OBJECTIVE: Thyroid hormones (THs) are primarily responsible for the regulation of energy homeostasis and metabolism. However, few prospective studies have assessed the association between THs and metabolic syndrome (MetS) in a general population. We therefore designed a cohort study to examine whether serum THs levels within the reference range are predictive factors for developing MetS in adults. DESIGN: Prospective cohort study. PARTICIPANTS: A prospective study (n=6,119) was performed in Tianjin, China...

INTRODUCTION: Thyroid hormone effects on many organs including central and peripheral nervous systems. However, these hormones do not affect all systems/organs to a similar extent. Thus, we conducted this study to explore the effect of thyroid hormones on somatic nervous system assessed by Nerve conduction study and cardiac autonomic activity assessed by heart rate variability. METHODS: The study included newly diagnosed hypothyroid patients and healthy controls...

BACKGROUND: The current therapies of thyroid-associated ophthalmopathy (TAO) were still a challenging matter. In this study, we aimed to contrast the impact of before- after rituximab (RTX) therapy in the patients with TAO. METHODS: We searched the PubMed, EMBASE, and SCOPUS databases for articles published up to July 3, 2017. Fixed- or random-effects meta-analysis was used to provide pooled estimates of standard mean difference (SMD) both the primary outcome from clinical activity score (CAS), and secondary outcomes from thyrotropin receptor antibody (TRAb), proptosis, thyroid stimulating hormone (TSH), and interleukin-6 (IL-6) levels...

BACKGROUND: Superior semicircular canal dehiscence (SSCD) is a bony defect in the osseous shell of the petrous temporal bone. The pathophysiological association between osteoporosis and SSCD remains poorly understood. We aim to investigate the relationships between serum calcium, 25-hydroxyvitamin D, and thyroid stimulating hormone levels, and symptoms in adult patients with SSCD treated through a middle fossa craniotomy. METHODS: Patient demographics and clinical parameters were collected...

As a feed additive, betaine is widely used in livestock production for its ability to promote growth. Our previous studies had reported that maternal betaine supplementation altered hepatic metabolism in offspring. But it remains unknown whether and how maternal betaine modulates metabolism of thyroid hormones in the offspring chickens by epigenetic modification. In this study, one hundred and twenty Rugao yellow-feathered laying hens were randomly divided into two groups, and were fed basal diet with or without 0...

Thyroid hormones (THs) play a critical role in normal maturation of the developing brain in the fetus and infant. Continuing advances in neonatal medicine have contributed to an increased survival of extremely premature infants with neonatal morbidities. In these infants, thyroid system immaturities, as well as morbidity-related thyroid dysfunction, contribute to transient hypothyroxinemia of prematurity (THOP), which is characterized by very low total and free thyroxine and normal or low thyroid stimulating hormone (TSH) levels...

Differences in thyroid function status within the euthyroid range have been proposed to affect the development of (subclinical) atherosclerosis [1], as evidenced by a greater carotid artery intima media thickness and progression of coronary artery calcification in the context of low normal thyroid function, i.e. a higher thyroid stimulating hormone (TSH) or a lower free thyroxine (FT4) thyroid hormone in the euthyroid range [2,3]. Importantly, with respect to high density lipoproteins (HDL) the concept is emerging that abnormalities in function rather than low concentrations of HDL cholesterol per se may give rise to impaired atheroprotective potential of this lipoprotein fraction...

Multiple osteolytic lesions are usually associated with metastatic involvement of the bone; however, metabolic bone diseases should also be included in the differential diagnosis. In this study, we describe a case of primary hyperparathyroidism (PHPT) with multiple osteolytic lesions that was diagnosed initially as having metastatic bone involvement. The laboratory results showed hypercalcemia and raised alkaline phosphatase along with fibrosis in the bone marrow biopsy with no increase in tumor markers and normal serum protein electrophoresis...

PURPOSE: L-Thyroxine is one of the most commonly prescribed drugs and accordingly used by many breast cancer patients with thyroid disorders. Hence, potential interactions of chemotherapy with L-thyroxine, possibly contributing to fatigue, would be of high clinical relevance. Therefore, we investigated fatigue and underlying pathways in L-thyroxine-using breast cancer patients during chemotherapy. METHODS: Thyroid-stimulating hormone (TSH), L-triiodothyronine (T3), and diurnal salivary cortisol patterns were analyzed in breast cancer patients in the beginning and at the end of adjuvant chemotherapy within the control group (n = 41) of a randomized exercise intervention trial...

