Abstract Introduction Down-sized inflatable penile prosthesis (IPP) cylinders are used in challenging penile fibrosis scenarios, such as after priapism or prior implant infection. Their role in primary penile prosthesis surgery, however, is not well studied. Objective This study aims to identify factors associated with the use of down-sized cylinders in men undergoing primary IPP placement. Methods We conducted a multicenter, retrospective study on men undergoing primary IPP surgery, categorizing them into a down-sized cylinder group (AMS 700 CXR and Coloplast NB) and a standard cylinder group (AMS 700 CX, AMS 700 LGX, and Coloplast Titan). We collected demographic, intraoperative, and postoperative variables and performed a multivariable analysis. Results 4,389 men were included in the study with a mean age of 62.3±10.3 years. Overall, 1,485 (34%) men had diabetes, and 2,131 (49%) had hypertension. Down-sized cylinders were placed in 406 men (174 CXRs, 232 NBs), while standard cylinders were placed in 3,983. Multivariable analysis indicated that down-sized cylinders were more commonly used in men with diabetes (OR 2.6 [1.9, 3.7], p<0.001) and less frequently in men with hypertension (OR 0.5 [0.4, 0.7], p<0.001). A history of priapism did not significantly impact the use of down-sized cylinders (p≥0.152). Sequential dilation was performed more often with the use of down-sized cylinders (OR 4.0 [2.8, 5.7], p<0.001). Down-sized cylinders were associated with an increased rate of non-infectious complications (OR 1.9 [1.3, 2.9], p<0.001), however, there was no significant association with implant infection (OR 2.1 [0.9, 4.6], p=0.07). Non-infectious complications occurred in 44 (25%) men with down-sized cylinders. In the down-sized group, hematomas occurred in 10 (2.5%) men and wound-related complications occurred in 7 (1.7%) men (Table 1). Cylinder-related complications occurred in 7 (1.7%) men with down-sized cylinders. Device-related malfunctions were seen in 8 (2%) men. Conclusions This study demonstrates that down-sized cylinders are more frequently used in men with diabetes and surgeons should be prepared to place down-sized cylinders in these men. Prosthetic urologists are also more likely to use down-sized cylinders in men requiring sequential dilation likely due to fibrosis or more challenging dilations. Down-sized cylinders are associated with a low overall complication rate.

ABSTRACT Background and Objectives Occult intra‐abdominal metastases are identified in approximately 20% of patients with radiographically localized pancreatic ductal adenocarcinoma (PDAC) through staging laparoscopy, as peritoneal cytology is limited in sensitivity. Methylated DNA markers (MDMs) have demonstrated high diagnostic accuracy for PDAC in tumor tissue, blood, and pancreatic secretions. This study assesses the feasibility and diagnostic performance of MDMs in peritoneal lavage fluid collected during staging laparoscopy, comparing their performance to mutant KRAS (m KRAS ) detection. Methods DNA from peritoneal lavage fluid of PDAC patients was analyzed for m KRAS mutations (codons 12, 13, and 61) using droplet‐digital PCR and for 13 MDMs and a reference gene (B3GALT6) using quantitative methylation‐specific PCR. An MDM score was generated from the average signal of the 13 MDMs and evaluated for its ability to detect intra‐abdominal metastases via receiver operator characteristic (ROC) analysis. Results Among 48 patients, 15 (31%) had intra‐abdominal metastases. The MDM score showed 87% sensitivity and 90% specificity (AUC = 0.98), outperforming m KRAS , which showed 40% sensitivity and 85% specificity (AUC = 0.62; p < 0.0001). Conclusions MDMs in peritoneal lavage fluid may enable highly accurate molecular staging of PDAC and warrant validation in larger studies.

