Background: To investigate any associations between new clinical policies implemented because of the COVID-19 pandemic and harm to patients. Methods: Retrospective data collection of incidents and complaints reported through Datix®, and the Patient Advice and Liaison Service (PALS), respectively. The setting was the Family Health division in a University teaching hospital in the UK. Primary and secondary outcome measures included: the proportion of incidents reported on Datix® from 23 March 2020 to 29 May 2020, compared to the period from 23 March 2019 to 29 May 2019. COVID-19 related incidents and complaints and association with newly published guidelines or pathways from 23 March 2020 to 29 May 2020 were investigated. Results: There was no significant difference in the proportion of overall patient activity resulting in incidents reported on Datix in 2020 (2.08%) compared to 2019 (2.09%), with 98% resulting in no/low harm in 2020. Three incident categories had increases in relative proportions of incidents including the terms “COVID” or “Corona” compared to incidents that did not: “Child death”, “delay/failure to treatment and procedure” and “information governance”. One of the child deaths was a miscarriage and we were unable to link the second child death to a change in clinical policy at this stage. We were only able to link two COVID-19 associated incidents with a pathway or procedural change (one to the Children’s Emergency Department admission pathway and the second to the introduction of virtual antenatal clinics). Eighteen complaints related to COVID-19 were logged. However, at this stage, we are unable to link any of these to a published change in clinical policy. Conclusions: New policies introduced in the division, during the COVID-19 pandemic were associated with similar rates of clinical incidents, when compared with the previous year. There were only two COVID-19-related incidents clearly related to a change in pathways and procedures. Continued surveillance and improved metrics for monitoring the impact of changes to pathways and procedures should be sought with the sustained presence of COVID-19 in clinical areas.

Continued surveillance and improved metrics for monitoring the impact of changes to pathways and procedures should be sought with the sustained presence of COVID-19 in clinical areas.

Women with polycystic ovary syndrome (PCOS) are more likely to develop endometrial cancer (EC). The molecular mechanisms which increase the risk of EC in PCOS are unclear. Derangements in lipid metabolism are associated with EC, but there have been no studies, investigating if this might increase the risk of EC in PCOS. This was a cross-sectional study of 102 women in three groups of 34 (PCOS, EC and controls) at Nottingham University Hospital, UK. All participants had clinical assessments, followed by obtaining plasma and endometrial tissue samples. Lipidomic analyses were performed using liquid chromatography (LC) coupled with high resolution mass spectrometry (HRMS) and the obtained lipid datasets were screened using standard software and databases. Using multivariate data analysis, there were no common markers found for EC and PCOS. However, on univariate analyses, both PCOS and EC endometrial tissue samples showed a significant decrease in monoacylglycerol 24:0 and capric acid compared to controls. Further studies are required to validate these findings and investigate the potential role of monoacylglycerol 24:0 and capric acid in the link between PCOS with EC.

Background Transition into higher education has been identified as one of the most stressful periods for learners. Interventions targeting the transition phase such as near- peer mentoring might help address some of these challenges. We were however unable to identify a published systematic review of the literature describing outcomes of near-peer mentoring of medical students during the transition phase into medical school. The aim of this paper is to review the literature and describe the outcomes of near-peer mentoring schemes for first-year medical students in the transition phase. Methods A search of different electronic databases was carried out, using the search terms peer, buddy, mentor*, counsel*, advise*, tutor*, student, medical, school. 1861 articles were identified, however only 5 studies met the inclusion criteria- primary mentees should be first-years, and mentors must be inclusive of second-years but not limited to them. In reporting this paper, the PRISMA guidelines were followed. Results Published material on near-peer mentoring for medical students is scarce. Three outcomes for peer mentoring were identified- professional and personal development, stress reduction, and ease of transitioning. Incidentally, peer-mentoring was also found to have facilitated the development of personal and professional attitudes in the mentors. The quality of the evaluation methods in the studies was however low to moderate. Conclusion Near-peer-mentoring is a way of promoting professional and personal development. It is also promising to aid transition and maintain well-being of first-year medical students. However, larger, better quality longitudinal studies, are needed to ascertain its true value for these students.

Introduction Women with polycystic ovary syndrome have a three-fold higher risk of endometrial cancer. Insulin resistance and hyperlipidemia may be pertinent factors in the pathogenesis of both conditions. The aim of this study was to investigate endometrial sterol regulatory element binding protein-1 gene expression in polycystic ovary syndrome and endometrial cancer endometrium, and to correlate endometrial sterol regulatory element binding protein-1 gene expression with serum lipid profiles. Material and methods A cross-sectional study was performed at Nottingham University Hospital, UK. A total of 102 women (polycystic ovary syndrome, endometrial cancer and controls; 34 participants in each group) were recruited. Clinical and biochemical assessments were performed before endometrial biopsies were obtained from all participants. Taqman real-time polymerase chain reaction for endometrial sterol regulatory element binding protein-1 gene and its systemic protein expression were analyzed. Results The body mass indices of women with polycystic ovary syndrome (29.28 ± 2.91 kg/m2) and controls (28.58 ± 2.62 kg/m2) were not significantly different. Women with endometrial cancer had a higher mean body mass index (32.22 ± 5.70 kg/m2). Sterol regulatory element binding protein-1 gene expression was significantly increased in polycystic ovary syndrome and endometrial cancer endometrium compared with controls (p

