Long acting progestogens versus combined oral contraceptive pill for preventing recurrence of endometriosis related pain: the PRE-EMPT pragmatic, parallel group, open label, randomised controlled trial.

OBJECTIVES: To evaluate the clinical effectiveness of long acting progestogens compared with the combined oral contraceptive pill in preventing recurrence of endometriosis related pain. DESIGN: The PRE-EMPT (preventing recurrence of endometriosis) pragmatic, parallel group, open label, randomised controlled trial. SETTING: 34 UK hospitals. PARTICIPANTS: 405 women of reproductive age undergoing conservative surgery for endometriosis. INTERVENTIONS: Participants were randomised in a 1:1 ratio using a secure internet facility to a long acting progestogen (depot medroxyprogesterone acetate or levonorgestrel releasing intrauterine system) or the combined oral contraceptive pill. MAIN OUTCOME MEASURES: The primary outcome was pain measured three years after randomisation using the pain domain of the Endometriosis Health Profile 30 (EHP-30) questionnaire. Secondary outcomes (evaluated at six months, one, two, and three years) included the four core and six modular domains of the EHP-30, and treatment failure (further therapeutic surgery or second line medical treatment). RESULTS: 405 women were randomised to receive a long acting progestogen (n=205) or combined oral contraceptive pill (n=200). At three years, there was no difference in pain scores between the groups (adjusted mean difference -0.8, 95% confidence interval -5.7 to 4.2, P=0.76), which had improved by around 40% in both groups compared with preoperative values (an average of 24 and 23 points for long acting progestogen and combined oral contraceptive pill groups, respectively). Most of the other domains of the EHP-30 also showed improvement at all time points compared with preoperative scores, without evidence of any differences between groups. Women randomised to a long acting progestogen underwent fewer surgical procedures or second line treatments compared with those randomised to the combined oral contraceptive pill group (73 v 97; hazard ratio 0.67, 95% confidence interval 0.44 to 1.00). CONCLUSIONS: Postoperative prescription of a long acting progestogen or the combined oral contraceptive pill results in similar levels of improvement in endometriosis related pain at three years, with both groups showing around a 40% improvement compared with preoperative levels. While women can be reassured that both options are effective, the reduced risk of repeat surgery for endometriosis and hysterectomy might make long acting reversible progestogens preferable for some.

LAparoscopic Versus Abdominal hysterectomy (LAVA): protocol of a randomised controlled trial.

INTRODUCTION: There is uncertainty about the advantages and disadvantages of laparoscopic hysterectomy compared with abdominal hysterectomy, particularly the relative rate of complications of the two procedures. While uptake of laparoscopic hysterectomy has been slow, the situation is changing with greater familiarity, better training, better equipment and increased proficiency in the technique. Thus, a large, robust, multicentre randomised controlled trial (RCT) is needed to compare contemporary laparoscopic hysterectomy with abdominal hysterectomy to determine the safest and most cost-effective technique. METHODS AND ANALYSIS: A parallel, open, non-inferiority, multicentre, randomised controlled, expertise-based surgery trial with integrated health economic evaluation and an internal pilot with an embedded qualitative process evaluation. A within trial-based economic evaluation will explore the cost-effectiveness of laparoscopic hysterectomy compared with open abdominal hysterectomy. We will aim to recruit 3250 women requiring a hysterectomy for a benign gynaecological condition and who were suitable for either laparoscopic or open techniques. The primary outcome is major complications up to six completed weeks postsurgery and the key secondary outcome is time from surgery to resumption of usual activities using the personalised Patient-Reported Outcomes Measurement Information System Physical Function questionnaire. The principal outcome for the economic evaluation is to be cost per QALY at 12 months' postsurgery. A secondary analysis is to be undertaken to generate costs per major surgical complication avoided and costs per return to normal activities. ETHICS AND DISSEMINATION: The study was approved by the West Midlands-Edgbaston Research Ethics Committee, 18 February 2021 (Ethics ref: 21/WM/0019). REC approval for the protocol version 2.0 dated 2 February 2021 was issued on 18 February 2021.We will present the findings in national and international conferences. We will also aim to publish the findings in high impact peer-reviewed journals. We will disseminate the completed paper to the Department of Health, the Scientific Advisory Committees of the RCOG, the Royal College of Nurses (RCN) and the BSGE.

