Background: Graves' disease has been associated with adverse pregnancy, labor and delivery, and neonatal outcomes. Thyroid function levels, assessed during newborn screening (NBS), can serve as indicators of the adaptation in the hypothalamic-pituitary-thyroid axis. We utilized data from the national thyroid NBS program to investigate the characteristics of the mother-infant dyad of term infants born to mothers with past or active Graves' disease. Methods: The dataset of the Israeli NBS for thyroid function was linked with the electronic records of a tertiary medical center to generate a unified database of mothers and their term infants born between 2011 and 2021...

Background: Risk stratification systems for thyroid nodules are limited by low specificity. The fine-needle aspiration (FNA) biopsy size thresholds and stratification criteria are based on evidence from the literature and expert consensus. Our aims were to investigate the optimal FNA biopsy size thresholds in the American College of Radiology (ACR) Thyroid Imaging Reporting and Data System (TI-RADS) and artificial intelligence (AI) TI-RADS and to revise the stratification criteria in AI TI-RADS. Methods: A total of 2596 thyroid nodules (in 2511 patients) on ultrasound examination with definite pathological diagnoses were retrospectively identified from January 2017 to September 2021 in 6 participating Chinese hospitals...

Background: Nasolacrimal duct obstruction (NLDO) is an adverse effect of high dose radioactive iodine (RAI) therapy for thyroid carcinoma. There are currently no established preventive measures. This study assesses whether preservative free artificial tears (PFATs) can decrease the 131 I sodium iodide (131 I) activity in the tears of patients following RAI therapy for thyroid carcinoma, and potentially serve as a preventive measure for RAI-associated NLDO. Methods: This non-randomized prospective pilot clinical trial recruited contact-lens wearing patients undergoing RAI therapy for thyroid cancer to self-administer PFATs into the right eye for four days starting on the day of RAI ingestion...

Objective: Redifferentiation therapy (RDT) can restore radioactive iodine (RAI) uptake in differentiated thyroid cancer (DTC) cells to enable salvage 131 I therapy for previously RAI refractory (RAIR) disease. This study evaluated the clinical outcomes of patients who underwent RDT and identified clinicopathologic characteristics predictive of RAI restoration following RDT. Methods: This is a retrospective case series of 33 patients with response evaluation criteria in solid tumors (RECIST)-progressive metastatic RAIR-DTC who underwent RDT between 2017 and 2022 at the Mayo Clinic (Rochester, MN)...

Background: The impact of near-infrared autofluorescence (NIRAF) imaging on postthyroidectomy hypocalcemia is controversial. As patients with Graves' disease are at increased risk, our aim was to compare postoperative parathyroid function in these patients undergoing total thyroidectomy (TT) with or without NIRAF imaging. Methods: This was a retrospective "before and after" study, comparing outcomes of patients who underwent TT without or with NIRAF imaging at a single center. Primary outcome was the incidence of temporary hypocalcemia and secondary outcomes, rates of incidental parathyroidectomy on final specimens and permanent hypocalcemia...

Background: Total thyroidectomy (TT) and hemithyroidectomy (HT) are acceptable surgical options for the treatment of low-risk differentiated thyroid cancer (DTC). While previous data suggest similar disease-free and disease-specific survival regardless of initial surgical treatment, the effect of the extent of surgery on health-related quality of life (HRQOL) is less clear. This systematic review aimed to examine HRQOL in low-risk DTC survivors after TT compared with HT. Methods: A search of PubMed, CINAHL, Cochrane, PsycINFO, and Scopus databases was conducted to identify studies published between January 1, 2011, and December 31, 2022, that assessed HRQOL predominantly in patients with low-risk DTC who underwent open thyroid surgery...

Background: An accurate preoperative workup of cytologically indeterminate thyroid nodules (ITN) may rule out malignancy and avoid diagnostic surgery for benign nodules. This study assessed the performance of molecular diagnostics (MD) and 2-[18 F]fluoro-2-deoxy-d-glucose ([18 F]FDG)-positron emission tomography/computed tomography (PET/CT) in ITN, including their combined use, and explored whether molecular alterations drive the differences in [18 F]FDG uptake among benign nodules. Methods: Adult, euthyroid patients with a Bethesda III or IV thyroid nodule were prospectively included in this multicenter study...

Background Thyroid cancer cell lines have been of great value for the study of thyroid cancer. However, the availability of benign thyroid adenoma cell lines is limited. Methods Cell lines were established from thyroid adenomatous nodules that developed in mice treated with the goitrogen amitrole. Expression of epithelial, mesenchymal and thyroid markers of these established cell lines was determined and the effect of lentivirus-transduced overexpression of NKX2-1, a master regulator of thyroid development, on the thyroid marker expression was examined...

