Abstract This study explores the prevalence of urinary incontinence among multi-ethnic refugee women and their comfort levels in discussing this topic with their healthcare providers. Between July and November 2021, 58 refugee women were recruited within community spaces using convenience sampling and word-of-mouth. They completed a 20-item questionnaire in Arabic, Burmese, Swahili, or Somali. Urinary incontinence was identified by an affirmative response to any of the 6-item Urogenital Distress Inventory questions or the report of at least one episode of stress or urgency incontinence per month. The observed prevalence of urinary incontinence in this cohort was 50%. Despite 59.6% of participants expressing comfort in discussing these symptoms, 82.8% of them revealed that they had never spoken with a healthcare provider about them. Moreover, 77.6% of these women reported never being queried about these symptoms by a healthcare professional. Based on these results, urinary incontinence is notably prevalent among refugee women, either surpassing or at least aligning with the prevalence observed in the general female population. Healthcare professionals serving refugee women should consider incorporating screening for this condition into routine office visits. Notably, the limited sample size of this study underscores the necessity for further research on this subject.

Abstract Objectives There is limited research on suicide risk screening (SRS) among head and neck cancer (HNC) patients, a population at increased risk for suicide. To address this gap, this single-site mixed methods study assessed oncology professionals' perspectives about the feasibility, acceptability, and appropriateness of an electronic SRS program that was implemented as a part of routine care for HNC patients. Methods Staff who assisted with SRS implementation completed (e.g., nurses, medical assistants, advanced practice providers, physicians, social workers) a one-time survey (N = 29) and interview (N = 25). Quantitative outcomes were assessed using previously validated feasibility, acceptability, and appropriateness measures. Additional qualitative data were collected to provide context for interpreting the scores. Results Nurses and medical assistants, who were directly responsible for implementing SRS, reported low feasibility, acceptability, and appropriateness, compared with other team members (e.g., physicians, social workers, advanced practice providers). Team members identified potential improvements needed to optimize SRS, such as hiring additional staff, improving staff training, providing different modalities for screening completion among individuals with disabilities, and revising the patient-reported outcomes to improve suicide risk prediction. Conclusion Staff perspectives about implementing SRS as a part of routine cancer care for HNC patients varied widely. Before screening can be implemented on a larger scale for HNC and other cancer patients, additional implementation strategies may be needed that optimize workflow and reduce staff burden, such as staff training, multiple modalities for completion, and refined tools for identifying which patients are at greatest risk for suicide.

Abstract Medical researchers are increasingly prioritizing the inclusion of underserved communities in clinical studies. However, mere inclusion is not enough. People from underserved communities frequently experience chronic stress that may lead to accelerated biological aging and early morbidity and mortality. It is our hope and intent that the medical community come together to engineer improved health outcomes for vulnerable populations. Here, we introduce Health Equity Engineering (HEE), a comprehensive scientific framework to guide research on the development of tools to identify individuals at risk of poor health outcomes due to chronic stress, the integration of these tools within existing healthcare system infrastructures, and a robust assessment of their effectiveness and sustainability. HEE is anchored in the premise that strategic intervention at the individual level, tailored to the needs of the most at-risk people, can pave the way for achieving equitable health standards at a broader population level. HEE provides a scientific framework guiding health equity research to equip the medical community with a robust set of tools to enhance health equity for current and future generations.

Abstract Introduction Pathogenic mutations in POLE/POLD1 lead to decreased fidelity of DNA replication, resulting in a high tumor mutational burden (TMB-H), defined as TMB ≥ 10 mut/Mb, independent of deficient mismatch repair (dMMR) and microsatellite instability high (MSI-H) status. Methods De-identified records of patients with colorectal cancer (CRC) profiled with the Tempus xT assay (DNA-seq of 595-648 genes at 500×) were identified from the Tempus Database. Results Among 9136 CRC samples profiled, the frequency of POLE/POLD1 genomic alterations was 2.4% (n = 217). Copy number loss was the most common genomic alteration (64%, n = 138) of POLE/POLD1, followed by copy number amplifications (18%, n = 40) and short variant mutations (18%, n = 39). The POLE/POLD1 mutated group presented with a higher frequency of TMB-H phenotype relative to wild type (WT; 22% vs. 9%, P < .001), with a median TMB of 127 mut/Mb in the TMB-H POLE/POLD1 subset. The TMB showed a dramatic contrast between POLE/POLD1 short variant mutations as compared to the group with copy number alterations, with a TMB of 159 mut/Mb vs 15 mut/Mb, respectively. Thus, the short variant mutations represented the so-called ultra-hypermutated phenotype. The POLE/POLD1 mutated group, as compared to WT, exhibited a higher rate of coexisting mutations, including APC, ALK, ATM, BRCA2, and RET mutations. Conclusion Patients with POLE/POLD1 mutations exhibited significant differences across immunological markers (ie, TMB, MMR, and MSI-H) and molecular co-alterations. Those with short variant mutations represented 18% of the POLE/POLD1 cohort and 0.4% of the total cohort examined. This group of patients had a median TMB of 159 mut/Mb (range 34-488), representing the ultra-hypermutated phenotype. This group of patients is important to identify given the potential for exceptional response to immune checkpoint inhibitors.

