Changes in the Appendicular Skeleton with Age

3.7K
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

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...

Mechanistic Models: Compartment Models in Individual and Population Analysis

Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Summary

Sarcopenia affects 11% of Mexican older adults. This study used tailored measurements to assess sarcopenia prevalence and severity, finding it increases with age and may benefit from targeted interventions.

Area of Science:

  • Gerontology
  • Public Health
  • Epidemiology

Background:

  • Sarcopenia, age-related muscle loss, is a growing concern in aging populations worldwide.
  • Accurate prevalence data is crucial for developing effective public health strategies.
  • Previous sarcopenia assessments in Mexico may not have used culturally relevant diagnostic criteria.

Purpose of the Study:

  • To determine the prevalence of sarcopenia in Mexican older adults.
  • To adapt and apply the European Working Group on Sarcopenia in Older People (EWGSOP) algorithm using tailored cutoff values.
  • To investigate the relationship between age and sarcopenia severity in this population.

Main Methods:

  • Utilized cross-sectional data from the third wave (2012) of the Mexican Health and Aging Study.
  • Estimated muscle mass using a formula based on anthropometry and demographics.
  • Adapted gait speed and handgrip strength cutoff values specifically for Mexican older adults.

Main Results:

  • Sarcopenia was identified in 11% (n=137) of the 1,238 participants.
  • Pre-sarcopenia was observed in 39.1% (n=484), moderate sarcopenia in 8.3% (n=103), and severe sarcopenia in 2.75% (n=34).
  • The prevalence and severity of sarcopenia increased with advancing age.

Conclusions:

  • Sarcopenia is a significant health issue among Mexican older adults.
  • Tailored diagnostic criteria are essential for accurate sarcopenia identification in diverse populations.
  • Early identification and intervention strategies tailored to sarcopenia severity are recommended.
