RESUMEN
INTRODUCTION: Performing surgical procedures is a recognized source of stress for surgeons. Vocational stress is an important contributor to performance, patient care, and burnout with dispositional and environmental factors contributing. Accurately assessing surgeon stress is critical to measuring effectiveness of stress reduction programs. The primary aim was to identify differences between surgeons' self-reported anticipated stress and anxiety prior to gynecological surgery, compared with their recollection of experienced stress and anxiety during surgery. Secondary aims assessed any differences by level of training, surgical type, and surgeon role. MATERIAL AND METHODS: Attending and resident gynecologists performing routine elective surgeries completed a visual analog scale (VAS) assessing perceived stress and the State-Trait Anxiety Inventory (STAI) prior to and immediately after completing 161 elective surgeries including total laparoscopic hysterectomy, laparoscopic excision of moderate-severe endometriosis, or hysteroscopic myomectomy. RESULTS: Eight attending gynecologists and nine residents participated. Residents commenced as primary surgeon in 62/90 (69%) procedures. Stress experienced during surgery was greater than anticipated in 92/161 (57%) surgery episodes (mean VAS increase: 3.9; 95% CI: 1.1-6.8, p = 0.009). State anxiety was greater than anticipated in 99/161 (62%) episodes (mean state anxiety increase: 4.4; 95% CI: 3.0-5.8, p < 0.001). Greater preprocedural anticipatory stress and anxiety was observed in residents vs. attending gynecologists (VAS 51.9 vs. 22.8, p < 0.001; state anxiety 38.3 vs. 28.1, p < 0.001) and in primary vs. assistant surgeons (VAS 47.2 vs. 29.9, p < 0.001; state anxiety 36.9 vs. 28.3, p < 0.001). Intraoperative stress and anxiety were greater in primary surgeons (VAS 50.4 vs. 30.5, p < 0.001; anxiety 41.3 vs. 32.5, p < 0.001) and residents (VAS 43.4 vs. 31.7, p < 0.001; anxiety 53.5 vs. 33.7, p < 0.001) compared with assistants and attending gynecologists. Perceived stress and anxiety were positively correlated at both timepoints (r = 0.68, p < 0.001; r = 0.82, p < 0.001). CONCLUSIONS: When asked to reflect on stress experienced during surgery, our data show that stress during surgery is greater than anticipated for many surgical episodes. Self-reported stress symptoms commence prior to surgery and are more commonly reported by surgeons operating as primary surgeon and by those in training. Future research should focus on determinants of presurgical stress and examine when stressors become inhibitory to performance.

STUDY OBJECTIVE: To assess long-term urinary function for women having laparoscopic surgery for endometriosis. DESIGN: Institutional Review Board-approved nested cohort study within a larger randomized controlled trial assessing urinary function following any benign laparoscopy for gynecological presentations. SETTING: Two tertiary-level university-affiliated hospitals. PATIENTS: Women with histologically confirmed endometriosis within the randomized controlled trial between April 2012 and November 2019, where baseline urinary function was determined. INTERVENTIONS: Women with histologically confirmed endometriosis were contacted between February and October 2020, and urinary function was re-assessed. MEASUREMENTS AND MAIN RESULTS: Urinary function was assessed using validated questionnaires across the domains of filling, voiding, incontinence, and quality of life determined distant from surgery. Higher scores correlated with a greater severity of symptoms. From 518/711 (72.9%) women with histologically confirmed endometriosis, 289/518 (55.8%) consented to the nested study. At a mean of 50 months (range 12-103 months) post-operatively, 35 participants (12.1%) had sought treatment for bladder symptoms, and 81 participants (28.0%) reported at least one urinary tract infection since their index surgery. There was a significant worsening of symptoms for filling, voiding, incontinence, and quality of life pre-operative to post-operatively (2.27 vs 3.32, 0.93 vs 2.02, 1.06 vs 2.32, 0.83 vs 2.13 respectively, p <.001). There was no statistically significant difference in urinary questionnaire scores in participants with and without uterovesical endometriosis. There was no statistically significant difference in any parameter when comparing any revised American Society of Reproductive Medicine (rASM) stage of endometriosis. Participants who had post-operative urinary retention reported a higher mean voiding score than those who did not (3.24 vs 1.94, p = .017), while participants with post-operative urinary tract infection reported a higher mean frequency score than those who did not (5.17 vs 3.24, p = .016). CONCLUSION: This study suggests a decline in urinary function over time following laparoscopic surgery for endometriosis that is not dependent on the severity or location of the disease.

