RESUMEN
OBJECTIVE: Mechanisms of insulin resistance in polycystic ovary syndrome (PCOS) remain ill defined, contributing to sub-optimal therapies. Recognising skeletal muscle plays a key role in glucose homeostasis we investigated early insulin signalling, its association with aberrant transforming growth factor ß (TGFß)-regulated tissue fibrosis. We also explored the impact of aerobic exercise on these molecular pathways. METHODS: A secondary analysis from a cross-sectional study was undertaken in women with (n = 30) or without (n = 29) PCOS across lean and overweight BMIs. A subset of participants with (n = 8) or without (n = 8) PCOS who were overweight completed 12 weeks of aerobic exercise training. Muscle was sampled before and 30 min into a euglycaemic-hyperinsulinaemic clamp pre and post training. RESULTS: We found reduced signalling in PCOS of mechanistic target of rapamycin (mTOR). Exercise training augmented but did not completely rescue this signalling defect in women with PCOS. Genes in the TGFß signalling network were upregulated in skeletal muscle in the overweight women with PCOS but were unresponsive to exercise training except for genes encoding LOX, collagen 1 and 3. CONCLUSIONS: We provide new insights into defects in early insulin signalling, tissue fibrosis, and hyperandrogenism in PCOS-specific insulin resistance in lean and overweight women. PCOS-specific insulin signalling defects were isolated to mTOR, while gene expression implicated TGFß ligand regulating a fibrosis in the PCOS-obesity synergy in insulin resistance and altered responses to exercise. Interestingly, there was little evidence for hyperandrogenism as a mechanism for insulin resistance.
RESUMEN
Objective: Early menopause (EM), menopause aged <45 years, occurs spontaneously or secondary to medical treatments and is associated with multiple health impacts. A word cloud is an image where the word size reflects the frequency of use. We aimed to assess the perspectives of women with EM using a word cloud.Methods: Women diagnosed with EM, recruited from clinics/community, completed a survey including the open-ended question 'What words do you associate with EM?'. Demographics and medical history were collected. Data analysis included descriptive statistics, identification of word themes/stems/synonyms, word frequency, and chi-square test. A word cloud was constructed from words used by two or more women using 'Wordle' (www.wordle.net).Results: Responses were obtained from 190/263 participants. The mean age was 54 ± 11 years, with EM diagnosed at age 38 ± 5 years. The cause of EM was unknown (30% of women), bilateral oophorectomy (27%), cancer therapy (25%), or autoimmune/genetic/metabolic (17%). The commonest words reported were hot flushes (36.8% of women), mood swings (20.5%), and infertility (16.8%), which varied with age and cause of EM. Few women reported neutral/positive words.Conclusion: Most words that women associate with EM have negative connotations and refer to symptoms. A word cloud is a novel way to illustrate women's perspectives.

OBJECTIVE: To explore symptoms, understanding of menopausal therapies, medication use and health-related behavior in women with and without premature menopause. METHODS: Cross-sectional, questionnaire-based study involving a community-based sample of 77 women in Australia: 23 premenopausal, 25 with premature ovarian failure (POF) and 29 with medically induced premature menopause (MIPM). RESULTS: The median (interquartile range) age of each group was: premenopausal = 29 (13) years, POF = 36 (8.0) years and MIPM = 38 (4.0) years (p < 0.001). The reported frequency of menopausal symptoms differed across the groups for difficulty sleeping (premenopausal = 26%, POF = 44%, MIPM = 69%, p = 0.01), some depression symptoms (premenopausal = 4.4-22%, POF = 20-25%, MIPM = 38-59%, p < 0.05), hot flushes (premenopausal = 4.4%, POF = 28%, MIPM = 59%, p < 0.001), sweating at night (premenopausal = 4.4%, POF = 20%, MIPM = 52%, p < 0.001) and loss of interest in sex (premenopausal = 17%, POF = 52%, MIPM = 54%, p = 0.02). More women with premature menopause than premenopausal women reported taking prescription medication (premenopausal = 52%, POF = 92%, MIPM = 86%, p = 0.002), perceived that hormone therapy (HT) was associated with increased breast cancer risk (premenopausal = 43%, POF = 56%, MIPM = 79%, p = 0.03) and that HT prevented fractures (premenopausal = 13%, POF = 56%, MIPM = 39%, p = 0.01). Most women reported not knowing risks/benefits of bioidentical hormone therapy (premenopausal = 86%, POF = 56%, MIPM = 75%, p = 0.06). Regarding health-related behavior around prevention and screening, varying rates of bone densitometry (premenopausal = 4.4%, POF = 64%, MIPM = 59%, p < 0.001), blood glucose testing (premenopausal = 39%, POF = 67%, MIPM = 57%, p = 0.16) and cholesterol testing (premenopausal = 22%, POF = 71%, MIPM = 54%, p = 0.003) were reported. CONCLUSIONS: Differences in understanding of menopausal therapies and health-related behavior exist among women with premature menopause of differing etiology and premenopausal women. While perceived understanding of HT was greater than other therapies, targeted education is needed regarding specific risks/benefits of menopausal therapies and regarding preventive health screening after premature menopause.

