Abstract
Abstract
Study question
Does fertility treatment (FT) increase the risk of recurrence of Borderline Ovarian Tumours (BOTs)?
Summary answer
There is a significant association between recurrence of BOTs and exposure to FT (p = 0.025).
What is known already
The association between pregnancy or controlled ovarian stimulation (COS) and risk of recurrence of BOTs is a controversial topic of interest amongst clinicians and women undergoing treatment. Some studies report a risk of non- invasive relapse following ovarian stimulation between 19.4-23%, whereas earlier case-control studies have shown no significant association.It is important to consider that most studies are limited by their retrospective analysis, with an emphasis on the incidence of primary BOTs following exposure to FT. Whereby, data regarding the risk of disease recurrence following spontaneous pregnancy (SP) or COS specifically, remains sparse.
Study design, size, duration
A retrospective cohort of women who underwent fertility sparing surgery (FSS) for the management of BOTs between the 1st January 2004 and 31st December 2020 at Imperial College Healthcare NHS Trust, with prospective follow up of reproductive outcomes and recurrence of disease following surgery.
Participants/materials, setting, methods
Subgroup analysis included a control group of all women not exposed to FT or SP and a non-control group of those who achieved either SP or underwent FT following FSS for the management of BOTs. The recurrence rate of BOTs was determined within each subgroup.
Main results and the role of chance
90 women underwent FSS for BOTs. Subgroup analysis confirmed 38.9% (35/90) were in the control group, 50% (45/90) in the non-control and 11.1% (10/90) lost to follow up. In the non-control group, 35.6% (16/45) achieved SP only and 64.4% (29/45) underwent FT. FT included COS for oocyte cryopreservation only (24.4%; 11/45), intracytoplasmic sperm insemination (ICSI) ± fresh or frozen embryo transfer (24.4%; 11/45) and those who underwent COS but also achieved SP without returning to their cryopreserved gametes (15.5%; 7/45). Within the non-control group, 75.6% (34/45) of women conceived, with a livebirth rate per pregnancy of 58.7% (27/46). The recurrence rate in the control and non-control groups were 20% (7/35) and 22.2% (10/45) respectively (p = 0.025) and 24.1% (7/29) following FT. Recurrence rates were 18.8% (3/16) after SP only, 0% (0/11) following oocyte cryopreservation only, 18.2% (2/11) ICSI ± embryo transfer and 71.4% (5/7) in those who underwent COS and achieved a SP. All recurrence of disease presented as serous BOTs. Within the FT group, logistic regression analysis demonstrated no significant predictors of disease recurrence. A combination of SP and FT is significantly associated with recurrence when compared to the following groups: control (p = 0.000), SP only (p = 0.001) and COS only (p = 0.015).
Limitations, reasons for caution
Due to the partial retrospective nature of the study, certain clinical information was not adequately documented and the subgroups compared were of unequal sample size, whilst overall sample size is also considered low. There was also a lack of control for confounders which may affect disease recurrence.
Wider implications of the findings
Despite the risk of recurrence of BOTs associated with FT, cases are often non invasive and successfully managed with further FSS with excellent prognosis. This evidence should be used to counsel women of reproductive age to ensure they can fulfil their reproductive aspirations, despite a diagnosis of BOT.

Abstract
OBJECTIVES At the end of 2020, many countries commenced a vaccination programme against SARS-CoV-2. Public health authorities aim to prevent and interrupt outbreaks of infectious disease in social care settings. We aimed to investigate the association between the introduction of the vaccination programme and the frequency and duration of COVID-19 outbreaks in Northern Ireland (NI). STUDY DESIGN We undertook an ecological study using routinely available national data. METHODS We used Poisson regression to measure the relationship between the number of RT-PCR confirmed COVID-19 outbreaks in care homes, and as a measure of community COVID-19 prevalence, the Office for National Statistics COVID-19 Infection Survey estimated the number of people testing positive for COVID-19 in NI. We estimated the change in this relationship and estimated the expected number of care home outbreaks in the absence of the vaccination programme. A Cox proportional hazards model estimated the hazard ratio of a confirmed COVID-19 care home outbreak closure. RESULTS Care home outbreaks reduced by two-thirds compared to expected following the introduction of the vaccination programme, from a projected 1625 COVID-19 outbreaks (95% prediction interval 1553-1694) between 7 December 2020 and 28 October 2021 to an observed 501. We estimated an adjusted hazard ratio of 2.53 of the outbreak closure assuming a 21-day lag for immunity. CONCLUSIONS These findings describe the association of the vaccination with a reduction in outbreak frequency and duration across NI care homes. This indicates probable reduced harm and disruption from COVID-19 in social care settings following vaccination. Future research using individual level data from care home residents will be needed to investigate the effectiveness of the vaccines and the duration of their effects.

