(Press-News.org) Philadelphia, PA (October 28, 2014) — Home blood pressure monitors may be inaccurate in up to 15% of patients, according to a study that will be presented at ASN Kidney Week 2014 November 11¬–16 at the Pennsylvania Convention Center in Philadelphia, PA.
Major guidelines recommend home blood pressure monitoring to guide diagnosis and treatment of patients with hypertension; however, little is known about the real-world accuracy of home blood pressure monitors that patients use. Researchers led by Swapnil Hiremath, MD, MPH (Ottawa Hospital and University of Ottawa, in Canada) compared measurements from home blood pressure monitors with validated mercury sphygmomanometers, which are used in doctors' offices, in 210 patients.
The investigators found that 63/210 of the home monitor systolic blood pressure readings (30%) were > 5 mm Hg different and 16 (8%) were > 10 mm Hg different from the mercury systolic blood pressure measurement. For diastolic blood pressure, these proportions were 32% (67/210) and 9% (18/210) respectively.
"Home blood pressure monitors may be inaccurate in 5% to 15% of patients, depending on the threshold for accuracy used," said Dr. Hiremath. "We recommend all patients with home monitors get them validated with their health care providers at least once."

Researchers from the National University of Singapore (NUS) have discovered a new reproductive mode in frogs and toads - breeding and laying direct developing eggs in live bamboo with narrow openings - which was observed in the white spotted bush frog (Raorchestes chalazodes). This critically endangered frog is currently only one of two species known to adopt this novel reproductive strategy. The findings were published in The Linnean Society of London's Biological Journal of the Linnean Society, in October 2014.

Individual differences in moving activity in a novel environment are linked to individual differences in vulnerability to angling, according to an experimental study completed at the University of Eastern Finland and the Finnish Game and Fisheries Research Institute. The study used novel, long-term observations of individual behaviour in groups and authentic angling trials to analyse if behaviours predict the vulnerability to fishing in brown trout reared in traditional and enriched hatchery rearing environments. Based on the results, it can be predicted that fishing modifies ...
Experts agree that it's a great way of staying fit and healthy at any age, but when faced with higher prices people are likely to swim less often, while other forms of physical activity such as working out or walking are barely affected.
According to a study by Brunel University London's Health Economics Research Group (HERG), swimming is the individual activity that most people would drop if they faced higher prices.
The study included interviews with 1,683 people, 83% of whom took part in physical activity in some form. It found that people facing 10% higher entry ...
Tea and citrus fruits and juices are associated with a lower risk of developing ovarian cancer, according to new research from the University of East Anglia (UEA).
Research published today reveals that women who consume foods containing flavonols and flavanones (both subclasses of dietary flavonoids) significantly decrease their risk of developing epithelial ovarian cancer, the fifth-leading cause of cancer death among women.
The research team studied the dietary habits of 171,940 women aged between 25 and 55 for more than three decades.
The team found that those ...

New research by the University of California, Davis, shows that chimpanzees plan ahead, and sometimes take dangerous risks, to get to the best breakfast buffet early.
The study co-authored by Leo Polansky, an associate researcher in the UC Davis anthropology department, reveals that chimpanzees will find a place to sleep en route to breakfast sites and risk travel in the dark when predators are active to obtain more desired, less abundant fruits such as figs. The study is being published by the Proceedings of the National Academy of Sciences of the United States of America.

Boston, MA — People who swap 5% of the calories they consume from saturated fat sources such as red meat and butter with foods containing linoleic acid—the main polyunsaturated fat found in vegetable oil, nuts, and seeds—lowered their risk of coronary heart disease (CHD) events by 9% and their risk of death from CHD by 13%, according to a new study led by Harvard School of Public Health (HSPH) researchers. Substitution of 5% of calories from carbohydrate with linoleic acid was associated with similar reductions in risk of heart disease.

Is generosity less stressful than being stingy?
QUT research, published in scientific journal Public Library of Science (PLOS) ONE, examined the physiological reactions of participants in a financial bargaining game and found that not only those receiving relatively low offers experienced stress but also those that make low offers, when compared to people who made more generous offers.
Participants were asked to play the Ultimatum Bargaining Game, in which players decide how to divide a sum of money given to them.
Player one (the proposer) proposes how to divide ...
Spices and herbs can play a significant role in improving America's health by helping to reduce sodium, calorie and fat intake while making healthy eating more appealing, conclude the authors of a scientific supplement published this month in the peer-reviewed journal Nutrition Today.

CAPE TOWN, October 28, 2014 – The risk of acquiring herpes simplex virus type 2 (HSV-2) was reduced by half among women in the VOICE trial who used a vaginal gel containing the antiretroviral (ARV) drug tenofovir regularly, according to researchers from the U.S. National Institutes of Health-funded Microbicide Trials Network (MTN) who conducted the study. The findings provide additional evidence that tenofovir gel, a product developed to protect against HIV, could potentially help in preventing one of the most prevalent sexually transmitted infections affecting sexually ...