A community of practice (CoP) is a group of people who share a concern or a passion for something they do and learn how to do it better as they interact regularly. While the field of hematology/oncology has historically prioritized clinical care and biomedical research, medical education has received increasing attention within hematology/oncology in recent years. In 2018, ASCO launched the Education Scholars Program to train hematology/oncology clinicians in the science of teaching and learning. However, the number of hematology/oncology educators nationally and internationally far exceeds the capacity of the Education Scholars Program to train them. In addition, hematology/oncology educators often lack sufficient mentorship and guidance at their own institutions to pursue their chosen career path effectively. To ensure high-quality clinical care and research for generations to come, attention must be paid to improving support for hematology/oncology educators. Therefore, supported by ASCO, we developed an international medical education (Med Ed) CoP for hematology/oncology educators with the purpose of providing them with support, community, mentorship, resources, and scholarly opportunities in medical education. In this article, we describe the development of the Med Ed CoP using a three-stage framework (Establish-Grow-Sustain) including successes, challenges, and reflections. By supporting the needs of hematology/oncology educators, the Med Ed CoP will serve as a home for all who contribute to the field of hematology/oncology.

Abstract Predominant limbic degeneration has been associated with various underlying aetiologies and an older age, predominant impairment of episodic memory and slow clinical progression. However, the neurological syndrome associated with predominant limbic degeneration is not defined. This endeavour is critical to distinguish such a syndrome from those originating from neocortical degeneration, which may differ in underlying aetiology, disease course and therapeutic needs. We propose a set of clinical criteria for a limbic-predominant amnestic neurodegenerative syndrome that is highly associated with limbic-predominant age-related TDP-43 encephalopathy but also other pathologic entities. The criteria incorporate core, standard and advanced features, including older age at evaluation, mild clinical syndrome, disproportionate hippocampal atrophy, impaired semantic memory, limbic hypometabolism, absence of neocortical degeneration and low likelihood of neocortical tau, with degrees of certainty (highest, high, moderate and low). We operationalized this set of criteria using clinical, imaging and biomarker data to validate its associations with clinical and pathologic outcomes. We screened autopsied patients from Mayo Clinic and Alzheimer’s Disease Neuroimaging Initiative cohorts and applied the criteria to those with an antemortem predominant amnestic syndrome (Mayo, n = 165; Alzheimer’s Disease Neuroimaging Initiative, n = 53) and who had Alzheimer’s disease neuropathological change, limbic-predominant age-related TDP-43 encephalopathy or both pathologies at autopsy. These neuropathology-defined groups accounted for 35, 37 and 4% of cases in the Mayo cohort, respectively, and 30, 22 and 9% of cases in the Alzheimer’s Disease Neuroimaging Initiative cohort, respectively. The criteria effectively categorized these cases, with Alzheimer’s disease having the lowest likelihoods, limbic-predominant age-related TDP-43 encephalopathy patients having the highest likelihoods and patients with both pathologies having intermediate likelihoods. A logistic regression using the criteria features as predictors of TDP-43 achieved a balanced accuracy of 74.6% in the Mayo cohort, and out-of-sample predictions in an external cohort achieved a balanced accuracy of 73.3%. Patients with high likelihoods had a milder and slower clinical course and more severe temporo-limbic degeneration compared to those with low likelihoods. Stratifying patients with both Alzheimer’s disease neuropathological change and limbic-predominant age-related TDP-43 encephalopathy from the Mayo cohort according to their likelihoods revealed that those with higher likelihoods had more temporo-limbic degeneration and a slower rate of decline and those with lower likelihoods had more lateral temporo-parietal degeneration and a faster rate of decline. The implementation of criteria for a limbic-predominant amnestic neurodegenerative syndrome has implications to disambiguate the different aetiologies of progressive amnestic presentations in older age and guide diagnosis, prognosis, treatment and clinical trials.

