This study compared the effects of a conventional approach and a progressive approach to discrete trial teaching when teaching tact relations to 12 children diagnosed with autism spectrum disorder (ASD). The conventional approach was informed by best practice guidelines for teaching receptive and expressive language (Green "Focus on Autism and Other Developmental Disabilities," 16(2), 72-85, 2001; Grow & Leblanc "Behavior Analysis in Practice," 6(1), 56-75, 2013) and other relevant research (e.g., Graff & Karsten "Behavior Analysis in Practice," 5(2), 37-48, 2012; León & Rosales "Journal of Behavioral Education," 27(1), 81-100, 2018; Majdalany et al. "Journal of Applied Behavior Analysis," 47(3), 657-662, 2014). The progressive approach was informed by guidelines outlined by Leaf, Cihon, Leaf, et al. "International Electronic Journal of Elementary Education," 9(2), 361-372, (2016a) and Leaf, Leaf, McEachin, et al. "Journal of Autism & Developmental Disorders," 46(2), 720-731, (2016c). In this study, highly vocal-verbal participants diagnosed with ASD were randomly assigned to the conventional or progressive condition and received 20 sessions of intervention. Following intervention, statistical analysis was used to evaluate and compare the effects of each condition. Although both were effective in teaching the participants tact relations, there was a statistically significant difference in the number of tact relations learned in the progressive condition when compared to the conventional condition.

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. [ABSTRACT FROM AUTHOR]

Purpose of Review: The goal of this review is to challenge the dogma that urodynamics is required to identify detrusor underactivity and bladder outlet obstruction for men in urinary retention prior to offering any bladder outlet surgery in the era of holmium laser enucleation of the prostate (HoLEP). Classically, bladder outlet surgery was not recommended for patients with detrusor underactivity as men with detrusor underactivity who underwent transurethral resection of the prostate (TURP) had worse outcomes than those who underwent TURP for bladder outlet obstruction without detrusor underactivity. We review the evidence from TURP studies that led to the traditional teaching and review the latest research on the utility of urodynamics prior to HoLEP. Recent Findings: For men in urinary retention, HoLEP has more positive postoperative voiding outcomes than were noted with TURP and very high rates of spontaneous voiding even for men with urodynamics-proven detrusor underactivity or bladder acontractility. Summary: We challenge the traditional teaching that UDS is required to identify detrusor underactivity and bladder outlet obstruction prior to performing HoLEP. We argue that routine UDS prior to HoLEP is not necessary for men in urinary retention. [ABSTRACT FROM AUTHOR]

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 FROM AUTHOR]

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.

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 FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

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.

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). Fiftyfive 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 FROM AUTHOR]

Several nitrosyl tris(5,10,15-aryl)corrolate complexes of iron(III) Fe(Ar3C)(NO) with different substituents on the aryl groups are investigated to determine the effects of aryl group substituents. The high reactivity of the ferric triarylcorrolates with NO data is described in terms of the strongly electron-donating character of the Ar3C(super 3-) ligand and the quartet electronic configuration of the Fe(Ar3C) intermediate.

Introduction: Holmium laser enucleation of the prostate (HoLEP) is a size-independent treatment option for the management of benign prostatic hypertrophy. Although advancements in laser technology have led to clinical improvements in the enucleation portion of HoLEP, the morcellation aspect of HoLEP is often the rate-limiting step. We sought to compare efficiency and surgeon satisfaction in four commercial morcellators. Methods: This was an ex vivo study comparing four commercial morcellators: the Wolf Piranha™, the Lumenis VersaCut™, the JenaSurgical MultiCut Solo™, and the Hawk™ Morcellator. Four surgeons with significant experience performing HoLEPs participated. Surgeons tested each device to morcellate two different prostate models (1) morcellating as much microwave-cooked chicken breast in 10 minutes and (2) timed morcellation of bull testicles. Surgeons completed subjective surveys after each morcellator trial. Objective outcomes included the following: morcellation efficiency (g/min morcellated) and aspiration power (time to aspirate 1 L of saline). Means of continuous variables were compared using analysis of variance. Categorical variables were compared using chi-square tests. Statistical analyses were performed using SAS 9.4 (2019). Results: Comparing subjective outcomes, the Piranha™ was chosen as the safest morcellator (p = 0.0058). The least safe morcellator was thought to be the MultiCut by 75% of surgeons (p = 0.046). The Piranha™ was chosen as the most effective morcellator by 75% of surgeons (p = 0.046). Comparing objective parameters between the morcellators, the Piranha™ had the fastest aspiration time (43.50 ± 10.34 seconds, p = 0.0116). There were no significant differences in morcellation efficiency when using chicken breast (p = 0.3096). However, when comparing the morcellation efficiency using bull testicles, the Piranha™ had the highest efficiency at 39.68 ± 3.57 g/min (p = 0.0268). Conclusion: In this ex vivo study comparing four different commercially available morcellators, the Piranha™ had the highest aspiration power. No significant differences were found in morcellation efficiency using microwave-cooked chicken breast. The Piranha™ was felt to be the safest and most effective morcellator. [ABSTRACT FROM AUTHOR]

