Multigenerational effects of combined exposure of triphenyltin and micro/nanoplastics on marine medaka (Oryzias melastigma): From molecular levels to behavioral response

In natural environments, micro/nanoplastics (MNP) inevitably coexist with various pollutants, making it essential to examine their combined toxicity and intergenerational effects on marine organisms. This study investigated the combined toxicity and intergenerational effects of exposure to triphenyltin (T), microplastics (M), nanoplastics (N), a combination of microplastics and triphenyltin (MT), and a combination of nanoplastics and triphenyltin (NT) on marine medaka. The results showed that all treatments had adverse and intergenerational effects on marine medaka. Regarding oxidative stress and energy metabolism, smaller sized plastic particles caused more significant damage to the organisms. However, MT inflicted greater gonadal system damage than NT, leading to imbalanced sex hormone levels. Additionally, T induced hyperactivity in fish, whereas MNP tended to induce behavioral depression. Notably, large plastic particles in the F0 generation had a more pronounced impact on depressive behaviors compared to smaller particles. These findings suggest that both individual and combined exposures to TPT and MNP can detrimentally affect marine medaka from the molecular to behavioral levels, posing risks to population sustainability. This study provided a robust theoretical foundation and deeper insights into the ecotoxicological impacts and risk assessments of coexisting pollutants.

Estrogen receptors and vascular aging

After years of studying cardiovascular diseases (CVD) in men due to their higher incidence compared to women, attention is now being paid to female CVD and their pathophysiology. Even though premenopausal women have a lower incidence of CVD, this disparity progressively diminishes after menopause, highlighting the key role of sex hormones. Many preclinical and fundamental studies have demonstrated protective effects of estrogens on arterial endothelium, suggesting that hormone therapy could improve cardiovascular health in menopausal women. However, disappointing outcomes from a major clinical trial two decades ago questioned the cardiovascular protection by estrogens with age. In this review, we will summarize the main clinical and experimental studies reporting the effects of estrogens on CVD, with a focus on their impact on endothelial function. Then, we will present abnormalities in the expression and signaling of estrogen receptors (ERs) in the arteries, and the contribution of conventional estrogens to arterial protection during aging. Finally, we will examine how recent advances in the mechanisms of action of ERa could help to optimize hormone therapy for menopause.

Sex, Acute Kidney Injury, and Age: A Prospective Cohort Study

Animal models of kidney disease suggest a protective role for female sex hormones but in humans, some authorities assert that female sex is a risk factor for acute kidney injury (AKI). To better understand the risk of AKI, we studied the strength of association between sex and AKI incidence in hormonally distinct age groups across the life span. Prospective cohort study. All patients hospitalized in the Montefiore Health System between 10/15/2015 and 1/1/2019, excluding those with kidney failure or obstetrics diagnoses. Male versus female sex. Acute kidney injury (AKI) occurring during hospitalization based on KDIGO definitions. Generalized Estimating Equation logistic regression adjusted for comorbidities, socio-demographic factors, and severity of illness. Analyses were stratified into 3 age categories, 6 months to ≤16 years, age >16 years - <55 years, and age ≥55 years. A total of 132,667 individuals were hospitalized a total of 235,629 times. The mean age was 55.2 (SD 23.8) years. The counts (%) of hospitalizations for women were 129,912 (55%). Hospitalization counts (%) among Black and Hispanic patients were 71,834 (30.5%) and 24,199 (10.3%), respectively. AKI occurred in 53,926 (22.9%) hospitalizations. In adjusted models, there was a significant interaction between age and sex (p<0.001). Boys and men had higher risk of AKI across all age groups, an association more pronounced in the age group >16 years to <55 years in which the OR for men was 1.7 (95% CI, 1.6-1.8). This age-based pattern remained consistent across prespecified types of hospitalizations. In a sensitivity analysis, women older than 55 years who received prescriptions for estrogen had lower odds of AKI than those without prescriptions. Residual confounding. The greatest relative risk of AKI for males occurred during ages >16 to <55 years. The lower risk among post-menopausal women receiving supplemental estrogen supports a protective role for female sex hormones.

