Abstract
Background In March 2020, Pain Management Services were obliged to cease face-to-face consultations. This abrupt change, in line with recommendations from the British Pain Society, aimed to protect patients and staff and allowed resource re-allocation. Pain services were obliged to switch to remote consultations using Video Tele-Conferencing Technology (VTC) and Remote Consultations (RC) either through telephone or video calls using a variety of media and software applications. Little is known about the patient experience of remotely delivered pain care especially when alternatives are removed. The aim of this work was to understand the patient experience of this necessary switch regarding pain self-management interventions during the initial stages of the COVID-19 pandemic. Methods A mixed-methods evaluation of the patient experience from three pain self-management interventions, taking place in a large community-based pain rehabilitation service along the South Coast of England, was performed. Experience-Based Design (EBD) methods were used to map patient experience at touch points through two interventions that were delivered in a structured format. Semi-structured recorded interviews were transcribed and analysed using thematic analysis for the third. Findings Fifty-eight patients took part covering the scope of the service. In general, educational and psychological sessions were well received, with physical rehabilitation components being less easy to convey remotely. Attrition rates were high for the pain management programme. Group pain education worked particularly well in an online format with hope being the predominant emotion experienced. Clear limitations were technical failures and the lack of ability to form relationships in a virtual world. Conclusions Remote digitalised interventions were acceptable to most patients. Attention should be paid to access and improving social aspects of delivery when considering such interventions. Physiotherapy may require more face-to-face necessitating a hybrid model and needs further investigation. EBD proved a highly suitable approach.

Abstract
Objective To improve the understanding of endometriosis and to provide evidence-based guidelines for the diagnosis and management of endometriosis. Outcomes Outcomes evaluated include the impact of the medical and surgical management of endometriosis on women's experience of morbidity and infertility. Methods Members of the guideline committee were selected on the basis of individual expertise to represent a range of practical and academic experience in terms of both location in Canada and type of practice, as well as subspecialty expertise along with general gynaecology background. The committee reviewed all available evidence in the English and French medical literature and available data from a survey of Canadian women. Recommendations were established as consensus statements. The final document was reviewed and approved by the Executive and Council of the SOGC. Results This document provides a summary of up-to-date evidence regarding diagnosis, investigations, and medical and surgical management of endometriosis. The resulting recommendations may be adapted by individual health care workers when serving women with this condition. Conclusions Endometriosis is a common and sometimes debilitating condition for women of reproductive age. A multidisciplinary approach involving a combination of lifestyle modifications, medications, and allied health services should be used to limit the impact of this condition on activities of daily living and fertility. In some circumstances surgery is required to confirm the diagnosis and provide therapy to achieve the desired goal of pain relief or improved fecundity. Women who find an acceptable management strategy for this condition may have an improved quality of life or attain their goal of successful pregnancy. Evidence Medline and Cochrane databases were searched for articles in English and French on subjects related to endometriosis, pelvic pain, and infertility from January 1999 to October 2009 in order to prepare a Canadian consensus guideline on the management of endometriosis. Values The quality of evidence was rated with use of the criteria described by the Canadian Task Force on Preventive Health Care. Recommendations for practice were ranked according to the method described by the Task Force. See Table 1. Benefits, harms, and costs Implementation of the guideline recommendations will improve the care of women with pain and infertility associated with endometriosis.

The strong prognostic value of KELIM, a model-based parameter from CA 125 kinetics in ovarian cancer: data from CALYPSO trial (a GINECO-GCIG study). Gynecol Oncol 2013; 130:289-94.

