Psoriatic arthritis (PsA) is an inflammatory rheumatic disease characterized by different phenotypes in terms of joint involvement. The so-called oligoarticular pattern involves fewer than five active joints at a different time points. The evaluation of disease activity in this subset of patients is an unmet need due to the lack of specific indices able to capture modifications over time. ⋯ Musculoskeletal ultrasound could be useful in the assessment of treatment response in PsA patients with oligoarticular subset.

The novel coronavirus disease 2019 (COVID-19) is an infectious disease that presents an urgent challenge to global health and economy. ⋯ Country population median age significantly correlated with COVID-19 pandemic burden while mean ambient temperature shows a significant inverse correlation only in univariate analysis. Countries with older populations encountered a heavier burden from the COVID-19 pandemic. This information may be valuable for health systems in planning strategies for combating this global health hazard.
