Abstract
OBJECTIVE To evaluate the effectiveness and possible mechanism of acupuncture treatment for negative emotion in patients with polycystic ovary syndrome (PCOS). METHODS A total of 40 PCOS patients were randomly divided into an observation group and a control group, 20 cases in each one. Both groups received lifestyle interventions (exercise and diet guidance) on the 5th day of menstruation. On the basis of above treatment, the patients in the observation group received acupuncture at Guanyuan (CV 4), Zhongwan (CV 12), Guilai (ST 29), Futu (ST 32), Liangqiu (ST 34), Sanyinjiao (SP 6), Zusanli (ST 36), Hegu (LI 4), Shenmen (HT 7), Baihui (GV 20) as the main acupoints, and connected the electroacupuncture (continuous wave, 2 Hz, 30 min), once every other day, 3 times a week. The treatment for 1 month was as one course and 4 courses were required totally in both groups. Before and after treatment, the body mass index (BMI), ferriman-gallway (F-G) score, self-rating anxiety scale (SAS) score, self-rating depression scale (SDS) score, PCOS health-related quality of life questionnaire (PCOSQ) score were observed, meanwhile, serum sex hormone, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E2), progestin (P), prolactin (PRL), testosterone (T), sex hormone-binding globulin (SHBG) and free androgen index (FAI) levels, and serumβ-endorphin levels were detected. RESULTS Compared with before treatment, the BMI, F-G score, SAS score, SDS score and serum FAI level were decreased and the PCOSQ score and the levels of serum SHBG andβ-endorphin were increased in the observation group after treatment (all P<0.05). Compared with before treatment, the SDS score was decreased in the control group after treatment (P<0.05). Compared with the control group, the F-G score, SDS score, SAS score, and serum FAI level were lower, and the PCOSQ score and serumβ-endorphin level were higher in the observation group after treatment (all P<0.05). CONCLUSION Applying acupuncture to the treatment of patients with PCOS can effectively relieve anxiety and depression, and the mechanism may be related to the regulation on the levels of serumβ-endorphin and androgen.

Abstract
Observational research suggests that micronutrients may be protective for sarcopenia, a key health issue during ageing, potentially via effects on hormone synthesis and metabolism. We aimed to carry out a systematic review of RCTs investigating effects of increasing dietary or supplemental micronutrient intake on sex hormones and IGF-1 in individuals aged 45 years or older. We searched MEDLINE, EMBASE and Cochrane databases for RCTs reporting the effects of different micronutrients (vitamins A, C, D, or E; carotenoids; iron; copper; zinc; magnesium; selenium; and potassium) on sex hormones or IGF-1. Of the 26 RCTs identified, nine examined effects of vitamin D, nine of multi-nutrients, four of carotenoids, two of selenium, one of zinc, and one of vitamin E. For IGF-1 increasing vitamin D (MD: -0.53 nmol/L, 95% CI: -1.58, 0.52), multi-nutrients (MD: 0.60 nmol/L, 95% CI -1.12 to 2.33) and carotenoids (MD -1.32 nmol/L; 95% CI -2.76 to 0.11) had no significant effect on circulating concentrations. No significant effects on sex hormones of other micronutrients were found, but data were very limited. All trials had significant methodological limitations making effects of micronutrient supplementation on sex hormones unclear. Further high quality RCTs with physiological doses of micronutrients in people with low baseline intakes or circulating concentrations, using robust methodology, are required to assess effects of supplementation adequately.

