Spatial control of the APC/C ensures the rapid degradation of cyclin B1.

The proper control of mitosis depends on the ubiquitin-mediated degradation of the right mitotic regulator at the right time. This is effected by the Anaphase Promoting Complex/Cyclosome (APC/C) ubiquitin ligase that is regulated by the Spindle Assembly Checkpoint (SAC). The SAC prevents the APC/C from recognising Cyclin B1, the essential anaphase and cytokinesis inhibitor, until all chromosomes are attached to the spindle. Once chromosomes are attached, Cyclin B1 is rapidly degraded to enable chromosome segregation and cytokinesis. We have a good understanding of how the SAC inhibits the APC/C, but relatively little is known about how the APC/C recognises Cyclin B1 as soon as the SAC is turned off. Here, by combining live-cell imaging, in vitro reconstitution biochemistry, and structural analysis by cryo-electron microscopy, we provide evidence that the rapid recognition of Cyclin B1 in metaphase requires spatial regulation of the APC/C. Using fluorescence cross-correlation spectroscopy, we find that Cyclin B1 and the APC/C primarily interact at the mitotic apparatus. We show that this is because Cyclin B1, like the APC/C, binds to nucleosomes, and identify an 'arginine-anchor' in the N-terminus as necessary and sufficient for binding to the nucleosome. Mutating the arginine anchor on Cyclin B1 reduces its interaction with the APC/C and delays its degradation: cells with the mutant, non-nucleosome-binding Cyclin B1 become aneuploid, demonstrating the physiological relevance of our findings. Together, our data demonstrate that mitotic chromosomes promote the efficient interaction between Cyclin B1 and the APC/C to ensure the timely degradation of Cyclin B1 and genomic stability.

Stock Inhalers: A Qualitative Data Analysis of Illinois Health Policy Trials and Triumphs.

BACKGROUND: Asthma reliever medication access is critical, especially in schools. Policies that "stock" reliever inhalers in schools provide failsafe medication access. This research aims to understand barriers and facilitators to Illinois stock inhaler policy implementation. METHODS: We conducted 18 semi-structured interviews in 2021-2022 with key school-based and non-school-based partners (school administrators, nurses, governmental agencies, and advocacy leaders). Through Atlas.ti, code frequencies compared (Fisher's exact test), and a thematic analysis performed. RESULTS: Four themes emerged: facilitators, barriers, program rationale, and process considerations. The common facilitators were "Finding a provider," having a "Champion," and "Funding". Barriers included "Not enough school nurses," "Pharmacy refusal to fill prescriptions," and "Feeling overwhelmed." All were supportive of the rationale for stock inhalers. Non-school-based informants (p < .01) were more likely to mention medication donations, while school staff reported having enough nurses as a facilitator (p < .01). School staff reported concerns about children with asthma not having their medication significantly more than other partners (p = .02). IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Our analysis revealed that school partners recognize the value of stock inhalers. Barrier mitigation to support the funding, prescription access and processing, and training are essential to success of stock inhaler programming. Multilevel collaborative efforts through coalitions could be a potential solution.

Cost-effectiveness analysis design for interventions to prevent children's oral disease.

Introduction: In 2015, the National Institute of Dental and Craniofacial Research (NIDCR) launched the Multidisciplinary Collaborative Research Consortium to Reduce Oral Health Disparities in Children, supporting four randomized trials testing strategies to improve preventive care. A Coordinating Center provides scientific expertise, data acquisition and quality assurance services, safety monitoring, and final analysis-ready datasets. This paper describes the trials' economic analysis strategies, placing these strategies within the broader context of contemporary economic analysis methods. Methods: The Coordinating Center established a Cost Collaborative Working Group to share information from the four trials about the components of their economic analyses. Study teams indicated data sources for their economic analysis using a set of structured tables. The Group meets regularly to share progress, discuss challenges, and coordinate analytic approaches. Results: All four trials will calculate incremental cost-effectiveness ratios; two will also conduct cost-utility analyses using proxy diseases to estimate health state utilities. Each trial will consider at least two perspectives. Key process measures include dental services provided to child participants. The non-preference-weighted Early Childhood Oral Health Impact Scale (ECOHIS) will measure oral health-related quality of life. All trials are measuring training, implementation, personnel and supervision, service, supplies, and equipment costs. Conclusions: Consistent with best practices, all four trials have integrated economic analysis during their planning stages. This effort is critical since poor quality or absence of essential data can limit retrospective analysis. Integrating economic analysis into oral health preventive intervention research can provide guidance to clinicians and practices, payers, and policymakers.

