Balneotherapy (or spa therapy) for rheumatoid arthritis

Recent development of mitochondrial metabolism and dysfunction in osteoarthritis

Osteoarthritis is a degenerative joint disorder characterized by cartilage degradation, synovial inflammation, and altered subchondral bone structure. Recent insights have identified mitochondrial dysfunction as a pivotal factor in OA pathogenesis, contributing to chondrocyte apoptosis, oxidative stress, and extracellular matrix degradation. Disruptions in mitochondrial dynamics, including impaired biogenesis, mitophagy, and metabolic shifts from oxidative phosphorylation to glycolysis, exacerbate cartilage damage by promoting the production of reactive oxygen species and matrix-degrading enzymes such as ADAMTS and MMPs. This review explores the molecular mechanisms underlying mitochondrial dysfunction in OA, emphasizing its role in cartilage homeostasis and inflammation. Furthermore, it highlights emerging therapeutic strategies targeting mitochondrial pathways, including antioxidants, mitophagy enhancers, and metabolic modulators, as potential interventions to mitigate disease progression, which offer promising avenues for advancing personalized and disease-modifying treatments in OA.

The role and intervention of mitochondrial metabolism in osteoarthritis

Osteoarthritis (OA), a prevalent degenerative joint disease, affects a substantial global population. Despite the elusive etiology of OA, recent investigations have implicated mitochondrial dysfunction as a significant factor in disease pathogenesis. Mitochondria, pivotal cellular organelles accountable for energy production, exert essential roles in cellular metabolism. Hence, mitochondrial dysfunction can exert broad-ranging effects on various cellular processes implicated in OA development. This comprehensive review aims to provide an overview of the metabolic alterations occurring in OA and elucidate the diverse mechanisms through which mitochondrial dysfunction can contribute to OA pathogenesis. These mechanisms encompass heightened oxidative stress and inflammation, perturbed chondrocyte metabolism, and compromised autophagy. Furthermore, this review will explore potential interventions targeting mitochondrial metabolism as means to impede or decelerate the progression of OA. In summary, this review offers a comprehensive understanding of the involvement of mitochondrial metabolism in OA and underscores prospective intervention strategies.

Global research hotspots and trends in exercise interventions for rheumatoid arthritis over the past two decades: A bibliometric and visualization study

Rheumatoid arthritis (RA) is a prolonged multifactorial autoimmune disease of unknown etiology. With the global population aging, the incidence of RA is increasing, highlighting the need for more effective treatments. Exercise interventions have been recognized as safe and effective for managing pain, improving function, and reducing fatigue in RA patients. However, the existing literature in this field lacks a thorough, organized, and clear line of analysis. In this study, we conducted a comprehensive analysis of the 20-year literature on exercise interventions for RA, aiming to identify hotspots and cutting-edge trends. Our objective is to provide subsequent researchers with valuable ideas and references. Using Cite Space, VOS viewer, and R-bibliometrix software for visualization and analysis, we compiled the main dataset from the web of science database, consisting of 1790 articles on exercise interventions in RA published between 2000 and 2023. Among these articles, the United States contributed the highest number of papers (433), while Karolinska Institutet ranked first institutionally with 90 papers. The study focused on the keyword's quality of life, cardiovascular disease, aerobic exercise, social support, psychology, and multidisciplinary care. The research highlighted the importance of clinical efficacy studies that investigate different types of exercise modalities (cardiorespiratory aerobic, resistance, aquatic, and neurological) either alone or in combination, to improve pain and function and reduce cardiovascular disease risk in patients with RA. Additionally, sedentary behavior, fatigue, and multidisciplinary care were identified as potential areas for further research. Overall, this study provides a scientific perspective on exercise interventions for RA and offers valuable insights for academics, funding organizations, and policymakers.

Assessment of complementary and alternative medicine methods in the management of ankylosing spondylitis, rheumatoid arthritis, and fibromyalgia syndrome

A wide variety of musculoskeletal, arthritic, connective tissue, and vasculitic diseases fall under the umbrella of "rheumatic diseases". Ankylosing spondylitis, rheumatoid arthritis, and fibromyalgia syndrome are the three members of this disease group with relatively high prevalence. Pharmacological options are at the center of therapeutic algorithms in treating rheumatic diseases, particularly in reducing inflammation. Despite significant advances in pharmacological treatment in recent years, achieving complete treatment success in a group of patients is impossible. Therefore, patients with rheumatic diseases frequently utilize alternative treatment options, such as complementary and alternative medicine. Complementary and alternative medicine is a broad category of health practices not part of the leading health system. Patients with rheumatic diseases turn to complementary and alternative medicine for various reasons, including restricted access to some treatments due to high prices and rigorous regulations, worries about drug side effects, and symptoms that continue despite pharmacological treatment. In addition, because complementary and alternative medicine options are considered natural, they are frequently accepted as well tolerated and have few harmful effects. Ankylosing spondylitis, rheumatoid arthritis, and fibromyalgia syndrome are the primary foci of this comprehensive review. First, we attempted to summarize the non-traditional physical medicine and complementary and alternative medicine options that can be utilized to manage these diseases. Second, we addressed the link between exercise and inflammation in rheumatic diseases. We briefly discussed the possible benefits of exercise-based approaches. In addition, we highlighted the benefits of cooperation between rheumatology and physical medicine-rehabilitation clinics.

Balneotherapy for chronic venous insufficiency

BACKGROUND

Chronic venous insufficiency (CVI) is a progressive and common disease that affects the superficial and deep venous systems of the lower limbs. CVI is characterised by valvular incompetence, reflux, venous obstruction or a combination of these symptoms, with consequent distal venous hypertension. Clinical manifestations of CVI include oedema, pain, skin changes, ulcerations and dilated skin veins in the lower limbs. It places a large financial burden on health systems. There is a wide variety of treatment options for CVI, ranging from surgery and medication to compression and physiotherapy. Balneotherapy (treatments involving water) may be a relatively cheap and efficient way to deliver physiotherapy to people with CVI. This is an update of a review first published in 2019.

OBJECTIVES

To assess the effectiveness and safety of balneotherapy for the treatment of people with chronic venous insufficiency.

SEARCH METHODS

We used standard, extensive Cochrane search methods. The latest search date was 28 June 2022.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials comparing balneotherapy to no treatment or other types of treatment for CVI. We also included studies that used a combination of treatments.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were 1. disease severity, 2. health-related quality of life (HRQoL) and 3.

ADVERSE EFFECTS

Our secondary outcomes were 1. pain, 2. oedema, 3. leg ulcer incidence and 4. skin pigmentation changes. We used GRADE to assess the certainty of evidence for each outcome.

MAIN RESULTS

We included nine randomised controlled trials involving 1126 participants with CVI. Seven studies evaluated balneotherapy versus no treatment, one study evaluated balneotherapy versus a phlebotonic drug (melilotus officinalis), and one study evaluated balneotherapy versus dryland exercises. We downgraded our certainty in the evidence due to a lack of blinding of participants and investigators, participant-reported outcomes and imprecision. Balneotherapy versus no treatment Balneotherapy compared to no treatment probably results in slightly improved disease severity signs and symptoms scores as assessed by the Venous Clinical Severity Score (VCSS; mean difference (MD) -1.75, 95% confidence interval (CI) -3.02 to -0.49; 3 studies, 671 participants; moderate-certainty evidence). Balneotherapy compared to no treatment may improve HRQoL as assessed by the Chronic Venous Insufficiency Quality of Life Questionnaire 2 (CIVIQ2) at three months, but we are very uncertain about the results (MD -10.46, 95% CI -19.21 to -1.71; 2 studies, 153 participants; very low-certainty evidence). The intervention may improve HRQoL at 12 months (MD -4.48, 95% CI -8.61 to -0.36; 2 studies, 417 participants; low-certainty evidence). It is unclear if the intervention has an effect at six months (MD -2.99, 95% CI -6.53 to 0.56; 2 studies, 436 participants; low-certainty evidence) or nine months (MD -6.40, 95% CI -13.84 to 1.04; 1 study, 59 participants; very low-certainty evidence). Balneotherapy compared with no treatment may have little or no effect on the occurrence of adverse effects. The main adverse effects were thromboembolic events (odds radio (OR) 0.35, 95% CI 0.09 to 1.42; 3 studies, 584 participants; low-certainty evidence), erysipelas (OR 2.58, 95% CI 0.65 to 10.22; 2 studies, 519 participants; low-certainty evidence) and palpitations (OR 0.33, 95% CI 0.01 to 8.52; 1 study, 59 participants; low-certainty evidence). No studies reported any serious adverse effects. Balneotherapy compared with no treatment may improve pain scores slightly at three months (MD -1.12, 95% CI -1.35 to -0.88; 2 studies, 354 participants; low-certainty evidence); and six months (MD -1.02, 95% CI -1.25 to -0.78; 2 studies, 352 participants; low-certainty evidence). Balneotherapy compared with no treatment may have little or no effect on oedema (measured by leg circumference) at 24 days to three months, but we are very uncertain about the results (standardised mean difference (SMD) 0.32 cm, 95% CI -0.70 to 1.34; 3 studies, 369 participants; very low-certainty evidence). Balneotherapy compared with no treatment may have little or no effect on the incidence of leg ulcers at 12 months, but we are very uncertain about the results (OR 1.06, 95% CI 0.27 to 4.14; 2 studies, 449 participants; very low-certainty evidence). Balneotherapy compared with no treatment may slightly reduce skin pigmentation changes as measured by the pigmentation index at 12 months (MD -3.60, 95% CI -5.95 to -1.25; 1 study, 59 participants; low-certainty evidence). Balneotherapy versus melilotus officinalis For the comparison balneotherapy versus a phlebotonic drug (melilotus officinalis), there was little or no difference in pain symptoms (OR 0.29, 95% CI 0.03 to 2.87; 1 study, 35 participants; very low-certainty evidence) or oedema (OR 0.21, 95% CI 0.02 to 2.27; 1 study, 35 participants; very low-certainty evidence), but we are very uncertain about the results. The study reported no other outcomes of interest. Balneotherapy versus dryland exercise For the comparison balneotherapy versus dryland exercise, evidence from one study showed that balneotherapy may improve HRQoL as assessed by the Varicose Vein Symptom Questionnaire (VVSymQ), but we are very uncertain about the results (MD -3.00, 95% CI -3.80 to -2.20; 34 participants, very low-certainty evidence). Balneotherapy compared with dryland exercises may reduce oedema (leg volume) after five sessions of treatment (right leg: MD -840.70, 95% CI -1053.26 to -628.14; left leg: MD -767.50, 95% CI -910.07 to -624.93; 1 study, 34 participants, low-certainty evidence). The study reported no other outcomes of interest.

