Abstract
Background The Infectious Diseases Society of America (IDSA) developed the Core Antimicrobial Stewardship (AS) Curriculum to meet the increasing demand for infectious diseases (ID) providers with AS expertise. Notable diversity in implementation approaches has been observed among ID fellowship programs using the curriculum. We sought to describe individual approaches and develop a curriculum implementation roadmap. Methods We surveyed ID fellowship programs that had previously implemented the IDSA Core AS curriculum. The survey included questions regarding program characteristics, curriculum participants and presentation format, resources and barriers, and implementation strategies. Commonly reported program features were summarized in the context of the self-reported implementation strategies. Implementation guides were developed based on the most common characteristics observed. Results Of 159 programs that had purchased the curriculum, 37 responded, and 34 (21%) were included in the analysis. The curriculum was primarily taught by AS physicians (85%) and AS pharmacists (47%). The most common conference structure was a longitudinal conference series (32%), and eLearning was the most common presentation format. Limited AS faculty time (76%) and limited first-year fellow availability (62%) were frequently reported as barriers, and dedicated AS curricular time was a resource available to most programs (67%); implementation guides were created for these 3 program features. Conclusions Programs reported a variety of implementation barriers and resources, with several common themes emerging, allowing for the development of tailored curriculum planners for 3 commonly observed program characteristics. This work will equip fellowship programs with curriculum implementation strategies and guide future enhancements of the IDSA Core and Advanced AS curricula.

[PMID: 39197557 DOI: 10.1016/j.urology.2024.08.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 08/08/2024] [Accepted: 08/20/2024] [Indexed: 09/01/2024]
Abstract
OBJECTIVE To compare anesthetic parameters using a novel prone single transverse chest roll technique (STR) to the standard thoraco-pelvic dual transverse roll technique (DTR). METHODS A retrospective review of 441 patients who underwent PCNL between 2018 and 2022 was performed. A total of 4 surgeons were included-surgeon 1 utilized the STR technique while surgeons 2, 3, and 4 used the DTR technique. Anesthetic parameters including end-tidal CO2 (ETCO2), mean arterial pressure (MAP), peak airway pressure (Ppeak), plateau airway pressure (Pplat), positive end-expiratory pressure (PEEP), oxygen saturation (SpO2), and tidal volume (TV) were compared between both groups at 0 (supine), 15-, 30-, and 60-minute post-intubation intervals. Mixed effects regression models with interaction and pairwise comparisons were made between both groups (P <.05). RESULTS A total of 581 PCNLs were performed with 199 using STR and 382 using DTR. Surgery duration, ASA class, and age were similar amongst the STR and DTR groups. Estimated blood loss (59cc vs 83cc, P = .007) and length of stay (77 hrs vs 163 hrs, P = <.001) was significantly lower in the STR group. There was a significantly lower Ppeak, Pplat and TV in the STR compared to DTR group at 0, 15, 30, and 60 minutes (P <.001). CONCLUSION Usage of a single transverse chest roll during prone PCNL appears to be a safe positioning method. STR patients had lower Ppeak and Pplat at all time points, which has been shown to be predictive of lower blood loss.

Abstract
BACKGROUND To evaluate contemporary preoperative risk factors and subsequent postoperative management of incidental prostate cancer (iPCa) and incidental clinically significant prostate cancer (icsPCa, Grade Group [GG] ≥ 2 PCa). METHODS A retrospective cohort of 811 men undergoing Holmium enucleation of the prostate (HoLEP) (January 2021-July 2022) were identified. Advanced preoperative testing was defined as prostate health index (PHI), prostate MRI, and/or negative preoperative biopsy. Descriptive statistics (Whitney-Mann U test, Chi-squared test) and multivariable logistic regression were performed. RESULTS iPCa and icsPCa detection rates were 12.8% (104/811) and 4.4% (36/811), respectively. Advanced preoperative testing (406/811, 50%) was associated with younger age and higher (prostate specific antigen) PSA, prostate volume, and PSA density. On multivariable analysis, PHI ≥ 55 was associated with iPCa (OR 6.91, 95% CI 1.85-26.3, p = 0.004), and % free PSA (%fPSA) was associated with icsPCa (OR 0.83, 95% CI 0.67, 0.94, p = 0.01). GG1 disease comprised the majority of iPCa (65%, 68/104) with median 1% involvement. iPCa patients were followed with active surveillance (median follow up 9.3 months), with higher risk patients receiving prostate MRI and confirmatory biopsy. Three patients proceeded to radical prostatectomy or radiation. CONCLUSIONS In the era of MRI and advanced biomarkers, the majority of iPCa following HoLEP is low volume GG1 suitable for active surveillance. A tentative follow-up strategy is proposed. Patients with PHI ≥ 55 or low %fPSA, even with negative prostate MRI, can consider preoperative prostate biopsy before HoLEP.

