However, the efficacy is not well reported. Therefore, the objective of the study was to conduct a systematic review and meta-analysis of the available evidence on prevention of uncomplicated wound infections by prophylactic topical antibiotics. Materials and methods: The search included Pubmed, Google Scholar, SCOPUS, Embase, Cochrane, ClinicalTrials.gov, International Clinical Trials Registry Platform, National Technical Information Service, and the National Guidelines Clearinghouse. Results: We identified eight randomized controlled trials and four quasi-randomized trials that met the criteria for the systematic review. Of these trials, 11 studies were pooled for meta-analysis to compare the effects of topical antibiotics versus placebo and 4 studies were pooled for comparison of effects of topical antibiotics versus topical antiseptics on uncomplicated wounds. Fewer wound infections occurred in the topical antibiotic arms compared to placebo (pooled risk ratio: 0.57 [95% CI: 0.37 to 0.86]; p=0.01 and pooled risk difference: −3.1% [95% CI: −5.8% to −0.34%]; p=0.03). Compared to antiseptics, topical antibiotics demonstrated statistically significant relative risk reduction (pooled risk ratio: 0.56 [95% CI: 0.23 to 0.91]; p=0.02), while there was no significant absolute risk reduction (pooled risk difference: −3.7% [95% CI: −7.9% to +0.6%]; p=0.09). Conclusion: Topical antibiotics are effective in reducing wound infections after surgical procedures, but the absolute benefit is small. Given the global emergence of antimicrobial resistance, judicious use of antibiotics is encouraged and use of antiseptics should be considered as a reasonable alternative to topical antibiotics.

Objectives. West Nile virus (WNV) continues to cause seasonal epidemics of neuroinvasive disease and febrile illness, which have been most dramatic in the central plains states. We studied the epidemiology of WNV disease in North Dakota (ND), a highly epidemic state, six years following its first appearance in the state. Methods. We analyzed information from cases of WNV disease reported to the ND Department of Health during August 2002 through December 2007. Results. A total of 1,246 cases of WNV disease were reported in ND; 183 cases experienced neuroinvasive disease, including meningitis, encephalitis, or acute flaccid paralysis. Risk factors associated with developing neuroinvasive disease rather than West Nile fever included older age, male gender, and residence in a rural area. Annual cumulative incidence of neuroinvasive disease in ND ranged from 0.3 per 100,000 population to 14.6 per 100,000 population. Conclusions. Annual cumulative incidence rates of West Nile neuroinvasive disease suggest that this region offers favorable conditions for its continued enzootic transmission, which highlights the need for improved targeted prevention measures, particularly for rural areas of the state.

Background: The transradial approach for percutaneous coronary procedures has the advantage of reduced access site complications but is associated with specific technical challenges in comparison with the transfemoral approach. Transradial procedure failures can sometimes be due to variation in radial artery anatomy. However, data describing such variations are limited. Objective: To evaluate the incidence and impact of radial artery anomalies in patients undergoing transradial coronary procedures. Methods: Retrograde radial arteriography was performed in all patients presenting for a first-time radial procedure. Patient characteristics, radial artery anatomy and procedural outcome were assessed. Results: 1540 consecutive patients were studied, 70.6% male, mean (SD) age 63.6 (11.1) years. The overall incidence of radial artery anomaly was 13.8% (n = 212). 108 (7.0%) patients had a high-bifurcating radial origin, 35 (2.3%) had a full radial loop, 30 (2.0%) had extreme radial artery tortuosity and 39 (2.5%) had miscellaneous anomalies such as radial atherosclerosis and accessory branches. Overall transradial procedural success was 96.8%. Procedural failure was more common in patients with anomalous anatomy than in patients with normal anatomy (14.2% vs 0.9%, p<0.001). Procedural failure in patients with high radial bifurcation, radial loop, severe radial tortuosity and other anomalies was 4.6%, 37.1%, 23.3% and 12.9%, respectively. 15 (1%) vascular complications occurred, all of which were treated conservatively without ischaemic sequelae. Conclusion: Anomalous radial artery anatomy is relatively common and is a significant cause of procedural failure. Within each specific anomalous pattern there is a differential procedural failure rate. This has implications for clinical practice and suggests a need for imaging of the radial artery after sheath insertion. [ABSTRACT FROM AUTHOR]

Chylous ascites is an extremely rare complication of laparoscopic presacral neurectomy (LPSN), and treatment is still controversial. Four patients undergoing LPSN for dysmenorrhoea or chronic pelvic pain were complicated with chylous ascites. Two were successfully treated with bipolar cauterization and one, after the failure of initial treatment by bipolar cauterization, was then effectively managed by compression with Gelform and closure of the peritoneum of the presacral area by suture through laparoscopy. The fourth patient had persistent chyle leakage from the drainage tube after electrocauterization and was finally cured by conservative management including removal of the drainage tube and a low-fat diet for 3 weeks. Chylous ascites has not been reported in laparoscopic presacral neurectomy. Management that is quick, effect and subjects the patients to the least amount of suffering is still unresolved. Repeated laparoscopy can be considered to identify the possibility of injury to lymphatic vessels, to relieve abdominal distention due to chyle accumulation, and to apply electrocauterization or compression with Gelform and closure of the peritoneum. Conservative treatment with a low-fat diet may need a longer time. The use of a drainage tube may provide negative pressure allowing a continuous leakage of chyle. However, more controlled study is required to identify the most proper and effective management. [ABSTRACT FROM PUBLISHER]