BACKGROUND: Endometrial cancer is one of the most common gynaecological cancers in the world. Rates of endometrial cancer are rising, in part because of rising obesity rates. Endometrial hyperplasia is a precancerous condition in women that can lead to endometrial cancer if left untreated. Endometrial hyperplasia occurs more commonly than endometrial cancer. Progesterone tablets currently used to treat women with endometrial hyperplasia are associated with adverse effects in up to 84% of women. The levonorgestrel intrauterine device (Mirena Coil, Bayer HealthCare Pharmaceuticals, Inc., Whippany, NJ, USA) may improve compliance, but it is invasive, is not acceptable to all women, and is associated with irregular vaginal bleeding in 82% of cases. Therefore, an alternative treatment for women with endometrial hyperplasia is needed. Metformin, a drug that is often used to treat people with diabetes, has been shown in some human studies to reverse endometrial hyperplasia. However, the effectiveness and safety of metformin for treatment of endometrial hyperplasia remain uncertain. OBJECTIVES: To determine the effectiveness and safety of metformin in treating women with endometrial hyperplasia. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, Google Scholar, OpenGrey, Latin American Caribbean Health Sciences Literature (LILACS), and two trials registers from inception to 10 January 2017. We searched the bibliographies of all included studies and reviews on this topic. We also handsearched the conference abstracts of the European Society of Human Reproduction and Embryology (ESHRE) 2015 and the American Society for Reproductive Medicine (ASRM) 2015. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and cross‐over trials comparing metformin (used alone or in combination with other medical therapies) versus placebo or no treatment, any conventional medical treatment, or any other active intervention for women with histologically confirmed endometrial hyperplasia of any type. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for eligibility, extracted data from included studies, and assessed the risk of bias of included studies. We resolved disagreements by discussion or by deferment to a third review author. When study details were missing, review authors contacted study authors. The primary outcome of this review was regression of endometrial hyperplasia histology (with or without atypia) towards normal histology. Secondary outcome measures included recurrence of endometrial hyperplasia, progression of endometrial hyperplasia to endometrial cancer, hysterectomy rate, abnormal uterine bleeding, health‐related quality of life, and adverse effects during treatment. MAIN RESULTS: We included three RCTs in which a total of 77 women took part. We rated the quality of the evidence as very low for all outcomes owing to very serious risk of bias (associated with poor reporting, attrition, and limitations in study design) and imprecision. We performed a meta‐analysis of two trials with 59 participants. When metformin was compared with megestrol acetate in women with endometrial hyperplasia, we found insufficient evidence to determine whether there were differences between groups for the following outcomes: regression of endometrial hyperplasia histology towards normal histology (odds ratio (OR) 3.34, 95% confidence interval (CI) 0.97 to 11.57, two RCTs, n = 59, very low‐quality evidence), hysterectomy rates (OR 0.91, 95% CI 0.05 to 15.52, two RCTs, n = 59, very low‐quality evidence), and rates of abnormal uterine bleeding (OR 0.91, 95% CI 0.05 to 15.52, two RCTs, n = 44 , very low‐quality evidence). We found no data for recurrence of endometrial hyperplasia or health‐related quality of life. Both studies (n = 59) provided data on progression of endometrial hyperplasia to endometrial cancer as well as one (n = 16) reporting some adverse effects in the metformin arm, notably nausea, thrombosis, lactic acidosis, abnormal liver and renal function among others. Another trial including 16 participants compared metformin plus megestrol acetate versus megestrol acetate alone in women with endometrial hyperplasia. We found insufficient evidence to determine whether there were differences between groups for the following outcomes: regression of endometrial hyperplasia histology towards normal histology (OR 9.00, 95% CI 0.94 to 86.52, one RCT, n = 16, very low‐quality evidence), recurrence of endometrial hyperplasia among women who achieve regression (OR not estimable, no events recorded, one RCT, n = 8, very low‐quality evidence), progression of endometrial hyperplasia to endometrial cancer (OR not estimable, no events recorded, one RCT, n = 13, very low‐quality evidence), or hysterectomy rates (OR 0.29, 95% CI 0.01 to 8.37, one RCT, n = 16, very low‐quality evidence). Investigators provided no data on abnormal uterine bleeding or health‐related quality of life. In terms of adverse effects, three of eight participants (37.5%) in the metformin plus megestrol acetate study arm reported nausea. AUTHORS' CONCLUSIONS: At present, evidence is insufficient to support or refute the use of metformin alone or in combination with standard therapy ‐ specifically, megestrol acetate ‐ versus megestrol acetate alone, for treatment of endometrial hyperplasia. Robustly designed and adequately powered randomised controlled trials yielding long‐term outcome data are needed to address this clinical question.

Background: UK biobank was set up to investigate the respective contributions of genetic predisposition and environmental exposure to the development of disease and recruited participants between 2006 and 2010. Our aim was to investigate the feasibility of using UK biobank for exploring the association between polycystic ovarian syndrome (PCOS) and endometrial cancer, including the role played by serum IGF-1 levels. Methods: Publicly accessible and freely available online data in the resource section of the UK biobank website were used to determine the prevalence of self reported PCOS and for assessing the quality of data on ovarian imaging and serum biomarkers. A literature review was conducted to compare rates of PCOS in UK Biobank with other populations. Results: UK biobank contains 273,469 women (age range 37-73 years) of whom 643 (0.23%) self-reported PCOS. This was compared with values ranging from 3.1 % to 19.9% obtained from 16 studies picked up by our systematic literature search. Conclusion: It is feasible to use UK biobank to conduct research into the role of IGF-1 in explaining the association between PCOS and endometrial cancer. More detailed phenotyping of women recruited into the diagnostic group of PCOS is, however, vital to underpin this research. The resulting resource would be excellent for researchers interested in exploring the long-term health risks associated with PCOS.

The aim of this proof-of-concept study was to determine the effects of three-month Metformin therapy on the expression of tumor-regulatory genes (p53, cyclin D2 and BCL-2) in the endometrium of women with polycystic ovary syndrome (PCOS). A total of 40 women, aged between 21 and 45 years with PCOS (Rotterdam criteria) were recruited. The participants were assessed at pre- and 3-month-post-Metformin therapy for the menstrual regularities, weight reduction, Ferriman Galway scores, fasting blood glucose (FBG), total cholesterol, LDL, HDL and p53, BCL-2 and cyclin D2 gene expression. Five participants conceived spontaneously after the initial recruitment. Majority (68%) resumed regular menstrual cycles after Metformin. There were significant reduction in BMI (p = 0.001), weight (p = 0.001) and Ferriman Galway scores (p = 0.001). A significant improvement was seen in mean FBG (p = 0.002), total cholesterol (p = 0.001), LDL (p = 0.003) and HDL cholesterol levels (p = 0.015). Tumor suppressor gene (p53) was significantly up-regulated after Metformin (10 out of 14 women), with p value 0.016. BCL-2 and cyclin D2 (oncogenes) were slightly up-regulated without significant difference (p = 0.119 and 0.155, respectively). In conclusion, Metformin therapy improved clinical and metabolic parameters in women with PCOS and up-regulated p53 tumor suppressor gene significantly. Further studies are however required to independently validate our findings.

