RESUMO
To develop an evidence- based guideline for the comprehensive management of osteoarthritis (OA) as a collabora-tion between the American College of Rheumatology (ACR) and the Arthritis Foundation, updating the 2012 ACR recommenda-tions for the management of hand, hip, and knee OA.Methods. We identiîed clinically relevant population, intervention, comparator, outcomes questions and critical outcomes in OA. A Literature Review Team performed a systematic literature review to summarize evidence supporting the beneîts and harms of available educational, behavioral, psychosocial, physical, mind- body, and pharmacologic therapies for OA. Grading of Recommen-dations Assessment, Development and Evaluation methodology was used to rate the quality of the evidence. A Voting Panel, includ-ing rheumatologists, an internist, physical and occupational therapists, and patients, achieved consensus on the recommendations.Results. Based on the available evidence, either strong or conditional recommendations were made for or against the ap-proaches evaluated. Strong recommendations were made for exercise, weight loss in patients with knee and/or hip OA who are overweight or obese, self- efîcacy and self- management programs, tai chi, cane use, hand orthoses for îrst carpometacarpal (CMC) joint OA, tibiofemoral bracing for tibiofemoral knee OA, topical nonsteroidal antiinîammatory drugs (NSAIDs) for knee OA, oral NSAIDs, and intraarticular glucocorticoid injections for knee OA. Conditional recommendations were made for balance exer-cises, yoga, cognitive behavioral therapy, kinesiotaping for îrst CMC OA, orthoses for hand joints other than the îrst CMC joint, patellofemoral bracing for patellofemoral knee OA, acupuncture, thermal modalities, radiofrequency ablation for knee OA, topical NSAIDs, intraarticular steroid injections and chondroitin sulfate for hand OA, topical capsaicin for knee OA, acetaminophen, du-loxetine, and tramadol.Conclusion. This guideline provides direction for clinicians and patients making treatment decisions for the management of OA. Clinicians and patients should engage in shared decision- making that accounts for patients' values, preferences, and comor-bidities. These recommendations should not be used to limit or deny access to therapies

Background context: Lumbar spinal stenosis (LSS) leads to diminished blood flow to the spinal nerves causing neurogenic claudication and impaired walking ability. Animal studies have demonstrated increased blood flow to the spinal nerves and spinal cord with superficial para-spinal electrical stimulation of the skin. Purpose: The aim of this study was to assess the effectiveness of active para-spinal transcutaneous electrical nerve stimulation (TENS) compared to de-tuned TENS applied while walking, on improving walking ability in LSS. Study design: This was a two-arm double-blinded (participant and assessor) randomized controlled trial. Patient sample: We recruited 104 participants 50 years of age or older with neurogenic claudication, imaging confirmed LSS and limited walking ability. Outcome measures: The primary measure was walking distance measured by the self-paced walking test (SPWT) and the primary outcome was the difference in proportions among participants in both groups who achieved at least a 30% improvement in walking distance from baseline using relative risk with 95% confidence intervals. Methods: The active TENS group (n = 49) received para-spinal TENS from L3-S1 at a frequency of 65-100 Hz modulated over 3-s intervals with a pulse width of 100-200 usec, and turned on 2 min before the start and maintained during the SPWT. The de-tuned TENS group (n = 51) received similarly applied TENS for 30 s followed by ramping down to zero stimulus and turned off before the start and during the SPWT.Study funded by The Arthritis Society ($365,000 CAN) and salary support for Carlo Ammendolia funded by the Canadian Chiropractic Research Foundation ($500,000 CAN over 5 years). Results: From August 2014 to January 2016 a total of 640 potential participants were screened for eligibility; 106 were eligible and 104 were randomly allocated to active TENS or de-tuned TENS. Both groups showed significant improvement in walking distance but there was no significant difference between groups. The mean difference between active and de-tuned TENS groups was 46.9 m; 95% CI (- 118.4 to 212.1); P = 0.57. A total of 71% (35/49) of active TENS and 74% (38/51) of de-tuned TENS participants achieved at least 30% improvement in walking distance; relative risk (RR), 0.96; 95% CI, (0.7 to 1.2) P = 0.77. Conclusions: Active TENS applied while walking is no better than de-tuned TENS for improving walking ability in patients with degenerative LSS and therefore should not be a recommended treatment in clinical practice. Registration: ClinicalTrials.gov ID: NCT02592642. Registration October 30, 2015.

