Abstract Background These recommendations provide guidance on the optimal timing for transitioning from intravenous to oral antibiotics in patients with complicated urinary tract infection (cUTI), especially in presence of associated Gram-negative bacteremia. Methods The panel's recommendations are based upon evidence derived from systematic literature reviews which focused on comparative benefits and harms of transitioning to oral therapy versus continuing parenteral therapy of the total duration of treatment, including publications since 2000. These recommendations adhere to a standardized methodology for rating the certainty of evidence and strength of recommendation according to the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. Results The guidelines panel suggests transitioning to oral antibiotics in patients with cUTI who are clinically improving, able to take medication, and for whom an effective oral option is available, rather than continuing parenteral therapy for the remaining treatment duration, regardless of the presence of associated Gram-negative bacteremia. An effective oral option needs to be active against the causative pathogen and achieve therapeutic levels in the urine and relevant tissue. Conclusions Parenteral and oral antibiotics used to complete treatment courses for cUTI provide similar efficacy and adverse events, especially in the context of shorter duration of therapy. This recommendation places a high value on reducing avoidable intravenous catheter-related adverse events, costs, and resources, as well as taking into account practical aspects of antibiotic administration.

Abstract Background These recommendations provide guidance on the optimal duration of antibiotics in patients with complicated urinary tract infection (cUTI), especially in presence of associated Gram-negative bacteremia. Methods The panel's recommendations are based upon evidence derived from systematic literature reviews which focused on comparative benefits and harms of shorter (5–7 days) vs prolonged (10–14 days) duration of antibiotics, including publications since 2000. These recommendations adhere to a standardized methodology for rating the certainty of evidence and strength of recommendation according to the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. Results The guidelines panel suggests that patients with cUTI who are improving on effective therapy can be treated with shorter duration of antimicrobials (either 5–7 days of a fluoroquinolone or 7 days of a non-fluoroquinolone) rather than longer courses of antibiotics, regardless of the presence of associated Gram-negative bacteremia. An effective antimicrobial agent achieves therapeutic levels in the urine and relevant tissue and is active against the causative pathogen. However, men with febrile UTI in whom acute bacterial prostatitis is suspected may benefit from a longer treatment duration (10–14 days), and a short courses of oral beta lactams may require higher doses for efficacy. Conclusions Shorter durations of antibiotics for cUTI provide similar efficacy as longer courses, except in men with febrile UTI in whom acute bacterial prostatitis is suspected. This recommendation places a high value on antibiotic stewardship considerations as well as reducing the burden of antimicrobial administration from a healthcare perspective and reducing the burden of taking antibiotics from a patient perspective.

Abstract Background These recommendations address the empiric choice of antibiotics in suspected complicated urinary tract infection (cUTI). Issues to balance include the need for appropriate initial empiric antimicrobial therapy, the patient's severity of illness, and antimicrobial stewardship concerns. Methods The panel's recommendations are based upon evidence derived from systematic literature reviews that focused on comparative benefits and harms of classes of antibiotics approved for cUTI, starting with publications from 2008 onwards, and our review of predictors of resistance in uropathogens included references identified since 2000. These recommendations adhere to a standardized methodology for rating the certainty of evidence and strength of recommendation according to the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. Results The guidelines panel suggests initially selecting among preferred empiric antibiotic choices rather than alternative options, stratified for the patient's severity of illness and antimicrobial stewardship considerations. When choosing among these antibiotics for a specific patient, the guideline panel suggests a 4-step process to account for changing resistance patterns and individualized patient needs. The steps are: (1) assess the severity of illness (for initial prioritization of antibiotics), (2) consider patient-specific risk factors for resistant uropathogens (for optimization of coverage), (3) evaluate other patient-specific considerations (to reduce the risk of adverse events), and (4) for patients with sepsis, consult a relevant local antibiogram if available (to further improve the likelihood of giving appropriate empiric therapy). Lastly, the guideline panel suggests selecting definitive effective therapy with a targeted spectrum based on the result of the urine culture. Conclusions Many of the classes of antibiotics approved to treat cUTI demonstrate similar efficacy as other classes of antibiotics in randomized controlled trials. Bacterial resistance prevalence is always changing, and new antibiotics will be developed. In this context, the guidelines panel provides recommendations for choosing empiric antibiotic therapy for cUTI that will help clinicians decide among available antibiotic options at the point of care.

