Recent studies confirm significant underuse of colorectal cancer screening
Two recently released studies confirm an alarming reality, that a majority of Americans who should be getting screened for colorectal cancer are not. According to a study in the journal Cancer, among an assessment of Medicare beneficiaries between 1998 and 2004, only 25.4 percent of people were screened, despite Medicare coverage for colorectal cancer screening. Figures released by the Agency for Healthcare Research and Quality show that only half of Americans age 50 and over have had a screening colonoscopy. -
06:00Detecting pollution, like catching criminals, requires evidence and witnesses; but on the scale of countries, continents and oceans, having enough detectors is easier said than done. A team of air quality modelers, climatologists and air policy specialists at Arizona State University may soon change that. Under a grant from the Environmental Protection Agency, they have developed a new way to close the gaps in the global pollution dragnet by using NASA satellite data to detect precursors to ozone pollution.

06:00Researchers at Sarasota Memorial Health Care System today announced the start of the EASE trial, an international, multi-center clinical trial to explore an investigational treatment that may offer a significant new, minimally-invasive option for those suffering with advanced widespread emphysema. The study focuses on a procedure called airway bypass that involves creating pathways in the lung for trapped air to escape and in turn, relieve emphysema symptoms including shortness of breath.

06:00Five years post-conflict, individuals who served in the 1990-1991 Persian Gulf War were 25 percent more likely to visit an emergency department than veterans of the same era who were not deployed, but were no more likely to have a hospital stay or an outpatient visit, according to a study in December 2007 issue of American Journal of Public Health.

06:00Noncombat-related acute and recurrent chronic pain are the leading causes of soldier attrition in modern war, with the return-to-duty rate as low as 2 percent when these soldiers are treated outside the theaters of operation. However, that rate jumps to 95 percent when troops and officers are treated and managed for pain in the field of instead of being sent elsewhere for therapy, according to a new study from a Johns Hopkins anesthesiologist.

06:00Poultry workers in the United States are 32 times more likely to carry E. coli bacteria resistant to the commonly used antibiotic, gentamicin, than others outside the poultry industry, according to a recent study conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. This is the first US research to show exposure occurring at a high level among industrial poultry workers.

06:00MIT scientists have found a way to induce cells to form parallel tube-like structures that could one day serve as tiny engineered blood vessels.
-
06:00A Northwestern University study reports that a mutation in a transcription factor that controls a neurotransmitter in the nematode C. elegans causes an imbalance in neuronal signaling that results in protein damage in target cells. Similar results and consequences on protein folding were found to occur upon exposure to the common toxins nicotine and lindane (a pesticide). Neurons become overexcited and fire incorrect signals too rapidly, resulting in proteins in target muscle cells becoming stressed, misfolding and becoming nonfunctional.
-
06:00Each year, 40 to 60 percent of American adults suffer from chronic back pain. More than one million spine surgery procedures are performed annually, with medical costs to treat back pain approaching $24 billion per year.

06:00OHSU researchers have uncovered the system that tells the body when to perform one of its most basic defenses against the cold: shivering. The scientists have discovered the brain's wiring system, which takes temperature information from the skin and determines when a person should start shivering. Their findings are published in the advance online edition of the journal Nature Neuroscience.

06:00OHSU researchers have uncovered new information about the body's immune system in a study that suggests new strategies may be in order for protecting the country's aging population against disease. The scientists discovered an actual process by which naïve T cells are lost later in life.

06:00Homeowners dogged by household fleas need look no farther than the broom closet to solve their problem. Scientists have determined that vacuuming kills fleas in all stages of their lives, with an average of 96 percent success in adult fleas and 100 percent destruction of younger fleas. In fact, the results were so surprisingly definitive that the lead scientist, an Ohio State University insect specialist, repeated the experiments several times to be sure the findings were correct.

06:00Successful reproduction is critical to pass genes to the next generation. In sexually reproducing organisms, sperm enter the female with seminal proteins that are vital for fertility. In a new study published on Friday, Dec. 14, 2007 in PLoS Genetics, researchers at Cornell University knocked down the levels of 25 seminal proteins individually in male fruit flies, testing the males' abilities to modulate egg production, sperm storage and release, and the females' post-mating behavior and physiology.

06:00Two observational studies have documented that adults with ADHD, when compared to a control group, were more likely to use certain illicit drugs, engage in certain antisocial behaviors, have financial problems and engage in risky sexual behavior. The studies, conducted at the University of Massachusetts and at the Medical College of Wisconsin appear in a new book, "ADHD in Adults: What the Science Says," by Russell Barkley, Ph.D.

06:00A novel surgical technique allowing doctors to operate on patients by making a Z-shaped incision inside the stomach could potentially replace certain types of conventional surgery in humans, according to Penn State medical researchers who have successfully demonstrated the procedure in pigs.
-
06:00A new biochip technology could eliminate animal testing in the chemicals and cosmetics industries, and drastically curtail its use in the development of new pharmaceuticals, according to new findings from a team of researchers at Rensselaer Polytechnic Institute, the University of California at Berkeley, and Solidus Biosciences Inc.
-
06:00Using the latest nanofabrication methods, a team of Rice University physicists has discovered a surprising new electronic property in one of the earliest-known and most-studied magnetic minerals on Earth -- lodestone. Also known as magnetite, lodestone was used to make compass needles as early as 900 years ago. In new research in Nature Materials, the researchers describe how super-cooled magnetite reverted from an insulator to a conductor when the voltage was altered in their experiment.

06:00When Javier Rodriguez Molina visited the Atocha Train Station Memorial in Madrid last summer, the Barcelona native felt a great sadness for the victims of the March 11, 2004, Madrid train bombings. But he also felt some hope that his advanced emergency technology work at University of California-San Diego can some day save lives in similar disasters.
-
06:00The ability of Argentine ants to change from carnivorous insect eaters to plant sap-loving creatures has helped these invasive social insects rapidly spread throughout coastal California, according to a new study, displacing many native insects and creating ant infestations familiar to most coastal residents.
-
06:00Acute and chronic constipation together accounted for nearly half of all cases of acute abdominal pain in children treated at one hospital. The study also suggests that physicians should do a simple rectal examination for constipation when trying to determine the cause of abdominal pain in children.