Background: Longitudinal assessments are increasingly common as a component of continuing certification programs offered by medical specialty boards. The goal of this study was to understand anesthesiologists’ utilization pattern, performance, and perception of the longitudinal assessment program administered by the American Board of Anesthesiology (Raleigh, North Carolina). Methods: The authors analyzed assessment usage and survey data from all anesthesiologists who participated in the Maintenance of Certification in Anesthesiology (MOCA) Minute from January 2018 to December 2019. Results: During the 24-month study period, 25,404 anesthesiologists completed all 120 questions assigned in at least 1 calendar year, collectively 5,801,160 responses to 1,646 unique questions. Participants were more likely to complete questions at the end of each quarter, with the highest frequency at the end of the year. Seventy-five percent of responses were first-time attempts, and 17% were first repeats. The median interval between original question presentation and first repeat was 314 days. The mean ± SD percent correct score was 68.3 ± 8.0% for first-time questions and 75.5 ± 12.6% for first repeats. The mean ± SD time to answer a first-time question was 26.8 ± 13.1 s, with shorter times for questions with correct than incorrect responses (25.0 ± 12.7 vs . 30.7 ± 13.3 s; time difference, −5.69 s; 95% CI, −5.71 to −5.66; P < 0.001). Of 5.11 million responses with ratings of relevance (88.2% of all responses analyzed), 4.86 million (95.2%) were felt to be somewhat or very relevant to practice. The percent correct scores were higher for responses with higher relevance and confidence ratings. For responses rated “not relevant,” “somewhat relevant,” and “very relevant,” the percent correct was 58.5%, 67.6%, and 77.0%, respectively; for responses rated as “unsure,” “somewhat confident,” and “very confident,” the percent correct was 53.6%, 67.9%, and 84.4%, respectively. Conclusions: MOCA Minute was generally used as designed. Evidence of learning was suggested by improved performance on repeat questions.

Abstract Aims To characterize global variation in cardiac rehabilitation (CR) staffing, indications, and prescribed dose by country income classification and compare findings with the International Council of Cardiovascular Prevention and Rehabilitation’s 2016 Global Audit. Methods and results Cross-sectional REDCap survey of Phase II/post-discharge CR programmes (May–September 2025). Outcomes were multidisciplinary team size/composition, accepted cardiac and non-cardiac indications, and centre-based CR dose. Comparisons were made across World Bank country income classifications and Audit decade (2016 vs. 2025). Of 7025 programmes identified globally, 1505 (median programme response rate = 62%/country) initiated a survey, from 90/113 (80%) countries with CR. CR was delivered by a multidisciplinary team of 7 (median; P25–P75 = 5–8; nurses, physiotherapists, cardiologists, and dietitians most common); teams were smaller in low-income countries (median = 4; P &lt; 0.001), and physician specialty varied. Non-low-income programmes consistently accepted (≥90%) patients with acute coronary syndrome, with programmes in low-income countries less often accepting related interventions (e.g. surgery: low-income 0% vs. high-income 97%; P &lt; 0.01), but non-cardiac indications were more frequently accepted (e.g. primary prevention, diabetes, and lung disease). Acceptance of heart failure increased compared with the previous Audit (70% vs. 87%; P &lt; 0.001). Centre-based programmes prescribed a median of 20 h (P25–P75 = 12–30), typically two sessions/week over 8 weeks. Globally, 65 (72%) countries prescribed a median ≥12 sessions/programme. Programmes in upper-middle-income countries prescribed more sessions (median = 24, P25–P75 = 12–36; P &lt; 0.001). Dose did not differ meaningfully between Audits (P = 0.07). Conclusion CR programmes globally are offered by small, but multidisciplinary teams. They accept guideline-indicated patients, with applicable variation by context. Insufficient dose in one-quarter of countries underscores investment need.