Effectiveness of laparoscopic removal of isolated superficial peritoneal endometriosis for the management of chronic pelvic pain in women (ESPriT2): protocol for a multi-centre randomised controlled trial.

BACKGROUND: Endometriosis affects 190 million women and those assigned female at birth worldwide. For some, it is associated with debilitating chronic pelvic pain. Diagnosis of endometriosis is often achieved through diagnostic laparoscopy. However, when isolated superficial peritoneal endometriosis (SPE), the most common endometriosis subtype, is identified during laparoscopy, limited evidence exists to support the common decision to surgically remove it via excision or ablation. Improved understanding of the impact of surgical removal of isolated SPE for the management of chronic pelvic pain in women is required. Here, we describe our protocol for a multi-centre trial to determine the effectiveness of surgical removal of isolated SPE for the management of endometriosis-associated pain. METHODS: We plan to undertake a multi-centre participant-blind parallel-group randomised controlled clinical and cost-effectiveness trial with internal pilot. We plan to randomise 400 participants from up to 70 National Health Service Hospitals in the UK. Participants with chronic pelvic pain awaiting diagnostic laparoscopy for suspected endometriosis will be consented by the clinical research team. If isolated SPE is identified at laparoscopy, and deep or ovarian endometriosis is not seen, participants will be randomised intraoperatively (1:1) to surgical removal (by excision or ablation or both, according to surgeons' preference) versus diagnostic laparoscopy alone. Randomisation with block-stratification will be used. Participants will be given a diagnosis but will not be informed of the procedure they received until 12 months post-randomisation, unless required. Post-operative medical treatment will be according to participants' preference. Participants will be asked to complete validated pain and quality of life questionnaires at 3, 6 and 12 months after randomisation. Our primary outcome is the pain domain of the Endometriosis Health Profile-30 (EHP-30), via a between randomised group comparison of adjusted means at 12 months. Assuming a standard deviation of 22 points around the pain score, 90% power, 5% significance and 20% missing data, 400 participants are required to be randomised to detect an 8-point pain score difference. DISCUSSION: This trial aims to provide high quality evidence of the clinical and cost-effectiveness of surgical removal of isolated SPE. TRIAL REGISTRATION: ISRCTN registry ISRCTN27244948.

PROSPECT: 4- and 6-year follow-up of a randomised trial of surgery for vaginal prolapse.

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.

Cognition/Psychological Burden and Resilience in Cutaneous T-Cell Lymphoma and Psoriasis Patients: Real-Life Data and Implications for the Treatment.

Background: Psoriasis and cutaneous T-cell lymphoma (CTCL) expose patients to chronic inflammation as well as physical and psychological disabilities, but the impact of such alterations on cognitive function is unknown. Objective: This study is aimed at determining if CTCL and psoriasis impact cognitive functioning in relation to psychological and health-related quality of life (HR-QOL) status. Methods: A cross-sectional study was performed in an outpatient dermatology clinic of a university teaching hospital. Thirty-nine subjects with CTCL (N = 20) or psoriasis (N = 19) who met eligibility criteria were included. The cognitive domains of memory, attention and processing speed, and executive function were assessed with standard neuropsychological tests. Subjects were assessed for depression, anxiety, and HR-QOL (using the SKINDEX-29 questionnaire). Results: Study participants were CTCL and psoriasis subjects; cognitive impairment was found in the domain of memory in 17.9% subjects with CTCL or psoriasis. Lower scores on executive function tests were predicted by higher (worse HR-QOL) SKINDEX-29 functioning scores (p = 0.01). A higher estimated baseline intellectual functioning predicted lower scores (better HR-QOL) on the symptoms and functioning domains of SKINDEX-29 (p = 0.01 and 0.02, respectively) and a statistical trend (p = 0.07) for the emotion domain. Memory and acute anxiety were adversely impacted by shorter disease duration (p = 0.01 for both). Conclusions: Memory impairment may be associated comorbidity in CTCL and psoriasis. Subjects with stronger cognitive resources appear to cope better with health-related quality of life (HR-QOL) challenges.

