Researchers from Lund University and the University of Zurich have developed a way to use mass spectrometry to measure hundreds of proteins in a single blood sample. With the help of protein patterns it is then possible to determine the severity of a patient's sepsis and which organs have been damaged. The method is presented in an article in Nature Communications.

Antibiotics that fight infection can adversely affect the digestive tract and give destructive bacteria a chance to flourish, said assistant professor of veterinary and biomedical sciences Joy Scaria of South Dakota State University. His research seeks to identify probiotic mixes to treat intestinal infections, such as Clostridium difficile.

Since prehistoric times, clays have been used by people for medicinal purposes. Whether by eating it, soaking in a mud bath, or using it to stop bleeding from wounds, clay has long been part of keeping humans healthy. Certain clays have also been found with germ-killing abilities, but how these work has remained unclear. A new discovery by Arizona State University scientists shows exactly how two specific metallic elements in the right kinds of clay can kill troublesome bacteria that infect humans and animals.

Q: Recently our facility was cited for disinfected laryngoscope blades that were found unprotected from re-contamination in storage. What is the recommended practice for these items?A: This question has many implications. CDC’s Healthcare Infection Control Practices Advisory Committee (HICPAC) says laryngoscope blades are “semicritical” items, which are defined as, “Items that directly or indirectly contact mucous membranes of the respiratory tract. They should be sterilized or subjected to high-level disinfection before reuse.”  After they are cleaned according to the manufacturer’s IFU, there are several options for processing laryngoscope handles and blades. Many laryngoscope blades can be high-level-disinfected. If high-level disinfection is used (check the manufacturer’s IFU for compatible chemicals), the blade must be protected from recontamination after processing. One way of accomplishing this is to place the blade in a zip-lock bag and then apply a “Clean Not Sterile” label to the top of the bag. (Make sure that you clean your hands first.)  If anyone opens the bag, the label will be damaged indicating the blade could be contaminated. At some facilities, laryngoscope blades are sterilized, which is acceptable but not necessary (CDC, 2003). Packaging blades requires the package to be opened if nursing must test the laryngoscope bulb on the blade. This results in a blade being replaced inside an open paper-plastic pouch.  The opened pouch does not protect the blade from contaminates.
