Background Subchondral bone plays an important role in the pathogenesis of radiographic osteoarthritis (OA). However, the bony changes that occur in hand OA (HOA) are much less understood. This study aimed to describe the association between radiographic HOA and high-resolution peripheral quantitative computed tomography (HRpQCT) measures of the ha...

Objective: To determine associations between chronic plantar heel pain (CPHP) and MRI- and US-derived imaging biomarkers. Methods: We compared 218 participants with CPHP with 100 age- and sex-matched population controls. We assessed imaging biomarkers on MRI (calcaneal bone marrow lesions (BMLs), plantar fascia signal and thickness, spurs and fa...

Chronic plantar heel pain (CPHP) is associated with calcaneal bone spurs, but its associations with other calcaneal bone features are unknown. This study therefore aimed to determine associations between having CPHP and bone density and microarchitecture of the calcaneus. We assessed 220 participants with CPHP and 100 age- and sex-matched populatio...

This study reported that the transitional zones in older adults were enlarged at the expense of the compact-appearing cortex with a greater porosity in all cortical sub-compartments. The magnitude of differences in areal and volumetric bone mineral density (aBMD, vBMD) between older and younger groups was similar.IntroductionAging is strongly assoc...

Introduction/background: Both areal bone mineral density (aBMD) and bone microarchitecture have been associated with vertebral deformity (VD), but there are limited data on the utility of bone microarchitecture measures in combination with aBMD in discriminating VD. This study aimed to describe whether radial bone microarchitecture measures alone...

Objective To describe associations between hand abnormalities on MRI or radiographs (X-ray) and pain and function in a cross-sectional study of community-based older adults. Methods Distal and proximal interphalangeal index finger joints (n=221) were examined using MRI, X-ray, and hand examination. Hand pain, function, and stiffness were assessed u...

Objective: To describe cross-sectional associations between features observed on ultrasound (US) or clinical joint examination and hand symptoms amongst community-dwelling older adults (n=519), and determine whether such associations are independent of age, sex, BMI, and other imaging features. Methods: Hand pain, function, and stiffness were as...

The microcirculation in adipose tissue is markedly impaired in type 2 diabetes (T2D). Resistance training (RT) often increases muscle mass and promotes a favourable metabolic profile in people with T2D, even in the absence of fat loss. Whether the metabolic benefits of RT in T2D are linked to improvements in adipose tissue microvascular blood flow...

Background: In obesity and type 2 diabetes mellitus (T2D), adipose tissue expansion (because of larger adipocytes) results in reduced microvascular density which is thought to lead to adipocyte hypoxia, inflammation, and reduced nutrient delivery to the adipocyte. Adipose tissue microvascular responses in humans with T2D have not been extensively...

To estimate the heritability of bone geometry, volumetric bone mineral density (vBMD) and microarchitecture of trabecular (Tb) and cortical (Ct) bone measured by high resolution peripheral quantitative computerised tomography (HRpQCT) at the distal radius and tibia and to investigate the genetic correlations of these measures. Participants were 177...

Objective: Insulin increases glucose disposal in part by enhancing microvascular blood flow (MBF) and substrate delivery to myocytes. Insulin's microvascular action is impaired with insulin resistance and type 2 diabetes. Resistance training (RT) improves glycemic control and insulin sensitivity, but whether this improvement is linked to augmented...

Physical inactivity and overweight and obesity are more prevalent among rural than urban populations. This study aimed to review published evidence of the effectiveness of interventions to increase physical activity (PA) and/or decrease sedentary behaviour (SB) among rural adults and to identify factors associated with effectiveness. Seven electron...

Background While both genetic and environmental factors affect areal BMD (aBMD), as much as 80% of variation in BMD is attributable to genetic factors [1]. aBMD measured by dual x-ray absorptiometry (DXA) is used as a surrogate measure for bone strength and is the gold standard for diagnosis of osteoporosis. However, structural abnormalities indepe...

Introduction Effective interprofessional communication is intrinsic to safe health care. Despite the identified positive impact of collaborative radiographic interpretation between rural radiographers and referrers, communication difficulties still exist. This article describes the strategies that Australian rural radiographers use for communicatio...

Purpose: Despite increasing evidence that the physical environment impacts on physical activity among urban-dwellers, little attention has been devoted to understanding this relationship in rural populations. Work in this area is further hindered by a lack of environmental measures specifically designed for rural settings. This qualitative study a...

Issue addressed: Social-ecological models of health behaviour acknowledge environmental influences, but research examining how the environment shapes physical activity in rural settings is limited. This study aimed to explore the environmental factors that act as barriers or facilitators to physical activity participation among rural adults. Meth...

The role of Australian rural radiographers in radiographic interpretation, communication and disclosure of their radiographic opinion with a specific focus on plain film radiography was examined in a two phase, exploratory interpretive study. Data were collected using questionnaires and interviews and analysed thematically. This reports one of the...

In this chapter we explore key issues in making research capacity building (RCB) work in primary healthcare. Drawing on a select review of the RCB literature, the paper identifies the knowns and unknowns about research capacity building for primary healthcare. It examines key definitions of RCB, explains why RCB matters, identifies some key challen...