OBJECTIVE: No consensus currently exists regarding patient-reported outcome measure (PROM) instruments. This structured review was conducted to identify the PROMs used by randomized controlled trials (RCTs) that evaluated surgical treatment in patients with endometriosis. DATA SOURCES: Two parallel searches were conducted by a medical librarian using Ovid MEDLINE, Ovid Embase, and Cochrane Library for RCTs published from 2000 to July 2022. One search focused on studies reporting quality of life (QoL), and the second search focused on studies reporting pain and sexual, bowel, and bladder function. METHOD OF STUDY SELECTION: During the title and abstract screening and reference check, 600 results were identified on PROMs relating to QoL and 465 studies on PROMs relating to pain and sexual, bowel, and/or bladder function and an evaluation of 17 and 12 studies conducted, respectively. The inclusion criteria involved selecting RCTs that focused on surgical intervention and assessing QoL, pain, and sexual, bowel, and/or bladder function using PROMs. TABULATION, INTEGRATION, AND RESULTS: Covidence software was used to organize and identify duplicate articles through screening. We developed a data extraction form to collect key information about each included study, as well as the pertinent PROMs used in the study. Assessment of the risk of bias of each study was also performed. A total of 19 studies were identified involving 2089 participants and a total of 16 PROMs used across the studies; 9 of 19 studies (47%) were rated as having a low risk of bias. There were no high-risk studies identified in this review. CONCLUSION: This study identified a large number of RCTs in surgical treatment of endometriosis that used various PROMs to assess QoL, pain, and bladder, bowel, and sexual function. The PROMs used by high-quality RCTs for QoL include Endometriosis Health Profile-30, Endometriosis Health Profile-5, Short-Form 36, Short-Form 12, and EQ-5D; for bowel-related symptoms Knowles-Eccersley-Scott-Symptom Questionnaire, Gastrointestinal Quality of Life Index, and Cleveland Clinic Fecal Incontinence Severity Scoring System/Wexner; for bladder-related function Bristol Female Lower Urinary Tract Symptoms, International Prostate Symptom Score, Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire, and Urinary Symptom Profile; and finally for sexual function Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire and Sexual Activity Questionnaire. Unlike other domains, only one tool (visual analog scale) was the dominant PROM used for the assessment of pain. In addition, the use of more than one PROM in each study to assess different aspects of patient's health and pain symptoms did not become prevalent until after 2015.

BACKGROUND: Microvascular scarring compromises the functionality of the endometrium, and vascular flow at the junctional zone (JZ) may be the key to understanding poor reproductive outcomes in women with Asherman syndrome (AS). AIMS: To investigate whether vascular perfusion of the uterus, measured by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is impaired in women with intrauterine adhesions (IUA) and AS. MATERIALS AND METHODS: A prospective observational cohort pilot study of 23 women with IUA treated with hysteroscopic synecholysis and a control group of two patients with cervix cancer were subject to DCE-MRI with gadolinium to assess uterine vascularity. Twelve regions of interest (ROIs) were allocated on the DCE-MRI image incorporating the JZ, with control ROI placed at the psoas muscle. Individual ROIs were compared to the mean total perfusion (TP) in the same uterus. Pre- and post-operative perfusion analyses were performed on five women. Receiver operator curves (ROC) were used to analyse MRI as a predictor of IUA. RESULTS: There was no significant difference in perfusion; a trend toward reduced perfusion was observed in women with IUA compared to the controls. The ROC was predictive of higher-grade and inoperable IUA. CONCLUSIONS: Reduced perfusion on DCE-MRI as assessed by ROC predicted higher-stage AS. The results of this study support further investigation of DCE-MRI as a prognostic tool for AS prior to surgical intervention to assist in providing prognostic guidance for women suffering from AS.

