Observational Study
Differences of Recovery from Rocuronium-induced Deep Paralysis in Response to Small Doses of Sugammadex between Elderly and Nonelderly Patients.
WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Complete recovery from rocuronium-induced muscle paralysis with sugammadex is reported to be delayed in elderly patients. The authors tested a hypothesis that recovery from deep neuromuscular block with low-dose sugammadex is slower (primary hypothesis) and incidence of recurarization is higher (secondary hypothesis) in elderly patients than in nonelderly patients. ⋯ Elderly patients are at greater risk for recurarization and residual muscle paralysis when low-dose sugammadex is administered.

Observational Study
Impact of the Choice of Risk Model for Identifying Low-risk Patients Using the 2014 American College of Cardiology/American Heart Association Perioperative Guidelines.
WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: The 2014 American College of Cardiology Perioperative Guideline recommends risk stratifying patients scheduled to undergo noncardiac surgery using either: (1) the Revised Cardiac Index; (2) the American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator; or (3) the Myocardial Infarction or Cardiac Arrest calculator. The aim of this study is to determine how often these three risk-prediction tools agree on the classification of patients as low risk (less than 1%) of major adverse cardiac event. ⋯ There is wide variability in the predicted risk of cardiac complications using different risk-prediction tools. Including more than one prediction tool in clinical guidelines could lead to differences in decision-making for some patients depending on which risk calculator is used.

Randomized Controlled Trial Comparative Study
Effect of Equipotent Doses of Propofol versus Sevoflurane Anesthesia on Regulatory T Cells after Breast Cancer Surgery.
WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Clusters of differentiation 39 and 73, enzymes expressed on the surface of regulatory T cells, promote cancer recurrence and metastasis by suppressing immune cells. The authors hypothesized that propofol is less immunosuppressive than volatile anesthetics. The objective of this randomized trial was to compare the changes in cluster of differentiation 39 and 73 expression on regulatory T cells between propofol- and sevoflurane-based anesthesia during breast cancer surgery. ⋯ Changes in immune cells were similar with propofol and sevoflurane during breast cancer surgery. The effect of anesthetics on the perioperative immune activity may be minimal during cancer surgery.
