Bone Disorders01:29

Bone Disorders

5.0K
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...

Drug Dosing: Geriatric Patients

158
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Pharmacodynamics in Geriatric Patients: Effects of Age

134
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

125
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

176
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

131
Geriatric patients show significant variation in how their bodies process medications, which can change how effective and safe treatments are. The liver is the primary organ where drug metabolism occurs, involving two main types of chemical reactions: phase I and II. Phase I metabolism is driven by the cytochrome P450 enzyme system, which includes key types such as CYP3A, CYP2D6, and CYP2C9. Research indicates that while aging doesn't notably alter the levels or activity of these enzymes, it...

Summary

Osteoporosis fractures are rising in the elderly. Comprehensive geriatric assessment, including fall risk and nutrition, is key for fracture prevention, alongside lifestyle changes and medication.

Area of Science:

  • Geriatrics
  • Orthopedics
  • Public Health

Background:

  • Osteoporotic fractures and their socioeconomic impact are increasing globally due to population aging.
  • In Germany, an estimated 750,000 fragility fractures occur annually, yet osteoporosis is often underdiagnosed and undertreated in the elderly.
  • Factors like frailty, sarcopenia, malnutrition, and falls contribute significantly to osteoporotic fractures in older adults.

Purpose of the Study:

  • To highlight the importance of comprehensive geriatric assessment alongside bone mineral density measurement for accurate fracture risk estimation in the elderly.
  • To emphasize the need for integrated fall and fracture prevention strategies tailored to the geriatric population.
  • To advocate for improved diagnosis and treatment of osteoporosis in older adults.

Main Methods:

  • Combining dual-energy X-ray absorptiometry (DXA) with problem-oriented geriatric assessments, evaluating muscle strength, walking speed, nutrition, fall risk, and cognitive function.
  • Recognizing age as a primary fracture risk factor in individuals over 70 (women) and 80 (men), potentially allowing omission of DXA in specific cases.
  • Implementing targeted training for strength, endurance, coordination, and balance, alongside lifestyle modifications and nutritional support (calcium/vitamin D).

Main Results:

  • A comprehensive geriatric assessment is crucial for estimating fracture risk in elderly patients.
  • Age alone is a dominant fracture risk factor in older women and men, influencing the necessity of DXA.
  • Effective fall and fracture prevention strategies involve physical training, healthy lifestyle, nutritional management, and pharmacotherapy.

Conclusions:

  • Integrated approaches combining bone density assessment, geriatric evaluation, and lifestyle interventions are essential for managing osteoporosis in the elderly.
  • Fracture liaison services show promise in reducing fracture risk within high-risk geriatric populations.
  • Early diagnosis, appropriate substitution of calcium and vitamin D, and timely initiation of anti-osteoporotic medications are vital for secondary fracture prevention.