Journal of the World federation of orthodontists. 2020;(1):9-12
Abstract
BACKGROUND Functional appliances has been used for treatment of skeletal Class II malocclusion for a long time; however, the real skeletal effects, mandibular growth particularly, remain insufficient. Several auxiliary approaches have been attempted with the hope of enhancing treatment effects. In this review, we summarize and discuss the use of additional nutrition and hormones to assist the functional appliance treatment on patients with skeletal Class II malocclusion. METHODS Relevant articles were identified by electronic research in MEDLINE Ovid using keywords such as "nutrition," "hormone," "functional appliance," "orthodontics," "maxillofacial development," and "maxillofacial abnormalities." References of related articles were assessed for relevant studies to identify additional published references. RESULTS The literature search yielded 239 studies. According to the current literature, use of additional nutrition and hormones, including growth hormones, sex hormones, insulin, and insulin-like growth factor I, seem to improve the effects of functional appliance treatment on patients with skeletal Class II malocclusion. CONCLUSIONS The current evidence indicates that additional nutrition or hormones might improve the treatment effects on mandibular hypoplasia compared with the functional appliance alone, which is a promising approach and calls for further studies.

Abstract
CONTEXT Survival rates after severe injury are improving, but complication rates and outcomes are variable. OBJECTIVE This cohort study addressed the lack of longitudinal data on the steroid response to major trauma and during recovery. DESIGN We undertook a prospective, observational cohort study from time of injury to 6 months postinjury at a major UK trauma centre and a military rehabilitation unit, studying patients within 24 hours of major trauma (estimated New Injury Severity Score (NISS) > 15). MAIN OUTCOME MEASURES We measured adrenal and gonadal steroids in serum and 24-hour urine by mass spectrometry, assessed muscle loss by ultrasound and nitrogen excretion, and recorded clinical outcomes (ventilator days, length of hospital stay, opioid use, incidence of organ dysfunction, and sepsis); results were analyzed by generalized mixed-effect linear models. FINDINGS We screened 996 multiple injured adults, approached 106, and recruited 95 eligible patients; 87 survived. We analyzed all male survivors <50 years not treated with steroids (N = 60; median age 27 [interquartile range 24-31] years; median NISS 34 [29-44]). Urinary nitrogen excretion and muscle loss peaked after 1 and 6 weeks, respectively. Serum testosterone, dehydroepiandrosterone, and dehydroepiandrosterone sulfate decreased immediately after trauma and took 2, 4, and more than 6 months, respectively, to recover; opioid treatment delayed dehydroepiandrosterone recovery in a dose-dependent fashion. Androgens and precursors correlated with SOFA score and probability of sepsis. CONCLUSION The catabolic response to severe injury was accompanied by acute and sustained androgen suppression. Whether androgen supplementation improves health outcomes after major trauma requires further investigation.

Human Follicle in vitro Culture Including Activation, Growth, and Maturation: A Review of Research Progress.
Yang, Q, Zhu, L, Jin, L
Frontiers in endocrinology. 2020;:548
Abstract
Fertility preservation has received unprecedented attention nowadays. In addition to cryopreservation and re-implantation of embryos, oocytes, and ovarian tissue pieces, in vitro culture system for follicles/oocytes has been considered as an alternative strategy for fertility preservation. Since the metabolic dynamics and required nutrients are not entirely the same in different stages of follicular development, optimization of each culture step is needed. In this paper, literature regarding culture conditions in three steps were analyzed. Known additives in activation stage included 740Y-P, bpV(HOpic), follicle stimulating hormone (FSH), human serum albumin (HSA), ITS, growth differentiation factor 9 (GDF9), bone morphogenetic protein 15 (BMP15), and cyclic adenosine monophosphate (cAMP), with different degrees of activation promotion and potential detrimental effect on DNA integrity. For isolated follicles growth stage, actin A, FSH, basic fibroblast growth factor (bFGF), estradiol were proved to improve development or proliferation. As for maturation, addition of growth hormone, melatonin, C-type natriuretic peptide (CNP), GDF9, cilostamide, or forskolin helped to regulate maturation rate or improve oocyte quality. Based on previous sequential culture system for human follicles, optimization is needed to achieve higher maturation rate and better oocyte quality, pursuant to current review, which demonstrated the effects of various additives on different stages.

