Research Reports on Near Infrared Research from University of British Columbia Provide New Insights
2012 JUL 25 (VerticalNews) -- By a News Reporter-Staff News Editor at Telecommunications Weekly -- Investigators publish new report on Near Infrared Research. According to news reporting originating from Vancouver, Canada, by VerticalNews correspondents, researchers stated "Near infrared (NIR) spectroscopy is an established non-invasive optical technique for measuring changes in haemoglobin concentration occurring in the microcirculation in real time. NIR spectroscopy parameters refect change in tissue haemodynamics and oxygenation and can contribute important physiologic insights when used alone or interpreted in parallel with other conventional measurements."
Our news editors obtained a quote from the research by the authors from the University of British Columbia, "The broad use of NIR spectroscopy in research is not matched by clinical applications; reasons include limitations inherent to the technique, using instruments designed for research at the bedside, ambiguity regarding what NIR spectroscopy measures, defciencies of early algorithms, and understandable expectations by clinicians that NIR spectroscopy data are reproducible and specific enough for clinical decision making. Such issues could be addressed by appropriate collaboration where clinicians drive the questions which NIR spectroscopy is to answer, researchers contribute to monitoring methodology, device design and data analysis/algorithms and both groups utilise physiologic knowledge and practical lessons learned from prior NIR spectroscopy studies when interpreting data. NIR spectroscopy applications in urology are recent and offer clear opportunities for clinicians and researchers to collaborate. Urology is a field where current clinical investigations are limited in terms of the physiologic information they provide and because the principal test used for evaluation of the many people who have problematic lower urinary tract dysfunction is invasive in nature. Hence the rationale for non-invasive transcutaneous optical monitoring of the bladder during voiding as, when the organ contracts, changes in oxygenated and deoxygenated haemoglobin occur which allow haemodynamic variations and alterations in oxygen supply and demand to be inferred. Different patterns of change are evident in healthy and diseased tissue; these patterns refect the effects of physiologic events observed using NIR spectroscopy to study other tissues and provide novel insights into the causation of voiding dysfunction. This review of the evolution of a wireless methodology for bladder studies includes examples of effective clinician researcher collaboration, reveals how miniature NIR spectroscopy devices make monitoring in ambulant subjects straightforward and makes possible studies in special populations such as children and patients with spinal cord injury."
According to the news editors, the researchers concluded: "Hence, such wireless devices represent an advance of relevance in urology and an opportunity to expand research in other fields and progress with translation of NIR spectroscopy into other relevant clinical arenas."
