The racial composition of road users, traffic citations, and police stops.

This paper exploits the potential of Global Positioning System datasets sourced from mobile phones to estimate the racial composition of road users, leveraging data from their respective Census block group. The racial composition data encompasses approximately 46 million trips in the Chicago metropolitan region. The research focuses on the relationship between camera tickets and racial composition of drivers vs. police stops for traffic citations and the racial composition in these locations. Black drivers exhibit a higher likelihood of being ticketed by automated speed cameras and of being stopped for moving violations on roads, irrespective of the proportion of White drivers present. The research observes that this correlation attenuates as the proportion of White drivers on the road increases. The citation rate measured by cameras better matches the racial composition of road users on the links with cameras than do stops by police officers. This study therefore presents an important contribution to understanding racial disparities in moving violation stops, with implications for policy interventions and social justice reforms.

Health Belief Model to Assess Mpox Knowledge, Attitudes, and Practices among Residents and Staff, Cook County Jail, Illinois, USA, July-August 2022.

In summer 2022, a case of mpox was confirmed in a resident at the Cook County Jail (CCJ) in Chicago, Illinois, USA. We conducted in-depth interviews with CCJ residents and staff to assess mpox knowledge, attitudes, and practices; hygiene and cleaning practices; and risk behaviors. We characterized findings by using health belief model constructs. CCJ residents and staff perceived increased mpox susceptibility but were unsure about infection severity; they were motivated to protect themselves but reported limited mpox knowledge as a barrier and desired clear communication to inform preventive actions. Residents expressed low self-efficacy to protect themselves because of contextual factors, including perceived limited access to cleaning, disinfecting, and hygiene items. Our findings suggest correctional facilities can support disease prevention by providing actionable and tailored messages; educating residents and staff about risk and vaccination options; and ensuring access to and training for hygiene, cleaning, and disinfecting supplies.

Reducing severe maternal morbidity for birthing persons with severe hypertension through a statewide quality improvement initiative.

BACKGROUND: Hypertensive disorders of pregnancy are a leading preventable cause of severe maternal morbidity and maternal mortality worldwide. OBJECTIVE: To assess the improvement in hospital care processes and patient outcomes associated with hypertensive disorders of pregnancy after introduction of a statewide Severe Maternal Hypertension Quality Improvement Initiative. STUDY DESIGN: A prospective cohort design comparing outcomes before and after introduction of the Illinois Perinatal Quality Collaborative statewide hypertension quality improvement initiative among 108 hospitals across Illinois. Participating hospitals recorded data for all cases of new-onset severe hypertension (>160 mm Hg systolic or >110 mm Hg diastolic) during pregnancy through 6 weeks postpartum from May 2016 to December 2017. Introduction of the statewide quality improvement initiative included implementation of severe maternal hypertension protocols, standardized patient education and discharge planning, rapid access to medications and standardized treatment order sets, and provider and nurse education. The main outcome measure was the reduction of severe maternal morbidity for pregnant/postpartum patients with severe hypertension. Key process measures include time to treatment of severe hypertension, frequency of provider/nurse debriefs, appropriate patient education, and early postpartum follow-up. RESULTS: Data were reported for 8073 cases of severe maternal hypertension. The frequency of patients with new-onset severe hypertension treated within 60 minutes increased from 41% baseline to 87% (P<.001) at the end of the initiative. The initiative was associated with increased proportion of patients receiving preeclampsia education at discharge (41% to 89%; P<.001), scheduling follow-up appointments within 10 days of discharge (68% to 83%; P<.001), and having a care team debrief after severe hypertension was diagnosed (17% to 59%; P<.001). Conversely, severe maternal morbidity was reduced from 11.5% baseline to 8.4% (P<.002) at the end of the study period. Illinois hospitals have achieved time to treatment goal regardless of hospital characteristics including geography, birth volume, and patient mix. CONCLUSION: Introduction of a statewide quality improvement effort was associated with improved time to treatment of severe hypertension and increased frequency of provider/nurse debriefs, appropriate patient education, and early postpartum follow-up scheduled at discharge, and reduced severe maternal morbidity.