Examining Caregiver- and Family-Level Psychosocial Influences on Child Oral Health Behavioral Outcomes in Racially and Economically Minoritized Urban Families.

OBJECTIVES: Understanding the pathways linking caregiver- and family-level psychosocial factors and child oral health behaviors is critical for addressing oral health disparities. The current study examined the associations between caregiver psychosocial functioning and family chaos and child toothbrushing behaviors in children at high risk for poor oral health outcomes. METHODS: Data were drawn from the baseline wave of the CO-OP Chicago Cohort Study (U01DE030067), a longitudinal study on child/caregiver dyads exploring oral health behaviors and caries development in young children (N = 296 dyads; child mean age = 5.36, SD = 1.03; caregiver mean age = 33.8 years, SD = 6.70; caregiver race = 43% Black; caregiver ethnicity = 55% Latinx). The oral health behavioral outcomes included child toothbrushing frequency, child plaque levels, and caregiver assistance with child toothbrushing. The data included demographics; caregiver depression, anxiety, post-traumatic stress disorder (PTSD) symptoms, social functioning, social support, and resilience; and family-level household chaos. RESULTS: Multiple regression models indicated that greater household chaos was significantly related to lower caregiver assistance with child toothbrushing (p = 0.0075). Additionally, caregiver anxiety and PTSD symptoms as well as number of children in the home significantly predicted higher levels of household chaos (p < 0.01). Notably, 18% of caregivers reported clinically significant PTSD. The relationships between caregiver-level psychosocial factors and child oral health behaviors were not significant. CONCLUSIONS: The results suggest household chaos may play an important role in child oral health behaviors and highlight the importance of investigating family-level factors for understanding and addressing child oral health risk.

Leveraging Programmatic Collaboration for a Radiopharmaceutical Clinic.

Radiation oncologists, radiopharmacists, nuclear medicine physicians, and medical oncologists have seen a renewed clinical interest in radiopharmaceuticals for the curative or the palliative treatment of cancer. To allow for the discovery and the clinical advancement of targeted radiopharmaceuticals, these stakeholders have reformed their trial efforts and remodeled their facilities to accommodate the obligations of a program centered upon radioactive investigational drug products. Now considered informally as drugs and not beam radiotherapy, radiopharmaceuticals can be more easily studied in the traditional clinical trial enterprise ranging from phase 0-I to phase III studies. Resources and physical facilities allocated to radiopharmaceuticals have brought forth new logistics and patient experience for safe and satisfactory drug delivery. The clinical use of theranostic agents-that is, diagnostic and therapeutic radionuclide pairs-has accelerated radiopharmaceutical development.

Community-Based Organizations Leading Research Efforts: Preliminary Findings from the Chicagoland CEAL Program's COVID-19 Vaccine Uptake and Intention Survey.

