BACKGROUND: SARS-CoV-2 vaccines are safe and effective against infection and severe COVID-19 disease worldwide. Certain co-morbid conditions cause immune dysfunction and may reduce immune response to vaccination. In contrast, those with co-morbidities may practice infection prevention strategies. Thus, the real-world clinical impact of co-morbidities on SARS-CoV-2 infection in the recent post-vaccination period is not well established. This study was performed to understand the epidemiology of Omicron breakthrough infection and evaluate associations with number of comorbidities in a vaccinated and boosted population.
RESULTS: A retrospective clinical cohort study was performed utilizing the Northwestern Medicine Enterprise Data Warehouse. Our study population was identified as fully vaccinated adults with at least one booster. The primary risk factor of interest was the number of co-morbidities. The primary outcome was the incidence and time to the first positive SARS-CoV-2 molecular test in the Omicron predominant era. Multivariable Cox modeling analyses to determine the hazard of SARS-CoV-2 infection were stratified by calendar time (Period 1: January 1 -June 30, 2022; Period 2: July 1 -December 31, 2022) due to violations in the proportional hazards assumption. In total, 133,191 patients were analyzed. During Period 1, having 3+ comorbidities was associated with increased hazard for breakthrough (HR = 1.16 CI 1.08-1.26). During Period 2 of the study, having 2 comorbidities (HR = 1.45 95% CI 1.26-1.67) and having 3+ comorbidities (HR 1.73, 95% CI 1.51-1.97) were associated with increased hazard for Omicron breakthrough. Older age was associated with decreased hazard in Period 1 of follow-up. Interaction terms for calendar time indicated significant changes in hazard for many factors between the first and second halves of the follow-up period.
CONCLUSIONS: Omicron breakthrough is common with significantly higher risk for our most vulnerable patients with multiple co-morbidities. Age plays an important role in breakthrough infection with the highest incidence among young adults, which may be due to age-related behavioral factors. These findings reflect real-world differences in immunity and exposure risk behaviors for populations vulnerable to COVID-19.

Insect growth regulators, like S-methoprene, are heavily relied upon worldwide for larval mosquito chemical control due to their target specificity and long-lasting effects. In this study, susceptibility to S-methoprene was evaluated in Culex pipiens, a globally important vector species. Populations from 14 sites throughout the Chicago area with a long history of S-methoprene use and two sites with minimal use in Wisconsin were examined. Using a bioassay methodology and probit analyses, LC50 and LC90 values were calculated and compared to a susceptible laboratory strain to develop resistance ratios, then categorized for resistance intensity. The resistance ratios observed required the addition of another category, termed \'extreme\' resistance, indicating resistance ratios greater than 100. \'Low\' to \'extreme\' levels of resistance to S-methoprene were detected throughout Illinois populations, with resistance ratios ranging from 2.33 to 1010.52. Resistance was not detected in populations where S-methoprene pressure has been very limited. These \'extreme\' resistance ratios observed have never been documented in a wild vector species mosquito population. The relationships between historical S-methoprene use, resistance detected with laboratory bioassays, and the potential for field product failure remain unclear. However, the profound resistance detected here demonstrates a potential critical threat to protecting public health from mosquito-borne diseases.

BACKGROUND: Overdose deaths continue to rise within the United States, despite effective treatments such as buprenorphine and methadone for opioid use disorder (OUD). Mobile medical units with the ability to dispense buprenorphine have been developed to engage patients and eliminate barriers to accessing OUD treatment. This study reports survey responses of patients of a mobile medical unit dispensing buprenorphine in areas of Chicago, IL with high overdose rates.
METHODS: All patients who were dispensed buprenorphine via the mobile medical unit were invited to participate in a 7-item anonymous survey between May 24, 2023, and August 25, 2023. The survey included 5-point satisfaction scale, multiple-choice, and open-ended questions. Outcomes included satisfaction with buprenorphine dispensing from the mobile medical unit, satisfaction with filling buprenorphine at a pharmacy in the past, barriers experienced at pharmacies when filling buprenorphine, and whether the client would have started treatment that day if the mobile medical unit had not been present. Satisfaction scale and multiple-choice question responses were assessed using descriptive statistics. Wilcoxon signed-rank test was used to compare median satisfaction levels between receiving buprenorphine from the mobile medical unit versus filling a buprenorphine prescription at a community pharmacy. Open-ended questions were analyzed qualitatively using inductive thematic analysis.
RESULTS: 106 unique patients were dispensed buprenorphine from the mobile unit during the study period. Of these patients, 54 (51%) completed the survey. Respondents reported high satisfaction with the buprenorphine dispensing process as a part of a mobile medical unit. Of those who had previously filled buprenorphine at a pharmacy, 83% reported at least one barrier, with delays in prescription dispensing from a community pharmacy, lack of transportation to/from the pharmacy, and opioid withdrawal symptoms being the most common barriers. 87% reported they would not have started buprenorphine that same day if the mobile medical unit had not been present. Nearly half of survey participants reported having taken buprenorphine that was not prescribed to them. Qualitative analysis of open-ended survey responses noted the importance of convenient accessibility, comprehensive care, and a non-judgmental environment.
CONCLUSIONS: Mobile medical units that dispense buprenorphine are an innovative model to reach patients with OUD who have significant treatment access barriers. This study found that patients who experienced barriers to accessing buprenorphine from a pharmacy were highly satisfied with the mobile medical unit\'s buprenorphine dispensing process. Programs seeking to develop mobile buprenorphine dispensing programs should consider patient priorities of accessibility, comprehensive care, and welcoming, non-judgmental environments.

