Multicenter Study Comparative Study
Triggering Receptor Expressed on Myeloid Cells-2 (TREM-2) expression tracks with M2-like macrophage activity and disease severity in COPD.
Cell and animal models show a key role for Triggering Receptor Expressed on Myeloid Cells (TREM)-2 in chronic airway disease after viral infection, but comparable evidence in humans still needs to be established. ⋯ TREM-2 expression is increased in lung macrophages in COPD, particularly in comparison with TREM-1. Therefore, TREM-2 levels and the ratio of TREM-2/TREM-1 signifies M2 activation in COPD lung tissues and may help to guide therapeutics directed against the type 2 immune response in patients with this disease.

Scarce Resource Allocation during Disasters: A Mixed-Method Community Engagement Study.
During a catastrophe, health-care providers may face difficult questions regarding who will receive limited life-saving resources. The ethical principles that should guide decision-making have been considered by expert panels but have not been well explored with the public or front-line clinicians. The objective of this study was to characterize the public's values regarding how scarce mechanical ventilators should be allocated during an influenza pandemic, with the ultimate goal of informing a statewide scare resource allocation framework. ⋯ The values expressed by the public and front-line clinicians sometimes diverge from expert guidance in important ways. Awareness of these differences should inform policy making.
