Need Another Reason Not To Trust What You Read On The Dr. Oz Show Website?



This past Monday, I wrote a blog about the wastefulness of the NMR LipoProfile test recommended by Dr. Mark Hyman during his PBS appearance (and on his website and I suspect in his new book, etc.). He emphatically advocated for the test because he felt that it was an essential tool to identify people at risk for heart attacks. I opined that it was another expensive test expected to provide little additional information for most people.

Alas, along comes a new study that merits attention. According to the study, performed by John Danesh, FRCP, of the University of Cambridge in England, and colleagues belonging to the Emerging Risk Factors Collaboration, there was only slight improvements in cardiovascular risk prediction gained by adding more blood lipid-related markers to conventional factors. In fact, fewer than 5% of individuals would have their risk classifications changed by including such new markers.

According to the researchers, adding more lipid markers to the risk prediction equation brought, at best, only "slight improvement." The research, published in the June 20 issue of the Journal of the American Medical Association, showed that replacing the standard blood tests used today to determine cholesterol levels and cardiac risk markers with these new lipoprotein-associated factors reduced the accuracy of risk prediction.

In practical terms, this study showed it would be necessary to test from 800 to 4,500 individuals for these lipoprotein markers in order to prevent one major cardiovascular event over 10 years. Now that sure seems like a waste of time and money because even if you test positive, it doesn't assure that you will do anything different in terms of lifestyle or treatment. Even if you add a statin, there is no guarantee it will prevent a heart attack because plenty of people who take statins still have heart attacks. The key to good heart health remains lifestyle and you should live a healthy one regardless of what a doctor or diagnostic test tells you.


The NMR LipoProfile offers three case studies to support their product. Not surprising that the first case study, described as an overweight man, was found to be at greater risk of having a major cardiovascular event based on the test. Duh! Being overweight is clearly a risk factor and you don't need an extra blood test for confirmation.

The take-away here is the usual one. Don't wait for blood tests and diagnoses to force you to take stock of your life and make the changes that will both improve the quality of your life today and your enjoyment of life for years to come. Remember, the longer you live, the healthier you've been.

So once again, I searched the Dr. Oz website to see what it had to say on this matter and of course, there is a posted article written by Dr. Hyman strongly supporting this test.  Imagine that?

Surprise! You're Dead!

A number of my blogs evolve around weight and for good reason. A new study shows that carrying too much weight in the belly -- having an apple shape -- may increase the risk of sudden cardiac death.

Researchers at the University of Minnesota and the VA Medical Center in Minneapolis showed in a cohort study (an observational study that includes an analysis of risk factors and follows a group of people who do not have the disease, and uses correlations to determine the absolute risk of subjects achieving a particular outcome) that the risk of sudden cardiac death increased along with waist-to-hip ratio (WHR).

Here are two graphics to illustrate how one measure WHR.


Measurement of waist hip ratio: In a lean person (above, left), the waist can be measured at its narrowest point, while for a person with convex waist (above, right), it may be measured at about one inch above the navel. The hip is measured at its widest portion of the buttocks at left, and at the great trochanters (part of your femur that protrudes) at right.


According to Dr. Selcuk Adabag, the lead researcher, the WHR, when it comes to the risk for sudden death, was the greatest determinant, ranking even higher than body mass index and waist circumference.

The general rule of thumb for WHR is lower numbers are better.

A WHR of 0.7 for women and 0.9 for men has been shown to correlate strongly with general health and fertility. Women within the 0.7 range have optimal levels of estrogen and are less susceptible to major diseases such as diabetes, cardiovascular disorders and ovarian cancers. Men with WHRs around 0.9, similarly, have been shown to be more healthy and fertile with less prostate and testicular cancer.


The study showed that for individuals in the top quintile of waist-to-hip ratio (0.97 and higher for women and 1.01 and higher for men), the risk of sudden cardiac death was a relative 40% greater  compared with those in the lowest quintile (less than 0.82 for women and less than 0.92 for men).

The lead researcher speculates that the reason for this correlation may have to do with the inflammatory markers produced by abdominal fat. Those markers result in fibrosis in the heart muscle, which could ultimately lead to arrhythmias and sudden cardiac death. Abdominal fat is composed of the more harmful white fat cells.

So if you didn't have enough reasons, motivation, incentives until now to lose weight and get into shape, maybe avoiding sudden death may help?


Here's a WHR calculator so you can calculate your own WHR:

Better Than The Alternative

It's often been said that laughter is the best medicine. Humor can also be a great way to communicate bad news in a less offensive manner. I love this cartoon because it really summarizes the reality of the situation for people who live sedentary lifestyles or hardly exercise.

Study after study now shows the dramatic impact that moderate physical activity has on your health. It reduces heart attacks and strokes, improves cognitive function and memory, alleviates depression, prevents and reduces the consequences of diabetes, etc.  The flip side is that lack of exercise increases your risk for osteoporosis and dementia. Bad things happen to people who don't move!

So folks, what are you waiting for? If you don't like gyms, find a hobby that requires physical exertion. Take steps, park far away from your destination, mow the lawn, wash the car, wash it again, whatever you do just keep moving. Get up, get out, and live the one life you have to the fullest.



 You may find this cartoon amusing, but don't let it be you. 
You are only fooling yourself by pretending to exercise.
A word to the wise should be sufficient.

