From discovery to innovation in animal health: Maturing emerging technologies for industrial development.

The Discovery to Innovation in Animal Health Conference (DIAH) was organised to bridge the gap between early developers, including academia, regulators, research organizations, and spin-offs/start-ups on one side, and medium-to large-sized companies on the other. The DIAH Conference confronted and aligned vision from academia, industry and regulators, emphasizing the need for early collaboration, careful IP management, and strategic planning for successful product development and partnerships. Recent breakthroughs in vaccinology have not only accelerated the vaccine production process but have also improved antigen quality significantly. These novel technologies are likely to transform vaccine development and play a crucial role in addressing both immediate health challenges (such as cancer vaccines) and ensuring preparedness for future pandemics. The potential and pitfalls of leveraging AI to drive forward R&I activities in the field of animal health were also discussed. Researchers and entrepreneurs looking for collaboration or investment presented a series of new technologies and start-ups, respectively. A market analysis showed that the animal health industry, while highly consolidated, also shows great diversity, ranging from big pharma to companies offering diagnostics, nutritional health services, wearables, feed additives, animal feed and genetic analyses. An analysis of the investment landscape, although subject to external factors, showed that the chances for success are high when good science, a well established regulatory pathways, with a clearly defined market need can be combined with experienced management and a strong investor consortium.

Being Social May Be Purposeful in Older Adulthood: A Measurement Burst Design.

OBJECTIVE: Sense of purpose predicts a wide array of positive health, cognitive, and well-being outcomes during older adulthood. However, work is limited regarding how social relations correspond to purposefulness in daily life. The current study explored daily social interactions as a route to daily purposefulness in older adults, using a measurement burst design. METHODS: Older adults completed surveys for three 5-day bursts each spread 6 months apart (Mage = 70.75, SD = 7.23; N = 104). RESULTS: Multilevel models demonstrated that on days when individuals reported more positive social interactions, they reported feeling more purposeful (est. = 0.39, 95% CI [0.28, 0.51]) when accounting for health, employment, and relationship status. Employment status moderated this association, as daily social interactions were more strongly associated with daily purpose for unemployed/retired individuals (est. = -0.23, 95% CI [-0.38, -0.08]). CONCLUSION: Positive social interactions thus may help older adults maintain purposefulness, particularly after retirement.

Influence of Clinical Expertise Between Clinician-Instructors Versus Student-Instructors on the Effectiveness of Ultrasound Courses.

PURPOSE: To investigate how the extent of an ultrasound instructor's clinical expertise influences the level of hands-on ultrasound competency achieved by clinicians after three-day ultrasound courses in abdominal and emergency ultrasound. The second goal was to determine how physicians in residency rate the sonographic and didactic skills of student instructors compared to medical staff instructors. METHOD: A total of N = 100 residents participating in a 3-day ultrasound workshop were randomly trained either by 15 student instructors or by clinical staff physicians, both with > 2 years of teaching experience. Both instructor groups had previously completed 120 hours of didactic instructor training. Ultrasound competencies were assessed by a standardized objective structured clinical examination (OSCE) of healthy individuals. The sonographic and didactic skills of both instructor groups were rated by questionnaires with six-step Likert items (1 = excellent, 6 = poor). RESULTS: The cohort, trained by student instructors, achieved the same scoring level as the second cohort, trained by physician instructors (mean score 76.4, versus 73.7 of max. 100 points, p = 0.28) in the final OSCE. The sonographic qualification was rated for student educators as 1.44 (mean) [1.1-1.62], versus residents 1.46 [1.26-1.61], versus attendings 1.29 [1.05-1.61]. Didactic skill levels were rated without significant differences with means of 1.53, 1.57 and 1.53, respectively. DISCUSSION & CONCLUSION: The didactic competence of student instructors does not differ statistically from the competency levels of experienced physicians. In terms of the acquired ultrasound skills of trainees, our data indicate that student instructors can be as efficient as staff instructors. Therefore, student instructors can be employed as resource-saving ultrasound educators without decreasing the skills level achieved by course participants, provided that they previously underwent a comprehensive didactic and sonographic training program.

Revisiting the penoscrotal approach to artificial urinary sphincter surgery: how does it compare to a perineal incision for initial implantation?

