Summary
Reasons for performing study

The factors associated with outcome following solar foot penetration involving synovial structures treated using endoscopic lavage have not been described in the UK population.
Objectives

To provide descriptive data on horses with synovial contamination or sepsis following solar penetration in 4 UK equine referral hospitals and to identify specific factors associated with the outcome.
Study design

Retrospective case series.
Methods

Authors: A. Nagy, J. K. Murray and S. J. Dyson
Journal: Equine Veterinary Journal

Reasons for performing the study

There is limited information on risk factors for elimination from endurance rides.
Objectives

To assess risk factors for elimination for lameness and metabolic reasons from Fédération Equestre Internationale (FEI) endurance rides of 80–160 km distance.
Study design

Unmatched case–control.

Reasons for performing the study

To explore whether genetic susceptibility is a potential risk factor for superficial digital flexor (SDF) tendinopathy in Thoroughbred (TB) racehorses.
Objectives

To identify informative single nucleotide polymorphisms (SNPs) that capture genetic diversity across a range of candidate genes and to investigate, in a case–control study, their association with SDF tendinopathy in UK National Hunt TB racehorses in training.
Study design

Case–control candidate gene association study.

A retrospective cohort study was performed to compare the rates of musculoskeletal injury (MSI) in horses receiving local corticosteroid injection (LCI) with those that were untreated and those prior to treatment. Of the 1911 study horses, 392 had been treated. A LCI was defined as any injection of corticosteroid into or adjacent to a synovial structure, muscle, or tendon/ligament. A MSI was defined as any limb injury identified by a veterinarian, following which the horse did not race for at least 6 months, or was retired.

Reasons for performing study

Lameness is a common problem in the horse. Despite this, information on the incidence of lameness in horses in the UK is restricted to studies of lameness in performance horses, racehorses or referral hospital populations.
Objectives

To determine the overall incidence and common causes of lameness in a working horse population and incidence, duration and outcome of conditions observed.
Study design

Prospective questionnaire study.

Summary
Reasons for performing the study

There is limited information on international endurance rides and on risk factors for eliminations.
Objectives

To describe and compare the frequency of occurrence of elimination due to lameness and metabolic reasons from Fédération Equestre Internationale (FEI) endurance rides (≥100 km) during 2008–2011 in all countries and to assess risk factors for elimination due to lameness and metabolic reasons.
Study design

Retrospective unmatched case–control study.

A retrospective cohort study of important musculoskeletal conditions of Thoroughbred racehorses was conducted using health records generated over a 15 year period (n = 5062, 1296 sires). The prevalence of each condition in the study population was: fracture, 13%; osteoarthritis, 10%; suspensory ligament injury, 10%; and tendon injury, 19%. Linear and logistic sire and animal regression models were built to describe the binary occurrence of these musculoskeletal conditions, and to evaluate the significance of possible environmental risk factors.

Objective

To determine the methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Staphylococcus pseudintermedius (MRSP) contamination rate of white coats (WC) and surgical scrubs (SS) worn by personnel at the Ontario Veterinary College Health Sciences Centre (OVCHSC) and to identify risk factors associated with clothing contamination.
Study Design

Cross-sectional study.
Sample Population

Personnel including clinical faculty, house officers, technicians, and veterinary students working at the OVCHSC.

Reasons for performing study

Palmar/plantar osteochondral disease (POD) is a common, debilitating condition in Thoroughbred racehorses; however, training- and racing-related factors associated with this disease are unknown.
Objectives

To determine horse-, racing- and training-related risk factors for POD. The general hypotheses were that early training and racing, and increased intensity of racing and training, lead to increased severity of POD.

Several studies have demonstrated a statistical association between management practices and juvenile osteochondral conditions (JOCC) in foals from birth to 6 months of age, but this association has not been investigated in yearlings. The purpose of the current study was to determine the adjusted effects of management practices on the onset and evolution of JOCC in French yearlings. The study sample consisted of 259 yearlings born on 20 stud farms in Normandy. The breeding conditions of these horses were monitored from 6 to 17 months.