A rare case of resistance to thyroid hormone (RTH) complicated with Graves' hyperthyroidism was reported. The management of this disease is similar to that of Graves' disease. Antithyroid drug therapy is the first choice, and iodine therapy and surgery are not recommended due to the possibility of severe hypothyroidism and enlargement of the pituitary gland.

BACKGROUND: There is a common perception that total thyroidectomy causes weight gain beyond expected age-related changes, even when thyroid replacement therapy induces a euthyroid state. The aim of this study was to determine whether patients who underwent total thyroidectomy for a wide spectrum of conditions experienced weight gain following surgery. METHODS: We retrospectively studied 107 consecutive total thyroidectomy patients treated between January 2013 and June 2014...

Recently, it was suggested that resveratrol (RES), a natural polyphenol, possesses beneficial therapeutic roles in depression. The aim of this review is to discuss the novel potential pharmacological effects of RES on depression. We first consider the pathophysiology of depression and then review the potential antidepressant effects of RES. Apart from the alternation of the monoaminergic system and the molecular markers related to depression, RES might exert an antidepressant-like effect through modulating the HPA axis, BDNF and synaptic vesicle proteins, inflammatory cytokines and oxidative stress, and thyroid hormones...

There is preclinical and recent epidemiological evidence that thyroid hormone supports breast cancer. These observations raise the issue of whether management of breast cancer in certain settings should include consideration of reducing the possible contribution of thyroid hormone to the advancement of the disease. In a preliminary experience, elimination of the clinical action of endogenous L-thyroxine (T 4 ) in patients with advanced solid tumors, including breast cancer, has favorably affected the course of the cancer, particularly when coupled with administration of exogenous 3,5,3'-triiodo-L-thyronine (T 3 ) (euthyroid hypothyroxinemia)...

Background and aim: Psoriasis vulgaris, a chronic inflammatory skin disease, requires a long term medication, in order to avoid relapsing episodes. TNF-alpha, one of the targeted molecule in psoriasis therapy, seems to be also involved in thyroid disorders etiopathogenesis. The aim of this study was to evaluate the relationship between anti TNF-alpha therapy and thyroid parameters: serum level of triiodothyronine (T3), free thyroxine (FT4), thyroid-stimulating hormone (TSH) and antithyroidperoxidase antibody (AbTPO) in psoriasis treated population...

The thyroid hormone receptors, TRα1, TRβ1, and other subtypes, are members of the nuclear receptor superfamily that mediate the action of thyroid hormone signaling in numerous tissues to regulate important physiological and developmental processes. Their most well-characterized role is as ligand-dependent transcription factors; TRs bind thyroid hormone response elements in the presence or absence of thyroid hormone to facilitate the expression of target genes. Although primarily residing in the nucleus, TRα1 and TRβ1 shuttle rapidly between the nucleus and cytoplasm...

Thyroglobulin (TG) is the most abundant thyroid gland protein, a dimeric iodoglycoprotein (660 kDa). TG serves as the protein precursor in the synthesis of thyroid hormones tetraiodothyronine (T4) and triiodothyronine (T3). The primary site for T3 synthesis in TG involves an iodotyrosine acceptor at the antepenultimate Tyr residue (at the extreme carboxyl-terminus of the protein). The carboxyl-terminal region of TG is comprised of the CholinEsterase-Like (ChEL) domain followed by a short unique tail sequence...

BACKGROUND: The potential endocrine-disrupting effects of perfluoroalkyl substances (PFASs) have been demonstrated in animal studies, but whether PFASs may interfere with body weight regulation in humans is largely unknown. This study aimed to examine the associations of PFAS exposure with changes in body weight and resting metabolic rate (RMR) in a diet-induced weight-loss setting. METHODS AND FINDINGS: In the 2-year POUNDS Lost randomized clinical trial based in Boston, Massachusetts, and Baton Rouge, Louisiana, that examined the effects of energy-restricted diets on weight changes, baseline plasma concentrations of major PFASs were measured among 621 overweight and obese participants aged 30-70 years...

PURPOSE: According to the American Thyroid Association guidelines in 2015, both an unstimulated thyroglobulin (u-Tg) below 0.2 ng/ml and a stimulated thyroglobulin (s-Tg) below 1.0 ng/ml were required along with negative imaging findings to define an excellent response. This study aimed to investigate whether a u-Tg below 0.2 ng/ml coincides with a s-Tg below 1 ng/ml. PATIENTS AND METHODS: A total of 290 patients with nonmetastatic differentiated thyroid cancer were retrospectively evaluated with a median follow-up of 36 months...
