RESUMO
Importance: Influenza virus infections declined globally during the COVID-19 pandemic. Loss of natural immunity from lower rates of influenza infection and documented antigenic changes in circulating viruses may have resulted in increased susceptibility to influenza virus infection during the 2021-2022 influenza season. Objective: To compare the risk of influenza virus infection among household contacts of patients with influenza during the 2021-2022 influenza season with risk of influenza virus infection among household contacts during influenza seasons before the COVID-19 pandemic in the US. Design, Setting, and Participants: This prospective study of influenza transmission enrolled households in 2 states before the COVID-19 pandemic (2017-2020) and in 4 US states during the 2021-2022 influenza season. Primary cases were individuals with the earliest laboratory-confirmed influenza A(H3N2) virus infection in a household. Household contacts were people living with the primary cases who self-collected nasal swabs daily for influenza molecular testing and completed symptom diaries daily for 5 to 10 days after enrollment. Exposures: Household contacts living with a primary case. Main Outcomes and Measures: Relative risk of laboratory-confirmed influenza A(H3N2) virus infection in household contacts during the 2021-2022 season compared with prepandemic seasons. Risk estimates were adjusted for age, vaccination status, frequency of interaction with the primary case, and household density. Subgroup analyses by age, vaccination status, and frequency of interaction with the primary case were also conducted. Results: During the prepandemic seasons, 152 primary cases (median age, 13 years; 3.9% Black; 52.0% female) and 353 household contacts (median age, 33 years; 2.8% Black; 54.1% female) were included and during the 2021-2022 influenza season, 84 primary cases (median age, 10 years; 13.1% Black; 52.4% female) and 186 household contacts (median age, 28.5 years; 14.0% Black; 63.4% female) were included in the analysis. During the prepandemic influenza seasons, 20.1% (71/353) of household contacts were infected with influenza A(H3N2) viruses compared with 50.0% (93/186) of household contacts in 2021-2022. The adjusted relative risk of A(H3N2) virus infection in 2021-2022 was 2.31 (95% CI, 1.86-2.86) compared with prepandemic seasons. Conclusions and Relevance: Among cohorts in 5 US states, there was a significantly increased risk of household transmission of influenza A(H3N2) in 2021-2022 compared with prepandemic seasons. Additional research is needed to understand reasons for this association.

Accurate estimates of the total burden of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are needed to inform policy, planning, and response. We sought to quantify SARS-CoV-2 cases, hospitalizations, and deaths by age in Michigan. Coronavirus disease 2019 cases reported to the Michigan Disease Surveillance System were multiplied by age and time-specific adjustment factors to correct for under-detection. Adjustment factors were estimated in a model fit to incidence data and seroprevalence estimates. Age-specific incidence of SARS-CoV-2 hospitalization, death, vaccination, and variant proportions were estimated from publicly available data. We estimated substantial under-detection of infection that varied by age and time. Accounting for under-detection, we estimate the cumulative incidence of infection in Michigan reached 75% by mid-November 2021, and over 87% of Michigan residents were estimated to have had ≥1 vaccination dose and/or previous infection. Comparing pandemic waves, the relative burden among children increased over time. In general, the proportion of cases who were hospitalized or who died decreased over time. Our results highlight the ongoing risk of periods of high SARS-CoV-2 incidence despite widespread prior infection and vaccination. This underscores the need for long-term planning for surveillance, vaccination, and other mitigation measures amidst continued response to the acute pandemic.

DNA methylation is involved in numerous biological processes and is deregulated in human diseases. The modulation of the activity of the enzymes and proteins in charge of DNA methylation, for example, DNA methyltransferases (DNMTs), can represent a powerful strategy to alter DNA methylation patterns and restore biological processes that are aberrant in diseases. In this chapter, we present examples of inhibitors of DNMTs (DNMTi). We review their fields of application either as therapeutic molecules, for example, in cancers, cardiovascular, neurological, and infectious diseases or as bioengineering tools. Finally, novel strategies to target DNA methylation and overcome the limits of single DNMT inhibitors will be described. These strategies consist in either targeting the methyl group reader proteins rather than targeting directly DNMTs or to combine within the same molecule a DNMT inhibitor with an additional active moiety, e.g., HDAC inhibitor, to improve efficacy and lower secondary effect of such drug.

