Age-dependent effects of lockdown and post-lockdown periods on HbA1c during the COVID-19 pandemic: A 3-year longitudinal cohort study.

The impact of COVID-19 lockdown on glycemic control in patients with diabetes mellitus (DM) remains unclear. This study aimed to investigate the effects of lockdown measures on the metabolic parameters of patients with DM, with particular emphasis on geriatric populations. In this retrospective, longitudinal cohort study, 1224 patients were analyzed.

Assessing the predictive value of the suppressed 1 mg overnight dexamethasone suppression test in success of bariatric surgery.

Bariatric surgery has been proven to be a successful intervention for managing obesity. There are numerous studies in the literature aiming to predict the factors influencing the success of bariatric surgery. Our study aims to determine whether preoperative 1 mg overnight dexamethasone suppression test (1 mg-DST) serum cortisol levels can serve as predictors of the effectiveness of bariatric surgery in severe obese patients without Cushing syndrome.

Evaluation of Bone Turnover Markers Such as Osteoprotegerin, Sclerostin and Dickkopf-1 in Subclinical Hyperthyroidism.

In this study, it was aimed to assess effects of subclinical hyperthyroidism (SH) on bone metabolism using osteoprotegerin (OPG), sclerostin, Dickkopf-1 (DKK1) and biochemical parameters. This cross-sectional prospective study included 40 patients with SH and 40 euthyroid controls. Serum OPG, sclerostin, DKK-1, type-1 procollagen, C-terminal polypeptide (CTx) and 24-hours urine N-terminal telopeptide (NTx) were measures using ELISA kit.

The impact of insulin induced lipohypertrophy on carotid intima-media thickness in patients with type 2 diabetes mellitus.

Lipohypertrophy (LH) is a major localized complication of insulin therapy. We aimed to investigate the association between insulin-induced LH and carotid intima-media thickness (CIMT) in patients with type 2 diabetes mellitus (DM). A total of 75 patients with DM treated with insulin were included in this study.

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.

Evaluation of parenchymal vascularity of the thyroid gland with vascularization index by color superb microvascular imaging in patients with Graves' disease.

Aim Of The Study: To determine the parenchymal vascularity of the thyroid gland with color superb microvascular imaging in patients with Graves' disease, and compare the vascularization index values with healthy subjects.

Materials And Methods: The thyroid glands of 37 patients whose laboratory and clinical findings were consistent with Graves' disease, and 40 asymptomatic subjects with normal laboratory values, were examined using color superb microvascular imaging. Measurements of the vascularization index were performed with a free region of interest which was drawn along the outer margin of the gland on the color superb microvascular imaging mode.

Evaluation of the Stiffness of Thyroid Parenchyma With Shear Wave Elastography Using a Free-Region of Interest Technique in Graves Disease.

Objectives: The first aim was to evaluate the stiffness of thyroid parenchyma with shear wave elastography (SWE) in patients with Graves disease (GD) and compare the elastographic values with those of asymptomatic volunteers. The second aim was to evaluate whether there was a correlation between SWE values and grayscale ultrasound (US) and laboratory parameters.

Methods: In this prospective study, the thyroid gland parenchyma of 50 patients whose clinical and laboratory findings were indicative for GD and 54 asymptomatic participants with normal laboratory values was examined by SWE.

A rare cause of subclinical hypothyroidism: macro-thyroid-stimulating hormone.

Background Subclinical hypothyroidism is a situation in which the thyroid-stimulating hormone (TSH) value exceeds the upper limit of normal, but the free triiodothyronine (T3) and thyroxine (T4) values are within the normal range. The etiology is similar to overt hypothyroidism. Case presentation An 18-year-old female patient was referred to our endocrinology clinic due to elevated TSH levels detected during a routine examination.

Effects of Glucose Ingestion on Serum Fractalkine Levels in Healthy Subjects and Newly Diagnosed Type 2 Diabetic Patients.

Background: Fractalkine (FKN) is an inflammatory cytokine that has been shown with increased serum levels in diabetic patients and is considered to contribute to the adipose tissue inflammation by supporting monocyte adhesion to adipocytes which has an important role in the pathogenesis of type 2 diabetes mellitus (T2DM). Our aim was to evaluate the effects of glucose ingestion on the serum fractal - kine levels in healthy subjects with normal glucose tolerance (NGT) and newly diagnosed T2DM patients.

Methods: A total of 67 patients were included in this study, and they were divided into NGT (n=34) and T2DM (n=33) groups according to their oral glucose tolerance test (OGTT) results.