Background Antimicrobial stewardship (AS) programs are required by Centers for Medicare and Medicaid Services and should ideally have infectious diseases (ID) physician involvement; however, only 50% of ID fellowship programs have formal AS curricula. The Infectious Diseases Society of America (IDSA) formed a workgroup to develop a core AS curriculum for ID fellows. Here we study its impact. Methods ID program directors and fellows in 56 fellowship programs were surveyed regarding the content and effectiveness of their AS training before and after implementation of the IDSA curriculum. Fellows' knowledge was assessed using multiple-choice questions. Fellows completing their first year of fellowship were surveyed before curriculum implementation ("pre-curriculum") and compared to first-year fellows who complete the curriculum the following year ("post-curriculum"). Results Forty-nine (88%) program directors and 105 (67%) fellows completed the pre-curriculum surveys; 35 (64%) program directors and 79 (50%) fellows completed the post-curriculum surveys. Prior to IDSA curriculum implementation, only 51% of programs had a "formal" curriculum. After implementation, satisfaction with AS training increased among program directors (16% to 68%) and fellows (51% to 68%). Fellows' confidence increased in 7/10 AS content areas. Knowledge scores improved from a mean of 4.6 to 5.1 correct answers of 9 questions (P  = .028). The major hurdle to curriculum implementation was time, both for formal teaching and for e-learning. Conclusions Effective AS training is a critical component of ID fellowship training. The IDSA Core AS Curriculum can enhance AS training, increase fellow confidence, and improve overall satisfaction of fellows and program directors. [ABSTRACT FROM AUTHOR]

Background: Coronavirus disease 2019 (COVID-19) changed the practice of medicine in America. During the March 2020 lockdown, elective cases were canceled to conserve hospital beds/resources resulting in financial losses for health systems and delayed surgical care. Ambulatory percutaneous nephrolithotomy (aPCNL) has been shown to be safe and could be a strategy to ensure patients receive care that has been delayed, conserve hospital resources, and maximize cost-effectiveness. We aimed to compare the safety and cost-effectiveness of patients undergoing aPCNL against standard PCNL (sPCNL). Materials and Methods: Ninty-eight patients underwent PCNL at Indiana University Methodist Hospital, a tertiary referral center, by three expert surgeons from January 2020 to September 2020. The primary outcome of the study was to compare the 30-day rates of emergency department (ED) visits, readmissions, and complications between sPCNL and aPCNL. Secondary outcomes included cost analysis and stone-free rates (SFRs). Propensity score matching was performed to ensure the groups were balanced. Statistical analyses were performed using SAS 9.4 using independent t-tests for continuous variables and chi-square analyses for categorical variables. Results: Ninety-eight patients underwent PCNL during the study period (sPCNL = 75 and aPCNL = 23). After propensity score matching, 42 patients were available for comparison (sPCNL = 19 and aPCNL = 23). We found no difference in 30-day ED visits, readmissions, or complications between the two groups. aPCNL resulted in cost savings of $5327 ± 442 per case. SFRs were higher for aPCNL compared with sPCNL. Conclusions: aPCNL appears safe to perform and does not have a higher rate of ED visits or readmissions compared with sPCNL. aPCNL may also be cost-effective compared with sPCNL.

