Abstract Introduction Penile implant (PI) surgery is a well-recognized strategy for erectile dysfunction (ED) with excellent functional/satisfaction outcomes. To date, little attention has been paid to the attitudes and satisfaction outcomes of female partners of such patients. Objective To qualitatively assess how female partners feel about PI surgery to inform the development of a female partner specific questionnaire. Methods Female partners of men who had undergone PI surgery (3-piece inflatable) underwent concept elicitation interviews. Prior to this, a panel of experts in female sexual health and PI surgery was convened to define potential domains of interest. Women were interviewed by one of two female sexual medicine clinicians to elicit concepts. As part of the spontaneous item generation phase, participants were asked about their attitudes, hopes and concerns prior to PI surgery, as well as changes in partner post-surgery. Participants were then asked whether they identified domains raised by the expert panel that were not mentioned during the spontaneous phase. Additional open-ended questions were asked about experiences before and after PI surgery. Interviews were transcribed verbatim for subsequent qualitative analysis by 2 trained members of the study team. Results 12 women have been interviewed. Mean partner age = 60 years, relationship duration = 20 years. Interviews were held <12 months post-PI for 17% of partners, 12-24 months for 25%, >24 months for 58%. Partner communication and involvement in decision to get the implant were uniquely raised as pre-surgical concerns, whereas PI attributes were uniquely mentioned as post-surgical concerns. How the PI has impacted the man’s self-esteem, whether impacts to self-esteem have affected the partner, and overall satisfaction with sex were most common concepts raised across pre- and post-surgery (See Table). Conclusions Using rigorous qualitative methodology, we have identified concepts that are unique to pre-surgery, post-surgery, and common across the surgical experience among partners of men who have undergone penile implant surgery. These data will facilitate development of a tool to assess female partner attitudes, beliefs and satisfaction prior to and after PI surgery. Disclosure No

Abstract Introduction Inflatable penile prosthesis (IPP) implantation is a common and effective surgical treatment for erectile dysfunction. However, the presence of comorbidities and the use of anti-thrombotic therapy (AT) can complicate surgical decision-making. Due to the correlation between erectile dysfunction and cardiovascular disease, the preoperative comorbidities of surgical patients are important to examine. Objective The goal of this study was to assess the outcomes of IPP implantation in men on active AT therapy compared to a non-AT therapy cohort. Methods A retrospective analysis from 2015 to 2023 was conducted using data from three high-volume implant centers. The study focused on men who underwent three-piece IPP placement. Demographics, comorbidities, secondary procedures, drain information, and complications were recorded. The three centers each have different techniques and approaches to the surgery. Center 1 utilizes a penoscrotal approach, never places a drain, and places the reservoir in an ectopic location. Center 2 utilizes an infra-pubic approach, places a drain which remains in place for 3 days, and utilizes various reservoir locations depending on patient profile. Lastly, center 3 utilizes a penoscrotal approach, places a drain with removal when output is less than 50 mL over 8 hours, and places the reservoir in an ectopic location. Outcomes were analyzed using multivariate and univariate analysis. Results A total of 210 patients on active AT therapy and 128 non-AT patients were included. The AT and non-AT groups showed significant differences in baseline comorbidities, with the AT group exhibiting higher rates of cardiovascular disease, hypertension, and thrombosis (p<0.05). Among patients on anti-thrombotic therapy, 27.6% required revision surgeries and had increased rates of ectopic reservoir placement compared to the non-AT group (p<0.001). Despite these differences, there were no statistically significant variations in overall complication rates between the two groups. Drain output was notably higher in the AT cohort on postoperative days 1 (mean 110.5 cc vs 60 cc, p<0.001) and 2 (mean 78 cc vs 20 cc, p<0.001); however, hematoma rates remained comparable between both groups (p=0.667). Importantly, neither the type of anti-thrombotic therapy nor the surgical approach used appeared to influence postoperative outcomes. Eleven patients (5.2%) experienced complications in the AT arm and 5 patients (3.9%) experienced complications in the non-AT arm (p=0.793). Conclusions IPP implantation is feasible and safe in men on active anti-thrombotic therapy when performed in high-volume centers with appropriate perioperative management. Further studies with larger cohorts and longer follow-up are needed to refine protocols and determine long-term outcomes for these high-risk patients. Disclosure No

