A Pilot Study: Emergency Medical Services-Related Violence in the Out-of-Hospital Setting in Southeast Michigan.

BACKGROUND: Emergency Medical Services (EMS) personnel in the out-of-hospital setting continue to be at high risk for violence, in spite of continued research on a national scale. OBJECTIVE: Our aim was to determine the prevalence and type of violence perpetrated against Southeast Michigan EMS personnel, and characteristics of victims in the out-of-hospital setting. METHODS: EMS personnel from urban and suburban counties in Southeastern Michigan were surveyed online about their experience with violence, including description and outcomes, while working in the out-of-hospital setting within the previous 6 months. Gift card incentive and recruitment scripts were provided and read to participants. This was a pilot study that was limited to 150 respondents and ran for 3 months. Descriptive statistical analysis was done with an odds ratio, p value, and two-sample independent t-test analysis. RESULTS: There were 137 surveys respondents. Most respondents, 75 of 128 (58.6%) reported being a victim of violence within the previous 6 months. Perpetrators were primarily patients and occasionally family members. Substance abuse or mental health issues were frequently associated with violence. Although not common, women reported violence perpetrated by a coworker more often than men (odds ratio 5.17; 95% confidence interval 1.67-16.0). Only 55 of 117 respondents (47.0%) felt that the training did an adequate job protecting them from violence. CONCLUSIONS: More than one-half of responding EMS personnel experienced work-related violence within the previous 6 months in Southeast Michigan. This high rate of violence supports the need for additional research and policies that ensure the safety of EMS providers in this region.

Gender disparity in speakers at a major academic emergency medicine conference.

BACKGROUND: Although women make up a substantial portion of the workforce in emergency medicine, they remain under-represented in academia. METHODS: This study investigates trends in the representation of female speakers at the American College of Emergency Physicians scientific assembly-the largest academic emergency medicine conference in the world. Publication profiles, speaking duration and gender composition of speakers were collected and compared over a 3-year period. RESULTS: The authors described increased representation of female speakers at the conference from 2016 to 2018, as well as an upward trend in women's actual speaking time. CONCLUSION: This upward trend in women's representation may translate to more opportunities for female engagement in academic emergency medicine. Despite the increasing representation of women, male speakers outnumbered female speakers all 3 years, demonstrating that a speaker gender gap persists in academic emergency medicine.

Safety proposals for freediving time limits should consider the metabolic-rate dependence of oxygen stores depletion.

INTRODUCTION: There is no required training for breath-hold diving, making dissemination of safety protocols difficult. A recommended breath-hold dive time limit of 60 s was proposed for amateur divers. However, this does not consider the metabolic-rate dependence of oxygen stores depletion. We aimed to measure the effect of apnoea time and metabolic rate on arterial and tissue oxygenation. METHODS: Fifty healthy participants (23 (SD 3) y, 22 women) completed four periods of apnoea for 60 s (or to tolerable limit) during rest and cycle ergometry at 20, 40, and 60 W. Apnoea was initiated after hyperventilation to achieve PETCO2 of approximately 25 mmHg. Pulse oximetry, frontal lobe oxygenation, and pulmonary gas exchange were measured throughout. We defined hypoxia as SpO2 < 88%. RESULTS: Static and exercise (20, 40, 60 W) breath-hold break times were 57 (SD 7), 50 (11), 48 (11), and 46 (11) s (F [2.432, 119.2] = 32.0, P < 0.01). The rise in PETCO2 from initiation to breaking of apnoea was dependent on metabolic rate (time × metabolic rate interaction; F [3,147] = 38.6, P < 0.0001). The same was true for the fall in SpO2 (F [3,147] = 2.9, P = 0.03). SpO2 fell to < 88% on 14 occasions in eight participants, all of whom were asymptomatic. CONCLUSIONS: Independent of the added complexities of a fall in ambient pressure on ascent, the effect of apnoea time on hypoxia depends on the metabolic rate and is highly variable among individuals. Therefore, we contend that a universally recommended time limit for breath-hold diving or swimming is not useful to guarantee safety.

Women's representation at an academic dermatology conference: trending upwards, but not equal yet.

Although women make up a significant portion of the workforce in dermatology, they remain underrepresented in academia. This study investigates the number of male and female symposium speakers at the American Academy of Dermatology annual meetings over a three-year period and compares research productivity and academic rank between the men and women invited to speak. The results demonstrate a steady increase in the representation of female symposium speakers at the conference from 2016 to 2018, although a higher proportion of invited male speakers hold professorships and leadership positions. This upward trend in women's representation may translate to more opportunities for female engagement in academic dermatology. Although women make up over 60% of residents in dermatology, they are not proportionally represented in this conference sample. This imbalance in representation demonstrates that further interventions to increase the representation of female professors and chairs may be necessary.
