Advanced Image Analysis Can Provide Better Risk Assessment In Hardening Of The Arteries
Ultrasound examination of the carotid artery is a patient-friendly and inexpensive method for assessing atherosclerosis and thereby predicting the risk of cardiovascular diseases. Peter Holdfeldt, who recently defended his doctoral thesis at Chalmers University of Technology in Sweden, has developed new analytical methods for ultrasound images that can provide more reliable and more exact assessments of atherosclerosis.

UCF Team's Advanced Nerve Cell System Could Help Cure Diabetic Neuropathy, Related Diseases
Multiple sclerosis, diabetic neuropathy, and other conditions caused by a loss of myelin insulation around nerves can be debilitating and even deadly, but adequate treatments do not yet exist. That"s in large part because of deficiencies in model research systems. In an upcoming issue of the journal Biomaterials, a UCF team addresses this problem with a report on the first lab-grown motor nerves that are insulated and organized the same way they are in the body. The group"s model system, along with further advances now within reach, could dramatically improve understanding of the causes of myelin-related conditions, and enable discovery and testing of new drug therapies.

Critics Escalate Attacks On Health Care Overhaul
Tensions are showing as health reform continues to be center stage on the President"s and Congress" domestic policy agenda. The Associated Press reports that "President Barack Obama has learned the lessons of Bill Clinton"s failed bid to overhaul the nation"s health care system. Too well, in fact, say fellow Democrats angry over [Obama"s] refusal to intervene while a conservative proposal advances in the Senate," feel Obama has "over-learned the lessons of 1993 and is bending over too far to attract GOP support in the Senate." Obama supports a public option for health insurance, but "wants to avoid issuing nonnegotiable demands early in the legislative process," say White House aides. "Insurance companies oppose the public option proposal. Their cause was hurt this week when congressional investigators said two-thirds of the U.S. health insurance industry used a faulty database that overcharged patients for seeing doctors outside their insurance network, costing Americans billions of dollars in inflated medical bills" (Babington, 6/26).

Health System Lessons From Black Saturday

The Victorian hospital system coped well in the wake of the Black Saturday bushfires of February 2009 but new research, published in the Medical Journal of Australia, suggests the lessons learned over this time must be used to further strengthen the State"s prevention and medical response systems. Prof Peter Cameron, an emergency physician at The Alfred hospital and Monash University and his co-authors examined how the Victorian State Trauma System responded to the bushfires over the first 72 hours. The intensity and speed of the fires meant that most people injured in the bushfires either died or survived with minor injuries. The statewide and national responses were triggered early and allowed the acute medical system to cope well with the relatively small number of surviving patients with serious burns. Despite low numbers of patients with serious burns, substantial surgical res were required during the first 72 hours - with adult burns patients at The Alfred collectively requiring close to 50 hours in theatre during that time. Prehospital triage was essential in managing the large number of people with minor ailments to avoid overloading the major burns centres. Fortunately, a well-planned response, and strong prehospital triage system, ensured that patients with serious burn injuries received early treatment at Victoria"s major burns centres. Patients with minor conditions were managed well, either at scene or nearby hospitals. Non-burn trauma and other emergencies were managed at other Melbourne hospitals. The Alfred managed 20 patients and the Royal Children"s Hospital four patients with serious burns. One patient admitted to the Royal Children"s Hospital and two at The Alfred died from their injuries. The major burns centre continued to have substantial surge capacity during the bushfire emergency. Although the number of surviving patients with severe burns was relatively low on this occasion, health authorities must be prepared to deal with disasters that result in even greater numbers of people suffering serious burns in the future. "The Australian Bureau of Meteorology has predicted warmer conditions in the south-eastern states in the future, making it likely that the conditions which led up to the bushfires will be repeated," Prof Cameron said. "Should fires occur and advance into more built-up areas, there may be a much higher number of deaths and severe injuries."
