Computed Tomography Osteodensitometry for Assessment of Bone Mineral Density of the Canine Head—Preliminary Results

Despite bone mineral density (BMD) being regularly measured in human patients, BMD studies in clinical cohorts of dogs is lacking. In order to facilitate BMD assessment and in turn better identify dogs suffering from metabolic bone disease, rapid, easy and precise computed tomography (qCT) techniques are required. In this study we aimed to assess the utility of quantitative computed tomography (qCT) bone mineral density (BMD) measurement of the canine calvarium using a semiautomated osteodensitometry software and define host factors associated with canine bone mineral density in a skeletally healthy population. Calvarial qCT at the level of the temporomandibular joints was performed on 323 dogs using a dedicated osteodensitometry calibration phantom during a clinically indicated head computed tomography (CT). Calvarial BMD was analyzed using a dedicated semiautomatic osteodensitometry software for contouring of the calvarial lamellar bone margins and BMD calculation. The mean duration of the calvarial qCT scanning was 64.6 s, and the mean duration of BMD analysis was 34 s, with a mean of two manual adjustments required for the bone margin tracing. The median BMD of all dogs in our study was 659 mg Calcium hydroxyapatite/mL. There was a negative linear correlation between BMD and body weight, but no correlation with age, sex or neutered status. Canine BMD assessment using qCT of the calvarium is a practical and fast technique that can be added to a clinical CT examination with minimal extra time requirements. Canine BMD host-dependent factors exhibit different relationships from that of humans; however, further investigation is warranted

The National Exercise Referral Framework

A 2013 Review of the HSE funded GP Exercise Referral Programme (GPERP) highlighted the need for a new National Exercise Referral Framework (NERF). The evidence suggests that exercise referral is an effective targeted health intervention for specific patients and with the increasing prevalence of chronic disease it is imperative that we examine, design and progress the implementation of scalable, sustainable evidence-based, interventions, integrated across the health system to improve the health and wellbeing of the population. The development of this proposed National Exercise Referral Framework, commissioned by Health Promotion and Improvement, was led by DCU involving a multi-disciplinary Working Group and supported by a HSE Cross-Divisional Group. We are grateful to the Working Group and in particular to Dr Catherine Woods and the team in DCU for their extensive work and commitment to this project. There are a number of practical steps now required to determine the feasibility of the proposed framework as a national model namely, identification of a sustainable funding model; design and development of chronic disease care pathways and a phased implementation plan that would build on the existing programmes. The Health & Wellbeing Division of the HSE will lead the next phase of this project
