Purpose: Compared with white-light cystoscopy (WLC), blue-light cystoscopy (BLC) enhances detection of non–muscle-invasive bladder cancer (NMIBC), especially carcinoma in situ (CIS). However, its effects on health care resource utilization and cost burden have not been fully elucidated. This study assessed the economic implications of BLC vs WLC. Materials and Methods: We conducted a retrospective cohort analysis with claims data from the Optum Research Database between June 2011 and May 2023. Patients who underwent BLC or WLC were identified, and white-light patients were matched 6:1 to blue-light patients by index year and time between bladder cancer diagnosis and cystoscopy. Inverse probability of treatment weighting was used to adjust for baseline differences. Health care resource utilization and total and bladder cancer–specific costs were calculated on a per-patient-per-month basis. Results: The final cohort included 794 blue-light and 4764 white-light patients. Before weighting, claims coded for CIS were more frequent in blue-light patients (19.6% vs 8.8%; P < .001). Blue-light patients underwent more upper-tract imaging (71.8% vs 57.8%; P < .001), BCG (24.2% vs 15.8%; P < .001), and biomarker testing (65.0% vs 34.9%; P < .001). After weighting, blue-light patients had a higher mean number of bladder cancer–related ambulatory visits per month (1.3 vs 1.0; P = .004). However, neither all-cause health care resource utilization (3.47 vs 3.21; P = .11) nor total cost ($2987.93 vs $2886.16, per patient per month, P = .65) differed significantly between cohorts. Conclusions: BLC is associated with greater health care resource utilization for NMIBC without significantly elevating health care costs, suggesting that enhanced diagnostic strategies can be implemented without added financial burden in real-world practice.

Abstract Introduction: Erythromelalgia is a descriptive term for burning pain and erythema in distal extremities, often worsened by heat and improved by cold. Inherited erythromelalgia has been primarily linked to gain-of-function variants in SCN9A , encoding voltage-gated sodium channel NaV1.7. However, approximately 65% to 85% of patients with erythromelalgia do not have pathogenic SCN9A variants. Objectives: The objective of this study was to uncover and assess gene variants potentially associated with pediatric-onset erythromelalgia. Methods: With IRB approval and informed consent, probands and families with erythromelalgia underwent next-generation sequencing. A list of genes of interest was produced based on Mendelian inheritance models. Selected gene candidates were assessed using the Sequence Kernel Association Test-Optimal (SKAT-O). Results: Sixty-two probands with erythromelalgia and their relatives were included in Mendelian analysis, which identified variants in PR domain zinc finger protein 12 ( PRDM12 ) and dihydropyrimidinase-like protein 2 ( DPYSL2 ). In a targeted 12-gene rare-variant set analysis using SKAT-O, zinc finger homeobox protein 2 ( ZFHX2 ) showed evidence of association ( P = 6.9 × 10 −4 ), surpassing Bonferroni correction for 12 tests (α = 4.17 × 10 −3 ), whereas KIF1B showed only a nominal association signal ( P = 0.03) that did not survive multiple-testing correction. Conclusion: Genes associated with both increased and decreased pain sensitivity are of considerable interest for elucidating pain mechanisms and analgesic development. As rare variants in PRDM12 and DPYSL2 were identified in a pediatric erythromelalgia cohort and a gene-based rare-variant association signal for ZFHX2 was identified, replication and functional validation are needed.

Objective To compare perioperative outcomes, complications, imaging utilization, and device management following posterior vault distraction osteogenesis (PVDO) and spring-mediated cranioplasty (SMC) for multisutural craniosynostosis. Design Retrospective cohort study. Setting Single pediatric tertiary care center. Patients, Participants Twenty-three patients with multisutural craniosynostosis treated between 2017 and 2025 (PVDO, n = 18; SMC, n = 5). Interventions PVDO or SMC. Main Outcome Measure(s) Time to device removal, imaging utilization, reoperations, readmissions, device-related complications, revision surgeries, wound infections, and absolute intracranial volume change. Results PVDO was associated with earlier device removal than SMC (78.7 ± 22.1 vs. 133.0 ± 27.4 days; P = .0015) but greater postoperative imaging utilization during the first year (5.33 ± 1.28 vs. 2.80 ± 1.64 studies; P = .01). Rates of reoperation (22.2% vs. 0%), readmission (22.2% vs. 40.0%), device-related complications (11.1% vs. 0%), revision surgery (16.7% vs. 0%), and wound infection (22.2% vs. 20.0%) did not differ significantly (all P ≥ .50). Preoperative imaging utilization and postoperative intracranial volume gain were comparable between groups. Conclusions PVDO and SMC demonstrated similar safety profiles and intracranial volume expansion in patients with multisutural craniosynostosis. Compared with SMC, PVDO enabled earlier device removal but required increased postoperative imaging. These findings may inform operative planning, postoperative surveillance, and family counseling. Larger, multicenter studies with longer follow-up are needed to evaluate long-term outcomes.