OBJECTIVE: Investigation of clinicians' understanding of early menopause diagnosis/management in women with breast cancer. METHODS: A cross-sectional study of 176 randomly recruited Australian clinicians (35 gynecologists, 35 endocrinologists, 36 oncologists, 35 breast surgeons and 35 general practitioners (GPs)) involved in the care of women with breast cancer. This questionnaire study utilized an index case to assess understanding of early menopause diagnosis and management. Analysis involved descriptive statistics, χ² tests and Student's t-test. RESULTS: Significant differences between clinician groups regarding diagnostic criteria for early menopause were observed; gynecologists, endocrinologists and GPs selected amenorrhea > 12 months, whereas oncologists and breast surgeons selected elevated serum follicle stimulating hormone level (p < 0.05). Non-hormonal treatment was preferred by most clinician groups. Complementary/alternative medicines were more commonly prescribed by breast surgeons (57%), gynecologists (54%) and endocrinologists (49%) compared to oncologists (28%) or GPs (9%) (p = 0.0001). Exercise (63%) and nutrition (66%) were selected by most gynecologists for treatment of hot flushes, whereas endocrinologists (91%), oncologists (94%), breast surgeons (69%) and GPs (63%) prescribed venlafaxine. Hormone therapy was mainly prescribed by breast surgeons (43%) compared to other groups (p = 0.001). Most clinicians reported that the main problem with menopausal therapies was failure to resolve hot flushes. Exercise, lifestyle and stress management were recommended by all clinician groups for treatment of anxiety/depression. CONCLUSION: This exploratory study demonstrated a lack of consensus between clinician groups in their investigation, diagnosis and management of early menopause in women with breast cancer, with implications for both diagnosis and treatment.

BACKGROUND: The aim of this study was to assess the psychological features in women with different polycystic ovary syndrome (PCOS) phenotypes [National Institute of Health (NIH) and non-NIH diagnostic criteria] and women without PCOS. METHODS: An observational, cross-sectional study compared overweight (BMI ≥ 25 kg/m(2)) premenopausal women with PCOS (n = 29 NIH and n = 25 non-NIH) and controls (n = 27). Anxiety and depression were compared between women with NIH or non-NIH PCOS and women without PCOS. Health-related quality of life (HRQoL) domains related to emotions, body hair, weight, infertility and menstrual problems were compared between women with NIH and non-NIH PCOS. RESULTS: Overall, women with PCOS had worse anxiety (P = 0.007) and depression (P = 0.048) compared with women without PCOS. Both women with NIH PCOS and non-NIH PCOS presented more often with moderate anxiety (P = 0.005 and P = 0.01, respectively) compared with women without PCOS. Women with NIH PCOS had worse HRQoL related to infertility (P = 0.012), emotions (P = 0.02) and weight (P = 0.016). No significant differences were observed between the two PCOS phenotypes for HRQoL domains related to body hair or menstrual problems. Both NIH (ß = 0.30, P = 0.024) and non-NIH (ß = 0.32, P = 0.016) PCOS status predicted anxiety, whereas age (ß = 0.35, P = 0.008) and free androgen index (ß = 0.31, P = 0.027) predicted depression. CONCLUSIONS: PCOS is associated with anxiety and depression. Non-NIH phenotypes present with similar psychological profiles to NIH PCOS, indicating increased psychological dysfunction in PCOS, even in milder reproductive phenotypes. However, women with NIH PCOS appear to have worse HRQoL in some areas than women with non-NIH PCOS. Psychological function and HRQoL should be considered in all women with PCOS.

