Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.9K
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 Disorders01:29

Bone Disorders

8.0K
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

5.1K
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...

Bone Remodeling01:40

Bone Remodeling

34.4K
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.

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

6.3K
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...

Fractures: Bone Repair01:27

Fractures: Bone Repair

5.9K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Area of Science:

  • Osteoporosis management
  • Physician education
  • Quality improvement in healthcare

Background:

  • Osteoporosis care quality varies among physicians.
  • Physicians need tools to assess and improve their practice.
  • Targeted interventions can enhance osteoporosis management.

Purpose of the Study:

  • To evaluate physician engagement in practice-based learning.
  • To assess the effectiveness of a self-evaluation module in improving osteoporosis care.
  • To identify factors influencing physician performance in osteoporosis management.

Main Methods:

  • Retrospective cohort study involving 850 U.S. physicians.
  • Utilized the American Board of Internal Medicine (ABIM) Osteoporosis Practice Improvement Module (PIM).
  • Measured performance on 23 process measures and 7 practice system domains before and after intervention.

Main Results:

  • Significant variability in performance across physician groups (internists, geriatricians, rheumatologists).
  • Patient-centered support and documentation of calcium/vitamin D were modestly associated with performance.
  • Physicians reported significant improvements in targeted osteoporosis care measures after using the PIM.

Conclusions:

  • Gaps in osteoporosis care quality persist.
  • Physicians can effectively use practice-based learning modules like the ABIM PIM to improve care.
  • The PIM facilitates actionable steps to enhance osteoporosis management.