BACKGROUND CONTEXT: Lumbar spinal stenosis (LSS) can impair blood flow to the spinal nerves giving rise to neurogenic claudication and limited walking ability. Reducing lumbar lordosis can increases the volume of the spinal canal and reduce neuroischemia. We developed a prototype LSS belt aimed at reducing lumbar lordosis while walking. PURPOSE: The aim of this study was to assess the short-term effectiveness of a prototype LSS belt compared to a lumbar support in improving walking ability in patients with degenerative LSS. STUDY DESIGN: This was a two-arm, double-blinded (participant and assessor) randomized controlled trial. PATIENT SAMPLE: We recruited 104 participants aged 50 years or older with neurogenic claudication, imaging confirmed degenerative LSS, and limited walking ability. OUTCOME MEASURES: The primary measure was walking distance measured by the self-paced walking test (SPWT) and the primary outcome was the difference in proportions among participants in both groups who achieved at least a 30% improvement in walking distance from baseline using relative risk with 95% confidence intervals. METHODS: Within 1 week of a baseline SPWT, participants randomized to the prototype LSS belt group (n=52) and those randomized to the lumbar support group (n=52) performed a SPWT that was conducted by a blinded assessor. The Arthritis Society funded this study ($365,000 CAN) with salary support for principal investigator funded by the Canadian Chiropractic Research Foundation ($500,000 CAN for 5 years). RESULTS: Both groups showed significant improvement in walking distance, but there was no significant difference between groups. The mean group difference in walking distance was -74 m (95% CI: -282.8 to 134.8, p=.49). In total, 62% of participants wearing the prototype LSS belt and 82% of participants wearing the lumbar support achieved at least 30% improvement in walking distance (relative risk, 0.7; 95% CI: 0.5-1.3, p=.43). CONCLUSIONS: A prototype LSS belt demonstrated significant improvement in walking ability in degenerative LSS but was no better than a lumbar support.

Integrating care for people with complex needs is challenging. Indeed, evidence of solutions is mixed, and therefore, well-designed, shared evaluation approaches are needed to create cumulative learning. The Toronto-based Building Bridges to Integrate Care (BRIDGES) collaborative provided resources to refine and test nine new models linking primary, hospital and community care. It used mixed methods, a cross-project meta-evaluation and shared outcome measures. Given the range of skills required to develop effective interventions, a novel incubator was used to test and spread opportunities for system integration that included operational expertise and support for evaluation and process improvement.

OBJECTIVES: The perspectives, needs and preferences of individuals with complex health and social needs can be overlooked in the design of healthcare interventions. This study was designed to provide new insights on patient perspectives drawing from the qualitative evaluation of 5 complex healthcare interventions. SETTING: Patients and their caregivers were recruited from 5 interventions based in primary, hospital and community care in Ontario, Canada. PARTICIPANTS: We included 62 interviews from 44 patients and 18 non-clinical caregivers. INTERVENTION: Our team analysed the transcripts from 5 distinct projects. This approach to qualitative meta-evaluation identifies common issues described by a diverse group of patients, therefore providing potential insights into systems issues. OUTCOME MEASURES: This study is a secondary analysis of qualitative data; therefore, no outcome measures were identified. RESULTS: We identified 5 broad themes that capture the patients' experience and highlight issues that might not be adequately addressed in complex interventions. In our study, we found that: (1) the emergency department is the unavoidable point of care; (2) patients and caregivers are part of complex and variable family systems; (3) non-medical issues mediate patients' experiences of health and healthcare delivery; (4) the unanticipated consequences of complex healthcare interventions are often the most valuable; and (5) patient experiences are shaped by the healthcare discourses on medically complex patients. CONCLUSIONS: Our findings suggest that key assumptions about patients that inform intervention design need to be made explicit in order to build capacity to better understand and support patients with multiple chronic diseases. Across many health systems internationally, multiple models are being implemented simultaneously that may have shared features and target similar patients, and a qualitative meta-evaluation approach, thus offers an opportunity for cumulative learning at a system level in addition to informing intervention design and modification.

