The effects of upper and lower limb exercise on the microvascular reactivity in limited cutaneous systemic sclerosis patients

Lifestyle interventions in the management of systemic sclerosis: a systematic review of the literature

Objectives

We aimed to investigate the efficacy of lifestyle interventions for the management of SSc.

Methods

We searched the MEDLINE, Embase, Web of Science and CINAHL databases in June 2021. We included studies conducted on five or more patients with SSc published between 1 January 2000 and the search date evaluating lifestyle interventions, excluding systematic reviews without meta-analyses. Critical appraisal was conducted using critical appraisal tools from the Joanna Briggs Institute. Thirty-six studies were included for full-text evaluation.

Results

A total of 17 studies evaluated the effect of physical exercise alone, whereas 14 studies evaluated educational interventions for mental health management, often with physical exercise as a central component. At an aggregated level, these studies support patient education and physical exercise for the improvement of physical function, in particular hand and mouth function. Studies on diet and nutrition were few (n = 5) and pertained to gastrointestinal as well as anthropometric outcomes; these studies were insufficient to support any conclusions.

Conclusion

Physical exercise and patient education should be considered for improving physical function in patients with SSc. These interventions can be provided alongside pharmacotherapy, but there is no evidence supporting that they can be a substitute. Further research should aim at assessing the effects of reductions of harmful exposures, including tobacco smoking and alcohol, improving sleep and enhancing social relations, three hitherto underexplored facets of lifestyle in the context of SSc.

Impact of a resilience-building energy management intervention for people with systemic sclerosis: a mixed methods study

Objectives

People with SSc often experience fatigue, which significantly affects daily life functioning and quality of life. We aimed to explore participants' experiences of a peer health-coached resilience-building energy management to enhance well-being (RENEW) intervention on symptoms and well-being and to use mixed methods to compare how SSc duration influenced the experiences of participants who had clinically significant fatigue improvement vs those who did not.

Methods

Semi-structured interviews were conducted with 21 participants from the parent clinical trial randomized to the RENEW intervention. Data were analysed using the rigorous and accelerated data reduction technique combined with thematic content analysis. A mixed methods approach used a joint display to identify themes related to the impact of SSc duration on fatigue improvement status. Participants were categorized into short/improvement, short/limited improvement, long/improvement, and long/limited improvement.

Results

Our team generated four themes: participant and peer health-coach relationship, physical and psychological well-being improvement, need for a tailored approach and easy program access through technology. Mixed methods analysis revealed that, regardless of SSc duration, participants with improved fatigue reported increasing self-awareness of SSc-related symptoms and learning coping strategies to manage fatigue. Participants in the short/improvement group reported preferences for slower pacing of the program and pairing with a coach with similar symptom severity. Participants in the long/limited improvement group sought SSc-specific symptom management information.

Conclusion

Incorporating peer health coaches and technology is beneficial for self-management interventions for people with SSc. Future tailoring of RENEW based on SSc duration and symptom severity is needed.

Systematic literature review informing the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus and systemic sclerosis

Through this systematic literature review, we assembled evidence to inform the EULAR recommendations for the non-pharmacological management of systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). We screened articles published between January 2000 and June 2021. Studies selected for data extraction (118 for SLE and 92 for SSc) were thematically categorised by the character of their intervention. Of 208 articles included, 51 were classified as robust in critical appraisal. Physical activity was the most studied management strategy and was found to be efficacious in both diseases. Patient education and self-management also constituted widely studied topics. Many studies on SLE found psychological interventions to improve quality of life. Studies on SSc found phototherapy and laser treatment to improve cutaneous disease manifestations. In summary, non-pharmacological management of SLE and SSc encompasses a wide range of interventions, which can be combined and provided either with or without adjunct pharmacological treatment but should not aim to substitute the latter when this is deemed required. While some management strategies i.e., physical exercise and patient education, are already established in current clinical practice in several centres, others e.g., phototherapy and laser treatment, show both feasibility and efficacy, yet require testing in more rigorous trials than those hitherto conducted.

Right Ventricular Morphology and Function after Exercise Training in People with Systemic Sclerosis: A Randomized Controlled Pilot Study

BACKGROUND

Vascular dysfunction and its concomitant multi-organ involvement, including cardiac involvement, affects prognosis in systemic sclerosis (SSc) patients. Regular exercise has demonstrated to be able to improve vascular function in SSc. However, the effects of an exercise program on the heart and specifically in right ventricular (RV) morphology and function in SSc have yet to be explored. The study aimed to examine whether a 3-month combined exercise program can affect RV morphology and function in SSc patients.