A Retrospective Characterization of Dexmedetomidine-Suspected Fever and Its Consequences in Adult Critically Ill Patients.

BACKGROUND: Current evidence for dexmedetomidine-suspected fever (DSF) is limited. Lack of recognition may lead to costly or potentially harmful interventions for critically ill patients. OBJECTIVE: The primary objective was to characterize escalations of care related to DSF. Secondary objectives were to describe the incidence, severity, and consequences associated with DSF. METHODS: A retrospective review was conducted in critically ill adults who developed fever ≥39°C within 12 h from initiation of dexmedetomidine, with resolution of fever to <39°C within 12 h after discontinuation. The primary outcome was percentage of patients who received an escalation of care due to fever. Secondary outcomes included the percentage of patients who developed a multidrug-resistant organism or Clostridium difficile infection. RESULTS: Eighteen of 3943 patients screened in 4099 encounters met criteria for DSF (0.4%). The majority were white (83.3%), male (66.7%), and underwent cardiac surgery (61.1%). Median (interquartile range [IQR]) time to fever onset and resolution were 5.5 (3.6-7.6) and 1.3 (1.0-2.9) h. Nine patients (50%) underwent infectious workup including antimicrobial initiation (n = 1, 5.6%), broadening of antimicrobials (n = 4, 22.2%), or culture collection (n = 9, 50%). Eleven patients (61.1%) underwent attempted temperature reduction. Twelve patients (66.7%) underwent diagnostic imaging. Incidence of multidrug-resistant organism and C. difficile infection were low (11.1 and 16.7% of fever patients, respectively). CONCLUSION AND RELEVANCE: Incidence of DSF was low and more common in cardiac surgery patients. Unrecognized DSF led to an escalation of care in most patients. Dexmedetomidine exposure should be considered as a potential cause of fever in critically ill adults.

Healthy myeloid-derived suppressor cells express the surface ectoenzyme Vanin-2 (VNN2).

Study of human monocytic Myeloid-Derived Suppressor cells Mo-MDSC (CD14+ HLA-DRneg/low) has been hampered by the lack of positive cell-surface markers. In order to identify positive markers for Mo-MDSC, we performed microarray analysis comparing Mo-MDSC cells from healthy subjects versus CD14+ HLA-DRhigh monocytes. We have identified the surface ectoenzyme Vanin-2(VNN2) protein as a novel biomarker highly-enriched in healthy subjects Mo-MDSC. Indeed, healthy subjects Mo-MDSC cells expressed 68 % VNN2, whereas only 9% VNN2 expression was observed on CD14+ HLA-DRhigh cells (n = 4 p < 0.01). The top 10 percent positive VNN2 monocytes expressed CD33 and CD11b while being negative for HLA-DR, CD3, CD15, CD19 and CD56, consistent with a Mo-MDSC phenotype. CD14+VNN2high monocytes were able to inhibit CD8 T cell proliferation comparably to traditional Mo-MDSC at 51 % and 48 % respectively. However, VNN2 expression on CD14+ monocytes from glioma patients was inversely correlated to their grade. CD14+VNN2high monocytes thus appear to mark a monocytic population similar to Mo-MDSC only in healthy subjects, which may be useful for tumor diagnoses.

Fabrication and Validation of an Economical, Programmable, Dual-Channel, Electronic Cigarette Aerosol Generator.

