| Most Australians may refuse H1N1 vaccine SYDNEY (UPI) -- Sixty-five percent of people in Australia say they are unlikely to get vaccinated against H1N1 in the next 12 months, a survey indicates.
An MBF Healthwatch Poll says, in terms of people at higher risk, 33 percent with asthma or lung disease, 45 percent with diabetes, 28 percent with reduced immunity and 40 percent with heart disease had been vaccinated.
Seventy-one percent of those planning to travel to the northern hemisphere over the summer holidays -- flu season in the northern hemisphere -- say thy were not intending to get vaccinated against H1N1.
The most common reasons given for being reluctant to get vaccinated are:
-- 48 percent say it is unnecessary.
-- 41 percent say health experts are giving mixed messages.
-- 38 percent say the threat in Australia has passed.
-- 38 percent say they are not at risk of getting H1N1.
-- 39 percent say they have concerns about the safety or possible side effects from the vaccine.
"While the number of new cases of swine flu in Australia might have waned since last winter, the disease is still a major threat," Dr. Christine Bennett, chief medical officer of Bupa Australia, says in a statement.
The survey of 1,200 age 16 and older was conducted by NewsPoll on the weekend of Dec. 12-13.

| Lawsuit fear linked to more antibiotic use NEW YORK (UPI) -- Liability concerns may play a role in the proliferation of "superbugs" in hospitals by encouraging doctors to prescribe more antibiotics, U.S. researchers say.
A team of researchers at New York Medical College analyzed census figures, statistics on population density of attorneys and physicians, and data on antibiotic utilization for the United States, Canada and 15 European countries.
Lead author Dr. George Sakoulas said the study found a strong correlation between the prevalence of methicillin resistance and density of attorneys in countries in Europe and North America. They found no correlation between prevalence of methicillin resistance and physician density.
Investigators surveyed 162 healthcare providers to determine whether medical liability concerns were as important as antibiotic cost and formulary restrictions in selecting treatment regimens.
The study, published in the American Journal of Therapeutics, confirmed physicians were more concerned about medical liability in cases of under-prescribing antibiotics than by over-prescribing, Sakoulas said.
"The findings suggest that more research is needed to evaluate the potential impact of medical liability concerns on the medical care system," Sakoulas said in a statement. "The study findings hint toward the importance of medical tort reform as a way to reduce healthcare costs and improve quality. Another way might be to foster more judicious prescription of antibiotics based on science and evidence."

| Chemo drugs disrupt new brain cells ROCHESTER, N.Y. (UPI) -- U.S. researchers say animal models show chemotherapy drugs may disrupt brain cell growth.
Researchers at the University of Rochester Medical Center suggest this disruption might be reversed through the use of insulin-like growth factor -- a hormone in the body that is key to the functioning of several metabolic pathways that construct molecules from smaller units.
The disruption to cognitive function associated with some chemotherapy drugs -- known as chemo brain -- has become a newly recognized condition, the researchers say.
Signs of chemo brain reported by cancer patients include memory lapses, problems concentrating, confusion, difficulty multitasking and slow thinking in the weeks, months or even years after chemotherapy ends.
"It is not yet clear how our results can be generally applied to humans but we have taken a very significant step toward reproducing a debilitating condition and finding ways to treat it," principal investigator Dr. Robert Gross says in a statement.
The study is published online in the journal Cancer Investigation.

| Melanoma rates vary by race, ethnicity MIAMI (UPI) -- Both the frequency and seriousness of melanoma vary by race and ethic group, University of Miami researchers found.
Dr. Shasa Hu and colleagues at the Sylvester Comprehensive Cancer Center at the University's Miller School of Medicine and colleagues found Caucasian and Hispanic people were diagnosed with melanoma more frequently in recent years -- the rate going up by 3 percent or more per year from 1990-2004 for white men, white women and Hispanic women.
However, Hispanic and African-American patients continue to have advanced skin cancer at diagnosis.
The report, published in the Archives of Dermatology, found 18 percent of white Hispanic patients and 26 percent of black patients had disease that had spread -- vs. 12 percent of white non-Hispanic patients.
"Improved secondary prevention measures with earlier detection of thin -- early-stage -- melanoma likely account for the improved survival among whites from 68 percent in the early 1970s to 92 percent in recent years. However, such advances have not occurred in other racial and ethnic groups in the United States," the study authors said in a statement.
Hu analyzed data extracted from the state cancer registry. Of 41,072 cases of melanoma diagnosed from 1990-2004, 39,670 were diagnosed in white non-Hispanic individuals, 1,148 in white Hispanics and 254 in blacks.
