(Press-News.org) Munich, Germany – August 27 2012: Renal denervation successfully treats patients with resistant hypertension in real world patient populations, according to a study presented at ESC Congress 2012. The findings were presented by Dr Darren Mylotte from France.
Transcatheter renal denervation represents a novel therapy for treating patients with treatment resistant hypertension, a condition which greatly increases the risk of myocardial infarction and stroke.
"The Symplicity Hypertension I and II studies have suggested that this procedure significantly lowers blood pressure in these patients with few remaining options in terms of treatment," said Dr Mylotte. "However, patients included in clinical trials are often highly selected, and therefore may not reflect the patient encountered by physicians on a day-to-day basis. As such, the results of these trials may not be applicable to less-selected patient populations."
In light of this potential problem, the investigators sought to evaluate the effect of transcatheter renal denervation in a group of patients with resistant hypertension in their own clinical practice at The Institut Cardiovasculaire de Paris Sud, Paris, France.
They intended to perform transcatheter renal denervation on 35 consecutive patients referred to the service with resistant hypertension. The study used the same definition as the Symplicity trials to define resistant hypertension (1).
Among these patients, 36.5% were female, 36.4% were diabetic, and 15.2% had kidney dysfunction. Baseline office blood pressure (BP) was 181.1±21.9 /100.8±16.8 mmHg, despite an average of 4.6±1.0 medications per patient. Successful bilateral sympathetic denervation was performed in 33 out of 35 patients (1 patient was not treated due to a stenosis of the renal artery; 1 patient had treatment on one side only, as multiple small renal arteries were found on the other side). No procedural complications occurred.
At 6-months follow-up, the average office BP reduction from baseline was 30.3±21.1/14.6±15.3 mmHg (P END

Renal denervation gives better outcomes than drugs in advanced heart failure
2012-08-27
Munich, Germany – August 27 2012: Renal denervation leads to better outcomes than standard drug treatment in patients with advanced heart failure, according to research presented at ESC Congress 2012. The results of the Olomouc I pilot study were presented by Dr Miloš Táborský from the University Hospital Olomouc.
Renal denervation does not involve any pharmacological treatment. It is a multiple application of radiofrequency energy using a thin catheter via the femoral artery and a long-term "denervation" of the sympathetic nerves around the renal arteries. "This is done ...
Precise and persistent cell sabotage
2012-08-27
Some of the body's own genetic material, known as small interfering RNA (siRNA), can be packaged then unleashed as a precise and persistent technology to guide cell behavior, researchers at Case Western Reserve University report in the current issue of the journal, Acta Biomaterialia.
The research group, led by Eben Alsberg, associate professor in the departments of Biomedical Engineering and Orthopedic Surgery, have been pursuing experiments that seek to catalyze stem cells to grow into, for example, bone and cartilage cells, instead of fat, smooth muscle and other cell ...
Athletic field paint steals spotlight from the grass it covers
2012-08-27
Aug. 27, 2012 – Professional athletic field managers maintain trimmed turfgrass with great precision, carefully painting crisp lines and colorful logos on their grass before each game. While these fields appear to be in perfect health, some field managers have noted deteriorating turfgrass beneath repeated paint applications.
New research now suggests why. In a study that appears in the September-October issue of Crop Science, three North Carolina State University researchers found that grasses coated with latex paints show a notable reduction in photosynthesis.

Zebra fish point the way towards new therapies for amyotrophic lateral sclerosis
2012-08-27
Leuven scientists (VIB/KU Leuven) are using zebrafish as a model in their search for genes that play a role in the mechanism of amyotrophic lateral sclerosis (ALS). As a result, they have identified a molecule that could be the target for a future ALS treatment. ALS is a progressive degenerative motor neuron disease for which there currently is no treatment. Their study has been published in the prestigious journal Nature Medicine.
Amyotrophic lateral sclerosis or ALS
ALS is a progressive paralyzing disease caused by the destruction of the neurons connecting to the muscles. ...
How methane becomes fish food
2012-08-27
Methane is an organic carbon compound containing the fundamental building block of nearly all living material: carbon. It provides an important source of energy and nutrients for bacteria. Methane is produced in oxygen-free environments and is found in abundance at the bottom of lakes.
The Brazilian post-doctoral researcher in biology and ecology, Angela Sanseverino, has presented a study that shows methane from lakebeds to be present in fish tissue. The study was carried out in cooperation with, inter alia, David Bastviken, Water and Environmental Studies (WES), Linköping ...
EARTH: Crowdsourcing for quake-monitoring
2012-08-27
Alexandria, VA – Technology is creating a new breed of scientist. I'm talking about citizen scientists – ordinary people and volunteers from all walks of life coming together to help monitor, and possibly mitigate, the next big earthquake through an innovative program called NetQuakes.
A play off the popular company Netflix – a movie company that allows users to rent movies through the mail – NetQuakes allows ordinary people to volunteer as a kind of host "family" for one of the program's many blue seismometers. This grassroots movement, an innovative effort between ...

Unexpected findings at multi-detector CT scans: Less reason to worry
2012-08-27
PROVIDENCE, R.I. – A new study from Rhode Island Hospital reports that nearly seven percent of urologic multi-detector computed tomography (MDCT) scans for hematuria result in incidental findings that may be clinically important for the patient. The study is published in the American Journal of Roentgenology.
It is known that urologic CT scans can sometimes show incidental findings. To date, however, there has been limited information about the prevalence and characteristics of those findings. Julie Song, M.D., a radiologist with Rhode Island Hospital's department of ...
