Higher Cancer Rates Due More to Longer Life Spans than to Modern Life Styles

Often thought of as a modern disease, cancer has always been with us.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. D1) When they excavated a Scythian burial mound in the Russian region of Tuva about 10 years ago, archaeologists literally struck gold. Crouched on the floor of a dark inner chamber were two skeletons, a man and a woman, surrounded by royal garb from 27 centuries ago: headdresses and capes adorned with gold horses, panthers and other sacred beasts.

But for paleopathologists — scholars of ancient disease — the richest treasure was the abundance of tumors that had riddled almost every bone of the man’s body. The diagnosis: the oldest known case of metastasizing prostate cancer.
The prostate itself had disintegrated long ago. But malignant cells from the gland had migrated according to a familiar pattern and left identifiable scars. Proteins extracted from the bone tested positive for PSA, prostate specific antigen.
Often thought of as a modern disease, cancer has always been with us.
. . .
(p. D7) . . . , Tony Waldron, a paleopathologist at University College London, analyzed British mortality reports from 1901 to 1905 — a period late enough to ensure reasonably good records and early enough to avoid skewing the data with, for example, the spike in lung cancer caused in later decades by the popularity of cigarettes.
Taking into account variations in life span and the likelihood that different malignancies will spread to bone, he estimated that in an “archaeological assemblage” one might expect cancer in less than 2 percent of male skeletons and 4 to 7 percent of female skeletons.
Andreas G. Nerlich and colleagues in Munich tried out the prediction on 905 skeletons from two ancient Egyptian necropolises. With the help of X-rays and CT scans they diagnosed five cancers — right in line with Dr. Waldron’s expectations. And as his statistics predicted, 13 cancers were found among 2,547 remains buried in an ossuary in southern Germany between A.D. 1400 and 1800.
For both groups, the authors wrote, malignant tumors “were not significantly fewer than expected” when compared with early-20th-century England. They concluded that “the current rise in tumor frequencies in present populations is much more related to the higher life expectancy than primary environmental or genetic factors.”
. . .
“Cancer is an inevitability the moment you create complex multicellular organisms and give the individual cells the license to proliferate,” said Dr. Weinberg of the Whitehead Institute. “It is simply a consequence of increasing entropy, increasing disorder.”
He was not being fatalistic. Over the ages bodies have evolved formidable barriers to keep rebellious cells in line. Quitting smoking, losing weight, eating healthier diets and taking other preventive measures can stave off cancer for decades. Until we die of something else.
“If we lived long enough,” Dr. Weinberg observed, “sooner or later we all would get cancer.”

Modern Lifestyles May Not Be Cause of Heart Disease

MummyCTscan2010-12-21.jpg“MODERN MEETS ANCIENT. CT scans of some Egyptian mummies, like the one being done on this priest, reveal signs of atherosclerosis.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. D6) . . . a team of cardiologists used CT scanning on mummies in the Egyptian National Museum of Antiquities in Cairo to identify atherosclerosis — a buildup of cholesterol, inflammation and scar tissue in the walls of the arteries, a problem that can lead to heart attack and stroke.

The cardiologists were able to identify the disease in some mummies because atherosclerotic tissue often develops calcification, which is visible as bright spots on a CT image. The finding that some mummies had hardened arteries raises questions about the common wisdom that factors in modern life, including stress, high-fat diets, smoking and sedentary routines, play an essential role in the development of cardiovascular disease, the researchers said.
“It tells us that we have to look beyond lifestyles and diet for the cause and progression of this disease,” said Dr. Randall C. Thompson, a cardiologist at St. Luke’s Mid America Heart Institute in Kansas City, Mo., and part of the team of cardiovascular imaging specialists who traveled to Cairo last year. “To a certain extent, getting the disease is part of the human condition.”

Government Mandates Insurers Pay for $4,300 Tests on Potential Donors Recruited by $60,000 a Week “Flirtatious Models”

(p. A16) BOSTON — On its face, it seemed reasonable enough: a bone marrow registry sending recruiters to malls, ballparks and other busy sites to enlist potential donors.

But the recruiters were actually flirtatious models in heels, short skirts and lab coats, law enforcement officials say, asking passers-by for DNA swabs without mentioning the price of the seemingly simple procedure. And the registry, Caitlin Raymond International, was paying up to $60,000 a week for the models while billing insurance companies up to $4,300 per test.
. . .
The registry is a nonprofit subsidiary of UMass Memorial Medical Center in Worcester, . . .
. . .
James T. Boffetti, the state’s senior assistant attorney general, said the registry had hired models based on their photographs and had given them “explicit instructions” to wear heels and short skirts.
. . .
New Hampshire passed a law in 2006 requiring insurers to pay for tissue-typing tests for potential bone marrow donors.

