Background: Alcohol-induced changes in thyroid function may contribute to the development of mood disorders such as depression and anxiety that almost invariably coexist in alcohol-dependent individuals. The aim of the present study was to investigate the severity of liver dysfunction and thyroid activity in correlation with anxiety and depressive-like symptomatology before and after a detoxification period.
Patients And Methods: In a sample of 100 alcohol-abusing/dependent subjects treated on an in-patient basis according to a standard detoxification protocol, measurements of the serum levels of hepatic enzymes (ASAT, ALAT, gammaGT) and thyroid hormones (T3, T4, TSH) as well as measures of anxiety, depression and global functioning were obtained at baseline and at weekly intervals over the period of 4-5 weeks.
Results: After completion of the alcohol detoxification, most measurements returned to normal levels and correlations were observed between the levels of hepatic enzymes and thyroid hormones. Additionally, a significant correlation was obtained between the levels of thyroid hormones and the mood status scales.
Conclusion: Our results indicated a dysfunction of the hypothalamic-pituitary-thyroid axis in alcohol dependence with possible implications in the diagnosis and treatment of mood disorders associated with alcohol abuse.

Adequate levels of thyroid hormones (THs) in the fetal brain are vital for early neurodevelopment. Most of TH in fetal brain is derived from circulating thyroxine (T4), which gets locally converted into the biologically active triiodothyronine (T3) by deiodinase enzymes. One of the major routes of TH into the brain is through the blood-cerebrospinal fluid barrier (BCSFB).

Low free Tri-iodothyronine (FT₃) levels are generally associated with poor prognosis in patients with various critical illnesses. Acute ST-segment Elevation Myocardial Infarction (STEMI) represents the most lethal form of Acute Coronary Syndrome (ACS) with substantial short- and long-term mortality. This study was done to assess the association between FT₃ levels and in-hospital outcome of the STEMI patients treated with streptokinase therapy.

Hyperthyroidism is a common endocrine disease caused by the production of thyroid hormones in excessive amounts. Propylthiouracil (PTU) is one of the anti-thyroid drugs (ATD) used in the treatment of hyperthyroidism. Rectal PTU should be considered by physicians as a valuable option for managing hyperthyroidism as an alternative route of administration for patients who cannot tolerate oral medications.

Unlabelled: BACKGROUND AND RATIONALE: Thyroid dysfunction in older adults often mimics the signs of aging, impacting metabolism and overall physiological balance. While age-related chronic conditions have been extensively studied, the relationship between thyroid function and frailty remains underexplored.
Objective: This study aimed to evaluate the effects of thyroid dysfunction on frailty among individuals aged 65 years and older.

Background: Both iodine deficiency and iodine excess can harm the thyroid glands during pregnancy. In areas without iodine fortification, the relationship between the water iodine concentration (WIC) and thyroid disease in pregnant women requires further investigation.
Objective: The aim of this study was to evaluate the relationship between water iodine levels and the prevalence of thyroid disease in pregnant women residing in areas with high water iodine levels without access to iodized salt.
