Closer to vaccine against C. difficile Posted: 04 Nov 2013 04:22 PM PST A group of leading scientists from across Europe have launched a three-year project aimed at developing an oral vaccine against Clostridium difficile, an infection that kills 4,000 people a year (almost four-times more than MRSA) and for which there is currently no effective treatments.

New strep throat risk score brings data together to improve care Posted: 04 Nov 2013 02:13 PM PST A new risk measure called a "home score" could save a patient with symptoms of strep throat a trip to the doctor, according to a new paper. The score combines patients' symptoms and demographic information with data on local strep throat activity to estimate their strep risk, empowering them to seek care appropriately.

Reduce unnecessary lab tests, decrease costs by modifying software Posted: 04 Nov 2013 01:27 PM PST When patients undergo diagnostic lab tests as part of the inpatient admission process, they may wonder why or how physicians choose particular tests. Increasingly, medical professionals are using electronic medical systems that provide lists of lab tests from to choose. Now, researchers have studied how to modify these lists to ensure health professionals order relevant tests and omit unnecessary lab tests, which could result in better care and reduced costs.

Cutting-edge detector technology for astronomical observations developed Posted: 04 Nov 2013 01:27 PM PST Semiconductors have had a nice run, but for certain applications, such as astrophysics, they are being edged out by superconductors. Scientists have now developed a superconducting detector array that measures the energy of individual photons.

Foreign-educated health workers play vital role in US health system Posted: 04 Nov 2013 01:27 PM PST Foreign-educated and foreign-born health professionals play a vital role in the US health care workforce, particularly in addressing needs in primary care and other areas with worker shortages, according to a new study. However, there is no cohesive national strategy on the issue, which may contribute to a less-stable US health care workforce.

Eating disorders more common in males than realized Posted: 04 Nov 2013 01:25 PM PST Parents and doctors assume eating disorders very rarely affect males. However, a study of 5,527 teenage males from across the US challenges this belief. Researchers found 17.9 percent of adolescent boys were extremely concerned about their weight and physique. These boys were more likely to start engaging in risky behaviors, including drug use and frequent binge drinking.

Researchers offer solutions to looming healthcare provider shortage Posted: 04 Nov 2013 01:25 PM PST Thanks to a wave of aging baby boomers, epidemics of diabetes and obesity, and the Affordable Care Act, which aims to bring health care coverage to millions more Americans, the United States faces a severe shortage of primary health care providers. In a series of papers published in the November 2013 issue of Health Affairs, researchers at UC San Francisco advocated a number of potential solutions to the problem.

Physician shortage could be cut by new primary care models Posted: 04 Nov 2013 01:25 PM PST The US expects a substantial shortages of primary care physicians in the future. A new study finds that much of that gap could be eliminated if the nation increases use of new models of care that expand the role of nurse practitioners and physician assistants. Under plausible expansion scenarios, patient-centered medical homes and nurse-managed health centers could eliminate 50 percent or more of the primary care physician shortage by 2025.

Solving pediatric obesity problem in rural communities Posted: 04 Nov 2013 01:25 PM PST Using telemedicine to unite clinicians and provide health education for them -- and by extension, their patients -- is an effective way to manage childhood obesity in remote areas.

Electronic, internet health tools may decrease in-person physician visits Posted: 04 Nov 2013 01:23 PM PST An analysis of recent trends in digital health care and a review of the scientific literature suggests patients' future use of physician services will change dramatically as electronic health records and consumer e-health "apps" proliferate.

Women, African-Americans at higher risk of heart attack from atrial fibrillation Posted: 04 Nov 2013 01:23 PM PST Doctors have known for years that atrial fibrillation (AF), or irregular heartbeat, increases the risk for stroke, but now researchers have shown that it also increases the risk for heart attack. In fact, for women and African Americans, it more than doubles the risk.

Repetition of rare events could reduce screening mistakes by security Posted: 04 Nov 2013 12:27 PM PST The failure to detect infrequent, but obvious security threats at airport screenings and other checkpoints may have less to do with incompetence or poor training than a human tendency to overlook rare events. But a researcher suggests guards could improve their detection rates the same way adults learn vocabulary words -- through repetition.

A better way to track your every move: Algorithm accurately tracks physical activity no matter where you carry your phone Posted: 04 Nov 2013 12:27 PM PST Physical activity tracking apps on smartphones are a potentially important tool for doctors who want to collect data and create treatment or intervention plans to improve the health of patients who struggle with activity and movement -- such as those with Parkinson's disease.

Wives matter more when it comes to calming down marital conflicts Posted: 04 Nov 2013 12:27 PM PST Marriage can be a battlefield. But a new study has found that, when it comes to keeping the peace, it's more important for wives -- than for husbands -- to calm down after a heated argument.

Now, a researcher demonstrates that, unlike the Near Eastern wild boars in surrounding countries, Israel's wild boars originated in Europe, brought to Israel starting almost 3,000 years ago by the Philistines and other seafaring raiders.

Gas injection probably triggered small earthquakes near Snyder, Texas Posted: 04 Nov 2013 12:27 PM PST A series of small earthquakes near Snyder, Texas between 2006 and 2011 were probably triggered by the underground injection of large volumes of gas, primarily carbon dioxide -- a finding that has implications for the process of carbon capture and storage. Experts also note that similar rates of injections have not triggered comparable quakes in other fields, bolstering the idea that gas injection does not cause significant seismic events in many geologic settings.

One in five stars may have Earth-size, potentially habitable planets Posted: 04 Nov 2013 12:27 PM PST Astronomers analyzed all four years of Kepler data in search of Earth-size planets in the habitable zones of sun-like stars, and then rigorously tested how many planets they may have missed. Based on this analysis, they estimate that 22 percent of stars like the sun have potentially habitable Earth-size planets, though not all may be rocky or have liquid water, a presumed prerequisite for life.

Fossil of largest known platypus discovered in Australia Posted: 04 Nov 2013 12:27 PM PST Until recently, the fossil record indicated that the platypus lineage was unique, with only one species inhabiting the Earth at any one time. This picture has changed with the spectacular find of a new, giant species of extinct platypus that was a side-branch of the platypus family tree.
