BACKGROUND Postmenopausal women are prone to develop functional disabilities as a result of reduction in muscle strength and muscle mass caused by diminished levels of female sex hormones. While hormone replacement therapy may counteract these changes, conventional hormone replacement therapy is associated with potential harmful effects, such as an increased risk of breast cancer, and its presc...
Osteoporosis is a significant source of morbidity and mortality in industrialized nations enjoying the benefits of an extended life span. Besides drug treatment (e.g. corticoids, antiepileptics, anticoagulants) and specific, but quite rare, endocrine, hematologic or rheumatologic disorders, estrogen deficiency from secondary amenorrhea or after menopause is the most common cause of osteoporosis...
Several large, prospective trials have evaluated tamoxifen compared with placebo for breast cancer risk reduction in women at increased risk for breast cancer. Analysis of the large, prospective breast cancer risk-reduction trials that used tamoxifen estimated that tamoxifen decreased breast cancer incidence by 38% on average and estrogen receptor-positive tumors by 48%. Tamoxifen is known to h...
Although sex steroids are known to modulate brain dopamine, it is still unclear how testosterone modifies locomotor behaviour controlled, at least in part, by striatal dopamine in adolescent males. Our previous work suggests that increasing testosterone during adolescence may bias midbrain neurons to synthesise more dopamine. We hypothesised that baseline and amphetamine-induced locomotion woul...
BACKGROUND Mammographic density is a risk factor for breast cancer. Mammographic density and breast magnetic resonance imaging (MRI) volume (MRIV) assess the amount of fibroglandular tissue in the breast. Mammographic density and MRIV can be modulated with hormonal interventions, suggesting that these imaging modalities may be useful as surrogate endpoint biomarkers for breast cancer chemopreve...
It has been previously reported that the neuroprotective hormone oestradiol reduces microglia inflammatory activity. The objective of this study was to test whether two selective oestrogen receptor modulators, tamoxifen and raloxifene, modulate in vivo the activation of microglia induced by the peripheral administration of lipopolysaccharide (LPS). Activation of microglia was assessed in the wh...
INTRODUCTION Endometrial hyperplasia is a condition that occurs as a result of hormonal imbalance between estrogen and progesterone. Morphological disturbance of endometrial cells occurs consequently leading towards endometrial cancer. In therapy of endometrial hyperplasia SERMs are used to supress effects of locally high estrogen level in uterus. There is strong evidence suggesting that estrog...
Lippman et al. (1) assess the effect of raloxifene on the incidence of breast cancer in women with defined risk factors. However, raloxifene is used in clinical practice for the treatment and prevention of osteoporosis in postmenopausal women. To the casual observer, the application of a medicine to treat and prevent osteoporosis would seem to be counterintuitive as estrogen is known to build b...
Elevated insulin-like growth factor I (IGF-I) is associated with an increased risk for developing breast cancer in premenopausal women, whereas lower leptin levels have been documented in premenopausal breast cancer cases. We determined the effect of raloxifene on IGF-I, insulin-like growth factor binding protein 3 (IGFBP-3), and leptin in premenopausal women at high risk for developing invasiv...
OBJECTIVE To monitor the effects of raloxifene therapy on the uterus of postmenopausal women by transvaginal ultrasonography and color flow Doppler. METHODS Twenty-five healthy postmenopausal women were enrolled in this prospective longitudinal study performed at Department of Gynecology and Obstetrics, Faculty of Medicine of Ribeirão Preto. The patients were treated with raloxifene hydrochlo...
