Why Cats Lack A Sweet Tooth: New American Chemical Society Video
Date: Mar-06-2013Do cats purrr-ferrr sardines or sweets? The American Chemical Society (ACS), the world's largest scientific society, has released a new Bytesize Science video that explains why cats, unlike humans and other mammals, are indifferent to sweet flavors. The video was filmed at the Monell Chemical Senses Center, an institute dedicated to research on taste and smell. Prior to becoming Monell's Director, Gary Beauchamp, Ph.D., studied the sweet taste receptor genes of cats in the late 1970s...
Maternal Diet Important Predictor Of Severity For Infant RSV
Date: Mar-06-2013An important predictor of the severity of respiratory syncytial virus (RSV) in infants may be what their mothers ate during pregnancy, according to a Vanderbilt study published in the American Journal of Respiratory and Critical Care Medicine. RSV is the most common cause of severe lower respiratory tract disease among infants and young children worldwide. Currently there is no effective vaccine against RSV. Outbreaks occur in communities each year, usually lasting 4-5 months during the fall, winter and/or spring months. Lead author Fernando Polack, M.D...
Despite Improvement, Distribution Of Free Samples To Patients And Office Calls To Physicians Still Major Part Of Pharmaceutical Advertising
Date: Mar-06-2013The pharmaceutical industry has pulled back on marketing to physicians and consumers, yet some enduring patterns persist. According to a new study led by researchers at the Johns Hopkins Bloomberg School of Public Health, advertising peaked in 2004, with industry promotion to physicians declining nearly 25 percent by 2010, to $27.7 billion or 9 percent of sales. Similar declines were seen in direct-to-consumer advertising, which remains concentrated among a small number of products...
Patients Benefit From Quality Of Care Measures
Date: Mar-06-2013Public reporting of how physicians and hospitals perform in quality of care measures leads to improved care for patients. A collaborative team of researchers led by Geoffrey C. Lamb, M.D., professor of internal medicine at the Medical College of Wisconsin, published their findings in the March 2013 edition of Health Affairs...
Advancing Knowledge Of HIV Impact On Hepatitis C Infection And Genes That May Thwart HCV
Date: Mar-06-2013Infectious disease experts at Johns Hopkins have found that among people infected with the hepatitis C virus (HCV), co-infection with HIV, speeds damage and scarring of liver tissue by almost a decade. In a second study of HCV infection, the Johns Hopkins research team participated in the discovery of two genetic mutations that make it more likely that patients' immune systems can rid the body of HCV. Both studies are described in articles published online in February ahead of print in the journal Annals of Internal Medicine...
Study By Kennedy Krieger's Center For Autism And Related Disorders Reveals Key Predictors Of Speech Gains
Date: Mar-06-2013New findings published in Pediatrics (Epub ahead of print) by the Kennedy Krieger Institute's Center for Autism and Related Disorders reveal that 70 percent of children with autism spectrum disorders (ASD) who have a history of severe language delay, achieved phrase or fluent speech by age eight. This suggests that more children presenting with ASD and severe language delay at age four can be expected to make notable language gains than was previously thought...
Global Burden Of Disease And Injury Attributable To Alcohol Is Large And Growing
Date: Mar-06-2013A new study by the Centre for Addiction and Mental Health (CAMH) shows that alcohol is now the third leading cause of the global burden of disease and injury, despite the fact most adults worldwide abstain from drinking. This research, part of the 2010 Global Burden of Disease study, was published in this month's issue of the journal Addiction. It also found that Canadians drink more than 50 per cent above the global average. "Alcohol consumption has been found to cause more than 200 different diseases and injuries," said Kevin Shield, the lead author of the study...
Tracking Human Brain Activity Shows How The Brain Loses And Regains Consciousness
Date: Mar-06-2013Since the mid-1800s, doctors have used drugs to induce general anesthesia in patients undergoing surgery. Despite their widespread use, little is known about how these drugs create such a profound loss of consciousness. In a new study that tracked brain activity in human volunteers over a two-hour period as they lost and regained consciousness, researchers from MIT and Massachusetts General Hospital (MGH) have identified distinctive brain patterns associated with different stages of general anesthesia...
Viral Reservoirs In HIV-Infected Teens Reduced By Early Antiretroviral Treatment
Date: Mar-06-2013A study led by University of Massachusetts Medical School professor and immunologist Katherine Luzuriaga, MD, and Johns Hopkins Children's Center virologist Deborah Persaud, MD, highlights the long-term benefits of early antiretroviral therapy (ART) initiated in infants...
Better Tools Required To Evaluate Newborn Intensive Care Units And Improve Care For Vulnerable Infants
Date: Mar-06-2013Scoring methods commonly used to evaluate Newborn Intensive Care Units (NICU) are inconsistent, according to new research from the University of Michigan. The research published last week in the journal Pediatrics compared 10 well-known scores that have been developed to evaluate NICUs. The researchers found more differences than similarities...
