Abstract Aims In patients with catecholaminergic polymorphic ventricular tachycardia (CPVT), a rare inherited arrhythmia syndrome, arrhythmic events can be prevented by medication and lifestyle recommendations. In patients who experience breakthrough arrhythmic events, non-adherence plays an essential role. We aimed to investigate the incidence and potential reasons for non-adherence to medication and lifestyle recommendations in a large, international cohort of patients with CPVT. Methods and results An online multilingual survey was shared with CPVT patients worldwide by their cardiologists, through peer-recruitment, and on social media from November 2022 until July 2023. Self-reported non-adherence was measured using the validated Medication Adherence Rating Scale (MARS) and a newly developed questionnaire about lifestyle. Additionally, validated questionnaires were used to assess potential reasons for medication non-adherence. Two-hundred-and-eighteen patients completed the survey, of whom 200 (92%) were prescribed medication [122 (61%) female; median age 33.5 years (interquartile range: 22–50)]. One-hundred-and-three (52%) were prescribed beta-blocker and flecainide, 85 (43%) beta-blocker, and 11 (6%) flecainide. Thirty-four (17%) patients experienced a syncope, aborted cardiac arrest or appropriate implantable cardioverter defibrillator shock after diagnosis. Nineteen (13.4%) patients were exercising more than recommended. Thirty (15%) patients were non-adherent to medication. Female sex [odds ratio (OR) 3.7, 95% confidence interval (CI) 1.3–12.0, P = 0.019], flecainide monotherapy compared to combination therapy (OR 6.8, 95% CI 1.6–31.0, P = 0.010), and a higher agreement with statements regarding concerns about CPVT medication (OR 1.2, 95% CI 1.1–1.3, P < 0.001) were independently associated with non-adherence. Conclusion The significant rate of non-adherence associated with concerns regarding CPVT-related medication, emphasizes the potential for improving therapy adherence by targeted patient education.

Background: Following the adoption of new nomenclature for steatotic liver disease, we aimed to build consensus on the use of International Classification of Diseases codes and recommendations for future research and advocacy. Methods: Through a two-stage Delphi process, a core group (n = 20) reviewed draft statements and recommendations (n = 6), indicating levels of agreement. Following revisions, this process was repeated with a large expert panel (n = 243) from 73 countries. Results: Consensus ranged from 88.8% to 96.9% (mean = 92.3%). Conclusions: This global consensus statement provides guidance on harmonizing the International Classification of Diseases coding for steatotic liver disease and future directions to advance the field.

529 Background: Radical cystectomy is recommended for patients with BCG-unresponsive (BU) non-muscle invasive bladder cancer (NMIBC) due to high risk of progression. Improved methods for assessing these risks would greatly facilitate the potential for bladder preservation. Here, we tested the capacity of the urinary comprehensive genomic profile (uCGP) to predict event-free survival (EFS) in patients with BU-NMIBC treated with atezolizumab in the single arm phase 2 trial SWOG S1605. Methods: Urine was collected from patients with BU NMIBC (CIS, Ta, T1) treated with at least one dose of intravenous atezolizumab at baseline and before the 5th cycle of therapy (3 months). The uCGP was assessed using UroAmp (Convergent Genomics). Risk scores for recurrence at baseline and at 3 months were calculated by a prespecified machine learning algorithm incorporating alterations in 60 genes and low pass whole genome sequencing, and categorized as high versus low. Molecular response was classified based on change in uCGP between the two time points. Risk scores and molecular response were submitted to SWOG for clinical correlation with EFS using a Cox model, adjusting for CIS status. Time to event was calculated from date of study entry (baseline risk) or from the 2nd collection time (3-month risk) to first high grade (HG) recurrence or persistent CIS at 3 months. Death unrelated to bladder cancer and patients last known to be alive without HG recurrence were censored at date of last visit. Results: Samples were provided at baseline in 89 patients and before the 5th cycle in 77; 68 had both samples available for paired analysis. The risk score at baseline was classified as high in 69% of samples (73% for CIS ±Ta/T1 and 62% for Ta/T1). At 12 and 18 months the EFS probabilities were 26% and 23% for high-risk and 67% and 51% for low-risk patients, respectively, with a HR of 2.82 (95% CI: 1.58, 5.03; p<0.001). The risk score at the 3-month timepoint was classified as high in 81% of samples, and the EFS probabilities at 12 and 18 months after urine collection were 26% and 22% for high-risk and 80% and 72% for low-risk patients, respectively, with a HR of 3.39 (95% CI: 1.41, 8.13; p<0.006). Molecular response to treatment was classified as complete (CR) in 8%, partial (PR) in 14%, stable (SD) in 25% and progression (PD) in 46%, with 7% having no detectable genomic abnormalities at both time points. Clinical recurrence was observed by 18 months in 0/6 patients with CR, 7/9 (78%) with PR, 11/14 (79%) with SD and 25/33 (76%) with PD by genomic profile. Conclusions: This study suggests that uCGP at baseline and after 4 cycles of treatment can identify genomic patterns associated with an increased risk of HG persistence, recurrence or progression in BU NMIBC treated with immune checkpoint inhibition. Future studies will determine if this can be used to guide early treatment intensification.

