    Maintaining body homeostasis is a prerequisite for normal reproductive function, which is vital for the survival of the species and an important process of natural selection. Body weight is an independent regulator of the hypothalamic–pituitary–gonadal axis activity. © 2016, International Society of Gynecological Endocrinology.

    Background: Benign adrenal tumors are commonly discovered on cross-sectional imaging. Mild autonomous cortisol secretion (MACS) is regularly diagnosed, but its effect on cardiometabolic disease in affected persons is ill defined. Objective: To determine cardiometabolic disease burden and steroid excretion in persons with benign adrenal tumors with and without MACS. Design: Cross-sectional study. Setting: 14 endocrine secondary and tertiary care centers (recruitment from 2011 to 2016). Participants: 1305 prospectively recruited persons with benign adrenal tumors. Measurements: Cortisol excess was defined by clinical assessment and the 1-mg overnight dexamethasone-suppression test (serum cortisol: <50 nmol/L, nonfunctioning adrenal tumor [NFAT]; 50 to 138 nmol/L, possible MACS [MACS-1]; >138 nmol/L and absence of typical clinical Cushing syndrome [CS] features, definitive MACS [MACS-2]). Net steroid production was assessed by multisteroid profiling of 24-hour urine by tandem mass spectrometry. Results: Of the 1305 participants, 49.7% had NFAT (n = 649; 64.1% women), 34.6% had MACS-1 (n = 451; 67.2% women), 10.7% had MACS-2 (n = 140; 73.6% women), and 5.0% had CS (n = 65; 86.2% women). Prevalence and severity of hypertension were higher in MACS-2 and CS than NFAT (adjusted prevalence ratios [aPRs] for hypertension: MACS-2, 1.15 [95% CI, 1.04 to 1.27], and CS, 1.37 [CI, 1.16 to 1.62]; aPRs for use of ≥3 antihypertensives: MACS-2, 1.31 [CI, 1.02 to 1.68], and CS, 2.22 [CI, 1.62 to 3.05]). Type 2 diabetes was more prevalent in CS than NFAT (aPR, 1.62 [CI, 1.08 to 2.42]) and more likely to require insulin therapy for MACS-2 (aPR, 1.89 [CI, 1.01 to 3.52]) and CS (aPR, 3.06 [CI, 1.60 to 5.85]). Urinary multisteroid profiling revealed an increase in glucocorticoid excretion from NFAT over MACS-1 and MACS-2 to CS, whereas androgen excretion decreased. Limitations: Cross-sectional design; possible selection bias. Conclusion: A cardiometabolic risk condition, MACS predominantly affects women and warrants regular assessment for hypertension and type 2 diabetes. © 2022 American College of Physicians.

    Introduction Androgen insensitivity syndrome (AIS) belongs to disorders of sex development, resulting from complete or partial resistance to the biological actions of androgens in persons who are genetically males (XY) with normally developed testes and age-appropriate for males of serum testosterone concentration. Case Outline A 21-year-old female patient was admitted at our Clinic further evaluation and treatment of testicular feminization syndrome, which was diagnosed at the age of 16 years. The patient had never menstruated. On physical examination, her external genitalia and breast development appeared as completely normal feminine structures but pubic and axillary hair was absent. Cytogenetic analysis showed a 46 XY karyotype. The values of sex hormones were as in adult males. The multisliced computed tomography (MSCT) showed structures on both sides of the pelvic region, suggestive of testes. Bilateral orchiectomy was performed. Hormone replacement therapy was prescribed after gonadectomy. Vaginal dilatation was advised to avoid dyspareunia. Conclusion The diagnosis of complete androgen insensitivity is based on clinical findigs, hormonal analysis karyotype, visualization methods and genetic analysis. Bilateral gonadectomy is generally recommended in early adulthood to avoid the risk of testicular malignancy. Vaginal length may be short requiring dilatation in an effort to avoid dyspareunia. Vaginal surgery is rarely indicated for the creation of a functional vagina. © 2015, Serbia Medical Society. All rights reserved.

