Equine parvovirus hepatitis. Equine parvovirus hepatitis (EqPV-H) was first described in 2018 in a fatal case of Theiler's disease which followed the administration of an equine-origin biological product. The virus has since been frequently identified in serum and liver tissue of horses affected by Theiler's disease-an acute, severe hepatitis characterised by fulminant hepatic necrosis with a fatal outcome in most cases. EqPV-H is hepatotropic, appears to be associated with subclinical to severe hepatitis in horses, and is a likely cause of Theiler's disease. Although this disease is most frequently reported following the...
Long-term athletic performance in sport horses after desmotomy of the accessory ligament of the deep digital flexor tendon. Outcome after desmotomy of the accessory ligament of the deep digital flexor tendon (AL-DDFT) to treat flexural deformity of the distal interphalangeal joint has been reported to be excellent. However, no studies have compared long-term athletic performance of sport horses exposed to desmotomy of the AL-DDFT to that of matched controls. Objective: The objective of this study is to compare long-term athletic performance in sports horses subjected to desmotomy of the AL-DDFT with the performance of matched controls.

Continuous versus discrete data analysis for gait evaluation of horses with induced bilateral hindlimb lameness. Gait kinematics measured during equine gait analysis are typically evaluated by analysing (asymmetry-based) discrete variables (eg, peak values) obtained from continuous kinematic signals (eg, timeseries of datapoints). However, when used for the assessment of complex cases of lameness, such as bilateral lameness, discrete variable analysis might overlook relevant functional adaptations. Objective: The overall aim of this paper is to compare continuous and discrete data analysis techniques to evaluate kinematic gait adaptations to lameness. Methods: Method comparison. Methods: Sixteen healthy ...

Detection of synovial sepsis in horses using enzymes as biomarkers. Synovial sepsis is a commonly occurring, potentially career-ending or even life-threatening orthopaedic emergency. Diagnosis of synovial sepsis is currently primarily based on synovial fluid analysis, which often leaves diagnostic ambiguity due to overlap of clinicopathological parameters between septic and aseptic inflammatory synovitis. Objective: To evaluate the reliability of lysozyme (LYS), myeloperoxidase (MPO) and elastase (ELT) as biomarkers for synovial sepsis in horses using a photometric assay to measure increased enzyme activity. Methods: Prospective, single-blinded, analytical, cl...

Seminal plasma, and not sperm, induces time and concentration-dependent neutrophil extracellular trap release in donkeys. In several mammalian species, acute endometritis driven by the recruitment of polymorphonuclear cells (PMN) occurs in response to semen. These PMNs release DNA to form neutrophil extracellular traps (NETs) in cattle, horse and human, leading to sperm entrapment. While there is no evidence of this phenomenon occurring in donkeys, artificial insemination (AI) with frozen-thawed semen, which results in very poor pregnancy rates, leads to a large PMN recruitment to the uterus. Objective: To investigate whether donkey semen can trigger NET release (NETosis) and if excessive NETosis occurs in respon...
Laparoscopic closure of the vaginal rings in the standing horse using a tacked intraperitoneal slitted mesh (TISM) technique. Indirect inguinal herniation (IIH) is a potentially life-threatening condition in stallions. The ideal preventive measure for breeding stallions ensures a minimally invasive closure of the vaginal ring that avoids recurrence of IIH while preserving both testicles. Objective: To describe a minimally invasive laparoscopic tacked intra-peritoneal slitted mesh (TISM) technique in the standing horse to close the vaginal rings and to evaluate its efficacy in preventing recurrence of IIH in stallions. Methods: Retrospective case series. Methods: Medical records of 17 stallions with a history of IIH w...
