People who take oral bisphosphonates for bone disease over five years may be doubling their risk of developing oesophageal cancer (cancer of the gullet), according to a new study published on bmj.com today.

Oral bisphosphonates are a type of drug used to treat osteoporosis and other bone diseases and are the most commonly recommended treatment for such conditions.

Interim results from the first comprehensive evaluation of the implementation of electronic health records in secondary care in England have found delays and frustration with the system, according to research published on bmj.com today.

DURHAM, N.C. – Millions of patients with advanced disease in palliative care settings receive oxygen therapy to help them breathe more easily. But a new study from Duke University Medical Center says roughly half of them don't benefit from the intervention, and among those who do benefit, it doesn't make a bit of difference whether they get pure oxygen or just plain old room air – both offer equal benefit.

Individuals who received a non-kidney organ transplant in the past may be more likely to be listed for a kidney transplant prior to initiation of dialysis (pre-emptive listing) than other candidates, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The results indicate that the growth in the numbers of this group of kidney transplant candidates adds to the list of organ allocation challenges.

Kidney transplants that show a combination of fibrosis (scarring) and inflammation after one year are at higher risk of long-term transplant failure, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

DURHAM, N.C. – Duke University Medical Center researchers have found two genes in mice which might help identify why some people are more susceptible than others to potentially deadly staph infections.

The researchers uncovered important genetic clues that ultimately could help inform patient management and drug development.

Montreal, September 3, 2010 – Dr. Éric A. Cohen, Director of the Human Retrovirology research unit at the Institut de recherches cliniques de Montréal (IRCM), and his team published yesterday, in the online open-access journal PLos Pathogens, the results of their most recent research on the role of the Vpr protein in HIV (human immunodeficiency virus) infection and AIDS (acquired autoimmune deficiency syndrome).

New models, reinforced by in vivo experimentation, show why 5-10% of bone fractures don't heal properly, and how these cases may be treated to restart the healing process. Results of the model, published September 2 in the open-access journal PLoS Computational Biology, may benefit the ageing population in which the occurrence of bone fractures is expected to rise substantially in the near future.

Singapore, September 3, 2010 — Novartis announced today that scientists at the Novartis Institute for Tropical Diseases (NITD), in collaboration with researchers from the Genomics Institute of the Novartis Research Foundation (GNF), the Swiss Tropical and Public Health Institute and The Scripps Research Institute have discovered a novel compound that shows promise as a next generation treatment for drug resistant malaria. Major support for the project was provided by the Wellcome Trust, the Medicines for Malaria Venture (MMV), A*STAR, Singapore and the U.S. government.

BIRMINGHAM, Ala. – Cigarette smoke shuts off a key enzyme in airways that regulates the body's response to inflammation, according to findings from the University of Alabama at Birmingham published online today at Science Express.

The UAB researchers say smoke inhibits the enzyme, called Leukotriene A4 Hydrolase (LTA4H), causing it to fail in its job of shutting down white blood cells following a successful response to inflammation.

ANN ARBOR, Mich. — School children who consume foods purchased in vending machines are more likely to develop poor diet quality – and that may be associated with being overweight, obese or at risk for chronic health problems such as diabetes and coronary artery disease, according to research from the University of Michigan Medical School.

The study also looked at foods sold in school stores, snack bars and other related sales that compete with USDA lunch program offerings and found that these pose the same health and diet risks in school-aged children.

LA JOLLA, CA – September 2, 2010 – Scripps Research Institute scientists have identified two proteins with potential to be important targets for research into a wide range of health problems, including pain, deafness, and cardiac and kidney dysfunction.

The study was published in Science Express, the advanced, online edition of the journal Science, on September 2, 2010.

A chemical that rid mice of malaria-causing parasites after a single oral dose may eventually become a new malaria drug if further tests in animals and people uphold the promise of early findings. The compound, NITD609, was developed by an international team of researchers including Elizabeth A. Winzeler, Ph.D., a grantee of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

LA JOLLA, CA – August 30, 2010 –– An international team led by scientists from The Scripps Research Institute, the Swiss Tropical Institute, the Genomics Institute of the Novartis Research Foundation and the Novartis Institute for Tropical Diseases has discovered a promising new drug candidate that represents a new class of drug to treat malaria. Clinical trials for the compound are planned for later this year.

The research was published on September 3, 2010, in the prestigious journal Science.
