Asthma is a common inflammatory disease affecting the airways that leads to shortness of breath, coughing and wheezing. Symptoms range from mild to severe but are generally manageable with appropriate treatment.

When asthmatics come into contact with something that irritates their lungs, three main changes occur that prevent air from moving easily through the airways. The bands of muscle surrounding the airways tighten and narrow the airway (bronchospasm), the lining of the airways inflame, and the cells that line the airways produce more mucus. This bronchospasm, inflammation, and mucus production lead to wheezing, coughing and difficulty in breathing.

An asthma “attack” refers to when the onset of symptoms is severe. In rare cases, an asthma attack can be life threatening and hospitalization may be required to provide emergency treatment.
The exact cause of asthma is not yet clear, but examples of factors that are known to trigger the condition include allergens such as house dust mites or pollen, cigarette smoke, exercise, chest infections, and exposure to cold air.

Asthma cannot be cured but it can be controlled. One of the most important parts of asthma control is identifying asthma triggers so they can be avoided wherever possible. Medications that may be used include anti-inflammatories to reduce swelling and mucus production and bronchodilators to relax the muscles that tighten and narrow the airways.

Research roundup: Prevention services for seniors; drug shortages

This policy brief reports the findings of a systematic review conducted by the Community Health Innovations in Prevention for Seniors (CHIPS) project. ... Clinical preventive services such as colorectal cancer screening and pneumococcal immunization can help reduce rates of premature death and disability. Yet, many older adults are not receiving the full set of clinical preventive services that have been proven effective and are considered "high value" in terms of their costs per life saved. Rates are particularly low among racial and ethnic minority older adults compared to national goals. [More]