OBJECTIVE: The purpose of this study was to determine whether prevalent self-reported back pain predicts future osteoarthritis-related pain and disability in individuals with hip and knee osteoarthritis (OA). METHODS: We studied a population-based cohort of Ontario residents who were 55 years or older and reported symptomatic hip/knee OA at baseline (between 1996 and 1998). The sample was followed-up between 2000 and 2001. We used multivariable linear regression to model the association between baseline back pain and pain and disability (Western Ontario and McMaster Universities Osteoarthritis Index scores) at follow-up while controlling for confounders. RESULTS: Of the 983 participants, 58% of the cohort reported low back pain at baseline. Baseline low back pain predicted higher hip and/or knee OA-related pain and disability at follow-up (beta = 2.49; 95% confidence interval [CI], 0.4-4.6; P = .023). However, this association varied with the location of OA. After controlling for confounders, the association was strong for individuals with hip OA (beta = 11.41; 95% CI, 5.1-17.7; P = .001). However, low back pain was not associated with pain and disability in individuals with knee OA (beta = 0; 95% CI -3.39 to 3.39; P = .998). CONCLUSIONS: In a cohort of individuals with OA of the hip or knee, we found that low back pain predicted subsequent OA-related pain and disability in those with hip disease, but not knee disease. Our study provides valuable prognostic information to clinicians involved in the management of patients with OA of the hip and knee.

BACKGROUND: Studies of total joint arthroplasty (TJA) have not evaluated the costs and outcomes in the context of expected arthritis worsening. OBJECTIVES: Using a cost-consequence approach, to examine changes in direct health care costs and arthritis severity after TJA for hip/knee arthritis compared with contemporaneous changes in matched controls. RESEARCH DESIGN: Case control study nested in a population-based prospective cohort. SUBJECTS: In a population cohort with disabling hip/knee osteoarthritis followed from 1996 to 2003, primary TJA recipients were matched with cohort nonrecipients on age, sex, region of residence, comorbidity, and inflammatory arthritis diagnosis. MEASURES: Pre- and postoperative total and arthritis-attributable direct health care costs, arthritis severity, and general health status were compared for cases and matched controls. RESULTS: Of 2109 participants with no prebaseline TJA, 185 cases received a single elective TJA during the follow-up period; of these, 183 cases and controls were successfully matched. Mean age was 71 years, 77.6% were female, 35.5% had > or =2 comorbidities, and 81.5% had > or =2 joints affected. At baseline, controls had less pain and disability and lower total and arthritis-attributable health care costs than cases. After surgery, although overall health care utilization was unchanged, cases experienced significant decreases in arthritis-attributable costs (mean decrease $278 including prescription drugs) and pain and disability (P < 0.0001 for all). Over the same time period, controls experienced a significant increase in total health care costs (mean increase $1978 including prescription drugs, P = 0.04) and no change or worsening of their arthritis status. CONCLUSION: Compared with matched controls, arthroplasty is associated with significant reductions in pain, disability, and arthritis-attributable direct costs.

BACKGROUND: Vitamin K has been widely promoted as a supplement for decreasing bone loss in postmenopausal women, but the long-term benefits and potential harms are unknown. This study was conducted to determine whether daily high-dose vitamin K1 supplementation safely reduces bone loss, bone turnover, and fractures. METHODS AND FINDINGS: This single-center study was designed as a 2-y randomized, placebo-controlled, double-blind trial, extended for earlier participants for up to an additional 2 y because of interest in long-term safety and fractures. A total of 440 postmenopausal women with osteopenia were randomized to either 5 mg of vitamin K1 or placebo daily. Primary outcomes were changes in BMD at the lumbar spine and total hip at 2 y. Secondary outcomes included changes in BMD at other sites and other time points, bone turnover markers, height, fractures, adverse effects, and health-related quality of life. This study has a power of 90% to detect 3% differences in BMD between the two groups. The women in this study were vitamin D replete, with a mean serum 25-hydroxyvitamin D level of 77 nmol/l at baseline. Over 2 y, BMD decreased by -1.28% and -1.22% (p = 0.84) (difference of -0.06%; 95% confidence interval [CI] -0.67% to 0.54%) at the lumbar spine and -0.69% and -0.88% (p = 0.51) (difference of 0.19%; 95% CI -0.37% to 0.75%) at the total hip in the vitamin K and placebo groups, respectively. There were no significant differences in changes in BMD at any site between the two groups over the 2- to 4-y period. Daily vitamin K1 supplementation increased serum vitamin K1 levels by 10-fold, and decreased the percentage of undercarboxylated osteocalcin and total osteocalcin levels (bone formation marker). However, C-telopeptide levels (bone resorption marker) were not significantly different between the two groups. Fewer women in the vitamin K group had clinical fractures (nine versus 20, p = 0.04) and fewer had cancers (three versus 12, p = 0.02). Vitamin K supplements were well-tolerated over the 4-y period. There were no significant differences in adverse effects or health-related quality of life between the two groups. The study was not powered to examine fractures or cancers, and their numbers were small. CONCLUSIONS: Daily 5 mg of vitamin K1 supplementation for 2 to 4 y does not protect against age-related decline in BMD, but may protect against fractures and cancers in postmenopausal women with osteopenia. More studies are needed to further examine the effect of vitamin K on fractures and cancers. TRIAL REGISTRATION: ClinicalTrials.gov (#NCT00150969) and Current Controlled Trials (#ISRCTN61708241).

