Ablation for Atrial Fibrillation in Patients With Rare Pathogenic Variants in Cardiomyopathy and Arrhythmia Genes.

BACKGROUND: Patients with rare, pathogenic cardiomyopathy (CM) and arrhythmia variants can present with atrial fibrillation (AF). The efficacy of AF ablation in these patients is unknown. OBJECTIVE: This study tested the hypotheses that: 1) patients with a pathogenic variant in any CM or arrhythmia gene have increased recurrence following AF ablation; and 2) patients with a pathogenic variant associated with a specific gene group (arrhythmogenic left ventricular CM [ALVC], arrhythmogenic right ventricular CM, dilated CM, hypertrophic CM, or a channelopathy) have increased recurrence. METHODS: We performed a prospective, observational, cohort study of patients who underwent AF catheter ablation and whole exome sequencing. The primary outcome measure was ≥30 seconds of any atrial tachyarrhythmia that occurred after a 90-day blanking period. RESULTS: Among 1,366 participants, 109 (8.0%) had a pathogenic or likely pathogenic (P/LP) variant in a CM or arrhythmia gene. In multivariable analysis, the presence of a P/LP variant in any gene was not significantly associated with recurrence (HR 1.15; 95% CI 0.84-1.60; P = 0.53). P/LP variants in the ALVC gene group, predominantly LMNA, were associated with increased recurrence (n = 10; HR 3.75; 95% CI 1.84-7.63; P < 0.001), compared with those in the arrhythmogenic right ventricular CM, dilated CM, hypertrophic CM, and channelopathy gene groups. Participants with P/LP TTN variants (n = 46) had no difference in recurrence compared with genotype-negative-controls (HR 0.93; 95% CI 0.54-1.59; P = 0.78). CONCLUSIONS: Our results support the use of AF ablation for most patients with rare pathogenic CM or arrhythmia variants, including TTN. However, patients with ALVC variants, such as LMNA, may be at a significantly higher risk for arrhythmia recurrence.

Robotic parastomal hernia repair in Ileal-conduit patients: short-term results in a single-center cohort study.

PURPOSE: To describe and evaluate safety and feasibility of the robotic modified Sugarbaker technique with intraperitoneal underlay mesh (IPUM) for repairing parastomal hernias associated with ileal conduits (ICPSH). METHODS: This retrospective, single-center cohort study analyzed data from 15 adult patients who underwent robotic ICPSH repair using the modified Sugarbaker IPUM technique between July 2021 and July 2023. The primary endpoints were hernia recurrence rates and 30-day morbidity. Secondary endpoints included length of stay, conversion to open surgery, 30-day readmission, and 30-day reoperation. RESULTS: The mean patient age was 69.1 years, and 53.3% were female. Most patients (86.6%) had undergone radical cystectomy as the index surgery. The mean operative time was 249 min, with no conversions to open surgery. The 30-day complication rate was 26.7%, and the mean hospital stay was 3.6 days. No hernia recurrences, hydronephrosis, rise in creatinine or distended conduit on imaging suggesting poor drainage were observed during a mean follow-up of 15.2 months. CONCLUSIONS: The robotic modified Sugarbaker IPUM technique appears safe and feasible for PSH repair in IC patients, with promising short-term outcomes. Further studies with larger cohorts and longer follow-up are needed to confirm its long-term efficacy and establish its role in ICPSH management.

Frailty Among Bladder Augmentation Patients: Healthcare Utilization and Perioperative Outcomes.

