Abstract Background: The National Comprehensive Cancer Network (NCCN) recommends the use of tissue-based genetic tests, such as Decipher, Prolaris, and Confirm mdx for localized prostate cancer, to help patients and caregivers make more informed treatment decisions at the time of diagnosis. However, while much enthusiasm currently exists for the burgeoning field of genomic medicine, prostate cancer disparities continue to persist in underserved communities despite the existence of evidence-based treatment guidelines. Methods: A diverse 15-member Community Advisory Board (CAB) representing rural and urban communities in Duval County, Florida were recruited from May to June 2023, to build a community-academic partnership, for the development and implementation of a genetic literacy patient-caregiver educational intervention for localized prostate cancer. The 15-member CAB was divided into groups of 5 for focus group discussions. Qualitative and quantitative data from CAB members were integrated to gain better understanding of the facilitators and barriers for prostate cancer genetic literacy in underserved communities. Results: The thematic analysis reveals several key themes related to prostate cancer, screening, treatment, and genetics. These themes reflect the diverse perspectives and experiences of the CAB members regarding prostate cancer, ranging from personal anecdotes to broader societal issues. Participants expressed thoughts related to fear, lack of knowledge, cultural beliefs, and access to healthcare. The discussion on prostate cancer and tissue based genetic testing highlighted the complexities surrounding prostate cancer and the need for further education, awareness, and access to affordable healthcare for all individuals at risk. Conclusion: CAB members emphasized the importance of improving access to information, promoting education, and addressing cultural barriers to ensure that individuals are informed about available options for prostate cancer diagnosis and treatment.

Abstract Introduction: Underrepresented communities experience a lack in research participation due to multifaceted barriers including historical research mistrust, language barriers, transportation inaccessibility, and other social determinants of health. The disproportionate representation in racial, ethnic, and medically underserved communities furthers the gap in health disparities and treatment outcomes. For this reason, the Mayo Clinic Community Research Registry (CoRR) was developed in 2022 to specifically create a registry of underrepresented communities and connect them to research studies. Methodology: Mayo Clinic CoRR utilizes a community based participatory research (CBPR) approach involving bidirectional engagement with community participants, partnership with community stakeholders and leaders, dissemination of clinical trial information, and use of evidence-based education materials for community outreach. CoRR community partnerships include fraternities, sororities, churches, the American Legion, local physicians, pharmacies, clinics, and health fair events. Through questionnaires, study participants indicate the level of research participation they are comfortable with and are matched to research studies based on their individualized responses. New Unpublished Data: As of early June 2023, CoRR has 270 participants enrolled in the registry with 94% of participants being Black and 6% Hispanic. Average age of the participants is 63 years and includes 63% female and 37 % male. As community input is vital to its development, Mayo Clinic CoRR has partnered with a community advisory board for ongoing discussion of study procedures and recruitment initiatives. This feedback has resulted in over 25 protocol modifications from bidirectional community input and engagement with the study to tailor it to community needs. Revisions include modification of inclusion and exclusion criteria to allow interested, low literacy participants to join, offering written and online platforms for participation in Somali, French, and Creole languages. CoRR adaptations have also implemented a community newsletter to visually provide updated CoRR information, highlight research studies in which CoRR participants have been included, as well as engage CoRR participants regularly. Future developments for CoRR include the establishment of an ad hoc Committee with registry participants to provide another level of safeguarding for enrolled CoRR participants. Conclusion: Responsivity to the needs of the community is vital for the continued development and success of Mayo Clinic CoRR, which has led to a successful ongoing enrollment of underrepresented communities into research studies. By utilizing targeted CBPR, the CoRR demonstrates a proof of concept in recruiting and retaining participants in hard-to-reach demographics with the goal of reducing health disparities in chronic diseases, including cancer.

Abstract Despite notable progress in early detection, prevention, and treatment of prostate cancer within the United States, racial disparities are present very early in the patient journey of Black men, starting with the shared decision-making process. The disproportionately higher number of Black men diagnosed with prostate cancer also suggests that Black men must also contend with the management of associated physiological and psychosocial symptoms. The survivorship care plan was designed to communicate critical information that cancer survivors and their health care advocates need as a guidebook for long term post treatment care, and improved survivorship. An associated systematic literature review conducted by our multidisciplinary investigative team revealed there was a severe underutilization of survivorship care plans within cancer survivorship care especially with Black men. The considerable lack of utilization and/or tailoring of survivorship care plans may be a significant contributor to the worsening of health disparities in this population. Co-designing survivorship care plans with key stakeholders, specifically Black survivors and their health care advocates, is imperative to ensure that the plan meets the needs and preferences that Black men have for survivorship care. This presentation will discuss the steps the investigative team used to address the disparities in shared decision-making, and the subsequent underutilization of survivorship care plans. The investigative team utilized semi-structured interviews and focus group methodology to explore how the lived experiences of Black male prostate cancer survivors are incorporated and addressed in the construction and contents of a culturally tailored survivorship care plan (CaP_SCP- Black Men). An evaluability assessment was conducted to determine whether implementation of the newly created survivorship care plan is feasible, appropriate, and addresses the specific needs of the population before full implementation. This presentation will discuss how this combination of approaches allowed the investigative team to understand how survivorship care plans affect the unique complexities of survivorship in Black men, and allows for the feasibility study of the implementation of a culturally relevant survivorship care plan (CaP_SCP- Black Men) in a population that bears the greatest burden nationally and globally.