Abstract
Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder amongst women of reproductive age, whose aetiology remains unclear. To improve our understanding of the molecular mechanisms underlying the disease, we conducted a genome-wide DNA methylation profiling in granulosa lutein cells collected from 16 women suffering from PCOS, in comparison to 16 healthy controls. Samples were collected by follicular aspiration during routine egg collection for IVF treatment. Study groups were matched for age and BMI, did not suffer from other disease and were not taking confounding medication. Comparing women with polycystic versus normal ovarian morphology, after correcting for multiple comparisons, we identified 106 differentially methylated CpG sites with p-values <5.8 × 10-8 that were associated with 88 genes, several of which are known to relate either to PCOS or to ovarian function. Replication and validation of the experiment was done using pyrosequencing to analyse six of the identified differentially methylated sites. Pathway analysis indicated potential disruption in canonical pathways and gene networks that are, amongst other, associated with cancer, cardiogenesis, Hedgehog signalling and immune response. In conclusion, these novel findings indicate that women with PCOS display epigenetic changes in ovarian granulosa cells that may be associated with the heterogeneity of the disorder.

Abstract
INTRODUCTION Aberrant function of granulosa cells has been implicated in the pathophysiology of PCOS. MATERIALS & METHODS Granulosa lutein (GL) cells were collected during oocyte retrieval for IVF/ICSI. RT-qPCR was used to compare gene expression between 12 control women, 12 with ovulatory PCO and 12 with anovulatory PCOS. To examine which genes are directly regulated by androgens, GL cells from an additional 12 control women were treated in-vitro with 10 nM dihydrotestosterone (DHT). RESULTS GL cells from women with PCOS showed reduced expression of CYP11A1 3-fold (p = 0.005), HSD17B1 1.8-fold (p = 0.02) and increased expression of SULT1E1 7-fold (p = 0.0003). Similar results were seen in ovulatory women with PCO. GL cells treated with 10 nM DHT showed a 4-fold (p = 0.03) increase in expression of SULT1E1 and a 5-fold reduction in SRD5A1 (p = 0.03). CONCLUSIONS These findings support the notion that aberrant regulation of steroid metabolism or action play a part in ovarian dysfunction in PCOS.

Abstract
OBJECTIVE To assess the impact of non-cavity-distorting fibroids on in vitro fertilisation (IVF) pregnancy outcomes. DESIGN A retrospective, matched, single-centre, cohort study was performed. SETTING The IVF unit of a tertiary, university hospital. POPULATION We analysed all women with non-cavity-distorting uterine fibroids undergoing IVF/intracytoplasmic sperm injection (ICSI) cycles from 1 January 2011 to 1 May 2015. METHODS Each woman was matched with two separate controls of the same age (±6 months), stimulation protocol (gonadotropin-releasing hormone agonist or antagonist), starting dose of follicle-stimulating hormone (FSH), number of embryos transferred (one or two), day of transfer (day 3 or day 5), and no uterine fibroids identified by transvaginal ultrasound. MAIN OUTCOME MEASURES Clinical pregnancy and live birth rates. RESULTS Our study demonstrates that the presence of non-cavity-distorting fibroids appears to negatively affect clinical pregnancy (odds ratio, OR 0.62; 95% confidence interval, 95% CI 0.41-0.94) and live birth rates (OR 0.58; 95% CI 0.48-0.78) in patients undergoing their first IVF/ICSI cycle, when matched with controls of the same age, starting dose of FSH, stimulation protocol, number of embryos, and day of embryo transfer. The deleterious effect of fibroids on live birth rates was significant in women with two or more fibroids (OR 0.47; 95% CI 0.26-0.83) and in women with fibroids of ≥30 mm in diameter (OR 0.41; 95% CI 0.19-0.89). The negative impact of non-cavity-distorting fibroids was also present in women with an embryo transfer on day 5 (OR 0.58; 95% CI 0.35-0.94). Conversely, in women with single fibroids of <30 mm in diameter, no difference in pregnancy outcomes was identified. CONCLUSIONS A well-designed, adequately powered, randomised controlled trial is required to address the role of medical or surgical interventions in patients with intramural and subserosal fibroids before undergoing fertility treatment. TWEETABLE ABSTRACT Non-cavity-distorting fibroids negatively affect pregnancy rates after IVF.

