: Thyroid nodules are commonly found through sensitive imaging methods like ultrasonography. While most nodules are benign and asymptomatic, certain characteristics may indicate malignancy, prompting fine needle aspiration biopsy. Factors like age and gender affect cancer risk, complicating ultrasound-based risk systems.

Vitamin D is a steroid hormone, essential for the immune system and bone health. Since the sun is meant to provide at least 80% of daily vitamin D requirements, the COVID-19 pandemic is likely to have induced a considerable influence on calcium metabolism. We analyzed data from 1138 children, seen in an outpatient pediatric endocrinology clinic from 2022-2023.

Purpose: Ultrasonography (US) is the most accurate and cost-effective imaging method for identifying thyroid nodules. The difficulty in determining which nodules to sample for fine-needle aspiration (FNA) cytology has prompted the introduction of the Thyroid Imaging Reporting and Data Systems (TIRADS), which assesses the malignancy risk associated with thyroid nodules. Real-time elastography (RTE), coupled with strain ratio (SR) measurements, offers a means to evaluate the nodule stiffness and potentially discern their likelihood of being malignant.

Background: The generation of functionally active, stable T regulatory cells (Tregs) is a crucial target of type 1 diabetes (T1D) immunotherapy. This study investigated therapeutic intervention for T1D/Latent autoimmune diabetes in adults (LADA), wherein the diabetogenic proinflammatory Treg (intermediate) cell subset was characterized and driven to a Treg phenotype (CD4CD25FOXP3). This involved simultaneous inhibition of the eukaryotic initiation factor 5a (eIF5a) and Notch pathways using GC7 (N1-Guanyl-1,7-diaminoheptane) and Anti-DLL4 (Delta-like-ligand-4).

Structural incomplete response (SIR) (persistence/recurrence) may occur in 2-6% of low-risk differentiated thyroid cancer (DTC)-cases and in 67-75% of high risk. Regarding locoregional disease, surgery is the optimal therapeutic modality if the smallest dimension of the targeted node is ≥8 mm or ≥10 mm (central or lateral compartment). In the presence of smaller nodes, contraindications or the patient's unwillingness for reoperation, active surveillance (AS) or minimally invasive treatments (MITs) may be considered.

Purpose: Levothyroxine (LT4) is commonly prescribed, but there is evidence strongly suggesting that a significant proportion of these patients are on treatment without solid evidence of hypothyroidism. Small trials on treatment discontinuation, did not detect any predictors of success. Therefore, we conducted this study in an attempt to identify predicting factors for successful LT4 withdrawal.

Polycystic ovary syndrome (PCOS) is a common endocrinopathy worldwide with a heterogeneous clinical presentation including reproductive, metabolic, and endocrine elements. However, the assessment and management of PCOS remains inconsistent, with many women undiagnosed and untreated. We now also understand that the management of PCOS should extend throughout a woman's lifespan as many elements of the syndrome persist after menopause.

Background: Parathyroid adenoma is the most common cause of hypercalcemia and rarely leads to a hypercalcemic crisis, which is an unusual endocrine emergency that requires timely surgical excision.

Case Presentation: A 67-year-old male was admitted to the ER of the Euroclinic Hospital, Athens, Greece, because of elevated calcium levels and a palpable right-sided neck mass, which were accompanied by symptoms of nausea, drowsiness, and weakness for six months that increased prior to our evaluation. A gradual creatinine elevation and decreasing mental state were observed as well.

Article Synopsis
  • Vitamin D testing and supplement usage have increased significantly, yet many patients still remain deficient in vitamin D (less than 30 ng/mL).
  • A study analyzed data from 6,912 patients between 2014 and 2022, finding that while testing rates rose from 42.1% to 92.7%, only 25.5% achieved adequate vitamin D levels by 2022.
  • Current users of high-dose supplements for over 12 months showed the best results, but overall, only a minority of patients reached sufficient vitamin D levels despite increased testing and usage.

Achieving optimal glucose control in individuals with type 1 diabetes (T1DM) continues to pose a significant challenge. While continuous insulin infusion systems have shown promise as an alternative to conventional insulin therapy, there remains a crucial need for greater awareness regarding the necessary adaptations for various special circumstances. Nutritional choices play an essential role in the efficacy of diabetes management and overall health status for patients with T1DM.

Background: In the last decade, the combination of the widespread use of streptavidin-biotin technology and biotin-containing supplements (BCS) in the daily clinical practice, have led to numerous reports of erroneous hormone immunoassay results. However, there are no studies assessing the clinical and biochemical significance of that phenomenon, when treating patients with hypothyroidism. Therefore, a prospective study was designed to investigate the potential alterations in the measurement of thyroid hormone concentrations and clinical consequences in patients with hypothyroidism using low -dose BCS containing less than 300 μg/day.

Background: Thyroid nodules are an extremely common entity, and surgery is considered the ultimate diagnostic strategy in those with unclear malignant potential. Unfortunately, strategies aiming to predict the risk of malignancy have inadequate specificity. Our group recently found that the microenvironment of thyroid cancer is characterized by an enhanced immune invasion and activated immune response mediated by double-negative T lymphocytes (DN T) (CD3CD4CD8), which are believed to enable or promote tumorigenesis.

Background: Higher-but-within-normal thyrotropin (thyroid-stimulating hormone, TSH) is associated with higher risk for differentiated thyroid cancer (DTC) in surgical series. Our recent clinical observations suggest that this is not the case in the presence of autoimmune thyroid disease (AITD). We designed the present study to clarify this controversy.

Incidental finding of differentiated thyroid microcarcinomas (DTMc) in patients undergoing thyroid surgery for benign indications has become increasingly common. Even though carcinogenesis might relate to the background disease of the gland, the incidence of DTMc in the setting of various thyroid disorders remains unclear. We designed the present study to address this question.