OBJECTIVE: To study the impact of frailty on healthcare utilization in patients undergoing benign pelvic reconstructive surgery; specifically, bladder augmentation. METHODS: American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) was queried for adults undergoing bladder augmentation between 2005 and 2022. The Five-Item Frailty Index (FFI) was used to assign a score from 0 to 6. Healthcare resource utilization (HRU) was defined by 4 metrics: prolonged length of stay (PLOS), 30-day postoperative readmissions (AR), discharge to continued care (ie, non-home location) (DCC), overall HRU which is a composite of the other 3 outcomes, and complications. Multivariable risk-adjusted regression models were generated. RESULTS: Three hundred sixty-four patients were included, the majority being white (71%), female (52%), with a median age of 49 years. After controlling for baseline variables, higher FFI score (≥2) was independently associated with PLOS (OR 1.90 [1.02-3.53], P = .04), DCC (OR 2.76 [1.24-6.15], P = .01), and greater overall HRU (OR 2.64 [1.29-5.40], P = .008) but not AR (OR 2.27 [0.99-5.19], P = .05). Higher frailty (FFI ≥2) was independently associated with experiencing any complication (OR 2.32 [1.16-4.64], P = .02) as well as major complications (Clavien ≥3) (OR 2.56 [1.15-5.7] P = .02). CONCLUSION: Frail adults undergoing bladder augmentation experience greater HRU and complications. This highlights the importance of frailty in benign pelvic reconstructive surgery and stresses the need for interventions to optimize frail patients.

Robotic Excision of Intravesical Mesh Following Transvaginal Mesh-Based Prolapse Repair.

INTRODUCTION AND HYPOTHESIS: We describe the surgical management of intravesical mesh perforation following transvaginal mesh surgery for pelvic organ prolapse. METHODS: A 73-year-old woman presented with intravesical mesh perforation 17 years following transvaginal mesh-based prolapse repair at an outside hospital. The patient presented with intermittent hematuria and recurrent urinary tract infections. Cystoscopy demonstrated an approximately 3-cm area of intravesical mesh with associated stone spanning from the bladder neck through the left trigone and ureteral orifice. A robotic-assisted transvesical mesh excision and left ureteroneocystostomy was carried out. Robotic-assisted repair was performed transvesically via transverse bladder dome cystotomy. Dissection was carried out circumferentially around the mesh in the vesicovaginal plane, including a 1-cm margin of healthy tissue. The eroded mesh was excised, and the vaginal wall and bladder were closed with running absorbable sutures. Given the location of the mesh excision and repair, a left ureteral reimplantation was performed. The transverse cystotomy was closed and retrograde bladder filling with methylene blue-stained saline confirmed watertight repairs, with no vaginal extravasation. RESULTS: The patient was discharged the following morning and had an uneventful recovery, including transurethral indwelling catheter removal at 2 weeks after CT cystogram and subsequent ureteral stent removal at 6 weeks postoperatively. At 2-month follow-up she had no new urinary symptoms or obstruction of the ureteral reimplantation on renal ultrasound. CONCLUSIONS: A robotic-assisted approach is a feasible option for managing transvaginal prolapse mesh perforation into the bladder. Pelvic surgeons must be well equipped to handle transvaginal mesh complications in a patient-specific manner.

Multisite Validation of a Functional Assay to Adjudicate SCN5A Brugada Syndrome-Associated Variants.

BACKGROUND: Brugada syndrome is an inheritable arrhythmia condition that is associated with rare, loss-of-function variants in SCN5A. Interpreting the pathogenicity of SCN5A missense variants is challenging, and ≈79% of SCN5A missense variants in ClinVar are currently classified as variants of uncertain significance. Automated patch clamp technology enables high-throughput functional studies of ion channel variants and can provide evidence for variant reclassification. METHODS: An in vitro SCN5A-Brugada syndrome automated patch clamp assay was independently performed at Vanderbilt University Medical Center and Victor Chang Cardiac Research Institute. The assay was calibrated according to ClinGen Sequence Variant Interpretation recommendations using high-confidence variant controls (n=49). Normal and abnormal ranges of function were established based on the distribution of benign variant assay results. Odds of pathogenicity values were derived from the experimental results according to ClinGen Sequence Variant Interpretation recommendations. The calibrated assay was then used to study SCN5A variants of uncertain significance observed in 4 families with Brugada syndrome and other arrhythmia phenotypes associated with SCN5A loss-of-function. RESULTS: Variant channel parameters generated independently at the 2 research sites showed strong correlations, including peak INa density (R2=0.86). The assay accurately distinguished benign controls (24/25 concordant variants) from pathogenic controls (23/24 concordant variants). Odds of pathogenicity values were 0.042 for normal function and 24.0 for abnormal function, corresponding to strong evidence for both American College of Medical Genetics and Genomics/Association for Molecular Pathology benign and pathogenic functional criteria (BS3 and PS3, respectively). Application of the assay to 4 clinical SCN5A variants of uncertain significance revealed loss-of-function for 3/4 variants, enabling reclassification to likely pathogenic. CONCLUSIONS: This validated high-throughput assay provides clinical-grade functional evidence to aid the classification of current and future SCN5A-Brugada syndrome variants of uncertain significance.

