INTRODUCTION: Preliminary data suggest that an encapsulated balloon (EsoCheck), coupled with a 2 methylated DNA biomarker panel (EsoGuard), detects Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) with high accuracy. The initial assay requires sample freezing upon collection. The purpose of this study was to assess a next-generation EsoCheck sampling device and EsoGuard assay in a much-enlarged multicenter study clinically enhanced by using a Clinical Laboratory Improvement Amendments of 1988-compliant assay and samples maintained at room temperature. METHODS: Cases with nondysplastic BE (NDBE), dysplastic BE (indefinite for dysplasia, low-grade dysplasia, high-grade dysplasia), EAC, junctional adenocarcinoma, plus endoscopy controls without esophageal intestinal metaplasia, were prospectively enrolled. Medical assistants at 6 institutions delivered the encapsulated balloon per orally with inflation in the stomach. The inflated balloon sampled the distal 5 cm of the esophagus and then was deflated and retracted into the capsule, preventing sample contamination. EsoGuard bisulfite sequencing assayed levels of methylated vimentin and methylated cyclin A1. RESULTS: A total of 243 evaluable patients—88 cases (median age 68 years, 78% men, 92% White) and 155 controls (median age 57 years, 41% men, 88% White)—underwent adequate EsoCheck sampling. The mean procedural time was approximately 3 minutes. Cases included 31 with NDBE, 16 with indefinite for dysplasia/low-grade dysplasia, 23 with high-grade dysplasia, and 18 with EAC/junctional adenocarcinoma. Thirty-seven NDBE and dysplastic BE cases (53%) were short-segment BE (<3 cm). Overall sensitivity was 85% (95% confidence interval 0.78–0.93) and specificity was 85% (95% confidence interval 0.79–0.90). Sensitivity for NDBE was 84%. EsoCheck/EsoGuard detected 100% of cancers (n = 18). DISCUSSION: EsoCheck/EsoGuard demonstrated high sensitivity and specificity in detecting BE and BE-related neoplasia.

Abstract Black men hold the highest prostate cancer burden among all ethnicities; thus, there is an urgent need for research to inform the development and implementation of a culturally tailored intervention to reduce disparities and improve outcomes. In response, the Inclusive Cancer Care Research Equity (iCCaRE) Consortium was created to advance health equity and reduce disparities in prostate cancer. Addressing the unique needs of Black men require a genuine bidirectional relationship between scientist and the community. In the Black community, faith-based organizations are respected institutions advocating for health equity and justice. Given their vital role as community health gatekeepers, the iCCaRE Consortium partners with faith-based organizations. Rooted in community engaged research (CER), we conducted an environmental scan through stakeholder meetings to discuss the prevailing challenges and opportunities to meet the needs of the Black community along the prostate cancer care continuum. iCCaRE investigators including Partnership Engagement Services (PES) core partnered with faith-based organizations to ensure and advance community responsive cancer prevention. Together, with our faith-based leaders (N=18), we identified gaps including issues associated with the care continuum from screening to diagnosis and from treatment to survivorship; disparities according to health coverage and social determinants of health, and best practices to assist patients including care coordination, patient navigation, digital innovations, and programs offered by patient advocacy organizations. In response to the needs of the community and the strengths of faith-based organization, we prioritized our initial focus on increasing community prostate cancer literacy and activation using co-design educational infographics for both traditional and technology-based communication platforms. The infographics provided evidence-based facts about prostate cancer burden in the Black community; and using a call to action approach, we emphasized the importance of taking action for life saving screening, prevention and healthy lifestyle. Taking action in prostate cancer symptom recognition, survivorship care, and quality care. Also, co-designed infographics were created for clinical studies and biospecimen awareness and participation and the importance of advocacy and equitable care. Another component incorporated face to face trainings and presentations to enhance their knowledge of cancer screening tools, epidemiology of prostate cancer, and pathways to care. This presentation highlighted the first step towards community based intervention development, implementation and dissemination towards equity and justice for prostate cancer prevention and patient/survivor improvements for Black men.