People with endometriosis use cannabis to manage their symptoms. This study aimed to identify costs, modes of administration, product composition, and self-reported effectiveness for those accessing medicinal cannabis in Australia. There were 192 survey responses analysed. Most (63.5%) used a 'cannabis clinic' doctor, incurring an initial consultation cost of $100-$200+ (10.2% Medicare bulk-billed) and median cannabinoid medicine costs of $300AUD per month. Cost was a major barrier to access, necessitating reducing dosage (76.1%) and/or consuming illicit cannabis (42.9%), despite a prescription. Most (77%) medical consumers used two or more cannabis products, with delta-9-tetrahydrocannabinol predominant oil and flower products most frequently prescribed.

A reliable non-invasive biomarker for endometriosis is highly likely in the coming years. In the lead-up to this, clinicians need to be aware of commercially available tests as they become accessible, be aware of the level of evidence to support them and be prepared to counsel and manage patients who present with the results of such tests. One such test gaining popularity in Europe was developed using a machine-based learning algorithm to analyse thousands of microRNAs based on a 200-patient cohort with suspected endometriosis in France. We explore the background science for this commercially available test; outline the questions that remain to be answered; and caution against its use outside of a research setting.

BACKGROUND: Laparoscopic reverse submucosal dissection (LRSD) is a standardised surgical technique for removal of rectosigmoid endometriosis which optimises the anatomical dissection plane for excision of endometriotic nodules. AIM: This cohort study assesses the outcomes of the first cohort of women treated by LRSD, for deeply infiltrating rectosigmoid endometriosis. MATERIALS AND METHODS: Primary outcomes assessed were complication rate as defined by the Clavien-Dindo system, and completion of the planned LRSD. Secondary outcomes include mucosal breach, specimen margin involvement, length of hospital admission, and a comparison of pre-operative and post-operative pain, bowel function and quality of life surveys. These included the Endometriosis Health Profile Questionnaire (EHP-30), the Knowles-Eccersley-Scott Symptom Questionnaire (KESS) and the Wexner scale. RESULTS: Of 19 patients treated, one required a segmental resection. The median length of hospital admission was two days (range 1-5) and no post-operative complications occurred. Median pain visual analogue scales (scale 0-10) were higher prior to surgery (dysmenorrhoea 9.0, dyspareunia 7.5, dyschezia 9.0, pelvic pain 6.0) compared to post-surgical median scores (dysmenorrhoea 5.0, dyspareunia 4.0, dyschezia 2.0, pelvic pain 4.0) at a median of six months (range 4-32). Quality of life studies suggested improvement following surgery with pre-operative median EHP-30 and KESS scores (EHP-30: 85 (5-106), KESS score 9 (0-20)) higher than post-operative scores (EHP-30: 48.5 (0-80), KESS score: 3 (0-19)). CONCLUSION: This series highlights the feasibility of LRSD with low associated morbidity as a progression of partial thickness discoid excision (rectal shaving) for the treatment of rectosigmoid deep infiltrating endometriosis.

AIM: Uterus transplantation (UTx) is an emerging treatment option for women with uterine factor infertility (UFI) or the absence of a functional uterus. This is the study protocol for the first human UTx clinical trial in Australia. MATERIALS AND METHODS: This protocol outlines the approved training program used to plan, diagnose, screen, and treat patients who may be eligible for UTx using living and deceased donors. This multi-site clinical research study includes three tertiary hospital sites within New South Wales (NSW), Australia - Prince of Wales, Royal Hospital for Women and Westmead Hospitals. Our UTx protocol is based on that used by our collaborative partner, the inaugural UTx team in Gothenburg, Sweden. The Swedish UTx team provides ongoing preceptorship for the Australian UTx team. Ethics approval for six UTx procedures using living or deceased donors (Western Sydney Local Health District Human Research Ethics Committee: 2019/ETH138038) was granted in 2020. RESULTS: Results from surgeries and live births will be published. Data will be prospectively entered into the registry of the International Society of Uterus Transplantation (ISUTx), a sub-section of The Transplantation Society (TTS). TRIAL ID: ACTRN12622000917730. DISCUSSION: A multidisciplinary research team has been formed between three tertiary hospitals in Sydney - The Royal Hospital for Women, Prince of Wales and Westmead Hospitals; and with the Swedish UTx, University of Gothenburg. The Swedish team pioneered animal and human UTx studies since 1998, including publishing the first live birth after UTx. (1) This Australian trial commenced in January 2023. CONCLUSION: Uterus transplantation gives women with UFI the opportunity to be gestational and genetic mothers. It is a complex procedure for both the donor and recipient, with medical and surgical risks. An extensive multidisciplinary approach is required to optimise patient safety and graft outcomes. This protocol outlines our Australian UTx team strategy for screening, recruitment, surgical approach, and clinical management of UTx recipients and donors.

