Soy intake and vasomotor menopausal symptoms among midlife women: a pooled analysis of five studies from the InterLACE consortium

Management of vasomotor symptoms in cancer patients

Many cancer treatments can lead to reduced levels of sex hormones, which in turn may cause vasomotor symptoms (VMS) such as hot flashes. These symptoms are associated with impaired quality of life, as well as suboptimal tolerability of and adherence to cancer treatment. Hormone therapy, performed by increasing estradiol or testosterone levels, is the gold standard for treatment of VMS. However, this approach is generally contraindicated in patients with hormone-sensitive cancers. Nonhormone agents with low to moderate efficacy in controlling VMS are available, but their use may be limited by side effects and tolerability. In this narrative review, the approach to VMS in cancer patients will be discussed. The evidence for various treatment options, including novel agents such as fezolinetant that target the hypothalamic thermoregulatory pathway, will be evaluated. Finally, special considerations in different patient populations based on cancer types (eg, breast, prostate) and age groups (eg, older adults) will be explored.

Associations of menopausal symptoms with job-related stress and social support in Japanese school teachers

OBJECTIVES

Being a school teacher is highly stressful. This study aimed to clarify the prevalence of menopausal symptoms and explore the association between these symptoms and job-related stress among Japanese school teachers.

STUDY DESIGN

A cross-sectional study was conducted among randomly selected elementary and junior high school teachers in Japan. Data from 284 teachers aged 45-60 years were analyzed.

MAIN OUTCOME MEASURES

Menopausal symptoms were measured using the Greene Climacteric Scale, and the Brief Job Stress Questionnaire was used to assess job stressors, social support, and job/family satisfaction. Associations between scores on the Greene Climacteric Scale and on the Brief Job Stress Questionnaire, and demographic information were analyzed.

RESULTS

The most common menopausal symptom was "feeling tired or lacking in energy" (reported by 94.4 % of respondents). The total intensity of menopausal, psychological, and somatic symptoms was significantly correlated with the total level of job stress. Moderate correlations were found between depressive symptoms and job stress regarding suitable jobs, job control, and rewarding jobs, while weak correlations were evident between depressive symptoms and job stress regarding quantitative job overload, interpersonal conflict, and poor physical environment. Higher levels of perceived support from supervisors or co-workers and job satisfaction were associated with less severe psychological and somatic symptoms.

CONCLUSIONS

Most middle-aged school teachers felt tired or lacking in energy. Higher job-related stress and lower levels of support from supervisors or co-workers were correlated with more severe menopausal symptoms. A supportive work environment and stress management are essential for such teachers.

Estradiol and Estrogen-like Alternative Therapies in Use: The Importance of the Selective and Non-Classical Actions

Estrogen is one of the most important female sex hormones, and is indispensable for reproduction. However, its role is much wider. Among others, due to its neuroprotective effects, estrogen protects the brain against dementia and complications of traumatic injury. Previously, it was used mainly as a therapeutic option for influencing the menstrual cycle and treating menopausal symptoms. Unfortunately, hormone replacement therapy might be associated with detrimental side effects, such as increased risk of stroke and breast cancer, raising concerns about its safety. Thus, tissue-selective and non-classical estrogen analogues have become the focus of interest. Here, we review the current knowledge about estrogen effects in a broader sense, and the possibility of using selective estrogen-receptor modulators (SERMs), selective estrogen-receptor downregulators (SERDs), phytoestrogens, and activators of non-genomic estrogen-like signaling (ANGELS) molecules as treatment.

Vasomotor symptoms, sleep problems, and depressive symptoms in community-dwelling Japanese women

Aim

To assess prevalence and characteristics of vasomotor symptoms in community‐dwelling Japanese women.

Methods

These were cross‐sectional analyses using data from the National Institute for Longevity Sciences‐Longitudinal Study of Aging. The main outcome measures were prevalence and severity of hot flashes and sweating. Associations between hot flashes/sweating (slight, moderate, or severe vs none) and sleep problems were explored using logistic regression, with and without adjustment for age, daily physical activity, and number of urinations/night. Associations between hot flashes/sweating and sleep problems, depressive symptoms, and dietary variables were explored in logistic regression models or general linear models.

Results

A total of 1152 women between 40 and 91 years of age were enrolled. Hot flashes were reported by 24.5% of participants; with prevalence and severity highest in those 50–54 years or 2–5 years postmenopause. Sleep problems were reported 15 percentage points more frequently by women who reported hot flashes than by those without hot flashes. Adjusted odds ratios [95% CI] for difficulty in falling asleep and difficulty in sleeping through were 2.09 [1.565–2.796] and 2.07 [1.549–2.763]), respectively. Also, hot flashes were associated with higher risk of depressive symptoms (adjusted odds ratio [95% CI]: 2.99 [2.07–4.32]) and lower life satisfaction, self‐esteem, and self‐rated health status. A similar pattern was observed in women with and without sweating. No associations were found between hot flashes and dietary factors.

Conclusions

Clear associations were found between hot flashes and sleeping problems, even after adjusting for potential confounding factors. Women who reported hot flashes also reported worse mental and physical health than those who did not report hot flashes.

Soy intake and chronic disease risk: findings from prospective cohort studies in Japan

There has been much interest in the potential role of soy in reducing the risk of chronic diseases. Soy foods are uniquely rich in isoflavones, a fact that has triggered much research including intervention studies. However, there have been few long-term prospective observational studies that include disease itself as an outcome. High intake of soy foods is intrinsic to the Japanese diet, which can be advantageous for conducting such studies in Japan. The present report reviews the findings from Japanese prospective cohort studies on soy intake and the risk of cardiovascular diseases, cancer, type 2 diabetes, osteoporosis, menopausal symptoms, and dementia. The results suggest a beneficial role of soy in several chronic diseases, but they are not without controversy. Discrepancies have been observed in the findings of studies of Japanese or other Asians as compared to those of non Asians. This review discusses the issues to be explored in future studies.
