ABSTRACTBackgroundPeriodontal disease (PD) is a prevalent, preventable and treatable oral infection associated with substantial morbidity globally. There is little information from population‐representative cohort studies about the sociodemographic, educational and other early life factors that stratify PD risk.MethodsWe used data from the U.S. ‘High School and Beyond’ (HS&B:80) study, which has followed a nationally representative sample of 26,820 people from high school in 1980 through midlife in 2021. Data from the 1980s include information about education, early life circumstances, spatial location and demographic attributes. Data from 13,080 sample members who responded in 2021 include indicators of self‐reported PD diagnosis.ResultsPeople with higher degrees and course grades have a lower risk of midlife PD. Rural adolescents and those who attended private schools are also at lower risk. We find little evidence of heterogeneity in correlates of midlife PD by gender or race/ethnicity.ConclusionsThe quantity and characteristics of people's schooling and their location of residence are associated with midlife PD.
Accuracy of a Rapid-Response EEG's Automated Seizure-Burden Estimator
ABSTRACT There are limited and conflicting data on sex and urban‐rural disparities in outcomes of patients with pulmonary embolism (PE) in the reproductive age group. Our object was to assess sex disparities in the reproductive age group cohort. All adult non‐elective admissions in the reproductive age group (18−49 years) with a primary diagnosis of PE and with no missing sex/age data were identified using the National Inpatient Sample. Females and males were stratified into rural and urban location based on hospital information. Outcomes of interest included in‐hospital mortality, complication rates, variations in management, total hospitalization costs, and length of stay. During 01/01/2016 to 12/31/2020, 180,898 PE admissions aged 18−49 years were identified (rural—12,319 [6.8%]). Females comprised 54.8% and 55.1% of the rural and urban cohorts, respectively. Overall, compared to males, females in urban and rural regions had largely comparable rates of definitive PE interventions, except lower rates of catheter directed therapy (4.7 vs. 3.6%, p < 0.001) in females admitted to urban hospitals. Despite younger age, higher comorbidity, and lower utilization of PE interventions, females in both regions had similar unadjusted in‐hospital mortality (rural 1.1% vs. 1.0%; p = 0.93 and urban 1.8% vs. 1.7%; p = 0.78) and hospitalization costs compared to males. In conclusion, females of reproductive age group had comparable in‐hospital outcomes to males in both urban and rural areas. Females in urban areas had lower utilization of advanced PE interventions, potentially indicating selective management strategies in different settings.
(234) USING PERCUTANEOUS ULTRASOUND-GUIDED THROMBIN INJECTION AS A TREATMENT OF HIGH-FLOW PRIAPISM
Abstract Introduction Nonischemic priapism typically occurs secondary to penile trauma, resulting in increased blood flow into the penis without decreased outflow resulting in a clinically non-painful, partially rigid erection. Per the American Urologic Association guidelines, surgical treatment is discouraged, and following conservative management, first line treatment is arteriography with selective arterial embolization. This procedure is generally highly successful but it does carry a risk of erectile dysfunction as well as priapism recurrence. Objective Herein we present the first known case of ultrasound guided thrombin injection in an adult for nonischemic priapism treatment after persistent priapism and arterial blush following arterial embolization. Methods A 44-year-old male presented with an eight-month history of partial tumescence and erectile dysfunction after an episode of unwitnessed loss of consciousness resulting in the subsequent development of gross hematuria and dysuria. Physical examination revealed a semi-firm penis with suspected high-flow priapism. He initially presented to the emergency department, whereby a cystogram and cross sectional abdominal imaging were unrevealing. Initial outpatient cystoscopy revealed a urethral polyp which resolved on subsequent repeat testing. Following this an outpatient penile duplex doppler ultrasound was performed demonstrating a right pseudoaneurysm at the penile base measuring 13 mm in diameter with an arteriovenous fistulous communication to the corpus cavernosum. MRI demonstrates fibrotic changes within the right corpus cavernosum and tunica albuginea indicating prior traumatic penile injury. At the time the patient had approximately 25% tumescence at rest and was only able to obtain a slightly firmer erection, but was still able to achieve orgasm. After extensive conversation and given a trial of conservative management, the patient elected to proceed with angioembolization. An angiogram was completed which demonstrated a blush of contrast in the area of the bulbourethral artery. Despite successful deployment and coil embolization of the pseudoaneurysm, there was noted continued filling of the patent pseudoaneurysm from small branched collateral vessels. The patient tolerated the procedure well, and had reduction of his baseline penile tumescence and some erectile function recovery, requiring oral phosphodiesterase-5 inhibitors. There was concern for complete occlusion of the dorsal penile artery with repeat embolization, which may ultimately worsen erectile dysfunction. He remained incompletely satisfied with response to oral therapy. Results It was ultimately decided to pursue an ultrasound guided thrombin injection, which has been reported in a handful of cases as a primary intervention for priapism. During the procedure, 200 units of thrombin was injected into the pseudoaneurysm under ultrasound guidance resulting in immediate cessation of arterial flow. Post-procedure angiography demonstrated effective resolution. Conclusions High-flow priapism is a relatively uncommon condition, managed generally with embolization as first line treatment, with success rates reported at 89 to 100% and recurrence only occurring in 30% of patients. Recurrence is generally treated with repeat embolization which has been reported to cause erectile dysfunction in 15 to 22% of cases. Percutaneous ultrasound-guided thrombin injection has the potential to be an excellent second-line treatment option for pseudoaneurysm closure in correcting nonischemic priapism, albeit with limited data, but suspected high efficacy and potentially diminished rates of erectile dysfunction.