METHODS

Twenty-eight SSc patients were randomly allocated to either the exercise training (ET) or the control (CON) group. Baseline and follow-up assessments consisted of a cardiopulmonary exercise test along with both a conventional and a two-dimensional speckle tracking echocardiography (2DSTE) focused on RV morphology and function. Following the baseline assessments, Group ET participated in a supervised combined exercise program for 12 weeks, while group CON received their usual care.

RESULTS

The ET group demonstrated increases in peak oxygen consumption by 25.1% (p < 0.001), global RV free wall longitudinal systolic strain by 6.69% (p < 0.03), RV free wall longitudinal systolic strain of the basal segment by 13.5% (p < 0.001), and global RV four-chamber longitudinal systolic strain by 6.76% (p < 0.03) following the exercise program. No differences were observed in group CON.

CONCLUSIONS

Combined exercise improved cardiorespiratory efficiency and indices of RV systolic function, as assessed by the 2DSTE, in SSc patients.

Exploring the effects of a combined exercise programme on pain and fatigue outcomes in people with systemic sclerosis: study protocol for a large European multi-centre randomised controlled trial

Background

Pain, related to Raynaud’s phenomenon or digital ulceration, has been identified as very prevalent and debilitating symptoms of systemic sclerosis (SSc), both significantly affecting patients’ quality of life (QoL). Pharmacological therapeutic strategies were found not to be sufficiently effective in the management of SSc-induced pain and fatigue, and evidence for exercise is scarce. As yet, the effects of a long-term, tailored exercise programme on pain and fatigue in patients with SSc have not been explored. In addition to pain and fatigue, this study aims to evaluate the effects of exercise on QoL, physical fitness, functional capacity, and vascular structure in people with SSc (PwSSc).

Methods

This will be a multicentre (n = 6) randomised controlled clinical trial to assess the effect of a previously established, supervised 12-week combined exercise programme on pain and fatigue as compared to no exercise in PwSSc. The study will recruit 180 patients with SSc that will be allocated randomly to two groups. Group A will perform the exercise programme parallel to standard usual care and group B will receive usual care alone. Patients in the exercise group will undertake two, 45-min sessions each week consisting of 30-min high-intensity interval training (HIIT) (30-s 100% peak power output/30-s passive recovery) on an arm crank ergometer and 15 min of upper body circuit resistance training. Patients will be assessed before as well as at 3 and 6 months following randomisation. Primary outcomes of the study will be pain and fatigue assessed via questionnaires. Secondary outcomes include quality of life, structure of digital microvasculature, body composition, physical fitness, and functional capacity.

Discussion

Data from this multi-centre research clinical trial will primarily be used to establish the effectiveness of a combined exercise protocol to improve pain and fatigue in SSc. In parallel, this study will be the first to explore the effects of long-term exercise on potential microvascular alterations assessed via NVC. Overall, this study will provide sufficient data to inform current clinical practice guidelines and may lead to an improvement of QoL for patients with SSc.

Home-based rehabilitation improves functional capacity and quality of life in women with systemic sclerosis: A preliminary study

BACKGROUND

Recent initiatives, such as earlier diagnosis and treatment, have enhanced the survival of patients with systemic sclerosis (SSc). Despite these initiatives, there is extreme variability in rehabilitation strategies for these patients. In 2006, the Glittre-ADL test (TGlittre) was developed to evaluate functional capacity using multiple tasks similar to the activities of daily living (ADLs).

OBJECTIVES

To evaluate the impact of therapist-oriented home rehabilitation (TOHR) on functional capacity using TGlittre and to examine the effects of TOHR on physical function, hand function, and quality of life (QoL) among women with SSc.

METHODS

This quasi-experimental and longitudinal study included 12 women with SSc who underwent TOHR 3 times per week for 12 weeks. Before and after TOHR, functional capacity was assessed using TGlittre, physical function was examined by the Health Assessment Questionnaire Disability Index (HAQ-DI), hand function was evaluated using the Cochin Hand Functional Scale (CHFS) and handgrip strength (HGS), and QoL was evaluated using the Short Form-36 Health Survey Questionnaire (SF-36).