Abstract Introduction The EROS (Erectile Restoration Outcomes and Satisfaction) registry provides prospective questionnaire-based follow-up after IPP was founded in 2020 at the Mayo Clinic, Rochester. Objective We sought to assess general trends in the open-ended responses portion of the questionnaire. Methods Data were collected from 2020 to 2025, with a total of 568 responses. The survey included six open-ended questions pertaining to lifestyle change since IPP, reasons not to repeat the procedure, impediments to use, dissatisfaction, what patients wish they had known more about the procedure, and other recommendations. Evaluable data included 6-month responses from Rochester, Jacksonville, and Phoenix. Results Open-ended feedback was given by 66% of patients on what they wished they had known, 54% gave other recommendations, 38% gave lifestyle feedback, 7% elaborated upon reasons not using, 3% on reasons for dissatisfaction, and 2% on reasons they would not repeat IPP. There was an overall very positive response (“Significant Improvement”, n=74.3%) from those who underwent the IPP placement, with some patients reporting that it was far more convenient than other forms of treatment, and even increased spontaneity in their sexual lives, leading to improved relationships. Among the reported responses are increased confidence (n=39.4%), increased sexual activity (n=13.3%), and improved health and exercise levels (n=6.6%). When questioning patients on why they would not repeat the procedure and what their sources of dissatisfaction were, of those who responded to each question (n=12, n=16), the most report complaint was exaggeration of pre-existing curves (n=41.7%, n=25.0%), particularly due to Peyronie’s disease. When questioned about what prevents use, the main response was partner-related or due to personal problems (n=45.2%). The patients did not have many recommendations but hoped for a better way to deflate and inflate the device (n=20.4%) and reported adequate pre-operative education and use of the pump. The table below outlines the categories of responses and the percentage of each keyword reported per question type. Conclusions In addition to standard pre-operative IPP counseling, providers should provide additional focus on potential difficulty with device inflation/deflation, length loss (IPP not in glans), pain/ recovery expectations, potential of new or worsened curve (erect or flaccid), and potential change in sensation. IPP satisfaction is high, as only 2% of patients gave responses on why they would not repeat the IPP, with many men expressing an increased level of overall confidence. Disclosure No

Abstract Introduction Introduction: Peyronie’s disease (PD) is a fibrosing condition of the tunica albuginea characterized by a palpable plaque with varying impacts on the patient’s erection: curvature, shortening, indentations, hinging, and narrowing. Stepwise intralesional injection of collagenase clostridium histolyticum (CCH) is the only FDA approved medical treatment for PD. We retrospectively reviewed Xiaflex® treated patients for satisfaction with therapy or pursuit of subsequent surgery. Objective Objective: To assess global satisfaction with intralesional Xiaflex based on whether patients subsequently elected surgery. Methods Methods: This is a retrospective review of patients presenting with PD to a single center and managed by a single provider from 2020-2024 with six-month follow-up post-treatment. Patient presentations were recorded in an Institutional Review Board approved database. Data storage and analytics were conducted using REDCap. Results Results: The cohort for this study was 159 men treated with intralesional Xiaflex. 18 of the 159 were excluded from analysis due to ongoing treatment. 48.9% of patients (69/141) were satisfied with CCH outcomes and sought no further therapy. 51.1% of patients (72/141) were not satisfied with their outcomes. Of the patients not satisfied with treatment, 48/72 (66.7%) elected subsequent surgical interventions: 18 penile plications, 8 incision and grafting and 22 inflatable penile prostheses. 51.7% (73/141) of patients completed (8) CCH treatments. Among the 73 men who had a complete set of CCH injections, 24.6% (18/73) elected subsequent surgery. Among the patients who had fewer than 8 treatments 46.9% (30/64) elected surgery following Xiaflex. Conclusions Conclusion: If successful medical management of Peyronie’s disease is defined by men who decline subsequent surgical interventions, Xiaflex® was highly successful 75% (55/73). Patients who have Peyronie’s disease are highly motivated and will pursue surgical interventions following a trial of CCH. Disclosure No

