E-health is the healthcare of
tomorrow, which is why the Dutch Government is taking more initiatives
to make it a reality. BioSpectrum gives a brief snapshot of six
high-end innovative technologies which could change patients’ quality
of life
A visit to the community centers in the Doornakkers
neighborhood in the province of Eindhoven, and one would not fail to
notice the extent to which e-health services has percolated into the
daily lives of the Dutch population. Ms Ayse Artúrk, 59, met
with an accident two years ago, which caused an injury to her leg. Old
age coupled with immobility caused by the injury, made it difficult for
her to physically go to the trainer for exercises and her general
practitioner for regular check-ups. E-health made her life easy.
Through a whole menu of ICT services provided by the ‘Living Lab’
project, which aims at providing e-health services to the elderly
population, Ms Artúrk can now, at the click of a button,
virtually connect to her physical trainer, sitting in another location
of the neighborhood, and her general practitioner for her weekly
check-ups rather than physically going to the clinic.
The Dutch healthcare system today faces three major worrying trends –
increase in chronic illness and aging population, deficit in nursing
and caring staff and above all, public healthcare costs rising faster
than the economic growth. In 2010, Netherlands saw €63 billion being
spent on healthcare. The Ministry of Health, Wellbeing and Sports is
thus looking at a host of e-health solutions which include application
tools for elderly care, tools for chronic diseases, applications for
interaction between professionals (tele-dermatology and expert systems)
and lastly, initiating electronic health record (EHR). By 2020,
e-health services would be available at the national level and in 2012
e-health services for diabetes and chronic heart failure would be
available. Collaborative partners for this initiative include Achmea,
Menzis, KPN, Philips, Rabobank, and TNO enZIP/VWS.
The Dutch Ministry of Economic Affairs organized a media tour to
showcase the latest e-health initiatives and high-end medical
technologies that have been developed and are expected to be
implemented by Dutch universities, spin-off companies and
organizations. A brief snapshot of some of these technologies:
E-Health = Healthcare of the Future
Instantaneous, ultra-sensitive and handy detection of micro-organisms
and biomarkers with Lab-on-a-Chip Interferometer Nanotechnology from
Ostendum — a spin-off company from MIRA, University of Twente’s (UT)
Research Institute for Biomedical Technology and Technical Medicine:
Ostendum has developed an easy-to-use, ultra-sensitive sensor chip,
which in a span of five minutes, detects the presence of
micro-organisms which including specific bacteria, virus and even
proteins and DNA/RNAs. The technology based on the Lab-on-a-Chip and
Interferometer nanotechnology was originally developed at the UT. For
instance, this chip takes five minutes to detect an influenza virus
while a normal PCR test would take five-to-six hours. The chip takes
three minutes to detect proteins released during traumatic brain
seizures as compared to the usual eight hours using a PCR test.
Validations have been done for herpes viruses, vaccinia virus,
influenza A (H1N1) in serum (now saliva test being prepared), traumatic
brain injury (TBI) markers and cardiac biomarkers.
Determination of an appropriate cancer therapy using magnetic particles
at Medical Cell Bio Physics - a spin-off from MIRA, UT: The 15-member
team at Medical Cell Bio Physics in collaboration with Veridex, US, has
pioneered the development of a technology which will test and determine
the right therapy for cancer by counting the number of circulating
tumor cells (CTCs) in the blood. The presence of a high count of CTCs
is indicative for poor prognosis and suggests an ineffective therapy if
not eliminated after three-to-four weeks of therapy. This technology
developed by Dr Leon Terstappen uses immuno-magnetic particles and
through its magnetic force attracts the CTCs binded to the blood
sample. Depending on the tumor cells, doctors can determine not just
the efficacy of the patient’s current therapy but also suggest an
appropriate cancer therapy if the exist one proves to be inefficient.
While, in current practices, the efficacy of a cancer treatment can be
determined only after 20 weeks, in this case, the efficacy can be
determined within the first week itself.
Bone growth using ceramics from Progentix – a spin-off from MIRA, UT:
Progentix has brought in a different facet to regenerative medicine by
using synthetic biomaterials for bone growth rather than filing the
defect by taking the bone from the human body. The team identified the
disadvantages of choosing treatments using bone parts from the human
body. Cell therapy too had its own set of limitations. Moreover, for
the increasing aging population in the West, such treatments are not
viable. The result was the creation of synthetic ceramic, materials
patented micro structures, whose chemical properties are acceptable by
the body, has the ability to form bones and instruct the body without
having to add cells through stem cell therapy or other growth factors.
Early diagnosis of prostate cancer by contrast-ultrasound diffusion
imaging from Eindhoven University of Technology, Academic Medical
Center, Amsterdam; and Catharina Hospital, Eindhoven: Scientists and
doctors have come up with a new ultrasound imaging method for prostate
cancer localization called the Ultrasound Contrast Agent (UCA)
diffusion. The idea here was to come up with a breakthrough
non-invasive imaging technology for men. Local diffusion is estimated
by transrectal ultrasound imaging of an ultrasound contrast-agent bolus
passing through the prostate circulation after a peripheral intravenous
injection. These microbubbles after having being injected to the blood
stream are then induced with ultrasonic waves which propels oscillation
of the agents in a non-linear manner. Indicator Dilution Curve (IDC)
measurement at each pixel is tracked followed by quantification of
local UCA dispersion by IDC analysis which in-turn diagnoses whether a
patient is suffering from prostrate cancer.
Development of online risk test to detect a patient’s risk of
developing preventable diseases from the Doctors at Bronovo Hospital,
Hague: After five years of intensive research doctors at the Bronovo
Hospital, Hague have developed a new and comprehensive online risk test
for 28 types of preventable diseases. Launched nation-wide on January
4, 2011, the website requires a patient to fill a questionnaire which
takes 30-40 minutes and the results indicate whether the patient is at
risk of developing one or more preventable diseases and whether he/ she
should go for a screening test. At the end of the result, the website
also gives diet suggestions for all the 28 diseases. Follow up of the
visit to the general practitioner (GP) is also tracked. Results
indicate a gradual change in the number of patients adopting healthy
habits like exercising, reduced intake of alcohol and smoking and
taking care of their diet. The pilot studies for this test involved 16
GPs and 20,000 patients.
Interventions via internet for psychological patients from Trimbos
Institute, Utrecht: Scientists at the Trimbos Institute have come up
with e-mental health services for patients suffering from psychological
problems, who otherwise could not be traced. Speared by the Innovation
Center of Mental Health and Technology (I.COM) the project called
‘Mental Vitality’ has 16 sub-projects. Two portals are being developed,
one for the youth and the other for adults. These contain an overview
of all the online resources for mental problems. A new e-self help
intervention – the Mental Vitality Module – is being developed. For
people who receive treatment for depression, there will be a new module
for relapse prevention. Within the Mental Vitality program, a
standardized indication instrument with clear protocols is being
developed. Its purpose is to provide appropriate prevention
interventions at the right time within the care chain of prevention,
treatment and aftercare.
