28148754 | Explanatory Style in Patients with Rheumatoid Arthritis: An Unrecognized Predictor of Mort | 2017 Feb | OBJECTIVE: To determine whether pessimistic explanatory style altered the risk for and mortality of patients with rheumatoid arthritis (RA). METHODS: The study included subjects from a population-based cohort with incident RA and a non-RA comparison cohort who completed the Minnesota Multiphasic Personality Inventory. RESULTS: Among 148 RA and 135 non-RA subjects, pessimism was associated with development of rheumatoid factor (RF)-positive RA. Pessimism was associated with an increased risk of mortality [HR 2.88 with similar magnitude to RF+ (HR 2.28)]. CONCLUSION: Pessimistic explanatory style was associated with an increased risk of developing RA and increased mortality rate in patients with RA. | |
28124094 | Pain rather than self-reported sedentary time explains variation in perceived health and a | 2017 Jun | To investigate (1) the amount of self-reported time spent sedentary among a large cohort of persons with rheumatoid arthritis (RA), and (2) the contribution of sedentary time to explain perceived health and activity limitation in RA beyond that of previously known correlates. This cross-sectional study used data from a postal questionnaire and the Swedish Rheumatology Quality registers (SRQ). The International Physical Activity Questionnaire was used to assess sedentary time (sitting) and moderate, vigorous and walking activity (MVPA). Sociodemographics, pain, fatigue, fear-avoidance beliefs, anxiety/depression, disease duration, MVPA and sedentary time were included in multiple regression models with perceived health (Visual Analogue Scale 0-100) and activity limitation (Stanford Health Assessment Questionnaire) as dependent variables. RESULTS: In all 3152 (59%) of 5391 persons identified as eligible from the SRQ, responded to the questionnaire. 2819 individuals with complete data on all study variables were analysed. Mean time (SD) spent sedentary was 257 (213) minutes per day. Sedentary time did not contribute significantly to explain perceived health and only minimally to explain activity limitation. Instead, variation was mainly explained by pain; for perceived health (Beta = 0.780, p < 0.001) and for activity limitation (Beta = 0.445, p < 0.001).The results indicate a non-significant role of sedentary time and a need for increased focus on pain in the management of RA. Future studies should use prospective designs and objective assessment methods to further investigate the associations between sedentary time and health outcomes in persons with RA. | |
29141665 | Matrix metalloproteinase-3 and the 7-joint ultrasound score in the assessment of disease a | 2017 Nov 15 | BACKGROUND: This study aimed to investigate the reliability and validity of serum matrix metalloproteinase-3 (MMP-3) levels and articular ultrasound (US) scores in assessing disease activity and therapeutic response in rheumatoid arthritis (RA) patients. METHODS: A total of 151 RA patients were enrolled, of whom 22 were treated with certolizumab pegol (Cimzia, CZP). The RA patients were divided into the following four subgroups according to their disease activity score in 28 joints (DAS28): stable, mild activity, moderate activity, and high activity. Forty-three healthy controls were simultaneously studied. The serum MMP-3 levels and 7-joint US (US7) scores of all subjects were determined. The patients who were treated with CZP were subsequently followed for 6Â months. RESULTS: The serum MMP-3 levels of all the RA patients were significantly higher than those of healthy controls, and those of patients with moderate and severe RA were significantly higher than those of patients with stable RA. The US7 scores of patients with severe RA were significantly higher than those of patients in other groups. Using the DAS28 as a reference standard, the corresponding cutoff value of MMP-3 was 70.5Â ng/ml. After CZP treatment, the MMP-3 levels and US7 scores were significantly decreased at week 2, and the mean changes in US7 scores at weeks 12 and 24 were significantly higher in both groups with American College of Rheumatology 50% positive response (ACR50) and ACR 70% positive response (ACR70) than in the negative groups. CONCLUSION: Serum MMP-3 and the US7 scores could both effectively reflect disease activity and therapeutic responses in patients with moderate to severe RA.

