OBJECTIVE: Changes in postmenopausal hormone levels are associated with a variety of disorders. This study elucidated the mechanism by which follicle-stimulating hormone (FSH) increases cortisol production involved in development of menopause-related diseases. METHODS: The expression of FSH receptors (FSHRs) in murine adrenal zona fasciculata (AZF) cells and ATC7 cells was verified by immunofluorescence, western blotting and RT-PCR. The function of FSHR in promoting cortisol production was analyzed by cell culture and molecular biological methods...

Obstructive sleep apnoea (OSA) is regarded as a major health condition, progressively affecting an increased number of people around the world. The interplay between OSA and type 2 diabetes mellitus (T2DM) has been extensively studied. However, little is known on the relationship between OSA and type 1 diabetes mellitus (T1DM). This review provides an insight into the prevalence of OSA in T1DM and its relationship with diabetic complications. Studies have hitherto yielded contradictory results on the occurrence of OSA in T1DM...

AIMS: To assess the relationship between the left ventricular remodeling parameters of cardiac magnetic resonance and NT-pro-BNP in patients with primary aldosteronism (PA). METHODS: Seventy-four PA and 39 essential hypertension patients were prospectively recruited and underwent cardiac magnetic resonance. Plasma NT-pro-BNP was measured before patients underwent cardiac magnetic resonance. Left ventricular remodeling parameters were defined as left ventricular function parameters, T1 mapping parameters, and strain parameters...

INTRODUCTION: Passive heat treatment has been suggested to improve glycaemic control in individuals with type 2 diabetes mellitus. Previous studies have predominantly focused on hot water immersion and traditional sauna bathing, as opposed to the more novel method of infrared-based sauna bathing. Here we assessed the impact of a single infrared sauna session on post-prandial glycaemic control in older individuals with type 2 diabetes mellitus. METHODS: In this randomized controlled crossover trial, 12 participants with type 2 diabetes mellitus (male/female: 10/2, age: 69±7 y, BMI: 27...

In recent years, a growing number of clinical and biological studies have shown that patients with type 2 diabetes mellitus (T2DM) are at increased risk of developing Parkinson's disease (PD). Prolonged exposure to hyperglycemia results in abnormal glucose metabolism, which in turn cause pathological changes similar to PD, leading to selective loss of dopaminergic neurons in the compact part of substantia nigra. Dihydromyricetin (DHM) is a naturally occurring flavonoid with various biological activities including antioxidant and hepatoprotective properties...

Diabetes mellitus is a leading cause of disability with adverse effect on the quality of life. It also affects occupational health by impacting on several work parameters. The aim of this narrative review is to discuss the relationship between diabetes and absenteeism, presenteeism, work impairment and unemployment. The association between work and diabetic complications such as neuropathic pain, diabetic foot, psychological issues and hypoglycemia due to treatment is also examined. Evidence points to a relationship of diabetes with absenteeism, reduced work productivity and, thus, overall work impairment...

OBJECTIVE: Is to evaluate the accuracy of thyroid imaging reporting and data system (ACR-TIRADS) and the Bethesda system for reporting cytopathology (TBSRCP) classifications in identifying or ruling out thyroid malignancy in relation to the gold standard (post-surgical pathology). METHODS: This is a Cross-sectional study included 573 patients with single or multiple thyroid nodules. Patients were evaluated using the TIRADS and the TBSRCP classification. The data were correlated to the post operative pathology in a cohort of patients who underwent surgery 77/573 (13...

Food-dependent Cushing's syndrome (FDCS) is a rare presentation of hypercortisolism from adrenal origin, mostly observed in primary bilateral macronodular adrenal hyperplasia (PBMAH) but also in some cases of unilateral adrenocortical adenoma. FDCS is mediated by the aberrant expression of glucose-dependent insulinotropic peptide (GIP) receptor (GIPR) in adrenocortical cells. GIP, secreted by duodenal K cells after food intake, binds to its ectopic adrenal receptor, and stimulates cortisol synthesis following meals...

The aim of this narrative mini-review is to discuss the association between peroneal nerve entrapment (PEN) and diabetes mellitus (DM). Generally, PEN is not a common cause of peripheral neuropathy in DM. Poor glycaemic control and DM duration are powerful risk factors for PEN. Underlying mechanisms involve neurodegeneration and entrapment of peroneal nerve. Patients tend to present with chronic leg pain, gradual foot drop, steppage gait, or weakness of ankle dorsiflexion. Electrodiagnostic and imaging studies are very useful in diagnosis in determining the level at which entrapment occurs...

Thyroid hormone replacement therapy in NPC.

