ABSTRACT As artificial intelligence (AI) continues to rapidly reshape health care, there is a critical need for clear frameworks for clinicians to ensure ethical, equitable, and effective integration and use of AI in patient care. Key integrations of AI include enhancing health communications, patient engagement, clinicians' training, pharmaceutical advertising, clinical decision‐making, and automation of clinical operations and workflow. However, there are growing concerns related to regulatory gaps, the spread of misinformation, security threats, patient and data privacy leaks, and widening health disparities gaps. These concerns are exacerbated by limited institutional infrastructure and limited AI literacy of clinicians and patients. Recent policy developments reflect efforts to guide responsible AI development and use. While progress has been made, the lack of standardized human oversight remains a critical gap, particularly as policies may not fully consider the challenges and complexities at institutional, societal, technical, and individual levels. Thus, herein, the Drug Information Practice and Research Network (DI PRN) of the American College of Clinical Pharmacy (ACCP) : (1) explores current and emerging multifaceted challenges, a call to action, and opportunities of AI integration in health care including examination of the regulatory, ethical, operational, and health equity implications; and (2) provides practical recommendations for responsible use of AI through DI PRN‐developed example case‐based approaches and best practices infographics to enhance AI literacy for diverse learners including clinicians, trainees, and patients. This DI PRN opinion paper highlights the importance of proactive governance frameworks and equips and empowers diverse learners with practical AI literacy tools to confidently engage with AI technologies in patient care.

Purpose: To compare stone clearance, stone-free status, and complications between patients undergoing ureteroscopy for renal stones using either Flexible and Navigable Ureteral Access Sheath (FANS) or the CVAC 2.0 system. Materials and Methods: A prospective study was completed on patients undergoing flexible ureteroscopy for renal stones at a single institution from March 2024 to December 2024. Subject demographics, intra-op data, volumetric and single-dimension stone clearance on non-contrast CT, and complications were compared. Stone-free rates (SFRs) using standardized cutoffs were compared. Pearson correlation analysis was performed to assess the relationship between preoperative stone volume and postoperative stone burden. Subanalysis was performed for patients with preoperative stone burden >1.5 cm. Results: A total of 123 cases (CVAC 2.0-36, FANS-87) were included, with 64 eligible for volumetric analysis. Preoperative stone volume was larger in the CVAC group vs FANS (1075 mm 3 vs 397 mm 3 ; p < 0.001). Absolute stone clearance was greater in the CVAC group (1016 mm 3 vs 392 mm 3 ; p < 0.001), whereas residual stone volume (4.1 mm 3 vs 15.0 mm 3 ; p = 0.55) and SFRs (90% vs 81%; p = 0.48) were similar. In individuals with >1.5 cm preoperative stone burden, relative stone clearance was greater with CVAC 2.0 (98.9% vs 95.1%; p = 0.026). Pearson correlation analysis revealed positive linear relationship between preoperative stone volume and residual stone volume for FANS, but not for CVAC 2.0. Conclusions: In this comparative study of FANS and CVAC 2.0, over 95% stone clearance was observed in both groups despite large initial stone burdens. In contrast to FANS, residual stone volumes with CVAC 2.0 did not increase significantly with increasing preoperative stone volumes.