SARS-CoV-2 Reinfection Risk in Persons with HIV, Chicago, Illinois, USA, 2020-2022.

Understanding if persons with HIV (PWH) have a higher risk for SARS-CoV-2 reinfection may help tailor future COVID-19 public health guidance. To determine whether HIV infection was associated with increased risk for SARS-CoV-2 reinfection, we followed adult residents of Chicago, Illinois, USA, with SARS-CoV-2 longitudinally from their first reported infection through May 31, 2022. We matched SARS-CoV-2 laboratory data and COVID-19 vaccine administration data to Chicago's Enhanced HIV/AIDS Reporting System. Among 453,587 Chicago residents with SARS-CoV-2, a total of 5% experienced a SARS-CoV-2 reinfection, including 192/2,886 (7%) PWH and 23,642/450,701 (5%) persons without HIV. We observed higher SARS-CoV-2 reinfection incidence rates among PWH (66 [95% CI 57-77] cases/1,000 person-years) than PWOH (50 [95% CI 49-51] cases/1,000 person-years). PWH had a higher adjusted rate of SARS-CoV-2 reinfection (1.46, 95% CI 1.27-1.68) than those without HIV. PWH should follow the recommended COVID-19 vaccine schedule, including booster doses.

Albert Feng: father, friend, scientist, innovator (1944-2021).

Albert S.-H. Feng was an outstanding family man and brilliant scientist, with a creative mind, a gift for dealing with people of all types, and a warm, personable demeanor. He was blessed with many talents, making him a sought-after colleague and collaborator. His love for people and travel took him to many destinations around the world where he studied the neuroethology of frog and bat communication both in the field and in the lab. He has made many fundamental contributions to our understanding of the vertebrate auditory system. These include characterizing the "delay-tuned" neurons in the bat midbrain underlying target detection, and in discovering several terrestrial amphibians in which the upper limit of hearing extends well into the ultrasonic range, forever changing our long-held perception of frogs as "low-frequency animals".

Rural-Urban Disparities in HPV Vaccination Coverage Among Adolescents in the Central Part of the State of Illinois, USA.

Human Papillomavirus (HPV) is associated with six cancers and widespread immunization with HPV vaccine could reduce the number of these cancers. Although HPV vaccination rates are available for the state of Illinois and the city of Chicago, data are limited for specific areas. We assessed rates of HPV vaccine initiation and completion among adolescents in central Illinois and identified factors associated with initiation and completion. This was a retrospective study of adolescents (aged 11-17) who receive care at the Southern Illinois University Medicine Department of Pediatrics. The outcome variables were HPV vaccination initiation (receipt of ≥ 1 dose) and completion (receipt of ≥ 2 or 3 doses, depending on age of initiation). Multivariable logistic regressions were used to identify factors associated with HPV vaccine uptake. A total of 9,351 adolescents were included in the study. Overall, HPV vaccine initiation was 46.2% and completion was 24.7%. In adjusted analyses, adolescents residing in rural areas were 38% and 24% less likely to initiate (aOR = 0.62; 95 CI: 0.54-0.72) and complete (aOR = 0.76; 95 CI: 0.65-0.88) the HPV vaccine compared with those residing in urban areas. Similarly, adolescents were less likely to initiate and complete the HPV vaccine if they were not update to date on the hepatitis A, meningococcal, or Tdap vaccinations. HPV vaccination rates in central Illinois were low, and far below the national average and the Illinois state average. Future directions should include interventions to increase HPV vaccine uptake, particularly in rural areas.

Multistate Outbreak of Infection with SARS-CoV-2 Omicron Variant after Event in Chicago, Illinois, USA, 2021.

Bars and restaurants are high-risk settings for SARS-CoV-2 transmission. A multistate outbreak after a bar gathering in Chicago, Illinois, USA, highlights Omicron variant transmissibility, the value of local genomic surveillance and interstate coordination, vaccination value, and the potential for rapid transmission of a novel variant across multiple states after 1 event.

