factor for rheumatoid arthritis. Given its simple measurement, walking pace may be a pragmatic target for interventions.

Managing rheumatoid arthritis and cardiovascular disease: the role of physical medicine and rehabilitation

INTRODUCTION

Cardiovascular disease (CVD) presents a significant challenge in rheumatoid arthritis (RA), a systemic chronic ailment affecting the joints and causing systemic inflammation. Effective RA management, including pharmacological and non-pharmacological interventions, is crucial for mitigating cardiac risk. Pharmacotherapy, though effective, can have adverse effects, leading many patients to seek complementary therapies. This study investigates the impact of physical medicine and rehabilitation on RA management in patients with cardiovascular disease, analyzing clinical data to assess the efficacy of integrated therapeutic approaches.

METHODS

This retrospective monocentric study draws upon data from patient records at the Rheumatology Department of the Regional Clinical Hospital of Shymkent, Kazakhstan, spanning 2019 to 2022. Data collected included demographic information, diagnoses, comorbidities, medical anamneses, lab results, and treatment regimens, including physical medicine and rehabilitation interventions. Data were summarized in Microsoft Excel. Statistical analysis was performed using IBM SPSS Statistics (version 26.0).

RESULTS

An analysis of 350 patients with RA identified 143 cases of concomitant CVD, with arterial hypertension being the most common cardiovascular disease. The prevalence of CVD among patients with RA was 40%, with a mean age of 58 years, peaking between 50 and 65 years. The majority of patients were women. A strong association was found between increased RA activity and elevated cardiovascular risk. Despite the widespread use of glucocorticosteroid therapy, rehabilitation coverage remained limited. A significant proportion of patients had elevated cholesterol and C-reactive protein levels, while those who engaged in physical therapy and rehabilitation had lower cholesterol levels. Comparative analysis of yoga integration into rehabilitation programs for patients with RA, alongside other modalities (kinesiotherapy, balneotherapy, and pilates), showed that yoga participants exhibited lower pain levels, reduced morning stiffness duration, and lower mean DAS-28 scores compared to those using alternative rehabilitation methods.

CONCLUSION

Integrating physical medicine and rehabilitation, particularly yoga, with pharmacological treatments appears promising for improving patient outcomes. Yoga has demonstrated benefits in reducing pain, morning stiffness, and disease activity. Continued research is essential to refine these approaches and enhance RA and CVD management in patients.

Disease Activity, Inflammation Markers, and Quality of Life Are Associated with Muscle Strength in Croatian Rheumatoid Arthritis Patients-A National-Based Study

Background and Objectives: Rheumatoid arthritis (RA) patients experience sarcopenia and decreased muscle mass and handgrip strength, leading to decreased quality of life and disability. The prevalence of RA varies across regions. This study aimed to evaluate the factors associated with RA in Croatian regional centres and explore correlations between clinical parameters and muscle strength. Materials and Methods: Included in this study were 267 stable RA patients from four Croatian clinical centres. The patients' mean age was 60.4 ± 12.0 years, with 12.7% of them being male. For each study participant, information was gathered on their anthropometric characteristics, clinical and laboratory indicators, quality of life, disease activity, and sociodemographics. Results: The main results showed that in the female RA participants, the significant positive predictors are weight, height, exercise, VAS, and haemoglobin level. The negative predictors are the use of conventional synthetic disease-modifying anti-rheumatic drugs, the use of biological disease-modifying anti-rheumatic drugs, the number of tender joints, the number of swollen joints, the estimated sedimentation rate, the C-reactive protein, the disease activity score, the parameters of the EQ5D, and being prescribed with three or more medications. In the male RA participants, significant predictors of muscle strength are only weight, height, and anxiety/depression difficulties, according to the EQ5D. Conclusions: This study showed correlations between muscle strength and the parameters of disease activity, inflammation parameters, health-related quality of life, therapy, and exercise in the female RA participants in Croatia.

A clinical practice guideline for the management of the foot and ankle in rheumatoid arthritis

Rheumatoid arthritis causes progressive joint destruction in the long term, causing a deterioration of the foot and ankle. A clinical practice guideline has been created with the main objective of providing recommendations in the field of podiatry for the conservative management of rheumatoid arthritis. Thus, healthcare professionals involved in foot care of adults with rheumatoid arthritis will be able to follow practical recommendations. A clinical practice guideline was created including a group of experts (podiatrists, rheumatologists, nurses, an orthopaedic surgeon, a physiotherapist, an occupational therapist and patient with rheumatoid arthritis). Methodological experts using GRADE were tasked with systematically reviewing the available scientific evidence and developing the information which serves as a basis for the expert group to make recommendations. Key findings include the efficacy of chiropody in alleviating hyperkeratotic lesions and improving short-term pain and functionality. Notably, custom and standardized foot orthoses demonstrated significant benefits in reducing foot pain, enhancing physical function, and improving life quality. Therapeutic footwear was identified as crucial for pain reduction and mobility improvement, emphasizing the necessity for custom-made options tailored to individual patient needs. Surgical interventions were recommended for cases which were non-responsive to conservative treatments, aimed at preserving foot functionality and reducing pain. Moreover, self-care strategies and education were underscored as essential components for promoting patient independence and health maintenance. A series of recommendations have been created which will help professionals and patients to manage podiatric pathologies derived from rheumatoid arthritis.

Stapled hemorrhoidopexy for hemorrhoids: A overview of systematic reviews and meta-analysis

Stapled hemorrhoidopexy has been used for years to treat hemorrhoids. Despite numerous systematic reviews and meta-analyses on the topic, inconsistent conclusions have left people uncertain about its effectiveness and raised doubts about the quality of these reviews.In order to provide reliable evidence for clinical practice, it is crucial to conduct an overview to assess the quality of MAs/SRs regarding the efficacy and complications of SH.A comprehensive search was performed across seven databases to identify MAs/SRs on the efficacy and complications of SH from inception to October 2023. The selected MAs/SRs were then assessed using three well-established tools: AMSTAR-2, PRISMA 2020and GRADE. These assessments provide a robust evaluation of the quality and reliability of the included MAs/SRs.We removed overlapping randomized controlled trials (RCTs) and conducted a new meta-analysis of the outcomes. The overview included 23 meta-analyses.In AMSTAR-2, three reviews were deemed moderate quality, nine reviews were classified as low quality, and eleven reviews were evaluated as critically low quality.In PRISMA 2020,certain deficiencies were exhibited, such as abstracts (0/23:0 %),final retrieval date (0/23:0 %), sensitivity analysis (6/23:26.09 %),publication bias assessment (11/23:47.83 %), the quality of evidence (2/23:8.70 %) and so on.In GRADE,twenty-six items were rated as moderate quality (27.96 %),forty-one items were rated as low quality (44.09 %) and twenty-six items were rated as critically low quality (27.96 %).SH has been found to be an effective intervention for reducing postoperative pain, shortening procedure time, and promoting wound healing. The re-analysis indicated that SH can reduce postoperative pain in hemorrhoid patients (odds ratio = 0.28, 95 % confidence interval [0.15,0.55], p = 0.0002; I2 = 74 %, p < 0.00001). But SH is associated with a higher risk of postoperative bleeding and recurrence of prolapse.Given that the reviews included in this overview were rated as low quality, caution should be exercised when interpreting the findings.

