Summary
Nutritional rickets in children stems from vitamin D deficiency or low calcium. Supplementing vitamin D for breastfed infants is crucial to prevent bone deformities and reduce rickets incidence.
Area of Science:
- Pediatrics
- Nutrition
- Bone Metabolism
Background:
- Nutritional rickets is a bone formation disorder in children.
- It is primarily caused by vitamin D deficiency, low calcium intake, or both.
- Prolonged breastfeeding without vitamin D supplementation is a significant risk factor in the United States.
Purpose of the Study:
- To highlight the importance of vitamin D supplementation for breastfed infants.
- To reduce the incidence of vitamin D deficiency rickets.
- To prevent bone deformities in children.
Main Methods:
- This study is a review of current literature and clinical guidelines.
- It focuses on the etiological factors and preventative strategies for nutritional rickets.
- Analysis of risk factors associated with infant feeding practices.
Main Results:
- Vitamin D deficiency is a primary cause of nutritional rickets.
- Breastfeeding without adequate vitamin D intake increases risk.
- Supplementation is a key preventative measure.
Conclusions:
- Increased awareness regarding vitamin D supplementation is essential.
- Universal vitamin D supplementation for breastfed infants can decrease rickets prevalence.
- Proactive supplementation prevents long-term bone health issues.

01:23Role of Skin in Vitamin D Synthesis
5.2K
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...

01:25Role of Vitamins in Maintaining Bone Health
3.4K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

745
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...

01:29Bone Disorders
3.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

10.3K
In humans, electrolytes play a vital role in various physiological processes. Balancing electrolyte levels is essential for normal body functions; their imbalance can be life-threatening. The major electrolytes include sodium, potassium, chloride, calcium, phosphate, and bicarbonate. They are primarily involved in physiological processes, such as nerve signal transmission, membrane trafficking, muscle contraction, buffering body fluids, and balancing water levels in the body.

01:21Skeleton and Calcium Homeostasis
4.6K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.
