Most Sick, Aging Americans Live Far From In-Home Care

Posted 9 Aug 2016 by Drugs.com

TUESDAY, Aug. 9, 2016 – Most older Americans struggling with chronic illnesses live too far from "in-home" medical care providers to get the help they need to stay in their homes, a new study finds. At least 2 million Medicare beneficiaries are homebound, compared to fewer than 2 million beneficiaries who receive care in nursing homes, the researchers said. Yet, seven times more primary-care providers visited nursing homes than patients at home during the two-year study period. And more than half of Americans live more than 30 miles from a high-volume provider of "home-based medical care," the study also revealed. These services are mostly concentrated in large urban areas. Home-based medical care is a modern twist on the old-fashioned doctor's house call. It involves a team-based approach to managing the care of functionally limited, chronically ill older adults, the researchers ... Read more

MRI Technique May Help Detect Parkinson's Earlier

Posted 12 Jun 2014 by Drugs.com

THURSDAY, June 12, 2014 – A simple and quick MRI technique might aid in early detection of Parkinson's disease, British researchers report. The new MRI approach can detect with 85 percent accuracy people who have early stage Parkinson's disease, according to findings published online June 11 in the journal Neurology. That's important because the early symptoms of Parkinson's are subtle, which makes an accurate early stage diagnosis very difficult, the researchers said. This new test, which focuses on scans of a part of the brain known as the basal ganglia, could improve the lives of countless patients with Parkinson's, said senior author Clare Mackay, a senior research fellow with the Oxford Parkinson's Disease Center at Oxford University. "By the time symptoms of Parkinson's are obvious, a lot of damage has already taken place in the brain," Mackay said. "To reduce the impact of ... Read more

FDA Approves Dotarem, a New Magnetic Resonance Imaging Agent

Posted 25 Mar 2013 by Drugs.com

March 20, 2013 – The U.S. Food and Drug Administration today approved Dotarem (gadoterate meglumine) for use in magnetic resonance imaging (MRI) of the brain, spine and associated tissues of patients ages 2 years and older. Dotarem is a gadolinium-based contrast agent (GBCA) that helps radiologists see abnormalities on images of the central nervous system (CNS), the part of the body that contains the brain and spine, and surrounding tissues. “Dotarem was shown to be a safe and effective magnetic resonance imaging agent in patients ages 2 years and older,” said Dwaine Rieves, M.D., director of the Division of Medical Imaging Products in the FDA’s Center for Drug Evaluation and Research. “Today’s approval provides doctors with another option to help evaluate anatomic abnormalities within the central nervous system.” Dotarem’s safety and effectiveness were established in a clinical tria ...

Frequent MRI Scanner Exposure Might Affect Memory: Study

Posted 30 Aug 2012 by Drugs.com

THURSDAY, Aug. 30 – Exposure to magnetic fields generated by MRI scanners may lower a person's mental skills, according to a small new study. The effects were most noticeable in tasks that required high levels of working memory, which could have implications for surgeons and other medical staff who work within the vicinity of MRI scanners, the researchers said. The study was published online Aug. 29 in the journal Occupational and Environmental Medicine. Along with radio waves, MRI uses strong magnetic fields to obtain detailed images of the brain and spine, explains a journal news release. Three types of magnetic fields – static, switched gradient and radiofrequency – are used to create an MRI image. Even when no imaging is taking place, the static magnetic field is always present. Thirty volunteers completed the study. All were exposed to an MRI static magnetic field of zero, 0.5 ... Read more
