Specialty-Specific Trends in Surgery for Apical Pelvic Organ Prolapse Post Vaginal Mesh.

IMPORTANCE: Since transvaginal mesh (VM) kits for apical pelvic organ prolapse (APOP) were labeled "high-risk" in 2016 and subsequently banned in 2019 by the U.S. Food and Drug Administration, the most common remaining surgical options include abdominal mesh-augmented sacrocolpopexy (AS) and transvaginal native tissue suspension (VN). OBJECTIVE: The objective of this study was to determine temporal trends in APOP procedures for urologists and gynecologists. STUDY DESIGN: Between 2011 and 2020, the American College of Surgeons National Surgical Quality Improvement Program database was queried for AS, VM, and VN. RESULTS: There were 26,477 cases of APOP repair (32% AS, 6% VM, 62% VN) included, 9% by urologists. Urologists operated on older (65 vs 61 years) patients with more medical comorbidities. Urologists performed significantly higher proportion of AS (65% vs 29%) and VM (8% vs 6%) relative to VN (27% vs 65%) than gynecologists ( P < 0.0001). Transvaginal mesh utilization has decreased over time for both specialties ( P < 0.05); nonsignificant trends toward increasing AS ( P = 0.1646) in urologists and VN ( P = 0.0913) in gynecologists concurrently occurred. Significant independent predictors of the operating surgeon being a urologist were surgery being performed in the latter half of the cohort (2016-2020; odds ratio [OR], 1.22), non-White patient race (OR < 1 for all), a concomitant sling being placed (OR = 0.89), the surgery being VM (OR = 2.95) or AS (OR = 4.36), the patient being older (OR > 1 for each age range), and having a higher frailty index score (OR = 1.16). CONCLUSIONS: Significant differences in APOP repair choices exist between specialties. Urologists operate on older, more medically complex patients while demonstrating a strong preference for mesh-augmented compared with transvaginal native tissue repairs.

Impact of pre- and peri-operative risk factors on length of stay and hospital readmission following minimally-invasive partial nephrectomy.

Objective: We conducted an analysis of the American College of Surgeons National Surgical Quality Improvement Program database for minimally-invasive partial nephrectomy cases reported with the goal to identify pre- and peri-operative variables associated with length of stay (LOS) greater than 3 days and readmission within 30 days. Methods: Records from 2008 to 2018 for "laparoscopy, surgical; partial nephrectomy" for prolonged LOS and readmission cohorts were compiled. Univariate analysis with Chi-square, t-tests, and multivariable logistic regression analysis with odds ratios (ORs), p-values, and 95% confidence intervals assessed statistical associations. Results: Totally, 20 306 records for LOS greater than 3 days and 15 854 for readmission within 30 days were available. Univariate and multivariable analysis exhibited similar results. For LOS greater than 3 days, undergoing non-elective surgery (OR=5.247), transfusion of greater than four units within 72 h prior to surgery (OR=5.072), pre-operative renal failure or dialysis (OR=2.941), and poor pre-operative functional status (OR=2.540) exhibited the strongest statistically significant associations. For hospital readmission within 30 days, loss in body weight greater than 10% in 6 months prior to surgery (OR=2.227) and bleeding disorders (OR=2.081) exhibited strongest statistically significant associations. Conclusion: Multiple pre- and peri-operative risk factors are independently associated with prolonged LOS and hospital readmission within 30 days of surgery using the American College of Surgeons National Surgical Quality Improvement Program data. Recognizing the risks factors that can potentially be improved prior to minimally-invasive partial nephrectomy is crucial to informing patient selection, optimization strategies, and patient education.

The impact of verbal goal setting on operating room turnover time: a randomized trial.