RESULTS

When comparing the pre- and post-TOHR values of TGlittre, a significant reduction was found in total time (p= 0.002) and manual time (p= 0.010). There was a nonsignificant decrease in HAQ-DI scores between pre- and post-TOHR (p= 0.07). Regarding hand function, there was a significant reduction in the CHFS between pre- and post-TOHR (p= 0.036), although no significant difference was observed in HGS between pre- and post-TOHR (p= 0.08). Regarding QoL, there was an increase in all SF-36 categories, although physical function was the only category that was significantly increased (p= 0.008).

CONCLUSION

After TOHR, patients with SSc are able to more quickly perform TGlittre tasks when considering both total and manual times. TOHR also positively affects manual skills and QoL.

The application of artificial gravity in medicine and space

Gravity plays a crucial role in physiology. The lack of gravity, like in long duration spaceflight missions, cause pathologies in e.g., the musculoskeletal system, cardiovascular deconditioning, immune system deprivation or brain abnormalities, to just mention a few. The application of artificial gravity through short-arm human centrifugation (SAHC) has been studied as a possible countermeasure to treat spaceflight deconditioning. However, hypergravity protocols applied by using SAHC have also been used to treat different, ground-based pathologies. Such gravitational therapies have been applied in Uruguay for more than four decades now. The aim of this overview is to summarize the most important findings about the effects of gravitational therapy in different, mainly vascular based pathologies according to the experience in the Gravitational Therapy Center and to discuss the current research in the field of hypergravity applications in medicine but also as multisystem countermeasure for near weightlessness pathologies. New insight is needed on the use of hypergravity in medicine and space research and application.

The Preventive Role of Physical Activity in Systemic Sclerosis: A Cross-Sectional Study on the Correlation with Clinical Parameters and Disease Progression

Although exercise is associated with improved health in many medical conditions, little is known about the possible influences of physical activity (PA) habits pre- and post- a diagnosis of systemic sclerosis (SSc) on disease activity and progression. This cross-sectional study assessed, for the first time, self-reported pre- and post-diagnostic PA levels with the aim to verify if changes in these levels were correlated with demographic/anthropometric data (e.g., weight, height, gender, age, BMI), disease duration, diagnostic/clinical parameters (e.g., skin involvement, pulmonary hemodynamic/echocardiographic data, disease activity) related to disease activity and progression, and quality of life in a population-based sample of patients with SSc. Adult participants (n = 34, age 56.6 ± 13.3 years) with SSc (limited cutaneous SSc, lcSSc, n = 20; diffuse cutaneous SSc, dcSSc, n = 9; sine scleroderma SSc, n = 5) were enrolled at the Division of Rheumatology and Clinical Immunology of the Humanitas Research Hospital. All medical data were recorded during periodic clinical visits by a rheumatologist. Moreover, all subjects included in this study completed extensive questionnaires to evaluate their health-related quality of life (HRQOL), and others related to health-related physical activity performed before (PRE) and after (POST) the diagnosis of disease. The linear regression analysis has shown that either a high Sport_index or Leisure_index in the PRE-diagnostic period was correlated with lower disease duration in dcSSc patients. Physical load during sport activity and leisure time accounted for ~61.1% and ~52.6% of the individual variation in disease duration, respectively. In lcSSc patients, a high PRE value related to physical load during sporting activities was correlated with a low pulmonary artery systolic pressure (sPAP) and the POST value of the Work_index was positively correlated with the left ventricular ejection fraction (LVEF), and negatively with creatine kinase levels (CK). Interestingly, the univariate analysis showed that Work_index accounts for ~29.4% of the variance in LVEF. Our analysis clearly reinforces the concept that high levels of physical load may play a role in primary prevention-delaying the onset of the disease in those subjects with a family history of SSc-as well as in secondary prevention, improving SSc management through a positive impact on different clinical parameters of the disease. However, it remains a priority to identify a customized physical load in order to minimize the possible negative effects of PA.

Can high-intensity interval training improve mental health outcomes in the general population and those with physical illnesses? A systematic review and meta-analysis

OBJECTIVE

High-intensity interval training (HIIT) is a safe and feasible form of exercise. The aim of this meta-analysis was to investigate the mental health effects of HIIT, in healthy populations and those with physical illnesses, and to compare the mental health effects to non-active controls and other forms of exercise.

DESIGN

Random effects meta-analyses were undertaken for randomised controlled trials (RCTs) comparing HIIT with non-active and/or active (exercise) control conditions for the following coprimary outcomes: mental well-being, symptoms of depression, anxiety and psychological stress. Positive and negative affect, distress and sleep outcomes were summarised narratively.

