Summary
Population aging increases COVID-19 cases and deaths, especially in older males. Developing nations face higher mortality risks, highlighting the need for targeted public health policies.
Area of Science:
- Gerontology
- Epidemiology
- Public Health
Background:
- Population aging is a global demographic trend.
- National development levels vary significantly worldwide.
- Understanding disease dynamics in diverse populations is crucial for effective health policy.
Purpose of the Study:
- To investigate how population aging and national development influence COVID-19 progression.
- To inform preparedness strategies and policy development for novel coronavirus disease.
Main Methods:
- Multisource data from the World Bank and Johns Hopkins COVID-19 Dashboard were utilized.
- Regression analysis was performed to assess associations.
Main Results:
- Population aging correlated positively with confirmed COVID-19 cases at days 10, 20, and 30.
- Association between population aging and mortality emerged by day 20.
- Higher proportions of older males, particularly aged 70-74, indicated increased risk for cases and deaths.
- National development level did not affect case numbers, but developing countries showed higher mortality risks at days 10 and 20.
Conclusions:
- Targeted prevention and control policies are needed for older adults.
- Underdeveloped areas require specific attention in public health strategies.
- Further research into sex-based differences in COVID-19 outcomes is warranted.

01:26Factors Affecting the Risk of Infection
13.0K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:27Pharmacodynamics in Geriatric Patients: Effects of Age
93
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...

01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
81
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...

01:15Drug Dosing: Geriatric Patients
102
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...

01:18Factors Affecting Illness
4.8K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
67
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...