Pumpkin seed oil lessens the colchicine-induced altered sex male hormone balance, testicular oxidative status, sperm abnormalities, and collagen deposition in male rats via Caspase3/Desmin/PCNA modulation

This study examined the efficiency of pumpkin seed oil (PSO) to rescue the colchicine (CHC)-induced adverse impacts on sperm characteristics, male sex hormones, testicular architecture, oxidative status, DNA content, collagen deposition, and immune expression of desmin and PCNA. Male Sprague Dawley rats were divided into four experimental groups (n = 10 each): control (distilled water), CHC (0.6 mg/kg b.wt), PSO (4 mL/kg b.wt), and CHC + PSO. After 60 days of dosing, CHC significantly reduced sperm motility (19%), sperm concentration (38%), estradiol (52%), testosterone (37%), luteinizing hormone (54%), and follicle-stimulating hormone (29%) compared to the control. Yet, the testicular tissues of CHC-administered rats exhibited elevated abnormal sperms (156%), malondialdehyde (354%), lactate dehydrogenase (73%), Caspase-3 (66%), and 8-hydroxyguanosine (65%) but lower reduced glutathione (74%), catalase (73%), and superoxide dismutase (78%) compared to the control group. Moreover, CHC induced testicular degeneration, distorted seminiferous tubules, apoptotic cells, exfoliated spermatogenic cells, reduced DNA content, decreased PCNA and desmin immune-expression, and increased collagen deposition. PSO effectively reversed the CHC-induced alterations in sperm quality and testicular function and architecture, likely through its antioxidant, antifibrotic, anti-apoptotic, and DNA-protective properties. These results suggest that PSO may be a beneficial intervention for long-term CHC users and may protect against CHC-induced male reproductive toxicity.

Preparation and in vitro/in vivo evaluation of uniform-sized Goserelin-loaded sustained release microspheres

Sustained release microspheres loaded with goserelin are regarded as a promising candidate for treating prostate cancer and other sex hormone diseases. However, their widespread adoption has been hindered by issues such as wide particle size distribution and unstable release characteristics. To address these challenges, we employed a combination of the solid-in-oil-in-water microspheres preparation approach (S/O/W) and innovative premix membrane emulsification technology and deeply investigated the effects of four key parameters on the loaded performance of microspheres and the microscopic mechanisms behind them. With this approach, we successfully produced goserelin-loaded sustained release microspheres of narrow particle size distribution (Span 0.642), remarkable encapsulation efficiency (DL = 4.23 %, EE = 93.98 %), low initial burst release (about 0.50 % within 2 h), and compatibility with small injection needles (23-G, inner diameter 0.33 mm, outer diameter 0.64 mm, maximal force 59 N). In the animal model(administered dose, 2.4 mg·Kg−1), goserelin long-acting sustained release microspheres sustained release for over 32 days, maintaining effective concentrations above 2 ng·mL−1, and effectively reduced serum testosterone concentrations to castration levels (<1.0 ng·mL−1) by day 4, maintaining this inhibition for up to 21 days, exhibiting comparable efficacy to the positive control group. In vivo release kinetics analysis revealed that goserelin-loaded sustained release microspheres exhibited a release pattern dominated by diffusion with corrosion assistance in vivo. In summary, the systematic and comprehensive evaluation of uniform-sized goserelin-loaded sustained release microspheres has highlighted their excellent translational potential, and the study herein may provide new strategies and ideas for the development of microsphere dosage forms.

Regulation of the Organic Anion Transporting Polypeptide 1B3 (OATP1B3) by Sex Hormones.

The mechanisms of regulation of the organic anion transporting polypeptide OATP1B3 by sex hormones were studied using HepG2 cells. Estradiol, progesterone, and testosterone were added to cells at concentrations of 1, 10, 100 μM for 24 h. The relative content of OATP1B3 was evaluated by Western blotting. Estradiol at concentrations of 10 and 100 μM increased the level of OATP1B3 acting through the farnesoid X-receptor, testosterone at concentrations of 1, 10, and 100 μM increased the expression of the transporter protein due to its effect on the liver X-receptor subtype α (LXRα), and progesterone did not affect the expression of OATP1B3.

Involvement of Sex Hormones and Their Receptors in the Pathogenesis of Classic Kaposi's Sarcoma in Xinjiang.