BACKGROUND: Intracranial atherosclerosis (ICAS) is associated with an increased risk of early recurrent ischemic stroke. We evaluated whether biomarkers of impaired distal perfusion—specifically, anterior circulation borderzone infarct, and hypoperfusion mismatch volume—were associated with recurrent ischemic stroke within 90 days. METHODS: The BIORISK ICAS (Biomarkers and Recurrence Risk in Symptomatic Intracranial Atherosclerosis) is a multicenter retrospective international study (35 sites) that included hospitalized patients with symptomatic ICAS (50%–99% luminal stenosis of the intracranial vertebral, basilar, distal internal carotid, or proximal middle cerebral artery) from January 2019 to June 2024. The primary outcome was recurrent ischemic stroke in the territory of the symptomatic artery within 90 days. In the primary analysis, the exposure was an acute anterior circulation borderzone infarct. In secondary analysis of the subset with presentation within 72 hours of last known normal and perfusion imaging completed, the exposure of interest was prespecified as hypoperfusion mismatch volume at T max (time to maximum) threshold of 6 seconds, dichotomized at the Youden index. We performed multivariable Cox regression to test associations between exposure variables and the outcome, adjusting for clinically relevant variables and those associated with the outcome ( P <0.1). RESULTS: Of 2050 patients with symptomatic ICAS, 1737 (84.7%) presented within 72 hours of symptom onset, among whom 509 (29.3%) underwent perfusion imaging. The primary analysis included 1891 patients; 174 (9.2%) patients had recurrent ischemic stroke in the symptomatic arterial territory. In adjusted Cox regression models, there was an association between anterior circulation borderzone infarct and recurrent ischemic stroke at 90 days (adjusted hazard ratio, 1.40 [95% CI, 1.02–1.93]). In the perfusion imaging analysis, hypoperfusion mismatch of ≥10 mL was associated with recurrent ischemic stroke (adjusted hazard ratio, 1.83 [95% CI, 1.03–3.28]). CONCLUSIONS: Biomarkers of impaired distal perfusion, anterior circulation borderzone infarct, and hypoperfusion mismatch were associated with increased risk of recurrent ischemic stroke. These findings support the use of perfusion imaging in ICAS as well as future trials investigating early reperfusion in high-risk patients with ICAS.

Background Challenges in predicting which neoantigens mediate tumor rejection limit the efficacy of neoantigen vaccines to treat cancers, especially for cancers with a high mutational burden like cutaneous squamous cell carcinoma (cSCC). Only a small portion of neoantigens prioritized by current methods elicit effective T cell responses, demonstrating the critical need for improved criteria for the prediction of tumor-rejecting neoantigens. Methods Publicly available human cSCC datasets were used to assess the frequency of shared mutations between patients. A transplantable ultraviolet light-induced mouse model of cSCC was generated. The mutational signature and driver mutations in the mouse model were compared with human tumors. Neoantigens were prioritized in the mouse model, and tumor-rejecting neoantigens were identified through (enzyme-linked immunosorbent spot (ELISpot) and in vivo prophylactic vaccination. Binding of the neoantigens and corresponding wild-type peptides to major histocompatibility complex (MHC) class I was determined. Structural modeling of peptide:MHC complexes was performed to assess for changes in structural characteristics of the neoantigens relative to the wild-type peptides. Results A minority of human cSCC tumors shared neoantigens. The mouse cSCC model recapitulated the mutational signature and driver mutations found in human disease and was constrained by CD8 T cells. Two MHC class I neoantigens were identified in the mouse model that constrained cSCC growth. One tumor-rejecting neoantigen exhibited improved MHC binding, and the other had increased solvent accessibility of the mutated residue, compared with wild-type. Across known neoantigens that do not impact MHC binding, increased exposure of the mutated residue distinguished tumor-rejecting from non-immunogenic neoantigens. Conclusions Given the paucity of shared mutations, this work supports the need for personalized neoantigen vaccines in cSCC. To facilitate further discovery, we provide a clinically relevant mouse cSCC model with two defined neoantigens that mediate tumor rejection. Structural changes in the exposure of features that promote T cell receptor recognition defined tumor-rejecting neoantigens. Incorporation of structural modeling to predict changes in T cell receptor accessibility is anticipated to improve the selection of neoantigens for inclusion in personalized cancer vaccines.

