Researchers said on Wednesday they had found a new gene called New Delhi metallo-beta-lactamase, or NDM-1, in patients in South Asia and in Britain.

U.S. health officials said on Wednesday there had been three cases so far in the United States -- all from patients who received recent medical care in India, a country where people often travel in search of affordable healthcare.

NDM-1 makes bacteria highly resistant to almost all antibiotics, including the most powerful class called carbapenems. Experts say there are no new drugs on the horizon to tackle it.

"It's a specific mechanism. A gene that confers a type of resistance (to antibiotics)," Dr. Alexander Kallen of the U.S. Centers for Disease Control and Prevention in Atlanta said in a telephone interview.

With more people traveling to find less cost ... Read more »

More than one in 10 scientists claim to have been pressurised by a commercial financial backer to "tailor" their research conclusions, according to a new survey. It paints a gloomy picture of a highly skilled, professional sector which feels demoralised and undervalued by the public.

It reveals that pay has emerged as an important issue, while many are tempted to quit because of worries about funding and lack of career progression.

The survey was carried out by the Association of University Teachers and Prospect - unions representing staff working in the higher education sector, government, the NHS and charitable trusts - which claimed its findings represented "an alternative skills strategy" to a long-awaited government white paper on skills published yesterday.

Many of the proposals in the white paper are based on those in a paper published two years ago. But in a move which recognises the need for "higher level" tec ... Read more »

TUESDAY, Aug. 10 (HealthDay News) -- Women's cholesterol levels vary throughout their menstrual cycle as their levels of estrogen rise and fall, a new study reveals.

This means that to get a clear picture of a woman's cholesterol levels, doctors may need to take readings over several months before deciding whether the patient needs to have her levels lowered, the researchers noted.

"Doctors who are looking at women [for] high cholesterol have to take into account the phase of the menstrual cycle they are at when they take the measurement," said study co-author Enrique F. Schisterman, chief of the Epidemiology Branch at the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

To make cholesterol readings more consistent and reliable, measurements should be taken at the same time each month for a couple of cycles, Schisterman added.

WEDNESDAY, Aug. 11 (HealthDay News) -- A natural mechanism that may help prevent the development of AIDS in sooty mangabey monkeys has been discovered by scientists.

Sooty mangabey monkeys are a natural host for the simian immunodeficiency virus (SIV), but they don't develop AIDS even if they have a very high viral load. SIV -- a virus that infects monkeys -- is related to the human immunodeficiency virus (HIV) in people.

These monkeys may be able to avoid developing AI ... Read more »