INTRODUCTION AND HYPOTHESIS: Operating room turnover times are highly variable, with longer times having a significant negative impact on hospital costs, surgeon volume, and satisfaction. The primary aim of this randomized trial was to examine the impact of a verbalized time goal on the likelihood of meeting institutional goals. METHODS: This is a prospective, single-blind, randomized study conducted across four operative sites: inpatient main campus and three outpatient centers. Sequential cases for the same surgeon in the same room were randomized to receive a verbal prompt versus usual care, in which no goal setting was verbalized. Multivariate and univariate statistical analyses were performed. RESULTS: From July through October 2022, five attending surgeons randomized 88 cases (44 verbal prompt, 44 usual care). Of these, 30 were at the main inpatient hospital. The case mixture included 36% vaginal, 27% endoscopy, 8% open, 10% robotic, and others. Average turnover time was 51.7 and 35.3 min for inpatient and outpatient cases respectively. Overall, only 39.8% of cases hit the institutional turnover time goal. Verbal prompting did not significantly increase the likelihood of achieving the institutional goal (38.4% vs 43.4% p = 0.352) except for in minor surgery (64.0 vs 39.0%, p = 0.0477). A verbal prompt reduced turnover time in major surgery (59.7 vs 47.8 min, p = 0.0445). CONCLUSION: Our academic center achieved goal turnover times in only 39.8% of cases. Although verbal prompting did not significantly improve the likelihood of meeting institutional goals in the group as a whole, some subgroups were significantly improved.

Persistent need for ongoing medical or surgical therapy despite UroLift: Data from an academic center.

INTRODUCTION: The prostatic urethral lift (PUL) is a popular surgical option for benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). Prior 5-year data from the multicenter L.I.F.T. trial suggested durability and a surgical retreatment rate of 13.6% at five years. We assessed the proportion of patients who had ongoing medical or surgical BPH management following PUL. METHODS: With institutional review board approval, cases of PUL performed from 2015-2020 at our academic institution were retrospectively reviewed for management of BPH following PUL. RESULTS: A total of 209 men were identified, with followup available for 198 (95%). Mean age was 68.9 years and mean followup was 18.5 months. Mean prostate size was 43 g. Patients were discharged from recovery in 97% of cases, with 29% discharged with indwelling or intermittent catheterization. The rate of 30-day complications was 18%, with 89% graded Clavien I-II. Postoperatively, mean improvements in International Prostate Symptom Score (IPSS) and quality of life subscore (QoL) were 5.3 and 1.1 points, respectively. Unplanned emergency room or clinic visits within 30 days of the procedure occurred in 14% and 17% of men, respectively, with 4% requiring hospital readmission. In followup, α-blockers and/or 5α-reductase inhibitors were continued or initiated postoperatively for 44% of men; 20% of men required repeat surgical intervention at a mean of 19.2 months (1.4-56.4), consisting of repeat PUL (30%), transurethral resection of prostate (28%), or thulium laser enucleation (18%). Overall, 53% of men needed medication and/or repeat surgery for BPH following PUL, and this was independent of age, race, prostate volume, intravesical prostate protrusion, baseline IPSS and QOL, stricture, number of implants used, or a history of urinary retention (p>0.05). CONCLUSIONS: Most men undergoing PUL require ongoing medical and/or surgical management for BPH. Patients should be counseled as to the likelihood of failure as a unimodal therapy long-term.

Anterior approach sacrospinous hysteropexy: native tissue compared with mesh-augmented repair for primary uterovaginal prolapse management.

