Blacks have highest cancer rates of all racial ethnicities, yet feel less at risk, study finds

BUFFALO, N.Y. -- Mammograms, pap smears and early detection tests for prostate cancer, colorectal cancer and other malignancies are critical for catching cancer before it becomes deadly.

However, a new study by University at Buffalo researchers shows that persons of different ethnic groups have different ideas and opinions about whether they are at risk for developing cancer -- perceptions that can influence whether they undergo screening.

Study points to potential new drug for type 2 diabetes

COLUMBUS, Ohio – An experimental oral drug has lowered blood sugar levels and inflammation in mice with Type 2 diabetes, suggesting that the medication could someday be added to the arsenal of drugs used by millions of Americans with this disease, according to new research.

The drug consists of a synthetic molecule that stops the biological activity of a protein called macrophage migration inhibitory factor, or MIF. This protein is implicated in a number of diseases because it is associated with the production of inflammation in the body.

Studies provide more support for health benefits of coffee

Multitudes of people worldwide begin each day with a cup of steaming hot coffee. Although it is sometimes referred to as "the devil's brew," coffee contains several nutrients (eg, calcium) as well as hundreds of potentially biologically active compounds (eg, polyphenols) that may promote health. For instance, observational studies have suggested a beneficial link between coffee consumption and type 2 diabetes. Determining whether or not this association is causative, however, requires controlled intervention trials.

Light-activated 'warhead' turns modest molecules into super protein killers

JUPITER, FL, March 10, 2010 –– Using a novel light activation technique, Scripps Research Institute scientists have been able to turn molecules with only a modest ability to fight specific proteins into virtual protein destroyers.

The new technique, which uses a "warhead" molecule capable of inactivating nearby proteins when triggered by light, could help to accelerate the development of new therapies by providing researchers with a new set of research tools and options.

How plants put down roots

In the beginning is the fertilized egg cell. Following numerous cell divisions, it then develops into a complex organism with different organs and tissues. The largely unexplained process whereby the cells simply "know" the organs into which they should later develop is an astonishing phenomenon. Scientists from the Center for Plant Molecular Biology (ZMBP) of the University of Tübingen and the University of Wageningen, in cooperation with colleagues from the Max Planck Institute for Developmental Biology, have investigated how this process is controlled.

To the Antarctic or Brazil for new feathers

Not only land birds, but also some seabirds, cover enormous distances during migration: the sooty shearwater, for example, circumnavigates the earth one and a half times on its travels. Despite this, relatively little is known about the migratory behaviour of seabirds as compared with that of their land-living counterparts. Scientists from the Max Planck Institute for Ornithology have studied the migratory behaviour of thin-billed prions and discovered that the animals spend their moulting season in two areas that are at a considerable distance from each other.

Mayo Clinic study on how to minimize radiation risks of angioplasty shows highest doses in men

ATLANTA - Body size, gender and the complexity of heart disease significantly influence how much cumulative radiation skin dose that patients receive during percutaneous coronary intervention (PCI) therapy, also known as angioplasty, according to a new Mayo Clinic study. The study was undertaken as a quality control initiative to reduce the potential radiation risks of cancer to patients and PCI operators.

Dying cancer patient visits to emergency departments can be avoided

Many visits by dying cancer patients to the emergency department can be avoided with effective palliative care, states an article in the Canadian Medical Association Journal (CMAJ) (pre-embargo link only)http://www.cmaj.ca/embargo/cmaj091187.pdf. In Ontario, about 40% of cancer patients visit the emergency department in the last 2 weeks of life.

Private drinking water supplies pose challenges to public health

An estimated three to four million people – about one in every eight Canadians –drink water from private supplies.

Inappropriate uses of frozen plasma

Large amounts of frozen plasma are being used inappropriately, states a commentary in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj081933.pdf.

There has been increased attention given to the clinical use of red blood cells and platelets but not enough has been paid to the use of frozen plasma.

Driving retirement for seniors

Public safety should win against personal choice especially when it comes to elderly seniors who shouldn't drive, states an editorial in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj100273.pdf.

Seniors can be the safest drivers but that decreases with age as a growing number of medical conditions can lower a person's ability to drive.

By 2025, one in four Canadians will be 65 or older.

Baby's obesity risk: What's the mother's influence?

Aspiring moms may be advised to achieve a healthy weight before they become pregnant, and to gain only the recommended amount of weight during their pregnancy. Now ongoing studies by Agricultural Research Service (ARS)-funded investigator Kartik Shankar and colleagues could provide new insights into those recommendations.

Shankar is taking a new, closer look at how influences that occur in the womb–and perhaps during the first few months of life–might affect development of a child's ability to regulate his or her weight later in life.

Amniotic fluid cells more efficiently reprogrammed to pluripotency than adult cells

In a breakthrough that may help fill a critical need in stem cell research and patient care, researchers at Mount Sinai School of Medicine have demonstrated that skin cells found in human amniotic fluid can be efficiently "reprogrammed" to pluripotency, where they have characteristics similar to human embryonic stem cells that can develop into almost any type of cell in the human body. The study is online now and will appear in print in the next issue of the journal Cellular Reprogramming, to be published next month.

Palpable breast cancers are more common in women not undergoing annual mammography

CHICAGO (March 15, 2010) – New research findings published in the March issue of the Journal of the American College of Surgeons indicate that some breast cancers continue to be detected as a palpable lump rather than being found through mammographic screening. Patients who presented with palpable tumors – those detected as a result of breast complaint or during examination – had larger tumors and were at a more advanced stage at diagnosis.

Insurance status of gunshot trauma patients affects mortality outcomes

CHICAGO (March 15, 2010) – New research findings published in the March issue of the Journal of the American College of Surgeons indicates that despite similar injury severity, uninsured patients were significantly more likely to die after hospital admission for gunshot injury than were insured patients. This difference could not be attributed to demographics or hospital resource use, and held true even after adjusting for the effects of race, age, gender, and injury severity.