How Do Exercise, Sleep and Depression Affect Disease Scores and Quality of Life in Primary Sjögren's Syndrome Patients?

Purpose

Primary Sjögren's syndrome (PSS) has many effects such as fatigue, pain, physical activity limitation and sleep disturbance, which limit patient's daily and social lives. The aim of our study was to assess fatigue, depression, physical activity status and quality of life in patients with PSS, and to determine the relationship between these data and disease-related parameters.

Patients and Methods

This study was conducted with 117 primary Sjögren's syndrome patients. Demographic and anthropometric characteristics, disease activity (ESSDAI), quality of life scale (SF36), depression (Beck Depression Scale), physical activity status (International Physical Activity Questionnaire Short Form (IPAQ) score) and sleep status (Pittsburgh Sleep Quality Scale) of PSS patients were evaluated and relationships have been examined.

Results

According to the results of our study, we found that sleep disorders are common in PSS patients (74.4%). Overweight patients, particularly higher lean mass sleep better (r:-0.201, p:0.043). Poor sleep causes fatigue (p=0.062) and depression (p=0.030). Sleep disturbance could not be explained by depressive state alone. However, after controlling for depression, the effect of sleep on fatigue seriously decreases (p=0.311). Exercise did not improve sleep quality (p=0.35) and the rate of poor sleep was higher among who exercised (p=0.192).

Conclusion

Based on the results of our study, we believe that, treating depression in PSS patients is crucial for reducing fatigue. Patients need education on performing the correct exercises and weight gain should done in a professional manner. Gaining a deeper understanding of the multisystem involvement of the disease and the impact of exercise on the disease, will have positive effects on patient care and treatment decisions.

Disability, Physical Activity, and Their Correlates in Patients With Inflammatory Bowel Disease: A Portuguese Cross-Sectional Survey

Knowledge about disability and physical activity is critical for enhancing self- and clinical management of inflammatory bowel disease, but the interplay between the two is unknown. This study aimed to explore the correlates of disability and physical activity in patients with inflammatory bowel disease. A cross-sectional online survey was conducted in 2019 in Portuguese patients (n = 108) capturing disability, clinical factors including disease status and comorbidities, physical activity habits, and barriers. The magnitude of disability was moderate (mean [95% confidence interval] = 41.85 [38.39, 45.31]). Disease activity and comorbidities were the most important predictors of disability (Model 2, F(102) = 20.285, p < .001, R2 = 0.499, R2adj = 0.443). About 62% of the participants engaged in moderate (31.5%) to vigorous (30.6%) physical activities. Perceived effort to engage in physical activities was the sole predictor of total weekly physical activity (R2 = 0.070, R2adj = 0.044, p = .006). The amount of disability and physical activity were poorly associated (ρ = -0.144, p = .068). Findings encourage gastroenterology nurses and other healthcare providers involved in the comprehensive care of patients with gastrointestinal disorders to recommend regular physical activity to these patients as part of an overall health enhancement strategy. Disability and back pain should be given further attention.

Association of serum uric acid with right cardiac chamber remodeling assessed by cardiovascular magnetic resonance feature tracking in patients with connective tissue disease

Background

Right cardiac chamber remodeling is widespread in patients with connective tissue disease (CTD). Serum uric acid (SUA) is considered a potential independent risk factor for cardiovascular disease, and elevated SUA levels are often observed in patients with CTD. The correlation between SUA levels and right cardiac chamber remodeling remains unclear. This study investigated the association of SUA with right cardiac chamber remodeling as assessed by cardiac magnetic resonance feature-tracking (CMR-FT) in CTD patients.

Methods and results

In this cross-sectional study, a total of 104 CTD patients and 52 age- and sex-matched controls were consecutively recruited. All individuals underwent CMR imaging, and their SUA levels were recorded. The patients were divided into three subgroups based on the tertiles of SUA level in the present study. CMR-FT was used to evaluate the right atrial (RA) longitudinal strain and strain rate parameters as well as right ventricular (RV) global systolic peak strain and strain rate in longitudinal and circumferential directions for each subject. Univariable and multivariable linear regression analyses were used to explore the association of SUA with RV and RA strain parameters. Compared with the controls, the CTD patients showed significantly higher SUA levels but a lower RV global circumferential strain (GCS) and RA phasic strain parameters (all p < 0.05), except the RA booster strain rate. RV GCS remained impaired even in CTD patients with preserved RV ejection fraction. Among subgroups, the patients in the third tertile had significantly impaired RV longitudinal strain (GLS), RV GCS, and RA reservoir and conduit strain compared with those in the first tertile (all p < 0.05). The SUA levels were negatively correlated with RV GLS and RV GCS as well as with RA reservoir and conduit strain and strain rates (the absolute values of β were 0.250 to 0.293, all P < 0.05). In the multivariable linear regression analysis, the SUA level was still an independent determinant of RA conduit strain (β = -0.212, P = 0.035) and RV GCS (β = 0.207, P = 0.019).

Conclusion

SUA may be a potential risk factor of right cardiac chamber remodeling and is independently associated with impaired RA conduit strain and RV GCS in CTD patients.

The effectiveness and safety of lifestyle medicine and integrative therapies in inflammatory arthritis: an umbrella review using a hierarchical evidence gathering approach

Objective

An umbrella review was conducted to provide a comprehensive evaluation of the evidence on lifestyle medicine and integrative therapies for inflammatory arthritis.

Methods

Five electronic databases were searched for umbrella reviews, meta-analyses, and systematic reviews of randomised controlled trials on acupuncture, diet, exercise, herbal medicine, nutrient supplements, and mind-body therapies for rheumatoid arthritis, spondyloarthritis, and gout published from January 2012 to December 2022. The primary outcomes were functional status and quality of life. Quality assessment was performed using the A MeaSurement Tool to Assess systematic Reviews (AMSTAR-2) tool, and the certainty of evidence for our primary outcomes was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach where possible.