Abstract
INTRODUCTION We aimed to compare holmium laser enucleation of the prostate (HoLEP) outcomes in patients with and without neurologic diseases (ND). METHODS A prospectively maintained database of patients undergoing HoLEP from January 2021 to April 2022 was reviewed. The following ND s were included: diabetes-related neuropathy/neurogenic bladder, Parkinson's disease, dementia, cerebrovascular accident, multiple sclerosis, traumatic brain injury, transient ischemic attack, brain/spinal tumors, myasthenia gravis, spinal cord injury, and other. Statistical analysis was performed using t-tests, Chi-squared, and binomial tests (p<0.05). RESULTS A total of 118 ND patients were identified with 135 different neurologic diseases. ND patients were more likely to have indwelling catheters (57% vs. 39%, p=0.012) and urinary tract infections (UTIs) preoperatively (32% vs. 19%, p=0.002). Postoperatively, ND patients were more likely to fail initial trial of void (20% vs. 8.1%, p<0.001) and experience an episode of acute urinary retention (16% vs. 8.5%, p=0.024). Within 90 days postoperative, the overall complication rate was higher in the ND group (26% vs. 13%, p=0.001). Within the ND group, 30/118 (25%) had ≥1 UTI within 90 days preoperative, which decreased to 10/118 (8.7%) 90 days postoperative (p<0.001). At last followup (mean 6.7 months [ND] vs. 5.4 months [non-ND], p=0.03), four patients (4.4%) in the ND group required persistent catheter/clean intermittent catheterization compared to none in the non-ND group (p=0.002). CONCLUSIONS Patients with ND undergoing HoLEP are more likely to experience postoperative retention and higher complication rates compared to non-ND patients. While UTI rates are higher in this population, HoLEP significantly reduced three-month UTI and catheterization rates.

Early PSA decline after starting second-generation hormone therapy in the post-docetaxel setting predicts cancer-specific survival in metastatic castrate-resistant prostate cancer. Prostate Cancer Prostatic Dis 2024; 27:334-338. [PMID: 37935879 DOI: 10.1038/s41391-023-00751-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 09/07/2023] [Accepted: 10/19/2023] [Indexed: 11/09/2023]
Abstract
BACKGROUND The objective of this study was to evaluate the prognostic value of early PSA decline following initiation of second-generation hormone therapy (2nd HT), namely abiraterone acetate or enzalutamide, in patients with taxane-refractory metastatic castrate-resistant prostate cancer (mCRPC) and evaluate utility of this metric in informing intensified surveillance/imaging protocols. METHODS We retrospectively identified 75 mCRPC patients treated with 2nd HT following docetaxel failure (defined as PSA rise and radiographic progression). Patients were categorized patients into two cohorts based on the first PSA within 3 months after initiation of therapy: PSA reduction ≥50% (Group A) and PSA reduction <50% (Group B). The primary endpoint was cancer-specific mortality (CSM). The secondary endpoint was radiographic disease progression (rDP) on 2nd HT. In univariate and multivariate analyses, we investigated factors associated with rPD and CSM. RESULTS We included 75 patients (52 in Group A, 23 in Group B) in the analytic cohort. Baseline clinico-demographic characteristics, including median age, primary Gleason score risk group, median pre-treatment PSA, disease burden, site of metastases, and pre-treatment ECOG score were not statistically different between the two groups. Median follow up time was 30 months and the median time to radiographic disease progression was 28.1 and 12.5 months (p = 0.002) in cohorts A and B, respectively. On univariate and multivariate analyses, both PSA reduction ≥50% and volume of metastatic disease were significantly associated with a decreased risk of radiographic disease progression (HR 0.41, 95% CI 0.21-0.80, p = 0.0113) as well as a decreased risk of cancer-specific mortality (HR 0.29, 95% CI 0.09-0.87, p = 0.0325). CONCLUSION PSA reduction ≥50% within 3 months of starting 2nd HT was associated with significantly improved radiographic disease progression-free survival and 3-year cancer-specific mortality. This suggests using PSA 50%-decline metric in surveillance patients with on 2nd HT and identifies patients who require further evaluation with imaging.