STUDY QUESTION Do any proteomic biomarkers previously identified for pre-eclampsia (PE) overlap with those identified in women with polycystic ovary syndrome (PCOS). SUMMARY ANSWER Five previously identified proteomic biomarkers were found to be common in women with PE and PCOS when compared with controls. WHAT IS KNOWN ALREADY Various studies have indicated an association between PCOS and PE; however, the pathophysiological mechanisms supporting this association are not known. STUDY DESIGN, SIZE, DURATION A systematic review and update of our PCOS proteomic biomarker database was performed, along with a parallel review of PE biomarkers. The study included papers from 1980 to December 2013. PARTICIPANTS/MATERIALS, SETTING, METHODS In all the studies analysed, there were a total of 1423 patients and controls. The number of proteomic biomarkers that were catalogued for PE was 192. MAIN RESULTS AND THE ROLE OF CHANCE Five proteomic biomarkers were shown to be differentially expressed in women with PE and PCOS when compared with controls: transferrin, fibrinogen α, β and γ chain variants, kininogen-1, annexin 2 and peroxiredoxin 2. In PE, the biomarkers were identified in serum, plasma and placenta and in PCOS, the biomarkers were identified in serum, follicular fluid, and ovarian and omental biopsies. LIMITATIONS, REASONS FOR CAUTION The techniques employed to detect proteomics have limited ability in identifying proteins that are of low abundance, some of which may have a diagnostic potential. The sample sizes and number of biomarkers identified from these studies do not exclude the risk of false positives, a limitation of all biomarker studies. The biomarkers common to PE and PCOS were identified from proteomic analyses of different tissues. WIDER IMPLICATIONS OF THE FINDINGS This data amalgamation of the proteomic studies in PE and in PCOS, for the first time, discovered a panel of five biomarkers for PE which are common to women with PCOS, including transferrin, fibrinogen α, β and γ chain variants, kininogen-1, annexin 2 and peroxiredoxin 2. If validated, these biomarkers could provide a useful framework for the knowledge infrastructure in this area. To accomplish this goal, a well co-ordinated multidisciplinary collaboration of clinicians, basic scientists and mathematicians is vital. STUDY FUNDING/COMPETING INTEREST(S) No financial support was obtained for this project. There are no conflicts of interest.

OBJECTIVE: Women with a prior history of polycystic ovary syndrome (PCOS) have an increased risk of endometrial cancer (EC).AIM: To investigate whether the endometrium of women with PCOS possess gene expression changes similar to those found in EC.DESIGN AND METHODS: Patients with EC, PCOS and control women unaffected by either PCOS or EC were recruited into a cross-sectional study at the Nottingham University Hospital, UK. For RNA sequencing, representative individual endometrial biopsies were obtained from women with EC, PCOS and a woman unaffected by PCOS or EC. Expression of a subset of differentially expressed genes identified by RNA sequencing, including NAD(P)H quinone dehydrogenase 1 (NQO1), were validated by quantitative reverse transcriptase PCR validation (n=76) and in the cancer genome atlas UCEC (uterine corpus endometrioid carcinoma) RNA sequencing dataset (n=381). The expression of NQO1 was validated by immuno-histochemistry in EC samples from a separate cohort (n=91) comprised of consecutive patients who underwent hysterectomy at St Mary's Hospital, Manchester between 2011 and 2013. A further 6 postmenopausal women with histologically normal endometrium who underwent hysterectomy for genital prolapse were also included. Informed consent and local ethics approval was obtained for the study.RESULTS: We show for the first that that NQO1 expression is significantly increased in the endometrium of women with PCOS and EC. Immunohistochemistry confirms significantly increased NQO1 protein expression in EC relative to non-malignant endometrial tissue (pCONCLUSIONS: The results obtained here support a previously unrecognized molecular link between PCOS and EC involving NQO1.

Women with polycystic ovary syndrome (PCOS) are at increased risk of developing insulin resistance and type 2 diabetes mellitus (T2DM). In this study, we attempted to list the proteomic biomarkers of PCOS and T2DM that have been published in the literature so far. We identified eight common biomarkers that were differentially expressed in both women with PCOS and T2DM when compared with healthy controls. These include pyruvate kinase M1/M2, apolipoprotein A-I, albumin, peroxiredoxin 2, annexin A2, α-1-B-glycoprotein, flotillin-1 and haptoglobin. These biomarkers could help improve our understanding of the links between PCOS and T2DM and could be potentially used to identify subgroups of women with PCOS at increased risk of T2DM. More studies are required to further evaluate the role these biomarkers play in women with PCOS and T2DM.

Introduction Endometrial hyperplasia is a precancerous lesion of the endometrium, commonly presenting with uterine bleeding. If managed expectantly, it frequently progresses to endometrial carcinoma, rates of which are increasing dramatically worldwide. However, the established treatment for endometrial hyperplasia (progestogens) involves multiple side effects and leaves the risk of recurrence. Metformin is the most commonly used oral hypoglycaemic agent in type 2 diabetes mellitus. It has also been linked to the reversal of endometrial hyperplasia and may therefore contribute to decreasing the prevalence of endometrial carcinoma without the fertility and side effect consequences of current therapies. However, the efficacy and safety of metformin being used for this therapeutic target is unclear and, therefore, this systematic review will aim to determine this. Methods and analysis We will search the following trials and databases with no language restrictions: Cochrane Gynaecology and Fertility Specialised Register; Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; EBSCO Cumulative Index to Nursing and Allied Health Literature; PubMed; Google Scholar; ClinicalTrials.gov; the WHO International Trials Registry Platform portal; OpenGrey and the Latin American and Caribbean Health Sciences Literature (LILACS). We will include randomised controlled trials (RCTs) of use of metformin compared with a placebo or no treatment, conventional medical treatment (eg, progestogens) or any other active intervention. Two review authors will independently assess the trial eligibility, risk of bias and extract appropriate data points. Trial authors will be contacted for additional data. The primary review outcome is the regression of endometrial hyperplasia histology towards normal histology. Secondary outcomes include hysterectomy rate; abnormal uterine bleeding; quality of life scores and adverse reactions to treatments. Ethics and dissemination Dissemination of the completed review will be through the Cochrane Library as well as through presenting the results at appropriate conferences.