BACKGROUND: To foster community engaged research in the communities most impacted by COVID-19, the National Institutes of Health (NIH) formed 21 teams of Community Engagement Alliance Against COVID-19 Disparities (CEAL). The national CEAL initiative developed a Common Survey to investigate attitudes and behaviors to the COVID-19 vaccine and clinical trials. This article describes survey implementation at the Chicagoland CEAL Program (CCP). METHODS: This community-based participatory research project was the result of a strong collaboration between academic institutions, and a community-based non-profit health equity-focused partner organization. The survey implementation was developed and refined with strong input from CHWs, participants, and staff in the partner organizations and institutions. Survey data were collected with Qualtrics, a web-based survey tool. RESULTS: Survey implementation resulted in data collection for 852 participants during the period 12/18/2021-02/18/2023. Excluding participants on the basis of missing data resulted in a sample of 690, 601 of which (87.10%) indicated that they had received at least one dose or intended to get vaccinated. Overall, 54 (7.83%) respondents reported that they had not received the vaccine and were not planning to. CONCLUSION: Hard to reach populations present two unique challenges in emerging infectious disease events. Reaching populations vulnerable to poor outcomes with vaccines was essential to addressing the COVID-19 pandemic. Additionally, learning about barriers and hesitancy toward vaccine uptake is difficult in these communities. CCP's partnership of five academic institutions, a community research center, and a community-based non-profit health equity-focused organization shows what is possible when traditional models of research and inquiry are reconsidered for community-based participatory research. Results shown here are drawn from a collaboratively designed and implemented survey, collected in person, with over 90% completion.

Identifying the function of the NMDA NR1 C2 subunit through its interaction with Magi-2 during inflammatory pain.

Much is understood about the structure and gating properties of NMDA receptors (NMDAR), but the function of the carboxy-terminal splice variant of the NR1 subunit, NR1 C2 has never been identified. By studying the scaffolding protein Magi-2 in animal models of inflammatory pain, we discovered how NR1 C2 protein is specifically regulated. We found that Magi-2 deficiency resulted in decreased pain behavior and a concomitant reduction in NR1 C2 protein. Magi-2 contains WW domains, domains typically found in ubiquitin ligases. We identified an atypical WW-binding domain within NR1 C2 which conferred susceptibility to Nedd4-1 ubiquitin-ligase dependent degradation. We used lipidated peptidomimetics derived from the NR1 C2 sequence and found that NR1 C2 protein levels and pain behavior can be pharmacologically targeted. The function of NR1 C2 is to give lability to a pool of NMDAR, important for pain signaling.

Association between sleep disorders and health care utilization in children with chronic medical conditions: a Medicaid claims data analysis.

STUDY OBJECTIVES: To examine the risk of increased health care utilization (HU) linked to individual sleep disorders in children with chronic medical conditions. METHODS: Medicaid claims data from a cohort of 16,325 children enrolled in the Coordinated Healthcare for Complex Kids (CHECK) project were used. Sleep disorders and chronic medical conditions were identified using International Classification of Diseases, Ninth, and 10th Revision, codes. Three HU groups were identified based on participants' prior hospitalizations and emergency department (ED) visits in the 12 months prior to enrollment: low (no hospitalization or ED visit), medium (1-2 hospitalizations or 1-3 ED visits), and high (≥ 3 hospitalizations or ≥ 4 ED visits). The odds of being in an increased HU group associated with specific sleep disorders after controlling for confounding factors were examined. RESULTS: Children with chronic medical conditions and any sleep disorder had nearly twice the odds (odds ratio = 1.83; 95% confidence interval: 1.67-2.01) of being in an increased HU group compared with those without a sleep disorder. The odds of being in the increased HU group varied among sleep disorders. Only sleep-disordered breathing (odds ratio = 1.51; 95% confidence interval : 1.17-1.95), insomnia (odds ratio = 1.46; 95% confidence interval : 1.06-2.02), and circadian rhythm sleep disorder (odds ratio = 2.45; 95% confidence interval : 1.07-5.64) increased those odds. Younger age and being White were also linked to increased HU. CONCLUSIONS: Sleep disorders are associated with increased risk of heightened HU (ED visits and/or hospitalizations) in children with chronic medical conditions. This risk varies by specific sleep disorders. These findings indicate the need for careful evaluation and management of sleep disorders in this high-risk cohort.

Delivering COVID-19 Vaccine via Trusted Social Services: Program Evaluation Results from the Chicagoland CEAL Program.

