During National Diabetes Awareness Month, New Report Ties Disease to Shortened Life Expectancy

Diabetes • • Public HealthNov 30 10

Despite medical advances enabling those with diabetes to live longer today than in the past, a 50-year-old with the disease still can expect to live 8.5 years fewer years, on average, than a 50-year-old without the disease.

This critical finding comes from a new report commissioned by The National Academy on an Aging Society and supported by sanofi-aventis U.S. The analysis - based on data from the Health and Retirement Study (HRS) - found that older adults with diabetes have a lower life expectancy at every age than those without the disease. At age 60, for example, the difference in life expectancy is 5.4 years. By age 90, the difference is one year.

“Given the rise in diabetes among boomers and seniors, these findings are alarming,” said Greg O’Neill, PhD, director of the Academy. “They paint a stark picture of the impact of diabetes and its complications on healthy aging.”

The Not-so-Sweet Truth About Sugar- A Risk Choice?

Dieting • • Urine ProblemsNov 30 10

More and more people have become aware of the dangers of excessive fructose in diet. A new review on fructose in an upcoming issue of the Journal of the American Society of Nephrology (JASN) indicates just how dangerous this simple sugar may be.

Richard J. Johnson, MD and Takahiko Nakagawa, MD (Division of Renal Diseases and Hypertension, University of Colorado) provide a concise overview of recent clinical and experimental studies to understand how excessive amounts of fructose, present in added sugars, may play a role in high blood pressure, diabetes, obesity, and chronic kidney disease (CKD).

Dietary fructose is present primarily in added dietary sugars, honey, and fruit. Americans most frequently ingest fructose from sucrose, a disaccharide containing 50% fructose and 50% glucose bonded together, and high fructose corn syrup (HFCS), a mixture of free fructose and free glucose, usually in a 55/45 proportion.

A ‘USB’ for medical diagnosis?

Public HealthNov 29 10

Biomedical engineers at UC Davis have developed a plug-in interface for the microfluidic chips that will form the basis of the next generation of compact medical devices. They hope that the “fit to flow” interface will become as ubiquitous as the USB interface for computer peripherals.

UC Davis filed a provisional patent on the invention Nov. 1. A paper describing the devices was published online Nov. 25 by the journal Lab on a Chip.

“We think there is a huge need for an interface to bridge microfluidics to electronic devices,” said Tingrui Pan, assistant professor of biomedical engineering at UC Davis. Pan and graduate student Arnold Chen - invented the chip and co-authored the paper.

Gene therapy prevents memory problems in mice with Alzheimer’s disease

Brain • • GeneticsNov 29 10

Scientists at the Gladstone Institute of Neurological Disease (GIND) in San Francisco have discovered a new strategy to prevent memory deficits in a mouse model of Alzheimer’s disease (AD). Humans with AD and mice genetically engineered to simulate the disease have abnormally low levels of an enzyme called EphB2 in memory centers of the brain. Improving EphB2 levels in such mice by gene therapy completely fixed their memory problems. The findings will be published in the November 28 issue of the journal Nature.

In both humans and mice, learning and memory requires effective communication between brain cells called neurons. This communication involves the release of chemicals from neurons that stimulate cell surface receptors on other neurons. This important process, called neurotransmission, is impaired by amyloid proteins, which build up to abnormally high levels in brains of AD patients and are widely thought to cause the disease. But how exactly these poisonous proteins disrupt neurotransmission is unknown.

“EphB2 is a really cool molecule that acts as both a receptor and an enzyme,” said Moustapha Cisse, PhD, lead author of the study. “We thought it might be involved in memory problems of AD because it is a master regulator of neurotransmission and its brain levels are decreased in the disease.”

Harm in hospitals still common for patients

Public HealthNov 25 10

Despite a decade of efforts to improve patient safety in hospitals—initially inspired by a seminal report on the problem from the U.S. Institute of Medicine in 2000—harmful errors and accidents are still common, new research suggests.

The study, published in the New England Journal of Medicine, showed that between 2002 and 2007, the number of patients experiencing infections acquired in the hospital, medication errors, complications from diagnostic techniques or treatments, and other such “harms” did not change.

Researchers looked at 2,300 patient admission records from 10 randomly selected hospitals in North Carolina. They found 588 incidents of patient harm resulting from medical procedures, medications, or other causes. Two-thirds of these complications were considered preventable by reviewers at the hospitals themselves.

An answer to a longstanding question: How HIV infection kills T cells

AIDS/HIVNov 24 10

Researchers appear to have an explanation for a longstanding question in HIV biology: how it is that the virus kills so many CD4 T cells, despite the fact that most of them appear to be “bystander” cells that are themselves not productively infected. That loss of CD4 T cells marks the progression from HIV infection to full-blown AIDS, explain the researchers who report their findings in studies of human tonsils and spleens in the November 24th issue of Cell, a Cell Press publication.

“In [infected] primary human tonsils and spleens, there is a profound depletion of CD4 T cells,” said Warner Greene of The Gladstone institute for Virology and Immunology in San Francisco. “In tonsils, only one to five percent of those cells are directly infected, yet 99 percent of them die.”

Lymphoid tissues, including tonsils and spleen, contain the vast majority of the body’s CD4 T cells and represent the major site where HIV reproduces itself. And it now appears that those dying T cells aren’t bystanders exactly.

Researchers say uncover HIV, insulin resistance link

AIDS/HIV • • DiabetesNov 24 10

Researchers at the Washington of Medicine say they have uncovered why so many people with the HIV virus develop a dangerous insulin resistance that leads to diabetes and heart disease.

The culprit lies in the powerful drugs that prevent the development of AIDS and have extended the lives of many HIV patients, the researchers say. They hope the discovery will allow development of safer antiviral drugs.