PURPOSE: Artificial urinary sphincters (AUS) remain the gold standard to treat male stress urinary incontinence. AUS implantation can be performed through a penoscrotal or perineal incision depending on surgeon preference. METHODS: The present study compares initial AUS implantation through two surgical approaches focusing on outcomes of continence and revision. All AUS implanted at an academic medical center between 2000 and 2018 were retrospectively reviewed. RESULTS: A total of 225 AUS implantations were identified, of which, 114 patients who underwent virgin AUS placement were included in the study with a mean follow-up of 28.5 months. A total of 68 patients (59.6%) had AUS placement through penoscrotal incision; while, 46 (40.4%) had a perineal incision. While operative time was significantly shorter for penoscrotal placement (98.6 min vs. 136.3 min, p = 0.001), there were no significant differences in continence rates between either surgical approach with 76.5% socially continent defined as using zero to less than 1 pad per day (safety pad). The overall rate of device erosion or infection was not significantly different between groups. However, the rate of revision or replacement was significantly higher in the perineal group (26.1% v. 8.8%; p = 0.01). On multivariate analysis, the penoscrotal incision predicted a lower rate of device revision (p = 0.01). CONCLUSIONS: The penoscrotal approach of AUS placement is associated with shorter operative time. While we observed a lower revision rate compared to the perineal approach, there were equivalent continence outcomes.

Antibiotic prophylaxis after urethroplasty may offer no benefit.

PURPOSE: Patients often receive antibiotic prophylaxis after urethroplasty to minimize the risk of urinary tract infection (UTI). The aim of this study was to determine the frequency of UTIs after urethroplasty and its impact on urethral and incisional healing. METHODS: Patients undergoing urethroplasty by a single surgeon from 2000 to 2012 were retrospectively reviewed. All patients received preoperative antibiotic prophylaxis and postoperative prophylaxis for 30 days or until catheter removal. We reviewed urine cultures obtained within 30 days after urethroplasty in symptomatic patients, and rates of stricture recurrence and wound complications. A positive culture was defined as > 1000 cfu/mL of an organism. RESULTS: 398 patients were included with a mean age of 43.5 years at time of surgery. We identified 102 positive urine cultures (25.6%) within 30 days of urethroplasty. 78 stricture recurrences (19.6%) occurred at an average of 3 years after surgery and 18 (4.5%) experienced a wound complication, with a 52 month mean follow-up. There were no significant differences in stricture recurrence (p = 0.36) or wound complications (p = 0.42) between patients who had a positive and negative urine culture. On multivariate analysis, positive urine cultures (HR 1.0, 95% CI 0.6-1.8, p = 0.88) were not associated with stricture recurrence, while lichen sclerosis (HR 3.2, 95% CI 1.1-9.2, p = 0.03) and previous urethroplasty (HR 2.3, 95% CI 1.1-4.6, p = 0.03) were. CONCLUSION: Bacterial colonization and UTIs despite antimicrobial prophylaxis are common in urethroplasty patients. This, however, does not appear to impair urethral healing or influence wound healing, suggesting that postoperative prophylaxis may in fact offer no benefit.

Long-Term Knowledge Retention after Peer-Assisted Abdominal Ultrasound Teaching: Is PAL a Successful Model for Achieving Knowledge Retention?

BACKGROUND: Diagnostic ultrasound has a crucial importance in clinical settings, especially in intensive care medicine where bedside ultrasound has become indispensable. Medical students as well as residents therefore have a strong interest in learning this useful skill. Since staff resources are limited, more and more universities are using student tutors in a peer-assisted learning concept (PAL) to teach medical students early in their training. To date, there is very sparse data about knowledge retention after peer-assisted teaching. The aim of this study was to evaluate whether PAL is a suitable method for teaching complex skills like abdominal ultrasound and to evaluate whether students do achieve adequate long-term knowledge retention after peer-assisted teaching. METHOD: A total of 40 volunteer 3rd to 5th year students were randomly assigned to a basic abdominal ultrasound course in small training groups of 5 persons each. Participants were evaluated using a pre-post-test design by a validated objective structured clinical examination (OSCE) before and immediately after the course. To measure the retention of knowledge, 15 former participants were randomly selected to repeat the OSCE assessment after one year. RESULTS: All groups showed a significant improvement in practical skills and knowledge gain after the training with mean values of 13.1 for pre-test compared to 83.5 (maximum 100 points) for post-test (p < 0.001). The overall score achieved after one year was 78.7 and did not significantly differ from the post-test result. CONCLUSION: PAL is effective for teaching abdominal ultrasound. Students were able to accomplish a satisfactory level of ultrasound skills. We further demonstrated that PAL can assure long-term knowledge retention.

