Estrogen and testosterone supplementation improves tendon healing and functional recovery after rotator cuff repair.

Failure of healing after rotator cuff repair (RCR) is common. The purpose of the current study was to evaluate the effect of systemic estrogen or testosterone supplementation on tendon healing after RCR. Seventy-two adult male mice were utilized for all experiments. The supraspinatus tendon was transected and repaired with 6-0 Prolene suture on the left shoulder of 51 animals. Mice were segregated into three groups postoperative: (1) vehicle group (VG; n = 18), (2) estrogen group (EST; n = 17), and (3) testosterone group (TST; n = 16). An unrepaired control group (unrepaired, n = 21) did not have surgery. Utilizing these animals, histological analysis, activity testing, biomechanical testing and RNA sequencing (RNA-seq) was performed. At 8 weeks post-RCR, TST, and EST supplementation improved the overall histologic structure of the repaired enthesis site. No differences in ultimate failure loads or stiffness were detected between VG, EST, and TST groups after biomechanical testing. RCR caused a reduction in wheel activity compared to unrepaired controls and supplementation with TST restored wheel activity. RNA-seq analysis indicated that estrogen and testosterone regulated different pathways associated with enthesis healing, including a suppression of inflammatory signaling. Supplementation with sex hormones improved the structure of the repaired tendon enthesis and significantly regulated expression of diverse pathways regulating multiple biological processes. Testosterone administration following RCR restored wheel activity without having a detrimental impact on biomechanical strength. Future human studies of sex hormone supplementation after RCR are warranted as supplementation in an animal model may improve tendon enthesis healing.

Use of Fermented Red Clover Isoflavones in the Treatment of Overactive Bladder in Postmenopausal Women: A Randomized, Double-Blinded, Placebo-Controlled Trial.

Postmenopausal women are at risk of developing an overactive bladder (OAB). Conventional vaginal estrogen has shown promise for symptom relief. Isoflavones have proven effective as an alternative to estrogen treatment against menopause-related symptoms. However, its effect on OAB symptoms has not been studied. This study investigates if fermented red clover isoflavones reduce OAB symptoms in postmenopausal women. In this randomized, double-blinded, placebo-controlled trial, women were administered red clover extract (RCE) or a placebo twice daily for three months. Women filled out the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB) and Urinary Incontinence Short Form (ICIQ-UI-SF), together with a fluid intake and voiding diary. A total of 33 women (16 in the RCE group and 17 in the placebo group) were included in the analysis. Baseline demographics and OAB characteristics were comparable across groups. Intake of RCE did not lead to significant relief in most urinary bladder symptom measures, although a significant reduction in the bother of urinary urgency (p = 0.033) and a tendency towards a decreased ICIQ-OAB score were observed (p = 0.056). In contrast, the placebo exhibited a significant decrease in the ICIQ-OAB score (p = 0.021) and in some diary outcomes. We found that an intake of isoflavones did not relieve OAB symptoms in postmenopausal women.

Phytoestrogen-Based Hormonal Replacement Therapy Could Benefit Women Suffering Late-Onset Asthma.

It has been observed that plasmatic concentrations of estrogens, progesterone, or both correlate with symptoms in asthmatic women. Fluctuations in female sex steroid concentrations during menstrual periods are closely related to asthma symptoms, while menopause induces severe physiological changes that might require hormonal replacement therapy (HRT), that could influence asthma symptoms in these women. Late-onset asthma (LOA) has been categorized as a specific asthmatic phenotype that includes menopausal women and novel research regarding therapeutic alternatives that might provide relief to asthmatic women suffering LOA warrants more thorough and comprehensive analysis. Therefore, the present review proposes phytoestrogens as a promising HRT that might provide these females with relief for both their menopause and asthma symptoms. Besides their well-recognized anti-inflammatory and antioxidant capacities, phytoestrogens activate estrogen receptors and promote mild hormone-like responses that benefit postmenopausal women, particularly asthmatics, constituting therefore a very attractive potential therapy largely due to their low toxicity and scarce side effects.

Recurrent urinary tract infection management and prevention techniques among a population-based cohort of women.