OBJECTIVE: To compare experience of premature menopause (PM), information sources, treatments, depression, anxiety, body image, sexual function and self-efficacy, between women with premature ovarian failure (POF), surgically induced menopause (SIPM), chemically induced menopause (CIPM), and controls. DESIGN: Cross-sectional observational pilot study using validated and devised questionnaires in 77 Australian women (POF, n = 25; SIPM, n = 17; CIPM, n = 12; controls, n = 23). RESULTS: The average age of all women was 34.8 years (standard deviation (SD) ± 5.7 years), and time since PM diagnosis was 3.8 years (SD ± 4.4 years, p = 0.19). The gynecologist (69%) and internet (67%) were the best expected sources of information. Women with PM feared osteoporosis more than controls (p < 0.0001). Women with SIPM (p = 0.006) and POF (p = 0.01) had higher rates of depression compared to controls. SIPM women were more anxious than women with POF (p = 0.04) and both SIPM (p = 0.002) and CIPM (p = 0.02) women were more anxious than controls. Women with POF had higher health evaluation (p = 0.03), fitness evaluation (p = 0.01) and fitness orientation (p = 0.01) than women with SIPM. Controls had higher health evaluation than women with SIPM (p = 0.001) and CIPM (p = 0.04), higher fitness evaluation than women with SIPM (p = 0.02) and CIPM (p = 0.04), and higher fitness orientation than SIPM women (p < 0.0001). Sexual dysfunction (p < 0.0001) and dyspareunia (p = 0.001) were higher in CIPM women than controls. Controls were more sexually responsive than POF women (p = 0.008). SIPM (p = 0.008) and POF (p = 0.04) women reported decreased confidence to manage disease. CONCLUSION: Depression, anxiety, body image, sexual dysfunction and self-confidence are compromised for women across different groups of premature menopause. Understanding these differences is important to the development of individual management plans based on the needs of women.

BACKGROUND: The impact of metabolic and reproductive features of polycystic ovary syndrome (PCOS) compromises psychological functioning. We investigated factors associated with negative psychological functioning to determine whether they were predictive of anxiety and depression in PCOS. METHODS: A cross-sectional study was performed by questionnaire in 177 women with PCOS (mean ± SD age 32.8 ± 7.8 years) and 109 healthy controls (mean age 41.9 ± 15.4 years). Main outcome measures were anxiety and depression, measured using the Hospital Anxiety Depression Scale (HADS) and Multidimensional Body-Self Relations Questionnaire (MBSRQ), respectively. RESULTS: Women with PCOS, compared with control women, had a higher mean anxiety HADS score (9.5 ± 3.9 versus 6.5 ± 3.6; P < 0.001), a higher mean depression score (5.7 ± 3.7 versus 3.3 ± 3.1; P < 0.001) and more negative body image in 7 out of 10 subscales of the MBSRQ. Multivariate regression analysis in PCOS showed that anxiety was predicted by self-worth (P < 0.0001), health evaluation (P = 0.005), time taken to diagnose PCOS (P = 0.003) and age (P = 0.02), while in control women, anxiety was predicted by self-worth (P = 0.009), health evaluation (P = 0.001) and rural living (P = 0.03). Depression in PCOS was predicted by self-worth (P = 0.0004), quality of life (QOL) (P = 0.004), fitness orientation (P = 0.002), appearance evaluation (P = 0.001) and time to diagnosis (P = 0.03) and in women without PCOS, by self-worth (P < 0.0001), QOL (P < 0.0001), illness orientation (P = 0.001) and appearance orientation (P = 0.02). CONCLUSIONS: Women with PCOS have increased anxiety, depression and negative body image compared with women without PCOS. In women with or without PCOS, body image and self-worth are predictors of both anxiety and depression, while QOL also predicts only depression. Time taken to diagnose PCOS is associated with poor psychological functioning.