PURPOSE: Controversy exists among head and neck surgical specialties regarding management of Langerhan's Cell Histiocytosis (LCH). The purpose of this study was to evaluate diagnosis, management, and treatment outcomes in children with LCH of the head and neck. METHODS: This is a retrospective cohort study of children with LCH of the head and neck who presented to Children's Healthcare of Atlanta hospital from 2009 to 2021. The independent variables were demographic information, lesion locations, clinical presentation, radiographic findings, diagnostic workup, treatment, and length of follow-up. The patients were grouped based on these variables. The outcome variable was disease reactivation. Descriptive statistics were calculated. RESULTS: There were 3 presentations of LCH of the head and neck. Group 1 presented as a lesion in 1 system without CNS risk (SS-). There were 24 patients with an average age of 10 years. Lesions were located in calvaria and/or mandible. Majority of the patients were treated with only debridement. Two of the patients experienced reactivation. Group 2 presented as a lesion in 1 system with CNS risk (SS+). There were 30 patients with an average age of 6 years. Common locations were temporal bone and/or orbit. These patients present with recurrent ear infections and ptosis. Majority of the patients were treated with chemotherapy (n = 28). One patient had disease reactivation. Group 3 presented with multisystem involvement. There were 13 patients with an average age of 2 years. LCH was found in skin and the lymphatic system. Imaging demonstrated extracranial organ involvement. All of them were treated with chemotherapy. There was 40% reactivation of LCH. CONCLUSIONS: Treatment of LCH depends on presentation. SS- subgroup can be adequately treated via surgical debridement. SS+ and multisystem groups benefit from an early disease diagnosis and require chemotherapy.

OBJECTIVE: To test the hypothesis that newborn infants cared for in hospitals with greater utilization of neonatal intensive care experienced fewer postdischarge adverse events. STUDY DESIGN: We developed 3 retrospective population-based cohorts of Texas Medicaid insured singletons born in 2010-2014 (very low birth weight [VLBW n = 11 139], late preterm [n = 57 509], and non-preterm [n = 664 447]) who received care in higher volume hospitals with level III/IV neonatal intensive care units (NICUs). Measures of NICU care were hospital-level risk adjusted NICU admission rates, special care days (days of nonroutine care) per infant, and the percent of intensive (highest billable care code) special care days. The units of analysis were hospitals (n = 80) and the primary outcome was an adverse event, (defined as admission, emergency department visit, or death) within 30 days postdischarge. RESULTS: Higher use of NICU care at a hospital level was not associated with lower postdischarge 30-day adverse event. Infants cared for in hospitals with above vs below median special care day rates experienced slightly higher postdischarge adverse event per 100 infants (VLBW: 14.01 [95% CI 12.74-15.27] vs 11.84 [10.52-13.16], P < .05; late preterm: 7.33 [6.68-7.97] vs 6.28 [5.87-6.69], P < .01; non-preterm: 4.47 [4.17-4.76] vs 3.97 [3.75-4.18], P < .01). Weak positive associations (Pearson correlations of 0.31-0.37, P < .01) were observed for adverse event with special care days; in no instance was a negative association observed between NICU utilization and adverse event. CONCLUSION: Higher utilization of NICU care was not associated with lower rates of short-term events suggesting that there may be opportunities to safely decrease admission rates and length of NICU stays.