INTRODUCTION: Recurrent urinary tract infection (rUTI), defined as three or more UTIs in 12 months, has psychological, physical, and financial burden. Many women with rUTI are not satisfied with care and report only starting preventative measures after several infections. The goal of this study is to elucidate current UTI management trends and the implementation of UTI prevention strategies. METHODS: A web-based study was sent to a national sample of adult women enrolled in ResearchMatch.org. Women were recruited to participate if they had a self-reported UTI in the past 12 months. RESULTS: Of the 755 subjects, nearly 30% reported rUTI. Among women with rUTI, more than 50% reported being peri- or postmenopausal, and two-thirds reported vaginal symptoms. 15.8% of women with rUTI reported dissatisfaction with care versus 7.9% of women without rUTI. Most women see their primary care physician for UTI management and only 26% of women with rUTI follow with a urologist. More than 65% of women increase their fluid intake, wipe from front to back, and urinate after sexual activity to prevent UTIs. Significantly more women with rUTI use transvaginal estrogen, cranberry extract, and low-dose prophylactic antibiotics. These interventions appear to be driven by urologists. CONCLUSION: Most women who have had a UTI in the last 12 months implement lifestyle changes to prevent future infections. Most women see their PCP for UTI management and women with rUTI are twice as likely to report dissatisfaction with care. Despite urologists optimizing medical rUTI prevention, they appear to be underutilized.

Eicosapentaenoic acid supplementation modulates the osteoblast/osteoclast balance in inflammatory environments and protects against estrogen deficiency-induced bone loss in mice.

BACKGROUND: An imbalance of osteoblasts (OBs) and osteoclasts (OCs) in a chronic inflammatory microenvironment is an important pathological factor leading to osteoporosis. Eicosapentaenoic acid (EPA) has been shown to suppress inflammation in macrophages and adipocytes. However, the effect of EPA on OBs and OCs has yet to be fully elucidated. AIMS: We explored the roles of EPA in the differentiation of OBs and OCs, as well as the coupling between OBs and OCs in an inflammatory microenvironment. The effects of EPA on estrogen deficiency-induced osteoporosis were also evaluated. METHODS: Mouse bone marrow mesenchymal stem cells (mBMSCs) and mouse bone marrow-derived macrophages (mBMMs) were used for in vitro OBs and OCs differentiation. TNF-α was used to create an inflammatory microenvironment. We examined the effects of EPA on osteoblastogenesis in the absence or presence of TNF-α and collect OBs' culture medium as the conditioned medium (CM). Then we examined the effects of EPA and CM on RANKL-induced osteoclastogenesis. The in vivo effects of EPA were determined using an ovariectomized (OVX) mouse model treated with EPA or vehicle. RESULTS: High-dose EPA was shown to promote osteoblastogenesis in an inflammatory environment in vitro, as well as upregulate expression of OBs-specific proteins and genes. ARS and ALP staining also showed that high-dose EPA-treated groups restored mBMSCs' impaired osteogenic capacity caused by TNFa. Mechanistically, EPA suppressed the NF-κB pathway activated by TNF-α in mBMSCs and rescued TNF-α-mediated inhibition of osteoblastogenesis. EPA was also shown to inhibit expression of RANKL and decrease the RANKL/OPG ratio in OBs in an inflammatory environment. CM from TNF-α-stimulated OBs promoted osteoclastogenesis of mBMMs; EPA-treated CM prevented this. In the OVX mouse model, EPA supplementation prevented bone loss in an estrogen deficiency-induced inflammatory environment. CONCLUSIONS: EPA was demonstrated for the first time to restore mBMSCs' impaired osteogenic capacity caused by TNFa-induced inflammation and rescue the OBs/OCs balance via regulation of RANKL and OPG expression in OBs. EPA showed a remarkable ability to prevent bone loss in OVX mice, suggesting a potential application of EPA in postmenopausal osteoporosis.

Nonestrogen Therapies for Treatment of Genitourinary Syndrome of Menopause: A Systematic Review.