INTRODUCTION AND HYPOTHESIS: Anterior sacrospinous hysteropexy (SSH) was popularized by transvaginal mesh kits. Following mesh-kit market withdrawal, we hypothesized similar efficacy through native-tissue reattachment of the pubocervical fascia with fixation of the anterior cervix to the sacrospinous ligament. Few analyses for anterior native-tissue versus mesh-augmented SSH exist. METHODS: A retrospective analysis of women who underwent transvaginal anterior SSH between 01 January 2016 and 31 December 2022 was performed. Women who underwent a mesh-augmented (Uphold Lite Vaginal Support System™) versus native-tissue repair were compared. Composite success was defined as no bulge symptoms, no retreatment, and no recurrence beyond the hymen with apex nondescended > one third of the total vaginal length. Descriptive and bivariate statistics were obtained as indicated. RESULTS: Of 223 women screened, inclusion criteria were met by 124 (40 mesh-augmented; 84 native-tissue). There was no difference in pre-operative characteristics between groups. Composite success was demonstrated in 95.2% of women with a median follow-up of 224 days (range: 30-988). Two women in the mesh-augmented group reported bulge symptoms and underwent re-treatment with a pessary. Four women in the native-tissue group reported bulge symptoms; 3 underwent re-treatment (2 pessary, 1 surgery). There were no differences in composite success rates between groups (p=0.954). There were additionally no differences in intra-operative (p=0.752) or post-operative (p=0.292) complication rates between the groups. There were no mesh-related complications, including exposure or chronic pelvic pain. CONCLUSIONS: Ninety-five percent of women achieved surgical success and the use of mesh augmentation did not confer added benefit in terms of efficacy or complications when compared with native tissue. Further long-term data are needed to continue our assessment of native-tissue anterior SSH.

Outcomes and Costs Following Mini-percutaneous Nephrolithotomy or Flexible Ureteroscopic Lithotripsy for 1-2-cm Renal Stones: Data From a Prospective, Randomized Clinical Trial.

PURPOSE: We evaluate the outcomes of ureteroscopy vs prone mini-percutaneous nephrolithotomy for 1-2-cm renal stones using a 2-group parallel randomized control trial. MATERIALS AND METHODS: Adult patients presenting with renal stones between 1 and 2 cm were randomized. Exclusion criteria included solitary kidney, multiple stones, and comorbidities precluding prone positioning. Block randomization was performed and was opened to the surgeon the morning of the procedure. Stone-free rate was evaluated by computed tomography 1-30 days postoperatively. Complications, re-treatment rates, and costs were evaluated. RESULTS: A total of 51 mini-percutaneous nephrolithotomy and 50 ureteroscopy patients were included. Baseline demographics were similar. Using a 2-mm cutoff, stone-free rate was higher in the mini-percutaneous nephrolithotomy group (76 vs 46%, P = .0023). The residual stone burden was significantly higher in the ureteroscopy group than the mini-percutaneous nephrolithotomy group (3.6 vs 1.4 mm, P = .0026). Fluoroscopy time was significantly higher in the mini-percutaneous nephrolithotomy group (273 vs 49 seconds, P < .0001). There were no differences in postoperative complications within 30 days, the necessity of a secondary procedure within 30 days, and pre- to postoperative creatinine change (P > .05). Surgical time did not vary significantly (P = .1788). Average length of stay was higher in the mini-percutaneous nephrolithotomy group (P < .0001). Both net revenue and direct costs were higher in mini-percutaneous nephrolithotomy procedures (P < .05), though they offset each other with a nonsignificant operating margin (P = .2541). CONCLUSIONS: In a prospective, randomized, controlled clinical trial using a 2-mm residual stone burden cutoff, mini-percutaneous nephrolithotomy was more likely to render patients stone-free than flexible ureteroscopy. Complications, surgical times, and operating margins did not vary between the approaches.

Investigating the Impact of Kratom (Mitragyna speciosa) Use Upon Male Sexual Health.

