Disease Activity and Increased Risk of Cardiovascular Death among Patients with Psoriatic Arthritis.

Objective: Recent studies indicate increased cardiovascular (CV) morbidity and mortality in patients with psoriatic arthritis (PsA), but results are inconsistent. This prompted our investigation of the mortality rate, cause of death, and incidence of acute CV events in patients from northern Sweden with PsA.

Methods: Patients with established PsA (464) were included.

The Swedish Early Psoriatic Arthritis Registry 5-year Followup: Substantial Radiographic Progression Mainly in Men with High Disease Activity and Development of Dactylitis.

Objective: To describe early radiographic findings in patients from the Swedish psoriatic arthritis (SwePsA) registry, progression of destruction, correlations with clinical disease variables, and predictors of destruction.

Methods: Hand and foot radiographs were available for 72 of 197 SwePsA patients followed for 5 years. Clinical data were collected according to the SwePsA protocol.

Range-finding risk assessment of inhalation exposure to nanodiamonds in a laboratory environment.

This study considers fundamental methods in occupational risk assessment of exposure to airborne engineered nanomaterials. We discuss characterization of particle emissions, exposure assessment, hazard assessment with in vitro studies, and risk range characterization using calculated inhaled doses and dose-response translated to humans from in vitro studies. Here, the methods were utilized to assess workers' risk range of inhalation exposure to nanodiamonds (NDs) during handling and sieving of ND powder.