OBJECTIVE: To systematically review the literature and provide clinical practice guidelines regarding various nonestrogen therapies for treatment of genitourinary syndrome of menopause (GSM). DATA SOURCES: MEDLINE, EMBASE, ClinicalTrials.gov , and Cochrane databases were searched from inception to July 2021. We included comparative and noncomparative studies. Interventions and comparators were limited to seven products that are commercially available and currently in use (vaginal dehydroepiandrosterone [DHEA], ospemifene, laser or energy-based therapies, polycarbophil-based vaginal moisturizer, Tibolone, vaginal hyaluronic acid, testosterone). Topical estrogen, placebo, other nonestrogen products, as well as no treatment were considered as comparators. METHODS OF STUDY SELECTION: We double-screened 9,131 abstracts and identified 136 studies that met our criteria. Studies were assessed for quality and strength of evidence by the systematic review group. TABULATION, INTEGRATION, AND RESULTS: Information regarding the participants, details on the intervention and comparator and outcomes were extracted from the eligible studies. Alternative therapies were similar or superior to estrogen or placebo with minimal increase in adverse events. Dose response was noted with vaginal DHEA and testosterone. Vaginal DHEA, ospemifene, erbium and fractional carbon dioxide (CO 2 ) laser, polycarbophil-based vaginal moisturizer, tibolone, hyaluronic acid, and testosterone all improved subjective and objective signs of atrophy. Vaginal DHEA, ospemifene, tibolone, fractional CO 2 laser, polycarbophil-based vaginal moisturizer, and testosterone improved sexual function. CONCLUSION: Most nonestrogen therapies are effective treatments for the various symptoms of GSM. There are insufficient data to compare nonestrogen options to each other.

Effectiveness of oestrogen pretreatment in patients with expected poor ovarian response (POSEIDON groups 3 and 4) undergoing GnRH antagonist protocol: study protocol for a randomised controlled trial.

INTRODUCTION: Women characterised by diminished ovarian reserve are considered to have poor ovarian response (POR) according to Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number (POSEIDON) criteria. Patients in this population often have a poor prognosis for treatment with assisted reproductive technology. In previous studies, oestrogen pretreatment before ovarian stimulation has been shown to have a beneficial effect. However, recent studies presented conflicting conclusions. This study aims to evaluate the effectiveness of oestrogen pretreatment in patients with expected POR (POSEIDON groups 3 and 4) undergoing gonadotrophin releasing hormone antagonist (GnRH-ant) protocol. METHODS AND ANALYSIS: A prospective superiority randomised parallel controlled trial will be conducted at a tertiary university-affiliated hospital. A total of 316 patients will be randomly divided into two groups at a ratio of 1:1. In the intervention group, oral oestrogen pretreatment will be administered from day 7 after ovulation until day 2 of the next menstrual cycle. Afterwards, a flexible GnRH-ant protocol will be initiated. The control group will receive no additional intervention beyond routine ovarian stimulation. The primary outcome is the number of oocytes retrieved. Secondary outcomes include the total number of retrieved metaphase II oocytes, average daily dose of gonadotropin, total gonadotropin dose and duration of ovarian stimulation, cycle cancellation rate, top quality embryos rate, blastocyst formation rate, embryo implantation rate, clinical pregnancy rate, early miscarriage rate and endometrial thickness on trigger day. All data will be analysed according to the intention-to-treat and per-protocol principles. ETHICS AND DISSEMINATION: The ethical approval has been confirmed by the reproductive ethics committee of the affiliated hospital of Shandong University of Traditional Chinese Medicine (SDUTCM/2022.9.20). In addition, written informed consent will be obtained from all the participants before the study. The results will be disseminated via publications. TRIAL REGISTRATION NUMBER: ChiCTR2200064812.

Endometriosis Treatment: Role of Natural Polyphenols as Anti-Inflammatory Agents.

Endometriosis is an estrogen-dependent common chronic inflammatory disease defined by the presence of extrauterine endometrial tissue that promotes pelvic pain and fertility impairment. Its etiology is complex and multifactorial, and several not completely understood theories have been proposed to describe its pathogenesis. Indeed, this disease affects women's quality of life and their reproductive system. Conventional therapies for endometriosis treatment primarily focus on surgical resection, lowering systemic levels of estrogen, and treatment with non-steroidal anti-inflammatory drugs to counteract the inflammatory response. However, although these strategies have shown to be effective, they also show considerable side effects. Therefore, there is a growing interest in the use of herbal medicine for the treatment of endometriosis; however, to date, only very limited literature is present on this topic. Polyphenols display important anti-endometriotic properties; in particular, they are potent phytoestrogens that in parallel modulates estrogen activity and exerts anti-inflammatory activity. The aim of this review is to provide an overview on anti-inflammatory activity of polyphenols in the treatment of endometriosis.

Tranexamic Acid in Facial Feminization Surgery: Quantifying a High-risk Setting With Exogenous Estrogen Supplementation.

