IOM Unveils Hot Reads in Time for Summer

In case you’re looking for something more meaningful to read this summer than Fifty Shades of Grey or Abraham Lincoln: Vampire Hunter, The Institute of Medicine has released some dandy reports suitable for reading or for hiding those trashy beach novels.

First up, in May, IOM released Accelerating Progress in Obesity Prevention: Solving the Weight of the Nation. The report focuses on five critical goals for preventing obesity:

  • integrating physical activity into people’s daily lives,
  • making healthy food and beverage options available everywhere,
  • transforming marketing and messages about nutrition and activity,
  • making schools a gateway to healthy weights, and
  • galvanizing employers and health care professionals to support healthy lifestyles.

The committee outlined specific strategies include: requiring at least 60 minutes per day of physical education and activity in schools, industry-wide guidelines on which foods and beverages can be marketed to children and how, expansion of workplace wellness programs, taking full advantage of physicians’ roles to advocate for obesity prevention with patients and in the community, and increasing the availability of lower-calorie, healthier children’s meals in restaurants.

Also in May, IOM published Ethical and Scientific Issues in Studying the Safety of Approved Drugs. In response to the passage of the Food and Drug Administration Act in 2007, the FDA asked the IOM to evaluate scientific and ethical aspects of safety studies for approved drugs. The IOM concluded that the FDA’s current approach to drug oversight in the postmarket setting is not systematic enough and does not ensure that benefits and risks of drugs are assessed consistently over the drug’s life cycle.  “Adopting a regulatory framework that is standardized across all drugs, yet flexible enough to adapt to regulatory decisions of differing complexity, could help make the agency’s decision-making process more predictable, transparent, and proactive. These changes could allow the FDA to better anticipate postapproval research needs and improve drug safety for all Americans.”

Finally, for the ambitious reader, the IOM had just released the discussion paper A CEO Checklist for High-Value Health Care. Despite risking costs, healthcare remains suboptimal in many areas. “To aid and accelerate the system-wide transformation necessary, we have assembled what we are calling “A CEO Checklist for High-Value Care” (the Checklist). The Checklist’s 10 items reflect the strategies that, in our experiences and those of others, have proven effective and essential to improving quality and reducing costs. They describe the foundational, infrastructure, care delivery, and feedback components of a system oriented around value, and represent basic opportunities—indeed obligations—for hospital and health care delivery system CEOs and Boards to improve the value of health care in their institutions.”

The 10 items include:

  • Governance priority—visible and determined leadership by CEO and Board
  • Culture of continuous improvement—commitment to ongoing, real-time learning
  •  IT best practices—automated, reliable information to and from the point of care
  • Evidence protocols—effective, efficient, and consistent care
  • Resource utilization—optimized use of personnel, physical space, and other resources
  • Integrated care—right care, right setting, right providers, right teamwork
  • Shared decision making—patient–clinician collaboration on care plans
  • Targeted services—tailored community and clinic interventions for resource-intensive patients
  • Embedded safeguards—supports and prompts to reduce injury and infection
  • Internal transparency—visible progress in performance, outcomes, and costs

The U.S. Obesity Epidemic and Surging Liver Cancer

If there is one truism that trumps everything else these days about U.S. health, it’s that America is a chubby country that keeps getting fatter.

The consequences seep into every corner of the nation’s medical state, including the surprising fact that obesity and the type 2 diabetes it causes are likely pushing up the incidence of liver cancer—hepatocellular carcinoma—to unprecedented heights.

When I covered Digestive Disease Week in San Diego recently, one of the biggest stories I heard was that U.S. liver-cancer rates tripled from 1975-2007, and that the numbers continued to rise from the mid to the late 2000s. (My full report on this is here).

Granted, factors other than just obesity play into the liver cancer surge, notably the sizable number of Americans infected with either hepatitis B or C virus, and the fact that as they age their risk for developing hepatocellular carcinoma rises.

But new U.S. infections by hepatitis B and C are largely under control these days (although people infected elsewhere continue to emigrate to the United States). The part of the booming liver-cancer story that is by no means under control is the obesity part.

