Abstract
Existing hormone replacement therapy for menopause has drawbacks, necessitating new treatment agents. Silkworms have demonstrated estrogenic properties, offering promising alternatives. We assessed the therapeutic effects of freeze-dried silkworm powder (SWP) on menopausal symptoms using an ovariectomized (OVX) mouse model. The experimental design comprised a sham surgery group (Sham), an OVX control group, a low-dose SWP group post-OVX (80 mg/kg, OVX-SWP-L), a high-dose SWP group post-OVX (160 mg/kg, OVX-SWP-H), and an estradiol treatment group post-OVX (OVX-E2). Treatments were administered orally thrice weekly over eight weeks; body weight was monitored weekly. The SWP-treated groups (SWP-L and SWP-H) exhibited less weight gain and increased uterine thickness than the OVX control. Molecular analyses demonstrated that SWP significantly enhanced the phosphorylation of estrogen receptor alpha (ERα), ERK, and AKT. Furthermore, biochemical assays revealed reduced serum neutral lipids across all SWP treatment groups. Notably, HDL-cholesterol levels were significantly increased in the SWP-L group compared to the OVX group. Serum estradiol concentrations were elevated in all the SWP groups, with significant increases in the high-dose group. These findings indicate that SWP may promote the activation of estrogen receptor signaling and improve symptoms associated with estrogen deficiency during menopause.

Beneficial Effects of Flaxseed and/or Mulberry Extracts Supplementation in Ovariectomized Wistar Rats. Nutrients 2022; 14:nu14153238. [PMID: 35956414 PMCID: PMC9370575 DOI: 10.3390/nu14153238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 07/14/2022] [Accepted: 07/14/2022] [Indexed: 11/29/2022] Open
Abstract
Low endogenous estrogen action causes several injuries. Medicinal plants, such as flaxseed and mulberry, contain substances that have been shown to be effective to the organism. The aim was to verify the effects of flaxseed and/or mulberry extracts on ovariectomized Wistar rats. The animals received supplements of extracts and estrogen or saline by gavage for 60 days and were weighed weekly. Vaginal wash, blood, pituitary, uterus, liver, and kidneys were collected. Phenolic compounds and the antioxidant activity of the extracts, lipid profile, uric acid, liver enzymes, and pituitary weight were measured. Histomorphometric for uterine wall and histopathological analyses for liver and kidney were performed. Flaxseed and mulberry extracts showed great antioxidant activity and large amounts of phenolic compounds. The treatment with extracts had less weight gain, increased pituitary weight, the predominance of vaginal epithelial cells, and reduced TC, LDL-c and lipase activity, similar to estrogen animals. Estrogen or flaxseed + mulberry animals reduced VLDL-c and TAG. HDL-c, uric acid, and liver enzymes did not differ. Estrogen or extracts demonstrated trophic action on the endometrial thickness and have not shown hepatotoxicity or nephrotoxicity. We suggested the beneficial effects of flaxseed and mulberry extract as an alternative to reduce and/or prevent the negative effects caused by low estrogenic action.

Abstract
The use of 17 β-estradiol and genistein in women with menopause helps in the reduction of vasomotor symptoms and cognitive improvement. There is evidence on the use of certain flavonoids such as genistein, which has a potentially neuroprotective role in neurodegenerative diseases such as Alzheimer's. Scientific evidence on the effects of phytoestrogens and genistein during menopause and their effect on cognition are scarce, however, in the present review it was found that the intervention with 17 β-estradiol has positive effects on cognition in women with Alzheimer's disease. In addition, the use of genistein, daidzein or any supplement based on isoflavones may influence vasomotor symptoms. 17 β-estradiol supplements in women in early menopause and with some degree of cognitive impairment may have beneficial effects.