Vaping (inhalation of electronic cigarette-generated aerosol) is a public health concern. Due to recent spikes in adolescent use of electronic cigarettes (ECIGs) and vaping-induced illnesses, demand for scientific inquiry into the physiological effects of electronic cigarette (ECIG) aerosol has increased. For such studies, standardized and consistent aerosol production is required. Many labs generate aerosol by manually activating peristaltic pumps and ECIG devices simultaneously in a predefined manner. The tedium involved with this process (large puff number over time) and risk of error in keeping with puff topography (puff number, duration, interval) are less than optimal. Furthermore, excess puffing on an ECIG device results in battery depletion, reducing aerosol production, and ultimately, its chemical and physical nature. While commercial vaping machines are available, the cost of these machines is prohibitive to many labs. For these reasons, an economical and programmable ECIG aerosol generator, capable of generating aerosol from two atomizers simultaneously, was fabricated, and subsequently validated. Validation determinants include measurements of atomizer temperatures (inside and outside), electrical parameters (current, resistance and power) of the circuitry, aerosol particle distribution (particle counts and mass concentrations) and aerosol delivery (indexed by nicotine recovery), all during stressed conditions of four puffs/minute for 75 min (i.e., 300 puffs). Validation results indicate that the ECIG aerosol generator is better suited for experiments involving ≤100 puffs. Over 100 puffs, the amount of variation in the parameters measured tends to increase. Variations between channels are generally higher than variations within a channel. Despite significant variations in temperatures, electrical parameters, and aerosol particle distributions, both within and between channels, aerosol delivery remains remarkably stable for up to 300 puffs, yielding over 25% nicotine recovery for both channels. In conclusion, this programmable, dual-channel ECIG aerosol generator is not only affordable, but also allows the user to control puff topography and eliminate battery drain of ECIG devices. Consequently, this aerosol generator is valid, reliable, economical, capable of using a variety of E-liquids and amenable for use in a vast number of studies investigating the effects of ECIG-generated aerosol while utilizing a multitude of puffing regimens in a standardized manner.

Computational Drug Repositioning Identifies Statins as Modifiers of Prognostic Genetic Expression Signatures and Metastatic Behavior in Melanoma.

Despite advances in melanoma treatment, more than 70% of patients with distant metastasis die within 5 years. Proactive treatment of early melanoma to prevent metastasis could save lives and reduce overall healthcare costs. Currently, there are no treatments specifically designed to prevent early melanoma from progressing to metastasis. We used the Connectivity Map to conduct an in silico drug screen and identified 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors (statins) as a drug class that might prevent melanoma metastasis. To confirm the in vitro effect of statins, RNA sequencing was completed on A375 cells after treatment with fluvastatin to describe changes in the melanoma transcriptome. Statins induced differential expression in genes associated with metastasis and are used in commercially available prognostic tests for melanoma metastasis. Finally, we completed a chart review of 475 patients with melanoma. Patients taking statins were less likely to have metastasis at the time of melanoma diagnosis in both univariate and multivariate analyses (24.7% taking statins vs. 37.6% not taking statins, absolute risk reduction = 12.9%, P = 0.038). These findings suggest that statins might be useful as a treatment to prevent melanoma metastasis. Prospective trials are required to verify our findings and to determine the mechanism of metastasis prevention.

Laparoscopic treatment of isolated superficial peritoneal endometriosis for managing chronic pelvic pain in women: study protocol for a randomised controlled feasibility trial (ESPriT1).