The research, published this month in the Journal of Biological Chemistry, shows HIV protease inhibitor drugs directly interfere with the way blood sugar levels are controlled in the body.

No family link seen between Parkinson’s, melanoma

Brain • • Cancer • • NeurologyNov 24 10

Research has suggested that families affected by melanoma skin cancer may also have a higher-than-average rate of Parkinson’s disease—but a large new study found no evidence of such a link.

This doesn’t mean no genetic link exists, the authors of the new study say. But it does suggest that such a link might not have very important effects.

Melanoma is the least common, but most serious, form of skin cancer. The disease sometimes runs in families, and people with two or more close relatives who have had melanoma are considered to be at higher-than-average risk.

Cholera fighting efforts restart in Haiti’s north

Infections • • Public HealthNov 22 10

Aid supplies to combat Haiti’s deadly cholera epidemic are flowing again into the country’s northern regions after protests by Haitians blaming U.N. troops for the outbreak, humanitarian groups said on Sunday.

Vehicles carrying equipment from some aid groups have begun to reach the northern city of Cap-Haitien, where aid efforts were disrupted last week by several days of protests that saw Haitians throw up road barricades and hurl stones at U.N. peacekeepers, said Imogen Wall of the U.N. humanitarian agency, OCHA.

“The security situation there has now stabilized,” Wall said. “We’re going to have to scramble to get back to where we were.”

Moms’ mealtime tactics tied to kids’ eating habits

DietingNov 22 10

School-age children whose mothers tightly control their diets may be prone to overeating, while those with moms who pressure them to eat tend to be fussy about food, a new study finds.

The findings, published in the Journal of the American Dietetic Association, do not necessarily mean that parents’ mealtime strategies cause their children to overeat or become picky eaters.

In fact, the researchers say, it’s likely that parents who pressure or restrict are often reacting to their children’s eating habits.

1. Potassium Citrate May Help Prevent and Treat Osteoporosis Supplement Neutralizes Bone Damage Inflicted by the Western Diet

The Western diet creates an acidic environment in the body that removes calcium from bones and may contribute to the development of osteoporosis. Healthy adults who consume the standard US diet sustain a chronic, low-grade state of acidosis that worsens with age as kidney function declines, limiting urinary acid excretion. Reto Krapf, MD (University of Basel, in Bruderholz/Basel, Switzerland) and colleagues designed a study to see if daily alkali as potassium citrate supplement tablets might neutralize these effects. They enrolled 201 healthy elderly individuals of both genders with normal bone mass in a randomized double-blind, placebo-controlled clinical trial. Participants received either 60 mmol alkali as potassium citrate (a base) or a placebo every day for 2 years. Bone density and high resolution computed tomography scans after 2 years revealed that neutralizing diet-induced acid production with potassium citrate significantly and safely increased subjects’ bone density vs. placebo. “In addition, we discovered that bone architecture improved significantly, suggesting that not only bone mass, but also its quality was improved,” said Dr. Krapf. These results suggest and predict that potassium citrate may be effective for preventing and even treating osteoporosis.

Study co-authors include Sigrid Jehle, MD (University of Basel, in Bruderholz/Basel, Switzerland) and Henry N. Hulter, MD (FibroGen, Inc., San Francisco).

UK starts world’s first stroke stem cell trial

Public Health • • StrokeNov 17 10

Doctors in Scotland working with British biotech company ReNeuron have injected stem cells into the brain of a man in a pioneering clinical trial to test the safety of a therapy for patients disabled by stroke.

The trial is the first in the world to use neural stem cell therapy in stroke patients, its organisers said on Tuesday, and external experts said it was grounds for “cautious optimism.”

Keith Muir of the University of Glasgow’s Institute of Neuroscience and Psychology, the principal investigator, said the surgery on the first patient, a man in his 60s, had gone well and he had been discharged from hospital.

Sinai Hospital’s Krieger Eye Institute Opens New Retina Center

Eye / Vision ProblemsNov 17 10

The Krieger Eye Institute at Sinai Hospital opened a new center for the treatment of retinal diseases in November. The retina is the layer of tissue at the back of the eye that converts images to electrical impulses. These electrical signals are then perceived by the brain as sight.

The Retina Center treats all retinal diseases including macular degeneration, hypertensive retinopathy, pediatric retinopathy, diabetic retinopathy and sickle cell retinopathy.

“The approach to treating retinal disease has changed drastically in the last few years,” says Donald Abrams, M.D., chief of the Department of Ophthalmology at Sinai Hospital. “This new center allows us to more effectively treat patients suffering from these diseases.”

Lower back and foot pain associated with more severe knee osteoarthritis symptoms

Arthritis • • ImmunologyNov 17 10

A new study found that patients with osteoarthritis (OA) of the knee who also have pain in other joints were more likely to experience greater knee pain. Specifically, pain in the lower back as well as foot pain and elbow pain on the same side as the affected knee were associated with more severe knee pain. Full details appear in the December issue of Arthritis Care & Research, a journal published by Wiley-Blackwell on behalf of the American College of Rheumatology.

Knee OA is the leading cause of disability in the U.S., with nearly 4.3 million adults over age 60 having the symptomatic form of the disease according to the Centers for Disease Control and Prevention (CDC). A study by Helmick et al. published in Arthritis & Rheumatism reported 59 million people have low back pain, which is the most common cause of lost work time among individuals less than 45 years of age and the third most common cause among those 45 to 65 years of age.

The current study team led by Pradeep Suri, M.D., from Harvard Medical School, New England Baptist Hospital, and Spaulding Rehabilitation Hospital in Boston, Massachusetts used data provided by individuals from the Osteoarthritis Initiative - a multicenter population-based observational cohort study of knee OA.