Background: Massive weight loss after bariatric surgery (BS) often results in excess skin, leading to physical discomfort and impaired quality of life (QoL). Body contouring surgery (BCS) addresses these issues by restoring body image, improving function, and enhancing overall QoL, but its added value on patient-reported outcome measures (PROMs) remains underexplored. Methods: A systematic search of PubMed, Scopus, Embase, Web of Science, and Cochrane databases was conducted from inception to March of 2025. Studies comparing PROMs between patients undergoing BS alone and those undergoing BS + BCS were included. Retrieved studies were assessed using the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tool. Outcomes were pooled using random effects models. Results: Fifteen non-randomized studies involving 7339 patients were included (BS, 4339 [59.1%]; BS + BCS, 3000 [40.9%]). Patients undergoing BS + BCS had a significantly greater percentage of total weight loss (mean difference [MD], 4.40% [95% CI, 1.69, 7.10]; P < 0.01). BODY-Q improvements favored the BS + BCS group in body image, physical, psychological, sexual, and social function (MD, 16.07 [95% CI, 12.14, 20.0]; P < 0.01). Among patients receiving only BS, those desiring BCS reported lower body satisfaction (MD, −0.40 [95% CI, −0.70, −0.10]; P < 0.01) and lower appraisal of excess skin scores (standardized MD, −1.09 [95% CI, −1.83, −0.36]; P = 0.02) than those without desire for BCS. Conclusions: BCS after BS yields substantial improvements in overall QoL. These findings highlight the importance of BCS as a fundamental element of comprehensive postbariatric care that significantly enhances long-term patient satisfaction and drives durable multidimensional recovery.

Abstract BRCA2 mutations contribute to the pathogenesis and treatment sensitivity of a subset of ovarian, breast, prostate, and pancreatic cancers. When these cancers become therapy resistant, secondary mutations that restore the BRCA2 open reading frame are found in half the cases, but other causes of resistance remain incompletely understood. Here, we identified translational readthrough of a premature termination codon (PTC) as a cause of resistance to poly(ADP-ribose) polymerase inhibitors (PARPis) and cisplatin in cells derived from the BRCA2-mutated ovarian cancer line PEO1 by PARPi selection. Despite persistence of the signature 4965C &gt; G (p.Y1655X) BRCA2 mutation, low-level expression of full-length BRCA2 protein was detectable in these cells by immunoblotting and tandem mass spectrometry. Either BRCA2 knockdown or gene interruption 5′ or 3′ to the PTC restored treatment sensitivity, implicating BRCA2 in the resistance. Reporter assays demonstrated UAG-selective readthrough in the resistant clones but not parental cells. Moreover, custom searching of global proteomic data indicated readthrough of stop codons, particularly UAGs, in additional proteins in the resistant clones. Finally, multi-omic analysis identified multiple changes in the nonsense-mediated decay and termination machineries that favor readthrough. Accordingly, the present results identify PTC readthrough as a potential mechanism of drug resistance in cells with BRCA2 nonsense mutations.

OBJECTIVE To evaluate the impact of community paramedic (CP)-delivered, in-home diabetes self-management education and support (DSMES) for adults with poorly managed diabetes. RESEARCH DESIGN AND METHODS In a pragmatic, single-arm pilot trial, adults with HbA1c ≥9% and a recent emergency department or hospital visit received a 1-month CP-led DSMES intervention. Outcomes included HbA1c, health care engagement, and patient-reported satisfaction. RESULTS Seventy participants (median age 61 years, 50% rural, 84% with type 2 diabetes) completed the intervention. HbA1c declined from 9.8% to 8.2% at 4 months (P &lt; 0.001). Engagement with primary care, endocrinology, and DSMES improved. Satisfaction was high (mean rating 9 out of 10). CONCLUSIONS CP-led DSMES improved glycemic management and care engagement in underserved populations. This scalable model warrants further study.