AUTHORS' CONCLUSIONS

For the comparison balneotherapy versus no treatment, we identified moderate-certainty evidence that the intervention improves disease severity signs and symptoms scores slightly, low-certainty evidence that it improves pain and skin pigmentation changes, and very low-certainty evidence that it improves HRQoL. Balneotherapy compared with no treatment made little or no difference to adverse effects, oedema or incidence of leg ulcers. Evidence comparing balneotherapy with other interventions was very limited. To ensure adequate comparison between trials, future trials should standardise measurements of outcomes (e.g. disease severity signs and symptoms score, HRQoL, pain and oedema) and follow-up time points.

Balneotherapy and health-related quality of life in individuals with Rheumatoid arthritis: An observational study under real clinical practice conditions

Abstract: Introduction: To analyze the influence of balneotherapy applied under real clini-cal practice conditions on the quality of life and functionality of patients diagnosed with rheumatoid arthritis. Methods: Prospective, observational study conducted with a group of patients under real clinical practice conditions, with a 6-month follow-up. The partici-pants were beneficiaries of the social thermalism programme of the Spanish Ministry of Health, Consumption and Social Well-being, aged 60-80 years and diagnosed with rheu-matoid arthritis, who were treated at Fitero’s Spa (Spain). The study excluded those indi-viduals who had undergone another balneotherapeutic treatment in the previous 6 months, and those who had scheduled one in the following 6 months. Ten treatment ses-sions were applied. Each session included a bath and one or two additional techniques, which varied in each case, depending on the characteristics and preferences of the patient. The variables were gathered before initiating the treatment, and at 1, 3 and 6-months post-treatment. Results: The study included 49 individuals with an average age of 71.0 (SD 4.79) years. The variable “current health state” of EuroQol 5D-5L increased by 6.73 [-13.44 to -2.53] points and 6.26 [-12.07 to -0.46] in the first and third month, respectively. Pain was the dimension in which the largest number of participants reduced the level of their response in all the follow-up periods. Functionality showed an improvement of 0.196 [0.060 to 0.332] in the third month. Conclusions: The beneficial effects of balneotherapy on the health-related quality of life and functionality in individuals with rheumatoid arthritis can be positive.. Keywords: Balneotherapy, rheumatoid arthritis, quality of life, functionality.

Comparative efficacy and acceptability of non-pharmacological interventions in fibromyalgia: Protocol for a network meta-analysis

INTRODUCTION

Although several non-pharmacological interventions have been tested in the management of Fibromyalgia (FM), there is little consensus regarding the best options for the treatment of this health condition. The purpose of this network meta-analysis (NMA) is to investigate the comparative efficacy and acceptability of non-pharmacological interventions for FM, in order to assist clinical decision making through a ranking of interventions in relation to the most important clinical outcomes in these patients.

METHODS AND ANALYSIS

We will perform a systematic search to identify randomised controlled trials of non-pharmacological interventions endorsed in guidelines and systematic reviews. Information sources searched will include major bibliographic databases without language or date restrictions (MEDLINE, Cochrane Library, EMBASE, AMED, PsycINFO and PEDro). Our primary outcomes will be pain intensity, patient-reported quality of life (QoL), and acceptability of treatment will be our secondary outcome. Risk of bias of the included trials will be assessed using the Cochrane risk of bias tool (RoB2). For each pairwise comparison between the different interventions, we will present mean differences (MDs) for pain intensity and QoL outcomes and Relative Risks (RRs) for acceptability, both with respective 95% confidence intervals (CIs). Initially, standard pairwise meta-analyses will be performed using a DerSimonian-Laird random effects model for all comparisons with at least two trials and then we will perform a frequentist NMA using the methodology of multivariate meta-analysis assuming a common heterogeneity parameter, using the mvmeta command and network suite in STATA. In the NMA, two different types of control group, such as placebo/sham and no intervention/waiting list will be combined as one node called "Control". The competing interventions will be ranked using the P-score, which is the frequentist analogue of surface under the cumulative ranking curve (SUCRA) for the outcomes of interest at immediate- (intervention duration of up to 2 weeks), short- (over 2 weeks up to 12 weeks) and long-terms (over 12 weeks). The confidence in the results from NMA will be assessed using the Confidence in Network Meta-analysis (CINeMA) framework.

ETHICS AND DISSEMINATION

This work synthesises evidence from previously published studies and does not require ethics review or approval. A manuscript describing the findings will be submitted for publication in a peer-reviewed scientific journal.

Publication activity in water treatments: Web of Science-based bibliometric analysis of the last two decades

We evaluated the quantity and quality of scientific publications linked with water treatments using the Web of Science (WoS) database. The WoS was searching by using the following terms "hydrotherapy," "balneotherapy," "spa therapy," "spa treatment," "creno-balneotherapy," "water treatments," and "aqua therapy," on February 10th, 2022. The recorded data were the total number of articles, year of articles, country of articles, journal, document type, index data, and citation data. Also, the studies performed with natural source mineral water were marked to make a further subgroup analysis through quality and quantity. We obtained 816 articles; 667 (81.74%) were original research articles, and 149 (18.26%) were review articles. A statistically significant and increasing trend was shown in the publication about water treatments (p < 0.01). About three-quarters of the trials were sourced from high-income countries. Italy (n = 98; 12.01%); Turkey (n = 75; 9.19%); Australia (n = 65; 7.97%); Brazil (n = 46; 5.64%); and France (n = 38; 4.66%) were the most productive countries. Calculating the number of articles per million population, Hungary (3.38), Australia (2.53), and Italy (1.64) ranked in the top three. According to 100 billion dollars GDP, the top three countries were Brazil (24.41), Hungary (21.15), and Turkey (10.41). In the average citation calculation, the Netherlands (60.84), Israel (29.86), and Australia (29.06) were in the top three. The International Journal of Biometeorology was the leading journal for publication trials about water treatments. In the subgroup analysis, we found the total number of studies performed with natural source mineral water and non-specified source water trials as 430 and 386, respectively. We also presented that the natural source and non-specified water trials had a statistically significant and increasing trend between 2000 and 2021 (p < 0.01 and p < 0.01, respectively). The trials performed with natural source water mainly were sourced from Italy (n = 79; 18.37%), Turkey (n = 61; 14.19%), France (n = 38; 8.84%), Poland (n = 30; 6.98%), and Hungary (n = 29; 6.74%), the trials performed with non-specified water were sourced from Australia (n = 61; 15.80%), Brazil (n = 46; 11.92%), USA (n = 27; 6.99%), Italy (n = 19; 4.92%), and England (n = 18; 4.66%). The top journal of the natural source water trials was the International Journal of Biometeorology (n = 65; 15.12%), and for the non-specified water trials, it was the International Journal of Sports Physiology (n = 12; 3.11%).Our study presented an increasing trend in trial publications regarding water treatments between 2000 and 2021. Most of the trials were from high and upper-middle-income countries. We suggest that by demonstrating global productivity worldwide, our results can create more scientific attention on this topic and may promote the quantity and quality of the trials.

[The effect of natural mineral bicarbonate sodium-calcium water «Tib-1» on the antioxidant status of rats with adjuvant rheumatoid arthritis]

The combination of traditional basic pharmacotherapy for rheumatoid arthritis (RA) and physiotherapeutic methods can reduce the activity of the disease and accelerate the onset of remission, and therefore the development of new non-drug methods for the treatment of RA is relevant.

