(Press-News.org) Current training programs may not effectively prepare firefighters for the range of scenarios they are likely to encounter, according to human factors/ergonomics researchers Michael R. Baumann, Carol L. Gohm, and Bryan L. Bonner. In their October 2011 Human Factors article, "Phased Training for High-Reliability Occupations: Live-Fire Exercises for Civilian Firefighters," the authors assess the value of current scenario-based training programs.
Firefighters must make complex decisions and predictions and must perform extreme tasks at a moment's notice. Failure to keep a level head in the face of a dangerous situation may result in disastrous consequences. An effective training program that prepares firefighters to handle unanticipated changes may be the key to maintaining low stress levels and preventing stress-related health issues.
The most common form of training exposes firefighters to one or a very small set of live-fire scenarios designed to reduce stress and encourage calm decision-making skills. But repeated exposure to the same scenario may fail to adequately prepare firefighters for changing situations, as lessons learned in that scenario may not transfer to a different scenario.
In the Baumann et al. study, firefighter trainees performed a variety of drills, first repeating a drill in one type of building (six stories, one room on each floor) and then, in a subsequent training, performing drills in a different type of building (two stories, multiple rooms on each floor). As expected, trainees reported reduced stress and fewer performance problems in subsequent repetitions of one scenario but a reversion to pretraining levels of stress with the new scenario.
"If you learn the scenario, you can predict what will happen in that one scenario, but you can't predict what will happen in situations that look a little different," said Baumann. "If you learn general principles, then you can predict what is going to happen in a wide range of situations."
The authors suggest that trainers should increase the range of scenarios to which firefighters are exposed. Desktop-based simulators are available to supplement live-fire training with a variety of scenarios to enable trainees to learn basic principles, even though such simulators cannot replicate a live-fire environment.
"Repeated high levels of stress are associated with a host of health problems," Baumann said. "In firefighters specifically, the stress has been linked to increased risk of alcohol abuse, cardiovascular disease, and posttraumatic stress disorder. Finding a way to reduce the stress levels is a worthy goal."

MU studies link depression and breast cancer outcomes
2011-11-03
COLUMBIA, Mo. – This year, more than 230,000 women will be diagnosed with breast cancer and nearly 40,000 women will not survive their battle with cancer, according to the American Cancer Society. New research from the University of Missouri shows that certain factors, including marital status, having children in the home, income level and age, affect the likelihood of depression in breast cancer survivors. Further, depressed patients are less likely to adhere to medication regimens, potentially complicating the progress of their treatment.

Watching the birth of an iceberg
2011-11-03
PUNTA ARENAS, CHILE – After discovering an emerging crack that cuts across the floating ice shelf of Pine Island Glacier in Antarctica, NASA's Operation IceBridge has flown a follow-up mission and made the first-ever detailed airborne measurements of a major iceberg calving in progress.
NASA's Operation Ice Bridge, the largest airborne survey of Earth's polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an unprecedented three-dimensional view of Arctic and Antarctic ice sheets, ice shelves and sea ...
Study shows new medication effectively treats underlying cause of cystic fibrosis
2011-11-03
SEATTLE -- A new study has confirmed that the drug, ivacaftor (VX-770), significantly improves lung function in some people with cystic fibrosis (CF). The results of the phase III clinical trial study, "A CFTR Potentiator in Patients with Cystic Fibrosis and the G551D Mutation," led by Bonnie W. Ramsey, MD of Seattle Children's Research Institute and the University of Washington, were published today in the New England Journal of Medicine.
Ivacaftor, also known as VX-770, was developed by Vertex Pharmaceuticals with financial support from the Cystic Fibrosis Foundation. ...
Scientists prevent cerebral palsy-like brain damage in mice
2011-11-03
Scientists at Washington University School of Medicine in St. Louis have shown that a protein may help prevent the kind of brain damage that occurs in babies with cerebral palsy.
Using a mouse model that mimics the devastating condition in newborns, the researchers found that high levels of the protective protein, Nmnat1, substantially reduce damage that develops when the brain is deprived of oxygen and blood flow. The finding offers a potential new strategy for treating cerebral palsy as well as strokes, and perhaps Alzheimer's, Parkinson's and other

TRMM Satellite sees Tropical Storm Keila form in the Arabian Sea
2011-11-03
The TRMM satellite passed directly above a recently formed tropical cyclone in the Arabian Sea on November 2, 2011 at 0350 UTC (11:50 p.m. EDT, Nov. 1). An analysis of rainfall was done using TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments. TRMM data showed that rainfall rates with tropical storm Keila ranged from light to moderate along the south-eastern coast of Oman. Moderate to heavy rainfall was revealed to be spiraling into Keila's center of circulation in the Arabian Sea near the southeastern coast of Oman.
TRMM Precipitation Radar data was ...
Nicotine primes brain for cocaine use: Molecular basis of gateway sequence of drug use
2011-11-03
Cigarettes and alcohol serve as gateway drugs, which people use before progressing to the use of marijuana and then to cocaine and other illicit substances; this progression is called the "gateway sequence" of drug use. An article in Science Translational Medicine by Amir Levine, MD, Denise Kandel, PhD; Eric Kandel, MD; and colleagues at Columbia University Medical Center provides the first molecular explanation for the gateway sequence. They show that nicotine causes specific changes in the brain that make it more vulnerable to cocaine addiction -- a discovery made by ...

Reprogramming stem cells to a more basic form results in more effective transplant, study shows
2011-11-03
Durham, NC November 2011 Chinese stem cell scientists have published new research that improves the survival and effectiveness of transplanted stem cells. The research led by Dr Hsiao Chang Chan, from the Chinese University of Hong Kong, is published in Stem Cells.
Research into differentiation has led to a variety of breakthroughs as stem cell researchers harvest cells from one part of the body and genetically adapt them to fulfill a specialized role. However, if the implanted cells are too much like the cells of the targeted area they may not have the plasticity to ...
Low vitamin D common in spine surgery patients
2011-11-03
A new study indicates that many patients undergoing spine surgery have low levels of vitamin D, which may delay their recovery.
In a study of 313 patients undergoing spinal fusion surgery, orthopaedic surgeons at Washington University School of Medicine in St. Louis found that more than half had inadequate levels of vitamin D, including one-fourth who were more severely deficient.
The researchers report their findings today at the 26th Annual Meeting of the North American Spine Society. The study was chosen as one of the meeting's best papers.
"Our findings suggest ...