Every time I see a new CDC map for U.S. obesity prevalence, the colors on it keep getting redder and darker (the CDC’s code for higher prevalence rates).

Earlier this year, the CDC reported a 36% obesity prevalence rate for the entire U.S. population–and still on the rise–and just a few weeks ago we heard that obesity among children and adolescents had hit a new high of 17%. With obesity seemingly on an unchanging upward trajectory, one can only wonder what rates of liver cancer it might produce in the future. Obesity carries a special relationship with the liver, and it’s not pretty. Just consider any goose headed to a foie-gras future.

Until now, the evidence linking obesity and liver cancer, and type 2 diabetes and liver cancer has been epidemiologic. Compelling, but just an association. At DDW, a new study provided more observational data on the diabetes-liver cancer link, and while still circumstantial it further supports the notion and also carries an intriguing punchline.

The study, done in Taiwan, examined 97,000 hepatocellular carcinoma patients and 195,000 matched controls. The analysis showed that people with diabetes had a two-fold increased risk for liver cancer compared with those without diabetes. Even more striking, the analysis also showed that people with diabetes treated with the oral hypoglycemic drug metformin had their risk for liver cancer cut in half compared with those not on metformin, and those with diabetes treated with a glitazone drug (such as pioglitazone–Actos) had their risk cut nearly in half.

The best solution would be if people avoided obesity and type 2 diabetes all together. Both conditions cause a lot of medical problems, and this new evidence indicates more strongly than ever before that liver cancer is one of them.

ED Patients Blind to Risks of Being Overweight

American tongues start wagging whenever the latest starlet puts on a few pounds, but we appear loathe to discuss our own ever-increasing waistline.

A study of 453 adults presenting to a Florida ED found that 58.5% of overweight/obese African American and Caucasian men and women feel their weight is not a health issue AND have never discussed their weight with their healthcare provider.

The average BMI in the study was 29.5 kg/m2, mean weight 184 pounds, 61% were female and the average waist circumference an undignified 39.5 inches.

Given those stats, you’d think these patients had gotten an earful from their provider, but not so.

Overall, 38% of all patients reported their weight to be unhealthy, but only 28% recalled being told so by their provider, University of Florida emergency physician Dr. Matthew Ryan reported at the recent meeting of the Society for Academic Emergency Medicine in Chicago.

It’s possible that some physicians may be afraid to bring up weight for fear their patients will scurry off to a “kinder, gentler” provider. Others may simply be short on time. Yet even when docs did start the conversation, some patients just couldn’t make the connection between obesity and health risks.

Among patients told by their provider they were overweight, 77% believe their present weight is damaging to their health, yet 23% still believe their weight is not unhealthy.

Dr. Ryan points out there’s an obvious disconnect between patients’ perceptions of their weight and their actual weight and current health, and suggests that “the first line of action toward confronting the mounting obesity epidemic in the U.S. is clear patient-provider education.”

The chaotic environment of the ED may seem like an unlikely place to help increase patient awareness about weight-related medical issues or to provide weight-loss counseling, but there may just be something to the “Willie Sutton rule” that teaches, not just bankrobbers, but medical students to focus on the obvious.

As part of the study, the investigators also measured the prevalence of obese patients presenting to their ED in order to compare it to state and national prevalence rates. It reached a whopping 38%, towering over the already hefty 26.6% obesity rate reported for the general population in Florida in 2010 by the CDC.

To their knowledge, the authors say no studies have directly measured the obesity prevalence in the ED. Thus, the ED population may be poorly represented in existing national healthcare studies, which are largely community-based. Moreover, the obesity prevalence may be higher than indicated by studies like the CDC’s that rely on self-reported height and weight.

Given the author’s findings in the ED, that’s a very real and chilling possibility.

The research was supported by a University of Florida Clinical and Translational Science Institute grant.  Dr. Ryan reported having no conflicts of interest.