Abstract
AIM To characterise the corticoreticular pathway (CRP) in a case-control cohort of adolescent idiopathic scoliosis (AIS) patients using high-resolution slice-accelerated readout-segmented echo-planar diffusion tensor imaging (DTI) to enhance the discrimination of small brainstem nuclei in comparison to automated whole-brain volumetry and tractography and their clinical correlates. MATERIALS AND METHODS Thirty-four participants (16 AIS patients, 18 healthy controls) underwent clinical and orthopaedic assessments and brain magnetic resonance imaging (MRI) on a 3 T MRI machine. Automated whole-brain volume-based morphometry, tract-based spatial statistics analysis, and manual CRP tractography by two independent raters were performed. Intra-rater and inter-rater agreement of DTI metrics from CRP tractography were assessed by intraclass correlation coefficient. Normalised structural brain volumes and DTI metrics were compared between groups using Student's t-tests. Linear correlation analysis between imaging parameters and clinical scores was also performed. RESULTS AIS patients demonstrated a significantly larger pons volume compared to controls (p=0.006). Significant inter-side CRP differences in mean (p=0.02) and axial diffusivity (p=0.01) were found in patients only. Asymmetry in CRP fractional anisotropy significantly correlated with the Cobb angle (p=0.03). CONCLUSION Relative pontine hypertrophy and asymmetry in CRP DTI metrics suggest central supranuclear inter-hemispheric imbalance in AIS, and support the role of the CRP in axial muscle tone. Longitudinal evaluation of CRP DTI metrics in the prediction of AIS progression may be clinically relevant.

Abstract
Introduction: Holmium laser enucleation of the prostate (HoLEP) is routinely performed with a 24F, 26F, or a 28F scope. Proponents of the larger scopes propose that a bigger sheath size allows for superior flow and visibility leading to a more efficient operation and better hemostasis. Those utilizing the smaller scopes suggest that the smaller sheath is less traumatic, resulting in lower stricture rates and temporary incontinence. We sought to compare outcomes of ambulatory HoLEP using the 24F and 28F laser scope. Materials and Methods: From May 2022 to March 2023, we randomized patients undergoing HoLEP (<200 cm3 in size) 1:1 to either a 24F or 28F scope. The primary outcome was differences in surgical duration between groups (minutes). Secondary outcomes included surgeon scope evaluation and postoperative patient results. Results: There was no difference in patient characteristics in those randomized to 28F (n = 76) vs 24F (n = 76) (p > 0.05) scopes. Procedural duration and efficiencies were not different between groups (all p > 0.05). The 28F scope was associated with improved surgeon-graded irrigation flow and visibility (p < 0.001). Patients treated with the 28F scope were more likely to achieve effective same-day trial of void (SDTOV) (28F 94.3% vs 24F 82.1%, p = 0.048) and have a shorter length of stay (LOS) (28F 7.0 vs 24F 11.9 hours, p = 0.014), however, rates of same-day discharge (SDD) were not statistically different (28F 87.8% vs 24F 78.4%, p = 0.126). There was no difference between the cohorts in rates of 90-day emergency room presentations, re-admissions, complications, or functional ouctomes (p > 0.05). Conclusions: We identified no clear advantage of scope size with regard to intraoperative or postoperative outcomes at 3-month follow-up due to scope size. However, if SDD is part of your postoperative pathway, the 28F scope may shorten LOS and increase rates of effective SDTOV. Clinicaltrials.gov: NCT05308017.

Abstract
INTRODUCTION Prostatic urethral lift (PUL) accounts for approximately one-quarter of all surgical benign prostatic hyperplasia (BPH) procedures performed in the U.S. Within five years of a patient's PUL procedure, approximately 1/7 patients will require surgical BPH retreatment. We aimed to highlight the evidence of surgical BPH retreatment modalities after PUL, with a focus on safety, short-term efficacy, durability, and relative costs. METHODS A literature review was performed using PubMed, and an exhaustive review of miscellaneous online resources was completed. The search was limited to English, human studies. Citations of relevant studies were reviewed. RESULTS No study has examined the efficacy, safety, or durability of transurethral resection of the prostate (TURP) or repeat PUL in the post-PUL setting. Recently, groups have examined laser enucleation (n=81), water vapor thermal therapy (WVTT) (n=5), robotic simple prostatectomy (SP) (n=2), and prostatic artery embolization (PAE) (n=1) in the post-PUL setting. Holmium enucleation of the prostate (HoLEP) after PUL appears to be safe and has similar functional outcomes to HoLEP controls. Other treatment modalities examined appear safe but have limited efficacy evidence supporting their use. Photo-selective vaporization of the prostate (PVP) and robotic waterjet treatment (RWT) have no safety or efficacy studies to support their use in the post-PUL setting. CONCLUSIONS Despite increasing numbers of patients expected to require surgical retreatment after PUL in North America, there is currently limited evidence and a lack of recommendations guiding the evaluation and management of these patients. HoLEP is associated with the strongest evidence to support its use in the post-PUL setting.

