Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

5.2K
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...

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

3.2K
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...

Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

842
Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Temperature Measurement Sites01:14

Temperature Measurement Sites

2.2K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Body Temperature01:07

Body Temperature

528
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Summary

Extremely low ambient temperatures significantly impact thyroid function, increasing levels of free triiodothyronine (FT3) and free thyroxine (FT4). Cold weather protective measures are advised, especially for individuals with thyroid disorders.

Area of Science:

  • Environmental Health
  • Endocrinology
  • Epidemiology

Background:

  • Seasonal influences on thyroid function are known, but the specific effects of extreme cold and temperature lags are not well understood.
  • Investigating non-linear and lagged temperature effects is crucial for public health during cold spells.

Purpose of the Study:

  • To analyze the non-linear and lagged associations between extremely low ambient temperatures and thyroid function parameters.
  • To identify specific thyroid hormone changes in response to cold exposure.

Main Methods:

  • A panel study design utilizing data from 1237 individuals in Altay City, China (2020-2023).
  • Mixed-effects modeling with distributed lagged non-linear models (DLNMs) was employed to analyze five thyroid function parameters.
  • Analysis included comparisons to a benchmark temperature of 8.5°C.

Main Results:

  • At -20°C, significant increases were observed in free triiodothyronine (FT3) and free thyroxine (FT4) compared to the benchmark temperature.
  • Elevated temperatures (20°C to 29°C) correlated with increased total thyroxine (TT4) and decreased FT4.
  • Subgroup analyses revealed greater TT4 increases in women and more pronounced increases in TT4, FT4, and FT3 among individuals with pre-existing thyroid disorders.

Conclusions:

  • Extremely low ambient temperatures demonstrably affect thyroid function, altering key hormone levels.
  • Implementing protective measures during cold weather is recommended to maintain thyroid stability.
  • Vulnerable populations, particularly those with thyroid disorders, may require enhanced precautions against cold exposure.