BACKGROUND: Despite increasing interest in joint research priority-setting, few studies engage end-user groups in setting research priorities at the intersection of the healthcare and management disciplines. With health systems increasingly establishing performance management programmes to account for and incentivize performance, it is important to conduct research that is actionable by the end-users involved with or impacted by these programmes. The aim of this study was to co-design a research agenda on healthcare performance management with and for end-users in a specific jurisdictional and policy context. METHODS: We undertook a rapid review of the literature on healthcare performance management (n = 115) and conducted end-user interviews (n = 156) that included a quantitative ranking exercise to prioritize five directions for future research. The quantitative rankings were analysed using four methods: mean, median, frequency ranked first or second, and frequency ranked fifth. The interview transcripts were coded inductively and analysed thematically to identify common patterns across participant responses. RESULTS: Seventy-three individual and group interviews were conducted with 156 end-users representing diverse end-user groups, including administrators, clinicians and patients, among others. End-user groups prioritized different research directions based on their experiences and information needs. Despite this variation, the research direction on motivating performance improvement had the highest overall mean ranking and was most often ranked first or second and least often ranked fifth. The research direction was modified based on end-user feedback to include an explicit behaviour change lens and stronger consideration for the influence of context. CONCLUSIONS: Joint research priority-setting resulted in a practice-driven research agenda capable of generating results to inform policy and management practice in healthcare as well as contribute to the literature. The results suggest that end-users are keen to open the "black box" of performance management to explore more nuanced questions beyond "does performance management work?" End-users want to know how, when and why performance management contributes to behaviour change (or fails to) among front-line care providers.

Clostridium difficile infection (CDI) recurs in â¼20% of patients. Prior studies indicated that antibody responses directed against the C. difficile toxins A and B were potentially associated with lower risk of recurrent CDI. Here we tested the hypothesis that circulating anti-toxin IgG antibody levels associate with reduced risk of recurrent CDI. A cohort study with prospective enrollment and retrospective data abstraction examined antibody levels in 275 adult patients at the University of Michigan with CDI. We developed an enzyme linked immunosorbent assay to detect IgG antibodies against toxin A and toxin B in sera obtained at the time of diagnosis. Logistic regression examined the relationship between antibody levels and recurrence, and sensitivity tests evaluated for follow-up and survivor biases, history of CDI, and PCR ribotype. Follow-up data were available for 174 subjects, of whom 36 (20.7%) had recurrence. Comparing antibody levels vs. recurrence and CDI history, anti-toxin A levels were similar, while anti-toxin B levels had a greater range of values. In unadjusted analysis, detection of anti-toxin A antibodies, but not anti-toxin B antibodies, associated with an increased risk of recurrence (OR 2.71 [1.06, 8.37], P = .053). Adjusting for confounders weakened this association. The results were the same in sensitivity analyses. We observed a borderline increased risk of recurrence in patients positive for anti-toxin A antibodies, and sensitivity analyses showed this was not simply a reflection of prior exposure status. Future studies are needed to assess how neutralizing antibody or levels after treatment associate with recurrence.

The length of the cancer diagnostic interval can affect a patient's survival and psychosocial well-being. Ontario Diagnostic Assessment Units (DAUs) were designed to expedite the diagnostic process through coordinated care. We examined the effect of DAUs on the diagnostic interval among female patients with symptomatic breast cancer in Ontario using the Ontario Cancer Registry linked to administrative healthcare data. The diagnostic interval was defined as the time from patients' first referral or test to the cancer diagnosis. DAU use was determined based on the hospital where the breast biopsy/surgery was performed. Multivariable quantile regression and logistic regression analyses adjusted for possible confounders. Forty-seven per cent of patients were diagnosed in a DAU and 53% in usual care (UC). DAUs achieved the Canadian timeliness targets more often than UC (71.7% vs. 58.1%, respectively). DAU use was associated with a 10-day (95% CI: 7.8-11.9) reduction in the median diagnostic interval. This effect increased to 19 days for patients at the 75th percentile and 22 days for those at the 90th percentile of the diagnostic interval distribution. Use of an Ontario DAU is associated with a shorter time to diagnosis in patients with symptomatic breast cancer, especially for those who would otherwise wait the longest.

Surveys and interviews were undertaken in Ontario, Canada, with healthcare staff, patients, caregivers and family members to evaluate the adoption and effectiveness of the experience-based co-design (EBCD) approach. EBCD combines patient and staff experiences to identify opportunities for healthcare improvement. Participants reported that EBCD was an effective form of improving experience. Implementation barriers included time, human resources and funding. Suggestions for increased EBCD utilization included funding, training, promotion of success stories, leadership and greater participant involvement. EBCD can be an effective method of identifying and transforming how healthcare services are delivered to improve the patient, caregiver and family experience.

