Aging

479
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Pharmacodynamics in Geriatric Patients: Effects of Age

111
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...

Drug Dosing: Geriatric Patients

129
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Metabolism

110
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

95
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...

Continuing Care01:25

Continuing Care

1.7K
Continuing care describes the variety of health, personal, and social services provided over a prolonged period. The need for continuing care is increasing because people are living longer. Many people do not have families or others to care for them. Continuing care is mainly for patients who are disabled, functionally dependent, or suffering from a terminal disease. It is available within institutional settings or in homes. Examples include nursing centers or facilities, assisted living,...

Area of Science:

  • Geriatric Medicine
  • Public Health
  • Demography

Background:

  • Developed nations face population aging, increasing demand on health services.
  • Israel's older population is aging rapidly, straining community, acute, rehabilitation, and long-term care.
  • Geriatric medicine is crucial for high-quality care of the elderly.

Purpose of the Study:

  • To highlight the importance of geriatric medicine in addressing age-related health challenges.
  • To provide an overview of topics relevant to Israeli geriatric researchers.
  • To emphasize the role of geriatricians in managing the "Geriatric Giants".

Main Methods:

  • Review of current knowledge and understanding of aging and age-related diseases.
  • Emphasis on a multidisciplinary, function-based approach to assessment and treatment.
  • Overview of topics and studies of interest to Israeli researchers in geriatric medicine.

Main Results:

  • Recognition of "Geriatric Giants" (immobility, falls, incontinence, cognitive impairment, iatrogenesis) has led to improved diagnosis and treatment.
  • Geriatricians play a central role in healthcare for older people.
  • A multidisciplinary approach enhances assessment and treatment effectiveness.

Conclusions:

  • Geriatric medicine is essential for managing the complexities of an aging population.
  • Understanding and addressing "Geriatric Giants" improves patient outcomes.
