Postoperative cognitive dysfunction and delirium are undesirable consequences of surgery and anesthesia that regrettably do not have consistent predictive markers. Nor do they have reliable prophylactic or treatment methodologies. In an effort to better understand how anesthetic drugs alter the rate of postoperative delirium, Chang et al explore how patients with preoperative cognitive impairment respond to the influence of intraoperative ketamine. ⋯ Is it possible that ketamine and other drugs could be used as agents to stratify cognitive risk? Should we definitively avoid such drugs as potentiators of cognitive dysfunction? A variety of contextual limitations must be entertained when interpreting the results of this study as summarized in this infographic. These are also elaborated in greater detail in both the primary article as well as its attendant editorial. The reader is encouraged to review both in their entirety for an in-depth scope of understanding.

A Call to Action: A Specialty-Specific Course to Support the Next Generation of Clinician Scientists in Anesthesiology.
Clinical production pressure is a significant problem for faculty of anesthesiology departments who seek to remain involved in research. Lack of protected time to dedicate to research and insufficient external funding add to this long-standing issue. Recent trends in funding to the departments of anesthesiology and their academic output validate these concerns. ⋯ Directed toward early career academic anesthesiologists who wish to gain competency specifically in the fundamentals of clinical research and receive mentorship to develop an investigative project, the yearlong course will provide participants with the skills necessary to design research initiatives, ethically direct research teams, successfully communicate ideas with data analysts, and write and submit scientific articles. Additionally, the course, articulated in a series of interactive lectures, mentored activities, and workshops, will teach participants to review articles submitted for publication to medical journals and to critically appraise evidence in published research. It is our hope that this initiative will be of interest to junior faculty of academic anesthesiology departments nationally and internationally.

Reactive Oxygen Species Contributes to Type 2 Diabetic Neuropathic Pain via the Thioredoxin-Interacting Protein-NOD-Like Receptor Protein 3-N-Methyl-D-Aspartic Acid Receptor 2B Pathway.
The number of patients with diabetic neuropathic pain (DNP) continues to increase, but available treatments are limited. This study aimed to examine the influence of reactive oxygen species (ROS)-thioredoxin-interacting protein (TXNIP)-NOD-like receptor protein 3 (NLRP3)- N -methyl-D-aspartic acid receptor 2B (NR2B) pathway on type 2 DNP. ⋯ Our findings suggest that spinal ROS can contribute to type 2 DNP through TXNIP-NLRP3-NR2B pathway.

Randomized Controlled Trial Multicenter StudyA Multicenter, Randomized, Double-Blind, Placebo-Controlled Trial of Preoperative Antithrombin Supplementation in Patients at Risk for Antithrombin Deficiency After Cardiac Surgery.
Antithrombin (AT) activity is reduced during cardiac operations with cardiopulmonary bypass (CPB), which is associated with adverse outcomes. Preoperative AT supplementation, to achieve >58% and <100% AT activity, may potentially reduce postoperative morbidity and mortality in cardiac operations with CPB. This prospective, multicenter, randomized, double-blind, placebo-controlled study was designed to evaluate the safety and efficacy of preoperative treatment with AT supplementation in patients at risk for low AT activity after undergoing cardiac surgery with CPB. ⋯ AT supplementation did not attenuate adverse postoperative outcomes in our cohort of patients undergoing cardiac surgery with CPB.

Burnout Syndrome Among Anesthesia Providers Working in Public Hospitals in Rwanda: A Cross-Sectional Survey.
Many studies address anesthesia provider burnout in high-income countries; however, there is a paucity of data on burnout for anesthesia providers in low-income countries (LICs). Our objectives were (1) to evaluate the prevalence of burnout among anesthesia providers in Rwandan hospitals and (2) to determine factors associated with burnout among anesthesia providers in Rwandan hospitals. ⋯ In a cross-sectional survey of anesthesia providers in Rwanda, more than a quarter of respondents met the criteria for burnout. Lacking the right team and seeing negative outcomes were associated with higher burnout rate. These identified factors should be addressed to prevent the negative consequences of burnout, such as poor patient outcomes.
