Case Reports

A 31-year-old woman (gravida 3 and para 1-0-1-1 at 20 weeks gestation) was admitted to the hospital for a presumed acute asthma exacerbation. She had a history of severe persistent asthma since childhood. She described her symptoms as progressively worsening since the beginning of her pregnancy. ⋯ She had a social history of alcohol dependence but had been sober for 9 months. She was a former one-pack-per-day smoker but quit 20 weeks before admission and used marijuana occasionally. She had no known occupational or inhalation exposures.

Randomized Controlled Trial
Prenatal and Postnatal Household Air Pollution Exposures and Pneumonia Risk: Evidence From the Ghana Randomized Air Pollution and Health Study.
Nearly 40% of the world's population is exposed daily to household air pollution. The relative impact of prenatal and postnatal household air pollution exposure on early childhood pneumonia, a leading cause of mortality, is unknown. ⋯ Prenatal household air pollution exposure increased risk of pneumonia and severe pneumonia in the first year of life. Clean-burning interventions may be most effective when begun prenatally.

Practice Guideline
Screening for Lung Cancer: CHEST Guideline and Expert Panel Report - Executive Summary.
Low-dose chest CT screening for lung cancer has become a standard of care in the United States, in large part because of the results of the National Lung Screening Trial (NLST). Additional evidence supporting the net benefit of low-dose chest CT screening for lung cancer, and increased experience in minimizing the potential harms, has accumulated since the prior iteration of these guidelines. Here, we update the evidence base for the benefit, harms, and implementation of low-dose chest CT screening. We use the updated evidence base to provide recommendations where the evidence allows, and statements based on experience and expert consensus where it does not. ⋯ Evidence suggests that low-dose CT screening for lung cancer can result in a favorable balance of benefit and harms. The selection of screen-eligible individuals, the quality of imaging and image interpretation, the management of screen-detected findings, and the effectiveness of smoking cessation interventions can impact this balance.
