ABSTRACT
INTRODUCTION AND HYPOTHESIS: Our aim was to compare the mid-term results of native tissue, biological xenograft and polypropylene mesh surgery for women with vaginal wall prolapse. METHODS: A total of 1348 women undergoing primary transvaginal repair of an anterior and/or posterior prolapse were recruited between January 2010 and August 2013 from 35 UK centres. They were randomised by remote allocation to native tissue surgery, biological xenograft or polypropylene mesh. We performed both 4- and 6-year follow-up using validated patient-reported outcome measures. RESULTS: At 4 and 6 years post-operation, there was no clinically important difference in Pelvic Organ Prolapse Symptom Score for any of the treatments. Using a strict composite outcome to assess functional cure at 6 years, we found no difference in cure among the three types of surgery. Half the women were cured at 6 years but only 10.3 to 12% of women had undergone further surgery for prolapse. However, 8.4% of women in the mesh group had undergone further surgery for mesh complications. There was no difference in the incidence of chronic pain or dyspareunia between groups. CONCLUSIONS: At the mid-term outcome of 6 years, there is no benefit from augmenting primary prolapse repairs with polypropylene mesh inlays or biological xenografts. There was no evidence that polypropylene mesh inlays caused greater pain or dyspareunia than native tissue repairs.

Acorn worms, also known as enteropneust (literally, 'gut-breathing') hemichordates, are marine invertebrates that share features with echinoderms and chordates. Together, these three phyla comprise the deuterostomes. Here we report the draft genome sequences of two acorn worms, Saccoglossus kowalevskii and Ptychodera flava. By comparing them with diverse bilaterian genomes, we identify shared traits that were probably inherited from the last common deuterostome ancestor, and then explore evolutionary trajectories leading from this ancestor to hemichordates, echinoderms and chordates. The hemichordate genomes exhibit extensive conserved synteny with amphioxus and other bilaterians, and deeply conserved non-coding sequences that are candidates for conserved gene-regulatory elements. Notably, hemichordates possess a deuterostome-specific genomic cluster of four ordered transcription factor genes, the expression of which is associated with the development of pharyngeal 'gill' slits, the foremost morphological innovation of early deuterostomes, and is probably central to their filter-feeding lifestyle. Comparative analysis reveals numerous deuterostome-specific gene novelties, including genes found in deuterostomes and marine microbes, but not other animals. The putative functions of these genes can be linked to physiological, metabolic and developmental specializations of the filter-feeding ancestor.

BACKGROUND: COVID-19 has infected millions of people worldwide and is responsible for several hundred thousand fatalities. The COVID-19 pandemic has necessitated thoughtful resource allocation and early identification of high-risk patients. However, effective methods to meet these needs are lacking. OBJECTIVE: The aims of this study were to analyze the electronic health records (EHRs) of patients who tested positive for COVID-19 and were admitted to hospitals in the Mount Sinai Health System in New York City; to develop machine learning models for making predictions about the hospital course of the patients over clinically meaningful time horizons based on patient characteristics at admission; and to assess the performance of these models at multiple hospitals and time points. METHODS: We used Extreme Gradient Boosting (XGBoost) and baseline comparator models to predict in-hospital mortality and critical events at time windows of 3, 5, 7, and 10 days from admission. Our study population included harmonized EHR data from five hospitals in New York City for 4098 COVID-19-positive patients admitted from March 15 to May 22, 2020. The models were first trained on patients from a single hospital (n=1514) before or on May 1, externally validated on patients from four other hospitals (n=2201) before or on May 1, and prospectively validated on all patients after May 1 (n=383). Finally, we established model interpretability to identify and rank variables that drive model predictions. RESULTS: Upon cross-validation, the XGBoost classifier outperformed baseline models, with an area under the receiver operating characteristic curve (AUC-ROC) for mortality of 0.89 at 3 days, 0.85 at 5 and 7 days, and 0.84 at 10 days. XGBoost also performed well for critical event prediction, with an AUC-ROC of 0.80 at 3 days, 0.79 at 5 days, 0.80 at 7 days, and 0.81 at 10 days. In external validation, XGBoost achieved an AUC-ROC of 0.88 at 3 days, 0.86 at 5 days, 0.86 at 7 days, and 0.84 at 10 days for mortality prediction. Similarly, the unimputed XGBoost model achieved an AUC-ROC of 0.78 at 3 days, 0.79 at 5 days, 0.80 at 7 days, and 0.81 at 10 days. Trends in performance on prospective validation sets were similar. At 7 days, acute kidney injury on admission, elevated LDH, tachypnea, and hyperglycemia were the strongest drivers of critical event prediction, while higher age, anion gap, and C-reactive protein were the strongest drivers of mortality prediction. CONCLUSIONS: We externally and prospectively trained and validated machine learning models for mortality and critical events for patients with COVID-19 at different time horizons. These models identified at-risk patients and uncovered underlying relationships that predicted outcomes.

