Purpose Of Review: Here we review typical thyroid function alterations observed in the critically ill pediatric patient.
Recent Findings: Abnormalities in the hypothalamic-pituitary-thyroid axis have recently been confirmed to be prevalent in similar proportions in pediatric and adult patients. Significant benefits of therapy have yet to be demonstrated.
Summary: At present, there is no evidence of benefit in giving thyroid hormone to patients with nonthyroidal illness who have low serum T3 or T4 concentrations, including preterm infants and postcardiac surgery patients.

Tamoxifen (TAM) is employed to treat premenopausal ER-positive breast cancer patients, but TAM resistance is the main reason affecting its efficacy. Thus, addressing TAM resistance is crucial for improving therapeutic outcomes. This study explored the potential role of Tinagl1, a secreted extracellular matrix protein, whose expression is compromised in TAM-resistant MCF-7 breast cancer cells (MCF-7R).

Anaplastic thyroid carcinoma is one of the highly fatal cancers and poses a serious threat to human health. Ferroptosis has been widely studied and proved to have an important role in tumor suppression, providing new avenues for cancer therapy; glutathione peroxidase 4(GPX4) and selenoprotein thioredoxin reductase(TXNRD1) are important regulatory targets in ferroptosis.Warburg effect is one of the important energy sources for cancer hypermetabolism, and pyruvate kinase isoenzyme 2 (PKM2) is a key metabolism enzyme that is important in this effect.

Iodine has an anti-proliferative effect on cancer cells; however, its effects have not been explored adequately. The aim of this study was to evaluate the therapeutic potential of iodine and radioiodine by assessing their effects on the viability of various breast cancer cell lines: MCF7, SKBR3, and MDA-MB231. The viability of cells was measured in treated cells exposed to six doses of iodine (5, 10, 20, 40, 60, 80 µM) and two doses of radioiodine (3.