DATA SOURCES

Medline, PsycINFO, Embase and CENTRAL databases were searched from inception to 7 July 2020.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

RCTs that investigated HIIT in healthy populations and/or those with physical illnesses and reported change in mental well-being, depression, anxiety, psychological stress, positive/negative affect, distress and/or sleep quality.

RESULTS

Fifty-eight RCTs were retrieved. HIIT led to moderate improvements in mental well-being (standardised mean difference (SMD): 0.418; 95% CI: 0.135 to 0.701; n=12 studies), depression severity (SMD: -0.496; 95% CI: -0.973 to -0.020; n=10) and perceived stress (SMD: -0.474; 95% CI: -0.796 to -0.152; n=4) compared with non-active controls, and small improvements in mental well-being compared with active controls (SMD:0.229; 95% CI: 0.054 to 0.403; n=12). There was a suggestion that HIIT may improve sleep and psychological distress compared with non-active controls: however, these findings were based on a small number of RCTs.

CONCLUSION

These findings support the use of HIIT for mental health in the general population.

Exercise as a multi-modal disease-modifying medicine in systemic sclerosis: An introduction by The Global Fellowship on Rehabilitation and Exercise in Systemic Sclerosis (G-FoRSS)

Systemic sclerosis (SSc) is a heterogeneous multisystem autoimmune disease whereby its main pathological drivers of disability and damage are vascular injury, inflammatory cell infiltration, and fibrosis. These mechanisms result in diffuse and diverse impairments arising from ischemic circulatory dysfunction leading to painful skin ulceration and calcinosis, neurovascular aberrations hindering gastrointestinal (GI) motility, progressive painful, incapacitating or immobilizing effects of inflammatory and fibrotic effects on the lungs, skin, articular and periarticular structures, and muscle. SSc-related impairments impede routine activities of daily living (ADLs) and disrupt three critical life areas: work, family, social/leisure, and also impact on psychological well-being. Physical activity and exercise are globally recommended; however, for connective tissue diseases, this guidance carries greater impact on inflammatory disease manifestations, recovery, and cardiovascular health. Exercise, through myogenic and vascular phenomena, naturally targets key pathogenic drivers by downregulating multiple inflammatory and fibrotic pathways in serum and tissue, while increasing circulation and vascular repair. G-FoRSS, The Global Fellowship on Rehabilitation and Exercise in Systemic Sclerosis recognizes the scientific basis of and advocates for education and research of exercise as a systemic and targeted SSc disease-modifying treatment. An overview of biophysiological mechanisms of physical activity and exercise are herein imparted for patients, clinicians, and researchers, and applied to SSc disease mechanisms, manifestations, and impairment. A preliminary guidance on exercise in SSc, a research agenda, and the current state of research and outcome measures are set forth.

Suitability for e-health of non-pharmacological interventions in connective tissue diseases: scoping review with a descriptive analysis

Objective

Non-pharmacological interventions support patients with connective tissue diseases to better cope with and self-manage their diseases. This study aimed to map existing evidence on non-pharmacological interventions in patients with systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and mixed connective tissue diseases regarding content, feasibility and potential suitability in an e-health setting.

Methods

A literature search was performed in eight different databases in July 2020. The intervention’s content was extracted using the ‘Better reporting of interventions: template for intervention description and replication (TIDieR) checklist and guide’. A Sankey diagram and descriptive statistics were used to analyse the data and illustrate the relationships between the interventions.

Results

Of 8198 identified records, 119 papers were eligible. One hundred and four of them (87.4%) were conducted between 2000 and 2020, mainly in the USA (SLE n=24 (21.2%), SSc n=16 (14.2%)), Brazil (SLE n=8 (7.1%), SSc n=5 (4.4%)) and Italy (SLE n=0 (0%), SSc n=12 (10.6%)). Fifty-two studies (SLE n=24 (21.2%), SSc n=28 (24.8%)) used multicomponent interventions. The single interventions were physical exercises (SLE n=16 (14.2%), SSc n=17 (15.0%)), coaching/counselling (SLE n=11 (18.0%), SSc n=0 (0%)) and education (SLE n=2 (1.8%), SSc n=3 (2.7%)). Primary outcomes focused on physical function (SLE n=1 (0.9%), SSc n=15 (13.3%)), mouth opening in SSc (n=4 (5.9%)) and physical capacity (SLE n=2 (1.8%), SSc n=1 (0.9%)). No interventions for mixed connective tissue disease were found.

