Jockey safety is of paramount importance from the standpoint of welfare and public perception. Thus, an understanding of the epidemiology and associated risk factors is necessary to implement measures to reduce the jockey falls (JFs) and jokey injuries (JIs). This descriptive epidemiological study investigated the occurrence of JFs and JIs in 715,210 and 25,183 rides in flat and jump races, respectively, from 2003 to 2017. In flat races, the incidence rates of JFs and JIs were 1.4 and 0.6 per 1,000 rides, respectively. In jump races, they were 44.4 and 18.1 per 1,000 rides, respectively. In flat races, 56.8% of JFs at corners resulted in JIs. In jump races, the major causes of JFs and JIs were lost balance and hampered by a fallen horse at an obstacle. Our findings provide a basis to design a future study analyzing risk factors for JFs.

Objective: The aim of this study was to validate the usefulness of the measurement of lung insufflation capacity (LIC) using the LIC TRAINER (LT) in patients with amyotrophic lateral sclerosis (ALS). Methods: This retrospective study was conducted in the rehabilitation departments of the Japanese National Center of Neurology and Psychiatry and involved 20 ALS patients who underwent respiratory therapy between April 1, 2014, and December 2017. The vital capacity (VC), maximum insufflation capacity (MIC), and LIC measurements at the start of respiratory therapy were extracted from the medical records, and patients were divided into three groups: group A, VC could not be measured; group B, VC could be measured, but MIC was less than VC; and group C, MIC was larger than VC. LIC could be measured in all groups. In group C, paired t-tests were used to analyze whether there was a significant difference in the volumes measured using different methods. Results: LIC was 950, 1863±595, and 2980±1176 ml in groups A (n=1), B (n=10), and C (n=9), respectively. In groups A and B, LIC could be measured in all patients, even when VC or MIC could not be measured. In group C, the measured LIC value was significantly greater than MIC (p=0.003). Conclusion: LIC could be successfully measured using the LT. By using the LT, it was feasible to conveniently perform LIC measurements, suggesting that it could be a useful device for performing respiratory therapy in ALS patients.
