Disease Surveillance And Notification Systems Assessment After A Pandemic
Date: Apr-05-2013Significant investments over the past decade into disease surveillance and notification systems appear to have "paid off" and the systems "work remarkably well," says a Georgetown University Medical Center researcher who examined the public health response systems during the 2009 H1N1 influenza pandemic. The findings are published online today in PLOS ONE. After the Sept. 11 terrorist attacks in the U.S. and the potential threat of bioterrorism, many new advanced systems for disease surveillance and notification have been developed and implemented throughout the world...
The Economic Burden Of Dementia
Date: Apr-05-2013The monetary cost of dementia in the United States ranges from $157 billion to $215 billion annually, making the disease more costly to the nation than either heart disease or cancer, according to a new RAND Corporation study. The greatest economic cost of dementia is associated with providing institutional and home-based long-term care rather than medical services, according to the findings published in the New England Journal of Medicine. The study, funded by the National Institute on Aging, is the most-detailed examination done in recent decades on the costs of dementia...
New System Improving Understanding Of The Fundamental Genetic Principles Of Metastasis
Date: Apr-05-2013A new system for isolating rare circulating tumor cells (CTCs) - living solid tumor cells found at low levels in the bloodstream - shows significant improvement over previously developed devices and does not require prior identification of tumor-specific target molecules. Developed at the Massachusetts General Hospital (MGH) Center for Engineering in Medicine and the MGH Cancer Center, the device rapidly delivers a population of unlabeled tumor cells that can be analyzed with both standard clinical diagnostic cytopathology and advanced genetic and molecular technology...
The Importance Of Early Diagnosis And Treatment Of Age-Related Macular Degeneration
Date: Apr-05-2013Age-related macular degeneration (AMD) continues to be the leading cause of visual impairment in the United States for people over age 65, according to a study recently published online in Ophthalmology, the journal of the American Academy of Ophthalmology. AMD is a potentially blinding disease that affects more than 9.1 million Americans...
Walking Reduces Heart Risk As Much As Running
Date: Apr-05-2013Brisk walking can reduce a person's risk of diabetes, high blood pressure, and high cholesterol just as much as running can. The finding came from a new study published in the journal Arteriosclerosis, Thrombosis and Vascular Biology which examined 33,060 runners in the National Runners' Health Study and 15,045 walkers in the National Walkers' Health Study...
Women Are Choosing Cohabitation Before Marriage
Date: Apr-05-2013More couples are choosing to live together before they are married, suggests new research from the Centers for Disease Control and Prevention. Not only are couples living together longer before marriage, many become pregnant before marriage. Close to half of heterosexual women (48%) between 2006 and 2010, ranging in age from 15 to 44 years, reported they were not married to their partner or spouse when they first began cohabitation. This number has risen since the last report in 2002, which documented 43%, and up from 34% in 1995...
Researchers A Step Closer To Making HIV Vaccine
Date: Apr-05-2013Researchers have charted a new route that could help develop a vaccine to boost a person's ability to neutralize the HIV virus, according to a recent study published in the journal Nature. Barton F. Haynes, M.D., director of the Duke Human Vaccine Institute, and John Mascola, M.D., acting director of the NIH Vaccine Research Center, led a team of researchers who studied an HIV infected person whose immune system attacked the pathogen, allowing them to describe the co-evolution of antibodies...
Cleaning Up Waste Water From Slaughterhouses With Papyrus
Date: Apr-05-2013Humans have used the papyrus sedge for millennia. The Ancient Egyptians wrote on it, it can be made into highly buoyant boats, it is grown for ornamentation and parts can even be eaten. Now, writing in the International Journal of Environmental Technology and Management, researchers in Uganda have demonstrated that growing papyrus can be used to soak up toxins and other noxious residues from abattoir effluent...
The Flexibility Of Human Language - By Mouth And By Hand
Date: Apr-05-2013Humans favor speech as the primary means of linguistic communication. Spoken languages are so common many think language and speech are one and the same. But the prevalence of sign languages suggests otherwise. Not only can Deaf communities generate language using manual gestures, but their languages share some of their design and neural mechanisms with spoken languages. New research by Northeastern University's Prof. Iris Berent further underscores the flexibility of human language and its robustness across both spoken and signed channels of communication...
Effective HIV Vaccine On The Horizon
Date: Apr-05-2013By tracking the very earliest days of one person's robust immune response to HIV, researchers have charted a new route for developing a long-sought vaccine that could boost the body's ability to neutralize the virus. The research team, led by Barton F. Haynes, M.D., director of the Duke Human Vaccine Institute, and John Mascola, M.D., acting director of the NIH Vaccine Research Center, have for the first time described the co-evolution of antibodies and virus in a person with HIV whose immune system mounted a broad attack against the pathogen. Findings are published in the journal Nature...