Abstract
Introduction: Holmium laser enucleation of the prostate (HoLEP) has evidenced-based advantages in treating benign prostatic hyperplasia (BPH) relative to other interventions. Unfortunately, the adoption of HoLEP has remained relatively low in Medicare and the National Surgical Quality Improvement Program populations. HoLEPs role as an inpatient surgical intervention is changing as advancements in the technique and systems have demonstrated the feasibility of same-day discharge. Thus, our objective was to evaluate national HoLEP trends in ambulatory surgery settings from 2016 to 2019. Materials and Methods: The Nationwide Ambulatory Surgery Sample (NASS) is the largest national all-payer database of ambulatory surgical encounters, managed by the Agency for Healthcare Research and Quality. A cross-sectional retrospective analysis of the 2016 and 2019 NASS was performed. Rates of BPH surgeries were calculated and stratified by age, census region, and primary payer to compare across time points for trends. Chi-squared tests and two-sample t-tests were completed for categorical and continuous variables, respectively. Results: The total number of ambulatory BPH surgeries fell 20% between 2016 (n = 124,538) and 2019 (n = 100,593). In 2016, HoLEP lagged behind photoselective vaporization of the prostate (PVP) and transurethral resection of prostate (TURP) with 4.7% of surgeries but rose to the second most common procedure in 2019 with 8.3% of total surgeries. TURP was the most common intervention (62.6% in 2016, 90.7% in 2019). Simple prostatectomy was the most expensive intervention. By U.S. census region, more HoLEPs were carried out in the South (43.1% in 2016, 37.5% in 2019) and Midwest (26.8% in 2016, 31.7% in 2019). Conclusions: Overall, HoLEP uptake is increasing. HoLEP has replaced greenlight PVP as the second most frequently used intervention. The rate of ambulatory HoLEPs has nearly doubled despite a general decrease in the number of surgeries.

Abstract
Introduction: The effect of prophylactic bladder neck incision (BNI) at time of holmium laser enucleation of the prostate (HoLEP) is unknown. The aim of our study was to examine HoLEP outcomes with a specific focus on rates of bladder neck contractures (BNCs), with and without utilizing prophylactic BNI. Materials and Methods: We performed a retrospective review of HoLEP patients from January 2021 until January 2022. Outcomes of patients who underwent BNI at time of HoLEP were compared with those who underwent standard HoLEP alone. Student's t-tests, chi-square tests, and logistic regressions were performed using SAS Studio. Results: In total, 421 patients underwent HoLEP. BNI was concurrently performed in 74 (17.6%) HoLEP patients. BNI patients were younger (67.5 ± 9.0 years vs 71.1 ± 8.2 years, p = 0.00007) and had smaller prostates (60.7 ± 30.3 cc vs 133.2 ± 64.5 cc, p < 0.0001). Procedure, enucleation, and morcellation times were shorter in the BNI group (all p < 0.0001). There was no statistical difference in same-day discharge rates (90.4% vs 87.7%, p = 0.5), short-term functional outcomes, emergency department (ED) visits, or readmission rates between the two groups. At 14 months mean follow-up, two BNCs occurred in patients in the control group (0.6%), and no BNCs occurred in patients who underwent BNI (0.0%, p = 0.5). Conclusions: BNI at time of HoLEP did not decrease the ability to achieve same-day discharge or increase 90-day complications, ED visits, or readmission rates. No BNCs occurred in patients who underwent prophylactic BNI (0.0%) despite a smaller gland size and lower specimen weight in this cohort. Further prospective studies are required to conclude if concurrent BNI at time of HoLEP is protective against BNC.