PURPOSE OF THE STUDY

Study of the effect of natural mineral water « Tib-1» on the lipid peroxidation system in an experiment with a model adjuvant-induced RA in rats.

MATERIAL AND METHODS

The object of the study were Wistar rats, divided into three groups: negative control (solvents), positive control (model of adjuvant-induced RA by subcutaneous injection of complete Freund's adjuvant) and experimental (correction of RA with mineral water « Tib-1», diluted in a ratio of 1:3 during the first 2 weeks from the moment the model was formed in the ad libitum mode). On the 3rd and 7th weeks in the blood of the animals were determined: the total number of leukocytes, the content of hydroperoxides according to Gavrilov, the level of malondialdehyde (MDA), catalase activity. Pathological changes in the hip and knee joints were recorded using radiography.

RESULTS

The inflammatory process in the positive control group by the 3rd week was characterized by an increase in the number of leukocytes by 66% (p<0.01) and was accompanied by an increase in MDA by 60% (p<0.001). By the 7th week, despite a relative increase in catalase activity (16%), the MDA level continued to be elevated compared to the negative control by 67% (p<0.001). Against the background of exposure to mineral water, inflammation decreased (the number of leukocytes in the "model/experiment" groups turned out to be reduced by 41%; p<0.01) and an increase in compensatory-adaptive reactions in the form of catalase activation was noted (by 8%; p<0.01), which was accompanied by a persistent (weeks 3 and 7) decrease in MDA output (by 20%; p<0.01). Using the method of radiation diagnostics, positive changes in the articular apparatus of experimental animals were revealed, consisting in the relief of signs of subchondral sclerosis of the bone heads, which were noted for animals of the model group.

CONCLUSION

The use of natural mineral water «Tib-1» helps to reduce the acute inflammatory response during the formation of adjuvant-induced RA in Wistar rats, initiates the normalization of the balance of pro- and antioxidant processes in the body, and minimizes the intensity of degenerative-inflammatory joint lesions.

Therapeutic Benefits of Balneotherapy on Quality of Life of Patients with Rheumatoid Arthritis: A Systematic Review

BACKGROUND

Rheumatoid arthritis (RA) is the most common inflammatory rheumatic disease. RA symptoms make the disease disabling and strongly impact the quality of life of patients. Among the available forms of treatment, balneotherapy seems to be one of the most common forms of nonpharmacological treatment for rheumatic disease. The aim was to explore the effectiveness of balneotherapy for improving the quality of life of patients with RA.

METHODS

Pubmed, Scopus, Web of Science and The Cochrane library were searched for randomized or clinical controlled trials published in English or Spanish until May 2021. Risk of bias of included articles were assessed using the Cochrane tool. A total 535 records were retrieved, and seven met the inclusion criteria. All the included studies showed statistically significant improvements in the quality of life of patients who received balneotherapy treatment despite differences in treatment administration. Sessions should be approximately 20 min long and use natural mineral waters enriched with elements, or mud, at a water temperature between 35-38 °C.

CONCLUSIONS

Balneotherapy benefits the quality of life of people with RA. The obtained results show positive effects for both mineral bathing and immersion in sand or mud on the quality of life of people who suffer from RA.

Peloidotherapy in rheumatoid arthritis: a pilot randomized clinical trial

To evaluate the additional effect and safety of peloidotherapy to usual care at short- and middle-term in patients with rheumatoid arthritis (RA). RA patients were recruited in the medical ecology and hydroclimatology department of Istanbul Medical Faculty and were randomized into two parallel groups. Peloidotherapy group was treated with heated mudpack (41-42 °C) on painful and active joints (5 days/week, during 2 weeks) + usual care. Control group received usual care alone. Randomization was performed by using a computer-generated table of random numbers and was blinded. The sequence was concealed until interventions were assigned. The investigator was blinded. The assessments were done before and after the intervention, 1 month and 3 months after the completion of treatment. The main criterion was the number of patients with low disease activity (DAS 28 ≤ 3.2) at the end of follow-up. Other judgment criteria were pain (VAS), patient's global assessment (VAS), physician's global assessment (VAS), Health Assessment Questionnaire (HAQ), Disease Activity Score (DAS 28), CRP, and ESR. Fifty-six patients were recruited and analyzed: 29 in peloidotherapy group and 27 in the control group between 11/2011 and 02/2012. At the third month, 9/29 patients were with low disease activity in peloidotherapy group and 4/27 in the control group (p = 0.15). There was a statistically significant improvement in favor of peloidotherapy group for HAQ during all follow-up period (0.25 vs 0.63, p = 0.007 at the end of the treatment, 0.29 vs 0.68 p = 0.007 at the 1st month and 0.30 vs 0.59, p = 0.040 at the 3^rd month). Pain (35vs50, p = 0.028), patient's global assessment (37vs53, p = 0.028), physician's global assessment (33vs48, p = 0.030), and DAS28 (3.76vs4.58, p = 0.049) improved significantly more in peloidotherapy group at the 3^rd month. There were no between group differences for ESR and CRP. There were no important adverse events. There is no significant improvement for the main criteria so we can't conclude that peloidotherapy has additional effect over usual care. But most of the other judgment criteria improved more in the peloidotherapy group than in the control group and peloidotherapy was well tolerated. A trial with higher statistical power is necessary to if we want to reveal the effects on disease activity and confirm the short and middle term efficiency of this treatment modality on pain and quality of life.

[Dental care in health resort institutions]

Over the past decades, a small yet convincing evidence base has accumulated that demonstrates the effectiveness of dental care for patients in health-resort (HR) settings. In addition to a positive local effect, complex HR care increases nonspecific resistance and promotes desensitization.

OBJECTIVE OF THE REVIEW

Addressing the HR rehabilitation in patients with various maxillofacial diseases for further consideration of the possibility of the increased use of HR care in dental practice.

MATERIAL AND METHODS

Russian and English-language publications were analyzed without specifying the search timeframe. The search keywords were the following: «health-resort care», «balneotherapy», «peloid therapy», «physiotherapy», «magnet therapy», «laser therapy» in combination with «dental diseases», «maxillofacial diseases», «periodontal diseases», «temporomandibular joint diseases», «postoperative rehabilitation» «balneotherapy», «mud therapy», «peloid therapy», «spa therapy», «physiotherapy». A total of 21 articles were analyzed, including 10 related to periodontal disease, 5 to temporomandibular joint pathology, and 6 to rehabilitation in the postoperative period. Seventeen original studies (3855 patients) were selected, including 47.62% with evidence level C, due to lack of information on comparison group or randomization.

RESULTS AND DISCUSSION

Available data from clinical studies suggest the effectiveness of natural and physiotherapeutic factors in the medical rehabilitation of patients with various dental diseases. Further randomized clinical trials and the development of clinical guidelines for various techniques in dental diseases are warranted.

Clinical efficacy of medical hydrology: an umbrella review

The aim of this research was to summarize available scientific evidence on the efficacy of medical hydrology for the management of any health condition. The search was conducted on 26th March 2021, in the following databases: Medline (via PubMed), EMBASE, Web of Science, Cochrane Library, and Google Scholar. All relevant literature reviews investigating the clinical efficacy of interventions characterized by the use of natural mineral waters and muds were included. The quality of studies was assessed with the "AMSTAR 2" tool. After article screening, 49 reviews were included in this work. Overall, retrieved scientific evidence suggests that spa therapy is beneficial for patients affected by some specific musculoskeletal conditions, with improvements potentially lasting up to 9 months. Moreover, balneotherapy can be an integrative support for the management of chronic venous insufficiency and some inflammatory skin diseases like psoriasis. The role of spa therapy in rehabilitation appears relevant as well. More limited, although interesting evidence exists for inhalation and hydropinic therapies. Globally, retrieved evidence suggests that, besides individual wellbeing, medical hydrology can be useful for public health. In particular, higher-quality studies seem to support the integrative use of spa-related interventions for conditions like osteoarthritis, fibromyalgia, low back pain of rheumatic origin, and chronic venous insufficiency. However, the body of evidence has some limitations and further clinical trials should be designed for each relevant application to consolidate and expand acquired knowledge.

Endogenous anandamide and self-reported pain are significantly reduced after a 2-week multimodal treatment with and without radon therapy in patients with knee osteoarthritis: a pilot study

Multimodal therapies comprising spa applications are widely used as non-pharmaceutical treatment options for musculoskeletal diseases. The purpose of this randomized, controlled, open pilot study was to elucidate the involvement of the endocannabinoid system in a multimodal therapy approach. Twenty-five elderly patients with knee osteoarthritis (OA) received a 2-week spa therapy with or without combination of low-dose radon therapy in the Bad Gastein radon gallery. A 10-point numerical rating scale (pain in motion and at rest), WOMAC questionnaire, and the EuroQol-5D (EQ-5D) questionnaire were recorded at baseline, and during treatment period at weeks one and two, and at 3-month and 6-month follow-ups. Plasma levels of the endocannabinoid anandamide (AEA) were determined at baseline and at 2 weeks, and serum levels of several cartilage metabolism markers at all five time-points. A significant and sustained reduction of self-reported knee pain was observed in the study population, but no further significant effect of the additional radon therapy up and above base therapy. This pain reduction was accompanied by a significant reduction of AEA plasma levels during treatment in both groups. No significant differences were seen in serum marker concentrations between the groups treated with or without radon, but a small reduction of serum cartilage degradation markers was observed during treatment in both groups. This is the first study investigating AEA levels in the context of a non-pharmacological OA treatment. Since the endocannabinoid system represents a potential target for the development of new therapeutics, further studies will have to elucidate its involvement in OA pain.