Transmission Dynamics of Large Coronavirus Disease Outbreak in Homeless Shelter, Chicago, Illinois, USA, 2020.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has the potential for rapid transmission in congregate settings. We describe the multidisciplinary response to an outbreak of coronavirus disease (COVID-19) in a large homeless shelter in Chicago, Illinois, USA. The response to the outbreak included 4 rounds of mass PCR testing of all staff and residents and subsequent isolation of persons who tested positive for SARS-CoV-2. We further describe the dynamics of the shelter outbreak by fitting a modified susceptible-exposed-infectious-recovered compartmental model incorporating the widespread SARS-CoV-2 testing and isolation measures implemented in this shelter. Our model demonstrates that rapid transmission of COVID-19 in the shelter occurred before the outbreak was detected; rates of transmission declined after widespread testing and isolation measures were put in place. Overall, we demonstrate the feasibility of mass PCR testing and isolation in congregate settings and suggest the necessity of prompt response to suspected COVID-19 outbreaks in homeless shelters.

Structural racism and COVID-19 response: higher risk of exposure drives disparate COVID-19 deaths among Black and Hispanic/Latinx residents of Illinois, USA.

BACKGROUND: Structural racism has driven and continues to drive policies that create the social, economic, and community factors resulting in residential segregation, lack of access to adequate healthcare, and lack of employment opportunities that would allow economic mobility. This results in overall poorer population health for minoritized people. In 2020, Black and Hispanic/Latinx communities throughout the United States, including the state of Illinois, experienced disproportionately high rates of COVID-19 cases and deaths. Public health officials in Illinois implemented targeted programs at state and local levels to increase intervention access and reduce disparities. METHODS: To quantify how disparities in COVID outcomes evolved through the epidemic, data on SARS-CoV-2 diagnostic tests, COVID-19 cases, and COVID-19 deaths were obtained from the Illinois National Electronic Disease Surveillance System for the period from March 1 to December 31, 2020. Relative risks of COVID-19 cases and deaths were calculated for Black and Hispanic/Latinx vs. White residents, stratified by age group and epidemic interval. Deaths attributable to racial/ethnic disparities in incidence and case fatality were estimated with counterfactual simulations. RESULTS: Disparities in case and death rates became less drastic after May 2020, but did not disappear, and were more pronounced at younger ages. From March to May of 2020, the risk of a COVID-19 case for Black and Hispanic/Latinx populations was more than twice that of Whites across all age groups. The relative risk of COVID-19 death reached above 10 for Black and Hispanic/Latinx individuals under 50 years of age compared to age-matched Whites in the early epidemic. In all Illinois counties, relative risk of a COVID-19 case was the same or significantly increased for minoritized populations compared to the White population. 79.3 and 86.7% of disparities in deaths among Black and Hispanic/Latinx populations, respectively, were attributable to differences in age-adjusted incidence compared to White populations rather than differences in case fatality ratios. CONCLUSIONS: Racial and ethnic disparities in the COVID-19 pandemic are products of society, not biology. Considering age and geography in addition to race/ethnicity can help to identify the structural factors driving poorer outcomes for certain groups. Studies and policies aimed at reducing inequalities in disease exposure may reduce disparities in mortality more than those focused on drivers of case fatality.

Provider and community stakeholder perspectives of expanding Medicaid coverage of abortion in Illinois.