Conclusion

There was a great variety in the intervention’s content due to differences in body structure, activity limitations and participation restrictions in SLE and SSc. These results highlight the need for personalised, multicomponent, non-pharmacological interventions, which could be delivered as e-health interventions.

High-Intensity Interval Training in Older Adults: a Scoping Review

High-intensity interval training (HIIT) is an increasingly popular form of aerobic exercise which includes bouts of high-intensity exercise interspersed with periods of rest. The health benefits, risks, and optimal design of HIIT are still unclear. Further, most research on HIIT has been done in young and middle-aged adults, and as such, the tolerability and effects in senior populations are less well-known. The purpose of this scoping review was to characterize HIIT research that has been done in older adults including protocols, feasibility, and safety and to identify gaps in the current knowledge. Five databases were searched with variations of the terms, "high-intensity interval training" and "older adults" for experimental or quasi-experimental studies published in or after 2009. Studies were included if they had a treatment group with a mean age of 65 years or older who did HIIT, exclusively. Of 4644 papers identified, 69 met the inclusion criteria. The average duration of training was 7.9 (7.0) weeks (mean [SD]) and protocols ranged widely. The average sample size was 47.0 (65.2) subjects (mean [SD]). Healthy populations were the most studied group (n = 30), followed by subjects with cardiovascular (n = 12) or cardiac disease (n = 9), metabolic dysfunction (n = 8), and others (n = 10). The most common primary outcomes included changes in cardiorespiratory fitness (such as VO2peak) as well as feasibility and safety of the protocols as measured by the number of participant dropouts, adverse events, and compliance rate. HIIT protocols were diverse but were generally well-tolerated and may confer many health advantages to older adults. Larger studies and more research in clinical populations most representative of older adults are needed to further evaluate the clinical effects of HIIT in these groups.

Evidence and consensus-based recommendations for non-pharmacological treatment of fatigue, hand function loss, Raynaud's phenomenon, and digital ulcers in patients with systemic sclerosis

OBJECTIVE

Systemic sclerosis is a complex connective tissue disease affecting mental and physical health. Fatigue, hand function loss, and Raynaud's phenomenon are the most prevalent disease-specific symptoms of systemic sclerosis. This study aimed to develop consensus and evidence-based recommendations for non-pharmacological treatment of these symptoms.

METHODS

A multidisciplinary task force was installed comprising 20 Dutch experts. After agreeing on the method for formulating the recommendations, clinically relevant questions about patient education and treatments were inventoried. During a face-to-face task force meeting, draft recommendations were generated through a systematically structured discussion, following the nominal group technique. To support the recommendations, an extensive literature search was conducted in MEDLINE and six other databases until September 2020, and 20 key systematic reviews, randomized controlled trials, and published recommendations were selected. Moreover, 13 Dutch medical specialists were consulted on non-pharmacological advice regarding Raynaud's phenomenon and digital ulcers. For each recommendation the level of evidence and the level of agreement was determined.

RESULTS

Forty-one evidence and consensus-based recommendations were developed, and 34, concerning treatments and patient education of fatigue (12), hand function loss (8), and Raynaud's phenomenon/digital ulcers-related problems (14), were approved by the task force.

CONCLUSIONS

These 34 recommendations provide guidance on non-pharmacological treatment of three of the most frequently described symptoms in patients with systemic sclerosis. The proposed recommendations can guide referrals to health professionals, inform the content of non-pharmacological interventions, and can be used in the development of national and international postgraduate educational offerings.

High-intensity interval training can improve hand grip strength, inspiratory muscle, and quality of life in systemic sclerosis subjects

Introduction

Systemic sclerosis/scleroderma (SSc) is a chronic autoimmune disease with connective tissue, multi-organ, and multisystem involvement. The disease has three main characteristics, namely vasculopathy, fibrosis, and autoimmunity. The effect of high-intensity interval training (HIIT) in aerobic exercise on other rheumatic diseases has been studied, for example in patients with rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA). The purpose of this work is to investigate the effectiveness of HIIT of aerobics exercise on improving the inspiratory muscle, quality of life and functional ability for systemic sclerosis subjects.

Material and methods

The study was conducted on patients with confirmed systemic sclerosis who met the inclusion criteria. The research was carried out for 12 months in the outpatient clinic and gait laboratory of the Department of Physical Medicine and Rehabilitation.