    Obesity is an epidemic that has led to a rise in the incidence of many comorbidities: among others, reduced fertility is often under-evaluated in clinical practice. The mechanisms underlying the link between reduced fertility and obesity are numerous, with insulin resistance, hyperglycaemia and the frequent coexistence of polycystic ovary syndrome being the most acknowledged. However, several other factors concur, such as gut microbiome alterations, low-grade chronic inflammation and oxidative stress. Not only do women with obesity take longer to conceive, but in vitro fertilization (IVF) is also less likely to succeed. We herein provide an updated state-of-the-art regarding the molecular bases of what we could define as dysmetabolic infertility, focusing on the clinical aspects, as well as possible treatment. © 2022 The Authors.

    Objective: Individual patients' data sharing requires interoperability, security, ethical, and legal compliance. The aim was to assess the landscape and sharing capacities between endocrine researchers. Design: A standardized survey (SurveyMonkey®) with 67 questions was sent to European Network for the Study of Adrenal Tumors centers. Methods: Answers were counted as absolute numbers and percentages. Comparisons between inclusiveness target countries (ITC) and non-ITC (defined by Cooperation in Science & Technology Action) were performed using Fisher's exact test. Results: Seventy-three centers from 34 countries answered the survey. Electronic health record (EHR) systems are now the main source of data (90%). However, significant variability was reported, entailing >35 EHR providers, and variable data collected. Variable stakeholders' implication for enabling data sharing was reported, with more lawyers (P = .023), patient representatives (P < .001), ethicists (P = .002), methodologists (P = .023), and information technology experts (P < .001) in non-ITC centers. Implication of information technologies experts for data collection and sharing was underwhelming (33%). Funding for clinical research was higher in non-ITC than in ITC for clinical trials (P = .01) and for registry-based and cohort studies (P = .05). However, for retrospective studies addressing a specific clinical question, the funding was either very low (<10%) or nonexistent for both ITC and non-ITC (37% and 46%, respectively), with no dedicated funding for information technology (86%) and ethical and regulatory aspects (88%). Conclusions: In the absence of dedicated funding for retrospective research, current requirements for data sharing are obstacles. © The Author(s) 2025.

Results: Seventy-three centers from 34 countries answered the survey. Electronic health record (EHR) systems are now the main source of data (90%). However, significant variability was reported, entailing >35 EHR providers, and variable data collected. Variable stakeholders' implication for enabling data sharing was reported, with more lawyers (P = .023), patient representatives (P < .001), ethicists (P = .002), methodologists (P = .023), and information technology experts (P < .001) in non-ITC centers. Implication of information technologies experts for data collection and sharing was underwhelming (33%). Funding for clinical research was higher in non-ITC than in ITC for clinical trials (P = .01) and for registry-based and cohort studies (P = .05). However, for retrospective studies addressing a specific clinical question, the funding was either very low (<10%) or nonexistent for both ITC and non-ITC (37% and 46%, respectively), with no dedicated funding for information technology (86%) and ethical and regulatory aspects (88%). Conclusions: In the absence of dedicated funding for retrospective research, current requirements for data sharing are obstacles. © The Author(s) 2025.

    Objective: A high prevalence of insulin resistance (IR) has proven to manifest in patients with adrenal incidentalomas (AI). It has been demonstrated that an increase in IR is related to the size of tumourous masses; additionally, luteinizing hormone (LH)-dependent adrenal pathologies are well documented in patients with LH-responsive adrenal tumours occurring under conditions of physiologically elevated LH. We hypothesized that an association between LH and insulin might play a role in adrenal tumourigenesis and steroidogenesis. Design: The aim of our study was to investigate the association between LH and IR; adrenal tumour size (ATS) and IR; LH and cortisol after the 1 mg overnight dexamethasone test (1 mg DST); and ATS and 1 mg DST cortisol in AI patients. This was a case-control study conducted in the Clinic for Endocrinology, Diabetes and Metabolic Diseases in Belgrade, Serbia. The total study group consisted of 105 menopausal women: 75 AI patients [27 with nonfunctional AI (NAI) and 48 with (possible) autonomous cortisol secretion ((P)ACS)] and 30 age-, BMI-, LH- and menopause duration-matched healthy control (HC) women. To estimate IR, we used homeostasis model assessment (HOMA-IR). Results: Luteinizing hormone and ATS are in a significant positive correlation with HOMA-IR and 1 mg DST cortisol in menopausal patients with AI and (P)ACS. Conclusions: Our data point to a possible cause-effect relationship between LH and insulin in patients with AI and (P)ACS adding to the body of evidence of their involvement in adrenal tumourigenesis and steroidogenesis. © 2017 John Wiley & Sons Ltd

