What happens in Vegas, stays in your lungs: an assessment of fine particulate matter in casinos that prohibit and allow smoking in Las Vegas, Nevada, USA.

INTRODUCTION: Despite progress in adoption of smoke-free policies, smoking in casinos is allowed in some US states, including Nevada. In 2020, for the first time, a resort-style casino in Las Vegas prohibited smoking voluntarily. This study is the first to assess air quality in this casino and compare results with similar casinos that allow smoking. METHODS: A real-time personal aerosol monitor evaluated particulate matter with a diameter <2.5 µm (PM2.5), a surrogate for secondhand smoke (SHS). PM2.5 was measured at eight Las Vegas casinos, including the smoke-free casino. Each casino was visited twice, and PM2.5 was assessed in smoking-permitted gaming areas and areas where smoking is otherwise prohibited. RESULTS: Average PM2.5 levels were significantly higher in casinos that allow smoking, for both casino gaming areas and areas where smoking is otherwise prohibited (p<0.05). Mean PM2.5 in gaming areas was 164.9 µg/m3 in casinos that allow smoking and 30.5 µg/m3 in the smoke-free casino. Mean PM2.5 in areas where smoking is otherwise prohibited was 83.2 µg/m3 in casinos which allowed smoking in gaming areas, and 48.1 µg/m3 in the smoke-free casino. CONCLUSION: Despite robust evidence about the harms of SHS, tens of thousands of casino employees and tens of millions of tourists are exposed to high levels of SHS in Las Vegas casinos annually, with PM2.5 levels 5.4 times higher in gaming areas when compared with a smoke-free casino. The only way to protect people from SHS exposure is to prohibit smoking in all indoor areas.

Interpersonal Firearm Injury and Death in Portland, Oregon: 2018 Through 2021.

The annual number of firearm injuries in Portland, Oregon has been higher in the years since 2020 than in any prior year in the city's history. This descriptive study analyzed data from Gun Violence Archives (GVA) from January 1, 2018, to December 31, 2021. All incidents in GVA of interpersonal firearm injury that occurred in Portland during this period were analyzed for location, number of people injured or killed, and demographic information for those injured or killed. Comparisons in firearm injury rates were made with Seattle and San Francisco. Interpersonal firearm injuries began to rise after the first COVID-19 case in Oregon; July 2020 had the most injuries in the four-year period. Black men suffered the highest rate of interpersonal fatalities, with more than 11-fold higher rate per 100,000 than White men in every year studied. Portland had a higher rate of total interpersonal firearm injuries and a higher rate of firearm fatalities from 2018 through 2021 compared to Seattle and San Francisco. Neighborhoods near Downtown and those on the Eastside of the city had the highest rates of interpersonal injuries and deaths from firearms, whereas those in the Southwest had the lowest. Defining the burden of disease from interpersonal firearm injuries is a fundamental step in designing future public health research and implementing interventions to curb the trauma brought by interpersonal firearm injury.

By the Seat of Our Pants: the Experience of Small Businesses in the COVID-19 Pandemic, Washington State, March-October 2020.

INTRODUCTION: Most US businesses are small, yet they employ almost half of the nation's workforce. Literature is limited about how small employers (those with 20-250 employees) have made decisions about operating their businesses during the COVID-19 pandemic. We sought to learn how employers made these decisions, what information sources they used, what information they wanted, and to what extent they worked with or used information from their local health department. METHODS: We conducted qualitative, semistructured interviews with 26 employers in Washington State, from August through October 2020. Employers were recruited from 7 counties (4 urban and 3 rural) that were experiencing either higher or lower COVID-19 case rates than Washington State overall. RESULTS: Employers relied heavily on national government resources to make decisions about how to operate their businesses during the COVID-19 pandemic. Few employers had relationships with or turned to their local health departments for information or support. Employers wanted information about COVID-19 safety that was specific to their business operations and industry. Employers also described the emotional toll of COVID-19 and the challenge of trying to make high-stakes decisions with rapidly evolving information. CONCLUSION: Small employers showed little awareness of their local health departments and the information and assistance they could provide. Local health departments could increase their visibility and build relationships with small employers by partnering with them on value-added services such as workplace health promotion. Establishing these relationships could support more rapid collaboration between local health departments and small employers during future public health crises.
