Bedbugs with 'superbug' germ found

ATLANTA: Hate insects? Afraid of germs? Researchers are reporting an alarming combination: bedbugs carrying a staph "superbug." Canadian scientists detected drug-resistant staph bacteria in bedbugs from three hospital patients from a downtrodden Vancouver neighborhood.

Bedbugs have not been known to spread disease, and there's no clear evidence that the five bedbugs found on the patients or their belongings had spread the MRSA germ they were carrying or a second less dangerous drug-resistant bacteria.

However, bedbugs can cause itching that can lead to excessive scratching. That can cause breaks in the skin that make people more susceptible to these germs, noted Dr. Marc Romney, one of the study's authors.

The study is small and very preliminary. "But it's an intriguing finding" that needs to be further researched, said Romney, medical microbiologist at St. Paul's Hospital in Vancouver.

The hospital is the closest one to the poor Downtown Eastside neighborhood near the city's waterfront. Romney said he and his colleagues did the research after seeing a simultaneous boom in bedbugs and MRSA cases from the neighborhood.

Five bedbugs were crushed and analyzed. MRSA, or methicillin-resistant Staphylococcus aureus, was found on three bugs. MRSA is resistant to several types of common antibiotics and can become deadly if it gets through the skin and into the bloodstream.

Two bugs had VRE, or vancomycin-resistant Enterococcus faecium, a less dangerous form of antibiotic-resistant bacteria.

Both germs are often seen in hospitals, and experts have been far more worried about nurses and other health care workers spreading the bacteria than insects.

It's not clear if the bacteria originated with the bedbugs or if the bugs picked it up from already infected people, Romney added.

The study was released Wednesday by Emerging Infectious Diseases, a publication of the U.S. Centers for Disease Control and Prevention. (AP)

People with diabetes more likely to get cancer

NEW YORK: People with diabetes are at higher risk for certain cancers than those without the blood sugar disease, suggests a new study.

Based on data from a telephone survey of nearly 400,000 adults, researchers found 16 out of every 100 diabetic men and 17 out of every 100 diabetic women said they had cancer.

That compares to just seven per 100 men and 10 per 100 women without diabetes.

"The significant association between cancer and diabetes does not surprise us," said Dr. Chaoyang Li, an epidemiologist at the Centers for Disease Control and Prevention in Atlanta, Georgia, whose findings appear in the journal Diabetes Care.

According to the CDC, nine percent of U.S. adults have diabetes.

After taking into account things like age, race, smoking and drinking habits, the researchers concluded that diabetic men and women were 10 percent more likely to have had a cancer diagnosis of any kind.

Li told Reuters Health other studies have also found a link between the two diseases, although there is no proof that one causes the other.

The researchers found that the types of cancers that were more likely among diabetics differed between men and women.

Compared to people without diabetes, diabetic men were more likely to report having colon, pancreas, rectum, urinary bladder, kidney or prostate cancer (the latter only occurs in men). Diabetic women had more cases of breast cancer, leukemia or cancer of the womb.

For men, the greatest increase in risk was for pancreatic cancer, with 16 per 10,000 cases among diabetics and just two per 10,000 among non-diabetics.

That corresponds to a four-fold difference after taking other factors into account.

Women's risk of leukemia also varied greatly between the two groups. One per 1,000 women without diabetes said they had been diagnosed with the blood cancer, compared to three per 1,000 women with diabetes.

This new study is just a snapshot of people's medical history, and does not follow them over time.

Dr. Fred Brancati, a professor at Johns Hopkins University in Baltimore, said he was struck by the findings, because some of the cancers kill people fast, meaning they wouldn't show up in the study.

"It shows there's a substantial pool of American adults who have diabetes and cancer," said Brancati, who was not involved in the study. "The authors rightly point out that these two conditions go together beyond chance alone, so it pays to think about them together."

Brancati's own research has shown that the risk of death from cancer among people with diabetes is about 40 percent higher than among non-diabetics (see Reuters Health report, December 16, 2008).

Li said it's still unclear why diabetes is tied to cancer. High blood sugar levels or excess blood insulin -- a hormone that helps ferry sugar into the cells -- might increase the risk, but that has not been proven.

Certain lifestyle choices reduce the risk of both diabetes and cancer, such as maintaining a healthy weight and not smoking.

Li said the findings are an important reminder for people with diabetes and their doctors to meet regular cancer screening guidelines and to discuss any possible cancer risk from anti-diabetic therapy. (Reuters)
