The use of repetitive transcranial magnetic stimulation (rTMS) as both therapeutic and experimental tools has grown enormously over the past decade. However, variability in response to rTMS is one challenge that remains to be solved. Estrogen can impact neural plasticity and may also affect plastic changes following rTMS. The present study investigated whether estrogen levels influence the neurophysiological effects of high-frequency (HF) rTMS in the left dorsolateral prefrontal cortex (DLPFC). It was hypothesised that individuals with higher endogenous estrogen would demonstrate greater rTMS-induced changes in cortical reactivity. 29 healthy adults (15M/14F) received HF-rTMS over left DLPFC. Females attended two sessions, one during a high-estrogen (HE) phase of the menstrual cycle, another during a low-estrogen (LE) phase. Males attended one session. Estrogen level was verified via blood assay. TMS-EEG was used to probe changes in cortical plasticity and comparisons were made using cluster-based permutation statistics and Bayesian analysis. In females , a significant increase in TMS-evoked P60 amplitude, and decrease in N45, N100 and P180 amplitudes was observed during HE. A less pervasive pattern of change was observed during LE. No significant changes in TEPs were seen in males. Between-condition comparisons revealed higher likelihood of the change in N100 and/or P180 being larger in females during HE compared to both females during LE and males. These preliminary findings indicate that a greater neuroplastic response to prefrontal HF-rTMS is seen in women when estrogen is at its highest compared to men, suggesting that endogenous estrogen levels contribute to variability in response to HF-rTMS. • The contribution of endogenous estrogen levels in response to HF-rTMS was examined using TMS-EEG in the DLPFC. • TMS-evoked potentials (TEPs) were compared between women during high and low estrogen phases of menstrual cycle and males. • High endogenous estrogen was associated with increased neuroplastic response to rTMS, which was reflected in all TEPs.

Objectives: It has been hypothesised that vasomotor symptoms (VMS), the hallmark of menopause, may affect women's workplace performance. The aim of this study was to investigate the association between VMS and self-reported work ability, taking into account socio-demographic characteristics. Study design/Main Outcome measures: A national cross-sectional survey of women, aged 40-65 years, was conducted between October 2013 and March 2014. Participants provided socio-demographic and lifestyle factors and completed the Menopause Specific Quality of Life Questionnaire (MENQOL) and the Work Ability Index (WAI).Results: Of 2020 women who comprised the study sample, 1274 were in paid employment and 1263 completed the WAI. The WAI score was good-excellent for 81.5% of women and poor-moderate for 18.5%. After adjustment for socio-demographic characteristics, having any VMS was associated with greater likelihood of poor-moderate work ability [odds ratio (OR)=2.45, 95% CI 1.69-3.54]. Poorer work ability was significantly and independently associated with being un-partnered, obese or overweight, smoking, being carer and having insecure housing finance, but not with age.Conclusions: Overall, most women functioned well at work. We observed an association suggesting a relationship not only between menopausal VMS and personal wellbeing, but also between VMS and self-assessed work ability. Although 4 in 5 women functioned well at work, recognition of the association with VMS may improve wellbeing and work performance of working women at midlife. [ABSTRACT FROM AUTHOR]

Objectives The extent to which menopause influences wellbeing is unclear. We investigated the association between moderate-severely bothersome vasomotor symptoms (VMS) and psychological general wellbeing in women, aged 40–65 years, taking into account socio-demographic and lifestyle factors. Study design/Main outcome measures This was a cross-sectional survey of 2020 Australian women, aged 40–65 years, recruited from the community between July 2013 and March 2014. Wellbeing was assessed by the Psychological and General Wellbeing questionnaire (PGWB) and VMS by the Menopause-specific Quality of Life Questionnaire. Results Moderate-severely bothersome VMS had a strong significant negative association with psychological general wellbeing [regression coefficient ( β ) = −8.17, 95% confidence interval (CI) −10.90 to −5.45]. Socio-demographic factors associated with lower wellbeing included being un-partnered ( β = −2.80, 95% CI −4.74 to −0.86), obese ( β = −5.46, 95% CI −7.24 to −3.68) and a smoker ( β = −3.47, 95% CI −6.10 to −0.84). Older age ( β = 0.29, 95% CI 0.06–0.42) and participation in paid and/or volunteer work ( β = 2.72, 95% CI 0.61–4.82) were positively associated with wellbeing. For those with insecure housing, being a carer was associated with better wellbeing. Conclusions Moderate-severely bothersome VMS are significantly and independently negatively associated with psychological general wellbeing in women at midlife. This is an important consideration when assessing psychological wellbeing in women during this life phase. [ABSTRACT FROM AUTHOR]