Abstract
The objective of this systematic review was to evaluate the influence of the use of phytoestrogens on variations in endometrial thickness in postmenopausal women. Randomized controlled trials were searched in the following electronic databases until March 2020: MEDLINE, Embase, Cochrane Library, Web of Science and LILACS. We used the terms 'phytoestrogens' and 'endometrium' or 'endometrial hyperplasia' to search for relevant trials. The data were analyzed using RevMan 5.3 software. A total of 10 studies involving 1476 patients were included. The difference in endometrial thickness was evaluated in 10 studies, with a total of 805 participants in the phytoestrogen group and 761 in the control group. Such a difference was not significant between groups after 3 months (standardized mean difference [SMD] 0.00, 95% confidence interval [CI] - 0.37 to 0.37; I2 = 63%), 6 months (SMD -0.30, 95% CI -0.79 to 0.19; I2 = 70%), 12 months (SMD -0.02, 95% CI 0.22 to -0.18; I2 = 0%) and 24 months (SMD -0.09, 95% CI -0.25, 0.08; I2 = 0%) of use. Our meta-analysis shows no changes in endometrial thickness in women using phytoestrogens. Evidence is still uncertain owing to the presence of heterogeneity among the studies currently available, whose reported outcomes cover a period between 3 and 6 months.

Abstract
INTRODUCTION Genitourinary menopause syndrome (SGUM) is defined as a set of symptoms associated with a decrease of estrogen and other sexual steroids during menopause. The main symptoms are vulvovaginal (dryness, burning, itching), sexual (dyspareunia), and urinary (urinary infections, pollakiuria, nycturia, pain, urinary incontinence by urgenturia). SGUM leads to an alteration of the quality of life, and affects especially women's sexuality. OBJECTIVE The objective of this review was to elaborate guidelines for clinical practice regarding the management of SGUM in postmenopausal women, and in particular, in women with a history of breast cancer, treated or not with hormone therapy. MATERIALS AND METHODS A systematic review of the literature on SGUM management was conducted on Pubmed, Medline and Cochrane Library. Recommendations from international scholarly societies were also taken into account: International Menopause Society (IMS) https://www.imsociety.org, The North American Menopause Society (NAMS) https://www.menopause.org, Canadian Menopause Society https://www.sigmamenopause.com, European Menopause and Andropause Society (EMAS) https://www.emas-online.org, International Society for the Study of Women's Sexual Health (ISSWSH) https://www.isswsh.org. RESULTS Vaginal use of lubricants, moisturizers and hyaluronic acid improves the symptoms of SGUM and may be offered to all patients. For postmenopausal women, local estrogen will be preferred to the oral route because of their safety and efficacy on all symptoms of SGUM during low-dose use. Prasterone is a local treatment that can be proposed as an effective alternative for the management of dyspareunia and sexual function disorder. Current data on oral testosterone, tibolone, oral or transdermal DHEA and herbal medicine are currently limited. Ospemifène, which has shown a significant improvement in sexual symptoms, is not currently marketed in France. In the particular case of women with a history of breast cancer, non-hormonal regimens are a first-line therapy. Current data on the risk of breast cancer recurrence when administering low-dose local estrogen are reassuring but do not support a conclusion that this treatment is safe. CONCLUSION SGUM is a common symptom that can affect the quality of life of postmenopausal women. A treatment should be systematically proposed. Local non-hormonal treatment may be offered in all women. Local low-dose estrogen therapy and Prasterone has shown an interest in the management of symptoms. In women before a history of breast cancer, local non-hormonal treatment should be offered first-line. The safety of low-dose local estrogen therapy and Prasterone cannot be established at this time. Other alternatives exist but are not currently recommended in France due to lack of data.

Abstract
OBJECTIVE Menopause symptoms affect the various dimensions of women's lives and they can lead to reduction of their quality of life. Phytoestrogens can be used as an approach to diminish these symptoms. The aim of this systematic review was to investigate the effect of phytoestrogens on the treatment of urogenital menopause symptoms. STUDY DESIGN PubMed, EMBASE, Web of Science, Cochrane library,Scopus and ProQuest were systematically searched from 2000-2020. All randomized clinical trials were included. The quality of the selected papers was evaluated by the CONSORT checklist. RESULTS 33 eligible high-quality papers were reviewed. Various forms of phytoestrogens such as Pueraria Mirifica, fennel, Hop plant(Humuluslupulus L.), Glycine Max (L.) Merr, soy, red clover, black cohosh, ginsing, cimicifugaracemosa, genistein, diadzein, glycitein and isoflavone in the form of oral capsules and pill, food supplement, enriched powder, vaginal gel, cream and suppository could improve menopausal urogenital symptoms. The recovery rate in vaginal use of these phytoestrogens was greater than other consumptions. CONCLUSIONS After using a variety of phytoestrogens in different forms indicators of urogenital atrophy and urinary disorders improved and women's sexual function improved after treatment. The use of phytoestrogens as a safe, low-risk compared to hormone therapy and almost accessible method for women can relieve urogenital symptoms and promote the sexual satisfaction and quality of life.

