The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.0K
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...

Drug Dosing: Geriatric Patients

325
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

282
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 Excretion

287
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 Distribution

299
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...

Bone Disorders01:29

Bone Disorders

5.7K
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...

Area of Science:

  • Gerontology
  • Public Health
  • Clinical Medicine

Background:

  • Frailty is a state of decreased homeostatic reserves, leading to vulnerability.
  • This vulnerability increases the risk of adverse health outcomes.
  • Current healthcare systems struggle to address the needs of aging populations.

Purpose of the Study:

  • To highlight frailty as a critical public health issue.
  • To advocate for healthcare system reform to better manage frailty.

Main Methods:

  • Literature review on frailty definitions and implications.
  • Analysis of the impact of frailty on health outcomes.
  • Assessment of current healthcare system capacity for aging populations.

Main Results:

  • Frailty is a significant predictor of negative health outcomes.
  • Multiple definitions exist, lacking a universal gold standard.
  • Existing healthcare models are inadequate for the aging demographic.

Conclusions:

  • Frailty requires recognition as a major public health concern.
  • Healthcare systems must adapt to effectively manage frailty in aging individuals.
  • Reshaping healthcare is essential to meet the needs of the elderly.
