PITTSBURGH -- Twitter users choose the microblogs they follow, but that doesn't mean they always like what they get. Researchers at Carnegie Mellon University, the Massachusetts Institute of Technology and the Georgia Institute of Technology found that users say only a little more than a third of the tweets they receive are worthwhile.

Other tweets are either so-so or, in one out of four cases, not worth reading at all.

Even if the current weather situation may seem to speak against it, the probability of cold winters with much snow in Central Europe rises when the Arctic is covered by less sea ice in summer. Scientists of the Research Unit Potsdam of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association have decrypted a mechanism in which a shrinking summertime sea ice cover changes the air pressure zones in the Arctic atmosphere and impacts our European winter weather.

In an effort to reduce the inappropriate use of medical imaging and improve quality of care, a large, tertiary-care hospital has successfully implemented a computerized physician order entry (CPOE) system with clinical decision support for radiology, according to a study in the February issue of the Journal of the American College of Radiology.

Comprehensive work studying the burden of ill-health and death resulting from specific conditions, injuries, and risk factors—the Global Burden of Disease project—has shown that the burden of ill-health around the world is highly inequitable. In this week's PLoS Medicine, the editors review progress towards the journal's goal of reflecting and addressing this inequity.

CHICAGO – Compliance with proposed emergency department length of stay measures for admitted, discharged, transferred, and observed patients does not differ significantly between safety-net hospitals (which serve higher proportion of patients with poorer health care status) and non-safety-net hospitals, addressing the issue of whether safety-net hospitals may not be able to meet certain performance measures and could be at risk of reduced funding, according to a study in the February 1 issue of JAMA.

Time can be important in an emergency department especially in a busy Level 1 Trauma Center like MetroHealth Medical Center in Cleveland, when getting patients appropriate care is essential. However, when the quality of an emergency department is judged by a patient's length of stay, time takes on a new meaning.

A study published in The Journal of the American Medical Association (JAMA) found that there is no significant difference between safety-net and non-safety-net hospitals when it comes to the length of stay for emergency patients.

Philadelphia, PA, January 31, 2011 – Back problems are a highly prevalent health issue, and people with the condition have a significantly greater chance of retiring early from the workforce, much more so than for any other health condition. A group of Australian researchers reports that not only does early retirement limit the immediate income available to these individuals, but it also reduces their long-term financial capacity, by reducing their ability to accumulate wealth to a significant degree. Their study is published in the January issue of Pain®.

The pain suffered by older adults is the shared focus of the two newest entries in The Gerontological Society of America's (GSA) From Publication to Practice series. Together they address both pain management and new labeling changes for one of the most popular pain medications, acetaminophen.

Internet users are increasingly asked to register with a user name and password before being able to access the content of many sites. In their upcoming Ergonomics in Design article, "A Passport to UX – Design of Password Practices," human factors/ergonomics researchers Soolmaz Moshfeghian and Young Sam Ryu identify impediments to efficient password creation and provide design strategies for enhancing the user experience.

School administrators are facing a growing dilemma resulting from social networking that goes beyond preventing cyber-bullying among students. They're also faced with balancing the rights of privacy and free speech of educators with what should be the appropriate behavior of teachers as role models.

ITHACA, N.Y. — For those with few social advantages, college is a prime pathway to financial stability, but it also unexpectedly lowers their odds of ever marrying, according to a study by Cornell University sociologist Kelly Musick being published in the February issue of the Journal of Marriage and Family (available online: http://bit.ly/yt9uwJ).

Levels of burnout in UK general practice are high, suggests a study of general practitioners (GPs) in one area of South East England, published in BMJ Open.

Male doctors, those who work in group practices, and those who repeatedly see the same patients seem to be at significantly greater risk, the research shows, prompting the authors to declare that "a significant group of doctors is in trouble."

Sophia Antipolis -- The European Society of Cardiology (ESC) welcomes an "intriguing" study, published today in the Journal of the American College of Cardiology, featuring a completely novel approach for improving endothelial function in heart failure¹. In the "hypothesis generating" study, ursodeoxycholic acid (UDCA) delivered significant improvements in peak post ischemic blood flow in the arm, a trend for improvement in peak post ischemic blood flow in the leg, but failed to show benefits in exercise capacity and several inflammatory markers.

WASHINGTON, DC (January 30, 2012) – Updated appropriate use criteria released today offer detailed guidance on when to use an invasive procedure to improve blood flow to the heart and how to choose the best procedure for each patient. The clinical scenarios, written by a group of cardiologists and cardiac surgeons, affirm the role of revascularization for patients with acute coronary syndromes and significant symptoms.

More research and programs are needed to address the elevated rate of motor vehicle-related deaths among American Indian and Alaska Native populations, according to new research from the Johns Hopkins Center for Injury Research and Policy. To better understand this racial and ethnic disparity, the authors conducted a systematic review of literature published over the past twenty years and found just seven studies describing the problem, and only seven that tested interventions.
