The University of Glasgow, School of Veterinary Medicine, is calling for help with research into the prevalence of pseudopregnancy in spayed bitches.
The research takes the form of a survey being conducted amongst a representative sample of veterinary surgeons by Pippa Hutchison, Dr Tim Parkin, Caroline Warnes and Dr Philippa Yam.
In particular, the research aims to gather data looking into how often veterinary surgeons are diagnosing and treating pseudopregnancy, and how frequently the condition occurs both before and after spaying.
Tanya Leslie MRCVS from Ceva Animal Health, sponsors of the work, said: “Ceva is delighted to have been given the opportunity to support this work to investigate and raise awareness of this important issue”.
The questionnaire is being sent out towards the end of this month. If you're one of the recipients, there's the added incentive of being entered into a draw for a £300 cash prize if you complete the questionnaire and return it by the 13th November.
The researchers say that after this initial work, they plan a prospective study establishing the wider incidence of pseudopregnancy in both entire and spayed bitches.
A new study published in Equine Veterinary Journal's (EVJ) in partnership with the American Association of Equine Practitioners, has shown that a wireless, inertial sensor-based system can effectively measure a horse's response to a flexion test.
The authors say that opinions on the value of flexion tests in assessing equine lameness have been divided for many years, but their research should turn what has always been regarded as a subjective process into a wholly objective one.
Flexion tests are used routinely in horses with subtle or imperceptible lameness, to exacerbate the problem and make it apparent to the observer. The test involves applying a short period of pressure to the joints of the limb before re-examination, and evaluating any change in gait. However, flexion tests rely on the ability of the observer to identify and interpret changes in the horse's gait and in that respect these tests are subjective and not necessarily consistent between observers.
The research study was conducted by orthopaedic surgeons based at the University of Glasgow's School of Veterinary Medicine1. A total of 17 healthy adult horses, all in work, were fitted with sensors before being trotted in a straight line. The sensors measured vertical pelvic movement asymmetry for both right and left hind limb strides and the average difference in maximum and minimum pelvic height between right and left hind limb strides. A hind limb was randomly selected for 60 seconds of proximal flexion, after which the horse was trotted for a minimum of 10 strides. Response to the flexion was blindly assessed as negative or positive by an experienced observer.
John Marshall, lecturer in equine surgery at the University of Glasgow, who led the study, said: "A positive response to flexion resulted in significant changes to objective measurements of pelvic symmetry, supporting the use of inertial sensor systems to objectively assess response to flexion tests."
Professor Jim Moore, North American Editor of the EVJ, said: "The introduction of an objective approach to documenting lameness examination will not only help vets and trainers to investigate equine lameness more accurately. It will also serve as an unbiased method of communicating lameness examination findings among vets, trainers, farriers and other professionals."
The next phase of research will be to establish cut-off values for objective assessment of other equine lameness diagnostic procedures, such as nerve blocks.