Purpose: Kratom (Mitragyna speciosa) exhibits µ-receptor agonism and is used as an opioid substitute. While opioids are known to inhibit sexual behavior, less is known regarding kratom. We conducted a pilot study to assess the subjective impact of kratom upon male sexual health including erectile and ejaculatory function. Patients and Methods: Twitter and Reddit (r/Kratom) were accessed to disseminate our survey featuring validated instruments (the International Index of Erectile Function, IIEF, and the premature ejaculation diagnostic tool, PEDT). Sexual health prior to and after 4 weeks of kratom use was assessed. Results: Most males surveyed (n = 165) were 18-40 years old (84.9%), with 95.8% of respondents using it at least weekly and 82.4% using kratom for ≥1 year. Reasons for use included treating pain (39.4%), and mental health conditions (63.6%). Kratom was associated with a positive (37.7%) and negative (20.5%) impact on sexual health. Kratom subjectively increased time to ejaculation in 104 (66.6%) patients, perceived as positive by 62 (59.6%). Seventy-eight patients answered questions about premature ejaculation. The median (with interquartile range, IQR, following;) pre-kratom and kratom use scores were 13.0; 8.0 and 6.5; 5.0, respectively (p < 0.001). Ejaculation before 5 minutes improved after kratom (51.3% vs 12.8%) (p < 0.0001). Following kratom use, patients reported lack of frustration with ejaculation prior to desire (21.8% vs 61.5%) (p < 0.001). The erectile function domain of the IIEF was statistically significantly different however - clinically similar pre-kratom use (29.0; 5.75) versus 27.0; 6.75 during kratom use (p = 0.037). Conclusion: Clinicians treating male sexual health should be aware of kratom and its potential effect on ejaculatory and erectile function.

Differences in Surgical Practice Patterns of Vaginal Native Tissue Repair for Pelvic Organ Prolapse Between Urologists and Gynecologists.

IMPORTANCE: Surgeon specialty training may influence the combination of transvaginal procedures for pelvic organ prolapse (POP) repair. Isolated transvaginal anterior compartment repair (AR) without concurrent apical suspension (ApS) is a known risk factor for POP recurrence. OBJECTIVES: Our primary aim was to compare the prevalence of isolated AR between urologists versus gynecologists. Our secondary aim was to compare associated postoperative complications. STUDY DESIGN: We queried the American College of Surgeons National Surgical Quality Improvement Program for vaginal POP repair procedures (Current Procedural Terminology codes 57240, 57260, 57265, 57268, 57282, 57283) over a 5-year period by designated surgical specialty. We analyzed the relationships between specialty, vaginal repair type, operative details, and 30-day postoperative complications. RESULTS: Between January 2015 and December 2019, we included 16,093 women who underwent transvaginal POP repair, 90% performed by gynecologists and 10% by urologists. Urologists were more likely to perform an isolated AR without concurrent ApS (56% vs 47%, P < 0.0001). Gynecologists performed more isolated ApS (11% vs 9%) and combined AR with ApS (43% vs 35%, P < 0.0001). Overall, concurrent urethral sling placement was performed in 27% of cases, regardless of POP repair type, with no difference between specialties (P > 0.05). There were no differences in 30-day reoperations, readmissions, surgical site infections, urinary tract infections, or hospital stay lengths between specialties (P > 0.05). CONCLUSIONS: Urologists perform a minority of vaginal POP repairs and were more likely to perform isolated AR than gynecologists. The absence of concurrent ApS may increase the likelihood of prolapse recurrence. Immediate complication rates for each procedure did not differ.

Haploid Parthenogenetic Embryos Exhibit Unique Stress Response to pH, Osmotic and Oxidative Stress.

Preimplantation-stage embryos are susceptible to various types of stress when cultured in vitro. Parthenogenetic embryos that lack spermatozoa contribution exhibit aberrant developmental dynamics due to their uniparental origin. Herein, we assessed whether the absence of paternal genome affects the susceptibility of the embryos to pH, osmotic and oxidative stress. Haploid parthenogenetic embryos (HPE) (activated oocytes with 1 pronucleus and 2 polar bodies) were generated by incubating cumulus oocyte complexes of Swiss albino mice with 10 mM strontium chloride for 3 h. Normally fertilized embryos (NFE) (fertilized oocytes with 2 pronuclei and 2 polar bodies) were derived using in vitro fertilization. At 2-cell stage, both HPE and NFE were exposed to various stressors including pH (6.8 to 8.2), osmotic (isotonic, hypotonic, and hypertonic), and peroxidatic oxidative (H2O2, 25 µM) stress. Endoplasmic reticulum stress response, mitochondrial membrane potential, and the rate of blastocyst development were assessed. HPE were susceptible to alteration in the pH that was well tolerated by NFE. Similarly, HPE displayed remarkable difference in sensitivity to hypertonic stress and oxidative stress compared to NFE. The results clearly indicate that the oocytes that develop into embryos in the absence of paternal contribution are more vulnerable to environmental stressors, further highlighting the importance of spermatozoa contribution and/or the ploidy status in mitigating these stressors and towards healthy early embryo development.