BACKGROUND: Endometriosis (where endometrial-like tissue is found outside the uterus) affects ~ 176 million women worldwide and can lead to debilitating pelvic pain. Three subtypes of endometriosis exist, with ~ 80% of women having superficial peritoneal endometriosis (SPE). Endometriosis is diagnosed by laparoscopy and, if SPE is found, gynaecologists usually remove it surgically. However, many women get limited pain relief from surgical removal of SPE. We plan to undertake a future large trial where women who have only SPE found at initial laparoscopy are randomly allocated to have surgical removal (excision or ablation) of SPE, or not. Ultimately, we want to determine whether surgical removal improves overall symptoms and quality of life, or whether surgery is of no benefit, exacerbates symptoms, or even causes harm. The primary objective of this feasibility study is to determine what proportion of women with suspected SPE undergoing diagnostic laparoscopy will agree to randomisation. The secondary objectives are to determine if there are differences in key prognostic parameters between eligible women that agree to be randomised and those that decline; how many women having laparoscopy for investigation of chronic pelvic pain are eligible for the trial; the range of treatment effects and variability in outcomes and the most acceptable methods of recruitment, randomisation and assessment tools. METHODS: We will recruit up to 90 women with suspected SPE undergoing diagnostic laparoscopy over a 9-month recruitment period in four Scottish hospitals and randomise them 1:1 to either diagnostic laparoscopy alone (with a sham port to achieve blinding of the allocation) or surgical removal of endometriosis. Baseline characteristics, e.g. age, index of social deprivation, ethnicity, and intensity/duration of pain will be collected. Participants will be followed up by online questionnaires assessing pain, physical and emotional function at baseline, 3 months, 6 months and 12 months. DISCUSSION: Recruitment to a randomised controlled trial to assess the effectiveness of surgery for endometriosis may be challenging because of preconceived ideas about treatment success amongst patients and clinicians. We have designed this study to assess feasibility of recruitment and to inform the design of our future definitive trial. TRIAL REGISTRATION: ClincicalTrials.gov, NCT04081532 STATUS: Recruiting.

Extraction of Electronic Health Record Data using Fast Healthcare Interoperability Resources for Automated Breast Cancer Risk Assessment.

Women at high risk for breast cancer may benefit from enhanced screening and risk-reduction strategies. However, limited time during clinical encounters is one barrier to routine breast cancer risk assessment. We evaluated if electronic health record (EHR) data downloaded using Fast Healthcare Interoperability Resources (FHIR) is sufficient for breast cancer risk calculation in our decision support tools, RealRisks and BNAV. We accessed EHR data using FHIR for six patient advocates, and downloaded and parsed XML documents. We searched for relevant clinical variables, and evaluated if data was sufficient to calculate risk using validated models (Gail, Breast Cancer Screening Consortium [BCSC], BRCAPRO). While only one advocate had sufficient EHR data to calculate risk using the BCSC model only, we identified variables including age, race/ethnicity, mammographic density, and prior breast biopsy in most advocates. EHR data from FHIR could be incorporated into automated breast cancer risk calculation in clinical decision support tools.

Macrophage Response to Simulated Solar Radiation in the Development of Human Malignant Melanoma.

Background: IFN-γ is widely debated regarding its purported anti- or pro-tumorigenic properties. We initiated a pilot study of primary malignant melanoma patients to investigate whether macrophage-derived IFN-γ is produced in humans as proposed in murine melanomagenesis models. Methods: Biopsy specimens of fresh-frozen primary melanoma tissue were used to quantify co-localization of IFN-γ, macrophages, lymphocytes, and downstream IFN-γ signatures. Additionally, we analyzed simulated solar radiation (SSR) exposed skin in patients with a history of melanoma versus healthy controls to compare the relative magnitude of macrophage infiltration. Results: Our data identified a subset of tumor infiltrating CD68+ macrophages that co-localized with IFN-γ (Pearson's Correlation = 0.33 ± 0.11) in patients with primary melanoma (Stage 0-III). Additionally, a population of infiltrating CD3+ lymphocytes strongly co-localized with IFN-γ (Pearson's Correlation = 0.57 ± 0.11). Malignant melanoma cells were double positive for downstream IFN-γ response elements, MIG/CXCL9, and phosphorylated STAT-1 (P-STAT-1). Cellular signaling pathways were also observed when we exposed the skin of melanoma patients to SSR. Despite robust CXCL9 expression in the epidermis of SSR-exposed skin of melanoma patients, we observed decreased macrophage infiltration into melanoma patient skin. Conclusion: Peritumoral macrophages in melanoma patient skin produce IFN-γ and melanocytes appear to exhibit in vivo responsiveness to IFN-γ, such as P-STAT-1 and upregulated CXCL9 expression. However, despite producing CXCL9 in response to SSR, the normal skin of melanoma patients demonstrates a weak leukocyte infiltration. Immune-modulatory studies for the prevention or treatment of human malignant melanoma may need to address complex tissue and melanocyte signaling and crosstalk.

