240 The effect of female hormonal changes on psoriasis
While studies have noted improvement of psoriasis in most women during pregnancy with subsequent postpartum deterioration, there is little data on the impact of other hormonal events. Moreover, there have been changes in hormonally-based therapies in the last 20 years. We surveyed a large number and diversity of women on the effect that hormonal variations (menarche, menses, exposure to hormonal contraception, infertility therapy, pregnancy, menopause, and hormone replacement therapy) have had on their psoriasis.

Menopause and Rheumatic Disease
Menopause occurs naturally in women at about 50 years of age. There is a wealth of data concerning the relationship of menopause to systemic lupus erythematosus, rheumatoid arthritis, and osteoarthritis; there are limited data concerning other rheumatic diseases. Age at menopause may affect the risk and course of rheumatic diseases. Osteoporosis, an integral part of inflammatory rheumatic diseases, is made worse by menopause. Hormone replacement therapy has been studied; its effects vary depending on the disease and even different manifestations within the same disease. Cyclophosphamide can induce early menopause, but ther...

Lost in menopausal transition: the timing of atherosclerosis prevention in women.
Abstract Advanced atherosclerotic changes can often resist even to very aggressive treatment. Although basic mechanisms of its origin and development are known, some important steps in this process are still waiting for more detailed explanation. Therefore, in addition to already proved aggressive lowering of LDL cholesterol, appropriate timing of atherosclerosis treatment is of the essence. Revealing different stages of atherosclerotic process, less or more sensitive to treatment is of primary importance; however, its detection is complicated by several facts including not exactly identifiable periods of quiescen...

Gynecologic Health Issues in Patients With Turner Syndrome: A Survey Study
Adolescents with Turner Syndrome (TS) face almost certain premature ovarian failure which may result in increased risk of osteoporosis and in infertility. However, although hormone replacement therapy (HRT) is crucial for maintenance of bone mineral density (BMD) and osteoporosis prevention, women with Turner ’s syndrome may have variable knowledge of the importance of HRT and may have variable compliance. In addition, advances in assisted reproductive technology such as egg freezing and oocyte cryopreservation have now made fertility preservation an option for some adolescents with TS.

Abstract 226: Strokes Worse in Women at 24 hours but Severity Reduced in Younger Women With Hormone Therapy [Session Title: Poster Session II]
Conclusion: Women in this study had more severe 24 hour AIS outcomes than men but this improved with HRT use in women younger than 80 years. This cannot be fully explained by age differences as there could be other underlying factors. Improving 24 hour NIHSS may correctly predict later outcomes following AIS. Further study of HRT use in AIS outcomes is justified. (Source: Circulation: Cardiovascular Quality and Outcomes)

(115) Protective role of progesterone against allodynia in rats with persistent temporomandibular joint inflammation
Temporomandibular joint disorder (TMD), caused by injury, stress, or systemic disorders, is associated with pain and inflammation in the joint (TMJ) and muscles involved in mastication. TMD affects men and women, but is more prevalent in woman from the onset of puberty until post-menopause when symptoms diminish. After menopause, some women undergo hormone replacement therapy (HRT), which has been linked to the reemergence of TMD pain. Progesterone attenuates inflammation through reduced expression of pro-inflammatory genes and attenuates allodynia in rodent pain models. (Source: The Journal of Pain)

Therapeutic potential and outlook of alternative medicine for osteoporosis.
Abstract Osteoporosis, a bone disease resulting in loss of bone density and microstructure quality, is often associated with fragility fractures, and the latter imposes a great burden on the patient and society. Although there are several different treatments available for osteoporosis such as hormone replacement therapy, bisphosphonates, Denosumab, and parathyroid hormone some concern has been raised regarding the inherent side effects of their long term use. It would be of great relevance to search for alternative natural compounds, which could complementarily overcome the limitations of the currently available ...

Endometriosis after menopause: physiopathology and management of an uncommon condition.
Abstract Endometriosis is a hormone-dependent inflammatory disease that is usually characterized by infertility and pain symptoms. This disease mainly occurs during the reproductive years and is rarely diagnosed after menopause. We discuss the physiopathology of this condition after menopause as well as treatment options and the risk of malignant transformation. Occurrence or progression of postmenopausal endometriosis lesions could be related to extra-ovarian production of estrogen by endometriosis lesions and adipose tissue, which becomes the major estrogen-producing tissue after menopause. Postmenopausal women ...

The evidence base for HRT: what can we believe?
Abstract Prior to the unexpected early termination of the Women's Health Initiative (WHI) trial of continuous conjugated equine estrogens (CEE) and medroxyprogesterone acetate (MPA), the prevailing view was that hormone replacement therapy (HRT) was a low-risk intervention with immediate value for symptom relief in recently menopausal women, and that it probably conferred long-term protection against the major chronic diseases that affect women after menopause. Rather than replicating prior studies, the WHI was designed to test whether the beneficial associations consistently seen in women starting HRT near menopa...

Progesterone Increased β-endorphin Innervation of the Locus Coeruleus, but Ovarian Steroids had no Effect on Noradrenergic Neurodegeneration.
In conclusion, we found that HRT increases the inhibitory influence of β-endorphin in the LC, which could, in turn, contribute to reduce anxiety and increase stress resilience. In addition, we did not find compelling evidence of neurodegeneration or neuroprotection by HRT in the LC of Rhesus monkeys.

Leukocyte and Skeletal Muscle Telomere Length and Body Composition in Monozygotic Twin Pairs Discordant for Long-term Hormone Replacement Therapy.
Abstract Estrogen-based hormone replacement therapy (HRT) may be associated with deceleration of cellular aging. We investigated whether long-term HRT has effects on leukocyte (LTL) or mean and minimum skeletal muscle telomere length (SMTL) in a design that controls for genotype and childhood environment. Associations between telomeres, body composition, and physical performance were also examined. Eleven monozygotic twin pairs (age 57.6 ± 1.8 years) discordant for HRT were studied. Mean duration of HRT use was 7.3 ± 3.7 years in the user sister, while their co-twins had never used HRT. LTL was measured by qPCR ...

Dietary nitrite reverses features of postmenopausal metabolic syndrome induced by high fat diet and ovariectomy in mice.
We examined the effect of dietary nitrite on mice model with postmenopausal metabolic syndrome induced by ovariectomy (OVX) with high fat diet (HF). C57BL/6 female mice were divided into five groups, sham+normal fat diet (NF), sham+ HF, OVX+HF without or with sodium nitrite (50mg and 150mg/L) in drinking water. Daily food intake and weekly body weight were monitored for 18 weeks. OVX and HF significantly reduced plasma levels of nitrate/nitrite (NOx), and developed obesity with visceral hypertrophic adipocytes, and increased transcriptional levels of monocyte chemoattractant protein-1 (MCP-1), tumor necrotizing factor-α (...