Under Health Care ‘Reform’ the Total Cost of Health Care Will “Go through the Roof!”

BushJonathanAthenahealth2010-12-20.jpg

“Jonathan Bush, nephew of one former president and cousin of another, built a small medical practice into a national enterprise with nearly 1,200 employees.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. B10) In the world of health care innovation, the founder and chief executive of Athenahealth has an outsize name. In part, that’s because his name is Jonathan Bush, and he is the nephew of one former president and the cousin of another. But it’s also because his company has mastered the intricacies of the doctor-insurer relationship and become a player in the emerging medical records industry.

Based in Watertown, Mass., Athenahealth offers a suite of administrative services for medical practices. It collects payments from insurers and patients, and it manages electronic health records and patient communication systems. All of this is done remotely through the Internet — or “in the cloud,” as Mr. Bush puts it. Doctors don’t have to install or manage software or pay licensing fees; instead, Athenahealth keeps a percentage of the revenue.
. . .
Q. What’s going on in the health care industry to deliver that kind of growth to you?
A. We are a disruptive technology. We are the only cloud-based service in an industry segment full of sclerotic, enormous, personality-free corporations that have been in business making 90 percent margins doing nothing for decades and decades.
Q. What keeps other companies from building cloud-based systems?
A. For software companies, the biggest barrier to entry is that they give up their business model. Those companies would get hammered on Wall Street if they started selling a service that they have to deliver at a loss for five years. In terms of new entrants, there are two things that we’ve done that would take a good decade to replicate. One, we’ve built out the health care Internet. We’ve been building connections into insurance companies and laboratories and hospital medical records for years and years and years.
And the other barrier to entry is that rules engine. Every time a doctor anywhere in the country gets a claim denied, we have analysts ask the Five Whys. When we get to root cause, we write a new rule into Athenanet and from that day on, no other doctor gets that particular denial from that particular insurance company ever again. We now know of 40 million ways that a doctor can have a claim denied in the United States. The average practice has to rework about 35 percent of their claims, and we only have to rework about 5 percent of ours.
Q. What’s the prognosis for bill collecting under health care reform?
A. Well, there’s going to be new connectors and a whole series of new insurance products that will be managed by the states’ health insurance commissioners. And the law provides for every state to do all of these its own way, so they will have their own rules and regulations, and each state will do it differently. That sounds like springtime in Complexity Land.
Q. What do you think will happen to the total cost of health care under reform?
A. Oh, it’s going to go through the roof! It’s widely accepted that this is not a cost-reform bill — it’s an access bill. It’s in fact a cost-expansion bill.

Neurosurgeons Treating Dogs is Mutually Beneficial to Dogs and Humans

(p. D3) An operation commonly performed to remove brain tumors from the pituitary glands of humans is now available to dogs, thanks to a collaboration between a neurosurgeon and some veterinarians in Los Angeles. And that is turning out to be good for humans.

So far, nine dogs and one cat that otherwise would have died have been treated successfully.
. . .
What Dr. Mamelak has gained from teaching the procedure to veterinarians is access to tissue samples from the treated dogs. That’s significant because Cushing’s afflicts only one in a million humans, making it a difficult disease to study. By contrast, it afflicts about 100,000 dogs a year in the United States. The canine tissue samples are enabling him and his colleagues to develop drugs to one day treat Cushing’s disease in both humans and dogs.
“We have a full loop,” he said. “We’re using a human procedure in animals, and using their tissue to study the disease.”

Feds Chastise Us for Being Fat AND Urge Us to Eat More Cheese Pizzas

PizzaCheeseFat2010-11-08.jpg “A government-created industry group worked with Domino’s Pizza to bolster sales by increasing the cheese on pies.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. 1) Domino’s Pizza was hurting early last year. Domestic sales had fallen, and a survey of big pizza chain customers left the company tied for the worst tasting pies.