Scientific evidence regarding AKI and acute kidney care has advanced in recent years. However, a knowledge gap remains on the implementation of these evidence-based practices (EBPs) into clinical care. Implementation science (IS) is focused on ensuring that this knowledge is translated in an effective, efficient and sustainable fashion. Objectives: 1) Define the current status of IS; 2) Define a roadmap for accelerating IS with a focus on patient/care partner advocacy, digital tool application, social determinants of health, and resource-limited settings; and 3) Develop a robust and broad research agenda incorporating IS methodology into the programs. Evidence Review: ADQI XXXV was conducted through a modified Delphi process with virtual meetings preceding an in-person meeting. Five workgroups were determined a priori to focus on 1) IS definitions and methods applicable to AKI and acute kidney care; 2) IS literature in AKI and acute kidney care; 3) Innovations in IS to accelerate the adoption, adherence to, and sustainment of EBPs in AKI and acute kidney care; 4) IS methods in resource-limited settings; and 5) Recommendations to identify and evaluate EBPs that are ready for implementation or de-implementation. Prior to the in-person meeting, each workgroup met virtually to review the literature and develop framework questions to address their objectives. During the two-day in person meeting, through iterative discussions, questions and supporting statements were finalized. These questions and statements were agreed upon through voting to achieve consensus, defined as agreement of ≥80%. Conclusions and Relevance: We report a structured multidisciplinary consensus for defining the role of IS in AKI and acute kidney care. Future programs should address these consensus questions and apply these statements along with IS methodology in the translation of science into clinical practice and the implementation/de-implementation of EBPs in clinical care.

Importance Although adding immune checkpoint inhibitors to neoadjuvant chemotherapy improves outcomes in high-risk early-stage breast cancer, opportunities remain to further enhance response. Dual checkpoint blockade offers a potential strategy to further enhance efficacy. Objective To evaluate the combination of anti−programmed cell death 1 protein (PD-1) cemiplimab and anti−lymphocyte activation gene 3 (LAG-3) added to neoadjuvant therapy in ERBB2 -negative early-stage, high-risk breast cancer. Design, Setting, and Participants The I-SPY2 (Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging and Molecular Analysis 2) is an ongoing randomized clinical platform trial being conducted at multiple US clinical sites including patients with early-stage (II or III) ERBB2 -negative, high-risk breast cancer. Participants, continuously enrolled since 2010, were adaptively randomized from February 2, 2020, to December 9, 2021, to one of several experimental neoadjuvant therapies or control groups based on receptor subtypes defined by hormone receptor (HR), ERBB2 status, and MammaPrint (Agendia Inc) molecular risk, categorized as high (MP1) or ultrahigh (MP2). Data were analyzed from January 1, 2022, to August 5, 2025. Interventions Both groups received weekly paclitaxel for 12 weeks, then doxorubicin and cyclophosphamide followed by surgery; concomitant with paclitaxel, the intervention group also received 4 doses of cemiplimab and fianlimab (PCF) every 3 weeks. Main Outcomes and Measures Pathologic complete response (pCR). Treatments graduated when they achieved 85% bayesian probability of success in a subtype-specific phase 3 trial. Pathway-specific biomarkers were assessed for response prediction. Results A total of 78 participants (mean [SD] age, 47 [39-54] years) were randomized to the intervention group, with 350 participants (mean [SD] age, 48 [39-57] years) randomized to the historical control population. PCF graduated in all clinical signatures, with pCR rates vs control of 44% (95% CI, 34%-53%) vs 21% (95% CI, 17%-25%) in all ERBB2 , 53% (95% CI, 39%-67%) vs 29% (95% CI, 22%-36%) in triple-negative, and 36% (95% CI, 23%-49%) vs 14% (95% CI, 9%-19%) in HR-positive and ERBB2 -negative disease. Among the total participants, 16 (21%) experienced adrenal insufficiency, including hypophysitis (11% grade 3 or 4), mostly occurring after immunotherapy completion. PCF was found to be highly effective in the subset of patients with immune signature positive status (ImPrint positive). Conclusions and Relevance In this randomized clinical trial, the combination of PD-1 and anti−LAG-3 inhibition with standard NAC was effective in early-stage ERBB2 -negative breast cancer, particularly in patients displaying a positive ImPrint immune signature. These results warrant further definitive trials. Trial Registration ClinicalTrials.gov Identifier: NCT01042379