Diagnostic value of biopsy sampling in predicting histology in patients with diffuse malignant pleural mesothelioma.

BACKGROUND: The classification of diffuse malignant mesothelioma into epithelioid, biphasic, and sarcomatoid types is based on histologic patterns. The diagnosis is made on biopsies, and because of intratumoral heterogeneity, they may not be representative of the entire tumor. The number and volume of biopsies needed to reach diagnostic accuracy in diffuse malignant mesothelioma and their prognostic value remain unclear. METHODS: This study examined 759 consecutive patients with pleural diffuse malignant mesothelioma treated by pleurectomy/decortication or extrapleural pneumonectomy for the presence of epithelioid and/or sarcomatoid histology and classified both the presurgery biopsies (core-needle or thoracoscopic) and surgical resection specimens. The number and volume of biopsies were correlated with pre- and postsurgery histologies and overall survival. RESULTS: Diffuse malignant mesothelioma was classified as epithelioid (76%), biphasic (18%), sarcomatoid (5%), or indeterminate (1%) in biopsies and as epithelioid (64%), biphasic (32%), and sarcomatoid (4%) in surgical resection specimens (overall concordance, 80.6%). The positive likelihood ratios were 2.4, 13.6, and 90.1 for biopsies with epithelioid, biphasic, and sarcomatoid histologies, respectively. Concordant histologies between biopsies and resections were associated with a higher number of biopsies (median tissue blocks for concordant histologies vs discordant histologies, 3 vs 2; P < .002) but were less associated with a higher volume (median, 1.2 vs 1.1 cm3 ; P = .06). In a multivariate analysis, overall survival was independently predicted by histology in the resection specimen (P < .0001) but not in the biopsy (P = .09). CONCLUSIONS: In contrast to epithelioid histology, sarcomatoid histology in biopsies is highly accurate. Despite intratumoral heterogeneity, the accuracy of histologic classification increases with the number of tissue blocks examined, emphasizing the diagnostic value of extensive sampling by presurgery biopsies.

Focusing large spectral bandwidths through scattering media.

Wavefront shaping is a powerful method to refocus light through a scattering medium. Its application to large spectral bandwidths or multiple wavelengths refocusing for nonlinear bio-imaging in-depth is however limited by spectral decorrelations. In this work, we demonstrate ways to access a large spectral memory of a refocus in thin scattering media and thick forward-scattering biological tissues. First, we show that the accessible spectral bandwidth through a scattering medium involves an axial spatio-spectral coupling, which can be minimized when working in a confocal geometry. Second, we show that this bandwidth can be further enlarged when working in a broadband excitation regime. These results open important prospects for multispectral nonlinear imaging through scattering media.

Manipulating the transmission matrix of scattering media for nonlinear imaging beyond the memory effect.

The measurement of the transmission matrix (TM) of a scattering medium is of great interest for imaging. It can be acquired directly by interferometry using an internal reference wavefront. Unfortunately, internal reference fields are scattered by the medium, which results in a speckle that makes the TM measurement heterogeneous across the output field of view. We demonstrate how to correct for this effect using the intrinsic properties of the TM. For thin scattering media, we exploit the memory effect of the medium and the reference speckle to create a corrected TM. For highly scattering media where the memory effect is negligible, we use complementary reference speckles to compose a new TM, not compromised by the speckled reference anymore. Using this correction, we demonstrate large field of view second harmonic generation imaging through thick biological media.

Prostate cancer risk regions at 8q24 and 17q24 are differentially associated with somatic TMPRSS2:ERG fusion status.