632 Background: Prospective data on the risk of breast cancer (BC) recurrence among young BC survivors who have a subsequent pregnancy are limited. We sought to evaluate the long-term impact of pregnancy and live birth on BC outcomes in the Young Women’s Breast Cancer Study (NCT01468246), a prospective multicenter study of women aged ≤40 years at BC diagnosis. Methods: Women with stage 0-III BC without prior hysterectomy were included. The primary endpoint was breast cancer-free interval (BCFI) between patients with and without a (a) pregnancy and (b) live birth after BC. Secondary endpoints were distant recurrence-free interval (DRFI) and overall survival (OS). A time-varying Cox proportional hazards model was performed by estrogen receptor (ER) status, controlling for age at diagnosis, tumor stage, HER2 status, tumor grade, parity at diagnosis, and germline pathogenic variant status. Results: Among 1,016 BC survivors at a median follow-up of 12 (range, 0.5-18.5) years, 198 reported ≥1 pregnancy and 165 reported ≥1 live birth post-diagnosis. Among survivors who reported a post-diagnosis pregnancy, median age at diagnosis was 32 (range, 17-40) years; most had stage I (35%) or II (40%) BC, with 72% hormone receptor (HR)-positive and 25% HER2+; 42% were nulligravid and 60% were nulliparous at diagnosis. Among BC survivors who did not become pregnant post-diagnosis, median age at diagnosis was 37 (range, 21-40) years; most had stage I (35%) or II (43%) BC, with 75% HR-positive and 28% HER2+; 25% were nulligravid and 29% were nulliparous at diagnosis. Among BC survivors with ER-positive tumors (n = 737), pregnancy after BC was not associated with a difference in BCFI (adjusted hazard ratio [HR] 0.60, 95% CI 0.31-1.16, P = 0.130), DRFI (HR 0.73, 95% CI 0.35-1.55, P = 0.416), or OS (HR 0.58, 95% CI 0.24-1.40, P = 0.227). Similarly, live birth after BC did not impact BCFI (HR 0.83, 95% CI 0.45-1.55, P = 0.560), DRFI (HR 1.04, 95% CI 0.52-2.06, P = 0.923), or OS (HR 0.77, 95% CI 0.34-1.76, P = 0.541). Outcomes among BC survivors with ER-negative tumors (n = 278) were also not affected by post-diagnosis pregnancy (BCFI [HR 1.48, 95% CI 0.70-3.14, P = 0.304], DRFI [HR 1.59, 95% CI 0.68-3.75, P = 0.287], OS [HR 0.99, 95% CI 0.39-2.49, P = 0.975]) or live birth (BCFI [HR 1.02, 95% CI 0.41-2.53, P = 0.974], DRFI [HR 0.80, 95% CI 0.24-2.69, P = 0.722], OS [HR 0.39, 95% CI 0.09-1.69, P = 0.208]). Conclusions: In this multicenter, prospective study with 12 years of median follow-up, pregnancy and live birth after BC did not impact BC events or overall survival, irrespective of ER status. These long-term data from a modern cohort provide reassurance for young BC patients interested in future fertility. Clinical trial information: NCT01468246 .

Abstract Background Whether outcomes of germline BRCA1/2 (gBRCA1/2)-associated breast cancer differ compared with sporadic tumors is controversial. We explored the impact of gBRCA1/2 pathogenic variant (PV) status beyond established prognostic features. Methods We conducted 2 retrospective, matched cohort studies comparing gBRCA1/2 PV carriers and noncarriers with HER2-negative, stage I-III breast cancer (Clinical Outcomes Quality Database [COQD] cohort: 185 carriers, 555 noncarriers; Young Women’s Breast Cancer Study [YWS] cohort: 113 carriers, 226 noncarriers). Matching factors were age, stage, hormone receptor status, and year of diagnosis. Clinicopathological features, treatments, and survival outcomes were compared between carriers and noncarriers. Results Most patients in COQD had stage I-II disease (87.2%), and more carriers than noncarriers had genetic testing before diagnosis (33% vs 5.6%, P &lt; .001). In YWS, 22.7% of patients had stage III tumors, and few were tested before diagnosis (14.8% of carriers vs 1.7% of noncarriers; P &lt; .001). Carriers in COQD received chemotherapy more often than noncarriers (81.1 vs 67.0%, P &lt; .001), including platinum (P = .010); the proportion was similar for carriers and noncarriers in YWS. After adjusting for chemotherapy, relapse-free survival was longer in carriers than noncarriers in COQD (adjusted hazard ratio = 0.48 [95% CI = 0.26 to 0.87], P = .016), and a favorable trend was observed for other survival outcomes in both cohorts. Triple-negative tumors appeared to drive the differences. Conclusions We observed a trend toward improved outcomes in gBRCA1/2 PV carriers compared with noncarriers. These findings suggest that carriers should not receive more aggressive treatment solely based on their germline mutation status. Prospective clinical trials in this population are warranted.