Background: Laboratory parameters and the associated clinical outcomes have been an area of focus in COVID-19 research globally. Purpose: We performed a scoping review to synthesize laboratory values described in the literature and their associations with mortality and disease severity. Methods: We identified all primary studies involving laboratory values with clinical outcomes as a primary endpoint by performing data searches in various systematic review databases until 10th August, 2020. Two reviewers independently reviewed all abstracts (13,568 articles) and full text (1126 articles) data. A total of 529 studies involving 165,020 patients from 28 different countries were included. Investigation of the number of studies and patients from a geographical perspective showed that the majority of published literature from January–March 2020 to April–June 2020 was from Asia, though there was a temporal shift in published studies to Europe and the Americas. For each laboratory value, the proportion of studies that noted a statistically significant (p < 0.05) correlation with adverse clinical outcomes (e.g., mortality, disease severity) was tabulated. Results and conclusion: Among frequently reported laboratory values, blood urea nitrogen was the most often reported predictor of mortality (91%); neutrophil-to-lymphocyte ratio was the most frequent statistically significant laboratory parameter in predicting disease severity (96%). This review highlights the temporal progression of laboratory value frequencies, as well as potentially distinct utilities of different markers for clinical outcomes of COVID-19. Future research pathways include using this collected data for focused quantitative meta-analyses of particular laboratory values correlated with clinical outcomes of mortality and disease severity.

Introduction: Although holmium laser enucleation of the prostate (HoLEP) is a highly effective surgery, there is a variable recovery period where patients may experience hematuria, dysuria, or urinary incontinence (UI). Despite preoperative consultation, there is a paucity of literature examining the effectiveness of physician-patient communication in preparing the patient for the postoperative recovery period. We sought to examine recovery expectations as a patient-reported outcome (PRO) metric for HoLEP. Methods: With institutional review board approval, we queried our electronic medical record and retrospective clinical registry to identify 50 consecutive patients that underwent HoLEP from November 2019 to March 2020 by two endourologists. Patients were provided questionnaires via Twistle© ≥6 months postoperatively. Patient demographics and perioperative course was examined in the context of responses. Our primary objective was determining whether patients felt they had a reasonable understanding of the recovery process. Results: We observed a 92% (46/50) response rate, with an average patient age of 69.4 years (range 55-88). Overall, 91.3% (42/46) felt they had a reasonable understanding of the recovery. Additionally, 97.8% (45/46) were aware of temporary UI, with 87% having ≥1 episodes of UI after catheter removal. We found 47.8% (22/46) of patients expected UI to resolve within 30 days, while 8.6% expected >90 days of UI. All patients were aware of the risk of hematuria, with 93.5% (43/46) expecting resolution within 30 days (<7 days: 47.8%; 7-14 days: 28.3%; 15-30 days: 17.4%). Conclusions: Although surgical technique continues to improve HoLEP, ensuring adequate physician-patient communication to optimize expectations is crucial. We report patient understanding of HoLEP recovery and areas for future improvement. [ABSTRACT FROM AUTHOR]

Herein, we describe a case of a patient diagnosed with prostate cancer (PCa) who presented with lower urinary tract symptoms (LUTS) and elevated Prostate Specific Antigen (PSA). He underwent Holmium Laser Enucleation of the Prostate (HoLEP) for his severe LUTS with concurrent placement of SpaceOAR gel and gold fiducials in preparation for radiation therapy (RT). After a successful operation, the patient underwent same-day discharge and catheter removal. He regained continence at 2 weeks and started RT at 9 weeks post-HoLEP. We present that concurrent placement of fiducials and SpaceOAR during HoLEP appears to be feasible, well tolerated and effective for PCa patients who elect RT. [ABSTRACT FROM AUTHOR]

