AbstractBackgroundDue to the immune‐mediated nature of non‐infectious cutaneous vasculitis, skin biopsy specimens are often submitted for direct immunofluorescence (DIF) testing when vasculitis is considered clinically. However, evidence regarding the clinical value of DIF has not been rigorously appraised.ObjectiveIn this scoping review, we aimed to systematically evaluate the peer‐reviewed literature on the utility of DIF in vasculitis to assist with the development of appropriate use criteria by the American Society of Dermatopathology.MethodsTwo electronic databases were searched for articles on DIF and vasculitis (January 1975–October 2023). Relevant case series involving more than or equal to three patients, published in English, and with full‐text availability were included. Additional articles were identified manually via reference review. Due to study heterogeneity, findings were analyzed descriptively.ResultsOf 255 articles identified, 61 met the inclusion criteria. Cumulatively representing over 1000 DIF specimens, several studies estimated DIF sensitivity to be 75%. While vascular immunoglobulin A (IgA) deposits on DIF were associated with renal disease, other systemic associations were inconsistent. Vascular IgG deposition may be overrepresented in ANCA‐associated vasculitis. Granular vascular and epidermal basement membrane zone Ig deposition differentiated hypocomplementemic from normocomplementemic urticarial vasculitis. Few studies have assessed the added value of DIF over routine microscopy alone in vasculitis.ConclusionsThis scoping review discovered that DIF testing for vasculitis has been performed not only for diagnostic confirmation of vasculitis but also for disease subtype classification and prediction of systemic associations. Future studies on test sensitivity of DIF compared to that of histopathology are needed.

Abstract Recent work in causally interpretable meta-analysis (CIMA) has bridged the gap between traditional meta-analysis and causal inference. Whereas traditional meta-analysis results generally do not apply to any well-defined population, CIMA approaches specify a target population to which meta-analytic treatment effect estimates are transported. Although theoretically attractive, these approaches currently have some practical limitations. Most assume that all studies in the meta-analysis have individual participant data (IPD), which is rare in practice because most trials share only aggregate data. We propose a method to perform CIMA using a combination of aggregate data and IPD. This method borrows information from studies with IPD to augment the aggregate data and create aggregate-matched synthetic IPD (AMSIPD), which can be used readily in the existing CIMA framework. By allowing use of both aggregate data and IPD, the method opens CIMA to more applications and can avoid biases arising from using only studies with IPD. We present a case study and simulations showing the AMSIPD approach is promising and merits further investigation as an advancement of CIMA.

Abstract Background Perianal draining tunnels in hidradenitis suppurativa (HS) and perianal fistulizing inflammatory bowel disease (IBD) present diagnostic and management dilemmas. Methods We conducted a retrospective chart review of patients with perianal disease evaluated at Mayo Clinic from January 1, 1998, through July 31, 2021. Patients' demographic and clinical data were extracted, and 28 clinical features were collected. After experimenting with several machine learning techniques, random forests were used to select the 15 most important clinical features to construct the diagnostic prediction model to distinguish perianal HS from fistulizing perianal IBD. Results A total of 263 patients were included (98 with HS, 100 with IBD, and 65 with both IBD and HS). Patients with HS had a higher mean body mass index, a higher smoking rate, and more commonly showed cutaneous manifestations of tunnels and comedones, while fistulas, abscesses, induration, anal tags, ulcers, and anal fissures were more common in patients with IBD. In addition to having lesions in the perianal area, patients with IBD often had lesions in the buttocks and perineum, while those with HS had additional lesions in the axillae and groin. Among the statistically significant features, the 15 most important were identified by random forest: fistula , tunnel , digestive symptom , knife‐cut ulcer , perineum , body mass index , age , axilla , abscess , tags , smoking , groin , genital cutaneous edema , erythema , and bilateral/unilateral . Conclusions The results of this study may help differentiate perianal lesions, especially perineal HS and fistulizing perineal IBD, and provide promise for a better therapeutic outcome.