The efficacy of balneotherapy, mud therapy and spa therapy in patients with osteoarthritis: an overview of reviews

Osteoarthritis is a degenerative disease considered a leading cause of functional disability. Its treatment is based on a combination of pharmacological and non-pharmacological interventions, but the role of these latter is still debated. This overview of systematic reviews aimed at evaluating the short-term efficacy of different thermal modalities in patients with osteoarthritis. We searched PubMed, Scopus, CINHAL, Web of Science, ProQuest and the Cochrane Database of Systematic Reviews from inception until October 2020, with no language restrictions. We selected the following outcomes a priori: pain, stiffness and quality of life. Seventeen systematic reviews containing 27 unique relevant studies were included. The quality of the reviews ranged from low to critically low. Substantial variations in terms of interventions studied, comparison groups, population, outcomes and follow-up between the included SRs were found. From a re-analysis of primary data, emerged that balneotherapy was effective in reducing pain and improving stiffness and quality of life, mud therapy significantly reduced pain and stiffness, and spa therapy showed pain relief. However, the evidence supporting the efficacy of different thermal modalities could be seriously flawed due to methodological quality and sample size, to the presence of important treatment variations, and to the high level of heterogeneity and the absence of a double-blind design. There is some encouraging evidence that deserves clinicians' consideration, suggesting that thermal modalities are effective on a short-term basis for treating patients with AO.

Therapeutic gases used in balneotherapy and rehabilitation medicine - scientific relevance in the last ten years (2011 – 2020) - Synthetic literature review

ABSTRACT: Background. The medical relevance of therapeutic gases can range from use in burns and stroke victims to hypoxia therapy in children. However, medical gases such as oxygen, hydrogen, helium and xenon have recently come under increased exploration for their potential therapeutic use on various brain disease states, including traumatic brain injuries, hypoxia-ischemia and, cerebral hemorrhages. Objective. This synthetic review aims to rigorously select related articles and identify within their content the main possible uses of therapeutic gases and physiological mechanisms. The objective of this article is to present the various therapeutic mechanisms that have been proposed in the current literature and the medical relevance of various therapeutic gases used in balneotherapy or medical rehabilitation. Methods. To elaborate our synthesis review, we have searched for relevant open access articles in 6 international databases: Cochrane, Elsevier, NCBI/PubMed, NCBI/PMC, PEDro, and ISI Web of Knowledge/Science, published from January 2011 until December 2020. The contextually quested keywords combinations/ syntaxes used specified on this page. The eligible articles were analyzed in detail regarding pathologies addressed by therapeutic gases. All articles with any design (reviews, randomized controlled trials, non-randomized controlled trials, case-control studies, cross-sectional studies), if eligible according to the above-mentioned selection methodology, containing in the title or abstract the above-mentioned combinations, were included in the analysis. Articles were excluded in the second phase if they did not reach the relevance criterion. Results. Our search identified, first, 225 articles. After eliminating the duplicates, remained 180 articles. In the second phase, we applied a relevance criterion. Although our team - including the authors of this paper – have quite long and consistent expertise in achieving systematic literature reviews, the marked heterogeneity of both the item composing the subject we have approached and inherently the wase of presentations in the respective quite vast and diverse domain of medical gases, prevented us to fulfil, at least regarding this initial work, a systematic literature review. Instead, we succeeded to make a hopefully interesting and valuable narrative synthetic-related literature review. At the end of the second phase, 63 articles passed the relevance criterion and were included in this synthetic review. Conclusions. Therapeutic gases are not fully understood and used adequately for sanogenic or medical purposes. More research is needed to fully understand the mechanisms and importance of therapeutic gases. The link between balneotherapy and medical rehabilitation regarding the usage of therapeutical gases emphasises the unity for this medical speciality.

Analysis of the health profiles and prevalence of falls for patients over 65 years of age in a thermal environment

BACKGROUND

A falls prevention programme has been initiated in balneotherapy at Balaruc-les-Bains.

AIMS

To determine the health profiles of subjects who are at risk of falls, over 65 years of age and attending balneotherapy.

METHODS

Questionnaires were used to evaluate people on their fear of falling. Fatigue was assessed by visual analog scale as well as by functional status over the past 12 months. EQ-5D-3L, the IPAQ questionnaire and Fried's frailty scale were all used. Patients' functional capabilities were tested using the Unipedal stance test, the TUG test, the SPPB, the Tandem walking test and the isometric manual grip strength test.

RESULTS

Out of the 1471 patients (72.45 years ± 5.10), the women (67%) were tested. In the last 12 months, 485 of these 1471 patients fell (33%) and 37% of them suffered a severe injury. 45-50% of these subjects are now in good health. Women had a significantly higher impaired perception of their health than men (0.02 < p < 0.0001). According to Fried's criteria, 10.2% of the population is considered frail, with a significantly greater number of women (p < 0.0001). Static equilibrium was subnormal (less than 12 s during the TUG). The number of steps in tandem position discriminates individuals and gender as does the speed of moving from A to B and muscular strength.

CONCLUSIONS

More than one-third of the subjects (more women than men) aged 65 or older visiting the Balaruc-les-Bains health resort are pre-frail or frail. They all have a recent history of falls, suffer from impaired muscle strength, and have balance and gait disorders.

Complementary and Alternative Medicine Use in Rheumatoid Arthritis

PURPOSE OF REVIEW

Despite advances in pharmacologic management of rheumatoid arthritis (RA), complementary and alternative medicine (CAM) remains popular adjuncts to therapy among patients for ongoing symptomatology.

RECENT FINDINGS

Mind-body interventions are becoming increasingly popular, including yoga and meditation. Randomized controlled trials have found these interventions to be helpful regarding pain, mood, and energy in RA patients. Other CAM modalities, such as natural products, special diets, acupuncture, and body-based therapies, also continue to be used by RA patients with limited evidence for efficacy and safety. While there are numerous CAM interventions available, the data is very limited at this time with only low-quality evidence supporting various therapies. Medical providers are more open to the addition of CAM in their patients and require increased education on the topic. Additional research needs to be conducted in order to provide evidence-based recommendations to our patients.

Overview of Systematic Reviews with Meta-Analysis Based on Randomized Controlled Trials of Balneotherapy and Spa Therapy from 2000 to 2019

Background

The objectives of this review were to summarize systematic reviews with meta-analysis of balneotherapy (BT) and spa therapy (ST) based on randomized controlled trials, and to provide a perspective for future research.

Methods

Eligible studies were systematic reviews based on randomized controlled trials with meta-analysis that included at least one group treated with BT or ST. We searched the following databases for articles published in English from the year 2000 to 20 November 2019: Cochrane Database Systematic Review, MEDLINE, CINAHL, Web of Science, and Ichushi-Web.

Results

Eighteen studies met all inclusion criteria. Based on the International Classification of Diseases (ICD)-11, among these 18 studies, 8 (44%) were about “#15 Diseases of the musculoskeletal system or connective tissue”, 5 (28%) were about “#21 Symptoms, signs or clinical findings, not elsewhere classified”, 4 (22%) were about “#11 Diseases of the circulatory system”, and 1 study (6%) was about “#8 Diseases of the nervous system”. Both BT and ST provided significant pain relief and improved quality of life in chronic diseases of the musculoskeletal system and connective tissues. Additionally, BT and ST with exercise under water improved physical fitness and function in patients across diseases.

Conclusion

Researchers need to conduct studies on the treatment of many kinds of potential diseases using the keywords of pain relief and QoL. In addition, depending on patients’ symptoms, physical fitness, and disabilities, performing exercise under water may improve treatment effects on physical function and fitness.

Traditional Chinese herbal bath therapy for insomnia: A protocol for systematic review

INTRODUCTION

Insomnia is a major public health problem. Due to the side effects of pharmacological therapy, people are seeking to choose complementary and alternative therapies for insomnia disorder. Traditional Chinese herbal bath therapy is an important complementary therapy which combines advantages of Chinese herbs and bathing therapy. This protocol describes the methodology of a systematic review assessing the effectiveness and safety of traditional Chinese herbal bath therapy for insomnia.

