Effect of Fasting Status on Association between Exposure to Phthalate and Phenolics, and Thyroid Hormones in Adult Women of Reproductive Age.

Diet is one of the important exposure sources for many urinary chemicals that have been investigated in association studies for thyroid hormone outcomes. For these chemicals, the fasting status of the study population can substantially affect the results of urinary biomonitoring. Such variability presents challenges for cross-sectional association studies, particularly when the substances of concern have short excretion half-lives.

Department of Clinical Medicine and Surgery, University of Naples "Federico II", 80131, Naples, Italy.
Purpose: Type 2 deiodinase (D2), encoded by DIO2 gene, catalyzes the activation of the prohormone thyroxine (T4) into the bioactive hormone triiodothyronine (T3) in peripheral tissues, thereby regulating the intracellular Thyroid Hormone (TH) availability. Recently, several studies have demonstrated that a drastic increase in the peripheral activation of TH, via D2, fosters tumor progression, metastasis, and immunity.
Methods: To further prove the clinical relevance of D2 in human cancer, based on public Database of The Cancer Genome Atlas (TCGA), we conducted a pan-cancer analysis of DIO2 expression in various cancer types and investigated the association of DIO2 expression with the tumor microenvironment (TME) components and immune cell infiltration, along with the DIO2 genetic alteration types.
Sciatic nerve analysis in thyroid hormone transporter Mct8 and Oatp1c1 knockout mice.

H Heuer, Department of Endocrinology, Diabetes and Metabolism, University of Duisburg-Essen, Essen, Germany.
Objective: Mutations in the thyroid hormone (TH) transporter monocarboxylate transporter 8 (MCT8) cause Allan-Herndon-Dudley syndrome (AHDS), a severe form of psychomotor retardation with muscle hypoplasia and spastic paraplegia as key symptoms. These abnormalities have been attributed to an impaired TH transport across brain barriers and into neural cells thereby affecting brain development and function. Likewise, Mct8/Oatp1c1 (organic anion transporting polypeptide 1c1) double knockout (M/Odko) mice, a well-established murine AHDS model, display a strongly reduced TH passage into the brain as well as locomotor abnormalities.

Endocrine
January 2025
Department of General Surgery, Tianjin Medical University General Hospital, Tianjin, China.
Purpose: To evaluate the diagnostic value of different subtypes of non-punctate echogenic foci in thyroid malignancy.
Methods: Retrospective research of 342 thyroid nodules with calcification was performed. The echogenic foci were divided into punctate echogenic foci (type I) and non-punctate echogenic foci (type II), and type II were further divided into four subtypes: macrocalcification (type IIa), continuous peripheral calcification (type IIb), discontinuous peripheral calcification (type IIc) and isolated calcification (type IId).
Distributive and Refractory Shock in Myxoedema Coma.
Cureus
December 2024
Intensive Care Unit, Hospital de Braga, Braga, PRT.
Myxoedema coma is a rare medical emergency, presenting even less commonly without sepsis and with the diagnosis of distributive shock. Reports of catecholamine-refractory shock are scarce. This report describes the case of a 54-year-old male, who presented to the emergency department with altered mental status.