This study aims to examine the expression of androgen receptor (AR) and estrogen receptor (ER) in patients with classic Kaposi's sarcoma (CKS) in Xinjiang, as well as to assess the serum levels of sex hormones in these patients. The objective is to explore potential new directions and targets for diagnosing and treating CKS in Xinjiang. The case group comprised 35 patients diagnosed with CKS who presented at our hospital from 2014 to 2021. The control group consisted of 35 patients with pyogenic granuloma (PG) who visited the hospital during the same period, selected using propensity score matching (PSM). Immunohistochemistry was used to detect AR, human herpesvirus type 8 (HHV-8), and ER in paraffin-embedded tissue samples from patients diagnosed with CKS and PG. Additionally, enzyme-linked immunosorbent assay (ELISA) was used to quantitatively measure serum sex hormone levels in the 35 patients with CKS and 35 patients with PG. AR expression was relatively weak in both the CKS and PG groups, with the PG group exhibiting a slightly stronger expression than the CKS group. Conversely, the expression of ER was significantly higher in the CKS group compared to the PG group (p < 0.05). Additionally, serum testosterone (T) levels were elevated in the CKS group, while serum estradiol (E2) levels were higher in the PG group (p < 0.05). Sex hormones and their receptors are implicated in the pathogenesis of CKS in Xinjiang. The use of ER antagonists may represent a novel avenue for research and treatment of CKS.

The Relationship between Sudden Sensorineural Hearing Loss and Serum Sex Hormone Levels in Perimenopausal Women

Background: The purpose of the study was to explore the relationship between sudden sensorineural hearing loss (SSNHL) and serum sex hormone levels in perimenopausal women, as well as to further investigate the influence of these indicators for SSNHL in perimenopausal women. Methods: A total of 156 patients with SSNHL and 149 healthy individuals during perimenopause who received treatment or underwent physical examination in the Fourth Hospital of Shijiazhuang from August 2023 to December 2023 were selected to participate in this retrospective cohort study. The variances in fundamental patient data were analyzed using the Mann-Whitney U test and Chi-square test. We employed multivariate logistic regression to examine the association between serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), testosterone (T), prolactin (PRL) levels and the occurrence of SSNHL in perimenopausal women. Spearman analysis was used to analyze the correlation between perimenopausal women serum sex hormone levels and SSNH. Results: Compared to the non SSNHL group, the SSNHL group women had lower serum levels of E2 and P ((35.08 ± 12.49) pmoL/L and (0.63 ± 0.24) nmoL/L) vs. ((43.46 ± 10.17) pmoL/L and (0.84 ± 0.13) nmoL/L) (p &lt; 0.05). Multiple logistic regression analysis demonstrated that E2 and P were both at higher risk with the development of SSNHL. Spearman correlation analysis found that E2 and P are negatively correlated with pure tone hearing threshold in perimenopausal women. Conclusions: SSNHL in perimenopausal women may be related to their serum levels of sex hormones.

The impact of chronic stress on the hormonal state of women affected by hostilities and displaced women

During times of war, refugee women often have high levels of chronic stress due to factors such as war, displacement and uncertainty. The study focuses on examining the hormonal responses of female refugees experiencing chronic stress from war and displacement.The objective: to assess the impact of chronic stress caused by war and displacement on the hormonal balance of refugee women.Materials and methods. 60 women were examined, who were divided into groups: the 1st group included women who were affected by hostilities (20 persons), and the 2nd group included displaced women (20 individuals). In these 40 women the hormonal studies were conducted in the conditions of military aggression in Ukraine. The control group (3rd group) included healthy women who were examined in the pre-war period. All examined women were 20–25 years old with an average body weight of 55–60 kg. Concentrations of progesterone, estradiol, follicle-stimulating hormone (FSH) and luteinizing hormone, prolactin in the I and II phases of the menstrual cycle (MC), cortisol in the I phase of the MC were determined in blood serum using the enzyme immunoassay method. An analysis of the results of research on the role of the hypothalamic-pituitary-adrenal system in the regulation of the stress response was carried out.Results. In the examined women, various disorders of MC were observed, such as: menometrorrhagia, hypermenorrhea, acyclic uterine bleeding, oligomenorrhea, and amenorrhea. The most pronounced changes in menstrual function were observed in women who were affected by hostilities. Such significant disorders of MC in women of this group coincided with changes in indicators of gonadotropic hormones of the pituitary gland and sex hormones in the blood.A study of the psycho-emotional state of women who suffered from hostilities established that these women have a significant stressful effect of various risk factors on the body. Changes in the levels of cortisol, prolactin and other hormones were detected.Conclusions. Studies have shown that chronic stress affects the hormonal status of women affected by hostilities and of displaced women, including FSH, estradiol, and prolactin levels.A significant increase in the level of FSH in the follicular phase of the menstrual cycle and an increase in the level of estradiol in the luteal phase were determined, which may indicate a compensatory reaction of the body to stress. A significant increase in the level of prolactin was also found, which can cause disorders of menstrual function and affect the psycho-emotional state.

