(Press-News.org) CHICAGO (April 9, 2013)– In rooms of patients with multidrug-resistant organisms (MDROs), the outside of the packages containing sterile items can become contaminated. Unused medical supplies are often thrown away to prevent the items from becoming pathways for transmission of drug-resistant microbes, and in the process this leads to increased healthcare costs. Researchers at Johns Hopkins Hospital found that hydrogen peroxide vapor (HPV) is an effective way to sanitize the outside of the packages of these sterile supplies.
In addition to protecting patients, use of HPV could provide financial and environmental benefits. The study is published in the May issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America, in a special topic issue focused on the role of the environment in infection prevention.
In a two-phase study, Johns Hopkins Hospital researchers assessed the rate of contamination of packages containing sterile supplies and the ability of HPV to disinfect the outside of these packages. In each phase, five pairs of supplies from 20 rooms of patients colonized or infected with various MDROs were selected. One of each pair was sampled without exposure to HPV and the other was sampled after decontamination using HPV on a metal rack in patients' rooms.
In the initial study of packaged supplies taken from rooms of patients known to be colonized with vancomycin-resistant enterococci (VRE), 7% of 100 untreated packages were found to be contaminated with VRE, versus none of the 100 packaged supplies exposed to HPV. In the subsequent study that assessed all MDROs, one or more MDROs was grown from 9 of the 100 supply items not exposed to HPV and from none of the packages exposed to HPV.
Using inventory lists and electronic medical records, researchers projected the annual cost of discarded supplies because of potentially contaminated packages from patient isolation rooms from the six units included in the study to be $387,055. The researchers see this as a conservative estimate since medical waste disposal costs were not included.
"Our study results show that supplies in the rooms of patients in Isolation precautions can become contaminated with multidrug-resistant organisms, which may present a risk to other patients if they are not discarded or disinfected when the patient is discharged," said infectious disease specialist and study senior investigator Trish Perl, MD, MSc. "Hydrogen peroxide vapor looks to be a cost-effective and environmentally-friendly means to manage potentially contaminated packaged supplies."
Several study authors are employed by Bioquell, which provided HPV disinfection services without charge to Johns Hopkins Hospital for the duration of this study.

CHICAGO (April 9, 2013)– Placement of copper objects in intensive care unit (ICU) hospital rooms reduced the number of healthcare-acquired infections (HAIs) in patients by more than half, according to a new study published in the May issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America, in a special topic issue focused on the role of the environment in infection prevention.
In the United States, HAIs result in 100,000 deaths annually and add an estimated $45 billion to healthcare costs. HAIs often contaminate ...
Terrestrial species on low-lying islands and coastal regions are vulnerable to sea level rise due to climate-change, the most vulnerable species being endemics with limited ranges and rare species that are endangered already. That is the key message of a study by Florian Wetzel and colleagues of the Konrad Lorenz Institute of Ethology (KLIVV) of the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) and Walter Jetz of the Department of Ecology and Evolutionary Biology at Yale University, USA.
The new study is the first of its kind in terms of geographic scope ...

Patients with prostate cancer and hereditary mutations in the BRCA2 gene have a worse prognosis and lower survival rates than do the rest of the patients with the disease. This is the main conclusion to come out of a study published this week in the Journal of Clinical Oncology, in which David Olmos, Head of the Prostate Cancer and Genitourinary Tumours Clinical Research Unit at the Spanish National Cancer Research Centre (CNIO), has taken part in, along with Elena Castro, a member of the Unit, and British researchers at The Institute of Cancer Research and The Royal Marsden ...
Bremerhaven/Germany, 9 April 2013. Reliable information on the depth and floor structure of the Southern Ocean has so far been available for only few coastal regions of the Antarctic. An international team of scientists under the leadership of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, has for the first time succeeded in creating a digital map of the entire Antarctic seafloor. The International Bathymetric Chart of the Southern Ocean (IBCSO) for the first time shows the detailed topography of the seafloor for the entire area south of 60°S. ...
LEWISBURG, Pa. — Researchers have identified a new genus of bat after discovering a rare specimen in South Sudan. With wildlife personnel under the South Sudanese Ministry of Wildlife Conservation and Tourism, Bucknell Associate Professor of Biology DeeAnn Reeder and Fauna & Flora International (FFI) Programme Officer Adrian Garside were leading a team conducting field research and pursuing conservation efforts when Reeder spotted the animal in Bangangai Game Reserve.
"My attention was immediately drawn to the bat's strikingly beautiful and distinct pattern of spots and ...
University of Cincinnati research at the ancient Maya site of Medicinal Trail in northwestern Belize is revealing how populations in more remote areas – the hinterland societies – built reservoirs to conserve water and turned to nature to purify their water supply. Jeffrey Brewer, a doctoral student in the University of Cincinnati's Department of Geography, will present his findings on April 11, at the Association of American Geographers' annual meeting in Los Angeles.
Brewer's research, titled "Hinterland Hydrology: Mapping the Medicinal Trail Community, Northwest Belize," ...
The 'Mongolian Death Worm', called olgoi-khorkhoi by the local population is a legendary animal with an unconfirmed existence that has preoccupied the imagination of the inhabitants and travelers in the region. It is said to inhabit the southern Gobi Desert where it terrorizes travelers with its deadly abilities to project acid that, upon contact, turns anything it touches yellow and corroded.
Two new sub-species of earthworms, Eisenia nordenskioldi mongol and E. n. onon, are reported from the same region. Although neither of them possesses the fatal characteristics of ...

University of Cincinnati student Shujie Wang has discovered that a good way to monitor the environmental health of Antarctica is to go with the flow – the ice flow, that is.
It's an important parameter to track because as Antarctica's health goes, so goes the world's.
"The ice sheet in Antarctica is the largest fresh water reservoir on Earth, and if it were totally melted, the sea level would rise by more than 60 meters. So it is quite important to measure the ice mass loss there," says Wang, a doctoral student in geography in UC's McMicken College of Arts & Sciences.
