Perimenopause: an update

Estrogen: a master regulator of bioenergetic systems in the brain and body

Estrogen is a fundamental regulator of the metabolic system of the female brain and body. Within the brain, estrogen regulates glucose transport, aerobic glycolysis, and mitochondrial function to generate ATP. In the body, estrogen protects against adiposity, insulin resistance, and type II diabetes, and regulates energy intake and expenditure. During menopause, decline in circulating estrogen is coincident with decline in brain bioenergetics and shift towards a metabolically compromised phenotype. Compensatory bioenergetic adaptations, or lack thereof, to estrogen loss could determine risk of late-onset Alzheimer's disease. Estrogen coordinates brain and body metabolism, such that peripheral metabolic state can indicate bioenergetic status of the brain. By generating biomarker profiles that encompass peripheral metabolic changes occurring with menopause, individual risk profiles for decreased brain bioenergetics and cognitive decline can be created. Biomarker profiles could identify women at risk while also serving as indicators of efficacy of hormone therapy or other preventative interventions.

Relieving my discomforts safely: the experiences of discontinuing HRT among menopausal women

AIM AND OBJECTIVES

To generate a descriptive theoretical framework about the experiences of women who discontinued hormone replacement therapy.

BACKGROUND

Some menopausal women would depend on hormone replacement therapy for relieving their menopausal symptoms. However, most of them feared of hormone replacement therapy's side effects and tried to discontinue hormone replacement therapy immediately. How did these women self-manage their discomforts without using dependent medicine--hormone replacement therapy? There are few studies conducted on this issue.

DESIGN

A grounded theory research was applied.

METHODS

Nineteen Taiwanese women discontinuing hormone replacement therapy for three months, aged 45 to 67 years, participated in face-to-face audio-taped interviews. Data collection, and coding of interviews, and data analysis occurred simultaneously. All conversations were audio-recorded and then transcribed as verbatim text. The constant comparative method was used to analyse the interview data.

RESULTS

'Relieving my discomforts safely' was the core theme for describing and guiding the process of discontinuing hormone replacement therapy. 'Immediately discontinuing hormone replacement therapy--it would hurt my body' was identified as the antecedent condition. Analyses showed five dimensions to the women's relieving my discomforts safely: (1) symptoms bothered me again, (2) negative emotions, (3) learning to let it go, (4) trying to use nonhormone replacement therapy or products and (5) choosing safely therapies as first priority. Finally, some women would choose their suitable nonhormone replacement therapy way, and some women would reuse hormone replacement therapy cautiously.

CONCLUSIONS

'Relieving my discomforts safely' was the first-priority consideration for the menopausal women discontinuing hormone replacement therapy. It is the challenge to establish the health programme or management for helping these women felt safety and security to relieve their menopausal symptoms by using hormone replacement therapy or nonhormone replacement therapy.

RELEVANCE TO CLINICAL PRACTICE

Healthcare providers need to empower women the rights of decision-making of using hormone replacement therapy and assist them in monitoring their health status to reduce their fear and uncertainty.

Hot flashes and sleep in women

Sleep disturbances during menopause are often attributed to nocturnal hot flashes and 'sweats' associated with changing hormone patterns. This paper is a comprehensive critical review of the research on the relationship between sleep disturbance and hot flashes in women. Numerous studies have found a relationship between self-reported hot flashes and sleep complaints. However, hot flash studies using objective sleep assessment techniques such as polysomnography, actigraphy, or quantitative analysis of the sleep EEG are surprisingly scarce and have yielded somewhat mixed results. Much of this limited evidence suggests that hot flashes are associated with objectively identified sleep disruption in at least some women. At least some of the negative data may be due to methodological issues such as reliance upon problematic self-reports of nocturnal hot flashes and a lack of concurrent measures of hot flashes and sleep. The recent development of a reliable and non-intrusive method for objectively identifying hot flashes during the night should help address the need for substantial additional research in this area. Several areas of clinical relevance are described, including the effects of discontinuing combined hormone therapy (estrogen plus progesterone) or estrogen-only therapy, the possibility of hot flashes continuing for many years after menopause, and the link between hot flashes and depression.