Open and Robotic Uretero-enteric Stricture Repair: Early Outcomes and Complications.

Objective: To characterize our single institutional experience with robotic and open uretero-enteric stricture (UES) repair. Materials and Methods: We queried our ureteral reconstructive database for UES repair between 01/2017 and 10/2023. Patients with <3 months follow-up were excluded. Prior to surgery, patients underwent ureteral rest (4 weeks) with conversion to nephrostomy tube. Clinical characteristics, complications, reconstructive success (uretero-enteric patency), need for repeat intervention, and renal function were assessed in patients undergoing open and robotic UES reconstruction. Results: Of 50 patients undergoing UES repair during the study period, 45 were included for analysis due to complete follow-up (34 [76%] robotic and 11 [24%] open repair). UES repair was performed in 50 renal units a median of 13 months (interquartile range 7-30) from index surgery, and most often involved the left renal unit (34/50; 68%). Compared with robotic, open cases were significantly more likely to have undergone open cystectomy (100% vs 68%, p = 0.04), have longer strictures (median 4 vs 1 cm, p < 0.001), require tissue substitution (27% vs 3%, p = 0.04), and have lengthier postoperative hospitalization (5 vs 2 days, p < 0.001). There was no significant difference in total operative time (410 vs 322 minutes) or 30d major complications (18% vs 21%). At a follow-up of 13 months, per patient reconstructive success was 100% (11/11) for open and 97% (33/34) for robotic, respectively. Conclusion: In select patients with short UES unlikely to require advanced reconstructive techniques, a robotic-assisted approach can be considered. Careful patient selection is associated with limited morbidity and high reconstructive success.

Development of the Vietnamese Rape Myths Acceptance Scales: A Web-Based Survey of Young Adults.

Rape myths-false but widely held beliefs that serve to deny and justify sexual aggression-present a major barrier to reporting and prevention of sexual violence in Vietnam and globally. Based on a parent study aimed at reducing sexual violence at two universities in Hanoi, we developed and assessed a contextualized measure of rape myths among young people in Vietnam. Items from previously validated rape myth acceptance (RMA) scales and data from qualitative research informed the development of 50 items, which were administered to Vietnamese 18-24-year-olds (n = 2,756 total, n = 1,798 cisgender women) via an anonymous link in February 2021. We used factor analysis to explore and test factor structure and multi-group factor analysis to assess measurement equivalence across gender. We calculated item-level discrimination and difficulty parameters and visualized information curves using item response theory analysis, informing the development of a short form. Four hypothesized subconstructs identified in the qualitative data emerged as factors: (1) "He didn't mean to"; (2) "She asked for it"; (3) "It wasn't really rape"; and (4) "Rape is a deviant event." A fifth factor, "She didn't protect herself," included four items from formative data. Confirming formative findings and prior literature, cisgender women had lower RMA than cisgender men, particularly on items related to victim-blaming. The Vietnamese Rape Myths Acceptance Scales were internally consistent and equivalent between cisgender men and women, capturing elements specific to the Vietnamese context and providing a tool for campus climate surveys and evaluations of sexual violence prevention programs.

Ring Chromosome 14 with a Terminal 14q32.33 Deletion.

OBJECTIVES: Ring chromosome 14 is a rarely observed chromosomal abnormality characterized by a circular, ring-like appearance in one or both copies of chromosome 14. Ring chromosome 14 syndrome (OMIM #616606) is marked by global developmental delays, drug-resistant epilepsy, microcephaly, and ocular abnormalities. To date, fewer than 100 cases of ring chromosome 14 syndrome have been described in the medical literature. We describe a case of ring chromosome 14 and its clinical presentation in a 10-year-old female, adding to the literature about this rare condition.