BACKGROUND: Current guidelines recommend dopamine agonists (DA) as the primary therapeutic approach for prolactinomas; however, emerging evidence suggests that surgical intervention can also yield favorable outcomes. OBJECTIVE: To comprehensively evaluate prolactinoma patients undergoing surgical and medical treatments at our pituitary center. METHODS: Retrospective review of medical records from prolactinoma patients treated between 2015 and 2022 was performed...

Since the first description 60 years ago of Nelson syndrome, the way to consider corticotroph pituitary neuroendocrine tumors (PitNETs) after bilateral adrenalectomy has evolved. Today, it is globally acknowledged that only a subset of corticotroph PitNETs is aggressive. After adrenalectomy, corticotroph tumor progression (CTP) occurs in about 30 to 40% of patients during a median follow-up of 10 years. When CTP occurs, various CTP (CTPS) speeds can be obsersed. Using a simple metrics in patients with CTP, CTPS was reported to vary from few millimeters per year to up to 40 mm per year...

OBJECTIVE: Spermatozoa are susceptible to oxidative radicals when antioxidant defenses are inadequate. The extent to which oxidative radicals contribute to sperm damage in patients with acromegaly remains unclear. This study aimed to investigate and elucidate this relationship. METHODS: The overall status of oxidants and antioxidants in both seminal plasma and serum of patients with acromegaly compared to a control group of healthy individuals was investigated. In addition, sperm parameters, including important measures such as growth hormone and insulin-like growth factor-1 concentrations...

Maturity-onset diabetes of the young (MODY) is the most frequent monogenetic diabetes form. It is caused by mutations in genes important for the development and function of pancreatic beta-cells, resulting in impaired insulin secretion capacity. Up to now, 14 different types have been described. The inheritance pattern is autosomal dominant, leading to a strong family history with more than three affected generations. Young age at diagnosis and lack of pancreatic autoantibodies are further characteristics of MODY...

OBJECTIVE: This study investigated the onset and the choice of treatment in children with very early onset of type 1 diabetes mellitus (T1D). METHODS: The study included 5,763 patients from the German Diabetes Patient Follow-up registry with onset of T1D in the first 4 years of life from January 2010 - June 2022. The analysis included diabetes-specific parameters, anthropometric data, and mode of treatment at onset, within the first and second year of T1D. Three groups were compared according to age at onset (G1: 223 patients 6-<12 months, G2: 1519 patients 12-<24 months, G3: 4001 patients 24-48 months)...

PURPOSE: In this study, the changes in microvascular circulation caused by pregestational and gestational diabetes were observed, without focusing on retinal findings, to reveal the effect of diabetes regulation. METHODS: A total of 135 subjects were included: 30 with gestational diabetes (GDM), 30 pregestational diabetes (PGDM), 30 healthy pregnant normoglycemic subjects, and 45 healthy non-pregnant subjects. All subjects were examined by optical coherence tomography (OCT) and angiography...

The genetic landscape of corticotroph tumours of the pituitary gland has dramatically changed over the last 10 years. Somatic changes in.

Hyperandrogenemia in patients with Cushing's syndrome (CS) presents a diagnostic pitfall due to its rare occurrence and overlapping symptoms with more common conditions like polycystic ovary syndrome (PCOS). This review explores the significance of androgen dysregulation in CS, focusing on both classical and 11-oxygenated androgens. While classical androgens contribute to hyperandrogenism in CS, their levels alone do not fully account for clinical symptoms. Recent research highlights the overlooked role of 11oxC19 androgens, particularly 11OHA4 and 11KT, in driving hyperandrogenic manifestations across all CS subtypes...

Mild autonomous cortisol secretion (MACS) has thus far been associated with several comorbidities, among which osteoporosis and fractures appear to be highly prevalent. Recent guidelines for adrenal incidentalomas have updated the definition of MACS, currently formulated on serum cortisol after a 1-mg dexamethasone test above 1.8 µg/dL or 50 nmol/L. Previous studies on bone health in adrenal incidentalomas had adopted different definitions of MACS, which produced heterogenous results in terms of fracture prevalence...

INTRODUCTION: We previously showed that a 3-week oral Metformin (MET) treatment enhances the osteogenic potential of bone marrow stromal cells (BMSCs) and improves several bone histomorphometric parameters in Wistar rats with metabolic syndrome (MetS). However, the skeletal effects of extended periods of MET are still not completely elucidated. Hence, we investigated the impact of a prolonged (3-month) MET treatment on bone architecture, histomorphometric and biomechanics variables and osteogenic potential of BMSCs in Wistar rats with or without MetS...