Abstract Objective Given the importance AI in genomics and its potential impact on human health, the American Medical Informatics Association—Genomics and Translational Biomedical Informatics (GenTBI) Workgroup developed this assessment of factors that can further enable the clinical application of AI in this space. Process A list of relevant factors was developed through GenTBI workgroup discussions in multiple in-person and online meetings, along with review of pertinent publications. This list was then summarized and reviewed to achieve consensus among the group members. Conclusions Substantial informatics research and development are needed to fully realize the clinical potential of such technologies. The development of larger datasets is crucial to emulating the success AI is achieving in other domains. It is important that AI methods do not exacerbate existing socio-economic, racial, and ethnic disparities. Genomic data standards are critical to effectively scale such technologies across institutions. With so much uncertainty, complexity and novelty in genomics and medicine, and with an evolving regulatory environment, the current focus should be on using these technologies in an interface with clinicians that emphasizes the value each brings to clinical decision-making.

AbstractBackgroundRecent clinical trials have evaluated the efficacy of vonoprazan‐amoxicillin (VA) dual therapy as the first‐line treatment for Helicobacter pylori infection in different regions with inconsistent results reported. In this systematic review and meta‐analysis, we aimed to evaluate the efficacy of VA dual therapy compared to the currently recommended therapy for eradicating H. pylori.Materials and MethodsA comprehensive search of the PubMed, Cochrane, and Embase databases was performed using the following search terms: (“Helicobacter” OR “H. pylori” OR “Hp”) AND (“vonoprazan” OR “potassium‐competitive acid blocker” OR “P‐CAB”) AND (“amoxicillin” OR “penicillin”) AND (“dual”). The primary outcome was to evaluate the eradication rate according to intention‐to‐treat and per‐protocol analysis. The secondary outcomes were adverse events and compliance.ResultsA total of 15 studies involving 4, 568 patients were included. The pooled eradication rate of VA dual therapy was 85.0% and 90.0% by intention‐to‐treat and per‐protocol analysis, respectively. The adverse events rate and compliance of VA dual therapy were 17.5% and 96%, respectively. The efficacy of VA dual therapy was superior to proton pump inhibitors‐based triple therapy (82.0% vs. 71.4%, p < 0.01) but lower than vonoprazan‐containing quadruple therapy (83.1% vs. 93.3%, p = 0.02). 7‐day VA dual therapy showed lower eradication rates than 10‐day (χ2 = 24.09, p < 0.01) and 14‐day VA dual therapy (χ2 = 11.87, p < 0.01). The adverse events rate of VA dual therapy was lower than vonoprazan triple therapy (24.6% vs. 30.9%, p = 0.01) and bismuth‐containing quadruple therapy (20.5% vs. 47.9%, p < 0.01). No significant difference of compliance was observed between VA dual therapy and each subgroup.ConclusionVA dual therapy, a novel regimen, showed high efficacy as the first‐line treatment for H. pylori eradication, which should be optimized before application in different regions.

Abstract Background Amyloidosis is defined by abnormal protein folding and subsequent deposition in tissues. Cardiac involvement is usually related to misfolded monoclonal immunoglobulin light chains or misfolded transthyretin; however, apolipoprotein A-1–associated amyloidosis is a hereditary form of amyloidosis resulting from mutations in the AAPOA1 gene that can also result in cardiac amyloidosis. Although there have been advancements in noninvasive algorithms for the diagnosis of cardiac amyloidosis, endomyocardial biopsy (EMB) may still be warranted. All individuals undergoing EMB are susceptible to complications, including tricuspid valve injury resulting in severe tricuspid valve regurgitation. Case summary Our patient is a 70-year-old white man presented with symptoms of dyspnoea on exertion and decreased functional capacity, diagnosed previously with apolipoprotein A-I cardiac amyloidosis, confirmed by EMB. He developed progressive right-sided heart failure secondary to iatrogenic flail tricuspid leaflet related to the diagnostic EMB. He underwent a successful transcatheter tricuspid valve edge-to-edge repair with 4D intracardiac echocardiographic guidance. At the recent follow-up, the patient showed improved symptoms, with increased stamina, and transoesophageal echocardiography revealed a 65% ejection fraction and mild tricuspid regurgitation (TR). Discussion Tricuspid valve injury is one of the complications associated with EMB, which can result in severe TR. Transcatheter tricuspid valve edge-to-edge repair can be a useful option for patients considered too high risk for surgical intervention, such as those with advanced cardiac amyloidosis.