Results

After HIIT in aerobic exercise, we found significant changes in inspiratory muscle (SNIP values 45.67 [30.92] vs. 54.25 [22.71]), handgrip (13.14 [4.42] vs. 15.63 [4.08]), walking speed (184.70 [26.86] vs. 246.6 [12.30]), metabolic equivalent (3.53 [0.30] vs. 4.21 [1.25]) and Scleroderma-Specific Health Assessment Questionnaire Disability Index for all visual analog scale (VAS) domains except Disability Index. Exercise approaches are characterized by repeated cycles of exercise interrupted by rest. For a range of clinical conditions, HIIT in aerobic exercise is known to remedy blood vessel function.

Conclusions

Our results suggest that HIIT in aerobic exercise has improved functional ability, respiratory muscle strength, and quality of life in SSc subjects. Training twice a week in a 12-week HIIT program is considered to be safe for this population. We have to consider internal and external factors that influenced the result. A larger sample and further exploration of the feasibility of combined exercise in SSc patients should be the focus for future research.

Efficacy of home-based physical activity interventions in patients with autoimmune rheumatic diseases: A systematic review and meta-analysis

INTRODUCTION

Physical activity (PA) has been receiving increasing interest in recent years as an adjuvant therapy for autoimmune rheumatic disease (ARDs), but there is scarce information about the efficacy of home-based PA for patients with ARDs.

OBJECTIVE

To perform a systematic review and meta-analysis on the efficacy of home-based physical activity (PA) interventions in improving health-related quality of life, functional capacity, pain, and disease activity in patients with ARDs.

METHODS

Searches were performed in PubMed, Web of Science, Scopus, Cochrane, CINAHL database and Sport Discus. Trials were considered eligible if they included a home-based physical activity intervention. The population included adults with autoimmune rheumatic diseases (e.g., rheumatoid arthritis, systemic lupus erythematosus, idiopathic inflammatory myopathies, systemic sclerosis and ankylosing spondylitis), comparisons included non-physical activity control or centre-based interventions (i.e., interventions performed on a specialized exercise centre) and the outcomes were quality of life, pain, functional capacity, disease activity and inflammation.

RESULTS

Home-based physical activity improved quality of life (p<0.01; g = 0.69; IC95%, 0.61 to 1.07) and functional capacity (p = 0.04; g = - 0.51; IC95%, -0.86; -0.16), and reduced disease activity (p = 0.03; g = - 0.60; IC95%, -1.16; -0.04) and pain (p = 0.01; g = -1.62; IC95%, -2.94 to -0.31) compared to the non-physical activity control condition. Additionally, home-based physical activity interventions were as effective as centre-based interventions for all investigated outcomes.

CONCLUSION

Home-based PA is an efficacious strategy to improve disease control and aleviate symptoms in ARD.

Investigation of the effectiveness of Tai Chi exercise program in patients with scleroderma: A randomized controlled study

BACKGROUND

and Purpose: There were studies showing the positive effects of Tai Chi on sleep, fatigue, endurance, balance, anxiety and depression in rheumatologic diseases. The aim of this study was to investigate the effects of Tai Chi exercise program on trunk endurance, balance, sleep, fatigue, anxiety and depression in patients with systemic sclerosis (SSc).

MATERIALS AND METHODS

28 patients were randomly divided into two groups as Tai Chi (n:14, 53.35 ± 10.86 years) and home exercise group (n:14, 52.64 ± 9.45 years). Trunk Lateral Endurance Test, Berg Balance Scale, Pittsburg Sleep Quality Index, Fatigue Severity Scale and Fatigue Impact Scale, Hospital Anxiety and Depression Scale was used for assesment. All evaluations were performed at baseline and at the end of the 10th week.

RESULTS

After training, a statistically significant difference was observed in all parameters in Tai Chi group (p:0.00); there was a significant difference in trunk endurance and sleep quality in the home exercise group (p:0.00-0.03) compared to pre-training. When the delta values between groups were compared, Tai Chi group was superior to home exercise group in all parameters except trunk endurance (p:0.00-0.01). No side effects were observed during the exercises.

CONCLUSION

As a result of our study; Tai Chi has a possitive effect on endurance, balance, sleep quality, fatique, anxiety and depression in patients with SSc. Tai Chi should be included in rehabilitation programs as a safe alternative type of exercise to improve trunk endurance, balance, sleep quality and reduce fatigue, anxiety and depression in patients with SSc.