Results

We included 52 reviews. Exercise was beneficial for functional status in both rheumatoid arthritis and spondyloarthritis, with moderate certainty of evidence. Chinese herbal medicine in combination with disease-modifying anti-rheumatic drugs may improve functional status in rheumatoid arthritis (very low certainty evidence). Acupuncture may improve functional status in rheumatoid arthritis and pain in both rheumatoid arthritis and gout; however, the evidence is of very low certainty. Evidence for other therapies was not clinically significant; however, it suggests possible benefits from quercetin and polyunsaturated fatty acids. Yoga may result in a moderate improvement in functional status when used as an adjunct to medication; however, the certainty of evidence is very low. Diet interventions offered inconsistent improvements to functional status in rheumatoid arthritis, spondyloarthritis, and gout with low to very low certainty.

Conclusion

Exercise should be prescribed for people with rheumatoid arthritis and spondyloarthritis. More research is needed to confirm or refute evidence for Chinese herbal medicine, acupuncture, yoga, and anti-inflammatory diets.

'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.

Physical activity guidance in the rheumatology clinic-what matters for patients with rheumatoid arthritis? A qualitative study

Higher proportions of patients with rheumatoid arthritis (RA) are physically inactive compared to the general population. A barrier to engaging in physical activity (PA) may be lack of consistent PA guidance from health professionals (HPRs). This qualitative study aimed to explore daily PA levels and the patients' perspectives on current and future PA guidance from HPRs. We recruited 20 participants from five rheumatology departments in Denmark. The participants differed in socio-demography and clinical characteristics based on results from an earlier cross-sectional study. The interviews were conducted by telephone, online platforms or face-to-face. Data analysis was based on reflexive thematic analysis. Thirteen participants were female and mean age was 55 years. We generated four themes; (1) Acceptance of the arthritis is a process, which attributed to acknowledging RA as part of life before fully engagement in PA and exercise. (2) Daily physical activity-motivation, barriers and benefits, reflecting the participants' preferred types of activities and motivations and barriers to PA. (3) Physical activity guidance-your own responsibility? This theme reflected how participants missed more comprehensive discussions with HPRs about PA. (4) It is essential how, when and where physical activity guidance is provided, referring to participants' preferences for future PA guidance in the rheumatology clinic. The study emphasizes that an integrated focus on PA should be part of the rheumatology clinic. However, HPRs may need adequate training in how to guide and motivate patients with RA towards increased PA.

Quality of reporting and nature of harms in clinical trials on supervised exercise in patients with rheumatoid arthritis or axial spondyloarthritis

To describe the quality of reporting and the nature of reported harms in clinical studies on the effectiveness of supervised exercises in patients with rheumatoid arthritis (RA) or axial spondyloarthritis (axSpA). We performed a systematic review, searching eight databases up to February 2023. Randomized controlled trials (RCTs) evaluating supervised exercises in adults with RA or axSpA were considered eligible. Data on harms were extracted according to the CONSORT Harms 2022 Checklist. Among others, it was recorded if harms were prespecified or non-prespecified. Moreover, the nature of reported harms was listed. Forty RCTs were included for RA and 25 for axSpA, of which 29 (73%) and 13 (52%) reported information on harms. In 13 (33%) RCTs in RA and four (16%) in axSpA, the collection of harms outcomes was described in the methods section. Prespecified outcomes were reported by eight (RA) and two (axSpA) RCTs. Non-specified harms outcomes were reported by six (RA) and four (axSpA) RCTs. Prespecified harms outcomes included measures of pain, disease activity, inflammation, and structural joint changes. The nature of non-prespecified harms outcomes varied largely, with pain being most common. A considerable proportion of trials on supervised exercise in RA or axSpA does not or inadequately report harms outcomes. Pain was the most commonly reported prespecified or non-specified harm. For a considerate interpretation of the balance between benefits and harms of supervised exercise in RA or axSpA, use of the CONSORT Harms 2022 Checklist for the design, conduct and reporting of trials is advocated.

The Role of Daily Steps in the Treatment of Major Depressive Disorder: Secondary Analysis of a Randomized Controlled Trial of a 6-Month Internet-Based, Mindfulness-Based Cognitive Behavioral Therapy Intervention for Youth

BACKGROUND

Current evidence supports physical activity (PA) as an adjunctive treatment for major depressive disorder (MDD). Few studies, however, have examined the relationship between objectively measured PA and MDD treatment outcomes using prospective data.

OBJECTIVE

This study is a secondary analysis of data from a 24-week internet-based, mindfulness-based cognitive behavioral therapy program for MDD. The purpose of this analysis was twofold: (1) to examine average daily step counts in relation to MDD symptom improvement, and whether pain moderated this relationship; and (2) to examine whether changes in step activity (ie, step trajectories) during treatment were associated with baseline symptoms and symptom improvement.

METHODS

Patients from the Centre for Addiction and Mental Health were part of a randomized controlled trial evaluating the effects of internet-based, mindfulness-based cognitive behavioral therapy for young adults (aged 18-30 years old) with MDD. Data from 20 participants who had completed the intervention were analyzed. PA, in the form of objectively measured steps, was measured using the Fitbit-HR Charge 2 (Fitbit Inc), and self-reported depression severity was measured with the Beck Depression Inventory-II (BDI-II). Linear regression analysis was used to test PA's relationship with depression improvement and the moderating effect of pain severity and pain interference. Growth curve and multivariable regression models were used to test longitudinal associations.

RESULTS

Participants walked an average of 8269 steps per day, and each additional +1000-step difference between participants was significantly associated with a 2.66-point greater improvement (reduction) in BDI-II, controlling for anxiety, pain interference, and adherence to Fitbit monitoring (P=.02). Pain severity appeared to moderate (reduce) the positive effect of average daily steps on BDI-II improvement (P=.03). Higher baseline depression and anxiety symptoms predicted less positive step trajectories throughout treatment (Ps≤.001), and more positive step trajectories early in the trial predicted greater MDD improvement at the end of the trial (Ps<.04). However, step trajectories across the full duration of the trial did not significantly predict MDD improvement (Ps=.40).

CONCLUSIONS

This study used objective measurements to demonstrate positive associations between PA and depression improvement in the context of cognitive behavioral treatment. Pain appeared to moderate this relationship, and baseline symptoms of anxiety and depression predicted PA trajectories. The findings inform future interventions for major depression. Future research with larger samples should consider additional moderators of PA-related treatment success and the extent to which outcomes are related to PA change in multimodal interventions.

YouTube® as a source of information for Spanish-speaking patients with rheumatoid arthritis

INTRODUCTION

Social media (SoMe) has reshaped access to health information, which may benefit patients with rheumatoid arthritis (RA), although an evaluation of the characteristics of contents for Spanish-speaking patients is lacking. We aimed to assess patient engagement, reliability, comprehensiveness, and quality of data uploaded to YouTube® for Spanish-speaking patients.

