Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

6.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Redox Titration: Iodimetry and Iodometry01:23

Redox Titration: Iodimetry and Iodometry

4.0K
Iodometry and iodimetry are analytical methods used to determine the concentration of oxidizing or reducing agents using iodine. In iodometric titrations, the oxidizing analyte solution is usually acidified and treated with an excess of iodide ions, which generates an equivalent amount of iodine in equilibrium with triiodide. The released iodine is subsequently titrated directly against a standardized reducing agent. As the dilute iodine color becomes pale yellow, a few drops of freshly...

The Thyroid Gland01:23

The Thyroid Gland

5.5K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

4.1K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Radiological Investigation I: X-ray and CT

741
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

501
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Summary
This summary is machine-generated.

Iodine deficiency is decreasing globally. Current evidence does not support widespread iodine supplementation for pregnant women, infants, or young children, even in mildly deficient areas.

Area of Science:

  • Nutritional Science
  • Public Health
  • Pediatrics

Background:

  • Iodine deficiency remains a public health concern, though global rates have declined significantly since 1993.
  • Severe iodine deficiency during pregnancy is linked to impaired cognitive development in offspring.
  • The impact of mild-to-moderate iodine deficiency on neurodevelopment is debated.

Purpose of the Study:

  • To review current data on iodine deficiency.
  • To assess the health impacts of iodine deficiency.
  • To evaluate the necessity of iodine supplementation in at-risk populations.

Main Methods:

  • Review of recent data on iodine deficiency.
  • Analysis of systematic reviews on iodine supplementation efficacy.
  • Examination of health outcomes related to iodine status.

Main Results:

  • Global iodine deficiency has decreased substantially, with only 23 countries reporting insufficient intake in 2019.
  • Systematic reviews found no evidence that iodine supplementation improves cognitive development in children in mildly deficient areas.
  • No evidence supports iodine supplementation for preterm infants regarding morbidity or mortality.

Conclusions:

  • There is no scientific basis for generalized iodine supplementation in populations with mild-to-moderate iodine deficiency.
  • Supplementation is not recommended for pregnant women, lactating women, infants, or young children in these settings.
  • Focus should remain on addressing severe iodine deficiency where identified.
