INTRODUCTION: Thyroid carcinoma is the most frequent malignancy among endocrine-related tumours. Papillary thyroid carcinoma (PTC) is the main type of thyroid carcinoma, and almost 80% cases of thyroid carcinoma are diagnosed as PTC. The molecular mechanism underlying PTC progression is unclear. This study aims to investigate the potential mechanisms of zinc finger antisense 1 (ZFAS1) function in PTC. MATERIAL AND METHODS: The expression of ZFAS1 and p53 was determined by quantitative polymerase chain analysis (qPCR) in PTC tissues derived from 20 PTC patients...

Thyroid orbitopathy (TO) is the most common cause of orbital tissue inflammation, accounting for about 60% of all orbital inflammations. The inflammatory activity and severity of TO should be diagnosed based on personal experience and according to standard diagnostic criteria. Magnetic resonance imaging (MRI) of the orbit is used not only to identify swelling and to differentiate inflammatory active from non-active TO, but also to exclude other pathologies, such as orbital tumours or vascular lesions. However, a group of diseases can mimic the clinical manifestations of TO, leading to serious diagnostic difficulties, especially when the patient has previously been diagnosed with a thyroid disorder...

Fine needle aspiration biopsy (FNAB) guided by ultrasonography is routinely used to identify thyroid nodules prior to surgery. Although FNAB has great diagnostic accuracy and safety, it is limited by its relatively low diagnostic accuracy in follicular lesions, such as non-diagnostic or atypia of unclear significance (AUS)/follicular lesion of uncertain significance (FLUS). Additional diagnostic tests are required to overcome these challenges in evaluating thyroid nodules. Thyroid nodules can now be diagnosed with spring-activated single- or double-action needles following the introduction of core needle biopsy (CNB)...

INTRODUCTION: The high prevalence of obesity and thyroid diseases worldwide justifies di per se their simultaneous coexistence. In recent decades, there has been a parallel and significant rise in obesity and thyroid diseases in industrialised countries, although the underlying mechanisms are complex and not well known. MATERIAL AND METHODS: The authors accomplished a comprehensive literature search of original articles concerning obesity and thyroid status. Original papers exploring the association between these two morbidities in children and adults were included...

INTRODUCTION: Differentiated thyroid cancer (DTC) is the most common malignant tumour of the endocrine system. The aim of this study was to establish a nomogram for simply and effectively predicting DTC. MATERIAL AND METHODS: 464 inpatients who underwent thyroid nodule surgery were retrospectively analysed. Univariate logistic regression and multivariate logistic regression were used to analyse the risk factors of DTC. A nomogram was constructed for predicting DTC...

INTRODUCTION: Non-alcoholic fatty liver disease (NAFLD) is a global disease estimated to affect one-third of the world's population. NAFLD is the hepatic manifestation of metabolic syndrome. In recent years, formulations have been made using haematological laboratory parameters, and it has been reported to be associated with inflammation and fibrosis in the liver. In this study, we aimed to evaluate the neutrophil to high-density lipoprotein (HDL) cholesterol (HDL-C) ratio (NHR) in patients diagnosed with NAFLD by ultrasonographic imaging for the first time in the literature...

INTRODUCTION: The antifracture efficacy of vitamin D is still controversial. The aim of this systematic review was to examine if the vitamin D trials were designed adequately to reliably assess its antifracture activity. MATERIAL AND METHODS: The electronic databases PubMed, Medline, Embase, Web of Science, and Cochrane Library were searched to identify clinical trials evaluating the antifracture efficacy of vitamin D in adults. We compared the protocols of the trials against the opinions of the American Society for Bone and Mineral Research (ASBMR), International Society for Clinical Densitometry (ISCD), National Osteoporosis Foundation (NOF), European Medicines Agency (EMEA) experts, and the consensus statement from the 2nd International Conference on Controversies in Vitamin D, and against the protocols of the trials of the medications with proven antifracture efficacy (bisphosphonates, teriparatide, abaloparatide, raloxifene, denosumab, romosozumab)...

Obesity is currently one of the most serious public health problems which affects up to 30-40% of the population, and its prevalence is higher in men than in women. Complications of obesity include atherosclerosis, cardiovascular diseases, and type 2 diabetes mellitus, but it also has a negative impact on the hormonal system and fertility. The hormonal consequences of excess body fat in men are functional hypogonadism, which not only causes clinical symptoms of testosterone deficiency, but is also a risk factor for obesity (a vicious circle mechanism)...

INTRODUCTION: Recent studies have shown that a decline in isletβ cells quality is due to β-cell dedifferentiation, not only β-cell apoptosis. Angiotensin (1-7) [Ang(1-7)] could attenuate high glucose-induced apoptosis and dedifferentiation of pancreaticβ cells by combining with MAS receptors. However, the mechanism of such action has not been elucidated. Recent studies have revealed that Wnt/β-catenin and forkhead box transcription factor O1 (FoxO1) are associated with β-cell dedifferentiation...

INTRODUCTION: There have been many studies assessing whether abnormal metabolic and hormone levels among women with polycystic ovary syndrome (PCOS) are associated with a greater risk of non-alcoholic fatty liver disease (NAFLD). However, previous studies repported no consistent outcomes. To provide a comprehensive evaluation regarding the role of PCOS in the risk of NAFLD, we updated the published literature and conducted this systemic review and meta-analysis. MATERIAL AND METHODS: Electronic databases (Web of Science and PubMed) were searched for literature up to October 2022...

INTRODUCTION: Diabetic peripheral neuropathy (DPN) and autonomic neuropathy are commonly coexistent in patients with type 2 diabetes mellitus (T2DM). Current assessment tools for diabetic neuropathy remain complicated and limited. We aimed to investigate the sonographic changes of the cervical vagus nerve in DPN patients with T2DM. MATERIAL AND METHODS: Patients with T2DM were divided into a DPN group (DPN, n = 44) and non-DPN controls (NDPN, n = 43) based on electromyogram results...

INTRODUCTION: Our aims were to explore the relationship between primary hyperparathyroidism (pHPT) and malignant tumour development, to determine the frequency and the time of occurrence of malignant tumours in patients with pHPT, and to evaluate the characteristics of pHPT in these patients. MATERIAL AND METHODS: This retrospective cohort study included consecutive individuals who were diagnosed with pHPT aged 18 years or older in a university hospital during a 7-year period...
