The purpose was to determine local (articular) and systemic effects of intra-articular interleukin-1 in horses supplemented with a dietary PUFA supplement [STRUCTURE-Joint ()]. Sixteen (16) healthy, mature, light breed horses were randomly assigned to diets containing 0 or 120 mL ( = 8 per group) of ST-J for 30 d. On days 0 (prior to beginning supplementation) and 27, recombinant equine interleukin-1β () (75 ng) was injected into the left or right intercarpal joint to induce mild, transient synovitis.

Article Synopsis
  • A cross-sectional study in Québec and British Columbia examined the prevalence of SARS-CoV-2 in cats from households with confirmed human cases, involving swab and serum sample collection from 55 cats.
  • Of the tested cats, 9 showed positive viral RNA and 38 showed positive antibodies, with no specific risks tied to the presence of antibodies.
  • Cats with detectable viral RNA exhibited clinical signs, primarily sneezing, more frequently than those without viral RNA, highlighting the importance of monitoring feline health in relation to human COVID-19 cases.
