Elevating Infection Prevention: Critical Next Steps
June 21st 2011ICT spoke with Russell N. Olmsted, MPH, CIC, the 2011 president of the Association for Professionals in Infection Control and Epidemiology (APIC), about current issues and critical next steps to advance the infection prevention agenda.
Cooling System May Build Eggs' Natural Defenses Against Salmonella
June 21st 2011Once eggs are laid, their natural resistance to pathogens begins to wear down, but a Purdue University scientist believes he knows how to rearm those defenses. Kevin Keener, an associate professor of food science, created a process for rapidly cooling eggs that is designed to inhibit the growth of bacteria such as salmonella. The same cooling process would saturate the inside of an egg with carbon dioxide and alter pH levels, which he has found are connected to the activity of an enzyme called lysozyme, which defends egg whites from bacteria.
Addressing OR Challenges Through Smart Instrument Purchasing
June 21st 2011Hospital operating rooms (ORs) and ambulatory surgery centers (ASCs) must confront more than their fair share of challenges in the current healthcare environment. Many facilities are working with limited capital and non-capital budgets; facilities have cut back on spending. Volumes of surgical procedures have been reduced as a notable percentage of people are unexpectedly without insurance due to job losses. Those patients are procrastinating on surgical procedures while they search for new employment.
Study Discovers How Microbes Make It Past Tight Spaces Between Cells
June 17th 2011There are 10 microbial cells for every one human cell in the body, and microbiology dogma holds that there is a tight barrier protecting the inside of the body from outside invaders, in this case bacteria. Bacterial pathogens can break this barrier to cause infection and senior author Jeffrey Weiser, MD, professor of microbiology and pediatrics from the Perelman School of Medicine at the University of Pennsylvania, and first author Thomas Clarke, PhD, a postdoctoral fellow in the Weiser lab, wondered how microbes get inside the host and circulate in the first place. Weiser and Clarke tested to see if microbes somehow weaken host cell defenses to enter tissues.
How the Immune System Fights Back Against Anthrax Infections
June 16th 2011Scientists at the University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences have uncovered how the bodys immune system launches its survival response to the notorious and deadly bacterium anthrax. The findings, reported online today and published in the June 22 issue of the journal Immunity, describe key emergency signals the body sends out when challenged by a life-threatening infection.
