Changes in the Appendicular Skeleton with Age01:09

Changes in the Appendicular Skeleton with Age

3.0K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Bone Disorders

4.4K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

33
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...

Pharmacodynamics in Geriatric Patients: Effects of Age

53
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Signs of Puberty

805
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

2.9K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Summary

This study found that impaired lower extremity function, indicated by slower gait speed and longer Timed Up and Go Test times, is linked to hyperkyphosis in older adults. This suggests a connection between sarcopenia and age-related spinal curvature.

Area of Science:

  • Gerontology
  • Orthopedics
  • Physical Therapy

Background:

  • Age-related hyperkyphosis is a common disability in the elderly.
  • Loss of muscle mass and function (sarcopenia) is suspected to contribute to hyperkyphosis.

Purpose of the Study:

  • To investigate the relationship between sarcopenia and hyperkyphosis in elderly patients.
  • To identify if lower extremity muscle function is associated with age-related hyperkyphosis.

Main Methods:

  • A cross-sectional study of 142 elderly patients (mean age 72) comparing hyperkyphotic and non-hyperkyphotic groups.
  • Sarcopenia diagnosed using EWGSOP 2 criteria, including SARC-F, handgrip strength, and bioimpedance analysis.
  • Gait speed, Timed Up and Go Test (TUG), and Tinetti Test assessed lower extremity function; hyperkyphosis measured by the bloc method.

Main Results:

  • Hyperkyphosis was significantly associated with poorer performance on the 4-m gait speed test (p=0.018) and TUG (p=0.042).
  • A gait speed cut-off of 0.65 m/s predicted hyperkyphosis with 60% sensitivity and 70% specificity.
  • Tinetti balance and gait scores were negatively correlated with hyperkyphosis (p=0.006 to p=0.031).

Conclusions:

  • Lower extremity muscle function is related to age-related hyperkyphosis, differing from previously suggested factors.
  • Further research into hyperkyphosis prognosis in severe sarcopenic individuals is warranted.
  • This study highlights a potential link between sarcopenia and hyperkyphosis, suggesting new avenues for research and intervention.
