BACKGROUND: Methylprednisolone (MP) acetate is a commonly used corticosteroid for suppression of inflammation in synovial structures in horses. Its use is often regulated in equine sports by plasma MP concentrations. OBJECTIVES: To describe variability of MP plasma concentrations after MP acetate injection in different synovial structures and with co-administration with hyaluronic acid (HA). STUDY DESIGN: Field study in actively racing horses in three disciplines (Thoroughbred, Standardbred and Quarter Horse)...

BACKGROUND: Previous studies suggest that ocular disease is common amongst aged horses but owners may fail to identify or underestimate their clinical relevance. OBJECTIVES: To document the prevalence of owner-reported ocular disease in horses aged ≥15 years. In a subset of these horses, to document ophthalmic findings from veterinary examination and compare with owner-reported ocular disease, and to determine risk factors for veterinary ophthalmic findings. STUDY DESIGN: Cross sectional study...

BACKGROUND: The use of commercial chromogenic agar plates for the rapid, easy and correct identification of equine endometritis-causing bacteria has been proposed. Preliminary tests in our lab revealed undescribed limitations. Therefore we tested the ability of the Brilliance UTI agar, a commercially available chromogenic agar, to accurately identify bacteria causing equine endometritis. Objectives To (1) investigate whether bacteria present in the equine uterus are able to grow on this chromogenic agar plate, (2) determine whether these bacteria belong to the genera for which these agar plates were originally designed and (3) consider whether these bacterial genera can be correctly identified, based only on the colour appearance...

There are currently no reports describing the use of this drug in horses. OBJECTIVES: To describe the pharmacokinetics and effects on cortisol and eicosanoid concentrations, following administration of flumethasone to exercised horses. STUDY DESIGN: Parallel design.

BACKGROUND: Studies have shown proximal diffusion of injected drugs in perineural blocks; such diffusion may affect specificity of the nerve block. OBJECTIVES: To investigate the effect of a compression bandage applied to the pastern region on proximal diffusion of contrast medium injected over the palmar digital nerves. STUDY DESIGN: Experimental study, randomised cross-over design. METHODS: Radiodense contrast medium was injected over the lateral and medial palmar digital nerves of the left front limb of nine mature horses...

BACKGROUND: Some sagittal plane fractures of the equine third carpal bone are difficult to detect with conventional radiographic projections. OBJECTIVES: To describe a novel radiographic projection for the detection of sagittal plane slab fractures of the equine third carpal bone. STUDY DESIGN: Retrospective study of radiological records. METHODS: From a first opinion Thoroughbred racehorse caseload, cases were included for analysis if sagittal fracture of the third carpal bone was evident on a dorsoproximal lateral-palmarodistal medial oblique (DPrL-PDiMO) projection of the distal row of carpal bones and not visible on the standard dorsoproximal-dorsodistal oblique (DPr-DDiO) projection...

BACKGROUND: There is little knowledge of the prescription of Non-Steroidal Anti-inflammatory Drugs (NSAIDs) and whether their prescription varies between countries. OBJECTIVE: To describe prescription practices of NSAIDs in equids in the United Kingdom (UK), United States of America (USA) and Canada. STUDY DESIGN: Descriptive observational study. METHODS: Free-text electronic medical records from 141,543 equids from 10 equine practices in the UK and 255,777 equids from 7 equine practices with 20 branches from the USA and 2 practices with 7 branches from Canada were evaluated...

BACKGROUND: Electrical impedance tomography (EIT) is a method to measure regional impedance changes within the thorax. The total tidal impedance variation has been used to measure changes in tidal volumes in pigs, dogs and humans. OBJECTIVES: To assess the ability of EIT to quantify changes in tidal volume in anaesthetised mechanically ventilated horses. STUDY DESIGN: In vivo experimental study. METHODS: Six horses (mean ± s...

BACKGROUND: Advanced mare age is associated with declining fertility and an increased risk of early pregnancy loss. Compromised oocyte quality is probably the primary reason for reduced fertility, but the defects predisposing to embryonic death are unknown. In women, advanced age predisposes to chromosome segregation errors during meiosis, which lead to embryonic aneuploidy and a heightened risk of miscarriage. OBJECTIVES: To evaluate the effect of advanced mare age on chromosome alignment and meiotic spindle morphology in in vitro-matured (IVM) oocytes...

BACKGROUND: We hypothesised that grade/appearance for upper respiratory tract (URT) disorders identified at the first overground endoscopy (OGE) examination would vary at subsequent examinations. OBJECTIVES: To compare OGE examinations from horses evaluated on at least 2 occasions under similar exercise conditions without treatment intervention. STUDY DESIGN: Retrospective cohort. METHODS: Pre-exercise and exercising OGE recordings from Thoroughbred horses undergoing multiple examinations under similar exercise conditions were reviewed, with the first 2 recordings for each horse statistically evaluated...

BACKGROUND: Unilateral ventriculocordectomy (VeC) is frequently performed, yet objective studies in horses with naturally occurring recurrent laryngeal neuropathy (RLN) are few. OBJECTIVES: To evaluate respiratory noise and exercising over-ground endoscopy in horses with grade B and C laryngeal function, before and after unilateral laser VeC. STUDY DESIGN: Prospective study in clinically affected client-owned horses. METHODS: Exercising endoscopy was performed and concurrent respiratory noise was recorded...

BACKGROUND: Bone marrow-derived mesenchymal stem cells (BM-MSCs) are frequently used in the treatment of musculoskeletal injuries. Fully characterised cells that are readily available for use is optimum. Allogenic BM-MSCs can satisfy the need for rapid treatment, however, their safety has been questioned. OBJECTIVES: Objectives were to characterise BM-MSCs from an adult donor horse, in vitro, and to identify and describe adverse reactions that occurred following their injection into other horses...

BACKGROUND: Endoscopic tip placement in the pharynx and water flushing interval (FI) may affect exercising upper respiratory tract (URT) endoscopic results. OBJECTIVES: To determine associations between the endoscopic tip position in the pharynx and automated FI with overground endoscopic (OGE) results. STUDY DESIGN: Randomised balanced 2X5 factorial design. METHODS: A total of n = 200 horses undergoing OGE were randomly assigned into 10 groups (n = 20/group) of different automated endoscopic FIs (no flushing, 60, 120, 180, 240 s) with the endoscope tip positioned either rostrally (position A) or caudally (position B) in the pharynx...

BACKGROUND: Studies of large racing populations have established clear differences in the career profile of stallions, mares and geldings. Multiple studies have also demonstrated positive effects on racing careers for horses that commence racing at a younger age. However, the applicability of these studies to small, native racing populations is unknown and warrants investigation. OBJECTIVES: To provide summary statistics for performance outcomes for the Norwegian-Swedish Coldblooded Trotter and to document and provide evidence on the current differences in racing careers across age at first start groups, sexes and country of birth...
