About the unit's research

The Academic Unit, Medicine, Peninsula Health, is comprised of researchers with different and complementary skill sets whose goal is to conduct high quality translational research into chronic conditions affecting the ageing population. Expertise spans from clinical medicine, bioinformatics and imaging, health services research including data linkage, and biostatistics. Major initiatives include the study of poor metabolic health (e.g. obesity, type 2 diabetes) and dementia, cerebrovascular disease and dementia, frailty and delirium in hospitalized older people, novel technologies for designing health service delivery for stroke, and community systems of care for people with dementia. Members of the group have several local, national and international collaborations. Their work is supported by several sources of funding, including NHMRC.

Associate Professor Richard Beare

Bioinformatics and Imaging

Current Projects

  1. Imaging and statistical methods for longitudinal brain imaging studies.
    Brain imaging studies using MRI generate large volumes of raw data that needs to be transformed into forms amenable to statistical analysis. Different types of image and different studies require different approaches. This project develops software processing pipelines to process data from studies run by our group, such as the TASCOG, CDOT, METTS, and within international datasets (ADNI). The project also develops methods for analysis of images from preclinical studies.

  2. Analysis methods for structural covariance.
    Structural covariance is an approach to generating population level networks from brain structural MRI data. This differs from the typical source of brain network information such as diffusion weighted imaging or functional imaging. This project explores sparse methods for generation of structural covariance networks.

  3. Health services planning and optimization using Google maps.
    Travel time is an important part of many health services, such as ambulance transport to hospital emergency departments for acute stroke. This project uses Google maps queries to construct objective estimates travel time that vary with traffic conditions to allow various models of health service delivery to be evaluated and compared.

Current Funding:

  • Brain Research Foundation - Characterising structure-function relationships in childhood stroke using advanced brain imaging
  • NHMRC 1063608 The role of Central Haemodynamics in Type 2 Diabetes Mellitus-related brain disease.

Dr Chris Moran

Geriatrician, NHMRC & ARC Dementia Early Career Research Fellow

Current Projects:

  1. Type 2 Diabetes and pre-clinical dementia - an FDG-PET co-twin study.
    A study comparing neuropsychological, neuroimaging and central haemodynamic measures in a group of middle-aged twins discordant for type 2 diabetes. This study aims to explore the potential vascular and metabolic mechanisms underlying the associations between type 2 diabetes and dementia.

  2. Dementia in Type 2 Diabetes - studying causal mechanisms.
    This set of projects (ADNI, CDOT) explore whether diabetes leads to neurodegeneration over time and how mechanisms such as inflammation, oxidative stress and genes may contribute to the increased risk of dementia in those with type 2 diabetes. Better understanding of these mechanisms will help guide prevention and treatments of dementia.

  3. Melatonin to treat Delirium in Older People.
    A pilot randomized, placebo-controlled double-blinded clinical trial of the effect of melatonin on the management of delirium on older inpatients in sub-acute care.

Current Funding:

  • Caulfield Hospital Major Project Grant
  • Pfizer Neurosciences Project Grant – FDG PET studies in type 2 Diabetes
  • NHMRC 1063608 The role of Central Haemodynamics in Type 2 Diabetes Mellitus-related brain disease.

Dr Nadine Andrew

NHMRC Early Career Fellow, Health Services Research

Current Projects:

1.    Identifying gaps and inequalities in access to GP coordinated care for survivors of stroke (CIA grant)
This is a data linkage project in which data from over 25,000 patients registered in the Australian Stroke Clinical Registry will be linked to data from the Medical Benefits Schedule and Pharmaceutical Benefits Scheme. These data will be used to explore the use of models of enhance primary care in the long-term management of patients with stroke and barriers to access to the care types.

2.    Developing standardised methods for setting patient centred goals in stroke (CIA grant)
In this project we will be developing stanadardised tools to enable clinicians to reliably and efficiently use patient centered goal setting as part of routine discharge care planning.

3.    Reducing disability from stroke by improving access to best practice stroke care in Victoria (CIB grant)
A project testing the effectiveness of using data to drive quality improvement and changes in clinical practice in stroke care

4.    iVERVE – Inspiring Virtual Enabled Resources following Vascular Events pilot project (CIB grant)
A pilot randomized controlled trial testing the feasibility of a novel discharge support program.
