Predicting major adverse cardiovascular events after orthotopic liver transplantation using a supervised machine learning model: A cohort study.

Background: Liver transplant (LT) patients have become older and sicker. The rate of post-LT major adverse cardiovascular events (MACE) has increased, and this in turn raises 30-d post-LT mortality. Noninvasive cardiac stress testing loses accuracy when applied to pre-LT cirrhotic patients.

The Author Impact Factor as a Metric to Evaluate the Impact of Neurosurgical Researchers.

Objective: The objective of this study was to assess the Author Impact Factor (AIF) as a useful metric and as a complement to the h-index among neurosurgical researchers.

Methods: The 5-year AIF and h-index were compared among 3 groups of researchers: 1) the 100 most prolific of all time within general neurosurgical journals ("Experienced"), 2) the 100 most prolific during the 2015-2019 period within general neurosurgical journals ("Trending Group"), and 3) the 100 postgraduation year 7 neurosurgical residents with the highest h-index ("Amateur").

Results: The Amateur group had a lower median h-index than the Experienced (6 vs.