Objective: This study evaluates the outcomes of modified transvaginal mesh (TVM) Surelift in managing advanced pelvic organ prolapse (POP) over a 3-year follow-up period, focusing on surgical success, functional improvement, and sonographic findings., Methods: A retrospective review was conducted on 99 women who underwent Surelift System surgery for advanced POP Stage III and IV between July 2018 to January 2020. Objective evaluation included Pelvic Organ Prolapse Quantification (POP-Q), multichannel urodynamic (UDS), and introital 2D ultrasonographic measurement. Subjective evaluation uses validated questionnaires of Incontinence Impact Questionnaire-7(IIQ-7), Urogenital Distress Inventory-6(UDI-6), Pelvic Organ Prolapse Distress Inventory 6(POPDI-6), Colorectal Anal Distress Inventory-8(CRADI-8) and Pelvic organ prolapse/ Urinary Incontinence Sexual Questionnaire (PISQ-12). Outcomes were examined at 3 months, yearly and at 3 years postoperative. Secondary outcome included de novo or persistent urodynamic stress incontinence (USI) and surgical complications., Results: Eighty-five women were included in the final analysis. At 3 years postoperative, the objective cure rate was 94.1 % and subjective cure rate of 91.8 %. Ultrasonography revealed initial mesh elongation and thickening at first year, resolving by the third year, while the distance between the bladder neck and mesh remained stable. Significant improvement in POP-Q components (Aa,Ba,C,Ap,Bp and TVL of p < 0.001), UDS (p < 0.001) and all validated Quality of Life (QoL) questionnaires (p < 0.001) were seen. De Novo USI and persistent USI occurred in 31.5 %. Complications included vaginal mesh exposure requiring excision in 4.7 % of patients, and one intraoperative bladder injury corrected promptly., Conclusion: The Surelift System TVM demonstrates safety and efficacy in treating advanced anterior-apical POP, achieving high cure rates, secured mesh placement, and minimal complications at 3 years post-operative., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Mid urethral sling (MUS) surgery is a widely accepted and safe procedure performed for stress urinary incontinence (SUI) with excellent cure rate besides its minimal complications. There are various types of MUS which can be offered. In this review we collated published data on MUS surgery performed among Taiwanese women with SUI in search for the best techniques and its outcome. We reviewed 77 articles, searched using PubMed platform related to MUS in USI among Taiwanese women from 1998 to 2023.24 articles, total 2733 participants with at least 12 months follow up after MUS. Objective cure rate for trans-obturator tape (TOT), retropubic sling (TVT, tension vaginal tape), single incision sling (SIS) (Solyx) and SIS (MiniArc) are 80%-92%, 88%-94%, 87%-90% and 87%-91% respectively, while subjective cure is 60%-90% in TOT, 86% in SIS (Solyx) and almost 90% in SIS (MiniArc), Predictors for surgical failure analyzed in 5 papers of 1006 women. Identifiable risk includes low maximal urethral closure pressure, intrinsic sphincter deficiency, previous anti SUI or prolapse surgery, presence of neurogenic disease, constipation, decreased bladder sensation, age >65 years, high pad test, Diabetes, detrusor overactivity, post-menopausal, reduced postoperative urethral mobility and tape percentile. Subsequently we dwell into complications of each type of MUS. This review showed the evolution of MUS and its comparable therapeutic efficacy. However, with certain complication rates and predictors for failure. This will add value in preoperative counselling while taking into accounts patients' factors in choosing the appropriate types of MUS. Future research is needed on long term effectiveness and risk of future recurrence., Competing Interests: Declaration of interest All authors have no competing interest to disclose., (Copyright © 2024.

Introduction and Hypothesis: Surelift is a transvaginal synthetic mesh (TVM) kit that is intended to treat anterior and apical pelvic organ prolapse (POP). The kit can be configured to use an anterior-apical (Surelift) or anterior (Surelift A) approach. The aims of this study were to evaluate the short-term objective and subjective outcomes of the different approaches at the 1-year follow-up., Methods: From June 2018 to April 2021, a total of 280 patients with symptomatic advanced POP (stages III and IV) had surgery with the Surelift or Surelift A. The primary outcome was postoperative de novo stress urinary incontinence (SUI), as well as subjective evaluation based on the Urinary Distress Inventory 6 (question 3 score > 1) and Incontinence Impact Questionnaire 7, during the 1-year follow-up period. Secondary outcomes measured quality of life, the presence of lower urinary tract symptoms, and complications., Results: In total, 265 patients were assessed. Among these, 137 had Surelift, whereas 128 underwent Surelift A with SSF. At 1-year postoperative follow-up, de novo urodynamic stress incontinence occurred more frequently in the Surelift group than in the Surelift-A group (28.8% vs 9.1% respectively, p = 0.012). Additionally, Surelift patients had a higher rate of de novo SUI than Surelift A (33.2 vs 11.4 respectively, p = 0.013). Both study groups experienced improvements in their quality of life indicators., Conclusions: The Surelift device is a safe and effective technique of treating advanced-stage POP. De novo urine incontinence appears to be more common in the Surelift group than in the Surelift-A group. We found good anatomical outcomes and subjective relief in both study groups, with a low complication rate., (© 2024. The International Urogynecological Association.)

Introduction and Hypothesis: To assess the outcomes of mid-urethral sling (MUS) procedures for urodynamic stress incontinence (USI) following extensive pelvic reconstructive surgery (PRS) and identify risk factors for persistent USI (P-USI)., Methods: This retrospective study analyzed 84 women who underwent a staged approach to MUS for USI after PRS for advanced pelvic organ prolapse (Pelvic Organ Prolapse Quantification III and IV). The primary outcome was objective cure rate, defined by negative urine leakage on urodynamic study and a 1-h pad test weight of < 2 g. Subjective cure rate was through a negative response to question 3 of UDI-6., Results: The overall objective cure rate was 81.0%. The highest cure rate was observed in de novo USI (MUS-D; 89.7%) compared with women with persistent USD (MUS-P). Patients with overt SUI exhibited lower cure rates than those with occult SUI. Predictive factors for persistent USI were lower pre-operative maximum urethral closure pressure (MUCP; p = 0.031) and higher BMI in the MUS-P group than in the MUS-D group (p = 0.008). Subjective improvement was noted, especially in the MUS-D group, with a subjective cure rate of 78.6%. Those with MUS-D reported a higher impact on patient well-being post-surgery. No complications were observed after MUS surgery at follow-up., Conclusions: Overt USI, low MUCP and high BMI are independent predictors of persistent USI after a staged MUS approach after pelvic reconstructive surgery., (© 2024.

Objective: To evaluate the impact of extensive vaginal pelvic reconstruction surgery (PRS) on advanced pelvic organ prolapse (POP) patients with bladder outlet obstruction (BOO)., Methods: We conducted a single-center, retrospective analysis of women who received extensive vaginal pelvic reconstruction surgery for advanced POP (POP-Q ≥3) with BOO from January 2006 to January 2016. Data regarding preoperative evaluation, surgical procedure, and postoperative management were abstracted from medical records. Patients were considered to have BOO when detrusor pressure at maximum flow (D max ) was ≥20 cm H 2 O and peak flow rate (Q max ) was ≤15 mL/s. Patients with postoperative value of D max lower than 20 cm H 2 O or Q max higher than 15 mL/s were regarded as objectively cured., Results: A total of 1894 patients with POP stages III or IV were assessed. The incidence of BOO was 22.8% (431/1894) within this patient population of advanced POP. One year after the vaginal PRS, the objective cure rate of BOO was 98.1%. Urodynamic parameters showed a significant increase in Q max (P < 0.001), while D max (P < 0.001) and postvoid residual urine (PVR) (P < 0.001) were significantly decreased. Previous POP surgery, native tissue repair (NTR), PVR ≥200 mL, and maximal cystometric capacity (MCC) ≥500 mL increase the likelihood of persistent BOO in patients., Conclusion: Vaginal PRS demonstrated effectiveness in treating BOO in patients with advanced POP. Irrespective of the types of transvaginal mesh (TVM), using TVM achieved better outcome than did NTR. Previous POP surgery, preoperative PVR ≥200 mL, and MCC ≥500 mL were the risk factors predicting the failure of PRS in improving BOO., (© 2024 International Federation of Gynecology and Obstetrics.)