Background The Medicare Annual Wellness Visit (AWV) allows providers to acquire critical information about patients’ health through a review of vitals, environmental risks, and medical and family history. These visits are free to those enrolled in Medicare and prioritize patient–provider relationship building and preventative care. Despite this, AWV completion rates are suboptimal. Methods A quality improvement project was aimed to increase the percentage of AWVs among Medicare patients in a primary care internal medicine practice from a baseline of 1.7% completion to 2.7% in 3 months from January to April 2023. Intervention With eligible patients identified, a standardized approach was created where an AWV appointment was ordered, and a patient message explaining the benefit of the appointment was sent by the patient portal. Results Our AWV intervention resulted in 72 patients being seen for an AWV, which increased the percentage of completed AWVs in the division by 2.1% from 1.7% to 3.8% in 3 months. Conclusion This intervention will continue to improve AWV rates and improve patient care for Medicare patients in internal medicine. It could be applied to other areas of primary care and within other health systems.

22 Background: Glycosylation plays a pivotal role in host immune response during cancer development. Recently, we have reported specific changes in blood-based glycoforms for the early detection of advanced adenomas (AAs) and colorectal cancer (CRC). This study aims to identify glycoproteomic biomarkers associated with various polyp types, as glycosylation abnormalities are linked to neoplastic transformation, and CRC risk varies by polyp histology. Methods: Samples from an observational study (NCT05445570) were used to identify three distinct histologic polyp groups: adenomatous (AP), hyperplastic (HP), or serrated (SP). Combining liquid-chromatography/mass-spectrometry and artificial-intelligence powered data processing, our glycoproteomic profiling platform assessed glycopeptide (GP) and non-glycosylated peptide quantification transitions from the serum samples. We used multi-nominal response logit models to examine the relationship between polyp types and biomarkers. An a priori biomarker panel was interjected as exposures in the model. Each marker is assessed independently for inclusion into our final model. The final model utilized biomarkers found to have a significant association with the presence of AP, SP, or HPs along with age, sex, and BMI. Results: We identified 1,035 subjects with distinct polyp histologies and 1,300 polyp-free controls. We found a significant increase in relative risk (RR) for polyp presence in patients who were: >60 years (AP RR 1.40), male (AP RR 1.74), or had a BMI> 25. From the GP biomarker panel, 15 GPs were associated with risk of polyp presence; however, only 7 GP markers were significantly associated after adjusting for age, sex, and BMI. Two biomarkers were found to have a protective effect for the risk of an adenomatous polyp (RR 0.37; RR 0.39). Three biomarkers increased the risk of an adenomatous polyp (RR 1.31; RR 1.42; RR 1.98). One biomarker was found to increase the risk of a hyperplastic polyp (RR 1.42). Two biomarkers were found to increase the risk of serrated polyps (RR 1.67; RR 2.08) and one biomarker was found to decrease the risk of serrated polyps (RR 0.77). Conclusions: This is a novel exploratory study using GP biomarkers as it relates to risk of polyp presence by distinct histology. The use of these biomarkers allows us to harness the power of glycobiology in the liquid biopsy domain for AAs/CRC detection. The exact function of these GP markers during the development of different polyp types needs to be further explored through future studies.

AbstractEpilepsy imposes a substantial burden on the Democratic Republic of Congo (DRC). These challenges encompass the lack of comprehensive disease surveillance, an unresolved understanding of its pathophysiology, economic barriers limiting access to essential care, the absence of epilepsy surgical capabilities, and deeply ingrained societal stigmas. Notably, the national prevalence of epilepsy remains undetermined, with research primarily concentrating on infectious factors like Onchocerca volvulus, leaving other potential causes underexplored. Most patients lack insurance, incurring out‐of‐pocket expenses that often lead them to opt for traditional medicine rather than clinical care. Social stigma, perpetuated by common misconceptions, intensifies the social isolation experienced by individuals living with epilepsy. Additionally, surgical interventions are unavailable, and the accessibility of anti‐seizure medications and healthcare infrastructure remains inadequate. Effectively tackling these interrelated challenges requires a multifaceted approach, including conducting research into region‐specific factors contributing to epilepsy, increasing healthcare funding, subsidizing the costs of treatment, deploying mobile tools for extensive screening, launching awareness campaigns to dispel myths and reduce stigma, and promoting collaborations between traditional healers and medical practitioners to enhance local understanding and epilepsy management. Despite the difficulties, significant progress can be achieved through sustained and compassionate efforts to understand and eliminate the barriers faced by epilepsy patients in the region. This review outlines essential steps for alleviating the epilepsy burden in the DRC.Plain Language summaryThere are not enough resources to treat epilepsy in the DRC. PWEs struggle with stigma and the lack of money. Many of them still use traditional medicine for treatment and hold wrong beliefs about epilepsy. That is why there is a need for more resources to make the lives of PWEs better in the DRC.