Abstract Introduction 0.05% Chlorhexidine Gluconate (CHG) has gained popularity as an irrigant and dip for inflatable penile prosthesis (IPP) surgery. Prior in vitro data is conflicting on the impact of CHG use with hydrophilic coated devices. Objective We sought to identify possible associations between CHG use and hydrophilic IPP infection rate. Methods We conducted a retrospective cohort study of 2,933 patients undergoing IPP implantation across 14 referral centers. Data collection spanned from January 1, 2017 to March 1, 2024. Each surgeon contributed patients who underwent IPP implantation with CHG used as an irrigant and/or dip as well as an equal number of consecutive control patients without CHG use. The primary outcome was IPP explant for postoperative infection. Univariable analysis was used to compare patient demographics, and logistic regression analysis was performed to assess factors associated with infection. Results Hydrophilic devices were implanted in 2,150 patients. Median follow-up for non-CHG patients was 13 months (IQR 18) and four months (IQR 9) for CHG patients. The incidence of infection with intraoperative CHG use was significantly higher compared to those without CHG use (4.6%, 46/1,001 vs. 2.1%, 24/1,148, p<0.001). On multivariable logistic regression analysis, intraoperative CHG use was associated with infection (OR 2.07, 95% CI 1.24-3.47, p=0.01). Additional variables associated with infection included immunosuppression, prior IPP infection, prior priapism, and revision surgery (p<0.01, Table). On subgroup analyses, the increased infection risk of CHG was most clear when CHG was used as both irrigation and dip (OR 2.03, 95% CI 1.19-3.46, p=0.01) and when CHG was used during revision surgery (OR 3.36, 95% CI 1.15-9.82, p=0.03). Conclusions In a large multi-institutional cohort, intraoperative CHG use was associated with an elevated incidence of hydrophilic IPP infection. Providers may take these findings into consideration when performing IPP surgery with hydrophilic devices, especially during revision surgery.

Abstract Introduction While previous research has explored overall satisfaction following IPP surgery, the specific relationship between final implant length and perceived satisfaction in both patients and their partners remains underexplored. Objective We aim to evaluate the association between IPP cylinder length and postoperative satisfaction in both patients and their sexual partners, and to determine whether perceived adequacy of length restoration correlates with overall sexual and psychosocial outcomes. Methods We initiated a registry of patients undergoing surgery for placement of a PP. After consent, perioperative study assessments and follow-ups were conducted. After surgery, patients were directed to fulfill a survey at 6 months and 12 months. Patients who fulfilled both items were included in the analysis. Results A total of 237 patients had a PP placement and completed the first survey and 158 the 12-month survey. The median IPP length was 22 cm (20-23). At 6 months, .189 patients (79.7%) reported moderate to high satisfaction, and this positive response was sustained at 12-months (n=132; 83.5%). At 6 months, 178 patients (75.1%) reported moderate to high partner’ satisfaction, and this positive response was sustained at 12-months (n=129; 81.6%). A regression analysis at 6 months showed a correlation of r=0.148 (p=0.029) and r=0.027 (p=0.743) at 12 months, implying that while significant statistically, it is not strongly related, and other factors are likely contributing to the response. Partner satisfaction showed a correlation of r=0.184 (p=0.008) at 6 months and r=0.032 (p=0.702) at 12 months, again showing no causal relationship between length of the IPP device with perceived satisfaction. A secondary analysis was performed in patients who had prostatectomy and were using vacuum devices before IPP placement (n=51). Of these, 12 (5.1%) reported decreased penile size during pre-op counseling. The median IPP length was 22 cm (19.5-23) and 21 cm (19.6-22) among patients who reported a decrease in size before IPP placement (p=0.574). There was no correlation between this statement and IPP length (p=0.572), nor satisfaction levels in both patients r=0.180 (p=0.221) and partners r=0.015 (p=0.921) at 6 months or 12 months r=0.060 (p=0.701) & r=0.078 (p=0.636). Conclusions IPP length showed a significant correlation but a weak association with patient and partner satisfaction. Our findings underscore the need for a multimodal approach when looking for patient and partner satisfaction and not only to perceived cosmesis. Comprehensive preoperative counseling should address these multidimensional aspects to better align expectations and outcomes.