Noninvasive electrophysiological source imaging (ESI) is a valuable tool for localizing and imaging brain activity, with significant potential to aid presurgical planning in focal drug-resistant epilepsy (fDRE) patients. Scalp electroencephalography (EEG) biomarkers, including interictal spikes, high-frequency oscillations (HFOs), and seizures, each offer unique capabilities in estimating the epileptogenic zone (EZ). However, there is a limited quantitative understanding of how these biomarkers differ in source-imaging precision, requiring distinct processing pipelines. Here, we developed a spatial–temporal–spectral imaging (STSI) framework for precision source imaging, and quantitatively evaluated various epilepsy biomarkers for source imaging in 2,081 individual events (spikes, HFOs, and seizures) from a cohort of 42 fDRE patients, comparing results to clinical ground truth such as surgical resection outcomes and intracranial EEG-defined seizure onset zones. The STSI enabled quantitative comparisons across key EEG epilepsy-related biomarkers, with averaged localization errors of 6.67 mm for seizures, 8.73 mm for HFOs overlapping with spikes (pHFO), 10.28 mm for HFO-riding spikes (pSpike), 19.59 mm for general spikes (aSpike), and 36.53 mm for general HFOs (aHFO), respectively, for seizure-free patients. These findings indicate that HFOs overlapping with spikes is the most spatially accurate interictal biomarker for mapping the EZ. The proposed STSI framework not only establishes a unified analysis approach for epileptic biomarkers to enhance presurgical planning in focal drug-resistant epilepsy, but could also generalize as a versatile tool for mapping event-related potentials, neural oscillations, and dynamic brain states, within a single framework to advance cognitive neuroscience research and clinical management of neurological and psychiatric disorders.

ABSTRACT Enzalutamide and abiraterone are hormonal treatments that improve survival in metastatic castration‐resistant prostate cancer. Identifying genetic variants associated with the clearance of these drugs may aid in improved dosing and outcomes. We performed genetic association studies of enzalutamide and abiraterone oral clearance in the Alliance A031201 clinical trial. Genome‐wide genotyping was performed with the primary analysis limited to European‐descent participants. Pharmacogene metabolic phenotypes were estimated using PyPGx and Stargazer. Associations of metabolic activity groups for CYP3A4 , CYP3A5 , CYP2C19 and SLCO1B1 with enzalutamide clearance ( N = 706) and CYP3A4 , SLCO2B1 and UGT1A4 with abiraterone clearance ( N = 323) were tested by linear regression. Targeted SNP associations were assessed for abiraterone clearance at loci proximal to major metabolizing genes. Full genome‐wide association studies were performed for both sets of clearance values. No significant associations were identified between metabolic phenotypes and enzalutamide or abiraterone oral clearance SNPs in the SULT2A1 5′ flanking region were significantly associated with lower abiraterone clearance, (rs296373, minor allele frequency = 0.15, β = −0.457, p = 3.2E‐06). Liver protein and liver and adrenal gland gene expression QTL databases indicated significantly lower SULT2A1 expression patterns for individuals carrying associated alleles, likely explaining the lower abiraterone oral clearance. CYP2C8*3 was associated with higher enzalutamide clearance ( p = 0.012), but this was not significant after correction for multiple testing. This study is the first to identify the genetic association of SULT2A1, known to be involved in the metabolism of steroids in the liver and adrenal glands, with abiraterone clearance. Genetic variation in SULT2A1 may be useful to inform personalized dosing of abiraterone. ClinicalTrials.gov Identifier: NCT01949337