A Liquid Biopsy to Assess Brain Tumor Recurrence: Presence of Circulating Mo-MDSC and CD14+ VNN2+ Myeloid Cells as Biomarkers That Distinguish Brain Metastasis From Radiation Necrosis Following Stereotactic Radiosurgery.

BACKGROUND: Brain metastases (BM) are the most common type of brain tumor malignancy in the US. They are also the most common indication for stereotactic radiosurgery (SRS). However, the incidence of both local recurrence and radiation necrosis (RN) is increasing as treatments improve. MRI imagery often fails to differentiate BM from RN; thus, patients must often undergo surgical biopsy or resection to obtain a definitive diagnosis. OBJECTIVE: To hypothesize that a marker of immunosuppression might serve as a surrogate marker to differentiate patients with active vs inactive cancer-including RN. METHODS: We thus purified and quantified Monocytic Myeloid-Derived Suppressor Cells (Mo-MDSC) by flow cytometry in patients proven by biopsy to represent BM or RN. RESULTS: We report the utility of the previously reported HLA-Dr-Vnn2 Index or DVI to discriminate recurrent BM from RN using peripheral blood. The presence of CD14+ HLA-DRneg/low Mo-MDSC is significantly increased in the peripheral blood of patients with brain metastasis recurrence compared to RN (Average 61.5% vs 7%, n = 10 and n = 12, respectively, P < .0001). In contrast, expression of VNN2 on circulating CD14+ monocytes is decreased in BM patients compared to patients with RN (5.5% vs 26.5%, n = 10 and n = 12, respectively, P = .0008). In patients with biopsy confirmed recurrence of brain metastasis, the average DVI was 11.65, whereas the average DVI for RN patients was consistently <1 (Avg. of 0.17). CONCLUSION: These results suggest that DVI could be a useful diagnostic tool to differentiate recurrent BM from RN using a minimally invasive blood sample.

Surgery for women with endometrioma prior to in vitro fertilisation: proposal for a feasible multicentre randomised clinical trial in the UK.

STUDY QUESTION: Is it feasible to undertake a randomised controlled trial to establish whether surgical removal of endometrioma or not, improves live birth rates from IVF? SUMMARY ANSWER: A randomised controlled trial (RCT) comparing surgery versus no surgery to endometrioma prior to IVF is only feasible in UK if an adaptive rather than traditional study design is used; this would minimise resource wastage and complete the trial in an acceptable time frame. WHAT IS KNOWN ALREADY: There is wide variation in the management of endometriomas prior to IVF, with decisions about treatment being influenced by personal preferences. STUDY DESIGN SIZE AND DURATION: This was a mixed-methods study consisting of an online survey of clinicians, a focus group and individual interviews with potential trial participants. PARTICIPANTS/MATERIALS SETTING METHODS: Endometriosis and fertility experts across the UK were invited to participate in an online anonymised questionnaire. Potential future trial participants were recruited from a tertiary care fertility centre and invited to participate in either individual interviews or focus groups. MAIN RESULTS AND THE ROLE OF CHANCE: Clinicians and potential trial participants confirmed the need for an RCT to inform the management of an endometrioma prior to IVF. There were 126 clinicians who completed the survey, and the majority (70%) were willing to recruit to a trial. Half of those who responded indicated that they see at least 10 eligible women each year. The main barriers to recruitment were waiting lists for surgery and access to public funding for IVF. One focus group (n = 7) and five interviews were conducted with potential trial participants (n = 3) and their partners (n = 2). The findings from these discussions highlighted that recruitment and retention in a potential RCT could be improved by coordination between IVF and surgical services such that an operation does not delay IVF or affect access to public funding. Live birth was considered the most important outcome with an improvement of at least 10% considered the minimum acceptable by both patients and clinicians. LIMITATIONS REASONS FOR CAUTION: This feasibility study captured views of clinicians across the UK, but as patients were from a single Scottish centre, their views may not be representative of other areas with limited public funding for IVF. WIDER IMPLICATIONS OF THE FINDINGS: There is a need for an appropriately powered RCT to establish whether or not surgical treatment of endometrioma prior to IVF improves live birth rates. There are logistical issues to be considered due to limited number of participants, funding of IVF and waiting times. These could be overcome in a RCT by using an adaptive design which would include a prospectively planned opportunity for modification of specified aspects of the study design based on interim analysis of the data, coordination of IVF treatments and endometriosis surgeries and international collaboration. Similar principles could be used for other questions in fertility where a traditional approach for randomised trials is not feasible.