Professional societies serve many functions that benefit constituents; however, few professional societies have undertaken the development and dissemination of formal, national curricula to train the future workforce while simultaneously addressing significant healthcare needs. The Infectious Diseases Society of America (IDSA) has developed 2 curricula for the specific purpose of training the next generation of clinicians to ensure the future infectious diseases (ID) workforce is optimally trained to lead antimicrobial stewardship programs and equipped to meet the challenges of multidrug resistance, patient safety, and healthcare quality improvement. A core curriculum was developed to provide a foundation in antimicrobial stewardship for all ID fellows, regardless of career path. An advanced curriculum was developed for ID fellows specifically pursuing a career in antimicrobial stewardship. Both curricula will be broadly available in the summer of 2021 through the IDSA website. [ABSTRACT FROM AUTHOR]

Background: Holmium laser enucleation of the prostate (HoLEP) is a highly effective and durable minimally invasive surgery for benign prostatic hyperplasia. Historically, alternative treatments for large glands (≥175 cc) are associated with prolonged length of stay (LOS) and postoperative catheterization. However, advances in laser technology combined with surgical technique optimization have early evidence supporting same-day discharge. We look to examine contemporary same-day discharge outcomes for large glands. Materials and Methods: With Institutional Review Board (IRB) approval we queried our electronic medical record and retrospective clinical registry to examine perioperative outcomes of large gland (≥175 cc) prostates that underwent HoLEP with consideration for same-day discharge. Results: From December 10, 2019 to September 29, 2020 we identified 55 patients with a preoperative prostate size ≥175 cc (39 CT, 12 MRI, 4 transrectal ultrasound), of which 45 were scheduled for same-day discharge and 10 for admission. Mean preoperative prostate size was 229.9 cc (range 175–535 cc) and 36 (65.5%) were in urinary retention. Mean preoperative prostate-specific antigen (PSA) was 8.58 ng/mL, American Urological Association Symptom Score (AUASS) 22.3, and Qmax 8.8 mL/second. At 3 months postoperative follow-up mean AUASS was 6.7, PSA 0.87 ng/mL and Qmax 20.4 mL/second. All comer same-day discharge rate was 70% (38/55). Of patients planned for same-day discharge 38/45 (84%) were effective. Average LOS for all patients was 11.8 hours with catheterization of 21.2 hours. When compared with 2010 published large gland outcomes, our current LOS represents a 220% reduction. Looking specifically at patients planned for same-day discharge, average LOS and catheter duration was 8.8 and 17.0 hours, whereas LOS and catheter duration for patients planned for admission was 25.7 and 39.4 hours, respectively. Conclusions: We report the first outcomes of preoperatively planned same-day discharge for HoLEP in large glands (≥175 cc). A combination of technologic advances and optimization of technique have allowed for a safe adoption of same-day discharge, providing additional advantages over alternative large gland treatments.

Background: Outcomes of holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia has been well studied. As comfort with the procedure has improved, the number of concurrent surgeries performed with HoLEP has increased. Technology and technique optimization have safely transitioned HoLEP toward same-day catheter removal and discharge. We aim to assess the success and safety of transitioning toward a same-day care pathway for patients undergoing concurrent surgeries with HoLEP. Materials and Methods: With institutional review board approvals, we queried the electronic medical record and retrospective clinical registry to examine perioperative characteristics and outcomes of patients who underwent HoLEP performed by two endourologists at two centers between July 1, 2016, and June 1, 2021, in which ≥1 concurrent surgical procedure was performed. Results: There were 188 patients with an average age of 72.3 years, who underwent HoLEP with ≥1 concurrent surgical procedure within the study period. In total, 221 non-HoLEP procedures were performed with 30/188 (16.0%) undergoing ≥3 total procedures in a single operation. The four-most common concurrent procedures were cystolitholapaxy 86/221 (38.9%), ureteroscopy 57/221 (25.8%), transurethral resection of bladder tumor 14/221 (6.3%), and percutaneous nephrolithotomy 14/221 (6.3%). Postoperatively, 3 (1.6%) patients required transfusion. After transitioning to a same-day care path, the proportion of patients who had successful same-day catheter removal and same-day discharge increased (all p < 0.05). Median length of stay decreased (from 23 hours 11 minutes to 3 hours 49 minutes, p = 0.008). Our 90-day readmission rate for urology complication was 7.9%, and only 3.6% of patients undergoing concurrent stone surgery required an additional stone surgery within 90 days. The overall Clavien–Dindo ≥3b rate was 4.8% (9-3b, 0-4, 0-5). Conclusions: Advances in HoLEP technique and technology allow for safe same-day discharge for concurrent surgery performed at the time of HoLEP. Few patients were readmitted within 90 days and no patients experienced Clavien–Dindo ≥4 complications. [ABSTRACT FROM AUTHOR]