AbstractThe emergence of the United States Food and Drug Administration (FDA)‐approved amyloid‐targeting therapies for Alzheimer's disease challenges clinicians and healthcare providers with a transformative landscape. Effectively communicating the risks, benefits, burdens, costs, and available support associated with these novel disease‐modifying treatments to patients, families, and other healthcare providers is essential but complex. In response, the Alzheimer's Association's Clinical Meaningfulness Workgroup has proposed language surrounding treatment eligibility, benefits, amyloid‐related imaging abnormalities (ARIA), apolipoprotein E (APOE) genotyping, and treatment costs, serving as a resource to healthcare professionals in navigating discussions with patients and their families. As the landscape evolves with the approval of new Alzheimer's therapies, this resource stands poised for updates, ensuring its continued relevance in facilitating informed and meaningful patient‐provider dialogues.Highlights Effective communication of risks, benefits, burdens, and costs of FDA‐approved amyloid‐targeting antibodies is essential to patients, families, and healthcare providers. The Alzheimer's Association's Clinical Meaningfulness Workgroup provides language for physicians and healthcare providers around treatment eligibility, benefits, ARIA, APOE genotyping, and treatment costs. This supplementary resource may be updated as new AD therapies become approved.

In recent years, the landscape of healthcare delivery has evolved significantly, with a growing emphasis on innovative approaches to patient care. The specialty of hospital medicine is new but evolving quickly over the past couple years. Also a new concept of advanced care at home has gained traction as a viable option for managing certain medical conditions traditionally treated in hospital settings. This presentation aims to explore the benefits, challenges, and implications of hospital medicine in healthy system with advanced care at home programs. During the session, we will delve into key aspects such as: • The evolution of hospital medicine and its current role in healthcare systems. • Overview of advanced care at home programs: objectives, scope, and patient selection criteria. • Comparative analysis of outcomes between hospital-based care and advanced care at home. • Technological advancements and infrastructure necessary to support advanced care at home initiatives. I believe this topic is particularly relevant while discussing innovation and the future of medicine

Abstract Background: Sub-Saharan African immigrants (SSAI) in the United States (US) constitute one of the fastest-growing segments of the immigrant population. Between 2010 and 2018, the SSAI population in the US increased by 53%, significantly outpacing the 12% growth rate for the overall foreign-born population in the US during that period. We define SSAI as the 2 million individuals living in the US originally from the region of the African continent located south of the Saharan desert. Despite their growing numbers, little is published about the extent to which SSAI adapt to health behaviors more common in the US or remain immersed in the values, beliefs, and practices reflective of their country of origin. Importantly, no study has comprehensively examined the social determinants of health factors among this population and its influence on health-seeking behaviors and decision-making regarding prostate cancer care and treatment. Aim: This study seeks to better understand the lived experiences, unmet needs and the impact of migration on the quality of life of SSAI cancer survivors in the US. Methods. We employ a qualitative approach guided by grounded theory. Selective sampling was used to identify potential participants from a database obtained via the Florida and Minesota cancer registries. We proceeded to conduct in-depth interviews with 16 cancer survivors recruited from the two caner registries. Results. We developed a conceptual framework illuminating the full range of social, behavioral, environmental, and structural factors associated with the experiences of SSAI prostate cancer survivors. From the data, the post diagnosis experiences of study participants can be categorized into three domains: 1) health behaviors; 2) treatment decision and antecedents; 3) challenges of being an immigrant. Characteristics of health behaviors include using informal care teams for social support and second opinions before treatment. Selective disclosure of diagnosis, changes to diet, exercise and searching for information about the diseases were other manifestation of behavior. While some participants made decisions about treatment soon after diagnosis, others took a more deliberative approach and relied on faith and family for social support. Some challenges in terms of being an immigrant include knowledge gaps about the US health system, lack of health insurance and transportation to hospital during treatment. Implication for public health practice. Some of the unmet needs of study participants include transportation cost to and from hospital for radiotherapy and other treatment and reducing the high out of pocket cost for co-payment and drugs. The knowledge deficit about navigating the US health system can be addressed through community-based intervention in partnerships with immigrant groups, advocacy organizations and faith-based organizations. The focus of this intervention should be to educate and empower SSAI men on how to navigate the US health system and be more assertive about their health needs and desires for treatment during doctor’s visit.

