Abstract
Probiotics, live microorganisms that confer health benefits to the host when administered in adequate amounts, have gained considerable attention for their potential role in maintaining women's health. This overview summarizes key clinical findings on the beneficial effects of probiotics in various aspects of women's health. Probiotics, particularly Lactobacillus species, contribute to vaginal health by promoting a balanced vaginal microbiome to prevent infections and maintain an acidic environment. In gynecologic conditions, probiotics show potential in preventing and managing bacterial vaginosis, vulvovaginal candidiasis, and sexually transmitted infections. Probiotic supplementation has also been associated with improvements in metabolic parameters and menstrual irregularities in polycystic ovary syndrome patients. During pregnancy, probiotics may be helpful in reducing the risk of gestational diabetes, maternal group B streptococcal colonization, obstetric anemia, and postpartum mastitis. In recent years, the potential role of probiotics in the prevention and management of gynecologic cancer has gained attention. Further research is needed to better understand the specific mechanisms and determine the optimal Lactobacillus strains and dosages regimens for gynecologic cancer prevention and therapy. In conclusion, probiotics offer a non-invasive and cost-effective approach to support women's health and prevent obstetric and gynecologic complications.

Therapeutic Choices for Genitourinary Syndrome of Menopause (GSM) in Breast Cancer Survivors: A Systematic Review and Update. Pharmaceuticals (Basel) 2023; 16:ph16040550. [PMID: 37111307 PMCID: PMC10142093 DOI: 10.3390/ph16040550] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 03/21/2023] [Accepted: 03/29/2023] [Indexed: 04/09/2023] Open
Abstract
(1) Background: Genitourinary syndrome of menopause (GSM) is a medical condition that can affect breast cancer survivors (BCS). This is a complication that often can occur as a result of breast cancer treatment, causing symptoms such as vaginal dryness, itching, burning, dyspareunia, dysuria, pain, discomfort, and impairment of sexual function. BCS who experience these symptoms negatively impact multiple aspects of their quality of life to the point that some of them fail to complete adjuvant hormonal treatment; (2) Methods: In this systematic review of the literature, we have analyzed possible pharmacological and non-pharmacological treatments for GSM in BCS. We reviewed systemic hormone therapy, local hormone treatment with estrogens and androgens, the use of vaginal moisturizers and lubricants, ospemifene, and physical therapies such as radiofrequency, electroporation, and vaginal laser; (3) Results: The data available to date demonstrate that the aforementioned treatments are effective for the therapy of GSM and, in particular, vulvovaginal atrophy in BCS. Where possible, combination therapy often appears more useful than using a single line of treatment; (4) Conclusions: We analyzed the efficacy and safety data of each of these options for the treatment of GSM in BCS, emphasizing how often larger clinical trials with longer follow-ups are needed.

Abstract
Estrogens locally delivered to the vagina by tablets, capsules, rings, pessaries, and creams are the most common and highly recommended platforms to treat the genitourinary syndrome of menopause (GSM). Estradiol, an essential estrogen, is routinely administered alone, or in combination with progestins, to effectively alleviate the symptoms associated with moderate to severe menopause when non-pharmacological interventions are not indicated. Since the risk and side effects of estradiol use depends on the administered amount and duration of use, the lowest effective dose of estradiol is recommended when long-term treatment is required. Although there is a wealth of data and literature comparing vaginally administered estrogen-containing products, there is a lack of information revealing the effect of the delivery system used and formulation constituent's attributes on the efficacy, safety, and patient acceptability of these dosage forms. This review therefore aims to classify and compare various designs of commercially available and non-commercial vaginal 17β-estradiol formulations and analyze their performance in terms of systemic absorption, efficacy, safety, and patient satisfaction and acceptance. The vaginal estrogenic platforms included in this review are the currently marketed and investigational 17β-estradiol tablets, softgel capsules, creams, and rings for the treatment of GSM, based on their different design specifications, estradiol loads, and materials used in their preparation. Additionally, the mechanisms of the effects of estradiol on GSM have been discussed, as well as their potential impact on treatment efficacy and patient compliance.

Abstract
This guidance refers to urogenital atrophy, a chronic and progressive condition due to estrogen deficiency, most commonly associated with the menopause. There is a potential negative impact on all urogenital tissue quality including the vulva, vagina, bladder and urethra. Symptoms may not become apparent for several years after the menopause and therefore any association is lost, with women accepting symptoms as a normal part of the aging process. There may be reluctance to discuss symptoms with a clinician and this is likely to be linked with under diagnosis and under treatment. Urogenital atrophy has been described as a silent epidemic with lack of awareness affecting an accurate diagnosis and access to treatment. Whilst vaginal estrogen (also referred to as local estrogen) therapy is the best-known treatment, newer drugs and interventions are now available.

