Understanding the relationship between alcohol outlet density and life expectancy in Baltimore City: The role of community violence and community disadvantage

This research investigated the relationship between alcohol outlet density (AOD) and life expectancy, as mediated by community violence and community disadvantage. We used linear regression models to assess bivariate and multivariate relationships. There was a negative bivariate association between liquor store density and average life expectancy (β = â 7.3370, p < 0.001). This relationship was partially attenuated when controlling for community disadvantage and fully attenuated when controlling for community violence. Bars/taverns (i.e., onâ premise) were not associated with average life expectancy (β = â 0.589, p = 0.220). Liquor store density is associated with higher levels of community disadvantage and higher rates of violence, both of which are associated with lower life expectancies. Future research, potential intervention, and current related policies are discussed.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146620/1/jcop22099_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146620/2/jcop22099.pd

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Changes in Attitudes toward Guns and Shootings following Implementation of the Baltimore Safe Streets Intervention

Among youth 15 to 24&nbsp;years of age, homicide and nonfatal shootings are the leading causes of mortality and morbidity. Urban youth's attitudes and perceptions about the use of gun violence to resolve conflict present a major barrier to efforts to reduce gun homicides and nonfatal shootings. The current investigation extends the existing literature on attitudes toward guns and shootings among high-risk youth ages 18 to 24 by measuring perceived norms and viewpoints regarding gun violence in two analogous Baltimore City neighborhoods pre-implementation and 1-year post-implementation of the Safe Streets intervention (adapted from the CeaseFire/Cure Violence intervention). The Safe Streets intervention is designed for communities with high rates of gun violence and utilizes outreach workers to identify and build trusting relationships with youth ages 15 to 24 who are at greatest risk of being involved in gun violence. The outreach workers also position themselves in the community so that they can rapidly intervene in disputes that have the potential to lead to gun violence. Chi-squared tests and exploratory structural equation modeling (ESEM) were used to examine changes in attitudes toward gun violence 1&nbsp;year after the implementation of the Safe Streets intervention. There was a statistically significantly improvement in 43&nbsp;% of the attitudes assessed in the intervention community post-intervention compared to 13&nbsp;% of the attitudes in the control community. There was a statistically significant improvement in the violent attitudes toward personal conflict resolution scale after implementation of the intervention in both the intervention (b = -0.522, p &lt; 0.001) and control community (b = -0.204, p &lt; 0.032). Exposure to the intervention (e.g., seeing stop shooting signs in your neighborhood) was also associated with the nonviolent attitudes toward conflict scale. Overall, the study found greater improvement in attitudes toward violence in the intervention community following the implementation of the Safe Streets program. These findings offer promising insights into future community violence prevention efforts

Racial Differences in 30-Day Reintubation After Head and Neck Surgery

Background This study aimed to examine the association of race and ethnicity with 30-day unplanned reintubation following head and neck surgery. Methodology A retrospective analysis of head and neck surgery patients aged greater than or equal to 18 years was extracted from the American College of Surgeons National Surgical Quality Improvement Program database from 2015 to 2020. Patient demographics, comorbidities, and 30-day reintubation were included in the analysis. Pearson's chi-square and independent samples t-test were used to compare reintubation cohorts. Multivariable logistic regression was used to identify the association of race and ethnicity with 30-day reintubation. Results Of the total 108,442 head and neck surgery cases included, 74.9% of patients were non-Hispanic White, 17.3% were non-Hispanic Black, and 7.7% were Hispanic. The overall 30-day reintubation rate was 0.33%. After adjusting for age, body mass index,&nbsp;sex, and comorbidities, non-Hispanic Black patients had increased 30-day reintubation compared to non-Hispanic White patients (odds ratio [OR] = 2.14, 95% confidence interval [CI] 1.70-2.69, and P&nbsp;&lt; 0.0001). There was no difference in 30-day reintubation for Hispanic patients compared to non-Hispanic White patients (OR = 1.08, 95% CI 0.67-1.65, and P&nbsp;= 0.747). Conclusions This analysis showed that non-Hispanic Black patients disproportionately had higher odds of 30-day reintubation following head and neck surgery. Hispanic ethnicity was not associated with increased odds of 30-day reintubation. More studies are needed to investigate the reasons for these racial differences
