Review Meta Analysis
Accuracy of Biomarkers for the Diagnosis of Adult Community-acquired Pneumonia: A Meta-analysis.
Biomarkers such as C-reactive protein (CRP) and procalcitonin may help distinguish community-acquired pneumonia (CAP) from other causes of lower respiratory tract infection. ⋯ The best evidence supports CRP as the preferred biomarker for diagnosis of outpatient CAP given its accuracy, low cost, and point-of-care availability.

Randomized Controlled Trial
Ibuprofen + acetaminophen versus ibuprofen alone for acute low back pain. An ED-based randomized study.
Patients with low back pain (LBP) are often treated with nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs are modestly effective for LBP, but many patients with LBP continue to suffer despite treatment with these medications. We compared pain and functional outcomes 1 week after emergency department (ED) discharge among patients randomized to a 1-week course of ibuprofen plus acetaminophen versus ibuprofen plus placebo. ⋯ Among ED patients with acute, nontraumatic, nonradicular LBP, adding acetaminophen to ibuprofen does not improve outcomes within 1 week.