OBJECTIVE It is not clear whether there is an additive effect of social factors in keeping patients with cervical spondylotic myelopathy (CSM) from achieving both a minimum clinically important difference (MCID) in outcomes and satisfaction after surgery. The aim of this study was to explore the effect of multiple social factors on postoperative outcomes and satisfaction. METHODS This was a multiinstitutional, retrospective study of the prospective Quality Outcomes Database (QOD) CSM cohort, which included patients aged 18 years or older who were diagnosed with primary CSM and underwent operative management. Social factors included race (White vs non-White), education (high school or below vs above), employment (employed vs not), and insurance (private vs nonprivate). Patients were considered to have improved from surgery if the following criteria were met: 1) they reported a score of 1 or 2 on the North American Spine Society index, and 2) they met the MCID in patient-reported outcomes (i.e., visual analog scale [VAS] neck and arm pain, Neck Disability Index [NDI], and EuroQol-5D [EQ-5D]). RESULTS Of the 1141 patients included in the study, 205 (18.0%) had 0, 347 (30.4%) had 1, 334 (29.3%) had 2, and 255 (22.3%) had 3 social factors. The 24-month follow-up rate was > 80% for all patient-reported outcomes. After adjusting for all relevant covariates (p < 0.02), patients with 1 or more social factors were less likely to improve from surgery in all measured outcomes including VAS neck pain (OR 0.90, 95% CI 0.83–0.99) and arm pain (OR 0.88, 95% CI 0.80–0.96); NDI (OR 0.90, 95% CI 0.83–0.98); and EQ-5D (OR 0.90, 95% CI 0.83–0.97) (all p < 0.05) compared to those without any social factors. Patients with 2 social factors (outcomes: neck pain OR 0.86, arm pain OR 0.81, NDI OR 0.84, EQ-5D OR 0.81; all p < 0.05) or 3 social factors (outcomes: neck pain OR 0.84, arm pain OR 0.84, NDI OR 0.84, EQ-5D OR 0.84; all p < 0.05) were more likely to fare worse in all outcomes compared to those with only 1 social factor. CONCLUSIONS Compared to those without any social factors, patients who had at least 1 social factor were less likely to achieve MCID and feel satisfied after surgery. The effect of social factors is additive in that patients with a higher number of factors are less likely to improve compared to those with only 1 social factor.

AbstractBackgroundPatient‐reported outcomes (PROs) are a better tool for evaluating the experiences of patients who have symptomatic, treatment‐associated adverse events (AEs) compared with clinician‐rated AEs. The authors present PROs assessing health‐related quality of life (HRQoL) and treatment‐related neurotoxicity for adjuvant capecitabine versus platinum on the Eastern Cooperative Oncology Group‐American College of Radiology Imaging Network (ECOG‐ACRIN) EA1131 trial (ClinicalTrials.gov identifier NCT02445391).MethodsParticipants completed the National Comprehensive Cancer Network Functional Assessment of Cancer Therapy–Breast Cancer Symptom Index (NFBSI‐16) and the Functional Assessment of Cancer Therapy–Gynecologic Oncology Group neurotoxicity subscale (platinum arm only) at baseline, cycle 3 day 1 (C3D1), 6 months, and 15 months. Because of early termination, power was insufficient to test the hypothesis that HRQoL, as assessed by the NFBSI‐16 treatment side‐effect (TSE) subscale, would be better at 6 and 15 months in the capecitabine arm; all analyses were exploratory. Means were compared by using t‐tests or the Wilcoxon rank‐sum test, and proportions were compared by using the χ2 test.ResultsTwo hundred ninety‐six of 330 eligible patients provided PROs. The mean NFBSI‐16 TSE subscale score was lower for the platinum arm at baseline (p = .02; absolute difference, 0.6 points) and for the capecitabine arm at C3D1 (p = .04; absolute difference, 0.5 points), but it did not differ at other times. The mean change in TSE subscale scores differed between the arms from baseline to C3D1 (platinum arm, 0.15; capecitabine arm, −0.72; p = .03), but not from baseline to later time points. The mean decline in Functional Assessment of Cancer Therapy–Gynecologic Oncology Group neurotoxicity subscale scores exceeded the minimal meaningful change (1.38 points) from baseline to each subsequent time point (all p < .05).ConclusionsDespite the similar frequency of clinician‐rated AEs, PROs identified greater on‐treatment symptom burden with capecitabine and complemented clinician‐rated AEs by characterizing patients’ experiences during chemotherapy.
