Subacute THYROiditis Related to SARS-CoV-2 VAccine and Covid-19 (THYROVAC Study): A Multicenter Nationwide Study.

Context: The aims of the study are to compare characteristics of subacute thyroiditis (SAT) related to different etiologies, and to identify predictors of recurrence of SAT and incident hypothyroidism.

Methods: This nationwide, multicenter, retrospective cohort study included 53 endocrinology centers in Turkey. The study participants were divided into either COVID-19-related SAT (Cov-SAT), SARS-CoV-2 vaccine-related SAT (Vac-SAT), or control SAT (Cont-SAT) groups.

The role of elastography in the assessment of thyroid nodules in acromegaly.

Background: Nodular thyroid disease is a frequent finding seen in patients with acromegaly. Ultrasound-elastography (US-E) appears to be a helpful tool for the diagnosis of thyroid cancer. The aims of this study were to evaluate thyroid nodules in acromegaly and to assess the diagnostic accuracy of US-E in detecting thyroid cancer in this population.

Real-time detection of acromegaly from facial images with artificial intelligence.

Objective: Despite improvements in diagnostic methods, acromegaly is still a late-diagnosed disease. In this study, it was aimed to automatically recognize acromegaly disease from facial images by using deep learning methods and to facilitate the detection of the disease.

Design: Cross-sectional, single-centre study.

The visceral adiposity index, lipid accumulation product, and plasma atherogenic index are associated with subclinical atherosclerosis in patients with newly diagnosed acromegaly.

Background: Acromegaly is a rare chronic endocrine disorder, the active form of which is associated with an increased risk of cardiovascular and metabolic disease. Therefore, early diagnosis and treatment of cardiovascular diseases in acromegaly patients are important in terms of morbidity and mortality. The aim of this study was to determine whether the visceral adiposity index (VAI), lipid accumulation product (LAP), and plasma atherogenic index (PAI) are early cardiovascular risk markers in patients with active acromegaly.

Prevalence and associated risk factors of simple renal cysts in primary hyperparathyroidism.

Purpose: Previous studies have pointed to the role of parathormone (PTH) in the development of simple renal cysts. However, there is insufficient evidence related to simple renal cysts in primary hyperparathyroidism (PHPT). Therefore, this study aimed to evaluate the prevalence and risk factors associated with renal cysts in PHPT patients.

Paradoxical GH increase during oral glucose load may predict overall remission in acromegalic patients.

Background: The nadir growth hormone (nGH) during the oral glucose tolerance test (OGTT) is the gold standard method for diagnosing acromegaly. A paradoxical growth hormone (GH) response to oral glucose (OG) in acromegaly can be observed. The role of the paradoxical GH response on how the patients with acromegaly respond to the treatment has been addressed in few studies.
