Cisplatin-induced acute kidney injury (CP-AKI) is a common complication in cancer patients. Although ferroptosis is believed to contribute to the progression of CP-AKI, its mechanisms remain incompletely understood. In this study, after initially processed individual omics datasets, we integrated multi-omics data to construct a ferroptosis network in the kidney, resulting in the identification of the key driver TACSTD2. In vitro and in vivo results showed that TACSTD2 was notably upregulated in cisplatin-treated kidneys and BUMPT cells...

Why compound bioidentical hormones? Are there no similar commercial products? What is unique about the options compounding pharmacists offer compared with what is out in the marketplace? These are questions that physicians and other practitioners are asking, and it is very important that we have intelligent, well-thought answers when we respond. Times have changed, and the challenges we face today in marketing our compounded therapies are not the same as those of twenty years ago. Premarin is no longer at the top of the heap, and there are topical, commercial products that contain bioidentical estradiol, and capsules that contain the same progesterone that we use...

OBJECTIVES: To evaluate the efficacy and safety of physical energy use in managing GSM symptoms. SEARCH STRATEGY: Five databases were searched from inception to December 2022. Language restrictions were not imposed. SELECTION CRITERIA: We included all Cochrane and non-Cochrane systematic reviews with or without meta-analyses that described postmenopausal women with symptoms of GSM treated with physical energy...

OBJECTIVE: This study aimed to determine long-term cardiometabolic effects of hormone therapies initiated within 3 years of onset of menopause after a 14-year follow-up study of participants of the Kronos Early Estrogen Prevention Study (KEEPS). METHODS: KEEPS was a multisite clinical trial that recruited recently menopausal women with good cardiovascular health for randomization to oral conjugated equine estrogens (Premarin, 0.45 mg/d) or transdermal 17β-estradiol (Climara, 50 μg/d) both with micronized progesterone (Prometrium, 200 mg/d) for 12 d/mo, or placebo pills and patch for 4 years...

This work aimed to explore the effect of nerve magnetic stimulation based on superparamagnetic Fe3O4 nanoparticle (NP) on bone metabolism during the perimenopausal period. First, the multifunctional water-soluble polymer PTMP-PMAA was utilized as the ligand. PTMP-MAA@ Fe3O4 NP with high magnetization was prepared by the co-precipitation method, and NPX diffraction pattern analysis and in vitro stability analysis were implemented. Then, NPs were co-cultured with 293T cells, and the cytotoxicity was detected by the CCK-8 method...

Spinal cord injury (SCI) occurs when the spinal cord is damaged from either a traumatic event or disease. SCI is characterised by multiple injury phases that affect the transmission of sensory and motor signals and lead to temporary or long-term functional deficits. There are few treatments for SCI. Estrogens and estrogenic compounds, however, may effectively mitigate the effects of SCI and therefore represent viable treatment options. This review systematically examines the pre-clinical literature on estrogen and estrogenic compound neuroprotection after SCI...

UNLABELLED: BACKGROUND AND OBJECTIVE: Postmenopausal women often require estrogen supplementation to improve menopausal and postmenopausal vasomotor symptoms and maintain hormonal balance. Conjugated equine estrogens extracted from the urine of pregnant mares are commonly used to provide this estrogen replacement therapy. The complex composition of this mixture of animal sulfated metabolites makes its bioanalysis challenging such that its detailed pharmacokinetics has not been fully characterized...

AIM: In a randomized, multicenter, open, controlled trial, we compared the effects of Honglilai Vaginal Cream and Premarin Vaginal Cream in different age subgroups and menopausal year subgroups (trial registration numbers: 02003L00493). METHODS: Postmenopausal women with Genitourinary Syndrome of Menopause (GSM) were divided into Honglilai group ( n  = 319) and Premarin group ( n  = 116), while subgroups were divided according to their different characteristics of age and menopausal years...

Osteoporosis, the most common bone disease, is associated with compromised bone strength and increased risk of fracture. Previous studies have shown that oxidative stress contributes to the progression of osteoporosis. Specifically, for postmenopausal osteoporosis, the reduction in estrogen levels leads to increased oxidative stress in bone remodeling. Tocotrienol, a member of vitamin E that exhibits antioxidant activities, has shown potential as an agent for the treatment of osteoporosis. Most studies on the osteoprotective effects of tocotrienols had used the oral form of tocotrienols, despite their low bioavailability due the lack of transfer proteins and high metabolism in the liver...

OBJECTIVE: To investigate the therapeutic effect of Er-Xian decoction on the autoimmune premature ovarian failure (POF) in mice, and its regulatory mechanisms. METHODS: Female BALB mice were treated with a single intraperitoneal injection of zona pellucida 3 (ZP3). One week later, mice received low (5 g/kg), moderate (10 g/kg) and high (20g/kg) doses of EXD by gastrogavage once daily for 90 d. Premarin (0.03 mg/kg) served as the positive control group. Serum levels of estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH) were measured by enzyme-linked immunosorbent assay, lymphocyte subtypes were analyzed, and follicular structure differences were observed by hematoxylin and eosin staining...