High Rates of Discordant Ureteral Perfusion During Open Ureteral Reconstruction With Indocyanine Green: Does Near-Infrared Fluorescence Imaging Change Management or Stricture Outcomes?

OBJECTIVE: To determine the role of near-infrared fluorescence imaging (NIFI) combined with indocyanine green (ICG) to assess ureteral tissue perfusion in a benign genitourinary reconstruction cohort with a high prevalence of prior abdominopelvic radiation and surgery. MATERIALS AND METHODS: A prospective, single-surgeon series, between June 2018 and April 2022, of patients who underwent open genitourinary reconstructive surgeries in which NIFI/ICG was utilized to intraoperatively assess ureteral tissue perfusion prior to ureteral anastomosis. Primary outcome was ureteroanastomotic stricture (UAS). Secondary outcomes included impact of NIFI/ICG on surgical decision-making and ureter resection length. RESULTS: Thirty nine patients, median age 66, underwent 40 multimodality reconstructive surgeries during which NIFI/ICG was utilized in the open setting. Radiation-induced etiology was present in 32 of 40 (80%) patients. UAS occurred in 1 of 57 (1.8%) anastomoses with median follow-up of 23.4 months. Use of NIFI/ICG changed intraoperative decision-making in 63% of cases. Change in intraoperative decision-making was more common in patients with prior abdominopelvic radiation (66%) compared to non-radiated patients (13%), P = .007. Discordance between subjective (white-light) and objective (NIFI/ICG) ureteral perfusion (white-light) occurred in 61% of ureters. Mean length of resected ureter was higher following objective assessment with NIFI/ICG (3.6 cm) versus subjective assessment (white light) conditions (1.8 cm), P = .001. CONCLUSION: Use of NIFI/ICG was associated with low rates of UAS at 2-year follow-up in a cohort with high prevalence of prior radiation. NIFI/ICG was associated with longer lengths of ureter resection and ureteral perfusion assessment discordance compared to subjective surgeon assessment under white-light conditions.

The impact of intimate partner violence on PrEP adherence among U.S. Cisgender women at risk for HIV.

BACKGROUND: Cisgender women account for 1 in 5 new HIV infections in the United States, yet remain under-engaged in HIV prevention. Women experiencing violence face risk for HIV due to biological and behavioral mechanisms, and barriers to prevention, such as challenges to Pre-Exposure Prophylaxis for HIV Prevention (PrEP) adherence. In this analysis, we aim to characterize intimate partner violence (IPV) among cisgender heterosexual women enrolled in a PrEP demonstration project and assess the associations with PrEP adherence. METHODS: Adherence Enhancement Guided by Individualized Texting and Drug Levels (AEGiS) was a 48-week single-arm open-label study of PrEP adherence in HIV-negative cisgender women in Southern California (N = 130) offered daily tenofovir disoproxil fumarate/emtricitabine (TDF/FTC). From 6/2016 to 10/2018, women completed a survey reporting HIV risk behavior and experiences of any IPV (past 90-days) and IPV sub-types (past-year, lifetime) and biological testing for HIV/STIs at baseline, and concentrations of tenofovir-diphosphate (TFV-DP) in dried blood spots at weeks 4, 12, 24, 36, and 48. Outcomes were TFV-DP concentrations consistent with ≥ 4 or ≥ 6 doses/week at one or multiple visits. Multivariable logistic regression models were conducted to examine associations. RESULTS: Past-90-day IPV was reported by 34.4% of participants, and past-year and lifetime subtypes reported by 11.5-41.5%, and 21.5-52.3%, respectively. Women who engaged in sex work and Black women were significantly more likely to report IPV than others. Lifetime physical IPV was negatively associated with adherence at ≥ 4 doses/week at ≥ 3 of 5 visits, while other relationships with any IPV and IPV sub-types were variable. CONCLUSION: IPV is an indication for PrEP and important indicator of HIV risk; our findings suggest that physical IPV may also negatively impact long-term PrEP adherence.

The Media and Sexual Violence Among Adolescents: Findings from a Qualitative Study of Educators Across Vietnam.