Then help arrived from an organization called Dairy Management. It teamed up with Domino’s to develop a new line of pizzas with 40 percent more cheese, and proceeded to devise and pay for a $12 million marketing campaign.
Consumers devoured the cheesier pizza, and sales soared by double digits. “This partnership is clearly working,” Brandon Solano, the Domino’s vice president for brand innovation, said in a statement to The New York Times.
But as healthy as this pizza has been for Domino’s, one slice contains as much as two-thirds of a day’s maximum recommended amount of saturated fat, which has been linked to heart disease and is high in calories.
And Dairy Management, which has made cheese its cause, is not a private business consultant. It is a marketing creation of the United States Department of Agriculture — the same agency at the center of a federal anti-obesity drive that discourages over-consumption of some of the very foods Dairy Management is vigorously promoting.
. . .
When Michelle Obama implored restaurateurs in September to help fight obesity, she cited the proliferation of cheeseburgers and macaroni and cheese. “I (p. 23) want to challenge every restaurant to offer healthy menu options,” she told the National Restaurant Association’s annual meeting.
But in a series of confidential agreements approved by agriculture secretaries in both the Bush and Obama administrations, Dairy Management has worked with restaurants to expand their menus with cheese-laden products.

Being Bilingual Increases “Cognitive Reserve”

BilingualDementia2010-10-23.gif

Source of graph: online version of the WSJ article quoted and cited below.

At first glance the graph and the text quoted below seem inconsistent on whether bilingualism delays the onset of dementia. The text says no, the graph says yes. On closer reading, the text is referring to the “physical signs of deterioration” while the graph is referring to “visible symptoms.”

(p. D1) A lifetime of speaking two or more languages appears to pay off in old age, with recent research showing the symptoms of dementia can be delayed by an average of four years in bilingual people.

Multilingualism doesn’t delay the onset of dementia–the brains of people who speak multiple languages still show physical signs of deterioration–but the process of speaking two or more languages appears to enable people to develop skills to better cope with the early symptoms of memory-robbing diseases, including Alzheimer’s.
Scientists for years studied children and found that fluently speaking more than one language takes a lot of mental work. Compared with people who speak only one language, bilingual children and young adults have slightly smaller vocabularies and are slower performing certain verbal tasks, such as naming lists of animals or fruits.
But over time, regularly speaking more than one language appears to strengthen skills that boost the brain’s so-called cognitive reserve, a capacity to work even when stressed or damaged. This build-up of cognitive reserve appears to help bilingual people as they age.

Paleolithic Humans Ate Carbohydrates

(p. D4) LONDON (Reuters) — Starch grains found on 30,000-year-old grinding stones suggest that prehistoric humans may have dined on an early form of flatbread, contrary to their popular image as primarily meat eaters.

The findings, published in The Proceedings of the National Academy of Sciences journal on Monday, indicate that Paleolithic Europeans ground down plant roots similar to potatoes to make flour, which was later whisked into dough.
“It’s like a flatbread, like a pancake with just water and flour,” said Laura Longo, a researcher on the team, from the Italian Institute of Prehistory and Early History.
. . .
The findings may . . . upset fans of the so-called Paleolithic diet, which follows earlier research that assumes early humans ate a meat-centered diet.

Wilderness Act Makes Wilderness Inaccessible and Dangerous

(p. A19) ONE day in early 1970, a cross-country skier got lost along the 46-mile Kekekabic Trail, which winds through the Boundary Waters Canoe Area Wilderness in northern Minnesota. Unable to make his way out, he died of exposure.

In response, the Forest Service installed markers along the trail. But when, years later, it became time to replace them, the agency refused, claiming that the 1964 Wilderness Act banned signage in the nation’s wilderness areas.
. . .
Over the decades an obvious contradiction has emerged between preservation and access. As the Forest Service, the National Park Service and the Bureau of Land Management — each of which claims jurisdiction over different wilderness areas — adopted stricter interpretations of the act, they forbade signs, baby strollers, certain climbing tools and carts that hunters use to carry game.
As a result, the agencies have made these supposedly open recreational areas inaccessible and even dangerous, putting themselves in opposition to healthy and environmentally sound human-powered activities, the very thing Congress intended the Wilderness Act to promote.

Obamacare Is Increasing Health Costs

HealthOutlays2010-10-01.gif

Source of graph: online version of the WSJ article quoted and cited below.

(p. A7) The health-care overhaul enacted last spring won’t significantly change national health spending over the next decade compared with projections before the law was passed, according to government figures released Thursday.

The report by federal number-crunchers casts fresh doubt on Democrats’ argument that the health-care law would curb the sharp increase in costs over the long term, the second setback this week for one of the party’s biggest legislative achievements.
The Wall Street Journal reported Wednesday that insurance companies have proposed rate increases ranging from 1% to 9% nationwide that they attribute specifically to new health-law coverage mandates.