OBJECTIVE: To examine provincial and regional differences in FPs' direct access to cancer diagnostic investigations and advice from other specialists regarding investigations and referrals, and to explore FPs' perceptions about wait times for diagnostic investigations and receipt of results. DESIGN: A cross-sectional, online survey. SETTING: British Columbia, Manitoba, and Ontario. PARTICIPANTS: A sample of FPs from participating provinces. MAIN OUTCOME MEASURES: Direct FP access to various diagnostic investigations and advice from other specialists regarding investigations and referrals; FPs' perceptions about wait times for diagnostic investigations ordered directly; and FPs' perceptions about wait times for results. RESULTS: A total of 1054 surveys were completed by FPs from British Columbia (n = 229), Manitoba (n = 228), and Ontario (n = 597). Distance from a cancer centre was not significantly associated with direct access to or wait times for diagnostic investigations for most of the investigations studied; however, provincial differences were observed. Family physicians in Manitoba and British Columbia were 30% to 45% less likely to report having direct access to endoscopy and some imaging investigations compared with FPs in Ontario. Family physicians in Manitoba and British Columbia were also at increased odds of waiting longer than 12 weeks for endoscopy investigations and longer than 4 weeks for imaging investigations compared with FPs in Ontario. Most FPs reported wait times of less than 2 weeks for imaging results; however, the proportion of FPs who waited longer than 2 weeks for colonoscopy results ranged from 15% in Ontario to 96% in British Columbia. CONCLUSION: Given the disparities observed among provinces, there is an opportunity for provinces to learn from one another to improve direct access to and shorten wait times for diagnostic investigations. This in turn has the potential to shorten the primary care interval for cancer diagnostic assessment.

BACKGROUND: Prolonged SARS-CoV-2 infections in people who are immunocompromised might predict or source the emergence of highly mutated variants. The types of immunosuppression placing patients at highest risk for prolonged infection have not been systematically investigated. We aimed to assess risk factors for prolonged SARS-CoV-2 infection and associated intrahost evolution. METHODS: In this multicentre, prospective analysis, participants were enrolled at five US medical centres. Eligible patients were aged 18 years or older, were SARS-CoV-2-positive in the previous 14 days, and had a moderately or severely immunocompromising condition or treatment. Nasal specimens were tested by real-time RT-PCR every 2-4 weeks until negative in consecutive specimens. Positive specimens underwent viral culture and whole genome sequencing. A Cox proportional hazards model was used to assess factors associated with duration of infection. FINDINGS: From April 11, 2022, to Oct 1, 2022, 156 patients began the enrolment process, of whom 150 were enrolled and included in the analyses. Participants had B-cell malignancy or anti-B-cell therapy (n=18), solid organ transplantation or haematopoietic stem-cell transplantation (HSCT; n=59), AIDS (n=5), non-B-cell malignancy (n=23), and autoimmune or autoinflammatory conditions (n=45). 38 (25%) participants were real-time RT-PCR-positive and 12 (8%) were culture-positive 21 days or longer after initial SARS-CoV-2 detection or illness onset. Compared with the group with autoimmune or autoinflammatory conditions, patients with B-cell dysfunction (adjusted hazard ratio 0·32 [95% CI 0·15-0·64]), solid organ transplantation or HSCT (0·60 [0·38-0·94]), and AIDS (0·28 [0·08-1·00]) had longer duration of infection, defined as time to last positive real-time RT-PCR test. There was no significant difference in the non-B-cell malignancy group (0·58 [0·31-1·09]). Consensus de novo spike mutations were identified in five individuals who were real-time RT-PCR-positive longer than 56 days; 14 (61%) of 23 were in the receptor-binding domain. Mutations shared by multiple individuals were rare (<5%) in global circulation. INTERPRETATION: In this cohort, prolonged replication-competent omicron SARS-CoV-2 infections were uncommon. Within-host evolutionary rates were similar across patients, but individuals with infections lasting longer than 56 days accumulated spike mutations, which were distinct from those seen globally. Populations at high risk should be targeted for repeated testing and treatment and monitored for the emergence of antiviral resistance. FUNDING: US Centers for Disease Control and Prevention.

