Analysis of Cancer Stem Cell Markers in Various Histological Subtypes of Adrenocortical Cancer.

Adrenocortical cancer (ACC) is a rare malignant neoplasm originating from the adrenal cortex, presenting limited therapeutic options. An avenue for improving therapeutic efficacy may involve a deeper understanding of the role of adrenocortical stem/progenitor cells in the pathogenesis of this disease. Although existing data suggest stem/progenitor characteristics in certain cell populations within ACC, the challenge remains to identify adrenocortical stem cell markers directly involved in its carcinogenesis.

Analysis of Bone Phenotype Differences in MEN1-Related and Sporadic Primary Hyperparathyroidism Using 3D-DXA.

The rarity and variability of MEN1-related primary hyperparathyroidism (mPHPT) has led to contradictory data regarding the bone phenotype in this patient population. A single-center retrospective study was conducted among young age- and sex-matched patients with mPHPT and sporadic hyperparathyroidism (sPHPT). The main parameters of calcium-phosphorus metabolism, bone remodeling markers, and bone mineral density (BMD) measurements were obtained during the active phase of hyperparathyroidism before parathyroidectomy (PTE) and 1 year after.

Cardiovascular and metabolic status in patients with primary hyperparathyroidism: a single-center experience.

Introduction: Cardiovascular diseases (CVD) and metabolic disorders (MD) have retained leading positions in the structure of morbidity and mortality for many years. Primary hyperparathyroidism (PHPT) is also associated with a greater incidence of CVD and MD. The aim of the present study was to describe the prevalence and structure of CVD and MD in hospitalized patients with PHPT and to search for possible associations between these pathologies.

The new histological system for the diagnosis of adrenocortical cancer.

Introduction: Adrenocortical cancer (ACC) is a rare malignant tumor that originates in the adrenal cortex. Despite extensive molecular-genetic, pathomorphological, and clinical research, assessing the malignant potential of adrenal neoplasms in clinical practice remains a daunting task in histological diagnosis. Although the Weiss score is the most prevalent method for diagnosing ACC, its limitations necessitate additional algorithms for specific histological variants.

The Russian registry of primary hyperparathyroidism, latest update.

Introduction: Until recently no major epidemiological research of primary hyperparathyroidism (PHPT) has been conducted in the Russian Federation, this led to the creation of the Russian online registry. The objective of this study is to estimate the clinical and biochemical profile, classical and non-classical complications, surgical intervention and medical therapy of the patients with different forms of PHPT in the Russian Federation.

Materials And Methods: The cross-sectional, observational, continuous study was conducted at the Endocrinology Research Centre (Moscow).

Mathematical model for preoperative differential diagnosis for the parathyroid neoplasms.

Background And Objective: Preoperative diagnosis of parathyroid carcinoma (PC) is critical for the determination of the scope of surgical intervention. Nowadays, specific diagnostic markers for differentiation of PC and benign tumors are unknown, and less than half of patients with PC undergo necessary surgery. The aim of this study was to develop the instrument for preoperative diagnosis of PC.

The Russian Registry of Chronic Hypoparathyroidism.

Introduction: Chronic hypoparathyroidism is a relatively rare disease associated with multicomponent medical therapy and various complications. The analysis of large databases of patients with chronic hypoparathyroidism is a necessary tool to enhance quality of medical care, as well as to determine the optimal clinical and therapeutic approaches, and prognostic markers of the disease.

The Aim: of this study is to estimate the clinical and biochemical profile, long-term complications, medical therapy and disease control of the patients with chronic postsurgical and non-surgical hypoparathyroidism.