RELATIONSHIP BETWEEN HYPOGONADISM AND SERUM TESTOSTERONE LEVELS IN CHRONIC LIVER DISEASE

Background: Men with extensive chronic liver disease usually have low levels of testosterone in the serum. This study looked at the relationship between hypogonadism and low serum testosterone levels in patients with chronic liver disease. Methods: This retrospective study was conducted at Central Park Teaching Hospital, Lahore from Jan 2022 to Jan 2024, on patients between 5 to 60 years of age. After approval from ERB and permission from the authorities, records were retrieved. Two hundred records of men with hepatic cirrhosis and verified hypogonadism were divided into alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD), while records of 150 men as control group were include in the study. Patients’ data for ‘Sex Hormone Binding Globulin (SHBG)’ and ‘total testosterone’ were collected and entered into MS Excel file. Using SPSS-22 independent Student’s t-test was applied for statistical analysis. Results: No statistically significant variations were observed (p=0.101) in the means of SHBG across two groups but there was a statistically significant (p&lt;0.05) variation in blood serum testosterone levels between age groups. Conclusion: Hypogonadism and low levels of testosterone are strongly linked to male patients with cirrhotic liver conditions, particularly in those with ALD, while no significant impact of SHBG was found between the two groups. Significant differences were observed between patients with ALD and NAFLD in terms of testosterone levels. Pak J Physiol 2024;20(3):53–5, DOI: https://doi.org/10.69656/pjp.v20i3.1687

Sleep Disturbance in Perimenopausal Women

Female sex hormones are involved in various physiological processes including sleep and the circadian cycle. During menopausal transition, various symptoms caused by hormonal changes can occur. Among various perimenopausal symptoms, sleep disturbance is one of the most common and important health issues. More than 40% of perimenopausal women report sleep problems, which not only lower quality of life but also pose substantial health risks including increased cardiovascular risk. Factors contributing to sleep disturbances during perimenopause include direct changes in sleep due to decline of female sex hormones and indirect changes resulting from perimenopausal symptoms. This article will address the influence of female sex hormones on sleep and circadian rhythm, sleep changes in perimenopausal women and their possible mechanisms, prevalent sleep disorders during perimenopause, and their treatments.

