[Topical hormonal treatment in anti-aging of the skin].
Bayerl, C
Der Hautarzt; Zeitschrift fur Dermatologie, Venerologie, und verwandte Gebiete. 2020;(10):786-790
Abstract
Topical hormonal treatment allows anti-aging of the skin when used during and after the menopause without an increase in the blood level of hormones. Natural hormones are only prescribed by medical doctors. In controlled clinical studies versus placebo and application for months, an increase in skin quality parameters, reduction of dryness, increase of glycosaminoglycanes, increase in elastic fibers und increase of collagen precursers and collagen fibers on the mRNA and protein level could be shown, the latter proven by biopsies. Skin with dramatic sun-damage does not respond to this treatment option. Patients with melasma or seborrhoe should not be treated with hormonal topical preparations. Compared to the natural hormones, phytotherapeutics do not bind to hormone receptors in relevant levels. Growth hormones should not be used in anti-aging treatment due to a potential carcinogenic effect.

Abstract
Skin undergoes degenerative changes as it ages, which include the loss of elasticity, reductions in the epidermal thickness and collagen content, elastic fiber degeneration, and increased wrinkling and dryness. Skin aging can be significantly delayed by the administration of estrogen. Estrogen deficiency following menopause results in atrophic skin changes and the acceleration of skin aging. Estrogen administration has positive effects on human skin by delaying or preventing skin aging manifestations, but the use of estrogen replacement is a risk factor for breast and uterine cancer. Phytoestrogens are a large family of plant-derived molecules possessing various degrees of estrogen-like activity; they exhibit agonist or antagonist estrogenic properties depending on the tissue. These molecules could be ideal candidates to combat skin aging and other detrimental effects of hypoestrogenism. In this paper, we review the effects of phytoestrogens on human skin and the mechanisms by which phytoestrogens can alleviate the changes due to aging.

Abstract
BACKGROUND Lower risk of breast cancer has been reported among physically active women, but the risk in women using hormone replacement therapy (HRT) appears to be higher. We quantified the association between physical activity and breast cancer, and we examined the influence that HRT use and other risk factors had on this association. METHODS After a systematic literature search, prospective studies were meta-analysed using random-effect models applied on highest versus lowest level of physical activity. Dose-response analyses were conducted with studies reporting physical activity either in hours per week or in hours of metabolic equivalent per week (MET-h/week). RESULTS The literature search identified 38 independent prospective studies published between 1987 and 2014 that included 116,304 breast cancer cases. Compared to the lowest level of physical activity, the highest level was associated with a summary relative risk (SRR) of 0.88 (95% confidence interval [CI] 0.85, 0.90) for all breast cancer, 0.89 (95% CI 0.83, 0.95) for ER+/PR+ breast cancer and 0.80 (95% CI 0.69, 0.92) for ER-/PR- breast cancer. Risk reductions were not influenced by the type of physical activity (occupational or non-occupational), adiposity, and menopausal status. Risk reductions increased with increasing amounts of physical activity without threshold effect. In six studies, the SRR was 0.78 (95% CI 0.70, 0.87) in women who never used HRT and 0.97 (95% CI 0.88, 1.07) in women who ever used HRT, without heterogeneity in results. Findings indicate that a physically inactive women engaging in at least 150 min per week of vigorous physical activity would reduce their lifetime risk of breast cancer by 9%, a reduction that might be two times greater in women who never used HRT. CONCLUSION Increasing physical activity is associated with meaningful reductions in the risk of breast cancer, but in women who ever used HRT, the preventative effect of physical activity seems to be cancelled out.

ENDOCRINE DILEMMA: Managing menopausal symptoms after breast cancer.
Eden, J
European journal of endocrinology. 2016;(3):R71-7
Abstract
Managing the symptoms of menopause after a diagnosis of breast cancer offers some unique clinical challenges. For some women, vasomotor symptoms can be severe and debilitating, and hormone therapy is at least relatively contraindicated. Non-oestrogen therapies for hot flushes include SSRIs, clonidine, gabapentin and perhaps black cohosh extracts. Vulvovaginal atrophy can usually be alleviated by simple moisturizers, although some may need specialized physiotherapy such as vaginal dilators. In a small number, topical oestrogens may be the only treatment that works. The CO2 laser may be a novel, non-oestrogen therapy to alleviate this unpleasant symptom. Bone loss can be accelerated in some patients on AIs or those who had early menopause induced by chemotherapy.