Given the current lack of clarity in the published literature, we performed a systematic review of the literature to determine the exact strength of the association between polycystic ovary syndrome (PCOS) and endometrial cancer (EC).All published studies on the association between PCOS and EC identified through MEDLINE (1966-April 2011), EMBASE (1980-April 2011) and Cochrane (1998-April 2011). Original data were abstracted where available and summarized on a separate Microsoft Excel (2007) database for analysis. A total of 14 studies comparative and non-comparative were identified and included.The non-comparative and comparative data suggested that women with PCOS were more likely to develop EC. A meta-analyses of five comparative studies showed an increased risk of EC in women with an odds ratio of 2.89 with a 95% confidence interval of 1.52-5.48.Women with PCOS are about three times more likely to develop EC compared with women without it. This translates into a 9% lifetime risk of EC in Caucasian women with PCOS compared with 3% in women without it. Although most women (91%) with PCOS will not develop endometrial cancer, our study has shown that they are more likely at increased risk. More studies are required to clarify the exact molecular mechanisms, determine the best way of screening and preventing disease progression.

There is a need to identify biomarkers of impaired glucose tolerance (IGT) and type 2 diabetes mellitus (T2DM) risk in women with PCOS to facilitate screening and the development of novel strategies to prevent disease progression. Metabolomic technologies may address this need. All published studies on metabolomic biomarkers of IGT and/or T2DM identified through MEDLINE (1966-December 2010), EMBASE (1980-December 2010) and Cochrane (1993-December 2010) were retrieved. Eligible studies were screened and specific study characteristics recorded including study design, number of participants, selection criteria, type of metabolomic technique used, site of sample collection, and a list of metabolites identified to have been altered in IGT and/or T2DM versus healthy controls was created. Nine metabolomic biomarkers that could potentially be used to identify women with PCOS at risk of developing IGT and/or T2DM were identified including leucine, isoleucine, citrate, glucose, creatinine, valine, glutamine, alanine and HDL. Of these biomarkers, a panel of four biomarkers were consistently either elevated or reduced including glucose (elevated), valine (reduced), HDL (reduced) and alanine (reduced) in IGT/T2DM compared with controls. These biomarkers may predict the development of IGT/T2DM in young women with PCOS. More studies are required to test this hypothesis and translate the findings into patient benefit by reducing the morbidity/mortality associated with IGT/T2DM in PCOS.

BACKGROUND\ud \ud Endometrial cancer (EC) is the most common gynaecological cancer amongst women in the UK. Although previous studies have found that women with polycystic ovary syndrome (PCOS) have at least a three-fold increase in endometrial cancer (EC) risk compared to women without PCOS, the precise molecular mechanisms which link between PCOS and EC remain unclear. It has been suggested that insulin resistance may contribute to the increased risk of EC in PCOS. The specific expression of genes related to the insulin-signalling pathway including the IGF system in the endometrium of women with PCOS has however never been measured and compared to that in women with EC without PCOS and control women without EC or PCOS. .\ud \ud OBJECTIVES\ud \ud To test the hypothesis that insulin signaling plays a key role in the development of EC in women with PCOS by measuring and comparing the expression of three key genes involved in the insulin signaling pathway (IGF1, PTEN and IGFBP1) in endometrial tissue obtained from three groups of women; PCOS without EC, women with EC without PCOS and non-PCOS women without EC (controls). We also aimed to determine the correlation between the gene expressions to various clinical variables among participants.\ud \ud METHODS\ud \ud This was a cross-sectional study of 102 women in 3 groups (PCOS, EC and controls) at a University teaching hospital in the United Kingdom. Clinical assessment (blood pressure, body mass index (BMI) and waist-hip-circumference ratio), venepuntures (fasting blood sugar, insulin, lipid profile, hormones) and endometrial tissue biopsies were taken in all participants. Endometrial tissue RNA extraction was performed before real time polymerase-chain-reaction for the genes of interest (IGF1, IGFBP1 and PTEN) was carried out. To compare the baseline characteristics of the study population, One-Way-ANOVA test or the Independent t-test was used. For variables that were not normally distributed, the Spearman correlation test was used to calculate the r value. A "p" value of

The study objective was to investigate whether ultrasound (US) monitoring is essential during treatment with clomiphene citrate (CC) for ovulation induction, as recommended by the Royal College of Obstetricians and Gynaecologists (RCOG) and the National Institute for Clinical Excellence (NICE). We performed a systematic review of all studies investigating the effects of US in the treatment of ovulatory dysfunction with CC. The main objective of this review was to investigate whether US monitoring during CC treatment reduced multiple pregnancy rates. There was insufficient evidence to suggest that US monitoring reduces multiple pregnancy rates or improves pregnancy rates. On the other hand, no indication that treatment with CC is safe without US monitoring was identified. The small number of relevant studies and the heterogeneity observed in the methodologies of each study prohibit reliable conclusions to be drawn. There is currently no basis for amending the evidence base (good-practice points) used in the RCOG and NICE guidelines, which recommend the use of US to monitor the ovaries during stimulation with CC.

The aim of this study was to evaluate the number of surgeons required to successfully complete a range of gynaecological laparoscopic procedures using a new device (the Atiomo-Laparoscopic Assistant™), which enables one surgeon to easily simultaneously manipulate the uterus and the laparoscope. The number of surgeons required to complete the operation in 15 women undergoing a range of laparoscopic procedures using the Atiomo-Laparoscopic Assistant™ was compared with data retrospectively collected from theatre records. It was possible for one surgeon to assess the pelvis during laparoscopy in 10 (67%) of the 15 procedures where the Atiomo-Laparoscopic Assistant™ was used, compared with 177 of the 599 (30%) procedures where it was not used (p = 0.005). However, with the Mark 3 device, it was possible for one surgeon to perform the procedure in all seven procedures (100%) where it was used. Surgeons felt that the device was easy to use and no complications occurred.

