In response to Illinois Department of Public Health reports of rising rates of C. difficile infection as a hospital discharge diagnosis, the Chicago and Cook County health departments surveyed 25 Chicago-area hospitals over one month in 2009. They identified 263 total cases of C. difficile illness. Of 129 C. difficile isolates cultured from these patients, 61 percent were the outbreak C. difficile strain known as BI/NAP1.
The BI strain, which is known to cause more serious illness, is usually associated with large acute outbreaks of C. difficile. However this investigation suggests that BI is endemic in the Chicago area and patients could be at risk for severe disease even in the absence of a large acute outbreak.
"Our findings highlight the need for effective interventions aimed at reducing the risk of C. difficile infection," said Stephanie Black, MD with the Chicago Department of Public Health and the investigation's lead author.
The investigation suggests that the transfer of patients from one facility to another has helped to spread the BI strain. Dr. Black and her team found that half of the patients with the BI strain were transferred from one healthcare facility to another. "Inter-facility transfer of recently infected patients is a plausible mechanism for the spread of the BI group and may explain in part how BI became the dominant [strain] in this region," the authors write.
C. difficile is most common in elderly patients and those receiving treatment with antibiotics. It is considered to be one of the most important health care-related infections in the U.S.
The Society for Healthcare Epidemiology of America recommends that patients take the following steps to reduce the spread of C. difficile:
Make sure that all doctors, nurses, and other healthcare providers clean their hands with soap and water.
Only take antibiotics as prescribed by your doctor.
Be sure to clean your own hands often, especially after using the bathroom and before eating.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