(222) MANAGEMENT OF A RETAINED NEEDLE - A COMPLICATION OF INTRACAVERNOSAL INJECTION THERAPY
Abstract Introduction Intracavernosal injections (ICI) is a well-established treatment for erectile dysfunction with common complications including priapism, penile ecchymosis and injection site pain. A rarer complication is breakage and retention of the needle inside the penis during self-injection, with only 16 cases reported in the literature from 1991 to 2023. Objective To report a case of needle breakage and retention as a complication of ICI and describe the optimal management of retained needle in the penis. Methods A 69-year-old male with a history of erectile dysfunction on TriMix presented to the Urology Department after half of his ICI needle broke off in the right side of his penis following self-injection. He denied having any pain or discomfort but reported that a small nodule had formed at the site. On physical examination, a nodule was palpated at the right base of his penis. He underwent pelvic X-ray and penile ultrasound, noting a 4-5 mm foreign body in the right base of the penis without gas in the soft tissue. As the retained needle was not significantly affecting him, he decided not to proceed with intervention and continued with ICI on the contralateral side. He began noticing burning pain at the site of injection, with development of a hard nodule that self-resolved each time. Due to worsening erectile function, he returned to clinic one year later to discuss inflatable penile prosthesis placement, where he inquired about removal of the retained needle. A small, nontender nodule was still noted at the right base of the penis. Results The patient underwent penile exploration in the operating room, revealing an obvious inflammatory fibrous nodule at the right base of the penis corresponding to the location of the needle on previous ultrasound. There was also a similar, smaller nodule contralaterally where the patient had continued ICI. Ultrasound guidance was used intraoperatively to identify the needle, then a spinal needle was used to triangulate with the needle fragment. The penis was sharply dissected along the spinal needle with iris scissors until the 4 mm needle fragment was identified and removed in its entirety. Dissection then began to excise the inflammatory nodule. However, despite attempts to completely mobilize Buck’s fascia and the nerves, the neurovascular bundles were quite adherent to the nodule from an inflammatory reaction and thus it was unable to be excised. A small possible corporotomy was then identified and repaired using 2-0 PDS. Injectable saline was then used to induce an erection and confirm no defects in the corpora. The patient recovered well post-operatively without any complications, and the nodules were noted to be much smaller at his one-month postoperative visit. Conclusions ICI needle breakage and entrapment in the penis is a rare complication. The diagnosis of needle retention includes imaging such as pelvic radiographs or penile ultrasound to locate the needle. While less invasive approaches can be attempted for removal, they may be less effective and cause further damage to surrounding tissue. Surgical exploration under ultrasound guidance is a safe and effective approach to needle removal. Disclosure No.