Abstract
BACKGROUND Menopause and estrogen deprivation cause a rise in the number of urogenital tract complaints. OBJECTIVE This study was conducted to assess the effectiveness of ginseng on genitourinary syndrome. METHODS This randomized trial was conducted on 60 postmenopausal women with genitourinary syndrome. The participants were randomly allocated to ginseng and placebo groups twice daily for 4 weeks. Vaginal maturation index and vaginal pH were evaluated before and 4 weeks after intervention as the primary outcomes. Also, the atrophic vaginitis and incontinence questionnaires were completed before and after intervention as the secondary outcomes. The safety of intervention was assessed by the side effects checklist. RESULTS No significant differences were observed between the 2 groups in objective symptoms after the intervention, but the difference was statistically significant (p < 0.001) in terms of subjective symptoms of atrophic vaginitis. One case of insomnia and palpitation and 2 cases of hot flashes were reported in the intervention group, and 1 case of gastric discomfort and change in urine appearance was reported in the placebo group. CONCLUSION Ginseng only improved the patient-assessed symptoms and had no significant effect on the clinician-assessed outcomes. Further studies are required to determine the precise pharmacological mechanisms of ginseng on genitourinary syndrome.

Abstract
The menopausal transition, or perimenopause, is characterized by menstrual irregularities, vasomotor symptoms, sleep disturbances, mood symptoms, and urogenital tract atrophy. These changes can also affect the quality of life and one’s self-esteem. Hormone replacement therapy (HRT) is considered the best option to achieve therapeutic relief of different menopausal symptoms but is usually restricted to moderate or severe symptoms. Moreover, many women refuse HRT for a variety of reasons concerning the fear of cancer and other adverse effects. According to these considerations, new topics are emerging: Dissatisfaction with drug costs and conventional healthcare, desire for personalized medicines, and the public perception that “natural is good”. In this context, nonhormonal therapies are mostly evolving, and it is not unusual that women often request a “natural” approach for their symptoms. The aim of this study is to investigate nonhormonal therapies that have been identified to reduce the menopausal symptoms.

DETERMINATION OF THE BIOADHESION INDICATORS OF VAGINAL GEL WITH RESVERATROL AND HYALURONIC ACID. EUREKA: HEALTH SCIENCES 2019. [DOI: 10.21303/2504-5679.2019.00880] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/20/2022] Open
Abstract
Aim. The purpose of the work is to determine the bioadhesion indices of vaginal gel with resveratrol and hyaluronic acid, as well as the choice of the type and content of mucoadhesives in the composition.
Materials and methods. As research objects samples of gels with different mucoadhesives in the composition were used. Among used mucoadhesives were: sodium alginate (FMC BioPolimer AS, Norway), methyl cellulose (Shin Etsu, Germany), Methocel – methyl cellulose with hydroxypropylmethyl cellulose (Dow Pharmaceutical Sciences, USA), OraRez® W-100L16 – vinyl methyl ether and maleic anhydride copolymer (BOAI, China). As a comparison drug, vaginal gel "Gynodec" (Yuriya-Pharm) was used. During the study, the rate of gel distribution, the degree of deformation under the influence of mechanical forces, the degree of the gel fixation on the surface of the mucosa and the adhesion ability of the samples have been determined.
Results. The study has determined that sample No. 2 with sodium alginate has the highest distribution rate, which was 1.56 cm/min. The study of the fixation of samples on the surface of the model of the mucous was performed by the method of flow. The results have showed that the sample with sodium alginate has the closest value to the reference drug. The adhesive ability of samples with different sodium alginate contents was determined. The tensimetric study has found that at a concentration of 0.5 %, the force required to separate the surface is 6158 Pa.
Conclusions. On the basis of the complex of physico-chemical studies, bioadhesion indicators of vaginal gel with resveratrol, depending on the type and concentration of mucoadhesives have been determined. According to the distribution parameters on the surface of the genital mucosa model, it has been found that the best properties compared with other types of mucoadhesives has a sample containing sodium alginate. The study by means of a strain gauge has found that the addition of sodium alginate at a concentration of 0.5 % would provide a satisfactory adhesive ability of the vaginal gel.
