Abstract
INTRODUCTION The association between triamcinolone hexacetonide (TH) and gold nanoparticles (GNPs) represents a promising treatment due to the potential anti-inflammatory and antioxidant effects of these compounds. In this study, we evaluated the effects of intra-articular treatment of TH associated with GNPs in a mechanical model of osteoarthritis (OA). METHODS Fifty Wistar rats were divided into five groups: Sham; OA; OA+TH; OA+GNPs; OA+TH-GNPs. Both applications were performed 30 and 60 days after the model was induced. After 30 days of the last application, the animals were euthanized. RESULTS Only the combined treatment with TH and GNPs promoted a reduction in proinflammatory cytokines and an increase in anti-inflammatory cytokines. The OA+TH-GNPs group obtained a significant reduction in the production of oxidants and oxidative damage markers while an increase in antioxidants. Histologically, all treated groups showed results of a significant increase in cartilage thickness and chondrocyte count, the OA+TH-GNPs group had similar behavior to the group without osteoarthritis, with significantly smaller amounts of chondrocytes than the OA group. CONCLUSION The intra-articular use of TH associated with GNPs may be able to prevent the progression of the pathology and minimize joint degradation.

Treating psoriatic arthritis to target: discordance between physicians and patients' assessment, non-adherence, and restricted access to drugs precluded therapy escalation in a real-world cohort.

Abstract
The treat-to-target strategy (T2T) was associated with better outcomes in psoriatic arthritis (PsA) compared to standard care in clinical trials. This study aimed to analyze factors precluding treatment optimization in a T2T strategy conducted in a real-world cohort of PsA patients. A retrospective cross-sectional study nested in a cohort was conducted. Medical records of patients ≥ 18 years old, fulfilling CASPAR criteria and with at least one visit in the PsA clinic, were reviewed. Demographic data, current medication, and minimal disease activity (MDA) criteria were recorded. Reasons for the non-escalation of therapy in patients who were not classified as MDA were reported as absolute and relative frequencies. In the 8-month period, 131 visits (corresponding to 74 patients) were conducted. The MDA criteria were available in 113 visits (86.3%) and patients were classified as MDA in 31.0% of the visits (N = 35/113). Although in 69.0% of the visits patients were not in MDA, (N = 78/113), therapy was adjusted in only 42.3% (N = 33/78). Reasons precluding treatment escalation in non-MDA subjects were physician's impression of remission (57.7%, N = 26), non-adherence to previous prescription (17.8%, N = 8), restricted access to drugs (17.8%, N = 8), adverse events (11.1%, N = 5), poor understanding of medication instructions (6.7%, N = 3), patient's refusal to escalate therapy (4.4%, N = 2), and recent change in therapy (2.2%, N = 1). Discordance between the physician's clinical evaluation and the MDA criteria, non-adherence to prescription, and poor access to drugs were the main factors precluding escalation of therapy in a T2T strategy in a real-world PsA cohort.