Abstract Introduction The opioid epidemic has encouraged increased efforts to minimize postoperative opioid use, particularly in urologic procedures. While short-acting local anesthetics are often used in inflatable penile prosthesis (IPP) placement, their effects diminish quickly, potentially leading to higher opioid requirements. Liposomal bupivacaine (LB), a long-acting local anesthetic, may reduce opioid requirements, but its cost and limited prospective data in IPP patients warrant further investigation. Objective To compare the efficacy of long-acting liposomal bupivacaine with short-acting ropivacaine in reducing postoperative pain and opioid consumption following inflatable penile prosthesis (IPP) placement. Methods This randomized controlled trial enrolled adult males undergoing primary IPP placement via a penoscrotal approach. Participants were randomized to receive either LB (20 mL Exparel + 20 mL bupivacaine 0.25%) or ropivacaine (40 mL of 0.5%) as part of a standardized multimodal analgesia protocol. All patients received acetaminophen, gabapentin, and meloxicam perioperatively, with oxycodone prescribed as needed postoperatively (figure 1). The primary outcome was postoperative opioid consumption measured in oral morphine equivalents (OME). Secondary outcomes included pain and anxiety scores assessed on postoperative days (POD) 3, 7, and 14 using visual analog scales. Results Only 13 patients completed the study due to difficulties in recruitment (9 in the long-acting group, 4 in the short-acting group). The long-acting group demonstrated consistently lower opioid consumption at all follow-up points. On POD 3, the median cumulative OME was 7.5 vs. 41.25 in the short-acting group. By POD 14, cumulative OME was 15.0 vs. 93.75. (Figure 2) Pain scores followed a similar pattern, with the long-acting group reporting lower median scores on POD 3 (4 vs. 6) and POD 7 (4 vs. 6). Anxiety scores were also lower in the long-acting group throughout the follow-up. Use of non-opioid analgesics was similar across both groups. Conclusions Despite a limited sample size, this trial showed consistent trends favoring LB over ropivacaine for reducing opioid use and pain following IPP placement. These findings suggest potential clinical benefit but require validation in larger, multicenter studies. The trial also illustrates the difficulty of conducting randomized studies when institutional practices strongly favor one approach.

Abstract Rheumatoid arthritis (RA) is a chronic disease involving inflammation of the joints. While the etiology of RA remains unknown, evidence exists for a significant contribution of the major histocompatibility complex (MHC). Environmental factors are also indicated as playing an etiological role. Since it is impossible to define the mechanisms contributing to disease onset and progression in humans, mouse models have been used widely. While many animal models have been generated by immunization with self‐proteins to induce arthritis, type II collagen (CII)‐induced arthritis is one of the most commonly used models utilized to understand the immunopathology of RA. CII constitutes 80% to 90% of total collagen content of hyaline cartilage found in joints and is a genetically conserved sequestered protein. Immunization with heterologous CII with an adjuvant in mice leads to cellular and humoral responses to heterologous and autoreactive CII‐specific responses and collagen‐induced arthritis (CIA). Mice immunized with CII develop inflammatory arthritis that shares many similarities in clinical, serological, and radiological features with RA in humans. However, selecting an antigen for inducing arthritis and the mouse strain are important, as not all strains are susceptible to CIA. A critical difference between RA and CIA is that in mice that lack the expression of human MHC II, the development of CIA is linked to the H2A locus, which is the homologue of HLA‐DQ, while most human studies have linked RA susceptibility with HLA‐DR alleles. Mice expressing HLA‐DQ and HLA‐DR molecules have been used to understand the role of MHC genes in susceptibility to RA. The protocols for inducing CIA in the HLA expressing transgenic mice described in this article can be used to understand how the different HLA molecules confer susceptibility to RA. © 2025 Wiley Periodicals LLC.

