New blood tests may detect pancreatic cancer more effectively

A new diagnostic tool developed by Van Andel Research Institute (VARI) scientists has shown promising results when used with patients of pancreatic cancer, one of the deadliest forms of cancer due to the difficulty of diagnosing it in its early stages. The method, which studies carbohydrate structures in the bloodstream, could lead to the development of blood tests that can detect cancer more effectively.

HIV/AIDS research initiative launched in South Africa

South Africa's Science and Technology Minister Naledi Pandor on Tuesday announced a government-sponsored research initiative that "aims to combat HIV and AIDS through scientific and technological research, the development of new drugs, diagnostic tests and vaccines," SAPA/IOL reports (7/28).

Depression missed and misidentified

A meta-analysis of more than 50,000 patients has shown that general practitioners (GPs) have great difficulty separating those with and without depression, with substantial numbers of missed and misidentified.

Health benefits tax gains support in Congress, opponents in business

"You can think of Congress's efforts to pay for health reform as being a little bit like a battle to slay a many-headed Hydra," writes the New York Times' economic columnist, David Leonhardt.

Current diagnostic tests for ovarian cancer woefully ineffective

A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests. Still, if that hurdle can be overcome, there is good reason to believe that testing could make a big difference: The window of opportunity for treating these clinically undetectable cancers before they become life threatening is surprisingly long: about four years.

Coronary calcium scoring may predict heart attack risk

Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease (CAD) using coronary calcium scoring, according to a study published in the online edition of Radiology.

Artificial intelligence used to diagnose metastatic cancer

When doctors are managing care for women with breast cancer, the information available to them profoundly influences the type of care they recommend. Knowing whether a woman's cancer has metastasized, for instance, directly affects how her doctors will approach treatment -- which may in turn influence the outcome of that treatment.

Smoking increases likelihood that pancreatic ductal adenocarcinoma will become metastatic

Smoking has once again been implicated in the development of advanced cancer. Exposure to nicotine by way of cigarette smoking may increase the likelihood that pancreatic ductal adenocarcinoma will become metastatic, according to researchers from the Kimmel Cancer Center at Jefferson.

Protein produced by gene fusion that may also be targeted for new prostate cancer therapies

Researchers from NewYork-Presbyterian Hospital/Weill Cornell Medical Center have discovered a new gene fusion that is highly expressed in a subset of prostate cancers.

Major depressive disorder redefined

Researchers from Rhode Island Hospital's department of psychiatry propose that the definition for major depressive disorder (MDD) should be shortened to include only the mood and cognitive symptoms that have been part of the definition in the Diagnostic and Statistical Manual of Mental Disorders (DSM) for the past 35 years.

FDA authorizes emergency use of another test for H1N1 flu virus

The U.S. Food and Drug Administration today announced it has issued an Emergency Use Authorization (EUA) for a another diagnostic test for the 2009 H1N1 influenza virus, whose spread has caused the virus to be characterized as a pandemic by the World Health Organization.

Identification of progressors in osteoarthritis by combining biochemical and MRI-based markers

A combination of biochemical and MRI markers will allow improved measurement of osteoarthritis (OA) progression. The biomarkers, described in BioMed Central's open access journal Arthritis Research and Therapy, will be useful for the design and interpretation of trials of new disease modifying drugs.

Implantable device offers continuous cancer monitoring

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but offer only a snapshot of the tumor at a single moment in time.

Brain imaging (MRI/PET) bring us closer to earlier detection of Alzheimer's

Changes in the brain measured with MRI and PET scans, combined with memory tests and detection of risk proteins in body fluids, may lead to earlier and more accurate diagnosis of Alzheimer's, according to new research reported today at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD 2009) in Vienna.

Overcoming the big ‘nanotech’ challenges

Whether in the fields of medicine, sustainable energy supply or environmental protection, without making use of nanotechnology we will not be capable of overcoming the challenges which the future presents. In parallel with these efforts, though, it is essential that we examine the new technology very carefully for potential risks, such as those presented by free nanoparticles.

Prostate cancer: current evidence weighs against population screening

The recent release of two large randomized trials suggests that if there is a benefit of screening, it is, at best, small, says a new report in CA: A Cancer Journal for Clinicians.

Carbon nanotubes continue to show promise in battle against cancer

Carbon nanotubes, one of the original engineered nanomaterials, also may prove to be among the most versatile, as numerous teams of investigators continue to develop novel nanotube-based therapeutic and diagnostic tools. Over the past month, three new research papers have highlighted the potential of nanotubes as weapons against cancer.
