U.S. Circumcision Rate Down 10 Percent over Past Three Decades
The circumcision rate of U.S. newborns dropped approximately 10 percent from 1979 to 2010, according to new date from the National Center for Health Statistics. In 2010 about 58.3 percent of boys born in U.S. hospitals were circumcised; the rate was 64.5 percent in 1979. While beginning as a religious ritual, the use of circumcision expanded due to potential health benefits such as reduced risk of urinary tract infections in infants and reduced risk of sexually transmitted diseases. Last August the American Academy of Pediatrics said that these benefits outweigh any risks. However, the procedure also has many opponents. While the report did not go much into the reasons for the decline, possible explanations include the fact that Medicaid has stopped paying for circumcisions in 18 U.S. states, some insurers are not covering procedures without strong medical justifications and shorter hospital stays for new mothers means some circumcisions are performed later as outpatient procedures.

Eating Fruit Helps Prevent Certain Aneurysms
An apple—or any other fruit—a day may lower a person’s risk of an abdominal aneurysm, according to a new study in the journal Circulation. The thirteen year study of 80,000 people ages 48 to 64 in Swede found that people who reported eating more than two servings of fruit daily had a 25 to 31 percent lower risk of abdominal aortic aneurysm than those who ate little or no fruit. High levels of antioxidants in fruits might protect against abdominal aortic aneurysm by preventing oxidative stress that can promote inflammation, according to the researchers, who found no similar association for vegetables, which are also rich in antioxidants, but may lack some of the components in fruits. However, vegetables remain important to a person’s diet, say the study authors. Combined with fruit they may help decrease the risk of cardiovascular diseases, type 2 diabetes, high blood pressure and several cancers. The American Heart Association advises the average adult to eat four to five servings each of fruits and vegetables daily, based on a 2,000 calorie diet. Read more on nutrition.
Study: CTE Victims First Present with Impaired Mood or Thinking
People suffering from chronic traumatic encephalopathy (CTE)—a neurodegenerative disease that can only be diagnosed after death—will likely first begin exhibiting either impaired behavior and mood or impaired memory and thinking abilities, according to a new study in the journal Neurology. CTE is characterized by impulsivity, depression and erratic behavior. "The study itself is relatively preliminary, [but] we found two relatively distinct presentations of the disease," said study co-author Daniel Daneshvar, a postdoctoral researcher at the university's Center for the Study of Traumatic Encephalopathy. "So little is known about the clinical presentation of CTE that anything we found is not necessarily surprising, simply because there's a dearth of information about CTE." Researchers emphasized that far more study is needed. CTE and other head trauma have become increasingly prominent issues over the last several years, with cases linked to both sports injuries and battlefield injuries. There is currently a lawsuit by almost 4,000 former NFL players claiming the league did not properly inform them of the dangers of concussions or adequately protect their health.