Purpose: The purpose of this study was to evaluate the benefits of a Bluetooth self-fitting device using an in situ hearing screening test and self-fitting processes., Method: Thirty Mandarin-speaking individuals (16 men and 14 women) with mild-to-moderate hearing loss participated in this study. The hearing screening test was conducted using neckband earphones of a Bluetooth self-fitting device controlled by a smartphone app. The hearing screening tests were compared with the pure-tone audiometry in an audiometric booth. The amplification benefits of the self-fitting program-aided condition were evaluated and compared with those of unaided and preset program-aided conditions using the Mandarin Hearing in Noise Test (MHINT) and questionnaires., Results: The pure-tone audiometry and hearing screening test results exhibited strong positive correlations at all test frequencies. In the environment with 90° noise, the sentence reception thresholds (SRTs) obtained for the self-fitting program-aided condition were significantly lower ( p = .032) than those obtained for the unaided condition, whereas no significant difference was observed between the preset program-aided and the unaided conditions. Moreover, the participants' satisfaction ratings for the devices were consistent with their MHINT results, with a strong positive correlation observed between satisfaction with self-fitting and user satisfaction in smartphone app's control, functionality, and learning. Younger participants were significantly more satisfied in learning to use the app., Conclusions: Bluetooth self-fitting devices can be used for simplified in situ hearing screenings with a sensitivity of 90.4%. The satisfaction ratings and improvements in SRTs indicate significant clinical benefits of the self-fitting program compared with the preset program, particularly in the 90°-noise environments.

Objective: Low Maximal Urethral Closure Pressure (MUCP) is linked to unfavourable outcome of anti-incontinence surgery, however the cut-off value varied within studies. This study aimed to predict the cut-off value of MUCP that contributes to poor outcome of Mid-Urethral Sling (MUS) surgery in Urinary Stress Incontinence (USI) patients., Materials and Methods: Records of 729 women underwent MUS procedure from January 2004 to April 2017 reviewed. Patients were divided into four MUCP groups, which were <20 cmH2O (≥20 and < 40) cmH2O (≥40 and ≤ 60) cmH2O and >60 cmH2O. Objective evaluation comprising 72-h voiding diary, multichannel urodynamic study (UDS) and post-operative bladder neck angle measurement. Subjective evaluation through validated urinary symptoms questionnaires. Primary outcome was objective cure rate of negative urine leak on provocative filling cystometry and 1-h pad test weight <2 g, and subjective cure rate was negative response to question 3 of UDI-6. Secondary outcome was identifying risk factors of cure failure for MUS in low MUCP groups. To identify the risk factors of cure failure, MUCP groups were narrowed down into <40 cmH2O or ≥40 cmH2O., Results: Total of 688 women evaluated. Overall objective cure rate was 88.2% with subjective cure rate of 85.9%. Objective and subjective cure rates were lower in groups with low MUCP <40 cmH2O. Failure of MUS correlate significantly in patients with low MUCP <40 cmH20, bladder neck angle <30° and Functional urethral length (FUL) < 2 cm., Conclusion: Women with MUCP <40cmH2O, bladder neck angle <30° and FUL < 2 cm are more likely to have unfavorable outcome following MUS surgery. We proposed the cut-off low MUCP <40cmH2O as predictor for fail MUS surgery in SUI patients., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024.

Objective: To evaluate the surgical outcomes and predictors of failure of Single Incision Mini Sling (Ophira) in women with urodynamic stress incontinence., Materials and Methods: Records of 115 women underwent anti-incontinence procedure using Ophira Mini Sling from June 2019 to September 2020 reviewed. Subjective evaluation was assessed using validated IIQ-7, UDI-6, POPDI-6 and PISQ-12 questionnaires. Multichannel urodynamics, 1-h pad test and 72-h voiding diary was performed as objective evaluation. Primary outcome was the objective cure rate of negative urine leak on provocative filling cystometry and 1-h pad test weight <2 g, and subjective cure rate was negative response to question 3 of UDI-6. Secondary outcome was to identify risk factors associated with failure for Ophira., Results: Total of 108 women were evaluated. The objective cure rate was 91.7% with subjective cure rate of 86.1%. Comparison of clinical outcome shows significant improvement of USI post-operatively (p < 0.001) and reflected in 1-h pad test (p < 0.001). Improvement in all subjective evaluation parameters is seen except for POPDI-6. Failure of Ophira correlate significantly in women age >66 years, presence of asthma, pre-operative Intrinsic Sphincter Deficiency (ISD), and Maximum Urethral Closure Pressure (MUCP) value < 40 cmH20., Conclusion: Ophira Single Incision Mini Sling is safe and effective treatment option for USI, showing high objective and subjective cure rates with low incidence of complications. Non-modifiable risks of age ≥66 years, asthma status, pre-operative intrinsic sphincteric deficiency and low maximal urethral closure pressure were the factors of failure for Ophira., Competing Interests: Declaration of competing interest The authors declare they have no competing interest., (Copyright © 2024.

Background: The Alere PBP2a SA Culture Colony Test is an FDA-cleared in vitro immunochromatographic assay for rapid detection of penicillin-binding protein2a (PBP2a) in Staphylococcus aureus ., Methods: We investigated the performance of the PBP2a SA Culture Colony Test with 78 coagulase-negative Staphylococcus (CoNS) isolates from different body sites, with the Vitek 2 Antimicrobial Susceptibility Test (AST) as a reference standard., Results: The CoNS species were 62 S. epidermidis ; 6 S. lugdenensis ; 3 S. hominis ; 2 S. capitis ; 2 S. haemolyticus ; and 1 each of S. simulans, S. auricularis, and S. warneri . Of the 78 CoNS isolates, 68 showed concordance in the PBP2a IC assay and Vitek 2 AST. Discordance was seen for 10 S. epidermidis isolates, which showed negative in the PBP2a assay, despite oxacillin-resistance detection using the Vitek 2 AST (66.7% sensitivity and 100% specificity). All non- S. epidermidis CoNS were identified with 100% concordance using the PBP2a IC assay and Vitek 2 AST., Conclusion: We demonstrated that, while the PBP2a IC assay has low sensitivity in determining the susceptibility of S. epidermidis to oxacillin, it highly accurately predicted the susceptibility of non- S. epidermidis CoNS to oxacillin. The diagnostic accuracy for non- S. epidermidis CoNS needs further assessment with more isolates to confirm our findings., (© 2024 The Author(s).)