Evaluation and Treatment of Osteoporosis.
O'Connor, KM
The Medical clinics of North America. 2016;(4):807-26
Abstract
As the population ages, the rates of osteoporotic fractures will increase, with postmenopausal women incurring most of these fractures. Diagnosis and treatment of osteoporosis are extremely important. Dual-energy x-ray absorptiometry scan screening is recommended in all women more than 65 years of age or in women aged 50 to 64 years with certain risk factors. Treatment should be considered if osteoporosis is present, there is a history of fragility fracture, or in the setting of osteopenia plus high risk for fracture.

Hormone Therapy and Other Treatments for Symptoms of Menopause.
Hill, DA, Crider, M, Hill, SR
American family physician. 2016;(11):884-889
Abstract
The results of large clinical trials have led physicians and patients to question the safety of hormone therapy for menopause. In the past, physicians prescribed hormone therapy to improve overall health and prevent cardiac disease, as well as for symptoms of menopause. Combined estrogen/progestogen therapy, but not estrogen alone, increases the risk of breast cancer when used for more than three to five years. Therefore, in women with a uterus, it is recommended that physicians prescribe combination therapy only to treat menopausal symptoms such as vasomotor symptoms (hot flashes) and vaginal atrophy, using the smallest effective dosage for the shortest possible duration. Although estrogen is the most effective treatment for hot flashes, nonhormonal alternatives such as low-dose paroxetine, venlafaxine, and gabapentin are effective alternatives. Women with a uterus who are using estrogen should also take a progestogen to reduce the risk of endometrial cancer. Women who cannot tolerate adverse effects of progestogens may benefit from a combined formulation of estrogen and the selective estrogen receptor modulator bazedoxifene. There is no highquality, consistent evidence that yoga, paced respiration, acupuncture, exercise, stress reduction, relaxation therapy, and alternative therapies such as black cohosh, botanical products, omega-3 fatty acid supplements, and dietary Chinese herbs benefit patients more than placebo. One systematic review suggests modest improvement in hot flashes and vaginal dryness with soy products, and small studies suggest that clinical hypnosis significantly reduces hot flashes. Patients with genitourinary syndrome of menopause may benefit from vaginal estrogen, nonhormonal vaginal moisturizers, or ospemifene (the only nonhormonal treatment approved by the U.S. Food and Drug Administration for dyspareunia due to menopausal atrophy). The decision to use hormone therapy depends on clinical presentation, a thorough evaluation of the risks and benefits, and an informed discussion with the patient.

Systematic reviews. 2016;(1):121
Abstract
BACKGROUND Use of menopausal hormonal therapy (MHT)-containing estrogen and a synthetic progestin is associated with an increased risk of breast cancer. It is unclear if progesterone in combination with estrogen carries a lower risk of breast cancer. Limited data suggest differences between progesterone and progestins on cardiovascular risk factors, including cholesterol and glucose metabolism. Whether this translates to differences in cardiovascular outcomes is uncertain. We conducted a systematic review and meta-analysis to synthesize the existing evidence about the effect of progesterone in comparison to synthetic progestins, each in combination with estrogens, on the risk of breast cancer and cardiovascular events. METHODS We searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Scopus through 17 May 2016 for studies that enrolled postmenopausal women using progesterone vs. synthetic progestins and reported the outcomes of interest. Study selection and data extraction were performed by two independent reviewers. Meta-analysis was conducted using the random effects model. RESULTS We included two cohort studies and one population-based case-control study out of 3410 citations identified by the search. The included studies enrolled 86,881 postmenopausal women with mean age of 59 years and follow-up range from 3 to 20 years. The overall risk of bias of the included cohort studies in the meta-analysis was moderate. There was no data on cardiovascular events. Progesterone was associated with lower breast cancer risk compared to synthetic progestins when each is given in combination with estrogen, relative risk 0.67; 95 % confidence interval 0.55-0.81. CONCLUSIONS Observational studies suggest that in menopausal women, estrogen and progesterone use may be associated with lower breast cancer risk compared to synthetic progestin.