Abstract
BACKGROUND Unexpected results were recently reported about the poor surrogacy of Gynecologic Cancer Intergroup (GCIG) defined CA-125 response in recurrent ovarian cancer (ROC) patients. Mathematical modeling may help describe CA-125 decline dynamically and discriminate prognostic kinetic parameters. METHODS Data from CALYPSO phase III trial comparing 2 carboplatin-based regimens in ROC patients were analyzed. Based on population kinetic approach, serum [CA-125] concentration-time profiles during first 50 treatment days were fit to a semi-mechanistic model with following parameters: "d[CA-125]/dt=(KPROD∗exp (BETA∗t))∗Effect-KELIM∗[CA-125]" with time, t; tumor growth rate, BETA; CA-125 tumor production rate, KPROD; CA-125 elimination rate, KELIM and K-dependent treatment indirect Effect. The predictive values of kinetic parameters were tested regarding progression-free survival (PFS) against other reported prognostic factors. RESULTS Individual CA-125 kinetic profiles from 895 patients were modeled. Three kinetic parameters categorized by medians had predictive values using univariate analyses: K; KPROD and KELIM (all P<0.001). Using Cox multivariate analysis, 5 independent predictors of PFS remained significant: GCIG CA-125 response (favoring carboplatin-paclitaxel arm), treatment arm, platinum free-interval, measurable lesions and KELIM (HR=0.53; 95% CI 0.45-0.61; P<0.001). CONCLUSIONS Mathematical modeling of CA-125 kinetics in ROC patients enables understanding of the time-change components during chemotherapy. The contradictory surrogacy of GCIG-defined CA-125 response was confirmed. The modeled CA-125 elimination rate KELIM, potentially assessable in routine, may have promising predictive value regarding PFS. Further validation of this predictive marker is warranted.

Abstract
This paper proposes and demonstrates a framework for Sigma-Pi networks such that the combinatorial increase in product terms is avoided. This is achieved by only implementing a subset of the possible product terms (sub-net Sigma-Pi). Application of a dynamic weight pruning algorithm enables redundant weights to be removed and replaced during the learning process, hence permitting access to a larger weight space than employed at network initialization. More than one learning rate is applied to ensure that the inclusion of higher order descriptors does not result in over description of the training set (memorization). The application of such a framework is tested using a problem requiring significant generalization ability. Performance of the resulting sub-net Sigma-Pi network is compared to that returned by optimal multi-layer perceptrons and general Sigma-Pi solutions.

Abstract
OBJECTIVE To evaluate the extent and determinants of missed prenatal detection of congenital heart disease (CHD) in a population-based setting. METHODS This was a retrospective cohort study of cases with CHD, excluding minor defects, identified between 1997 and 2007 by a statewide surveillance program. We examined a comprehensive list of potential risk factors for which data were available in the surveillance database from abstracted medical charts. We analyzed the association of fetal, maternal and encounter factors with 1) whether a prenatal ultrasound was performed and 2) prenatal detection of CHD. RESULTS CHD was detected prenatally in only 39% of 1474 cases, with no improvement in detection rate over the 10-year period. Among the 97% (n = 1431) of mothers who underwent one or more ultrasound examinations, 35% were interpreted as abnormal; fetal echocardiography was performed in 27% of the entire cohort. Maternal and encounter factors increasing the adjusted odds of prenatal detection included: family history of CHD (OR, 4.3 (95% CI, 1.9-9.9)), presence of extracardiac defects (OR, 2.7 (95% CI, 1.9-3.9)) and ultrasound location i.e. high risk clinic vs clinic (OR, 2.1 (95% CI, 1.3-3.1)). Defects that would be expected to have an abnormal outflow-tract view were missed more often (64%) than were those that would be expected to have an abnormal four-chamber view (42%). CONCLUSION The majority of CHD cases over the 10-year study period were missed prenatally and detection rates did not increase materially during that time. The failure to detect CHD prenatally was related to encounter characteristics, specifically involving screening ultrasound examinations, which may be targeted for improvement.

Abstract
High-grade serous carcinoma (HGSC) is the most common and lethal subtype of ovarian cancer. Research over the past decade has strongly suggested that "ovarian" HGSC arises in the epithelium of the distal fallopian tube, with serous tubal intraepithelial carcinomas (STICs) being detected in 5-10% of BRCA1/2 mutation carriers undergoing risk-reducing surgery and up to 60% of unselected women with pelvic HGSC. The natural history, clinical significance, and prevalence of STICs in the general population (ie, women without cancer and not at an increased genetic risk) are incompletely understood, but anecdotal evidence suggests that these lesions have the ability to shed cells with metastatic potential into the peritoneal cavity very early on. Removal of the fallopian tube (salpingectomy) in both the average and high-risk populations could therefore prevent HGSC, by eliminating the site of initiation and interrupting spread of potentially cancerous cells to the ovarian/peritoneal surfaces. Salpingectomy may also reduce the incidence of the 2 next most common subtypes, endometrioid and clear cell carcinoma, by blocking the passageway linking the lower genital tract to the peritoneal cavity that enables ascension of endometrium and factors that induce local inflammation. The implementation of salpingectomy therefore promises to significantly impact ovarian cancer incidence and outcomes.

