Adaptation strategies of Icelandic horses with induced transient hindlimb lameness at walk, trot and tölt. Icelandic horses are valued for their additional gaits, but assessing lameness in this breed can be challenging. Pelvic (P) vertical movement asymmetries, differences (D) in minimum (min)/maximum (max) position, are used to quantify impact (PDmin) and push-off (PDmax) hindlimb lameness during the trot, but no established parameters exist for detecting hindlimb lameness in other gaits. Objective: To evaluate temporal stride parameters and upper-body movement asymmetry after transient hindlimb lameness induction in walk, trot and tölt. Methods: In vivo experiment. Methods: Eleven Icelandic hors...
Racing and sales performance in Thoroughbred yearlings after carpal osteochondral fragment removal. While radiographically evident carpal osteochondral fragments (COF) in Thoroughbred yearlings impair sales, their impact on future racing performance has been minimally investigated. Objective: To assess the impact of COF on Thoroughbred yearling sales and racing performance, and whether these are improved by arthroscopic removal. We hypothesised that surgical removal of COF improves Thoroughbred yearling sales and racing performance. Methods: Retrospective observational. Methods: Using clinical records from years 2015-2018, 46 Thoroughbred yearlings with COF were identified and allocated to a...
Equine epiglottitis: Diagnosis, treatment and outcome. Epiglottitis is an uncommon upper airway pathology manifested endoscopically by mucosal oedema, reddening and thickening of the epiglottic mucosa. Literature on epiglottitis in horses is sparse. Objective: To describe the diagnosis, treatment and outcome of Thoroughbred and Standardbred racehorses diagnosed with epiglottitis at a single centre. A secondary objective is to demonstrate the efficacy of inhaled and topical anti-inflammatories for this condition. Methods: Retrospective case series. Methods: Medical records (2009-2023) were reviewed for racehorses treated for epiglottitis. Data coll...
Dysphagia in an equine referral hospital, 182 cases. Dysphagia describes a clinical sign of pathologies of the oral cavity, pharynx, and oesophagus that carries potentially serious consequences for horses. Given the diversity of differential diagnoses that may cause dysphagia, an understanding of the prevalence of dysphagia in hospitalised patients, the distribution of aetiologies and clinical outcomes could inform diagnosis, treatment, and prognosis. Objective: This study aims to describe the incidence, signalment, history, aetiology, treatment, and outcome of horses presenting to a referral hospital for dysphagia. Methods: Retrospective case s...
Treatment outcomes for equine osteoarthritis with mesenchymal stromal cells and hyaluronic acid. Mesenchymal stromal cells (MSCs) are widely used to treat osteoarthritis (OA).

Haemoglobin, albumin and haematocrit c...
Diagnostic performance of ultrasonography, bursography and standing magnetic resonance to detect navicular intrabursal pathology in horses with foot pain. Navicular intrabursal pathology (NIP) is a common cause of forelimb lameness in horses. An accurate diagnosis of which structure is involved is essential for therapy and prognosis.

Synovial fluid alpha-2-macroglobulin, gelsolin and lubricin distinguish between osteoarthritic and healthy equine joints. Synovial fluid (SF) is an ideal sentinel fluid for osteoarthritis (OA) diagnosis and prognostication due to its critical homeostatic role, proximity to articular tissues and immune cell composition. Untargeted proteomics enable identification of soluble markers for diagnostic and therapeutic applications while minimising bias. Objective: To use liquid chromatography-tandem mass spectrometry (LC-MS/MS) to define the SF proteome in horses with and without carpal OA. The goal was to identify differentially regulated proteins in mild-moderate carpal joint disease compared with healthy joints. Meth...

Magnetic resonance Imaging for diagnosing and managing deep digital flexor tendinopathy in equine athletes: Insights, advances and future directions. Deep digital flexor (DDF) tendinopathy is a significant cause of lameness and poor performance in equine athletes with substantial implications for their return to athletic performance. Magnetic resonance imaging (MRI) is increasingly integrated into the diagnostic workup of horses with foot pain and has revolutionised the diagnosis and management of these injuries. This review discusses the principles of MRI in the context of deep digital flexor tendon (DDFT) injury, comparing high-field and low-field systems and highlighting the clinical relevance of technical parameters, including field str...

Osteochondrosis in horses: An overview of genetic and other factors. Osteochondrosis (OC) is a frequent manifestation of developmental orthopaedic disease, and its severe clinical presentation is known as OC dissecans (OCD). OC is defined as a disruption of the endochondral ossification process in the epiphyseal cartilage, and this disease has been reported in different mammalian species, including humans, dogs, pigs, and horses. OCD is an important cause of lameness in sport horses and is a common cause of impaired orthopaedic potential, whose clinical signs may be of minimal magnitude or manifest as severe joint effusion or clinically noticeable lameness. The...
Integration of machine learning and viscoelastic testing to improve survival prediction in horses experiencing acute abdominal pain at a veterinary teaching hospital. Viscoelastic coagulation testing (VCT) identifies subclinical disruption of coagulation homeostasis and may improve prognostication, particularly for patients with severe systemic inflammation or shock. Machine learning (ML) algorithms may capture complex relationships between clinical variables better than linear regression (GLM). Objective: To evaluate the utility of ML models incorporating VCT and clinical data to predict survival outcomes in horses with acute abdominal pain. Methods: Retrospective observational cohort study. Methods: VCT (VCM Vetâ„¢) was performed on 57 horses with acute a...

Effects of pasture consumption and obesity on insulin dysregulation and adiponectin concentrations in UK native-breed ponies. Insulin dysregulation (ID) and hypoadiponectinaemia (total [adiponectin] <7.9 μg/mL) are risk factors for laminitis. They are sometimes, but not always, associated with obesity.

Intratumoural tigilanol tiglate in the multicentre treatment of equine sarcoids and cutaneous melanomas. Intralesional chemotherapeutic administration represents an important treatment option for equine cutaneous neoplasia. Tigilanol-tiglate (TT), a novel molecule extracted from Fontainea picrosperma, an Australian rainforest plant, is registered for intratumoural treatment of canine MCT, leading to rapid oncosis and tumour slough. Evidence from horses is limited but suggests that efficacy may be similar. Objective: To evaluate the response to intratumoural TT treatment in horses with sarcoids (fibroblastic/nodular) and cutaneous melanomas. Methods: Two noncontrolled prospective multicentre clini...

A comparative evaluation of seven commercial human influenza virus antigen detection kits for the diagnosis of equine influenza. Equine influenza virus (EIV) is one of the most important pathogens causing respiratory signs in equids. Rapid antigen detection (RAD) kits are useful for point-of-care testing because they are user-friendly and provide fast results.