Abstract
STUDY QUESTION How do young women, who were identified as carrying a BRCA gene mutation before they had children, approach reproductive decision-making and what are their attitudes towards reproductive genetic testing? SUMMARY ANSWER Reproductive decision-making within the context of cancer risk is complex and influenced by personal experiences of cancer. Younger women were not concerned with reproductive decision-making at the time of their genetic test; however, the impact on subsequent reproductive decision-making was considerable and left them with unanticipated dilemmas, such as having children who would be at risk of inheriting cancer predisposition, timing risk-reducing surgery and changing perceptions of responsibility. WHAT IS KNOWN ALREADY Individuals carrying gene mutations predisposing to hereditary breast/ovarian cancer have concerns about passing on the gene mutation to children. STUDY DESIGN, SIZE, DURATION Qualitative methodology and thematic analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS Data were collected through semi-structured interviews with 25 women aged 18-45 who had received a positive result for a BRCA1 or BRCA2 gene mutation while childless. MAIN RESULTS AND THE ROLE OF CHANCE Analysis revealed four central themes: (i) the impact of cancer on reproductive decision-making; (ii) motivation for genetic testing; (iii) risk management and timing of planning children; and (iv) optimism for future medical advancements. LIMITATIONS, REASONS FOR CAUTION This study explores the views of female BRCA carriers. Further research should explore the views of couples, men, and include samples with greater ethnic and social diversity. WIDER IMPLICATIONS OF THE FINDINGS This evidence highlights the need for reproductive decision-making to be addressed at the time of pretest genetic counselling. More information should be provided on reproductive options as well as counselling/support to guide women's reproductive decision-making and prenatal testing options at the time they undertake genetic testing. STUDY FUNDING/COMPETING INTEREST(S) This research was supported by Cancer Research UK (Number C1226 A7920) and NIHR support to the Biomedical Research Centre at The Institute of Cancer Research and RMH. The authors have no conflicts of interest to declare. TRIAL REGISTRATION NUMBER Not applicable.

Abstract
The increasing sensitivity of PCR has meant that in the last two decades PCR has emerged as a major tool in diet studies, enabling us to refine our understanding of trophic links and to elucidate the diets of predators whose prey is as yet uncharacterized. The achievements and methods of PCR-based diet studies have been reviewed several times, but here we review an important development in the field: the use of PCR enrichment techniques to promote the amplification of prey DNA over that of the predator. We first discuss the success of using group-specific primers either in parallel single reactions or in multiplex reactions. We then concentrate on the more recent use of PCR enrichment techniques such as restriction enzyme digests, peptide nucleic acid clamping, DNA blocking and laser capture microdissection. We also survey the vast literature on enrichment techniques in clinical biology, to ascertain the pitfalls of enrichment techniques and what refinements have yielded some highly sensitive methods. We find that while there are several new approaches to enrichment, peptide nucleic acid clamping and DNA blocking are generally sufficient techniques for the characterization of diets of predators and highlight the most important considerations of the approach.

