Treatment with ertugliflozin mitigates the hyperinsulinemic response to intra-articular triamcinolone acetonide. Intra-articular (IA) corticosteroids can cause hyperinsulinemia, which can subsequently increase the risk of laminitis, particularly in horses with insulin dysregulation (ID). Sodium glucose cotransporter 2 inhibitors (SGLT2i), a drug class that is being utilised more commonly in horses with insulin dysregulation, could potentially be used to control post-IA corticosteroid hyperinsulinemia. Objective: To determine whether treatment with the SGLT2i drug ertugliflozin decreases hyperinsulinemia following intra-articular corticosteroid administration in metabolically normal horses. Methods: Prosp...
Experimental infection of horses with African horse sickness virus results in overt disseminated intravascular coagulation. African horse sickness (AHS), caused by the vector-borne African horse sickness virus (AHSV), is endemic to sub-Saharan Africa and infection results in high mortality in naïve equine populations. Clinical signs include submucosal petechiae and prolonged bleeding post venepuncture indicative of hypocoagulation. Pathological activation of haemostasis may result from tissue factor expression as a result of vascular endothelial damage or dysfunction, the proposed pathologic mechanism in AHS, potentially resulting in disseminated intravascular coagulation (DIC). Objective: To describe haemostatic ...
Risk assessment for condylar stress fracture in elite racing Thoroughbreds using standing computed tomography-based virtual mechanical testing. Condylar stress fracture of the third metacarpal bone (MC3) is a common catastrophic injury in Thoroughbred racehorses and is associated with parasagittal groove (PSG) subchondral osteolysis. Standing computed tomography (sCT) imaging enables sensitive identification of this fatigue-induced early subchondral bone injury (SBI), but there is no objective method for identifying racehorses at heightened risk of condylar stress fracture. Objective: To estimate PSG first principal strain in elite Thoroughbred racehorses that have undergone subjective risk assessment using sCT fetlock screening. Meth...

Synovial chemokine and cytokine profiles in horses with and without systemic Borrelia burgdorferi infection. Lyme arthritis, a well-documented subtype of arthritis in humans and dogs, is caused by Borrelia burgdorferi and spread primarily through ticks (Ixodes spp.). While Lyme disease in horses is known to cause a variety of clinical signs, its involvement in the development of equine arthritis is controversial. As climate change enables tick populations to expand, more horses could be exposed to B. burgdorferi; therefore, a greater understanding of how Lyme disease affects joints is critical to preserving soundness. Objective: To determine if systemic, naturally occurring Lyme disease had a discern...
Descriptive epidemiology of long-term injuries in jump racing Thoroughbreds in Great Britain. Race-related injuries in horse racing, especially those requiring extended recovery, are a welfare concern and threaten the sport's social licence.