METHODS

We evaluated the videos uploaded to YouTube® in Spanish about RA. Information about video length, engagement (i.e., views, likes, popularity index), time online, and the source was retrieved; we appraised reliability (DISCERN), comprehensiveness (content score), and quality (Global Quality Score) using standardized scores.

RESULTS

We included 200 videos in the study and classified 67% of the videos as useful. These videos had a higher number of views (19,491 [10,132-61,162] vs. 11,208 [8183-20,538]), a longer time online (1156 [719-2254] vs. 832 [487-1708] days), and a shorter duration (6.3 [3.4-15.8] vs. 11.8 [7.4-20.3] min). Engagement parameters were similar between useful and misleading videos. Useful videos had higher reliability, comprehensiveness, and quality scores. Useful videos were mainly uploaded by independent users and government/news agencies; academic organizations offered only 15% of useful videos.

CONCLUSIONS

Most of the information in YouTube® for Spanish-speaking patients with RA is useful; however, patient engagement is similar between useful and misleading content. More substantial involvement of academia in developing high-quality educational multimedia is warranted.

Effects of a self-determination theory-based physical activity programme for postmenopausal women with rheumatoid arthritis: A randomized controlled trial

AIMS

The study aimed to develop and evaluate the effects of a self-determination theory-based, nurse-led, physical activity programme for postmenopausal women with rheumatoid arthritis.

METHODS

Between December 2019 and April 2020, this randomized controlled trial recruited 62 postmenopausal women with rheumatoid arthritis from a university-affiliated hospital in South Korea. The intervention group participated in a self-determination theory-based, nurse-led, physical activity programme that consisted of Tai Chi-based physical activity, a supportive psychosocial strategy, and interactive counselling for 16 weeks, and the control group continued to undergo their usual care.

RESULTS

There were statistically significant group-by-time interactions in physical activity and perceived sarcopenia, which favoured the intervention group. Additionally, the intervention group showed significant improvements in the perceived therapeutic efficacy of physical activity, grip strength, walking speed, disease activity score, and health-related quality of life.

CONCLUSIONS

The programme developed in this study can be an effective and feasible approach for postmenopausal women with rheumatoid arthritis in improving physical activity, selected osteosarcopenic outcomes, and health-related quality of life. Further research is required to investigate the long-term effects of this theory-based programme for postmenopausal women in diverse settings.

Adipokines in Rheumatoid Arthritis: Emerging Biomarkers and Therapeutic Targets

Rheumatoid arthritis (RA) is a chronic inflammatory disease manifested by joint involvement, extra-articular manifestations, and general symptoms. Adipose tissue, previously perceived as an inert energy storage organ, has been recognised as a significant contributor to RA pathophysiology. Adipokines modulate immune responses, inflammation, and metabolic pathways in RA. Although most adipokines have a pro-inflammatory and aggravating effect on RA, some could counteract this pathological process. The coexistence of RA and sarcopenic obesity (SO) has gained attention due to its impact on disease severity and outcomes. Sarcopenic obesity further contributes to the inflammatory milieu and metabolic disturbances. Recent research has highlighted the intricate crosstalk between adipose tissue and skeletal muscle, suggesting potential interactions between these tissues in RA. This review summarizes the roles of adipokines in RA, particularly in inflammation, immune modulation, and joint destruction. In addition, it explores the emerging role of adipomyokines, specifically irisin and myostatin, in the pathogenesis of RA and their potential as therapeutic targets. We discuss the therapeutic implications of targeting adipokines and adipomyokines in RA management and highlight the challenges and future directions for research in this field.

Sociocultural and Economic Disparities in Physical Therapy Utilization Among Insured Older Adults With Rheumatoid Arthritis

OBJECTIVE

To examine influences of sociocultural and economic determinants on physical therapy (PT) utilization for older adults with rheumatoid arthritis (RA).

METHODS

In these annual cross-sectional analyses between 2012 and 2016, we accessed Medicare enrollment data and fee-for-service claims. The cohort included Medicare beneficiaries with RA based on 3 diagnosis codes or 2 codes plus a disease-modifying antirheumatic drug medication claim. We defined race and ethnicity and dual Medicare/Medicaid coverage (proxy for income) using enrollment data. Adults with a Current Procedural Terminology code for PT evaluation were classified as utilizing PT services. Associations between race and ethnicity and dual coverage and PT utilization were estimated with logistic regression analyses. Potential interactions between race and ethnicity status and dual coverage were tested using interaction terms.

RESULTS

Of 106,470 adults with RA (75.1% female; aged 75.8 [SD 7.3] years; 83.9% identified as non-Hispanic White, 8.8% as non-Hispanic Black, 7.2% as Hispanic), 9.6-12.5% used PT in a given year. Non-Hispanic Black (adjusted odds ratio [aOR] 0.77, 95% CI 0.73-0.82) and Hispanic (aOR 0.92, 95% CI 0.87-0.98) individuals had lower odds of PT utilization than non-Hispanic White individuals. Adults with dual coverage (lower income) had lower odds of utilization than adults with Medicare only (aOR 0.44, 95% CI 0.43-0.46). There were no significant interactions between race and ethnicity status and dual coverage on utilization.

CONCLUSION

We found sociocultural and economic disparities in PT utilization in older adults with RA. We must identify and address the underlying factors that influence these disparities in order to mitigate them.

The Effect of Coaching Programs on Physical Activity and Pain in Patients with Rheumatoid Arthritis: A Systematic Review and Meta-analysis of Randomized Controlled Trials

OBJECTIVES

Coaching programs are used to achieve continuity in physical activity and reduce pain severity in patients with rheumatoid arthritis. Our aim was to examine the effects of coaching programs on physical activity and pain in patients with rheumatoid arthritis through randomized controlled trials.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Scopus, PubMed, Web of Science, Cochrane Library, Science Direct, EBSCOhost/CINAHL Complete, Springer Link, ProQuest, and Ovid databases were searched without year limitations in English until May 2023.

REVIEW/ANALYSIS METHODS

PRISMA guideline was employed. Comprehensive Meta-Analysis 3 software was used to analyze the meta-analysis data. Two researchers independently assessed the quality of the included studies using the Cochrane Collaboration tool.

RESULTS

This study included six randomized controlled trials with a total of 983 participants. It was determined that the coaching programs were effective in improving physical activity levels (95% CI = 0.14-0.39, Hedge's g = 0.27, p < .001) and reducing pain (95% CI = 0.07-0.39, Hedge's g = 0.23, p = .006) in the intervention groups compared with the control groups. It was determined that the application of coaching programs in the form of face-to-face sessions and phone calls at 7-10 sessions per year in patients diagnosed with rheumatoid arthritis was beneficial in pain management and improving physical activity levels.

