Altered gene expression in the liver and small intestine of horses with equine neuroaxonal dystrophy. Equine neuroaxonal dystrophy/degenerative myeloencephalopathy (eNAD/EDM) is the second most common diagnosis of spinal ataxia in horses in the United States. The disease develops due to a combination of vitamin E deficiency and an unknown genetic risk factor(s), and there currently is no effective treatment. Objective: We performed transcriptomic profiling of the liver and small intestine of horses with and without eNAD/EDM, as both tissues are the main locations for absorption, metabolism, and delivery of vitamin E to the nervous system. Methods: Case-control exploratory study. Methods: Post...
Maxillary and mandibular fracture repair using a modified bis-acryl reinforced interdental wiring technique: Description of the technique and report of 11 cases. Repair options for maxillary and mandibular fractures in horses are dictated by the proximity of dentition, fracture configuration, and implant design. Jaw fractures can be repaired by minimising tension forces via intraoral splint constructs when dentition is present on either side of the fracture line. This repair option reduces iatrogenic damage to dentition while achieving reduction and stability until appliance removal. Objective: To first report a modified technique for jaw fracture repair in horses with cadaveric example images. Second, to report the clinical outcome of maxillary and ma...
Pneumocoele sinus: Computed tomographic findings and surgical approach in a 2-year-old Cob filly. Pneumosinus dilatans and pneumocoele sinus describe abnormal hyperpneumatisation of paranasal sinuses, with the latter being accompanied by thinning of bony walls. Although recognised in human and equine medicine, to the authors' knowledge, this condition's computed tomography (CT) findings and successful surgical approach in horses have not previously been reported in conjunction. Advanced imaging, particularly CT, is pivotal for identifying abnormal sinus expansion and associated nasal obstruction. Methods: Case report. Conclusions: A 2-year-5-month-old Cob filly presented with a 1-month his...

Oscillometric assessment of bronchodilator response in horses with severe asthma during remission. During clinical remission of severe equine asthma (SEA), affected animals can be challenging to distinguish from healthy horses. In humans, the degree of bronchodilation achieved with a β-adrenergic bronchodilator is helpful in differentiating asthmatics from healthy subjects. Objective: To determine whether the response to an inhaled bronchodilator improves the sensitivity of oscillometry in detecting subclinical airway obstruction in horses with asthma. Methods: In vivo experiments. Methods: Nine control university-owned horses and 10 SEA horses in remission from a research herd were studie...
Similar locomotor patterns across Quarter Horse disciplines inform lameness assessment. Lineage-based selection is central to the Quarter Horse industry and is often justified by the assumption that morphology determines locomotor function. However, objective evidence linking static conformation to discipline-specific locomotor behaviour under standardised conditions remains limited. Objective: To investigate whether morphological differences among Quarter Horse disciplines are associated with distinct locomotor patterns or whether locomotor function converges across disciplines despite morphological variation. Methods: Cross-sectional. Methods: Barrel racing, reining, and ranch ...
