Little is known regarding the effects of caseload volume of other relevant members of the "surgical team." The present study sought to report variations in health care utilization and outcomes relative to surgeon and anesthesiologist volume among patients undergoing pancreatic surgery. ⋯ Although variability exists in health care practices among providers at the surgeon level, less is observed among anesthesiologists. Although a proportion of this variability can be explained by provider volumes, a significant proportion remains unexplained possibly due to nonmodifiable factors such as patient case mix.

Informed consent is important for limited English proficient (LEP) patients undergoing surgery, as many surgical procedures are complicated, making patient comprehension difficult even without language barriers. The study objectives were to (1) understand surgeons' preoperative consenting process with LEP patients, (2) examine how surgeons self assess their non-English language proficiency levels using a standardized scale, and (3) identify the relationship between self assessed non-English language proficiency and surgeons' self-reported use of interpreters during preoperative informed consent. ⋯ Surgeons reported relying on their own non-English language skills, bilingual staff, and family and friends of patients to obtain informed consent from LEP patients, suggesting that further understanding of barriers to professional interpreter use is needed.

CDP-choline (cytidine-5'-diphosphocholine) improves functional recovery, promotes nerve regeneration, and decreases perineural scarring in rat peripheral nerve injury. The aim of the present study was to investigate the mechanism of action of CDP-choline with regard to matrix metalloproteinase (MMP) activity in the rat-transected sciatic nerve injury model. ⋯ Our data show, for the first time, that CDP-choline modulates MMP activity and promotes the expression of TIMPs to stimulate axonal regeneration. These data help to explain one mechanism by which CDP-choline provides neuroprotection in peripheral nerve injury.

Comparative Study
Suture, synthetic, or biologic in contaminated ventral hernia repair.
Data are lacking to support the choice between suture, synthetic mesh, or biologic matrix in contaminated ventral hernia repair (VHR). We hypothesize that in contaminated VHR, suture repair is associated with the lowest rate of surgical site infection (SSI). ⋯ Interval estimates favored biologic matrix repair in contaminated VHR; however, these results were not statistically significant. In the absence of higher level evidence, surgeons should carefully balance risk, cost, and benefits in managing contaminated ventral hernia repair.

Multiple prior studies have suggested an association between survival and beta-blocker administration in patients with severe traumatic brain injury (TBI). However, it is unknown whether this benefit of beta-blockers is dependent on heart rate control. The aim of this study was to assess whether rate control affects survival in patients receiving metoprolol with severe TBI. Our hypothesis was that improved survival from beta-blockade would be associated with a reduction in heart rate. ⋯ Our study shows an association with improved survival in patients with severe TBI receiving metoprolol, and this effect appears to be independent of any reduction in heart rate. We suggest that beta-blockers should be administered to all severe TBI patients irregardless of any perceived beta-blockade effect on heart rate.
