Randomized Controlled Trial
Impact of celecoxib on inflammation during cancer surgery: a randomized clinical trial.
During cancer surgery, prostaglandin-mediated inflammation may promote and activate micrometastatic disease with a consequent increase in long-term cancer recurrence. Cyclooxygenase-2 inhibitors, known to have anti-proliferative properties, may offset such perioperative perturbation. We investigated the effectiveness of these agents to minimize inflammatory changes during cancer surgery. ⋯ Standard dosing of the cyclooxygenase-2 inhibitor celecoxib slightly reduced perioperative cyclooxygenase activity during cancer surgery. Given cyclooxygenase's role in cancer pathways, we recommend dose-finding studies be undertaken before prospective clinical trials are conducted testing the currently unsubstantiated hypothesis that perioperative anti-inflammatory administration improves long-term cancer outcomes. This trial was registered at: Australian New Zealand Clinical Trial Registry: ACTRN12615000041550; www.anzctr.org.au.

To present a case of mycobacterium infection transmitted through a heater-cooler unit during cardiac bypass surgery. ⋯ Heater-cooler units manufactured by LivaNova prior to September 2014 and used during cardiopulmonary bypass have been linked to M. chimera, which causes a latent infection that may be activated and become disseminated in cases of immunosuppression related to steroid use.
