Puberty in girls with Prader-Willi syndrome: cohort evaluation and clinical recommendations in a Latin American tertiary center.

Introduction: Prader-Willi syndrome (PWS) is a genetic disorder characterized by hypothalamic-pituitary deficiencies including hypogonadism. In girls with PWS, hypogonadism can present early in childhood, leading to genital hypoplasia, delayed puberty, incomplete pubertal development, and infertility. In contrast, girls can present with premature activation of the adrenal axis leading to early pubarche and advanced bone age. We aim to evaluate the progression of puberty and adrenarche signals in girls with PWS. Methodology: A longitudinal retrospective cohort study included girls with PWS followed at a Pediatric Endocrinology Outpatient Clinic in a Tertiary University Hospital in Sao Paulo, Brazil from 2002 to 2022. Data collected via chart review included clinical information on birth history, breast and pubic hair Tanner stages, presence of genital hypoplasia, age at menarche, regularity of menstrual cycles, body mass index (BMI) z-score, final height, age of initiation of estrogen replacement and growth hormone replacement, as well as results for PWS genetic subtype; biochemical investigation (LH, FSH, estradiol, DHEA-S); radiographic bone age and pelvic ultrasound. Results: A total of 69 girls were included in the study and the mean age of puberty onset was 10.2 years in those who started puberty after the age of 8 years. Breast Tanner stage IV was reached by 29.1% girls at a mean age of 14.9 years. Spontaneous menarche was present in 13.8% and only one patient had regular menstrual cycles. Early adrenarche was seen in 40.4% of cases. Conclusion: Our study demonstrated in a large sample that girls with PWS often present with delayed onset of puberty despite frequent premature adrenarche. Based on our results, we suggest an estrogen replacement protocol for girls with PWS to be started at the chronological age or bone age of 12-13 years, taking into consideration the uterus size. Further prospective studies are needed.

Reduced protein carbonylation on hormone therapy is associated with improved fibrinolysis in postmenopausal women: the impact of PAI-1 and TAFI activity.

Hormone therapy (HT) has been reported to reduce protein carbonylation (PC) in postmenopausal women, in whom fibrinolysis is impaired. We investigated whether PC affects fibrinolysis and if HT modulates this effect. We enrolled 150 women aged 55.5 ± 4.7 years in a randomized interventional open-label study, including 50 on standard oral HT, 50 on ultra-low-dose HT, and 50 controls. PC, along with global fibrinolysis (clot lysis time, CLT), fibrinolysis proteins, and prothrombotic markers were determined at baseline and at 24 weeks. Patients with the baseline top quartile PC (> 2.07 nM/mg protein) had 10.3% longer CLT, higher activity (but not antigen) of TAFI (+ 19.9%) and PAI-1 (+ 68.1%) compared to the remainder. No differences were observed in thrombin generation, factor VIII, plasminogen or α2-antiplasmin. On-treatment PC decreased by 16.4% (p < 0.0001), without differences related to the type of HT, compared to baseline and by 30% compared to controls, in whom PC and fibrinolysis markers remained unchanged. Patients with PC > 2.07 nM/mg had shortened CLT during HT compared to baseline, along with lower PAI-1 (-69%) and TAFI (-26%) activity. In this subgroup CLT was 5.8% shorter compared to controls with the highest PC. In postmenopausal women with increased PC, HT was accompanied by PC reduction and faster clot lysis together with decreased PAI-1 and TAFI activity.

Usage of the levonorgestrel releasing intrauterine system in perimenopause.

Levonorgestrel releasing intrauterine system have excellent contraceptive efficacy with simultaneous lowering of menstruation's blood loss. It could be used for therapy of endometrial hyperplasia in perimenopause. In position of gestagen part of the hormone replacement therapy it has high control of endometrial proliferation. It is conjoined with the zero increasing of risk of thromboembolic disease in combination with transdermal oestrogen's application.

Factors affecting prognosis and need for anti-vascular endothelial growth factor injections in wet age-related macular degeneration.