Introduction: Sexual dysfunction is a complex problem in postmenopausal women with a prevalence rate of 68%-86%. This study aimed to evaluate the effect of a fractional CO2 laser or vaginal cream on the improvement of sexual function in menopausal women. Methods: This is a two-group clinical trial study. Postmenopausal women with the inclusion criterion were enrolled and randomly divided into 2 groups of intervention (n=25) and control group (n=25). In the intervention group, CO2 laser therapy was performed every month for three months, and in the control group, Premarin vaginal cream was applied (0...

BACKGROUND: Previous work has shown that the vaginal microbiome decreases in Lactobacillus predominance and becomes more diverse after menopause. It has also been shown that estrogen therapy restores Lactobacillus dominance in the vagina and that topical estrogen is associated with overactive bladder symptom improvement. We now know that the bladder contains a unique microbiome and that increased bladder microbiome diversity is associated with overactive bladder. However, there is no understanding of how quickly each pelvic floor microbiome responds to estrogen or if those changes are associated with symptom improvement...

The presented work summarizes the results of studies underlining the crucial role of estrogen receptor (ER) signaling in both innate and adaptive immune responses as well as in tissue repairing processes during respiratory virus infection. Experimental studies justify that among respiratory virus infected mice, a weaker ER signaling leads to increased morbidity and mortality in both males and females. In animal experiments, estrogen treatment silences the inflammatory reactions and decreases virus titers leading to improved survival rate; it seems to be an ideal prevention and therapy against COVID-19...

BACKGROUND AND AIM: Both virgin coconut oil (VCO) and tocotrienol-rich fraction (TRF) are rich in antioxidants and may protect the bone against bone loss induced by ovariectomy and high-fat diet. The study aimed to determine the protective effects of combined therapy of VCO and TRF on osteoporosis in ovariectomized (OVX) rat fed with high-fat diet. MATERIALS AND METHODS: Thirty-six female Sprague-Dawley rats were divided into six groups: Sham-operated (SHAM), OVX control, OVX and given Premarin at 64...

The public assumes that some foods, such as milk and ground beef from cattle receiving steroidal implants, are associated with estrogenic hormones, while other foods are presumed "safe" or nonestrogenic. Here, we investigate these assumptions by assessing the relative estrogenic activity of a serving size of four foods: skim milk (8 oz), rice (48 g dry wt) in cooking bag, ground beef patties from steers raised with or without hormone implantation (quarter lb each, 114 g), and tofu burgers (isocaloric to beef burger, 198 g), using an in vitro assay (E-Screen)...

Conjugated equine estrogens (CEEs), whose brand name is Premarin, are widely used as a hormone-replacement therapy (HRT) drug to manage postmenopausal symptoms in women. Extracted from pregnant mare urine, CEEs are composed of nearly a dozen estrogens existing in an inactive sulfated form. To determine whether the hepatic steroid sulfatase (STS) is a key contributor to the efficacy of CEEs in HRT, we performed estrogen-responsive element (ERE) reporter gene assay, real-time PCR, and UPLC-MS/MS to assess the STS-dependent and inflammation-responsive estrogenic activity of CEEs in HepG2 cells and human primary hepatocytes...

BACKGROUND: Hormonal fluctuations may trigger the onset of bipolar disorder. We designed a longitudinal follow-up study to evaluate the association between hysterectomies and bipolar disorder risk. METHODS: We conducted a large retrospective cohort study using Taiwan's National Health Insurance Research Database. A total of 4,337 women aged 30 to 50 years who underwent the hysterectomy during 2000-2013 were selected and 17,348 patients without hysterectomy were selected for comparison (1:4 match)...

OBJECTIVES: The efficacy and safety of 25-μg 17β-estradiol vaginal tablets (Vagifem) were assessed and compared with 1.25-mg conjugated equine estrogen vaginal cream (Premarin Vaginal Cream) for the relief of menopausal-derived atrophic vaginitis, resulting from estrogen deficiency. DESIGN: In a multicenter, open-label, randomized, parallel-group study, 159 menopausal women were treated for 24 weeks with either vaginal tablets or vaginal cream. Efficacy was evaluated by relief of vaginal symptoms and concentrations of serum estradiol and follicle-stimulating hormone...

Prior to 2002, hormone replacement therapy (HRT) was considered to be an important component of postmenopausal healthcare. This was based on a plethora of basic, epidemiological and clinical studies demonstrating the health benefits of supplementation with human sex steroids. However, adverse findings from the Women's Health Initiative (WHI) studies that examined the 2 major forms of HRT in use in the US at that time - Premarin (conjugated equine estrogens; CEE) and Prempro (CEE + medroxyprogesterone acetate; MPA), cast a shadow over the use of any form of HRT...