To describe the reach, implementation, and sustainability of COVID-19 vaccination programs delivered by social service community organizations. Five academic institutions in the Chicagoland CEAL (Community Engagement Alliance) program partnered with 17 community organizations from September 2021-April 2022. Interviews, community organizations program implementation tracking documents, and health department vaccination data were used to conduct the evaluation. A total of 269 events were held and 5,432 COVID-19 vaccines delivered from May 2021-April 2022. Strategies that worked best included offering vaccinations in community settings with flexible and reliable hours; pairing vaccinations with ongoing social services; giving community organizations flexibility to adjust programs; offering incentives; and vaccinating staff first. These strategies and partnership structures supported vaccine uptake, community organization alignment with their missions and communities' needs, and trust. Community organizations delivering social services are local community experts and trusted messengers. Pairing social service delivery with COVID-19 vaccination built individual and community agency. Giving COs creative control over program implementation enhanced trust and vaccine delivery. When given appropriate resources and control, community organizations can quickly deliver urgently needed health services in a public health crisis.

Understanding critical factors associated with integration of community health workers into health and hospital systems.

Community health worker (CHW) models have been shown to improve health behaviors and health outcomes and reduce cost, particularly among low-income underserved populations. Consequently, health systems are increasingly employing CHWs to provide health services in clinical environments. A growing body of the literature suggests that effective integration of CHWs within the healthcare system is important to achieve the desired outcomes, but the question of how to achieve effective integration is less clear. This study seeks to explore the integration of CHWs within a large state university health system to identify factors critical to the effective integration of CHWs into the clinical care environment. We conducted a qualitative descriptive multiple embedded case study of the University of Illinois at Chicago's Hospital and Health Science System (UI Health). The embedded subunits of analysis were teams within the UI Health System that currently employ CHWs to assist with the provision of clinical care or services to patients. Data were collected via semi-structured interviews and document review. In total, six sub-units were enrolled, and 17 interviews were conducted with CHWs (n = 9), and administrators or healthcare providers (n = 8). Fourteen factors related to effective CHW integration were identified and organized in four categories: individual, team, organization, and community. Findings suggest that in addition to commonly recognized elements of effective CHW models including training, supervision, and the presence of a champion, programs must consider the organizational context in which the program is positioned as well as the ways in which both CHWs and the organization engage with communities served. This research can serve as a roadmap for health systems that seek to integrate CHWs within healthcare services and can be used to promote best practice in CHW integration.

Adoption and Discontinuance of Innovation Packages: A Longitudinal Study of Transitions in COVID-19 Mitigation.

The past decades have seen growing interest and application of interventions targeting the change of multiple behaviors at once. We advance this work by using the diffusion of innovations theory (DOI) to consider constellations of behaviors as innovation packages: multiple innovations that are logically related, interdependent in their use or effects, and often promoted as a set (Rogers, 2003). In addition, we embraced DOI's focus on behavioral decisions as a continual process that can include adoption and discontinuance over time, especially as new innovations (e.g., COVID-19 vaccine) appear. To that end, we conducted a latent transition analysis of COVID-19 mitigation behaviors (N = 697; 97% received a COVID-19 vaccine) across three time points in the pandemic: initial outbreak; a secondary, record-breaking rise in cases; and after the CDC recommended that fully vaccinated adults could discontinue wearing masks. This analysis allowed us to identify latent classes based on shared behavioral patterns and transitions between classes over time. The results showed evidence of three possible packages: (a) a package of traditional, symptom-management behaviors (covering coughs and sneezes, staying home if ill, and seeking medical care), (b) a package of just-novel COVID-19 behaviors (wearing masks, keeping six feet apart, and avoiding mass gatherings), and (c) a package of all COVID-19 mitigation behaviors. Movement between classes exemplified adoption and discontinuance of different packages, as well as widespread discontinuance with the replacement innovation: COVID-19 vaccines. Additional analyses showed that increases in hope were associated with sustained and delayed adoption; decreases in social approval were associated with discontinuance. Future directions in theorizing around innovation packages are discussed.

Oral Health Behaviors for Young Low-Income Urban Children during the COVID-19 Pandemic: A Mixed Methods Analysis.

