Medieval Halls of the Rich Incubated Plague in a Nest of “Filth Unmentionable”

(p. 51) In even the best houses, floors were generally just bare earth strewn with rushes, harboring “spittle and vomit and urine of dogs and men, beer that hath been cast forth and remnants of fishes and other filth unmentionable,” as the Dutch theologian and traveler Desiderius Erasmus rather crisply summarized in 1524. New layers of rushes were laid down twice a year normally, but the old accretions were seldom removed, so that, Erasmus added glumly, “the substratum may be unmolested for twenty years.” The floors were in effect a very large nest, much appreciated by insects and furtive rodents, and a perfect incubator for plague. Yet a deep pile of flooring was generally a sign of prestige. It was common among the French to say of a rich man that he was “waist deep in straw.”

In Medicine, as Elsewhere, What Pays Is Usually What Gets Done

LevinDonaldPsychiatrist2011-06-05.jpg “”I had to train myself not to get too interested in their problems, and not to get sidetracked trying to be a semi-therapist.” Dr. Donald Levin, a psychiatrist whose practice no longer includes talk therapy.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) DOYLESTOWN, Pa. — Alone with his psychiatrist, the patient confided that his newborn had serious health problems, his distraught wife was screaming at him and he had started drinking again. With his life and second marriage falling apart, the man said he needed help.

But the psychiatrist, Dr. Donald Levin, stopped him and said: “Hold it. I’m not your therapist. I could adjust your medications, but I don’t think that’s appropriate.”
Like many of the nation’s 48,000 psychiatrists, Dr. Levin, in large part because of changes in how much insurance will pay, no longer provides talk therapy, the form of psychiatry popularized by Sigmund Freud that dominated the profession for decades. Instead, he prescribes medication, usually after a brief consultation with each patient. So Dr. Levin sent the man away with a referral to a less costly therapist and a personal crisis unexplored and unresolved.

Warm Yourself Over a “Dung Fire, and You Will Know What Pollution Really Is”

(p. D4) To the Editor:
The idea that ancient man had fewer tumors because he lived in a less polluted atmosphere (“Unearthing Prehistoric Tumors, and Debate,” Dec. 28) can be held only by those who have limited experience living in a preindustrial way. Try cooking over an open fire burning half-rotten wood, or sitting in a cave warming yourself with a peat or dung fire, and you will know what pollution really is.

Laron Syndrome Villagers Free of Cancer and Diabetes, Suggesting Longevity Breakthrough

LoranSyndromeCancerDiabetesGraphic2011-06-05.jpg

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

(p. A6) People living in remote villages in Ecuador have a mutation that some biologists say may throw light on human longevity and ways to increase it.

The villagers are very small, generally less than three and a half feet tall, and have a rare condition known as Laron syndrome or Laron-type dwarfism. They are probably the descendants of conversos, Sephardic Jews from Spain and Portugal who were forced to convert to Christianity in the 1490s but were nonetheless persecuted in the Inquisition. They are also almost completely free of two age-related diseases, cancer and diabetes.
A group of 99 villagers with Laron syndrome has been studied for 24 years by Dr. Jaime Guevara-Aguirre, an Ecuadorean physician and diabetes specialist.
. . .
IGF-1 is part of an ancient signaling pathway that exists in the laboratory roundworm as well as in people. The gene that makes the receptor for IGF-1 in the roundworm is called DAF-2. And worms in which this gene is knocked out live twice as long as normal.
The Laron patients have the equivalent defect — their cells make very little IGF-1, so very little IGF-1 signaling takes place, just as in the DAF-2-ablated worms. So the Laron patients might be expected to live much longer.
Because of their striking freedom from cancer and diabetes, they probably could live much longer if they did not have a much higher than usual death rate from causes unrelated to age, like alcoholism and accidents.
. . .
A strain of mice bred by John Kopchick of Ohio University has a defect in the growth hormone receptor gene, just as do the Laron patients, and lives 40 percent longer than usual.
. . .
The longest-lived mouse on record is one studied by Dr. Bartke. It had a defect in its growth hormone receptor gene, just as do the Laron patients. “It missed its fifth birthday by a week,” he said. The mouse lived twice as long as usual and won Dr. Bartke a prize presented by the Methuselah Foundation (which rewards developments in life-extension therapies) in 2003.

The Secret to a Long Life Is Conscientiousness

LongevityProjectBK.jpg

Source of book image: online version of the NYT review quoted and cited below.

