Background: Central venous catheters (CVCs) are frequently used for monitoring haemodynamic status and rapidly delivering fluid therapy during the peri- and postoperative periods. Indwelling CVCs are typically used 7-14 days postoperatively for additional monitoring and treatment, but patients may develop asymptomatic catheter-related thrombosis, leading to life-threatening pulmonary embolism and death. Early detection helps to avoid such complications. Methods: This prospective observational study investigated the risk factors associated with catheter-related right internal jugular vein thrombosis in patients undergoing chest surgery...

Recently, long noncoding RNAs (lncRNAs) have been shown to be linked to regulate different biological processes, such as cell growth, differentiation and tumorigenesis. LncRNAs have been identified to be promising clinical biomarkers in various tumors. Long noncoding RNAs cancer susceptibility candidate 2 (CASC2) has recently been demonstrated to be correlated to tumorigenesis in renal cell carcinoma, lung carcinoma, glioma, and gastric carcinoma. Nevertheless, the research on the biological function and clinical significance of CASC2 in thyroid carcinoma are still unclear...

A euthyroid state in the brain is crucial for its adequate development and function. Impairments in thyroid hormones (THs; T3 or 3,5,3'-triiodothyronine and T4 or thyroxine) levels and availability in brain can lead to neurological alterations and to psychiatric disorders, particularly mood disorders. The thyroid gland synthetizes mainly T4, which is secreted to circulating blood, however, most actions of THs are mediated by T3, the transcriptionally active form. In the brain, intracellular concentrations of T3 are modulated by the activity of type 2 (D2) and type 3 (D3) deiodinases...

Perfluoroalkyl substances (PFAS), chemicals used to make products stain and stick resistant, have been linked to health effects in adults and adverse birth outcomes. A growing body of literature also addresses health effects in children exposed to PFAS. This review summarizes the epidemiologic evidence for relationships between prenatal and/or childhood exposure to PFAS and health outcomes in children as well as to provide a risk of bias analysis of the literature. A systematic review was performed by searching PubMed for studies on PFAS and child health outcomes...

Previous meta-analysis has not shown different effects of miR-608 rs4919510 polymorphism in specific cancer types and reported no significant association between rs4919510 and cancer risk among Chinese. However, more recent findings have been inconsistent. Therefore, we performed an updated meta-analysis to examine whether this polymorphism is associated with cancer risk based on ethnicity and type. A total of 18 case-control studies, comprising 12,517 cases and 15,624 controls, were included in our study. Surprisingly, in contrast with previous meta-analysis, a significant association between the rs4919510 polymorphism and cancer risk was observed in Chinese (CG vs CC: odds ratio = 1...

Papillary thyroid carcinoma is the most common malignant neoplasm of the thyroid gland, accounting for 50-89% of the cases. It usually presents as a well-differentiated, slow-growing, malignant disease with common spread to locoregional lymph nodes and high recurrence rates. In patients with limited cervical lymph node metastases who are not candidates for surgery or radioiodine therapy, percutaneous ethanol injection (PEI) guided by ultrasonography has proven to be a valuable treatment alternative.

Lactoperoxidase (LPO) belongs to mammalian heme peroxidase superfamily which also includes myeloperoxidase (MPO), eosinophil peroxidase (EPO) and thyroid peroxidase (TPO). LPO catalyzes the oxidation of a number of substrates including thiocyanate while TPO catatalyzes the biosynthesis of thyroid hormones. LPO is also been shown to catalyze the biosynthesis of thyroid hormones indicating similar functional and structural properties. The binding studies showed that 2-mercaptoimidazole (MZY) bound to LPO with a dissociation constant of 0...

The zebrafish thyroid gland shows a unique pattern of growth. Despite the lack of a compact gland, the zebrafish thyroid tissue originates from the pharyngeal endoderm and the main genes involved in its patterning and early development are conserved between zebrafish and mammals. In recent years, the research has been focused to the search of novel candidate genes and environmental factors underlying congenital hypothyroidism. Among these, it has been demonstrated that the Notch signalling plays a central role during zebrafish thyroid development...

Thyroid hormones (THs) are essential for the correct development of nearly every structure in the body from the very early stages of development, yet the embryonic thyroid gland is not functional at these stages. To clarify the roles of the egg yolk as a source of THs, the TH content in the yolk and the expression of TH regulator genes in the yolk sac membrane were evaluated throughout the 21-day incubation period of chicken embryos. The yolk TH content (22.3 ng triiodothyronine and 654.7 ng thyroxine per total yolk on day 4 of incubation) decreased almost linearly along with development...

Infantile hepatic hemangioendothelioma (IHHE) is the most common benign vascular liver tumor and typically occurs during the first 6 months of life. A 4-month-old male patient presented with abdominal distention. A physical examination revealed massive hepatomegaly. Liver enzyme levels were normal. The alpha fetoprotein level was 1,323 mg/dL (6-1,000). Abdominal magnetic resonance imaging (MRI) showed multiple, well-defined and hyperintense nodular lesions in the liver. MRI findings suggested IHHE. The thyroid stimulating hormone (TSH) level was high (177...

Here we describe a conditional doxycycline-dependent mouse model of RET/PTC3 (NCOA4-RET) oncogene-induced thyroid tumorigenesis. In these mice, after 10 days of doxycycline (dox) administration, RET/PTC3 expression induced mitogen activated protein kinase (MAPK) stimulation and a proliferative response which resulted in the formation of hyperplastic thyroid lesions. This was followed, after 2 months, by growth arrest accompanied by typical features of oncogene-induced senescence (OIS), including upregulation of p16INK4A and p21CIP, positivity at the Sudan black B, activation of the DNA damage response (DDR) markers γH2AX and pChk2 T68, and induction of p53 and p19ARF...

OBJECTIVES: Although decreased thyroid function is negatively correlated with clinical outcomes in critically ill patients, its role in allogeneic haematopoietic cell transplantation (allo-HCT) has not been sufficiently described. METHODS: The associations between pre-conditioning thyroid hormone concentrations and transplant-related complications in 474 adult patients with haematologic malignancies who underwent myeloablative allo-HCT were assessed. RESULTS: A receiver-operating characteristic curve showed that the baseline serum-free triiodothyronine 3 (FT3) level had an excellent predictive value for non-relapse mortality (NRM) within 100 days in sibling HCT with an area under the curve of 0...

Epidemiological studies have shown that thyroid hormone balances can be disrupted by chemical exposure. However, many association studies have often failed to consider multiple chemicals with possible common sources of exposure, rendering their conclusions less reliable. In the 2007-2008 National Health and Nutrition Examination Survey (NHANES) from the U.S.A., urinary levels of environmental phenols, parabens, and phthalate metabolites as well as serum thyroid hormones were measured in a general U.S. population (≥12years old, n=1829)...
