Health “Halos” Con Calorie Counters

Scientific American, Steve Mirsky | November 19, 2010

When it comes to counting calories, a mind is a terrible thing to your waist.

Yiddish literature includes numerous stories about the mythical village of Chelm, filled with people who, well, let’s put it this way: they are not likely to graduate first in their Yeshiva class. One such tale involves befuddled carpenters who could not figure out why, no matter how many times they cut additional pieces off the ends of a board, it was still too short. Oy.

Now new research shows that when it comes to food, most people are honorary citizens of Chelm. Investigator Alexander Chernev, for one, has discovered that many people believe they can cut a meal’s calorie count by an ingenious method—adding more food! Oy.

Chernev, who investigates consumer behavior at Northwestern University’s Kellogg (snap, crackle, pop) School of Management, spends an inordinate amount of time around hamburgers for a guy who’s not managing a McDonald’s. Publishing in theJournal of Consumer Psychology, he explains that people act as if healthful foods have “halos”—their healthfulness extends to the rest of the meal. Vegetables and fruit: big halos. Angel food cake: no halo. Go figure.

Here is where the mind applies cockamamie calculus to meals. Eaters consider a food’s health fulness to be related to how “fattening” it is. “Because healthier meals are perceived to be less likely to promote weight gain,” Chernev writes, “people erroneously assume that adding a healthy item to a meal decreases its potential to promote weight gain.” More is less, more or less.

He had more than 900 subjects look at four different meals and estimate their calorie contents. The meals were a hamburger, a bacon-and-cheese waffle sandwich, chili with beef and a meatball-pepperoni cheesesteak—none of which are going to win any prizes from the American Heart Association, and all of which sound really good right now.

Worker Wellness and Reducing the Spread of Germs

Marianne Santangelo, EHS Today

Every year, the cold and flu season takes its toll on U.S. industry, sidelining workers and derailing production. If you control the spread of germs in the workplace, you might reduce the number of cases of flu suffered by your employees.

The flu, as well as other viruses, can lead to losses in workplace productivity due to absenteeism from workers who are themselves sick or those who must stay home to care for others.

Up to 20 percent of the population gets the seasonal flu annually, while more than 200,000 people are hospitalized with flu-related complications. Some 36,000 people in this country die from flu-related causes each year.

Flu seasons are unpredictable in a number of ways, including when they begin, how severe they are, how long they last and which viruses will spread. The emergence of the H1N1 influenza virus in 2009 caused the first influenza pandemic in more than 40 years, which led to more uncertainties than usual and high levels of flu activity much earlier in the year than during most regular flu seasons.

The economic consequences of a flu pandemic are daunting. A 2005 study by the Centers for Disease Control and Prevention (CDC) estimated that the impact of a flu pandemic would be $71.3 to $166.5 billion, excluding disruptions to commerce and society.

Cox, and Keiji Fukuda, Centers for Disease Control and Prevention, Atlanta.)

Cholera Rages in Rural Haiti, Overwhelming Clinics

BEN FOX, Associated Press, Dec 3, 2010

LIMBE, Haiti – A gray-haired woman, her eyes sunken and unfocused from dehydration, stumbles up a dirt path slumped on the shoulder of a young man, heading to a rural clinic so overcrowded that plastic tarps have been strung up outside to shade dozens who can’t fit inside.

On the path to the clinic, another cholera victim lies dazed, her head bleeding because she couldn’t stay atop the motorcycle taxi that carried her along the twisting country roads to the treatment center on the front line of Haiti’s sudden battle with cholera.

Nearby, a 16-month-old girl wails as a nurse prods her with a needle, trying to find a vein for the intravenous fluids she needs to save her life.

Many feared Haiti’s growing epidemic would overwhelm a capital teeming with more than 1 million people left homeless by January’s earthquake. But, so far, it is the countryside seeing the worst of an epidemic that has killed nearly 1,900 people since erupting less than two months ago.

Rural clinics are overrun by a spectral parade of the sick, straining staff and supplies at medical outposts that could barely handle their needs before the epidemic.

At the three-room clinic near Limbe, in northern Haiti, a handful of doctors and nurses are treating 120 people packed into three rooms.

“It’s really attacking us,” Guy Valcoure, grandfather of the 16-month-old, says of the cholera. He piled on the back of a motorcycle with the baby and her mother to make a 40-minute ride in pre-dawn gloom to reach the clinic.

