The Spectrum of Global Electron Content: A New Potential Indicator of Space Weather Activity.

The time evolution of the total number of free electrons in the Earth's ionosphere, i.e., the Global Electron Content (GEC), during more than two solar cycles is analyzed in this work. The GEC time series has been extracted from the Global Ionospheric Maps (GIMs) of Vertical Total Electron Content (VTEC) estimated by UPC-IonSAT with TOMION-v1 software from global GPS measurements since the end of 1996. A dual-layer voxel-based tomographic model solved with a forward Kalman scalar filter, from dual-frequency carrier GPS data only, provides the so-called UQRG GIM after VTEC kriging interpolation, with a resolution of 15 min in time, 5° in longitude and 2.5° in latitude. UQRG is one of the best behaving GIMs in the International GNSS Service (IGS).In this context, the potential application of the GEC spectrum evolution as a potential space weather index is discussed and demonstrated.

Drug Diversion in the Anesthesia Profession: How Can Anesthesia Patient Safety Foundation Help Everyone Be Safe? Report of a Meeting Sponsored by the Anesthesia Patient Safety Foundation.

Diversion in the workplace can adversely impact the safety of healthcare professionals and patients. The Anesthesia Patient Safety Foundation (APSF) believes that substance use disorder, diversion in the workplace, and their potential adverse effects on patient safety need to be addressed through open discussion, education, research, policy, and possible other interventions. To make progress in this area, the APSF convened a conference entitled "Drug Diversion in the Anesthesia Profession: How Can APSF Help Everyone Be Safe?" in Phoenix, Arizona, on September 7, 2017 (Supplemental Digital Content, Document, http://links.lww.com/AA/C616). It was comoderated by the authors.