Pelvic prolapse stands as a substantial medical concern, notably impacting a significant segment of the population, predominantly women. This condition, characterized by the descent of pelvic organs, such as the uterus, bladder, or rectum, from their normal positions, can lead to a range of distressing symptoms, including pelvic pressure, urinary incontinence, and discomfort during intercourse. Clinical challenges abound in the treatment landscape of pelvic prolapse, stemming from its multifactorial etiology and the diverse array of symptoms experienced by affected individuals. Current treatment options, while offering relief to some extent, often fall short in addressing the full spectrum of symptoms and may pose risks of complications or recurrence. Consequently, there exists a palpable need for innovative solutions that can provide more effective, durable, and patient-tailored interventions for pelvic prolapse. We manufactured an integrated polycaprolactone (PCL) mesh, reinforced with nano-hydroxyapatite (nHA), along with drug-eluting poly(lactic-co-glycolic acid) (PLGA) nanofibers for a prolapse scaffold. This aims to offer a promising avenue for enhanced treatment outcomes and improved quality of life for individuals grappling with pelvic prolapse. Solution extrusion additive manufacturing and electrospinning methods were utilized to prepare the nHA filled PCL mesh and drug-incorporated PLGA nanofibers, respectively. The pharmaceuticals employed included metronidazole, ketorolac, bleomycin, and estrone. Properties of fabricated resorbable scaffolds were assessed. The in vitro release characteristics of various pharmaceuticals from the meshes/nanofibers were evaluated. Furthermore, the in vivo drug elution pattern was also estimated on a rat model. The empirical data show that nHA reinforced PCL mesh exhibited superior mechanical strength to virgin PCL mesh. Electrospun resorbable nanofibers possessed diameters ranging from 85 to 540 nm, and released effective metronidazole, ketorolac, bleomycin, and estradiol, respectively, for 9, 30, 3, and over 30 days in vitro. Further, the mesh/nanofiber scaffolds also liberated high drug levels at the target site for more than 28 days in vivo, while the drug concentrations in blood remained low. This discovery suggests that resorbable scaffold can serve as a viable option for treating female pelvic organ prolapse.

The current practice of restoring the anatomical structure in the treatment of pelvic floor dysfunction includes implantation of synthetic sling, which carries potential complications. This study aimed to develop biological substitutes to improve tissue function using scaffolds as a support to the host cells, through formation of new tissue. Human amniotic fluid stem cells (hAFSCs) were seeded on synthetic mesh-scaffold of AlloDerm Regenerative Tissue Matrix (RTM), Poly-DL-lactico-glycolic acid (PLGA) mesh (VICRYL) and Polydioxanone (PDS) meshes. In vitro study evaluates the metabolic activity of hAFSCs seeded mesh-scaffolds. In vivo study involving Sprague-Dawley rats was performed by assigning into 7 groups of sham control with fascia operation, AlloDerm implant, PDS implant, PLGA implant, AlloDerm harvest with hAFSC (AlloDerm-SC), PDS harvest with hAFSC(PDS-SC) and PLGS harvest with hAFSC (PGLA-SC). In vitro study reveals cell viability and proliferation of hAFSC on mesh scaffolds varies between meshes, with AlloDerm growing the fastest. The biomechanical properties of tissue-mesh-complex tension strength declined over time, showing highest tension strength on week-1, deteriorated similar to control group on week-12. All hAFSC-seeded mesh provides higher tension strength, compared to without. This study shed the potential of synthetic mesh as a scaffold for hAFSC for the surgical treatment of pelvic floor dysfunction., (© 2024. The Author(s).)

Introduction and Hypothesis: Training in urogynecology is an important mission of the International Urogynecological Association (IUGA). Promoting official training programs in countries around the world is an integral part of this mission., Methods: The IUGA established the Fellowship Development Committee to develop a roadmap to assist countries to develop a professional training program in urogynecology. Two focus groups were created: the curricula topics focus group and the survey focus group. The curricula topics focus group is aimed at developing a list of subjects that can be the basis for a training syllabus. The survey focus group is aimed at understanding the main steps and the difficulties in establishing an official training program by interviewing representatives from both accredited and non-accredited countries and developing a roadmap for an official training program recognized by the local authorities., Results: The fellowship development committee included 13 members. The curricula topics focus group developed a format for the description of each included topic. Each topic had to include a description of the required related skills and procedures. Two curricula topics lists were created: one for basic training and a second for advanced training. The survey focus group conducted two table discussions with representatives from countries with accredited training programs and countries without accredited training programs. The comments of these meetings were summarized in documents submitted to the IUGA board of directors., Conclusion: The fellowship development committee studied the main hurdles to developing an official training program in urogynecology. The roadmap document should form the basis of the IUGA international initiative to assist countries around the world to develop an official training program in urogynecology recognized by the local authority., (© 2024.

Introduction and Hypothesis: Calistar-S is a single-incision synthetic mesh kit that addresses apical and anterior compartment prolapse. The aims of this study were to evaluate the short-term objective and subjective outcomes at the 1-year follow-up. The secondary objectives were to evaluate quality of life and lower urinary tract symptoms (LUTS) outcomes, as well as surgical complications., Methods: Records of 108 patients with symptomatic advanced pelvic organ prolapse (stages III and IV) who underwent prolapse surgery using the Calistar-S system from June 2018 to August 2022 were reviewed. The primary outcome was the objective cure of anterior and apical prolapse < stage 1, and the subjective cure was the negative response to questions 2 and 3 of the Pelvic Organ Prolapse Distress Inventory-6. Secondary outcomes measured quality of life, the presence of lower urinary tract symptoms, and complications., Results: A total of 101 patients were evaluated. The overall objective cure rate is 97% and the subjective cure rate is 92.1%. Good outcomes were seen in all three compartments. Secondary outcomes show significant improvement in all validated questionnaires. Persistence and de novo urinary incontinence were 15.2% and 18.2% post-operatively. There is one case of bladder injury and one case of vaginal mesh exposure., Conclusions: The Calistar-S System is a safe and efficient method for treating advanced-stage POP. We observed good anatomical results and subjective relief with a minimal complication rate. LUTS have also been positively affected, showing a high success rate. Additional studies are needed to establish the long-term efficacy of this system., (© 2024. The International Urogynecological Association.)

Background and Purpose: We present this current study to complement with mesh inlays plausible benefits (UPHOLD-LITE System) on available long-term study amidst FDA's concern on mesh complications. This study aims to assess the medium-term outcomes of UPHOLD-LITE system for treatment of advanced pelvic organ prolapse (POP) and its complications, and lower urinary tract symptoms., Methods: This is a retrospective case series of 53 months follow-up of 123 consecutive patients who underwent UPHOLD-LITE system. Objective outcome measures the anatomical correction of prolapse with POP-Q ≤ Stage 1. Subjective outcome was patient's feedback to questions 2 and 3 of POPDI-6. Secondary outcome measures the quality of life, presence of lower urinary tract symptoms and complications. Quality of life is assessed by validated questionnaires on Urogenital Distress Inventory 6 (UDI-6), Incontinence Impact Questionnaire 7 (IIQ-7), Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6), and Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire 12 (PISQ-12) at 1 and 3 years post-operatively., Results: Objective outcome at 1 and 3 years was at 96.7 % and 95.4 % respectively. The subjective cure was 95.1 % and 91.6 %. Five-year cumulative cure rate maintained at 87.2 %. Secondary outcomes observed improvement on UDI-6, IIQ-7, POPDI-6 and PISQ-12 postoperatively. Bladder outlet obstruction improved while de novo urodynamic stress incontinence (USI) increased slightly post surgically. Mesh erosion rate was 0.8 %., Conclusion: The UPHOLD-LITE system demonstrated good medium term anatomical correction of apical and anterior prolapse, with good subjective cure and improved quality of life. Whilst complication rate was low, slight increase in de novo USI was observed., (Copyright © 2024 Formosan Medical Association. Published by Elsevier B.V. All rights reserved.)

