(Press-News.org) AURORA, Colo. (March 23, 2015) - Discontinuing statin use in patients with late-stage cancer and other terminal illnesses may help improve patients' quality of life without causing other adverse health effects, according to a new study by led by researchers at the University of Colorado Anschutz Medical Campus and Duke University and funded by the National Institute of Nursing Research (NINR).
The finding, to be published in JAMA Internal Medicine on March 23, indicates that care for patients with advanced illness can be improved by discontinuing some therapies that are primarily preventive for other health concerns.
"There is an increasing evidence base that discontinuation of some therapies may be beneficial for selected patient populations," the authors write. Jean Kutner, MD, MSPH, professor of medicine at the University of Colorado School of Medicine, is the first author of the research study and Amy Abernethy, MD, PHD, of the Center for Learning Health Care at the Duke Clinical Research Institute, is the corresponding author.
Statins are among the most commonly prescribed medications in the United States with more than 25 percent of the nation's Medicare beneficiaries receiving statin therapy. These medications are usually taken to lower cholesterol and reduce the risk of heart attack or stroke. The benefits of statins typically take two years to accrue.
The study evaluated 381 patients. About half of them discontinued statins, while the other half continued the therapy. The average age of the patients was 74 years old and 48.8 percent of them had cancer. The median survival time for the entire study population was 219 days and the proportion of participants who died within 60 days was not significantly different between the groups that continued or discontinued statin therapy.
"If the results we report - improved quality of life, no significant differences in mortality, and modest cost savings - had been produced by a randomized clinical trial of a new drug in patients with advanced life-limiting illness, the trial would be heralded as a breakthrough and there would be discussion of how to speed access to this new drug," the authors write. "The same energy needs to be applied to determining when it is appropriate for physicians to discuss discontinuing statin therapy with their patients."
The study's results address significant concerns related to end-of-life health care. In the last year of life, the number of medicines increases by 50 percent, so reducing the number of medications may relieve the pill burden on some patients. Also, more than 80 percent of Americans are expected to die of chronic illnesses, primarily cardiovascular disease, cancer, dementia and chronic lung disease. Because statins are effective in primary prevention of cardiovascular disease, the number of patients on the therapy is expanding and it is frequently continued until the end of patients' life.
The authors say that their study should prompt physicians to discuss the uncertain benefit and possible harm of continuing statin therapy for people with life-liming illness and functional decline.
"For patients with shorter life expectancy, greater concern about pill burden, and more comfort-oriented goals of care," the authors conclude, "physicians may endorse discontinuing statins as a means to reduce the number of medications without apparent harmful effects on survival or quality of life."

A blood thinning agent is helping researchers at the University of East Anglia understand more about the body's natural barriers to HIV.
New research published today reveals how the protein langerin, which is present in genital mucous and acts as a natural HIV barrier during the first stages of contamination, interacts with the drug heparin.
The research team has been able to identify two different mechanisms for that interaction - involving different sites or 'faces' at the surface of the langerin protein.

Lexington, MA (March 23, 2015) - Research results published in the Journal of Neurotrauma and conducted by the Walter Reed Army Institute of Research (WRAIR) as part of a collaboration with Concert Pharmaceuticals, Inc. showed that a novel deuterium-containing sigma-1 agonist invented at Concert, called C-10068, demonstrated anti-seizure and anti-inflammatory effects in a preclinical model of traumatic brain injury (TBI). C-10068, a novel metabolically-stabilized morphinan derivative, is based on a compound first identified at WRAIR in the 1990s as possessing anticonvulsant ...
Many smartphone users know that free apps sometimes share private information with third parties, but few, if any, are aware of how frequently this occurs. An experiment at Carnegie Mellon University shows that when people learn exactly how many times these apps share that information they rapidly act to limit further sharing.
In one phase of a study that evaluated the benefits of app permission managers - software that gives people control over what sensitive information their apps can access - 23 smartphone users received a daily message, or "privacy nudge," telling ...
March 23, 2015 - Patients with carpal tunnel syndrome are more than twice as likely to have migraine headaches, reports a study in Plastic and Reconstructive Surgery--Global Open®, the official open-access medical journal of the American Society of Plastic Surgeons (ASPS).
The association also runs in the other direction, with migraine patients having higher odds of carpal tunnel syndrome, according to research by Dr. Huay-Zong Law and colleagues of University of Texas Southwestern Medical Center at Dallas. The findings add a new piece of evidence in the ongoing debate ...
This news release is available in French. Raising the age of eligibility for the Old Age Security pension and the Guaranteed Income Supplement will increase inequalities between older people. "This change will force retired people into greater dependence on their private savings to support them as they get older. Research shows that greater privatisation of the retirement income system results in growing inequalities among the older population. When you raise the pension eligibility age, you are also opening the door to rising disparities" according to demographer Yves ...
Implementing a well-established business approach allowed physicians to shave hours off pediatric patient discharges without affecting readmission rates, according to researchers at Penn State Hershey Children's Hospital.
This approach could help hospitals around the country open up existing beds to more patients, and reduce emergency department crowding and lost referrals without investing significant capital.
Most hospitals have a fixed number of staffed beds available for patients. When hospitals are at or exceed capacity, admitted patients may be kept in the ED ...
An extensive study of global habitat fragmentation - the division of habitats into smaller and more isolated patches - points to major trouble for a number of the world's ecosystems and the plants and animals living in them.
The study shows that 70 percent of existing forest lands are within a half-mile of the forest edge, where encroaching urban, suburban or agricultural influences can cause any number of harmful effects - like the losses of plants and animals.
The study also tracks seven major experiments on five continents that examine habitat fragmentation ...
NAIROBI, KENYA (20 March 2015)--African cattle infected with a lethal parasite that kills one million cows per year are less likely to die when co-infected with the parasite's milder cousin, according to a new study published today in Science Advances. The findings suggest that "fighting fire with fire" is a strategy that might work against a range of parasitic diseases.
The immediate implications are for the battle in Africa against a tick-borne cattle-killing parasite, Theileria parva, which causes East Coast fever. The disease kills one cow every 30 seconds and claims ...
PHILADELPHIA- Penn Medicine researchers have discovered that hypermethylation - the epigenetic ability to turn down or turn off a bad gene implicated in 10 to 30 percent of patients with Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Degeneration (FTD) - serves as a protective barrier inhibiting the development of these diseases. Their work, published this month in Neurology, may suggest a neuroprotective target for drug discovery efforts.
"This is the first epigenetic modification of a gene that seems to be protective against neuronal disease," says lead author ...
