Background Artificial intelligence (AI)-generated text to video is emerging in medical education, but its effectiveness, accuracy and safety remain uncertain. We aimed to synthesise empirical studies evaluating these tools in learner or patient education. Methods A comprehensive search was conducted in MEDLINE/PubMed, Google Scholar, Scopus, Cochrane Review and Web of Science for studies published up to January 2025. Eligible studies evaluated AI-generated text to video for medical or patient education, reporting both quantitative and qualitative outcomes. Two reviewers screened and extracted data. The review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results Out of 103 identified studies, five studies met the inclusion criteria: four evaluated patient education and one evaluated physician training. Clinical areas were ophthalmology (2/5), plastic surgery (1/5), dysphagia rehabilitation (1/5) and neurosurgical training (1/5). In ophthalmology, control materials outperformed AI-generated videos on image/script accuracy (p<0.005), with similar script-image alignment. In dysphagia rehabilitation, a randomised trial reported improvements in swallowing function and related outcomes with an AI-assisted video game intervention (p<0.001). A plastic surgery study reported greater user preference for a video avatar tool compared with a text chatbot (63.5% vs 28.1%). Across the reviewed studies, samples were small and CIs were rarely reported. Outcome measures were heterogeneous, and meta-analysis was not feasible. Conclusion AI-generated videos can enhance engagement or selected outcomes in certain contexts, yet concerns about accuracy and inconsistent measurement persist. Current evidence is sparse and mixed. Currently, these tools can complement, rather than replace, standard resources until non-inferiority is demonstrated for the prespecified primary outcomes.

Background Bowel obstruction in the setting of peritoneal metastases is a complex clinical situation. Evidence for operative intervention in this setting remains unclear. This study aimed to compare outcomes between patients with bowel obstruction and peritoneal metastases who underwent operative intervention vs those who underwent conservative management. Methods This was a retrospective single center study of all patients that were consulted on by the Division of Colon and Rectal Surgery in the 6-year period between January 1st 2019 and December 31st 2024 for the management of bowel obstruction in the setting of peritoneal metastases. The study compared patients who underwent operative intervention vs those who underwent conservative management. The primary outcome measures were ability to tolerate solid food at discharge, median obstruction free survival, and median overall survival. Results A total of 100 patients were diagnosed with bowel obstruction in the setting of peritoneal carcinomatosis. 47 patients underwent operative intervention and 53 underwent non-operative management. Those who underwent operative intervention were more likely to tolerate solid food at discharge (78.72% vs 47.17%, P < 0.01) and had a longer median obstruction free survival (593 days vs 147 days, P = 0.01). No difference was identified in overall survival (133 days vs 99 days, P = 0.49). Conclusions Bowel obstruction in the setting of peritoneal metastases is a complex situation that requires a personalized and pragmatic approach for each patient. Selecting those who may benefit from operative intervention can be challenging, however, there are subsets of patients for whom surgical management may be offered with acceptable outcomes.

ABSTRACT Introduction Although covalent Bruton's tyrosine kinase inhibitors (cBTKis) have transformed treatment of chronic lymphocytic leukemia and small lymphocytic leukemia (CLL/SLL), cBTKi‐related cardiotoxicity is a known side effect. This real‐world study evaluated incident cardiovascular adverse events (CVAE), healthcare resource utilization (HCRU), and costs among patients with CLL/SLL receiving cBTKis. Methods Adult patients with CLL/SLL who initiated ibrutinib or acalabrutinib treatment (index date) between 2020 and 2023 were identified using US claims data and followed up to 36 months post‐index. Incident CVAEs (not present pre‐index) were assessed during cBTKi treatment and patients were stratified by CVAE status. HCRU and costs were evaluated per 1000 patient‐months (PPPM). Results Overall, 2069 patients were identified (mean age of 73.7 ± 9.1 years, 40.4% female) with a mean treatment‐specific observation period of 11.4 ± 9.5 months. At least one incident CVAE was observed in 442 (21.4%) patients. The incidence rate was 21.6 PPPM for hypertension, 8.9 PPPM for atrial fibrillation, 8.6 PPPM for ventricular arrhythmias, and 8.3 PPPM for atrial flutter. Patients with incident CVAEs had significantly more total medical service days PPPM (4334 vs. 3138, p < 0.001), primarily driven by increased inpatient (690 vs. 230), outpatient (2798 vs. 2425), other visit (662 vs. 375), and ER days (184 vs. 109) than those without CVAEs. Total healthcare costs (PPPM) were substantially higher for patients with incident CVAEs ($20,250,560 vs. $17,413,460, p < 0.001) mainly due to higher inpatient ($3,417,948 vs. $915,839, p < 0.001), outpatient ($2,415,060 vs. $1,769,628, p < 0.01), and ER costs ($186,820 vs. $87,585, p < 0.001). Conclusions The observed class‐effect of high CVAEs with cBTKis underscores the unmet need for safer, more selective agents for CLL/SLL treatment. The HCRU and economic burden remain high for CLL/SLL, especially among patients experiencing CVAEs during cBTKi treatment. These findings emphasize the importance of optimizing clinical management to reduce CVAE risk and downstream impacts on HCRU and costs.