AbstractStudies suggest that self‐reported seizure diaries suffer from 50% under‐reporting on average. It is unknown to what extent this impacts medication management. This study used simulation to predict the seizure outcomes of a large heterogeneous clinic population treated with a standardized algorithm based on self‐reported seizures. Using CHOCOLATES, a state‐of‐the‐art realistic seizure diary simulator, 100 000 patients were simulated over 10 years. A standard algorithm for medication management was employed at 3 month intervals for all patients. The impact on true seizure rates, expected seizure rates, and time‐to‐steady‐dose were computed for self‐reporting sensitivities 0%–100%. Time‐to‐steady‐dose and medication use mostly did not depend on sensitivity. True seizure rate decreased minimally with increasing self‐reporting in a non‐linear fashion, with the largest decreases at low sensitivity rates (0%–10%). This study suggests that an extremely wide range of sensitivity will have similar seizure outcomes when patients are clinically treated using an algorithm similar to the one presented. Conversely, patients with sensitivity ≤10% would be expected to benefit (via lower seizure rates) from objective devices that provide even small improvements in seizure sensitivity.

Objective: To determine out-of-pocket (OOP) costs 2 years after sleeve gastrectomy (SG) or initiating Ozempic for patients with type 2 diabetes (T2D) and obesity. Background: Individuals with obesity and T2D have a variety of treatment options. The risks and benefits of these treatment options are becoming more well-documented; however, the real-world patient costs of these options are not known. Methods: Adults with body mass index of 35 kg/m2 or higher and T2D who had an SG or used Ozempic were identified in the employer-based retrospective claims database Merative (previously Truven IBM Marketscan) from 2017 to 2021. SG cohort was defined as having an SG (without filling a prescription for Ozempic), and the Ozempic cohort was defined as continuously filling a prescription for Ozempic for at least 2 years (and not having any bariatric surgery). Individuals in each cohort were 1:1 propensity matched on demographics, obesity-related comorbidities, and baseline OOP costs. in the year before treatment. OOP costs were compared in the 2 years after treatment using paired t tests. Results: A total of 302 SGs were matched to 302 Ozempic patients (mean age: 50, mean baseline body mass index: 40, 41% males). OOP health care costs were similar for the SG ($2267) and Ozempic ($2131) cohorts 1 year after the index date (difference = $136, P = 0.19). OOP health care costs were significantly lower in the SG cohort ($1155 vs $2,084, P < 0.01) 2 years after the index date. Conclusions: Within 2 years of starting treatment, OOP health care costs were significantly lower among individuals who had a SG versus those treated with Ozempic.

Abstract Neuroblastoma is an embryonic cancer that contributes disproportionately to death in young children. Sequencing data have uncovered few recurrently mutated genes in this cancer, although epigenetic pathways have been implicated in disease pathogenesis. We used an expression-based computational screen that examined the impact of deubiquitinating enzymes on patient survival to identify potential new targets. We identified the histone H2B deubiquitinating enzyme USP44 as the enzyme with the greatest impact on survival in patients with neuroblastoma. High levels of USP44 significantly correlate with metastatic disease, unfavorable histology, advanced patient age, and MYCN amplification. The subset of patients with tumors expressing high levels of USP44 had significantly worse survival, including those with tumors lacking MYCN amplification. We showed experimentally that USP44 regulates neuroblastoma cell proliferation, migration, invasion, and neuronal development. Depletion of the histone H2B ubiquitin ligase subunit RNF20 resulted in similar findings, strongly implicating this histone mark as the target of USP44 activity in this disease. Integration of transcriptome and epigenome in analyses demonstrates a distinct set of genes that are regulated by USP44, including those in Hallmark MYC target genes in both murine embryonic fibroblasts and the SH-SY5Y neuroblastoma cell line. We conclude that USP44 is a novel epigenetic regulator that promotes aggressive features and may be a novel target in neuroblastoma. Implications: This study identifies a new genetic marker of aggressive neuroblastoma and identifies the mechanisms by which its overactivity contributes to the pathophysiology of this disease.