28266606 | Polymorphisms and Pharmacogenomics for the Clinical Efficacy of Methotrexate in Patients w | 2017 Mar 7 | Methotrexate (MTX) is widely used and considered a first-line disease modifying anti-rheumatic drug (DMARD) for the treatment of rheumatoid arthritis (RA). Many of the relevant genes have been investigated to estimate the association between gene polymorphisms and MTX effectiveness in RA patients, although inconsistent results have been reported. A systematic review and meta-analysis were performed to identify genetic variants associated with MTX efficacy. A total of 30 publications that included 34 genes and 125 SNPs associated with the transporters, enzymes, and metabolites of MTX or the progression of RA were included in the systematic review (SR), and 21 studies were included in 9 meta-analyses. Associations between MTX response in RA patients in MTHFR 1298A > C (rs1801131), ATIC 347C > G (rs2372536), RFC-1 80G > A (rs1051266), SLC19A1 A > G (rs2838956) and SLC19A1 G > A (rs7499) genetic polymorphisms were found, but not observed between the MTHFR 677C > T (rs1801133), TYMS 28 bp VNTR (rs34743033), MTRR 66A > G (rs1801394), and ABCB1 3435C > T (rs1045642). However, for the polymorphisms not being associated following meta-analysis could still be associated if larger cohorts were used, and studies of other polymorphisms are necessary in large cohorts and a rigorous way, which may provide more accurate results for the effect of the gene polymorphisms on the MTX response. | |
28875246 | Elevated serum 14-3-3η protein may be helpful for diagnosis of early rheumatoid arthritis | 2017 Nov | Osteoporosis (OP) is one of the signs of bone damage in rheumatoid arthritis (RA). The 14-3-3η protein is an inflammatory protein, which has been reported to be associated with rheumatoid arthritis (RA). This is to determine the serum levels of 14-3-3η protein, evaluate its diagnostic value in early RA, and clear out its significance in RA with secondary osteoporosis. Two hundred fifty-nine RA patients and 80 age and sex-matched healthy controls were included. Assays of serum 14-3-3η protein were done for all participants by enzyme-linked immunosorbent assay (ELISA). Dual-energy X-ray absorptiometry (DEXA) was used to measure bone mineral density (BMD). Serum 14-3-3η protein level was significantly high in RA (2.49/4.72), compared with controls (P < 0.0001). Positive rate of 14-3-3η protein in RA was 97.3%, which was higher than that in controls (χ (2) = 276.641, P < 0.0001). Serum 14-3-3η protein level in early RA was significantly higher than that in established RA (3.91/4.82 vs 2.01/3.29, Z = 2.624, P < 0.05). The positive rate among three groups (normal control, early RA group, established RA group) differed from each other (χ (2) = 131.396, P < 0.0001). Results of ROC curve indicated the cutoff point of 14-3-3η protein for diagnosis of early RA was 0.879 ng/ml (P < 0.0001). Linear correlation analysis found that serum 14-3-3η protein positively correlated with VAS and HAQ (P < 0.0001), negatively correlated with BMD at lumbar spine and femur in RA (P < 0.0001). Serum 14-3-3η protein among groups of bone mass normal (2.73/3.79), osteopenia (3.15/4.86), and osteoporosis (6.34/6.42) was different in early RA patients (χ (2) = 7.974, P < 0.05). Serum 14-3-3η protein levels increase significantly in patients with RA (especially in early RA). There are close relationships between serum 14-3-3η protein and clinical symptoms and osteoporosis in patients with RA. | |
29185111 | Factors influencing spinal sagittal balance, bone mineral density, and Oswestry Disability | 2018 Feb | PURPOSE: To identify the factors influencing spinal sagittal alignment, bone mineral density (BMD), and Oswestry Disability Index (ODI) outcome measures in patients with rheumatoid arthritis (RA). METHODS: We enrolled 272 RA patients to identify the factors influencing sagittal vertical axis (SVA). Out of this, 220 had evaluation of bone mineral density (BMD) and vertebral deformity (VD) on the sagittal plane; 183 completed the ODI questionnaire. We collected data regarding RA-associated clinical parameters and standing lateral X-ray images via an ODI questionnaire from April to December 2012 at a single center. Patients with a history of spinal surgery or any missing clinical data were excluded. Clinical parameters included age, sex, body mass index, RA disease duration, disease activity score 28 erythrocyte sedimentation rate (DAS28-ESR), serum anti-cyclic citrullinated peptide antibody, serum rheumatoid factor, serum matrix metalloproteinase-3, BMD and treatment type at survey, such as methotrexate (MTX), biological disease-modifying anti-rheumatic drugs, and glucocorticoids. We measured radiological parameters including pelvic incidence (PI), lumbar lordosis (LL), and SVA. We