Comparative outcomes and cost of ambulatory PCNL in select kidney stone patients.

Limited hospital resources and access to care during the COVID-19 pandemic led us to implement a quality-improvement study investigating the feasibility, safety, and costs of same-day discharge after PCNL. The outcomes of 53 consecutive first-look PCNL patients included in a same-day discharge protocol during COVID-19 were compared to 54 first-look PCNL patients admitted for overnight observation. Control group had a similar comorbidity profile. Demographics, operative details, 30 day outcomes and readmissions, complications, and cost were compared between the two groups. Same-day discharge and one-day admission post-PCNL patients did not have significantly different baseline characteristics. The study group were more likely to have mini-PCNL (81% vs 50%, p < 0.01). Operative characteristics including median pre-operative stone burden (1.4 vs 1.7 cm3, p = 0.47) and post-operative stone burden (0.14 vs 0.18 cm3, p = 0.061) were similar between the two groups. Clavien-Dindo complication rates were lower in the study group compared to controls (0 vs 7%, p = 0.045). Readmission rates (2 vs 4%, p = 0.569) and ED visits (4 vs 6%, p = 0.662) were similar between the two groups. Total cost ($6,648.92 vs $9,466.07, p < 0.01) was significantly lower and operating margin ($4,475.96 vs $1,742.16, p < 0.01) was significantly higher for the same-day discharge group. Percutaneous nephrolithotomy may be performed in select patients without an increase in short-term complications, ED visits, or readmissions. Patients undergoing mini-PCNL are particularly amenable to same-day discharge, however, standard PCNL patients should not be excluded from consideration. Avoiding overnight admission decreases total cost and increased hospital operating margin.

Anti-tuberculosis drugs used in a directly observed treatment short course (DOTS) schedule alter endocrine patterns and reduce the ovarian reserve and oocyte quality in the mouse.

CONTEXT: Tuberculosis is one of the major infectious diseases, with people of reproductive age group having a high risk of infection. AIMS: The present study was designed to understand the consequences of anti-tuberculosis drugs (ATDs) used in DOTS (directly observed treatment short course) schedule on ovarian function. METHODS: Adult female Swiss albino mice were orally administered with combinations of ATDs used in the DOTS schedule every day for 4weeks. At 2weeks after the cessation of ATDs administration, the endocrine changes and ovarian function were assessed in mice. KEY RESULTS: Administration of ATDs to mice resulted in a prolonged estrous cycle, reduced ovarian follicle reserve, alteration in FSH, LH, and progesterone level, and decreased the number of ovulated oocytes. Further, the degree of fragmentation, degeneration, abnormal distribution of cytoplasmic organelles, abnormal spindle organisation, and chromosomal misalignment were higher in oocytes that were ovulated following superovulation. Blastocysts derived from ATDs treated mice had significantly lower total cell numbers and greater DNA damage. A marginal increase in the number of resorbed fetuses was observed in all the ATDs treated groups except in the multidrug resistance treatment group. Male progeny of ATDs treated mice had decreased sperm count and lower progressive motility, while female progeny exhibited a non-significant reduction in the number of oocytes ovulated. CONCLUSIONS: Theresults of this study suggest that ATDs can have significant adverse effects on the ovarian reserve, cytoplasmic organisation of oocytes, and can potentially cause transgenerational changes. IMPLICATIONS: The findings of the present study indicate ovarian toxicity of ATDs and warrant further research in the direction of identifying alternate drugs with minimal toxicity, and strategies to mitigate the ovarian toxicity induced by these drugs.

Safety and Efficacy of Phenylephrine Administration for the Treatment of Ischemic Priapism: An Opportunity for Quality Improvement in Periprocedural Safety Assessment.