OBJECTIVE: Factors that influence calcium intake among women with low bone mass have not been clearly identified. The objective of this study was to evaluate confidence, attitudes and beliefs regarding calcium intake and to identify determinants of adherence to calcium recommendations among women with low bone mineral density (BMD). METHODS: Participants were 104 women with low BMD attending an initial visit to an osteoporosis program. Prior to participation in a one-on-one standardized nutrition counseling session with a dietitian, daily calcium intake was assessed using four-day food records and use of calcium supplements was reported. Calcium related knowledge and beliefs were assessed by questionnaire. Barriers and facilitators to obtaining adequate calcium intake were also reported. Six months following baseline, food records and study questionnaire were repeated. Adherence was defined as meeting > or =85% of recommended calcium intake. Logistic regression was used to examine baseline predictors of adherence to calcium recommendations at follow-up. RESULTS: Mean dietary calcium intake was 952 +/- 384 mg/day at follow-up and 91.3% were using calcium supplements. Combining dietary and supplemental calcium, approximately 77% of women were adherent to calcium recommendations at follow-up. Uncertainty regarding calcium food sources and supplements, concerns related to weight gain and the fat content of some calcium-rich foods were the most frequently reported barriers to obtaining adequate calcium intake. The only significant independent predictor of calcium adherence at follow-up was use of a calcium supplement (adjusted OR = 5.970, p = 0.012). CONCLUSIONS: Due to the nutrient synergy of foods, dietary sources of calcium should continue to be promoted in nutritional counseling efforts as the optimal method of obtaining adequate calcium. Nutrition education should emphasize strategies to decrease side effects associated with calcium-rich foods and alleviate concerns regarding the cholesterol and fat content of some calcium-rich foods. In addition to strategies to increase consumption of dietary sources of calcium, supplementation should be considered as an acceptable method of increasing calcium intake among women with low BMD.

OBJECTIVE: The purpose of this study was to examine the association between dietary intake of phytoestrogens estimated by a food frequency questionnaire (FFQ) with urinary metabolites. METHODS: Participants were 26 premenopausal, Caucasian women aged 25 to 42 years. Dietary intake of isoflavones (genistein and daidzein) and lignans (secoisolariciresinol and matairesinol) were estimated by a 53-item interviewer-administered FFQ on two occasions, reflecting 'habitual' (previous 2 months) and 'recent' (previous 2 days) dietary intake. Isoflavone (genistein, daidzein) and lignan (enterolactone, enterodiol and secoisolariciresinol) concentrations were measured in 24-hour urine samples by gas chromatography-mass spectrometry. Correlations between FFQ (habitual and recent, separately) and urinary metabolite values were assessed using Spearman correlation coefficients. RESULTS: Mean habitual isoflavone and lignan intakes were 13.7 mg/day and 13.8 mg/day, respectively. Mean urinary concentrations of isoflavones and lignans were 17.4 micromol/day and 20.6 micromol/day, respectively. Recent and habitual isoflavone intakes were correlated with urinary excretion of metabolites (r = 0.64, p < 0.001 and r = 0.54, p = 0.004, respectively). Urinary excretion of lignans was also modestly correlated with recent and habitual lignan intakes (r = 0.46, p = 0.02 and r = 0.40, p = 0.05, respectively). CONCLUSIONS: Our results support the use of this FFQ as a measure of dietary isoflavone and lignan intake in epidemiological studies.