98 Background: Prior authorization (PA) purports to control costs and ensure adherence to evidence-based guidelines but negatively impacts cancer care. Radiation oncology (RO) represents a minority of overall cancer spending yet bears a disproportionately high PA burden. Limited research exists on the effects of PA on patient outcomes and administrative workload within RO clinics. Methods: From 9/2024 to 10/2024, an online survey was open to U.S. members of the American Society for Radiation Oncology assessing experiences with PA including disposition (approval/denial/appeal including peer-to-peer [P2P] review) and perceived impact on patient care and administrative workload. Outcomes included treatment delays, changes from recommended treatment, and patient event including hospitalization, ED visits, permanent disability, or death. Descriptive statistics evaluated responses. Results: Of 736 responding radiation oncologists (16% response rate), 83% reported a rise in PA over the past three years, with 58% noting the burden has increased greatly. In the past year, 50% reported that more than half of their cases required PA, with a median approval rate of 75% and median overturn rate of 82% for denials. For more than half of their cases, nearly half of physicians (43%) noted that P2P was a futile effort to overturn PA denials due to insurance policies. Most (75%) reported that PA resulted in their practice needing to reallocate staff; 91% reported worsening burnout due to PA. P2P reviews were particularly burdensome, averaging 1.65 hours per week. A third (30%) reported that PA requirements had caused serious complications for their patients, including 7% who reported PA had contributed to patient death. Almost all (91%) reported PA-related treatment delays for some of their patients, with 58% indicating average delays of ≥5 days. Most (81%) reported that at times they had to use radiation techniques they considered less optimal due to PA, including 58% who were forced to deviate from national guidelines. The most common reasons for not appealing a PA denial were anticipated delays (73%), perceived futility based on prior PA experiences (62%), and administrative burden (45%). Conclusions: The administrative and clinical burdens associated with PA have significant implications for patient care, physician well-being, and healthcare resource allocation in RO. Treatment delays, compromised therapies, and adverse patient outcomes are commonly reported and underscore the need for PA reform to improve patient outcomes, reduce physician burnout, and improve efficiency.

Background: Chronic nonspecific low back pain (CNLBP) is a prevalent, disabling condition worldwide. Tuina, a traditional Chinese manual therapy, has shown potential benefits, but evidence remains limited. Objective: This study evaluated the effectiveness and safety of Tuina therapy in managing CNLBP in a U.S. population. Methods: A prospective, single-blind, randomized controlled trial was conducted at Mayo Clinic Rochester campus (February 2020-April 2024). 204 participants with CNLBP were randomized into 3 groups: Tuina (N = 68), physical therapy (N = 68), or a combination of both (N = 68). Each group received 6 treatments over 2 months. The primary outcome was pain intensity (VAS); secondary outcomes included disability (ODI), quality of life (SF-36), and adverse events. Additionally, participants completed a satisfaction survey at the end of the trial. Research Electronic Data Capture (REDCap) was used for survey data collection. Data was assessed by analysis of variance (ANOVA) for the multiple repeated measurements, Kruskal-Wallis tests, while Chi-square tests, and Bonferroni correction in SAS software. Results: 185 subjects completed the study. Significant decreases in VAS, ODI, and SF-36 Overall Physical scores were found from baseline, to post treatment and follow-up in all groups ( P < .05), while there were no significant differences in VAS, ODI, or SF-36 outcomes between the Tuina group and the other 2 groups. There were 4 adverse events observed in the trial, 1 in the Physical therapy group and 3 in the Mixed group. Only 1 transient low back pain after Tuina therapy was observed in the Mixed group but did not require treatment. The high percentage of patients who received the Tuina program was extremely helpful (n = 94/126, 77.0%). The willingness to recommend was significantly higher for Tuina compared to physical therapy (Mixed group [N = 59/62, 95.2%], Tuina group [N = 57/64, 91.9%], and physical therapy group [N = 31/59, 59.6%] ( P < .05). Conclusion: Tuina therapy showed comparable benefits to physical therapy and combined treatment of both in improving pain, function, and quality of life in patients with CNLBP. With high patient satisfaction and a favorable safety profile, Tuina appears to be a safe and acceptable non-invasive treatment option. Further studies are needed to validate these findings in the future.