Objective To identify the most commonly used methods for weight reduction in women with polycystic ovarian syndrome (PCOS) utilized by obstetricians and gynaecologists in the United Kingdom (UK). Study design Permission was sought from the Royal College of Obstetricians and Gynaecologists (RCOG) to conduct an electronic survey of all consultants practising in the UK. The questionnaire was anonymous and an electronic link was sent via email to the 1140 consultants whose details were provided by the RCOG. A 27-item questionnaire was developed. The variables evaluated were first-line methods of weight reduction used, proportion of women with PCOS seen that were obese, whether the patients had tried other weight reduction methods before seeking help, the optimal dietary advice and optimal composition, the optimal duration and frequency of exercise suggested, BMI used for suggesting weight loss, percentage of women in whom weight loss worked, length of time allowed prior to suggesting another method, methods considered most effective by patients, use of metformin for weight loss, criteria used for prescribing metformin, first-line anti-obesity drugs preferred if any, second- and third-line methods used, referral to other specialists and criteria for referral for bariatric surgery. Responses were categorical and are reported as proportions. Results One hundred and seven (9.4%) consultants responded to the questionnaire. One hundred and four (97%) provided advice on diet and 101 (94%) advice on exercise as their first-line strategy for weight management. Fifty-one (47.7%) stated that they provided specific information on an optimal dietary intake, 53 (49.9%) on the optimal dietary composition and 61 (57%) on the optimal duration and frequency of exercise per week. The commonest second-line methods used were anti-obesity drugs and metformin and the most popular third-line management options were anti-obesity drugs and bariatric surgery. Conclusions The results suggest that the information provided to women with PCOS on weight management is variable, and highlight the need for specific guidelines and further research on weight management in women with this condition.

Summary Objective Women with a prior history of polycystic ovary syndrome (PCOS) have an increased risk of endometrial cancer (EC). Aim To investigate whether the endometrium of women with PCOS possesses gene expression changes similar to those found in EC. Design and Methods Patients with EC, PCOS and control women unaffected by either PCOS or EC were recruited into a cross‐sectional study at the Nottingham University Hospital, UK. For RNA sequencing, representative individual endometrial biopsies were obtained from women with EC, PCOS and a woman unaffected by PCOS or EC. Expression of a subset of differentially expressed genes identified by RNA sequencing, including NAD(P)H quinone dehydrogenase 1 (NQO1), was validated by quantitative reverse transcriptase PCR validation (n = 76) and in the cancer genome atlas UCEC (uterine corpus endometrioid carcinoma) RNA sequencing data set (n = 381). The expression of NQO1 was validated by immunohistochemistry in EC samples from a separate cohort (n = 91) comprised of consecutive patients who underwent hysterectomy at St Mary's Hospital, Manchester, between 2011 and 2013. A further 6 postmenopausal women with histologically normal endometrium who underwent hysterectomy for genital prolapse were also included. Informed consent and local ethics approval were obtained for the study. Results We show for the first that NQO1 expression is significantly increased in the endometrium of women with PCOS and EC.

Objective Feasibility of a clinical-trial comparing a low-glycaemic diet with a low-calorie healthy eating approach at achieving weight loss and reducing the risk of endometrial cancer in women with PCOS. Design A pilot Randomised-Controlled-Trial using different recruitment strategies. Setting A University Hospital in the United Kingdom. Patients Women seen at specialist gynaecology clinics over a 12 month period in one University Hospital, and women self identified through a website and posters. Interventions Potential recruits were assessed for eligibility, gave informed consent, randomised, treated and assessed as in the definitive trial. Main outcome measures Eligibility and recruitment rates, compliance with the allocated diet for 6 months and with clinical assessments, blood tests, pelvic ultrasound scans and endometrial biopsies. Results 1433 new and 2598 follow up patients were seen in 153 gynaecology clinics for over 12 months. 441 (11%) potentially eligible women were identified, 19 (0.4%) of whom met the trial entry criteria. Eleven consented to take part, of which 8 (73%) completed the study. Conclusions Planned future trials on over-weight women with PCOS should be multicentre and should incorporate primary care. This data will help other researchers plan and calculate the sample size and potential recruitment rates in future clinical trials in PCOS. The results will also be useful for inclusion in future meta-analyses.

Objective To survey the preferences and variations in the current use of first- and second-generation endometrial ablative techniques for menorrhagia among the consultant gynecologists in the United Kingdom, given the call for further studies to systematically compare the clinical effectiveness of the various endometrial ablation techniques. Design Postal questionnaire survey. Population One thousand, four hundred sixty consultant gynecologists in the United Kingdom. Main Outcome Measure(s) Preferred endometrial ablation/resection method and variations in the current practices. Result(s) Six hundred ten (41%) consultants responded. Of these, 449 (73%) performed endometrial ablation/resection. Thermal balloon ablation (32.1%) was the preferred method, followed by microwave endometrial ablation (29.8%), transcervical resection of the endometrial alone or combined with roller ball diathermy (18.5%), Novasure (9.8%), hydrotherm ablation (6.9%), roller ball (2%), and laser (0.9%). Patient response to treatment was assessed using clinical history (64.3%), menstrual calendar (7.6%), clinical history and menstrual calendar (21.3%), questionnaires (5.8%), and pictorial blood loss assessment charts (0.4%). A total of 52.2% used gonadotrophin releasing hormone analogues preoperatively. Variations in techniques for transcervical resection of the endometrial included methods used to treat the uterine fundus and cornuae, fluid management, and operating pressures. Conclusion(s) Second-generation endometrial ablation devices were preferred to first-generation devices for the management of menorrhagia. Thermal balloon ablation was the most preferred method. However, variations in surgical practices will make assessment of clinical efficacy a challenge.

The aim of this study was to determine whether first-degree male relatives of women with polycystic ovary syndrome (PCOS) were at increased risk of cardiovascular disease (CVD) and diabetes mellitus (type II DM). In a cross-sectional study, 60 women with PCOS and 112 controls were given a questionnaire. The prevalence of heart disease, stroke, diabetes and associated risk factors among fathers and brothers of women with PCOS and controls, were measured. The percentage of women with PCOS with at least one brother with a risk factor for CVD was 47.5%, around twice that seen in control women (24.71%). The prevalence of heart disease, stroke and diabetes were similar in brothers of women with PCOS and controls. In conclusion, brothers of women with PCOS may be at increased risk of CVD. They form an easily identified group, which can be targeted for primary prevention.

