RESUMEN
BACKGROUND: Women with polycystic ovary syndrome (PCOS) are usually told that the condition is associated with fertility difficulties. However, little is known about their fertility management including contraceptive use, childbearing desires, and pregnancy outcomes. AIM: To compare the fertility management experiences and outcomes of Australian women with and without PCOS. METHOD: The 2013 Australian electoral roll was used to identify a random sample of 18- to 50-year-old women who were sent the Understanding Fertility Management in Australia survey to be completed anonymously. Factors associated with fertility management and outcomes were identified in multivariable analyses. RESULTS: Among the 1543 women who completed and returned the survey, 113 (7.3%) reported having PCOS. Women with PCOS reported a similar rate of current contraceptive use as women without PCOS (50.4% vs. 52.6%, p = .66). However, they were significantly younger at first pregnancy (24.9 vs. 26.8 years, p = .015), more likely to have consulted a health professional about fertility management (OR: 3.86, 95% CI: 2.50-5.96, p < .001), and perceive that it would be difficult to conceive (OR: 2.31, 95% CI: 1.41-3.79, p = .001) than women without PCOS. There were no significant differences in the number of desired children, unintended pregnancies, live births, abortions or miscarriages between women with and without PCOS. CONCLUSION: These findings indicate that women with PCOS need more nuanced information about their fertility potential. While they may experience fertility difficulties because of their condition, they should also be informed that they can conceive spontaneously and need reliable contraception to avoid pregnancy when it is not wanted.

STUDY QUESTION: What are the reproductive experiences of women who cryopreserve oocytes for non-medical reasons? SUMMARY ANSWER: One in three women had been pregnant at some stage in their lives and while most still wanted to have a child or another child, very few had used their stored oocytes, predominantly because they did not want to be single parents. WHAT IS KNOWN ALREADY: The number of healthy women who freeze oocytes to avoid age-related infertility is increasing. Evidence about reproductive outcomes after oocyte cryopreservation for non-medical reasons is needed to help women make informed decisions. STUDY DESIGN SIZE, DURATION: A cross-sectional survey was carried out. Study packs which included a self-administered questionnaire were mailed by clinic staff to 193 eligible women. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women who had stored oocytes for non-medical reasons at Melbourne IVF, a private ART clinic, between 1999 and 2014 were identified from medical records and invited to complete an anonymous questionnaire about their reproductive histories and experience of oocyte cryopreservation. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 10 survey packs were returned to the clinic marked 'address unknown'. Of the 183 potential respondents, 96 (53%) returned the questionnaire. One respondent provided only free-text comments, thus data from 95 respondents were compiled. The mean age at the time of freezing oocytes was 37.1 years (SD ± 2.6, range: 27-42) and the average number of oocytes stored was 14.2 (SD ± 7.9, range: 0-42); 2% had attempted to store oocytes but had none suitable for freezing, 24% had stored <8 oocytes, 35% had 8-15, 25% had 16-23 and 14% had stored >23 oocytes. About one-third of respondents (34%) had been pregnant at some point in their lives. Six women (6%) had used their stored oocytes and three of them had given birth as a result. The main reason for not using stored oocytes was not wanting to be a single parent. Of the 87 (91%) women who still had oocytes stored, 21% intended to use them while 69% indicated that their circumstances would determine usage. The mean number of children respondents would ideally have liked to have was significantly higher than the number of children they expected to have (2.11 versus 1.38, P < 0.001). LIMITATIONS, REASONS FOR CAUTION: The limitations are inherent to any anonymously completed questionnaire: participation bias, missing data and the possibility that some questions or response alternatives may have been ambiguous. WIDER IMPLICATIONS OF THE FINDINGS: The findings add to the very limited evidence about the reproductive outcomes experienced by women who freeze oocytes for non-medical reasons and can be used to help women make informed decisions about whether to store oocytes.

Unintended pregnancy can be difficult to identify and conceptualise. We aimed to understand how unintended pregnancies are constructed, explained and situated in a reproductive life. A total of 41 women and 7 men aged 20-50 years were interviewed in depth. Transcripts were analysed using iterative hermeneutic techniques informed by narrative theory. Of 34 participants who had been pregnant or had a partner in pregnancy, 12 women and 1 man described 23 'unintended' pregnancies, about half of which ended in abortion. Their accounts reveal that an unintended pregnancy is identified subjectively, that the same pregnancy may be identified by one partner in the pregnancy as unintended and by the other as intended, and that a researcher's supposedly objective assessment of an unintended pregnancy may be inconsistent with the assessment of the woman who experienced it. A pejorative discourse was evident, predominantly among participants who did not report having an unintended pregnancy: women use an 'unintended' pregnancy to entrap men. Accounts from five participants reporting an unintended pregnancy were selected for illustration. An appreciation of the role such a pregnancy might play in an individual life requires a nuanced understanding of the complexity of human experience and a resistance to simple binary categorisation.