Growing access to technology and media has presented new avenues of influence on youth attitudes and norms regarding sexuality and sexual violence, as well as new technological pathways through which to perpetrate sexual violence. The aim of this research was to understand contextual influences on and needs for scale-up of sexual violence prevention programming in the media-violence context of Vietnam. We conducted 45 interviews with high school teachers (n = 15), university lecturers (n = 15), and affiliates from youth-focused community service organizations (n = 15) from across Vietnam. Additionally, we conducted four sector-specific focus groups with a sub-sample of interview participants (k = 4, n = 22). Media and technology were brought up consistently in relation to sexual violence prevention and sexual health information. Key informants noted that, in Vietnam, generational differences in acceptability of sex and lack of comprehensive sexuality education intersect with new technological opportunities for exposure to sexual information and media. This creates a complex landscape that can promote sexual violence through priming processes, instigate mimicry of violent media, and presents new opportunities for the perpetration of sexual violence though technology. Development of comprehensive sexual education, including violence prevention education, is imperative, with consideration of age-specific needs for Vietnamese youth.

Providing Trauma-Informed Care During a Pandemic: How Health Care Workers at Ryan White-Funded Clinics in the Southeastern United States Responded to COVID-19 and Its Effects on Their Well-Being.

As HIV/AIDS health care workers (HCWs) deliver services during COVID-19 under difficult conditions, practicing trauma-informed care (TIC) may mitigate negative effects on mental health and well-being. This secondary qualitative analysis of a larger mixed methods study sought to understand the pandemic's impact on HCWs at Ryan White-funded clinics (RWCs) across the southeastern US and assess changes in prioritization of TIC. RWC administrators, providers, and staff were asked about impacts on clinic operations/culture, HCW well-being, institutional support for well-being, and prioritization of TIC. HCWs described strenuous work environments and decreased well-being (eg, increased stress, burnout, fear, and social isolation) due to COVID-19. RWCs initiated novel responses to disruptions of clinic operations and culture to encourage continuity in care and promote HCW well-being. Despite increased awareness of the need for TIC, prioritization remained variable. Implementing and institutionalizing trauma-informed practices could strengthen continuity in care and safeguard HCW well-being during public health emergencies.

Evaluation of an Opioid-free Pathway for Perineal Reconstructive Surgery: A 1-year Pilot Study.

OBJECTIVE: To evaluate the impact of a standardized perioperative pain management pathway on postoperative opioid prescribing practices following male perineal reconstructive surgery at our institution. METHODS: Patients undergoing perineal reconstructive surgery (urethroplasty, artificial urinary sphincter, urethral sling) by a single surgeon from July 2022 to June 2023 were prospectively followed. A standardized nonopioid pathway was implemented in the perioperative period. Intraoperative local anesthetic included liposomal bupivacaine mixed with 0.25% bupivacaine. Opioids are administered in the recovery room at the discretion of anesthesiology providers. As of July 2022, our standard practice does not include a postoperative opioid prescription unless pain is poorly controlled in the recovery area. Postoperative communication encounters and opioid prescriptions were tracked through the electronic health record (EHR) in order to assess the efficacy of an opioid-free pathway. RESULTS: Sixty-seven patients met the criteria during the study period, 64/67 performed in an outpatient setting. 6/67 (9%) patients were prescribed an opioid postoperatively; 4 related to post-surgical pain, and 2 related to chronic pain. No refills were prescribed. Of the 26 patients who received an opioid in the recovery area, 2 (7.6%) were prescribed an opioid at discharge. 15/67 (22%) patients had a communication encounter related to pain within 30 days, most commonly related to bladder spasm management. Only 2 of these encounters resulted in an electronic opioid prescription. CONCLUSION: An opioid-free pathway is appropriate for opioid naive men undergoing perineal reconstructive surgery. When necessary, electronic opioid prescribing should be employed following discharge for breakthrough pain.

The prevalence of impostor phenomenon and its association with burnout amongst urologists.

