OBJECTIVE: To study myocardial thyroid hormone metabolism in patients with aortic valve stenosis (AS) undergoing aortic valve replacement and in patients with coronary artery disease (CAD) undergoing coronary artery bypass grafting surgery. CONTEXT: The human heart expresses the type 2 deiodinase (D2) that activates T4 to T3. At the same time, the inactivating type 3 deiodinase (D3) has been found in a rat model of right ventricular hypertrophy. It is not known whether the human myocardium metabolizes thyroid hormone...

BACKGROUND: Low-normal thyroid function within the euthyroid range may contribute to increased atherosclerosis susceptibility. The leptin/adiponectin (L/A) ratio is associated with cardiovascular disease and reflects adipose tissue dysfunction. Relationships of the L/A ratio with low-normal thyroid function are unknown. METHODS: Relationships of thyroid stimulating hormone (TSH) and free thyroxine (free T4) with leptin, adiponectin and the L/A ratio in euthyroid subjects were documented in 67 fasting subjects with metabolic syndrome (Mets) and 86 euthyroid subjects without MetS (TSH and free T4 levels within the institutional reference range)...

BACKGROUND: Ketogenic diet (KD), which is high in fat and low in carbohydrates, mimics the metabolic state of starvation and is used therapeutically for pharmacoresistant epilepsy. It is known that generation of triiodothyronine (T3) from thyroxine (T4) decreases during fasting periods. The aim of this study was to evaluate the thyroid function of children receiving KD for at least 1 year due to drug-resistant epilepsy. METHODS: A total of 120 patients [63 males, 52...

INTRODUCTION: Overt thyroid disease in pregnancy is associated with numerous maternal and neonatal complications including preterm birth. Less is known about the contribution of trimester-specific subclinical alterations in individual thyroid hormones, especially in late gestation, on the risk of preterm birth. Herein, we examined the associations between subclinical changes in maternal thyroid hormone concentrations (TSH, total T3, free and total T4), measured at multiple time points in pregnancy, and the odds of preterm birth in pregnant women without clinical thyroid disease...

The aim of current study was to evaluate the function of thyroid during diabetic acidosis, just after the treatment and two weeks after the treatment. This was the analytic study. The study subjects included 20 patients, aged 18-36 years old, with type1 diabetes and diabetic ketoacidosis. All subjects were evaluated for thyroid function tests such as triiodothyronine (T3), thyroxine (T4), T3 resin uptake (T3RU), free T3 (FT3), free T4 (FT4) and thyroid stimulating hormone (TSH), before treatment. After completing DKA treatment and two weeks after discharge, the thyroid function tests were repeated on the subjects and the results were analyzed using paired T-test, ANOVA or repeated measure and Pearson correlation tests...

A 33-year-old female is presented with the first case to our knowledge of new daily persistent headache (NDPH) with a large right benign non-toxic multinodular goiter causing carotid and vertebral compression with complete resolution of the headache immediately after thyroidectomy. Although this may be quite rare, hypothyroidism or hyperthyroidism causing NDPH, migraine, or an exacerbation of pre-existing migraine is not. Clinicians should consider routinely obtaining serum thyroid-stimulating hormone (TSH) and free T4 in patients with new onset frequent headaches or an exacerbation of prior primary headaches...

BACKGROUND: Perfluoroalkyl substances (PFASs) are pollutants that tend to accumulate in the environment and organisms. The animal and human studies to date have focused on thyroid function, but the results are inconsistent. METHODS: A sample of 118 mother-infant pairs was obtained from the Taiwan Birth Panel Study (TBPS). Cord blood PFASs levels were evaluated using the Waters ACQUITY UPLC system coupled with a Waters Quattro Premier XE triple quadrupole mass spectrometer, and cord blood thyroid hormones were assessed using a Roche Analytics E170 modular analyser (Roche Diagnostics, Mannheim, Germany)...

Millions of people consume betel nut for increased capacity of work. It contains arecoline which is highly toxic and has several untoward side effects on endocrine functions. In this article, the role of arecoline on thyroid function under metabolic stress was investigated in mice. Water or food-deprivation, each for 5 days, caused ultrastructural degeneration of thyro-follicular cells, evident from pycnotic nuclei, scanty rough endoplasmic reticulum and mitochondria followed by depletion of blood serum T3 and T4 levels with alteration of TSH level as compared with control...

Across the world, hospital nurses experience a high level of burnout. Exploring biochemical markers of burnout could help to understand physiological changes and may provide useful evidence for preventing burnout symptoms. The current study included 94 female nurses from one Chinese third-level hospital. The Maslach Burnout Inventory-General Survey (MBI-GS) was used to investigate burnout symptoms: emotional exhaustion, cynicism, reduced professional efficacy, as well as the burnout average. The HPT axis was tested by checking blood levels of thyroid-stimulating hormone (TSH), thyroxin (T4) and triiodothyronine (T3)...

PURPOSE: Although the relationship between atherosclerosis and overt hypothyroidism has been confirmed, it remains controversial in cases of subclinical hypothyroidism. Higher TSH and similar T4 suggest differences in set-points or differences due to diagnostic limitations regarding subclinical hypothyroidism. Endothelial dysfunction (ED) is a marker rather than a precursor of cardiovascular disease. Asymmetric dimethylarginine (ADMA) and endocan are known as novel markers of ED in various diseases...