statistically identified the factors influencing SVA, BMD, VD, and ODI using multivariate regression analysis. RESULTS: Multivariate regression analysis showed that larger SVA correlated with older age, higher DAS28-ESR, MTX nonuse, and glucocorticoid use. Lower BMD was associated with female, older age, higher DAS28-ESR, and MTX nonuse. VD was associated with older age, longer disease duration, lower BMD, and glucocorticoid use. Worse ODI correlated with older age, larger PI-LL mismatch or larger SVA, higher DAS28-ESR, and glucocorticoid use. CONCLUSIONS: In managing low back pain and spinal sagittal alignment in RA patients, RA-related clinical factors and the treatment type should be taken into consideration. | |
28185415 | Relationship between clinical evaluation and ultrasound assessment of rheumatoid arthritis | 2017 Jul | AIM: To identify if the use of a systematic ultrasound (US) evaluation has relevance in the determination of disease activity in rheumatoid arthritis patients on biological disease-modifying anti-rheumatic drug treatment. METHODS: A 12 joint US assessment was performed on the same day of the routine clinical examination. Both Grey-scale (GS) and Power Doppler (PD) were graded semi-quantitatively (0-3 scale). RESULTS: Forty-one patients were included. GS or PD > 0 were found in 24% and 3% of the ankles, 21% and 17% of the wrists, 19% and 9% of the second metacarpophalangeal joints (MCP), 7% and 2% of the third MCP, 6% and 0% of the knees and 5% and 0% of the elbows, respectively; tenosynovitis of the tibialis posterior was found in 19% of the ankles. Eight of the patients with Disease Activity Score of 28 joints (DAS28) ≤ 2.6 (n = 15) had an US score of 0. Twenty-seven joints (6.7%) had US evidence of synovitis but were not considered to be swollen; 10 (2.5%) were considered to be swollen but had no US evidence of synovitis. CONCLUSIONS: Using a 12 joint US assessment, a high proportion of patients with DAS28 < 2.6 were found to have inflammatory US activity, and a significant proportion of patients had evidence of tenosynovitis of the tibialis posterior, which may be difficult to clinically detect. A regular and standardized US assessment of RA patients is therefore warranted to complement clinical evaluation and better define disease activity. | |
27659504 | Impact of non-steroidal anti-inflammatory drugs on cardiovascular risk: Is it the same in | 2017 Jul | Although large-scale population studies have shown that non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of myocardial infarction, this is not confirmed in patients with rheumatoid arthritis (RA). Herein, we review the litterature on the differential effects of NSAIDs on cardiovascular risk in osteoarthritis (OA) versus RA and discuss possible explanations for this discrepancy. To assess a potential additive effect of age in non-RA populations, we compared weighted mean age between RA patients and unselected NSAID users included in cohort and case-control studies that estimate the cardiovascular risk of NSAIDs, assuming that the main indication for NSAID usage in elderly populations is OA. Our hypothesis that advanced age in osteoarthtitis compared to RA patients confounds the effect of NSAIDs on cardiovasular risk was not confirmed. Several other hypotheses that can be proposed to explain this counterintuitive effect of NSAIDs on the cardiovascular risk of RA patients are discussed. We conclude that patients with RA have a lower cardiovascular disease risk associated with the use of NSAIDs, probably due to the nature of their disease per se, until further research indicates differently. | |
28104371 | In vitro and in vivo evaluation of anti-arthritic, antioxidant efficacy of fucoidan from U | 2017 Apr | Seaweed and their constituents have been traditionally employed for the management of various human pathologic conditions such as edema, urinary disorders and inflammatory anomalies. The current study was performed to investigate the antioxidant and anti-arthritic effects of fucoidan from Undaria pinnatifida. A noteworthy in vitro antioxidant potential at 500μg/ml in 2, 2-diphenyl-1-picrylhydrazyl scavenging assay (80% inhibition), nitrogen oxide inhibition assay (71.83%), hydroxyl scavenging assay (71.92%), iron chelating assay (73.55%) and a substantial ascorbic acid equivalent reducing power (399.35μg/mg ascorbic acid equivalent) and total antioxidant capacity (402.29μg/mg AAE) suggested fucoidan a good antioxidant agent. Down regulation of COX-2 expression in rabbit articular chondrocytes in a dose (0-100μg) and time (0-48h) dependent manner, unveiled its in vitro anti-inflammatory significance. In vivo carrageenan induced inflammatory rat model demonstrated a 68.19% inhibition of inflammation whereas an inflammation inhibition potential of 79.38% was recorded in anti-arthritic complete Freund's adjuvant-induced arthritic rat model. A substantial ameliorating effect on altered hematological and biochemical parameters in arthritic rats was also observed. Therefore, findings of the present study prospects fucoidan as a potential antioxidant that can effectively abrogate oxidative stress, edema and arthritis-mediated inflammation and mechanistic studies are recommended for observed activities. | |