Tranexamic acid (TXA) has been increasingly utilized in orthognathic surgery, aesthetic surgery, and craniofacial surgery. However, the risk of increasing venous thromboembolic events (VTE) must be carefully considered as TXA is a prothrombotic agent. Our study aimed to investigate the safety of TXA in the setting of facial feminization surgery. These patients are at an elevated risk for VTE at baseline given their uniform history of exogenous estrogen supplementation. A retrospective review of all patients that underwent facial feminization surgery at our medical center between December 2015 and September of 2022 was performed. Demographic information, procedure type, Caprini scores, hematoma rate, VTE rate, estimated blood loss, and operative time were all studied. Unpaired t tests were used to compare patients that received TXA and those who did not. In total, there were 79 surgeries performed during our study period. There were 33 surgeries (41.77%) that used TXA intraoperatively. Ten patients (12.65%) received anticoagulation postoperatively, 5 of whom received TXA intraoperatively. Of the 33 patients who received TXA, 30 patients remained on estrogen therapy. There was no statistically significant difference in VTE rates in patients who received TXA (n=33, 41.77%) and those who did not (n=46, 58.23%). Bleeding events, Caprini scores, estimated blood loss, and operative time were also not found to be significantly different between the 2 cohorts. The authors found no significant increase in VTE in facial feminization patients undergoing estrogen supplementation when intraoperative TXA was utilized. This is the first known report investigating the safety of TXA in this higher risk patient population.

Non-pharmacological treatment of reduced quality of life in premature ovarian insufficiency.

Premature ovarian insufficiency (POI) is the spontaneous or induced loss of ovarian function in women under the age of 40. POI increases the risk of reduced quality of life. Hormone replacement therapy may be beneficial in POI, but some women have contraindications. Recent studies indicate that exercise, yoga, meditation, acupuncture, and mindfulness may improve quality of life in women with POI. Phyto-oestrogens are not recommended in the treatment of POI since the physiological level of oestrogen cannot be achieved, and phyto-oestrogens should be avoided in women with present or previous breast cancer.

Treatment of polycystic ovary syndrome and its associated psychiatric symptoms with the Mongolian medicine Nuangong Qiwei Pill and macelignan.

ETHNOPHARMACOLOGICAL RELEVANCE: The Mongolian medicine Nuangong Qiwei Pill (NGQW) is a folk prescription with a long history of use by the Mongolian people. NGQW comprises seven Mongolian medicines, which have the effects of regulating and nourishing blood, warming the uterus, dispelling cold and relieving pain. For a long time, it has been used as a good remedy for gynecological diseases, with remarkable curative effects, favored by the majority of patients and recommended by doctors. Polycystic ovary syndrome (PCOS) is a common gynecological endocrine disorder that can lead to menstrual disorders or infertility. In the gynecological classification of Mongolian medicine, polycystic ovary syndrome has not been distinguished in detail, and the mechanism of NGQW in the treatment of polycystic ovary syndrome has not been scientifically studied and standardized. AIM OF THE STUDY: The aim of this study was to clarify the mechanism of action of NGQW and macelignan in the treatment of PCOS and to provide a reference for the clinical application of these drugs. MATERIALS AND METHODS: The effect of intragastric administration of NGQW and macelignan on PCOS model mice was observed. The mental status of mice was examined behaviorally, and serum hormone levels and oxidative stress parameters were measured by ELISA. Giemsa staining was used to detect the reproductive cycle, and HE staining was used to observe the ovarian status. Immunofluorescence staining was performed to observe the proliferation and apoptosis of ovarian granulosa cells. qRT‒PCR was conducted to measure the expression of IL-6, BAX, BCL-2, and estrogen synthesis-related genes in ovarian tissue and particle cells. RESULTS: In the dehydroepiandrosterone (DHEA)-induced PCOS model mice, both NGQW and macelignan improved the estrous cycle; increased the estradiol (E2) content; lowered testosterone (T), progesterone (P) and luteinizing hormone (LH) levels; reduced the number of polycystic follicles; promoted granulosa cell proliferation; reduced granulosa cell apoptosis; and alleviated depression and anxiety. In addition, Nuangong Qiwei Pill and macelignan reduced the mRNA levels of the ovarian inflammatory factor IL-6; improved the disordered levels of the antioxidant indicators GSH, MDA, and SOD; and activated the TGF-ß3 signaling pathway to increase the transcription of Cyp19a1, which increases estrogen secretion. CONCLUSION: NGQW and macelignan can treat PCOS through the TGF-ß3/Smad/Cyp19a1 signaling pathway to regulate the secretion ability of ovarian granulosa cells. Our research justifies the traditional use of NGQW to treat PCOS and enriches the scope of action of macelignan.

Biochanin-A attenuates DHEA-induced polycystic ovary syndrome via upregulation of GDF9 and BMP15 signaling in vivo.