More Docs Are Asking Patients to Exercise

Physicians are getting better at advising adults to exercise.

In 2010, 32.4% of adults in the United States who had seen a physician or other health care professional in the past year had received a recommendation to begin or continue to do exercise or physical activity, up from 22.6% in 2000. At each time point, women were more likely than men to have been advised to exercise.

The findings, published this month as a National Center for Health Statistics Data Brief, come from the National Health Interview Surveys conducted in 2000, 2005, and 2010.

Between 2000 and 2010 the percentage of patients aged 85 and older who received a “get fit” recommendation from a physician nearly doubled from 15.3% to 28.9%. The percentage of patients aged 18-24 years receiving such a recommendation also increased during the same time period, but to a lesser extent (from 10.4% to 16.1%).

The report also found that the percentage of adults with hypertension, cardiovascular disease, cancer, and diabetes who received exercise advice from a physician increased between 2000 and 2010.

“Trends over the past 10 years suggest that the medical community is increasing its efforts to recommend participation in exercise and other physical activity that research has shown to be associated with substantial health benefits,” the report states. “Still, the prevalence of receiving this advice remains well below one-half of U.S. adults and varies substantially across population subgroups.”

Attacking Obesity

The diversity of disciplines represented at the annual meeting of The Obesity Society parallels the reach of the obesity epidemic itself.

Primary care physicians, endocrinologists, pharmacologists, bariatric surgeons, psychiatrists, psychologists, social workers, educators, nutritionists, and food service workers have spent the past five days in Orlando, Fla., wrestling the obesity beast, trying to shed light on why it is so intractable and discussing interventions that may tame it. Following are a few observations from the meeting:

Courtesy of the Rudd Center for Food Policy & Obesity

1. Although obesity in the United States is being attacked full-force from all sides with drugs, surgery, and psychosocial and behavioral interventions, its prevalence is expected to continue to climb as those born in the 1980s (when the obesity epidemic began) age into their “prime years of obesity incidence,” according to data presented by Whitney Robinson, Ph.D. of the University of North Carolina at Chapel Hill. Dr. Robinson and colleagues used height and weight data measured from 1971-2008 in the National Health and Nutrition Examination Survey (NHANES) to quantify cohort effects as a way to estimate obesity trends. They determined that cohorts born in the 1980s had significantly increased obesity risk versus those born in the late 1960s. The cohort effects, which are those not attributable to the additive effects of age and period, for the 1979-1983 and the 1984-1988 birth cohorts relative to the late 1960s cohort were 1.18 and 1.21, respectively.

Although it is well understood that period effects representing widespread environmental influences have driven increases in obesity prevalence, Dr. Robinson reported, “obesity in adults born in the 1980s shows positive cohort effects as well.”  This finding suggests that even if the obesigenic environment stabilizes, obesity prevalence could continue to increase, particularly in the absence of widespread environmental change.

2. Technology is becoming an ubiquitous weapon in the obesity armamentarium, as evidenced by the many presentations focusing on computer-, Internet- and even smart phone-based strategies. For example, in one late-breaking presentation, Kelly H. Webber, Ph.D. and Dr. Stephanie A. Rose of the University of Kentucky, Lexington, described a pilot study comparing the impact of an Internet behavioral weight loss program alone and in combination with portion-controlled food provision. The study demonstrated that the short-term effect of the combination approach was particularly beneficial.

Similarly, Melissa A. Napolitano, Ph.D. of Temple University in Philadelphia presented a pilot trial of a virtual reality-based psycho-educational intervention for modeling weight loss skills. The findings demonstrated short-term success, with outcomes approximating those found in conventional behavioral weight loss programs.

Finally, a comprehensive evaluation of available iPhone apps for weight loss, presented by Penny Deck, a Ph.D. student at Simon Fraser University, demonstrated the considerable variation in the degree to which the applications follow evidence-based recommendations for weight loss. In particular, she noted, “most of the apps demonstrated poor adherence to such recommendations as basing goals on behaviors vs. weight and advocating small sustainable changes.”