BACKGROUND: Postmenopausal vaginal symptoms affect over 60% of women and may substantially impact a woman's quality of life. Since 2012, fractional CO2 laser has been suggested as a treatment for this indication. Structural assessment of vaginal epithelium using microscopic biopsy examination has been used as a primary outcome measure and surrogate determinant of success of vaginal laser in previous clinical studies. OBJECTIVE: This study aimed to report the effects of laser compared with sham treatment on human vaginal epithelium from postmenopausal women using microscopic examination of tissue biopsies. STUDY DESIGN: This single-center double-blind, sham-controlled randomized controlled trial was performed in a tertiary hospital in Sydney, Australia. A total of 49 postmenopausal women who were symptomatic of at least 1 vaginal symptom (vaginal dryness, burning, itching; dyspareunia; or dryness) were randomized to either laser or sham treatment. For this nested histologic study, participants had a pre- and post-treatment vaginal wall biopsy collected. Biopsy samples were analyzed by 3 independent specialist gynecologic pathologists and categorized as Type 1 (well-estrogenized), 2 (poorly estrogenized), or 3 (combination) mucosae. Other outcomes assessed included symptom severity (visual analog scale for symptoms including most bothersome symptom, and Vulvovaginal Symptom Questionnaire) and Vaginal Health Index. Prespecified secondary analyses of data were performed. Categorical data were analyzed using the Pearson chi-square test (or Fisher exact test if <5 in any category) or related-samples McNemar test for paired nonparametric data. Nonparametric, continuous variables were assessed using Wilcoxon signed-rank test or Mann-Whitney U test, and parametric variables with t test or 1-way analysis of variance as appropriate. All analyses were performed using SPSS software version 26.0 (IBM Corp, Armonk, NY). RESULTS: There was no significant difference in microscopic features of vaginal epithelium following laser or sham treatment (P=.20). Further subgroup analyses of age, menopause type, duration of reproductive life, time since menopause and BMI, still demonstrated no significant difference between laser and sham groups in histological category of vaginal epithelium. Microscopic features at pre-treatment vaginal biopsy were Type 1 in 27% (13/49). There was no significant difference in VAS score for overall vaginal symptom between those classified as Type 1 vs. Type 2/3 (VAS score overall: Type 1 vs. Type 2/3, (48.1 [95% CI 27.0, 69.2] vs. 61.5 [95% CI 49.8, 73.3]; P=.166). CONCLUSION: Data from this double-blind, sham-controlled randomized controlled trial demonstrate that fractional CO2 laser and sham treatment have a comparable histologic effect on vaginal tissue that is not significantly different. Fractional CO2 laser is not significantly different from sham treatment and should not be recommended for clinical use for postmenopausal vaginal symptoms.

