Objective To develop new composite disease activity indices for psoriatic arthritis (PsA).
Methods Data from routine clinic visits at multiple centres were collected in a systematic manner. …

Objective. During OMERACT 8, delegates selected patient global assessment (PGA) of
disease as a domain to be evaluated in randomized controlled trials in psoriatic arthritis (PsA). …

Objective. To estimate the prevalence of, and identify factors associated with, hand and
wrist US alterations in a large cohort of SLE patients. Methods. One hundred and eight …

Objective. To identify the clinical features that can help to distinguish between psoriatic
arthritis (PsA) and fibromyalgia (FM). Methods. Our cross-sectional study was carried out in 10 …

Objective: To compare drug survival of different anti-TNF drugs (inliximab, INF, etanercept,
ETA, and adalimumab, ADA) in rheumatoid arthritis (RA) and spondyloarthritis (SpA) by …

This paper concerns minimization and maximization of the first eigenvalue in problems
involving the $ p $-Laplacian, under homogeneous Dirichlet boundary conditions. Physically, in …

Objectives. HLA-B*27:05 is associated with AS whereas HLA-B*27:09 is not associated. We
hypothesized that different interactions with KIR immune receptors could contribute to the …

Objective. TNF-α antagonists, infliximab (INF), etanercept (ETA) and adalimumab (ADA), have
been demonstrated to be effective in controlling symptoms in SpAs. The aim of this study …

This paper concerns an optimization problem related to the Poisson equation for the p− Laplace
operator, subject to homogeneous Dirichlet boundary conditions. Physically the Poisson …

The paper investigates the existence, asymptotic boundary behavior and uniqueness of
convex solutions to the Monge-Ampère equation that take infinite values on the boundary of …
