PURPOSE: To evaluate the effects of 2 noise reduction techniques on the auditory brainstem response (ABR). METHOD: ABRs of 20 normal hearing adults were recorded during quiet and active behavioral conditions using 2 stimulus intensity levels. Wave V amplitudes and residual noise root-mean-square values were measured following the offline application of artifact rejection and Bayesian weighting. Repeated measures analysis of variance and Bonferroni adjusted pairwise t tests were utilized to evaluate significant main effects and interactions between the 2 noise reduction techniques. RESULTS: ABRs recorded during the quiet behavioral condition resulted in minimal differences in wave V amplitude and noise reduction improvement, suggesting that the 2 techniques were equally effective under ideal recording situations. During the active behavioral condition, however, the techniques differed significantly in the ability to preserve the evoked potential and reduce noise. Consequently, strict artifact rejection levels resulted in an inherent underestimation of wave V amplitudes when compared with the Bayesian approach. CONCLUSION: Artifact rejection had a detrimental effect on waveform morphology of the ABR. This could lead to difficulty in ABR interpretation when patients are active and ultimately result in diagnostic errors.

Context: The female athlete triad describes the interrelatedness of energy availability, menstrual function, and bone density. Although associations between triad components and musculoskeletal injury (INJ) have been reported in collegiate athletes, limited information exists about menstrual irregularity (Ml) and INJ in the high school population. Objective: To determine the prevalence of and relationship between Ml and INJ in high school athletes. Design: Cross-sectional study. Setting: High schools. Patients or Other Participants: The sample consisted of 249 female athletes from 3 high schools who competed in 33 interscholastic, school-sponsored sport teams, dance teams, and cheerleading or pom-pon squad during the 2006-2007 school year. Each athlete remained on the roster throughout the season. Main Outcome Measure(s): Participants completed a survey regarding injury type, number of days of sport participation missed, and menstrual history in the past year. Results: The prevalences of Ml and INJ were 19.7% and 63.1%, respectively. Athletes who reported Ml sustained; higher percentage of severe injuries (missing \textgreater22 days of practice or competition) than did athletes who reported normal menses. Although the trend was not significant, athletes with Ml were almost 3 times more likely to sustain an injury resulting in 7 or more days of time lost from sport (odds ratio = 2.7, 9591 confidence interval = 0.8, 8.8) than those who sustained an in jury resulting in 7 or fewer days of time lost. Conclusions: The incidences of Ml and INJ in this high school population during the study period were high. Athlete; who reported Ml sustained a higher percentage of severe injuries than did athletes who reported normal menses. Education programs to increase knowledge and improve management o Ml and its potential effects on injury in female high school athletes are warranted.

Background/Objective: The use of electronic cigarettes (e-cigarettes) among young adults has been increasing, leading to concern due to unknown health effects. The purpose of the current study is to replicate and expand research on two contrasting models of e-cigarette use: risk model and conventional exploration model. Methods: An anonymous online survey was distributed at a midwestern university in fall 2015. There were 3,626 respondents, aged between 18 and 25, who answered the study's measures: sensation seeking, risk perception, public use attitudes, and policy views. Results: Respondents were categorized into mutually exclusive groups: nonuser (58.8%), e-cigarette only user (24.2%), cigarette only user (2.7%), and dual user (13.2%). Lending support to the risk model, higher disinhibition and endorsing e-cigarette use in public was associated with lower odds of being nonusers compared to e-cigarette only users. Support for the conventional model was found with higher perceived likelihood of getting heart disease, a risk of harm, and a risk of addiction due to e-cigarette use being associated with higher odds of being nonusers compared to e-cigarette only users. Conclusions: Results provide some support for both models. Findings can be used to inform prevention and intervention programs and services.

Background: Ulnar collateral ligament (UCL) injuries represent one of the most common impairments to the throwing arm of professional pitchers. Return to play and postoperative performance metrics have been studied extensively, but pitch selection before and after surgery has not been evaluated. Purpose/Hypothesis: This study aimed to characterize the effects of UCL reconstruction on pitch selection in Major League Baseball (MLB) pitchers. We hypothesized that pitchers will throw fewer fastballs and a greater percentage of off-speed pitches after undergoing UCL reconstruction. Study Design: Retrospective cohort study; Level of evidence, 3. Methods: Using publicly available data, we evaluated MLB pitchers who underwent UCL reconstruction between 2003 and 2014. Pitching data were collected for the 2 seasons before UCL reconstruction as well as the first 2 seasons after reconstruction; the data consisted of the total number of pitches thrown and the percentage of fastballs, curveballs, changeups, and sliders. Repeated-measures analysis of variance was used with post hoc least significant difference pairwise t tests to evaluate for statistical significance at P \textless .05. Results: Overall, 87 pitchers (mean age, 28.2 +/- 3.5 years) met all inclusion and exclusion criteria. There was a statistically significant difference in the total number of pitches thrown before and after surgery (P \textless .01) as well as in the percentage of fastballs thrown before and after surgery (P = .02). There was also a statistically significant increase in the use of curveballs between 1 and 2 years postoperatively (7.5% and 8.8%, respectively; P = .01). No other findings were statistically significant. Conclusion: Pitchers who underwent UCL reconstruction were shown to have a statistically significant decline in the percentage of fastballs thrown postoperatively as compared with before injury, with a compensatory trend toward an increased use of curveballs and sliders.
