806,000 hip and knee implants were performed in the US in 2007 – that’s double the amount done a decade earlier. However, a 2007 study demonstrates that 7% of Medicare patients who underwent a hip replacement required another replacement hip within seven and a half years. That number, small as it sounds, translates into thousands of patients who eventually need a “do over”. A joint surgery involves risk, pain, convalescence, rehab and medical expenses; no one wants to go through that more than once if necessary.
A National Joint Replacement Registry helps reduce the rate of failed procedures by keeping a database of information that keys in surgeons to problematic implants, and provides insight as to how to avoid mess ups. According to Dr. Daniel Berry, chief of orthopedic surgery at the Mayo Clinic in Rochester, Minn, “Every country that has developed a registry has been able to reduce failure rates significantly.” Sweden is one case in point.
The newly formed American Joint Replacement Registry is still in its nascent stage and has started collecting data. Its goal is to improve the quality, outcomes, and cost-effectiveness of total joint replacement (TJR) surgeries through the achievement of four objectives:
1. Establish an infrastructure and a uniform system for the collecting device information and monitoring outcomes of TJR throughout the U.S.;
2. Identify patients who may need follow-up evaluation thereby increasing patient safety;
3. Create real-time survivorship curve in order to detect poorly performing implants;
4. Establish a uniform system that can be used to define the epidemiology of TJR for outcomes research to improve the quality and outcomes of patient care.
Until we have access to solid facts from the U.S. Registry, there are some proactive steps you can take if you are in the market for a new joint.
– Go with a highly experienced surgeon in a busy hospital; don’t look for the best deal. Ask for recommendations. A 2004 study published in The Journal of Bone and Joint Surgery found that patients receiving knee replacements from doctors who performed more than 50 of the procedures a year had fewer complications than patients whose surgeons did 12 procedures or fewer a year.
A similar trend was documented with hospital volume. Patients at hospitals that performed more than 200 knee replacements a year fared better than patients at hospitals that performed 25 or fewer.
– A joint replacement is not for everyone. Some arthritic problems are better served with medication, and surgery may be too risky for those who have uncontrolled high blood pressure or another serious chronic condition.
– Research the joint implant that your surgeon recommends. Find out how well it has performed in others and if there are known complications. Some implants are somewhat controversial and may cause tissue and bone damage; newer doesn’t necessarily mean better. If the hospital has its own registry, ask to review the data.
– Educate yourself as to what the surgery entails. The American Academy of Orthopaedic Surgeon’s patient information Web site, orthoinfo.org is very helpful.
– Prepare your recovery in advance. Arrange for the necessary support upon your return home, and make sure you have all the help you need. It is crucial not to overexert yourself during your initial healing period.
As we work with administrators to help navigate the world of Long Term Care it is hard not to be hyper-aware of our own mortality and the eventuality that we, too, are likely to reach a point where we will need some level of assistance in getting through the tasks of day-to-day living. This awareness, combined with our mission to be a resource for those who serve the aging, means that our antennae are up for any news related to maintaining our bodies and minds well into our twilight years!
A New York Times review of the new book The Secret Life of the Grown-Up Brain caught my eye a week or so ago, and the author, Barbara Straunch, had some interesting insights to share relative to what middle-aged brains are actually good at, and how to keep our brains functioning well into the future.
- Our brains are still growing and developing far into adulthood. Although we do have some compromises in short term memory (Where are my keys anyway? And what is your name?), the middle-aged brain is actually better in many ways than at any other point in our lives.
- Logic, creativity and social skills are all at a high point during those middle years. Although you might not remember the name of the person to whom you are speaking, you will be an excellent judge of his character.
- We do not, as previously thought, actually lose brain cells as we age.
- Exercise and diet recommendations that benefit your heart are also likely to benefit the health of your brain. Exercise in particular can actually help strengthen and grow your brain. So get out there and start moving!
- Although there are benefits to making your brain work hard, crossword puzzles and learning a foreign language hold no particular magic powers in terms of maintaining the health of your brain. Partaking in vigorous debates on subjects of interest can be just as helpful, so unless you just love the Sunday Times crossword puzzle, you can stop doing it!
- Meeting and engaging with people is healthy for your brain, and your mood!
It is so refreshing to hear that middle age is not necessarily the beginning of a slow slide into senility. Staying engaged and active in life, both in terms of intellectual pursuits and social involvement, seems to be key to keeping your gray matter from graying.
I am hopeful that by maintaining an active life filled with fulfilling relationships, creative pursuits and lively conversation, I can remain one less consumer of Long Term Care services in New York!
According to Jarett Berry, a cardiologist at University of Texas Southwestern Medical Center in Dallas, one must be vigilant about keeping physically active. Yes, in what they used to call “Middle Age.” Wasn’t that the time we thought would be a little slower, a tad less “vigorous,” an entitlement to ease up a bit? Not if you want to hit 85 says the good Dr. “If you are fit in mid-life, you double your chance of surviving to 85.”
Dr. Berry’s findings, presented last week in San Francisco at the American Heart Association’s Annual Epidemiology and Prevention Conference, are based on an analysis of 1,765 men and women who had physical examinations performed during the 1970’s and 1980’s at the Cooper Institute, the Dallas-based birthplace of the aerobics movement. Put another way: If you’re not fit in your 50’s, your projected life span “is eight years shorter than if you are fit,” Dr. Berry says.
So regular exercise is the most cogent weapon we have to ward off illness and fight disease- as it results in lower blood pressure, healthier cholesterol, and lower blood sugar.
Rest assured… there is a silver lining to all this before you start jogging, digging ditches, or playing singles tennis: Studies also indicate that exercise’s greatest impact occurs when individuals move from a sedentary lifestyle to embarking on regular moderate exercise regimens.
That’s encouraging. You go, Girl!
With the number of U.S. seniors with Alzheimer’s skyrocketing, much research is underway to determine how to stave off this mental deterioration, keeping people physically and mentally sound as they age.
A recent report in the December Journals of Gerontology: Medical Sciences found that older women who volunteered for Experience Corps – tutoring elementary school children, had increased brain activity in regions important to cognitive function after a period of six months.
What was exciting about these results, is that it shows a direct correlation between community-based programs and improved cognitive functions. Until now, much study has been done on the brain-boosting power of cognitive, physical and social leisure activities, but little was known about the effectiveness of community-based service.
“This finding is best captured by a personal observation from one of the volunteers, who stated that ‘it [Experience Corps] removed the cobwebs from my brain.” wrote Michelle C. Carlson, of Johns Hopkins Bloomberg School of Public Health.
The seventeen women enrolled in this study were low-income African-Americans with little education, aged 65 and older, and deemed high-risk for cognitive declines, based on a mental state evaluation. Eight of the women actually participated in the tutoring program in Baltimore elementary schools, while the other nine served as the control.
Via functional magnetic resonance imaging, researchers assessed neural activity in the brain prior to the volunteering experience, and again after six months. Based on the fMRI assessment, the women who actively participated in Experience Corps saw improvements in mental function compared with those in the control group.
There you have it, doing your civic duty and assisting others is highly rewarding to all participants. These meaningful activities seem to be more enriching than highly stimulating activities performed alone