CONCLUSIONS

Face-to-face sessions and telephone interviews are recommended as part of a coaching program for the maintenance of physical activity and pain management in patients with rheumatoid arthritis. Coaching programs can improve patients' functional status. There is a need to determine effective strategies by increasing awareness of the coaching programs implemented by nurses.

Chinese Herbal Medicine for the Treatment of Adult Viral Myocarditis: An Overview of Systematic Reviews and Meta-analyses of Randomized Controlled Trials

PURPOSE

Viral myocarditis (VMC) is a life-threatening disease that can affect all ages and genders, with middle-aged adults being particularly susceptible. Numerous systematic reviews have been conducted to investigate the efficacy and safety of Chinese herbal medicine (CHM) in treating adult viral myocarditis (AVM). The objective of this study was to conduct a comprehensive overview of systematic reviews and meta-analyses of randomized controlled trials (RCTs) regarding the efficacy and safety of CHM for AVM.

METHODS

A comprehensive systematic search was conducted across 8 electronic databases from their inception to June 23, 2022, augmented by manual searches of the gray literature. Systematic reviews were independently selected and data extracted in accordance with predetermined criteria by 2 reviewers. Included systematic reviews were assessed for methodologic and reporting quality using Assessing the Methodological Quality of Systematic Reviews 2 and Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The quality of evidence relating to outcome measures was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation tool. Recalculation of effect sizes and subsequent determination of 95% CIs were conducted with either a fixed-effects or random-effects model.

FINDINGS

The current overview of systematic reviews included a total of 6 systematic reviews, which reported on 67 RCTs with a participant pool of 5611 individuals. The findings of our study indicate that the combination of CHM and Western medications had positive effects on the effective rate, cure rate, ECG recovery, atrial premature contraction/premature ventricular contraction, left ventricular ejection fraction, myocardial enzymes, and improvement of clinical symptoms for AVM. The adverse drug reactions in the combination therapy group were generally less than or lighter than that in the Western medication group (relative risk = 0.79; 95% CI, 0.44-1.40; P > 0.05, I2 = 0).

IMPLICATIONS

Our research results provide evidence that combining CHM with Western medicine could offer potential benefits for patients with AVM. However, the number of studies included in our review is limited and the methodologic quality of these studies is modest. Therefore, there are potential uncertainties regarding the conclusion that CHM with Western medication may benefit patients with AVM. We call for more large-scale, high-quality studies with standardized designs to further verify and support our findings. This would promote a better understanding of the efficacy and safety profile of CHM and provide reliable reference evidence for clinical practice and policy making. Moreover, future research should explore optimal drug combinations, examine therapeutic doses and durations of CHM combination therapy, and evaluate its long-term efficacy and safety.

Physical Exercise and Occupational Therapy at Home to Improve the Quality of Life in Subjects Affected by Rheumatoid Arthritis: A Randomized Controlled Trial

BACKGROUND

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease that affects synovial membranes and typically causes joint pain and swelling. The resulting disability of RA is due to the erosion of cartilage and bone from the inflamed synovial tissue. Occupational therapy is a strategy and technique to minimize the joints' fatigue and effort. At the same time, physical exercise reduces the impact of systemic manifestations and improves symptoms in RA. This study investigates the role of a 30-day joint economy intervention (integration of physical exercise and occupational therapy) at home on the quality of life of subjects with RA.

METHODS

One hundred and sixty outpatients with RA were enrolled in a single-center trial with PROBE design and were divided into the intervention group (IG), which combined joint protection movements and physical exercise to maintain muscle tone at home, and the control group (CG). Both groups included 80 patients. In all patients, data from the disease activity score (DAS 28), health assessment questionnaire (HAQ), and short-form health survey (SF-12) "Italian version" were collected. In addition, to IG, a brochure was distributed, and the joint economy was explained, while to CG, the brochure only was distributed. The comparison between groups was made using Fisher's exact test for contingency tables and the z-test for the comparison of proportions. The non-parametric Mann-Whitney U test was used to compare quantitative variables between groups. The Wilcoxon signed-ranked test was used for post-intervention versus baseline comparisons.

RESULTS

Among the recruited patients, 54% were female. The mean age was 58.0 (42.4-74.7) for the CG and 54.0 (39.7-68.3) for the IG. Patients included in the IG had a higher cumulative illness rating scale for the evaluation of severity and comorbidity index (2.81 vs. 2.58; 2.91 vs. 2.59, respectively), as well as morning stiffness (33.8 vs. 25.0), even if not significant compared with CG patients. Our results indicate that, after 30 days of joint economy intervention at home, the DAS28 erythrocyte sedimentation rate (esr) and DAS28 C-reactive protein (crp), HAQ, and SF-12 mental component score were significantly improved (p = 0.005, p = 0.004, p = 0.009, and p = 0.010, respectively).

CONCLUSIONS

Our findings show that the combination of physical exercise and occupational therapy positively affects patients' quality of life with RA considering disease activity, global health status, and mental health.

Effects of Aquatic Exercises for Women with Rheumatoid Arthritis: A 12-Week Intervention in a Quasi-Experimental Study with Pain as a Mediator of Depression

BACKGROUND

Rheumatoid arthritis (RA) is characterized by low physical fitness, pain, and depression. The present study aimed to examine the effects of a supervised aquatic exercise program on physical fitness, depression, and pain in women with RA and determine whether decreases in pain mediate depression.

METHODS

Forty-three women with RA, divided into an experimental group (EG; n = 21) and a control group (CG; n = 23), participated in a 12-week exercise program. Treatment effects were calculated via standardized difference or effect size (ES) using ANCOVA adjusted for baseline values (ES, 95% confidence interval (CI)). A simple panel of mediation was executed to determine whether changes in pain mediated improvements in depression after controlling for confounding variables, such as age, physical activity, and body mass index (BMI).

RESULTS

The aquatic exercise program had trivial and small effects on physical fitness, large effects on pain, and moderate effects on depression. The mediation model confirmed the indirect effect of pain on the decrease of depression in the participants of the aquatic exercise program.

CONCLUSIONS

Participants with RA in the aquatic exercise program experienced improvements in physical fitness, depression, and joint pain. Moreover, the improvements in joint pain mediated improvements in depression.