Abstract
GOAL The goal of this study was to evaluate a mindfulness-based cognitive behavioral intervention for sexual dysfunction in gynecologic cancer survivors compared to a wait-list control group. METHODS Thirty-one survivors of endometrial or cervical cancer (mean age 54.0, range 31-64) who self-reported significant and distressing sexual desire and/or sexual arousal concerns were assigned either to three, 90-minute mindfulness-based cognitive behavior therapy sessions or two months of wait-list control prior to entering the treatment arm. Validated measures of sexual response, sexual distress, and mood, as well as laboratory-evoked physiological and subjective sexual arousal were assessed at pre-, one month post-, and 6-months following treatment. RESULTS There were no significant effects of the wait-list condition on any measure. Treatment led to significant improvements in all domains of sexual response, and a trend towards significance for reducing sexual distress. Perception of genital arousal during an erotic film was also significantly increased following the intervention despite no change in physiologically-measured sexual arousal. CONCLUSIONS A brief mindfulness-based intervention was effective for improving sexual functioning. Geographic restrictions permitted only a select sample of survivors to participate, thus, the generalizability of the findings is limited. Future studies should aim to develop online modalities for treatment administration to overcome this limitation.

Abstract
Three large randomized clinical trials have shown a survival benefit in women with stage iii epithelial ovarian cancer (eoc) who receive intraperitoneal (IP) chemotherapy after optimal primary debulking surgery. The most recent Gynecologic Oncology Group study, gog 172, showed an improvement in median overall survival of approximately 17 months. That result led to a U.S. National Cancer Institute (nci) clinical announcement recommending that IP chemotherapy be considered for this group of women with eoc. However, IP chemotherapy is associated with increased toxicity, and rates for completion of treatment are low (42% in gog 172). The optimal IP regimen and duration of treatment has yet to be defined. Women undergoing chemotherapy before optimal debulking surgery were not included in the studies or in the nci clinical announcement. The National Cancer Institute of Canada Clinical Trials Group has developed a protocol for a randomized phase ii/iii study which will examine whether IP platinum-taxane-based chemotherapy benefits women who have received neoadjuvant chemotherapy before optimal surgical debulking. To address whether the less systemically toxic carboplatin can be substituted for cisplatin IP, the first phase of the study will have 3 arms: 1 intravenous-only, and 2 IP-containing regimens. At the end of the first stage, and provided that IP therapy is feasible to administer in this patient population, one of the IP regimens, either IP carboplatin or IP cisplatin, will proceed into a phase iii comparison with the intravenous arm. This exciting new study has gathered international support.

Abstract
OBJECTIVES To review the etiology and incidence of and associative factors in the formation of adhesions following gynaecological surgery. To review evidence for the use of available means of adhesion prevention following gynaecological surgery. OPTIONS Women undergoing pelvic surgery are at risk of developing abdominal and/or pelvic adhesive disease postoperatively. Surgical technique and commercial adhesion prevention systems may decrease the risk of postoperative adhesion formation. OUTCOMES The outcomes measured are the incidence of postoperative adhesions, complications related to the formation of adhesions, and further intervention relative to adhesive disease. EVIDENCE Medline, EMBASE, and The Cochrane Library were searched for articles published in English from 1990 to March 2009, using appropriate controlled vocabulary and key words. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, cohort studies, and meta-analyses specifically addressing postoperative adhesions, adhesion prevention, and adhesive barriers. Searches were updated on a regular basis and incorporated in the guideline to March 2009. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care.

Abstract
OBJECTIVE To formulate clinical recommendations for the assessment of endometrial thickening when it is found on ultrasound in a postmenopausal patient without bleeding. OUTCOMES Ensure that women with asymptomatic thickening and endometrial polyps found on ultrasound are managed appropriately. EVIDENCE Published literature was retrieved through searches of English language articles from the EMBASE, Cochrane, and PubMed databases for relevant peer-reviewed articles dating from 1970 to 2009, using appropriate controlled vocabulary (e.g., "asymptomatic endometrial thickness," "endometrial cancer," "postmenopausal bleeding," "transvaginal ultrasonography," "endometrial biopsy" and "endometrial polyp"). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Searches were updated on a regular basis and incorporated in the guideline to April 2010. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The level of evidence was determined according to the criteria established by the Canadian Task Force on Preventative Health Care (Table). Recommendations are ranked according to this method. BENEFITS, HARMS, AND COSTS It is anticipated that the adoption of these recommendations would save postmenopausal women unnecessary anxiety, pain, and risk of procedural complication. It is also expected to decrease the cost to the health system by eliminating unnecessary interventions.

