Journal article details 'multiplicity of barriers' to clinical acceptance of medical laser innovations

17.06.2015

Patience, persistence, financing required for translation of research into application

The dynamic field of medical laser applications continually offers new systems and techniques enabling less invasive or more targeted treatments. But the path from the lab to the clinic can be slowed by "a multiplicity of barriers" requiring patience, persistence, and financial support, note authors of an article published today (16 June) in the Journal of Biomedical Optics, published by SPIE, the international society for optics and photonics.

In "Medical laser application - translation into the clinics", Ronald Sroka, Laser-Forschungslabor, Hospital of Munich University, and his co-authors detail the path to successful implementation with examples of promising technologies and their translation into acceptance in the medical community.

At technical conferences, unmet clinical needs and detailed requests from clinicians are discussed and innovative techniques are introduced, say the authors in detailing the path.

Subsequent research is informed by this interchange of ideas, and includes technicians and companies whose contributions are indispensable in developing prototypes and initiating clinical trials.

Only after clinical testing and comparison with established nonoptical clinical procedures can the positive or negative impact of new biophotonic technologies be assessed - another of the barriers that must be worked through before achieving full acceptance in the medical community.

Technology examples noted in the paper include:

  • a non-invasive optical method implemented in a portable device that provides low-cost, rapid screening for iron deficiency, which is found in particular among infants, young children, adolescents, and menstruating and pregnant women. Adverse effects of iron deficiency include anemia, impaired cognitive development, decreased immune responsiveness, and, when severe, death. Iron supplements are widely used to prevent or correct nutritional iron deficiency, but have been shown to increase the risk of severe illness and death in children when malaria is present. The World Health Organization has concluded that iron supplements should not be given without screening for iron deficiency.
  • novel photonics-based tools to fundamentally change the clinical management of breast cancer - the most common cancer among women worldwide in high-income as well as low- and middle-income countries. Improving the selection of women entering breast cancer screening programs and adjusting the screening frequency based on a personalized risk assessment would lead to a better utilization of available resources, enable detection of predominantly early-stage breast cancer, and reduce the overall cost to health care systems.
  • in neurosurgery, fluorescence methods that permit identification during surgery of residual tumor tissue in treatment of glioblastoma multiforme, the most common form of primary brain cancer in adults. Survival after surgery and radiotherapy is linked to the completeness of tumor removal.
  • a minimally invasive laser treatment to relieve nasal airway obstruction in people with long-term allergies or other conditions. Patients who do not respond to sprays or other pharmacological treatment may require surgery, which is often accompanied by long-term bleeding and further discomfort. Endonasal laser treatments cause limited side effects with little or no bleeding, and result in similar airway clearing.
  • laser treatment of varicose veins, which appear among ~50% of adults in some areas of Europe with symptoms including sensations such as heavy legs, tension, swelling, pain while standing and sitting, discoloring, and phlebitis. In half of cases, patients require surgery. Procedures such minimally invasive endovenous laser therapy have provided relief to the patient with just one puncture.

The article appears in a special section titled "Light for Life" celebrating the International Year of Light and Light-based Technologies 2015 (IYL2015) and paralleling a dedicated session at the at the European Conference on Biomedical Optics (ECBO) running 21-25 June in Munich. Journal of Biomedical Optics publisher SPIE is a Founding Sponsor of the IYL2015 and a sponsor of ECBO.

About SPIE

SPIE is the international society for optics and photonics, an educational not-for-profit organization founded in 1955 to advance light-based science and technology. The Society serves nearly 264,000 constituents from approximately 166 countries, offering conferences and their published proceedings, continuing education, books, journals, and the SPIE Digital Library in support of interdisciplinary information exchange, professional networking, and patent precedent. SPIE provided more than $4 million in support of education and outreach programs in 2014. http://www.spie.org

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