Abstract
The following is a review of a satellite symposium held at the EHRS Meeting in June 2006. U.B.P. reminded the audience that unwanted facial hair (UFH) is an important issue; over 40% of the women in the general population have some degree of UFH, and its psychological and psychosocial impact should not be underestimated. The treatment of UFH involves many different disciplines, and the symposium offered the latest thinking in different aspects of the disorder. S.L. outlined the current concepts surrounding polycystic ovarian syndrome, and U.G. addressed the psychological aspects of UFH. J.S. described the current treatment options for UFH, followed by U.B.P.'s evidence-based therapy review. Finally, R.H. reviewed the latest trial results with Trichoscan, a method being investigated for assessing UFH removal.

Abstract
Our aim was to compare a gonadotrophin-releasing hormone (GnRH) antagonist protocol with an analogue protocol using high dose gonadotrophins (rFSH) in women with poor ovarian response in order to optimise the management while undergoing assisted reproduction treatment. We recruited 31 consecutive patients over 5 months. The eligibility criteria for the study were: one or more previous cancelled cycle due to <or=3 follicles on day of hCG, or a total of >or=4,500 IU of rFSH. For the antagonist cycle regimen, we used daily 300 IU of rFSH from day 2 on the menses, and then from day 5 daily 0.25 mg of Cetrorelix until the day of human chorionic gonadotrophin (hCG) administration. We demonstrated that the use of an antagonist cycle was associated with a reduction in cancellation rates from 48% (agonist) to 10% (antagonist) (p < 0.039) allowing women to undergoing oocyte retrieval and embryo transfer with a non-significant improvement in the pregnancy rates.

Abstract
BACKGROUND Serum progesterone has been advocated as a tool in the diagnosis of early pregnancy failure. We conducted this prospective study in order to investigate the potential value of early (14 days after oocyte recovery) serum progesterone measurement, in women undergoing IVF/ICSI and receiving rectal progesterone supplements, in relation to pregnancy outcome. METHODS 442 women consecutively treated by IVF or ICSI had serum progesterone and bhCG levels prospectively measured 14 days after oocyte retrieval (day 0). All women received natural progesterone 400 mg rectally until the pregnancy test on day 14. Pregnant women were followed up by serial transvaginal ultrasound scans to 8 weeks gestation. RESULTS 115 women (26%) had a viable intra-uterine pregnancy at 8 weeks gestation, 80 (18.1%) had an abnormal pregnancy (biochemical, ectopic, miscarriage) and 247 (55.9%) failed to conceive. Women with on-going pregnancies had significantly higher serum progesterone levels (median: 430, 95%CI: 390-500 nmol/l) compared to those who had either an abnormal pregnancy (72, 48-96 nmol/l; P < 0.001) or failed to conceive (33, 28-37 nmol/l; P < 0.001). Receiver-operator curve analysis demonstrated that a single serum progesterone on day 14 post-oocyte retrieval, could highly differentiate between normal and abnormal pregnancies (area under the curve = 0.927, 95%CI = 0.89-0.96; P < 0.0001). CONCLUSIONS In spite of exogenous progesterone supplementation, serum progesterone levels, from as early as 4 weeks gestation (day 14 post-oocyte retrieval) were significantly elevated and predicted women destined to have viable intra-uterine pregnancies. These high levels are suggestive that endogenous progesterone is already sufficient in viable pregnancies and that exogenous progesterone administration will not rescue a pregnancy destined to result in a miscarriage. Single serum progesterone measurement could be a useful indicator of pregnancy outcome in women undergoing IVF or ICSI treatment.

Abstract
Preimplantation genetic diagnosis for haemophilia offers couples at risk for transmitting the condition the opportunity to embark on a pregnancy knowing that the embryo is unaffected by the disease. The technique aims to increase the range of reproductive options available to these couples and remove the need for invasive prenatal diagnosis and the difficult decision on whether to terminate an affected pregnancy. This aims to reduce the anxiety associated with reproduction often seen in these couples. Patients undergo a cycle of in vitro fertilization followed by embryo biopsy. The single blastomeres are then analysed using fluorescent in situ hybridization to detect the sex of the embryo, and only female embryos are transferred to the uterus. Recently a PCR based approach has allowed specific mutation detection, and therefore the transfer of unaffected male and female embryos.