Patients with colorectal cancer (CRC) face a number of challenges leading up to diagnosis; however, research is limited regarding their specific needs during the pre-diagnosis period. A multicenter cross-sectional survey was conducted to elicit information about the CRC experience during the pre-diagnosis phase. Across the three sites, 104 eligible patients were approached, and 82 patients completed the survey, for a total response rate of 78.9%. The needs most identified by participants during the pre-diagnosis period were informational (31.6%) and emotional (20.3%) needs; social needs were rated as the least important need for these patients (7%). The majority (84.0%) reported that these needs were met. Participants reported feeling shocked or overwhelmed on learning of their diagnosis (57.1%) and high levels of anxiety during this time (40.0%). The majority (77.9%) of participants reported that they were not directed to any resources to help address their anxiety. Informational and emotional needs are identified as the most important needs during the pre-diagnosis phase, and for most these needs are being met; however, some participants are experiencing high levels of anxiety without access to appropriate resources. Further work is required to understand the optimal mechanisms to address identified needs during this pre-diagnosis period and to assess the potential benefits and costs of addressing these needs.

BACKGROUND: Older adults (people aged 65 years and older) face many difficult decisions. Patient decision aids (PtDAs) can help them and their families make informed value-congruent decisions. Some PtDAs have been developed for the home care context, but little is known about scaling them for use with older adults in a different culture. OBJECTIVE: This study aims to (1) assess the scalability of existing PtDAs for older adults in the home care context; (2) prioritize those that best match the decisional needs of older adults in home care; and (3) culturally adapt the prioritized PtDAs so they can be scaled successfully to the Quebec health care system. METHODS: This multimethod study includes 3 phases. All phases will be overseen by a steering committee of older adults, caregivers, health professionals, decision makers, community organization representatives, and researchers with the needed expertise. In phase 1, we will use the Innovation Scalability Self-administered Questionnaire, a validated scalability self-assessment tool, to assess the scalability of 33 PtDAs previously identified in a systematic review. Based on their scalability, their quality (based on the International Patient Decision Aids Standards), and the importance of the decision point, we will retain approximately a third of these. In phase 2, we will conduct a 2-round web-based Delphi to prioritize the PtDAs selected in phase 1. Using a snowball recruitment strategy, we aim to recruit 60 Delphi participants in the province of Quebec, including older adults, caregivers, health professionals, decision makers involved in home care services, and PtDA experts. In the first round, we will ask participants to rate the importance of several PtDA decision points according to various criteria such as prevalence and difficulty on a 5-point Likert scale (1=not important to 5=very important). Approximately 6 of the highest-rated PtDAs will be retained for presentation in the second round, and we will select up to 3 PtDAs judged as having the highest priority for cultural adaptation. In phase 3, using the Chenel framework and user-centered design methods, we will update and adapt the PtDAs to the Quebec health care system and integrate these PtDAs into an interprofessional shared decision-making training program for home care teams. The adapted PtDAs will respect the International Patient Decision Aids Standards criteria. RESULTS: This study was funded in March 2022 by the Canadian Institutes of Health Research. Data collection for the web-based Delphi began in October 2023. Results are expected to be published in May 2024. CONCLUSIONS: This project will provide relevant and culturally appropriate decision support tools for older adults making difficult decisions and their home care teams that will be ready for scaling across the province of Quebec.

