Sedated dental procedures increase endogenous plasma ACTH concentration in horses in the fall. To measure the effect of sedation with detomidine and butorphanol and a routine dental procedure on endogenous plasma ACTH concentrations of healthy older horses and to determine how long this effect, if any, persists to improve testing recommendations for pituitary pars intermedia dysfunction (PPID). It was hypothesized that a sedated dental procedure would not significantly affect endogenous plasma ACTH concentrations as compared to baseline in healthy adult horses. Unassigned: This prospective crossover study included 12 healthy mares of various breeds, aged 8 to 20 years, from the universi...
Commercially available objective gait evaluation systems show good to excellent reliability in horses across hard-surface types and multiple operators. To evaluate the intrasystem reliability of an AI-based smartphone application Sleip (AI-SPA), the inertial measurement unit (IMU) system Equinosis Q Lameness Locator (LL), and the IMU system Equisym (ES) across 2 different hard surfaces and to assess the interoperator reliability for the 2 IMU systems. Unassigned: 8 mixed-breed research horses, aged 4 to 12 years, with varying degrees of gait asymmetries were utilized. To assess intrasystem reliability, horses were in-hand, straight-line trotted on either epoxy-coated concrete or rubber-coated concrete. Three trials were performed for LL and E...
Use of 2.5% polyacrylamide hydrogel mitigates joint capsule stiffness and cartilage degradation in experimental equine osteoarthritis.

Novel serum biomarkers provide evidence for an involvement of the CCL3:CCL5 axis in fatal musculoskeletal injuries in Thoroughbred racehorses. Fatal musculoskeletal (MSK) injuries in Thoroughbred (TB) racehorses adversely affect equine welfare, negatively impact public acceptance of horse racing, and cause severe economic losses for the racing industry. Biomarker assays predicting the risk of MSK injuries are currently not available. Our hypothesis was that immune system and inflammatory markers are indicators of fatal MSK injuries in TB racehorses. Unassigned: Serum samples from TB racehorses with fatal (n = 44) and nonfatal injuries (63) were collected. Serum from 2- to 5-year-old TBs submitted for annual equine infectious anemia t...
Nasopharyngeal and laryngopharyngeal collapse: intra- and interrater agreement supports novel endoscopic scoring classifications in horses. The contribution of reduced airway patency from heightened inspiratory pressure or active muscular contraction to the pathophysiology of pharyngeal collapse is unknown. Existing classifications refer to the entire pharyngeal region; however, anatomical differences are evident between rostral and caudal collapse. Novel classifications and grading systems are proposed to differentiate 2 pathologies: nasopharyngeal collapse (NPC; collapse of ≥ 1 pharyngeal wall rostral to the tip of the epiglottis; grades 0 through 4), and laryngopharyngeal collapse (LPC; collapse of ≥ 1 pharyngeal wall cauda...
