It can help restore blood flow to the brain, but it also can increase the likelihood of deadly hemorrhage. In fact, many people experiencing a stroke do not receive tPA because the window for giving the drug is limited to the first few hours after a stroke's onset. http://medicalxpress.com/news/2013-05-tpa-clot-buster-brain-protector.html Neuroscience Tue, 07 May 2013 07:11:55 EST news287129505 The increasing proportion of the population that received treatment for a specific medical condition – called "treated disease prevalence"—along with higher spending per treated case accounted for most of the rise in health care spending in the U.S. between 1987 and 2009, according to a recent analysis. http://medicalxpress.com/news/2013-05-medical-treatment-greatest-health.html Health Mon, 06 May 2013 16:00:10 EST news287073417 The rise in childhood obesity and associated health conditions have become a significant concern in the United States. An initiative by the Alliance for a Healthier Generation, which fights childhood obesity, found benefits in expanding health care coverage to obesity services, preventive care and ensuring that families comply with preventive care guidelines. http://medicalxpress.com/news/2013-05-redesign-beneficial-children-obesity.html Health Fri, 03 May 2013 08:20:02 EST news286786971 Abuse during childhood is different. A study of adult civilians with PTSD (post-traumatic stress disorder) has shown that individuals with a history of childhood abuse have distinct, profound changes in gene activity patterns, compared to adults with PTSD but without a history of child abuse. http://medicalxpress.com/news/2013-05-ptsd-distinct-gene-patterns-childhood.html Psychology & Psychiatry Wed, 01 May 2013 16:02:40 EST news286642947 (Medical Xpress)—According to a recent study published in the New England Journal of Medicine, Americans with diabetes had increasingly better control of their blood sugar and cholesterol levels and attended more preventive check-ups from 1999 to 2010. However, one in five Americans with diabetes still smokes, blood pressure has not improved significantly, and approximately 40 percent don't receive education at diagnosis, annual vaccinations, or annual checks for diabetes complications. http://medicalxpress.com/news/2013-04-diabetes-potential-gaps.html Diabetes Thu, 25 Apr 2013 09:10:03 EST news286095966 If Don Stein were the kind of man who listened to what others said, he would have shut down his lab years ago. The Emory neuroscientist spent more than two decades investigating progesterone as a treatment for traumatic brain injury (TBI)—a pursuit that was unappreciated at best and maligned at worst. A naturally occurring hormone was too simple a solution to too complex a problem, according to the prevailing wisdom. http://medicalxpress.com/news/2013-04-hormone-brain-injury.html Medical research Wed, 24 Apr 2013 10:11:03 EST news286017053 The most common genetic cause of both ALS (amyotrophic lateral sclerosis) and FTD (frontotemporal dementia) was recently identified as an alteration in the gene C9orf72. But how the mutation causes neurodegenerative disease appeared mysterious. Researchers at Emory University School of Medicine have demonstrated that this ALS/FTD mutation may be harmful because it creates an "RNA sponge," soaking up an important regulatory protein that binds RNA. http://medicalxpress.com/news/2013-04-rna-sponge-mechanism-alsftd-neurodegeneration.html Genetics Mon, 01 Apr 2013 15:00:07 EST news284032530 (Medical Xpress)—Researchers have shown they can predict impending cognitive decline using a sensitive behavioral task up to three years in advance of clinical evidence. Until now, it has not been possible to reliably differentiate individuals at risk of mild cognitive impairment (MCI) and Alzheimer's disease (AD) from those who are not at risk. The results of this study are in the current (March 2013) issue of the American Journal of Alzheimer's Disease & Other Dementias. http://medicalxpress.com/news/2013-03-accurately-cognitive-decline.html Alzheimer's disease & dementia Wed, 27 Mar 2013 09:36:27 EST news283595735 In a study published in the April 2013 edition of Pediatrics, Emory researchers suggest that late preterm birth and maternal education have a relative impact on standardized test performance—the most common measure of academic performance and principal determinate of grade retention in public schools. http://medicalxpress.com/news/2013-03-prematurity-maternal-affect-early-academic.html Pediatrics Wed, 27 Mar 2013 07:20:01 EST news283586718 (Medical Xpress)—Emory Orthopaedics & Spine Center is now one of a small number of clinics in the country to offer a cutting edge stem cell treatment for Osteoarthritis (OA). http://medicalxpress.com/news/2013-03-stem-cell-relieve-arthritis-pain.html Arthritis & Rheumatism Wed, 20 Mar 2013 07:30:01 EST news282982741 (Medical Xpress)—The effects of antiepileptic drugs during pregnancy have long been a concern of clinicians and women of childbearing age whose seizures can only be controlled by medications. In 1999, a study called the Neurodevelopmental Effects of Antiepileptic Drugs (NEAD) began following the children of women who were taking a single antiepileptic agent during pregnancy. The drugs included carbamazepine, lamotrigine, phenytoin or valproate. http://medicalxpress.com/news/2013-03-fetal-exposure-antiepileptic-drug-valproate.html Neuroscience Wed, 20 Mar 2013 07:18:02 EST news282982655 Transfusion of donated blood more than three weeks old results in impaired blood vessel function, a new study of hospital patients shows. Blood banks now consider six weeks to be the maximum permitted storage time of blood for use in transfusion, but recent studies have suggested transfusing blood stored for more than a few weeks has adverse effects in patients undergoing cardiac surgery or critical care. http://medicalxpress.com/news/2013-03-donated-blood-weeks-nitric-oxide.html Medical research Sun, 10 Mar 2013 14:30:04 EST news282144569 (Medical Xpress)—A limited time window to administer therapy for ischemic stroke means every second counts.