OBJECTIVE: To compare rates of urinary retention and postoperative urinary tract infection between women with immediate versus women with delayed removal of indwelling catheter following benign non-hysterectomy gynaecological laparoscopic surgery. DESIGN: This randomised clinical trial was conducted between February 2012 and December 2019, with follow-up to 6 weeks. SETTING: Two university-affiliated teaching hospitals in Sydney, Australia. POPULATION: Study participants were 693 women aged 18 years or over, undergoing non-hysterectomy laparoscopy for benign gynaecological conditions, excluding pelvic floor or concomitant bowel surgery. METHODS: Three hundred and fifty-five participants were randomised to immediate removal of urinary catheter and 338 participants were randomised to delayed removal of urinary catheter. MAIN OUTCOME MEASURES: The co-primary outcomes were urinary retention and urinary tract infection. Secondary outcomes included hospital readmission, analgesia requirements, duration of hospitalisation and validated bladder function questionnaires. RESULTS: Urinary retention was higher after immediate compared with delayed removal of the urinary catheter (8.2% vs 4.2%, RR 1.8, 95% CI 1.0-3.0, p = 0.04). Although urinary tract infection was 7.2% following delayed removal of the urinary catheter and 4.7% following immediate removal of the urinary catheter, the difference was not statistically significant (RR 0.7, 95% CI 0.3-1.2, p = 0.2). CONCLUSIONS: There is an increased risk of urinary retention with the immediate compared with the delayed removal of the urinary catheter following benign non-hysterectomy gynaecological laparoscopic surgery. The difference in urinary tract infection was not significant. There is 1/12 risk of re-catheterisation after immediate urinary catheter removal. It is important to ensure that patients report normal voiding and emptying prior to discharge, to reduce the need for readmission for the management of urinary retention.

Rationale: Cigarette smoke exposure is associated with an increased risk of developing acute respiratory distress syndrome (ARDS) in trauma, transfusion, and nonpulmonary sepsis. It is unknown whether this relationship exists in the general sepsis population. Furthermore, it is unknown if patients with ARDS have differences in underlying biology based on smoking status. Objectives: To assess the relationship between cigarette smoke exposure and ARDS in sepsis and identify tobacco-related biomarkers of lung injury. Methods: We studied a prospective cohort of 592 patients with sepsis from 2009 to 2017. Plasma cotinine and urine NNAL [urine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol] were measured to categorize smoking status. Plasma biomarkers of inflammation and lung injury were measured, including in a smaller cohort of trauma patients with ARDS to increase generalizability. Measurements and Main Results: Passive and active smoking were associated with increased odds of developing ARDS in patients with sepsis. Among patients with sepsis and ARDS, active cigarette smokers were younger and had lower severity of illness than nonsmokers. Patients with ARDS with cigarette smoke exposure had lower plasma levels of IL-8 (P = 0.01) and sTNFR-1 (soluble tumor necrosis factor 1; P = 0.01) compared with those without exposure. Similar biomarker patterns were observed in blunt trauma patients with ARDS. Conclusions: Passive and active smoking are associated with an increased risk of developing ARDS in patients with pulmonary and nonpulmonary sepsis. Among patients with ARDS, those with cigarette smoke exposure have less systemic inflammation, while active smokers also have lower severity of illness compared with nonsmokers, suggesting that smoking contributes to biological heterogeneity in ARDS.

