Among the physical decontamination methods, treatment with ultraviolet (UV) radiation is a suitable means of preventing viral infections. Mercury vapor lamps (254 nm) used for room decontamination are potentially damaging to human skin (radiation) and harmful to the environment (mercury). Therefore, other UV-C wavelengths (100-280 nm) may be effective for virus inactivation on skin without damaging it, e.

An excess of reactive oxygen species (ROS), leading to oxidative stress, is a major factor in aging. Antioxidant therapies are considered crucial for delaying aging. Nanoceria, a nanozyme with antioxidant activity, holds significant potential in protecting cells from oxidative stress-induced damage.

Perioperative anaphylaxis is a serious entity with high morbidity and mortality. Perioperative anaphylaxis can be caused by any of the multitude of medications and substances used in anesthesia and surgery, and the most common causes include neuromuscular blocking agents, antibiotics, antiseptics, latex, and dyes. The differential diagnosis of perioperative anaphylaxis is wide from both an immunologic and a nonimmunologic standpoint.

In this study, we examined the effect of a bundled approach to blood collection for blood culture on decreasing contamination. Commensal organisms were considered contaminants on the basis of the clinical course if they were recovered from only a single blood draw (set) and if a positive result for two sets was not obtained within 72 hours. The main elements of the bundle were blood collection by venipuncture, skin preparation with a chlorhexidine alcohol swab, disinfection of culture bottles, and use of a sterile blood transfer device instead of the two-needle technique for inoculation.

Some preoperative skin antiseptics and contrast media that are used in a variety of specialties (eg, cardiovascular, urology) contain iodine. Clinicians and patients may believe that a history of a reaction to shellfish, povidone-iodine, or radiopaque contrast media is an allergy requiring avoidance of all three substances.