Multiplex immunofluorescence and immunohistochemistry (mIF/IHC) are increasingly employed antibody-based technologies that use tissue sparingly and facilitate the detection of co-localized or neighboring biomarkers. Specifically, these platforms enable spatial analyses of the tumor microenvironment as well as extended applications, for example, describing normal tissue anatomy, autoimmunity, infectious diseases, etc. mIF/IHC has greatly enhanced biomarker discovery efforts, and a growing number of studies suggest superiority to traditional IHC. Standardization of staining approaches, reporting of image analysis strategies and resultant data is critical for facilitating cross-study comparisons, validation, deployment, and generalization of findings. To address this challenge, The Society for Immunotherapy of Cancer (SITC) previously published two articles providing best practice guidelines for mIF/IHC staining, image analysis, and data sharing. Here, SITC convened stakeholders to develop the third article in the series, a consensus checklist for scientific reporting of mIF/IHC data to support and complement the best practice guidelines. The checklist includes critical components of mIF/IHC applications to be defined within publications such as detailed descriptions of analytical validation; image acquisition, selection, and registration methods; and cell clustering and spatial analysis strategies, amongst others. Such information will help with data reproducibility and comparison across studies towards future drug and assay development.

ABSTRACT Background Isolated chromosome 5/5q losses (–5/5q) without TP53 mutations are associated with favorable outcomes in myeloid neoplasms (MN) with <5% blasts. However, the clinical implication of concurrent −5/5q and TP53 aberrations in MN with ≥5% blasts is poorly understood. Methods Patients with TP53 ‐mutated MN carrying ≥5% blasts assessing the prognostic impact of ‐5/5q on 24‐month overall survival (OS24) were examined. Results Of 587 patients, 515 (88%) exhibited −5/5q overwhelmingly in the context of a complex karyotype (98.3% vs. 61.1% complex karyotype without −5/5q; p < .0001) and multihit TP53 allelic state (88.3% vs. 56.9%; p < .0001). Proportions of patients with blasts ≥20% were comparable between groups with and without −5/5q; p = 0.26. Notably, patients with −5/5q exhibited significantly fewer coalterations; p < .0001. Looking at outcomes, presence of −5/5q was associated with shorter median 24‐month overall survival (7.8 months vs. 11.2 months; p Log‐rank = .012), an effect restricted to subgroups with blasts <20% ( p = .039; N = 163), absent −7/7q ( p = .007; N = 225), or WHO5‐defined single hit allelic state ( p = 0.030; N = 91). Importantly, −5/5q retained independent adverse prognostic significance regardless of TP53 allelic state in a multivariable model. Furthermore, among the subset of 75 (13%) patients undergoing allogeneic stem cell transplantation, −5/5q predicted significantly shorter median 5‐year posttransplant survival (16.2 months vs. median not reached; p Log‐rank = .009). Conclusions These findings emphasize the independent prognostic relevance of chromosome 5/5q losses underscoring the clinical relevance of cytogenetic testing for −5/5q even in this high‐risk cohort.

Introduction Despite the identification of multiple susceptibility loci by genome-wide association studies (GWAS), considerable chronic obstructive pulmonary disease (COPD) heritability remains unexplained. Aim To identify interaction networks of airway epithelial cell DNA methylation in COPD and further explore potential correlations with airway bacterial composition, as potentially collective regulators of biological pathways influencing COPD severity. Methods Using DNA isolated from bronchial airway brushings of 67 ever-smokers (>20 pack-years) from the SubPopulations and InteRmediate Outcomes Measures in COPD Study (SPIROMICS), we assessed proportion of DNA methylation (β) by epigenome-wide association study (EWAS) and examined associations of differentially methylated CpG probes (DMPs) with risk for moderate-to-severe COPD (N=34) versus absent or mild COPD (N=33). We tested co-methylation modules generated by Weighted Correlation Network Analyses (WGCNA) for associations with moderate-to-severe COPD and with bacterial genus-level relative abundances (16S rRNA sequencing). Results EWAS-identified nominally significant DMPs enriched for lung function GWAS loci. Eigengenes in six WGCNA modules were associated with moderate-to-severe COPD (false discovery rate <0.05). Four of those modules were enriched for forced expiratory volume in 1 s/forced vital capacity GWAS loci, and five overlapped with DMPs from EWAS. Overlapping CpG loci in three COPD-associated modules were adjacent to mucin genes; one had 10 genes highly ranked by connectivity with MUC5B, including important pathway genes: B3GNT6 , DGKI and ITGA8 . CpGs in an independent COPD-associated module showed the most correlations with Rothia , with directionality suggestive of negative associations with moderate-severe COPD. Conclusions Bronchial epithelial DNA methylation modules enriched for lung function GWAS loci associate with COPD severity in SPIROMICS. Potential module relationships to bronchial bacterial composition require further validation.

