Randomized Controlled Trial
Talactoferrin alfa, a recombinant human lactoferrin promotes healing of diabetic neuropathic ulcers: a phase 1/2 clinical study.
Talactoferrin alfa, a recombinant form of human lactoferrin, is a novel immunomodulatory protein with demonstrated ulcer healing properties in animal models. ⋯ Topical talactoferrin appears to be safe and well tolerated and improves healing of diabetic neuropathic ulcers.

Randomized Controlled Trial
The use of cognitive task analysis to improve the learning of percutaneous tracheostomy placement.
The purpose of the current study was to determine the effectiveness of using cognitive task analysis (CTA) to develop a curriculum to teach the behavioral skills and the cognitive strategies of a percutaneous tracheostomy (PT) placement. ⋯ The use of CTA was effective in improving the cognitive processes and technical skills of performing a PT for surgical residents.

Randomized Controlled Trial Comparative Study
Ischemic preconditioning versus intermittent vascular occlusion in liver resections performed under selective vascular exclusion: a prospective randomized study.
The aim of this study was to compare ischemic preconditioning with the intermittent vascular occlusion technique in liver resections performed under inflow and outflow occlusion. ⋯ Although both techniques showed comparable efficacy for short ischemic times, intermittent vascular occlusion provided better cytoprotection when ischemia exceeded 40 minutes.

Usefulness of LigaSure for liver resection: analysis by randomized clinical trial.
The goal of the present study was to evaluate the efficacy of the novel LigaSure Vessel Sealing System (Valleylab, Boulder, CO) when used for liver resection. ⋯ The LigaSure system is an effective and safe tool for decreasing liver resection time.

Lecture versus standardized patient interaction in the surgical clerkship: a randomized prospective cross-over study.
Medical schools increasingly are incorporating the standardized patient (SP) interaction as a teaching and testing modality to prepare students for United States Medical Licensing Examination Step 2 Clinical Skills. Although SP interactions provide a safe environment in which to practice clinical skills, little is known about medical students' perceptions of the instructional SP interaction in comparison with the classic didactic lecture. We hypothesized that students would enjoy and value an instructional SP interaction more than a didactic lecture, and that this perception would be enhanced if the lecture immediately preceded the instructional SP interaction. ⋯ The classic lecture format not only is enjoyed and valued as a learning tool more by our surgical clerkship students than the instructional SP interaction, but having a lecture just before an SP interaction increased perceived enjoyment and value of the SP interaction and enhanced performance on the SP checklist. These data suggest that educators can improve student perceptions and attitudes surrounding the instructional SP interaction by using strategically timed lectures.
