$15 Million Boost Helps Bioengineers Apply Research Into Clinical Practice
The Auckland Bioengineering Institute (ABI) has been awarded $15 million to lead an international collaboration that aims to translate years of clinical research on the mathematical modelling of human physiology into clinical practice.
Funding for the 12
Labours project been awarded through the Ministry of
Business, Innovation and Employment’s (MBIE’s) Catalyst
Strategic Fund, and is one of the largest research grants
that MBIE has awarded the University.
The project is
named in reference to the 12 labours of Hercules, the tasks
Heracles had to complete to be granted immortality, and also
the 12 organ systems of the human body.
The ABI is
engaged in a wide range of clinically oriented projects that
include the mathematical modelling of the cardiovascular,
respiratory, gastrointestinal, lymphatic and musculoskeletal
systems, as well as the brain, the placenta, women’s
pelvic floor muscles and more.
The funding is a timely
recognition of the ABI’s history and impact, the Institute
co-founded at the University of Auckland by Professors Peter
Hunter and Bruce Smaill 20 years ago this year.
The 12
Labours project will draw together and accelerate research
built for the Physiome
Project, the Project led by the ABI under the auspices
of the international Union of Physiological Sciences, to
which dozens of institutions around the world have
contributed.
The overall goal of the Physiome Project is
to build an online computational modelling framework that
integrates mathematical understanding of human biology at
every level, linking genes, proteins, cells, organs and
organ systems. It aims to develop a complete virtual
physiological human, ultimately allowing for
patient-specific diagnosis and treatment.
We need to take
a more mathematical and quantitative approach to healthcare,
says Dr Hunter. “A lot of medical strategies completely
ignore physics,” he says. “Yet complex structures like
human physiology can be described mathematically, and
can be analysed mathematically, using a biophysically based
understanding of human physiology.
Accurate diagnosis
of a medical condition often needs data from medical images,
physiological tests, blood biomarkers and genetic tests.
Linking those together requires quantitative tools based on
multi-scale physiological models.”
The 12 Labours
Project will draw on 20 years of research done at the ABI
using clinical imaging and other forms of diagnostic data,
including data collected from a new generation of
implantable and wearable medical devices, some pioneered by
the ABI, for both diagnostic sensing and therapeutic
intervention.
The project involves three technology
platforms and three ‘exemplar projects’, to demonstrate
the healthcare applications of their multiscale mathematical
modelling.
This includes a focus on pulmonary
hypertension (cardiovascular and respiratory systems), upper
limb rehabilitation (research on the neuro-musculoskeletal
system) and research into the control of organ function by
the autonomic nervous system (maternal health and digestive
function).
Once established, the researchers will be able
to use the Technology Platforms developed in 12 Labours to
implement diagnostic and therapeutic strategies for a number
of other organ systems and clinical procedures.
These
exemplar projects draw on basic research programmes the ABI
has carried out in collaboration with local and
international partners over many years, funded by the Health
Research Council (HRC), the Marsden Fund, the Heart
Foundation, the Auckland Medical Research Fund (AMRF), and
other national funding agencies, and international grants
from organisations such as the Wellcome Trust, the European
Commission, and the US National Institutes of Health (NIH).
This research is often in collaboration with colleagues in
the Faculty of Medical and Health Sciences (FMHS) at the
University and often with the direct involvement of health
practitioners from District Health Boards (DHBs).
The 12
Labours project ultimately aims to develop a framework to
apply the maths in clinical practice – in assessment,
diagnosis and treatment - in a way that will allow for a
more patient-centric assessment of health status than is
currently possible, says Dr Hunter.
“It’s about
enabling clinicians to make more rational decisions,
introducing the power of predictive modelling, and all the
knowledge of physiological function that we have
encapsulated in our models over 20 years.”
Creating an
integrated physiological and monitoring framework and
introducing it into clinical practice is a ‘grand
challenge’ requiring significant international
collaboration. It is also one which the ABI is well-placed
to lead having pioneered multiscale computational physiology
through its leadership of the Physiome Project, having
collaborated with clinical scientists over many years in a
very wide range of clinical imaging projects, and developed
substantial capability in biomedical instrumentation
including in implantable and wearable device
technologies.
To emphasise the importance of applying a
bioengineering understanding of human physiology in clinical
practice, Professor Hunter compares the human body to an
aeroplane.
“We get on an aeroplane, knowing that the
chance of a crash is tiny, because we trust the engineering
processes behind it, scrutinising the plane, maintaining the
engine, correcting things before they go wrong, making sure
we are kept safe. Why should we not demand that for our own
bodies? The problem is that medicine has largely ignored 100
years of advances in engineering physics.
“So this is
about trying to bring engineering disciplines and physics,
together with physiology, into the interpretation of the
human biological system. Sure, the biological system is
complex, but so is an
airbus.”
