More Than a Quarter of Melanoma Survivors Skip Sunscreen, Study Finds

And 2 percent continue to use tanning beds, researchers reportAnd 2 percent continue to use tanning beds,

MONDAY, April 8 (HealthDay News) -- Even people who have survived melanoma, the deadliest form of skin cancer, often fail to protect themselves from the sun, a new study suggests.

Researchers found that of 171 melanoma survivors in a U.S. survey, more than 25 percent said they never used sunscreen when spending more than an hour outside on a sunny day. What's more, 2 percent said they had used tanning beds in the past year.

"They did do a better job of protecting themselves than the average person," said lead researcher Dr. Anees Chagpar, an associate professor of surgery at Yale University's School of Medicine. "But there is room for improvement," she added.

"Maybe we need to be more vigilant about education," said Chagpar, who was to present the findings Monday at the American Association for Cancer Research annual meeting, in Washington, D.C.

The results are based on a 2010 government health survey that included 27,120 U.S. adults, 171 of whom reported a history of melanoma.

Melanoma is the least common form of skin cancer, accounting for less than 5 percent of skin cancers in the United States, according to the American Cancer Society. Still, most deaths from skin cancer are due to melanoma -- which often spreads to other parts of the body if it's not caught early.

Because too much ultraviolet (UV) light is a major melanoma risk factor, experts advise everyone to limit their exposure. That means staying in the shade, donning sunscreen and covering up when you're in the sun, and avoiding the tanning salon altogether.

You would expect that if anyone would follow that advice, it would be melanoma survivors, Chagpar said.

And some did, her team found. On days when they were going to be in the sun for more than an hour, one-third of melanoma survivors "always" wore sunscreen, versus 17 percent of other Americans. They were also more likely to always wear a cap (31 percent did) or a long-sleeved shirt (12 percent).

On the other hand, 27 percent of melanoma survivors said they never slathered on sunscreen before spending more than an hour in the sun.

"We were very surprised by that," Chagpar said. What "blew her mind," though, was the fact that 2 percent of melanoma survivors visited tanning beds.

She noted that other researchers are studying the possibility that tanning is addictive for some people. It's possible, Chagpar speculated, that even some melanoma survivors may be hooked on the experience.

A dermatologist not involved in the study agreed that some of the findings are troubling. "It is certainly concerning that a quarter of the melanoma survivors never wear sunscreen," said Dr. Hensin Tsao, a melanoma expert at Massachusetts General Hospital in Boston.

New Bird Flu No Immediate Threat: U.S. Experts

There's been no clear evidence of human-to-human transmission in Chinese outbreakThere's been no clear evidence of human-to-human

By Amanda Gardner

TUESDAY, April 9 (HealthDay News) -- At this point, there's no reason to believe that the emerging H7N9 strain of bird flu that has sickened at least 24 people and killed seven in China is cause for alarm, health officials in the United States say.

For one thing, no cases of human-to-human transmission of the virus have yet been reported -- a necessary precursor to a full-blown pandemic.

"This is very early in the course of identification of human cases," said Dr. John Midturi, assistant professor of internal medicine at the Texas A&M Health Science Center College of Medicine, in Temple.

"We do see something similar every few years with avian [bird] flu," added Richard Webby, a member of the department of infectious diseases at St. Jude's Children's Research Hospital in Memphis.

But this year's strain does seem a little different.

"What's making everyone a little bit more uneasy is that, looking at the sequence of the virus, it appears to have some mutations we think may indicate that the virus might have increased its ability to replicate in humans," Webby said.

But for now, there's no proof of that ability, he cautioned, and the genetic sequence of the virus would still need to change for it to pass easily from person to person.

The first human cases were not identified until March 31, according to published reports.

It's possible that the H7N9 virus is also found in some type of mammal, such as swine, and public-health officials are working to identify possible hosts.

"We don't think that necessarily just this virus growing in [birds] would cause some of these [genetic] changes," said Webby, who's also director of the World Health Organization Collaborating Center for Studies on the Ecology of Influenza Viruses in Lower Animals and Birds. "We can't say with any sort of gusto that the last host of this virus was an avian host. Avian flu is a very generic sort of term.