Objective: To evaluate the current provision and outcome of community-based education (CBE) in UK medical schools. Design and data sources: An online survey of UK medical school websites and course prospectuses and a systematic review of articles from PubMed and Web of Science were conducted. Articles in the systematic review were assessed using Rossi, Lipsey and Freeman’s approach to programme evaluation. Study selection: Publications from November 1998 to 2013 containing information related to community teaching in undergraduate medical courses were included. Results: Out of the 32 undergraduate UK medical schools, one was excluded due to the lack of course specifications available online. Analysis of the remaining 31 medical schools showed that a variety of CBE models are utilised in medical schools across the UK. Twenty-eight medical schools (90.3%) provide CBE in some form by the end of the first year of undergraduate training, and 29 medical schools (93.5%) by the end of the second year. From the 1378 references identified, 29 papers met the inclusion criteria for assessment. It was found that CBE mostly provided advantages to students as well as other participants, including GP tutors and patients. However, there were a few concerns regarding the lack of GP tutors’ knowledge in specialty areas, the negative impact that CBE may have on the delivery of health service in education settings and the cost of CBE. Conclusions: Despite the wide variations in implementation, community teaching was found to be mostly beneficial. To ensure the relevance of CBE for ‘Tomorrow’s Doctors’, a national framework should be established, and solutions sought to reduce the impact of the challenges within CBE. Strengths and limitations of this study: This is the first study to review how community-based education is currently provided throughout Medical Schools in the UK. The use of Rossi, Lipsey and Freeman’s method of programme evaluation means that the literature was analysed in a consistent and comprehensive way. However, a weakness is that data from the online survey was obtained from online medical school prospectuses. This means the data may be incomplete or out of date. Data in the literature review may also be skewed by publication bias.

BACKGROUND: Women with polycystic ovary syndrome (PCOS) are assumed to be at increased risk of endometrial cancer (EC), albeit of a more differentiated type with better prognosis than in normal women. This study was designed to test these assumptions, as evidence for them is lacking. METHODS: The prevalence of polycystic ovaries (PCO), as a marker of PCOS, was investigated in ovarian sections from 128 women with EC and 83 with benign gynaecological conditions. The expression of the prognostic markers p53, Ki67, Bcl2 and cyclin D1 was also investigated by immunohistochemistry in endometrial tumours from 11 women with PCO and 16 with normal ovaries. RESULTS: Overall, PCO were similarly prevalent in women with EC (8.6%) and benign controls (8.4%); however, in women aged < 50 years, PCO were more prevalent in women with EC (62.5 versus 27.3%, P = 0.033). Cyclin D1-expressing endometrial tumours tended to be more prevalent in women with PCO compared to normal ovaries (36.4 versus 6.25%, respectively, P = 0.071). Bcl2-, p53- and Ki67-expressing tumours were similarly prevalent. CONCLUSIONS: The association between PCOS and EC appears confined to premenopausal women. The tendency for cyclin D1-expressing endometrial tumours to be more prevalent in women with PCO challenges the assumption that EC prognosis is improved in women with PCOS.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility and is conventionally treated with clomifene. Recent research shows that insulin resistance and hyperinsulinaemia lead to hyperandrogenism in PCOS. It is thought that this causes anovulation and infertility and is the rationale for the use of insulin-sensitising drugs such as metformin. This article explores the role of metformin, which is being increasingly used as first-line therapy to treat infertility with PCOS and potentially avoids the risks of multiple pregnancy and ovarian hyperstimulation associated with clomifene.

Polycystic ovary syndrome is one of the most common endocrine disorders in the human, affecting approximately 10% of women of reproductive age. Although originally considered a gynaecological disorder, the syndrome is associated with a wide range of endocrine and metabolic abnormalities, including insulin resistance. Affected women are at an increased risk of developing gestational and non-insulin dependent diabetes and there is an association with cardiovascular risk factors including obesity, hypertension, dyslipidaemia, hyperhomocysteinaemia, increased intima media thickness and impaired vascular elasticity. The effect on cardiovascular mortality is currently unclear. However, in view of the proven links with diabetes and the cardiovascular risk markers, this condition should be considered within the province of physicians as well as gynaecologists.

In 1935, a specific ovarian morphology of cystic and enlarged ovaries was described at laparotomy in seven women with obesity, amenorrhea or menstrual irregularity, hirsutism, and infertility. In several further studies in the 1950s and ‘70s, specific endocrine features of increased luteinizing hormone levels and hyperandrogenemia were described in these women. In the early ‘70s, with the availability of ultrasonography (US), noninvasive assessment of the ovaries was possible and, in 1985, a characteristic US appearance of polycystic ovaries was described. However, debate has remained concerning the correlation between the finding of polycystic ovaries on US and the clinical phenotype—some studies have shown that as many as 33% of apparently normal women will have polycystic ovaries. The etiology of polycystic ovary syndrome (PCOS) is also unknown. In 1935, Stein and Leventhal suggested a primary ovarian defect; however, more recently, a lot of interest has been focused on the role of insulin resistance as a common unifying hypothesis for the varied manifestation of this syndrome. Insulin resistance also has wider health implications such as diabetes, hypertension, and cardiovascular disease, and researchers are trying to quantify the risks of these conditions in PCOS. Therapy has evolved from a philosophy of primarily targeting the presenting clinical problem to ameliorating insulin resistance, which is now thought to be the primary defect. Improving insulin resistance has been shown to improve periods, fertility, and hyperandrogenemia. However, there remains some controversy as to the exact origin of this syndrome and it is still unknown which came first, “the insulin or the egg.”

Not all women with the polycystic ovary syndrome (PCOS) on ultrasound (US) will have the syndrome, and clinical and biochemical features of PCOS may be present without US features. The sensitivity of US in detecting PCOS was, therefore, prospectively determined in 72 women (32 PCOS and 40 controls). The most sensitive features were the presence of 10 or more follicles (82% and 69% in the left and right ovary) and a peripheral distribution of follicles (81.8% and 71.9% in the left and right ovary). Although ovarian enlargement and stromal brightness were not as sensitive as the previous criteria, stromal brightness was most specific. Combining all the criteria predicted a diagnosis of PCOS or control correctly in 86.4% of cases. This study shows that established US criteria of polycystic ovaries remain of value in the diagnosis of PCOS; however, the discrepancy between the left and right ovaries is an interesting but unexplained finding.

Current data indicate that there is a significant risk of endometrial cancer (EC) in women with polycystic ovarian syndrome (PCOS), although further research needed to clarify the exact molecular mechanisms. Endometrial hyperplasia is a premalignant condition that usually heralds EC and it shares identical risk factors with EC. Metabolic syndrome with a triad of obesity, hyperinsulinaemia and diabetes, which is commonly observed in PCOS appears to be a key mechanism in EC pathogenesis. Measures to improve insulin resistance could therefore play a role in reducing the risk of EC in women with PCOS. Metformin is an insulin sensitising agent which is safe, widely available and currently licensed for type-2 diabetes. It has been clearly shown in both animal and human studies that metformin is of value in reversing endometrial hyperplasia. Metformin may therefore prevent EC in PCOS. This article reviews the use of metformin in reducing EC risk in PCOS and makes a case for future research on this topic.

