Risk of Stroke With Various Types of Menopausal Hormone Therapies Brief Report
Conclusions—In a national setting, we found an increased risk of stroke, based on ischemic stroke, with oral hormone therapies that was comparable to findings from randomized studies. We found no risk of stroke with transdermal application and a reduced risk with vaginal estrogen.

Low Dehydroepiandrosterone Sulfate is Associated With Increased Risk of Ischemic Stroke Among Women Clinical Sciences
Conclusions— Lower DHEAS levels were associated with a greater risk of ischemic stroke, even after adjustment for potential confounders. These novel observations warrant confirmation in other populations.

Sex Differences in Trends of Incidence and Mortality of First-Ever Stroke in Rural Tianjin, China, From 1992 to 2012 Clinical Sciences
Conclusions— There was a significant increase in the incidence of first-ever stroke in women annually and a declining trend in the male/female rate ratio in rural China during the past 21 years. These results suggest that stroke will become one of the major diseases affecting women in future decades in China.

X, but not Y, Chromosomal Complement Contributes to Stroke Sensitivity in Aged Animals
AbstractPost-menopausal women become vulnerable to stroke and have poorer outcomes and higher mortality than age-matched men, and previous studies suggested that sex chromosomes play a vital role in mediating stroke sensitivity in the aged. It is unknown if this is due to effects of the X or Y chromosome. The present study used the XY* mouse model (with four genotypes: XX and XO gonadal females and XY and XXY gonadal males) to compare the effect of the X vs. Y chromosome compliment in stroke. Aged (18 –20 months) and gonadectomized young (8–12 weeks) mice were subjected to a 60-min middle cerebral artery occlusion. I...

HRT review finds increased risk of blood clots and stroke
Conclusion This updated Cochrane review has found that oral HRT increases risk of stroke and blood clots, and does not appear to reduce overall risk of cardiovascular disease or death during follow-up. More exploratory analyses suggested that HRT might reduce risk of death from heart disease or non-fatal heart attack if it was started within 10 years of menopause, but this finding needs further confirmation. The review was carried out using robust methods and the trials were of good quality. Its findings are in line with the previous version of the review, and also with other reviews. There are some points to note: Thi...

Short-term exposure to air pollution and incidence of stroke in the Women's Health Initiative.
CONCLUSIONS: In this large cohort of post-menopausal US women, daily NO2 and NOx were associated with higher risk of hemorrhagic stroke, but ambient levels of four other air pollutants were not associated with higher risk of total stroke, ischemic stroke, or ischemic stroke subtypes.

Elevated ischemic stroke risk among women living with HIV infection
Conclusion: The increased risk of ischemic stroke among WLWH compared with HIV-uninfected women persisted after adjusting for both traditional and sex-specific stroke risk factors. Further investigation into the mechanisms of elevated stroke risk among WLWH, including immunologic factors, will be key for developing targeted preventive strategies for this at-risk population.

Increased P450 aromatase levels in post-menopausal women after acute ischemic stroke
ConclusionsEstradiol levels correlated with functional outcomes (change in mRS) in both men and women, at least in the acute phase (24  h) of stroke. However, no significant difference in estradiol levels is seen 24 h post-stroke in men or women. Testosterone levels decrease at 24 h after stroke in men. As seen in animal models, aromatase levels increase after acute ischemic stroke, but this was only true for women. These ind icate an active aromatization process in post-menopausal women after acute ischemic stroke.

Stroke as an Antecedent Risk Factor for Depression among Post-Menopausal Women
ConclusionsA significant association between previous stroke and current depression was found in this population, independent of vascular disease risk measures among post-menopausal women. These findings highlight the possible importance of screening for and treating depression among stroke survivors. Longitudinal studies need to be conducted assessing the mental health impact of stroke.Key messagesOccurrence of stroke may lead to an increased likelihood of depression, especially among post-menopausal women.Due to the global COVID-19 pandemic, surveillance efforts should include mental health complication including those related to stroke.

Postmenopausal hormone therapy and risk of stroke: A pooled analysis of data from population-based cohort studies
by Germ án D. Carrasquilla, Paolo Frumento, Anita Berglund, Christer Borgfeldt, Matteo Bottai, Chiara Chiavenna, Mats Eliasson, Gunnar Engström, Göran Hallmans, Jan-Håkan Jansson, Patrik K. Magnusson, Peter M. Nilsson, Nancy L. Pedersen, Alicja Wolk, Karin Leander BackgroundRecent research indicates a favourable influence of postmenopausal hormone therapy (HT) if initiated early, but not late, on subclinical atherosclerosis. However, the clinical relevance of timing of HT initiation for hard end points such as stroke remains to be determined. Further, no previous research has considered the timing of initiation of HT i...

Post-stroke neovascularization and functional outcomes differ in diabetes depending on severity of injury and sex: Potential link to hemorrhagic transformation.
Abstract Diabetes is associated with increased risk and worsened outcome of stroke. Previous studies showed that male diabetic animals had greater hemorrhagic transformation (HT), profound loss of cerebral vasculature, and poor behavioral outcomes after ischemic stroke induced by suture or embolic middle cerebral artery occlusion (MCAO). Females are protected from stroke until reaching the menopause age, but young females with diabetes have a higher risk of stroke and women account for the majority of stroke mortality. The current study postulated that diabetes is associated with greater vascular injury and exacer...

Effect of Sex and Age Interactions on Functional Outcome after Stroke.
Abstract Stroke is one of the leading causes of death and disability worldwide. Experimental and clinical studies showed that sex and age play an important role in deciding the outcome after stroke. At younger ages, males were shown to have a higher risk for stroke than females. However, this trend reverses in older ages particularly when females reach menopause. Many preclinical studies indicate that steroid hormones modulate the age-dependent differential stroke outcome. In addition, patterns of cell death pathways activated following cerebral ischemia are distinct between males and females, but independent of s...

Plasma uric acid concentrations and risk of ischaemic stroke in women
ConclusionsPlasma uric acid levels were not independently associated with increased risk of ischaemic stroke in this cohort of women. Whilst plasma uric acid was associated with stroke risk factors, it was not independently associated with stroke risk.
