Background: Since 2010, three meta-analyses have been published on the impact of thyroid autoimmunity (TAI) on pregnancy outcomes in infertile women treated with assisted reproductive technology (ART). The initially observed high risk of miscarriage became very low in the most recent meta-analysis published in 2016. Objective: To investigate whether the lower risk of miscarriage in the latest meta-analysis was associated with the increased use of intracytoplasmic sperm injection (ICSI) in recent studies...

With population aging, prevalence of low bone mineral density (BMD) and associated fracture risk are increased. To determine whether low circulating thyroid stimulating hormone (TSH) levels within the normal range are causally related to BMD, we conducted a two-sample Mendelian randomization (MR) study. Furthermore, we tested whether common genetic variants in the TSH receptor (TSHR) gene and genetic variants influencing expression of TSHR (eQTLs) are associated with BMD. For both analyses, we used summary-level data of genome-wide association studies (GWAS) investigating BMD of the femoral neck (N = 32,735) and the lumbar spine (N = 28,498) in cohorts of European ancestry from the Genetic Factors of Osteoporosis (GEFOS) Consortium...

PURPOSE: Several articles have demonstrated the high diagnostic performance of somatostatin receptor positron emission tomography (PET) in patients with neuroendocrine tumours (NETs). On the other hand, only a few studies have evaluated the detection rate (DR) of this imaging method in recurrent medullary thyroid carcinoma (MTC). We aimed to perform a systematic review and a meta-analysis of the DR of somatostatin receptor PET or PET/CT in patients with recurrent MTC to add evidence-based data to this setting...

Background: Recently, immune-checkpoint blockade has shown striking clinical results in different cancer patients. However, a significant inter-individual and inter-tumor variability exists among different cancers. The expression of the toxins granzyme A (GZMA) and perforin 1 (PRF1), secreted by effector cytotoxic T cells and natural killer (NK) cells, were recently used as a denominator of the intratumoral immune cytolytic activity (CYT). These levels are significantly elevated upon CD8+ T-cell activation as well as during a productive clinical response against immune-checkpoint blockade therapies...

BACKGROUND: Central neck dissection and total thyroidectomy are standard treatments for patients with papillary thyroid carcinoma (PTC) with clinically involved central nodes. However, prophylactic central neck dissection (pCND) in patients with clinically uninvolved cN0 has been beneficial in some studies but ineffective in others. We conducted a meta-analysis to evaluate the efficacy and safety of pCND in patients with central neck lymph nodes cN0 PTC. METHODS: The PubMed, EMBASE, Cochrane Library, and Scopus databases and the ClinicalTrials...

OBJECTIVE: Thyroid cancer (TC) is the most common malignant endocrine-related cancer with an increasing trend worldwide. Therefore, it's in urgent need to find new markers for prognosis and diagnosis. Many long noncoding RNAs (lncRNAs) have been reported to be aberrantly expressed in TC, and may serve as biomarkers. Therefore, we performed this meta-analysis to systematically summarize the relationship between lncRNA expressions and TC. METHODS: Sources from PubMed, Embase and Web of Science were searched...

BACKGROUND AND OBJECTIVE: Two tumor foci are the most common in multifocal papillary thyroid carcinoma, but whether they should be regarded as the indicator of central lymph node metastasis remains unclear. To investigate the role of two tumor foci for predicting central lymph node metastasis, we performed a meta-analysis of published studies. METHODS: We performed a systematic literature search of PubMed, Embase and Web of Science prior to September 29, 2017. The relevant articles were examined and the eligible studies were included to assess the metastatic risk of central lymph node in papillary thyroid carcinoma with one, two and more than two (>2) tumor foci...

The introduction of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was initiated and promoted by pathologists. Recent Asian studies added new knowledge to the existing literature to aid a better understanding of NIFTP. Our original data and the results of a meta-analysis suggest that the initial rate of NIFTP has been overestimated, averaging 9.1% (95% confidence interval [CI] 6.0-12.7%) of all papillary thyroid cancers worldwide. The incidence of NIFTP in the Asian population (1...

BACKGROUND: Evidence has shown that PD-L1 overexpression is associated with poor prognosis and resistance to immune therapies in several human cancers. However, data on the prognostic significance of PD-L1 expression in thyroid cancer is limited and remains controversial. In this systematic review and meta-analysis, we aimed to comprehensively evaluate the clinicopathological significance and prognostic value of PD-L1 expression in non-medullary thyroid cancers. SUMMARY: Electronic databases, including Medline/PubMed, EMBASE and the Cochrane Library, were searched up until July 5th, 2017...

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...

Thyroid cancer (TC) is the most common endocrine malignancy, with an incidence continuing to grow every year. Although thyroid cancer as a whole is generally indolent and relatively easy to treat, some subtypes carry a higher rate of metastasis and cancer-related mortality. A growing number of studies have focused on the dysregulation of miRNAs in TC. However, differences in methods make comparison of gene profiling data difficult. A meta-analysis of published studies comparing miRNA expression data of invasive thyroid carcinoma with paired non-invasive tumors or normal tissues was performed by searching the literature for "invasion", "thyroid cancer", and "miRNA"...

Background: In the last years, levothyroxine (LT4) has been commercialized also in liquid formulation, which is less sensitive to the factors known to reduce the absorption of tablet LT4. To date, there is no robust information that liquid LT4 can improve pharmacologic thyroid homeostasis of patients with reduced efficacy of tablet LT4. This analysis aimed at achieving solid evidence that switching thyroxine treatment from tablet to liquid preparation improves patients' TSH levels. Methods: The search was performed in PubMed/MEDLINE and Scopus database based on the terms "thyroid," "levothyroxine," and "liquid," and updated until September 25, 2017...