Molecular and epidemiological differences have been described between TMPRSS2:ERG fusion-positive and fusion-negative prostate cancer (PrCa). Assuming two molecularly distinct subtypes, we have examined 27 common PrCa risk variants, previously identified in genome-wide association studies, for subtype specific associations in a total of 1221 TMPRSS2:ERG phenotyped PrCa cases. In meta-analyses of a discovery set of 552 cases with TMPRSS2:ERG data and 7650 unaffected men from five centers we have found support for the hypothesis that several common risk variants are associated with one particular subtype rather than with PrCa in general. Risk variants were analyzed in case-case comparisons (296 TMPRSS2:ERG fusion-positive versus 256 fusion-negative cases) and an independent set of 669 cases with TMPRSS2:ERG data was established to replicate the top five candidates. Significant differences (P < 0.00185) between the two subtypes were observed for rs16901979 (8q24) and rs1859962 (17q24), which were enriched in TMPRSS2:ERG fusion-negative (OR = 0.53, P = 0.0007) and TMPRSS2:ERG fusion-positive PrCa (OR = 1.30, P = 0.0016), respectively. Expression quantitative trait locus analysis was performed to investigate mechanistic links between risk variants, fusion status and target gene mRNA levels. For rs1859962 at 17q24, genotype dependent expression was observed for the candidate target gene SOX9 in TMPRSS2:ERG fusion-positive PrCa, which was not evident in TMPRSS2:ERG negative tumors. The present study established evidence for the first two common PrCa risk variants differentially associated with TMPRSS2:ERG fusion status. TMPRSS2:ERG phenotyping of larger studies is required to determine comprehensive sets of variants with subtype-specific roles in PrCa.

Surgical Approaches and Long-Term Outcomes in Adults with Complex Reoperative Hypospadias Repair.

PURPOSE: Patients with failed hypospadias repair are a challenging population for pediatric and reconstructive urologists. We describe our long-term outcomes and factors associated with complications of repeat hypospadias repair. MATERIALS AND METHODS: We retrospectively reviewed the records of 32 adult patients with a history of hypospadias repair who required subsequent urethroplasty between 2002 and 2012. Data on the presenting complaint, past medical and surgical history, demographic data, surgical approach, intraoperative findings and complications were collected and analyzed. RESULTS: Median patient age at urethroplasty was 32 years. Stricture of the penile urethra was the most common presentation. Urethroplasty was done in 30 patients as stricture treatment, 1 underwent perineal urethrostomy and 1 underwent diverticulectomy. Two-stage repair was performed in 90% of the men who underwent urethroplasty. The initial success rate was 83% in patients who underwent 1 or 2-stage urethroplasty. At a median followup of 9.5 years complications included 4 recurrent strictures and 1 fistula. Patient age, previous interventions, stricture length, hair present at the time of repair, the need to excise the urethral plate and the number of stages were not associated with complications or recurrence. If a graft was required, skin grafts were significantly associated with recurrence compared to buccal mucosa grafts. CONCLUSIONS: Excellent outcomes can be achieved using a 2-stage approach with replacement or augmentation of the urethral plate in adults with failed hypospadias repair. In our experience buccal mucosa appears to be associated with fewer complications and less stricture recurrence than skin grafts.

Wide field fluorescence epi-microscopy behind a scattering medium enabled by speckle correlations.

Fluorescence microscopy is widely used in biological imaging, however scattering from tissues strongly limits its applicability to a shallow depth. In this work we adapt a methodology inspired from stellar speckle interferometry, and exploit the optical memory effect to enable fluorescence microscopy through a turbid layer. We demonstrate efficient reconstruction of micrometer-size fluorescent objects behind a scattering medium in epi-microscopy, and study the specificities of this imaging modality (magnification, field of view, resolution) as compared to traditional microscopy. Using a modified phase retrieval algorithm to reconstruct fluorescent objects from speckle images, we demonstrate robust reconstructions even in relatively low signal to noise conditions. This modality is particularly appropriate for imaging in biological media, which are known to exhibit relatively large optical memory ranges compatible with tens of micrometers size field of views, and large spectral bandwidths compatible with emission fluorescence spectra of tens of nanometers widths.

Synchronous Ipsilateral High Submuscular Placement of Prosthetic Balloons and Reservoirs.