The aim of this study was to systematically review the evidence for the impact of scrotal cooling on spermatogenesis. EMBASE (1980-2010) and MEDLINE (1950-Sept. 2010) databases were searched using the terms 'male infertility or subfertility or fertility', combined with a separate search of 'scrotal cooling', without any limits or restrictions. A total of eight articles met the criteria for inclusion in the study. There was insufficient evidence to draw any firm conclusions about the impact of scrotal cooling on male fertility. A positive trend of improved male fertility was however observed. There is therefore a need for well designed randomised controlled trials.

Endometrial cancer (EC) is the commonest gynaecological cancer in North American and European women. Even though it has been shown that women with polycystic ovary syndrome (PCOS) have a three-fold increase in the risk of developing EC compared to women without PCOS, the precise molecular mechanisms which increase EC risk in women with PCOS remain unclear. Clinical strategies to prevent EC in PCOS are therefore not well researched and understood. Although raised estrogen levels, hyperinsulinaemia and, reduced apoptosis have been suggested as potential mechanisms, there is a lack of clarity about how these factors and other factors may interact to increase EC risk in PCOS. This article reviews the literature, on the potential molecular links between PCOS and EC but argues for a paradigm shift, to a systems biology-based approach in future research into the molecular links between PCOS and EC. The potential challenges of a systems biology-based approach are outlined but not considered insurmountable.

Objective To confirm whether there was a familial association between polycystic ovary syndrome (PCOS) and thromboembolic disease, ovarian or breast cancer, diabetes, and heart disease. Design Cross-sectional study. Setting A university hospital in the United Kingdom. Patient(s) Two hundred and seventeen women with and without PCOS under the care of the same consultant gynecologist at a teaching hospital. Intervention(s) Questionnaire survey. Main outcome measure(s) Prevalence of a personal or positive family history of thromboembolism, ovarian cancer, breast cancer, diabetes, and heart attacks. Result(s) In an analysis of the replies from 41 women with PCOS and 66 controls, we found a statistically significant positive family history of breast cancer and heart attacks among women with PCOS. There was no statistically significant difference in the mean age, ethnic origin, or prevalence of a family history of other diseases. Conclusion(s) Our results show a positive association between polycystic ovary syndrome and a family history of breast cancer and heart disease. These associations may be genetic in origin, or secondary to a complex interplay of genetic, intrauterine, and environmental factors. More studies are required to confirm these findings and determine the factors that explain these associations.

Background Male infertility is a significant contributor to the need for fertility treatment. Treatment currently involves correcting any identifiable adverse lifestyle factors in men with suboptimal sperm parameters, and if these measures are unsuccessful, assisted conception is offered, which can be quite expensive. Raised scrotal temperature is one of the least studied but easily corrected risk factors for male infertility. In a recent review of the literature, sperm count, motility and morphology improved with scrotal cooling devices. The devices used to achieve testicular cooling were, however, not practical for day-to-day use. A potentially more practical device for scrotal cooling has recently been developed. The Babystart® FertilMate™ Scrotum Cooling Patch is a hydrogel pad which allows for comfortable application. The aims of this study were to investigate whether exposing the scrotum to lower temperatures by means of these new patches could improve semen parameters, thereby improving fertility, and to assess the feasibility of a clinical trial. Methods/design This is a randomised controlled trial set in a university teaching hospital in the United Kingdom. The proposed sample size was 40 men with mild, moderate or severe oligoasthenospermia, of whom 20 would be randomised to wearing the scrotum cooling patch for 90 days and 20 men would be acting as controls and not wearing the patches. The primary outcome measure was the change in sperm concentration. Secondary outcome measures included the change in sperm volume, motility and morphology; endocrine parameters; metabolomic biomarkers; testicular volume and blood flow. Reasons for dropping out and non-compliance were also going to be noted and reported. Discussion The study started recruiting in October 2011 and as of November 2011 four men had been consented and were participating in the study. No operational challenges had been encountered at the time of the submission of this manuscript. Although the study also aimed to evaluate the feasibility of a definitive study, the change in sperm count after 90 days of wearing the scrotal cooling patches was made the primary outcome measure because a statistically significant improvement in sperm parameters with the scrotal patches would in itself be a definitive finding.

Objective To review and identify possible biomarkers for ovarian cancer (OC) in women with polycystic ovary syndrome (PCOS). Design Systematic literature searches of MEDLINE, EMBASE, and Cochrane using the search terms "proteomics," "proteomic," and "ovarian cancer" or "ovarian carcinoma." Proteomic biomarkers for OC were then integrated with an updated previously published database of all proteomic biomarkers identified to date in patients with PCOS. Setting Academic department of obstetrics and gynecology in the United Kingdom. Patient(s) A total of 180 women identified in the six studies. Intervention(s) Tissue samples from women with OC vs. tissue samples from women without OC. Main Outcome Measure(s) Proteomic biomarkers, proteomic technique used, and methodologic quality score. Result(s) A panel of six biomarkers was overexpressed both in women with OC and in women with PCOS. These biomarkers include calreticulin, fibrinogen-γ, superoxide dismutase, vimentin, malate dehydrogenase, and lamin B2. Conclusion(s) These biomarkers could help improve our understanding of the links between PCOS and OC and could potentially be used to identify subgroups of women with PCOS at increased risk of OC. More studies are required to further evaluate the role these biomarkers play in women with PCOS and OC.