Hormonal status of patients with infertility and post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a mental disorder that occurs after a psychologically or physically traumatic event, and characterized by three main clusters of posttraumatic symptoms, as well as chronic and significant disturbances in emotion regulation, identity, and relationships. PTSD is more common in women, which suggests a role for the regulation of female sex hormones in its development.The objective: to study the hormonal status of women with infertility and PTSD.Materials and methods. 112 women with infertility were examined, who were divided into groups depending on the PTSD criteria. The I group included 36 women with PTSD criteria, who were diagnosed with infertility before the onset of the traumatic factor, the II group – 31 patients with fertility disorders which were diagnosed on the background of PTSD, the III group – 45 women with infertility and without signs of PTSD, the control group consisted of 50 healthy women who applied for a routine preventive examination.In all patients, on the 3rd–5th day of the menstrual cycle, the concentrations of prolactin, estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone were determined in the blood serum, in the saliva – cortisol, on the 21st day of the cycle – in the blood serum progesterone.Results. It was established that in women with infertility that was developed after the traumatic factor, the prolactin content is significantly higher (59.5±18.9 ng/ml) than in other groups of patients with fertility disorders (36.9±12.3 ng/ml in I group, 34.3±17.9 ng/ml – in the III group) and in the group of healthy women (13.5±5.6 ng/ml). The concentration of estradiol in the I group was within the reference values for the follicular phase of the cycle, but significantly lower (23.4±3.6 pg/ml) than in women of the other groups (from 87.6±14.6 pg/ml in the III group to 103.5±27.8 pg/ml in the group of healthy women). The average concentration of progesterone in the I (3.4±2.7 pg/ml) and II (4.1±2.9 pg/ml) groups was within the reference values, but was probably lower than that of healthy women (23.6±4.9 pg/ml), as well as women with infertility without signs of PTSD (19.4±5.1 pg/ml).In this study the patients with infertility which has developed on the background of PTSD had LH values within the reference normal range (2.0±0.5 U/L), but several times lower than in women with other reasons of infertility (12.0±3.6 U/l – in women with infertility before the development of PTSD, 6.0±1.9 U/l – in women with infertility without PTSD criteria) and in healthy women (9.2±3.4 U/l).An increased level of testosterone beyond the reference values was found only in women of the II group (3.3±1.9 nmol/l), in the other groups the average testosterone concentration ranged from 1.3±0.6 nmol/l in healthy women to 1.5±0.9 nmol/l in the I group and 1.8±0.7 nmol/l in women with infertility without signs of PTSD. Patients with PTSD are characterized by an increased level of cortisol in saliva, which indicates a prolonged reaction of the body to the trauma (8.8±0.3 ng/ml – in the I group, 10.3±0.4 ng/ml – in the II group), in groups without PTSD the level of this hormone in saliva was almost twice as low (5.4±0.2 ng/ml – in the III group and 5.9±0.3 ng/ml – in healthy women).Conclusions. 1. The patients with PTSD and infertility are characterized by high concentrations of cortisol in saliva and a decreased progesterone level in blood serum.2. In patients who had fertility disorders before a stressful event, a decreased estrogen concentration and an increased luteinizing hormone level were found in blood serum, which indicates endocrine disorders as a cause of infertility.3. Prolactin and testosterone levels were found to be higher in the patients with infertility that was developed after a traumatic event than in other women with reproductive function disorders. Both factors are pathogenetically related to the pathological reaction to stress.

Menopausal state and rheumatoid arthritis: a systematic review and meta-analysis.

Rheumatoid arthritis (RA) is a chronic inflammatory condition primarily affecting the joints. The higher prevalence of RA among females, combined with the known effects of sex hormones on immune function, has led researchers to investigate the potential relationship between menopausal status and the risk, severity, or progression of RA. This systematic review and meta-analysis aimed to determine the association between menopause and rheumatoid arthritis. In 2023, we conducted a comprehensive search across multiple databases, including Google Scholar, Scopus, PubMed/MEDLINE, Science Direct, Web of Science, EMBASE, Springer, and ProQuest. The search aimed to identify studies exploring the association between menopause and rheumatoid arthritis. Our analysis revealed that post-menopausal women had a higher risk of developing rheumatoid arthritis compared to pre-menopausal women, with an estimated odds ratio of 1.35 (95% CI: 1.04-1.67). Additionally, women who experienced early menopause (defined as onset before age 45) showed significantly higher odds of developing RA, with an odds ratio of 2.97 (95% CI: 1.73-4.22). These findings highlight the importance of considering menopausal status when assessing the risk of RA development in women. The results suggest that post-menopausal women, particularly those who experience early menopause, may be at higher risk for developing RA. Further research in this area could provide valuable insights into potential preventive measures and targeted interventions for high-risk individuals.

Comparative Analysis of The Effectiveness of Antihypertensive Therapy Including Spironolactone and Eplerenone in Patients With Essential Hypertension and Atrial Fibrillation.

