The Continuing Challenges In Changing Behaviors That Increase Cancer Risk
Date: Apr-15-2013An annual report from the American Cancer Society finds continuing challenges in changing behaviors and risk factors in order to reduce suffering and death from cancer. The report, Cancer Prevention & Early Detection Facts & Figures (CPED) 2013, outlines the current prevalence of tobacco use, obesity, physical inactivity, and the use of established screening tests, and emphasizes that social, economic, and legislative factors profoundly influence the individual health behaviors that contribute to cancer risk...
Avandia Safety Being Reconsidered By FDA Panel
Date: Apr-15-2013Despite GlaxoSmithKline saying it does not plan to make almost-discontinued diabetes drug Avandia available in the USA, the FDA's Endocrinologic and Metabolic advisory panel along with the FDA's Drug Safety and Risk Management Advisory committee will consider the medication's safety in June 2013. In September 2010, the FDA (Food and Drug Administration) severely restricted Avandia usage, and ordered GlaxoSmithKline to convene an independent group of scientists to re-check data on the drug's clinical trials...
Tool Helps Governments Decide Whether Or Not To Screen Airline Passengers Leaving Or Arriving From Areas Of Infectious Disease Outbreaks
Date: Apr-15-2013Researchers have developed a simple new tool to help governments worldwide decide whether to screen airplane passengers leaving or arriving from areas of infectious disease outbreaks. The tool was developed by examining all international airplane traffic in the initial stages of the 2009 H1N1 pandemic. Researchers led by Dr. Kamran Khan of St. Michael's Hospital in Toronto found that that a focused and coordinated approach to screening airplane passengers would generate the greatest public health benefits...
Salmonella More Resilient Than Originally Thought
Date: Apr-15-2013Virginia Tech scientists have provided new evidence that biofilms - bacteria that adhere to surfaces and build protective coatings - are at work in the survival of the human pathogen Salmonella. One out of every six Americans becomes ill from eating contaminated food each year, with over a million illnesses caused by Salmonella bacteria, according to the Centers for Disease Control and Prevention. Finding out what makes Salmonella resistant to antibacterial measures could help curb outbreaks...
Analysis Of A Novel Adenovirus May Predict The Next Eye Pathogen
Date: Apr-15-2013The ongoing dance between a virus and its host distinctly shapes how the virus evolves. While human adenoviruses typically cause mild infections, recent reports have described newly characterized adenoviruses that can cause severe, sometime fatal, human infections...
Stimulant DMAA Potentially Dangerous To Health, FDA Warns
Date: Apr-15-2013The U.S. Food and Drug Agency (FDA) is currently doing everything it can to cancel the distribution and sale of all dietary supplements containing a stimulant commonly used for weight loss called dimethylamylamine (DMAA). DMAA is an organic compound used in products that cause weight loss or muscle development. However, the ingredient can cause serious side effects, such as: High blood pressure Heart attack Trouble breathing Tightening of the chest There have been a total of 86 cases of illness or death related to DMAA consumption, according to the FDA...
Improved Understanding Of How Phantom Sensations Are Produced By The Brain, Phantom Pain In Amputees
Date: Apr-15-2013The sensation of having a physical body is not as self-evident as one might think. Almost everyone who has had an arm or leg amputated experiences a phantom limb: a vivid sensation that the missing limb is still present. A new study by neuroscientists at the Karolinska Institutet in Sweden shows that it is possible to evoke the illusion of having a phantom hand in non-amputated individuals. In an article in the scientific periodical Journal of Cognitive Neuroscience, the researchers describe a perceptual illusion in which healthy volunteers experience having an invisible hand...
Seniors In Southern US At Increased Risk For Inappropriate Med Prescribing
Date: Apr-15-2013More than 1 in 5 seniors with Medicare Advantage plans received a prescription for a potentially harmful "high risk medication" in 2009, according to a newly published analysis by Brown University public health researchers. The questionable prescriptions were significantly more common in the Southeast region of the country, as well as among women and people living in relatively poor areas...
Therapeutic Potential Of SiRNA Drugs Boosted By Nanoparticles
Date: Apr-15-2013New classes of drugs that can silence specific genes, such as small interfering RNAs (siRNAs), offer great therapeutic potential. But the specific delivery of siRNAs to target cells to exert their effects remains a significant challenge. A novel nanoparticle-based approach that enables more efficient delivery of siRNA drugs is presented in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc. publishers The article is available on the Nucleic Acid Therapeutics website...
Decisions People Make After Being Diagnosed With Conditions Like Diabetes May Lead To Higher Health Risks
Date: Apr-15-2013It may seem counter-intuitive to take health advice from a marketing professor, but when it comes to analyzing consumer data and its relationship to managing health issues such as diabetes, one University of Alberta researcher may have the right prescription. In a paper recently published in the Journal of Marketing, Alberta School of Business professor Yu Ma uncovered information that has implications for health-care professionals, marketers and consumers alike...