(154) MEN’S HEALTH AND THE LITIGIOUS PATIENT: A REVIEW OF MALPRACTICE CASES
Abstract Introduction Recent literature suggests growing rates of malpractice claims against Urologists, with the incidence of being sued seeming to be unrelated to one’s professional reputation. These cases provide insight into errors that may lead to litigation. Given national trends of rising malpractice cases, estimates that a Urologist can expect to be sued at least twice in their careers are likely underestimates. Malpractice cases can give insight into the common medical errors rising to the level of litigation. Given the elective nature of procedures within sexual medicine, understanding litigation related to these cases is crucial. Objective We aim to analyze malpractice suits related to men’s health and highlight clinical presentations and legal outcomes. Methods Per STROBE guidelines, we searched the publicly available Thomson Reuters Westlaw legal database for “jury verdicts and settlements” from January 1970 to August 2023 to identify medical malpractice cases in Urology. Patient demographics, clinical presentation, alleged error, and legal outcomes were abstracted during full case review by an independent screener. Cases related to men’s sexual health or fertility that named a urologist as the defendant were fully analyzed. Results A total of 553 Urology cases were extracted, with 23 men’s health related cases subsequently analyzed and summarized in Table 1. The most common conditions associated with litigation were erectile dysfunction (penile prosthesis) (39%), epidydimal pathology (13%), and varicocele (13%). The most common allegations were misdiagnosis (26%), surgical complication (22%), lack of informed consent (22%), and violation of standard of care (22%). Of the 23 cases, 57% ruled “no liability” in favor of the urologist, 39% ruled in favor of the plaintiff with a median award of $335,000 (IQR = 100,000-450,000), and one was settled for $316,338. Among cases ruled as negligent, performing the incorrect procedure, surgical complications, and violating the standard of care were prominent allegations. Florida (26%) and Pennsylvania (17%) had the most cases in this sample. Of note, there were no cases for penile plication, plaque excision, microsurgical cord denervation, vasectomy reversal, or sperm retrieval, and only one for vasectomy. Conclusions This study characterizes malpractice cases related to men’s sexual health naming urologists as defendants. Despite fear of litigation, this review of the Westlaw database revealed only 23 cases related to men’s health since 1970. Moreover, the majority of cases ruled in favor of the Urologist. Obtaining comprehensive informed consent, following national guidelines, and responding appropriately to surgical complications may minimize likelihood of litigation and maximize patient outcomes.

(149) 49,422 QUICK QUESTIONS: CHARACTERIZING THE PATIENT MESSAGE BURDEN OF A MEN’S HEALTH PRACTICE
Abstract Introduction The Electronic Medical Record (EMR) has had a positive impact on healthcare but it has also increased administrative burden on physicians. One reason for this is the patient portal, which grants patients 24/7 access to ask their physician questions. Objective To characterize the patient message volume of urologists with a Men’s Health Practice by quantifying message volume per case, identifying procedures linked to high message volume, and examining demographics affecting patient portal use. We then assess the clinical utility of patient portal messages by examining their effect on Emergency Department (ED) utilization. Methods We queried the EMR of a health system spanning the southeast, midwest, and southwest using internal procedure and surgical codes for all office and operating room based urologic procedures from March 2017-November 2023. We identified procedures related to Men’s Health focusing on andrology, sexual medicine, and male reconstructive procedures. Patients identifying as women, those with multiple procedures within 6 months, and patients without research authorization were excluded. To identify factors associated with active portal users and message volume, we performed univariate and multivariable logistic and linear regression models. Multivariable models consisted of all statistically significant factors on univariate analysis. In models utilizing the procedure variable to compare message volume, vasectomy was chosen as the reference procedure due to it having the highest case volume. To assess the impact of active portal use (defined as sending at least 1 message within 6 months of their procedure) on risk of subsequent ED visit, we performed univariate Kaplan–Meier analysis and univariate and multivariable Cox Proportional Hazard models treating portal use as a time-dependent covariate. Results We examined 16,299 procedures which generated 49,422 messages within 6 months of their procedure (Table 1). Demographic data can be seen in table 2. On average, 3.04 ± 6.88 messages were generated after each procedure. The highest message generating procedures were testosterone Injection/pellets (5.83 ± 9.57), Itind (5.73 ± 14.18), and Transurethral Incision of the Prostate (5.19 ± 13.19). The lowest message generating procedures were vasectomy (1.30 ± 3.10), spermatocelectomy (1.67 ± 3.80), and circumcision (2.32 ± 5.26). The types of cases that generated the highest overall message burden were male reconstructive procedures (4.53 ± 8.57) and BPH procedures (4.07 ± 8.40) and. Slightly less than half of our cohort were active on the portal (45%) within 6 months of their procedure (Table 1). The procedures that were the most likely to have active portal users were microtese (OR 5.03 95% CI 2.38,10.67), testosterone injection/pellets (OR 4.86 95% CI 3.13, 7.54), and Itind (OR 3.02 95% CI 2.16, 4.24). On time to event analysis we found that portal usage decreased the risk of presenting to the Emergency Department (ED) by 15% within 90 days of their procedure [HR (95% CI) 0.65 0.85 (0.77, 0.93)] (Fig. 1). Conclusions Urologists practicing Men’s Health receive a high number of messages per procedure that they perform, however the use of the patient portal reduces ED utilization. Resources should be allocated to help urologists manage their patient messages as it lowers healthcare costs. Disclosure No.