Importance Elevated low-density lipoprotein cholesterol (LDL-C) is a modifiable risk factor for cardiovascular disease, the leading cause of premature death worldwide. Assessing the LDL-C–related burden is critical for guiding prevention and treatment strategies. Objectives To estimate the global, regional, and national burden of ischemic heart disease and ischemic stroke attributable to elevated LDL-C (relative to 35-54 mg/dL) from 1990 to 2023 and to quantify the contributions of population growth, aging, risk-deleted burden, and exposure changes to burden trends. Design, Setting, and Population This comparative risk assessment, part of the Global Burden of Disease Study 2023, estimated population-level LDL-C exposure and associated health loss in 204 countries and territories. Mean LDL-C levels were estimated using spatiotemporal gaussian process regression based on 806 studies across 161 countries. Relative risks were derived from meta-analyses of 38 randomized clinical trials. Population-attributable fractions for deaths and disability-adjusted life-years (DALYs) were estimated by age and sex for adults aged 25 years or older from 1990 to 2023, with 95% uncertainty intervals. Exposure Population-level LDL-C concentrations. Main Outcomes and Measures Population-attributable fractions, counts, and rates (all ages and age standardized per 100 000) of LDL-C–attributable deaths and DALYs from ischemic heart disease and ischemic stroke, with uncertainty intervals. Results In 2023, elevated LDL-C accounted for 3.6 million deaths (95% uncertainty interval, 2.2-5.4 million; 6.0% of global mortality) and 90.7 million DALYs (95% uncertainty interval, 58.9-123.3 million; 3.2% of DALYs). Although global all-ages rates remained stable, age-standardized death and DALY rates decreased by 45.6% and 39.5%, respectively, since 1990. In 2023, age-standardized LDL-C–attributable DALY rates were highest in Eastern Europe and lowest in high-income Asia-Pacific. One-third of the global LDL-C burden occurred in India and China. Population growth and aging drove the increasing burden, with notable regional disparities in LDL-C exposure and risk-deleted DALY rates shifting toward middle-sociodemographic settings. Conclusions and Relevance Despite declining age-standardized rates, the absolute LDL-C burden has increased since 1990 due to demographic changes and has shifted toward middle-sociodemographic countries. Measurement and surveillance gaps persist. Strengthened prevention, diagnosis, and treatment access strategies are essential to mitigate the health burden of LDL-C.

ABSTRACT Background Post‐transplant malignancy is a major determinant of long‐term outcomes after solid organ transplantation. Whether simultaneous pancreas–kidney (SPK) transplantation confers a differential post‐transplant cancer risk compared With kidney transplantation alone (KA) remains uncertain. Methods We conducted a retrospective propensity score–matched cohort study of adult transplant recipients at three Mayo Clinic sites between 2001 and 2017. SPK recipients ( n = 484) were matched 1:1 with KA recipients using propensity scores. The primary outcome was post‐transplant cancer incidence analyzed using Fine–Gray competing risks regression with death as a competing event. Standardized incidence ratios (SIRs) were calculated relative to the US general population. Cox proportional hazards models with cancer modeled as a time‐varying covariate evaluated associations with mortality and death‐censored graft failure. Results Over a median follow‐up of 10 years, overall cancer incidence was similar between SPK and KA recipients (subdistribution hazard ratio [sHR] 0.80, 95% CI 0.63–1.02; p = 0.07). The observed trend toward lower cancer incidence in SPK recipients was driven by a lower incidence of non‐melanoma skin cancer (NMSC) (sHR 0.72, 95% CI 0.53–0.97; p = 0.03), which was attenuated after age adjustment (sHR 0.76, p = 0.07). Incidence of other malignancies did not differ between groups. Compared with the US general population, cancer risk excluding NMSC was approximately twofold higher in both cohorts (SIR 2.18 for SPK vs. 2.23 for KA). Incident malignancy was strongly associated with increased mortality (HR 3.40 in KA and 2.07 in SPK) but not with a statistically significant increase in graft failure. Conclusions In this propensity score–matched cohort study, overall post‐transplant malignancy incidence was comparable between SPK and KA recipients. Both groups experienced substantially elevated cancer risk relative to the general population, and incident malignancy was strongly associated with mortality. These findings suggest that malignancy risk is driven primarily by shared immunologic and demographic factors rather than transplant type.