STUDY OBJECTIVE: To assess changes in biological measures of acute stress in surgeons during surgery in real-world settings DESIGN: A prospective cohort study. SETTING: A tertiary teaching hospital. PATIENTS: 8 consultant and 9 training gynecologists. INTERVENTION: A total of, 161 elective gynecologic surgeries of 3 procedures: laparoscopic hysterectomy, laparoscopic excision of endometriosis, or hysteroscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: Changes in surgeons' biological measures of acute stress while undertaking elective surgery. Salivary cortisol, mean and maximum heart rate (HR), and indices of the HR variability were recorded before and during surgery. From baseline to during surgery over the cohort, salivary cortisol decreased from 4.1 nmol/L to 3.6 nmol/L (p = .03), maximum HR increased from 101.8 beats per min (bpm) to 106.5 bpm (p <.01), root mean square of standard deviation decreased from 51.1 ms to 39.0 ms (p <.01), and standard deviation of beat-to-beat variability decreased from 73.7 to 59.8 ms (p <.01). Analysis of individual changes in stress by participant-surgery event by paired data graphs reveal inconsistent direction of change in all measures of biological stress despite stratification by surgical experience, role in surgery, level of training, or type of surgery performed. CONCLUSION: This study measured biometric stress changes at both a group and individual level in real-world, live surgical settings. Individual changes have not previously been reported and the variable direction of stress change by participant-surgery episode identified in this study demonstrates a problematic interpretation of mean cohort findings previously reported. Results from this study suggest that either live surgery with tight environment control or surgical simulation studies may identify what, if any, biological measures of stress can predict acute stress reactions during surgery.
RESUMEN
OBJECTIVE: To assess the efficacy and safety of mechanical bowel preparation (MBP) before benign laparoscopic or vaginal gynecologic surgeries. DATA SOURCES: Database searches of MEDLINE (PubMed), Embase (OVID), Cochrane Central Register of Controlled Trials, and Web of Sciences and citations and reference lists published up to December 2021. METHODS OF STUDY SELECTION: Randomized clinical trials in any language comparing MBP with no preparation were included. Two reviewers independently screened 925 records and extracted data from 12 selected articles and assessed the risk of bias with the Cochrane risk-of-bias tool for randomized trials tool. A random-effects model was used for the analysis. Surgeon findings (surgical field view, quality of bowel handling and bowel preparation), operative outcomes (blood loss, operative time, length of stay, surgical site infection), and patient's preoperative symptoms and satisfaction were collected. TABULATION, INTEGRATION, AND RESULTS: Thirteen studies (1715 patients) assessing oral and rectal preparations before laparoscopic and vaginal gynecologic surgeries were included. No significant differences were observed with or without MBP on surgical field view (primary outcome, risk ratio [RR] 1.01, 95% confidence interval [CI] 0.97-1.05, p = .66, I2 = 0%), bowel handling (RR 1.01, 95% CI 0.95-1.08, p = .78, I2 = 67%), or bowel preparation. In addition, there were no statistically significant differences in perioperative findings. MBP was associated with increased pain (mean difference [MD] 11.62[2.80-20.44], I2 = 76, p = .01), weakness (MD 10.73[0.60-20.87], I2 = 94, p = .04), hunger (MD 17.52 [8.04-27.00], I2 = 83, p = .0003), insomnia (MD 10.13[0.57-19.68], I2 = 82, p = .04), and lower satisfaction (RR 0.68, 95% CI 0.53-0.87, I2 = 76%, p = .002) compared with controls. CONCLUSIONS: MBP has not been associated with improved surgical field view, bowel handling, or operative outcome. However, in view of the adverse effects induced, its routine use before benign gynecologic surgeries should be abandoned.

BACKGROUND: Uterus transplantation is an emerging treatment option for uterine factor infertility. Most uterus transplantation research programs use living donors, although this comes with considerable surgical and psychological risks and not all women desiring uterus transplantation will have an available living donor. A deceased donor program eliminates donor risks; however, the availability of deceased uterus donors is currently unknown in Australia. AIMS: To establish the feasibility of a deceased donor uterus transplantation program in Australia and consider expanded inclusion criteria for this model. MATERIALS AND METHODS: A retrospective review of the New South Wales (NSW) Organ and Tissue Donation Service database was undertaken to identify potential deceased uterus donors, with comparison to the broad deceased donor inclusion criteria from three international uterus transplantation trials including female, brain-dead, multi-organ donation, no major abdominal surgery, and <60 years of age. RESULTS: Between January 1, 2018, and December 31, 2022, 648 deceased donors were available in NSW. Of these, 43% (279/648) were female and 67% of the women (187/279) were also multi-organ donors. When the brain-dead donor-only and age criteria (<60 years) were applied, a total of 107 deceased donors met the available criteria for uterus transplantation, with an average of 21 deceased donors per year in NSW. CONCLUSIONS: There appears to be adequate deceased donor organ availability to establish a deceased uterus transplantation program in NSW, Australia. Should interest in uterus transplantation increase, including criteria such as older and nulliparous donors could increase organ availability for a uterus transplantation program.

