Popcorn Lung – Medical Definition
Read the medical definition of popcorn lung. Popcorn lung is caused by chronic exposure to a chemical called diacetyl used to create the buttery flavor of popcorn, and the flavoring in some e-cigarettes.

Death by popcorn.
The syndrome has also been observed in people who consumed microwaved popcorn in large quantities.
Treating Asthma in Older Women | Physician’s Weekly
Among older individuals, women are significantly more likely than men to report having asthma and also have a 30% higher asthma-related mortality rate. In addition, women are nearly twice as likely to visit the emergency department for asthma when compared with men. Older women have been shown to have the highest hospitalization rates among all people with asthma (Figure). “However, little is known regarding why older women are more likely to suffer from the adverse events of asthma,” says Alan P. Baptist, MD, MPH. To better understand the specific issues that are unique to older women with asthma, Dr. Baptist and colleagues conducted a literature review and published their findings in Annals of Allergy, Asthma, & Immunology.
Sleep Apnea Linked to Cancer
Moderate-to-severe OSA was associated with a 2.5-fold higher likelihood of incident cancer (95% CI 1.2-5.0) after adjustment for obesity and a full range of other factors, Nathaniel Marshall, PhD, of the University of Sydney Nursing School in Australia, and colleagues found.
Cancer mortality was 3.4 times more common (95% CI 1.1-10.2) in those with sleep apnea than with no sleep apnea during 20 years of follow-up, they reported in the April 15 issue of theJournal of Clinical Sleep Medicine.
Sleep Apnea Severity Tied to Cardiac Marker
- Obstructive sleep apnea is associated with cardiovascular morbidity and mortality, particularly heart failure, a study found.
- The severity of obstructive sleep apnea was significantly associated with higher levels of high-sensitivity troponin, suggesting that subclinical myocardial injury may play a role in the association with risk of heart failure.
Artery Damage Seen in Sleep Apnea
People with obstructive sleep apnea (OSA) have subclinical arterial disease on par with that seen in patients with diabetes, researchers found.
Patients with moderate to severe obstructive sleep apnea have endothelial dysfunction and arterial stiffness, similar to patients with diabetes mellitus.

Small study with some interesting findings.
Reduced Total Lung Capacity and Mortality
Background: Pulmonary restriction is associated with increased mortality in adults, especially those who are elderly. Previous studies, however, have used the FVC as a surrogate for the total lung capacity (TLC). We evaluated the association between a reduced TLC, mortality, and health-care resources use and compared this association with a reduced FVC.
Conclusions: Reduced TLC is strongly associated with mortality in adults who are elderly. Reduction of the FVC is a weaker risk factor for mortality.

Biomarkers Help Predict COPD Prognosis
This study found that in patients with chronic obstructive pulmonary disease COPD a panel of biomarkers can improve mortality predictions beyond that of clinical factors.