Background A low Glycaemic Index (GI) diet may decrease some long-term health risks in Polycystic Ovary Syndrome (PCOS) such as endometrial cancer. This study was performed to assess compliance to a low GI diet in women with PCOS. Food diaries prospectively collected over 6 months from women on a low GI diet or healthy eating diet were analysed retrospectively. The women were recruited for a pilot randomised control trial investigating whether a low GI diet decreased the risk of Endometrial Cancer. Nine women with PCOS completed 33 food diaries (17 from women on a low GI diet and 16 from women on a healthy eating diet) recording 3023 food items (low GI group:n = 1457; healthy eating group:n = 1566). Data was analysed using Foster-Powell international values inserted into an SPSS database as no scientifically valid established nutrition software was found. The main outcome measures were mean item GI and Glyacemic Load (GL), mean meal GL, percentage high GI foods and mean weight loss. Findings Women allocated the low GI diet had a statistically significant lower GI of food items (33.67 vs 36.91, p < 0.05), lower percentage of high GI foods (4.3% vs 12.1%, p < 0.05) and lower GL of food items and meals. Conclusion Women with PCOS on a low GI diet consumed food items with a significantly lower mean GI and GL compared to the healthy eating diet group. Longer term compliance needs evaluation in subsequent studies to ascertain that this translates to reduced long term health risks. Trial Registration ISRCTN: ISRCTN86420258

The pathogenesis of polycystic ovary syndrome (PCOS) has been linked to the development of insulin resistance and hyperinsulinemia. The objective of this study is to investigate the effects of insulin sensitising agents such as D-chiro-inositol (DCI) on ovulation and insulin resistance in women with PCOS.This was a systematic review done in an Academic Department of Obstetrics and Gynaecology in the UK of all studies published on PCOS and DCI up till May 2010. Patients were women with PCOS receiving DCI or where the relationship between insulin resistance and DCI had been investigated. Ovulation rates and changes in insulin sensitivity were the main outcome measures.Less DCI-IPG was released in PCOS women compared to controls and this seems to correlate positively with insulin resistance and hyperinsulinemia evident in these patients. DCI administration had beneficial effects on ovulation, anthropometric and metabolic markers in PCOS women by enhancing insulin. The effects of metformin in improving insulin action in PCOS women was achieved though the release of DCI-IPG mediators.Heterogeneity observed in the methodologies of each study, the scarcity of relevant studies and the small sample sizes used prohibit reliable conclusions to be drawn. Therefore, more studies must be conducted in the future to evaluate accurately the effects of DCI in PCOS.

Medical students attending a careers talk in obstetrics and gynaecology at Nottingham University were approached in this survey, to identify factors which influenced an early career choice in OG. We received 60 responses, giving a response rate of 83.3%. The positive factors that encouraged an early career choice of OG were: a positive undergraduate OG attachment; consultant and junior doctor role-models; a good mix of medicine and surgery; availability of hands-on opportunities and early career advice. The perception of long working hours was not a negative influence. Male medical students were put-off by the lack of opportunity to undertake pelvic examinations.

Background The exact causes of polycystic ovary syndrome (PCOS) are uncertain, and treatment could be improved. Discovery-based approaches like ‘proteomics’ may result in faster insights into the causes of PCOS and improved treatment. Objectives To identify the number and nature of proteomic biomarkers found in PCOS so far and to identify their diagnostic and therapeutic potential. Search strategy All published studies on proteomic biomarkers in women with PCOS identified through the MEDLINE (1966–2008), EMBASE (1980–2008) and the ISI web of knowledge (v4.2) databases. Selection criteria The terms ‘polycystic ovary syndrome’ and ‘proteomic’, ‘proteomics’, ‘proteomic biomarker’ or ‘proteomics biomarker’ without any limits/restrictions were used. Data collection and analysis Original data were abstracted where available and summarised on a separate Microsoft Excel (2007) database for analysis. Main results Seventeen articles were identified, of which 6 original papers and 1 review article contained original data. Tissues investigated included serum, omental biopsies, ovarian biopsies, follicular fluid and T lymphocytes. Sample sizes ranged from 3 to 30 women. One hundred and forty-eight biomarkers were identified. The biomarkers were involved in many pathways, for example the regulation of fibrinolysis and thrombosis, insulin resistance, immunity/inflammation and the antioxidant pathway. Eleven groups of biomarkers appeared to be independently validated. The individual sensitivities for the diagnosis of PCOS were reported for 11 named biomarkers and ranged from 57 to 100%. Author’s conclusions Proteomic biomarker discovery in PCOS offers great potential. Current challenges include reproducibility and data analysis. The establishment of a PCOS-specific biomarker data bank and international consensus on the framework of systematic reviews in this field are required.

Summary Context An association between polycystic ovary syndrome (PCOS) and endometrial carcinoma was first suggested in 1949, 14 years after the original description of the syndrome. Since then several studies have been published that seem to support this association. The prescription of hormonal treatment to reduce the risk of this complication is supported by the Guidelines for Good Clinical Practice of the Royal College of Obstetricians and Gynaecologists, UK, the Health Information website of the National Library of Medicine, USA, and in textbooks of gynaecological oncology. Starting point A recent practice bulletin from the American College of Obstetricians and Gynecologists on the clinical management of PCOS ( Obstet Gynecol 2002; 100 : 1389–402) says that there is still no consensus on the "optimal progestin, duration and frequency of treatment to prevent endometrial cancer in women with PCOS". Chronic anovulation, obesity, and hyperinsulinaemia are all associated with PCOS as well as with endometrial carcinoma. It has been assumed that PCOS predisposes to endometrial cancer. However, the evidence for such an association is inconclusive. Although PCOS is associated with risk factors for endometrial cancer, it does not necessarily follow that the incidence or mortality from endometrial cancer is increased. Where next Large-scale studies of morbidity and mortality in unselected populations of women with PCOS are needed. Women with PCOS are increasingly aware of the possible risks, and it will be necessary to identify which of them, if any, are at increased risk and how this risk can be effectively reduced.

Objective: This study was performed to test the hypothesis that an increased prevalence of activated protein C (APC) resistance in women with polycystic ovary syndrome (PCOS) puts them at increased risk of miscarriage and thrombosis. Design: Case control study. Setting: A district general hospital in the United Kingdom. Patient(s): Forty-one women with PCOS and 25 controls. Intervention(s): Clinical histories, ultrasound scans, and venepunctures. Main Outcome Measure(s): Diagnosis of PCOS or control, clinical histories, APC resistance according to an activated partial thromboplastin time–based assay. Result(s): There was no significant difference in the proportion of women with APC resistance in both groups (three women in the PCOS group [7%] vs. one woman in the control group [4%]). The prevalence of APC resistance in the entire study population was 6.5%. In the PCOS group, 29% (12/41) gave a positive family history of thrombosis compared with 8% (2/25) in the control group. None of the women with a positive family history of thrombosis had abnormal antithrombin 111, protein C, or protein S levels. Conclusion(s): This study suggests that women with PCOS may have the same prevalence of APC resistance as the background population and that APC resistance may not put them at a higher risk of thrombosis or miscarriage compared with the case of the general population.