Abstract
Conditions of impaired adrenal function and tissue destruction, such as in Addison's disease, and treatment resistance of adrenocortical carcinoma (ACC) necessitate improved understanding of the pathophysiology of adrenal cell death. Due to relevant oxidative processes in the adrenal cortex, our study investigated the role of ferroptosis, an iron-dependent cell death mechanism and found high adrenocortical expression of glutathione peroxidase 4 (GPX4) and long-chain-fatty-acid CoA ligase 4 (ACSL4) genes, key factors in the initiation of ferroptosis. By applying MALDI mass spectrometry imaging to normal and neoplastic adrenocortical tissue, we detected high abundance of arachidonic and adrenic acid, two long chain polyunsaturated fatty acids which undergo peroxidation during ferroptosis. In three available adrenal cortex cell models (H295R, CU-ACC1 and CU-ACC-2) a high susceptibility to GPX4 inhibition with RSL3 was documented with EC50 values of 5.7 × 10-8, 8.1 × 10-7 and 2.1 × 10-8 M, respectively, while all non-steroidogenic cells were significantly less sensitive. Complete block of GPX4 activity by RSL3 led to ferroptosis which was completely reversed in adrenal cortex cells by inhibition of steroidogenesis with ketoconazole but not by blocking the final step of cortisol synthesis with metyrapone. Mitotane, the only approved drug for ACC did not induce ferroptosis, despite strong induction of lipid peroxidation in ACC cells. Together, this report is the first to demonstrate extraordinary sensitivity of adrenal cortex cells to ferroptosis dependent on their active steroid synthetic pathways. Mitotane does not induce this form of cell death in ACC cells.

Abstract
BACKGROUND Obesity disproportionately affects more women than men. The loss of ovarian function during the menopause transition coincides with weight gain, increases in abdominal adiposity, and impaired metabolic health. Racial differences in obesity prevalence that results from the menopause transition are not well understood. OBJECTIVE The purpose of the study was to assess longitudinal changes in body composition and cardiometabolic risk among black and white women during the menopausal transition. STUDY DESIGN In a secondary analysis of a prospective, observational cohort study (the Healthy Transitions study), 161 women ≥43 years old with a body mass index of 20-40 kg/m2 and who had not yet transitioned through menopause were enrolled at Pennington Biomedical Research Center. Women were seen annually for body composition by dual-energy X-ray absorptiometry, for abdominal adipose tissue distribution by computed tomography, for sex steroid hormones, and for cardiometabolic risk factors that include fasting glucose, insulin, and lipids. Surrogate measures of insulin sensitivity were also calculated. RESULTS Ninety-four women (25 black, 69 white) transitioned through menopause and were included within the analyses. At menopause onset, black women weighed more (77.8±3.0 vs 70.8±1.8 kg) and had a higher systolic (125±16 vs 118±14 mm Hg) and diastolic (80±8 vs 74±7 mm Hg) blood pressure compared with white women (all P≤.05). No other differences in body composition, sex steroid hormones, or cardiometabolic risk factors were observed at menopause onset. Before menopause, white women gained significant weight (3 kg), total body adiposity (6% percent body fat, 9% fat mass, 12% trunk fat mass) and abdominal adipose tissue (19% subcutaneous fat, 15% visceral fat, 19% total adipose tissue), which coincided with significant decreases in estradiol, sex hormone-binding globulin, and estrone sulfate and increases in follicle-stimulating hormone, total cholesterol, and low-density lipoprotein cholesterol. Conversely, black women had more abdominal adipose tissue before menopause, which was maintained across the menopause transition. Black women also had significant decreases in estrone sulfate and total testosterone and increases in follicle-stimulating hormone before menopause. In the postmenopausal years, abdominal subcutaneous adipose tissue, total adipose tissue, follicle-stimulating hormone, total cholesterol, and low-density and high-density lipoprotein cholesterol increased only in white women. CONCLUSION White women gained more abdominal adiposity during the menopause transition compared with black women, which, in part, may be due to differences in the pattern of sex steroid hormone changes between women of different racial backgrounds. The gains in abdominal adiposity in white women were observed in tandem with increased cardiometabolic risk factors. Future studies should consider comprehensive lifestyle approaches to target these increased gains in abdominal adiposity (ie, nutrition and physical activity coaching), while taking into account the potential interactions of race, body adiposity, sex steroid hormones, and their influence on cardiometabolic risk.