Chinese authorities are taking precautions against further spread of the virus, suspending sales of live poultry in Shanghai and slaughtering poultry in markets where the virus has been detected.

On Monday, the World Health Organization announced that it was in talks with the Chinese government about sending experts to help investigate the outbreak.

The good news is that most of the human cases "have been associated with poultry exposure, which is typical with most bird flu outbreaks," Midturi said.

However, the flu strain has also been found in live pigeons being sold as poultry at a market in Shanghai. That has unnerved some experts since any infection among wild pigeons would be tougher to control than among penned-in poultry.

The fatality rate from H7N9 also remains unclear. Although the death rate in China seems high, with six deaths out of 16 confirmed cases, authorities don't know at this point how many people have actually been infected. If hundreds or thousands of people contracted the virus with few or no symptoms, the true fatality rate would be much lower, said Midturi, who is also director of infectious disease at Scott & White Memorial Hospital in Temple.

Losing 1 stone

Before starting my diet/fitness plan I weighed 141lbs. I have since lost 4lbs but aim to get back to my previous weight of 126lbs so still have 11lbs to lose. I have been following 1200 net kcals per day (without cutting out carbs etc) and doing 1 hour gym sessions 4 times a week. However, the past week I have lost no weight and the majority of my weight loss was in the first week. The lack of weight loss recently when working so hard is really demotivating. 

I am looking for anyone who has experiences of losing weight at a similar size to myself and any tips or diets that have worked for you! Has anyone tried low carb diets and would these help give me a boost?

Thanks :)

Unemployment's Toll Can Be Heartbreaking

Resulting stress, anxiety, bad habits may lead to cardiovascular troubleResulting stress, anxiety, bad habits may lead to

By Serena Gordon

HealthDay Reporter

THURSDAY, April 11 (HealthDay News) -- As anyone who's lost a job can attest, stress and worry often quickly follow. But the health of your heart after unemployment can also take a tumble.

Job loss can cause immediate heart issues, and the stress and bad habits that frequently come with unemployment can build up over time, causing cardiovascular damage, health experts say.

In some people, especially those who might not be expecting the job loss or those with significant financial obligations, getting fired may cause a condition called broken heart syndrome. "In a very stressful situation, you can actually get a severe release of adrenaline and sympathetic nerve discharges that cause the heart to beat irregularly," said Dr. John Higgins, a sports cardiologist at the University of Texas Health Science Center in Houston.

These changes can actually cause a heart attack in some people, though Higgins said that most people who have significant stress reactions return to normal over time without having a heart attack.

Long-term changes that happen after a job loss -- such as financial stress, family problems, loss of daily routine and sometimes higher-risk behaviors, like increased alcohol use or a poor diet -- can cause heart problems to develop over time, Higgins explained.

Psychological factors can play a role, too.

"Most of us know the common risk factors for heart disease, like high cholesterol, high blood pressure and genetics, but about 25 to 35 percent of heart disease remains unexplained," said Dr. Kavitha Chinnaiyan, director of cardiac imaging at Beaumont Hospital in Royal Oak, Mich. "Psychosocial factors likely play a role in these unexplained cases. More and more studies have been looking at stress, anger, sudden stress and major life changes like losing a job, and all of these can have a major effect on cardiovascular events," she said.

One recent study, published Nov. 19 in the Archives of Internal Medicine, found that the risk for heart attack increased significantly for middle-aged to elderly people when they were unemployed. The researchers also found that the risks increased incrementally with each subsequent job loss.

Losing a job, however, doesn't mean automatic heart problems, especially if you take steps to protect your heart's health.

"Decreasing stress hormones is important," Chinnaiyan said. "We know from studies that behaviors such as meditation, yoga and tai chi work specifically to reduce our response to stress."

Meditation, one of Chinnaiyan's favorite ways to reduce stress, "can help in multiple ways," she said. "It helps you see your choices and have a clearer perspective of what to do next. Stress may still be around us, but meditation gives us a better ability to cope with it." Yoga can also be quite helpful in decreasing stress-related hormones, she added.