Abstract Cancer is the leading cause of mortality within the Latino population. Projections suggest a 142% increase in cancer incidence among Latinos over the next two decades. This trend is concerning given that Latinos, the largest minority group in the United States, are expected to constitute at least 28% of the nation's populace by 2060. To address the need for enhanced comprehension of these trends and to identify equitable interventions targeting Latino health disparities, the Institute of Health Promotion Research and the Mays Cancer Center jointly established the biennial Advancing the Science of Cancer in Latinos (ASCL) Conference. The fourth ASCL Conference convened in San Antonio, TX from February 21-23, 2024. The conference objectives were twofold: 1) Examine the intersection of health equity and biological underpinnings in cancer control, prevention, and treatment; and 2) Foster collaborative initiatives among attendees aimed at addressing cancer-related health disparities within the Latino community. The 2024 conference attracted 286 participants compared to 251 attendees in 2022, encompassing guest speakers, researchers, physicians, healthcare professionals, patient advocates, researchers, and students. It comprised 23 sessions (3 keynotes, 6 plenaries, 6 breakouts, 3 general sessions, 1 special session, 1 lunch panel session) featuring insights from 51 speakers, alongside a poster session highlighting 80 research abstracts and a rapid-fire session tailored for early-career investigators. Sessions encompassed multiple topics relevant to Latino cancer research, spanning health disparities, clinical trials, survivorship, patient advocacy, climate change impacts on cancer, precision medicine, health policy and social determinants of health. A post-conference survey from a cohort of 48 respondents underscored high levels of satisfaction, with 90% expressing pronounced contentment regarding the conference experience, compared to 85% in 2022. Moreover, nearly all respondents (98%) rated the relevance of conference content to Latino cancer science as excellent, with 93% regarding the conference as an exceptional platform for information exchange, compared to 79% in 2022. Impressions regarding session quality were overwhelmingly positive, with 90% of respondents indicating a high level of satisfaction, and all survey respondents acknowledging the objectivity, balance, and absence of commercial bias in the session content. Our results showed that the resounding positivity in attendee feedback reflects the conference's success in fostering meaningful engagement among researchers committed to alleviating Latino cancer health disparities. The ASCL conference facilitated an understanding of cultural nuances and barriers specific to the Latino community, stimulating collaborative efforts aimed at enhancing Latino health outcomes. Overall, this retrospective analysis affirms the conference's success in achieving its stipulated objectives and underscores the need of having consistently coordinated research endeavors to reduce Latino health disparities.

Abstract Introduction: Tribal Nations across the Southwest have striking disparities in cancer incidence and mortality. Compounded by disproportionately low rates of cancer screening and limited access to healthcare, Native Americans are more often diagnosed at later stages of disease and have the poorest outcomes in all types of cancer when compared to any other racial and ethnic group in the United States. At the University of New Mexico Comprehensive Cancer Center, the Participant Engagement Cancer Genomic Sequencing (PE-CGS) Center is developing culturally appropriate materials and strategies to enhance the engagement and recruitment of Native Americans into genomic research. This effort aims to determine participant knowledges, attitudes, cultural beliefs, and communication preferences regarding clinical genomics testing. Ultimately, targeting improvement of cancer outcomes in Southwestern Tribal communities. Cultural adaptations are crucial with regards to biospecimen collection, storage, and usage, due to historical mistrust of research among Native communities. (i.e., Havasupai Tribe v. the Arizona Board of Regents). A Tribal Advisory Committee, consisting of Tribal leaders, Native physicians, and patient advocates oversee all aspects of the research study. The goal is to identify appropriate optimized health literacy strategies for engaging Native peoples in cancer genomic research. Methods: The team conducted semi-structured discussions with participants to understand their perspectives on motivations to join, cultural safety components, and effectiveness of engagement strategies. With participant consent, the discussions were recorded and transcribed. Analysis included the transcripts and notes taken by the interviewer and followed Grounded Theory principles. All transcripts and notes followed line-by-line analysis by three of the authors (JS, JR and TG) who met regularly to identify and discuss emergent themes. Results: As of May 31, 2024, the PE-CGS study has enrolled 112 participants and completed 39 discussions. Participants emphasized altruistic motives tied to family and community, echoing traditional values, in their decision to participate in the study. This notion emerged during interactions with Native team members, where comfort stemmed from shared experiences (healthcare system, barriers), use of Native language, and adherence to Native social norms. Additional considerations included present autonomy throughout various stages of the study (sample use, data sharing, discussions). Return of genetic testing results improved understanding of treatment options, hereditary risk, and health literacy. Conclusion: Feedback highlights the importance of aligning cultural beliefs with Western medicine through a strengths-based approach. The findings will inform improvements in respectful engagement, communication, information exchange, and recruitment processes with Native American cancer patients and cancer survivors to genomic testing studies.

