Compound splitting is an important problem in many NLP applications which must be solved in order to address issues of data sparsity. Previous work has shown that linguistic approaches for German compound splitting produce a correct splitting more often, but corpus-driven approaches work best for phrase-based statistical machine translation from German to(More)
OBJECTIVE Anti-tumor necrosis factor alpha agents are among the most effective therapies for rheumatoid arthritis (RA). However, their optimal use is yet to be determined. This 12-month double-blind study attempted remission induction using standard therapy with or without infliximab in patients with early, poor-prognosis RA. The primary end point was(More)
OBJECTIVE Anti-cyclic citrullinated peptide (anti-CCP) antibodies have been identified as highly specific for rheumatoid arthritis (RA). Studies suggest an association with radiographic outcome. The aims of this study were to assess the diagnostic and prognostic utility of the second-generation anti-CCP(2) test in a large cohort of early RA patients(More)
OBJECTIVE To examine matrix metalloproteinase 9 (MMP-9) in the synovial fluid (SF) and synovial membrane (SM) in relation to vascular endothelial cell (EC) apoptosis, vascular endothelial growth factor (VEGF), and SM vascular pattern. METHODS Thirty-four patients underwent needle arthroscopy of the knee joint; 12 had early rheumatoid arthritis (RA), 12(More)
OBJECTIVE To investigate the response to biologic drugs in psoriatic arthritis and to quantify non-response and outcome from switching agents. METHODS 60 patients (33 men and 27 women, mean age 46 years, median disease duration 16 years) prescribed biologic drugs for psoriatic arthritis between 2001 and 2006 were studied. Response was evaluated using(More)
OBJECTIVES HLA-B27 positivity strongly influences Ankylosing spondylitis (AS) disease susceptibility and phenotype. The aim of this study was to analyse an AS cohort with respect to quality of life (ASQoL), extra-articular disease, markers of disease activity (BASDAI), functional capacity (BASFI), biologic requirement, and the influence of HLA-B27 on these(More)
OBJECTIVE To evaluate the efficacy of infliximab in HLA-B27-positive patients with magnetic resonance imaging (MRI)-determined early sacroiliitis, using both clinical and MRI assessments. METHODS Forty patients with recent-onset inflammatory back pain, as assessed by the Calin criteria, HLA-B27 positivity, clinical disease activity as measured by the Bath(More)
OBJECTIVE To examine angiogenic growth factors in patients with early, untreated inflammatory arthritides and controls. METHODS Synovial membrane (SM) infiltrate and Ang1, Ang2, and vascular endothelial growth factor (VEGF) mRNA and protein expression were examined using immunohistochemistry and in situ hybridization. Synovial fluid (SF) VEGF,(More)
OBJECTIVE To determine in vivo the extent of damage to, and changes in turnover of, articular cartilage type II collagen (CII) and the proteoglycan aggrecan following the onset of inflammatory arthritis in humans, and to examine the hypothesis that there are direct relationships between cartilage biomarkers of damage/turnover and clinical, histologic, and(More)