29110355 | Long non-coding RNAs in rheumatoid arthritis. | 2018 Feb | Rheumatoid arthritis, a disabling autoimmune disease, is associated with altered gene expression in circulating immune cells and synovial tissues. Accumulating evidence has suggested that long non-coding RNAs (lncRNAs), which modulate gene expression through multiple mechanisms, are important molecules involved in immune and inflammatory pathways. Importantly, many studies have reported that lncRNAs can be utilized as biomarkers for disease diagnosis and prognostication. Recently, dysregulation of lncRNAs in rheumatoid arthritis and other autoimmune diseases has been revealed. Experimental studies also confirmed their crosstalk with matrix metalloproteinases, nuclear factor-κB signalling and T-cell response pertinent to autoimmunity and inflammation. Circulating lncRNAs, such as HOTAIR, differentiated patients with rheumatoid arthritis from healthy subjects. Taken together, lncRNAs are good candidates as biomarkers and therapeutic targets in rheumatoid arthritis. Further investigation on in vivo delivery of these regulatory molecules and large-cohort validation of their clinical applicability may be useful. | |
28259162 | Joint-specific assessment of swelling and power Doppler in obese rheumatoid arthritis pati | 2017 Mar 4 | BACKGROUND: Clinical swollen joint examination of the obese rheumatoid arthritis (RA) patient can be difficult. Musculoskeletal Ultrasound (MSUS) has higher sensitivity than physical examination for swollen joints (SJ). The purpose of this study was to determine the joint-specific association between power Doppler (PDUS) and clinical SJ in RA across body mass index (BMI) categories. METHODS: Cross-sectional clinical and laboratory data were collected on 43 RA patients. PDUS was performed on 9 joints (wrist, metacarpalphalangeal 2-5, proximal interphalgeal 2/3 and metatarsalphalangeal 2/5). DAS28 and clinical disease activity index (CDAI) were calculated. Patients were categorized by BMI: <25, 25-30, and >30. Demographic and clinical characteristics were compared across BMI groups with Kruskal-Wallis test and chi-square tests. Joint-level associations between PDUS and clinically SJ were evaluated with mixed effects logistic regression models. RESULTS: While demographics and clinically-determined disease activity were similar among BMI groups, PDUS scores significantly differed (p = 0.02). Using PDUS activity as the reference standard for synovitis and clinically SJ as the test, the positive predictive value of SJ was significantly lower in higher BMI groups (0.71 in BMI < 25, 0.58 in BMI 25-30 and 0.44 in BMI < 30) (p = 0.02). The logistic model demonstrated that increased BMI category resulted in decreased likelihood of PDUS positivity (OR 0.52, p = 0.03). CONCLUSIONS: This study suggests that in an obese RA patient, a clinically assessed SJ is less likely to represent true synovitis (as measured by PDUS). Disease activity in obese RA patients may be overestimated by CDAI/DAS28 calculations and clinicians when considering change in therapy. | |
27812736 | Integrative analysis for identification of shared markers from various functional cells/ti | 2017 Feb | Rheumatoid arthritis (RA) is a systemic autoimmune disease. So far, it is unclear whether there exist common RA-related genes shared in different tissues/cells. In this study, we conducted an integrative analysis on multiple datasets to identify potential shared genes that are significant in multiple tissues/cells for RA. Seven microarray gene expression datasets representing various RA-related tissues/cells were downloaded from the Gene Expression Omnibus (GEO). Statistical analyses, testing both marginal and joint effects, were conducted to identify significant genes shared in various samples. Followed-up analyses were conducted on functional annotation clustering analysis, protein-protein interaction (PPI) analysis, gene-based association analysis, and ELISA validation analysis in in-house samples. We identified 18 shared significant genes, which were mainly involved in the immune response and chemokine signaling pathway. Among the 18 genes, eight genes (PPBP, PF4, HLA-F, S100A8, RNASEH2A, P2RY6, JAG2, and PCBP1) interact with known RA genes. Two genes (HLA-F and PCBP1) are significant in gene-based association analysis (PÂ =Â 1.03E-31, PÂ =Â 1.30E-2, respectively). Additionally, PCBP1 also showed differential protein expression levels in in-house case-control plasma samples (PÂ =Â 2.60E-2). This study represented the first effort to identify shared RA markers from different functional cells or tissues. The results suggested that one of the shared genes, i.e., PCBP1, is a promising biomarker for RA. | |