Experiences of physical activity and exercise in individuals with systemic sclerosis: A qualitative study

INTRODUCTION

Exercise is emerging as an important part of the treatment in systemic sclerosis-patients with no-mild lung involvement. However, it has not been studied how patients experience physical activity and exercises. We thus explored and described experiences of physical activity/exercises in systemic sclerosis-individuals.

METHOD

Sixteen systemic sclerosis-patients were purposefully recruited to represent variation in gender, age, and lung disease. Semi-structured individual interviews were performed, transcribed and analyzed with qualitative content analysis.

RESULTS

Three themes (categories) emerged: 1) Essential for life and health (An effective treatment, Reduces fear of deterioration, and Feeling healthy and satisfied with oneself); 2) Disease-related hinders and other barriers (Disease consequences, Risk of worsening, and Non-disease related barriers); and 3) Self-care and/or support (Self-confidence in physical activity/exercise, and, Education and support from healthcare and other).

CONCLUSIONS

Physical activity/exercises were experienced as essential for life and health and as an effective treatment. It reduced fear of deterioration and made the participants feel healthy and satisfied with oneself. However, participants also experienced disease-related barriers like shortness of breath and pain, and they expressed a risk of worsening. Participants felt confidence in their physical activity/exercises and expressed that education and support from healthcare could be facilitating. Our findings add new knowledge about how systemic sclerosis-patients perceive physical activity/exercise and can contribute to the development of patient education and PA/exercise programs.

Raynaud's phenomenon

Raynaud's phenomenon (RP) is common, affecting approximately 5% of the population, and is important to the rheumatologist because it is often the presenting symptom of connective tissue disease, especially of systemic sclerosis (SSc)-spectrum disorders. RP therefore provides a window of opportunity for early diagnosis. When RP is associated with SSc it is particularly challenging to treat. This review begins with a discussion of some of the recent advances in our understanding of the pathogenesis of RP: it is through increased understanding of the complex pathophysiology of RP that we are most likely to develop new therapies. The following questions are then addressed (with three clinical scenarios demonstrating key principles of assessment and management): 1. How can we predict underlying connective tissue disease in the patient presenting with Raynaud's? 2. How can we measure severity of Raynaud's? 3. What are the latest advances in treatment of connective tissue disease-related digital vasculopathy?

Exploring the feasibility of an exercise programme including aerobic and resistance training in people with limited cutaneous systemic sclerosis

Objectives

It is suggested that exercise can improve the vascular function and quality of life (QoL) in people with systemic sclerosis (SSc), potentially offering clinical benefits to this population. Yet the feasibility of such an intervention remains untested. Therefore, the purpose of this study is to examine the feasibility of a combined exercise protocol (aerobic and resistance training) in people with limited cutaneous SSc (lcSSc).

Methods

Thirty-two lcSSc patients (66.5 ± 12 years old) were randomly allocated in two groups (exercise and control group). The exercise group underwent a 12-week exercise programme, twice per week. All patients performed the baseline, three- and six-month follow-up measurements where functional ability, body composition and QoL were assessed. Participants’ experiences were explored through interviews.

Results

Compliance was 92.6% with no dropouts. The individuals’ confidence to participate in the study’s exercise protocol for twice per week was 95%. The average value for the physical activity enjoyment scale was 103 ± 10 out of 119 (highest score). The mean values for the intention to engage in exercise twice per week were 6.4 ± 1 (likely) out of 7 (very likely). QoL for the exercise group showed to have a better life satisfaction, less anxiety and Raynaud’s phenomenon-accompanied pain.

Conclusions

Our results suggest that a combined exercise protocol was feasible for people with lcSSc, with no adverse events, resulting in high adherence and low attrition rates, high enjoyment levels and intentions for future engagement to this exercise. Thus, the specific protocol is a safe adjunct therapy for people with lcSSc.

Trial registration:ClinicalTrials.gov (NCT number): NCT03058887, February 23, 2017, https://clinicaltrials.gov/ct2/show/NCT03058887?term=NCT03058887&rank=1

Key Points • High-intensity interval training in combination with resistance training constitutes a feasible exercise protocol for people with lcSSc. • Overall, the exercise programme demonstrated high adherence and enjoyment levels and low attrition rates. • The exercise protocol was proved to be safe with no adverse events for people with lcSSc.