Abstract
OBJECTIVE To evaluate if implementation of a percutaneous nephrolithotomy (PCNL) equipment whiteboard can improve communication accuracy of surgical equipment, streamline operative efficiency, and decrease unnecessary case equipment costs. METHODS A real-time editable equipment whiteboard was designed and implemented for all PCNL cases between October and December 2021. The relative difference in pre- and post-intervention surgical equipment accuracy as well as overall case costing was compared from 90 days prior to implementation to the period after intervention. RESULTS Quality assessment surveys were completed prior to whiteboard implementation (N = 25) and cost implementation (n = 15). Pre- and postoperative assessment of equipment communication, assessed on a 10-point scale, improved after implementation of the communication whiteboard (Pre-op: 6.7/10 vs. 8.9/10, P < .001. Post-op: 7.0/10 vs. 9.3/10, P < .001). On average 64% (3.2/5) of items were accurate on preintervention cases. Postintervention accuracy improved to 88% (4.4/5 items) (P = .049). There was a significant relative case cost improvement after implementing the PCNL equipment whiteboard with an average of $436.81 USD savings per case (P = .001) and $488.22 USD per renal moiety (P = .002). CONCLUSION Our baseline quality assessment of surgical team communication regarding PCNL equipment identified an area for improvement. Multidisciplinary feedback resulted in the development of a real-time editable PCNL equipment whiteboard which improved team perception of equipment communication, case item accuracy and resulted in a relative average cost savings for PCNL.

Abstract
Introduction: Intradetrusor onabotulinumtoxinA (OTA) injection is a well-established treatment option for refractory overactive bladder; however, its use at the time of holmium laser enucleation of the prostate (HoLEP) for men with bladder outlet obstruction (BOO) and severe storage symptoms has not been previously reported. Materials and Methods: We retrospectively identified men with BOO and severe storage symptoms who underwent treatment with 200 U of intradetrusor OTA (Botox®) at the time of HoLEP. Patients were propensity score matched to a cohort of HoLEP-only patients based on age, Michigan Incontinence Symptom Index (M-ISI) score, preoperative urinary retention, urge incontinence, and prostate size. Perioperative, postoperative, and patient-reported outcomes were examined between groups. Results: We identified 82 men who underwent HoLEP, including 41 patients in the OTA group and 41 patients in the control group. There was no difference in operative times (59 minutes OTA vs 55 minutes control, p = 0.2), rates of same-day trial of void (TOV) (92% OTA vs 94% control, p = 0.7), or rates of same-day discharge (88% OTA vs 85% control, p = 0.6) between groups. There was no difference in temporary postoperative urinary retention (7% OTA vs 2% control, p = 0.3) between groups. Patients who received OTA injections had a significant reduction in their incontinence scores at 3-month follow-up (M-ISI -8, interquartile range [IQR]: -13 to 0, p < 0.001), whereas control patients did not (M-ISI -5, IQR: -8 to -1, p = 0.2). There was no difference in rates of 90-day complications between groups (OTA 10% vs control 5%, p = 0.7). Conclusions: Intradetrusor OTA at the time of HoLEP is safe and is associated with improved urinary incontinence scores and AUA Symptom Score. Rates of same-day discharge and same-day TOV after HoLEP were not affected by OTA. These findings support the role of OTA as an adjunct to surgical intervention in men with incontinence in the presence of BOO.

Urology 2023; 173:180-186. [PMID: 36586427 DOI: 10.1016/j.urology.2022.12.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 11/13/2022] [Accepted: 12/14/2022] [Indexed: 12/29/2022]
Abstract
OBJECTIVE To compare perioperative outcomes between Holmium laser enucleation of the prostate (HoLEP), open simple prostatectomy (OSP), and robotic simple prostatectomy (RSP) for large prostates (> 80 cc). MATERIALS AND METHODS A retrospective study of 340 patients who underwent HoLEP (n = 209), OSP (n = 66), or RSP (n = 65) at a large academic medical center between January 2013 - September 2021 was performed. Length of stay (LOS), operative time, catheter duration, estimated blood loss (EBL), blood transfusion, and 30-day ED visits and readmissions were compared between the three groups. Univariate analyses consisted of ANOVA with Tukey's corrections and Chi-square tests. Linear and multivariate logistic regression was also performed. All tests were two-sided and a p-value <0.05 was pre-determined to be statistically significant. Analyses were performed with SAS v9.4. RESULTS HoLEP was found to have the shortest: operative time (1.4 vs 2.7 vs 3.8h), LOS (0.65 vs 4.2 vs 2.6d), and catheter duration (0.38 vs 9.9 vs 11.2d) compared to OSP and RSP, respectively (all P <.0001). HoLEP also had the lowest EBL (66 vs 795 vs 326 mL, P <.0001). HoLEP and RSP had a lower risk of blood transfusion compared to OSP (P <.0001). These associations remained significant on multivariable analyses. CONCLUSION HoLEP is a minimally invasive treatment option for large prostates that was found to have shorter operative time, LOS, and catheter duration as well as lower EBL compared to OSP and RSP.