Progression of pre-rheumatoid arthritis to clinical disease of joints: Potential role of mesenchymal stem cells

Rheumatoid arthritis (RA) related autoimmunity is developed at mucosal sites due to the interplay between genetic risk factors and environmental triggers. The pre-RA phase that leads to anti-citrullinated protein antibodies, rheumatoid factor, and other autoantibodies spread in the systemic circulation may not affect articular tissue for years until a mysterious second hit triggers the localization of RA-related autoimmunity in joints. Several players in the joint microenvironment mediate the synovial innate and adaptive immunological processes, eventually leading to clinical synovitis. There still exists a gap in the early phase of RA pathogenesis, i.e., the progression of diseases from the systemic circulation to joints. The lack of better understanding of these events results in the inability to answer questions about why only after a certain point of time the disease appears in joints and why in some cases, it simply remains latent and doesn't affect joints at all. In the current review, we focused on the immunomodulatory and regenerative role of mesenchymal stem cells and associated exosomes in RA pathology. We also highlighted the age-related dysregulations in activities of mesenchymal stem cells and how that might trigger homing of systemic autoimmunity to joints.

The effects of Tai Chi on physical function and safety in patients with rheumatoid arthritis: A systematic review and meta-analysis

Background: Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory autoimmune disease that results in the destruction of joints, connective tissues, muscle, tendons and fibrous tissue. Until now, there are no cure therapies. Objective: We aimed to assess the effectiveness of Tai Chi (TC) on RA patients by meta-analysis. Methods: The PubMed, Cochrane Library, EMBASE, web of science, China National Knowledge Infrastructure and Google Scholar were searched up to January 2023. We included randomized controlled trials (RCTs) or controlled clinical trials (CCTs) comparing TC to control conditions for RA patients. Review Manager (Version 5.3) software was used to analyze outcomes of time to walk 50 feet, joint tenderness, number of swollen joints or tender joints, handgrip strength, pain, the Health Assessment Questionnaire (HAQ) and withdraws overall. Results: A total of 351 patients with RA from six RCTs and three CCTs were included for meta-analysis. TC could also significantly decrease withdrawals overall in studies (OR = 0.28, 95% CI 0.12 to 0.67, p = 0.002). No significant treatment effects of physical function were identified of the other outcomes. Conclusion: Our findings indicated that TC was safe to RA patients, but it cannot improve physical function and pain. However, there is still lack of more evidence.

Implementation of physical activity interventions for people with inflammatory arthritis: an overview and future recommendations

Regular physical activity is important for both physical and mental health. This is particularly important for people with inflammatory arthritis, because of the benefits on both disease-specific and systemic outcomes and the increased risk of comorbidities such as cardiovascular disease. Despite a wealth of evidence supporting physical activity interventions, there remains a significant gap in implementation into routine care. This overview describes what implementation is, examines why it is important to consider implementation approaches to improve uptake of physical activity, highlights factors that influence successful implementation using exemplars from both osteoarthritis and inflammatory arthritis and recommends where future research is needed.

Research progress on rheumatoid arthritis-associated depression

Depression is an independent mood disorder and one of the most common comorbidities of rheumatoid arthritis (RA). Growing evidence suggests that there is two-way regulation between RA and depression, resulting in a vicious cycle of RA, depression, poor outcomes, and disease burden. The rising prevalence of RA-associated depression warrants a re-examination of the relationships between them. Here we provide an overview of the etiology and pathological mechanisms of RA-associated depression, and recent advances in treatment with biologics, which will facilitate the development of new and effective prevention and treatment strategies.

Clinical effect and biological mechanism of exercise for rheumatoid arthritis: A mini review

Rheumatoid arthritis (RA) is a common systematic, chronic inflammatory, autoimmune, and polyarticular disease, causing a range of clinical manifestations, including joint swelling, redness, pain, stiffness, fatigue, decreased quality of life, progressive disability, cardiovascular problems, and other comorbidities. Strong evidence has shown that exercise is effective for RA treatment in various clinical domains. Exercise training for relatively longer periods (e.g., ≥ 12 weeks) can decrease disease activity of RA. However, the mechanism underlying the effectiveness of exercise in reducing RA disease activity remains unclear. This review first summarizes and highlights the effectiveness of exercise in RA treatment. Then, we integrate current evidence and propose biological mechanisms responsible for the potential effects of exercise on immune cells and immunity, inflammatory response, matrix metalloproteinases, oxidative stress, and epigenetic regulation. However, a large body of evidence was obtained from the non-RA populations. Future studies are needed to further examine the proposed biological mechanisms responsible for the effectiveness of exercise in decreasing disease activity in RA populations. Such knowledge will contribute to the basic science and strengthen the scientific basis of the prescription of exercise therapy for RA in the clinical routine.

Effects of exercise interventions on cancer-related fatigue in breast cancer patients: an overview of systematic reviews

OBJECTIVE

This overview of systematic reviews aims to critically appraise and consolidate evidence from current systematic reviews (SRs)/meta-analyses on the effects of exercise interventions on cancer-related fatigue (CRF) in breast cancer patients.

METHODS

SRs/meta-analyses that explored the effects of exercise interventions on CRF in breast cancer patients compared with the routine methods of treatment and care were retrieved from nine databases. The methodological quality of the included SRs was appraised using A MeaSurement Tool to Assess systematic Reviews II (AMSTAR II). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to calculate the grading of outcomes in the included SRs. The exercise type, frequency, duration, and inclusion/absence of supervision were further evaluated with subgroup analyses. The Stata 16.0 software was utilized for data analysis.

RESULTS

Twenty-nine reviews were included. The overall methodological quality and level of evidence of the included reviews were unsatisfactory, with only three reviews rated as high methodological quality and no review identified as high-quality evidence. Moderate certainty evidence indicated that exercise could improve fatigue in breast cancer patients (SMD = - 0.40 [95%CI - 0.58, - 0.22]; P = 0.0001). Subgroup analysis based on the types of exercise showed that yoga (SMD = - 0.30 [95%CI - 0.56, - 0.05]; I2 = 28.7%) and aerobic exercise (SMD = - 0.29 [95%CI - 0.56, - 0.02]; I2 = 16%) had a significantly better effect on CRF in breast cancer patients; exercising for over 6 months (SMD = - 0.88 [95%CI - 1.59, - 0.17]; I2 = 42.7%; P = 0.0001), three times per week (SMD = - 0.77 [95%CI - 1.04, - 0.05]; I2 = 0%; P = 0.0001), and for 30 to 60 min per session (SMD = - 0.81 [95%CI - 1.15, - 0.47]; I2 = 42.3%; P = 0.0001) can contribute to a moderate improvement of CRF. Supervised exercise (SMD = - 0.48 [95%CI - 0.77, - 0.18]; I2 = 87%; P = 0.001) was shown to relieve CRF.

