Background:
Violence-related injuries (VRIs) remain a major contributor to trauma-related mortality worldwide. We evaluated the case fatality rates (CFRs) of VRIs stratified by sex. We hypothesized that sex differences affect the CRF following VRIs.
Methods:
A retrospective analysis was conducted using data from the American College of Surgeons Trauma Quality Programs and ICD-10 for VRIs.
Results:
Among 522,939 VRIs patients, males accounted for 82.8% with higher mortality than females (7.5% vs. 5.6%). Males had higher CFRs than females among firearm-related injuries (16.3% vs. 15.2%), and Self-inflicted harm (SIH) (21.9% vs. 12.1%). In Interpersonal violence, CFRs among White females and Black males were 19.7% and 15.8%, respectively. For SIH, firearm lethality was higher among older White males ≥ 65 years (64.3%) and young Black males aged 36-45 (57.8%). Firearm injury (OR 18.49) and male sex (OR 1.21) were independent predictors for mortality.
Conclusion:
Sex-based disparities in VRIs in the United States are evident, notably in firearm injuries and SIH, underscoring the need for targeted injury prevention.

03:08Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
