INTRODUCTION: Considering that estradiol (E2) and n-3 polyunsaturated fatty acids (PUFAs) have roles in neurogenesis and in neurotransmission, we examined whether the association of PUFAs with incident depressive symptoms in postmenopausal women is modified by hormone therapy (HT) use or estrogen status. METHODS: Women (N=1616) free of depressive symptoms at baseline (2000-2002) in the Multi-Ethnic Study of Atherosclerosis were classified by HT usage and quartiles of dietary eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and the sum EPA+DHA...

CONTEXT: Breast cancer is the most common cancer in women worldwide. Estrogen receptor (ER) positive breast cancer constitutes the majority of these cancers. Hormone therapy has significantly improved clinical outcomes for early- and late-stage hormone receptor positive breast cancer. Although most patients with early stage breast cancer are treated with curative intent, approximately 20% - 30% of patients eventually experience a recurrence. During the last two decades, there have been tremendous efforts to understand the biological mechanisms of hormone therapy resistance, with the ultimate goal of implementing new therapeutic strategies to improve the current treatments for ER positive breast cancer...

BACKGROUND: Many factors, such as heredity, ethnicity, nutrition and other lifestyle factors, have been related to bone mineral density in postmenopausal women. Additionally, bone mass has been significantly associated with decreased estrogen levels. However, fewstudies have been conducted on premenopausal women. The present study was designed to estimate the relationship between low bone mineral density and levels of serum estradiol and lifestyle factors in premenopausal Mexican women...

Menopause is a natural event in women´s lives leading to the cessation of menstruation and the reproductive function due to loss of the ovarian follicular function. Menopause-derived estrogen deprivation and related endocrine factors are linked to some symptoms of middle-aged women, such as hot flashes, aches, joint pain, stiffness, depressed mood, bone degeneration, nutritional dysfunction, or difficulty to maintain body mass. Clinical approaches to these problems often involve hormone replacement therapy (HRT) and other modalities of therapeutic intervention...

Recent data show shifts in genetic and environmental influences on emotional eating across the menstrual cycle, with significant shared environmental influences during pre-ovulation, and primarily genetic effects during post-ovulation. Factors driving differential effects are unknown, although increased estradiol during pre-ovulation and increased progesterone during post-ovulation are thought to play a role. We indirectly investigated this possibility by examining whether overall levels of estradiol and progesterone differentially impact genetic and environmental risk for emotional eating in adult female twins (N = 571) drawn from the MSU Twin Registry...

It is estimated that up to 80% of women experience symptoms related to declining estrogen levels that occur with menopause. The most common bothersome symptoms reported by women during and after this transition are vasomotor symptoms, which can include hot flashes, flushing, night sweats, and sleep disturbances. These symptoms are the most common reason women seek care during menopause. Until recently, the mainstay of treatment and symptom relief has been estrogen supplementation. In 2013, the U.S. Food and Drug Administration approved paroxetine, a low-dose selective serotonin reuptake inhibitor, as the first nonhormonal treatment for moderate to severe vasomotor symptoms of menopause...

BACKGROUND: Single nucleotide polymorphisms (SNPs) involved in the estrogen pathway and SNPs in the estrogen receptor alpha gene (ESR1 6q25) have been linked to breast cancer development, and mammographic density is an established breast cancer risk factor. Whether there is an association between daily estradiol levels, SNPs in ESR1 and premenopausal mammographic density phenotypes is unknown. METHODS: We assessed estradiol in daily saliva samples throughout an entire menstrual cycle in 202 healthy premenopausal women in the Norwegian Energy Balance and Breast Cancer Aspects I study...

Endometrial cancer is the most common gynecological cancer and the sixth most common cancer among women in Taiwan. Risk factors for endometrial cancer include obesity, long-term estrogen replacement therapy, diabetes mellitus, hypertension, nulliparty, early age at menarche, late age at menopause, and tamoxifen therapy. Most women with endometrial cancer exhibit abnormal uterine bleeding. Endometrial cancer is often diagnosed at stage I. Surgery alone is the primary treatment for stage I endometrial cancer...

In premenopausal women, ovarian steroids are felt to play a role in the prevention of cardiovascular disease. We aimed to assess whether menstrual cycle variations in estrogen can modify the response to ischemia-reperfusion (IR) injury in humans. In an investigator-blinded crossover study, 10 healthy premenopausal women with regular menstrual cycles were studied. They had flow-mediated dilatation (FMD) measured by ultrasound in the radial artery before and after IR (15 min of brachial artery ischemia, 15 min of reperfusion) during both the early and late follicular phases of the menstrual cycle...