ABSTRACT Beta‐lactam antibiotics (beta‐lactams) are first‐line treatments for most major infectious syndromes in acutely ill patients, with in vitro activity against common pathogens, demonstrated efficacy in trials, and a perceived low risk of adverse effects. The current dosing approach, informed by population‐level data, tends to be simplistically reduced to a “one size fits all” dosing method which only accounts for body weight (i.e., in pediatrics) and end organ function to estimate drug clearance (e.g., estimated glomerular filtration rate); this approach results in substantial variability in observed serum concentrations in acutely ill patients, which can compromise real‐world effectiveness and safety. Beta‐lactam dose individualization, therefore, defined as a dosing regimen for one patient informed by measured concentrations from that patient, has been recommended in international clinical guidelines. Comprehensive guidance on best practices for beta‐lactam dose individualization is lacking. To address this knowledge gap and develop guidance, a multidisciplinary panel of international experts was assembled from the disciplines of infectious diseases, critical care, pharmacometrics, and laboratory medicine, representing both adults and pediatrics. The panel systematically evaluated the literature, using the GRADE approach where feasible, to address broad thematic questions pertaining to whether beta‐lactam dose individualization should be pursued, for what indications beta‐lactam dose individualization is warranted, and the most critical considerations and best practices for implementation of beta‐lactam individualization. The resultant consensus recommendations will equip healthcare professionals caring for acutely ill patients treated with beta‐lactam therapy with the evidence and tools necessary to guide optimal use of beta‐lactam dose individualization.

Background: We had a large-scale measles exposure event affecting 626 patients. Management of exposed patients was urgent, involving quarantine, post-exposure prophylaxis (PEP), and symptom monitoring on a case-by-case basis. Cases were initially tracked and managed using a combination of multiple spreadsheets amongst stakeholders as well as lists within the electronic health record (EHR). Using shared spreadsheets and lists created significant challenges with maintaining and editing multiple copies and updating workbooks simultaneously. Methods: Infection Prevention and Control (IPAC) worked with primary care personnel and EHR developers to create a shared registry that would prioritize communication and follow-up for exposed patients based on age and immunity. Patients are initially added to the shared registry within the EHR by reviewing non-registry reports and tagging patients, identified using exposure timeframes that overlapped with the index measles cases, in a manner that transferred them to the shared registry. From this registry, measles, mumps, and rubella vaccine status can be confirmed, immune status can be identified, and criteria for PEP assigned. High-risk patients are then contacted with recommendations from IPAC and primary care. Communication and follow-up are tracked directly within the shared registry to ensure appropriate patient management. The exposure management registry is further leveraged throughout the measles outbreak timeframe by allowing real-time monitoring of patients that require additional precautions or guidance related to their exposure. Result: The shared registry enhanced documentation accuracy and transparency between stakeholders. It led to availability of real-time status of exposed patients for the duration of the measles outbreak timeframe. Overall, the registry enabled time-sensitive patient communication to all exposed patients and rapid identification of those who needed PEP. Communication could happen rapidly and seamlessly between care teams within the organization, and the necessary information could be shared quickly with public health authorities as required. Conclusion: Large scale exposures are a challenge to manage and ensure appropriate action and communication occurs. Errors can be prevented by having a single shared exposure management registry. A registry enables care teams to quickly identify and prioritize patients for measles follow-up, communication, PEP, and ongoing management across outbreak timeframes. This process reduces both time and operational burdens of exposure follow-up tracking outside of the EHR.

Background: Penile inversion vaginoplasty (PIV) is a common gender-affirming procedure for transgender women, but validated, transgender-specific patient-reported outcomes remain limited. This study evaluated long-term outcomes after PIV using the Post-Affirming Surgery Form and Function Individual Reporting Measure (AFFIRM), a validated instrument assessing appearance, urologic, and gynecologic domains. Methods: We conducted a single-institution retrospective cohort with a cross-sectional, anonymous AFFIRM survey distributed in 2024. Demographics, perioperative outcomes, and complications were obtained by chart review. AFFIRM domain scores, reported on a 0–200 scale with lower scores indicating better outcomes, were analyzed descriptively. Results: Of 193 eligible patients who underwent PIV between 2017 and 2023, surveys were delivered to 186 patients, and 47.8% responded. Median age at surgery was 34.3 years (interquartile range 26.1–49.1), with a median follow-up time of 50.0 months. Most respondents reported high satisfaction with genital appearance, and 90% strongly agreed their anatomy aligned with gender identity. Clitoral sensation was reported by 93%, most commonly as pleasurable. Urologic symptoms were generally minimally bothersome; although 59% reported a misdirected urine stream, mean bother score was low (1.64 ± 1.77). Vaginal dryness and dyspareunia were reported by 43% and 44%, respectively, with 27% describing symptoms as bothersome. Major complications occurred in 13.9% and revision surgery in 34.2%, most commonly for stenosis or depth concerns (13.5%). Conclusions: AFFIRM captured meaningful, transgender-specific, long-term outcomes after PIV, complementing traditional surgical metrics and identifying opportunities to improve preoperative counseling, surgical refinement, and postoperative management of vaginal dryness and urinary symptoms.
