Conservation of Small Populations02:04

Conservation of Small Populations

17.4K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Population Genetics?

64.8K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Population Growth

28.7K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Drug Dosing: Geriatric Patients

278
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

240
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...

Summary

Chronic pruritus in older adults is a growing concern due to skin barrier, immune, and nervous system issues. New treatments targeting specific itch pathways are emerging, offering hope for better management of this condition.

Area of Science:

  • Geriatric Medicine
  • Dermatology
  • Neuroscience

Background:

  • Chronic pruritus, defined as itching lasting over six weeks, significantly impacts the geriatric population (≥65 years old).
  • Pathophysiological factors include compromised epidermal barrier function, immune system dysregulation, and nervous system abnormalities.
  • Pruritus in the elderly can be classified into histaminergic and nonhistaminergic subtypes, influencing treatment strategies.

Purpose of the Study:

  • To review the current understanding of chronic pruritus in the geriatric population.
  • To discuss the underlying pathophysiological mechanisms and etiological factors.
  • To explore existing and emerging therapeutic options for geriatric pruritus.

Main Methods:

  • Literature review of studies on chronic pruritus in older adults.
  • Analysis of pathophysiological factors contributing to geriatric pruritus.
  • Evaluation of current treatment modalities, including topical and systemic approaches.

Main Results:

  • Abnormalities in the epidermal barrier, immune, and nervous systems are key predisposing factors.
  • Treatment decisions for systemic therapies consider the specific condition, comorbidities, and potential drug interactions.
  • Despite limited current options, significant progress in identifying itch-specific mediators is paving the way for novel therapies.

Conclusions:

  • Chronic pruritus in the elderly is a complex multifactorial condition requiring tailored management.
  • Topical treatments are generally safe, while systemic treatments necessitate careful consideration of patient-specific factors.
  • Advances in understanding itch mediators and ongoing clinical trials promise improved future treatments for geriatric pruritus.
