INTRODUCTION: Beyond growth acceleration, growth hormone (GH) therapy improves body composition of GH-deficient (GHD) children due to the interaction of GH with lipid and carbohydrate metabolism, possibly mediated by adipokines secreted by adipose tissue and ghrelin. To promote linear growth, it is essential to have normal phosphate homeostasis. Fibroblast growth factor 23 (FGF23) is a known regulator of serum phosphorus and may be responsible for the increased renal phosphorus reabsorption observed during GH therapy...

Metabolic-associated fatty liver disease (MAFLD) is a newly coined term that links the presence of liver steatosis (characterised by the accumulation of lipids in at least 5% of liver cells) with a condition of overall systemic metabolic dysfunction. MAFLD impacts 24-36% of the global population. As per the official guidelines, a diagnosis of MAFLD can be made when hepatosteatosis is accompanied by type 2 diabetes mellitus, overweight, obesity, or at least 2 other specific metabolic abnormalities (increased waist circumference, hypertension, dyslipidaemia, prediabetes, elevated C-reactive protein level, or increased homeostasis model assessment of insulin resistance: HOMA-IR)...

Iron is one of the essential microelements necessary for maintaining the body's homeostasis. It serves various roles, including being a crucial component in the proper structure of many enzymes and supporting the transport of oxygen and electrons. Its deficiency can lead to anaemia, which is a common clinical condition often associated with thyroid diseases. Iron deficiency is one of the most common nutritional deficiencies, and its prevalence is strongly associated with socioeconomic status. It is the primary cause of anaemia in 42% of children and 50% of women...

INTRODUCTION: Drug therapy for Graves' disease (GD) is the first-line treatment in Europe. The use of a specific regimen for the administration of anti-thyroid drugs (ATDs) is still controversial. The objective was to compare block-and-replace therapy (BRT) with a titration (T) regimen in terms of incidence of overt hypothyroidism and development of Graves' orbitopathy (GO) over 18 months of treatment. MATERIAL AND METHODS: Two databases (PubMed, Cochrane Library) and reference lists were searched...

INTRODUCTION: Lymphovascular invasion is an independent prognostic marker in papillary thyroid carcinomas. In addition, integrin β4 is associated with advanced progression and metastasis in many malignancies. We aimed to investigate the relationship between integrin β4 and lymphovascular invasion in papillary thyroid carcinoma. MATERIAL AND METHODS: 73 patients with papillary thyroid cancer (48 patients with lymphovascular invasion and 25 patients without) were included in our study...

Trenbolone is a synthetic analogue of testosterone, belonging to the nandrolone group. It has both a strong anabolic effect and a limited androgenic effect (i.e. an androgen and anabolic steroid - AAS). It is used illegally by professional or amateur athletes, who want to improve their athletic performance and appearance by increasing their muscle mass. Trenbolone, like other AASs, are harmful, with 90% of users experiencing injurious side effects. It acts systemically on the body, and as such, its side effects can manifest as symptoms from different systems...

The incidence of thyroid nodules is rising annually. Surgical treatment is effective, but often results in significant trauma, recurrent laryngeal nerve injury, hypoparathyroidism, and other complications. Recent years have seen significant breakthroughs in thyroid nodule ablation for treating thyroid diseases, although its application remains controversial. The objective was to review the development history and current research status of thyroid nodule ablation to provide a reference for future studies. The literature on thyroid nodule ablation was reviewed, analysing its advantages and disadvantages...

INTRODUCTION: Lymphocytic hypophysitis (LH) is a rare inflammatory disorder of the pituitary or/and hypothalamus with variable disease course: from spontaneous remission to pituitary atrophy. The diagnosis, treatment and follow-up remain challenging. The aim of the study is to present long-term data and an individualized therapeutic approach and propose an algorithm for the follow-up of patients with probable LH. MATERIAL AND METHODS: A retrospective analysis of 18 consecutive adult patients (13 W/5 M, mean age 45...

Mental anorexia nervosa is a rare, potentially severe, chronic, and recurrent mental disorder that occurs more often in women than in men, especially during the childbearing years. The disorder is associated with an increased risk of mortality, mainly related to the physical consequences of severe malnutrition and suicide. Malnutrition of the body can cause serious hormonal and somatic problems. Despite significant hormonal disturbances that reduce fertility, a woman with anorexia can become pregnant. A new phenomenon now seen with increasing frequency is pregorexia, an eating disorder associated with pregnancy...

INTRODUCTION: This study was aimed at establishing a pregnancy-specific lipid reference interval (RI) in pregnant women in a single-centre in the Beijing area of China, simultaneously exploring the predictive value of lipid levels in early pregnancy for gestational diabetes mellitus (GDM). MATERIAL AND METHODS: From October 2017 to August 2019, Peking University International Hospital established records for 1588 pregnant women, whose lipid profiles were determined during the first and third trimesters...

INTRODUCTION: The objective was to investigate the correlation between Epstein-Barr virus (EBV) and human papillomavirus (HPV) infection in the development of benign thyroid lesions. MATERIAL AND METHODS: 29 cases of Hashimoto's thyroiditis (HT), 133 cases of thyroid adenoma, and 34 cases of HT with thyroid adenoma paraffin embedded tissue samples were used for EBV and HPV quantitative detection. RESULTS: None of the tissue samples carried HPV DNA...

INTRODUCTION: Control attenuation parameters (CAP) can detect nonalcoholic fatty liver disease (NAFLD). Our previous study found that miR-192-5p could screen for acute pancreatitis (AP) in NAFLD patients. This study focused on the role of CAP and miR-192-5p in NAFLD of acute AP. MATERIAL AND METHODS: AP patients and controls were enrolled. Classification of AP patients into NAFLD/AP patients and non-NAFLD/AP was made based on the CAP value. CAP was measured by liver transient elastography...

INTRODUCTION: Obesity, type 1 diabetes mellitus (T1DM), and type 2 diabetes mellitus (T2DM) are metabolic diseases that continue to be a global problem. Testosterone levels in men are affected by several factors, including obesity and DM. Although the relationship between diabetes and testosterone is not fully understood, oxidative stress is thought to play a major role. The aim of this study was to compare serum testosterone levels and oxidative stress markers [total antioxidant status (TAS), total oxidant capacity (TOS), oxidative stress index (OSI), and ischaemic modified albumin (IMA)] among the control group and experimentally induced obese, T1DM, and T2DM rats...