Background. Pancreas transplant biopsy practices for the diagnosis of rejection or other pathologies are not well described. Methods. We conducted a survey of staff at US pancreas transplant programs (March 22, 2022, to August 22, 2022) to assess current program practices and perceptions about the utility and challenges in the performance and interpretation of pancreas allograft biopsies. Results. Respondents represented 65% (76/117) of active adult pancreas transplant programs, capturing 66% of recent pancreas transplant volume in the United States. Participants were most often nephrologists (52%), followed by surgeons (46%), and other staff (4%). Pancreas allograft biopsies were performed mostly by interventional radiologists (74%), followed by surgeons (11%), nephrologists (8%), and gastroenterologists (1%). Limitations in the radiologist’s or biopsy performer’s comfort level or expertise to safely perform a biopsy, or to obtain sufficient/adequate samples were the two most common challenges with pancreas transplant biopsies. Pancreas transplant biopsies were read by local pathologists at a majority (86%) of centers. Challenges reported with pancreas biopsy interpretation included poor reliability, lack of reporting of C4d staining, lack of reporting of rejection grading, and inconclusive interpretation of the biopsy. Staff at a third of responding programs (34%) stated that they rarely or never perform pancreas allograft biopsies and treat presumed rejection empirically. Conclusions. This national survey identified significant variation in clinical practices related to pancreas allograft biopsies and potential barriers to pancreas transplant utilization across the United States. Consideration of strategies to improve program experience with percutaneous pancreas biopsy and to support optimal management of pancreas allograft rejection informed by histology is warranted.

Abstract Background Since November 2019, the SARS-CoV-2 pandemic has created challenges for preventing and managing COVID-19 in children and adolescents. Most research to develop new therapeutic interventions or to repurpose existing ones has been undertaken in adults, and although most cases of infection in pediatric populations are mild, there have been many cases of critical and fatal infection. Understanding the risk factors for severe illness and the evidence for safety, efficacy, and effectiveness of therapies for COVID-19 in children is necessary to optimize therapy. Methods A panel of experts in pediatric infectious diseases, pediatric infectious diseases pharmacology, and pediatric intensive care medicine from 21 geographically diverse North American institutions was re-convened. Through a series of teleconferences and web-based surveys and a systematic review with meta-analysis of data for risk factors, a guidance statement comprising a series of recommendations for risk stratification, treatment, and prevention of COVID-19 was developed and refined based on expert consensus. Results There are identifiable clinical characteristics that enable risk stratification for patients at risk for severe COVID-19. These risk factors can be used to guide the treatment of hospitalized and non-hospitalized children and adolescents with COVID-19 and to guide preventative therapy where options remain available.

AbstractBackgroundFor blood‐based biomarkers to fulfill their potential to revolutionize diagnosis and management of Alzheimer’s disease (AD), additional research in diverse populations remains critical. Here, we analyzed a biracial sample to assess the profiles of blood‐based AD biomarkers and their relationships to cognition and medical comorbidities.MethodsSelf‐reported African‐American (AA; n = 267) and non‐Hispanic White (NHW; n = 268) participants evaluated through the Mayo Jacksonville Alzheimer’s Disease Research Center were matched on age, sex, and clinical diagnosis. Plasma AD biomarkers (Aβ42/40, p‐tau181, GFAP, NfL) were measured using the Quanterix SiMoA HD‐X analyzer. Cognition was assessed with the Mini Mental State Examination. Wilcoxon rank sum tests were used to assess for differences in plasma biomarker levels by sex. Linear models tested for associations of race, chronic kidney disease (CKD), and vascular risk factors with plasma AD biomarker levels, covarying for age and sex. Additional models assessed for interactions between race and plasma biomarkers in predicting cognition, further covarying for education.ResultsThe sample included adults aged 43‐100 years, with 69% women. Education was higher in NHW participants (median 16 vs. 12 years, p<0.001). APOE (apolipoprotein E) ε4 positivity was higher in AA participants (43% vs. 34%; p = 0.04). There were no differences in plasma AD biomarker levels between AA and NHW participants. These findings were unchanged after stratifying by cognitive status (unimpaired versus impaired). Although the association between p‐tau181 and cognition appeared stronger in NHW participants while the association between Aβ42/40 and cognition appeared stronger in AA participants, these findings did not survive after excluding individuals with CKD. Women displayed higher GFAP (p = 0.002) and lower p‐tau181 (p = 0.001) levels than men. Diabetes was inversely associated with GFAP levels (p<0.001).ConclusionsIn a biracial, community‐based sample, we observed that sex differences, CKD, and vascular risk factors contributed to variation in plasma AD biomarkers, while self‐reported race did not. Our results reinforce the critical need to account for sex and systemic medical comorbidities in equitably deploying blood‐based AD biomarkers in the general population.