OBJECTIVE: To study the prevalence of attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in individuals with dystrophinopathy compared with the general population.
METHODS: Retrospective chart review to examine the prevalence of ADHD and ASD, diagnosed both formally and informally, in individuals with dystrophinopathy receiving care in the multidisciplinary neuromuscular clinic at the Ann and Robert H. Lurie Children\'s Hospital of Chicago.
RESULTS: Our results demonstrate an ADHD prevalence of 18.40% and ASD prevalence of 12.73%, both significantly higher than those reported for the general population. Our results revealed a significant association between ADHD diagnosis and a positive family history but did not show a statistically significant association between prevalence of ADHD and the use of steroids.
CONCLUSIONS: Based on our current study results, we plan to further evaluate the prevalence, in a prospective cross-sectional manner, using validated screens for both ADHD and ASD.

Learning theories provide explanations for domestic violence; they can also aid in our understanding of the relation between contact sports and domestic violence. Notably, language used during sporting events and athletes\' behaviors being rewarded both on and off the field can influence the behaviors of viewers. Adubato (2016) found a statistically significant relation between an increase in domestic violence arrests and the kick-off times of Philadelphia Eagles football games. Here, we replicate and extend this work to Chicago and Boston. We examine quantitative, hourly data from the Chicago and Boston Police Departments and compare mean domestic violence arrests in an 8-hour period from the average Bears\' and Patriots\' (football) kick-off times, respectively, to the same time period on non-football Sundays, major holidays, and days of rival Blackhawks\' and Bruins\' (hockey) games, respectively. Results show a significant difference in average domestic violence arrests between hockey games and non-football Sundays in Chicago only. This work highlights the importance of context in examining domestic violence nationally and has implications for domestic violence policies in professional sports\' organizations.

OBJECTIVE: HIV biomedical intervention uptake is suboptimal among Black sexually minoritized men (SMM) and transgender women (TW). Venues where people meet and interact shape HIV-related risk and prevention behaviors. We aimed to construct GPS-defined venue-based affiliation networks and identify the unique set of venues that could maximize reach of HIV biomedical interventions among Black SMM and TW.
METHODS: We used baseline survey and GPS data from 272 Black SMM and TW in the Neighborhoods and Networks (N2) Cohort Study in Chicago, Illinois (2018-2019). We mapped participants\' GPS data to the nearest pre-identified SMM- and TW-friendly venue (n = 222) to construct affiliation networks. Network analyses were performed to identify influential venues that can yield high reach to intervention candidates.
RESULTS: Participants were affiliated with 75.5 % of all pre-identified venues based on GPS data. Two influential venues were identified in the non-PrEP use network, which when combined, could reach 52.5 % of participants not taking PrEP. Participants that could be reached through these two influential venues reported more non-main sex partners than participants not affiliated with either venue (p = 0.049).
CONCLUSIONS: We demonstrate a potential for GPS-defined venue-based affiliation networks to identify unique combinations of venues that could maximize the impact of HIV prevention interventions.

BACKGROUND: In 2013, the Chicago Public Schools (CPS) district passed a policy requiring schools to deliver comprehensive sexual health education (SHE) to all K-12th grade students. A performance improvement case study was conducted in the 2019-2020 school year to evaluate the implementation of the policy and identify lessons learned to support implementation in schools.
METHODS: Key informant interviews were conducted with 11 school principals and 29 teachers to discuss SHE implementation at their school. Interviews were recorded, transcribed, and analyzed to assess school and classroom factors that affect implementation. Themes that cut across these factors were then identified and summarized by 2 evaluators.
RESULTS: The following themes were identified across key informant interviews: (a) principal prioritization of SHE helps ensure SHE is implemented, (b) the expansion of school and teacher capacity facilitates SHE implementation, and (c) the creation of accountability mechanisms in classrooms and schools fosters adherence to SHE policy.
CONCLUSIONS: Principals play a crucial role in building capacity to deliver SHE and ensuring SHE accountability mechanisms are implemented in their school. CPS is using these findings to adjust technical assistance and resources provided to principals and SHE instructors.

BACKGROUND: Community-partnered participatory research (CPPR) is a research approach that supports equitable collaboration of community and academic co-leaders in research and policy. Despite CPPR\'s 25-year history, infrastructure supporting community members in bidirectional learning has not been formalized.
OBJECTIVE: This paper describes processes and procedures using CPPR to plan conferences to develop community leadership training infrastructure.
METHODS: We utilized rapid ethnographic analysis to examine conference planning processes for community leadership in CPPR. Community and academic leaders in Los Angeles, New Orleans, and Chicago met weekly over two months to plan, given COVID-19, three Zoom conferences on a leadership training institute for CPPR, with planning for (1) community co-leadership in research and policy; (2) local and national CPPR programs; and (3) models for bidirectional training.
RESULTS: The planning process emphasized bidirectional learning for community and academic members for research and services/policy to benefit communities, within a Community Leadership Institute for Equity (C-LIFE) to promote equity and power sharing for community leaders. The planning process identified major themes of framing of C-LIFE conference planning goals, developing the conference structure, promoting equity and diversity, envisioning the future of CPPR, challenges, collaborations, future curriculum ideas for C-LIFE, evaluation and next-steps for Zoom conferences in November 2020.
CONCLUSIONS: It was feasible to use CPPR to plan Zoom conferences to promote community leadership training across multiple sites. Key planning themes included promoting equity, addressing structural racism, bidirectional learning and integrating community, academic, and policy priorities with community co-leaders as change agents.