BACKGROUND: Many people seeking abortion encounter financial difficulties that delay or prevent them from accessing care. Although some patients qualify for Medicaid (a public program that can help cover health care costs), laws in some states restrict the use of Medicaid for abortion care. In 2017, Illinois passed House Bill 40 (HB-40), which allowed patients with Medicaid to receive coverage for their abortion. This study aimed to understand how HB-40 affected abortion affordability from the perspectives of individuals that work directly or indirectly with abortion patients or facilities providing abortion care. METHODS: We conducted interviews with clinicians and administrators from facilities that provided abortion services; staff from organizations that provided resources to abortion providers or patients; and individuals at organizations involved in the passage and/or implementation of HB-40. Interviews were audio-recorded and transcribed. We created codes based on the interview guides, coded each transcript using the web application Dedoose, and summarized findings by code. RESULTS: Interviews were conducted with 38 participants. Participants reflected that HB-40 seemed to remove a significant financial barrier for Medicaid recipients and improve the experience for patients seeking abortion care. Participants also described how the law led to a shift in resource allocation, allowing financial support to be directed towards uninsured patients. Some participants thought HB-40 might contribute to a reduction in abortion stigma. Despite the perceived positive impacts of the law, participants noted a lack of public knowledge about HB-40, as well as confusing or cumbersome insurance-related processes, could diminish the law's impact. Participants also highlighted persisting barriers to abortion utilization for minors, recent and undocumented immigrants, and people residing in rural areas, even after the passage of HB-40. CONCLUSIONS: HB-40 was perceived to improve the affordability of abortion. However, participants identified additional obstacles to abortion care in Illinois that weakened the impact of HB-40 for patients and required further action, Findings suggest that policymakers must also consider how insurance coverage can be disrupted by other legal barriers for historically excluded populations and ensure clear information on Medicaid enrollment and abortion coverage is widely disseminated.

Ecosystem responses to aquatic invasive species management: A synthesis of two decades of bigheaded carp suppression in a large river.

The invasion of silver carp (Hypophthalmichthys molitrix) and bighead carp (H. nobilis) or "bigheaded carps" has caused extensive ecological and economic harm throughout the Mississippi River and its tributaries. To prevent their continued spread upstream toward the Great Lakes, intense commercial harvest was implemented on the Illinois River, a large tributary that connects the Mississippi River to Lake Michigan. Since implementation, harvest has reduced densities at the invasion front while also presenting an opportunity to generate a synthesis on ecosystem resilience in the face of accelerating invasion. Resilience, the ability of an ecosystem to recover after perturbation, was observed at local scales and within some taxa but has yet to manifest at a river-wide scale and often co-varied with abiotic environmental or seasonal factors. Thus, while intensive harvest has limited further spread of bigheaded carps, and evidence of additional secondary ecosystem benefits exists, opportunities remain to identify potential pathways that could spread such ecosystem benefits even farther.

Resisting-Accepting-Directing: Ecosystem Management Guided by an Ecological Resilience Assessment.

As anthropogenic influences push ecosystems past tipping points and into new regimes, complex management decisions are complicated by rapid ecosystem changes that may be difficult to reverse. For managers who grapple with how to manage ecosystems under novel conditions and heightened uncertainty, advancing our understanding of regime shifts is paramount. As part of an ecological resilience assessment, researchers and managers have collaborated to identify alternate regimes and build an understanding of the thresholds and factors that govern regime shifts in the Upper Mississippi River System. To describe the management implications of our assessment, we integrate our findings with the recently developed resist-accept-direct (RAD) framework that explicitly acknowledges ecosystem regime change and outlines management approaches of resisting change, accepting change, or directing change. More specifically, we developed guidance for using knowledge of desirability of current conditions, distance to thresholds, and general resilience (that is, an ecosystem's capacity to cope with uncertain disturbances) to navigate the RAD framework. We applied this guidance to outline strategies that resist, accept, or direct change in the context of management of aquatic vegetation, floodplain vegetation, and fish communities across nearly 2000 river kilometers. We provide a case study for how knowledge of ecological dynamics can aid in assessing which management approach(es) are likely to be most ecologically feasible in a changing world. Continued learning from management decisions will be critical to advance our understanding of how ecosystems respond and inform the management of ecosystems for desirable and resilient outcomes.

Dispelling a Myth: Reevaluating the Predictive Validity of Rape Myth Acceptance for Likelihood of Engaging in Sexual Violence.

