Resection of liver metastases from differentiated thyroid cancer: who might benefit? A report of 2 cases with review of literature.

Background: Liver metastases of differentiated thyroid cancers (DTC) are uncommon. Surgery has proven to be effective in patients with 131I-negative hepatic lesions. Here, we present two patients who underwent liver resection for metastatic DTC.

Accuracy of the European Thyroid Imaging Reporting and Data System (EU-TIRADS) in the valuation of thyroid nodule malignancy in reference to the post-surgery histological results.

Purpose: To assess the clinical usefulness of the European Thyroid Imaging and Reporting Data System (EU-TIRADS) in the valuation of thyroid nodules malignancy in reference to post-surgery histological results.

Material And Methods: Pre-operative ultrasound was performed in consecutive patients admitted for thyroid surgery between June 2017 and January 2018. Thyroid nodules were classified according to EU-TIRADS to five groups: 1-5.

Association between GWAS-Derived rs966423 Genetic Variant and Overall Mortality in Patients with Differentiated Thyroid Cancer.

Purpose: Five germline genetic variants (rs116909374, rs965513, rs944289, rs966423, and rs2439302) have been associated in genome-wide association studies (GWAS) with increased risk of differentiated thyroid cancer (DTC), but their role in mortality of patients has not been established. Also, no preoperative marker of the clinical outcome of thyroid cancer had yet been identified. The aim of the study was to investigate the relationship between the variants and overall mortality in patients with DTC.

In-depth characterization of the microRNA transcriptome in normal thyroid and papillary thyroid carcinoma.

Context: A single microRNA gene may give rise to several mature products that differ in length, called isomiRs. IsomiRs are known to be tissue specific and functionally relevant. The microRNA sequence heterogeneity of the thyroid gland has yet to be determined.

Systemic inflammation in peripheral arterial disease with or without coexistent chronic obstructive pulmonary disease: analysis of selected markers.

Introduction: Low-grade systemic inflammation plays an important role in the pathogenesis and natural history of chronic obstructive pulmonary disease (COPD) and peripheral arterial disease (PAD). The aim of the study was to analyze plasma concentrations of selected markers of inflammation in patients suffering from PAD with or without coexistent COPD.

Material And Methods: Thirty patients (6 women) with advanced PAD (at least IIb stage according to Fontaine scale) hospitalized due to critical limb ischemia were examined.

[Prevalence and difficulties in chronic obstructive pulmonary disease diagnosis in patients suffering from severe peripheral arterial disease].

Unlabelled: Cigarette smoking is the most prominent risk factor for chronic obstructive pulmonary disease (COPD) and peripheral arterial disease (PAD). Prevalence of COPD among cigarette smokers is about 23% in Poland. Effort dyspnea which develops in advanced stage of COPD is the leading cause of seeking medical advice.

Thyroid sialyltransferase mRNA level and activity are increased in Graves' disease.

Sialylation of cell components is an important immunomodulating mechanism affecting cell response to hormones and adhesion molecules. To study alterations in sialic acid metabolism in Graves' disease (GD) we measured the following parameters in various human thyroid tissues: lipid-bound sialic acid (LBSA) content, ganglioside profile, total sialyltransferase activity, and the two major sialyltransferase mRNAs for sialyltransferase-1 (ST6Gal I) and for sialyltransferase-4A (ST3Gal I). Fragments of toxic thyroid nodules (TN), nontoxic thyroid nodules (NN) and nontumorous tissue from patients with nodular goiter or thyroid cancer were used as a control (C).

Pax-8 expression correlates with type II 5' deiodinase expression in thyroids from patients with Graves' disease.

Transcription factors TTF-1 and Pax-8 control the expression of thyroid-specific genes crucial for thyroid function. It has been postulated that they may play a role in thyrotropin (TSH)-mediated augmentation of gene expression observed in some thyroid diseases including Grave's hyperthyroidism. Recently, we and others described the expression of two genes participating in thyroid hormone metabolism type I and type II deiodinase (D1 and D2, respectively) that are upregulated by TSH, although the mechanisms responsible for this effect are likely to be different.