RESUMO
Background: Prolonged SARS-CoV-2 infections in immunocompromised hosts may predict or source the emergence of highly mutated variants. The types of immunosuppression placing patients at highest risk for prolonged infection and associated intrahost viral evolution remain unclear. Methods: Adults aged ≥18 years were enrolled at 5 hospitals and followed from 4/11/2022 - 2/1/2023. Eligible patients were SARS-CoV-2-positive in the previous 14 days and had a moderate or severely immunocompromising condition or treatment. Nasal specimens were tested by rRT-PCR every 2-4 weeks until negative in consecutive specimens. Positive specimens underwent viral culture and whole genome sequencing. A Cox proportional hazards model was used to assess factors associated with duration of infection. Results: We enrolled 150 patients with: B cell malignancy or anti-B cell therapy (n=18), solid organ or hematopoietic stem cell transplant (SOT/HSCT) (n=59), AIDS (n=5), non-B cell malignancy (n=23), and autoimmune/autoinflammatory conditions (n=45). Thirty-eight (25%) were rRT-PCR-positive and 12 (8%) were culture-positive ≥21 days after initial SARS-CoV-2 detection or illness onset. Patients with B cell dysfunction had longer duration of rRT-PCR-positivity compared to those with autoimmune/autoinflammatory conditions (aHR 0.32, 95% CI 0.15-0.64). Consensus (>50% frequency) spike mutations were identified in 5 individuals who were rRT-PCR-positive >56 days; 61% were in the receptor-binding domain (RBD). Mutations shared by multiple individuals were rare (<5%) in global circulation. Conclusions: In this cohort, prolonged replication-competent Omicron SARS-CoV-2 infections were uncommon. Within-host evolutionary rates were similar across patients, but individuals with infections lasting >56 days accumulated spike mutations, which were distinct from those seen globally.
RESUMO
OBJECTIVE: In late 2006, Cancer Care Ontario launched a quality improvement initiative to implement routine screening with the Edmonton Symptom Assessment System (ESAS) for cancer patients seen in fourteen Regional Cancer Centres throughout the province. METHODS: A central team: created a provincial project plan and management and evaluation framework; developed common tools and provided expert coaching and guidance, provincial data analysis, progress reporting and program evaluation. Regional Steering Committees and Improvement teams were accountable for planning and coordination within each region and supported by a funded Regional Improvement Coordinator. A hybrid model for quality improvement facilitated process improvements and uptake of screening. RESULTS: Challenges to implementation included: lack of consensus on the chosen screening tool, lack of guidance for assessment or management of high scores, concern of inadequate time or resources to address issues identified by the screening, data entry was labour intensive, resistance to change and challenges to the traditional care model. Essential components for success were: centralized project management, a person dedicated to implementation of the project locally, clinical champions, clearly identified aims, monthly regional data reporting and implementation of quality improvement methodologies with expectations for performance. To achieve screening aims many centres engaged all members of the team, examined the roles of the different members and reorganized workflow and responsibilities and changed booking times. In March 2010, approximately 25,000 ESAS's were completed in the regional cancer centres across Ontario, with 60% of lung cancer patients and almost 40% of all other cancer patients who visited the Regional Cancer Centres screened. CONCLUSION: Routine physical and psychological distress screening is possible within regional cancer centres. Although considerable effort and investment is required, it is worthwhile as it helps create a culture that is more patient-centered.

Traumatic brain injury often results in physical, behavioral, and cognitive impairments perceived by health care practitioners to limit or exclude clients' full participation in treatment decision making. We used qualitative methods to evaluate the short- and long-term impact of "After the Crash: A Play About Brain Injury," a research-based drama designed to teach client-centered care principles to brain injury rehabilitation staff. We conducted interviews and observations with staff of two inpatient neurorehabilitation units in Ontario, Canada. Findings demonstrate the effectiveness of the play in influencing practice through the avoidance of medical jargon to improve clients' understanding and participation in treatment; newfound appreciation for clients' needs for emotional expression and sexual intimacy; increased involvement of family caregivers; and avoidance of staff discussions as if clients were unaware. These findings suggest that research-based drama can effect reflexivity, empathy, and practice change to facilitate a client-centered culture of practice in brain injury rehabilitation.

Patients with lung cancer have numerous and varying needs spanning across the cancer trajectory; however, only limited research has focused specifically on the pre-diagnosis phase. A multicentre cross-sectional survey was conducted to explore the experience of lung cancer patients during the pre-diagnosis phase. High levels of anxiety were reported by many participants (45.6 %). Informational (32.1 %), and emotional (24.1 %) needs were reported as most important; the majority (89.0 %) reported these needs were met. Most participants sought information throughout, with many (38.6 %) rating their oncology health care providers to be the best source of information. The majority (70.0 %) reported that they were not directed to any resources to help address their anxiety. During pre-diagnosis, informational and emotional needs appear most important, and for the majority, these were reportedly met. Although many experienced high levels of anxiety, few were directed to resources to address it.