Abstract Background Breast cancer (BC) diagnosed during pregnancy or postpartum often presents with aggressive features, potentially influenced by hormonal, immunological, and tissue remodeling changes. Studies have suggested that postpartum BC may be associated with worse outcomes, though most evidence is retrospective and constrained by methodological limitations. This study evaluated associations between pregnancy history, recency of childbirth, and long-term outcomes in a prospective cohort of young patients with early-stage BC. Patients and Methods Patients aged ≤40 years with stage I–III BC enrolled in the Young Women’s Breast Cancer Study were categorized at diagnosis as nulligravid, nulliparous, pregnant, or parous (≤5 vs 5 to 10 years postpartum). Analyses were stratified by BC subtype (estrogen receptor-positive [ER+]/HER2−, HER2+, and triple-negative [TNBC]), with distant recurrence-free survival (DRFS) as the primary endpoint. Results Among 859 patients, 257 (29.9%) were nulligravid, 50 (5.8%) nulliparous, 37 (4.3%) pregnant, and 515 (60.0%) parous. Pregnant patients had proportionally more TNBC, nodal involvement, T3/T4, and grade 3 tumors. After 11.1 years median follow-up, pregnancy or postpartum status was not independently associated with DRFS in multivariable models adjusted for age, tumor characteristics, and treatment, with consistent findings across ER+/HER2−, HER2+, and TNBC subtypes. Sensitivity analyses, including further categorization of postpartum diagnoses (&lt;2 vs 2 to 5 years), yielded consistent results. Conclusions Pregnancy history and recency of childbirth were not independently associated with long-term DRFS. Despite more aggressive features at diagnosis, patients diagnosed during or after pregnancy had comparable outcomes after adjustment, suggesting no adverse prognostic impact.

ABSTRACT Distal urethral strictures involving the meatus and fossa navicularis present unique challenges for reconstructive urologists due to the short segment’s proximity to the glans and high stakes for cosmetic and functional outcomes. Traditional approaches such as ventral meatotomy, skin-flap urethroplasty, and 2-stage techniques are known to compromise cosmesis, increase the risk of urethrocutaneous fistula, and have high recurrence rates, particularly in patients with lichen sclerosis (LS). The evolution of one-sided dorsal onlay urethroplasty with buccal mucosa graft has increased the success rates of single-stage urethroplasties by emphasizing preservation of tissue vascularity, leading to robust graft support. Traditionally, literature described the one-sided dorsal onlay urethroplasty through a perineal incision. This review seeks to describe the refinement of this technique, adapting the one-sided dorsal onlay concept to distal strictures by accessing the urethra through a subcoronal, ventral, or penoscrotal incision. Ventral penile incisions may limit unnecessary dissection, preserve glans architecture, and allow for supine positioning, thereby mitigating risks associated with high dorsal lithotomy. All while retaining the advantages of a well-vascularized dorsal graft bed. Limited reports describe high rates of anatomic and functional success and low complication rates across etiologies, including LS, iatrogenic, and hypospadias repair. Failures tend to be focal and amenable to minor interventions.