Surgical interventions for uterine prolapse and for vault prolapse: the two VUE RCTs.

BACKGROUND: New surgical approaches for apical prolapse have gradually been introduced, with few prospective randomised controlled trial data to evaluate their safety and efficacy compared with traditional methods. OBJECTIVE: To compare surgical uterine preservation with vaginal hysterectomy in women with uterine prolapse and abdominal procedures with vaginal procedures in women with vault prolapse in terms of clinical effectiveness, adverse events, quality of life and cost-effectiveness. DESIGN: Two parallel randomised controlled trials (i.e. Uterine and Vault). Allocation was by remote web-based randomisation (1 : 1 ratio), minimised on the need for concomitant anterior and/or posterior procedure, concomitant incontinence procedure, age and surgeon. SETTING: UK hospitals. PARTICIPANTS: Uterine trial - 563 out of 565 randomised women had uterine prolapse surgery. Vault trial - 208 out of 209 randomised women had vault prolapse surgery. INTERVENTIONS: Uterine trial - uterine preservation or vaginal hysterectomy. Vault trial - abdominal or vaginal vault suspension. MAIN OUTCOME MEASURES: The primary outcome measures were women's prolapse symptoms (as measured using the Pelvic Organ Prolapse Symptom Score), prolapse-specific quality of life and cost-effectiveness (as assessed by incremental cost per quality-adjusted life-year). RESULTS: Uterine trial - adjusting for baseline and minimisation covariates, the mean Pelvic Organ Prolapse Symptom Score at 12 months for uterine preservation was 4.2 (standard deviation 4.9) versus vaginal hysterectomy with a Pelvic Organ Prolapse Symptom Score of 4.2 (standard deviation 5.3) (mean difference -0.05, 95% confidence interval -0.91 to 0.81). Serious adverse event rates were similar between the groups (uterine preservation 5.4% vs. vaginal hysterectomy 5.9%; risk ratio 0.82, 95% confidence interval 0.38 to 1.75). There was no difference in overall prolapse stage. Significantly more women would recommend vaginal hysterectomy to a friend (odds ratio 0.39, 95% confidence interval 0.18 to 0.83). Uterine preservation was £235 (95% confidence interval £6 to £464) more expensive than vaginal hysterectomy and generated non-significantly fewer quality-adjusted life-years (mean difference -0.004, 95% confidence interval -0.026 to 0.019). Vault trial - adjusting for baseline and minimisation covariates, the mean Pelvic Organ Prolapse Symptom Score at 12 months for an abdominal procedure was 5.6 (standard deviation 5.4) versus vaginal procedure with a Pelvic Organ Prolapse Symptom Score of 5.9 (standard deviation 5.4) (mean difference -0.61, 95% confidence interval -2.08 to 0.86). The serious adverse event rates were similar between the groups (abdominal 5.9% vs. vaginal 6.0%; risk ratio 0.97, 95% confidence interval 0.27 to 3.44). The objective anterior prolapse stage 2b or more was higher in the vaginal group than in the abdominal group (odds ratio 0.38, 95% confidence interval 0.18 to 0.79). There was no difference in the overall prolapse stage. An abdominal procedure was £570 (95% confidence interval £459 to £682) more expensive than a vaginal procedure and generated non-significantly more quality-adjusted life-years (mean difference 0.004, 95% confidence interval -0.031 to 0.041). CONCLUSIONS: Uterine trial - in terms of efficacy, quality of life or adverse events in the short term, no difference was identified between uterine preservation and vaginal hysterectomy. Vault trial - in terms of efficacy, quality of life or adverse events in the short term, no difference was identified between an abdominal and a vaginal approach. FUTURE WORK: Long-term follow-up for at least 6 years is ongoing to identify recurrence rates, need for further prolapse surgery, adverse events and cost-effectiveness.