BACKGROUND: Black and Hispanic children with B-acute lymphoblastic leukemia (B-ALL) experience worse outcomes compared with their non-Hispanic white (NHW) counterparts. Immune-based approaches have begun to transform the therapeutic landscape in children with B-ALL. Recent studies identified several alterations in both innate and adaptive immune cells in children with B-ALL that may impact disease risk and outcome. However, the impact of racial/ethnic background on immune microenvironment is less studied, as children of minorities background have to date been severely under-represented in such studies. METHODS: We performed high-dimensional analysis of bone marrow from 85 children with newly diagnosed B-ALL (Hispanic=29, black=18, NHW=38) using mass cytometry with 40 and 38-marker panels. RESULTS: Race/ethnicity-associated differences were most prominent in the innate immune compartment. Hispanic patients had significantly increased proportion of distinct mature CD57 +T-bet+DR+ NK cells compared with other cohorts. These differences were most apparent within standard risk (SR) patients with Hispanic SR patients having greater numbers of CD57 +NK cells compared with other cohorts (43% vs 26% p=0.0049). Hispanic and Black children also had distinct alterations in myeloid cells, with a significant increase in a population of non-classical activated HLA-DR +CD16+myeloid cells, previously implicated in disease progression, compared with NHW counterparts. Racial background also correlated with altered expression of inhibitory checkpoint PD-L1 on myeloid cells. CONCLUSION: There are surprisingly substantial race/ethnicity-based differences in innate immune cells of children with newly diagnosed B-ALL. These differences urge the need to enhance accrual of children from minorities background in immunetherapy trials and may impact their outcome following such therapy.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has had high incidence rates at institutions of higher education (IHE) in the United States, but the transmission dynamics in these settings are poorly understood. It remains unclear to what extent IHE-associated outbreaks have contributed to transmission in nearby communities. METHODS: We implemented high-density prospective genomic surveillance to investigate these dynamics at the University of Michigan and the surrounding community during the Fall 2020 semester (August 16-November 24). We sequenced complete severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomes from 1659 individuals, including 468 students, representing 20% of cases in students and 25% of total cases in Washtenaw County over the study interval. RESULTS: Phylogenetic analysis identifiedâ >200 introductions into the student population, most of which were not related to other student cases. There were 2 prolonged student transmission clusters, of 115 and 73 individuals, that spanned multiple on-campus residences. Remarkably, <5% of nonstudent genomes were descended from student clusters, and viral descendants of student cases were rare during a subsequent wave of infections in the community. CONCLUSIONS: The largest outbreaks among students at the University of Michigan did not significantly contribute to the rise in community cases in Fall 2020. These results provide valuable insights into SARS-CoV-2 transmission dynamics at the regional level.
RESUMO
BACKGROUND: Patient and family advisors (PFAs) contributed to the development of the Ontario Cancer Plan IV (OCP IV), a 4-year strategic plan for Ontario, Canada's cancer system produced by Cancer Care Ontario. OBJECTIVE: To understand the barriers and facilitators PFAs experience when they are engaged in health-care system planning and provide recommendations for future engagement. METHOD: Patient and family advisors who had an ongoing involvement in the development of the OCP IV were invited to take part in an interview. Qualitative data were analyzed for emergent themes and recommendations were generated. RESULTS: Key emergent themes highlighted necessary elements for effective engagement of PFAs. These included rapport (feeling valued, included as an equal and having supportive interpersonal relationships), communication (clarity and transparency, shared language and understanding, feeling heard, and effective teleconferencing), and leadership (from PFAs and staff). Recommendations for optimizing PFA engagement in health-care system planning were generated. CONCLUSION: Patient and family advisors can be effectively engaged in system-level strategic planning by building reciprocal rapport, effective communication, and strong leadership. Notably, developing "systems literacy" in PFAs is key to ensuring the voices of patients and their families are heard and reflected in health-care system plans.