Abstract Background Post-discharge culture and susceptibility review has been described in emergency department and urgent care settings, but there is a lack of published literature describing culture review after acute care hospitalizations. Awaiting microbiology results can impede timely patient discharge. However, discharging patients while microbiology results are pending may result in suboptimal therapy or lost opportunity for additional testing/follow up. We implemented an antimicrobial stewardship effort to identify microbiology tests that result post-discharge utilizing a custom report in the electronic medical record (EMR). Methods. This retrospective descriptive study included adult patients ( &gt;18 years of age) at 4 sites within Mayo Clinic from 1/1/2019 to 2/28/2023. Eligible patients had a hospitalization with an ID consult and an abnormal culture that was reviewed by an antimicrobial stewardship pharmacist after discharge. Urine cultures were excluded. The details of pharmacist-initiated antimicrobial stewardship interventions based on the culture review were identified by an EMR based research report. Results A total of 6803 patient encounters with at least 1 microbiology result reviewed post-discharge were identified. Patients were 40% female with a median age of 62 years. Patient race was 89.8% white, 4% black/African American, 1.5% Asian, and &lt; 1% other. Of these patients, 1983 (29%) had at least one pharmacist intervention. A total of 169 (2.5%) of these patients had multiple interventions. Interventions included modification of antimicrobial therapy, addition of susceptibility testing, or additional follow up (labs, imaging, or patient visits). Median time from culture update to pharmacist review was 27.2 hours. Median length of hospital stay was 5 days and discharge disposition was home with self care (65%), home with home health or hospice (22.7%), or discharge to another acute care or skilled nursing facility (12.3%). Conclusion Outpatient review of post-discharge culture updates utilizing EMR reporting led to substantial interventions impacting antimicrobial treatments. Disclosures Christina G.

Background For individuals living with chronic conditions like diabetes mellitus and obesity, there is a need for sustainable behavioral strategies and physiologic tools. These tools support identifying and addressing barriers to healthy eating, reducing body mass index (BMI), and building increased physical resilience in real time. Objective To evaluate whether a 12-week learning management system designed to combine nutritional intervention with education and coaching on improving emotional intelligence (EI) could alter cardiometabolic outcomes. Methods This pre-post prospective study enrolled 37 adult volunteers with BMI greater than 25 to participate in a 12-week learning management system. Primary (BMI, systolic blood pressure, diastolic blood pressure, low-density lipoprotein [LDL], high-density lipoprotein, and fasting glucose levels) and secondary self-reported outcomes were assessed at baseline, 12 weeks, and 6 months after enrollment using Short Form-36, Emotional Quotient Inventory (EQi), and Whole Health Index (WHI). Linear mixed-effects regression models with random effect were used to estimate changes in primary and secondary outcomes. We adjusted for multiple testing using Holm step-down method. Results BMI and LDL were the only primary endpoints lower at program completion and 6-month follow-up compared to baseline levels (−1.63 and −17.77 mg/dL, respectively; P < .001). Secondary outcomes showing statistically significant improvement from baseline to 6-month follow-up included energy/fatigue (Short Form-36), self-regard (EQi), decision-making (EQi), impulse control (EQi), stress management (EQi), Whole Brain – Form A (WHI), Whole Food – Form C (WHI), and Whole Body – Form D (WHI). Conclusion This study provides preliminary evidence that lifestyle programs combining nutritional interventions and EI can have a significant impact on BMI and LDL. Our study highlights the potential importance of both nutrition and EI in programs targeting diet and lifestyle modification.