Purpose of the Review: Although still a relatively new technology, long-term left ventricular assist devices (LVADs) for management of advanced heart failure is rapidly increasing. Initially designed as a bridge to transplant, these invasive devices are increasingly used as a destination therapy, creating unique and long-term infection risks. The aim of this comprehensive review is to highlight current evidence about the prevention, diagnosis, and management of LVAD-specific infections. Recent Findings: There are two recent, major societal guidelines (The International Society for Heart and Lung Transplantation, 2017, and the American Society of Transplantation, 2019) specifically on the diagnosis and management of infections in LVAD patients. A third guideline from the European Association for Cardio-Thoracic Surgery (2019) on general LVAD management contains a section on infection management. Recommendations tend to be concordant across the guidelines without major disagreements and suggest that for superficial infections, limited-course durations of antimicrobials are acceptable. For infections of deeper portions of the device, long-term antimicrobial regimens, often with chronic suppressive strategies remain the mainstay of treatment; however, this recommendation is based primarily on expert opinion as high-quality evidence to support best practices remains limited. The role of surgical management remains unknown. Summary: Management of long-term, device-related infections in patients with advanced heart failure is challenging and should include input from a multi-disciplinary team of providers to determine the best management strategy. A strong emphasis on best prevention practices is a necessity. With this relatively new technology, evidence-based data to guide best practices remains limited and is an important area of future research. [ABSTRACT FROM AUTHOR]

We present a patient with acute myeloid leukemia and prolonged, severe neutropenia who developed fulminant Clostridioides difficile infection refractory to medical therapy and was high‐risk for surgical intervention. He was treated with fecal microbiota transplantation (FMT) for life‐saving cure. The patient had subsequent clinical improvement, however, developed multidrug‐resistant Pseudomonas aeruginosa bacteremia 2 days post‐procedure. We describe subsequent investigation of this event that found this bacteremia was not related to the donor stool administered during FMT. This case adds to the literature that FMT could be considered in heavily immunocompromised patients with fulminant Clostridioides difficile infection where maximal medical therapy has been ineffective and surgery may carry an excessively high mortality risk.

An otherwise healthy 7-year-old boy was diagnosed with malignant large cell calcifying Sertoli cell tumor (LCCSCT) of the testis. He underwent attempted partial orchiectomy with conversion to radical orchiectomy due to suspected malignancy on intraoperative frozen section. There was no lymph node or visceral metastases. To our knowledge, this is the first report of malignant LCCSCT in the prepubertal population. LCCSCT of the testis is an extremely rare neoplasm, with low malignant potential. Malignant cases are exclusively reported previously in the adult population. We report the first case of malignant LCCSCT in a pediatric patient. We review the literatures and discuss the clinical, pathologic features and treatments of malignant LCCSCT. [ABSTRACT FROM AUTHOR]

HIV-1 envelope (Env) mimetics are candidate components of prophylactic vaccines and potential therapeutics. Here we use a synthetic V3-glycopeptide (“Man9-V3”) for structural studies of an HIV Env third variable loop (V3)-glycan directed, broadly neutralizing antibody (bnAb) lineage (“DH270”), to visualize the epitope on Env and to study how affinity maturation of the lineage proceeded. Unlike many previous V3 mimetics, Man9-V3 encompasses two key features of the V3 region recognized by V3-glycan bnAbs—the conserved GDIR motif and the N332 glycan. In our structure of an antibody fragment of a lineage member, DH270.6, in complex with the V3 glycopeptide, the conformation of the antibody-bound glycopeptide conforms closely to that of the corresponding segment in an intact HIV-1 Env trimer. An additional structure identifies roles for two critical mutations in the development of breadth. The results suggest a strategy for use of a V3 glycopeptide as a vaccine immunogen.
