CHHM ProjectEvaluating the contribution of bone micro-architecture, density and bonestrength to fracture at clinically relevant sites using a novel instrument: an Xtreme CT study. I propose to examine the efficacy of Xtreme CT to predict mechanical bone strength at the two most common clinically relevant fracture sites: the proximal femur and distal radius. My research questions are: 1) Can the Xtreme CT provide an accurate assessment of bone size, shape and strength of the proximal femur and distal radius in cadaveric specimens?; 2) what are the determinants of failure load for the proximal femur and distal radius?; and 3) can bone outcomes at the distal radius predict failure load at the proximal femur? This new knowledge can be applied to intervention studies to impact quality of life, independence and mobility within a vulnerable population – the frail elderly. Finally, our ability to identify hip and forearm fracture risk may allow us to consider prophylactic interventions to prevent recurrent hip fracture in the future. |

For her thesis, Mary will use the BC Linked Health Database to study the potential benefits of statins in patients with rheumatoid arthritis (RA). Affecting approximately 300,000 Canadians, RA is a chronic, disabling inflammatory disease in which the immune system attacks its own joints and organs. Aside from painful symptoms, people with RA are more likely to get heart disease and die at a younger age. Statins are drugs that lower cholesterol and used to treat and prevent heart disease. Recent work suggests that they also have anti-inflammatory effects. Because of these lipid-lowering and anti-inflammatory properties, statins may provide a dual benefit to people with RA by reducing heart disease and improving symptoms.

d'Entremont, AgnesPh.D. Candidate, Department of Mechanical Engineering, Division Orthopaedic Engineering Research agnesgd@interchange.ubc.ca Supervisor: Dave Wilson Co-Supervisor: Alex MacKay |
CHHM ProjectAgnes' research is focused on links between knee mechanics and cartilage changes. To explore these links, she is studying high tibial osteotomy as a distinct mechanical change which has been shown to cause positive cartilage changes. High tibial osteotomy is often thought of as a stop-gap measure for bow-legged people who are too young to have a total knee replacement, however the distinct advantages of a less radical surgery and retention of natural joint surfaces make it an attractive option for some patients. Agnes is using MRI techniques to measure both knee movement and cartilage health. |

Lindsay NagamatsuM.Sc. Candidate, Department of Psychology lindsay@psych.ubc.ca |
Lindsay completed her Bachelor of Arts degree at UBC in 2006. Her research background is in studying visual attention using brain imaging techniques, including event-related potentials (ERPs) and fMRI. Her current research interests are in assessing fall risk via deficits in visual attention in seniors. CHHM ProjectThe Role of Cognitive Deficits Associated with Fall Risk in the Elderly. The main goal of this research is to determine what cognitive factors and brain areas play a role in fall risk in the elderly. Falls are a major health care concern, and therefore the identification of the underlying causes of falling will provide us with the ability to assess fall risk in adults and help prevent falls. This project aims to determine whether deficits in visual-spatial attention play a key role in increased fall risk. Visual attention is assessed using basic paradigms while in an fMRI scanner. Fallers and non-fallers will be compared in order to determine if any differences between the two groups exist. |

Eric Sayre completed a PhD in Statistics in the Department of Statistics and Actuarial Science at Simon Fraser University. He is currently a postdoctoral fellow jointly in the School of Population & Public Health, and the Department of Medicine at the University of British Columbia. His research is undertaken out of the Arthritis Research Centre of Canada. His co-supervisors are Dr. Jacek A. Kopec of the School of Population & Public Heath, and Dr. Jolanda Cibere of the Department of Medicine. Eric is an awardee of a Canadian Arthritis Network Postdoctoral Fellowship Award. Eric's work is on an application in osteoarthritis research of his new method of unsupervised learning (hypothesis generation) designed specifically for mixed-type data, developed during his PhD research. Variable-Weighted Ultrametric Optimization for Mixed-Type Data (VWUO-MD) will be useful in identifying complex co-morbidity patterns, as well as finding new multivariate associations between a multitude of health conditions, socio-economic and geographic factors, and health services utilization patterns. VWUO-MD will be a valuable tool for exploiting the increasing multitude of highly multivariate, mixed-type population and administrative health databases available to researchers, in developing new, previously unthought-of hypotheses. |

Scott, AlexanderPh.D. Student, Medicine |
CHHM Project
My work is focused on understanding the molecular mechanisms of tendon overuse injuries (tendinopathy). Using a variety of experimental approaches, I aim to answer some basic, clinically oriented questions. What is the initial event in tendinopathy development? The traditional paradigm holds that collagen microtrauma is responsible. However, new research shows tendon fibroblasts (tenocytes) are responsive to load - like osteoblasts, they are mechanosensitive. I am currently focusing on the role of tenocytes as an initiating factor in tendinopathies. My work shows that depending on the type and magnitude of loading, tenocytes may die (via apoptosis), proliferate (via IGF-I signaling) or undergo metaplasia (becoming more like cartilage cells). My methods include analysis of clinical tendon biopsies and surgical outcomes, cell and organ culture, Flexercell, flow cytometry, Western blot, cell viability assays, immunohistochemistry, laser capture microdissection, and animal models of overuse injury. |