METHODS AND ANALYSIS

Reporting of this review will be adherent to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We will electronically search the following seven databases from inception to January 23, 2020: PubMed, Cochrane database (CENTRAL), EMBASE, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), VIP Database, and Wanfang Database. Parallel randomized controlled trials evaluating the effectiveness and safety of traditional Chinese herbal bath therapy for insomnia will be included. Study selection, data extraction and assessment of risk of bias will be performed independently by two researchers. The sleep quality will be assessed as the primary outcome. Global symptom improvement, anxiety and depression, and adverse events will be evaluated as secondary outcomes. The Cochrane's risk of bias tool will be utilized for assessing the methodological quality of included studies. Revman software (v.5.3) will be used for data synthesis and statistical analysis. Data will be synthesized by either fixed-effects or random-effects model according to a heterogeneity test. If it is not appropriate for a meta-analysis, a descriptive analysis will be conducted. GRADE system will be used to assess the quality of evidence.

The effect of balneotherapy and peloid therapy on changes in the functional state of patients with knee joint osteoarthritis: a randomized, controlled, single-blind pilot study

The treatment of OA using pharmaceutical and non-pharmaceutical measures remains a topical subject. The purpose of this study is to assess the effect of natural factors (mineral water and mud) on changes in the functional state of patients with knee joint OA. Ninety-two adult people with grade I-III knee joint OA according to the Kellgren and Lawrence scoring system participated in the study. The subjects received 10 mineral water bath plus physical therapy or mud application procedures plus physical therapy or physical therapy alone every other day. The effectiveness of the treatment was assessed on the basis of anthropometric changes of data, VAS, SF-36, KOOS questionnaire indicators. Significantly greater walking speed, test of 5 sit downs/stand ups, circumference of a knee joint, flexion and extension range, flexor and extensor strength after treatment lasting 1 month were obtained in the intervention group. After 1 month after treatment pain intensity scores over the past month and when changing position were significantly higher in the control group. The positive changes in SF-36 were identified after 1 month after treatment: physical activity increased and pain decreased in the intervention groups. There was no significant difference between the averages of any KOOS subscale in groups. However, average percentages of symptoms, stiffness, and pain in the intervention groups were significantly better after treatment and lasting 1 month after treatment. Balneotherapy and peloid therapy effectively reduce pain and improve the functional state of patients with OA of a knee joint.

Comparative Study of SPA Mud from "Bacino Idrominerario Omogeneo dei Colli Euganei (B.I.O.C.E.)-Italy" and Industrially Optimized Mud for Skin Applications

The term "Salus per aquam (SPA) therapies" refers to therapeutic pathways that includes mud therapy. The therapeutic efficacy of a peloid depends on its chemical and mineralogical composition, as well as its technological properties. Considering the increasing use of clay-based products, it becomes essential to characterize peloids from a qualitative and quantitative point of view. Therefore, this research project aimed to develop a protocol that allows characterization of the chemical-physical composition of sludges collected from different areas of the Homogeneous Euganean Hills Hydromineral Basin (B.I.O.C.E.). The study established a comparative study both between different matrices and between the same matrices at different maturation times, including also a comparison with an industrialized product, that can be used at home, which maintains the characteristics of a natural mud. This research was developed studying the pH, grain size distribution, and chemical and mineralogical composition. Peloids are characterized by a neutral/basic pH and are divided into two categories from a granulometric point of view: The chemical composition allowed observation of numerous correlations between oxides present in the samples and to quantify the presence of heavy metals. Mineralogical analysis made it possible to identify and compare the composition of each sample, also according to the maturation time. Thanks to the methods adopted, important correlations were achieved.

Mud therapy and rehabilitation - scientific relevance in the last six years (2015 – 2020) Systematic literature review and meta-analysis based on the PRISMA paradigm

Abstract Background. Balneotherapy is a stimulation - adaptation treatment method applied in the forms of bathing, drinking, and inhalation cures performed with natural therapeutic factors, a method which is acting in three main ways: thermally, mechanically, and chemically. Mud or peloids are natural therapeutic factors formed by natural processes under the influence of biological and geological phenomena, which in a finely dissolved state and mixed with water (mud) are used in medical practice in the form of baths or local procedures. Objective. This systematic review aims to rigorously select related articles and identify within their content, the main possible uses of therapeutic mud and physiological mechanisms, to see the main region of scientific interest for pelotherapy, and to discuss the value of mud therapy in rehabilitation medicine. Methods. The working method is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched for open-access articles published in English, between January 2015 and December 2020, from the following databases: Cochrane, Elsevier, NCBI/PubMed, NCBI/PMC, PEDro, and ISI Web of Knowledge/Science (the latter was also used to identify ISI indexed articles). The contextually searched syntax used was ”Pelotherapy/Peloidotherapy/Mud-therapy/ /Fango-therapy AND Rehabilitation”. The selected articles were analyzed in detail regarding pathologies addressed by mud therapy and country scientific relevance for this therapeutic method. The meta-analysis proceeded was designated to estimate the prevalence of various pathologies in the use of mud therapy. Results. Our search identified, first, 394 articles. Based on the successive filtering stages and, respectively, on the classification criteria of the Physiotherapy Evidence Database (PEDro), we finally identified/retained and analyzed 68 articles. Although, in principle, a rigorous method – and we have followed the PRISMA type paradigm – there still might be some missing works of our related article selection. On the other hand, to augment/ consolidate our documentation base, we have used also 40 papers freely found in the literature, and even – aiming, too, at an as exhaustive knowledge underpinning as possible – derogatively, we have also considered some articles which, probably being very new, couldn't yet have reached the PEDro threshold score we have settled. Conclusions. This paper overviews the current state-of-the-art knowledge in the approach of peloidotherapy in rehabilitation, with a focal point on the therapeutic properties of peloids. Keywords: mud-therapy, pelotherapy, peloidotherapy, fango therapy, rehabilitation, balneotherapy, natural therapeutic factors,

Balneotherapy for chronic venous insufficiency

BACKGROUND

Chronic venous insufficiency (CVI) is a progressive and common disease that affects the superficial and deep venous systems of the lower limbs. CVI is characterised by valvular incompetence, reflux, venous obstruction, or a combination of these with consequent distal venous hypertension. Clinical manifestations of CVI include oedema, pain, skin changes, ulcerations and dilated skin veins in the lower limbs. It can result in a large financial burden on health systems. There is a wide variety of treatment options or therapies for CVI, ranging from surgery and medication to compression and physiotherapy. Balneotherapy (treatments involving water) is a relatively cheap option and potentially efficient way to deliver physical therapy for people with CVI.

OBJECTIVES

To assess the efficacy and safety of balneotherapy for the treatment of people with chronic venous insufficiency (CVI).

SEARCH METHODS

The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, AMED and CINAHL databases, the World Health Organization International Clinical Trials Registry Platform and the Clinical Trials.gov trials register to August 2018. We searched the LILACS and IBECS databases. We also checked references, searched citations and contacted study authors to identify additional studies.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials comparing balneotherapy with no treatment or other types of treatment for CVI. We also included studies that used a combination of treatments.

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed studies retrieved by the search strategies. Both review authors independently assessed selected studies for complete analysis. We resolved conflicts through discussion. We attempted to contact trial authors for missing data, obtaining additional information. For binary outcomes (leg ulcer incidence and adverse events), we presented the results using odds ratio (OR) with 95% confidence intervals (CI). For continuous outcomes (disease severity, health-related quality of life (HRQoL), pain, oedema, skin pigmentation), we presented the results as a mean difference (MD) with 95% CI.

MAIN RESULTS

We included seven randomised controlled trials with 891 participants (outpatients in secondary care). We found no quasi-randomised controlled trials. Six studies (836 participants) evaluated balneotherapy versus no treatment. One study evaluated balneotherapy versus a phlebotonic drug (melilotus officinalis) (55 participants). There was a lack of blinding of participants and investigators, imprecision and inconsistency, which downgraded the certainty of the evidence.For the balneotherapy versus no treatment comparison, there probably was no improvement in favour of balneotherapy in disease severity signs and symptom score as assessed using the Venous Clinical Severity Score (VCSS) (MD -1.66, 95% CI -4.14 to 0.83; 2 studies, 484 participants; moderate-certainty evidence). Balneotherapy probably resulted in a moderate improvement in HRQoL as assessed by the Chronic Venous Insufficiency Questionnaire 2 (CVIQ2) at three months (MD -9.38, 95% CI -18.18 to -0.57; 2 studies, 149 participants; moderate-certainty evidence), nine months (MD -10.46, 95% CI -11.81 to -9.11; 1 study; 55 participants; moderate-certainty evidence), and 12 months (MD -4.99, 95% CI -9.19 to -0.78; 2 studies, 455 participants; moderate-certainty evidence). There was no clear difference in HRQoL between balneotherapy and no treatment at six months (MD -1.64, 95% CI -9.18 to 5.89; 2 studies, 445 participants; moderate-certainty evidence). Balneotherapy probably slightly improved pain compared with no treatment (MD -1.23, 95% CI -1.33 to -1.13; 1 study; 390 participants; moderate-certainty evidence). There was no clear effect related to oedema between the two groups at 24 days (MD 43.28 mL, 95% CI -102.74 to 189.30; 2 studies, 153 participants; very-low certainty evidence). There probably was no improvement in favour of balneotherapy in the incidence of leg ulcers (OR 1.69, 95% CI 0.82 to 3.48; 2 studies, 449 participants; moderate-certainty evidence). There was probably a reduction in incidence of skin pigmentation changes in favour of balneotherapy at 12 months (pigmentation index: MD -3.59, 95% CI -4.02 to -3.16; 1 study; 59 participants; low-certainty evidence). The main complications reported included erysipelas (OR 2.58, 95% CI 0.65 to 10.22; 2 studies, 519 participants; moderate-certainty evidence), thromboembolic events (OR 0.35, 95% CI 0.09 to 1.42; 3 studies, 584 participants; moderate-certainty evidence) and palpitations (OR 0.33, 95% CI 0.01 to 8.52; 1 study; 59 participants; low-certainty evidence), with no clear evidence of an increase in reported adverse effects with balneotherapy. There were no serious adverse events reported in any of the studies.For the balneotherapy versus a phlebotonic drug (melilotus officinalis) comparison, we observed no clear difference in pain symptoms (OR 0.29, 95% CI 0.03 to 2.87; 1 study; 35 participants; very low-certainty evidence) and oedema (OR 0.21, 95% CI 0.02 to 2.27; 1 study; 35 participants; very low-certainty evidence). This single study did not report on the other outcomes of interest.

