A new study adds potentially fatal blood infections to the list of health risks from diabetes, a condition that is on the rise in the United States as obesity rates climb, according to the Feb. 15 issue of Clinical Infectious Diseases, now available online.
Researchers have known for years that obesity and diabetes are linked. Most diabetics have type 2 diabetes--and most people with type 2 diabetes are obese. Diabetes can cause a host of health troubles, including kidney problems, damage to nerves and blood vessels and blindness. A heightened risk of infections in diabetic people has also been suggested. The condition known as sepsis can be brought on by bloodstream infection, and may lead to fever and septic shock, a potentially fatal drop in blood pressure.
Diabetic people are more vulnerable to bacterial blood infections called bacteremia, particularly if they develop other bacterial infections, such as urinary tract infections (UTIs). Danish researchers studied more than 1,300 patients with bacteremia caused by E. coli and related bacteria and found that about 17 percent had diabetes, compared with only 6 percent among the controls, who were matched for age and sex from the general population. Compared with non-diabetics, diabetic patients were more likely to have bacteremia caused by urinary tract infection, rather than abdominal infection. Death after bacteremia also occurred more often in diabetics than in non-diabetics.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