To perform a comparative analysis of the efficacy of antihypertensive therapy (AHT) containing spironolactone or eplerenone in patients with essential arterial hypertension (AH) and atrial fibrillation (AF). The study included 99 male and female patients with essential AH complicated by permanent AF, who were receiving the outpatient treatment at the National Specialized Scientific and Practical Medical Center of Cardiology (Tashkent). The patients aged 61.3±9.5 years, the mean duration of AH was 12.9±8.3 years. All patients were divided into two groups: Group 1, patients who completed a 6-month combination AHT containing spironolactone (n=51); Group 2, patients who completed a 6-month combination AHT containing eplerenone (n=48). AF was diagnosed by electrocardiogram (ECG) and/or 24-hour ECG monitoring according to standard diagnostic criteria. The ECG study was performed in compliance with the American Society of Echocardiography Guidelines in M- and B-modes. The degree of structural vascular alterations was determined by the intima-media thickness of the common carotid artery by duplex scanning and microalbuminuria in morning urine. The concentrations of sex hormones were measured by the enzyme immunoassay. The serum concentrations of lipids, glucose, creatinine, and uric acid were measured by the enzymatic method. The glomerular filtration rate (GFR) was calculated with the EPI formula. Results of all studies were considered statistically significant at p&lt;0.05. The proportion of patients who achieved the target diastolic blood pressure (BP) values was significantly greater in the eplerenone-containing treatment group than in the spironolactone-containing treatment group: 87.8% vs. 67.5% (p=0.043). The proportion of patients who simultaneously achieved the target systolic and diastolic BP values was slightly greater in the eplerenone-containing treatment group than in the spironolactone-containing group (100% vs. 92.1%, p=0.060). The best cardioprotective efficacy was observed in the group of combination AHT containing eplerenone. Specifically, in Group 2, the left ventricular ejection fraction (LVEF) was significantly improved compared to Group 1: from 55.4±10.6% at baseline to 52.6±9.1% in Group 1 (p&gt;0.05) and from 54.8±8.8% at baseline to 58.2±6.4% in Group 2 (p&lt;0.02). Only in Group 2, the left atrial volume index (LAVI) was significantly decreased compared to Group 1. Thus, in Group 1, the LAVI changed from 42.2±15.1 ml/m2 at baseline to 40.4±12.2 ml/m2 (p&gt;0.05) and in Group 2, from 41.2±15.3 ml/m2 at baseline to 37.3±13.5 ml/m2 after the treatment (p&lt;0.05); the ∆% LAVI in the eplerenone group was -5.9% vs. -0.36% in the spironolactone group. In men of Group 1, estradiol significantly increased from 13.9±12.6 pmol/l at baseline to 22.7±12.4 pmol/l (p&lt;0.001). The good antihypertensive efficacy of the 6-month combination therapy containing eplerenone was significantly superior to spironolactone in achieving the target BP values. The eplerenone-containing treatment significantly improved LVEF and decreased LAVI compared to the spironolactone-containing treatment. A trend towards a beneficial effect of the AHT containing eplerenone on concentrations of sex hormones was noted in both women and men.

Evaluating the Prevalence of Migraine Headache among Patients with Female-Pattern Baldness

Background: According to WHO, migraine is a neurological disorder that has ranked third among the most prevalent medical conditions. Androgenetic alopecia (AGA), on the other hand, is a patterned hair loss disorder due to excessive response to androgens, affecting about half of the world's population. This disorder is presented by progressive hair loss in males and females after puberty, and sex hormones influence both diseases. Methods: A total of 50 women with clinically diagnosed AGA and a mean age of 37.5 referring to dermatology outpatient clinics of Shiraz University of Medical Sciences during 2020 were included in this study. The control group consisted of 50 women of similar age without alopecia. Hair loss was evaluated using the Ludwig classification, and the Persian versions of migraine screen questionnaire (MS_Q) and migraine disability assessment tests (MIDAS) were used to assess migraine among participants. Pain intensity was also measured using the Visual Analog scale (VAS). Results: According to the MS_Q Questionnaire, seven females (14%) in the case group and six females (12%) in the control group had migraines, and no significant correlation was observed between migraine and AGA (P = 0.766). There was no significant correlation between Ludwig score and migraine disability score in the case group with migraine (Spearman correlation coefficient = 0.367, P = 0.419). The only significant positive correlation was between Ludwig score and visual analog scale (VAS) in the case group with migraine (Spearman correlation coefficient = 0.844, P = 0.017) Conclusions: Based on the results, no significant correlation was found between migraine and androgenetic alopecia.

