The objective was to estimate D-dimer interval likelihood ratios (iLRs) for diagnosing pulmonary embolism (PE). ⋯ A decision strategy based on these approximate iLRs agrees with several published strategies.

Multicenter Study
Emergency Department Vital Signs and Outcomes after Discharge.
Vital signs are critical markers of illness severity in the emergency department (ED). Providers need to understand the abnormal vital signs in older adults that are problematic. We hypothesized that in patients age > 65 years discharged from the ED, there are abnormal vital signs that are associated with an admission to an inpatient bed within 7 days of discharge. ⋯ While we found a majority of patients discharged with abnormal vital signs as defined by the analysis, not to be admitted after discharge, we identified vital signs associated with at least twice the odds of admission.

Multicenter Study Observational Study
Utility Of Serum Biomarkers In The Diagnosis and Stratification Of Mild Traumatic Brain Injury.
The objective was to compare test characteristics of a single serum concentration of glial fibrillary acidic protein (GFAP), S-100β, and ubiquitin carboxyl terminal hydrolase L1 (UCH-L1), obtained within 6 hours of head injury, to diagnose mild traumatic brain injury (mTBI) in head-injured subjects. ⋯ A single serum concentration of GFAP, UCH-L1, or S-100β within 6 hours of head injury may be useful in identifying and stratifying the severity of brain injury in emergency department patients with head trauma, but cannot reliably exclude a diagnosis of concussion. A positive GFAP was associated with the presence of concussion.