This research assessed oral health behaviors changes in urban families with young children during the stay-at-home period of the COVID-19 pandemic (Nov 2020-August 2021). Survey data on oral health behaviors were collected in homes at three points before COVID-19, and via phone during COVID-19. A subset of parents and key informants from clinics and social service agencies completed in-depth interviews via video/phone. Of the 387 parents invited, 254 completed surveys in English or Spanish (65.6%) during COVID-19. Fifteen key informant interviews (25 participants) and 21 family interviews were conducted. The mean child age was 4.3 years. Children identified as mainly Hispanic (57%) and Black race (38%). Parents reported increased child tooth brushing frequency during the pandemic. Family interviews highlighted changes in family routines that impacted oral health behaviors and eating patterns, suggesting less optimal brushing and nutrition. This was linked to changed home routines and social presentability. Key informants described major disruptions in oral health services, family fear, and stress. In conclusion, the stay-at-home period of the COVID-19 pandemic was a time of extreme routine change and stress for families. Oral health interventions that target family routines and social presentability are important for families during times of extreme crisis.

Coordinated Health Care Interventions for Childhood Asthma Gaps in Outcomes (CHICAGO) plan.

Background: Evidence-based strategies to improve outcomes in minority children with uncontrolled asthma discharged from the emergency department (ED) are needed. Objectives: This multicenter pragmatic clinical trial was designed to compare an ED-only intervention (decision support tool), an ED-only intervention and home visits by community health workers for 6 months (ED-plus-home), and enhanced usual care (UC). Methods: Children aged 5 to 11 years with uncontrolled asthma were enrolled. The change over 6 months in the Patient-Reported Outcomes Measurement Information System Asthma Impact Scale score in children and Satisfaction with Participation in Social Roles score in caregivers were the primary outcomes. The secondary outcomes included guideline-recommended ED discharge care and self-management. Results: Recruitment was significantly lower than expected (373 vs 640 expected). Of the 373 children (64% Black and 31% Latino children), only 63% completed the 6-month follow-up visit. In multivariable analyses that accounted for missing data, the adjusted odds ratios and 98% CIs for differences in Asthma Impact Scores or caregivers' Satisfaction with Participation in Social Roles scores were not significant. However, guideline-recommended ED discharge care was significantly improved in the intervention groups versus in the UC group, and self-management behaviors were significantly improved in the ED-plus-home group versus in the ED-only and UC groups. Conclusions: The ED-based interventions did not significantly improve the primary clinical outcomes, although the study was likely underpowered. Although guideline-recommended ED discharge care and self-management did improve, their effect on clinical outcomes needs further study.

What Chicago community organizations needed to implement COVID-19 interventions: lessons learned in 2021.

Introduction: As the COVID-19 pandemic placed a spotlight on the health inequities in the United States, this study aimed to determine the local programmatic needs of community organizations (CO) delivering COVID-19 interventions across Chicago. Methods: In the summer of 2021, the Chicagoland CEAL Program interviewed 34 COs that were providing education, testing, and/or vaccinations in communities experiencing poor COVID-19 outcomes. The interviews were analyzed thematically and organized around logistical challenges and funding/resource needs. Results: The COs routinely offered testing (50%) or vaccinations (74%), with most (56%) employing some programmatic evaluation. Programs utilizing trusted-messenger systems were deemed most effective, but resource-intensive. CO specific needs clustered around sustaining effective outreach strategies, better CO coordination, wanting comprehensive trainings, improving program evaluation, and promoting services and programs. Conclusion: The COs reached populations with low-vaccine confidence using trusted messengers to overcome mistrust. However, replenishment of the resources needed to sustain such strategies should be prioritized. Leveraging the Chicagoland CEAL Program to help negotiate community organizations' interorganizational coordination, create training programs, and provide evaluation expertise are deliverable supports that may bolster COVID-19 prevention. Policy implications: Achieving health justice requires that all institutions of power participate in meaningful community engagement, help build community capacity, and infuse health equity throughout all aspects of the research and program evaluation processes.

