Bone Disorders01:29

Bone Disorders

4.1K
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...

The Parathyroid Glands00:59

The Parathyroid Glands

2.8K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Hormones and Bone Tissue01:17

Hormones and Bone Tissue

3.1K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Bone Remodeling01:40

Bone Remodeling

38.7K
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.

Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

3.4K
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...

Skeleton and Calcium Homeostasis01:21

Skeleton and Calcium Homeostasis

5.0K
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.

Summary

Parathyroidectomy surgery significantly improved frailty scores in patients, as measured by the Risk Analysis Index. This suggests that parathyroid surgery may help slow the progression of frailty.

Area of Science:

  • Endocrinology
  • Geriatrics
  • Surgical Research

Background:

  • Frailty assessment tools can identify symptoms overlapping with primary hyperparathyroidism.
  • Surgical interventions for endocrine disorders may impact patient frailty.

Purpose of the Study:

  • To investigate the effect of parathyroidectomy on frailty.
  • To compare frailty changes after parathyroid surgery versus thyroid surgery.

Main Methods:

  • Prospective cohort study comparing patients undergoing parathyroid exploration or total thyroidectomy.
  • Longitudinal assessment of the Risk Analysis Index (RAI) for frailty preoperatively, postoperatively, and at follow-up.

Main Results:

  • Parathyroid exploration patients (n=187) had higher baseline RAI scores than thyroidectomy patients (n=142).
  • RAI scores significantly decreased post-parathyroidectomy but not post-thyroidectomy.
  • Parathyroidectomy patients were less likely to experience a clinically significant increase in frailty over time.

Conclusions:

  • Parathyroid exploration surgery is associated with a decrease in frailty as measured by the RAI.
  • Compared to thyroidectomy, parathyroidectomy may preserve or improve frailty status post-surgery.