Hormone therapy and clinical and surrogate cardiovascular endpoints in women with chronic kidney disease: a systematic review and meta-analysis.
Ramesh, S, Mann, MC, Holroyd-Leduc, JM, Wilton, SB, James, MT, Seely, EW, Ahmed, SB
Menopause (New York, N.Y.). 2016;(9):1028-37
Abstract
OBJECTIVE Women with chronic kidney disease (CKD) experience kidney dysfunction-mediated premature menopause. The role of postmenopausal hormone therapy (HT) in this population is unclear. We sought to summarize current knowledge regarding use of postmenopausal HT and cardiovascular (CV) outcomes, and established surrogate measures of CV risk in women with CKD. METHODS This is a systematic review and meta-analysis of adult women with CKD. We searched electronic bibliographic databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials) (inception to 2014 December), relevant conference proceedings, tables of contents of journals, and review articles. Randomized controlled trials and observational studies examining postmenopausal HT compared with either placebo or untreated control groups were included. The intervention of interest was postmenopausal HT, and the outcome measures were all-cause and CV mortality, nonfatal CV event (myocardial infarction, stroke), and surrogate measures of CV risk (serum lipids, blood pressure). RESULTS Of 12,482 references retrieved, four randomized controlled trials and two cohort studies (N = 1,666 participants) were identified. No studies reported on CV outcomes or mortality. Compared with placebo, postmenopausal HT was associated with decreased low-density lipoprotein cholesterol (-13.2 mg/dL [95% CI, -23.32 to -3.00 mg/dL]), and increased high-density lipoprotein (8.73 mg/dL [95% CI, 4.72-12.73 mg/dL]) and total cholesterol (7.96 mg/dL [95% CI, 0.07-15.84 mg/dL]). No associations were observed between postmenopausal HT triglyceride levels and blood pressure. CONCLUSIONS Studies examining the effect of postmenopausal HT on CV outcomes in women with CKD are lacking. Further prospective study of the role of postmenopausal HT in this high-risk group is required.

Effects of hormone therapy on blood pressure.
Issa, Z, Seely, EW, Rahme, M, El-Hajj Fuleihan, G
Menopause (New York, N.Y.). 2015;(4):456-68
Abstract
OBJECTIVE Although hormone therapy remains the most efficacious option for the management of vasomotor symptoms of menopause, its effects on blood pressure remain unclear. This review scrutinizes evidence of the mechanisms of action of hormone therapy on signaling pathways affecting blood pressure and evidence from clinical studies. METHODS Comprehensive Ovid MEDLINE searches were conducted for the terms "hypertension" and either of the following "hormone therapy and menopause" or "selective estrogen receptor modulator" from year 2000 to November 2013. RESULTS In vitro and physiologic studies did not reveal a clear deleterious effect of hormone therapy on blood pressure. The effect of oral therapy was essentially neutral in large trials conducted in normotensive women with blood pressure as primary outcome. Results from all other trials had several limitations. Oral therapy had a neutral effect on blood pressure in hypertensive women. Transdermal estrogen and micronized progesterone had a beneficial effect on blood pressure in normotensive women and, at most, a neutral effect on hypertensive women. In general, tibolone and raloxifene had a neutral effect on blood pressure in both hypertensive and normotensive women. CONCLUSIONS Large randomized trials are needed to assess the effect of oral hormone therapy on blood pressure as a primary outcome in hypertensive women and the effect of transdermal preparations on both normotensive and hypertensive women. Transdermal preparations would be the preferred mode of therapy for hypertensive women, in view of their favorable physiologic and clinical profiles. The decision regarding the use of hormone therapy should be individualized, and blood pressure should be monitored during the course of treatment.

Dyslipidemia and cardiovascular disease in women.
Cífková, R, Krajčoviechová, A
Current cardiology reports. 2015;(7):609
Abstract
Cardiovascular disease is the major cause of death in women in developed countries. Dyslipidemia is highly prevalent in women, particularly after the menopause. Elevated low-density lipoprotein cholesterol (LDL-C) has been identified as the key lipid parameter in both genders whereas HDL-cholesterol and triglycerides have been more closely associated, in some studies, with cardiovascular risk in women. Menopause has been shown to be associated with an increase in total and LDL-cholesterol and a decrease in HDL-cholesterol (predominantly in the HDL2 subfraction). Despite its beneficial effects on the lipid profile, hormone replacement therapy is not recommended for primary or secondary prevention of cardiovascular disease in women. The latest meta-analysis of statin trials with gender-specific outcomes showed a similar benefit in women and men. The addition of ezetimibe to simvastatin in patients with acute coronary syndromes showed a further reduction of the primary endpoint in both genders. While there are no gender-related differences in drug treatment of dyslipidemia, current guidelines, to avoid overtreatment, strongly suggest risk estimation before initiating lipid-lowering treatment in women without manifest cardiovascular disease.
