Heart failure patients with depression have 4 times risk of death

American Heart Association Rapid Access Journal Report

2013-03-20

(Press-News.org) Heart failure patients who are moderately or severely depressed have four times the risk of dying and double the risk of having to go to the emergency room or be hospitalized compared to those who are not depressed, according to new research reported in Circulation: Heart Failure, an American Heart Association Journal. "Depression is a key driver of healthcare use in heart failure," said Alanna M. Chamberlain, Ph.D., M.P.H., the study's lead author and assistant professor of epidemiology in the Department of Health Sciences Research at the Mayo Clinic in Rochester, Minn. "Treatment programs should be tailored to each patient's needs with greater emphasis on managing depression either through medication or lifestyle interventions." In 2007-10, 402 heart failure patients (58 percent male, average age 73) in three Minnesota counties completed a nine-question survey. Based on the answers, 59 percent of patients were classified as having no depression, 26 percent had mild depression and 15 percent had moderate-to-severe depression. Researchers gathered information on the participants for about a year and a half. Even those who reported mild depression had almost a 60 percent increased risk of death, but a much smaller increased risk of emergency room visits (35 percent) and hospitalizations (16 percent), researchers found. Because the patients studied were mostly white and lived in southeastern Minnesota, the results may not apply to all heart failure patients throughout the United States, researchers said. Only a third of the patients with moderate-to-severe depression were taking antidepressant medication. Depression may be underdiagnosed in these patients; however, some may have been undergoing therapy that didn't include prescription drugs, researchers said. "We measured depression with a one-time questionnaire so we cannot account for changes in depression symptoms over time," Chamberlain said. "Further research is warranted to develop more effective clinical approaches for management of depression in heart failure patients." ### Co-authors are: Amanda R. Moraska, B.A.; Nilay D.

Anxiety, depression identify heart disease patients at increased risk of dying

2013-03-20

Heart disease patients who have anxiety have twice the risk of dying from any cause compared to those without anxiety, according to new research in the Journal of the American Heart Association. Patients with both anxiety and depression have triple the risk of dying, researchers said. "Many studies have linked depression to an increased risk of death in heart disease patients," said Lana Watkins, Ph.D., lead author of the study and an associate professor in Psychiatry and Behavioral Sciences at Duke University Medical Center in Durham, N.C. "However, anxiety hasn't received ...

Sexually naïve male mice, fathers respond differently to pups

2013-03-20

Washington, DC — Sexually naïve male mice respond differently to the chemical signals emitted by newborn pups than males that have mated and lived with pregnant females, according to a study published March 20 in The Journal of Neuroscience. The findings may help scientists to better understand the changes that take place in the brains of some mammals during the transition into parenthood. Sex differences in the behaviors mice display toward newborn pups are well documented. While virgin female mice routinely provide parental care to pups upon first encounter, ...

High potency statins pose significantly higher risk of kidney injury than low potency, say experts

Research: Use of high potency statins and rates of admission for acute kidney injury: multicenter, retrospective observational analysis of administrative databases Editorial: Statins in acute kidney injury: friend or foe? Patients taking high potency statins for high blood pressure are at a 34% higher risk of being hospitalised for acute kidney injury (AKI), compared with those taking low potency statins, a paper published today on bmj.com suggests. The use of statins is often recommended to reduce the risk of cardiovascular disease among high risk patients. However, ...

New disorder could classify millions of people as mentally ill

2013-03-20

Personal View: The new somatic symptom disorder in DSM-5 risks mislabeling many people as mentally ill Millions of people could be mislabeled as mentally ill when psychiatry's bible of diagnoses is updated in May, warns a senior doctor in this week's BMJ. The next edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-5) – used around the world to classify mental disorders - will include a new category of somatic symptom disorder. But Allen Frances, Chair of the current (DSM-IV) task force warns that the DSM-5 ...

Studies for approval of new drugs have insufficient patients to evaluate safety

2013-03-20

For medicines intended for chronic use, the number of patients studied before regulatory approval is insufficient to properly evaluate safety and long-term efficacy, requiring the need for new legislation, according to a study by European researchers published in this week's PLOS Medicine. Current European guidelines specify that in order to fully evaluate the safety of medicines being developed for chronic (long-term) treatment of non-life threatening diseases, at least 1000 patients must take the new drug and that 300 and 100 patients must use the drug for 6 and 12 ...

African immunization systems fall short, African experts say

2013-03-20

In Africa, issues of vaccine supply, financing, and sustainability require urgent attention if the Millennium Development Goals are to be achieved, according to African experts writing in this week's PLOS Medicine. Shingai Machingaidze, Charles Wiysonge, and Gregory Hussey from the University of Cape Town in South Africa commend African countries for their progress in immunisation programmes but infectious disease outbreaks, for example, polio and measles outbreaks, as well as high vaccine dropout rates across the region, indicate failures within the immunisation system. ...

For polar bears, it's survival of the fattest

2013-03-20

One of the most southerly populations of polar bears in the world – and the best studied – is struggling to cope with climate-induced changes to sea ice, new research reveals. Based on over 10 years' data the study, published in the British Ecological Society's Journal of Animal Ecology, sheds new light on how sea ice conditions drive polar bears' annual migration on and off the ice. Lead by Dr Seth Cherry of the University of Alberta, the team studied polar bears in western Hudson Bay, where sea ice melts completely each summer and typically re-freezes from late November ...

Caffeine 'can significantly protect against crash risk' for long distance heavy vehicle drivers

2013-03-20

Research: Use of caffeinated substances and risk of crashes in long distance drivers of commercial vehicles: case-control study Long distance commercial drivers who consume caffeinated substances such as coffee or energy drinks, to stay awake while driving, are significantly less likely to crash than those who do not, even though they drive longer distances and sleep less, finds a study published today on bmj.com. Long distance drivers routinely experience monotonous and extended driving periods in a sedentary position, which has been associated with wake time drowsiness, ...
