The UK National Health Service could save millions of pounds a year by routinely using inexpensive dressings to treat venous leg ulcers, after a study published in the October issue of BJS showed that they are just as effective as expensive silver dressings in the majority of cases.

Researchers, led by Professor Jonathan Michaels from the Sheffield Vascular Institute and Professor Bruce Campbell from the Royal Devon and Exeter Hospital, studied 213 leg ulcer patients who received either standard low-adhesive dressings or antimicrobial silver-donating dressings.

Recently, at Arizona State University's Biodesign Institute, N.J. Tao and collaborators have found a way to make a key electrical component on a phenomenally tiny scale. Their single-molecule diode is described in this week's online edition of Nature Chemistry.

A team of scientists at the National Cancer Institute (NCI) in Bethesda, USA, says that studying pet dogs with cancer could yield valuable information on how to diagnose and treat human cancers. In this week's PLoS Medicine, the team discusses an ongoing initiative in which spontaneously occurring cancers in dogs are being studied to help inform the development of new cancer drugs, devices and imaging strategies for human cancer patients.

COLUMBUS, Ohio – Women abused by intimate partners suffer higher rates of a wide variety of doctor-diagnosed medical maladies compared to women who were never abused, according to a new study of more than 3,000 women.

Many of these health problems are not commonly understood as being associated with violence, such as abdominal pain, chest pain, headaches, acid reflux, urinary tract infections, and menstrual disorders.

Visual problems that cannot be corrected are associated with increased risk of death among individuals between the ages of 49 and 74, and all visual impairments may be associated with the risk of death in older adults, according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

Researchers analyzing the assembly of graphene (sheets of carbon only one atom thick) on a surface of iridium have found that the sheets grow by first forming tiny carbon domes. The discovery offers new insight into the growth of graphene layers and points the way to possible methods for assembling components of graphene-based computer circuits.

SALT LAKE CITY, Oct. 12, 2009 – University of Utah engineers showed that a wireless network of radio transmitters can track people moving behind solid walls. The system could help police, firefighters and others nab intruders, and rescue hostages, fire victims and elderly people who fall in their homes. It also might help retail marketing and border control.

A new technique in Magnetic Resonance Imaging dubbed "Hyper-SAGE" has the potential to detect ultra low concentrations of clincal targets, such as lung and other cancers. Development of Hyper-SAGE was led by one of the world's foremost authorities on MRI technology, Alexander Pines, a chemist who holds joint appointments with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley.

SAN FRANCISCO - Locally advanced breast cancer patients who received the same class of neoadjuvant chemotherapy were found to have no evidence of disease at the time of their surgery, or achieved pathological complete response, at the same rate regardless of race, according to researchers at The University of Texas M. D. Anderson Cancer Center.

CHICAGO (October 9, 2009) – A new study published in the October issue of the Journal of the American College of Surgeons shows that the establishment of an acute care surgery service can help surgeons at academic medical centers provide more timely care to the growing number of patients who are transferred from the emergency room or smaller hospitals and who require an immediate operation.

A comprehensive study has revealed, for the first time, the impact of swine flu on the health of the general public in Australia and New Zealand.

The lessons learned in Intensive Care Units (ICUs) across the two countries on the impact of the H1N1 (swine flu) virus are being shared with countries in the Northern Hemisphere to help them prepare for their upcoming flu season.

BOSTON – Leptin, a molecule linked with obesity, may play a crucial role in predicting poor prognosis from thyroid cancer, at least in the Middle Eastern region of the world, according to data presented at the American Association for Cancer Research Frontiers in Basic Cancer Research Meeting.

WASHINGTON -- NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions.

New York, NY, October 8, 2009—The cost and quality of health care, as well as access to care and health outcomes, continue to vary widely among states, according to the Commonwealth Fund Commission on a High Performance Health System's second state scorecard report released today. The states that led in the 2007 state scorecard generally continued to lead, often setting new benchmarks and widening the gap between leading and lagging states.
