Jagannadha Avasarala from Kansas Neurological Consultants, Wichita analysed treatment trends between 1998 and 2004 for all Federal Drug Administration (FDA) approved IMA drugs, together with colleagues from Wake Forest University School of Medicine, NC, and Ohio State University Medical Center. They used National Ambulatory Medical Care Survey (NAMCS) data to evaluate prescribing trends as well as type of physician and geographic location.
Avasarala found that an estimated 6.7million MS patient visits occurred during the study timescale: 3.4 visits per 1000 persons each year. Women were seen four times as often as men and Caucasians had a higher visit rate than African Americans (90% vs 8%). This may because MS is more prevalent amongst Caucasian women than any one ethnic group. Neurologists prescribed IMAs more often than family practitioners or internists, with urban patients visited neurologists than their rural counterparts. The NAMCS data showed that 62% of established MS patients evaluated by neurologists and 92% of those seeing family medicine practitioners or internists were not being treated with IMAs. The higher treatment rate among neurologists probably reflects greater awareness of these drugs and familiarity with MS cases.
“Strategies for educating both neurologists and non-neurologists about the benefits of initiating IMA use in MS patients and in continuing their use remain critical to improving long-term patient outcomes in treatment of MS” Says Avasarala.
MS is among the leading causes of disability in young adults, and accumulates over time. IMAs can reduce the frequency of new lesions, relapses and the rate of cerebral atrophy.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