All of the technology interventions are still too young to have long-term outcomes data. It is therefore too early to determine whether their short-term efficacy is a function of the interventions themselves or their novelty. In a presentation describing the apparent benefits of a church-based telemedicine weight loss intervention, Gary Foster, Ph.D., of Temple University observed that most behavioral weight loss interventions are effective in the short term, “but what we really need are long-term studies to evaluate their continued efficacy over time.”

3. Anti-obesity prejudice is pervasive in all sectors of society, including among individuals and organizations in positions of influence. In response to a query from an attendee about the FDA’s reluctance to approve amphetamines for weight loss but not for attention deficit disorder, Dr. George Bray, chief of the division of Clinical Obesity and Metabolism at Pennington Biomedical Research Center in Baton Rouge, La., attributed the double standard to the cultural perception that obesity is an aesthetic problem. “ADHD is viewed as a disease, while obesity is perceived to be a moral deficit,” he said.

The cultural stigma is perpetuated by the news media and even by medical professionals through the photographic and video portrayal of overweight people using headless body shots, primarily focusing on unflattering views of the abdomen or lower body, often in sloppy attire and eating unhealthfully, according to Dr. Arya Sharma, chair in obesity research and management at the University of Alberta in Edmonton, Canada.

To counter the prejudice, the Rudd Center for Food Policy and Obesity at Yale University and The Obesity Society have developed a document called Guidelines for the Portrayal of Obese Persons in the Media, which was available in the meeting press room. The Rudd Center also offers a gallery of more positive images that it makes available to the press.

Street Food May Contribute to Obesity. Surprise.

What about the guys selling food on the street? That was the primary research question posed by Dr. Sean Lucan of Albert Einstein College of Medicine in New York and colleagues as part of a study evaluating whether the fare offered by mobile food vendors in New York contributes to an “obesigenic” food environment. Hmm. Did we really need a study to give us the answer?

Courtesy Wikimedia Commons/Totya/Creative Commons License

The team scoured the Bronx looking for mobile food stalls during the summer and fall of 2010, querying the vendors about what they sold, then assessing the health value of the items. “Only 10% of vendors selling prepared food sold any produce,” Dr. Lucan reported in a poster presentation at the annual meeting of the Obesity Society in Orlando.

In addition, low-fat milk and whole grains were “essentially absent” among the 372 food vendors surveyed, he said. Items high in fat, calories, salt, and/or added sugar were plentiful while fruits and vegetables were limited. Of the 28% of vendors offering any fruit or vegetable, one offered a single whole grain item, while all offered multiple prepared and processed foods. The investigators concluded that the overall contribution of street food vendors “may be unhealthy and obesigenic on balance.” Go figure.

A more enlightening study might consider whether consumers would bite if more healthful street food options were available.

Are You Serving Your LGBT Diabetes Patients?

Are most health care providers attuned to the needs of their diabetes patients who are lesbian, gay, bisexual, and transgender (LGBT)? Does it matter? No and yes respectively, according to certified diabetes educator Theresa Garnero.

More than half of medical school curricula include no information about LGBT people, and most multidisciplinary professionals have not received tools to care for LGBT individuals, Ms. Garnero said at the annual meeting of the American Association of Diabetes Educators.

A number of factors that increase the risk for developing diabetes are highly prevalent among people who are LGBT. For example, obesity and polycystic ovary syndrome (PCOS), both strong risk factors for type 2 diabetes, are more common among lesbians than among heterosexual women. Indeed, in one study, PCOS was identified in 38% of lesbians vs. just 14% of heterosexual women.

Antiretroviral drugs used to treat HIV/AIDS often lead to insulin resistance and type 2 diabetes. Men on HIV treatment have four times the risk of diabetes as do HIV-negative men. Moreover, cigarette smoking, alcohol abuse, and illicit drug use, all of which particularly endanger the health of those with diabetes, are frequent behaviors among LGBT individuals.