CONCLUSION

Exercise played a favorable role in alleviating CRF in breast cancer. Yoga was recommended as a promising exercise modality for CRF management in the majority of the included studies. Exercising for at least three times per week with 30 to 60 min per session could be recommended as a suitable dosage for achieving improvement in CRF. Supervised exercise was found to be more effective in alleviating CRF than unsupervised exercise. More rigorously designed clinical studies are needed to specify the exact exercise type, duration, frequency, and intensity to have an optimal effect on CRF in breast cancer patients.

Exercise-driven exacerbation of inflammation: contribution of animal models of rheumatoid arthritis and spondyloarthritis

PURPOSE

To describe the observations of studies that have explored the effects of exercise on inflammation and tissue remodeling in animal models of inflammatory arthropathies including Rheumatoid Arthritis and Spondyloarthritis.

METHODS

A search was performed at Pubmed, Scopus and Web of Science databases from 2010 to 2021. The selected articles were classified into those who reported positive and negative effects of exercise, and the characteristics of their experimental designs, including the animal model, the study groups, the exercise intervention and the evaluation techniques, were detailed.

RESULTS

Thirteen original articles that met the selection criteria were included. The effects of exercise on the joint biology of mice with inflammatory arthritis were controversial. Although exercise benefits have been observed in some experimental designs, the majority of them have shown that exercise leads to exacerbation of inflammation, tissue remodeling, and processes associated with arthritis such as oxidative stress and hypoxia.

CONCLUSION

Further research is necessary as the existing guidelines do not consider the negative effects of the exercise evidenced in animal models. The potential risks of exercise for patients should be considered.

Management of Sarcopenia in Patients with Rheumatoid Arthritis

This review summarizes the evidence for the management of sarcopenia in patients with rheumatoid arthritis (RA) in terms of drugs, exercise, and nutrition. Sarcopenia is a decrease in skeletal muscle mass and muscle strength or physical function. The prevalence of sarcopenia in patients with RA is higher than that in the general population. The treatment and management of sarcopenia in patients with RA are clinically important for long-term prognosis. One of the mechanisms of muscle metabolism is the pro-inflammatory cytokine pathway, which involves tumour necrosis factor α (TNF-α) and interleukin 6 (IL-6), and is a common pathway in the pathogenesis of RA. Thus, TNF-α and IL-6 inhibitors may play a potential role in controlling sarcopenia. In exercise therapy, a combination of moderate resistance and aerobic exercise may be effective in improving muscle strength, muscle mass, and physical function; however, intense exercise may exacerbate the inflammatory response in RA. Regarding nutrition, protein intake is generally considered beneficial, but other nutrients such as vitamin D and carotenoids have also been studied. Overall, there remains a lack of concrete evidence on sarcopenia treatment and management in patients with RA from any perspective; more longitudinal and intervention studies are needed in the future.

Acute effects of exercise on pain symptoms, clinical inflammatory markers and inflammatory cytokines in people with rheumatoid arthritis: a systematic literature review

Background

Exercise is advocated in the treatment of rheumatoid arthritis (RA). However, uncertainty around the acute effects of exercise on pain and inflammation may be stopping people with RA from exercising more regularly.

Objectives

To determine the acute effects of exercise on pain symptoms, clinical inflammatory markers, and inflammatory cytokines in RA.

Design

A systematic review of the literature.

Data sources and methods

Five databases were searched (PubMed, Cochrane Library, CINAHL, Scopus and SPORTDiscus); inclusion criteria were studies with acute exercise, a definite diagnosis of RA and disease characteristics assessed by clinical function (i.e., disease activity score, health assessment questionnaire and self-reported pain), clinical markers associated with inflammation (i.e., c-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)), and inflammatory cytokines (i.e., interleukin 6 (IL-6) and tumour necrosis factor alpha (TNF-α)).

Results

From a total of 1544 articles, initial screening and full text assessment left 11 studies meeting the inclusion criteria. A total of 274 people were included in the studies (RA = 186; control = 88). Acute bouts of aerobic, resistance, and combined aerobic and resistance exercise did not appear to exacerbate pain symptoms in people with RA.

Conclusion

Post-exercise responses for pain, clinical inflammatory markers and inflammatory cytokines were not different between people with or without RA. Exercise prescription was variable between studies, which limited between-study comparisons. Therefore, future investigations in people with RA are warranted, which combine different exercise modes and intensities to examine acute effects on pain symptoms and inflammatory markers.

Cost-effectiveness of motivational counselling and text reminders in patients with rheumatoid arthritis: results based on a randomised clinical trial

OBJECTIVE

The aim of this study was to evaluate the cost-effectiveness of an individually tailored intervention consisting of motivational counselling and text message reminders to reduce sedentary behaviour in comparison with usual lifestyle in patients with rheumatoid arthritis (RA).

METHODS

RA patients (n=150) were randomised to the intervention or control group. Costs of the intervention and healthcare utilisation during a 22-month follow-up period were reported. Outcomes were objectively measured as 24 hours/7 days sitting time and self-reported Health Assessment Questionnaire (HAQ) and EQ-5D scores at baseline, and 16 weeks, 10 and 22 months after baseline. Cost-effectiveness was reported as incremental cost-effectiveness ratios and statistical uncertainty presented as cost-effectiveness acceptability curves.

RESULTS

The intervention cost was estimated at €387 per participant. The mean incremental 22-month healthcare cost was €-1165 (95% bootstrap CI -5613 to 3283). An incremental 20%-point of the participants (CI 10.4% to 29.6%) reduced their daily sitting time more than 50 min and 36%-point reported better HAQ scores (change>0.22). The time-weighted health utilities (quality-adjusted life years (QALYs)) increased by 0.10 (CI 0.02 to 0.18) and 0.11 (CI 0.04 to 0.19) for EQ-5D index and EQ-VAS, respectively. The intervention dominated usual lifestyle by offering better outcomes and lower costs. With a threshold value of €30 000/QALY the intervention has a probability of 95% of being cost-effective.

CONCLUSION

This protocolised cost-effectiveness analysis showed that an individually tailored intervention aimed at reducing sedentary behaviour in patients with RA is improving participants' 22-month health status and reducing healthcare costs. These results suggest that the intervention should be implemented in routine rheumatology care.

Needle-Warming Moxibustion plus Multirehabilitation Training to Improve Quality of Life and Functional Mobility of Patients with Rheumatoid Arthritis after Medication

Objective

Patients treated with medication for rheumatoid arthritis (RA) often improve but continue to have active diseases. The study aims to investigate whether needle-warming moxibustion (NWM) plus multirehabilitation training can improve quality of life (QoL) and functional mobility of RA patients after medication.