Cognitive and Procedural Competencies in the Cardiac Intensive Care Unit
Abstract BACKGROUND Recurrent anaplastic astrocytoma (AA), a grade 3 brain cancer, remains an unmet medical need. STELLAR was a phase III randomized, open-label trial of eflornithine (ornithine decarboxylase inhibitor) with lomustine versus lomustine alone, originally for patients with recurrent AA. However, as the WHO definition of AA evolved during trial conduct (e.g., excluding IDH wild-type disease), we determined results in both the original ITT population and by revised molecularly defined WHO 2021 diagnoses in pre-planned analyses. METHOD Key eligibility: age ≥ 18, AA (2016 WHO criteria), first recurrence ≥ 6 months after radiation and temozolomide, KPS ≥ 70, no imaging findings consistent with grade 4 glioblastoma. Stratification: IDH, age, resection extent, and geography. Patients were randomized to Arm A: eflornithine (2.8 g/m2 TID Q 2/3 weeks) with lomustine (90 mg/m2 Q 6 weeks) or Arm B: lomustine (110 mg/m2 Q 6 weeks). Primary endpoint was OS. The pre-specified hazard ratio (HR) goal was 0.667 based on projected median OS (mOS) increase to 18 months from 12 months. RESULTS 343 pts (172/171 Arms A/B) were randomized (105 sites, 8 countries). ITT analysis found no difference between arms (mOS 23.4 vs. 20.3 months, HR = 0.94). However, a pre-specified subset analysis in IDH mutant, 2021 WHO-defined grade 3 astrocytoma (n=194), showed significant improvement with eflornithine (mOS 34.9 vs. 23.5 months, HR = 0.64, log rank p = 0.016) and PFS (15.8 vs. 7.2 months, HR = 0.58, log rank p = 0.015). No difference was observed in the IDH wild-type subset. AEs were consistent with historic data. CONCLUSION There was no difference in OS between arms in the ITT analysis. However, medically meaningful and statistically significant OS and PFS benefits were observed with eflornithine in the pre-planned analysis of patients with molecularly defined 2021 WHO CNS grade 3 astrocytoma.
A Novel Machine Learning Model to Predict Revision ACL Reconstruction Failure in the MARS Cohort
Background: As machine learning becomes increasingly utilized in orthopaedic clinical research, the application of machine learning methodology to cohort data from the Multicenter ACL Revision Study (MARS) presents a valuable opportunity to translate data into patient-specific insights. Purpose: To apply novel machine learning methodology to MARS cohort data to determine a predictive model of revision anterior cruciate ligament reconstruction (rACLR) graft failure and features most predictive of failure. Study Design: Cohort study; Level of evidence, 3. Methods: The authors prospectively recruited patients undergoing rACLR from the MARS cohort and obtained preoperative radiographs, surgeon-reported intraoperative findings, and 2- and 6-year follow-up data on patient-reported outcomes, additional surgeries, and graft failure. Machine learning models including logistic regression (LR), XGBoost, gradient boosting (GB), random forest (RF), and a validated ensemble algorithm (AutoPrognosis) were built to predict graft failure by 6 years postoperatively. Validated performance metrics and feature importance measures were used to evaluate model performance. Results: The cohort included 960 patients who completed 6-year follow-up, with 5.7% (n = 55) experiencing graft failure. AutoPrognosis demonstrated the highest discriminative power (model area under the receiver operating characteristic curve: AutoPrognosis, 0.703; RF, 0.618; GB, 0.660; XGBoost, 0.680; LR, 0.592), with well-calibrated scores (model Brier score: AutoPrognosis, 0.053; RF, 0.054; GB, 0.057; XGBoost, 0.058; LR, 0.111). The most important features for AutoPrognosis model performance were prior compromised femoral and tibial tunnels (placement and size) and allograft graft type used in current rACLR. Conclusion: The present study demonstrated the ability of the novel AutoPrognosis machine learning model to best predict the risk of graft failure in patients undergoing rACLR at 6 years postoperatively with moderate predictive ability. Femoral and tibial tunnel size and position in prior ACLR and allograft use in current rACLR were all risk factors for rACLR failure in the context of the AutoPrognosis model. This study describes a unique model that can be externally validated with larger data sets and contribute toward the creation of a robust rACLR bedside risk calculator in future studies.