Depression is common in both LGBT individuals and people with diabetes. Withholding of insulin among closeted LGBT youth with type 1 diabetes could be a suicidal gesture rather than diabulimia.

How many LGB people have diabetes? It’s extremely difficult to obtain statistics – and there are virtually none for transgendered people – but based on self-reported health data, roughly 1.3 million LGB people have diabetes, a number approximately equal to that of type 1 or gestational diabetes, Ms. Garnero said.

So why does it matter? Lack of awareness and presumption of heterosexuality can lead to mistakes that alienate patients, such as lecturing a young lesbian with diabetes about the need for birth control or expressing negative attitudes toward patients who want to bring their same-sex partners to diabetes-education classes.

Importantly, patients who perceive that they can’t be open with their health care provider about sexual orientation may be reluctant to share other health-related information.

“Individuals who approach the health care system are already vulnerable from their illness … Intolerance is the last thing anyone wants when seeking health care. It is certainly not a part of the caring diabetes professional culture,” Ms. Garnero said.

What can the health care provider do? Placing a rainbow flag sticker or nondiscrimination statement that specifically mentions sexual orientation in the waiting room is a simple way providers can let patients know that they are LGBT-friendly. Other helpful information for providers can be found here.

Bottom line, she said: “All people with diabetes deserve the benefit of our expertise and access to ongoing support.”

Obesity, Diabetes are the Epidemics; Is Bariatric Surgery the Cure?

The quick answer to this question is yes, at least for many (as opposed to all) patients, and at least according to the bariatric surgeons I heard and spoke with at their society meeting in mid-June. My take from that meeting was that bariatric surgery is working wonders these days–of course for obesity, but for type 2 diabetes too. It’s remarkably safe, yet way underused. Will that change soon? Is a golden age of bariatric surgery dawning, and will the big, two-headed medical epidemic now rampaging get tamed as a result?

It’s a tall order, but my bet is on bariatric surgery, and there are hints that its long-standing status as the wallflower of surgical interventions may be shifting.

Last March, the International Diabetes Federation issued a position statement on bariatric surgery saying that it should be “considered earlier in the treatment of eligible patients.” The statement called bariatric surgery “an accepted option in people who have type 2 diabetes and a body mass index of 35 kg/m2 or more.” And for patients with a BMI of 30-35 kg/m2 the statement said that bariatric surgery “should be considered an alternative treatment option” for patients inadequately controlled by optimal medical therapy, especially when they also have major cardiovascular disease risk factors.

To someone like me, previously unfamiliar with where bariatric surgery stood these days, some of the facts I gleaned at the meeting were eye-opening. The perioperative mortality rate for laparoscopic gastric bypass surgery (Roux-en-Y), the type of bariatric surgery considered most practical and effective for treating types 2 diabetes by most surgeons I ran into, fell to a rate of 6/10,000 patients treated in 2009 at about 360 U.S. academic medical centers and affiliated hospitals. The non-fatal complication rates and need for repeat hospitalization was also low, placing the risk from bariatric surgery these days squarely in the ranks of many “routine” surgeries, such as hip replacement, appendectomy,  and gallbladder removal for stones. Gastric band placement is safer still, though not as effective for resolving type 2 diabetes.

The diabetes effect from gastric bypass is also impressive. One recent study compared 46 patients with diabetes who underwent laparoscopic gastric bypass at the Gundersen Lutheran Health System in La Crosse, Wis., with 41 matched patients with type 2 diabetes who remained on their standard medical treatment during 2001-2005.  One year after surgery, the average hemoglobin A1c in the surgery patients stood at a normal 5.8%, compared with their average baseline value of 7.4%. Twenty-seven of these 46 (59%) were in full diabetes remission, meaning they were off all diabetes medications and their HbA1c was below 6.0%. In contrast, just 2 of the 41 conventional-treatment patients (5%) went into remission a year after their baseline.

“If there was a pill that achieved remission rates like this and had a safety profile like this and you didn’t offer it to your patients it would be unethical,” said Dr. Shanu N. Kothari, director of the minimally invasive bariatric surgery center at Gundersen and lead author of this study.