AIMS: Phytoestrogens can act as natural estrogens owing to their structural similarity to human estrogens. Biochanin-A (BCA) is a well-studied phytoestrogen with a wide variety of pharmacological activities, whereas not reported in the most frequently encountered endocrinopathy called polycystic ovary syndrome (PCOS) in women. PURPOSE: This study aimed to investigate the therapeutic effect of BCA on dehydroepiandrosterone (DHEA) induced PCOS in mice. MAIN METHODS: Thirty-six female C57BL6/J mice were divided into six groups: sesame oil, DHEA-induced PCOS, DHEA + BCA (10 mg/kg/day), DHEA + BCA (20 mg/kg/day), DHEA + BCA (40 mg/kg/day), and metformin (50 mg/kg/day). KEY FINDINGS: The results showed a decrease in obesity, elevated lipid parameters, restoration of hormonal imbalances (testosterone, progesterone, estradiol, adiponectin, insulin, luteinizing hormone, and follicle-stimulating hormone), estrus irregular cyclicity, and pathological changes in the ovary, fat pad, and liver. SIGNIFICANCE: In conclusion, BCA supplementation inhibited the over secretion of inflammatory cytokines (TNF-α, IL-6, and IL-1ß) and upregulated TGFß superfamily markers such as GDF9, BMP15, TGFßR1, and BMPR2 in the ovarian milieu of PCOS mice. Furthermore, BCA reversed insulin resistance by increasing circulating adiponectin levels through a negative correlation with insulin levels. Our results indicate that BCA attenuated DHEA-induced PCOS ovarian derangements, which could be mediated by the TGFß superfamily signaling pathway via GDF9 and BMP15 and associated receptors as first evidenced in this study.

A review on phytoestrogens: Current status and future direction.

Phytoestrogens are plant secondary metabolite that is structurally and functionally similar to mammalian estrogens, which have been shown to have various health benefits in humans. Isoflavones, coumestans, and lignans are the three major bioactive classes of phytoestrogens. It has a complicated mechanism of action involving an interaction with the nuclear estrogen receptor isoforms ERα and ERß, with estrogen agonist and estrogen antagonist effects. Depending on their concentration and bioavailability in various plant sources, phytoestrogens can act as estrogen agonist or antagonists. Menopausal vasomotor symptoms, breast cancer, cardiovascular disease, prostate cancer, menopausal symptoms, and osteoporosis/bone health have all been studied using phytoestrogens as an additional standard hormone supplemental remedy. The botanical sources, techniques of identification, classification, side effects, clinical implications, pharmacological and therapeutic effects of their proposed mode of action, safety issues, and future directions for phytoestrogens have all been highlighted in this review.

Advances in the Management of Menopausal Symptoms, Fertility Preservation, and Bone Health for Women With Breast Cancer on Endocrine Therapy.

In patients with hormone receptor-positive early-stage breast cancer, adjuvant endocrine treatment administered for up to 5-10 years after diagnosis significantly reduces the risk of recurrence and death. However, this benefit comes with the cost of short- and long-term side effects that may negatively affect patients' quality of life (QoL) and treatment adherence. Among them, the prolonged estrogen suppression associated with the use of adjuvant endocrine therapy in both premenopausal and postmenopausal women can induce life-altering menopausal symptoms, including sexual dysfunction. Moreover, a decrease in bone mineral density and an increased risk of fractures should be carefully considered and prevented whenever indicated. For young women diagnosed with hormone receptor-positive breast cancer with unfulfilled childbearing plans, several challenges should be addressed to manage their fertility and pregnancy-related concerns. Proper counseling and proactive management of these issues are critical components of survivorship and should be pursued from diagnosis through the breast cancer care continuum. This study aims to provide an updated overview of the available approaches for improving the QoL of patients with breast cancer receiving estrogen deprivation therapy, focusing on advances in the management of menopausal symptoms, including sexual dysfunction, fertility preservation, and bone health.

Evidence-based review of nonantibiotic urinary tract infection prevention strategies for women: a patient-centered approach.

PURPOSE OF REVIEW: There is a growing interest in nonantibiotic prevention strategies for recurrent urinary tract infections (rUTIs). Our objective is to provide a focused, pragmatic review of the latest evidence. RECENT FINDINGS: Vaginal estrogen is well tolerated and effective for preventing rUTI in postmenopausal women. Cranberry supplements at sufficient doses are effective in preventing uncomplicated rUTI. Methenamine, d -mannose, and increased hydration all have evidence to support their use, although the evidence is of somewhat variable quality. SUMMARY: There is sufficient evidence to recommend vaginal estrogen and cranberry as first-line rUTI prevention strategies, particularly in postmenopausal women. Prevention strategies can be used in series or in tandem, based on patient preference and tolerance for side effects, to create effective nonantibiotic rUTI prevention strategies.