INTRODUCTION: Synchronous ipsilateral high submuscular placement of artificial urinary sphincter (AUS) pressure-regulating balloons (PRBs) and inflatable penile prosthesis (IPP) reservoirs in a single submuscular tunnel is a novel strategy that could be advantageous for patients who have had major pelvic surgery. AIM: To report our initial experience with synchronous ipsilateral vs bilateral placement of AUS PRBs and IPP reservoirs in men undergoing implant surgery. METHODS: We retrospectively reviewed all patients undergoing synchronous AUS and IPP placement from 2007 through 2015 by a single surgeon at our tertiary center. Patients were stratified according to ipsilateral vs bilateral placement of the AUS PRB and IPP reservoir. MAIN OUTCOME MEASURES: Reoperation rates because of infectious or erosive complications and mechanical failure were assessed. RESULTS: Of the 968 implant surgeries during the study period, 47 men had synchronous device placement, of whom 17 (36%) underwent ipsilateral placement of the PRB and reservoir. During a median follow-up of 19 months (range = 1-84 months), reoperations were necessary in 12 of 47 (26%) and were similar between groups (ipsilateral, 5 of 17, 29%; bilateral, 7 of 30, 23%; P = .73). Most reoperations were due to AUS-related complications (10 of 12, 83%) and nearly all patients with reoperation (10 of 12, 83%) had compromised urethras (ie, prior urethral surgery, radiation, or prior AUS implantation). The most common indication for reintervention was cuff erosion (4 of 47, 9%), with no difference between groups (ipsilateral, 3 of 17, 18%; bilateral, 1 of 30, 3%; P = .13). CONCLUSION: Synchronous ipsilateral high submuscular placement of urologic prosthetic balloons could safely facilitate prosthetic surgery in patients with a history of major pelvic and inguinal surgery.

Preoperative Urine Culture Results Correlate Poorly With Bacteriology of Urologic Prosthetic Device Infections.

INTRODUCTION: Although preoperative negative urine culture results and treatment of urinary tract infections are generally advised before artificial urinary sphincter (AUS) and penile prosthesis (PP) surgery to prevent device infection, limited evidence exists to support this practice. AIM: To evaluate the relation between preoperative urine culture results and the bacteriology of prosthetic device infections. METHODS: Men undergoing AUS and/or PP placement at a tertiary referral center from 2007 through 2015 were analyzed. A total of 713 devices were implanted in 681 patients (337 AUSs in 314 patients and 376 PPs in 367 patients), of whom 259 (36%) did not have preoperative urine culture and were excluded. The remaining 454 patients received standard broad-spectrum perioperative antibiotics. Two patient groups were identified based on preoperative urine cultures: group 1 had negative urine culture results and group 2 had untreated asymptomatic positive urine culture results identified postoperatively. MAIN OUTCOME MEASURES: Device infection was diagnosed clinically and cultures obtained from the explanted device and tissue spaces were compared with preoperative urine culture results. RESULTS: Although multivariate analysis showed that patients undergoing AUS placement had a 4.5-fold greater risk of positive urine culture results (114 of 250, 45%) compared with those undergoing PP placement (36 of 204, 18%; P < .001), infection rates between device types were similar (8 of 250 for AUSs [3%] and 7 of 204 for PPs [3%]; P = .89). At a median follow-up of 15 months, device infection occurred in 15 of 454 devices (3%) implanted and no differences in infection rates were noted between urine culture groups (10 of 337 in group 1 [3.3%] and 5 of 117 in group 2 [4.3%]; P = .28). Remarkably, only 1 of 15 device infections (7%) had the same organism present at preoperative urine culture. CONCLUSIONS: Despite the finding that patients with AUS placement had a 4.5 times higher rate of positive urine culture results than patients with PP placement, preoperative urine culture results appeared to show little correlation with the bacteriology of prosthetic device infections.

Prolapse repair with and without apical resuspension-Practice patterns among certifying American urologists.

AIMS: To examine surgeon characteristics in certifying urologists performing prolapse surgeries. Anterior compartment prolapse is often associated with apical prolapse, with high rates of recurrence when anterior repair is performed without apical resuspension. METHODS: Six-month case log data of certifying urologists between 2003 and 2013 was obtained from the American Board of Urology (ABU). Cases with a CPT code for common prolapse repairs in females ≥18 years were analyzed. RESULTS: Among 2,588 urologists logging at least one prolapse surgery and a total of 30,983 surgeries, 320 (1.0% of all cases) uterosacral ligament suspension, 3,673 (11.9%) sacrospinous ligament suspension, and 2,618 (8.4%) abdominal sacrocolpopexy were identified. The remaining 14,585 cases were logged as anterior repair. 54.7% of anterior repairs did not include apical suspension. The proportion of anterior repairs without apical suspension has decreased from 77.7% in 2004 to 41.4% in 2012 (P < 0.001). Female subspecialists before 2011 performed anterior repair without apical suspension in 58.5%, versus 70.3% by all others. Since 2011 there has been a decrease in number of anterior repairs without apical suspension, notably in those applying for Female Pelvic Medicine and Reconstructive Surgery (FPMRS) certification (17.1% vs. 30.7% by all other urologists, P < 0.001); nonacademically affiliated urologists are 2.1 times more likely to report anterior repair without apical suspension than academically affiliated colleagues (P < 0.001). CONCLUSIONS: The proportion of prolapse repairs reported as anterior repairs without apical suspension is decreasing, although it remains a substantial portion. Recent log year, FPMRS, and academic affiliation were associated with prolapse repairs addressing apical support. Neurourol. Urodynam. 36:344-348, 2017. © 2015 Wiley Periodicals, Inc.