PURPOSE: To understand factors affecting visual prognosis and the number of intravitreal antivascular endothelial growth factor (anti-VEGF) injections needed to stabilize wet age-related macular degeneration (AMD). METHODS: In this retrospective cohort, 119 treatment-naïve wet AMD patients were followed for two years. In patients with bilateral disease, the eye with worse best-corrected visual acuity (BCVA) or that received more intravitreal injections was recruited as the study eye. In all visits, BCVA was recorded, ophthalmological examination was performed including macular optical coherence tomography imaging. Twenty health status/lifestyle questions were asked to the patients via phone as potential risk factors. All patients received 3 loading doses of intravitreal bevacizumab injections and received repeat injections of aflibercept or ranibizumab when the eye had a new, active neovascular lesion. RESULTS: Patients who took regular micronutrition had similar visual outcome and injection numbers compared to the ones who did not. Patients with bilateral disease needed less intravitreal injections compared to unilateral AMD patients (p = 0.016) and women on hormone replacement therapy (HRT) required less injections compared to the women who were not (p = 0.024). Female patients had a mean gain of 2.7 letters while male patients lost 3.8 letters (p = 0.038). Wet AMD started at an earlier age in smokers (p = 0.002). Patients with a better education level presented earlier with better BCVA (p = 0.037). CONCLUSION: HRT and anti-VEGF injections to the fellow eye improved the prognosis of wet AMD, while male patients had slightly worse prognosis. Estrogen's protective effects and potential contribution in wet AMD needs further attention. Retrospectively registered: 2020/0622.

Different endometrial preparation protocols on first frozen-thawed embryo transfer outcomes after hysteroscopic polypectomy: A retrospective cohort study.

OBJECTIVE: To evaluate the optimal endometrial preparation protocol for frozen-thawed embryo transfer (FET) following hysteroscopic polypectomy. METHODS: This was a retrospective clinical cohort study involving 464 patients who underwent their first FET after polyp resection between January 2021 and July 2023. The cohorts were categorized into three groups: the natural cycle (NC) group (n = 139), the ovarian induction (OI) group (n = 117), and the hormone replacement therapy (HRT) group (n = 208). RESULTS: In the initial unadjusted analysis, both NC and OI cycles exhibited similar pregnancy rates but were associated with significantly higher implantation rate (56.5%, 57.1% vs 42.0%, P < 0.001), clinical pregnancy rate (73.4%, 74.4% vs 57.2%, P = 0.001), and ongoing pregnancy rate (OPR; 67.6%, 63.2% vs 51.0%, P = 0.005) compared to the HRT group. Additionally, the three groups demonstrated comparable abortion rate (7.8%, 14.9% vs 10.9%, P = 0.299). After adjusting for potential confounders in the multiple logistic regression model, the HRT protocol resulted in a 54% significantly lower OPR compared to the NC protocol (adjusted odds ratio [aOR] = 0.46, 95% confidence interval [CI]: 0.28-0.77; P = 0.003). Meanwhile, the OPR difference between the OI protocol and the NC protocol remained insignificant (OI vs NC: aOR = 0.62, 95% CI: 0.35-1.12; P = 0.112). CONCLUSION: The ovulatory-FET scheme (NC and OI) following hysteroscopic polyp resection displayed promising clinical outcomes compared with HRT-FET scheme. The regimen without exogenous estrogen administration should be prioritized for endometrial preparation protocol after polypectomy.

Factors affecting shared decision-making concerning menopausal hormone therapy.

Menopausal hormone therapy (MHT) is an effective treatment for menopause-related symptoms. Menopause management guidelines recommend a personalized approach to menopause care, including MHT use. Decision-making around menopause care is a complex, iterative process influenced by multiple factors framed by perspectives from both women and healthcare providers (HCPs). This narrative review aims to summarize evidence around factors affecting decision-making regarding menopause-related care. For HCPs, the provision of individualized risk estimates is challenging in practice given the number of potential benefits and risks to consider, and the complexity of the data available, especially within time-limited consultations. Women seeking menopause care have the difficult task of making sense of the benefit versus risk profiles to make choices in line with their decisional needs influenced by sociocultural/economic, educational, demographic, and personal characteristics. The press, social media, and influential celebrities also impact the perception of menopause and decision-making around it. Understanding these factors can lead to improved participation in shared decision-making, satisfaction with the decision and decision-making process, adherence to treatment, reduced decisional regret, efficient use of resources, and ultimately long-term satisfaction with care.

