Half of US adults have high blood pressure in new guidelines

Half of US adults have high blood pressure in new guidelines

Health
New guidelines lower the threshold for high blood pressure, adding 30 million Americans to those who have the condition, which now plagues nearly half of U.S. adults. High pressure, which for decades has been a top reading of at least 140 or a bottom one of 90, drops to 130 over 80 in advice announced Monday by a dozen medical groups. The change means an additional 14 percent of U.S. adults have the problem, but only 2 percent of these newly added people need medication right away; the rest should try healthier lifestyles, which get much stronger emphasis in the new advice. Poor diets, lack of exercise and other bad habits cause 90 percent of high blood pressure. "I have no doubt there will be controversy. I'm sure there will be people saying 'We have a hard enough time getting to 140,'" ...

FDA approves new gene therapy for blood cancer

Health
Oct. 18 (UPI) -- The U.S. Food and Drug Administration approved a new form of cell-based gene therapy for adults with certain types of large B-cell lymphoma, marking only the second time a gene therapy has been approved for the disease.The therapy is called Yescarta and will be used to treat patients with the deadly blood cancer who have not responded to other forms of treatment."Today marks another milestone in the development of a whole new scientific paradigm for the treatment of serious diseases," FDA Commissioner Scott Gottlieb said in a statement. "In just several decades, gene therapy has gone from being a promising concept to a practical solution to deadly and largely untreatable forms of cancer."Researchers call the gene therapy a "living drug" that attacks cancer cells through im...

Do e-cigarettes damage blood vessels?

Health
MONDAY, Sept. 11, 2017 -- Nicotine in e-cigarettes may cause stiffened arteries, which can lead to an increased risk for heart attack and stroke, a small Swedish study suggests.With the dramatic increase in e-cigarette use ("vaping") over the past few years, questions have arisen about their safety. And while many people think the devices are harmless, especially compared with regular cigarettes, little is known about long-term effects of these devices, according to lead researcher Magnus Lundback, from the Karolinska Institute in Stockholm."Increased arterial stiffness has previously been demonstrated following exposure to conventional cigarettes," said Lundback, who is a research leader and clinical registrar at the Danderyd University Hospital."We think that chronic exposure to e-cigare...
Prostate cancer blood test 'helps target treatment'

Prostate cancer blood test 'helps target treatment'

Health
Scientists have developed a blood test that could pick out which men with advanced prostate cancer would benefit from a new drug treatment.The test detects cancer DNA in the blood, helping doctors check whether precision drugs are working.Cancer Research UK said the test could "greatly improve survival".But larger studies involving more men needed to take place to confirm if doctors could rely on the test, the charity said.Blood samples from 49 men with advanced prostate cancer were collected by researchers, as part of the phase II clinical trial of a drug called olaparib.This type of precision drug is seen as the future of cancer medicine but because it is a targeted treatment, the drug does not work for everyone.Researchers from The Institute of Cancer Research and the Royal Marsden NHS ...