BACKGROUND: The use of transvaginal mesh and biological graft material in prolapse surgery is controversial and has led to a number of enquiries into their safety and efficacy. Existing trials of these augmentations are individually too small to be conclusive. We aimed to compare the outcomes of prolapse repair involving either synthetic mesh inlays or biological grafts against standard repair in women. METHODS: We did two pragmatic, parallel-group, multicentre, randomised controlled trials for our study (PROSPECT [PROlapse Surgery: Pragmatic Evaluation and randomised Controlled Trials]) in 35 centres (a mix of secondary and tertiary referral hospitals) in the UK. We recruited women undergoing primary transvaginal anterior or posterior compartment prolapse surgery by 65 gynaecological surgeons in these centres. We randomly assigned participants by a remote web-based randomisation system to one of the two trials: comparing standard (native tissue) repair alone with standard repair augmented with either synthetic mesh (the mesh trial) or biological graft (the graft trial). We assigned women (1:1:1 or 1:1) within three strata: assigned to one of the three treatment options, comparison of standard repair with mesh, and comparison of standard repair with graft. Participants, ward staff, and outcome assessors were masked to randomisation where possible; masking was obviously not possible for the surgeon. Follow-up was for 2 years after the surgery; the primary outcomes, measured at 1 year and 2 years, were participant-reported prolapse symptoms (i.e. the Pelvic Organ Prolapse Symptom Score [POP-SS]) and condition-specific (ie, prolapse-related) quality-of-life scores, analysed in the modified intention-to-treat population. This trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN60695184. FINDINGS: Between Jan 8, 2010, and Aug 30, 2013, we randomly allocated 1352 women to treatment, of whom 1348 were included in the analysis. 865 women were included in the mesh trial (430 to standard repair alone, 435 to mesh augmentation) and 735 were included in the graft trial (367 to standard repair alone, 368 to graft augmentation). Because the analyses were carried out separately for each trial (mesh trial and graft trial) some women in the standard repair arm assigned to all treatment options were included in the standard repair group of both trials. 23 of these women did not receive any surgery (15 in the mesh trial, 13 in the graft trial; five were included in both trials) and were included in the baseline analyses only. Mean POP-SS at 1 year did not differ substantially between comparisons (standard 5·4 [SD 5·5] vs mesh 5·5 [5·1], mean difference 0·00, 95% CI -0·70 to 0·71; p=0·99; standard 5·5 [SD 5·6] vs graft 5·6 [5·6]; mean difference -0·15, -0·93 to 0·63; p=0·71). Mean prolapse-related quality-of-life scores also did not differ between groups at 1 year (standard 2·0 [SD 2·7] vs mesh 2·2 [2·7], mean difference 0·13, 95% CI -0·25 to 0·51; p=0·50; standard 2·2 [SD 2·8] vs graft 2·4 [2·9]; mean difference 0·13, -0·30 to 0·56; p=0·54). Mean POP-SS at 2 years were: standard 4·9 (SD 5·1) versus mesh 5·3 (5·1), mean difference 0·32, 95% CI -0·39 to 1·03; p=0·37; standard 4·9 (SD 5·1) versus graft 5·5 (5·7); mean difference 0·32, -0·48 to 1·12; p=0·43. Prolapse-related quality-of-life scores at 2 years were: standard 1·9 (SD 2·5) versus mesh 2·2 (2·6), mean difference 0·15, 95% CI -0·23 to 0·54; p=0·44; standard 2·0 (2·5) versus graft 2·2 (2·8); mean difference 0·10, -0·33 to 0·52; p=0·66. Serious adverse events such as infection, urinary retention, or dyspareunia or other pain, excluding mesh complications, occurred with similar frequency in the groups over 1 year (mesh trial: 31/430 [7%] with standard repair vs 34/435 [8%] with mesh, risk ratio [RR] 1·08, 95% CI 0·68 to 1·72; p=0·73; graft trial: 23/367 [6%] with standard repair vs 36/368 [10%] with graft, RR 1·57, 0·95 to 2·59; p=0·08). The cumulative number of women with a mesh complication over 2 years in women actually exposed to synthetic mesh was 51 (12%) of 434. INTERPRETATION: Augmentation of a vaginal repair with mesh or graft material did not improve women's outcomes in terms of effectiveness, quality of life, adverse effects, or any other outcome in the short term, but more than one in ten women had a mesh complication. Therefore, follow-up is vital to identify any longer-term potential benefits and serious adverse effects of mesh or graft reinforcement in vaginal prolapse surgery.

