Experts debate coverage of scans for Alzheimer's
by Karen Weintraub
The federal government will decide in early fall whether to pay for brain scans in people with suspected Alzheimer's disease…"As a neurologist who sees patients, I certainly would like to have the information provided by amyloid PET scans," said Ronald Petersen, director of the Mayo Clinic's Alzheimer's Disease Research Center, in Rochester, Minn.

George Bush’s Stent Surgery Revives Debate on Heart Care
by Michelle Cortez
Former President George W. Bush’s decision to allow doctors to use a stent to clear a blocked heart artery, performed absent symptoms, is reviving a national debate on the best way to treat early cardiac concerns… Stents are lifesaving when patients are in the midst of a heart attack, said Chet Rihal, an interventional cardiologist at the Mayo Clinic in Rochester, Minnesota, who has studied use of the devices. They allow immediate and sustained blood flow that help a patient recover, he said.

Context: Charanjit, "Chet" Rihal, M.D., chair, Division of Cardiovascular Diseases, is the William S. and Ann Atherton Professor of Cardiology Honoring Robert L. Frye, M.D. As a cardiologist, Dr. Rihal specializes in interventional cardiology with a focus on new device therapies, the treatment of acute myocardial infarction (heart attack), and structural heart disease. One area of expertise is replacing heart valves by catheterization through the arteries, avoiding chest surgery. Dr. Rihal applies clinical research techniques to answer questions about cardiovascular disease and improve patient safety. For example, each year, hundreds of thousands of X-rays are performed across the country to help detect and treat common cardiovascular conditions, but radiation can be harmful. In 2012, Dr. Rihal and his colleagues found a way to cut overall radiation exposure to these patients by nearly half using simple but effective methods.

Mayo Clinic researchers in Jacksonville find pancreatic cancer cause
by Michael Clinton
Researchers at Mayo Clinic in Florida have decoded the cause of inflammation-driven pancreatic cancer and potential solutions to reverse the process. The study was published in The Journal of Cell Biology Monday, and it shows how inflammation pushes acinar cells in the pancreas — those that produce digestive enzymes — to transform into duct-like cells. As these cells change, they can acquire mutations that can result in further progression to pancreatic cancer. Dr. Peter Storz, a biochemist and molecular biologist at Mayo Clinic’s Florida campus in Jacksonville, was a senior author on the study.
Mayo researchers: Inflammation 'initial step' to pancreatic cancer
by Lorna Benson
Mayo Clinic researchers in Florida say they've identified how chronic inflammation of the pancreas reprograms some cells and makes them more susceptible to cancerous mutations. Some white blood cells that respond to the inflammation drive the transformation of the damaged cells, rather than fix the problem, said Peter Storz, a Mayo biochemist and lead author of the study. "This process is believed to be an initial step leading to pancreatic cancer."
Context: Researchers at Mayo Clinic in Florida have revealed the process by which chronic inflammation of the pancreas, pancreatitis, morphs into pancreatic cancer. They say their findings point to ways to identify pancreatitis patients at risk of pancreatic cancer and to potential drug therapies that might reverse the process.

More Hospitals Offer Patients Rigorous Workouts After Heart Surgery by Laura Landro
Patients sometimes think that after heart surgery they are no longer at risk. "People are not cured after surgery, and there is still considerable prevention to do," says Randal Thomas, a preventive cardiologist at the Mayo Clinic in Rochester, Minn. Dr. Thomas is co-author of a study that found rehabilitation attendance was associated with a 46% reduction in the 10-year risk of death from all causes, regardless of a patient's age. The study, of coronary bypass patients at Mayo, was published in the July issue of the journal Circulation.
Circulation: The Wall Street Journal, a US-based newspaper published by Dow Jones & Company, is tops in newspaper circulation in America with an average circulation of 2 million copies on weekdays.
Context: Randal Thomas, M.D. is a Mayo Clinic cardiologist. This study, "Participation in Cardiac Rehabilitation and Survival After Coronary Artery Bypass Graft Surgery," appeared in the July issue of Circulation.

Mary Lahammer on living with multiple sclerosis
Keeping secrets isn’t easy for a born-and-bred journalist like TPT’s Mary Lahammer. That’s one reason she’s both relieved and eager to share news that she’s kept within a small circle for two years: She has multiple sclerosis, or MS.
Another reason has to do with the response she’s received from some of us in that circle who are old enough to remember when MS was a sure crippler and a death sentence.
It isn’t any longer, Lahammer says.
Don’t chalk up that assurance to an athlete’s determination or a young mother’s resolve, though at a vigorous age 39, she has both. Rather, I heard a journalist’s summation of two years of in-depth reporting among world-leading MS experts at Rochester’s Mayo Clinic, where she is a patient.

MS is a disease in which the immune system, which normally protects your body, instead attacks the covering (myelin sheath) surrounding the nerves in your brain and spinal cord. These nerves send information from your brain and spinal cord to other nerves in your body, and myelin helps make this transmission efficient.
Attacks of multiple sclerosis lead to inflammation and injury to the myelin sheath, resulting in slowed or blocked nerve signals, which can lead to difficulty controlling vision, muscle coordination, strength, sensation and other bodily functions.
Multiple sclerosis can affect people of any age, although symptoms most commonly occur in people 20 to 40 years old. Women are twice as likely to develop MS as are men.

More than 5 million Americans are thought to suffer from Alzheimer's disease, and now the federal government has set a new deadline to tackle the brain-wasting affliction. The National Alzheimer's Plan set a goal of finding new treatments, prevention and new training for doctors by 2025. Dr. Ronald Peterson is director of the Mayo Clinic Alzheimer's Disease Research Center and he's also chair of the advisory council that wrote the new national plan. Peterson acknowledged that the 13-year deadline may seem short for an affliction that, at least for now, has no proven treatment.

Your brain's capacity for information is a reliable predictor of Alzheimer's disease and can be cheaply and easily tested, according to scientists.
"We have developed a low-cost behavioral assessment that can clue someone in to Alzheimer's disease at its earliest stage," said Michael Wenger, associate professor of psychology at Penn State. "MRIs can cost hundreds of dollars an hour," Wenger said.
"We created a much cheaper alternative, based on a memory test, that correlates with hippocampal degradation." Wenger and his collaborators at the Mayo Clinic College of Medicine, Rochester, Minn., detail their findings in the current issue of the Journal of Mathematical Psychology…
Wenger worked with Selamawit Negash, neurology research fellow, Ronald C. Peterson, professor of neurology, and Lyndsay Peterson, research associate, all at the Mayo Clinic College of Medicine.