OBJECTIVE: To determine the safety and efficacy of hourly, high dose phenylephrine (>1000 µg) for acute ischemic priapism (AIP) through monitoring adverse hemodynamic events amongst risk profiles. METHODS: An IRB-approved retrospective review of patients with AIP from 2010 to 2020. Patients were stratified to a low or high dose phenylephrine group based on cumulative, hourly dose of ≤1000 µg and > 1000 µg respectively and examined for successful resolution of their AIP. The safety profile of phenylephrine for patients at risk for adverse hemodynamic events was examined. RESULTS: A total of 123 patients were identified with a median age of 40 (range: 7-76) years with median time from AIP onset to presentation of 11 (2-168) hours. A total of 97 men received phenylephrine (78.9%) and detumescence was achieved nonoperatively in 62 of these men (63.9%) with a mean priapism duration of 8.7 hours. Those resolving with phenylephrine administration had a mean duration of 8.8 ± 5.6 vs 57.3 ± 37.1 hours without resolution P < .001. Among low and high dose phenylephrine groups (500 and 2000 µg respectively), the median duration of AIP was 10 and 12 hours respectively without a difference in AIP resolution (P > .05). Twenty-one patients (17.1%) were deemed at risk for phenylephrine complication of which 4 (4.1%) had phenylephrine discontinued due to hemodynamic changes. CONCLUSION: Nonoperative resolution of AIP with phenylephrine does not appear to be dose-dependent and hemodynamic changes secondary to phenylephrine administration may be underreported. Future work should utilize standardized risk assessment and periprocedural monitoring for hemodynamic change.

Evaluation of a Novel Multimodal Opioid-Free Postoperative Pain Management Pathway Following Robotic-Assisted Radical Prostatectomy: A Pilot Series in the Veteran Population.

BACKGROUND: Veterans have disproportionate risk of opioid misuse and abuse compared to the civilian population. Managing acute postoperative pain without opioids is of the utmost importance for the Veteran patient population. This pilot study evaluates a novel multimodal opioid-free pain control regimen by assessing postoperative pain in Veterans undergoing robotic-assisted radical prostatectomy (RARP). METHODS: Prospective data was collected from patients undergoing RARP at a Department of Veterans Affairs Medical Center. Patients in the opioid-cohort received tramadol, hydrocodone-acetaminophen, or oxycodone-acetaminophen postoperatively. The opioid-free novel multimodal approach consisted of 100 mg gabapentin TID, 15 mg ketorolac Q6 hours, and 1 mg scheduled IV acetaminophen Q6 hours. Pain scores were collected using a visual analogue pain scale on postoperative days 0 and 1. RESULTS: Data was collected from 57 patients, 33 treated with opioids and 24 with the opioid-free pathway. There were no significant differences in demographics (P > .05) between cohorts. No significant differences were observed for preoperative and intraoperative variables (P > .05). Average postoperative day 0 pain scores for opioid-free (2.2 ± 3.1) and opioid treatments (3.1 ± 3.1) were not statistically different (P = .1321). Postoperative day 1 differences of average pain scores for opioid-free (0.9 ± 1.9) and opioid (1.6 ± 3.1) treatments were not statistically significant (P = .1647). CONCLUSIONS: The novel multimodal opioid-free treatment in this study may be effectively utilized for postoperative pain during hospital recovery of Veterans undergoing RARP. Future directions include a randomized control clinical trial in the general population.

Patient Satisfaction, Provider Productivity, and Efficacy of a Standardized Preparatory Toolkit With Broad Telemedicine Adaptation in an Outpatient Urology Clinic.

