To date only a fraction of the genetic footprint of thyroid function has been clarified. We report a genome-wide association study meta-analysis of thyroid function in up to 271,040 individuals of European ancestry, including reference range thyrotropin (TSH), free thyroxine (FT4), free and total triiodothyronine (T3), proxies for metabolism (T3/FT4 ratio) as well as dichotomized high and low TSH levels. We revealed 259 independent significant associations for TSH (61% novel), 85 for FT4 (67% novel), and 62 novel signals for the T3 related traits. The loci explained 14.1%, 6.0%, 9.5% and 1.1% of the total variation in TSH, FT4, total T3 and free T3 concentrations, respectively. Genetic correlations indicate that TSH associated loci reflect the thyroid function determined by free T3, whereas the FT4 associations represent the thyroid hormone metabolism. Polygenic risk score and Mendelian randomization analyses showed the effects of genetically determined variation in thyroid function on various clinical outcomes, including cardiovascular risk factors and diseases, autoimmune diseases, and cancer. In conclusion, our results improve the understanding of thyroid hormone physiology and highlight the pleiotropic effects of thyroid function on various diseases.

Myoepithelial carcinoma (MECA) is a malignant neoplasm composed exclusively of myoepithelial cells and accounts for less than 1% of all salivary gland tumors. Its diagnosis is often challenging due to histologic overlaps with benign lesions and its variable morphologic presentation. Although molecular profiling has emerged as a valuable tool in salivary gland tumor classification, the genetic landscape of MECA remains incompletely defined.

Objective: This study presents a comparative analysis of outcomes of lateral orbital wall decompression performed using ultrasonic bone removal with standard and modified techniques.
Material And Methods: The study included 78 patients (109 orbits) with exophthalmos without visual impairment (subgroups 1A and 1B) and with optic neuropathy (ON) due to thyroid eye disease (TED) (subgroups 2A and 2B). Lateral wall decompression (LWD) was performed using ultrasonic bone removal with a modified (=58, patient subgroups 1A and 2A) or standard (=51, subgroups 1B and 2B) technique.

Purpose: To assess the utility of inflammatory marker levels in defining orbital cellulitis (OC) severity.
Methods: A retrospective cohort study was conducted at 2 tertiary care centers using a medical record search of billing codes from January 1, 2000, to January 1, 2023. Patients were categorized into 2 cohorts-uncomplicated OC and OC with complication [subperiosteal abscess (SPA), orbital abscess (OA), or cavernous sinus thrombosis (CST)].

Thyroid cancer, a prevalent endocrine malignancy, is influenced by its tumor microenvironment (TME), with cancer-associated fibroblasts (CAFs) playing a pivotal role in disease progression. Molecularly, CAFs orchestrate a pro-tumorigenic niche via cytokine secretion and extracellular matrix (ECM) stiffening, underscoring their targetability. Therapeutic strategies, including small molecule inhibitor-based therapies, immune-based therapies, nanoparticle-based approaches, and combination regimens, have been evaluated for their efficacy in disrupting CAF functionality.

Psoriasis is an inflammatory dermatological condition challenging to treat and prone to recurrence. The pathogenesis of psoriasis is closely associated with metabolic disorders, while therapies targeting the dysregulated metabolism in psoriasis remain limited. Therefore, exploring the pathogenesis of psoriasis and identifying potential metabolic therapeutic targets is imperative.