Rare secondary hypertension caused by compound heterozygous CYP17A1 mutations: a case report.

Background: 17α-Hydroxylase deficiency, a rare form of congenital adrenal hyperplasia, presents diagnostic and treatment challenges because of the limited number of cases reported. Case summary: This report discusses the case of a 17-year-old Chinese girl who suffered from unexplained dizziness, headaches, and high blood pressure. She had amenorrhoea during puberty and had been diagnosed with ovarian delay. Initially, she was diagnosed with hypertension and received three antihypertensive medications. However, her blood pressure remained poorly controlled. Gene sequencing revealed 17α-hydroxylase deficiency caused by compound heterozygous mutations in CYP17A1. One of the mutation sites, potentially novel, has not been reported previously. Subsequently, dexamethasone therapy was initiated, her blood pressure was controlled, and the symptoms disappeared. During the 1-year follow-up, her blood pressure remained normal, and the symptoms did not recur. Discussion: 17α-Hydroxylase deficiency is a rare cause of secondary hypertension. Despite the low prevalence, it should not be overlooked in younger patients.

Individualized luteal phase support in frozen-thawed embryo transfer after intramuscular progesterone administration might rectify live birth rate.

Background: The serum P concentrations are suggested to have an impact on pregnancy outcome. However there is no consensus about the optimal progesterone cut-off during the luteal phase. Few studies evaluated the effectiveness of a "rescue protocol" for low serum P concentrations and most of these studies used vaginal progesterone administration. There is paucity of data on the effectiveness of rescue protocol using intramuscular progesterone (IM-P) in frozen-thawed embryo transfer (FET). Methods: This study is a retrospective cohort study included 637 single or double blastocyst FETs with artificially prepared endometrium receiving 100 mg IM progesterone (P) after incremental estrogen treatment. Serum P concentrations were evaluated using blood samples obtained 117-119 hours after the first IM-P administration and 21 ± 2 hours after the last IM-P administration. Patients with serum P concentrations <20.6 ng/ml on the ET day were administrated 400 mg vaginal progesterone for rescue. Results: Demographic and cycle characteristics were similar between patients receiving rescue vaginal P (embryo transfer (ET)-day P concentration < 20.6 ng/ml) and patients who did not need rescue vaginal P (ET-day P concentration ≥ 20.6 ng/ml). Clinical pregnancy, miscarriage, and live birth rates were similar between two groups: 52.9%(45/85) vs 59.6%(326/552), p=0.287; 11.1%(5/45) vs 14.1%(46/326), p=0.583; and 47.1%(40/85) vs 50.7%(280/552), p=0.526, respectively. Logistic regression analysis revealed that the female age (p = 0.008, OR=0.942, 95% CI = 0.902-0.984) and embryo quality (ref: good quality for moderate: p=0.02, OR=0.469, 95% CI =0.269-0.760; for poor: p=0.013, OR= 0.269, 95% CI = 0.092-0.757) were independent variables for live birth. Following rescue protocol implementation, ET-day P concentration was not a significant predictor of live birth. Conclusions: Rescue vaginal P administration for low ET day serum P concentrations following IM-P yields comparable live birth rates.

Does the use of double hormone replacement therapy for trauma patient organ donors improve organ recovery for transplant.

