Diabetes, obesity called largest health threat US faces
Miami Herald    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Obesity has become a national epidemic. In 2010 a third of U.S. adults — the equivalent of 33.8 percent of the nation's population — and 17 percent of children and adolescents were considered obese. The 25.8 million diabetes patients are not exempt. According to the American Diabetes Association, more than 80 percent of the nearly two million people diagnosed with diabetes every year are considered obese. In fact, the Center for Disease Control and Prevention has categorized "the combined epidemic of obesity and diabetes" as the largest health threat the United States faces in the 21st century. More

Bench to bedside — Using research approaches to impact healthcare
JSNMA    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The authors said the purpose of this study was to compare the abilities of two popular Anterior Cruciate Ligament reconstruction techniques to restore native knee motion during weight-bearing flexion in 21 patients with unilateral reconstruction; 12 with transtibial and 10 with independent. We hypothesized that grafts placed using an independent approach previously shown to place the graft anatomically on the femur, will more closely restore the native knee motion throughout the weight-bearing activity.

New student loan plan: Who qualifies and how to enroll
Fox Business    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Some recent grads might have let out a sigh of relief when President Barack Obama announced his proposal to accelerate existing plans to relieve some of their student loan burden, including a new version of the IBR plan. But experts caution that not all grads will be eligible for the new programs. The Income-Based Repayment (IBR) plan was designed to cap a borrower's monthly student loan payments at a percentage of the discretionary borrower's income, based on the borrower’s income and family size rather than the total amount of their loan. The monthly payment is adjusted each year as the borrower’s income and family size changes. More

Australian scientists discover new way to treat Parkinson's disease
Science Alert    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Australian scientists have developed a new technique using stem cells, in the hope to replace damaged cells in Parkinson's disease. The technique could be developed for application in other degenerative conditions. Dr. Clare Parish and Dr. Lachlan Thompson lead the research from the Florey Neuroscience Institutes and the University of Melbourne in Australia. They are members of the newly established Stem Cells Australia collaboration launched at the University of Melbourne. More

Group: PSA recommendations not for blacks
United Press International    Share    Share on FacebookTwitterShare on LinkedinE-mail article
U.S. recommendations to limit prostate specific antigen (PSA)as a screening test are based on studies involving few African-Americans, researchers say. The National Medical Association, an association representing more than 50,000 African-American physicians, said the large clinical studies performed on the PSA in Europe, Canada and the United States involved few African-American men and as a result, the findings might not be generalizable to the black community.

Moles, eye color and the genetics of skin cancer
Australian Life Scientist    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A new study has identified that a gene variation associated with a greater number of moles and non-blue eye color is linked to an increased risk of melanoma. A gene that is responsible for regulating pigmentation of the skin, and is associated with a greater number of moles and non-blue eye color, has been linked to a greater risk of melanoma. More

Bacterial genes tell the tale of an outbreak's evolution
Medical Xpress    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers at Harvard Medical School and Children's Hospital Boston have retraced the evolution of an unusual bacterial infection as it spread among cystic fibrosis patients by sequencing scores of samples collected during the outbreak, since contained. A significant achievement in genetic pathology, the work also suggests a new way to recognize adaptive mutations — to see evolution as it happens — and sheds new light on how our bodies resist infection.

'Moonlighting' enzyme unravels arginine paradox
Baylor College of Medicine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Nearly 20 years ago, the journal Science tagged nitric oxide as the "molecule of the year." Since that time, researchers have tried to study and target this simple molecule that is involved in virtually every process of the body. However, focusing on the molecule and the enzyme directly involved in its production has proven difficult and futile. Now, researchers at Baylor College of Medicine have not only found a way to change the production of nitric oxide in the cell, along the way, they may have solved the mystery of the "arginine" paradox. They describe their work in an article in the current issue of the journal Nature Medicine. More

Black children less likely to get kidney transplant before dialysis
HealthDay via U.S. News & World Report    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Minority children are less likely than white children to get a kidney transplant before their kidney disease gets so bad they need dialysis, U.S. researchers have found. They also discovered that black children with kidney failure and no health insurance are more likely than whites to die while waiting for a kidney transplant. The Emory University researchers analyzed 2000-08 data from the U.S. Renal Data System, and found that white children had a 56 percent higher average annual rate of preemptive transplants than blacks and a 50 percent higher rate than Hispanics. A preemptive transplant is one performed before a patient begins dialysis. More

Computer 'pathologist' could assess breast cancer survival
USA Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A new computer model analyzes microscopic breast cancer images and predicts patient survival better than the pathologists who do the job now, new research suggests. The computer program "provides information above and beyond what the physician provides, using the same data," said Daphne Koller, a professor of computer science at Stanford University and senior author of the study. The computer model is called Computational Pathologist, or C-Path. More

Blog: Medical schools neglect gay and gender issues
The New York Times    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A physician says, "While we had been trained well in treating cancer with the best chemotherapy regimen, curing flesh-eating infections with the most powerful antibiotics or transplanting organs with the greatest of ease, when it came to caring for patients who were transgender, we were lost. For many of us, the same could be said for lesbian, gay and bisexual patients as well. The only thing most of us knew how to do was ask about a single issue: 'Whom are you having sex with? Men, women or both?' " More

White, mixed-race youths rank high in alcohol, substance abuse
Los Angeles Times    Share    Share on
FacebookTwitterShare on LinkedinE-mail article
The first-ever survey of adolescent alcohol and drug abuse to recognize youths of mixed race or ethnicity has found that such kids hover closest to white adolescents in the rate at which they suffer substance abuse disorders. That is not reassuring, because white adolescents are among the most likely ethnic and racial groups to have substance-use disorders. More