Steroidogenic Acute Regulatory Protein: Structure, Functioning, and Regulation.
Tugaeva, KV, Sluchanko, NN
Biochemistry. Biokhimiia. 2019;(Suppl 1):S233-S253
Abstract
Steroidogenesis takes place mainly in adrenal and gonadal cells that produce a variety of structurally similar hormones regulating numerous body functions. The rate-limiting stage of steroidogenesis is cholesterol delivery to the inner mitochondrial membrane, where it is converted by cytochrome P450scc into pregnenolone, a common precursor of all steroid hormones. The major role of supplying mitochondria with cholesterol belongs to steroidogenic acute regulatory protein (STARD1). STARD1, which is synthesized de novo as a precursor containing mitochondrial localization sequence and sterol-binding domain, significantly accelerates cholesterol transport and production of pregnenolone. Despite a tremendous interest in STARD1 fueled by its involvement in hereditary diseases and extensive efforts of numerous laboratories worldwide, many aspects of STARD1 structure, functioning, and regulation remain obscure and debatable. This review presents current concepts on the structure of STARD1 and other lipid transfer proteins, the role of STARD1 in steroidogenesis, and the mechanism of its functioning, as well as identifies the most controversial and least studied questions related to the activity of this protein.

Stress-induced disturbances along the gut microbiota-immune-brain axis and implications for mental health: Does sex matter?
Audet, MC
Frontiers in neuroendocrinology. 2019;:100772
Abstract
Women are roughly twice as likely as men to suffer from stress-related disorders, especially major depression and generalized anxiety. Accumulating evidence suggest that microbes inhabiting the gastrointestinal tract (the gut microbiota) interact with the host brain and may play a key role in the pathogenesis of mental illnesses. Here, the possibility that sexually dimorphic alterations along the gut microbiota-immune-brain axis could play a role in promoting this female bias of mood and anxiety disorders will be discussed. This review will also analyze the idea that gut microbes and sex hormones influence each other, and that this reciprocal crosstalk may come to modulate inflammatory players along the gut microbiota-immune-brain axis and influence behavior in a sex-dependent way.

Abstract
BACKGROUND AND AIMS Polycystic Ovarian Syndrome is a common reproductive, endocrine, and metabolic disease in women. Pomegranate juice, known as a rich source of phytochemicals with high antioxidant activity, enriched with probiotic may improve PCOS. METHODS AND RESULTS A randomized, controlled, triple-blinded, parallel trial study was performed in PCOS patients (n = 92). Three treatment groups (23 patients each) received 2 L of synbiotic pomegranate juice (SPJ), pomegranate juice (PJ), and synbiotic beverage (SB) weekly. The control group (23 patients) received 2 L of placebo beverage weekly. Primary outcome was any change in insulin resistance and secondary outcomes were fasting blood sugar (FBS), insulin sensitivity, testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH), body mass index (BMI), waist and hip circumference, from baseline to the end of the trial. At the end of the study, 86 patients were analyzed. There was significant change in insulin resistance in the SPJ and SB groups. Insulin sensitivity increased significantly in the SPJ and SB groups. Insulin also changed significantly in the SPJ and SB groups. BMI, weight and waist circumference decreased significantly in the SPJ and SB groups. Testosterone level also decreased significantly in the SPJ and SB groups. There was no significant change in FPG, LH and FSH in any of the groups. CONCLUSION SPJ in the form of a new beverage can improve insulin resistance, insulin, testosterone level, BMI, weight and waist circumference in PCOS. This trial was registered in Iranian Registry of Clinical Trials, with number: 25272.