INTRODUCTION AND HYPOTHESIS: Maximum urethral closure pressure (MUCP) provides an objective assessment of urethral integrity, but its role in predicting outcome after midurethral sling (MUS) placement is debatable and current practice in the UK is variable. The study was carried out to determine if lower preoperative MUCP is associated with poor outcome following MUS. METHOD: The study was a retrospective review of the British Society of Urogynaecology (BSUG) database and urodynamics (UDS) data. Patients who reported outcome as "no improvement", "worse" or "much worse" on the Patient Global Impression of Improvement (PGII) scale were identified as having a poor outcome. Patients who reported "a little improvement", "improved" and "very much improved" on the PGII were thought to have a good outcome. The preoperative demographics, UDS findings and quality of life (International Consultation of Incontinence questionnaires [ICIQ-SF]) data of the two groups were compared. RESULT: A total of 236 women were identified for the study. Of these, 24 women (10.2 %) had a poor outcome. Of the remaining women reporting a good outcome, 50 cases were randomly selected. All urodynamic parameters, including mean functional urethral length (FUL), bladder capacity, and Qmax, were similar, except for mean MUCP 37.05 cm H2O, which was significantly lower in group 1 (poor outcome 37.05 cm H2O) compared with a mean MUCP of 50.6 cm H2O in group 2 (good outcome; p = 0.005). CONCLUSION: We conclude that failure following MUS is associated with preoperatively lower MUCP, which can be used as a predictor of failure.

The E3 ubiquitin ligase CRL4(Cdt2) targets proteins for destruction in S phase and after DNA damage by coupling ubiquitylation to DNA-bound proliferating cell nuclear antigen (PCNA). Coupling to PCNA involves a PCNA-interacting peptide (PIP) degron motif in the substrate that recruits CRL4(Cdt2) while binding to PCNA. In vertebrates, CRL4(Cdt2) promotes degradation of proteins whose presence in S phase is deleterious, including Cdt1, Set8, and p21. Here, we show that CRL4(Cdt2) targets thymine DNA glycosylase (TDG), a base excision repair enzyme that is involved in DNA demethylation. TDG contains a conserved and nearly perfect match to the PIP degron consensus. TDG is ubiquitylated and destroyed in a PCNA-, Cdt2-, and PIP degron-dependent manner during DNA repair in Xenopus egg extract. The protein can also be destroyed during DNA replication in this system. During Xenopus development, TDG first accumulates during gastrulation, and its expression is down-regulated by CRL4(Cdt2). Our results expand the group of vertebrate CRL4(Cdt2) substrates to include a bona fide DNA repair enzyme.

OBJECTIVE: To explore the views of a multidisciplinary group of experts and achieve consensus on the importance of perineal support in preventing obstetric anal sphincter injuries (OASIS). DESIGN: A three-generational Delphi survey. SETTING: A UK-wide survey of experts. POPULATION: A panel of 20 members consisting of obstetricians, midwives and urogynecologists recommended by UK professional bodies. METHODS: A 58-item web-based questionnaire was sent to all participants who were asked to anonymously rate the importance of each item on a six-point Likert scale. They were asked to rate their level of agreement on statements related to hands-on/hands-poised techniques, the association of hands-poised/hands-off approach with OASIS, the need to implement perineal support and the need to improve the evidence to support it. Systematic feedback of responses from previous rounds was provided to participants. MAIN OUTCOME MEASURES: To achieve consensus on key areas related to perineal support. RESULTS: The response rate was 100% in all three iterations. There was consensus that current UK practice regarding perineal protection was not based on robust evidence. The respondents agreed that hands-poised/hands-off and OASIS are causally related and that hands-poised was misinterpreted by clinicians as hands-off. Although 90% of experts agreed that some form of randomized trial was required and that all would be prepared to take part, there was also consensus (75%) that in the meantime, hands-on should be the recommended technique. CONCLUSIONS: Our results highlight the current lack of evidence to support policies of perineal support at time of birth and the need to address this controversial issue.