Abstract
Introduction: Tranexamic acid (TXA) is a clot promoting agent utilized during orthopedic procedures to decrease bleeding. Urologists have demonstrated the benefits of TXA in percutaneous surgery. Our objective was to assess the safety and efficacy of single-dose TXA on same-day holmium laser enucleation of the prostate (HoLEP) outcomes. Methods: From September 2021 to January 2022, we prospectively randomized 110 patients undergoing HoLEP to either 1 g of TXA after induction or no treatment. Institutional Review Board (IRB) approval (STU00215134) and registry with ClinicalTrials.gov (NCT05082142) were obtained before enrollment. Primary outcome was the rate of effective same-day discharge (SDD). Secondary outcomes included transfusion rate, same-day catheter removal, length of stay (LOS), and 90-day complications. Power analysis determined that 110 patients should be enrolled to detect a 25% difference in SDD rate. Results: There was no difference in patient demographic and prostate features between the control (n = 55) and TXA groups (n = 55; all p > 0.05). The overall rate of effective SDD was not different between the control and TXA groups (49/55 [89%] vs 51/55 [93%], p = 0.74). Median LOS (hh:mm) was not different between groups (03:07 vs 02:50, p = 0.23) with only 3/110 (2.7%) having an LOS >24 hours. Effective same-day catheter removal occurred in 99/110 (90%) patients with no difference between groups (49/55 vs 50/55, p = 0.99). There was no difference in operative parameters (time, energy, specimen weight) and postoperative complications between groups (all p > 0.05). No patients required transfusions and there were no major 90-day complications related to surgery (Clavien-Dindo ≥IIIb). Conclusion: TXA administration is safe but did not impact SDD after HoLEP.

Abstract
Abstract
Background
Little is known about antimicrobial prescribing when patient care is transitioned to comfort measures only (CMO). We used a multi-disciplinary survey and retrospective chart review to gain insight into antimicrobial prescribing in this population at an academic medical center.
Methods
A survey focusing on antimicrobial prescribing during the transition to CMO was electronically distributed to providers in Infectious Disease, Pulmonary/Critical Care, Hematology/Oncology, Palliative Care, and Hospital Medicine, and responses were compared across divisions. A retrospective chart review was performed of patients admitted to Beth Israel Deaconess Medical Center in 2020 who were on antimicrobials in the 48 hours prior to CMO. We investigated the frequency of patients on antimicrobials after the transition to CMO and provider rationale for continuing antimicrobials.
Results
We received 113 survey responses for a response rate of 35%; 111 were included for analysis. 41% of respondents indicated that they “sometimes” or “often” continued an antimicrobial during the transition to CMO. Of the 546 patient charts reviewed, 140 (26%) patients were alive 48 hours after CMO order, and 19 (14%) of those patients remained on antimicrobials (Figure 1).
Patient/family preference was the most common factor when deciding whether to continue antimicrobials in patients on CMO, identified by 77% of respondents (Figure 2). 5/19 (26%) patients who were alive on antimicrobials 48 hours after CMO had documentation that antimicrobials were continued due to patient/family preference.
Symptom palliation was the second most common factor when deciding whether to continue antimicrobials in patients on CMO, identified by 62% of respondents. For patients already on symptom directed medications, many providers perceived antibiotics to be helpful to palliate symptoms, though there were inter-division differences (Table 1). 5/19 (26%) patients who were alive on antimicrobials 48 hours after CMO had documentation that antimicrobials were continued for palliation of symptoms.
Perceived Helpfulness of Antimicrobials for Specific Symptoms by Division
Number/percentage of survey responses indicating antimicrobials were at least somewhat helpful for specified symptoms in patients already on symptom directed medications. Divisions compared using Kruskal-Wallis Tests.
Conclusion
Even after transition to CMO, a substantial number of patients remain on antimicrobials. Patient/family preference and symptom palliation are important factors when continuing antimicrobials in this population.

