Researchers Identify Sleep Mechanism That Plays A Role In Emotional Memory
Date: Jun-17-2013Sleep researchers from University of California campuses in Riverside and San Diego have identified the sleep mechanism that enables the brain to consolidate emotional memory and found that a popular prescription sleep aid heightens the recollection of and response to negative memories. Their findings have implications for individuals suffering from insomnia related to posttraumatic stress disorder (PTSD) and other anxiety disorders who are prescribed zolpidem (Ambien) to help them sleep...
No Respite From The Heat For Farmworkers Even When They Leave The Fields
Date: Jun-17-2013Hot weather may be the work environment for the 1.4 million farmworkers in the United States who harvest crops, but new research shows that these workers continue to experience excessive heat and humidity even after leaving the fields. Wake Forest Baptist Medical Center researchers conducted a study to evaluate the heat indexes in migrant farmworker housing and found that a majority of the workers don't get a break from the heat when they're off the clock. Lead author Sara A. Quandt, Ph.D...
Don't Hit The Road Without A Helmet
Date: Jun-17-2013A laboratory study has found that bicycle helmets certified to Australia's national standard significantly reduce the causes of head, skull and brain injury - linear and angular head accelerations, and the impact force of a crash. Crashing without a helmet exposes the head to accelerations and forces - or loads - up to 9.5 times greater than with a helmet and so greatly increases the risk of head, skull and brain injury, according to a detailed biomechanical study published in the journal Traffic Injury Prevention...
New Technology Allows Fast, Reliable Pathogen Identification
Date: Jun-17-2013Life-threatening bacterial infections cause tens of thousands of deaths every year in North America. Increasingly, many infections are resistant to first-line antibiotics. Unfortunately, current methods of culturing bacteria in the lab can take days to report the specific source of the infection, and even longer to pinpoint the right antibiotic that will clear the infection. There remains an urgent, unmet need for technologies that can allow bacterial infections to be rapidly and specifically diagnosed...
Risk Of ACPA-Negative Rheumatoid Arthritis Increased By Childbirth
Date: Jun-17-2013Epidemiological data presented at EULAR 2013, the Annual Congress of the European League Against Rheumatism, demonstrate that pregnancy carried to childbirth (parity) increases the risk of ACPA-negative* rheumatoid arthritis (RA). The increased risk was demonstrated in women aged 18-44 who have had a child (2.1, 95% CI 1.4-3.2), but not in older women, and was more pronounced among those women with delivery during the first year of symptoms. RA is an autoimmune disease characterised by inflammation of the joints and tendons...
In Children With SJIA, Canakinumab Allows Discontinuation Of Corticosteroids
Date: Jun-17-2013Study findings first presented at EULAR 2013, the Annual Congress of the European League Against Rheumatism, demonstrate the efficacy of canakinumab at tapering corticosteroid (CS) use in patients with SJIA. Successful CS tapering was achieved within 20 weeks in almost half of patients (44.5%, p JIA is a chronic arthritis occurring in 1 in every 1,000 children; SJIA is a subset occurring in 10%-20% of cases, involving the body as a whole and impacting small joints such as hands, wrists, knees and ankles...
News From Frontiers In Microbiology, Oncology, Neuroscience
Date: Jun-17-2013Frontiers in Microbiology Insights into fungal communities in composts revealed by 454-pyrosequencing: Implications for human health and safety Composting is a process for converting waste into materials beneficial for plant growth through the action of microbes, especially of fungi which can break down large molecules. But fungi involved in composting are not always harmless. Vidya De Gannes and colleagues show that composts can contain more fungi that are potentially harmful to humans than was previously realized...
New Research Suggests Hands-Free Talking And Texting Are Unsafe
Date: Jun-17-2013Using hands-free devices to talk, text or send e-mail while driving is distracting and risky, contrary to what many people believe, says a new University of Utah study issued by the AAA Foundation for Traffic Safety. "Our research shows that hands-free is not risk-free," says University of Utah psychology Professor David Strayer, lead author of the study, which he conducted for the foundation arm of the nonprofit AAA, formerly known as the American Automobile Association...
Brain's 'Dark Side' May Be Key To Cocaine Addiction
Date: Jun-17-2013Scientists at The Scripps Research Institute (TSRI) have found evidence that an emotion-related brain region called the central amygdala - whose activity promotes feelings of malaise and unhappiness - plays a major role in sustaining cocaine addiction. In experiments with rats, the TSRI researchers found signs that cocaine-induced changes in this brain system contribute to anxiety-like behavior and other unpleasant symptoms of drug withdrawal - symptoms that typically drive an addict to keep using...
Greater Potential Benefit In Overall Survival For Eribulin Compared With Capecitabine For Metastatic Breast Cancer
Date: Jun-17-2013Subgroup analyses from a phase III clinical trial comparing a newer chemotherapy agent called eribulin mesylate, with capecitabine, a standard chemotherapy medication in women with previously treated metastatic breast cancer, showed increased benefit among women sharing certain traits. Specifically, these analyses demonstrated a greater potential benefit in certain subsets of patients with metastatic breast cancer. This analysis was presented by Peter A. Kaufman, M.D., during the 2013 ASCO Annual Meeting...