28639276 | Construction of meaningful identities in the context of rheumatoid arthritis, motherhood a | 2017 Dec | AIMS AND OBJECTIVES: To derive new conceptual understanding about how women with rheumatoid arthritis manage their illness, motherhood and paid work, based on a comprehensive overview of existing knowledge, gained from qualitative studies. BACKGROUND: Rheumatoid arthritis affects several social aspects of life; however, little is known about how women with rheumatoid arthritis simultaneously manage their illness, motherhood and paid work. DESIGN: Qualitative metasynthesis. METHODS: A qualitative metasynthesis informed by Noblit and Hare's meta-ethnography was carried out, based on studies identified by a systematic search in nine databases. RESULTS: Six studies were included. Social interactions in the performance of three interdependent subidentities emerged as an overarching category, with three subcategories: subidentities associated with (1) paid work, (2) motherhood and (3) rheumatoid arthritis. Pressure in managing one of the subidentities could restrict the fulfilment of the others. The subidentities were interpreted as being flexible, situational, contextual and competing. The women strove to construct meaningful subidentities by taking into account feedback obtained in social interactions. CONCLUSIONS: The subidentities associated with paid work and motherhood are competing subidentities. Paid work is given the highest priority, followed by motherhood and illness is the least attractive subidentity. Because of the fluctuating nature of the illness, the women constantly reconstruct the three interdependent subidentities. RELEVANCE TO CLINICAL PRACTICE: When healthcare professionals meet a woman with rheumatoid arthritis, they should consider that she might not accept the subidentity as an ill person. Health professionals should not expect that women will prioritise their illness in their everyday life. This could be included in clinical conversation with the women. | |
28646516 | Tofacitinib restores the inhibition of reverse cholesterol transport induced by inflammati | 2017 Sep | BACKGROUND AND PURPOSE: Patients with active rheumatoid arthritis (RA) have increased cardiovascular mortality, paradoxically associated with reduced circulating lipid levels. The JAK inhibitor tofacitinib ameliorates systemic and joint inflammation in RA with a concomitant increase in serum lipids. We analysed the effect of tofacitinib on the lipid profile of hyperlipidaemic rabbits with chronic arthritis (CA) and on the changes in reverse cholesterol transport (RCT) during chronic inflammation. EXPERIMENTAL APPROACH: CA was induced in previously immunized rabbits, fed a high-fat diet, by administering four intra-articular injections of ovalbumin. A group of rabbits received tofacitinib (10 mg·kg(-1) ·day(-1) ) for 2 weeks. Systemic and synovial inflammation and lipid content were evaluated. For in vitro studies, THP-1-derived macrophages were exposed to high lipid concentrations and then stimulated with IFNγ in the presence or absence of tofacitinib in order to study mediators of RCT. KEY RESULTS: Tofacitinib decreased systemic and synovial inflammation and increased circulating lipid levels. Although it did not modify synovial macrophage density, it reduced the lipid content within synovial macrophages. In foam macrophages in culture, IFNγ further stimulated intracellular lipid accumulation, while the JAK/STAT inhibition provoked by tofacitinib induced lipid release by increasing the levels of cellular liver X receptor α and ATP-binding cassette transporter (ABCA1) synthesis. CONCLUSIONS AND IMPLICATIONS: Active inflammation could be associated with lipid accumulation within macrophages of CA rabbits. JAK inhibition induced lipid release through RCT activation, providing a plausible explanation for the effect of tofacitinib on the lipid profile of RA patients. | |