Relax actively. That’s the advice of researchers to the retired and the elderly. Not only is it beneficial for your heart, it’s beneficial for your mind.
This news is the conclusion of numerous studies concerning how exercise affects the brain. Exercise causes a chain of reactions that release chemicals into the bloodstream, while regular aerobic workouts build up the presence of these chemicals. The results are startling. Far from the usual shrinking that accompanies aging, the brain begins to grow.
Children have flourishing brains that branch out new neurons with an exuberant frequency. The adult brain begins trimming back unused neurons, and some also die on their own. Until these recent studies, scientists believed that these dead neurons could never regrow. Now they know differently.
In a study by Columbia University’s Scott Small and the Salk Institute’s Fred Gage, subjects asked to exercise regularly seemed to sprout new neurons; the more fit they became the more neurons they grew. The neurons appeared in the section of the brain dedicated to learning and memory, one of the first sections to age. “It’s not just a matter of slowing down the aging process,” explained Arthur Kramer, of the University of Illinois. “It’s a matter of reversing it.”
Exercise does more than just grow a bigger brain. A research group at the University of Washington found that people who exercise three or more times a week have a 30% lower risk of developing Alzheimer’s. Nor did the exercise have to be an intense aerobic workout. Lead researcher Dr. Eric Larson said that a 15-minute walk three times a week was enough to reduce the risk. A similar study found that five to six hours of vigorous physical activity each week led to a 40% decrease in risk of developing Parkinson’s Disease.
Scientists don’t know why this happens, and they haven’t yet zeroed in on the best exercises. But until they figure it out, one thing remains clear: being a couch potato is bad for the brain. So move!

Wouldn’t it be nice if you could get the benefits of exercise without expending more energy then swallowing a pill? AICAR, an old drug that has long been recognized for its ability to stimulate the creation of mitochondria, might be the pill for you.
Mitochondria are the powerhouses of the cell, producing the energy that powers our body. Recently, AICAR was administered to mice who were kept sedentary. After a few weeks, the AICAR mice raced regular sedentary mice, and ran 44% farther and 23% longer.
AICAR seems to mimic the effects of aerobic exercise, increasing stamina, but not building strength. It is being investigated as an aid in fighting diabetes and aging, and for uses in heart bypass surgery. Athletes need not apply.
Of course, the fact that AICAR works in mice doesn’t mean it’ll work in humans. Furthermore, it might have unpleasant side effects. And, as many researchers have hastened to point out, it doesn’t mimic all the myriad of benefits a person gets from real movement and exercise, which includes many chemical reactions besides mitochondria.

Dementia isn’t all about aging, studies show. Health in mid-life can have a marked effect on cognitive ability later on.
A British study of 10,308 people, mostly men, followed the subjects from roughly the ages of 35-55 (the study started in 1985) to about 60-75 years (the study ended in 2004).
Coronary heart disease in midlife was found to be linked to lower cognition in later years. In men, heart disease was linked to lower reason, vocabulary, and MMSE scores. In women, it corresponded additionally to lower phonemic and semantic fluency.
The longer the heart disease – meaning, the earlier it was contracted – the greater the drop in cognitive ability over the years. This suggests that heart disease creates an ongoing condition that continuously deteriorates mental function until dementia kicks in.
