Productivity loss is an overlooked aspect of the burden of chronic health conditions. While modern guidelines emphasize achieving clinical control in asthma management, few studies have reported on the relationship between asthma control and productivity loss. We calculated the productivity loss that can be avoided by achieving and maintaining clinical control in employed adults with asthma. ⋯ Our results indicate that substantial gain in productivity can be obtained by achieving asthma control. Presenteeism is more responsive than absenteeism to asthma control, and, thus, is a more important source of preventable burden.

Parasitic infestations affect millions of the world's population. Global immigration and climate change have led to changes in the natural distribution of parasitic diseases far removed from endemic areas. ⋯ Pulmonologists need to become familiar with the epidemiology, clinical presentation, pathophysiologic characteristics, and bronchoscopic findings to provide proper management in a timely fashion. This review provides a comprehensive view of both helminthic and protozoal parasitic diseases that affect the respiratory system, especially the airways.

Comparative Study
Leveraging a critical care database: SSRI use prior to ICU admission is associated with increased hospital mortality.
Observational studies have found an increased risk of adverse effects such as hemorrhage, stroke, and increased mortality in patients taking selective serotonin reuptake inhibitors (SSRIs). The impact of prior use of these medications on outcomes in critically ill patients has not been previously examined. We performed a retrospective study to determine if preadmission use of SSRIs or serotonin norepinephrine reuptake inhibitors (SNRIs) is associated with mortality differences in patients admitted to the ICU. ⋯ We found significant increases in hospital stay mortality among those patients in the ICU taking SSRI/SNRIs prior to admission as compared with control subjects. Mortality was higher in patients receiving SSRI/SNRI agents that produce greater degrees of serotonin reuptake inhibition. The study serves to demonstrate the potential for the future application of advanced data examination techniques upon detailed (and growing) clinical databases being made available by the digitization of medicine.

Multicenter Study
Duration of benefit in patients with autoimmune pulmonary alveolar proteinosis after inhaled GM-CSF therapy.
Treatment of autoimmune pulmonary alveolar proteinosis (aPAP) by subcutaneous injection or inhaled therapy of granulocyte-macrophage colony-stimulating factor (GM-CSF) has been demonstrated to be safe and efficacious in several reports. However, some reports of subcutaneous injection described transient benefit in most instances. The durability of response to inhaled GM-CSF therapy is not well characterized. ⋯ These results demonstrate that inhaled GM-CSF therapy sustained remission of aPAP in more than one-half of cases, and baseline %VC might be a prognostic factor for disease recurrence.

Whether Native American ancestry (NAA) is associated with COPD or lung function in a racially admixed Hispanic population is unknown. ⋯ NAA is inversely associated with COPD but positively associated with FEV1 or FVC in Costa Ricans. Ancestral effects on smoking behavior partly explain the findings for COPD but not for FEV1 or FVC.