29102587 | Quality of Life in Ecuadorian Patients With Rheumatoid Arthritis: A Cross-sectional Study. | 2019 Sep | OBJECTIVES: To evaluate health-related quality of life (HRQoL) and associated clinical, demographic and socioeconomic factors in a cohort of Ecuadorian patients with rheumatoid arthritis (RA). PATIENTS AND METHODS: A cross-sectional descriptive study evaluating (HRQoL) with the Spanish version of the Quality of Life Rheumatoid Arthritis (QoL-RA) instrument in patients diagnosed with RA according to the criteria of the American College of Rheumatology and the European League Against Rheumatism. In addition, the following data were obtained: age, sex, marital status, socioeconomic stratum, comorbidities, disease duration, medication, rheumatoid factor positivity, disease activity using the simplified disease activity index and physical functionality measured with the modified Health Assessment Questionnaire (MHAQ). RESULTS: A total of 163 patients were assessed, the mean score of the QoL-RA scale was 6.84±1.5 points. The highest measurements were obtained in the domains of interaction (8.04±1.9) and support (8.01±2). The factors that were associated with the overall quality of life assessment were: functionality measured with MHAQ (r=-0.70; P<.001); disease duration in years (r=-0.178; P<.05); and disease activity (mean difference of 1.5; 95%CI: 1.09 to 1.91). CONCLUSION: The patients evaluated had a good to moderate HRQoL. The domains related to support and social life were those with the highest scores and the lowest scores were related to pain and nervous tension. Functionality, duration, and disease activity were statistically associated with HRQoL. | |
28494214 | The role and therapeutic targeting of IL-6 in rheumatoid arthritis. | 2017 Jun | Rheumatoid arthritis (RA) is an autoimmune chronic disease with joint and systemic inflammation and it has been found that interleukin-6 (IL-6) plays a key role in RA. Indeed, various clinical studies have proved that the first-in-class IL-6 inhibitor, tocilizumab, a humanized anti-IL-6 receptor monoclonal antibody, showed outstanding efficacy in RA. Areas covered: We review here the role of IL-6 in the inflammatory conditions and how IL-6 contributes to pathogenesis of RA, what induces IL-6 and how IL-6 expression is regulated. Furthermore, clinical studies of tocilizumab for RA are summarized, Expert commentary: We review and discuss the prospects for future applications of IL-6 targeting therapy and new therapeutic strategies targeting IL-6. Finally, we discuss relevant issues with regard to the clinical management of IL-6 blockade in RA. | |
28532573 | Global assessments of disease activity are age-dependent determinant factors of clinical r | 2017 Dec | OBJECTIVE: The aim of the study is to assess the factors associated with clinical remission of patients with rheumatoid arthritis (RA) in daily clinical practice. METHODS: This analysis was based on the data of 304 RA patients in our center between May 2014 and March 2015. The following information was included: tender, swollen, and symptomatic joint counts, patient's and physician's global assessments, functional disability, laboratory and radiographic data, and RA treatments received. RESULTS: The patients were predominantly female (77.6%), with a median age of 71 years and a median disease duration of 5.8 years. Clinical remission rate, determined using the simplified disease activity index (SDAI), was 49.7%. Patient's and physician's global assessments (/10cm) showed a higher score among patients who did not achieve SDAI remission than among those who did (median: 3.2 versus 0.3, p < 0.0001; and median: 1.8 versus 0.3, p < 0.0001, respectively). The contribution of serum C-reactive protein values (mg/dL) to SDAI was limited (median: 0.19 versus 0.06; p < 0.0001), as well as tender or swollen joint counts (median = 0 or 1). On multivariate analysis of factors not directly related to the disease activity, age was an independent risk factor for non-remission, and global assessment scores by patients and physicians showed an age-dependent increase, while counts of tender, swollen and symptomatic joints were comparable among elderly and non-elderly patients. CONCLUSION: Global assessment of disease activity was age-dependent and independent of joint counts, and it provides a critical determinant of clinical non-remission. | |
28434476 | A qualitative approach exploring the acceptability of yoga for minorities living with arth | 2017 Apr | OBJECTIVES: To examine the acceptability of yoga research tailored to recruit and retain a minority population (both English and Spanish speaking) with arthritis. Yoga research for arthritis often underrepresents minorities and acceptability for this population has not previously been investigated. DESIGN: Acceptability was evaluated using retention, adherence, journals, and semi-structured exit interviews from twelve participants with osteoarthritis or rheumatoid arthritis undergoing an 8-week yoga intervention. Journal quotes were analyzed using content analysis techniques. NVivo software was used to organize transcripts and assemble themes. Two methods of triangulation (data and investigator) were used to overcome potential bias from a single-perspective interpretation. Exit interview comments were content analyzed using a card sort method. The