RATIONALE:
The administration of oral corticosteroids within the first hour in the emergency department is associated with reduced hospitalization rates in children with moderate and severe asthma, yet less than half of patients benefit from this recommendation. To ensure patients receive recommended treatment, a clear understanding of what is causing suboptimal care management is needed. The assessment of barriers and solutions to optimal care is often done without a thorough examination of the factors associated with non-adherence.
OBJECTIVE:
To evaluate whether knowledge of factors associated with delayed administration of systemic corticosteroids modifies the focus and prioritization of barriers and solutions identified by focus groups.
METHODS:
We conducted two parallel focus groups of emergency health care professionals - one group informed and the other non-informed of key factors. Both groups received a presentation on the acute asthma guidelines, the evidence supporting its recommendations, and current practice. In addition, the informed group was provided with the factors associated and not associated with delayed administration. The groups were given 20 minutes to discuss barriers and solutions, with 5 minutes each for voting for the main barriers and solutions. Group difference in the misdirection of discussion was measured as time spent discussing barriers that were shown not to be associated with systemic corticosteroids. Prioritization of barriers and solutions was based on group endorsement.
RESULTS:
The non-informed group spent more time discussing barriers not associated with delayed administration (15 vs. 2 minutes, P = 0.05). Although the non-informed group proposed more solutions, most were to overcome barriers not associated with delayed administration. Of the main barriers and solutions identified by each group, only one barrier and solution were similar between the two groups: emergency department overcrowding and administrating corticosteroids at triage.
CONCLUSION:
The awareness of objective factors of non-adherence enabled a more directed discussion on relevant barriers and solutions, affecting prioritization of each. The administration of oral corticosteroids at triage appears to be the best solution to overcome delayed administration.

We assessed the burden of obesity among rheumatoid arthritis patients and its impact on patient-reported outcomes. Patients receiving care at two Canadian University Centers were included. Height and weight were measured and selected sociodemographic and rheumatoid arthritis (RA) characteristics as well as patient-reported outcomes were obtained. Patients were classified according to WHO criteria and proposed RA cut points, and results were compared with national data. Using WHO criteria, 68 (34 %) RA patients were classified as obese (vs. ~25 % of Canadians). Using RA cut points, 112 (55 %) RA patients were classified as obese. With both classification methods, obese individuals had significantly higher mean HAQ scores and a higher odds of significant disability (HAQ ≥ 1: WHO OR 2.3; 95...

The long-term goal of this program is to unite the international rheumatology community to aid in enhancing clinical rheumatology services in an area that carries 25% of the world's disease burden but has only 2% of the world's human resources for health. This paper provides an overview of the rationale and progress to date of this collaborative effort toward the globalization of rheumatology.

No measure of self-efficacy has been validated for patients with systemic sclerosis (SSc). The objective of this study was to assess the validity and internal consistency reliability of the Self-Efficacy for Managing Chronic Disease (SEMCD) Scale in SSc. English-speaking SSc patients enrolled in the Scleroderma Patient-centered Intervention Network Cohort who completed the SEMCD Scale at their baseline assessment between March 2014 and June 2015 were included. Patients were enrolled from 21 sites in Canada, the United States and the United Kingdom. Confirmatory factor analysis (CFA) was used to evaluate the factor structure of the SEMCD Scale. Cronbach's alpha was calculated to assess internal consistency reliability. Hypotheses on the direction and magnitude of Pearson's correlations with psychological and phys...

Rainier was conducted to test the effectiveness of antacids in preventing acute mountain sickness. All 45 climbed to 3353 m, and 31 continued to the summit. Ten climbers listed acute mountain sickness as the reason for not attaining the summit. Of symptoms monitored throughout the climb, neither headache, nausea, dizziness, pounding heart, nor shortness of breath differed in severity between antacid-treated and placebo-treated groups. In both groups vital capacity decreased significantly with ascent (p less than 0.05), while peak flow (p less than 0.005) and minute ventilation (p less than 0.001) increased significantly. The 7 climbers with the most severe AMS symptom scores above 4000 m had significantly lower peak flow at sea level prior to ascent compared with the other 25 climbers who completed sea level tests (p less than 0.005). The results of this study fail to document efficacy for antacid use for the prevention of acute mountain sickness.

The LCD consisted of four daily servings of a liquid diet combined with an evening meal of a pre-packaged dinner entrée and provided approximately 925 kcal/d. Six of the 47 patients (12.8%) displayed gallstones at week 17, as determined by sonography. Five patients were asymptomatic when followed for up to 48 weeks. The sixth, however, reported severe abdominal pain 30 weeks after beginning treatment and required a cholecystectomy. Patients who developed gallstones, as compared with those who did not, had significantly higher baseline triglyceride and total cholesterol levels and had a significantly greater rate of weight loss. Results of this study indicate that an increased risk of gallstones is not limited to very-low-calorie diets and that the incidence of this complication should be assessed in persons who consume popular over-the-counter meal replacement plans.

We estimated the prevalence of anergy in RA and evaluated different methods to detect MTB exposure. This was a prospective pilot study of 61 patients with RA and 42 healthy controls. Tuberculin skin test (TST) antigen, Candida, and tetanus toxoid were injected intradermally using the Mantoux method. Subjects negative for TST returned for a second-step test. Whole-blood interferon-gamma (IFN-gamma) release to mycobacterial antigens was evaluated with the first-generation QuantiFeron test (QIFN). Cutaneous anergy in patients with RA was not significantly different than healthy controls (p = 0.154), and was not affected by disease modifying antirheumatic drugs (p = 0.270). In patients with RA, 16.4% had positive TST with 10 mm cutoff vs 11.9% of controls. Using a 5 mm cutoff, 21.3% of patients with RA were positive, and this increased to 29.5% with a second-step TST. QIFN detected MTB exposure in 18% of patients with RA and 19% of controls (p = 0.897). However, indeterminate QIFN tests were higher in RA patients (11.5%) compared to controls (2.4%), demonstrating a lower sensitivity to detect latent MTB. Cutaneous anergy may be less common than previously reported in patients with RA. patients. However, the single-step TST and 10 mm cutoff may fail to detect all cases of latent exposure in RA patients. High rates of indeterminate results in QIFN testing suggest that QIFN should not be employed as an alternative, single-screening test in patients with RA. These pilot results require confirmation in larger studies to determine the optimal screening strategy in RA.
