Artificial Intelligence Literacy: Developing a Multi-institutional Infrastructure for AI Education.

RATIONALE AND OBJECTIVES: To evaluate the effectiveness of an artificial intelligence (AI) in radiology literacy course on participants from nine radiology residency programs in the Southeast and Mid-Atlantic United States. MATERIALS AND METHODS: A week-long AI in radiology course was developed and included participants from nine radiology residency programs in the Southeast and Mid-Atlantic United States. Ten 30 minutes lectures utilizing a remote learning format covered basic AI terms and methods, clinical applications of AI in radiology by four different subspecialties, and special topics lectures on the economics of AI, ethics of AI, algorithm bias, and medicolegal implications of AI in medicine. A proctored hands-on clinical AI session allowed participants to directly use an FDA cleared AI-assisted viewer and reporting system for advanced cancer. Pre- and post-course electronic surveys were distributed to assess participants' knowledge of AI terminology and applications and interest in AI education. RESULTS: There were an average of 75 participants each day of the course (range: 50-120). Nearly all participants reported a lack of sufficient exposure to AI in their radiology training (96.7%, 90/93). Mean participant score on the pre-course AI knowledge evaluation was 8.3/15, with a statistically significant increase to 10.1/15 on the post-course evaluation (p= 0.04). A majority of participants reported an interest in continued AI in radiology education in the future (78.6%, 22/28). CONCLUSION: A multi-institutional AI in radiology literacy course successfully improved AI education of participants, with the majority of participants reporting a continued interest in AI in radiology education in the future.

Endogenous opiates modulate the postapnea ventilatory response in the obstructive sleep apnea syndrome.

Defense of ventilatory homeostasis against recurrent hypercapnia, hypoxia, and acidosis resulting from apnea in obstructive sleep apnea syndrome (OSAS) is dependent on compensatory mechanisms operative between episodes of airway obstruction. This investigation was designed to examine whether endogenous opiate activity modulates the compensatory ventilatory response to apnea in OSAS. Polysomnography and quantitative measurement of tidal volume was performed in 12 patients with moderate to severe OSAS during a morning nap study before and after intravenous administration of 10 mg of naloxone. Apnea index was not significantly altered. There was a small but significant shortening of apneas (postnaloxone apnea duration, 91.2% of prenaloxone; p = 0.002 by ANOVA). Tidal volume of the first postapnea breath and minute ventilation extrapolated from the first two postapnea breaths, but not frequency, increased significantly after naloxone (postnaloxone first breath volume, 112.7% of prenaloxone value [p = 0.03], with a similar increase for minute ventilation, 115.1% [p = 0.007]). The volume of the first postapnea breath was correlated with the duration of the previous apnea, both before (r = 0.59, p = 0.0001) and after naloxone. Despite this, analysis of covariance with apnea duration as the covariate confirmed a significant independent increase in postapnea breath volume after naloxone (p = 0.001). Naloxone also altered sleep architecture, increasing percent time awake during the study period (prenaloxone, 36.3 +/- 15.6%; postnaloxone, 56.7 +/- 22.4%; p = 0.0003) and decreasing total sleep time and percent time in Stage 1. Furthermore, naloxone increased continuity of awake periods (mean length of awake periods increased from 27.0 +/- 8.4 to 66.0 +/- 66.6 s after naloxone, p = 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
