Summary
Adenotonsillectomy (AT) rates in Taiwan are low but pediatric AT incidence increased from 1997-2010. Changing indications include rising obstructive and neoplastic cases, with age and hospital level being key factors.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Health Services Research
Background:
- Adenotonsillectomy (AT) is a common surgical procedure for children and adults.
- Understanding trends in AT incidence and indications is crucial for healthcare planning.
Purpose of the Study:
- To assess factors associated with changes in adenotonsillectomy incidence and indications.
- To analyze population-level data on AT procedures in Taiwan.
Main Methods:
- Retrospective cohort study utilizing the Taiwan National Health Insurance Research Database (1997-2010).
- Examination of surgical rates and indications stratified by age, sex, hospital level, and geographic residence.
- Logistic regression analysis to identify significant correlating factors.
Main Results:
- The average annual AT incidence was 14.7 per 100,000 individuals.
- Pediatric AT rates showed an increasing trend (1997-2010).
- Adult AT saw decreasing infectious and increasing neoplastic indications, while pediatric AT showed increasing obstructive indications.
Conclusions:
- Taiwan's AT rate is lower compared to other countries.
- Pediatric AT incidence rose, with obstructive indications increasing.
- Age and hospital level significantly influenced changing AT indications in adults and children, respectively.

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Cardiovascular diseases, encompassing a range of conditions, can significantly affect the heart's operations and the overall circulatory system. These conditions impair the heart's ability to pump blood, leading to a deficit in oxygen supply to crucial organs. Anomalies in the heart's electrical system, known as arrhythmias, can cause heartbeats to accelerate or slow down. Usually, heart rates increase during physical activity and decrease while resting or sleeping. However,...

01:25What is Population Genetics?
64.9K
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.

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.
