The objective of this study was to assess whether clinical measures of rheumatoid arthritis activity and severity were influenced by tumor necrosis factor-alpha (TNF-alpha) promoter genotype/haplotype markers. Each patient's disease activity was assessed by the disease activity score using 28 joint counts (DAS28) and functional capacity by the Health(More)
In Portugal, 13 cases of tuberculosis (TB) were reported, in the period between 1999 and 2005, in 960 patients exposed to anti-TNFalpha treatment (1.35%), 8 females and 5 males. Mean age was 46.7 +/- 13.8 years. 9 patients had rheumatoid arthritis (RA), in 639 exposed patients (1.4%), 3 had ankylosing spondylitis (AS), in 200 exposed patients (1.5%) and 1(More)
The authors present the revised version of the Portuguese Society of Rheumatology (SPR) guidelines for the treatment of Rheumatoid Arthritis (RA) with biological therapies. In these guidelines the criteria for introduction and maintenance of biological agents are discussed as well as the contraindications and procedures in the case of nonresponders.(More)
The increasing volume of data stored as XML documents makes fragmentation techniques an alternative to the performance issues in query processing. Fragmented databases are feasible only if there is a transparent way to query the distributed database. Fragments allow for intra-query parallel processing and data reduction. This paper presents our methodology(More)
The constant increase in the volume of data stored as native XML documents makes fragmentation techniques an important alternative to the performance issues in query processing over these data. Fragmented databases are feasible only if there is a transparent way to query the distributed database, without the need of knowing the fragmentation details and(More)

OBJECTIVE Our aims were to evaluate the correlation between Juvenile Arthritis Disease Activity Score 27-joint reduced count (JADAS27) with erythrocyte sedimentation rate (ESR) and JADAS27 with C-reactive protein (CRP) scores and to test the agreement of both scores on classifying each disease activity state. We also aimed at verifying the correlation of(More)