(p. D3) Cheerfulness, optimism, extroversion and sociability may make life more enjoyable, but they won’t necessarily extend it, Howard S. Friedman and Leslie R. Martin found in a study that covered eight decades. The key traits are prudence and persistence. “The findings clearly revealed that the best childhood personality predictor of longevity was conscientiousness,” they write, “the qualities of a prudent, persistent, well-organized person, like a scientist-professor — somewhat obsessive and not at all carefree.”
. . .
There are three explanations for the dominant role of conscientiousness. The first and most obvious is that conscientious people are more likely to live healthy lifestyles, to not smoke or drink to excess, wear seat belts, follow doctors’ orders and take medication as prescribed. Second, conscientious people tend to find themselves not only in healthier situations but also in healthier relationships: happier marriages, better friendships, healthier work situations.
The third explanation for the link between conscientiousness and longevity is the most intriguing. “We thought it must be something biological,” Dr. Friedman said. “We ruled out every other factor.” He and other researchers found that some people are biologically predisposed to be not only more conscientiousness but also healthier. “Not only do they tend to avoid violent deaths and illnesses linked to smoking and drinking,” they write, “but conscientious individuals are less prone to a whole host of diseases, not just those caused by dangerous habits.” The precise physiological explanation is unknown but seems to have to do with levels of chemicals like serotonin in the brain.
As for optimism, it has its downside. “If you’re cheerful, very optimistic, especially in the face of illness and recovery, if you don’t consider the possibility that you might have setbacks, then those setbacks are harder to deal with,” Dr. Martin said. “If you’re one of those people who think everything’s fine — ‘no need to back up those computer files’ — the stress of failure, because you haven’t been more careful, is harmful. You almost set yourself up for more problems.”

Feds Finally Admit Some Children Harmed by High Fluoridated Water Mandates

FluorisisChart2011-05-19.jpg


WSJ article quoted and cited below.

Back when I was a child, decades ago, my family opposed the fluoridation of public water supplies on the grounds that there might be health risks, and people could individually choose to apply fluoride to their teeth.
Well, now the government is suggesting that too much fluoride can harm children’s teeth, and that the target level for fluoride in the water should be reduced.

(p. A3) The federal government lowered its recommended limit on the amount of fluoride in drinking water for the first time in nearly 50 years, saying that spots on some children’s teeth show they are getting too much of the mineral.

Fluoride has been added to U.S. water supplies since 1945 to prevent tooth decay. Since 1962, the government has recommended adding a range of 0.7 milligrams to 1.2 milligrams per liter.
. . .
A study conducted between 1999 and 2004 by the federal Centers for Disease Control and Prevention found that 41% of children between the ages of 12 and 15 exhibited signs of dental fluorosis, a spotting or streaking on the teeth. That was up from nearly 23% found in a study from 1986 and 1987.
. . .
. . . for years, some groups have called for an end to fluoridation, arguing that it poses serious health dangers, including increased risk of bone fractures and of decreased thyroid function. Friday’s announcement did little to appease such critics.
“The only rational course of action is to stop water fluoridation,” said Paul Connett, executive director of the Fluoride Action Network, a nonprofit advocacy and fluoride-education group

Patients Face Higher Costs and Less Innovation Due to FDA

CongerMartiDiskImplant2011-05-16.jpg“Marti Conger, a business consultant in Benicia, Calif., went to England in October 2009 to get an implant of a new artificial disk for her spine developed by Spinal Kinetics of Sunnyvale, Calif., a short distance from her home.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. B1) Late last year, Biosensors International, a medical device company, shut down its operation in Southern California, which had once housed 90 people, including the company’s top executives and researchers.

The reason, executives say, was that it would take too long to get its new cardiac stent approved by the Food and Drug Administration.
“It’s available all over the world, including Mexico and Canada, but not in the United States,” said the chief executive, Jeffrey B. Jump, an American who runs the company from Switzerland. “We decided, let’s spend our money in China, Brazil, India, Europe.”
. . .
(p. B7) “Ten years from now, we’ll all get on planes and fly somewhere to get treated,” said Jonathan MacQuitty, a Silicon Valley venture capitalist with Abingworth Management.
Marti Conger, a business consultant in Benicia, Calif., already has. She went to England in October 2009 to get an implant of a new artificial disk for her spine developed by Spinal Kinetics of Sunnyvale, Calif.
“Sunnyvale is 40 miles south of my house,” said Ms. Conger, who has become an advocate for faster device approvals in the United States. “I had to go to England to get my surgery.”
. . .
Device companies have been seeking early approval in Europe for years because it is easier. In Europe, a device must be shown to be safe, while in the United States it must also be shown to be effective in treating a disease or condition. And European approvals are handled by third parties, not a powerful central agency like the F.D.A.
But numerous device executives and venture capitalists said the F.D.A. has tightened regulatory oversight in the last couple of years. Not only does it take longer to get approval but it can take months or years to even begin a clinical trial necessary to gain approval.
Disc Dynamics made seven proposals over three years but could not get clearance from the F.D.A. to conduct a trial of its gel for spine repair, said David Stassen, managing partner of Split Rock Partners, a venture firm that backed the company. “It got to the point where the company just ran out of cash,” Mr. Stassen said. Disc Dynamics was shut down last year after an investment of about $65 million.