Abstract
INTRODUCTION AND HYPOTHESIS Recurrent urinary tract infections (rUTIs) are commonly encountered in postmenopausal women. Optimal non-antimicrobial prophylaxis for rUTIs is an important health issue. The aim of this study was to evaluate the use of estrogen in the prevention of rUTIs versus placebo. METHODS Eligible studies published up to December 2019 were retrieved through searches of MEDLINE, Embase, and Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. We included randomized controlled trials of estrogen therapies versus placebo regarding the outcomes of preventing rUTIs. Changes in vaginal pH and estrogen-associated adverse events were also analyzed. RESULTS Eight studies including 4702 patients (2367 who received estrogen and 2335 who received placebo) were identified. Five studies including 1936 patients evaluated the use of vaginal estrogen, which resulted in a significant reduction in rUTIs (relative risk, 0.42; 95% CI, 0.30-0.59). Three studies including 2766 patients evaluated the outcomes of oral estrogen in the prevention of UTIs and showed no significant difference in the number of rUTIs compared to treatment with placebo (relative risk, 1.11; 95% CI, 0.92-1.35). Two studies reviewed changes in vaginal pH and showed a lower pH (mean difference, -1.81; 95% CI, -3.10--0.52) after vaginal estrogen therapy. Adverse events associated with vaginal estrogen were reported, including vaginal discomfort, irritation, burning, and itching. There was no significance increase in the vaginal estrogen group (relative risk, 3.06; 95% CI, 0.79-11.90). CONCLUSIONS Compared with placebo, vaginal estrogen treatment could reduce the number of rUTIs and lower the vaginal pH in postmenopausal women.

Abstract
The constantly changing landscape regarding menopausal hormone therapy (MHT) has been challenging for providers caring for menopausal women. After a decade of fear and uncertainty regarding MHT, reanalysis of the Women’s Health Initiative data and the results of recent studies have provided some clarity regarding the balance of risks and benefits of systemic MHT. Age and years since menopause are now known to be important variables affecting the benefit-risk profile. For symptomatic menopausal women who are under 60 years of age or within 10 years of menopause, the benefits of MHT generally outweigh the risks. Systemic MHT initiated early in menopause appears to slow the progression of atherosclerotic disease, thereby reducing the risk of cardiovascular disease and mortality. During this window of opportunity, MHT might also provide protection against cognitive decline. In older women and women more than 10 years past menopause, the risk-benefit balance of MHT is less favorable, particularly with regard to cardiovascular risk and cognitive impairment. For women entering menopause prematurely (<40 years), MHT ameliorates the risk of cardiovascular disease, osteoporosis, and cognitive decline. Nonoral administration of estrogen offers advantages due to the lack of first-pass hepatic metabolism, which in turn avoids the increased hepatic synthesis of clotting proteins, C-reactive protein, triglycerides, and sex hormone-binding globulin. The duration of combined MHT use is ideally limited to less than 5 years because of the known increase in breast cancer risk after 3–5 years of use. Limitations to use of estrogen only MHT are less clear, since breast cancer risk does not appear to increase with use of estrogen alone. For women under the age of 60 years, or within 10 years of onset of natural menopause, MHT for the treatment of bothersome menopausal symptoms poses low risk and is an acceptable option, particularly when nonhormonal management approaches fail.

Estrogenic action on innate defense mechanisms in the urinary tract. Maturitas 2013; 77:32-6.

Abstract
Clinical data suggest an impact of estrogen on the pathogenesis of urinary tract infections (UTI). In particular, women after menopause often suffer from recurrent UTI, characterized by at least three acute UTI episodes within a year. Aside from bacterial factors promoting persistence within the urinary bladder, the low estrogen levels induce structural and chemical changes in the urogenital tract which facilitate UTI. Increased residual urine volume and changes in the vaginal microflora are well documented risk factors. Local supplementation with estrogen can at least partly reverse these changes. Treatment allows the re-establishment of a lactobacilli-dominated vaginal microflora and improves epithelial differentiation and integrity in the urogenital tract. This estrogenic effect on the epithelium is marked by an increased production of antimicrobial peptides and a tighter intercellular connection, preventing bacteria from reaching cells where they can hide and later emerge and cause a new infection. Estrogen in the dosages and applications used to date is considered safe for the endometrium in the majority of women. Based on the actions and safety of estrogen, local supplementation thus offers a treatment option for postmenopausal women suffering from recurrent UTI.
