Two daily doses of a probiotic lowered key cholesterol-bearing molecules in the blood as well as "bad" and total cholesterol, in a study presented at the American Heart Association's Scientific Sessions 2012.
Probiotics are live microorganisms (naturally occurring bacteria in the gut) thought to have beneficial effects; common sources are yogurt or dietary supplements.In previous studies, a formulation of the bacteria, known as Lactobacillus reuteri NCIMB 30242, has lowered blood levels of LDL or "bad" cholesterol.
Hispanics and Latinos living in the U.S. are highly likely to have several major cardiovascular disease risk factors, such as high cholesterol, high blood pressure, obesity, diabetes, and smoking, according to a new, large-scale study. Risks vary among the diverse Hispanic/Latino groups, but individuals who were born in the U.S. are more likely to have multiple risk factors.
The findings are reported in the Nov. 7 issue of JAMA.
The economic impact of a heart attack and other forms of acute coronary syndrome goes beyond the hospital to the home and workplace, according to research presented at the American Heart Association's Scientific Sessions 2012.
Men and women with acute coronary syndrome face additional economic burdens in lost time and income from work and possible inability to return to work, researchers said.
Acute coronary syndrome (ACS) is an umbrella term for situations in which blood supplied to the heart muscle is suddenly blocked. It includes heart attack and angina or chest pain.
Boulder, Colorado, USA - Throughout history, people have sought to understand how the world came to be and how it has changed over time. This curiosity has produced a rich legacy of science and philosophy and also influenced religion and theology. In the November 2012 issue of GSA Today, David Montgomery of the University of Washington examines the history of geology and of biblical views regarding Earth's origins.
Family members didn't give CPR for cardiac arrests as often as passers-by or friends in a Japanese study presented at the American Heart Association's Scientific Sessions 2012.
Cardiac arrest is the sudden loss of heart function, typically resulting from an abnormal heart rhythm that causes the heart to quiver erratically and stop pumping blood. According to the American Heart Association, effective bystander CPR provided immediately after sudden cardiac arrest can double or triple a victim's chance of survival.
In one of the largest and longest trials involving patients with kidney failure, a study led by an international team of researchers found that cinacalcet — a drug commonly prescribed to patients with kidney failure and a disturbance of bone and mineral metabolism known as secondary hyperparathyroidism — does not significantly reduce the risk of death or major cardiovascular events.
The results of the trial known as EVOLVE, which enrolled nearly 4,000 kidney patients from several continents and stretched over five years, were mixed, researchers said.
Three late-breaking studies presented during the American Society of Nephrology's Annual Kidney Week provide new information on drugs being tested in patients with diabetes or kidney disease.
SAN DIEGO -- A drug therapy shows promise for treating an inherited form of kidney disease called autosomal dominant polycystic kidney disease (ADPKD), Mayo Clinic researchers say. The medication, tolvaptan, slowed the pace of kidney cyst growth over the three years of the study. The phase three clinical trial results were being presented today at the American Society of Nephrology annual meeting and published online in the New England Journal of Medicine.
Boulder, CO, USA – In response to the devastation caused last week by Hurricane Sandy, organizers of the Geological Society of America Annual Meeting technical sessions on rapid sea-level rise and its impacts have created a break-out discussion panel consisting of geoscience experts. The idea is to relate early findings and discuss how the changes caused by Hurricane Sandy to the U.S. East Coast tie into the scientific papers already scheduled for presentation.
HERSHEY, Pa. -- Extending Medicaid coverage to currently uninsured adults is likely to increase the cost of the program, according to health policy researchers, because those patients are prone to have more expensive health problems than nondisabled adults currently enrolled in Medicaid.
The Affordable Care Act gives individual states the option to expand their Medicaid programs to cover many who are uninsured. A study by Penn State and Wake Forest University researchers is among the first to quantify the potential financial impact of this option.
Income inequality and government redistribution of wealth has become a major topic of discussion during the ongoing recession, chronically high unemployment and record food stamp usage, and yet consensus on what (if anything) should be done about it seems elusive. New survey results published in Psychological Science suggest that a simple manipulation of language might be able to influence support for policies aimed at addressing income inequality.
During presidential campaigns, it's not unusual to hear candidates from both parties say they will focus on strengthening the nation's economy, but how well have presidents delivered on that promise once in the White House?
PHILADELPHIA – An international effort led by researchers at the Perelman School of Medicine at the University of Pennsylvania has resulted in positive phase 3 clinical trial results for a new medicine to treat patients suffering from a rare and deadly cholesterol disorder.
