Risk

On Monday, researchers at the Harvard School of Public Health released study results showing that red meat consumption was associated with a higher risk of early death. The more red meat -- beef, pork or lamb, for the purposes of the research -- study participants reported they ate, the more likely they were to die during the period of time that data collection took place (more than 20 years). So what is it in red meat that might make it unhealthy?   No one is sure, exactly, but the authors of the Harvard study mention a few possible culprits in their paper in the Archives of Internal Medicine .   First, eating red meat has been linked to the incidence of heart disease.  The saturated fat and cholesterol in beef, pork and lamb are believed to play a role in the risk of coronary heart disease .  The type of iron found in red meat, known as heme iron, has also been linked to heart attacks and fatal heart disease.  Sodium in processed meats may increase blood pressure, which is a risk factor for heart disease. Other chemicals that are used in processed meats may play a role in heart disease as well, by damaging blood vessels.

Taking calcium supplements increases the risk of having a heart attack, Swiss and German researchers reported Wednesday. The finding adds to the growing body of evidence that such supplements increase the risk to those who take them while providing only minimal benefits. The study is considered important because large numbers of people, especially elderly women, continue to take the supplements in hopes of minimizing loss of bone density.

A stream of highly charged particles from the sun is headed straight toward Earth, threatening to plunge cities around the world into darkness and bring the global economy screeching to a halt. This isn't the premise of the latest doomsday thriller. Massive solar storms have happened before - and another one is likely to occur soon, according to Mike Hapgood, a space weather scientist at the Rutherford Appleton Laboratory near Oxford, England. Much of the planet's electronic equipment, as well as orbiting satellites, have been built to withstand these periodic geomagnetic storms.

An environmental group that has supported a proposed downtown Los Angeles football stadium and helped the developer secure special treatment in the courts issued a sharply worded critique Tuesday of environmental documents prepared for the project. In a 16-page letter to city officials, the Natural Resources Defense Council called on Anschutz Entertainment Group to rewrite and recirculate a recently released environmental impact report on the proposed stadium, saying it failed to fully analyze health risks created by cars that would travel to and from the 72,000-seat facility.

The Food and Drug Administration on Thursday cautioned consumers against using quinine for leg cramps, warning that the drug could cause severe side effects, including death. Quinine, sold in this country under the brand name Qualaquin, is approved for treatment of uncomplicated malaria, but has a long history of use as a remedy for leg cramps, especially at night. In many countries, it is sold over the counter. Studies have shown that it can reduce the incidence of cramps by one-third to one-half but that as many as one in every 25 users can suffer serious side effects.

In an age of long commutes, late sports practices, endless workdays and 24/7 television programming, the image of Mom hanging up her dish towel at 7 p.m. and declaring "the kitchen is closed" seems a quaint relic of an earlier era. It also harks back to a thinner America. And that may be no coincidence. A new study, conducted on mice, hints at an unexpected contributor to the nation's epidemic of obesity - and, if later human studies bear it out, a possible way to have our cake and eat it too, with less risk of weight gain and the diseases that come with it. Just eat your cake - or better yet, an apple - earlier.

Researchers have some reassuring news for the legions of coffee drinkers who can't get through the day without a latte, cappuccino, iced mocha, double-shot of espresso or a plain old cuppa joe: That coffee habit may help you live longer. A new study that tracked the health and coffee consumption of more than 400,000 older adults for nearly 14 years found that java drinkers were less likely to die during the study than their counterparts who eschewed the brew. In fact, men and women who averaged four or five cups of coffee per day had the lowest risk of death, according to a report in Thursday's edition of the New England Journal of Medicine.

Distancing himself from Republicans on housing issues, President Obama pitched a $5-billion to $10-billion plan to help a key segment of struggling homeowners — those still making monthly payments, but on underwater mortgages. Obama proposed Wednesday to help about 3.5 million people with good credit who are unable to refinance at historically low rates because their homes are worth less than their mortgages. He argued that those homeowners — and the country — couldn't afford to let the housing market bottom out, as many Republicans, including presidential candidate Mitt Romney, have advocated.

The PSA test should be abandoned as a prostate cancer screening tool, a government advisory panel has concluded after determining that the side effects from needless biopsies and treatments hurt many more men than are potentially helped by early detection of cancers. At best, one life will be saved for every 1,000 men screened over a 10-year period, according to the U.S. Preventive Services Task Force. But 100 to 120 men will have suspicious results when there is no cancer, triggering biopsies that can carry complications such as pain, fever, bleeding, infection and hospitalization.

