Methods: Data were obtained for horses admitted to a UK referral hospital between 2010 and 2024 diagnosed with peritonitis (peritoneal fluid nucleated cell count >10 × 10/L). Short- and long-term morbidity and mortality were assessed. Multivariable logistic regression was used to identify factors associated w...
Pancreatic α-cell dysfunction associated with equine insulin dysregulation. Insulin dysregulation (ID) in horses is characterised by insulin resistance and exaggerated insulin responses, yet the underlying endocrine mechanisms remain incompletely understood. In humans, α-cell dysfunction characterised by exaggerated glucagon secretion contributes to metabolic disease; however, the role of pancreatic α-cell function in equine ID has not previously been investigated. Objective: To investigate whether horses with moderate to severe ID exhibit α-cell dysfunction, characterised by fasting and postprandial hyperglucagonaemia as well as impaired postprandial glucagon supp...
Phenotypic associations between young horse assessments and orthopaedic diagnoses in insured Swedish Warmblood horses. Lameness is the most common health problem in riding horses, and insurance data have previously been used to investigate the prevalence of orthopaedic diagnoses in Swedish Warmblood (SWB) horses. Young horse performance testing is an important part of the SWB breeding programme and contributes data to the genetic evaluation. Assessed traits from these tests have been shown to be useful indicator traits of performance in show jumping and dressage, but their associations with orthopaedic health have not previously been investigated. Objective: To study the associations between assessed traits fr...
Serum osteocalcin is associated with scintigraphic abnormalities in lame and clinically sound racehorses. Musculoskeletal injury is a major welfare and economic challenge in racehorses, with stress-related bone injury contributing to training interruption and catastrophic failure. Advanced imaging modalities can detect early skeletal pathology but remain limited in routine screening environments. Circulating biomarkers of bone turnover may provide complementary indicators of skeletal remodelling but require validation against objective imaging findings. Objective: Evaluate whether osteocalcin (OC) and C-terminal telopeptide of type I collagen (CTX), or the CTX/OC ratio, are associated with scintig...
Warmed intravenous fluid administration attenuated a reduction in body temperature in anaesthetised horses.

Context-aware machine learning for lameness side and severity prediction in trotting horses: A proof-of-concept study. In clinical practice, lameness evaluation often relies on visual assessment under different examination conditions, including ground and figures, and remains subjective. Although objective symmetry indices provide quantitative measures of gait asymmetry, their interpretation across multiple conditions remains challenging because several complementary indices are required and their thresholds vary with context. Objective: To assess the ability of a context-aware machine learning approach to predict lameness side and severity at the trot using trunk-mounted IMUs. Methods: Retrospective observati...

Challenges for interpreting results of antimicrobial susceptibility testing for treating infections of foals with Rhodococcus equi. Rhodococcus equi is a facultative intracellular pathogen and a major cause of pneumonia in foals worldwide. The standard treatment for affected foals is a combination of a macrolide with rifampicin. The widespread use of this combination has led to the emergence of multidrug-resistant (MDR) strains of R. equi. Consequently, antimicrobial susceptibility testing is essential for guiding treatment of rhodococcal pneumonia. Unfortunately, clinical breakpoints for macrolides and other antimicrobials against R. equi for foals are lacking, thereby complicating clinical interpretation of in vitro resu...
Ostium-specific equine pulmonary vein myocardial sleeve gross anatomy and structural evidence of interatrial myocardial continuity with potential implications for ablation strategies. Pulmonary vein (PV) myocardial sleeves (MSs) harbour an arrhythmogenic substrate for atrial fibrillation. However, equine-specific data on MS distribution and wall thickness are limited yet essential for developing ablation strategies. In humans, posterior interatrial connections can compromise right-sided PV isolation. Objective: To study equine PV MS distribution, quantify ostial/branch diameters, antral lengths, characterise MS distal edge morphology, measure wall thickness and explore an interatrial myocardial continuity between the MSs of caudal branches draining through ostium III (PV II...
