In a study to be published in the February 1, 2011, issue of Clinical Infectious Diseases, researchers associated extreme obesity with a nearly three-fold increased odds of death from 2009 H1N1 influenza. Half of Californians greater than 20 years of age hospitalized with 2009 H1N1 were obese. (Please see below for a link to the study online.)
Data from 500 adults hospitalized with H1N1 in the first four months of 2009 in California were analyzed to test the hypothesis of obesity as a risk factor for increased fatality. Extreme obesity is defined as having a body mass index (BMI) equal to or over 40. The data was collected April 20 – Aug. 11, 2009, by health providers and reported to local health departments, which subsequently provided the data to the California Department of Public Health. During this period, H1N1 accounted for 50 percent of influenza-like illnesses. Patients under 20 years of age and pregnant patients were excluded from the study.
"Extremely obese persons with a body mass index equal to or over 40 should get vaccinated annually for influenza," according to study author Janice K. Louie, MD, MPH, of the California Department of Public Health. "They should also see their health provider early if symptoms of influenza develop, so that they can get diagnosed and treated as quickly as possible. This is especially important if the influenza virus is known to be circulating in the community and causing illness." Dr. Louie stressed that more research is needed to understand why extremely obese people are more likely to die from the 2009 H1N1 influenza infection.

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...