Methods

Eighty-four RA patients were selected as study participants, including 42 patients receiving medication (medication group) and 42 patients receiving NWM plus multirehabilitation training (NWM + MRT group). The scores of disease symptoms, pain (visual analogue scale (VAS)), sleep quality (Pittsburgh Sleep Quality Index (PSQI)), functional mobility (Fugl-Meyer assessment scale (FMAS)), self-rating anxiety scale (SAS), self-rating depression scale (SDS), and QoL (SF-36) were compared before and after treatment. When patients were discharged from the hospital, they were given a questionnaire for treatment satisfaction.

Results

After treatment, decreases in the scores of the VAS, PSQI, SAS, and SDS were observed in both cohorts, especially in the NWM + MRT group (P < 0.05). The FMAS scores of upper limbs and lower limbs were increased after treatment, which were higher in the NWM + MRT group in comparison with the medication group (P < 0.05). Of note, patients in the NWM + MRT group scored higher in various dimensions of the SF-36 scale (P < 0.05), showing better QoL. The satisfaction survey showed that the NWM + MRT group had a higher proportion of patients being satisfied and a lower proportion of patients being dissatisfied (P < 0.05).

Conclusion

NWM plus multirehabilitation training could significantly attenuate disease symptoms, improve QoL, recover functional mobility, and reduce the risk of anxiety and depression in RA patients.

An Exercise and Educational and Self-management Program Delivered With a Smartphone App (CareHand) in Adults With Rheumatoid Arthritis of the Hands: Randomized Controlled Trial

BACKGROUND

Rheumatoid arthritis (RA) is a prevalent autoimmune disease that usually involves problems of the hand or wrist. Current evidence recommends a multimodal therapy including exercise, self-management, and educational strategies. To date, the efficacy of this approach, as delivered using a smartphone app, has been scarcely investigated.

OBJECTIVE

This study aims to assess the short- and medium-term efficacy of a digital app (CareHand) that includes a tailored home exercise program, together with educational and self-management recommendations, compared with usual care, for people with RA of the hands.

METHODS

A single-blinded randomized controlled trial was conducted between March 2020 and February 2021, including 36 participants with RA of the hands (women: 22/36, 61%) from 2 community health care centers. Participants were allocated to use the CareHand app, consisting of tailored exercise programs, and self-management and monitoring tools or to a control group that received a written home exercise routine and recommendations, as per the usual protocol provided at primary care settings. Both interventions lasted for 3 months (4 times a week). The primary outcome was hand function, assessed using the Michigan Hand Outcome Questionnaire (MHQ). Secondary measures included pain and stiffness intensity (visual analog scale), grip strength (dynamometer), pinch strength (pinch gauge), and upper limb function (shortened version of the Disabilities of the Arm, Shoulder, and Hand questionnaire). All measures were collected at baseline and at a 3-month follow-up. Furthermore, the MHQ and self-reported stiffness were assessed 6 months after baseline, whereas pain intensity and scores on the shortened version of the Disabilities of the Arm, Shoulder, and Hand questionnaire were collected at the 1-, 3-, and 6-month follow-ups.

RESULTS

In total, 30 individuals, corresponding to 58 hands (CareHand group: 26/58, 45%; control group: 32/58, 55%), were included in the analysis; 53% (19/36) of the participants received disease-modifying antirheumatic drug treatment. The ANOVA demonstrated a significant time×group effect for the total score of the MHQ (F_1.62,85.67=9.163; P<.001; η²=0.15) and for several of its subscales: overall hand function, work performance, pain, and satisfaction (all P<.05), with mean differences between groups for the total score of 16.86 points (95% CI 8.70-25.03) at 3 months and 17.21 points (95% CI 4.78-29.63) at 6 months. No time×group interaction was observed for the secondary measures (all P>.05).

CONCLUSIONS

Adults with RA of the hands who used the CareHand app reported better results in the short and medium term for overall hand function, work performance, pain, and satisfaction, compared with usual care. The findings of this study suggest that the CareHand app is a promising tool for delivering exercise therapy and self-management recommendations to this population. Results must be interpreted with caution because of the lack of efficacy of the secondary outcomes.

Effects of different physical training protocols on inflammatory markers in Zymosan-induced rheumatoid arthritis in Wistar rats

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by inflammation and involvement of the synovial membrane, causing joint damage and deformities. No effective drug treatment is available, and physical exercise has been utilized to alleviate the inflammatory processes. This study aimed to investigate the effects of different exercise training protocols on Zymosan-induced RA inflammatory markers in the right knee of Wistar rats. The rodents were subjected to aerobic, resisted, and combined physical training protocols with variations in the total training volume (50% or 100% of resistance and aerobic training volume) for 8 weeks. All physical training protocols reduced cachexia and systemic inflammatory processes. The histological results showed an increase in the inflammatory influx to the synovial tissue of the right knee in all physical training protocols. The rats that underwent combined physical training with reduced volume had a lower inflammatory influx compared to the other experimental groups. A reduction in the mRNA expression of inflammatory genes and an increase in anti-inflammatory gene expression were also observed. The physical training protocol associated with volume reduction attenuated systemic and synovial inflammation of the right knee, reducing the impact of Zymosan-induced RA in rats.

Effectiveness and safety of aerobic exercise for rheumatoid arthritis: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Rheumatoid arthritis (RA) can cause severe physical impairment and a reduced quality of life, and there is limited evidence for any effective intervention. Aerobic exercise may be beneficial for improving symptoms. Therefore, the purpose of this meta-analysis was to evaluate the effectiveness and safety of aerobic exercise for rheumatoid arthritis patients.

METHODS

PubMed, The Cochrane Library, Web of Science, EMBASE, CNKI, WanFang Data and VIP databases were searched. Randomized controlled trials of the effectiveness and safety of aerobic exercise for rheumatoid arthritis were included. Risks of bias were assessed by two independent reviewers using the methods described in the RevMan 5.3, GRADEpro and the Cochrane Handbook. Meta-analyses were performed to investigate the effects of aerobic exercise on rheumatoid arthritis.

RESULTS

A total of 13 RCTs were included, including 967 rheumatoid arthritis patients. The Meta-analysis results showed that aerobic exercise can improve functional ability [MD = - 0.25, 95% CI (- 0.38, - 0.11), P = 0.0002], relieve pain [SMD = - 0.46, 95% CI (- 0.90, - 0.01), P = 0.04], increase aerobic capacity [MD = 2.41, 95% CI (1.36, 3.45), P < 0.00001] and improve the Sit to Stand test score[MD = 1.60, 95% CI (0.07, 3.13), P = 0.04] with statistically significant differences.

CONCLUSION

Generally, aerobic exercise is beneficial and safe for RA patients and has a certain alleviating effect on the disease, such as functional ability improvement, pain relief and aerobic capacity increase. Limited by the quantity and quality of the included studies, future research with higher-quality studies needs to be conducted to verify the above conclusions.