INTRODUCTION AND HYPOTHESIS: A terminology and standardized classification has yet to be developed for those complications related to native tissue female pelvic floor surgery. METHODS: This report on the terminology and classification combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS) and a Joint IUGA/ICS Working Group on Complications Terminology, assisted at intervals by many external referees. A process of rounds of internal and external review took place with decision-making by collective opinion (consensus). RESULTS: A terminology and classification of complications related to native tissue female pelvic floor surgery has been developed, with the classification based on category (C), time (T), and site (S) classes and divisions, that should encompass all conceivable scenarios for describing operative complications and healing abnormalities. The CTS code for each complication, involving three (or four) letters and three numerals, is likely to be very suitable for any surgical audit or registry, particularly one that is procedure-specific. Users of the classification have been assisted by case examples, color charts, and online aids (www.icsoffice.org/ntcomplication). CONCLUSIONS: A consensus-based terminology and classification report for complications in native tissue female pelvic floor surgery has been produced. It is aimed at being a significant aid to clinical practice and particularly to research.

INTRODUCTION AND HYPOTHESIS: There seems to be a temporal association between increasing use of "hands off" the perineum in labour and reduced use of episiotomy with an increasing rate of anal sphincter injuries. We aimed to determine how common the practice of "hands off" the perineum is. METHODS: An observational postal questionnaire study of 1,000 midwives in England in which the main objective was to obtain an estimate of the number of midwives practising either "hands on" or "hands off" was conducted. RESULTS: Six hundred and seven questionnaires were returned; 299 (49.3%, 95% CI 45.2-53.3%) midwives prefer the "hands-off" method. Less-experienced midwives were more likely to prefer the "hands off" (72% vs. 41.4%, p < 0.001). A higher proportion of midwives in the "hands-off" group would never do an episiotomy (37.1% vs. 24.4%, p = 0.001) for indications other than fetal distress. CONCLUSIONS: The "hands off" the perineum technique is prevalent in the management of labour. We hypothesise that a possible consequence might be an increased incidence of obstetric anal sphincter injury.

OBJECTIVES: The aim of this study was to evaluate current education and training of student and registered midwives across the UK and Spain; analysing both pelvic floor teaching and practical experience. STUDY DESIGN: A cross-sectional survey was carried out by 711 student and 384 registered midwives across different universities and regions in the UK and Spain. RESULTS: The vast majority (91.5 % nâ¯=â¯382) of UK students complete training without ever cutting or repairing an episiotomy. This compares to 39.4 % (nâ¯=â¯85) of registered midwives who did not cut an episiotomy during training. Only 20 % (nâ¯=â¯9) of Spanish and 10 % (nâ¯=â¯45) of UK registered midwives felt confident undertaking these techniques. In Spain just 15 % (nâ¯=â¯6) of students, compared to 54.8 % (nâ¯=â¯80) of registered midwives had received teaching on longer-term pelvic floor complications. CONCLUSION: There is a considerable deficit in the current training practices for midwives regarding episiotomies. This lack of practice and confidence may be impacting on the increased rates of perineal tears and pelvic dysfunction in post-partum women. Across registered midwives there are gaps in education regarding longer-term pelvic floor complications. Our study was limited by a smaller sample size from Spain compared to the UK. Our results show practical assessment of skills during training is desirable and could improve both the confidence and competence of midwives upon registration.

INTRODUCTION: Next to existing terminology of the lower urinary tract, due to its increasing complexity, the terminology for pelvic floor dysfunction in women may be better updated by a female-specific approach and clinically based consensus report. METHODS: This report combines the input of members of the Standardization and Terminology Committees of two international organizations, the International Urogynecological Association (IUGA), and the International Continence Society (ICS), assisted at intervals by many external referees. Appropriate core clinical categories and a subclassification were developed to give an alphanumeric coding to each definition. An extensive process of 15 rounds of internal and external review was developed to exhaustively examine each definition, with decision-making by collective opinion (consensus). RESULTS: A terminology report for female pelvic floor dysfunction, encompassing over 250 separate definitions, has been developed. It is clinically based with the six most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in female pelvic floor dysfunction. Female-specific imaging (ultrasound, radiology, and MRI) has been a major addition while appropriate figures have been included to supplement and help clarify the text. Ongoing review is not only anticipated but will be required to keep the document updated and as widely acceptable as possible. CONCLUSION: A consensus-based terminology report for female pelvic floor dysfunction has been produced aimed at being a significant aid to clinical practice and a stimulus for research.

