This article highlights the latest findings regarding estrogen replacement therapy in the treatment and prevention of Alzheimer's disease (AD) and mild cognitive impairment in women. Despite considerable evidence from observational studies, recent randomized clinical trials of conjugated equine estrogens, alone and in combination with progestin, have shown no benefit for either the treatment of established AD or for the short-term prevention of AD, mild cognitive impairment, or cognitive decline. Based on the evidence, there is no role at present for estrogen replacement therapy in the treatment or prevention of AD or cognitive decline, despite intriguing results from the laboratory and from observational studies. However, numerous questions remain about the biologic effects of estrogens on brain structure and function. Additional basic and clinical investigations are necessary to examine different forms and dosages of estrogens, other populations, and the relevance of timing and duration of exposure.

2-Ethylhexyl diphenyl phosphate (EHDPP) is a replacement flame-retardant commonly found in several environmental matrices and human biospecimens. Although some adverse effects of EHDPP have been identified, the endocrine-disrupting effects of EHDPP and its key metabolites on the human estrogen receptor (ER) are largely unknown. Herein, we report for the first time that EHDPP, at concentrations found in the environment and humans, significantly promoted estrogenic activity and synergized with 17β-estradiol-induced ER transactivation.

Objectives: Temporomandibular joint osteoarthritis (TMJ-OA) with condylar resorption is a multifactorial condition involving hormonal imbalance and articular disk dysfunction, often leading to severe TMJ degeneration. This study investigated the combined effects of estrogen deficiency and anterior articular disk derangement (ADD) on condylar bone resorption in a mouse model.

Methods: Female C57BL/6J mice underwent ovariectomy (OVX) to induce estrogen deficiency and ADD was surgically induced for stress.

Importance: Endocrine treatments, such as Tamoxifen (TAM) and/or Aromatase inhibitors (AI), are the adjuvant therapy of choice for hormone-receptor positive breast cancer. These agents are associated with menopausal symptoms, adversely affecting drug compliance. Topical estrogen (TE) has been proposed for symptom management, given its' local application and presumed reduced bioavailability, however its oncological safety remains uncertain.

: This is a prospective study. Atrophic vulvovaginitis (VVA), a prevalent condition resulting from estrogen deficiency after the menopause, is characterized by symptoms such as vaginal dryness, itching, burning, dyspareunia, and urinary discomfort. Standard treatment involves systemic estrogen replacement therapy (HRT) and localized estrogen treatments, such as estriol.

Chronic pain, pain that lasts beyond three months, is a common finding in the elderly. It is often due to musculoskeletal conditions but can be precipitated by other factors as well. While physiological systems decline with aging, chronic pain is influenced by changes in hormone profiles as men and women enter into andropause and menopause, respectively.