Study Objective: To determine the outcome of voiding function 1 year after pelvic reconstructive surgery (PRS) in women with bladder outlet obstruction (BOO)., Design: Retrospective cohort study., Setting: Tertiary referral hospital., Patients: A total of 1894 women underwent PRS for advanced pelvic organ prolapse (POP) stages 3 to 4 with urodynamic findings of BOO., Interventions: PRS., Measurements: The primary outcome measured was the resumption of normal voiding function, defined clinically with multichannel urodynamic testing at 1 year postoperatively. The secondary outcomes were to identify the different risk factors for persistence voiding dysfunction (VD) 1 year after PRS., Main Results: A total of 431 women with Pelvic Organ Prolapse Quantification stages 3 and 4, urodynamic study of maximum urinary flow rate ≤15 mL/s, and detrusor pressure at maximum flow ≥20 cm H 2 O were included. Resumption of normal voiding function was found in 91% (n = 392 of 431), whereas 9% (n = 39 of 431) remained to have VD 1 year postoperatively. Those with persistent VD, 20.5% (n = 8 of 39) remained having urodynamic diagnosis of BOO. Univariate and multivariate logistic regression revealed factors associated with postoperative VD were pre-operative maximal cystometric capacity ≥500 mL and postvoid residual volume ≥200 mL., Conclusion: VD may persist in women with BOO after PRS, particularly in those with preoperative maximal cystometric capacity of >500 mL and postvoid residual volume >200 mL., (Copyright © 2023 AAGL.

This study was to investigate urinary beta 3-adrenoceptor concentration as a biomarker for overactive bladder (OAB) and predictor of treatment outcomes in women receiving the beta 3-adrenoceptor agonist mirabegron. The study comprised 50 women identified with OAB and 35 women considered as healthy controls. All women with OAB received daily dosage of 50 mg of mirabegron for 12 weeks. Bladder diaries, OAB-related questionnaires, and global response assessment scale (GRAS) data were collected. Urinary beta 3-adrenoceptor concentration was measured through enzyme-linked immunosorbent assay. All OAB-related questionnaires and GRAS indicated improved posttreatment urinary health. After mirabegron treatment, the frequency of micturition and urgency episodes decreased, but the urinary beta 3-adrenoceptor/creatinine (Cr) ratio increased. The urinary beta 3-adrenoceptor/creatinine ratio was identified as a sensitive biomarker for OAB with a confidence interval of 0.656 to 0.856 (p < 0.001). A negative correlation (- 0.431, p = 0.040) between this biomarker and health-related quality of life (HRQL) scores. The Beta 3-adrenoceptor/Cr levels increased significantly in the treatment-responsive group, while they remained unchanged in the unsatisfactory outcome group. This study shows that 12 weeks of mirabegron treatment improves OAB symptoms and HRQL. Furthermore, urinary beta 3-adrenoceptor concentration may be a diagnostic biomarker for OAB., (© 2023.

Background: Clostridioides difficile (C. difficile) is a common hospital-acquired infection which can lead to major implications for patients and our health care system. In this study, we examine a policy change at a single-site Veterans Affairs Healthcare system that allowed bedside nurses to order C. difficile testing in addition to physicians on the time to obtain test results and initiate treatment., Methods: The time to receive results and initiate treatment were analyzed before and after the policy change, and between physicians and nurses using descriptive statistics and paired student t-tests. Variables associated with lower ordering times were also analyzed using logistic regression while adjusting for patient admission location and length of inpatient hospital stay., Results: The difference in time to obtain the result both before and after the policy change and between ordering provider type were both statistically significant (P < .05). In unadjusted models, nurses were associated with faster test results compared to physicians (OR (95% CI) 1.72 (1.45-2.05)., Conclusions: Allowing bedside nurses more autonomy to order the stool sample significantly decreased the amount of time to receive the results, potentially decreasing the risk of additional infections among patients and decreasing the economic burden on the hospital., (Published by Elsevier Inc.)

Introduction and Hypothesis: The objective was to investigate the surgical volume shifts for primary female stress urinary incontinence (SUI) over a 20-year period (1999-2018) in Taiwan., Methods: This was a retrospective cohort study based on Taiwan's National Health Insurance Research Database. We divided the time-frame into four periods: first period (1999-2003), second period (2004-2008), third period (2009-2013), and fourth period (2014-2018). The variables included major surgical types for SUI (retropubic urethropexy, pubovaginal sling, midurethral sling, etc.), surgeon gender, specialty, surgical volume (high ≥30, median 5-29, low <5), and hospital accreditation level. Reoperation rates within 1 year were analyzed as an outcome measurement., Results: A total of 51,018 patients were identified. Major surgical types increased significantly during the first three periods and slightly decreased during the fourth period. The proportion of surgical volume shifted from high- to medium-, and low-volume, but it reversed during the fourth period. The proportion of SUI surgeries decreased in medical centers, whereas it increased in regional and local hospitals. The proportion of SUI surgeries by female surgeons increased. Similar phenomena occurred in MUS. As for surgeon specialty, major surgical types were performed by gynecologists and urologists equally, whereas MUS were performed more by gynecologists than by urologists. Unexpectedly, 1-year reoperation rates were higher in high-volume surgeons., Conclusions: The surgical trend of SUI surgeries shifted from high- to medium-, and low-volume surgeons, medical centers to regional and local hospitals during the study periods. This implied surgical skills and performance spreading, which may have a great influence on patient and healthcare provider choice of treatment., (© 2022.

Introduction: The primary objective of this study is to determine the prevalence of overactive bladder (OAB) and detrusor overactivity (DO) in female patients who were referred for urodynamic study (UDS) because of lower urinary tract symptoms (LUTS). The secondary objective is to determine the subjective and objective differences between female OAB patients with and without DO., Materials and Methods: All female patients who underwent UDS for LUTS between June 2016 and September 2019 were retrospectively reviewed. Personal history, medical history, physical examination, and validated questionnaires were collected. One-hour pad test and multichannel urodynamic study was performed. All statistical analyses were conducted by SAS 9.4. P-value < 0.05 was considered statistically significant., Results: A total of 4184 female patients underwent UDS because of LUTS between June 2016 and September 2019; 1524 patients were analyzed for OAB or DO. The occurrence of OAB was 36.4%. The overall incidence of DO in OAB patients was 15.5%; 9.5% of all patients had DO findings on UDS, and 4.6% were incidental findings. There were significant differences among mean age, parity, ICIQ-UI SF, OABSS, POPDI-6, and all UDS parameters (except for maximal urethral pressure and pressure transmission ratio) between patients with and without DO. In patients with DO, there were no significant differences among age, parity, and BMI with or without OAB symptoms. However, there were significant differences among mean OABSS, ICIQ-UI SF, UDI-6, POPDI-6, IIQ-7, and pad test., Conclusions: Patients with DO are associated with older age, increased parity, greater urine leakage, and worse storage and micturition functions on UDS. Combinations of subjective and objective measurements are better predictive models for OAB patients., (© 2022. The International Urogynecological Association.)

