The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.0K
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...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

41
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

4.6K
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

65
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...

Vitamins01:30

Vitamins

1.6K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Chronic Kidney Disease III: Interprofessional Care

168
Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Area of Science:

  • Gerontology
  • Nutritional Science
  • Public Health

Background:

  • Health and function preservation is crucial in an ageing society.
  • Ageing is a malleable process influenced by lifestyle factors, including diet.
  • Nutritional strategies are key to maintaining health and function in later life.

Purpose of the Study:

  • To review the importance of dietary patterns and nutritional concerns for older adults.
  • To identify key nutritional challenges and risks associated with ageing.
  • To inform tailored nutritional recommendations for the ageing population.

Main Methods:

  • Literature review on ageing, diet, and nutrition.
  • Analysis of evidence supporting healthful dietary patterns in later life.
  • Identification of specific nutrient concerns and physiological changes related to ageing.

Main Results:

  • Both dietary quality (healthy patterns) and quantity are vital for health maintenance and malnutrition risk in older adults.
  • Ageing affects nutrient physiology and metabolism, increasing risks for vitamin D, vitamin B12, and protein deficiencies.
  • Current dietary guidelines suggest a shift towards Mediterranean-style, plant-based diets.

Conclusions:

  • Tailored nutritional recommendations are needed for older adults, considering their unique physiological changes.
  • Further research is required to address limited evidence on older adults' nutritional needs, especially with shifts towards plant-based diets.
  • Integrating knowledge on ageing, nutrition, and dietary patterns is essential for effective public health strategies.