AUTHORS' CONCLUSIONS

We identified moderate- to low-certainty evidence that suggests that balneotherapy may result in a moderate improvement in pain, quality of life and skin pigmentation changes and has no clear effect on disease severity signs and symptoms score, adverse effects, leg ulcers and oedema when compared with no treatment. For future studies, measurements of outcomes such as disease severity sign and symptom score, quality of life, pain and oedema and choice of time points during follow-up must be standardised for adequate comparison between trials.

The Thermal Effects of Water Immersion on Health Outcomes: An Integrative Review

Hydrotherapy is widely used for the treatment and rehabilitation of patients, but it can also be applied to prevent diseases in healthy people. This review investigates the health effects of water immersion, a form of hydrotherapy, and the mechanisms by which the properties of water elicit such an effect. We searched PubMed, EMBASE, Cochrane Library, and CINAHL to identify relevant articles, of which 13 met the inclusion criteria. Various factors of water immersion were investigated in the 13 selected articles, including water temperature, immersion height, and application area. With respect to health effects, warm and cold water immersion affects the cardiovascular and neuromuscular systems, respectively. Nine articles focused on the effects of warm water immersion, explaining its thermal effect in relation to changes in disease-related serum substance levels and hemodynamic changes. While the sample population in most studies comprised young adults, two articles applied partial water immersion to the legs of elderly subjects to assess its effect on sleep. Because the water immersion protocols applied in the 13 articles were inconsistent, the health benefits could not be clearly explained. However, we expect the present findings to be beneficial for providing research guidelines for studies on the application of water immersion.

[The specific methodological features of scientific research in the field of balneotherapy]

This review was undertaken for the objective of highlighting and assessing the approaches to obtaining, analysis, and reporting the results of randomized controlled trials (RCT) in balneotherapy. The review covers the following topics: the specific features of the organization of the controlled randomized studies in the field of balneotherapy, the main methodological approaches used for these purposes that should be taken into consideration at different stages of the planning and performance of the studies together with other issues including sample size calculation, sequence generation modes, the application of the distribution concealment technique, types of randomization, blinding of the outcome assessment, the choice of the comparator group, and endpoint selection. We emphasize the importance of the appropriate statistical analysis and the comprehensive reporting of the results of the investigations. Special attention is given to the current approaches to the estimation of the quality of RCTs and to the preparation of the systematic reviews. The examples of the analysis of the relevant publications presented in the review will hopefully help the researchers to take advantage of the currently available experience and improve the compliance of the locally conducted balneotherapeutic trials with the international criteria for the methodological quality.

Scoping review of systematic reviews of complementary medicine for musculoskeletal and mental health conditions

OBJECTIVE

To identify potentially effective complementary approaches for musculoskeletal (MSK)-mental health (MH) comorbidity, by synthesising evidence on effectiveness, cost-effectiveness and safety from systematic reviews (SRs).

DESIGN

Scoping review of SRs.

METHODS

We searched literature databases, registries and reference lists, and contacted key authors and professional organisations to identify SRs of randomised controlled trials for complementary medicine for MSK or MH. Inclusion criteria were: published after 2004, studying adults, in English and scoring >50% on Assessing the Methodological Quality of Systematic Reviews (AMSTAR); quality appraisal checklist). SRs were synthesised to identify research priorities, based on moderate/good quality evidence, sample size and indication of cost-effectiveness and safety.

RESULTS

We included 84 MSK SRs and 27 MH SRs. Only one focused on MSK-MH comorbidity. Meditative approaches and yoga may improve MH outcomes in MSK populations. Yoga and tai chi had moderate/good evidence for MSK and MH conditions. SRs reported moderate/good quality evidence (any comparator) in a moderate/large population for: low back pain (LBP) (yoga, acupuncture, spinal manipulation/mobilisation, osteopathy), osteoarthritis (OA) (acupuncture, tai chi), neck pain (acupuncture, manipulation/manual therapy), myofascial trigger point pain (acupuncture), depression (mindfulness-based stress reduction (MBSR), meditation, tai chi, relaxation), anxiety (meditation/MBSR, moving meditation, yoga), sleep disorders (meditative/mind-body movement) and stress/distress (mindfulness). The majority of these complementary approaches had some evidence of safety-only three had evidence of harm. There was some evidence of cost-effectiveness for spinal manipulation/mobilisation and acupuncture for LBP, and manual therapy/manipulation for neck pain, but few SRs reviewed cost-effectiveness and many found no data.

CONCLUSIONS

Only one SR studied MSK-MH comorbidity. Research priorities for complementary medicine for both MSK and MH (LBP, OA, depression, anxiety and sleep problems) are yoga, mindfulness and tai chi. Despite the large number of SRs and the prevalence of comorbidity, more high-quality, large randomised controlled trials in comorbid populations are needed.

Spa therapy adjunct to pharmacotherapy is beneficial in rheumatoid arthritis: a crossover randomized controlled trial

This study aims to investigate whether 2-week spa therapy, as an adjunct to usual pharmacological therapy, has any beneficial effect in patients with rheumatoid arthritis (RA). In this single-blind crossover study, 50 patients were randomly assigned in a 1:1 manner to receive usual pharmacological therapy plus 2-week spa therapy or usual pharmacological therapy alone (period 1.6 months); after a 9-month washout, patients were crossed over to the opposite assignment (period 2.6 months). Spa therapy program included a daily saline balneotherapy session at 36-37 °C for 20 min except Sundays. The clinical outcomes were evaluated at baseline, after spa therapy (2 weeks) and 3 and 6 months after the spa therapy in both period and were pain (Visual Analogue Scale (VAS)), patient and physician global assessments (VAS), Health Assessment Questionnaire (HAQ), and Disease Activity Score (DAS28). Spa therapy was superior to control therapy in improving all the assessed clinical outcomes at the end of the spa therapy. This superiority persisted significantly in physician global assessment (p = 0.010) and with a trend in favor of spa group in patient global assessment (p = 0.058), function (p = 0.092), and disease activity (p = 0.098) at 3 months. Statistically significant improvements were found in spa therapy compared to control in disease activity (p = 0.006) and patient (p = 0.020) and physician global (p = 0.011) assessments, and a trend toward improvements in pain (p = 0.069) and swollen joints (p = 0.070) at 6 months. A 2-week spa therapy adjunct to usual pharmacological therapy provided beneficial clinical effects compared to usual pharmacological therapy alone, in RA patients treated with traditional disease-modifying antirheumatic drugs. These beneficial effects may last for 6 months.

The role of mineral elements and other chemical compounds used in balneology: data from double-blind randomized clinical trials

The aims of this study were to conduct a systematic literature review on balneotherapy about the specific therapeutic role of mineral elements and other chemical compounds of mineral waters and derivate peloids/muds and to discuss the study methods used to evaluate it (in musculoskeletal conditions). We searched Medline by PubMed using the following key words: "spa therapy" "balneotherapy" "mud" "peloid" "mud pack Therapy" in combination with "randomized controlled trial" "double blind trial." We also reviewed the reference list of articles retrieved by the Medline search. We selected the double-blind randomized clinical trials that assessed the effects of mineral water or mud treatments compared to tap water, attenuated peloid/mud therapy or similar treatments without the specific minerals or chemical compounds of the treatment group ("non-mineral"). We evaluated the internal validity and the quality of the statistical analysis of these trials. The final selection comprised 27 double-blind randomized clinical trials, 20 related to rheumatology. A total of 1118 patients with rheumatological and other musculoskeletal diseases were evaluated in these studies: 552 of knee osteoarthritis, 47 of hand osteoarthritis, 147 chronic low back pain, 308 of reumathoid arthritis, and 64 of osteoporosis; 293 of these participants were assigned to the experimental groups of knee osteoarthritis, 24 in hand osteoarthritis, 82 of low back pain, 152 with reumathoid arthritis, and 32 with osteoporosis. They were treated with mineral water baths and/or mud/peloid (with or without other forms of treatment, like physical therapy, exercise…). The rest were allocated to the control groups; they received mainly tap water and/or "non-mineral" mud/peloid treatments. Mineral water or mud treatments had better and longer improvements in pain, function, quality of life, clinical parameters, and others in some rheumatologic diseases (knee and hand osteoarthritis, chronic low back pain, rheumatoid arthritis, and osteoporosis) compared to baseline and non-mineral similar treatments. Internal validity and other limitations of the study's methodology impede causal relation of spa therapy on these improvements. Randomized clinical trials are very heterogeneous. Double-blind randomized clinical trials seem to be the key for studying the role of mineral elements and other chemical compounds, observing enough consistency to demonstrate better and longer improvements for mineral waters or derivate compared to tap water; but due to heterogeneity and gaps on study protocol and methodology, existing research is not sufficiently strong to draw firm conclusions. Well-designed studies in larger patients' population are needed to establish the role of minerals and other chemical compounds in spa therapy.