Gender-specific association between circulating serum Klotho and metabolic components in adults

BackgroundKlotho plays a pivotal role in human aging. Metabolic syndrome (MetS) is composed of multiple conditions that are also risk factors for cardiovascular disease and diabetes. We try to discuss gender-specific differences in Klotho and the associations between Klotho and MetS components.Materials and methodsThe National Health and Nutrition Examination Survey database from cycle 2015–2016 was analyzed. MetS was defined according to the 2005 updated criteria by the American Heart Association and National Heart Lung and Blood Institute. Gender-specific differences in serum Klotho, and associations between Klotho level and MetS components were examined.ResultsA total of 2475 participants (40–79 years old) with comprehensive data were included (52% women). In general, lower Klotho was associated with advanced age, male sex, tobacco use, elevated triglycerides, renal insufficiency, inflammation, low estradiol, and low sex hormone-binding globulin (SHBG). The correlation between MetS and Klotho was more obvious in women, mainly in waist circumference and triglyceride. There were no gender-specific differences in the associations between Klotho and renal dysfunction, but multivariate linear regression analysis showed gender differences in other factors associated with Klotho. Estradiol, SHBG, high-density lipoprotein cholesterol (HDL), and high-sensitivity C-reactive protein (CRP) were associated with Klotho levels independent of age and renal function in men, whereas in women, Klotho was independently associated with triglycerides and white blood cell count.ConclusionKlotho levels had gender disparities regardless of age, renal function, and sex hormones. In the current cohort, triglycerides were the major component of MetS that was independently associated with serum Klotho levels, and the association was particularly seen in women. However, HDL was found to be the male-specific MetS component independently associated with Klotho.

Hyperandrogenism and anthropometric parameters in women with polycystic ovary syndrome

ObjectiveOne of the main features of polycystic ovary syndrome (PCOS) is increased adipose tissue, which can result in hormonal disturbances. In the present study, we aimed to investigate which indicator of obesity could better associate with hormonal disturbances in PCOS women.MethodsIn this cross-sectional analysis, women with PCOS were included according to the Rotterdam criteria. Fasting blood samples were analyzed for biochemical, metabolic, and hormonal parameters. Anthropometric measures comprised body composition indices (assessed by bioelectric impedance analysis [BIA]), waist circumference, body mass index (BMI), and waist-to-height ratio (WHtR). Linear regression modeling was used to assess the association between anthropometric indices and hormonal imbalance, adjusted for age, mensuration status, and the homeostasis model assessment-estimated insulin resistance (HOMA-IR). Receiver operating characteristics (ROC) curves were utilized to ascertain the sensitivity, specificity, and optimal cut-off points of various anthropometric indices in identifying hyperandrogenism.ResultsA total of 129 PCOS women with a median (interquartile range [IQR]) age of 32.0 (23.0–32.0) years and a median BMI of 26.3 (23.00-29.70) kg/m2 were enrolled. In the adjusted linear regression model, BMI (β = 0.053, P < 0.001), waist circumference (β = 0.021, P = 0.001), WHtR (β = 3.325, P = 0.002), total fat mass (β = 0.021, P = 0.002), trunk fat mass (β = 0.038, P = 0.006), and leg fat mass (β = 0.045, P = 0.004) were positively associated with free androgen index (FAI). In addition, BMI (β=−0.017, P = 0.003), waist circumference (β=−0.008, P = 0.002), WHtR (β=−1.167, P = 0.004), total fat mass (β=−0.008, P=0.003), trunk fat mass (β=−0.017, P=0.001), and leg fat mass (β=−0.018, P=0.004) were negatively associated with the serum level of sex hormone binding globulin (SHBG). WHtR showed the greatest area under the curve (AUC) value (AUC = 0.676, P = 0.001) for identifying hyperandrogenism (FAI ≥ 4.97 or total testosterone ≥ 0.7 ng/mL) in PCOS women with corresponding sensitivity of 87.30% and specificity of 39.70%.ConclusionsWHtR is related to hyperandrogenism in PCOS better than other anthropometric measures.
