Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
Bone Disorders01:29

Bone Disorders

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...
Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

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...
Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
Nursing Assessment01:29

Nursing Assessment

The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments and...

Summary

Nurses possess moderate knowledge regarding osteoporosis prevention and treatment, despite feeling confident in their role. Targeted education is recommended to enhance their understanding of the disease, its risk factors, and management strategies.

Area of Science:

  • Nursing Research
  • Bone Health
  • Disease Prevention

Background:

  • Healthcare professionals require comprehensive disease knowledge for effective prevention and treatment strategies.
  • Existing knowledge gaps concerning osteoporosis prevention and management have been identified among global healthcare professionals, including nurses.

Purpose of the Study:

  • To evaluate nurses' knowledge and attitudes towards osteoporosis.
  • To assess a broad spectrum of factors related to nurses' understanding and perspectives on osteoporosis.

Main Methods:

  • A cross-sectional study design was employed.
  • Data were collected from 158 registered nurses at two academic centers in northern Israel using self-administered surveys.
  • The Facts on Osteoporosis Quiz (FOOQ) was utilized to assess objective knowledge.

Main Results:

  • Nurses expressed confidence in their role and skills for osteoporosis management.
  • Objective knowledge regarding osteoporosis risk factors was moderate, with an average FOOQ score of 17 out of 24.
  • Higher scores were observed among female nurses, those in Health Maintenance Organizations (HMOs), and those who had undergone bone density measurement.

Conclusions:

  • Nurses acknowledge their crucial role in public education on osteoporosis prevention and management.
  • Knowledge concerning disease signs, medication, and lifestyle factors was moderate.
  • Nurses reported confidence primarily in fall prevention advice.
  • Educational initiatives and postgraduate courses are recommended to improve nurses' osteoporosis knowledge.
