Surgical site infections (SSIs) are a common source of postoperative morbidity and a marker of surgical quality. The ability to predict the incidence of SSIs is limited and most models have poor predictive value. We sought to identify risk factors associated with SSIs and develop a prediction model for SSIs after major abdominal surgery. ⋯ A novel, simple 10-point SSI scoring system that incorporated perioperative risk factors such as blood transfusion, EBL, tachypnea, and the type of surgical procedure accurately stratifies patients according to SSI risk.

Tranexamic acid leads to paradoxical coagulation changes during cardiac surgery: a pilot rotational thromboelastometry study.
Tranexamic acid (TXA) is increasingly used during major surgery with the goal to reduce excessive bleeding, transfusion requirements, and reexploration. Our aim was to examine the effect of TXA on coagulation at different times during cardiac surgery using rotational thromboelastometry. ⋯ In this nonrandomized, nonblinded, observational trial, patients in the TXA group displayed prolonged CTs and clot fibrinogen (FIBTEM A5-30) after sternotomy, decreased clot strength (EXTEM) after CPB/surgery, and acute thrombocytopenia after protamine-sternal closure. There was no significant decrease in clot lysis, questioning the need for TXA in this medium-risk group.

Violent injury is the second most common cause of death among 15- to 24-year olds in the US. Up to 58% of violently injured youth return to the hospital with a second violent injury. Hospital-based violence intervention programs (HVIPs) have been shown to reduce injury recidivism through intensive case management. However, no validated guidelines for risk assessment strategies in the HVIP setting have been reported. We aimed to use qualitative methods to investigate the key components of risk assessments employed by HVIP case managers and to propose a risk assessment model based on this qualitative analysis. ⋯ We identified four tiers of risk factors for violent reinjury that were incorporated into a proposed risk assessment instrument, VRRAI.

Observational Study
Is enhanced recovery enough for reducing 30-d readmissions after surgery?
Few enhanced recovery pathways (ERPs) include processes related to the hospital to home transfer. Little has been reported regarding readmissions in enhanced recovery programs. This study evaluates readmissions and identifies areas to optimize ERPs to prevent readmissions. ⋯ Although ERPs did not reduce readmissions, the program was associated with reduced length of stay and surgical site infections. ERPs did not influence perceptions of the transition to home. Transition process measures aimed at reducing readmission and improving patient outcomes, including use of transition guides, remote vital sign and symptom monitoring, and early clinical follow-up have not traditionally been part of ERP protocols but should be considered.

Chronic nonhealing wound is a multifactorial complication of diabetes that results specifically as a consequence of impaired angiogenesis and currently lacks in effective treatments. Although a stem cell-based therapy may provide a novel treatment to augment diabetic wound healing, inferior cell survival at the diabetic skin wound is one of the key causes that are responsible for the low efficacy of the stem cell therapy. ⋯ The results indicated that the transplantation of allogeneic ADSCs via the hydrogel improves the efficiency of cell delivery and optimizes the performance of ADSCs for augmenting diabetic wound healing. In conclusion, this ADSC-based therapy may provide a novel therapeutic strategy for the treatment of nonhealing diabetic foot ulcers.