In Australia, endometriosis affects one in nine women and those assigned female at birth. Although endometriosis is more common than conditions such as diabetes, research funding for endometriosis research has historically been low in comparison. The National Action Plan for Endometriosis is an Australian Federal Government initiative designed to redress this imbalance, with a focus on research funding. Identification of research priorities, and subsequent funding allocation that is determined by consumer input is vital. An online survey focusing on Australia and New Zealand found that the highest general priorities were the treatment and management of endometriosis and its cause(s).

AIMS: The aim is to report the results of Australia's first uterus transplantation (UTx). METHODS: Following long-standing collaboration between the Swedish and Australian teams, Human Research Ethics approval was obtained to perform six UTx procedures in a collaborative multi-site research study (Western Sydney Local District Health 2019/ETH13038), including Royal Hospital for Women, Prince of Wales Hospital, and Westmead Hospital in New Souh Wales. Surgeries were approved in both the live donor (LD) and deceased donor models in collaboration with the inaugural Swedish UTx team. RESULTS: This is the first UTx procedure to occur in Australia, involving a mother donating her uterus to her daughter. The total operative time for the donor was 9 h 54 min. Concurrently, recipient surgery was synchronised to minimise graft ischaemic time, and the total operative time for the recipient was 6 h 12 min. Surgery was by laparotomy in the LD and recipient. The total warm ischaemic time of the graft was 1 h 53 min, and the cold ischaemic time was 2 h 17 min (total ischaemic time 4 h 10 min). The patient's first menstruation occurred 33 days after the UTx procedure. CONCLUSION: Twenty-five years of Swedish and Australian collaboration has led to Australia's first successfully performed UTx surgery at The Royal Hospital for Women, Sydney, Australia.

RATIONALE: Using latent class analysis (LCA), two subphenotypes of acute respiratory distress syndrome (ARDS) have consistently been identified in five randomised controlled trials (RCTs), with distinct biological characteristics, divergent outcomes and differential treatment responses to randomised interventions. Their existence in unselected populations of ARDS remains unknown. We sought to identify subphenotypes in observational cohorts of ARDS using LCA. METHODS: LCA was independently applied to patients with ARDS from two prospective observational cohorts of patients admitted to the intensive care unit, derived from the Validating Acute Lung Injury markers for Diagnosis (VALID) (n=624) and Early Assessment of Renal and Lung Injury (EARLI) (n=335) studies. Clinical and biological data were used as class-defining variables. To test for concordance with prior ARDS subphenotypes, the performance metrics of parsimonious classifier models (interleukin 8, bicarbonate, protein C and vasopressor-use), previously developed in RCTs, were evaluated in EARLI and VALID with LCA-derived subphenotypes as the gold-standard. RESULTS: A 2-class model best fit the population in VALID (p=0.0010) and in EARLI (p<0.0001). Class 2 comprised 27% and 37% of the populations in VALID and EARLI, respectively. Consistent with the previously described 'hyperinflammatory' subphenotype, Class 2 was characterised by higher proinflammatory biomarkers, acidosis and increased shock and worse clinical outcomes. The similarities between these and prior RCT-derived subphenotypes were further substantiated by the performance of the parsimonious classifier models in both cohorts (area under the curves 0.92-0.94). The hyperinflammatory subphenotype was associated with increased prevalence of chronic liver disease and neutropenia and reduced incidence of chronic obstructive pulmonary disease. Measurement of novel biomarkers showed significantly higher levels of matrix metalloproteinase-8 and markers of endothelial injury in the hyperinflammatory subphenotype, whereas, matrix metalloproteinase-9 was significantly lower. CONCLUSION: Previously described subphenotypes are generalisable to unselected populations of non-trauma ARDS.