Psoralen prevents the inactivation of estradiol and treats osteoporosis via covalently targeting HSD17B2.

ETHNOPHARMACOLOGICAL RELEVANCE: Psoralea corylifolia L. seeds (P. corylifolia), popularly known as Buguzhi in traditional Chinese medicine, are often used to treat osteoporosis in China. Psoralen (Pso) is the key anti-osteoporosis constituent in P. corylifolia, however, its targets and mechanism of action are still unclear. AIM OF THE STUDY: The purpose of this study was to explore the interaction between Pso and 17-ß hydroxysteroid dehydrogenase type 2 (HSD17B2), an estrogen synthesis-related protein that inhibits the inactivation of estradiol (E2) to treat osteoporosis. MATERIALS AND METHODS: Tissue distribution of Pso was analyzed by in-gel imaging after oral administration of an alkynyl-modified Pso probe (aPso) in mice. The target of Pso in the liver was identified and analyzed using chemical proteomics. Co-localization and cellular thermal shift assays (CETSA) were used to verify the key action targets. To detect the key pharmacophore of Pso, the interaction of Pso and its structural analogs with HSD17B2 was investigated by CETSA, HSD17B2 activity assay, and in-gel imaging determination. Target competitive test, virtual docking, mutated HSD17B2 activity, and CETSA assay were used to identify the binding site of Pso with HSD17B2. A mouse model of osteoporosis was established by ovariectomies, and the efficacy of Pso in vivo was confirmed by micro-CT, H&E staining, HSD17B2 activity, and bone-related biochemical assays. RESULTS: Pso regulated estrogen metabolism by targeting HSD17B2 in the liver, with the α, ß-unsaturated ester in Pso being the key pharmacophore. Pso significantly suppressed HSD17B2 activity by irreversibly binding to Lys236 of HSD17B2 and preventing NAD+ from entering the binding pocket. In vivo studies in ovariectomized mice revealed that Pso could inhibit HSD17B2 activity, prevent the inactivation of E2, increase levels of endogenous estrogen, improve bone metabolism-related indices, and play a role in anti-osteoporosis. CONCLUSIONS: Pso covalently binds to Lys236 of HSD17B2 in hepatocytes to prevent the inactivation of E2, thereby aiding in the treatment of osteoporosis.

Estrógeno potenciado en el tratamiento homeopático del dolor pélvico asociado a endometriosis: un estudio aleatorizado, doble ciego, controlado con placebo, de 24 semanas / Potentiated estrogen in the homeopathic treatment of pelvic pain associated with endometriosis: a 24-week randomized, double-blind, placebo-controlled study

Evaluar la eficacia y seguridad del estrógeno potenciado en comparación con el placebo en el tratamiento homeopático del dolor pélvico asociado a endometriosis (EAPP, por sus siglas en inglés). Diseño del estudio: El presente fue un estudio clínico aleatorizado, doble ciego, controlado con placebo, de 24 semanas, el cual incluyó a 50 mujeres de entre 18 y 45 años de edad con diagnóstico de endometriosis infiltrante profunda con base en ultrasonido transvaginal o imágenes de resonancia magnética después de preparación intestinal, así como puntaje ≥ 5 en una escala visual analógica (VAS: rango de 0 a 10 puntos) para el dolor pélvico asociado con la endometriosis. Se administró estrógeno potenciado (12cH, 18cH y 24cH) o placebo dos veces al día por vía oral. La medida principal de resultado fue el cambio en la severidad de los puntajes parcial y global de EAPP (VAS) de la línea basal a la semana 24, determinada como la diferencia en el puntaje medio de cinco modalidades de dolor pélvico crónico (dismenorrea, dispareunia profunda, dolor pélvico no cíclico, dolor intestinal cíclico y/o dolor urinario cíclico). Las medidas secundarias de resultado fueron la diferencia media de puntaje para la calidad de vida evaluada con el Cuestionario de Salud SF-36, los síntomas de depresión en el Inventario de la Depresión de Beck (BDI) y los síntomas de ansiedad en el Inventario de Ansiedad de Beck (BAI). Resultados: El puntaje global de EAPP (VAS: rango de 0 a 50 puntos) se redujo en 12.82 (p < 0.001) en el grupo tratado con estrógeno potenciado de la línea basal a la semana 24. El grupo que utilizó estrógeno potenciado también presentó una reducción en el puntaje parcial (VAS: rango de 0 a 10 puntos) en tres modalidades de EAPP: dismenorrea (3.28; p < 0.001), dolor pélvico no cíclico (2.71; p = 0.009) y dolor intestinal cíclico (3.40; p < 0.001). El grupo de placebo no mostró cambio significativo alguno en los puntajes global o parcial de EAPP. Además, el grupo de estrógeno potenciado mostró un mejoramiento significativo en tres de ocho ámbitos de SF-36 (dolor de cuerpo, vitalidad y salud mental) y síntomas de depresión (BDI). El grupo de placebo no mostró un mejoramiento significativo a este respecto. Estos resultados demuestran la superioridad del estrógeno potenciado sobre el placebo. Se asociaron pocos eventos adversos con el estrógeno potenciado. Conclusiones: El estrógeno potenciado (12cH, 18cH y 24cH) en dosis de 3 gotas dos veces al día durante 24 semanas fue significativamente más efectivo que el placebo para reducir el dolor pélvico asociado con la endometriosis.