Abstract
INTRODUCTION To improve surgeon-patient communication of postoperative expectations, a multidisciplinary team created and evaluated a holmium laser enucleation of the prostate (HoLEP) expectations handout. Although an effective benign prostatic hyperplasia (BPH) surgery, it is crucial that patients understand the HoLEP recovery. A quality assessment previously performed at our center revealed 11% of patients were not aware of potential ejaculate volume changes. METHODS Patients presenting for consultation prior to HoLEP were assessed with post-procedure patient-reported outcomes (PRO) questionnaires before (n=50) and after (n=50) the implementation of a surgeon-patient expectations handout. Patient demographics and perioperative course were examined in the context of responses. Comparisons were made with a Chi-squared test (p<0.05). RESULTS We observed a response rate of 96% (pre-handout: 46/50 vs. post-handout: 50/50). Overall, 89/96 (93%) patients felt they had a reasonable understanding of HoLEP expectations, with no difference between cohorts (45/46 vs. 48/50, p=0.71). There was no difference in reporting an understanding of post-HoLEP hematuria (p=0.12) or urinary incontinence (UI) (p=0.99). The implementation of the handout improved understanding of retrograde ejaculation (pre-handout: 41/46 vs. post-handout: 50/50, p=0.022) and dysuria (pre-handout: 35/46 vs. post-handout: 46/50, p=0.048). Fifty-five patients experienced any dysuria postoperatively, with 89% reporting less than or equal to what they expected. Close to 30% (28/94) of respondents offering ways to improve communication suggested an educational website. CONCLUSIONS The implementation of a surgeon-patient handout during HoLEP consultation improved understanding of postoperative retrograde ejaculation and dysuria at our center. We identified areas for future technology-aided improvements in post-HoLEP communication.

Abstract
Shock wave lithotripsy (SWL) is an effective and commonly applied clinical treatment for human kidney stones. Yet the success of SWL is counterbalanced by the risk of retained fragments causing recurrent stone formation, which may require retreatment. This study has applied GeoBioMed experimental and analytical approaches to determine the size frequency distribution, fracture patterns, and reactive surface area of SWL-derived particles within the context of their original crystal growth structure (crystalline architecture) as revealed by confocal autofluorescence (CAF) and super-resolution autofluorescence (SRAF) microscopy. Multiple calcium oxalate (CaOx) stones were removed from a Mayo Clinic patient using standard percutaneous nephrolithotomy (PCNL) and shock pulse lithotripsy (SPL). This produced approximately 4-12 mm-diameter PCNL-derived fragments that were experimentally treated ex vivo with SWL to form hundreds of smaller particles. Fractures propagated through the crystalline architecture of PCNL-derived fragments in a variety of geometric orientations to form rectangular, pointed, concentrically spalled, and irregular SWL-derived particles. Size frequency distributions ranged from fine silt (4-8 μm) to very fine pebbles (2-4 mm), according to the Wentworth grain size scale, with a mean size of fine sand (125-250 μm). Importantly, these SWL-derived particles are smaller than the 3-4 mm-diameter detection limit of clinical computed tomography (CT) techniques and can be retained on internal kidney membrane surfaces. This creates clinically undetectable crystallization seed points with extremely high reactive surface areas, which dramatically enhance the multiple events of crystallization and dissolution (diagenetic phase transitions) that may lead to the high rates of CaOx kidney stone recurrence after SWL treatment.

Abstract
Abstract
Background
Combining the artificial intelligence algorithm with the known clinical risk factors may provide enhanced accuracy for prediction of the hidden atrial fibrillation (AF) in patients with embolic stroke with undetermined source (ESUS).
Purpose
We aimed to develop enhanced prediction models for AF with deep learning algorithm (DLA) and clinical predictors in patients with ESUS. The DLA was created to identify the patients with paroxysmal AF based on their electrocardiograms (ECG) during sinus rhythm.
Methods
We analyzed the 221 patients who underwent insertable cardiac monitor (ICM) for AF detection following ESUS. The DLA was previously developed with sinus rhythm ECGs of 10,605 paroxysmal AF patients and 50,522 non-AF patients. The convolutional neural network was used for the DLA. The primary endpoint was defined as any AF episode lasting over 5 min by ICM. The atrial ectopic burden (AEB) was calculated as the percentage of the number of conducted QRS by atrial ectopy on Holter monitoring.
Results
AF (≥5 min) was detected by ICM in 32 patients (14.5%) during follow-up period of 15.1±8.6 months. AF patients had higher AEB (0.199% vs 0.023%, p<0.001), larger left atrial diameters (LAD, 41.2 mm vs 35.7 mm, p<0.001), and larger left atrial volume index (LAVI, 46.4 ml/m2 vs 32.3 ml/m2, p<0.001) than those without AF. The means of calculated probabilities of AF by DLA were higher in patients with AF than those without AF (63.8% vs 40.2%, p<0.001). In the receiver operating characteristic curve analysis, the areas under the curve (AUC) were the highest in DLA (0.824) followed by AEB (0.784), LAVI (0.780), and LAD (0.768). The multivariable model with AEB, LAVI, and DLA demonstrated excellent prediction accuracy for paroxysmal AF (AUC: 0.902, Figure 1)
Conclusions
In patients with ESUS, the DLA outperformed other clinical risk factors for prediction of AF. Combining DLA with AEB, LAD and LAVI could is a potential useful tool to predict AF in ESUS patients.