BACKGROUND: With an ongoing demand for transplantable organs, optimization of donor management protocols, specifically in trauma populations, is important for obtaining a high yield of viable organs per patient. Endocrine management of brain-dead potential organ donors (BPODs) is controversial, leading to heterogeneous clinical management approaches. Previous studies have shown that when levothyroxine was combined with other treatments, including steroids, vasopressin, and insulin, BPODs had better organ recovery and survival outcomes were increased for transplant recipients. AIM: To determine if levothyroxine use in combination with steroids in BPODs increased the number of organs donated in trauma patients. METHODS: A retrospective review of adult BPODs from a single level 1 trauma center over ten years was performed. Exclusion criteria included patients who were not solid organ donors, patients who were not declared brain dead (donation after circulatory death), and patients who did not receive steroids in their hospital course. Levothyroxine and steroid administration, the number of organs donated, the types of organs donated, and demographic information were recorded. Univariate analyses were performed with P < 0.05 considered to be statistically significant. RESULTS: A total of 88 patients met inclusion criteria, 69 (78%) of whom received levothyroxine and steroids (ST/LT group) vs 19 (22%) receiving steroids without levothyroxine (ST group). No differences were observed between the groups for gender, race, pertinent injury factors, age, or other hormone therapies used (P > 0.05). In the ST/LT group, 68.1% (n = 47) donated a high yield (3-5) of organ types per donor compared to 42.1% (n = 8) in the ST group (P = 0.038). There was no difference in the total number of organ types donated between the groups (P = 0.068). CONCLUSION: This study suggests that combining levothyroxine and steroid administration increases high-yield organ donation per donor in BPODs in the trauma patient population. Limitations to this study include the retrospective design and the relatively small number of organ donors who met inclusion criteria. This study is unique in that it mitigates steroid administration as a confounding variable and focuses specifically on the adjunctive use of levothyroxine.

Effect of testosterone therapy on breast tissue composition and mammographic breast density in trans masculine individuals.

BACKGROUND: The effect of gender-affirming testosterone therapy (TT) on breast cancer risk is unclear. This study investigated the association between TT and breast tissue composition and breast tissue density in trans masculine individuals (TMIs). METHODS: Of the 444 TMIs who underwent chest-contouring surgeries between 2013 and 2019, breast tissue composition was assessed in 425 TMIs by the pathologists (categories of lobular atrophy and stromal composition) and using our automated deep-learning algorithm (% epithelium, % fibrous stroma, and % fat). Forty-two out of 444 TMIs had mammography prior to surgery and their breast tissue density was read by a radiologist. Mammography digital files, available for 25/42 TMIs, were analyzed using the LIBRA software to obtain percent density, absolute dense area, and absolute non-dense area. Linear regression was used to describe the associations between duration of TT use and breast tissue composition or breast tissue density measures, while adjusting for potential confounders. Analyses stratified by body mass index were also conducted. RESULTS: Longer duration of TT use was associated with increasing degrees of lobular atrophy (p < 0.001) but not fibrous content (p = 0.82). Every 6 months of TT was associated with decreasing amounts of epithelium (exp(ß) = 0.97, 95% CI 0.95,0.98, adj p = 0.005) and fibrous stroma (exp(ß) = 0.99, 95% CI 0.98,1.00, adj p = 0.05), but not fat (exp(ß) = 1.01, 95%CI 0.98,1.05, adj p = 0.39). The effect of TT on breast epithelium was attenuated in overweight/obese TMIs (exp(ß) = 0.98, 95% CI 0.95,1.01, adj p = 0.14). When comparing TT users versus non-users, TT users had 28% less epithelium (exp(ß) = 0.72, 95% CI 0.58,0.90, adj p = 0.003). There was no association between TT and radiologist's breast density assessment (p = 0.58) or LIBRA measurements (p > 0.05). CONCLUSIONS: TT decreases breast epithelium, but this effect is attenuated in overweight/obese TMIs. TT has the potential to affect the breast cancer risk of TMIs. Further studies are warranted to elucidate the effect of TT on breast density and breast cancer risk.

Advanced drug delivery technologies for postmenopausal effects.

Postmenopause is the 12-month absence of menstrual periods, characterized by decreased estrogen and progesterone levels, leading to physical and psychological alterations such as hot flashes, mood swings, sleep disruptions, and skin changes. Present postmenopausal treatments include hormone replacement therapy, non-hormonal drugs, lifestyle modifications, vaginal estrogen therapy, bone health treatments, and alternative therapies. Advanced drug delivery systems (ADDSs) are essential in managing postmenopausal effects (PMEs), offering targeted and controlled delivery to alleviate symptoms and improve overall health. This review emphasizes such ADDSs for addressing PMEs. Emerging trends such as artificial ovaries are also reviewed. Additionally, the prospects of technologies such as additive manufacturing (3D and 4D printing) and artificial intelligence in further tailoring therapeutic strategies against PMEs are provided.

Use of an estradiol transdermal spray in women with menopausal symptoms: a non-interventional study.