Trustworthiness, Not Trust: How Systemic Racism Impacts COVID-19 Vaccine Receipt.

To illuminate the forces of structural racism influencing COVID-19 vaccine receipt, we developed a conceptual model that recontextualizes trust and presents potential pathways to address structural racism. Our model emerged from Chicagoland CEAL, a partnership of community and academic experts collaborating to encourage COVID-19 vaccine uptake for communities of color. We concluded that systemic factors influenced by racism contribute to an overall lack of trustworthiness in vaccine-affiliated institutions. We highlight the need to recenter discussions of COVID-19 vaccination on our system's trustworthiness rather than mistrust and suggest using the model to test pathways to close racial gaps in COVID-19 vaccination.

Association between neighborhood disadvantage and children's oral health outcomes in urban families in the Chicago area.

Purpose: The prevalence of childhood caries in urban Chicago, compared with national and state data, indicates that neighborhood context influences oral health. Our objective was to delineate the influence of a child's neighborhood on oral health outcomes that are predictive of caries (toothbrushing frequency and plaque levels). Methods: Our study population represents urban, Medicaid-enrolled families in the metropolitan Chicago area. Data were obtained from a cohort of participants (child-parent dyads) who participated in the Coordinated Oral Health Promotion (CO-OP) trial at 12 months of study participation (N = 362). Oral health outcomes included toothbrushing frequency and plaque levels. Participants' neighborhood resource levels were measured by the Area Deprivation Index (ADI). Linear and logistic regression models were used to measure the influence of ADI on plaque scores and toothbrushing frequency, respectively. Results: Data from 362 child-parent dyads were analyzed. The mean child age was 33.6 months (SD 6.8). The majority of children were reported to brush at least twice daily (n = 228, 63%), but the mean plaque score was 1.9 (SD 0.7), classified as "poor." In covariate-adjusted analyses, ADI was not associated with brushing frequency (0.94, 95% CI 0.84-1.06). ADI was associated with plaque scores (0.05, 95% CI 0.01-0.09, p value = 0.007). Conclusions: Findings support the hypothesis that neighborhood-level factors influence children's plaque levels. Because excessive plaque places a child at high risk for cavities, we recommend the inclusion of neighborhood context in interventions and policies to reduce children's oral health disparities. Existing programs and clinics that serve disadvantaged communities are well-positioned to support caregivers of young children in maintaining recommended oral health behaviors.

Oral health behaviors for young low-income urban children during the COVID-19 pandemic: a mixed methods analysis.

This research assessed oral health behaviors changes in urban families with young children during the stay-at-home period of the COVID-19 pandemic. Survey data on oral health behaviors were collected in homes at three points over one year before COVID-19, and then via phone during COVID-19. Multivariate logistic regression was used to model tooth brushing frequency. A subset of parents completed in-depth interviews via video/phone that expanded on oral health and COVID-19. Key informant interviews via video/phone were also conducted with leadership from 20 clinics and social service agencies. Interview data were transcribed and coded, and themes were extracted. COVID-19 data collection went from Nov 2020 - August 2021. Of the 387 parents invited, 254 completed surveys in English or Spanish (65.6%) during COVID-19. Fifteen key informant (25 participants) and 21 parent interviews were conducted. The mean child age was approximately 4.3 years. Children identified as mainly Hispanic (57%) and Black race (38%). Parents reported increased child tooth brushing frequency during the pandemic. Parent interviews highlighted significant changes in family routines that impacted oral health behaviors and eating patterns, suggesting less optimal brushing and nutrition. This was linked to changed home routines and social presentability. Key informants described major disruptions in their oral health services and significant family fear and stress. In conclusion, the stay-at-home period of the COVID-19 pandemic was a time of extreme routine change and stress for families. Oral health interventions that target family routines and social presentability are important for families during times of extreme crisis.

Calibration and reliability testing of a novel asynchronous photographic plaque scoring system in young children.