To evaluate the efficacy and safety of potentized estrogen compared to placebo in homeopathic treatment of endometriosis-associated pelvic pain (EAPP). Study design: The present was a 24-week, randomized, doubleblind, placebocontrolled trial that included 50 women aged 18-45 years old with diagnosis of deeply infiltrating endometriosis based on magnetic resonance imaging or transvaginal ultrasound after bowel preparation, and score ≥ 5 on a visual analogue scale (VAS: range 0 to 10 points) for endometriosis-associated pelvic pain. Potentized estrogen (12cH, 18cH and 24cH) or placebo was administered twice daily per oral route. The primary outcome measure was change in the severity of EAPP global and partial scores (VAS) from baseline to week 24, determined as the difference in the mean score of five modalities of chronic pelvic pain (dysmenorrhea, deep dyspareunia, non-cyclic pelvic pain, cyclic bowel pain and/or cyclic urinary pain). The secondary outcome measures were mean score difference for quality of life assessed with SF-36 Health Survey Questionnaire, depression symptoms on Beck Depression Inventory (BDI), and anxiety symptoms on Beck Anxiety Inventory (BAI). Results: The EAPP global score (VAS: range 0 to 50 points) decreased by 12.82 (p < 0.001) in the group treated with potentized estrogen from baseline to week 24. Group that used potentized estrogen also exhibited partial score (VAS: range 0 to 10 points) reduction in three EAPP modalities: dysmenorrhea (3.28; p < 0.001), non-cyclic pelvic pain (2.71; p = 0.009), and cyclic bowel pain (3.40; p < 0.001). Placebo group did not show any significant changes in EAPP global or partial scores. In addition, the potentized estrogen group showed significant improvement in three of eight SF-36 domains (bodily pain, vitality and mental health) and depression symptoms (BDI). Placebo group showed no significant improvement in this regard. These results demonstrate superiority of potentized estrogen over placebo. Few adverse events were associated with potentized estrogen. Conclusions: Potentized estrogen (12cH, 18cH and 24cH) at a dose of 3 drops twice daily for 24 weeks was significantly more effective than placebo for reducing endometriosis-associated pelvic pain.

Targeting Estrogen Signaling in the Radiation-induced Neurodegeneration: A Possible Role of Phytoestrogens.

Radiation for medical use is a well-established therapeutic method with an excellent prognosis rate for various cancer treatments. Unfortunately, a high dose of radiation therapy comes with its own share of side effects, causing radiation-induced non-specific cellular toxicity; consequently, a large percentage of treated patients suffer from chronic effects during the treatment and even after the post-treatment. Accumulating data evidenced that radiation exposure to the brain can alter the diverse cognitive-related signaling and cause progressive neurodegeneration in patients because of elevated oxidative stress, neuroinflammation, and loss of neurogenesis. Epidemiological studies suggested the beneficial effect of hormonal therapy using estrogen in slowing down the progression of various neuropathologies. Despite its primary function as a sex hormone, estrogen is also renowned for its neuroprotective activity and could manage radiation-induced side effects as it regulates many hallmarks of neurodegenerations. Thus, treatment with estrogen and estrogen-like molecules or modulators, including phytoestrogens, might be a potential approach capable of neuroprotection in radiation-induced brain degeneration. This review summarized the molecular mechanisms of radiation effects and estrogen signaling in the manifestation of neurodegeneration and highlighted the current evidence on the phytoestrogen mediated protective effect against radiationinduced brain injury. This existing knowledge points towards a new area to expand to identify the possible alternative therapy that can be taken with radiation therapy as adjuvants to improve patients' quality of life with compromised cognitive function.