OBJECTIVES: To characterise the prevalence of impostor phenomenon (IP; tendency for high-achieving individuals to perceive themselves as fraudulent in their successes) amongst attending staff in urology, to identify variables that predict more severe impostorism, and to study the association of IP with burnout. SUBJECTS AND METHODS: A survey composed of the Clance Impostor Phenomenon Scale (CIPS), demographic information, practice details, and burnout levels was e-mailed to urologists via urological subspecialty societies. Survey results were analysed to identify associations between IP severity, survey respondent characteristics, and symptoms of professional burnout. This study was conducted in the United States of America. RESULTS: A total of 614 survey responses were received (response rate 11.0%). In all, 40% (n = 213) of responders reported CIPS scores qualifying as either 'frequent' or 'intense' impostorism (i.e., scores of 61-100). On multivariable analysis, female gender, fewer years in practice (i.e., 0-2 years), and lower academic rank were all independently associated with higher CIPS scores (adjusted P < 0.05). Regarding burnout, 46% of responders reported burnout symptoms. On multivariable analysis, increase in CIPS score was independently associated with higher odds of burnout (odds ratio 1.06, 95% confidence interval 1.04-1.07; P < 0.001). CONCLUSION: Impostor phenomenon is prevalent in the urological community and is experienced more severely in younger and female urologists. IP is also independently associated with burnout. Increased female representation may improve IP amongst our female colleagues. More work is needed to determine strategies that are effective in mitigating feelings of IP and professional burnout amongst urologists, particularly those earlier in their careers.

Analysis of British Columbia practice patterns in the management of female stress urinary incontinence with emphasis on mesh use.

INTRODUCTION: Female stress urinary incontinence (SUI) is common and has a profound impact on quality of life. Suburethral slings are the most common treatment for SUI in this population. These can be placed with synthetic mesh or autologous fascia. Mesh-related complications after midurethral sling procedures are documented in the literature but the risk of complications and reoperation is lower than the use of transvaginal mesh for pelvic organ prolapse repair. In this study, we sought to evaluate local practice patterns of management of female SUI with specific emphasis on mesh use. METHODS: A survey created by an expert panel was disseminated to respective provincial societies. RESULTS: Sixty-eight percent of respondents offer midurethral slings in their practice but only 60.6% of these respondents would offer surgical removal of the sling if there were complications, such as mesh erosion or pain. A large portion (39.4%) of respondents are performing transobturator slings as compared to retropubic midurethral slings (36.3%) and only 8.5% have removed the leg component associated with the transobturator sling in their practice. Furthermore, compared to most respondents offering midurethral slings (64.8%), only a minority of surgeons offer alternatives: 23.9% of respondents offer periurethral bulking agent injections, 15.5% offer pubovaginal slings, and 12.7% offer retropubic urethropexies. CONCLUSIONS: Our study supports that surgeons should continue to review surgical risks and alternative treatment options as part of the surgical consent process. As such, surgeons should be able to offer a variety of surgical approaches to manage female SUI.

Experiences of childhood, intimate partner, non-partner, and hate crime-related violence among a sample of people living with HIV in the epicenter of the U.S. HIV epidemic.

Introduction: Experiences of violence among people living with HIV (PLWH) are thought to be highly prevalent but remain inadequately captured. As a first step toward acceptable, trauma informed practices that improve engagement and retention in care for PLWH, we must acquire more comprehensive understanding of violence experiences. We examined experiences of various forms of lifetime violence: adverse childhood experiences (ACES), intimate partner violence (IPV), non-partner violence (NPV), and hate crimes among diverse sample of PLWH in Atlanta, Georgia. Methods: Cross sectional data collected from in- and out-of-care PLWH (N = 285) receiving care/support from Ryan White Clinics (RWCs), AIDS Service Organizations (ASOs), or large safety-net hospital, February 2021-December 2022. As part of larger study, participants completed interviewer-administered survey and reported on experiences of violence, both lifetime and past year. Participant characteristics and select HIV-related variables were collected to further describe the sample. Univariate and bivariate analyses assessed participant characteristics across types of violence. Results: High prevalence of past violence experiences across all types (ACES: 100%, IPV: 88.7%, NPV: 97.5%, lifetime hate crimes 93.2%). People assigned male at birth who identified as men experienced more violence than women, with exception of non-partner forced sex. Participants identifying as gay men were more likely to have experienced violence. Conclusion: Among our sample of PLWH at the epicenter of the United States HIV epidemic, histories of interpersonal and community violence are common. Findings emphasize need for RWCs, ASOs, and hospital systems to be universally trained in trauma-informed approaches and have integrated onsite mental health and social support services.