OBJECTIVE: To estimate the prevalence of self-reported osteoporotic fractures and use of bone-sparing agents, and to examine if region of residence is associated with fracture or treatment prevalence. METHODS: A census of persons aged > or = 55 years residing in 2 regions of Ontario, Canada (East York, a region within Toronto, and Oxford County), was completed between 1995 and 1998. Region was coded by record linkage of residential postal codes to 1996 Canadian Census data into 4 groups: East York (urban core), and Oxford County subdivided into: urban core, small urban, and rural. Respondents were excluded if they resided outside the regions of interest or were missing fracture data (5%). RESULTS: A total of 26,839 persons (15,541 women) were studied. Nearly 3 times as many women as men reported having had an osteoporotic fracture (14% vs 5%), with 31% and 8%, respectively, taking bone-sparing agents. Controlling for age, a diagnosis of osteoporosis, number of osteoporotic fractures, and height loss, women residing in East York were more likely (OR 1.2, 95% CI 1.0-1.4) to be taking a bone-sparing agent other than estrogen, but less likely to be taking estrogen (OR 0.8, 95% CI 0.7-0.9) compared to those living in rural areas. No regional differences were observed in fracture prevalence, treatment among those with an osteoporotic fracture, or use of a bone-sparing agent among men. CONCLUSION: Further research into regional differences in osteoporosis screening, treatment, and fractures is warranted. This should examine the appropriateness of possible differences, and separate physician practice patterns from patient characteristics, such as willingness to begin treatment with bone-sparing agents.

OBJECTIVE: The Osteoporosis Health Belief Scale (OHBS) is a 42-item scale designed to measure general health motivation, perceived susceptibility to and seriousness of osteoporosis, and beliefs about calcium intake and exercise in preventing and treating osteoporosis. The purpose of this study was to examine the psychometric properties of the OHBS by telephone administration among older women. STUDY DESIGN AND SETTING: A convenience sample of 425 women aged 61-93 years participating in a longitudinal arthritis study was recruited by telephone. Item clarity was evaluated and 22 additional items (6 reworded, 16 from other questionnaires) were considered to supplement or replace existing scale items. Multitrait scaling techniques and exploratory factor analysis were used to test scale structure. Construct validity was tested based on theoretical hypothesis between OHBS subscale scores and participant characteristics. RESULTS: A few modifications to the OHBS scale were suggested, reducing the scale by five items (two redundant, three did not load), rewording one item and moving on item to a different subscale. The modified 37-item OHBS had a seven-factor uncorrelated solution explaining 48% of the model variance with internal consistency ranging from 0.73 to 0.88. CONCLUSION: Relatively minor changes to the OHBS results in reduced redundancy and improved internal structure of the scale for telephone administration among women over 60 years of age. Further examination is recommended to confirm these findings.

OBJECTIVE: To determine what, if any, barriers exist that prevent rheumatologists from providing adequate rheumatology care. METHODS: All 158 identified rheumatologists in Ontario were sent a self-administered questionnaire and followed up by telephone. RESULTS: The response rate was 83%. All but 6 rheumatologists reported at least one barrier to the provision of service. The 3 most commonly reported barriers were the cost of drugs for patients (83%), billing policies and regulations for consultation and followup visits (72%), and long waiting times for patients (61%). Rheumatologists reporting the latter had significantly longer waiting times (12 vs 4 wks) for new non-urgent patients, although there was no difference for new patients with inflammatory arthritis. Nearly three-quarters of respondents had changed the patterns of their practice over the last 3 years, with significant increases in the amount of independent medical services (e.g., third party billing) and pharmaceutical company work. The majority (89%) of responding rheumatologists reported having at least some difficulty in making ends meet from rheumatology practice alone and 28% found it was not possible. CONCLUSION: These results indicate that the majority of rheumatologists face significant barriers to providing adequate care. Given the recruitment and service provision concerns in Canada, these barriers to service need to be addressed to ensure adequate provision of care.

Maximizing attainment of optimal peak bone mineral density (BMD) is a potential osteoporosis prevention strategy. The main objective of this study was to identify correlates of forearm BMD in young adult women. Population-based data derived from standardized questionnaires administered to healthy women aged 19-35 years in Nord-Trøndelag, Norway (n = 963), were collected in 1995-1997. Forearm BMD was assessed by single x-ray absorptiometry. Multiple linear and logistic regression analyses were used to determine correlates of BMD (g/cm(2)) and lowest quintile of BMD, respectively, at the ultradistal and distal sites. The mean age and weight of the cohort were 29.7 years (standard deviation 4.7) and 68.6 kg (standard deviation 12.5), respectively. Age and weight were positively associated with BMD at both forearm sites. When data were controlled for age and weight, later age at menarche and lack of milk consumption were associated with lower BMD values. In both linear models and logistic models, none of the factors vitamin D intake, physical activity, smoking, alcohol consumption, amenorrhea, oral contraceptive use, number of pregnancies, history of breastfeeding, and family history of osteoporosis were found to be significantly associated with BMD. Prior studies have suggested that calcium supplementation in children is useful for optimizing peak BMD. Further studies exploring the relation between lifestyle factors and BMD are warranted to search for ways to maximize attainment of peak BMD.
