To explore the hypothesis that decreased arginine availability by myeloid-derived suppressor cells (MDSCs) is a cause of T-cell dysfunction after physical injury (PI). ⋯ Arginine availability is decreased after PI coinciding with an induction of MDSC expressing arginase 1. Decreased arginine may inhibit T-cell function and increase susceptibility to infection after injury.

Observational Study
Factors associated with adoption of robotic surgical technology in US hospitals and relationship to radical prostatectomy procedure volume.
Robotic technology has diffused rapidly despite high costs and limited additive reimbursement by major payers. We aimed to identify the factors associated with hospitals' decisions to adopt robotic technology and the consequences of these decisions. ⋯ Local area robot competition was associated with the rapid spread of robot technology in the United States. Significantly more radical prostatectomies were performed in hospitals with robots and in market areas of hospitals with robotic technology.

Review Meta Analysis
Preoperative smoking status and postoperative complications: a systematic review and meta-analysis.
To systematically review and summarize the evidence of an association between preoperative smoking status and postoperative complications elaborated on complication type. ⋯ Preoperative smoking was found to be associated with an increased risk of the following postoperative complications: general morbidity, wound complications, general infections, pulmonary complications, neurological complications, and admission to the intensive care unit.