Celecoxib for rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis is a systemic auto-immune disorder that causes widespread and persistent inflammation of the synovial lining of joints and tendon sheaths. Presently, there is no cure for rheumatoid arthritis and treatment focuses on managing symptoms such as pain, stiffness and mobility, with the aim of achieving stable remission and improving mobility. Celecoxib is a selective non-steroidal anti-inflammatory drug (NSAID) used for treatment of people with rheumatoid arthritis.

OBJECTIVES

To assess the benefits and harms of celecoxib in people with rheumatoid arthritis.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase and clinical trials registers (ClinicalTrials.gov and the World Health Organization trials portal) to May 18, 2017. We also searched the reference and citation lists of included studies.

SELECTION CRITERIA

We included prospective randomized controlled trials (RCTs) that compared oral celecoxib (200 mg and 400 mg daily) versus no intervention, placebo or a traditional NSAID (tNSAID) in people with confirmed rheumatoid arthritis, of any age and either sex. We excluded studies with fewer than 50 participants in each arm or had durations of fewer than four weeks treatment.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by The Cochrane Collaboration.

MAIN RESULTS

We included eight RCTs with durations of 4 to 24 weeks, published between 1998 and 2014 that involved a total of 3988 adults (mean age = 54 years), most of whom were women (73%). Participants had rheumatoid arthritis for an average of 9.2 years. All studies were assessed at high or unclear risk of bias in at least one domain. Overall, evidence was assessed as moderate-to-low quality. Five studies were funded by pharmaceutical companies. Celecoxib versus placeboWe included two studies (N = 873) in which participants received 200 mg daily or 400 mg daily or placebo. Participants who received celecoxib showed significant clinical improvement compared with those receiving placebo (15% absolute improvement; 95% CI 7% to 25%; RR 1.53, 95% CI 1.25 to 1.86; number needed to treat to benefit (NNTB) = 7, 95% CI 5 to 13; 2 studies, 873 participants; moderate to low quality evidence).Participants who received celecoxib reported less pain than placebo-treated people (11% absolute improvement; 95% CI 8% to 14%; NNTB = 4, 95% CI 3 to 6; 1 study, 706 participants) but results were inconclusive for improvement in physical function (MD -0.10, 95% CI 0.29 to 0.10; 1 study, 706 participants).In the celecoxib group, 15/293 participants developed ulcers, compared with 4/99 in the placebo group (Peto OR 1.26, 95% CI 0.44 to 3.63; 1 study, 392 participants; low quality evidence). Nine (of 475) participants in the celecoxib group developed short-term serious adverse events, compared with five (of 231) in the placebo group (Peto OR 0.87 (0.28 to 2.69; 1 study, 706 participants; low quality evidence).There were fewer withdrawals among people who received celecoxib (163/475) compared with placebo (130/231) (22% absolute change; 95% CI 16% to 27%; RR 0.61, 95% CI 0.52 to 0.72; 1 study, 706 participants).Cardiovascular events (myocardial infarction, stroke) were not reported. However, regulatory agencies warn of increased cardiovascular event risk associated with celecoxib. Celecoxib versus tNSAIDsSeven studies (N = 2930) compared celecoxib and tNSAIDs (amtolmetin guacyl, diclofenac, ibuprofen, meloxicam, nabumetone, naproxen, pelubiprofen); one study included comparisons of both placebo and tNSAIDs (N = 1149).There was a small improvement, which may not be clinically significant, in numbers of participants achieving ACR20 criteria response in the celecoxib group compared to tNSAIDs (4% absolute improvement; 95% CI 0% less improvement to 8% more improvement; RR 1.10, 95% CI 0.99 to 1.23; 4 studies, 1981 participants). There was a lack of evidence of difference between participants in the celecoxib and tNSAID groups in terms of pain or physical function. Results were assessed at moderate-to-low quality evidence (downgraded due to risk of bias and inconsistency).People who received celecoxib had a lower incidence of gastroduodenal ulcers ≥ 3 mm (34/870) compared with those who received tNSAIDs (116/698). This corresponded to 12% absolute change (95% CI 11% to 13%; RR 0.22, 95% CI 0.15 to 0.32; 5 studies, 1568 participants; moderate quality evidence). There were 7% fewer withdrawals among people who received celecoxib (95% CI 4% to 9%; RR 0.73, 95% CI 0.62 to 0.86; 6 studies, 2639 participants).Results were inconclusive for short-term serious adverse events and cardiovascular events (low quality evidence). There were 17/918 serious adverse events in people taking celecoxib compared to 42/1236 among people who received placebo (Peto OR 0.71; 95% CI 0.39 to 1.28; 5 studies, 2154 participants). Cardiovascular events were reported in both celecoxib and placebo groups in one study (149 participants).

AUTHORS' CONCLUSIONS

Celecoxib may improve clinical symptoms, alleviate pain and contribute to little or no difference in physical function compared with placebo. Celecoxib was associated with fewer numbers of participant withdrawals. Results for incidence of gastroduodenal ulcers (≥ 3 mm) and short-term serious adverse events were uncertain; however, there were few reported events for either.Celecoxib may slightly improve clinical symptoms compared with tNSAIDs. Results for reduced pain and improved physical function were uncertain. Particpants taking celecoxib had lower incidence of gastroduodenal ulcers (≥ 3 mm) and there were fewer withdrawals from trials. Results for cardiovascular events and short-term serious adverse events were also uncertain.Uncertainty about the rate of cardiovascular events between celecoxib and tNSAIDs could be due to risk of bias; another factor is that these were small, short-term trials. It has been reported previously that both celecoxib and tNSAIDs increase cardiovascular event rates. Our confidence in results about harms is therefore low. Larger head-to-head clinical trials comparing celecoxib to other tNSAIDs is needed to better inform clinical practice.

Psychometric properties of the painDETECT questionnaire in rheumatoid arthritis, psoriatic arthritis and spondyloarthritis: Rasch analysis and test-retest reliability

Background

Pain is inherent in rheumatoid arthritis (RA), psoriatic arthritis (PsA) and spondyloarthritis (SpA) and traditionally considered to be of nociceptive origin. Emerging data suggest a potential role of augmented central pain mechanisms in subsets of patients, thus, valid instruments that can identify underlying pain mechanisms are needed. The painDETECT questionnaire (PDQ) was originally designed to differentiate between pain phenotypes. The objectives were to evaluate the psychometric properties of the PDQ in patients with inflammatory arthritis by applying Rasch analysis and to explore the reliability of pain classification by test-retest.

Methods

For the Rasch analysis 900 questionnaires from patients with RA, PsA and SpA (300 per diagnosis) were extracted from ‘the DANBIO painDETECT study’. The analysis was directed at the seven items assessing somatosensory symptoms and included: 1) the performance of the six-category Likert scale; 2) whether a unidimensional construct was defined; 3) the reliability and precision of estimates. Another group of 30 patients diagnosed with RA, PsA or SpA participated in a test-retest study. Intraclass Correlation Coefficients (ICC) and classification consistency were calculated.

Results

The Rasch analysis revealed: (1) Acceptable psychometric rating scale properties; the frequency distribution peaked in category 0 except for item 5, threshold calibration >10 observations per category, no disorder in the category measures for all items, scale category outfit Mnsq <2.0, small distances (<1.4 logits) between thresholds for category 1, 2 and 3 for all items. (2) The principal component analysis supported unidimensionality; the standardized residuals showed that 53.7% of total variance was explained by the measure and the magnitude of first contrast had an eigenvalue of 1.5, no misfitting items, clinical insignificant different item hierarchies across diagnoses (DIF < 0.5 logits). (3) A targeted item-person map, person and item separation indices of 1.88(reliability = 0.78), and 13.04 (reliability = 0.99). The test-retest revealed: ICC: RA 0.86(0.56–0.96), PsA 0.96(0.74–0.99), SpA 0.93(0.76–98), overall 0.94(0.84–0.98). Classification consistency was: RA 70%, PsA 80%, SpA 90%, overall 80%.

Conclusion

The results support that the PDQ can be used as a classification instrument and assist identification of underlying pain-mechanisms in patients suffering from inflammatory arthritis.