Introduction: Low-energy extracorporeal shock wave therapy (LiESWT) is a new potential treatment for intractable interstitial cystitis/bladder pain syndrome (IC/BPS), and this paper will evaluate its therapeutic effects on IC/BPS., Materials and Methods: This prospective clinical trial enrolled 30 women who have been diagnosed with IC/PBS to receive LiESWT treatment at an intensity of 0.25 mJ/mm 2 and a frequency of 3 pulses/second, for a total of 3000 pulses within 8 weeks. And we assessed questionnaires (including O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI)), 3-day voiding diary, and urodynamic study at the following intervals: 4 weeks of LiESWT (W4), 8 weeks of LiESWT (W8), 1-month follow-up (F1), 3-month follow-up (F3) after LiESWT, and 1 year follow-up (F12)., Results: The primary outcome of questionnaires showed significant improvement of symptoms compared to baseline (W0), especially on ICSI(12.87 ± 3.44 before treatment and 7.87 ± 5.27 at F12, p < 0.05). 3-day voiding diary also revealed significant decrease in daytime voiding frequency (15.57 ± 5.22 times before treatment and 10.70 ± 4.21 times at F1, p < 0.05) and significant increase on average voiding volume (95.85 ± 35.30 mL before treatment and 161.27 ± 74.21 mL at F1, p < 0.05). However, there were no significant differences in all parameters of the urodynamic study., Conclusion: LiESWT can mitigate pain and lower urinary tract symptoms and improve the quality of life in IC/PBS patients, but does not increase the maximal cystometric capacity., (© 2022 Wiley Periodicals LLC.)

Introduction and Hypothesis: Our primary objective was to study objective and subjective outcomes of patients with urodynamic stress incontinence (USI) following Solyx™ at 3-year follow-up. Our secondary objective was to evaluate ultrasonographic tape and bladder neck position and mobility., Methods: Records of 88 women who received Solyx™ surgery between September 2015 and December 2017 were reviewed. Ultrasonographic sling evaluation was performed at 6 months and 3 years postoperatively. Primary outcomes were objective and subjective cure of stress incontinence, defined as no involuntary urine leakage during filling cystometry, 1-h pad test < 2 g and negative response to Urogenital Distress Inventory-6 Question 3., Results: Subjective and objective cure rates at 3 years were 85.2% and 87.5%, respectively, with no complications reported. QOL improvements were maintained. Bladder neck position and mobility had no significant change between 6-month and 3-year follow-up. Tape position demonstrated significant shifts in the y-axis at both rest and Valsalva and in the x-axis at Valsalva between 6 months and 3 years; overall mobility was unchanged. Percentile of sling location remained unchanged at 60.1%, as did percentage of urethral kinking (67.9%) achieved. Risk factors for failure were bladder neck hypomobility postoperatively and no urethral kinking postoperatively., Conclusions: There was good sustained objective and subjective cure with improved QOL in women who underwent Solyx™ for USI at 3-year follow-up. Ultrasonographic evaluation showed a tape position shift upwards and backwards with unchanged tape and bladder neck mobility. Percentile of sling location and rates of dynamic kinking were maintained., (© 2021. The International Urogynecological Association.)

Objective: Due to the COVID-19 pandemic, there is a dramatic drop in in-person residency training due to the implementation of isolation and triage measurements. Here, we propose a new flipped classroom clinical skill training model utilizing a combination of pre-workshop, web-based learning and hands-on workshop that shortens in-person contact time to maintain residency training during the pandemic. Effectiveness of this training model was evaluated with a pre-test and post-test skills competency assessment, two-way feedback, and a five-point Likert scale structured survey questionnaire., Materials and Methods: The workshop was conducted in a flipped classroom fashion by the obstetrics and gynecology (OBGYN) department of a single tertiary teaching medical center covering topics from five OBGYN subspecialities. Every topic consisted of a pre-workshop, web-based, mini lecture (PWML) followed by a hands-on workshop (HW). All first to fourth year OBGYN residents were invited to attend the workshop. All the trainees were required to complete the PWML prior to the day of HW. The workshop consisted of rotational station for each topic and was conducted within one afternoon. A 0-100-point scale pre-test and post-test skills competency evaluation were performed for each station and was assessed by the attending doctor or fellow doctor of each subspeciality. Two-way feedback was done after the post-test evaluation. A five-point Likert scale structured survey instrument consisting of participant's perceptions of the workshop design, relevance to clinical practice, and quality of instructors and materials was created during the curriculum development process and sent to each participant one month after the workshop., Results: A total of 19 residents including five first-year, six second-year, three third-year, and five fourth-year residents completed the entire pre-workshop lecture, workshop, pre-test, and post-test. For all residents, the average post-test score of 5 stations was 95 and was significantly higher than the pre-test score of 60 (p < 0.001). For both junior residents and senior residents, the average post-test scores of 5 stations were also significantly higher than pre-test scores (p < 0.001). Survey generated one month after the workshop showed a high overall satisfaction with the workshop instructors on their professional knowledge, communication skills, and interactions between the instructors and trainees. The average satisfaction scores for manipulation of vaginal breech delivery (VBD), semen analysis (SA), cervical conization (CC), obstetrics anal sphincter injury (OASIS), and laparoscopic suture techniques (LST) were 4.84, 4.96, 4.92, 4.88, and 4.92, respectively The average score for practical application of the training materials, class design and teaching method, overall satisfaction of the session, and time scheduling was 4.84, 4.96, 4.96, and 4.48, respectively. The entire HW was completed within 180 min and was carried out within half a day., Conclusion: With the implementation of isolation and triage measures in the COVID-19 pandemic, there is a dramatic drop in in-person exposure to all aspects of the residency training, in particular, non-emergent surgeries. Utilization of PWML saved 1/3 of in-person time and the entire workshop was completed within 180 min that could be carried out within half a day. The decrease of person-to-person contact time during the COVID-19 pandemic is necessary while still providing curriculum-based residency training in spite of decreased hands-on experience., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2022.

Background: Adenosine triphosphate (ATP)-based monitoring systems can detect the amount of organic matter that remains on hospital surfaces after cleaning. We evaluated an ATP-based monitoring system in assessing contamination of high touched objects in rooms occupied by patients on methicillin resistant S. aureus precautions., Methods: We compared the ATP to standard aerobic cultures as well as to gloved hand culture to predict risk of healthcare-worker hand contamination., Results: More than a third of high touch object surfaces were measured unclean with ATP yet only reflects about 5% chance of contaminating healthcare-workers' hands., Conclusions: Our study emphasizes the shortcomings of using the ATP system even in pathogen specific environment such as surfaces in methicillin resistant S. aureus rooms., (Published by Elsevier Ltd on behalf of Tsinghua University Press.)