    Aim: to test effects of estradiol (E2) 1 mg and drospirenone (DRSP) 2 mg in treatment of normal weight menopausal women with typical menopausal symptoms, hyperinsulinism, and grade I hypertension. Material and methods: The participants were 133 menopausal women, mean age 51.82 ± 3.25 years, body mass index (BMI) 24.9 ± 2.6 kg/m2, waist/hip 0.80 ± 0.05, amenorrhoeic period 2.12 ± 2.10 years. All patients were treated with E2 1 mg and DRSP 2 mg during 12 months period. Blood samples were taken at 8 am before and during 12 months of therapy for: glycemia, lipids, hormonal analysis, follicle-stimulating hormone (FSH), luteinizing hormone (LH), E2, testosterone (T), prolactin (PRL), dehydroepiandrosterone sulfate (DHEAS), and sex hormone-binding globulin (SHBG). Oral glucose tolerance test (OGTT) was performed with 75 g glucose in order to assess insulin secretion. All had grade I hypertension 24 h blood pressure monitoring was performed before and after 12 months of therapy. Results: E2/DRSP significantly decreased total cholesterol, low-density lipoprotein (LDL), apolipoprotein B (ApoB), and increased high-density lipoprotein cholesterol (HDL) and apolipoprotein A (ApoA). Insulin area under the curve (AUC) significantly decreased (6586.1 ± 4194.2 vs. 5315.3 ± 2895.0, p <.05) and homeostatic model assessment (HOMA) (3.53 ± 2.18 vs. 3.0 ± 1.8, p <.05). FSH, LH decreased, E2 increased significantly. Of 24 h day blood pressure decreased significantly. Conclusions: E2/DRSP represents suitable therapy for hyperinsulinemic, grade I hypertensive menopausal women with typical symptoms and normal weight. © 2020 Informa UK Limited, trading as Taylor & Francis Group.

    Objective The aim of this study was to estimate insulin sensitivity (IS) in nondiabetic patients with adrenal incidentalomas (AI): nonfunctional adrenal incidentalomas (NAI) and patients with AI and subclinical Cushing's syndrome (SCS). Methods Based on the inclusion criteria (normal fasting glucose levels, no previous history of impaired fasting glucose and/or diabetes, and no medications or concomitant relevant diseases) and the exclusion criteria (pheochromocytoma, overt hypercortisolism, hyperaldosteronism, adrenal carcinoma, metastasis of extra-adrenal tumors, extra-adrenal malignancies), 142 subjects were drawn from a series of patients with AI. The subjects were age-, sex- and body mass index (BMI)-matched: 70 with NAI (50 women and 20 men), 37 with AI and SCS (31 women and 6 men) and 35 healthy control (HC) subjects (30 women and 5 men). The oral glucose tolerance test (OGTT) and several indices of insulin sensitivity (IS) were used: homeostasis model assessment (HOMA), quantitative insulin sensitivity check index (QUICKI), triglycerides and glucose index (TyG), index of whole-body insulin sensitivity (ISI-composite) and glucose to insulin ratio (G/I). Results There was a significant difference in IS between subjects with NAI and HC (HOMA, p = 0.049; QUICKI, p = 0.036; TyG, p = 0.002; ISI-composite, p = 0.024) and subjects with SCS and HC (AUC insulin, p = 0.01; HOMA, p = 0.003; QUICKI, p = 0.042; TyG, p = 0.008; ISI-composite, p = 0.002). There was no difference in the tested indices of IS between subjects with NAI and SCS (p > 0.05). However, subjects with SCS had a significantly higher prevalence of impaired glucose tolerance and higher area under the curve for glucose than subjects with NAI (p = 0.0174). The linear regression analysis showed that 1 mg-DST cannot be used as a predictor of HOMA (R2 = 0.004, F = 0.407, p = 0.525). Significant relationship was found between 1 mg-DST and ISI-composite (R2 = 0.042, F = 4.981, p = 0.028) but this relationship was weak and standard error of estimate was high. The linear regression model also showed that ACTH cannot be used as a predictor of HOMA (R2 = 0.001, F = 0.005, p = 0.943) or ISI-composite (R2 = 0.015, F = 1.819, p = 0.187). Conclusions Insulin resistance is a major cardiovascular risk factor; therefore, the assessment of IS in patients with AI, even nonfunctional, has a valuable place in the endocrine workup of these patients. © 2013 Elsevier Inc.

