New NIST nanoscale indenter takes novel approach to measuring surface properties

Researchers from the National Institute of Standards and Technology (NIST) and the University of North Carolina have demonstrated a new design for an instrument, a "instrumented nanoscale indenter," that makes sensitive measurements of the mechanical properties of thin films -- ranging from auto body coatings to microelectronic devices -- and biomaterials. The NIST instrument uses a unique technique for precisely measuring the depth of the indentation in a test surface with no contact of the surface other than the probe tip itself.*

Trust in physician eases talks about medical expenses

Strong relationships with physicians, particularly those that are long standing, are likely to increase patients' openness to talk about health care costs when decisions are being made about their treatment options. According to a new study1 by Marion Danis from the National Institutes of Health Clinical Center2 in the US, and colleagues, rushed visits with insufficient time to talk about important issues can undermine efforts to bring sensitive topics like costs into the doctor-patient relationship and can be counterproductive.

Hospital mammography recall rates higher

OAK BROOK, Ill. – The rate at which women get called back for additional imaging after screening mammography may be higher at hospitals than at community office practices, mostly due to differences among the patients, according to a new study published online in the journal Radiology. The findings highlight the limitations of recall rates as a quality measure for breast cancer screening, the researchers said.

RI Hospital study finds differences in mammography recall rate between 2 centers

PROVIDENCE, R.I. – A new study at Rhode Island Hospital has found that academic medical centers have higher rates of recall following mammography than community radiology centers. The recall rate is the frequency at which a radiologist interprets an examination as positive and the patient is instructed to return for more testing. The study is published online in advance of print in the journal Radiology.

Barriers to interventions to prevent malaria in pregnancy similar across sub-Saharan Africa

The main barriers to the access, delivery, and use of interventions that help to prevent malaria in pregnant women are relatively consistent across sub-Saharan African countries and may provide a helpful checklist to identify the factors influencing uptake of these important interventions, according to a study published in this week's PLOS Medicine.

Researcher develops peer-led program to help individuals with HIV adhere to treatment plans

COLUMBIA, Mo. –Individuals diagnosed with HIV nowadays can live long, healthy lives if they follow their medical treatment plans; however, nearly half of individuals with the virus fail to get needed medical help or to continue treatment, according to previous research. Now, a nursing researcher at the University of Missouri has developed a peer-led intervention that helps individuals with HIV adhere to their treatment plans that can improve their quality of life.

Survey assesses views of physicians regarding controlling health care costs

In a survey of about 2,500 U. S. physicians on their perceived role in addressing health care costs, they reported having some responsibility to address health care costs in their practice and expressed general agreement with quality initiatives that may also reduce cost, but expressed less enthusiasm for cost containment involving changes in payment models, according to a study in the July 24/31 issue of JAMA.

Kidney stones associated with modest increased risk of coronary heart disease in women, but not men

An analysis of data from three studies that involved a total of more than 240,000 participants found that a self-reported history of kidney stones was associated with a statistically significant increased risk of coronary heart disease among women but no significant association was evident for men, according to a study in the July 24/31 issue of JAMA.

Mayo Clinic-led study: US physicians, patients' best interests, health care costs

ROCHESTER, Minn. — A new study of attitudes about health care costs reveals that an overwhelming majority of U.S. physicians feel a responsibility to address costs, but prioritize their obligations to patients' best interests over cost concerns. Results of the random survey of 2,500 U.S. physicians are published in this week's Journal of the American Medical Association (JAMA).

When bar fights get mean, bystanders intervene

People are more likely to try to break up a bar fight when they believe the conflict is too violent, or has the potential to become more violent, according to an international team of researchers.

Bystanders break up about a third of the fights that occur in bars and are most likely to intervene in conflicts between males, said Michael Parks, who recently earned his doctorate in sociology at Penn State.

Faster, simpler diagnosis for fibromyalgia may be on the horizon

COLUMBUS, Ohio – Researchers have developed a reliable way to use a finger-stick blood sample to detect fibromyalgia syndrome, a complicated pain disorder that often is difficult to diagnose.

If it were someday made available to primary care physicians, the test could knock up to five years off of the wait for a diagnosis, researchers predict.

In a pilot study, the scientists used a high-powered and specialized microscope to detect the presence of small molecules in blood-spot samples from patients known to have fibromyalgia.

Loopholes in health care law could result in employee harassment

CHAMPAIGN, Ill. — The contrasting incentives of employers and employees under the Affordable Care Act ultimately may result in increased employee harassment and retaliation claims, two University of Illinois law professors say in a paper they co-wrote.

As firms grapple with the significant cost increases associated with the new health care legislation, the possibility emerges that employers would harass or retaliate against employees in order to avoid the law's financial penalties, according to Peter Molk and Suja A. Thomas.

Oldest European fort in the inland US discovered in Appalachians

ANN ARBOR—The remains of the earliest European fort in the interior of what is now the United States have been discovered by a team of archaeologists, providing new insight into the start of the U.S. colonial era and the all-too-human reasons spoiling Spanish dreams of gold and glory.

Spanish Captain Juan Pardo and his men built Fort San Juan in the foothills of the Appalachian Mountains in 1567, nearly 20 years before Sir Walter Raleigh's "lost colony" at Roanoke and 40 years before the Jamestown settlement established England's presence in the region.

Significant other's excessive fears can compromise patient's recovery from SAH

Charlottesville, VA (July 23, 2013). Researchers from Durham University and Kings College London (United Kingdom) and the University of Erlangen-Nürnberg (Germany) found that patients who have suffered a subarachnoid hemorrhage (SAH) may not recover psychosocially as well as expected if their significant other is excessively fearful about the possibility of SAH recurrence. The researchers' findings are discussed in "Family and friends' fears of recurrence: impact on the patient's recovery after subarachnoid hemorrhage. Clinical article," by Judith Covey, Ph.D., Adam J.

Integrative medicine interventions found to significantly reduce pain, improve quality of life

An integrative approach to treating chronic pain significantly reduces pain severity while improving mood and quality of life, according to a new study from the Bravewell Practice-Based Research Network (BraveNet) published last month in BioMed Central Complementary and Alternative Medicine journal. Researchers found a reduction in pain severity of more than 20 percent and a drop in pain interference of nearly 30 percent in patients after 24 weeks of integrative care. Significant improvements in mood, stress, quality of life, fatigue, sleep and well-being were also observed.
