New breast cancer drug shows promise

A newer drug clearly outperforms tamoxifen at preventing breast cancer from returning and should become the first-choice treatment for most women who have had the disease, doctors are reporting.

The drug, Arimidex, might be able to prevent 70 percent to 80 percent of the most common type of tumors that occur in women after menopause, compared with the 50 percent that tamoxifen is credited with warding off, their research suggests.

SARS vaccine 'passes first hurdle'

Chinese researchers have developed a SARS vaccine that has passed the first stage of human trials, state media has reported, raising hopes for the prevention of a virus that killed some 800 people since it emerged in 2002.

Antibodies against Severe Acute Respiratory Syndrome (SARS) developed in 24 of 36 volunteers in the trial, the official Xinhua news agency said Monday, though several more clinical trials were required before the vaccine would be ready for commercial use.

Poor diet linked to bad behaviour

Children who have a poor diet are more likely to become aggressive and anti-social, US researchers believe. The University of Southern California found a lack of zinc, iron, vitamin B and protein in the first three years caused bad behaviour later on. At eight years old, children fed poorly were more likely to be irritable and pick fights than those fed healthily. Aged 11, they swore, cheated and got into fights, and at 17, they stole, bullied others and took drugs. The researchers analysed the development of more than 1,000 children on Mauritius, an island in the Indian Ocean off the coast of Africa, over 14 years. They found the more malnurished the children were, the greater the anti-social behaviour later on.

Smoke inhalation

Many news stories covering a fire often end with a line such as "12 people were treated for smoke inhalation."

The implication is that their injuries weren't very serious, but, in fact, smoke inhalation can be very tricky to treat and kills more people after a fire than burns do.

When a fire burns, it releases searing hot gases and, especially if plastics or synthetic fabrics are burning, hundreds of toxic chemicals. The chemicals can damage the delicate tissues in the lungs where the exchange of oxygen and carbon dioxide takes place.

Carbohydrates may be considered evil in this age of the low-carb diet revolution, but the nutrient plays an important role in helping athletes recover from strenuous exercise.

Two decades of research have shown that consuming carbs after a hard workout rebuilds worn muscles and primes the body for the next training. Failure to eat the right food after exercise -- or worse -- skipping the post-exercise meal altogether can harm your body.

Some previous studies have suggested that men who have frequent ejaculations -- whether through sex or masturbation -- might be more prone to prostate cancer. One theory is that lots of sex exposes men to various germs and viruses that somehow lead to prostate cancer.

Drug could block Sars infection

A body chemical that could wipe out the virus that causes Sars may have been found by researchers.
In theory, a drug based on the antibody could be available long before a vaccine could be produced.

Antibodies are created by the body's immune system to launch attacks on foreign invaders such as bacteria.

Experts from a Boston cancer institute looked through a "library" of human antibodies before they found one which worked against Sars virus.

High Estrogen Levels Stress You Out

High levels of estrogen seem to make the brain more vulnerable to stress, says new research from Yale University.
That finding may explain why stress-related disorders such as depression occur twice as often in women as in men, the study authors suggest.

The area of the brain called the prefrontal cortex is sensitive to stress. Studies have found cognitive functioning of that part of the brain becomes impaired under uncontrollable stress. What researchers don't know is what role estrogen might play in impairing prefrontal cortex function.

Study examines cancer risk from hair dye

Women who have been coloring their hair for 24 years or more have a higher risk of developing a cancer called non-Hodgkin lymphoma, researchers reported.
They said their study of 1,300 women could help explain a mysterious rise in the number of cases of the cancer that affects the lymphatic system.

Writing in the American Journal of Epidemiology, they said women who dyed their hair starting before 1980 were one-third more likely to develop non-Hodgkin lymphoma, or NHL, and those who used the darkest dyes for more than 25 years were twice as likely to develop the cancer.

Report: Teen depression may shrink part of brain

Teenagers with depression may have abnormal brain structure, Canadian researchers say in a new report.

Imaging studies show that adolescents with major depression tend to have a small hippocampus. This is a part of the brain associated with motivation, emotion and memory formation.

The study, done by a team at Dalhousie University in Nova Scotia and the National Research Council of Canada, fits in with others that suggest depression can shrink the hippocampus.

Major stress and trauma -- both depression triggers -- can also cause the shrinkage.

Worst of the flu over?

An especially virulent strain of the flu virus is sickening people across the United States with several states reporting widespread outbreaks. But federal health officials recently said this year's influenza activity appears to be on the downturn. "We are cautiously optimistic that at least in some parts of the country, influenza may have peaked," said Dr. Julie Gerberding, director of the Centers for Disease Control and Prevention. "But there's still plenty of flu out there." As many as 36,000 people in the United States die each year of what's commonly known as the flu, according to the CDC.

In Bangkok, Thailand's health minister confirmed two children have bird flu, which has killed five Vietnamese - including a 5-year-old girl -- in the past two weeks.

Smaller chains Hardee's and Carl's Jr. dumped the bread from some hamburgers last month, going lettuce-wrapped instead, and TGI Friday's restaurant has started serving a bunless cheeseburger, too.

Overweight adults who are not on a diet need only a small amount of exercise -- the equivalent of a half-hour of brisk walking per day -- to prevent further weight gain, a study found.

Participants who got no exercise during the eight-month study gained an average of almost 2.5 pounds. But 73 percent of those who briskly walked 11 miles a week, or about 30 minutes a day, were able to maintain their weight or even lose a few pounds.

A Shot of Hope - A vaccine for cancer

A vaccine for cancer seems almost too good to be true. But recent developments in scientists' understanding of both genetics and the immune system are making cancer vaccines a reality.

Vaccines for cancer, including a vaccine designed to treat a type of non-Hodgkin's lymphoma, or NHL, are now being studied in national clinical trials.

The NHL vaccine is a type of immunotherapy, meaning that it uses the body's own immune system to treat the cancer. But unlike traditional vaccines for infectious diseases, this vaccine is customized to each patient using molecules from an individual patients' tumor.

Under the Skin - Psoriasis

It turns out that psoriasis, a chronic skin condition that causes itchy, scaly red patches, is more than skin deep. Over the last decade, researchers discovered that psoriasis is due to a problem not with the skin but with the immune system — and a recent study has linked the condition to lymphoma, which is a cancer of the immune system.

The study, published in the November 2003 issue of the Archives of Dermatology, found that the rate of lymphoma in people with psoriasis was almost three times higher than the rate in people without the skin condition. But it's yet not clear what caused the increase in lymphomas.

"If you look at that little vial, it's mysterious — people don't know what's in there," he says. "We're trying to make it less frightening."
What should scare parents more than getting vaccines for their children, Offit says, are the consequences of not getting them — increased risk of potentially deadly diseases such as meningitis, chicken pox and whooping cough.

The review is looking at data on many of the top-selling psychiatric drugs, including Paxil, Prozac and Celexa. None of the drugs is licensed for use in children, but doctors often do still prescribe them.
Word of the review follows two Health Canada warnings. In July, the agency cautioned that children and teens taking Paxil could be at a higher risk for suicidal thoughts. In September, it issued a similar warning about Effexor.