    Background: Disrupted sleep affects cardio-metabolic and reproductive health. Obstructive sleep apnea syndrome represents a major complication of obesity and has been associated with gonadal axis activity changes and lower serum testosterone concentration in men. However, there is no consistent opinion on the effect of obstructive sleep apnea on testosterone levels in men. Objective: The aim of this study was to determine the influence of obstructive sleep apnea on total and free testosterone levels in severely obese men. Materials and methods: The study included 104 severely obese (Body Mass Index (BMI) ≥ 35 kg/m2) men, aged 20 to 60, who underwent anthropometric, blood pressure, fasting plasma glucose, lipid profile, and sex hormone measurements. All participants were subjected to polysomnography. According to apnea-hypopnea index (AHI) patients were divided into 3 groups: <15 (n = 20), 15 - 29.9 (n = 17) and ≥ 30 (n = 67). Results: There was a significant difference between AHI groups in age (29.1 ± 7.2, 43.2 ± 13.2, 45.2 ± 10.2 years; p < 0.001), BMI (42.8 ± 5.9, 43.2 ± 5.9, 47.1 ± 7.8 kg/m2; p = 0.023), the prevalence of metabolic syndrome (MetS) (55%, 82.4%, 83.6%, p = 0.017), continuous metabolic syndrome score (siMS) (4.01 ± 1.21, 3.42 ± 0.80, 3.94 ± 1.81, 4.20 ± 1.07; p = 0.038), total testosterone (TT) (16.6 ± 6.1, 15.2 ± 5.3, 11.3 ± 4.44 nmol/l; p < 0.001) and free testosterone (FT) levels (440.4 ± 160.8, 389.6 ± 162.5, 294.5 ± 107.0 pmol/l; p < 0.001). TT level was in a significant negative correlation with AHI, oxygen desaturation index (ODI), BMI, MetS and siMS. Also, FT was in a significant negative correlation with AHI, ODI, BMI, age, MetS and siMS. The multiple regression analysis revealed that both AHI and ODI were in significant correlation with TT and FT after adjustment for age, BMI, siMS score and MetS components. Conclusion: Obstructive sleep apnea is associated with low TT and FT levels in severely obese men. © Copyright © 2021 Tančić-Gajić, Vukčević, Ivović, Marina, Arizanović, Soldatović, Stojanović, Đogo, Kendereški and Vujović.

    As type 2 diabetes mellitus (T2DM) is affected by both chronological and ovarian ageing, it is common in postmenopausal women. This review analyses and critically appraises the literature regarding the optimal therapeutic strategies for T2DM in women after menopause. Lifestyle interventions, including changes in dietary habits and physical exercise in everyday life targeting a modest weight loss (5%), represent the cornerstone of management. Limited intake of alcohol and sodium, as well as smoking cessation, are additional lifestyle changes for both endothelial and bone health. Regarding medications, postmenopausal women should be initially treated with metformin, concurrently with lifestyle intervention. If glycosylated haemoglobin (HbA1c) remains over the target level (usually ≥7%), dipeptidyl peptidase-4 inhibitors (DPP-4i) or glucagon-like peptide-1 receptor agonists (GLP-1RA) should be preferred. Thiazolidinediones (TZDs) and canagliflozin should be avoided in postmenopausal women with increased fracture risk. Insulin should be used with caution to avoid hypoglycaemia. Bariatric surgery is a well established and effective therapeutic option for both weight loss and glycaemic control in very obese patients with T2DM; however, metabolic benefits should be balanced against nutritional deficiencies that often present after surgery. Proper control of hypertension, with avoidance of hypotension, is of great importance as a measure against falls. Annual tests for retinopathy and neuropathy are crucial for the same reason. Menopausal hormone therapy (MHT) has a beneficial effect on glucose homeostasis, reduces the risk of new-onset T2DM and improves glucose control in women with T2DM. T2DM has been considered a cardiovascular disease equivalent, which meant that postmenopausal women with the disease could not take MHT but current evidence supports an individualised approach to this issue. Therapeutic strategies for women with T2DM after menopause should aim to maximise benefits for metabolic, cardiovascular and bone health with the minimum of adverse effects, bearing in mind that most women will spend more than one-third of their life being of postmenopausal status. © 2019 Elsevier B.V.
