PROVIDENCE, RI/WASHINGTON, March 29 (Reuters) – Patients
treated by renal artery denervation were no more likely to see
their blood pressure decline than those who received a fake
therapy in a major clinical trial, calling into question a
therapy used in more than 80 countries to treat hypertension
that doesn’t respond to drugs.
The study was considered a key test of the intervention in
which nerve connections between the heart and kidney were
disrupted in an effort to lower blood pressure as prior trials
did not include a blinded control group for efficacy comparison.
WASHINGTON (Reuters) – Switching over to daylight saving time, and losing one hour of sleep, raised the risk of having a heart attack the following Monday by 25 percent, compared to other Mondays during the year, according to a new U.S. study released on Saturday.

WASHINGTON, March 29 (Reuters) – Medtronic Inc’s
minimally invasive CoreValve system for replacing diseased
aortic heart valves led to a significantly higher survival rate
after one year than traditional open heart surgery in patients
deemed at high risk of death during surgery, according to data
from a study presented on Saturday.
One year after receiving the CoreValve in the 795-patient
Phase III trial, the rate of death was 14.2 percent compared
with a 19.1 percent death rate in the surgery group, researchers
said. The result, presented at the American College of
Cardiology scientific meeting in Washington, was deemed to be

(Reuters) – A spate of regulatory warnings for India’s generic drug manufacturers will add a new emphasis on the quality of such medicines in an industry long dominated by the ability to deliver treatments as cheaply as possible, analysts say.
In the short term, that is expected to benefit larger global competitors, such as Teva Pharmaceutical Industries Ltd, Actavis Plc and Mylan Inc, which will be called upon to supply drugs no longer available from some of their rivals in India, they said.

(Reuters) – An experimental Johnson & Johnson drug for moderate to severe psoriasis proved significantly better at clearing the scaly, uncomfortable skin patches associated with the disease than a placebo, according to data from a midstage study presented on Saturday.
The J&J biologic medicine, guselkumab, achieved the main goal of the Phase II study at all five dosing regimens tested by clearing or reducing the psoriasis to a minimal measure after 16 weeks of treatment in a far greater percentage of patients than in the group that received a placebo. It also appeared to be as good as or more effective than AbbVie’s big selling Humira at four of the tested doses.
