Vitamins

2.5K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Nerve Supply of the GI Tract01:27

Nerve Supply of the GI Tract

3.7K
The neuronal supply to the gastrointestinal (GI) tract is essential for regulating various functions, including digestion, absorption, and movement of food. This intricate network of nerves is known as the enteric nervous system (ENS), often referred to as the "second brain" of the body.
The enteric nervous system consists of two major plexuses: the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). These plexuses are located within the layers of...

Blood Supply to the Digestive System01:16

Blood Supply to the Digestive System

5.5K
Splanchnic circulation refers to the network of blood vessels that supply and drain blood from the abdominal organs involved in digestion, including the stomach, liver, pancreas, intestines, and spleen. This circulation delivers essential nutrients and oxygen while removing waste products from these organs.
Blood Supply to the Digestive System: The splanchnic circulation involves three main arteries: the celiac artery (also known as the celiac trunk) and the superior and inferior mesenteric...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

8.0K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Mineral, Vitamin and Water Absorption01:27

Mineral, Vitamin and Water Absorption

1.6K
Electrolytes are essential minerals and ions primarily obtained from the diet and absorbed through the gastrointestinal tract. Most electrolytes are absorbed in the small intestine. While the absorption of iron and calcium primarily occurs in the duodenum, calcium is also absorbed in the jejunum and ileum. In these regions, passive diffusion contributes to its absorption alongside active transport mechanisms in the duodenum. These ions can exit the enterocytes through specialized active...

Energy Supply for Muscle Contraction01:25

Energy Supply for Muscle Contraction

5.7K
Skeletal muscle fibers have the unique ability to switch between rest and contraction states, using different sources of ATP for energy. The contraction cycle and Ca2+ transport back into the sarcoplasmic reticulum for relaxation require significant ATP. However, the ATP reserves in muscle fibers are limited and can only sustain contractions for a few seconds. Additional ATP production becomes necessary for prolonged contractions. As a result, muscle fibers generate ATP through various sources,...

Summary

Low vitamin D levels are common in female healthcare workers, especially in winter and spring or with obesity. Ensuring adequate vitamin D is crucial to prevent health issues.

Area of Science:

  • Nutritional biochemistry
  • Occupational health

Background:

  • Vitamin D deficiency is a growing public health concern.
  • Healthcare workers may face unique occupational exposures impacting vitamin D status.

Purpose of the Study:

  • To investigate the determinants of serum vitamin D levels in female healthcare workers.
  • To assess the prevalence of vitamin D insufficiency in this population.

Main Methods:

  • Cross-sectional study of 67 female healthcare workers (aged 25-60 years).
  • Analysis of serum vitamin D levels in relation to age, BMI, physical activity, and shift work.
  • Seasonal variation in vitamin D levels was examined.

Main Results:

  • Overall vitamin D levels were low (median: 20 ng/mL), with a wide range (6-51 ng/mL).
  • Lower serum vitamin D was observed during winter and spring.
  • Obesity (high BMI) was associated with lower vitamin D levels.
  • Shift work showed minimal impact on vitamin D status.

Conclusions:

  • A high prevalence of vitamin D undersupply exists among female healthcare workers.
  • Seasonal factors (winter/spring) and obesity significantly impact vitamin D status.
  • Interventions to ensure adequate vitamin D supply, particularly during winter and spring, are recommended to mitigate potential health risks.
