Psychoneuroimmunology: Diabetes and Cancer01:19

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
Drug Dosing: Geriatric Patients01:15

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...
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...
Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
Aging01:26

Aging

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 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...

    Area of Science:

    • Gerontology
    • Epidemiology
    • Oncology

    Background:

    • Global population is aging, leading to increased cancer incidence and prevalence in elderly individuals.
    • Cancer affects elderly populations disproportionately, necessitating a deeper understanding of incidence patterns.

    Purpose of the Study:

    • To analyze geographic and ethnic variations in cancer incidence among elderly populations worldwide.
    • To identify distinct patterns of cancer incidence with advancing age across different global regions.

    Main Methods:

    • Utilized international cancer incidence data from the International Agency for Research Against Cancer (IARC).
    • Analyzed cancer sites commonly affecting the elderly population.
    • Applied statistical tests to characterize incidence patterns and male/female ratios.

    Main Results:

    • Western societies exhibit a higher proportion of cancer patients aged 65 and above, even after adjusting for age distribution.
    • Identified three distinct patterns of cancer incidence with age: continuous increase (Western countries), peak and decline (less prosperous European nations), and plateau (developing countries).
    • Observed higher male/female ratios in the elderly, primarily due to earlier onset of gynecological cancers.

    Conclusions:

    • Cancer incidence patterns in the elderly are diverse globally, influenced by factors beyond etiology, such as healthcare quality and social norms.
    • The aging global population underscores the growing need for resources and specialized care for elderly cancer patients.
    • International variations in cancer distribution among the elderly highlight the impact of healthcare systems and societal factors.
