Scientists Breach Brain Barrier to Treat Sick Patient

For the first time, doctors have breached the human brain's protective layer to deliver cancer-fighting drugs. The Canadian team used tiny gas-filled bubbles, injected into the bloodstream of a patient, to punch temporary holes in the blood-brain barrier. A beam of focused ultrasound waves applied to the skull made the bubbles vibrate and push their way through, along with chemotherapy drugs. Six to 10 more patients will undergo the same procedure as part of a trial. Via BBC.

Getting Your Blood Pressure Even Lower: Here are the Risks and Rewards 

Two months ago, U.S. officials crowed that a federally funded study gauging the impact of stricter blood pressure control had produced such dramatic results, they were bringing the clinical trial to an early close. Recently, those dramatic results got medicine's version of a ticker-tape parade: a research article and not one but three editorials in the New England Journal of Medicine detailed and dissected just how steeply heart disease, strokes, and deaths from any cause declined in patients who aimed to get their systolic blood pressure reading to 120 mm of mercury. Via LA Times.

Use of Long-Acting Birth Control Methods Surges Among U.S. Women

The share of American women on birth control who use long-acting reversible methods like intrauterine devices and implants has nearly doubled in recent years, the federal government reported. The share of women on birth control who use the devices rose to 11.6 percent in the period from 2011 to 2013, up from 6 percent in 2006 to 2010, according to the National Center for Health Statistics. The share is still smaller than for the pill (26 percent) or condoms (15 percent), but it is the fastest-growing method. In 2002, just 2.4 percent of women on birth control in the United States used the long-acting methods. Via NY Times.

Advising People About Heart Risk Genes Helped Cut Cholesterol

In the study presented at the American Heart Association meeting in Orlando, Florida, researchers at Mayo Clinic in Rochester, Minnesota, tested the theory that incorporating genetic risk information into an assessment of a person's heart disease risk could lead to lower levels of LDL, the portion of cholesterol that leads to heart attacks and stroke. "What we found is six months after the risk disclosure, the LDL cholesterol in those who got the genetic risk information was about 10 points lower, which was statistically significant," said Dr. Iftikhar Kullo, a Mayo Clinic cardiologist who led the study. Via Reuters.

Belly Fat May Be More Dangerous for the Heart Than Obesity

No one would mistake a beer gut for a sign of health. But a new study finds that carrying extra pounds around the middle can be dangerous even for people with an overall healthy weight. In a 14-year study of more than 15,000 people, normal-weight men with big bellies were twice as likely to die compared to men who were obese. Women with normal weights and big bellies were 32 percent more likely to die during the study than obese women, according to the study, led by Francisco Lopez-Jimenez, a Mayo Clinic cardiologist. Via USA Today.

Mayo Developing Blood Test For Concussion Detection 

Days after the Vikings’ quarterback took a major hit to the head, new research suggests there may be a new way to detect concussions by way of a simple blood test. Researchers at Orlando Health found that a blood test correctly identified traumatic brain injuries in 94 percent of the cases studied. According to Dr. Jonathan Finnoff, who specializes in sports medicine at the Mayo Clinic, “You essentially stun the nerves in your brain, and so they’re temporarily not working,” Finnoff said during a concussion. Via WCCO.