Abstract
BACKGROUND The aim of this study was to determine whether there is evidence of a systemic maternal inflammatory response in very early pregnancy. METHODS Successive women receiving treatment by IVF or ICSI had serum C-reactive protein (CRP) levels measured on the day of their pregnancy blood test at 4 weeks gestation (14 days post-egg collection). Women with positive betaHCG levels had ongoing pregnancies confirmed by serial transvaginal ultrasound scans up to 8 weeks gestation. RESULTS Pregnant women (n = 40) were significantly younger (mean age 34 years) than women who failed to become pregnant (n = 95, mean age 37 years, P < 0.001), received significantly lower treatment doses of recombinant FSH (2000 versus 2400 IU, P < 0.05) and had significantly more eggs collected (11 versus 8, P < 0.01). There were no significant differences in body mass index, parity, a history of smoking, endometriosis or polycystic ovaries, pre-treatment CRP levels and white cell counts, peak serum estradiol levels and numbers of embryos transferred. Pregnant women had significantly higher CRP levels (median 3.68 mg/l) than those who were not pregnant (median 1.495 mg/l, P < 0.0001), a difference that persisted after excluding potential confounding variables. Six pregnant women with ovarian hyperstimulation syndrome had higher CRP levels than those who did not (P < 0.01). CONCLUSIONS This well-controlled study is the first to demonstrate that maternal CRP levels are raised as early as 4 weeks gestation and thus that the maternal inflammatory response is established during the earliest phases of implantation. It is hypothesized that an abnormal response (either exaggerated or absent) could cause some cases of miscarriage.

Abstract
DNA Surveillance is a Web-based application that assists in the identification of the species and population of unknown specimens by aligning user-submitted DNA sequences with a validated and curated data set of reference sequences. Phylogenetic analyses are performed and results are returned in tree and table format summarizing the evolutionary distances between the query and reference sequences. DNA Surveillance is implemented with mitochondrial DNA (mtDNA) control region sequences representing the majority of recognized cetacean species. Extensions of the system to include other gene loci and taxa are planned. The service, including instructions and sample data, is available at http://www.dna-surveillance.auckland.ac.nz.

Abstract
BACKGROUND It has been previously reported that a group of 12 infertile women, who had a normal baseline hormonal profile and did not respond to repeated ovarian stimulation with gonadotrophins, developed ovarian failure within a few months. Based on this observation, we carried out a controlled retrospective cohort study to examine whether non-response to ovarian stimulation is linked to early ovarian failure. METHODS All patients aged 35-40 years who had cancelled IVF cycles for non-response between 1991 and 1993 in our centre were asked to report on the subsequent development of menopausal symptoms, menopause or commencement of hormone replacement therapy. A control group consisted of patients with the same age and similar medical history, who had IVF the same year and responded well. RESULTS Eleven out of the 12 patients of the non-response group developed menopausal symptoms within 7 years, compared with only four out of 24 in the control group. Similarly, eight out of 12 non-responders either went into menopause or started using hormone replacement therapy compared with one out of 24 in the control group. Using Fisher's exact test, the differences were highly significant (P < 0.0001). The median age at development of menopausal symptoms in the study group was 40 years (range 38-45). The median time between non-response and development of menopausal symptoms was 4 years (range 1-7). CONCLUSION We carried out a controlled retrospective cohort study that showed a strong association between an extremely poor response to ovarian hyperstimulation and early ovarian failure.

Abstract
The repeated appearance of strikingly similar crab-like forms in independent decapod crustacean lineages represents a remarkable case of parallel evolution. Uncertainty surrounding the phylogenetic relationships among crab-like lineages has hampered evolutionary studies. As is often the case, aligned DNA sequences by themselves were unable to fully resolve these relationships. Four nested mitochondrial gene rearrangements--including one of the few reported movements of an arthropod protein-coding gene--are congruent with the DNA phylogeny and help to resolve a crucial node. A phylogenetic analysis of DNA sequences, and gene rearrangements, supported five independent origins of the crab-like form, and suggests that the evolution of the crab-like form may be irreversible. This result supports the utility of mitochondrial gene rearrangements in phylogenetic reconstruction.