BACKGROUND: The introduction to Australia of modern medical abortion methods, which require less specialist expertise and equipment than the more traditional surgical methods, have brought an as yet unrealised potential to improve access to abortion services. AIMS: To investigate the potential for expanding the role of general practice in the provision of medical abortion in Victoria. MATERIALS AND METHODS: In 2015, in-depth interviews were conducted with 19 experts in abortion service provision in Victoria. A semi-structured interview schedule was used to guide the interviews. Interviews were transcribed verbatim and transcripts analysed thematically. RESULTS: Participants were largely very supportive of the provision of early medical abortion in general practice as a way of increasing abortion access for women, particularly in rural and regional communities. Access to abortion was seen as an essential component of women's comprehensive health care and therefore general practitioners (GPs) were perceived as ideally placed to provide this service. However, this would require development and implementation of new service models, careful consideration of GP and nurse roles, strengthening of partnerships with other health professionals and services in the community, and enhanced training, support and mentoring for clinicians. CONCLUSION: The application of these findings by relevant health services and agencies has the potential to increase provision of medical abortion services in general practice settings, better meeting the health-care needs of women seeking this service.

BACKGROUND: Depending on availability, many Australian women seeking an abortion will be faced with the choice between surgical or medical abortion. Little is known about the factors that influence Australian women's choice of method. AIM: Through the perspectives of abortion service providers, this study aimed to explore the factors that contribute to Australian women's decision to have a surgical or medical abortion. MATERIALS AND METHODS: In 2015, in-depth interviews were conducted with fifteen Victorian-based key informants (KIs) directly providing or working within a service offering medical abortion. Ten KIs were working at a service that also provided surgical abortion. Interviews were semi-structured, conducted face-to-face or over the telephone, transcribed verbatim and analysed thematically. RESULTS: KIs described varying levels of awareness of medical abortion, with poorer awareness in regional areas. When it comes to accessing information, women were informed by: their own research (often online); their own experiences and the experiences of others; and advice from health professionals. Women's reasons for choosing surgical or medical abortion range from the pragmatic (timing and location of the method, support at home) to the subjective (perceived risk, emotional impact, privacy, control, and physical ability). CONCLUSIONS: Women benefit from an alternative to surgical abortion and are well-placed to choose between the two methods, however, challenges remain to ensure that all women are enabled to make an informed choice. KIs identify the need to: promote the availability of medical abortion; address misconceptions about this method; and increase general practitioner involvement in the provision of medical abortion.

OBJECTIVES: The aim of this research was to investigate awareness, perceived reliability and consideration of use of long-acting reversible contraception (LARC) among Australians of reproductive age. METHODS: A sample of 18- to 50-year-old women and men (N = 2235) was randomly recruited from the Australian electoral roll in 2013. Respondents completed a self-administered, anonymous questionnaire. Data were weighted to reduce non-response bias. Factors associated with perceived reliability and consideration of use of LARC were identified in multivariable analyses. RESULTS: Most respondents had heard of implants (76.5%) and intrauterine contraception (63.7%). However, most did not think implants (56.3%) or IUDs (63.9%) were reliable and would not consider using implants (71.6%) or IUDs (77.5%). Those significantly more likely to perceive LARC as reliable were younger, did not regard religion as important in fertility choices, had private health insurance, had been pregnant and had had an abortion; and women who had a partner. Those more likely to consider using LARC were younger and did not regard religion as important in fertility choices; women who had private health insurance, lived in an area of socioeconomic advantage and had had an abortion; and men without a partner, born in Australia and comfortable talking to a health care provider about contraceptive matters. CONCLUSIONS: Despite high awareness of LARC among Australian adults, its perceived reliability and willingness to use it remain low in certain groups. Targeted interventions that aim to increase knowledge of the benefits and reliability of LARC and allow informed use are recommended.

The optimization of a novel series of non-nucleoside reverse transcriptase inhibitors (NNRTI) led to the identification of pyridone 36. In cell cultures, this new NNRTI shows a superior potency profile against a range of wild type and clinically relevant, resistant mutant HIV viruses. The overall favorable preclinical pharmacokinetic profile of 36 led to the prediction of a once daily low dose regimen in human. NNRTI 36, now known as MK-1439, is currently in clinical development for the treatment of HIV infection.

Antagonists to the human metabotropic glutamate receptor subtype 5a(mGluR(5a)) have been implicated as potential therapeutics for the treatment of a variety of nervous system disorders, including pain, anxiety, and Parkinson's disease. To discover novel antagonists to the mGluR(5a), a functional assay measuring agonist-induced intracellular calcium release was developed. The assay was used for the high-throughput screening of a large collection of compounds in single wells using a fully automated robotic platform. Primary high-throughput screening hits were subjected to a combination of data analysis and counterscreening assays to identify several compounds with both efficacy and selectivity for the metabotropic glutamate receptor target.
