A Colombian woman has received the world's first tailor-made trachea transplant, grown by seeding a donor organ with her own stem cells to prevent her body rejecting it, an international research team reported on Wednesday.
A committee of scientists set up by the US Department of Veterans Affairs has reported that nearly a third of veterans of the Gulf war of 1990-1991 - some 200,000 people - continue to suffer from a Gulf war syndrome caused by exposure to organophosphate nerve gas, nerve gas remedies and insecticides.
"Gulf War illness is real," the report concludes. "Few veterans have recovered." Their last report in 2004 also concluded that GWS is not psychological but caused by organophosphates.
Research since then, they report, has strengthened the association, and shows it may involve inflammatory chemicals called cytokines in the brain.

Washington - Primary care doctors in the United States feel overworked and nearly half plan to either cut back on how many patients they see or quit medicine entirely, according to a survey released on Tuesday.
And 60 percent of 12,000 general practice physicians found they would not recommend medicine as a career.
"The whole thing has spun out of control. I plan to retire early even though I still love seeing patients. The process has just become too burdensome," the Physicians' Foundation, which conducted the survey, quoted one of the doctors as saying.
The survey adds to building evidence that not enough internal medicine or family practice doctors are trained or practicing in the United States, although there are plenty of specialist physicians.

Genetically modified corn has been linked to a threat to fertility in an official study that could deliver a hammer blow to controversial 'Frankenstein Food'.
A long-term feeding trial commissioned by the Austrian government found mice fed on GM corn or maize had fewer offspring and lower birth rates.
The trial has triggered a call from Greenpeace for a recall of all GM food crops currently on the market worldwide on the grounds of the threat to human health.
High magnesium intake has been associated with low risk of colorectal cancer. Americans have similar average magnesium intake as East Asian populations. If that were all that were involved, observers might expect both groups to have similar risk for colorectal cancer.
However, the United States has seen a much higher colorectal cancer incidence rate than East Asian populations. Furthermore, when East Asians immigrated to the United States, their incidence rates for colorectal cancer increased. This led researchers at Vanderbilt University to suspect there was something else at work.
Calcium supplementation has been shown to inhibit colorectal carcinogenesis although high calcium may simultaneously be preventing the body from absorbing magnesium. United States patients have a higher calcium intake and higher colorectal cancer incidence. "If calcium levels were involved alone, you'd expect the opposite direction. There may be something about these two factors combined - the ratio of one to the other - that might be at play", said Qi Dai, M.D., Ph.D., assistant professor of medicine at Vanderbilt University.

London - A dangerous, drug-resistant bacterium normally found in soil and water is on the increase in hospitals worldwide, an infectious disease expert warned on Tuesday.
Acinetobacter baumannii is more resistant than the MRSA superbug and accounts for about 30 percent of drug-resistant hospital infections, said Matthew Falagas, director of the Alfa Institute of Biomedical Sciences in Greece.

SANTIAGO, Chile - Copper socks? Copper towels? How about copper subway poles? These are only a few of the uses Chile, the world's biggest copper producer, is applying to the red metal now used more in the construction and auto sectors.
Geneva -- Tuberculosis is mutating into dangerous, drug-resistant forms for which no cure is known, health leaders in Switzerland said.
One strain of XDR-TB, which stands for extensively drug-resistant tuberculosis, doesn't respond to antibiotics normally used to treat TB, making it virtually incurable and threatening to become a pandemic, CNN reported Monday.
The World Health Organization estimated about 40,000 new cases of XDR-TB emerge annually.
Health experts said XDR-TB shouldn't exist because TB is curable, CNN reported. But if anti-TB drugs aren't correctly administered or used, the disease can mutate into deadlier strands.

HUNTINGTON - As a portly woman plodded ahead of him on the sidewalk, the obese mayor of America's fattest and unhealthiest city explained why health is not a big local issue.
Just as an outbreak of one type of gastrointestinal illness in Dane County seems to be declining, another is on the rise - among University of Wisconsin students.
More than 100 students have been reported ill the past week with vomiting and diarrhea in an outbreak thought to be caused by norovirus, Dr. Sarah Van Orman, executive director of University Health Services, said Friday.
At least 63 of the cases are students living in Sellery Hall, where crews have been cleaning the bathrooms at least seven times a day to stop the spread of the illness, Van Orman said. Most of the other cases have been in fraternity and sorority houses, with a few among students in off-campus housing.
