It is risky.
Stay fresh. Avoid repeating yourself. Don’t rant. Never preach. These would be the ‘rules’ of supposedly good blogs.
And, of course, doctors that dare to take a stance on health issues risk being perceived as pretentious. I get this.
So it is with trepidation that I write a follow-up to last week’s CW post about right ventricular damage immediately after an extreme race effort. Notwithstanding the pompousness concern, I also wish to avoid being labeled anti-exercise. Few believe more strongly in the healing powers of exercise.
But last Wednesday’s comments (both on the blog, Facebook and here on Dr. Val Jones’ BetterHealth blog) were just too good to let rest.
On the assessment of studies: Read more »

When you sit quietly, your heart slips into the slower, steady pace known as your resting heart rate. A new study suggests that an increase in this rate over time may be a signal of heart trouble ahead.
Your heart rate changes from minute to minute. It depends on whether you are standing up or lying down, moving around or sitting still, stressed or relaxed. Your resting heart rate, though, tends to be stable from day to day. The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high.
Many factors influence resting heart rate. Genes play a role. Aging tends to speed it up. Regular exercise tends to slow it down. (In his prime, champion cyclist Lance Armstrong had a resting heart rate of just 32 beats per minute.) Stress, medications, and medical conditions also influence the heart rate.
In today’s Journal of the American Medical Association, researchers from Norway report Read more »

Severe osteoarthritis of the hands
One of my patients came to see me today with severe right knee pain. This is not a new problem, and in fact, we have been dealing with flare ups of her osteoarthritis for years. It mainly affects her knees and hands and today her right knee was swollen and felt like the “bone was rubbing together” with each step. She could hardly walk because of the pain.
Osteoarthritis is also known as degenerative arthritis and it is one of the most common maladies of aging joints, affecting millions of people. The cartilage in joints wears down and inflammation causes the bones to build up spurs and small micro tears. It affects women more than men and the cause is unknown. There are likely genetic factors as it tends to run in families. Arthritis can occur in any joint but the most common are the fingers, wrists, hips, neck and spine and knees. Stiffness (especially in the morning) and pain are the main symptoms that limit mobility.

Health care facilities should take five steps to ensure staff aren’t becoming sleep fatigued, according to a Sentinel Event Alert from The Joint Commission.
Shift length and work schedules impact job performance, and in health care, that means patient safety, the alert stated. A study of 393 nurses over more than 5,300 shifts showed that nurses who work shifts of 12.5 hours or longer are three times more likely to make an error in patient care.
Furthermore, residents who work traditional schedules with recurrent 24-hour shifts:
–make 36 percent more serious preventable adverse events than individuals who work fewer than 16 consecutive hours,
–make five times as many serious diagnostic errors,
–have twice as many Read more »

Good vibrations may work for dancing on the beach or for romance, but they don’t seem to do much to strengthen bones.
Results of a clinical trial published in the Annals of Internal Medicine showed that older women who stood on a vibrating platform for 20 minutes a day experienced just as much bone loss over the course of the year-long trial as women who didn’t use the platform.
The results are a disappointment for older women and men looking to strengthen their bones without exercising, not to mention to the companies that have sprung up to sell whole-body vibration platforms as an easy way to halt osteoporosis, the age-related loss of bone.
The idea behind whole-body vibration makes sense. Like walking, running, and other weight-bearing physical activities, whole-body vibration Read more »
