Long-term Management

Face validity of a proposed tool for staging osteoarthritis: Canine OsteoArthritis Staging Tool (COAST).

Summary:

This article outlines the rationale and thought processes behind the construction of this proposed instrument and the ‘item generation’ — determination by expert opinion of what the instrument should contain and look like (face validity). It gives a detailed overview of COAST, and practical details on how it is proposed to be used.

Conclusion:

This report describes a novel instrument developed by an expert panel to facilitate diagnosis of OA through standardized and guided assessment. Ultimately, an effective staging tool like this may help improve pain control and general clinical management of dogs with OA by providing standardized ‘scores’ over time that can be related to treatment efforts. With COAST, the authors are proposing a schematic approach to diagnosing and staging canine OA, utilizing inputs from the pet owner and from the veterinarian consultation and examination.

Evaluation of the effect of limited food consumption on radiographic evidence of osteoarthritis in dogs.

Summary:

To determine prevalence of radiographic evidence of osteoarthritis in 4 diarthrodial joints of dogs with restricted feed intake, compared with dogs without restricted feed intake.

Conclusion:

Prevalence and severity of osteoarthritis in several joints was less in dogs with long-term reduced food intake, compared with control dogs. Food intake is an environmental factor that may have a profound effect on development of osteoarthritis in dogs.

Influence of lifetime food restriction on causes, time, and predictors of death in dogs.

Summary:

To describe effects of lifetime food restriction on causes of death and the association between body-mass characteristics and time of death in dogs.

Conclusion:

Results were similar to results of diet restriction studies in rodents and primates, reflecting delayed death from species- and strain-specific intrinsic causes. Clinicians should be aware that unplanned body mass changes during mid- and later life of dogs may indicate the need for thorough clinical evaluation.

Lifelong diet restriction and radiographic evidence of osteoarthritis of the hip joint in dogs.

Summary:

To evaluate the effects of diet restriction on development of radiographic evidence of hip joint osteoarthritis in dogs.

Conclusion:

Restricted feeding delayed or prevented development of radiographic signs of hip joint osteoarthritis in this cohort of Labrador Retrievers. Lifetime maintenance of 25% diet restriction delayed onset and reduced severity of hip joint osteoarthritis, thus favorably affecting both duration and quality of life. In addition, the data indicated that development of hipjoint osteoarthritis was not bimodal in these dogs but occurred as a continuum throughout life.
