Despite a lack of evidence supporting their use, silver dressings are often used with negative pressure wound therapy (NPWT). This study investigates the effectiveness of silver dressings to reduce bacteria in contaminated wounds when used with NPWT. ⋯ The use of silver dressings with NPWT is a fairly common practice with limited literature to support its use in contaminated wounds. This study demonstrates that the addition of a silver dressing to NPWT effectively reduces bacteria in contaminated wounds and is more beneficial on the gram-positive bacteria. These data support the use of silver dressings in contaminated wounds, particularly ones contaminated by S. aureus.

Comparative Study
Immediate splenectomy decreases mortality and improves cognitive function of rats after severe traumatic brain injury.
Traumatic brain injury (TBI) is a major health problem all over the world. It frequently causes a considerable social burden because of its high incidence of death and long-term disability, especially in the case of severe TBI. Recent studies revealed that the spleen might contribute to secondary brain injury after ischemia or intracerebral hemorrhage. The purpose of this study was to evaluate the significance of the spleen in traumatic brain edema after severe TBI. ⋯ Our study demonstrates that splenectomy has a protective effect on rats with severe TBI by inhibiting proinflammatory cytokines, including IL-1β, TNF-α, and IL-6, both systematically and locally in the injured brain, hence leading to a decreased mortality and improved cognitive function.