Disparities in female urologic case distribution with new subspecialty certification and surgeon gender.

AIMS: To examine surgical case volume characteristics in certifying urologists associated with common female urologic procedures to evaluate the practice patterns, given the recent establishment of subspecialty certification in Female Pelvic Medicine and Reconstructive Surgery (FPMRS) and changes in urologist gender composition. METHODS: Six-month case log data of certifying urologists (2003-2013) was obtained from the American Board of Urology (ABU). We examined case logs for 26 CPT codes for common female urologic procedures focused on four procedure groups: incontinence, prolapse, vesicovaginal fistula (VVF), and revision/removal of vaginal mesh/graft. RESULTS: Among 4802 urologists logging at least one female urology case, 43,949 (55.6% of all cases) incontinence, 30,983 (39.2%) prolapse, 451 (0.6%) VVF, and 3643 (4.6%) revision of mesh/graft surgeries were identified. While 90.8% logging at least one female CPT code were men, women surgeons (9.2%) accounted for a disproportionate volume (22.6%) of cases. With initiation of the FPMRS subspecialty certification in 2011, 225 FPMRS candidates (out of 1716 certifying urologists) were identified, compared to 367 (out of 3828 certifying urologists) female subspecialists prior to 2011. FPMRS accounted for 56.7% of prolapse, 62.9% VVF, 59.0% mesh/graft revisions, and 41.9% of incontinence surgeries, compared to female specialists before 2011 (39.1%, 42.4%, 41.5%, and 21.6% respectively (all P < 0.001)). CONCLUSIONS: A growing proportion of female urologic cases are performed by female subspecialists, with a significant increase since initiation of FPMRS subspecialty certification. Women surgeons account for a disproportionate volume of these cases despite remaining a minority of certifying urologists and female subspecialists. Neurourol.

Is Risk of Artificial Urethral Sphincter Cuff Erosion Higher in Patients with Penile Prosthesis?

INTRODUCTION: Frequently encountered morbidities after prostatectomy include stress urinary incontinence and erectile dysfunction. Patients with severe disease may undergo placement of both a penile prosthesis (PP) and an artificial urethral sphincter (AUS). AIM: We hypothesized that concomitant PP may promote AUS cuff erosion by impaired corporal blood flow and/or direct pressure on the cuff. The aim of this study was to compare the rate of AUS cuff erosion in patients with and without a PP. METHODS: We reviewed 366 AUS operations at our tertiary center between 2007 and 2015 with a mean follow-up of 41 months (range 6-104). Included in the analysis were first-time AUS cuff erosions. Patients with recurrent erosions, AUS revisions, and iatrogenic erosions were excluded. In a separate analysis, we analyzed AUS explantations for all causes. Cohorts were compared by demographic information, preoperative characteristics, and rates of erosion and explantation. MAIN OUTCOME MEASURES: Erosion confirmed by cystourethroscopy and explantation of the AUS for all causes. RESULTS: Among 366 AUS surgeries at a mean follow-up of 41 months, there were 248 (67.8%) AUS alone cases compared to 118 (32.2%) AUS and PP cases (AUS/PP). Sixty-two patients met exclusion criteria for first-time cuff erosion. Among 304 evaluable AUS patients, we found a significantly higher rate of erosion in the AUS/PP group (11/95, 11.6%) compared to the AUS alone group (9/209, 4.3%, P = .037). When examining explantations for all causes in the entire cohort (n = 366), we observed a significantly higher rate of device removal, (20/118, 17%) in the AUS/PP group compared to the AUS group (23/248, 9.2%, P = .044). CONCLUSION: AUS/PP patients appear to have a higher risk of AUS cuff erosion and explantation compared to men with AUS alone.