Effect of spa therapy with saline balneotherapy on oxidant/antioxidant status in patients with rheumatoid arthritis: a single-blind randomized controlled trial

Oxidative stress has been shown to play a contributory role in the pathogenesis of rheumatoid arthritis (RA). Recent studies have provided evidence for antioxidant properties of spa therapy. The purpose of this study is to investigate whether spa therapy with saline balneotherapy has any influence on the oxidant/antioxidant status in patients with RA and to assess clinical effects of spa therapy. In this investigator-blind randomized controlled trial, we randomly assigned 50 patients in a 1:1 ratio to spa therapy plus standard drug treatment (spa group) or standard drug treatment alone (control group). Spa group followed a 2-week course of spa therapy regimen consisting of a total of 12 balneotherapy sessions in a thermal mineral water pool at 36-37 °C for 20 min every day except Sunday. All clinical and biochemical parameters were assessed at baseline and after spa therapy (2 weeks). The clinical parameters were pain intensity, patient global assessment, physician global assessment, Health Assessment Questionnaire disability index (HAQ-DI), Disease Activity Score for 28-joints based on erythrocyte sedimentation rate (DAS28-4[ESR]). Oxidative status parameters were malondialdehyde (MDA), nonenzymatic superoxide radical scavenger activity (NSSA), antioxidant potential (AOP), and superoxide dismutase (SOD). The NSSA levels were increased significantly in the spa group (p = 0.003) but not in the control group (p = 0.509); and there was a trend in favor of spa therapy for improvements in NSSA levels compared to control (p = 0.091). Significant clinical improvement was found in the spa group compared to the control in terms of patient global assessment (p = 0.011), physician global assessment (p = 0.043), function (HAQ-DI) (p = 0.037), disease activity (DAS28-4[ESR]) (0.044) and swollen joint count (0.009), and a trend toward improvement in pain scores (0.057). Spa therapy with saline balneotherapy exerts antioxidant effect in patients with RA as reflected by the increase in NSSA levels after spa therapy; whether this antioxidant effect contributes to the clinical improvements observed remains to be verified.

Evaluation of the efficacy of a short-course, personalized self-management and intensive spa therapy intervention as active prevention of musculoskeletal disorders of the upper extremities (Muska): a research protocol for a randomized controlled trial

Background

Musculoskeletal disorders (MSDs) constitute a major occupational health problem in the working population, substantially impacting the quality of life of employees. They also cause considerable economic cost to the healthcare system, with, notably, the reimbursement of treatments and compensation for lost income. MSDs manifest as localized pain or functional difficulty in one or more anatomical areas, such as the cervical spine, shoulder, elbow, hand, and wrist. Although prevalence varies depending on the region considered and the method of assessment, a prevalence of 30% is found in different epidemiological studies. The disease needs to be prevented, not only for medical and economic reasons, but also for legal reasons, owing to the requirement of assessing occupational risks. The strategy envisaged may thus revolve around active, multimodal prevention that has employees fully involved at the heart of their care. Although physical exercise is widely recommended, few studies with a good level of evidence have enabled us to base a complete, well-constructed intervention on exercise that can be offered as secondary prevention in these disorders.

Methods

A prospective, multicenter, comparative (intervention arm vs. control arm), randomized (immediate vs. later treatment) study using Zelen’s design. This study falls under active prevention of MSDs of the upper extremities (UE-MSDs). Participants are workers aged between 18 and 65 years with latent or symptomatic MSDS, with any type of job or workstation, with or without an history of sick leave. The primary aim is to show the superiority at 3 months of a combination of spa therapy, exercise, and self-management workshops for 6 days over usual care in the management of MSDs in terms of employee functional capacity in personal and professional daily life. Secondary aims are to assess the benefit of the intervention in terms of pain, quality of life, and accumulated duration of sick leave.

Discussion

This randomized controlled trial is the first that will aim to evaluate multidisciplinary management of UE-MSDs using nonpharmacological treatment combining exercise, self-management, and spa therapy. The originality of this intervention lies, in its short, intensive format, which is compatible with remaining in work; and in its multidisciplinary approach. This trial has the potential to demonstrate, with a good level of evidence, the benefits of a short course of spa therapy combined with a personalized self-management program on the functional capacity, pain, and quality of life of employees in their daily life.

A comparison of Kneipp hydrotherapy with conventional physiotherapy in the treatment of osteoarthritis of the hip or knee: protocol of a prospective randomised controlled clinical trial

BACKGROUND

The increasing age of the population, especially in the western world, means that the prevalence of osteoarthritis is also increasing, with corresponding socioeconomic consequences. Although there is no curative intervention at present, in accordance with US and European guidelines, pharmacotherapeutic and non-pharmacological approaches aim at pain control and the reduction of functional restriction.It has been established that hydrotherapy for osteoarthritis of the hip or knee joint using serial cold and warm water stimulation not only improves the range of movement but also reduces pain significantly and increases quality of life over a period of up to three months. Weight reduction is important for patients with osteoarthritis of the hip or knee. In addition, conventional physiotherapy and exercise therapy have both been shown, at a high level of evidence, to be cost-effective and to have long-term benefits for pain relief, movement in the affected joint, and patient quality of life.

METHODS/DESIGN

The study design consists of a prospective randomised controlled three-armed clinical trial, which will be carried out at a specialist clinic for integrative medicine, to investigate the clinical effects of hydrotherapy on osteoarthritis of the knee or hip joint, in comparison with conventional physiotherapy.One hundred and eighty patients diagnosed with osteoarthritis of hip or knee will be randomly assigned to one of three intervention groups: hydrotherapy, physiotherapy, and both physiotherapy and hydrotherapy of the affected joint. In the first group, patients will receive Kneipp hydrotherapy daily, with water applied in the form of alternate cold and warm thigh affusions (alternating cold and warm water stimulation is particularly relevant to the knee and hip regions).Patients in the second group will receive physiotherapy of the hip or knee joint three times a week. Patients in the physiotherapy-hydrotherapy combination group will receive both joint-specific physiotherapy three times a week and alternate cold and warm thigh affusions every day. Follow-up assessments will be on three levels: clinical assessment by the investigator; subjective patient assessment consisting of a patient diary, and questionnaires on admission and at the end of the treatment phase; and a final telephone assessment by the external evaluation centre. Assessments will be made at baseline, after two weeks of inpatient treatment, and finally after a further ten weeks of follow-up. The primary outcome measure will be pain intensity of the affected joint in the course of inpatient treatment, judged by the patient and the investigator. Secondary outcomes include health-related quality of life and joint-specific pain and mobility in the course of the study. Statistical analysis of the results will be on an intention-to-treat basis.

CONCLUSION

This study methodology has been conceived according to the standards of the CONSORT recommendations. The results will contribute to establishing hydrotherapy as a non-invasive, non-interventional, reasonably priced, therapeutic option with few side effects, in the concomitant treatment of osteoarthritis of the hip or knee.

Effectiveness of comprehensive health education combining lifestyle education and hot spa bathing for male white-collar employees: a randomized controlled trial with 1-year follow-up

BACKGROUND

Physical activity is known to prevent obesity and metabolic syndrome in middle-aged and elderly people; however, the effectiveness of a comprehensive health education program for male white-collar employees is uncertain.

METHODS

Forty-three men volunteered to participate in this study and were randomly assigned into 2 groups. The intervention group participated in a 2-hour program comprising comprehensive health education and hot spa bathing, offered once every 2 weeks, in addition to individualized programs once a week, for 24 weeks. The control group received only general health guidance. We compared their lifestyle characteristics and physical and mental health criteria at baseline, immediately after the intervention, and 1 year after the end of the intervention.

RESULTS

Rates of adherence to individualized programs were 60.0 +/- 27.2% and 30.5 +/- 29.6% at the end of the intervention and at 1 year after the end of the intervention, respectively. Significant (P < 0.05) interaction of criteria was observed for cluster of differentiation 4+ (CD4+) cells and the ratio of cluster of differentiation 4+ to 8+ (CD4/8) cells, which were used to represent the participants' immunological function. We divided the intervention group into 2 subgroups on the basis of their attendance. Among the resulting 3 groups, significant interaction of criteria was observed for CD4+ and CD4/8 cells. In addition, the high attendance group had the highest CD4+ count and CD4/8 ratio.

CONCLUSIONS

Participants who attended classes and/or performed the supplementary individualized programs tended to maintain their immunological function and to experience a decrease in body fat percentage. However, few effects were noted in participants with poor adherence, even in the intervention group.

[Evidence-based physiotherapeutic strategies for musculoskeletal pain]

Inflammatory rheumatic disorders usually progress towards morphologic and functional deficits and thus cause substantial impairment of physical health. Amongst the therapeutic options physiotherapeutic strategies are essential and are often required to maintain the individual's quality of life. Because of the large variety of physiotherapeutical approaches, differentiated clinical examination is needed in order to implement physiotherapeutics in a treatment plan that is based on pathophysiologic and regeneration-specific aspects. The article presents a current overview of evidence-based physiotherapeutic strategies for musculoskeletal pain reduction in daily practice.