OBJECTIVE: This study aimed to investigate the effectiveness, tolerability and application of estradiol metered-dose transdermal spray (EMDTS) in postmenopausal women during real-world use. METHODS: This was a prospective, non-interventional, multicenter, observational phase IV cohort study. The Menopause Rating Scale II (MRS II) was used to assess symptoms and clinical response. Safety was assessed by the occurrence of adverse events and adverse drug reactions (ADRs). RESULTS: A total of 451 postmenopausal women were enrolled at 52 gynecological practices across Germany; 383 patients were evaluated for effectiveness and 430 patients for safety. Mean age was 54.3 ± 7.4 years. In total, 228 patients (59.5%) received EMDTS monotherapy and 155 patients (40.5%) received EMDTS plus progestogens. Significant improvements (p < 0.0001) from baseline in symptom severity were recorded for all 11 items of the MRS II at 3, 6 and 12 months of treatment. At 12 months, 81.4% of patients reported improvement in hot flushes/sweating. At final visit, 73% of patients and 77% of physicians were 'satisfied/very pleased' with EMDTS. Most common ADRs were headache (n = 6), nausea (n = 4), dizziness (n = 4) and pruritus (n = 3). CONCLUSIONS: EMDTS is an effective, well tolerated and easily applied hormone replacement therapy for women experiencing postmenopausal symptoms.

Breaking barriers: How transwomen meet their healthcare needs.

BACKGROUND:  Transgender women - individuals assigned male at birth but who identify as female - are disproportionately affected by, among others, human immunodeficiency virus (HIV), other sexually transmitted diseases (STIs) and mental health issues. Studies show that transgender women often encounter discrimination and stigma when seeking healthcare from health facilities. AIM:  This study assessed the healthcare needs of transgender women, their experiences of the mainstream healthcare system and alternative strategies for navigating the healthcare system. SETTING:  The study was carried out in the City of Ekurhuleni Metropolitan Council in South Africa's Gauteng province. METHODS:  A case study design was followed. Participants were purposively selected and included 10 transgender women aged 26-50. Individual semi-structured interviews were conducted over 2 months. RESULTS:  Participants expressed a need for hormone replacement therapy, HIV treatment and prevention and treatment for STIs. Experiences of participants within the healthcare system were predominantly negative, with instances of discrimination, stigma and privacy violations being commonplace. Alternative strategies to meet their healthcare needs included the use of self-medication, consulting traditional healers and utilising non-governmental organisations. CONCLUSION:  There is an urgent need for equitable and inclusive health management of transgender women in South Africa.Contribution: This study provided a first look in a South African context into how and to what extent transwomen employ alternative healthcare strategies such as self-medication and utilising non-governmental organisations when faced with mainstream healthcare access barriers. The use of traditional doctors was identified as a novel, alternative strategy used by transwomen to access healthcare and treatment.

[Analysis of Reproductive Tract Microecological Changes During the Frozen-Thawed Embryo Transfer Cycle and Clinical Pregnancy Outcomes]. / æ¿€ç´ æ›¿ä»£å†»èƒšç§»æ¤å‘¨æœŸç”Ÿæ®–é“å¾®ç”Ÿæ€å˜åŒ–ä¸Žå¦Šå¨ ç»“å±€åˆ†æž.