Introduction and Hypothesis: To analyze the immunochemical and urodynamic outcomes after partial versus complete excision of transvaginal polypropylene mesh (PPM) from pelvic walls of rats., Methods: Forty-eight female Sprague-Dawley (SD) rats were randomly distributed into seven groups: control, mesh total removal 60 days (M-T 60D), mesh total removal 180 days (M-T 180D), mesh partial removal 60 days (M-H 60D), mesh partial removal 180 days (M-H 180D), sham 60 days (Sham 60D), and sham 180 days (Sham 180D). In the mesh groups, PPM was inserted and partially (0.3 × 0.3 cm) or completely removed 30 days later. In the Sham group, the space between the vagina and bladder was dissected without placing or removing the synthetic mesh at day 1 and day 30 later. Urodynamic studies, immunochemical analysis, and Western blot were done at days 60 and 180., Results: The M-T 60D voiding pressure was significantly decreased compared to the Sham 60D and M-H 60D. The voiding interval of M-T 60D was significantly shorter than that of M-H 60D. In the M-T 60D and M-T 180D groups, the leak point pressure was significantly less than in their corresponding sham groups. IL-1 and TNF-α were significantly more intense in M-T 60D compared to M-H 60D and Sham 60D. NGF was significantly greater in M-T 60D compared to Sham 60D. There were no significant differences in MMP-2 and CD-31s throughout the group., Conclusion: Total mesh excision incites a host inflammatory response and transitory lower urinary tract dysfunction. Despite the good outcomes after total excision, the invasiveness and surgical risk associated with repeated procedures should not be underestimateded., (© 2021.

Introduction and Hypothesis: Our primary objective was to study outcomes of patients with intrinsic sphincter deficiency (ISD) following mid-urethral slings (MUS) at 1-year. Our secondary objective was to delineate factors affecting success in these patients., Methods: Six hundred eighty-eight patients who had MUS between January 2004 and April 2017 were reviewed retrospectively; 48 women were preoperatively diagnosed with ISD. All completed urodynamic studies and validated quality-of-life (QOL) questionnaires at baseline and 1 year. Primary outcomes were objective and subjective cure of stress incontinence, defined as no involuntary urine leakage during filling cystometry and 1-h pad test < 2 g and negative response to Urogenital Distress Inventory-6 Question 3. Ultrasound was performed to determine tape position, urethral mobility and kinking at 1 year., Results: Women with ISD had significantly lower objective and subjective cure rates of 52.1% and 47.9%, respectively, compared to an overall of 88.2% and 85.9%. QOL scores significantly improved in those with successful surgeries. The sling type did not make a difference. Multivariate logistic regression identified reduced urethral mobility [OR 2.11 (1.24-3.75)], lower maximum urethral closure pressure (MUCP) [OR 1.61 (1.05-3.41)] and tape position [OR 3.12 (1.41-8.71)] to be associated with higher odds of failed slings for women with ISD., Conclusions: Although there are good overall success in women undergoing MUS, those with ISD have significantly lower cure rates at 1 year. Factors related to failure include reduced urethral mobility, low MUCP and relative tape position further away from the bladder neck. Optimal management of patients with ISD and reduced urethral mobility remains challenging., (© 2021. The International Urogynecological Association.)

Introduction and Hypothesis: The objective was to identify incidence and risk factors of de novo urgency and detrusor overactivity (DO) following mid-urethral slings (MUS) in patients with urodynamic stress incontinence (USI) without urgency., Methods: A total of 688 women between January 2004 and July 2017 were reviewed retrospectively. De novo urgency was established with a positive response to question 2 on the Urogenital Distress Inventory-6 questionnaire (UDI-6). Objective cure of USI is no involuntary urine leakage during filling cystometry and pad test < 2 g. Subjective cure of stress urinary incontinence (SUI) is defined as a negative response to question 3 on UDI-6. Multivariate logistic regression was used to identify risk factors for failure., Results: Forty-four out of 688 women (6.4%) developed de novo urgency, with 16 out of 688 (2.3%) demonstrating de novo DO. Subjective cure for women with de novo urgency was significantly lower at 35 out of 44 (79.5%) compared with 556 out of 644 (86.3%) in those with no urgency (p < 0.001). Objective cure for women with de novo DO was significantly lower at 8 out of 16 (50%) compared with 599 out of 672 (89.1%) in those with detrusor stability (p < 0.001). Quality of life improved for all. Age ≥ 66 (OR, 1.23; 1.07), increased bladder sensation (OR, 4.18; 3.80), lower bladder capacity (OR, 5.28; 4.97), lower maximum urethral closure pressure (OR, 2.32; 5.20), and pad test > 100 g (OR, 1.08; 1.15) were independent risk factors for de novo urgency and DO. Diabetes (OR, 1.32) was an independent predictor of de novo urgency., Conclusion: Cure is significantly reduced in women who report symptoms of de novo urgency or demonstrate DO after MUS at 1 year. Independent risk factors include age ≥ 66, increased bladder sensation, lower bladder capacity, lower maximum urethral closure pressure, greater pad loss, and diabetes., (© 2021.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is not only a chronic urinary bladder pain syndrome but is also associated with multifactorial etiology. Our study aimed to test the hypothesis that IC/BPS is associated with subsequent increased risks of outpatient visits and hospitalizations. Using nationwide database, the diagnoses were based on the International Classification Codes (ICD-9-CM) (595.1) of at least three outpatient services during 2002-2008, (n = 27,990) and cystoscopic finding Hunner type and/or glomerulation with pre-audit criteria. All recruited cases monitored for subsequent outpatient visits and hospitalizations for 2 years, including all-cause and specialty-specific departments, were classified according to medical specialty and age group (<40, 40-60, ≥60 years of age). IC/BPS patients have more overall outpatient department (OPD) visits and an overall adjusted incidence rate ratio (IRR) of 1.64. As for specialty, IRRs were higher in psychiatry (2.75), Chinese medicine (2.01), and emergency medicine (2.00), besides urology and gynecology. The IRRs decreased as age advanced (2.01, 1.71, and 1.44, respectively), except for gynecology (2.42, 2.52, and 2.81). A similar phenomenon happens in hospitalization with IRR of 1.69. Due to claim data characteristics, whether ulcer type IC/BPS findings can be deductive to non-ulcer type remains inclusive. Current results indicate the impacts of healthcare burden in broad spectrum about IC/PBS patients. IC/BPS has been suggested to be associated with lower threshold of healthcare visits and some coexisting disease and is comprised of systemic dysregulation, and is beyond the scope of local bladder-urethra disease. Adequate recognition of associated or comorbid factors and possible recommendation or referral for IC/BPS patients can help provide better healthcare quality., Competing Interests: The authors have declared that no competing interests exist.