Abstract Purpose: The Mayo Clinic Comprehensive Cancer Center (MCCCC) serves its communities through every pillar of the cancer continuum from prevention to survivorship. To effectively educate our communities along this continuum, MCCCC partnered with a trusted community partner, leveraged the stories of survivors, and addressed stigma in a safe space for community members to ask vulnerable questions. Methods: The MCCCC partnered with Pamoja Women on the Friend-to-Friend initiative. Pamoja Women is a trusted community partner supporting East African women and their families, some of whom are refugees. They provided the space to hold each event, an environment where the women were comfortable with support from their community. The program highlighted cancer education, screening, and risk reduction through culturally appropriate discussions between friends. Topics were identified based on community interest and the cancer incidence in the community. Survivors shared their personal stories and medical experts discussed prevention, risk reduction, screening, addressed myths, answered questions, and showcased discoveries in research and treatment methods. Results: We have held 3 events covering breast, cervical, and HPV vaccination. Each event saw an increase in participation with almost 50 participants attending the series. Furthermore, there was an increase in awareness of screening methods, prevention, and risk reduction. Pamoja Women provided navigation to screening through transportation to and advocacy during appointments. This continuity from education to screening led to heading the call to action for screening. Due to its success, the four-part series has been expanded to include the topics of endometrial, prostate cancer, and breast cancer for a second time. Conclusion: Partnering with trusted community organizations has led to safe spaces for cancer education with friends. This approach has led to successful education and navigation to screening in communities that do not always have access to this essential information.

Abstract Introduction: Black men experience a significant burden and face greater hurdles in the prevention, detection, treatment, and survival of prostate cancer (CaP). To address barriers and systemic issues associated with CaP, we have established Community Living Lab (CoLLab) Learning Health Systems through a partnership with the American Legion Post (ALP) and Mayo Clinic. The focus is on providing comprehensive prostate health resources, education, amenities, and community health services (REACH). This initiative represents a proactive approach to addressing health disparities in prostate cancer prevention, detection, and treatment to improve CaP health equity for Black men. This study has three primary aims: (1) Co-develop a user-centric CoLLab Learning Health System with collaborating ALPs, (2) Evaluate the impact of the CoLLab Learning Health System using a pretest-posttest design, and (3) Explore the feasibility of replicating the CoLLab Learning Health System in Black communities nationally. Methods: Three ALPs in Northeast Florida are currently included in this pilot study. The study timeline spans 30 months, from October 2023 to March 2026. The target recruitment is 150 Black men aged 30 to 80 years. Community Health Workers (CHWs) are currently recruiting participants to complete the ALP Neighborhood assessment four times over 12 months to measure changes in CaP-related knowledge, attitudes, health beliefs, perceived control, intentions, and cues to action. Participants will be able to access prostate health REACH services at the designated ALPs through education, navigation, and support services. The program will be continuously evaluated for continuous improvement. The reach of the prostate health REACH services, including extent and patterns of use, demographics of participants reached, and successful navigation for social determinants of health (SDOH), clinical trials, and healthcare, will be evaluated. Additionally, participation in the Community Research Registry, indicating interest in being matched with clinical trials at Mayo Clinic, will be assessed. Results: To date, we have trained 10 CHWs for the study who will serve as community navigators to provide REACH services at their designated ALPs. We have had 49 Black men recruited into the study, and they have completed the baseline assessment at various events held at the ALPs. CaP survivors support group, led by ALP, has begun providing survivorship support services, including healthcare navigation, wellness programs, and grocery distribution to Black men and their households in the community surrounding the ALPs. Conclusion: The CoLLab initiative represents a proactive approach to addressing health disparities and improving outcomes for Black men in CaP prevention, detection, treatment, and survivorship. This study represents a crucial step towards eliminating CaP disparities experienced by Black men, contributing to improved health equity and outcomes in this population.
