Fewer Physicians Offer Charity Care: Survey
According to a survey released by the Center for Studying Health System Change, the number of doctors who provide free care to the poor and uninsured has dropped over the past decade, declining across all major specialties. Dr. Peter Cunningham, senior researcher for the center, said he believes the drop reflects several trends: stagnant reimbursement rates from the government, and lower fees negotiated by insurance companies on behalf of their customers. He also cites an increase in the number of physicians joining large group practices that have less control over the type of patients they see.
Exercise may Be Alternate ADHD Treatment
Doctors are studying a variety of non-medical treatments for attention deficit hyperactivity disorder. There hasn't been any definitive studies concerning exercise and ADHD, but David Goodman, an assistant professor at John Hopkins University School of Medicine, says that it makes sense that working out would help people cope with the condition. Studies show that exercise increases levels of 2 key brain chemicals, dopamine and norepinephrine, that help people to focus.
Mice May Provide Embryonic Stem Cells
New research published by the journal Nature says German scientists have identified cells from the testes of mice that can behave like embryonic stem cells. If the same holds true for humans testes, it could provide a controversy-free source of versatile cells for use in treating disease.
New IVF Method Uses Fewer Eggs
A new in vitro fertilization method called minimal stimulation uses low-dose oral drugs in place of a daily regimen of hormone shots. Although the success rate is lower than standard IVF procedures, minimal stimulation uses fewer eggs, making it a simpler option for most women than traditional IVF.