RESEARCH QUESTION: Do women with laparoscopically confirmed endometriosis have higher plasma concentrations of circulating cell-free DNA (cirDNA) than those without endometriosis? DESIGN: Prospective study of women aged 18-45 years undergoing benign gynaecological laparoscopy at two tertiary hospitals. Venous blood was collected immediately before surgery, and women were allocated to the endometriosis or control groups based on surgical findings. Total plasma cirDNA and cirDNA integrity were measured by quantitative polymerase chain reaction (qPCR) targeting short (115 bases) and long (247 bases) ALU segments. Endometrial-derived cirDNA was measured by qPCR of bisulfite-treated cirDNA using primers selective for a FAM101A sequence uniquely unmethylated in endometrial tissue. Five cirDNA parameters were compared between the control and endometriosis cohorts: total cirDNA concentration, long-stranded cirDNA concentration, integrity ratio, endometrial cirDNA concentration and endometrial cirDNA proportion. RESULTS: Twenty-eight endometriosis and 15 control samples were included. Women with and without endometriosis had cirDNA concentrations of 2.24 ± 0.89 ng/ml and 2.56 ± 0.92 ng/ml, respectively. Analysis by phenotype of endometriosis revealed a significantly higher endometrial cirDNA concentration in women with superficial disease (nâ¯=â¯10) compared with deep endometriosis (nâ¯=â¯18) (mean difference 0.14 ng/ml; 95% CI 0.15 to 0.26; Pâ¯=â¯0.025), but not with controls. CONCLUSIONS: No significant differences were found in any of the cirDNA parameters between women with and without endometriosis. The low statistical power and heterogenous pelvic pathology in the control group render it difficult to determine whether the negative results reflect a true lack of increase in cirDNA in endometriosis.

AIMS: The objective of this study was to provide follow-up data on four-dimensional ultrasound (4DUS) morphometry for women having botulinum toxin type A (BoNT-A) treatment of pelvic floor tension myalgia (PFTM). MATERIALS AND METHODS: A prospective cohort study was performed from October 2013 to June 2018, recruiting women scheduled for BoNT-A injection in the pelvic floor musculature. Translabial 4DUS, vaginal pressure assessment by manometry and pain visual analog scales (VAS) were performed on all women before injection and again at 4, 12, and 26 weeks. The BoNT-A injection was performed under 4DUS guidance. RESULTS: Twenty-nine women had 44 injections over the course of the study. Although improvements were seen in VAS scores for dysmenorrhea, nonmenstrual pelvic pain, and dyspareunia, there were no significant differences in ultrasound biometry at either rest, Valsalva, or on contraction when comparing postinjection measurements at 4, 12, and 26 weeks with pre-injection baseline. Similarly, vaginal pressure readings at rest demonstrated a significant improvement throughout the 4, 12, and 26 week follow-up, with a reduction in maximal contraction at 4 and 12 but not 26 weeks. CONCLUSIONS: This study demonstrates that 4DUS biometry of the pelvic floor does not correlate with clinical pain and vaginal pressure outcomes for BoNT-A injection in the context of PFTM.

INTRODUCTION AND HYPOTHESIS: Myofascial pain arising from pelvic floor muscles occurs in women with vaginismus, interstitial cystitis and endometriosis but is often overlooked. The aim is to examine alternative diagnostic tests to detect pelvic floor myofascial pain compared with standardized vaginal palpation of pelvic floor muscles as the reference test. METHODS: A systematic review was prospectively conducted (PROSPERO-CRD42020183092) according to PRISMA guidelines. Databases searched included Ovid Medline 1946-, Embase 1957-, Scopus 1960-, Cochrane Combined, Clinical trials, Google Scholar (top 200 articles), Web of Science, TRIP, BIOSIS, DARE, CINHAL, EmCare, PEDro, ProQuest and EBSCOhost up to July 2020. Articles were independently screened by two authors and assessed for bias using QUASDAS-2 tool. RESULTS: A total of 26,778 articles were screened and 177 were selected for full text review, of which 5 were selected for final analysis. Five studies included 9694 participants of which 1628 had pelvic floor myofascial pain. Only one study reported data to calculate sensitivities and specificities of the index test, which utilized a score of > 40 on the Central Sensitization Inventory to detect women with pelvic floor myofascial pain and revealed a sensitivity of 34.8% and a specificity of 84.9% compared to the reference test. CONCLUSIONS: This systematic review did not reveal any diagnostic test superior to the pre-defined reference test. There is a lack of consensus on the definition of pelvic floor myofascial pain and a lack of a validated diagnostic criteria which must be addressed to progress with meaningful research in this field.
