Serum Troponin I Measurement of Subjects Exposed to the Taser X-26®

The Taser is a high-voltage, low-amperage conducted energy device used by many law enforcement agencies as a less lethal force weapon. The objective of this study was to evaluate for a rise in serum troponin I level after deployment of the Taser on law enforcement training volunteers. A prospective, observational cohort study was performed evaluating serum troponin I levels in human subjects 6 h after an exposure to the Taser X-26. Outcome measures included abnormal elevation in serum troponin I level (> 0.2 ng/mL). There were 66 subjects evaluated. The mean shock duration was 4.36 s (range 1.2-5 s). None of the subjects had a positive troponin I level 6 h after exposure. It was concluded that human volunteers exposed to a single shock from the Taser did not develop an abnormal serum troponin I level 6 h after shock, suggesting that there was no myocardial necrosis or infarction.

A Positive Domestic Violence Screen Predicts Future Domestic Violence

The objective of this study was to determine if a brief screen for domestic violence (DV) predicts future violence. We conducted a cohort study of adult women who presented to an inner-city emergency department during an 8-week study period. Participants were screened for DV using the Partner Violence Screen (PVS). At 4 months, follow-up telephone interviews were conducted: rates of verbal and physical violence were measured using the modified Conflict Tactics Scale. Relative risks of violent events (physical and verbal) were calculated.Of the 215 women who enrolled,36 (16%) had an initial screen positive for DV. Ninety-six women participated in the follow-up phase; of these women, 9% had screened positive for DV. At 4 months, women with DV were 11.3 times more likely to experience physical violence and 7.3 times more likely to experience verbal aggression. The study’s screen identified women at high risk for subsequent physical violence and verbal aggression.
