Comparative Study
Poly-N-acetyl glucosamine fibers are synergistic with vacuum-assisted closure in augmenting the healing response of diabetic mice.
Vacuum-assisted closure (VAC) has become the preferred modality to treat many complex wounds but could be further improved by methods that minimize bleeding and facilitate wound epithelialization. Short fiber poly-N-acetyl glucosamine nanofibers (sNAG) are effective hemostatic agents that activate platelets and facilitate wound epithelialization. We hypothesized that sNAG used in combination with the VAC device could be synergistic in promoting wound healing while minimizing the risk of bleeding. ⋯ The application of sNAG fiber-containing membranes before the application of the polyurethane foam interface of VAC devices leads to superior healing in db/db mice and represents a promising wound healing adjunct that can also reduce the risk of bleeding complications.

Several studies evaluating simulation training in intensive care unit (ICU) physicians have demonstrated improvement in leadership and management skills. No study to date has evaluated whether such training is useful in established ICU advanced practitioners (APs). We hypothesized that human patient simulator-based training would improve surgical ICU APs' skills at managing medical crises. ⋯ Human patient simulator training in established surgical ICU APs improves leadership, teamwork, and self-confidence skills in managing medical emergencies. Such a validated curriculum may be useful as an AP continuing education resource.

During the initial development of an Emergency General Surgery (EGS) service, severity of illness (SOI) can be expected to be high and should decrease as the service matures. We hypothesize that a matured regional EGS service would show decreasing mortality and length of stay (LOS) over time. ⋯ Despite consistently high SOI, a dedicated and matured EGS service demonstrated a decrease in mortality and LOS.

Traumatic injury is a major global health problem, accounting for approximately 1 in 10 deaths worldwide. Hemorrhagic shock accounts for 30% to 40% of injury-associated deaths (2/3 of those patients surviving to reach the hospital) and is the leading cause of preventable and early in-hospital mortality. Excessive blood loss is an infrequent but important complication of both elective and emergency surgery, increasing the risk of morbidity and mortality and prolonging the duration of hospital stay. ⋯ The following case studies illustrate the effective use of the mRDH bandage in a variety of settings, as follows: (1) application of the mRDH to control severe hemorrhage from an improvised explosive device-induced lower extremity injury in Iraq and (2) the mRDH terminates bleeding from a penetrating groin wound allowing safe neurosurgical intervention while avoiding a groin exploration.

Neer IIB distal clavicle fracture is associated with disruption of the coracoclavicular ligament and a variable degree of displacement. Surgical treatment using various implants such as intramedullary wires, screws, and plates has been described in the literature with satisfactory results. ⋯ Minimally invasive surgery using titanium cable seems to be a good option for the treatment of Neer IIB distal clavicle fractures, with early functional recovery and no requirement for revision surgery.