BACKGROUND: Dietary energy density (ED) is a measure of diet quality that estimates the amount of energy per unit of food (kilocalories per gram) consumed. Low-ED diets are generally high in fiber and fruits and vegetables and low in fat. Dietary ED has been positively associated with body mass index (BMI) and other risk factors for postmenopausal breast cancer. OBJECTIVE: We evaluated the associations of total dietary ED and energy-dense (high-ED) foods with postmenopausal breast cancer incidence...

Macrophages play an important role in the origin and development of endometriosis. Estrogen promoted the growth of decidual stromal cells (DSCs) via down-regulating the level of interleukin (IL)-24. The aim of this study was to clarify the role and mechanism of IL-24 and its receptors in biological functions regulation of endometrial stromal cells (ESCs) from endometriosis. The level of IL-24 and its receptors in endometrium was measured by immunohistochemistry. In vitro analysis was used to measure the level of IL-24 and receptors and the biological behaviors of ESCs...

INTRODUCTION: The benefit of adjuvant trastuzumab with chemotherapy is well established for women with higher risk human epidermal growth factor receptor 2-positive (HER2(+)) breast cancer. However, its role in older patients with smaller, node-negative tumors is less clear. We conducted a retrospective, sequential cohort study of this population to describe the impact of trastuzumab on breast cancer outcomes and cardiac safety. PATIENTS AND METHODS: Women ≥ 55 years with ≤ 2 cm, node-negative, HER2(+) breast cancer were identified and electronic medical records reviewed...

BACKGROUND: Sexual dysfunction is common among US women of reproductive age, many of whom use contraception. Various contraceptive methods have been associated with changes in sexual function. METHODS: In this narrative review, we selected key articles based on our collective clinical experience. We summarized findings and best practice recommendations for addressing a woman's contraception and its potential relationship to sexual function. RESULTS: Although some hormonal contraception is associated with sexual dysfunction, studies show mixed results based on route of administration and progestin component...

Menopausal women often suffer from hot flashes and sleep disturbances that significantly impact their quality of life. Both human and animal studies suggest that loss of estrogens during menopause contribute to these symptoms. In the female rat, both core body temperature (CBT) and sleep are sensitive to 17β-estradiol (E2) levels, but important differences between the rat and the human patterns limit the interpretation of the results. The sleep and thermoregulation of the common marmoset (Callithrix jacchus) more closely resemble human patterns...

The uptake of selective estrogen receptor modulators (SERMs) and aromatase inhibitors (AIs) for the primary prevention of breast cancer is low, despite their proven efficacy in several randomized clinical trials. This review summarizes the latest data on physicians' and women's barriers to breast cancer preventive therapy. Physicians' challenges include: identifying suitable candidates for preventive therapy, inadequate training and confidence in risk assessment and counselling, insufficient knowledge of risk-reducing medications, and lack of time...

Alcohol intake has been related to an increased risk of breast cancer (BC) while dietary fiber intake has been inversely associated to BC risk. A beneficial effect of fibers on ethanol carcinogenesis through their impact on estrogen levels is still controversial. We investigated the role of dietary fiber as a modifying factor of the association of alcohol and breast cancer using data from the European Prospective Investigation into Cancer and Nutrition (EPIC). This study included 334,850 women aged 35-70 years at baseline enrolled in the ten countries of the EPIC study and followed up for 11...

OBJECTIVE: The effects of estetrol (E4), a natural fetal estrogen, combined with drospirenone (DRSP) were evaluated on plasma levels of sex hormone-binding globulin (SHBG), angiotensinogen and 12 hemostasis markers. STUDY DESIGN: Combinations of 3 mg DRSP with 5 or 10 mg E4 were compared with YAZ® (20 mcg ethinyl estradiol and 3 mg DRSP; EE/DRSP) in parallel groups of 15-18 healthy young women. Main outcome was the relative change from pretreatment to the end (day 24±1) of the third treatment cycle...

BACKGROUND: The number of involved axillary lymph nodes (LNs) found pathologically is regarded as a significant prognostic factor in early-stage breast cancer (EBC). Recently, there is speculation that LN ratio (LNR) may be a better surrogate at predicting cancer-specific outcome than number of involved LNs. This study investigated prognostic value of LNR, using predetermined cutoff values. METHODS: Data included all women diagnosed with node-positive EBC between January 1, 2001, and December 31, 2010 (N = 553)...

STUDY QUESTION: Does adrenocorticotropic hormone (ACTH) induce gonadotropin release in premenopausal women? SUMMARY ANSWER: Administration of ACTH stimulates gonadotropin release, most likely by stimulation of the production of cortisol, in premenopausal women. WHAT IS KNOWN ALREADY: In animal models, acute activation of the hypothalamic-pituitary-adrenal (HPA) axis has been shown to induce gonadotropin release in the presence of sufficiently high estrogen levels...