IMPORTANCE: The COVID-19 pandemic prompted telemedicine adoption. In March 2020, we developed an implementation toolkit with a nursing protocol for patient preparation before tertiary care urology clinic visits. OBJECTIVES: Our primary objective was to determine patient satisfaction after implementation of a telemedicine toolkit. Our secondary objective was to assess downstream productivity generated from telehealth visits. STUDY DESIGN: We prospectively conducted a postvisit survey that included the Telehealth Usability Questionnaire, a validated survey assessing patient satisfaction, for all patients with documented completion of the nursing protocol to assess patient experience and satisfaction. We then performed a retrospective chart review of all telemedicine visits to determine downstream outcomes, including imaging and procedure scheduling. RESULTS: Between April and May 2020, 1,422 visits were completed, of which 265 had complete nursing protocol documentation. Eighteen of 265 (6.8%) reported setup assistance. Four (1.8%) were unsuccessful and converted to a nonvisual phone visit. Overall, 186 (70.1%) completed the Telehealth Usability Questionnaire with a mean score of 118.31 ± 23.44. High satisfaction was reported regardless of race, marital status, income, education, employment status, or travel distance. Younger age ( P = 0.017) and female sex ( P = 0.017) were associated with greater satisfaction. Of 1,422 total visits, imaging was ordered in 29%, office procedures scheduled in 14%, and surgery scheduled in 14%. New visits were more likely to result in procedure and surgery scheduling than returns ( P < 0.0001). CONCLUSIONS: Our telemedicine toolkit designed to maximize patient engagement was successful in achieving patient-provider connectivity in 98% of patients with high satisfaction. Telemedicine visits are effective to provide comprehensive urologic care with implications beyond the pandemic.

Safety and economics of an enhanced recovery after surgery protocol in pelvic reconstructive surgery.

INTRODUCTION AND HYPOTHESIS: We hypothesized that an enhanced recovery after surgery (ERAS) protocol for patients undergoing female pelvic reconstructive surgery would conserve hospital resources without compromising patient safety. METHODS: In June 2020, an ERAS protocol designed to promote same-day discharge was initiated that included pre-operative hydration, a urinary anesthetic, non-narcotic analgesia, perineal ice, a bowel regimen, enrollment of the family to assist with care, and communication regarding planned same-day discharge. We compared demographic, operative, hospital stay, complications, and cost data in patients undergoing pelvic organ prolapse or incontinence surgery over 4 sequential months pre (PRE; N = 82) and post (POST; N = 91) ERAS implementation using univariate statistics. RESULTS: There were no differences in demographics, operative details, or complications (p > 0.05). There were no significant differences in overall revenues or expenses (p > 0.05), but bed unit cost was significantly lower in the POST group ($210 vs $533, p < 0.0001). There was a trend toward an increased operating margin in POST patients ($4,554 vs $2,151, p = 0.1163). Significantly more POST surgeries were performed in an ambulatory setting (73.6% vs 48.8%, p = 0.0008) and resulted in same-day discharge (80.2% vs 50.0%, p = 0.0003). There were no differences in the rates of emergency room or unexpected clinic visits (p > 0.05). Prescribed post-operative opiate dose was significantly reduced in POST patients (p < 0.0001). CONCLUSIONS: In patients undergoing female pelvic reconstructive surgery, an ERAS protocol facilitated transfer of procedures to an ambulatory surgical site and permitted same-day discharge without increasing complications, clinic visits, or emergency room visits. It also reduced bed unit cost and may improve operating margins.

Application of MXenes for water treatment and energy-efficient desalination: A review.

MXenes are a new type of two-dimensional (2D) material which are rapidly gaining traction for a range of environmental, chemical and medical applications. MXenes and MXene-composites exhibit high surface area, superlative chemical stability, thermal conductivity, hydrophilicity and are environmentally compatible. Consequently, MXenes have been successfully employed for hydrogen storage, semiconductor manufacture and lithium ion batteries. In recent years, MXenes have been utilized in numerous environmental applications for treating contaminated surface waters, ground and industrial/ municipal wastewaters and for desalination, often outperforming conventional materials in each field. MXene-composites can adsorb multiple organic and inorganic contaminants, and undergo Faradaic capacitive deionization (CDI) when utilized for electrochemical applications. This approach allows for a significant decrease in the energy demand by overcoming the concentration polarization limitation of conventional CDI electrodes, offering a solution for low-energy desalination of brackish waters. This article presents a state-of-the-art review on water treatment and desalination applications of MXenes and MXene-composites. An investigation into the kinetics and isotherms is presented, as well as the impact of water constituents and operating conditions are also discussed. The applications of MXenes for CDI, pervaporation desalination and solar thermal desalination are also examined based on the reviewed literature. The effects of the water composition and operational protocols on the regeneration efficacy and long-term usage are also highlighted.

