Summary
Environmental factors like weather and air pollution are linked to nosebleeds (epistaxis). However, these associations differ significantly across age groups, necessitating age-specific analyses for better understanding and prevention strategies.
Area of Science:
- Environmental Health
- Epidemiology
- Otorhinolaryngology
Background:
- Epistaxis (nosebleeds) is known to be influenced by environmental factors.
- Previous research has not specifically evaluated age-dependent relationships between environmental exposures and epistaxis.
Purpose of the Study:
- To investigate the association between meteorological factors and air pollutants with epistaxis.
- To analyze these associations distinctly across different age demographics.
Main Methods:
- Retrospective cohort study of 46,628 patients diagnosed with epistaxis.
- Patients were stratified into four age groups: <18, 18-40, 41-70, and >70 years.
- Stepwise logistic regression was used to identify environmental risk factors for epistaxis within each age group.
Main Results:
- Relative humidity, temperature, PM10, sulfur dioxide, sunshine duration, and wind speed were significantly associated with epistaxis overall.
- Key environmental factors and air pollutants linked to epistaxis varied considerably among the four age groups.
- The youngest age group (<18 years) had the highest incidence of epistaxis, while the oldest (>70 years) had the lowest.
Conclusions:
- Environmental risk factors for epistaxis are not uniform across all age groups.
- Age-specific analysis is crucial for understanding and managing epistaxis related to environmental exposures.

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

01:20Gene-Environment Interactions
407
Gene expression is a dynamic process that is significantly influenced by environmental factors. This interaction underlies the complex nature of biological development and the phenotypic differences observed among individuals, even among those with identical genetic makeups. Factors such as radiation, temperature, behavior, nutrition, and stress play pivotal roles in determining how genes are expressed. The concept of the reaction range is central to understanding this interaction. It posits...

2.8K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

02:27Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

01:26Factors Affecting the Risk of Infection

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...

6.3K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