Mexican Universal Health Care: “There Are No Doctors, No Medicine, No Hospital Beds”

(p. 6) A decade ago, half of all Mexicans had no health insurance at all. Then the country’s Congress passed a bill to ensure health care for every Mexican without access to it. The goal was explicit: universal coverage.

By September, the government expects to have enrolled about 51 million people in the insurance plan it created six years ago — effectively reaching the target, at least on paper.
The big question, critics contend, is whether all those people actually get the health care the government has promised.
. . .
The money goes from the federal government to state governments, depending on how many people each state enrolls. From there, it is up to state governments to spend the money properly so that patients get the promised care.
That, critics say, is the plan’s biggest weakness. State governments have every incentive to register large numbers, but they do not face any accountability for how they spend the money.
“You have people signed up on paper, but there are no doctors, no medicine, no hospital beds,” said Miguel Pulido, the executive director of Fundar, a Mexican watchdog group that has studied the poor southern states of Guerrero and Chiapas.
Mr. Chertorivski acknowledges that getting some states to do their work properly is a problem. “You can’t do a hostile takeover,” he said.
The result is that how Mexicans are treated is very much a function of where they live. Lucila Rivera Díaz, 36, comes from one of the poorest regions in Guerrero. She said doctors there told her to take her mother, who they suspected had liver cancer, for tests in the neighboring state of Morelos.

Nanotechnology Zaps Dangerous Superbug

MRSAcellBeforeNanoZap2011-04-25.jpg “A MRSA cell before treatment with nanoparticles.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. A3) Researchers at International Business Machines Corp. said they developed a tiny drug, called a nanoparticle, that in test-tube experiments showed promise as a weapon against dangerous superbugs that have become resistant to antibiotics.

The company’s researchers, in collaboration with scientists at the Institute of Bioengineering and Nanotechnology, Singapore, said their nanoparticle can target and destroy antibiotic-resistant bacteria–such as the potentially lethal Methicillin-resistant Staphylococcus aureus, or MRSA–without affecting healthy cells.
. . .
IBM, based in Armonk, N.Y., has been working for decades on nanotechnology, which involves engineering atomic-scale particles and electronics. Recently the company has applied those principles–used to create tiny, fast semiconductors–into new areas such as water purification and recyclable plastics. It’s now applying those principles to medicine.
“It turns out that we’ve discovered a lot of ways to control materials at the molecular level as we went through building microelectronic devices,” Dr. Hedrick said.

45% of Mummies Had Heart Disease

“A mummy enters the CT scanner at St. Luke’s Hospital in Kansas City, Mo. It was one of 52 mummies examined for signs of heart disease.” Source of caption and photo: online version of the Omaha World-Herald article quoted and cited below.

(p. 6A) Atherosclerosis — hardening of the arteries — was surpris­ingly widespread during an­cient times, at least among the Egyptian mummies examined by an international team of sci­entists and heart specialists.

Their research, whose re­sults were presented April 3 in New Orleans at the annual meeting of the American Col­lege of Cardiology, found that 45 percent of the mummies they put through CT scans had signs of atherosclerosis.
That raises questions about whether hardening of the arter­ies is the modern disease that many think it is.
“We found it so easily and frequently that it appears to have been common in this soci­ety,” said Randall Thompson, a cardiologist at St. Luke’s Hospi­tal in Kansas City.

The Elite Feel More Important, and Receive More Funding, During Crises

(p. 103) Claims of disastrous decline will he praised in the elite parts of society. Since many crave recognition or rewards from elites, people oblige by producing claims of disastrous decline. More generally, when things really are bad we naturally turn to eminent or powerful people for their advice and succor; when things are fine, the elite classes are of diminished importance to society. Important people like to feel important, and thus are biased toward viewing events in bleak terms. Consider that, during the 1990s, when nearly everything in the United States was trending positive, left-wing leaders as exemplified by the Manhattan chardonnay circuit, and right-wing leaders as exemplified by the Heritage Foundation circuit, slugged it out as though the world was ending: the left claiming religious fanatics were taking over the country, the right claiming the left was destroying the family and opposed to reading of the classics, to name a few totally cooked-up charges of that period. As Orlando Patterson, a Harvard University sociologist, noted in 1998, “It’s astonish-(p. 104)ing how the Washington and New York elites, who benefit so much from the improvement of the United States, are so out of sync with it, endlessly talking about how things are getting worse when the country is clearly improving.”

To those who benefit from bad news, either by fund-raising or increased self-importance, problems are not just problems but crises–the health care crisis, the farm-bill crisis, the tax crisis, the welfare crisis, the litigation crisis, the postage-rate crisis.