Abstract
Abstract
Background
Atrial fibrillation (AF) is the most cause of cardioembolic source causing cryptogenic stroke. In these, anticoagulation therapy could reduce recurrence of stroke. However, paroxysmal AF would not be detected even by 24 hours Holter monitoring. Deep learning-based electrocardiogram (ECG) analysis models were recently developed to detect AF during sinus rhythm.
Purpose
We aimed to develop a deep learning algorithm (DLA) to detect AF during sinus rhythm and validate the model in patients with cryptogenic stroke who underwent implantable cardiac monitoring (ICM) to diagnose paroxysmal AF.
Methods
This cohort study involved three hospitals (A, B, and C). We developed a DLA to detect AF using sinus rhythm 10 s 12-lead ECG. We included adult patients aged ≥18 years from hospital A and B. We used development data from AF adult patients who had at least one atrial fibrillation rhythm in the study period (Jan 2016 to Dec 2021) and non-AF patients who had no reference to AF in the ECG and electronic medical record. DLA was based on convolutional neural network (CNN) using 10 s 12-lead. For external validation, the ECGs from 217 patients (hospital C) with cryptogenic stroke who underwent ICM were analyzed by using the DLA for validating the accuracy in the real-world clinical situations.
Results
We included 10,605 AF adult patients and 50,522 non-AF patients as development data. During the internal validation, the area under the curve (AUC) of the final DLA based on CNN was 0.793 (95% Confidence interval 0.778–0.807). In external validation data from cryptogenic stroke patients, the mean ICM duration was 15.1 months, and AF >5 mins was detected in 32 patients (14.5%). The diagnostic accuracy of DLA was 0.793 to detect AF during sinus rhythm, and AUC was 0.824. The sensitivity, specificity, positive predictive value, and negative predictive value of the model were 0.844, 0.784, 0.403, and 0.967, respectively, which outperformed other conventional predictive methods based on clinical factors, such as CHARGE-AF, C2hest, and HATCH.
Conclusions
In this study, DLA accurately detected paroxysmal AF using 12-leads normal sinus rhythm ECG in patients with cryptogenic stroke and outperformed the conventional models. The DLA could be used as a screening tool to identify the cause of stroke in the future.

Abstract
PURPOSE To identify a threshold for intrarenal pressure (IRP), that if exceeded, will result in renal parenchymal damage. Herein, we attempt to identify an IRP threshold by subjecting in vivo porcine kidneys to various levels of extreme pressurized irrigation. Our objective was not to simulate ureteroscopy treatment, but to attempt identify a threshold of IRP injury. METHODS Ten female pigs were intubated and sedated. The abdomen was opened; the ureters were isolated and incised. A LithoVue™ (Boston Scientific) ureteroscope was inserted. A 0-silk tie was then used to tie the ureter around the scope to create a closed system (to achieve a constant level of pressure). Real-time IRPs were measured using the Comet™ Pressure guidewire (Boston Scientific). Kidneys were exposed to pressurized, saline for 36 min (at control, 50, 100, 150 mmHg and higher pressures). Kidneys were then immediately harvested. Two expert histologists independently analyzed kidney slides to identify areas of renal damage. RESULTS The two kidneys exposed to IRPs > 185 mmHg resulted in forniceal rupture and large areas of hematoma. The other IRP groups (control, 50, 100, and 150 mmHg) had no identifiable gross or histologic renal parenchymal damage. CONCLUSIONS No differences in renal parenchymal morphology were identified between pressure groups of control, 50, 100, or 150 mmHg. However, IRPs > 185 mmHg did result in forniceal rupture in this closed-system in vivo porcine model. Further study is required to elucidate the damage threshold.