Single-molecule immunoassay is a reliable technique for the detection and quantification of low-abundance blood biomarkers, which are essential for early disease diagnosis and biomedical research. However, current single-molecule methods all require signal amplification via labelling, which brings a variety of unwanted consequences, such as matrix effects and autofluorescence interference. Here, we introduce a real-time mass imaging-based label-free single-molecule immunoassay (LFSM-immunoassay). Featuring plasmonic scattering microscopy-based real-time mass imaging, a 2-step sandwich assay format-enabled background reduction, and minimization of matrix effects by dynamic tracking of single binding events, the LFSM-immunoassay enables ultra-sensitive and direct protein detection at the single-molecule level in neat blood sample matrices. We demonstrated that the LFSM-immunoassay can measure sub-femtomolar levels of interleukin-6 and prostate-specific antigen in whole blood with 8 log dynamic range. To show its translational potential to clinical settings, we measured NT-proBNP (N-terminal pro-brain natriuretic peptide) in 28 patient serum samples using a 20 minute LFSM-immunoassay, and the results show a strong linear correlation (r > 0.99) with clinical lab reported values.

Abstract Background Tennis players often present with ulnar-sided wrist pain, which may reflect repetitive stress and/or faulty mechanics. There is a role for investigating the biomechanics of tennis strokes and how they may relate to wrist pathology. The purpose of this study was to investigate whether three-dimensional motion capture technology and dynamic electromyography (EMG), when used to study groundstrokes in elite junior tennis players, reveals patterns of upper extremity motion that may correlate with the development of clinically relevant pathology. Case Description Three-dimensional kinematic and EMG data were collected from two United States Tennis Association-ranked adolescent tennis players during groundstrokes. There were several observed differences in the two players' degree and timing of pronation/supination, ulnar/radial deviation, and flexion/extension during their strokes. Clinical Significance Advanced motion capture technology facilitates a nuanced understanding of complex movements involved in groundstroke production. This methodology may be useful for identifying athletes who are at risk for injury and guiding rehabilitation for players experiencing pain. Level of Evidence IV

AimsThe scapula is a rare site for a primary bone tumour. Only a small number of series have studied patient outcomes after treatment. Previous studies have shown a high rate of recurrence, with functional outcomes determined by the preservation of the glenohumeral joint and deltoid. The purpose of the current study was to report the outcome of patients who had undergone tumour resection that included the scapula.MethodsWe reviewed 61 patients (37 male, 24 female; mean age 42 years (SD 19)) who had undergone resection of the scapula. The most common resection was type 2 (n = 34) according to the Tikhoff-Linberg classification, or type S1A (n = 35) on the Enneking classification.ResultsThe ten-year disease-specific survival was 76%. High tumour grade (hazard ratio (HR) 4.27; p = 0.016) and a total resection of the scapula (HR 3.84; p = 0.015) were associated with worse survival. The ten-year metastasis-free and local recurrence-free survivals were 82% and 86%, respectively. Total scapular resection (HR 6.29; p = 0.004) was associated with metastatic disease and positive margins were associated with local recurrence (HR 12.86; p = 0.001). At final follow-up, the mean shoulder forward elevation and external rotation were 79° (SD 62°) and 27° (SD 25°), respectively. The most recent functional outcomes evaluated included the mean Musculoskeletal Tumor Society Score (76% (SD 17%)), the American Shoulder and Elbow Score (73% (SD 20%)), and the Simple Shoulder Test (7 (SD 3)). Preservation of the glenoid (p = 0.001) and scapular spine (p < 0.001) improved clinical outcomes; interestingly, preservation of the scapular spine without the glenoid improved outcomes (p < 0.001) compared to preservation of the glenoid alone (p = 0.05).ConclusionResection of the scapula is a major undertaking with an oncological outcome related to tumour grade, and a functional outcome associated with the status of the scapular spine and glenoid. Positive resection margins are associated with local recurrence.Cite this article: Bone Joint J 2023;105-B(12):1314–1320.
