Medpagetoday.com REPORTS HERE that "community-based weight-loss programs have not been shown to be effective at reducing the incidence of diabetes, so implementing a national program would likely be money down the drain, a diabetes expert said."

"Richard Kahn, PhD, who was the chief scientific and medical officer of the American Diabetes Association for nearly 25 years, delivered remarks to public health advocates and diabetes researchers at [a symposium recently] where his remarks stood in stark contrast to the "prevention works" message of the event's other speakers."

"He told those in attendance -- some of whom are involved in community-based weight-loss interventions -- that 'community programs are ineffective at achieving weight loss.'"

"Kahn …. said that just sustaining significant weight loss, even with intensive dieting, exercise, and coaching, 'requires near-heroic measures' in the face of a 'very hostile food environment.'"

"He outlined his views in a paper published in the January edition of Health Affairs, in which he wrote that there are two ways to dramatically reduce the toll of diabetes: One is to detect diabetes early and then treat it so effectively that complications from the disease are practically zero. The other is to prevent diabetes before it even happens."

"In sum, to date, we have not seen a demonstration of any program that results in a clinically meaningful weight loss that can be maintained for more than two to three years in the great majority of participants and at a low cost," Kahn wrote.

"Kahn's remarks preceded those of Kenneth Thorpe, of Emory University, who outlined how the healthcare reform law laid the groundwork for a national, community-based diabetes prevention strategy modeled on the Diabetes Prevention Program. Kahn said that would be a waste of money."

"Kahn said that there are too many unanswered questions about how weight loss works that must be answered before a national program would ever succeed in preventing diabetes in the long term."

"He suggested "painful policies" as the solution -- such as raising the price of all food except for fruits and vegetables, and offering financial incentives to people who can keep weight off, while penalizing overweight people with higher insurance premiums."

"He acknowledged those aggressive policies likely would be unpopular among members of Congress and doctors."

"While we wait for the time when lifestyle modification becomes practical, we might be better served by focusing more attention on improving our understanding of the processes that affect energy intake and expenditure and improving the medical management of diabetes," Kahn wrote.

"Those medical management strategies include making an early diagnosis and administering 'proven treatments that have been shown to reduce complications of diabetes and extend life,' he said."

"He added that the best doctors can offer right now is to suggest to overweight patients that losing 4% body weight and keeping it off can reduce the risk for serious complications of diabetes by 15% to 20%."

Clinical Trial Data Should Be Open for Review

Published 04/30/2012 - 3:14 p.m. CDT

Original clinical study reports, which contain far more detail than published randomized trials, should be made available to independent researchers seeking to verify efficacy and safety claims.

In support of this argument, the history of the influenza antiviral oseltamivir (Tamiflu), which was approved by the FDA in 1999, was cited. The widespread belief in oseltamivir's efficacy, was based on a meta-analysis of 10 trials conducted by the manufacturer prior to licensure. But the authors pointed out that the FDA, which was aware of these clinical trials, concluded that oseltamivir had not been shown to reduce complications and required a statement on the drug's label to that effect. Moreover, oseltamivir was not given an FDA indication for prevention of spread of influenza.

To this, [authors] commented, "If FDA is right, the drug's effectiveness may be no better than aspirin or acetaminophen.'"

A group of Democratic senators has introduced a bill that would allow people to sue generic drugmakers over failing to update their drug labels to include all known risks. The bill is meant to counter last year's Supreme Court decision in a generic drug dispute.

When the American Board of Internal Medicine Foundation published its list of 45 overused tests and procedures that physicians and patients should think twice about, it did so with the caveat that these aren’t things doctors should never do — nor are they actions that should never be covered by public and private insurers.

The Choosing Wisely campaign was sparked by a 2010 article that prompted the National Physicians Alliance to publish a list of overused tests and procedures in primary care. The ABIM Foundation wanted to spread the idea to as many medical specialties as possible. The ABIM Foundation recruited nearly a dozen consumer groups, including Consumer Reports, to help disseminate the list.

Regulators on both sides of the Atlantic were slow to inform patients and their doctors about problems with metal-on-metal hip implants and relied on industry officials and consultants in crafting their responses.

Complications included high failure rates and possible systemic effects from elevated metal ion levels in the blood. An advisory has been issued to surgeons, telling them that patients who have received metal-on-metal implants should have annual checkups for life. The evaluations should include testing for metal ions in the blood as well as for clinical symptoms of device failure.

Home is Where the practice is

Published 04/25/2012 - 2:25 p.m. CDT

Historically, many physicians worked in a living space with a medical practice area. That slowly fell out of favor in the 1950s, when more and more physicians set up separate offices or worked in hospitals.

The home-based medical practice currently is something of an oddity, but some physicians have managed to establish one that meets the standards of a commercial space. Setting up a home-based practice is like setting up an office, with a few complications.

Twenty thousand physicians in four Midwest states received a glimpse into their financial future last month. Landing in their email inboxes were links to reports from Medicare showing the amount their patients cost on average as well as the quality of the care they provided. The reports also showed how Medicare spending on each doctor's patients compared with their local peers in Kansas, Iowa, Missouri and Nebraska.

The "resource use" reports, which Medicare plans to eventually provide to doctors nationwide, are one of the most visible phases of the government's effort to figure out how to enact a complex, delicate, and little-noticed provision of the 2010 healthcare law: paying more to doctors who provide quality care at lower cost to Medicare, and reducing payments to physicians who run up Medicare's costs without better results.

"You don’t have to look very far to see the perfect storm developing in our nation’s health care system. With the combination of skyrocketing health insurance premiums, an aging population average, an obesity epidemic, staggering health insurance deductibles, a rapidly climbing incidence of diabetes, a looming doctor shortage, and a record breaking budget deficit … Alan Greenspan said 'The greatest threat to the economy is healthcare.' Our government’s attempt to tweak the system is equivalent to putting up a tent in a hurricane. … The truth is that we won’t stop being sick until we stop making ourselves sick. The ultimate solution is that we need more self-care not more health care."

What Limits?

At this point in the history of mankind, we have been conditioned to abhor symptoms of any kind. Headaches, sneezing, coughing, colds, allergies, pain, infections, hypertension, etc., are no longer tolerated as a part of the process of living. Rather than look into the mechanisms that may be causing these symptoms, we are reaching for the medicine that will suppress them. In so doing, we may feel better, but we now have no motive to look at causes and correct for the issues that may be impairing our health, thus increasing our "need" for more medications over time.

Without the "gold standard" double blind, placebo controlled study there can be no FDA approval of a new drug. So let's look at this approval process more closely.
