Obesity Harms 'Later Brain Skill'


A Korean study suggests that being obese at a later stage in life increases one’s chances of having a brain decline. The study was done on 250 people between the age group of 60 and 70 with a high BMI or Body Mass Index. The seniors scored poor marks in cognitive tests. The research was published in the journal Age and Ageing.

The study has successfully established the connection between an excess of body fat and brain function. It also pointed out that lifestyle changes could help make a big difference in the brain function.

The participants of the study underwent BMI calculation, scan of fat stored in the abdomen, mental test and waist circumference measurements. The results showed that high BMI and high levels of BMI was linked to poor cognitive performances in the adults, who were aged between 60 and 70.  In individuals above 70, a high level of any of the three factors had no link to cognitive performance.

The researchers expressed a lack of information with regards to the participants developing dementia, but are sure of the fat’s contribution to brain decline. The doctors, who helped conduct the study, said that the impact of weight on the head can be kept in control or at bay by way of exercising regularly, checking blood pressure constantly and checking the cholesterol levels in the body.

As per several researches, at least one in three people over 65 die of dementia though there are things that a person can do to avoid the risk of developing it. The research also indentified the prevention of possible cognitive decline or even dementia by preventing obesity, particularly central obesity.

When Doctors Feel Pain After a Medical Mistake


Dr. David Ring, an associate professor at Harvard Medical School and board certified orthopedic and hand surgeon, once performed the wrong surgery on a patient’s finger. Ring quickly noticed and fixed his mistake, but it was one of the worst experiences of his life, he told ProPublica reporter Marshall Allen in a 2011 interview.

Sometimes doctors or nurses who cause harm to a patient are the perpetrators: They’re careless, negligent, taking on too many cases because they’re greedy, sloppy or incompetent. But often this is not the case. A well-meaning, expertly-trained provider makes an honest error and feels deep remorse.

Plus, there are often extenuating circumstances that contribute to the mistake. In Ring’s case, a series of events contributed to confusion in the operating room that day. As Allen noted:

• The nurse marked the correct arm, but not the incision site.
• Surgeons were behind schedule, so people were stressed.
• The nurse who prepped the patient for surgery wasn’t present for the procedure, because the patient had been moved to a different operating room.
• The nursing team changed in the middle of the procedure.

In these cases, health care providers, like Ring, are sometimes called the “second victim” of medical mistakes. The term recognizes that being part of an error also takes an emotional and psychological toll on the provider. According to Susan D. Scott, a registered nurse and patient safety coordinator at the University of Missouri Health Care, providers have described, in published anecdotes, “powerful feelings of guilt, incompetence, or inadequacy:” feelings that can affect performance and, in some cases, have destroyed careers.

Members of ProPublica’s Patient Harm Community have criticized the term “second victim.” Debra Van Putten called it “deeply offensive and insensitive to the patient community.” Bart Windrum said, “I actually almost abhor the phrase “second victim” describing providers. I understand its impetus, it’s just wholly inaccurate because the family members are the 2nd victims. Providers are at best 3rd victims.”

Many providers stay quiet about errors, which complicates the issue. Some fear a ruined reputation. Some are wary of bullying from colleagues. Some feel pressure from hospital lawyers and risk managers not to admit to mistakes.

But Wu is among those who believe that recognizing the phenomenon and changing medicine’s culture of silence could help doctors heal and benefit patients, too.

“If people are consistently beaten up when there's a bad outcome, you create a climate in which no one talks about anything,” Wu told Health Leaders Media’s Cheryl Clark, “and a conspiracy of silence leads to mistakes being repeated."

Brian Goldman, an emergency room physician in Toronto, echoed Wu’s thoughts in a TED talk in November 2011: “If I can’t come true and talk about my mistakes, how can I share it with my colleagues? How can I teach them about what I did, so they don’t do the same thing?”  

Doug Wojcieszak, a member of ProPublica’s Patient Harm Community, also believes transparency can help reduce lawsuits over medical errors. Wojcieszak’s brother died after a mistake in 1998. Now, his organization, SorryWorks!,encourages and trains health care professionals to rapidly disclose errors, conduct independent reviews and, if necessary, apologize and negotiate financial compensation with patients outside of the courts. The University of Illinois at Chicago Medical Center has experimented with disclosure as part of a program Allen wrote about three years ago.

Wojcieszak said providers have also told him that disclosure is one of the best ways to aid personal healing and learn from mistakes. “The organizations that are really good at this will tell you that the biggest benefit is patient safety,” he said. “When we own our mistakes, we have a chance to learn.”

Practicing Tai Chi Reduces Falls in Stroke Survivors

Those who suffer from a stroke fall seven times more each year than healthy adults, causing fractures and decreasing mobility.  Now, new research is suggesting that the stroke survivors who practice Tai Chi experience less falls when compared to survivors who receive usual care or participate in a national fitness program for Medicare-eligible adults called SilverSneakers. 

Tai Chi is an ancient Chinese martial art that includes physical movements, relaxed breathing, and mental concentration.  Study participants practiced Yang-style Tai Chi, the most popular of the five styles that are used in the United States because of the emphasis on physical and psychosocial benefits.

"Learning how to find and maintain your balance after a stroke is a challenge.  Tai Chi is effective in improving both static and dynamic balance, which is important to prevent falls. Tai Chi is readily available in most U.S. cities and is relatively inexpensive,” Ruth E. Taylor-Piliae, PhD, RN, the study's principal investigator and assistant professor at the University of Arizona College of Nursing in Tucson, AZ, was quoted as saying.

Researchers examined 89 stroke survivors, mostly those who had ischemic strokes on average three years prior to beginning the study, for a randomized prospective study.  Study participants were on average 70 years old, 46% were women, most of them were Caucasian, college educated, and lived in the Tucson area.

Out of the 89 participants, 30 practiced Tai Chi, 28 took part in usual care, and 31 did SilverSneakers.  The SilverSneakers and Tai Chi groups exercised in a one-hour class three times a week for 12 weeks.  The group who just had the usual care received written material and a weekly phone call about participating in community-based physical activity.

During the 12-week trial, 34 reported falls in participants’ homes mostly from tripping or slipping:  five falls in the Tai Chi group, 14 falls in the SilverSneakers group, and 15 falls in the usual care group. 

"The main physical benefits of Tai Chi are better balance, improved strength, flexibility and aerobic endurance.  Psycho-social benefits include less depression, anxiety and stress, and better quality of life,” Taylor-Piliae said.