A New Gold Rush: A Review of Current and Developing Diagnostic Tools for Urinary Tract Infections.

Urinary tract infections (UTIs) are one of the most common infections in the United States and consequently are responsible for significant healthcare expenditure. The standard urine culture is the current gold standard for diagnosing urinary tract infections, however there are limitations of the test that directly contribute to increased healthcare costs. As a result, new and innovative techniques have been developed to address the inefficiencies of the current standard-it remains to be seen whether these tests should be performed adjunctly to, or perhaps even replace the urine culture. This review aims to analyze the advantages and disadvantages of the newer and emerging diagnostic techniques such as PCR, expanded quantitative urine culture (EQUC), and next generation sequencing (NGS).

PFAS removal by ion exchange resins: A review.

Per- and poly-fluoroalkyl substances (PFAS) represent a large family of anthropogenic organic compounds with a wide range of industrial and commercial applications. PFAS have become a global concern due to their toxicity and bio-accumulative properties. PFAS species have been ubiquitously detected in natural waters, wastewaters, sludge, and aquatic and terrestrial species which are anionic, zwitterionic and neutral. The ion exchange (IX) process for PFAS removal is an efficient technology for the remediation of PFAS-laden surface, ground and effluent wastewaters. This approach is more effective towards eliminating emerging short-chain PFAS which are not removed by carbon-based adsorption processes. This article presents a state-of-the-art review of PFAS removal from water via IX process. The evaluation and comparison of various IX resins in terms of kinetics and isotherms is presented. Literature data indicates that IX isotherm uptake capacity for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) can range up to 5 mmol/g on commercially available IX resins such as IRA 958 and IRA 67. The mechanism involved in the PFAS uptake process, such as diffusion, electrostatic interactions and hydrophobic effects are discussed. The effects of the eluent variability on the regeneration efficacy are also highlighted and the effect of single-use vs reuse for newly developed PFAS-specific IX resins are also examined based on the reviewed literature.

Short-term outcomes of sacrospinous hysteropexy through an anterior approach.

INTRODUCTION AND HYPOTHESIS: The posterior approach to sacrospinous hysteropexy has been well studied but little is known about the anterior approach. This study assessed the efficacy and complications of an anterior approach to sacrospinous hysteropexy compared to hysterectomy with apical repair. We hypothesized that anterior sacrospinous hysteropexy has similar efficacy and fewer complications. METHODS: This retrospective cohort study compared patients who underwent native-tissue anterior sacrospinous hysteropexy (cases) with those who underwent hysterectomy with apical repair (controls). Composite success was defined as (1) leading edge of prolapse not beyond the hymen and apex not descended > 1/3 total vaginal length; (2) no vaginal bulge symptoms; (3) no prolapse retreatment. Descriptive and bivariate statistics were performed as well as a Cox regression analysis for time to failure. RESULTS: Fifty cases and 97 controls were compared. The median follow-up time was 7.6 months. Operative time was shorter in the hysteropexy group (110.7 vs. 155.9 min, p < 0.001). The composite success was 92% for both cases and controls (p = 1.000) with no difference in time to surgical failure (p = 0.183). There were no serious intraoperative complications in the hysteropexy group and six in the control group (3 transfusions, 1 conversion to laparotomy, 1 ureteral injury, 1 cystotomy; p = 0.101). There was no difference in the number of postoperative complications (22.0% vs. 30.9%, p = 0.203). CONCLUSIONS: For primary uterine prolapse, anterior sacrospinous hysteropexy has similar short-term efficacy compared to hysterectomy with apical repair with shorter operative time and a trend towards fewer serious complications.