Plant macrofossil data for 48-0 ka in the USGS North American Packrat Midden Database, version 5.0.

Plant macrofossils from packrat (Neotoma spp.) middens provide direct evidence of past vegetation changes in arid regions of North America. Here we describe the newest version (version 5.0) of the U.S. Geological Survey (USGS) North American Packrat Midden Database. The database contains published and contributed data from 3,331 midden samples collected in southwest Canada, the western United States, and northern Mexico, with samples ranging in age from 48 ka to the present. The database includes original midden-sample macrofossil counts and relative-abundance data along with a standardized relative-abundance scheme that makes it easier to compare macrofossil data across midden-sample sites. In addition to the midden-sample data, this version of the midden database includes calibrated radiocarbon (14C) ages for the midden samples and plant functional type (PFT) assignments for the midden taxa. We also provide World Wildlife Fund ecoregion assignments and climate and bioclimate data for each midden-sample site location. The data are provided in tabular (.xlsx), comma-separated values (.csv), and relational database (.mdb) files.

Surgical Management of Endometriosis Involving the Bladder and Ureter.

BACKGROUND: Endometriosis is a chronic, debilitating condition affecting up to 10% of reproductive-age women. Urinary tract endometriosis is found in 1%-6% of women diagnosed with pelvic endometriosis, with the most common sites being the bladder (70%-85%), ureter (9%-23%), and kidney (4%). Patients typically present with symptoms such as lower abdominal pain, dysuria, and urgency. Unfortunately, urinary tract endometriosis is often asymptomatic, potentially leading to silent obstructive uropathy and kidney failure. OBJECTIVE: To demonstrate a step-by-step approach for the surgical management of urinary tract endometriosis using conventional laparoscopy for partial cystectomy and robotic-assisted laparoscopy for ureteroneocystostomy. MATERIAL AND METHOD: Surgical video of 2 cases managed in an academic tertiary referral center for endometriosis. The first case was a 38-year-old Gravida 3, Para 3 with a history of hysterectomy who had an MRI which revealed a T2 hypointense bladder nodule consistent with endometriosis. Patient had significant urinary urgency, dysuria, and suprapubpic pain that improved but did not disappear after starting oral progestin therapy (5 mg of norethindrone). A cystoscopy was first performed to confirm MRI findings of bladder lesion and to delineate borders and depth of invasion. The second case was a 35-year-old nulliparous woman with chronic pelvic pain and primary infertility. The patient had a history of stage IV endometriosis with deep endometriosis into the bowel and extrinsic encasement of the ureters causing subsequent hydronephrosis requiring bilateral ureteral stents. She had continued daily pelvic pain despite of being on oral contraceptives for medical management of endometriosis. She subsequently underwent bilateral percutaneous nephrostomy tube placement to allow for ureteral rest prior to surgery. RESULTS: In the first case, conventional laparoscopy was utilized to perform bilateral ureterolysis, bladder mobilization, partial cystectomy for complete excision of the lesion, and 2-layered bladder closure. Use of indigo carmine assisted with ureteral orifice identification. In the second case, a cystoscopy was performed with injection of Indocyanine green to assist with ureteral identification. After ureterolysis, distal ureteric obstruction due to extensive disease was confirmed on laparoscopy and ureteroscopy. Bilateral ureteroneocystostomy with placement of Double-J ureteral stents was performed using a robotic-assisted approach. Each patient had an indwelling Foley catheter for bladder decompression during recovery. Pathology in both cases revealed endometriosis. Both patients had an uneventful postoperative course. A postoperative retrograde cystogram confirmed adequate repair prior to removal of each Foley catheter. Patient 2 had uncomplicated office stent removal 6 weeks postoperatively and had a normal renal ultrasound with no hydronephrosis 6 months postoperatively. CONCLUSION: Endometriosis is an increasingly common condition. It is important for gynecological surgeons to have the proper understanding of anatomy, surgical technique, and multidisciplinary care needed with urology for safe and complete excision of bladder and ureter endometriosis.