OBJECTIVES: The Simplified Oral Hygiene Index for Maxillary Incisors (OHI-MIS) is a novel plaque scoring system adapted for young children. This study describes calibration training and testing used to establish the inter- and intra-rater reliability for OHI-MIS measured from clinical photographs. METHODS: Two raters from the Coordinated Oral Health Promotion Chicago (CO-OP) and one from the Behavioral EConomics for Oral health iNnovation (BEECON) randomized controlled trials (RCTs) underwent calibration with gold standard raters, followed by annual re-calibration. Raters from CO-OP also completed inter-rater reliability testing; all three raters completed intra-rater reliability testing rounds. Photographs were obtained from children aged 9-39 months. RESULTS: All three raters achieved greater than 0.77 Lin's Concordance Correlation (LCC) versus gold standard consensus during calibration. All three raters had LCC ≥0.83 at recalibration 1 year later. CO-OP trial raters scored 604 photos (151 sets of 4 photographs); mostly both raters were somewhat/very confident in their scoring (≥89%), describing the most photos as "clear" (90% and 81%). The CO-OP inter-rater LCC for total OHI-MIS score was 0.86, changing little when low quality or confidence photos were removed. All three raters demonstrated high intra-rater reliability (≥0.83). CONCLUSIONS: The OHI-MIS plaque scoring system on photos had good reliability within and between trials following protocol training and calibration. OHI-MIS provides a novel asynchronous plaque scoring system for use in young children. Non-clinicians in field or clinical settings can obtain photographs, offering new opportunities for research and clinical care.

The Effect of Neighborhood Disorganization on Care Engagement Among Children With Chronic Conditions Living in a Large Urban City.

Neighborhood context plays an important role in producing and reproducing current patterns of health disparity. In particular, neighborhood disorganization affects how people engage in health care. We examined the effect of living in highly disorganized neighborhoods on care engagement, using data from the Coordinated Healthcare for Complex Kids (CHECK) program, which is a care delivery model for children with chronic conditions on Medicaid in Chicago. We retrieved demographic data from the US Census Bureau and crime data from the Chicago Police Department to estimate neighborhood-level social disorganization for the CHECK enrollees. A total of 6458 children enrolled in the CHECK between 2014 and 2017 were included in the analysis. Families living in the most disorganized neighborhoods, compared with areas with lower levels of disorganization, were less likely to engage in CHECK. Black families were less likely than Hispanic families to be engaged in the CHECK program. We discuss potential mechanisms through which disorganization affects care engagement. Understanding neighborhood context, including social disorganization, is key to developing more effective comprehensive care models.

Community health worker intervention to improve tooth brushing in young children: Results from a cluster randomized controlled trial.

OBJECTIVES: Coordinated Oral health Promotion (CO-OP) Chicago is a cluster randomized controlled trial testing the efficacy of a community health worker (CHW) intervention to improve tooth brushing in low-income children. METHODS: Four hundred twenty children under 3 years old (mean 21.5 months) were recruited from 20 sites in or near Chicago, IL. Children were identified mainly as Black race (41.9%) or Hispanic ethnicity (53.8%) and most (85.2%) had Medicaid. Intervention families were offered four CHW home visits over 1 year. Brushing frequency was self-reported. Plaque score was determined from images collected in homes using disclosing solution. Analyses used GEE logistic models with variable selection at p < .05. RESULTS: At enrolment, 45.0% of families reported twice a day or more child brushing frequency, and child plaque scores were poor (mean of 1.9, SD: 0.6). Data were obtained from 87.1% of children at 6 months and 86.2% at 12 months. In the CHW intervention arm (10 sites, N = 211), 23.7% received 4 visits, 12.8% 3 visits, 21.3% 2 visits, 23.2% 1 visit and 19% no visits from CHWs. No intervention effect was seen for brushing frequency or plaque score. Child brushing frequency improvement over time was associated with a range of child and caregiver factors. The only factor associated with a change in plaque score over time was parent involvement in brushing. CONCLUSIONS: Oral-health-specific CHW services were not associated with improved brushing behaviours in these young children. However, caregiver involvement with brushing supported more quality brushing. More robust interventions are needed to support families during this critical developmental period.
