Pharmacodynamics in Geriatric Patients: Effects of Age01:27

Pharmacodynamics in Geriatric Patients: Effects of Age

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...
Hearing01:31

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
Perception of Sound Waves01:01

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...

Drug Dosing: Geriatric Patients

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 Absorption01:22

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

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

Hearing loss affects 11.2% of elderly individuals in São Paulo, Brazil, with men experiencing higher prevalence. Many older adults lack knowledge about hearing loss causes and its impact on daily life.

Area of Science:

  • Gerontology
  • Public Health
  • Epidemiology

Context:

  • The aging population in São Paulo, Brazil, presents unique public health challenges.
  • Understanding the prevalence and factors associated with hearing loss in the elderly is crucial for targeted interventions.

Purpose:

  • To estimate the prevalence of self-reported hearing loss among elderly residents of São Paulo.
  • To identify socio-demographic factors associated with hearing loss in this population.
  • To assess the impact of hearing loss on daily activities and knowledge of causes.

Summary:

  • A cross-sectional study analyzed data from 872 elderly participants in the São Paulo Health Survey (ISA-Capital 2003).
  • Prevalence of self-reported hearing loss was 11.2%, significantly higher in men (Prevalence Ratio = 1.86).
  • 42.5% of participants lacked knowledge about hearing loss causes, and 25.5% reported difficulties in leisure activities.

Impact:

  • The findings underscore hearing loss as a significant public health issue among the elderly in urban Brazil.
  • Results highlight the need for increased awareness and targeted public health strategies to address hearing impairment in aging populations.
  • This research informs healthcare professionals and policymakers about the growing demands associated with an aging demographic and sensory decline.