Objective: This study aims to analyze the relationship between reproductive tract microecological changes, metabolic differences, and pregnancy outcomes at different time points in the frozen-thawed embryo transfer cycle while patients are undergoing hormone replacement therapy, which will be a breakthrough point for improving outcomes. Methods: A total of 20 women undergoing frozen-thawed single blastocyst transfer for the first time at the Reproductive Medicine Center of Fujian Maternal and Child Health Hospital between July 2022 and January 2023 were recruited for this study. Their vaginal and cervical secretions were collected for 16S rRNA sequencing and non-targeted metabolomics analysis on days 2-5 of menstruation, day 7 after estrogen replacement therapy started, the day when progesterone was added, and the day of transplantation. The subjects were divided into different groups according to their clinical pregnancy status and the sequencing results were analyzed using bioinformatics methods. Results: 1) The alpha-diversity index of the vaginal and cervical microbiota was higher on days 2-5 of menstruation (P<0.01), but did not differ significantly on day 7 after oral estrogen replacement therapy started, the day of progesterone administration, and the day of transplantation (P≥0.1). 2) Both the pregnant group and the non-pregnant group showed a variety of microorganisms and metabolites with significant differences in the lower reproductive tract at different time points. 3) Microbial analysis at different time points showed that there were significant differences in vaginal flora, including Peptoniphilus, Enterocloster, Finegoldia, Klebsiella, Anaerobutyricum, Agathobaculum, Sporanaerobacter, Bilophila, Prevotella, and Anaerococcus in the pregnant group (P<0.05). 4) Metabolite analysis at different time points showed that there were significant differences in 3-hydroxybenzoic acid, linatine, (R)-amphetamine, hydroxychloroquine, and L-altarate in the vaginal secretions of the pregnant group (P<0.05), and that there were significant differences in isocitric acid, quassin, citrinin, and 12(R)-HETE in the cervical secretions (P<0.05). 5) Metabolite analysis at different time points showed that, in the non-pregnant group, there were significant differences in linatine, decanoyl-L-carnitine, aspartame, sphingosine, and hydroxychloroquine in the vaginal secretions (P<0.05), and the isocitric acid, quassin, ctrinin, and 12(R)-HETE in the cervical secretions (P<0.05). 6) Combined microbiome and metabolomics analysis showed that certain metabolites were significantly associated with microbial communities, especially Klebsiella. Conclusions: Significant differences in the microbiota genera and metabolites at different time points were found during the frozen-embryo transfer cycle of hormone replacement therapy, which may be used as potential biomarkers to predict pregnancy outcomes of embryo transfer.

Hormone replacement therapy and myocardial infarction and stroke in postmenopausal Korean women.

OBJECTIVE: This study aimed to investigate the association of hormone replacement therapy (HRT) use, type, duration and age of commencement with myocardial infarction (MI) and stroke in postmenopausal Korean women. METHODS: This nested case-control study used data from the National Health Insurance Service database to analyze 2017 data from women aged ≥50 years and diagnosed with natural menopause between 2004 and 2007. Among 356,160 eligible women, 36,446 used HRT for ≥1 year and 319,714 did not (controls). These two groups were matched 1:1 for statistical analysis. Type and duration were categorized into three categories. RESULTS: Women who started estrogen-progestogen therapy (EPT) or estrogen therapy (ET) in their 50s, or EPT or tibolone in their ≥60s exhibited a lower stroke risk than controls. MI risk was lower among women who used tibolone - regardless of duration - or EPT or ET for 1-3 years than among controls. Stroke risk was lower with tibolone use for ≥5 years or with EPT or ET use for 1-3 years or ≥5 years than non-users. CONCLUSION: Our study may support the beneficial effect of HRT by showing that Korean postmenopausal women who used HRT at a relatively younger and healthier age had a relative benefit for MI and stroke.

Rare Case of Growth Hormone Insensitivity Syndrome Correlated With Hypothyroidism: A Case Report.

Growth hormone insensitivity syndrome (GHIS) is a rare genetic disorder characterized by short stature due to the body's inability to effectively utilize growth hormone (GH). This case report describes a patient with concurrent hypothyroidism and GHIS. This patient is an 11-year-old female presented with short stature; general examination suggested a prominent forehead and a depressed nasal bridge. Laboratory evaluations revealed elevated thyroid-stimulating hormone (TSH) levels alongside low levels of triiodothyronine (T3) and thyroxine (T4), indicating hypothyroidism. Additionally, elevated GH levels and significantly reduced insulin-like growth factor 1 (IGF-1) levels confirmed the diagnosis of GHIS. The patient was managed with thyroid hormone replacement therapy and recombinant GH. This dual therapeutic approach will lead to improvements in both thyroid function and growth parameters. This case underscores the importance of recognizing and addressing coexisting endocrine disorders in patients with GHIS to optimize their growth and developmental outcomes. Early diagnosis and a comprehensive treatment strategy are essential for managing such complex cases effectively.

Comparing Cancer Risks and Mortality between Phytopharmaceuticals and Estrogen-Progestogen Medications for Menopausal Women: A Population-Based Cohort Study.

