Hypoxia and immunity are highly intertwined at clinical, cellular, and molecular levels. The prevention of tissue hypoxia and modulation of systemic inflammation are cornerstones of daily practice in the intensive care unit. ⋯ On the other hand, hypoxia also exerts antiinflammatory and tissue-protective effects in lymphocytes and other tissues. Although human data on the net immunologic effects of hypoxia and pharmacologic modulation of downstream pathways are limited, preclinical data support the concept of tailoring the immune response through modulation of the oxygen status or pharmacologic modulation of hypoxia-signaling pathways in critically ill patients.

Observational Study
Minimal Clinically Important Difference for Three Quality of Recovery Scales.
Several quality of recovery (QoR) health status scales have been developed to quantify the patient's experience after anesthesia and surgery, but to date, it is unclear what constitutes the minimal clinically important difference (MCID). That is, what minimal change in score would indicate a meaningful change in a patient's health status? ⋯ Perioperative interventions that result in a change of 0.9 for the QoR score, 8.0 for the QoR-15, or 6.3 for the QoR-40 signify a clinically important improvement or deterioration.

Dementia after Cardiac Surgery: Is It the Procedure or the Patient?

Animals exposed to sevoflurane during development sustain neuronal cell death in their developing brains. In vivo micro-positron emission tomography (PET)/computed tomography imaging has been utilized as a minimally invasive method to detect anesthetic-induced neuronal adverse effects in animal studies. ⋯ Sevoflurane-induced general anesthesia during development increases glial activation, which may serve as a surrogate for neurotoxicity in the nonhuman primate brain. ALC is a potential protective agent against some of the adverse effects associated with such exposures.

Historical Article
No Silver Medal for Nobel Prize Contenders: Why Anesthesia Pioneers Were Nominated for but Denied the Award.
Taking the examples of the pioneers Carl Ludwig Schleich, Carl Koller, and Heinrich Braun, this article provides a first exploratory account of the history of anesthesiology and the Nobel Prize for physiology or medicine. Besides the files collected at the Nobel Archive in Sweden, which are presented here for the first time, this article is based on medical literature of the early 20th century. Using Nobel Prize nominations and Nobel committee reports as points of departure, the authors discuss why no anesthesia pioneer has received this coveted trophy. These documents offer a new perspective to explore and to better understand aspects of the history of anesthesiology in the first half of the 20th century.