In New Insurance Model, Costs are Based on Value of the Treatment

Michelle Andrews, Kaiser Health News, November 30, 2010

What if, instead of making a $10 insurance copayment for your cholesterol lowering drug, your employer provided it and other drugs to manage chronic conditions for free? What if your company also paid for weight management and smoking cessation classes? You’d probably give your employer high marks for looking out for your health.

Now, what if your employer said that if you want certain procedures that it’s determined are overused, like an MRI or knee surgery, you’ll have to pay up to $500 extra, on top of your other coinsurance charges? Those employer decisions might not be nearly as welcome.

Both, however, are part of an approach to health care that shares a common perspective: The idea that consumers’ out-of-pocket medical costs should be based on the value of a medical service to their health rather than its price.

Although still relatively rare, the model is garnering increasing attention among employers, insurers and policy experts. Mercer, a benefits consulting company, found in a 2008 survey that 19 percent of employers with at least 500 employees were charging workers less for services the companies considered to have a higher value for workers’ health. In addition, more than 80 percent of employers with at least 10,000 workers surveyed by Mercer in 2007 said they were interested in adopting this model in the next five years, according to a paper published in the November issue of Health Affairs. It was one of several on value-based insurance design, as it’s called, in the current issue.

Some health law provisions also embrace value-based insurance principles, including the requirement that new insurance policies provide free recommended preventive services such as mammograms andcolon cancer screenings starting in 2011. “It’s all in keeping with the idea that some things are so valuable to health care that there should be no barriers to their use,” says Dr. Niteesh Choudhry, an assistant professor at Harvard Medical School and lead author of two of the articles in this month’s Health Affairs.

A landmark 1982 study showed that as out-of-pocket costs rise, consumers spend less on health care services. But they scrimp not just on care that’s ineffective or unnecessary but also on care that they need, treatment that’s highly effective at addressing their condition.

Fuel Lines of Tumors Are New Target

ANDREW POLLACK, New York Times, November 29, 2010

For the last decade cancer drug developers have tried to jam the accelerators that cause tumors to grow. Now they want to block the fuel line.

Cancer cells, because of their rapid growth, have a voracious appetite for glucose, the main nutrient used to generate energy. And tumors often use glucose differently from healthy cells, an observation first made by a German biochemist in the 1920s.

That observation is already used to detect tumors in the body using PET scans. A radioactive form of glucose is injected into the bloodstream and accumulates in tumors, lighting up the scans.

Now, efforts are turning from diagnosis to treating the disease by disrupting the special metabolism of cancer cells to deprive them of energy.

The main research strategy of the last decade has involved so-called targeted therapies, which interfere with genetic signals that act like accelerators, causing tumors to grow. But there tend to be redundant accelerators, so blocking only one with a drug is usually not enough.

In theory, however, depriving tumors of energy should render all the accelerators ineffective.

“The accelerators still need the fuel source,” said Dr. Chi Dang, a professor of medicine and oncology at Johns Hopkins University. Indeed, he said, recent discoveries show that the genetic growth signals often work by influencing cancer cells’ metabolism.

The efforts to exploit cancer’s sweet tooth are in their infancy, with few drugs in clinical trials. But interest is growing among pharmaceutical companies and academic researchers.

“Nutrient supply and deprivation is becoming potentially the next big wave,” said Dr. David Schenkein, chief executive of Agios Pharmaceuticals, a company formed two years ago to develop drugs that interfere with tumor metabolism. Among its founders was Dr. Craig B. Thompson, the new president of Memorial Sloan-Kettering Cancer Center in New York City.

Report Questions Need for 2 Diet Supplements

GINA KOLATA, New York Times, November 29, 2010

The very high levels of  vitamin D that are often recommended by doctors and testing laboratories — and can be achieved only by taking supplements — are unnecessary and could be harmful, an expert committee says. It also concludes that calcium supplements are not needed.

The group said most people have adequate amounts of vitamin D in their blood supplied by their diets and natural sources like sunshine, the committee says in a report that is to be released on Tuesday.

“For most people, taking extra calcium and vitamin D supplements is not indicated,” said  Dr. Clifford J. Rosen, a member of the panel and an osteoporosis expert at the Maine Medical Center Research Institute.

Dr. J. Christopher Gallagher, director of the bone metabolism unit at the Creighton University School of Medicine in Omaha, Neb., agreed, adding, “The onus is on the people who propose extra calcium and vitamin D to show it is safe before they push it on people.”