Yet bariatric surgery is neglected by most patients–be they just obese or obese with type 2 diabetes–and by their physicians. At the meeting I heard that about 200,000 U.S. bariatric surgeries are done annually now, a scope dwarfed by the number of patients who are candidates.

Why the neglect? Several surgeons at the meeting noted the disconnect between acceptance in the medical community of bariatric surgery relative to just about every other type of medically driven surgery out there.

What’s also striking is that bariatric surgery’s success contrasts with the problems that medical weight loss and maintenance has faced recently. During the past year or so, the Food and Drug Administration has shot down lorcaserin (Lorqess), the combination of phentermine and topiramate (Qnexa) , and another combination, bupropion and naltrexone (Contrave), all because of concerns that these agents might cause cardiovascular adverse events. In contrast, a report at the bariatric surgery meeting showed that all forms of bariatric surgery actually led to significant reductions in cardiovascular disease events as well as increased patient survival.

With medical management of obesity in sorry shape, and lots of evidence building for surgery’s safety and efficacy, the ascendance of a surgical solution to obesity and diabetes may have begun.

AMA House Ends on Sour Note: The Policy & Practice Podcast

The American Medical Association’s House of Delegates meeting wrapped up on Tuesday afternoon, a day ahead of schedule. The delegates touched on a wide range of issues over the four days at the Hyatt Regency in Chicago.  None was more hotly debated than whether the AMA should back the so-called individual mandate that’s a central tenet of the Affordable Care Act.

AMA delegates at work. By Alicia Ault

While much time and energy was devoted to that topic, delegates also discussed many public health, practice management and payment issues.  The nation’s obesity epidemic was addressed in many resolutions.  Pediatricians and medical students pushed for having the AMA take a strong stand on fast food, competitive eating, and physical education.

The annual meeting generally showcases the diversity of opinions among the nation’s physicians and among the various medical specialties that make up the House of Delegates. In the end, the policies that are adopted are supposed to reflect some kind of consensus forged out of those many voices.

But perhaps more than any year in the past, it was clear as the meeting ended that the AMA is struggling to maintain a consensus.  Many state delegations complained of declining membership, which they said was directly related to dissatisfaction with how the AMA was representing them.

Take a listen to our final wrap-up podcast on the meeting proceedings.

And tell us whether you think the AMA continues to represent your voice in medicine.

Good Fat: It’s Not Just for Breakfast Anymore

Image courtesy of Flickr user WordRidden (CC)

For years, we’ve been hit over the head with messages about good fat and bad fat.  Let me rephrase that. For years, we’ve been hit over the head with messages about good and bad dietary fat.  It’s time for mono-unsaturated olive oil to make room for brown adipose tissue — good biologic fat.

Fat in the body — aka adipose tissue — appears to come in two colors — white and brown — and it may not entirely be inappropriate to think of these as bad and good fats respectively. I was able to listen in on a very interesting talk about brown adipose tissue today by Dr. Aaron M. Cypress  at Endo 2001 in Boston [OR11-6].

In short, brown adipose tissue is found primarily in the scapular region in humans and deposition of it seems to increase with increasing depth — findings that are based on surgical resection of this adipose tissue in 10 patients undergoing neck surgery.  In other words, more brown adipose tissue is found in the longus colli and carotid sheath than in the prevertebral, subplatysmal, and subcutaneous depots.

Brown adipose tissue can expend energy via thermogenesis, a process that is regulated by the tissue-specific mitochondrial inner-membrane protein uncoupling protein-1 (UCP1). In fact, the researchers looked specifically at oxygen consumption and found that compared with undifferentiated cells, adipocytes found in brown fat had basal and maximally stimulated oxygen consumption rates that were 3.5- and 6.5-fold higher, respectively.

So, it makes sense that more brown adipose tissue is found in thinner people. While it’s way too early to tell, the ability to produce more brown adipose tissue in the body could increase metabolism and maybe increase weight loss — of slacker white adipose tissue.