About 1 in 10 women has pelvic organ prolapse (POP) surgery, and around three of these women require a further operation. The aim of this study was to identify the most appropriate surgery for two different types of POP found in women: (1) when the uterus itself has come down ­ the Uterine trial ­ and (2) when a previous hysterectomy has resulted in the top of the vagina coming down ­ the Vault trial. In the Uterine trial, preserving the uterus was compared with removing it vaginally. In the Vault trial, uplifting and supporting the vault prolapse using an abdominal approach was compared with a vaginal approach. Women were asked about their prolapse and other symptoms affecting their quality of life (QoL). The majority of women reported that their prolapse symptoms and QoL improved after surgery. The women's prolapse was also measured by clinical examination before and 12 months after their operation. All of these results were compared between the different procedures. It was found that all the surgical procedures were successful within the 12-month review period. Abdominal surgery in the Vault trial as well as any that was required in the Uterine trial, was, however, slightly less cost-effective. Serious complications and the need for further prolapse surgery were similar in all groups. A small number of women did require additional surgery for prolapse recurrence or for small mesh exposure when additional or prolapse procedures had involved mesh. Women in both trials will be followed up for at least 6 years to determine longer-term costs and consequences.

Psoriasis and Psoriatic Arthritis Cardiovascular Disease Endotypes Identified by Red Blood Cell Distribution Width and Mean Platelet Volume.

In a subset of psoriasis (PsO) and psoriatic arthritis (PsA) patients, the skin and/or joint lesions appear to generate biologically significant systemic inflammation. Red cell distribution width (RDW) and mean platelet volume (MPV) are readily available clinical tests that reflect responses of the bone marrow and/or plasma thrombogenicity (e.g., inflammation), and can be markers for major adverse cardiac events (MACE). We aimed to evaluate if RDW and MPV may be employed as inexpensive, routinely obtained biomarkers in predicting myocardial infarction (MI), atrial fibrillation (AF), and chronic heart failure (CHF) in psoriatic and psoriatic arthritis patients. The study was divided into two parts: (a) case control study employing big data (Explorys) to assess MPV and RDW in psoriasis, psoriatic arthritis and control cohorts; (b) a clinical observational study to validate the predictive value of RDW and to evaluate RDW response to anti-psoriatic therapies. We used Explorys, an aggregate electronic database, to identify psoriatic patients with available MPV and RDW data and compared them to gender and age matched controls. The incidence of myocardial infarction (MI), atrial fibrillation (AF), and chronic heart failure (CHF) was highest among patients with both elevated RDW and MPV, followed by patients with high RDW and normal MPV. RDW elevation among PsA patients was associated with an increased risk of MI, AF, and CHF. In a local clinical cohort, high RDWs were concentrated in a subset of patients who also had elevated circulating resistin levels. Among a small subset of participants who were treated with various systemic and biologic therapies, and observed over a year, and in whom RDW was elevated at baseline, a sustained response to therapy was associated with a decrease in RDW. RDW and MPV, tests commonly contained within routine complete blood count (CBC), may be a cost-effective manner to identify PsO and PsA patients at increased risk of MACE.