Sprouted-grain bread offerings in the market have been slowly but steadily on the uptick of late, and a number of health claims have attached themselves to the spongy, nutty-tasting loaves: more digestible, richer in protein and higher in vitamins and minerals compared with other breads. But are the claims true? Yes -- and no. Sprouted-grain products have distinct nutritional advantages over white breads, but when compared to other whole-grain breads, they're usually nutritionally comparable -- although nutrient contents can vary, depending on the sprouts included.

For postmenopausal women who are obese, breast cancer is more likely. That's because fat tissue seems to behave essentially as an organ of the endocrine system, pumping out the hormone estrogen. And estrogen is a driver of many common breast cancers. But losing as little as 5% of one's body weight - 10 pounds for a 200-pound woman - drives down levels of estrogen and other hormones that raise breast cancer risk, a new study finds. In combination with weight loss, exercise drove down hormone levels even more, an effect that is likely to reduce a woman's risk of developing breast cancer.

As the United States finally begins to wind down its military presence in Afghanistan, is the Obama administration poised to replicate that intervention in Yemen? The administration insists it has no such plans, but it has been evident for months that it regards the Yemen-based group Al Qaeda in the Arabian Peninsula as the most dangerous incubator of terrorist plots directed at America. And it is acting on that conviction. This week The Times reported that U.S. special operations troops, which were withdrawn from Yemen last year amid political turmoil in that country, have returned and are providing technical assistance to Yemeni forces.

Dodgers Manager Don Mattingly said Sunday that the team doctor told him second baseman Mark Ellis was within several hours of possibly having his left leg amputated if Ellis hadn't had emergency surgery. "That was scary," Mattingly said of the injury, which is expected to keep Ellis out of action for six weeks. "I didn't realize how bad that was. " Ellis, 34, suffered the injury Friday when he was upended by the St. Louis Cardinals' Tyler Greene to break up a double play.

ATHENS - Fear for the health ofGreece's banks increased Wednesday after a rush of withdrawals as the country braces for fresh elections that could determine whether it remains part of the Eurozone. Reports that depositors pulled out nearly $1 billion on a single day fueled warnings this week from the Greek president of a run on already shaky financial institutions. There were no lines of worried customers outside banks in Athens on Wednesday, but one analyst said a panic could easily be sparked in the country's febrile political and economic environment.

In a rational world, a corporate chairman who presided over a huge unexpected loss would be raked over the coals at his next shareholder meeting and his job would be up for grabs. It's not likely that will happen to JPMorgan Chase Chairman and Chief Executive Jamie Dimon at the firm's annual shareholder meeting today. Partly that's because "shareholder democracy" is a joke at almost all big companies. Dissident shareholders typically rejoice at getting a 40% backing for their proposals.

A federal administrative judge ruled that pomegranate juice maker Pom Wonderful used deceptive advertising when it implied its products could treat or prevent serious diseases and other medical conditions. Judge D. Michael Chappell upheld much of a 2010 Federal Trade Commission complaint against the Los Angeles company owned by Lynda and Stewart Resnick. The judge said in his decision issued Monday that Pom used "insufficient" evidence to back its claims that Pom products "treat, prevent or reduce the risk of heart disease, prostate cancer or erectile dysfunction.

Disco legend Donna Summer, 63, died Wednesday night, reportedly of lung cancer. As of press time, her family hadn't released details about her illness, so it was unknown what type of lung cancer she had, and how long she may have been ailing. According to the American Cancer Society , lung cancer is the leading cause of cancer death in both women and men, killing more than 150,000 people per year -- more than colon, breast, ovarian and prostate cancers combined. In 2012, the group estimates, there will be about 226,000 new cases of lung cancer in the U.S. Survival rates of people with lung cancer are low. Only about half of people diagnosed with early-stage non-small-cell lung cancer (the more common type)

If California starts building a 130-mile segment of high-speed rail late this year as planned, it will enter into a risky race against a deadline set up under federal law. The bullet train track through the Central Valley would cost $6 billion and have to be completed by September 2017, or else potentially lose some of its federal funding. It would mean spending as much as $3.5 million every calendar day, holidays and weekends included -- the fastest rate of transportation construction known in U.S. history, according to industry and academic experts.

LISBON - For Francisco Reposo, the 30% pay cut he was forced to take this year amid government austerity measures is the least of his worries. The high school science teacher is also on dialysis, awaiting a kidney operation, and Portugal's financial bailout means he's saddled with hundreds of dollars in monthly medical bills. The cost of seeing a doctor in Portugal has more than doubled, from about $12 to $26 a visit. Reposo used to pay nothing for dialysis because he's a blood donor, but that exemption was lifted, and he now pays about $53 for each session.
