Dietary isoflavones, urinary isoflavonoids, and risk of ischemic stroke in women Nutritional epidemiology and public health
Conclusions: A habitually high intake of soy isoflavones may be associated with a modest but significant increase in risk of ischemic stroke in women. However, no association was shown for the urinary excretion of isoflavonoids.

Postmenopausal Hormone Therapy and the Risks of Coronary Heart Disease, Breast Cancer, and Stroke
Semin Reprod Med 2014; 32: 419-425DOI: 10.1055/s-0034-1384624The principal findings are briefly reviewed from the Women's Health Initiative trials of the most commonly used postmenopausal hormone regimens in the United States—conjugated equine estrogens and these same estrogens plus medroxyprogesterone acetate. A more detailed review is presented for three major clinical outcomes: coronary heart disease (CHD), the primary trial outcome for which a major benefit was hypothesized; invasive breast cancer, the primary safety outcome for which some adverse effect was expected; and stroke which surfaced as an important adverse...

Stroke Findings in the Women's Health Initiative
Semin Reprod Med 2014; 32: 438-446DOI: 10.1055/s-0034-1384627The Women's Health Initiative (WHI) clinical trials of estrogen with or without progestin versus placebo in 27,341 postmenopausal women are the largest randomized, placebo-controlled, double-blind clinical trials to look at the effect of hormone therapy on the outcomes of stroke, dementia, and cognition. Data from a parallel prospective observational study of 93,676 women examine biomarkers and risk factors associated with stroke. We summarize the results of 29 published articles in the WHI with stroke or cognition as outcomes of interest. Estrogen alone or in co...

Prevention of Cardiovascular Disease in Women
Semin Reprod Med 2014; 32: 447-453DOI: 10.1055/s-0034-1384628Cardiovascular disease is the leading cause of death among women. In fact, the cardiovascular disease mortality rate among women exceeds the rate in men. Unfortunately, many minority women are still unaware of the importance of this disease. All women, including those with no history of cardiovascular disease, should have an accurate estimate of the probability of a cardiovascular disease event (death, myocardial infarction, or stroke) usually within the next decade. Such an estimate will help determine if women are candidates for preventive measures and specific...

17-beta estradiol inhibits oxidative stress-induced accumulation of AIF into nucleolus and PARP1-dependent cell death via estrogen receptor alpha.
Abstract Oxidative stress-induced DNA damage results in over-activation of poly(ADP-ribose) polymerase 1 (PARP1), leading to parthanatos, a newly discovered cell elimination pathway. Inhibition of PARP1-dependent cell death has shown to improve the outcome of diseases, including stroke, heart ischemia, and neurodegenerative diseases. In the present study we aimed to detect whether estrogen plays a protective role in inhibiting parthanatos. We utilized human mammary adenocarcinoma cells (MCF7) that abundantly express the estrogen receptor alpha and beta (ERα and ERβ). Parthanatos was induced by challenging the ce...

Menopausal hormone therapy has risks and benefits during the intervention and poststopping phase
This report summarises the previous WHI reports alongside 13 years of follow-up in 81.1% of surviving participants. Some selection bias may have occurred in the postintervention phase due to occurrences in the intervention phase. Methods Women were recruited from 1993 to 1998...

Cardiovascular benefits of HRT may differ by patient age
Commentary on: Main C, Knight B, Moxham T, et al.. Hormone therapy for preventing cardiovascular disease in post-menopausal women. Cochrane Database Syst Rev 2013;(4):CD002229. Context In early postmenopausal women oestrogen and/or hormone replacement therapy (ERT/HRT) are used to alleviate symptoms and reduce the probability of diseases related to ovarian hormones deprivation. However, in late postmenopausal women the initiation of HRT has a negative risk/benefit balance mainly because of the increased risk of cardiovascular diseases (CVD). Methods Main et al performed a meta-analysis of randomised controlled trials (RCTs...

Association of Ischemic Stroke, Hormone Therapy, and Right to Left Shunt in Postmenopausal Women
Conclusions Approximately 20% of older women have a right to left shunt. Hormone therapy in these women may increase the risk of ischemic stroke by promoting paradoxical embolism. © 2014 Wiley Periodicals, Inc.

Impact of methodology on estrogens' effects on cerebral ischemia in rats: an updated meta-analysis
Conclusions: We conclude that the discordant results regarding estrogens' effects in rat models of ischemic stroke are a consequence of differences in estrogen administration modes. These results are not only of importance for the ongoing debate regarding menopausal hormone therapy, but also have an important bearing on experimental stroke methodology and the apparent translational roadblock for suggested stroke interventions.

While hormone therapy unlikely harmful in younger postmenopausal women at low CV risk, protective effects cannot be claimed
Commentary on: Schierbeck LL, Rejnmark L, Tofteng CL, et al.. Effect of hormone replacement therapy on cardiovascular events in recently postmenopausal women: randomised trial. BMJ 2012;345:e6409. Context The last 10 years have clarified the issues regarding postmenopausal hormone therapy (HT) and cardiovascular disease (CVD). Prior to the large, randomised women's health initiative (WHI),1 observational studies had suggested a protective cardiovascular (CV) effect. The WHI showed no benefit, and increased thromboembolic and CV events in women taking HT. The WHI findings have been challenged because of the older age of the...

Hormone therapy not recommended for chronic disease prevention in menopausal women
Commentary on: Nelson HD, Walker M, Zakher B, et al.. Menopausal hormone therapy for the primary prevention of chronic conditions: a systematic review to update the US Preventive Services Task Force recommendations. Ann Intern Med 2012;157:104–13. Context In 2005, the US Preventive Services Task Force (USPSTF) updated its 2002 hormone replacement therapy recommendations, advising against the routine use of oestrogen and progestin (E+P) and unopposed oestrogen (E) to prevent chronic conditions in menopausal women. Menopausal hormone therapy (MHT) had been commonly prescribed to prevent conditions such as cardiovascula...