Abstract
PURPOSE This randomized, multicenter, phase III noninferiority trial was designed to test the efficacy and safety of the combination of pegylated liposomal doxorubicin (PLD) with carboplatin (CD) compared with standard carboplatin and paclitaxel (CP) in patients with platinum-sensitive relapsed/recurrent ovarian cancer (ROC). PATIENTS AND METHODS Patients with histologically proven ovarian cancer with recurrence more than 6 months after first- or second-line platinum and taxane-based therapies were randomly assigned by stratified blocks to CD (carboplatin area under the curve [AUC] 5 plus PLD 30 mg/m(2)) every 4 weeks or CP (carboplatin AUC 5 plus paclitaxel 175 mg/m(2)) every 3 weeks for at least 6 cycles. Primary end point was progression-free survival (PFS); secondary end points were toxicity, quality of life, and overall survival. RESULTS Overall 976 patients were recruited. With median follow-up of 22 months, PFS for the CD arm was statistically superior to the CP arm (hazard ratio, 0.821; 95% CI, 0.72 to 0.94; P = .005); median PFS was 11.3 versus 9.4 months, respectively. Although overall survival data are immature for final analysis, we report here a total of 334 deaths. Overall severe nonhematologic toxicity (36.8% v 28.4%; P < .01) leading to early discontinuation (15% v 6%; P < .001) occurred more frequently in the CP arm. More frequent grade 2 or greater alopecia (83.6% v 7%), hypersensitivity reactions (18.8% v 5.6%), and sensory neuropathy (26.9% v 4.9%) were observed in the CP arm; more hand-foot syndrome (grade 2 to 3, 12.0% v 2.2%), nausea (35.2% v 24.2%), and mucositis (grade 2-3, 13.9% v 7%) in the CD arm. CONCLUSION To our knowledge, this trial is the largest in recurrent ovarian cancer and has demonstrated superiority in PFS and better therapeutic index of CD over standard CP.

Abstract
This article argues from a South African perspective that national experience in attempting to fulfil the right to health supports the need for an international framework. Secondly, we suggest that this framework is not just a matter of good choice or even of justice but of a direct legal duty that falls on those states that have consented to operate within the international human rights framework by ratifying key treaties such as the International Covenant on Economic Social and Cultural Rights (ICESCR), the Convention on the Elimination of all forms of Discrimination Against Women (CEDAW), and the Convention on the Rights of the Child (CRC). States can either accept this duty or face with growing pressure from those who believe in global social justice to find lasting solutions to the terrible inequities in global health standards.

Methods: Pts with recurrent OC > 6 months after first-line or second-line platinum-based therapy who had been pretreated with a taxane were randomized by stratified blocks to either C-D [C AUC 5 IV + PLD 30 mg/m2 IV] d1 q4 wk, or C-P [C AUC 5 IV + P 175 mg/m2 IV] d1 q3 wk × ≥ 6 cycles. The primary endpoint was progression-free survival (PFS), with secondary endpoints of toxicity, QoL and survival. The non-inferiority design required 745 events with 90% power, 95% confidence interval (CI). Results: From 4/05 to 09/07, 976 pts were enrolled, 467 to C-D arm and 509 to C-P arm. Pt parameters were well balanced. 85% of C-D and 78% of C-P pts received ≥ 6 cycles. Median follow-up is 21mo. Overall survival is still too early to be reported (n=308 deaths). This is the final analysis for PFS and toxicity. Results are below. Conclusions: This trial, the largest in relapsed OC, showed significant superiority of PLD-carboplatin combination in terms of PFS. In addition, compared to paclitaxel-carboplatin, PLD-carboplatin was well tolerated with lower rates of severe and long-lasting (neuropathy) toxicities.