Sexual violence prevention on college campuses has received significant recent attention. A prevalent intervention paradigm has centered around re-educating young people around consent and reduce endorsement of "rape myths," based on the correlation between rape myths and sexual violence incidents. Yet many of these programs have not measurably reduced sexual assaults. We evaluated the predictive value of a rape myth measure, as compared with other predictors (criminal history, childhood victimization, aggressive tendencies, substance use, and empathy), in predicting self-reported acts of forcible and incapacitated sexual assault in college-age men (N = 304) from 45 U.S. states. Across three logistic regression model pairs, rape myths were weakly associated with violence when considered as sole predictors. However, this predictive power dissipated when other predictors were included. Comprehensive models accounted significantly better for variability in outcomes; with criminal history demonstrating consistent predictive effects. Based on these findings, we recommend further research into prevention programming based on other predictors of violence.

Creating a Culture of Breastfeeding Support and Continuity of Care in Central Illinois.

Central Illinois breastfeeding rates fall short of the recommendation to breastfeed exclusively through 6 months, and Black, low-income, and rural families disproportionately experience low rates. A continuity of care framework, which emphasizes interdisciplinary coordination from the prenatal period through weaning, can support breastfeeding. This case study describes an innovative practice model informed by the Collective Impact Model (CIM) designed to promote breastfeeding continuity of care and community support in Central Illinois. Development and maintenance of the Central Illinois Breastfeeding Professional Network (CIBPN), a network of diverse public health practitioners, leveraged CIM principles. The CIBPN began with influential Breastfeeding Champions, identified through the Illinois State Physical Activity and Nutrition program. Champions convened Central Illinois breastfeeding allies and led the CIBPN to coalesce around a common agenda and engage in mutually reinforcing activities. Linked breastfeeding data for families giving birth at a Central Illinois hospital and receiving postnatal care at a health center were analyzed as a snapshot of CIBPN initiatives. The CIBPN engaged at least 135 practitioners and more than 27 organizations. At least 33 people received advanced breastfeeding training, and many professional development opportunities were offered. Numerous breastfeeding support improvements were made at and between CIBPN sites. Breastfeeding rates at the birthing hospital and health center were stable, including during the COVID-19 pandemic. This article contributes to the practice-based evidence for breastfeeding support by strengthening continuity of care through a successful application of the CIM by public health practitioners.

Spatial, Ecologic, and Clinical Epidemiology of Community-Onset, Ceftriaxone-Resistant Enterobacteriaceae, Cook County, Illinois, USA.

We performed a spatial and mixed ecologic study of community-onset Enterobacteriaceae isolates collected from a public healthcare system in Cook County, Illinois, USA. Individual-level data were collected from the electronic medical record and census tract-level data from the US Census Bureau. Associations between individual- and population-level characteristics and presence of ceftriaxone resistance were determined by logistic regression analysis. Spatial analysis confirmed nonrandom distribution of ceftriaxone resistance across census tracts, which was associated with higher percentages of Hispanic, foreign-born, and uninsured residents. Individual-level analysis showed that ceftriaxone resistance was associated with male sex, an age range of 35-85 years, race or ethnicity other than non-Hispanic Black, inpatient encounter, and percentage of foreign-born residents in the census tract of isolate provenance. Our findings suggest that the likelihood of community-onset ceftriaxone resistance in Enterobacteriaceae is influenced by geographic and population-level variables. The development of effective mitigation strategies might depend on better accounting for these factors.

Coxiella burnetii in 3 Species of Turtles in the Upper Midwest, United States.

Coxiella burnetii, the causative bacterium of the zoonotic disease Q fever, has been documented in many different species. We describe documented turtles that were PCR positive for C. burnetii from multiple locations in Illinois and Wisconsin, USA. Assessing the conservation implications, reservoir potential, and zoonotic risk requires further research.

Geographic and demographic heterogeneity of SARS-CoV-2 diagnostic testing in Illinois, USA, March to December 2020.