Thoughts Are Not Facts


It is very hard to lose an argument in your own mind. That’s because there is no one to successfully argue the other side. It is not possible to live and not be exposed to events that are likely to cause stress. These events can include changing jobs, buying a home or car, getting married, having a child, losing a friend or relative, etc. Nevertheless, most people adapt to these stresses well and continue to lead useful lives. Some do not and the stress can become debilitating and disease promoting. Why? There are a number of reasons why each person reacts to stress differently. For most it is the contexts of which the stress occurs and other factors that mitigate or dissipate that stress. The key is not to see the source of the stress as the final arbiter.
When I was a third year medical student at New York University, I was assigned to the Bellevue Hospital Psychiatric Ward as part of my psychiatry rotation. One day, I was asked to process the admission of a man, whom I will call John, who was in his late-twenties, who presented himself to the emergency room as being depressed and suicidal. Accordingly, he was admitted to the hospital for a period of observation. When I did my admission evaluation with him, I asked him why he was depressed. His response caught me off guard and still resonates with me today, some 30 years later. He responded, “I always get screwed.” My initial reaction was that he was exaggerating but that he nevertheless believed it to be true. 
I probed deeper why he felt that way and he simply responded that everything went wrong for him and he was very depressed and wanted to kill himself.  I hoped we could do something for him but I wasn’t sure as a mere third year medical student how one deals with such a predicament. Over the ensuing few days, John underwent psychiatric counseling but still seemed to remain fairly depressed.  After about three days, he summarily informed me that he wished to go home. I dutifully advised the attending physician who felt that John was not ready. The concern was that depressed patients who contemplate suicide are more likely to perform the act once they are more energetic. Therefore, if John was really feeling less depressed, then he was in a particularly dangerous zone. When I told John the doctor did not feel it was time to go home just yet, John became quite agitated, arguing that he had brought himself to the hospital and that he now felt better and was insisting on going home. There was little I could do to assuage John who became increasing petulant. I went back to the attending physician and explained John’s reaction and the doctor remained steadfast in his opinion that John was not ready to be released. Over the next 24 hours whenever John and I spoke, he repeatedly expressed his growing anger about the doctor refusing to let him go home.
After a day or so, the doctor relented and agreed to let John go if he signed a form releasing the hospital of any liability for his medically ill-advised release. John angrily signed and I was asked to fetch John’s street cloths which the hospital had taken into storage. However, when I tried to do so, I was informed that John’s leather coat had gone missing.  I was afraid to tell John because of his now constant overtly manifested anger that he was without a coat in the middle of winter because the hospital had either misplaced it or had allowed it to be stolen.  Sheepishly, I approached John with the bad news expecting him to blow up at me. Then something eerily memorable happened. I told John and he did not react. I thought perhaps he had not heard or understood me and so I repeated myself. Again, he did not react. Finally, I asked John why was he not reacting and he responded, “I told you. I always get screwed.”
Is it possible that some people truly experience more than their share of bad luck? Is life for some a Greek tragedy where fate determines how they ping pong from one misfortune to another?
John thought so, but he was wrong. There is always a certain amount of predetermination in our lives. We can’t control who our parents are and the nature of the environment they create for us, including who we get for siblings. We can’t control the level of affluence we are born into and how that determines how we live, where we live, and what role money plays in our lives. We can’t control if we are born during a peaceful time or during a threatening war.  We can’t redo our childhoods regardless of its influences.
So what can we control? Just about everything else. Even though we may have certain genetic predispositions towards particular diseases, our lifestyle will to a great extent, scientists say 70%, will determine whether we develop chronic diseases like diabetes, heart disease, and cancer, the leading killer of Americans.  We may not be able to choose relatives, but we can to a great extent choose friends and significant others.  Louis Pasteur once said, that “chance favors the prepared mind.” While he was referring to the field of observation, his words ring true for virtually everything in our lives.
My older patients often tell me of aches and pains they suffer. Once I determine that the cause is not serious, I tell them the following. Life is full of aches and pains. It is what makes us feel alive. We can become victims and captives of such nuisances or we can ignore them and live our lives to the fullest. The twists and turns in our lives is what gives life color and flavoring. We can wallow about things that didn’t quite work out the way we wished. Or we can recognize that life may not be perfect but it doesn’t need to be to still be worth living and enjoyable.
 Two personal anecdotes bear evidence to the truth of these statements. One involved my first health care service company which I had founded with investment from others. The investors proved to be meddlers and I spent much of my waking time complaining about them rather than doing something about it. I thought I was stuck. Then one day after complaining about my predicament as had become my norm to an almost stranger (a friend of a friend), I got a wake-up call when he responded that I “sounded pathetic.” It was a rude awakening to say the least. I did not see myself as a whining, pathetic person, but that is what I had become. I had invested too much time and energy in what was wrong as opposed to in finding solutions. Those words changed my perspective and I took action that ultimately made everyone happy, including my investors.
A second anecdote took place more recently. Having grown up lower middle-class where money always factored into limitations and issues, I always thought that selling my company some day for enough money that would allow me to retire would be the highlight of my life. Little did I know the truth, but I found out. About three years ago, I retired after selling my company and I began to wallow in self-pity that I now longer had purpose in life. I had money, the freedom to pursue any hobby or activity, but yet I was miserable. I had always wanted to get more physically fit but I could not find the motivation to do so. I thought that if I only ran my old company again, all would be well. Well I got the opportunity and that reminded me why I sold it in the first place.  It was unfulfilling and I realized that my though process was flawed. It became clear to me that no external factor would be the genesis of my ultimate happiness.  I came to appreciate that happiness, satisfaction, and wellbeing had to be generated from within. Over the past year, I have discovered what it takes to be happy and healthy. It takes finding ways to help others. It takes finding meaning and pleasure in whatever we do whenever we do it. It takes being thankful for what we have and blocking out what we don’t need. It takes nurturing relationships with family, friends and strangers alike.  It takes realizing that “thoughts are not facts” and to spend less time thinking about what will make me happy and more time practicing it.
So if you want to focus on what is wrong in your life, no one can stop you. But that would be a shame because you would miss out on all the ways to find true happiness many of which cost nothing but a new perspective.