Abstract
3005 Background: T-cell and antibody responses to self antigens on cancer are usually constrained by immunologic tolerance and ignorance. We found that DNA vaccines encoding xenogeneic differentiation antigens, such as tyrosinase (TYR), can mediate tumor protection and regression in implantable mouse models and dogs with spontaneously arising melanoma. Based on this, we conducted a trial of DNA vaccines encoding mouse and human TYR in patients with AJCC stage III/IV melanoma. Methods: HLA-A*0201+ melanoma patients were randomized to 2 different schedules: one group received 3 injections of mouse TYR DNA followed by 3 injections of human TYR DNA while the other group received 3 injections of human TYR DNA followed by 3 injections with the mouse gene. The study was conducted a three different dose levels: 100, 500 and 1,500 mcg DNA/injection, administered IM every 3 weeks. A total of 18 patients were treated, 6 at each dose level being randomized to one of the two schedules. Anti-TYR antibodies and CD8+ T cells recognizing the native human tyrosinase369-377 (YMDGTMSQV) peptide were measured at fixed time points. T-cell responses were monitored with MHC tetramer and intracytoplasmic IFN-γ staining assays using 10-day in vitro stimulation. Multiparametric flow cytometry was performed to further define the phenotype of responding cells. Results: Most toxicities were transient grade I injection site reactions. Seven patients had CD8+ T cell responses, defined as a >3 standard deviation increase in baseline reactivity to the TYR peptide in either the tetramer or intracellular IFN-γ assay. There was no relationship between dose level or assigned schedule and occurrence of T-cell response. Phenotypic characterization of responding T cells showed that most were consistent with an effector memory phenotype including the expression of granzyme B and surface expression of CD107a. No antibody responses were observed. At a median of 42 months of follow-up, median survival has not been reached and 6/18 patients have died from melanoma (1 in the group of patients who had a T cell response and 5 in the non-responders). Conclusions: Mouse and human TYR DNA vaccines were safe and induced CD8+ T cell responses in 7/18 patients. T cells recognizing a native TYR peptide had a phenotype consistent with that of effector memory cells. No significant financial relationships to disclose.

Abstract
BACKGROUND Comprehensive surgical staging of apparent early-stage epithelial ovarian cancer includes peritoneal washings, biopsies, and retroperitoneal lymph node dissection. Unresolved is the relative frequency or importance of the lymph node dissection. OBJECTIVES (1) To determine the site(s) of microscopic metastatic disease in women undergoing a comprehensive staging for apparent early-stage cancer of the ovary; (2) to identify those women with metastases in the retroperitoneal lymph nodes alone. METHODS Between 1985 and 2000, we reviewed all records of women at cancer centres in Winnipeg, Ottawa, and Saskatoon who had undergone a "staging laparotomy" for an apparent early-stage IA epithelial cancer of the ovary. Histology, tumour grade, initial and final surgical stage, and the site(s) of metastatic disease were recorded for all cases. RESULTS Forty-three of the 128 women (34%) had a final surgical stage of II or III. Sixteen women had positive pelvic biopsies, while 19 had microscopic upper abdominal disease. Eight women had positive retroperitoneal nodes, and in only 2 of these women, disease was found in the retroperitoneal nodes alone. In the 8 women with nodal disease, 5 had grade 3 tumours and 6 had serous histology tumours. CONCLUSION Comprehensive staging is important to identify women with metastatic disease. Solitary nodal metastases are predominantly found in grade 3 and serous tumours.

Abstract
Respect for and promotion of the human rights of people with HIV/AIDS is now an entrenched component of the global response to HIV. However, as the global HIV epidemic has turned into a global AIDS epidemic, and as the death toll mounts, one area of human rights—the right to health care—has become fiercely contested. In particular, the degree to which patents on medicines impede what the United Nations High Commissioner for Human Rights has described as the “human right” of access to essential medicines is receiving close scrutiny. The controversy generated by a recent article that argues, “in Africa patents and patent law are not a major barrier to treatment access in and of themselves,” is indicative of the intensity of the debate.

Abstract
A new stereophotolithography technique utilizing a spatial light modulator (SLM) to create three-dimensional components with a planar, layer-by-layer process of exposure is described. With this procedure it is possible to build components with dimensions in the range of 50 mum-50 mm and feature sizes as small as 5 mum with a resolution of 1 mum. A polysilicon thin-film twisted nematic SVGA SLM is used as the dynamic photolithographic mask. The system consists of eight elements: a UV laser light source, an optical shutter, beam-conditioning optics, a SLM, a multielement reduction lens system, a high-resolution translation stage, a control system, and a computer-aided-design system. Each of these system components is briefly described. In addition, the optical characteristics of commercially available UV curable resins are investigated with nondegenerate four-wave mixing. Holographic gratings were written at a wavelength of 351.1 nm and read at 632.8 nm to compare the reactivity, curing speed, shrinkage, and resolution of the resins. These experiments were carried out to prove the suitability of these photopolymerization systems for microstereolithography.
