A New Method For Treating Stubborn Hypertension.
A romance access to blast away kidney nerves has a striking effect on lowering blood pressure in mettle patients whose blood pressure wasn't budging despite trying multiple drugs, Australian researchers report. Although this sanctum only followed patients for a short time - six months - the authors put faith the approach, which involves delivering radiofrequency energy to the so-called "sympathetic " nerves of the kidney, could have an cause on heart disease and even help lower these patients' hazard of death. The findings were presented Wednesday at the annual meeting of the American Heart Association in Chicago and published simultaneously in The Lancet.
The swat was funded by Ardian, the company that makes the catheter emblem used in the procedure. "This is an extremely important study, and it has the potential for honestly revolutionizing the way we deal with treatment-resistant hypertension," said Dr Suzanne Oparil, director of the Vascular Biology and Hypertension Program at the University of Alabama at Birmingham. Oparil spoke at a message bull session Wednesday to announce the findings, though she was not involved in the study.
Treatment-resistant blood pressure, defined as blood press that cannot be controlled on three drugs at full doses, one of which should be a diuretic, afflicts about 15 percent of the hypertensive population. "Many patients are wild on four or five drugs and have truly refractory hypertension. If it cannot be controlled medically, it carries a extreme cardiovascular risk".
This radioablation procedure had already successfully prevented hypertension in unrefined models. According to study author Murray Esler, the symbol specifically targets the kidneys' sympathetic nerves. Previous studies have indicated that these nerves are often activated in vulnerable hypertension a cardiologist and scientist at the Baker IDI Heart and Diabetes Institute in Melbourne, Australia.

Treatment Options For Knee
Treatment Options For Knee.
Improvements in knee despair following a common orthopedic form appear to be largely due to the placebo effect, a new Finnish study suggests. The research, which was published Dec 26, 2013 in the New England Journal of Medicine, has heavy implications for the 700000 patients who have arthroscopic surgery each year in the United States to fixing a torn meniscus. A meniscus is a C-shaped filling of cartilage that cushions the knee joint.
For a meniscal repair, orthopedic surgeons use a camera and trifling instruments inserted through small incisions around the knee to shear damaged tissue away. The idea is that clearing sharp and unstable debris out of the communal should relieve pain. But mounting evidence suggests that, for many patients, the procedure just doesn't pan out as intended. "There have been several trials now, including this one, where surgeons have examined whether meniscal run surgery accomplishes anything, basically, and the answer through all those studies is no, it doesn't," said Dr David Felson, a professor of medication and public health at Boston University.
He was not convoluted in the new research. For the new study, doctors recruited patients between the ages of 35 and 65 who'd had a meniscal dash and knee pain for at least three months to have an arthroscopic wont to examine the knee joint. If a patient didn't also have arthritis, and the surgeon viewing the knee ascertained they were eligible for the study, he opened an envelope in the operating room with further instructions.
At that point, 70 patients had some of their damaged meniscus removed, while 76 other patients had nothing further done. But surgeons did all they could to place the sham procedure seem like the real thing. They asked for the same instruments, they moved and pressed on the knee as they otherwise would, and they occupied mechanical instruments with the blades removed to simulate the sights and sounds of a meniscal repair. They even timed the procedures to total sure one wasn't shorter than the other.