Objective The objective of the study was to determine risk factors for relapse of antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) after reinduction of remission with rituximab and discontinuation of maintenance therapy. Methods This is a post hoc analysis of the RITAZAREM clinical trial. Patients aged 15 years or older with AAV and a positive test for anti–proteinase‐3 or anti‐myeloperoxidase‐ANCA who achieved remission after reinduction with rituximab and glucocorticoids were randomized at month 4 to receive continued rituximab or azathioprine for a maintenance period up to 24 months, followed by observation until relapse or up to 48 months. Generalized estimating equations logistic regression identified baseline and time‐varying risk factors for relapse by the next visit for the two study phases: maintenance (months 4–24) and off‐treatment (months 24–48). Results Among 170 patients (median [interquartile range] age 59 [48–68] years, disease duration 5 [2–10] years), 99 relapses occurred (46 during maintenance). During maintenance, musculoskeletal involvement (odds ratio [OR]: 2.8, 95% confidence interval [CI]: 1.1–7.2; P = 0.03) and higher patient global assessment (OR: 1.1, 95% CI: 1.0–1.2; P = 0.04) were associated with relapse. During the off‐treatment phase, presence of CD19 + B cells (OR: 2.5, 95% CI: 1.2–5.1; P = 0.01) and reappearance of ANCA (OR: 3.2, 95% CI: 1.3–7.7; P = 0.01) were each associated with higher relapse risk. Multivariable analysis identified markers of inflammation (changes in platelets, white blood cells, and IgA) associated with relapse. Conclusion Risk factors for relapse in AAV vary by treatment phase. Monitoring markers of inflammation and immune reconstitution may identify patients at risk for relapse, particularly after treatment withdrawal.

Importance Molecular analyses of biospecimens collected from study participants are essential for identifying biomarkers that can tailor treatments to specific subsets of patients who are most likely to benefit. Sharing of data and biospecimens from clinical trials enables personalized, patient-centric use of cancer therapies and accelerates the development of new treatments. Objective To describe obstacles to sharing data and biospecimens and to propose strategies to enhance access and collaboration. Evidence Review This is a Special Communication authored by 53 academic investigators and patient representatives from the breast cancer community with extensive experience in conducting clinical and translational research. The article also evaluates the impact of biomarker research on specifying responsive subpopulations in the 29 registrational clinical trials that have led to approval of a new drug for treatment of breast cancer between 2017 and 2024. Findings Clinical trial participants are increasingly asked to provide tissue and/or body fluid biospecimens for biomarker research that is typically controlled by the sponsoring pharmaceutical company, but published biomarker studies are rare. Among 29 breast cancer registrational studies reported in the past 8 years, none resulted in biomarker research that restricted a drug’s approved indication. Herein, strategies to maximize the value of clinical data and biospecimens contributed by participants are proposed, thereby supporting the shared goals of the pharmaceutical industry and academia to improve patient care. These strategies include (1) establishing coleadership structures involving academia and patients in clinical trial design and conduct, (2) ensuring that informed consent forms state that data and biospecimens will be shared with academia for future research, (3) requiring the sharing of clinical data as a condition for regulatory approval, and (4) enabling access to biospecimens and translational research data for independent studies on biomarkers that may indicate drug efficacy and toxicity. Conclusions and Relevance Data and biospecimen sharing from registrational trials has been suboptimal. Improving clinical data, biospecimens, and biospecimens’ related data sharing requires concrete actions and a multidimensional stakeholder approach to accelerate the impact of clinical cancer research on the quality of patient care.

Living liver donation is a critical component for addressing organ shortage and improving outcomes for patients with end-stage liver disease. As the prevalence of living donor liver transplantation (LDLT) increases worldwide, understanding and optimizing long-term donor health is paramount. The 2025 International Liver Transplantation Society and International Living Donor Liver Transplantation Society (ILTS-iLDLT) Consensus Conference convened experts in the field of liver transplantation to establish evidence-based guidelines focused on the long-term medical, psychological, and social considerations following living liver donation. The aim of this working group was to integrate current evidence and expert consensus on donor follow-up protocols, risk assessment, and management strategies to promote long-term donor health, quality of life, and living liver donor programs globally to safeguard the welfare of this unique population.