Abstract
OBJECTIVE To compare the efficacy and efficiency of recombinant FSH (rFSH) and urinary FSH (uFSH). DESIGN Retrospective case controlled analysis. SETTING An assisted reproduction unit at a university center. PATIENT(S) 1388 patients undergoing long protocol in vitro fertilization/embryo transfer (IVF-ET) using buserelin acetate from day 2 of the cycle and either rFSH (follitropin beta) (n = 694) or uFSH (n = 694) with equal number of ampules started (rFSH: 50 IU, uFSH: 75 IU). INTERVENTION(S) Patients were included in the two groups of treatment after matching for similarity in age and type of treatment (IVF or intracytoplasmic sperm injection). MAIN OUTCOME MEASURE(S) Total dose of FSH, ovarian response, and IVF outcome. RESULT(S) Patients who received uFSH experienced a shorter period of stimulation, and a higher number of oocytes were collected. The total FSH used was lower in the rFSH group, and they required a lower FSH dose per oocyte retrieved. The implantation and pregnancy rates were similar between the uFSH and rFSH groups. In both groups implantation and pregnancy rates were higher when intracytoplasmic sperm injection was performed as compared with IVF. CONCLUSION(S) The implantation and pregnancy rates are similar when either rFSH or uFSH is used (when compared on an ampule-to-ampule basis, rFSH: 50 IU, and uFSH: 75 IU). However, a significantly lower total FSH dose was used in the rFSH group with a lower FSH dose per oocyte collected.

Abstract
The study was designed to examine whether dynamic measurements of inhibin B and oestradiol following single administration of buserelin acetate were correlated with the ovarian response to stimulation in IVF. A total of 37 patients undergoing IVF treatment was studied when the long protocol was started in the early follicular phase. Blood samples were taken twice: on day 2 of the menstrual cycle, before the first s.c. administration of buserelin acetate 0.5 mg and on day 3, 24 h later. Inhibin B and oestradiol concentrations were compared with the ovarian response to stimulation. The ovarian response was defined in two ways: 'number of oocytes/total recombinant (r) follicle stimulating hormone (FSH) dose'; and 'square-root (number of follicles/total rFSH dose)'. The following measurements were highly correlated with the ovarian response to stimulation: increase in oestradiol (day 3-day 2 oestradiol concentration) [correlation coefficient (r) = 0.68, P: < 0.0001] and sum of inhibin B (day 2 + day 3 inhibin B concentrations) (r = 0.6, P: < 0.0001). Age and basal concentrations of FSH and inhibin B were inferior to the above measurements in terms of correlation with the ovarian response. In conclusion, dynamic measurements of inhibin B and oestradiol following single administration of buserelin acetate were highly correlated with the ovarian response to stimulation for IVF treatment.

Abstract
OBJECTIVE To compare the following IVF protocols: a short protocol and long protocols starting on day 2 or day 21. All protocols used recombinant FSH (rFSH) for ovarian stimulation. DESIGN Prospective, randomized study. SETTING An assisted reproduction unit at a university center. PATIENT(S) Patients undergoing IVF (n = 150) were treated according to one of the three treatment protocols allocated by a random method. INTERVENTION(S) All patients used buserelin acetate and rFSH. Patients began the long protocol on day 2 (group 1) or day 21 (group 2) of the cycle. Patients in group 3 began the short protocol on day 2 of the cycle. MAIN OUTCOME MEASURE(S) Ovarian response, implantation rates, and pregnancy rates (PRs). RESULT(S) Patients treated with the short protocol (group 3) were stimulated in a shorter time, required less rFSH, and achieved higher E(2) levels. The numbers of follicles, oocytes, and embryos were similar in all three groups. The implantation rates were similar in groups 1 and 2 (11.8% and 13.3%, respectively), and both were higher than in group 3 (4.1%). Clinical PRs per oocytes retrieved were 19.6%, 18.6%, and 8.3% in groups 1, 2, and 3, respectively. CONCLUSION(S) The implantation rate was significantly higher with the long protocols than with the short protocol, with a tendency for a higher PR as well.