Objectives: In the United States, training for physicians who manage critically ill adult patients (intensivists) evolved through parallel subspecialty critical care medicine (CCM) pathways with significant commonality. The Society of Critical Care Medicine Adult Critical Care Physician Core Knowledge and Skills Task Force aimed to delineate the common core knowledge and skills required of all intensivists. Design: A master list of content areas and procedural skills was compiled from all CCM subspecialty program requirements and blueprints of the certification examinations. Using a modified Delphi approach, participants were asked to categorize the knowledge items as “advanced knowledge is essential,” “general, but not advanced, knowledge is essential,” or “knowledge is not essential.” Procedures were categorized as “intensivist performs routinely,” “intensivist only performs in an emergency,” or “intensivist knows” about the procedure. Setting: Representatives from CCM stakeholder organizations, including accreditation and certification organizations, critical care societies, and program directors’ societies, were invited to participate. SUBJECTS: Members of the Adult Critical Care Physician Core Knowledge and Skills Task Force of the Society of Critical Care Medicine. Interventions: For the first two rounds of the modified Delphi process, Research Electronic Data Capture was used. For the third and fourth rounds, the process was completed through online meetings with Zoom (Zoom Video Corporations, San Jose, CA) utilizing Zoom’s polling feature. Measurements and Main Results: A total of 541 items were determined to be essential, with 145 requiring advanced knowledge and 323 requiring general knowledge. For 73 items, consensus regarding advanced vs. general could not be achieved, but they remained essential. Only eight items were felt to be nonessential. Of the 16 procedures, most were categorized as “intensivist performs.” Conclusions: The large number of items included in the list of essential knowledge and skills demonstrates the complexity of modern CCM. Utilization of a common framework across the subspecialties of CCM could lead to greater harmonization among the fellowship program requirements and certification examinations.

Delirium is a serious neuropsychiatric condition marked by acute confusion and cognitive decline, commonly affecting postoperative and critically ill patients. It is especially prevalent in older adults and those requiring intensive care, including patients undergoing major surgery or receiving mechanical ventilation. For anesthesiologists, delirium is a critical and often underrecognized postoperative complication with complex perioperative contributors. Intensive care unit patients with delirium face increased mortality, cognitive impairment, and persistent symptoms beyond discharge. Despite its clinical significance, the pathophysiology of delirium remains poorly understood, with no standardized classification or targeted therapy. In light of emerging evidence connecting blood–brain barrier (BBB) permeability to the onset of delirium, we found that BBB dysfunction may represent a key mechanism underlying its pathophysiology. Through a thorough examination of predisposing and precipitating factors that impair both BBB integrity and cognitive function, we identified many points of connection between BBB dysfunction and delirium specifically. We include here a summary of our diagnostic approach with the aim of improving therapeutic strategies based on preserving BBB function to prevent or mitigate delirium.

This practice guideline addresses perioperative pain management using local and regional anesthesia for cardiothoracic, mastectomy, and abdominal surgery in adults and children. For adults, the American Society of Anesthesiologists (Schaumburg, Illinois) Task Force on Perioperative Pain Management strongly recommends fascial plane blocks to reduce pain and/or opioid requirements in the first 24 h postoperatively for open cardiothoracic, abdominal, retroperitoneal, and pelvic surgeries and mastectomy. Fascial plane blocks are also recommended in adults to reduce pain and/or opioid requirements after minimally invasive abdominal procedures. The Task Force conditionally recommends use of fascial plane blocks for minimally invasive cardiothoracic surgeries and open hernia repair to reduce pain in the first 24 h postoperatively. For children, the Task Force strongly recommends use of fascial plane blocks to reduce pain/and or opioid use after open cardiac or thoracic surgeries. Fascial plane blocks are conditionally recommended to reduce pain the first 24 h in children undergoing open hernia repair. Overall, data analysis for this practice guideline was limited by low methodologic quality, inconsistencies in outcome measurements, and small sample sizes from individual centers. Future research in regional anesthesia and analgesia needs to address these pervasive limitations.