INTRODUCTION AND HYPOTHESIS: To determine the reoperation rate for symptomatic recurrence of cystoceles following traditional anterior colporrhaphy (without mesh). METHODS: Retrospective case note review of 207 cases of primary anterior colporrhaphy with/without other prolapse surgery. All patients received a 3-month clinic follow-up. Reoperation details for prolapse and/or urinary incontinence were obtained from patients general practitioners with a median follow-up of 50 months. RESULTS: The median age was 60 years (32-85), and median parity was 2. Twenty-nine of 207 (14%) patients had previous gynecological surgery. While the anatomical recurrence rate of cystoceles at 3 months postoperatively was 12%, the reoperation rate for recurrent cystocele by 50 months was 3.4%. Overall, 9.1% of the group underwent prolapse or incontinence surgery during this period. CONCLUSIONS: While the anatomical recurrence rates for cystocele following traditional anterior colporrhaphy might be high, the low reoperation rate at more than 4 years (3.4%) suggests that patient's symptoms might not be bothersome enough to require further surgery. Both subjective and anatomical outcomes are required to assess the outcome of both traditional and new prolapse procedures.

Early detection of patients at risk for clinical deterioration is crucial for timely intervention. Traditional detection systems rely on a limited set of variables and are unable to predict the time of decline. We describe a machine learning model called MEWS++ that enables the identification of patients at risk of escalation of care or death six hours prior to the event. A retrospective single-center cohort study was conducted from July 2011 to July 2017 of adult (age > 18) inpatients excluding psychiatric, parturient, and hospice patients. Three machine learning models were trained and tested: random forest (RF), linear support vector machine, and logistic regression. We compared the models' performance to the traditional Modified Early Warning Score (MEWS) using sensitivity, specificity, and Area Under the Curve for Receiver Operating Characteristic (AUC-ROC) and Precision-Recall curves (AUC-PR). The primary outcome was escalation of care from a floor bed to an intensive care or step-down unit, or death, within 6 h. A total of 96,645 patients with 157,984 hospital encounters and 244,343 bed movements were included. Overall rate of escalation or death was 3.4%. The RF model had the best performance with sensitivity 81.6%, specificity 75.5%, AUC-ROC of 0.85, and AUC-PR of 0.37. Compared to traditional MEWS, sensitivity increased 37%, specificity increased 11%, and AUC-ROC increased 14%. This study found that using machine learning and readily available clinical data, clinical deterioration or death can be predicted 6 h prior to the event. The model we developed can warn of patient deterioration hours before the event, thus helping make timely clinical decisions.
ABSTRACT
OBJECTIVE: The COVID-19 pandemic is a global public health crisis, with over 33 million cases and 999 000 deaths worldwide. Data are needed regarding the clinical course of hospitalised patients, particularly in the USA. We aimed to compare clinical characteristic of patients with COVID-19 who had in-hospital mortality with those who were discharged alive. DESIGN: Demographic, clinical and outcomes data for patients admitted to five Mount Sinai Health System hospitals with confirmed COVID-19 between 27 February and 2 April 2020 were identified through institutional electronic health records. We performed a retrospective comparative analysis of patients who had in-hospital mortality or were discharged alive. SETTING: All patients were admitted to the Mount Sinai Health System, a large quaternary care urban hospital system. PARTICIPANTS: Participants over the age of 18 years were included. PRIMARY OUTCOMES: We investigated in-hospital mortality during the study period. RESULTS: A total of 2199 patients with COVID-19 were hospitalised during the study period. As of 2 April, 1121 (51%) patients remained hospitalised, and 1078 (49%) completed their hospital course. Of the latter, the overall mortality was 29%, and 36% required intensive care. The median age was 65 years overall and 75 years in those who died. Pre-existing conditions were present in 65% of those who died and 46% of those discharged. In those who died, the admission median lymphocyte percentage was 11.7%, D-dimer was 2.4 µg/mL, C reactive protein was 162 mg/L and procalcitonin was 0.44 ng/mL. In those discharged, the admission median lymphocyte percentage was 16.6%, D-dimer was 0.93 µg/mL, C reactive protein was 79 mg/L and procalcitonin was 0.09 ng/mL. CONCLUSIONS: In our cohort of hospitalised patients, requirement of intensive care and mortality were high. Patients who died typically had more pre-existing conditions and greater perturbations in inflammatory markers as compared with those who were discharged.
