RESUMEN
This study aims to identify the epidemiology and effects of facial fractures on return to play (RTP) in Major League Soccer (MLS) and the English Premier League (EPL). A total of 39 MLS players and 40 EPL players who sustained facial fractures from 2007 to 2019 were identified. Data on player demographics, the injury, and the impact of their injury on RTP were collected. Elbow-to-head was the most common mechanism of injury (20.3%). The most common fracture involved the nasal bone (48.3%). Most players (90%) RTP the same season. Players who sustained nasal fractures missed significantly fewer games (p < 0.001) than those who suffered other craniofacial fractures. Players treated surgically missed significantly more games (3.21 vs. 0.71, p = 0.006) and days (30.1 vs. 8.70, p = 0.002) than those managed nonoperatively. Significantly more EPL players who sustained facial fractures wore headgear upon RTP compared to MLS players (82% vs. 56%, p <0 .01). Most professional soccer players who sustain a facial fracture RTP the same season, but their recovery time can vary depending on the type of fracture, injury management, or injury severity. Our findings can help inform future craniofacial injury management as well as guidelines on player safety and fracture prevention.

The biological activity of natural products YM-254890 (YM) and FR900359 (FR) has led to significant interest in both their synthesis and the construction of more simplified analogs. While the simplified analogs lose much of the potency of the natural products, they are of interest in their own right, and their synthesis has revealed synthetic barriers to the family of molecules that need to be addressed if a scalable synthesis of YM and FR analogs is to be constructed. In the work described here, a synthetic route to simplified analogs of YM is examined and strategies for circumventing some of the challenges inherent to constructing the molecules are forwarded.
