    Joachim Peitz, Gerd Horneff Pediatric Rheumatology Centre, Department of General Pediatrics and Neonatology, Asklepios Clinic, Sankt Augustin, Germany Abstract: Treatment of systemic-onset juvenile idiopathic arthritis is challenging, but the availability of cytokine antagonists targeting interleukin-1 and interleukin-6 have markedly advanced the therapeutic options. In this review, we focus on the current experience with canakinumab, an interleukin-1 monoclonal human antibody for the treatment of systemic-onset juvenile idiopathic arthritis and describe its efficacy and safety. Canakinumab is an important, safe, and valid drug in the treatment of systemic-onset juvenile idiopathic arthritis. Keywords: anakinra, canakinumab, interleukin-1, interleukin-6, systemic-onset juvenile idiopathic arthriti

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods

    Tumor necrosis factor-alpha blocker in treatment of juvenile idiopathic arthritis-associated uveitis refractory to second-line agents: results of a multinational survey.

    T Objective. Uveitis occurs in l09i»l5% of patients with juvenile idiopathic arthritis (JIA). If topical treatment fails, second—Iine agents are used to control the dismse. However, some patients need the addition of tumor necrosis factor»ot (TNF»ot) antagonist (anti-TNF). We organized a cross»sectional cohort to investigate use and efficacy of anti—TNF treatment in patients with JIA-associated uveitis. Methods. The international pediatric rheumatology community was queried about the use and efficacy of anti-TNF in treatment of HA»associated uveitis using an E-mail survey. Results. Of the 33 responding centers following 884 patients with uveitis, only 15 centers, following 404 patients, were using anti—TNF for this indication. A total of 47 patients with JIA-related uveitis treated with anti-TNF because of an insufficient response to previous therapy were reported. The mean age of the patients was 12.5 years The mean duration from onset of uveitis to start of anti-TNF t;reat~ ment was 45.1 months. Three different anti-TNF agents were used: etanercept in 34 cases, infliximab in 25 cases, and adalimumab in 3 cases. In 12 of the 34 patients etanercept was inefficacious and patients were switched to inflixirnab. The final response was rated according to a composite index as 53%/ 12%/32%, and according to physician rating as 47%/ l2%/38% representing good, moderate, and poor, respectively. in the etaneicept group; and 70%/30%/0% and 68%/24%/0% in the intliximab group. All 3 patients taking adaliniumab were responders. lntliximab was statistically significantly more efficacious for the treatment of HA-associated uveitis than etanercept (chi-square p = 0.004). Conclusion. Anti—TNF seems to be an effective treatment for refractory .llA—associated uveitis. In this cohort infliximab was more efficacious than etanercepr

    The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada

    No full text
    Answering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe

    Money in Motion: Dynamic Portfolio Choice in Retirement

    No full text
    Retirees confront the difficult problem of how to manage their money in retirement so as to not outlive their funds while continuing to invest in capital markets. We posit a dynamic utility maximizer who makes both asset location and allocation decisions when managing her retirement financial wealth and annuities, and we prove that she can benefit from both the equity premium and longevity insurance in her retirement portfolio. Even without bequests, she will not fully annuitize; rather, her optimal stock allocation amounts initially to more than half of her financial wealth and declines with age. Welfare gains from this strategy can amount to 40 percent of financial wealth (depending on risk parameters and other resources). In practice, it turns out that many retirees will do almost as well by purchasing a variable annuity invested 60/40 in stocks/bonds.