Over the past few years, the idea that nearly everyone needs extra calcium and vitamin D — especially vitamin D — has swept the nation.

With calcium, adolescent girls may be the only group that is getting too little, the panel found. Older women, on the other hand, may take too much, putting themselves at risk for kidney stones. And there is evidence that excess calcium can increase the risk of heart disease, the group wrote.

As for vitamin D, some prominent doctors have said that most people need supplements or they will be at increased risk for a wide variety of illnesses, including heart disease, cancer and autoimmune diseases.

American Human Development Project

Measure of America [measureofamerica.org] aims to stimulate fact-based discussion about issues regarding the topics of Health, Education and Income. By encouraging for a greater understanding of the opportunities and constraints of ordinary people, Measure of America tries to answer at least 2 important questions: “How is the economy is doing?”, but also “How are the people doing?”

The different maps and visualizations are based on the “American Human Development Index”, a composite measure of well-being and opportunity that combines indicators in 3 fundamental areas, including health, knowledge, and standard of living, into a single number on a scale from 0 to 10. Health is measured using life expectancy, calculated from mortality data from the Centers for Disease Control and Prevention. Knowledge is determined using 2 different indicators: school enrollment and degree attainment. Both indicators are from the U.S. Census Bureau. Standard of living is defined using median earnings of all workers 16 and older, also from the Census Bureau.

Health Law Faces Threat of Undercut From Courts

KEVIN SACK and ROBERT PEAR, New york Times, November 26, 2010

WASHINGTON — As the Obama administration presses ahead with the health care law, officials are bracing for the possibility that a federal judge in Virginia will soon reject its central provision as unconstitutional and, in the worst case for the White House, halt its enforcement until higher courts can rule.

The judge, Henry E. Hudson of Federal District Court in Richmond, has promised to rule by the end of the year on the constitutionality of the law’s requirement that most Americans obtain insurance, which takes effect in 2014.

Although administration officials remain confident that it is constitutionally valid to compel people to obtain health insurance, they also acknowledge that Judge Hudson’s preliminary opinions and comments could presage the first ruling against the law.

“He’s asked a number of questions that express skepticism,” said one administration official who is examining whether a ruling against part of the law would undermine other provisions. “We have been trying to think through that set of questions,” said the official, who insisted on anonymity because he was not authorized to discuss the case freely.

While many newly empowered Republican lawmakers have vowed to repeal the health care law in Congress, a more immediate threat may rest in the federal courts in cases brought by Republican officials in dozens of states. Not only would an adverse ruling confuse Americans and attack the law’s underpinnings, it could frustrate the steps hospitals, insurers and government agencies are taking to carry out the law.

A DEADLY MISDIAGNOSIS

Michael Specter, The New Yorker, November 11, 2010

101115_r20176_p465Is it possible to save the millions of people who die from TB?

Every afternoon at about four, a slight woman named Runi slips out of the cramped, airless room that she shares with her husband and their sixteen children. She skirts the drainage ditch in front of the building, then walks toward the pile of hardened dung cakes that people in this slum on the edge of the northeastern Indian city of Patna use for fuel. Dressed in a bright-yellow sari shot with gold threads, Runi is followed by several of her children. Although she can’t remember their ages, or her own, Runi must be about forty, because she dates her life from its first crucial memory: the smallpox epidemic that devastated Patna and much of surrounding Bihar province in 1974.

Runi survived that plague, and several others, but, about a year ago, after developing a persistent cough, she visited one of the private medical clinics that line the streets of Patna. There someone who called himself a doctor stuck a needle in her arm, drew a few drops of blood, examined them, and told her that she had tuberculosis. It is not an uncommon diagnosis. Tuberculosis has always been the signature disease of urban poverty, passed easily in poorly ventilated spaces. India has nearly two million new cases each year, and every day a thousand people die of the disease, the highest number in the world. Tuberculosis is also the leading cause of death among people between fifteen and forty-five—the most productive age group in any country and the key to India’s prospects for continued economic growth.

For most patients, the choices are bleak. Public hospitals are so overcrowded that people are forced to rely on inaccurate tests dispensed at private labs and clinics. They are unregulated enterprises, and peddle blood tests that are responsible for tens of thousands of misdiagnoses every year. “This is deadly,” L. S. Chauhan, the director of the National TB Control Program, told me when we met in New Delhi. “But there are thousands of labs. Shut one down and the next day ten more appear.”