Background: ChatGPT, an artificial intelligence (AI) chatbot, is the fastest growing consumer application in history. Given recent trends identifying increasing patient use of Internet sources for self-education, we seek to evaluate the quality of ChatGPT-generated responses for patient education on thyroid nodules. Methods: ChatGPT was queried 4 times with 30 identical questions. Queries differed by initial chatbot prompting: no prompting, patient-friendly prompting, 8th-grade level prompting, and prompting for references...

Background: The limited availability of targeted therapies in thyroid cancer (TC) has challenged conventional treatment algorithms and has established urgency for the identification of targetable genomic abnormalities. In addition to widely adopted tissue-based next-generation sequencing (NGS), plasma-based circulating tumor DNA (ctDNA) NGS is rapidly emerging as a genomic biomarker detection method and is steadily gaining utility across solid tumors. To date, plasma-based genomic alterations in TC have not been determined...

OBJECTIVE: Rurality is associated with higher incidence and higher disease-specific mortality for most cancers. Outcomes for rural and ultra-rural ("frontier") patients with thyroid cancer are poorly understood. This study aimed to identify actionable deficits in thyroid cancer outcomes for rural patients. METHODS: We queried linked California Cancer Registry and California Office of Statewide Health Planning and Development databases for patients diagnosed with thyroid cancer (1999-2017)...

BACKGROUND: Tanycytes are specialized glial cells within the mediobasal hypothalamus that have multiple functions, including hormone sensing and regulation of hypophysiotropic hormone secretion. There are ongoing discussions about the role of tanycytes in regulating the supply of hypothalamic thyroid hormones (THs) through the expression of TH transporters ( Slc16a2 , Slco1c1 ) and deiodinases ( Dio2 , Dio3 ). In this study, we investigated the potential feedback effect of TSH on the transcription of these gatekeeper genes on tanycytes...

BACKGROUND: Anaplastic thyroid cancer (ATC) is highly aggressive and has very limited treatment options. Recent studies suggest that cancer stem cell (CSC) activity in ATC could underlie this recurrence and resistance to treatment. The recent approval by the U.S. Food and Drug Administration of the combined treatment of BRAF and MEK inhibitors for ATC patients has shown some efficacy in patients harboring the BRAFV600E mutation. However, it was unknown whether the combined treatment could affect the CSC activity...

Background: Although recent studies have introduced antibiotics as a potential risk factor for thyroid cancer, further studies are necessary. We examined the association between long-term antibiotic usage and thyroid cancer risk. Methods: This nationwide cohort study investigated 9,804,481 individuals aged 20 years or older who participated in health screening (2005-2006) with follow-up ending on December 31, 2019, using the Korean National Health Insurance Service database. Multivariable Cox proportional hazards regression was used to estimate adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for thyroid cancer risk according to the cumulative days of antibiotic prescription and the number of antibiotic classes, respectively...

BACKGROUND: Papillary thyroid cancer (PTC) is the predominant subtype of thyroid cancer, and it can cluster in families with an autosomal dominant (AD) inheritance pattern. Our aim was to identify novel genes and mechanisms underlying PTC susceptibility. METHODS: Our previous investigation of 17 AD PTC families led us to conduct a deeper analysis on one family (Family Q) with whole genome sequencing data from three PTC-affected individuals. Additionally, 323 sporadic thyroid cancer cases from Avatar data and 12 Familial adenomatous polyposis individuals with secondary thyroid cancer were screened for PDPR variants...

BACKGROUND: African American (AA) thyroid cancer patients have worse prognoses than European Americans (EA) which has been attributed to both healthcare disparities and possible genetic differences. We investigated the impact of both germline and somatic variants on clinical outcome in a cohort of AA non-medullary thyroid cancer (NMTC) patients who had received therapeutic intervention from cancer centers. METHODS: Whole exome sequencing was performed on DNA from available blood/normal tissues (N=37) and paired tumor samples (N=32) collected from 37 and 29 AA NMTC patients, respectively...

BACKGROUND: Glucagon-like peptide 1 (GLP-1) is involved in the regulation of energy and glucose homeostasis. As GLP-1 has similar effects on the energy homeostasis as the hypophysiotropic TRH neurons that regulate the hypothalamic-pituitary-thyroid (HPT) axis, we raised the possibility that the TRH neurons are involved in the mediation of the effects of GLP-1. Therefore, the relationship and interaction of the GLP-1 system and the TRH neurons of the hypothalamic paraventricular nucleus (PVN) were studied...