Effect of Benson's relaxation therapy alone or combined with aerobic exercise on cortisol, sleeping quality, estrogen, and severity of dyspeptic symptoms in perimenopausal women with functional dyspepsia.

OBJECTIVE: Besides repeated stress exposure, a sedentary lifestyle and low estrogen levels are risk factors for the development of functional dyspepsia (FD). The aim of this study was to find out the effect of adding aerobic exercise (5 sessions per week) to the daily application of a 40-minute Benson's relaxation therapy (BRT) (diaphragmatic breathing and progressive muscle relaxation applied for 20 minutes in the morning and evening) on Glasgow dyspepsia severity score (GDSS), cortisol, visual analogue scale (VAS) (for abdominal symptoms), estradiol (one of the endogenous estrogens), Pittsburgh sleep quality index (PSQI), and 42-item depression, anxiety, and stress scales (DASS-42) in 60 perimenopausal women with FD. PATIENTS AND METHODS: Women who consumed a daily dose of pantoprazole (40 mg tablet administered as a proton pump inhibitor drug) were randomly assigned to an 8-week study group (this group received aerobic exercise plus BRT, N=30) or an 8-week control group (this group received BRT only, N=30). RESULTS: Significant improvements were reported in all measured variables within women groups (except estradiol of the control group). Compared to the control group, the reported within-group significant improvements in GDSS, cortisol, VAS, PSQI, and DASS-42 were higher in the study group. CONCLUSIONS: Significant improvements in GDSS, cortisol, VAS, PSQI, and DASS-42 could be achieved after adding adjunctive therapies - aerobic exercise and BRT - to the medications of FD in perimenopausal women. Compared to BRT alone, physical exercise plus BRT significantly increases the levels of estradiol in perimenopausal women with FD.

OBJECTIVES: Hysteroscopic adhesiolysis (HA) remains the mainstay on treatment for intrauterine adhesions (IUA). The fertility outcome of patients with moderate and severe intrauterine adhesions after HA is still far from satisfactory. Estrogen combined with progesterone is the most common treatment; however, they do not help in improving the fertility rate to the maximum because of the limitations. This retrospective, non-randomized controlled study will assess the effects of traditional Chinese medicine Yangmo decoction after HA in restoration of the endometrium and improvement of the fertility rate. METHODS: A total of 427 patients, who met the inclusion criteria, aged between 20 and 45 years and diagnosed with moderate or severe IUA underwent HA at the Third Xiangya Hospital from January to August 2021, were enrolled for this study. Participants were assigned into 2 groups: A Yangmo decoction group (n=213, patients were given Yangmo decoction consisting of Ginseng flower, Sanchi flower, Daidai flower, Snow lotus, Licorice and so on after HA), and an estrogen and progesterone group (n=214, patients were given estrogen and progesterone after HA). The following basic information was collected retrospectively for both groups, including age, parity, history of abortion, menstrual status, and times of hysteroscopic interventions. American Fertility Society (AFS) score was used by a senior surgeon and the density of opening of endometrial glands was evaluated during HA. The parameters were obtained from three-dimensional transvaginal ultrasound (3D-TVUS) preoperatively and postoperatively, to evaluate the efficacy of Yangmo decoction, estrogen, and progesterone. All patients were followed up on telephone to determine the fertility rate until 6 months from the last HA. RESULTS: Based on the basic information collected preoperatively, there were no significant differences between the groups (all P>0.05). Postoperatively, patients in the Yangmo decoction group had a better surgical success rate with a more significant AFS reduction (P<0.001), better density of opening of endometrial glands in the uterine cavity (P<0.000 1) after HA, and a better fertility rate (40.4%) in the time of 6 months after the last HA than those of the estrogen and progesterone group. CONCLUSIONS: Yangmo decoction has better therapeutic efficacy in the treatment of intrauterine adhesion after HA than the combined effect of estrogen and progesterone. Yangmo decoction helps restore the endometrium and improve the fertility rate, therefore, it can be adopted as a routine practice for IUA patients who have fertility requirements.