study was designed with a cultural infrastructure including a multicultural research team, translators, and bilingual materials and classes, to facilitate trust and acceptability for primarily Hispanic and Black/African-American adults. SETTING: Washington, D.C. metropolitan area, USA. RESULTS: On average participants attended 10 of 16 classes, with home practice 2-3days a week. All who completed were still practicing yoga three-months later. Qualitative narrative analysis identified major themes related to facilitating factors and barriers for yoga practice, self-efficacy, and support. Participant comments indicated that offering an arthritis-based yoga intervention and using a culturally congruent research design was found to be acceptable. CONCLUSIONS: As yoga research grows, there is a need to understand and promote acceptability for typically under-represented populations. This study attempts to inform the expansion of multicultural research designed to recruit and retain those from diverse backgrounds. | |
28681572 | Exploring perceptions of a rheumatoid arthritis-specific smoking cessation programme. | 2018 Mar | AIM: Smoking cessation is an important consideration in the management of rheumatoid arthritis (RA). The aim of the present study was to determine which aspects of a novel three-month smoking cessation intervention were most useful for people with RA, and to identify areas for improvement. METHOD: Thirty-eight current smokers with RA (19 intervention and 19 control) enrolled in a previous randomized controlled trial (RCT) of smoking cessation and two arthritis educators who had provided the intervention were interviewed. The data were analysed thematically using a combination of deductive and inductive approaches to identify themes. RESULTS: Intervention participants and the educators identified individualized support and advice as the two most important components of the smoking cessation intervention. The generic smoking cessation components and education about the links between smoking and RA were also identified as important. Nicotine replacement therapy was provided to all participants and was the most commonly reported facilitator of smoking cessation. People with RA who reported being ready to quit smoking had more success at smoking cessation. The educators were positive about ongoing provision of the smoking cessation intervention. CONCLUSION: The novel RA-specific smoking cessation intervention that had formed the basis of the previous RCT provided useful and varied options to assist quitting smoking in RA. Successful quitters were ready and motivated to quit smoking regardless of their randomization status, with nicotine replacement therapy an effective aid to quitting. Support offered by the educators was critical in the participants' perspective. | |
29187350 | Risk of losing remission, low disease activity or radiographic progression in case of bDMA | 2018 Apr | OBJECTIVES: To assess the risk of losing remission, low disease activity (LDA) or radiographic progression in the case of (1) discontinuing or (2) tapering doses of biological disease-modifying antirheumatic drugs (bDMARDs) compared with continuation of the initial treatment regimen in rheumatoid arthritis (RA) patients with remission or LDA. MATERIALS AND METHODS: A systematic literature analysis was carried out through May 2017 on the PubMed, Embase, Cochrane and international congress databases, selecting controlled trials comparing bDMARDs discontinuation/tapering versus continuation in RA patients with remission or LDA. The meta-analysis assessed the risk ratio (RR) and 95% CI of losing remission or LDA and the risk of radiographic progression after (1) discontinuing and (2) tapering doses of bDMARDs versus continuing the initial treatment. RESULTS: The meta-analysis comparing bDMARDs discontinuation versus continuation performed on nine trials showed an increased risk of losing remission (RR (95% CI)=1.97(1.43 to 2.73), P<0.0001) or LDA (RR (95% CI)=2.24(1.52 to 3.30), P<0.0001) and an increased risk of radiographic progression (RR (95% CI)=1.09(1.02 to 1.17), P=0.01) in case of bDMARD discontinuation. The meta-analysis comparing bDMARDs tapering versus continuation performed on 11 trials showed an increased risk of losing remission (RR (95% CI)=1.23(1.06 to 1.42), P=0.006) but no increased risk of losing LDA (RR (95% CI)=1.02 (0.85 to 1.23), P=0.81) nor any increased risk of radiographic progression (RR (95% CI)=1.09(0.94 to 1.26), P=0.26) in case of bDMARD tapering. CONCLUSION: Discontinuation of bDMARDs leads to an increased risk of losing remission or LDA and radiographic progression, while tapering doses of bDMARDs does not increase the risk of relapse (LDA) or radiographic progression, even though there is an increased risk of losing remission. |