We evaluated the long-term risks of overall cancer and all-cause mortality associated with five types of phytopharmaceuticals and the most commonly used estrogen-progestogen medications for the treatment of postmenopausal syndrome in women. Using data from Taiwan's National Health Insurance Research Database (NHIRD) from 1 January 2000 to 31 December 2018, we conducted a 1:2 matched cohort study with 12,087 eligible patients. We compared phytopharmaceuticals -only users (n = 4029, phytopharmaceuticals group) with HRT-only users (n = 8058, HRT group) with a washout period of ≥6 months. The phytopharmaceuticals group had significantly lower risks of overall cancer and all-cause mortality than the HRT group (adjusted hazard ratio [95% confidence interval]: 0.60 [0.40-0.9] and 0.40 [0.16-0.99], respectively) after over 180 days of use. Bupleurum and Peony Formula were associated with lower risks of overall cancer and all-cause mortality (aHR: 0.57 [0.36-0.92] and 0.33 [0.11-1.05], respectively). In conclusion, phytopharmaceuticals may serve as an alternative therapy to HRT for alleviating menopausal symptoms and reducing health risks, leading to more favorable long-term health outcomes. Further randomized control trials are necessary to validate the findings of this study.

Sex reconfigured: DIY hormone therapy and vernacular endocrinology in transfeminine communities in China.

Faced with a restrictive institutional medical landscape, trans people in China turn to DIY (Do-It-Yourself) hormone therapy. While existing health literature has studied the risks and impacts of informal hormone therapy, little is known about the practical strategies and the embedded meaning-making processes around hormone-taking on the ground. Building on digital and in-person participant observation conducted in two cities in China and semi-structured interviews with eight transfeminine individuals between 2021 and 2022, this article examines the embodied practices and community knowledge of tinkering with hormones. Specifically, I examine the ways that conventional biomedical notions of efficacy and risk are both enrolled and contested to understand bodily becoming in the community space. Closely engaging with biomedical structures, ideas, and knowledge, trans people challenge and reformulate dominant notions of efficacy, risk, and toxicity. A form of DIY hormone literacy is taking shape in the community, informed by the hands-on engagement with medicine, an affinity with pharmaceuticals, and people's temporal narratives of transition. Throughout these processes, DIY practitioners multiply the materials and imaginations of medicine. They reshape the narrowly-defined biomedical model of sex and enable an alternative onto-epistemology of hormonal sex-gender that is amenable to modification and constantly in flux. Drawing from medical anthropology, science and technology studies (STS), and feminist, queer, and trans studies, this article contributes to the conversation on the politics and poetics of sex-gender and embodied knowledge production in the community space.

A local audit evaluating bone health in patients with functional hypothalamic amenorrhoea secondary to an eating disorder and a review of the application of hormone therapy in this clinical setting.

It is widely known that estrogen has a fundamental role to play in skeletal homeostasis. In the most reductionist sense, the action of estrogen can be surmised as anti-resorptive. Estrogen prevents the break-down of bone. It therefore follows that estrogen deficiency states, such as the menopause and functional hypothalamic amenorrhoea (FHA), are often characterised by increased bone remodelling and disrupted skeletal homeostasis. FHA is the cessation of menstruation secondary to abnormal signalling between the hypothalamus and pituitary gland due to deficient pulsatile secretion of Gonadotrophin Releasing Hormone (GnRH). Functional hypothalamic amenorrhoea is frequently a consequence of women suffering with eating disorders. The development of FHA secondary to eating disorders is an evolutionary adaptive response to chronic metabolic energy deficiency. Fundamentally, preservation of life is biologically prioritised over dispensable physiological process such as reproduction. Consequently, the hypothalamic-pituitary-ovarian (HPO) axis fails, which disrupts menstrual function and ovulation, culminating in a state of estrogen deficiency. One of the most important and long-lasting deleterious consequences of FHA is disrupted skeletal homeostasis and bone loss. Estrogen replacement, most commonly in the form of combined hormone replacement therapy (HRT) or the combined oral contraceptive pill (COCP), is advised for women with an early menopause to prevent bone loss. Arguably, estrogen replacement should also be utilised in the context of FHA. However, the optimum estrogen regime for women with FHA remains under-researched and so management is not evidence-based.