The effect and safety of exercise therapy in patients with systemic sclerosis: a systematic review

Given the shortcomings of previous literature reviews evaluating the effect and safety of exercise therapy in SSc, we aimed to carry out a systematic review of the literature specifically on this topic. A structured search strategy was performed in Medline (via PubMed) and other electronic databases from 1990 to 3 September 2019. Randomized controlled trials, observational designs, conference abstracts and trial registrations were included if they concerned SSc patients ≥18 years of age, exercise therapy and reported outcomes related to physical functioning. Nine articles were included. Four randomized controlled trials compared (a) hand exercises, (b) orofacial exercises, (c) aerobic exercises or (d) aerobic exercises plus resistance training with no exercise, demonstrating effects on hand function (a), maximum mouth opening (b), peak oxygen uptake (c + d) and quality of life. All five observational studies concerning hand, orofacial, aerobic and/or strengthening exercises reported improvements of hand function, mouth opening, aerobic capacity and/or muscle strength. In conclusion, the evidence on the effect and safety of exercise therapy in SSc is scanty.

Effects of Long-Versus Short-Term Exposure to the Mediterranean Diet on Skin Microvascular Function and Quality of Life of Healthy Adults in Greece and the UK

The beneficial effects of the Mediterranean diet (MD) adherence in reducing cardiovascular disease (CVD) risk and improving CVD-related physiological indices have been well-documented. However, the exact MD adherence duration needed for these effects to occur is under-researched. The aim of the present, two-arm, two-site study clinical trial was to assess the effects of long- vs. short-term MD adherence on the skin microvascular circulation, and quality of life. Two groups were recruited, one being long-term MD adherers (>5 years; from Greece; control group), and one of the non-adherers (from the UK), with the latter participating in a four-week MD intervention (intervention group). Our main outcome was skin microvascular function assessed by cutaneous vascular conductance (CVC). Secondary outcomes included quality of life, dietary intake, blood pressure and lipidemic profile. At the end of the intervention, both groups had high MD adherence. For the intervention group, significantly improved post-intervention CVC values were noted concerning the initial peak phase (2.0 ± 0.6 vs. 2.8 ± 0.8; p < 0.05). CVC values of the control group, were however higher at the plateau phase in comparison to the intervention group (intervention end; 3.8 ± 0.8 vs. 3.1 ± 1.2; p < 0.05). As per QoL, the physical domain was improved post-intervention (13.7 ± 1.2 vs. 15.9 ± 1.2; p < 0.05). No differences were observed in the lipidemic profile between groups, or between the baseline and final intervention phases. The findings indicate that although short-term MD adherence is effective in improving certain microvascular physiological properties and QoL domains, there is room for additional improvement, observed in long-term adherers. Our findings are important in the design of future, MD-based, lifestyle interventions, with the advisable durations differing between target groups.

Contrasting Effects of Short-Term Mediterranean and Vegan Diets on Microvascular Function and Cholesterol in Younger Adults: A Comparative Pilot Study

The Mediterranean diet has been shown to improve cardiovascular health. Vegan diets have demonstrated similar benefits, albeit in fewer studies. In a comparative pilot study, we compared the effects of a short-term Mediterranean Diet (MD) and Vegan Diet (VD) on microvascular function and cholesterol levels in a healthy population. Twenty-four young (aged 18 to 35 years) healthy volunteers followed a four-week intervention (MD = 12; VD = 12) ad libitum. Pre and post-intervention anthropometrics, microvascular function (assessed via LDF and expressed as raw CVC and %CVC MAX), dietary-analysis data (Calories, Protein, Carbohydrates, Total Fat, Saturated Fat, Fibre), Mean Arterial Pressure (MAP), Blood Pressure, Total Cholesterol (TC), High Density Lipoprotein (HDL-C) and TC:HDL-C were compared. MD participants reduced Total Fat intake (p = 0.05). Saturated Fat decreased (MD: p = < 0.001; VD: p = 0.004) and Fibre increased (MD: p = 0.02; VD: p = < 0.001) in both groups. Dietary changes reflected improvements in plateau raw CVC in the MD group (p = 0.005), and a reduction in TC (p = 0.045) and weight loss (p = 0.047) in the VD group. The MD led to improvements in microvascular function; the VD led to reduced TC and weight loss. Although both diets might offer CVD risk-reduction benefits, evidence for the MD appeared to be stronger due to changes in vasodilatory ability and NO bioavailability.