BACKGROUND: Availability of SARS-CoV-2 testing in the United States (U.S.) has fluctuated through the course of the COVID-19 pandemic, including in the U.S. state of Illinois. Despite substantial ramp-up in test volume, access to SARS-CoV-2 testing remains limited, heterogeneous, and insufficient to control spread. METHODS: We compared SARS-CoV-2 testing rates across geographic regions, over time, and by demographic characteristics (i.e., age and racial/ethnic groups) in Illinois during March through December 2020. We compared age-matched case fatality ratios and infection fatality ratios through time to estimate the fraction of SARS-CoV-2 infections that have been detected through diagnostic testing. RESULTS: By the end of 2020, initial geographic differences in testing rates had closed substantially. Case fatality ratios were higher in non-Hispanic Black and Hispanic/Latino populations in Illinois relative to non-Hispanic White populations, suggesting that tests were insufficient to accurately capture the true burden of COVID-19 disease in the minority populations during the initial epidemic wave. While testing disparities decreased during 2020, Hispanic/Latino populations consistently remained the least tested at 1.87 tests per 1000 population per day compared with 2.58 and 2.87 for non-Hispanic Black and non-Hispanic White populations, respectively, at the end of 2020. Despite a large expansion in testing since the beginning of the first wave of the epidemic, we estimated that over half (50-80%) of all SARS-CoV-2 infections were not detected by diagnostic testing and continued to evade surveillance. CONCLUSIONS: Systematic methods for identifying relatively under-tested geographic regions and demographic groups may enable policymakers to regularly monitor and evaluate the shifting landscape of diagnostic testing, allowing officials to prioritize allocation of testing resources to reduce disparities in COVID-19 burden and eventually reduce SARS-CoV-2 transmission.

Medicaid expansion and accessibility to healthcare: The Illinois experience.

OBJECTIVE: The study examined the impact that the Medicaid expansion in Illinois had upon insurance rates, access to medical care, dental care, pharmaceuticals, and mental-health counseling between rural and urban counties. DESIGN AND SAMPLE: A serial cross-sectional design was used to assess the health perceptions of adults living in Illinois. MEASURES: Survey data were collected in 2012 (n = 6,149) before the Medicaid expansion in Illinois and in 2015 (n = 3,532) after the expansion from rural (n = 4) and urban counties (n = 4). INTERVENTION: Medicaid expansion reduced the uninsured rate in both rural (16.39%-4.87%) and urban counties (17.05%-5.2%) and improved self-reported health. It also increased access to all types of healthcare, with the biggest increase in dental coverage. RESULTS: Path analysis indicated that the Medicaid expansion ß = -1.03 (p < .01) and poor versus not poor ß = -1.50 (p < .01) were a significant predictor to no healthcare access. Rural verses urban location was not significant (ß = 0.04); however, race/ethnicity was significantly different (p < .01). CONCLUSION: Findings suggest that although the expansion has increased access to care overall, those who are the most vulnerable are still not benefiting equally from the expansion. Therefore, strategies to assist high-risk adults in enrolling and using their Medicaid coverage need to developed and implemented.

Inappropriate Administration of Rabies Postexposure Prophylaxis, Cook County, Illinois, USA.

Administration of rabies postexposure prophylaxis (PEP) is expensive and time-consuming. In suburban Cook County, Illinois, USA, administration of 55.5% of PEP treatments did not follow Advisory Committee on Immunization Practices guidelines. Health department consultation lowered the odds of inappropriate PEP administration by 87%. Providers should consult their health department before prescribing PEP.

Clinical Outcomes of Patients Treated for Candida auris Infections in a Multisite Health System, Illinois, USA.

Candida auris is an emerging fungal pathogen that is typically resistant to fluconazole and is known to cause healthcare-associated outbreaks. We retrospectively reviewed 28 patients who had >1 positive culture for C. auris within a multisite health system in Illinois, USA, during May 2018-April 2019. Twelve of these patients were treated as inpatients for C. auris infections; 10 (83%) met criteria for clinical success, defined as absence of all-cause mortality, C. auris recurrence, and infection-related readmission at 30 days from the first positive culture. The other 2 patients (17%) died within 30 days. Most patients (92%) were empirically treated with micafungin. Four (14%) of 28 total isolates were resistant to fluconazole, 1 (3.6%) was resistant to amphotericin B, and 1 (3.6%) was resistant to echinocandins. Our findings describe low rates of antifungal resistance and favorable clinical outcomes for most C. auris patients.