Background: Nucleoside and nucleotide reverse transcriptase inhibitors (NRTIs) have become a standard treatment for both HIV and hepatitis B virus (HBV) infections. Tenofovir disoproxil fumarate (TDF) has been associated with kidney injury and possible long-term damage in patients with HIV. Few studies have examined whether this holds true for patients treated for HBV., Methods: Data were gathered from the Veterans Health Administration Corporate Data Warehouse between July 1, 2005 and July 31, 2015. Patients aged ≥ 18 years with HBV infection and prescribed a NRTI for > 1 month were included in the study and followed for 36 months. Patients with HIV infection were excluded, and patients treated with combination TDF/emtricitabine were analyzed separately from patients receiving only TDF. A linear mixed model was used to examine the effects of time and specific agent on renal function, which was measured with estimated glomerular filtration rate (eGFR) at various time intervals., Results: There were 413 incidences of NRTI use in 308 subjects during the 10 years of the study with 39 cases of TDF use. There was a significant fixed effect of time, with eGFR reduction of 4.6 mL/min ( P < .001) over the course of the study for the full cohort, but the effects of each medication were not significant., Conclusions: This multicenter, retrospective study did not demonstrate an association between TDF use and a greater degree of kidney injury compared with other NRTIs in patients with HBV, but further studies are warranted., Competing Interests: Author disclosures The authors report no actual or potential conflicts of interest with regard to this article., (Copyright © 2021 Frontline Medical Communications Inc., Parsippany, NJ, USA.)

We developed biodegradable drug-eluting prolapse mats using solution-extrusion 3D printing and coaxial electrospinning techniques. The mats were composed of polycaprolactone (PCL) mesh and lidocaine-, estradiol-, metronidazole-, and connective tissue growth factor (CTGF)-incorporated poly(lactic- co -glycolic acid) (PLGA) nanofibers that mimic the structure of the natural extracellular matrix of most connective tissues. The mechanical properties of degradable prolapse membrane were assessed and compared to commercial non-degradable polypropylene knitted meshes clinically used for pelvic organ prolapse (POP) repair. The release behaviors of the drug-loaded hybrid degradable membranes were also characterized. The experimental results suggest that 3D-printed PCL meshes exhibited comparable strengths to commercial POP meshes and survived through 10,000 cycles of fatigue test without breakage. Hybrid PCL meshes/PLGA nanofibrous membranes provided a sustainable release of metronidazole, lidocaine, and estradiol for 4, 25, and 30 days, respectively, in vitro. The membranes further liberated high levels of CTGF for more than 30 days. The animal tests show that the mechanical property of PCL mesh decreased with time, mainly due to degradation of the polymers post-implantation. No adverse effect of the mesh/nanofibers was noted in the histological images. By adopting solution-extrusion 3D printing and coaxial electrospinning, degradable drug-eluting membranes can be fabricated for POP applications.

In this study, we conducted a prospective survey of a convenience sample of high touch objects using adenosine triphosphate bioluminescence surface sample readings, aerobic cultures, and gloved hand methicillin-resistant Staphylococcus aureus imprint cultures to assess inpatient room cleanliness. We demonstrated that thoroughness of cleaning is improved with housekeeping education and feedback and that the addition of automated decontamination with pulsed UV irradiation provides further benefit in decontamination and subsequent risk for health care worker hand contamination., (Published by Elsevier Inc.)

Aims: Interstitial cystitis (IC) is a chronic pain syndrome that is characterized by suprapubic pain upon bladder filling. Bletilla striata, a well-known traditional Chinese herb with established efficacy in wound healing and anti-inflammation, was hypothesized to improve the symptoms of IC possibly though forming a physical barrier that could isolate the bladder tissue from irritants. This study was conducted to evaluate the beneficial effects of intravesical treatment with B. striata extract solution (BSES) on visceral pain and bladder function of rats with zymosan-induced IC., Methods: Thirty female rats were randomly divided into control group, zymosan-induced cystitis rats treated with normal saline (Z + NS), and zymosan-induced cystitis rats treated with BSES (Z + BSES). All rats underwent evaluation for abdominal withdrawal reflex (AWR) scores to assess visceral hypersensitivity, cystometrography, and electromyogram (EMG) of both external urethral sphincter and bladder detrusor. Data were analyzed by one way analysis of variance., Results: The Z + NS group had an increased visceral hypersensitivity as compared to control group. Rats treated with BSES (Z + BSES group) had decreased AWR scores and amplitude of bladder detrusor-EMG. Besides, BSES treatment improved overactive bladder with significant effects on the extend of micturition interval and increase of storage of urine., Conclusions: Intravesical instillation of BSES can significantly alleviate zymosan-induced visceral hypersensitivity and bladder overactivity associated with IC. This study suggested that intravesical instillation with BSES might be a promising treatment for IC., (© 2021 Wiley Periodicals LLC.)

Transvaginal mesh (TVM) insertion for the treatment of pelvic organ prolapse (POP) is significantly associated with lower failure rates, although its use remains controversial due to the potential risk of mesh-related complications. In this review, we collected the published literature regarding the use of TVM to treat POP in an attempt to assess both the efficacy and complications related to TVM usage in Taiwan. We searched 25 English language articles using PubMed related to TVM in Taiwan from 2010 to 2019. The present article focuses on the efficacy and complications of TVM and analyzes the data. There were 25 studies on TVM selected for this review. Regarding their success rate, 21 out of the 22 studies (95.5%) had more than a 90% objective success rate. Twenty studies (90.9%) had less than 10% major complications of TVM. Twenty out of the 25 studies (80.0%) had 5% or less mesh exposure. For self-cut TVM and the later single-incision TVM, both the complication rates and exposure rates decreased. The rate of de novo dyspareunia ranged from 2.6% to 14.3%, and the incidence decreased yearly from 2011 to 2019. This review showed both the high treatment efficacy and low complication rate of TVM usage for the short-term treatment of POP in Taiwan. However, a longer-term study is needed to draw a conclusion regarding the safety of this treatment., Competing Interests: Declaration of competing interest There are no conflicts of interest for any of the authors., (Copyright © 2021.

With the advance of minimally invasive surgery (MIS), the surgical trends of hysterectomy changed significantly during past 2 decades. Total number (age-standardized) of all types of hysterectomy decreased, which may be due to the availability of some other alternatives, e.g. hysteroscopy, laparoscopic myomectomy. However, laparoscopic hysterectomy (LH) still remains the mainstream of surgical treatment. LH significantly increases for benign gynecologic conditions in Taiwan and worldwide. The increase of LH was accompanied with decrease of TAH; VH kept stationary, and SAH increased slightly. The increase in popularity of LH and SAH; provides evidence of surgical trends and a paradigm shift for hysterectomy. This time-frame shift suggests LH has reached a u during the later years. Older patients tend to receive AH, while middle-aged women tend to receive LH. Oder surgeons tend to perform AH, while younger surgeons tend to perform LH. However, all type hysterectomy and LH were more commonly performed by older surgeons aged over 50 years. It means both patients and surgeons became older during the time-frames. The above phenomena may also happen due to less young surgeons entered in the gynecologic practice. Most of the LHs were performed by high-volume surgeons, however, there is a shift from high-volume, to medium- and low-volume surgeons. The above scenario may be due to the wide spread of LH techniques. Surgical volume has important impacts on both complications and costs. The high-volume surgeons have lower complications, which result in lower costs. In the future, how to increase the use of LH, to improve the training and monitoring system deserves more attentions., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Gynecology and Minimally Invasive Therapy.)
